Does Caffeine Affect the Heart Rate Essays

Does Caffeine Affect the Heart Rate Essays Does Caffeine Affect the Heart Rate Paper Does Caffeine Affect the Heart Rate Paper Aim: The aim of this investigation is to investigate the affect of caffeine on the heart rate of Daphnia (Water Fleas). Hypothesis: The heart rate of the Daphnia will increase when exposed to caffeine. Caffeine acts as a stimulant, which causes stimulatory neurotransmitters to be released in excess amounts. This makes the brain feel more alert and also increases mental activity. Therefore an increase in the heart rate is likely if more physical activity is taking place. Method: 1. Set up apparatus needed- 6 Daphnia, cavity slides, dropping pipettes, distilled water, caffeine tablets, cotton wool, glass beakers, test tubes, test tube rack, stop clock, filter paper, and microscope. 2. After equipment is set us, collect 6 Daphnia. Place 3 into pond water and 3 into caffeine solution. 3. Then place a thin layer of cotton wool onto the slides under the microscope. 4. Collect one Daphnia from the pond water, using the pipette and place onto cotton wool. Looking under the microscope, time its heartbeat for 15 seconds using a stop clock and record. 5. Wait for 2 minutes and then record the heartbeat again for 15 seconds. Ensure the stop clock is running continuously throughout. 6. Record the heartbeat of the Daphnia every 2 minutes for 15 seconds until you have recordings for the start, after 2 mins, 4 mins and 6 mins. 7. Repeat steps 4-6 another 2 times. This will ensure the results are reliable as the experiment would have been repeated several times. 8. After having repeated the experiment, change the cotton wool and repeat steps 4-7, this time using the Daphnia from the caffeine solution. Risk Assessment/ Safety: Wear gloves when working with biological specimen and ensure you wash hands after the practical as they may contain bacteria which could spread causing harm to others. Also make sure you wear lab coats in case of any spillage onto your clothes. Use goggles again to protect eyes, in case of spillage. Also wipe down surfaces and wash hands with anti- bacterial sprays/ soap to clean away any bacteria. Ethical Issues: Try to ensure that the Daphnia stay alive after use as they are living creatures too. To ensure the Daphnia stay alive, use pipettes when transferring the Daphnia from the solution, to the microscope and back into pond water.

Helping Autistic Students Shine in Mainstream Classroom

Helping Autistic Students Shine in Mainstream Classroom A type of neurodevelopmental disorder, autism delayed an affected child’s cognitive and language development by altering how nerve cells and their synapses (a structure that allows nerve cell to communicate with another cell) interact and organized. Delayed development in autistic children often results in other later life difficulties such as poor social and learning  skills. The Impact of Delayed Cognitive and Language Development in Learning Autism in children commonly occurs before the age of 3 and its common symptoms include child’s gradual withdrawal from social relations, deteriorating verbal skills, and repetitive stereotypical behaviors such as head-banging, spinning, rocking, hand-flapping, and so on. However, results of a recent study suggest the frequent vomiting, diarrhea, and infections among children are also symptoms of autism. Autistic school aged children are rarely placed in traditional classrooms due to their poor social skills and anxieties over a large group of people. Moreover, since autism has a profound effect on thinking and learning ability, they usually attend special classes and taught with teaching methods designed for specific impairments caused by the autistic disorder. However, teaching children with autism outside mainstream school classroom, according to study, does not resolve their difficulties in socialization, communication, thinking, and behavior. In fact, this type of arrangement deprived them opportunities to communicate, relate ideas, build social relationships, and cope with different social situations. Moreover, although most children with autism are not interested or appreciate social contacts, teaching strategies must remain socially oriented and instead of tolerating unhelpful attitude and behaviors provide opportunities for interaction and social skills development. You may also like these articles: Bright Sides of Academic Intellectuals We Call Nerds The Contribution of Academic Institutions in Childrens Well-Being Developing Students Creativity and Self-Expression through Crayons Learning Moral Values in College Movies Single-Parent Children Behavior Providing Opportunities for Communication, Interaction, and Confidence Building It is important to remember that socialization; communication, thinking and behavior are the most common difficulties experienced by students with autism thus teaching strategies should resolve all these issues simultaneously. Special classes, for example, satisfy autistic students’ need for isolation rather than identifying causes and reducing difficulty in developing a social relationship, encouraging communication and promoting positive thinking and behavior. Students in mainstream school classrooms have different perceptions in life but we should dwell on the reality that humans are passionate about sharing and often find fulfillment in helping others in need. Since most students with autism, regardless of teaching methods and classroom category, consistently need the support of those who care and understand their needs, teachers may find encouraging non-autistic and kindhearted students to help their less able peers beneficial in terms of social and cognitive skills development. For example, the perception and attitude of students with interaction problem may be improved by their peers interest and enthusiasm to interact with others. Similarly, since most children with autism disorder avoid social interaction due to lack of social skills and knowledge on how to make friends, behave in different situation, interpret peers’ expression and intent, and comply with social rules, a classroom filled with interacting, enthusiastic and cooperative students can deliver helpful social cues that they can put into practice when similar situation comes their away in the future. Inclusion education for students with autism can provide the opportunity to learn alongside peers in mainstream schools. It can deliver positive social cues that people with disabilities are not singled out or considered different in our society. It can help gradually develop a sense of community among autistic students, eliminate anxiety over a lack of social skills, increase enthusiasm for learning, and later shine through class performance and achievements.

Rhetorical analysis Essay Example | Topics and Well Written Essays - 1000 words - 2

Rhetorical analysis - Essay Example As a function of this particular means of analysis, this student will seek to provide feedback and analysis of personal reaction, a description and discussion of the audience that this announcement is appealing to, the underlying purpose, and the means by which individuals within the announcement are ultimately represented. In seeking to address each of these rhetorical issues, the student can hope to gain a more appropriate and well nuanced understanding of the motives and mechanisms that lie at the very heart of this specific public service announcement. Furthermore, by attempting to draw inference on each of these issues, it is the hope of this student that the reader and/or researcher will better to be able to understanding the public service announcement through the lens of analysis which will be presented. Firstly, with regards to this student’s reaction to the given piece, it was one that was immediately drawn to the high definition portrayal of a given setting with see mingly infinite small details occurring in rapid order within the field of vision of the viewer. This particular technique helped to build the suspense, in conjunction with the melodramatic music which was playing throughout the Public Service Announcement (PSA), and lead the viewer to focus solely on trying to locate the â€Å"reportable incident† that the text, speech, music, and setting foreboded. Similarly, with respect to the given audience for this Public Service Announcement (PSA), the viewer can assume that this extends to all citizens of responsible age. Such a broad generalization can of course be made due to the nature of the information that the PSA is trying to integrate with the viewer. As such, maximizing shareholder input is of course a primary interest to the individuals responsible for making the film (See Something Say Something Campaign, 3). Although each of the rhetorical levels of analysis which will herein be included are important, it is arguable that the very most important one is that of the rhetorical appeals that the PSA makes upon the viewer. The most powerful of these is the way that the PSA tugs upon the emotions of the viewer. This is affected by representing situations in a seemingly normal way; however, through utilizing sinister motives, references to the prior attacks of September 11th, the way in which our current world has changed, and the strong and ever-present feeling that there is something lurking beneath the surface, the PSA is able to engage the emotions of the viewer in a way that would otherwise not be possible. Moreover, by using images and slight of hand camera work that tells a story within a story which ultimately has a connection to a larger story (terrorism), the viewer is even further engaged as to the means whereby they can stand to affect a difference on this action being perpetrated within the world in which they live. This is interesting and powerful due to the fact that the PSA does not make any mention of a particular time or place. Instead, the instance itself and the ramifications thereof is enough to engage the shareholder to give up information to the authorities as a function of protecting themselves and society. With regards to the purpose, as has been stated up until this point, the purpose is to shock the viewer and spur a degree of future action based upon the representations that are alluded to on the screen. In this way, the filmmakers seek to

Discussion Posts About Type II Diabetes And FASD Essay

Discussion Posts About Type II Diabetes And FASD - Essay Example Efficient diabetes management needs demanding and continual self-care procedures and behaviors in various areas. For instance, measuring and testing glucose level, diet control, information update about diabetes from library and insulin injection. The patients are expected to record all the results obtained. Text messaging makes it easy for patients to send the blood glucose results to their doctor on time and in response receive intervention feedback to support self-care management (Sarnikar, Bennett & Gaynor, 2013).Discussion two I agree with Katherine Johnson that the introduction of FASD topic in high school sex education is effective in lowering the number of babies born with the disorder. Effective strategies to minimize FASD comprise of comprehensive and early education about the hazards of alcohol intake during pregnancy. In order to minimize the number of babies born with FASD, prevention is the best alternative. Sex education programs provided in the private and public scho ols is a suitable venue to teach about FASD (Miller, Blumenthal & Chamberlain, 2015). Such a program can assist in implementing CHOICES, which is a program for women about selecting healthy behaviors to prevent alcohol-exposed pregnancies. The teenagers can access information that assists women to learn how to abstain from alcohol and use birth control techniques effectively. In addition, the youth will benefit from addiction rehabilitation and correctional settings (Hanson, Wilton, & Langland, 2015).

Creoles & language evolution process Essay Example for Free

Creoles language evolution process Essay Creoles have generally been considered to have more complex formation processes than pidgins, which lie at an earlier stage in the language evolution process (Culpeper, 1997). The processes that drive the development of creoles and pidgins have been the subject of interest and debate to linguists for many decades. Some have hypothesized that the development of these forms has been driven by variables similar to those that drive the creation of languages. Some of these hypotheses have included biological approaches to creole and pidgin evolution, while others have posited synchronic methods (Adone Vainikka, 1999; Bickerton, 1999). Many of these synchronic and biological ideas are compelling highly challenging in their plausibility, employing ideas related to Universal Grammar as a means of illuminating creole and pidgin development. The development of pidgins has been considered to be less difficult to understand than that of creoles, mainly because of the precise phenomenon that pidgins describe. As a language form that develops from the mixing of two distinct languages, many have simply considered it to occur as a result of the mixing of two (or more) people groups that possess distinct languages. Yet, some complexity exists in the different scales to which pidgins might develop (Adone Vainikka, 1999). Furthermore, it is interesting to note that when the languages of a bilingual child develop, even at an early age, that child generally distinguishes between the two perfectly without mixing them (Culpeper, 1997). When languages exist together on larger scales could be when pidgins are more likely to develop, and this appears to stem from the likelihood that the multiplicity of languages is intelligible by a wider range of persons. When this is the case, it creates no real need for any one speaker to make the effort distinguish between them for purposes of being understood. Despite the fact that pidgins and creoles are distinct language forms, many consider pidgins as a form that occurs on the way to the formation of a creole. In fact, the definition of creolization given by Adone and Vainikka is â€Å"the process by which pidgins develop into creole languages† (1999, p. 76). Discussions regarding the relationship that creolization bears to language acquisition processes and language development have led to two distinct schools of thought. One has viewed creolizaiton as being an extended process that takes several generations to mature. Indeed, this process never ends but continues to develop alongside the development of the particular culture in which it occurs. The other school of thought has viewed the process of creolization as on that has the potential to occur suddenly, within only one generation (1999). The gradual development of creoles appears to be more consistent with the prevailing theories of language development. If creoles are viewed according to the definition above (as a product of pidgin development) then it would appear that such a fast development of the language would be very difficult. Such speedy development would afford little time for the creation of the pidgin itself before its further evolution into a fully developed creole. The mixing of more than one language appears to be a phenomenon that would take quite some time, as this would involve a certain degree of standardization concerning which parts of each language should be included in this pidgin. In addition, it would appear that more than one generation would be needed to allow the general spread of this understanding among the population. However, it would also seem that geographical and population-density concerns would have a bearing on the ability of the creole to develop and suffuse an entire region. It may also depend on the demographic of the individuals who act as the agents of this development. Those theorists who believe that creolization has the potential to develop within one generation have cited young children as being the agents of such change (Bickerton, 1991, cited in Adone Vainikka, 1999). This researcher argues that this form of â€Å"radical creole† develops through a Bioprogram that operates very closely with the theory of Universal Grammar. Such a development, therefore, is based on humans’ innate understanding of language, which is to some degree distinct from the language that is learned in any given cultural context. Because this theory posits humans as having a relationship to grammar that transcends the grammar rules of any given language, the development of a particular radical creole would be based on the similarity of the language variation put forth by each child despite the fact that they may not grow up in close proximity to each other (1991; 1999). This particular view of creolization is based on language evolution theories that take a biological or even genetic approach to language change (Mufwene, 2001; 2006). In the creole form used in Mauritius, for instance, the children have been found to make fewer â€Å"mistakes† that represent a non-conformity to the language than those found in many standardized, non-creole language (Adone Vainikka, 1999; Bickerton, 1999). Bickerton writes, â€Å"Children acquiring English and other noncreole languages make a number of â€Å"mistakes,† a very high percentage of which would be fully grammatical utterances if the children were acquiring a creole language† (1999, p. 66). The opposite of this does not appear to be true—children acquiring creole languages do not make as many mistakes that would be considered grammatical in a noncreole language such as English or French (1999). It would seem therefore that creole might be considered a more naturally occurring form of a given language as distilled through the human’s biological propensity toward language expression. However, while this supports the idea of Universal Grammar, it does not appear to offer much support of radical creolization, as the Mauritian Creole has been evolving for many generations. Creoles and pidgins are interesting in that they offer insight into the earlier stages of language development. Many ideas exist concerning the classification of these language forms. Theories also exist concerning how such forms are developed, as well as the relationship they have to each other and to the languages on which they are based. Biological and synchronic approaches have both pointed toward the idea of Universal Grammar as having a bearing on the development of these forms of language, and intriguing (yet inconclusive) discussions have come about as a result of research done in that direction. .

Price of Glory A new movie called "The Price of Glory" is opening Friday, March 31,2000 all over. However, this movie will only be out for two weeks, if the community does not support it. This a movie about a Latino boxing family and it is refreshing to see a movie about a Latino family where the roles are actually played by Latino actors. The movie stars Jimmy Smitts, Jon Seda, and Paul Rodriguez in a role you wouldn't expect. We got the chance to preview the movie last night and it is a great movie with a lot of comedy and still very heart-warming. An actor from American Me was there promoting the movie and he said that the African-American community has organized a group called the Weekend group and every time a new movie comes out starring an African-American actor or director over 2 million people go to the opening day and support the movie.They are trying to get a similar group started in the Latino community. Actor or director over 2 million people go to the opening day and support the movie.They are trying to get a similar group started in the Latino community. If you are tired of seeing us in roles of gang-bangers, gardeners, housemaids, here's a chance to do something about it and enjoy an excellent movie. The movie will not be getting a lot of publicity at all so spread the word, and if you see it and like it, go see it again! If it makes a difference, OZOMATLI is on the soundtrack!: Pass the word.

It is an excellent movie. You really have to go see it. At the premier they announced that the movie will begin showing on March 31st. They told us *how important it is to go see a movie the first two weekends that it is out.

Guillermo Financial Analysis Essay

Making a sound financial decision is a vital component of the success of a business. The business must conduct market research, description of products, services and marketing strategies, and setting principles for the business’s success. Expenses should be noted prior to writing a financial plan. The goal of a business is to operate on a predefined budget. Ensure there are no undefined or hidden cost that could cause problems later. The business plan helps the business to make day-to-day decisions on its operations. Teamâ€Å"D† will analysis Guillermo’s alternatives and make a recommendation on which alternative will enhance the businesses financial decision. Maintain Current Operational Levels One option available to Guillermo is to make no adjustments to the company’s current operations. This option supports the top concerns of acquisition from a larger firm and spending a large amount of cash on high-tech equipment investments, it does not solve the problem of a shrinking profit margin because of a rise in labor costs. Supporting the option to maintain current operations overlooks potential opportunities that are identified to allow the company to move away from its primary manufacturing role and act as a distributor for the Norwegian competitor. According to the assets, liabilities, and equity information provided by the University of Phoenix, sales growth is slowing to 1% from previous periods. These low profit margins willnot sustain Guillermo in the long-term;they will not improve if there is not a choicemade to adjust to the financial situation. Maintaining current operations does not address the shrinking profit margins. To continue to move Guillermo furniture in a positive direction, Mr. Navallez needs to apply some options already available and within the current operating structure. One option available to Guillermo is expanding the patented flame retardant process already in use within the manufacturing process, by applying a similar coating. This option requires no additional investment because Guillermo owns the equipment as part of the existing manufacturing process. The new coating adds value to the furniture, and makes it more appealing to consumers (University of Phoenix, 2009). The net present value of the project must be calculated in order todetermine ifthis is a strong option. For planning and budgeting purposes, a three-year life cycle is assumed for the coating project with an initial investment cost of $222,705 that is absorbed during the first year of the project. This produces a projected cash flow of $1,733,562, leaving Guillermo with a net income profit of $42,557. Net present value for the three-year project calculates to $197,171. Another option available and immediately implemented is to reduce inventory by quickly turning over products, thus increasing the cash flow. Planning an accurate budget supports the inventory overhead by reducing costs associated with maintaining inventory. The flex budget data shows that Guillermo furniture underestimated June operating expenses by $101,740. If these costs estimates were more closely tied to production costs, a substantial amount of cash would have been available to reinvest in other areas of the business. Closely managing this inventory will make more cash available for expansion in other areas of the company. Last year Guillermo experienced a $3,671 increase in its year-end inventory. Keeping a large amount of inventory on hand ties up cash, which otherwise can be investedin other areas of the business. Guillermo’s option to hold fast and maintain current course is setting the conditions for failure. However, to maintain its current course and improve its financial standing, Mr. Navallez can leverage small opportunities that maximize the financial condition by leveraging the existing patent and reducing inventory. High Tech Business Upgrade Guillermo’s high tech alternative is based off a process currently being used by one of the Norwegian competitors. It will allow the business to increase productivity but will also require a more skilled worker to operate the machinery. In choosing this alternative it predicts that sales will increase by 50% bringing in an increased revenue stream (University of Phoenix, 2009). In assessing this alternative looking at the net present value of future cash flows will help make this decision an easier one by noting the value it brings to the organization. Assuming that Guillermo expects to see a return on the investment within three years, this time period will be used in calculating the NPV. Using the three year time period with an interest rate of 7. 5% and a growth rate of sales at 1. 0403% the NPV can be calculated at $617,178. The firm’s predictions on projected sales has not been the most accurate when looking at historical information. Conducting a sensitivity analysis will further help to determine the value of this alternative using the net income as the adjusted variable. Assuming there will be a best, worst, and most likely outcome to future sales revenue, the projected sales number of $195,564 will act as the most likely outcome. By increasing this number by 10% and decreasing it by 10%, the best case and worst case scenarios can also be calculated respectively. These numbers will show how sensitive the NPV calculations are to the changes in net income. Under the best circumstances high tech alternative yields a net income of $215. 120 while the worst yields $176,008. These numbers translate into net present values of $617,486 under the best circumstances and $616,870 under the worse circumstances. If Guillermo decides to use the alternative funding for the expensive machinery becomes an issue. There are three main ways in which to fund the purchase of this equipment and the additional cost of employee labor. The additional costs can be self-funded if the available cash is available. This will increase the equity in the firm but this will also reduce the leverage the company currently enjoys. The company’s equity can be used to purchase the equipment. This will have the same effect as if Guillermo used personal funds since he is the sole owner of the furniture company. The equipment can be financed through secured debt financing which will increase leverage as well as provide additional tax benefits to the organization. And lastly, Guillermo can lease the equipment. Each of these alternatives provides unique tax benefits as well as pros and cons specific to each of these options. As Guillermo considers this alternative in comparison to other options the cost of maintenance, salvage costs, depreciation costs, and increased labor costs should be factored. These all impact the overall capital budgeting decision faced by Guillermo Furniture. Distribution/Broker Opportunities Guillermo’s second alternative is to become a broker for one of the Norwegian competitors. The company has been looking for channels to distribute in North America as it has chosen not to operate furniture outlets but instead to rely solely on chain distribution (University of Phoenix, 2009). Guillermo’s existing business relationships afford him the opportunity to coordinate a distributor network that generates a new form of revenue for the company. This new stream of income can help offset some of the financial challenges that have emerged as a result of a competitive furniture market and increasing costs. In addition to becoming a broker, Guillermo can also continue offering some of his high end custom products. To determine if becoming a broker is the best option, Guillermo will evaluate the NPV and WACC for the proposed project. To calculate the NPV, Guillermo must consider the investment time period and the discount rate. In this case, Guillermo will review a period of 20 years. When calculating, the need to remove the income tax from the net profit and then re-add the depreciation back in. Next, consider the value of the company’s equipment. For the purpose of this paper, it will be assumed at $100,000,000 with a straight-lined depreciation of $100,000 yearly, over a 10 year period. Once the ten years is complete, the before tax income will increase for the broker option by $100,000. The cash flow will be reduced by 42% since Guillermo will have to pay the taxes on the increase. Since the building will be completely depreciated after 17 years, the net income before taxes will be $50,000. The net present value for the broker option over the 20 year period at 10% will be $4,125,109. 02.
