Honor And Recognition For Defending The Freedom Of The...

Soldiers deserve honor and recognition for defending the freedom of the United States. They risk their lives so other Americans do not have to, and they are rightfully thanked for their work. Honoring soldiers is viewed as respectful and lets the soldiers know that Americans value their sacrifices for our country. However, for some people commending soldiers is often more about their own personal gain and self-esteem than about respecting the soldier. Honoring soldiers is often used as an excuse to boost popularity, increase personal satisfaction, and worst of all, to make money. Mention book In Ben Fountain’s Billy Lynn’s Long Halftime Walk, many people approached Billy to congratulate him for his service in Iraq. One lady talked to Billy about watching 9/11 on the news and proclaimed how proud she was that justice was being done (Fountain 44). She conveyed her thoughts concerning the war for a while before asking, â€Å"Which one are you?† to Billy, almost as if she really did not care about Billy as much as she did getting her thoughts on the war out to a soldier. After Billy introduced himself, the woman continued her spiel on how patriotic she and her daughter acted (Fountain 44). Throughout the time the woman spoke Billy, kept quiet and let her continue, a considerate act which showed Billy’s lack of interest in what the woman had to say. The woman talked to Billy mostly to boost her personal satisfaction and pride for her country, instead of to thank Billy forShow MoreRelatedThe Day Of The World War I1370 Words   |  6 Pagesallied nations and Germany.

Efficiency Wages Models of Unemployment †MyAssignmenthelp.com

Question: Discuss about the Efficiency Wages for Models of Unemployment. Answer: Introduction: The economy of Greece has been going through a lot of turbulence and its repercussions have affected many indicators of macroeconomics. Unemployment is one such macroeconomic indicator of the country which has been severely affected. The aim of this paper to answer questions related to the unemployment in Greece. The unemployment of Greece is measured by taking the percentage of the labours who are working out of the total workforce of the country. In the case of Greece, the unemployment has been similar to the figures of European Union as a whole till 2008 (Farber Valletta, 2015). However, due to the financial mismanagement and the crises after the year 2008 the unemployment rate fell sharply compared to the European Union. There are two types of problem in the country in terms of unemployment. First one is the long run unemployment which is also called the natural rate of unemployment. This is not the result of the mismanagement it has committed in the past. Another problem of the economy is the cyclical unemployment which fluctuates around the normal rate as a result of the changes in the business cycle and the national product of the economy. Menzio (2016) stated that negatively sloped GDP of the country also reflects in the employment of the country as well. According to the figure 2, the falling GDP of the country shrank the economy increasing the frictional unemployment in the economy. In the case of Greece, the unemployment rate is not measured correctly as it does not include many types of individual in the overall labour participation of the country. Kaplan Menzio (2016) pointed out that it does not include the individuals who have stopped looking for jobs. Taking advantages of inaccuracy the individuals, despite not being unemployed claims the benefits from government increasing the burden of the government even more. Since the financial crisis in the year 2008, the overall GDP of Greece started to fall at a steady rate. Hence the long term problem of the country in terms of unemployment is increasing normal rate unemployment which has increased to 20.1% in the year 2016. Apart from that, the short run short run cyclical rate of unemployment is also there relating to the fluctuations in the business cycle of the Greek economy. The main reason for the unemployment in case of Greece is the lowered foreign investment in the economy. Job market shrank following the crises survived by the country in the year 2008. Therefore the shortage of demand for labour is the main cause of unemployment in case of this country. The government of the country, in order to increase the labour productivity, introduced the efficiency wage in the year 2009. However, as the theory suggests the unemployment of the country increased more than the increase in the productivity of the labour. Frictional unemployment is the major component of severe unemployment in case of Greece. Since the dip in the GDP of the country, the average time to get a job has increased and hence the frictional unemployment increased. Structural unemployment in Greece arose as the labour requirement for unskilled labour reduced. These unskilled labours were of no match for the existing technical jobs of the economy leading to an increase in the structural unemployment. Currently, the unemployment figure of Greece stands at 20.1% which is very high compared to the other nations of the world. It is in equilibrium only because of the presence of demand for skilled labours. It is recommended to the government to increase government spending against increased inflation as it would stabilise the unemployment rate of the country. Reference Farber, H. S., Valletta, R. G.

Women in Ancient Israel A Contemporary View free essay sample

This paper analyzes critically the role and position of women in the ancient Israel with reference to Hebrew Bible/Old Testament and contemporary scholarly journals and books. The paper discusses the place of Israelite women in ancient days, her status and economic roles. The author states that the Israelite women could have been better, more productive citizens had their status and their environment been more favorable towards them. The author continues that understanding the role of Israelite women in ancient times has a significance place in understanding women in the modern world. She illustrates this by discussing the lives of Jewish women in the coal field economy and in the modern practices in Judaism. In the masterpiece by Adler, Engendering Judaism, the author skillfully explains the hardships faced by Israelite women and the obstacles that the Jewish feminists have had to overcome: Jewish law needed to be reconstructed to eliminate the ancient premise that women are subordinate to men, yet at the same time maintain the law. We will write a custom essay sample on Women in Ancient Israel: A Contemporary View or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page For without law there is no means to translate the stories and values of Judaism into action (Jones et al, 58) . Hence taking into account the authors opinion as well as what the biblical law stated above, it is evident that Israeli women were considered not only subordinate to Israeli men due to lack of women rights awareness and inaccurate interpretation of the Hebrew biblical context, it was strict adherence to the rituals, the olden days traditional laws and socio-economic rules that led to Israelite womens submissive attitude towards their male counterparts for rituals play a pivotal role in shaping our concepts, attitudes, emotions, behavior and social status. For a ritual is a spiritual ballet, it captures in symbols the emotions that go with an important life transition.

Taxation Law Practice Essay Example | Topics and Well Written Essays - 2250 words

Taxation Law Practice - Essay Example In Australia, income taxes are increasingly imposed with higher income earners paying a higher percentage than lower income earners (ATO, 2007) Where income is earned in the form of capital gains on prescribed assets, only half of the gain is measurable for Capital Gains Tax (CGT) purposes if it was held for at least 12 months. If the assets were held for less than 12 months, then it is fully measurable for CGT purposes. A person's principal place of residence however is exempt from CGT. Where income is earned in the form of capital gains on prescribed assets, only half of the gain is assessable for Capital Gains Tax (CGT) purposes if it was held for at least 12 months. If the assets were held for less than 12 months, then it is fully assessable for CGT purposes. A person's principal place of residence however is exempt from CGT. Medicare (National Health Insurance) is charged at a flat 1.5% rate. If you earn more than 50,000 and do not have private health insurance you are liable for an extra 1% of your taxable income. This extra charge is known as the Medicare Levy Surcharge. Companies and corporations pay tax on profits. Not just like personal income taxes which use a progressive range, corporate taxes in Australia are calculated at a flat 30% rate. Tax is paid on corporate income at the corporate range before it is distributed to individual shareholders as dividends. A tax credit called a franking credit is provided to individuals who receive dividends to reflect the tax already paid at the corporate level a process known as dividend imputation (ATO, 2007). GOODS AND SERVICES TAXES The Federal Government levies a multi-stage tax of 10% on the supply of most and services by entities registered for Goods and Services Tax (GST). There are lots of supplies which are GST-free just like many basic foodstuffs, medical and educational services, exports; input-taxed like residential accommodation, financial services; exempt similar to Government charges; or outside the scope of GST. The profit from this tax is disseminated to the States. State governments do not charge any sales taxes though they do impose stamp duties on a series of transactions (ATO, 2007). PROPERTY TAXES Local governments are typically funded largely by property taxes on residential, industrial and commercial properties. Aside from that, some state governments charge tax on land values for investors and primary residences of high value. The state governments also charge taxes on the transfer of property title and the registration of commercial leases. Fire Service Charges are also frequently applied to domestic house insurance and business insurance contracts. These charges are required under State Government law to assist in funding the fire services in each State (ATO, 2007). EXCISE TAXES Both the federal and state governments require excise

Via Dolorosa Research Paper Example | Topics and Well Written Essays - 1500 words

Via Dolorosa - Research Paper Example The physicality of this particular path and the unidirectional focus that Christ’s ministry had with regards to the very moment of undergoing the hardships leading up to and including crucifixion can be literally understood by journeying this physical path towards the atonement for sin. As such, it comes as little wonder why the Via Dolorosa has come to occupy such an important place in the hearts and minds of so many of the faithful around the globe. Firstly, though it might be tempting, the fact of the matter is that the Via Dolorosa did not exist in its current form until around the 18th century (Russell et al 784). What is meant by this is the fact that the path that Christ supposedly tread prior to crucifixion on Pottery was one that has been up for debate I scholars and theologians for many years. Perhaps more importantly to those within the Roman Catholic, Episcopal, or Anglican faiths are what are known as the â€Å"stations of the cross† (Denomme 37). ... 3 – Jesus falls for the first time, station 4 – Jesus meets his other, station 5 – Simon of Cyrene helps Jesus to carry the cross, station 6 – Veronica wipes the face of Jesus, station 7 – Jesus falls the second time, station 8 – Jesus meets the women of Jerusalem, station 9 – Jesus falls the third time, station 10 – Jesus’ clothes are taken away, station 11 – Jesus is nailed to the cross, station 12 – Jesus dies on the cross, station 13 – Jesus is taken down from the cross, station 14 – Jesus is laid in the tomb. As with any form of research, whether Biblical or scientific, the Via Dolorosa has come to be more completely and effectively understood over the past several hundred years. As continued scientific and archeological discovery took place in the Holy Land, the centuries of changes that had affected the landscape and impacted upon the existence of certain types and directions of roads th rough the city of Jerusalem came to be understood in a more complete manner. As such, the mere existence of changes to the route of the Via Dolorosa does not in and of itself denote that the path itself is somehow contrived. Rather, it has merely come to be understood in a more effective and complete manner as a result of the subsequent understanding of what roads and paths existed in what times (Kline 49). Moreover, due to the fact that Jerusalem has exhibited nearly continual residency by some people group or another over the nearly 3000+ years of its existence, it is not a precise or exact science to specify to any level of absolute certainty what existing and non-existing roads or paths can or should be included in the modern day interpretation of the Via Dolorosa. However, that being said, the actual path itself, barring some almost certain

British Airways and its predecessor companies Essay

British Airways and its predecessor companies - Essay Example Two other airlines, Handley page, and Instone, were established using modified bombers. The three companies underwent a period of great difficulty, especially competition from French airlines, which were cheaper. To solve these problems, they merged to be joined later by British Marine Air Navigation, forming Imperial Airways. Imperial Airways began local and overseas flights immediately, flying as far as Egypt and India with a crew of 250 and a fleet of 18 crafts (Gaskell, 2010). This paper is an essay on British Airways. Later, Imperial Airways was a Brisbane, Australia route, whose duration would take grueling 12 days. The new airline added new planes such as the short S.23 C-class model, which signified that the airline was growing, as was a new carrier British Airways limited (Gaskell, 2010). After the start of the 1st World War, these two merged to form British Overseas Airways Corporation, which re-started its transatlantic flights after the war ended. In addition, they create d the BEA, a new airline to handle the European flights. At this point, the carriers needed to order new and more efficient aircraft. BOAC consequently ordered the Boeing Strato-cruiser, the Lockheed Constellation, and a Rolls-Royce engine equipped version of the DC-4. It did not take long before they ordered a jet plane, the De Havilland Comet, which dramatically reduced the length of trans-Atlantic flights (Marriott, 2010). The early 60’s saw BOAC order the Rolls-Royce Conway engine driven 707-436 to tide over until the VC-10s were ready. By 1970, with the first 747 and rapid growth, BOAC and BAL were ready to merge and work as one, establishing British Airways in 1976. BA’s most crucial year was 1976; it had a partnership with Concorde, coupled with big fleets of Lockheed TriStar and Boeing 747.

The History Of Strategic Marketing Management Marketing Essay

The History Of Strategic Marketing Management Marketing Essay In order to pursue an effective strategic marketing management in organisation, it is necessary to grasp all of the internal and external areas and domains that may lead to successful implementation of the marketing initiatives. Realising the fact that strategic marketing management is quite a broader field, todays marketing professionals have to consider a number of those critical factors and aspects that turn the organisation into huge success, or an absolute failure. The word strategic is, itself, suggests scrupulous planning and policymaking, because these are the overall effects of strategic marketing management that play a major role in long-term growth of an organisation. Section 1 Strategic marketing plays a fundamental role in any organisation. Strategic marketing mainly helps in devising positioning strategies in relation to the market being targeted, but beyond all that, strategic marketing, primarily, helps in analysing the targeted market segments in view of the market competition with all well-established, mature and even immature products and services. After segmenting the market, a strategic marketer meticulously devises relationship strategies with those of the consumers or customers being aimed at. Strategic marketing, then, creates effective and the most relevant distribution and pricing strategies, followed by formation of exclusive strategies for advertising and promotional plans and strategies. Moreover, a strategic marketer, also, formulates business development and research strategies in a way that, ultimately, fosters long-term organisational growth and business sustainability. This is, again, the role of strategic marketing to pursue a set of strategies for marketing research too. Cosse and Swan (1983) found one major problem in marketing planning was that US product managers lacked the strategic orientation required by strategic planning. (Piercy, Morgan, 1990, 128) Usually there are three fundamental processes involved in strategic marketing, wherein planning is the leading and most significant process, followed by the implementation and control accordingly. Each of these elements is important not only for desired success of entire marketing strategies, but for an all-inclusive organisational growth. Exclusively for the planning process, organisation needs to perform a SWOT analysis first keeping view both internal and external factors. A marketing audit can help identify target markets for your firm. A marketing audit evaluates various internal and external components. (Caragher, 2008, 59) Objective and goal setting is also its main part, as it helps determine the market and consumer segmentation, as well as the role of strategic marketing management. Implementation is the process that brings the planning into action, and the control phase helps organisations in evaluating the planning process. As per their functions, strategic marketing and corporate strategies are interlinked with each other, and organisation can never achieve their role by dealing with these elements separately. According to Tom Connora (2007), a corporate strategy is more than marketing alone. (Connora, 2007, 369) A marketing strategy needs to be aligned with the corporate strategy of the organisations, while corporate strategies remain ineffective if its managers take the process of strategic marketing for granted. Corporate strategies mainly determine the direction of the organisations, where marketing is supposed to follow the same direction. Although marketing must be the principal channel of market knowledge this must be combined with and balanced by knowledge provided by the other business functions of the organisation. Thus a transcendent organisational view emerges which, it is suggested, is the true basis for corporate strategy. (Connora, 2007, 369) This is necessary to craft a comprehensive corporate strategy for the organisational success, but this cannot be completed without creating a strategic marketing plan. Knowing the fact that marketing has a lions share in entire business development of an organisation, effective corporate strategy entails a flexible structure enabling marketing strategies to freely perform in the market. The same goes for the marketing gurus in any organisation, as they can never achieve their goals and objectives if their strategies are not aligned with those of the features clarified in their main corporate strategies. Both of these factors go alongside each other. Section 2 Utilised in strategic marketing planning, various models offer numerous benefits and advantages to organisations. The first benefit of using models is that it enables strategic marketers to find out substitutes and alternatives, during strategic marketing planning. Consequently, utilisation of these models enhances the decision making capabilities for strategic marketers, helping in making due decisions without unnecessary delays. Through these models, organisations get timely information as well, thus making them capable to perform market forecasting more accurately. This well-timed information appears to be an asset in strategic marketing planning, as this information is, always, accessible and far-reaching. By using these models, organisations derive benefit from flexibility in framing the control reports as well. There is a strong link between employing strategic marketing and strategic positioning. Theoretically, strategic positioning helps in product placement in a way that makes the product easily available in the target market. In a word, strategic positioning stands for the strategic convenience in strategic marketing management, because strategic marketing revolves around positioning. Marketing strategies should respond to the distinctive characteristics and desires of its target market. Strategic positioning differentiates a business from its competitors by uniquely serving its target market. A strategic marketing plan should position a business so that its target market perceives that the business serves them and them alone. (Kruger, 2011) This is also the strategic positioning which helps in formulation of segmentation targeting. Strategic positioning also helps in multiplying the returns on existing marketing plans and strategies. Entire marketing strategies will bring no positive results if the crucial aspect of strategic positioning remains avoided. This is because strategic positioning plays a significant role in promoting the ratio of customer loyalty and profitability as well. Merits of strategic positioning with respect to strategic marketing development are includable. First and foremost, it helps determine the target audiences according to the demographics of the target market. It helps in determining the way an organisation wants to place its products or services in the market after meticulous categorisation and classifications. The employment of positioning strategies that leads to creating a position in the marketplace is undertaken over time through deployment of marketing practices including advertising, public relations, promotion, sales inducing efforts, publicity, etc., brand management, firm image and reputation, product development, and cost controls.(Blankson et. al., 2008, 2) Accurate projection of the sales can never be achieved by skipping the inevitable element of strategic positioning. As organisations are never supposed to please all and sundry under the sun, there must be a smart positioning that may your products to customers found in a predefined market. Product positioning has emerged as a separate field in the world of strategic marketing management. Despite offering a highly enriched product to consumers, this is the meticulous positioning of the product which will decide its acceptability and penetration into the market. There are various examples corroborating the significance of strategic positioning of any brand or service e.g. Coca Cola, Nestle, Wal-Mart, McDonalds, and FedEx, and GE (General Electric), and many more. Strategic positioning, also, depicts the in-depth market knowledge of organisation, as positioning is, usually, done with the help of market research, market intelligence and data gathering. Section 3 To ascertain growth opportunities in a market to the maximum, I would utilise a set of appropriate marketing techniques that includes branding, offerings, packaging and labelling, value additions, and environmental scanning. In details, I would, first, utilise the branding technique in order to differentiate the product than those of the products being offered by the competitors in the same market. Then here comes the phase of packaging and labelling that focuses on attractive presentation of the products through catchy designs and colour schemes etc., which is, further, supplemented by the labelling tool. Successful marketing strategies have always been based on unique insights into consumer behaviour, generalizations of successful tactics, brilliant advertising ideas, and technical innovations as well as market segmentation research. (Gibson, 2001, 1) The tool of offering will be, also, utilised to find out the best solution addressing the customers problems and concerns in comparison with other products available. Being a strategic marketing manager, I will, also, concentrate on value addition so as to multiply the demand and recall of the product in the real market by the targeted consumers and customers. Additionally, I will perform an essential environmental scanning by collecting the data in way that brings us exceptional growth via strategic marketing. In any market, an effective utilisation of market strategy options is taken as the fundamental and crucial phase in entire strategic marketing management. As the battle for the wallet of the emerging-market consumer shifts into higher gear, companies that think about growth opportunities at a more granular level have a better chance of winning. (Atsmon, Kertesz Vittal, 2011, 60) Being a strategic manager, I will use the same in accordance with the four Ps model which entails 1-Product, 2-Price, 3-Placement, ad 4-Promotion. This will be, accordingly, done in consideration of organisational strategies and its accessible resources so that it helps in maintaining the ratio of profitability. The same, also, fortifies the products being sold in the market, thus facilitating standardisation to a large scale. Most of the time, companies and organisation find it difficult to standardise their own marketing and positioning standards and values. Particularly on the consumer side, this standardisation is necessary, as this builds up the confidence of the target customers, and increases the customer loyal to a large extent. Standardisation is an on-going journey, where organisations need to perform the similar way to retain their existing customer base. The most important factors is that this is, also, inevitable to standardise their marketing and positioning efforts, as not all companies can maintain their level of standardisation being offered to their customers. For a defined market, creation of appropriate strategic marketing objectives is considered as a daunting task for the marketers. In fact, strategic marketing objectives are formed in a way that creates a constant need of the particular product in the market, and this objective can never be achieved with flawless standardisation. Section 4 A marketing strategy is always dependent upon various environmental factors. Starting from the political situation of the country to its sluggish economic trends, these environmental factors help in devising a win-win marketing strategy that may successfully address all of these external environmental factors all at once. The function of marketing strategy deals with determining the nature, strength, direction, and interaction between marketing mix elements and the environmental factors in a particular situation. (Akinyele, Samuel Taiwo 2010, 24) Other than law and order situations, absence of competitor in the market affects the sales of a particular product, as well as existing purchasing power of the customer, also, determines the products penetration in the concerned market. Organisations also need to keep up with those of the technology changes and up-gradations occurring in the outside word. I, being a marketing manager, will conduct an internal analysis in order to identify current strengths and weaknesses in a marketing strategy, and this will be done by evaluating the strengths and weakness of the market strategy. Strength of a market strategy is determined by evaluating the effectiveness of the promotional mix. This is, further, followed by knowing the current positing of product placement in the market, mostly relying upon quality of the products, effective branding, packaging and labelling, as well as variety of offerings made for the target consumers and customers. The most important components related to niche marketing include: Firm profile (Organisation charts, billing rates, financial statements); Partner profile (partners personal and professional objectives, firms specialties, age and tenure with the firm); and SWOT analysis (Strengths, weaknesses, opportunities and threats). (Caragher, 2008, 59) This is, also, fundamental to knowing the weakness of the marketing strategies being implemented, and this is done by analysing various factors critically and neutrally. This may pertain to the lack of innovation, ineffective or irregular communication, and wrong selection of marketing and advertising channels, along with imperfect or untimely distribution of the products etc. The penetration and popularity of the digital media is one of the emerging themes in the world of marketing. As per my response to this rapidly emerging marketing theme, I propose the strategic and well-planned utilisation of the social and digital media after thorough research and investigation. This response will be tinged with usage of latest technological tools and methods, as innovative marketing enables companies to churn out maximum results in form of overall business development and profitability.

A comparison of Kern County and Sierra Nevadas Essay -- essays researc

Of Oak Stumps and Oil Pumps   Ã‚  Ã‚  Ã‚  Ã‚  The Great Sierra Nevadas and Kern County are two strikingly different faces of California. The Sierra Nevadas, a natural refuge for a sizeable number of California’s wildlife, houses opportunities for harvesting lumber, a spiritual place to camp or hike on, and simply as an aesthetic marvel in contrast to LA’s bustling city streets. Kern County’s industrial benefits come from Black Gold, oil. The Kern River discovery started an oil boom, and a forest of wooden derricks sprang up overnight. Kern County resembles a dry rocky land. A noticeable lack of movement except for a thousand oil pumps bowing incessantly like Buddhist monks in a trance of prayer. These two places are similar in that they are resource-full and beauties to behold, but, The foothills of the Sierra Nevadas outweighs Kern County through its natural majesty, its beauty; Kern County on the other hand, has more financial worth because of its rich oil deposits which give it its ind ustrial feel.   Ã‚  Ã‚  Ã‚  Ã‚  The inhabitants of the Sierra Nevadas are inspired to live in a nature filled environment, away from busy city streets and bright neon lights. The Great Sierra’s geography outlines its beauty by being surrounded with a dry, hardwood conifer forest, drought-resistant shrubs and bushes in the canyons; as is described by Gary Snyder in â€Å"Cultivating Wilderness† (Snyder 256). This place brings a feeling of growth and provides agricultural ...

How Does Temperature Affect Lipase

How does temperature affect the rate of reaction for Lipase? As the temperature increases, so will the rate of enzyme reaction. However, as the temperature exceeds the optimum the rate of reaction will decrease. I predict that at temperatures above 70 °C the enzyme lipase will become denatured and at temperatures below 10 °C the enzyme will become inactive. Since lipase operates within the human body I’d also predict that its optimum temperature would be around human body temperature which is approximately 37 °C.I predict that before the optimum temperature the rates will gradually increase and preceding the optimum there will be a drastic decrease in rate until the enzyme is denatured. I predict that the rate of enzyme activity at 45 °C will be half that of 30 °C. I predict that the rate of enzyme activity at 45 °C will be half that of 30 °C. Diagram courtesy of: http://www. rsc. org/Education/Teachers/Resources/cfb/enzymes. htm Diagram courtesy of: http://www. rsc. org/Education/Teachers/Resources/cfb/enzymes. htmIn my controlled assessment I will be investigating the activity of lipase on milk fat at various temperatures so that I can then find an accurate temperature as to when the enzyme works at its optimum; when it becomes inactive and when it denatures. To find when the enzyme denatures is to find out when the bonds of this protein disintegrate and henceforth disable the enzyme from being of any further use. When these bonds break, the protein starts to unfold and loses some its properties. For example, a denatured protein usually becomes less soluble. As an enzyme, it will lose its ability to function as a catalyst.If the stress that is causing the denaturation continues, other changes may occur. Now that the normal structure of the protein is gone, new bonds may be formed, giving it a different shape. The bonds broken in a denatured enzyme is that of which links the polymers to form the amino acids. This means that if lipase were to denature at the higher temperatures it will then cause inactivity in breaking down the fat of the milk hence leaving the unchanged. In this investigation, however, there are numerous factors as to what can affect the investigations results.First of all, the temperature of the room can play a role in altering the results as it can change the temperature of both the solution and lipase. Moreover if one were to move the solution or lipase to another part of the room, or to carry out the investigation on a different day, the temperature surrounding the solution and lipase will change and henceforth change the temperature of the solution and lipase. Secondly, if the temperature of the water bath isn’t precisely the temperature it is supposed to be then, as expected, would change.Thirdly, the age of the contents can affect the concentration of the substrates which would then decrease the rate of reaction with lipase. Finally, there is the factor of human error, as we may not be capable of making perfect measurements consistently the amounts of each component will inevitably change, which would in effect change the results. Of this investigation our independent variable will be the rate of reaction, which we will measure by timing how long it would take for the solution to turn white after having the lipase poured in.Our dependent variable will be the time it takes for the solution to turn pink after having the lipase poured in. Our controlled variable is that of will be all other factors. Enzyme Diagram courtesy of http://students. cis. uab. edu/clight/finalprojectwhatisanenzyme. html Diagram courtesy of http://students. cis. uab. edu/clight/finalprojectwhatisanenzyme. html An enzyme is a molecule that changes the speed of reactions. Enzymes can build up or break down other molecules. The molecules they react with are called substrates; enzymes are catalysts.An enzyme works by allowing a substrate, or multiple substrates, to enter the active site, which is where the reaction takes place, and then to exit in either more or less pieces then it was when it first entered. The active site is unique to a specific substrate which means that other substrates cannot react with that enzyme unless the enzyme is modified. [An active site can be altered by a non-competitive enzyme which encircles the enzyme and alters the shape of the active site which could be very dangerous. ] Diagram courtesy of: http://www. wiley. com/college/boyer/0470003790/reviews/kinetics/kinetics_effec ors. htm Diagram courtesy of: http://www. wiley. com/college/boyer/0470003790/reviews/kinetics/kinetics_effectors. htm Note that the enzyme remains unchanged so that more of the some substrates can react. Note that the enzyme remains unchanged so that more of the some substrates can react. Structure Proteins are polymers made by joining up small molecules called amino acids. Amino acids and proteins are made mainly of the elements carbon, hydrogen, oxygen and nitrogen. Pro tein Protein Amino Acid Amino Acid Each gene acts as a code, or set of instructions, for making a particular protein.They tell the cell what to do, give its characteristics, and determine the way its body works. Each protein has a unique sequence of amino acids. This means that the number and order of amino acids is different for each type of protein. The proteins fold into different shapes. The different shapes and sequences give the proteins different functions, e. g. keratin are a fibrous protein found in hair and nails. If the gene has even the slightest of disorder within its sequence it could lead to an inaccurate order of amino acids and so a faulty protein or in our case faulty enzymes.Substrate concentration An enzyme has an active site where it binds the molecule (or molecules) it acts upon; the enzyme then catalyses a chemical reaction involving that molecule (or those molecules). That molecule (or those molecules) is called the enzyme's substrate. So the substrate concen tration is the concentration of the molecules an enzyme works on. Diagram courtesy of http://biochemistryquestions. wordpress. co m/2008/07/15/induced-fit-model-of-enzyme-substrate-interaction/ Diagram courtesy of http://biochemistryquestions. wordpress. o m/2008/07/15/induced-fit-model-of-enzyme-substrate-interaction/ In general, if there is an increase in substrate concentration, then more enzymes will be catalysing the chemical reaction and the overall rate of reaction will increase. It will continue to increase until all enzymes are actively binding substrate (called saturation), at which point no further increase in rate can occur, no matter how high you raise the substrate concentration. In my investigation into enzyme response to temperature this graph will be of relevant. Diagram courtesy of: http://www. sc. org/Education/Teachers/Resources/cfb/enzymes. htm Diagram courtesy of: http://www. rsc. org/Education/Teachers/Resources/cfb/enzymes. htm Denatured Denatured Denaturing Denaturing Less kinetic energy so the reaction slows down. Less kinetic energy so the reaction slows down. This graph illustrates the response that rate of enzyme activity has at various temperatures. At lower temperatures the rate is very low as there isn’t enough kinetic energy for the enzyme to work at its optimum, then you of course have the enzymes temperature optimum where the enzyme works best at.Finally you have the denaturing of the enzyme which eventually halts with the enzyme being completely denatured where it then will never have any activity. Collision Theory For a chemical reaction to occur, the reactant particles must collide. But collisions that do not have enough energy do not produce a reaction. The particles must have enough energy for the collision to be successful in producing a reaction. The rate of reaction depends on the rate of successful collisions between reactant particles. So the less successful collisions that occurs the less products created. D iagram courtesy of: ttp://www. worthington-biochem. com/introbiochem/tempeffects. html Diagram courtesy of: http://www. worthington-biochem. com/introbiochem/tempeffects. html The reason as to why particles may have or may not have enough energy to create products depends on the amount of kinetic energy in the particles. Hence why at lower temperatures the enzyme becomes inactive as there isn’t a high enough temperature to create the necessary kinetic energy to create the products. As the temperature increases so does the rate which is due to more kinetic energy and hence more successful collisions. H An enzyme can also denature upon extreme pHs. with the extreme pH’s being 1 and 14, the enzyme would denature due to the hydrogen acids within the pH’s damaging the amino acid bonds within the enzyme. By damaging these bonds, the amino acids break apart, this in turn means that the enzyme’s active site will lose its shape, resulting in the denaturing of the enzyme. Henceforth, the optimum pH is in the middle of the pH spectrum as neutral pHs are unable to damage the bonds of the amino acids keeping the enzyme capable of reaction.Preliminary Method a. Get a test tube for each temperature being investigated. b. Add 5 drops, using a pipette, of phenolphthalein to the test tube. c. Measure out 5 cm3  of milk using a measuring cylinder and add this to the test tube. d. Measure out 7 cm3  of sodium carbonate solution using another measuring cylinder and add this to the test tube. The solution should be pink. e. Place a thermometer in the test tube. f. Place the test tube in a water bath and leave until the contents reach the same temperature as the water bath. g.Remove the thermometer from the test tube and replace it with a glass rod. h. Use the 2 cm3  pipette to measure out 1 cm3  of lipase from the beaker in the water bath for the temperature you are investigating. i. Add the lipase to the test tube and start the stopwatch. k. Sti r the contents of the test tube until the solution loses its pink colour. l. Stop the clock/ watch and note the time in a suitable table of results. *A control was also investigated by having a test tube with the sodium carbonate, phenolphthalein and milk but without the lipase.This is to test as to whether the solution would turn from pink to white regardless of whether the enzyme was present or not. This was the original method which was used to carry out the preliminary investigation, however upon consideration it was decided that for the real practical a slightly alternate method should be used. In our edited method we made the changes of firstly, on putting the lipase into the water bath, this was because heating up the solution instead is to investigate the effects of the temperature of the solution as oppose to how the temperature of the enzyme effects.Secondly it was decided upon that we would not stir the contents for two reasons: firstly because by stirring the solution it spread the lipase around more which in effect speed the reaction up so much that it was impossible to time; secondly, by stirring the contents it often made the solution over flow which both made a untidiness and caused the volume of the contents to decrease. Finally it was decided that we were to limit the amount of temperatures being investigated as temperatures below 22? the enzyme was inactive hence taking too long to record the time it took for the solution to turn white, at temperatures over 55? c the enzyme, the lipase enzyme would be denaturing hence taking too long to be able to record as well. Final Method a. Get a test tube for each temperature being investigated. b. Add 5 drops, using a pipette, of phenolphthalein to the test tube. c. Measure out 5 cm3  of milk using a measuring cylinder and add this to the test tube. d. Measure out 7 cm3  of sodium carbonate solution using another measuring cylinder and add this to the test tube.The solution should be pink. e. Plac e a thermometer in the test tube. f. Place the test tube, containing only the lipase enzyme, in a water bath and leave until the contents reach the same temperature as the water bath. g. Remove the thermometer from the test tube. h. Use the 2 cm3  pipette to measure out 1 cm3  of lipase from the beaker in the water bath for the temperature you are investigating. i. Add the lipase to the test tube and start the stopwatch. k. Stop the clock/ watch and note the time in a suitable table of results. A control was also investigated by having a test tube with the sodium carbonate, phenolphthalein and milk but without the lipase. This is to test as to whether the solution would turn from pink to white regardless of whether the enzyme was present or not. Such changes were made in an attempt to improve the validity of the investigation. As is in the nature of an investigation it is impossible to make the results completely accurate and precise. What we can do however is improve the reprod ucibility and reliability of our results by repeating the test multiple times.Risk Assessment Substance| Hazard| Risk| Risk rating*| Emergency action| Phenolphthalein | LOW HAZARD| Although it is not hazardous one should take precaution avoiding skin contamination. | 1| If in contact with eyes then flood eyes with water to wash it out. | Lipase| HAZARD| If in contact with skin it can cause an itch. If someone were to have an allergic reaction to lipase it could cause symptoms such as rashes. | 1| Seek emergency assistance if you believe you are having an allergic reaction to lipase. However wash it off as quickly as possible. Sodium Carbonate| IRRITANT| Sodium carbonate contributes to three major hazards: skin irritation, eye damage and internal effects. | 3| If swallowed, drink two or more glasses of water or milk. If in contact with skin use a cloth to wipe the sodium carbonate or rinse with water and if contact with eyes rinse thoroughly. | Milk| LOW HAZARD| If in contact with sk in it can cause an itch, however some people may have an allergic reaction to the substance. | 2| Acting in accordance to the severity of the reaction, one should wash it off as quickly as possible. Water| HAZARD| As the temperature of water we are to use will range between 10 °c-80 °c hot water may come in contact with us and burn ones skin. | 2| If hot water comes in contact with one’s skin one must rinse thoroughly with cold water to prevent further burning. | Test Tubes| HAZARD| If one were to drop a test tube, it would be very likely for it to smash, disintegrating over the floor which could then cut someone’s foot. | 2| If there is to be a broken test tube on the floor one must alert a member of staff and sweep the area whilst restricting anyone from crossing until one has finished clearing the area. Kettle| LOW HAZARD| If one were to knock a kettle over whilst boiling water the contents would spill and henceforth burn someone or something. | 1| Keep the kett le away from electrics and other peoples working areas. | *Risk rating out of /5 Generic precautions As in all practical’s one must always take precaution of what is at hand, moreover it is obligatory to wear goggles to protect the eyes and to reduce the risk of skin contact one can wear disposable gloves.Another precaution to take is to ensure that no obstacles obstruct your movement as one may then spill a substance or break a piece of apparatus, a basic step is to push in all stools and to stand up when you do a practical. In addition a class should always leave their bags at the back of the classroom and put aside planners and books making a clear workstation. Any spills, accidents or injuries should be dealt with immediately and inform a member of staff. Review of Evidence The shape of the graph resembles that of the rate of enzyme activity graph on page 3, an arc.With the shape of the graph being similar to an arc, it displays clearly that there is a definite optimum to the rate of lipase’s activity and the stages of inactivity and denaturing. The optimum temperature of lipase on this rate graph was the same in both my preliminary data and my real results data which was 30 °c and in both instances the shapes of the graphs do resemble that of an arc. In the preliminary graph, the range bars were rather extensive for example, at 35 °c the difference between the highest (non-anomaly) result and the lowest was 0. 13 in rate.These inaccurate results could have been due to multiple factors with the more obvious being either human error or faulty equipment. By having such a difference in results it only justified the changes which we had made for the real investigation. When looking back upon my original hypothesis, it stated that before the optimum temperature the rates would gradually increase due to the lack of kinetic energy provided from the heat. Upon reviewing the graph it is clearly illustrated that there is an increase in rate from te mperatures 22 °c-30 °c with an increase of 0. 26 in rate. I also predicted that the optimum temperature would be 37 °c, due to the fact that lipase operates in the human body and the human body’s temperature should be 37 °c. By analysing the evidence of which the graph presents it tells me that the highest rate of reaction was that of 30 °c, meaning this was the optimum temperature. Finally, I predicted that once the optimum was exceeded, the rates would begin to decrease as they cannot function at such temperatures due to the breaking in the peptide bonds that holds the amino acids together.Once this bond is broken, the enzyme is reduced to its primary structure which is just peptide bonds occurring – the functional structure of the enzyme is lost and it is no longer functional; denatured. After the optimum temperature, which was 30 °c, the rate of reaction began to decline as the temperatures increased. Henceforth, my prediction was right in saying that o nce the optimum temperature had been passed; the denaturing process would begin to take place, meaning the rates of reactions would become slower.Upon looking back at my quantitative prediction, which stated that â€Å"at 45 °c will be half that of 30 °c. † However, the decrease in rate was far more drastic then I had predicted. (Rate of 30 °c was 0. 032; rate of 45 °c was 0. 005. ) This means that the process of denaturing was far quicker than I had previously predicted which in turn means that my quantitative was incorrect. However, if I were to replace the 45 °c figure in my initial quantitative prediction with 35 °c it could then be plausible as the rate of 35 °c was 0. 011 (30 °c-0. 032. )In addition, I would further modify my initial prediction bySecondary data By analysing the provided secondary data I shall be able to further prove or disprove the evidence that I had recorded. By being able to prove my data with secondary data which has the same outcom e and conclusion it proves that that the data is repeatable as there are externally recorded results that support the results that I had recorded.

In terms of the optimum temperature, it ranges from 35 °c (figure 2 ; 3) to 25 °c (figure 4. Whereas in the recorded data that I had collated, it was 30 °c with the rate for 35 °c being significantly less than half of the rate for 30 °c. When comparing the rates at 20-25 °c another difference in rate had occurred as you can see in figures 1, 2, 3 ; 4 there isn’t such a sharp increase in rates whereas in my own results there is a steep increase in rate between 22 °c and 30 °c, a difference of 0. 026. ) Moreover, in terms of the temperature at which the lipase denatures also vari ed as the denatured point in figure 3 is at 50 °c whereas the temperature at which the lipase denatured in my investigation was at 55 °c.Finally in terms of the shape of the graphs you can see that in figure 2 the shape of the graph is of a rather steady contour oppose to the sharp point that is of my graph shape. The foremost reason as to what caused such differences was the fact that the secondary investigations used an alternate for example in figures 1 ; 2 the method utilised was slightly different as they used more accurate pieces of apparatus for example they used a micropipette to measure the sodium carbonate into the test tube which would ensure for far more accurate measurements then I had made.Secondly they used a pH probe a Logger Pro to detect the change in the milk which would also prove for much more accurate readings in comparison to detecting the change with the eye as we cannot see the entire of the solution and we, henceforth, could record a shorter or longer t ime to the actual figure as we would essentially be guessing as oppose to knowing when the reaction was definitely complete. On the contrary however, they only repeated each temperature 3 times so as to collect triplicate data.In conclusion I would say that by analysing secondary data it does support my data in its general trend but in terms of individual figures, inactivity and denatured points I am unable to defend and justify that my investigation is completely reproducible. I must say that in all, I would say that the reason as to why there is a difference in the primary data and secondary data is due to multiple factors such as alternate methods, alternate apparatus and an alternate working environment.However, in total, I do feel confident in saying that my results are reproducible to such an extent that it can resemble that of the actual figures and graph shape. Evaluation of errors I believe that the changes made to the preliminary method for the real investigation did impro ve the overall accuracy of the data in the real results data. However, in the results there were many outliers that were recorded, six in total. These errors and possible inaccuracies were made possible by such factors as human error, equipment error and technique rror. In terms of human error we may have made the mistake of timing the reaction wrong because the people who are timing the investigation may time it wrong. Secondly, there may be a difference in opinion in when the reaction would have fully completed as one may say that the solution still contains traces of pink yet another may say that the solution has no traces left. Finally, there could have been the human error of inaccurately measuring the portions of the solution.In terms of equipment error, sometimes the water baths were unable to heat the solution to the specified temperature of which were trying to investigate which would then have the effect of us collating alternate data to what we should have got, this would then alter our rate bars as they be higher or lower. Furthermore, there may no longer have been a real difference in the data’s even if there was supposed to be. Secondly, our portions of the solution may have been measured inaccurately as the measuring cylinders used may have not been accurate enough for us to get precise measurements.On top of this, whilst using the pipette to measure the contents into the measuring cylinder, air bubbles were created which then alter our results as we would then be measuring a different quantity as opposed to the proposed temperature. Finally such technique errors occurred such as the lipase may have not spread equally amongst the solution which would have left a section of the solution untouched by the enzyme. Furthermore as we took the lipase out of the water bath the temperature of the lipase would either increase or decrease if above or below the room temperature.To improve the accuracies and reliabilities of the data collected and to reduce the errors as is mentioned above I would make such alterations to the existing method: -To ensure that the lipase truly got to the temperature that it was supposed to be at an improvement would be as to set the temperature of each water bath 3 °c higher than what was prepared for which would make it easier for the lipase to heat up to the specified temperature. To increase the accuracy and eliminate the of measuring incorrectly the solution ingredients an improvement could be to use a syringe as oppose to a pipette as the pipette can’t measure as accurately as a syringe because whilst using the pipette bubbles where constantly created which made it incredibly difficult to then accurately measure the contents that were to be measured in. -As is the nature of foods and drinks the milk would eventually surpass the date hat it was meant to be consumed by. However this means that the bacteria within the milk may function in a different manner because the bacteria uses the lactose sugars to reproduce, they change it from â€Å"lactose sugar† into â€Å"lactose acid,† which tastes sour and it becomes a huge food borne illness risk to consume it and it must be discarded. Instead then we can use such alternatives as UHT or powdered milk as they have longer life spans because more of the bacteria is removed. To remove the factor of misjudgement whilst trying to detect as to whether the solution has lost all traces of pink an improvement can be to use a pH probe next time as the pH probe could then accurately detect once the reaction has completely finished by seeing when the figures stop changing on the pH probe. Improved Method a. Get a test tube for each temperature being investigated. b. Add 5 drops, using a pipette, of phenolphthalein to the test tube. c. Measure out 5 cm3  of milk using a measuring cylinder and add this to the test tube. . Measure out 7 cm3  of sodium carbonate solution using another measuring cylinder and add this to the test tube. The solution should be pink. e. Place a thermometer in the test tube. f. Place the test tube in a water bath and leave until the contents reach the same temperature as the water bath. g. Remove the thermometer from the test tube and replace it with a glass rod. h. Use the 3 cm3  syringe to measure out 1 cm3  of lipase from the beaker in the water bath for the temperature you are investigating. . Add the lipase to the test tube and start the stopwatch. k. Using the pH metre wait until it displays that no pink resides in the solution. l. Stop the clock/ watch and note the time in a suitable table of results. *A control was also investigated by having a test tube with the sodium carbonate, phenolphthalein and milk but without the lipase. This is to test as to whether the solution would turn from pink to white regardless of whether the enzyme was present or not. Evaluation of proceduresWhen analysing and evaluating the procedures I shall divide the section into fo ur sectors: precision, accuracy, repeatability and reproducibility. Precision refers to how well experimental data and values agree with each other in multiple tests. [1] The only evidence to demonstrate the precision of the data is the range bars. All range bars excluding 30 °c ;0. 001, however for 30 °c the range is ;0. 001. This proves that the precision of the data was quite good with the exception of the data for 30 °c.By having a small range in data it exemplifies precision of the data as they are all within a similar region of figures. However with 30 °c the data was rather spread meaning that the results for 30 °c degrees were not precise due to the fact that my range bar is rather spread when compared to the likes of the data from 22 °c where the range bar is a quarter of the size of the range bar for 30 °c. This provides me with the necessary evidence to believe that the rest of my results were precise, with the results for 30 °c being the exception.The abi lity to obtain consistent results when measuring the same part with the same measuring instrument. [2] Upon considering the repeatability of this investigation one can say that the results are most certainly repeatable as the data resembles that of which others have collated and that of the preliminary data. If one were to repeat the investigation with the improved method then the investigation is, with no doubt, repeatable as the evidence lies within the secondary data that supports the data of which I have collated. Accuracy refers to the correctness of a single measurement.Accuracy is determined by comparing the measurement against the true or accepted value. [3] Although there is nothing we can do to improve the accuracy per say, we can, for example, remove outliers that do not share any resemblance to that of the true value, we are able to make more accurate calculations as to what the average is because we are taking out a value that does not mean anything to the true value. B y doing so in my calculations it not only improved the accuracy of the results but it also exemplified how some factors could change the results so drastically.This demonstrates that although we can control most factors that alters the results we can’t completely control them as there are endless factors as to what can affect the results recorded, for example the room temperature could affect the results is could have heated or cooled the solution. By controlling the variables of which were possible to control we did all that was possible for us to do in order of making the investigation valid. Furthermore, by repeating the outliers again to get a new set of results it would provide for a more accurate average.This is something that was not done due to the lack of time Reproducibility is one of the main principles of the scientific method, and refers to the ability of a test or experiment to be accurately reproduced, or replicated, by someone else working independently. [4] I f the results were to be reproducible then it would be possible to look at secondary data and see that it closely resembles that of the results I have provided. When comparing my results to that of peers of who are carrying at the same investigation there is most certainly a resemblance in the overall shape of the graph.Although the rates may differ the general trend of the graph does suggest the same conclusion that there is a definite optimum at around 30 °c-35 °c. http://www. slideshare. net/wkkok1957/effect-of-temperature-on-lipase-activity-using-ph-sensor -this is a link to someone else’s investigation and results (Tony Hong), from this link you are able to see Tony’s investigation and results that follow a similar method as to mine. With this it is possible to see the results and henceforth make a conclusion as to whether my results are reproducible.By looking at his data, it displays clearly that the optimum temperature that he got was 35 °c whereas in my investigation it was 30 °c. Furthermore it seems as if that his rates seem to be considerably higher than that of mine. For example, at 35 °c the rate was 0. 011 whereas Tony got 0. 00038 (s-1. ) In conclusion, it could be said that although my graph does follow the general trend of having a definite optimum and the stages of inactivity and denaturing. However, the actual figures did vary from what I had collated meaning that my investigation’s results are most probably not reproducible.Outliers As is seen in the result tables the outliers have been circled which were then excluded when calculating the averages for it could completely change the course of the results for if they were to be used as valid results whilst calculating the average it would transform what the real results were originally presenting. Such outliers occurred due to infinite factors, however there were factors of which were attempted at being controlled as is mentioned in Page 1. Overall there was a total of six recorded anomalies, this not only had the effect of creating inaccuracies but also difficulties n detecting which figure was of the figures and which were of the anomalies. Although there was the option of using a 10% lean way which would provide for a fixed bracket as to which the figures can fall into, to what would the 10% lean way be from if we didn’t know which figure was the anomaly. The only way to resolve this problem would be to repeat the anomalies in order to attain figures which support the other figures better. Conclusion In summary I believe that the investigation that I had carried out was rather successful in that it proved that there is a definite optimum temperature as to when lipase works at its best.It also illustrated the stages of inactivity and denaturing. However, the theoretical optimum should be approximately 37 °c; the optimum that was recorded was 30 °c which would suggests that there were systematic errors. If I were to repeat th e same investigation again I would most certainly make some alterations in the method so as to improve the overall validity of the investigation. Such alterations to the method would be to use more accurate apparatus such as a pH probe to detect the reaction and a micropipette so as to improve the accuracy of the measurements of the solution contents.
