Types of Computers Esay

Overview A computer is an electronic device that receives (input) data, processes that data, stores data and produces results (output). Computer can be classified according to their data representation that is functionality, based on their purpose or based on their physical size. It’s the classifications that bring about types of computers.There are four types of computers that is, micro computer, minicomputer, mainframe computer and super computer. 1. 2 Justifications Understanding the types of computers will be helpful in determining whether it’s suitable for the intended purpose. For example if it’s a simple task for an individual or small organization then the microcomputer will be more suitable than a main frame computer which serve large organization. 1. 3 In brief In this essay we define what a computer is in detail in terms of the input, process and output.The features, purposes, functioning, subclasifications and costs of the four types of computers are also discussed. 3. 0 TYPES OF COMPUTERS 2. 1 Defining A Computer According to Saleemi (2009), â€Å"A computer may be defined as a machine which accepts data from an input device performs arithmetical and logical operations in accordance with a predefined program and finally transfers the processed data to an output device. The definition of computer can be viewed broadly in three major cases as illustrated below: Input Process Output Data and instructions Execution and storageInformation â€Å"(All computers can perform the functions of inputting, storing, processing, controlling, styling and outputting data and information (Ravichdndran, 2001 pg2). † It works upon the input data using the issued instructions, this means that the computer cannot do any useful job on its own; hence it’s a clever fool. The term GIGO is also oftenly used to explain this notion that is the computer can only work as per the instructions sets issued, hence if instructions sets conform to t he solving of the problem at hand then it will do it even faster and accurately.But if instructions set do not conform to the solving of the problem then the computer also solves it in the same manner of the instructions set. Hence Garbage in Garbage Out (GIGO). There are varieties of computers with a variety of their operational characteristics. The computer can be classified in many useful ways depending on the objective of whoever is doing the classification. 2. 2 Four types of computers compared The four major categories of computers based on their physical size are micro computers, mini computers, mainframe computers and super computers.These categories are based on the differences in size, speed, processing capabilities and price of computers. Due to rapidly changing technology, the categories cannot be defined precisely. For example the speed used to define a mainframe today may be used to define mini computers next year. Some characteristics may overlap categories still; the y frequently are used and should be understood. Mainframe computers They are most expensive of all computers and very big in size and offer the maximum computing power (Saleemi 2009).They are generally used in large networks of computers with the mainframe being the node point of the network. Smaller computer or terminals are then attached through satellites so that data could be centralized at one place will data processing could be performed via the satellites. A good example is the airline reservation system. The airlines have a mainframe computer at their head office where information of all the flights is stored. Small computers installed at the booking offices are attached to the central data bank so that up to date information of all flights is always available.According to Saleemi (2009) important characteristics include * These are big general purpose computers capable of handling all kinds of problems whether scientific or commercial. * They can accept and transfer data fr om input/output devices at the rate of millions of bytes per second. * They accept all types’ high level languages. * They can support large number of terminals. * Their processing speed is up to several billions of instructions per second. They have a large online secondary storage capability and can support a large number of and variety of peripheral device like magnetic tapes drives, hard disk drives, visual display UNITS, printers and telecommunication terminals. * They usually have high speed cache memory which enables them to process applications faster than mini or micro computer. Mini computers The mini computers are medium sized computers. They are physically bigger than the micro computers but smaller than the mainframe computers.Due to advanced circuit technology some mini computers are almost the size of micro computers. They support average internal and backing storage, that is their storage capacity both internal and external are comparatively higher than the mi cro computers but lower than the main frames (Saleemi 2009). These computers support several users at a time, that is several work stations or terminals are connected to one central minicomputer whose resources (e. g. C. P. U time, storage media, memory etc) are shared among the users connected.If central computers and terminals ate networked (WAN) then telecommunication links are used for a network within the same locality, on the other hand, the cables are used in connecting the terminals and the host computer. The later network configuration is known as local area network (LAN). At the workstation the information is output through the terminal screen or a printer. Sometimes the output can be at the central computer e. g. through a shared printer (usually line printer). Mini computers are used mainly in medium scale business functions. In business they are being used for invoicing stock control, payroll, sales analysis etc.Micro computers According to Saleemi (2009), â€Å"These are computers of advanced technology that become available in late 1970’s. They are the most common form of computers in most offices today as desktop, personal or stand alone systems†. Their design is based on large scale Integrated Circuitry (LSIC) that confines several physical components per small element thumb size I. C (integrated circuit), hence the size dramatically reduced. Their internal memory is smaller than the mini computers and main frame computers. They support limited backing storage media. They are cheaper than the mini and mainframe computers.Where the micro computers are used as terminals, that is connected to the central computer for enhanced processing beyond its capabilities then communication facilities are also to be provided. In small business the micro computers are used in several Min functions that require information to be produced e. g. purchasing, sales, marketing, production, accounting, in word processing for the production of business documents etc. Two popular series of micro computers are the personal computer (PC) and apple Macintosh. Micro computers nowadays come in varied sizes: Desktop computer – Largest and designed to fit entirely on or under a desk or table. * Laptop /notebook computers – second largest and designed such that can be placed on user’s laps. * Palm top computers – smaller and designed so that can be placed on users hand. * PDA (Personal Digital Assistant) – it’s also hand held and provides personal organizer functions such as calendar, appointments etc. Super computers Super computers are the largest, fastest, most expensive computers ever made. They are sometimes referred to as monster computers and have the processing speed of trillion of instructions per second.In many installations super computers are used for limited classes of computations. These computers are often used in numerical application like weather forecast, large matrix calculations such as those required for linear programming to solve problem in economic program or some military statistics. A small number of super computers are built each year for use in applications requiring complex, sophisticated mathematical calculations as in large government research agencies, military defense system, national weather forecast agencies, nuclear energy research, and petroleum exploration etc. 4. CONCLUSION 3. 1 Summary This essay has comprehensively discussed what a computer is in terms of input, process and output. The superiority of the super computers over all the other computers has also been captured. Subclasification of the micro computer thus desktop, laptop, palmtop and personal digital assistant has also been discussed. 3. 2 Insights The development of computers from mainframe to micro computers and super computers is evident from the essay. It’s also worth noting that the advancement of micro computers will continued to diminish the importance of the ma inframe / mini computers. . 3 Recommendations Given that computers facilitate more accurate and faster processing of data developers of computers should invest more in research and development. This will ensure that the computers available in the market for personal or SME use have not only enhanced capabilities but also affordable costs. REFERENCE LIST 1. Saleemi, N. A. (2009).

Effect of Red Bull Energy Drink

International Journal of Sport Nutrition and Exercise Metabolism,? 2007,? 17,? 433-444?  ©? 2007? Human? Kinetics,? Inc. Effect of Red Bull Energy Drink on Repeated Wingate Cycle Performance and Bench-Press Muscle Endurance Scott C. Forbes, Darren G. Candow, Jonathan P. Little, Charlene Magnus, and Philip D. Chilibeck The purpose of this study was to determine the effects of Red Bull energy drink on Wingate cycle performance and muscle endurance.Healthy young adults (N = 15, 11 men, 4 women, 21  ± 5 y old) participated in a crossover study in which they were randomized to supplement with Red Bull (2 mg/kg body mass of caffeine) or isoenergetic, isovolumetric, noncaffeinated placebo, separated by 7 d. Muscle endurance (bench press) was assessed by the maximum number of repetitions over 3 sets (separated by 1-min rest intervals) at an intensity corresponding to 70% of baseline 1-repetition maximum. Three 30-s Wingate cycling tests (load = 0. 075 kp/kg body mass), with 2 min recover y between tests, were used to assess peak and average power output.Red Bull energy drink significantly increased total bench-press repetitions over 3 sets (Red Bull = 34  ± 9 vs. placebo = 32  ± 8, P < 0. 05) but had no effect on Wingate peak or average power (Red Bull = 701  ± 124 W vs. placebo = 700  ± 132 W, Red Bull = 479  ± 74 W vs. placebo = 471  ± 74 W, respectively). Red Bull energy drink significantly increased upper body muscle endurance but had no effect on anaerobic peak or average power during repeated Wingate cycling tests in young healthy adults. Key Words: anaerobic power, caffeine, exercise Red Bull energy drink is purported to improve some aspects of performance (i. . , reaction time, concentration, and alertness) in exercising individuals (1). The primary ergogenic ingredient in Red Bull is caffeine. Acute caffeine ingestion of 2–9 mg/kg body weight during aerobic exercise increases endurance and reduces fatigue (11, 12, 25, 37, 46). Most resear ch on caffeine ingestion has focused primarily on its effects during short-term or extended aerobic exercise (23), with numerous studies supporting an ergogenic effect from caffeine on exercise time to exhaustion (17, 22, 29, 46, 48), maximal power output (32, 37), and performance time (9, 41).The effects of caffeine ingestion on anaerobic performance (i. e. , Wingate cycle power) and muscle endurance Forbes, Little, Magnus, and Chilibeck are with the College of Kinesiology, University of Saskatchewan, Saskatoon, SK, Canada S7N 5B2. Candow is with the Faculty of Kinesiology and Health Studies, University of Regina, Regina, SK, Canada S4S 0A2. ? ? 433 434 Forbes? et? al. (i. e. , total repetitions for lifting a given resistance over multiple sets) are less evident, however. Regarding anaerobic performance, Collump et al. 16) showed that caffeine ingestion (250 mg) 1 h before 100-m freestyle swimming significantly improved performance time. In addition, caffeine ingestion (250 mg) 30 min before exercise resulted in significant improvements during a maximum-power 6-s cycle sprint against various loads (2). Greer et al. (28), however, observed no improvement in maximum force output or reduced fatigue during repeated Wingate anaerobic tests with 6 mg/kg of caffeine 1 h before exercise; Collomp et al. (15) found no improvement during a single 30-s Wingate test with 5 mg/kg of caffeine 60 min before exercise; and Crowe et al. 18) found that 6 mg/kg of caffeine given 90 min before two 60-s cycling bouts had no effect on peak power or work output. Regarding muscle endurance, Kalmar and Cafarelli (35) reported that 6 mg/kg of caffeine given 1 h before exercise significantly increased submaximal isometric-contraction time. In contrast, Beck et al. (7) and Jacobs et al. (34) found no improvement in bench-press or leg-press muscle endurance (i. e. , total repetitions of lifting a weight corresponding to 70–80% one-repetition maximum [1-RM]) 60–90 min after su bjects consumed ~2. 5–4 mg/kg of caffeine.Although it is difficult to compare results across studies, possible explanations for these inconsistent findings might include the dose of caffeine used, subject training status, timing of caffeine ingestion, habitual caffeine consumption, and exercise modality. Although the mechanisms explaining the possible ergogenic effects of caffeine remain to be elucidated, plausible theories include caffeine’s ability to act as an adenosine-receptor antagonist (18, 19, 23), increase plasma epinephrine concentrations (33, 45), enhance calcium release and reuptake from the arcoplasmic reticulum (40), and alter plasma potassium concentrations (18). These mechanisms most likely occur with larger caffeine doses, and it is unclear whether smaller doses would be as effective. Recently it was found that larger doses of caffeine might have negative health consequences such as impaired glucose tolerance (6). We therefore decided to study the effe cts of a smaller dose of caffeine (2 mg/kg) in the form of Red Bull energy drink. To date, only 1 study has examined the effects of Red Bull energy drink on anaerobic exercise performance in young adults.Alford et al. (1) found a significant increase in maximum speed during an all-out cycling test after Red Bull supplementation (80 mg caffeine). Our purpose was to determine the effects of Red Bull energy drink on a more standardized test of anaerobic performance (i. e. , Wingate cycle test) and on muscle endurance (i. e. , maximal repetitions during bench-press lifting). These tests were used to simulate the demands of sports such as ice hockey that involve repeated bursts of activity or muscle endurance of both the lower and upper body.Energy-drink consumption and caffeine supplementation are very common in this type of sport (38). We hypothesized that Red Bull supplementation would increase Wingate anaerobic peak and average power and bench-press muscle endurance. Methods Particip ants Sixteen healthy physically active participants (12 men, 4 women, 24  ± 6 y old) volunteered for the study. They participated in moderate physical activity 2 or 3 Effect? of? Red? Bull? on? Athletic? Performance? ? 435 times per week and were instructed not to change their diets or physical activity patterns before or during the study.All subjects were required to fill out a Physical Activity Readiness Questionnaire, which screens for health problems that might present a risk with performance of physical activity (52). The study was approved by the University of Saskatchewan Biomedical Research Ethics Board for research in human subjects. Participants were informed of the risks and purposes of the study before they gave their written consent. Experimental Design The study used a double-blind repeated-measures crossover counterbalanced design in which participants were randomized to supplement with Red Bull or placebo and receive the opposite treatment 7 d later.All participant s were required to come to the laboratory on 2 occasions before the start of the study, once to determine their bench-press 1-RM strength and again 3 d later for familiarization with the experimental design by performing 3 sets of bench-press repetitions to fatigue (separated by 1-min rest intervals) at an intensity corresponding to 70% 1-RM, followed by three 30-s Wingate cycle tests (separated by 2-min rest intervals) at a load corresponding to 0. 075 kp/kg body mass (4). There was a 10-min rest period between the bench-press endurance tests and Wingate cycle tests.Three days after the familiarization trial, subjects were randomly assigned to supplement with Red Bull (2. 0 mg/kg caffeine) or placebo (noncaffeinated Mountain Dew, lemon juice, water) 60 min before performing repeated-bench-press endurance tests and Wingate cycle tests. Seven days after this initial supplementation and testing session, subjects returned to the laboratory and ingested the opposite supplement drink and performed the same exercises in the same order. They were instructed to refrain from caffeine for 48 h, physical activity for 24 h, and food and drink for 3 h before testing.The 7-d counterbalance was chosen to allow subjects adequate recovery between exercise tests. The 48 h of caffeine withdrawal before testing would be adequate because the half-life of caffeine is about 4–6 h (24). The dependent variables measured were bench-press endurance, peak power during repeated Wingate tests, and average power over 3 Wingate tests. Physical activity level and habitual caffeine consumption were recorded before the study through the questionnaire. The exercise tests were chosen to simulate sports that involve repeated bursts of high-intensity activity, such as ice hockey.For example, the 30-s Wingate tests with 2 min rest between tests simulate the work-to-rest ratio of typical hockey shifts. Time–motion analyses indicate skating times of 30–40 s between rest intervals of either whistle stops or time on the bench. Whistle stops last about 27 s, whereas time on the bench is about 227 s, for an average rest interval of about 2 min (27, 47). The bench-press test simulates upper body work during ice hockey, such as occurs during corner play and occasionally fighting (26).A caffeine-containing supplement is ideal to evaluate for this type of sport because caffeine-containing supplements are the most popular type of supplement ingested by ice hockey players (38). 436 Forbes? et? al. Supplementation Red Bull and the placebo were identical in caloric content, volume, and taste. Supplements were provided to each participant 60 min before exercise in an opaque water bottle and consumed in the presence of a researcher. Sixty minutes was chosen because this is the approximate time it takes for caffeine concentration to reach its peak after oral ingestion (23). The caffeine dose of 2. mg/kg was chosen because it is an approximate amount shown to increase muscl e performance (7) and reduce fatigue in young healthy adults, higher doses might be associated with impaired glucose tolerance (6), it is the maximal daily dose of commercial energy drinks considered safe by Health Canada (30), and this dose allowed our heaviest subjects to consume approximately 2 cans of Red Bull, which is the maximal amount recommended on the Red Bull label. Ingredients in the Red Bull energy drink are shown in Table 1. Muscle Strength and Endurance The procedures for determining bench-press 1-RM have previously been described (13).All bench-press testing was done on a bench-press machine (Lever chest-press machine, Winnipeg, MB, Canada). Reproducibility of our 1-RM test, expressed as a coefficient of variation, was 1. 9% (14). For bench-press muscle endurance, participants performed 3 sets of bench-press repetitions to volitional fatigue, separated by 1-min rest intervals, at an intensity corresponding to 70% 1-RM. Reproducibility of the bench-press endurance tes t was assessed by testing 15 subjects 3 d apart. The coefficient of variation was 1. 5%. Anaerobic Power Peak power and average power were assessed using repeated Wingate cycleergometer tests.Blood lactate concentration was measured at rest, immediately after each Wingate cycle test, and 2 min postexercise using an automated lactate analyzer (Accutrend Lactate, Roche Diagnostics, Mannheim, Germany) according to the manufacturer’s instructions. Ten minutes after the bench-press endurance test, each subject was positioned on the Wingate cycle ergometer, and seat height, handlebar Table 1 Red Bull Energy-Drink Ingredients Ingredient Sugar Caffeine Taurine Glucuronolactone Niacin Pantothenic acid Vitamin B6 Riboflavin Vitamin B12 Amount (per kg body mass) 0. 65 g/kg 2. 0 mg/kg 25 mg/kg 15 mg/kg 0. 45 mg/kg 0. 15 mg/kg 0. 5 mg/kg 0. 04 mg/kg 0. 025  µg/kg Effect? of?

Subjects were instructed to cycle at a slow pace against zero resistance for 5 min. Five seconds before data collection, they were instructed to pedal at maximal rate to ensure optimal power and force production at the beginning of the test and to continue cycling at a maximal speed for the duration of the 30-s test at a load corresponding to 7. 5% of their body mass (4). Subjects were verbally encouraged throughout the test.This procedure was repeated for 3 tests, with 2 min of active rest against zero load between tests. Reproducibility of peak and average power was determined by testing 10 subjects 3 d apart. The coefficients of variation were 4. 1% for peak power and 3. 6% for average power. Statistical Analyses A 2 (caffeine-consuming subjects vs. caffeine-naive subjects) ? 2 (supplement: Red Bull vs. placebo) ? 3 (exercise sets) ANOVA with repeated measures on the last 2 factors was used to assess differences between conditions f or benchpress repetitions and for peak and average power during the Wingate tests. A 2 (caffeine-consuming subjects vs. affeine naive subjects) ? 2 (supplement: Red Bull vs. placebo) ? 5 (blood lactate at 5 time points) ANOVA with repeated measures on the last 2 factors was used to assess changes in blood lactate concentration. To determine whether 1 familiarization trial was adequate to eliminate any effects of learning over time, we ran a 3 (set) ? 2 (time) repeatedmeasures ANOVA to determine whether there were differences across sets for Wingate tests and bench-press tests between the familiarization and placebo trials. Tukey’s post hoc tests were used to determine differences between means. Statistical significance was set at P ? 0. 05.All results are expressed as mean  ± standard deviation. Statistical analyses were carried out using Statistica, version 5. 0 (StatsSoft Inc. , Chicago). Results Of the original 16 subjects who volunteered, 15 completed the study. One mal e subject withdrew because of time constraints. Seven subjects were correct in perceiving that they were ingesting Red Bull or placebo, with the remaining subjects unsure. Before testing, 8 subjects were caffeine naive, 4 reported consuming 200 mg/d. There were no side effects reported from the exercise testing, Red Bull energy drink, or placebo.There were no time main effects or set ? time interactions between the familiarization trial and the placebo trial, indicating that the familiarization trial was adequate to eliminate any learning effects. Subjects who regularly consumed caffeine did not differ from caffeine-naive subjects for any of the tests or for their responses to Red Bull versus placebo (i. e. , there were no group ? supplement interactions). There was a supplement main effect for bench-press endurance, whereby the number of repetitions over the 3 sets was greater in the Red Bull condition than with placebo (Red Bull = 34  ± 9 vs. lacebo = 32  ± 8 repetitions over the 3 sets, P = 0. 031; Figure 1). There was a set main effect for bench-press endurance, Wingate peak power (Figure 2), and Wingate average power (Figure 3); that is, performance dropped across sets as 438 Forbes? et? al. would be expected (P < 0. 05). There were no differences between Red Bull and placebo for performance across sets during the Wingate tests (peak and average power: Red Bull = 701  ± 124 W vs. placebo = 700  ± 132 W and Red Bull = 479  ± 74 W vs. placebo = 471  ± 74 W), and there were no supplement ? et interactions for any of the exercise tests (Figures 2 and 3). There was a time main effect for blood lactate (mmol/L) during repeated Wingate tests (P < 0. 01; baseline: Red Bull: 4. 2  ± 1. 3 vs. placebo 3. 6  ± 1. 0; after test 1: Red Bull 7. 4  ± 2. 4 vs. placebo 6. 6  ± 1. 8; after Test 2: Red Bull 9. 0  ± 2. 9 vs. placebo 8. 9  ± 3. 4; after Test 3: Red Bull 9. 3  ± 4. 2 vs. placebo 8. 1  ± 4. 7; and 2 min postexercise: Red Bull 9. 2  ± 3. 0 vs. placebo 7. 9  ± 2. 4), with no differences between Red Bull and placebo (Figure 4).

Lactate values after Test 2 were similar those after Test 3 and 2 min after Test 3. Discussion This is the first study to investigate the effects of Red Bull energy drink on upper body muscle endurance and anaerobic cycle performance in young adults. Results 440 Forbes? et? al. showed that Red Bull energy drink significantly increased total bench-press repetitions over 3 sets compared with placebo but had no significant effect on peak or average power or blood lactate conce ntration during repeated Wingate cycling tests. The main active ingredient in Red Bull energy drink is caffeine.Although the mechanisms explaining the ergogenic effects of caffeine are not fully known, plausible theories include the antagonism of adenosine receptors (18, 23, 42) leading to an increase in central-nervous-system activation (54) and plasma epinephrine concentrations (45), enhanced calcium release and reuptake from the sarcoplasmic reticulum (40) affecting skeletal-muscle excitation–contraction coupling (42), and the alteration of plasma potassium concentrations (18, 39). Caffeine has been shown to reduce plasma potassium levels compared with placebo during exercise (39).The increased intracellular potassium concentration coupled with lower extracellular potassium might help maintain membrane contractility during exercise (39). Our results of a greater increase in bench-press repetitions over 3 sets from Red Bull ingestion (2. 0 mg/kg), but no single set effect, expand the findings of Beck et al. (7), who found no effect of a caffeine-containing supplement (2. 4 mg/kg) on single-set bench-press repetitions. For the present study, bench-press muscle endurance was assessed by the total number of repetitions over 3 sets at 70% 1-RM separated by 1-min rest intervals.In contrast, participants in the Beck et al. (7) study performed a single set of bench-press repetitions at 80% 1-RM. Differences in supplement composition, study design (crossover vs. cross-sectional), and gender might also explain these different results. In addition, we cannot conclude with certainty that the greater increase in bench-press repetitions from Red Bull energy drink is a result solely of caffeine, because Red Bull contains other ingredients (see Table 1) such as carnitine, B vitamins, and taurine.The effectiveness of carnitine is controversial, with most studies showing no benefit but some showing a benefit for increased fat metabolism and enhanced recovery from exer cise stress (for reviews, see 10 and 36). These ergogenic effects might help during aerobic endurance exercise; however, it is doubtful that a benefit would be provided by acute supplementation before high-intensity exercise. Carnitine supplementation has no effect on high-intensity exercise performance (i. e. five 90-m swims separated by 2-min rest intervals) (53) or metabolic response to high-intensity exercise (i. e. , five 1-min cycle sprints separated by 2-min rest intervals) (5). The B vitamins are important for chronic adaptation to exercise training but most likely would have minimal influence when taken before an acute exercise session (55). Although carnitine and the B vitamins might not be ergogenic for the exercise tests used in the current study, taurine might exhibit beneficial effects.Taurine, a sulfonic amino acid found primarily in skeletal muscle (31, 44), has been shown to increase force production in skinned muscle fibers in a rodent model (3), possibly through i ncreased calcium release from the sarcoplasmic reticulum and increased calcium sensitivity for excitation–contraction coupling. Others have suggested that taurine might exhibit protective effects against cellular stress such as exercise by acting as a free-radical scavenger (49).In humans, taurine supplementation (6 g/d) significantly increased exercise time to exhaustion, VO2max, and maximal workload during cycle-ergometer exercise (56). Nonetheless, the amount of taurine administered before exercise in the current study was relatively low, ranging from 1 to 2 g. Therefore, it is doubtful that it would have significantly affected performance. Effect? of? Red? Bull? on? Athletic? Performance? ? 441 Red Bull energy drink had no effect on anaerobic power measures. These findings support those of Beck et al. 7), who found no effect from a caffeine-containing supplement on peak or average power output in young adults. Although it is unclear why these caffeine-containing supplemen ts had no greater effect on anaerobic power output compared with the findings of others (2, 16), possible explanations might include the caffeine dose used, caffeine habituation, and individual training status. The caffeine dose used in the current study (2. 0 mg/kg) and that of Beck et al. (7) of 2. 4 mg/kg might have been too low to observe an ergogenic effect on anaerobic-power measures.Regarding caffeine habituation, most subjects in the current study were caffeine naive; however, 7 of 15 subjects were caffeine users, with 4 consuming 200 mg caffeine per day. The Red Bull energy drink provided approximately an additional 150 mg caffeine. One previous study suggested that caffeine might not be ergogenic in habitual caffeine consumers as a result of caffeine saturation (50). Several studies have shown, however, that habitual caffeine intake does not affect the ergogenic benefits of caffeine (8, 20, 21, 43, 51).In agreement with these studies, we did not find any differences in res ponse to the Red Bull energy drink between caffeineconsuming subjects and caffeine-naive subjects. Finally, in examining the effects of caffeine ingestion on anaerobic performance in trained and untrained swimmers, Collump et al. (16) observed a decrease in 100-m swim time in the trained swimmers but no effect in the untrained swimmers. We suggest that the variations in subject training status might explain the lack of consistency across studies. Most studies that report positive effects from caffeine on naerobic exercise have used well-trained subjects (16, 20). The results of the current study suggest that moderately active individuals experience no anaerobic benefit from caffeine through Red Bull energy-drink ingestion. In summary, the results of the present study indicate that Red Bull energy drink increases upper body muscle endurance but has no effect on Wingate anaerobic power. Red Bull energy drink is commonly ingested in the hope that it will increase exercise performance. These findings suggest that it might be effective for individuals who perform repeated upper body exercise.Future research is needed to determine whether this increase in upper body muscle endurance will translate into improved performance in sports involving upper body muscle work.

Jonathan Harker and Dracula in his entopic novel Essay

How does Bram stoker manipulate audience response to Jonathan Harker and Dracula in his entopic novel? Since Dracula was written in 1897, by the successful Bram Stoker it has since been a popular novel. The story line is based upon a mysterious vampire in Transylvania who travels to England in the search of fresh blood but complications arise when Jonathan Harker and accomplices intervene, causing a catastrophe. Bram Stoker manipulates his audience’s response to Jonathan Harker and Dracula. The book is set pre-1915 and is of a gothic genre, so is intended to be frightening and mysterious, which are general expectations of a gothic genre. To begin with the first four chapters are written from Jonathan Harker’s point of view, through his journal. Therefore, indicating that Bram stoker wants us to have a good understanding of Jonathan’s character before any other characters are introduced. So that we can get a very clear idea of what he usually like, his habits, what he is like before, during and after going to Transylvania. There are many indications that Bram stoker wants us to view Jonathan as an intellectual, as he focuses on Jonathan’s time spent at the British museum in England, researching for his journey to Transylvania. He wants us to view him as an intellectual so that later on the book you will trust what he is writing about his journey, and not think he has gone mad. Jonathan also comes across as a very precise man as he notes the exact train times down, â€Å"should have arrived at 6:46, but the train was an hour late. † Bram stoker also puts this across later in the chapter when other times are mentioned. By putting the exact time it emphasises how precise he is. He wants us to see Jonathan this way so that the audience think he is a trustable character, and believe what he is saying. Bram Stoker also portrays Jonathan as a very observant character. This can be deduced from the notes in Jonathan’s journal, â€Å"a country which is full of beauty of every kind,† showing he is interested in his surroundings, and other cultures. Therefore, we see him as an open-minded man; Bram Stoker is portraying him like this because he wants us to see Jonathan as a very good character in the book, he is trying to build up a very positive image of him so that the audience will trust his judgement. We first encounter Dracula when he sends a letter to Jonathan, the letter finishes with, â€Å"your friend, Dracula. † Suggesting that he is either been watching him, maybe they have had previous acquaintances or he is trying to get on Jonathan’s good side. So it shows that Dracula is quite cunning and Bram Stoker is starting to show that Dracula is quite devious and can be quite sly, he does things for a reason. Bram stoker also portrays Dracula as a possessive character, as in the letter he refers to Transylvania as â€Å"my precious land. The word â€Å"my† suggests that Dracula counts the country as his own and in a way he is in control, or he could just be very proud of his country. So by doing this Bram Stoker is showing Dracula as an even more possessive person, but he is also showing that he is powerful character, he’s trying to show Dracula as a bad character in the story. As the chapter continues, Bram Stoker portrays Dracula as an evil character when Jonathan first meets him in person. Bram Stoker uses effective adjectives to create a frightening scene, â€Å"Throwing long quivering shadows. † The adjective â€Å"quivering† suggests everything, even the shadows, live in fear of the evil Dracula. So Bram Stoker is trying to get the audience to believe he is a very powerful and fearful character. Bram Stoker would also like us to see Dracula as an intellectual as in Jonathan Harker’s journal he says, â€Å"Saying in excellent English. † The word â€Å"excellent† emphasises the fact that Draculas English is good, so Bram Stoker makes a strong point of the audience seeing him as an intellectual. We respond to his by thinking he must have Jonathan Harker at his castle for a reason, but why? This creates suspension and keeps the reader interested. We then meet Jonathan Harker later on in the book when Mina describes him in her journal and letters to Lucy Westenra. Thus, we learn about him from others whose opinion we respect. Mina refers to Jonathan quite frequently in her letters and journal. This shows Bram Stoker wants us to see him as someone that people look up to, ad strive to be like him. â€Å"I want to keep up with Jonathan’s studies†; â€Å"I shall be able to be useful to Jonathan. † These phrases from Mina show that she looks him as an example, so therefore showing the audience that he is a very important figure in people’s lives. This makes us think of Jonathan as the good character, the hero in the story and I think people expect a lot of him. Through Mina’s journal, Bram Stoker presents Jonathan as a man that keeps his word, â€Å"I had not heard from Jonathan for some time. † It suggests that he normally writes to Mina whilst he’s away, and so it was unusual for him to not write, he is trying to get us to see that Jonathan is usually a man of his word and sticks to what he does, in this case, keeping contact with Mina. We respond to this by believing that Jonathan is a trustworthy character, adding to the fact that we think he will come out as the hero in the novel. Bram Stoker wants us to see Jonathan as a hard working individual, because then we know that he is going to apply his determination to something, but the audience doesn’t know what, so it s building up the story. In Mina’s journal it states, â€Å"Rich, master of his own business. â€Å"The phrase suggests that to be rich and successful he must be hard working and determined. Further on in the book, after Jonathan has returned from Transylvania, Bram Stoker shows that Jonathan isn’t fearless, â€Å"I noticed that the others kept looking over their shoulders as every sound and every new shadow, just as I felt myself doing. † The quotation suggests that he feels uneasy in his surroundings and that he has a fear of something, so Bram Stoker portrays him as not fearless, unlike at the beginning of the book, where he is presented as fearless and a very successful. I think by showing a change in the character Bram Stoker is implying that the circumstances have had an effect on him and that they must have been awful circumstances because to begin with he was a fearless man and now he’s looking over his shoulder, scared of his surroundings. Dracula is then described in Mina Harker’s journal, during which he is in the form of a dog. â€Å"Long and dark with red eyes. † This is a description of the glance that Mina caught of Dracula. The adjective â€Å"red† suggests evil, so Bram Stoker is building up to the fact that Dracula is the evil character in the book. Bram Stoker only describes Dracula thoroughly through Jonathan Harker’s journal at the beginning of the book, I think that this is because he doesn’t want to give too much away, just give little hints throughout the book and also he mainly does it through Jonathan’s journal because the audience can trust what he is saying is true.

Storytelling Reflection Essay Example | Topics and Well Written Essays - 250 words

Storytelling Reflection - Essay Example He used a hurriedly set up apparatus to experiment ether on a patient. Subsequently, the novel technique was used to revolutionize the practices of surgeons (Relief of Pain and Suffering, 2). I think it is intriguing to find out the true stories behind medicine and how they came about, leave alone the discovery itself, but also the experimental results of such discoveries. Most of the conclusions of medical researchers are highly exaggerated and misleading. This makes it imperative to do an in-depth research into the real discoveries and experiments that led to the commercialization of a given medicine, for this instance, anesthesia. Personal judgment is more reliable that a misleading medical researchers conclusion (The Atlantic, 2). My initial process of preparing involved research on the intended topic. Background research involved Horace Wells and William Morton, who co-discovered anesthesia. The core research on the topic was on the Anesthesia experiments performed by the two ancient dentists. Listeners responded to my story with other stories, on the tacit part they knew, which led to a better understanding (Sharing Knowledge, 3). Story telling played a key role in sharing knowledge and boosted the learning and hearing likelihoods. Through the use of questions that are provocative, listeners got to give their honest experiences with the Anesthesia. Participants from diverse backgrounds teamed up to create an interesting dynamics (Sharing Knowledge,

Taxonomy of Learning Research Paper Example | Topics and Well Written Essays - 1250 words

Taxonomy of Learning - Research Paper Example Benjamin as a committee chairperson, wanted to improve the level of understanding in students so as to deepen their understanding of the subject matter. Anderson has various believes in relation to excellence in a real life situation. Anderson’s argument and interpretation on intelligence of excellence is based on the Triarchic Theory on Intelligence. This theory entails three types of knowledge sub-sections that are; creative, analytical and practical knowledge and skills. All these sub-section of intelligence, have their basic roles to play. Creative part of the intelligence offers or creates room for acquiring and learning new things. This enables one to venture into various activities that need a lot of understanding and wise decisions. The analytical part of intelligence is used in planning, monitoring and evaluating the performance level of different tasks. This makes one to arrive at wise and ideal decisions that can help in making or enhancing academic success. Practic al sub-section of intelligence is used in performing to various tasks. This gives one the potentiality to apprehend positively to their duties and responsibilities. Generally, intelligence can be linked to education in which all the qualities and sub-sections of intelligence are needed for a student to successfully accomplish their set goals and objectives in life. The goal of education is always based on promoting high level of thinking and the ability to interpret information. Education in this case should always major on individual strengths as they think or find more ideal or genuine ways of curbing their weaknesses through the implication of all the three sub-sections of intelligence. Some bits of efforts to enhance the successful implementation process successfully should also accompany the three sub-sections of intelligence. Intelligence as a basic factor of education should be handled with a lot of care. This cannot be handled physically but by the kind of actions involved i n the school management system (National Association of Secondary School Principals, 2007). Learning institutions should also provide a conducive environment that can support the learning process so as to favor the comfort of scholars. This can really contribute in boosting the performance level of various institutions. There are also some of the things a part from intelligence instillation that various scholars and principals should know as far as the learning process is concerned. All the learning facilities should be availed to scholars so as to enable them have good reference and practical items that can enable them to understand their various subjects of study. Though the curriculum involved in the education systems of various institution in the world are effective There are still some little problems that tend to interfere with the whole thing. Some of these things are mainly centered on the quality of services received by the scholars. The school management system should ensu re that all its staff members perform their duties and responsibilities to perfection. On the other hand, scholars are also supposed to apprehend positively to some of the rules and regulations of the school (Woollaccot, 2009). The strategic position of the school should also be considered so as to enhance a conducive position that can support learning process. The school or learning institution should be position or built in places free from excess noise

Create a value chain for Ryanair. Examine the extent to which Ryanairs Essay

Create a value chain for Ryanair. Examine the extent to which Ryanairs value chain represents a traditional value chain, as opposed to a revised value chain, - Essay Example These core competencies help in the creation of value chain. Porter’s traditional value chain focuses on the enterprise and its internal mechanisms and is recognized as an effective management tool for value analysis. This paper will examine how this traditional value chain differs from the revised value chain created by Deise et al., and create a value chain for Ryanair based on its core competencies. According to Porter, ‘every firm is a collection of activities that are performed to design, produce, market, deliver and support its product. All these activities can be represented using a value chain’. The porter’s model of value chain (Table I) describes generic activities undertaken by the firm to procure, transform and add value to the products and services delivered to the customer. These activities can be primary or support activities where the primary activities are concerned with the transformation of the input into output as services or after sales service. Support activities include procurement, HRM, technology and infrastructure. A firm’s value chain reflects its history, strategy, the approach to implementing the strategy and the economics of the activities themselves. In this traditional value chain each activity is an independent process and each activity sequentially adds value to the final outcome. Creating a value chain is with the objective to create a process or product that will lead to profits. Thus value chain analysis studies each link of the chain to ensure that economic value is added to it. According to Porter, adding value is a strategic means to achieve profit and competitive advantage. Traditionally different business functions perceived and created value differently but with Porter’s model each activity can be analyzed individually or collectively to asses their contribution to the enterprise. An analysis helps to eliminate the inefficient processes and add value. Mascarenhas, Kesavan and

Why is the notion of identity so important for the Constructivist Essay

Why is the notion of identity so important for the Constructivist approach - Essay Example Constructivist approach maintains central place in the disciplines including teaching and education, sociology and economics, and philosophy and psychology. However, it has obtained imperative significance in history, international relations and political science too due to its validity and vastness in respect of defining and encompassing the developments being observed at national and international scales by depicting the motifs and intentions behind the entire scenario of rabidly developing world at large. First articulated by the contemporary era American political scientist and theorist Nicholas Greenwood Onuf, the Constructivist approach submits to state that human actions appear to be the most dynamic factors of all progresses being observed in all parts of the world without discrimination. Consequently, it is human actions that give birth to social and political changes in accordance with the events taking place at international arena. These events and incidents appear to be r eliant upon one another in a sense that one event may give way to the others making a chain of developments subsequently (Onuf, 1989, p.49). For instance, it was the strict German political scheme against the vanquished France in the aftermath of the Franco-Prussian War of 1870-71, which had given a go to the establishment of several international alliances including the Dreikaiserabund (or Three Emperors League), Triple Entete, Triple Alliance and others from 1875 to 1912. Similarly, the Treaty of Versailles (1919) drafted by the then British and French prime ministers i.e. Lloyd George and Clemenceau respectively in the aftermath of WWI, certainly contained the seeds and elements of another horrible war for the future years to come (Lowe, 1996, p.238). Moreover, the active participation of America in the Russ-Afghan conflict (1979-89) not only led the circumstances towards the disintegration of Russia, but also

LLM Human Rights -Case study on prosectution Case

LLM Human Rights - on prosectution - Case Study Example During his reign he did a lot of inhuman atrocities against them on the pretext of their opposing his regime or for supporting Iran in the war. After the fall of Bagdad most of his lieutenants were captured but Saddam remained at large and was ultimately captured on the night of 12th December 2003. ' After the initial annexation of Iraq, it was ruled by the Coalition Provisional Authority (CPA), which was later on replaced by an interim government of Iraq. CPA created Supreme Iraqi criminal Tribunal (SICT), for the trial of the Saddam and other members of the Baath Party against charges of committing war crimes and other crimes against humanity. SICT held trials in front of five judges who heard both the sides and dispensed judgment and in doing so there was no provision of jury, there was also a chamber for further appeals consisting of nine judges.'The first trial of the tribunal began on 19th of October 2005, with the case of Dujail massacres of 1982, for which Saddam and seven others were tried.' Although one of the lesser crimes of Saddam, considering his standards, Dujails was probably taken up before the more serious Al-Anfal massacres because Anfal was much bigger in proportion and hence was expected to take much more time. Dujail is a Shitte town, having among its residents many supporters of the Dawa party, which was opposed to Saddam's rule. On 8th of July 1982, Saddam had gone to the town to praise those Shia's who were fighting the Iran - Iraq war on his behalf. Idea was to get more support from the large Shia community to fight the war against Iran. As he was returning from Dujail, his motorcade was fired on by a member of the Dawa party. Although Saddam was not hurt, he decided on a general retaliation. In the events that followed, his security forces killed nearly 150 civilians of Dujail and many were severly tortured. Also a large number of residents including women, children and the aged were send to the concentration camps. During the trial, one of the victims , who was 15 years old at the time of the massacre testified about the genocide. (McGeough, 2005) Based on this case along with Saddam, Barzan Hassan, former Iraqi intelligence chief, and Awad Bandar, former head of Iraq's Revolutionary Court, and Taha Yassin Ramadan, the former vice-president were also ordered to be executed, for participating in crimes against humanity. The more serious anti-Kurdish "Anfal" operation was carried out between February and September 1988 by Saddam Hussein. It was conducted in eight stages, with about 2, 00,000 ground troops bolstered by air support. Its primary purpose was to wipe out any Iranian intrusion in the region and also to put to rest the dream of Kurdish independence. The main targets of this campaign were the battle worthy adults and young men. Saddam wanted to exterminate them all, so that no one should be left to take up arms against his regime. It was conducted under Saddam's cousin, Ali Hassan al-Majidin, who was appointed in charge of the Northern region of Iraq, in March 1987. ' During these campaigns men (above the age of 15) were set apart from the women, later these men were killed and their bodies were dumped in mass graves.' Some of the sites, later excavated were found to have the bodies of thousands of victims. According to liberal estimates some fifty thousand Kurds died in these attacks, while the actual figure is supposed

The Christiana UPS building Essay Example | Topics and Well Written Essays - 250 words

The Christiana UPS building - Essay Example The problem with UPS Christiana building is that the amount of work they handle has increased, hence, expansion is the only end to this congestion. Implementing the proposed solution will not require additional invention. UPS Christiana only needs to assign available constructors to use already existing tools, equipments, and materials to complete the expansion. I doubt the feasibility of this plan since implementation depends solely on the availability of land that the author does not assure us of. The executive summary is not concise and accurate because it does not give an exact explanation of how a large building will lead to faster arrival of customer packages. Additionally, using unclear phrases such as â€Å"our competition is designing new systems and technologies to compete with us† makes the executive summary to lose accuracy and ability to engage the reader. The summary discusses all parts of the assignment, but the information given in some parts is irrelevant. Considering several flaws in the executive summary, I would not read the business plan as an executive because I would expect it to be a piece of bori ng text. When writing an executive summary, the author should remember that they are writing to people with busy schedules who need accurate information that is specific and relevant to the problem that the business planners intend to

Trust in a law Case Study Example | Topics and Well Written Essays - 2000 words

Trust in a law - Case Study Example Since ex hypothesi the transfer is on trust, the resulting trust does not establish the trust but merely carries back to A the beneficial interest that has not been disposed of. Such resulting trusts may be called "automatic resulting trusts". It is further noted that Arnold paid for the loan amortization until his death in 2001. Thereafter Wendy invited Bill in writing to live with her stating that the letter had interests in the house as well. In this situation Wendy's action of writing a letter to Bill inviting him to move in with her and further stating that Bill had an interest in the aforesaid property created an express trust or by implication an implied truest. As a result of this, Bill paid the loan amortization installments amount equivalent to 25% of the original purchase price. Contrary to the original perception that Bill is not an actual party to the ownership of the freehold house bought by Arnold and Wendy who had in truth and in fact had joint ownership the turn of events because of Wendy's action of writing made Bill an owner also. ___________________________________ 3 Vandervell's Trusts (No. 2) (1974) ch. 269,; Megarry & Wade: The Law of Real Property (6th Edition) Serapio 3 According to the law, a trust can be created through a written document known as an express trust or can be created by implication known as an implied trust. Normally, a trust can be created by any one of the following to wit: (a) A written document created by the settler and signed by both the settler and the trustees, this is often referred to as an inter vivos or "living trust"; (b) an oral declaration; (c) the will of a decedent, usually called a testamentary trust; or (d) a court order. In this instant case there exists two... is. Such resulting trusts may be called "presumed resulting trusts."; (b) The second class of case is where the transfer of B is made o trusts which leave some or all of the beneficial interest undisposed of. Here B automatically holds on resulting trust for A to the extent that the beneficial interest has presumptions, but is the automatic consequence of A's failure to dispose of what is vested in him. Since ex hypothesi the transfer is on trust, the resulting trust does not establish the trust but merely carries back to A the beneficial interest that has not been disposed of. Such resulting trusts may be called "automatic resulting trusts". with her and further stating that Bill had an interest in the aforesaid property created an express trust or by implication an implied truest.

A Unique Man Essay Example for Free

A Unique Man Essay The novel Into the Wild, written by author Jon Krakauer, takes place in the western portion of the United States during the late 1980s, early 1990s. Chris McCandless grew up in Washington D.C. and attended college at Emory University. He did not live an ordinary life by choice. He abandoned his opportunities after graduation and decided to travel out west for his own enjoyment and self-discovery. Chris McCandless is very different from an ordinary person because he explores life to the fullest and does not believe in society’s perception of what a person’s life should be. Chris McCandless did not need materialistic items to make his life more enjoyable; he only needed Mother Nature and his own motivation. For example, Chris does not want a new or better car because he is perfectly content with the Datsun, an old car passed down to him by his parents. His parents wanted to buy him a new car; however, he disagreed and became upset at the idea of having a new car in his possession. Chris’s perspective on the situation is that the Datsun is still in very good condition, therefore there is no reason to replace it with a more advanced car. Additionally, Chris donates over $24,000 to Oxfam International, a poverty eradication charity. The money that he donated to Oxfam International was originally given to him by his parents. However, Chris believed that this money was just a distraction and in order to make a point that he did not need the extra money and that he was satisfied with his life, he decided to donate it. Furthermore, before Chris began his adventurous journey for Alaska, he burned the rest of his money that he owned into ashes. He thought that money was just a distraction for what you could accomplish. One thing that Chris realized was that in life money is not everything, and happiness and tranquility cannot always be bought. The same thing goes for materialistic objects which are considered a distraction and unnecessary in the overall vision of the ideal life. In conclusion, Chris never needed materials or money to feel happy; he just needed motivation, nature, and the wild. Chris McCandless was always viewed differently by others since he lived an unordinary lifestyle. He would explain his theories and view of life to many others during his adventure to Alaska. For example, Wayne Westerberg, the first man to encounter McCandless on his vigorous adventure. Chris wasn’t prepared for the wild with the supplies he had, Westerberg helped him out with more advanced supplies. Chris shared his story with Wayne and they talked about their views on the lifestyle. Chris gave his input, but Wayne thought he was wild and out of his mind, but he liked Chris. Additionally, Chris encountered Jan Burres. Chris told Jan about his goals that he set for Alaska and the long adventure. At first Jan did not have must interest in of the matter. Then she gave her own insight on the hardships he would face and what he would need. Jan told Chris that he would have to acquire a job and shelter. Also, she said Chris would need plenty of food and water to prevent starvation during his traveling. Furthermore, Ron Franz was an old man Chris came across on his endeavor for Alaska. McCandless told his story towards his perspective on societies thoughts on what life should consist of. Franz thought he had interesting points and was a clever young man. Chris even convinced Franz to climb a mountain at one point to see a great view Chris had found. Chris encouraged Franz to take a risk and leave his everyday lifestyle and had him climb a steep mountain. In conclusion, Chris was an inspiration to many other people with his unordinary perspectives on the valuable things you occur in life. Chris McCandless would rather risk his life for his thrill of the adventure and nature than play it safe and be like everyone else. For example, McCandless has a main goal of traveling all the way to Alaska by foot. Chris did have a vehicle, the Datsun, but he abandoned the car and continued his quest for Alaska. On his way to Alaska he is offered help, such as food and shelter, and sometimes he would reject the help and continue on. He had the knowledge and skills to build his own shelter and obtain his own food. Also, he does not want or need valuables or materials to be satisfied. One example of this is the action of Chris donating over twenty thousand dollars to an organization. Another example is when Chris burns the remaining money he has left. Soon after he burns his money he abandons his longtime car, the Datsun. Furthermore, Chris prepares vigorously for hardships he could be unaware about of the wilderness. He would read multiple books as some preparation for the vigorous adventure from the United States to Alaska. He also gathered advice from multiple people he met during his traveling and took what people said into consideration. Chris possessed a guide that told him about different kinds of plants and if they were poisonous or not. In conclusion, Chris likes the idea of adventure, the challenges he will face, and the beauty of nature. Chris McCandless does what he believes life should consist of instead of accepting society’s view of what the normal life is. I think Chris succeeded in trying to live a transcendental lifestyle. He took on a grueling challenge that not many people would even consider. Even though he died on his adventure to Alaska, he was probably one of the bravest men to ever live. Also, Chris’ arrogance was not an obstacle to his success in achieving his goals, it was a confidence boost. His arrogance was a sign of confidence and knowledge, unfortunately he didn’t make it to Alaska. In conclusion, Chris succeeded in being what he viewed as a man and this brave man died trying to achieve a very unique thing.

Discuss The Communication Process And Its Elements English Language Essay

Discuss The Communication Process And Its Elements English Language Essay This essay will discuss the communication process and the elements it consists of. I will then critically applying these theories to my own case study, that will be discussed in more detail at a later stage, and relate it back to the various elements of the communication process. The Communication Process The word communication originated from the Latin verb communicare. The meaning of this words translation (which is to share or to make common) provides the first half of the meaning of the English word communication. The second half is related to information and meaning. (Coates, G.T. 2009. Notes on Communication: A few thoughts about the way we interact with the people we meet. Definitions of Communication. Free e-book from www.wanterfall.com. 13) So, ultimately, communication simply means to share or make ones meanings or information in ones possession common? Unfortunately it isnt that easy. Almost every author of a publication regarding the science of communication assigns a different definition to the concept of communication. In the following definitions its quite clear that information is more often incorporated into these definitions than meaning. Its also clear that an interaction that seems to be simple is actually quite complex when investigated. A few definitions include: Communication is the sharing, giving and receiving of information Communication is the transfer of information from one or more people to one or more people (Coates, G.T. 2009. Notes on Communication: A few thoughts about the way we interact with the people we meet. Definitions of Communication. Free e-book from www.wanterfall.com. 13) Communication is the symbolic process of sharing meanings (Galvin, K.M. Wilkinson, C.A. 2006. The Communication Process: Impersonal and Interpersonal. The Communication Process. Roxbury Publishing. 5) Communicationà ¢Ã¢â€š ¬Ã‚ ¦(is) the transmission of a message from a sender to a receiver in an understandable manner (Sanchez, N. Communication Process. And according to Dr Appalayya Meesala for the transfer of the information, a certain vehicle (medium) is assigned, which loads itself with the message and passes it on to the intended receiver(s). The way the mediums transport the information in such a way that the receiver understands it as its intended to, is the communication process (Meesala, Dr A. Understanding the Communication Process The Key to Organisational Success. Meaning Meanings greatest limitation is that even though it is present in ones mind at all times, it is never fully. The meaning received by the by the individual on the receiving end of the communication is hardly ever the same as the meaning intended by the sender. This is because of their uniqueness regarding their individuality, sensory organs and cognitive functions. Various factors can influence the accurate transfer of the intended meaning from the sender to the receiver. These include: Word or phrase usage, the register of language, the structure of sentences, the individual characteristics of each communicator, the non-verbal messages sent, the pre-existing knowledge each communicator possesses of the other, the relationship between the communicators, method used to deliver the message, the audience and the surrounding events or interference. These influential factors are also referred to as the context in which the message is transferred. It is thus easy to conclude that the accurate transferral of ones meaning to a receiver(s) is a science as well as an art. (Coates, G.T. 2009. Notes on Communication: A few thoughts about the way we interact with the people we meet. Definitions of Communication. Free e-book from www.wanterfall.com. 14-16) Even more, although the use of verbal and non-verbal codes allow us to transmit thoughts and emotions, the mediums used in a communicative interaction should be mutually understood by both communicating parties for meanings to be more accurately shared. Common meanings make it possible to communicate. And communication mishaps occur due to missed meanings (Galvin, K.M. Wilkinson, C.A. 2006. The Communication Process: Impersonal and Interpersonal. The Communication Process. Roxbury Publishing. 7). Sending and receiving Messages One would usually use the word channels to describe how messages are sent and received but so many experts assigned completely different meanings to this concept. Thus I will use Dr Gordon Coatess choice of words i.e. Instead, I will simply say that messages passed between two people need a way to get out of one person and a way to get in to another person. Therefore, I will talk about output and input (Coates, G.T. 2009. Notes on Communication: A few thoughts about the way we interact with the people we meet. Definitions of Communication. Free e-book from www.wanterfall.com. 18). By output I will refer to information going out from sender to receiver and, thus, input will refer to that information being received by the receiving party. The input system is sometimes wrongly confused to be a passive process and the output process is an active process. Regarding the human brain, taking in information is indeed an active process as well. Inputs are achieved by means of sensations and outputs by means of actions. With that said, when referring to sensations I mean signals received by ones sensory organs, then transferred to ones brains via nerve fibres and then processed. Organs that are particularly involved in this process are the eyes, ears and tactile sensory systems (their importance follow in that very order too.) (Coates, G.T. 2009. Notes on Communication: A few thoughts about the way we interact with the people we meet. Definitions of Communication. Free e-book from www.wanterfall.com. 18-19) Various people seem to use one of these three organs more effectively than the others. Although a preference towards using one doesnt exclude using the other, it does reduce the effectiveness to which the others are used. And when two interacting communicators dont share a mutual preference towards a certain input, communication mishaps may occur when it comes to understanding meaning. Outputs are achieved by means of specific actions like talking, writing or physical gestures. They are also named after the input used to receive them i.e. visual, auditory and tactile. For example, when a gesture is made, a visual output is employed. Other than inputs, the actions used to achieve outputs are performed by body parts and NOT by the sensory organs. Thus inputs and outputs use different parts of the body. (Coates, G.T. 2009. Notes on Communication: A few thoughts about the way we interact with the people we meet. Definitions of Communication. Free e-book from www.wanterfall.com. 22) Verbal and Non-Verbal Communication Verbal communication refers to written as well as spoken words used to communicate as it means using a language to share information. (Coates, G.T. 2009. Notes on Communication: A few thoughts about the way we interact with the people we meet. Definitions of Communication. Free e-book from www.wanterfall.com. 39) Non-Verbal communication gets most of the attention in most publications regarding communication science. Non-verbal communication refers to any communication that is achieved without solely relying on the use of words or symbols to transfer information. This type of communication may even provide more information than the spoken words used during interactions and provide all this additional information simultaneous to the spoken words. (Coates, G.T. 2009. Notes on Communication: A few thoughts about the way we interact with the people we meet. Definitions of Communication. Free e-book from www.wanterfall.com. 48) Aspects of non-verbal communication include: First Impressions, Distance, Orientation, Posture, Movements, Gestures, Facial expressions, Eye contact, Sound effects, Direct contact, Consent issues and Personal qualities. Components of the communication Process Case study To effectively explain the components, or elements, of the communication process I will apply them to a case study, thus a realistic experience. The interaction I have chosen is a conversation with a friend via the widely popular social network called MXit. I have chosen this case study because I think it represents each component in the communication process quite clearly and accurately. The elements I will discuss on the basis of this case study are: Communicators (sender and receiver), Message, Noise, Feedback and the Setting/Context. These elements are not mutually exclusive but they are indeed considerably interlaced/interdependent. During the communication process the sender and receiver (the communicators) switch in the roles they play, but everything else stays the same. Thus the direction of information changes but the process itself stays unchanged. The sender is also known as the source or the initiator of the communication process. (Nordquist, R. Communication Process. http://grammar.about.com/od/c/g/Communication-Process.htm?p=1. 2011. 1) He is faced with the first step which involves the encoding or translating of a cognitive idea or information onto understandable words and using the appropriate medium to transfer this message in such a way that the receiver will understand it. It is of immense importance that the sender uses mediums that are mutually familiar between him and the receiver. A good thing to keep in mind is the saying say what you mean and mean what you say. In my case study I was the sender who initiated the conversation by greeting my friend and thus sending the first message using a mutually understood language. The receiver is the other person involved in this interaction who decodes the message sent by the sender, thus my friend on the other end of the waves transferring our messages from and to each other. The receiver must be sufficiently accessible to receive the message (Coates, G.T. 2009. Notes on Communication: A few thoughts about the way we interact with the people we meet. Definitions of Communication. Free e-book from www.wanterfall.com. 152). In the case of my MXit conversation, for a fluent conversation to take place my friend must be in an area with sufficient signal. This communicator must also possess and employ both sensory capacity (good eye-sight to be able to read my messages coming through and that are displayed on his cell phones screen) and cognitive capacity (be bright and mentally clear in order to understand my sent messages and intended meanings). All the receivers interpretations of the senders message are influenced by his experiences, attitudes, knowledge, ski lls, perceptions and culture. The same aspects influence the senders encoding process (Sanchez, N. Communication Process. http://web.njit.edu/~lipuma/352comproc/comproc.htm. 2000. 2) The message is the encoded thoughts of the sender taking the form of the chosen code. It is the essential content of information to be passed in communication (Meesala, Dr A. Understanding the Communication Process The Key to Organisational Success. http://ezinearticles.com/?Understanding-the-Communication-ProcessThe-Key-to-Organisational-Successid=876670. 2007. 2). It can be written, verbal or non-verbal, pictures, diagrams or numbers and should be in the language mutually understood my both sender and receiver. Messages usually have hidden or clear meanings that the receiver has to unravel in order to understand the message the sender is trying to convey. Seeing as textual social networks mainly rely on eye-sight as means of input and output only, non-verbal messages accompanying the verbal messages cant be observed and so misunderstandings in the effect of the messages can occur. Thus my friend and I have to carefully choose the wording of our messages to avoid uncomfortable mishaps. Noise refers to any distraction or interference in the environment in which the communication is taking place and can be physical or psychological (Johns, T. 1995. Business Basics: Organisational behaviours. The Communication Process. BPP Publishing Limited. 9) Noise can also refer to a problem in the chosen medium or encoding or decoding of the message in some stage of the process that can lead to misunderstandings (Meesala, Dr A. Understanding the Communication Process The Key to Organisational Success. http://ezinearticles.com/?Understanding-the-Communication-ProcessThe-Key-to-Organisational-Successid=876670. 2007. 2) In my case study the MXit service was unstable and either me or my friends phone will occasionally disconnect from the service temporarily and so messages will get lost and wont be received by the intended receiver. This caused frustration as the receiver will keep waiting ignorant to the fact that the message got lost in a bad connection and will start thinking the sender is ignoring him. This just creates an uncomfortable atmosphere that can influence the fluid continuation of the conversation. Feedback is the final step in the communication process. This is when the role of the sender and receiver swaps and its the receivers turn to send a message which will be a response to the senders message he decoded. This is of immense importance as this is an evaluation of the senders communication abilities. The efficiency of the senders ability to communicate will be determined by the receivers reaction which will determine whether the senders meaning was effectively transferred or not. In my case study feedback will be any response to any message sent between my friend and I. These responses determined whether we have the same meaning assigned to some of the slang and abbreviations we used and enable us to apply changes in our encoding where needed. Context in the communication process refers to the idea that there is a suitable time and place for every message that needs to be conveyed. There is physical context (the environments one chooses to communicate in), social context (the occasion during which one chooses to communicate in) and cultural context that involves an even bigger set of rules in certain societies which will restrict the way you communicate (Dimbleby, R. Burton, G. 1998. More Than Words: An Introduction to Communication, 3rd ed. Routledge) In my MXit conversation the context refers to the context of each individual communicator. For instance, it would be rude to chat on MXt while one is sitting at the dinner table or having a personal conversation with another person. To converse in a MXit conversation one has to be at ease and alone in the comfort of ones privacy and not be interacting with other people. Conclusion Thus I just proved Dr Gordon Coatess statement correct. Through investigating and discussing the components and elements of the communication process in more depth and then applying the theory to reality, it is clear that although it seemsà ¢Ã¢â€š ¬Ã‚ ¦ that the process by which communication occurs is very simple in concept, (it) can become extremely complex if it is inspected closely.

History of the Lambada and Its Relationship With World Music

History of the Lambada and Its Relationship With World Music Lambada History is very interesting, because it is composed of many stories and it is quite difficult to hear one and the same story of Lambada. But doubtless remains the fact that the Lambada is one of the most famous and popular Latin dances, which are known and are dancing around the world. The word Lambada refers to the rhythm (a mixture of karimbo and merengue) and dance that combines elements of Forry (forrà ³), samba, merengue and maxixe (Brazilian dance of the nineteenth century), which had huge success in Europe. Lambada became the most popular dance in 1989 and early 1990s. This fiery dance which was born in Latin America, ruled the entire planet, and in Europe it sold over two million records with Lambada music. People were amazed with this music that reminded the rustle of palm trees, the lapping of the warm ocean, singing of birds. Thats why in the early 90s almost every day on American and European television was shown video of Lambada dancing by professional South American dancers. That was true musical performance video, which was kind of a dance school, and opened a whole world of Latin American culture. Europeans and Americans took Lambada with enthusiasm, they admired the fiery and the brightness of Hispanics, and soon Lambada was dancing in the whole E urope and America. The history of Lambada and its relationship with the world music The origins of Lambada dance came from karimbo at the time when Brazil was a Portuguese colony (1500-1822 gg.) in the northern part of the country there was a popular dance called karimbo, that was very sensual dance of man and woman. Over time the dance has changed, and changed the music: because of the proximity to the Caribbean region, the Caribbean music culture had a strong influence on Brazilian music (even today we can feel it if you listen to Caribbean radio station in the northern states of Brazil). This close relationship gave birth to some new rhythms Sirimbà ³ and Lari Lari; so karimbo dance eventually changed so much that gave birth to practically new one. After some time the local radio station Belà ©m (capital of Parà ¡) began to call this new kind of music percussion rhythm and the rhythms of Lambada (the word Lambada means a strong rhythmic beats of music). This last name Lambada became very popular and became associated with the new image of the old dance style . Later people again began to dance karimbo in pairs, and it was very much like merengue, but had a larger number of spinning. In the end, a mixture of metal and electronic music of the Caribbean once again changed the face of karimbo, and the music quickly spread throughout the northeastern region of Brazil (the most touristic places), only this new karimbo was already called Lambada. Lambada long traveled along the coast, and finally reached Bahia (the oldest of the Brazilian state), where it began to experience the effect of dance Forry (another old Brazilian style with the accented rhythm). Gradually, the timing of Lambada from a 4 / 4 changed to 2 / 2, so it can be confidently said that it was then Lambada completely lost its resemblance to the karimbo. Lambada was danced with bent legs, steps were made from side to side and never from front to back. In a fashion were tight skirts, and it happened so that they began to be associated with the Lambada, and Lambada with them. Even nowadays in some places (for example in Lambar in the nightclub of the city of Sao Paulo) we can steel meet the classic couples: a lady in a narrow skirt and a man in long trousers. (Kempley 1990) Together with the Trio-eletricos (great mobile platform in which musicians perform dancing and singing during the Carnival) Lambada began to spread along Bahia and settled in the town of Porto Seguro. During the first boom of Lambada in the south-eastern region of Brazil (the most economically developed) it refered to the rhythms that came from Bahia, and were assumed that all these rhythms live only in the summer and then die. While all acknowledged that the Lambada was a real rush of the summer, many early lambaterii (places where the Lambada was danced) wewre closed closed in winter when tourists left. However, Lambada did not die The story of Lambada spread to Europe says that one day in late summer, several French businessmen came to Brazil and bought the music rights to 300 songs in the style of Lambada. Then they returned to France and organized a group Kaoma, investing lot of money in its promotion. In that way the Lambada style became known throughout the world and reached even the Far East, where it has remained to this day. The world fever of Lambada was so strong that it even returned to Brazil, to the most economically developed south-eastern region, that has already forgotten it. The fact that today in Brazil there are thousands of schools of ballroom dancing, great competitions and tens of thousands of dancers is a merit of the French Kaoma and their international success. This second wave was called the Second Boom of Lambada and this event greatly influenced the world culture. First of all Lambada became an international phenomenon, when millions of young people again began to dance in pairs, and evoked a wave of interest to the Latin American culture. Having spread around the world, the dance has changed dramatically. Due to the fact that in Europe there was lack of good dancers of Lambada (for example for movies and shows), most professionals had to make changes to it: the Lambada was added with whirling and steppe-like elements from jive and East Coast swing, as well as some acrobatic movements. Many dancers have begun to mix Lambada with other musical styles, trying to create something new and unusual. As to the Lambada music, it was played on all radio stations, and some musicians (eg, Sidney Magal and Fafà ¡ de Belà ©m),trying to follow this new vawe, created new real hits on its basis. However, pretty soon people discovered that their interest to the Lambada was based solely on efforts to earn more money, and these musicians were quickly forgotten. After some time, many composers of Lambada seemed to be forgotten, these music and dance were losing their power, and millions of fans around the world were helpless before it.
