Theories Of Motivation In High Risk Sports Psychology Essay

Theories Of Motivation In High Risk Sports Psychology Essay Introduction This Chapter will attempt to give the reader a greater understanding of the windsurfing and the definitions and theories of motivation. It will use previous research that has been carried out to examine further some of these theories and observe consistencies and in-consistencies in the area of motivation in sports, outdoor sports and high risk sports. It will then use this information to Purpose of Research Justification Clarification of Terminology Historical Background of Windsurfing In the late 1940s, Newman Darby discovered how to sail a three metre sailboat without using a rudder by leaning the sail towards the fore and aft of the boat. It was not until 1964 that he designed the first universal joint, a component that connects the sail to the board that allows it to move in any direction (http://windsurfingmag.com/how-to/2008/03/26/windsurfing-glossary/). It was not until 1968 that Californian surfer Hoyle Schweitzer and Sailor Jim Drake got together and using Darbys ideas created the first windsurfer. They patented their design and in the 1970s began to produce it widely. It was Darbys concept of the Universal Joint that was at the core of their design that allowed the windsurfer to be steered without a rudder. Initially the windsurfer consisted of only one board which beginners learnt on and experts prevailed on. Everyone used the same kit regardless of the conditions or skill. (http://www.windsurfing-academy.com/information_bank/history/the_history_of_windsurfing.asp). The board was made from polyethylene, was 12 feet (3.5m) long and weighed 60 pounds (27kg) By the late 1970s windsurfing had taken a firm hold of America and Europe with one in every three households in Europe possessing a windsurfer. (http://www.windsurfing-academy.com/information_bank/history/the_history_of_windsurfing.asp, The Windsurfing Movie, 200?) The first world championships for windsurfing was held in 1973 and windsurfing became an Olympic sport for men in 1984 and in 1992 for women. Patent Abstract: Wind-propelled apparatus in which a mast is universally mounted on a craft and supports a boom and sail. Specifically a pair of curved booms are accurately connected athwart the mast and secure the sail there between, the position of the mast and sail being controllable by the user but being substantially free from pivotal restraint in the absence of such control. http://inventors.about.com/od/wstartinventions/a/windsurfing.htm Development of Windsurfing This section will look at how windsurfing has developed both in relation to the equipment designs and the attitudes towards it. It will also look at where windsurfing is today and attempt to predict the direction it may be heading towards. Definitions of Motivation For the purpose of this research it is important to understand what is meant by the term motivation. This section provides several definitions for motivation along with further information to bear in mind about the term motivation The term Motivation is derived from the Latin word movere meaning to move (Onions 1996) cited in (Moran, 2004). The concept of motivation can be defined as The hypothetical construct used to describe the internal and/or external forces that produce the initiation, direction, intensity and persistence of behaviour (Vallerand Losier 1999) cited in (Vallerand Rousseau, 2001) Motivation can also be defined as being concerned with those factors which initiate or energise behavior (Moran, 2004, p. 38). Sage (1977) cited in (Festeu, 2002) states that motivation is the energizing element of personality which is reflected in individuals direction and intensity of effort. Within the field of sports psychology motivational issues are implicated when a person undertakes a task at which he or she is evaluated or enters into competition with others, or attempts to attain some standard of excellence (Roberts, 2001, p.6) cited in (Moran, 2004, p. 38). Various theories of motivation will be looked at in greater detail within the next chapter Theories of Motivation. According to Roberts (2001) cited in (Moran, 2004), motivation is one of the most misunderstood constructs in sports psychology. Roberts (2001) states there are three reasons for this. Firstly motivation is often confused with arousal. Roberts (2001) states arousal needs to be channeled in a specific direction for motivation to occur. Secondly Roberts (2001) states that motivation cannot be enhanced through positive thinking as commonly believed. Research on goal setting shows peoples objectives have to be controllable and realistic to be effective. Finally some coaches believe that motivation is inherited genetically something which is also contradicted by research which shows motivation can be changed through appropriate instruction. Roberts (2001) cited in (Moran, 2004, p. 39). Arousal Theories of Motivation Introduction This section will look at the various theories of motivation that have been developed over the years. These theories are not all directly relevant to the subject of this research but are necessary to allow a greater understanding of the area and theories, both past and current, of motivation. It will also look at the different types of motivation and the different factors that affect them. It will draw on information from various studies using these theories to attempt to develop a further understanding of these theories and how they are relevant to the areas of said studies. Instinct Theory Most current sports psychology can be traced back to William James (Model, 2005). James (1890) published an article called What is instinct. James suggested that interest plays an essential role towards attention and consequent behaviour. This theory bears many similarities to the Self Determination Theory proposed by Deci Ryan (1985). The Self Determination Theory will be further discussed later in this section. Sigmund Freud (1915) provided one of the earliest theories of motivation reviving James theories. Freud (1915) cited in (Model, 2005) suggested that individuals are passive beings and are moved by instincts, the main two being sex and aggression. Together these formed Freuds (1923) Instinct Theory (Model, 2005), (Vallerand Rousseau, 2001). A major criticism of Freuds theory is that instincts can be hard to identify. Freuds theory also fails to take into account the effect the environment may have on motivation. (Silva III Stevens, 2001). Need Achievement Theory The Need Achievement Theory considers both personality and situational factors as important predictors of behaviour. (Atkimson, 1974) cited in (Festeu, 2002). Personality refers to an individuals drive towards success and avoidance of failure. Murry 1938 Atkimson 1974 festeu(3) Drive Theory Drive Theory is an expansion of Freuds Instinct Theory put forward by Clark Hull (1948). Freuds Instinct Theory was originally named the drive theory but was later re-named. (Model, 2005). Hull concluded that motivational behaviours derive from one of four drives: sex, hunger, thirst and pain avoidance. A drive occurs and provides energy for action Hull (1938) cited in (Model, 2005). Hulls theory creates a link between instincts or drives and behaviour. According to Hulls theory, as these drives occur, such as hunger, we become motivated to reduce these drives to zero in this case by eating. This is the first theory that implies extrinsic motivation. (Model, 2005). Flaws observed within Hulls Drive theory came to light as better understandings of arousal and its effects on people came to light. Arousal will be discussed further in the next chapter Factors That Affect Motivation in Sport. Hulls Drive Theory also did not take into account of the differing levels of motivation between different tasks and individuals. (Silva III Stevens, 2001) Maslows Hierarchy of Needs Self Determination Theory The Self Determination Theory is a model of human motivation that stems from the innate needs for competence, autonomy and relatedness within the environment. It provides an over-riding framework for intrinsic and extrinsic motivation. (Baldwin Caldwell, 2003) The Self Determination theory proposes that these psychological needs and the social environment will determine one of many motivations. Each motivation can have varied effects on our thoughts, behaviours and feelings. These motivations fall along a continuum and are all connected to each other (Deci Ryan, 1985) cited in (Model, 2005) Self Determination Theory (cooke, Fielding).pngCited in (Cooke Fielding, 2010) As the scale above displays, motivation can be divided into six different forms from intrinsic motivation at one end of a scale to extrinsic motivation at the other end (Deci Ryan 1985) cited in (Baldwin Caldwell, 2003). Amotivation refers to no motivation at all. (Baldwin Caldwell, 2003) describe it as a way of describing behavior which is neither regulated or intentional. Extrinsic Motivation Extrinsic motivation refers to engaging in an activity as a means to an end and not for its own sake (Vallerand Fortier, 1998) cited in (Moran, 2004, p. 40). It can be separated into non-internalised and internalised, as displayed in the diagram above. Internalised forms of extrinsic motivation carry some intrinsic factors contributing towards behavior but the primary reasons are still external. External Regulation External regulation is the most extreme form of extrinsic motivation. (Baldwin Caldwell, 2003). This refers to the doing of an activity solely to satisfy external demands such as for a reward or to avoid punishment. Introjected Regulation Introjected regulation is based on self controlled, ego orientated behavior that is usually driven by what others may think. Introjected motivation is not autonomous but rather externally focused behavior usually carried out to avoid guilt of anxiety or to maintain status or feelings of self worth. (Baldwin Caldwell, 2003). Identified Regulation Identified regulation has elements of intrinsic motivation but behavior is undertaken for primarily external reasons. (Baldwin Caldwell, 2003). An example of this is cross-training in sports. Windsurfers may partake in other exercises such as running or cycling not for the enjoyment but to maintain or increase fitness for windsurfing. They may enjoy the running or cycling but this is not their primary reason for participation. Integrated Regulation Integrated regulation is the most autonomous form of extrinsic motivation. A person carries out this behavior because it represents what they stand for. This can be demonstrated amongst volunteers for non-profit organisations. They carry out behavior for external rewards often with little compensation or direct benefit to themselves. Intrinsic Motivation Intrinsic motivation refers to peoples reasons for undertaking an activity for itself and the pleasure and satisfaction derived from participation (ibid., p.390) cited in (Moran, 2004, p. 39). This can also be described as the pursuit of an activity that one finds interesting and is engaged in for the inherent satisfaction derived from participation. (Baldwin Caldwell, 2003). Factors that Affect Motivation and Participation in Sports This section will observe the varying factors that encourage or discourage participation in sport or physical activity as a whole. It will draw on information gathered from the previous chapter and relate them directly to sport using research already carried out in the area of motivation in sports (5 buzz junkies) (8 understanding participation in sports) (The Art of Healthy Risk Taking) Motivation in Outdoor Activities This section will attempt to further explore the area of motivation towards the area of outdoor activity. It will explore motivational factors in various areas and various sports that draw from the natural environment to provide a medium to undertake the specific activities. It will also draw on research already carried out in this area to attempt to develop a greater understanding of any consistencies or in-consistencies in this area. Arousal (5 buzz junkies) (The Art of Healthy Risk Taking)(festeu 4) Risk Taking Nature and risk in adventure sports Philosophy, risk adventure sports Is Windsurfing an Extreme Sport? Windsurfing is commonly regarded as an Extreme sport however this term may be misleading. This label was attached to various alternative sports by the media originally in North America in an effort to attract the more lucrative teenage audience. (Dant Wheaton, 2007). The term High Risk is now commonly used by researchers in the field of these sports in place of the term extreme. It can be observed that the majority of windsurfing practised by most windsurfers cannot be described as high risk due to the fairly low risk of injury. (Dant Wheaton, 2007). It is important to remember that the more hazardous conditions attempted by many windsurfers by entering the seas in winds upwards of gale force and large swells still constitutes a high risk environment to enter. With this in mind, windsurfing can only really be described as a high risk sport when undertaken in such adverse conditions that if gear failure or rider error were to occur, self rescue would be close to an impossibility. This section will examine risk taking both real and perceived in the area of motivation and attempt to create an understanding of how this may alter individuals attitudes towards general activities and then specifically high risk sports. (The Art of Healthy Risk Taking) (To the Extremes out of the gene pool) What is even stranger is that some people go beyond being observers and take real risks, and expose themselves to real harm of 2 DANGER one kind or another, and that they do so completely voluntarily. Why do people, of their own free will, participate in such activities as sky diving, mountaineering, bungee-jumping, white-water rafting, big wave surfing, pot-holing, base jumping, cave diving, and hang-gliding? In this respect, it is interesting that new forms of voluntary risk are continually emerging or being invented in different parts of the world, and this seems to have been particularly true in the last decade or so. (Danger quest for excitement) Environment This section will examine how the natural environment can affect attitudes and motivation towards participation in activities.

Other activities in this catagory include skateboarding, snowboarding and the resurgence of surfing.

Wireless Power Transfer

IntroductionWe can non conceive of modern universe without power and twenty-four hours by twenty-four hours, the use of power is increasing, but utilizing it in the most effectual manner is the biggest concern now. After the radical alteration in engineering site, sometimes the manner of power transportation is a weighty issue. Wireless power transmittal is necessary in instances where fleeting power transportation is needed, because sometimes semisynthetic music directors are non perfect for power transmittal in few sectors. Wireless Power Transfer ( WPT ) is a transmittal where electrical energy is transmitted from a power beginning to an electrical burden through an air spread with the aid of electromagnetic field. In last few old ages, there is a dramatic advancement in this sector but still it is in child degree. Background and aim Wireless power transmittal is a construct which was proposed by Nicola Tesla in the late 1800s.That clip it may sound futuristic, but Tesla’s did it enormously. No uncertainty research workers have found safer and more effectual methods of wireless power transportation, since Tesla ‘s cardinal check. It is called resonating inductive yoke, the most promising engineering that has been bloomed. The engineering takes advantage of moving ridge harmonics. From two spirals, wave harmonics make a strong nexus of magnetic moving ridges and vibrate it. Although the original initiation spiral was created by Nicholas Callan ( 1799-1864 ) , in 1836 a priest and the professor of natural doctrine, but Nicola Tesla’s spirals created the discovery for Wireless power transmittal. The chief point is why we want to utilize wireless engineering to route information when all the maps can be arranged with wired elements? Extinguishing reckons of overseas telegrams is the lone existent reply. Many medical equipments require a uninterrupted power beginning. If wires may set-up through someone’s organic structure, the hazard of shorting causes a hazard of infection for patients. Cell phones, earphones, game accountants, personal digital helpers ( PDAs ) and Internet contraptions all require a three to four pes single wire to utilize in the auto. Most of these wires are created an uncomfortable environment in the wire. WPT utilizing magnetic: Wireless Power transportation ( WPT ) is divided by two parts, one is near-field and another one is far-field parts. Although Radio Waves and LASER engineering are widely used for far-field part, but these are non excessively much efficient for near-field part. In near-field part, three techniques of wireless power transportation are used. Air ionisation is one of them, but it is a toughest technique and is non executable for practical execution. Other two techniques are really effectual, which are called magnetic inductive yoke and magnetic resonance inductive yoke. Magnetic inductive yoke is the most comprehensive method of wireless power transmittal. Interior designers can acquire some benefits from magnetic initiation instead than the wireless moving ridges. If modulated magnetic field is used to direct a signal through the air allows for a low-priced, low-power communications system. Radio waves communicate by distributing a plane moving ridge in unfastened infinite. On the other manus magnetic system is based on quasi-static magnetic field which is around the transmission spiral. It is based on the rule of change overing and conveying the magnetic flux ( ? ) between two spirals ( primary and secondary spirals ) which are non connected by wires. Transformer, electric coppice, radio bear downing tablets are the illustrations of magnetic initiation. But this method is impractical when it comes to reassigning power to longer distances. For such an experiment, it is needed that the spirals are excessively close to each other so that the short magnetic field is produced. When it is a affair of long distance, a immense magnetic field is needed and spirals should be multiple. Due to the flow of magnetic field in different waies, counter steps should be calculated to salvage the power loss. May be this is theoretically possible but is non possible practically. Magnetic resonance inductive yoke is the procedure which is used for longer distances power transportation. It is a combination of inductive yoke and resonance. Resonance is interacted with two objects really strongly. In this procedure capacitance is connected parallel to the spiral and spiral provides the induction. The resonating capacitances wipe out the divergent induction in the receiving system. Resonance Inductive Coupling ( RIC ) is extremely effectual than inductive yoke ( IC ) and RIC can be transfer power to multiple devices whereas inductive yoke is reassigning power to individual device. Magnetic initiation vs. Radio Waves: Magnetic initiation can keep a scope bound which is around 3 metres. On the other manus, wireless waive is non governable and range bound is minimal 10 metres or more. Related work: When Tesla spiral is invented, the thought of wireless power was unveiled. Now â€Å"WiTricity† is an American technology company, but in 2007 WiTricity was a undertaking of MIT pupils, where research workers were able to successfully light a 60 W visible radiation bulb wirelessly, which was 7ft off. At a glimpse, it is originally extended version of magnetic initiation up to a few metres. The chief difference is resonance ; if the magnetic resonance is same for transmitter and receiving system, energy can expeditiously be transferred and loss of power is really little. Using resonance is about 106 times efficient than without resonance. The frequence of resonation can be measured by the equation given below. Resonant Frequency = Coil Inductance x Capacitance The dramatic accomplishment of the MIT research squad is how to ticket tune the application so that the close field addition distances for a few metres, on the other manus restricting the power radiated through the far field. In 2008, Tesla’s experiment was rebuilt by Intel, which was wirelessly powering a light bulb. And in 2009, Sony exhibited a Television, which was wireless-powered at a scope of 20 inches. Very recent April 17, 2014 was another discovery for Wireless power transportation utilizing magnetic resonance. Chun T. Rim, a professor of Nuclear & A ; Quantum Engineering at KAIST and his squad developed a system, which can bear down 40 smart phones at the same time, with a highest end product power of 209 W at 20 kilohertz and power beginning can 5 metres off from receiving system. The name of this system is â€Å" Dipole Coil Resonant System ( DCRS ) † which is an drawn-out version of inductive power transportation. Using this system a big LED Television with 40 W-fans can be powered from maximal 5-meter distance.No uncertainty, that it is a radical accomplishment after WiTricity. Advantages 1. Wireless charging: Now inductive bear downing has promised with our nomadic devices, Electric Vehicle wholly free from cord and it protects our connexions. When electronics are enclosed, there is no opportunity of corrosion. Sometimes embedded medical devices are needed to be charged, but the hazard of infection, wires penetrate through tegument should be avoided. Durability is another benefit of inductive charging. 2. High Efficiency over a Distance: Electricity, which is created by the beginning and is extremely efficient around several metres. 3. Penetrate and Frisk Around the barrier: Power transportation system is really flexible for industrial or commercial environment. Most of the edifices are furnished by wood, glass, plastics, fabrics etc. which are non created any obstructor of transmittal system. In add-on, the system has an ability to frolic around many metallic barriers. 4. Control the scope of power degree: It is possible to accomplish commanding power degree over distance. Wireless mouse and keyboard like electronic devices need milliwatts and when it is a affair of electric rider vehicle, so it gives you kilowatts. 5. Safe for nature: Cause of magnetic near field, this engineering is wholly free from Radiative manner and that’s why it is safe for nature. Biological beings are really decrepit interact with magnetic field. The world-renowned physicist Sir John Pendry of Imperial College London explains: â€Å" The organic structure truly responds strongly to electric Fieldss, which is why you can cook a poulet in a microwave. But it does n't react to magnetic Fieldss. Equally far as we know the organic structure has about zero response to magnetic Fieldss in footings of the sum of power it absorbs † . Research Aims: Wireless coursers for Electric Vehicles ( EVs ) would be a convenient characteristic, which is given a great solution of avoid to retrieve the stopper in a power overseas telegram after parking the vehicle. Wireless bear downing for Electric Vehicles is a system necessitating high electrical power ( up to 100s of kW ) and broad country of wireless power transmittal which increases electromagnetic field exposure. There are two types of radio bear downing engineerings applicable for EVs. inductive power transportation ( IPT ) system, which is known as Decision: The Wireless Power Transmission was a legendary effort by Nikola Tesla. After 120 old ages, reproduced of Tesla’s experiment agencies, necessity of engineering can ne'er be hidden.

Although â€Å"WiTricity† and â€Å" Dipole Coil Resonant System ( DCRS ) † are about new engineerings, but the cardinal rule is magnetic inductive with resonance yoke. However, the most update radio power transmittal system is excessively dearly-won and immature, but the twenty-four hours is non so far when wireless power transportation utilizing magnetic is the most diacritic and sustainable option of current system.

Creating Corporate Advantage Essay

Most executives focus on individual elements of their resources, business, and organization without integrating all the parts into a whole. First, it is important to understand what a good corporate strategy is. According to the authors, it is not a random collection of individual building blocks, rather a fully constructed system of interdependent parts. In order for the organization to thrive, executives must actively direct decisions about resources the corporation will develop, and the business in which it will compete. During this, the executives must make sure all elements are aligned with one another. By applying the triangle of corporate strategy, the strengths of all special assets, skills and capabilities will illustrate how each element "fits. " The Resource Continuum is another model that shows the basis for corporate advantage along a continuum. This model can be applied differently to different business, as one size does not fit all. Many companies choose to integrate other businesses based on products rather than resources, and end up with a "plain vanilla" infrastructure. By following this continuum it will constrain the set of businesses to compete in while limiting th There is no one best way to design a product, make a product, manage operations, or serve customers. The â€Å"best way† depends on a firm’s objectives, resources, competencies, and context (products and customers). Firms choose to compete in different ways. A firm’s strategy defines how it will compete in the marketplace–its own best way. Strategy formulation involves (1) defining the primary task, (2) assessing core competencies, (3) determining order winners and order qualifiers, and (4) positioning the firm. The secret to effective strategy? Excel on the order winners, meet the order qualifiers, capitalize on core competencies, and maintain focus. Corporate strategy drives functional strategy. Functional strategies must be consistent with and supportive of corporate strategy. Strategic decisions in the operations function involve products and services, processes and technology, capacity and facilities, human resources, quality, sourcing, and operating systems. Policy deployment is a planning system that helps align day-to-day operating decisions with the company’s overall strategy.

A Bittersweet Situation Of The Food Industry Essay

Emily Carrizales D. Taylor ENGL 1301 8 December 2016 A Bittersweet Situation The delicious burgers and snacks that people eat on a daily basis are jam packed with unhealthy amounts of sugar, sodium, and trans fats. Most Americans are aware that junk foods are bad for their health, but they continue to eat it anyway. The vicious cycle of the purchasing and consumption of processed foods is perpetuated by the fast paced American lifestyle. Therefore, people are continuously eating foods that are detrimental to their health. Americans should reduce the amount of processed foods that they consume because an excess of processed food negatively affects their health. A large portion of companies in the American food industry are more interested in the profits of food production than the well-being of the consumers. The competitive food market nowadays leads some companies to adopt practices that benefit itself more than the consumers. In modern America, it is convenient for some big companies to produce snack foods that contain little to no nutritional value at an inexpensive price. In order to keep business up and running, it is important to do whatever is necessary which includes leaving out extra expenses. Companies often use entertaining advertisements and attractive food packaging to distract the consumers from this fact. While Americans reap the benefits of quick snacks and meals, they are consistently enjoying foods that are subtly detrimental to their health.
