Oxfam Operational Management

The purpose of this assignment is to apply the main theories within operations management to summaries and critically evaluate the main issues facing Sofas within the following strategic and operational contexts: l. Globalization and International management II. Environmental management Ill Social responsibility lb. Technology v. Knowledge Management Figure 1 The Operations Strategy and Management model (Slack, N. , Chambers, S. , Johnston, R. , 2007) 1 Sofas Background Information The name Sofas comes from the Oxford Committee for Famine Relief, founded in Britain in 1942 during Second World War.Sofas International was formed in 1995 by a group of independent non-governmental organizations. Sofas is an independent organization affiliated to Sofas International, a global confederation of 14 independent Sofa's (www. Spam. Org). In 2010 Sofas was working in 99 countries. Sofas works directly with communities to find and influence solutions to poverty and injustice (www. Sofas. Org). So fas are working on development programs, emergency work and research. In 1948 Sofas opened its first charity shop. Sofa's current network of more than 830 charity shops are run by about 22000 volunteers and are a key source of income.Orders can be made by mail or over the Internet. Sofas teamed up with Yahoo! (Carroll, 2010) Sofas has an annual expenditure of US $700 million and employs around 1300 staff, of whom around 700 are based in Oxford, I-J, ND the others, together with about 1 500 locally recruited staff, work overseas. Sofas is best known for its work in emergency situations providing humanitarian aid where it is needed. However much of Sofa's work continues after the initial response. Sofa's Strategic plan 2007/10 underlines five main objectives (www. Sofas. Erg): The right to a sustainable livelihood The right to basic social services The right to life and security The right to be heard The right to equity (gender and diversity) The above describes Sofa's mission stateme nt â€Å"A world without poverty and equal human rights for all people†. The Although all operations are similar, they all transform input resources into output products and services, they do differ (Slack, 2007). The Four Vs. – Volume, Variety, Variation and Visibility, have implications for the cost of product, or in case of Sofas service, to its beneficiaries.As Sofas is a non profit organization and the interest is provide improvement of lives and fast response to natural and political disasters in Third World Countries, it could be said that their success could be measured in how well tenet support Ana Involvement rennet's on loveliness AT tense teen are knelling o. The Volume for Sofas is measured by the improvement of living conditions, by how many people have an access to clear water or how many lives are saved after a natural disaster. Sofas is involved in many projects therefore the Variety should be seen as high.However due to the nature of the work Sofas do es and the help they provide, the variety demands high level of flexibility from Sofas, its employees and volunteers. In the case of a charity the Variation should be relatively low. And many charity organizations are concentrating on to one issue only. However Sofas is known for heir involvement in many projects and can offer help in various situations, natural disasters, political rows in countries of the third world, where many people are being denied a decent living.As well as providing safe water projects around the world, building schools and many others. Sofa's Variation is therefore higher than many other charities but still would not be consider high as in a profit organization. Due to the nature of raising money for their operations via their shops, appeals and various projects, the Visibility of Sofas and its people is high. The argument could be hat Sofas has more back office staff than front office and therefore the visibility is not as high. However such an argument ca n be dismissed based on the overall focus on Sofas.The contact with people is necessary for the nature of the business. Sofa's 4 Vs. summarizes in Figure 2. [pick] Figure 2 The 4 ‘v†s module in relation to Sofa's operations Operations performance objectives There are five basic performance objectives which apply to all type of organizations (Slack, 2007). These objectives specifically relates to a basic tasks of satisfying customer requirements. Every organization has stakeholders who have a high interest in its operations. As per Slack Sofa's stakeholder groups can overlap.Sofa's volunteers who work in charity shops could also be employees as well as customers. Therefore a not for profit organizations who are influenced by more complex factors which they can not affect such as natural disasters, has to even more so define its operation's role, position and operation strategic objectives to show their stakeholders how they perform. The five objectives are quality, speed, dependability, flexibility and cost. Sofas aims to deliver high quality in each situation and project they are involved in.The quality s measured by the satisfaction of customers however in Sofa's case the satisfaction is not going to be reflected the same way as satisfaction with product or service of companies who produce these for profit. Sofa's customers are in many cases highly satisfied with a bare minimum of life standards and the help they receive. However quality coo a De considered Trot ten way AT Improvements AT humans' lives and livelihoods and its sustainability. Speed is something that is of a very high importance for Sofas. To respond fast to natural and other disasters is number one priority.The speed of the response could mean the difference between life and death. However improvement of women's rights and Sofas project of bringing education to all is anything but a speedy as the importance is to stabilize the changes first to make sure they are going to be permane nt improvements to their lives. For Sofas stakeholders dependability is a very important factor. For the people who receiving the help and support it is important to know that the support will be there and it is not Just a promise. For the volunteers and people who donated it is important to see that changes are being made and support is being given.Flexibility is the highest priority. Sofas is not only involved in various projects around the world but also needs to be able to change their plans and actions to respond fast to many situations such as political changes within the country where they providing their support. Or in the case of natural disaster, Sofas needs to be ready to respond fast, to provide basic supplies for humanitarian support. Their employees and volunteers need to be flexible to react quickly to safe lives and livelihood. Operations have to change at short notice.Even the charity shops which are mostly stable operations have to be flexible and sometimes change their operations to respond to situation in the world. In the case of natural disasters the nature of donations needs to change, not only cash donations are required but food, clothes or blankets. Cost is a very difficult measurement for a charity organization. It is important to keep its costs down to achieve more with the money raised however in many situations it is not about keeping the cost low but about saving lives, providing fast response and help when its needed and this can drive cost up.With natural disaster it is not important the amount invested in to the help but the help that is provided. When people loose everything even a little amount of help and support is highly appreciated and therefore the cost is not of a high importance. Figure 3 Sofa's Polar Diagram The role of operations Operations management can make or break any business (Slack, 2007). Hayes and Wheelwright's four stages of operations contribution evaluate the role and contribution of the operations funct ion (Slack, 2007). Sofa's operations are at stage 4.Sofas does compete with other charities for donations and volunteers. However, where other charities offering food and money, Sofas offers lives stock, seeds, smelter, coeducation anon T s well as money winner teen are name (www. Sofas. Org). Sofas gets involved in peoples live for longer to assure long term improvements in their livelihoods. Figure 4 The four stage model of operations contribution. Operations Strategy Operations strategy concerns the pattern of strategic decisions and actions which set the role, objectives and activities of the operations (Slack, 2007).Sofa's operation strategy is to reduce and eliminate the causes of poverty and suffering (www. Sofas. Org). As an objective the Sofa's 5 Aims are used to build the operations strategy, the top down perspectives. The bottom up perspective is reflected in improvement for the next project Sofas gets involved as the knowledge management aspects will affect how the next operation is managed. Market requirements are reflected in the numbers of people Sofas has helped to rebuild their lives. However for a not for profit organization the strategy is more complex and is affected by The Operations Challenge.Figure 5 The four perspectives on operations strategy The Operations Challenge Although operations management is seen by some as being concerned largely with the routine aspects of business, it is in fact at the very forefront of almost all equines challenges (Slack, 2007). There are many changes that the operations management needs to understand, be concerned with and adjust to. The challenges and changes in the world can be seen as a positive change which helps with Sofa's 5 Aims detailed in section 1. 1 and in appendix 1 .These are highly affected by many challenges and operations managers should be familiar with Sofa's Aims and developments to be able to apply appropriate strategies. 1 Globalization With opening of new international market were o pened many new opportunities for operations managers to develop supplier relationships (Slack, 2007). Important for Sofas as the need to have a fast and affordable access to supplies all around the world, to be able to respond fast is high on their operations strategies. The Ethical globalization affects Sofa's political affluence and it works well with ethical approaches.Acknowledging shared responsibilities for addressing global challenges and affirming that our common humanity does not stop at national borders (Slack, 2 Corporate Social Responsibility In a modern business there is more and more pressure on to the general well-being of society. Economic development on a global level cannot be separated from questions of social Justice and from ecological stability (Discarding, cited in Walleye, 2008). It is a nature of Sofas business to assure that all humans are being treated with respect and as equals.As per Sofas, nobody should compromise on their human rights. Sofas provides a ssistance and protection to ordinary men, women and children caught up in conflict or natural disasters (www. Sofas. Org). It is Sofa's believe that all people have social, economic, political and civil rights as well as rights under humanitarian law (www. Sofas. Org). Not only Sofas provides provisions of eater, sanitation and hygiene promotion they also lobby governments and the international community to live up to their responsibilities to protect civilians (www. Sofas. Org).However it needs to be considered that what might be unremarkable in one country ethical framework could be regarded as highly dubious in another's (Slack, 2007). 3 Environmental Responsibility Environmental Responsibility is getting on to an agenda of any organization. Sofas is highly involved in campaigning for Climate Change. During 2010 over 1. 5 million people in 35 countries attended Climate Hearings organizes by Sofas and its ratters (www. Sofas. Org). These are organizes by Sofas to voice directly to global policy environments the reality of Global warming and its effects on to those living in poverty.Sofas is committed to reduce their carbon footprint by setting and delivering yearly targets (www. Sofas. Org). 4 Technology Technology has impact of some sort in almost every area of operations management (Slack, 2007). Internet has the biggest impact on how the business operates. Sofas improved their engagement with their supporters due to internet and other digital communications (www. Sofas. Org). This has resulted in to increase in online donations to over E. Mm in 2010. Sofas therefore invests more of their resources in to improvement of their website.Technology is also changing the ways Sofas International works. Introduction of Single Management Structure is a big step which wouldn't be possible without constant changes in technology. Supply network is also more simple and faster due to new technologies. Technology has a huge impact on to Sofas operations and the speed the y can reach people in need. 5 Knowledge Management Knowledge is rich, interpretative and often value-laden. In very complex operations recesses, It may De almost Impossible to make ten totality AT Knowledge concerning processes fully and entirely explicit (Slack, 2007).Sofa's operations the explicit knowledge is not possible. Sofas knowledge management is build over time and is a result of Sofas experience in various projects and responses to different situations. Sofas therefore employs the Tacit knowledge. Tacit knowledge may be observed and accumulated over time (Slack, 2007). Sofa's strategies are changing based on their understanding of how the world is changing for poor people and what the best response to it would be (www. Sofas. Erg). Sofas needs to understand these changes and react with agility and effectiveness to maximize their impact on to poor people.By improving knowledge management Sofas improves disaster preparedness and response the main purpose of their business. Being an international organization that responds to human needs anywhere in the world it is highly important for Sofas to have a local knowledge. Supplies, its availability and access to it, are a need for Sofas and the knowledge of local suppliers is strategically important. Sofas is building team of trainers and experts to implement their new system around the oral (www. Sofas. Org).Security of their aid workers a knowledge of political situations and predictions in many parts of Third World countries is necessity. Supply Network Every operation is a part of a larger and interconnected network of other operations. Supply network will include suppliers and customers (Slack, 2007). As Sofas works all around the world and has to be able to respond fast to a natural disaster it has to consider many ways of supply. Design decisions of Sofas supply network are important agenda for its operations and supply managers. Sofas supply planning is very unpredictable.They have a network of sup pliers they working with to make sure they are able to react fast to any natural disaster. However to work with the affected community in a longer term they need to be able to find new suppliers in a very short time period who are closer to the area of disaster and can supply the needs of the situation. Attachment 1 states Sofa's supply policy in detail. In the policy Sofas is not only concentrating on to its supply and demands but also concentrate on to the operations challenges as described in section 4 of this assignment.The nature of Sofa's work means inventory problems. It is not cost efficient to keep a large amount of supply on hold in case of an emergency. Keeping too much could resolve in high cost related to storage. Keeping too little could mean that when there is a natural disaster and speedy response is needed, there is not enough of basic supplies such as water, food and blankets. In 2009/10 Sofas has rolled out new software tool knows as Hellos (www. Sofas. Org) to he lp with delivering the right supplies, in the appropriate amount, at the best cost, on time to the people who need it the most.It will provide a real time overview of what Sofas has, where it is and owe efficiently it can be moved to where it is needed. Conclusions It can De concluded Tanat even tone oxtail Is a not Tort pronto organization teen 00 understand the importance of operational management and strategies and acting upon it. Sofas sets clear strategies and reviews them every year. It acts upon the need of updating their operation strategies. The core business of Sofas operations is help to people who are in a need of help and support. Its 5 aims are stated and in their Annual report Sofas clearly states percentage of charitable expenditure.However looking closely on everything that Sofas was involved in over the 2010 eroded, it is clear that the greater the need the faster the response and the less important the money involved in the initial response are. Sofas has set proj ects over the period of time and with regards to these it is easy to apply operational strategies and management. It is when a natural or political disaster happen that Sofa's operations change in priority. Sofas has to be highly flexible to be able to fulfill its promises to all its stakeholders. The five performance objectives and its importance are changing. They are affected by outside forces.There is a need of constantly improving its services and overview its operations strategies to avoid failure in delivering its promise. Sofas works in constantly changing world therefore the operations within Sofas are not only important to keep its cost down but are important for the delivery and action of Sofas motto together we will end poverty. Recommendations Sofas has dedicated supply policy. However their policy does not specify how Sofas improves on smoothness of their supply and costs involved with it. In 2009 Sofas has introduced a system that unites all its international organiza tions.

The Shoe-Horn Sonata Essay

Music and sound effects: Sonata is a musical term describing something written specifically for two musical instruments Music is a linking device throughout the play Sonata is symbol that occurs throughout the play Bridie and Sheila burst into song at the end of the first interview session Their performance effectively takes us back to her past Aurally (what one hears) and visually historical information is conveyed When Jerusalem reaches a crescendo, scene of the Japanese invasion are juxtaposed on the backdrop screens, ironically contrasting image and triumphal song Lacking real instruments, we are told the prisoners had to improvise using their voices alone Even when numbers were decimated and the choir couldn’t sing anymore Bridie and Sheila fill the gap They thought â€Å"It was up to us to carry on†¦ we sang our sonata whenever we could so the camp would know there was still music left† Music becomes pivotal to their survival Music is an aural symbol of willpower and determination We’d sit in our hut at night and hum. â€Å"We’d do it while we dug the graves†. Bridie laconically observes, â€Å"It probably sounded bloody awful. But not to us. To us we still had harmony†¦ and the ‘japs’ could never take that away. Voice and spirit are fused, â€Å"We forgot the Japanese – we forgot our hunger – our boils – barbed wire – everything†¦ Together we made this glorious sound that rose about the camp- above the jungle-above the war-rose and rose and took us with it† Sheila also sums up its psychological importance, â€Å"Fifty voices set us free† Sound effects add atmospheric detail and mood ïÆ'   An example is in the opening at where the women describe the sinking of the ship or machine gunning of helpless women and children, â€Å"We hear the distant sound of lapping waves† Projected Images: Visual reinforce the script, the use of photographic images reinforces the context and historic authenticity of what is being said. Evocative glimpses  through slides of ships burning in Singapore Harbour, the Japanese invasion and the shocking conditions of the prisoners of war. Distinctively visual methods are used to allow the audience to witness the horrific reality of the period – This augments the simple set design and the use of a two character cast while helping develop the plays irony and humour – This is evident when images released by the Australian Defence Department, showing healthy, clean and happy women are dramatically juxtaposed with those that showed them as they were liberated Lighting and Stage Directions Light is a key dramatic device that helps develop themes and characters Misto supplies detailed stage directions which specify tone, mannerisms or line delivery to create a particular mood or atmospheric context Directions such as ‘fondly’, ‘slightly surprised’ disapprovingly, ‘very calmly’ ‘ironic smile’ ‘casually trying to make light od it’ position the audience’s interpretive response They also focus attention on Sheila and Bridie’s emotions, building tension and suspense as their relationship fluctuates. The opening stage directions read: â€Å"darkness. Out of the silence comes the voice of Bridie† and after her first line of dialogue, she is visually spot lit. Stage lighting gradually reveals the ‘on air’ sign establishing our perception of the TV studio context The interplay of light and dark, via spotlighting, blackouts and fade outs, help develop atmosphere or mood for the rest of the play When Bridie and Sheila are emotionally separated, they are often lit separately, whereas once reconciled by the end of the play. They are lit in partnership. As they dance, the light gradually fades away, while a ‘very bright spot light’ highlights the shoehorn – This visually signifies its symbolic importance as something that first brought them together, then forced them apart, and now, once again, reunites them.

Pleurotus spp

The fungi are a group of eukaryotic organisms. Due to their microscopic cellular dimensions, they are of great interest to microbiologists. Multicellular fungi is familiar to each and every one of us. The velvety blue and green growth on rotting oranges and lemons as well as on stale cheeses, the whitish grey furry outgrowth on bread and Jam, and the mushrooms in the field. These are the bodies of a variety of fungi. Fungi are heterotrophic organisms†They need organic compounds for nutrition.The classification of fungi, unlike that of bacteria, is based primarily on the hracterstics of the sexual spores and fruiting bodies, present during the sexual stages of their life cycle. However, the sexual spores and fruiting bodies are produced only under certain environmental conditions, if they are known to produce them at all. Pleurotus is a genus of gilled mushrooms which includes one of the most widely eaten mushrooms. Species of pleurotus may be called oyesters, abalone or tree mu shrooms and are some of the most commonly cultivated edible mushrooms in the world.They have been very much useful in mycoremediation of pollutants such as petroleum and polycyclic aromatic ydrocarbons. The name pleurotus has been derived from the greek word pleure (side) + otos (ear) which means â€Å"Side Ear†. The following are the details of Pleurotus Genus scientific classification: l. The kingdom of pleurotus is Fungi, II. Phylum is basidiomycota, Ill. class is Agaricomycetes ‘V. Order is agaricales V. Family is pleurotaceae The basic structure of oyster mushroom includes a capwhich may be laterally attached (with no stem).If there is a stem, it is normally eccentric and the gills are extended downward along it. The term pleurotoid is used for mushrooms having this eneral shape. There are certain cylindrical spores which are smooth and elongated. Where hyphae meet, they are Joined by clamp connections. Pleurotus is not considered to be a bracket fungus and most of the species are monomitic (with a soft consistency). Pleurotus Ostreatus Specifications Scientific name: Pleurotus ostreatus Oacq. ) P. Kumm. Derivation of name: Ostre- means â€Å"oyster† and atus means â€Å"resembling. † Synonyms: Agaricus ostreatus Jacq.Common name(s): Oyster mushroom. Phylum: Basidiomycota Order: Agaricales Family: Pleurotaceae Occurrence on wood substrate: Saprobic or parasitic; olitary to more typically in overlapping clusters on living or dead deciduous trees, on rotting logs and stumps, sometimes on conifers; April all the way through November, year-round during mild periods. Dimensions: Caps 5-20 or more cm wide; stipes 0. 5-4 cm long and 0. 5- 3. 5 cm thick. Stripes may be absent. Cap: Moist or dry; smooth; variable in color: whitish to cream, greyish to brown, some with lilac tones; oyster shell- shaped to fan-shaped or semicircular.Gills: Decurrent or glowing from point of attachment; broad; whitish, yellowish in age. Spore print: White t o pale lilac-gray. Stipe: Sometimes absent or rudimentary. If present, lateral to eccentric or even central if fruitbodies are on top of a log or stump; whitish; hairy at base. Veil: Absent. Edibility: Edible, rated as choice. The oyster and abalone mushrooms belong to the genus pleurotus. They have a high saprophyte colonizing ability and can grow on virtually any agricultural waste. They rank among the top six mushrooms produced in the world.It should be noted that the availability of a good strain of mushrooms, suitable substrate for cultivation and control of saprophytic and parasitic microorganisms are the three most important spects for mushroom cultivation. The world production for this genus was 169,000 tons in 1986. The consumption and production of edible mushrooms in developing countries have occurred for many years. There has been a high upsurge of interest in cultivation of this mushroom in the last decade. Because of their spicy flavour and their medical effects in dro pping plasma cholesterol, mushrooms are widely consumed in Europe, the U.S. A and Japan. Many of the fleshy sporocarp species of the many acomycetes and basidiomycetes can safely be eaten while only a few poisonous species of the fleshy fungi can be found . However more than one thousand mushrooms are known, about one hundred mushrooms are edible and only a few are considered of a commercial value. Pleurotus ostreatus is relatively easy to grow. A few trials to produce the mycelium of oyster mushrooms in Egypt using some agro industrial wastes were only recently carried out. The goal of this work was to study the cultivation of oyster mushroom (Pleurotus spp. emphasizing the effect of different media and organic substrates on production. Mushrooms of Pleurotus spp. are commonly known as oyster mushrooms which occupy the second osition among cultivated edible mushrooms worldwide due to their nutritional values. They are widely cultivated all over the world. Its production is remarkab ly affected by the environmental conditions like temperature and relative humidity. In this study, we investigated the production of four species of oyster mushroom: 1 . ) Pleurotus ostreatus 2. ) P. florida 3. ) P. aJor-caJu and 4. ) p. High king Cultivated in every season( January to December) in Bangladesh. The temperature (in C) and relative humidity (%RH) ot culture house in each month, and parameters ot ushroom production were recorded. In all of the selective study of this species, the minimum days required for primordial initiation, and the utmost number of fruiting bodies, biological yield and biological efficiency were found during December to February (14-27 oc, 70-80% RH). The production was found minimum during the cultivated time August to October.We suggested cultivation of selected Pleurotus spp. in winter (temperature zone 14-27 oc with relative humidity for better production and biological efficiency. The environmental factor is very important for the production of oyster mushrooms. Various mushrooms are known to be very sensitive to the climatic conditions. The major environmental factors like temperature, humidity, fresh air and compact materials affect in mushroom production. Pleurotus spp. grows in wide range of temperature (15-30 oc) which also varies from species to species.Oyster mushrooms Pleurotus spp. draw their nutritional requirement from a host substrate or from the agricultural wastes rich in lignin, cellulose and hemicelluloses used for their cultivation. Due to varying nutrients in the substrates, different mushroom yields have been recorded by various workers. Oyster mushrooms are grown from mycelium (threadlike filaments that become interwoven) propagated on a base of steam-sterilized cereal grain (usually rye or millet). This cereal grain/mycelium mixture is called spawn and is used to seed mush-room substrate.Most spawn is made with mycelium from a stored culture, rather than mycelium whose parent was a spore. This is beca use spores are likely to yield a new strain and performance would be unpredictable. Spawn-making is a rather complex task and not feasible for the ordinary mushroom grower. Spawn of various oyster mushroom species may be urchased from com-mercial spawn makers who usually provide instructions for its use. Spawn frequently is shipped from the manufacturer to growers in the same aseptic containers used for spawn production.Inoculum for spawn production is frequently produced in polyethylene bags containing a micro porous breather strip for gas exchange. Most commercial spawn production companies produce spawn only from inoculums that has met strict quality control standards. These standards include verification of inoculums production performance before it is used to produce spawn and assurance of the spawn's biological purity and vigour So ariable in size, shape and colour are the many kinds of oyster mushroom that confident recognition of some species is tricky without resorting to m icroscopic analysis.The process is not helped by the fruiting habit of many Pleurotusspecies that seem to delight in emerging beyond reach, sometimes high up in the crowns of trees. For the most part the various oyster mushrooms are saprophytic on deciduous trees, and only very rarely are they found on conifers. Distribution Pleurotus ostreatus, the Oyster Mushroom, occurs throughout Britain and Ireland as well as in most parts of mainland Europe. It is also widely distributed throughout much of Asia, including Japan, and is present in parts of North America.Several similar species within the Pleurotus genus are often confused, and so distribution data for individual species in this complex group are inevitably subject to some uncertainty. Taxonomic history The Oyster Mushroom was first described scientifically in 1775 by Dutch naturalist Nikolaus Joseph Freinerr von Jacquin 7) and named Agaricus ostreatus. (In the early days of fungus taxonomy most of the gilled mushrooms were inco rporated in the genus Agaricus. ) In 1871 German mycologist Paul Kummer transferred theOyster Mushroom to the genus Pleurotus (a new genus that Kummer himself had defined in 1971), giving it its currently accepted scientific name. Synonyms of Pleurotus ostreatus includeAgaricus ostreatus Jacq. , Crepidopus ostreatusoacq. ) Gray, and Pleurotus columbinus Quel. The blue-grey-capped form of this mushroom is referred to by some authorities as Pleurotus ostreatus var. columbinus (Quel) Quel. Etymology The generic name Pleurotus is Latin for ‘side ear' and refers to the lateral attachment of the stem;ostreatus is a reference to oysters, and in shape the fruitbodies often do esemble oyster shells.The specimens shown on this page show Just how changeable Oyster Mushrooms can be – not only in colour and form but also in their growing habitat. From the top: on a dead Beech trunk; next on a standing live (but surely dying) Cabbage Palm; and at last on a dead branch broken fallen f rom an old Ash tree. Importance of nitrogen sources for the growth of pleurotus spp. :- i) Nitrogen is an essential element for cellular functions, for growth and various metabolic activities, particularly protein and enzyme synthesis. i') The nitrogen content of mycelium ranges between 3-6%. i) Cereal straw used for cultivation of oyster mushroom is a poor source of nitrogen (0. 5 to 0. 8%) and at the time of fructification when most of the nitrogen is utilized for mycelia growth, the depleted nitrogen in the substrate becomes inadequate and limits mushroom yield. ‘v) In the present studies seven dissimilar nitrogen sources : wheat bran, rice bran, soya bean floor, de-oiled soya bean meal, mustard cake, cotton seed cake and cotton seed meal were evaluated for their effect on mushroom yield. v) Cotton seed cake and de-oiled soya bean meal gave significantly higher yield than unsupplemented bags.Review of literature : The oyster mushroom Pleurotus spp is a saprophytic fungus co mmercially cultivated throughout the world because of its tasty basidiocarp and simple cultivation technology. It is also one of the choicest white rot fungi for research scientists to investigate. Pleurotus spp's lignocellulolytic enzymes for bioremediation (Arisoy and Kalan Kayan 1997, Walter et. al. 1997), its flavour compounds, (Mau et. al. 1998), its synthesis of diterpene and polysaccharide (Gutirrez et. al. 1996) and its natural pigment extraction (Shirata and Kato 1998) make it a promising subject for study.Oyster mushrooms are mainly cultivated on residues from agricultural crops such as wheat, paddy, cotton, sugar cane or soybean (Sohi and Upadhyay 1989, Savalgi and Savalgi 1994). Pleurotus spp also have the potential to mineralize and grow on industrial wastes such as tea (Upadhyay et. al. 1996), apple pomace (Upadhyay and Sohi 1988) or non-conventional substrates containing lignin, cellulose or hemicellulose such as dried Populus leaves. (Upadhyay and Verma 2000). These residues are low (0. 5 to 0. 8%) in nitrogen content. Several workers have reported varying fresh oyster mushroom yields using crop residues (Sohi and Upadhyay 1987,Madan et. al. 1987). The variations may be due to the nutrient status of the substrate used for cultivation. The production of oyster mushrooms after the first flush is drastically reduced and there is a tlusn break ot 10 to 20 days depending upon the species of oyster mushroom. The yield turn down could be due to either depletion of nutrients or accumulation of toxic substances unfavourable to fruiting. In Agaricus bisporus, increased yields have been reported by supplementing with various proteins, carbohydrate or oil rich supplements like soybean meal, cotton seed meal, alfalfa meal or corn gluten meal.Sinder and Schisler 1962, Gerrits 1983). In the present studies seven different organic nitrogenous materials were evaluated to find out their effect on yield. The best substrates were further evaluated for their optima l dose with maximum yield. Materials and Methods Prewetted chopped wheat straw (2-3cm) was mixed with calcium sulphate (4% w/w) and carbendazim 50% w. p. (1 5g/quintal) and a rectangular pile prepared. It was given two turnings on alternate days for four days so that the temperature did not exceed more than 600C during fermentation.After four days, the partially fermented traw was pasteurized in a tunnel at 700C for 6h and subsequently conditioned at 450C for 36h. Supplements (wheat bran, rice bran, cotton seed meal, cotton seed cake, soybean meal, de-oiled soybean cake and mustard cake) were separately treated in a answer of carbendazim (100ppm) for 16h. The rate of adding up of all the supplements was 5% (dry wt. ) except wheat and rice bran (10%). Treated supplements were thoroughly mixed at the time of spawning with pasteurized straw. Twenty-day-old spawn of P. ostratuas var florida was added at a 3% wet wt.Five kg spawned substrate was filled into 45x30cm polyethelene bags with 10 holes (5mm ia. ). Each supplement had six replications. Spawned bags were incubated in a dark cropping room (temp. 13-18'C). Colonized bags were opened after 25 days. A relative humidity of 70-75% was maintained by spraying water twice a day; 6-8h light was provided with fluorescent tubes; and carbon dioxide concentration was maintained at 700-780 ppm in the cropping room. Mushrooms were harvested daily before spraying and data were recorded. Biological efficiency (BE) was planned on the basis of fresh mushrooms from 100 kg dry substrate weight.In the second experiment, cotton seed cake and de-oiled soybean cake were further evaluated r their effective optimum dose. The supplements were treated as before, at a rate of 1, 2. 5, 5, 7. 5 and 10% substrate dry weight. Table 1.

Soybean supplementation generally yielded heavier mushrooms in the first flush than cotton seed cake supplementation. Maximum dry matter content was recorded from bags supplemented with 5% de-oiled soybean cake and further increase in supplementation did not yield heavier mushrooms.In cotton seed cake, the heaviest mushroom truit bodies were observed with 0% dose in the first tlusn, while in the econd flush, the lowest rate of application gave the heaviest mushrooms. The dry matter content in the second flush was generally more than the first flush for both the supplements. Interestingly the spore print colour of the mushrooms from 10% soybean was a creamy yellow. The nutritional analysis of mushrooms attain from different supplements is under investigation. The addition of cotton seed cake gave the maximum yield increase (+47. 7%) while soybean cake gave heavier mushroom fruit bodies than cotton seed cak e.The use of supplementation increased the substrate temperature (Figurel and Figure 2) from the fourth day onwards to the ixteenth day. Bags with de-oiled soybean cakes showed a rise in temperature from 3 to 90C over room temperature and 3 to 50C over unsupplemented bag temperature. Cotton seed cake addition showed less temperature rise compared with similar doses of soybean cake. The utmost rise in temperature was between the fourth day and the ninth day.

D. ), Lentinula edodes (1100 A. D. and Auricularia spp (600 A. D. ), it occupies the third place in the world among the cultivated mushrooms. Successful cultivation of oyster mushroom using cereal straw was reported in 1962 by Bano and Srivastava from India. Still, it is not widely cultivated due to inconsistent yields. The fresh mushroom yield or biological efficiency of a species is directly related to strain, substrate nutrition and growth conditions. Sustainable oyster mushroom production can be achieved by employing cultural practices which optimize and integrate nutrient management.Agricultural residues used for oyster mushroom farming provide most of the nutrients and vitamins for growth. Carbon is readily available from cellulose, hemicellulose and lignin from straw, but nitrogen occurs mostly in a bound form and is not available until it is enzymatically rel eased. Various workers have also reported that Pleurotus spp have the capability to fix atmospheric nitrogen (Rangaswamy et. al. 1975, Jandaik and Rangad 1977) but this has not been proved conclusively. In the cultivation of A. isporus the addition of protein rich supplements is a common practice, which indicates that either the compost is deficient in nitrogen or the bacterial proteins present in the compost are inadequate.Rinker (1989) found 37 and 42. 6% more total yield in P. ostreatus from supplementation with barley straw with brewer's grain and 17, 27, 65 and 118% more yield by addition of alfalfa hay at 5, 10, 20 and 40% (dry wt. basis). He also found that supplementation prior to pasteurization increased the total yield, but mushroom size was negatively affected with increased supplementation. In our studies we have not found any significant effect on mushroom size. Influence of supplementation is also species and strain-specific.Somycel 3200 reacted poorly to alfalfa meal and negatively to chicken manure, and Somycel 3001 reacted positively to rice bran and alfalfa meal at the time of filling (Visscher 1989). Upadhyay and Vijay (1989) also observed cotton seed meal as better supplement for P. fossulatus and rice bran for P. ostreatus. Supplementation is absolutely necessary for getting fructification is some strains of P. eryngii (Royse 1999, Upadhyay and Vijay 1991). With supplementation came a rise in substrate temperature, possibly due to faster metabolic activities riggered by extra nitrogen.Royse and Schisler (1986) also observed overheating (from 300C to 470C) in bags where Spawnmate was applied without benomyl treatment, and proposed that it could be due to the growth of competitor moulds. GurJar and Doshi (1995) did not find any effect on yield of P. cornucopiae with 5 and 7. 5% addition of soybean meal in wheat straw and assumed this could be due to a rise in temperature. We identified increases in the temperature of beds from 5 to 90C over room temperature. Therefore, supplements should be cautiously used, because excessive bed temperature (more than 350C) may kill the mycelium.OverstiJns (1995) observed an increase of 19% in mushrooms with the addition of only 0. 5% corn steep liquor and recorded a rise in temperature from 0. 3, 1. 4 and 2. 30C with the addition of only 0. 5, 1 and 2% corn steep liquor. Higher supplement doses gave even higher temperatures, which were harmful and attracted growth of Coprinus sp (Guna segaran and Graham 1987). In A. bisporus, the addition of formaldehyde-pretreated 1 and 2% cotton seed meal and soybean meal at the time of casing produced 20 and 30% higher yields respectively, but higher doses of supplement attracted a lot of contamination (Gupta and Vijay 1992).Supplementation has also been found to facilitate higher mushroom yield in other mushrooms such as Agrocybe aegerita and L. edodes (Zadrazil 1994, Jong 1989). Higher supplementation (3 to 4% w/w) of NPK in rice husk, melon husk and coconut fruit fibers did not give either mycelium growth or basidiocarp from the tubers of P. tuberregium (Isikhuemhen and Okhuoya 1998). Supplementation with de-oiled soybean and cotton seed cake not only gave higher biological efficiency but the fruit bodies were significantly heavier than in unsupplemented bags.

Why the sale of human organs should be legalized Research Paper

Why the sale of human organs should be legalized - Research Paper Example While societal morals may not allow sales of the organs, the contemporary market promises a price for the organs just like any other commodity in the market. In the US, just like in many parts of the world, sale of organs is permitted. However, this can only be done when one passes away, but not the other way round. Studies show that the number of people on the queue to get life-saving organs (often the kidneys, eyes parts) have been growing steadily over the last two decades, whereas the number of potential organ donors has stayed constant (Woodcock 1-3). While in the US the black-market is experiencing an increase in the sales of body organs; blood donation, which is legal, is also on the increase (Kennedy 34). In fact, donation of blood attracts rewards such as free tickets to an event and free clothes, among other gifts. Opponents of selling organs also underscore the fact that if the free market is allowed, there would be a proliferation of vulnerable groups (such poor people) d ue to market imperfection. This paper supports the argument that the sale of human organs should be legalized. Although many people are waiting for organ transplantation in the US, the supply of organs is limited or even unavailable; hence legalization of selling organs would be importance as it would lead to saving of many lives. For instance, the number of patients in the US, who are waiting for an organ transplant, is bigger than the number of donors by almost four folds (The Voice of Russia 1). As a result, on a daily basis, nearly 18 people pass away as they wait for someone to donate them an organ (The Voice of Russia 1). Therefore, permitting the sale of organs will stimulate supply to meet the ever increasing demand. In the US, those who decide to become organ donors are supposed to have the word ‘organ donor’ marked on their licenses, but the donation is only possible after the eligible donor passes

Transportation by Sea Assignment Example | Topics and Well Written Essays - 3000 words

Transportation by Sea - Assignment Example A busy seaport should therefore be viewed as a powerful yardstick for measuring the development in the region in particular and in the country in general. But, the overall development of a port depends on several factors including that of having the port in a geographically advantageous location. The locational advantage, among other factors, plays a prominent role in the growth prospects of a port as it would naturally make the port accessible to the shipping lines of several countries. Apart from the locational advantage, a port should internally posses certain technical advantages too for efficient handling of port operations. and strictly prefer seaports that would reduce transportation costs and time. Port location is therefore one of the prime determinants of its development. The growth of a port also depends on the depth of water, warehousing facilities and the total area. These requirements, along with the importance of location, should be properly studied for port designing and construction depending on the type, size, number and frequency of vessels that would call at the port, type and volume of cargo that would be handled and needs of the warehousing facilities and terminals. ... agoon, in a deep natural bay or river would naturally attract the attention of shipping lines and develop very fast (Internet, Port Planning, Factors influencing sea port locations). Locational advantage When a port is located in a geographically convenient location joining several shipping routes and providing accessibility to several countries, it undoubtedly attains the geographically locational advantage. Such a superior port conspicuously draws the attention of the shipping lines and attracts huge demand for its services. If the port is also located in a deep water zone, it would facilitate the docking of the bigger ships (Internet, A new port in Shanghai, 20 miles out to sea, Para 9). Because of the innumerable advantages of having deep water ports, several countries, including India, have drawn up big plans in this regard (Internet, Ambitious growth plans for Kakinada deep water port, 3 2001). The main advantage of such a port is that its services are generally useful not only for the country but also for its neighbouring countries. Different countries, operating their shipping lines for the transportation of their different commodities and goods, would crave for utilising the facilities of such a port to meet their growing demands. When the advantageous location is effectively aided by the presence of industrial growth in the region, it adds magnificently to the port development (Internet, The fundamentals of ports management, function and role of an international port). Infrastructure While the locational advantage is the nature's gift for a port and serves as the basic ingredient for its development, the port location should be fortified by the presence of excellent infrastructural facilities to render quality services at reduced costs to various

Commercial law Essay Example | Topics and Well Written Essays - 1750 words - 2

Commercial law - Essay Example Once the terms of an agency agreement have been made, it is important to draft a written contract that any of the parties involved can request, which would state the duration of the contract among other things. An agency agreement usually contains the fixed term of the contract, exists for an indefinite term that is terminable and lastly a fixed term that can be extended if agreed by both parties1. In relation to Rosie and Simon’s case, the parties did have a written contract or agency agreement that did not state the terms of their contract in detail. The implication of this is that it might be difficult for Simon to prove that Rosie went against the terms of the contract that they had agreed upon through the written agency agreement. Additionally, Rosie is in breach of the contract they agreed upon with Simon because she did not give Simon the 10% commission that they had agreed on when he sold a piece of work for her. In order for Simon to be safe, he would have made sure that he drafted a contract that captured much detail on how he was to make money out of the contract. For this reason, Rosie could be entitled to not pay Simon. On the contrary, the Commercial Agents regulation requires that either of the parties wishing to terminate an agreement entered for an indefinite period issue adequate notice to the other party, which Rosie did not comply. The regulation requires that a person provides notice of termination depending on the period they have been in the contract. For example, if they have been in the contract for a year, they should issue a one months’ notice, two years attracts a two months’ notice and so on. Therefore, Simon has grounds to seek compensation for the breaching of the contract that he had entered into with Rosie based on not being issued with proper notice. The regulation requires that a principal act dutifully to the agent and in good faith to which she did not

The substance of this prose assesses the symptoms, background and the intensity of the problem in soldiers and Veterans. This qualitative analysis of the disorder not only defines the perceptions of the disorder but a lso discusses how the sufferer cope with the symptoms and how the symptoms and behavior exhibited by the sufferer may be transmitted in their children, that significantly hampers the child’s functioning. ... The disorder can be triggered in any individual and the most common incidents that can give rise to this problem are rapes, domestic violence or violent death of a loved one; in other words any incident that threatens the psychological or physical integrity of the individual. There are millions of factors that contribute to exacerbating the symptoms experienced by the sufferer; however, there is a significant amount difference between the vulnerability of each individual and factors such as self-efficacy, self-esteem, personality and the social support that an individual has that plays an important role in how the symptoms are exhibited by the individual. Eminent researchers Davidson and Mellor (2001) noted that children of PTSD victims were likely to exhibit the behavior exhibited b y the client and the impact is extremely pervasive They stated, â€Å"Symptoms in their children, including lower self-esteem, higher disorder rates and symptoms resembling those of the traumatized pare nt† (Hunter, 2001, p. 345). Therefore, it can be argued that there is a genetic diathesis involved that regulates the vulnerability of the individual effectively and also shows that the symptoms can have detrimental repercussions on the people around them. Researchers have also discovered that these effects are more pronounced on people who have witnessed combat that is soldiers and veterans. Military services have offered therapies and various programs to help and screen individual to check the impact of the violence that the client experienced on the battlefield. There is a repertoire of symptom that the individual experiences after serving in the army and this is vastly due to the

Ethical Issues for Engineers Working in a Design Engineering Company Essay

Ethical Issues for Engineers Working in a Design Engineering Company - Essay Example In the U.S, the National Society of Professional Engineers offers guidelines on ethics and professional conduct of the engineers. Bribery and corruption are prohibited as well as ethical issues like sustainable development and environmental protection (Baura 13). For instance, the American Society for Civil engineers requires members to observe health and safety and welfare of the society while executing their duties. The society also requires the engineers to reject corruption and bribery and offer services to the best of their competence (Christine Van Gorp 91). In a design company dealing with gas and oil exploration, an engineer may be required to design oil and gas rigs. The engineer will be responsible for developing reservoir simulation codes requiring a lot of computations. The engineer will perform test analysis by applying the principles of physics and mathematics and separation of hydrocarbons (King 33). The engineer may be required to offer advice on hydraulic fracturing systems and offer sufficient advice in the design of the oil and gas rigs (Heidersbach 3). Oil wells and rigs are used to get out from the ground to the surface tankers or pipelines up to the refineries. Oilrigs support structures constructed around the oil wells while the drilling takes place (King 51). The rigs may be on the ground or floating on the sea but are used to drill down to the strata that contain the oil deposits. The pumping system is then used to get the oil to the tankers or the pipelines (Heidersbach 2). The engineer is required to hold paramount health and safety welfare to the public by performing duties only in the areas of competence. The engineer is supposed to conduct himself responsibly and lawfully so as to enhance the reputation of the Company and the engineering profession (Baura 16). If the engineer’s judgment is overruled in cases where it endangers the health and safety of the public, the engineer is supposed to immediately inform the employer or client so that appropriate action may be undertaken. The engineer is supposed to inform the professional body in case of violation of the ethical code of conduct (Baura 16). The engineer is not supposed to make material misrepresentations, omit material facts, or make statements that are geared to deceiving the public on health and safety matters (Gunn and Vesilind 59). According to the ethics code of Institute of Engineers of Ireland, engineers are supposed to promote the principles of sustainable development in order to protect the future generations and the ec osystem (Unesco 184). The members are supposed to ensure the engineering projects have minimal adverse health and safety impact to the environment (Fleddermann 59). The engineer should ensure economical use of the natural resources like water wastage and avoidance of pollution (Unesco 185). The engineer is supposed to promote environmental awareness education among the public in order to promote the welfare of the community by avoiding pollution and natural resource wastage (Unesco 186). Companies in the oil and gas industry may cause adverse effects on the environment. Some of the environmental stressors include noise, fugitive dust, vegetation clearance, drilling waste, accidental oil releases, air pollution, sedimentation, and turbidity from the onshore surface runoff (Harris, Pritchard and Rabins 77). The magnitude

Format your work according to the class writing guide: †¢Genocide is the deliberate and systematic destruction of an ethnic, racial, or national group, such as the Turkish killing of Armenians after WWI, the Nazis’ slaughter of 6 million European Jews during WWII, or the mass killings in Rwanda in 1994. Has genocide ever been practiced or condoned in North America? Explain your response. Yes, genocide has been both practiced and condoned in North America and the United States. The native inhabitants of North America, or Native Americans, were destroyed as a people. In the early 18th century, several states including Massachusetts, Connecticut, and New Jersey promoted the genocide of local native people by offering a scalp bounty on every dead native. In 1703 12 pounds was the price paid per scalp by the State of Massachusetts, by 1723 that price had soared to over 100 pounds per scalp. In that same period, George Washington compared Natives to wolves or beasts of prey, and called for their total destruction. By 1814, Andrew Jackson supervised the mutilation of more than 800 members of the Creek Tribe, which had been murdered by his troops. As time progresses to 1867, General William Tecumseh Sherman was saying, â€Å"We must act with vindictive earnestness against the Sioux [Lakota] even to their extermination; men, women, and children. † No one knows a precise number of Native Americans that were murdered at the behest of our United States Government, but some estimates make the number of European Jews murdered by German Nazis look small. (Religious Tolerance, 2011) †¢Consider the readings from this week as well as last week. What is the difference between Arab Americans and Muslim Americans? Why are the two often thought to be interchangeable? Explain your response. Arab Americans are Americans of Arabic heritage, which have either immigrated to the United States or have been born here and can trace their lineage back to the Middle East. (The Prejudice Institute , 2012) However not all people from the Middle East are Arab. Muslim Americans are people who practice the religion of Islam and live in the United States. (Muslim Americans, 2011) I think that often these two terms are thought to be interchangeable because there are a great deal of Muslims in the Middle East and those are the Muslim Extremist that we she on the news. Therefore, as we always do we go right to the stereotypes that have been played out in the headlines of the news. So if a person is of Arabic decent he or she must also be Muslim, which is why people tend to consider the two terms interchangeable. ? References Religious Tolerance. (2011).

Important and application of data mining

Important and application of data mining Important and application of Data Mining Abstract Today, people in business area gain a lot of profit as it can be increase year by year through consistent approach should be apply accordingly. Thus, performing data mining process can lead to utilize in assist to make decision making process within the organization. This paper elaborate in detail the level of importance and also the application the application of data mining which can be adopt for various fields depends on the objective, mission, goals and purpose of conducting the study within the organization. there are three main areas take as a example which are hotel, library and hotel to observe on how data mining works to these main field. Keywords: Data Mining, KDD Process, Decision Trees, Ant Colony Clustering Algorithm; Association Rules, Neural Network, Rough Set, 1.0 Introduction As we know, organization which conducts business transaction is keeps massive of document or data in a specific database for further retrieval. The data are combine from are a few departments that carried out different task and each of their function parallel with the mission and vision of organization. According (Imberman, 2001) the number of fields in large databases can approach magnitudes of 102 to 103. Therefore, it is necessary to make proper decision making or strategic planning using the existing data where these plays important role in order to ensure any action that are taken place does not given an impact especially bring loss to the organization. Other than that, data became obsolete when it keeps on changing and easily out dated as the user requirement shifting depends on factors such as trends, money, needs and so forth. One way to analyze data is using of data mining technique which enable to assist organization by emphasize several steps to produce the valuable output in short period of time compare with the traditional method which may involves more than one methodologies and it derive to longer of time to accomplish the investigation towards a portion of data. Thus, in the business area an action should be done quickly in order to compete with other competitors and to improve performance both in giving service and produce a high quality product. Moreover, process interpretation of the result involves group of people to inject some of the creativity and synthesis which can lead to the solutions on the problem or tasks. Obviously, data mining a lot assist in various fields with different purposes and depend on the objectives that want to achieve. The rest of this paper is organized as follows. Section 2 tells about definition of data mining. Section 3 determines the importance of data mining. Section 4 explains the application of data mining in various fields. Section 5 draws the conclusions. 2.0 Definition of Data Mining There are abroad definitions listed by a few researcher and academician according to their view and opinion based on the study they have done. Moreover, these will help to understand or giving an idea before discusses more in depth towards data mining technique. Basically, the main purpose use of data mining is to manipulate huge amount of data either existence or store in the databases by determine suitable variables which is contribute to the quality of prediction that will be use to solve problem. Define by Gargano Raggad, 1999. Data mining searches for hidden relationships, patterns, correlations, and interdependencies in large databases that traditional information gathering methods (e.g. report creation, pie and bar graph generation, user querying, decision support systems (DSSs), etc.) might overlook. Besides that, another author also agreed with opinion toward the data mining definition which is to seek hidden pattern, orientation and also trend. Through (Palace, 1996) added to the previous is: Data mining is the process of finding correlations or patterns among dozens of fields in large relational databases. Moreover, data mining also define as process to squeeze of knowledge or information using appropriate framework or model to analyze until produce an output that assist in fulfill the objective of the study. From Imberman, 2001: As knowledge extraction, information discovery, information harvesting, exploratory data analysis, data archeology, data pattern processing, and functional dependency analysis. The statement above agreed and adds that the framework or model that adopt definitely to expose the real circumstance. Define by Ma, Chou Yen, 2000: Data mining is the process of applying artificial intelligence techniques (such as advanced modeling and rule induction) to a large data set in order to determine patterns in the data. In the other hand, data mining is taken a few steps during analysis and this step is depending on the methodology that is chosen. Each of the methodology is not much differ from other methodology. Through Forcht Cochran, 1999: Data mining is an interactive process that involves assembling the data into a format conducive to analysis. Once the data are configured, they must be cleaned by checking for obvious errors or flaws (such as an item that is an extreme outlier) and simply removing them. 3.0 Important of Data Mining As discusses above, it can be seen that data mining will be beneficial a lot of party and multiple range of level in the organization as the model or framework that is apply can reduce time and cost. Then, the results allow the responsible knowledge worker to transform into the strategic value of information effectively by critically analyze the result. The process should be done carefully to avoid the useful variables or algorithm being removes or not be included in the extraction of reliable data. Data mining techniques will help in select a portion of data using appropriate tools to filter outliers and anomalies within the set of data. According to Gargano Raggad, 1999, there are a few others important of data mining consist of:  · To facilitate the explication of previously hidden information includes the capabilities to discover rules, classify, partition, associate and optimize. According to (Goebel Gruenwald, 1999) in order to seek the pattern of data, a few methodologies are use in clarify the vagueness as well as to identifying the relation among one variables and other variables within the databases whereas the outcome will guide in making decision or to forecast the impact when the action were take into consideration. The chosen of methodologies should be determined in a proper way suit with the rules and condition towards the data which is to be analyzed. The methodologies include: Statistical Methods: focused mainly on testing of preconceived hypotheses and on fitting models to data. Case-Based Reasoning (CBR): technology that tries to solve a given problem by making direct use of past experiences and solutions. Neural Networks: formed from large numbers of simulated neurons, connected to each other in a manner similar to brain neurons which enables the network to learn. Decision Trees: each non-terminal node represents a test or decision on the considered data item and can also be interpreted as a special form of a rule set, characterized by their hierarchical organization of rules. Rule Induction: Rules state a statistical correlation between the occurrences of certain attributes in a data item, or between certain data items in a data set. Bayesian Belief Networks: graphical representations of probability distributions derived from co-occurrence counts in the set of data items. Genetic algorithms / Evolutionary Programming: formulate hypotheses about dependencies between variables, in the form of association rules or some other internal formalism. Fuzzy Sets: constitute a powerful approach to deal not only with incomplete, noisy or imprecise data, but may also be helpful in developing uncertain models of the data that provide smarter and smoother performance than traditional systems. Rough Sets: rough sets are a mathematical concept dealing with uncertainty in data and used as a stand-alone solution or combined with other methods such as rule induction, classification, or clustering methods  · The ability to seamlessly automate and embed some of mundane, repetitive, tedious decision steps not requiring continuous human intervention. Several steps are taken in processes or analyzes on selected data where the process involves of filtering, transforming, testing, modeling, visualization and documented the result or store accordingly in the databases or data warehouse. Each of the steps functions differently and has responsibility in carries out the process with the purpose to easier and produce the high quality of assumption by automate generate towards specific conditions. For example, data warehouse also keep previous analysis and this allow eliminating the redundant output at certain steps. Through Ma, Chou Yen, 2000, they stress the characteristics of data mining define how it assist to reach the end process of analyzing. It comprises: Data pattern determination: Data-access languages or data-manipulation languages (DMLs) identify the specific data that users want to pull into the program for processing or display. It also enables users to input query specifications. Therefore, users simply select the desired information from the menus, and the system builds the SQL command automatically. Formatting capability: It generates raw data formats, tabular, spreadsheet form, multidimensional-display and visualization. Content analysis capability: Data mining also has a strong content analysis capability that enables the user to process the specifications written by the end-users. Synthesis capability: Data mining allows data synthesis to be timely executed.  · Simultaneously reducing cost and potential error encountered in the decision making process. Basically, data mining can minimize the error of forecasting by following the steps of selected methodology in well manner to avoid delaying in making decision where this situation will giving big impact for the business area. Therefore, it must be careful in handling the data throughout the steps involves whereby the strategic plan should take into consideration includes of the objectives to done the analysis, the amount of data, the variables, the relationship between variables, test adopted, and so forth. Moreover, if there is need to discuss with the professional towards the study conducted and it should be included in the planning part. In the context of organization, usually a unit or group of people are given responsible to carries this duty to discover the hidden pattern for another department. Hence, the continuously meeting should be done between the professional and researchers to ensure the end result fulfill their requirement as well as to improve the performance of work er, department and organization. In term of reducing a cost, compare to the traditional research which take time in acquiring the data from respondents and it depend on the methodologies that are use and the number of sampling. If the questionnaire method, it can be done quickly and less time consuming but if the interviewing method is adopted, it surely take time and researcher have to meets the respondent more than one time, if there is an ambiguity or the answers not meet with the requirement. For certain study, the sampling are involves from the different location which require the researcher to travel in order to gain the genuine opinion from them and this will cost a lot involves of accommodation, food, flight ticket and so forth. For data mining, it uses the existence of data (for example, data of customer transaction, data of student registration, data of patient undergo the operation process and so on) that keep in data warehouse which mostly reduce cost in aspect of acquiring data. Other than that, researc her take first action by search for the study in the data warehouse when the objective being determine at the beginning of study because previous study are store in the data warehouse. If it is found tally, a few step will be skip or easily decided towards the data and it prove that data mining can reducing the cost as well as time. Refer to Gargano Raggad, 1999, data mining also derive long term benefit which the cost incurred due to the development, implementation, and maintenance of such systems by a wide margin. 4.0 The application of Data Mining Nowadays, data mining is widely use especially to those organization that focuses on consumer orientation. For example, retail, financial, communication, and marketing organizations (Palace, 1996). Besides it, healthcare area also gain benefit by apply the data mining into the daily operations. These various of field shows each of the organization carries different transaction where all of details keep in the databases which enables to perform analysis for multiple purpose likes to increase revenue, gain more customer, improve customer satisfaction and others. Moreover, again through (Palace, 1996) the existence data allow to determine relationships among internal factor consists price, product positioning or staff skills and external factor consists economic indicators, competition and customer demographic. Hence, there three examples of data minings application in different areas which are hotel sector, library scope and also hospital with the goals to reduce or eliminate the weakness by address it using the result that is interpret in well manner to assist in making decision for the best solutions. The examples are as follows:  · A data mining approach to developing the profiles of hotel customers. A study conduct by Min, Min Ahmed Emam, 2002 with the objective to target some of the valued customers for special treatment based on their anticipated future profitability to the hotel. There are a few questions regarding to the customer profiling: Which customers are likely to return to the same hotel as repeat guests? Which customers are at greatest risk of defecting to other competing hotels? Which service attributes are more important to which customers? How to segment the customer population into profitable or unprofitable customers? Which segment of the customers best fits the current service capacities of the hotels? The researchers adopt decision trees for analyzing the data from the abroad method of data mining methodology because the ability to generate appropriate rules using visualization and simplicity. There are three steps having to follows in this process and it includes: Data collection: the process of select data that suit with objective from the previous survey. Moreover, remove the unwanted data from databases by filtering out the excel file. Data formatting: the process of converted all data in the spreadsheet to Statistical Packages for Social Sciences (SPSS) for the purpose of classification accuracy. Rules induction: the process of selection of algorithms to building decision trees which is C5.0 to generate sets of rules that bring important clues in order for hotel manager to take further action. As the result, the researcher found that if-then rules as a useful in formulating a customer retention strategy with a predictive ranging from 80.9 per cent to 93.7 per cent whereas a predictive accuracy reflect to the rules conditions that affect by times (percentage).  · Using data mining technology to provide a recommendation service in the digital library. A study conducted by Chen Chen, 2006 with the purpose to provide recommendation system architecture to promote digital library service in electronic libraries. There are abroad of digital publication format likes audio, video, picture, etc. thus, it lead difficulties in analyzing or defining the keyword and content in order to gain information from the user to improve the service in the digital libraries. In the methodology section, there are two data mining models selected which consist o Ant Colony Clustering Algorithm; This model is capable to find the shortest path or reduce time to find the best output fit with the problem that existence in the organizations. Each of the steps has different function to enable they too see the relation among the variables It takes a few steps which are: Step 0: parameters and initialize pheromone trails. Step 1: Each ant constructs its solution Step 2: Calculate the scores of all solutions Step 3: Update the pheromone trails. Step 4: If the best solution has not been changed after some predefined iterations, terminate the algorithm; otherwise go to step 2. o Association rules to discover the hidden pattern. This model enables to find co-purchase items and assist in uncovered relationship algorithms in form of association rules. There are two main steps as follows: Step 1: Find all large item sets Step 2; use the large items set generated in the first step to generate all the effective association rules. As the results, these two models encounter more than one solutions and enable to gain a lot of recommendation that can be manipulate into various problem that exists in conducting digital libraries as well as to promote the usage in multiple level of user using the appropriate mechanism and providing suitable services.  · Using KDD process to forecast the duration of surgery. A study conducted by Combas, Meskens Vandamme, 2007 with the aim is to identify classes of surgery likely to take different lengths of time according to the patients profile as well as to allow the use of the operating theatre to be better scheduled. There are many issues arise in this field that lead to the study. For example, an endoscopy unit use of endoscopy tube (shared resources) during the surgery. However their availability is limited because it takes 30-45min to clean and sterilize each one. The scheduling of endoscopies (and all other operating theatre procedures) must obviously take into account the availability of these different resources. The researchers adopt Knowledge Discovery in Databases (KDD) process to analyze this massive data from the databases. The step as follows: Step 1: data preparation which the selected data must be fulfill of requirement includes secondary diagnoses, Previous active history and system affected. Step 2: data cleaning where filter data by concerning surgical procedures that had been performed at least 40 times (at least 20 times for combinations involving both surgery and specific surgeons). Step 3: data mining which to decide appropriate method to test on the portion of data which it involves rough set and neural network. Step 4: validation by comparison consist process of interpretation by comparing the result from two methods that perform data analysis in order to observe the rate of good classification. Then, researcher added up another three steps in order to fit with the objective that is proposed and to produce the best outcomes to forecast the durations of surgery. It consists of: o Step 5: Measuring the impact of predicting the duration of surgery on planning which in this step the duration of surgery supplied by the prediction models (empirical laws, rule-based laws, etc.) based on information stored in the database is used to feed a series of algorithms and heuristics for planning purposes o Step 6: Simulation involves the present time will allow to simulate the activity of the different theatre suites in terms of the operating sequence determined by planning methods on the two scenarios which are operating data and patients profile o Step 7: validation selection of the best model where the results supplied by the simulation model should enable to assess the quality of scheduling on the basis of a series of performance indicators likes the length of time for which the operating theatres are not in use, the number of potential additional hours, and errors in predicting the duration of surgery. As the results, researchers are not particularly satisfactory. The main problem seems to be the choice of variable grouping, which might possibly have an effect on prediction quality. 5.0 Conclusion As a conclusion, data mining can be consider as an effective and efficient way to discover or to transform the invisible to visible data that retrieve from databases which have capabilities to store huge amount of data by using the right tools in assist or enable to analyze, synthesis and manipulate the content of data for various purposes and often depend on the main businesses that carries out to define the target. From the discussion above, it can be seen that there are a lot of advantages when perform data mining especially in the business area which allow the organization to predict the trends, customer requirement, the relationship and so forth as early preparation can be identify in order to seek another or a few others way to ensure that organization can still operate their daily operation after determine that organization not agree towards the result have been gain. In order to produce the end result that satisfying the organization and minimize the error as it successfully implement the information in order to perform business transaction. The key variables should be assign in well manner meet or suitable with the objective that propose in conducting the study because it have to repeat the procedures when found the errors as the decision making process could not been done according to the timeline. 6.0 References Chen, Chia-Chen Chen, An-Pin.

Background Of Apple Inc Commerce Essay

Background Of Apple Inc Commerce Essay Apple Inc. is a company that designs, manufactures and markets mobile communication and media devices, personal computers, and portable digital music players. Apple Inc. also sells a variety of related software, services, peripherals, networking solutions, third-party digital content and applications. The company sells products and services such as iPhone , iPad , Mac , iPod , Apple TV , a portfolio of consumer and professional software applications, the iOS and Mac OS X operating systems, iCloud , and a variety of accessory, service and support offerings. Furthermore, the company also sells and delivers digital content and applications through online stores the iTunes Store, App Store, iBookstore, and Mac App Store. The company sells its products globally through its retail stores, online stores, direct sales force, through third-party cellular network carriers, wholesalers, retailers, and value-added resellers. Not only that, the company sells a variety of third-party iPhone, iPad, Mac and iPod compatible products. The companys target market is end user consumers, small and mid-sized businesses (SMB), and education, enterprise and government customers. Steve Jobs, Ron Wayne and Steve Wozniak were the founder of Apple Inc. In 1976, they invented the first Apple computer which consists of not only circuit board with costs under $700 in Palo Alto, California. They improved the first Apple computer by adding one-megahertz processor and named Apple II became first mass-produced computer in year 1977.Apple officially became a public traded company in 1980. Apple Inc. continued developing a better computer in later years and the first personal computer with feature which has a mouse for navigating and desktop icons and folders called Lisa but this product unable to stay in the market due to high cost of production. On 2007, Apple had kicked off the era of the touch screen smartphone with the invention of first iPhone. This innovation has made a huge change in the smartphone market because it caught the attention of the consumers. On 2010, again Apple unveiled the iPad tablet computer and Apple has passed Microsoft as the largest US technology company in term of market value in May. On 2011, the co-founder Steve Jobs announced his resignation as Chief executive Officer of Apple due to health problem and the Chief Operating Officer, Timothy D. Cook took over his place as the new Chief Executive Officer of Apple. In 2012 September, Apple has introduced its new iPhone 5 which is the lighter, thinner and more powerful of its mobile devices. This new product captured the attention of the whole world by getting a pre-order of 2 million and it is twice than the previous iPhone 4S. Planning Apple is committed to to bring the best personal computing experience to different groups of people like students educators, creative professionals and consumers around the world through its innovative hardware, software and Internet offering.Retrieved from Apple, 2009 Annual Report. Apple Inc. is in a competitive and fast-paced business environment. Everything might change even in the next second. Therefore, it is important for Apple Inc. to be ahead of its competitors. In order to provide the best technology experience to customers, employees are given the freedom to improve products if they found any issues after they used product. Employees do not need to go under procedures that will consume a lot of times. The issues of the product might be the weakness of the company if it is not improve or solve. Apple Inc. plan to build brand loyalty in customers. The mission in Apple Store is to educate and build loyalty in customers. Apple Inc. believed that educates customers are important to build customer loyalty. Therefore, free workshops are offered to people with different level of experience to know more about their new Apple products. Basics of Apples product can be learnt in the workshop. Experiences are shared by those who really understand Apple products to the attendees of the workshop. A One-to-one training program is also offered to customers who have bought a new Mac. In the program, there are three types of training choices, which are personal training, group training and open training. If customers are having a technical problem of their Apple products, they may seek help from Genius Bar where geniuses are available there. The expertise of the geniuses can help customers to troubleshoot the problem of their Apple products. In 1990s, Apple Inc. began to concern about the environment. Efforts are made to minimize the impact of Apple products have on the environment. Chemicals were phased out in producing Apples products. Apple Inc. came out with mercury-free backlit display of Macbook Pro, bromine-free printed circuit board laminates, and more. In 2002, Apple Inc. achieved a recycling rate of 41.9% based on the percentage of weight from the 2002 sales. The introduction of Apple Battery Charger can help reduce the battery waste by 78%. Apple has introduced many application programmes like iTunes, Apps Store, iCloud, iBookstore, Newsstand and more. The introduction of these application programmes had reduced the traditional usage of CDs, DVDs as storage devices for multimedia; Papers for production of literary works. Apple Inc. does not play featured games with its competitors. Instead, Apple Inc. is more focused on its own business than its competitors. For the engineers of Apple Inc., their mission is to come out with great innovative products. The engineers of Apple Inc. are driven to innovation. They are encouraged to come out with products that can challenge the status quo. Organizing Apple Executive Team The organizational chart above clearly showed that Apple Inc. is a functional organizational structure which grouping employees by similar or related occupational specialties. Group employees by similar specialties can make them comfortable and satisfied because it gives them the opportunity to speak in the same language as their peers. The organizational chart also showed that all of the senior vice presidents are directly reporting to the CEO of the company, Tim Cook, because of the wide span of control of the company. Apple Inc. is operating under organic organization structure that has highly adaptive, loose and flexible, which allows company to change rapidly as required. Employees in the company own the freedom to go in and improve the product if they found an issue that bothered them by without having to deal with layers of bureaucracy to get approval. This freedom can make Apple Inc. responds quickly to problems and improves their products faster. On the other hand, if businesses managed their money as carelessly as they manage their people, most would be bankrupt. Recently, Apple Inc. has provided training program for the new hiring employees to improve their ability to perform on the job, thus, training can change employees certain skills, knowledge, attitudes or behavior. After this training, the company can easily put the right people into the right jobs to avoid waste both human and financial capital. Since there is no longer ecosystem to support manufacturing in United States, Apple Inc. decided to manufacture its products in China and cooperate with the worlds largest maker of electronic components, Foxconn. The main reason of Apple Inc. manufactures products in China is the efficiency but not about the cost. Chinas workforce is much hungrier and more frugal compare with United States. Foxconn can recruit 3000 of workers overnight and China also provides engineers to set up the assembly lines in order to expand the production of iPhone. Furthermore, Apple Inc. does not allow the use of underage labor. Suppliers of the company must follow the minimum age for employment in that country, or the age of completing compulsory education in that particular country. The company will require suppliers to return underage labors to school and pay for the educational expenses, living allowances, and lost wages for 6 months or until the labor reaches 16 years old if the company found out that suppliers use underage labor. Leading Steve Jobs, the co-founder of Apple Inc. and the Chief Executive Officer of Apple Inc. before 24 August 2011. He graduated from Homestead High in Cupertino, California in 1972.After that, he attended Reed College but he just studied for one semester and he was dropped out. In 1976, Steve Jobs, Steve Wozniak and Ronald Wayne founded Apple. In 1985, Steve Jobs got kicked out of Apple Inc. by John Sculley. In 1997, Steve Jobs has returned to Apple Inc. and started to lead the Apple Inc. The first task was to make the Apple Inc. more focus on what product should be produced. He told all his team members to focus on four great products, one for each quadrant. By getting Apple Inc. focus on just making four computers, he saved the Apple Inc. He said that Deciding what not to do is as important as deciding what to do. He is also cut down all the unnecessary products, services, marketing, packaging and more. On the last day of each year, he will stand in front whiteboard and ask What are the ten things should be doing next? He likes to hear what is the employees idea on the Apple Inc products, so that they can create more new products to the market. Next, Steve Jobs always warn the employees to simplify the device and software because the first marketing brochure of Apple Inc. declared that simplicity is the ultimate sophistication. This simplification can create competitive advantages among the competitors because the competitors products are much more complicated to use. Steve Jobs simplicity came not by ignoring complexity but rather by conquering it. On the innovation, Steve Jobs did not merely to catch up the competitors but is to leapfrog over them. For example, Steve Jobs was mortified when he found that the slot drive of his iMac could not burn CDs. When facing this problem, Steve Jobs has come out a solution which is create the iTunes store and iPod to reinventing access to music. On 24 August 2011, Steve Jobs has left his position as Chief Executive Officer due to the health problem he faced and his position was took over by Timothy D. Cook who was the Chief Operating Officer of Apple Inc. Now, Timothy D. Cook is the Chief Executive Officer of Apple Inc. He studied MBA in Duke University, and he was also a Fuqua scholar and Bachelor of Science Degree in Industrial Engineering from Auburn University. Today, Apple Inc. has almost 73,000 employees is under the leadership of Timothy D. Cook. Since he took over Apple Inc., Tim Cook successfully steered the company through controversies at Foxconn factories overseas and the success of release the iPhone 5 and iPad mini. The iPhone 5 was released on 21 September 2012 and it achieved pre-order of 2 million over 24 hours and it was double the 1 million the iPhone 4S. Besides, Tim Cook has used his leadership style to change the company environment. For example, the Apple Inc become more corporate, putting more focus on operational efficiency while still striving to maintain the unique culture Steve Jobs forged as the Chief Executive Officer. Timothy D. Cook is much more approachable compare to Steve Jobs. He has no problem to meet with the investors and sometimes he will have meal with his employees which is rarely did by Steve Jobs. Controlling In controlling, the task of manager is to monitoring performance, evaluate how well the organization has achieved its goals and to take corrective actions as needed to maintain or improve performance. The ex-CEO of Apple Inc., Steve Jobs monitors the performance of Tim Cook, the ex-COO of Apple Inc. when he was still around. In Steve Jobss resignation letter, he has named Tim Cook as the next CEO of Apple Inc. This backup plan makes Apple Inc. able to cope with uncertainty. To the Apple Board of Directors and the Apple Community: I have always said if there ever came a day when I could no longer meet my duties and expectations as Apples CEO, I would be the first to let you know. Unfortunately, that day has come. I hereby resign as CEO of Apple. I would like to serve, if the Board sees fit, as Chairman of the Board, director and Apple employee. As far as my successor goes, I strongly recommend that we execute our succession plan and name Tim Cook as CEO of Apple. I believe Apples  brightest  and most innovative days are ahead of it. And I look forward to watching and contributing to its success in a new role. I have made some of the best friends of my life at Apple, and I thank you all for the many years of being able to work alongside you. Steve Retrieved from http://www.apple.com/pr/library/2011/08/24Letter-from-Steve-Jobs.html After the death of Steve Jobs, Apple Inc. hasnt release anything big and new. But it has built better iPhones and iPads. Apple Inc. announced that pre-order of its iPhone 5 topped 2 million in just 24 hours, and iPads sold 3 billion in 3 days. The quarterly profit of Apple Inc. climbed to $8.2 billion on revenue that rose to $36 billion on the backs of hot-selling iPhones and iPads. Within one year, Apple Inc. share increased and the companys value has almost doubled since Steve Jobs death. Apple Inc. manufacturers continually improve electronic technology so that company can offer more power in a smaller package. Apple continually offers smaller devices to the market before the competition. Macbook Air, the thinnest laptop on the market is the prime example of the product in the market. This idea introduced by Apple introduced idea before their competition, so they able to accomplish these feats in record time with streamline workflow processes and automation. Apple Inc. recently came out with Apple Supplier Responsibility 2012 Progress Report that details their effort to improve workers protection and factory condition. Apple Inc does not allow the use of underage labor, if workers had either left or reached legal working age by time of the audit, they will take immediate corrective action. On 28th September, 2012, the CEO of Apple Inc. Tim Cook has written an apologize letter on Apples website regarding with the Maps drama that been unfolding with the introduction of iOS 6. To our customers, At Apple, we strive to make world-class products that deliver the best experience possible to our customers. With the launch of our new Maps last week, we fell short on this commitment. We are extremely sorry for the frustration this has caused our customers and we are doing everything we can to make Maps better. We launched Maps initially with the first version of iOS. As time progressed, we wanted to provide our customers with even better Maps including features such as turn-by-turn directions, voice integration, Flyover and vector-based maps. In order to do this, we had to create a new version of Maps from the ground up. There are already more than 100 million iOS devices using the new Apple Maps, with more and more joining us every day. In just over a week, iOS users with the new Maps have already searched for nearly half a billion locations. The more our customers use our Maps the better it will get and we greatly appreciate all of the feedback we have received from you. While were improving Maps, you can try alternatives by downloading map apps from the  App Store  like Bing, MapQuest and Waze, or use Google or Nokia maps by going to their websites and  creating an icon  on your home screen to their web app. Everything we do at Apple is aimed at making our products the best in the world. We know that you expect that from us, and we will keep working non-stop until Maps lives up to the same incredibly high standard. Tim Cook Apples CEO Retrieved from http://www.apple.com/letter-from-tim-cook-on-maps/ What make Apple Inc. success? Apple Inc. leads the market by introducing the first iPhone. Apple Inc. is growing day by day under the leading of Steve Jobs. Steve Jobss leading style that emphasizes perfection had produced iPhone series that is widely accepted by all market segment. Steve Jobs knew well about technology, market and art so he combined all together when thinking of new product. Engineers in Apple Inc. considered on the quality of the product rather only generates profit. Unlike other competitors, Apple Inc. does not simply come out with a product that is incomplete or dissatisfied. For example, competitors such as Samsung often come out with new products however its products always have problem. Apple Inc. concerns on environmental issue not only save the production costs while also build good image of corporate. Apple Inc. provides variety sources for consumers to solve their problem when they face any problem with the products. Free workshop and Genius Bar where geniuses can help customers to tro ubleshoot the problem of their Apple products. This will help consumers to understand better and know more advantages of Apples product. Challenges Apple Inc. faces challenge in Tim Cooks leadership. Since the way Tim Cook leads is different from Steve Jobs therefore employees need time to cope up with the new leading style. Steve Jobs emphasized perfect in production of products therefore employees are given pressure to maximize the perfection however Tim Cook is more flexible. This might cause the quality of Apples product to decrease. Technology is also a challenge for Apple Inc. Technology improvement is an uncertainty, no one will know when theres new technology will be invented. Apple Inc.s product is based on technology therefore if theres no technology advancement, Apple Inc. will not able to produce new product. Competitors are one of the major challenges faced by Apple Inc. Google new invention of operating system called Android had threatened Apple Inc.s iPhone Operating System. This is because Android can be used in various smartphones such as Samsung, HTC and Sony Ericsson but iOS can only be used in Apple Inc.s products. Android system and iOS system is quite similar, consumers whose purchasing power is low will choose to purchase other products this will eventually affect Apple Inc.s sales. Critique of Apple Inc. If you fail to plan then you plan to fail. Planning plays an important role in every organization and same goes to Apple Inc. The company gives employees the freedom to improve the product if they found any issues after they used product without approval needed. Planning has to accomplish with the companys mission. Apple Inc.s mission is to educate and build loyalty in customers. To achieve their mission, Apple Inc. conducts free workshops to people with different level of experience to know more about their new Apple products. Customers can learn basics of Mac, iPod, iPad or iPhone in the workshop. This will help to build customer loyalty however will consume a lot of time and might not work. Time is precious to the people nowadays therefore will people spend time to attend the free workshop? This is should be considered. Apple Inc. will not able to build customer loyalty if customers do not attend the workshop. Apple Inc. focuses on its own business rather than its competitors; thi s will help them produce a better product but too focus on its own business will cause them unable to compete with its competitors. Technology will improve day by day, if Apple Inc. only focuses on its business, the companys position as market leader will be taken by other competitors such as Samsung. Apple Inc. practices organic organization structure which will let the company to run more effectively. Employees are given freedom to improve the products when they found out any problem of the product, this will help the company to solve the products weakness faster. Yet this may also brings negative impact on company. Improvement done by employees does not require approval from top management, if the changes done by employees had made the product worst this will destroy companys reputation. For example, changes made on one of the apps had clash with another apps and cause the products certain function unable to function.
