The Use of Urinary Catheters in the Nursing Field Annotated Bibliography - 11

The Use of Urinary Catheters in the Nursing Field - Annotated Bibliography Example The article provides substantial statistics on the annual estimate of patients who end up being subjected to catheters. Its objective is to evaluate the prevalence and appropriateness of the use of catheters in the region. The article is fundamental because of its ability to examine the measures that should be considered before application of unnecessary catheters to patients. The context also outlines some of the challenges that are associated with the use of these devices. NHS Choices provides readers substantial content on the reasons why catheters are used. The various types of catheters, their risks as well as giving a well-detailed explanation of how patients can learn to live adequately with such conditions.T he articles’ ability to be all inclusive of the necessary knowledge on catheters makes it stand out. The kind of content in it is of a high quality hence I chose to use it to construct a source point out of it. From this abstract, the author is revealing the fact that in health care facilities, a urinary catheter is the most common infection that is caused by the attribution of the indwelling urinary catheter. The period that is taken by the catheterization determines the significant development of the biofilm. In acute healthcare facilities, more than 50 percent of patients that are taken care of in a prolonged term is found to have acquired the bacteria. The writer suggested that this infection will reduce if the use of an indwelling catheter and if it has to be used, it has to be in a technical way. According to the abstract, it highlights that male catheterization is a skilled procedure that needs an experienced expert.

Physical fitness Cardio-vascular endurance

Physical fitness Cardio-vascular endurance Fitness components in sport Health related components Cardio-vascular endurance Cardio-vascular endurance is how the body supplies oxygen to fuel the muscles when participating in sport or high endurance events and situations. It does this through the heart, blood vessels, blood and respiratory system. Footballers need cardio-vascular endurance when the play because they need to be able to run throughout the whole 90 mins. Oxygen to the muscles is what allows them to do this. Swimmers need cardio-vascular endurance when they do long distance races e.g. 1500m swimming race where their body need a descent supply of oxygen to the muscles from start to finish. Boxers need to have excellent c-v endurance to be able to compete at a strong pace throughout a fight. Their muscles need oxygen in order to work throughout a fight so that they can throw punch after punch and block after block. Both these motions need the muscles to contract, flex and tense. Muscular endurance Muscular endurance is the ability to perform repetitive or sustained muscular contractions against some resistance for an extended period of time. Muscular endurance allows athletes to do more strenuous work. Footballers need muscular endurance to be able to repeatedly use muscles throughout a match e.g. in sprinting a player uses the quads and caths over and over throughout the game. In swimming they use their muscles continually over the race e.g. in butterfly they use most if not all the bodies muscles to drag themselves through the water. Boxers need muscular endurance to be able to continuously throw punches from round one to round twelve because they need to be swinging away for the whole fight but if they cant then they wont be able to fight the whole twelve rounds. Muscular strength Muscular strength is the ability of an athlete to perform a sport at a sustained high tempo for a short amount of time. Footballers need muscular strength to be able to exert strength when they shoot the ball from a long distance so that it travels fast and with power towards their target. Swimmers use strength when they push of the back board after a length in order to start the next lap. This requires the use and strength from the quads, calfs and foot muscles for the push off. In boxing when a fight needs to dodge a shot they may use the tactic of leaning back to avoid the punch. This requires the use the abdominal muscles. These need strength to be able to support his upper body as he leans back. Flexibility There are two types of flexibility. They are static flexibility and dynamic flexibility. Static is when an athlete slowly stretch and hold the position for a period of time. Dynamic is when an athlete makes a quick movement in which they stretch. In football a goal keeper needs flexibility when he stretches for the ball e.g. when the ball is heading for the top corner. Swimmers need good flexibility to be able to stretch their arms out properly and have a good stroke length e.g. Michael Phellps showed good flexibility when he was waiting on the starting board by showing his arm span and stretching it to its relaxed max before the start of the race. Boxers dont really need too much flexibility but the one time they do need is when they lean back. They stretch the back throughout this movement. Body composition Body composition is the amount of fat, bone and muscle in the human body. Athletes need different body compositions to perform different sports. Footballers need to have a slim body composition because they need to be able to carry their weight around the pitch. If a footballer is fat then it makes it harder to run for long periods and also makes it harder to carry their own body weight. Swimmers need to be slim so that they can travel through the water faster and smoother. Depending on a boxers weight class a boxer needs to big and heavy or thin and light. This is so they can perform fairly at their weight class. Skill-related fitness Balance Balance is a skill that is naturally learnt after birth but can be developed further by an athlete so they can perform their sport properly. Balance is important because we must stay in a state of complete balance when performing are sports So that we dont fall over when performing. Some athletes need more balance than others. Footballers need balance when they shot. They put their arms into a supportive stance for when they hit the ball so that they dont lose their balance. Swimmers need balance when they are getting ready to dive in at the start of a race. A good balance can give them a good start allows them to get a head start. Boxer need balance so they can throw strong punches and put their whole body weight behind the shot also when they dodge shots they need to have good balance to enable them to recover into the stance quicker. Speed Speed is the quickness of a limb over a distance in time but it does not just affect the legs it involves all limbs and body parts from legs, torso to arms. Some footballers need to be fast this needs speed e.g. a winger needs speed because he is expected to run the lines to create the opposition with a problem. Swimmers need speed when they lash through the water to keep a good stroke per minute time. Boxers need speed when they throw a jab so that they can catch the opponent off guard and also so they can get out the way of any counter punches. Power Power is the ability to apply force quickly. A simple equation for power is: muscular strength X speed = Power. http://somatotype.net/nzfitness/pages/CompOFfit.htm . Power contains speed because in order to apply force you need speed. Footballers need power when shooting at goal. They need the quads and the calfs to gather up power on their way to the ball so that the shot can be harder and faster. Swimmers need power to be able to pull them through the water at pace e.g. when they do the freestyle they need to have fast, strong and powerful stokes. Boxer throw punch after punch, these punches need to be fast and power full so that they are unseen and effective e.g. a hook needs to be fast and power full so that the opponent does not see it and even if he does block the shot it will still hurt. Reaction time Reaction time is the time it takes for an athlete to react to a situation that is happening very quickly (The time taken to react to any stimuli). A goal keeper in football needs to have fast reacting times to be able to react to shots coming from 50yds to 2yds. Swimmers need to be able to react to the starting alarm as quickly impossible so that they are not left behind and can establish a lead. For boxers to be able to dodge in coming punches they need to react to the earliest stimuli and duck and swerve out the way. Agility Agility is the ability to stop and change direction or movement quickly. Footballers need agility because the game can change so quickly e.g. the goalkeeper blocks a shoot but the ball lands right in front of the goal, the player with best agility should react quickest and move fastest in order to defend it or strike it into the goal. Swimmers dont really need to be to agile but one place they do need it is when they are turning around for the next length because they need this switch of direction to be as quick as possible also being in water makes it harder because of the extra resistance. Boxers need to be agile unless they want to take hit after hit without getting out the way. When a boxer is be attacked by his opponent he will need the agility in his muscles to be able to move lightening quick to get out the way. Co-ordination Co-ordination is the ability to do something in a combination continuously. Footballers need co-ordination so that they can move the ball fluently between their legs because in football its not just putting on foot in front of the other it also about judging the speed of the ball and your own speed. Then when you shot you need to have placed your feet in the right places this takes co-ordination. Swimmers need co-ordination throughout a race. It quite easy but they need to co-ordinate when they should come up for oxygen so that they dont lose their speedy pace for example in the freestyle the swimmers have a number of strokes that they prefer to do before they come up for oxygen. This is all quite simple but if you lose your count and co-ordination then you can do too many stroke or too few and lose your oxygen pattern.

An Introduction To Fiber Optics Technology Essay example -- Technology

An Introduction to Fiber Optics Technology Throughout time, speed and efficiency in the telecommunications industry has progressed at a rapid pace due to fiber optic technology. In 1979, AT&T revolutionized the telecommunications industry by producing a medium for data transmission which used light, called fiber optic cable. This medium created a bandwidth of 44.736 Mbps and could multiplex 672 trunk circuits onto one fiber (Cole, 2000). However, this invention was only the beginning of a great addition to telecommunications, one that would change the industry forever. Even though AT&T introduced fiber optic technology in 1979, they weren't the first company to think of such a creative idea. The concept of exchanging data by the use of light was thought of by Alexander Graham Bell in the late 1800's. Bell always thought of possibilities that pulses of light could transmit voice signals, but Bell never had a dependable light source to test the idea (Cheo, 1990). In 1880, Bell patented a phone using optical transmission called the Photophone. Bell's invention failed because it used air as the medium to transmit light, rather than the glass fibers that are used today. Copper wire was simply more reliable than Bell's invention at the time, leading to the failure of his Photophone (Hecht, 1999). Expanding on Bell's idea, English scientist John Logie Bard and United States scientist Clarence W. Hansell patented the idea of using hollow glass pipes to transmit television images in the 1920's. However, the tubes patented were very poor quality and experienced signal loss very easily. Bard and Hansell also ran into the same problem Bell did, not having a constant, intense light source (Hecht, 1999). Solving Bard and Hansell's p... ...singly being used in every aspect of communications. When AT&T started using fiber optics in 1979, telephony was revolutionized. Today, the fiber optics industry is growing faster and faster. Over 90 % of long distance calls are now transmitted via fiber optics (Concise, 1994). Hopefully, someday there will be no limit to speed in the telecommunications industry because of fiber optics. Works Cited Cheo, P. (1990). Fiber Optics and Optoelectronics: Second Edition.

Obstacles Teachers May Face Essay

In any education setting, teachers will come across a wide variety of obstacles throughout their career. These obstacles will differ in each and every classroom, depending on students’ social, cultural and ethnic background. It is vitally important as a teacher to overcome these obstacles to ensure that the students within your class are able to gain the highest possible outcomes, a quality education and enjoyment from their schooling. Some of the many obstacles that a teacher may face in a classroom setting include development abilities both academically and socially, behaviour problems and unmotivated students. Students can differ from one another in several aspects, including age, mental ability, personal achievement, ethnic background, psychosocial development and cognitive development. These differences can affect how classroom learning happens (Snowman & Biheler, 2003). Children develop at different rates this is usually a result of different measures of intelligence, social interaction with peers and personal development. Whether it is physical, mental or emotional each student will differ, and this will also depend on their up bringing, prior knowledge, family circumstances and innate knowledge. Social and emotional development problems will result in the student finding it hard to create relationships and develop learning skills with his or her peers and educators. Intellectual development, communication and speech difficulties will affect student’s concentration, memory, communication and understandings of certain tasks (BTEC First Children’s care, n. d). As a result of children developing differentl, it is vitally important for educators to track and maintain an understanding of how each student is progressing through out the year, this will result in not only being of benefit for the student but also the teacher. According to Vygotsky, for the curriculum to be developmentally appropriate, the teacher must plan activities that encompass not only what children are capable of doing on their own but what they can learn with the help of others in group settings (Eggen & Kauchak, 2010). Therefore, by creating learning activities that are in learners’ zones of proximal development, and providing instructional scaffolding to support learning and development will accommodate the children by helping them gain a better understanding of the task at hand (Eggen & Kauchak, 2010). In saying this, this will ensure that the ducator is working to their full potential and ensuring that the students are getting the highest quality education. Positive reinforcement is the process of increasing the frequency or duration of a behaviour as the result of presenting a reinforcer. Therefore, offering positive reinforcement will increase and maintain the probability that a particular behaviour will be repeated. There are many different types of reinforcers that can be used to increase behaviours, but it is significant to note that the type of reinforcer used depends on the individual and the situation. While gold stars and tokens might be very effective reinforcement for a second-grader, they are not going to have the same effect with a high school or college student (Cherry, n. d). Also, if your students finish their work on time and have been successfully completing their work you may give them an early mark for lunch play, the students will eventually come to understand that finishing their work on time results in a rewards, therefore they will continue this behaviour. We all apply reinforcers everyday, most of the time without even realising we are doing it. You may tell your child â€Å"good job† after he or she cleans their room; all of these things increase the probability that the same response will be repeated. Students may find tasks hard to complete at school and want to give up, by giving them positive reinforcement twill encourage them to want to keep going. Students are more likely to be motivated to learn if they are positively reinforced for completing a project or task (Snowman & Biehler, 2003). Having a positive attitude as an educator and constant positive feedback also encourages students to feel secure in their learning environment. It can also be used to adjust behavioural issues, whilst punishment and negative reinforcement decreases unacceptable behaviour, it doesn’t teach desirable ones, in saying this; it means that positive reinforcement is more effective. However punishment is sometimes required in some circumstances, as when all forms of punishment is removed it can cause the class to become more disruptive. Research has found that some types of punishers are more affective these include; desists, timeout or detention (Eggen & Kauchak, 2010). Skinner believed that peoples innate needs, wants and desires can be avoided, as they alter their current behaviour according to what has happened to them due to the previous consequences of their past behaviour. He called this approach operant conditioning he identified three types of responses or operant that can follow behaviours, these include; Neutral operants, reinforcers and punishers (Eggen & Kauchak, 2010). Not sure of the reference? Having unmotivated students in the classroom can make it difficult due to the fact that other students may get distracted and lose focus. Unmotivated students have the ability to disrupt other students that can have a detrimental affect on the entire classroom and overpower teacher’s capabilities. There are many factors relating to the cause of unmotivated students in the classroom. These include behavioural issues and cognitive development. Students with learning difficulties may feel lost and confused by what is being taught and therefore give up on listening and trying. It is important to identify these students and put in place the appropriate means necessary to ensure that these students are understanding and motivated. Motivation is often classed in two different categories; extrinsic motivation and intrinsic motivation the difference being; extrinsic motivation is to engage in an activity as a means to and end. And intrinsic motivation is to be involved in an activity for its own sake. Eggen & Kauchak, 2010) Motivation is working towards maintaining and sustaining our efforts to reach a particular goal (Snowman & Biehler, 2003). In some classroom settings children display inappropriate or problem behaviours which can make it difficult for themselves and the students around them to learn, and also isolate the child from his or her peers (Child Study Centre, 2002). Therefore it is crucial as an educator to establish and maintain a classroom environment that will motivate students to learn. Having motivation to learn is essential for students to become successful in their learning. It is vital that students set both academic and social goals to work towards to ensure that both the student and the teachers are driving towards the same goal. According to Eggen and Kauchak (2010) motivated students have positive attitudes towards school, they describe school as satisfying, persist on difficult tasks and cause fewer behaviour management problems, process information in depth and excel in classroom learning experiences (Eggen & Kauchak, 2010). By creating a positive learning environment within the classroom, students will be encouraged to achieve and set learning goals to attain higher results. In a positive learning environment students feel secure and as a result are more willing to take risks with their learning. A classroom performance goal structure is characterised by the teacher emphasising student performance relative to normative standards rather than relative to the student’s prior performance. Features of this structure are the teacher’s provision of more public versus private performance feedback, and the valuation of correct answers over effort and learning (Hughes. , Wu & West, 2011). Through incorporating student’s interest into the lesson, relating lessons to real life and matching students abilities will help to motivate the students to strive for better results and develop a love of learning. Motivation within the classroom and a child’s need to succeed in their academic life is based on â€Å"Maslow’s hierarchy of human needs based on two groupings: deficiency needs and growth needs. Within the deficiency needs, each lower need must be met before moving to the next higher level. Once each of these needs has been satisfied, if at some future time a deficiency is detected, the individual will act to remove the deficiency† (Huitt, 2007). In conclusion, obstacles that teachers will face throughout their career are respective to each individual child and their differences when it comes to developmental ability, motivation and behavioural issues. Ongoing professional development is a necessary component in ensuring that an educator is properly trained in all areas. This will ensure that educator’s feel confident when an obstacle arises and the skills to be able to deal and respond to any given situation.. Therefore, incorporating a safe and happy classroom environment, ongoing professional development, understanding each individual child’s needs and backgrounds and motivating students will help overcome some obstacles that a teacher may face.

In what ways television affects Essay

AIM: I propose to find out what children say about how television affects their play. Socialisation is a very important concept in sociology and the role of the mass media is highly debateable. Many sociologists believe that media effects start by setting out an overall relationship between media and its audience. They are often called models of media effects. I will interview the children these interviews will be unstructured. The children will be interviewed separately. Gender will be a comparison I look at to and whether the gender affects whom the children imitate. CONTEXTS AND CONCEPTS: The study of Bandura Ross and Ross uses the term of social learning theory to assert that children copy behaviour another example of this is copycat violence found in Hagell & Newburn’s study. In my research will ask the children whether they say they act violently due to the violent content they may have viewed and whether they have chosen to imitate these programs. Hagell & Newburn’s study compared young offenders viewing behaviour with non-offending teenagers. They found the differences were few between the two groups and what they watched, with hardly any having seen the films that were causing the concern at that time. A few members of either group had an interest in a violent output. The young offenders had less access to different media types. Other factors instead of media could have been causing the differences in their behaviour. The other context being analysed is Bandura Ross Ross who looked at whether children learnt behaviour through observation. This is the idea of the social learning theory. Children were made to watch a violent model be aggressive towards a five-foot ‘bobo’ doll. Later the children were given an aggressive arousal and then taken to another room where they were monitored as to how they reacted towards the ‘bobo’ doll, after seeing a model do this. The different concepts are is copycat violence this is violence that occurs as a result of copying what is seen in the media. Catharsis another theory is the process where tension is relieved, for example violence on screen that provides a safe outlet for people’s violent inclination. The final concept is desensitisation some theorists argue that the constant media diet of violence makes them less sensitive to real human suffering. These concepts tie in with the idea children are passive sociologists believe this, children respond easily to everything. This is the reason for watershed on T. V at 9pm because what comes on television isn’t suitable enough for children and there is a fear that the children will imitate this behaviour. (337) MAIN RESEARCH METHOD AND REASONS: The method I will be using is by interviewing the children by asking them to explain the reason for their behaviour. The questions I will ask the children will be questions not only requiring the answers that I need but there will be a series of distracting questions so the children will not know the aim of the questions being asked. Interviews are an advantage because it is better to gather all the information needed for an interview because you get to understand what the interviewee’s true opinions are. Interviews are flexible and can be used in different ways; also the ethical advantage is consent of the participants the theoretical advantage is that at applies to the law of interpretivists (Action theory). You can use empathy to understand their opinions in depth; these methods generate higher levels of validity of these results. They give a general understanding of the problem, there is less pressure on the interviewee and their answers are more spontaneous. Important concepts are uncovered about the information that will help me conclude whether the children imitate what they watch. When interviewing the children I will be asking them which programs they imitate and this will give me an insight into whether there is a pattern with what they watch. The sample I will be using for the interviews are of children from the ages of five to ten years old, because at this stage of childhood where television will be their main interest and there is a large variety if television for children of these ages also this is the age children are most likely to be influenced by the media. The genders of the children being used are varied so I will be using five boys and five girls. The children all come from the Borough of Newham of East London. It is easier for me if the children are living in the same borough there will be an easier access to these children and it will be easier for me and the children. The sample of the children I will be studying is opportunity sampling as the sample depends on whether the adults agree to their children being in the sample. The consent for whether the child will participate will be the decision of the adults. In Bandura’s study he gave the children an aggressive arousal and in this study will not do this as the aggressive arousal means that the children could have acted violently because of the arousal given and not because they were imitating the models behaviour. (425) POTNETIAL PROBLEMS The interviews of the amount of children I will be looking at can be very time consuming. With this study I need to be aware that the sample isn’t appropriate enough to apply to the whole population because all the children are from the same background and all from a similar ethical background and there may be a pattern in their behaviour. The main practical issue is whether the adults will allow their children to take part in the study. These types of questionnaires are basically a conversation dominates by the interviewer. These unstructured interviews may also go off the initial idea of what is being interviewed. Also with the amount of children I will be looking at and the sample of children I will be looking at there will be a lot of activity so it may be difficult to record all of their behaviour. These interviews are more difficult to analyse, and there are less details provided on the concept being asked. Ethical problems are mental harm to the children if they don’t like the questions being asked of them. Right to withdraw will be an ethical issue also because the children may not feel they have the right to leave and stop asking the questions. The final ethical issue is informed consent, which will be coming from the child and not the parents. The children should be able to make the decision but when a child is involved the parents have the consent. Time consumption is a practical issue through finding time to interview ten children. Being able to get the children to understand the question and also to cooperate may be difficult. Likewise another ethical issue is the children may not understand the debriefing. If they don’t understand the debriefing there will be an issue of this ethical guideline and the parents will also have to also be debriefed too.
