Gender Roles In Primates Essay

Primate behavioral and biological research has resulted in a huge number of observations that has served as basis in understanding gender roles among their closest relatives, the humans. Earlier concepts of gender differences among primates only described that female primates influenced the organization structure of primate groups. After comprehensive analyses of primate behavior for several decades, it has now been determined that female primates serve as the foundation for primate social organization, acting as the prime individuals that shape the structure of the society, as well as mold the dynamics of primate groups (Gagneux et al. , 1999). More importantly, observations from kin selection among primates have facilitated the understanding of human sexual behavior. Primate behavioral studies have examined that the females of several primate species have diverse roles in their kin, as well as in the primate social groups. The significant increase in information associated with primate behavior has been observed in the past decade and the amount of information is massive that it has circumvented the previous knowledge on primate behavior and social roles in the past centuries. Another primate behavioral feature that has been of interest to primatologists and anthropologists is primate dominance. Earlier studies have described that male primates have an inherent characteristic of dominance, which thus can be translated to the dominant personalities among humans. However, a novel characteristic that was recently reported involved the behavior of female primates, wherein females were observed to be highly competitive among their groups, which explains the human aspect of competition among women over different issues in life. In addition, primate studies have also shown that female primates are very resourceful in finding ways in solving issues on daily living in the wild, including searching for food, a place to live and even finding worthwhile mates for offspring production (Pope, 2000). The female primates are also independent wherein they have the inherent ability of constructing contraptions and methods that would help in their survival in the wild. Such observation among female primates helps in the understanding of human females and their ability to easily adapt to different situations in life, better than their human male counterpart. Primate research has also reported that primate females are assertive in terms of sexual behavior. Primate females show the ability to control a situation when a primate male is present and they are the ones who will determine whether copulation will occur with a particular primate male. It is also interesting to know that female primates are more susceptible to promiscuity during stages of puberty than male primates. The social organization of primates is very interesting because these species also have hierarchies which determine which individual will have the right to choose his mate and this is mainly based on the level of aggressiveness of the male primate. The most aggressive male primate is thus given the first chance to pick his female primate of choice and the least aggressive male primate often ends up with lesser of a choice among the female primates. Such behavior is generally observed in human society wherein the most aggressive men often get to choose and pursue the most attractive woman and the shy and quiet men often end up with relationships with less attractive women. The female primates have also been observed to show prime responsibility over her offspring, just like the human female (Maestripieri, 1994). The primate males have also been determined to be responsible in finding food for his offspring, searching the forest for fruits and other plants that will be brought to their place of living to feed his young. The male primate has also been observed to protect their place of living from other predatory species as well as other aggressive and destructive male primates. Primate research has transformed our old concepts of human behavior and it is interesting to know that all primates follow the same behavior for specific situations.

How Cellular Phones Has Evolved Essay

Years ago cellular phones offered very limited coverage area for users. The design and function have come from big and ugly to now, tiny and flamboyant. It does not take a scientist to realize how cellular phones have evolved into a multi-function appliance. Retailers utilize technology and their creative vision to attract the cell phone consumers. The market for cell phones has increased because of social network media which is the cause for children pressuring their parents to purchase cell phones. This research will describe the most significant ways the cell phone has evolved. These ways are the camera/ camcorder, applications, and internet. Internet Lee Rannals for redOrbit.com completed a survey and the results be evidence for over half of all cell phone owners’ use their device to surf the Internet (Lee Rannals, 2012). Eighteen-percent of cell-mostly Internet users say a cell phone is more compatible with their online habits than a computer (Lee Rannals, 2012). The Internet is the most important function for the cell phone. The internet is important because any problem can be figured out. For example, if a person is out of town and direction to the nearest gas station or restaurant needs to be looked-up, they can do so by using the internet on their cell phone. They may need to look up the address, telephone number, or get directions. The internet is convenient and helps s to decipher through problems. * Jump to first hit Camera Photography often revolves around planned events, such as birthdays or weddings. Or, it relies on professional shoots. But even studiously prepared photographs must appear somehow impromptu. The images that photographers treasure most tend to be the pure opportunity shots that were captured with a combination of talent, providence, and whatever equipment was at hand. The emergence of digital point-and-shoot cameras helped to enhance photographers’ spontaneity (if not their talent). They also introduced photography to a new generation of users. The next wave of digital innovation promises to further expand this user base. It could even alter the boundaries of amateur photography. More importantly, however, the capture and sharing of images will become an intrinsic part of daily life. Applications The Applications creation has taken cell phones to greater heights. They are add-ons that carry out task other than making a phone call. Apps connect retailers to consumers. For Example, The customers for US Bank can download an application to allow them to check their bank account statement, transfer funds from one account to another, and deposit money. Also, there are games, news, sports, health, and entertainment applications. Cell phone users are able to download the applications which best fits into their desires. Carolyn Jarvis describe the application as a multi-billion dollar industry, but you can usually get an individual app for less than $2, and the options are endless (Jarvis, 2010). She said, â€Å"You have your games, your gadgets, your guides. Welcome to the world of apps. Short for application, you download it off your Smartphone. (Jarvis, 2010).† Applications are significant to how cellular phone is evolving. Conclusion Cellular phones will continue to evolve in the future because of internet, camera, and applications. They have come from being huge to small over the years. The functions have improved drastically from the keys to applications and the internet. The cell phone is compared to a smaller version of a computer based to the users. In fact, cell phone users with internet spend less time on a desktop computer. Applications allow users to connect with retailers and stay connected with friends, and capture picture moments in the past would be uncatchable. The cellular phone has evolved into a multi-function appliance and these are the reasons it will continue to evolve. References Lee Rannals. (2012, June 27). Moblie Phone Internet Use on the Rise.

The American approach to sport and physical education in the 20th Essay

The American approach to sport and physical education in the 20th Century - Essay Example Modernization theory is one perspective which explains the change and development in sports. It explains the transformation of cultural plays and games into modern sports. Thus, transformation of sports took place such that traditional games evolved into modern sports (Mechikoff and Estes 1998). The 19th century was also a turning point for women’s sports as women started participating in outdoor sports. Cycling was among the most popular sort among women and women began being seen in a wide variety of sports during the 19th century. Gender and equality factors played a great role in the development of women’s sports. As the 21st century unfolds, women sports team may become ubiquitous in every sport including extreme sports. Jim Thorpe was a great athlete who aided the development of professional as he joined professional sports teams after he lost his Olympic medals. Thorpe brought innovation to the sports he played including football and by creating unique playing strategies he developed the sports. Thorpe has lent many of his athletic tricks to the sports and can be considered as a critical sportsman to have revived the

The use of the Alternative voting system in parliamentary elections Essay

The use of the Alternative voting system in parliamentary elections would improve democracy in the united kingdom - Essay Example These reforms are sometimes evolutionary in nature and take place gradually over a long time-period; sometimes are revolutionary in nature and takes place at the spur of a moment; while at other times are deliberately brought in through changes in the legislation. UK has seen in many such reforms that have made it a modern democracy with elected representatives, from being a monarchic state (Secretary of State for Justice and Lord Chancellor, 2007, 9). My article will examine the current electoral changes that have been proposed, which signal the ushering in of the Alternative Voting system (AVs). This topic has been in debate in the UK parliament for quite some years, and is currently under review, in the House of Lords and the Parliament. My article will explore to find out whether the changes in the electoral processes that will bring in use of the Alternative Voting System or AVs in parliamentary elections, would actually work towards improving democracy in United Kingdom. Discus sion What is AV: â€Å"AV represents a very simple change to our current First-Past-the-Post (FPTP) voting system. The principle behind AV is a no-brainer: the winner in an election should need the support of a majority of the people. AV makes this happen with ‘preference voting’. ... In the present electoral process that is known as the First-Past-the–Post or FPTP, Candidate ‘A’ has garnered the maximum number of votes, and is the clearly the winner, though he hasn’t received even 50% of the total vote share, that is, majority of the voters are not backing him, yet under the present legislation, yet he must be declared the winner, thus casting aspirations on the true nature of UK democracy. However, under AV we find there are certain changes in the whole process that are certainly more democratic in nature. â€Å"With AV voters’ ‘first preferences’ are counted as before. As no candidate has 50% support the last placed candidate, ‘D’, is eliminated, and her supporters’ second preferences are transferred to the others. Still no candidate has 50% support, so candidate ‘C’ drops out and his voters’ second choices are transferred. ‘B’ emerges with majority support. She wins!†(Ibid.) Is AV more democratic in nature? A basic problem of the FPTP system that undermines the very meaning of the word democracy is that, often under this process the candidate who does not have the support of the majority of the voters, emerge as the winner. AV addresses this fundamental problem, and ensures that the winner is the person who genuinely enjoys the support of the maximum number of the voters in UK. Thus, we find we find that this system represents a more fair form of the electoral procedure, which brings forth the person who is the actual choice of the majority. The FPTPs that is in use in present day UK general elections and also used for local councils in England and Wales, is an ancient and rather outdated process, which started during the

One page - Essay Example At this point in the discussion, the representative’s tone of voice began to change from friendly and professional to impatient and irritated. The representative stated, â€Å"We are virtually the same as all other national Best Western locations†, which indicated to me that the representative had grown tired of describing the room and its features. Playing on this perceived irritation, I proceeded to ask about the different pricing for all different types of suites. I was swiftly informed that I would likely be better served by visiting the franchise website which maintained a virtual and interactive view of the room and then decide whether I wanted to make a booking online. Having not received the pricing information I had requested, the discussion ended abruptly when I agreed to visit the website. La Quinta, however, gave me a list of prices for all available room types and entertained conversation about all of the different amenities offered. This representative informed me, very politely, that there were only four rooms left and that it might be a good idea to make a final decision due to a convention occurring during my stay. Never once in the discussion did the representative of La Quinta exhibit any perceived sign of impatience, anger or unprofessionalism. Clearly, La Quinta maintained a more customer-oriented reservation system. The representative at Best Western seemed to be under the assumption that most customers were well-familiar with the Best Western brand and could not understand the depth of my questioning. La Quinta’s amenities are more pronounced than that of Best Western, offering better business traveler discounts and full-serving breakfasts unlike the more budget-conscious Best Western I had chosen. It seemed as though La Quinta understood the importance of building brand loyalty through service and had trained their representatives to be helpful, patient, and empathetic to traveler needs. The Best Western

Critical Appraisal of a Clinical Guideline Essay

Critical Appraisal of a Clinical Guideline - Essay Example It is against this backdrop that this essay is seeking to critically review and appraise the research undertaken by Chan, Lopel And Chung. Research Design The aim of the research was stated as â€Å"to investigate the perceptions of coronary heart disease among a sample of Hong Kong Chinese people.† Qualitative study was conducted using focus group interviews. To a very large extent, qualitative research has been endorsed as a very appropriate research methodology for social rather than scientific researches. Since this research was set out to find the perceptions of people about a health related issue, it could be concluded that this is a social research. To this effect, it is right the qualitative research was used. Ereaut (2011) notes that â€Å"Qualitative research seeks out the ‘why’, not the ‘how’ of its topic through the analysis of unstructured information – things like interview transcripts.† This also means that the choice of i nterview as a research design was appropriate since the research method was a qualitative research method. These two points not withstanding, in relating the research design, which was group interview to the aim of the research, it could be said that the researchers could have resorted to one-on-one interview instead of group interview. This is because the research aim focused on finding the perception of people on the coronary heart disease. In a situation like this where people’s perception are sort in a group interview, it is likely that the view, ideas and perceptions of some people would be influenced by others in the same interview group and would therefore undermine the core aim of the research, which is to find the individual perception of people. Sampling The researchers clearly stated the recruitment method or strategy used saying that â€Å"Convenience and snowball sampling methods were used† (Choi et al, 2010). They also explained how the participants were selected stating that â€Å"The LRP participants were recruited from the public domains; Participants in the MRF and MI groups were recruited from one cardiac rehabilitation and prevention centre in the community-based hospital† (Choi et al, 2010). Again, the researchers were clear on why the participants recruited were the most appropriate for the study. To this effect, they wrote that â€Å"The LRP participants had three or less CHD risk factors; The MRF participants had four or more CHD risk factors with or without a history of CHD, and the MI participants had a medical diagnosis of MI† (Choi et al, 2010). Relating the recruitment strategy to literature, Treweek et al (2010) explain that there should be sufficient participants for the research. In this direction, it can be said that the researchers were right in choosing to pick participants from as many as three different quarters. Again, Treweek et al (2010) posit that it is appropriate that â€Å"participants kn ow which treatment they are receiving in the trial, rather than having some of them receive a placebo or dummy intervention to mask this.† In this area also, it could be said that the researchers took the right step because it was clearly stated that â€Å"Each eligible participant recruited was given detailed explanation of the nature and purpose of the study. They were also informed that participation was on a voluntary basis and that they could withdraw from the study at any time.†

Folk Songs Teaching Approaches Essay Example | Topics and Well Written Essays - 500 words

Folk Songs Teaching Approaches - Essay Example This should not be the case as we have to preserve our culture and for this to be taken seriously, then, there has to be better approaches for teaching folk songs to students. There are a number of levels and methods for teaching folk songs whereby the method used coincide with the purpose of the students in learning the folk song or the purpose of the teacher in teaching the folk dance. The main aim of the teacher when it comes to teaching folk songs is to maintain quality with limited resources. Another component which is important in teaching folk songs is to understand folk song in the context; the creator of the song, which particular occasion is the song sang by the those who created it, the customs and traditions surrounding the occasion of the song, other elements of the culture that spawned it of which the song is but single element. The teacher teaches the steps, the style and the context of the folk song as he has mastered them. It is easier to teach the steps and it is difficult to teach the style while on the other hand the context has not been fully researched to be adequately learnt. However, it becomes difficult for even the best dancer to teach the styles of each different region. The teachers must admit to their students that it is difficult for one master styles of every folk songs they dance in order to encourage them.

Social Enterprise And Increasing The Overall Well-being Research Paper

Social Enterprise And Increasing The Overall Well-being - Research Paper Example From the point of view of asset management, a social enterprise can increase the overall diversification of the portfolio while at the same time add more ethical trading and investing philosophy into the overall portfolio management also. It is generally believed that portfolio managers may have to only invest in the commercial entities to generate more value for their clients. Overall risk diversification and return strategies are therefore often tailored according to the dynamics of how a for-profit business actually operates and generate more value for the portfolio managers. Non-Profit wealth creation through social enterprise is viable and sustainable activity and can increase the overall well-being of the society while at the same time allowing asset managers to actually diversify their risks and also add more ethical investing and portfolio management orientation to the whole process of asset management. (Field, 2014) This paper will be focusing on understanding the impact of non-profit wealth creation on the overall portfolio risk and return. This paper will further add on to whether the non-profit wealth creation will actually add more ethical orientation to the portfolio management or not. The overall concept and idea of a social enterprise existed for long, however, it has recently gained more momentum with large organizations such as Dannon entering into joint ventures to form social enterprises. A social enterprise’s focus is on the use of commercial strategies and tactics to achieve more value and improvement in the human and environmental well-being. A social enterprise’s main objective, therefore, is not the maximization of the shareholders’ value or wealth but to help improve the environment and the human life.

OPERATIONS MANAGEMENT Assignment Example | Topics and Well Written Essays - 3500 words

OPERATIONS MANAGEMENT - Assignment Example Summary and conclusions 18 References & Appendices Abstract The present report explores operations management at a production and service organisations with an aim to understand its main constituents and approaches; in addition, an understanding of the differences between strategic approaches of production and service operations management has been obtained. To achieve this, firstly, the report explores corporate and operations strategies as well as competitive priorities of Toyota and Accenture. Practical implications along with critical perspectives of core operational processes like capacity planning inventory management, quality, supply chain management and performance management at both organisations have been explored. Lastly, implications of these processes at operations and strategic levels have been illustrated based on competitiveness, sustainability and innovation perspectives. 1. Introduction Operations management is concerned with managing the process of creating product s and services through systematic and defined procedures. On a broader level, different functions involved in operations management of production and service industry are almost same; but the way these functions are carried are very different. In order to understand the difference, the current discourse evaluates operations management processes in two distinct organisations, i.e. the automotive manufacturer Toyota and the management and technology service provider, Accenture. Their immense success and global presence have been possible because of sustainable operations besides other activities. This report attempts to highlight the core operational activities carried out at both the organisations and how these activities have added value to their successes. In this process, competitive priorities and critical operational strategies such as capacity planning, inventory management, supply chain management, performance management, and quality approaches have been assessed. These aspect s will clarify how these organisations attained competitive position in their respective markets; and what factors have lead to their immense success despite the external and internal challenges. 1.1 Operations management: Brown (2000) describes that Operations Management involves the most critical activities of production, beginning from and including, planning and design, production processes of goods and services, and also effective integration of marketing, finance, human resources management and strategy in order to enable a business to enter and compete with both new and existing markets. In other words, a business’s success and sustainability largely depend on the operational capabilities, including efficiency and quality. These factors have been mastered by both the organisations to a large extent. Theoretically, operations management in manufacturing and service industries constitute a combination of three distinct functions, strategic functions, tactical functions a nd operational planning and control functions (Chase, 2006). Main operational processes include planning, production, purchasing or inventory management, supply chain management, distribution and marketing. Toyota and Accenture perform these processes distinctly as aligned with different competitive prior

Police in society Essay Example | Topics and Well Written Essays - 750 words

Police in society - Essay Example Dominating mentality is natural for all human beings. Police officers are getting the authority to dominate others through legal channels. If they try to use this authority simply to dictate others, such authority may yield more harm than good. So, it is necessary to make sure that the police recruits are able to use their power judiciously once they got their appointment. Psychological tests or screening are necessary to assess whether the police recruits would be able to use their power judiciously or not Courage is one of the necessary qualifications required for the police officer post. Cowards can never excel in police departments. The threats from the criminals and terrorists are attaining serious dimensions at present and the police officer should be able to counter all such attempts with courage. Only the psychological screening will reveal the abilities of a police recruit in tackling difficult situations in which courage is necessary. In short, psychological screening is ne cessary to police recruits to assess or forecast their future behavior. Vicarious liability is the liability of the superior for the acts of his subordinates. For example, an employee may feel that his manager has the authority to fire him. In fact, the employer need not given such authority to the manager. Here the employee’s belief is developed simply because of his unawareness about the organizational culture in his firm. Here the employer forced to take the vicarious liability of the acts of his manager because of the misunderstandings of the employee about his employer and manager. Chain of command is the order in which the authority and power of the top management is being exercised upon the employees at different levels. If the top management should ensure that all the employees in the organization have the right knowledge about the power, duties and responsibilities of each employees working in that firm. Otherwise employees may keep wrong inferences about the authori ty of other employees and the employer has the vicarious liability in such cases for the wrong assumptions of the employees. Harassment at workplace is common all over the world and America is also not an exception. Most of the workplace harassments are taking place because of the employee’s unawareness about his rights and the rights of his superior. The superiors often try to make the subordinate believe that he has enough power to take any actions against the employee. The employee may try to keep silence over the superior’s torture in such situations and when any disputes occur. In such cases, the employer is responsible to answer the questions about the torture, if he failed to give adequate information to the victim about the power structure in the organization well before the employees tarts his work in that organization. As per vicarious liability rule, â€Å"employers should establish anti-harassment policies and complaint procedures covering all forms of unl awful harassment† (The U.S. Equal Employment Opportunity Commission) â€Å"An injury inflicted by positive, willful, and aggressive conduct, or by design, as opposed to an injury caused by negligence or resulting from an accident† can be put under intentional tort whereas â€Å"the failure to do something that a reasonable person would do in the same circumstances, or the doing of something a reasonable pers

Portfolio Trading Strategies Essay Example for Free

Portfolio Trading Strategies Essay Profits in equity are a function of timing and costs. Trading strategies are essentially focused on maximizing profits through cost maximization which in turn is linked with transaction costs. Thus cost of trading in also a consideration for determining trading strategy. Transaction costs are said to include commissions, execution and opportunity costs. (Collins. Fabozzi : 1991). Commissions are most easy to define as these are fixed and relate to the fees paid for trading. However there is a problem of measuring execution and opportunity costs as these are neither fixed nor can be easily measured. While a number of approaches have been developed for measuring opportunity and trading costs, a method to suit all circumstances has not been evolved thus far. The complexities involved and since minor differentials make major variation in profits an effective strategy to constantly provide yield is difficult. Investment strategies thus attempt to rationalize trading to provide benefits from execution as well as opportunity costs. Since there is no uniform strategy that can assure trading profits it is very difficult to balance the large number of factors which affect trades. Timing in fact is a constant which affects both opportunity and execution costs. Opportunity Costs and execution costs are both a variable component of transaction costs. Thus profits in transaction are determined by opportunity and execution costs and the balance that will be maintained between these. Opportunity costs are the performance shortfall that arises from a failure to execute the desired trade at the desired time. These indicate the difference between actual investment and the performance of a desired investment. This is adjusted for fixed and execution costs. Thus opportunity cost is incurred for not being able to implement the desired trade. Since opportunity costs are missed investment opportunities, these could in some respects be called hypothetical costs and thus are difficult to calculate. (Collins. Fabozzi : 1991) Execution costs arise out of the demand for immediate execution and are said to reflect the demand for liquidity and the trading activity at the time and date of conducting trade. (Collins. Fabozzi: 1991). These vary with the investment style and trading demands of the investor. Both information motivated traders and information less traders could use strategies to benefit from execution costs. The information motivated trader acts in the belief that he has superior information to that available to the average dealer. Thus he executes the trade using this information for making profits. This style of trading has a large price impact. On the other hand the information less trader allocates wealth based on a price which has been factored in the trade. These have a lesser impact than information motivated traders. The problem measuring execution costs occurs as the difference in the price of the costs in absence of a trade is not observable. (Collins. Fabozzi: 1991) Execution costs are determined by market impact and market timing costs. Market impact costs are the bid/ask spread and a price concession that compensates the buyer or seller for the risk that the investor’s transaction is information motivated.   The Market timing costs arise due to the fact that at the time of execution of the trade the asset’s price moves for reasons which are not related to the transaction.   Market impact measurement is dependent on the pre trade measures, the post trade measures and also average measures which can be undertaken throughout the day. These approaches aim to define the fair value of the trade at a particular time. It is this that determines execution costs. Market making strategy thus attempts to balance opportunity and execution costs. Patient trading strategies may result in high execution costs while aggressive trading strategies could impact the other way. (Collins. Fabozzi: 1991). On the other hand the cost management methodology is designed to capture maximum elements of the transaction process. (Collins. Fabozzi: 1991). Execution costs are also shown to be higher in an automated trading process in Paris relative to the New York Stock Exchange with floor based trading with human intervention. The lower execution in floor based system suggests that there is benefit in human intervention in the trading process. This is possible as the NYSE specialist is able to maintain narrow spreads, can anticipate future order imbalances and also helps reduce the volatility of transitory movements in share prices. Thus as specialist and floor traders use the human intellect to make time preferred trades, execution costs in manual trading are considerably lower than those in automated trading. This is also supported by the role played by market makers in forming prices and providing liquidity in the securities market as per example gleaned from the trading behavior of market makers on the New York Stock Exchange.

Ascorbic acid content of fruit juice Essay Example for Free

Ascorbic acid content of fruit juice Essay OBJECTIVE To determine ascorbic acid content in a sample of fruit juice by using titration method with 0.001M 2,6-dichlorophenolindophenol, C12H7O2NCl2. INTRODUCTION image00.png Structure of Ascorbic acid Ascorbic acid, the chemical term for vitamin C, are found naturally in fruits and green vegetables. It is a dietary requirement for normal metabolism, formation of collagen, wound healing, and tissue repair. Ascorbic acid is often used as an antioxidant to help prevent free radical damage in the skin, builds resistance to infection, aids in the prevention treatment of the common cold, and aids in the absorption of iron. Yet, vitamin C cannot be synthesized by the body, and needs to be ingested. A lack of vitamin C can cause abnormalities of the spine, scurvy, and a reduction in the ability of the body to heal wounds. The determining factors as to whether organic substances can be determined in an aqueous medium depend primarily on the functional groups that characterise the redox properties. The determination of ascorbic acid content is based on the oxidation of ascorbic acid to dehydroascorbic acid: C6H8O6→ C6H6O6 + 2e- + 2H+ image01.png The redox potential depends on the pH and without adequate buffering the pH at the electrode surface can be displaced by the oxidation reaction of the ascorbic acid leading to peak broadening. Vitamin C is found in fruit drinks such as orange juice and also other sources like vegetables, liver and kidney meat. Vitamin C in food can be destroyed by cooking, leaching out from fruits and vegetable during washing, and being oxidized when expose to the air. Thus, food that rich in vitamin C needs to be stored and prepared well. PROCEDURE 1. Standardization of 0.001M 2, 6-dichlorophenolindophenol solution. 25.00mL aliquot of ascorbic acid solution was pipette into a 100mL conical flask. 0.001M 2, 6-dichlorophenolindophenol solution is titrated until a faint colour persisted for at least 15 seconds. The molarity of the dye solution is calculated by the result obtained. 2. Ascorbic acid concentration of fruit juice is determined. 5mL of fruit juice was pipette into a 100mL conical flask. 10mL of 5M acetic acid, 5mL of acetone (prevent interference of SO2) and 30mL of water was added, then the mixture was allowed to stand for 5 minutes and titrated with 2, 6-dichlorophenolindophenol solution. 3. CuSO4 and bubbling to air. 2 flasks is set up and filled with 25mL of fruit juice in each flask. 1mg of copper sulfate is added to one of the flasks and both are put to bubbled air for 20 minutes. The titration is repeated at the completion of the 20 minutes of air bubbling. DCPIP is a chemical compound used as a redox dye. This dye is blue in base (DCPIP-) and pink in acid (DCPIPH) and the pink form can be reduced by ascorbic acid to a colorless form (DCPIPH2). image03.png Titration with 0.001M 2,6- dichlorophenolindophenol solution Reaction 1: DCPIP- (blue) +H+→ DCPIPH (pink) Reaction 2: DCPIPH (pink) + Ascorbic acid → DCPIPH2 (clear) +Dehydroascorbate If a drop of blue DCPIP dye is added to a low pH solution (pH4.0), it will turn pink (Reaction 1). If a suitable electron donor such as ascorbic acid is present in that solution, it will turn colorless (Reaction 2). When all of the ascorbic acid in the solution has been oxidized to dehydroascorbate, no more electrons will be available to reduce a drop of DCPIPH to the colorless form and the solution will remain pink (Reaction 2 will not take place). The end-point was a faint pink colour that persisted for 15 seconds. (http://www.bbc.co.uk/schools/ks3bitesize/sosteacher/science/45432.shtml) Acetic acid added in Step 2 (iii) and Step 4 of the method will reduce the oxidation of the ascorbic acid by lower the pH of the orange juice to retard the action of the enzyme polyphenol oxidase. If the pH is reduced below 3.0, the polyphenol oxidase will be inactivated. Acetic acid also reduces interference from any iron present, and thereby facilitates subsequent clarification of the extract. Since the ascorbic acid is not oxidized, it was existed in L-enantiomer form. Therefore, the L-enantiomer form of ascorbic acid was determined in this experiment. ( James , 1999 ) (http://ag.udel.edu/other_websites/foodworkshop/WSFWorkshop/Enzymatic%20Browning%20(Ch2).htm) image04.png From the experiment, the molarity of the ascorbic acid and the dye solution computed are 0.001134 mol/L and 9.8425 Ãâ€"10-4 mol/L respectively. Hence, the concentration of the ascorbic acid in the fruit juice is 3.27mg/100ml which is much more lower compared to the amount stated in the product label (Sunkist) in which the ascorbic acid content is 150mg/100ml. The high discrepancy between these two values might be due to the oxidization of ascorbic acid, which was exposed to the oxygen for a period of time due to the insufficient of apparatus in the laboratory. This can be improved by not exposing ascorbic acid to oxygen, metals, light and heat, as it can be oxidized easily. Therefore, it must be stored in dark and cold and but not in a metal containment. The mechanisms of ascorbic acids degradation is commonly due to the effect of metal ions and the presence or absence of oxygen. The rate of oxidative degradation of ascorbic acids is commonly proportional to the concentration of ascorbate monoanion (HA-), molecular oxygen and the metal ion. It is known that uncatalyzed oxidation is essentially negligible but the presence of trace metals in food are responsible for most of the oxidative degradations. The potency of metal ions in catalyzing ascorbate degradation depends on the metal involved, its oxidation state, and the presence of cheletors. For example, Cu(II) is about 80 times more potent than Fe(III) while te chelate of Fe(II) and ethylenediaminetetraacetic acid (ETDA) complex is about 4 times more catalytic than free Fe(III). (Fennema , 1996) In this experiment, the potency of copper (II) sulfate in catalyzing ascorbate degradation was tested. One of the conical flask with only fruit juice act as control. It is titrated with 44.70ml of DCPIP for oxidation to occur. On the other hand, another conical flask with fruit juice and 1 mg of copper sulfate titrated with only 11.70ml of DCPIP for oxidation to occur. It is proven that the presence of metal ions responsible for accelerates the rate of degradation of ascorbic acid in an air-saturated fruit juice as less DCPIP is needed. During the step 5, bubbling through air is applied to the ascorbic acid to enhance the oxidation of ascorbic acid by the catalyst, copper. If not, it will consume a lot of time before the reaction can take place. Advantages 2,6-Dichlorophenolindophenol served as a good electron acceptor. DCPIP is used as the titrant because it only oxidises ascorbic acid and not other substances that might be present and it acts as a self-indicator in the titration It is reasonably accurate, rapid, and convenient. Can be applied to many different types of samples. Disadvantages The end point of a titration for this reaction is difficult to ascertain due to the lack of complete decolourisation of the DCPIP. These methods are not specific or are not very sensitive. The reagent itself is not stable and needs standardization before use. If the sample solution is intensely coloured (fruit juice or syrup), end point detection will be difficult. Better choice for vitamin C According to the hypothesis, content of vitamin C in fresh fruit is suppose to be higher than commercial packet fruit juice. Due to a lot of processing, most of the vitamin C in commercial fruit juice are destroy. The fewer amounts of millilitres of juice it took to turn DCPIP from blue to clear, the larger the amount of vitamin C there was in the drink. Many of the commercial fruit juice are heavily fortified with vitamin C. Conclusion The molarity of the ascorbic acid and the dye solution computed are 0.001134 mol/L and 9.8425 Ãâ€"10-4 mol/L respectively. The concentration of the ascorbic acid in the fruit juice is3.27 mg/100mL which is much more lower than the ascorbic acid content of the label product (15 mg/100mL). this might be due to the oxidation of ascorbic acid. Ascorbic acid (vitamin C) is essential to humans. It is involved in the synthesis of collagen, which is the main constituent of skin, connective tissue, and the organic substance of bones and teeth. A deficiency of vitamin C results in a disease called scurvy. A quantity of 60 mg vitamin C per day is enough to prevent the disease, and this is the recommended daily dietary allowance (RDA).

Dyscalculia Wheres The Difficulty Education Essay

Dyscalculia Wheres The Difficulty Education Essay Mathematics is a subject that is challenging for almost every learner, during all the years of education. However, there are a great number of pupils that experience this challenge, in an even worse degree. These learners have to deal with a difficulty called, dyscalculia. Dyscalculia is a specific learning difficulty, which characterises a number of people, who face severe difficulties in mathematics, and it is caused by a combination of biological, environmental and cognitive factors. The focus of this essay, will be on explaining in more detail, two specific difficulties that are related to dyscalculia. These difficulties are, the numerosity difficulties, which are basically difficulties in understanding the most basic principles of mathematics, and the difficulties with number processing and calculation, which are related to the way individuals, process the numbers, in order to make mathematical calculations and solve arithmetical tasks. A new phenomenon has drawn the attention of researchers in the area of learning difficulties, the last few years. This phenomenon is associated to the area of mathematics, and specifically, to the difficulties that learners have in the particular area. A great number of pupils have difficulties in understanding the complex concept of mathematics, something that does not necessarily mean that these difficulties are caused by a learning disability. However, there are several learners that have an extreme difficulty in Mathematics (Reid, 2003, p. 252), a difficulty that is related to a specific type of learning difficulties, which is called dyscalculia. Dyscalculia can be defined as a condition that affects the ability to acquire arithmetical skills. Dyscalculic learners may have difficulty understanding simple number concepts, lack an intuitive grasp of numbers, and have problems learning number facts and procedures. Even if they produce a correct answer or use a correct method, they may do so mechanically and without confidence (DfES, 2001). In other words, learners, that are dyscalculic, may have difficulties, not only in the procedures that are important in solving a maths problem, but also they may have difficulties in understanding the basic notions of mathematics, such as what does the magnitude of a number represents or what the maths symbols signify. Therefore, the difficulties that dyscalculic learners face, in the area of mathematics, can be rightly considered as more severe than the difficulties that pupils, who dont have a specific learning difficulty, face in maths. Regarding the causes of dyscalculia, there seems to be a variety of biological, environmental and cognitive factors that lead to this learning difficulty. In particular, a study by Shalev et al. (2001) revealed, that children, who have siblings with dyscalculia, are at a very high risk of becoming dyscalculic, in comparison with the general population. This study supports the idea that was firstly introduced by Kosc (1974), which proposes that dyscalculia is related to genetic factors. This idea is also supported, by a research with monozygotic and dizygotic twins, which revealed a percentage of 58% and 39% respectively, between the siblings, in the emergence of dyscalculia (Alarcon et al., 1997). In addition to this, there also seem to be some differences between dyscalculic individuals and individuals who dont have a difficulty in maths, in the way their brain functions, during mathematical procedures (Shalev and Gross Tsur, 2001). According to several researchers (Levin et al., 1996; Levy, Levy Reis and Grafman, 1999), who studied the brain activity of two dyscalculic adults during arithmetic processing (Shalev and Gross Tsur, 2001, p. 339), there seems to be a unilateral activation of the frontal and parietal areas of the left hemisphere of the brain and also a deficiency in the parietotemporal region of the specific brain hemisphere, in dyscalculic individuals. On the contrary, individuals, who dont have a specific learning difficulty, during mathematical procedures, have a bilateral activity on their prefrontal and inferior parietal cortices (Rueckert et al., 1996 in Shalev and Gross Tsur, 2001, p. 339) rather than a unilateral activation. One cannot be sure though ho w accurate is this fact about dyscalculic individuals, because the studies, that took place in order to examine the brain differences of dyscalculic individuals in comparison with the general population, had a sample of only two people with dyscalculia, who were adults. This small sample may not be very representative of the dyscalculic population in general, and therefore the suggestion that there are differences in the brain activity of dyscalculic individuals, in comparison with individuals without maths difficulties, during mathematical procedures, may not be factual and may need further examination. Furthermore, there are several researchers, who dont believe that dyscalculia, is a learning difficulty that has a biological basis. They consider a number of environmental factors to be more accurate in explaining the nature of dyscalculia (Shalev and Gross Tsur, 2001). Specifically, they believe that factors, like not having the opportunity for a proper education (Miller and Mercer, 1997; Gifford, 2005) or not being confident about your mathematical skills (Gifford, 2005), is the reason why several learners have dyscalculia. However, one cannot be absolutely sure that the difficulties, an individual has in maths, because of these factors, could truly cause dyscalculia or if they just characterise an average person, who has several difficulties in maths which can be reduced by improving these factors. Maybe further research, which will examine if dyscalculia stays persistent even after improving these factors, could solve this reflection. Another environmental factor, which may lead to dyscalculia, is the anxiety that is generated to the learner, because of maths (Ashcraft, 1995). According to Ashcraft (1995), maths anxiety can cause dyscalculia, because learners with this type of anxiety tend to feel really nervous when they have to deal with maths, something that makes them to do mathematical calculations really quickly. Therefore, the learners, because of their hastiness in making mathematic tasks, they may have low performance and inaccurate results in mathematics, something that could be considered as dyscalculia or it could make the situation for a dyscalculic learner even worse (Ashcraft, 1995). Also, maths anxiety could lead to low self confidence. Still, it is more possible that maths anxiety worsens and not causes dyscalculia or math difficulties in general, because if dyscalculic learners are forced to make arithmetical procedures hastily, then they probably will make more mistakes or they wont be able to solve a maths problem at all, because of the pressure they might feel. Furthermore, maths anxiety is something that all students and not only dyscalculic students may experience at some point, as a result of the complex nature of mathematics, and therefore its causal role for dyscalculia is questionable. Overall, one may assume that maths anxiety is not necessarily a causal factor for dyscalculia, but it is a characteristic that a dyscalculic learner could present. Regarding the cognitive factors that are responsible for dyscalculia, there seems to be a belief that a dysfunction on the visuospatial abilities or the verbal and auditory comprehension abilities, of an individual, can cause dyscalculia, as well as other cognitive disabilities (Rourke, 1993). In addition, several other researchers (Geary, 1993; Koontz and Berch, 1996) believe that problems with the working memory, can also lead to dyscalculia, because it affects the effort of learners in performing mathematical procedures. According to a research by Temple and Sherwood (2002) though, children with dyscalculia didnt have any differences in comparison with children without dyscalculia, in any of the tasks that measured their working memory, and also a correlation between the working memory and the arithmetic ability measures, was not found. Therefore, it is not certain if working memory difficulties have a causal role in dyscalculia or if they appear at the same time with the difficul ties that are linked to dyscalculia (Butterworth, 2005). Overall, a combination of all the factors, that are considered to play a causal role in the development of dyscalculia, may clarify in a better way the concept of dyscalculia. This is because, dyscalculia seems to be a disability that is more possible to be generated by a great number of factors, just like dyslexia (Frith, 1997), rather than by only one, and therefore, it could be better understood if it was seen as whole. That is, to be seen from all the aspects that could generate it, rather than from one aspect only. A better understanding of dyscalculia may also arise by examining the difficulties that are linked to it, and not only be examining the causes of it. Specifically, there appear to be several difficulties that can be identified on dyscalculic learners, difficulties, which in a way, are connected with each other. These difficulties have to do, with the way learners comprehend mathematics from their simplest form to their most complicated one. In particular, they have difficulties with understanding arithmetical concepts, like the numerosity of a number that refers to understanding the magnitude of a number, with the processing of mathematical facts and the calculation of them, which refers to how a learner processes the numbers and the maths symbols that he sees in order to solve a task, and also with difficulties that may be associated with other learning difficulties, such as dyslexia and ADHD, because of the high co morbidity there is between dyscalculia and these two learning difficulties (Shalev and Gross Tsur, 2001; von Aster and Shalev, 2007). For example, in the case of co existence of dyscalculia and dyslexia, the learner has maths difficulties that are related to language, such as reading mathematical problems and solving maths exercises following the correct sequence (Reid, 2003; Bennett, 2006). In the case of dyscalculia and ADHD, a possible difficulty that a learner may have, is not being able to finish a maths task, because of the lack of concentration he may present, something that usually characterises learners with ADHD. This difficulty may also be present to dyslexic learners as well, because of the high co morbidity there is between dyslexia and ADHD, and therefore a learner may have dyscalculia, dyslexia and ADHD concurrently (von Aster and Shalev, 2007). From this, one can assume that there are four categories of dyscalculic learners; learners with dyscalculia alone, learners with dyscalculia and dyslexia, learners with dyscalculia and ADHD, and learners with dyscalculia, dyslexia and ADHD. Even though the issue of the difficulties that a learner may present, because of the co morbidity between dyscalculia and these two other specific learning difficulties, seems to be really exciting and interesting, this essay will focus on the difficulties that characterise learners with dyscalculia alone. Specifically, it will focus on the difficulties that dyscalculic learners have with numerosity, number processing and calculation of mathematical procedures, rather than on the difficulties that result from this co morbidity. In particular, the first difficulty mentioned above, which is numerosity, refers to the abstract form of numbers, which reveals their magnitude (Butterworth, 2005), and it should be the first thing that learners should learn, in order to be able to understand mathematics. As Butterworth (2005, p. 3) indicated, numerosity can be the basis of arithmetic. The numerosity refers to an abstract type of numbers, because it is possible for numbers to be arranged in different sets that can be represented by different parts, which may have abstract or concrete substance, like straws, sticks, sounds etc. (Butterworth, 2005, p. 3). In addition, when several parts are being put in a specific set to form a number, something that represents the numerosity of this set, the learners can easily understand them, in comparison when they see these parts (e.g. dots on dice) in a different order (Mandler and Shebo, 1982). Therefore, numerosity is significant in learning and understanding the numbers, and w hat these numbers represent, especially when it is presented in specific groups. According to Butterworth (1999), there are four principles that a learner should follow in order to comprehend what numerosity is. Firstly, he must know the one to one correspondence principle (Butterworth, 1999 in Butterworth, 2005, p. 4), which refers to the ability of a learner to recognise when the numerosity of two sets of numbers is the same, by examining the parts of each set which must correspond to each other (Butterworth, 2005). In other words, in order for two sets to have the same numerosity, they must be constituted by exactly the same number of parts. Secondly, it is important for the learner to understand that numerosity is a variable and not a fixed concept and that different sets may have different or the same numerosity. Thirdly, the learner must have in mind that numerosity can be abstract, and therefore the sets may be represented not only by concrete things but by invisible, abstract things (Butterworth, 1999 in Butterworth, 2005, p. 4) as well. Finally, it is i mportant for a learner to be able to identify numerosities of sets of four objects the most, without needing to count them verbally. One can suppose that these principles are truly essential in order for a learner to be able to understand the complex meaning of numerosity, because in fact, these principles compose the concept of numerosity. Therefore, by being able to comprehend these aspects, a learner will be able to understand numerosity as well. Regarding the abilities that a learner must have, in order to have an appropriate understanding of numerosity, Piaget (1952) talked about three basic abilities. The ability to reason transitively, the ability to understand the stability of the number of items in a set, and the ability to recognise the abstract nature of the items that form a set despite their personal characteristics, like their colour or shape (Piaget, 1952 in Butterworth, 2005, p. 4). Specifically, the first ability refers to logical calculations that a learner can make, after examining several facts. For example, if there are three items, from which the two have the same size and the third is smaller, then the learner must be in position to identify that the third item will be smaller not only from the first item, but from the second item as well. The second skill that should characterise a learner, in order to possess the idea of numerosity, is to know that the number of items in a set will not change if there is a modification in their sequence, except if an item is removed or added to the set. The third ability, is relevant to the suggestion made by Butterworth (2005) regarding the abstract character of numerosity and also the one to one correspondence principle, because it has to do with the fact that the characteristics of the items of a set cannot affect its numerosity, and therefore it is possible, two sets that are structured by different items, to have the same numerosity. The principles, mentioned by Butterworth (2005), and the abilities, mentioned by Piaget (1952), about the comprehension of the concept of numerosity, may be affected in dyscalculic children, because these children have already problems in understanding the general idea of numerosity (Butterworth, 2005). Specifically, children with dyscalculia seem to have difficulties in comparing the magnitudes of several numbers (Geary, Hamson and Hoard, 2000) and also in counting tasks (Koontz and Berch, 1996), something that could lead to the conclusion, that these children have numerosity difficulties, as numerosity is the basis of this type of abilities. Regarding the counting skill, in order for a child to be able to count, he must firstly know the counting words, then he must connect each counting word with only one object, and finally he must have the awareness that, the last counting word he says, is the total number of all the things in a group that he counted, something that basically is the numerosity of the group (Butterworth, 2005). These three characteristics represent the three principles, which were suggested by Gelman and Gallistel (1978) to be essential for the ability to count, and they are called, the stable order principle, the one to one principle and the cardinal principle, respectively (Gelman and Gallistel, 1978 in Butterworth, 2005, p. 7). Two other principles were indicated by Gelman and Gallistel (1978 in Butterworth, 2005, p. 7) as well, which are the abstractness and the order irrelevance, and refer to the ability to recognise the abstract nature of numbers, something which was noticed by Piaget (1952) as well, and the awareness that the order, in which a learner starts to count the items in a group, is not important, as long as he counts each item only once. The principles indicated by Gelman and Gallistel (1978), depend on the principles of numerosity and therefore, in order for a learner to encompass these principles, he must first encompass the idea of numerosity (Butterworth, 2005) A dyscalculic learner may have difficulties with counting, because as it was noticed by Geary (1993) and Koontz and Berch (1996), dyscalculic children may have several difficulties with their working memory, and therefore they will find it difficult to count a large amount of objects. This is because, they probably wont be able to maintain in their memory the number of the items that they have already counted, in order to count the rest of them and therefore to find the total number of the items. This difficulty seems to be associated with the third principle, which was indicated by Gelman and Gallistel (1978), because if a learner is not able to remember the items that he counted until one point, he may then consider as the last number of a set, which will represent the total of the items as well, an incorrect number. In addition, sequential and visuospatial difficulties (Bennett, 2006; Rourke, 1993), that usually characterise dyscalculic learners, may also affect a dyscalculic lear ners skill to count, because he may find it difficult to count an item only once, following the one to one principle (Gelman and Gallistel, 1978 in Butterworth, 2005, p. 7), because of the confusion he may have about the sequence of the items. Therefore, one can assume that this kind of difficulties, affect not only the ability of a dyscalculic learner to count, but his knowledge about numerosities as well, as numerosity is essential for counting. These particular difficulties, can lead to the appearance of other maths difficulties as well. These difficulties have to do with the number processing and calculation abilities. According to McCloskey, Caramazza and Basili (1985, p. 173), the number processing skills, have to do with the ability of a learner to understand and produce numbers, and the calculation skills, refer to the facts and procedures that are necessary in making mathematical calculations. In particular, McCloskey et al. (1985, p. 173) referred to two different systems that are related to these skills, which are the number processing system and the calculation system. The number processing system, is composed by two subsystems, the number comprehension subsystem, and the number production subsystem (McCloskey et al., 1985, p. 174). These subsystems include two units, the Arabic numbers unit and the verbal numbers unit, which have to do with the appearance in which the numbers are presented, either in digit or in oral / written form correspondingly. Each of these units is divided into a lexical processing and a syntactic processing element (McCloskey et al., 1985, p. 173). These two elements are associated to the ability, to recognise each part of a number (lexical processing) and to the ability to recognise, according to its elements, the specific number (syntactic processing). For example, if the number 516 is presented to a learner, either in Arabic or verbal form, he must be able to recognise the meaning of each number of the set, something that has to do with the lexical element, and to understand that, with this order, the specific numbe r, will have five hundreds, one tens and six units, a procedure that depends on the syntactic element (McCloskey et al., 1985). Dyscalculic learners may present difficulties on one of the subsystems of the number processing system and consequently, on one of the units or the elements that these two subsystems include. Specifically, a research by Benson and Denckla (1969) with one dyscalculic individual, revealed a difficulty in the production of numbers of both forms and in the lexical processing of numbers, whereas the individuals comprehension and syntactic processing components, were fine. In addition, McCloskey et al. (1985) noticed in two dyscalculic individuals, that one of them had difficulties in distinguishing the magnitude of two numbers when those numbers were presented verbally, and the other individual had difficulties when the numbers were presented digitally. Even though the difficulties indicated by Benson and Denckla (1969) and McCloskey et al. (1985) are difficulties that a person could notice in dyscalculic learners, one cannot be sure about the reliability of the results of the specific studies, because the sample they used was really small and because the studies took place several years ago, and consequently the particular results, may not be adequate for today. However, some of these difficulties, like in the case were the individual had to compare two numbers about their magnitude, seem to be associated to the concept of numerosity mentioned above, and therefore these difficulties, may be sufficient in characterising dyscalculic learners. Regarding the calculation system that was indicated by McCloskey et al. (1985), it is constituted by three units and it depends in some point on the number processing system. These three units, work independently from each other, and have to do, with the way the maths symbols, or words, are processed, with the arithmetic facts, and with the calculation procedures (McCloskey et al., 1985, p. 179). The first unit refers to the ability of a person to understand what calculation he must do, in relation to the maths symbol or word that is presented to him (McCloskey et al., 1985). For example, when a person sees the symbol x or hears the word multiply, he knows that the operation he must do, is multiplication. However, a dyscalculic learner may confuse the arithmetic symbols and, even though he may know the right answer, he may answer incorrectly. Something similar happens when the arithmetic symbols are presented with words, but with the difference that when maths problems are related to language, there is a belief by several researchers (Reid, 2003; Bennett, 2006) that these problems are more associated to maths dyslexia rather than to dyscalculia, and therefore this suggestion is more related to the co existence of dyscalculia and dyslexia, rather than to dyscalculia itself. Overall, difficulties with the arithmetic symbols or words may be generated by visuospatial (Rourke, 19 93) or language difficulties (Reid, 2003; Bennett, 2006) that sometimes characterise dyscalculic learners, thus dyscalculia can be characterised by difficulties with the operational symbols as well. The second unit is related to the ability of an individual to maintain and retrieve from his long term memory, the correct answers of specific mathematical facts (McCloskey et al., 1985). An example of arithmetic facts, is the knowledge of a learner about the times tables. This unit is independent from the first one, because a learner may have difficulties in recognising the operational symbol, but his answer may be correct when another symbol is used, or he may do the right operation but retrieve the incorrect arithmetical fact. For example, Ferro and Botelho (1980), noticed in a dyscalculic learner, that instead of adding two numbers when she saw the symbol +, like for example 9 + 2, she multiplied them and answered 18 instead of 11. In addition, McCloskey et al. (1985) observed that a dyscalculic individual couldnt retrieve the correct answer in a case of multiplication, even though he understood the concept of multiplication adequately. Several dyscalculic learners may face diff iculties in learning or in retrieving arithmetical facts (Russell and Ginsburg, 1984; Kirby and Becker, 1988; Geary, 1993; Temple, 1994; Ginsburg, 1997; Jordan and Montani, 1997; Geary and Hoard, 2001; Shalev and Gross Tsur, 2001), and a reason for this may be the fact, that some dyscalculic individuals have difficulties with their working memory (Geary, 1993) or with their long term memory, as well (Reid, 2003). This, may limit the ability of a learner to maintain or to retrieve a mathematical fact from his long term memory, and therefore to cause him difficulties that characterise dyscalculia. The third unit of the calculation system refers to the abilities that learners have in making mathematical calculations (McCloskey et al., 1985). These abilities are related to the way learners comprehend and learn the procedures of executing math calculations, something that in dyscalculic learners is usually impaired (McCloskey et al., 1985; Temple, 1994; Butterworth, 2005). For example, dyscalculics may have difficulties in completing procedures in which they have to carry a number, whilst doing a maths operation, because of the fact that they may put the number on the wrong place, something that leads to wrong calculations. Also, they may have difficulties with procedures, in which they must do two different mathematical operations at the same time. Both of these difficulties, may be the result of sequential difficulties (Bennett, 2006), or again of memory difficulties (Geary, 1993; Reid, 2003), that are considered to be related to dyscalculia, and therefore dyscalculics may face this kind of difficulties, as well. The specific model for number processing and calculation abilities, even though it was created several years ago, is in general lines, sufficient in explaining this type of abilities, in relation to dyscalculia. In addition, the aspects described in the model, seem to be have a common ground with the numerosity, described above, regarding the causes of the difficulties that dyscalculics may present. Therefore, one can assume that similar methods can be used, in order to help a dyscalculic learner to limit his difficulties with numerosity and with number processing and calculation abilities. Specifically, several researchers suggest that multi sensory methods (Bennett, 2006) in combination with the learners learning styles (Chinn, 2001; Marolda and Davidson, 2000; Sharma, 1989) can be vital in teaching and helping dyscalculic learners. This is because, by focusing on the way that an individual learns the best, one can help this individual to grasp the concepts of numerosity and of nu mber processing and calculation, in the greatest extent, and by using multi sensory methods, he will make the learning for the individual to be fun, less stressing and more motivating. With this way, the learner will probably feel more confident, and therefore more determined to improve his difficulties in mathematics. In conclusion, dyscalculia is a very recent issue in the area of learning difficulties, and

What Is Organization? Essay -- Management

To organize means to determine what activities are necessary for a specific purpose and to encourage them in groups, which are assigned to individuals. An organisation is a complex social system, which brings together many individuals for a given purpose. It is also an arrangement of personnel to facilitate the accomplishment of a given purpose through the allocation of functions and responsibilities. To further understand the definition of organisation let us consider the definition developed by Max Weber. Like any other field of study, and like organisation themselves, organizational analysis has a tradition. That tradition leans heavily on Max Weber, who is known for his analysis of bureaucracy and authority, topics that will be considered later. Weber also concerned himself with the more general definitions of organisation. In his definition he first distinguishes the "corporate group" from other forms of social organisation (Weber, 1947). The corporate group involves "a social relationship with either closed or limits the admission of outsiders by rules... so far as its order is enforced by the action of specific individuals whose regular function this is, of a chief or `head' and usually also a administrative staff." This aspect of the definition contains a number of elements that need further discussion, since they are basic to most other such definition. In the first place, organisation involves social relationship. That is, individuals interact within the organization. However as the reference to closed or limited boundaries suggests, these individual are not simply in random contact. The organisation (corporate group) includes some parts of the population and exc... ...inciples, developing models of organisation that were overly rational and mechanistic. The Type 2 theorist, to a large degree, represented a counterpoint to the rational-mechanistic view. The current stage of organisation theory more fully reflects the contribution of the type 3. Contingency advocates have taken the insights provided by the earlier theorists and reframed them in a situational context. Nevertheless, we should not conclude that the findings of the earlier management thinkers would be useless in the future. For, example many of the concepts developed by early classical writers are still of value today; the study of the management task in terms of functions performed and the use of management principle as guides to actions are still very much with us and are expected to remain valuable. Few who manage will be able to escape at least some of their impact.

The Color Purple by Alice Walker Essay -- essays papers

The Color Purple by Alice Walker The Color Purple by Alice Walker is the story of a poor black woman living in the south between World War 1 and World War 2. This was at a time when, although slavery had ended,many women were still virtually in bondage, and had to put up with many conditions that was reminiscent of the days of slavery. The problem was that they had to endure being treated like an inferior being by their own families sometimes, as well as from the white people that lived there. It was a life that was filled with misery for many black women, and they felt helpless to do anything about their situations. The book focuses mainly on a woman named Celie, who has lived a hard life already when, at the age of 14 she begins writing letters to God to have someone to confide in,and tell her thoughts and secrets to. In her first letter, she says â€Å"I have always been a good girl. Maybe you can give me a sign letting me know what is happening to me.† (1) Already at that age she has been taking care of her brothers and sister, and has been working very hard at trying to get something of an education. On top of this, she has been raped by her father repeatedly because, as he says, â€Å"You gonna do what your mammy wouldn’t.† (1) She has had two babies by him already, and he’s taken both of them away right after they were born. She thinks at first he might have killed one of them, but later finds out that he sold them to a couple in town. Celie doesn’t do anything about her situation, because she’s used to being treated like that. She’s scared, and she fears for her sister Nettie too, when her Pa starts looking at her the same way. Eventually, a man referred to as Mr. ______ comes along and wants to marry Nettie, but he’s too old for her, and ends up marrying Celie. He takes a couple of months to think it over, but goes ahead and marries her because he needs someone to watch over his kids, and besides, she will bring the cow she was raising along. It’s not so much he wants a relationship, he just wants someone to take care of things for him so he doesn’t have to do much, and he wants something else when he wants it. Her father even tells Mr. ____ that â₠¬Å"She ugly... But she ain’t no stranger to hard work. And she clean. And God fixed her. You can do everything just like you want to and she ain’t gonna make you feed it or clothe it.† (9) As soon ... ...inds that she can be happy and content having her own life, without being treated like a doormat by others. She is finally truly happy with her life and the way it is going, except for one thing. Her life is complete when, after years of wondering about her sister, and then years of waiting, Nettie finally comes home, bringing â€Å"their† children, and Adam’s wife from Africa. As Celie puts it, â€Å"I feel a little peculiar around the children. For one thing, they grown. And I see they think me and Nettie and Shug and Albert and Samuel and Harpo and Sophia and Jack and Odessa real old and don’t know much what going on. But I don’t think us feel old at all. And us so happy. Matter of fact, I think this the youngest us ever felt.†(295) With her long lost sister, and her kids reunited with her after so much time, there really wouldn’t be any other way to feel besides young again, except for maybe an urge to make up for lost time. Now that she’s being treated like she should be, it should be easier to make up the time to her family, because she can be herself, and be happy about it. That’s saying a lot after all she’s been through, and Celie will surely make the best of her from this point on.

The Affordable Care Acts Long Road to Political Reality Essay

The Patient Protection and Affordable Care Act is the first health-care reform to pass Congress that will attempt to provide health insurance to all American citizens. It is not the first time that a health-care reform of this magnitude has been attempted. Previous attempts at health-care reform were not successful. The passage of the Patient Protection and Affordable Care Act was certain only at the 11th hour after much discussion and compromise between different factions within the government and private sector. President Clinton had argued during his 1992 presidential campaign that health-care reform was needed. At the time, 37 million Americans were without health insurance. He also pointed to the fact that the United States was the only modernized democracy that did not provide universal health-care coverage for its citizens. On September 22, 1993, President Clinton gave his kick-off speech to Congress on his proposed health-care reform. The reform included a mandate for employers to provide health insurance to all employees. These insurance plans would be offered through a regulated marketplace. The proposed reform was considered a great success by Democrats in Congress and in public opinion polls. However, by spring 1994 the proposed reform has been labeled as â€Å"too large, too complex, too costly, and too much government (Pfiffner).† Public opinion, which was fundamental to this legislation, had begun to shift. Although there was public consensus that the United States health-care system needed to be overhauled, there was no consensus on what needed to be done to fix it. The reform, ultimately, did not pass in Congress. Several factors were pointed to as causes for its failure. Along with the complexity... ...

Kudler Fine Foods Frequent Buyer Program Essay

The intent behind the development of Kudler Fine Foods Frequent Buyer Program is to increase the level of customer loyalty. The system will be broken down into two different levels; the frequency of a buyers shopping with Kudler Fine Foods and the amount of money that the buyer spends with each purchase. A program like this is typically used as a marketing strategy that is â€Å"enabled by point-of-sale technology to record and store customer purchases in exchange for rewards’ (Appel, p. 156, 2006). A web-based shopping program will be used to enhance the Frequent Buyer Program for Kudler Fine Foods. This will be achieved by applying web-based advertising. A projection of frequent buyers growth is expected on the initial employment of the frequent buyer program. It is the estimate of the Sales and Marketing Department that there will be a 5% growth within the first 12 months of this program. The department has also conducted an analysis considering what legal courses of actions, if any, Kudler Fine Foods will need to take to ensure the success of this program. Legal Considerations A study of the consumer trends in this area will have to be conducted. The will enable the Sales and Marketing Department to allow for a smooth and functional program and give them an idea on how to better market the product. â€Å"Market research and demographics data can be used to better target products and produce better or customized products; such data are becoming increasingly valuable: (national Research Council, p. 156, 1994). Some of the legal issues that will be taken in to consideration are costumer privacy as this will have an increased attention in response to the initial data that we will be requesting. It is important that Kudler Fine Foods incorporate some sort of privacy statement into the initial request form stating that the information will not be shared with anyone outside of Kudler Fine Foods, and state the basic reason of why Kudler Fine Foods is requesting such data. Employees of Kudler Fine Foods will need to be trained on the proper handling of such data and what ramifications can happen in the event that costumer information is released without the expressed consent of the costumer. Ethical Considerations The intent of the Frequent Buyers Programs with Kudler Fine Foods is to be one of electronic commerce application. An e-commerce program can provide Kudler Fine Foods another level of costumer shopping and potentially receiving new customers for Kudler’s. As the program grows so will be profit margins of the company. However, internet security will have to be in the foremost thought of the IT Department in the development stages through the employment of the Frequent Buyers Program launch. The IT systems employed will â€Å"gather personal data about customer bases, and use it to support vital functions, such as the authentication of individuals requesting service, verification of credit and accounting information, delivery of services and goods, marketing, decision-making and law enforcement† (Appel, p. 156, 2006). Security Considerations The design and development of the database should not solely be focused on the access to and the protection of the personnel identifiable information that is being stored of the database. This information should be considered sensitive as it could be access in the attempt of identification theft or other forms of fraud. Programs of the nature have shown that they release they sensitive information to third party buyers. (Appel, 2006). Purchases that an individual makes should be held in a private and secure location and should not be shared with anyone outside of Kudler Fine Foods. An implementation of this should help ease a buyers concern that we are sharing their information with anyone who does not need to have it. The development of Kudler’s e-commerce site should be designed to fully secure. This is to help any unethical occurrences form happening; however, it will not prevent them from being attempted. Financial Analysis This initial cost of the startup of this program will be a minimal impact on Kudler Fine Foods. The initial advertisement effort will be done via social media; the companies Facebook page and Twitter account, email and word of mouth. Allowing for a reward system for costumer referrals can be used for current and new customers as the programs is employed and continues to grow. Rajiv and bell argue â€Å"customer retention costs are generally lower than customer acquisition costs, companies are better of focusing attention on their more loyal customers especially since the top 20% of customers account for 80% of revenues and often more than 100% of profits† (p. 180, 2003). Kudler Foods could reduce their marketing expenses by using a customer loyalty system through the use of rewards. The sales increase from this program should be reflected by the increase of new customers and the increased returning customers increased spending. The use of seasonal promotions only available to costumers enrolled into the frequent buyers program could also help in increased sales profits. Conclusion A frequent shopper program can be a successful tool is used correctly by a company. The difficult task will always be bringing in new costumers. This program should allow for the retention of existing customers with Kudler Fine Foods. A rewards points system should be used for the exchange of costume items only available to customers enrolled in the frequent shopper program. This will entice customers to remain loyal to the company and refer the friends and family to the program. The increased awareness of the customers privacy should always stressed from the designing of the program, through the implementation and further in the continuing changes of the program. Ensuring that the customers understand that their information is not shared with any third party organizations and that their information will help in the advancement of this program should minimize conflicts. The paramount concern should always be information security and privacy of customers identifying information will help keep this program a success.
