Evidence-based Practice - Assignment Example This research will begin with the statement that PICOT refers to a formula that is designed to answer focused clinical questions concerning a given target population or a fundamental issue for nursing research. PICOT was developed to enhance the efforts of establishing an evidence-based practice in nursing. PICOT calls for continued research to improve the body of knowledge and base the current nursing practice on sound scientific research. PICOT will help to maintain the status of nursing as a professional and autonomous career. PICOT is an acronym that is used by clinicians when carrying out clinical research. This method of evidence-based clinical research promotes understanding among the researchers. The letter â€Å"p† stands for the study population. The letter â€Å"I† refers to the clinical intervention and its variables. The letter â€Å"C† is the comparison with a placebo while â€Å"O† refers to the outcome of the process after a particular inte rvention. The letter â€Å"T† refers to the time taken for an outcome of a nursing intervention can achieve an objective. In a patient with an abscess that has been recurring for six months, does prophylactic antibiotic treatment, compared to no treatment, reduce the rate of recurrence? The PICO (T) elements are; P = Patients with recurrent abscess I = Prophylactic antibiotic treatment C = No antibiotic treatment O = Decline in the high rate of recurrence of the abscess T = Six months

Financial Crisis and Their Possible Solutions Essay

Financial Crisis and Their Possible Solutions - Essay Example It is evidently clear from the discussion that financial crisis affected most parts of the world. It began in the US after the Difficulties in the US submarine market that had rapidly rocketed and spilled all over the world. Bordo et al find that the frequency of the financial crisis is higher than the previous one and can be comparable only to the Great Depression. It had detrimental impacts on different sectors of the economy in all countries. Reinhart, Reinhart and Rogoff have, in the past years documented the effects of the banking crisis that are typically proceeding by credit booms and asset price bubbles. They note that on average 35% real drop in housing prices stretch over a to almost six years. Equity prices fall over 55% over a period of 3 years, while output in those countries fall by 9% in two years, unemployment increases by 7% in four years while an 86% debt increase based on the pre-crisis level. Many models have documented the effects of the financial crisis. Adrian and Shin, Brunnermeier have documented a thorough review of the events preceding the financial crisis in late 2007 and early 2008. They note that the seeds of financial crisis can be traced back to the low interest rates policies adopted by the Federal Reserve and other world central banks after the collapse of the technology stock bubbles. The need for the debt securities by Asian banking institutions aided in fuelling the economic crisis. Acting as financial intermediaries, banks channel funds to potential investors. Through the process of borrowing and lending, they benefit from a diversified portfolio of risk sharing. They also act as monitors (Diamond, 1984) and streamline loans to well-organized customers (Gorton and Kahn, 1994) and other vital roles in maturity transformations. This implies that in crisis, every banking institution becomes concerned. For instance, Dell Aricia and Rajan (2008) provide that banks’ grief contributes to a decline in credit and low GDP .Fur ther evidence provides that those sectors, which heavily depend on external financing, perform relatively dismal during the banking crises. These effects are stronger and severe in developing countries. In addition, the report note that over the last two decades, banking sector continues to be complex in its modes of operations. For instance, banks use various instruments to hedge risks. However, despite the complexity banks have remained sensitive to the panics and runs. Gorton (2008) note that holders of short-term liabilities feared to fund banks as they the anticipated losses in the sector could have in their securities. The recent research proposes two theories to give a tentative explanation on the causes of the bank panics and runs. One argues that panics are undesirable events caused by random withdrawals unrelated to the changes in the real economy. Bryant (1980) and Diamond and Dybig (1983) note that agents have uncertain needs that relates to consumption. If other deposit ors believe and can even further establish the slightest of evidence, then all the agents will find it rational and imperative to redeem their claims from banking institutions and will cause the panics and banks’ runs. Another theory explains that banking crises are natural outgrowth of the business cycle. An economic slump will reduce the value of the bank resources, heightening the possibility that banks are unable to meet

As your faithful student I thank all of you. Executive summary. Table of content. Introduction Task 1 Explain what is data model, Evaluate different data models explain why older data models are being replaced by new data models. What is a Data Model? Data model is a collection of concepts that can be used to describe the structure of a database And also we can define it as When constructing any database it is compulsory to have the design of the database which provides a better mechanism for accessing the data in the database. The data model provides this facility and allows the DBA (Data Base Administrator) or the users to get the required information irrespective to the internal implementation of how the data is physically stored in the database. It can be broadly distinguished into 3 main categories: High-level or conceptual data models Low level or physical data models performance or execution of model There are so many data models use with data bases. As examples: Hierarchical data modal. Network data modal. Relational data modal. Object relational data model. Object oriented data model. Hierarchical data modal. Organizers of hierarchical data in a data modal hierarchical tree structure, there is a segment of parent and child data. This structure implies that a record may be repetition of information, generally in a data segment child. The serial data records, which have a set of join him sensation values. Collect all records intense specific offer together it in record type. These record types are the same of the table in the relational data model, and individual records that are the similar of rows. To make links between these records users type the modal hierarchical parent-child relationship. This is a one-to-many mapping between the types of records. Here is a diagram for hierarchical data model. Figure Network data modal. Network data model is looks like one of developed type of hierarchical data model. Because this also have parent and child connection. And also it is developed than hierarchical data model. Also network data model using many to much relationship in data .network data model is also greater than hierarchical data model. Also network data model is like a set. The network data model details of members or specification have categorizes as set. That set can be called as record. Network data model can have one or more records types. And also these have one to many relationships. Beside that it is permitted for use one to one relationship. When we consider about the diagram given below we can understand about the network data model. Figure Relational data modal. Relational data model is one of another data model. All data and relations are organized in a table. Also there are so many different rules for table. A table is a collection of records and each record in a table contains the same fields. Values Are Atomic. The Sequence of Columns is Insignificant. Each Row is Unique. Column Values Are of the Same Kind. Each Column Has a Unique Name. The Sequence of Rows is Insignificant. The relational data model is more complex than hierarchical and network data models. Also it covers large area by gathering data in to a table. There is a relation between each other records. Here is a relational data model diagram is given below. The all records are connecting with Sales facts table. Now we can see there have some connection of other record directly or indirectly to sales facts table. Figure Object relational data model. This model is another complex and more successful one of than above data models. Also object relational data model add latest object storage abilities to the relational systems at the core of modern information systems. So it is very useful for modern information systems. Because this object relational data model currently included various binary media like as music, video, pictures. â‚ ¬Ã‚  Object relational database management systems server can implement complexes analytical and data processing operations to search and turn things complex and other multimedia.â‚ ¬Ã‚  Ã¢â€š ¬Ã‚  Designers can work with database structures familiar spreadsheets and definition language, while absorbing new possibilities to manage the object easily and with more performance. Here is the example for object relational data models. Figure (http://www.joe-stevens.com) Object oriented data model. This model developed by using C++, Java and smart talk object oriented programs. â‚ ¬Ã‚  A major benefit of this approach is to unite the application and development of the database to the data model smooth and linguistic environment. Because of that there are more results as like as Applications call for less code, use the more natural data modeling, and code bases easier to maintain. Because of this benefits object developers can easily write data bases with modest application without effort.â‚ ¬Ã‚  Ã¢â€š ¬Ã‚  Unlike an RDBMS a complex structure where data must be flattened to fit into tables or joined together from these tables to form the structure in memory, object oriented DBMS have no performance degradation to store or retrieve a web or a hierarchy of interrelated objects.â‚ ¬Ã‚  Ã¢â€š ¬Ã‚  This mapping one-to-one of the objects of the programming language objects to database objects has two advantages over storage approaches: it provides higher performance managemen t of objects, and allows better management of complex relationships between objects. â‚ ¬Ã‚  This makes the most suitable object DBMS to support applications such as financial systems portfolio risk analysis, applications of telecommunications services, world wide web document structures, design and manufacturing systems and patient record systems of hospital, which have complex relationships between data.

Humans and Tails :: Anatomy Persuasive Argumentative Essays

Humans and Tails When studying the anatomy of humans in biology textbooks, many authors marvel over the complexity of the human body. Attributes such as our opposable thumbs, bipedal mobility, and cognitive abilities are extolled; however, humans are at a serious disadvantage. We lack major appendages that would aid in daily living; they could greatly improve quality of life. One such appendage is a tail; understandably, some humans have grown accustomed to their current mode of living and would shy away from any change despite its advantages. For this reason, the tail that I am about to depict is prosthetic, allowing for attachment and removal when desired. A tail would give a human numerous advantages, as long as it is constructed in such a way to allow for several functions. With the proper appendage on the distal end, it could perform as a third arm, a temporary seat, or simply an aesthetic addition. All of these functions will be explained in further detail later. In order to create a tail that is as dexterous as possible, it may be useful to study the tails of several different animals and reptiles to determine what the best structure would be. Many primates have prehensile, or grasping, tails. These are comprised of articulated linkages; they cannot rotate in all directions, preventing potential flexibility. Flexor and extensor muscles act as both the driving â€Å"motor† of the tail, and attached bones serve as a support system. Another tail type is similar to an elephant’s trunk; no bone is involved in the structure. Movement is achieved through muscle contraction, and a sheath that is similar to the composition of a tendon prevents shrinkage in the overall â€Å"tail.† Sharks demonstrate a third tail type that is very unique in structure, allowing for exceptional movement. Muscles are arranged around the vertebrae in a conical formation and are attached by three-dimensional tendons. Contraction of these muscles creates a motion that is fluid, and the tail is capable of movement in all directions. In 1994, Kevin C. Zippel, a student zoologist at Cornell University made a surprising discovery. While studying in Papua New Guinea, specifically on the island of Bougainville, he found that a remarkable lizard known as the Solomon Island skink somehow evolved a very unique tail.

Professional School Counseling Essay

The 5 themes are character education, bullying, social-conflict, academics, and mental illness. Additionally, this paper will include important elements of school counselor identity, function and ethics. A section of the paper will give biblical values and insights related to the subject of professional school counseling. The experience of research has provided the reader with the personal reflections concerning school counseling and a discussion of the commitment to provide biblically grounded, ethical and empirically based services from the point of view of the writer. Introduction Children are in a society where the world is rapidly changing. Due to influx of social and economic changes and problems that are brewing within the homes of our students: these problems tend to spill over into the schools. The problems that are presented in the schools are escalating, when you think that things are improving. The purpose of this paper is to give some insight on the problems that professional school counselors faced in our schools. Every problematic area is not covered in this paper because it is so much research on many degrees of issues that professional counselors face. We propose that with the proper training, programs and support of the schools, counselors will be able to see a positive change. History and Development The factors leading to the development of guidance and counseling in the United States began in the 1890s with the social reform movement. Formal guidance programs using specialized textbooks did not start until the turn of the twentieth century. In 1958 the National Defense Education Act (NDEA) was enacted, providing aid to education in the United States at all levels, public and private. One of the consequences was the compulsory education movement and shortly thereafter the vocational guidance movement, which, in its early days, was concerned with guiding people into the workforce to become productive members of society. The social and political reformer Frank Parsons is often credited with being the father of the vocational guidance movement. His work with the Civic Service House led to the development of the Boston Vocation Bureau (Sandhu, 2000). Guidance and counseling in these early years were considered to be mostly vocational in nature, but as the profession advanced other personal concerns became part of the school counselor’s agenda. Introduction of Topic Professional school counselors are certified and licensed educators with a minimum of a master’s degree in school counseling that make them uniquely qualified to address all students’ academic, personal/social and career development needs by designing, implementing, evaluating and enhancing a comprehensive school counseling program that promote and enhance student success (Sandhu, 2000). Professional school counselors are employed in elementary, middle/junior high and high schools; in district supervisory positions; and counselor education positions. Professional school counselors uphold the ethical and professional standards of ASCA and other applicable professional counseling associations, and promote the development of the school counseling program based on the following areas of the ASCA National Model: Foundation, delivery, management and accountability.
