Promotion Mix To Create An IMC Campaign Marketing Essay Essay Example

Promotion Mix To Create An IMC Campaign Marketing Essay Paper As defined by the American Association of Advertising Agencies, integrated selling communications ( IMC ) is a construct of marketing communications be aftering that recognizes the added value of a comprehensive program ( Elliott, 2012, P:491 ) . Companies that sell merchandises or services use some or all of the constituents of a selling and communications mix, besides called a promotional mix. These include advertisement, personal gross revenues, gross revenues publicities, public dealingss and direct selling. Most national trade names use all parts of the mix, each in proportion to the demands of the merchandise. Cereal shapers, for illustration, concentrate most attempts and money on advertisement and gross revenues publicities, such as vouchers. Other merchandises call for different mix ratios, with some mix constituents wholly eschewed. We will write a custom essay sample on Promotion Mix To Create An IMC Campaign Marketing Essay specifically for you for only $16.38 $13.9/page Order now We will write a custom essay sample on Promotion Mix To Create An IMC Campaign Marketing Essay specifically for you FOR ONLY $16.38 $13.9/page Hire Writer We will write a custom essay sample on Promotion Mix To Create An IMC Campaign Marketing Essay specifically for you FOR ONLY $16.38 $13.9/page Hire Writer In add-on to these cardinal promotional tools, the seller can besides utilize other techniques, such as exhibitions and merchandise arrangement in films, vocals or picture games, which have been turning in popularity in recent old ages. Before continuing any farther, nevertheless, it is of import to emphasize that promotional mix determinations should non be made in isolation. As we saw with pricing, all facets of the selling mix demand to be blended together carefully. The promotional mix used must be aligned with the determinations made with respect to merchandise, pricing and distribution, in order to pass on benefits to a mark market. But for a soft-drinks shaper like Pepsi, IMC can besides be used can be used to make more communicating impact, e.g. Ad can be combined with gross revenues publicities and a small spot of public dealingss such as sponsorship/events. From the facts of the instance survey, Pepsi used a new attack in its selling communicating. Pepsi holds the figure one, 3rd and 4th place among music, overall place among all companies, and amusement channels. It gives a important part on the music channels with 12.81 % portion of coverage and holds the first place in that class. It has the 3rd place on the whole Television media with overall 4.29 % portion of coverage, the effectivity of which is reported in decrease by research workers ( Kotler A ; Keller 2006, p.576 ) . Similarly, it comes at figure 4th on amusement channels. Overall, these new media win the trust of consumers by linking with them at a deeper degree. Sellers are taking note of many different societal media chances and get downing to implement new societal enterprises at a higher rate than of all time before. Social media selling and the concerns that utilize it have become more sophisticated. Q2. How efficaciously has Pepsi integrated digital and traditional media for the publicity of their merchandises? Provide examples of digital media used. Nowadays 1000000s of consumers converse on a day-to-day footing in on-line communities, treatment forums, web logs and societal webs. They turn to the Internet to portion sentiments, advice, grudges and recommendations. It has been said that traditional media is losing its face value and that the Internet is a craze and digital merely applies to the millenary coevals. While that may look true, if you want to remain on the advanced cusp for your concern, utilize both traditional and internet media selling and here are some grounds why: 1. On-line conversations can power or deflate a company s trade name. Do you hold a presence? 2. Discover specific issues that are being discussed around your company, trade name or organisation and make feedback to these issues. 3. There may be events, tendencies and issues that may be act uponing industry and trade name bombilation. 4. Measure how your online and offline selling runs resonate with consumers. 5. Leverage viva-voce to drive trade name credibleness, and finally gross revenues if you use face-to-face selling, Internet Marketing, Search Engine Optimization Strategy, and Social Media Strategy right. Peoples are more likely to pass on through both viva-voce and societal media when they are engaged with the merchandise, service, or thought. This battle may come of course for protagonists of causes, political campaigners, and voguish new technological merchandises. However, it can besides be creatively stimulated for merchandises and services which generate less psychological engagement of clients. For illustration, Pepsi ( 2008 ) uses its Pepsi Stuff online client trueness plan to prosecute consumers by enabling them to deliver points for MP3 downloads, telecasting show downloads, Cadmiums, DVDs, electronics, and dress. Political campaign participants are besides allowed to take part in sweepstakes drawings for larger awards, such as place theatre systems and trip giveaways. Coca Cola ( 2008 ) has a similar run entitled My Coke Rewards. Harmonizing to Nielson research, Television users watch more than of all time before ( an norm of 127 hour, 15 min per month ) and these users are passing 9 % more clip utilizing the Internet ( 26 hour, 26 min per month ) from last twelvemonth. Approximately 220 million Americans have Internet entree at place and/or work with a turning figure utilizing the Internet for research and societal media. Knowing this research, traditional media entertains and communicates to a mass audience whereas digital media entertains, communicates with, and engages the person. The benefits of digital media can be extremely mensurable and sellers can frequently see a direct consequence in the signifier of improved gross revenues in add-on to set uping a direct nexus with the consumer. This can besides be cost effectual. However, the booby traps of digital selling can be that the medium is new, invariably altering and germinating with consequences that vary. You frequently acquire what you ask for! Digital media is known as digitized content ( text, artworks, sound and picture ) that can be transmitted over the Internet. While digital media ingestion such as chirrup, facebook, youtube etc have increased enormously, Pepsi can non disregard consumers who still rely on traditional media for their enlightening and amusement demands, as a consequence, 2/3 of their advertisement budget is still dedicated to traditional media. Sellers must strike a good balance between utilizing traditional and digital/social media and other promotional tools Q3. How might Pepsi step the effectivity of its new run? Provide examples. The most suited standards for measuring the effectivity of advertisement, depends on a figure variables, such as the advertisement ends, the type of media used, the cost of rating, the value that the concern or advertisement bureau topographic points on rating steps, the degree of preciseness and dependability required, who the rating is for and the budget. It is hard to accurately mensurate the effectivity of a peculiar advertizement, because it is affected by such things as the sum and type of anterior advertisement The best measuring of a run s effectivity is its ability to run into its aims. From the instance survey, Pepsi s aims could be: Attract more rival s users ( such as Coca-Cola ) Increase gross revenues volume Hold present Customers Create trade name consciousness To project a rejuvenated image for Pepsi as a socially responsible corporation To alter consumer attitudes from impersonal or unfavorable ( it is a soft drink after all ) to positive To utilize newer, digital media to prosecute in bipartisan communicating with their customers/public. To pass on its new image via it new packaging By and large, Pepsi could utilize the followers to mensurate the run s effectivity: Stimulate an addition in gross revenues Remind clients of the being of a merchandise Inform clients Construct a trade name image Build client trueness and relationship Change client attitudes Sellers recognize that in the modern universe of selling there are many different chances and methods for reaching current and prospective clients to supply them with information about a company and/or trade names. The challenge is to understand how to utilize the assorted IMC tools to do such contacts and present the stigmatization message efficaciously and expeditiously. A successful IMC plan requires that sellers find the right combination of communicating tools and techniques, define their function and the extent to which they can or should be used, and organize their usage. To carry through this, the individuals responsible for the company s communicating attempts must hold an apprehension of the IMC tools that are available and the ways they can be used.

Mass Spectrometry - What It Is and How It Works

Mass Spectrometry - What It Is and How It Works Mass spectrometry (MS) is an analytical laboratory technique to separate the components of a sample by their mass  and electrical charge. The instrument used in MS is called mass spectrometer. It produces a mass spectrum that plots the mass-to-charge (m/z) ratio of compounds in a mixture. How a Mass Spectrometer Works The three main parts of a mass spectrometer are the ion source, the mass analyzer, and the detector. Step 1: Ionization The initial sample may be a solid, liquid, or gas. The sample is vaporized into a gas and then ionized by the ion source, usually by losing an electron to become a cation. Even species that normally form anions or dont usually form ions are converted to cations (e.g., halogens like chlorine and noble gases like argon). The ionization chamber is kept in a vacuum so the ions that are produced can progress through the instrument without running into molecules from air. Ionization is from electrons that are produced by heating up a metal coil until it releases electrons. These electrons collide with sample molecules, knocking off one or more electrons. Since it takes more energy to remove more than one electron, most cations produced in the ionization chamber carry a 1 charge. A positive-charged metal plate pushes the sample ions to the next part of the machine. (Note: Many spectrometers work in either negative ion mode or positive ion mode, so its important to know the setting in order to analyze the data.) Step 2: Acceleration In  the mass analyzer, the ions are then accelerated through a potential difference and focused into a beam. The purpose of acceleration is to give all species the same kinetic energy, like starting a race with all runners on the same line. Step 3: Deflection The ion beam passes through a magnetic field which bends the charged stream. Lighter components or components with more ionic charge will deflect in the field more than heavier or less charged components. There are several different types of mass analyzers. A time-of-flight (TOF) analyzer accelerates ions to the same potential and then determines how long is needed for them to hit the detector. If the particles all start with the same charge, the velocity depends on the mass, with lighter components reaching the detector first. Other types of detectors measure not only how much time it takes for a particle to reach the detector, but how much it is deflected by an electric and/or magnetic field, yielding information besides just mass. Step 4: Detection A detector counts the number of ions at different deflections. The data is plotted as a graph or spectrum  of different masses. Detectors work by recording the induced charge or current caused by an ion striking a surface or passing by. Because the signal is very small, an electron multiplier, Faraday cup, or ion-to-photon detector may be used. The signal is greatly amplified to produce a spectrum. Mass Spectrometry Uses MS is used for both qualitative and quantitative chemical analysis. It may be used to identify the elements and isotopes of a sample, to determine the masses of molecules, and as a tool to help identify chemical structures. It can measure sample purity and molar mass. Pros and Cons A big advantage of mass spec over many other techniques is that it is incredibly sensitive (parts per million). It is an excellent tool for identifying unknown components in a sample or confirming their presence. Disadvantages of mass spec are that it isnt very good at identifying hydrocarbons that produce similar ions and its unable to tell optical and geometrical isomers apart. The disadvantages are compensated for by combining MS with other techniques, such as gas chromatography (GC-MS).

In Chitra Banerjee Divakaruni's short story, Clothes (page 533), Essay

In Chitra Banerjee Divakaruni's short story, Clothes (page 533), Sumita, the protagonist, comes to America where she exp - Essay Example Conflicts in the Life of Sumita Culminated through the Symbolic Scheme Chitra Banerjee Divakaruni’s fictions are generally set against the background of India or in America and mostly they centre round the experiences of the South Asian immigrants especially the women. The story â€Å"Clothes† is not an exception in this regard. The story presents the transition that the protagonist, Sumita undergoes in her life. The story revolves round the transition of Sumita from a young girl to a woman; from woman to a wife and finally facing the climax and the predicament in her life by being a widow. Sumita accepts the tradition of her society and accepts the concept of arranged marriage and marries a man whom she has never met before. She accepts the fact and is shown at the outset of the story to explore the unexplored and know the unknown and with this vision; she whole heartedly starts dreaming of her new life which is going to place her to a complete different socio-cultural milieu. She undergoes a paradoxical transition in her life and that evolves at different times through her clothes and their colours (Almeida, â€Å"The politics of mourning: Grief Management in Cross-cultural Fiction†). Conflict essentially builds up and strengthens the dramatic qualities of any fiction and that conflict does not necessarily mean a conflict with an antagonist in its physical form. The antagonist as in the case is society and the cross cultural transition which treats the existential discourse of the protagonist. Sumita in the US faces difficulty to adept complete change in her attire from eastern styling to that of western. The conflict which she faces is from the transition that she undergoes while changing her identity from wife to a women. One of those dresses includes a T-shirt which is orange in color and symbolizes hope and change on a brighter note. But the destined predicament at the last segment of the story where Sumita has to encounter an unfortu nate incident in the face of her husband’s murder washes all sort of colour and possibility in her life and places her with a confrontation of uncertainty where she is confused to continue her life in a country where the life of her husband was not secured even or get back to the soil i.e. her country from where she was uprooted long back as she fails to identify herself in both the nations and their societies. This is probably the greatest threat encountered by the protagonist of Chitra Banerjee Divakaruni’s short story, â€Å"Clothes† presented in the form of diasporas of existential and identity crisis from the perspective of feminist discourse. Transition in Sumita’s life does not only take place at physical plane but it takes place also mentally. Quite natural to the human nature, it gets reflected through the outward appearance of Sumita precisely through her clothes and its colours. The Indian traditional attire for women is Sari and Sumita at the beginning of the story is seen clad in it fully at one with the tradition of her soil. The selection of each cloth in the story and its colour has a purpose. The story begins with a stage in Sumita’s life when she is about to be a bride and puts a yellow sari, all set to meet her prospective

The history and development of freehold property title in english Essay

The history and development of freehold property title in english system - Essay Example There were three aspects of feudalism such as personal, property, monarchial control. Under this system, the kings had rights but also had to perform responsibilities under feudalistic societal norms Over time, it was seen that the monarch was responsible for giving fiefs to knights for military services rendered to him. The king was also responsible for the upkeep of land since he had only parted with possession and not ownership which still vested with the Crown. Thus it could be seen that in the 10th century, the kings exercised tremendous control and patronage over land, and granted its use as payment for military services rendered by his knights and military personnel. For the first time in English history, William claimed eventual control of virtually all the land in England and asserted the right to dispose of it as he deemed necessary. Henceforth, all land was owned by the King. At the initial stages, King William appropriated the lands of all English lords who were killed during war and fiefed them to his Norman soldiers and supporters. These initial approbations led to revolts, which resulted in more seizures which moved along unabated for five years after Battle of Hastings. Even after he managed to quell rebellions, William the Conqueror continued to exercise their domain and supremacy of Normans over the country. His influences was so extensive that if the event an England landlord died without any children, the King or his barons, could choose a heir for the dead man’s properties and successor from Normandy. He exercised control over properties by encouraging marriages to Normans, which resulted in the ultimate takeover of English aristocracy by Normans. The system enunciated by William has impacted even modern day property holdings in England. The land belongs to the Crown and no individual or private holdings may be enforceable. Even

Economic Effects of Water Pollution Essay Example | Topics and Well Written Essays - 2750 words

Economic Effects of Water Pollution - Essay Example In modern times, organic pollution has been on an upward trend to the environment and this is heavy because of the growing population the world is witnessing. One will find in a developed city, that there are so many people that the environment sewerage plants and sewerage plants are not able to take in all the waste and at the same time, function in its usual way. The excess waste becomes food for the algae and this increases their growth rate and thus depletes oxygen in the water. In order to combat diseases and combat the extinction of plant and animal life, which play a big part in the economy, water pollution should be put under control. It has been estimated that it is the lead cause of deaths and diseases in the world. To control water pollution steps need to be taken like the treatment of domestic sewage, which apparently contains 99.9% of pure water, industrial wastewater treatment, done through pollution prevention process, agricultural wastewater treatment through point and non-point source control system and many other ways. This proposal aims at looking at the various ways that can be used to prevent water pollution and to establish the ways that are most efficient and economically viable. This will be done by clearly looking at all the methods that can be used to prevent water pollution and their workability. ... point source pollution and the non-point source pollution, the causes i.e. pathogens, chemical and other contaminants, thermal pollution and also to look into details the different methods that are used to reduce or eliminate water pollution i.e. domestic sewage, industrial wastewater, agricultural wastewater, construction site stormwater, urban runoff (Parks, 2007). During the summer of 1971, at a filtration plant in Chicago south, the filters were blocked with a lot of algae that they had to be removed by hand. The water tasted and smelled like dead fish and this led to the addition of a lot more chlorine in order for the water to be drinkable.

Weather Forecasting with Digital Signals

Weather Forecasting with Digital Signals INTRODUCTION: Digital signal processing (DSP) is concerned with the representation of the signals by a sequence of numbers or symbols and the processing of these signals. Digital signal processing and analog signal processing are subfields of signal processing. The analog waveform is sliced into equal segments and the waveform amplitude is measured in the middle of each segment. The collection of measurements makes up the digital representation of the waveform. Converting a continuously changing waveform (analog) into a series of discrete levels (digital) Applications of DSP DSP technology is nowadays commonplace in such devices as mobile phones, multimedia computers, video recorders, CD players, hard disc drive controllers and modems, and will soon replace analog circuitry in TV sets and telephones. An important application of DSP is in signal compression and decompression. Signal compression is used in digital cellular phones to allow a greater number of calls to be handled simultaneously within each local cell. DSP signal compression technology allows people not only to talk to one another but also to see one another on their computer screens, using small video cameras mounted on the computer monitors, with only a conventional telephone line linking them together. In audio CD systems, DSP technology is used to perform complex error detection and correction on the raw data as it is read from the CD. some of the mathematical theory underlying DSP techniques, such as Fourier and Hilbert Transforms, digital filter design and signal compression, can be fairly complex, the numerical operations required actually to implement these techniques are very simple, consisting mainly of operations that could be done on a cheap four-function calculator. The architecture of a DSP chip is designed to carry out such operations incredibly fast, processing hundreds of millions of samples every second, to provide real-time performance: that is, the ability to process a signal live as it is sampled and then output the processed signal, for example to a loudspeaker or video display. All of the practical examples of DSP applications mentioned earlier, such as hard disc drives and mobile phones, demand real-time operation.

Since lives and livelihoods depend on accurate weather forecasting, these improvements have helped not only the understanding of weather, but how it affects living and nonliving things on Earth. Weather forecasting is the application of science and technology to predict the state of the atmosphere for a future time and a given location. Human beings have attempted to predict the weather informally for millennia, and formally since at least the nineteenth century. Weather forecasts are made by collecting quantitative data about the current state of the atmosphere and using scientific understanding of atmospheric processes to project how the atmosphere will evolve. Once an all-human endeavor based mainly upon changes in barometric pressure, current weather conditions, and sky condition, forecast models are now used to determine future conditions. Human input is still required to pick the best possible forecast model to base the forecast upon, which involves pattern recognition skills, teleconnections, knowledge of model performance, and knowledge of model biases. The chaotic nature of the atmosphere, the massive computational power required to solve the equations that describe the atmosphere, error involved in measuring the initial conditions, and an incomplete understanding of atmospheric processes mean that forecasts become less accurate as the difference in current time and the time for which the forecast is being made (the range of the forecast) increases. The use of ensembles and model consensus help narrow the error and pick the most likely outcome. There are a variety of end uses to weather forecasts. Weather warnings are important forecasts because they are used to protect life and property. Forecasts based on temperature and precipitation are important to agriculture, and therefore to traders within commodity markets. Temperature forecasts are used by utility companies to estimate demand over coming days. On an everyday basis, people use weather forecasts to determine what to wear on a given day. Since outdoor activities are severely curtailed by heavy rain, snow and the wind chill, forecasts can be used to plan activities around these events, and to plan ahead and survive them. History of weather control If we dispense with legends, at least Native American Indians had methods which they believed to induce rain. The Finnish people, on the other hand, were believed by others to be able to control all weather. Thus Vikings refused to take Finns on their raids by sea. Remnants of this belief lasted well into the modern age, with many ship crews being reluctant to accept Finnish sailors. The early modern era saw people observe that during battles the firing of cannons and other firearms often precipitated precipitation. The first example of weather control which is still considered workable is probably the lightning conductor. For millennia people have tried to forecast the weather. In 650 BC, the Babylonians predicted the weather from cloud patterns as well as astrology. In about 340 BC, Aristotle described weather patterns in Meteorologica. Later, Theophrastus compiled a book on weather forecasting, called the Book of Signs. Chinese weather prediction lore extends at least as far back as 300 BC. In 904 AD, Ibn Wahshiyyas Nabatean Agriculture discussed the weather forecasting of atmospheric changes and signs from the planetary astral alterations; signs of rain based on observation of the lunar phases; and weather forecasts based on the movement of winds. Ancient weather forecasting methods usually relied on observed patterns of events, also termed pattern recognition. For example, it might be observed that if the sunset was particularly red, the following day often brought fair weather. This experience accumulated over the generations to produce weather lore. However, not all of these predictions prove reliable, and many of them have since been found not to stand up to rigorous statistical testing. It was not until the invention of the electric telegraph in 1835 that the modern age of weather forecasting began. Before this time, it had not been possible to transport information about the current state of the weather any faster than a steam train. The telegraph allowed reports of weather conditions from a wide area to be received almost instantaneously by the late 1840s. This allowed forecasts to be made by knowing what the weather conditions were like further upwind. The two men most credited with the birth of forecasting as a scienc e were Francis Beaufort (remembered chiefly for the Beaufort scale) and his protà ©gà © Robert FitzRoy (developer of the Fitzroy barometer). Both were influential men in British naval and governmental circles, and though ridiculed in the press at the time, their work gained scientific credence, was accepted by the Royal Navy, and formed the basis for all of todays weather forecasting knowledge. To convey information accurately, it became necessary to have a standard vocabulary describing clouds; this was achieved by means of a series of classifications and, in the 1890s, by pictorial cloud atlases. Great progress was made in the science of meteorology during the 20th century. The possibility of numerical weather prediction was proposed by Lewis Fry Richardson in 1922, though computers did not exist to complete the vast number of calculations required to produce a forecast before the event had occurred. Practical use of numerical weather prediction began in 1955, spurred by the development of programmable electronic computers. * Modern aspirations There are two factors which make weather control extremely difficult if not fundamentally intractable. The first one is the immense quantity of energy contained in the atmosphere. The second is its turbulence. Effective cloud seeding to produce rain has always been some 50 years away. People do utilize even the most expensive and experimental types of it, but more in hope than confidence. Another even more speculative and expensive technique that has been semiseriously discussed is the dissipation of hurricanes by exploding a nuclear bomb in the eye of the storm. It is questionable that it will ever even be tried, because if it failed, the result would be a hurricane bearing radioactive fallout along with the destructive power of its winds and rain. * Modern day weather forecasting system Components of a modern weather forecasting system include: Data collection Data assimilation Numerical weather prediction Model output post-processing Forecast presentation to end-user * Data collection Observations of atmospheric pressure, temperature, wind speed, wind direction, humidity, precipitation are made near the earths surface by trained observers, automatic weather stations or buoys. The World Meteorological Organization acts to standardize the instrumentation, observing practices and timing of these observations worldwide. Stations either report hourly in METAR reports, or every six hours in SYNOP reports. Diurnal (daily) rhythm of air pressure in northern Germany (black curve is air pressure) Atmospheric pressure is the pressure at any point in the Earths atmosphere. For other uses, see Temperature (disambiguation). An AWS in Antarctica An automatic weather station (AWS) is an automated version of the traditional weather station, either to save human labour or to enable measurements from remote areas. Weather buoys are instruments which collect weather and ocean data within the worlds oceans. WMO flag The World Meteorological Organization (WMO, French: , OMM) is an intergovernmental organization with a membership of 188 Member States and Territories. METAR (for METeorological Aerodrome Report) is a format for reporting weather information. SYNOP (surface synoptic observations) is a numerical code (called FM-12 by WMO) used for reporting marine weather observations made by manned and automated weather stations. Measurements of temperature, humidity and wind above the surface are found by launching radiosondes (weather balloon). Data are usually obtained from near the surface to the middle of the stratosphere, about 30,000 m (100,000 ft). In recent years, data transmitted from commercial airplanes through the AMDAR system has also been incorporated into upper air observation, primarily in numerical models. radiosonde with measuring instruments A radiosonde (Sonde is German for probe) is a unit for use in weather balloons that measures various atmospheric parameters and transmits them to a fixed receiver. Rawinsonde weather balloon just after launch. Atmosphere diagram showing stratosphere. Aircraft Meteorological Data Relay (AMDAR) is a program initiated by the World Meteorological Organization. Increasingly, data from weather satellites are being used due to their (almost) global coverage. Although their visible light images are very useful for forecasters to see development of clouds, little of this information can be used by numerical weather prediction models. The infra-red (IR) data however can be used as it gives information on the temperature at the surface and cloud tops. Individual clouds can also be tracked from one time to the next to provide information on wind direction and strength at the clouds steering level. Polar orbiting satellites provide soundings of temperature and moisture throughout the depth of the atmosphere. Compared with similar data from radiosondes, the satellite data has the advantage that coverage is global, however the accuracy and resolution is not as good. A weather satellite is a type of artificial satellite that is primarily used to monitor the weather and/or climate of the Earth. Sounding The historical nautical term for measuring dept h. Meteorological radar provide information on precipitation location and intensity.. Additionally, if a Pulse Doppler weather radar is used then wind speed and direction can be determined.. * Data assimilation Data assimilation (DA) is a method used in the weather forecasting process in which observations of the current (and possibly, past) weather are combined with a previous forecast for that time to produce the meteorological `analysis; the best estimate of the current state of the atmosphere. Weatherman redirects here. Modern weather predictions aid in timely evacuations and potentially save lives and property damage. More generally, Data assimilation is a method to use observations in the forecasting process. In weather forecasting there are 2 main types of data assimilation: 3 dimensional (3DDA) and 4 dimensional (4DDA). In 3DDA only those observations are used available at the time of analyses. In 4DDA the past observations are included (thus, time dimension added). The first data assimilation methods were called the objective analyses (e.g., Cressman algorithm). This was in contrast to the subjective analyses, when (in the past practice) numerical weather predictions (NWP) forecasts were arbitrarily corrected by meteorologists. The objective methods used simple interpolation approaches, and thus were the kind of 3DDA methods. The similar 4DDA methods, called nudging also exist (e.g. in MM5 NWP model). They are based on the simple idea of Newtonian relaxation. The idea is to add in the right part of dynamical equations of the model the term, proportional to the difference of the calculated meteorological variable and the observation value. This term, that has a negative sign keeps the calculated state vector closer to the observations. The first breakdown in the field of data assimilation was introducing by L.Gandin (1963) with the statistical interpolation (or optimal interpolation ) method. It developed the previous ideas of Kolmogorov. That method is the 3DDA method and is the kind of regression analyses, which utilizes the information about the spatial distributions of covariance functions of the errors of the first guess field (previous forecast) and true field. These functions are never known. However, the different approximations were assumed. In fact optimal interpolation algorithm is the reduced version of the Kalman filtering (KF) algorithm, when the covariance matrices are not calculated from the dynamical equations, but are pre-determined in advance. The Kalman filter (named after its inventor, Rudolf Kalman) is an efficient recursive computational solution for tracking a time-dependent state vector with noisy equations of motion in real time by the least-squares method. When this was recognised the attempts to introduce the KF algorithms as a 4DDA tool for NWP models were done. However, this was (and remains) a very difficult task, since the full version of KF algorithm requires solution of the enormous large number of additional equations. In connection with that the special kind of KF algorithms (suboptimal) for NWP models were developed. Another significant advance in the development of the 4DDA methods was utilizing the optimal control theory (variational approach) in the works of Le Dimet and Talagrand, 1986, based on the previous works of G. Marchuk. The significant advantage of the variational approaches is that the meteorological fields satisfy the dynamical equations of the NWP model and at the same time they minimize the functional, characterizing their difference from observations. Thus, the problem of constrained minimization is solved. The 3DDA variational methods also exist (e.g., Sasaki, 1958). Optimal control theory is a mathematical field that is concerned with control policies that can be deduced using optimization algorithms. As it was shown by Lorenc, 1986, the all abovementioned kinds of 4DDA methods are in some limit equivalent. I.e., under some assumptions they minimize the same cost functional. However, these assumptions never fulfill. The rapid development of the various data assimilation methods for NWP is connected to the two main points in the field of numerical weather prediction: 1. Utilizing the observations currently seems to be the most promicing challange to improve the quality of the forecasts at the different scales (from the planetary scale to the local city, or even street scale) 2. The number of different kinds of observations (sodars, radars, sattelite) is rapidly growing. The DA methods are currently used not also in weather forecasting, but in different environmental forecasting problems, e.g. in hydrological forecasting. Basically the same types of DA methods, as those, described above are in use there. Data assimilation is the challange for the every forecasting problem. Numerical weather prediction Numerical weather prediction is the science of predicting the weather using mathematical models of the atmosphere. Manipulating the huge datasets and performing the complex calculations necessary to do this on a resolution fine enough to make the results useful can require some of the most powerful supercomputers in the world.

Geopotential height is a vertical coordinate referenced to Earths mean sea level an adjustment to geomet ric height (elevation above mean sea level) using the variation of gravity with latitude and elevation. Weather is a term that encompasses phenomena in the atmosphere of a planet. A mathematical model is an abstract model that uses mathematical language to describe the behaviour of a system. A supercomputer is a computer that leads the world in terms of processing capacity, particularly speed of calculation, at the time of its introduction. An example of 500 mbar geopotential height prediction from a numerical weather prediction model Model output post processing The raw output is often modified before being presented as the forecast. This can be in the form of statistical techniques to remove known biases in the model, or of adjustment to take into account consensus among other numerical weather forecasts. For other senses of this word, see bias (disambiguation). In the past, the human forecaster used to be responsible for generating the entire weather forecast from the observations. However today, for forecasts beyond 24hrs human input is generally confined to post-processing of model data to add value to the forecast. Humans are required to interpret the model data into weather forecasts that are understandable to the end user. Additionally, humans can use knowledge of local effects which may be too small in size to be resolved by the model to add information to the forecast. However, the increasing accuracy of forecast models continues to decrease the need for post-processing and human input. Examples of weather model data can be found on Vigilant Weathers Model Pulse. Presentation of weather forecasts The final stage in the forecasting process is perhaps the most important. Knowledge of what the end user needs from a weather forecast must be taken into account to present the information in a useful and understandable way. * Public information One of the main end users of a forecast is the general public. Thunderstorms can cause strong winds, dangerous lightning strikes leading to power outages, and widespread hail damage. Heavy snow or rain can bring transportation and commerce to a stand-still, as well as cause flooding in low-lying areas. Excessive heat or cold waves can kill or sicken those without adequate utilities. The National Weather Service provides forecasts and watches/warnings/advisories for all areas of the United States to protect life and property and maintain commercial interests. Traditionally, television and radio weather presenters have been the main method of informing the public, however increasingly the internet is being used due to the vast amount of information that can be found. * Air traffic The aviation industry is especially sensitive to the weather. Fog and/or exceptionally low ceilings can prevent many aircraft landing and taking off. Similarly, turbulence and icing can be hazards whilst in flight. Thunderstorms are a problem for all aircraft, due to severe turbulence and icing, as well as large hail , strong winds, and lightning , all of which can cause fatal damage to an aircraft in flight. On a day to day basis airliners are routed to take advantage of the jet stream tailwind to improve fuel efficiency. Air crews are briefed prior to take off on the conditions to expect en route and at their destination. * Utility companies Electricity companies rely on weather forecasts to anticipate demand which can be strongly affected by the weather. In winter, severe cold weather can cause a surge in demand as people turn up their heating. Similarly, in summer a surge in demand can be linked with the increased use of air conditioning systems in hot weather. * Private sector Increasingly, private companies pay for weather forecasts tailored to their needs so that they can increase their profits. For example, supermarket chains may change the stocks on their shelves in anticipation of different consumer spending habits in different weather conditions. a) =Ensemble forecasting= Although a forecast model will predict realistic looking weather features evolving realistically into the distant future, the errors in a forecast will inevitably grow with time due to the chaotic nature of the atmosphere. The detail that can be given in a forecast therefore decreases with time as these errors increase. There becomes a point when the errors are so large that the forecast is completely wrong and the forecasted atmospheric state has no correlation with the actual state of the atmosphere. However, looking at a single forecast gives no indication of how likely that forecast is to be correct. Ensemble forecasting uses lots of forecasts produced to reflect the uncertainty in the initial state of the atmosphere (due to errors in the observations and insufficient sampling). The uncertainty in the forecast can then be assessed by the range of different forecasts produced. They have been shown to be better at detecting the possibility of extreme events at long range. Ensemble forecasts are increasingly being used for operational weather forecasting (for example at ECMWF , NCEP , and the Canadian forecasting center). b) =Nowcasting= The forecasting of the weather in the 0-6 hour timeframe is often referred to as nowcasting . It is in this range that the human forecaster still has an advantage over computer NWP models. In this time range it is possible to forecast smaller features such as individual shower clouds with reasonable accuracy, however these are often too small to be resolved by a computer model. A human given the latest radar, satellite and observational data will be able to make a better analysis of the small scale features present and so will be able to make a more accurate forecast for the following few hours. Signal Processing Generating imagery for forecasting terror threats Intelligence analysts and military planners need predictions about likely terrorist targets in order to better plan the deployment of security forces and sensing equipment. We have addressed this need using Gaussian-based forecasting and uncertainty modeling. Our approach excels at indicating the highest threats expected for each point along a travel path and for a global war on terrorism mission. It also excels at identifying the greatest-likelihood collection areas that would be used to observe a target. 1 on geospatial analysis and asymmetric-threat forecasting in the urban environment. He showed how to extract distinct signatures from associations made between historical event information and contextual information sources such as geospatial and temporal political databases. We have augmented this to include uncertainty estimates associated with historical events and geospatial information layers.2 Event Forecasting Spatial Preferences The notion of spatial preferences has been used to find potential crime1 and threat3 hot spots. The premise is that a terrorist or criminal is directed toward a certain location by a set of qualities, such as geospatial features, demographic and economic information, and recent political events. Focusing on geospatial information, we assume the intended target is associated with features a small distance from the event location. We assign the highest likelihoods to the distances between each key feature and the event, and taper them away from these distances. This behavior is modeled using a kernel function centered at each of these distances. For a Gaussian kernel applied to a discretized map, the probability density function à Ã‚  for a given grid cell g and uncertainty estimates u is given by Dig is the distance from feature i to the grid cell, Din is the distance from the feature to event location n, c is a constant, ÃŽÂ ¦E and ÃŽÂ ¦F are the position uncertainty for event and features respectively, I is the total number of features, and N is the total number of events. Figure 1(a) shows a sample forecast image based on this approach, denoting threat level with colors ranging from blue for lowest threat, through red for highest threat. For the same set of features and events, Figure 1(b) shows a more manageable forecast-in terms of allocating security resources-determined by aggregating feature layers prior to generating the likelihood values. Modeling Uncertainty One of the most important aspects of forecasting is having an estimate of the confidence in the supporting numerical values. In numerical weather prediction, there is always a value of confidence assigned with each forecast. For example, predicting an 80% chance of rain implies that numerical weather models given input parameter variations, predicted eight o

Analysis of Cancer - The Enemy Within Essay examples -- Exploratory Es

Cancer - The Enemy Within      Ã‚  Ã‚  Ã‚   Abstract: Cancer has been known and feared since antiquity, but its imperative danger could only be realized until fairly recently. Indeed as knowledge of the disease grew in the nineteenth and twentieth centuries, fear increased when people became more aware that most cancers had no available cure. Cancer is a disease in which abnormal cells reproduce without control, destroy healthy tissue, and eventually cause deterioration to the body. This paper is a discussion on how cancer develops and spreads, some of the various types of cancer, and the causes of the disease.    Cancer is a disease in which cells multiply without control, destroy healthy tissue, and endanger life. About 100 kinds of cancer attack human beings. This disease is a leading cause of death in many countries. In the United States and Canada, only diseases of the heart and the blood vessels kill more people. Cancer occurs in most species of animals and in many kinds of plants, as well as in human beings.    Cancer strikes people of all ages but especially middle-aged persons and the elderly. It occurs about equally among people of both sexes. The disease can attack any part of the body and may spread to virtually any other part. However the parts of the body which are most often affected are the skin, the female breasts, organs of the digestive, respiratory, reproductive, blood-forming, lymphatic, and urinary systems.    The various cancers are classified in two ways. The primary body site, as and by the type of body tissue in which the cancer originates. They can thus be divided further in to two main groups; carcinomas and sarcomas. Carcinomas are cancers that start in epitheli... ...r are fatal. In the past, the methods of treatment gave patients little hope for recovery, but the methods of diagnosing and treating the disease have improved greatly since the 1930's. Today, about half of all cancer patients survive at least five years after treatment. People who remain free of cancer that long after treatment have a good chance of remaining permanently free of the disease. But much research remains to be done to find methods of preventing and curing cancer.    Bibliography Allison, Trent. Background into Medicine. New York: Lincoln Press, 1982. Drummond, Phillip.

Consequences of a College Student Cheating Essay

Students are driven to cheat when there are too much emphasis to ace exams from both parents and school officials. It’s difficult to dismiss entirely of why students cheat, but taking the pressure away, students are less likely to engage in such conduct. Cheating implies breaking the rules. Academic dishonesty is using reference materials during a closed-book test or getting the answers ahead of time. Cheating is a significant concern in distance education programs. Students might find someone else to log in and take the exam for them or even have a teacher or more advanced student work with them while they take the exam. No matter how carefully a program is designed to prevent it, some students will always be able to circumvent the safeguards. This might seem like an easy way for a student to get a good grade and get ahead in his or her career. However, when students cheat on exams, everyone is affected. Consequences can vary considerably if a student is caught cheating. A grade of a zero is a standard consequence. Some professors may not report the cheating which only allows the student to continue the wrongful behavior. In most cases, the student will be put on academic probation for a first offense. This will affect the students’ career development because no one can succeed in their career if they have not learned what they were supposed to during the course of their college studies. The student may be able to get a job with more responsibilities and more pay, but they may not be able to keep it, or might even harm people. Whether the student’s career is medical assistant or lawyer, the exams are supposed to show the level of knowledge required for them to perform well. Another consequence of students cheating is that current and future students who do not cheat are penalized for being honest. When students cheat they change the rules of education in favor of themselves. If the course is graded on a curve, then the students who cheat will have their grades inflated and other students will do more poorly as a direct result. Even if the course is not supposed to be graded on a curve, grades are never absolute. Teachers might look at overall test scores and decide that a certain test was too hard, and that students should be allowed to drop a test score or retake it. However, if some students do extremely well because of cheating, then teachers will not know that the test was simply too difficult. They’ll have no motivation to change the test or the way the material is presented next time. With no feedback on their teaching style, teachers will continue to present the same material and the same kinds of tests. In fact, teachers may start to conclude that the tests are too easy because more students are getting very high grades. In other words, once a few students cheat the motivations for other students to do the same increase. When students successfully cheat they change the rules of education in favor of themselves. Cheating can create a culture of dishonesty. Once students find that one person is cheating it changes the entire ethics of the institution. It is harder for students to resist temptation if others are doing it. When it is recognized by the class that cheating is the only way to pass because majority of students are cheating, then the rest will begin to cheat. If students think that ‘everyone’ else is cheating, then it starts to seem right and normal. Because most young people do it, many young people don’t even see it as being wrong. Each person who participates in an anti-social behavior brings that behavior closer to the norm. Cheating can also devalue all students’ certificates and diplomas by casting a negative light on distance education. If society at large thinks that people in distance education programs tend to cheat, then they are less likely to want to hire people who have graduated from those programs. By maintaining academic honesty, students can make sure that their diplomas continue to have value and aren’t just seen as coming from a ‘diploma mill. ’ Finally, the consequences are severe if a student is caught. A student who is caught cheating will face at the very least failure of the assignment or exam. Harsher consequences include failing the course or possibly even expulsion from the institution. Cheating may seem like a rational decision, but the long-term consequences including the loss of money, time, and reputation that go with failing a class or being expelled can be devastating. Cheating has many consequences that shouldn’t be taken lightly. Even though the short-term effect might be positive, as the student collects some high grades, the long term consequences to fellow students, the institution, society, and the student he or she are not worth it.

Early Christianity in North Africa

Early Christianity in North Africa Given the slow progress of Romanization of North Africa, it is perhaps surprising how quickly Christianity spread across the top of the continent. From the fall of Carthage in 146 BCE to the rule of Emperor Augustus (from 27 BCE), Africa (or, more strictly speaking, Africa Vetus, Old Africa), as the Roman province was known, was under the command of a minor Roman official. But, like Egypt, Africa and its neighbors Numidia and Mauritania (which were under the rule of client kings), were recognized as potential bread baskets. The impetus for expansion and exploitation came with the transformation of the Roman Republic to a Roman Empire in 27 B.C.E. Romans were enticed by the availability of land for building estates and wealth, and during the first century C.E., north Africa was heavily colonized by Rome. Emperor Augustus (63B C.E.14 C.E.) remarked that he added Egypt (Aegyptus) to the empire. Octavian (as he was then known, had defeated Mark Anthony and deposed Queen Cleopatra VII in 30 B.C.E. to annex what had been the Ptolemaic Kingdom. By the time of Emperor Claudius (10 B.C.E.45 C.E.) canals had been refreshed and agriculture was booming from improved irrigation. The Nile Valley was feeding Rome. Under Augustus, the two provinces of Africa, Africa Vetus (Old Africa) and Africa Nova (New Africa), were merged to form Africa Proconsularis (named for it being governed by a Roman proconsul). Over the next three and a half centuries, Rome extended its control over the coastal regions of North Africa (including the coastal regions of modern day Egypt, Libya, Tunisia, Algeria, and Morocco) and imposed a rigid administrative structure on Roman colonists and indigenous peoples (the Berber, Numidians, Libyans, and Egyptians). By 212 C.E., the Edict of Caracalla (aka Constitutio Antoniniana, Constitution of Antoninus) issued, as one might expect, by the Emperor Caracalla, declared that all free men in the Roman Empire were to be acknowledged as Roman Citizens (up till then, provincials, as they were known, did not have citizenship rights). Factors Which Influenced the Spread Of Christianity Roman life in North Africa was heavily concentrated around urban centers- by the end of the second century, there was upwards of six million people living in Roman North African provinces, a third of those living in the 500 or so cities and towns which had developed. Cities like Carthage (now a suburb of Tunis, Tunisia), Utica, Hadrumetum (now Sousse, Tunisia), Hippo Regius (now Annaba, Algeria) had as many as 50,000 inhabitants. Alexandria considered the second city after Rome, had 150,000 inhabitants by the third century. Urbanization would prove to be a key factor in the development of North African Christianity. Outside of the cities, life was less influenced by Roman culture. Traditional Gods were still worshipped, such as the Phonecian Baal Hammon (equivalent to Saturn) and Baal Tanit (a goddess of fertility) in Africa Proconsuaris and Ancient Egyptian beliefs of Isis, Osiris, and Horus. There were echoes of traditional religions to be found in Christianity which also proved key in the spread of the new religion. The third key factor in the spread of Christianity through North Africa was the resentment of the population to Roman administration, particularly the imposition of taxes, and the demand that the Roman Emperor be worshiped akin to a God. Christianity Reaches North Africa After the crucifixion, the disciples spread out across the known world to take the word of God and the story of Jesus to the people. Mark arrived in Egypt around 42 C.E., Philip traveled all the way to Carthage before heading east into Asia Minor, Matthew visited Ethiopia (by way of Persia), as did Bartholomew. Christianity appealed to a disaffected Egyptian populous through its representations of resurrection, an afterlife, virgin birth, and the possibility that a god could be killed and brought back, all of which resonated with more ancient Egyptian religious practice. In Africa Proconsularis and its neighbors, there was a resonance to traditional Gods through the concept of a supreme being. Even the idea of holy trinity could be related to various godly triads which were taken to be three aspects of a single deity. North Africa would, over the first few centuries C.E., become a region for Christian innovation, looking at the nature of Christ, interpreting the gospels, and sneaking in elements from so-called pagan religions. Amongst people subdued by Roman authority in North Africa (Aegyptus, Cyrenaica, Africa, Numidia, and Mauritania) Christianity quickly became a religion of protest- it was a reason for them to ignore the requirement to honor the Roman Emperor through sacrificial ceremonies. It was a direct statement against Roman rule. This meant, of course, that the otherwise open-minded Roman Empire could no longer take a nonchalant attitude to Christianity- persecution, and repression of the religion soon followed, which in turn hardened the Christian converts to their cult. Christianity was well established in Alexandria by the end of the first century C.E. By the end of the second century, Carthage had produced a pope (Victor I). Alexandria as an Early Center of Christianity In the early years of the church, especially after the Siege of Jerusalem (70 C.E.), the  Egyptian  city of Alexandria became a significant (if not the most significant) center for the development of Christianity. A bishopric was established by the disciple and gospel writer Mark when he established the Church of Alexandria around 49 C.E., and Mark is honored today as the person who brought Christianity to Africa. Alexandria was also home to the  Septuagint, a Greek translation of the Old Testament which traditional has it was created on the orders of Ptolemy II for the use of the large population of Alexandrian Jews. Origen, head of the  School of Alexandria  in the early third century, is also noted for compiling a comparison of six translations of the old testament- the  Hexapla. The Catechetical School of Alexandria was founded in the late second century by Clement of Alexandria as a center for the study of the allegorical interpretation of the Bible. It had a mostly friendly rivalry with the School of Antioch which was based around a literal interpretation of the Bible. Early Martyrs It is recorded that in 180 C.E. Twelve Christians of African origin were martyred in Sicilli (Sicily) for refusing to perform a sacrifice to the Roman Emperor Commodus (aka Marcus Aurelius Commodus Antoninus Augustus). The most significant record of Christian martyrdom, however, is that of March 203, during the reign of the Roman Emperor Septimus Severus (145211 C.E., ruled 193211), when Perpetua, a 22 year old noble, and Felicity, her slave, were martyred in Carthage (now a suburb of Tunis, Tunisia). Historical records, which come partially from a narrative believed to have been written by Perpetua herself, describe in detail the ordeal leading up to their death in the arena- wounded by beasts and put to the sword. Saints Felicity and Perpetua are celebrated by a feast day on March 7th.   Latin as the Language of Western Christianity Because North Africa was heavily under Roman rule, Christianity was spread through the region by the use of Latin rather than Greek. It was partially due to this that the Roman Empire eventually split into two, east and west. (There was also the problem of increasing ethnic and social tensions which helped fractured the empire into what would become the Byzantium and Holy Roman Empire of medieval times.) It was during the reign of Emperor Commodus (161192 C.E., ruled from 180 to 192) that the first of three African Popes was invested.  Victor I, born in the Roman province of  Africa  (now  Tunisia), was pope from 189 to 198 C.E. Amongst the achievements of Victor I are his endorsement for the change of Easter to the Sunday following the 14th of Nisan (the first month of the Hebrew calendar) and the introduction of Latin as the official language of the Christian church (centered in Rome). Church Fathers Titus Flavius Clemens (150211/215 C.E.), aka  Clement of Alexandria, was a Hellenistic theologian and the first president of the Catechetical School of Alexandria. In his early years, he traveled extensively around the Mediterranean and studied the Greek philosophers. He was an intellectual Christian who debated with those suspicious of scholarship and taught several notable ecclesiastical and theological leaders (such as Origen, and Alexander the Bishop of Jerusalem). His most important surviving work is the trilogy  Protreptikos  (Exhortation),  Paidagogos  (The Instructor), and the  Stromateis  (Miscellanies) which considered and compared the role of myth and allegory in ancient Greece and contemporary Christianity. Clement attempted to mediate between the heretical Gnostics and the orthodox Christian church and set the stage for the development of monasticism in Egypt later in the third century. One of the most important Christian theologians and biblical scholars was Oregenes Adamantius, aka  Origen  (c.185254 C.E.). Born in Alexandria, Origen is most widely known for his synopsis of six different versions of the old testament, the  Hexapla. Some of his beliefs about the transmigration of souls and universal reconciliation (or  apokatastasis, a belief that all men and women, and even Lucifer, would ultimately be saved), were declared heretical in 553 C.E., and he was posthumously excommunicated by the Council of Constantinople in 453 C.E. Origen was a prolific writer, had the ear of Roman royalty, and succeeded Clement of Alexandria as head of the School of Alexandria. Tertullian (c.160c.220 C.E.) was another prolific Christian. Born in Carthage, a cultural center much influenced by Roman authority, Tertullian is the first Christian author to write extensively in Latin, for which he was known as the Father of Western Theology. He is said to have laid down the foundation on which Western Christian theology and expression is based. Curiously, Tertullian extolled martyrdom, but is recorded of dying naturally (often quoted as his three score and ten); espoused celibacy, but was married; and wrote copiously, but criticized classical scholarship. Tertullian converted to Christianity in Rome during his twenties, but it was not until his return to Carthage that his strengths as a teacher and defender of Christian beliefs were recognized. The Biblical Scholar Jerome (347420 C.E.) records that Tertullian was ordained as a priest, but this has been challenged by Catholic scholars. Tertullian became a member of the heretical and charismatic Montanistic order around 210 CE, given to fasting and the resultant experience of spiritual bliss and prophetic visitations. The Montanists were harsh moralists, but even they proved to lax for Tertullian in the end, and he founded his own sect a few years before 220 C.E. The date of his death is unknown, but his last writings date to 220 C.E. Sources The Christian period in Mediterranean Africa by WHC Frend, in Cambridge History of Africa, Ed.

Essay on Crime in America Part II

Essay on Crime in America Part II Essay on Crime in America Part II Crime in America: Part II Throughout my Crimes in America project, I chose to study and report crimes committed in and around Boston and the New England area. By doing this I was able to analyze which types of crime occur most often in the Boston area, as well as patterns and connections between these different crimes. During my research, I also found that while reporting these crimes, news outlets report from different stages in the steps in the Criminal Justice Process and add to their stories as time progresses. One pattern that was blatantly obvious throughout my research is that the most poplar crimes reported were violent crimes. For example, 13 of the 15 crimes I researched were of an outwardly violent and aggressive nature. These crimes ranged in everything from murder, attempted murder, bombings, and stabbings, to less serious violent crimes such as disorderly conduct and breaking and entering. One reason for this pattern may be that the Boston area is a dangerous, crime-ridden place, however I am not so sure that is the case. Crimes like these, although violent, occur everywhere, everyday around the country. I believe it is actually the press and todays media that give places like Boston a violent reputation. The media’s job is to report the news as it happens, however in today’s modern media, I believe they take some liberties with was they choose to report on. Crimes with a violent nature intrigue and scare people, which is exactly the emotions the media tries to expl oit in the public. Now, the media obviously doesn’t make up these crimes just to scare the public and sell newspapers, these events all did really happen to someone or something. However it is the way in which the media chooses to release the news that really shows their true motives behind their headlines. Crimes are also reported at different stages throughout the Criminal Justice Process, and each step gives a crime a different feel to the story. For example, If a story is just breaking and the police are just beginning to investigate a crime, the media doesn’t have a whole lot of

Apple iPad Mini Assignment Example | Topics and Well Written Essays - 750 words

Apple iPad Mini - Assignment Example Apple Inc. is one of the largest producers of electronics, computers, and software manufacturers. The company is among the top ten mobile phone production companies of 2012 (Gartner, 2012), and it was recognized as the most powerful brand in 2012 (Badenhausen, 2012). To determine the quality level, iPad Mini must be reviewed from three different aspects. The first is its build quality. iPad Mini has a tough body made from aluminum making it lighter than its predecessors. The second aspect is its screen resolution. The screen resolution of iPad Mini is 163 pixels per inch; whereas the resolution of the tablets provided by Apple’s competitors is 216 pixels per inch. The 163 ppi resolution fails to deliver the display quality standards that have been set by iPad third generation. The third feature is the battery time of iPad Mini. The iPad Mini does a fair job when it comes to the battery life. Compared to the size and resolution of the device, iPad Mini does quite a decent job. However, when the battery life is compared with other products in the market the battery life of iPad Mini is quite disappointing. As with every Apple product the packaging of iPad Mini is always attractive. The box measures 5.75x8.25x1.5 inches. The iPad Mini’s box comprises of a USB cable, wall socket adaptor, and iPad quick start sheet. Apple Inc. is known for the beauty of its products and like all other Apple products iPad Mini has high visual appeal, which makes it highly trendy. The dimensions of basic iPad Mini are 200Ãâ€"134.7Ãâ€"7.2 mm. The sleek design of iPad Mini makes it comfortable for the user to hold in his hand and operate it. The difference between iPad and iPad Mini is the size of the screen. The size of the iPad Mini has been significantly reduced from 9.7 inches to 7.9 inches. Smaller size of iPad Mini allows users to carry it around with ease, using their favorite applications from anywhere they like. The

A accounting calculations Essay Example | Topics and Well Written Essays - 500 words

A accounting calculations - Essay Example According to Caplan (2006) suitable methods like value engineering and value analysis could contribute to reducing the cost of the three products. It helps in sorting additional overhead components like cooperative marketing, high levels of customer service, and product return handling to identify profitable customers. The approach enables the organization to put more emphasis on clients who earn large profits for the company while turning away unprofitable customers (Caplan, 2006). Distribution of product is a major undertaking for all enterprises. Most companies employ different channels of product distribution like email, distributors, the Internet, retails shops, and order catalogue. Reducing distribution cost is the primary function of ABC. Structural components that maintain the distribution falls under overhead. Therefore, ABC helps in deciding efficient delivery systems with lower costs or dropping unprofitable channels (Caplan, 2006). ABC helps the management decide on whether to buy or make a product. It does this by highlighting costs associated with product manufacturing. Such is the basis that guides one to either outsource or carry out in-house manufacture. Using ABC makes it easier to allocate overhead costs appropriately. Such allocation assists in determining margins of product lines, products, and their subsidiaries. The information guides the personnel to identify areas that would give maximum return margins (Caplan, 2006). The model assists marketing managers decide on the minimum price for the product. ABC model guides the marketing personnel to select particular overhead costs for inclusion in the minimum cost. The approach eradicates the possibility of selling a product at a loss or overpricing (Caplan, 2006). Using ABC model increases the cost pool volume, which increases the cost incurred to manage the system. A reduction in cost pool involves running a system that analyses and maintains the cost
