Company Analysis for Yahoo - Research Paper Example Basically, Yahoo was only accessible by the two engineering students but because they had created a web interface that had allowed other people to access to their guide and because of apparent knowledge of Yahoo and its existence in lieu of the word of mouth and electronic mail, more people began using their web site and because of Yahoo's strong as well as positive impact to the people and the society amicably, Yahoo has a complex environment. Due to this complexity, the department is considering all the factors that affect its task environments. Some factors such as political-legal and economic climates are encouraging to the growth of the department. However, the sociocultural climate is posing a challenge. Nevertheless, Yahoo is generally having a stable environment. The political-legal climate of corporations globally has been generally encouraging. This is especially for yahoo in which it reciprocates the government's trust on the company by sharing 30 percent of its shares to the government. Likewise, the economic climate globally has seen the growth of systems of wealth production, distribution and consumption. However, inflations and recessions affect the operation of Yahoo. These are the factors over which we have little control. The sociocultural climate represents the attitudes, values, norms, beliefs, behaviours and associated demographic characteristics of the population within which an organisation operates (Daft 1997, p. 78). In operating and managing Yahoo applications that support users, we have to consider our customers' values and beliefs. To do this we conduct studies to identify the concerns of our customers. The technological climate includes scientific and technological advancements in the production of goods and services (Dahlgren and Whitehead, 1991). Technology for Yahoo is of particular importance because it has been and continues to be the main source of increases in productivity, which means it can either provide a competitive advantage to organisations that can use it effectively, or pose a threat to those that lack it. To remain competitive therefore, it is important that we need to understand current technology developments affecting their ability to offer desirable products and services. The pace of change in that industry, of course, is accelerating, and its scope and impact are widening. Spectators of the technology can trace that change from the earliest antecedents of Yahoo, to the most recent developments. Spectators can also scan the entire Yahoo continuum from the 19th century to the 21st or pinpoint, year by year or decade by decade, but the focus of this paper will only be from 1998 to 2003. These are the years and key events that have led to the Yahoo of today and it has shown through the use of the company's corporate strategy. It is said that people are living through an era in which organizations

Reflection - Essay Example 2). These points are the ones that appeal to me most from Sirico’s publication. I think the new concept highlighted in the publication is the fact that entrepreneurship is similar to other professions; therefore, it is prudent to afford entrepreneurs with the same level of respect. Judging them based on stereotypes originating from biased, archaic religious perceptions does little to encourage those in the vocation to engage in ethical business practice. Positive consequences result from applauding the innovative, intuition-filled actions of entrepreneurs, as it affirms their ability to create something in spite of dire circumstances. In my opinion, if the world regarded entrepreneurship as a vocation, there would be a limited need to use regulatory policies to coerce entrepreneurs to conform to business ethics principles. Ensuring ethical practices would become second nature, as entrepreneurs would regard these practices as their inherent duty to the public. They would endeavor to ensure their practices result in positive outcomes rather than harmful

Topic and proposal - Dissertation Example The highly accepted classification of SMEs in UK and EU attributes to â€Å"the number of employees or annual turnover, with small enterprises constituting of less than 50 employees and medium size enterprise at more than 50 and less than 249 employees† (BIS Department for Business and Innovation Skills, pp. 1-7, 2010). The nature of ownership in SMEs is either the individual entrepreneur or the family investments, which later on is inducted by directors on behalf of the majority shareholders. The SMEs sector in UK has jumped to an enormous boom in the last couple of years by increasing the net to 400,000 firms every year and even the micro businesses or self-employment has contributed a significant turnover for over ? 200 billion to the economy even in the severe economic turmoil of recession on inflation (Amble, pp. 20-29, 2004). The small and medium sized business has emerged as a powerful source in contributing to net revenue of the economy by intervening for almost 13 % i n financial and business intermediation, such as real estate and business operations. In addition, by contribution in 12% to agricultural and fishing business, wholesales and retails at 21% indicating to largest contribution to the private sector turnover (BIS Department for Business and Innovation Skills, pp. 1-6, 2010). The role of SMEs enterprises has played a significant part in the economic and social growth followed by the industrialization, income, and employment generation to the economy (OECD Conference for SMEs, pp. 1-3, 2004). Research Aim: The important element of enterprises is to induct the easy or smooth availability of the capital for their start up or growing business. The imperfect capital market and the economic turmoil have created barriers for insufficient external funding to the SMEs that has forced the government intervention in equity and debt market to provide funds and loans to their ventures (Graham, pp. 56-64, 2004). The main aim of the dissertation of th e proposal is to ‘Highlight and analyze the significance of the financing intervention within the small and medium sized enterprises and their attributes’. It also aims to analyze the following in order to bridge the gap between the finance providers and the small business. 1. Close analyses of the SMEs and their access to external finance. 2. The financial growth and government intervention in SMEs 3. The needs and supply capabilities between SMEs and financial intermediaries. Research Objectives: The objective of the dissertation includes the detail literature review and problems faced by SMEs deployment of financial funds. The purpose of this research is to recognize the factors influencing the financial decision making of SMEs and any other alternative option for funds. The study will also focus on critical factors discussed as below (Competition Commission, pp. 1-3, 2002): 1. Identify the policies and regulations for the provision of funds by the bank 2. Identify t he various sources of finance available to the SMEs and their significance. 3. Identify and deployment of options which are used to improve the burden of cost and accountability of revenue and profits for SMEs. Research Questions: Following are the questions that highlight the main reasons for the research dissertation: 1. What are the factors that are affecting the SMEs financial market and access

Bats Echolocation Essay Example for Free

Bats Echolocation Essay Echolocation is the art which is utilized by many animals in the detection of their pray and for navigational purposes. These animals are generally not equipped with eyes that are functionally advanced to the extent that makes them a good predator in their habitat. Common examples of such animals are Bats, dolphins, whales etc.   Such animals emit an ultrasonic signal into the environment and sense the signal that returns back after striking from the surroundings. This enables them to appreciate what waits ahead of them, its range, size etc. In short echolocation works exactly like modern day sonar in which the animal makes an estimate of the range of the pray by calculating the time interval between its own emission of the sound and the echoes that return back. Bats use echolocation signals that range in the frequency from   14kHz to 1000khz (Neuweiler 245) .These signals are thus well out of the range of human ear to hear which is capable to decipher audio signals falling between the frequency of 20 Hz -20,000 Hz .. Studies have indicated that bats have a very characteristic pattern of hunting by echolocation that can be divided into four phases namely search phase, approach phase, terminal buzz and the post buzz phase. All these phases differ in their band width and inter pulse duration. When a bat is in flying smoothly in search of it’s pray it is said to be in the search phase which is characterized by pulses which have a comparatively low pulse repetition rate, a higher pulse duration and inter-pulse interval . When the pray is detected the signal is changed to the approach phase in which the interval between the pulses decreases to about 33 ms. Just before the capture of the pray most of the echo locating bats emit a terminal buzz, which has further decreased inter-pulse interval. The terminal buzz phase can also be divided into a Buzz I and Buzz II phase. Irrespective of the fact that a prey capture attempt is successful or not the same pattern of phases is repeated again during the course a bat is flying in search of its pray. To tell more simply the usual signals in the search phase are well separated and have a lesser rate/sec as compared to the signals which are released when the bat has spotted and is just approaching its target.   The pattern of the phases are however different which would be discussed later in the same article. One may be wondering what makes these animals utilize such advanced mechanisms to hunt for their pray. The answer lies in the fact that bats are provided with a highly sensitive inner ear (The part of the ear that detects and transmits hearing impulses to higher centers in the nervous system). In the same way bats have a very advanced auditory cortex in order to interpret these signals (Grinnell 25). Numerous studies have been conducted on the echolocation pattern of the bats; below it the summaries of some selected studies which would enable the readers in a better understanding of the topic. Although it is an extremely vast topic yet every effort is made to provide the summaries of recent five researches 1) Effects of successful capture attempt versus unsuccessful capture attempt on post-buzz period: Adam et al in their study demonstrated the effect of a successful catch over an unsuccessful attempt on the post-Buzz period. Post Buzz period is the interval that follows the terminal buzz till the usual pattern of the pulses, search phase is restarted. According to this study the post-buzz phase was significantly greater after successful attempts as compared to unsuccessful attempts.206 ±112.3ms for successful attempts and 106.2 ± 83.3 ms for unsuccessful attempts. This increase in the post-buzz period has been attributed to time that is required in the handling of the pray. Similar studies have indicated increase in post-buzz time upon the successful capture of the pray (Kalko 225). However the post-buzz time was shorter in this study than that found in that found by Adam et al possibly due to the use of smaller insects. So the pray size is also a determining factor in the duration of post-buzz interval. Similar results were obtained by a study done by Annemarie, Vibeke and Jakob Tougaard from the University of Southern Denmark. In addition to the calculation of post-buzz time for successful and unsuccessful attempts they also calculated the post-buzz periods for touches also, i.e. when a bat is unsuccessful in capturing the prey yet its body parts slightly touch the prey in flight. Similar to the previous studies the post-buzz period was greatest in successful catches 272.2 ms and shortest in unsuccessful attempts, 117.9 ms and almost a middle value in case of touches i.e. 181.2 ms. 2. Effect of the size of prey on the bat’s response time One might think that it makes sense if we say that larger prays are detected from a longer distance as compared to prays of smaller size. But in actual studies this belief has been negated. One of the studies indicated that there was no significant effect of the size of the pray on the reaction time of bats. The mean time from detection till attempted capture was 604 ±141 ms (Britton 1796). Similar results were found by Acharya and Fenton in their study titled â€Å"Echolocation behavior of vespertilionid bats attacking airborne targets including arctiid moths† 3. Echolocation frequency of bat species and its relation with geographical habitat: In a lot number of studies the interesting phemenon of the relationship between specific bat frequencies to their habitat was demonstrated. Gareth Jones and Sofie M. V Parijs demonstrated the presence of both high frequency and low frequency Pipistrelus bats in Britain. The echolocation signals of the low frequency bats were never found to exceed 52 KHz while that of the high frequency bats were usually above 52 KHz (Jones 123). They attributed this frequency difference to their geographical habitats.   In recordings from Scotland the high frequency bats which were found to be 71% clearly dominated the low frequency bats.   Thus it was concluded that in a particular geographical area different phenotypic bats having nearly similar echolocation frequencies of the same specie can exist and the change in frequency is not exhibited by the same phenotype which change its frequency according to ecological conditions. 4) Echolocation studies in Dolphins: Dolphins appear to have a lot more advanced echolocation system as compared to bats. They listen to their pray and then use echolocation signals to get more information about the pray (Harley 62). There is also a possibility that dolphins use echolocation signals for communication purposes as well this was proposed by Brownlee. Conclusion: Keeping in view the diversified studies that have been done on the echolocation patterns of bats one finds himself amazed to see what is known and highly curious about what is yet to be found out. Future works can target coding bat species according to their echolocation frequencies. Although this is not going to be an easy job but it is going to open windows to new dimensions of research. Through this coding an attribution to the geographical location of the bats can also be made.

Enzyme Activity As A Function Of Substrate Concentration Biology Essay

Enzyme Activity As A Function Of Substrate Concentration Biology Essay The effect of concentration on enzyme activity. It can be noted that both enzyme solution used had different results. Enzyme activity was greater when using the chicken liver rather than the cow liver. Generally the enzyme activity increases as the drops of the enzyme (concentration) increases. There was a significant increase when six drops of enzyme solution (chicken liver) was added. The height of the bubble rose to 4 cm. there was a steady increase between when 9-12 drops solution was added. A sharp increase occurred when 15 drops of enzyme solution was added. The height was recorded as 7.5 cm. There was no significant increase onwards When enzyme solution (cows liver) was added there was no significant increase in the first set of drops. The height was recorded to be 3.5 cm when 3 drops of enzyme solution was added. There was an increase from 3.5 to 4cm when 6 drops of solution was added. There were no further significant increases un adding the enzyme solution. Graph 2 shows the effect of temperature on enzyme activity. For this experiment an enzyme solution of cow liver was used. There was an increase in bubble height when the solution was placed at 25 C. There was a further increase in the height when the solution was placed at 50 C. The height was recorded as 4.2 cm. However at 70 C, there was no change. There was no evidence of bubbles suggesting that the enzyme had been denatured. EXPLANATION Generally enzyme activity increases with increasing temperature. However in this experiment there was an increase then a sudden drop in enzymatic activity. Enzymes require certain conditions to be effective in their functioning. Some require certain temperatures to function. A reason behind the denaturing of the enzyme at 70 C is that the temperature was too high for the enzyme to function and it denatured due to this. Factors Affecting Enzyme Activity Knowledge of basic enzyme kinetic theory is important in enzyme analysis in order both to understand the basic enzymatic mechanism and to select a method for enzyme analysis. The conditions selected to measure the activity of an enzyme would not be the same as those selected to measure the concentration of its substrate. Several factors affect the rate at which enzymatic reactions proceed temperature, pH, enzyme concentration, substrate concentration, and the presence of any inhibitors or activators. Temperature Effects http://www.worthington-biochem.com/IntroBiochem/images/ie21.gif Like most chemical reactions, the rate of an enzyme-catalyzed reaction increases as the temperature is raised. A ten degree Centigrade rise in temperature will increase the activity of most enzymes by 50 to 100%. Variations in reaction temperature as small as 1 or 2 degrees may introduce changes of 10 to 20% in the results. In the case of enzymatic reactions, this is complicated by the fact that many enzymes are adversely affected by high temperatures. As shown in Figure 13, the reaction rate increases with temperature to a maximum level, then abruptly declines with further increase of temperature. Because most animal enzymes rapidly become denatured at temperatures above 40Â °C, most enzyme determinations are carried out somewhat below that temperature. Over a period of time, enzymes will be deactivated at even moderate temperatures. Storage of enzymes at 5Â °C or below is generally the most suitable. Some enzymes lose their activity when frozen. Effects of pH Enzymes are affected by changes in pH. The most favorable pH value the point where the enzyme is most active is known as the optimum pH. This is graphically illustrated in Figure 14. http://www.worthington-biochem.com/IntroBiochem/images/ie22.gif Extremely high or low pH values generally result in complete loss of activity for most enzymes. pH is also a factor in the stability of enzymes. As with activity, for each enzyme there is also a region of pH optimal stability. The optimum pH value will vary greatly from one enzyme to another Enzyme Concentration In order to study the effect of increasing the enzyme concentration upon the reaction rate, the substrate must be present in an excess amount; i.e., the reaction must be independent of the substrate concentration. Any change in the amount of product formed over a specified period of time will be dependent upon the level of enzyme present. Graphically this can be represented as: http://www.worthington-biochem.com/IntroBiochem/images/ie09.gif These reactions are said to be zero order because the rates are independent of substrate concentration, and are equal to some constant k. The formation of product proceeds at a rate which is linear with time. The addition of more substrate does not serve to increase the rate. In zero order kinetics, allowing the assay to run for double time results in double the amount of product. The amount of enzyme present in a reaction is measured by the activity it catalyzes. The relationship between activity and concentration is affected by many factors such as temperature, pH, etc. An enzyme assay must be designed so that the observed activity is proportional to the amount of enzyme present in order that the enzyme concentration is the only limiting factor. It is satisfied only when the reaction is zero order. Enzyme activity is generally greatest when substrate concentration is unlimiting. Effects of Inhibitors on Enzyme Activity Enzyme inhibitors are substances which alter the catalytic action of the enzyme and consequently slow down, or in some cases, stop catalysis. There are three common types of enzyme inhibition competitive, non-competitive and substrate inhibition. Most theories concerning inhibition mechanisms are based on the existence of the enzyme-substrate complex ES. Competitive inhibition occurs when the substrate and a substance resembling the substrate are both added to the enzyme. A theory called the lock-key theory of enzyme catalysts can be used to explain why inhibition occurs. The lock and key theory utilizes the concept of an active site. The concept holds that one particular portion of the enzyme surface has a strong affinity for the substrate. The substrate is held in such a way that its conversion to the reaction products is more favorable. If we consider the enzyme as the lock and the substrate the key the key is inserted in the lock, is turned, and the door is opened and the reaction proceeds. However, when an inhibitor which resembles the substrate is present, it will compete with the substrate for the position in the enzyme lock. When the inhibitor wins, it gains the lock position but is unable to open the lock. Hence, the observed reaction is slowed down because some of the available enzyme sites are occupied by the inhibitor. If a dissimilar substance which does not fit the site is present, the enzyme rejects it, accepts the substrate, and the reaction proceeds normally. ACTIVE SITE This is the part of an enzyme or antibody where the chemical reaction occurs SUBSTRATE In biochemistry, a substrate is a molecule upon which an enzyme acts. Enzymes catalyze chemical reactions involving the substrate(s). In the case of a single substrate, the substrate binds with the enzyme active site, and an enzyme-substrate complex is formed. The substrate is transformed into one or more products, which are then released from the active site ENZYME SUBSTRATE COMPLEX This is when the substrate binds reversibly to the enzyme forming a complex ANABOLISM Anabolism, or biosynthesis, is the process by which living organisms synthesize complex molecules of life from simpler ones. Anabolism, together with catabolism, are the two series of chemical processes in cells that are, together, called metabolism. Anabolic reactions are divergent processes. That is, relatively few types of raw materials are used to synthesize a wide variety of end products. This results in an increase in cellular size or complexity-or both. Anabolic processes produce peptides, proteins, polysaccharides, lipids, and nucleic acids. These molecules comprise all the materials of living cells, such as membranes and chromosomes, as well as the specialized products of specific types of cells, such as enzymes, antibodies, hormones, and neurotransmitters. CATBOLISM Catabolism, the opposite of anabolism, produces smaller molecules used by the cell to synthesize larger molecules, as will be described below. Thus, in contrast to the divergent reactions of anabolism, catabolism is a convergent process, in which many different types of molecules are broken down into relatively few types of end products. ..

Graduation Speech :: Graduation Speech, Commencement Address

The great big orange doors. The doors that we have grown so fond of during our four-year stay at Tropics High School -- the cafeteria doors. In an attempt to get to the Commons a split second faster than the person next to you, how many times have you opened those orange doors so hard and fast that you've gone BAM! and heard a response of a groan ... OW! Then in reaction to the yelp, you turn to see a boy with a freshly swollen red spot right in the middle of his forehead. "Sorry," you say with a cheesy grin and you skidaddle away as fast as you possibly can. You never see this boy ever again, except in the most random places and though you don't know his name, you'll always remember to never open the big orange door so fast and so hard ever again. As insignificant as he was in your life, he has taught you a lesson. Or how about the time at your first pep assembly when everyone around you is on their feet screaming at the top of their lungs to "Go Fight Win" and you, a timid, shy freshman, sat awkwardly not knowing what to do. Deep inside, you know you want to get up and be peppy, but a great fear of looking like a total loser prevents you from doing so. However, as you looked around and saw the spirit of the crowd, the pride in their eyes, and the energy pumping through the entire gymnasium and you thought to yourself, "What the heck!?!" Then you got up and cheered like the rest of your fellow classmates. Every person in that gym showing his or her Royal spirit influenced you to get involved. Because of that single decision, maybe later in your high school career you decided to become a cheerleader or even to help rally up the students at another pep assembly. Everything happens for a reason. And everyone that comes into your life, even the most random people who you thought were nothing more than just random people are there for a reason. They are there to serve some sort of a purpose, to teach you a lesson, or to help you figure out who you are or who you want to become. You never know who these people may be, possibly the closest person in your life or even a complete stranger, but when you lock eyes with them, you know at that very moment they will affect your life in some profound way.

The New Deal Coursework

The New Deal was set up by Franklin D. Roosevelt when he became president of the United States of America in March 1933. Roosevelt introduced the New Deal to stabilise the USA, focusing on his aims that he put forward in his inaugural speech. Roosevelt made his inaugural speech in March 1933, declaring his main aims that he planned to achieve during his time as President. During his speech Roosevelt said: â€Å"The only thing we have to fear is fear itself.† He said this because he wanted to assure the American citizens that he could reform the current depression in the USA and make sure no such crisis could happen again in the future. He wanted to regain the American people's confidence in that the problems caused by the Great Depression should no longer be feared because he had a plan to resolve the bad effect of the depression on his country. Roosevelt said that he aimed to make better use of natural resources, and to lower unemployment figures by providing jobs for thousands of people. He also said that he was aiming for the protection of people's savings and property, a redistribution of the land for those less privileged and to provide aid to the ill, elderly and unemployed. Roosevelt was granted one hundred days of broad executive power so that he could achieve his aims by passing laws quickly without having to put them through the government. With this power Roosevelt set up the â€Å"Alphabet Laws† that were combined to form the New Deal. The different laws he passed allowed him to achieve the aims that he had proposed in his inaugural speech. To accomplish his first aim of restoring confidence in the American citizens, Roosevelt came up with the idea of the â€Å"fire side chat†. The fire side chat was a radio show that Roosevelt would speak on every night, in a bid to convince Americans that he would make sure that America recovered fully from the Great Depression. Because the fire side chat was a daily occurrence, it could been seen as a form of propaganda but the radio shows did in fact give confidence to Americans in the way that they he made people believe that he would keep the promises he made to help America recover. One of the first of the Alphabet Laws that Roosevelt set up was The Emergency Banking Act. The Emergency Banking act was, to all intents and purposes, a four-day bank holiday; when all the banks were declared financially secure they were allowed to be reopened but those which were not were closed. Roosevelt set this act up to restore the Americans' faith in the dollar and to systematize America's economic situation. The Emergency Banking Act abolished Americans fears that their savings were not secure and let them put their trust back into the banks where they kept their money. Another program that Roosevelt set up was the Federal Emergency Relief Administration which was established to provide benefits for the unemployed. The basis of the program was that the government would give a dollar for every three dollars that the state spent; this was supposed to give people confidence that the unemployed would be given enough money to live on until a job opportunity came about. The fact that the Government was showing interest in the well-being of American people, made people believe even further that it was a strong, caring government system that took into account minorities and those in need. The Federal Emergency Relief Administration was later changed to the Civil Works Administration which was a project set up with five hundred million dollars backing from the Government, which was spent on public work schemes. It gave hundreds of people jobs all across America on developments such as road works and building important public buildings such as airports and sc hools. The Labour Relations act was brought about to give employees and workers across America the reassurance that they had worker's rights and the freedom to back themselves against unfair dismissal by their employer. The Home Owners Loan Cooperation was set up to give Americans back the confidence that they were safe from being evicted from their own homes. It allowed people to take out loans so that they could pay rent until they came up with a better source of income. As well as the Civil Works Administration as a factor in achieving his aims of lowering unemployment figures, Roosevelt also set up the National Recovery Administration, the Works Progress Administration, and the Public Works Administration; all of which were work schemes that provided jobs for many people in all aspects of society from arts to agriculture. Other aims of Roosevelt were the redistribution of land and better uses of natural resources. Roosevelt set up The Civilian Conservation Corps (CCC), the Agricultural Adjustments Act and The Tennessee Valley Authority (TVA). The Civilian Conservation Corps was set up to protect the environment in many areas of the USA. As well as observations on plants and wildlife such as tree-planting and beekeeping, the CCC also built many trails and buildings in state and national parks and installed fences, and power and telephone lines. The Agricultural Adjustments Act aimed to prevent farmers from being evicted from their homes by introducing new crops to farming areas. The government would also buy a cow from a family farm and then have the meat sent back to family tinned, ready to eat. The TVA was set up in order to provide economic development in the Tennessee Valley, where many people were affected greatly by the Great Depression. It concentrated on building dams to prevent flooding and to regain land around the Tennessee River and also on electricity generation and the manufacturing of fertilizer as a source of income. Roosevelt also set up other organisations to tackle other problems such as The Social Security Act that gave aid to the ill, elderly and unemployed; and the National recovery Administration that ensured working conditions were acceptable for everyone and to abolish over working and child labour. In conclusion, Roosevelt covered all of his aims mentioned in his inaugural speech using his power to pass the Alphabet Laws in order to keep his promises that he made to the people of America. The features of the New Deal came together to successfully meet Roosevelt's initial aims as President, as he made a benefit of the environmental state of the USA by using natural resources to boost the economy and provide employment for many people, effectively killing two birds with one stone.
