Measurement and Instrumentation LVDT sheet Lab Report

Measurement and Instrumentation LVDT sheet - Lab Report Example The device consists of a primary winding (P) and two secondary windings named S1 and S2. Both of them are wound on one cylindrical former, side by side, and they have equal number of turns. Their arrangement is such that they maintain symmetry with either side of the primary winding (P). A movable soft iron core is placed parallel to the axis of the cylindrical former. An arm is connected to the other end of the soft iron core and it moves according to the displacement produced. The LVDT is also used as a secondary transducer in various measurement systems. A primary transducer is used to convert the measurand into a displacement (Scholey et al.,1995). The LVDT is then used to measure that displacement. Examples are: The graph above shows the plot between the resulting voltage or voltage difference and displacement. The graph clearly shows that a linear function is obtained between the output voltage and core movement from the null position within a limited range of 4 millimeter. The results showed that there is linear relationship between displacement and voltage and this relationship continues till the maximum displacement of 40 mm, after that output voltage was decreased drastically towards negative side. The results revealed that there is very strong repeatability in LVTD as show in fig. (2). There is almost no difference in output voltage when the experiment was replicated second time. These results are supported by the findings of other researchers who reported the similar results. (Tariq et al., 2002 ; Wu et al., 2008 and Drumea et al., 2006). It is evident from the data that the instrument has high sensitivity, resolution and repeatability. Maintains a linear relationship between the voltage difference output and displacement from each position of the core for a displacement of up to 40 millimeter. Scholey, G. K., Frost, J.

The Pre-Socratic Tradition and Socratic Philosophy Essay Example for Free

The Pre-Socratic Tradition and Socratic Philosophy Essay Socrates was one of the most relevant figures in philosophy. His influence in this field of discipline was so extensive that every philosopher who came after him followed in his footsteps. Though the history of philosophy considers Socrates as a central figure, there were lesser known but equally important philosophers who came before him. These individuals are known as Pre-Socratic philosophers. Now the philosophy before the time of Socrates and the philosophy that Socrates influenced shared similarities and differences. This essay seeks to discuss what makes these philosophies alike and what sets them apart. What was the pre-Socratic tradition all about? What was its subject matter? To properly describe the pre-Socratic tradition, there are several themes to consider. First, this tradition deviates from mythology and religion (Soccio 62). During the Greek civilization, the knowledge of the people was founded on either mythology or religion. The answers to their inquiries were provided for them by the stories of gods and goddesses. Pre-Socratic tradition relies on neither mythology nor religion. Second, its main preoccupations are nature and the world (Soccio 63-64). The thinkers before the time of Socrates were not satisfied with what was already established about how nature was or how the world worked. Instead, they posed their own questions on the workings of nature and the universe. Third, the pre-Socratic tradition used reason in their explanations behind the ways of nature and the world (Soccio 64). Prior to the emergence of these thinkers, the only explanations available were those which were mythological or religious in nature. As was earlier stated, the pre-Socratic tradition deviated from mythology and religion. This deviation is due to the preference for rational investigation. The pre-Socratic thinkers attempted to verify their views with reason (Soccio 64). These three themes define what the pre-Socratic tradition was about. There were many thinkers who were part of the pre-Socratic tradition. Three of these thinkers were Thales, Heraclitus and Anaxagoras (Soccio 64). All three pre-Socratics were preoccupied with discovering the ways of the world with the use of reason rather than mythology and religion. Thales was the first significant pre-Socratic thinker in history. He upheld the belief that water was the element behind all things. For Thales, every single thing in the world was created with water. He simplified the complex workings of the world into a single substance—water (Soccio 65). The conclusion that Thales had arrived at was not based on religious speculation or mythological presumptions. Instead, he created a rational explanation for what he observed in nature (Soccio 65). Just like Thales, Heraclitus also inquired about the world and the element which kept it together. If Thales believed it was water, Heraclitus thought it was â€Å"Logos† (Soccio 67). â€Å"Logos† is not actually an element per se; it was more of a principle. The word â€Å"Logos† itself has several meanings, but Heraclitus affirmed that it is the law which maintains everything and is contained in everything (Soccio 68). The Heraclitean â€Å"Logos† is the one responsible for the world order (Soccio 68). Lastly, Anaxagoras continues the tradition of the two aforementioned thinkers by proceeding with the inquiry about the cosmos. If Heraclitus believed that it was ‘Logos† which dictated the order of the world, for Anaxagoras it was â€Å"Nous† (Soccio 73). â€Å"Nous† is not an element, principle or process. It is defined as the Mind which sets the pattern of the universe. This â€Å"Nous† influences the things of the world without being contained in them (Soccio 73). The pre-Socratic tradition is different from Socratic philosophy. It is through the differences between the two in which Socratic philosophy can be defined. The pre-Socratics were interested on cosmology—the causes behind the workings of the world (Soccio 63). They investigated on nature and the world. Meanwhile, Socratic philosophy is not limited to cosmology. Socrates himself did not write anything, and his teachings were only reflected through the works of other thinkers (King 23). One of those thinkers, and the most influential Socratic philosopher, was Plato. Socratic philosophy is interested in a wide range of philosophical disciplines, which include epistemology, ethics and metaphysics (King 24). The metaphysical influence of Socrates is evident in Plato’s theory of Forms (Kraut). Another difference between the pre-Socratic tradition and Socratic philosophy is approach. Pre-Socratic thinkers did not have a specific approach to philosophy. Initially, they were more concerned with subject matter rather than method (Soccio 63). On the contrary, Socrates is recognized for his approach or method. It was Socrates who started the process of cross-examination or elenchus; this is popularly known as the Socratic Method (King 23). This process does not impart knowledge; it includes a system of questions which soon reveal what a person really knows. Plato followed this method, as most of his works were dialogues which feature Socrates (King 24). Just like Socrates, Plato believes that knowledge is not acquired, but simply recollected (King 24). The pre-Socratic thinkers and the Socratics also share similarities. For instance, how do these people count as philosophers? The answer is the same for both. They are philosophers because they were dedicated to seek the answers for questions about nature, the world or life in general. A philosopher is not distinguished for his wisdom; rather, he is defined by his love for it (Soccio 63). A philosopher is a thinker who seeks out the truth; he devotes his energy in investigations and observations which would bring him closer to the truth. Pre-Socratic thinkers, Socrates and the other Socratics are similar in this account, as they all love wisdom and inquire about the truth. Another similarity between the pre-Socratic thinkers and the Socratics is rational discourse. All these thinkers support their arguments with reason. Rational discourse necessitates the use of reason in establishing views on reality so that it could be properly verified (Soccio 65). It is a fact that Socrates had a monumental influence on philosophy. However, that does not mean that pre-Socratics have a lesser role in the development of philosophy. The role of Socrates in the history of philosophy is just as important as the thinkers that came before him. Between the pre-Socratic tradition and the Socratic approach, there are more differences than similarities. Regardless, both of these have made remarkable contributions to philosophy in general.

Use of Minnesota Multiphasic Personality Inventory to Evaluate Post Tra

Post-Traumatic Stress Disorder (PTSD) frequently headlines newspapers and newscasts across America. Veterans fighting in Iraq and Afghanistan return to a life they left but inside they are tormented with flashbacks, nightmares, anxiety, anger, and depression. Many people suffer from PTSD after experiencing traumatic events in his or her life. Minnesota Multiphasic Personality Inventory (MMPI-2) is chosen for the basis of this assignment to evaluate someone who exhibits symptoms of PTSD. Sometimes the symptoms of PTSD are exaggerated or faked. The basic characteristics and the purpose of this tool will be discussed as well as how the tool is used. An analysis of the MMPI-2 will reveal the relationship between MMPI-2 and a major theory of personality. After identifying the psychometric properties for PTSD populations, the question of the adequacy of MMPI-2 will be answered by reviewing literature. Last ethical considerations will be analyzed. Selection of instrument, characteristics, uses and purposes PTSD is a type of anxiety disorder resulting from experiencing a traumatic event in life. The person will relive or re-experience the event through flashbacks, nightmares and fear-evoking memories. Some report being hyperaware or constantly aroused, expecting the event to happen again. Soldiers comment on falling to the ground at a loud bang, constantly surveying the area around them, having an exaggerated startle response. Many do not talk about his or her experience; have sleep problems, anger issues, and trouble concentrating. Abuse of alcohol and drugs is common to try to deal with the anguish inside (PTSD Support Services, 2010). The MMPI-2 consists of 567 true and false questions taking 60 to 90 minutes to complete.

Technology in Transportation Essay -- Computers Machines Papers

Technology in Transportation Throughout history, getting things (and people) where they need to go has been a pretty basic need. The Romans needed to move stone to build their aqueducts; the nobles wanted luxury spices and silks brought to them from far off lands; ancient cities needed to move vegetables and grains from the farms, to storage, and then to the cities to feed the populace. Transportation has always been one of the backbones of every great civilization, without the ability to move goods long distances, your 'culture' was only the distance you could go conveniently to get what was necessary for survival that you could not produce. The industry boomed during the railroading system and hasn't slowed since. First, there were ships and horse-drawn carriages, then cars, now huge 40 ton trucks and jumbo air-liners. In today's changing business environment, information technology plays an incredibly important role in almost every aspect of the day to day life of almost every industry. The transportation industry is, of course, no different. From the transport of goods from manufacture, to warehousing, to retail, to end-user, the industry relies on information technology to get things done. The transportation of people is the exact same; incredibly important to get done yet impossible without the impact of information technology. Technology in Moving People The transportation industry (airline, railway, bus transit, automobile rental agencies) has undergone enormous changes in the way its customers purchase tickets and place reservations. The continuing popularity in e-commerce combined with the widespread increase in the number of people with internet access has caused an explosion in the number of... ...t an amazing 10% per quarter. An example trend that is quickly developing in the freight cargo industry is the leasing of freight aircrafts to different airlines. The aircraft, crew, insurance and maintenance is included in the leasing. Works Cited http://www.aaafoundation.org. revised 15 March 2004.

My Worst Nightmare

As the rain hit me like a thousand knifes, I checked my disreputable, scruffy watch for the time. I had a few more minutes until I had to be at the diminutive, quiet corner shop across from the busy train station to meet Emmy before school. The rain was starting to come down heavier so I took out my incomplete tartan umbrella and covered my reddish-brown hair. Black clouds filled the sky like poisonous fumes in the clear blue sky. I could barely see the deserted phone box ahead of me because of the intense muggy fog. I started to feel worried and nervous as I hated Emmy shouting at me every time I was late. I heard a car pull up by the side of the abandoned street a few metres ahead of me. From what I could see, the old car was blue and inside it were two men. As I innocently hurried past the tatty vehicle one of the men bellowed†¦ â€Å"Scuze me, got the time darlin'?† â€Å"Sorry, I'm in a rush, can't stop.† I replied â€Å"Jump in, I'll drive you. Where you off to?† I thought about it for a few seconds then took up the offer. â€Å"Well just around the corner then, cheers.† â€Å"Hop in then, what ya waiting for?† I didn't feel scared, although I knew it was wrong. I was fine; I just concentrated on getting to the shops in time. Time passed slowly and the traffic was diabolical. â€Å"Look guys, thanks a lot but if you don't mind I'll get out here and walk, the traffics gonna take forever† â€Å"No, we'll get you there don't worry.† I unlatched my rough seat belt and attempted to open the chipped, jammed door but it just wouldn't budge. I started to panic; the two men who seemed to be nice gentlemen had now turned into my worst nightmare. Sweat poured down my delicate face like a swiftly dripping tap. â€Å"You're staying put young lady, until I say so† said the driver sternly. I was terrified, where were they taking me? I slowly pulled out my red, run down phone and started to dial in ‘999'. I trembled with fear as I keyed in the three simple digits. â€Å"What you got there hey?† I quickly slid the phone behind my stiff back as I hesitated to answer the fully-grown, evil looking man. â€Å"Nothing, I swear, nothing† † You liar, give that to me you little brat!† I started to cry, I felt scared, I wish I'd taken the sensible way out and walked to meet Emmy. We passed the bakery; I could smell the succulent sweet, freshly cooked bread, which reminded me of home. Tears ran down my cheeks like the rain on the car window They pulled up outside a desolate warehouse, fear ripped through me like a cat tearing at a cushion. I looked around to see if I recognized where I was but I could just about focus on the horse riding stables and I knew that I was close to a local bus station. They dragged me into the warehouse like a sack of rotten potatoes. The warehouse smelt of vermin and vomit. It was dark and bloodcurdling. The walls were painted dark, repulsive green and they were covered in dirt and stains. There were only two chairs in the tiny warehouse, except for a few empty cans of beer lying around the floor. Rats scattered the cold floor for the slightest bit of food. The air was misty and smelt of damp clothes. The men tied me up to a loose, rusty radiator and started to search my pockets, they pulled out a florescent green lighter. The small man laughed in my face and dashed the lighter across the floor. I felt my heart skip a beat. The tallest man slapped me across the face, I screamed with pain and trepidation. â€Å"AAAhhhhhhhhh!† I began to aggressively cry again, the small hideous man kicked me and slammed an empty Fosters can in my eye. It hurt like hell. How long would I be here? Thos questions ran back and forth through my head like a swing. As the men headed towards the door, the tall obese man called out â€Å"there's no way of escaping!† They both sneered with joy together as they left me alone in the empty warehouse. I lent back against the freezing, brittle radiator. Tears streamed down my face. ‘How could I be so stupid?' I thought of my mum, I wanted to be with her, for her to cuddle me like I was a little kid again. â€Å"Help, can anybody here me?† I gave up, nobody could here me, and so I sat there and waited, and waited. I suddenly heard a knocking at the door. â€Å"Hello?† I was desperate to here a reply. â€Å"Help me please, I can't get up, I'm tied up† Surprising there was a voice, a friendly voice. â€Å"Just give me a minute, I'm doing all I can to get in† My heart was beating faster than the speed of light. This could be my chance to get out, to escape and be free of these daunting men. The person on the other side of the door was shaking the door and from what I could here it sounded like they were hitting the door with an axe. After 20 minutes the door finally gave way, and when it opened, standing in the doorway was a tall figure. He ran over and started to untie the ropes around my arms and legs. I stood up and stared at the man, he looked so kind and gentle. I gave him the biggest hug and insisted we got out of there as quickly as possible. The man, Mathew, drove me home. In the car it was silent, I was still in great shock and he didn't know what to say to make me feel better. When we got to my road, I thanked him and got out of the car. He watched me walk to my door to make sure I got there ok. I rang the bell, and after a few seconds my mum answered the door. It was such a relief to see her; I gave her a massive hug as tears streamed down my face. She looked at me in confusion as we went into the house. We both sat down on the leather sofa, as I began to tell her the story of my worst nightmare.

Free Essays on What Do You Say After You Say Hello

â€Å"What do you say after you say hello†, by Eric Berne,M.D. What do you say after you say hello? This question is asked all over the world by different people and the reason it can’t be answered is the basic psychological garbage we all have inside our heads. Our mothers, fathers, grandmothers, grandfathers, and anyone else who has a predetermine thought about how people should live their lives. Berne says that people have an illusion on how we react to each other. Such as if you meet a person and we talk to them as what we call â€Å"normal† voice and looking them straight in the eyes and then find out he/she is dying we get up set because we feel that we did not give them the respect that was need like in a low voice with our heads down and not looking them in the eyes. We forget that they are living now in the present and not in the past or in their heads. We have a predetermined attitude towards that person. Berne’s theory is that we have had to learn these notions about people from our family and the ancestral attitu des. Berne also writes about the different types of scripts that people have such as; the winners, losers, non winners, sex scripts, and the clock time and goal time. The most typical scripts that most people are; little pink riding hood or the waif, Sisyphus or they you go again, little miss miffit or you cant scare me, old soldiers never die or who needs me, the dragon slayer or daddy knows best, Sigmund or if you cant do it one way try another, Florence or see it through, and tragic. Dr Berne’s conclusion was that the harder the script that the person has is the easies to talk to a stranger.

Helicopter Investigation Essays

Helicopter Investigation Essays Helicopter Investigation Essay Helicopter Investigation Essay Aim: To investigate the factors that effect the time for a card helicopter to reach terminal velocity. Theory/Key Factors: When a helicopter wants to take off it starts its blades moving, and the blades push air under themselves until it they have enough air under them to take off. This is related to a sycamore seed, which is what I am basing my helicopters shape on. Terminal velocity is when air resistance is equal to the force of gravity acting on the helicopter. Therefore, the acceleration is zero and the helicopter falls at a constant speed. When my helicopter starts to spin it means that it has reached terminal velocity. The bigger the air resistance is on the helicopter is, the larger the surface area is, and consequently it will take longer to fall. The speed at which the helicopter falls at also depends on the conditions that I drop it in. To get round the problem of it being an unfair test if we dropped it outside, because of the wind speed, I have decided to drop the helicopter inside. The shape and size of the wings could affect the speed because some of the wing shapes might be more aerodynamic, in which case it would fall at a faster rate. In addition to this, the length of the handle of the helicopter might influence the rate at which it falls. Prediction I predict that the number of paperclips attached to the helicopter should not affect how great the terminal velocity is, or how long it takes to reach terminal velocity. This is because, as Galileos theory shows, objects of the same shape fall at the same rate in air, on earth (9.81 msec-2), regardless of mass, because there is no difference in the amount of air resistance. Hence, the helicopter should reach terminal velocity at the same time, regardless of its mass, as there is virtually no change in its shape. If it reaches terminal velocity at the same instance each time the experiment is conducted, then the terminal velocity will always be the same. This is because, if it is to follow the law V= u+at, the greater the product of at (acceleration and time) the greater the velocity (in this case terminal velocity). Since u is always 0 in our experiment, this does not influence the relationship between the time taken to reach terminal and terminal velocity, and the above reasoning st ill holds. However I predict that our experiment will support the law V= u + at, but will not support Galileos theory due to human error in measuring the accurate time of when the helicopter starts to spin and when it hits the floor. Diagram Method 1. By using my T-Shaped helicopter that I picked from my preliminary experiment, I will add one paperclip to it and then drop it from a height of five metres. * I will record the time from when I drop it until it hits the floor, in addition to this I will note down the time when it starts spinning (terminal velocity). 2. I will repeat the test three times with one paperclip, then I will put two paperclips on and do the test three times, and finally I will place three paperclips on and repeat the test three times. I do this because it means that I get more accurate results. Safe/Fair Testing To make it a fair test I will: * Use the same helicopter each time so that the wingspan and weight are the same throughout. * Drop the helicopter from the same height (five metres). * Drop the helicopter from the inside so that there is no interference from the wind. * Try to make sure that the paperclips are about the same size and that they are roughly the same weight. To make it a safe experiment I will take the following precautions: * I will look before I drop the helicopter, so that it doesnt hit anybody. * I will be careful when using the scissors to cut out my helicopter. * I will follow the laboratory rules to avoid any accidents. Preliminary Experiment By doing this experiment I hope to find which helicopter I could use in my main investigation, by investigating wingspan. Secondly, I hope to find a suitable range of paperclips with in which to conduct my experiment. I will use the same T-shaped helicopter in this experiment, as I will in the actual test, to make my experiment fair. I will drop my helicopter from a height of five metres (same in actual experiment) and repeat it three times so that I get more accurate results. Results: Wing surface area (cm2) Average time to reach terminal velocity (S) 1 paperclip 4 paperclips 7 paperclips 10 0.83 1.09 1.42 20 0.64 0.74 1.29 30 0.49 0.67 1.21 40 0.57 0.72 1.18 50 0.56 0.79 1.26 Preliminary Conclusion From my preliminary experiment I can see that overall the best helicopter wingspan for my experiment is thirty cm2 and the best range of paperclips to have on the helicopter is between one paperclip and four paperclips. I chose these two factors because when using one or four paperclips the helicopter reached terminal velocity the quickest, the and when I used a wingspan of thirty cm2 it reached terminal velocity fastest. Results Number of paperclips Time when dropped (s) Time when helicopter reached terminal velocity (s) Average time when started to spin (s) Time when it hit the floor (s) Average time when it hit the floor (s) Terminal velocity (m/sec, 1 D.P) Average terminal velocity (m/sec, 1 D.P) 1 0 0.53 0.48 2.57 2.49 5.2 4.73 0 0.48 2.48 4.7 0 0.44 2.41 4.3 2 0 0.54 0.56 2.51 2.57 3.3 5.57 0 0.56 2.59 5.5 0 0.59 2.60 5.9 3 0 0.64 0.61 2.81 2.92 6.3 6.0 0 0.55 3.01 5.4 0 0.63 2.94 6.2 * The equation that I used when calculating the terminal velocity of the helicopter (the velocity when it began to spin) was V= u+at. In this experiment: * V was the final velocity, * u was the initial velocity, 0 * a was the acceleration, which was 9.81 msec-2 (2.d.p.), the acceleration of all things under the gravitational pull of earth in air at room temperature. * t was the time taken for the helicopter to begin spinning once it was dropped. Analysis The results of our experiment show that the helicopter reached terminal velocity (on average) earliest when it had 1 paperclip attached to it (0.48 seconds), and it reached terminal velocity latest (on average) when it had 3 paperclips attached to it (0.61 seconds). This is shown in the bar graph between the number of paperclips and the average time taken to reach terminal velocity. The scatter graph between the terminal velocity and the time taken to reach it shows that the greater the time taken to reach terminal velocity, the greater the terminal velocity. This follows the law V= u+at, as the greater the product of at (acceleration and time) the greater the velocity (in this case the terminal velocity). Since u is always 0 in our experiment, this does not influence the relationship between the time taken to reach terminal and terminal velocity. The scatter graph also shows that the larger the weight of the helicopter, the later it reaches terminal velocity and hence the greater the terminal velocity. However, this does not comply with Galileos theory, which follows what I predicted. This is possibly due to human error, although this is not definite, which means that it cannot be ascertained whether this totally supports my prediction. Evaluation The evidence found cant be trusted fully for its scientific merit as there is a large possibility that a substantial amount of human error was involved. The method itself has a lot of faults due to human error. These include, the delay when starting the stopwatch for when the helicopter starts to fall, when it starts spinning and when for when it finally reaches the floor. In addition to this, the height and angle from which the helicopter was dropped from was not constant throughout the investigation, due to the fact that when I was dropping it I had my arm at different angles and at slightly different heights. As you can see from my graph, the experiment I did with two paperclips was the most accurate because the error bars are very close together. The experiment I did with three paperclips was the least precise because the error bars are spread out more. Due to Galileos theory I cant single out the anomalies because Galileo says that there should be only one correct answer, however I cant tell which one it is. To stop this from happening again, I could make my results more accurate by using a stopwatch that went to more decimal places. I could also test a wider range of paperclips so that I would be testing from no paperclips at all, until I reached an amount of paperclips where the helicopter didnt have time to start spinning.

Compare Online Relationships with Face-to-Face Relationships Essays

Compare Online Relationships with Face-to-Face Relationships Essays Compare Online Relationships with Face-to-Face Relationships Essay Compare Online Relationships with Face-to-Face Relationships Essay Perhaps, to think that online relationships are in some points more superficial, deceitful or perilous than face-to-face relationship is such a dangerously-shallow deception. In fact, online relationships aren’t much different from real life relationships. Despite the fact that people have grown panic towards online relationships lately, face-to-face relationships themselves don’t serve any fewer disadvantages. Somehow it has been believe to be true that online relationships and face-to-face relationships are totally unalike, nonetheless the two elationships share three similarities covering intimacy, sincerity and risks. The first similarity concerns level of intimacy between two people in the relationship. Face-to-face relationships allow people to actually meet in person. In a real-life situation, they can see each other or have conversations with real interaction, such as eyes contact and body languages. The relationships can develop into fur ther closeness and sometimes the couples end up with marriage. Similarly, all types of interactions provided in face-to-face relationships also exists in online relationships. By using interactive devices, such as web cameras, microphones and speakers, actual talking and seeing becomes possible through the internet. Deeper intimacies like serious relationships or marriage are also feasible for many internet couples. A new study of online dating site members has found that when couples who had built up a significant relationship by e-mailing or chatting online met for the first time, 94 per cent went on to see each other again. Moreover, the study also shows the successful relationships which last at least seven months and in some case over a year. This result proves that online relationships have a similar degree of success as real life ones. (Dr Gavin and Dr Adrian Scott, 2005) Additionally, according to the online dating research conducted by Marry Madden and Amanda Lenhart in 2006, nearly 3 million adults have entered long-term relationships or married their online dating partners. These evidences confirm that the situation of online dating is not any less real than face-to-face relationships. Secondly, the two relationships have something in common dealing with sincerity. In face-to-face relationships there are opportunities to meet not only decent people but also the spurious. People lie, research has shown, in one-fourth of their daily social face-to-face interactions especially when it comes to the relationship issues. (Cornell University communications researchers, n. d. ) For example, some lie about having an affair. One study found that 2/3 of the wives (26 to 36 million women) whose husbands were cheating had no idea their husbands were having an affair. This’s because their husbands lied to them and they failed to recognize the telltale signs. Moreover, 25 percent of men and 17 percent of women had been unfaithful no matter how many years there’ve been married. (National Opinion Research Center, n. d. ) Likewise, online relationships offer both sincerity and deception. Nowadays, it has been on the news that internet relationships mostly lack elements of truth and frankness. Anyone can make up his or her profile about the looks, personality, occupation, education, financial status, or even name. These disadvantages of online relationships can occur in face-to-face relationships as well. However, honesty is not mpossible to find in cyberspace, due to the fact that there still be lots of genuine people using internet as a tool to find the right person for them to have relationships with. Furthermore, sincerity can also be found in other forms, several kind of support groups, such as groups for anxiety, depression, and substance abuse. As some of the members of each group share their own experiences, their relationships become a sincere binding between them and develop to further possibilities. All these proofs proves that online relationships should not be accused of eing more doubtful in term of sincerity than face-to-face ones. The last but not least similarity has to do with the risk. Both online relationships and face-to-face ones have the possibility to be deceived for money, sexual intercourse, physical assault or even homicide. Crime rates in online relationships as well as in face-to-face ones have been increasing. In real life, by 1991 the dramatic crime rate was 313% the 1960 crime rate and the rates are continuously increasing. Approximately 5% of the U. S. population, thirteen million people, are victims of crimes every year. United States Crime Rates, 1960 – 2006) The categories of crimes cover property thefts such as robbery and forgery as well as violence ,such as murder, forcible rape, physical and mental assault. Similarly, online relationships can lead into any categories of crimes that occur in face-to-face relationships. The cyber crime rates are also rising 255% in 2006 over 2005. (US. National Crime Records Bureau statistics, 2005-2006) According to the statistics, no obviously different risks between face-to-face relationship and online relationships appear. Summarily, people trend to e panic so much on online crimes that they overlook the fact that crimes that are caused by people in real life don’t have any less rates than online ones. It’s more than clear that, in contrast to what has been believed, both online relationships and face-to-face relationships carry the similar qualities in term of closeness, frankness and peril. In other words, internet relationships are no worse than the real life ones. Perhaps it’s time to reconsider our attitude towards this cyber romances as a virtual alternative relationships and to open the doors of opportunities and understanding for those millions online daters.

Money cannot buy happiness Essay Example | Topics and Well Written Essays - 500 words

Money cannot buy happiness - Essay Example But, this is paradoxical as money can’t really buy happiness. It is written in many spiritual texts that money can only buy the source but not true content of happiness. For example, money can buy a house but not a home filled with love and affection; it can buy a bed but not sleep; it can buy companions but not friends. Money is required for satisfaction of material wants, and there is no end to human wants. In the race of achieving more and more material needs, man tends to forget to be happy. Man is a social animal and cannot live in isolation. Rich men attract people, but hardly have any friends; or, tend to lose friends in due course because their focus is towards making more money rather than to give time to their beloved ones and value their affection (Jet, 15). As a result, men having money become lonely with no people to care for by the end. Such life is certainly not a happy one. Happiness lies in being cared for and caring for others. Money cannot prevent one from losing his/her life; only love and affection can be cherished even after the loss. Jet Magazine quotes that the psychologist, Dr. Lewis-Jack believes that real happiness is ‘peace of mind, good health and being content with yourself and where you are at this point in your life; having goals and a willingness to work toward achieving those goals’ (p.18). This is very true because chasing after money will affect one’s health in the due course of time, which will necessitate treatment and care. For this, the person will have to rush to health care where he will receive care upon paying money; but, this care will not be original and true to his/her internal satisfaction. Secondly, chasing after money causes mental and emotional stress; this will manifest in the form of quarrels, misunderstandings, depression, anxiety and fear. Greed for money will also

Data Analysis - Essay Example ysing the factors which influenced mind during voting, particularly how their educational qualifications, religious leanings, gender income, etc., influenced their voting behaviour. Various political and social developments impacted the voting behaviour of the people in the British elections. As stated by Alvarez and Nagler (1997), in the United Kingdom, â€Å"the sustained revival of the Liberal Party since 1970, the rise of nationalist parties in Wales and Scotland, and the new Social Democratic Party, poised significant challenges to the established two-party system.† Apart from these aspects, studies were conducted to find out certain personal and social factors also impacted the voting behaviour. One of the key aspects which is thought to influence the voting pattern of the voters is their education and thereby intelligence levels. Deary, Batty and Gale (2008) in the 1970 British Cohort Study, examined the relation between childhood intelligence and how those people voted at the ages of 30 and above during the 2001 UK general election. The studies found that, â€Å"People with higher childhood intelligence were more likely to vote in the 2001 election (38% increased prevalence per SD increase in intelligence), People with higher childhood intelligence were more likely to take part in rallies and demonstrations, and to sign petitions, and expressed a greater interest in politics (40%, 65%, 33%, and 58% increased prevalence per SD increase in intelligence, respectively).† (Deary, Batty and Gale 2008). The other aspect, which could also inf luence the voters during the voting process, is their religious leanings. Kotler-Berkowitz (2001) points out how data from the 1991 and 1992 waves of the British Household Panel Study, when statistically analyzed (using multinomial logistic regression analysis) state that religions influence the voting decisions of sizable number of British citizens. â€Å"Religious belonging, behaviour and belief, as well as the religious context

Summarising a Scientific Journal Literature review

Summarising a Scientific Journal - Literature review Example Theoretically, this complexity and variability in conclusions implies that parameters used in achieving mixing quality will not always be independent but inversely related to each other (Wolfgang et al., 1999). Practically, all laboratory experimenter are admonished to be very watchful in guiding the fluid mixers in order to achieve uniform outflow of micro channels. Major Findings: Results are in three sections though they all centre round mixing quality. On mixing quality and loss pressure, results revealed that in the presence of large range of volume flow, there is tendency of quality mixing can be achieved if the conditions of proper combination of slit and micro channels are adhered to. This implies that experimenters must be proactive in their choice of micro channel selection. Similarly, Hessel et al. (2005) point out that â€Å"quality mixing can be accomplished by time-pulsing flow owing to a periodical change of pumping.† On the parallelization of mixing elements, r esults showed that reactants achieve high volume flow when channel depths are increased in a single mixing unit. This implies that when using one single mixing unit, parallelization of mixing which ensures increased volume flow in specified regions of >700mL/h cannot be realized. On the actual volume flow as it relates to quality mixing, the results showed that there could be deviations on the volume flow depending on the mixer array. This assertion is however disagreed by Omega (1995) who posits that in a fully laminar system, there is supposed to be constant mixing quality whenever mixing is done over an entire flow range. Weaknesses and Strengths: In the methodology, what was supposed to be an experimentation ended up using too many secondary data and comparative assumptions. For instance instead of the researchers monitoring the mixing time, they stated, â€Å"the mixing time cannot be directly measured by the test reaction. Instead a comparison was made for mixing elements hav ing various channel widths.† It will be noted that any element of mixing is highly important in the results achieved in any micro-mixers experiment. However, the researchers choose comparative assumption. On the use of secondary data, it is admitted that secondary data helps in making qualitative analysis of data highly valid; however in the actual collection of data, it is important that there is a distinction drawn between primary data collection and secondary data collection. If for nothing at all, the researchers could have different sections of their project report, depicting these two variations. The research report has a number of strengths. For instance the presentation of data was very vivid amidst the use of diagrams and figures to elaborate all points. Again, the entire report was well segmented, making the use of the document very easy to follow. For instance the researchers used sub-topics to differentiate new ideas. Suggestions The beauty of all research work is that they are a continuous process. This means that there is always room for improvement and advancement. To this end, some few suggestions are made towards the future improvement of the research work. It is suggested that future researches should make clearer distinction on active and passive mixing principles. This suggestion is given against the backdrop that whenever active and passive principles are used, researchers always have the chance of considering expanded scopes of

The company will focus on making of quality beads and jewelry which are cheap for locals to buy and attractive to tourists. In order to achieve this, the company will need to purchase various local materials and beads, which will be combined in different colors and proportions to appeal to the customers. The company will be dealing in making of jewelry and beads, which will be used as ornaments, beauty products in the house, decorations in public occasions like weddings and general decorations in offices. The company will need beads shaping machines, firing equipment and a number of workers who will be joining the beads and jewelry to form meaningful shapes and structures. Paints and colors will also be needed to turn the sculptured beads into the desired colors and decorations (Dismore, 15). Market identification is a crucial thing for any business. It is the realization of the different needs of different markets and structuring products so that they can suit every buyer in the market. This phase of business formation is crucial because without good market identification the business will incur loses and eventually fails in operation. The best segmentation technique in the jewelry line of business is the using demographic factors. In this case, an entrepreneur is supposed to consider such factors as age ranges and their concentrations in the market, gender ratios, and its effect in the market, the different ethnic communities in the market, and education levels of the community. Other factors that also need to be considered include the different occupations in the community, the religion and religious views of the community and the income status of the different families in the community (Dismore, 33).

History and development of international law Essay

History and development of international law - Essay Example Despite existence of the political, global and territorial differences the whole world is considered as a global village and such concept mainly enhances the idea of universal brotherhood. At the same time in the context of trade, cultural intercourse, the idea of globalization plays a major part. In this context it needs mentioning that no matter how much the globalization aspect seems positive and flawless but at the same time it includes several lacunas. In this global society also the superior nations are finding an opportunity to show their aggression, to inflict oppressive approaches towards the other nations, their people and their economy. The rate of crime has also increased to a great extent and most of the criminal, after committing the criminal deeds flee to other nations to seek shelter. As administrative system of a particular nation does not have the power to exercise the hold over other jurisdictions, the fear of being caught is reduced to a great extent for those cri minals. At the same time economic aggression is also taking a brutal shape. According to modern international treaties in the post World War II situation it has not been possible for the nations to exaggerate the power of politics to express their imperialistic mentality. Thus, those nations have adopted the procedure of economic aggression through which a superior nation can enjoy economic hold over the other nation through trade relationship. Thus, the importance has also been realized by legal scholars that there must be some kind of restraints that prevent one nation to become havoc over the other. These are some of the typical situation; rather problems at the international level that generated the emergence of this new discipline of legal jurisdiction: International Law. Legal and scholars of jurisprudence have attempted to provide definition of the International Law in different

Rock and Roll Assignment Example | Topics and Well Written Essays - 1000 words

Rock and Roll - Assignment Example The cultural phenomenon associated with the song is undeniable, but a close analysis of the music content exposes negligible evidence of explicit or revolutionary intents. The thrusting, shaking, and gyrating dance moves by Presley when performing this song were seen as fostering destructive and negative reactions to youths. The song has a twelve-bar blues, carefully structured to enhance dancing, particularly with the quick tempo. The song has a constant backbone thanks to the double bass present in the guitar solo and the chorus section. The drumming is just perfect. It is unadorned and simple; purposely and concisely striking on the song beats prior to blasting into machine-gun burst at every verse-end, revealing to the listener the beginning of a subsequent twelve bars. The lead guitar solo also encourages the listeners to dance due to its simple and rhythmic nature, and with the added advantage of not distracting the beat. The rhythm from the guitar is superb, as it provides a driving, compelling impetus. Moreover, the guitar rhythm plays at nine bars of the twelve bar pattern (Bennett 15). Simultaneously, strutting riff plays, adding the body and depth of the magnificent twelve bar pattern, and when its play stops, its absence reflects a certain conspicuous. Combine the rock and roll magic of these instruments with Presley’s voice, the driving force, perfect control, and power, and you get the most unique and popular song in the 1950s. 2. Art Garfunkel and Paul Simon Consumerist ideals dominated the 1960’s society, with Americans in upper and middle class struggling to attain a â€Å"model life†. The consumerist goals created a false sense of peace and security. The song â€Å"sound of silence† by Art Garfunkel and Paul Simon uses diction, clear metaphors, contrasting tones, and repetition to highlight the need for social changes. The 1960s had an awkward epoch where majority of the Americans dared not to question or criticize societal expectations (Perone 45). The song reflects the mixed emotions in the 1960s such as hopes of societal activists and submissive conformists for social change. Composed in the aftermath of President John F. Kennedy and the Vietnam War, the two artists reinforce the need for social change; condemn submissiveness, and ig norance using the term â€Å"silence†. The song uses various similes and metaphors to pass across the message. It highlights the American national well-being as a facade that most citizens are afraid to address. The lyrics to the song compares â€Å"cancer† to the disturbing the silence, highlighting the impossibility of changes in society at the time. Through such similes, Garfunkel and Simon highlight the complacency, stubbornness of upper and middle-class levels, especially with reference to nuclear family. The song may fall into the folk music category due to its style of writing. The song resembles storytelling, though it fuses with the popular genre of music during the 1960s, which was traditional folk music, thus the presence of electric bass, drums, and electric guitar (Perone 47). The use of rhythmic syncopations and those other instruments promote the essence of storytelling. This, combined with the audacity to question societal expectations at a time when it was considered a social crime, makes the song a great piece of rock and roll music. 3. John Lennon There was imminent danger of a possible lack of unity and peace in the world in the 1970s era. The revolutions that were taking place were a threat to world peace, and this perhaps triggered John Lennon of the Beatles to compose the song â€Å"Imagine†. The song is a strong, emotional, and though-provoking piece of music advocating for the

Study On The Alternative Medicine Reflexology

Study On The Alternative Medicine Reflexology Presently there are various methods of treatment for different types of diseases, such as cancer, asthma, and multiple sclerosis, and alternative medicine is becoming more prevalent among people despite the advanced technology. Many people nowadays try to avoid the use of medications because of the side effects. this is why people are attracted to alternative therapy techniques, because they want an effective treatment that is not costly and does not cause any harm. There are over a hundred different types of alternative medicine and the number is still growing. A few examples are: chiropractic, reflexology, hypnotherapy, reiki, ayurveda, kinesiology, homoeopathy, osteopathy, cranial therapy, various types of acupuncture, colour-therapy, massage, and sound therapy [1]. For example, Reflexology has been widely used in fields such as midwifery, orthopedics, neuroscience and palliative care [2]. 1.1 What is Reflexology : Reflexology is the physical act of applying pressure to the feet and hand with specific thumb, finger and hand techniques without the use of oil or lotion [3]. It is also called zone therapy, based on the notion that each body part is represented on the hands and feet and that pressing on specific areas on the hands or feet can have therapeutic effects on other parts of the body. The body is divided into 10 longitudinal zones-five on each side of the body. Each organ or part of the body is represented on the hands and feet; massaging or pressing each area can stimulate the flow of energy, blood, nutrients, and nerve impulses to the corresponding body zone and thereby relieve ailments in that zone[4]. Each part of the foot represent a reflex area that correspond to specific organ or part of the body, for example: the tips of the toes reflect the head the heart and chest are around the ball of the foot the liver, pancreas and kidney are in the arch of the foot low back and intestines are towards the heel This concept was furthered by physiotherapist Eunice Ingham into the modern practice of reflexology. Dr. William H. Fitzgerald, an ear, nose, and throat doctor, introduced this concept of zone therapy in 1915. American physiotherapist Eunice Ingram further developed this zone theory in the 1930s into what is now knows as reflexology. A scientific explanation is that the pressure may send signals that balance the nervous system or release chemicals such as endorphins that reduce pain and stress [11]. 1.2 The difference between Reflexology and Foot Massage: Reflexology is different from foot massage in that it involves more superficial contact, deeper pressure on certain parts of the foot and resembles a caterpillar-like movement. It has been claimed that by pressing the reflex zones, energy blocks or disturbances such as calcium, lactate or uric acid crystals are reabsorbed and later eliminated a process referred to as detoxification'[2]. In foot massage people typically use massage oil or lotion and use gentle gliding strokes all over the foot. Reflexology is quite different, while many people find reflexology relaxing. One of the reasons people often confuse the two is that some spas and salons advertise that they offer reflexology, but what people actually get is foot massage by a therapist who isnt properly trained or certified in reflexology [12 ]. 1.3 Reflexology Foot Chart: 1.

MIGRAINE can be relived by applying pressure on these areas: Head(1), frontal and temporal areas(4). BACKACH can be relieved by applying pressure on specific areas; Hip and lower back(38), spine(15). Immune system: TUMOR (CANCER) can relieved its symptoms by applying pressure on specific areas; Spleen (20), lymph areas (6), tonsil (52) (also reflex areas relating to the cancerous regions). Respiratory system: ASTHMA can be treated by applying continuous pressure on these areas: parathyroid(7), lungs and bronchi(12), kidneys(25), ureters(28), bladder(34), lymph areas(6). Also BRONCHITIS can be treated by applying pressure on certain areas such as parathyroid(7), lungs and bronchi(12), adrenal glands(23), lymph areas(6).

INFLAMMATION OF THE HIP JOINT can be treated by applying pressure on certain areas such as stomach duodenum(18), kidneys(25), ureters(28), bladder(34), hip(38), waist(27), vertebra and spine(15). And Parkinsons Disease can be treated by applying pressure on certain areas such as Head(1), neck(5), parathyroid(7), adrenal glands(23), stomach duodenum(18), pancreas(16), liver(19), small intestines(32), colon areas(26,29,30), kidneys(25), ureters(28), bladder(34), rectum(41) [14]. 1.5 History of Reflexology: Around the world and throughout history reflexology has been rediscovered and reinstated as a health practice time and time again by peoples around the globe seeking to deal with health concerns. Archeological evidence in Egypt (2330 BCE), China (2704 BCE) and Japan (690 CE) points to ancient reflexology medical systems. In the West the concept of reflexology began to emerge in the 19th century, based on research into the nervous system and reflex. While no direct evidence of direct cross-fertilization from ancient times has been discovered, the practice of foot and hand work in a variety of cultures, belief systems and historical periods speaks to reflexology for health as a universal bridging concept [3]. Reflexology was introduced into the United States in 1913 by William H. Fitzgerald, M.D. (1872-1942), an ear, nose, and throat specialist who called it zone therapy. He used vertical lines to divide the body into 10 zones. Eunice D. Ingham (1899-1974) further developed reflexology in the 1930s and 1940s, concentrating on the feet of Mildred Carter and a former student of Ingham subsequently promoted foot reflexology as a miraculous health method. A 1993 mailing from her publisher stated: Not only does new Body Reflexology let you cure the worst illnesses safely and permanently, it can even work to reverse the aging process, Carter says. Say goodbye to age lines, dry skin, brown spots, blemishes with Body Reflexology you can actually give yourself an at-home facelift with no discomfort or disfiguring surgery[4]. Some reflexologists who deny that they diagnose or treat disease claim that the majority of health problems are stress-related and that they can help people by relieving the stress associated with various diseases or body organs. And this type of double-talk is similar to chiropractic claims that subluxations lower resistance to disease and that adjusting the spine to correct subluxations will improve health [4]. 1.6 The benefits of reflexology: Our bodies are endowed with a wonderful self-healing potential. Sadly, this potential often remains unfulfilled because the vital energy pathways are blocked by illness, stress, congestion, injury, and toxicity. By applying a constant and alternating finger and thumb pressure to the feet and hands, the reflexologist induces a prolonged state of deep relaxation. Through relaxation, the body returns to a state of balance (known as homeostasis), as the energy flows freely from fingers and toes to the head, and only then can the body heal it [5]. It has also been suggested that reflexology may help release stress and tension, improve blood flow of the body and promote homeostasis. Anecdotal evidence has shown that reflexology is beneficial in many conditions such as pre- and postnatal discomfort, pain, migraine and chronic obstructive pulmonary disease. Other therapeutic effects, such as strengthening the immune system, improving sleep quality and wound healing, have also been claimed [2]. Reflexology like other forms of body work, can have a variety of benefits including [6]: Structural benefits: assistance with physical problems such as pain and mobility Emotional benefits: help in providing nurturing and holding Energetic benefits: restoring and mobilizing energy for self-healing The benefits of reflexology in general include [3]: Relaxation Pain reduction Amelioration of symptoms for health concerns Rejuvenation of tired feet Improvement in blood flow Impact on physiological measures (e. g. blood pressure and cholesterol; measurements by ECG, EEG, and fMRI) Beneficial for post-operative recovery and pain reduction Enhancement of medical care (e. g. cancer, phantom limb pain, and hemodialysis patients) Adjunct to mental health care (e. g. Depression, Anxiety, Post traumatic stress disorder) Complement to cancer care (pain, nausea, vomiting, anxiety) Easier birthing / delivery / post-partum recovery 1.7 The theories behind reflexology: The theory that reflexology definitely works with the central nervous system of the body is built on the studies done in the 1890s by Sir Charles Sherrington and Sir Henry Head, who showed that there is a neurological relationship between internal organs and the skin and the bodys nervous system can adjust to a stimulus. Therefore according to this theory, a pressure applied to the hands, feet or ears will send relaxing and calming messages to various parts of the body from peripheral nerves in the feet, hands and ears [7]. The Gate Theory and The Neuromatrix Theory also explain why reflexology produces relief from pain and stress. The theories suggest that the brain creates pain which is a subjective experience in response to cognitive or emotional factors; therefore ones moods and factors like stress and tension can affect our experiences of pain [7]. Thus reflexology therapy reduces pain by improving the mood and reducing stress. Another theory states that the human body has vital energy and there is congestion or choking of the energy flow which causes illness and disorders in the body [7]. Surgical interventions and medical therapies continue to evolve and offer hope to people with acute and chronic diseases. However, both patients and healthcare staff aware that technology and aggressive treatments are not the only answer to providing care and improving wellbeing. Stone (2001:55) suggests that both UK and US there has been a significant shift towards integrated health care and greater tolerance towards the inclusion of complementary therapies by governments and the medical fraternity. There is evidence to suggest that an increasing number of hospital trusts are employing therapists or allowing volunteer practitioners to provide therapies such as massage, aromatherapy and reflexology. There are also a growing number of research projects reporting on the use and benefits of reflexology and foot massage in hospital wards, managing pain, reducing anxiety, improving perceptions of care [6]. With the fast development of reflexology, now there is something called clinical reflexology, which is an advanced form of reflexology. It covers the application of reflexology within specific areas of clinical practice, including maternity care, and palliative care. Clinical reflexology is adapted to the clients needs using the most effective techniques to help with the clients problems and issues [15]. 1.8 There is an arguing about the use of touch therapies such as reflexology in the hospital, and Ashcroft (1994) has highlighted the stresses of hospitalization with acute illness [6]: The anxiety arising from being in an alien environment Being disturbed constantly for clinical observations and the administration of often uncomfortable medical investigations and treatments. Fear of dislodging intravenous and monitoring equipment Being unable to drink and eat normally Physical discomfort made worse by wounds, immobility, invasive catheters and sleep deprivation Intrusion from noise, light and smells Separation from friends and family 1.9 Where is Reflexology practiced nowadays, and for whom is used : Reflexology, although most commonly practiced in the community (Coxon 1998, Lett 2000) is now emerging as a choice for patients being cared for in mental health setting, maternity care and palliative care settings[6]. It has been suggested in the nursing literature that the introduction of reflexology and other complementary therapies in healthcare settings, could be an ideal non-pharmacological way of managing difficult symptoms, such as pain and nausea as well as reducing stress and limiting anxiety. Aside from the patient feeling the benefits, relatives too appear to gain satisfaction from the provision of reflexology [6]. Identifying when and for whom it is appropriate to offer reflexology present challenges. Currently, provision of reflexology in acute hospital settings is largely on an ad hoc basis, delivered by existing healthcare staff or as part of a pilot or research project (Dryden et al 1999) [6]. Volunteer reflexologists may visit wards and departments supervised by clinical staff, providing only short treatments without any remuneration to selected patients deemed suitable for treatment. Finding a mutually convenient time is important, avoiding mealtimes, ward rounds and at peak visiting in the early evening. Dryden et al (1999) found that the best time to offer treatment was early afternoon, when the ward had a rest period and there were few visitors [6]. 2. Many literature reviews about the studies that been conducted to see the effectiveness of reflexology technique on symptoms occurs in patients with chronic diseases such as cancer and osteoarthritis. A study done by Nancy L.N Stephenson et al. on the effects of Foot reflexology on anxiety and pain in cancer patients. It is a quasi-experimental, pre/post and crossover study. A sample of 23 inpatients from different medical/oncology units in hospitals of southeastern united states with breast or lung cancer were participants in this study. The majority of the sample were female, Caucasian and 65 years old or older who were receiving regularly scheduled opioids and adjuvant medications on the control and intervention day. The patients were divided into two groups randomly. Group A: receiving a foot reflexology to both feet for 30 minute total by a certified reflexologist in the first contacts and group B: receiving the same intervention in the second contact. The pain and anxiety were measured using two instruments; the VAS, the simpler one and the Short-Form McGill Pain Questionnaire (SF-MPQ) prior and post the intervention time. The VAS used to measure the anxiety, is a 10-cm lin e with verbal anchors at each end stating not anxious at all to the most anxious I have ever been(McGuire, 1988). Following the foot reflexology intervention, patients with breast and lung cancer experienced a significant reduction in anxiety. Also one of three pain measures showed that patients with breast cancer experienced a significant decrease in pain. An additional study is required to determine the effects of foot reflexology on pain as measured by the intensity sections of the SF-MPQ, the VAS and IPP. There were no significant decreases in pain between the two groups because the crossover design allowed the 23 patients to be their own control; some of them were taking medications to manage their pain. Limitation of this study were the small sample size and the crossover design [8]. When reflexology is provided in a palliative care setting it is essential that the patient is at the center of the treatment process because living and dying is ultimately a unique, intimate and personal journey. Reflexology can offer a means of relieving physical symptoms and of facilitating emotional and spiritual wellbeing, but requires the therapist to practice with awareness, sensitivity, intuition and adaptability. Reflexology cannot promise sustained improvements in physical health but can provide therapeutic touch and the space and attention to support patients in connecting their mind, body and spirit [2]. Reflexology can also be invaluable in helping carers to cope both before and after the death of their loved ones. It is vital that reflexologists acknowledge their contribution within the team of health professionals involved in caring for the person and the family and the need for practice to be based on contemporary evidence-based knowledge. Sensitivity and humility enable the practitioner in reflexology to provide holistic, individualized and appropriate care for people at perhaps the most difficult time of their lives [2]. Another study is done by Miss.Serawal Haera et al. about the effect of reflexology on joint pain in knee osteoarthritis patients on 21 May, 2003. A quasi-experimental research method was used, a sample of 30 knee osteoarthritis patients with pain were selected by purposive method at the orthopedic clinic, outpatient department of Phrae Hospital. Simple change-over design was used in this study to compare the difference of joint pain scores among patients before and after intervention. The subjects were randomly assigned to the experimental period first followed by the control period, and vice versa. In the experimental period patients received reflexology for 1 hour/day for 7 days, and in the control period patients didnt receive reflexology for 7 days. The instrument for data collection were demographic data and information about knee osteoarthritis, the assessment of joint pain in patients with knee osteoarthritis, and a daily record of joint pain, medication used and daily activi ties. The data were analyzed by using frequency, mean, standard deviation and ANOVA for simple change-over design. The results of this study showed that the joint pain score in the experimental period after receiving reflexology was statistically significantly lower than during the control period. What this study revealed is that reflexology can be use as a complementary therapy to relieve joint pain and decrease drug used for pain relief [9]. In the study by Siev-Ner et al. (2003) the reflexology group demonstrated statistically significant symptom relief in a study of patients with multiple sclerosis. Compared with no improvement in the massage group, scores for urinary symptoms, paresthesia and spasticity were statistically significantly improved, whereas muscle strength revealed only borderline improvement at the end of reflexology. The improvement in paresthesia remained statistically significant at the 3-month follow-up [2]. Statistically significant reductions in the severity of hot flushes and night sweats, measured by a visual analogue scale (VAS), were reported after 6 weekly sessions of reflexology, but no statistically significant difference was found between the groups receiving reflexology and non-specific foot massage for menopausal symptoms in the study conducted by Williamson et al. (2002). In terms of general well-being, both the reflexology and non-specific foot massage groups demonstrated an improvement in the Womens Health Questionnaire (WHQ) score. However, the difference between the two groups was not statistically significant. Similarly, although improvements in the two sub scores (anxiety and depression) of the WHQ were detected, there was no statistically significant difference between the reflexology and foot massage groups [2]. In the study by Brygge et al. (2001), the outcomes of lung function tests including peak expiratory flow (PEF) and the ratio between forced expiratory volume in 1s and forced vital capacity (FEV1/FVC) did not improve after reflexology in patients with bronchial asthma. In addition, the reflexology group was not superior to the sham foot massage group in lung function improvement [2]. No statistically significant changes in patients with irritable bowel syndrome were observed either within or between the reflexology and sham foot massage groups in the study by Tovey (2002). Abdominal pain, constipation/diarrhea, and bloating remained unchanged after the reflexology treatment [2]. Also about the edema of the feet in late pregnancy, women with oedema in late pregnancy perceived less swelling and tightness as compared with the pretest level in the reflexology treated group, according to Mollart (2003). However, there was no statistically significant improvement in mean ankle and foot circumference measurements after lymphatic reflexology. There were also no statistically significant differences among the lymphatic reflexology, relaxing reflexology and rest groups [2]. These studies showed that reflexology is can be used as one of the effective techniques in physical therapy treatments, because it showed an effective results in treating the symptoms of the common diseases that been treated with physical therapy such as pain in cancer, osteoarthritis, LBP, and MS. Reflexology also shows it is effectiveness in pregnancy and childbirth. Women who actively choose to receive regular reflexology during pregnancy have been shown to gain a degree of relaxation that indirectly impacts on the developing fetus [6]. Some women may have been attending for treatment prior to conception and may even have sought help for infertility, subfertility, or premenstrual syndrome. Anovulatory infertility may be resolved through the stimulation of the reflex zones for pituitary gland and ovaries whilst general relaxing reflexology can be helpful where stress and anxiety appear to be contributory factors. Stress, tension, anxiety and fear affect every pregnant woman to a greater or lesser degree [6]. Reflexology can have profound benefits at this time, although whether this is due to physical effects of reflexology, the therapeutic value of human touch or the psychological effects of interaction with the therapist is debatable. Specific physiological disorders of pregnancy can be treated effectively with reflexology or reflex zone therapy. Some physiological conditions respond with just one or two treatments of no more than 10 minutes duration, with no further appointments being necessary. These include nausea and vomiting, constipation, carpal tunnel syndrome and heartburn. Also reflexology can be extremely relaxing, pain relieving and psychologically comforting during labour. Following delivery, reflexology can be used to treat women with physiological disorders of the puerperium, including constipation, haemorrhoids, perineal discomfort and inadequate lactation. Relief from ongoing discomfort following epidural anesthesia, such as backache, neck pain or headache, can also be obtained (Tiran 1996) [6]. 3. The contraindications for reflexology are [10]: If the patient has contagious or acute infectious disease recent surgery of malignant tumor foot wounds, burns or infection deep vein thrombosis/phlebitis pregnancy (treatment should be done with caution to certain reflexes and caution should be taken particularly in the early stages of pregnancy) avoid reflexology when you are using alcohol or street drugs or strong pain medication such as morphine recent or healing fractures active gout affecting the foot osteoarthritis affecting the ankle or foot or severe circulation problems in the legs or feet should seek medical consultation before starting reflexology 4. The recommendations for developing and integrating reflexology in clinical practice [6]: Evaluate hospital provision of reflexology for benefits and find the best ways of delivering treatment through quality research and audit activities. Presentation of conference papers, workshops and poster sessions on complementary therapies, such as reflexology, covering various specialties. Share best practice in reflexology in journals covering a wide range of clinical areas, e.g. intensive care, accident and emergency, and orthopaedics Establish and/or practice in complementary therapy/reflexology networks and specialist interest groups to obtain support and share best practice. Establish and/or practice in a Trust or hospitals Complementary Therapy Committee Ensure that only qualified complementary therapists with experience in managing patient care in the private and public healthcare sectors are employed Support practitioners to complete courses in specialist application Provide and support supervision and management arrangements for all practitioners providing reflexology, for example, by employment of a Complementary Therapy Coordinator/Practitioner 5. Conclusion: Reflexology should not be considered a cure for any condition. It is used to relieve or reduce symptoms, problems, and stress affecting the body. Health professionals should be cautious about a reflexologist who claims that this is a valid way of assessing health or for treating diseases. Even reflexology is not a cure but is a technique to reduce the symptoms associated with chronic diseases. From my perspective, I think that physiotherapist should become familiar with the benefits of reflexology and master this amazing technique so they can use it in their treatment sessions; because it is effective in reducing anxiety and pain in cases of chronic diseases such as cancer. There is very little researches about the effects of reflexology. As such studies were set up to examine the effects of reflexology treatments on cancer, arthritis, LBP, MS and pregnancy symptoms, the results were qualitative and quantitative and showed that there are a number of areas of possible benefit for pati ents with these chronic diseases. But a larger scale study with a longer time frame is needed for a full evaluation of these effects. At the end, I would like to clarify that physical therapy is different from reflexology, but that does not prevent to use it in the treatment of some chronic conditions that are difficult to relief their complicated symptoms by using only physical therapy techniques.

The Catcher in the Rye - J.D. Salinger as Holden Caulfield :: Catcher Rye Essays

The Catcher in the Rye - J.D. Salinger as Holden Caulfield The Catcher in the Rye, by J.D. Salinger, is home to the protagonist Holden Caulfield. There is no coincidence that he holds a striking resemblance to the author of the novel himself. Salinger seemed to have a similar childhood as Holden describes in The Catcher in the Rye. Both men also seemed to have a certain fascination with younger children, especially younger women. J.D. Salinger based one of his most famous characters, Holden Caulfield, on personal experience. Holden's story in The Catcher in the Rye begins with Holden at his school, Pencey Preparatory, which is a boarding school. He was sent there by his parents, who seemed to be withdrawn from his life. Similarly, Salinger's parents sent him to Valley Forge Military School, where he had a neighbor who always seemed to be barging in, showing a resemblance to Ackley. The reader learns that Holden is the son of wealthy parents from New York. It turns out that J.D. Salinger was also born in New York to upper-class parents. It seems as though Holden Caulfield's childhood is an identical match to that of J.D. Salinger's. Salinger had a deep love and fascination with young children, especially young women. In the 1970s, Salinger maintained a close connection with an eighteen year-old girl, Joyce Maynard, who eventually moved in with the author. J.D. Salinger continued to have many relations with younger women, much like this one. His fascination with young women is reflected in Holden, who has a similar mind-set. Even as a seventeen year-old, Holden is infatuated with his perception of Jane Gallagher as a little girl. It is this picture of innocence that Holden is in love with, and not what Jane is like now. The concept of, "the catcher in the rye," itself projects his interest in children. He day-dreams about standing at the edge of the rye field catching any children that are too close to the edge of the cliff.

theory of constraints :: essays research papers

Background Eastern Financial Florida Credit Union is the largest credit union in South Florida. The last three years have been intensive with rates dipping to there lowest in 40 years. Because of this, 92% of mortgage holders had economic reasons to refinance.   Ã‚  Ã‚  Ã‚  Ã‚  Eastern exists to achieve goals to improve member service, work performance and increase profitability; however, certain factors limit their capacity to manage constraints and they needed help. Eastern Weak Links Eastern needed help because they were faced with a bottleneck/constraint of having more loan applicants than they were able to timely process so they decided that the problem can be eliminated by implementing Theory of Constraints (TOC) drum-buffer rope and five focusing steps. Other weak links that need to be addressed are:  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Inability to commit to closing dates  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  A lot of work in process in the system  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Lead times too long  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Constantly shuffling priorities  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Too much expediting  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Stressful work environment  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Difficulty in responding to urgent member requests  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Overtime doesn’t increase profits  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Outsourcing doesn’t solve the problem TOC is based on the fact that all businesses operate with constraints or bottlenecks, which disable the progress or success of a company. By identifying the bottleneck, the entire operation is strengthened. Drum, Buffer, Rope (DBR) Eastern uses this view in managing constraint along with the five steps. Using DBR assures that the company is running the right thing at the right time. Five Focusing Steps  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Identify  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Exploit  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Subordinate  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Elevate  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Inertia Identify/Drum Since we just reviewed the weak links, we must seek and destroy the bottleneck. Identifying the drum/constraint is critical to the theory of constraints. Eastern identified the constraint to be in the underwriting department. Exploit/Buffer To exploit the constraint, Eastern puts all efforts toward maximizing the area that is causing the problem, which is underwriting. Eastern provided enough work in process files to protect the systems deliverables (closing and delivery dates), which is related to the buffer. The buffer tells two things: when too much material is in the buffer and not enough. The system assures that underwriting is protected with work in process files, which is the amount of material in the buffer. This pre-determined amount of work is the rope. Subordinate Subordinating involves training others to improve the constraints area; Eastern provides the protection for all resources to underwriting and provides cross training and backups to the department; this assures that the constraint is operating continuously.

Learning Team IRAC Brief Essay

Learning Team B was tasked to study the IRAC method of case study analysis, and select one legal case from a current event that has taken place within the past two years relevant to this week’s objectives. After selecting a current case, Learning Team B prepared a case brief using the IRAC method. Learning Team B selected the United States v. Jones case, which was decided January 23, 2012. Learning Team B was also tasked to provide an explanation of how the legal concepts in the United States v. Jones case could be applied within a business managerial setting. The government issued a warrant to place a Global Positioning System on the personal vehicle of Jones to track any unlawful behavior. For 28 days, the government monitored the vehicle and â€Å"it subsequently secured an indictment of Jones and others on drug trafficking conspiracy charges† (â€Å"United states v.,† 2012). The issue is that a violation of the Fourth Amendment may be in question. The questio n in this case is whether or not the vehicle that was fitted with the GPS is considered real or personal property. Also how is the vehicle subject to government surveillance only on public property? Could the vehicle be subject to the real or personal property laws protected under the Fourth Amendment? The question remains if the vehicle can be searched using the GPS only part of the time. The court’s ruling still does not clearly define what the fourth amendment covers as real or personal property. The definition of the Fourth Amendment is not completely clear on exactly what the real or personal property is defined as or if it is reasonable expectation of privacy as defined by society or a court of law. The law â€Å"protects reasonable expectations of privacy, but the Supreme Court has refused to provide a consistent explanation for what makes an expectation of privacy ‘reasonable’† (Kerr, 2007, p. 503). The Fourth Amendment can be applied to a business managerial setting by protecting workers rights to privacy somewhat. Any use of work property, including e-mail and Internet is subject to inspection by the company. There is a reasonable expectation of privacy in the workplace if an employee has an office. If the employee is in the  front of the work environment conversations or anything in plain view can be subject to police search. According to â€Å"Surveillance Self-Defense† (2013), â€Å"A big question in determining whether your expectation of privacy is ‘reasonable’ and protected by the Fourth Amendment arises when you have ‘knowingly exposed’ something to another person or to the public at large† (Reasonable Expectation of Privacy). If a person is exposes intended personal information or property to a third party that reasonable expectation of privacy is no longer valid. The â€Å"Fourth Amendment is part of the Bill of Rights,† and the â€Å"Bill of Rights is the first 10 amendments of the United States Constitution.† The â€Å"Fourth Amendment protects the rights of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures† (Gatewood, 2013, p. 1). The government can use â€Å"GPS to track an individual movement† if they believe a crime have been committed. If law enforcement wants to obtain a warrant for â€Å"a GPS device to be installed† on an individual car, he or she must be able to convince a judge that a crime has been committed. They must also provide the judge with information about the place that will â€Å"be searched, and the† individual â€Å"or thing to be seized† (Hughes & Burton, 2013, p. 1). In this court case, â€Å"the agents obtained a warrant, but they did not comply with two of the warrants restrictions. First, they did not install the GPS device within the 10-day period that was required by the provision of the warrant.† Second, the â€Å"GPS device supposed to be installed in the vehicle in the District of Columbia, as required by the condition of the warrant.† The â€Å"government installs the GPS device on the vehicle in a public parking space in Maryland† (McKenzie, 2002, p. 1). According to McKenzie (2002), â€Å"the vehicle is an effect as the term is used in the Amendment, and this is a violation of the Fourth Amendment.† An organization that use any form of GPS device on an individual vehicle would be violating the Fourth Amendment.† The â€Å"Fourth Amendment† was implemented to safeguard the rights of citizens, and to make sure that his or her â€Å"privacy is not violated† in any way (McKenzie, 2002, p. 1). A public management can â€Å"conduct a mixed-motive search of an employer’s workplace, seeking to discover evidence of worker misconduct, as well as evidence the worker has committed a crime.† For example, a â€Å"search of a computer of a worker who has been downloading child pornography implicates both personnel misconduct and criminal concern.† â€Å"Courts assessing whether to apply the O’Connor reasonableness standard or the more traditional Fourth Amendment probable cause and warrant requirements of these mix-motive searches have applied O’Connor, reasonableness standard.† Certainly, â€Å"as explained by the United States Court of Appeals for the Fifth Circuit, O’Connor’s† objective of â€Å"ensuring that an efficient workplace should not be frustrated simply because the similar misconduct that violates a government management’s rule, and it is also illegal† (Koster, 2007, p. 1). A community employer can conduct searches related to the workplace â€Å"such as to find a missing file or to investigate workplace misconduct,† in compliance with the â€Å"Fourth Amendment without probable cause or a warrant.† A job-related search is â€Å"constitutionally† allowable â€Å"as long as they are reasonable expectation of privacy.† Furthermore, â€Å"even if the search does infringe on a worker’s reasonable expectation of privacy, the search will deemed reasonable in accordance with the Fourth Amendment it is justified as its inception and permissible in scope† (Koster, 2007, p. 1). In George Orwell’s 1984, the citizens of the dystopian, totalitarian country of Oceania are subjected to a grim reality of constant government surveillance. In difference, technology is necessary to fulfill Orwell’s nightmare is far closer to fact than fiction. For example, the smart phone while using its GPS function is an indispensable component for numerous road trips; this global device has many of the same capabilities as 1984 feared telescreen. In the United States v. Jones, the Supreme Court of the United States concluded that police violated the Fourth Amendment of the United States Constitution when they attached the GPS-enabled tracking device to the defendant’s vehicle and used it to monitor the car’s movements for 28 days (Maryland Law Review, pg. 998). Jones highlights two uniquely prescient  concerns: The impact of modern information-sharing technology on individual privacy, and what limits ought to be placed on Law enforcement from using such technology unrestricted by physical boundaries (Maryland Law Review, pg. 999). The U.S. Supreme Court affirmed the judgment of the lower court and held that without a warrant, the installation of the GPS tracking device constituted an unlawful search under the Fourth Amendment (â€Å"United states v.,† 2012). The government had argued a person did not have a reasonable expectation of privacy on public streets but the U.S. Supreme court rejected this argument. The U.S. Supreme court ruled a person does have a reasonable expectation of privacy on public streets regardless of how the GPS tracking device is placed on the person’s vehicle. The U.S. Supreme Court also ruled that today’s surveillance technology is very advanced but still creates a physical intrusion into a person’s reasonable expectation of privacy protected under the Fourth Amendment (â€Å"United states v.,† 2012). This ruling is very important in today’s business world as technology rapidly advances. The current generation of workers is very comfortable with advanced technology but still have the basic expectations of privacy that workers had 20 years ago. Companies can track email conversations, locate company smart phones using GPS technology, locate, and monitor routes of company vehicles, and even video tape activity at their locations. It is important that an organization brief and ensure each employee acknowledges the reasonable expectation of privacy policies. If a company issues a smart phone to an employee and employ GPS tracking on the phone, the employee must be informed his or her smart phone will be monitored. If a company installs GPS tracking devices on their vehicles the driver of that vehicle must be informed his or her route and movement is subject to company monitoring at all times. If a company video monitors its employees, employees must sign an acknowledgment under standing their movement with the organization is monitored and recorded during the business day. Advanced technology is a tool to reduce fraud in the workplace but cannot violate an employee’s right to privacy under the Fourth Amendment. References Gatewood, J. (2013).
