Analysis of Cusp Catastrophe Model

Analysis of Cusp Catastrophe Model Social Psychology of Sport Critical discussion on cusp catastrophe model and using its principles of anxiety on an athlete’s performance. Introduction The ability to cope with pressure and anxiety under strenuous conditions such as a large sporting event is an essential skill to have, especially for an elite level athlete. Anxiety can be associated with an unpleasant state of mind, which can have different effects on performance. There have been many reported situations among athletes relating the feeling of being anxious or stressed in different sporting events. Dias et, al (2009) have participated in a research reporting 550 results among different level athletes linking to stress and anxiety to an important event. Some research have been shown that there were decrease in performance in correlation to anxiety such as memory, complex motor tasks such as shooting into the hoop in basketball () or indoor rock climbing (). However, there have also been positive anxiety correlations on performance regarding rebound shot in basketball and () have shown to have improvement in motor tasks skills such as anagram-solving. However, the relationships between anxiety and performance have been difficult to explain. Things such as methodological flaws, lack of operational definitions and unclear theoretical construction all conjunct within different theories (). Hardy’s (1990) cups catastrophe model (CCM) has been attempting to explain the contradicting effects of anxiety on performance, using multidimensional construct model. Cusp catastrophe model The catastrophe theory was originally proposed by a mathematician Rene Thom (1975). Rene developed the model geometrically explaining all naturally discontinuities in the world. Hardy (1990) has then developed a model of anxiety and performance (), attempting to explain the contradicting findings that have been previously reported regarding anxiety on performance. The model is based on the view on anxiety performance as a multidimensional construct; it combines the cognitive components â€Å"interactive effects of anxiety-performance relationship, the facilitative effects of cognitive anxiety and hysteresis†(), and physiological arousals ‘the organism’s natural physiological response to anxiety-including satiations’(). Cups catastrophe model shows an interactive, three-dimensional model predicting the effects for cognitive anxiety in a form of worry and physiological arousal on performance. Cups catastrophe model proposes that there are a series of four relationships which exists between cognitive anxiety, physiological arousal and performance. Cognitive arousal (CA) components are explained as expectations and cognitive concerns about one self, their situation and potential consequences (). Physiological arousal (PA) component is regarded as physiological response to anxiety, such as pain, feeling sick or feeling uncomfortable (). The first predictor suggests that cognitive anxiety has a positive connection with performance, when physiological arousal is at the lower end of the spectrum. The second predictor shows to have a negative relationship with performance, when physiological arousal is high. Third, is when the CA is low, the PA is shown to have an inverted U-shaped relationship on performance. The final predictor suggests that, when CA is high and physiological arousal is increasing a break in the wave of performance surface occurs. The split factor suggests that there will be a catastrophic drop in performance from the upper performance surface to lower performance surface. Moreover, when the catastrophic drop has occurred, with the large reduction in physiological arousal it is possible to bring performance back to the upper performance surface ().The change that occur when cognitive anxiety is high and physiological arousal increases is called hysteresis, which occurs under the condition of high cogn itive anxiety but not low cognitive anxiety. Hysteresis can be explained as the condition within the model where performance can catastrophically decrease from the upper performance surface to the lower performance surface. However, with the decrease in PA levels below the level at which the catastrophic drop occurred performance of the athlete may increase. Analysing one of the quotes made by Jessica Ennis, (2011) who is a professional 100 meter hurdler, have said: Im really, really nervous before every event, she admits. There are different levels of nerves. Before the hurdles Im particularly nervous as its the first event and, once thats out of the way, I relax a little bit†. Using cups catastrophe model it can be seen that Jessica experience signs of anxiety, having different levels of nervousness throughout the event. It can be expected that her cognitive and physiological arousals are pretty high, as the pressure from an Olympic event such as crowd, competition, winning the gold medal or podium position could have an effect on her performance. So before the event Jessica’s anxiety levels are high, with cognitive anxiety being high and physiological arousal decreasing the hysteresis effect may occur with Jessica feeling the pressure. However, her personal coping strategies could help reverse that effect, bringing her ba ck to the upper performance surface when the competition begins. Balancing the high cognitive state and physiological arousal may help increase performance during the event. Straight after the event it can be seen that she may relax, so her cognitive anxiety and physiological arousal decrease straight after the event leaving her of being more stress-free. Moreover, if she had to perform the hurdles after a certain amount of time, cognitive anxiety could be in at the middle and physiological arousal being low, to maintain the concentration for her to progress on to the next tier. Critical discussion The cups catastrophe model can handle complex linear and nonlinear relationship simultaneously in a three-dimensional manner, with the use of high-order probability density within the model, the functions have the advantage of being able to integrate sudden changes within behavioural jumps in the hysteresis(). Researches by Hardy et al, 2010 have applied the theory behind the cusp model over two experiments, supporting the process and the theory behind performance catastrophes and anxiety by using it with high levels of trait anxiety with competitive environment. The second study was social pressure and ego within the competitive environment which suggest that the cups catastrophe model is plausible. Hardy at al, 2007 have also found that hysteresis did occur in high CA condition, with the significant drops in performance with the increase in PA and CA. Another study by Marshall et al. 2005 looked into how interaction effects of cognitive anxiety and physiological arousal on have an effect on golf performance. The research did confirm that using the model, it had a positive relationship in regards of different situations and how anxiety is coped. However, the research also indicated that even though the methodology is plausible other factors needed to be assessed, as the theory is multidimensional it is very complex. Edwards et al, 2002 on the other hand, implemented that the theory of cusp catastrophe model may be plausible; however other factors such as confidence could appear to play a significant part in the catastrophic performance. Also () has implemented that other models such as endogenous learning-by-doing (ELBD), supports similar fundamentals of anxiety literature. All of the studies and theories suggest that anxiety does have different effects on physiological arousal and on anticipation timing performance during competition and practice. Also most of the models do tend to support the hysteresis theory and the catastrophe phenomenon. Most of the literature supports the different implementation of anxiety which occurs within the human mind, however it is very complex and needs to be further investigated to find a greater explanation on how anxiety affects sporting performance. Conclusion Determining the effects on anxiety on performance is still ripe at this stage; there are plenty of implementations which could be added to all of the models and theories. However, with the use of combined theories it may help further explanation and elimination of how there are relationships within understanding of anxiety, and how potentially it could increase and decrease performance of the athletes. With the cups catastrophe model being one of the most used in the research, it cannot be overlooked that other factors may affect the relationship between anxiety and performance. With the implementation of cups catastrophe model researchers could use other models or theories to round up the conclusion.

Postmodernity as the Climax of Modernity: Horizons of the Cultural Futu

Postmodernity as the Climax of Modernity: Horizons of the Cultural Future ABSTRACT: Given that any society is endowed not only with a set of institutions but also with the particular pattern of self-reflection and self-description, postmodernity should be viewed as an epoch representing the climax of modernity and its self-refutation. Parting with traditional society, modernity represents the triumph of power-knowledge, the divorce between spheres of culture, the global social relations, the new institutions, the change in the understanding of space-time relations, the cult of the new, and the modernization process. While preserving the institutional set of modernity, the postmodern period casts into doubt the basic thought foundations of classical modernity. The horizons of the emerging cultural future should be viewed in the light of a positive synthesis of the postmodern reflexive pattern with the legacy of modernity. The final of the 20-th century became an epoch of the radical reconsideration of the legacy of modernity. Beginning from the fifties, the new postclassical period of development of Western culture and society appeared as a specific reality that was more radically coined by the end of sixties-beginning of seventies when, with the growth of the feeling of a radical break with the past, a pattern of postmodernist cultural reflection obtained its definite popularity. Philosophers and historians of culture are intensively debating the question whether the coming of this period marked the end of modernity or its climax opening the horizons of the completely unknown future . In any event, the change of the pattern of cultural reflection looks very important and deserves special attention for it evidently reveals... ... Baudrillard, Jean. The Illusion of the End.

Not a Laughing Matter: Effects of Tawa-tawa

Nigeria. Results ot the study snowed that botn the decoction and extract of E. hirta, at doses of 60. 4 mg/kg and 483. 0 mg/kg have a significant effect on the platelet counts of Sprague-Dawley rats. The RBC and WBC counts were not significantly affected, demonstrating that E. hirta does not affect the circulating RBC or the erythropoietic centers of the experimental animals, and it does not induce production or destruction of the WBC. The mean increases in platelet count in the decoction and ethanolic extract groups did not significantly differ, suggesting that oth preparations can be used for further studies.The difference in the mean platelet counts of subgroups who received the 60. 4 mg/kg and 483. 0 mg/kg doses was not significant as shown in Dunnet's test. This finding indicated that the platelet- increasing activity of E. hirta was not dose-dependent. The platelet-increasing activity of E. hirta was further evaluated by determining the effect of the plant material on stimulati ng platelet production in the bone marrow. In this evaluation, the dose and preparation (483. g/kg of the ethanolic extract) that produced the greatest numerical increase in platelet count during the initial evaluation was used. Anagrelide, a drug which inhibits the maturation of megakaryocytes into platelets, was administered to decrease the platelet counts of the test animals.After exposure to anagrelide, 483. 0 mg/kg of ethanolic extract was administered to 50% of the test population. Results of this further evaluation showed that the mean platelet count did not differ significantly in the group which received both anagrelide (125 pg/day) nd ethanolic extract of E. irta (483. 0 mg/kg) and in the group who were only exposed to anagrelide (control). This suggested that the platelet-increasing activity of E. hirta was not due to stimulation of the platelet production in the bone marrow. 0 In another study conducted by the students of St. Marys School in Davao, E. hirta was also foun d to increase the platelet counts of white mice (Mus musculus). E. hirta was prepared in a teabag form. The results of this study were not published, and therefore, no further information was obtained.In Nigeria, the effects of aqueous and methanolic extracts of E. hirta on platelet count, bleeding time, and clotting time were also investigated. The extracts of E. hirta were administered orally to albino Wistar rats. Platelet count, bleeding time, and clotting time were determined before, and at different time intervals after administration of the extracts. At 60 minutes, the aqueous extract reduced bleeding time by 54% compared to 49. 5% for methanolic extract, and the difference was significant.

Thrinaxodon Facts and Figures

Thrinaxodon Facts and Figures Although it wasnt quite as mammal-like as its close cousin, Cynognathus, Thrinaxodon was still a startlingly advanced reptile by early Triassic standards. Paleontologists believe this cynodont (a subgroup of the therapsids, or mammal-like reptiles, which preceded the dinosaurs and eventually evolved into the first true mammals) may have been covered in fur, and also may have possessed a moist, cat-like nose. Name: Thrinaxodon (Greek for trident tooth); pronounced thrie-NACK-so-donHabitat: Woodlands of southern Africa and AntarcticaHistorical Period: Early Triassic (250-245 million years ago)Size and Weight: About 20 inches long and a few poundsDiet: MeatDistinguishing Characteristics: Cat-like profile; quadrupedal posture; possibly fur and warm-blooded metabolism Completing the resemblance to modern tabbies, its possible that Thrinaxodon sported whiskers as well, which would have evolved in order to sense prey (and for all we know, this 250-million-year-old vertebrate was equipped with orange and black stripes). What paleontologists can say for sure is that Thrinaxodon was among the first vertebrates the body of which was divided into lumbar and thoracic segments (an important anatomical development, evolution-wise), and that it probably breathed with the aid of a diaphragm, yet another feature that didnt come fully into mammalian vogue until tens of millions of years later. Thrinaxodon Lived in Burrows We also have solid evidence that Thrinaxodon lived in burrows, which may have enabled this reptile to survive the Permian-Triassic Extinction Event, which wiped out most of the worlds terrestrial and marine animals and left the earth a smoking, inhospitable wasteland for the first few million years of the Triassic period. (Recently, a Thrinaxodon specimen was discovered curled up in its burrow alongside the prehistoric amphibian Broomistega; apparently, this latter creature crawled into the hole to recover from its wounds, and both occupants then drowned in a flash flood.) For nearly a century, Thrinaxodon was believed to be restricted to early Triassic South Africa, where its fossils have been discovered in abundance, along with those of other mammal-like reptiles (the type specimen was unearthed in 1894). In 1977, however, a nearly identical therapsid species was discovered in Antarctica, which sheds valuable light on the distribution of  the earths land masses at the start of the Mesozoic Era. And finally, heres a bit of showbiz trivia for you: Thrinaxodon, or at least a creature closely resembling Thrinaxodon, was featured in the very first episode of the BBC TV series Walking With Dinosaurs.

7 Strategies for Landing Your Dream Job (Even If You Arent Qualified)

7 Strategies for Landing Your Dream Job (Even If You Arent Qualified) â€Å"Do what you love.† This is pretty common career advice, and you’ve probably heard it before. There’s just one catch- how do you get to that dream job, the job you really want? Especially if you don’t really have the experience or qualifications you need? All is not lost. Assuming you don’t want to jump from, say, retail clerk to astronaut, there are ways to help boost yourself up into your dream job. 1. Know What You WantIf you don’t have a goal in mind, it’ll be awfully difficult to set your path to get there. Before you start combing job listings or working on your resume, it’s important to know what your goal is here. This is especially true if your dream job is a bit of a stretch, professionally. Winging it won’t get you ahead here.If you’re having trouble deciding what that dream job can be, there are fun tools like this interactive dream job quiz that can help you speed up the thought process by taking your interests and offering real-world odds of getting a related job. (Sadly, it turns out my odds of becoming a TV-watching spy aren’t super high.)If you’re still not sure about how to juggle what you want to do versus what you’re qualified to do, career coach Laura Berman Fortgang has some great advice about how to cut through the noise and figure out what you want to get from your career:2. Know Your ValueExperience is a great attribute to have in your job hunt, but it’s not the only one. You also need to look at the quality of that experience: the skills and knowledge you have accumulated over time. Whether you’ve been working for 1  year or 15  years, you have steadily built your skills and your professional value. When you’re crafting your resume, think about using a format that showcases your skills, instead of using the traditional chronological format where you list your jobs, working backwards.3. See the Job Requirements as Gui delines, Not Set in StoneIf you think of the job description requirements as more of a starting point than an ironclad list of requirements, it can help remove some of that mental block to applying to a job that may be a reach. While some things may be non-negotiable (such as particular skills), other things may be more flexible if you have equivalent skills or experience. For example, if a job description calls for a Bachelor’s degree but you have an Associate’s and a number of skills related to the job, don’t let that scare you off. Just make sure you emphasize the qualities and skills that you do have to support the job description.4. Set Your StoryEveryone loves a good story- and hiring managers like a story that shows how great a person would be for this particular job. Your resume is the snapshot of your skills and professional experience, but your work doesn’t end there. You need to help set the narrative. Are you the savvy underdog looking to trad e up your skills for experience? Are you a bold career-changer looking to translate your skills and experience to a new industry? Your resume doesn’t tell a reader everything about you- just the highlights. This is why a cover letter can be essential, even in these days of automated submissions. Not only is it a chance to add more key words (more on that in a bit), but it lets you add some color and context about who you are, and summarize why you’re such a great fit for this position.If you don’t have tons of experience, it’s also a way to start the conversation about how your skills bridge a potential experience gap. Give the reader a reason to keep reading, instead of flipping ahead to the next resume. Work on your elevator pitch, which is a quick, succinct headline that answers three questions: who you are, what you do, and what you’re looking for. That’s the line you can hit in your cover letter, in a summary statement/objective on your resume, and again in the interview. This is your chance to set up your brand.5. Outsmart the Resume RobotsThese days, there’s a good chance that the first reader of your resume/application package isn’t even human. No offense to the robots out there, but this is not ideal if you’re trying to punch above your weight class, professionally. The smartest thing you can do here is know exactly what the company is looking for- and you have the job description right in front of you to help you do that. Make sure your resume and cover letter are hitting the key words that jump out of the job description- especially the ones related to experience, education, and skills. This is also where careful proofreading of your resume comes in handy; you want to make sure that your high-priority key words are spelled correctly, and match the way they’re presented in the job description. You don’t want to lie, but if you’re trying to get somewhat creative with y our qualifications, hitting as many of the key points from the job description as possible may get you past the first round, and one step closer to an interview where you can wow them with the skills you do have.6. Network Like CrazyYour network isn’t just a nice little collection of Twitter handles or LinkedIn headshots. These are people whose experience and professional kinship can help boost you from faceless applicant to contender. According to LinkedIn, a whopping 85% (!) of jobs are filled by network referrals. Why is this? Filling open jobs is time-consuming and expensive, and companies like to feel good about the choice and investment they’re making.Having someone else vouch for an applicant can help make that process easier, and push the applicant higher on the list than they might have made it if they just went through the usual process of 1) find job; 2) apply online; 3) wait for HR rep to call. Having someone talk up your skills and fitness for the job is i mmensely helpful. And you never know when an opening or an opportunity may pop up from your old boss, or that guy who sat next to you in Accounting class. Keeping these relationships fresh, and making an effort to attend industry events or networking events is definitely worth your time.7. Package Yourself CarefullyYou already know you need a resume, but that’s merely the first step. If it’s been a while since you redid your resume from scratch, guess what? Now’s the time to burn that sucker to the ground (not literally- no fire hazards, please) and create a new one for the opportunities you want:What Your Resume Should Look Like in 2017Here’s the Number One Resume Mistake You’re MakingWhat’s the Best Format for Your Resume?Your 5-Question Resume ChecklistAnd as always, it’s important to make sure you’re tailoring your resume to match the job you want. Customizing your resume doesn’t take long, and it can mean the differ ence between Joe, the Generic Okay Job Applicant and Joe, the Impressive Interview Candidate Who Would Fit in At Rodeo Clown Inc.But don’t neglect the other pieces here- the cover letter can be an essential part of your applicant package, especially when you’re trying to level up:Important Cover Letter Trends in 2017 That Will Help Your Job Search5 Must Haves for an Effective Cover Letter4 Steps to Writing a Kick-Ass Cover LetterAnd don’t skimp on interview prep, so that you’re ready when the call comes. Make sure your interview outfit and lucky shoes are ready to go, and get yourself in interview fighting shape:7 Real Life Interview Mistakes You Can Learn FromThe Most Important Talking Points for Your Upcoming Interview12 Easy Steps to a Successful Job InterviewIt also can’t hurt to brush up on what not to do. A few cautionary tales can help your interview game when the time comes:5 Reasons You Just Had a Really Bad Interview10 Personal Things Not to Say in an InterviewAfter all, this is your dream job, and you don’t want to feel like you’re scrambling to cover weaknesses or a lack of experience. The more you practice and work on your total package, the smoother you’ll look when you’re finally presenting yourself as the ideal applicant.

POLicy ANALYSIS Essay Example | Topics and Well Written Essays - 500 words

POLicy ANALYSIS - Essay Example The policy makers therefore adopt different strategies for addressing the concerns of nurses as these approaches can be more beneficial and less costly for the nurses as well as the patients. The nurse workforce in a particular hospital is based on licensed practical nurses, registered nurses and licensed nurses and then there are nurses’ aides. Both the LPNs and RNs are licensed by the same State in which they reside and practice. It is the responsibility of the RNs to access the needs of the patients, administration treatments and medications and develop patient plans. The maintenance of the minimum nurse to patient ratio will be beneficial for the patients as well as the nurses. There is a need for the policymakers to realize not only the potential benefits associated with the ratio but also potential expenses associated with these benefits. Minimum nurse staffing ratio helps the hospital to improve as well as increase the quality of its operations. The patients are more satisfied by the working of the staff and there are enough nurses present in the hospital to deal with emergency cases which results in low mortality rates. Acquiring minimum nurse staffing ratio also allows the hospital to give their full attention to each and every patient and not neglect the needs of any of them. On the other hand not having adequate number of nurses will misbalance the effective working of the hospital and the lives of many patients will be at stake. Aiken, Clarke, Sloane, Sochalski, & Silber in their article empahsize upon the importance of staffing ratio on the health of patients. There is no doubt about the fact that the staffing ratios help to alleviate the shortage of nurses. It discusses the fact that the working conditions of the hospitals may affect the number nurses willing to work within an hospital. Therefore staffing ratios help in improving the quality of hospitals which affect the patients’ mortality rate and

Roger Shimomuras Artwork Essay Example | Topics and Well Written Essays - 2000 words

Roger Shimomuras Artwork - Essay Example Examining the largest painting in the exhibition YELLOW TERROR, it is evident that Roger Shimomura uses the caricatures of Japanese soldiers, which are represented as individuals or types who crash, tumble and collide. Roger Shimomura himself is at the center of this chaos which pushes his eyes into a slant as if creating the nightmare mental picture of the Japanese caricatures done by his sight getting altered. The use of the First World War postcards shows how Roger Shimomura has copied caricatures in a precise manner to show how the postcards ridicule the Japanese army’s enemy as a fox, a snake, a beetle, a pig and a monkey. However, it is evident from the caricatures that Roger Shimomura has only borrowed the human caricatures and they exactly indicate how Roger Shimomura’s art relates to the sources of which they were found. Roger Shimomura has created a composition with the cartoon sources as the satire of a grand manner of the 1950s American art at a time when he was coming of age. However, it must be emphasized that the accumulation of the sources and the sources themselves in Roger Shimomura painting are representing more than a formal reference. The artwork also represents a social context. The YELLOW TERROR is a representation of how the society was racist against the Japanese and the Chinese to a point whereby they classified them into one class and making no good distinction between the Japanese and the Chinese but making the distinction only on racist’s grounds.
