While retirement seems to be a time of little stress. After all, with job stress that’s been endured for decades out of the picture, one may wonder if there even is stress after retirement â€" senior stress can still originate from relationships, finances, and retirement itself, as well as from many other areas of life. Stress Management Methods Useful to Older Adults The following are effective methods of stress management that may be especially conducive to senior health. Meditation Studies on meditation show that it can not only provide relief from stress when it is practiced but can help build a kind of immunity to future stress â€" your stress response may be triggered less often if you meditate regularly. Meditation is also an ideal stress reliever for seniors in that it requires no special equipment or physical ability, can be practiced in a variety of settings, and provides excellent relief from stress. Cognitive Puzzles Solving Sudoku or crossword puzzles, or working on other thinking games can provide mental stimulation akin to ‘brain exercise.’ Because these games require focused concentration, they can provide a helpful distraction for those who tend to ruminate over stressors, plus the benefits of mental stimulation. You can get a lot of mental stimulation by doing the daily crossword puzzle from your local newspaper, or you can go the more high-tech route of playing a portable game like Brain Age for the Nintendo DS. You can also play fun online games. Yoga Research shows that yoga can help promote well-being and improve quality of life in seniors, as well as enhance senior health. It’s also an excellent stress relief tool and can carry other physical benefits. While some forms of yoga have a spiritual component, yoga can be practiced as a purely physical exercise, making it compatible with all faiths. The practice of yoga allows a lot of flexibility, so it’s a good choice for people of all ability levels and fitness goals. Breathing Exercises Breathing exercises are an extremely convenient, fast-acting and effective stress reliever that can be easily adopted by people of any age, including seniors. Wherever you are, it’s possible to diffuse stress with a few deep, controlled breaths. Cognitive Restructuring Sometimes just looking at something a different way can make it seem less stressful. Practice finding the positive in a situation, looking at it from a different angle, or even working with a therapist on a specific situation, and you may find that your stress response is triggered less and less. ‘Cognitive restructuring’ is a clinical term for changing the way you look at things, an important part of cognitive therapy, which has been found to be extremely helpful for a variety of issues, including stress.

Native Americans and the Issue of Alcoholism Essay

Following the European invasion in America, Native Americans came to endure many problems. While some have faded, others still linger on in their lives. The issue of alcohol and alcoholism is one of them. From settlers using it to deceive, to today’s issues on the reservation, alcohol has played a devastating role in the lives of Native Americans. Knowing how the issue of alcohol became such a predominate part of Native Americans lives will allow us to spawn ideas on how to end the problem. Before the colonists arrived in America, Native Americans had little to no knowledge of alcoholic beverages. (â€Å"Stereotypes of Native Americans† par. 1 ). Low alcohol beverages were produced by some tribes but this was only used for ceremonial†¦show more content†¦185). Scientific study also is affected by these stereotype and leads to biased results. Recent studies were found to have false results about the percentage of Native American alcoholics from two reservations. Even though the results of the new study found that the amount of alcoholics on the reservation were fifty percent higher than national averages, it was still considerably lower than the previous study which found up to eighty percent of the men on the reservations were alcoholics (Ham par. 2). With stereotypes becoming so inflated that it affects scientific studies, a higher concern of solving this problem must begin. Native Americans have dealt with many problems after European colonization, and one of the prevalent issues is alcoholism. With the history of alcohol being an invasive and with modern times leading to more cases of alcoholism, it is hard to say when the Native Americans will see the day when their communities are free of this trouble. Section 2: Alcoholism is an issue in many peoples lives. But for Native Americans it has become a very common issues effecting many people. Native Americans also affect more than health, issues like stereotyping and control come into play. Two authors decided to include the effects of alcohol in their works.

Character Analysis of Sammy in John Updikes AP

Sammy: Campbells heroic journey transposed into suburban New England On the surface, the hero of John Updikes much-anthologized short story AP does not seem like a hero on the level of an Odysseus or a Hercules. Sammy is a cashier at a local grocery store. However, when three girls wearing bathing suits enter the AP, Sammy begins to experience a call to action. For the first time in his life, he takes a stand when he feels as if the pretty girls are being treated with a lack of respect. Sammy feels the first stirrings of rebellion within him, as he chafes against the constraints of his life. Campbell divides the three parts of the heros quest into a circular journey of departure, initiation, and return. Over the course of AP Sammy makes his departure into the world of the hero. The first stage of the heroic quest of departure begins with the heros call to adventure. During this first stage, the person is poised at the point in a persons life when they are first given notice that ever ything is going to change, whether they know it or not (Heros Journey: Summary of Steps, MCLI, 1999). This occurs when Sammy sees the three girls walk into the grocery store. His life and his perceptions of his world as a local in a small seaside town will never be the same, nor will his perceptions of himself as a sexual being.

The Role of Perception in Corporate Decision Making Free Essays

Here is an office scenario wherein two senior executives are observing an employee who is a potential candidate for promotion:   At certain times, they both see the said employee just sitting on his chair, lounging, even minutes before the end of office hours.   Often chancing upon the employee during his idle time, Senior Executive A may see this as laziness on the employee’s part.   Senior Executive B views the situation, having kept track of prompt and quality reports done by the employee, as the employee being a fast worker who gets the job easily done and right, not as somebody who is just loafing around. We will write a custom essay sample on The Role of Perception in Corporate Decision Making or any similar topic only for you Order Now This is the fundamental nature of perception.   Senior Executive B saw the employee’s circumstances in another approach from that of Senior Executive A’s.   Even though they both examined the same situation, each one had a different view on it.   The outcome of this observation shall depend upon how the executives had perceived the candidate’s performance.   This is an illustration of how perception plays a part in making decisions on a work setting.   The employee’s likelihood of getting promoted relies on others’ diverse insights. Perception Perception has a role when it comes to decision making on many business situations.   It can impact an organization’s behavior.   Also depending on every person’s background, traits, knowledge, and many other factors, perception can also shape ethical or moral decisions. Definition What is perception?   â€Å"Perception is the process we use to make sense out of our environment by selecting, organizing, and interpreting information from the environment† (Daft, 1997, p. 786). People have varied outlooks on a particular situation in his/her own way.   â€Å"Perception depends not only on the physical stimuli but also on the stimuli’s relation to the surrounding field and on conditions within the individual.   The key word in the definition of perception is individual† (Kotler, 2000, p.173). Impact on Organizational Behavior Because of the different perceptions each individual has on a working atmosphere, it is a necessity for managers to have a profound knowledge of anticipating diversity between the different levels within their organization.   For example:   If a manager only sees his/her staff as a means to an end, just a functioning machine in getting the job done, like without incentives or further trainings, etc., with this kind of perception that the employees may get, how would the employees react to it? There might be a number of them who would not think of it as an issue because they themselves may also only see their work as a means itself to meeting their own needs, financially speaking of earning a salary.   For some, they would like to be recognized and given value as employees, being humanely treated and could perceive their employers as insensitive to both their professional growth and personal welfare. In this case, when this type of perception prevails, it could possibly lead to a chain reaction amongst the employees.   A possible impact could be that the organizational behavior (employees’ performance) is not being concerned about their company’s productivity since the management itself does not look after their issues. How a person perceives others can greatly or minimally impact an organization either in a negative or positive way because people would act in response to it. Another citable circumstance in an office setting with regards to perception and its impact on behavior is rumors.   For instance, there is a new employee who was highly  recommended by an officer of the company.   Some may right away see this as special treatment being given on the said employee.   While others actually get facts and can see  exceptional work being done on the new employee’s part.   Yet, with a number of gossip mongers existing on a work environment, they are going to talk about misleading details.   Now with those who may be unaware of what is actually going on, just basing the events on hearsay, they might perhaps bear some resentment on management or even give it a shot themselves on apple polishing. â€Å"Individual perceptual awareness varies widely.   Recognizing the difference between what is perceived and what is real is a key element in diagnosing a situation† (Daft, 1997,p. 787). Using Perceptive ‘Shortcuts’ Every now and then, several business matters call for immediate decisions.   Some may resort to using perceptive ‘shortcuts’ when judging others.   Positive effects may include a decision being done without delay and can move on to attend to other business matters at hand.   This could result to increase in productivity.   Negative effects consist of hastiness in judgment.   Without studying all the facts and details, one fails to take into account everything that needs to be considered which may be leaving out a factor that could have brought out a different turn of events. The Real World Before a decision is made in real world organizations, an issue is addressed by gathering necessary data or a proposal is prepared for a project they will undertake.   There is an open discussion in order to reach a consensus of opinion (i.e. meeting).   Advantages and disadvantages are weighed out (e.g. project to be considered, acquisition of office equipment).   Strengths and weaknesses are pointed out (e.g. hiring of an applicant, promotion  among ranks).   A good management first makes a thorough study then arrives at a more solid decision this way than in making hasty assessments. Ethical/Moral Decisions How we see things are based on several factors.   People’s views are different because each one has his/her own distinctive background.   What values and beliefs a person has can influence an ethical or moral decision he or she makes.   For example:   A sales agent who proposes to a Human Resources Head the availment of a pension plan for the company’s employees, is also suggesting a share in the commission that he would give to the HR Head when he approves the proposal. If the HR Head perception of the agent’s offer is lucrative to his own pocket and does not see it as harmful to their corporation, viewing the agent’s approach as a normal sales tactic, then this shapes the moral decision he is about to make.   Clearly, this is against business ethics, undisclosed behind-the-scenes negotiations.   The employees, who are not aware of what had transpired between the sales agent and their HR Head, would naturally perceive the outlay in pension plan as a benefit for them.   Now if it was a different matter all together, with an honest HR Head who believes in hard work to earn a living, may see the sales agent as a dubious character and perhaps would choose not to deal with that agent anymore. â€Å"Perception in itself does not always lead to an accurate picture of the environment† (Daft, 1997, p. 562).

Washed by water, keep it level, rotate and release water _ rinsed by distilled water several times, basic burette, with the same operations as acidic. @ Leakage check. Take out the paper in the stopcock, flexible rotation, if it necessary, paint baseline, cannot block the hole. Bind the stopper with rubber ring. Add distilled water till U scale; place the burette vertically for 2 min to observe whether the water face will drop. For base burette, check whether the glass bead and rubber tube can flexibly control the water dropping. Check rubber aging for basic O Solution filling. Rinse the burette with the solution to be added 3 times and let the solution flow out through the stopcock. For acidic burette, quickly open the stopcock and wash the bubble out. For basic, bend the rubber tube 450 upward with left hand. Press and squeeze the point over glass bead With left hand to expel the bubble out of the tip. After that, fill Noah solution into it, drive away the air bubble in the rubber tube and its tip, then adjust the place Of the liquid level to O. 00. Add 0. MM 20. Ml HCI solution with transfer pipette to Erlenmeyer flask, then add 2-3 drops of phenolphthalein indicator, shaking constantly. Extrude the glass ball in rubber tube to make the liquid dropping to Erlenmeyer flask. Pinch the point over glass bead with thumb and first finger of left hand, and control the glass tip with middle finger and ring finger, so as to let out the solution. Dont pinch the glass bead too hard, dont press the rubber tube below or above glass bead. The dropping velocity can be quick at the beginning, but afterwards the operation should be controlled drop by drop and avoiding a current tot liquid. When the base solution drops into the Erlenmeyer flask, part of the solution appears pink, but the color will disappear quickly while shaking the Erlenmeyer flask. Pink color disappears slowly near the end-point, In this period the base solution should be added a drop at a time and allow a half drop of liquid hanging on the tip. It should not fall directly only make it touch the inner wall of the Erlenmeyer flask and then shake. If the pink color doesnt disappear in about half a minute, it means that the end-point is located. Wait a moment, then record the place of the liquid level left in the burette. . Titrate the 0. MM Noah with HCI solution, then C HCI can be Obtained, methyl orange as an indicator. Equivalence point: yellow to orange. Fill HCI solution into burette, drive away the air bubble, then adjust the place Of the liquid level to O. 00. Add C. I M 20 Orin Noah solution with transfer pipette to Erlenmeyer flask, then add 2-3 drops of methyl orange indicator, shaking constantly-operate the stopcock With three ringers Of left hand: thumb ahead, first finger and second finger behind; palm center dont touch the stopcock. Dont pull stopcock outside. Keep the tip of the burette 1 CM rower than flask mouth, and hold the flask neck with first three fingers of right hand to shake it clockwise or anti. clockwise. Titration speed is controlled at 34 drops per second. While approaching titration end, the solution will change color at some point and after shaking, the color will disappear. After that, titrate drop by drop, and when the color change occurs only after 2-3 shaking, control the stopcock to let out halt drop of solution, suspended but not dropped, then wash it into the flask with distilled water; repeat the operation till the color changes and will not disappear. 4. Reading. Bring the burette down trot the stand and hold it by two fingers. Keep it vertical, Read and record the figure when view sight is parallel with the the lowest point of the solution surface. 5. If you have enough time, Titrate again, whether titrate acid or base is k. You must pay attention to the following points: (I) There should not be some air bubbles left inside the tip when the titration is over. (2) The color of the solution after the location of the end-point will disappear because of the effect of CO in the open aim That doesnt mean the acid-base reaction is not complete. (3) During the titration, the base may plash down the upper part of the wall of the Erlenmeyer flask and the last half drop is touched by the wall, so in the immediate vicinity of the end-point it is appropriate to rinse down before completing the titration.
