Free Essays on Multicultural Education

Multicultural Education We are in search of the true America- an America of multiple cultures, multiple histories, multiple regions, multiple realities, multiple identities, multiple ways of living, surviving and being human. And no where is this struggle for the true America more profoundly being waged than in the classrooms of public schools in the United States. –Darder (Sleeter, 1995 p. 5) Through this quote Darder sums up the reason for multicultural education; America consists of people of multiple characteristics and through multicultural education these differences can be found, understood and celebrated. Multicultural education is the key tool in educating youth today; with the goals behind it and the effects it will have on people, multicultural education is the foundation of a better society. Multicultural education â€Å"affirms that schools should be oriented toward the cultural enrichment of all children and youth through programs†¦[that] preserve and extend†¦ cultural alternatives†; it should â€Å"recognize cultural diversity† and its value as a resource (Baptiste, 1979 p. 16). Schools that practice multicultural education use different programs and curriculum to teach different aspects of cultures by integrating them into everyday studies. This kind of education is used to make students realize the importance and worth of diversity. A major emphasis in the definition of multicultural education is â€Å"cultural pluralism† –the resistance of the melting pot theory (Bennett, 1999 p. 11). Through cultural pluralism a person has the right to express their individuality and in turn respects the rights of and appreciates people of a different culture. Multicultural education contradicts the â€Å"historic American goals of assimi lation and integration of ethnic cultures into the majority culture† (Wilson, 1997).

The Management of The Hotel Olympia Essay Example | Topics and Well Written Essays - 1750 words

The Management of The Hotel Olympia - Essay Example It is evidently clear from the discussion that the management in the hotel will improve on the existing accounting systems as well as be coming up with a work breakdown structure (WBS) in order to define the employees discrete work elements in such a way that it will help organize as well as define the total work scope of the project. The management as part of the project will also apply the top-down strategic planning to ensure that the hotel can compete effectively in the global market. The hotels back office accounting systems had been computerized years ago for the effective functioning of the business and this needs a number of improvements. The front desk functions like the reservations check in and check outs are a mixture of word processor template to produce bills as well as spreadsheets for room bookings and they are usually printed manually every day. The management, therefore, feels important to integrate more systems to avoid manual work and increase efficiency. When ord ering food from the restaurant and drinks from the bar and restaurant, it becomes quite unreliable. With advanced knowledge of bookings would try to ease ordering and booking and with a computerized ordering system which would allow stocks of food to be minimized would reduce food wastage and allow for considerable savings. The Olympia games will be held in the region in three months time and we should take advantage of this great opportunity to expand the ordering and bookings systems since most of the customers would like to book for our services online. The hotel will triple its residency for the period of the games and for several months afterward. Extensive marketing will also be done and the following include the marketing strategies the management will apply.

Reflection of chapter themes in the book Why Evolution is True by Term Paper

Reflection of chapter themes in the book Why Evolution is True by Jerry A Coyne - Term Paper Example Lastly, the scientific concept of evolution shall be criticized based on a personal opinion. Evolution has been defined as the gradual genetic change that the species usually undergo due to the environmental pressures. The DNA, a vital element of the animal cell, has taken all the living creatures to a single common ancestor. Most animals share the patterns of their DNA. This was before the evolution took place. The evolution eventually took place and the organisms have been biologically and geographically separated from each other. Evolution took place in three different forms. These are: Gradualism, Speciation and the Natural selection. In gradualism, the species take several generations to attain the desired change that will enhance their survival. Thus, evolution takes many years to be fully achieved. Speciation is the process whereby organisms split into different species. It is the evolution of different species that cannot easily interbreed. Natural selection, according to Coyne, is just but a ‘tinkerer’. This means that natural selection does not yield any original perfection in a species but, only improves on what ha s already been established. In this chapter, a number of theories have been brought forward. They included the evolution theory, cell theory, plate tectonic theory and atomic theory. However, the book specifically concentrates on the evolution, which, argues that all living organisms originated from a common ancestor. Chapter Two concentrates on the Fossils as evidence of evolution. Fossils are the remnants of the ancient species that resemble the living animals of today. The fossils have always been there since the beginning of time; even Darwin and Aristotle discussed fossils in their books. Fossil formation takes a few but very lengthy steps. First, there must be remains of either animals or plants. These remains must sink in deep waters for quite a long time. However, the sunken remains must be

What Is Power Electronics Engineering Essay

What Is Power Electronics Engineering Essay Power electronics involves the study of electronic circuits intended to control the flow of electrical energy. These circuits handle power flow at levels much higher than the individual device ratings. It has been said that people do not use electricity, but rather they use communication, light, mechanical work, entertainment, and all the tangible benefits of both energy and electronics. In this sense, electrical engineering is a discipline very much involved in energy conversion and information. In the general world of electronics engineering, the circuits engineers design and use are intended to convert information, with energy merely a secondary consideration in most cases. This is true of both analog and digital circuit design. In radio frequency applications, energy and information are sometimes on a more equal footing, but the main function of any circuit is that of information transfer. What about the conversion and control of electrical energy itself? Electrical energy sources are varied and of many types. It is natural, then, to consider how electronic circuits and systems can be applied to the challenges of energy conversion and management. This is the framework of power electronics, a discipline that is defined in terms of electrical energy conversion, applications, and electronic devices. More specifically, Rectifiers are probably the most familiar example of circuits that meet this definition. Inverters (a general term for dc-ac converters) and dc-dc converters for power supplies are also common applications. As shown in Fig. 1.1, power electronics represents a median point at which the topics of energy systems, electronics, and control converge and combine [1].Any useful circuit design for the control of power must address issues of both devices and control, as well as of the energy itself. Among the unique aspects of power electronics are its emphasis on lar ge semiconductor devices, the application of magnetic devices for energy storage, and special control methods that must be applied to nonlinear systems. In any study of electrical engineering, power electronics must be placed on a level with digital, analog, and radio-frequency electronics if we are to reflect its distinctive design methods and unique challenges. FIGURE 1.1 Control, energy, and power electronics are interrelated. All power electronic circuits manage the flow of electrical energy between some sort of source and a load. The parts in a circuit must direct electrical flows, not impede them. A general power conversion system is shown in Fig. 1.2. The function of the power converter positioned at the middle is that of controlling energy flow between a given electrical source and a given load. For our purposes, the power converter will be implemented with a power electronic circuit. As a power converter appears between a source and a load, any energy used within the converter is lost to the overall system. A crucial point emergesà ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬to build a power converter, we should consider only lossless components. A realistic converter design must approach 100% efficiency. A power converter connected between a source and a load also affects system reliability. FIGURE 1.2 General systems for electric power conversion A circuit built from ideal switches will be lossless. As a result, switches are the main components of power converters, and many people equate power electronics with the study of switching power converters. Magnetic transformers and lossless storage elements such as capacitors and inductors are also valid candidates for use in power converters. The complete concept, shown in Fig. 1.3, illustrates a power electronic system. Such a system consists of an energy source, an electrical load, a power electronic circuit, and control functions. The power electronic circuit contains switches, lossless energy storage elements, and magnetic transformers. The controls take information from the source, load, and designer and then determine how the switches operate to achieve the desired conversion. The controls are usually built up with conventional low-power analog and digital electronics. FIGURE 1.3 a basic power electronic system Trends in Power Supplies : As costs of electronics decline, the power supply becomes a larger fraction of system cost and design effort. One major manufacturer estimates that power supply cost will soon reach 50% of the total cost of a typical electronic product such as a cordless telephone or personal computer. Thus, new technology developments in power supplies are critically important. In the past, bulky linear power supplies were designed with transformers and rectifiers from the ac line frequency to provide low-level dc voltages for electronic circuits. Late in the 1960s, use of dc sources in aerospace applications led to the development of power electronic dc-dc conversion circuits for power supplies. In a typical power electronics arrangement today, an ac source from a wall outlet is rectified without any transformation; the resulting high dc voltage is converted through a dc-dc circuit to the 5V, 12 V, or other level required. These switched-mode power supplies are rapidly supplanting linear supplies across the full spectrum of circuit applications. A personal computer commonly requires three different 5V supplies, two .12 V supplies, a ÃÆ' ¿12 V supply, a 24 V supply, and perhaps a few more. This does not include supplies for 1 Introduction 3 video display or peripheral devices. Only a switched-mode supply can support such complex requirements without high costs. The bulk and weight of linear supplies make them infeasible for hand-held communication devices, calculators, notebook computers, and similar equipment. Switched-mode supplies often take advantage of MOSFET semiconductor technology. Trends toward high reliability, low cost, and miniaturization have reached the point at which a 5 V power supply sold today might last 1,000,000 hr (more than 100 yr), provide 100Wof output in a package with volume This type of supply brings an interesting dilemma: the ac line cord to plug it in actually takes up more space than the power supply itself. Innovative concepts such as integrating a power supply within a connection cable will be used in the future. Device technology for power supplies is being driven by expanding needs in the automotive and telecommunications industries as well as in markets for portable equipment. The automotive industry is making a transition to 42 V systems to handle increasing electric power needs. Power conversion for this industry must be cost effective, yet rugged enough to survive the high vibration and wide temperature range to which a passenger car is exposed. Global communication is possible only when sophisticated equipment can be used almost anywhere. This brings a special challenge, because electrical supplies are neither reliable nor consistent throughout much of the world. While in North America voltage swings in the domestic ac supply are often Given the enormous size of worldwide markets for telephones and consumer electronics, there is a clear need for flexible-source equipment. Designers are challenged to obtain maximum performance from small batteries, and to create equipment with minimal energy requirements. DEVICE TYPE CHARACTERISTICS OF POWER DEVICES Diode: Current ratings from 5000 A. Voltage ratings from 10V to 10 kV or more. The fastest power devices switch in BJT (Bipolar Junction Transistor): Conducts collector current (in one direction) when sufficient base current is applied. Power device current ratings from 0.5 to 500 A or more; voltages from 30 to 1200V. Switching times from 0.5 to 100 ms. The function applies to dc-dc circuits; combinations with diodes are used in inverters. Power BJTs are being supplanted by FETs and IGBTs. FET (Field Effect Transistor): Conducts drain current when sufficient gate voltage is applied. Power FETs (nearly always enhancement mode MOSFETs) have a parallel connected reverse diode by virtue of their construction. Ratings from _1 to _100 A and 30 up to 1000V. Switching times are fast, from 50 or less up to 200 ns. The function applies to dc-dc conversion, where the FET is in wide use, and to inverters. IGBT (Insulated Gate Bipolar Transistor): A special type of power FET that has the function of a BJT with its base driven by a FET. Faster than a BJT of similar ratings, and easy to use. Ratings from 10 to >600 A, with voltages of 600 to 1700V. The IGBT is popular in inverters from _1 to 100kW or more. It is found almost exclusively in power electronics applications. SCR (Silicon Controlled Rectifier): A thyristor that conducts like a diode after a gate pulse is applied. Turns off only when current becomes zero. Prevents current flow until a pulse appears. Ratings from 10 up to more than 5000 A, and from 200V up to 6 kV. Switching requires 1 to 200 ms. widely used for controlled rectifiers. The SCR is found almost exclusively in power electronics applications, and is the most common member of the thyristor family. GTO (Gate Turn-Off Thyristor): an SCR that can be turned off by sending a negative pulse to its gate terminal. Can substitute for BJTs in applications where power ratings must be very high. The ratings approach those of SCRs, and the speeds are similar as well. Used in inverters rated >100 kW. TRIAC: A semiconductor constructed to resemble two SCRs connected in reverse parallel. Ratings from 2 to 50 A and 200 to 800V. Used in lamp dimmers, home appliances, and hand tools. Not as rugged as many other device types, but very convenient for many ac applications. MCT (MOSFET Controlled Thyristor): A special type of SCR that has the function of a GTO with its gate driven from a FET. Much faster than conventional GTOs, and easier to use. These devices are supplanting GTOs in some application areas. POWER CONVERTERS The power processors usually consist of more than one power conversion stage where the operation of these stages is decoupled on an instantaneous basis by means of energy storage elements such as capacitors and inductors. Therefore, the instantaneous power input does not have to equal the instantaneous power output. We will refer to each power conversion stage as a converter. Thus, a converter is a basic module (building block) of power electronic systems. It utilizes power semiconductor devices controlled by signal electronics (integrated circuits) and possibly energy storage elements such as inductors and capacitors. Based on the form (frequency) on the two sides, converters can be divided into the following broad categories: 1. AC to DC 2. DC to AC 3. DC to DC 4. AC to AC We will use converter as a generic tenn to refer to a single power conversion stage that may perform any of the functions listed above. To be more specific, in ac-to-dc and dc-to-ac conversion, rectifier refers to a converter when the average power flow is from the ac to the dc side. Inverter refers to the converter when the average power flow is from the dc to the ac side. In fact, the power flow through the converter may be reversible. Power Electronic Applications (a) Residential Refrigeration and freezers Space heating Air conditioning Cooking Lighting Electronics (personal computers, other entertainment equipment) (b) Commercial Heating. ventilating, and air conditioning Central refrigeration Lighting Computers and office equipment Uninterruptible power supplies (UPSs) Elevators (c) Industrial Pumps Compressors Blowers and fans Machine tools (robots) Arc furnaces, induction furnaces Lighting Industrial lasers Induction heating Welding (d) Transportation Traction control of electric vehicles Battery chargers for electric vehicles Electric locomotives Street cars, trolley buses Subways Automotive electronics including engine controls (e) Utility systems High-voltage dc transmission (HVOC) Static var compensation (SVC) Supplemental energy sources (wind, photovoltaic), fuel cells Energy storage systems Induced-draft fans and boiler feed water pumps (f) Aerospace Space shuttle power supply systems Satellite power systems Aircraft power systems (g) Telecommunications Battery chargers Power supplies (dc and UPS)

Production and the Workforce Essay

Corporate culture and the potential of ethical and legal issues should be of concern to a job candidate because, after all, the applicant is striving to be a part of that organization; therefore those matters of importance which might affect how the applicant is treated once he is hired should be of foremost importance for the candidate to know. It can help the applicant to avoid making unwise employment decisions (Gibson, 2002), as well as aid in the actual interview process, by having the knowledge of the right things to say and when to say it. These issues should also concern current employees, as being already inside the confines of the organization, they will be the persons most affected by the culture and the ethical and legal issues which may arise while they are employed by the company. For instance, a potential legal issue about compensation should already be known by employees so that they may do something about the matter, otherwise, they will be the ones to suffer about unresolved concerns, particularly the subject about remuneration. Managers, above all, should be highly familiar with the corporate culture and the potential of ethical and legal issues within his/her authority, as they will be looked up to by subordinates to facilitate the inculcation of the culture to all members of the organization as well as deal with ethical and legal issues which may arise concerning employees under his/her control. The community where the business operates should also somehow be concerned with the culture and the potential issues of the organization, as they are stakeholders, as well, in where such an issue as corporate social responsibility falling under ethical and legal matters would directly affect the community because how the business carries on with its activity is sure to reverberate effects to the community, whether this particular group likes it or not. Different aspects of the corporate culture and potential ethical and legal issues are typically of more importance to the various stakeholders, depending on what they are concerned of. Where internal stakeholders are found to be more concerned about culture, external stakeholders are likely to focus on ethical and legal issues concerning them.
