Interracial Marriage Under Apartheid

Interracial Marriage Under Apartheid Officially, there  were no interracial marriages under Apartheid, but in reality, the picture was much more complicated. The Laws Apartheid rested on the separation of races at every level, and preventing interracial sexual relations was an essential piece of that.  The Prohibition of Mixed Marriages Act from 1949 explicitly prevented white people from marrying people of other races, and the Immorality Acts prevented people of different races from having extra-marital sexual relations. Moreover, the 1950 Group Areas Act prevented people of different races from living in the same neighborhoods, let alone the same house. Yet despite all of this, there were some interracial marriages, though the law did not see them as interracial, and there were other couples who broke the Immorality Acts and were often jailed or fined for it. Unofficial Interracial Marriages Under Apartheid The Prohibition of Mixed Marriages Act  was one of the first steps in setting up Apartheid,  but the law only criminalized the  solemnization  of mixed marriages, not the marriages themselves.  There were a small number of interracial marriages prior to that law, and while there was not much media coverage given to these people during Apartheid, their marriages were not automatically annulled.   Secondly, the law against mixed marriages did not apply to non-white people, and there were proportionally more interracial marriages between people classified as â€Å"native† (or African) and â€Å"Coloured† or Indian. While there were in effect mixed marriages, the law did not see them as interracial. Racial classification under Apartheid was based not on biology, but on social perception and one’s association. A woman who married a man of another race was, henceforth,  classified as being of his race. Her choice of husband defined her race. The exception to this was if a white man married a woman of another race. Then he took on her race. His choice had marked him, in the eyes of white Apartheid South Africa, as non-white. Thus, the law did not see these as interracial marriages, but there were marriages between people who prior to the passage of these laws had been considered to be of different races. Extra-Marital Interracial Relations Despite the loopholes created by pre-existing mixed marriages and non-white interracial marriages, the Prohibition Against Mixed Marriages and the Immorality Acts were strictly enforced. White people could not marry people of other races, and no interracial couples could engage in extra-marital sexual relations. Nonetheless, intimate and romantic relationships did develop between white and non-white or non-European individuals. For some individuals, the very fact that interracial relations were so taboo made them appealing, and people engaged in interracial sexual relations as a form of social rebellion or for the excitement it offered.  Interracial relations came with serious risks, though. The police followed people who were suspected of engaging in interracial relations. They raided homes in the night and inspected bed sheets and underwear, confiscating anything that they thought showed evidence of interracial relations.  Those found guilty of violating the Immorality Acts faced fines, jail time, and social censure. There were also long-term relationships that had to exist in secret or be camouflaged as other types of relationships. For instance, most domestic workers were African women, and so an interracial couple could camouflage their relations by the man hiring the woman as his maid, but rumors often spread and such couples were also harassed by the police. Any mixed-race children born to the woman would also provide clear evidence of an interracial relationship.   Post-Apartheid Interracial Marriages The Prohibition of Mixed Marriages and Immorality Acts were repealed in the mid-1980s during the loosening of Apartheid. In the initial years, interracial couples still faced significant social discrimination from all races, but interracial relations have become more common as the years pass.  In recent years, couples have reported far fewer social pressures or harassment.

Psychology (humanistic counseling) Essay Example | Topics and Well Written Essays - 1500 words

Psychology (humanistic counseling) - Essay Example Even the most advanced computers have trouble understanding the meaning of a simple story or conversation. Cognitive psychologists have found similar complexity in other mental processes. Developmental Psychology is the studyofchangesin human behavior and thought from infancy to old age. Developmental psychology is the study of how people change over time, but it also investigates how and why certain characteristics remain consistent over the life course. A child changes dramatically in size, physical coordination, and thinking capacity while maturing into an adult, for example, but may also maintain the same basic temperament while growing up. Traditionally,developmental psychologists have focused on child development, believing that most formative experiences of life occur during infancy and childhood. The early years are indeed a time of extremely rapid development, when children acquire motor skills, thinking abilities, social skills, capacities for feeling and regulating emotion, and other characteristics that will last a lifetime. But psychologists have more recently turned their attention to adolescence and adulthood, recognizing that development continues throughout the life span. The study of adult development focuses on the unique experiences of this stage of life and examines how adults maintain and refine their capabilities as they age. Thestudyofhumandevelopment requires an especially broad and integrative approach. Thus, developmental psychology incorporates ideas from almost every other area of psychology, including social psychology, cognitive psychology, biopsychology, clinical psychology, and educational psychology. It also draws from many other fields concerned with human behavior. These include sociology, biology (especially genetics and evolutionary biology), anthropology, and economics. The variety of fields relevant to developmental psychology reflects the complexity of human growth and change.(Microsoft Encarta 2007 1993-2006 ) 3. Biological Psychology Biopsychology, is thescientificstudy of the biology of behavior and mental processes. People also refer to this field as biological psychology, psychobiology, behavioral biology, or behavioral neuroscience. Thetermbiopsychology denotes a biological approach to psychology, rather than a psychological approach to biology. Most biopsychologists are trained experimental psychologists who have brought their knowledge of biology to the study of psychological phenomena. These phenomena include behavior and underlying psychological processes, such as learning, memory, perception, attention, motivation, emotion, and cognition. Biopsychologistswork in a variety of overlapping fields of study. Scientists in cognitive neuroscience primarily study the brain to understand the neural mechanisms of mental processes. Researchers in the field of psychopharmacology examine how drugs affect the psychological functions of the brain. Scientists in the field of

Integrated Concept Process Model and School-to-Work Research Paper

Integrated Concept Process Model and School-to-Work - Research Paper Example They undertake these activities while being guided by professionals who have both knowledge and experience in education. The role of these professionals is mainly to assist the students to apply the skills they acquire in class in real-life situations. The students can derive from this kind of a scenario several benefits. One of these benefits is that a student can discover the challenges he might encounter in his professional occupation. They can also learn how the skills learnt in class are applied in real-life and the adjustments required in making them suite different situations. Moreover, they can understand the connection between various academic concepts and occupational concepts in their field of study (Erickson, 2002). Previous research indicate that students who move directly from a school-to-work program to employment have better chances of getting good jobs compared to other students (Stull & Sanders, 2003). Therefore, school-to-work curriculum assists a student in acquir ing a better job after graduating. Teaching lesson planning concept to education students The subject of effective instructional teaching is very crucial among all the students aspiring to become professional educators. The subject has several discipline-based concepts one of them being the concept of lesson planning. To teach this kind of concepts effectively, it is essential to develop a method that would be based on the school-to-work curriculum. The method I would use to teach this concept is the use of projects. The students would be expected to design and implement a lesson plan under my supervision or that of any other professional educator. To achieve the best possible result using this method I would design a rubric that would assist the students to understand what is required of them and assist the supervisors in helping students achieve highest standards possible in lesson planning. I expected that the teaching method would benefit my students in several ways. It would en able them to have the ability to effectively design and implement a lesson plan. It would equip them with knowledge on the challenges they might encounter in their career and thus help them prepare accordingly. Using this teaching method to teach the concept of lesson planning would enhance the students understanding of the concept and their ability to apply the concept in their specific area of specialization. According to Anderson (2009), a teaching method is effective only if it enhances students’ learning. The approach of teaching that this teaching method uses could enhance learning among students and therefore it is an effective teaching method. Evaluation of the implementation of the school-to-work curriculum School-to-work curriculum involves programs like youth apprenticeship, high school academies, tech-prep program, occupational academic clusters, and cooperative education (Bailey, 1995). Each of these programs has its own implementation approach in the specific si tuation in which they can be implemented successfully. However, currently all these programs can only be implemented only in the high school and college levels of education. The implementation of these programs also requires dedication of professionals as well as resources. Therefore, the implementation of school-to-work curriculum is a somehow cumbersome and thus requires collaboration of various stakeholders.

Literary analysis of antigone Essay Example | Topics and Well Written Essays - 500 words

Literary analysis of antigone - Essay Example Another theme depicted is the two types of law and justice which are the divine laws and the laws of men. The determination of the characters was also portrayed in Antigone, Creon and Ismene. A social drama was also presented regarding the issues of gender and the law. The issue of mortality is another theme in this trilogy, as shown in the suicides of Antigone, Haemon and Eurydice. Antigone is the daughter of Oedipus and niece of Creon and the fiance of Haemon. She is the protagonist and tragic heroine in this play. Her character exemplifies one of fierce devotion to her family and loyalty to the gods. She buries her brother, Polyneices thereby disobeying Creon’s order. Her hamartia or tragic flaw in her character is her stubborn loyalty to her family and the gods that brings her to her tragic death. Antigone’s character is also a symbol of the feminine revolt. Despite Ismene’s explanation that they are just women and therefore should not go against men, Antigon e still insisted in burying Polyneices. Creon is the king of Thebes and the uncle of Antigone. Creon is the absolute tyrant and the antagonist in the play. He favors the rational laws of man as opposed to the laws of the gods. His hamartia or tragic error is his stubborn allegiance to the laws of man. His hubris or pride is also a flaw in his character.

Approaches to Flat Slab Design

Approaches to Flat Slab Design Abstract This dissertation aims at the flexure behaviour of reinforced concrete flat slabs in the elastic range and at the ultimate load. As such, it endeavours to give readers a thorough knowledge of the fundamentals of slab behaves in flexure. Such a background is essential for a complete and proper understanding of building code requirements and design procedures for flexure behaviour of slabs. The dissertation commences with a general history background and the advantages of using flat slab as the type of floor construction. After that, an introduction of various slabs analysis method as well as the determination of the distribution of moments using elastic theory will be discussed. The building code based methods like ACI direct design method, Simplified coefficient method for BS8110 and EC2 and Equivalent frame method will be explained in details. After that follows a detailed of limit procedures for the ultimate analysis and design of flat slab using general lower bound theory for strip method and upper bound theory for yield line analysis. Besides, the fundamental of the finite element method will be discussed as well. Then, analysis will be carried out on a typical flat slab panel base on each design approach available such as yield line method, simplified coefficient method, direct design method, finite element method as well as Hillerborg strip method. The flexure resistant obtained from the analysis result will then be compared among each others and highlighting the possible pros and cons of the different analysis. Eventually, the analysis results will then be discussed in order to conclude a rational approach to flat slab design and further recommendation will be given to the future improvement of this research. 1. Introduction Concrete is the most widely used construction material in the world compare to steel as concrete is well known as the most versatile and durable construction materials. In fact, concrete is also one of the most consumed substances on Earth after water [1]. Concrete has played a major role in the shaping of our civilization since 7,000 BC, and it can be seen everywhere in our built environment, being used in hospitals, residential buildings, schools, offices, industrial buildings and others [2]. Nowadays, construction should not just be about achieving the cheapest building possible, but providing best value for the client. The best value may be about costs, but also includes speed of construction, robustness, durability, sustainability, spacious environment, etc. In fact, many type of concrete floor construction can easily fulfilled the above requirements. In the past, forming the concrete floor construction into shape was potentially the most costly and labour intensive part of the process. Nowadays, with the help of modern high efficiency modular formwork has speed up the concrete floor construction process. Alternatively, floor slab elements may be factory precast, requiring only assembly, or stitching together with in-situ elements. The result is an economic and swift process, capable of excellent quality and finishes to suit the buildings needs. 1.1 Types of concrete slab construction Concrete slab floor is one of the key structural elements of any building. Concrete floor choice and design can have a surprisingly influential role in the performance of the final structure of the building, and importantly will also influence people using the building. In general, cost alone should not dictate slab floor choice in the construction. However, many issues should be considered when choosing the optimum structural solution and slab floor type that give best value for the construction and operational stages. The optimum slab floor option should inherit benefits such as fabric energy storage, fire resistance and sound insulation between floors and others as achieving these requirements will eventually help the concrete building to lower the operation costs and maintenance requirement in long term. In general, reinforced concrete slab floors can be divided into three categories as detailed below: Flat slab Flat slab is also referred to as beamless slab or flat plate. The slab systems are a subset of two-way slab family, meaning that the system transfer the load path and deforms in two directions. It is an extremely simple structure in concept and construction, consisting of a slab of uniform thickness supported directly by the columns with no intermediate beams, as shown in Figure 1.1. The choice of flat slab as building floor system is usually a matter of the magnitude of the design loading and of the spans. The capacity of the slab is usually restricted by the strength in punching shear at the sections around the columns. Generally, column capitals and drop panels will be used within the flat slab system to avoid shear failure at the column section when larger loads and span are present, as shown in Figure 1.2. Figure 1.1: Solid flat slab Figure 1.2: Solid flat slab with drop panel Flat slab is a highly versatile element widely used in construction due to its capability of providing minimum depth, fast construction and allowing a flexible column grid system. Slabs supported on beams One-way spanning slabs are generally rectangular slabs supported by two beams at the opposite edges and the loads are transferring in one direction only. Figure 1.3 shows the type of one-way slabs. Deep beam and slab Band beam and slab Figure 1.3: Type of one-way slabs However, slab supported on beams on all sides of each panel are generally termed two-way slabs, and a typical floor is shown in Figure 1.4. Figure 1.4: Two-way slab The beams supporting the slabs can generally be wide and flat or narrow and deep beam, depending on the structures requirements. Beams supporting the slabs in one or two way spanning slabs tend to span between columns or walls and can be simply supported or continuous. In this beam-slabs system, it is quite easy to visualize the path from the load point to column as being transferred from slab to beam to column, and from this visualization then to compute realistic moments and shears for design of all members. This form of construction is commonly used for irregular grids and long spans, where flat slabs are unsuitable. It is also good for transferring columns, walls or heavy point loads to columns or walls below. This method is time consuming during the construction stage as formwork tends to be labour intensive [3]. Ribbed and Coffered slabs Ribbed slabs are made up of wide band or deep beams running between columns with equal depth narrow ribs spanning the orthogonal direction. Loads are transferring in one direction and a thin topping slab completes the system, see Figure 1.5. Ribbed with deep beam Ribbed with wide beam Figure 1.5: Types of ribbed slabs Coffered slab may be visualized as a set of crossing joists, set at small spacing relative to the span, which support a thin slab on top. The recesses in the slab usually cast using either removable or expendable forms in order to reduce the weight of the slab and allow the use of a large effective depth without associated with slab self weight. The large depth also helps to stiffer the structure. Coffered slabs are generally used in situations demanding spans larger than perhaps about 10m. Coffered slabs may be designed as either flat slabs or two-way slabs, depending on just which recesses are omitted to give larger solid areas. Figure 1.6 shows the types of waffle slabs. Coffered slab with wide beam Coffered slab without beam Figure 1.6: Type of coffered slabs Ribbed and coffered slabs construction method provides a lighter and stiffer slab, reducing the extent of foundations. They provide a very good form where slab vibration is an issue, such as electronic laboratories and hospitals. On the other hand, ribbed and coffered slabs are very consuming during the construction stage as formwork tends to be labour intensive [3]. 1.2 Flat slab design as the choice of research The choice of type of slab for a particular floor depends on many factors. Cost of construction is one of the important considerations, but this is a qualitative argument until specific cases are discussed. The design loads, serviceability requirements, required spans, and strength requirement are all important. Recently, solid flat slab is getting popular in the construction industry in Europe and UK due to the advantages as below: Faster construction Construction of flat slabs is one of the quickest methods among the other type of floors in construction. The advantages of using flat slab construction are becoming increasingly recognised. Flat slabs without drops (thickened areas of slab around the columns to resist punching shear) can be built faster because formwork is simplified and minimised, and rapid turn-around can be achieved using a combination of early striking and flying systems. The overall speed of construction will then be limited by the rate at which vertical elements can be cast [4]. Reduced services and cladding costs Flat slab construction places no restrictions on the positioning of horizontal services (eg. mechanical and electrical services which mostly running across the ceiling) and partitions and can minimise floor-to-floor heights when there is no requirement for a deep false ceiling. In other words, this helps to lower building height as well as reduced cladding costs and prefabricated services [4]. Flexibility for the occupier Flat slab construction offers considerable flexibility to the occupier who can easily alter internal layouts to accommodate changes in the use of the structure. This flexibility results from the use of a square or near-square grid and the absence of beams, downstands or drops that complicate the routing of services and location of partitions [4]. Undoubtedly, flat slab construction method is getting popular but there are still many different views about what constitutes the best way of reinforcing concrete in order to get the most economic construction. In addition, a range of methods is available for designing the flat slab and analysing them in flexure at ultimate state. Different analysis and design methods can easily result in variety of different reinforcement arrangements within a single slab, with consequent of making the different assumptions in each analysis and design method. Therefore, this research project will concentrate in examining the various analysis methods for the design of flexural reinforcement of reinforce flat slabs in terms of the code provisions, yield line analysis as well as finite element analysis method. 1.3 Research objectives Reinforced concrete slabs are among the most common structural elements, but despite the large number of slabs designed and built, the details of elastic and plastic behaviour of slabs are not always appreciated or properly taken into account especially for flat slab system. This happens at least partially because of the complexities of mathematic when dealing with elastic plate equations, especially for support conditions which realistically approximate those in multi-panel building floor slabs. Because the theoretical analysis of slabs or plates is much less widely known and practiced than is the analysis of elements such as beams, the provisions in building codes generally provide both design criteria and methods of analysis for slabs, whereas only criteria are provided for most other elements. For example, Chapter 13 of the 1995 edition of the American Concrete Institute (ACI) Building Code Requirements for Structural Concrete, one of the most widely used Codes for concrete design, is devoted largely to the determination of moments in slab structure. Once moments, shear, and torques are found, sections are proportioned to resist them using the criteria specified in other sections of the same code [5]. The purpose of this research project is to examine the analysis methods such as Hillerborgs strip, yield line analysis, equivalent frame method, finite element method and etc. particularly for the design flexural reinforcement of reinforced flat slabs, and meanwhile to gain full understanding of the theories. The different analysis methods will then be analysed and compared with the flexural capacity method calculated using general codes of ACI 318 [5], Eurocode 2 [6] and BS8110 [7]. The outcomes of the comparison will lead to highlight the pros and cons of different approaches and codes paving the way to find out a rational approach for the flat slab design in flexure. The main objectives of the proposed research are: To examine the different methods and codes use to handle the flexural capacity of the slab. To outlined the different positive and negative aspect in a specific code or method of design To gain full understanding of the flexural design theories and code requirements. To highlight the most economical design solution to overcome the flexure in a flat slab while maintaining the safety as code requirements. 1.4 Research dissertation methodology The following will be the proposed methodology of the research dissertation: Background of flat slab in construction industry Research of the evolution of flat slabs in the past decades and the major contributions made for the construction industry. Difficulties faced during the flexure design of flat slabs in the past and the possible solution for the problems will be discussed. This part of research process result in closer to the background history and the revolution of flat slab in construction. Overview of flat slab design methods Examine each design approaches used to design for flexure in flat slab such as yield line analysis, Hillerborgs strip method, the simplified coefficient method for BS8110 or Eurocode 2 and direct design method for ACI. An insight into different methods and codes will help to establish and revise the general code provisions and also gain the full understanding of theory and design of flat slab. Analysis of flat slab with different approaches Different analysis and design approaches for flexural reinforcement of RC flat slabs will be performed based on the same model slab. For instance, finite element computer software packages will be used to perform the finite element analysis. This part will eventually provide a deep understanding of various design methods as well as the ability to use finite element software in analysis and design. Research the flexural pros and cons in a flat slab among each design methods to get the rational design approach. Discussion The numerical analysis results obtain from different design methods and the codes will be discussed and compare among each others and also to the experimental results obtain in the previous research papers such as Engineering journals and other relevant engineering sources. This process will ultimately lead to a proper and systematic comparison of the codes and methods used, and highlighting their pros and cons. Conclusion This part will conclude the discussion on advantages and disadvantages of all the examined design methods trying to establish which design method may result in a more economic and rational solution. Furthermore recommendations if required and the possible future areas of research will be brought up. 1.5 Dissertation layout Chapter 2 Overview of Design This section will cover the brief of the evolution of flat slabs history.

ACI, EC2 and BS8110), Hillerborg strip method, yield line analysis Graphs and tables will be available to show the summary of the results from different methods. Chapter 5, Conclusion Summarise the economic and rational flexural design approach for flat slab Further recommendations 2. Overview of Design Method The aim of chapter 2 is to provide an overview of the current practice of the design of reinforced concrete flat slab systems. General code of practice of ACI 318, EC2 and BS 8110 requirements are presented, along with the brief of the ACI direct design method, EC2/BS8110 simplified coefficient method, equivalent frame method, yield line, Hillerborgs strip method as well as finite element method. Each procedure and the limitations are discussed within. The following discussion is limited to flat slab systems. That is, the design methodologies presented below relate only to slabs of constant thickness without drop panels, column capitals, or edge beams. In addition, prestressed concrete is not considered. 2.1 Approaches to the analysis and design of flat slab There are a number of possible approaches to the analysis and design of reinforced concrete flat slab systems. The various approaches available are elastic theory, plastic analysis theory, and modifications to elastic theory and plastic analysis theory as in the codes (eg. ACI Code [5]). All these methods can be used to analyse the flat slab system to determine either the stresses in the slabs and the supporting system or load-carrying capacity. Alternatively, these methods can be used to determine the distribution of moments to allow the reinforcing steel and concrete sections to be designed. 2.1.1 Elastic theory analysis Conventional elastic theory analysis applies to isotropic slabs that are sufficiently thin for shear deformations to be insignificant and sufficiently thick for in-plane forces to be unimportant. The majority floor slabs fall into the range in which conventional elastic theory is applicable. The distribution moments forces found by elastic theory is such that: Satisfied the equilibrium conditions at every point in the slab Compliance with the boundary conditions Stress is proportional to strain; also, bending moments are proportional to curvature The governing equation is a fourth-order partial differential equation in terms of the slab deflection of the slab at general point on the slab, the loading on the slab, and the flexural rigidity of the slab section. This equation is complicated to solve in many realistic cases, when considering the effects of deformations of the supporting system. However, numerous analytical techniques have been developed to obtain the solution. In particular, the use of finite difference or finite element (FE) methods enables elastic theory solutions to be obtained for slab systems with any loading or boundary conditions [8]. Nowadays, with the advancement of computer technology software, designer can easily obtained the bending and torsional moments and shear forces throughout the slab easily with any finite element software packages such as ANSYS, LUSAS, STAAD PRO, SAP2000 and others. 2.1.2 Plastic analysis The plasticity, redistribution of moments and shears away from elastic theory distribution can occur before the ultimate load is reached. This redistribution occur because for typical reinforced concrete section there is little change in moment with curvature once tension steel has reached the yield strength. Therefore, when the most highly stressed sections of slab reach the yield moment they tend to maintain a moment capacity that is close to the flexural strength with further increase in curvature, while yielding of the slab reinforcement spreads to other section of the slab with further increase in load. To determine the load carrying capacity of rigid-plastic members, two principles are used as below: Lower Bound Theorem states that if for any load a stress distribution can be found which both satisfies all equilibrium conditions and nowhere violates yield conditions, then the load cannot cause collapse. The most commonly used approach is Hillerborgs Strip method [9]. Upper Bound Theorem states that if a load is found which corresponds to any assumed collapse mechanism, then the load must be equal to or greater than the true collapse. Finding a load which may be greater than the collapse load may be considered to be an unsafe method; however, because of membrane action in the slab and the strain hardening of the reinforcement after yielding, the actual collapse load tends to be much higher. The commonly used approach of this method is yield line theory [9]. 2.2 Early History and Design Philosophies Credit for inventing the flat slab system is given to C.A.P. Turner for a system describe in the Engineering News in October 1905. However, the first practical flat slabs structure, Johnson-Bovey Building was built in 1906 in Minneapolis, Minnesota, by C.A.P. Turner. It was a completely new form of construction, and in addition there was no acceptable method of analysis available at that time. The structure was built at Turners risk and load-tested before hand in to the owner. The structure met its load test requirements hence the flat slab system was an instant commercial success and many were built in the United States later on [10]. Robert Maillart was also one of the founding fathers of flat slab from Europe, a design-and-built contractor who was perhaps better known for his work on the design of Reinforced Concrete Bridge. In 1908 Malliart carried out a series of full-scale tests on his flat slab system, see Figure 2.1. About the same time, Arthur Lord, a research fellow at the University of Illinois, also became interested in understanding how flat slabs behaved. In 1911, Lord obtained approval to instrument and test load a seven-storey flat slab building in Chicago. The view and work by them paves the way for the development of flat slabs. Their work evolved into a codified method of design and in 1930 became the London Building Act [11]. Then, Robert Malliarts dimensioning method is reviewed and compared with methods of elastic plate theory and plastic analysis. When compared the results with as elastic analysis, Malliart method considerably underestimate the bending moments acting for the flat slabs. However, the comparison made on limit analysis procedures, Malliarts design is still within the reasonable safety margins [12]. Figure 2.1: First test on flat slabs carried out in 1908 at Maillart Co. works in Zurich [11] In 1878, Grashoff have tried to use polynomial approximation deflection function to work out the flat slab design but was unsuccessful to satisfy certain boundary conditions. At that time, concrete flat slab was emerged in the use as boiler cover plates for steam engines. Due to this problem, in 1872, Lavoinne was forced to work out the flat slab using the Fourier series. Lavoinne assumed a uniformely load is loaded on an infinite large plate and the plate is under simply supported conditions. In this assumption, Lavoinne neglected the poissons effect but Grashoff did consider [12]. Maillart was aware of Grashoffs approach but he thought that it was useless for his purpose because it was restricted to uniformly distributed loads and did not account for the stiffening effect of columns. Based on simple equilibrium considerations, Nicholas managed to prove that all these systems resulted insufficient reinforcement [12]. In the year of 1921, Westergaard and Slater managed to develop a new flat slab theory by comparing the theory results to the available experimental results at that time. In the theory, the stiffening effects due to the presence of columns under different load condition were discussed. Marcus had considered this theory later on by applying finite differences approach; Marcus assumed few different boundary conditions and loads. During the past, due to the absence of a proper theory for flat slab design in Germany hence flat slab construction was almost impossible to be carried out. After sometime later, requirements for the flat slab design theory were established. This theory again mentioned that the design moment must follow Lewes theory (1920, 1922) or theory developed by Marcus (1924). [12]. 2.2.1 Robert Maillarts Contribution In 1902, Maillart has successfully developed dimensioning procedure to design a flat slab. This method was used and succeeds in building few numbers of large flat slabs structure. Due to the absence of strict construction rules in Switzerland, Maillart managed to design flat slab by considering the principle of superposition and successfully performed several arbitrary loads testing on flat slabs. Maillart derived the flexure moments at intermediate points by multiplying the flexural stiffness of the slab with the respective curvatures. The curvatures were derived using the double differentiation of the eight-order polynomial functions meanwhile the flexural stiffness of the slab was analysed using simple one way flexure test on respective slab strips [12]. Maillarts reinforcement pattern for flat slab was very close to the current design approaches. Maillarts method required to reinforce the slab in only two directions. However, C.A.P. Turner insisted to reinforce the slab in four directions (see section 2.2.2 for details). Maillart dimensioning procedure emphasised in designing for positive moments at three different locations labeled as O, Q, and C in Figure 2.2 (where O at the midspan, Q at the quarter point of transverse span l2, and C in the column axis). Negative moments were not checked in Maillart dimensioning procedure and all the bottom bars were simply bent up in the columns strips. In this method, the span ratios, size of column capital and the minimum height of the column capital were restricted to certain values, limiting the nominal shear stress at the circumference of the column to a permissible value [12]. Figure 2.2: Robert Maillarts system and notation for plan view [12] Later, Maillarts results were found underestimated with elastic analysis method. In addition, Maillarts method predicts a reduction in average moment value corresponding to span ratio while elastic plate theory remaining constant. Maillarts method underestimated elastic moments especially for a very large slab structure. In other words, Maillarts dimensioning method has significant differences with elastic analysis procedure in the flexure result of slab [12]. Since Maillarts dimensioning method ignored the negative moments hence this worries the designer when came to the safety of the slab design. In conclusion, Maillart underestimated the moments compared to the elastic analysis on the other hand similar approach to the limit analysis [12]. 2.2.2 C.A.P. Turners Concept Turner never published complete details of his design methods in order to maintain a competitive advantage in the design industry. However, some insights of Turners conceptual design of his flat slabs are available in his patent applications (C.A.P. Turner, Steel Skeleton and Concrete Construction and Elasticity, structure and strength of materials used in engineering.) [10]. In fact, Turners principle design was more concerned about shear in flat slabs as stated by him, Beside the unreliability of concrete in tension, it is unreliable in shear in its partially cured condition. This renders desirable use of reinforcement near the columns or supports to take care of shear [10]. In Turners principle, a so called Mushroom heads or cantilever caps were designed to provide shear resistance in flat slabs. As quoted by Turner, heads may be constructed in accordance with the shearing strain. The diameter of cantilever head was about one-half of the span length. Turner presumed the reinforcement cage acted as part of cantilever support to the slab [10]. Figure 2.3 is an example of the cantilever support mentioned by Turner. Figure 2.3: C.A.P. Turner, mushroom or cantilever shear head [10] Besides shear, Turner also focused on moments and used a four way reinforcement which also known as reinforcement belts, see Figure 2.4. These belts have the same width as that of the cantilever shear head. Turner believed that the positive moments were small due to the cantilever support which is stated as, Referring to flat central plate, or the suspended slab portion, there is practically no bending moment at the center [10]. Figure 2.4: C.A.P. Turners four belt floor reinforcement system [10] Also, Turner believed reinforced the slab in four directions (four belt floor reinforcement system) would provide the moment resistance to counter the negative moments at supports. With these conceptions, Turner considered a very small total design moment to proportion the flexural steel in the four belts. Turner simplified the equation as following: (1) where, W = total dead and live load in one bay L = nominal dimensions in one bay As = total flexural steel, distributed among the four belts fs = allowable steel stress d = distance to tension reinforcement Turner used the co-efficient of 1/50 for equation (1) above reference to Grashoff (1878) and to Prof. Henry T. Eddy (1899) from University of Minnesota. In fact, Turner decided to use such a small coefficient due to the consideration of shorter effective span between cantilever heads. Moreover Turner also considered the slab spanning continuously instead of simply supported design. Numerous experiments data performed by Turner proved that such a coefficient was sufficient for flexure resistant. Besides, the use of cantilever head lead to the unnecessary of drop panels in Turners concept. Turners design concept has successfully built many buildings and bridges from year 1905 to 1909 [10]. 2.3 Current Methods of Flat Slab Design 2.3.1 American Concrete Institute (ACI) American Concrete Institute (ACI) is one of the oldest codes and widely been used to design for reinforced concrete structures. The code covers a number of methods to design a flat slab system. The design of structural concrete is dictated by Building Code Requirements for Structural Concrete (ACI 318-05) and Commentary (ACI 318R-05). The ACI code contains procedure for the design of uniformly loaded reinforced concrete flat slab floors. These methods are direct design techniques and equivalent frame method. All these methods are based on analytical studies of the distribution of moments using elastic theory and strength using yield line theory, the results of tests on

Ethnographic Paper :: essays papers

Ethnographic Paper The Pleasure of Pain These days anything can be considered art. The structure of a building, the human body, music on the radio, love, Versaci’s new line of winter, and pretty transvestites walking down the street are just a few of hundreds of thousands of examples. That kind of art is overrated. Most of these only exist because of society. As people grow and change so does the values and traditions that they are accustomed to. True art hangs on the walls of museums all over the world. Paintings by Monet, Da Vinci, and Picasso represent all that can be made beautiful by a man’s touch. The word tattoo comes from the Tahitian word tattau, which means ‘to tap,’ and can be traced back through a part of history. The art of tattoos has been evident since ancient Egypt and more than 1,500 years ago the Japanese marked criminals as a symbol of shame for their punishment (Britannica, 2000). In the nineteenth century tattoos were viewed as frightful and grotesque, but as the twentieth c entury rolled by technology gave way to the trend. The electric needle created a sense of precision and control. This is how the various designs developed and tattooing became more about expression, rather than branding. It is a guarantee that tattoo and piercing artists can be found by the thousands in a metropolitan city. Their form of art may be simpler to an extent, but it has been growing in popularity for years. By using the body as a gateway for expression, people can present themselves in a new light, and as a mean for recreating their image. The concept of transferring art on paper to the body for the mere purpose of self-pleasure is attracting all types of people. It is impossible to walk through a mall without spotting people of all ages with this type of branding. â€Å" Young adults have accepted this practice as a normal part of their culture. You can’t escape it.† Says Walter Hewitt, who recently completed a 19-school study on tattoos and piercing (Vogel, 2000). There are big ones, small ones, tasteful ones, tacky ones, and probably some temporary ones, and because tattooing is forever and also carries a mental heath risk known as regret, the decision to get one shouldn’t be taken lightly. The customer is very vulnerable when entering a tattoo and piercing parlor, because all their trust for a good product is put in the hands of the artist.

Responsible Borrowing Worksheet Essay

Many students borrow federal student loans to pay for college. The goal of this assignment is to help you learn how to borrow responsibly, which may mean that you do not borrow at all or that you borrow only what you truly need. To borrow responsibly, you must understand your options and establish a financial plan for your entire program. With that plan in place, you can then focus on your classes and making connections with instructors and other students. Step 1 Watch the â€Å"Responsible Borrowing (Financial Aid)† video on the orientation website located here: http://www.phoenix.edu/student-orientation.html. Respond to the following questions: What is financial aid? Financial Aid is any grant or scholarship, loan, or paid employment offered to help a student meet his/her college expenses. Such aid is usually provided by various sources such as federal and state agencies, colleges, high schools, foundations, and corporations. How do grants differ from loans? Grants are money you don’t have to repay and are usually based on your financial need while loans are money you borrow that you must pay back, usually with interest costs. The major grants are Cal Grants, federal Pell Grants and some smaller federal grants What effect does class attendance have on funding availability? Students must attend school continuously, with no attendance breaks greater than 14 days, to retain disbursed federal financial aid funds. A leave of absence must be requested and approved if a student requires more than 14 days away from class. Step 2 Navigate to the Personal Finance category of the GEN/127 PhoenixConnect Community. Explore the resources provided and some of the discussions shared by the community members. Respond to the following questions: What did you find about student loan repayment plans? I found out that there are interests rates that cling to the loan and also you should pay close attention to the money you burrow in unsubsidized and subsidized loans because you will have to pay that back and also may sure you keep up with how much your borrowing and the dates that you will have to start repaying, you don’t want them to go into default. Why is having an educational financial plan important? You will need this so you can map out how much needs to be funded for your course and class, its very vital you pay attention to this because you could end up not having enough, thesethings you want to plan out and make sure of so you wont have any bumps or faults along the way. Step 3 Access the Financial Plan at www.phoenix.edu/financialplan. Enter your program and respond to the questions. Explore the information about options for payment, reducing cost, and military students (if applicable). If you have already completed the plan as part of the enrollment process, you can use those results for this step. Based on this plan, what is your estimated monthly payment when you enter repayment? My estimated monthly repayment fee is $56 a month. As a result of completing the plan, what changes can you make to reduce the amount you may borrow? Why? I can check for the cost of the classes so I wont borrow so much, just what I need to pay the cost of each class that way I wont over draw.

Thoreau Our Hero essays

Thoreau Our Hero essays Save the Whales! Protect Wildlife! Save the Rain Forest! Defend our Natural Resources! These would all be sentences frequently heard from Henry David Thoreau in modern America. He would also maintain a career and offside activities. Henry David Thoreau, in modern America, would be an activist and writer; details from Walden and Civil Disobedience shall support his idea. Once a writer always a writer, Thoreau would be a writer in modern America. Thoreau wrote his books in the mid-1800s were typically about natural observation, social criticism, and philosophical insight, these things are very visible today. Thoreau would also participate in several demonstrations either for saving an extinct animal or a component of nature. The book Civil Disobedience shows some evidence to help establish this thought with The objections which have brought against a standing army is only an arm of the standing government. Thoreau would have strongly disagreed with the Alaskan Pipe Line for the reason that it involved superfluous digging on a nature preserve. This is apparent in his book Walden when he says Instead of three meals a day, if it be necessary eat but one... meaning ration the oil. Thoreau would live either in Alaska or Montana in an isolated area far away from a bustling town. He in all probability would live on a ranch or farm. On his land, there would most likely be some type of creek or pond. This is all evident in his book Walden due to the statement, its complete retirement, being about two miles from the village, half a mile from the nearest neighbor, and separated from the highway by a broad field; its bounding on the river... Henry David Thoreau would be a prolific writer, demanding activist and a farming mastermind, and would flourish in modern America. This is all apparent in his books Walden and Civil Disobedience. The Wildlife Lovers Association would adore him. The politicians would...

7 Types of Euphemism

7 Types of Euphemism 7 Types of Euphemism 7 Types of Euphemism By Mark Nichol Euphemisms, words or phrases that substitute for provocative or emotionally charged terms, are employed for various reasons: 1. Abstraction: Some euphemisms serve to distance people from unpleasant or embarrassing truths, as when we say that a dead person passed away or a celebrity who has canceled an appearance is suffering from exhaustion. 2. Indirection: A euphemism may replace an explicit description of an action, as when people speak of going to the bathroom or of others sleeping together. 3. Litotes: Sometimes, euphemism occurs in the form of this rhetorical device in which the gravity or force of an idea is softened or minimized by a double negative, as in the reference to someone as being not unattractive. 4. Mispronunciation: Alteration of pronunciation is a form of euphemism, as when we say frigging or shoot, or jeez or cripes, so as not to offend people by using profanity (figurative or literal). These types of euphemisms, involving rhyme, alliteration, or shortening, are also called minced oaths. 5. Modification: A bluntly offensive noun can be transformed into a euphemism by converting it to an adjective, as in saying someone has socialist leanings rather than labeling them a socialist outright. 6. Personification: One form of euphemism is when things that some people prefer not to mention candidly, such as genitals, are assigned personal names. (I will go beyond euphemism and let readers think of examples on their own.) 7. Slang: Much of slang, derived to produce a vocabulary exclusive to a social group, is euphemism, as in the use of joint for marijuana (itself a slang term, derived from the Spanish names Mary and Juana closely related to â€Å"Mary Jane,† yet another euphemism). Corporations and government bureaucracies, including military services, are masters are creating euphemisms of abstraction and indirection such as pre-owned for used, effluent for pollution, and â€Å"collateral damage† in place of â€Å"accidental killing.† Euphemism is also often employed in an attempt to make polite reference to physical or psychological disability, though some people argue that while a trend toward ever more euphemistic language seems to accord people so labeled more respect, euphemism can also diminish the public perception of the seriousness of the condition. Not all euphemism is deplorable, but much of it is, and writers and editors must search their consciences and uphold their principles in deciding whether to couch terms or whether to use straightforward language. Although an increased likelihood of euphemism seems to correlate with the extent of distribution of a publication, it is also often true that the more widespread the readership of a publication, the safer it is for those who produce its content to be blunt and honest.

Crisis Management Paper Essay Example | Topics and Well Written Essays - 1750 words

Crisis Management Paper - Essay Example An important question faced by governments and democracies is whether this change from crisis management as the politics of exception to crisis management as part of regular politics may require different political arrangements: in the relation between the executive and legislative branches of government, for example, and regarding questions such as whether more stringent policy coordination is required, whether we need better communication and interaction with the public, and whether we need different modes of intergovernmental cooperation. The particular policies defining staff duties in hotels will vary somewhat, as will the moral orientations of the supervisors, and the nature of the clientele and "intruders" encountered, but from the security officer's perspective, keeping order is characterized by two major elements. The first and most apparent responsibility is that of "protecting hotel guests, staff, and property from theft or other abuse." Secondly, the security officer is expected to operate in a "public relations capacity;" to help make the guests' stays pleasant and to maintain a respectable image of the hotel. While much more important than might first seem, this second concern has profound implications for the management of trouble. It places limitations on the ways in which security officers may respond to troublesome persons, suggesting that deviance be handled informally and as unobtrusively as possible. Perceiving hotel security to be disadvantaged relative to the authority of peace officers and more r esponsible for public relations, security people (and their employers) place considerable emphasis on abilities to handle incidents with a minimum of physical force. Keeping a Clear Lobby: the lobby areas of hotels can represent difficult places in which to keep order. Thus, in addition to the possible confusions which may result from guests (and their children) checking in and out of the hotel with baggage and other belongings, security officers frequently have unwelcome entrants such as drunks and vagrants, hookers and hustlers, and other loiterers Dealing with Room Trouble: Trouble in the rooms involves the guests in some respect, but the knowledge that trouble is taking place in these locations is of limited value in predicting its form. Thus, while noise, drug use, theft, and vandalism are among the more common sources of trouble, guests may also call security in matters pertaining to physical violence, accidents, sicknesses, and misplaced items. The staff should be hired to keep a note on things in the rooms as the customer prepares to leave, further there should be clear notice inside the room regarding things not to do. Hijacking The pilot is the prime player in the hijack situation because he controls the aircraft and the crew. The first concern the pilot has, after ensuring the safety of his passengers, crew, and aircraft, is to advise the ground authorities that he has been hijacked.

Nursing and Human Resource Sector of the Health Care Industry Assignment

Nursing and Human Resource Sector of the Health Care Industry - Assignment Example The present research has identified that there is a rising cost of providing healthcare to over 230,000 individuals, a task that is making hard for the health care system to retain and attract employers who are discouraged by the premium costs. The employers are facing the effect of having to reduce or absolutely not offering any health care benefits to the employees. The Mercy Health plans are also finding it very difficult to get a local health plan for the employers. There is also the issue of competitors who offer national health plans and worse, they have a large share of the market. As such, the mercy health plan has to strategize themselves so as to face the existing competition in the market. Among the solutions considered by the Mercy Health Plans in the face of the problem of attracting employers into their health plans, they have decided to attract employers through offering them more attractive health plans that apply to the long-term relationship they have with their emp loyee. They encourage the senior management teams of the employers to take up their health plans in order to solve this problem. This is in opposition to the selection of short-term health care plans by the senior management. This is because the short-term health plans tend to be a source of cost shifting solution to the employer and mostly offered by consumer-directed programs for health benefits. Further, the mercy health plan realizes that they have to design a health program that would cover the overall health of the entire population. This includes the consumers that do not have a high risk of healthcare complications and their probabilities of getting sick is also low. As such, it is possible that the Mercy Health plan can reduce the cost of health and attract more employers.
