For the duration of the connection, all the resources on that circuit are unavailable for other users. Voice calls using the Internets packet-switched system are possible. Each end of the conversation is broken down into packets that are reassembled at the other end. The principles of packet switching are as follow. Messages are divided into data packets, which are then directed through the network to their destination under computer control. Besides a message portion, each packet contains data concerning. The principles of packet switching are as follow. Messages are divided into data packets, which are then directed through the network to their destination under computer control. Besides a message portion, each packet contains data concerning: Â  The destination of the address; Â  The source identification; The sequence of the packet in the complete message; Â  The detection and control of transmission errors. Â  Pre-determined routing. With this method, the routing details are included in the packet itself, each switching exchange forwarding the packet according to the embedded instructions; Â  Directory routing. Each switching exchange has a copy of a routing table to which it refers before forwarding each packet. The appropriate output queue is determined from the table and the packet destination Diagram shown below: Identify three types of cabling used in data communication. State which one you would recommend in an implement requiring high security consideration and why? The three types of cables used in data communication are: Optical Fiber Coaxial Coaxial cable is a copper that is used by TV companies between the community antenna, and also the user homes and businesses. At times these cable are also used by telephone companies from their central office to the telephones near users. This is also widely installed for use in business and corporation Ethernet and other types of local area network. Coaxial cable is called coaxial this is because this includes one physical channel that carries the signal surrounded (after a layer of insulation) by another concentric physical channel, both running along the same axis. The outer channel serves as a ground. Many of these cables or pairs of coaxial tubes can be placed in a single outer sheathing and, with repeaters, they can carry information for a great distance. This is a diagram shown below: UPT UPT stands for Unshielded twisted pair. This cable is the most common kind of copper telephone wiring. Twisted pair is the ordinary copper wire that connects home and many business computers to the telephone company. To reduce crosstalk or electromagnetic induction between pairs of wires, two insulated copper wires are twisted around each other. Each signal on twisted pair requires both wires. Since some telephone sets or desktop locations require multiple connections, twisted pair is sometimes installed in two or more pairs, all within a single cable. For some business locations, twisted pair is enclosed into a shield that functions as a ground. This is known as shielded twisted pair (STP). The twisted pair is now frequently installed with the two pairs to the home, with the extra pair making it possible for you to add another line (perhaps for use of a modem) when you will need it. These twisted pair comes with each pair uniquely colour coded when it is packaged in multiple pairs. Different uses such as analogue, digital, and Ethernet require different pair multiples. Although twisted pair is often associated with home use, with a higher grade of twisted pair is often used for horizontal wiring in LAN installations because it is less expensive than coaxial cable. The wire that you buy at a local hardware store for extensions from your phone or computer modem to a wall jack is not twisted pair. It is a side-by-side wire known as silver satin. The wall jack can have as many five kinds of hole arrangements or pin outs, depending on what kinds of wire the installation you expects that will be plugged in (for example, digital, analogue, or LAN) . (Thats why you may sometimes find when you carry your notebook computer to another location that the wall jack connections wont match your plug. ) This is a diagram shown below: Optical Fiber. Optical fiber (or fiber optic) refers to the medium and the technology associated with the transmission of information as light pulses along a glass or plastic wire or fiber. Optical fiber carries much more information than the conventional copper wire and is in general not subject to electromagnetic interference and the need to retransmit signals. Most telephone company long-distance lines are now of optical fiber. Transmission on optical fiber wire requires repeaters at distance intervals. The glass fiber requires more protection within an outer cable than copper. For these reasons and because the installation of any of the new wiring is labour-intensive, few communities yet have optical fiber wires or cables from the phone companys branch office to local customers (known as local loops). A type of fiber known as single mode fiber is used for longer distances; multimode fiber is used for shorter distances. This is the diagram shown below: By analyzing and researching the three above cable I would recommend the Fiber Optic cable this is because I believe it has a high security and also has the following. Fiber optic cables have a much greater bandwidth than metal cables. This means that they can carry more data. Â  Fiber optic cables are less susceptible than metal cables to interference. Fiber optic cables are much thinner and lighter than metal wires. Data can be transmitted digitally (the natural form for computer data) rather than analogically. Identify the alternative forms of communication media and provide examples of their use in different forms of network. Microwave Microwave frequencies require a direct line of sight between sending and receiving station to operate. Microwave systems were the preferred method of communications transmission before the introduction of fiber optic. Radio The lowest-frequency domain that needed to name. This extends from wavelengths of a kilometre or so, the longest that will propagate through the interstellar medium, down to about a millimetre. The detection of radio radiation is often done using wave techniques rather than photon-counting, this is because of the low photon energies, and this offers distinct advantages for such applications as interferometer which astronomers working in the infrared and optical regimes view with some envy. From active nuclei, we often detect the synchrotron radiation in this range radiation produced energetic charged particles (mostly electrons) produce when they are deflected by the magnetic fields. a) Define the basic signal theory with the aid of diagrams? 1) In electronics, a signal is an electric current or electromagnetic field that is used to convey data from one place to another. The simplest form of signal is a direct current (DC) that is switched on and off; this is the principle by which the early telegraph worked. More complex signals consist of an alternating-current (AC) or electromagnetic carrier that contains one or more data streams. Data is superimposed on a carrier current or a wave this is by means of a process called a modulation. Signal modulation can be done by two main ways: analogue and digital. In recent years, digital modulation has been getting more common, while analogue modulation methods have been used less and less. There are still plenty of analogue signals around, however, and they will probably never become totally extinct. Except for DC signals such as telegraph and base band, all signal carriers have a definable frequency or frequencies. Signals also have a property called wavelength, which is inversely proportional to the frequency. 2) In some information technology contexts, a signal are simply that which is sent or received, thus including both the carrier and the data together. 3) In telephony, a signal has a special data that is used to set up or control communication. Almost everything in the world can be described or represented in one of two forms: analogue or digital. The principal feature of analogue representations is that they are continuous. In contrast, digital representations consist of values measured at discrete intervals. Digital watches are called digital because they go from one value to the next without displaying all intermediate values. Consequently, they can display only a finite number of times of the day. In contrast, watches with hands are analogue, this is mainly because the hands move continuously around the clock face. As the minute hand goes around, it not only touches the numbers 1 through 12, but also the infinite number of points in between. Early attempts at building computers used analogue techniques, but the accuracy and reliability were not good enough. Today, almost all computers are digital. Analogue and Digital Technology Analogue and Digital are the words we hear when people talk about Communication and Information Technology. What do the words Analogue and Digital mean? Analogy means a likeness between two things that are really quite different. For example the analogy between the brain and the computer or the heart and a pump. Digit means either a finger or toe, or one of the numbers 1 to 9. Some examples might help to explain what analogue and digital mean in technology. A simple example of analogue and digital technology Clocks are examples of analogue and digital technology. An analogue clock face can display the time without numbers. The hands keep moving all the time and they continue to rotate, just like the earth around the sun. This is the analogy between the movement of the sun and earth, and the hands of the clock. The digital clock displays the time in numbers, and the time displayed only changes at each minute. In the analogue clock the hands keep moving all the time, while the digital clock is more like an on and off movement. Each minutes the time moves and then stops for another 60 seconds, when it changes again. Some other examples of displaying information using analogue and digital forms. b) How the signal theory affects the choice of transmission methods and media? Analogue and Digital Signals Sound can be converted into analogue and digital electrical signals. Analogue Signal A microphone or handset of a telephone will convert sound into an analogue signal. The shape of the wave seen on an oscilloscope represents the volume and pitch. The diagram is shown below: This is called an analogue signal because, when the volume and pitch change, so does the shape of the wave. The signal is an analogue of the sound. Digital signal Today we see many sound systems described as digital. This means the sound is converted into digital signals so it can be transmitted or recorded. In the microphone example shown on the diagram above, the analogue signal is converted into a digital signal by electronic circuits. In a digital signal the electricity, this can be either on or off, is combined with a binary code. The voltage of the analogue signal is measured electronically, many thousands of times per second, by an analogue-digital converter. The analogue signal is converted into a 16 bit binary number, which gives 65,536 levels of voltage. In electronics 1 = ON and 0 = OFF. This means the binary number can be converted into an electrical signal. A diagram below shows the process of converting analogue signals into a binary numbers and digital signals. To keep the explanation simple the analogue signal has been converted into a 3 bit binary number, which means there are seven voltage levels. A digital-analogue converter reverses the conversion this is because the speakers (output device) need an analogue signal. Light and sound can be converted into binary numbers and digital signals that are used to record and transmit information. This diagram is shown below: Why are digital systems better than the analogue ones? An analogue signal is affected by changes in the voltage as it travels along a wire. If the voltage changes, so does the signal at the output. The digital signal is not affected by changes in the voltage this is because all that matters is whether it is ON or OFF. How signal affects transmission methods? Noise is any sound on the CD or record that wasnt there at the performance during the recording session. More generally, it is any unwanted signal that adds on to the information that is being transmitted. When a vinyl record is being made, noise is introduced at every step of the recording process, although of course the company makes an every effort to reduce such noise to as low a level as possible. The sound that reaches the microphones is converted into an electrical signal that is then recorded on a wide magnetic tape moving at high speed. This tape is then used to control the cutting of a master disc, from which moulds are then made. These in turn are used to mass-produce the records that are eventually sold in shops. Noise is produced at every step, not forgetting that introduced by your own stereo equipment. It can never be entirely eliminated. The same problems of noise are shared by any method of transmitting information, and are certainly by telecommunications, including telephone calls. In the production of vinyl records, the companies have used purely analogue this means to transfer the information representing the sound of the music from one point to another. That means they use an electrical signal that changes smoothly in strength, exactly modelling the smooth but complex changes in the sound. When a noise is created in the recording process because of tape hiss, dust on the master disc, electrical interference or any other cause this is added on as a random signal on top of the complex electrical signal representing the sound. There is no way that electronic equipment can tell such random noise from the original electrical signal, so there is no way it can be removed again without removing some of the original signal. We can see more clearly if we draw a graph of the level of the analogue audio signal over a period of time (diagram 1a). The shape of this graph represents both the changes in the electrical sound and the changes in the electrical signal that model it. Now if we add to this audio signal some random noise, this affects the shape of the signal, and this degrades the sound that your stereo reproduces (diagram 1b). The trouble with an analogue audio signal is that its exact shape has to be preserved if you are to hear the music exactly as it was when it was played. If there were a means of transmitting the signal so that only the overall shape of the signal mattered, then noise would not be so important. The port authorities used to find the shape of the bottom of the harbour, so that ships could navigate more safely. It certainly wasnt possible to drain the harbour and take a photograph of it, so what they did instead was send out a boat which travelled slowly across the harbour. Every few meters a person at the back of the boat dropped down a plumb-line (a weight at the end of a rope), until it reached the bottom of the harbour. The line had knots tied in it at regular spaces and the person called out the number of knots under water, so indicating the depth of the harbour at that point. A clerk wrote these down, and eventually it was possible for him to draw a graph of the shape of the harbour by using these numbers. The person in the boat had been taking samples of the depth of the harbour at frequent intervals, so that the graph would accurately describe the ups and downs of the harbour bottom.

Kinetic Molecular Theory of Gases

Kinetic Molecular Theory of Gases Regina Marin Gas is called the state of matter in which, under certain conditions of temperature and pressure, its molecules cross-react only weakly with each other without forming molecular bonds, taking the shape and volume of their container and tending to separate , and expand, their best for their high kinetic energy. Gases are highly compressible fluids that experience large changes in density with temperature and pressure. Molecules constituting a gas almost are not attracted by each other, so that they move in space at high speed and quite separated from each other, thus explaining the properties: The gas molecules are virtually free, so that they are able to be distributed throughout the space in which they are contained. The gravitational attraction and forces between molecules are negligible compared to the rate at which the molecules are moving. Gases completely occupy the volume of their container. Gases have no definite shape, embracing the vessels containing them. Can easily be compressed, because there are large gaps between molecules, and other. At ambient temperature and pressure gases can be elements such as hydrogen, oxygen, nitrogen, chlorine, fluorine and noble gases, compounds such as carbon dioxide or propane, or mixtures like air. For the thermal behavior of particles of matter there are four measurable quantities that are of great interest: pressure, volume, temperature and mass of the sample material (or better amount of substance, measured in moles). Any gas is considered a fluid because it has properties that allow it to behave as such. Its molecules in constant motion, colliding elastically with each other and against the walls of the vessel containing the gas, against which exert a constant pressure. If the gas is heated, the heat energy is spent on kinetic energy of the molecules, that is, the molecules move more quickly, so that the number of collisions with the walls of the vessel increases in number and energy. As a consequence the gas pressure increases, and if the container walls are not rigid, gas volume increases. A gas tends to be chemically active because its molecular surface is also large, that is, to be its particles in continuous motion colliding with each other, this makes it easier the contact between a substance and another, increasing the rate of reaction in compared to liquid or solid. To better understand the behavior of a gas, where studies are conducted with respect to the ideal gas, although it never actually exists and its properties are: A pure gaseous substance consists of molecules of the same size and mass. A gaseous mixture is formed by different molecules in size and mass. Due to the large distance between molecules and other and that move at high speed, the forces of attraction between the molecules are considered negligible. The size of the gas molecules is very small, so that the volume occupied by the molecules is negligible compared with the total volume of the container. The density of a gas is very low. The gas molecules are in constant motion at high speed, so continuously collide elastically with each other and against the walls of their container. As part of the kinetic theory, the gas pressure is explained as the macroscopic result of the forces involved by collisions of gas molecules with the walls of the container. The pressure can thus be defined with reference to the microscopic properties of the gas. The kinetic theory of gases is a physical and chemical theory that explains the behavior and macroscopic properties of gases (ideal gas law), from a statistical description of the microscopic molecular processes. The kinetic theory was developed based on studies of physical and Daniel Bernoulli in the eighteenth century, Ludwig Boltzmann and James Clerk Maxwell in the late nineteenth century. This branch describes the thermal physical properties of the gases. These systems contain huge numbers of atoms or molecules, and the only reasonable way to understand the thermal properties based on molecular mechanics, we find certain dynamical quantities of average type and relate the observed physical properties of the system with t hese properties averaged molecular dynamics . Techniques to relate the overall macroscopic behavior of material systems with the average behavior of their molecular components are statistical mechanics. The main theorems of the kinetic theory are: The number of molecules is large and the average separation between them is large compared with their dimensions. Therefore occupy an insignificant volume when compared to the volume of the container and are considered point masses. The molecules obey Newton's laws, but individually they move randomly, each with different rates, but with an average speed that does not change with time. The molecules perform elastic collisions with each other, therefore both the linear momentum is conserved as the kinetic energy of the molecules. The gas is considered pure, in other words all molecules are identical. The gas is in thermal equilibrium with the walls of the container. As part of the kinetic theory of a gas pressure is explained as the macroscopic result of the forces involved by collisions of gas molecules with the walls of the container. The pressure can thus be defined with reference to the microscopic properties of the gas. It is generally believed that there is more pressure if the particles are in the solid state, if they are in liquid state is minimal distance between them and finally if you are in the gaseous state are far apart. Indeed, for an ideal gas with N molecules , each moving mass m with a random speed average content in a cubic volume V of the gas particles impacting with the wall of the container in a manner that can be calculated in a statistical manner exchanging momentum with the walls in each shock and effecting a net force per unit area that is the pressure exerted by the gas on the solid surface. The pressure can be calculated with this formula: The equation above states that the gas pressure is directly dependent on the molecular kinetic energy. The ideal gas law allows us to ensure that the pressure is proportional to the absolute temperature. These two statements allow one of the most important statements of the kinetic theory: The average molecular energy is proportional to temperature. The proportional constant is 3/2 is the Boltzmann constant, which in turn is the ratio of the gas constant R between the Avogadro number. So in a few words, the kinetic theory is a physical theory, based on a few facts: The density of the gas is very small. Individually molecules move randomly and at different speeds, which increases or decreases while the temperature and the movement causes them from hitting each other, increasing the pressure when striking more times. The cohesive forces or intermolecular forces in gases are almost nil. If all of the molecules forming the gas are identical, is said to be a pure gas.

Case Study of Business Strategy Of Marks And Spencer

Case Study of Business Strategy Of Marks And Spencer Marks and Spencer is one of the biggest traders having inheritance of more than one hundred and twenty years. It has more than 895 stores in more than 40 regions all over the world. Its head office is in U.K, in the city of Westminster. Michael Marks from Slonim, Russia and Thomas Spencer a cashier from Yorkshire are the pioneers of this U.Ks biggest retailers. At Leeds (Kirkgate market) in 1884, Michael Marks started his own business by opening a penny bazaar stall. Then to develop his business he opened a shop at Manchester with the partnership of Thomas Spencer. H:st college assingmentsMS assingq no 51201445_MarksSpencerSheffieldHistory.jpg After the death of both the pioneers of the company Michael Marks Simon became the chairman of company while William Chapman took the helm until 1960. During the Era of Michael Simon Company touch the highest point .The business was floated as a public limited company after 10 years. In 1998 it was the first company of U.K who earned the profit of one billion pounds after tax deduction. Marks and Spencer prohibited smoke first time in store that later on became a legal offence to smoke at public places. Marks and Spencer mainly deals in Clothing, Home Ware, Food, Technology, Beauty, Financial Services, Energy and Hospitality. PLAN A: The Customers are becoming more conscious about natural and environmental issues, so for this Marks and Spencer launched plan A, which consists of 180 commitments to overcome the challenges. Many problems are related with Climate Change, Waste Reduction, Ethical Trading, Sustainable Raw Material and Health. To tackle these changes Marks and Spencer is doing much effort. C:UsersFaisalDesktopimagesCAXD7DW8.jpg In March 2010 Marks and Spencer expanded plan A introduced 80 more commitments and added them up with the existing ones. In these commitments their primary focus is on climate changes, waste, natural resources, fair partner, health and well being. These five main pillars are described below: C:UsersFaisalPicturesimagesCAV6T6WW.jpg CLIMATE CHANGE: Due to an increase in greenhouse gases produced by the human activities the earth is getting warmer day by day causing many damaging consequences. In 2006/07 Marks and Spencer cut their carbon emissions to 8% by reducing the usage of energy. Marks n Spencer also committed that up to 2015, they will improve their energy efficiency by 35%. C:UsersFaisalDesktopimagesCA3FRFRV.jpg WASTE: Every year the U.K has to throw away 400 tonnes of waste that comes from construction, industry, households and discarded packaging. The waste that is not recycled ends up in landfill sites which take many years to decompose. Marks and Spencer claimed that in the year of 2009/10 they have achieved the recycling level to 88% while reducing the amount of waste to 16%.They have reduced the food waste by 29% as compared to the years 2006/07.Marks and Spencer collected 133 million clothes hangers and reused 76% of them and recycled the rest. C:UsersFaisalPicturesimagesCAM1CR39.jpg They have also recycled their construction waste up to 89%.Marks and Spencer are committed to do that by 2015 they want to landfill help their customers to recycle or reuse their packaging and products. They will also help their suppliers to reduce the waste and to gain zero rates as well. NATURAL RESORCES: In plan A Marks and Spencer aimed to get as much of their raw material from their natural resources as possible. It is the U.Ks first company who has signed the WWF sea food charter, with 62 % of their wild sea food. Marks Spencer also purchased Green palm certificate to cover all the palm oil to use their Marks and Spencer product. C:UsersFaisalPicturesimagesCAG3OZ2S.jpg Fair Partner: Marks and Spencer has a vision that they are very strong in their communities and ensure good working conditions. Marks and Spencer has the lowest employee turnover rate in UK retail i.e. 14%.Marks and Spencer is offering competitive salaries, discount to their employees, bonuses and share save options to their employees. It provides different training programmes to the employees. Every employee has to undertake Marks Spencer Career Path Training and learning programmes .While the managers have to attend the different workshops to boost their capabilities. Marks and Spencer is trying to provide the best salary packages for the employees. C:UsersFaisalDesktopimagesCAF15VPV.jpg Health and Wellbeing: Unhealthy food is one of the main factors of many health problems. According to the part of the commitment of Plan A Marks and Spencer encouraged its customers and employees to get healthy and nutritious food by developing new product ranges. Marks and Spencer has launched online diet forums and health newsletters to allow active dialogue with the customers on nutrition and health. Marks and Spencer has removed artificial flavours and colours from all of its food products and soft drinks. It has also removed 90% of salt in its products. Very few of the products still does not meet the required standard of health and nutrition but Marks and Spencer is working hard to bring it in line according to the required standard. C:UsersFaisalPicturesimagesCACFVO3Z.jpg Analysis of the external environment: According to plan A Marks and Spencer has also taken into consideration the external environment of the company. External environment means the factors that directly or indirectly affect the internal function and perhaps business strategy and objectives as well. Most common factors of external environment are political, social, economic and technical. These factors are totally out of control of the organisation, but the company could be able to take some steps to overcome these challenges. Basically the external environment defines the competitive situation of an organisation and potentially can have both positive and negative impacts on businesses. Target analysis has four major categories of external factors that affect the companys capability to grow. Based on operation region, external environment is divided into three interactive segments which is remote, industrial and operational environment. External factors produce different influences on the companys productivity. On the ot her hand some influences are inter-linked with each other. For example information technology completely changed the way of work, customer behaviour and life style as well. Based on PEST analysis four major factors are going to be discussed in detail. Political Environment: Political stability in a country attracts the investors to do investment and that is a very key factor to grow business. Secondly, government trade policy, is either flexible or hard. Every organisation operates under the government policy about trade and within the legal frame work. The legal frame work covers many areas like tax rates, employees benefits, wage legislation, trade regulation and tariff. Suppliers, customers and competitors are also affected by the political environment. Economical Environment: Economic conditions also affect organisations external environment. In this regard some factors that influence business are tax rates, inflation, money supply, government need, economic growth rate and the tendency to spend at international and national level. Social Environment: In social context, normally Britain customers lean towards a specific product. In every transaction product quality matters a lot, but it could easily be beaten by offering lower pricing of the same brand. Some fresh analysis about Britains customers is that they prefer some fashionable styles over classic trends. This can be seen in Marks Spencers case because they are still struggling to get a bigger market share. This indicates that British buyers are very keen about their wealth. Technological Environment: Now a days a large number of the population is able to use the internet. It means that by using e-commerce many organisations can widen their horizons and do many more operations. This can be seen in foremost companies like Sainsbury, Tesco and ASDA as well. These days most of the trading and purchasing is done through the internet, and it has also become a competitive advantage of Marks and Spencer. Analysis of External Environment of MS: The U.K retail market is very eye-catching. The company has full support from the government. Because Marks Spencer has rich historic values and has become a very powerful organisation in the business world, new competitors are finding it very challenging to keep up with the quality of products and services that Marks Spencer provide. Analysis of the organisations internal environment and identification: In Plan A Marks and Spencer has taken internal analysis, which is also called SWOT analysis. This is a very important part of business development. SWOT analysis is a simple structure for generating strategic alternative from a situation analysis. SWOT is an abbreviation for Strengths, Weaknesses, Opportunities and Threats. In late 1960, Edmund defined SWOT structure. Learned, C. Roland, Christiansen, Kenneth Andrews and William d Goth in Business Policy, Text and Cases (Homewood, IL; Irwin 1969).In the 1980s General Electric Growth Council used this form of analysis. Basically, it throws light on thecompanys strengths weaknesses. The strengths highlight the different aspects that bring results in market value and the weaknesses draw the attention to those areas which need improvements. SWOT analysis is fruitful where you have to tackle a complex situation in a limited time frame. Organisation of an effective strategy is based on a clear definition of the organizations mission. For the success of an organization it requires some necessary ingredients which are listed below: Strategy must be carefully verbalized, applied, manageable and accomplished. Internal analysis of the organisation is an essential part in the strategic planning process. During 2005-06 Marks and Spencer had seventy thousand employees globally. The Company changed the employees structure according to the nature of the customers that used the products and services of Marks Spencer. Marks and Spencer also pledge to promoting equal opportunities regardless of age, disability,race, views about politics, working hours and religion. Marks and Spencer arrange flexible working schedules for fatherhood, adoption and IVF treatment, child and career break to boost their employees uniformity. Marks and Spencer also runs Business Involvement Group (BIG), which is a work demonstration forum in all their stores and offices that inspire their work force to share information and develop discussion about the companys business. If we talk about salary and welfare, the company has some incentive packages that include fundamental fixed pay. As for training, in 2005-06 more than 102,000 days were fixed for training purpose in which Marks and Spencer try to develop inner aptitude and skill of their workers. Marks and Spencer proved that they have great concern about health and safety of their employees by providing a wide range of work related health services. The companys code of ethics is also developing to give guideline to their member concerning their responsibilities towards customers, workers, stockholders, dealers, societies, government and the environment. Identification of the major issues challenging Marks Spencer: Marks and Spencer is one of the UKs biggest traders, giving different services to their customers in the field of food, clothing, and house hold products. They tried at their best level to give good customer service at an affordable price, but it is not always very easy. Marks and Spencer are losing their trend towards the youngstersand their other opponents in the market are taking advantage of this weak point. This is the biggest challenge that Marks and Spencer is facing nowadays. To overcome this weak point Marks and Spencer is also taking steps to provide cheaper products to their customer, but for this they have to import their raw materials, which also lessen the Marks and Spencers image of British Goods Seller. Cards and cash methods have been used for payment since 2001. Marks and Spencer have seen very tough times during the period of recession, but now it seems as though everything is going back to normal. The companys thirteen weeks before the start of OCT (2010) was very hope full. Homeware made an astonishing growth in sales up to 7% and food stuff which was last year 3.6%, this year it increases up to 3.7%.The clothing section is also growing and is the most rapidly expanding sales item of Marks and Spencer. During the autumn the women shoes sales touched a record, which Marks and Spencer claims that it was because of their strong advertisement. External environment and the impact on the strategic direction of the organisation: Strategic direction means those incentives that a company adopts for the achievement of its target i.e. how to produce, develop and sell its products. Basically strategic direction is the planning that an organisation follows for the marketing of its products. Marks and Spencer introduced a plan that they named as PLAN A the purpose behind which is to become worlds most sustainable retailer. For the success of any organisation it is very necessary to keep an eye on the environmental changes that occurs outside the organisation. As these changes affect the strategy of any organisation, it has to alter its rules and regulations according to the environmental changes. There are four main external environmental factors that effect the strategic direction of any organisation. a) Political b) Economic c) Technological d) Social The political condition plays a vital role to put an impact on the strategy of an organisation as it refers to the government policies. If the government introduces new laws and the organisation has some policies or rules and regulations that conflicts with the existing government laws, it has to alter its rules and regulations and make them according to the governments policy. The change in the political condition can affects the strategic direction of the organisation as every government has its own policies and the organisation cannot work against the laws of the country. Economic condition has also a deep effect on the strategic direction of an organisation. The economic condition of any country has a deep rooted effect. It includes taxation rates, economic growth rate and capability to invest at national and international levels. The rapid change in technology is another factor that can affect the strategic direction of an organisation .With the passage of time new techniques and machines are coming up and it is very important to adopt new techniques for the development of a business. In the social environment the consumer plays a vital role to affect on the strategic direction of the organisation. The organisation has to provide the products and services according to the requirements of the consumer. The lifestyle trends, ethical issues, media views, law changes, buying access, brand, religion beliefs, demographics and fashion are the social factors that can affect the strategy of the organisation. What should the organisation do to achieve or maintain competitive advantage in its industries? Competitive advantage: A companys competitive advantages are the features that give permission to do best even in average industry extensive performance and free entry into the industry as a whole. Every company has some definite abilities which make it different from other companies in the same industries. It has some unique competences that cannot be replicated by the opponents. Many companies complete their management price by using effective use of skills to organise their jobs. One example of such a company is Marks and Spencer. This company use technology to locate their goods. The company also use technology to coordinate between different departments. It brings more proficiency and less expenditure, and as a result production cost is low. On -the-counter payment was also introduced by Marks Spencer. It was very beneficial for the company as they need only a small amount of employees, so as a result labour cost was minimized and profit margin were increased. Marks and Spencer with more than 100 years of experience have a competitive advantage over most of their counter parts, because the company earn the trust and reputation among the customers, their workers and suppliers. Their customers have an extensive collection and are fully confident about the companys products and services.They also get value for money as well. Marks and Spencer demonstrates a shared sense of doing things, with their strong inner structure that moves around permanent employment relationships and strong organisational routines. In the external environment Marks and Spencer fully focus on product specification and design to continue their relationship with the customer, which lasts for many years. As part of their business accountability the company has strong conservational and communal responsibilities. TSE Stated that Marks and Spencer use modern methods of management like consumer research, planning, personal management, product innovation, staff training and many more and has proved itself as a founder and outshined among all other companies (1985).Marks Spencer maintain a strong organisational structure that is run by comparatively normal employees who get excellent results over many years, although many changes have occured in the economic environment (1995). Although, over the recent years, due to the big recession the company has had to face downfalls in some of their retailing areas, but they have managed to overcome all their uncertain hurdles through flexibility, that their opponents view as unnerving. According to an analyst Terhi Halme (2008) ,Even though Marks and Spencer has carried out extensive reformation over the past years, the companys competitive advantage has not been fully revived, so the firm could be able to answerable to the current down turn in British retail market. The decline rate during the past few months has been increased in their food unit and as a result revenue has dropped. Because of this, the food sector is also losing its market share. The management have to step up marketing and promotional spending to protect the market share. Additionally the team confidence is also diminish because of changed management, and therefore not been able to generate sustainable improvements. It is possible that Asian and Middle East companies that are in search of western products will take a look at the market shares of Marks and Spencer as presenting buying opportunities at the present price, especially during this recession. Conclusion: Marks and Spencers main aim is to become the worlds most sustainable retailer by 2015. To achieve this target Marks and Spencer introduce Plan A in which it has highlighted five factors to achieve their business goal that is climate change, waste, sustainable raw material, fair partnership and health. There are some internal and external environmental factors that affect the business strategy of the organisation. Internal factors are under the control of the organisation that deals with the strengths and weaknesses. But the external environmental factors are beyond the control of the organisation. Marks and Spencer has also taken initiative to maintain and improve its position. It provides good customer services, using modern techniques, and provides products according to the demand of the customers.

The Similarities And Differences Of Batistas And Castros Affects O :: essays research papers fc

Although it is certain that Fidel Castro and Fulgencio Batista would not have been able to peacefully sit in the same room together, they are alike in more ways than either man would ever have liked to admit. When reviewing the effects they had on Cuban history, many similarities could be noted. At the very start of each man's political career, he overthrew his predecessor using some sort of militant force. In Batista's case, this was achieved by staging a coup with military backing. For Castro, he was a main figurehead in the Cuban Revolution who eventually emerged as Cuba's leader for many years to come. At the onset of both leader's career's as Cuba's leader, Batista and Castro were admired by the majority of the public, but they went on to establish dictatorships and suspended the constitution, thus were later disliked by many.   Ã‚  Ã‚  Ã‚  Ã‚  Both Batista and Castro contributed to the extremism of Cuba's military/political history. As many Cuban leaders had done before him, Fulgencio Batista was part of a militant movement that overthrew his predecessor, Carlos Manuel de Cespedes y Quesada. During this movement, Batista was chief staff of the army, which eventually led to his attaining control of Cuba. In a similar manner, Fidel Castro overthrew Batista. Instead of staging a coup, Castro was the leader of the best organized force of anti-Batista groups during the Cuban Revolution. Because of the guerilla warfare that Castro and other groups were waging against Batista, he eventually resigned from office and fled to the country.   Ã‚  Ã‚  Ã‚  Ã‚  Cuba's political history carries a pattern: when the masses are disillusioned by the current ruler, they turn to a young, strong-willed leader-of-the-people as their new ruler, only to become disillusioned to that ruler when he becomes too oppressive. It has seemed a never- ending cycle. Batista and Castro were both well-regarded leaders initially who appealed strongly to the masses and common citizen. Later, both established dictatorships and lost the support of many of those that they governed. Castro and Batista are each guilt of repression and corruption within their governments. For example, at some point under each regime, the constitution was either suspended or not followed at all. Castro did, though, make one very important contribution to Cuba's political system: Socialism. For the first time, Castro and Che Guevara a socialist plan called the New Man theory which called for developing an ideology amongst citizens that would call for working not for pers onal enrichment, but for social betterment.

Like the Government and Corporations, Man Essay examples -- American S

When I first read the â€Å"The Power Elite† by C. Wright Mills, I saw the title and immediately approached it cautiously. I am a born skeptic, and to me the title conjured images of hippies passing around reefer talking about like, the Illuminati man. However as I read Article 56, chapter 13 of Understanding Society: An Introductory Reader, I was struck by rationally Mills approaches a complex and controversial subject. Particularly effective is his systematic approach of breaking his thesis down into observable facts and logical ideas. â€Å"The Power Elite† begins by defining who or what a power elite is. Mills then examines the crucial areas they dominate as well as the system that exists to support and propagate their influence. He ends by examining the situations that led to the creation of the power elite, how institutions contribute to their formation, and the historical context of the ever increasing concentration of power that has made this status possi ble. As I read this article many passages and ideas seemed to jump out at me. The first is when Mills seeks to define who the power elite are and how they perceive themselves. Mills defines the power elite rather broadly, â€Å"They rule the big corporations, they run the machinery of the state...they direct the military establishment† (Anderson et al. Page 465). However, it is what Mills says next that struck me as particularly poignant. He explains that the power elite do not actually see themselves as particularly powerful. Instead he says that they, â€Å"are uncertain about their roles† and that â€Å"No matter how great their actual power, they tend to be less acutely aware of it than to the resistances of others to its use† ( Anderson et al. Page 465). I find it humorous and some... ...posure of high level politicians, which is still incredibly disproportionate to the amount of influence they have, most of the power elite are unknown outside of the circles of their colleagues and those in the know within their respective fields. In essence, the power elite have had such an influence on pop culture, and their celebrity distractions are so effective, that the general population no longer cares about the huge decisions and possible ramifications that are made for them on a daily basis. One is often left to wonder how much more Fahrenheit 451-ish our society can get. References: Andersen, Margaret et al, comp.Understanding Society: An Introductory Reader. 4th ed.

Biblical Worldview Essay Essay

Introduction/Thesis The Bible’s New Testament book of Romans, chapters 1-8, provides a fundamental perspective and useful resource on how God desires to shape our worldview. A biblical worldview in a society that gravitates to a sinful nature can be a challenge. Paul, however, provides insight that may not encompass every theological truth, but provides the basis of establishing a biblical worldview. Specifically, these chapters provide the essence of how Christians should view the natural world, human identity, human relationships, and culture. The Natural World Paul’s description of a worldview of the natural world is supported in the Bible several times. The book of Genesis begins with God’s creation of the heavens and earth as described in Genesis 1:1. Romans 1:20 also supports God as the master creator by explaining, â€Å"For ever since the world was created, people have seen the earth and sky. Through everything God made, they can clearly see his invisible qualities—his eternal power and divine nature. So they have no excuse for not knowing God.† (NLT) But, because of man’s sinful nature, people turn away from Him and deny His power and divinity. In Romans 1:21-23 Paul states, â€Å"For although they knew God, they neither glorified him as God nor gave thanks to him, but their thinking became futile and their foolish hearts were darkened. Although they claimed to be wise, they became fools and exchanged the glory of the immortal God for images made to look like a mortal human being and birds and animals and reptiles.† (NIV) Despite the evidence of God’s existence, people turned away from Him, worshipped idols, and continued to relish in sin. Human Identity God created man in His image and put mankind over the rest of His creation. In fact, God has ranked man just a little lower than the angels and has anointed us with His glory and honor (Psalms 8:5). So, why is it we have an identity crisis? It is because of sin, we have fallen out of God’s grace. Romans 3:10 states, â€Å"There is no one righteous, not even one.† (NIV) It is through Adam’s sin that we are all now held in God’s contempt. God understands man is bound by his sinful nature. But, Paul describes our  opportunity for redemption in Romans Chapter 8:1-2, â€Å"Therefore, there is now no condemnation for those who are in Christ Jesus, because through Christ Jesus the law of the Spirit who gives life has set you free from the law of sin and death.† (NIV) â€Å"Although the ‘law of sin and death’ is more powerful than our moral will-power, the ‘law of the Spirit of life’ more powerful than the ‘law of sin and death’. It has the power to liberate us.† (DeLashmutt) Through Jesus Christ, we are able to reclaim our human identity as God’s children. Human Relationships Human relationships have been tainted with sin since Adam and Eve. God has provided other human relationships as a gift to us. It’s through these human interactions we demonstrate God’s love through us. Though human nature leans toward sin, especially in dealing with human relationships. Our refusal to acknowledge God will allow us to fulfill our own sinful hearts and desires. These selfish motivations lead us to fulfill the desires of our heart instead of the desires of God’s heart. In Romans 1:18-32, Paul provides a detailed description of the wickedness and immorality of the people. Sin is what separated us from God and a relationship with Him in the first place. God restored this, however, through our gift of salvation in Jesus Christ. Jesus’s life and human relationships, as described in throughout the Gospel, provide a perfect example of the biblical perspective on human relationships. Culture The biblical worldview on culture that Paul describes in Romans is a society that has systematically imploded. Romans 1:26-31 provides explicit detail on the Roman culture at that time. Sin was running rampant through the society. People knew God and they rejected Him anyway. This type of sinful nature and blatant rejection of God spread throughout the culture. (Romans 1:32) People were determined to live in defiance of God and by their own legalistic views of the law. Paul stated that those under the law were lawless because the people abused the law to provide selfish gains or as a means to stand in judgement of another, especially the Gentiles. God meant for the law to be good, but man manipulated it to his own advantage. On the contrary, obedience demonstrates humility. Paul states in Romans 5:19, † For just as through the disobedience of the one man the many were made sinners,  so also through the obedience of the one man the many will be made righteous.† (NIV) The philosophy in this scripture supports God’s desire for us to be the light in the world to shape our culture for His purpose and not our own. Paul maintains that the grace that we as Christians are under was achieved by one Man’s (Jesus’) righteous act (Rom. 5:18). (McCracken) Conclusion I believe that Paul’s epistle is just as relevant today and it was in his time. Paul’s thoughts and insight provide sound perspective for biblical worldviews for believers to mature in their faith. These biblical worldviews about our natural world, human identity, human relationship and culture are applicable to current believers because human nature has not changed. These messages are just as relevant to us today because there is still sin in the world that will not end until the Second Coming of Christ. In the meantime, we can use Romans 1-8 as a guide to align our biblical worldviews with God’s heart. Paul’s perspective on biblical worldviews, such as these, are just one of the many gems we can get from the Word. References DeLashmutt, G. Walking by the Spirit Part 1. Teaching Series from Romans.

Social Media :: Curse or Blessing ?

Social Media :: Curse or blessing ? The way I see it, it all depends on how these sites, like Facebook or Twitter, are being used. Social media itself can be abused, overused, and taken advantage of. However, the power of social media itself is probably greater than the power of any person, any novel, any ruler, or even any country. But, whether that incredible power is a blessing or a curse is also one matter to question. The power of social media can be something extremely influential. This first took a huge toll in the beginning of 2011 with the political upheaval of Egypt.The Internet's far-reaching speed combined with social media websites to create something unforgettable. The voices of Egypt stood together to overthrow the regime of Egyptian President Hosni Mubarak, and they spread all throughout the world. The power of social media was also noted when Mexicans turned to it for survival, not too long ago. At first, this served as a revolution. For the very first time, people's voices and opinions were coming together to form something larger than themselves. But we have to wonder, is that power too much?History has repeated itself in telling us that it becomes a problem when one voice has too much power. One only needs to look at people like Hitler, Idi Amin, and Mao Zong for proof that giving one voice too much power can sink an entire people or nation. And in Egypt, this corrupting nature of power turned itself over from the ruler to the subjects which resulted in the same horrific effect. From this, it is clear that social media has a way of lending itself to this attribute of power. Another way social media can act as a curse is through its changing the behavior of our society.Some say social media sites can lend to shorter attentions and less efficient work. Not only that, but my generation, that is, teenagers, tends to abuse social media and use it for popularity. Despite social media being a term with the connotation of connecting us, that seems t o be one thing it is doing least. People who abuse Facebook, for example, by requesting and accepting as many ‘friends' as possible, up to thousands, are giving those relationships artificial traits. Those relationships are so scattered and insignificant that many people don't even know some of their ‘friends. These thinning relationships have no such value, and are illusions of genuine relationships. In this abuse of social media, values of building relationships and making new connections, as were the intentions of social media, are taken away and transformed wrongfully. Nevertheless, many people do use social media for positive purposes, which leads me to the side of social media that is a complete blessing to this modern world. When used correctly, the benefits of social media can far outweigh some of its downfalls. Social media changes the world every day, in ways both small and large.For everyone who uses it, social media at least promotes and encourages communicat ion and lends to more modern ways of learning and communicating. Not only do they lend to more efficiency in our rapidly evolving technologically advanced society, but social media sites are also some of the best ways to positively influence people by sharing your opinions. They act as platforms for your voice. If you have great ideas or want to be heard or found, websites like Google+, Twitter, and LinkedIn can promote those good intentions.Through these sites, you can find millions of people who share the same interests as you, and start making a difference, step by step. Social media websites can operate as both curses and blessings in our modern society. The difference between it as a curse and a blessing all hangs on the shoulders of its users. You may choose to abuse the potential of Facebook, or to change the world with Twitter. The difference in your actions may be small, but the end result varies greatly, and it is up to you to decide social media's role in your life.
