Sultans of the Swahili Culture

The Kilwa Chronicle is the name of a collected genealogy of the sultans who ruled the Swahili culture from Kilwa. Two texts, one in Arabic and one in Portuguese, were written in the early 1500s, and together they provide a glimpse into the history of the Swahili coast, with particular emphasis on that of Kilwa Kisiwani and its sultans of the Shirazi dynasty. Archaeological excavations at Kilwa and elsewhere have led to a reappraisal of these documents, and it is clear that, as is typical with historical records, the texts are not to be completely trusted as both versions were written or edited with political intent. Regardless of what we today consider the reliability of the documents, they were used as manifestos, created from oral traditions by rulers who followed the Shirazi dynasty to legitimize their authority. Scholars have come to recognize the chronicles semi-mythical aspect, and the Bantu roots of the Swahili language and culture have become less clouded by the Persian mythologies. Kitab al-Sulwa The Arabic version of the Kilwa chronicle  called Kitab al-Sulwa, is a manuscript currently housed in the British Museum. According to Saad (1979), it was compiled by an unknown author about 1520. According to its introduction, the Kitab consists of a rough draft of seven chapters of a proposed ten chapter book. Notations in the margins of the manuscript indicate that its author was still conducting research. Some of the omissions refer to a controversial mid-14th-century document which may have been censored prior to reaching its unknown author. The original manuscript ends abruptly in the middle of the seventh chapter, with the notation here ends what I found. The Portuguese Account The Portuguese document was also prepared by an unknown author, and the text was supplemented by the Portuguese historian Joao de Barros [1496-1570] in 1550. According to Saad (1979), the Portuguese account was likely collected and provided to the Portuguese government during their occupation of Kilwa between 1505 and 1512. Compared to the Arabic version, the genealogy in the Portuguese account purposefully obscures the royal ancestry of Ibrahim bin Sulaiman, a political opponent of the Portuguese-backed sultan at the time. The ploy failed, and the Portuguese were forced to leave Kilwa in 1512. Saad believed that the genealogy at the heart of both manuscripts might have been begun as early as the first rulers of the Mahdali dynasty, circa 1300. Inside the Chronicle The traditional legend for the rise of the Swahili culture comes from the Kilwa Chronicle, which states that the Kilwa state rose as a result of an influx of Persian sultans who entered Kilwa in the 10th century. Chittick (1968) revised the entry date to about 200 years later, and most scholars today are of the opinion that immigration from Persia is overstated. The Chronicle (as described in Elkiss) includes an origins legend that describes emigration of the sultans of Shiraz into the Swahili coast and their founding of Kilwa. The Arabic version of the chronicle describes the first sultan of Kilwa, Ali ibn Hasan, as a Shiraz prince who with his six sons left Persia for east Africa because he had dreamed that his country was about to fall. Ali decided to establish his new state on the island of Kilwa Kisiwani  and purchased the island from the African king who lived there. The chronicles say Ali fortified Kilwa and increased the flow of trade to the island, expanding Kilwa by capturing the adjacent island of Mafia. The sultan was advised by councils of princes, elders, and members of the ruling house, likely controlling the religious and military offices of the state. Shirazi Successors Alis descendants had varied success, say the chronicles: some were deposed, one beheaded, and one thrown down a well. The sultans discovered the gold trade from Sofala by accident (a lost fisherman ran across a merchant ship bearing gold, and related the story when he returned home). Kilwa combined force and diplomacy to take over the port at Sofala and began charging exorbitant​ custom duties on all comers. From those profits, Kilwa began constructing its stone architecture. By now, in the 12th century (according to the chronicles), Kilwas political structure included the sultan and the royal family, an emir (military leader), a wazir (prime minister), a muhtasib (police chief), and a kadhi (chief justice); minor functionaries included resident governors, tax collectors, and official auditors. Sultans of Kilwa The following is a list of Shiraz dynasty sultans, according to the Arabic version of the Kilwa Chronicle as published in Chittick (1965). al-Hasan bin Ali, 1st Sultan of Shiraz (before 957)Ali bin Bashat (996-999)Daud bin Ali (999-1003)Khalid bin Bakr (1003-1005)al-Hasan bin Sulaiman bin Ali (1005-1017)Muhammad bin al-Husain al-Mandhir (1017-1029)al-Hasan bin Sulaiman bin Ali (1029-1042)al bin Daud (1042-1100)al bin Daud (1100-1106)al-Hasan bin Daud bin Ali (1106-1129)al-Hasan bin Talut (1277-1294)Daud bin Sulaiman (1308-1310)al-Hasan bin Sulaiman al-Matun bin al-Hasan bin Talut (1310-1333)Daud bin Sulaiman (1333-1356)al-Husain bin Sulaiman (1356-1362)Talut bin al-Husain (1362-1364)al-Husain bin Sulaiman (1412-1421)Sulaiman bin Muhammad al-Malik al-Adil (1421-1442) Chittick (1965) was of the opinion that the dates in the Kilwa chronicle were too early, and the. Shirazi dynasty began no earlier than the late 12th century. A hoard of coins found at Mtambwe. Mkuu have provided support for the start of the Shirazi dynasty as the 11th century. Other Evidence The Periplus of the Erythrean Sea (Periplus Maris Erythrae) 40 AD, a travel guide written by an unnamed Greek sailor, mentioned visiting the eastern coast of Africa. The Islamic biographer and geographer Yaqut al-Hamawi [1179-1229], wrote about Mogadishu in the 13th century, describing it as a frontier between Barbar and Zanj, visited Zanzibar and Pemba islands. The Moroccan scholar Ibn Battuta visited in 1331, and, 20 years later wrote a memoir including this visit. He describes Mogadishu, Kilwa, and Mombasa. Sources Chittick HN. 1965.

Now or Never - 870 Words

Now or Never â€Å"When should we leave? Should we leave now?† I said to my friends Sean, Charlie, Nick, Ben, Megan, and Melanie. We were on our second day of spring break, in our high school senior year, getting ready to hit the road and get on our way to Destin, Florida. It was a frantic time before we were actually on our official way. Of course, it was traffic hour when we all decide to leave, that just added to the chaos. We weren t going on this trip alone though, we were going with a whole flock of people. There were seven parent chaperones and about fourteen other friends/ siblings and a couple of their friends too. With all of these people we obviously weren t going to fit into one car. We took three cars between all of us. and†¦show more content†¦We were slammed packed, but we were all young and nimble. We all loved each other dearly; we were all best friends. Now we have all the pieces to our puzzling friends together, and I finally caught back up to the rest of the caravan by dusk. It took us twenty-two hours to make it there. We had twenty-two hours left. Once we were there the wild times times began to brew. The guys and the girls each had their own condo, that alone I think says a lot about the mood of the trip. It was party party from the moment we arrived in Florida. Day three of the trip, I was enjoying some adult beverages since I was on vacation. Drinking is something we would do as a family when we went on vacation, mostly wine though.This time it was vodka and coconut rum, and just enough to make me feel great. In my mind, I was on top of the world. My buddy Sean’s parents rented a three wheel motorcycle/go-cart hybrid that I knew I could drive. Sean’s little brother drove it away from his parents with me in shotgun, aka the passenger s seat. This thing drove like a motorcycle, so I thought it could handle like a motorcycle. Corey, Seans little brother, squeezed the thing down the sidewalk to beat traffic and into the condominium parking lot. The condos we stayed at were right on a golf course. We drove around that place like we owned it. We took turns driving it. I went out the condo parking lot into the grass and back towards our condo with the throttle all the way down.

How can nutrition and recovery strategies affect performance Free Essays

string(97) " The foods eaten in the 30 minutes immediately after exercise should be medium to high glycerin\." Why is a well balance training diet essential for an athlete? A well balance training diet Is essential for an athlete. Good diet and nutrition can enhance sporting performance. Carbohydrates should form the basis of the sportsperson diet. We will write a custom essay sample on How can nutrition and recovery strategies affect performance or any similar topic only for you Order Now For most athletes, a varied healthy diet will provide vitamins and minerals, as well as protein, to promote growth and repair of muscle tissues. Adequate fluid intake is essential to help performance and prevent dehydration. 55. What are the relative recommended percentage of CHOC, Fats and Protein for a. Athletes b. ) Non-athletes 56. What are the pre-performance recommendations for an athlete? A pre- performance routine Is a consistent procedure that athletes use to prepare themselves for competition. It is recommended that athletes must time their carbohydrate intake, a substantial amount of carbohydrate (200-egg) in the 2-4 hours prior the event. The carbohydrate foods most suited to pre-exercise eating are low-fat, low-fiber and low to moderate in protein; these are less likely to cause gastrointestinal upset. Liquid meal supplements (such as a protein shake) or reverberate-containing sports bars (such as Powerboat Performance Bar) can be useful for athletes who suffer from pre-event nerves or have an unpredictable pre- event timetable 57. What is a carbohydrate loading? Explain the process. Carbohydrate loading Is a strategy Involving changes to training and nutrition that can maximize muscle glycogen (carbohydrate) stores prior to endurance competition. This diet typically involves a 3-4 day ‘depletion phase’ involving 3-4 days of hard training plus a low carbohydrate diet. This depletion phase was thought to be necessary to stimulate the enzyme glycogen synthesize. This was then followed immediately by a 3-4 day ‘loading phase’ involving rest combined with a high carbohydrate diet. The combination of the two phases was shown to boost muscle carbohydrate stores beyond their usual resting levels. 58. Why is it though beneficial? To what types of athletes? The extra supply of carbohydrate has been demonstrated to improve endurance exercise by allowing athletes to exercise at their optimal pace for a longer time. It is estimated that carbohydrate loading can improve performance over a set distance by 2-3%. An individual who exercises continuously at a moderate o high Intensity for 90 minutes or longer Is likely to benefit from carbohydrate loading. Typically, sports such as cycling, marathon running, longer distance triathlon, cross-country skiing and endurance swimming benefit from carbohydrate loading. 59. What is recommended for an athlete to eat/drink during competition? It is recommended that a sport drink containing 30 grams of carbohydrate and 1 5 grams of protein (In 500 ml water) per hour of exercise could be taken. With multiple events back to back, a larger amount of this beverage should be consumed 1 org recommended for an athlete to eat/drink after competition? Post-workout nutrition squires two things: protein to aid in protein synthesis and carbohydrates to replace muscle glycogen. Egg. Chicken breast (protein) with broccoli and brown rice (carbohydrates) 61 . What is meant by the term supplementation? The word â€Å"supplement† means exactly that: a nutrient or group of nutrients (vitamins, minerals, protein, carbohydrates, fats and oils) that are meant to supplement, but not substitute for a healthy diet that you eat on a regular basis. Nutrition supplements come in a variety of forms: pills, capsules, powders, liquids, and even in gel form. The cost of nutrition supplements can range from almost â€Å"at cost† to being outrageously expensive. 62. Are there any benefits of supplementation of vitamins, minerals, and protein to performance? The body is unable to manufacture vitamins, so diet must supply them as vitamins are essential to maintain bodily functions. Protein is responsible for the growth, repair and maintenance of body tissue the use of protein supplements is common amongst power and strength athletes such as weight-lifters, rugby league and rugby union players. 3. Are there benefits from the use of sports drinks; liquid meal supplements, calcium supplements; iron supplements? Why? The benefits of sports drinks are; Convenient, easy to consume 64. What evidence is there for against vitamins/minerals supplementation? Loss of time, effort and money. Overdoses of the fat-soluble kind are the real culp rits. The results of overdoses are many. For example, an overdose of vitamin A could cause ringing in the ears, blurred vision, hair loss and a host of other effects. Excessive quantities of some vitamins and minerals can be unnecessary, expensive and potentially dangerous. 5. What evidence is there for against creating supplementation? Creating is possibly unsafe when taken with a high dosage. There is some concern that it could harm the kidney and the liver, or heart function. Creating also causes muscles to draw water from the rest of the body and could cause dehydration. 66. What evidence is there for against caffeine supplementation? Caffeine can cause insomnia, nervousness and restlessness, stomach irritation, nausea and vomiting, increased heart rate and respiration, and other side effects. Caffeine can make sleep disorders in patients with acquired immunodeficiency syndrome (AIDS) worse. Larger doses might cause headache, anxiety, agitation, chest pain, and ringing in the ears. Large goes may be unsafe and can cause irregular heartbeats and even death. 67. Explain physiological strategies for recovery strategies? Egg. Cool down and hydration. Physiological recovery strategies aim to remove the metabolic by-products of exercise through a cool down period as well as replace lost fluids and energy. Cool down: The cool down, or active recovery, is a group of lower intensity exercises performed immediately after exercise to remove waste products, decrease muscle soreness (DOOMS), improve muscular relaxation, bring the cardiovascular system back to rest and allow time to reflect on the training or performance. This could involve short Jogging repetitions, slow swimming or similar low intensity activity. Static reduce the risk of injury. Hydration: To replenish fluid lost during training or games the athlete should consume approximately one litter of water for every kilogram of body weight lost. The addition of carbohydrates will speed up fluid replacement as well as refueling muscle glycogen stores. The foods eaten in the 30 minutes immediately after exercise should be medium to high glycerin. You read "How can nutrition and recovery strategies affect performance" in category "Papers" Sports drinks are useful because they provide fuel and fluid but should be limited to the 30 minute period following exercise. Solid foods, such as fruit, should be encouraged as they provide additional nutritional value. 68. Explain the neural recovery strategies for recovery egg. Hydrotherapy, massage. Neural recovery strategies such as hydrotherapy and massage help replenish the nervous system. The change in chemicals found in muscles following heavy bouts of exercise or psychological stress can be addressed by these neural strategies. Hydrotherapy: Hydrotherapy involves the use of water to relax, soothe pain and assist metabolic recovery whilst providing support for movements which eliminate Jarring and straining movements. Typical hydrotherapy methods include spas, underwater massage and swimming pools (heated and non-heated). Active exercise can be incorporated into hydrotherapy sessions allowing a gravity assisted environment. Massage: The main purpose of massage is to assist in reducing training fatigue. It can also be helpful in a preventative way in reducing localized muscle tension that can with time lead to overuse injury. 69. Explain the tissue damage recovery strategies egg. Cryptography Cryptography: Cryptography, or cold therapy, is the local or general use of low temperatures to remove heat from a body part. The goal of cryptography is to decrease pain and inflammation, promote vasoconstriction and prevent the build up of waste products. Various forms of cryptography have become popular as recovery strategies for many athletes. Examples of various forms are cryptography are ice packs and a Cryogenic chamber. 70. Explain the psychological recovery strategies, egg. Relaxation. Psychological recovery strategies aim to disengage the athlete from the performance. Heart rate, breathing and body temperature remain elevated post exercise and may take time to drop as do anxiety levels about the performance or true performances. Strategies such as relaxation assist to bring these levels to normal levels. Following intense training and demanding performances, athletes may experience symptoms of low concentration, lack of motivation and increased levels of anxiety. Psychological strategies can play an important part in emotional and possibly spiritual recovery by assisting in recovery of concentration, lifting motivation and decreasing anxiety levels. Some psychological strategies that can be used to enhance recovery are outlined below. Debriefing – Effectively evaluating a performance can be useful way to provide emotional and psychological support after training or competition. This should focus on the process not the outcome. Debriefing allows the athlete to achieve ‘closure’ with regards to a past performance and set goals for future performances. This is usually logical, rational discussion removed from the hype and the emotion of performance. Contingency planning – Simple strategies or distracted, such as mood-lifting activities, which are used in situations such as a major performance setback or traumatic event. Social support -Athletes need to build up a network of support contacts outside their athletic lives. Relaxation skills – These relax in many different ways, with some preferring to read a book, listen to music or watch television. Specialized relaxation techniques are also widely used, including meditation, progressive muscle relaxation, visualization, breathing exercises, positive self-talk and flotation. The athlete needs to practice only one or two techniques on a regular basis for these to become effective tools to use to aid recovery. The choice of relaxation methods is quite individual and involves experimentation to establish which technique works best. Rest and sleep – Rest days are essential and a least one ay per week should be a non-training day. This allows time for physical and psychological recovery as well as time for other interests and activities. Adequate sleep (7-9 hours) is regarded as probably the most important recovery strategy as it provides regeneration and restoration of the body’s systems to allow adaptation to training. Too much sleep however, can be detrimental, contributing to sluggishness and lethargy. How does the acquisition of skill affect performance? 71 . What is meant by the term ‘skill acquisition? Skill acquisition refers to the process that athletes use to learn or acquire a new skill. A skill can be defined as an act or task such as typing or drawing, or in the instance of sport, catching, throwing, and running. 72. What is meant by cognitive stage? The cognitive stage of skill acquisition is the early identification and understanding of the skill to be learned. Individuals focus on what to do, that is most of the learning activities during this stage will be in the mind, egg. Watching, thinking, analyzing, reasoning, Judging and visualizing, rather than lots of practice. During this stage the learner develops an in-depth understanding of the skill to be acquired. 73. What is meant by associative stage? The associative stage of skill acquisition really focuses on the idea of practice with the learner learning how to do it. Practice at this stage increases the learner’s ability to perform the skill or task. They may not necessarily perform the skill well but have an understanding of how to do it. Most learners stay in this stage for a long period of time, with most not progressing to the next stage. 74. What is meant by the autonomous stage? The autonomous stage of skill acquisition revolves around executing a skill automatically without having to stop and think about what to do next or how to o it. It is an advanced level of performance where the individual can perform the skill fluently and instinctively and where outside influences do not affect the outcome. It may take individuals a long time to achieve this stage with many never reaching it. This may be due to the training demands, the complexity of the task or a lack of motivation. 75. Provide an example of how someone would progress through the stages of skill acquisition. An example of an individual progressing from the stages of skill acquisition would able to perform a certain skill without failure and loud have a skill as a second nature. 6. Describe the characteristics of a learner (personality, heredity, confidence, prior experience, ability) The learner brings many influence the capacity of the learner to acquire skills. Personality, heredity, confidence, prior experience, and ability particularly influence the direction of the learning experience. These characteristics influence the speed with which that person ma y acquire a skill. Personality: Refers to an individual’s characteristic way of behaving and develops as a result of infinite social interactions and learning experiences throughout life. From a motor learning point of view, certain aspects of personality tend to be favorable with certain learning environments for example elite coaches tend to select athletes not only with superior physical talent but also those who possess positive learning attributes such as determination, enthusiasm and dedication. Learners whose personality reflects positive ways of behaving are more receptive to instruction and advice, more cooperative in performing set tasks and more helpful in creating a productive learning environment. If they possess patience, a willingness to try new things, listen to advice and can co-operate with OTOH other team members and the coach, they are more likely to have a positive outcome from a skill learning experience. If however an individual loses patience easily, cannot accept advice or cannot share experiences with others they will be slower in developing their skills. Heredity: Refers to the genetic characteristics inherited from our parents. These are unchangeable and limit the dimensions of our potential. The environment determines if we can reach the limits set by heredity. Specific hereditary characteristics influence the potential for success in specific ports/skills. Confidence: As an individual begins to learn skills and experiences success, they begin to develop a sense of self-belief in their ability to perform. Some level of confidence is internally generated, based on how the learner sees themselves (related to their personality). This confidence will then pass into the next level of learning. By learning and performing skills from a simple to a complex level, confidence will rise as the individual is more likely to experience success as they develop their skills. If however, they are given complex tasks early in their placement and they experience frequent failure, confidence is more likely to fall, which may slow down improvements in the individual’s skill level. Prior Experience: If an individual has participated in an activity which involves similar qualities, such the hand/eye co-ordination found in hockey, they may be able to learn the skills involved in other sports such as cricket or golf more effectively. It can also be seen between sports such as basketball and netball, and gymnastics and diving. Ability: Ability is the ease with which an individual is able to perform a movement or routine. We often all these individual’s gifted or talented as they often show ease and precision when executing a skill. Ability can also be seen in the way in which an individual is able to learn process and implement new skills. Ability incorporates a range of factors, such as sense of acuity, perception, reaction time and intelligence, which combine to allow the individual to do readily what is intended. 77. How can the physical environment affect the skill acquisition? The physical learning environment can have a positive and negative impact on the learning process and is a major factor in the development of skills. The learning environment refers to everything outside the learner, including the weather, the skill itself, the situation it is practiced in, and information from coaches. 78. How can the nature of the skill affect skill acquisition? Stability of the environment (open or closed skills) the precision of the movement (gross or fine skills) the distinctiveness of the beginning and end points (discrete, serial or continuous skills) Timing (externally paced or self-paced skills). 9. What is an open skill? Close skill? Gross Motor skill? Fine motor skill? Extremely paced? Internally paced? Continuous skill? Discrete Skill? Serial skill? Examples? Open Skill: occurs in an unpredictable and frequently changing environment (weather, field, opponents) where the timing and the placement of the performance are dependent upon factors outside the con trol of the performer. Performance of the skill is greatly influenced by external factors and as such most open skills are externally paced. The unpredictability of the environment forces the performer to respond in a variety of ways. Close Skill: occurs in a stable and predictable environment, where the timing of the skill is self-paced and to a large extent, the reformer determines the place where the skill will be performed. Gross Motor skill: involve the use of large muscle groups (arms and legs) and include such things as walking, Jumping, running and kicking. Fine Motor skill: involve smaller muscle groups and fine movements, such as catching a tennis ball, playing darts and positioning the hand and fingers during a dance performance. Extremely Paced: where the factors external to the performer set the time of execution of the movement. Rhythmic performances such as gymnastics, dancing, and aerobics, are externally paced as the movements must be performed in time with the music. Internally Paced: where the performer determines the time and pace of execution. Examples include serving in tennis and a corner kick in soccer. Continuous skill: A continuous skill is one that has no real beginning or end but is maintained in a repetitive fashion. The starting and finishing point of these skills are determined by the performer, not by the skill itself. This includes the leg action when running, cycling or swimming. Discrete skill: A discrete movement skill has a clearly defined beginning and end. It may include a throw or kick or a forward roll in gymnastics. Serial skill: this skill requires a number of separate skills to be performed in a specific order to achieve the set movement required. Activities such as bowling in cricket where a run up, a delivery phase and the follow through need to be combined for effective performance. 80. How are the relevant performance element incorporated into practice? For effective performance in game or competition, athletes need to be able to perform movements under pressure. Performance elements such as tactics, strategies and team plans need to be part of skill practice to enable optimal performance. Egg. Decision making strategic and tactical development Decision making: Athletes need to make many decisions that will influence the quality of the performance. These include decisions such as who to pass to, whether to shoot for goal or pass, or decisions to accelerate in a cycling or distance running event. Coaches need to provide opportunities for decision making in practice so the athlete can improve their skills resulting in clear decisions when performing. Strategic and tactical development: Some sports have a high strategic and tactical component. In tactical sports such as basketball, touch football or cricket, the learning environment just reflect the game situations to develop players understanding of how to with game play are can be similar across some sports, such as moving into space or marking a player. Athletes can develop an awareness of the tactics required and apply these skills in a variety of game situations. Tactical development requires practice of pressure situations similar to a game, rather than stationary practice or drills. As tactical development improves, game like practices can become more complex allowing for development of decision making and problem solving. 81 . What are the 4 types of practice methods used to learn skills? The 4 types of practice methods used to learn skills are massed, distributed, whole and part. 82. Describe each, giving examples. When would each be best used – for what types of skill and/ or types of learner? Massed: Massed practice occurs when one skill is continuously practiced in a session with only brief rest periods or none at all. This may involve a variety of drills aimed at improving the one skill performed one after the other. Distributed: Distributed practice can follow one of two forms. One form is when a range of skills, for example soccer dribbling, passing, and shooting. The other is where one skill is practiced, either through a single drill or a variety of skill drills, and broken up by moderate rest periods. Whole : refers to practicing a skill in its entirety, such as a softball pitch, whereas the part method involves a skill being broken into smaller components and each subsoil practiced separately, such as a basketball lay-up. Part: involves learning a part before adding another related part. Many coaches use a combination of methods, where the whole skill is taught, and then if difficulties arise, the skill is broken down and taught as the part method. Regardless of the way it is initially learnt and practiced it eventually needs to be put into a whole skill practice and performance or the co-ordination of the parts cannot occur effectively. 83. How do instructions vary according to the characteristics of the learner? 84. What is feedback? Feedback is the process of providing a performer with information about the nature or result of their performance. The performer will receive information from internal and external sources which may be concurrent or delayed. 85. The sources of feedback are internal and external. Explain these. Feedback can come from internal ND external sources; it may be given at different times such as concurrent or delayed; and it may provide different information such as knowledge of performance and knowledge of results. Internal feedback information received from the senses as a result of movement or self-talk. This helps athletes develop a kinesthesia sense or feel for a movement which allows them to distinguish between a skilled or less skilled performance. For example, when passing a netball, the athlete feels the ball in their hands and is aware of the ball leaving the hand as they can see, feel and hear it moving through the air and being caught by another player. External feedback is information received from external sources (outside the body) such as the crowd or the environment. 86. The types of feedback are knowledge of results (KERR) and knowledge of performance (KIP). Explain each and give examples. Knowledge of results (KERR): suggests how successful the skill was performed, and comes from an external source. This could include a coach discussing the outcome of a performance with the athlete, an athlete seeing the ball drop into the basket from a Jump shot, or from score boards. If the skill execution is successful the athlete is aware of the need o repeat the performance. If results are not favorable, a change must be made to improve performance. Knowledge of performance (KIP): information received about how well a skill was performed. It may be internal or external. For example a diver may gain information from an external source such as video replay about the position of her body during a movement or a basketball may put up shot and feels the execution is incorrect resulting in the shot being missed. 87. The timing of feedback can be concurrent or delayed. Explain each with examples. Concurrent feedback: information received during a performance. This is most often internal feedback but can also be from external sources. This feedback allows for immediate correction of body position to improve results during the performance of a skill. For example, during a tennis serve, the server recognizes that their ball toss is off direction. This concurrent feedback allows the player to stop the serve and improve the toss, rather than continuing the serve and being forced into error. Delayed Feedback: information provided to the athlete after the skill has been performed, and is therefore received too late to produce a response at the time. An example of allayed feedback is a comment from the coach at the end of the activity, at half time or from video analysis after the game. This information allows for changes to technique in future performances. 88. How is feedback used as learner’s progress through the stages of skill acquisition? Feedback is an essential component in the successful acquisition and development of skills, regardless of the stage of acquisition or age of the learner. Feedback provides information about the performance that allows the learner to adjust and improve or continue efficient performance. 89. What are the characteristics of a skilled performer? List and briefly explain what they mean? A skilled performer demonstrates characteristics and abilities which allows them to perform consistently at a very high level. Kinesthesia sense: Kinesthesia refers to the sensory information received from the body about their body position and awareness of limbs during a movement. A skilled athlete’s neuromuscular pathways are trained to ‘feel’ the movement resulting in better coordination and greater ability to make corrections and modifications while executing the movement. Anticipation: A skilled performer is capable of predicting hat might happen next, by reading cues, and choosing the appropriate response to the action. This gives skilled athletes an advantage over other performers as they can position themselves in preparation for the next phase of play to counteract an opponent’s move. Anticipation is particularly important in externally paced activities or where fast movement and decision making is required. For example, by watching the ball from the bowler’s hand, a skilled cricket batsman can anticipate the bounce shot. Consistency: Skilled performers demonstrate greater consistency resulting in fewer errors during a performance. An unskilled athlete may occasionally ‘fluke’ a good performance whereas a skilled athlete can perform well over and over. Skilled performers have progressed to the autonomous stage of skill acquisition, resulting in an automatic performance of skill. Unskilled athletes make gross errors frequently and rely on external feedback to correct these errors for future performances. Skilled performers use internal feedback and knowledge of performance. Thus they correct small errors during performance to demonstrate greater consistency and efficiency. Technique: Skilled athletes tend to maintain correct technique despite fatigue or the name situation. They have developed their skills to be fluent, smooth and well performed. The movement is more economical, will not use as much energy, and is phonemically correct and therefore less likely to cause injury. Mental Approach: Mental approach is the ability of an athlete to control their mind as they work towards a movement goal. Skilled athletes are able to achieve this through goal setting, visualization, concentration and focus. They are often more competitive, ambitious, confident and committed than unskilled athletes. They are more capable f controlling anxiety and arousal resulting in optimal performance and reduced errors. They are able to perform skills as part of complex movement pattern and strategic play while making complex decisions. The mental discipline of an athlete becomes increasingly important as they move towards the elite level in their sport. 90. How do we recognize a skilled performer? A skilled performer is often stronger, more flexible, better coordinated, balanced and fitter than unskilled performers. They are able to perceive, decide and act in a manner that is efficient in terms of both energy and time. 92. What is subjective appraisal? Examples? How to cite How can nutrition and recovery strategies affect performance, Papers

Travel and Don George free essay sample

The writer, Don George, gets a surprise every time he travels. Even though he has been a certain place before, he still gets surprised. He calls travelling his â€Å"mental picture-puzzle of the world†. The reason he has been travelling around the world was because he would like to understand everything by experiencing it. After some of his first trips, he got a job as a travel writer so he could continue travelling and writing about it. Now Don George has a daughter which globe he uses to point out how many countries he has travelled to – which is more than sixty countries. As he travels he keeps on gathering more pieces to his picture-puzzle. He believes that the travels bring him closer to God. Don George ends up believing that maybe the puzzle is God and all his travels and learning’s are incantations, prayers and koans. He thinks that the best thing we can do in life is to learn the things into ourselves and then give it back to all the new places and new people we encounter. We will write a custom essay sample on Travel and Don George or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page If you keep travel and live enough, you would contain everything inside you. Travelling For me, travelling are many things and it can include recreation, vacation, tourism and many other possibilities. Travelling for me also means stepping out of my comfort zone. It means expanding my horizon, literally and figuratively. I’m also very amazed and surprised every time I travel. There are so many different cultures and people have so many different traditions. I always learn something when I travel. I can chose to let it slip away or I can choose to take my experiences and learn it into myself. It’s about challenging the things I thought I knew. Travelling is lying down at the pool relaxed with a cold drink, it? s feeling welcome somewhere, even if I don’t know anyone. Travelling means taking my camera with me everywhere I go. Travelling is walking so much that my feet hurts but you keep saying to yourself â€Å"there are so much more to experience†. I don? t have to go to another country to experience something new. Travelling can be local, regional or international. It doesn’t matter where I am in the world, I will always come home with new wisdom. But travelling can also be something else. I live in a small provincial town where the possibilities for youngsters to experience and get educated are limited. After I’ve graduated high school I would like to move to Copenhagen to study. For me, going to Copenhagen to be educated and live there would be a travel. Frederikshavn and Copenhagen are from my point of view totally different. Even though I’ve been to Copenhagen many times, I still see it as a travel. I can go there as a tourist, I can go there to be in a tournament, it can be a business travel or I can go visit my family and friends. And if I lived in Copenhagen I would travel around the city experiencing, learning and seeing new things everyday. For me traveling can also be boring. Travelling by train, bus, plain, ship, cars such as public transport can be a downside. I don’t like to sit in a train for several hours getting bothered by the person besides or in front of me talking about the party the have been to or about their grandkids or asking me a thousand questions – Jesus am I going to hear your ignorant voice for five more hours? Besides that I absolutely love to travel. It doesn’t matter if it’s near me or far away, whether the climate is cold or warm, it is about living and learning. Soon I’m travelling to USA for two weeks, I can’t wait to experience the culture and the pulse of the land of opportunities. The best times in my life has been while travelling, alone, together with my family, with friends, classmates or my teammates. So the wise words of the great Danish author – Hans Christian Andersen: â€Å"to travel is to live† are 5 words covering my attitude to travelling.

Compared to the original Daniell Cell Essay Example

Compared to the original Daniell Cell Essay Example Compared to the original Daniell Cell Paper Compared to the original Daniell Cell Paper By completing and testing this hypothesis our group believes that it will factor in the aim of increasing the voltage and current of our Daniell Cell. Hypothesis 2 According to the Standard Reduction Potentials for Half-Reactions table, our group hypothesises that by changing the half cells so that their E0 values are a greater distance apart that the voltage and current will show an increase and improve the Daniell Cell. The general make up of a Daniell Cell is two half cells, one with copper metal (Cu) and the other cell using zinc metal (Zn). The electrolyte then is both sulfates of each metal, CuSO4 and ZnSO4 making up the Cell. According to the Standard Reduction Potentials for Half-Reductions (SRPHR), Copper and Zinc is a good pair since Copper is a fairly strong oxidizing agent and Zinc is a very good reducing agent which gives a high voltage between these two half cells. Corrosion Doctors, 2006 The group has decided in changing one of these half cells to a better oxidizing agent or a reducing agent the voltage of our cell will increase and therefore support our hypothesis. Since this is a school experiment, it is very hard to access the best oxidizing agents, which has left us with Potassium Permanganate (KMnO4) as our best oxidizer and magnesium (Mg2+) as our best reducing agent. When both ionic concentrations (the electrolyte) are at 1M and the room temperature is at 25oC you can calculate the voltage of what two half cells would be by using the given E0 value. Copper has an E0 of +0. 34 volt and Zinc has an E0 of -0. 76 volt and you subtract the oxidizer from the reducing agent which gives 1. 10 V (volts). The calculations for the magnesium and potassium permanganate are as follows, potassium permanganate E0 value is 1. 52 and the magnesium E0 value is -2. 37 which gives 3. 89 volts. Under these conditions the voltage should increase from 1. 10 volts to 3. 89 volts, in which will support our second hypothesis. Hypothesis 3 After extensive research into different forms of salt bridges, our group believes that in using the porous pot salt bridge the decrease in resistance provided by the pot will increase the voltage and current readings of the original Daniell Cell. A salt bridge, in chemistry, is a device used to connect the oxidation and reduction half-cells of an electrochemical cell. It is also apart of the internal circuit of the cell with the external circuit being the wire that connects the anode to the cathode. Salt bridges usually comes in two types: glass tube and filter paper with other portable options still available. One type of salt bridges consists of U-shaped glass tubes filled with a relatively inert electrolyte, usually potassium nitrate. The conductivity of the glass tube bridges depends mostly on the concentration of the electrolyte solution. The other type of salt bridges consists of a filter paper, also soaked with a relatively inert electrolyte, usually potassium nitrate because it is chemically inert. Conductivity of this kind of salt bridges depends on a number of factors: the concentration of the electrolyte solution, the texture of the filter paper and the absorbing ability of the filter paper. Generally smoother texture and higher absorbency equates to higher conductivity. A porous pot or other porous barrier between the two half-cells may be used instead of a salt bridge; they give a much higher current flow since the resistance is much less which is ideal for this investigation. Chemistry Virtual Textbook, 2006 In the Daniell Cell the porous pot cell consists of a central zinc anode dipping into a porous pot containing the zinc sulfate solution. The porous pot is, in turn, immersed in a solution of copper sulfate contained in a large beaker, which acts as the cells cathode. The use of a porous barrier prevents the copper ions in the copper sulfate solution from reaching the zinc anode and undergoing reduction. This would render the cell ineffective by bringing the battery to equilibrium. Our group has hypothesised that using the Porous Pot as the salt bridge will bring upon an increase in voltage and current therefore making a Better Battery. Balanced Chemical Equations and E0 values Zn2+ (aq) + 2e- Zn(s) E0 = -0. 76 V Cu2+ (aq) + 2e- Cu(s) E0 = 0. 34 V Zn(s) Zn2+ (aq) + 2e- Cu2+ (aq) + 2e- Cu(s).

These five solutions were Zinc Sulfate, Copper Sulfate, Potassium Nitrate, Potassium Permanganate and Magnesium Sulfate. These five solutions yielded the property that meant they could be dissolved into water with Zinc, Potassium and Magnesium all forming a clear colour. Copper Sulfate forms a blue solution, whereas Potassium Permanganate forms a dark purple solution. Throughout the duration of the investigation students must wear safety glasses along with a lab coat to protect their skin from any contact with the solutions. Keep the experimental area clear of books and other items that may cause an incidence of spilling or breaking equipment. In an emergency situation, such as contact with the eyes and skin, the patient must flush and wash away the solution for fifteen minutes and remove all contaminated clothing. If large amounts of any of these solutions are ingested do not induce vomiting and call for a physician immediately. Conclusion and Discussion In relation to the first hypothesis the results have supported what has been stated. From an in depth study of both the Nernst and Le Chatelier principles the hypothesis was made that by changing the concentration in the cathode and keeping the anode at its lowest concentration will show an increase in current compared to the original Daniell Cell. The average of the Daniell Cells voltage and current was 0. 97 volts and 0.22 mA, then the concentration in the cathode and anode were increased and decreased giving positive results. When our hypothesis was tested the current, as expected, increased vastly going from an average of 0. 22 0. 50 mA by just changing the concentration. As well as the current the voltage also increased slightly going from 0. 97 1. 11 volts. This can be explained by using Ohms Law which is: which can be said as; when increasing I (current) as long as the resistance stays the same the voltage is also going to increase. The second hypothesis was once again supported by encouraging results. In this case both the cathode and anode were getting changed at different times in hoping finding two half cells that gave the best voltage reading. The anode was changed first and by doing this the group achieved an improved reading, to complete the hypothesis the cathode was then changed which meant the new battery was using the two half cells that were the furthest away from each other that could be obtained in classroom conditions. The Daniell Cells starting voltage was 0. 97 volts and when using Carbon + KMnO4 0. 02M as the cathode and Copper + CuSO4 0. 1M as the anode the reading we received was 2. 84 V which was a much better results to the original Cell. Le Chateliers Principle can be used to explain the decrease in voltage (compared to the redox table) in the results involving these two half cells. Since the concentration in the cathode is lower in contrast to the anode the shift in equilibrium is towards the anode which then causes less of the solution used giving a lower voltage. The current was increased by 159. 1 % which then can be clarified by Ohms Law which says that when increasing voltage the current will also increase when the resistance is kept at a constant. The third and final hypothesis was in relation to the changing of the salt bridge which was hoping to bring about a change in the current flow. The group only tested one other type of salt bridge due to time constraints which proved very effective. The porous pot was a new type of salt bridge which caused the internal circuit to be much more efficient and also make the battery portable. The current reading given by using the porous pot salt bridge was far better then the group expected, going from 0. 22 mA 27 mA (12172 % increase) which was a very pleasing result firmly supporting our hypothesis. The voltage also showed an improvement of over 11 % which shows strong support again to our hypothesis. Therefore our Super Cell was able to be formed by observing these result tables. Since the aim of this investigation was to find the best battery with the most current and voltage these changes must be made. The two half cells have to be as far away as possible on the redox table to cause the highest E0 value or voltage. The salt bridge that must be used is the porous pot as it provides a very high current reading and causes the battery to be more realistic as it will be portable. The last change is that the cathode must have the highest concentration for an extra increase in current. This factor was not testable for our super cell as the only concentration for the MnO4 was 0. 02 M Our Super Cell is then as follows Mg(s) + MgSO4 (0. 1M) MnO4 (0. 02M) + C(s) Using Porous Pot soaked in KNO3 Voltage = 3. 0740. 001 V (216. 91% difference) Current = 1191 mA (53,990% difference) These results show the vast improvement of the new Super Cell compared to the original Daniell Cell. The aim has therefore been attended to and completed and all three hypotheses have been supported with compatible results. Evaluation Although the results received were very positive and back up all hypotheses there were many limitations and errors that could have been taken care of in the future. The external circuits or the wires connecting each half cell almost all had rust on them which acts as a resistance causing a reduced voltage and current. The rust was also not consistent on each set of wires, which meant when the group used different wires the voltage and current readings differed each time. The volt and ammeters were very inaccurate at times and most of the time not giving a current reading which meant there was less time to carefully finish each experiment which then caused more inaccuracy in the results. Another error which occurred due to equipment, which was unfortunately unavoidable, was each of the solutions used. After each reading was taken we were to pour the solutions back into their containers. The solutions may have been contaminated whilst the cell was operating and as the solution was then poured back into the original container the contamination spread. This would eventually decrease the concentration of electrolyte and as such change the data, decreasing the voltage and current. To fix this error, the solutions should not be poured back into the containers again. Another error was the lack of trials within the experiment. Due to time constraints we complete the desired number of trials for each hypothesis. It is desirable to have as many tests as possible, one trial to establish the basis while the others are trying to be as accurate as possible. By not having a complete number of trials we limited the results that have been found. If we were able to complete more trials, we would have been able to have a fairer and more accurate result. We would be able to overcome this by having a longer time to conduct our trials. This would have given more time to be more precise with the work that was completed. A different filter paper salt bridge should have been used each time testing, since when used once the paper soaks up the electrolytes of each half cell which becomes inexact next time its put into use. The filter paper also dries out after a while which reduces the current of the cell, making the experiment more inaccurate as time progresses. The group was only provided with 0. 02 M KMnO4 which then forced us to not put one of our hypotheses into use in creating our Super Cell which was having the concentration in the anode lower then the concentration in the cathode. Another error was the use of Carbon as the inert metal in the KMnO4 solution. Since Carbon is not completely inert the current was unable to flow, free of resistance from the Carbon, therefore reducing the current reading of the cell. The magnesium metal was also an issue as it tends to oxidise instantly with oxygen causing an oxide layer on the metal and also reducing the current reading of the cell. Further investigation could possibly be to test many other hypotheses such as the surface area of the metals to make our results more thorough. More electrodes could have been added to the half-cells. This would create a cell with a larger surface area in which the reactions would take place. This would then allow a larger current and voltage as there would have been more electrons to create a higher current. There would have been a larger amount of area in which the electrons would be able to be taken from. The larger the surface area, more electrons are able to be attracted to the electrode, consequently producing more voltage and current. Russian Chemical Views, 2009 Cutting edge battery research and development have allowed improvements such as changing the metals in the half cell to still make it more efficient eg. Lithium. Lithium-ion batteries are incredibly popular these days. Theyre so common because, pound for pound, theyre some of the most energetic rechargeable batteries available. Lithium batteries are disposable batteries that have lithium metal or lithium compounds as an anode. The term lithium battery comprises of many types of cathodes and electrolytes. The most common type of lithium cell used in consumer applications uses metallic lithium as anode and manganese dioxide as cathode, with a salt of lithium dissolved in an organic solvent. (Brain, 2008) Improvements such as the electrodes being further apart in the redox table, eg lithium and silver would have been able to create a higher voltage. Again this is a problem because it is very unsafe as lithium is so reactive that it will react with the oxygen in the air. Therefore it may not be possible to create a Daniell Cell out of those materials. Further research into looking into ways of creating more reactive yet stable electrodes we could create a cell which supports the claims of the Redox table but is also able to be completed within a class room environment.

Boss Personal Statement Example | Topics and Well Written Essays - 500 words

Boss - Personal Statement Example Although management and leadership are not utterly different, the two concepts may not be the same either. There are many ways in which management differs from leadership, especially when looking at the differences from leadership skills and management skills. Leadership emphasizes more on vision of the project than implementation. On the contrary, management entirely focuses on implementation and vision is second guessed. Further, leadership takes a keen interest in situation dynamics; these dynamics provides the leadership with hints on the right action to take. Leadership makes attempts that alter the culture in order to attain the best results that benefit the majority. On the contrary, management focuses on techniques and it does not advocate for changes. Rather, management strives to maintain the status quo and order in an organization, as well adapt to the traditions. Furthermore, leadership focuses on risk taking and positive possibilities while management worries so much of the negative consequences, which might result from an action. Finally, leadership aims to rebuild and reshape an organization to ensure that the organization moves towards the vision and objectives. It does this through the employment of persuasion skills, as well as possibility ideas. These actions do not take any consideration of the position of the organization. On the other hand, management focuses on achieving the prescribed organization and it adopts attitudes and behavior according to position or level. Management does not disclose information and knowledge to workers; they fear that their own position might be compromised by information leakage. There are many characteristics of good leaders, which can take time and space to discuss.

Retail Park Assignment Example | Topics and Well Written Essays - 2750 words

Retail Park - Assignment Example Major business brands would be attracted to a retail park thus giving consumers a much wider range to choose from. A retail park can also use brown field sites, if they are small. The use of a brown field sites would mean that acquiring of land, residences and other structures for building of the retail park would not have to be done. And also new land would not have to be acquired for the building of roads and railways as the ones already could be renovated and used. Since Medway does have problems associated with low wages, a retail park would create innumerable job opportunities for the people of Medway. Also, retail parks would provide opportunity for unskilled and low-skilled people to earn, thus addressing Medway's problem of lack of skills in certain areas. Having a retail park will lead to developments in social and economical infrastructure. This in turn will increase Medway Town Council's revenue. Thus the area surrounding the retail park will develop, and more people will come and settle in the area. First the demand for labor increases as shown by then rightward shift of the curve DI. Thus the wage rate increases from W to W1. Next the supply of labor increases in response to higher wages and a new supply curve marked S2 shifts on to the right. Ultimately the equilibrium wage rate is established at W2.However the serenity of the sub-urban country side of Medway could be lost due to the setting up of a retail park. Thus there is likely to be opposition from the environment conscious local communities. Preserving the country side should be of high priority. Due to the increase of traffic and the development of commercial infrastructure such as airports and offices there would be sound and air pollution. The Medway council would have to think of a way of disposing waste products from the retail park (Needham, 2006). These waste products could flow to the rivers and canals in the vicinity thus giving rise to water pollution. Certain species of birds and animals endemic to this area could be driven away as a result of acquiring land to set up the retail park. This could lead to protests from environmentalists. One of the major economic effects of the proposed retail park would be on the local shopping centers in Medway. The first major issue of an out-of-town retail development is the loss of business by the local shopkeepers. Acquiring land and the demolition of existing buildings would mean that the Medway council would have to pay compensation to the property owners and relocate them. The Medway council would have to bear this cost. Money will have to come from banks at high interest rates for this purpose. In order to have ample parking space, a large area of land would has to be rented. This will cost a considerable amount. Scenario A-2 Medway, which is located 30 miles East of London and 40 miles North West of Dover, is one of the largest

Human Resource Management at McDonalds

Human Resource Management at McDonalds Human resource management is the basis of all management activity, but it is not the basis of all business activity. The basis of management is always the same: getting the people of the business to make things happen in a productive way, so that the business prospers and the people thrive. Torrington et al (2005:4) Human Resource can be say to be the strategic and coherent approach management of an organisations most valued assets. The people working these individually and collectively contribute to the achievement of the objectives of the business. Human resource is one of the important parts of any organisation management in the 21st century and up still date. Any corporate firm can get competitor advantage by human resource. The term Human resources can be viewed in two contrasting ways. Placing emphasis on the word Human implies that an organisations assets are valuable human beings with feelings and aspirations that should be respected and nurtured. Highlighting the word resource may have the effect of devaluing the human element by relegating people to a mere resource that is to be deployed as effectively and efficiently as possible, like a piece of machinery. These associated have been embodied as soft and hard HRM (storey, 1992). Soft HRM is often associated with quality-enhancing and value-adding measures, whereas hard HRM is linked to cost-cutting and cost minimization strategies (Schuler and Jackson, 1987). Importance of Strategic Human Resource Management Strategy human resource management is very important because it help to resolve the problems that affect people management programs in the organisation. In every organisation, the employee and customers are very important and the try to listen to their employee and resolve whatever complains from them or the customer.

The key feature where the two ideas are connected is that they are precisely in approach toward people management. BRIEF HISTORY OF MCDONALDS McDonalds started as a burger brand in 1940 and it was formed by two Brother Richard and Maurice McDonald in San Bernardino, California. It progressed from a hotdog stand into one of the worlds leading restaurant chain. By 1953, McDonalds brothers began franchising their restaurant and the first was taken by Neil Fox who opened in other parts of California. McDonalds Corporation came into existence in 1954 after an entrepreneur and milkshake mixer salesman Ray Kroc acquired the franchise of McDonalds outside California after which he bought the business rights from the McDonalds brothers for $2.7 million in 1961. By 1974 the first restaurant in the UK opened and 1988, they had opened in the communist country in Belgrade, Yugoslavia later in Moscow, China and India. In 2003, the Im loving it campaign was launched and by 2005, McDonalds started a Mc Delivery service in Singapore. McDonalds has been looking for a growth strategy for a very long time. And their foreign operation amount for more than half the companys revenue. McDonald has over 30,000 restaurants over 100 countries in the world today. And they maintain the top position in the fast food industry for the past 50 years. Amongst the award bagged by McDonalds is the Catalyst award for its program for fostering leadership development in women and McDonalds has been backing the summer Olympics since 1984. Business strategy of McDonalds in the UK Employment planning: McDonalds try to make the right plans in employing the right number of staffs that the organisation need at the right time. This is the process by which the organisation attempt to ensure that it has the right number of qualified people in the right place and at the right time. Selection: McDonalds involves in choosing from the available candidates the individual predicted to be most likely to perform successfully in the job. They select but the skills and unskilled individual and try to train them in other to make them understand the objective of the organisation. Selection is not always the best process of employing staffs in the organisation because skills will be lack. Training: McDonalds also used the training strategy to improve and develop the skills of the workers in the organisation. Although training is very important in most organisation but its better to bring the right people with the right skill and then give them the right training so they will understand better and know the objective of the training. Education: The management of McDonald provide education for some staffs that are really willing to retain in the organisation. This education is to improve their performance and to give them more ideas about the economic and how the business is operating. Performance: The Company always chose a right time to check the performance of their workers. The performance of the worker can help the company to make the right changes at the right time and the right department of the workers. These has help MacDonald to build a better services. Pay: Macdonald is a big restaurant with so many branches around the world and helps to reduce the unemployment around us. The Company give a good pay to their staffs and encourage them to work. Staff retention: Macdonald tries to keep their staffs and give them promotions to enable them become a manager of a branch someday in the future. Staff retention is very important to most organisations. This will help the staffs to know what really is happening within the organisation and try to suggest a best opinion to fight that out. Contribution of Strategy Human Resource in McDonald Staffing- McDonald should try to get people with the appropriate skills, knowledge, abilities, and experience to fulfil the organisation objectives. Rewards McDonald need to give reward to the staffs who work very hard in development of the organisation. Employee development- the organisation should also help in developing the staffs through providing training and knowledge for them in other to perform a good job. Employee maintenance- maintaining staffs is important in the development of the company. The administration is should try to encourage the staff and reward them in the good job done. Many organisations try to establish why people leave by conducting exit interviews but these are rarely sufficiently accurate, as many people will not give the full reason why they are leaving for fear of jeopardising future reference requirement or because they may wish to return to the organisation at some later stage. There organisation should make sure they try to maintain and look after their staff in other to keep them happy. Employee relation McDonald should develop the relationship between the staffs and the management in other to bring up a smiling environment within the work place. CONCLUSION McDonalds is seen as a global restaurant offering a range of products in a highly competitive and fragmented market. The company must positively respond to both internal and external issues to avoid losing sales and market share. They have been able to achieve a broad scope of business activity as they adopt the cost leadership strategy. There offer food prepared in the same high quality manner worldwide, tasty and reasonable priced delivered in a consistent low key and friendly environment. The opportunities and threats present in the environment enables managers to look both internally and externally to direct their strategy from the information given as it allows them to know their weakness and guard against them as well as make use of opportunities available to them. SHRM NEW MANAGER IN MCDONALDS As the manager of McDonalds, the percentage of highly skilled labour/ talent recruitment will be increase, but low skilled will be reduce as they are the ones directly involved in preparing food and serving customers. Human resource strategy in McDonalds encourage employee involvement and engagement to improve customer service but recruitment and selection in McDonalds is of little emphasis as the nature of the job is mechanical hence most of their recruits are fast learners who can learn on the job rather quickly. There is a rare case of training and development of staff as they are low skilled and the need for the need for developing them would not be beneficial to the corporation. The strategy of McDonalds is based on concept of Michael Porters differentiation and low- cost leadership as their products are mass produced and cost can be reduced by doing this, the threat this can cause is that its competitors like Burger King and KFC can also mass produce at a low cost. Differentiation can be described as marketing technique used by a McDonalds to establish strong identity in the restaurant business. It can also be called segmentation strategy. In McDonalds, there is a huge number of unskilled labours whose employment contact are mostly on short term basis, hence the need for a huge pension budget will not be necessary, this will be seen as an opportunity for the corporation to save revenue. Also in areas of training and development, since they train on the job and there is no series of further training carried out, the corporation does not lose skill and revenue when such employees decide to terminate their employment.

Statues of David Essay -- essays research papers

There have been many staues of David sculpted by famous artists like Donatello, Verrocchio, and Michelangelo. Bernini’s version of David and is about to begin his attack on Goliath, as he appears posing. The statue seems to be moving through space and the action suggests that the action of flinging the stone requires a lot of room around David. The statue forces the observer to look past the actual subject and focus more on the surroundings. He seems to have very muscular legs, and appears to be ready to turn and throw a stone from his sling. This is the most dramatic pose that Bernini could have picked and was chosen because it shows a sudden burst of energy and a moment of suspense as well. Bernini’s David is different from that of other artists because there is an expression of concentration that makes the statue a more imposing piece of artwork.   Ã‚  Ã‚  Ã‚  Ã‚  Donatello’s David was created for the courtyard of the Palazzo Medici. The statue takes on a different pose, and was one of the first free-standing nude statues of the ancient world. l when compared to Bernini’s, it is more classical. Bernini’s rendition is posing and relaxed like a Greek god would be. Donatello made the ancient Greek style popular during this time. Donatello’s David has long flowing hair and has one of his legs placed firmly on top of the head of Goliath, representing his victory over the behemoth. He portrayed David as the slayer of Goliath and as a symbol of the independent republ...

buy custom American Culture during the 1820 and 1830s essay

buy custom American Culture during the 1820 and 1830s essay In the 1820s and the 1830s, America faced the era of democracy and era of eradicating slavery. During this period, America experienced the niche of democracy and there it involved national politics. In terms of democracy, the most prominent thing that was being addressed was the issue of slavery and the way it could be abolished from the system (Holt, 1983). Artists like Harriet Beecher Stowe advocated for a non-slavery culture; she wrote about the accounts of abolitionists and slavery in her book Uncle Toms cabin. This brought about the abolitionist transformation. In 1831, William Lloyd Garrison started publishing The Liberator, an abolitionist newspaper dedicated to equality for all Americans including the African Americans (CliffsNotes). There was radical abolition movement that was meant to eradicate slavery. Many historians were included in this era that included Robert Abzug, Richard Blackett, Aileen Kraditor among others. These fellows brought about the changing culture of America accepting African Americans as equal, and tried to eradicate slavery (Green, 2009). In this time, there also emerged a movement called Young American Movement, which was led by Stephen Douglas. The movement was meant to embrace and enhance commerce, technology, and internationalism. Through the combination of these two facts, the America became a great success. This culture brought about the Lincoln- Douglas debates. Lincoln said that the US could not be divided more to success as a half slave and half-free state (Johannsen, 1965). This would not bring up the economic success that the country needed. In this era, the need for democracy emerged, an activity termed as American Renaissance came to existence. It involved usage of newspapers, magazines, and communication articles to portray democracy. This was tested by poets like Whitman and Emily Dickinson; they used unrhymed and off rhyme verses to portray their messages. Most of the themes that they put on their articles were for slave liberation and economic enhancements. Buy custom American Culture during the 1820 and 1830s essay

Jon D, Rockefeller essays

Jon D, Rockefeller essays John D. Rockefeller created the empire of Standard Oil.

After Rockefeller left his job as a bookkeeper in 1859 to seek his own fortune, he joined forces with an Englishman named Marcie Clark. They formed a business as merchants in grain, hay, meat, and other goods. Taking advantage of the extra business that the war gave them, the firm flourished .

Rebates were given as a bonus for giving the railroads big business.{ "The published rates were charged to smaller independent businesses and a lower unpublished rate was charged to big suppliers."} In addition to this price break, the big firms were also given part of the higher prices charged to the smaller companies.
