Ethics, No Secrets Policy and Counselor Values Essay Example
Morals, No Secrets Policy and Counselor Values Essay Visual cue Responses Julie Sanders * I trust it is unscrupulous for the advisor to uncover anything said in singular directing with the spouse. She didnââ¬â¢t address a ââ¬Å"no secretsâ⬠strategy in the educated assent. Offering this data to the spouse without his consent is deceptive. In marriage mentoring the ââ¬Å"no secretsâ⬠strategy should be tended to and clarified in the educated assent. Since she didn't have an approach concerning this, she is limited by secrecy which ought to have been in her educated assent. It isn't the activity of the instructor to ingrain his/her qualities onto a customer. The advocate shold attempt to stay as nonpartisan as could reasonably be expected. Regardless of whether the spouse feels the extra-conjugal relationship is upgrading the marriage, his significant other still doesnââ¬â¢t think about it, and he is by all accounts the just one profiting by the issue. The advocate ought to stay as impartial as conceivable while talking about this with the spouse and urge him to bring this up in a conjoint meeting. It isn't the therapistââ¬â¢s choice to make since she didn't have a ââ¬Å"no ââ¬Å"secrets strategy set up. I donââ¬â¢t figure the advisor ought to ââ¬Å"persuadeâ⬠the spouse to surrender the undertaking or bring it up in joint guiding. As I would see it that is as yet forcing her qualities on the customer. All things considered, I do think, it could be said, that the advisor is conspiring with the spouse. Notwithstanding, she is answerable for the circumstance by not obviously expressing classification and ââ¬Å"no secretsâ⬠in her educated assent. * According to Corey (p. 98) advisors ought to have a procedure of self-assessment to find their own inclinations, convictions and qualities. I think it is deceptive to allude a customer in view of a therapistââ¬â¢s individual convictions. Saying that, if the guide has unequivocally held convictions and qualities, they ought to be tended to in the educated agree and disclosed to clientââ¬â¢s before the directing procedure starts. This would give the advisor reason for referral. Since the instructor is limited by secrecy, she can't tell the spouse of the husbandââ¬â¢s undertaking, however in the event that the guide tended to valueââ¬â¢s predisposition in the educated assent, she can offer that as a purpose behind referral. It isn't the counselorââ¬â¢s work, nor is it moral for the advocate to educate the spouse regarding the undertaking. * I donââ¬â¢t trust it is to the greatest advantage of the first customer (the spouse) for the mentor to offer marriage mentoring to the couple. The situation doesn't address the preparation of the guide in this field. On the off chance that I were the mentor, I would keep on observing the spouse, managing his issues and allude the couple to a marriage mentor.

Iââ¬â¢ll be glad to talk about and answer any inquiries in regards to these territories. In the start of the assent for is a segment I might want to bring your consideration the motivation behind treatment, strategies, the chance of a negative result, potential advantages, expense structures, your privileges and obligations and furthermore both of you can pull back whenever (Corey, p. 474). I have a ââ¬Å"no secretsâ⬠strategy. Since you are here for coupleââ¬â¢s advising I feel you should be transparent with one another. On the off chance that one of you shares a ââ¬Å"secretâ⬠with me exclusively that I may feel important to share, I will choose if it should be imparted to your life partner. iii) I won't share my qualities with you in regards to marriage or extramarital issues I donââ¬â¢t figure it would be moral since it could influence your dynamic, and how I for one feel about an issue isn't the issue being tended to. For your eventual benefits, I feel it is best that I stay as nonpartisan as could reasonably be expected. v) In the start of the guiding procedure alongside educated assent I would address the issue of walloping an accomplice. The customers and I would address the issues engaged with being straightforward instead of being ââ¬Å"brutallyâ⬠legitimate in a manner that could cause hurt. In the event that subsequent to talking about the impacts of a trap, it happens in any c ase, I would ask the ââ¬Å"ambusheeâ⬠how that affected them and the ambusher the thinking behind the ââ¬Å"attack. â⬠Hopefully this would empower a sound, fair and significant discourse between the two.

The History of Computer Programming Research Paper
The History of Computer Programming - Research Paper Example PC programming began in the nineteenth century, however researchers had begun planning a few gadgets, for example, number crunchers for different purposes before this period. Charles Babbage structured the principal programmable PC in 1835, called the Analytical Engine. The Analytical Engine could be modified to take care of computational issues. Ada Lovelace structured the principal program for the Analytical Engine and imagined the programming circle and subroutine. Herman Hollerith developed the idea of information recording on machine discernible media in the late 1880s. He utilized punched cards and created two machines to be specific the tabulator and keypunch to process the cards (Campbell-Kelly and Aspray 45). During the 1940s, PC coding was done physically and afterward went into the framework as the frameworks were moderate and had constrained memory. PC programming dialects, for example, Plankalkul, C-10, and ENIAC were created. A machine called Robinson was created in 1940 by the British so as to decode the messages scrambled utilizing the Enigma machine by the German military during World War II. Z3 was planned in Germany in 1941 by Konrad Zuse. He began creating Plankalkul (Plan Calculus) in 1945, which was the principal algorithmic PC programming language. His machines were pulverized during the World War II and just the Z4 endure. Researchers from IBM and Harvaerd planned a programmable PC in 1944 called Mark I (Oââ¬â¢Regan 124). In 1945, John Von Neumann imagined the ideas of ââ¬Ëshared-program techniqueââ¬â¢ and ââ¬Ëconditional control transferââ¬â¢. The mutual program procedure expressed that mind boggling guidelines should control straightforward equipment rather than the basic equipment being wired for each program. The restrictive control move empowered the improvement of circles with IF, THEN, and FOR proclamations. This idea additionally recommended that little code squares could take any arbitrary request rather than the means requested sequentially. Von Neumann design was imagined and it empowered the

Think Personal Development is Optional Think Again
Think Personal Development is Optional Think Again Many of my blog articles are about topics that might fall under âpersonal development.â These articles are often my favorites to write, and yet thereâs sometimes a voice in my head saying, âBrenda, your readers want to read about something practical! Donât go overboard here or get too âwoo-woo.â An article I read today gave me encouragement to keep writing these âself-growthâ or âpersonal developmentâ articles. August Turak, author of Business Secrets of the Trappist Monks, wrote a piece for Forbes that spoke to me strongly. In it, he lamented that the business world and much of society compartmentalizes personal growth as if itâs something we do on the side to get somewhere or get business resultsâ"including becoming a better leader. On the contrary! Turuk argues vehemently that the essence of leadership is to use every opportunity as a means for personal growth. Become a CEO to grow yourself rather than growing yourself so you can get that CEO position. Focus on your higher mission or spiritual developmentâ"and success in other aspects of life will be a natural by-product. He asserts, âThe reason you were born is to become the best human being you can possibly be.â So make personal development your mission, rather than using it as a âmeans to a more limited end.â Turak holds up the example of Fyodor Dostoevsky, who wrote some of the worldâs most classic Russian novels. Said Dostoevsky, âMan is a mystery. If you spend your entire life trying to puzzle it out do not say that youâve wasted your time. I occupy myself with this mystery because I want to be a man.â I personally must cop to doing personal growth trainings in part so I will succeed in business, in relationships, in my health, and in every aspect of my life. I have also done what Turak advocates so strongly: taken on new ventures and new relationships with the intention of having those challenges contribute to my growth. Even within my personal development circles, such as my learning group with the Wright training Iâm in right now, I take risks and stretch myself in every way I can. That is the fastest path to growth and to being a fully realized human being. This journey is never over, and the puzzle will never be solved. Thatâs what makes it so worthwhile, regardless of whether I become as successful in business as the Trappist monks. I, for one, intend to keep exploring the mystery.

Pros and Cons of Managed Care - 955 Words
Pros and Cons of Managed Care Some of the pros for managed care are; Preventive care ââ¬â HMOs pay for programs, they are set up and are intended at keeping one healthy (yearly checkups, gym memberships, etc.)The idea is, so they won t have to pay for more costly services when and if one gets sick. Lower premiums ââ¬â Because there are limits set as to which doctors one can see and when one can see them, HMOs charge a premium and usually they are lower premiums. Prescriptions ââ¬â As part of their precautionary retreat, most prescriptions are covered by HMOs for a co-payment that also can be very low. Fewer unnecessary procedures ââ¬âdoctors are given financial incentives from HMOs , to provide only needed care, so doctors are less likely toâ⬠¦show more contentâ⬠¦Those up on the hill have responded with a charge of state and national bills pointed at bringing in a booming healthcare industry that s pretty much free-for-all. For their part, the networks don t see what the entire objection is about. They say productiveness and peoples request will keep their guidelines just and within ones means. The networks are trying not only for cost, but also for class and peoplesââ¬â¢ satisfaction. It s a patron service industry when you get right down to it. The network points to their absolute success in bringing down costs and keeping the mass of network enrollees happy. Each month people across the nation join a network, so it s plain that, Network care is here to stay in one shape or another. Those against and those rooting for that of managed care agree that the existence of unconstrained health care on demand is declining. As health care costs push very high yearly, some say it s time for all to comprehend that the medical healthcare industry has financial restrictions just like any other industry. People have been brought up to believe that health care is an entitlement, says (Jeanne Holland, executive director of Northeast Physicians-Hospital Organization) at Beverly Hospital. They think Life, liberty, the pursuit of happiness and health care on demand. Consumers need to change their thinking.

The language is a culmination of many words from many pre-existing languages around the world, but specifically influenced by the Old Norse language of the Vikings. After the Normans conquered, where we had Old English, it transformed into what we called Middle language, which was borrowed mostly from their language, as far as spelling and vocabulary are concerned.

Physics investigation- stopping distance Essay Example
Physics investigation- stopping distance Paper Introduction In my investigation I intend to gather enough evidence and explanation to see if and how the mass of a ball will affect its stopping distance. I will carry out a series of tests starting with changing the mass of the ball then changing height which its dropped from. Predictions I predict that the mass of a ball will most defiantly affect the distance it takes to stop because as the mass increases, the amount of friction with the surface will increase which will slow down the ball sooner. I believe if the mass of the ball is doubled the friction with the surface its on will double and therefore half the distance taken to stop. Equipment For my investigation the equipment I will require is: * A ramp and stand ( 1 metre long) * Carpet (2 by 0. 5 metres) * 2 balls of different masses but same size ( ball 1, 2. 8g and ball 2, 44. 9g) * 2 metre rules My setup My setup is pretty simple I will use a ramp with a rule along it and some carpet for the balls to roll along I will then use another rule to measure the distance taken to stop. When I first set up my equipment the balls where rolling around everywhere, to overcome this problem I decided to curl the carpet into a half bowl shape the balls then rolled smoothly down the ramp and along the carpet. Procedure Firstly I will drop the lighter ball 1, and measure its stopping distance and record this result; I will then drop the same ball another 4 times and record those results. I will average the 5 repeated results in order to gain a fair distance for the stopping distance of each ball. I will then repeat this with ball 2 and accumulate an average. All other variables for now will be kept the same (i.e. gradient of ramp, height dropped from) Test 1 In my first test I will be testing ball 1 of radius 2 cm and mass of 2. 8g, against ball 2 of radius 2 cm and mass of 44. 9g. I will be dropping the ball from 30cm up the ramp with gradient of 24. 4i , my results are: Ball 1 (cm) Ball 2 (cm) 1 115 83 2 99 84 3 108 84 4 114 87 5 112 88 Average 109. 6 85. 2 Analysis My first test supports my prediction that the mass of a ball does affect the distance that it takes to stop, although ball 2 is over 16 times heavier so I would have expected the stopping distance to be shorter. Test 2.

I decided to use a toy car and change the mass of the car by adding weights to it, this will mean that the coefficient of friction will be the same for all my tests. New equipment à toy car weights à blue tac (to attach weights to car) Test 3 Here I will be using the toy car of mass 17. 4g, and I will add 17. 4g so the cars mass will have doubled and I will further use the car plus 100g to see how this affects the stopping distance, my results are. Car no added mass (cm) Car plus Analysis From these results it is clear that my prediction is only partially correct as the mass of an object does affect its stopping distance but the relationship is not as linearly as I expected, as the mass is doubled the stopping distance is not halved this is due to the momentum that the object gains, when more mass is added the object gains more momentum proven with the momentum formulae momentum = mass velocity, so the object will travel feather with more mass, this will explain why when the mass of my car had an extra 100g it travelled a further 77. 2 cm. Although its not that simple because we have to take into account friction, as the mass increases the gravitational pull of the earth will increase which in turn increases the amount of friction between the car wheels and the surface they roll on and a greater friction will slow down the car and reduce its stopping distance, this will explain why when I added only 17. 4g the stopping distance was less . In theory there should be a certain mass that when added to an object the stopping distance will not change as the amount of extra momentum it gains will be cancelled out with the increased friction. I will extend my investigation to try and work out this quantity of mass. Test 4 Here I will again be using a toy car and I will change the mass using weights from 20g up to 90g, dropping the car from a height of 10cm and gradien Distance taken to stop (cm) Analysis. Analysing my results soon after the test I noticed a pattern within my results, although at mass 80g this was not true I decided to repeat the 80g run and found that the distance was actual higher and fit in with my other results. Total mass of car (g) Plotting a graph of my results shows the trend more clearly. As you can see from 20g 40g the stopping distance of the car decreases this is where the extra mass produces more friction than momentum, after this from 40g 90g the stopping distance increases where the momentum is now greater than the friction, due to time restrictions I will only be able to make an estimate of the extra mass needed for friction and momentum to balance I will base my estimate on the results collected and my graph, the turning point is in between 40g and 50g so I will extrapolate from these to points in order to make my estimate. Conclusion In my experiment I aimed to find out whether or not the mass of a ball affects its stopping distance and if so how does it. I started out thinking I knew what was going to happened and that friction was the only point to consider, after my second test I knew something wasnt right and decided to use the toy car, using the toy car was a massive benefit as I could change the mass so much easier and all other variables where kept the same (e. g. coefficient of friction). It was my first set of results with the toy car when I realised I had to take into account momentum this then explained everything about my previous results and everything fell into place. Feathering my investigation out of pure interest I decided to work out the balancing mass of friction and momentum but due to time restrictions I am only able to make an estimate of 42g due to extrapolating my graph. I enjoyed my physics investigation and wish I had more time to further it more.

When I first set up my equipment the balls where rolling around everywhere, to overcome this problem I decided to curl the carpet into a half bowl shape the balls then rolled smoothly down the ramp and along the carpet. Procedure Firstly I will drop the lighter ball 1, and measure its stopping distance and record this result; I will then drop the same ball another 4 times and record those results. I will average the 5 repeated results in order to gain a fair distance for the stopping distance of each ball. I will then repeat this with ball 2 and accumulate an average. All other variables for now will be kept the same (i.e. gradient of ramp, height dropped from) Test 1 In my first test I will be testing ball 1 of radius 2 cm and mass of 2. 8g, against ball 2 of radius 2 cm and mass of 44. 9g. I will be dropping the ball from 30cm up the ramp with gradient of 24. 4i , my results are: Ball 1 (cm) Ball 2 (cm) 1 115 83 2 99 84 3 108 84 4 114 87 5 112 88 Average 109. 6 85. 2 Analysis My first test supports my prediction that the mass of a ball does affect the distance that it takes to stop, although ball 2 is over 16 times heavier so I would have expected the stopping distance to be shorter.

I decided to use a toy car and change the mass of the car by adding weights to it, this will mean that the coefficient of friction will be the same for all my tests. New equipment à toy car weights à blue tac (to attach weights to car) Test 3 Here I will be using the toy car of mass 17. 4g, and I will add 17. 4g so the cars mass will have doubled and I will further use the car plus 100g to see how this affects the stopping distance, my results are. Car no added mass (cm) Car plus Analysis From these results it is clear that my prediction is only partially correct as the mass of an object does affect its stopping distance but the relationship is not as linearly as I expected, as the mass is doubled the stopping distance is not halved this is due to the momentum that the object gains, when more mass is added the object gains more momentum proven with the momentum formulae momentum = mass velocity, so the object will travel feather with more mass, this will explain why when the mass of my car had an extra 100g it travelled a further 77. 2 cm. Although its not that simple because we have to take into account friction, as the mass increases the gravitational pull of the earth will increase which in turn increases the amount of friction between the car wheels and the surface they roll on and a greater friction will slow down the car and reduce its stopping distance, this will explain why when I added only 17. 4g the stopping distance was less . In theory there should be a certain mass that when added to an object the stopping distance will not change as the amount of extra momentum it gains will be cancelled out with the increased friction. I will extend my investigation to try and work out this quantity of mass. Test 4 Here I will again be using a toy car and I will change the mass using weights from 20g up to 90g, dropping the car from a height of 10cm and gradien Distance taken to stop (cm) Analysis. Analysing my results soon after the test I noticed a pattern within my results, although at mass 80g this was not true I decided to repeat the 80g run and found that the distance was actual higher and fit in with my other results. Total mass of car (g) Plotting a graph of my results shows the trend more clearly. As you can see from 20g 40g the stopping distance of the car decreases this is where the extra mass produces more friction than momentum, after this from 40g 90g the stopping distance increases where the momentum is now greater than the friction, due to time restrictions I will only be able to make an estimate of the extra mass needed for friction and momentum to balance I will base my estimate on the results collected and my graph, the turning point is in between 40g and 50g so I will extrapolate from these to points in order to make my estimate. Conclusion In my experiment I aimed to find out whether or not the mass of a ball affects its stopping distance and if so how does it. I started out thinking I knew what was going to happened and that friction was the only point to consider, after my second test I knew something wasnt right and decided to use the toy car, using the toy car was a massive benefit as I could change the mass so much easier and all other variables where kept the same (e. g. coefficient of friction). It was my first set of results with the toy car when I realised I had to take into account momentum this then explained everything about my previous results and everything fell into place. Feathering my investigation out of pure interest I decided to work out the balancing mass of friction and momentum but due to time restrictions I am only able to make an estimate of 42g due to extrapolating my graph. I enjoyed my physics investigation and wish I had more time to further it more.
