The Relative Advantages And Disadvantages of Pull-out vs Research Paper

The Relative Advantages And Disadvantages of Pull-out vs Classroom-based Communication Intervention - Research Paper Example o do so the following objectives were pursued during the course of the study: What are the research based evidences favoring either of the classroom or pull out interventions? Evaluation of the evidences available Critical analysis of the evidences to answer the fundamental question of which of the two interventions, i.e. of classroom based and pull out interventions, are more effective. B. Overview The process of inclusion forming the basis of classroom-based interventions can be traced back to 1950s when parents of children with disabilities started a movement leading to implementation of The Education All Handicapped Children Act of 1975 (PL 94-142), rendering mandatory free and appropriate education in the least restrictive environment for all children, regardless of disability. Consequently, resource rooms and self-contained classrooms for children with disabilities were included in schools. PL 94-142 was further updated in 1991 by the Individuals with Disabilities Education Act (IDEA) (Schooling et al., 2010). Despite the legislations and provision favoring inclusion, the consensus in favor of either of the intervention strategies is lacking. Proponents of classroom based intervention argue that inclusion simulates and therefore prepares the child for the real world, lack of seclusion and discrimination leads to enhancement of self esteem, it enhances social interaction and hence mutual bonding among regular and special needs children, and can also take advantage of peer based instructional programmes (DuPaul, 1998). Contrary to this, several concerns have been voiced for the efficacy of classroom based interventions. The lack of individualized instructions and adaptations by teachers for special children in regular classrooms as advised in PL94-142 has been the... The basic research strategy includes selection of topic, a research design appropriate for data collection, data collection and analysis, and finding answer to the research question on the basis of data. Nature of research designs that can be considered for providing evidences can be classified into two basic categories: descriptive and experimental. While descriptive research is appropriate for description of a process; experimental design is suitable for investigation of cause effect relationship. Thus the research strategy that are most rigorous with reference to their design and hence are considered to provide most important evidences are those that involve an experimental, quasi experimental or regression discontinuity design. This report makes a conclusion that classrooms and pull-out; both interventions have been and should be discussed in context to the special needs child; giving primary consideration to the goal of education â€Å"to promote learning and life skills for young people and adults†. Putting a child in either of these settings is as advantageous as it is disadvantageous. A collaborative learning model, where the child can be benefitted from both of these and protected from the shortcomings of both of these settings would be an appropriate and practical approach for education of special needs child, which is being practiced in form of mainstreaming. Mainstreaming requires the student to be taken out of a general education classroom to receive special education services for topic areas that they need additional support.

Occupational health and safety Essay Example | Topics and Well Written Essays - 750 words

Occupational health and safety - Essay Example OSH increases workplace productivity. This is because OSH stipulates that all organizations have the duty of care of ensuring that employees and other parties who may be affected by organizations undertaking are safe at all times. Moral obligations in this case involve the protection of the lives and health of employees. Because of measures that are put in place in respect to moral obligations, employees become less susceptible to injuries and harm and thereby making the realization of a more secure, sustainable and healthier workforce. This in turn leads to abated levels of absenteeism, heightened motivation and ultimately, improved productivity. It is against this backdrop for instance that the European Agency for Safety and Health at Work (EASHW) established the finding that for every Euro that is invested in OSH, the Return on Investment (ROI) that is realized falls between 3 and 5 Euros, due to reduced costs that stem from reduction in absenteeism. In the US, the issue of absent eeism is underscored by the data that released to the same effect. Specifically, the United States Bureau of Labor Statistics established that machine-related accidents and injuries alone claimed 64,170 cases that required long sick-offs, in 2008 alone. Similarly, more than a fourth of these injury cases required more than 30 days being spent away from work (Reese, 2008). The fact that following OSH stipulations entails the installation of workplace risk prevention and the enhancement of proper health and safety management means that cases dealing with serious harm and injuries on employees are assuaged. Cases where these injuries are commonly recurrent are concomitant with high employee turnover, as organizations are compelled to look for another source of manpower or skilled labor. Adhering to OSH in turn alleviates cases of terminal injuries and thereby reducing the chances of high employee turnover that would be incurred as an organization tries to replenish the size of its work force. In a closely related wavelength, adhering to the standards and stipulations set by OSH gives organizational productivity the quality of continuity and stability. With the aforementioned abated cases of injuries and harm on employees, a corporate entity is succored from the task of having to retrain and nurture fledgeling personnel to acquire the necessary skills and experiences that an injured team possessed. This is significant, since training and nurturing organizational workforce entails numerous workshop drives and training programs. Reese (2008) points out that an organization also benefits directly when it adheres to OSH regulations and standards. This benefit takes the form of increased security from the ravages of workplace accidents, malfunction and human error. This is because; OSH is broad enough to include interactions with other subject areas such as safety engineering, chemistry and industrial engineering. This is especially more pronounced in industries that ha ve inherently high proclivity to accidents such as mining, construction and crisis management which have over time developed safety procedures and methods as a way of managing physical danger at the workplace. For instance, since 1992, engineering workshops specializing in welding of components are to adhere to the Personal Protective Equipment (PPE) regulations, and thereby curtailing high chances for

Fast-talking Dames In The Films Essay Example | Topics and Well Written Essays - 500 words

Fast-talking Dames In The Films - Essay Example The film â€Å"Adams Ribs† constructs Amanda as a Fast-Talking Dame. Amanda is ahead of time in her career and speech. The film introduces a woman who after learning that her husband is having an affair with another woman, fires a gun at them but one bullet hits her husband on the shoulder. The case is allover in the newspapers. Banners family consists of both the husband and the wife being in the law profession. The case is received differently by the couple. This brings an argument in the family apartment because Adam is assigned the case on the prosecutor side while Amanda seeks the accused who agrees she represent her as a personal lawyer. Amanda sympathizes with the woman because she believes that it illegal for a man to cheat on his wife. This feeling pushes her to request the woman if she may represent her as the lawyer in the case because she believes in equality. Amanda tries to outweigh her husband in the career. Also, Adam cannot keep the pace of Amanda speech since she talks very fast when arguing in the house about the case she is representing the accused. This constructs Amanda as a fast talking dame. In the courtroom ,Amanda bases her argument on the issue that both sexes are equal. However, Adam reminds Amanda that there is a difference between a woman and a man but, Amanda argues that the difference is quite small, Adam still insists the difference is significant. This is traditional notion that mocks the female who try to compete with the men since they should be seen and not heard Finally, at the end of the case, Amanda is able to convince the judge who makes the ruling in her favor. Thus, Amanda’s client is not found guilty. Amanda seems to be very dominant in the film. Almost all arguments that arise she emerges as the winner due to her good command of speech that Adam find so hard to keep up with.

Study of protocols in a VoIP network Essay Example | Topics and Well Written Essays - 4000 words

Study of protocols in a VoIP network - Essay Example These applications later came out with voice conversation features in which users utilize computer headsets or IP telephone handsets in communicating with one another. Services like call forwarding, conference calling, voicemail, contact management and directory assistance were later added and paved the way for the creation of a new revolutionary technology - Voice over Internet Protocol or VoIP. This development has captured the attention of telecom regulators and operators who have now started to embrace the technology as one of their mainstream services. The two most popular protocols, H.323 and SIP will be discussed in this report. H.323 is a standard for the transmission of real-time audio, video, and data information over IP-based networks. The standard contains specifications on the components, protocols, and procedures required in providing multimedia communication over local-area networks (LANs), metropolitan-area networks (MANs), wide-area networks (WANs) and even enterprise networks (ENs). Applications of H.323 may include IP telephony (audio only), videotelephony (audio and video), audio+ data and audio+video+data. H.323 can also be used for point-to-point or point-to-multipoint-multimedia communications like videoconferencing. Based on these applications, it can be seen that the standard can be utilized in a wide market segment - from consumer to enterprise to telco services. The H.3 Versions The H.323 standard is specified by the ITU-T Study Group 16. Version 1 was formulated in 1996 and refers to visual telephone systems and equipment for LANs that provide a nonguaranteed quality of service (QoS). It is geared more for consumer applications via LANs and the Internet. Version 2 of the standard was formulated in 1998 to accommodate the introduction of new voice-over-IP (VoIP) applications and IP telephony. The absence of a governing standard for these applications resulted to incompatibility of PC-based equipment and PBX or PSTN-based peripherals, so the new H.323 version was defined. At present, there are moves to add new specifications to the standard for new applications like fax-over-IP networks, gatekeeper-to-gatekeeper communications, and fast-connection mechanisms. This will pave the way for Version 3 of the standard. Components The H.323 standard specifies four kinds of components: 1. Terminals. An H.323 terminal can either be a personal computer (PC) or a stand-alone device, running the multimedia applications. It primarily supports audio communications but can optionally support video or data communications. The primary goal of H.323 is to interface standard-defined equipment with other multimedia terminals. 2. Gateways. A gateway refers to the equipment used to provide connectivity between an H.323 network and a non-H.323 network. The H.323 network can consist of PCs and PC-based peripherals while a non-H.323 network can refer to a PBX or PSTN network. In order to achieve connectivity between these two dissimilar networks, translating protocols were developed for traditional telephony features like call setup and release. It should be noted that a gateway is not required for communication between two H.323 terminals within an H.323 network. 3. Gatekeepers. A gatekeeper is necessary if an H.323 network will be implemented with services such as billing, addressing, call-routing, bandwidth management and authorization and

The Power of the Mamluks and Il-Khanates Essay Example | Topics and Well Written Essays - 2500 words

The Power of the Mamluks and Il-Khanates - Essay Example The Il-Khanates, on the other hand, achieved power by giving their subordination to the main Kahn, Kublai, and the main empire, thus ensuring the support of a successful ally. Because they were originally not a Muslim culture, they were often attacked by the Islamic states surrounding them. Eventually, after the converted to Islam, they were able to solidify their faith and gain acceptance. Thus, both clans were able to earn power through their religion, although through different means. It's important to revisit the development of these two empires in order to see how their power bases were increased by their acceptance into Islam. First, it is important to revisit the original Mongol invasions. Something different happened after the Mongols had invaded a few Islamic empires; eventually, the Mongols were to become Muslim themselves. This was to play an important role in the development of Islam within the Il-Khanate. The invasions of Central Asia and Russia by the Chagatai Khanate and the Golden Horde did not have the negative impacts on the native Islamic faith that the Mongol invasion of Iraq and Persia both had. Even though the Mongols defeated the Islamic states, the Muslim faith did prevail, and the Mongols themselves, although the invaders, did, for the most part, convert to Islam. However, the Mongol conquering of Islam's heartland did result in some major changes for the religion. By conquering and disemboweling the current Islamic dynasties, the Mongols in stilled new ones, thus setting a new era for the religion. This new era would allow both the Il-Khans and the Mamluk to achieve power through Islam, although this power would not be implemented until a little later in history. In order to understand how this process came about, it is important to revisit the history regarding the Mongol conquering of Islam. The fighting in Asia began in the 13th century with Genghis Khan, who raided Persia and conquered several cities up until his death. By 1237, the Mongols were outside of Bagdhad, the center of the Abbasid caliphate. When the Great Kahn Mongke was elected in 1251, the decision to attack the Abbasid caliphate was formed. Mongke did not like that Islamic people worshipped a man who they seemed to view as even above the Khan. Thus, the Mongols attacked the capital, and came out victorious (Nichoole 82). Then, Mongke gave instructions to attack the caliphate only if it decided not to surrender. Of course, the caliphate did not, and they were largely unprepared to do battle with fighters as whorled-renowned as the Mongols. They had a large force, but were not as well trained as the Mongols. Another problem that emerged in the Islamic faction was the age-old battle between Sunni and Shiite, and the fact that the caliphate was a Sunni meant that many Shiites went over to the Mongol side, thinking they would regain power if they did saw. Also, many Christians joined the side of the Mongols, seeing the Mongols as possible saviors from the fate of Islam. Some of the Mongol army was, in fact, Christian, so this is perhaps one of the reasons why they were able to gather so much support. Many Mongol soldiers were careful not to destroy Christian churches and symbols, and this fact endeared the army to the

Geological Applications of the Stable Isotopes of Nitrogen

Geological Applications of the Stable Isotopes of Nitrogen Bruce Botton Hard rock, geological applications of the stable isotopes of nitrogen. Introduction. Gammon and Ebbing book of general chemistry define isotope as â€Å"an atom with the same number of protons, but differing numbers of neutrons. So isotopes are just different forms of a single element.†[ Gammon, Ebbing. (2005). (8th ed., p. 467)] There are two broader definitions of isotopes, light isotopes are elements that are lighter (contain less neutrons) than the common more stable element (eg. 12O,26S and 34Cl) and Heavy isotopes are the atom contains greater number of neutrons than the most common form( eg. Fe, Cu and Zn). Focusing on light stable isotopes in low temperature environments such as H, C and O and with specific reference to Nitrogen isotopes. Below are a few properties of light stable elements: They are usually of low atomic masses. The mass difference between the heavy, uncommon isotopes and the common light isotopes is usually very large. The lighter elements form bonds with more covalent properties. These light elements form a large number of compounds that are found in the natural environment. Exist in more than one oxidation state. The relative abundances of isotopes are high enough for precise determination of isotropic ratios by mass spectrometry. Sedimentary rocks, low grade igneous and metamorphic rocks (ie. That form at temperatures of 350 degrees Celsius and less) are the type of rocks that we are expecting to find these stables isotopes of interest. Any temperature above this constitutes as high temperature geochemistry. The use of isotopes in analysis of rocks is of increasing popularity, it uses the variations in isotope abundance of various elements to determine certain properties of a rock. These properties that are available are origin and age of the rocks; air or water bodies and even to see if there has been any mixing of magmas to change the composition of the rocks. Stable isotope geochemistry is mainly focussed on the isotropic variations from mass dependant isotope fractionation as compared with radiogenic isotope geochemistry which uses the products of natural radioactive decay (eg. Half lives). Equation 1. Enrichment factor equation. Many isotopes the amount of fractionation that an atom or body of molecules undergoes is very small (both kinetic or equilibrium), so small measured in parts per thousand or less. The formula above shows us the enrichment factor that is present in a sample. This formula uses the ratio of heavy isotopes to light isotopes as compared with a standard sample. So for nitrogen we will be using 15N/14N For the purpose of this assignment, we are focusing on the use of nitrogen and its two isotopes 14N and 15N in the analysis of hard rocks. Nitrogen is a colourless, odourless tasteless and most commonly a diatomic non metal gas, it actually makes up 78% of the Earth’s atmosphere. Not only is it over three quarters of our atmosphere but it is a part of all living tissues and is an essential part of life as it is part of DNA and therefore important in the genetic code and the evolution of life. The nitrogen cycle (figure below) is an essential part of existence on earth. Nitrogen cycle. Figure 1 . Schematic diagram of the Nitrogen cycle.[ Petrucci, et al (2002). (8th ed., pp. 887–889). Prentice Hall.] There are 9 stages of the nitrogen cycle, there is no start point the nitrogen cycle is a complex, continous and simultaneous system. Nitrogen fixation: this is a chemical processes by which atmospheric nitrogen is transformed into organic compoundsby microorganisms. N2 à ¯Ã†â€™Ã‚   NH4+ à ¯Ã†â€™Ã‚   N-org Ammonification: this process is a conversion of organic nitrogen to ammonium by bacteria. N-org à ¯Ã†â€™Ã‚   NH4+ Nitrification: this is a process by which a nitro group is substituted for another group in organic compound. NH4+ à ¯Ã†â€™Ã‚   NO2 à ¯Ã†â€™Ã‚   NO3 Assimilation: is the conversion of nutriment into a usable form that is incorporated into human tissue and organs after digestion NH4+ à ¯Ã†â€™Ã‚   N-org Dentrification: is a process by which microbacteria breaks down a nitrate to produce N2. NO3 à ¯Ã†â€™Ã‚   NO2 à ¯Ã†â€™Ã‚   NO à ¯Ã†â€™Ã‚   N2O à ¯Ã†â€™Ã‚   N2 Volatilization: in this instance it is when liquid ammonium is transformed into ammonia gas. NH4+ à ¯Ã†â€™Ã‚   NH3 gas Case studies: Nitrogen isotopes in peridotitic diamonds from Fuxian, China: the mantle signature. Nitrogen is of low abundance in the earth’s mantle due to lack of knowledge. But fibrous diamonds are a N rich form and are associated with MORB vesicles these have been tested and give a ÃŽ ´Ã‚ ­15N value of -5†°, the reason for a negative value is due to it being a relative value to the external sources (atmosphere) This has lead people to believe in the heterogeneous accretion model of the earth. In Pierre Cartigny et al experimental procedure they separated diamonds into broad categories, type 1 has no nitrogen and type 2 does not contain any Nitrogen. These abnormalities are linked to diffusion process and might help tell us if diamonds formed in multiple steps. The nitrogen and the ÃŽ ´15N were measured with accuracy  ±2.5% and 0.5% respectively. After IR analysis 25% of the diamonds taken from Pipe 50 were determined as type 2 , and the remainder a mixture of type 1 and 2 diamonds. These ‘mixed diamonds’ are separate platelets compacted together, this zonation of the aggregated states of type 1 and type 2 platelets conform that the octahedrally shaped diamonds growth was over a extended period. 25% of the samples that were analyzed were found to have a lower value of a ÃŽ ´Ã‚ ­15N the in previous works ranging from -12†° to -25†° and the nitrogen concentrations vary from 0 to 1473 ppm. Below figure 2 shows us the ÃŽ ´ 15N histogram which show us fibrous diamonds from all over the World and the octahedrally shaped diamonds from pipe 50, the result as can be seen is that they are based around the same value ( -7†° and -5†°). These results are coincidently similar to the ÃŽ ´13C; this shows us that the fractionation of stable nitrogen isotopes during non fibrous diamond growth is unlikely. The growth of octahedral shaped diamonds should be seen as a large open system with limited supply of volatiles and periods of time in which resorption can occur. Geochemical evidence shows fibrous and peridotitic diamonds originate from similar sources, believed to be the convecting asthenosphere with values of ÃŽ ´Ã‚ ­15N being -5  ± 2 and -4.5  ±1†° respectively. If we wanted to strengthen this argument we would have to look at Diamonds that are found in the lower mantle. These diamonds would originate from a less degassed mantle, this would mean that there wou ld be little to no nitrogen present. If the nitrogen content is controlled by rate of growth rather than the carbon nitrogen ratio of the fluid, this means that there will be little or no correlation between N and ÃŽ ´Ã‚ ­15N, and even less between ÃŽ ´13C and nitrogen which is present in this case. [ Geà ¢ochimie, et al. (1997). Terra Nova, 9(4), 175–179.] Figure 2. histogram comparing ÃŽ ´15N values of diamonds from pipe 50 kimberlites and previously analysed fibrous diamonds.[ Geà ¢ochimie, et al. (1997). Terra Nova, 9(4), 175–179.] Concentrations and isotope ratios of carbon, nitrogen and sulphur in the ocean floor basalts. The concentration of stable isotope ratios in fresh basalts on the sea floor provides us with information on abundance and isotope ratio of volatile elements in the upper mantle and crust. Samples were taken from less than 10mm from billow basalt ridges and then other samples were taken from the inner portions of the pillows where the groundmass ranges from glassy to crypto-crystalline. The isotropic ratios ÃŽ ´ was atmospheric nitrogen and the uncertainties was  ±1†°. The contents and the ratio of nitrogen present in the ocean floor basalts range from 0.3 – 2.8 ppm and from -0.4†° – 0.8†°. The nitrogen that was attained was of one order of magnitude bigger than the blank nitrogen cycle. This said but the uncertainties in the experiment were rather large  ±1†°, this is due to the small sample sizes. This said, the discrepancy of the isotope ratios should not be taken to be significant but the uniformity of the isotropic ratio and their similarity to the N2 ­ in the air should be emphasized. Nitrogen’s most common form in igneous rocks is in the form of N2 ­ and ammonia. When nitrogen vapour is in contact with magma it would most likely exist as N2, but if it is in the magma it will most likely be in the form of ammonia. The nitrogen in the magma itself will most likely escape as N2 from ascending magma and decreasing confining pressure and will act as a alkaline cation when undergoing fractional crystallization and therefore will be more evolved in a more evolved magma. As Degassing and fractional crystallization proceed NH+4 is enriched relative to N ­2, and NH3 would become depleted and more enriched in 15N this means that 15N/14N in igneous rocks increases with decreasing nitrogen content. According to Sakai, H et al. The average ÃŽ ´ 15N of magmatic crust, atmosphere and sedimentary rocks are 4.2, 0 and 5.2†° respectively. Therefore the global distributions of nitrogen isotopes have been interpreted as the result of out gassing of magma and fractiona tion between N2 and NH+4. ÃŽ ´15N found in MORB are close to the crustal values and therefore can be said to support the above model. Conclusion: Finally in conclusion we can see the importance of nitrogen not only in the atmosphere and our very being. But we can see that there are uses for the stable isotopes in the continued attempts to try and understand the Earth’s history and origin. Reference list: Gammon, Ebbing. (2005). General Chemistry.
