The History And Background Of Yahoo Marketing Essay

The History And Background Of Yahoo Marketing Essay A company symbol is regarded as a unique mark or design that identifies a certain firm. In most cases, a company symbol tends to be more important than the assets of a company when it comes to the companys identification by the public. All of the international as well as regional business firms, including Yahoo, tend to have their specific company symbols, which helps them for public identification. For instance, the company symbol for Yahoo is Yahoo! (Mortensen p25). The key executives of Yahoo are committed business individuals who ensure that the firm runs smoothly in the business fraternity. Yahoos key executives include Marissa Mayer who is the Chief Executive Officer, the President, as well as the Director of the company. David Filo is the Co-Founder and Chief of Yahoo!. Kenneth Goldman holds the key position of the Chief Financial Officer. Ron Brachman is the Chief Scientist and Head of Yahoo! Labs. Finally, there is Henrique De Castro who holds the position of Chief Operating Officer at Yahoo! (Snell p31). Yahoo is an American internet corporation, which has its headquarters in Sunnyvale California. The firm was found by two individuals, David Filo and Jerry Yang, in 1994, and was incorporated in the business world in March the year 1995. Yahoo tends to generate its revenue from the display of text-based links to advertisers Websites, which is regarded as search advertising, from the display of graphical advertisements, which is regarded as display advertising, as well as from other relevant sources (Snell p33). As an internet corporation, Yahoo offers a number of products and services to its esteemed customers. The company has a strong technology and insights that helps it in the delivery of digital content and experiences across the globe and communication devices. The firm tends to provide online services and properties to its users, as well as marketing services aimed to connect with Yahoo! users. This is done through a distribution of network of third party entities. Through its search engine, Yahoo! Search, and its web portal, the firm provides services such as advertising, Yahoo! Mail, Yahoo! Finance, Yahoo! Directory, fantasy sports, online mapping, social media website, Yahoo! News, as well as Yahoo! Groups. The firm has properties, which are tailored to users in certain international markets. The properties include social networking websites (Meme and Wretch), and Yahoo! Homepage (Mortensen p69). The services offered to users of Yahoo are divided under three categories. The categories include Media, Communications and Communities as well as Search and Marketplaces. Under the Communications and Communities category, the firm offers Yahoo! Messenger, Flickr, Yahoo! Answers, Yahoo! Mail, Connected TV, and Yahoo! Groups. Services offered under this particular category enable the users to organize themselves in groups and share photos, common interests, as well as knowledge (Snell p47). The Search and Marketplaces category tends to answer the information needs of the users through the search results pages and across Yahoo!. The search offerings of the company include Yahoo! Local, and Yahoo! Search. These offerings are free of charge for the users and help them discover new content on the internet. On the other hand, the Marketplaces offerings include Yahoo! Small Business, Yahoo! Real Estate, Yahoo! Travel, Yahoo! Shopping, and Yahoo! Autos. With these properties, the company enables users to research and review specific topics or fields of interest and exchange information with parties of similar interest (Snell p49). The final category is the Media whose services are tend to engage the Yahoo users with online services and content especially on the web. The services provided under this category are free of charge to the users. Services provided include My Yahoo!, Yahoo! Finance, Yahoo! Homepage, Yahoo! Toolbar, Yahoo! News, Yahoo! Entertainment, Yahoo! Sports, and Yahoo! Contributor Network (Snell p48). In the internet business, Yahoo tends to have a number of competitors who keep the company on toes in terms of performance and service provision to the customers. The main competitors for Yahoo! include Google Inc., Acxiom Corporation, Agilysys, Inc., AOL Inc., Adobe Systems Inc, Facebook Inc, and Callidus Software, Inc. among others. These competitors tend to compete in terms of service provision to the internet users. The top competitors of the named ones for Yahoo are Google Inc., and AOL Inc (Mortensen p72). The key executives in the firm head the structure of the organization. The head of the structure is the Chief Executive Officer who is also the president of the firm. The Chief Executive Officer usually does most of the managerial activities and decisions in the firm. Other key executives who makes the top of the organization structure includes the Chief Operating Officer, Chief Financial Officer, Chief of Yahoo, and Chief Scientist and Head of Yahoo Labs. The growth and development of the firm majorly depends on these individuals (Associated Press). The management of the company mainly lies in the hands of the Board of Directors and the Key Executive members of Yahoo. The management team of the company tends to manage business at the company by ensuring that employees perform their duties as scheduled, and that the users of Yahoo receive the best products and services in the market (IFM). In 2011 September, the management team headed by the chair of the firm decided to fire the then Chief Executive Officer, Bartz. This decision was consequential in terms of business for Yahoo when a number of potential buyers came in with the idea of buying parts or rather the whole firm. In September 2012, the current Chief Executive Officer of Yahoo made a decision of closing the deal the company had with Alibaba in her managerial post. This particular deal; was controversial and it earned the company a negative image in the business fraternity. The closure of the deal affected the companys financial function in a positive way by giving the company 625 million US Dollars (IFM). In relation to sales and earnings of the key financial finding for Yahoo is that the company has been able to grow its bottom line. In the 2012, despite the stagnant revenue growth, the companys bottom line was able to grow from 1.0 billion US Dollars to 3.9 US Dollars. In the earning statement of 2012 delivered by the companys Chief Executive Officer, she stated that the firm was able to show a revenue growth in 2012 for the first time in a period of four years. The variables that tend to affect the earnings of the company include revenue, earnings per share, price to earnings ratio, and return on equity. The variables tend to change from time to time and this affects the earnings of the company (Mortensen p56). There are a number of activities and decisions that the company did to affect its financials. For instance, in 2012 during the quarter that the company made progress in its financials, it is indicated that various activities took place. The CEO stated that the executive team was reshuffled leading to its growth, there was the launching of unbelievable Yahoo! mail and Flickr mobile experiences, as well as signing of major business partnerships with the CBS Television, and NBC Sport (Snell p38). There are also a number of decisions that the company made which led to negative impact of its financials. They include signing a business deal with the Alibaba group, creation of the Yahoo! search image in 2006 that brought up sexually explicit images, and rejection of Microsoft Corporations bid of acquiring the firm in 2008 on the basis that Microsoft had undervalued it. These decisions led to the fall of the companys financials (Mortensen p81). It is with no doubt that global issues are affecting business at Yahoo. For instance, there are various global issues that can be discussed. Advancements in technology is one of the global issues that affect business at the company since it is an internet company. Many technologically advanced companies around the globe are coming up with advanced internet service provision, and this tends to keep Yahoo on toes (Belew and Joel p35). Another global issue of concern is the fact that majority of people around the globe communicate through the social medias in the internet. Since the company offers such services, increased numbers of subscribers on social networks around the globe affect business operations at the company. The company has to provide the best services to its customers (Belew and Joel p33). Challenges that Yahoo! has been facing over the years in business operation is a relevant topic that was left out. One of the main challenges that the company has been facing in the past years is poor management. For instance, until the appointment of Mayer as the Chief Executive Officer of the firm, the company had plunged into poor leadership. This is clearly indicated by the poor financial reports the company used to report in the past years (Belew and Joel p56). Another challenge that the company faced in the past, and was a great loss is the fact that the company had signed a business deal with Alibaba Group and that it had created a Yahoo! Search image that showed sexually explicit images. The company received a lot of criticism from the public, whereby it lost some of its customers (Mortensen p43).

Root Surface Caries Essay -- essays research papers

Root Surface Caries Caries can affect any surface of the teeth. The most commonly seen caries are found on the crown of a tooth, above the cemento-enamel junction, it is also possible for caries to form on the root surface, below the cemento-enamel junction. Dental root caries has received a great deal of attention in the past few decades. A variety of different patients are at risk for root surface caries. Dentists use several methods of treatment. Root surface caries are also called cemental caries, cervical caries, or radicular caries. (Wilkins) Root surface caries only involves the roots of teeth. The cementum and dentin located just below the crown of the tooth is involved. No involvement of enamel is seen with root surface caries. Bone loss and corresponding gingival recession are the first symptoms to be seen in the caries process. These result in exposed root surfaces, which are more prone to forming caries because caries does not form in the root surface while periodontal fibers are still attached. Clinically, the lesion starts on the root surface. It has been found that root caries spreads in a lateral or circumferential manner, and over time can extend completely around the tooth, undermining the enamel. (Wilkins) In general, root caries have the same etiology as coronal cavities. S. mutans, Lactobacilli, and sometimes, Actinomyces are involved and are found in high numbers in root caries, but there are two main differences between enamel and root surface caries. (Flaitz) These differences cause the lesion on a root surface to be more destructive than that in enamel. First, because the pH at which demineralization will occur is higher for root cementum (approx. pH 6.0) than for enamel (approx. pH 5.0).(Wilkins) Therefore, root cementum has potential for demineralization at an earlier point in time than enamel does. Secondly, once the cementum is demineralized, the dentin contains dentinal tubules which, if present, are potential methods of entry for the pathogenic microbes as mentioned previously, such as S. mutans, Lactobacilli, and sometimes Actinomyces; whereas, enamel consists of tightly-arranged crystal prisms, which have a much lower chance for bacterial entry. The process of caries form ation begins with colonization by acid-producing bacteria plaque. In the next step, Gram-positive bacteria invade the dentinal tubules, which leads to the ... ...at more tentatively, with fluoride gels and varnishes or a chlorhexidine varnish. Some dentists may restore root caries with amalgam restorations. Another treatment option used by some dentists to restore root caries is Glass Ionomer Cements. Glass ionomer cements were first introduced in the early 1970s. They have good adherence to mineralized tooth tissue, which keeps the removal of tooth structure to a minimum. Glass ionomer cements also have the ability to leak and absorb fluoride into the tooth, which decreases the rate of secondary caries. These factors have increased the potential for glass ionomer cements to replace amalgam as a restorative material. (Hammel) Although the most common caries seen are coronal, root surface caries present just as much of a problem. Once root caries are detected, the bacteria have already begun to demineralize the cementum or dentin and create a great deal of damage. There are several different ways that root caries may appear clinically. A variety of different patients are at risk for root surface caries. Different measures can be taken to prevent root surface caries. Methods of treatment differ among dentists, but there are several choices.

Exploring Dyslexia and its Implications Introduction Imagine yourself in a crowded room. You are sitting at a table with other people your age, reading a book out loud, and it is your turn. You look up at the other people, terrified because nothing is coming out of your mouth. You can't manage to force even one word out because you don't know how to read. Now, imagine yourself as a teenager. This is what it was like for fourteen-year-old Anita, a dyslexic. Life was horrible for her. She said that "Dyslexia makes you an outcast, and people think you are dumb...It's like racism; people are just prejudiced" (McConville, 2000). Feeling useless, she got herself into a lot of trouble: drinking, smoking and two attempts of suicide. Dyslexia seems like such a minimal disorder, but what is it really, what causes it, and how can it be treated? What is dyslexia? Dyslexia is a reading disorder. It is something that affects not only the reader's life, but also the lives of everyone around him or her. It is a very random condition, but it is four times more common in males than in females. The race, culture, and society are not considered when dyslexia decides who it will attack, but when it does, it causes symptoms that differ from difficulty in spelling to lack of self confidence and difficulty in pronunciation to a bad short-term memory (Bee, 2000). There are many theories of how dyslexia is caused. One is that it is inherited. Another is the lack of certain nutrients obtained by eating some foods.

Human Resources function Essay

In this assignment we were instructed to select a business in which to analyze its Human Resources function. After a long deliberation I chose to discuss Tesco. There are several factors that influenced my choice one of these factors was accessibility of information on Tesco. I feel that in order to produce a vivid and constructive assignment, accessibility of background information is essential. Another factor that influenced my choice of business was familiarity, and the fact that I am a regular customer of Tesco’s and have friends and relatives that work for the company presently or have done in the past makes producing an in depth assignment on Tesco’s Human Resource function, much more straight forward than if I had no awareness of the company at all. Tesco is a nationwide food retailer and has stores all across England as well as some parts of Europe it specializes in the sale of food and other household goods and necessities. Tesco is today’s leading food retailer in the country, however without good employees the company would have never reached its current status and this is the case of most of the nations leading stores and companies. It is a well known fact that human resources is the most significant resource to any large scale business or company overweighing capital, buildings, land, equipment and materials or any other resource. The purposes of human resources are to attract and keep good, hard working, high quality staff. And the other purpose of the human resource sector is to dismiss low quality, lazy unhelpful workers who are known as liabilities to the company. This is important to a company like Tesco for high quality staff is hard to come by so it is important that the functional area under which the human resources is in does its best to retain good, hard working internal customers for as I previously mentioned the staff is considered to be the company’s most significant resource. Another purpose of the human resources section in Tesco is to train and develop all their employees to enable them to reach their full potential and do the work in which they have been employed to do to the best of their ability. By Tesco training and developing their staff even the members of staff who are not the best at their jobs develop into sufficient high – quality workers and this benefits Tesco for they could possibly save money, for instead of employing 10 workers to do one particular job for instance they can use 4/5 of the employees that they have been trained for the employees would be highly sufficient and would probably do the work quicker and of a higher quality than 10 new employees and in addition save Tesco money. Another purpose of the human resources sector is to ensure that Tesco’s avoids unlawful or unfair discrimination. This purpose is important for the company for if discrimination was not unavoidable by the human resource sector many workers would find Tesco an unpleasant working environment and when they come to work would put limited effort into their job hence developing a bad name for the organization. The last purpose of the human resource sector, which I am going to put into perspective, is to ensure that Tesco operates within the law in relation to employment and health and safety. This purpose is very significant for it provides employees with information about laws which apply to health and safety and employment therefore they wont violate these laws unknowledgeable. Like most functional areas in Tesco the human resources sector also have activities that staff within the human resource sector have to undergo. One of the human resources activities in Tesco is to recruit, retain and dismiss staff this is an important activity and requires a lot of attention. The human resources center has to deal with the recruitment of staff, they have to hold interviews and undergo research for applicants who want to work for Tesco. This activity requires not only interviews and research but it also requires the human resources sector to advertise placements. Another thing this activity requires is to retain good high quality staff; the human resources can manage this by acting as consultants and helping members of staff in everyway possible. In addition the human resources have a duty to ensure that Tesco maintains a good working environment and therefore form good working relationships between staff so there is an endless pleasant felling in Tesco and it would prevent good workers from leaving Tesco as a result of hostility within the organization. It is also very important that Tesco allows its internal customers to have sick leaves lunch brakes etc. to relieve any pressures of work which the employees could fell they would need to resign. One more activity, which I am going to put in to perspective, is the dismissal of staff. The company has to deal with many incidents of staff dismissal every year but it is the human resources sector that deals with them directly. It is the human resources job to give warnings to employees i.e. verbal warnings for lateness and then written warning etc. so when a employee violates Tesco’s company policy whatever it may be, it is then the human resources responsibility to provide a notice to the member of staff who has violated company policy that they have been dismissed from the company in other words â€Å"sacked†. Another set of activities, which the human resources sector has to deal with, is the training, development and promotion of employees. The training of employees in Tesco is done solely by the human resource sector. It is human resource that decides what kind of training a particular employee needs, when the particular employee needs training and how long will the employee need to be trained for. For instance if a member of staff was appointed trainee manager of Tesco it would then be the responsibility of the human resource sector to decide how long the employee should train for depending on the particular employees personal ability. The training of Tosco’s internal customers is part of its employees development, the reason for this is because the training of employees is to do with the development of skills i.e. communication with customers. The provided training at Tesco’s helps develop skills for many employees every year for Tesco’s nurtures all its employees and gives them skills to carry along with them to future employment when they leave Tesco if they should leave. Another aspect, which the human resources sector in Tesco has to deal with, is the promotion of its staff. I feel every member of staff regardless of their role whether they are toilet cleaners or till assistants are entitled to promotion after being part of a company such as Tesco for a certain amount of time. However, the statement I have just made is not how Tesco runs its promotion opportunities there are other factors that Tesco’s human resources look into when considering an employees promotion. One factor that the human resources look at is how interested you are with your work and how interested you are with Tesco itself, the human resources look for employees who have actually gained an interest with their work and the organization when selecting an employee to be promoted, this is important for Tesco for an employee who has an interest with the company and their job is likely to put more effort and sufficiency in their work than somebody who has a low amount of interest for the company and their job. Tesco’s human resources sector also looks at a promotion candidate’s ability to get along with their fellow employees. This is also an important factor for Tesco when deciding to promote a member of staff to a higher role for they want to promote friendly/pleasant characters as opposed to hostile/rude employees who don’t get along with anybody in their current role let a lone a higher role where they will be in contact with more employees. Another factor that the human resources look at is the employee’s ability to manage their current job exceedingly well. In my own personal opinion this is the most significant factor apart from † how long the employee has been working with the company for† when deciding to promote a member of staff into a higher position. I feel this is the most important factor the reason being is that you cannot possibly promote a member of staff onto a higher position with higher pay cheque and higher responsibility when they are struggling or just about managing with their current job. The next set of activities that the human resources sector have to undergo in Tesco that I am going to put into perspective in this assignment is the monitoring and maintenance of good working conditions. Good working conditions are enforced by Tesco’s human resource sector and list of the conditions are presented to all new employees when they start at Tesco. Some of the information presented to the new employees on the list of terms and conditions include, the address of their work placements, the employees hours of work, the employees wage and also additional payments such as commission, bonuses and overtime. Also in them list of terms and conditions are employees holiday entitlements per year both personal and statutory days e.g. Christmas, whether the employee will receive sick pay and if so on what basis i.e. only with a Doctors note. In addition the list of terms and conditions, which are presented to all new employees at Tesco’s, include pension rights and any f ringe benefits, for example share rewards staff vouchers etc. The working conditions are regularly inspected by staff from the Human resource sector to ensure that the working conditions in Tesco is kept at a superior standard to ensure that employees can do there work well without worrying about any obstacles distracting them from their work. The physical environment such as good lighting and ventilation, modern furnishings and equipment, adjustable heating, low noise pollution and a restful color scheme. In Tesco, in their attempt to make sure there is an endless pleasant environment and good working conditions in the store the human resources offer employees personal services such as free medical screening and the availability to talk to counselors whenever they are experiencing any personal problems. By Tesco helping their internal customers in this way it can help to relieve a lot of tension and maintain a good working environment for Tesco’s employees. The last activity I am going to put into perspective that Tesco’s human resource sector undergoes is health and safety. The UK law requires internal customers as well as employers to conform to the health and safety legislation. Like most organizations Tesco have a health and safety officers who advises the managers at Tesco about their responsibilities in regards to the health and safety law it is, also it is the role of the health and safety officer to ensure all employees are kept informed about the health and safety law via the manager. In addition it is the human resources sector that makes sure that there is a display of the details of the health and safety law that is displayed where everyone working in the store can in the store can see it.

Greener Forms of Generating Electricity

A power station is a facility which is used to generate electric power. iAt the center of nearly all power stations is a generator, a rotating machine that converts mechanical energy into electrical energy by creating relative motion between a magnetic field and a conductor. In Bosnia there is a lot of hydro power plants, the biggest ones are: Grabovica, Jablanica, Salkovac, Visegrad etc. There are three different types of power plants, thermal power plants, hydro power plants and solar power plants. In order to make our lives and the lives of our offspring better, we need to investigate and design new greener ways of converting mass amounts of energy into electricity. Solar power plants use an endless power, which is the sun. Beams from the sun hit mirrors which convert the suns energy into electricity. Approximately, every 7. 2 hours, 3. 6kWh electricity is produced. Solar power is clean and green and it can provide enough energy. However, the downside to this type of power is that it isn't cheap. Building a single mirror of 3. 8 meters by 1. 6 can cost up to $60. 00. These mirrors are state of the art which capture the suns light, and turn it into energy. Thermal power plants are bad for the environment because they contribute to global warming by burning fossil fuels. These power plants are still in use today, because they provide a lot of energy and coal is cheap, so it can be burned in large quantities. Most houses today are supplied either by thermal or hydro. Thermal is very bad for the environment and since the industrial revolution kicked in global temperatures have been rising. Another type of power is wind power. Wind turbines are rotary devices that get provide energy using the air. This type of technology is not to be sniffed at as wind power can sometimes provide more energy than burning coal. There is a downside to this as well. Staying green and using wind powered turbines can cost a lot of money. Staying green and investing in these ideas will matter in the future. By burning excess fossil fuels we are creating green house gasses which are heating up the planet, thus destroying a lot of environments. (2) In Bosnia, the biggest hydro power plant produces around 170. 00 cubic meters of water that reach speeds of 60 km per hour. This is enough water to fill up around 100. 000 Olympic swimming pools every day. Hydroelectric stations have been up and running for about 100 years, and since been scientists have been searching for a way to harvest the energy better. The main idea behind these power stations is to convert the energy of flowing water into the flow of electrons or electricity. Most hydroelectric stations use either water diverted around the natural drop of the river such as a waterfall or rapids. In addition to this a damn is also built across the river to raise the river to create the drop needed to provide a force. Water in the higher level is collected in the reservoir, which flows into the pipe called the pen star which carries it down to a turbine water wheel at the lower water level. The water pressure increases as it flows down the pen star, it is this pressure and flow that drives the turbine which is connected to the generator. Inside the generator is the rotor which is spun by the turbine. Electro magnets are attached to the rotor located within coils of copper wires called a starter. AS the generator rotors spin the magnets, a flow of electrons is created in the coils of the starter. This produces electricity that can be stepped up in voltage through the stations transformers and sent to this transmission lines. The following water the proceeds down the river. Most of our energy comes from the spinning of the rotor of the AC generator in power stations like Nuclear power stations, thermal and hydro power stations. An AC generator is a device which converts mechanical energy into electricity. The working of an AC generator is based on electromagnetic induction which states that whenever the flux passing through a circuit changes, an EMF is induced in it and a current begins to flow. The direction of this is given by Lenz`s law or Flemings right hand rule. Lenz`s law which is more commonly used states that the direction of the induced current is such as to oppose the very cause producing it. (1) In our homes we use open electrical circuits which is very important as with them we do not use direct current. If we were to use direct current many more fires caused by electricity would happen and appliances would not function well and they would simple burn out. We need electric circuits for everything, they are what keeps our appliances running safely. Today using thermal power plants is a big problem as it affects many factors. Countries in the EU have to follow certain conduct when it comes to power plants. For instance Nuclear power plants have to have the right materials, funding etc, thermal power plants have to have filters, can`t produced to many greenhouse gasses etc. the waste that comes out of these plants are often dumped into the rivers or oceans, this kills a lot of marine wildlife which local farmers depend on. These power plants also affect our environment; they can both help and destroy our environment. The waste produced in power plants is often thrown out in the forest, or lakes and seas. On the other hand solar and wind power can help with the environment by providing a clean way to get energy.

Mother Tongue Language And Mathematics Essay

In what ways does your mother tongue language and mathematics resemble and differ from each other? Mathematics and language both act as a source of communication, thus both mathematics and language play an important role in life. According to the dictionary, language is defined as a â€Å"communication of thoughts and feelings through a system of arbitrary signals, such as voice sounds, gestures, or written symbols.† In comparison, the dictionary defines mathematics as a â€Å"the study of the measurement, properties, and relationships of quantities and sets, using numbers and symbols.† Both language and mathematics use symbols, thus both concept are seen as a form of communication. The symbols represent values, which can be understood by the human mind. Language is defined as a code, and both the mother tongue and mathematics are made up of unique symbols that are consistent in their rules in order to be understood properly. Mathematics is a very complex, straightforward concept that has fixed meanings. If x = y = z, then x = y, x = z and y = z. This is a universal phenomenon accepted world wide. Mathematics has been used in the study of science. An example would be the physician Albert Einstein and the discovery of his equation e = mc2. Mathematics is composed of a combination of factors, which can be simplified and broken down. Factorisation of equations is an example. However, if an equation can be factored, then there is only possibility in which it can be broken down. Each equations has its universal values that cannot be altered. Even though mathematics exemplifies logic, it is not as simple to understand. In order to understand the concept of mathematics, a person has to learn a language first. Whether the language is English, French, Spanish or German does not matter. Mathematics is a fundamental base of our daily life and society, but it is not as essential as the communication between humans through the usage of language. Language is a much simpler concept than mathematics. Language does not have a fixed meaning or value, whereas this is the case in mathematics. 5 + 3 = 8. This is always true, it cannot be denied due to the mathematical code and its rule. In language this is not the case. Statements can be understood of accepted differently according to the individual. For example, Anna says to Tom, â€Å"I really like you.† This has no fixed meaning, because according to what tone this statement is said, it can either be true or false. Anna could emphasise through language that she in reality does like Tom. On the other hand, she has the ability to state it as a sarcastic phrase. This would mean, that in reality she doe not like Tom. Language also plays an important role in culture. Through language, the origin of individuals can be assumed. If somebody is mainly speaking German, then one can assume that the person is German. Even within the German language, different dialects are spoken. This makes language less specific than mathematics. There is the â€Å"Hoch-Deutsch† spoken in Germany, the Austrian German spoken in Austria and finally the Swiss German heard in Switzerland. Language is expressed in different forms, either written by the usage of symbols, orally through the usage of sounds and finally through the form of body language. Again, language illustrates a less specific concept than mathematics. All three forms can express certain values and one statement, such as â€Å"I like you† can be expressed in all three different forms. Even though both mathematics and language have codes, these can be misunderstood. In mathematics your result is an error, while in language misunderstandings can result in several problematic situations. The fundamental difference between mathematics and language is that one is universal in its concept, while the other is altered around the globe. Mathematics is universal, it has the same code throughout the world where 2 + 2 = 4 in every country. Language however, can be altered. If a Chinese speaks in Chinese to a Portuguese, it is unlikely that they will understand it each other. In conclusion, mathematics and language share both common concepts but also differ from each other. They are both essential for life, while language is the base to understand mathematics. The concept of mathematics has always been relevant in nature, such as 360à ¯Ã‚ ¿Ã‚ ½ circles. Language is the invention of the human race in order to establish and maintain the communication between each other.

Complimentary and Alternative Therapies - Essay Example This hospital network was expanded, reworked and merged with the intention of providing a single District Hospital supporting local GP's and in turn being supported by teaching and specialist hospitals. These District Hospitals have 500 to 800 beds and operate at 90% capacity. (nhshistory.com). The availability of CAM in the organised NHS is very little. In fact CAM is hardly reimbursed under the NHS network. Most CAM services were provided by private practitioners - the majority were in the home counties and the Midlands; Northern Ireland, Wales, Scotland and East Anglia had the least. (Dixon et al 2003) Several studies and enquiries show that the use of CAM in the UK has been on the increase. But comparisons should be made with caution, because of the differences in the definition of the term. (House of Lords Report ch1) A telephonic random survey of 1204 persons conducted by the BBC in 1999, revealed that 20% of the respondents had used CAM in the preceding 12 months. Of these the favoured therapies in their order of importance were herbal remedies (34%), Aromatherapy (21%), Homeopathy (17%) and Acupressure/ Acupuncture (14%) (House of Lords Report ch1) A Report prepared by the Royal Pharmaceutical Society in 1999 found that retail sales of complementary medicine preparations came to 93m in 1998. (House of Lords Report ch 1) In Europe, both UK and Germany are countries, ... her European countries (Guillod, 1999)."(Dixon et al 2003) This is in contrast with France, Spain and Belgium, "where the medical profession has maintained its monopoly over medical practice and where the activities of non-medically qualified CAM practitioners are illegal." (Dixon et al 2003) In the US too, a telephonic survey indicated that from 1900 to 1997, there was a noticeable increase in the already existing use of CAM. Out-of-pocket expenditure (paid for by patients, and not reimbursed) on this was estimated at $27.0 billion in 1997. (House of Lords Report ch1) What are the reasons for people shifting to CAM The possible reasons for using CAM is the need for people to have control over their own health, a philosophical and spiritual orientation, and a belief in the mind-body connection. It was found (in the US) that people of higher educational status tended to CAM. (House of Lords Report ch 1) This could probably be that those who had access to literature on the subject, and had an enquiring mind would use this to a greater extent. Another reason could be that conventional medicine is reimbursed, and not CAM. Presuming that better educated people had higher incomes, this would explain why CAM was (is) favoured by higher income groups as opposed to the lower. Apart from this, sufferers from chronic health problems such as anxiety, back problems, urinary tract problems and chronic pain used CAM. From this it may be deduced that conventional medicine had not provided a complete 'cure' for these problems. Another reason cited for the increase d use of CAM is that it had become fashionable, and also due to the increasing interest in the paranormal (astrology and the like). More social mixing (immigrants from Asian and African countries) resulting in interest
