The Nature and Characteristics of Schizoid Essay Example for Free

The Nature and Characteristics of Schizoid Essay Abstract Eugen Bleuler first used the term â€Å"Schizoid† in 1908 and described it as â€Å"a human tendency to direct attention toward ones inner life and away from the external world†. Schizoid Personality Disorder (SPD) is characterized by a lack of interest in any form of social relationship, a solitary lifestyle, and secretness. People with SPD are often indifferent, which can cause interpersonal difficulty. Individuals with the disorder may have trouble voicing their opinions when faced with unfavorable situations, and most often remain passive about many issues. Communication with others can be awkward and lack sincere meaning. As a result, they are not able to accurately understand how others think of them, and know how well they are getting along with others. This can lead to a feeling of severe self-consciousness and paranoia. Schizoid Personality Disorder: The Nature of Schizoid Personality Disorder The American Psychiatric Association (2008) reports that the prevalence in the general population of schizoid personality disorder (SPD) in the general population is less than 2%. Other studies have found a community prevalence of 5.1% in the United States. There is an increased prevalence of schizoid personality disorder in relatives of people with schizophrenia, as well as those who have been sexually abused as a child. The DSM classifies Schizoid Personality Disorder as: â€Å"A. A pervasive pattern of detachment from social relationships and a restricted range of expression of emotions in interpersonal settings, beginning by early adulthood (age eighteen or older) and present in a variety of contexts, as indicated by four (or more) of the following: Neither desires nor enjoys relationships or human interaction, including being part of a family Almost always chooses solitary activities Has little, if any, interest in having sexual experiences with another person Takes pleasure in few, if any, activities with other people Lacks close friends or confidants other than first-degree relatives Appears indifferent to the praise or criticism of others Shows emotional coldness, detachment, or flattened affect B. Does not occur exclusively during the course of schizophrenia, a mood disorder with psychotic features, another psychotic disorder, or a pervasive developmental disorder and is not due to the direct physiological effects of a general medical condition.† Though there are several methods of treatment, most doctors suggest a short-term therapy/medication treatment, as long term can be difficult for the patient to remain motivated to continue returning and having unwanted social interaction. Seeing a psychologist allows the patient to open up and possibly become more comfortable with interpersonal communication, enabling a more personable identity. Those with SPD may demonstrate a vivid and wild fantasy life, and attain hobbies according to such. Things like video games, drawing, photography, and other solo activities are what interest SPD victims the most. Someone with SPD doesnt go out to social events, have intimate relationships, or even have many friends. Social interaction like that just isnt appealing to patients with SPD. They may never live a completely normal life with friends, a spouse, and other people to communicate with. However, this does not mean they arent happy. People with Schizoid rarely ever describe their life as â€Å"dull† or â€Å"boring†. Some patients tell of the immense pleasure they receive when making a job well done and finishing their work. Many are workaholics, and pour their heart and soul into every step of their careers. People with SPD are much more of a benefit to our society than some people may realize. Without the constant distraction of friends, relationships, and social events, they are able to concentrate on the task at hand. Whether it be a career or a simple arts and crafts project, concentration and focus go uninterrupted and can lead to a job very well done. I chose this topic because I had no idea what it was, and I wanted to learn more about it. I had no idea what I was getting myself into. Over the last few weeks I have been constantly studying this disorder and trying to get into the mind of someone with SPD. At first, it seemed hopeless. I couldnt seem to understand the idea of not having friends, or having never had a girlfriend. Social interaction like that had always been given in my life, and I couldnt imagine doing without. After further thought, however, I came to the conclusion that not only did they not want a physical relationship with others, they felt no need. If one can become completely content without the attention of others, then why bother yourself with the distraction? Though I havent personally spoken with someone with SPD, this is how I understand it. I feel as though they not only have no desire, they feel no need. Simple as that. A case study I found involved a middle-aged man named Mark and a peek into his life. He tells of his career, hobbies, and relationship with his family. â€Å"â€Å"Mark sits where instructed, erect but listless. When I ask him how he feels about attending therapy, he shrugs and mumbles OK, I guess. He rarely twitches or flexes his muscles or in any way deviates from the posture he has assumed early on. He reacts with invariable, almost robotic equanimity to the most intrusive queries on my part. He shows no feelings when we discuss his uneventful childhood, his parents (of course I love them), and sad and happy moments he recollects at my request. Mark veers between being bored with our encounter and being annoyed by it. How would he describe his relationships with other people? He has none that he can think of. In whom does he confide? He eyes me quizzically: confide? Who are his friends? Does he have a girlfriend? No. He shares pressing problems with his mother and sister, he finally remembers. When was the last time he spoke to them? More than two years ago, he thinks.He doesnt seem to feel uneasy when I probe into his sex life. He smiles: no, he is not a virgin. He has had sex once with a much older woman who lived across the hall in his apartment block. That was the only time, he found it boring. He prefers to compile computer programs and he makes nice money doing it. Is he a member of a team? He involuntarily recoils: no way! He is his own boss and likes to work alone. He needs his solitude to think and be creative.Thats precisely why he is here: his only client now insists that he collaborates with the IT department and he feels threatened by the new situation. Why? He ponders my question at length and then: I have my working habits and my long-established routines. My productivity depends on strict adherence to these rules. Has he ever tried to work outside his self-made box? No, he hasnt and has no intention of even trying it: If it works dont fix it and never argue with success.If he is such a roaring success what is he doing on my proverbial couch? He acts indifferent to my barb but subtly counterattacks: Thought Id give it a try. Some people go to one type of witch doctor, I go to another.Does he have any hobbies? Yes, he collects old sci-fi magazines and comics. What gives him pleasure? Work does, he is a workaholic. What about his collections? They are distractions. But do they make him happy, does he look forward to the time he spends with them? He glowers at me, baffled: I collect old magazines. he explains patiently How are old magazines supposed to make me happy?. †Ã¢â‚¬  As clearly demonstrated above, this patient displays no interest toward others socially. Though he has had an intimate relationship in the past, his concentration now pertains to his work and his sole hobby of collecting magazines. A workaholic, he prefers to work in solitude, as that is the only way he can think and be creative. His disbanded relationship with his family shows that even those supposed to be most important in ones life hold little to no importance. A seemingly uneventful life of routine is made enjoyable by his passion and innovation for his career. Without the distraction of social relationships, he is able to connect with his work and focus at a higher level. SPD not only allows for a better concentration level, it enables the patient to think more clearly, and with a better focus. As stated above, his life is almost completely centered around his career, something he seems to be rather proud of. Taking pleasure in his job lets him feel comfortable with his lifestyle and content with the choices he has made. In two separate studies, prisoners were examined on the validity of SPD. 556 male jail inmates in the United States participated in Study 1; 175 mentally disordered offenders in maximum security hospitals in the United Kingdom participated in Study 2. On both studies, scores on the Interpersonal Measure of Schizoid Personality Disorder (IM-SZ) showed reliability and patterns of correlations with other measures consistent with expectations. The scale displayed patterns of relatively specific correlations with interview and self-report measures of SZPD. In addition, the IM-SZ correlated in an expected manner with features of antisocial personality and with interpersonal behavior. In another study, 10 male individuals diagnosed with SPD were placed in a room together. Their behavior was recorded and later compared to an experiment under the same circumstances only with 10 seemingly normal men. The test subjects with SPD did not interact with one another for an entire half hour, until one of the men fell out of his chair and one of his colleagues helped him to his feet. This was a blind experiment, where the men involved did not know the others suffered from the same ailment. The men in the control group were quiet at first, but after the first 5 minutes they were all communicating with one another, talking about sports, family, and relationships.

The Organization Culture Of Deloitte Management Essay

The Organization Culture Of Deloitte Management Essay Organization consist the two types such as the profit organization and non-profit organization. A profit organization looking for the generate income and the profit share with the employees. In a profit organization, the company decides to keep and arrange the profit to the lender or keep invest in their own business. For an example, the Deloittes Northern Group made a  £2,329m for the year end of May. The group made a  £569m profit share to the partners and the average profit earned by each partner increased from  £758,000 to £789,000. A non-profit organization generally founded to serve a humanitarian. It channels the entire employees income into programs and service aimed at meeting or towards other issues such as deforestation and endangered species. Non-profit organization rely almost entirely on donation and grants from individuals, government entities and organization. For an example, Deloitte launched a Womens Initiative (WIN) in 1993. The WIN hosts more than 400 developments, networking and mentoring activities to help connections, strengthen skills and positively impact our organization and community. 2.1 The Types of Structure A recent article (Miranda Brookins) states that elements of organizational structure give companies effective and efficient ways to run their business, manage their employees and ensure that tasks are completed. Each element has its own benefit to impact the employee to achieve the organizations goals. The type of the organization structure involves the decisions about the work specialization, departmentalization, chain of command, span of control, centralization and decentralization and formalization. Work specialization It shows the degree to which tasks in the organization are divided into separate jobs with each step completed by a different person. It takes each task and assigns them to specific position. From a wider perspective, a job is synonymous with the physical and social aspects of the work environment. In contrary, the overspecialization can result in human diseconomies from boredom, fatigue, stress, poor quality, increased absenteeism and higher turnover. For example, an employee specializes in auditing skill but Deloitte should manage the employee to the audit department to exert his/her professional skill to the company. Departmentalization It based on the jobs are perform in the group together. Even though, Deloitte also has its own specific way of classifying and grouping work activities. The departmentalization creates the types of the execution based on the work of the employee assign their own product or brand with the geographical of customer demand. Departmentalization grouping jobs by the functions performed, product line, the basis of territory, the basis of product and the type of customer and needs. Chain of Command It shows the continuous line of authority that extends from upper levels of an organization to the lowest level of the organization and clarifies who reports to whom. There are three importance concepts to attach with theory such as authority, responsibility and unity of command. The authority shows the rights inherent in a managerial position to tell people what to do and to expect them to do it. Then the responsibility shows the obligation and expectation of the leaded to perform for the organization. The last, unity of command is the concept that a person should have one boss and should report only that person. For an example, the video conference of Deloitte should be the chairman from the head office to take over to all branches. Span of control It determines the number of employees who can effectively and efficiently supervised by a manager. It needs the number of managers an organization needs which based on the number of employees and departments a company has. Centralization and Decentralization Centralization shows the degree to which decision making is concentrated at upper levels in the organization. Organization in which top managers make all the decision and lower-level employees simply carry out the order. Besides that, decentralization shows the organization in which decision making is pushed down to the managers who are closest to the action. An article (Osmond Vitez) said that centralization develop the companys mission and vision, and set objectives for managers and employees to follow when achieving these goals. Decentralization organization utilizes individuals with a variety of expertise and knowledge for running various business operations. Formalization It shows the jobs within the organization are standardized and the extent to which employee behavior is guided by rules and procedures. A highly formalized jobs offer little over what is to be done and the low formalization means fewer constraint on how employees do their work. For example, the IT department of Deloitte format up the time of the connection to each branch and the performance of the video conference. So that, the interviewer wont waste the time to wait for the connection and can arrange the accurate time to arrive the room. 2.2 Organization Culture Organization culture is a system of shared meaning and common beliefs held by organizational member that determines in a large degree and how they act towards each other. The implication of culture is a perception, shared and descriptive. The values, symbols, rituals, myths a practices are the way that the people do the things around here. Innovation and Risk taking According to Robert F. Brands (13, August 2012), an effective innovation leader should encourage creativity and risk taking, while also practicing a tolerance for failure. The setting and agreeing on the risk taking bandwidth help to practice the leader recognized as a learning experience when the process had failure. For an example, in 20th November 2012 a leader of Deloitte named Gartner evaluates on the ability to articulate logical statement about current and future market direction, innovation, customer needs and competitive forces. At the same time, consultants are rated on their understanding of how market forces can be exploited to create the opportunities to the provider. Attention to details It is a degree to which employees are expected to exhibit precision, analysis, and attention to detail. It defined the organization look more details to accurate the values of the organization comprise with the organization culture. For an example, the senior manager of Deloitte, Kurt Hauermann looks for the data risk management, data management technology and data governance as the dimensions that uniquely combine to deliver business value. Outcome Orientation It is a management focuses on the result rather than on processes used to achieve them. It extends into the workplace, and employees are reviewed regularly on a performance basis and the only thing that matter is the end of the result. People orientation People orientation takes into consideration the effect of outcome of people within the organization and it is also sensitive to individual with the decisions. The culture cares at the employee in the organization. For an example, Deloitte believes that the employees can do their best work when they growth and know the value. Besides that, Deloitte has 148,000 people work in 150 countries in the organization and the developing talent is a top priority because people are the very reason client service excellence is a hallmark of Deloitte. Team Orientation It defined the works organized around teams rather than individual. A recent article (Donna Eigen) shows that there are number of tactics that can foster a team orientation, from team building and diversity workshops to retreats, merit system that identify and recognize team-oriented behavior and processes that facilitate project teams. Aggressiveness It determined that the employees are expected to be competitive rather than easy going. It looks for the immediate results and lead to immediate reward. In June 2012, Deloitte discuss about the objectives of transparency and financial stability is often seen as being juxta-positioned. The impact on the public policy objective debate and highlighted the question of the interaction in the financial of Deloitte. Stability It means that the organization activities emphasize maintaining the status quo rather than change. In New York, 16 March 2012, Deloitte welcomes the Financial Stability Boards call to improve the dialogue between external auditors and prudential supervisors and regulators of financial institutions in the wake of the recent global financial crisis. 2.2.1 Relationship between organizational structure and culture The organizational culture develops around the structure and the organizational culture can change when the management changes the worker to assign to the roles in the same structure. According to Shane Thornton (April 18, 2012), an organizations culture is an informal, collectively held grouping of ideas and values, as well as the type of workplace relationships and ways of doing things within the organization. Organizational structure is the way to arrange the management and the lines of the authority. It determines the performance within the company and helps the organizational culture run with the efficiency and consistency to create its own organizational culture. Conclusion At the end in this task, it defined the profit organization and non-profit organization of Deloitte. Besides that, it shows the specialization, departmentalization, chains of command, spans of control, centralization, decentralization and formalization of Deloitte. After that, it shows the organization culture such as attention to details, team orientation, people orientation, outcome orientation, aggressiveness and stability of Deloitte. Finally I show the relationship between the organization structure and culture. Introduction It defines the functions of the management within the Deloitte. And list the approaches of the leadership of Deilotte. 3.0 Management Management involves coordinating and overseeing the work activities of other so that their activities are completed efficiently and effectively. It performs the managers function within the Planning, Organizing, Leading and Controlling. Planning Planning defined the goals, establishing strategies to achieve goals, developing plans to integrate and coordinate the activities within the company. It is close connected with the creativity and the innovation, it also set up the objectives and develops the appropriate course of action to achieve these objectives. For an example, Deloitte plans to get a new video conferencing system to get close and communicate easily with all foreign branches to get the high decision making. Organizing It is arranging and structure work to accomplish the organizational goals. It shows that how the leader organize the team to achieve the goals according to the plans. Besides that, Deloitte organized the Nortel Network Ltd to apply the video conferencing system and the Nortel Network Ltd will carry on all the setting and performing of the video conferencing system. Leading It defined the working through people to accomplish goals. It means how the leader uses their skill to lead the group to achieve the goals and the successful. Leading requires to coach, assists, and problem solve with employees. Then, the Deloitte decided who will attend the video conferencing to get the decision making. Controlling It is a continuously work to monitoring, comparing, and correcting work to check the result against goals and make sure that it is following the plan. After that, Deloitte will use the video conferencing to control the branches performances and has a close contact with the branches. 3.1 Leadership Leadership is the art to motivate the group to against the goals. A recent article (Susan Ward) states that effective leadership is based upon ideas, but wont happen unless those ideas can be communicate to others in a way that engages them. Different managers can employ the different strategies to lead the employees to against the goals. According to David Ingram, transformational and transactional leadership are polar opposites when it comes to the underlying theories of management and motivation. Transformational Leadership It determined the management of the day-to-day operation and crafts strategies to the next level of performance and success. It will provide the opportunities for personal and professional growth for each employee if the transformational leader sets goals and incentives to push their subordinates to the higher performance levels. For example, in 1June 2011 Barry Salzberg is the global Chief Ececutive Officer of Deloitte Touche Tohmatsu (DTTL), he sets the strategies direction of the Deloitte global network and it comprises 47 member firms operation in 150 countries with approximately 200,000 people. Transactional Leadership It defined the normal flow of operations by more concerned with maintaining. The leader will use the rules to motivate employees to perform at their beast. It wont care in strategically guiding an organization to a position and these ledgers are solely concerned with conform all the performance flow. For example, Steve Almond is the Chairman of Deloitte Touche Tohmatsu Limiteds (DTTL) Global Board of Directors. He had served as Managing Partner of International Markets at Deloitte LLP in the United Kingdom and he looks after Deloitte United Kingdoms International relationship and activities. Conclusion At the end, it also shows the planning, organizing, leading and controlling based on the Deloitte and it determined the transformational leadership and the transactional leadership with Deloitte. Introduction It is going to discuss about how does Deloitte motivate and perform their employee to work for them. It defines the ideas that Deloitte provide to motivate to work hard to get the advantages. 4.0 Motivation and Performance Motivation is the process that account for an individuals intensity, direction and persistence of effort toward attaining the goals. An article (Kendra Cherry) states that motivation involves that the biological, emotional, social and cognitive forces that activate behavior. It describes the purpose that the person does something. The article from Deloitte (Ivana Ã…ËÅ"à ­hovà ¡, FinanÄ nà ­ management, May 2009) states that the motivation and compensation are part of a  series of articles focused on performance management where Deloitte experts introduce individual components of the integrated performance management system in companies. This article deals with motivation and compensation. According to the official website of Deloitte within the Human Capital, it states that they using the motivation tools available to a financial and non-financial and it also determined that if the employees do not feel close to the strategys value and direction and motivates to fulfill the companys designed goals, the company is not likely to successfully reach its goals. From the Deloittes official website, the financial rewards and financial compensation system are the motivation tools available to the employees of the Deloitte. A recent article (Carol Bainbridge), states that extrinsic motivation refers to motivation that comes from outside an individual and the motivating factors are external, or outside, rewards such as money or grades. Deloitte believes that the rewards system is the right driver to the employees perform the work commitment and employees performance. However, attention should be paid to non-financial incentive tool. It is more difficult to define these tools as an important role to motivate employees to perform. Broadly speaking, they can be included in the corporate culture. The reason is often the corporate culture which the employee expects in the company of their choice. Figure 1. Relationship between the employee and the wage the employee received of the Deloitte From figure 1, the employees quality is reflected in a certain component of the employees compensation. According to the performance management of Deloitte, they consider that the compensation aligned with success in fulfill the goals of the company and often also the goals of the team and the individual. So from the figure 1, Deloitte use the proportion of the individual components of the employee total based on the job and the job description. Besides that, Deloitte indicate the high position of the employee in the structure will get the high proportion. Conclusion At the end, Deloitte use the rewards and compensation to motivate the employee to work hard and show the benefit of the reward and compensation to drive the employee work hard. Introduction It is going to show what technology that Deloitte used to communicate to the foreign branches and its functioning. 5.0 The impact of Technology on Deloitte A technology system can drive an organization to efficiency and effectiveness. The efficiency based on how we do the things right so the organization wont waste the time to delay achieves their goals. Besides that, the effectiveness is defined to do the right things, it show that the organization know what they want to do. The case study from the assignment, it shows that the video communication is the way that the Deloitte costs down through the video communication when they reach more employees and branches. Video communication can help to cut down many costs such as traveling cast. According to the Yezdi Pavri (managing partner for Deloitte Canadas Toronto office), he said that being able to meet clients and colleagues in real time without travel is an efficient, effective and environmentally considerate way to address their needs. In a high telepresence room, all the branches who in the different country appear very close and the experience can get with being there with face to face. Nortel Network Ltd is a multinational telecommunication equipment manufacturer in Canada. Deloitte had chosen Nortel Networks Ltd to manage the service of the video conferencing. In a result, Nortel said that in a statement that a company that spends $23 million a year on travel can use telepresence and videoconferencing to recover 385,000 hours of lost productivity reduce its carbon footprint by up to 4,200 tons and save up to $7 million in U.S. dollars. So, the video conference can be more environmentally considerate and go to the green innovation. In contrary, video conferencing also has its disadvantages be the barrels to communicate with each other. Deloitte has 600 offices in more than 150 countries so the time equation is the barrel that Deloitte communicate with the foreign branches. Sometimes, if unlucky have an emergency problem and the branches of England need to contract to the Singapore branches; it may be will fail to get a communication because the time between England and Singapore differ at least 8hours. Besides that, installations of the technology in video conference need a high tech equipment to fix it. For Deloitte, if needs to install the equipment, Deloitte needs to pay for the head office and the all branches. Many feathers make a bed; Deloitte has more than 600 offices in the foreign countries. So Deloitte needs to pay for the payment within these more than 600 offices and it will become a huge expense. Conclusion Finally, it shows the Deloitte uses the video conferencing to communicate to the foreign branches. It also shows that the effectiveness and the efficiency of Deloitte. Besides that, it also consists the advantages and disadvantages of video conferencing.

Origin And Applications Of Formwork Construction Essay

Origin And Applications Of Formwork Construction Essay Formwork is the term given to either temporary or permanent moulds into which concrete or similar materials are poured. In the context of concrete construction, the false work supports the shuttering moulds. Most of the buildings which are made to stand for a long time are made of concrete and mortar. These building materials are strongest and most suitable but at the same time they are a bit tedious to deal with. They do not acquire the desired shape and need help of some sort of support or any frame which can be detached as the concrete solidifies. Actually concrete is a material without any shape. For most applications the shape matters, and concrete has to be molded or formed. ORIGIN Concrete has been in use for the thousands of years. The dome of Pantheon in Rome is made of lightweight concrete, and the under face shows the moulding effect of formwork used two millennia ago. But it was only at the end of nineteenth century that the use of concrete became common, with the invention of reinforced concrete. Some of the earliest examples of concrete slabs were built by roman engineers. Because concrete is quite strong in resisting compressive loads, but has relatively poor Tensile strength, these early structures consisted of arches, vaults and domes. To mold these structures, temporary scaffolding and formwork built in the future shape of the structure. These building techniques were not isolated to pouring concrete, but were and are widely used in Masonry. Because of the complexity and the limited production capacity of the building material, concretes rise as a favored building material did not occur until the invention of Portland cement and reinforced concrete. Pantheon Dome SIGNIFICANCE The construction industry forms the largest single sector in any economy. In the USA for example the construction sector is responsible for 14% of the GDP (US National Statistics Bureau). Formwork is the single largest cost component of concrete buildings structural frame. The cost of formwork exceeds the cost of concrete or steel and in some situations the formwork costs more than the concrete and steel combined. For some structures, placing priority on the formwork design for a project can reduce the total frame cost by as much as 25%. This saving includes both direct and indirect costs. Formwork efficiencies accelerate the construction schedule, which can result in reduced interest costs during construction and early occupancy for the structure. Other benefits of formwork efficiency include increased job site productivity, improved safety, and reduced potential for error. Concrete is a material without shape. For most applications the shape maters and the concrete has to be molded or formed. Formwork is one of the integral parts of construction industry. This is the basic of any architectural structures on which the whole building is made. The formwork is basically used to hold the whole structure until the whole building is capable to stand on its own. Even we use some solid iron rods in buildings but the concrete need some time to bind with that for a firm structure to stand as and in the desired shape. CLASSIFICATION OF FORMWORKS Under this section of the study we will get in depth of four aspects of each and every type of the form work. These four aspects would be: Analysis of various components of formwork. Safety aspects of formwork. Economy aspects of formwork. Selection process of the material of formwork. The formworks are broadly divided in four categories based on the material, of which it is made. This categorization is as follows: Timber Formwork. Metal Formwork. Plastic Formwork. Fiber Formwork. TIMBER FORMWORK This is the oldest kind and most basic formwork used in the construction industry. Its moisture resistant property makes it utilizable in this industry. Though it is easy to manufacture the timber formwork but it is time consuming when formwork is to be prepared for big structures. It is relatively cheap and easy to shape as required. It is relatively light in weight for handling, but it is of limited durability. ANALYSIS OF VARIOUS COMPONENTS: Sheathing is supported by horizontal members called joists or runners. Joists are made from dimension lumber spaced at constant intervals that are a function of applied loads and type of lumber. It is a recommended practice to round down the calculated joist spacing to the lower modular value. Joists are supported by another set of horizontal members perpendicular to the joists, called stringers. The stringers are supported by the vertical members called shores. In all wood conventional formwork [ i.e. 4 4 in. or 6 6 in.]. Shores are rested on heavy timbers called mudsills, to transfer the vertical loads to ground. In case where a slab on grade exits, shores are directly rested on them. Once the bottom of the beam is constructed and leveled, one side of the beam is erected first with the holes drilled in it for installing the tie roads. Tie rods are steel rods that hold the two sides of beam together. After the first side of beam form is erected, the reinforcement is placed inside the beam and then the other side of the beam is erected. Tie rods are then inserted into all holes on both side of the beam. The tie rods function is to resist horizontal pressure resulting from the freshly put concrete and thus keep the sides of the beams in their proper location. SAFETY ASPECTS FOR TIMBER FORMWORK: Though Timber formwork is the basic formwork but it has some drawbacks relating to the safety which prove to be harmful for the structure to be build and the laborers. The following safety aspects must be considered while dealing with the Timber Formwork. Care should be taken in presence of Moisture: The biggest disadvantage of Timber Formwork is that the timber get softens when it is wet. If the moist is too much then timber soften up to a extent that it can be poked with the help of nail tip. Though dry timber is hard enough to bear the stress developed by concrete but it is not the same when it get wet. When timber comes in contact with moisture, the methanol molecules get activated and are responsible for weak intermolecular bond and thus softening. This problem is commonly known as Wet Rot. Care should be taken in presence of mini organisms and micro organisms: Biggest threats to any wooden structure and article are Termite and Fungus. Both of these organisms live on almost every type of wood as parasite and cause damage to huge quantity of wood. As far as Timber formwork is considered the damage occurs mainly in damp and dark regions of storage. Termites eat the wood from the inner side making it hollow and weak within. The wood thus left is so weak that it can be broken with bare hands. The damage caused by fungus is known as Dry Rot. Dry-rot fungus is often thought of as a building cancer, rampaging through buildings and rapidly destroying any timber in its path. The fungus, which thrives in moist unventilated conditions, will penetrate brickwork to get to more timber and can cause widespread destruction of structural timbers, skirting boards and door frames, and wood flooring. In short, the fungus can be thought of as living in masonry and eating wood, and because t he fungus thrives in damp, unventilated conditions, it can occur in the areas of a property that are not often seen, such as floor voids, or behind timber paneling, so damage may be extensive before the attack is discovered. Fire Safety: We already know that wood is flammable and porn to fire if considerable precautions are not taken specially for those constructions sites which are near by to a gas station or any such location. Fires on construction sites have, for many years, been recognized as a serious problem for construction companies and insurers, but less of a public safety issue since there are relatively few fire deaths in such incidents. However, the trend for ever-taller buildings, particularly in the Gulf and Far East, has resulted in a number of significant fires during construction which have caused deaths and demonstrated the difficulties facing fire brigades when tackling such incidents. On several occasions, helicopters have had to be used for fire suppression and rescue. Insurers have long had concerns about the potential for loss on tall building projects, and these fires have demonstrated that their concerns are well founded. Causes can involve electrical risks, hot work, smoking, rubbish burning, overheating equipment and escapes of gases or flammable liquids all of which are well recognized and should be amenable to normal fire safety measures. DIFFERENT TYPES OF TIMBER FORMWORK Plywood: plywood has some strength in both directions, but because the outer veneers give greater strength in the direction of their grain, the sheet should always span that way. Plywood is a few millimeters thick used as lining material, which is fully supported from behind. With thickness of 12-19 mm the strength of plywood itself can be used, and the framing members spaced out the economical distances. There are three main types of poly wood: Finnish Birch American Softwood Tropical Hardwood Sheets are normally 8ft by 4ft except for Finnish Birch, the outer grain runs in the length of the board. The first two types are produced to appropriate national standards. Hardwood ply comes from a variety of tropical countries so obtaining reliable data about them is difficult. Block board: Stripes of timber are made into a panel with veneers on both sides. The glue should be of high quality else the surface may not be flat enough as the stripes tend to show through. Block board is made up of a core of softwood strips. These strips may be up to about 25mm wide. The strips are placed edge to edge and sandwiched between veneers of hardwood. The sandwich is then glued under high pressure. Block board is not suitable for outdoor use because the glues used are interior glues. It is important to ensure that the core runs lengthways in order to achieve maximum strength. The core can be joined by hands or by machine. There are only few small core gaps or even no core gaps in machine-made core. But core gaps are common in man-made cores. Machine-made core is much better than man-made core. Block board is sold in sheets of 2440 x 1220mm and are normally 30mm thick. Screws and nails may be used to attach block board but you have to ensure that you make contact with th e strips of softwood and not the gaps between the softwood strips. Chipboard: Small chippings are pressed into sheets. As with all boards depending significantly on plastic as the matrix, the stiffness is poor, and a greater thickness than plywood is frequently needed. It is heavier than plywood but give better finish. Gluing together wood particles with an adhesive, under heat and pressure makes chipboard. This creates a rigid board with a relatively smooth surface. Chipboard is available in a number of densities: -normal, medium and high-density. METAL FORMWORK This kind of Formwork is the most suitable formwork for high rise buildings. This system is eco friendly and proves to be more economical on long run due to good durability. In the conventional metal system, joists and stringers are made of aluminum or steel supported by scaffold-type aluminum or steel shoring. In todays construction practices, joists and stringers are made of aluminum and are supported by scaffold-type movable shoring system. This formwork is built out of prefabricated modules with a metal frame (usually steel or aluminum) and covered on the application side with material having the wanted surface structure (steel, aluminum, timber, etc.). ANALYSIS OF VARIOUS COMPONENTS: In this system, steel joists and stringers have the advantage of supporting greater spans and fewer joists and stringers. The main problem with using steel as joists and stringers for forming concrete slabs is their heavy weight, which makes it difficult for one person to handle. A standard steel W-section is used because its wide flange makes it easy to connect stringers with shore legs. A composite action open-web steel joist, supporting beams and girders, and reinforced concrete slab interconnection. Upper apex portions of the steel joist webbing protrude through the upper chord members of the joist and through apertures provided in the sheet metal formwork placed over such joists prior to the pouring of the concrete slab. The improvement relates to a continuous round rod secured near the apex of each projecting web member parallel to the longitudinal axis of the joist and a reinforcing wire mesh draped between said rods, thus permitting greater spacing between said joists, whereb y said protruding apex portions, said rods and said draped wire mesh will be encased within the slab to act as shear interconnection and reinforcement devices therein, to secure the joist and formwork together, to enhance the locking of the concrete slab to the protruding joist apex portions, and to the supporting beams through the joist end connection welded to the beam or girder, and to reinforce said concrete slab. This improvement makes optional the use of wedge members forced between such protruding joist apex portions. SAFETY ASPECTS OF METAL FORMWORK Though there is no need worry for any fungal or organic decay to the metal formwork but still there are same issues which must be paid attention to, relating to corrosion and careless handling. Now lets discuss these issues one by one. Corrosion: the corrosion problem may occur to any formwork if it is not maintained in proper way. Any part of formwork may be corroded due to direct contact with moisture. This direct contact is either because of lack of proper oiling techniques or due to standing water. If even an inch or even a centimeter is left out of oiling then it proves to be dangerous for the formwork. Many times it happens that water is leaked out and left standing. This tends to corrode the dipped part of formwork. Rusting of formwork also leave stains over the concrete unit. These stains if thick, crystallize later and pose a threat to plater layer. Mishandling while assembling: There have been several cases causing accidents of laborers at the site due to mishandling of the formwork. These accidents occur while lifting, if the load is not properly tied or hydraulic jack is not applied properly. Other reason responsible for on site accidents is loose screws and bolts which lead to collapsing of the erected formwork. Electricity: If the site location is nearby any sort of electric network then the metal formwork should be handled with utmost care. A safe distance should be maintained and if possible any such network or device should be avoided in nearby vicinity of the site. DIFFERENT TYPES OF METAL FORMWORK Extruded Aluminum Joist: The first component of the conventional metal system is the aluminum joist. The extruded aluminum joist takes the shape of a modified beam with a formed channel in the top flange in which a wood nail strip 2 by 3 in. is inserted. Tha plywood deck is then nailed to the nail strip. Aluminum Beams (Stringers):The purpose of stringers is to transfer the loads of the surface panel to scaffold. Extruded aluminum joists can also be used as stringers unless the loading is too excessive, in fact it is good practice to avoid using a mixture different beam types. Aluminum beams are commercially available for the lengths ranging from 4 to 30 ft. Aluminum Scaffolding Shoring: The aluminum scaffolding shoring system has been available for several years as a substitute for the steel scaffolding shoring system. The system consists of several frames connected together by cross bracing. Aluminum shoring is lighter and has load carrying capacity equal to or greater than steel shoring. Load carrying capacity of aluminum shoring can reach up to 36,000 lb. Fig 10 Aluminum Scaffolding Shoring Post share: A Post Shore is a single member made of steel or aluminum and support stringers. Post shores can be used to replace, or in combination with, scaffold shoring. Post shores can also be used re-shoring after striping of formwork elements. ECONOMY OF FORMWORK The concrete subcontractor must achieve 3 goals in his formwork workmanship: Quality formwork must be designed and built so that the resulting cast concrete attains the desired size, shape, position and finish. Safety formwork must be designed built strong enough to support all dead and live loads without blowouts, collapse, danger to workers, and risk of damage to the structure. Economy formwork must be designed, built and re-used in an effort to save time and money for the general contractor and the owner. Now as far as the economical aspect of formwork is concerned let me make you aware of the fact that formwork share a considerable site budget. If we design the formwork intelligently and plan its use, then we can save a lot of money. As metal formwork is more durable and reusable as compared to the wooden formwork, it should be used. There are several advantages which make metal formwork a better option.

Animal Farm, by George Orwell Essay -- Animal Farm Essays

In the novel Animal Farm by George Orwell, the pig Napoleon uses specific tactics to gain power and control over the animal farm. Some of these techniques include controlling information through education, scapegoating, use of fear, swaying public opinion and blind obedience. Throughout the novel, the most prominent way that Napoleon gained power was through controlling the education that the animals received. In the beginning of the novel, Snowball believes in educating all of the animals on Animal Farm, young and old, by trying to organize committees and instituting classes devoted to reading and writing (page 39). However, Napoleon openly states that educating the young is more important that the old. When Jessie and Bluebell have puppies, Napoleon takes them away and secludes them from the rest of Animal Farm to teach them on his own (41). Throughout the novel, after Snowball's removal, education becomes less and less important, and pigs and dogs are the only animals really being taught anything. This comes in handy for Napoleon as he begins to make "adjustments" to the rules that Animal Farm is based upon, such as drinking alcohol, sleeping in beds, and walking on two legs. The fact that the animals can't do math is an advantage as wel l when Squealer starts reeling off facts and figures about rations and death rates and other nonsense (105). Another technique Napoleon takes advantage of is scapegoat...

Utilization of 14c Phenylalanine Derived from Arylphorin or Free Amino

UTILIZATION OF {14C} PHENYLALANINE DERIVED FROM ARYLPHORIN OR FREE AMINO ACID IN MANDUCA SEXTA PHARATE ADULTS GENERAL INTRODUCTION TO THE PAPER How did someone figure out that carbon dioxide in the bloodstream is exchanged for oxygen in the lungs of mammals? And how do we know that hormones are produced by, for example, the pituitary gland and, moreover, that these hormones signal the body to grow. These and many other questions have been answered by means of the scientific method. Scientists form hypotheses, experiment, collect data, and draw conclusions from this data that is then applied to answering questions about that certain topic. Some research seems to be obselete and/or practically useless, only to come into the picture years or decades later and shift the field of science. Although at times it is difficult to say what the repercussions of a particular study will be, it is not uncommon for that very study to play a key role in a major scientific breakthrough later. Therefore, it is important to keep in mind that although a particular study may not seem to be important at the time, later it could be the most signifi cant study in the field. This study performed by Min Wu and Dr. Marc E. Tischler, at first glance may appear to have a narrow focus, but upon furthur consideration, one realizes that its findings have applications to any number of related topics. In this experiment, Wu and Tischler tracked what paths a specific protein, arylophorin, and followed its production and distribution throughout the body of Manduca sexta pharate adults. Their first goal was to determine the most efficient method for producing radioactively labeled arylophorin, called 14C-Arylphorin.

After much experimentation it was determined that incubating one-half fat body in 1 ml of medium (0.15 mM of labeled phenylalanine and amino acids at 25% normal level in Grace's medium) for 15-24 hours, chasing labeled phenylalanine after one hour with unlabeled phenylalanine, yielded most desirable results. Temperature was shown to have little or no affect on the results, so room temperature was used in further experimentation and final implementation in achieving high specific activity (more convenient).

“A Very Old Man With Enormous Wings” by Gabriel García Márquez Essay

When Pelayo was coming back to his house, he found an old man face down in the mud, with a pair of enormous wings. The neighbor told them he was an angel, and must have been knocked down by the rain. In the short story, â€Å"A Very Old Man With Enormous Wings†, Gabriel Garcà ­a Mà ¡rquez reveals some of his ideas of human nature. He shows how pessimistic humanity can be, through an experience with a fallen angel. One portrayal found in the story was the idea of human greed and selfishness. Most people are interested in what is best for them, or how they can take advantage of something for their own good. In the story, the Pelayo and Elisenda, husband and wife, had an angel fall into their yard. At first they were going to put the angel on a raft and free him from their chicken coop prison. Instead, they decided to charge admission to see the fallen angel that they held captive in their courtyard (6). They knew that people would come from everywhere to see this spectacle, and took advantage of the situation. By keeping this angel locked up in the chicken coop, they were profiting off of his misery. The people that came complained of their many problems, and were looking for the angel to help them. They were all concerned with themselves, and their own problems, rather than the angel’s well being. This selfishness is just part of human nature. The human race will always look for the best options to benefit themselves. Humans seem to have a very short attention span. The smallest things can be amusing, and keep our attention, but generally only for a short time. The human race is always looking for the new best thing, whether it is the hippest fashions, the newest, fastest cars, or the top-of-the-line computers. In â€Å"A Very Old Man With Enormous Wings†, the people were amazed by the fact that a â€Å"flesh-and-blood angel† had fallen, and were coming from all over to see him. It was only after a period of a few weeks or so that a traveling circus came to town. In this circus, there was a woman who was supposedly turned into a spider for disobeying her parents. The crowd lost interest in the angel and swarmed to see the spider lady (10). The people were interested in this angel for only a short period of time because something more interesting came to town. The whole idea that there was a fallen angel on earth became old news. Humanity is, by nature, cruel. Again, going back to the angel and his imprisonment, it seemed as though people were upset or disappointed that the angel would not answer their questions. The whole imprisonment was cruel to begin with. At first, they even tried to feed the angel mothballs. Then, when everyone was dissatisfied with the angel merely lying around in the chicken coop, they decided to get him to move by burning his side with an iron, used for branding steers (9). For weeks they tormented this poor, hopeless angel. Mà ¡rquez, through his fiction, has shown some of his feelings on the philosophy of human nature. He feels that as a whole, is not very positive, and can be quite selfish. We tend to have a short attention span with many things, and we can also be very cruel. Human nature, as portrayed in â€Å"A Very Old Man With Enormous Wings†, is not as perfect and wonderful as many would like to believe.

Educational Changes in the Schools Essay

The educational system is viewed to be an important aspect for the progress of each individual and the society as a whole. Through the involvement with the educational system, each individual personal skills and potential are harnessed and further developed to be used as his or her medium for attaining greater things in life in certain fields such as exploration, discovery, development and others. The progress reflected from the historical basis of the society shows that the civilization has greatly developed transcending the numerous boundaries that their primitive self has and this is mainly attributed to the constant pursuit of knowledge by the people through their educational system. However, in the present, the educational system of the society is faced with numerous problems and challenges, which often negates their benefits and effectiveness it has on the concern of personal and social development. People often argue that these problems are the result of the lack of change in the educational system over the last decade. Indeed, on some aspect, this argument is true as some of the concern and fields in the educational system remains constant over the years thus, unable to cope with the changes in the social condition resulting to certain problems and complications. The social condition over the years is rapidly changing such as problems of poverty, overpopulation, government and military issues and others, and these primarily affect the involvement and the practical application of the educational field in the society. The inability of the educational system to cope with and address the dominant social problems resulting to its ineffectiveness to promote development within an individual and the society he or she is involved in. However, the educational system over the years has also changed addressing and incorporating most of the critical social problems and condition in its concern resulting to the progress that is has already founded over the century. Comparing the face of the educational system in the past with the present will present important insights regarding the development that the said field has already taken to promote further its effectiveness and influence. The educational systems has developed new aspects in its field such as scholarship and financial assistance for poverty issues, new facilities and modernized equipments to cope with the rapid influx of its student population, modernized subjects and courses to address the new trends and needs, and others. If one will consider the problems in the educational system, these are rooted in the perspective and opinion of the people towards the influence of the said field and not in the system of the schools in the present. Education sometimes becomes ineffective not due to its inefficiency but because people negate and disregard its importance. Generally, the field of education is constantly changing and developing further for the promotion and expansion of its benefits and positive influence. Over the century, the educational system has grown and progressed aiding the society to develop into its modernized present self.
