Investigating the Power of a Diverging Lens Essay Example

Investigating the Power of a Diverging Lens Essay Aim: To find the power of a given diverging lens by using a pre-selected converging lens. Outline: The power of two lenses placed together in line to an object will allow both of their powers to add together.

The power of the converging lens can be subtracted from the total power to find the power of the diverging lens. Variables: Independent: Object distance Dependent: Image distance Control: Object size and shape, power of both lenses, material of both lenses In my pre-tests, I have found that I obtain a reasonable range of results using a converging lens of 10 Dioptres that is larger than the power of the diverging lens therefore giving reasonable results. Method: 1. Set up apparatus as shown in diagram. 2. Adhere the unknown diverging lens to the known, pre-selected converging lens with plasticine ensuring that the plasticine does not interfere with the light i.e. the plasticine does not cover the main central portion of the lenses. 3. Fix the lenses on to the stand with plasticine, making sure that they are perpendicular to the ground therefore the light that falls upon the light will be in line with the normal at the centre of the lenses. 4. Use a piece of card with a triangular hole in it with mesh stuck over the top to be used as the object, one, to block out most of the light to prevent shadows forming, two, it discern whether the image was formed inverted or not, three, the mesh helps me judge when the image is at its clearest. 5. The light, object, lens stand, lens and screen will be arranged in a straight line and kept in a straight line, so that there wont be any undue error caused in the measuring of object and image distances from the centre of the lens, parallel to the metre ruler used to measure the distances. 6. The object distance can then be varied to give difference image distances from which the power of the combined lenses can be calculated. 7. The screen will be held perpendicular to the table to ensure that the measuring is accurate and the image will be formed properly. 8. There will be a range of distances from the lens, which the image will be judged as to being clear and this range will be recorded. 9. Repeat experiment with at least 6 difference object distances 10. Carefully repeat all measurements 11. Use the results to plot a graph to find the power of the combined lenses. Safety: Having considered the safety aspects of the experiment, I am confident that normal safety procedures are adequate and there is no particular danger in this experiment apart from the fact that the light could heat up to rather high temperatures. The electrical equipment should also be handled with more care because of the possible electrical hazard. Uncertainties and Errors Extensive pre-testing proves that the following are likely sources of uncertainty and error. 1. Uncertainties in measurements Length. The metre ruler is accurate to à ¯Ã‚ ¿Ã‚ ½ 0.001 metres, however, the range over which the image is clear vary around à ¯Ã‚ ¿Ã‚ ½ 0.020 metres this value may change as clarity of the image may change with distance. A range can be measured, but those upper and lower boundaries will also be affected by the error in measurement by the ruler therefore if the range is à ¯Ã‚ ¿Ã‚ ½ 0.020 metres, the range including measurement errors is à ¯Ã‚ ¿Ã‚ ½ 0.021 metres. 2. Errors in the Experiment Distance between lenses and the thin lens formula. Errors will occur because the light will converge inside the space between the two lenses, therefore the focal distance will be incorrect. If the light converges between the lenses, then the light that hits the second lens will have converged and therefore the focal length will change, as shown in the diagram, Large Gap Small Gap There must always be a space between them, because they are not one lens the only possibility is that if both their curvatures were equal, then their powers would cancel out (the converging lens has a positive power, diverging has same power, but negative) and then the light emitted would be parallel, therefore no image will be formed at any point and the power cannot be calculated. Also, the thin lens formula is only an approximate model to finding the power of thin lenses, this is because the formula applies 100% accurate only to a infinitely thin lens, but because all lenses will have a certain thickness, the formula can only give a good approximation. The thinner the lens, the better the approximation given by the formula. Errors in judgement of which position creates the clearest image is the probably the most significant error in the entire investigation because there may be a range of positions where the image appears to be clear. Therefore a range of values will be taken as the position for the maximum clarity of an image thereby reducing the error that could be involved and also means, graphically, that a best fit line can be drawn within the error bars that fit the hypothesis. Analysis After collecting all the results, I can plot the range of values of each different object distance with their corresponding image distance. To draw this graph and obtain a linear relationship, I can rearrange the thin lens formula to the linear graph form y = mx + c where y and x are variables, m is the gradient of the line and c is the y-intercept. Where and but, because the formula can also be arranged thus, That means that will be both the y-intercept and the x-intercept, therefore giving a graph like this, where both intercepts are equal to the power (Power = reciprocal of focal length, P = f-1) I will also include error analysis, which is shown here with a set of pre-test data using a converging lens of 10 dioptres, TABLE 1 Object Distance (m) Minimum Length for Clarity (m) Maximum Length for Clarity (m) Mean Length for Clarity (m) Subsequent Power of Diverging Lens (D) Error in measurement (m) 0.550 0.660 0.700 0.680 -6.71 à ¯Ã‚ ¿Ã‚ ½ 0.001 0.500 0.750 0.790 0.770 -6.70 à ¯Ã‚ ¿Ã‚ ½ 0.001 0.450 0.830 0.870 0.850 -6.60 à ¯Ã‚ ¿Ã‚ ½ 0.001 0.400 0.930 0.970 0.950 -6.45 à ¯Ã‚ ¿Ã‚ ½ 0.001 0.350 2.230 2.270 2.250 -6.69 à ¯Ã‚ ¿Ã‚ ½ 0.001 Then the error in the object, image minimum, image maximum and image mean length will be à ¯Ã‚ ¿Ã‚ ½0.001 but because the lengths are made into reciprocals, their errors become neither absolute nor percentage, therefore to calculate it, the maximum and minimum values must be used, so there will be 2 more columns where the error is added to the values, TABLE 2 Absolute Minimum Length for Clarity (m) Absolute Maximum Length for Clarity (m) 0.659 0.701 0.749 0.791 0.829 0.871 0.929 0.971 2.229 2.271 If the values themselves are used to calculate the power of the diverging lens mathematically, it would be as such, including Table 1 TABLE 3 Lower Boundary Power (D) Upper Boundary Power (D) Mean Power (D) Error of Mean Power (D) -6.670 -6.750 -6.710 à ¯Ã‚ ¿Ã‚ ½0.040 -6.670 -6.700 -6.685 à ¯Ã‚ ¿Ã‚ ½0.015 -6.570 -6.620 -6.595 à ¯Ã‚ ¿Ã‚ ½0.025 -6.420 -6.460 -6.440 à ¯Ã‚ ¿Ã‚ ½0.020 -6.690 -6.700 -6.695 à ¯Ã‚ ¿Ã‚ ½0.005 Average -6.625 à ¯Ã‚ ¿Ã‚ ½0.021 Therefore the power of the diverging lens is -6.625 dioptres with an error of à ¯Ã‚ ¿Ã‚ ½ 0.021. The graph can be drawn including these errors, and it makes it possible to draw a graph with a linear relationship where the x and y intercepts are equal within the range of the error of the results to find the correct power of the diverging lens. See graph of pre-test results. From the graph, the intercepts are at 3.3 D, therefore the resultant power of the combined lenses is 3.3 D. The pre-selected lens is 10 D, therefore, 10 + d = 3.3 ? d = 3.3 10 ? d = -6.7 D So, the power of the diverging lens is -6.7 dioptres.

10 Description Essay Topics on Business Communication

10 Description Essay Topics on Business Communication If you are tasked with writing an essay on business communication, you must substantiate all of your claims with facts. Below are some interesting facts that might suit your writing purposes: Business communication is a unique offshoot of regular communication, even though the processes in each and the guiding principles for both are the same. The key difference lies in the situation in which they are applicable. General communication can be used in many situations around the world while business communication deals solely with business activities. There are two types of business activities. The first is internal and the second is external. Internal business activities include the improvement and maintenance of employee morale, the provision of orders to employees, the prescription of methods and business procedures, the announcement of organizational changes and policies, as well as updates for management. External business activities relate to the sale and requisition of goods and services, reports to shareholders, and the creation of favorable workplace environments. In both external and internal business activities the purpose of business communication is to secure action by the person who is receiving the communication. When a business person sends a message to someone else they expect that person to do something upon receipt of the message. This might be the approval of an action, the sending of information, the placing of an order, or any other action. In order to make sure that this happens business communication must rely upon unique language which is direct and concise. The language used for business communication must draw attention, develop conviction, induce action, create desire, or arouse interest. Business communication is typically applied to business documents. Business documents have to meet certain standards so that they are internationally recognized. There are two types of business documents including internal and external. Internal documents are those which circulate inside of a specific organization and often include proposals, memos and reports. External documents are those which circulate outside of an organization. These include reports, letters, and proposals. Some external documents might also include information disclosed to customers, clients, stockholders, media, and customers. Business communication is critical to the success of any organization no matter the size or location of the business. Business communication is part of the external image a company produces. Good business practices help companies achieve their objectives internally and externally through good business communication. In order to survive continual change processes and global environment businesses must change the structure and delivery of communication processes. Global environment for businesses must consider communication issues against a backdrop of technology, ethical concerns, culture, competition, and legal concerns. There are four basic elements to communication. The first is the sender. The second is the receiver. The third is the message. The fourth is the medium used for communication. Communication is therefore defined as the manner through which messages are conveyed to others through a proper and professional Channel.  There are different channels used to convey business communication. The decision to use a specific channel and by extension a specific medium is determined by the purpose of the communication, the ability of the encoder to use that medium, and the effect of the medium to deliver the message. When senders transmit messages a response is expected. Within professional communication responses are generally expected within 24 hours and in some cases within 48 hours during the Monday through Friday work week. If companies specifically state that their departments such as customer service are open on the weekend this response time may extend to weekends as well as weekdays. In any case the response received can be favorable, unfavorable, immediate, or deferred. When writing business communication feedback is essential. Feedback informs the sender that the message was received and the purpose of the message was for filled. Proper feedback in the form of a prompt response issues both parties that active listening is taking place. In many cases among modern communication a deplorable trend has emerged whereby recipients of communication opted not to read the entirety of the message and instead simply gloss over the content picking up a few key details. When this happens the feedback provided reflects upon this laziness. This happens regularly in areas such as customer service or when questions are posed to business policies. When a specific question is asked and the recipient fails to read the question in its entirety it results in the recipient responding inappropriately. The recipient might respond with the wrong answer to a question due to the fact that they read the question incorrectly. Things like this are happening more and more frequen tly within the business community as business communication fades into the backdrop of the online world. Effective business communication revolves around a clear purpose. Just like academic writing, business communication requires planning. The purpose must be planned out prior to writing. Effective communication requires that all people involved in the purpose have a shared responsibility. No matter the level within the company, everyone involved in a single communication is working toward a common goal which means that everyone has a share of the communication process. The needs of the receiver must be kept in mind when communicating in a business fashion. Active listening is an important way to show that both sides are assuming their shared responsibility and review the questions and content in their entirety. Active listening is one of the key elements of modern business communication which is starting to fade away, resulting in miscommunications regularly. Another key aspects related to effective business communication is the control of emotions. Communication and a business settin g requires the ultimate level of professionalism which means that everyone must be motivated to work toward shared goals and doing this means controlling emotions. Part of controlling emotions revolves around politeness. The tone of a communication within the business place is based on the choice of language and it will influence the reaction that the receiver feels. These facts are great, aren’t they? We hope they will suit your paper. Don’t forget to check our 20 topics on business communication for a description essay as well as description essay guide for one of these topics.

Current Events and U.S. Diplomacy Essay Example | Topics and Well Written Essays - 500 words

Current Events and U.S. Diplomacy - Essay Example This was strongly resented by the US. Since the end of the cold war, the relationship between US and Russia unlike in the past has become rosy. The Americans have softened their earlier unrelenting positions and has since become tolerable to the Russians. The policy was dubbed decorative policy and it has made the Americans to drastically change their perceived aggression on Russia to a very cooperative and much philanthropic (Aronson 2001). With regard to these, US have entered into many economic ties with Russia and this has even accentuated the belief that there are cordial relations in the offing. Putin is largely acclaimed to be at the helm of all the gains achieved so far. It is obvious that the relation between US and Russia has grown notches higher since the end of the cold war. Cold war almost led to the fall out between the two countries and these has since been corrected and normalcy is achieved. From the Bush administration to Obama’s, the relationship between the two countries has improved remarkably. For instance, in the Afghanistan case, the US and Russia have joined efforts in finding a lasting solution (Cameron 2005). The US relation with Cuba under the leadership of Fidel Castro for along time has not been admirable, the US initiated economic sanction in Cuba and this has retarded economic gains in the country significantly. There have been constant allegations emanating from both countries against conspiracies (Smith 2008). For example, the assassination of the American president J.F. Kennedy was hinted to have been master minded by the Cuban president, on the other hand the Cuban president claims to have dogged eight times murder initiated by the US. All other countries for along time had at least loose ties with the Cuba economically except the US that has remained defiant in making and signing economic pacts with the Cuba (Smith 2008). In as much as that has happened, US in the year 2000 partially lifted travelling restrictions.

Individual reflective report on business plan Essay

Individual reflective report on business plan - Essay Example The business plan was to be graded according to a rubric; thus, this rubric was considered to be a tool aimed at facilitating the consistency in grading assignment (Martinez, Wells, Peterson, Hannigan, & Stevenson, 2008, 19). Therefore, we took the rubric as the criteria of working on the business plan in order to ensure that it met expected level of quality for the purpose of grading. There were a lot of things that I learnt in the experience from this team work; for instance, I learnt that the team assignment is divided to be assigned to members. I also came to lean than the team leader ensures that member is assigned to the section that they are comfortable with. This was by letting the members decide the section that they were to tackle. I also learnt that there should be a separate section of compiling, editing, proofreading, revising, and submitting (Martinez, Wells, Peterson, Hannigan, & Stevenson, 2008, 19). There was to be one of our members who were to concentrate on this s ection, hence, this was facilitating the covering of all the section of the business plan and work to be credited appropriately. I also learnt the importance of setting dates for checking on the progress with the other members. We used online workspace for updating one another on various tasks of the projects. This helped us to maintain the cohesiveness of the team and ensure that everyone is still doing what was expected. I also learnt that there is the importance in setting the dates for submitting the drafts and the final work for each team member. We also used the time frame for gathering the feedback and ideas from the members before the business plan was finally compiled together. We also ensured that we had enough time for proofreading the business plan before submitting. 2. Process of Idea Initiation: Ideas initiation process began with a stage where members were oriented to the task of coming up with a business plan in a way that created awareness regarding objectives of th e team. Member held a discussion, which was focused on the scope of the task and the approach to undertaking the task (Belbin, 2012, 1). Proceeding to the next stage in the process, members were expected to present their ideas regarding any form of a business plan. In fact, this stage required members to be engaged into a brainstorming session, whereby all the ideas from members were acknowledged. Moreover, they were expected to bend their feeling and attitudes in order to deal with the task that was to be undertaken by the team (Belbin, 2012, 1). On the other hand, members were offered a chance to gather reasonable information regarding any company’s employees, partners, associates, and customers. Nevertheless, during this stage I gained understanding of the performance stage, whereby team members are offered a chance to develop their capacity and interdependence, social skills, and personal relations (Belbin, 2012, 1). Furthermore, this session facilitated development of ab ility to convey ideas and it also assisted the members of the team to acknowledge each member’s contribution. On the other hand, coming up with the business idea required extensive research in the internet in order to gather relevant information; in fact, this facilitated completion of this business plan. This stage gave me the skills to be able to finding journals articles, books, and websites that could provide the relevant information for the research (Martinez, Wells, Peterson, Hannigan, & Stevenson,

Irish Persecution by England Essay Example for Free

Irish Persecution by England Essay Anti-Irish sentiment (also known as Hibernophobia, from Hibernia, the Latin name for Ireland) is traditionally rooted in the medieval period. The first British involvement in Ireland began in 1169, when Anglo-Norman troops arrived at Bannow Bay in County Wexford. During the next half millenium, successive English rulers attempted to colonize the island, pitching battles to increase their holdings – moves that sparked periodic rebellions by the Irish. When did this happen? – The English persecution of Ireland began in the 1800’s with the Act of Union which put Ireland officially under the rule of London. It has continued up until present day but persecution has decreased extremely over the past 300 years. Were any specific groups targeted? – Yes, Catholic Irish were strongly persecuted by English Protestants, which continues into present day. North Ireland seceded but was subject to much violence and was eventually forced back under British control, and still is the center of most of the heated debates of today. How were they persecuted? – Irish people were discriminated against and even murdered by English people. One of the most infamous acts came in 1972, when British paratroopers opened fire on a group of Catholic demonstrators and killed 14 people. The Penal Laws were considered to be the first form of official apartheid issued in the world, dividing and targeting people by their religion. All those not of the Anglican/Lutheran faith including not only Catholics but also Jews, Presbyterians and other types of Protestants were denied rights in relation to property ownership, political participation, and university education. Prohibition on mixed marriages on the basis of religious and racial grounds led to many rallies and riots by the Irish against the discrimination and prejudice they faced. How does this affect people today? Ethnic relations in the Republic of Ireland are relatively peaceful, given the uniformity of national culture, but Irish Travellers have often been the victims of prejudice. In Northern Ireland the level of ethnic conflict, which is inextricably linked to the provinces divergence of religion, nationalism, and ethnic identity, is high, and has been since the outbreak of political violence in 1969. Since 1994 there has been a shaky and intermittent cease-fire among the paramilitary groups in Northern Ireland. The 1998 Good Friday agreement is the most recent accord. What happened to cause it? – The English invasion sparked a lot of anti-English sentiment and led to constant fighting between the two groups. Also, the English exerted complete control and did not help the Irish during the Great Famine between 1845 and 1852, which caused riots and sparked other prejudiced movements and laws. Were there any significant figures in this? English King William III asserted complete control over the Irish in 1691. Eamon de Valera was the leader of the Sinn Fein, a political party which advocated Irish independence. He was almost executed for participating in an uprising in Dublin. Michael Collins was the leader of the IRA (the Irish Republican Army) who fought against the British for the Government of Ireland Act in 1920. Bringing the IRA fight into the international spotlight was Bobby Sands, an IRA member who died while on a hunger strike in a Belfast prison to protest his status as a common prisoner, rather than a political one.

Schizophrenia :: essays research papers

One of the major disorders in the psychology field is schizophrenia, a serious brain disorder. It is a disease that makes it difficult for a person to tell the difference between real and unreal experiences. The word traces back to Greek terms for â€Å"split† and for â€Å"mental functions.†   Ã‚  Ã‚  Ã‚  Ã‚  There are two different types of schizophrenia. One is reactive schizophrenia, which is characterized by the symptoms that are sudden and easily identified. The second type is called process schizophrenia, which develops gradually over a person’s life. The cause of schizophrenia is so puzzling even experts sometimes don’t know what causes the disease. One possible cause for schizophrenia is from heredity. The disease can be passed down from one generation to another. Some researchers also state that it might be caused from the events in a person’s life. The dopamine hypothesis states that schizophrenia may be caused by an excess of certain neurotransmitters in the brain. There are so many possibilities of how schizophrenia is developed that’s why it makes it so impossible to come up with one answer.   Ã‚  Ã‚  Ã‚  Ã‚  A person who has schizophrenia experiences schizophrenia goes through speech disorder, the person will talk and make no sense but will use proper grammar and sentence structure. They also go through hallucinations and delusions, which the person hears voices that, convey instructions about what to think, feel, and do. For example, my uncle suffers from schizophrenia. During the day he will just stare at the sun. When someone asks him why he is staring at the sun he will say, â€Å"They tell me to stare at the sun. It will give you power.† He thinks he is normal but he isn’t. People with schizophrenia don’t realize they have a brain disease. They think they are normal like others around them.   Ã‚  Ã‚  Ã‚  Ã‚   There is no cure for schizophrenia today, but proper treatment can usually control the symptoms of schizophrenia.

Discuss the View That Children Always Suffer When Both Parents Work Essay

As more and more parents try to work at the same time, problem arises: Do their children suffer when both of them don’t have enough time to take care of their children? It seems depends much more on the children, especially their attitudes towards this issue. Children will probably suffer a lot when they are young (below 12 years old) and both parents are at work. This is because they are not old enough to take care of themselves. They need their parents’ support, both mentally and physically. If parents neglect the growth of their children, it is quite possible that their children will get some bad habits from outside (eg, friends, medium), as they are not mature enough to distinguish right and wrong. And they need their parents’ consistent guidance to help them to be the best person they can be. Adolescent will suffer if they are not that self-controlled and both parents work. They can easily run wild when both parents don’t pay much attention about them. Their academic results may be adversely affected. Also, lots of problems will arise, such as skipping school, teen pregnancy and smoking. When both parents work, they may not have enough time take care of their children. And it seems that there is a gap between them and their children as they don’t have enough time to interact with their children. They may not take action in time when their children have misbehaved. And these may be reflected in poorer academic performance by the children, less attention given to their children’s health problem and higher rate of behavior problems of their children. However, if the children are well self-controlled and quite positive about the fact that both of their parents work, it seems to be a good chance for them to become more independent. Children at times will need to learn to do things on their own so it will not be a difficult task for them when they reach adulthood. As they may have already learnt lots of important skills (eg: cooking, self-sufficiency), which they have to learn when they become adults. It also leaves their children a space for them to develop independently when both parents work. To support the family is probably the main reason why both parents work. Actually children are benefited from this. When both parents are employed, they are able to earn more money to raise their children and support the family. They can provide a better living surrounding and a better education environment for their children. Of course, children will suffer when both parents work as they may not get enough care from their parents. However, at the same time, they will also benefit in other aspects, such as better education environment and healthcare system. Compared the gain and loses, I think children will lose more than what they have gained. Who wants to live without their parents when they are young, even though they know it maybe for their own good?

The Return: Shadow Souls Chapter 24

Dear Diary, It's the night before the night of our first party – or rather gala. But I don't feel very gala. I miss Stefan too much. I've been brooding about Matt, too. How he walked away, so angry at me, not even looking back. He didn't understand how I could†¦care for†¦Damon, and yet still love Stefan so much that it felt as if my heart was breaking. Elena put down the pen and stared at her diary dully. The heartbreak manifested itself in actual physical pains in her chest that would have frightened her if she hadn't been sure of what it really was. She missed Stefan so desperately that she could hardly eat, could barely sleep. He was like a part of her mind that was constantly on fire, like a phantom limb that would never go away. Not even writing in her diary would help tonight. All she could write about were painfully tantalizing memories of the good times she and Stefan had shared together. How good it had been when she could just turn her head and know that she would see him – what a privilege that had been! And now it was gone, and in its place was racking confusion, guilt, and anxiety. What was happening to him, right now, when she no longer had the privilege of turning her head and seeing him? Were they†¦hurting him? Oh, God, if only†¦ If only I had made him lock all the windows to his room at the boardinghouse†¦ If only I had been more suspicious of Damon†¦ If only I had guessed he had something on his mind that last night†¦ If only†¦if only†¦ It became a pounding refrain in time to her heart. She found herself breathing in sobs, her eyes tightly shut, clutching the rhythm to her and clenching her fists. If I keep feeling this way – if I let it crush me enough – I'll become an infinitesimal point in space. I'll be crushed into nothingness – and even that will be better than needing him so much. Elena lifted up her head†¦and stared down at her head, resting on her diary. She gasped. Once more her first reaction was to imagine death. And then, slowly, because she was stupefied by so many tears, she realized that she'd done it again. She was out of her body. This time she wasn't even aware of a conscious decision about where to go. She was flying, so fast that she couldn't tell which way she was going. It was as if she were being pulled, as if she were the tail of a comet that was rapidly shooting downward. At one point she realized with familiar horror that she was passing through things, and then she was veering as if she were the end of the whip in a game of Crack the Whip and then she was catapulted into Stefan's cell. She was still sobbing as she landed in the cell, unsure of whether she had solid form or gravity, and uncaring for the moment. The only thing she had time to see was Stefan, very thin but smiling in his sleep and then she was dumped onto him, into him, and still crying as she bounced, as lightly as a feather, and Stefan woke. â€Å"Oh, can't you let me sleep for a few minutes in peace?† Stefan snapped, and added a couple of Italian words that Elena had never had reason to hear before. Elena had an immediate fit of the Bonnies, sobbing so hard that she couldn't listen to – couldn't even hear – any comfort that was on offer. They were doing horrible things to him, and they were using her image, Elena's, to do them. It was all too awful. They were conditioning Stefan to hate her. She hated herself. Everyone in the whole world hated her – â€Å"Elena! Elena, don't cry, love!† Dully, Elena lifted herself up, getting a brief anatomical view of Stefan's chest before she was sobbing again, trying to wipe her nose on Stefan's prison uniform, which looked as if it could only be improved by anything she might do to it. She couldn't, of course; just as she couldn't feel the arm that was trying to encircle her gently. She hadn't brought her body with her. But she had, somehow, brought her tears, and a cold, cable-wire-tough voice inside herself said, Don't waste them, idiot! Use those tears. If you're going to sob, sob over his face or his hands. And, by the way, everyone hates you. Even Matt hates you, and Matt likes everybody, the tiny cruel, productive voice went on and Elena gave way to a fresh gale of sobbing, absently noting the effect of each teardrop. Each drop turned the white skin under it pink and the color spread in ripples outward, as if Stefan were a pool, and she was resting on him, water on water. Except that her tears were falling so fast that it looked like a rainstorm on Wickery Pond. And that only made her think about the time that Matt had fallen into the pond, trying to rescue a little girl who had fallen through the ice, and how Matt hated her now. â€Å"Don't, oh don't; don't, lovely love,† Stefan begged, so sincerely that anyone would have believed he meant it. But how could he? Elena knew what she must look like, face swollen and blotched by tears: no â€Å"lovely love† here! And he'd have to be mad to want her to stop crying: the teardrops were giving him new life wherever they touched his skin – and perhaps the storm inside him had done best, because his telepathic voice was strong and sure. Elena, forgive me – oh, God, just give me one moment with her! Just a single moment! I can bear anything then, even the true death. Just one moment to touch her! And perhaps God did look down for a moment in pity. Elena's lips were hovering over, quivering over, Stefan's, as if she could somehow steal a kiss like this as she used to when he was still asleep. But for just an instant it seemed to Elena that she felt warm flesh below hers and the flick of Stefan's lashes against her eyelids as his eyes flew open in surprise. Instantly they both froze, eyes wide open, neither of them foolish enough to move in the slightest. But Elena couldn't help herself, as the flush of warmth from Stefan's lips sent a flush of warmth through her entire body. She melted into the kiss, and, while keeping her body carefully in the same position, felt her gaze go unfocused and her eyelids close. As her lashes swept against something with substance, the moment swept quietly to an end. Elena had two choices: she could shriek and rail telepathically at Il Signore for only giving them what Stefan had asked for, or she could gather her courage and smile and maybe comfort Stefan. Her better nature won out and when Stefan opened his eyes, she was leaning over him, pretending to be resting on her elbows and his chest, and smiling at him as she tried to straighten out her hair. Relieved, Stefan smiled back at her. It was as if he could bear anything, as long as she was unhurt. â€Å"Now, Damon would have been practical,† she teased him. â€Å"He would have kept me crying, because in the end, his health would be the most important thing. And he'd have prayed for†¦Ã¢â‚¬  She paused and finally began laughing, which made Stefan smile. â€Å"I have no idea,† Elena said finally. â€Å"I don't think Damon prays.† â€Å"Probably not,† Stefan said. â€Å"When we were young – and human – the town priest walked with a cane that he seemed to enjoy using on young delinquent boys more than as a source of support.† Elena thought of the delicate child chained to the huge and heavy boulder of secrets. Was religion one of the things locked away, put behind doors closed one after another in secret there, like a chambered nautilus until almost everything he cared about was inside? She didn't ask that of Stefan. Instead, she said, lowering her â€Å"voice† to the tiniest telepathic whisper, the barest disturbance of neurons in Stefan's receptive brain: What other practical things can you think of that Damon might have thought of? Things relating to a jailbreak? â€Å"Well†¦for a jailbreak? The first thing I can think of is for you to know your way around the city. I was brought here blindfolded but since they don't have the power to take the curse off vampires and make them human, I still had all my senses. I'd say it's a city about the size of New York and Los Angeles combined.† â€Å"Big city,† Elena noted, taking notes in her head. â€Å"But fortunately the only bits that would interest us are in the southwestern section. The city's supposed to be ruled by the Guardians – but they're from the Other Side and the demons and vampires here long ago realized that people were more afraid of them than the Guardians. It's set up now with about twelve to fifteen feudal castles or estates, and each of those estates has control of a considerable amount of land outside the city. They grow their own unique products and sell them in deals made here. For instance, it's the vampires who cultivate Clarion Loess Black Magic.† â€Å"I see,† said Elena, who had no idea what he was talking about, except the Black Magic wine. â€Å"But all we really need to know is how to get to the Shi no Shi – your prison.† â€Å"That's true. Well, the easiest way would be to find the kitsune sector. The Shi no Shi is a cluster of buildings, with the largest one – the one without a top, although it's curved, and you may not be able to tell from the ground – â€Å" â€Å"The one that looks like a coliseum?† Elena interrupted eagerly. â€Å"I get a sort of bird's-eye view of the city whenever I come here.† â€Å"Well, the thing that looks like a coliseum is a coliseum.† Stefan smiled. He really smiled; he's feeling well enough to smile, now, Elena rejoiced, but silently. â€Å"So to get you in and out, we just head from below the coliseum to the gate back to our world,† Elena said. â€Å"But to get you free there are – some things we need to collect – and those are probably going to be in different parts of the city.† She tried to remember if she had ever described the twin fox key to Stefan or not. It was probably better not to do it if she hadn't already done it. â€Å"Then I'd hire a native guide,† Stefan said immediately. â€Å"I don't really know anything about the city, except what the guards tell me – and I'm not sure if I would trust them. But the little people – the ordinary ones – will probably know the things you want to know.† â€Å"That's a good idea,† Elena said. She drew invisible designs with a transparent finger on his chest. â€Å"I think Damon really plans to do everything he can to help us.† â€Å"I honor him for coming,† Stefan said, as if he were thinking things out. â€Å"He's keeping his promise, isn't he?† Elena nodded. Deep, deep in her consciousness floated the thoughts: His word to me that he would take care of you. His word to you that he would take care of me. Damon always keeps his word. â€Å"Stefan,† she said, again in the innermost recesses of his mind, where she could share information – she hoped – in secret, â€Å"you should have seen him, really. When I did Wings of Redemption and every bad thing that had hardened him or made him cruel came undone. And when I did Wings of Purification and all the stone covering his soul came away in chunks†¦. I don't think you could imagine how he was. He was so perfect – and so new. And later when he cried†¦Ã¢â‚¬  Elena could feel inside Stefan three layers of emotion succeed one another almost instantaneously. Disbelief that Damon could cry, despite all that Elena had been telling him. Then, belief and astonishment as he absorbed her pictures and her memories. And finally, the need to console her as she stared at a Damon forever trapped in penitence. A Damon that would never exist again. â€Å"He saved you,† whispered Elena, â€Å"but he wouldn't save himself. He wouldn't even bargain with Shinichi and Misao. He just let them take all his memories of that time.† â€Å"Maybe it hurt too much.† â€Å"Yes,† said Elena, deliberately lowering her barriers so that Stefan could feel the hurt that the new and perfect creature she'd created had felt upon learning that he had committed acts of cruelty and treachery that – well, that would make the strongest soul flinch. â€Å"Stefan? I think he must feel very lonely.† â€Å"Yes, angel. I think you're right.† This time Elena thought a good deal longer before venturing, â€Å"Stefan? I'm not sure he understands what it's like to be loved.† And while he thought out his response, she was on tenterhooks. Then he said very softly, very slowly again, â€Å"Yes, angel. I think you're right.† Oh, she did love him. He always understood. And he was always most brave and gallant and trusting just when she needed him to be. â€Å"Stefan? Can I stay again tonight?† â€Å"Is it nighttime, lovely love? You can stay – unless They come to take me somewhere.† All at once Stefan was very solemn, holding her gaze. â€Å"But if They come – you'll promise me to leave then, won't you?† Elena looked straight into his green eyes and said, â€Å"If that's what you want, I'll promise.† â€Å"Elena? Do you†¦do you keep your promises or not?† Suddenly, he sounded very sleepy, but the right kind of sleepy, not worn out, but someone who has been refreshed and is being lulled into a perfect slumber. â€Å"I keep them close to me,† Elena whispered. But I keep you closer, she thought. If someone came to hurt him, they would find out what a bodiless opponent could do. For instance, what if she just reached inside their bodies and managed to make contact for an instant? Long enough to squeeze a heart between her pretty white fingers? That would be something. â€Å"I love you, Elena. I'm so glad†¦we kissed†¦Ã¢â‚¬  â€Å"It's not the last time! You'll see! I swear it!† She dropped new healing tears down on him. Stefan just smiled gently. And then he was asleep. In the morning Elena woke up in her grand bedroom in Lady Ulma's house, alone. But she had another memory, like a pressed rose, to put away in its own special place inside her. And somewhere, deep in her heart, she knew that these memories might be all she had of Stefan someday. She could imagine that these sweet-scented, fragile mementoes would be something to hold on to and cherish – if Stefan never came home.

Health Care Reform and Incentive for Physician Practice

Health Care Reform and Incentive for Physician Practice In recent years the integration of insurance companies and health service delivery organizations has led to radical change in the health care market. The attempt by these organizations to lower costs of health care by redistributing risk throughout the demand of the market has led to considerable changes for the suppliers in this markets, the physicians. To understand the dynamics of this affect on physicians, we must, first, understand the specifics of exactly what types of reform have taken place. The emergence of Health Maintenance Organizations, HMOs, has led to a major part of the reform in the health care market. These organizations serve to provide patients(health care consumers) with health care insurance and the service of medical care. In these types of organizations physicians are considered employees of the HMO, and are paid by a borne plan. This is to say that for each patient cared for, a physician receives a fixed quantity of money. This is dramatically different from the traditional fee-for-service (FFS) plan where physicians receive payment based on the amount and difficulty of work performed on a given patient(Folland, 93.). From these statements about managed care and traditional health care, we can see the bodywork for a disincentive for a physician to supply labor under an HMO type situation. Thro! ugh an expectation of a salary decrease, a quota to treat more patients in the same amount of time used in traditional care, and an increased possibility of legal suits correlated to the way in which health care is administered in a managed care model, we can see a major disincentive for upcoming physicians to work. The changing of a price model in modern health care has considerably lowered expected earnings of practicing physicians. Those physicians that participate in HMOs receive a flat rate on each patient treated. This is to ...

Four simple tricks for new years resolutions that stick

Four simple tricks for new years resolutions that stick Four simple tricks for resolutions that stick Its that time again. A new year, a (seemingly) new beginning and a brand new chance to do everything a bit better. Clean slates are always appealing, and the turning of one year into another is as good a prompt as any to make a change – especially since it comes preloaded with tradition. Yet, as we all know, those early pledges to eat better, exercise more or spend less so often slip by mid-January, or even sooner. And the same is true at work. You may have aspirations to climb the career ladder, learn new skills, improve your communication, win more bids or achieve higher levels of customer satisfaction. So, how can you ensure that your work-related good intentions become a catalyst for real and lasting change, to make your business objectives for 2017 a reality? 1. You need to actually want it It sounds ridiculously obvious, but its so important. We often pick resolutions because we think we should behave a different way, or they may even be based on what someone else wants from us. But internal motivation tends to trump external: if your heart isnt really in achieving a goal, youre unlikely to succeed. 2. You need to be SMART Every project managers favourite mnemonic for goal setting is a great fit here too. So make your resolutions specific, measurable, achievable, relevant and time-bound. Many resolutions fail because theyre too big and too vague: be more productive is a fine aim, but what does that actually look like in your daily life? Break down lofty ambitions into small, specific actions youll take, including when, where and how youll do each – and how youll track it. Introduce one and build up: willpower is a limited resource, so dont spend it all at once. 3. You need to harness the power of habit Were all walking bundles of habits, amassed over a lifetime. Good or bad, they have become so ingrained theyre automatic. Like our willpower, our daily ability to make decisions is limited, and your mind will seek ways to cut down the number it must make. Once something is habitual, doing it no longer requires a decision – hence the power habit has over us. You can harness this tendency in a positive way with something New York University professor Peter Gollwitzer terms if-then planning. This just means lodging in your head a cue (the if) for the new behaviour you want to establish (the then). For example, if you have a report deadline on Friday, then thats your cue to start the structure of your report on Monday at 9.30am. Your mind will look for the prompt, and has to make only a little effort when it arrives, as the decisions been made. 4. You have to just do it Have you ever said to yourself something like, ‘I don’t have time to learn new skills with my current workload’? Or perhaps you’ve put off starting that online course because trying to get a grip on something you can’t do yet can feel pretty uncomfortable in the early stages. (I know I have.) One of the key killers of new year’s resolutions – or any decision to change – is procrastination. Its built in to the practice: we generally commit ourselves to these new ways when the actual moment of action is safely in the distance. At that point, it feels good. Were pleased with our pledge, and the fact that we dont have to act on it yet. When were faced with following through, that high is often long gone. So just expect that. And vow that even if it feels less than pleasant, then youll do it anyway. Once youve done it just a few times, youre already on the way to forming a new pattern. You might even like it. And if you still cant shake the Ill-just-start-it-tomorrow habit, try to take an objective look at why youre procrastinating. For instance, if its starting a report that youre putting off, whats behind that? Perhaps its fear of it not being perfect. (Heres a gentle insider tip: it wont be. But thats OK.) Or maybe its because you dont yet have all the information you need. In that case, make finding that information your first task, rather than actually writing anything. Of course, thats another example of breaking down overwhelming and broad tasks into small, manageable sub-tasks. Happy new career Back to the new you of 2017 then. If you have a career-related resolution like winning a promotion, making more of an impact with your business writing, or just not putting work off to the last minute, remember to break it down into smaller, specific steps.

Opening Exercise Essay Example | Topics and Well Written Essays - 750 words

Opening Exercise - Essay Example The guesser will have to think creatively to pinpoint the word and concepts written on the paper. If a certain concept or word is unclear, team members can either research for clarification or better yet, ask the teacher to help explain and clarify the word or concept. Still, the participants are learning. The restrategizing aspect of the game will teach the players about their lapse in their communication techniques and from their mistakes apply remedial measures to improve performance just like in an organization. They could also learn from the other team. Each teams will also learn how to communicate properly so that they could guess the word and concept given the limited feedback of â€Å"YES, NO or COULD BE†. This would make the players appreciate how susceptible people are to miscommunication. The process will also teach the students the value of clear communication in an organization realizing the difficulty of guessing concepts and ideas when handicapped by less than ideal situations such as having noise in communication, not having all the information needed, and not clearly transmitted thoughts. The game can be applied to any subject. Only the words can be changed to suit the need of a particular subject. The game can also be made more challenging by letting the opposing team write the words that their opponents will have to guess. Of course they would naturally make the concept more difficult for other team to guess pushing the learning process to extend to more complicated concepts that would entice the students to study more to win the game without them realizing that they are already studying the
