Management Principles - Essay Example All managers are accountable for performing the four management functions namely, planning, organizing, leading and controlling work (Schermerhorn, 16). While planning involves objective and goal setting as well as designing methods or procedures to achieve the goals, organizing functions involve arranging tasks, people and other resources to achieve these goals. In order to achieve goals through people and by the use of available resources, managers must be able to effectively inspire their workforce in the right manner. All activities performed by the workforce need to be constantly monitored in order to ensure the tasks are being performed in the right manner. Moreover, managers need to monitor other resources for optimum output and for achieving the targeted performance. These core functions require specific skills and competencies, which managers need to learn by adopting specific behaviors and learning skills related to technical, human and interpersonal, concept and analytic a spects (Schermerhorn, 21-23). Management is greatly influenced by a variety of external and internal factors. External environmental factors that can impact organizational processes include competition, innovative products/services, governmental regulations etc.

Key Success Factors Essay Number of Rivals Wal-Mart’s primary competitors were Kmart and Target. Wal-Mart also competed against category retailers like Best Buy and Circuit City in electronics, Toy â€Å"R† Us in toys, Kohl’s and Goody’s in apparel; and Bed, Bath, and Beyond in household goods. It also competed against warehouse club segment like Costco Wholesale, Sam’s Clubs and BJ’s Wholesale Club. Internationally, Wal-Mart‘s biggest competitor was Carrefour. Scope of RivalryWal-Mart operates nationally, but its principal interests are in the urban centers of United States. Internationally, its interests are mainly in Mexico, Japan, United Kingdom, Brazil, Canada and China. Number of BuyersAs a discounted retailer, Wal-Mart’s customer base is the consumer making individual purchases, and is therefore fragmented and with no appreciable power. Degree of Product DifferentiationThe product is wide product selection and a mix of both name-brand and private-label merchandise, and therefore, a commodity with some minor differentiation available on price, selection and quality. However, Wal-Mart had successfully pursued a low-cost leadership strategy which could provide everyday low prices for their customers Product InnovationWal-Mart provides multiple store formats to attract and satisfy customers’ needs: Wal-Mart discount stores, Supercenters, Neighborhood Markets, and Sam’s Clubs. Wal-Mart should expect it to become a common feature as rivals attempt to copy their success. Supply/Demand ConditionsWal-Mart was the biggest customer of virtually all of its 66,000 suppliers. It allowed it to bargain power with suppliers and get their bottom prices. In 1992 Wal-Mart began establishing standards for its suppliers. Pace of Technological ChangeMore sophisticated means of managing the supply chain, to include EPC/RFID systems mentioned in the case, suggest that new means of reducing costs are presenting opportunities for retailers to obtain an advantage over one another. Vertical IntegrationThe presence of suppliers indicates that the industry is not perfectly integrated. However, Wal-Mart and its competitor each maintain extensive warehousing and transportation assets, suggesting that there is a considerable degree of integration in the industry. Economies of ScaleGiven that the product is a commodity provided by suppliers, economies of scale would be essential in this industry.

The Economic Globalization

The Economic Globalization The economic globalization in terms of international trade, foreign direct investment (FDI) and outsourcing has gained more significance these days due to market liberalization and technological improvement. In this essay, we reveal on the possible effect of economic globalization on Nestle. The emphasis is on whether Nestls internationalization strategy fit in to the observation that we are living in a globalize world in which differences and distances across countries no longer matter. Introduction: The company that we chose for our assignment is Nestle which is one of the worlds biggest global food and nutrition corporations; it has more than five hundred factories in more than eighty countries, and vends its products in more than hundred and ninety nations. Nestle is one of the oldest multinational corporation which was originated in 1866 in Switzerland by Heinrich Nestle. The Nestle firm from its very initial days, looked to different countries for development opportunities and Nestle started its global business by setting up its foremost foreign offices in London in 1868. The Nestle got merged in 1905 with Anglo Swiss Milk Corporation to extend the companys product line and by the late 1990s the Nestle Company had more than five hundred factories in different countries almost operating its business in each country of the globe. There are certain corporate business principles that Nestle follow in all the countries in which it operates its business activities, taking into account local legislations, cultural and religious practices of each country. These principles are: 1. Nestls basic intend is to enhance the quality of consumers everyday lives by offering tastier, healthier and hygienic food and beverage choices that encourages a healthy lifestyle. 2. Secondly Nestle gives quality assurance and product safety all over in the world as well as the company name Nestle basically symbolizes a guarantee to the consumer that the product is harmless and high of standards. 3. Nestle also make sure that they are committed to accountable and trustworthy consumer communication that gives power to consumers to use their rights and give any kind of feedback about their products. 4. Nestle also feels that they are highly committed to do their business practices in such a way that are environmentally sustainable like at all phases of the product life cycle they make sure that they use natural resources efficiently. 5. Last but not the least Nestle is highly committed to the sustainable use of water and tries to improve constantly in water management as the whole world facing a mounting challenges of water and for this Nestle convey messages to all people to use water as a complete necessity. The word globalization usually refers to the opening of international borders to trade, information and technology and the foreign direct investment (FDI). Globalization has caused remarkable changes to the business practices around the world. Nestle outsource professionals from different parts of the globe, causing job shifts and changes in company structures. Nestle believes that expanding business internationally guides to voluntary exchange of capital and employees as well as goods and services, which in turn provides overall universal growth. On the other hand the detractors of globalization argue that more might be done to help out people in poor countries attain the living standards of those in richer countries. Nestle follows a decentralization and all the responsibilities of operating decisions is pressed down to local units, which typically enjoy a high extent of independence with regard to decisions relating to pricing, distribution, marketing, human resource etc. Nestle can be called as a regional organization because the company divides the globe into five major geographical zones Europe, North America and Asia that are responsible to develop regional strategies, as Nestle operates in more than eighty countries it is a wise decision of dividing a globe into geographical zones so every zone would easily look after that every country follows developed regional strategies and maintain same quality standards throughout the world. There are certain effects of foreign direct investment (FDI) on the home country of the company. Within the host countries multinational firms like Nestle almost always pay higher salaries than the locally owned firms the main reason behind this is their presence usually increase the pay level in the host countries. These multinationals usually have higher productivity than local firms. The major role of FDI is to support the growth of host country exports and associations to outside the world and also the conversion of host economies from being exporters of food to relative high technology manufacturers. Nestls impact of FDI is the great knowledge of world markets and of different ways of fitting into international production networks. Technology: A multinational company like Nestle can attain technology infrastructure investments, along with improved business aptitude and good control over worldwide operations with a single global instance of its activity resource planning system, but the essential combination of databases and application servers can be technically and managerially difficult. Nestle uses web based technology to administer worldwide transportation. The Nestle Research Center is the focus of global research area, internally, with best scientists from all over the world and outwardly, in collaborations with key international research universities. The basic role of Nestle Research Center is essential in helping the company to fulfill its vision of GOOD FOOD FOR GOOD LIFE. The entire network of Research and Development and the Nestle Research Center carry out timely research on nutrition, health and wellness issues, and therefore using research findings to produce new product ideas keeping in mind consumer health and wellness needs. The research ideas from Nestle Research Center are transformed into product applications and processes through Nestls international network of Product Technology Centers and Research and Development. The Product and Technology Center exist for each specific product category that includes Dairy, Beverages, Chocolate and Coffee, Biscuits, Ice cream, Pet care and food services. The Product Technology Centers also gives plan for product innovation and packaging. The global network of Product Technology Centers and Research and Development works closely with Nestle Research Center as well as with nestle Strategic Business Units to provide scientific support for the entire nestle product range and the outcome is the Nestle products are tasty, healthy, conveniently available. Nestle believes that the Nestle Research center is a basis of Nestls international success in promising safe and high quality products. With the advance technologies and scientific expertise Nestle carefully analyze their raw materials and finished products and assure that they provide safe and healthy product to all consumers in every part of the world and also believes that it is their responsibility to protect consumers and maintain their trust in Nestls products and brand. It is important for any company to upgrade its technology time to time to maintain a competitive within in the industry. Nestle just in five years from nineteen ninety four to nineteen ninety nine spent approximately five hundred and seventy five million dollars to seven hundred and fifty million dollars a year on its information system. These costs were mounting when the company was facing a loss. Geography and Distance: As a multinational company Nestle operates in more than eighty countries with more than two hundred and sixty five thousand employees. Although Nestle is a Swiss company but generates only two percent or even less than two percent of their sales in Switzerland which is a home country of Nestle. Nestle always believes in decentralization and also believes that it is beneficial for any company to think globally and act locally. The people of Nestle believe that in spite of globalization the food business remains a local business which is based on local cultures, tastes and habits. This thinking of Nestle helped a lot in making a Nestle so renowned and successful all over the world. Therefore well get a different taste of Nestle products in each of the countries where Nestle sell its products. Nestle may be recognized for its chocolates, coffee, pure water, milk and infant formula, but it is a lot more multifaceted and large than that, it is the worlds biggest food company with almost seventy billion dollars in annual sales. Nestle operates five hundred factories in some two hundred nations including those places as well that are not part of the United Nations yet. Nestle earn more sales by selling small items like Kit Kat chocolate which is the largest selling chocolate bar internationally. As we have just described above that every country has its own tastes and habits so for Nestle nothing is simple as it operates in more than eighty countries. The coffee Nescafe which is a global brand and more than hundred billion cups of it consumed each year in different countries and for just one product Nescafe the Nestle Company has two hundred formulations, to go with local tastes. In all the Nestle corporation produces almost hundred and twenty seven thousand different varieties and ranges of products. Brabeck , a chief executive officer (CEO) of Nestle since nineteen ninety seven, wanted to maintain some discipline in terms of how the company is operating the businesses throughout the world that sustain marketing of its enormous range of brands, products and factories. For Nestle operating business maintain same quality standards in so many different countries with enormous range of products is very difficult and also to keep control of its thousand of supply chains with respect to each country and each product variety, along with that predicting demand for different products in different countries and the uncountable different of ways of charging customers and collecting payments is more difficult. Home and Foreign Government Policies: Administration control is a serious issue for multinational corporations that operate in international markets (Geringer and Hebert, 1989; Groot and Merchant, 2000). On hand indication suggest that multinational firms like Nestle transfers their managerial practices from their country of origin which is also called home country to the country of operations which can be called a host country (Child et al, 2000). Firms operating in more than one country like Nestle go through pressures to incorporate their international business. Nestle incorporate their business internationally through methods of standardization that could attain either on the basis of home practices or any best global practices. The degree to which the host country affects multinationals like Nestle depends on two factors the first one is the institutional distance between the home country and the host country. The more the institutional difference among the host and the home country the easier it is to identify the host country effect. Secondly the power of national institutional law is important. Nestle or any other multinational corporations are under more pressure to meet the terms in more strongly regulated business systems than in weaker institutional system environments. There are certain government incentives as well like economic, financing and other incentives that play an important role in attracting multinational investments. These government incentive policies are usually joint with performance necessities, for instance increase in exports, technology advancement, innovation enhancement and environmental friendliness. If multinational corporations investments meet all these government necessities they would be able to get special treatment. Conclusion: As Nestle is a principle based company it believes that by creating shared value is how they do business, which states that in order to create long term value and maintain a good relationship with consumers they have to create value for society. All the strategies that Nestle follows from product development to the delivery of products to their consumers clarifies that we are living in a globalize word in which differences across the countries no longer matter. If we talk about the products that Nestle offers like chocolate, coffee, biscuits, drinking water, and milk etc, everybody in the whole world consume all of these products. So if everybody is consuming same kind of products with just little differences in terms of taste verifies that we are living in a globalize world where the distances and differences no longer matter. Nestle is one the most successful company who caters more than 192 nations of the world and maintains the same quality standards of its brands and products th roughout the world.

Analysis of Pearl Harbor the Movie Essay -- Jerry Bruckheimer Film

Pearl Harbor The movie Pearl Harbor directed and produced by Jerry Bruckheimer was released in 2001. This highly praised movie allows the audience to carefully watch a movie that is based on a day that started the United States' involvement in World War II. The movie begins with a two boys, Danny Walker and Rafe McCawley, who have grown up hoping to become involved in the United States military and slowly changes to the life, excitement, and hardships of being involved in the war. Rafe is one of the best fighter pilots in the regiment and falls in love with a beautiful nurse, Lt. Evelyn Johnson. As the United States tries to help the British, Rafe volunteers to go to London. After several months he supposedly dies when shot down by a German aircraft. This devastating news is told to Lt. Evelyn Johnson by Danny Walker who is still trying to deal with the situation. A few months went by and Lt. Evelyn Johnson and Danny Walker fall in love. Being alone during a time of war was not an idea l situation, one that all military men and women hated. They found themselves to be compatible and in love. They enjoyed their relationship together until news is delivered to Danny that Rafe is still alive. During all this time United States avoids involvement would in the war because they felt that their involvement would not have an impact. The relationship with Danny and Evelyn progresses and so did the war. It is on December 7, 1941 when the Japanese attacked Pearl Harbor. In the movie Pearl Harbor, Bruckheimer attempts to describe what happened on Sunday December 7, 1941 as accurately as possible. However, no matter how hard Bruckheimer tries to present this event historically it will be unclear because it is used primarily ... ...roximity, and pre-judgments. Why did he/she create the movie or book? Where did he/she find his/her resources? How did he/she gain his/her knowledge? However once a person learns how to analyze this they will be able to become more objective when thinking about history. Bibliography Arthur, Max. Forgotten Voices of World War II.

Embedding and Extracting of Secret Data

BLOCK DIAGRAM 3.1 TRANSMITTER Section In Transmitter subdivision there are 3 parts: com/aaimagestore/essays/1863648.001.png"/> Figure 1 The block diagram Transmitter subdivision In Transmitter subdivision there are 3 parts:Input screen ImagesEncoder subdivisionOutput Stego ImageThe screen image used for the proposed strategy to be taken as an input Original screen Image which is used for implanting secret informations in it. Encoder unit is composed of Generation map and secret keys. Encoder determines whether it is smooth country or edged country depending upon the threshold value. In smooth country little figure of spots implanting compared to inch country. Finally at the sender subdivision Stego image is generated which is a combination of secret keys and screen images. 3.2 RECEIVER Section Figure 2 The block diagram Receiver subdivision In Receiver subdivision there are 3 parts:Input Stego ImagesDecoder subdivisionOutput Cover ImageThe Stego Image is taken as an input to the receiver side. The Stego image is decoded right by utilizing secret keys and coevals map to obtain the screen image. The secret keys used in both the sender and receiver side are same. Pixels in the border countries are embedded by Q-bit of secret informations with a larger value of Q than that of pels placed in smooth countries. Chapter 4 PROJECT METHODOLOGY 4.1The proposed adaptative strategy There are five secret keys viz. R1, R2, v1, v2, T and 1 6 v1, 1 6 v2, ( v1 + v2 ) & lt ; 6. The mean different values of a four-pixel block are utilized to sort the block as a smooth country or an edge country. The scope of mean different value is partitioned into two different degrees, smooth degree and border degree. Q-bit of the secret information is embedded in Pixels located in the block, where Q is decided by the degree in which the norm different values belong to. In the implanting procedure of secret informations, harmonizing to the secret keys v1 and v2, the smooth degree will utilize lower value v1 while the border degree uses greater value v1 + v2. The information embedding procedure is given in Section 2.1.1 and the extracting stage is described in Section 2.1.2. 2.1.1. The implanting stage in proposed adaptative method The original image is separated into non- overlapping four-pixel blocks. For each block, there are four neighboring pels ‘Pi, j’ ; ‘Pi, j+1’ ; ‘Pi+1, j’ ; ’ Pi+1, j+1’ and their corresponding grey values are y0, y1, y2, y3, severally. The undermentioned flow chart shows elaborate working of implanting stage in proposed adaptative strategy The elaborate embedding stairss are as follows. Measure 1: Generate Two sets Kr and Kc utilizing threshold Hr ( R1, v1 ) and Hc ( R2, v2 ) , severally. Via sets Kr and Kc form a discrepancy of a Cartesian merchandise viz. , Kr _ Kc. Set Kr _ Kc generates an ordered set of combinations of Kr and Kc with 2v1 †¢ 2v2 = 2v1+v2 elements ( Eq. ( 1 ) ) . Kr*Kc = { Kria†Ã¢â‚¬Å¡a†Ã¢â‚¬Å¡Kcja†Ã¢â‚¬Å¡ , Kri ˆ Kr, Kcj ˆ Kc, i=1,2,3†¦ .} =1, 2, 3†¦ ...†¦ ( 1 ) Measure 2: Calculate the mean difference value D, Which is determined by †¦ . ( 2 ) Where ymin is ymin=min { y0, y1, y2, y3 } Measure 3: Using Threshold T and D find smooth block, Edge block and mistake block. i.e. a ) If D & lt ; =T, D belongs to Smooth block. B ) If D & gt ; T, D belongs to Edge block. degree Celsius ) If D & lt ; =T and ( ymax- ymin ) & gt ; 2*T+2, D belongs to Error block. Measure 4: Repeat measure 3 for full image Measure 5: Capacity= ( ( border block* ( v1+v2 ) ) + smooth block*v1 ) ) *4 Measure 6: For smooth block obtain I utilizing Kr & A ; Secret informations and find‘d’ . For border block: – d=? ( i-1 ) +j†¦ . ( 3 ) For smooth block: – d= I†¦ .. ( 4 ) Measure 7: Create pel group utilizing ‘n=2^Q’ . degree Fahrenheit ( Lolo ) =yi mod n+1 †¦ . ( 5 ) Measure 8: Using pel group embed the Secrets spots Measure 9: If No Of Secret Data=Capacity, travel to step 10 else measure 6. Measure 10: Apply mistake cut downing process for minimising perceptual deformation between screen & A ; stego image. Example: – Assume we have a block part with 4 neighboring pel values ( 210, 237, 198, and 183 ) , and the secret information informations for implanting in original image are ‘10010101110000111010’ . Suppose v1 = 2, v2 = 3, R1 = 257, R2 = 36 and T = 25. Here first coevals map Kr= { 000,100,010,011,001,110,101,111 } is created by utilizing Hr ( R1, V1 ) i.e. Hr ( 257,2 ) and 2nd coevals map Kc = { 01,11,10,00 } is generated by utilizing Hc ( R2, V2 ) i.e. Hc ( 36,3 ) , after that by utilizing equation ( 2 ) calculate the mean different value ‘D’ = ( 96/3 ) =32 which is greater than threshold value T, so the present block has been positioned in border country and is embedded Q = 5 Numberss of spots of secret informations in each peculiar pel. Hence, sum entire 4 * 5 = 20 spots are embedded in given block. Here for first pel into the block, e.g. y0 = 210, the initial part of secret informations ’10010’ is split into the two sub-strings ‘100’ and ‘10’ . Then, we get one = 2 and j = 3 because the 6th constituent of Kr is ‘100’ and 4th constituent of Kc is ‘10’ . Harmonizing to equation ( 3 ) , we compute‘d’ utilizing 8 * ( 2–1 ) +3 = 11. After that, the pel group ‘G’ is formed for the pel value y0 = 210 with n == 32. Here g 19= 210. Finally, the stego-pixel y`0 can be achieve from the dth component of G, i.e. y`0 = g24 = 202. Likewise we can happen leftover stego-pixel y`1 = 249, y`2 = 201, y`3 = 185 and therefore stego-block ( 202,249,201,185 ) is achieved. After using readjusts process we get concluding stego-block ( 202, 241, 201, and 185 ) . 2.1.2The pull outing stage in proposed adaptative strategy Like the implanting procedure, Partition the stego-image into four-pixel blocks. The undermentioned flow chart for pull outing informations from stego image in proposed adaptative strategy explains elaborate working flow The undermentioned stairss are executed to pull out the secret information. Measure 1: Input signal Stego Image, Secret keys R1, R2, v1, v2, T Step2: Generate Kr & A ; Kc Using R1, R2, v1, v2 Step3: Initialize i=0 & A ; j=0 Measure 4: if I & lt ; =M & A ; j & lt ; =N, travel to step 5 else halt. Measure 5: Calculate Average Diff ‘D’ utilizing combining weight. ( 2 ) Measure 6: Exploitation Threshold ‘T’ and ‘D’ find smooth block, Edge block and mistake block. i.e. a ) If D & lt ; =T, D belongs to Smooth block. B ) If D & gt ; T, D belongs to Edge block. degree Celsius ) If D & lt ; =T and ( ymax-ymin ) & gt ; 2*T+2, D belongs to Error block. Measure 7: Create pel group utilizing n=2^Q and degree Fahrenheit ( Lolo ) =yi mod n+1 Measure 8: Determine place information‘d’ . Measure 9: From‘d’ extract secret informations. Example For case, we extract the implanting illustration ( 151, 88, 193, and 133 ) , which is shown in the before subdivision. Assume v1 = 2, v2 = 3, R1 = 257, R2 = 36 and T = 25. The coevals map Kr = { 001, 110,101,010,111,100,011,000 } is formed by utilizing Hr ( R1, V1 ) i.e. Hr ( 257,2 ) and Kc = { 00,10,11,01 } by utilizing Hc ( R2, V2 ) i.e. ( 36,3 ) are produced. Here D & gt ; T, hence this block is placed in edge country and hence Q = v1 + v2 = 3 + 2 = 5 spots have embedded into each Pixel in the block. In present block sum, 4 †¢ 5 = 20 spots are embedded. Let us see 3rd pel into the block ( e.g. y â€Å" 2 = 202 ) . The pel group G is created for value 202 via Eq. ( 5 ) With n = 32. We create the variant Cartesian merchandise Kr _ Kc, which is value 202 with n = 22+3= 32. The place of stego-pixel 202 in G is 1, because vitamin D = ( 202 mod 32 ) + 1 = 3. The piece of binary secret informations ‘00001’ can be extracted because ‘00001’ is the 3rd constituent of Kr _ Kc. In the same manner, has extracted the secret information subdivision ‘10010’ for Yâ€Å"0, ‘10111’ for Yâ€Å"1and ‘11010’ for Yâ€Å"3. Finally we achieve ‘10010101110000111010’ which is the similar secret information informations in the implanting illustration of before subdivision.

Does Tv Have Negative Effect On Society

TV corrupts our children. Jerome Singer once said, â€Å"If you came and saw a strange man teaching your kids to punch each other, or trying to sell them all kind of products, you’d kick him right out of the house, but here you are; you come in and the TV is on, and you don’t think twice about it. † He is correct; entertainment television is an especially bad influence on children for many reasons, including not enough control on violence.These things are quite literally ruining America by corrupting our next generation’s leaders, our children. This year, more American children will die from a fired gun than from children who will die of asthma, pneumonia, influenza, cancer, and AIDS combined. What does this have to do with TV? Multiple studies have come to the conclusion that youth who are avid TV watchers become aggressive adults.A study from the University of Michigan showed that children who watched violent TV were more inclined to show violent tendenc ies as adults. According to that study, â€Å"†¦men who were high TV-violence viewers as children were significantly more likely to have pushed, grabbed or shoved their spouses, to have responded to an insult by shoving a person, to have been convicted of a crime and to have committed a moving traffic violation. Such men, for example, had been convicted of crimes at over three times the rate of other men.†It also stated that, â€Å"Women who were high TV-violence viewers as children were more likely to have thrown something at their spouses, to have responded to someone who made them mad by shoving, punching, beating or choking the person, to have committed some type of criminal act, and to have committed a moving traffic violation. Such women, for example, reported having punched, beaten or choked another adult at over four times the rate of other women. † The study also reported that the said violence was glorified by being black and white.The â€Å"good guysâ €  were okay to shoot the â€Å"bad guys,† resulting in a happy ending. This leads to children trying to be the good guys, by resulting in violence instead of working or talking the problem out. Another problem is that the â€Å"bad guys† have little to no back-story, with usually nothing more than a nickname to identify them with. Most of these problems base off the fact that children under 8 cannot tell the difference between fantasy and reality.Which covers another topic not censored enough. In conclusion, television is a sinister vehicle for bad habits of all sorts. How can you prevent this from happening to you and your families? The answer is simple: limit TV time to two hours a day. One might be reluctant to do so, but look what the old telly can and will do to America. As Nicholas Johnson said, â€Å"All television is educational television. The question is: what is it teaching? † .
