Business Ethics - Term Paper Example Business Ethics The other pressure that is involved is the fact that Doug had stated that the last person who had tried to raise the issue was sacked because of asking about the issue. That means that the job may be at risk and it could be lost if the management is not accommodative enough. In this situation, the questions that I would ask myself include the following, if there is an ethical issue at hand. The ethical issue that is under consideration is the fact that the bikes will not be effective and that may lead to loss of lives and other bad outcomes. The other thing I would do is to establish the key principles and values that are involved in the issue. The issues that are involved include the fact that the bike will be ineffective after 4 hours of usage. That can be checked to ensure that is a fact. The other thing would be to rank ethical principles that are relevant in the dilemma. The issues that can be ranked include the company’s profitability against the value of people’s lives. The other step would be to prepare an action plan that should be in line with the ethical principles. The action plan will be to suggest that the bikes be improved or totally scrapped off to ensure the safety of the users. After that, I would implement my plan laid down. I would not recommend that the company pays the special $5,000 for the pedal to be placed on shelves of shops. That is not legal and ethical. Every product should be placed on shelves at the will of the buyer but the shop owners should not demand a price for putting the products on the shelves. That may be viewed, as a bribe and it would not be ethical. The considerations that can be put in place are the reasons that are behind the payment of the special fee. Green Move Company should not apply the cost/benefit analysis on the safety of the product. The costs may be more adverse and also the life of a person is not something to gamble with and it should be the first consideration while the rest come last. The risks that are involved include the company being sued for more money in case there is a loss that occurs and it becomes associated with the manufacture of the zero pedals. The other risk is the fact that the company may lose its reputation and that will be a risk factor because that will imply that the products that the company will sell in the future may not be considered by the customers. Question B Every organization should be a different entity from the affiliate companies and the owners. The owner of a company cannot be judged because of something that may have happened in his or her company. That also applies to the companies that are associated with a supply chain. A supply chain will involve wholesalers and retailers. All the businesses that are found in the supply chain are independent not unless they are owned by the same company. That means that each company transacts its businesses independent of any other business. In the case of the agreement between Green move and solar group, the agreement is not legally binding. The agreement is one that interferes with the internal affairs of another company and that means that the independence of the other company is interfered with. Anything that happens in another company can not affect

World Wide Web and Internet Essay The Internet is certainly the place for businesses to expand, reach new markets and provide new services but there must be a balanced approach to the Internet. The Internet must be regarded as a strategic resource important to the whole business. The technical detail of the Internet can be complex. Management responsibility however is more productively focused on managing the implementation process to achieve strategic goals and assure smooth, secure operations.

In deed internet addiction can be called â€Å"a mental illness†.Playing online games reasonably can make people happy on free time.

Sign Language Policy And Planning Education Essay

Sign Language Policy And Planning Education Essay To promote the students who get knowledgeable about the sociolinguistic circumstance of minority sign language, the strategies from maintenance and merchandising the same sign language. To help the students who gain awareness of the nature and process of language change and the various theories towards development and practical utilization in endeavour language change that the maintenance and urge sign language on. To provide the students who are the significant analyse experts that desire to be fascinated by sign language planning and policy which contains data collection, analysis and presentation. To deepen the students understanding who utilize the knowledge of the legislation and policy system from sign language planning in international that do letter with reference to some particular counties and international progression. A case study is probable to provide the different interpretation which method of sign bilingualism from variety national and progress understanding of key policies. For example sign bilingual, sign language recognises two signs in ASL and ISL for sign bilingual. A case study demonstrates the theories related to language planning and language policy which is meaningful. To analyse the theoretical debate emission related to language planning and policy. The policies are different compared to urge on sign language that policies in bilingual. The analysis difference that can influence language utilization and language attitudes in social. Indicate the talent to analyse theoretical methods which influence minority of sign language planning and policy. I understand about this topic by Linguistic Policies, Linguistic Planning, and Brazilian Sign Language in Brazil and Language Policy and Planning: I have read the case study of The Case of Italian Sign Language. The reason I chose the topic is because am fascinated to know more about language planning and policy, the difference the deaf association contact other deaf people of minority sign language in Brazil and Italian deaf have urged on sign language which minority of deaf community. In Italy, sign language was approved however In Brazil, sign language was not approved. Language policy: Language policy does in fact go further than this, for it includes not just the regular patterns of choice, but also beliefs about choices and the values of varieties and of variants, and also, most saliently, the efforts made by some to change the choices and beliefs of others. If you want to find out about the language policy of a speech community, of whatever size or nature, the first step is to study its actual language practices, in other words to describe what Dell Hymes (1974) called the ethnography of communication and what others call the sociolinguistic repertoire or the linguistic ecology. Fundamental to understanding language policy is the realization that all linguistic ecologies are complex contextualized repertoires of linguistic units of various sizes that may be seen as consolidating from time to time into recognizable linguistic varieties that are sometimes accorded a name or label ( Bernard Spolsky, 2005). This comprehension takes some the point. It is momentous of this has been an enormous wave of interest multiculturalism on the part of political philosopher. The language argument take into play a number of concept and appreciation have been traded with vast in the multiculturalism literature, including quality, recognition, freedom, identity, democracy and cultural preservation. Linguistic majority have endeavoured to standardize the utilization of their languages in the public and the protests of other language group. Language planning: Language planning can be divided into three subtypes: status planning, corpus planning, and acquisition or educational planning. Status planning refers to all efforts undertaken to change the use and function of a language (or language variety). The recognition (or lack of recognition) of a language as an official language is part of status planning. The standardization (a codified form) of a certain language or language variety involving the preparation of a normative grammar and dictionary, as well as the modernization of the lexicon, is all part of corpus planning (Trude Schermer, 2012). This comprehension takes some the point. Language planning works in the country in question have been appreciated with the assistance of living literature and detail from experts in the field. The research has particularly concentrated on the status and corpus of exogenous and hazarded languages and on the role of education system in language planning. Background of Brazil and Italy Brazil is still contemplated as a monolingual nation where Portuguese is the language used broadly. However in Brazil there are smaller groups of people speaking other languages. Brazilians utilize all language and want to know about language policy that maintenance language in Brazilian city (Ronice Muller De Quadros, 2012). Schools still support the idea of using the Portuguese language. The Portuguese language has idiom alone that are easy to understand with the fact of existing different Portuguese dialects on language that is critical. India begun to be contemplated in some of company that includes education. The school established the native language, the language of teaching and the student indispensable to the native second language in Portuguese. Brazilian sign language is the language of the deaf community in Brazil that is consisting of the linguistic part of other full-fledged language. Deaf association contain the experts network that is possible to be contacted with dea f people in the country, defending the broadcast the language for people to stay on in Brazilian sign language. In approximately 1980 and 1990, deaf schools utilizing Brazilian sign language that start to refresh the education circumstance the same conditions development. Brazilian deaf community evaluated the language, using Brazilian sign language in Brazil. The linguistic circumstance of Italy is that it is a multilingual country. There is no variation in the dialect in Italy. Particular law that the dialect is to cater the greater status of minority language. The minority language legislate relation that is approved on 15 December, 1999. Italyà ¢Ã¢â€š ¬Ã¢â€ž ¢ linguistic circumstance has been multilingual country. Numerous dialects survive with Italian and the nation language. Dialects have been catered the special status of minority language by lawfulness (law 482/1999). In 1988, Sign language was accepted and approved by first European eleven years ago. The education of deaf people is to separate country in Italy, the city can ability to see Italian sign language. The true has crucial outcome during all language planning. The first parts of status planning; the second, acquisition planning; and the third, issues surrounding corpus planning which is momentous sign language in ltaly. Comparison between Brazil and Italy Linguistic practise and policies depend on the imposition of spoken language which aims at the Portuguese language and one institution the quality model of education achievement in Brazil. Sign language is unimportant and neglect sign language in laboratory, remedial instruction the speed and philosophical and political appreciate which noted deaf education in Brazil. Policies realize the language to the deaf students who decide the languages are contrasting the part of education program. The language desire to survive and they could be successful comprehension and discussion the aim of establishment agreement which we must always discuss to debate with the people who do not comprehend how to be deafness and sign language is momentous. The importance of deaf people is to participant and find out the difference in language of deaf students who are being educated. The Brazilian Portuguese language stress and both Brazilian sign language which have problem. The importance of Brazilian sign language desire only. Brazilian sign language has be representation the same non language last years. It is momentous to value the language for deaf people. Brazilian sign language users started to feel proud of their own language that hearing people comprehended about deaf peopleà ¢Ã¢â€š ¬Ã¢â€ž ¢ the language as protect and annunciate it. Deaf people who should not contemplate the spoken language will be started for Brazilian Portuguese the same an empowering language. Deaf people know bilingual their teachers and interpreter is slowly realize sign language in Brazilian sign language. The Brazilian institutions of geography have collected data and fraction (IBGE 2000) that has to demonstrate the Santa Catarina has had total of fraction 178, ooo deaf student. The Catarina special education foundation (FCEE 2007) which reported only 1680 the same they will be catered to the classroom in school and 1 percent of the total number has identified from IBGE will being catered. Brazilian sign language is utilized and promotes contact middle deaf people (RONICE MÃÆ'Å“LLER DE QUADROS, 2012). Deaf students who are enormous majority the contact with people who realise a few sign language and utilise it from little communicate goal the deaf students. The teachers have awareness their own language that Brazilian Portuguese demonstrate some possibility error the implantation of the bilingual education policy and the representation of language for deaf education. The enormous plurality of teachers who started working and their interpreters felt ashamed. They realised their restriction of concept in sign language. The research promise middle 2001 and 2002 total of number sign language interpreters that contemplate the expert in both language (Brazilian Portuguese and Brazilian sign language) tell the result translation from Brazilian Portuguese to Brazilian sign language for the classroom. Status planning: To know the influence of institutions and organizations, need the United Nations and the European group of people who have urged on to recognise the nation sign languages of their deaf communities. The public have discussed Italy sign language that was not outcome of fact by nation parliament. It is most the pertinent enthusiasm was the appeal sign from university professional and researchers have worked include part of linguistic, language, philosophy of language, psychology of language and communication. The Italian parliament planned to sustain the suggestion of recognition of Italian sign language that the Italian deaf community have minority the language in 2005. Deaf people have national association which is initiative to urge on Italian sign language. This organization is the most momentous referent for deaf people who have relationship with state institution. The academic community concern in LIS and deaf world has not been restricted to the linguistic of LIS . LIS communication system have utilised the relation grammar has flash the concern of researcher work on computer for linguistic, natural language process of animation. The Italian linguistic society have meeting of annual and include paper formal fact the sustain of LIS that has been approved (September 28, 2011). Acquisition planning: LIS sight becomes both deaf and hearing communities. He reviews the four main of acquisition planning from LIS which have bilingual education program. LIS have worked the course structure and worked with LIS. Deaf children have circumstanced in education that is approved by law in 1977 (law no. 517/1977) that it s mandatory for all children with disabilities to have accuracy to attend mainstream school, which would cater to make a suitable and sustainable method for them towards actual integration. The objectives of the project are ongoing to cater a particular education program from deaf children specific school. It benefit the experience specific school which are still candid model of education that fortunately integration deaf and hearing children. Deaf students who recognise that ASL can bring the classes in LIS for Italian deaf culture. Italian culture has taught in ASL which courses are urged on from LIS signers. Quality of interpreters are being asked by deaf people who decided that interpreters have the expert knowledge of communication potential of LIS and training of interpreters have to be more better. Corpus planning: LPP mostly concentrate on actual inner to the language system that accosts the momentous issue of normalization course and language documentation is appropriate to comprehend the actual linguistic circumstances and benefits in LIS. Preparatory studies on difference in LIS which have main concentrated in lexical difference and phonological process concerned to historical shift (Carlo Geraci, 2012). Corpus planning that LIS is comparatively well document sign language. In particular, an enormous corpus of deaf children have learnt LIS which their first language and corpus of hearing adult have learnt LIS that their second language. Conclusion This is comprehended that topic have two contain in comparison. It is momentous of sign language legislature in Italy. Some of deaf children have entered to LIS which their first or native language. Oralist educations are disagreed to sustain utilization of the LIS that is getting rural job chances for deaf people. The academic strongly sustain the research on LIS and deaf culture. The endeavours have conducted to the elaboration of beton planning in LIS. This is understandable in status and acquisition planning. Brazilian institutions have succeeded a needful law implement from the headway of public policies concern to the consolidation of Brazilian sign language. Deaf association is important for deaf peopleà ¢Ã¢â€š ¬Ã¢â€ž ¢s structure of their identity, acquires formal lawfulness through the identification of Brazilian sign language. The materials translated into Brazilian sign language in sundry educational space lawfulness to the right of access to one. Deaf leaders are offerin g a deaf bilingual education which is substantive of specific school with hearing children who have to be integration for deaf children in education. It is impossible to apply for system in India that is unimportant of sign language lawfulness in India. Oralist educations are agreed to support uses of the language however sign educations are disagreed to support utilization of Indian sign language. Deaf people minority was not accepted in ISL by government. Because importances of utilization bAASLS hope to become awareness about policies and planning language, it has time to be future and conceive in ISL next ten years.

Terrorism and Game theory :: essays research papers fc

Terrorism is a rare, broad concept that affects individuals, schools, corporations, and governments alike. Generally terrorists end up wanting to make change with governments, and governments are usually the only groups powerful enough to try to deal with governments. But what should be the best strategy to deal with terrorists? Since September 11, 2001 game theory has been used to analyze how governments and how terrorists should act to achieve their best outcome. This paper will analyze the games that these competing forces can use to determine the best course of action.   Ã‚  Ã‚  Ã‚  Ã‚  The current war on terrorism is tending to have three different sides: the United States, the European Union, and the terrorists. Before the September 11th attacks all policies towards terrorism were reactive rather than proactive. So before we get involved with terrorists at all, there is a game in which based on what policy the EU is going to enact, the how should the US act towards terrorism. A proactive policy means that the government is going to attack POSSIBLE terror threats, whereas a reactive policy would mean that there would be no strikes against terrorism unless the terrorists decide to strike first.   Ã‚  Ã‚  Ã‚  Ã‚  Now lets take a look at a model. Lets say, for analysis sake, that a proactive strategy costs a government 6, but casts a benefit of 4 for both governments. For example, if only the US has a proactive strategy, then it’s net would be -2, but the EU would get all 4 of benefit. If both governments are proactive, then the cost is still 6 for each, but the benefit is doubled to 8 because they benefit from each other’s policies. Using this structure, we can construct this normal form of the game:   Ã‚  Ã‚  Ã‚  Ã‚  from Acre & Sandler Vol. 34 In this model it is clear that the Nash Equilibrium is where neither government has a proactive policy towards terrorists. Because neither government is willing to bear the entire cost, neither government will be proactive although the largest benefit can be derived from both being proactive. This is why this is a type of prisoner’s dilemma game. Real life is hardly ever as fair as this model would suggest. The United States is the target of 40% of all terrorism in the world. (Oster) The US is also more often successful in thwarting terrorism than Europe. Thus, a more realistic model might be one in which the United States gets a benefit of 8 for it’s proactive strategy.

Alzheimers Effect On The Brain Health And Social Care Essay

Alzheimer ‘s disease is a progressive neurodegenerative upset of the encephalon that consequences in damage of memory and decrease in the ability in logical thinking, planning, linguistic communication, and besides perceptual experience. [ 3 ] It is considered as one of the most common types of dementedness and it accounts for an estimated 60 to 80 per centum of instances. This is due to the increasing figure of impairment of nervus cells in the encephalon. Therefore, figure of synapses lessenings and causes the information transportation at the synapses begins to neglect lead to cells dice. [ 2 ] There are several hazard factors in this instance. Most experts agree that the greatest hazard factor for Alzheimer ‘s disease is progressing age but it is non a normal portion of aging. [ 2 ] Besides, it has been proven that Alzheimer ‘s disease is caused by a combination of factors, including familial heritage, environmental factors, diet and overall general wellness significance that no individual cause for it. [ 7 ] There has no current remedy for Alzheimer ‘s disease and no proved intervention to decelerate its patterned advance. However, interventions for symptoms can so be used to detain its oncoming. [ 5 ] Therefore, to get the better of the increasing figure of developing Alzheimer ‘s disease, I have considered the usage of cholinesterase inhibitors ( 287 ) The symptoms of Alzheimer ‘s disease can be divided into two chief classs which are â€Å" cognitive symptoms † and â€Å" behavioural and psychiatric symptoms † . I would wish to concentrate on the intervention for the cognitive symptoms which affect memory, linguistic communication, opinion, planning, ability to pay attending and besides other thought procedures. [ 3 ] Cholinesterase inhibitors are effectual in increasing the degrees of acetylcholine in the encephalon, which is critical in memory and acquisition. They delay the oncoming of declining symptoms for 6 to 12 months in about half of the people who take it. [ 9 ] FDA has presently approved the usage of four cholinesterase inhibitors, tacrine, donepezil, rivastigmine and galantamine. [ 11 ] Some of these drugs work best in the earlier phases while some are reserved for the ulterior phases. In clinical surveies, all cholinesterase inhibitors work every bit good by increasing the sum of acetylcholine in the encephalon or by heightening nervus cell ‘s response to it. [ 10 ] Among all, donepezil is the lone drug that can be used to handle all phases of Alzheimer ‘s disease, from mild to severe. It is taken one time a twenty-four hours and has modest benefits at best. However, persons with Down ‘s syndrome who are over 40 old ages old are excluded as the karyon basalis of Meynert in patients with Down ‘s syndrome contains fewer nerve cells than in normal comparing topics. This causes the symptoms of Alzheimer ‘s patients with Down ‘s syndrome to acquire worse. [ 18 ] ( 529 ) â€Å" The efficaciousness of donepezilA was demonstrated in a 24-week double-blind survey in which patients with mild to chair AD were indiscriminately assigned to donepezil ( 5 or 10 mg/day ) or placebo. Cognition, as measured by the Alzheimer Disease Assessment Scale, cognitive subscale ( ADAS-cog, and the Clinician ‘s planetary evaluations were significantly improved in both intervention groups compared with placebo. There was no consistent consequence noted on patient-related quality of life steps. † hypertext transfer protocol: //www.uptodate.com/patients/content/topic.do? topicKey=~iqpTJo3u3dzUoc, retrieved on 5 September 2010 The initial dose should be started at a lower sum which is 5mg one time day-to-day for donepezil and increased to 10mg daily after one month of ingestion. Then, the titration can so be preceded to the maximal dosage. There is grounds shown that patients with higher doses had better results compared to those with lower doses. However, patients with maximal dose should be carefully monitored to avoid any side effects such as sickness. If patient with maximal dose achieved satisfactory consequences so it should be continued. [ 19 ] The above graph shows that the alteration from baseline on ADSD ( Alzheimer Disease Assessment Scale-cognitive subscale ) of donepezil and placebo group. [ 15 ] ( 739 ) The cholinesterase inhibitors although non the remedy, there are benefits shown that bettering the symptoms even for advanced Alzheimer ‘s disease. However, the exact doses need to be on a regular basis monitored to extinguish the side effects of cholinesterase inhibitors. [ 16 ] These medicines do non work for all patients ] Without ongoing usage of cholinesterase inhibitors, status of patients will deteriorate over a period of 4 to 6 hebdomads until they reach the same point where patient has non taken the drug. [ 17 ]Social and Economic ImplicationPatients with Alzheimer ‘s disease tend to bury things easy due to the increasing figure of nervus cells deteriorate. Therefore, they may bury to take their medicine and causes unwanted consequence. Most of them will happen it hard to keep a occupation or even care for themselves and therefore causes great load to households and friends, particularly their loved 1s. Furthermore, patients will experience down when they are con fronting more and more trouble pass oning about their experience. As a consequence, symptoms of unwellness go undetected and cause infection in other variety meats and therefore physical uncomfortableness may be expressed through behaviour. The drugs do work when the knowledge is maintained ; patients can retrieve better and be able to get by with behaviors. Hence, health professionals, friends and household are playing imperative function in supplying aid and support to person covering with Alzheimer ‘s disease. In add-on, patients require great attachment to intervention which would do immense fiscal load and economic impact. Harmonizing to WHO, Alzheimer ‘s disease is the most dearly-won compared to other major chronic conditions. [ 20 ] The betterment after utilizing medicines might be minimum. However, some surveies show that these medical specialties do assist in a long tally. [ 21 ] For illustration, donepezil 10mg day-to-day costs around A $ 400.64, though expensive but deserving with high effectivity. [ 22 ] Like other diseases, Alzheimer ‘s disease patients need ongoing intervention as betterment will worsen after halting taking in medicine. This would take to uninterrupted cost and therefore finance from other healthcare resources is extremely desirable in this instance. ( 1065 )The chart shows that the cost for handling Alzheimer ‘s disease is the highest. [ 20 ]The graph above shows that the cost for caring of people with Alzheimer ‘s disease is expected to increase for the following 40 old ages. [ 23 ]( 1143 )Benefits and HazardsCholinesterase inhibitors are effectual in bettering knowledge, behavior and therefore cut downing health professional emphasis. [ 24 ] This is due to the increasing sum of acetylcholine though they can ne'er change by reversal the devastation of encephalon cells. Improvement with these medicines might be minimum but people have the opportunity to take meaningful lives once more with the better memory and thought abilities. However, they might besides enforce side effects to human wellness such as dyspepsia, loss of appetency and weight loss. Therefore, exercising and balanced diet are besides of import. Regular physical exercising can take down the hazard of Alzheimer ‘s because it may profit encephalon cells by increasing blood and O flow. [ 25 ] The chief job is caused by the dose titration. Every titration should be started at low titration and if necessary merely preceded to maximal dose to obtain maximal status. Most of the drugs are used to handle mild to chair except for donepezil which can used to handle all phases. Furthermore, these medicines are non recommended for usage in MCI ( Mild Cognitive Impairment ) as grounds shows the increased hazard of injury, including decease. [ 19 ] Furthermore, some patients tend to bury to take these medicines for the interest of extinguishing possible side effects. This consequences in the impairment of status of patients and increases the hazard of backsliding of symptoms.

[ 7 ]( 1426 )Alternate TreatmentsMental Stimulationâ€Å" Harmonizing to the 2008 Wall Street Journal reappraisal â€Å" Neurobics and Other Brain Supporters, † A an active, stimulated encephalon reduces your odds of developing Alzheimer ‘s. Those who remain engaged in activities affecting multiple undertakings, necessitating communicating, interaction, and organisation, who continue larning, and invar iably challenge their encephalons earn the greatest protection. † hypertext transfer protocol: //www.helpguide.org/elder/alzheimers_prevention_slowing_down_treatment.htm, retrieved on 7 September 2010 Alzheimer ‘s disease can ne'er be cured but it can be prevented or delayed by this method. Mental stimulation is well-known for non merely a powerful preventative manner but can besides decelerate down the disease. Surveies carried out in China have shown that nonreaders were five times more likely to get AD than high school alumnuss. [ 27 ] Besides, this intervention was supported by a Chicago survey affecting 90 patients. It was reported that those patients who got frequent cognitive activity were approximately 0 % less likely to develop Alzheimer ‘s disease than those with small or no cognitive activity. [ 31 ] Any signifier of mental exercisings such as playing cards, Sudoku or even analyze a foreign linguistic communication can maintain on supplying encephalon to larn something new every twenty-four hours. Besides, memorisation can be practiced. For case, rimes and forms can be created to beef up memory connexions. [ 26 ]Electroconvulsive Therapy ( ECT )ECT is a tech nique that induces a ictus by directing electric current to the encephalon of patients causes alterations in the encephalon chemical science when patients are given muscular relaxant. However, it can do impermanent short term memory loss despite being really effectual in handling terrible AD. [ 28 ] Unilateral ECT is believed to do less memory loss compared to bilateral ECT. [ 29 ] ECT is done when all the possible interventions fail. Harmonizing to Vaughn McCall, professor and president of ( 1718 ) the Department of Psychiatry and Behavioural Medicine, â€Å" Quality of life and map are improved in ECT patients every bit early as two hebdomads after the decision of ECT. â€Å" [ 30 ] Therefore, the ability of operation of encephalon can therefore better. NICE, an arm of Britain ‘s National Health Service, said ECT should be used â€Å" merely to accomplish rapid and short-run betterments of terrible symptoms after other intervention options have failed and/or when the status is considered to be potentially life endangering in persons with terrible depressive unwellness, catatonia or a drawn-out or terrible frenzied episode. † hypertext transfer protocol: //www.sciencedaily.com/releases/2004/11/041104011942.htm, retrieved on 7 September 2010EvaluationThe purpose of this website hypertext transfer protocol: //www.alz.org/alzheimers_disease_what_is_alzheimers.asp is to supply information about Alzheimer ‘s disease and to extinguish it through the promotion of research.

Agar Cube Lab Report Essay Example

Agar Cube Lab Report Essay Example Agar Cube Lab Report Paper Agar Cube Lab Report Paper Hypothesis: I expect to find that when the surface area o volume of a cell reaches a certain level, diffusion alone wont be able to supply the cell materials needed, and as single-celled organisms take in and release substances by means of diffusion across the cell membrane, this process limits cell size. I predict that as the rate of diffusion will be too slow to deliver materials to the center of the cell in the larger cells, it could result in cell malfunction. Variables: The independent variables are the dimensions of surface area to volume ratio of the agar cube. (1 CM, 1. CM,CM) The dependent variable, the variable am observing/recording, is the time of diffusion (Noah turns the agar cube pink as it disperses into it). The controlled variables will be keeping the concentrations of the Sodium Hydroxide constant, to use agar jelly from the same batch. Also, theres the room temperature which is kept constant and the room pressure. Materials: 250 ml beaker Measuring tape Dull knife Stirring rod Phenolphthalein agar cubes (xx CM, 1. CM,1 CM) Hydrochloric acid (1 m) Paper towel Ruler Procedure: 1- Obtain agar cubes and hydrochloric acid from your lab instructor. Cut the bubs so that one has a length of 1. 00Â ±0. 05 CM, another 1. 50Â ±0. 05 CM, and the 3rd 2. 00Â ±0. 05 CM. 3- Examine the cubes closely and then place them in the ml beaker. As we can see the cube with the largest surface area and volume has the smallest surface area to volume ratio. If the surface area to volume ratio gets too small, then the substances wont be able to enter the cell fast enough to fuel the reactions, because the surface area controls the rate of the exchange of materials while as the volume grows larger it will need more materials to enter and exit, in a more quicker rate, therefore waste products will start to accumulate within the cell as they will be produced faster than they can be excreted. In addition, the cells will not be able to lose heat fast enough and so may overheat. This was concluded from the experiment, where as the Agar cube dimension were larger, the rate of diffusion was much mallet from the Agar cube with the smaller dimension, where the last had a larger V: AS ratio than the larger cube. Errors and Improvements: Error Improvement Parallax error, resulting in a misreading in volume. This is caused by reading the volume readings from an angle, thus to solve this error, readings must be read at the human eye level, where the meniscus being measured at and the eye, are at the same horizontal level for accurate reading intakes. The measuring cylinders that were used for the HCI were not divided by the same rate of division. Use the same type of cylinders for all trials, like a limerick cylinder to measure the amount of aqueous (HCI ) more accurately. The sizes of the cubes were not exact as mentioned ( Ex: 1 CM is not exact ) and as a result the results obtained may not be very accurate. When cutting, a more precise instrument must be used. If no other instrument is found, a more sharper knife can be used accompanied with a more specific ruler. Injury of the surface of the cubes due to hard stirring by the rod. Stir at a slower rate for a longer time than stirring hard for a little time, in addition to that a thinner rod can be used for stirring.
