Planning Function of Management Essay Example for Free
Planning Function of Management Essay Planning is a crucial function of management that enables an organization to achieve its maximum potential. Halliburton is one of the largest corporations in the United States, with a workforce of over 100,000 people in over 120 countries. Their home office is located in Houston, Texas and they are one of the worlds largest providers of products and services to the oil and gas industry. This paper will discuss the issues impacting and influencing management planning within Halliburton. Management is doing things right; leadership is doing the right things. Peter DruckerIt takes successful management at all levels and quality leadership to lead a business down the proverbial golden path. Planning is the primary management function, which formalizes an organizations goals and objectives and establishes a base for the other functions of management. Halliburton Company is an oilfield services company and a provider of engineering and construction services that was founded in 1919. The company has expanded through tremendous internal growth and several acquisitions and in March, 2002, Halliburton split into two main divisions: the Energy Services Group (ESG) and Kellog Brown and Root (KBR). ESG offers a wide range of products and services to upstream oil and gas customers worldwide, ranging from the manufacturing of drill bits and other downhole and completion tools and pressure pumping services (www.halliburton.com) [APA citation error (incorrect-do not use Web addresses or URLs in citations). If the author is cited in text = Authors name (year) direct quote (p. #). If the author is not cited in text = direct quote (author, year, p. #).] . KBR is the engineering subsidiary for Halliburton and is a global leader in construction and project management. Additionally, KBR is a leading government services contractor, which has been t he focal point of many legal and ethical issues. Halliburton has received a great deal of negative publicity over the past year or so regarding it Iraq and Kuwait operations. The Pentagon and Justice Department have both launched criminal investigations due to erroneous contract cost estimates totaling $2.7 billion to serve American troops inà the middle east. Accusations have been made of overcharging for meals supplied to troops in Iraq, as well as employees accepting kickbacks from a Kuwaiti subcontractor. Pentagon auditors found that KBR overcharged the U.S. government by $27.4 million during a period of nine months in 2003. Additionally, Halliburtons internal audit revealed employees accepted these kickbacks in exchange for providing Army supply contracts to the subcontractor (Associated Press). Limited military spending has created lucrative opportunities for privately held companies such as Halliburton to win these contracts and will continue to be at the forefront of media campaigns as long as the United States remains in Iraq, especially when it comes to Dick Cheney. [You have addressed the issue thoroughly and supported your assertions.] Much speculation has been generated in regard to current Vice President of the United States and former Halliburton CEO Dick Cheneys financial ties to his former company. On the September 14, 2003 edition of NBCs Meet the Press, Vice President Cheney said, And since I left Halliburton to become George Bushs vice president, Ive several all my ties with the company, gotten rid of all my financial interest. I have no financial interest in Halliburton of any kind and havent had, now, for over three years (St. Louis Journalism Review). However, it came to light that Cheney received a salary of over $150,000 and maintained over 400,000 shares of unexercised stock options at the time. Cheney stated that he deferred his salary and stock options; therefore it did not constitute a violation of ethics. The Congressional Research Service found that these financial interests in Halliburton demonstrated a financial interest with his former employer creating a conflict of interest. Despite the fact that Cheney broke the law of ethics, he is exempt from the enforcement of such laws and cannot be prosecuted for it (Halliburton Watch). KBR is the largest military contractor in Iraq, with more than 50,000 employees and subcontractor working there and in Kuwait and Afghanistan. These employees drive trucks, wash clothes, deliver mail, and provide additional support services for the U.S. troops. These workers are part of the Pentagons privatization strategy that enables the military to reduce the number of troops needed in a given location by assigning noncombat functions to civilians. Halliburtons social responsibility is to keep theseà workers safe and away from fighting, but it has proved a difficult task. Numerous complaint and lawsuits have surfaced because of Halliburtons failure to provide safe working conditions and in the case of one man who was killed, the suit states he was intentionally sent the convoy as an enemy decoy in the U.S. military camouflage vehicles, to ensure the safe arrival and delivery of a second H-KBR fuel convoy (CNNMoney.com). Halliburtons social responsibility remains in question with workers being placed in harms way on a regular basis. Factors influencing Halliburtons strategic, tactical, operational, and contingency planning include political instability, rising steel prices, and environmental regulations. Halliburton operated in countries such as Iran, Iraq, Nigeria, Afghanistan, Indonesia, and Russia, which are currently experiencing unstable political and social climates. Continued conflict in these areas could have an impact on the companys bottom line and their ability to generate substantial revenue. Steel is a major commodity that is used in the setting up of plant and processing facilities for natural gas and petroleum refining. Record breaking high prices were reached in early 2005, but have since stabilized. However, the ongoing consolidation in the steel industry could lead to higher prices causing the profit margins to suffer. Lastly, Halliburton is subject to environment and legal requirement in its worldwide operations, such as the Clean Air Act and Clean Air Interstate Rule, causing the states to re duce the allowable sulfur dioxide SO2 emissions by 70% and nitrogen oxides emissions by 60%. Environmental issues such as these could place a burden on is cash flow. [Insightful analysis]Halliburton has an exceptional global presence and they are currently playing a prominent role in rebuilding Iraq and by providing our troops with shelter, meals, and delivery of materials. Although Halliburton has come under intense scrutiny over the past several years due to its involvement with Vice-President Chaney and its legal and ethical issues, it has still managed to win military contracts due to its expertise in the oil service industry. This shows tremendous resiliency and reassures its customers and stockholders that it will continue to be a strong force in the oilfield services industry. [Your paper is well written.

Politics Essay -- essays research papers
Politics: the inescapable stalker of our society Politics is a process by which a group of people, whose opinions or interests might be divergent, reach collective decisions that are generally regarded as binding on the group and enforced as common policy. Political theory or political philosophy is as old as the oldest civilisations. The Greek philosophers, such as Aristotle and Plato, developed important political theories and methods of government alongside their more abstract philosophies. One may contest that every society and every belief we hold is a reflection of the political system we live under. Politics, in it absolute form, is a concept of society that definitely intrudes into every aspect of human life. No one can escape it. The word politics comes from the Greek word ââ¬Å"polisâ⬠, meaning the state or community as a whole. The concept of the ââ¬Å"polisâ⬠was an ideal state and came from the writings of great political thinkers such as Plato and Aristotle. In his novel "The Republic", Plato describes the ideal state and the means to achieve it. Hence, the word politics originally has connotations in the ways in which to create the ideal society. An ideal society is in practice a rather difficult aim and even an impossible aim to achieve. Imperfections in society inspired Aristotle and Plato to compose the first written political philosophies. In Aristotle's ââ¬Å"The Politicsâ⬠, he states that, ââ¬Å"Man is by nature a political animalâ⬠, in another words, it is a primal instinct of man. Therefore, in his statement, Aristotle concludes politics is not a dreamt up concept, but rather an inherent feature of mankind. Argument, in our lives and about the way that we live t hem is a fundamental part of our sociological make-up. A main factor in modern government is what is dubbed ââ¬Å"Party Politicsâ⬠. Each party with its manifesto attempts to gain parliamentary superiority over others in each general election. People vote for the party that broadly represents the individual's values. Although, the average turnout for elections The most common method of categorising political theories is by use of a horizontal line from right to left (the far and moderate right, the right of centre, the centre and the left of centre, the moderate left, and the far left) gradually. What follows is an attempt to clarify this contentious issue of categorisation. It is not a defin... ...onflict and change. Politics is the means to creating a more organised and peaceful society, by providing methods to resolve conflict that naturally occurs in society. From this, politics also endeavours to further society to perfection and to create an absolute harmony between the ruling body and the populace. It thus aims to replace violence and prevent us from returning to chaos. Authority and order are the underlying features of politics and ensures its enforceability. Power underscores its very existence; it is necessary for politics exist. Without authority, politics simply is not feasible. The most visible and widely accepted example of politics is the workings of the governmental institutions. However, although at first glance one may not be aware of it, politics in its various forms is present wherever and whenever humans form a community. Returning to the writings and beliefs of Aristotle, politics is an intrinsic feature of mankind. References ââ¬Å"Politicsâ⬠, Heywood, Palgrave. 1997 ââ¬Å"The Republicâ⬠, Plato (Tr Des.

Market structure
Four basic types of market structures are: 1- Perfect competition 2- Monopolistic competition 3- Oligopoly 4- Monopoly There is also another market structure called Monopoly. 1- Perfect competition It is considered more theoretical than practical, because it is very rare. In perfect intention a large number of firms sell identical products, where none of them has pricing power. There no berries or very easy to enter to the market by any new farm. Prices. For example if we go to normal retail shops to buy vegetables, we will get at same prices from each and every shop.Fish market at Male' is a very good and a simple example, where inside the market lot of sellers will be selling same fishes. Prices will be set by the demand and supply. Neither buyer nor seller sets the price. It is more like automates pricing. Characteristics of perfect competition include large umber of small firms, identical products, perfect resource mobility and perfect knowledge. 2- Monopolistic competition It is almost like perfect competition where large number of small firms sells similar but not identical products. Relative freedom of entry, to and exit from the industry.It means buyers will have substitutes to choose from. Alternatives to buy for fulfill their needs and wants. Examples of industries structures as monopolistic competition includes, clothing industry, restaurants, and shoes and so on. 3- Oligopoly It is a market situation where products are supplied by small number of firms where ACH of them has influence over pricing and supplies which directly effects the position of the competitors. I oligopoly there is a special case where there is only two producers are called Duopoly. 4- Monopoly This is a market structure where only one producer in a market who has to the total control.Buyers do not have substitutes and have no choice. They have total control over supply and prices. In this market structure, seller is always happy and consumers suffer. They take more profit with a huge marginal value from the products. Characteristics of monopoly includes single seller, unique product, berries o entry and specialized information. The fifth type of market structure which is not included in basic structures is Monopoly. It is upside down of a monopoly where there is only one buyer. If we relate to a Mammalian context, government is the only buyer for the explosives and guns. Where there may be many sellers.Exhibit 1 Perfect Competition Monopolistic Competition Oligopoly Monopoly Number of Sellers Many Few One Barriers to Entry Very Low Low Very High Type of Substitute Products Very good Good substitutes but differentiated Very good differentiated substitutes No good substitutes Nature of competition Price only Marketing, features and price Advertising Pricing Power None Little Little to significant Significant As mentioned above, from 1988 to 2005 telecommunication industry of Maldives was a monopoly market. The following will elaborate how it was a monopoly a nd what was the situation during the monopoly. 988-2005 Draught monopoly in Maldives It was history that people used to call Draught as ââ¬Å"Blood Suckersâ⬠. When the company started in the Maldives in Maldives there was a telecommunication service by cable and wireless which uses USB set to communicate between the islands. After their establishment as one and only telecoms service provider in 1988 they brought a major upgrade to their network in 1989 in Male and introduced paging service in the Maldives. They also introduced internet service for the very first time in Maldives in 1996 followed by mobile phone service in 1997 which was upgraded to GSM in 1999.Being the only company to provide the service and major share controlled by the government of the Maldives, they introduced services at a huge marginal value. Consumers have no substitution in the market, which lead Draught to grow up and cake huge profit and extended its service to nationwide, while charging extraordina ry high charges to cover its expansion costs and making more profit. It is usual to charge more from the consumers in monopoly market structure. In monopoly, always seller is always happy and consumers are unhappy.Some pros and cons of monopoly are: Advantages Disadvantages Large capital scale benefit to the company More money to invest on development Earning national export revenues Price discrimination between consumers Very high market share Restricts production potential Do not actively pursue new clients Poor product quality Unfair wealth distribution Entry barrier for new comers When Waiting telecoms Maldives (presently called Ordered) started their service officially in Maldives on 1st August 2005 shortly after they were licensed on 1st of February 2005, the market structure changed to an oligopoly.Oligopoly In economics oligopoly means that there are few sellers of a certain product in a market. Usually these sellers are always in a high competition with each other. In this type of markets sellers knows very well about their competitors. They have a high power to in pushing their products to the consumers. When on seller makes a change, it will directly affect other sellers. There is a special case in oligopoly which is called duopoly. Which is when the there is only two sellers in the market. Here are some advantages and disadvantages of oligopoly.Advantages Lot of control Ability to fix prices Competitive pricing More profit making Perfect knowledge of the market Price controlling will be a disadvantage for consumers Creative ideas may fail to realist Difficult for small firms to establish in the market Not much of competition No fair wealth distribution Oligopoly in Maldives telecoms industry From 2005 Ordered became the major and the only competitor to Draught. As usual they have initiated their business with a huge investment to make existence of their network across the Maldives.It was a huge challenge for them to establish when there was a well- established and government controlled seller in the marker for almost a decade, market share was 100% controlled by monopolized Draught. Immediately after starting the service in the market by the new comer, the unhappy customers of the monopolized industry started to change their service provider. They started with introductory promotional prices which was far much better than the ajar market controller, which directly affected the business of Draught. Competition, strengths and weaknesses.When there are two or more sellers are there in a market, it is obvious that the competition will be born in the market. It is very interesting to study about the competition between Ordered and Draught. Luckily I have got very good connections at the top levels of both the companies, which made me to sit and talk about their respective companies. I found that they are tightly in competition with each other. Pricing: When Draught was alone in the industry, consumers pay around USED $100 average u ser used to pay around MOVE 2000 per month for the usage. Call rates are sky high.Rates differ from calls from mobile to mobile and mobile to landlines. When the competition started and if we see current situation, we have choices for individuals and businesses depends on what consumer needs. There are some consumers who want more talk time than data while others doesn't care about the talk time but data allowance the service provider offers. Those used to spend around 2000 per month now are spending less than 500 per month because of competitive pricing by the competitors. Advertising: Earlier days Draught keeps and average advertising.Unlike that now each and every TV channel is occupied by both Draught and Ordered advertisements. All the islands with more population see those companies' bill boards near harbors and schools. It is very clear that Ordered is doing more aggressive advertising while Draught use more informative advertising. Corporate Social responsibility: We used to say that both the companies do corporate social responsibility to a certain extent. But in real, in my study I found that rather than corporate social responsibility they both do corporate philanthropy. They do not actively participate in social activities.But they do help by donation some money to do the social activities by others. That is a form of advertisement they both do. They are present in the activities as bill boards. Just to advertise the company name. For example: Thieved league football tournament is always sponsored by one of these two companies. Competitive advantages: Draught uses ââ¬Å"first in Maldivesâ⬠ââ¬Å"Largest networkâ⬠and so on while Ordered uses ââ¬Å"best network for smart phonesâ⬠. Draught is first to come and still holds 65% market share while Ordered is gaining market share at a rapid speed.Bad the backbone of the company is much better with latest technologies while Draught is upgrading its backbone. Subsidized handsets to consum ers: Ordered started offering Samsung handset to its consumers with contract for the very first time in Maldives. And soon they will be starting offer apple handsets on contract, while Draught is working with apple to introduce subsidized apple handsets with contract. Apple currently certified Ordered network for their products while Draught is doing upgrades to obtain certification of using Apple products on contract. Is this industry good for the society?Unlike the history of the monopoly in the telecommunication industry in the Maldives, with existing oligopoly (duopoly) consumers are happy now. As is economic theory, human wants are unlimited with the scares resources available, people are still aiming for mush cheaper services with better quality. As mentioned earlier in this report, consumers' expenses, for the use of telecommunication are decreased by 60 percentages. We never heard of handset for installments by service providers before. But it is started now. We have heard a bout subsidized handset with contract with carrier locked, from other parts of the world.We never imagined that a small country with a small population like us will get phones on contract with subsidized prices. But it is soon to happen. Unlike perfect competition and monopolistic competition there are no much of sellers. So competition and pricing of the products will not be according to the demand and supply. Sellers will have the power to set the prices. Consumers are very happy when there is a perfect competition and monopolistic competition. Consumers are sad at most when there is a monopoly. But than they used to have, the monopoly. It is an average good for the society.

Glucose Molecular Formula and Facts
The molecular formula for glucose is C6H12O6 or H-(CO)-(CHOH)5-H. Its empirical or simplest formula is CH2O, which indicates there are two hydrogen atoms for each carbon and oxygen atom in the molecule. Glucose is the sugar that is produced by plants during photosynthesis and that circulates in the blood of people and other animals as an energy source. Glucose is also known as dextrose, blood sugar, corn sugar, grape sugar,à or by its IUPAC systematic nameà (2R,3S,4R,5R)-2,3,4,5,6-Pentahydroxyhexanal. Key Takeaways: Glucose Formula and Facts Glucose is the most abundant monosaccharide in the world and the key energy molecule for Earths organisms. It is the sugar produced by plants during photosynthesis.Like other sugars, glucose forms ismomers, which are chemically identical, but have different conformations. Only D-glucose occurs naturally. L-glucose may be produced synthetically.The molecular formula of glucose is C6H12O6. Its simplest or empirical formula is CH2O. Key Glucose Facts The name glucose comes from the French and Greek words for sweet, in reference to must, which is the sweet first press of grapes when they are used to make wine. The -ose ending in glucose indicates the molecule is a carbohydrate.Because glucose has 6 carbon atoms, it is classified as a hexose. Specifically, it is an example of an aldohexose. It is a type of monosaccharide or simple sugar. It may be found in either linear form or cyclic form (most common). In linear form, it has a 6-carbon backbone, with no branches. The C-1 carbon is the one bearing the aldehyde group, while the other five carbon each bear a hydroxyl group.The hydrogen and -OH groups are able to rotate around the carbon atoms in glucose, leading to isomerization. The D-isomer, D-glucose, is found in nature and is used for cellular respiration in plants and animals. The L-isomer, L-glucose, is not common in nature, although it may be prepared in a lab.Pure glucose is a white or crystalline powder with a molar mass of 180.16 grams per mole and density of 1.54 grams per cubic centimeter. The melting point of the solid depends on whether it is in the alpha or beta conformation.à The melting point ofà à ±-D-glucose isà 146à à °C (295à à °F; 419à K). The melting point ofà à ²-D-glucose isà 150à à °C (302 à °F; 423 K).Why do organisms use glucose for respiration and fermentation rather than another carbohydrate? The reason is probably that glucose is less likely to react with the amine groups of proteins. The reaction between carbohydrates and proteins, called glycation, is a natural part of aging and consequence of some diseases (e.g., diabetes) that impairs the functioning of proteins. In contrast, glucose may be enzymatically added to proteins and lipids via the process of glycosylation, which forms active glycolipids and glycoproteins.In the human body, glucose supplies about 3.75 kilocalories of energy per gram. It is metabolized into carbon dioxide and water, producing e nergy in chemical form as ATP. While its needed for many functions, glucose is particularly important because it supplies nearly all the energy for the human brain.Glucose has the most stable cyclic form of all the aldohexoses because nearly all of its hydroxy group (-OH) are in the equatorial position. The exception is the hydroxy group on the anomeric carbon.Glucose is soluble in water, where it forms a colorless solution. It also dissolves in acetic acid, but only slightly in alcohol.The glucose molecule was first isolated in 1747 by the German chemist Andreas Marggraf, who obtained it from raisins. Emil Fischer investigated the structure and properties of the molecule, earning the 1902 Nobel Prize in Chemistry for his work. In the Fischer projection, glucose is drawn in a specific configuration. The hydroxyls on C-2, C-4, and C-5 is on the right side of the backbone, while the C-3 hydroxyl is on the left side of the carbon backbone. Sources Robyt, John F. (2012).
