Definition and Examples of Short Answers in English

Definition and Examples of Short Answers in English In spoken English and informal writing, a short answer is a response made up of a subject and an auxiliary verb or modal. A short answer is generally regarded as more polite than just an abrupt yes or no. Conventionally, the verb in a short answer is in the same tense as the verb in the question. Also, the verb in the short answer should agree in person and number with its subject. Examples and Observations How did she do in her exams? Maria had already told me she had done quite well, but I was now flailing around to keep the conversation going.She passed.She is all right, isnt she?Yes, she is, he replied firmly.(Vikram Seth, An Equal Music. Random House, 1999)The poor lass took quite a fall, didnt she? Gelfrid remarked. Is she usually so clumsy?No, she isnt,† Judith answered.(Julie Garwood, The Secret. Pocket Books, 1992)Youre asking yourself, Can I give this child the best possible upbringing and keep her out of harms way her whole life long? The answer is no, you cant.(Barbara Kingsolver, The Bean Trees. Harper Row, 1988)Can we change? Yes, we can. Can they change? Yes, they can.(Oz Clarke, Oz Clarkes Pocket Wine Guide. Sterling, 2009)Will, youve been in love before, havent you? I mean, with Anna, of course . . . and your various . . . well, you have, havent you?Will looked into his glass. No. No, I havent.(Jennifer Donnelly, The Tea Rose. Macmillan, 2004) Whats up with him?His stomach is sick. Hes nervous about his speech.Hes got food poisoning! Helen declared. â€Å"Hasnt he?†Ã¢â‚¬Å"No, he has not!†Ã¢â‚¬Å"Yes, he has.†Ã¢â‚¬Å"No, he has not!†Ã¢â‚¬Å"Yes, he has.†(Marian Keyes, Anybody Out There? William Morrow, 2006)No, I wont, Jeremiahno I wontno I wont!I wont go, Ill stay here. Ill hear all I dont know, and say all I know. I will, at last, if I die for it. I will, I will, I will, I will!(Charles Dickens, Little Dorrit, 1857) Short-Answer Patterns Answers are often grammatically incomplete, because they do not need to repeat words that have just been said. A typical short answer pattern is subject auxiliary verb, together with whatever other words are really necessary. Can he swim? Yes, he can.(More natural than Yes, he can swim.)Has it stopped raining? No, it hasnt.Are you enjoying yourself? I certainly am.Youll be on holiday soon. Yes, I will.Dont forget to telephone. I wont.You didnt phone Debbie last night. No, but I did this morning. Non-auxiliary be and have are also used in short answers. Is she happy? I think she is.Have you a light? Yes, I have. We use do and did in answers to sentences that have neither an auxiliary verb nor non-auxiliary be or have. She likes cakes. She really does.That surprised you. It certainly did. Short answers can be followed by tags . . .. Nice day. Yes, it is, isnt it? Note that stressed, non-contracted forms are used in short answers.(Michael Swan, Practical English Usage. Oxford University Press, 1995) Short Answers With So, Neither, and Nor Sometimes a statement about one person also applies to another person. When this is the case, you can use a short answer with so for positive statements, and with neither or nor for negative statements using the same verb that was used in the statement. You use so, neither, or nor with an auiliary, modal, or the main verb be. The verb comes before the subject. You were different then. So were you.I dont normally drink at lunch. Neither do I.I cant do it. Nor can I. You can use not either instead of neither, in which case the verb comes after the subject. He doesnt understand. We dont either. You often use so in short answers after verbs such as think, hope, expect, imagine, and suppose, when you think that the answer to the question is yes. Youll be home at six? I hope so.So it was worth doing? I suppose so. You use Im afraid so when you are sorry that the answer is yes. Is it raining? Im afraid so. With suppose, think, imagine, or expect in short answers, you also form negatives with so. Will I see you again? I dont suppose so.Is Barry Knight a golfer? No, I dont think so. However, you say I hope not and Im afraid not. It isnt empty, is it? I hope not. (Collins COBUILD Active English Grammar. HarperCollins, 2003)

Byetree procurement strategy Essay Example | Topics and Well Written Essays - 5500 words

Byetree procurement strategy - Essay Example However, this changed and went beyond the old practices when the UK government became active in the promotion of sustainable development and combating climate change (AECOM, 2012). In addition, the highway customers/consumers have become discerning on the quality and quantity of MSA services. It is a great challenge for the Baytree Leisure Plc, which is the developer of a proposed MSA, to design and build the facilities in accordance with the existing Building and Environment Regulations of UK, and customers’ demands and expectations. Therefore, it is in this context that the Baytree Plc has determined the type of procurement method to be applied in order to mitigate the construction and engineering risks as well as to achieve total sustainability and environment-worthiness of the project. Key Procurement Issues for Baytree Leisure Plc Procurement process for Baytree in the development of Motorway Services Area (MSA) is covered by the UK standard with the goal for an efficient and streamlined approach. To meet and achieve satisfying result, the project will integrate all members/key people in the procurement chain which included the project owner, contractors, sub-contractors and the customers. A closer working experience between Baytree and its general contractor and specialty contractors may yield better results in consideration of the requirement of customers. Customers in this instance are the driving public not only in the area but also visitors. Their needs must be considered from the design process to the procurement in order to fully address time, cost, and quality constraints if any. These are described in detail on the next discussion. Key procurement issues for Baytree for the construction and development of MSA in consideration of the requirements include but not limited to the design of sustainable and environmentally sound MSA details, integration of this design to the various stages, identifying locally available materials suppliers as wel l as well as professionals and teamworkers, and identifying alternative sustainable and environmentally sound supplies, materials and equipment, efficient delivery and storage.

Literature Review - Transformational Leadership Essay

Literature Review - Transformational Leadership - Essay Example In his discussion on political leaders, Burns defined transformational leadership as a process wherein leaders and followers mutually â€Å"promote each other to higher levels of morality and motivation (Jandaghi Matin & Farjami, 2009, p. 211). Another definition identifying transformational leadership as a process is that of Bass (1998) who described transformational leadership not as a characteristic but as a process wherein one person creates a link with another person, thereby establishing a connection that helps increase the level of motivation and morality, both for the leader and for the follower. Two elements appear common to these definitions, that of citing morality as the motivation for behavior, and the strong personal relationship between leader and follower, or between persons, as the source of that motivation. According to Barker (2001), leadership is: (1) a process not specifically a function of the person in charge, but a function of individual wills and needs addre ssed by the dynamics of the collective will; (2) a process of adaptation and of evolution, a deviation from convention involving the dynamic exchange and interchange of value; and (3) a process of energy, not structure. Leadership and change therefore go hand in hand; they are the two most important, yet most problematic elements of organizational behavior (Burnes & By, 2011). Leadership is concerned with bringing about transformational change. The fundamental differences between managers and leaders: †¢ Managers can be dismissed from their jobs for breaking rules; leaders can be dismissed for not breaking the rules when it is called for. †¢ Performance measures against which managers are evaluated are clear and short-term; criteria for judging leaders are more vague and long-term. Transformational v transactional leadership The study by Jiao, Richards and Zhang (2011) observed that transformational leaders and transactional leaders are often viewed in juxtaposition and th erefore contrasted against each other. However, there are successful leaders whose style and approach applies both transactional and transformational leadership principles. Transactional leadership is described as a process whereby followers perform assigned tasks in accordance with the leader’s instructions in contemplation of rewards and praise, while leaders ensure that the promised remuneration or praise, together with the resources necessary to complete the task, are given as promised. The deal becomes a quid-pro-quo, a give-and-take with each party working towards their own self-interest. Transformational leadership, however, involves profound change, wherein the leaders raise their followers’ awareness of the value and importance of specified outcomes, and suggest ways by which the follower may attain these outcomes. Leaders influence their followers and motivate them with a moral purpose, so that they transcend their personal interests and work for the collecti ve benefit, in the process fulfilling a higher order need. When the two (i.e., transactional and

Helicopter investigation Essay Example for Free

Helicopter investigation Essay Easily established, the sycamore tree produces sycamore seeds. These seeds are of an extremely strange looking seed, I say this because the seeds when in the air they spin like tiny helicopters. Due to the spinning they are kept in the air for a longer amount of time. Aim In this investigation I have been asked to find out how long it takes for a paper helicopter to fall 2 metres. After doing this I shall investigate other ways of changing the timing of its landing. I shall do this by using a range of variables. These include of:   Length of wings Number of tailsI have chosen to use the variable of the number of paperclips being added to the tail of the paper helicopter that I shall make. I have chosen to change this variable because I know that gravitation is the effect of the gravitational force of attraction, which acts between all objects in the universe. For example it is widely noticed with massive objects like the planets. The planets remain in orbit because of gravitational force of attraction. The gravitational force, which pulls the object downwards, is called the weight of the object. Isaac Newton stated that there is a gravitational force of attraction between any two objects with mass, which depends on their masses, and the distance between them. I think with this information I can easily say that by adding more and more paperclips on to the tail of the paper helicopter it will gain more weight which will cause the gravitational force to pull it downwards rather than upwards as there is a bigger mass pulling it downwards. I also chose to use this variable instead of changing the length of the wings because I thought that it would have a much more affective difference in the timing of its landing. In this investigation in order to get the best results possible I shall be doing the experiment 5 times. This will give me a good range of results and a better result as I get a better view of the timing of how long it takes to land with different numbers of paperclips attached to the tail of the paper helicopter. It is always essential to make every investigation of whatever type it is to make sure that it is going to be a fair test. In order to achieve this I shall only be changing one variable, which I have already established to be of the number of paperclips added to the tail of the paper helicopter. Prediction In the investigation which I shall be doing I think that I will be expecting for the paper helicopter to fall to the ground in a much quicker timing when it has 5 paperclips attached to the tail of it, than it should do when it has either none, 1,2,3,or 4 paperclips attached to the tail of the paper helicopter. I say this because from the information that I have already been supported by to take this investigation further, it also helps me with my prediction. Using Isaac Newtons law of gravitation, I can easily say that with his theory of objects being pulled downwards by a force called weight, it helps me to explain that when I add more and more paperclips to the tail of the paper helicopter it doesnt just mean that the number of paperclips are increasing but it also means that the mass is also increasing. Causing the paper helicopter to fall downwards and not upwards. Why do I say this? I say this because an example being is Say if I were to get a balloon and fill it with Helium, due to the helium being placed inside of the balloon we already know that for some reason the balloon seems to go up into the air. This is because Helium is lighter than air causing the gravitational force to pull it upwards and not downwards as the weight is very low. Whereas if we were to place water inside of the helium filled balloon it would be brought back downwards because the weight of the water forces the balloon to be brought back down again. What do I expect in the graph outcome? It is easily said that when a line graph is drawn out to show the results of the investigation that I am about to carry out, the line should start off near the very top of the y axis. This should be when there are no paperclips attached to the tail of the paper helicopter. Near quite the very end of the x axis should the very last point be drawn, therefore making the plotted points decreasing as it goes along the x and y axis. I think that this graph prediction would go for both the average graph and the graphs for all 5 sets of results, which shall be already obtained by that time. Equipment (As shown in Diagram 1. 1) Paper   Paper clips   Stopwatch/Timer   Scissors   Ruler Diagram 1. 1 Method What should I be doing in order to make this investigation to the highest standard possible? In order to get good results I firstly have to start off by making the paper helicopter. In this experiment I have to look into the needs of safety, I have noticed that none would have to be carried out such as goggles or safety cloaks etc How do I make a paper helicopter? Firstly I am to get a piece of A4 paper. Some may choose for the A4 to be coloured but I will just leave it to be plain. In our class lesson Mr Findley (our physics teacher,) has given us an information sheet, which includes of the carcass drawing of the paper helicopter. It shows us where to cut and fold and what measurements are involved. Diagram 1. 2 The diagram, which has been drawn above, has not been drawn to scale. Once I draw out the drawing of the paper helicopter on the A4 sheet of paper, carefully done using a ruler of course. I am to cut along and fold along the lines as described: Where the dotted lines are shown this is where we are to fold along, and where the straight solid lines have been drawn in, we are to cut along them. The cutting of course will be done with a pair of scissors. After they are cut out and folded along, some may find it better and more presentable if they are to be decorate and colour in their paper helicopters! What else is involved in this investigation? Once all of the above has been done we are to set up our equipment out. Having set out the timer, paperclips, and paper helicopter in front of me, I am to make sure that I have drawn out a results table, which I will record the timings down in. (As shown in the results table. ) I will then ask for a little help for getting the timing at the best time possible. When I went to drop/release the paper helicopter from my hands I realised that I wasnt actually in fact dropping/releasing the paper helicopter from 2 metres of height. In fact I was dropping it from my height with my arms being placed right above my head as high as I could manage. So I then made sure to measure how high I was releasing the paper helicopter from, I found that with the heels of my shoe and my arms being stretched up way above my head I was actually releasing the paper helicopter from a height of 2 metres and 3 centimetres. I left the measurement of the height I was releasing the paper helicopter at how it was already, because it was getting to the point where it would be getting very time consuming. When dropping the paper helicopter out of my hands I am to make sure that I drop it at the same time that my friend is to say GO, this is so that he can time it with accuracy. When the paper helicopter will land on the ground I will then yell STOP, so that he is able to stop the timer/stopwatch at the right time in order to get the most accurate timing possible. When I get results for dropping the paper helicopter without any paperclips attached to the tail of it, 5 times, I will make sure that I have written down the timings in my results table. After doing so, I am to attach the first paperclip to the paper helicopter and then do the same thing again. (Drop the paper helicopter, time it, and write down timings in results table. ) After every 5 sets of results with the same number of paperclips attached, I am to add another paperclip to the paperclip, which is already placed on the tail of the paper helicopter. I shall do this until I have 5 paperclips attached to the tail of the paper helicopter. How the paper clips should be placed has been shown in the diagram below. Diagram 1. 3 Results Table Number Of Paperclips 1st (Time in Seconds) 2nd (Time in Seconds) 3rd (Time in Seconds) 4th (Time in Seconds) 5th (Time in Seconds) Average (Time in Seconds) 08 As you can see, in the results tables above I have gathered all my timings into the table. Once I had placed all my timings in the table I was to work out the average of each set of timings. To do this I was to add up all of the sets of timings together and then divide it by 5 because that was the number of times I had done the experiment for each set. Here are my workings out towards how I worked out the average for each set of results. Workings out for Average(s) (Please note that / stands for the division sign) When working out the, I firstly got all my timings for the specific set of results, added them together and divided them by 5, I divided it by 5 because this was the number of times I had timed it falling from the air to the ground. As shown below: Number of paperclips = 0 Timings 1Graphs/Conclusion I have formed out a graph to show the results of the five sets of results. Another graph is shown on the next page, except this is a graph, which shows the averages of all 5 sets of results, which I had gathered in my investigation. From looking at this graph we can easily say that the second set of results stand out the most. I have re-checked my results and have noticed that none of the outcome results really stand out greatly, as they are all in proportion. This shows me that my experiments had gone very well without making any large genuine mistakes. I think that the 2nd time I did all the results, the timing may not have been stopped at the right time or maybe not started at the right time, causing the timing to be of a much higher outcome than it should have done. There is not really much of a time difference from when there was two paperclips on the tail of the paper helicopter to when there was three paperclips attached to the paper helicopters tail. Looking back at the result table I can see that there is only a difference of 0. 06 seconds whereas in my other results I have found there to be at least a 0. 10 second difference. It is obviously noticeable that my prediction was to go ahead to be forwardly correct. I can say this with confidence because I had information to back up my prediction, which helped me forward, my ideas towards what should actually happen in my experiment. As said earlier in my prediction, I mentioned that the line would be decreasing down towards the x axis and away from the y axis. We can see in the graph above that this predicament was proved to be correct. From looking at this averages graph it is easily spoken of that the investigation that I have carried have has gone very well. I say this because as shown above, we can see that the average line is actually going downwards as the number of paperclips had increased on the tail of the paper helicopter. Thus showing that my prediction was right. I was able to make sure that my prediction was quite reliable with backing it up with a hypothesis, which had been concluded, from Isaac Newtons Law of Gravitation. With the information from this Law of Gravitation I was able to predict that when there is a force being put onto an object from its natural force then it is called weight as it is pulling it downwards. So when I was asked to do an experiment that was involved in placing more and more paperclips to the tail of a paper helicopter I already knew in my mind that the timing of the landing would get shorter and shorter. This was due to general knowledge but also scientific knowledge Isaac Newtons Law of Gravitation. With this scientific explanation we have been able to predict many scientific happenings. Evaluation I am glad to say that throughout the whole of this investigation I did not make any noticeable, genuine mistakes. I later went on to find out that I was standing at a height of 2 metres and 3 centimetres. This information of course was later found out after I was more than half way through the experiment, so I had to decide whether to go ahead with doing the experiment all at a drop of 2 metres and 3 centimetres or change it and have half the results at 2 metres and 3 centimetres whilst the rest of the results would be obtained from a height of an exact 2 metres. I had decided that if I were to go on to do this I would not be carrying out a fair test. Although the investigation was asked of a 2 metre drop I still thought that although I had dropped it at an extra 3 centimetres higher it was still a very fair test because I had kept drop height throughout the whole of the investigation. Whilst doing the investigation I had managed to do everything according to how I had written it out to have been done, although sometimes I had to be re-timed as mistakes were made as I sometimes dropped the paper helicopter without being told to! All in all I think the investigation was carried out well and was a fair test, I made sure that only one variable was changed and that the timing was done at the most accurate timing possible. In order to make it a fair test it also meant that safety was to be involved as well, as far as I was concerned not many safety measures had to be taken, I say this because as mentioned earlier no safety goggles were needed, no hair was really in need of being tied back and no safety cloaks were to be worn. The only safety we were to be notified was to tuck in our stools so that no accidents were to be caused as the investigations were being held. Looking back at my results I dont really think that there were really any results which were unexpected, there may have been the one or two timings which may have been timed a bit earlier than they should have been but nothing which was really way out of proportion. If I were to do this experiment again I think that I will definitely make sure that I am to drop the paper helicopter at a height of 2 metres and not 2 metres and 3 centimetres! I shall aim to achieve more results although I feel that I already have a reasonable amount of timings. I think that if I were to do the experiment again I would achieve a very similar set of results, as it would only be from the difference of 3 centimetres.

The Reform Of Schools :: essays research papers

The Reform of Schools   Ã‚  Ã‚  Ã‚  Ã‚  The government of Ontario proposes there is a need to make universally accepted rules in the school system. For students to be more disciplined, the government needs to achieve new province wide standards. If the new school standards will not discipline the students, and if each school entails its guidelines, then the government's province wide code of conduct will fail. Moreover, the intervention of the government will not enforce the students to become more disciplined. While the arguments for producing new rules are unrealistic, more powerful arguments can be made supporting the current code of conduct.   Ã‚  Ã‚  Ã‚  Ã‚  With the government's proposition to create a new code of conduct, the students will receive more disciplinary action. Just as the law governs society, the province wide guideline governs the student body. Since the rules will be explained, and since the students will understand the consequences of their actions, then the students will follow these rules. Due to the thoroughness and strictness of the outcomes, there will be fewer problems in the school system. Moreover, to separate schools means to separate students. Since the new code of conduct produces equality, and since it sets forth equal status among individuals, then the students will have a standard that the entire province takes part in. Now, the schools are going from each one entailing their code of conduct. To treating all schools as equals. For example, if a student in Ontario skips out of class, and if the student receives a punishment (making up that class on their time  ® weekends), then the students in other provinces will not skip out of class. Overall, the new bill will make the students who do not want to be at school the school's choice, not the students.   Ã‚  Ã‚  Ã‚  Ã‚  In opposing this proposition, the intervention of the government will not solve schools individual problems. Since discipline is taking place in schools, and since certain schools acquire more disciplinary action from others, then the current code of conduct exemplifies self-discipline and respect towards authority. Purpose for multiple codes of conduct allows the school system to punish the students accordingly. If there was a new province wide standard, there would be one punishment to distribute; however, with the current system, teachers are allowed to fluctuate the punishment according to the severity of the crime. In addition, punishments and discipline play an active role in a student's development. It is essential in determining respect for themselves and authority.

Nursing and Theory

Theories and models of nursing practice Dr. Sabah Abbas Ahmad College of Nursing university of Baghdad Sabah. [email  protected] com COMPETENCIES 1. Definitions of theory, concept, model, proposition. 2. Explain the relationships of concepts and propositions to theory 3. Discuss the purpose of theory. 4. Explain the USE OF theories from other disciplines: . .5. Explain the interdependent roles of nursing practice, nursing theory, and nursing research. .6. History and evolution of nursing theory 7. Identify m Common concept in nursing Theories. 8.Identify the three categories relating to the scope of theories. .. – Theories and models of nursing practice Introduction: Nursing theory provides a perspective from which to define the what of nursing, to describe the who of nursing (who is the client) and when nursing is needed, and to identify the boundaries and goals of nursing’s therapeutic activities. Theory is fundamental to effective nursing practice and research. Th e professionalization of nursing has been and is being brought about through the development and use of nursing theory.The basic elements that structure a nursing theory are concepts and propositions. In a theory, propositions represent how concepts affect each other. A concept is the basic building block of a theory. Definitions – A concept : Is a vehicle of thought? According to Chinn and Kramer (1995, p. 78), the refers to a â€Å"complex mental formulation of †¦ our Perceptions of an observable fact that term concept the world. † A concept labels or names a phenomenon, can be perceived through the senses and explained.A concept assists us in formulating a mental image about an object or situation. Concepts help us to name things and occurrences in the world around us and assist us in communicating with each other about the world. Independence, self-care, and caring are just a few examples of concepts frequently encountered in health care. Theories are formulat ed by linking concepts together. -A conceptual framework or Model: is a structure that links global concepts together and represents the unified whole of a larger reality.The specifics about phenomena within the global whole are better explained by theory. By its nature, a concept is a socially constructed label that may represent more than a single phenomenon. For example, when you hear the word chair, a mental image that probably comes to mind is an item of furniture used for sitting. The word chair could represent many different kinds of furniture for sitting, such as a desk chair, a high chair, or an easy chair . It is important to remember that the same concept may be used differently in various theories.For example, one nursing theory may use the concept of environment to mean all that surrounds a human being (the external environment), whereas another theory may use this concept to mean the external environment and all the biological and psychological components of the person (the internal environment). – What Is a Proposition? A proposition: (another structural element of a theory) is a statement that proposes a relationship between concepts. An example of a nonnursing proposition might be the statement â€Å"people seem to be happier in the springtime. This proposition establishes a relationship between the concept of happiness and the time of the year. A nursing propositional statement linking the concept of helplessness and the concept of loss might be stated as â€Å"multiple and rapid losses predispose one to feelings of helplessness. † Propositional statements in a theory represent the theorist’s particular view of which concepts fit together and, in most theories, establish how concepts affect one another. What Is a Theory? A theory: is a set of concepts and propositions that provide an orderly way to view phenomena.In the scientific literature, Nursing theory is developed to describe the phenomenon (process, occurrence, or event) called nursing. Nursing theory differentiates nursing from other disciplines and activities that in that the purposes of describing, explaining, predicting, and controlling desired outcome of nursing care practices. – â€Å"The purpose of a theory: in scientific disciplines is to guide research to enhance the science by supporting existing knowledge or generating new knowledge†. A theory not only helps us to organize our thoughts and ideas, but it may also help direct us in what to do and when and how to do it.The use of the term theory is not restricted to the scientific world, however. It is often used in daily life and conversation. For example, when telling a friend about a mystery novel you are reading, you may have said, â€Å"I have a theory about who committed the crime. † -USE OF theories from other disciplines: In addition to using theories specifically constructed to describe, explain, and predict the phenomena of concern to nursing, the nursi ng profession has long used theories from other disciplines. A discipline : is a field of study.Theories from biological, physical, and behavioral sciences are commonly used in the practice of nursing. For example, nonnursing theories such as Maslow’s Hierarchy of Basic Human Needs, Erikson’s Theory of Human Development, and Selye’s General Adaptation Syndrome have been and continue to be useful in nursing practice. These nonnursing theories are often incorporated into nursing practice together with specific nursing theories. – – Importance of nursing theories ;in clinical practice: Nursing theories provide a framework for thought in which to examine situations.As new situations are encountered, this framework provides a structure for organization, analysis, and decision making. In addition, nursing theories provide a structure for communicating with other nurses and with other members of the health care team. Nursing theories assist the discipline of nursing in clarifying beliefs, values, and goals, and they help to define the unique contribution of nursing in the care of clients. When the focus of nursing’s contribution is clear, then greater professional autonomy and, ultimately, control of certain aspects of practice are achieved.In the broadest sense, nursing theory is necessary for the continued development and evolution of the discipline of nursing. Because the world of health care changes virtually on a daily basis, nursing needs to continue to expand its knowledge base to proactively respond to changes in societal needs. Knowledge for nursing practice is developed through nursing research that, in turn, is used to either test existing theories or generate new theories. Nursing Practice Nursing research Nursing theory Process of knowledge development. Nursing practice, theory, and research are interdependent.Nursing theory development and nursing research activities are directed toward developing nursing practi ce standards . Nurses may use a specific nursing theory to help guide their practice or may choose a more eclectic approach and adopt ideas from several theories. Both of these approaches are valid. Furthermore, nurses may find some theories more appropriate for certain situations. In that case, one theory can be used with a client in a home health care setting, whereas another theory may be more applicable to a client in an acute care environment.Regardless of the approach chosen, nurses will recognize the value and usefulness of nursing theory as a tool for effective nursing practice. Common concept in nursing Theories: Four concepts common in nursing theory that influence and determine nursing practice are: 1-The person (patient) 3- Health and 4- Nursing Each of these concepts is usually defined and described by a nursing theorist, and although these concepts are common to all nursing theories, both the definition and the relations among them may differ from one theory to another .Of the four concepts, the most important is that of the person . The focus of nursing, regardless of definition or Theory, is the person. Relationship of theory to nursing process: Professional nurses use theories from nursing and from the behavioral sciences to collect, organize, and classify patient data and to understand, analyze, and interpret patients' health situations.Theoretical concepts and theories guide all phases of the nursing process, including planning, implementing, and evaluating nursing care, while also describing and explaining desired responses to and outcomes of care. The major concepts of a chosen model or theory guide each of the nursing process . The concepts serve as categories to the nurse in determining what information is relevant and should be collected to make assessments and to formulate nursing diagnoses.The concepts also suggest the appropriate types of nursing interventions and patient outcomes to be included in the care plan. Types of theories: â €Å"Although theories address relatively specific and concrete phenomena, they vary in scope. Scope refers to the relative level of substantive specificity of a theory and the concreteness of its concepts and propositions† three different categories relate to the scope of theories: grand theories, middle-range theories, and micro-range theories.This classification is applicable to both nursing and nonnursing theories. 1- A grand theory is composed of concepts representing global and extremely complex phenomena. It is the broadest in scope, represents the most abstract level of development, and addresses the broad phenomena of concern within the discipline. Typically, a grand theory is not intended to provide guidance for the formation of specific nursing interventions, but rather provides an overall framework for structuring broad, abstract ideas (Fawcett, 1993).An example of a grand theory is Orem’s Self-Care Deficit Theory of Nursing. 2- Middle-Range Theory : A theor y that addresses more concrete and more narrowly defined phenomena than a grand theory is known as a middle-range theory. Descriptions, explanations, and predictions put forth in a middle-range theory are intended to answer questions about nursing phenomena, yet they do not cover the full range of phenomena of concern to the discipline. A middle- ange theory provides a perspective from which to view complex situations and a direction for interventions (Fawcett, 1993). An example of a middlerange theory is Peplau’s Theory of Interpersonal Relations. 3- A micro-range theory is the most concrete and narrow in scope. A micro- range theory explains a specific phenomenon of concern to the discipline (Fawcett, 1993), such as the effect of social supports on grieving and would establish nursing care guidelines to address the problem. History and evolution of nursing theory The work of early nursing theorists in the 1950s focused on the tasks of nursing practice from a somewhat mechan istic viewpoint. Because of this emphasis, much of the art of nursing—the value of caring, the relationship aspects of nursing, and the esthetics of practice—was diminished. During the decades of the 1960s, 1970s, and 1980s, many nursing theorists struggled with making nursing practice, theory, and research fit into the then prevailing view of science.Reflecting changes in global awareness of health care needs, several contemporary nursing theorists have projected a new perspective for nursing that truly unifies the notion of nursing as both an art and a science. Noted nursing theorists such as Leininger, Watson, Rogers, Parse, and Newman have been urging the discipline of nursing to embrace this new emerging view that is seen as more holistic, humanistic, client focused, and grounded in the notion of caring as the core of nursing.Since the early 1950s, many nursing theories have been systematically developed to help describe, explain, and predict the phenomena of conc ern to nursing. Each of these established theories provides a unique perspective and each is distinct and separate from other nursing theories in its particular view of nursing phenomena.
