Evaluating social skills in long term cochlear implant recipients

A longitudinal study observing cochlear implant recipients' social skills using ratings from their parents and the students themselves over time. The study looked at how adolescents using cochlear implants rate their own social skills compared to an age matched normative group of hearing students, and compared these ratings with social skills ratings obtained from their parents. The study also compared social ratings in adolescence to previous ratings of the same children obtained in elementary school.

Ventilation rates in schools and pupil’s performance using computerized assessment tests

Research shows that poor indoor air quality (IAQ) in school buildings can cause a reduction in the students’ performance assessed by short-term computer-based tests; whereas good air quality in classrooms can enhance children's concentration and also teachers’ productivity. Investigation of air quality in classrooms helps us to characterise pollutant levels and implement corrective measures. Outdoor pollution, ventilation equipment, furnishings, and human activities affect IAQ. In school classrooms, the occupancy density is high (1.8–2.4 m2/person) compared to offices (10 m2/person). Ventilation systems expend energy and there is a trend to save energy by reducing ventilation rates. We need to establish the minimum acceptable level of fresh air required for the health of the occupants. This paper describes a project, which will aim to investigate the effect of IAQ and ventilation rates on pupils’ performance and health using psychological tests. The aim is to recommend suitable ventilation rates for classrooms and examine the suitability of the air quality guidelines for classrooms. The air quality, ventilation rates and pupils’ performance in classrooms will be evaluated in parallel measurements. In addition, Visual Analogue Scales will be used to assess subjective perception of the classroom environment and SBS symptoms. Pupil performance will be measured with Computerised Assessment Tests (CAT), and Pen and Paper Performance Tasks while physical parameters of the classroom environment will be recorded using an advanced data logging system. A total number of 20 primary schools in the Reading area are expected to participate in the present investigation, and the pupils participating in this study will be within the age group of 9–11 years. On completion of the project, based on the overall data recommendations for suitable ventilation rates for schools will be formulated.

Exploring the role of design quality in the Building Schools for the Future programme

The Building Schools for the Future (BSF) programme represents the biggest single UK government investment in school buildings for more than 50 years. A key goal for BSF is to ensure that pupils learn in 21st-century facilities that are designed or redesigned to allow for educational transformation. This represents a major challenge to those involved in the design of schools. The paper explores the conceptualizations of design quality within the BSF programme. It draws on content analysis of influential reports on design published between 2000 and 2007 and interviews with key actors in the provision of schools. The means by which design quality has become defined and given importance within the programme through official documents is described and compared with the multiple understandings of design quality among key stakeholders. The findings portray the many challenges that practitioners face when operationalizing design quality in practice. The paper concludes with reflections on the inconsistencies between how design quality has been appropriated in the BSF programme and how it is interpreted and adopted in practice.

The contributions of domain-general and numerical factors to third-grade arithmetic skills and mathematical learning disability

Explanations of the marked individual differences in elementary school mathematical achievement and mathematical learning disability (MLD or dyscalculia) have involved domain-general factors (working memory, reasoning, processing speed and oral language) and numerical factors that include single-digit processing efficiency and multi-digit skills such as number system knowledge and estimation. This study of third graders (N = 258) finds both domain-general and numerical factors contribute independently to explaining variation in three significant arithmetic skills: basic calculation fluency, written multi-digit computation, and arithmetic word problems. Estimation accuracy and number system knowledge show the strongest associations with every skill and their contributions are both independent of each other and other factors. Different domain-general factors independently account for variation in each skill. Numeral comparison, a single digit processing skill, uniquely accounts for variation in basic calculation. Subsamples of children with MLD (at or below 10th percentile, n = 29) are compared with low achievement (LA, 11th to 25th percentiles, n = 42) and typical achievement (above 25th percentile, n = 187). Examination of these and subsets with persistent difficulties supports a multiple deficits view of number difficulties: most children with number difficulties exhibit deficits in both domain-general and numerical factors. The only factor deficit common to all persistent MLD children is in multi-digit skills. These findings indicate that many factors matter but multi-digit skills matter most in third grade mathematical achievement.

Methods to assess the effectiveness of naturally ventilated classrooms in Gauteng, South Africa

There is a tendency to reduce ventilation rates and natural or hybrid ventilation systems to ensure the conservation of energy in school buildings. However, high indoor pollutant concentration, due to natural or hybrid ventilation systems may have a significant adverse impact on the health and academic performance of pupils and students. Reviewed evidence shows that this can be detrimental to health and wellbeing in schools because of the learner density within a small area, eventually indicating that CO2 concentrations can rise to very high levels (about 4000 ppm) in classrooms during occupancy periods. In South Africa’s naturally ventilated classrooms, it is not clear whether the environmental conditions are conducive for learning. In addition, natural ventilation will be minimized given the fact that in cold, wet or windy weather, doors and windows will commonly remain closed. Evidence from literature based studies indicates that the significance of ventilation techniques is not understood satisfactorily and additional information concerning naturally ventilated schools has to be provided for better design and policy formulation. To develop a thorough understanding of the environments in classrooms, many other parameters have to be considered as well, such as outdoor air quality, CO2 concentrations, temperature and relative humidity and safety issues that may be important drawbacks for naturally ventilated schools. The aim of this paper is to develop a conceptual understanding of methods that can be implemented to assess the effectiveness of naturally ventilated classrooms in Gauteng, South Africa. A theoretical concept with an embedded practical methodology have been proposed for the research programme to investigate the relationship between ventilation rates and learning in schools in Gauteng , a province in South Africa. It is important that existing and future school buildings must include adequate outdoor ventilation, control of moisture, and avoidance of indoor exposures to microbiologic and chemical substances considered likely to have adverse effects in South Africa. Adequate ventilation in classrooms is necessary to reduce and/or eradicate the transmission of indoor pollutants.

Vasectomy within the public health services in Campinas, Sao Paulo, Brazil

Objective: To describe some of the characteristics of men who underwent a vasectomy in the public health network of Campinas, Sao Paulo, Brazil. Methods: A descriptive study including 202 men randomly selected from a list of all the men vasectomized between 1998 and 2004 in the public health network. Results: Most of the men were 30 years of age or older when vasectomized, had completed elementary school and had two or more children of both sexes. Most of the men came from the lowest income segment of the population: 47.6% in 1998-1999 and 61.3% in 2003-2004. Although the men knew various contraceptive methods, 51.2% reported that their partners were using combined oral contraceptives at the time of surgery. Most men initially sought information on vasectomy at health-care clinics where care was provided by a multidisciplinary team; most received counselling, however, 47.9% of the men waited more than 4 months for the vasectomy. Conclusions: The profile of the vasectomized men in this study appears to indicate that the low-income population from Campinas, Sao Paulo, Brazil has access to vasectomy; however, the waiting time for vasectomy reveals that difficulties exist in obtaining this contraceptive method in the public health service.

Electricity Supply Solutions for an Educational Center in Tanzania

The aim of this study was to investigate electricity supply solutions for an educationalcenter that is being built in Chonyonyo Tanzania. Off-grid power generation solutions andfurther optimization possibilities were studied for the case.The study was done for Engineers Without Borders in Sweden. Who are working withMavuno Project on the educational center. The school is set to start operating in year 2015with 40 girl students in the beginning. The educational center will help to improve genderequality by offering high quality education in a safe environment for girls in rural area.It is important for the system to be economically and environmentally sustainable. Thearea has great potential for photovoltaic power generation. Thus PV was considered as theprimary power generation and a diesel generator as a reliable backup. The system sizeoptimization was done with HOMER. For the simulations HOMER required componentdata, weather data and load data. Common components were chose with standardproperties, the loads were based on load estimations from year 2011 and the weather datawas acquired from NASA database. The system size optimization result for this base casewas a system with 26 kW PW; 5.5 kW diesel generator, 15 kW converter and 112 T-105batteries. The initial cost of the system was 55 875 €, the total net present cost 92 121 €and the levelized cost of electricity 0.264 €/kWh.In addition three optimization possibilities were studied. First it was studied how thesystem should be designed and how it would affect the system size to have night loads(security lights) use DC and could the system then be extended in blocks. As a result it wasfound out that the system size could be decreased as the inverter losses would be avoided.Also the system extension in blocks was found to be possible. The second study was aboutinverter stacking where multiple inverters can work as one unit. This type of connectionallows only the required number of inverters to run while shutting down the excess ones.This would allow the converter-unit to run with higher efficiency and lower powerconsumption could be achieved. In future with higher loads the system could be easilyextendable by connecting more inverters either in parallel or series depending on what isneeded. Multiple inverters would also offer higher reliability than using one centralizedinverter. The third study examined how the choice of location for a centralized powergeneration affects the cable sizing for the system. As a result it was found that centralizedpower generation should be located close to high loads in order to avoid long runs of thickcables. Future loads should also be considered when choosing the location. For theeducational center the potential locations for centralized power generation were found outto be close to the school buildings and close to the dormitories.

A Catalyst for Culture: Early Child Development and Education in Japan

A popular Western perception of Japan is that it is an eminently homogeneous and conformist society. However, both conformity and homogeneity, recognized even by the Japanese themselves, coexist with the concept of individuality, which is valued in a manner unique to its culture. In order to come to a deeper understanding of that dynamic, it is important to comprehend the specifics of child rearing and education within Japanese society. Based in part on the author's observational fieldwork conducted while in Japan in 1994, the thesis explicates the manner in which various core relationships exhibit the socialization of an individual that occurs within the home during a child's first few years. Furthermore, the text incorporates research in both primary and secondary historical materials. The author displays the manner in which educational issues such as the development of the Japanese education system and the dynamics of the elementary years serve to demonstrate the importance of functioning within a group. This is further clarified through an examination of elementary school texts, which also reveal underlying moral messages of profound importance in Japanese society. The seemingly contradictory issues of becoming an individual yet performing as a member of a group are pulled together by the idea that culture provides the guidance by which an individual becomes an active member of society. In Japan, individuality and group conformity are not mutually exclusive. Within the context of Japanese society, individuality is inextricably linked to group orientation.

A representação de música brasileira nos livros didáticos de música

O presente trabalho de pesquisa teve como objetivo analisar de que forma a música brasileira é representada nos livros didáticos de música direcionados para a escola do Ensino Básico e produzidos no Brasil nas décadas de 60 e 70. A escolha desse período é justificada por ser nessas décadas que a música brasileira é apresentada como conteúdo nos livros didáticos de forma mais acentuada do que em outros períodos. Tendo como referencial teórico-metodológico o conceito de representação de R. Chartier, o estudo procurou abarcar as concepções explícitas e implícitas, relativo a idéias, valores e intenções que perpassam nos textos e imagens, permitindo compreender o porquê de certas escolhas referentes a determinados conteúdos, em detrimento de outros, da forma como são abordados nos livros didáticos, bem como identificar os cânones eleitos para representar estilos, gêneros musicais, compositores, obras e épocas da música brasileira.

Diagnóstico das micro e pequenas empresas da cadeia produtiva moveleira da serra gaúcha : importância para o desenvolvimento setorial

The increasing of afluence demands the companies to be competitive and have a deep knowledge about the area wich they are participating. Through the search of management and produtive information, and the analisys of internal and external information, the company could identify strong and weak points , threats and oportunities, alowing the obtaince of competitive advantages. This research shows the result of a close search study about the usage of strategic planning and management technics, setting in evidence the necessity of micro and small furniture companies and furniture supply chain, represented in this case by sub-contract companies. Still looking to accentuate the importance that this study will represent to the setorial development, specially to the furniture companies wich have a big importance due to the report of small utilization of management technics in the sub-contract companies. Through analisys, it was possible to find out some common caracteristics in all 171 conmpanies evaluated, wich are showing likely 'sinalization', such as: - lower level os scholarship (96,5% elementary school, 3% until high school, 0,5% university/college graduration); - external market from Brazilian MPE¿s (5% export products to Mercosul and just 1% export products to Latin America, absenting exportations to other markets); - carefree with modern technics of management, certificates ISO 9000, 14000, MRP, CQT, among others; - carefree with strategic planning; - lower utilization of operacionl procedures, rules and function description; - ignoring the participating of market; - lower utilization of human resources index as a management form; - Small utilization of costs tabs (31%), with a small informatization level (8%) and apllying with non-management form; - low utilization of quality statistics (4%), re-working index (9%), among others. In syntesis, the basis expose that the great marjority of companies don¿t have knowledge about planning and the modern technics of management.

Three essays on education from the perspective of the economics of public setor

This work consists of three essays organized into chapters that seek to answer questions at first sight unrelated, but with one common denominator, which is the scarcity of public resources devoted to education, overall, especially in lower education. . The first chapter deals with the scarcity of resources devoted to education in a context of population aging. Two hypotheses were tested for Brazilian municipalities on the relationship between the aging of the population and educational expenditure. The first, already proven in the literature, is that there is an intergenerational conflict for resources and the increase of the share of elderly in the population reduces the educational expenditure. The second, proposed here for the first time, is that there should be reduction of competition for resources if there is a relationship of co-residence between young and old. The results indicated that an increase in the share of elderly reduces the educational expenditure per youth. But the results also illustrate that an increase in the share of elderly co-residing with youth (family arrangement more common in Latin American countries) raises the educational expenditure, which reflects a reduction of competition for resources between generations. The second chapter assesses the allocative efficiency of investments in Higher Education. Using the difference between first-year and last-year students’ scores from Enade aggregated by HEI as a product in the Stochastic Production Function, is possible to contribute with a new element in the literature aimed at estimating the production function of education. The results show that characteristics of institutions are the variables that best explain the performance of students, and that public institutions are more inefficient than the private ones. Finally, the third chapter presents evidence that the allocation of public resources in early childhood education is important for a better future school performance. In this chapter was calculated the effects of early childhood education on literacy scores of children attending the 2nd grade of elementary school. The results using OLS and propensity score matching show that students who started school at the ages to 5, 4, and 3 years had literacy scores between 12.22 and 19.54 points higher than the scores of those who began school at the ages 6 years or late. The results also suggest that the returns in terms of literacy scores diminish in relation to the number of years of early childhood education.
