Academic performance of disabled students and their general education peers Essay

Calls for the evolution of the educational system to maintain an inclusive program for mentally, financially and physically disabled students have been supported by the arguments that inclusion will greatly benefit the academic and social performance of children with disabilities. This is true since academic learning is enhanced when a program expecting higher output and reinforcing higher standards exists for students. These opportunities allow them to work and study harder as it exposes them to what many believe are normal real-life standards. Friendly and Lero (1993) stress that a motivation to keep up and progress without outside assistance is a driving force of enhancing performance. They also note that the labels in homogeneous or ability groupings negatively affect student potential. Contrastingly, although the effects of the inclusive system of education are favorable for non-general students, Brackett (1994) stresses that the opposite might take effect for general education students. These children might experience boredom due to the considerations given to disabled students in terms of pace and activities. Special or disabled children may also experience frustration as they try to keep up with the normal learning pace in a heterogeneous mix of students. Despite these contentions, several studies also note the positive effects of inclusion to the academic performance of both general education children and special needs education students. Hines and Johnston (1997) reported that disabled students in an inclusive set up showed academic progress and performance and improved their behavior as well. Schattman and Benay (1992) attribute this to the wide exposure of the disabled children, in an inclusive set up, to creative teachers and the nature of the inclusion strategies to expose the children to social interactions with other students. The marks and learning abilities of disabled students on specific subjects were also positively affected by being in inclusive classroom situations (Barbetta et al, 1991). The effect of inclusion to regular classroom students has been extensively studied and Staub and Peck (1995) list the general outcomes of the exposure of this group to this new learning environment. It has been noted that regular class students, after being exposed to an inclusive situation, become more aware of existence of human diversity and have reduced fear of human differences. They have more social interactions which results in a keener awareness of self knowledge. In addition, they also learned to develop their personal principles at an early age and the increased frequency of social relationships allowed them to create more friends. Hollowood et al. (1994) also answers a thriving concern about the imbalance of time allotment for students by teachers when exposed to an inclusive environment. It has been observed that the presence of special needs students in a class does not interfere with the allocated time of teachers to regular class students. And although, interruptions have been observed in some cases, the downtime did not significantly alter the average instruction hours when compared to general education classes. Similarly, in a study of primary and secondary schools that adopted inclusion, Idol (2006) reports that in a four-year study of four elementary and secondary schools, most students are generally not affected by the presence of students with disabilities in their classes. Statistics on these schools show that the elementary students surveyed registered a 68% approval rating on student performance and the respective elementary and secondary students show a 36% and 24% rating that student performance in inclusive situations was higher. 32% and 34% of elementary and secondary students also agree that academic abilities remained constant. In the four elementary schools considered, only 6% of the educators responded that there were negative reactions brought out by the presence of disabled students in class, while the statistics in the secondary schools surveyed did not vary much at 8%. The teachers also reported that a larger chunk (> 50% ) of the students increased or retained their statewide test scores. Requirements for an effective strategy Dugan et al. (1995) reviewed several studies which have been published regarding the methods and strategies used in inclusive education. According to this paper, improved academic performance is assured (Kamps et al. , 1992; Madden and Slavin, 1983; Noonan & Hemphill, 1984; Shores et al. , 1993; Stainback et al. , 1981) if the program consists of a 1. method to encourage and guide interaction among students with disabilities and their peers; 2. scheme where teachers employ adaptive measures of instruction for students with disabilities; 3. program of study that enjoins both disabled and normal children to equally participate in activities; and 4. training to improve the social interactions and abilities of a child that prepares him for the real world environment. One aspect of inclusive education that employed cooperative learning groups is also effective in enhancing the performance of students. Johnson et al (1990) notes that cooperative learning results in improved academic performance of children from different cognitive levels to be in a heterogeneous educational environment that promotes the mediation of groups for maximal learning. Inclusive education programs and strategies like the cross-age tutoring also resulted in improved performance of both students with and without disabilities (Barbetta et al. , 1991) and increased the reading and comprehension abilities of both normal children and children with autism (Kamps et al., 1994). Kamps et al (1994) also note that because of the drastic improvement in the confidence of the children in a cooperative learning set up, the time for interactions and social activities between children with autism and their peers also increased and adds to their improved learning abilities. According to Dugan et al (1995) cooperative learning groups improved student interaction through increased frequency of social activities. The effectivity of student learning also increased due to tutoring events and research activities. Hawkins et al (2001) explained that early social interactions between children create a deeper bond that acts as a defense for behavioral problems and, thus, strengthens the relationships of students. Strategies for improved academic performance Academic performance in an inclusive set up uses contemporary schemes in order to teach the lessons to students. Learning is boosted through techniques such as teams games tournaments or TGT, which allows the teacher to teach the lessons to students through games. The teams cooperate and learn from other group members by peer tutoring in order to increase their chances of winning in the tournaments. Another scheme called student teams and academic divisions or STAD allows individual members of a team to score points by adding their individual written scores, like in a quiz for example, to the total accumulated team points (Slavin, 1990). Another inclusion strategy that shows very promising results in increasing the academic fervor of children involves the use of class wide peer tutoring (CWPT). In a study of the performance of heterogeneously grouped children under the subject of reading and reading comprehension, CWPT was observed to increase the ability of students to read and pronounce words accurately and answer reading comprehension questions correctly. The technique was also found to improve the cognitive skills of elementary students with autism. It was also a tool for social interaction and learning with their classmates and showed better reading proficiencies for most students because of the relative ease in adapting this program to a normal classroom set up (Kamps et al.,1994). CWPT can also be incorporated in a team games tournament (TGT) scheme and are collectively referred to as class wide student tutoring teams (CSTT). This method employs tutoring and tests individual learning progress by competitions where individual scores comprise team scores. Reading can also be taught to elementary students through a cooperative integrated reading and composition technique or CIRC. In this strategy, students are paired and are allowed to read stories to each other while practicing and honing their reading abilities (Jenkins et al., 1991). Johnson et al (1984) reports that role playing is also a learning strategy to be employed, this technique, called circles of learning, employs group dynamics and allows students to complete assigned tasks and evaluate their performance through worksheets. In addition, the competitive atmosphere is reduced because of the nature of the activity. These techniques have been shown to improve the academic performance of a heterogeneous mix of students with different baseline aptitudes. The case of employing inclusion to disabled children and high-level students with autism can also be employed to children who are sickly, obese or those with high risks of cardiovascular diseases. Van Sluijs et al. (2007) have observed that the method of inclusion to obese adolescents shows strong evidence of improvement and increased physical activity. The effective strategies employed actively involve the school, the community and the student’s family in order to improve the physical disposition of the individuals in the study. Studies show that a key factor in the improvement of students in inclusive setups is the competency of educators handling the classes. However, every teacher has his own techniques, experiences and teaching strategies that he has developed over time. This difference in experience is especially large between teachers who handle exclusively special classes for disabled students and those who handle general education. Thus, in an inclusive setting, in order to expand the exposure of students to different teachers, collaborative teaching has been developed as a strategy for effective learning. This method is a big deviation from the previous pull-out system for partial inclusive settings. In co-teaching, both teachers complement and co-teach both disabled students and their peers (Gerber and Popp, 2000). Rea et al (2002), in a study on the teaching practices of Enterprise Middle School which handles grade school students at levels 6 to 8, show that co-teaching is an effective strategy for educating students. This mechanism involves daily class rotations with different teachers. Co-teaching also requires careful and synchronized planning on the part of the educators. Teachers actively and regularly discuss their activities and lessons and share methods of evaluating the progress of students. This way, different instructional objectives are met although by different individuals. This is necessary to coordinate and pace teachers in their work and lessons with their students as well as to share information on student development. Different schemes characterize the co-teaching method. Rea et al (2002) note that interactive teaching or taking turns observing and lecturing may be employed. The class may also be divided for parallel sessions or one teacher may be assigned for catch-up classes for some students. Nonetheless, any form taken by the co-teaching scheme aims to provide for the needs of the children, supplied variation in teaching techniques, and was seen as a healthy environment for student growth and learning. Many researchers have expressed support to the principle of including disabled students in general education practice. Among them, Villa et al. (1996) have observed that educators preferred teaching disabled students along with their non-disabled peers. This factor may have contributed to the increased academic progress of students within the inclusive education set up. On the other hand, Thousand and Villa (2000) stressed that teachers are not the only major contributing factor to student progress. In fact, they highlight the observation that inter-student relationships while in the confines of the classroom play a big role during learning, emotional and social development. As the needs of the children in an inclusive set up are congruent to the skill that must be possessed by the educators handling the classes, teacher training (Porter, 2001) is an essential part of the process that makes an inclusive set up work. Daniel and King (1997) refer to this skill as training for inclusionary practices and is a characteristic of teachers that must be developed in order to function effectively in an educational system following heterogeneous groupings. It should, therefore, be apparent that these special skills allow educators to adapt to the wide needs of different types of students and allow them to be creative in forming strategies for an efficient and effective learning experience for both disabled students and their peers. However, the great demands of the inclusive educational practice oftentimes result in work pressure among teaching personnel. For example, studies on all elementary physical education instructors from Israel show that the episodes of burnout in faculty members are related to the number of special or disabled students in their classes and the amount of assistance they get conducting these classes (Fejgin et al. , 2005). This relates the demanding work that is put in by the educators in order to make an inclusive program work. This study also stresses the chief role played by government support in the educational system, where episodes of teacher burnout are also dictated by poor quality of the workplace and inadequacy of the institution to provide sports facilities for the needs of the students, especially the disabled or special cases. Despite episodes of burnout, most teachers have expressed their support for inclusion as an appropriate program to teach disabled children (Idol, 2006) the statistics is expected to improve if more educational personnel were available to answer to the needs of all students. The necessity for improved and evolving programs that would answer the needs of students in inclusion also requires the involvement of many organizations, individuals and different types of educators, resulting in interdisciplinary interactions to improve current conditions (Robertson and Valentine, 1998). This brings about an atmosphere of community and exposes the teaching skills of effective teachers and allows room for growth and improvement. Equally important to the instructors are the provision of adequate health care safety facilities for different types of students which should be provided by the government and their policy makers. It is consequently very crucial that an educational program should be backed-up by community and policy driven education reform for a successful advocacy. Porter (2001) expresses that there is a need for legislators who understand that an inclusive community school is a method of reform that should be supported. For cases of students with severe autism and retardation, however, further studies both on the effective procedures that should be employed and on the qualitative measures of investigating the effects of peer-mediated activities and cooperative learning also require continuous evaluation (Kamps et al. , 1994). Nonetheless, Kamps and Carta (1989) note that strategies are successful if these improve or maintain the skills of non disabled students without compromising the learning of their disabled peers.

The Common Indoor Air Pollutants Environmental Sciences Essay

Air pollution is an look used to depict the air province when the concentrations of chemicals, particulate affair, or biological agents in the air exceeds the recommended degrees and became a beginning of wellness jeopardy or do uncomfortableness to worlds and other beings, or cause amendss to the populating natural environment. Pollution can be resulted from semisynthetic day-to-day industrial procedures and activities or by the nature. There are many signifiers of pollutants solid atoms, liquid droplets, or gases. Indoor air pollution can be arises from indoor and out-of-door pollutant beginnings. Peoples, particularly pupils, spend about 90 % of their live in sealed controlled environments, EPA ( 2001 ) . These sealed environments may hold pollutant beginnings that could hold short or long effects on residents ‘ wellness, comfort, wellbeing, morale and productiveness. The strength of the effects depends on the degree of the quality of the inside air ( pollution degrees ) . In recent old ages, the issue of indoor air and its quality ( IAQ ) has become an internationally recognized issue that caught the attending of research workers and the residents toward bettering the quality of air inside edifices environments. Fanger ( 2006 ) defines the indoor air quality ( IAQ ) as â€Å" the desire of human to comprehend the air as fresh and pleasant, with no negative impacts on their heath and productiveness † . Many research workers such as Wark and Warner ( 1981 ) and Singh ( 1996 ) investigated discussed the beginnings of the outdoor and the indoor pollution that affect ed the indoor air. They found that the indoor air quality can be influenced by the out-of-door air pollution beginnings such as traffic ; industrial ; building, and burning activities and the indoor beginnings such as airing equipment, trappingss, and human activities. Common Indoor Air Pollutants In this subdivision, the common indoor air quality parametric quantities and its outdoor and indoor beginning in add-on to it is wellness jeopardy on human shall be discussed. The common IAQ parametric quantities consists of three physical parametric quantities ( room temperature, comparative humidness, and air motion ) related to residents ‘ thermal comfort which is defined in the old chapter, eight gaseous contamination parametric quantities ( sulfur dioxide ( SO2 ) , nitrogen dioxide ( NO2 ) , C monoxide ( CO ) , C dioxide ( CO2 ) , formaldehyde ( HCHO ) , radon ( Rn ) , ozone ( O3 ) and hydrocarbons ) and three airborne contaminations parametric quantities, particulates affairs ( PM ) ; bioaerosols ( bacteriums, viruses, Fungis and pollen, aˆÂ ¦etc ) and dusts, In add-on to the treatment of olfactory properties. Sulfur dioxide ( SO2 ) This type of pollutant gas has been extensively studied by many research workers around the universe in out-of-doorss environments due to it is high inclination to respond with broad scope of chemicals. SO2 is a colorless gas with a characteristic pungent olfactory property and consequences from the fossil fuels burning. Acid rain is one of the out-of-door pollution job cased by this gas. Indoor SO2 concentrations are normally lower than outdoor, likely around 0.1 ppm, ( Andersen 1972 ; Yocom, 1982 and Meyer, 1983 ) . Due to it inclination to respond with many chemicals, indoor SO2 can respond with edifice stuffs and absorbed by the edifice surfaces ( Andersen 1972 ) . This gas can fade out in H2O and mixes with air in all temperatures. The chief indoor beginnings of SO2 are coal firing inside hearths and utilizing fuel oil ranges and warmers. Sulfur dioxide causes concern, general uncomfortableness, anxiousness, and redness of the respiratory piece of land, wheezing, lung harm, and annoyance of the eyes, nose and pharynx, choking and coughing, ASHRAE ( 2009 ) . Nitrogen dioxide ( NO2 ) Nitrogen dioxide is caustic gas with acrid olfactory property and formed in outdoor atmosphere from high temperature burning procedures by the reaction of the azotic oxide ( NO ) with Oxygen ( O2 ) and Ozone ( O3 ) . Motor vehicles contribute to about 55 % of the manmade NOx emanations, EPA ( 2008 ) . The major beginnings of this gas in indoors environments are gas cookery ranges and warmer and baccy fume, Samet et al. , ( 1987 ) . In a survey done by Yocom ( 1982 ) among British school kids it was found that pupils whom suffer from reduced respiratory map are populating in houses with gas ranges. Exposure to low degrees of Nitrogen dioxide ( NO2 ) causes shortness of breath, fatigue, sickness and annoyance to the eyes, nose, pharynx, and lungs ; exposure to high degrees cause rapid combustion, cramps, swelling of tissues in the pharynx and upper respiratory piece of land, reduced oxygenation of organic structure tissues, a build-up of fluid in the lungs, and may take to decease, ( Burgess and Crutchfield, 1995 ; Bascom et Al. 1996 and ASHRAE, 2009 ) . Carbon monoxide ( CO ) CO is a really toxicant asphyxiant and non irritating gas that has no colour, olfactory property or gustatory sensation. This gas produced by the uncomplete burning of carbon-based fuels ( Yocom, 1982 and Meyer, 1983 ) . Vehicular fumes is a major beginning of C monoxide, ( Moolenaar et al. , 1995 ; Girman et al. , 1998 and EPA, 2008 ) . The indoor C monoxide concentrations are frequently higher than the out-of-door concentrations due to the emanation from gas ranges and baccy fume, ( Yocom, 1982 and Girman et al. , 1998 ) . The chief consequence of this gas on human wellness is its affinity for haemoglobin in blood. The inhaled CO mixes with the haemoglobin in the blood and signifiers carboxyhemoglobin that reduces the O transporting capacity of the blood vass. CO is 240 times more efficient at haemoglobin adhering than Oxygen, ASHRAE ( 2009 ) . Exposure to carbon monoxide causes concerns, shortness of breath, musculus achings, chest hurting, particularly in people with old bosom jobs history, blurry vision, giddiness, nausea/vomiting, failing, confusion, weariness, rapid bosom rate at high degrees, fast deep external respiration at high degrees, fainting and decease at high degrees, CPSC ( 2008 ) . Carbon dioxide ( CO2 ) Carbon dioxide is a colorless, odorless, asphyxiant nursery gas emitted from the complete burning of the C with Oxygen. The mean typical concentrations of CO2 in the outdoor and indoor ( nonindustrial ) environment are 350-400 ppm, and 400-1200 ppm, severally, ASHRAE ( 2009 ) . The chief beginnings of the indoor CO2 are human organic structure through the metamorphosis procedure ( nutrient ingestion ) , and residents ‘ activity. The wellness jobs associated with C dioxide exposure are concerns, giddiness, restlessness, feeling of an inability to take a breath, unease ( obscure feeling of uncomfortableness ) , increased bosom rate, increased blood force per unit area, ocular deformation, impaired hearing, nausea/vomiting, loss of consciousness, coma, paroxysms, decease from suffocation ( organic structure cells do non acquire the O they need to populate ) , EPA ( 2008 ) . Formaldehyde ( HCHO ) Formaldehyde is a colorless with a strong pungent olfactory property and considered as the most of import substance in the aldehydes group due to it is largely used in the production procedure of many constructing stuffs such as foam insularity, plyboard, rugs, burning contraptions and atom board adhesives which releases once more the methanal to the indoor environment. The typical indoor methanal concentrations range from 0.05 to 1 ppm, where in the new edifices the indoor degrees of the methanal are high, ( Meyer, 1983 ; Samet et al. , 1991 ) and most of the complains were from edifices with formaldehyde froth insularity and nomadic places that uses plyboard panelling, Wadden ( 1983 ) . The rate of diffusion of this substance is a map of the indoor temperature and humidness. Exposing to formaldehyde can do wellness effects include oculus, nose, and pharynx annoyance ; wheezing and coughing ; weariness ; skin roseola ; terrible allergic reactions, EPA ( 2008 ) . High concentrations of methanal may do malignant neoplastic disease and other effects listed under organic gases. Radon ( Rn ) Radon is an inert radioactive, colorless, odorless, tasteless baronial chemical gas component. Naturally, this component can be found as dirt gas contained Rn formed from the decay merchandise of uranium and can stay as a gas under normal environmental conditions. This contaminant component can be found indoors due to some beginnings such as edifice stuffs particularly that rich with Ra, such as alum shale-based stuff and phosphogypsum drywall, deep Wellss H2O natural gas holding high Rn concentrations. Another chief beginning is the flow of the dirt gas into the places through edifice clefts, sumps and any other gaps or around the concrete slab, Bale ( 1980 ) . Due to tightness of the edifices design, the indoor concentrations are normally higher than that in out-of-door environment. Recently, this component is considered as carcinogen component du to it is radiation, which has a critical wellness jeopardy on edifices residents, where it is considered to be the 2nd most ground of lu ng malignant neoplastic disease after coffin nail smoke, EPA ( 2008 ) . Ozone ( O3 ) Ozone is a really reactive pollutant that can oxidise most of the chemicals in nature such as aldehydes. In natural outdoor environment, Ozone produces from the consequence of the sunshine on the N oxides and hydrocarbons. Normally the Ozone concentrations in the out-of-door environment are higher than that found in indoors. The chief beginnings of the high indoor Ozone concentration are the photocopy machines, optical maser pressmans, electrostatic air cleaners and x-ray generators, ( Yocom, 1982 and Wadden, 1983 ) . These beginnings develop electrostatic Fieldss that can bring forth extremely toxic concentrations of ozone in air. Exposing to low concentration degrees of Ozone can do oculus annoyance, ocular perturbations, concerns, giddiness, oral cavity and pharynx annoyance, thorax hurting, insomnia, breath shortness and coughing ( Sittig, 1991 and Apte et Al. 2007 ) , where exposure to high degrees of ozone can cut down lung map or respiratory jobs, such as asthma or bronchitis, ( Bates, 1989 ; EPA, 2008 and ASHRAE, 2009 ) Hydrocarbons Most of the indoor hydrocarbons beginnings are consequences from the different housework stuffs such as widows, oven, drain, vesture cleaners, pigment dissolver and human usage stuffs such as deodourants, shaving picks, hair sprays and air refreshers sprays. The indoor hydrocarbons degrees reach high degrees when housework is in advancement, Meyer ( 1983 ) . The indoor cookery gas ( largely Propane gas ) is considered besides a major beginning of the indoor hydrocarbons which may consequences in serious fire accidents or decease due to deficient care or checking for the gas burner and cookery equipment, Meyer ( 1983 ) . Particulate affair ( PM ) Particulate affair ( PM ) can be found solid and/or liquid droplets atoms suspended in air. Particulate affair can be generated from adult male made ( fossil fuels burning and mechanical procedures ) or natural ( vents, dust storms, and forest and grassland fires ) , ASHRAE ( 2009 ) . There are many beginnings of the indoor atoms such as pets, gas ranges, and baccy fume. Atoms classified harmonizing to its size as all right atoms are those whose size is smaller than 2.5 I?m and harsh atoms are those which are larger than 2.5 I?m. Heinrich and Slama ( 2007 ) argued that the all right atoms are the major menace beginning that affects the kids wellness, where exposing to ticket atoms can consequences in cardiac and respiratory jobs, ( Dockery et al. , 1993 ; Dockery and Pope, 1994 ; Pope et al. , 2002 ; Wu et al. , 2005 and Gilliland et al. , 2005 ) . The PM metals constituents are a major beginning that involves in the development of pneumonic, cardiovascular and allergic diseases, Sch warze et Al. ( 2006 ) . Exposure to high degrees of all right atoms causes wellness jeopardies such as bosom diseases ; respiratory diseases ; altered lung maps, particularly in kids, and lung malignant neoplastic disease and decease, EPA ( 2008 ) . Bioaerosols Parameters Fungi, viruses, bacteriums, fungous and bacteria spores, pollen and allergens are types of the microbiological indoor particulate contaminations. The major beginnings of these contaminations are human, animate beings and workss and it can be found anyplace these beginnings are available, Meyer ( 1983 ) . Due to the deficient care of the HVAC system parts ( capacitors, chilling spirals, canals and drainage pans ) it can be another beginning of taint by promoting the proliferation of the bugs, ( Wark and Warner, 1981 and Samet et al. , 1991 ) . The concentrations of the indoor bugs are higher than that in the out-of-door environment due to the edifice stringency and the beginning handiness. Dust Dust is one type of the solid particulate contaminations. ASHRAE ( 2009 ) defines dust as â€Å" solid atoms projected into air by natural forces such as air current, volcanic eruption, temblors, or by mechanical procedures including suppression, crunching, destruction, blasting, showing, boring, shoveling and sweeping † . Dust immigrates from exterior to inside environment by infiltration air through the edifice ‘s cleft, uncertain Windowss and doors and through the airing system. Dust has wellness effects on people with ultra-sensitive lungs such as people with asthma, immature kids and aged people. Dust causes uncomfortableness for people and amendss home furniture and family equipment. Olfactory properties Indoor olfactory properties are originating from resident ‘s organic structure and their indoor activities such as smoke, cookery, refuse, sewerage and industrial procedures. The human organic structure usually dissipates around 200 types of chemicals which are responsible for the human olfactory properties, ( Meyer, 1983 ) . Olfactory properties do non hold any major effects on the resident ‘s wellness, but it causes discomfort esthesis to the residents which make it as a mark of the hapless indoor air quality. During this survey, the CO2 contamination will be studied to look into the indoor air quality inside Kuwaiti ‘s schoolrooms. The indoor concentration of C dioxide ( CO2 ) has frequently been used as a alternate for the airing rate per resident, ( Lee and Chang, 1999 and Daisey et al. , 2003 ) , where supplying good airing rates with sufficient sums of fresh air can thin and reduces the concentrations degrees of indoor air pollution generated by the different indoor pollutants beginnings. International and Kuwait Indoor Air Quality Standards and Regulations Since the last decennary, research workers were interested to look into the indoor air pollution for different indoor environments and the contamination beginnings to bespeak the acceptable indoor concentration degrees for these pollutants. As a consequence of these researches, many IAQ criterions and ordinances have been developed and established by different organisations indicates the recommended acceptable concentrations degrees for these indoor pollutants. A sum-up of the common indoor air pollutants criterions in ppm ( unless otherwise specified ) are given in Table 3.1. Since people spend most of their times in indoor environments in edifices, these edifices are expected to be good designed to non endanger the residents ‘ wellbeing and wellness. Residents ‘ have good cognition of the different types of the indoor pollutants and it is wellness jeopardies on human, but there is still one facet which is the quality of the air inside the edifice envelope and whether it is equal or unequal which may non hold a menace to residents ‘ wellness. Due to the energy crisis of the 1970s, tighter edifices designs with low air exchange ( fresh air ) with outside environment have been constructed in order to salvage energy costs. Indoor air recirculation airing scheme has been used for constructing airing intents. Although important energy nest eggs was accomplished, research workers reported residents ‘ complains due to a composite and even disenabling syndromes. These syndromes are recently defined as ill edifice syndrome ( SBS ) and were linked to the pollution of the inside air and the degree of the airing. Unacceptable indoor air quality ( IAQ ) conditions may happen in 30 % of the new edifices ( WHO, 2000 ) and may do diverse symptoms and unwellnesss that affect the residents ‘ wellbeing and consequences to increase residents ‘ productiveness lost and work absenteeism. These symptom syndrome which referred to as SBS, may take to important work clip lost and medical costs that affects the national economic system. The ill edifice syndrome ( SBS ) can be identified by the undermentioned typical symptoms such as concern ; chest stringency ; lethargy ; dry thorax ; stuffy nose ; lost of concentration ; dry tegument ; blocked, runny an scabies olfactory organ and lacrimation or antsy eyes. Constructing ill syndrome ( SBS ) and the edifice related unwellness ( BRI ) are non needfully to be the same, where the BRI symptoms such as disease, coryza and asthma are more acute than SBS symptoms in the edifices, Singh ( 1996 ) . Indoor Air Quality ( IAQ ) in Schools Schools are the most of import indoor environments that kids spend most of their times besides places. It is good documented that IAQ jobs in schools and other edifices types commercial and residential occurred during the 1970s oil episodes. Ventilation in these edifices has decreased to salvage energy by depending on the indoor recycled air inside the occupied zone. Children breathe higher volumes of air relative to their organic structure weights which make them more susceptibleness to some environmental pollutants than grownups, ( Faustman et al. , 2000 and Landrigan, 1998 ) . Poor IAQ in the schoolroom could hold negative impacts on kids ‘s acquisition and public presentation, which may hold both immediate and womb-to-tomb effects, for the pupils and for society ( Mendell and Heath, 2005 ) . Many research workers investigated IAQ jobs in schools around the universe, where these probes were conducted frequently for a specific individual indoor air pollutant or a combination of pollutants ( GAO, 1995 ) . In schools, pollutant emanations can happen in many topographic points within the school envelope such cafeterias, swimming pools, scientific discipline labs ( frequently without fume goons ) and computing machine suites. IAQ jobs can consequences besides from the edifice design, building stuffs, type of the HVAC units and the deficiency of care of these units, and crowded schoolrooms. The undermentioned literature is some illustrations of the surveies conducted in schoolrooms around the universe to look into the effects of the different indoor pollutants on the pupil ‘s wellness and public presentation. The NO2, TVOC, methanal, PM10 and asbestos dust concentrations were measured by Cavallo et Al. ( 1993 ) in 10 of course ventilated schools and seven air-conditioned office edifices in Italy. The findings of this survey suggested that the mean NO2, PM10 and asbestos dust concentrations were the same indoors and out-of-doorss in all schools. The effects of generated pollutants from gas warmers on kids in 41 schoolrooms in Australia were studied by Pilotto et Al. ( 1997 ) . A important relation was found between the indoor NO2 concentration and the absences of the pupils from school. The writers reported that strong grounds was found between the association of NO2 concentration degrees and the pupil ‘s sore pharynx, balls and absences from school even at these low degrees. Lee and Chang ( 2000 ) measured and compared the indoor and out-of-door comparative humidness ( Rh factor ) , CO2, SO2, NO, NO2, PM10, HCHO concentrations and entire bacterium counts in five air-conditioned or of course ventilated schoolrooms in Hong Kong. The purpose of this survey was to look into whether the mensural indoor concentration degrees are complied with the Hong Kong criterion. In a survey by Daisey et Al. ( 2003 ) reviewed and analyzed the literature of the go outing IAQ, airing and indicated the edifice wellness jobs information related to the school edifice. The mensural airing and CO2 concentrations showed that many of the schoolrooms were have unequal airing. They suggested that although degrees of the mensural indoor pollutants concentrations ( HCHO, VOCs and bioaerosols ) were lower than that recommended by criterions and guidelines, exposures to pollutants in schools are associated with allergic reaction, asthma, and SBS symptoms In Denmark, Meyer et Al. ( 2004 ) conduced a cross-sectional epidemiological survey included 1053 school kids aged 13-17 old ages, in 15 school edifices utilizing questionnaire about the edifice related symptoms and wellness facets effects on the pupils exposure some to indoor pollutants. In this survey the room temperature, CO2, comparative humidness degrees were measured, the dust from the floors, air, airing canals during school twenty-four hours were collected and constructing features including mold infestation were assessed. The writers reported there is no positive association between building-related symptoms and the wet of the air and growing of casts in the school edifices. The writers concluded that cast exposure is secondary beginning and non a chief beginning to either asthma, hay febrility, recent air passage infection, or psychosocial factors. A field survey included 358 pupils in traditional and portable mechanical ventilated schoolrooms in 22 primary and secondary schools conducted by Shendell et Al. ( 2004 ) to look into the consequence of the difference between the outdoor and indoor CO2 concentrations and the pupil absence in Washington and Idaho, USA. The short-run CO2 concentrations were higher in more than half of the schoolrooms. The writers found that a 1000 ppm addition in the dCO2 will diminish the one-year mean day-to-day attending of the pupils by 0.5-0.9 % , matching to relative10-20 % addition in the pupil ‘s absence. In a critical scientific reappraisal about the grounds for the direct association of the indoor pollutants and thermic conditions on the pupils ‘ public presentation and attending in schools, Mendell and Heath ( 2004 ) concluded that exposing to indoor microbic and chemical pollutants beginnings in schools can be linked to increased school absenteeism, asthma, and allergic reaction in kids and grownups. In eight schools edifices in France, which were either of course or automatically ventilated, Blondeau et Al. ( 2005 ) carried out a field survey to mensurate the outdoor and indoor pollution in these edifice. In this field study the writers continuously monitored the outdoor and indoor gaseous pollutants ( Ozone, NO and NO2 ) , and airborne atom pollutants in add-on to the indoor humidness, temperature, CO2 concentration for two 2-week periods. The findings of this survey shows an acceptable No and NO2 outdoor/indoor concentrations ratio, where the outdoor/indoor Ozone concentrations ratio was high and was affected by the out-of-door environment. Writers argued reported that â€Å" the more air-tight the edifice envelope, the lower the Ozone ratio occurred † . They besides found the tenancy is strongly influences the indoor concentration degree of the mensural airborne atoms when the edifices were occupied. In parallel categories of 10-year-old kids, Wargocki et Al. ( 2005 ) studied and measured the impact of the IAQ by increased airing on the kids ‘s larning public presentation. In appropriate lessons each hebdomad, the kids ‘s usual instructors administered parallel public presentation from reading to mathematics undertakings were administrated by instructors to the kids during a school hebdomad period. The writers found that if the airing rate increased from 5 to 10 l/s, a important betterment by ore than 15 % in the public presentation of school work is achieved. In a field survey conducted in 64 simple and in-between school schoolrooms in Michigan, USA, Godwin and Batterman ( 2007 ) , monitored and examined the Indoor air quality ( IAQ ) parametric quantities to measure the degrees of different indoor pollutants ( CO2, VOCs and bioaerosols ) , the emanation beginnings, comparative humidness, temperature and the airing rates over one school hebdomad. During this survey the writers completed a comprehensive and the measurings were used to look into the differences in air quality degree within and between schools. It was found that in many of the tested schoolrooms the CO2 concentrations are higher than the standard degree ( 1000 ppm ) which indicates unequal airing rates, where the degrees of the mensural indoor pollutants were low to chair concentrations. Ventilation Ratess and Energy Consumption in School Ventilation procedure is supplying sums of out-of-door air ( fresh air ) from the outside environment to the inside infinites or zones via flow through of course agencies ( unfastened doors and window ) or automatically agencies ( fans and HVAC systems ) or by infiltration through the edifice clefts. The chief thought of the airing procedure is to supply the comfort and wellness conditions of the residents by equilibrating the thermic comfort conditions and thining the concentrations of the indoor pollutants within the occupied zone envelope. The ingestion of the energy in the airing procedure in edifices is due to the usage the automatically ventilation systems to thermally conditioning the airing air by chilling, warming, dehumidification or humidification procedures or utilizing airing fans. The capacity of the energy ingestion by these systems is relative straight to the addition of the sum of the airing air needed. The airing procedure is guided by the international criterions and ordinances such as ASHRAE 62 criterion by stipulating the minimal airing rates that can run into the resident ‘s comfort and wellness conditions to keep their public presentation and productiveness, while salvaging the energy used. Due to Kuwait clime is characterized as hot and dry desert clime, the usage of the HVAC systems is indispensable in all edifice most of the twelvemonth. Air-conditioning in Kuwait consumes 45 % of the one-year energy production ( 21 G.kWh ) with one-year cost of about KD 0.7 billion, ( MEW-R6, 2010 and MEW, 2010 ) . In Kuwait there is 540 school edifices consists of 14426 schoolrooms occupied by 360634 pupils with an mean ratio of 25 pupils per schoolroom, MOE ( 2009 ) . The figure of schools is subjected to be increase by 10 % annually, MOE ( 2009 ) . Since the beginning of 1990 ‘s, the school edifices in Kuwait were extensively constructed or renovated. Air-conditioning systems were installed in those edifices to supply comfy thermic and wellness conditions. The control of those systems is non under the direct control of the pupils, and this may hold a negative consequence on the pupil comfort and wellness in the schoolroom. These schools consume about 10 % of the state one-year energy production ( 2.1 G.kWh per twelvemonth ) costs about KD 60 1000000s with a day-to-day rate of 16 kWh per pupil and one-year addition of 5 % , MEW ( 2009 ) . The ASHRAE criterion 62 ( 2004 ) for airing demands is considered by MEW-R6 ( 2010 ) codification for the different types of edifices and infinites. Harmonizing to this criterion a minimal airing rate of 7.5 L/s ( 15 ft3/min ) per resident in schoolrooms is recommended with a typical occupant denseness of 33 individuals per 90 M2 ( 1000 ft2 ) and ceiling tallness of 3 m ( 10 foot ) . The current ASHRAE criterion would necessitate an air exchange rate of about 3 air alteration per hr ( ACH ) for schoolroom. Sing to the air alteration rates in hr, the ministry of electricity and H2O recommended an air alteration of 0.5 ACH for schoolrooms for energy economy demands, MEW-R6 ( 2010 ) . The indoor air quality conditions in schoolrooms have to be earnestly considered because pupils are still physically developing, where hapless indoor air quality conditions could impact the pupils ‘ and staff ‘s comfort, wellness and may indirectly impact their acquisition and public presentation and productiveness – this may hold damaging effects on them and the society ‘s hereafter. Ventilation rates and Student ‘s Performance and Productivity Through the literature there are few surveies conducted to look into the consequence of the different airing rates on the pupil ‘s and staff ‘s school work public presentation and productiveness in schoolrooms. Myhrvold and Olesen ( 1997 ) conducted a field survey in 35 Norse schoolrooms to mensurate the pupils ‘ concentration by mensurating their reaction times with different airing rates. They found that by increasing the airing rate per individual from 4 L/s to 12 L/s, the pupils ‘ reaction times were 5.4 % less ( i.e. faster ) . In three public presentation trials used by Ito et Al. ( 2006 ) and Murakami et Al. ( 2006 ) in Nipponese schoolrooms, research workers found that with an addition in airing rate from 0.6-5 L/s the public presentation was improved 5.4 % ; 8.7 % and 5.8 % severally. Wargocki and Wyon ( 2006 ; 2007a and B ) investigated the impact of increasing the airing rate on the public presentation of 10 old ages old school kids with analogue of public presentation undertakings. The writers found that increasing the airing rate from 5 to 10 L/s, the school work public presentation will improved by 15 % and do a noticeable kids ‘s school public presentation and acquisition. In two UK schoolrooms, it was found that the students ‘ work rate increased by 7 % in the mathematical trials of add-on and minus by increasing the supplied fresh air from 0.3-5 to 13-16 L/s, ( Bako-Biro et Al, 2007 ) . Discussion Through the presentation of the indoor air quality literature reappraisal in this chapter, it can be shown that the importance of look intoing quality of the indoor air in the different occupied zones, particularly schoolrooms in schools, to bespeak the pollution beginnings and the degree of the different pollutants that may happen in schoolrooms. The necessity to regularly look into the indoor air quality inside the schoolrooms is due to the high denseness of pupils in schoolrooms and the long period of exposure for the different pollutants beginnings which may earnestly impact the pupil ‘s and staff ‘s comfort and wellness and consequences in serious wellness jobs that can increase the absence from school and increases the public presentation and productiveness losingss. These attendant wellness jobs can impact the national economic system by increasing the national wellness attention disbursals and lost disbursals due to the loss public presentation and productiveness in schools. Investigating the indoor air quality conditions inside schoolrooms is an expensive and potentially debatable issue because it is a map of different factors such as the edifice stuffs, equipment, furniture and HVAC systems where all of them are changing as a map of clip exposure and airing. The rate of airing inside any occupied zone can be a step for the quality of the indoor air. The adequately airing rate can be an index for inside environment, where during the literature many research workers reported that inadequate ( low ) airing rate indicates hapless indoor air quality and frailty versa. During this survey, the airing rates measurings inside the schoolrooms can be inferred by the C dioxide measurings, where the indoor concentration of C dioxide ( CO2 ) has frequently been used as a alternate for the airing rate per resident, including in schools. Lee and Chang ( 1999 ) and Daisey et Al. ( 2003 ) stated that the

Reports of Abbot Dashan and Father Du Jarric essays

Reports of Abbot Dashan and Father Du Jarric essays A number of kings may have ruled in 17th century Asia, yet they differed significantly in their treatment of citizens and captives. Two historic recordsone written by the influential Chinese Buddhist Abbot Shilian Dashan about self-proclaimed King Minh Vuong in 1695, and the second compiled by Father Pierre Du Jarric during the early 1600s on Akbar or Great Mogulclearly demonstrated how varied these kingdoms could be. In 1695 King Minh Vuong invited Abbot Dashan to his Vietnamese Kingdom of Dang Trong, or what the Europeans called "Cochinchina," to establish the principles of the school of Zen Buddhism. After an arduous voyage, made worse by the claustrophobic quarters shared with merchants and traders, the multi-storied vessel arrived at its destination. It did not take long for the abbot to recognize that not all was peaceful and abundant in this land. Several old men, unkempt and with blackened teeth, came up to the boat as soon as it arrived. However, they were fearful and did not come aboard. This was the responsibility of the king's officers only. Later, much to the abbot's embarrassment and uneasiness, ten marines physically carried him off the ship. They headed to the Royal Inspectorate's war vessel, which was rich with incense, gold boxes and other adornments. Meanwhile, King Minh Vuong stayed in his palace. He would wait for the abbot to come to him, rather than the The next day, Abbot Dashan discovered why he only saw old men, women and children in the villages. Any able-bodied man over 16 had to leave his family behind until the age of 60. All younger males in good health were required to be soldiers in the king's army and do whatever he demanded. They fought whenever there was a war and worked for the state in other capacities in times of peace. For example, King Minh Vuong sent 1,000 soldiers to build Dashan's new house. Many famil...

White Oleander Essays - White Oleander, Astrid Peth, Claire Bennet

White Oleander Essays - White Oleander, Astrid Peth, Claire Bennet White Oleander White Oleander, a dramatic fiction by Janet Fitch, was published by Little, Brown and Company in Boston. The story is about a mother and daughter, Ingred and Astrid have a very unusual relationship. Ingred loves her daughter but never asks her what she thinks so therefore doesn't know her daughter too well. Such as she does not know of her daughter's yearning for a father. Ingred makes it very clear that she will not allow herself to get close to a man. She is a very brilliant, beautiful poet, who is adored by a man named Barry Kolker. He goes to all of her readings, and asks her out each time. One of the times Barry invites her to go to the Gamelan, an orchestra. Loving the Gamelan, she accepts. Her and Astrid join Barry, and they begin talking more. They start going out more, but each time she makes and stands by regulations, such as he will invite her to eat after an event where they had not planned on eating and she will refuse, because she doesn't like to get attached to men, and doesn't want to spend anymore time than she had already allotted. All of a sudden, her rules start diminishing. One time, there was a knock at her door, and it was Barry. She thought to herself, 'how dare he just come without an invitation?'. When she opened the door (a knife in her hand), he had a bottle of wine, and bag of something that smelled good. To Astrid's surprise she did something least expected. She invited him in. One night Barry said he would be over to her house at 9 and never showed. So the next day, Ingred showed up unannounced at Barry's and she went inside and they made love. Immediately after, he told Ingred she had to leave because he had a date coming. She wanted to seek revenge. She started showing up at every place he was at. She broke into his house. He tried to go to her house and make her stop the nonsense. He tried forcing his way in her house, and she stabbed him in the hand. He left, and the next day she went to his house, where she found he had changed the locks. She broke in and placed white oleanders in his milk, oy ster sauce and cottage cheese, and one in his toothpaste. She made an arrangement of white oleanders on his table, and scattered blooms on his bed. A police officer came to Ingred's house, and told her that Barry is accusing her of breaking and entering, and trying to poison him. She calmly stated that Barry is angry with her. She broke up with him and that he couldn't get over her. Ingred and Astrid took trip to Tijuana and Ingred bought a bottle of medicine called, DMSO, which helps drugs absorb through your skin (DMSO helps nicotine patches work), and uses that to poison him. He dies. Ingred is eventually placed in jail, leaving Astrid to jump from foster home to foster home. Her first foster home is with a mother named Star. Star is a busty, and leggy, ex-coke addict turned Christian. Star has a boyfriend named Ray, and Astrid falls in love with him. Astrid, 13, has an affair with the 40-something Ray. Star gets jealous of their friendship and gets suspicious. One day, Star comes in, in a drunken rage and shoots Astrid. Astrid is immediately removed and placed in a second home, the home of Ed and Marble Turlock. At this home, she was treated like a slave. She was forced to clean and baby-sit, and was never shown any affection, and was never introduced to anyone. Astrid makes friends with a black neighbor, named Olivia Johnston, who the prejudiced Marble condemns a hooker. When Marble finds that Astrid is friends with her, Marble beats her up, and she once again gets moved, which she finds out at school, with her bags already packed for her, and no chance to say good-byes. The third house, was a big, beautiful estate. Amelia, the foster mother took in girls as slaves, and when she would leave, she

Gustav Kirchhoff and Kirchhoffs Laws for Electrical Circuits

Gustav Kirchhoff and Kirchhoff's Laws for Electrical Circuits Gustav Robert Kirchhoff (March 12, 1824–October 17, 1887) was a German physicist. He is best known for developing Kirchhoff’s laws, which quantify the current and voltage in electrical circuits. In addition to Kirchhoff’s laws, Kirchhoff made a number of other fundamental contributions to physics, including work on spectroscopy and blackbody radiation. Fast Facts: Gustav Kirchhoff Full Name: Gustav Robert KirchhoffOccupation: PhysicistKnown For: Developed Kirchhoffs laws for electrical circuitsBorn: March 12, 1824 in Kà ¶nigsberg, PrussiaDied: October 17, 1887 in Berlin, GermanyParents’ Names: Carl Friedrich Kirchhoff, Juliane Johanna Henriette von WittkeSpouses Names: Clara Richelot (m. 1834-1869), Benovefa Karolina Sopie Luise Brà ¶mmel (m. 1872) Early Years and Education Born in Kà ¶nigsberg, Prussia (now Kaliningrad, Russia), Gustav Kirchhoff was the youngest of three sons. His parents were Carl Friedrich Kirchhoff, a law counselor devoted to the Prussian state, and Juliane Johanna Henriette von Wittke. Kirchhoff’s parents encouraged their children to serve the Prussian state as best as they were able. Kirchoff was an academically strong student, so he planned to become a university professor, which was considered a civil servant role in Prussia at that time. Kirchhoff attended Kneiphofische High School with his brothers and received his diploma in 1842. After graduating high school, Kirchhoff began studying in the Mathematics-Physics department at the Albertus University of Kà ¶nigsberg. There, Kirchhoff attended a mathematics-physics seminar from 1843 to 1846 developed by the mathematicians Franz Neumann and Carl Jacobi. Neumann in particular had a profound impact on Kirchhoff, and encouraged him to pursue mathematical physics – a field which focuses on developing mathematical methods for problems in physics. While studying with Neumann, Kirchhoff published his first paper in 1845 at age 21. This paper contained the two Kirchhoff’s laws, which allow for the calculation of the current and voltage in electrical circuits. Kirchhoff's Laws Kirchhoff’s laws for current and voltage are at the foundation of analyzing electrical circuits, allowing for the quantification of current and voltage within the circuit. Kirchhoff derived these laws by generalizing the results of Ohm’s law, which states that the current between two points is directly proportional to the voltage between those points and inversely proportional to the resistance. Kirchhoff’s first law says that at a given junction in a circuit, the current going into the junction must equal the sum of the currents leaving the junction. Kirchhoff’s second law says that if there is a closed loop in a circuit, the sum of the voltage differences within the loop equals zero. Through his collaboration with Bunsen, Kirchhoff developed three Kirchhoff’s laws for spectroscopy: Incandescent solids, liquids, or dense gases – which light up after they are heated – emit a continuous spectrum of light: they emit light at all wavelengths.A hot, low-density gas produces an emission-line spectrum: the gas emits light at specific, discrete wavelengths, which can be seen as bright lines in an otherwise dark spectrum.A continuous spectrum traversing through a cooler, low-density gas produces an absorption-line spectrum: the gas absorbs light at specific, discrete wavelengths, which can be seen as dark lines in an otherwise continuous spectrum. Because atoms and molecules produce their own unique spectra, these laws allow for the identification of atoms and molecules found in the object being studied. Kirchhoff also performed important work in thermal radiation, and proposed Kirchhoff’s law of thermal radiation in 1859. This law states that the emissivity (ability to emit energy as radiation) and absorbance (ability to absorb radiation) of an object or surface are equal at any wavelength and temperature, if the object or surface is at static thermal equilibrium. While studying thermal radiation, Kirchhoff also coined the term â€Å"black body† to describe a hypothetical object which absorbed all incoming light and thus emitted all of that light when it was maintained at a constant temperature to establish thermal equilibrium. In 1900, the physicist Max Planck would hypothesize that these black bodies absorbed and emitted energy in certain values called â€Å"quanta.† This discovery would serve as one of the key insights for quantum mechanics. Academic Career In 1847, Kirchhoff graduated from Kà ¶nigsberg University, and became an unpaid lecturer at Berlin University in Germany in 1848. In 1850, he became an associate professor at Breslau University and in 1854 a professor of physics at Heidelberg University. At Breslau, Kirchhoff met the German chemist Robert Bunsen, after whom the Bunsen burner was named, and it was Bunsen who arranged for Kirchhoff to come to Heidelberg University. In the 1860s, Kirchhoff and Bunsen showed that each element could be identified with a unique spectral pattern, establishing that spectroscopy could be used to experimentally analyze the elements. The pair would discover the elements cesium and rubidium while investigating the elements in the sun using spectroscopy. In addition to his work in spectroscopy, Kirchhoff would also study blackbody radiation, coining the term in 1862. His work is considered fundamental to the development of quantum mechanics. In 1875, Kirchhoff became the chair of mathematical physics at Berlin. He later retired in 1886. Later Life and Legacy Kirchhoff died on October 17, 1887 in Berlin, Germany at the age of 63. He is remembered for his contributions to the field of physics as well as his influential teaching career. His Kirchhoffs laws for electrical circuits are now taught as part of introductory physics courses on electromagnetism. Sources Hockey, Thomas A., editor.

Earth's atmosphere, Clouds, and Air pressure and Wind Assignment

Earth's atmosphere, Clouds, and Air pressure and Wind - Assignment Example It keeps the temperature balanced within 24 hours as well. At different temperatures, the atmosphere is further subdivided into layers beginning from the Earth’s surface where troposphere lies between 7 to 14 kms followed by the stratosphere reaching the 50-km altitude. This layer is conducive for airplanes due to stability and with increasing temperature, only minimal amount of water vapor and other components may be detected. On top of the stratosphere is the mesosphere about 30 km in thickness which, due to unstable winds and temperature, experiences a certain degree of coldness. Within 80 to 85 kms from the ground begins the region of the thermosphere that spans a width of about 560 km or greater where it is possible for radio waves to be reflected during communication via radio system. Types of Clouds Clouds are generated every time the atmosphere becomes saturated with water vapor to the point they are unable to contain it in excess that phase change from vapor to liquid for water necessarily takes place during condensation stage of the water cycle. These clouds are massive by several millions of tons in weight and are classified based upon their physical appearance and altitudes. On the basis of the way they look in the sky, stratus clouds refer to the type which may be seen as flat sheets among low to high-level clouds. Another type under this classification are the cumulus clouds which are puffy, lumpy, or wavy and when enormous in size could form into towering vertical clouds with a potential to generate thunderstorm. Cirrus clouds, the third type, are known to be high and thin and cold at high levels, being made of ice crystals rather than water droplets. With reference to how high they could get from the ground level, clouds come in five types namely – high-level clouds, medium-level clouds, low-level clouds, moderate-vertical clouds, and towering-vertical clouds. It is quite interesting to find out that heavy rain, snow showers, and s now can be created with both the towering-vertical clouds and the moderate-vertical clouds. Air Pressure and Wind Systems When air exerts force on a particular area of the Earth’s surface due to the air’s weight then an atmospheric pressure emerges. This pressure increases as the layer of air becomes thick and this occurs at low altitudes whereas high places encounter low atmospheric pressure for having thin air around. A mercury barometer is the device used to measure air pressure in inches or millimeters. Wind, compared to still air, is identified with gases in motion and in our living planet, the mere flow of air is called wind. A ‘solar wind’, however, is caused by the flow of gases or particles from the sun in the outer space. Winds go by different names depending on their speeds and how long they stay on a particular spot. Gusts, for instance, are known as short bursts of fast winds, breeze for the light ones, whereas squalls are those with great str ength that last in a minute. Typhoon, hurricanes, storms, tornadoes, and cyclones are some other names given according to the wind’s nature of existence and they normally take place with high pressure differences beyond 200 miles per hour.

The Christina Commonwelath - analysis and criticism to this little book by John Eliot - Essay Example (Zakai, 133-151) Perhaps more than anything else, Eliot’s work and its concurrent ideology denounced the interregnum of the Crown with the result that three years following its publication The Christian Commonwealth was banned in England. (Holstun, 128-153) Although Eliot’s work takes a definite position with respect to Puritan ideology of the perfect state it is prefaced by a position against the monarchy. By taking this position in the preface to The Christian Commonwealth Eliot introduces a position against the interregnum of the Crown in such a way that is far more controversial than the Puritanical theocracy embodied in the main part of his book. Eliot’s states his opposition to the monarchy in his preface as follows: â€Å"Much is spoken of the rightful Heir of the Crown of England, and the unjustice of casting out the right Heir: but Christ is the only right Heir of the Crown of England, and all other Nations also.† (Eliot) In his preface Eliot quotes the scriptures at various intervals to support his contention that the best model of human ordinance and government is to be found in the Bible rather than by reference to earthly state nations. The preface is laden with Puritan theocracy and puts forth the concept that it is God who truly governs and protects those who believe in him. Eliot goes on to urge that true guidance should come from God and urges as follows: â€Å"I do beseech those chosen, and holy and faith Saints, who by Councils at Home, or by Wars in the field, have fought the Lords Battels against Antichrist, and have carried on the Cause of Christ hitherunto, That you would now set the Crown of England upon the head of Christ, whose only true inheritance it is, by the gift of his father (1) â€Å" Let him be your JUDGE, let him be your LAW – Giver, Let him be your KING. Take the pattern and

Private Life Should Mean What It Says Essay Example | Topics and Well Written Essays - 4000 words

Private Life Should Mean What It Says - Essay Example It was therefore not considered to be offensive. Later in October of 1999 when he was asked to declare the organizations with which he was associate, among them he listed the House of Roissy, which did such activities as fire acts and the merchandising of products that were connected with domination bondage and sadomasochism. It was also his acknowledgement that he performed in fetish and hedonist clubs but contended that such would not bring his employers to disrepute. The Assistant Chief of Probation considered this activity as unsuitable for a probation officer. The Human Resource Officer had no issue with the fact that the employee had another paid job outside his normal employment but whether or not, given that he was a public servant and a member of the criminal justices system, working with sexual offenders and several other groups that were considered vulnerable, the employees activities during his private time were commensurate with the role that he was playing in the societ y and if the public could trust him. This is despite the fact that they had not been offended by his performance but rather by the fact that he was expressing himself in a way that would otherwise be considered offensive by the victims of the people he was dealing with. The employee was dismissed and his dismissal was upheld when he appealed. It was the view of both disciplinary panels that the probation service had the responsibility to the public to show them that it had integrity and so did its officers and that if the public knew the activities that this particular employee was engaged in, it could ruin the reputation of the service. This is based on the fact that probation in itself was aimed at reforming the people in the society who were now considered a... This report stresses that the law of unfair dismissal is a part of private and not public law. So are many regulations that government employment, in both public and private sector. While there are regulations that may be in the interest of the public, private remains exactly that, private. There are many principles of public law that have been imported into the regulations that govern the relationship between an employee and his employer because of the rules of natural justice. This is mostly because these two share several common and essential features especially in the review of decisions and the manner in which such decisions are made and reached. This paper makes a conclusion that given the inevitable compromise and balance between work life and private life and the commitments involved in both particularly in matters relation to family issues, it is necessary to strike a balance between what is significant to the reputation of the employers or the duties of an employee and what is not. The reality of the circumstance that surrounds every case has to be considered. What should also be reviewed are the terms and conditions of employment, be they express or implied. This is because letting employers determine what affects their reputation or firm would amount to giving them permission to arbitrarily termination employment contracts on the basis of factors which they consider to be in contravention of the terms of their employment while it is possible they are just negatively stereotyped towards certain activities or beliefs of the employee.

At-risk students attitudes toward schooling as related to achievement, Essay

At-risk students attitudes toward schooling as related to achievement, attendance and bahavior - Essay Example ed on the SAAS-R that records students attitudes about feelings about school, teacher relationships, the ability to do well in school, the potential for good grades and engagement in school activities and actual academic achievement, as defined by performance on the Kentucky K-Prep instrument. The study will also measure the relationship between student feelings about self and school and other non-academic factors, such as attendance and the number over recorded behavioral infractions. The academic success of a student depends on numerous positive and negative factors. An overabundance of negative factors present in a student’s life may place them at-risk for facing a number of difficulties such as academic failure, withdrawing from school, and exhibiting certain behavioral problems that my result in a lower quality of home and school life. These risk factors can include ethnic or minority status, low socio-economic standing, and family level of education attainment. Another significant risk factor involves whether or not the student exhibits any physical, behavioral, or emotional disabilities. All of these dynamics may combine to compromise the student’s chances of receiving a quality education in a free and public school. It is also important to consider other potential barriers to academic achievement. The risk factors here involve a student’s lack of motivation, self-perception, and the interaction that takes place between teachers and other school staff. Rollins and Valdez (2006) found that student perceptions of how they will perform in school determine their academic success. Perception is defined to include all processes associated with the recognition, transformation, and organization of sensory information (Little, 1999). The perception theory defines perception as images that exist where and when the mind perceives them (Carr, 1918). Carr proposed that images are not the whole reality of what is seen, but reality is duration, and the

During this period, the dresses, which were worn by individuals, and the materials utilised in making the accessories which they wore, defined a social class which an individual belonged to. The queen of France developed elaborate gowns that she used to create her persona during the 19th century. The aspects of creating a persona through dressing and accessories resulted in individuals wishing to connect to the queen by adopting similar dressing codes. These gowns became the cultural norm for the women of higher social class in France during the early 19th century. Through the fashion, the queen was able to articulate herself and set precedence for other monarchs, which were relatively common during that period. It became increasingly popular for monarchs to have an official dress code, which mainly resulted from common fashions. Paris has been highly associated with fashion because of the early development in fashion within the city. Fashion magazines from different countries commonly sent editors to fashion shows in Paris and the fashion stores in order to gather materials, for writing about fashion. Many people commonly seem to copy the well, developed designs that have been established and Paris offered exquisite designs of many products ranging from clothing, shoes and even ornaments. The spread of French fashion was enhanced through these magazines, which individuals in other parts of the world relied on to make decisions regarding fashion products. As the popularity of fashion magazines increased, many of them began including photographs which became influential on the future designs adopted in different regions of the world. The magazines were greatly sought after and had a noteworthy consequence on

Analysis of Alcan case study Example | Topics and Well Written Essays - 1750 words

Analysis of Alcan - Case Study Example There was a wide spread of perception that it was hard to implement changes and that communication was poor. The management wanted to impose change in the organization. They thought about three options for change but only implemented two of them. Team working was introduced and later on, there were structural changes. The senior managers and the workers said that team working produced results in terms of staff satisfaction; effectiveness of the work organization and productivity but the middle level and technical staff disagreed with this. They felt that there was a lot of dissatisfaction in team working change can be an expensive and difficult process and fewer problems will be experience in less drastic change program, but even then it is not something to be contemplated without care. Lynemouth production began its production in 1972. Work organization was fairly conventional with each group of workers being responsible to a supervisor who dealt with all day-to-day production matters such as the allocation of tasks, granting of holiday and shifts. Majority of workers were production operatives and craft workers who belonged to trade union. The Management wanted to impose change by insisting on the application of parts of existing agreement rather than involving the unions. The employees reported lack of consultation by management and this contributed to a growing sense of worker dissatisfaction. This in turn adversely affected the quality of production. According to Fredrick Taylor, he thought by scientifically analysing work, the "One Best Way" to do it would be found. He is most remembered for his time and motion study. He would break a job into its component parts and measure each to the second. Taylor believed that contemporary management was amateurish and should be studied as a discipline, that workers should cooperate with management and hence would not need Trade Unions. He believed that the best results would come from the partnership between a trained and qualified management and a cooperative and innovative workforce. Each side needed the other. This approach would have been an awkward one because, the unio n is the workers representative and they should be consulted to contribute ideas toward the change. According to Buchanan and Bobby (1992), he recommends two negotiation clusters. Selling plans and ideas to others; creating a desirable vision of the future and negotiating with key players for resources or changes in procedures, or to resolve conflict. Due to the facts that the employees are the key players, then they should have been consulted through the trade union. According to Elton Mayo, he said that workers are motivated by such things is that individuals have a deep psychological need to believe that their organization cares about them, is open, concerned, and willing to listen. In organisations, which have cultures in which individuals make their own decisions a change agent who attempts to manage process by telling people what to do is likely to encounter resistance. In this type of environment, the change agent perhaps needs to have a more laid back style, paying attention to altering, important symbols such as reward systems, or persuading his

An Epic Man Who Became an Epic Hero Essay Example for Free

An Epic Man Who Became an Epic Hero Essay Odysseus, of Homers Odyssey, is an appropriate hero and ruler of Ithaca. He does not act irrationally but contemplates his actions and their implications. Odysseus is an appropriate hero because he embodies the values of bravery, intelligence, astuteness, and competency. Odysseus is an appropriate ruler for Ithaca by virtue of his hereditary right to kingship as well as his diplomatic skills, familiarity with his male subjects, discipline, and his impartiality and compassion. However, he is a character that does make a foolish decision. There is a rare instance when his pride supersedes his intellectual ability. Odysseus is an appropriate hero for he embodies the values of bravery, intelligence, astuteness, and competency. While he trying to return home from Ilium, numerous suitors attempt to seduce his wife, Penelope. However, when he returns Odysseus cleverly plans and carries out the demise of the evil and wasteful suitors with the help of Athena, goddess of wisdom: Come on [Athena] weave me a plan to punish them [the suitors]. Odysseus wisdom is admired by Athena, the goddess of that aptness. Athena is also impressed by his battle heroics and so she endeavors to provide him with succor: And you didnt know Pallas Athenaia the daughter of Zeus himself, your faithful stand-by and guardian in all your labours! With Athenas assistance Odysseus becomes a true hero. Odysseus is the epitome of honor and virtue for his Ithacan subjects. Odysseus kind and stalwart leadership is revealed by Eumaios, his faithful swineherd, and Philoitios, his loyal cowherd, who have both remained loyal to him for twenty years. Eumaios praises Odysseus as A rare fine master. Indeed I do not mourn so much for them as for him [Odysseus], though I long to see em again and my native land, but I do miss Odysseus since he went away. I dont like to speak his name, man, although he is absent, but I call him his honour, even when he is far away. Odysseus is a befitting king because it is his ancestral right, for he is familiar with his male subjects and understands their desires. Odysseus equity and mercy is displayed after his triumph over the suitors, whom he executed because of their lawless  behavior. However, Odysseus shows compassion by allowing Phemius, the minstrel suitor, and Medon, a herald suitor to live. Cheer up, my son has saved your life. So you shall know, and tell other men, that doing well is far better than doing ill. Odysseus proper sovereignty is expressed by his justice. Odysseus displays his shrewdness as he overcomes the challenges that beset his crew. When Odysseus and his men become trapped by Polyphemos on the island of the Cyclops, Odysseus cleverly tells Polyphemos that his name is Noman. Thus, when Polyphemos is stabbed in the eye by Odysseus and his men, he renounces assistance from his friends by stating that Noman is killing me, leading his companions to believe that no man has hurt him. However, once Odysseus and his men reach their ships and set sail, he performs his most foolish act. Odysseus taunts Polyphemos by declaring, if ever any one asks who put out you ugly eye, tell him your blinder was Odysseus, the conqueror if Troy, the son of Laertes, whose address is Ithaca! Once Polyphemos obtains this critical information on his blinders identity, he implores his father Poseidon, god of the sea, to grant that Odysseus the conqueror if Troy- the son of Laertes- whose address is Ithaca, may never reach his home! Because Odysseus pride would not allow him to let his ingenious action go unrecognized, he dooms himself and his crew. Odysseus wisdom and courage enable him to be a brave hero and a strong ruler, both traits of superiority in his society. Being mortal binds him to occasional mistakes that he compensates for by becoming wiser and stronger. His extraordinary abilities are heralded by the gods. Upon his return to Ithaca, Odysseus ingeniously kills the rude and wasteful suitors and reclaims his title of king. In reconciliation and honor, he finally makes a sacrifice to Poseidon. Odysseus is the epitome of a hero of his culture.

Use of Distributed Computing in Processing Big Data

Use of Distributed Computing in Processing Big Data Distributed Systems is an upcoming area in computer science and has the ability to have a large impact on the many aspects in[G1] the medical, scientific, financial and commercial sector. This document will provide an overview of distributed systems along with their current applications and application in big data. The most commonly used definition for a distributed system is, a system comprised of geographically dispersed computing components interacting on a hardware or software level [1].The rise in interest for distributed computing can be attributed to two major factors. The first factor is the creation and advancements in local and wide area networks which allow for large amounts of data to be transmitted over great distances in a short period of time [2]. The second factor is the new craze of the Internet of Things (IoT), where nearly every physical device manufacture having some sort of internet connectivity allowing for the possibility of tens of billions of devices that are able to interact. This large network of interconnected devices can be utilised to compute large amounts of data in a fraction of the time it would currently take to process. Characteristics of a Distributed System Heterogeneity Heterogeneity refers to the ability for the system to operate on a variety of different hardware and software components. This is achieved through the implementation of middleware in the software layer. The goal of the middleware is to abstract and interpret the programming procedural calls such that the distributed processing can be achieved on a variety of differing nodes [3]. Openness The openness of a distributed system is defined as the difficulty involved to extend or improve an existing system. This characteristic allows us to reuse a distributed system for multiple functions or to process varying sets of data. Concurrency Concurrency refers to the systems ability to handle the access and use of shared recourses. This is important because if there is no measure implemented it is possible for data to get corrupted or lost by two nodes making different changes to the same resource such that the system can carry this error through different processes causing an incorrect result. One way to counteract these errors is to implement a locking mechanism making a node unable to access a resource whilst it is being used by another node.[G2][G3] Scalability Scalability is one of the major characteristics that effectiveness of a distributed system, it refers to how easily the system can adapt to a changing size. This is due to the volatile nature of computers, such that a device is prone to leaving and joining the system at will. This volatility is caused by computers powering down, or unstable networks causing connectivity issues.[G4][G5] One factor that affects scalability is the degree at which the system is centralised. This is due to if a system relies on a centralised component or process (e.g. a central [G6]server), the more nodes that try to communicate or use this component, the more likely it is that there will be a bottleneck at this point in the system.[G7] Fault Tolerance Due to a distributed system having many computers comprised of different aged hardware, it is very likely for a part to fail in such a way that a node can no longer operate. Fault Tolerance is the ability for the system to handle such failures, this is achieved by using recovery and redundancy. Recovery is [G8]where a component will act in a predictable, controlled way if it relies on a component. Redundancy is where crucial systems and processes will have a backup that takes over if a system fails.[G9][G10] Transparency Transparency in a distributed system refers to the idea that the user perceives that they are interacting with a whole quantity rather than a collection of cooperating components. Transparency can be split into the following 8 sub-characteristics defined in Table 1. Table 1 Different forms of transparency in a distributed system [2]. Transparency Description Access Hide differences in data representation and how an object is accessed Location Hide where an object is located Relocation Hide that an object may be moved to another location while in use Migration Hide that an object may move to another location Replication Hide that an object is replicated Concurrency Hide that an object may be shared by several independent users Failure Hide the failure and recovery of an object The Internet The internet is the largest and most well-known decentralised distributed system ever created. It is currently comprised of millions of geographically distributed interconnected web servers that can communicate autonomously with each other and the billions of endpoint nodes [4]. The internet is constantly growing with more website and nodes added every day. One of the major factors contributing to the growth of nodes is the boost in IoT or smart devices. ATM Machines ATM machines are an example of a centralised distributed system that has been implemented globally. This is a centralised system because each ATM machine will [G11]only communicate with its bank central server. Centralisation is enforced as a measure to increase the security of the sensitive information stored on the banks databases[G12]. Each banks ATM network has the ability to communicate with another banks server [G13]such that a user can withdraw money from any ATM around the world. Botnets Botnets are an example of a malicious distributed system. They are can either be operated by a central server or based off a peer-[G14]to-peer network. A botnet is comprised of a collection of zombie machines which have been infected with malware allowing the bot master to control it and a command and control server whose role is to control the zombie computers allowing the zombie machines to execute any command that the botmaster desires. Data is any accumulation of facts and statistics to be analysed or referenced. Big data is most commonly defined as extremely large sets of data, both structured and unstructured, [G15]that can be analysed to reveal patterns and trends. This data is sufficiently complex or large enough that conventional data processing processes and applications are unable to deal with it [5]. Crowdsourcing is not a new idea in the software world, it is not an uncommon sight to see a developer pose a task to the masses and have someone else complete the task. This is mostly done free of charge. A similar concept is starting to be applied to big data, where researchers and institutes have started to crowdsource data for people to process[G16]. Currently, most data that has been crowdsourced is [G17]for scientific or medical research. A factor that contributes to the success of data processing on distributed systems is the relatively low cost of [G18]transferring data compared the cost incurred from doing the data processing internally [6].[G19] Play to Cure: Genes in Space Play to Cure: Genes in Space is a mobile gaming application developed by Cancer Research UK. Its main purpose is to allow the general public to process large amounts of data for the scientist at Cambridge University.[G20] The data is processed by the user controlling a spaceship to try and collect as much Element Alpha as possible. What the user is not aware that the placement of Element Alpha directly correlates to a singular piece of plotted data [7]. In the first month alone the application has managed to analyse 1.5 million data sample. To process a similar number of samples the research team achieve a similar amount of samples processed, it would take the research team 125,000 man hours [7]. Whilst it is a rudimentary implementation of a distributed system, Play to Cure: Genes in Space is a successful implementation and can show how important large distributed systems can processing big data. [emailprotected] [emailprotected] is currently the largest distributed computing program and was created by the SETI (Search for Extraterrestrial Intelligence) Institute and hosted out at UC Berkeley. It currently has approximately 3 million active users donating their computers[G21][G22] spare processing power to process data obtained from SETIs radio telescopes [8]. Since [emailprotected] is a voluntary program, each node needs to be able to process data in a way that the user is not negatively affected and choose to leave the program. This is achieved through the application processing data when it is detected that a machines CPU is [G23]idling [9]. As of the 10 March 2017, the [G24][emailprotected] program has come close to processing 18 years worth of data from the Arecibo Observatory radio telescope [10]. This achievement displays how easily large amounts of data can be processed by large distributed systems. There are endless possibilities when it comes to the potential applications[G25] for distributed systems. Processing big data is a lucrative market, this might cause a lot of large multinational organisation to try and utilise their own hardware to implement their own personal distributed system to process the terabytes of data that they can extrapolate from their Enterprise resource planning (ERP) software and from data obtained from the media and other sources. Stock trading is a cut throat industry, and the ability to predict market trends faster than a competitor can allow a particular firm to make millions of dollars. It is plausible for large firms to implement their own distributed system to analyse previous market trends and current global and local affairs to predict the upcoming state of the market. In the future, distributed systems will allow for big data to be processed potentially at a near real-time timeframe. This document has outlined how distributed systems can assist in the faster and more effective processing of big data. References [1]H. Karatza and G.
