To Kill a Mockingbird Essay Example for Free

To Kill a Mockingbird Essay Thru ought the story To Kill a Mockingbird there are lots of important characters. But there is one specific family everyone is curious about; the Radley family. There were only four inhabitants of their household Mr. and Mrs. Radley, Boo, and Nathan Radley. Everyone wondered what they would do in their house? Mrs. Radley only came out to sweep the porch, Nathan only came out to get groceries and to help when Miss Maudie’s house was burning down, and Boo only comes out when he supposedly give Scout the blanket when Miss Maudie’s house is burning down and at the end when the most significant part when he comes out and help Scout and Jem escape from Mr. Ewell. But like Atticus said, â€Å"you never really know a person until you consider things from his point of view . . . until you climb into his skin and walk around in it. † The Radley house was described as â€Å"The remains of a picket drunkenly guarded the front yard-a â€Å"swept† yard that was never swept-where Johnson grass and rabbit-tobacco grew in abundance. † (Page 8) This is what I pictured the house to look like but with more trees and weed blocking the place because Boo never came out. Nathan only came back to live with his family so he can take care of his sick mom. Mr. Radley only came out to get groceries. And Mrs. Radley only came out for a mid-morning coffee break with her neighbors. They weren’t religious in anyway, you could never find them at church or in a missionary circle. Mr. Radley to my imagination and character analysis was pictured as protective. My favorite quotation that both describe Mr. and Mrs. Radley is the one where Dolphus Raymond speaks to Scout and Dill outside the courtroom. He says, â€Å"I try to give ‘em a reason, you see. It helps folks if they can latch onto a reason. . . He can’t help himself, that’s why he lives the way he does. † (Page 200) This quote describes the Radley parents so well to me because in the beginning of the book the narrator, Scout, talks about how Arthur Radley at once became friends and started causing raucous around Maycomb County. Eventually, they Cunningham boys and Arthur got into some trouble and had to go to jail. Arthur’s dad was there to back him up all the way, he had bailed him out of jail and begged the judge to let him go promising him that his son wouldn’t cause anymore trouble. So, after that the Radleys’ stayed inside a whole lot except to get the necessities they needed and this quote reminded me of the Radleys’ because they maybe just gave people a reason to think they stayed inside was because of their son. Maybe it wasn’t really because of that.

Causes of the French Revolution Essay Example for Free

Causes of the French Revolution Essay The French Revolution of 1789 consisted of many aspects which led to the movement. Both long-term and immediate causes bequeathed to its triumph. The Enlightenment bestowed a new concept of government and society. America also influenced the nation’s controversial revolt. Many actions contributed to the French Revolution of 1789; according to an excerpt from Travels in France by Arthur Young. (Document 1) Observations made by this traveler from the years 1787 to 1789 encompass the immense taxing on those who were not nobles, the increased price of bread; making the peoples’ purchase of the resource inevitable and the insane prices of feudal dues. According to Document 2, a diagram of the three estates in 1789, the relationship between the percentage of the population in each estate and the percentage of the land owned showed that the larger the population the more the land owned on the estate; primarily focused toward the third estate. Inequitable circumstances subsisted in pre-revolutionary France, entailing the third estate facing much more of the taxes and fees than the other estates. In Document 3, excerpts from the cahiers listed the following demands made by the third estate in the French government: reform of abuse and tyranny, equal taxation amongst all classes, taxes granted for a limited period, and votes taken per person within assembly. Another cause of the French Revolution of 1789 as expressed by Lord Acton was due to the American influence. He suggested that the ideas of philosophers were not the cause of the epidemic, but that it was the contemplation provided by the Declaration of Independence. (Document 5) The following actions contributed to the success of the French movement. Each cause led to the uproar of the third estate that caused them to revolt. The documents mentioned above are verification of the involved causes. The causes led to an ambitious fight for rights resulted in what we know as the French Revolution of 1789.

Human Comfort And Thermal Comfort Engineering Essay

Human Comfort And Thermal Comfort Engineering Essay Abstract: The main purpose of the HVAC system is to achieve clean indoor air quality and human comfort (thermal comfort), there are many HVAC systems a designer or owner has the option to select based on the factors such as the type of the building, architecture, location, shape, surrounding climate, occupancy, envelop, level and frequency of activities, and the system operation schedule. In addition to the above base factors that an HVAC system is expected to be selected upon, the energy consumption, system efficiency, initial and operational cost, and finally, feasibility (short and long term rebound positive effect) are of the owners and designers critical concerns. This paper will discuss the elements of a typical feasible high performance low cost, fine tuned HVAC DDC integrated system to achieve the best for users, owners, and environment. 1. Introduction HVAC and its associated auxiliaries system are major energy consumers in a building, the rapid development of the advanced technology nowadays boosts the HVAC system feasibility as more complex control systems are developed for this industry and additional fine-tune, prompt response, standardized communication, ease of control and monitor, and remote accessibility. The BMS/DDC (Building Management System/ Direct Digital Control) integrated system is the core of a good feasible high-efficient HVAC system. The BMS is the most recent High-Tech energy management system that manage a building performance to the maximum desirable pre-determined set of parameters which able to control, monitor, adjust, save and record mostly all of the building facilities and utilities when integrated with all of the compatible buildings Sub-LANs, a DDC is one of those LANs and can communicate with other control LANs under the supervision of the BMS. BMS is able to supervise, control, adjust and record the illumination, electric power control, HVAC, security and observation, magnetic card and access, fire alarm, lifts, and other engineering systems. Integrated with the BMS, the DDC performs the HVAC control management and communicates with the other building controllers via the BMS to achieve integration based on a specified, programmed event sequence. I The DDC is the heart of an efficient HVAC system, it finely tunes the digital/analog input/output communication between sensors, probes, stand-alone controllers, LANs controllers, and finally the controlled element which could be an actuator that adjust the process variable (flow, temperature, level, or pressure), and allows for a feedback signal to further adjust the desired process set-point. This whole process is reported in a real-time manner to the BMS system for further coordination with the other buildings controllable systems to achieve integration based on the pre-programmed parameters. In order to achieve the highest human comfort, energy saving, and a long term rebound effect strategy, The BMS/DDC system should be interlocked and integrated with a high-efficient and feasible HVAC system, this combination can awards energy saving, system and environment sustainability, human comfort, and business feasibility. An Optimal Air System is a good example of a low-coast, high-performance, energy-efficient and a good investment for long-term rebound pay-back effect. Optimal Air System concept is based on the low temperature supply system that needs, less energy consumption by the most energy consumer auxiliary that is the fan, this affects the sizing of the ducts (less duck size), air handling units and fan motors, all of which will be smaller and results in a system that requires less space and uses less power. As this paper focuses on the HVAC/DDC integrated system application for human comfort, energy saving, and feasibility (long-term rebound effect), I will discuss and focus on the DDC and Optimal Air System integration for the above purposes and define characteristics, elements, and functions of both systems. II 2. DDC DDC has became the latest and the most recently used system for HVAC controls after the pneumatic and electromechanical control systems, digital pre-programmable controllers can handle extensive digital/analog data process from inputs (sensors, tranceducers and transmitters) that tyapically mesure temperature, flow, humidity, pressure or level, and outputs to final controlled devices to adjust a process variable based on a preset parameters, also recives a feedback signals from inputs again to further adjust signal command errors for best results based again on the setpoints. Digital inputs are Dry contacts from a control device, analog inputs are voltage and current signals that mesure variables such as humidity, pressure, level or flow form sensing devices and converted to percentage. Digital outputs are of 1 or 0 binary that either stops or starts equipments via a relay, analog outputs are voltage or current signals that control a process variable control devices such as valves, m otors or dampers. The DDC program code may be customized for intended use such as: Time schedule, sequence of operation, trend logs, alarms. 2.1 Elements of a DDC As described above, the three functional elements needed to perform the functions of a DDC system are: a) A measurement element (Sensor, prob, Transmitter, Transducer) b) An error detection element (Digital/Analog/pneumatic Controller, PCU) c) A final control element (Motor/Piston Actuator, VFD, VSD, Relay) 2.2 DDC controled mediums The DDC controls two variables: I. A controlled variable is the process variable that is maintained at a specified value or within a specified range. II. A manipulated variable is the process that is acted on by the control system to maintain the controlled variable at the specified value or within the specified range. 1 2.3 Functions of DDC system In any DDC, the four basic functions that occur are: a) Measurement b) Comparison c) Computation d) Correction 3. DDC LAN-WAN Configuration DDC is where mechanical and electrical systems and equipment are joined with microprocessors that communicate with each other and to a central computer BMS. This computer and controllers in the building Management system can be networked to the internet or serve as a stand alone system for the local peer-to-peer controller network only Fig 1. Additionally, the controllers themselves do not need a computer to operate efficiently as many of these controllers are designed to operate as stand-alone controllers and control the specific equipment they are assigned to control. Fig 1. Typical peer-to-peer controller network [1] 2 With a few exceptions, each DDC or building automation controller holds their own programs and has the ability to communicate to other DDC building automation controllers. It is important for the DDC or building automation controllers to communicate to each other. If the network fails for whatever reason then the system may still function (because the DDC controllers in a BMS system are stand-alone) but it will not function as efficiently as designed. The DDC/BMS system can be configured as independent (localized) closed-system, or DDC open-system based on accessibility options required by a group of buildings managed by a single company or property management firm (centralized), or a single property to be monitored and controlled by its own (localized) Fig 2. Fig 2. DDC/BMS LAN/WAN configuration [2] 3 3.1 BACnet compatibility BACnet is the term commonly used to refer to the ANSI/ASHRAE Standard 135- 1995, adopted and supported by the American National Standards Institute (ANSI) and the American Society of Heating Refrigeration and Air-Conditioning Engineers (ASHRAE). BACnet stands for Building Automation and Control network. BACnet is a true, non-proprietary open protocol communication standard conceived by a consortium of building management, system users and manufacturers [3]. A closed protocol is a proprietary protocol used by a specific equipment manufacturer. An open protocol system uses a protocol available to anyone, but not published by a standards organization. A standard protocol system uses a protocol available to anyone. It is created by a standards organization. Open Systems: An open system is defined as a system that allows components from different manufacturers to co-exist on the same network. These components would not need a gateway to communicate with one another and would not require a manufacturer specific workstation to visualize data. This would allow more than one vendors product to meet a specific application requirement. The DDC/BMS BACnet based LANs and Sub-LANs can be accessed, controlled and monitored from remote locations via the Internet trough a centralized data management system which is capable of collecting data from multiple sites. This is accomplished by connecting with a gateway for collecting data from the lighting and air-conditioning control systems installed in each building or factory, and the center server for providing data collection, database and web server functions along with security measures applied to all transmitted data. Based on the capability of real-time monitoring and analysis of actual energy consumption such as electricity and gas from a remote location by using a web browser, this system is able to achieve the maximum level of energy saving in buildings and factories which in turn, reduce the emissions and the environmental impacts by taking advantage of its cost effectiveness and by limiting the required energy for a specific application or function. 4 Fig 3, Integrated BACnet based WEB Browser BMS Control System Layout [4] 5 4. DDC/BMS integrated features, application and functions 4.1 Energy saving DDC/BMS allows the owner to set up schedules of operation for the equipment and lighting systems so that energy savings can be realized when the building or spaces in the building are unoccupied. Have algorithms as reset schedules for heating plants, static pressure control, and other systems where energy savings can be realized through these predictive programs. 4.2 Human comfort (thermal Comfort) DDC/BMS system allows the equipment optimal start with pre-scheduled program. Optimal start is allowing the equipment to be brought on in an ordered and sequential manner automatically on a schedule before the building is reoccupied so that space set points can be realized before occupation. Event sequence programming features allow the system to compare space temperature, outside air conditions, and equipment capabilities so that the equipment can be turned on at an appropriate time to ensure space set points are achieved before occupation. Have trim and respond capabilities. Based on zone demand the set point for various heating and cooling sources will change according to demand from the zones. For instance, in a Variable Air Volume system, all the VAV boxes are served from a central air handling unit. If all the zones are at set point then the supply air temperature set point of the air handler is automatically changed to prevent mechanical cooling from occurring when it is unnecessary. When the zones grow warmer the supply air temperature set point is automatically lowered to allow mechanical cooling to satisfy demand. In conjunction with the appropriate mechanical system set-up, offer economizing based on enthalpy calculations and/or CO2 set point control. 4.3 Long-term rebound effects Offer load shedding when power companies are at peak demand and need business and industry to cut-back on power usage to prevent black outs. Building Management systems for instance, allow the owner to cycle various things off like water heaters or drinking fountains where use of these things- 6 -will not be noticed even though they are off. Management companies who acquire a good DDC/BMS can set up the system to bill tenants for energy usage (fewer employees required). 4.4 Proactive Ability to send alarms via email, pager, or telephone to alert building managers and/or technicians of the developing problems, and system failures. 4.5 Other applications and compatibilities Have the ability to monitor energy usage including the ability to meter electric, gas, water, steam, hot water, chilled water, and fuel oil services. Have the communications abilities to be integrated with other buildings via WAN setup using the standardized TCP/IP family of protocols. It is BACnet base web browser compatible and other open source communication protocol which allows the system to be accessed via the web browser from remote locations. (Refer to 4.2) 5. High-performance Low-energy HVAC design Recall the Introduction, In addition to BMS/DDC System application for energy saving and high HVAC system performance, a green HVAC system design will achieve all aspects of comfort, energy saving, low initial and operational capital costs, and adds more efficient performance in conjunction with the DDC system, an example of such green HVAC system would be an Optimal Air System [5]. Optimal Air System concept, idea and example are taken from McQuay Air Conditionning/2002 McQuay International/Application Guide AG 31-005 as an example to illustrate its benefits for energy saving, human comfort, lower initial cost and long term rebound effects. Optimal Air systems uses less energy than conventional systems on an annual basis, for example, In a conventional system, supply air temperatures run between 54Â °F -57Â °F from the air handling unit. With duct heat gain, the supply air ranges from approximately 56Â °F-59Â °F out of the air diffuser. 7 In Optimal Air System, supply air temperature run between 45-52Â °F from the air handling unit to optimize energy consumption, reduce first capital cost and improve humidity control. Optimal Air has for years been extensively used in grocery stores and is gaining increasing popularity in comfort cooling applications such as offices and schools. 5.1 Advantages There are several benefits of Optimal Air that make it an attractive system for use in a wide variety of applications. It Saves Space and Reduces Energy and Construction Costs, increases the amount of sensible heat that each CFM delivered to a zone can absorb. While 50Â °F air may not seem much colder than 55Â °F air, the delta T rises from 20Â °F to 25Â °F. That is an increase of 25%. This affects the sizing of the ducts, air handling units and fan motors, all of which will be smaller and results in a system that requires less space and uses less power. In many applications, fans can use more power annually than refrigeration (chillers, condensing units, pumps, and compressors). An example of annual 10-story building energy usage of 200,000 square-feet of HVAC components, the fan energy use is high because the fans operate every hour the building is occupied providing minimum air movement, ventilation air, heating, etc. In this case, an Optimal Air system would have a very real impact on overall energy costs. Fig 4, Annual HVAC Energy Usage [6] 8 5.2 Less Humidity, more comfort Optimal Air systems take more moisture out of the return and ventilation air mixture as it passes over the cooling coil. The lower moisture content in the supply air reduces the Psychrometric balance point humidity level in the conditioned space. This allows the space temperature to be set higher while achieving the same comfort level for occupants and further reduces the supply air quantity and fan power requirement. 5.3 Quieter and Improve Indoor Air Quality (IAQ) The lower air volume required for Optimal Air systems makes them quieter than conventional systems. Fan sound generation is a function of fan type, static pressure and air volume. By reducing air volume (and often the total fan static pressure) Optimal Air systems generate lower fan sound which can result in more desirable space conditions. This reduced sound generation can also be used to reduce the cost of any required noise attenuation in critical applications. The lower required air volume can also be used to reduce filter face velocities, allowing more efficient filters to be used without high energy cost penalties. The lower air temperature and resultant humidity levels also reduce the chance of mold growth in the air handling units, ducts or the occupied space. The example of the building above requires a supply air of 26,667 CFM. The HVAC system is floor by floor VAV air handling units with a two chiller primary secondary system, Optimal air works equally well with applied rooftop units or indoor vertical self-contained units. Table 1, HVAC system performance with optimal air system [7] 9 Table 1 shows the HVAC system performance as the supply air temperature, to the duct, is lowered. It is important to differentiate between supply air temperature off the cooling coil and supply air temperature into the duct. To accommodate the lower supply air temperature, the chilled water supply temperature (CWST) was gradually lowered, the air handling unit coils deepened to allow for closer approaches, and chiller performance was adjusted to deal will the increased lift. Because of their basic operating differences, DX rooftop and self-contained systems may have a different Optimal Air temperature than a chilled water system. When considering multiple system options, it is important to use Energy Analyzer for each in order to identify the best option. 5.4 Optimal Air Balance Point Reduced fan energy must be traded off against increased refrigeration energy. This trade off varies with the type of building, the type temperature control system, the type air conditioning system and geographic locale. Therefore, the optimal supply air temperature is different for every job. When only energy costs are a factor and no thermal storage is involved, this optimal supply air temperature generally falls in the 47Â °F -52Â °F range. It can be determined by comparing total system energy consumption with varying supply air temperatures using an energy analysis program. 5.5 Space Design Temperature and Related Comfort Temperature, humidity, air velocity and mean radiant temperature directly influence occupant comfort. Conventional designs are usually based on maintaining 75Â °F and 50% RH (Relative Humidity) in the occupied space. Figure 5 shows the ASHRAE comfort zone where 80% of the people engaged in light office work are satisfied. As the relative humidity is lowered, the space air temperature can be raised and still provide occupant comfort. The leaving air condition from the air handling unit is the primarily control of the relative humidity in the occupied space. The internal moisture gains from people, kitchens, etc, as well as infiltration also play a part. 10 Fig 5, Equivalent comfort chart [8] In most climates, the lower the supply air temperature, the lower the humidity ratio and the drier the space. Figure 5 shows sensible heat ratio lines for conventional, Optimal and low supply air temperatures. As the space relative humidity is lowered, the space temperature set-point rises from 74Â °F to 78Â °F. 5.6 ASHRAE Compliance The 1999 and 2001 version of ASHRAE Standard 90.1, Energy Standard for Buildings except Low Rise Residential Buildings [9], has mandatory requirements for refrigeration equipment and prescriptive requirements for fan work. The Standard recognizes that Optimal Air systems improve fan work significantly and provides credits to account for improved fan performance. In addition, refrigeration system performance is rated at conventional conditions or special tables are provided to account for non-standard operating conditions (as is the case with centrifugal chillers). In either case, ASHRAE Standard 90.1 does not penalize Optimal Air systems. 11 5.7 Design Considerations Design of refrigeration and air handling equipment for an Optimal Air system is similar to the design of a conventional air temperature system. Attention must be paid, however, to air distribution, controls and duct design. Conventional diffusers, when properly applied, will work with Optimal Air. Controls also require only minor changes from conventional systems. In particular, programming of economizer controls and supply air temperature reset. Finally, the ducting system must be sized for the reduced air volume to take full advantage of the potential capital savings. Duct insulation and sweating should also be reviewed to provide a trouble free system. Not every building type is a good candidate for Optimal Air. When air volumes are dictated by air turnover rates, such as some health care applications, Optimal Air offers no advantage. In fact, there would be increased reheat costs. Office buildings are a strong candidate for Optimal Air. They have high sensible heat ratios and typically less than 20% ventilation loads. Schools can also be a possibility. Generally speaking, as the percentage ventilation load increases, Optimal Air becomes less attractive. Location and climate also impact whether or not Optimal Air is a good candidate. Locations where weather provides significant economizer hours between 45 and 55Â °F will limit the savings. Ultimately, each project must be checked by performing the applicable specific calculations. The following should be considered: Load and Balance Point calculations, Space Temperature Set-point evaluation, Design Load Calculation, Primary and Secondary System Selection, Parallel, mixing or series VAV-Fan powered boxes, Perimeter Heating, Air Distribution, Diffusers (based on air flow and the throw distance calculation), Duct design (considering duct heat gain, sweating and insulation). 5.8 System Life-Cycle Analysis Evaluating different engineering solutions is always part of a good proposal. Optimal Air systems are no different. 12 In the case of Optimal Air, there may be no need to do any calculations because Optimal Air systems cost less to build (lower capital cost) and have the same operating cost as conventional systems (assuming the balance point was used for the design). Duct sizing will decrease almost linearly with reduction in air volume. The installed cost will not change linearly because of the labor portion. A 20% reduction in air volume can result in 80% savings of the 20% reduction or 16% overall savings in sheet metal cost. On the plus side, there are less pounds of steel and fewer man-hours to install it. On the minus side there is more insulation. Terminal boxes and diffusers will be a wash since there are fewer of them but the equipment cost will be higher than conventional equipment. HVAC equipment will cost about the same. This is conservative because the air handling equipment will cost less and refrigeration equipment will be slightly more. There is typically more capital invested in air handling than refrigeration. Building envelope should be the same for new construction. In the case of retrofit applications, it will depend on the quality of the existing building. The cost of space may also need to be evaluated. Not accounting for space savings is conservative. There will be space savings but they may be difficult to realize. If enough plenum height savings can be realized to add another floor within the same building envelope, then that rentable space should be accounted for. Simple payback calculations do not take into account the cost of money, taxes and depreciation, inflation, maintenance or increases in the cost of energy. A more complete analysis should include Internal Rate of Return (IRR) and net present value (NPV). In the HVAC industry, many projects fail simple back (they are in the 5-year range) while passing IRR (they offer a 25% rate of return). Software analysis tools can be used to perform both energy and life-cycle analysis that include simple payback, IRR and NPV. 13 6. Conclusion Building owners and designers faced with increased concerns for energy saving and environmental stewardship search for cost effective system options for their projects. The DDC, integrated with a high-performance low-energy HVAC system as the Optimal Air system can deliver both low first costs and reduced energy costs in a new construction and retrofit applications. This integrated system will not only meet the efficiency and sustainability of its performance at the desired set-parameters, but when designed with advanced selection tools, installed with the most advanced DDC/BMS system, and supported by trained operators, will achieve both energy saving and long term rebound effect (pay-back), maximum human thermal comfort, in addition, it allows building owners to compare predicted energy use to actual performance, this leads to a flexible budgeting, further future system adjustment and energy consumption cut-back. The whole integrated DDC/BMS HVAC system function will also contribute in the environmental impacts reduction. In todays challenging energy efficiency, building owners need proven system that delivers the necessary performance to meet their integrated environmental sustainability and business goals [10].

Scandals :: essays research papers

Contemporary society is always portrayed as a civilized society, in which the sense of democracy has come to woven throughout the fabric of our lives. Thanks to the mass media, the public has become more informed about what is happening in the world, from the political field such as the state and national government to the business area such as the international stock market. At the same time, people are paying more attention to the leaders. Some insist that since the major mission of the leaders is to lead the whole group to succeed in the intense competition, a leader should try every means to achieve his goal rather than care much about the ethic and morality. Those from the other camp hold a strong belief that to be an effective leader, a public official must maintain the highest ethical and moral standards. As far as I am concerned, I prefer the latter point of view. In the following discussion, I would like to present several evidences to support my standpoint. First and foremost, a public official with high ethical and moral standards will set a good example for the society as a whole which does good to the improvement of the morality of the public. From ancient times to the present world, the public leaders always serve as a focus of the ordinary that treat the words and actions of the leaders as a sign of right. So what and how the leaders say and do would produce a far-reaching effect on the public. A case in point is Gandhi, the greatest leader in Indian history. He led a simple and hard way of living all his life and never wasted even one coin, , and this encouraged all citizens of India to spare no effort to work hard for a better further of their country and no one pursued a luxury material life. This illustrates that a leader with high ethical and moral standards promote a good ethos in the society. Meanwhile, high ethical and moral standards embodied in the words and actions of a public official would help him or her to gain the trust and support of the public especially of his or her subordinates which make his or her policy to be implemented more effectively and efficiently. Take Mao Zedong, the founder of our new China for example: in the period of hardship, he advocated that all Chinese should tie up their belts and try every effort to go through this difficult time.

Chinua Achebes Things Fall Apart - Womens Role in the Ibo Society Ess

Women's Role in the Ibo Society In the novel Things Fall Apart by Chinua Achebe, women of the Ibo tribe are terribly mistreated, and viewed as weak and receive little or no respect outside of their role as a mother. Tradition dictates their role in life. These women are courageous and obedient. These women are nurturers above all and they are everything but weak.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   A main character in the novel, Okonkwo has several wives. He orders them around like dogs. They are never to question what they are instructed to do; they are expected to be obedient. We see this early in the story, when Okonkwo brings Ikemefuna into his home. Okonkwo tells his senior wife that Ikemefuna belongs to the tribe and that she is expected to look after him. She in turn asks him if he will be staying with them for a long period of time. This sends Okonkwo into a fury. He snaps at her in a very degrading manner, "Do what you are told woman. When did you become one of the ndichie (meaning elders) of Umuofia?"(pg.12) Clearly she receives no respect. Later in the story we see this woman try to comfort Ikemefuna. She "mothers" him as if he is one of her own children. She tries to put him at ease and can almost instinctively feel how much he misses his own mother.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   In keeping with the Ibo view of female nature, the tribe allows wife beating. Okonkwo beats his youngest wife one-day because she was visiting with a friend and did not get home in time to prepare a meal for him. Another one of his wives tries to cover for her, when she is questioned as to whether or not the youngest wife has fed the children, before she left. Certainly she does this in effort to protect the youngest wife, knowing full well what she WOULD ... ...is sweet. But when there is sorrow and bitterness he finds refuge in his motherland. Your mother is there to protect you. And that is why we say that Mother is Supreme"(pg.116).   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The only glory and satisfaction enjoyed by the women portrayed in Things Fall Apart was being a mother. They receive respect and love from their children. They are strong for their children. The women are viewed as very gentle and caring. They are expected to take care of their children with the best of their ability and are trusted totally by their children. This honorable presentation of women is used by Achebe to identify women's role in the Ibo society. This presentation is necessary to show that women indeed play an important role in society.

Private Versus Public Indonesian Schools Health And Social Care Essay

Besides [ 2 ] , there is another paper that investigated the effectivity of private and public junior secondary schools in the Indonesian context. [ 8 ] studied the relationship between school pick and academic public presentation alternatively of school pick and future net incomes. [ 8 ] found that the academic public presentation of public junior secondary schools pupils was higher than private school pupils as measured by national concluding trial test tonss ( UN[ 1 ]) upon completion of junior secondary school. Therefore, contrary to Bedi and Garg, [ 8 ] believe that public junior secondary schools are more effectual than private junior secondary schools. [ 8 ] besides doubt that the positive consequence of private schools could outweigh the high quality of public schools ‘ input quality. This paper presents a re-examination of Bedi and Garg ‘s appraisal on differential net incomes of public and private junior secondary school pupils, which is the nucleus of their empirical analysis. Using Bedi and Garg ‘s sample informations set, I obtained contradictory consequences to them. I found that their decision is biased and misdirecting. I am besides concerned about the usage of some placeholders of school quality indexs in Bedi and Garg ‘s net incomes theoretical account. Bedi and Garg used three variables that do non specifically demo the quality of junior secondary schools. Alternatively, Bedi and Garg use variables that show the status of the last school attended. Hence, it may be either a junior or a senior secondary school. I believe the used of inappropriate placeholders of school quality may bias the cogency of Bedi and Garg ‘s net incomes derived function. Last but non least, Bedi and Garg used the individual imputation of average permutation to get the better of the losing information. I believe this attack may skew the findings. I used the up-to-date MICE ( multiple imputation by chained equations ) attack to handle the losing value job. Using MICE, I besides found contradictory consequences to Bedi and Garg ‘s as the public school alumnuss net incomes are higher than private non spiritual school alumnuss.2 Sample ReplicationThe first measure used to retroflex Bedi and Garg ( 2000 ) was to make an indistinguishable information set to Bedi and Garg ‘s. Bedi and Garg use the Indonesia Family Life Survey 1 ( IFLS1 ) 1993 to gauge the effectivity of private and public schools in Indonesia. The IFLS1 is a large-scale longitudinal observation of single and household degree on socioeconomic and wellness study. The IFLS1 trying strategy was based on states, so the samples were indiscriminately selected within states. Due to cost- effectiveness the study had took merely 13 out of 26 states on the Island of Java, Sumatra, Bali, West Nusa Tenggara, Kalimantan, and Sulawesi. They were selected to stand for about 83 per centum of the Indonesian population. In 2000, RAND as the major manufacturer of IFLS published the 3rd moving ridge of IFLS, so called IFLS3. Harmonizing to the RAND web site, the populace usage files and certification of IFLS4 should be ready by early 2009. Bedi and Garg do non explicate the ground they merely use the first moving ridge. However, I assume that Bedi and Garg do non utilize IFLS2 and IFLS3 as the research was conducted before the IFLS3 was publically released. Despite Rand has printing IFLS2 in 1997, the moving ridge does non incorporate employment informations that consists of net incomes and the figure of hours worked informations[ 2 ] [ htbp ] Comparison of Exclusion ProcessItemBedi and Garg ( 2000 )Fahmi*Initial income information 4900 7220 Had non proceeded beyond primary instruction 3391 5448 Had more than 12 old ages of instruction 291 274 Lack of information on hours of work 33 37 Missing information on school type 10 13 Reported incomes seemed incredibly high 3 9 Missing information on category size–41 Attend ( erectile dysfunction ) school more than 12 month ( miscoded )–45 Missing information on failed in primary school–1 Missing information on male parent ‘s instruction–214 Missing information on female parent ‘s instruction–80 Missing information on school location–6 Missing information on faith–2 Number of staying observation 1194 1050 * ) The Exclusion stairss follows Bedi and Grag ( 2000 ) and another exclusion procedure can alter the consequence. I created a sample informations based on Bedi and Garg ‘s counsel ( pages 467-468 ) . However, I failed to reproduce Bedi and Garg ‘s sample informations even though I merged all necessary files and cleaned the informations right. My initial sample informations set consisted of 7220 respondents who have net incomes and are no longer pupils. The size of the initial information was about twice Bedi and Garg ‘s initial sample informations with 4900 observations. Missing and miscoded informations and besides sample limitations reduced the information set by 6170 ( more than 85 per centum ) to 1050 observations. Most of the observations, 5448, were dropped as they had non proceeded beyond primary school, while 274 observations were dropped since they had more than 12 old ages instruction. Furthermore, I dropped 13 respondents due to losing information on the school type and 9 observations as they had either 99997 or 999997 on entire monthly net incomes. Finally, I exclud ed the staying 389 observations as they had either losing information, miscoded category size ( 41 observations ) , figure of months in school period per twelvemonth ( 45 ) , failed in primary school ( 1 ) , parents ‘ instruction ( 294 ) , state where school is located ( 6 ) , and faith ( 2 ) . Table 1 nowadayss the full comparing of the exclusion procedure. Bedi and Garg used the IFLS1 issued by RAND in 1996 ( DRU-1195-CD ) . On the other manus, I used the IFLS1 information set called IFLS1-RR ( re-release ) that updates the original IFLS1. [ 9 ] explains that IFLS1-RR revisions and restructures the original IFLS1 to attach to with IFLS2. The different construction of IFLS1 ‘s DRU-1195-CD and IFLS1-RR perchance causes the mismatch between my sample informations and Bedi and Garg ‘s. Bedi kindly sent the sample informations set, PUBPRIV.DTA[ 3 ]. Bedi and Garg create the file on 7 February 1998 which consists of 1527 observations and 231 variables. However, Bedi and Garg did non direct the do-file[ 4 ]. Therefore, I can non track the building of sample informations. I tracked the difference of the sample informations sets by comparing Bedi and Garg ‘s sample that consists of 1194 observations with my 1050 observations. I can fit Bedi and Garg ‘s sample by 745 observations. Of the staying 449 observations, 17 observations are unidentified and 305 are considered as losing information. On the other manus, Bedi and Garg ‘s sample does non incorporate 305 observations from my sample informations despite those observations do non hold losing informations. Of the 305 observations losing informations, 34 observations have no information on the figure of months in a twelvemonth go toing school and 32 observations have no information on category size. Bedi and Garg substitute the losing informations on those observations by utilizing a sample average alternatively of dropping the figure of observations. The staying 214 observations have no information on either male parent ‘s or female parent ‘s instruction. Bedi and Garg put â€Å" 0 † value on those observations alternatively of dropping them. Despite Bedi and Garg explicating the major exclusion procedure, they do non indicate out the permutation procedure on the 305 observations. On the other manus, I provide the sketch of the tracking procedure in Table 1. I present the complete comparing of drumhead statistics between Bedi and Garg ‘s sample informations and my sample informations from IFLS1-RR in Table 2.

Since my sample informations does non fit with Bedi and Garg ‘s sample, I can non reproduce all Bedi and Garg ‘s appraisal consequences. However, I continued the remainder of the appraisals by utilizing Bedi and Garg ‘s sample. Using Bedi and Garg ‘s sample I can retroflex Table 1 and 2 in Bedi and Garg ‘s paper. Table 1 in Bedi and Garg ‘s paper presents the descriptive statistics of all variables whereas Table 2 presents the descriptive statistics by type of school. I could retroflex the consequence of the coefficients on polynomial logit appraisal in Table 3. However, I could non fit the consequence on fringy effects of explanatory variables. Technically, I generated the consequence utilizing mlogit and mfx2 faculty on stata. I present the consequence on polynomial logit appraisal in Table 8 in appendix.VariableBedi and Garg ( 2000 )Fahmi( R ) 2-5MeanStd. DevMeanStd.

Private Ch is Private Christan and other.3 Selectivity VariablesBedi and Garg include the selectivity variables in the net incomes appraisals and the net incomes decompositions. Bedi and Garg argue that in Indonesia, the junior secondary school sorting is a consequence of parental pick and choice standards that in some instance may implement by the school. In doing the determination, Bedi and Garg assume that parents evaluate the benefits of go toing each peculiar school and they face four available school types, public, private non-religious, private Islamic and private Christian schools. The school screening that is based on choice standards is most likely true for public secondary school as they require a certain degree of concluding trial tonss before accepting the pupils. Bedi and Garg besides suggest that school sorting may non be exogenic and the pupil who has higher ability may be more likely to come in public secondary schools. Bedi and Garg used two-stage appraisal suggested by [ 5 ] to get the better of the selectivity prejudice job. To gauge the net incomes appraisal, Bedi and Garg ab initio used a polynomial logit theoretical account to bring forth the selectivity rectification term. In the 2nd measure, Bedi and Garg estimated the net incomes equations and included the selectivity variables or the opposite of Mill ‘s ratio ( lambda ) to the equations. The coefficient on lambda measures the consequence of non-random screening single, while either the positive or negative mark indicates the nature of choice. The negative coefficient indicates that unseen variables that influence school pick are negatively correlated with unseen variables that determine net incomes. Bedi and Garg compared the consequences of OLS decompositions and two measure decompositions to demo the consequence of choice prejudice on the theoretical account. Despite Bedi and Garg utilizing the two measure method used in many surveies on school effectivity, I am concerned about the consequences of Bedi and Garg ‘s appraisals on selectivity variables and decompositions with selectivity prejudice. To verify the consequences, I re-estimated the polynomial logit equation utilizing Bedi and Garg ‘ sample informations set that derived from PUBPRIV.dta. I used the two-step technique proposed by [ 3 ] . [ 3 ] created selmlog as a faculty in STATA on choice prejudice rectification when choice is specified as a polynomial logit. I used Lee ‘s method in selmlog option, since Bedi and Garg used Lee ‘s two-step method to gauge the theoretical account.

Using Bedi and Garg sample informations, the consequences show positive selectivity for public schools, private non-religious schools, and private Islam schools and negative choice into private Christian schools. The coefficient in private non-religious school and private Christian school equation are statistically important. This consequences contradict Bedi and Garg ‘s consequences. In Bedi and Garg ‘s appraisals, negative selectivity exists in public and private non spiritual groups, whereas positive selectivity nowadayss in private Islam and private Christian schools. The coefficient lambda is important merely in private non-religious school appraisal. The coefficient on the selectivity variable of public schools in Bedi and Garg ‘s is -0.089, whereas in my consequence it is 0.104. In private non spiritual schools and private Christian schools, Bedi and Garg ‘s are -0.848 and 0.031, while in my conse quences are 0.895 and -0.666. In private Islam appraisal, Bedi and Garg ‘s is 0.073 while in my consequence is 0.259. I present the full comparing of the two measure appraisals in Tables 9, 10, 11, and 12. Bedi and Garg point out that the negative coefficient on lambda was statistically important in private non spiritual school appraisal. Bedi and Garg used this determination to back up their statement that the strong negative choice consequence in private non-religious school reversed the public and private non-religious school advantage. However, utilizing Bedi and Garg ‘s sample informations set, I found that the mark of in private non spiritual is positive. The positive and important coefficient on lambda implies that a non-participant type in private non spiritual group will be given to hold higher net incomes. Non participant-type in private non spiritual schools are pupils from high socio economic sciences background. From the consequence of school screening in Table 3, pupils whose parents do non hold secondary instruction most likely attend private not spiritual schools. Therefore, the non participant type or the sub-sample of private non spiritual school are pupils whos e parents have high instruction or have high socio economic background. The negative mark on the selectivity variable in private Christian school implies that pupils from non-participant types in these group will be given to hold lower net incomes. Intuitively, pupils from low socio economic sciences backgrounds who study in private Christian schools will be given to hold lower net incomes.4 Net incomes DecompositionBedi and Garg used the Blinder-Oaxaca decomposition to gauge net incomes differential between public school and private school alumnuss. Bedi and Garg used the double decomposition that included some non-discriminatory coefficient vectors to find the part of the spread in the forecasters. Harmonizing to [ 10 ] , the two fold decomposition can be written as ( 1 ) where the inferior refers to the public schools group and the inferior refers to private schools groups. is the the natural logarithm of single net incomes. is a vector of ascertained features and is a vector of coefficients on ascertained features. is the individuality matrix and is a diagonal matrix of weights. Now the double decomposition is ( 2 ) where is the net incomes difference. The first constituent, , is the net incomes derived function that is â€Å" explained † by group differences in the forecasters. The first difference is besides known as measure consequence. The 2nd portion, is the â€Å" unexplained † portion. is the differences caused by favoritism and unseen variables. Bedi and Garg follow [ 10 ] who used the average coefficients between the low and the high theoretical account or. Reimers believes that the favoritism in in labor market could impact the net incomes of either the bulk or minority group. Therefore, Reimers suggests that the diagonal of D ( matrix of weights ) should be 0.5 to avoid the incompatibility in decomposition consequence. I re-estimated the Blinder-Oaxaca decompositions on Bedi and Garg ‘s ascertained net incomes differential utilizing Oaxaca. Oaxaca[ 5 ]that created by [ 4 ] , is a STATA technique which allows gauging the Blinder-Oaxaca decomposition net incomes derived functions in one bid[ 6 ]. I present the comparing of the reproduction on the Blinder-Oaxaca decomposition in Tables 4 and 4. Table 6 presents the comparing of net incomes differential utilizing OLS appraisal as the appraisal does non include the selectivity variable. The consequences of Bedi and Garg and my appraisal utilizing Bedi and Garg sample informations are similar. Despite some differences in the 3rd denary values, the consequences could be considered as minimally different. The consequences suggest that Bedi and Garg ‘s computation and my technique, utilizing Jann ‘s Oaxaca, produced similar end products. However, Bedi and Garg do non supply the standard mistakes or statistical trials for the difference. Harmonizing to [ 4 ] , merely a few surveies on the Blinder-Oaxaca decomposition are concerned about the issue of statistical illation. Jann argues that statistical illation in the decomposition consequences is necessary to bring forth equal reading. In general, my computations on Blinder-Oaxaca decomposition are similar with Bedi and Garg ‘s. However, there are some differences in the 3rd figure in some denary Numberss. For case, Bedi and Garg ‘s entire log net incomes derived function between public and private non spiritual is 0.316 whereas in my consequence the spread is 0.318. The consequences of Bedi and Garg ‘s net incomes decompositions should be treated with cautiousness because of two factors. First, Bedi and Garg do non supply the t-statistics or the standard mistakes of the difference. Second, the choice prejudice could hold appeared in the net incomes appraisals. Table 3 shows that the choice prejudice occurs in private non spiritual school and private Christian school appraisals. Therefore, the net incomes derived function in Table 4 on those two groups are biased.

This grounds is strong as the net incomes derived function is statistically important at 1 percent degree of significance. The difference in the explained features contributes to about 82 per centum as the spread is 25.4 per centum. This spread is significance at 1 percent degree of significance. It means that the variables included in the theoretical account could explicate the 82 per centum of net incomes differential between public school and private Islam alumnuss. The difference in unexplained features are 5.5 per centum. However, this consequence is likely non true as the difference is non statistically important.

This grounds suggests that ordinary least squares ( OLS ) appraisal every bit good as the net incomes differential decomposition in these two groups would be biased. Table 4 nowadayss the net incomes decomposition utilizing the two-step method. In this tabular array, I do non supply the spread between public and private Islam schools since the coefficients on selectivity variables of both the groups are non statistically important. The net incomes derived function between public school and private non spiritual school is 24.3 per centum and is important at 0.05 degree. The spread is lower than the net incomes difference calculated by OLS appraisal. The net incomes decomposition on OLS appraisal between two groups are 31.8 per centum. Therefore, the inclusion of the selectivity variable in the theoretical account corrects the net incomes spread of 7.5 per centum. Si milar with the net incomes spread between public and private Islam schools, the explained or observed features in the theoretical account contribute to most of the spread. The part of measure effects or ascertained variables to the spread is about 60 per centum and is important at 0.01 significance degree. This part is higher than the OLS appraisal that merely contributes 52 per centum to the spread. The spread on the unseen variable are little and non statistically important. This consequence contradicts Bedi and Garg ‘s decision that the strong selectivity consequence reverses the public and private non-religious net incomes decompositions. I agree that the selectivity consequence corrects the net incomes spread but it does non change by reversal the advantages of public schools over the private non spiritual schools. The net incomes derived function of two-step appraisal between public and private Christian schools corrects the spread estimated by OLS. However, all the differences are non statistically important. Therefore, I can non reason what is the net incomes differences between the two schools since the groundss are likely non true. This undistinguished consequence on net incomes spread may be caused by the little figure of observations in the private Christian school group. The figure of observation in this group is 73 whereas the figure of observations in public school group is 767.5 School Quality IndexsDespite my findings beliing Bedi and Garg ‘s decisions, the placeholders of school quality indexs may bias the cogency of Bedi and Garg ‘s net incomes theoretical account[ 7 ]. Alternatively of utilizing standard variables for school quality indexs such as teacher-student ratio, outgo per student, and degree of instruction of instructors, Bedi and Garg used three proxy variabl es: a dummy variable of whether the school has a soil floor ( DIRT FLOOR ) , the length of the school term ( MONTHS ) , and the figure of pupils in the category ( CLASS SIZE ) . The figure of observations that linked to the information of these standard variables for school quality are non equal[ 8 ]. I believe BG ‘s placeholders for school features ‘ variables could hold biased the consequences. Harmonizing to the manual book of IFLS1, DIRT FLOOR, MONTHS, and CLASS SIZE[ 9 ]supply information about the school features last accompanied by respondents. Therefore, some of the informations on these proxy variables will be biased for respondents who attend senior secondary schools. The 1,194 from informations observation set in Bedi and Garg ‘s survey, there are 519 observations that are non junior secondary school. In fact, Bedi and Garg merely focus on the quality of junior secondary schools.6 Missing Data TreatmentI am besides concerned about the losing informations intervention in Bedi and Garg ‘s paper. There are two variables in net incomes equations that have losing values: CLAS_SIZ and MONTH. CLAS_SIZ has 72 losing values whereas MONTH has 55. Bedi and Garg used a traditional attack, the average permutation, to get the better of losing informations on those two variables. Hence, Bedi and Garg replaced the 72 losing values in CLAS_SIZ and MONTH by 36.40461 and by 9.412534. Harmonizing to [ 6 ] average imputation is simple to implement, nevertheless, it has some serious disadvantages. First, average permutation will diminish the discrepancy of the sample as the decrease of the sample will under gauge the true discrepancy. Second, the appraisal of non additive variables can non be estimated systematically. Third, average imputation will falsify the distribution of and form of the imputed variables. [ 1 ] points out that average permutation would be the worst attack when there is big inequality in losing informations for different varia bles. Another traditional attack that is alleged the list-wise or instance omission may be applied in this theoretical account to get the better of losing informations job. However, This attack may give indifferent appraisal if the MCAR premises are met. MCAR or Missing Wholly At Random appears when the chances of losing informations do non depend on any other observed or unobservable variable. However, MCAR seldom happens in household or family study. In the survey about the impact of childbearing on wellbeing utilizing IFLS informations, [ 7 ] argues that the premise of MCAR is non sensible in the survey. Mattei believes that the premise of losing informations mechanism or MAR ( Missing At Random ) is more sensible. To avoid inconsistent prejudices or equivocal consequences, I re-estimated Bedi and Garg ‘s school pick and net incomes derived function utilizing the multiple imputation by chained equations ( MICE ) . Multiple Imputation was originally developed by Rubin ( Rubin1976, Rubin1977 ) and implemented as MICE for general used by [ 12 ] . In STATA, MICE is implemented utilizing mvis or ice[ 10 ].

Then, I used mim bid to gauge the polynomial logit and two-step net incomes equation utilizing the five imputed information set. I compared the consequence of utilizing multiple imputation and Bedi and Garg ‘s average permutation in Tables 6, 5, and 6. Table 6 presents the comparing of the selectivity variable of Bedi and Garg ‘s and my appraisal. Then, Tables 5 and 6 compare the OLS and two-step net incomes derived function utilizing individual imputation ( average permutation ) and multiple imputation ( MICE ) .

The coefficient on selectivity variable in private Islam school is -0.247, whereas Bedi and Garg ‘s lambda in the same group is 0.073. The coefficient on lambda in private non-religious and private Christian schools are statistically important. Bedi and Garg point out that the negative coefficient on the selectivity variable in the private non-religious school group reverses the high quality of the public school group to their opposite number from private non spiritual schools. Bedi and Garg province that the net incomes spread between public schools and private non spiritual schools are reversed from 31.6 per centum to -75.4 per centum. However, in MICE appraisal the important negative coefficient on selectivity variable merely reduces the spread from 31.5 per centum to 24.6 per centum as public schools are still superior than private non spiritual school. Furthermore, the spread that is caused by unexplained or unobservable variables alternatively adds a positive 8.8 per centum to the entire spread. Table 5 shows that there is a similarity in net incomes derived function of the private Islam group in Bedi and Garg ‘s and my appraisal. The entire spread in MICE appraisal is 31.4 per centum whereas the explained spread is 25.1 per centum. The discernible variable adds 5.5 per centum to the entire spread, however the coefficient is non important.

I found that the important negative choice variable in private non spiritual schools does non change by reversal the high quality of public schools over private non spiritual schools. I found grounds that public school alumnuss earn more than private school alumnuss. Bedi and Garg used the traditional average permutation to get the better of the losing information. This individual imputation attack is non appropriate and may bias the consequences. Using the up-to-date MICE ( multiple imputation by chained equations ) to handle the losing value, I found the public school alumnuss have higher net incomes than private non spiritual alumnuss. The negative coefficient on the selectivity variable does non change by reversal the high quality of public schools. The usage of some placeholders as school quality indexs in Bedi and Garg ‘s gaining theoretical account may besides bias the consequences. Bedi and Garg used three proxy variables that explain the status of last school attended. Since some of the respondents attended senior or higher instruction, hence, it may bias the cogency of the theoretical account.Mentions[ 1 ] Acock, A.C. Working with losing values.
