    Full Text Available Introduction: This study deals with young people receiving special needs education in schools and their transition to lasting employment in private or public sector. Through a qualitative approach, the article aims at “identifying significant factors which can, contribute to successful transitions from school to lasting employment affiliation for pupils in vocational training programs”Theoretical approach: The theoretical approach of this article is descriptions and interpretation of the Norwegian educational legislation and the theory of «empowerment». These theoretical perspectives will be included in the empirical discussion. Method: The methodological approach is qualitative. Through four semi-structured interviews of young informants who have completed upper secondary school in a vocational education program, and have had a minimum of one-year training in an enterprise. Thematic analysis of the data is conducted with the application of NVivo 11, a computer program that is suitable for qualitative data-analysis and mixed research methods.Results and discussion: Through thematic analysis of the data, we found three significant factors contributing to successful transitions from school to lasting employment:      a Application and development of the pupil’s competence - mastery and meaning      b The significance of relations, communication and well-functioning socio-ecological          networks      c The importance of pupil participation and involvement in decision making

  6. Some conditions for significant contribution from photovoltaics to sustainable development

    International Nuclear Information System (INIS)

    Coiante, D.


    In medium-long term perspective, the anthropogenic atmospheric pollution, due to fossil fuel burning, could be contained by massively using of renewable energy. Significant improvements are expected to arise from diffusion into use of large scale PV power systems. Considering the situation in Italy as a typical study case, a limit can be individuated, which makes that PV contribution to annual electric energy balance can reach a maximum of about 7%. Such a figure corresponds to about 2% in terms of contribution to total energy balance. Thus, the intermittent energy sources are destined, in Italy, to be confined to a role, just significant (7%) in the electric energy sector, but quite marginal (2%) with reference to expected environmental massive benefits. Apart from numerical results, this disappointing concept can be applied in general to all OCSE countries, wich globally produce the largest amount of world pollutant energy. Consequently, if photovoltaics wants to acquire a real environmental consistence, the limit of PV system diffusion has to be overcome. This can be attained by implementing the present grid-tied reference model for PV system diffusion by including an hydrogen production and storage system

  9. Do Israeli health promoting schools contribute to students' healthy eating and physical activity habits? (United States)

    Hayek, Samah; Tessler, Riki; Bord, Shiran; Endevelt, Ronit; Satran, Carmit; Livne, Irit; Khatib, Mohammed; Harel-Fisch, Yosi; Baron-Epel, Orna


    The Israeli Health Promoting School Network (HPSN) is actively committed to enhancing a healthy lifestyle for the entire school population. This study aimed to explore the contribution of school participation in the HPSN and students' individual characteristics to healthy eating and physical activity habits among Israeli school children aged 10-12 years. A cross-sectional survey was conducted among 4166 students in grades 4-6 from 28 schools. The schools were selected from a sample of HPSN affiliated and non-HPSN schools. The contribution of individual characteristics (grade, gender and subjective self-reported health education activities at school) and school characteristics (school type, population group, deprivation score) to healthy eating and physical activity habits was analyzed using multi-level hierarchical models. Multi-level analysis indicated that student's individual characteristic was significantly associated with healthy eating and physical activity habits. The subjective self-reported health education received at school was statistically significant factor associated with students' health behaviors. The school's affiliation with the HPSN was not associated with higher healthy eating and physical activity scores after adjusting for individual factors. These findings suggest that Israeli HPSN schools do not contribute to children's health behaviors more than other schools. Therefore, health promoting activities in HPSN schools need to be improved to justify their recognition as members of the HPS network and to fulfill their mission. © The Author 2017.

  11. Colour contribution to children's wayfinding in school environments (United States)

    Helvacıoǧlu, Elif; Olguntürk, Nilgün


    The purpose of this study was to explore the contribution of colour to children's wayfinding ability in school environments and to examine the differences between colours in terms of their remembrance and usability in route learning process. The experiment was conducted with three different sample groups for each of three experiment sets differentiated by their colour arrangement. The participants totalled 100 primary school children aged seven and eight years old. The study was conducted in four phases. In the first phase, the participants were tested for familiarity with the experiment site and also for colour vision deficiencies by using Ishihara's tests for colour-blindness. In the second phase, they were escorted on the experiment route by the tester one by one, from one starting point to one end point and were asked to lead the tester to the end point by the same route. In the third phase, they were asked to describe verbally the route. In the final phase, they were asked to remember the specific colours at their correct locations. It was found that colour has a significant effect on children's wayfinding performances in school environments. However, there were no differences between different colours in terms of their remembrances in route finding tasks. In addition, the correct identifications of specific colours and landmarks were dependent on their specific locations. Contrary to the literature, gender differences were not found to be significant in the accuracy of route learning performances.

    Full Text Available International students’ contribution to Higher Education Institutions (HEIs tends to be considered from different aspects. There is an inadequate substantiation base that would allow academics, researchers and other stakeholders understand the importance of overseas students in the UK Business Schools. This paper investigates the contribution of international students to Business School in the UK HEIs. The research was exploratory and part of a bigger project on how and why Business Schools in the UK use Relationship Marketing to retain international students. It employed semi-structured interviews with 18 members of staff from four Business Schools in the North of England. Findings indicate that international students’ definition tends to differ amongst staff members within the Business Schools. Business Schools’ management perceive overseas students as an integral part of their institutions, especially as their overall contributions cannot be over-emphasised. The sample size and use of semi-structured interviews, as a single data gathering strategy, does not allow broad generalisation of findings. The obtained evidence can still be used as a platform for further research in this area.

  16. Transformational Approach To School Leadership: Contribution To Continued Improvement Of Education

    Directory of Open Access Journals (Sweden)

    Anca Nedelcu


    Full Text Available Over the last decades, an impressive number of conceptual models in the field of educational leadership have emerged; contingency or trait theories, situational, instructional, shared or distributed school leadership approaches, all tried to demonstrate their specific impact on school development and students achievement. The present paper is focused on exploring one of the foremost models, subject of systematic inquiry and controversial debates developed in relation with school or in nonschool organizations: transformational school leadership. The approach is considered a relevant support for school change process. Its contribution is analyzed in comparison with the benefits of other competing models, the aim of the paper being not to establish hierarchies but to gather significant solutions for better schooling. As a reconciliation solution, the integrative leadership model is also advocated.

  17. Contribution of school to building up the partnership with parents

    Polovina Nada


    Full Text Available This paper studies the way in which headmasters and class masters perceive and estimate the factors, obstacles and incentives to building up a partnership between school and parents. The sample consists of 60 headmasters and 305 class masters from 60 schools (37 urban and 23 rural in Serbia. Headmasters and teachers filled in separate, but parallel questionnaires (modified only in the segment of different roles that were created for the purposes of research. Questionnaire items inquire about the factors contributing to the inclusion of parents, the obstacles in developing the cooperation between parents and school and the peculiarities of school environment that can contribute to the development of that cooperation, as well as about the peculiarities of the communication with parents. Research findings indicate that headmasters and teachers assess the importance of different components in the field of cooperation with parents in a similar, but not identical way. Most similarities are found in the perception of obstacles for establishing cooperation (the problems of coordinating time periods for meetings, previous bad experiences of parents regarding cooperation. The majority of differences lie in perceiving the importance of cooperation factors (headmasters emphasise the "parent factor", while teachers do so both for the "parent factor" and "child factor", as well as in perceiving the necessary incentives for the improvement of cooperation between school and parents (headmasters emphasise the spatial-temporal organization components, and teachers do so for spatial components and personal initiatives. In the assessments of both the headmasters and teachers we obtained differences marked by gender, the longitude of years of service, size of the settlement where the school is located (town-village. The general conclusion indicates that the topic of cooperation between school and parents is highly and in many ways context sensitive, and that the

  2. Pharmaceuticals occurrence in a WWTP with significant industrial contribution and its input into the river system

    International Nuclear Information System (INIS)

    Collado, N.; Rodriguez-Mozaz, S.; Gros, M.; Rubirola, A.; Barceló, D.; Comas, J.; Rodriguez-Roda, I.; Buttiglieri, G.


    Occurrence and removal of 81 representative Pharmaceutical Active Compounds (PhACs) were assessed in a municipal WWTP located in a highly industrialized area, with partial water reuse after UV tertiary treatment and discharge to a Mediterranean river. Water monitoring was performed in an integrated way at different points in the WWTP and river along three seasons. Consistent differences between therapeutic classes were observed in terms of influent concentration, removal efficiencies and seasonal variation. Conventional (primary and secondary) treatment was unable to completely remove numerous compounds and UV-based tertiary treatment played a complementary role for some of them. Industrial activity influence was highlighted in terms of PhACs presence and seasonal distribution. Even if global WWTP effluent impact on the studied river appeared to be minor, PhACs resulted widespread pollutants in river waters. Contamination can be particularly critical in summer in water scarcity areas, when water flow decreases considerably. -- Highlights: • Seasonal variation revealed a higher spring-summer removal compared to winter time. • Biological process was unable to provide a complete removal for most compounds. • UV-based tertiary treatment did play a complementary removal role for specific PhACs. • Diffuse river contamination and local WWTP contribution to it were observed. • River attenuation capacity is an important factor for removing most of the compounds. -- PhACs integrated WWTP-river data evaluation of coupled biological process and UV tertiary treatment in a WWTP with significant industrial contribution and in the receiving river waters

  3. The Little Engines That Could? Globular Clusters Contribute Significantly to Reionization-era Star Formation (United States)

    Boylan-Kolchin, Michael


    Metal-poor globular clusters (GCs) are both numerous and ancient, which indicates that they may be important contributors to ionizing radiation in the reionization era. Starting from the observed number density and stellar mass function of old GCs at z = 0, I compute the contribution of GCs to ultraviolet luminosity functions (UVLFs) in the high-redshift Universe (10 ≳ z ≳ 4). Even under absolutely minimal assumptions - no disruption of GCs and no reduction in GC stellar mass from early times to the present - GC star formation contributes non-negligibly to the UVLF at luminosities that are accessible to the Hubble Space Telescope (HST; M1500 ≈ -17). If the stellar masses of GCs were significantly higher in the past, as is predicted by most models explaining GC chemical anomalies, then GCs dominate the UV emission from many galaxies in existing deep-field observations. On the other hand, it is difficult to reconcile observed UVLFs with models requiring stellar masses at birth that exceed present-day stellar masses by more than a factor of 5. The James Webb Space Telescope (JWST) will be able to directly detect individual GCs at z ˜ 6 in essentially all bright galaxies, and many galaxies below the knee of the UVLF, for most of the scenarios considered here. The properties of a subset of high-redshift sources with -19 ≲ M_{1500} ≲ -14 in HST lensing fields indicate that they may actually be GCs in formation.

  5. The contribution of school-level factors to contraceptive use among adolescents in New York city public high schools (United States)

    Kaplan, Deborah L.

    Every year approximately 17,000 adolescents ages 15-19 become pregnant in New York City. Most of these pregnancies are unintended and only a small percent of adolescents use effective contraception, with wide disparities by race/ethnicity and poverty level. While many studies have identified factors associated with contraceptive use, most research has focused on individual level factors, with little attention to the contribution of the school environment to sexual risk behavior and contraceptive use. This study investigates the effect of school-level factors on contraceptive use among adolescents in NYC public high schools before and after controlling for individual-level factors, and whether this effect varies with race/ethnicity. Using a cross-sectional design, the NYC Youth Risk Behavior Survey (YRBS) individual-level datasets for 2007, 2009 and 2011 were linked to a school-level dataset. Variables were selected based on empirical findings on factors associated with sexual behaviors, including contraceptive use, by adolescents. The analytic sample included all YRBS respondents aged 14 or older who reported having sexual intercourse in the past three months and had complete responses to the YRBS questions on contraceptive use at last sex (N=8,054). The chi square test of significance was used to evaluate significant associations between independent variables and contraceptive use in bivariate analyses; variables with a p value < 0.1 were included in the multivariable analyses. Binary and multinomial logistic regression analyses were conducted to estimate the strength of the associations of school-level factors with contraceptive use among sexually active adolescents. Findings included that use of any contraception and/or hormonal contraception at last sexual intercourse was associated with attending schools with a higher six-year graduation rate, higher percent of students strongly agreeing they were safe in their classrooms, higher percent of teachers at the

  6. Human Sterol Regulatory Element-Binding Protein 1a Contributes Significantly to Hepatic Lipogenic Gene Expression

    Directory of Open Access Journals (Sweden)

    Andreas Bitter


    Full Text Available Background/Aims: Sterol regulatory element-binding protein (SREBP 1, the master regulator of lipogenesis, was shown to be associated with non-alcoholic fatty liver disease, which is attributed to its major isoform SREBP1c. Based on studies in mice, the minor isoform SREBP1a is regarded as negligible for hepatic lipogenesis. This study aims to elucidate the expression and functional role of SREBP1a in human liver. Methods: mRNA expression of both isoforms was quantified in cohorts of human livers and primary human hepatocytes. Hepatocytes were treated with PF-429242 to inhibit the proteolytic activation of SREBP precursor protein. SREBP1a-specifc and pan-SREBP1 knock-down were performed by transfection of respective siRNAs. Lipogenic SREBP-target gene expression was analyzed by real-time RT-PCR. Results: In human liver, SREBP1a accounts for up to half of the total SREBP1 pool. Treatment with PF-429242 indicated SREBP-dependent auto-regulation of SREBP1a, which however was much weaker than of SREBP1c. SREBP1a-specifc knock-down also reduced significantly the expression of SREBP1c and of SREBP-target genes. Regarding most SREBP-target genes, simultaneous knock-down of both isoforms resulted in effects of only similar extent as SREBP1a-specific knock-down. Conclusion: We here showed that SREBP1a is significantly contributing to the human hepatic SREBP1 pool and has a share in human hepatic lipogenic gene expression.

  7. Physical activity energy expenditure in Dutch adolescents: contribution of active transport to school, physical education, and leisure time activities. (United States)

    Slingerland, Menno; Borghouts, Lars B; Hesselink, Matthijs K C


    Detailed knowledge about physical activity energy expenditure (PAEE) can guide the development of school interventions aimed at reducing overweight in adolescents. However, relevant components of PAEE have never been objectively quantified in this population. This study investigated the contribution of active transport to and from school, physical education (PE), and leisure time activities to total PAEE during a regular school week in adolescents. Seventy-three adolescents (mean age: 15.7 years) wore an individually calibrated combined heart rate-acceleration monitor and kept an activity diary during a regular school week. Branched equation modeling was used to calculate PAEE of the specific activity categories, and their relative contribution to total PAEE was determined. Active transport and PE contributed 30.0% and 17.4%, respectively, to school-related PAEE. Active transport to and from school contributed 15% to total PAEE. Youth with a high physical activity level (PAL) spent 4 hours less in sedentary behavior than subjects with a medium or low PAL (F = 77.415 (2.70), p activities (F = 10.583 (2.70), p Active transport and PE contribute significantly to PAEE during school hours in adolescents. To achieve an increase in total PAEE in the least active group of adolescents, promising strategies might be to reduce inactive behavior, increase participation in leisure time sports, and possibly to replace inactive for active jobs. © 2012, American School Health Association.

  8. Interallelic class switch recombination contributes significantly to class switching in mouse B cells. (United States)

    Reynaud, Stéphane; Delpy, Laurent; Fleury, Laurence; Dougier, Hei-Lanne; Sirac, Christophe; Cogné, Michel


    Except for the expression of IgM and IgD, DNA recombination is constantly needed for the expression of other Ig classes and subclasses. The predominant path of class switch recombination (CSR) is intrachromosomal, and the looping-out and deletion model has been abundantly documented. However, switch regions also occasionally constitute convenient substrates for interchromosomal recombination, since it is noticeably the case in a number of chromosomal translocations causing oncogene deregulation in the course of lymphoma and myeloma. Although asymmetric accessibility of Ig alleles should theoretically limit its occurrence, interallelic CSR was shown to occur at low levels during IgA switching in rabbit, where the definition of allotypes within both V and C regions helped identify interchromosomally derived Ig. Thus, we wished to evaluate precisely interallelic CSR frequency in mouse B cells, by using a system in which only one allele (of b allotype) could express a functional VDJ region, whereas only interallelic CSR could restore expression of an excluded (a allotype) allele. In our study, we show that interchromosomal recombination of V(H) and Cgamma or Calpha occurs in vivo in B cells at a frequency that makes a significant contribution to physiological class switching: trans-association of V(H) and C(H) genes accounted for 7% of all alpha mRNA, and this frequency was about twice higher for the gamma3 transcripts, despite the much shorter distance between the J(H) region and the Cgamma3 gene, thus confirming that this phenomenon corresponded to site-specific switching and not to random recombination between long homologous loci.

  10. Can Health Promoting Schools contribute to the better health and wellbeing of young people? The Hong Kong experience. (United States)

    Lee, Albert; Cheng, Frances F K; Fung, Yanas; St Leger, Lawrence


    The Health Promoting School (HPS) is a WHO sponsored framework, compiled to enable education and health sectors to be more effective in school based initiatives. This study attempted to test the hypothesis that students from schools that had comprehensively embraced the HPS concept as indicated by the Healthy School Award, were better, in terms of health risk behaviour, self reported health status, and academic results, than students from schools that did not reach the standard of the award. The results presented came from nine schools (four primary and five secondary) applying for accreditation of the Healthy Schools Award after adopting the HPS framework for two years. Regular consultancy support and training were available to all schools. Students had completed before and after surveys to assess their health behaviours, self reported health status, and academic standing before the two year intervention, and at its end. Data from the before and after surveys of the students attending schools that reached certain level of HPS standard as indicated by the award, were compared with students whose schools did not receive the award, and the results showed differences. Some differences were found to be more significant among the primary school students than secondary schools students. This illustrated early intervention for lifestyle changes to be more effective. Students' satisfaction with life also improved if their schools adopted the concept of HPS comprehensively. The results suggest that comprehensive implementation of HPS would contribute to differences in certain behaviours and self reported health and academic status.

  11. [The nurse's thought for a significant social contribution by the production and use of scientific knowledge]. (United States)

    Pépin, Jacinthe


    The social contribution of nurses to the health of the population is mainly defined by the knowledge supporting their actions. Conceptualization in nursing guides the production and utilisation of scientific knowledge within the discipline. The purpose of this paper is to present the recent thoughts on nursing theory and to provide some strategies to integrate them within the activities of knowledge mobilization, in practice, research, and education. When nurses are engaged in mobilizing theoretical and empirical knowledge in answering nursing practice questions and in discussing social health issues, they participate in persons, families, and communities health improvement, while affirming their disciplinary and social identity. Called to be change agents in health care systems, with other professional team members, it is important that nurses be prepared to mobilize knowledge and to engage in critical reasoning, and ethical conduct. Their social contribution will be as strong as the value they assign to nursing knowledge and their participation in producing it.


    Sigler-Harcavi, Alona; Cohen Ashkenazi, Limor


    Working with medical and paramedical teams has taught us that the medical staff does not fully utilize the potential of judicial decisions and precedents as a source for learning, drawing conclusions and motivating progress. Judicial ruling is an essential part of the toolbox used by medical administrators in general, and healthcare risk managers in particular. Knowing the relevant legal rulings, before you embark on any given path, is the equivalent of looking before you leap. This is not necessarily an issue of "holy scripture", but should mainly be considered as a source for expanding your perspective. Knowledge of the relevant rulings has many advantages that stem from the unique characteristics of the legal system. While the medical world has a clear and unequivocal advantage regarding knowledge and experience with respect to medicine, the legal world has various other advantages: a different and wider perspective with respect to economic and/or political considerations; universal fundamental principles, such as autonomy, equality, distributive justice, human dignity, the state's obligations to its citizens; complex systems of checks and balances, such as: desirable vs. available, the benefit of few vs. the good of the many, etc. These tools, typical of the legal world, are especially relevant to medicolegal issues, usually associated with medical administration, such as: the obligation of consultation, obligation of follow-up, treatment continuity, priorities, resource distribution, patient rights, etc. The contribution of the legal world to these issues is both unique and essential. Those who question the ability of judges to understand the medical world and to materially contribute to medical thinking and practice, claiming that they lack medical training and experience, should recognize the diverse contribution of the legal world to the medical world.

  16. Geological subsurface will contribute significantly to the implementation of the energy policy towards renewables in Germany (United States)

    Martens, Sonja; Kühn, Michael


    The demands to exploit the geological subsurface are increasing. In addition to the traditional production of raw materials such as natural gas and petroleum, or potable groundwater extraction the underground will most likely also be used to implement the climate and energy policy objectives in the context of the energy transition to renewables. These include the storage of energy from renewable sources (e.g. hydrogen and methane), the use of geothermal energy and possibly the long-term storage of carbon dioxide to reduce the release of greenhouse gases into the atmosphere. The presentation addresses the question which realistic contribution can be expected from the geo-resource subsurface for the energy revolution, the detachment of fossil and nuclear fuels as well as the reduction of CO2 emissions. The study of Henning and Palzer [1] that models the energy balance of the electricity and heat sector including all renewable energy converters, storage components and loads for a future German energy system shows that provision with 100% renewables is economically feasible by 2050. Based on their work, our estimates underline that already in 2015 more than 100% of the required methane storage capacities therein are available and more than 100% of the heat pump demands might be covered by shallow and deep geothermal energy production in the future. In addition we show that a newly developed energy storage system [2-3] could be applied to store 20-60% of the surplus energy from renewables expected for 2050 with integrated gas storage of methane and CO2.

  17. Significant Contributions of the Albrecht's A Term to Nonresonant Raman Scattering Processes. (United States)

    Gong, Zu-Yong; Tian, Guangjun; Duan, Sai; Luo, Yi


    The Raman intensity can be well described by the famous Albrecht's Raman theory that consists of A and B terms. It is well-known that the contribution from Albrecht's A term can be neglected without any loss of accuracy for far-off resonant Raman scattering processes. However, as demonstrated in this study, we have found that this widely accepted long-standing assumption fails drastically for totally symmetric vibration modes of molecules in general off-resonant Raman scattering. Perturbed first-principles calculations for water molecule show that strong constructive interference between the A and B terms occurs for the Raman intensity of the symmetric O-H stretching mode, which can account for ∼40% of the total intensity. Meanwhile, a minor destructive interference is found for the angle bending mode. The state-to-state mapping between Albrecht's theory and perturbation theory allows us to verify the accuracy of the widely employed perturbation method for the dynamic/resonant Raman intensities. The model calculations rationalized from water molecule with the bending mode show that the perturbation method is a good approximation only when the absolute energy difference between the first excited state and the incident light is more than five times greater than the vibrational energy in the ground state.

  18. Playing fair: the contribution of high-functioning recess to overall school climate in low-income elementary schools. (United States)

    London, Rebecca A; Westrich, Lisa; Stokes-Guinan, Katie; McLaughlin, Milbrey


    Recess is a part of the elementary school day with strong implications for school climate. Positive school climate has been linked to a host of favorable student outcomes, from attendance to achievement. We examine 6 low-income elementary schools' experiences implementing a recess-based program designed to provide safe, healthy, and inclusive play to study how improving recess functioning can affect school climate. Data from teacher, principal, and recess coach interviews; student focus groups; recess observations; and a teacher survey are triangulated to understand the ways that recess changed during implementation. Comparing schools that achieved higher- and lower-functioning recesses, we link recess functioning with school climate. Recess improved in all schools, but 4 of the 6 achieved a higher-functioning recess. In these schools, teachers and principals agreed that by the end of the year, recess offered opportunities for student engagement, conflict resolution, pro-social skill development, and emotional and physical safety. Respondents in these four schools linked these changes to improved overall school climate. Recess is an important part of the school day for contributing to school climate. Creating a positive recess climate helps students to be engaged in meaningful play and return to class ready to learn. © 2014, American School Health Association.

  19. Genetic variation in VEGF does not contribute significantly to the risk of congenital cardiovascular malformation.

    Directory of Open Access Journals (Sweden)

    Helen R Griffin

    Full Text Available Several previous studies have investigated the role of common promoter variants in the vascular endothelial growth factor (VEGF gene in causing congenital cardiovascular malformation (CVM. However, results have been discrepant between studies and no study to date has comprehensively characterised variation throughout the gene. We genotyped 771 CVM cases, of whom 595 had the outflow tract malformation Tetralogy of Fallot (TOF, and carried out TDT and case-control analyses using haplotype-tagging SNPs in VEGF. We carried out a meta-analysis of previous case-control or family-based studies that had typed VEGF promoter SNPs, which included an additional 570 CVM cases. To identify rare variants potentially causative of CVM, we carried out mutation screening in all VEGF exons and splice sites in 93 TOF cases. There was no significant effect of any VEGF haplotype-tagging SNP on the risk of CVM in our analyses of 771 probands. When the results of this and all previous studies were combined, there was no significant effect of the VEGF promoter SNPs rs699947 (OR 1.05 [95% CI 0.95-1.17]; rs1570360 (OR 1.17 [95% CI 0.99-1.26]; and rs2010963 (OR 1.04 [95% CI 0.93-1.16] on the risk of CVM in 1341 cases. Mutation screening of 93 TOF cases revealed no VEGF coding sequence variants and no changes at splice consensus sequences. Genetic variation in VEGF appears to play a small role, if any, in outflow tract CVM susceptibility.

  1. Factors Contributing to the Subjective Career Success among Islamic Educators in Primary Schools

    Directory of Open Access Journals (Sweden)

    Mesnan Supa`ad


    Full Text Available A very limited research has been done in the field of career development among Islamic education teachers. Most of the previous researches showed an improvement in terms of grades, positions, and responsibilities of their previous routines as an indicator of their career advancement. However, this conceptual (concept paper discusses how personality factors, career planning, and career strategy can provide significant contribution to the success of Islamic education teachers’ career. Based on the Five Factor Model, Gould Planning Model, and the support of previous researches, this paper discusses how these three factors can contribute to the success of Islamic education teachers’ career. This paper also discusses its impact towards Islamic education teachers in Malaysia, schools management, District Education Office, Ministry of Education, and teachers education institutions.

  6. Food and drink consumption at school lunchtime: the impact of lunch type and contribution to overall intake in British 9-10-year-old children. (United States)

    Harrison, Flo; Jennings, Amy; Jones, Andy; Welch, Ailsa; van Sluijs, Esther; Griffin, Simon; Cassidy, Aedín


    To examine the differences in dietary intakes of children consuming school meals and packed lunches, the contribution of lunchtime intake to overall dietary intake, and how lunchtime intake relates to current food-based recommendations for school meals. Cross-sectional analysis of overall intake of macronutrients and food choice from 4 d food diaries and school lunchtime intake from the two diary days completed while at school. Norfolk, UK. One thousand six hundred and twenty-six children (aged 9-10 years) attending ninety Norfolk primary schools. At school, lunchtime school meal eaters consumed more vegetables, sweet snacks, chips, starchy foods and milk, and less squash/cordial, fruit, bread, confectionery and savoury snacks than packed lunch eaters. These differences were also reflected in the overall diet. On average school meal eaters met the School Food Trust (SFT) food-based standards, while food choices among packed lunch eaters were less healthy. The contribution of food consumed at school lunchtime to overall diet varied by food and lunch type, ranging from 0.8 % (milk intake in packed lunches) to 74.4 % (savoury snack intake in packed lunches). There were significant differences in the foods consumed by school meal and packed lunch eaters, with food choices among school meal eaters generally in line with SFT standards. The food choices made at school lunchtime make a significant contribution to overall diet.

  8. School climate factors contributing to student and faculty perceptions of safety in select Arizona schools. (United States)

    Bosworth, Kris; Ford, Lysbeth; Hernandaz, Diley


    To ensure that schools are safe places where students can learn, researchers and educators must understand student and faculty safety concerns. This study examines student and teacher perceptions of school safety. Twenty-two focus groups with students and faculty were conducted in 11 secondary schools. Schools were selected from a stratified sample to vary in location, proximity to Indian reservations, size, and type. The data analysis was based on grounded theory. In 9 of 11 schools, neither faculty nor students voiced overwhelming concerns about safety. When asked what makes school safe, students tended to report physical security features. School climate and staff actions also increased feelings of safety. Faculty reported that relationships and climate are key factors in making schools safe. High student performance on standardized tests does not buffer students from unsafe behavior, nor does living in a dangerous neighborhood necessarily lead to more drug use or violence within school walls. School climate seemed to explain the difference between schools in which students and faculty reported higher versus lower levels of violence and alcohol and other drug use. The findings raise provocative questions about school safety and provide insight into elements that lead to perceptions of safety. Some schools have transcended issues of location and neighborhood to provide an environment perceived as safe. Further study of those schools could provide insights for policy makers, program planners, and educational leaders. © 2011, American School Health Association.

  10. The contribution of human agricultural activities to increasing evapotranspiration is significantly greater than climate change effect over Heihe agricultural region. (United States)

    Zou, Minzhong; Niu, Jun; Kang, Shaozhong; Li, Xiaolin; Lu, Hongna


    Evapotranspiration (ET) is a major component linking the water, energy, and carbon cycles. Understanding changes in ET and the relative contribution rates of human activity and of climate change at the basin scale is important for sound water resources management. In this study, changes in ET in the Heihe agricultural region in northwest China during 1984-2014 were examined using remotely-sensed ET data with the Soil and Water Assessment Tool (SWAT). Correlation analysis identified the dominant factors that influence change in ET per unit area and those that influence change in total ET. Factor analysis identified the relative contribution rates of the dominant factors in each case. The results show that human activity, which includes factors for agronomy and irrigation, and climate change, including factors for precipitation and relative humidity, both contribute to increases in ET per unit area at rates of 60.93% and 28.01%, respectively. Human activity, including the same factors, and climate change, including factors for relative humidity and wind speed, contribute to increases in total ET at rates of 53.86% and 35.68%, respectively. Overall, in the Heihe agricultural region, the contribution of human agricultural activities to increased ET was significantly greater than that of climate change.

  13. Using Hierarchical Linear Modeling to Examine How Individual SLPs Differentially Contribute to Children's Language and Literacy Gains in Public Schools. (United States)

    Farquharson, Kelly; Tambyraja, Sherine R; Logan, Jessica; Justice, Laura M; Schmitt, Mary Beth


    The purpose of this study was twofold: (a) to determine the unique contributions in children's language and literacy gains, over 1 academic year, that are attributable to the individual speech-language pathologist (SLP) and (b) to explore possible child- and SLP-level factors that may further explain SLPs' contributions to children's language and literacy gains. Participants were 288 kindergarten and 1st-grade children with language impairment who were currently receiving school-based language intervention from SLPs. Using hierarchical linear modeling, we partitioned the variance in children's gains in language (i.e., grammar, vocabulary) and literacy (i.e., word decoding) that could be attributed to their individual SLP. Results revealed a significant contribution of individual SLPs to children's gains in grammar, vocabulary, and word decoding. Children's fall language scores and grade were significant predictors of SLPs' contributions, although no SLP-level predictors were significant. The present study makes a first step toward incorporating implementation science and suggests that, for children receiving school-based language intervention, variance in child language and literacy gains in an academic year is at least partially attributable to SLPs. Continued work in this area should examine the possible SLP-level characteristics that may further explicate the relative contributions of SLPs.

  14. Selective excretion of IgA in rat bronchial secretions: lack of significant contribution from plasma IgA

    International Nuclear Information System (INIS)

    Lemaitre-Coelho, I.; Yamakido, M.; Montgomery, P.C.; Langendries, A.E.; Vaerman, J.P.


    Concentrated rat bronchial washings (BW) were analyzed by gel-filtration and immunochemical methods. BW contained mainly albumin, transferrin and IgG. Free secretory component and secretory IgA were identified in BW; the BW-IgA had the same three sedimentation coefficients, i.e. +/- 11 S, 13 S, 15 S by sucrose density gradient ultracentrifugation, as rat milk and rat bile IgA; the three peaks were secretory IgA. Compared to serum, and relatively to albumin, BW were significantly enriched in IgA, although much less than rat bile. Purified polyclonal rat polymeric 125 I-IgA was injected intravenously into normal rats, and into rats with bile duct ligation or partial hepatectomy, which decrease the liver plasma-to-bile transfer of IgA. BW were then collected, one or four hours later, to assess the recovery of the 125 I-IgA in BW and to estimate the contribution of serum IgA to BW-IgA. Very little 125 I-IgA (less than 0.2%) was recovered in all BW. The specific activity, measured only in the rat with the highest recovery in BW, was 20 times lower in BW than in serum. The data demonstrate that rat serum IgA does not contribute significantly to IgA in BW

  15. Significant contribution of stacking faults to the strain hardening behavior of Cu-15%Al alloy with different grain sizes. (United States)

    Tian, Y Z; Zhao, L J; Chen, S; Shibata, A; Zhang, Z F; Tsuji, N


    It is commonly accepted that twinning can induce an increase of strain-hardening rate during the tensile process of face-centered cubic (FCC) metals and alloys with low stacking fault energy (SFE). In this study, we explored the grain size effect on the strain-hardening behavior of a Cu-15 at.%Al alloy with low SFE. Instead of twinning, we detected a significant contribution of stacking faults (SFs) irrespective of the grain size even in the initial stage of tensile process. In contrast, twinning was more sensitive to the grain size, and the onset of deformation twins might be postponed to a higher strain with increasing the grain size. In the Cu-15 at.%Al alloy with a mean grain size of 47 μm, there was a stage where the strain-hardening rate increases with strain, and this was mainly induced by the SFs instead of twinning. Thus in parallel with the TWIP effect, we proposed that SFs also contribute significantly to the plasticity of FCC alloys with low SFE.

The research hypothesizes that there might be a synergistic interaction between the two. In other words if organic strategies and procurement schemes have the pote...

  18. The cosmopolitan maternal heritage of the Thoroughbred racehorse breed shows a significant contribution from British and Irish native mares. (United States)

    Bower, M A; Campana, M G; Whitten, M; Edwards, C J; Jones, H; Barrett, E; Cassidy, R; Nisbet, R E R; Hill, E W; Howe, C J; Binns, M


    The paternal origins of Thoroughbred racehorses trace back to a handful of Middle Eastern stallions, imported to the British Isles during the seventeenth century. Yet, few details of the foundation mares were recorded, in many cases not even their names (several different maternal lineages trace back to 'A Royal Mare'). This has fuelled intense speculation over their origins. We examined mitochondrial DNA from 1929 horses to determine the origin of Thoroughbred foundation mares. There is no evidence to support exclusive Arab maternal origins as some historical records have suggested, or a significant importation of Oriental mares (the term used in historic records to refer to Middle East and western Asian breeds including Arab, Akhal-Teke, Barb and Caspian). Instead, we show that Thoroughbred foundation mares had a cosmopolitan European heritage with a far greater contribution from British and Irish Native mares than previously recognized.

  20. Smoking cessation programmes in radon affected areas: can they make a significant contribution to reducing radon-induced lung cancers?

    International Nuclear Information System (INIS)

    Denman, A.R.; Groves-Kirkby, C.J.; Timson, K.; Shield, G.; Rogers, S.; Phillips, P.S.


    Domestic radon levels in parts of the UK are sufficiently high to increase the risk of lung cancer in the occupants. Public health campaigns in Northamptonshire, a designated radon affected area with 6.3% of homes having average radon levels over the UK action level of 200 Bq m -3 , have encouraged householders to test for radon and then to carry out remediation in their homes, but have been only partially successful. Only 40% of Northamptonshire houses have been tested, and only 15% of householders finding raised levels proceed to remediate. Of those who did remediate, only 9% smoked, compared to a countywide average of 28.8%. This is unfortunate, since radon and smoking combine to place the individual at higher risk by a factor of around 4, and suggests that current strategies to reduce domestic radon exposure are not reaching those most at risk. During 2004-5, the NHS Stop Smoking Services in Northamptonshire assisted 2,808 smokers to quit to the 4-week stage, with some 30% of 4-week quitters remaining quitters at 1 year. We consider whether smoking cessation campaigns make significant contributions to radon risk reduction on their own, by assessing individual occupants' risk of developing lung cancer from knowledge of their age, gender, and smoking habits, together with he radon level in their house. The results demonstrate that smoking cessation programmes have significant added value in radon affected areas, and contribute a greater health benefit than reducing radon levels in the smokers' homes, whilst they remain smokers. Additionally, results are presented from a questionnaire-based survey of quitters, addressing their reasons for seeking help in quitting smoking, and whether knowledge of radon risks influenced this decision. The impact of these findings on future public health campaigns to reduce the impact of radon and smoking are discussed. (author)

  7. HMGB1 and Extracellular Histones Significantly Contribute to Systemic Inflammation and Multiple Organ Failure in Acute Liver Failure. (United States)

    Yang, Runkuan; Zou, Xiaoping; Tenhunen, Jyrki; Tønnessen, Tor Inge


    Acute liver failure (ALF) is the culmination of severe liver cell injury from a variety of causes. ALF occurs when the extent of hepatocyte death exceeds the hepatic regenerative capacity. ALF has a high mortality that is associated with multiple organ failure (MOF) and sepsis; however, the underlying mechanisms are still not clear. Emerging evidence shows that ALF patients/animals have high concentrations of circulating HMGB1, which can contribute to multiple organ injuries and mediate gut bacterial translocation (BT). BT triggers/induces systemic inflammatory responses syndrome (SIRS), which can lead to MOF in ALF. Blockade of HMGB1 significantly decreases BT and improves hepatocyte regeneration in experimental acute fatal liver injury. Therefore, HMGB1 seems to be an important factor that links BT and systemic inflammation in ALF. ALF patients/animals also have high levels of circulating histones, which might be the major mediators of systemic inflammation in patients with ALF. Extracellular histones kill endothelial cells and elicit immunostimulatory effect to induce multiple organ injuries. Neutralization of histones can attenuate acute liver, lung, and brain injuries. In conclusion, HMGB1 and histones play a significant role in inducing systemic inflammation and MOF in ALF.

  9. Do health care workforce, population, and service provision significantly contribute to the total health expenditure? An econometric analysis of Serbia. (United States)

    Santric-Milicevic, M; Vasic, V; Terzic-Supic, Z


    In times of austerity, the availability of econometric health knowledge assists policy-makers in understanding and balancing health expenditure with health care plans within fiscal constraints. The objective of this study is to explore whether the health workforce supply of the public health care sector, population number, and utilization of inpatient care significantly contribute to total health expenditure. The dependent variable is the total health expenditure (THE) in Serbia from the years 2003 to 2011. The independent variables are the number of health workers employed in the public health care sector, population number, and inpatient care discharges per 100 population. The statistical analyses include the quadratic interpolation method, natural logarithm and differentiation, and multiple linear regression analyses. The level of significance is set at P Total health expenditure increased by 1.21 standard deviations, with an increase in health workforce growth rate by 1 standard deviation. Furthermore, this rate decreased by 1.12 standard deviations, with an increase in (negative) population growth rate by 1 standard deviation. Finally, the growth rate increased by 0.38 standard deviation, with an increase of the growth rate of inpatient care discharges per 100 population by 1 standard deviation (P < 0.001). Study results demonstrate that the government has been making an effort to control strongly health budget growth. Exploring causality relationships between health expenditure and health workforce is important for countries that are trying to consolidate their public health finances and achieve universal health coverage at the same time.

    To explore how men's Significant Others (SOs), including family members and close friends, contribute to the uptake and maintenance of specific CAM therapies. This study was the second, qualitative phase of a mixed-methods project investigating the use of CAM in an Australian male cancer population. Male participants were purposefully selected from a pool of 403 patients who answered a survey in the first quantitative phase (94% response rate and 86% consent rate for follow-up interview). Then semi-structured interviews among 26 men with a variety of cancers and 24 SOs were conducted. All 43 interviews were recorded, transcribed, and analysed thematically. Men used CAM/Natural products to cope with physical concerns, and this was actively supported by men's SOs who contributed to the uptake and maintenance of these CAMs. The shared CAM preparation and consumption functioned to strengthen the bond between men and their SOs, and also helped men's SOs to cope with uncertainty and regain control. In contrast, men practiced CAM/Mind-body medicine to receive emotional benefits, and only rarely shared this practice with their SOs, indicating a need for coping with emotions in a private way. Men's CAM use is a multifaceted process that can be better understood by considering CAM categories separately. CAM/Natural products help men to cope with physical concerns, while CAM/Mind-body medicine assist men to cope with their emotions in a private way. Oncology professionals can use this information to better promote and implement integrative cancer care services. Copyright © 2014 Elsevier Ltd. All rights reserved.

  12. Climatic fluctuations as a significant contributing factor for volcanic collapses. Evidence from Mexico during the Late Pleistocene (United States)

    Capra, L.; Bernal-Uruchurtu, J. P.; Carrasco, G.


    Climate oscillations have significantly contributed to the planet's evolution, including volcanic activity. Major glaciations have been considered not only as a triggering mechanism for large magmatic eruptions but also inducing volcano instability. Generally, volcano instability can be inferred from detailed volcanological and structural studies of a volcano and its associated depositional sequence, but the triggering mechanism has been always difficult to infer. In this paper, we present evidence of how climatic variations during the Late Pleistocene could have forced sector collapses of the main Mexican stratovolcanoes and enhanced the mobility of associated massive flows inducing the transformation of debris avalanche into debris flows. In particular, the climatic record based on atmospheric moisture content from robustly dated lake record from Guatemala and a U/Th dated speleothem from New Mexico are used here as indicators of summer and winter precipitation. Depositional sequences associated with Late Pleistocene sector collapses of Volcan de Colima, Nevado de Toluca, Citlaltepetl (Pico de Orizaba) and Cofre de Perote volcanoes are here analyzed. Comparing the timing of the event with the climatic record, a combination of summer and/or winter pluvial conditions could have forced and triggered the failure of already unstable volcanoes, even during glacier advances (as for the Citlaltepetl event). Independently of the main cause of the volcano instability (magmatic or tectonic) it is important to highlight that the climatic factor played an important role in enhancing the volcano instability and promoted the lateral transformation of debris avalanches, which under dry conditions would have affected more limited areas.

    Al-Bitar, Zaid B; Al-Omari, Iyad K; Sonbol, Hawazen N; Al-Ahmad, Hazem T; Cunningham, Susan J


    The aims of this study were to investigate the experience of bullying in a representative sample of Jordanian schoolchildren in Amman, to look at its effect on school attendance and perception of academic performance, and to look at the contribution of general physical and dentofacial features to this phenomenon. This was a cross-sectional study in which a representative sample of sixth-grade students (11-12 years of age) from randomly selected schools was asked to complete questionnaires distributed in the classroom in the presence of the researchers. The final sample size was 920 children (470 girls, 450 boys). The prevalence of bullying was 47% (n = 433); significantly more boys reported being bullied than girls (P bullying reported playing truant from school and disliking school than those who were not bullied. Teeth were the number 1 feature targeted for bullying, followed by strength and weight. The 3 most commonly reported dentofacial features targeted by bullies were spacing between the teeth or missing teeth, shape or color of the teeth, and prominent maxillary anterior teeth. This study demonstrated a high prevalence of bullying in Jordanian schools, with many children experiencing bullying because of their dental or facial appearance.

  14. Contribution of health motive to cannabis use among high-school students. (United States)

    Chabrol, Henri; Beck, Charline; Laconi, Stéphanie


    The Marijuana Motives Measure (MMM), which is derived from a scale measuring alcohol use motives, has been the main instrument used to explore the role of motives in cannabis use and related problems. Two studies attempted to developed specific cannabis use motives but none of them showed a unique association to cannabis use and problems when controlling for MMM motives. The aim of our study was to examine if additional motives contributed to problematic use beyond MMM motives and psychopathological symptoms. Participants were 249 high-school students who completed the Cannabis Use Disorder Identification Test-Revised (CUDIT-R) assessing cannabis use and problematic use, the MMM and a new scale measuring motives derived from clinical experience with adolescents using cannabis (CED motives), and scales measuring anxiety and depressive symptoms and borderline personality traits. Among the 107 participants using cannabis, 39 reached the cut-off score for problematic cannabis use. Hierarchical multiple regression analyses controlling for psychopathological variables showed that only one CED motives, Health (sleep, form, energy, appetite, health), was a significant predictor of both frequency of use and problematic use symptoms. The importance of Health motive may be linked to the role of depressive symptoms and may have implication for treatment. We suggest to add the Health subscale to the MMM and to further study the role of health motive in both use and dependence. Copyright © 2016. Published by Elsevier Ltd.

    Full Text Available Introduction: the problem of organizing students’ independent work/self-study is not new, but the changes in the higher school for the last two decades show that the experience accumulated in the traditional educational model can be applied only when it is processed in the present-day conditions. The article analyses the innovative component of the educational process in terms of a significant increase in the volume of compulsory independent work in the university. Particular attention is paid to determining the levels of the formation of skills for independent work in terms of students’ readiness for its implementa¬tion. The aim of the research is to identify the most significant skills of independent work for successful study at the university. Materials and Methods: the research is based on general scholarly methods: analysis, comparison, generalisation. A questionnaire survey was carried out and a correlation analysis of the results was presented. The mathematical statistics methods in Excel application were u sed for processing the survey data. Results: the article focused on the relevance of formation the students’ ability to work independently in the learning process. Requirements for professionals recognize the need for knowledge and skills, but more importantly, the ability and readiness to complete this knowledge and be in a state of continuous education and self-education. In turn, readiness to self-education cannot exist without independent work. The ratio of students to work independently and their skills’ levels in this area of the gnostic, design, structural, organisational and communicative blocks were identified because o f the research. Discussion and Conclusions: the levels of the formation of the skills for independent work influence on the success of the learning. There is a correlation between indicators of achievement and the ability to work independently. Organisation and communication skills have significant

  16. Factors significantly related to science achievement of Malaysian middle school students: An analysis of TIMSS 1999 data (United States)

    Mokshein, Siti Eshah

    The importance of science and technology in the global economy has led to growing emphasis on math and science achievement all over the world. In this study, I seek to identify variables at the student-level and school-level that account for the variation in science achievement of the eighth graders in Malaysia. Using the Third International Math and Science Study (TIMSS) 1999 for Malaysia, a series of HLM analysis was performed. Results indicate that (1) variation in overall science achievement is greater between schools than within schools; (2) both the selected student-level and school-level factors are Important in explaining the variation in the eight graders' achievement In science; (3) the selected student-level variables explain about 13% of the variation in students' achievement within schools, but as an aggregate, they account for a much larger proportion of the between-school variance; (4) the selected school-level variables account for about 55% of the variation between schools; (5) within schools, the effects of self-concept In science, awareness of the social implications of science, gender, and home educational resources are significantly related to achievement; (6) the effects of self-concept in science and awareness of social implications of science are significant even after controlling for the effects of SES; (7) between schools, the effects of the mean of home educational resources, mean of parents' education, mean of awareness of the social implications of science, and emphasis on conducting experiments are significantly related to achievement; (8) the effects of SES variables explain about 50% of the variation in the school means achievement; and (9) the effects of emphasis on conducting experiments on achievement are significant even after controlling for the effects of SES. Since it is hard to change the society, it is recommended that efforts to Improve science achievement be focused more at the school-level, concentrating on variables that

    Full Text Available In present life conditions, especially in urban environment, children have very poor conditions for physical activities, or for movement in general. According to the new researches, working conditions and quality of work in nurseries and schools, especially if they are related to physical exercises, have certain influences on overall development of pre-school and school children. Childhood is ideal time for correction of numerous postural disturbances and deformities, whether they are congenital or acquired by injury, wrong body posture, or by poor nutrition. Playing is a power fultool for directing correct development of children, so very of ten it has to be adapted to age, capabilities, interests and needs of children.

  20. Factors Contributing to Sexual Violence at Selected Schools for Learners with Mild Intellectual Disability in South Africa. (United States)

    Nyokangi, Doris; Phasha, Nareadi


    This paper reports part of the findings of a study which exposed sexual violence in schools for learners with mild intellectual disability in South Africa. Special attention was paid on factors contributing to such a problem. Data were collected using focus groups and individual interviews with 16 learners with mild intellectual disability at two special schools in South Africa. This was followed by individual interviews with the school nurse and social worker, and an analysis of schools' books of incidents. Factors contributing to sexual violence at schools for learners with mild intellectual disability included: (i) peer pressure, (ii) concealment of reported incidents of sexual violence, (iii) unsupervised areas linked to schools and (iv) arranged relationships. The following suggestions are put forth: (i) awareness programmes, (ii) sensitization of teachers about the consequences and prevention of sexual violence, (iii) boundaries within which the arranged relationship occurs, (iv) intensification of sexuality education and (v) supervision around the school premises. © 2015 John Wiley & Sons Ltd.

    Full Text Available This article presents the results of a research professional, which was developed in the context of the early years of elementary school, from the application of a didactic sequence, with a view to initiation of scientific literacy of students in the literacy process of language. The methodological approach was qualitative, interpretative nature. The subjects were the students of 1st year 1st Cycle of Basic Education in a public school in Ponta Grossa - PR. The data were collected through observation, application of diagnostic testing, audio recordings, photographs, written records, illustrations and posttest. The theory History Cultural Development made the analysis of pedagogical actions and reflections on them. The main results indicate that the activities of the instructional sequence, contributed to the progressive advancement of the students' knowledge in relation to the area of science and basic scientific literacy, and also contributed to make learning the language more contextualized and interdisciplinary. It is noted that this work requires a teacher to assume the role of mediator between the scientific and the children, as well as requires the understanding that, as the subject entered the technological means, students in the early years have a right to access scientific culture. In this perspective, respecting the level of development of the children, the teacher can provide challenges and mediations necessary for the gradual construction of scientific knowledge, the first years of elementary school.

    Full Text Available This small-scale study sought to determine the factors that contribute to use ofdrugs by male adolescents in South African public secondary schools. The studywas conducted in four secondary schools in Zeerust, North West, a province ofSouth Africa. Purposive sampling was employed to select from the secondaryschools 12 male adolescents who were prone to substance abuse problems. Aqualitative research approach was followed underpinned by the interpretiveresearch paradigm. More specifically, a multiple case research design was used.The study was successful in identifying the most commonly used drugs such asalcohol, nicotine, cannabis, and heroin. These drugs are readily available in thesurrounding communities and are affordable to the learners. Socialand economicfactors are the main factors contributing to the use of drugs among maleadolescents. The way in which children are brought up, who they associate withand whether they have access to money to buy the drugs largely contribute to druguse. Thisstudy concludes by proposing mitigation strategies that can be employedto deal with substance abuse scourge before it escalates further. Furthermore, thestudy identifies a need for involvement of various stakeholders to find a solutionto the substanceabuse problem.

  12. The contribution of school to the feeling of acceptance and the risk of suicide attempts among Austrian gay and bisexual males. (United States)

    Plöderl, Martin; Faistauer, Gregor; Fartacek, Reinhold


    School-related factors contributing to the suicidality of lesbian, gay, and bisexual individuals are understudied, especially in German-speaking Europe. Among our Web-based sample of 468 Austrian gay or bisexual adults, 18% attempted suicide and about one half of them reported that hard times at school related to one's homosexuality partly or mainly caused the attempt. Such suicide attempts were associated with a lack of acceptance at school and harassment experiences. In contrast to suicide attempts, acceptance at school was significantly associated with protective factors such as teachers intervening against homophobia or presence of openly homosexual teachers or peers. These findings may be important for consideration in school-based suicide prevention programs.

    Purificacion eLopez-Garcia


    Full Text Available Cyanobacteria are thought to play a key role in carbonate formation due to their metabolic activity, but other organisms carrying out oxygenic photosynthesis (photosynthetic eukaryotes or other metabolisms (e.g. anoxygenic photosynthesis, sulfate reduction, may also contribute to carbonate formation. To obtain more quantitative information than that provided by more classical PCR-dependent methods, we studied the microbial diversity of microbialites from the Alchichica crater lake (Mexico by mining for 16S/18S rRNA genes in metagenomes obtained by direct sequencing of environmental DNA. We studied samples collected at the Western (AL-W and Northern (AL-N shores of the lake and, at the latter site, along a depth gradient (1, 5, 10 and 15 m depth. The associated microbial communities were mainly composed of bacteria, most of which seemed heterotrophic, whereas archaea were negligible. Eukaryotes composed a relatively minor fraction dominated by photosynthetic lineages, diatoms in AL-W, influenced by Si-rich seepage waters, and green algae in AL-N samples. Members of the Gammaproteobacteria and Alphaproteobacteria classes of Proteobacteria, Cyanobacteria and Bacteroidetes were the most abundant bacterial taxa, followed by Planctomycetes, Deltaproteobacteria (Proteobacteria, Verrucomicrobia, Actinobacteria, Firmicutes and Chloroflexi. Community composition varied among sites and with depth. Although cyanobacteria were the most important bacterial group contributing to the carbonate precipitation potential, photosynthetic eukaryotes, anoxygenic photosynthesizers and sulfate reducers were also very abundant. Cyanobacteria affiliated to Pleurocapsales largely increased with depth. Scanning electron microscopy (SEM observations showed considerable areas of aragonite-encrusted Pleurocapsa-like cyanobacteria at microscale. Multivariate statistical analyses showed a strong positive correlation of Pleurocapsales and Chroococcales with aragonite formation at

    Laine, Sari; Saaranen, Terhi; Pertel, Tiia; Hansen, Siivi; Lepp, Kädi; Tossavainen, Kerttu


    This article is part of a long term project "Promoting the Occupational Well-Being of School Staff-Action Research Project in Finland and Estonia, 2009-2014." The purpose of this article is to describe the significance of action plans in the promotion of the occupational well-being of primary and upper secondary school staff in Finland and Estonia from 2010 to the turn of the year 2011-2012. An electronic open questionnaire was sent to occupational well-being groups in Finland (N=18) and in Estonia (N=39). In Finland, the questionnaire was responded to by 16 (n=16) occupational well-being groups, and in Estonia, by 38 (n=38) groups. The qualitative data were analyzed using the inductive-deductive method and content analysis. The obtained results indicate that the schools had named goals for action plans in all aspects of the promotion of occupational well-being in schools (worker and work, working conditions, professional competence, working community) and that these goals were mainly realized in the schools in a systematic way. Schools felt that the action plan for occupational well-being helped them to set goals for occupational well-being and that the planned actions were realized in a more systematic way than before.

  18. Contributions of After School Programs to the Development of Fundamental Movement Skills in Children. (United States)

    Burrows, E Jean; Keats, Melanie R; Kolen, Angela M

    Fundamental movement skill (FMS) proficiency or the ability to perform basic skills (e.g., throwing, catching and jumping) has been linked to participation in lifelong physical activity. FMS proficiency amongst children has declined in the previous 15 years, with more children performing FMS at a low-mastery level. These declines may help explain the insufficient levels of participation in health promoting physical activity seen in today's youth. The after school time period (e.g., 3 to 6 p.m.), is increasingly considered an opportune time for physical activity interventions. To date, little research has examined the potential for after school programming to improve FMS proficiency. Participants (n=40, 6-10 years) of two existent physical activity based after school programs, a low-organized games and a sports-based program, were pre- and post-tested for FMS proficiency using the Test of Gross Motor Development-2 (TGMD-2) over an 11-week period. The sports-based program participants showed no improvement in FMS over the 11-week study ( p =0.91, eta 2 =0.00) and the games-based program participants significantly improved their proficiency ( p =0.00, eta 2 =0.30). No significant ( p =0.13, eta 2 = 0.06), differences were found in change in FMS scores between the low-organized games program participants and the sport-based program participants. These results suggest that after school programs with a low-organized games-based focus may support a moderate improvement in FMS proficiency in young children. Better training of after school program leaders on how to teach FMS may be necessary to assist children in acquiring sufficient proficiency in FMS.

  19. De novo fatty acid biosynthesis contributes significantly to establishment of a bioenergetically favorable environment for vaccinia virus infection.

    Directory of Open Access Journals (Sweden)

    Matthew D Greseth


    Full Text Available The poxvirus life cycle, although physically autonomous from the host nucleus, is nevertheless dependent upon cellular functions. A requirement for de novo fatty acid biosynthesis was implied by our previous demonstration that cerulenin, a fatty acid synthase inhibitor, impaired vaccinia virus production. Here we show that additional inhibitors of this pathway, TOFA and C75, reduce viral yield significantly, with partial rescue provided by exogenous palmitate, the pathway's end-product. Palmitate's major role during infection is not for phospholipid synthesis or protein palmitoylation. Instead, the mitochondrial import and β-oxidation of palmitate are essential, as shown by the impact of etomoxir and trimetazidine, which target these two processes respectively. Moreover, the impact of these inhibitors is exacerbated in the absence of exogenous glucose, which is otherwise dispensable for infection. In contrast to glucose, glutamine is essential for productive viral infection, providing intermediates that sustain the TCA cycle (anaplerosis. Cumulatively, these data suggest that productive infection requires the mitochondrial β-oxidation of palmitate which drives the TCA cycle and energy production. Additionally, infection causes a significant rise in the cellular oxygen consumption rate (ATP synthesis that is ablated by etomoxir. The biochemical progression of the vaccinia life cycle is not impaired in the presence of TOFA, C75, or etomoxir, although the levels of viral DNA and proteins synthesized are somewhat diminished. However, by reversibly arresting infections at the onset of morphogenesis, and then monitoring virus production after release of the block, we determined that virion assembly is highly sensitive to TOFA and C75. Electron microscopic analysis of cells released into C75 revealed fragmented aggregates of viroplasm which failed to be enclosed by developing virion membranes. Taken together, these data indicate that vaccinia

    Energy Technology Data Exchange (ETDEWEB)

    Williams, Paul T.


    Although cross-sectional studies show active individuals areleaner than their sedentary counterparts, it remains to be determined towhat extent this is due to initially leaner men and women choosing toexercise longer and more intensely (self-selection bias). In this reportwalking volume (weekly distance) and intensity (speed) were compared tocurrent BMI (BMIcurrent) and BMI at the start of walking (BMIstarting) in20,353 women and 5,174 men who had walked regularly for exercise for 7.2and 10.6 years,respectively. The relationships of BMIcurrent andBMIstarting with distance and intensity were nonlinear (convex). Onaverage, BMIstarting explained>70 percent of the association betweenBMIcurrent and intensity, and 40 percent and 17 percent of theassociation between BMIcurrent and distance in women and men,respectively. Although the declines in BMIcurrent with distance andintensity were greater among fatter than leaner individuals, the portionsattributable to BMIstarting remained relatively constant regardless offatness. Thus self-selection bias accounts for most of the decline in BMIwith walking intensity and smaller albeit significant proportions of thedecline with distance. This demonstration of self-selection is germane toother cross-sectional comparisons in epidemiological research, givenself-selection is unlikely to be limited to weight or peculiar tophysical activity.

  3. Dermal exposure to jet fuel JP-8 significantly contributes to the production of urinary naphthols in fuel-cell maintenance workers. (United States)

    Chao, Yi-Chun E; Kupper, Lawrence L; Serdar, Berrin; Egeghy, Peter P; Rappaport, Stephen M; Nylander-French, Leena A


    Jet propulsion fuel 8 (JP-8) is the major jet fuel used worldwide and has been recognized as a major source of chemical exposure, both inhalation and dermal, for fuel-cell maintenance workers. We investigated the contributions of dermal and inhalation exposure to JP-8 to the total body dose of U.S. Air Force fuel-cell maintenance workers using naphthalene as a surrogate for JP-8 exposure. Dermal, breathing zone, and exhaled breath measurements of naphthalene were obtained using tape-strip sampling, passive monitoring, and glass bulbs, respectively. Levels of urinary 1- and 2-naphthols were determined in urine samples and used as biomarkers of JP-8 exposure. Multiple linear regression analyses were conducted to investigate the relative contributions of dermal and inhalation exposure to JP-8, and demographic and work-related covariates, to the levels of urinary naphthols. Our results show that both inhalation exposure and smoking significantly contributed to urinary 1-naphthol levels. The contribution of dermal exposure was significantly associated with levels of urinary 2-naphthol but not with urinary 1-naphthol among fuel-cell maintenance workers who wore supplied-air respirators. We conclude that dermal exposure to JP-8 significantly contributes to the systemic dose and affects the levels of urinary naphthalene metabolites. Future work on dermal xenobiotic metabolism and toxicokinetic studies are warranted in order to gain additional knowledge on naphthalene metabolism in the skin and the contribution to systemic exposure.

  4. Endotoxin levels and contribution factors of endotoxins in resident, school, and office environments - A review (United States)

    Salonen, Heidi; Duchaine, Caroline; Létourneau, Valérie; Mazaheri, Mandana; Laitinen, Sirpa; Clifford, Sam; Mikkola, Raimo; Lappalainen, Sanna; Reijula, Kari; Morawska, Lidia


    As endotoxin exposure has known effects on human health, it is important to know the generally existing levels of endotoxins as well as their contributing factors. This work reviews current knowledge on the endotoxin loads in settled floor dust, concentrations of endotoxins in indoor air, and different environmental factors potentially affecting endotoxin levels. The literature review consists of peer-reviewed manuscripts located using Google and PubMed, with search terms based on individual words and combinations. References from relevant articles have also been searched. Analysis of the data showed that in residential, school, and office environments, the mean endotoxin loads in settled floor dust varied between 660 and 107,000 EU/m2, 2180 and 48,000 EU/m2, and 2700 and 12,890 EU/m2, respectively. Correspondingly, the mean endotoxin concentrations in indoor air varied between 0.04 and 1610 EU/m3 in residences, and 0.07 and 9.30 EU/m3 in schools and offices. There is strong scientific evidence indicating that age of houses (or housing unit year category), cleaning, farm or rural living, flooring materials (the presence of carpets), number of occupants, the presence of dogs or cats indoors, and relative humidity affect endotoxin loads in settled floor dust. The presence of pets (especially dogs) was extremely strongly associated with endotoxin concentrations in indoor air. However, as reviewed articles show inconsistency, additional studies on these and other possible predicting factors are needed.

  5. Does school physical education really contribute to accelerometer-measured daily physical activity and non sedentary behaviour in high school students? (United States)

    Mayorga-Vega, Daniel; Martínez-Baena, Alejandro; Viciana, Jesús


    Physical education has been highlighted as an important environment for physical activity promotion, however, to our knowledge there are no previous studies examining the contribution of physical education to daily accelerometer-measured physical activity and non sedentary behaviour. The purpose was to compare the accelerometer-measured physical activity and sedentary behaviour between physical education, non-physical education and weekend days in adolescents. Of the 394 students from a Spanish high school that were invited to participate, 158 students (83 boys and 75 girls) aged 13-16 years were analyzed (wear time ≥ 600 min). Participants' physical activity and sedentary behaviour were objectively-measured by GT3X+ accelerometers during physical education (one session), non-physical education and weekend days. Results indicated that overall adolescents had statistically significant greater physical activity levels and lower values of sedentary behaviour on physical education days than on non-physical education and weekend days (e.g., moderate-to-vigorous physical activity = 71, 54 and 57 min; sedentary = 710, 740 and 723 min) (p education contributes significantly to reducing students' daily physical inactivity and sedentary behaviour. Increasing the number of physical education classes seems to be an effective strategy to reduce the high current prevalence of physical inactivity and sedentary behaviour in adolescence.

  7. A pilot study: Horticulture-related activities significantly reduce stress levels and salivary cortisol concentration of maladjusted elementary school children. (United States)

    Lee, Min Jung; Oh, Wook; Jang, Ja Soon; Lee, Ju Young


    The effects of three horticulture-related activities (HRAs), including floral arranging, planting, and flower pressing were compared to see if they influenced changes on a stress scale and on salivary cortisol concentrations (SCC) in maladjusted elementary school children. Twenty maladjusted elementary school children were randomly assigned either to an experimental or control group. The control group carried out individual favorite indoor activities under the supervision of a teacher. Simultaneously, the ten children in the experimental group participated in a HRA program consisting of flower arrangement (FA), planting (P), and flower pressing (PF) activities, in which the other ten children in the control group did not take part. During nine sessions, the activities were completed as follows: FA-FA-FA, P-P-P, and PF-PF-PF; each session lasted 40 min and took place once a week. For the quantitative analysis of salivary cortisol, saliva was collected from the experimental group one week before the HRAs and immediately after the activities for 9 consecutive weeks at the same time each session. In the experimental group, stress scores of interpersonal relationship, school life, personal problems, and home life decreased after the HRAs by 1.3, 1.8, 4.2, and 1.3 points, respectively. In particular, the stress score of school life was significantly reduced (P < 0.01). In addition, from the investigation of the SCCs for the children before and after repeating HRAs three times, it was found that flower arrangement, planting, and flower pressing activities reduced the SCCs by ≥37% compared to the SCCs prior to taking part in the HRAs. These results indicate that HRAs are associated with a reduction in the stress levels of maladjusted elementary school children. Copyright © 2018. Published by Elsevier Ltd.

  8. Stakeholder Perceptions of Barriers and Solutions to Significant Expansion of Postsecondary Enrollment Options for High School Students

    Directory of Open Access Journals (Sweden)

    Carl Wozniak


    Full Text Available Post-secondary experiences for students still in high school have been promoted as a means to increase academic rigor and create a better-trained workforce. Yet little is known regarding supports needed to significantly increase such options. This study obtained input from 411 stakeholders in one Midwestern state, including 201 district superintendents, 181 high school principals, and 23 college dual enrollment officers regarding their use of these options, their perceptions of barriers to program expansion, and their ranking of possible solutions to overcome the barriers. Findings demonstrate that all parties find postsecondary options of value, with traditional dual enrollment the most used option. Although all groups identified funding as a primary barrier, other systemic barriers were of great concern. Participants suggest that expansion of Advanced Placement and early and middle college programs, financial assistance for dually enrolled students, and increased program availability for career and technical options would be beneficial.Wozniak, Carl, (2012.

  12. Unique contributions of dynamic versus global measures of parent-child interaction quality in predicting school adjustment. (United States)

    Bardack, Sarah; Herbers, Janette E; Obradović, Jelena


    This study investigates the unique contribution of microsocial and global measures of parent-child positive coregulation (PCR) in predicting children's behavioral and social adjustment in school. Using a community sample of 102 children, ages 4-6, and their parents, we conducted nested path analytic models to identify the unique effects of 2 measures of PCR on school outcomes. Microsocial PCR independently predicted fewer externalizing and inattention/impulsive behaviors in school. Global PCR did not uniquely relate to children's behavioral and social adjustment outcomes. Household socioeconomic status was related to both microsocial and global measures of PCR, but not directly associated with school outcomes. Findings illustrate the importance of using dynamic measures of PCR based on microsocial coding to further understand how the quality of parent-child interaction is related to children's self-regulatory and social development during school transition.

  13. School children's own views, roles and contribution to choices regarding diet and activity in Spain. (United States)

    Lopez-Dicastillo, O; Grande, G; Callery, P


      Behaviours regarding food and activity are learned during childhood and continue throughout life. Children can be very important agents in making decisions concerning their own well-being and care and their perspective is essential to understanding how they and/or others make choices for them to achieve a healthy lifestyle. However, their perspectives remain under-researched. This study provides an insight into school children's own perspectives, behaviours and contribution to food and activity choices.   The paper reports on the findings from an ethnographic study with 38 Spanish children aged 5-7 years. Information was obtained through participant observations, diaries kept by children and group interviews. Data were analysed using techniques of analytical induction and constant comparison.   The children who took part in this study described choices about activities with enthusiasm. Children saw activity as a way of learning new things, mastering skills and socializing. They were willing to try and experience new activities and games. However, the activities performed depended on parents' agendas and security issues. In contrast, children reported less interest in and active involvement in food choices. They contributed to family food choices indirectly through the expression of their preferences, not wanting to eat what they disliked or tasting new foods.   Children had strong preferences and motivations, particularly about activities which could be harnessed in interventions to prevent obesity and promote healthy diet and activity. Parental involvement and commitment is also important both to encourage exercise according to children's interests and active informed food choices, including introduction to unfamiliar foods. © 2012 Blackwell Publishing Ltd.

  14. Factors that contribute to Hispanic English Language Learners' high academic performance in high school science in the Rio Grande Valley of Texas: A multicase study (United States)

    Elizondo, Antonio

    The purpose of this multicase study was to discover factors that contribute to Hispanic English language learners' (ELL) high academic performance in high school science in the Rio Grande Valley of Texas. Participants were high school seniors enrolled in college-level classes who had scored commended on the science exit-level Texas Assessment of Knowledge and Skills and ranked toward the top of their class. One student from each of four different high schools in south Texas were selected to participate. Schools identified students meeting the participant criteria and provided consent documents. In this qualitative research study, students were interviewed on three different dates. Administrators and science teachers were also interviewed for triangulation. Significant findings showed that intrinsic qualities were mainly responsible for factors contributing to high academic performance. Hispanic ELL students need meaningful responsibilities to internalize self-esteem and self-efficacy to realize high academic performance. Self-motivation, a contributing factor, provides students with a positive outlook on high academic performance and the ability to defer more immediate undermining rewards. Students expect to contribute to society by helping others. This helps their self-esteem as well as their self-worth and supports high academic performance. Parental and teacher support are critical for high academic performance. Low socioeconomic status alone is not a causal factor for poor academic performance. School administrations should assign willing and enthusiastic teachers as mentors to target students and provide skills to parents that promote, inspire, and motivate students' intrinsic qualities. Future studies should examine different leadership styles that maximize teachers' ability to influence students' high academic performance. Finally, students should be given guidance in setting career goals and demonstrating that high academic achievement is attainable and

  15. Factors contributing to the effectiveness of four school-based sexual violence interventions. (United States)

    Clinton-Sherrod, A Monique; Morgan-Lopez, Antonio A; Gibbs, Deborah; Hawkins, Stephanie R; Hart, Laurie; Ball, Barbara; Irvin, Neil; Littler, Nicole


    This study extends past research by examining factors associated with changes in attitudes, knowledge, and intended behaviors related to sexual assault. This study included 1,182 participants from four unique multiple-session school-based sexual violence interventions. Implementation and participant factors examined include single- versus mixed-gender groups, group setting versus classroom lecture setting, and participant gender. Participants completed self-administered, paper-and-pencil pre- and postsurveys. A significant desired overall effect was found on participants' reports of positive attitudes, beliefs, and behavior regarding sexual harassment and personal boundaries and positive dating relationship norms (from pretest to posttest). There were steeper increases over time in both measures, with larger mixed-gender/single-gender differences among boys than among girls. Differences in the impact of participating in mixed- versus single-gender groups depended on classroom versus small group settings. The implications of these findings are discussed for sexual assault prevention programs.

  20. A Model on the Contribution of School Assets to the Achievement of Adolescents' Well-Being and Academic Performance. (United States)

    Pertegal, Miguel-Ángel; Oliva, Alfredo


    The aim of this study was to examine a model on the contribution of school assets on the development of adolescent´s well-being and school success. The sample comprised 1944 adolescents (893 girls and 1051 boys) aged between 12 and 17 years (M = 14.4; SD = 1.13), from secondary schools in Western Andalusia, which completed some self-report questionnaires. The results of structural equation modeling showed the goodness of fit of the initial theoretical model. This model confirmed the importance of school connectedness as a key factor in the relationships between other school assets (social climate; clarity of the rules and values, and positive opportunities and empowerment) and commitment to learning, academic performance and life satisfaction. However, the re-specification of the initial model considered two complementary paths with theoretical sense: first, a direct influence between clarity of the rules and values and commitment to learning, and second, between academic performance and life satisfaction. This model obtained better goodness of fit indices than the first one: χ2 = 16.32; gl = 8; p = .038; χ2/gl = 2.04; SRMR = .018; RSMEA = .023 (95% C.I. = .005; 040); NNFI = .98; CFI = .99. From our study, the need to invest in initiatives focused on the promotion of adolescents' links with their school emerges as a key goal to contribute towards, at the same time, both a good academic performance and a better life satisfaction.

    The economic contribution of medical schools to major urban centres can be substantial, but there is little information on the contribution to the economy of participating communities made by schools that provide education and training away from major cities and academic health science centres. We sought to assess the economic contribution of the Northern Ontario School of Medicine (NOSM) to northern Ontario communities participating in NOSM's distributed medical education programs. We developed a local economic model and used actual expenditures from 2007/08 to assess the economic contribution of NOSM to communities in northern Ontario. We also estimated the economic contribution of medical students or residents participating in different programs in communities away from the university campuses. To explore broader economic effects, we conducted semistructured interviews with leaders in education, health care and politics in northern Ontario. The total economic contribution to northern Ontario was $67.1 million based on $36.3 million in spending by NOSM and $1.0 million spent by students. Economic contributions were greatest in the university campus cities of Thunder Bay ($26.7 million) and Sudbury ($30.4 million), and $0.8-$1.2 million accrued to the next 3 largest population centres. Communities might realize an economic contribution of $7300-$103 900 per pair of medical learners per placement. Several of the 59 interviewees remarked that the dollar amount could be small to moderate but had broader economic implications. Distributed medical education at the NOSM resulted in a substantial economic contribution to participating communities.

  8. [Nutritional contribution of snacks to food patterns in school children who are overweight or obese compared to school children who are of normal weight in Cartago, Costa Rica]. (United States)

    Ibarra López, Marianela; Llobet León, Laia; Fernández Rojas, Xinia


    In order to assess the nutritional contribution of snacks to food patterns in school children, a sample of 80 Costa Rican elementary schoolchildren: 40 children who were overweight or obese (the case group) and 40 children with normal weight (the control group) were evaluated. The anthropometric evaluation included weight, height, and triceps skinfold thickness. Food patterns were determined using a 3-day food diary. Snacks consumed throughout the day were classified and analyzed according to their place of preparation and location of consumption and to the time of the day in which they were consumed. The results of this study revealed that "afternoon snacks" and "snacks prepared and eaten at home" were the most frequently consumed snacks by both case and control groups. The girls in the case group had a significantly larger intake of energy and carbohydrates in their "afternoon snacks" and the "snacks prepared and eaten at home" as compared to girls in the control group. Boys in the case group showed a significantly greater consumption of saturated fat in the "snacks prepared and eaten at home" as compared to boys in the control group. It was concluded that the intake of "afternoon snacks" and of those "prepared and eaten at home" could be related with the incidence of overweight/obesity in the sample of study and therefore nutrition education aimed at parents and children is crucial and could play an important role in its prevention.

  16. The young and the policy: contributions of school of social sciences for socialization policy

    Directory of Open Access Journals (Sweden)

    Thiago Ingrassia Pereira


    Full Text Available The challenges that the youth faces in a globalized world are enormous, and they expose it to achievements and stresses that are materialized during the scholar period, especially in High School, which is an era of transitions to the adult life and to the active citizenship. Therefore, politics should be rather than taught, lived and studied in school, due to the possibilities improved by the mandatory presence of Social Sciences in the curriculum of high school, and discuss the space of the student movement today to understand the political mediations that are in play. Objectively, this paper focuses on the set of beliefs, norms and values that promote political socialization of high school students from a private school located in Porto Alegre. Through a self-administrated questionnaire, it was possible to observe a scenario that ranges from apathy to disbelief, while the involvement in alternative spaces is increasing, such as volunteering and NGOs.

  18. Measuring the impact of a burns school reintegration programme on the time taken to return to school: A multi-disciplinary team intervention for children returning to school after a significant burn injury. (United States)

    Returning to school can be a major step for burn-injured children, their family, and staff and pupils at the receiving school. Previous literature has recognised the difficulties children may face after a significant injury and factors that may influence a successful reintegration. A regional paediatric burns service recognised that some patients were experiencing difficulties in returning to school. A baseline audit confirmed this and suggested factors that hindered or facilitated this process, initiating the development of a school reintegration programme (SRP). Since the programme's development in 2009, it has been audited annually. The aim of this paper was to evaluate the impact of the SRP by presenting data from the 2009 to 2011 audits. For the baseline audit, the burn care team gathered information from clinical records (age, gender, total body surface area burned (TBSA), skin grafting and length of stay) and telephone interviews with parents and teachers of the school returners. For the re-audits, the same information was gathered from clinical records and feedback questionnaires. Since its introduction, the mean length of time from discharge to return to school has dropped annually for those that opted into the programme, when compared to the baseline by 62.3% (53 days to 20 days). Thematic analysis highlights positive responses to the programme from all involved. Increased awareness and feeling supported were amongst the main themes to emerge. Returning to school after a significant burn injury can be challenging for all involved, but we hypothesise that outreach interventions in schools by burns services can have a positive impact on the time it takes children to successfully reintegrate.

To overcome this limitation, this study defined and computed a relative count of publications called ‘CP’ (credit-based contribution points, based on the sequence-determines-credit (SDC method, which takes into account the level of contribution of each author. Analyses were done on a sample of 410 Vietnamese social scientists whose publications were indexed in the Scopus database during 2008–2017. The results showed that the average CP of Vietnamese researchers in the field of social sciences and humanities is very low: more than 88% of authors have a CP less than five over a span 10 years. Researchers with a higher CP were mostly 40–50 years old; however, even for this sub-group, the mean CP was only 3.07. Multiple attributes of first-authorship—including knowledge, research skills, and critical thinking—could boost the CP by a ratio of 1:1.06. There is no evidence of gender differences in productivity, however, there is a regional difference. These findings offer significant insights into the education system in regard to science and technology, namely policy implications for science funding and management strategies for research funds.

    Medium and large size isolated systems with a significant contribution from renewable energy sources, specifically eolic energy, are not conveniently operated at the present, neither by the conventional ways of unit commitment/load dispatcher nor by the simplified procedures used in the small isolated power networks. This paper presents a new approaching, in the CARE framework which is financially supported by the European Union through the EEN-JOULE assistance program. The principal idea is to perform unit commitment on-line in the same dispatching cycle, by using the load forecasting and the more recent wind power. The process includes dynamic safety fast evaluation and a module for helping the decision making.

    Full Text Available This work presents an intervention research and participant that analyzes how the production of digital videos by students of a municipal school brings contributions to the construction of the knowledge contextualized in the teaching of sciences. For this purpose, references were used to cover four thematic areas: the use of digital technologies in the school context; The contextualization of contents in science education; Communication and mediation in school; And finally the production of digital video in science education. The qualitative methodology used, using semi-structured interviews and participant observation. Previously, the beginnings of the work of the students, workshops were created to create digital video, then a semistructured interview was carried out, in the post-production phase, with the students and the teacher. The results show that the production of digital videos have brought significant contributions to the students since participating in the workshop of video production, to the stage of conclusion and presentation of digital video in the classroom. With this, the students used the production of digital video as a differentiated methodology, source of research and production of knowledge. Participants, directors, learners and authors in the elaboration of the video, searching information related to the content, performing readings, planning the production, the "script", accompanying the assembly, using digital technologies in production, disseminating and participating in debates collectively. They constructed the knowledge proposed in science teaching and brought the curricular content studied into practice, reinforcing the discussion about the use and production of digital video as an educational tool.

    Full Text Available The use of technology in schools made its mark at the end of the XX century and mainly expands in the XXI century. With the advance of globalization, technology has become indispensable presence in daily life and at this juncture has been adding new forms of social mediation, revolutionizing the communicability, bringing in evidence different ways of communication and interaction among people. This work discusses about the importance of Information and Communication Technologies (ICT in the educational context, considering the public policies, responsible for their integration in schools, as well as the vision that educators have about them and obstacles they face in the practical use of ICT. The literature review about the theme gave support to data constructed from interviews with three teachers of state schools in Itaperuna. The interviews were based on the issue of how teachers have seen the advent of Information and Communication Technology in the school environment and what they have done to incorporate it for the benefit of education. Through interviews and literature review it was found that with the help of the ICT, the school can teach what it means to live immersed in a shared knowledge community. The school can also educate for citizenship exercise, qualification for work and social practices, as described in the LDB. However, despite the contributions in social spects and learning enabled to the students, we also observed substantial obstacles that clutter the scope of success in the use of ICT in school. The deficit teacher training and infrastructural aspects of the institutions are some of the obstacles.

  4. Negotiating a new day: parents' contributions to supporting students' school functioning after exposure to trauma

This study explores parents' experiences of supporting adolescents in regaining school functioning after the July 2011 massacre at Utøya summer camp in Norway. One year after the attack, 87 parents of 63 young people who survived the massacre were interviewed using qualitative interviews. The qualitative data were analyzed using thematic analysis. All parents were actively supportive of their children, and described a demanding process of establishing new routines to make school attendance possible. Most parents described radical changes in their adolescents. The struggle of establishing routines often brought conflict and frustration into the parent–adolescent relationship. Parents were given general advice, but reported being left alone to translate this into action. The first school year after the trauma was described as a frustrating and lonely struggle: their adolescents were largely unable to restore normal daily life and school functioning. In 20% of the cases, school–home relationships were strained and were reported as a burden because of poor understanding of needs and insufficient educational adaptive measures; a further 20% reported conflict in school–home relationships, while 50% were either positive or neutral. The last 10%, enrolled in apprenticeship, dropped out, or started working, instead of finishing school. Implications for supporting parents with traumatized adolescent students are indicated.

  5. Catabolism of Branched Chain Amino Acids Contributes Significantly to Synthesis of Odd-Chain and Even-Chain Fatty Acids in 3T3-L1 Adipocytes.

    Directory of Open Access Journals (Sweden)

    Scott B Crown

    Full Text Available The branched chain amino acids (BCAA valine, leucine and isoleucine have been implicated in a number of diseases including obesity, insulin resistance, and type 2 diabetes mellitus, although the mechanisms are still poorly understood. Adipose tissue plays an important role in BCAA homeostasis by actively metabolizing circulating BCAA. In this work, we have investigated the link between BCAA catabolism and fatty acid synthesis in 3T3-L1 adipocytes using parallel 13C-labeling experiments, mass spectrometry and model-based isotopomer data analysis. Specifically, we performed parallel labeling experiments with four fully 13C-labeled tracers, [U-13C]valine, [U-13C]leucine, [U-13C]isoleucine and [U-13C]glutamine. We measured mass isotopomer distributions of fatty acids and intracellular metabolites by GC-MS and analyzed the data using the isotopomer spectral analysis (ISA framework. We demonstrate that 3T3-L1 adipocytes accumulate significant amounts of even chain length (C14:0, C16:0 and C18:0 and odd chain length (C15:0 and C17:0 fatty acids under standard cell culture conditions. Using a novel GC-MS method, we demonstrate that propionyl-CoA acts as the primer on fatty acid synthase for the production of odd chain fatty acids. BCAA contributed significantly to the production of all fatty acids. Leucine and isoleucine contributed at least 25% to lipogenic acetyl-CoA pool, and valine and isoleucine contributed 100% to lipogenic propionyl-CoA pool. Our results further suggest that low activity of methylmalonyl-CoA mutase and mass action kinetics of propionyl-CoA on fatty acid synthase result in high rates of odd chain fatty acid synthesis in 3T3-L1 cells. Overall, this work provides important new insights into the connection between BCAA catabolism and fatty acid synthesis in adipocytes and underscores the high capacity of adipocytes for metabolizing BCAA.

    Full Text Available This work reports the experience of training school managers based on the theoretical assumptions of historical-cultural psychology. The intervention took place as one of the actions of the Project Education Without Borders (PESF - a partnership between the Municipal Secretary of Education and the psychology department of a state University of São Paulo in assisting schools that have low IDEB (Basic Education Development Index. Study meetings were held monthly with the managers of the six participating schools and with representatives of the pedagogical department of the Municipal Secretary of Education. The themes of the meetings were established based on the demand of the group, which chose as study goals: 1. understanding the production of motives and interests for the students' learning and 2. understanding how the study activity is formed and developed as a main activity at school age. As a strategy of theoretical-practical articulation, the proposition of study tasks on the themes discussed in each meeting was adopted. As a reference, the concept of study task of Davydov and Markova (1987 was used. The results point out that the application of the theoretical assumptions of historical-cultural psychology to the concrete demands of the organization of teaching in the daily school life makes it possible to overcome the traditional dichotomy between theory and practice in teacher education and promotes the construction of new guidelines for pedagogical practice.

  10. Neuraminidase-1 contributes significantly to the degradation of neuronal B-series gangliosides but not to the bypass of the catabolic block in Tay–Sachs mouse models

    Directory of Open Access Journals (Sweden)

    Z.K. Timur


    Full Text Available Tay–Sachs disease is a severe lysosomal storage disorder caused by mutations in the HEXA gene coding for α subunit of lysosomal β-Hexosaminidase A enzyme, which converts GM2 to GM3 ganglioside. HexA−/− mice, depleted of the β-Hexosaminidase A iso-enzyme, remain asymptomatic up to 1 year of age because of a metabolic bypass by neuraminidase(s. These enzymes remove a sialic acid residue converting GM2 to GA2, which is further degraded by the still intact β-Hexosaminidase B iso-enzyme into lactosylceramide. A previously identified ganglioside metabolizing neuraminidase, Neu4, is abundantly expressed in the mouse brain and has activity against gangliosides like GM2 in vitro. Neu4−/− mice showed increased GD1a and decreased GM1 ganglioside in the brain suggesting the importance of the Neu4 in ganglioside catabolism. Mice with targeted disruption of both HexA and Neu4 genes showed accumulating GM2 ganglioside and epileptic seizures with 40% penetrance, indicating that the neuraminidase Neu4 is a modulatory gene, but may not be the only neuraminidase contributing to the metabolic bypass in HexA−/− mice. Therefore, we elucidated the biological role of neuraminidase-1 in ganglioside degradation in mouse. Analysis of HexA−/−Neu1−/− and HexA−/−Neu4−/−Neu1−/− mice models showed significant contribution of neuraminidase-1 on B-series ganglioside degradation in the brain. Therefore, we speculate that other neuraminidase/neuraminidases such as Neu2 and/or Neu3 might be also involved in the ganglioside degradation pathway in HexA−/− mice.

    Annalisa Marzocca


    Full Text Available Children spend a large amount of time in school environments and when Indoor Air Quality (IAQ is poor, comfort, productivity and learning performances may be affected. The aim of the present study is to characterize IAQ in a primary school located in Taranto city (south of Italy. Because of the proximity of a large industrial complex to the urban settlement, this district is one of the areas identified as being at high environmental risk in Italy. The study carried out simultaneous monitoring of indoor and outdoor Volatile Organic Compounds (VOC concentrations and assessed different pollutants’ contributions on the IAQ of the investigated site. A screening study of VOC and determination of Benzene, Toluene, Ethylbenzene, Xylenes (BTEX, sampled with Radiello® diffusive samplers suitable for thermal desorption, were carried out in three classrooms, in the corridor and in the yard of the school building. Simultaneously, Total VOC (TVOC concentration was measured by means of real-time monitoring, in order to study the activation of sources during the monitored days. The analysis results showed a prevalent indoor contribution for all VOC except for BTEX which presented similar concentrations in indoor and outdoor air. Among the determined VOC, Terpenes and 2-butohxyethanol were shown to be an indoor source, the latter being the indoor pollutant with the highest concentration.

    Marković Vujica


    Full Text Available Background/Aim. A term 'ocular hypertension' is used when IOP is found to be > 21 mmHg on two consecutive occasions, in the absence of detectable glaucomatous damage. The aim of this study was to determine the significance and contribution of Heidelberg Retinal Tomography II (HRT II results that show very early, subtle changes in retinal neurofibre layers (RNFL in the optic nerve head that are specific for glaucoma itself (the loss of neuroretinal rim area and an increase of Cup/Disc ratio, but are not possible to register by an ophthalmoscope. Also, when the results of the functional tests remain unchanged, that confirms the conversion of ocular hypertension into glaucoma. Methods. During a 5-year study period (2002-2007, 29 patients with ocular hypertension were examined. The frequency of control examinations, based on the presence of risk factors for glaucoma development, was 3-6 months. The examination also included IOP measurements with Goldmann Applanation Tonometry (GAT, central corneal thickness (CCT determination by pachymetry, the examination of chamber angle using indirect gonioscopy, visual field tests by computerized perimetry and also papillae nervi optici (PNO examination by using HRT II. The application of HRT II enables a great number of stereometric parameters of optic disc, the most important being the rim area and Cup/Disc (C/D ratio, which was followed during the control examination by each segment, as well as PNO in global. Results. In the examination period, three cases of conversion of ocular hypertension into a primary open-angle glaucoma were found. In the group of patients with ocular hypertension, HRT II results after six months did not show a significant increase in C/D ratio. No significant loss of rim area or rim volume was found either. In three cases of conversion, HRT II results after 3 months showed an increase of C/D ratio and also a significant loss in rim volume at first examination (0.413 comparing to the

    Haerens, L.; Deforche, B.; Cardon, G.; Bourdeaudhuij, I.D.; Craeynest, M.; Maes, L.


    The present study aimed at investigating the influence of home, neighbourhood and school environmental factors on adolescents' engagement in self-reported extracurricular physical activity and leisure time sports and on MVPA objectively measured by accelerometers. Environmental factors were assessed using questionnaires. Gender specific hierarchical regression analyses were conducted, with demographic variables entered in the first block, and environmental, psychosocial factors and interactions terms entered in the second block. Participation in extracurricular activities at school was positively related to the number of organized activities and the provision of supervision. Perceived accessibility of neighborhood facilities was not related to engagement in leisure time sports, whereas the availability of sedentary and physical activity equipment was. Findings were generally supportive of ecological theories stating that behaviors are influenced by personal and environmental factors that are constantly interacting.

  9. Preventing violence against children in schools: Contributions from the Be Safe program in Sri Lanka. (United States)

    Lam, Steven; Zwart, Christine; Chahal, Inem; Lane, David; Cummings, Harry


    Violence against children is a global public health issue with serious social, economic, physical, and emotional impacts. This study evaluates the effectiveness of a school-based program aimed to prevent and respond to physical, sexual, and psychological violence against children in Sri Lanka from the perspective of parents. A cross-sectional retrospective study design was used. A total of 835 parents of children who participated in the program were surveyed across seven districts in Sri Lanka. Dose-response analyses were conducted to assess for correlations between program exposure and perceived prevention of violence against children. Low to moderate correlations were found between exposure to the program and perceived child safety in schools, school policies, and in the community. The findings provide preliminary evidence of program effectiveness; however, more efforts are needed to validate and sustain outcomes. Implications for future violence prevention programming, along with the use of dose-response evaluations, are discussed. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Raupach, Tobias; Spering, Christopher; Bäumler, Christine; Burckhardt, Gerhard; Trümper, Lorenz; Pukrop, Tobias


    In addition to patient care and research activity, physicians working in medical school hospitals serve as teachers in undergraduate medical education. However, teaching qualifications of German university hospital physicians have not been studied in great detail. In January 2009, medical students as well as physicians involved in medical teaching at Göttingen Medical School, Germany, were invited to complete an online survey addressing their views on clinical teachers' educational skills. In addition, physicians' motivation to engage in pedagogical training was assessed. During a 12-day period, 359 students and 126 physicians involved in undergraduate medical education completed the survey. The latter did not feel well prepared for their teaching activities. At the same time, they expressed the willingness to improve their teaching skills. Students felt that, across all instructional methods, teachers would benefit from teacher training programs. In order to improve undergraduate education for future physicians, politicians and local representatives alike must set the scene for the implementation of faculty development measures in German medical schools.

  11. Sediment contribution from coastal-cliff erosion into the Nile's littoral cell and its significance to cliff-retreat mitigation efforts (United States)

    Katz, Oded; Mushkin, Amit; Crouvi, Onn; Alter, Samuel; Shemesh, Ran


    In 2013 the government of Israel initiated a national mitigation program aimed to prevent further collapse and retreat of the country's coastal cliffs, which occur along the northern termination of the Niles's littoral cell (NLC) in the eastern Mediterranean. The goals of this large-scale program are to protect infrastructure and property proximal to the cliff and to conduct long-term maintenance and monitoring of this highly dynamic and sensitive land-sea interface that spans 40 km of Israel's coast line. Here, we examine the possible impact of proposed cliff retreat mitigation efforts on long-shore sediment transport (LST) and coastal dynamics in the region. We used airborne LiDAR spanning a 9-year period between 2006 and 2015 to quantify the annual contribution of sediment eroded from a 20-km-long segment of Israel's coastal cliffs into the NLC. Our measurements reveal 282±85*103 m3 of sediment eroded from the cliff and delivered into the NLC during the studied period. Considering our study area comprises 50% of Israel's sea cliffs we infer an average contribution rate of 30,000-60,000 m^3/yr of cliff-derived sediment into the NLC prior to the planned broad-scale implementation of cliff-retreat mitigation measures. Previous studies report an average net LST flux of 80,000 - 90,000 m3 that reaches the northern termination of the NLC at Haifa Bay annually. Thus, our results suggest that Israel's actively eroding coastal cliffs are primary contributors (40-80%) to the LST budget along the northern termination of the NLC. It therefore appears that successful implementation of the coastal-cliff protection program along Israel's coastline will result in a significant sand deficit, which may drive LST in this part of the NLC out of its 'background' state. In the likely case that the energy/currents driving LST do not change, a possible outcome of this sediment deficit could be increased beach erosion along Israel's coast line to make up for the lost volumes of cliff

  12. Education within public management in South Africa: A focus on external Whole-School Evaluation process’ contribution in Mpumalanga province

    Directory of Open Access Journals (Sweden)

    Richard Siphamandla Ryan Mathaba


    Full Text Available The study focused on the role played by public sector management in South Africa towards the country’s total development and improvement. This article also analyses how through the Whole School Evaluation (WSE process, the education system in South Africa seeks to ensure that the schooling is effective. This paper examines public management, public administration as well as new public management (NPM. The aim is to illustrate a view of how education fits in the broader public management and how the WSE process assists schooling in South Africa and Mpumalanga in particular. This is to ensure that the schooling is effective and contribute towards service delivery and the country’s overall development and improvement. Furthermore, WSE as a process, is viewed through five of NPM undisputable and debatable characteristics of accountability for performance; performance measurement; performance auditing; policy analysis and evaluation; and strategic planning and management. Public management functions and public management principles are discussed from a point of how the WSE process strives to ensure that it complies with these function and principles, and how this compliance benefit school improvement. This paper came to a number of conclusions regarding education within public management from a WSE perspective. Firstly, education through the external WSE process conforms to this principle of New Public Management in that evaluation is aimed at improving the quality of education. Also, the external WSE, as a process, and education in general, through the NPM principles can be performed within public management. Furthermore, external WSE conforms to public management principles as well as Batho Pele principles.

  16. The school curriculum for ethnic minority pupils: A contribution to a debate (United States)

    Saunders, Malcolm


    This paper discusses some of the canicular needs of children of migrant parents in the United Kingdom (in particular those of South Asian and West Indian origins), against the background of current provision. The author argues the merits of a "cultural accommodation" strategy and outlines the "human rights" model of education which that strategy implies. He then analyses three major problem areas faced by children of migrant workers: conflicts of identity, communication difficulties, and unequal access to employment opportunities. In a final section, tentative but practical suggestions are given of how the school curriculum can address these problems.

  1. German and Japanese Education in the Shadow – Do Out-of-School Lessons really contribute to Class Reproduction?

    Directory of Open Access Journals (Sweden)

    Steve R. Entrich


    Full Text Available Considering the great impact the first PISA-results caused in Germany and Japan, this study seeks to provide an explanation for the continuous higher achievement rates of students in the PISA-winner country Japan compared to their German peers. Another great difference between the two participants that was detected in PISA is the correlation between students’ social origin and educational achievement, which is still very strong in Germany but not in Japan. The author assumes the reason for these differences lay outside the formal school system, in the sector of shadow education. The so called juku-industry in Japan provides out-of-school lessons that seem to enable all Japanese students to achieve top results regardless of their social origin. In Germany the increased use of Nachhilfe is seen as an indicator for the downfall of the compulsory school system and a problem that seem to widen the gap in education levels all the more. If in Japan almost every household regardless of its social status sends its children to out-of-school classes, the assumption that people do invest in further education in terms of extra classes at juku believing this will have a neutralizing effect on disadvantaged family background suggests itself. Consequently the author intends to refute the prevailing assumption of researchers in Germany and Japan stating that out-ofschool lessons just contribute to the reproduction of class structure. Using secondary data as well as PISA-data the author wants to show that shadow education helps to counteract educational disadvantages through the provision of various educational opportunities.

  7. Significance of out-of-plane electronic contributions in Bi-cuprates studied by resonant photoelectron spectroscopy at the Cu2p edge (United States)

    Janowitz, Christoph; Schmeißer, Dieter


    In high-temperature superconductors with a layered crystal structure, the copper-oxygen planes are commonly considered to dominate the electronic properties around the Fermi energy. As a consequence, out-of-plane contributions are often neglected in the description of these materials. Here we report on a resonant photoemission study of Pb0,4Bi1,6Sr2,0CaCu2O8 ((Pb, Bi)-2212) and Pb0,6Bi1,4Sr1.5La0.5CuO6 ((Pb, Bi)-2201)) single crystals to unravel the resonant decay mechanisms at the Cu2p absorption edge. We find evidence for a pronounced polarization dependence caused by two different Auger processes for in-plane and out-of-plane orientations. We deduce that the lowest energy valence state—which is involved in the two Auger processes—consists of three-dimensional contributions by admixed out-of-plane Sr, Bi, and O2p states. It also suggests that the doping-induced charge density is dynamic, fluctuating within the Cu-O plane, and spills out perpendicular to it. This suggests that out-of-plane electronic degrees of freedom should be included in future consistent theoretical models of these materials.

  8. Significant contribution of the 3′→5′ exonuclease activity to the high fidelity of nucleotide incorporation catalyzed by human DNA polymerase ϵ (United States)

    Zahurancik, Walter J.; Klein, Seth J.; Suo, Zucai


    Most eukaryotic DNA replication is performed by A- and B-family DNA polymerases which possess a faithful polymerase activity that preferentially incorporates correct over incorrect nucleotides. Additionally, many replicative polymerases have an efficient 3′→5′ exonuclease activity that excises misincorporated nucleotides. Together, these activities contribute to overall low polymerase error frequency (one error per 106–108 incorporations) and support faithful eukaryotic genome replication. Eukaryotic DNA polymerase ϵ (Polϵ) is one of three main replicative DNA polymerases for nuclear genomic replication and is responsible for leading strand synthesis. Here, we employed pre-steady-state kinetic methods and determined the overall fidelity of human Polϵ (hPolϵ) by measuring the individual contributions of its polymerase and 3′→5′ exonuclease activities. The polymerase activity of hPolϵ has a high base substitution fidelity (10−4–10−7) resulting from large decreases in both nucleotide incorporation rate constants and ground-state binding affinities for incorrect relative to correct nucleotides. The 3′→5′ exonuclease activity of hPolϵ further enhances polymerization fidelity by an unprecedented 3.5 × 102 to 1.2 × 104-fold. The resulting overall fidelity of hPolϵ (10−6–10−11) justifies hPolϵ to be a primary enzyme to replicate human nuclear genome (0.1–1.0 error per round). Consistently, somatic mutations in hPolϵ, which decrease its exonuclease activity, are connected with mutator phenotypes and cancer formation. PMID:25414327

  11. Delineation and Analysis of Uncertainty of Contributing Areas to Wells at the Southbury Training School, Southbury, Connecticut (United States)

    Starn, J. Jeffrey; Stone, Janet Radway; Mullaney, John R.


    Contributing areas to public-supply wells at the Southbury Training School in Southbury, Connecticut, were mapped by simulating ground-water flow in stratified glacial deposits in the lower Transylvania Brook watershed. The simulation used nonlinear regression methods and informational statistics to estimate parameters of a ground-water flow model using drawdown data from an aquifer test. The goodness of fit of the model and the uncertainty associated with model predictions were statistically measured. A watershed-scale model, depicting large-scale ground-water flow in the Transylvania Brook watershed, was used to estimate the distribution of groundwater recharge. Estimates of recharge from 10 small basins in the watershed differed on the basis of the drainage characteristics of each basin. Small basins having well-defined stream channels contributed less ground-water recharge than basins having no defined channels because potential ground-water recharge was carried away in the stream channel. Estimates of ground-water recharge were used in an aquifer-scale parameter-estimation model. Seven variations of the ground-water-flow system were posed, each representing the ground-water-flow system in slightly different but realistic ways. The model that most closely reproduced measured hydraulic heads and flows with realistic parameter values was selected as the most representative of the ground-water-flow system and was used to delineate boundaries of the contributing areas. The model fit revealed no systematic model error, which indicates that the model is likely to represent the major characteristics of the actual system. Parameter values estimated during the simulation are as follows: horizontal hydraulic conductivity of coarse-grained deposits, 154 feet per day; vertical hydraulic conductivity of coarse-grained deposits, 0.83 feet per day; horizontal hydraulic conductivity of fine-grained deposits, 29 feet per day; specific yield, 0.007; specific storage, 1.6E-05

  12. U.S. contribution of section A.3. The significance of long-term supply and energy sufficiency prospects offered by fast breeders

    International Nuclear Information System (INIS)


    Costs involved in breeder deployment are identified and analyzed, i.e., high breeder capital costs, fuel cycle costs, research and development costs and discount rates. It is pointed out that while there are potential benefits to be derived from future application of fast breeders, there are also significant costs and other factors requiring consideration. Careful country-specific analyses are needed. Such analyses may conclude for example that although breeders could become economical in less highly industrialized nations, such nations may find it more economical and practical to purchase reprocessing services from existing large commercial size plants rather than deploy their own small scale reprocessing plants

  13. Partner meeting place is significantly associated with gonorrhea and chlamydia in adolescents participating in a large high school sexually transmitted disease screening program. (United States)

    Lewis, Felicia M T; Newman, Daniel R; Anschuetz, Greta L; Mettey, Aaron; Asbel, Lenore; Salmon, Melinda E


    From 2003 to 2012, the Philadelphia High School STD Screening Program screened 126,053 students, identifying 8089 Chlamydia trachomatis (CT)/Neisseria gonorrhoeae (GC) infections. We examined sociodemographic and behavioral factors associated with CT/GC diagnoses among a sample of this high-risk population. Standardized interviews were given to infected students receiving in-school CT/GC treatment (2009-2012) and to uninfected students calling for results (2011-2012). Sex-stratified multivariable logistic models were created to examine factors independently associated with a CT/GC diagnosis. A simple risk index was developed using variables significant on multivariable analysis. A total of 1489 positive and 318 negative students were interviewed. Independent factors associated with a GC/CT diagnosis among females were black race (adjusted odds ratio [AOR], 2.27; confidence interval, 1.12-4.58), history of arrest (AOR, 2.26; 1.22-4.21), higher partner number (AOR, 1.75; 1.05-2.91), meeting partners in own neighborhood (AOR, 1.92; 1.29-2.86), and meeting partners in venues other than own school, neighborhood, or through friends ("all other"; AOR, 9.44; 3.70-24.09). For males, factors included early sexual debut (AOR, 1.99; 1.21-3.26) and meeting partners at "all other" venues (AOR, 2.76; 1.2-6.4); meeting through friends was protective (AOR, 0.63; 0.41-0.96). Meeting partners at own school was protective for both sexes (males: AOR, 0.33; 0.20-0.55; females: AOR, 0.65; 0.44-0.96). Although factors associated with a GC/CT infection differed between males and females in our sample, partner meeting place was associated with infection for both sexes. School-based screening programs could use this information to target high-risk students for effective interventions.

  14. Contribution of the ELFG test in algorithms of non-invasive markers towards the diagnosis of significant fibrosis in chronic hepatitis C.

    Directory of Open Access Journals (Sweden)

    Jean-Pierre Zarski

    Full Text Available BACKGROUND AND AIMS: We aimed to determine the best algorithms for the diagnosis of significant fibrosis in chronic hepatitis C (CHC patients using all available parameters and tests. PATIENTS AND METHODS: We used the database from our study of 507 patients with histologically proven CHC in which fibrosis was evaluated by liver biopsy (Metavir and tests: Fibrometer®, Fibrotest®, Hepascore®, Apri, ELFG, MP3, Forn's, hyaluronic acid, tissue inhibitor of metalloproteinase-1 (TIMP1, MMP1, collagen IV and when possible Fibroscan™. For the first test we used 90% negative predictive value to exclude patients with F≤1, next an induction algorithm was applied giving the best tests with at least 80% positive predictive value for the diagnosis of F≥2. The algorithms were computed using the R Software C4.5 program to select the best tests and cut-offs. The algorithm was automatically induced without premises on the part of the investigators. We also examined the inter-observer variations after independent review of liver biopsies by two pathologists. A medico-economic analysis compared the screening strategies with liver biopsy. RESULTS: In "intention to diagnose" the best algorithms for F≥2 were Fibrometer ®, Fibrotest®, or Hepascore® in first intention with the ELFG score in second intention for indeterminate cases. The percentage of avoided biopsies varied between 50% (Fibrotest® or Fibrometer®+ELFG and 51% (Hepascore®+ELFG. In "per-analysis" Fibroscan™+ELFG avoided liver biopsy in 55% of cases. The diagnostic performance of these screening strategies was statistically superior to the usual combinations (Fibrometer® or Fibrotest®+Fibroscan™ and was cost effective. We note that the consensual review of liver biopsies between the two pathologists was mainly in favor of F1 (64-69%. CONCLUSION: The ELFG test could replace Fibroscan in most currently used algorithms for the diagnosis of significant fibrosis including for those patients

  15. Anhaia Mello's contributions to urbanism of the city of São Paulo: from Ebenezer Howard to the Chicago School

    Directory of Open Access Journals (Sweden)

    Rodrigo Alberto Toledo


    Full Text Available This article draws an analytical panel of the main contributions and interpretations of Anhaia Mello about the problem of growing cities from the perspective of urbanism in the city of São Paulo. Based on a broad review of the literature, this article describes how urban planning migrated to academia and simultaneously to city ordinances, which resulted in the regulatory framework of land use and occupancy that ultimately produced “The Regional São Paulo Plan.” Research in the FAU-USP library revealed family documents and collections that helped reconstruct the intellectual history and career of urban planner and professor Anhaia Mello. The author of this paper organized the data gathered from these collections and compared them to the literature to reconstruct Anhaia Mello’s thoughts on how the city of São Paulo should grow in the mid-20th century. The analyses produced by Anhaia Mello served as a guide to identify the crystallization of a planning proposal for the city, which believed in reversing the metropolitan cycle and containing urban growth by applying the garden-city concept defended by Le Corbusier and the Chicago school.

  16. A comparison of fathers' and mothers' contributions in the prediction of academic performance of school-age children in Hong Kong. (United States)

    Tam, Vicky C W


    Asystematic study of the linkages between gender issues and parenting is made among Chinese families. This study examines sex differences in parenting attributes across fathers and mothers and towards sons and daughters, and compares the contributions of fathers and mothers to the prediction of academic performance across boys and girls. Four parenting attributes are included: nurturance, psychological control, parental involvement in education, and parental academic efficacy. Data were collected from 461 Chinese father-mother-child triads of children studying Grade 3 to 5 in Hong Kong. Findings of this study, based on multivariate analysis of variance, showed that parental roles followed traditional Chinese cultural expectations. Compared to the fathers, Chinese mothers of school-age children in Hong Kong were more loving and caring, more involved in children's education, and more efficacious in promoting children's academic performance. Results of hierarchical regression analysis examining the role of child's sex as a moderator showed cross-sex influence in parental contribution to academic performance with respect to parental psychological control and academic efficacy. Specifically, boys benefited more from maternal efficacy than girls did and they were also more hampered by mothers with high psychological control, while girls' academic performance was more enhanced by paternal academic efficacy than boys. A gender-balance approach that highlights the significance of gender in moderating parental contributions to academic performance was thus supported. Future research should continue to focus on psychological control and domain-specific parental attributes as potential sources of gender-linked parent-child associations. Investigations should also explore other cognitive and noncognitive domains of child outcome, different child age groups, as well as Chinese populations in various geographical regions.

  6. `I Actually Contributed to Their Research': The influence of an abbreviated summer apprenticeship program in science and engineering for diverse high-school learners (United States)

    Burgin, Stephen R.; McConnell, William J.; Flowers, Alonzo M., III


    This study describes an investigation of a research apprenticeship program that we developed for diverse high-school students often underrepresented in similar programs and in science, technology, engineering, and math (STEM) professions. Through the apprenticeship program, students spent 2 weeks in the summer engaged in biofuels-related research practices within working university chemistry and engineering laboratories. The experience was supplemented by discussions and activities intended to impact nature of science (NOS) and inquiry understandings and to allow for an exploration of STEM careers and issues of self-identity. Participants completed a NOS questionnaire before and after the experience, were interviewed multiple times, and were observed while working in the laboratories. Findings revealed that as a result of the program, participants (1) demonstrated positive changes in their understandings of certain NOS aspects many of which were informed by their laboratory experiences, (2) had an opportunity to explore and strengthen STEM-related future plans, and (3) examined their self-identities. A majority of participants also described a sense of belonging within the laboratory groups and believed that they were making significant contributions to the ongoing work of those laboratories even though their involvement was necessarily limited due to the short duration of the program. For students who were most influenced by the program, the belonging they felt was likely related to issues of identity and career aspirations.

  11. Contribution of free play towards physical activity guidelines for New Zealand primary school children aged 7-9 years. (United States)

    McGall, S E; McGuigan, M R; Nottle, C


    the objectives of this study were to investigate children's physical activity patterns to gain comparisons between home and school and to determine whether the current physical activity guidelines of 60 min of moderate to vigorous physical activity (MVPA) daily were being met. participants were recruited from two New Zealand primary schools (60 children, mean age (SD) 8.3 (0.7) years). Physical activity was measured for seven consecutive days using Actigraph accelerometers. Total activity and average counts were determined for school playtime, after school and weekends. Differences between average counts for these intervals were compared using the t statistic. Time and percentage of time spent were categorised into the activity thresholds: sedentary (5200). Total activity for each day was also determined. no child met the recommended 60 min of MVPA daily during the investigation. Compared to school playtime, activity counts were lower by 36% (CI 25% to 45.5%, p<0.001, effect size (ES)=-1.29) after school, 50.1% (CI 37% to 60.5%, p<0.001, ES=-2.01) on Saturday and 57.4% (CI 46.3% to 66.3%, p<0.001, ES=-2.47) on Sunday. Mean results showed children spent 91-96% of their time engaged in light or sedentary activities. Even during school playtime, where the children were most active, only 8 of 80 min were spent engaged in MVPA. this study found activity levels were considerably lower than the recommended guidelines, and children were more active during school playtime compared to after school and weekends.

    Introduction of biofortified cassava as school lunch can increase vitamin A intake, but may increase risk of other deficiencies due to poor nutrient profile of cassava. We assessed the potential effect of introducing a yellow cassava-based school lunch combined with additional food-based recommendations (FBR) on vitamin A and overall nutrient adequacy using Optifood (linear programming tool). Cross-sectional study to assess dietary intakes (24 h recall) and derive model parameters (list of foods consumed, median serving sizes, food and food (sub)group frequency distributions, food cost). Three scenarios were modelled, namely daily diet including: (i) no school lunch; (ii) standard 5d school lunch with maize/beans; and (iii) 5d school lunch with yellow cassava. Each scenario and scenario 3 with additional FBR were assessed on overall nutrient adequacy using recommended nutrient intakes (RNI). Eastern Kenya. Primary-school children (n 150) aged 7-9 years. Best food pattern of yellow cassava-based lunch scenario achieved 100 % RNI for six nutrients compared with no lunch (three nutrients) or standard lunch (five nutrients) scenario. FBR with yellow cassava and including small dried fish improved nutrient adequacy, but could not ensure adequate intake of fat (52 % of average requirement), riboflavin (50 % RNI), folate (59 % RNI) and vitamin A (49 % RNI). Introduction of yellow cassava-based school lunch complemented with FBR potentially improved vitamin A adequacy, but alternative interventions are needed to ensure dietary adequacy. Optifood is useful to assess potential contribution of a biofortified crop to nutrient adequacy and to develop additional FBR to address remaining nutrient gaps.

  13. Rural origin plus a rural clinical school placement is a significant predictor of medical students' intentions to practice rurally: a multi-university study. (United States)

    Walker, Judith H; Dewitt, Dawn E; Pallant, Julie F; Cunningham, Christine E


    Health workforce shortages are a major problem in rural areas. Australian medical schools have implemented a number of rural education and training interventions aimed at increasing medical graduates' willingness to work in rural areas. These initiatives include recruiting students from rural backgrounds, delivering training in rural areas, and providing all students with some rural exposure during their medical training. However there is little evidence regarding the impact of rural exposure versus rural origin on workforce outcomes. The aim of this study is to identify and assess factors affecting preference for future rural practice among medical students participating in the Australian Rural Clinical Schools (RCS) Program. Questionnaires were distributed to 166 medical students who had completed their RCS term in 2006; 125 (75%) responded. Medical students were asked about their preferred location and specialty for future practice, their beliefs about rural work and life, and the impact of the RCS experience on their future rural training and practice preferences. Almost half the students (47%; n=58) self-reported a 'rural background'. Significantly, students from rural backgrounds were 10 times more likely to prefer to work in rural areas when compared with other students (ppreferring general practice, 80% (n=24) wished to do so rurally. Eighty-five per cent (n=105) of students agreed that their RCS experience increased their interest in rural training and practice with 62% (n=75) of students indicating a preference for rural internship/basic training after their RCS experience. A substantial percentage (86%; n=108) agreed they would consider rural practice after their RCS experience. This baseline study provides significant evidence to support rural medical recruitment and retention through education and training, with important insights into the factors affecting preference for future rural practice. By far the most significant predictor of rural practice

  15. Sex differences in general knowledge: meta-analysis and new data on the contribution of school-related moderators among high-school students. (United States)

    Tran, Ulrich S; Hofer, Agnes A; Voracek, Martin


    Research from various countries consistently reported an advantage of boys over girls in general knowledge and was also suggestive of some overall trends regarding specific domains of general knowledge that were speculated to stem from biologically differentiated interests. However, results were heterogeneous and, as of yet, had not been evaluated meta-analytically. Moreover, previous research drew on overly homogeneous high-school or undergraduate samples whose representativeness appears problematic; mostly, likely moderators, such as school type, student age or parental education, were also not directly investigated or controlled for. We provide a meta-analytical aggregation of available results regarding sex differences in general knowledge and present new data, investigating the psychometric properties of the General Knowledge Test (GKT), on which previous research primarily relied, and explored sex differences in a large and heterogeneous Austrian high-school student sample (N = 1088). The aggregated sex effect in general knowledge was of medium size in previous research, but differences in specific domains were heterogeneous across countries and only modest at best. Large sex differences in our data could be explained to a large part by school-related moderators (school type, school, student age, parental education) and selection processes. Boys had a remaining advantage over girls that was only small in size and that was consistent with the magnitude of sex differences in general intelligence. Analysis of the GKT yielded no evidence of biologically differentiated interests, but of a specific interest in the humanities among girls. In conclusion, previous research likely overestimated sex differences in general knowledge.

  16. Contribution of the Nordic School of Public Health to the public mental health research field: a selection of research initiatives, 2007-2014. (United States)

    Forsman, Anna K; Fredén, Lars; Lindqvist, Rafael; Wahlbeck, Kristian


    The field of public mental health has been defined by an expert group convened by the Nordic School of Public Health (NHV) as encompassing the experience, occurrence, distribution and trajectories of positive mental health and mental health problems and their determinants; mental health promotion and prevention of mental disorders; as well as mental health system policies, governance and organization. The mental health priorities of the Nordic Council of Ministers in 2010 signalled a mutual Nordic exchange of knowledge in the following thematic areas: child and adolescent mental health; working life and mental health; mental health in older people; strengthening the role of primary care in mental health service provision; stronger involvement of users and carers; and reduction of use of coercion in psychiatric care. Efforts to realize these priorities included commissioning the Nordic Research Academy for Mental Health, an NHV-based network of research institutions with a common interest in mental health research across the Nordic countries, to develop, organize and follow-up projects on public mental health. The research initiatives included mental health policy analysis, register-based research and research focused on the users' perspective in a Nordic context, as well as EU-level research policy analysis. The public mental health research conducted at the NHV highlighted the complexity of mental health and emphasized that the broad determinants of mental health need to be increasingly addressed in both public health research and practice. For example, health promotion actions, improved access to health care, a healthy alcohol policy and prevention of suicides and violence are all needed to reduce the life expectancy gap - a red flag indicator of public health inequalities. By exchanging knowledge and best practice, the collaboration between the Nordic countries contributes to the welfare of the region. The expertise and traditions developed at the NHV are of

    Full Text Available Objective.This work sought to determine the social representations conferred by caregivers, teachers, and children to food, health, and nutrition and the school breakfast program for children from three to seven years of age in the city of San Luis Potosí, San Luis Potosí, Mexico, through identifying a knowledge and practices and b meanings attributed on health and nutrition of children from three to seven years of age and on the school breakfast program. Methods. This was a qualitative health study. The sample included 33 mothers, 3 grandmothers, 1 father, 30 children from 3 to 7 years of age, and 8 teachers who signed an informed consent. The data were collected through a semi-structured interview and treated through content analysis modality thematic analysis. Results. The analysis yielded the categories: knowledge on food, the health-feeding relation, customs and practices of the child's feeding, and meanings of the school breakfast program. Conclusion. On the reflection on the representations of the different players included in the school breakfast program, elements become manifest that would support an educational intervention by nursing, which would have to be based on the family as the central figure to provide good nutrition and teach good habits.

  5. Contribution of formative research to design an environmental program for obesity prevention in schools in Mexico City. (United States)

    Bonvecchio, Anabelle; Théodore, Florence L; Safdie, Margarita; Duque, Tiffany; Villanueva, María Ángeles; Torres, Catalina; Rivera, Juan


    This paper describes the methods and key findings of formative research conducted to design a school-based program for obesity prevention. Formative research was based on the ecological model and the principles of social marketing. A mixed method approach was used. Qualitative (direct observation, indepth interviews, focus group discussions and photo-voice) and quantitative (closed ended surveys, checklists, anthropometry) methods were employed. Formative research key findings, including barriers by levels of the ecological model, were used for designing a program including environmental strategies to discourage the consumption of energy dense foods and sugar beverages. Formative research was fundamental to developing a context specific obesity prevention program in schools that seeks environment modification and behavior change.

    Full Text Available This article presents the results of a research which intended to identify the modifications that ocurred in the representations regarding the Physical education in the school of a group of classroom teachers that attended a Program of Academical Formation (named as PEC in municipal districts. The data, obtained by the Clinical Method, were confronted with the knowledge on the construtivist learning conception and on the pedagogic tendencies of the school Physical education. As relevant discoveries we detached the following modifications: from representations that reflected a vision dualist (body/mind to a technical vision (the body as tool or, from the latter to the sociocultural vision (the citizen body. The identified transformations accompanied the historical path of the Physical education in Brazil.

  7. Contribution of time-activity pattern and microenvironment to black carbon (BC) inhalation exposure and potential internal dose among elementary school children (United States)

    Jeong, Hyeran; Park, Donguk


    The aims of this study were to quantify the contributions of activities or microenvironments (MEs) to daily total exposure to and potential dose of black carbon (BC). Daily BC exposures (24-h) were monitored using a micro-aethalometer micoAeth AE51 with forty school-aged children living in an urban area in Korea from August 2015 to January 2016. The children's time-activity patterns and the MEs they visited were investigated by means of a time-activity diary (TAD) and follow-up interviews with the children and their parents. Potential inhaled dose was estimated by multiplying the airborne BC concentrations (μg/m3) we monitored for the time the children spent in a particular ME by the inhalation rate (IR, m3/h) for the time-activity performed. The contribution of activities and MEs to overall daily exposure to and potential dose of BC was quantified. Overall mean daily potential dose was equal to 24.1 ± 10.6 μg/day (range: 6.6-46.3 μg/day). The largest contribution to BC exposure and potential dose (51.9% and 41.7% respectively) occurred in the home thanks to the large amount of time spent there. Transportation was where children received the most intense exposure to (14.8%) and potential dose (20.2%) of BC, while it accounted for 7.6% of daily time. School on weekdays during the semester was responsible for 20.3% of exposure and 22.5% of potential dose. Contribution to BC exposure and potential dose was altered by several time-activity parameters, such as type of day (weekdays vs. weekends; school days vs. holidays), season, and gender. Traveling by motor vehicle and subway showed more elevated exposure or potential dose intensity on weekdays or school days, probably influenced by the increased surrounding traffic volumes on these days compared to on weekends or holidays. This study may be used to prioritize targets for minimizing children's exposure to BC and to indicate outcomes of BC control strategies.

    DEFF Research Database (Denmark)

    Okulov, Valery L.; van Kuik, Gijs A.M.


    The derivation of the efficiency of an ideal wind turbine has been attributed to the three famous scientists of the three aerodynamic research schools in Europe during the first decades of the previous century: Lanchester, Betz and Joukowsky. However, detailed reading of their classical papers has...... shown that Lanchester did not accept Froude's result that the velocity through the disc is the average of the velocities far upstream and far downstream, by which his solution is not determined. Betz and Joukowsky used vortex theory to support Froude's result and derived the ideal efficiency of a wind...

  10. The contribution to the research into the role of Bogdan Bogdanović in the creation of the New School of architecture in Belgrade

    Directory of Open Access Journals (Sweden)

    Folić Branislav


    Full Text Available Following student protests in 1968, the reform of universities began in Yugoslavia. The idea of the humanization of architectural profession and the reform of Belgrade Faculty of Architecture towards the environmental studies was launched. The article examines the impact of the New School on the humanization of the architectural profession as part of a general movement to humanize the society of the sixties, as well as the significant role of Bogdan Bogdanović in the realisation of such an endeavour. First steps towards creating a New School could be foreseen in Bogdan Bogdanović's text Arhitektura je nauka (The Architecture is a Science in 1969, which suggests the introduction of the humanistic disciplines in architectural education as well as in the analytical texts of Professor Branislav Milenković ”O nastavi na arhitekstonskom fakultetu” (About Teaching at the Faculty of Architecture, 1945-1968 and assistant lecturer Ranko Radović ”Učenje neimarstva” published in the magazine Arhitektura-urbanizam (Architecture-Town Planning No.52 in 1968. During his stay in America, Bogdanović gained some experience visiting multidisciplinary schools of environmental design. Analyzing the school curriculum and current trends in the education of architects, he set the basis for the application of environmental design. The reform was carried out transparently with equal participation of students, teachers and former students of the Faculty of Architecture. The team for the creation of the New School, led by Bogdan Bogdanović, after each meeting published announcements that contained conclusions on the implementation of reforms. These announcements and processed materials represented the content basis of the New School of architecture.

  11. The Interdisciplinarity in the Students' Questions in Science Classes of the Elementary School: Contributions of Discursive Textual Analysis

    Directory of Open Access Journals (Sweden)

    Maurivan Güntzel Ramos


    Full Text Available The article presents the analysis of 342 questions on the theme "Water", proposed by 114 students from three elementary schools in the South region of Brazil, in order to identify interdisciplinary articulations associated with complex thinking present in these questions. The research sought to answer the following question: What revelations can emerge from the analysis of student's questions about a specific topic of study, such as "Water", in relation to interdisciplinarity and complex thinking? From the discursive textual analysis of the questions, two categories emerged: disciplinary questions; and interdisciplinary questions. The examination of the content of the categories enabled the writing of metatexts that reveal that in the text of most of the students' questions, is present a complex mode of thinking and interdisciplinary relationships, since 77.8% of the questions belong to second category. This can be an indication to teachers of how to initiate pedagogical actions, whose focus is interdisciplinarity.

  12. Female high school biology students' biofilm-focused learning: The contributions of three instructional strategies to patterns in understanding and motivation (United States)

    Ales, Jo Dale Hill


    This exploratory study examined three instructional strategies used with female high school biology students. The relative contributions of the strategies to student understanding of microbiology and motivation in science were analyzed. The science education community targeted underachievement in science by implementing changes in content and practices (NRC, 1996). Research suggested that teachers facilitate learnirig environments based on human constructivism (Mintzes, Wandersee, & Novak, 1997) that is rooted in meaningful learning theory (Ausubel, Novak & Hanesian, 1978). Teachers were advised to use both visual and verbal instructional strategies (Paivio, 1983) and encourage students to construct understandings by connecting new experiences to prior knowledge. The American Society for Microbiology supports the study of microorganisms because of their prominence in the biosphere (ASK 1997). In this study, two participating teachers taught selected microbiology concepts while focused on the cutting edge science of biofilms. Biology students accessed digitized biofilm images on an ASM web page and adapted them into products, communicated with biofilm researchers, and adapted a professional-quality instructional video for cross-age teaching. The study revealed improvements in understanding as evidenced on a written test; however, differences in learnirig outcomes were not significant. Other data, including student journal reflections, observations of student interactions, and student clinical interviews indicate that students were engaged in cutting edge science and adapted biofilm images in ways that increased understanding of microbiology (with respect to both science content and as a way of knowing) and motivation. An ASM CD-ROM of the images did not effectively enhance learning and this study provides insights into what could make it more successful. It also identifies why, in most cases, students' E-mail communication with biofilm researchers was unsuccessful

    Gislaine Ricci Leonardi


    Full Text Available Skin cancer Primary prevention should focus young populations, using the school and teachers as strategic players. This paper describes results from a project aimed to educate kindergarten teachers in the Diadema municipality (metropolitan S Paulo about photoeducation and sun exposure risks. The intervention was based on an investigation about teachers level of knowledge. Analysis revealed several gaps in knowledge topics - effects of skin tanning; sun exposure damage different than skin cancer; forms of sun protection, other than sunscreens; importance of sunscreen in childhood; types of solar radiation and their effects on human health; facts to be observed in the use of sunscreens. Based on the results of the first step, educational intervention was performed. The last step involved the evaluation of acquired knowledge. The collecting data technique was the Focal Group. Through content analysis, advances in knowledge and the acquisition of concepts were identified. The educational intervention was determinant for teachers knowledge especially regarding UVt radiation types and sun protection factors, but also revealed some pitfalls. In conclusion, short-term actions may be sufficient to transform some concepts but not enough to achieve all goals, especially the transformation of concepts related to cultural aspects, demanding greater daily educational investments.

  17. Using smart card technology to monitor the eating habits of children in a school cafeteria: 3. The nutritional significance of beverage and dessert choices. (United States)

    Lambert, N; Plumb, J; Looise, B; Johnson, I T; Harvey, I; Wheeler, C; Robinson, M; Rolfe, P


    The consumption patterns of beverages and desserts features highly in the current debate surrounding children's nutrition. The aim of this study was to continuously monitor the choice of beverages and desserts made by nearly 1000 children in a school cafeteria. A newly developed smart card system was used to monitor the food choices of diners (7-16-year-old boys) in a school cafeteria over 89 days. A wide variety of beverages and desserts were on offer daily. Despite coming from an affluent, well-educated demographic group, the boys' choices of beverages and desserts mirrored those of children in general. Buns and cookies were over 10 times more popular than fresh fruits and yogurts. Sugary soft-drinks were over 20 times more popular than fresh fruit drinks and milk combined. Appropriate choices could, over a month, reduce intake of added sugar by over 800 g and fat by over 200 g. The smart card system was very effective at monitoring total product choices for nearly 1000 diners. In agreement with a recent national school meal survey, where choice is extensive, children show a preference for products high in fat and/or sugar. The consequences of these preferences are discussed.

  18. Implications of the cognitive dimension of art in artistic scenic education. Some contributions for the teacher in scenic arts at the high school level.

    Directory of Open Access Journals (Sweden)

    Carolina Merchan Price


    Full Text Available In this work we explore the contributions proposed by Arthur Efland (especially those of his book Art and Cognition, with the aim of broadening the statements of the academic programmes in performing arts as a curriculum area in the scholar plan, and also within the frame of teacher training. In this perspective, we consider the concept of cognition towards those experiences and subsequent learning in which the body plays a central role as mediator in the process of understanding of the world itself. We also discuss during the analysis the role of the emotions in thought processes. In this sense, we propose to use this new perspective of complementary interaction between the emotional and intellectual dimensions to discuss the concepts of creation, appreciation and understanding, typical of artistic fields and their teaching. We propose this complementary interaction as a fundamental process of the encounter of arts, in the dynamics of development in the school. In the conclusions, we open the possibility of a need to redefine the conceptual axes to train teachers in performing arts, articulating specific disciplinary knowledge of performing arts with the needs of the scholar project itself, particularly those linked to the social and individual development of the person in the frame of basic and intermediate school.

  1. Which sociodemographic factors are important on smoking behaviour of high school students? The contribution of classification and regression tree methodology in a broad epidemiological survey. (United States)

    Ozge, C; Toros, F; Bayramkaya, E; Camdeviren, H; Sasmaz, T


    The purpose of this study is to evaluate the most important sociodemographic factors on smoking status of high school students using a broad randomised epidemiological survey. Using in-class, self administered questionnaire about their sociodemographic variables and smoking behaviour, a representative sample of total 3304 students of preparatory, 9th, 10th, and 11th grades, from 22 randomly selected schools of Mersin, were evaluated and discriminative factors have been determined using appropriate statistics. In addition to binary logistic regression analysis, the study evaluated combined effects of these factors using classification and regression tree methodology, as a new statistical method. The data showed that 38% of the students reported lifetime smoking and 16.9% of them reported current smoking with a male predominancy and increasing prevalence by age. Second hand smoking was reported at a 74.3% frequency with father predominance (56.6%). The significantly important factors that affect current smoking in these age groups were increased by household size, late birth rank, certain school types, low academic performance, increased second hand smoking, and stress (especially reported as separation from a close friend or because of violence at home). Classification and regression tree methodology showed the importance of some neglected sociodemographic factors with a good classification capacity. It was concluded that, as closely related with sociocultural factors, smoking was a common problem in this young population, generating important academic and social burden in youth life and with increasing data about this behaviour and using new statistical methods, effective coping strategies could be composed.

  3. Component analysis of a school-based substance use prevention program in Spain: contributions of problem solving and social skills training content. (United States)

    Espada, José P; Griffin, Kenneth W; Pereira, Juan R; Orgilés, Mireia; García-Fernández, José M


    The objective of the present research was to examine the contribution of two intervention components, social skills training and problem solving training, to alcohol- and drug-related outcomes in a school-based substance use prevention program. Participants included 341 Spanish students from age 12 to 15 who received the prevention program Saluda in one of four experimental conditions: full program, social skills condition, problem solving condition, and a wait-list control group. Students completed self-report surveys at the pretest, posttest and 12-month follow-up assessments. Compared to the wait-list control group, the three intervention conditions produced reductions in alcohol use and intentions to use other substances. The intervention effect size for alcohol use was greatest in magnitude for the full program with all components. Problem-solving skills measured at the follow-up were strongest in the condition that received the full program with all components. We discuss the implications of these findings, including the advantages and disadvantages of implementing tailored interventions to students by selecting intervention components after a skills-based needs assessment.

  9. School Breakfast Program and school performance. (United States)

    Meyers, A F; Sampson, A E; Weitzman, M; Rogers, B L; Kayne, H


    To test the hypothesis that participation in the School Breakfast Program by low-income children is associated with improvements in standardized achievement test scores and in rates of absence and tardiness, children in grades 3 through 6 were studied in the Lawrence, Mass, public schools, where the School Breakfast Program was begun at the start of the second semester 1986-1987 school year. The changes in scores on a standardized achievement test and in rates of absence and tardiness before and after the implementation of the School Breakfast Program for children participating in the program were compared with those of children who also qualified but did not participate. Controlling for other factors, participation in the School Breakfast Program contributed positively to the 1987 Comprehensive Tests of Basic Skills battery total scale score and negatively to 1987 tardiness and absence rates. These findings suggest that participation in the School Breakfast Program is associated with significant improvements in academic functioning among low-income elementary school children.

  13. Contribuições da racionalidade argumentativa para a abordagem da ética na escola Contributions of argumentative rationality for addressing ethics in school

    Directory of Open Access Journals (Sweden)

    Renato José de Oliveira


    of the model of demonstrative rationality, prevalent since the advent of modernity. Alternatively, it presents another model, the argumentative rationality one, which is discussed with basis on the approaches taken by Chaïm Perelman, Lucie Olbrechts-Tyteca and Michel Meyer. The first two authors have formulated a theory of argumentation whose goal is to support the typical reasoning of human and social sciences, knowledge areas in which typical procedures of demonstrative rationality, such as deduction and calculation do not apply. Meyer stresses the problematizing nature of argumentative rationality, placing the rhetoric as a means of negotiating the distance between individuals in regard to certain issues. This theoretical framework is complemented by the philosophy of pluralism appointed by Perelman as a counterpoint to the worldviews grounded on unitary conceptions of truth, called monisms. In this theoretical framework, I discuss the universalistic ethical concept of Kant and the relativism proposed by the ethics of aesthetics defended by Maffesoli. In a second topic, ethics in school education is problematized in view of the question: how can one shape the character of the student without falling into some sort of indoctrination? To the extent that ethics and morality relate to this question, I discuss how the two terms have been understood and I propose to regard them as interchangeable instances. The conclusions I present based on these discussions aim not to solve the problems inherent in the habits and attitudes of students, but to contribute to teachers' reflection about their teaching practices.

  15. Availability of Vending Machines and School Stores in California Schools. (United States)

    Cisse-Egbuonye, Nafissatou; Liles, Sandy; Schmitz, Katharine E; Kassem, Nada; Irvin, Veronica L; Hovell, Melbourne F


    This study examined the availability of foods sold in vending machines and school stores in United States public and private schools, and associations of availability with students' food purchases and consumption. Descriptive analyses, chi-square tests, and Spearman product-moment correlations were conducted on data collected from 521 students aged 8 to 15 years recruited from orthodontic offices in California. Vending machines were more common in private schools than in public schools, whereas school stores were common in both private and public schools. The food items most commonly available in both vending machines and school stores in all schools were predominately foods of minimal nutritional value (FMNV). Participant report of availability of food items in vending machines and/or school stores was significantly correlated with (1) participant purchase of each item from those sources, except for energy drinks, milk, fruits, and vegetables; and (2) participants' friends' consumption of items at lunch, for 2 categories of FMNV (candy, cookies, or cake; soda or sports drinks). Despite the Child Nutrition and Women, Infants, and Children (WIC) Reauthorization Act of 2004, FMNV were still available in schools, and may be contributing to unhealthy dietary choices and ultimately to health risks. © 2015, American School Health Association.

  17. Requirements to nuclear power to significantly contribute to decarbonization

    Energy Technology Data Exchange (ETDEWEB)

    Zipper, Reinhard [Forschungs- und Technologieberatung Zipper (FTBZ), Haan (Germany)


    By the end of the UN Climate Conference 2015 in Paris all members agreed to take action with the goal to limit climate warming to less than 2 C compared to pre-industrial status. CO{sub 2} emissions are supposed to be the main driver of climate change. This implies that all kinds of energy supply must be reengineered to avoid deployment of fossil fuels as far as practicable. Nuclear energy has a minimal CO{sub 2} footprint and with the ability to flexibly adjust to the individual demands of supply regions it may be favored to play a major role in decarbonization. However, on this path some principal obstacles must be removed to gain general public, policy and industry acceptance.

  1. Progression of impairment in adolescents with attention-deficit/hyperactivity disorder through the transition out of high school: Contributions of parent involvement and college attendance. (United States)

    Howard, Andrea L; Strickland, Noelle J; Murray, Desiree W; Tamm, Leanne; Swanson, James M; Hinshaw, Stephen P; Arnold, L Eugene; Molina, Brooke S G


    Long-term, prospective follow-up studies of children diagnosed with attention-deficit/hyperactivity disorder (ADHD) show that symptoms tend to decline with age, but impairments in daily life functioning often persist into adulthood. We examined the developmental progression of impairments before and after the transition out of high school in relation to parent involvement during adolescence, parent support during adulthood, and college attendance, using 8 waves of data from the prospective 16-year follow-up of the Multimodal Treatment of ADHD (MTA) study. Participants were 548 proband children diagnosed with Diagnostic and Statistical Manual of Mental Disorders (4th ed., text rev.; DSM-IV; American Psychiatric Association, 2000) ADHD Combined Type and 258 age- and sex-matched comparison children (Local Normative Comparison Group; LNCG) randomly sampled from probands' schools. Impairment was assessed consistently by parent report from childhood through adulthood. Results showed that impairment worsens over time both before and after the transition to adulthood for those with ADHD histories, in contrast to non-ADHD peers, whose impairments remained stably low over time. However, impairment stabilized after leaving high school for young adults with ADHD histories who attended college. Involved parenting in adolescence was associated with less impairment overall. Attending college was associated with a stable post-high school trajectory of impairment regardless of parents' involvement during adolescence, but young adults with histories of involved parenting and who attended college were the least impaired overall.

  5. The influence of school culture and school climate on violence in schools of the Eastern Cape Province

    Directory of Open Access Journals (Sweden)

    Kalie Barnes


    Full Text Available This article reports on research undertaken about the influence of school culture and school climate on violence at schools in the Eastern Cape. An adapted California School Climate and Survey - Short Form (CSCSS-SF, which was used as the data-collection instrument, was completed by 900 Grade 10 to 12 learners. With the assistance of Pearson's product moment correlation coefficient, it was found that the better the school culture and school climate are at a school, the lower the levels of school violence. On the other hand, a lack of school safety contributed to learners experiencing higher levels of violence at schools. The results of hierarchy regression analyses indicated that school culture and school climate can be used to explain a significant percentage of variance in school violence. The f² values indicate that, with the exception of two aspects of the variance physical and verbal harassment, the results did not have any practical value. The article concludes with a few suggestions on how the results can be used to address school violence.

  6. School environment and school injuries

    Directory of Open Access Journals (Sweden)

    Simo eSalminen


    Full Text Available Background: Although injuries at school are an important issue in public health, environmental factors in schools and school yards have seldom been the focus of school injury research. The goal of our investigation was to examine the effect of environmental factors on school injuries. Methods: Nine comprehensive Finnish schools registered school injuries over a period of two school years. Injuries were classified as being associated with environmental factors, suspected environmental factors, and others. The consensus between two independent classifiers was 81%. Results: A total of 722 injuries were classified. In 11.6% of these injuries, the physical environment factor was evident, and in 28.1% of the injuries, physical environment was suspected of being a contributory risk factor. Thus the physical environment of the school was a contributing factor in over a third (39.7% of injuries occurring in the school, on the school yard or during the journey to or from school. In this study, conducted in Finland, ice on the ground was mentioned most frequently as an environmental risk factor. Conclusions: In Finland, the Nordic weather conditions are not taken into account in the school yard and playground plans as they ought to from the safety point of view. An initiative has been launched on a mandatory wintertime master plan for every school yard.

  7. Significant Tsunami Events (United States)

    Dunbar, P. K.; Furtney, M.; McLean, S. J.; Sweeney, A. D.


    Tsunamis have inflicted death and destruction on the coastlines of the world throughout history. The occurrence of tsunamis and the resulting effects have been collected and studied as far back as the second millennium B.C. The knowledge gained from cataloging and examining these events has led to significant changes in our understanding of tsunamis, tsunami sources, and methods to mitigate the effects of tsunamis. The most significant, not surprisingly, are often the most devastating, such as the 2011 Tohoku, Japan earthquake and tsunami. The goal of this poster is to give a brief overview of the occurrence of tsunamis and then focus specifically on several significant tsunamis. There are various criteria to determine the most significant tsunamis: the number of deaths, amount of damage, maximum runup height, had a major impact on tsunami science or policy, etc. As a result, descriptions will include some of the most costly (2011 Tohoku, Japan), the most deadly (2004 Sumatra, 1883 Krakatau), and the highest runup ever observed (1958 Lituya Bay, Alaska). The discovery of the Cascadia subduction zone as the source of the 1700 Japanese "Orphan" tsunami and a future tsunami threat to the U.S. northwest coast, contributed to the decision to form the U.S. National Tsunami Hazard Mitigation Program. The great Lisbon earthquake of 1755 marked the beginning of the modern era of seismology. Knowledge gained from the 1964 Alaska earthquake and tsunami helped confirm the theory of plate tectonics. The 1946 Alaska, 1952 Kuril Islands, 1960 Chile, 1964 Alaska, and the 2004 Banda Aceh, tsunamis all resulted in warning centers or systems being established.The data descriptions on this poster were extracted from NOAA's National Geophysical Data Center (NGDC) global historical tsunami database. Additional information about these tsunamis, as well as water level data can be found by accessing the NGDC website

  8. Student engagement and its relationship with early high school dropout. (United States)

    Archambault, Isabelle; Janosz, Michel; Fallu, Jean-Sébastien; Pagani, Linda S


    Although the concept of school engagement figures prominently in most school dropout theories, there has been little empirical research conducted on its nature and course and, more importantly, the association with dropout. Information on the natural development of school engagement would greatly benefit those interested in preventing student alienation during adolescence. Using a longitudinal sample of 11,827 French-Canadian high school students, we tested behavioral, affective, cognitive indices of engagement both separately and as a global construct. We then assessed their contribution as prospective predictors of school dropout using factor analysis and structural equation modeling. Global engagement reliably predicted school dropout. Among its three specific dimensions, only behavioral engagement made a significant contribution in the prediction equation. Our findings confirm the robustness of the overall multidimensional construct of school engagement, which reflects both cognitive and psychosocial characteristics, and underscore the importance attributed to basic participation and compliance issues in reliably estimating risk of not completing basic schooling during adolescence.

  9. Young science journalism: writing popular scientific articles may contribute to an increase of high-school students' interest in the natural sciences (United States)

    Simon, Uwe K.; Steindl, Hanna; Larcher, Nicole; Kulac, Helga; Hotter, Annelies


    Far too few high-school students choose subjects from the natural sciences (NaSc) for their majors in many countries. Even fewer study biology, chemistry or physics at university. Those, that do, often lack training to present and discuss scientific results and ideas in texts. To meet these challenges the center for didactics of biology of Graz University has set up the program Young Science Journalism. This new workshop-based interdisciplinary concept was tested in an exploratory study with grade 10 students of one Austrian high school, engaging both the biology and the German teacher of the class. It was our aim to raise students' interest in the NaSc by encouraging them to write popular scientific articles about self-chosen topics, and to help them improve their writing competence. In this paper we focus on interest development through writing. Results from this pilot study were promising. Using a mixed-method approach (comparing pre- and post-test questionnaires and semi-structured interviews from different time points analyzed qualitatively), we found that almost all students valued the project-related work highly. Most of them showed higher interest in the NaSc at project end with girls, in average, seeming to profit more from project participation. We thus recommend integrating such writing tasks into school curricula to increase students' interest in NaSc or to even create new interest. Additionally, we introduce a network presentation of questionnaire data as a powerful tool to visualize the effect of an intervention on individual students and student profile groups. This paper is part of a series accompanying the Austrian Young Science Journalism program.

  10. Factors contributing to adolescent obesity. (United States)

    Al-Kloub, Manal I; Froelicher, Erika S


    Obesity in children is a significant public health concern. The prevalence of overweight and obesity in Jordanian children, and adolescents has increased in the last decade. The consequences of obesity to health in childhood and adulthood have both medical, and economic cost to individuals and society. This paper reviews the factors that contribute to adolescent obesity and emphasizes behavioral and environmental factors. An individual's behaviors such as increased consumption of high caloric foods, increased sedentary activity while decreasing physical activity has been identified as key issues in the development of obesity. Additionally, the current environment in homes, schools, and neighborhoods tend to discourage a healthy lifestyle. A comprehensive approach that involves the whole community is the best strategy for preventing adolescent obesity. Nurses are in a unique position to provide leadership in developing programs for healthier lifestyle choices for adolescents' and adoption of these goals into their daily lives.

    Full Text Available This work points to the articulations between the fundamentals of cultural-historical psychology and the historical-critical pedagogy, in regard the issue of content that should compose the curriculum. The correct organization of the teaching process by the teacher, through scientific knowledge, as well as the appropriation of classic content, by students, promotes mental development to raise the development of higher psychological functions at their highest possibilities. Thus, we affirm the cultural-historical psychology and the historical-critical pedagogy align themselves both with regard to the Marxist perspective of socialist revolution, as in respect to concept of formation of individuality and the role of schooling in human emancipation.

  16. Social Contributions in Romania

    Attila Gyorgy


    Full Text Available Social contributions have an important impact on payroll policy. Also, social contributions represent a significant budgetary revenue item which can be viewed at the edge between taxation and insurance. Social contributions in Romania experienced many changes which ended in 2008. Nowadays, they are within a long transaction period towards partial externalization of the insurance activity to privately managed funds. The aim of this paper is to analyse the homogeneity of Romanian social security public scheme using annual data extracted from 2002-2009.The main findings reveal that social contributions reached the pinnacle of diversification, being too many, some of them with a small contribution rates; fiscal reforms which reduced contribution rates advantaged employers, and state will be interested to externalize this activity as far private sector will be able to assume this responsibility and the budgetary effects are acceptable for the public finance.

  17. School variation in asthma: compositional or contextual?

    Directory of Open Access Journals (Sweden)

    Tracy K Richmond


    Full Text Available Childhood asthma prevalence and morbidity have been shown to vary by neighborhood. Less is known about between-school variation in asthma prevalence and whether it exists beyond what one might expect due to students at higher risk of asthma clustering within different schools. Our objective was to determine whether between-school variation in asthma prevalence exists and if so, if it is related to the differential distribution of individual risk factors for and correlates of asthma or to contextual influences of schools.Cross-sectional analysis of 16,640 teens in grades 7-12 in Wave 1 (data collected in 1994-5 of the National Longitudinal Study of Adolescent Health. Outcome was current diagnosis of asthma as reported by respondents' parents. Two-level random effects models were used to assess the contribution of schools to the variance in asthma prevalence before and after controlling for individual attributes.The highest quartile schools had mean asthma prevalence of 21.9% compared to the lowest quartile schools with mean asthma prevalence of 7.1%. In our null model, the school contributed significantly to the variance in asthma (sigma(u0(2 = 0.27, CI: 0.20, 0.35. Controlling for individual, school and neighborhood attributes reduced the between-school variance modestly (sigma(u0(2 = 0.19 CI: 0.13-0.29.Significant between-school variation in current asthma prevalence exists even after controlling for the individual, school and neighborhood factors. This provides evidence for school level contextual influences on asthma. Further research is needed to determine potential mechanisms through which schools may influence asthma outcomes.

    Full Text Available Current analysis recovers basic assumptions of functionality, specifically the functionality of the Western Coast of the United States and discusses the implications of the approach in the teaching and learning of Portuguese. Investigation is illustrated by proposals of linguistic analysis of texts featuring cooking recipes, applied to 8th and 9th year students of the Brazilian elementary, based on two central themes of functionality, or rather, iconicity and grammaticalization. Discussions indicate that, within the context of iconicity and grammaticalization concepts suggested by functionality, the activities of linguistic analysis in lessons of the mother language contribute so that students may acknowledge that the grammar of language is heterogeneous, flexible and determined through usage in day-to-day communicative interactions.

    Full Text Available Although several studies have recently assessed direct self-injurious behavior (D-SIB among adolescents, it is still understudied in adolescents attending vocational schools: an educational setting generally associated with lower socioeconomic status. After extending the “Saving and Empowering Young Lives in Europe” (SEYLE project to a vocational school population, we examined their D-SIB and life event characteristics compared to the high school population. SEYLE’s Hungarian randomly selected high school sample (N = 995 was completed with a randomly selected vocational school sample (N = 140 in Budapest, Hungary. Participants aged 14–17 years completed the SEYLE project’s self-administered questionnaires. D-SIB lifetime prevalence was significantly higher (29.4% in the vocational school group compared to the high school group (17.2% (Χ2(1 = 12.231, p< 0.001. D-SIB was associated with suicidal ideation in the vocational school group. Different life events were more frequent in the high school than in the vocational school group, and associations between D-SIB and life events differed in the vocational school group compared to the high school group. In conclusion, vocational school students are a vulnerable population with a higher prevalence of D-SIB compared to high school students. Life events and their association with D-SIB also differ in vocational school students compared to high school students. Taking all these into account might contribute to prevention/intervention designed for this population.

    The first Polish Higher Mining School was founded in 1816 in Kielce. The historical background of its foundation is described, curricula are outlined, prominent professors and graduates named. The significance of this School for Polish geology, mining and metallurgy to the present day is stressed. The School was closed in 1826 and the next Mining School to contine its traditions was instituted not earlier than in 1889 in Dabrowa Gornicza. It was also known as the Mine Foreman or Mine Deputy School (Sztygarka). This School was closed in 1905, reopened in 1910 and closed again in 1914. After Poland regained independence in 1919 the School flourished for 20 years. During the Second World War the teaching staff and student body were decimated and facilities destroyed. After 1945 the School was rebuilt and developed into an engineering school as a branch of the Academy of Mining and Metallury in Cracow by 1968 and a branch of the Silesian Politechnical between 1968 and 1984. In 1985 the School was taken over by the Ministry of Mining and Power Engineering and reorganized as a mining trade school. The Mining School in Dabrowa Gornicza, where several prominent professors of geology and managers of Polish geological and mining enterprises began their careers, contributed greatly to the development of geology in Poland. 12 refs.

  8. Detecting Novelty and Significance (United States)

    Ferrari, Vera; Bradley, Margaret M.; Codispoti, Maurizio; Lang, Peter J.


    Studies of cognition often use an “oddball” paradigm to study effects of stimulus novelty and significance on information processing. However, an oddball tends to be perceptually more novel than the standard, repeated stimulus as well as more relevant to the ongoing task, making it difficult to disentangle effects due to perceptual novelty and stimulus significance. In the current study, effects of perceptual novelty and significance on ERPs were assessed in a passive viewing context by presenting repeated and novel pictures (natural scenes) that either signaled significant information regarding the current context or not. A fronto-central N2 component was primarily affected by perceptual novelty, whereas a centro-parietal P3 component was modulated by both stimulus significance and novelty. The data support an interpretation that the N2 reflects perceptual fluency and is attenuated when a current stimulus matches an active memory representation and that the amplitude of the P3 reflects stimulus meaning and significance.

  10. The impact of personal background and school contextual factors on academic competence and mental health functioning across the primary-secondary school transition. (United States)

    Vaz, Sharmila; Parsons, Richard; Falkmer, Torbjörn; Passmore, Anne Elizabeth; Falkmer, Marita


    Students negotiate the transition to secondary school in different ways. While some thrive on the opportunity, others are challenged. A prospective longitudinal design was used to determine the contribution of personal background and school contextual factors on academic competence (AC) and mental health functioning (MHF) of 266 students, 6-months before and after the transition to secondary school. Data from 197 typically developing students and 69 students with a disability were analysed using hierarchical linear regression modelling. Both in primary and secondary school, students with a disability and from socially disadvantaged backgrounds gained poorer scores for AC and MHF than their typically developing and more affluent counterparts. Students who attended independent and mid-range sized primary schools had the highest concurrent AC. Those from independent primary schools had the lowest MHF. The primary school organisational model significantly influenced post-transition AC scores; with students from Kindergarten--Year 7 schools reporting the lowest scores, while those from the Kindergarten--Year 12 structure without middle school having the highest scores. Attending a school which used the Kindergarten--Year 12 with middle school structure was associated with a reduction in AC scores across the transition. Personal background factors accounted for the majority of the variability in post-transition AC and MHF. The contribution of school contextual factors was relatively minor. There is a potential opportunity for schools to provide support to disadvantaged students before the transition to secondary school, as they continue to be at a disadvantage after the transition.

  17. Sleep, sleepiness and school start times: a preliminary study. (United States)

    Dexter, Donn; Bijwadia, Jagdeep; Schilling, Dana; Applebaugh, Gwendolyn


    High school students are reported to be excessively sleepy, resulting in decreased academic performance, increased psycho-social problems and increased risk of morbidity and mortality from accidents. Early school start times have been noted to contribute to this problem. This report attempts to confirm the relationship of early school start times with decreased sleep and increased sleepiness. We examined sophomore and junior students in 2 local high schools with different start times and measured the amount of time slept and sleepiness. We found that students at the early start school reported reduced sleep time and more sleepiness than their counterparts at the later starting school. Early school start times are associated with student reports of less sleep and increased sleepiness. Further studies in larger groups are recommended in view of the potential significant impact of sleep deprivation in this age group.

    The Utility School of Southern Song Dynasty, represented by Chen Liang and Ye Shi, argues against spiritual mediation and temperal development for practical utility and usefulness. Their economic ethical thoughts, including equal emphasis on agriculture and commerce, practitioners of four industries having equal status, wealth to be stored in civilians and the protection of properties, nourished people's pursuit of richness in east Zhejiang and exerted profound influences on local commercial economic development and prosperity. In addition, the consistency of the School's utilitarian economic ethics with commercial economy development to certain extent inspires us to rethink Max Webber's remarks on the "hindering"of Confucian ethics on market economy forming de development.%以陈亮和叶适等人为代表的南宋事功学派,一反理学强调心性修养的治学倾向,公开倡导以务实事、求实功为宗旨的事功伦理,特别是农商并重、四民平等、藏富于民和保护富人等经济伦理思想,不仅滋养了重利富民的浙东精神,对浙东地区商品经济的发展和繁荣也产生了深远影响。同时,这一具有浓厚事功色彩的经济伦理与商品经济发展之间的某种契合关系也在一定程度上为重新思考马克斯·韦伯关于儒家伦理阻碍市场经济形成和发展的论断提供了有益的启示。

  19. Panel acoustic contribution analysis. (United States)

    Wu, Sean F; Natarajan, Logesh Kumar


    Formulations are derived to analyze the relative panel acoustic contributions of a vibrating structure. The essence of this analysis is to correlate the acoustic power flow from each panel to the radiated acoustic pressure at any field point. The acoustic power is obtained by integrating the normal component of the surface acoustic intensity, which is the product of the surface acoustic pressure and normal surface velocity reconstructed by using the Helmholtz equation least squares based nearfield acoustical holography, over each panel. The significance of this methodology is that it enables one to analyze and rank relative acoustic contributions of individual panels of a complex vibrating structure to acoustic radiation anywhere in the field based on a single set of the acoustic pressures measured in the near field. Moreover, this approach is valid for both interior and exterior regions. Examples of using this method to analyze and rank the relative acoustic contributions of a scaled vehicle cabin are demonstrated.

    The world-wide heating up of the atmosphere as well as the increasing violence and frequency of extreme weather events mainly are due to the emission of carbon dioxide. The emission of carbon dioxide is based on the power production by combustion of fossil sources of energy. The motor traffic causes a substantial portion of these emissions. Under this aspect, the author of the contribution under consideration examines, to what extent young people are sensitized to the relation between power generation by burning fossil sources of energy and the global climatic change and to ecological acting. In the context of the environment project 'Biodiesel as a pollution-free alternative to mineral diesel oil', 55 young people were informed about these relations and interviewed afterwards. After this project, a fifth of the young people transferred to economical diesel engined vehicles. A third of the young person wants to drive with biodiesel based on economic considerations. Young peoples only have a small amount of knowledge on these relations. Only those young people, who drive with biodiesel, are informed better significantly.

  3. Assessment of School Image

    Directory of Open Access Journals (Sweden)

    Ludvík Eger


    Full Text Available There seems to be a gap in the literature on educational management that focuses on school image and its assessment. This paper addresses this issue by reviewing the state of the art regarding school image and communication with the public.School image can be defined as the overall impression and mosaic synthesised from numerous impressions of individuals of school publics (pupils/students, teachers and deputies of school management, parents, and other stakeholders. School image is not what the headteachers understand it to be, but the feelings and beliefs about the school and its educational programme that exist in the minds of the school publics. The present study contributes to the literature by providing an overview of school image and by providing a practical application of a useful tool for assessing the content of corporate image. Semantic differential scales are used for marketing purposes and as a useful technique for measuring and assessing school image. Communication with publics and the development and sustainability of a positive school image influence not only the marketing of the school but also the educational process in the school. Today, shaping and maintaining a school image is even more important because of the curriculum reform, focusing on higher study process outputs, quality assessments, and accountability. The findings of this study have important implications for school marketing experts and researchers, headteachers, education policymakers, as well as teachers at schools.

  4. Testing Significance Testing

    Directory of Open Access Journals (Sweden)

    Joachim I. Krueger


    Full Text Available The practice of Significance Testing (ST remains widespread in psychological science despite continual criticism of its flaws and abuses. Using simulation experiments, we address four concerns about ST and for two of these we compare ST’s performance with prominent alternatives. We find the following: First, the 'p' values delivered by ST predict the posterior probability of the tested hypothesis well under many research conditions. Second, low 'p' values support inductive inferences because they are most likely to occur when the tested hypothesis is false. Third, 'p' values track likelihood ratios without raising the uncertainties of relative inference. Fourth, 'p' values predict the replicability of research findings better than confidence intervals do. Given these results, we conclude that 'p' values may be used judiciously as a heuristic tool for inductive inference. Yet, 'p' values cannot bear the full burden of inference. We encourage researchers to be flexible in their selection and use of statistical methods.

    Nirula, Ram; Talmor, Daniel; Brasel, Karen


    Identification of motor vehicle crash (MVC) characteristics associated with thoracoabdominal injury would advance the development of automatic crash notification systems (ACNS) by improving triage and response times. Our objective was to determine the relationships between MVC characteristics and thoracoabdominal trauma to develop a torso injury probability model. Drivers involved in crashes from 1993 to 2001 within the National Automotive Sampling System were reviewed. Relationships between torso injury and MVC characteristics were assessed using multivariate logistic regression. Receiver operating characteristic curves were used to compare the model to current ACNS models. There were a total of 56,466 drivers. Age, ejection, braking, avoidance, velocity, restraints, passenger-side impact, rollover, and vehicle weight and type were associated with injury (p < 0.05). The area under the receiver operating characteristic curve (83.9) was significantly greater than current ACNS models. We have developed a thoracoabdominal injury probability model that may improve patient triage when used with ACNS.

  7. Gas revenue increasingly significant

    Megill, R.E.


    This paper briefly describes the wellhead prices of natural gas compared to crude oil over the past 70 years. Although natural gas prices have never reached price parity with crude oil, the relative value of a gas BTU has been increasing. It is one of the reasons that the total amount of money coming from natural gas wells is becoming more significant. From 1920 to 1955 the revenue at the wellhead for natural gas was only about 10% of the money received by producers. Most of the money needed for exploration, development, and production came from crude oil. At present, however, over 40% of the money from the upstream portion of the petroleum industry is from natural gas. As a result, in a few short years natural gas may become 50% of the money revenues generated from wellhead production facilities

The structural equation modelling shows a more expressive impact of general factor (inductive and fluid factor associated to all BPR tests in academic achievement prediction, even tough its importance decreases progressively when we advance on school grades. At same time, specific components in each test are present in a second model namely for the 5th and 6th grades. From 9th to 12th grades the specific contributes of tests are confined to the verbal reasoning test (numerical reasoning test appears in 9th grade too. So we can conclude for the importance of g factor to explain the academic performance, but specific cognitive components can also contribute to reinforce the relation between intelligence and school achievement.

    Supe, S.J.; Nagalaxmi, K.V.; Meenakshi, L.


    In the practice of radiotherapy, various concepts like NSD, CRE, TDF, and BIR are being used to evaluate the biological effectiveness of the treatment schedules on the normal tissues. This has been accepted as the tolerance of the normal tissue is the limiting factor in the treatment of cancers. At present when various schedules are tried, attention is therefore paid to the biological damage of the normal tissues only and it is expected that the damage to the cancerous tissues would be extensive enough to control the cancer. Attempt is made in the present work to evaluate the concent of tumor significant dose (TSD) which will represent the damage to the cancerous tissue. Strandquist in the analysis of a large number of cases of squamous cell carcinoma found that for the 5 fraction/week treatment, the total dose required to bring about the same damage for the cancerous tissue is proportional to T/sup -0.22/, where T is the overall time over which the dose is delivered. Using this finding the TSD was defined as DxN/sup -p/xT/sup -q/, where D is the total dose, N the number of fractions, T the overall time p and q are the exponents to be suitably chosen. The values of p and q are adjusted such that p+q< or =0.24, and p varies from 0.0 to 0.24 and q varies from 0.0 to 0.22. Cases of cancer of cervix uteri treated between 1978 and 1980 in the V. N. Cancer Centre, Kuppuswamy Naidu Memorial Hospital, Coimbatore, India were analyzed on the basis of these formulations. These data, coupled with the clinical experience, were used for choice of a formula for the TSD. Further, the dose schedules used in the British Institute of Radiology fraction- ation studies were also used to propose that the tumor significant dose is represented by DxN/sup -0.18/xT/sup -0.06/

  11. Uranium chemistry: significant advances

    Mazzanti, M.


    The author reviews recent progress in uranium chemistry achieved in CEA laboratories. Like its neighbors in the Mendeleev chart uranium undergoes hydrolysis, oxidation and disproportionation reactions which make the chemistry of these species in water highly complex. The study of the chemistry of uranium in an anhydrous medium has led to correlate the structural and electronic differences observed in the interaction of uranium(III) and the lanthanides(III) with nitrogen or sulfur molecules and the effectiveness of these molecules in An(III)/Ln(III) separation via liquid-liquid extraction. Recent work on the redox reactivity of trivalent uranium U(III) in an organic medium with molecules such as water or an azide ion (N 3 - ) in stoichiometric quantities, led to extremely interesting uranium aggregates particular those involved in actinide migration in the environment or in aggregation problems in the fuel processing cycle. Another significant advance was the discovery of a compound containing the uranyl ion with a degree of oxidation (V) UO 2 + , obtained by oxidation of uranium(III). Recently chemists have succeeded in blocking the disproportionation reaction of uranyl(V) and in stabilizing polymetallic complexes of uranyl(V), opening the way to to a systematic study of the reactivity and the electronic and magnetic properties of uranyl(V) compounds.

    Full Text Available The concept of "public accountability" is a challenge for political science as a new concept in this area in full debate and developement ,both in theory and practice. This paper is a theoretical approach of displaying some definitions, relevant meanings and significance odf the concept in political science. The importance of this concept is that although originally it was used as a tool to improve effectiveness and eficiency of public governance, it has gradually become a purpose it itself. "Accountability" has become an image of good governance first in the United States of America then in the European Union.Nevertheless,the concept is vaguely defined and provides ambiguous images of good governance.This paper begins with the presentation of some general meanings of the concept as they emerge from specialized dictionaries and ancyclopaedies and continues with the meanings developed in political science. The concept of "public accontability" is rooted in economics and management literature,becoming increasingly relevant in today's political science both in theory and discourse as well as in practice in formulating and evaluating public policies. A first conclusin that emerges from, the analysis of the evolution of this term is that it requires a conceptual clarification in political science. A clear definition will then enable an appropriate model of proving the system of public accountability in formulating and assessing public policies, in order to implement a system of assessment and monitoring thereof.

    Jo A. Ziegler


    The purpose of this calculation is to identify radionuclides that are significant to offsite doses from potential preclosure events for spent nuclear fuel (SNF) and high-level radioactive waste expected to be received at the potential Monitored Geologic Repository (MGR). In this calculation, high-level radioactive waste is included in references to DOE SNF. A previous document, ''DOE SNF DBE Offsite Dose Calculations'' (CRWMS M&O 1999b), calculated the source terms and offsite doses for Department of Energy (DOE) and Naval SNF for use in design basis event analyses.

  20. Snacks, beverages, vending machines, and school stores: a comparison of alternative and regular schools in Minnesota, 2002 to 2008. (United States)

    Kubik, Martha Y; Davey, Cynthia; MacLehose, Richard F; Coombes, Brandon; Nanney, Marilyn S


    In US secondary schools, vending machines and school stores are a common source of low-nutrient, energy-dense snacks and beverages, including sugar-sweetened beverages, high-fat salty snacks, and candy. However, little is known about the prevalence of these food practices in alternative schools, which are educational settings for students at risk of academic failure due to truancy, school expulsion, and behavior problems. Nationwide, more than 5,000 alternative schools enroll about one-half million students who are disproportionately minority and low-income youth. Principal survey data from a cross-sectional sample of alternative (n=104) and regular (n=339) schools collected biennially from 2002-2008 as part of the Centers for Disease Control and Prevention Minnesota School Health Profiles were used to assess and compare food practice prevalence over time. Generalized estimating equation models were used to estimate prevalence, adjusting for school demographics. Over time, food practice prevalence decreased significantly for both alternative and regular schools, although declines were mostly modest. However, the decrease in high-fat, salty snacks was significantly less for alternative than regular schools (-22.9% vs -42.2%; Pvending machines and school stores in alternative schools than regular schools, which may contribute to increased snacking behavior among students and extra consumption of salt, fat, and sugar. Study findings support the need to include alternative schools in future efforts that aim to reform the school food environment. Copyright © 2015 Academy of Nutrition and Dietetics.

  1. The contribution of internal resources, external resources, and emotional distress to use of drugs and alcohol among Israeli Jewish urban adolescents. (United States)

    Lipschitz-Elhawi, Racheli; Itzhaky, Haya


    The contribution of selected background variables (age, gender), internal resources (mastery, emotional maturity), external resources (parental and peer support), and emotional distress to alcohol and drug use among 160 Israeli Jewish urban high school students were examined. Analyzing the variables with hierarchical regression, emotional distress contributed most significantly to both alcohol and drug use, and the contribution of age was somewhat less significant for both of them. Emotional distress also contributed indirectly to drug use through an interaction with one's sense of mastery. Gender, internal resources, and external resources contributed differentially to alcohol and drug use. Whereas gender and internal resources contributed only to drug use, external resources contributed only to alcohol use. Specifically, peer support contributed positively to alcohol use whereas parental support contributed negatively. The discussion provides explanations for these research findings and their implications, and the research's limitations are noted.

    Full Text Available Any psychological paradigm needs a psychopathological system that helps professionals to describe and explain the behavioral expressions that deviate from “normal” (whether this term is used with the semantic property of statistical or ideal adaptations. In this work, I seek to present the system that I have been developing since 1998 among the psychologists at the Instituto Vegotsky de Lisboa (Vygotsky Institute of Lisbon, Portugal, to understand psychopathology with regard to the vygotskian approach. It was conceived and designed according to the work of Rita Mendes Leal and her contribution to socioemotional development theory, AR Luria’s systemic and dynamic theory of the human brain, the theory of Activity (dyatel’nost of AN Leont’ev, and the psychopathological German school of E Kraepelin, presented and disseminated in Portugal in the early twentieth century by Professor Sobral Cid. It is intended to be a proposal to colleagues who are interested in postnonclassical psychology and a request for arguments.

  6. Junk Food in Schools and Childhood Obesity. (United States)

    Datar, Ashlesha; Nicosia, Nancy


    Despite limited empirical evidence, there is growing concern that junk food availability in schools has contributed to the childhood obesity epidemic. In this paper, we estimate the effects of junk food availability on BMI, obesity, and related outcomes among a national sample of fifth-graders. Unlike previous studies, we address the endogeneity of the school food environment by controlling for children's BMI at school entry and estimating instrumental variables regressions that leverage variation in the school's grade span. Our main finding is that junk food availability does not significantly increase BMI or obesity among this fifth grade cohort despite the increased likelihood of in-school junk food purchases. The results are robust to alternate measures of junk food availability including school administrator reports of sales during school hours, school administrator reports of competitive food outlets, and children's reports of junk food availability. Moreover, the absence of any effects on overall food consumption and physical activity further support the null findings for BMI and obesity.

  7. Availability of Automated External Defibrillators in Public High Schools. (United States)

    White, Michelle J; Loccoh, Emefah C; Goble, Monica M; Yu, Sunkyung; Duquette, Deb; Davis, Matthew M; Odetola, Folafoluwa O; Russell, Mark W


    To assess automated external defibrillator (AED) distribution and cardiac emergency preparedness in Michigan secondary schools and investigate for association with school sociodemographic characteristics. Surveys were sent via electronic mail to representatives from all public high schools in 30 randomly selected Michigan counties, stratified by population. Association of AED-related factors with school sociodemographic characteristics were evaluated using Wilcoxon rank sum test and χ(2) test, as appropriate. Of 188 schools, 133 (71%) responded to the survey and all had AEDs. Larger student population was associated with fewer AEDs per 100 students (P schools. Schools with >20% students from racial minority groups had significantly fewer AEDs available per 100 students than schools with less racial diversity (P = .03). Schools with more students eligible for free and reduced lunch were less likely to have a cardiac emergency response plan (P = .02) and demonstrated less frequent AED maintenance (P = .03). Although AEDs are available at public high schools across Michigan, the number of AEDs per student varies inversely with minority student population and school size. Unequal distribution of AEDs and lack of cardiac emergency preparedness may contribute to outcomes of sudden cardiac arrest among youth. Copyright © 2016 Elsevier Inc. All rights reserved.

  8. Schools and communities in Hungary (United States)

    Hunyady, Susan


    The democratic reform of public education in Hungary after the Second World War brought about a system which now includes Day-Care from the ages of 4-6 and compulsory Elementary School education up to the age of 16. A high proportion of students go on to Secondary education in vocational schools, special schools or grammar shools. The system is supplemented by career-counselling and provision for children with difficult home-backgrounds and for the mentally-retarded. District Councils are responsible for the schools in their areas and for the zoning that determines which schools children should attend. The environment of a school has a strong influence not only upon the standard of its facilities and the quality of its staff but also upon the function it is expected to fulfil in the community. Achievement is directly related to the degree of urbanization, but the increasing participation of farming-co-operatives in education in rural areas promises well for the development of better facilities and mutual understanding there. Housing estates in high-density residential areas make special demands which are being met in different ways. The role of the school in general is being expanded to include children's leisure time activities; at the same time factories are making a significant contribution locally through vocational guidance, financial help, and training-for-work programmes. Councils are implementing the requirements of public education resolutions to integrate school education into the whole scheme of public education, co-ordinating the activities of all social and cultural institutions, and developing new multi-functional complexes, to give a more effective and efficient service to the whole community.

  9. [Factors associated with adherence to school meals by adolescents in State public schools in Colombo, Paraná State, Brazil]. (United States)

    Valentim, Emanuele de Araujo; Almeida, Claudia Choma Bettega de; Taconeli, César Augusto; Osório, Mônica Maria; Schmidt, Suely Teresinha


    This study aimed to estimate the prevalence of adherence to school meals and associated factors among adolescent schoolchildren (N = 1,569). The adolescents completed an on-line questionnaire on adherence to school meals, and their parents answered another questionnaire on socioeconomic data. The chi-square test was used to assess the association between adherence to school meals and gender, nutritional status, per capita family income, maternal schooling, adolescents' opinions on the dining hall layout, whether they considered school meals healthy, and consumption of other foods. Variables with statistical significance for adherence to school meals were included in the multilevel proportional odds logistic regression model. The covariates for comprising the final model were defined by backward selection methods. The results of the adjusted model were presented as odds ratios with respective 95% confidence intervals (95%CI). Prevalence of adherence to school meals was low, especially effective adherence (19.8%). Adherence was associated with per capita family income less than one minimum wage, lower consumption of foods outside of school meals, the fact that adolescents considered the dining hall space adequate, and believing that school meals are healthy. Adherence to school meals in this study falls short of universal coverage for the program. Different factors contribute to incomplete program implementation, which may hinder achieving the food and nutritional security policy under the Brazilian National School Feeding Program (PNAE).

  11. Snacks, sweetened beverages, added sugars, and schools. (United States)


    Concern over childhood obesity has generated a decade-long reformation of school nutrition policies. Food is available in school in 3 venues: federally sponsored school meal programs; items sold in competition to school meals, such as a la carte, vending machines, and school stores; and foods available in myriad informal settings, including packed meals and snacks, bake sales, fundraisers, sports booster sales, in-class parties, or other school celebrations. High-energy, low-nutrient beverages, in particular, contribute substantial calories, but little nutrient content, to a student's diet. In 2004, the American Academy of Pediatrics recommended that sweetened drinks be replaced in school by water, white and flavored milks, or 100% fruit and vegetable beverages. Since then, school nutrition has undergone a significant transformation. Federal, state, and local regulations and policies, along with alternative products developed by industry, have helped decrease the availability of nutrient-poor foods and beverages in school. However, regular access to foods of high energy and low quality remains a school issue, much of it attributable to students, parents, and staff. Pediatricians, aligning with experts on child nutrition, are in a position to offer a perspective promoting nutrient-rich foods within calorie guidelines to improve those foods brought into or sold in schools. A positive emphasis on nutritional value, variety, appropriate portion, and encouragement for a steady improvement in quality will be a more effective approach for improving nutrition and health than simply advocating for the elimination of added sugars.

  12. Stress faced by gifted Vietnamese students: what might contribute to it?

    Directory of Open Access Journals (Sweden)

    Minh Hang Thi Nguyen


    Full Text Available Background Gifted students might have to face an abundance of stress. Nevertheless, very little evidence in Vietnam indicates how much stress those students are experiencing and what might predict it. This study aims to examine the stress level in students of the High School for Gifted Students in Hanoi and factors that might contribute to the stress. Participants and procedure This is a cross sectional study with the participation of 150 students from the High School for Gifted Students, Hanoi. Data were collected from March to April 2015. The first measure was the “Stress Level Test”, which was adapted to the Vietnamese culture to measure academic stress in students. The second measure examined factors contributing to stress: 1 social life, 2 family, 3 school work, 4 personal relationships, 5 well-being, 6 adapting skills. Results The results showed that 74% of students were experiencing mild to medium stress, which was found to be higher in girls and in students who lived away from home. The six predicting factors significantly contribute 17.30% to students’ stress experience, of which school work (p = .001 and students’ well-being (p = .011 can individually predict stress. These outcomes suggested that more attention should be focused on this specific population and more actions need to be taken to help them perform better at school. Conclusions Students of the High School for Gifted Students definitely experienced a considerable amount of stress which was related to school pressure and their well-being. For them to have a better high school life, more recreational and leisure time activities outside the classroom need to take place. In addition, more approachable and functional advisors and counseling personnel would be an ideal solution to this problem.

  13. Determining Semantically Related Significant Genes. (United States)

    Taha, Kamal


    GO relation embodies some aspects of existence dependency. If GO term xis existence-dependent on GO term y, the presence of y implies the presence of x. Therefore, the genes annotated with the function of the GO term y are usually functionally and semantically related to the genes annotated with the function of the GO term x. A large number of gene set enrichment analysis methods have been developed in recent years for analyzing gene sets enrichment. However, most of these methods overlook the structural dependencies between GO terms in GO graph by not considering the concept of existence dependency. We propose in this paper a biological search engine called RSGSearch that identifies enriched sets of genes annotated with different functions using the concept of existence dependency. We observe that GO term xcannot be existence-dependent on GO term y, if x- and y- have the same specificity (biological characteristics). After encoding into a numeric format the contributions of GO terms annotating target genes to the semantics of their lowest common ancestors (LCAs), RSGSearch uses microarray experiment to identify the most significant LCA that annotates the result genes. We evaluated RSGSearch experimentally and compared it with five gene set enrichment systems. Results showed marked improvement.

  14. The energetic significance of cooking. (United States)

    Carmody, Rachel N; Wrangham, Richard W


    While cooking has long been argued to improve the diet, the nature of the improvement has not been well defined. As a result, the evolutionary significance of cooking has variously been proposed as being substantial or relatively trivial. In this paper, we evaluate the hypothesis that an important and consistent effect of cooking food is a rise in its net energy value. The pathways by which cooking influences net energy value differ for starch, protein, and lipid, and we therefore consider plant and animal foods separately. Evidence of compromised physiological performance among individuals on raw diets supports the hypothesis that cooked diets tend to provide energy. Mechanisms contributing to energy being gained from cooking include increased digestibility of starch and protein, reduced costs of digestion for cooked versus raw meat, and reduced energetic costs of detoxification and defence against pathogens. If cooking consistently improves the energetic value of foods through such mechanisms, its evolutionary impact depends partly on the relative energetic benefits of non-thermal processing methods used prior to cooking. We suggest that if non-thermal processing methods such as pounding were used by Lower Palaeolithic Homo, they likely provided an important increase in energy gain over unprocessed raw diets. However, cooking has critical effects not easily achievable by non-thermal processing, including the relatively complete gelatinisation of starch, efficient denaturing of proteins, and killing of food borne pathogens. This means that however sophisticated the non-thermal processing methods were, cooking would have conferred incremental energetic benefits. While much remains to be discovered, we conclude that the adoption of cooking would have led to an important rise in energy availability. For this reason, we predict that cooking had substantial evolutionary significance.

  16. Volatile Organic Compounds: Characteristics, distribution and sources in urban schools (United States)

    Mishra, Nitika; Bartsch, Jennifer; Ayoko, Godwin A.; Salthammer, Tunga; Morawska, Lidia


    Long term exposure to organic pollutants, both inside and outside school buildings may affect children's health and influence their learning performance. Since children spend significant amount of time in school, air quality, especially in classrooms plays a key role in determining the health risks associated with exposure at schools. Within this context, the present study investigated the ambient concentrations of Volatile Organic Compounds (VOCs) in 25 primary schools in Brisbane with the aim to quantify the indoor and outdoor VOCs concentrations, identify VOCs sources and their contribution, and based on these; propose mitigation measures to reduce VOCs exposure in schools. One of the most important findings is the occurrence of indoor sources, indicated by the I/O ratio >1 in 19 schools. Principal Component Analysis with Varimax rotation was used to identify common sources of VOCs and source contribution was calculated using an Absolute Principal Component Scores technique. The result showed that outdoor 47% of VOCs were contributed by petrol vehicle exhaust but the overall cleaning products had the highest contribution of 41% indoors followed by air fresheners and art and craft activities. These findings point to the need for a range of basic precautions during the selection, use and storage of cleaning products and materials to reduce the risk from these sources.

    adolescence. The first symptoms are usually noticed in early childhood by teachers or caregivers. This study aimed to analyze the effects of collaborative consultation and planning proposal involving physiotherapy with classroom teachers and physical education teachers of two students with DMD, who presented severely limiting functional abilities; the objective was to improve their participation and comfort in the two most significant contexts of their daily lives: at school and at home. Visits to the two students' schools and to one of their homes were undertaken, in order to investigate their actual needs. Data was collected through interviews with the students, their parents, classroom teachers and physical education teachers. The strategies that were developed involved the adaptation of school furniture, acquisition of low tech materials and resources for the students' use and promotion of specialized orientations for the teachers involved and parents of the student with greater physical needs. It was possible to observe that the ecologic physiotherapy approach, aimed at environmental adaptations and collaborative planning of activities, provided some help and comfort for the participating students and enabled greater involvement/participation at school, besides contributing to the teachers' development. Furthermore, the adaptations of the students' homes and supervision of the parents were demonstrated to be essential measures as they provided some comfort and autonomy to the student with more severe limitations in the home environment.

  18. [School Entrance Examination for Lateral Entrants - What Can and What Should They be Able to Do? A Discussion Contribution Based on the Data from the Health Authority Frankfurt am Main 2006-2016]. (United States)

    Karathana, Maria; Krackhardt, Bernhard; Schade, Manuela; Heudorf, Ursel


    The medical investigation of school beginners is one of the essential tasks of the child and youth services of the health authorities. While in all federal states in Germany, the examination of all school beginners is legally clearly stipulated, the situation for "lateral entry", that is, children of school age, who are moving from a foreign country to a local German community and attending school there, is not clearly regulated in the respective school laws. This article presents the experiences of the lateral entry investigations in Frankfurt am Main. All children of school age who moved to Frankfurt from abroad undergo a health check. This encompasses a standardized questionnaire-based history with the help of interpreters, including a review of the available vaccination document (case history sheets are available in different languages), an eye examination, hearing test and a physical examination. Children over the age of 15 who came from countries with a high prevalence for tuberculosis had chest x-ray. Between 2006 and June 2016, a total of 8245 children and adolescents were examined, in 4% of the children abnormalities in hearing, and in 22% in visual screening showed noticeable problems, with an increasing trend in recent years. The vaccination status was unknown in two-thirds of the children, one quarter of the children were sufficiently vaccinated against tetanus, diphtheria, polio and pertussis, and 19.5% were immunized against measles (vaccine or disease). Diseases of the respiratory tract, the heart and the circulation were predominant with a total of 4%, followed by musculoskeletal disorders with 3%. Lice infestation was found in 1.7% of children. In 0,7% of 2171 children with chest-X-rays, a conspicuous pulmonary lesion was diagnosed, but no tuberculosis. The focus of the lateral entrance examination is a school-related health status. On the basis of experience gained in Frankfurt am Main, it should be pointed out that investigations by the lateral

  19. High orders of perturbation theory. Are renormalons significant?

    International Nuclear Information System (INIS)

    Suslov, I.M.


    According to Lipatov [Sov. Phys. JETP 45, 216 (1977)], the high orders of perturbation theory are determined by saddle-point configurations, i.e., instantons, which correspond to functional integrals. According to another opinion, the contributions of individual large diagrams, i.e., renormalons, which, according to t'Hooft [The Whys of Subnuclear Physics: Proceedings of the 1977 International School of Subnuclear Physics (Erice, Trapani, Sicily, 1977), A. Zichichi (Ed.), Plenum Press, New York (1979)], are not contained in the Lipatov contribution, are also significant. The history of the conception of renormalons is presented, and the arguments in favor of and against their existence are discussed. The analytic properties of the Borel transforms of functional integrals, Green's functions, vertex parts, and scaling functions are investigated in the case of φ 4 theory. Their analyticity in a complex plane with a cut from the first instanton singularity to infinity (the Le Guillou-Zinn-Justin hypothesis [Phys. Rev. Lett. 39, 95 (1977); Phys. Rev. B 21, 3976 (1980)] is proved. It rules out the existence of the renormalon singularities pointed out by t'Hooft and demonstrates the nonconstructiveness of the conception of renormalons as a whole. The results can be interpreted as an indication of the internal consistency of φ 4 theory

  10. Violence in the School Setting: A School Nurse Perspective. (United States)

    King, Kate K


    Violence in schools has become a significant public health risk and is not limited to violent acts committed in the school setting. Violence in homes, neighborhoods, and communities also affects the learning and behaviors of children while at school. School violence, such as shootings, weapons in schools, assaults, fights, bullying; other witnessed violence in non-school settings; and violence as a cultural norm of problem solving can all impact the ability of children to function in school. School nurses serve on the front-line of problem identification and intervene to diminish the effects of violence on both school children as individuals and on populations in schools and the community. This article describes ways in which school nurses deal with violence and concludes with discussion of potential responses to violence, including the school nurse response to violence and implications for other healthcare professionals.

    Pries-Heje, Jan; Baskerville, Richard


    This paper discusses and defines the achievement of significance in design science research. We review the values and processes of old-science and how this mode of science attacks the complexity of scientific knowledge production through analysis. We then explain how new-science attacks...... the complexity of scientific knowledge production through synthesis. The work argues that significance of the new-science contribution in design science can be obfuscated when wrapped in old-science. This understanding helps reveal how new-science, such as design science research, constitutes its significance...

  14. Teacher conceptions in the area of Nature Sciences about the construction of interdisciplinarity in Polytechnic Intermediate Education: the contribution of faculty expertise to reality in two schools in Northern Rio Grande do Sul

    Directory of Open Access Journals (Sweden)

    Bruna Carminatti


    Full Text Available High School education in Rio Grande do Sul underwent reformulations with the proposal for Polytechnic Intermediate Education suggested by the State Education Office. Overall, this proposal arose from the demand for improvements in elementary education, where High School education is concerned, and was implemented along the years of 2012, 2013 and 2014. Among the desired improvements was the need to overcome content education through interdisciplinarity and an integrated curriculum. Taking such changes into consideration – which implied the creation of knowledge areas, curricular restructuring, changes to the means of evaluation and the planning and teaching methodology presumptions – this article aims to report the path and results from research that proposed to investigate the manner in which interdisciplinarity began being constructed by educators in the area of Nature Sciences from faculty expertise. The methodology employed was of ethnographic research, that allowed to gather a wealth of data and opinions from the individuals investigated, namely nine teachers from the Nature Sciences area that encompasses the subjects of chemistry, physics and biology, from two intermediate education public schools in Northern Rio Grande do Sul. Data interpretation was carried out under the perspective of Discursive Textual Analysis and allowed for the identification of both the hurdles that made interdisciplinary construction and action unfeasible, such as lack of time for planning, and possible alternatives to overcome such hurdles, among which faculty expertise. From the discussion of those results, it can be observed that the proposal for Polytechnic High School provided space for the construction of the interdisciplinary praxis as well as for reflecting on and awareness building of its need, making it feasible from theoretic-methodological (reoptions on the part of the faculty in the bias of their expertise as such.

  15. Rewards: A predictor of well-being and service quality of school principals in the North-West province

    Kamohelo Nthebe


    Full Text Available Orientation: School principals have an important role to play in the quality of service delivery in schools. Evidence suggests that school principals are generally poorly compensated, which has an adverse impact on their well-being and subsequent service quality orientation. Research purpose: This study investigated whether rewards are a predictor of well-being and service orientation of school principals in the North-West province. Motivation for the study: Effective school principals are fundamental to the success of any school, which necessitates the establishment of an effective reward and remuneration system. Research design, approach and method: Quantitative research was carried out among school principals (N = 155 in four districts of the North-West province. The Total Rewards Scale, Maslach’s Burnout Inventory – General Survey, the Utrecht Work Engagement Scale and the SERVQUAL measure were administered among the principals. Main findings: The results showed that rewards are a significant predictor of the well-being and service quality of school principals. The results further showed that burnout significantly reduces the service quality of school principals. No significant relationships were found between work engagement and the service quality of school principals. Practical/managerial implications: An effective total rewards system enhances the well-being of school principals and, subsequently, their willingness and commitment to delivering quality services. Contribution: The results of this study point out some key elements that need to be considered by the Department of Education to enable quality service delivery in South African schools.

  16. School-Based Caries Prevention, Tooth Decay, and the Community Environment. (United States)

    Ruff, R R; Niederman, R


    The school and community context can contribute to inequity in child oral health. Whether the school and community affect the effectiveness of school-based caries prevention is unknown. The association between the school and community environment and dental caries, as well as their moderating effects with school-based caries prevention, was assessed using multilevel mixed-effects regression. Data were derived from a 6-y prospective cohort study of children participating in a school-based caries prevention program. For the school and community, living in a dental-shortage area and the proportion of children receiving free or reduced lunch were significantly related to an increased risk of dental caries at baseline. Caries prevention was associated with a significant per-visit decrease in the risk of untreated caries, but the rate of total caries experience increased over time. Caries prevention was more effective in children who had prior dental care at baseline and in schools with a higher proportion of low socioeconomic status students. There was significant variation across schools in the baseline prevalence of dental caries and the effect of prevention over time, although effects were modest. The school and community environment have a direct impact on oral health and moderate the association between school-based caries prevention and dental caries. Knowledge Transfer Statement: School-based caries prevention can be an effective means to reduce oral health inequity by embedding dental care within schools. However, the socioeconomic makeup of schools and characteristics of the surrounding community can affect the impact of school-based care.

  17. Chronic Student Absenteeism: The Critical Role of School Nurses. (United States)

    Jacobsen, Kathleen; Meeder, Linda; Voskuil, Vicki R


    Routine school attendance is necessary for youth to develop into well-educated, successful adult citizens who will make significant contributions to society. Yet over 5 million students in the United States are chronically absent missing more than 10% of school in a year. The growing problem of chronic absenteeism among youth can be linked to increases in chronic health conditions in childhood such as allergies, asthma, diabetes, and obesity. School nurses are in an ideal position to play a vital role in reducing chronic student absenteeism, enabling youth to achieve their maximum learning potential. However, the role of the school nurse has not historically been recognized as a key factor for assisting youth to be present and regularly engaged in school. This feature article highlights a hospital-funded school nurse program within the state of Michigan that has reduced chronic absenteeism rates by placing school nurses into schools where previously there were none. The program implemented a number of initiatives that were instrumental in increasing the health and safety of students and provides a unique "before and after" glimpse of how school nursing reduces chronic student absenteeism rates and validates the essential role of the nurse within the educational system. © 2016 The Author(s).

  18. Historical contributions from the Harvard system to adult spine surgery. (United States)

    Schoenfeld, Andrew J


    Literature review. To document the historical contributions from the Harvard Medical School system to the field of adult spine surgery. Despite the fact that significant contributions to the discipline of spinal surgery have derived from the Harvard system, no prior study documents the history of the Harvard spine services in a cohesive narrative. This historical perspective reviews the history of adult spine surgery within the Harvard system and outlines the significant contributions made by orthopedic and neurosurgical practitioners to the field. Literature reviews were performed from historical works, as well as scientific publications to fashion a cohesive review covering the history of spine surgery at Harvard from the early 19th century to the present. The development of the spine surgical services at the three main Harvard hospitals, and significant spine surgical personalities within the system, are discussed, including W. Jason Mixter, MD, Joseph S. Barr Sr., MD, and Marius N. Smith-Petersen, MD. Substantial developments that have arisen from the Harvard teaching hospitals include the recognition of disc herniation as the cause of radicular symptoms in the lower extremities, the description of lumbar discectomy as a surgical treatment for radicular pain, osteotomy for the correction of spinal deformity, and the first attempt to create a systematic algorithm capable of informing treatment for cervical spine trauma. Despite humble beginnings, the surgeons and scientists at Harvard have influenced nearly every facet of spine surgery over the course of the last two centuries.

    Full Text Available An experiment investigated the effect of a make-believe fantasy mode of problem presentation on reasoning about valid conditional syllogisms in three groups of 5-year-old children: a school children from middle-class families in England; b school children from middle-class families in Brazil; and, c children from low SES families in Brazil who had never gone to school. Previous investigations had reported that the use of a fantasy context elicited significantly more logically appropriate responses from school children than did other contexts, and that children with school experiences made significantly more logically appropriate responses than did children without school experience. The present investigation extended these findings to show that the beneficial effects of a fantasy context extended to lower-class illiterate children who never had been exposed to schooling

  4. Food Insecurity and Its Association With School Absenteeism Among Rural School Adolescents in Jimma Zone, Ethiopia. (United States)

    Tamiru, Dessalegn; Melaku, Yabsira; Belachew, Tefera


    Studies showed that poor health and nutrition among school adolescents are major barriers to educational access and achievements in low-income countries. This school-based study was aimed to assess the association of school absenteeism and food insecurity among rural school adolescents from grades 5 to 8 in Jimma zone, Ethiopia. Regression analyses were used to see the strength of association between dependent and independent variables using odds ratio and 95% confidence intervals. Multivariable logistic regression analysis was used to identify the predictor of school absenteeism. Validated tools are used to collect household food insecurity data. Results showed that school absenteeism is significantly high among adolescents from food insecure households when compared to adolescents from food secure households ( P absenteeism was negatively associated with male sex (adjusted odds ratio [AOR] = -0.91, 95% CI -1.85 to -0.03), household food security (adjusted odds ratio = -1.85, 95% CI -3.11 to -0.59), being an elder sibling (AOR = -0.37, 95% CI, -0.62 to -0.12), and mother involvement in decision making (AOR = -0.68, 95% CI, -1.33 to -0.03) while male-headed household was positively associated (AOR = 2.46, 95% CI, 1.37 to 4.56). Generally, this study showed that household food insecurity has significant contribution to school absenteeism among rural adolescents. Therefore, efforts should be made to improve household income earning capacity to reduce the prevalence of school absenteeism among rural school adolescents.

  5. An overview of juveniles and school violence. (United States)

    Murakami, Saori; Rappaport, Nancy; Penn, Joseph V


    Despite the relative rarity of school shootings, targeted violence, and school-associated violent deaths, any youth who presents with words, gestures, or actions of a threatening or violent nature in a school setting should be assessed and referred for further evaluation by a mental health professional and, if clinically indicated, a forensic evaluator.The request for a juvenile risk assessment for future dangerousness requires careful delineation of role and agency; confidentiality issues; a comprehensive diagnostic evaluation of the youth; and a detailed assessment of the youth's perceived threat or problematic behavior. Various protective and risk factors and consideration of other individual, family, school/peer, and situational factors should also be explored.There is still much information that is unknown when considering school violence or targeted school violence. There is clearly a need for additional research on the identification of at-risk youths, the contributions and significance of various protective and risk factors, the impact of peer relationships, and perceived rejection, socioeconomic status, subtypes of aggression, and developmental stages. Examples of future research direction might include difference by gender, presence of affective or psychotic disorders, substance abuse, emerging characterologic disturbances, and physiologic markers, such as cortisol or serotonin. Additional research regarding best practices and the development of clinical guidelines or practice parameters is also needed.

  6. Ergonomics Contribution in Maintainability (United States)

    Teymourian, Kiumars; Seneviratne, Dammika; Galar, Diego


    The objective of this paper is to describe an ergonomics contribution in maintainability. The economical designs, inputs and training helps to increase the maintainability indicators for industrial devices. This analysis can be helpful, among other cases, to compare systems, to achieve a better design regarding maintainability requirements, to improve this maintainability under specific industrial environment and to foresee maintainability problems due to eventual changes in a device operation conditions. With this purpose, this work first introduces the notion of ergonomics and human factors, maintainability and the implementation of assessment of human postures, including some important postures to perform maintenance activities. A simulation approach is used to identify the critical posture of the maintenance personnel and implements the defined postures with minimal loads on the personnel who use the equipment in a practical scenario. The simulation inputs are given to the designers to improve the workplace/equipment in order to high level of maintainability. Finally, the work concludes summarizing the more significant aspects and suggesting future research.

  7. The relationship between school type and academic performance at medical school: a national, multi-cohort study. (United States)

    Kumwenda, Ben; Cleland, Jennifer A; Walker, Kim; Lee, Amanda J; Greatrix, Rachel


    Differential attainment in school examinations is one of the barriers to increasing student diversity in medicine. However, studies on the predictive validity of prior academic achievement and educational performance at medical school are contradictory, possibly due to single-site studies or studies which focus only on early years' performance. To address these gaps, we examined the relationship between sociodemographic factors, including school type and average educational performance throughout medical school across a large number of diverse medical programmes. This retrospective study analysed data from students who graduated from 33 UK medical schools between 2012 and 2013. We included candidates' demographics, pre-entry grades (adjusted Universities and Colleges Admissions Service tariff scores) preadmission test scores (UK Clinical Aptitude Test (UKCAT) and Graduate Medical School Admissions Test (GAMSAT)) and used the UK Foundation Programme's educational performance measure (EPM) decile as an outcome measure. Logistic regression was used to assess the independent relationship between students' background characteristics and EPM ranking. Students from independent schools had significantly higher mean UKCAT scores (2535.1, SD=209.6) than students from state-funded schools (2506.1, SD=224.0, pschools came into medical school with significantly higher mean GAMSAT scores (63.9, SD=6.9) than students from state-funded schools (60.8, SD=7.1, pschools were almost twice as likely (OR=2.01, 95% CI 1.49 to 2.73) to finish in the highest rank of the EPM ranking than those who attended independent schools. This is the first large-scale study to examine directly the relationship between school type and overall performance at medical school. Our findings provide modest supportive evidence that, when students from independent and state schools enter with similar pre-entry grades, once in medical school, students from state-funded schools are likely to outperform students

  8. Impact significance determination-Pushing the boundaries

    International Nuclear Information System (INIS)

    Lawrence, David P.


    Impact significance determination practice tends to be highly variable. Too often insufficient consideration is given to good practice insights. Also, impact significance determinations are frequently narrowly defined addressing, for example, only individual, negative impacts, focusing on bio-physical impacts, and not seeking to integrate either the Precautionary Principle or sustainability. This article seeks to extend the boundaries of impact significance determination practice by providing an overview of good general impact significance practices, together with stakeholder roles and potential methods for addressing significance determination challenges. Relevant thresholds, criteria, contextual considerations and support methods are also highlighted. The analysis is then extended to address how impact significance determination practices change for positive as compared with negative impacts, for cumulative as compared with individual impacts, for socio-economic as compared with bio-physical impacts, when the Precautionary Principle is integrated into the process, and when sustainability contributions drive the EIA process and related impact significance determinations. These refinements can assist EIA practitioners in ensuring that the scope and nature of impact significance determinations reflect the broadened scope of emerging EIA requirements and practices. Suggestions are included for further refining and testing of the proposed changes to impact significance determination practice

  12. Charter Schools and Student Compositions of Traditional Public Schools

    Directory of Open Access Journals (Sweden)

    Nevbahar Ertas


    Full Text Available One of the most contentious urban education policy issues in the United States today is the expansion of charter schools and its repercussions. Does the expansion of charter schools affect the racial and socioeconomic composition of traditional public schools in the United States? This study provides empirical evidence on this question by relying on a panel design that uses school-level data from two states that have experimented with charter schools for more than 15 years: Ohio and Texas. Using county-level, spatial, and enrollment-based measures of charter exposure, the changes from pre- to post-charter-legislation stages in the student compositions of public schools that do and do not face competition from charters are examined. The results suggest that charter school presence contributes to aggregate-level changes in the share of non-Hispanic White and free-lunch-eligible students in traditional public schools in both states in different ways.

    Full Text Available Measuring school well-being in elementary school student is important. The experience of students at school will affect their perception, motivation and hope for their academic life in the future. We used Tripartite School Well-Being Model, based on the interaction among three aspects, namely school satisfaction, positive affect and negative affect. The aim of the study is to identify factors predicting the emergence of student’s positive affect and negative affect in elementary school. A total of 118 elementary school students of Class 6 in Bandung took a part in this study as respondent. The variables in this study were measured using three questionnaires: School Satisfaction, Positive Affect Student at School, and Negative Affect Student at School. Descriptive and inferential statistics through regression analysis was conducted to test the hypothesis. The results show that peer relationship, teacher-student relationship, and academic learning significantly contribute to build the positive affect of the student. Whereas, only the peer relationship predicted the negative affect of the student. This finding brings some practical implication for the educational process. The integrated multidimensional program which involves teacher, parents, peers, and student is crucial to promote student well-being at school.

It provides information about education in alternative schools: Montessori, Waldorf and the Integrated Thematic Instruction (ITI, where the research was realised. The Torrance test (TTCT and Urban test (TSD-Z were used for the identification of pupils’ creativity. The procreative tendency of the teachers was examined by the Self-Rating Scale of the Creatively Oriented Personality (SRSCP. The comparison of pupils’ and teachers’ results from standard and alternative schools brought diverse results. Our findings regarding the creativity level of pupils attending the second grade of Montessori and Waldorf schools (N=50 in comparison with the children in standard schools suggest no significant differences. The pupils of the alternative classes of ITI (N= 206 achieved significantly higher scores of originality than those of standard schools (N=194. A link between the teachers’ creative orientation and their pupils’ creativity has not been found.

  20. School farming for school feeding: experiences from Nakuru, Kenya

    Directory of Open Access Journals (Sweden)

    Dick Foeken


    Full Text Available School feeding is an important development tool and is related to at least three Millennium Development Goals. School farming has been largely overlooked in the urban agriculture literature but with many parents nowadays unable to afford school lunches for their children, it can play a vital role in reducing the costs involved in providing nutritional meals for pupils. This paper examines school farming in an urban setting, namely Nakuru town, Kenya and looks at the current practice, the extent to which school farming contributes to school feeding programs, and the challenges it faces and how these can be overcome. Based on a survey done in almost all primary and secondary schools in Nakuru, it shows that school farming and school feeding are now common practice in the town and that in many cases school farming does indeed contribute to school feeding programs. However, much more is possible and the paper indicates how various constraints in terms of land, water, support and leadership might be overcome.

  1. Cigarette price variation around high schools: evidence from Washington DC. (United States)

    Cantrell, Jennifer; Ganz, Ollie; Anesetti-Rothermel, Andrew; Harrell, Paul; Kreslake, Jennifer M; Xiao, Haijun; Pearson, Jennifer L; Vallone, Donna; Kirchner, Thomas R


    This study examines lowest cigarette prices in all tobacco retail outlets in Washington D.C. (n=750) in relation to the type and number of high schools nearby, controlling for confounders. The lowest overall and Newport menthol prices were significantly lower at outlets near public non-charter and charter schools compared with outlets near private schools. Given higher smoking prevalence and more price-sensitive youth subgroups in U.S. public schools, exposure to low prices may contribute to tobacco-related health disparities in minority and low-income populations. Tobacco taxes combined with policies to minimize the increasing use of price as a marketing tool are critical. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Objective: To study the characteristics of the epileptics and the risk factors contributing to the development of epilepsy. Results: Majority of the subjects were single (77.84%), 1st born among their siblings (25.95%), belonged to low social class (50.63%), and unemployed(25.31%). The major risk factors were family history of illness (23.52%) and positive medical problem around birth (12.66%). The presence of family history of illness, positive medical problem around birth and advanced maternal age at birth were associated with early onset of epilepsy. Vulnerability for the epilepsy also increases among hospital deliveries. Conclusion: Although the present study has identified various risk factors, yet the results need to be further confirmed through case-control studies. (author)

    Full Text Available Nowodworski Schools, whose current institutionalized continuator is Bartłomiej Nowodworski High School, have a legacy of a long history. The idea to found private schools was initially brought forward by the authorities and professors of the Cracovian University in 1586. The project was finally launched in 1588 mainly due to energetic steps taken by the subsequent chancellor of the Cracovian University doctor of medicine – Stanisław Pik Zawadzki. Over the first decades of its existence the schools faced numerous hardship. The institution was underfunded and both professors and students were exposed to epidemics so frequent in those times, such as for instance the plague in September 1588. Some conservative professors of the University also called for closing the academic colonies. Despite all the predicaments, the institution managed to survive. The most important benefactor for private schools in those difficult years was a Cracovian bishop Piotr Tylicki (in office: 1607–1616, who with the consent of the local chapter, donated PLN 10 000 to fund a separate professor department where the professors were obliged to give a one hour daily lecture in The Upper College as well as 2 hour classes in pronunciation and stylistic in private schools. The situation, however, did not improved significantly. In those times of crisis of private schooling there appeared the foundations of the Knight of the Maltese Order – Barłomiej Nowodworski. Nowodworski was a benefactor for numerous institutions, however, his most famous charity was his foundations for Nowodworski Schools. He donated PLN 8000 in 1612, 1617 and PLN 7000 in 1619 making it possible for those private schools to survive the difficult times. Nowodworski Schools had many benefactors, however, besides the foundation of B. Nowodworski the most prominent benefactors were Gabriel Prewancjusz Władysławski. He donated PLN 50 000. Thanks to his efforts and with the contribution from the King

    Verlaeken, J.


    The operating experience feedback system of VINCOTTE, called ARIANE, consists, among others, of preparing synthesis reports on specific safety concerns. A recent report deals with significant events caused by extranous acts. Events attributable to human error are numerous. Confusion errors have already been analysed in several publications (NES IRS 664 etc.). However, are described here some ten incidents where extranous acts occurred: ZION 2 (September 76), OYSTER CREEK (May 79), PALISADES (January 81), CATAWBA (August 85), etc. The contributing factors for these unfortunate initiatives are explained; several resort to psychological influences. Corrective actions are discussed, and some general lessons are drawn. (author)

  11. Significant Lactic Acidosis from Albuterol

    Directory of Open Access Journals (Sweden)

    Deborah Diercks


    Full Text Available Lactic acidosis is a clinical entity that demands rapid assessment and treatment to prevent significant morbidity and mortality. With increased lactate use across many clinical scenarios, lactate values themselves cannot be interpreted apart from their appropriate clinical picture. The significance of Type B lactic acidosis is likely understated in the emergency department (ED. Given the mortality that sepsis confers, a serum lactate is an important screening study. That said, it is with extreme caution that we should interpret and react to the resultant elevated value. We report a patient with a significant lactic acidosis. Though he had a high lactate value, he did not require aggressive resuscitation. A different classification scheme for lactic acidosis that focuses on the bifurcation of the “dangerous” and “not dangerous” causes of lactic acidosis may be of benefit. In addition, this case is demonstrative of the potential overuse of lactates in the ED.

    Full Text Available Sr. Editor En los hallazgos de Alarcón y Bárrig (2015 recientemente aparecidos, se encuentran resultados que esencialmente parecen replicar lo reportado en estudios anteriores sobre el tema. Esto añade evidencia acumulativa sobre las tendencias conductuales de las diferencias entre varones y mujeres respecto de los problemas de conducta, luego de más de una década en que se presentaron hallazgos similares en la población peruana (Majluf, 1999. No obstante, la presentación de sus resultados oscurece un tipo de información más útil, pues las autoras han priorizado únicamente el marco de la significancia estadística en la interpretación de sus análisis y en la sustentación de sus conclusiones. No se ha añadido algún comentario sobre la magnitud de las diferencias o lo que también se denomina significancia práctica. Actualmente, el reporte de la significancia práctica tiene un lugar obligado, y no solo recomendado, por el Manual de publicaciones de la American Psychological Association (APA, 2010, lo que ha impulsado que sea un componente sine qua non de los manuscritos sometidos a revistas científicas para su eventual publicación, sea para estudios cualitativos (p. ej., Duran et al., 2006 como cuantitativos (Coe y Merino, 2003; Merino, 2011.

  14. Minute Impurities Contribute Significantly to Olfactory Receptor Ligand Studies: Tales from Testing the Vibration Theory


    Paoli, M.; M?nch, D.; Haase, A.; Skoulakis, E.; Turin, L.; Galizia, C. G.


    Several studies have attempted to test the vibrational hypothesis of odorant receptor activation in behavioral and physiological studies using deuterated compounds as odorants. The results have been mixed. Here, we attempted to test how deuterated compounds activate odorant receptors using calcium imaging of the fruit fly antennal lobe. We found specific activation of one area of the antennal lobe corresponding to inputs from a specific receptor. However, upon more detailed analysis, we disco...

  15. Minute Impurities Contribute Significantly to Olfactory Receptor Ligand Studies: Tales from Testing the Vibration Theory. (United States)

    Paoli, M; Münch, D; Haase, A; Skoulakis, E; Turin, L; Galizia, C G


    Several studies have attempted to test the vibrational hypothesis of odorant receptor activation in behavioral and physiological studies using deuterated compounds as odorants. The results have been mixed. Here, we attempted to test how deuterated compounds activate odorant receptors using calcium imaging of the fruit fly antennal lobe. We found specific activation of one area of the antennal lobe corresponding to inputs from a specific receptor. However, upon more detailed analysis, we discovered that an impurity of 0.0006% ethyl acetate in a chemical sample of benzaldehyde-d 5 was entirely responsible for a sizable odorant-evoked response in Drosophila melanogaster olfactory receptor cells expressing dOr42b. Without gas chromatographic purification within the experimental setup, this impurity would have created a difference in the responses of deuterated and nondeuterated benzaldehyde, suggesting that dOr42b be a vibration sensitive receptor, which we show here not to be the case. Our results point to a broad problem in the literature on use of non-GC-pure compounds to test receptor selectivity, and we suggest how the limitations can be overcome in future studies.

  16. Clathrin-independent pathways do not contribute significantly to endocytic flux. (United States)

    Bitsikas, Vassilis; Corrêa, Ivan R; Nichols, Benjamin J


    Several different endocytic pathways have been proposed to function in mammalian cells. Clathrin-coated pits are well defined, but the identity, mechanism and function of alternative pathways have been controversial. Here we apply universal chemical labelling of plasma membrane proteins to define all primary endocytic vesicles, and labelling of specific proteins with a reducible SNAP-tag substrate. These approaches provide high temporal resolution and stringent discrimination between surface-connected and intracellular membranes. We find that at least 95% of the earliest detectable endocytic vesicles arise from clathrin-coated pits. GPI-anchored proteins, candidate cargoes for alternate pathways, are also found to enter the cell predominantly via coated pits. Experiments employing a mutated clathrin adaptor reveal distinct mechanisms for sorting into coated pits, and thereby explain differential effects on the uptake of transferrin and GPI-anchored proteins. These data call for a revision of models for the activity and diversity of endocytic pathways in mammalian cells.

Such thoughts aim to discuss how this teaching enters school education in the context of neoliberalism. Assuming that the emptiness in Geography teaching in school education is a result of Brazilian educational policies in neoliberalism, we intend to characterize the impairment of the critical perspective on this area of knowledge and present some contributions of historical critical pedagogy to face and overcome the current order. Besides, we seek to highlight the required knowledge to achieve an education that contributes to build a different society.

  1. Understanding mass school shootings: links between personhood and power in the competitive school environment. (United States)

    Thompson, Stephen; Kyle, Ken


    This paper explores perspectives about certain individual and social characteristics that may contribute to school shootings by students. It begins with perspectives on individual/environment fit, arguing first that persons marginalized by their caregivers during their upbringing, and by their peers, are lacking in the social interactions that help develop ethical behavior. Our argument contends that lacking such interactions may result in the failure to develop a sound moral philosophy. Further, we argue that when such persons enter the highly competitive environment found in some suburban and rural schools, some will be continually and consistently marginalized, finding their means of self-expression and sense of significance subdued. Their need for self-expression and a sense of significance as persons will surface, but without the benefit of a moral philosophy to guide that expression, this may result in deviant means of expression, such as violence--even extraordinary violence. We do not attempt to identify a list of specific traits of school shooters, which might lead to the development of a profile of school shooters. Rather, we are concerned with the characteristics of the environment in which shootings might occur, and how students not fully prepared for that environment might react. Thus, this paper is an overview of how seeds of the neglect of the basic needs of personhood, when sown early in life, and nurtured by peers, might come to fruition in the fertile field of the competitive school environment.

  4. Organization of Physical Activities as a Precondition of Quality Development of Motor Abilities of Pre-School and School Children

    Directory of Open Access Journals (Sweden)

    Marković Živorad


    Full Text Available In their work authors consider the significance of the organization of physical activities for the development of abilities of pre-school and school children. Led by theoretical basis that physical development of children represents the basis of their whole development, and that “fine motor skills” are determined by the development of its large motorics, the authors point to the significance of the content and structure of physical education programme in preschool institutions and younger age school classes. It is evident that the effects of cultivating of children development during preschool period can be seen in younger primary school classes. The goal of this research was to determine if and how much the different organization of preparatory part of physical education lesson for younger school children, determines the differences in the development of their motor abilities. By the use of experimental method, the effects of prolonged preparatory part of a lesson in younger school classes. This part was realized through complex of exercises which were supposed to have influence on transformation of motor abilities in relation to the structure with standard duration of certain parts of a lesson. It is determined that certain increase in body movement of students during physical activity can significantly contribute to better development of motor abilities. These abilities determine correct physical development and strengthening of health, which determines general aim of physical education.

    association between the number of detected aerosol particles and the school bus traffic intensity. Analysis of the filter samples collected at the school site between 6:00 and 9:00 AM revealed higher concentrations of elemental carbon as compared to the control site (2.8 +/- 0.9 times in March and 3.1 +/- 1.1 times in May). The data collected in this case study suggest that school buses significantly contribute to exposure of children to aerosol pollutants (including diesel exhaust particles) in the school vicinity.

    Background Bullying is a worldwide problem with varying consequences. Victims of school bullying may be targeted for many reasons including their appearance. They may also fear school and have difficulties in concentration. Objective This study aimed to determine the prevalence of bullying amongst adolescents in Kano, Northern Nigeria, the contribution of physical features and the perceived effect of bullying on their academic performance and school attendance. Subjects and methods Eight hundred and thirty-five students aged between 12 years and 17 years from eight randomly selected secondary schools in Kano, Nigeria took part in this study. Data collection was by self-administered questionnaires and analysis was by SPSS version 17. Results The pupils' mean age and standard deviation was 14.79 + 1.53 years. There were more male and private school pupils with 55.1% and 62%, respectively. About 43% of respondents reported being victims of bullying while about 32% had bullied someone else. There was more bullying in public schools than in private schools (p-value = 0.003). However, there was no significant gender difference (p > 0.05). More bullied pupils hated being in or outside the classroom (p bullied pupils played truant than non-bullied (p bullying felt it had consequences on their academic performance. Bullies frequently targeted general physical and dento-facial appearance. Conclusion The prevalence of bullying was high among the sampled population especially within public schools. This also had a significant negative effect on the students' academic performance.

  9. Respiratory neuroplasticity - Overview, significance and future directions. (United States)

    Fuller, David D; Mitchell, Gordon S


    Neuroplasticity is an important property of the neural system controlling breathing. However, our appreciation for its importance is still relatively new, and we have much to learn concerning different forms of plasticity, their underlying mechanisms, and their biological and clinical significance. In this brief review, we discuss several well-studied models of respiratory plasticity, including plasticity initiated by inactivity in the respiratory system, intermittent and sustained hypoxia, and traumatic injury to the spinal cord. Other aspects of respiratory plasticity are considered in other contributions to this special edition of Experimental Neurology on respiratory plasticity. Finally, we conclude with discussions concerning the biological and clinical significance of respiratory motor plasticity, and areas in need of future research effort. Copyright © 2016.

The study involved the implementation of the didactic component to promote recognition of their biological significance in elementary school students. Among the findings two species of nocturnal birds of prey were identified: common currucutú owl (Tropical Screech Owl, Megascops choliba and the barn owl (Tyto alba, with a relative abundance of 12 individuals and 10 individuals, respectively. It also includes changes in perception from students regarding beliefs and superstitions about such species, which favors the recognition of the biological role in the ecosystem and the need for its conservation.

  14. Effects of peer victimization in schools and perceived social support on adolescent well-being. (United States)

    Rigby, K


    It has been suggested that the mental health of schoolchildren can be undermined by repeated bullying at school and further exacerbated by having inadequate social support. To evaluate this claim, the General Health Questionnaire (GHQ) was administered anonymously to 845 adolescent schoolchildren attending coeducational secondary schools in South Australia, together with measures of the extent to which each reported being bullied at school and the social support available to them. Multiple regression analyses indicated that for both sexes frequent peer victimization and low social support contributed significantly and independently to relatively poor mental health.

  16. Examining school-based hygiene facilities: a quantitative assessment in a Ghanaian municipality. (United States)

    Appiah-Brempong, Emmanuel; Harris, Muriel J; Newton, Samuel; Gulis, Gabriel


    The crucial role of adequate water, sanitation and hygiene (WASH) facilities in influencing children's handwashing behaviour is widely reported. Report from UNICEF indicates a dearth of adequate data on WASH facilities in schools, especially in the developing world. This study sought to contribute to building the evidence-base on school hygiene facilities in Ghana. The study further explored for possible associations and differences between key variables within the context of school water, sanitation and hygiene. Data was collected from 37 junior high schools using an observational checklist. Methods of data analysis included a Scalogram model, Fisher's exact test, and a Student's t-test. Results of the study showed a facility deficiency in many schools: 33% of schools had students washing their hands in a shared receptacle (bowl), 24% had students using a single cotton towel to dry hands after handwashing, and only 16% of schools had a functional water facility. Furthermore, results of a proportion test indicated that 83% of schools which had functional water facilities also had functional handwashing stations. On the other hand, only 3% of schools which had functional water facilities also had a functional handwashing stations. A test of difference in the proportions of the two sets of schools showed a statistically significant difference (p facilities would be timely.

  17. How Occupational Health can contribute in a disaster and what we should prepare for the future--lessons learned through support activities of a medical school at the Fukushima Daiichi Nuclear Power Plant in Summer 2011. (United States)

    Mori, Koji; Tateishi, Seiichiro; Hiraoka, Koh; Kubo, Toshihiko; Okazaki, Ryuji; Suzuki, Katsunori; Kobayashi, Yuichi; Kohno, Kimitoshi


    A nuclear accident occurred at the Fukushima Daiichi Nuclear Power Plant of Tokyo Electric Power Company (TEPCO) as a result of a mega-earthquake and tsunami in March, 2011. A large number of workers were engaged in response and recovery operations under a complex structure of involved companies. They were exposed not only to radiation but also to other health hazards. TEPCO implemented programs to prevent radiation exposure, but had no effective systems for managing the other health risks and few occupational health (OH) professionals contributed to the health risk management. The University of Occupational and Environmental Health (UOEH), Japan, dispatched physicians to a quake-proof building at the plant to provide first-aid services from mid-May, 2011, and took a strategic approach to protecting workers from existing health risks. UOEH presented recommendations on OH systems and preventive measures against heat stress to the Government and TEPCO. The Ministry of Health, Labour, and Welfare issued guidelines to TEPCO and contractors. TEPCO implemented a comprehensive program against heat stress according to the guidelines and in cooperation with UOEH. As a result, we successfully prevented severe heat illness during summer 2011. From our experiences, we believe that the following recommendations should be considered: (1) the role of OH and the participation of experts should be defined in emergency response plans; (2) regulations should allow the national government and main companies involved to lead safety and health initiatives for all workers at disaster sites; and (3) OH professionals, response manuals and drills should be organized at a national level.

  3. How do different components of Effortful Control contribute to children's mathematics achievement? (United States)

    Sánchez-Pérez, Noelia; Fuentes, Luis J; Pina, Violeta; López-López, Jose A; González-Salinas, Carmen


    This work sought to investigate the specific contribution of two different components of Effortful Control (EC) -attentional focusing (AF) and inhibitory control- to children's mathematics achievement. The sample was composed of 142 children aged 9-12 year-old. EC components were measured through the Temperament in Middle Childhood Questionnaire (TMCQ; parent's report); math achievement was measured via teacher's report and through the standard Woodcock-Johnson test. Additionally, the contribution of other cognitive and socio-emotional processes was taken into account. Our results showed that only AF significantly contributed to the variance of children's mathematics achievement; interestingly, mediational models showed that the relationship between effortful attentional self-regulation and mathematics achievement was mediated by academic peer popularity, as well as by intelligence and study skills. Results are discussed in the light of the current theories on the role of children's self-regulation abilities in the context of school.

  19. Clinical significance of neonatal menstruation. (United States)

    Brosens, Ivo; Benagiano, Giuseppe


    Past studies have clearly shown the existence of a spectrum of endometrial progesterone responses in neonatal endometrium, varying from proliferation to full decidualization with menstrual-like shedding. The bleedings represent, similar to what occurs in adult menstruation, a progesterone withdrawal bleeding. Today, the bleeding is completely neglected and considered an uneventful episode of no clinical significance. Yet clinical studies have linked the risk of bleeding to a series of events indicating fetal distress. The potential link between the progesterone response and major adolescent disorders requires to be investigated by prospective studies. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

  11. Spatial and temporal variations in traffic-related particulate matter at New York City high schools (United States)

    Patel, Molini M.; Chillrud, Steven N.; Correa, Juan C.; Feinberg, Marian; Hazi, Yair; Deepti, K. C.; Prakash, Swati; Ross, James M.; Levy, Diane; Kinney, Patrick L.

    Relatively little is known about exposures to traffic-related particulate matter at schools located in dense urban areas. The purpose of this study was to examine the influences of diesel traffic proximity and intensity on ambient concentrations of fine particulate matter (PM 2.5) and black carbon (BC), an indicator of diesel exhaust particles, at New York City (NYC) high schools. Outdoor PM 2.5 and BC were monitored continuously for 4-6 weeks at each of 3 NYC schools and 1 suburban school located 40 km upwind of the city. Traffic count data were obtained using an automated traffic counter or video camera. BC concentrations were 2-3 fold higher at urban schools compared with the suburban school, and among the 3 urban schools, BC concentrations were higher at schools located adjacent to highways. PM 2.5 concentrations were significantly higher at urban schools than at the suburban school, but concentrations did not vary significantly among urban schools. Both hourly average counts of trucks and buses and meteorological factors such as wind direction, wind speed, and humidity were significantly associated with hourly average ambient BC and PM 2.5 concentrations in multivariate regression models. An increase of 443 trucks/buses per hour was associated with a 0.62 μg/m 3 increase in hourly average BC at an NYC school located adjacent to a major interstate highway. Car traffic counts were not associated with BC. The results suggest that local diesel vehicle traffic may be important sources of airborne fine particles in dense urban areas and consequently may contribute to local variations in PM 2.5 concentrations. In urban areas with higher levels of diesel traffic, local, neighborhood-scale monitoring of pollutants such as BC, which compared to PM 2.5, is a more specific indicator of diesel exhaust particles, may more accurately represent population exposures.

  12. School climate and delinquency among Chinese adolescents: analyses of effortful control as a moderator and deviant peer affiliation as a mediator. (United States)

    Bao, Zhenzhou; Li, Dongping; Zhang, Wei; Wang, Yanhui


    School climate is the quality and character of school life and reflects the norms, goals, values, interpersonal relationships, teaching and learning practices, and the organizational structure of a school. There is substantial literature documenting the negative association between positive school climate and adolescent delinquency, but little is known about the moderating and mediating mechanisms underlying this relationship. The aim of this study was to examine whether the direct and indirect pathways between school climate and adolescent delinquency would be moderated by effortful control. A sample of 2,758 Chinese adolescents (M age = 13.53 years, SD = 1.06) from 10 middle schools completed anonymous questionnaires regarding school climate, effortful control, deviant peer affiliation, and delinquency. After gender, age, geographical area, and socioeconomic status were included as covariates, the results revealed that school climate was significantly associated with adolescent delinquent behavior. This direct association was moderated by effortful control, such that the negative relationship between positive school climate and delinquency was only significant among adolescents low in effortful control. Moreover, the indirect association between school climate and delinquency via deviant peer affiliation was also moderated by effortful control. Specifically, the moderating effect of effortful control was not only manifested in the relationship between school climate and deviant peer affiliation, but also in the relationship between deviant peer affiliation and delinquency. These findings contribute to understanding the mechanisms through which positive school climate might reduce delinquent behavior and have important implications for prevention efforts aimed at diminishing adolescent delinquency.

  13. Moral significance of phenomenal consciousness. (United States)

    Levy, Neil; Savulescu, Julian


    Recent work in neuroimaging suggests that some patients diagnosed as being in the persistent vegetative state are actually conscious. In this paper, we critically examine this new evidence. We argue that though it remains open to alternative interpretations, it strongly suggests the presence of consciousness in some patients. However, we argue that its ethical significance is less than many people seem to think. There are several different kinds of consciousness, and though all kinds of consciousness have some ethical significance, different kinds underwrite different kinds of moral value. Demonstrating that patients have phenomenal consciousness--conscious states with some kind of qualitative feel to them--shows that they are moral patients, whose welfare must be taken into consideration. But only if they are subjects of a sophisticated kind of access consciousness--where access consciousness entails global availability of information to cognitive systems--are they persons, in the technical sense of the word employed by philosophers. In this sense, being a person is having the full moral status of ordinary human beings. We call for further research which might settle whether patients who manifest signs of consciousness possess the sophisticated kind of access consciousness required for personhood.

    Full text: Introduction: There is variable number of sesamoid bones in the human body; one of them is fabella, located in the tendon of the gastrocnemius muscle. Aim of this study was to investigate the frequency of occurrence of fabella in the Macedonian population and to discuss about clinical importance of this bone. Materials and methods: We retrospectively examined radiographs of 53 patients who had knee exams undertaken for a variety of clinical reasons, performed as a part of their medical treatment. Over a time span of six months, 53 patients (38 males and 15 females, age range 19-60 years, mean age of 36.7±12.3 years) were examined. Results: In seven (13.2%) patients of 53 analyzed reports, fabella was found in the lateral tendon of gastrocnemius muscle. We did not find a significant gender or side difference in the appearance of fabella. Conclusion: Although anatomic studies emphasized a lack of significance of the fabella, this bone has been associated with a spectrum of pathology affecting the knee as fabellar syndrome, perineal nerve injury and fracture. We should think of this sesamoid bone while performing diagnostic and surgical procedures

  16. Sex differences and violence among primary school students

    Directory of Open Access Journals (Sweden)

    Marković Živorad M.


    Full Text Available This is the micro research which studied the connection between gender and violence between older primary school students with the goal of discovering exposure of gender members to violence in school context and the ways of reaction to the violence. The researchers from different scientific disciplines have been permanently involved in studying the problem of violence for more than a decade with the goal to lessen the high percentage of violence in schools. In this sense, this research, with its range and character, represents the contribution in discovering characteristics of violence in schools in one specific local area, which could fill in the wholeness of this phenomenon. The research involved students of the final grade of primary school on the territory of the municipality of Svilajnac (which is in central part of Serbia and it was performed in December 2015. 236 students were surveyed. The survey consisted of the following questions a which questioned the social matrix of families in which the students live b which questioned presence and frequency of different types of violence between students in primary schools c which questioned the attitudes of students of both genders about the violence, exposure to violence in school and the ways of reacting to violence. In the frame of quantitative analysis of the data the following was applied: percentual research of frequencies and Pierson's hi-square test (x2 for testing of hyphothesis about the significance of differences. The main results of the research showed: a There is no statistically significant difference in exposure to violence in school between male and female students of primary school age; both genders are exposed to verbal and physical violence and male students (45.7% are more exposed to physical, and female students (38.3% are more exposed to verbal violence. bThere is no statistically significant difference in the readiness of students considering their gender to help another

  17. The significance of small streams (United States)

    Wohl, Ellen


    Headwaters, defined here as first- and secondorder streams, make up 70%‒80% of the total channel length of river networks. These small streams exert a critical influence on downstream portions of the river network by: retaining or transmitting sediment and nutrients; providing habitat and refuge for diverse aquatic and riparian organisms; creating migration corridors; and governing connectivity at the watershed-scale. The upstream-most extent of the channel network and the longitudinal continuity and lateral extent of headwaters can be difficult to delineate, however, and people are less likely to recognize the importance of headwaters relative to other portions of a river network. Consequently, headwaters commonly lack the legal protections accorded to other portions of a river network and are more likely to be significantly altered or completely obliterated by land use.

    International Nuclear Information System (INIS)

    Domaratzki, Z.


    It has long been recognized that no emergency core cooling system (ECCS) could be absolutely guaranteed to prevent fuel failures. In 1976 the Atomic Energy Control Board decided that the objective for an ECCS should be to prevent fuel failures, but if the objective could not be met it should be shown that the consequences are acceptable for dual failures comprising any LOCA combined with an assumed impairment of containment. Out of the review of the Bruce A plant came the definition of 'no significant fuel failures': for any postulated LOCA combined with any one mode of containment impairment the resultant dose to a person at the edge of the exclusion zone is less than the reference dose limits for dual failures

  19. Ritual Significance in Mycenaean Hairstyles

    Directory of Open Access Journals (Sweden)

    Hsu, Florence Sheng-chieh


    Full Text Available Although the frescoes excavated from Bronze Age sites on the Greek mainland provide evidence for female figures in the Mycenaean society, the hairstyles of these figures have not been studied in detail. As in many other ancient cultures, hairstyles were not only an exhibition of beauty and fashion, but they also represented certain age groups or a person’s social status. The Mycenaeans inherited many of their hairstyles from their Minoan predecessors, although differences existed as well. It is also possible there may have been a shift in meaning for seemingly similar looking hairstyles from the Minoan to the Mycenaean periods. Female figures, which compose most of the Mycenaean figures in frescoes known to date, are fine examples for discussing the artistic representation and potential significance of Mycenaean hairstyles. By comparing with Minoan hairstyles, discussions of Mycenaean examples lead to conclusions in the relationship between hairstyles and ritual activities in the Mycenaean society.

    We exploit a nested school accountability reform to estimate the causal effect on teacher mobility, sorting, and student achievement. In 2003, lower-secondary schools in Oslo became accountable to the school district authority for student achievement. In 2005, information on school performance in lower secondary education also became public. Using a difference-in-difference-in-difference approach, we find a significant increase in teacher mobility and that almost all non-stayers leave the tea...

  8. Significant biases affecting abundance determinations (United States)

    Wesson, Roger


    I have developed two highly efficient codes to automate analyses of emission line nebulae. The tools place particular emphasis on the propagation of uncertainties. The first tool, ALFA, uses a genetic algorithm to rapidly optimise the parameters of gaussian fits to line profiles. It can fit emission line spectra of arbitrary resolution, wavelength range and depth, with no user input at all. It is well suited to highly multiplexed spectroscopy such as that now being carried out with instruments such as MUSE at the VLT. The second tool, NEAT, carries out a full analysis of emission line fluxes, robustly propagating uncertainties using a Monte Carlo technique.Using these tools, I have found that considerable biases can be introduced into abundance determinations if the uncertainty distribution of emission lines is not well characterised. For weak lines, normally distributed uncertainties are generally assumed, though it is incorrect to do so, and significant biases can result. I discuss observational evidence of these biases. The two new codes contain routines to correctly characterise the probability distributions, giving more reliable results in analyses of emission line nebulae.

  9. Astrobiological significance of chemolithoautotrophic acidophiles (United States)

    Pikuta, Elena V.; Hoover, Richard B.


    For more than a century (since Winogradsky discovered lithautotrophic bacteria) there has been a dilemma in microbiology about life that first inhabited the Earth. Which types of life forms first appeared in the primordial oceans during the earliest geological period on Earth as the primary ancestors of modern biological diversity? How did a metabolism of ancestors evolve: from lithoautotrophic to lithoheterotrophic and organoheterotrophic or from organoheterotrophic to organautotrophic and lithomixotrophic types? At the present time, it is known that chemolithoheterotrophic and chemolithoautotrophic metabolizing bacteria are wide spread in different ecosystems. On Earth the acidic ecosystems are associated with geysers, volcanic fumaroles, hot springs, deep sea hydrothermal vents, caves, acid mine drainage and other technogenic ecosystems. Bioleaching played a significant roel on a global geological scale during the Earth's formation. This important feature of bacteria has been successfully applied in industry. The lithoautotrophs include Bacteria and Archaea belonging to diverse genera containing thermophilic and mesophilic species. In this paper we discuss the lithotrophic microbial acidophiles and present some data with a description of new acidophilic iron- and sulfur-oxidizing bacterium isolated from the Chena Hot Springs in Alaska. We also consider the possible relevance of microbial acidophiles to Venus, Io, and acidic inclusions in glaciers and icy moons.

    This report summarizes the work performed under the project (3z(BStatitically significant relational data mining.(3y (BThe goal of the project was to add more statistical rigor to the fairly ad hoc area of data mining on graphs. Our goal was to develop better algorithms and better ways to evaluate algorithm quality. We concetrated on algorithms for community detection, approximate pattern matching, and graph similarity measures. Approximate pattern matching involves finding an instance of a relatively small pattern, expressed with tolerance, in a large graph of data observed with uncertainty. This report gathers the abstracts and references for the eight refereed publications that have appeared as part of this work. We then archive three pieces of research that have not yet been published. The first is theoretical and experimental evidence that a popular statistical measure for comparison of community assignments favors over-resolved communities over approximations to a ground truth. The second are statistically motivated methods for measuring the quality of an approximate match of a small pattern in a large graph. The third is a new probabilistic random graph model. Statisticians favor these models for graph analysis. The new local structure graph model overcomes some of the issues with popular models such as exponential random graph models and latent variable models.

  11. Statistical Significance for Hierarchical Clustering (United States)

    Kimes, Patrick K.; Liu, Yufeng; Hayes, D. Neil; Marron, J. S.


    Summary Cluster analysis has proved to be an invaluable tool for the exploratory and unsupervised analysis of high dimensional datasets. Among methods for clustering, hierarchical approaches have enjoyed substantial popularity in genomics and other fields for their ability to simultaneously uncover multiple layers of clustering structure. A critical and challenging question in cluster analysis is whether the identified clusters represent important underlying structure or are artifacts of natural sampling variation. Few approaches have been proposed for addressing this problem in the context of hierarchical clustering, for which the problem is further complicated by the natural tree structure of the partition, and the multiplicity of tests required to parse the layers of nested clusters. In this paper, we propose a Monte Carlo based approach for testing statistical significance in hierarchical clustering which addresses these issues. The approach is implemented as a sequential testing procedure guaranteeing control of the family-wise error rate. Theoretical justification is provided for our approach, and its power to detect true clustering structure is illustrated through several simulation studies and applications to two cancer gene expression datasets.

  13. Detection of significant protein coevolution. (United States)

    Ochoa, David; Juan, David; Valencia, Alfonso; Pazos, Florencio


    The evolution of proteins cannot be fully understood without taking into account the coevolutionary linkages entangling them. From a practical point of view, coevolution between protein families has been used as a way of detecting protein interactions and functional relationships from genomic information. The most common approach to inferring protein coevolution involves the quantification of phylogenetic tree similarity using a family of methodologies termed mirrortree. In spite of their success, a fundamental problem of these approaches is the lack of an adequate statistical framework to assess the significance of a given coevolutionary score (tree similarity). As a consequence, a number of ad hoc filters and arbitrary thresholds are required in an attempt to obtain a final set of confident coevolutionary signals. In this work, we developed a method for associating confidence estimators (P values) to the tree-similarity scores, using a null model specifically designed for the tree comparison problem. We show how this approach largely improves the quality and coverage (number of pairs that can be evaluated) of the detected coevolution in all the stages of the mirrortree workflow, independently of the starting genomic information. This not only leads to a better understanding of protein coevolution and its biological implications, but also to obtain a highly reliable and comprehensive network of predicted interactions, as well as information on the substructure of macromolecular complexes using only genomic information.

    This study investigated the stable and transient genetic and environmental contributions to individual differences in number knowledge in the transition from preschool (age 5) to Grade 1 (age 7) and to the predictive association between early number knowledge and later math achievement (age 10-12). We conducted genetic simplex modeling across these three time points. Genetic variance was transmitted from preschool number knowledge to late-elementary math achievement; in addition, significant genetic innovation (i.e., new influence) occurred at ages 10 through 12 years. The shared and nonshared environmental contributions decreased during the transition from preschool to school entry, but shared and nonshared environment contributed to the continuity across time from preschool number knowledge to subsequent number knowledge and math achievement. There was no new environmental contribution at time points subsequent to preschool. Results are discussed in light of their practical implications for children who have difficulties with mathematics, as well as for preventive intervention.

  15. Business schools' international networks for faculty development


    Pennarola F.


    Business schools are facing ever increasing internationalization: students are far less homogenous than before, faculty members come from different countries, and teaching is carried out in second (or even third) languages. As a result business schools and their teachers wrestle with new challenges as these changes accelerate. Teaching and Learning at Business Schools brings together contributions from business school managers and educators involved in the International Teachers Programm...

  16. Regional and global significance of nuclear energy

    International Nuclear Information System (INIS)

    Schilling, H.D.


    Measures to combat poverty and improve the standard of living in countries of the Third World will inevitably boost global demand for energy, and energy conservation measures will not be able to offset this increase. Nuclear energy will regain significance in the framework of approaches adopted to resolve the energy problem, which primarily is an ecologic problem created by an extremely large flow of materials. The extraordinarily high energy density of nuclear fuels can contribute to markedly reduce the flow of materials; and at that, electric energy is an efficient substitute for primary energy forms. Thus nuclear electricity generation is of double benefit to the ecology. Engineering goals in nuclear technology thus gain a service aspect, with progress in power plant engineering and design aiming not only at enhanced engineered safety, but also at regaining public acceptance of and confidence in nuclear power plant technology.

  20. Cognitive Determinants of Academic Performance in Nigerian Pharmacy Schools (United States)

    Sansgiry, Sujit S.; Ukwe, Chinwe V.


    Objective. To evaluate cognitive factors that might influence academic performance of students in Nigerian pharmacy schools. Methods. A cross-sectional, multi-center survey of Nigerian pharmacy students from 7 schools of pharmacy was conducted using 2 validated questionnaires measuring cognitive constructs such as test anxiety, academic competence, test competence, time management, and strategic study habits. Results. Female students and older students scored significantly better on time management skills and study habits, respectively. Test anxiety was negatively associated with academic performance while test competence, academic competence, and time management were positively associated with academic performance. These 4 constructs significantly discriminated between the lower and higher performing students, with the first 2 contributing to the most differences. Conclusion. Test and academic competence, test anxiety, and time management were significant factors associated with low and high academic performance among Nigerian pharmacy students. The study also demonstrated the significant effects of age, gender, and marital status on these constructs. PMID:27168614

  2. US Department of Agriculture School Breakfast Program. (United States)

    Kennedy, E; Davis, C


    This article reviews the history of the US Department of Agriculture School Breakfast Program (SBP) and provides a synthesis of factors influencing participation rates. Certain children are more likely to participate than others, such as those in lower grades and those from low-income households, and African American, Hispanic, and male students. A few studies in the past 25 y have examined the effectiveness of the SBP in improving the diets and nutritional status of children. The overall pattern that emerges from these studies is that the SBP contributes to improved nutrient intake in program participants. Less attention has been devoted to assessing the effects of SBP on cognitive development. Some of the evidence reviewed here suggests that the SBP significantly improves school performance and reduces absenteeism and tardiness. Future directions for research and operation of the SBP are discussed in light of the changing dietary profile of American children.

  3. Jesuits' Contribution to Meteorology. (United States)

    Udías, Agustín


    Starting in the middle of the nineteenth century, as part of their scientific tradition, Jesuits founded a considerable number of meteorological observatories throughout the world. In many countries, Jesuits established and maintained the first meteorological stations during the period from 1860 to 1950. The Jesuits' most important contribution to atmospheric science was their pioneer work related to the study and forecast of tropical hurricanes. That research was carried out at observatories of Belén (Cuba), Manila (Philippines), and Zikawei (China). B. Viñes, M. Decheyrens, J. Aigué, and C.E. Deppermann stood out in this movement.

  4. Examining suicide: imaging's contributions. (United States)

    Church, Elizabeth J


    For many people, the death of hope leads inexorably to the conclusion that the only viable solution, the only way to put an end to unendurable pain, is suicide. What leads a person to commit this final, desperate act, and how might we predict, intervene, and prevent suicide? Health care workers, including radiologic technologists, can play an important role in detecting warning signs in patients and in better understanding what factors may lead to suicide. Although certain forms of suicide such as suicide bombings and assisted suicide are beyond its scope, this article explores medical imaging's contributions to the study of this phenomenon.

  9. Job satisfaction among urban secondary-school teachers in Namibia

    Directory of Open Access Journals (Sweden)

    Evy George


    Full Text Available An exploratory study on the role of extrinsic and intrinsic factors in determining job satisfaction amongst urban secondary-school teachers in Namibia was undertaken. Biographical variables pertaining to the teachers' gender, age, marital status, school resources, teaching experience, academic qualifications, and rank were investigated to determine whether these had any significant relevance, or made any notable contribution, to the level of job satisfaction experienced. Also, the correlation between burnout and job satisfaction was investigated to determine the extent to which these two factors are related. A sample of 337 secondary-school teachers randomly selected from 17 government schools, in the Windhoek region of Namibia, voluntarily participated in the study. Results showed significant levels of dissatisfaction pertaining to intrinsic factors of work and, more especially, those factors relating to school area and rank. A significant correlation between levels of burnout and job satisfaction was found, particularly in respect of emotional exhaustion and depersonalization, which were shown to correlate with low levels of job satisfaction. Limitations and recommendations pertaining to the study are discussed.

  10. School connectedness and high school graduation among maltreated youth. (United States)

    Lemkin, Allison; Kistin, Caroline J; Cabral, Howard J; Aschengrau, Ann; Bair-Merritt, Megan


    Maltreated youth have higher rates of school dropout than their non-maltreated peers. School connectedness is a modifiable predictor of school success. We hypothesized maltreated youth's school connectedness (supportive relationships with adults at school and participation in school clubs) would be positively associated with high school graduation. We included youth with at least one Child Protective Services (CPS) report by age twelve from Longitudinal Studies of Child Abuse and Neglect, a prospective cohort study. Participation in extracurricular activities and adult relationships reported at age 16, high school graduation/General Education Development (GED) status reported at age 18, and demographics were provided by youth and caregivers. Maltreatment data were coded from CPS records. The outcome was graduation/receipt of GED. Multivariable logistic regressions examined the association between school connectedness and graduation/receipt of GED, controlling for confounders. In our sample of 318 maltreated youth, 73.3% graduated. School club was the only activity with a statistically significant association with graduation in bivariate analysis. Having supportive relationships with an adult at school was not significantly associated with graduation, though only 10.7% of youth reported this relationship. Maltreated youth who participated in school clubs had 2.54 times the odds of graduating, adjusted for study site, gender, poverty status, caregiver high school graduation status, and age at first CPS report (95% CI: [1.02, 6.33]). Few maltreated youth reported relationships with adults at school, and additional efforts may be needed to support these vulnerable youth. School club participation may represent an opportunity to modify maltreated youth's risk for school dropout. Copyright © 2017 Elsevier Ltd. All rights reserved.

  11. Violence and school shootings. (United States)

    Flannery, Daniel J; Modzeleski, William; Kretschmar, Jeff M


    Multiple-homicide school shootings are rare events, but when they happen they significantly impact individuals, the school and the community. We focus on multiple-homicide incidents and identified mental health issues of shooters. To date, studies of school shootings have concluded that no reliable profile of a shooter exists, so risk should be assessed using comprehensive threat assessment protocols. Existing studies primarily utilize retrospective case histories or media accounts. The field requires more empirical and systematic research on all types of school shootings including single victim incidents, those that result in injury but not death and those that are successfully averted. We discuss current policies and practices related to school shootings and the role of mental health professionals in assessing risk and supporting surviving victims.

  12. The effect of a total rewards strategy on school teachers’ retention

    Boitomelo Makhuzeni


    Full Text Available Orientation: South African schools are facing significant challenges to retain a talented pool of school teachers. A total rewards strategy could assist schools to reduce teacher turnover. Research purpose: The aim of this study was to determine the effect of a total rewards strategy on the turnover intentions of school teachers in the North-West province. Motivation: The under supply of quality teachers has negative consequences for both school pupils and the larger community. Research approach, design and method: A qualitative research approach was followed using semi-structured interviews to gather data from teachers in the North-West province (N = 6. Main findings: The findings showed that performance management, career development and compensations of teachers were poorly applied in schools. Teachers strongly considered leaving the teaching profession as a result of poor rewards. The participants were fairly satisfied with their work benefits and work-life balance. Practical/managerial implications: School management should implement reward practices and policies that will attract and enhance retention of school teachers. Contribution: This research highlighted the problematic areas in the reward systems for school teachers and the subsequent impact thereof on their turnover intentions.

  19. Defined contribution health benefits. (United States)

    Fronstin, P


    This Issue Brief discusses the emerging issue of "defined contribution" (DC) health benefits. The term "defined contribution" is used to describe a wide variety of approaches to the provision of health benefits, all of which have in common a shift in the responsibility for payment and selection of health care services from employers to employees. DC health benefits often are mentioned in the context of enabling employers to control their outlay for health benefits by avoiding increases in health care costs. DC health benefits may also shift responsibility for choosing a health plan and the associated risks of choosing a plan from employers to employees. There are three primary reasons why some employers currently are considering some sort of DC approach. First, they are once again looking for ways to keep their health care cost increases in line with overall inflation. Second, some employers are concerned that the public "backlash" against managed care will result in new legislation, regulations, and litigation that will further increase their health care costs if they do not distance themselves from health care decisions. Third, employers have modified not only most employee benefit plans, but labor market practices in general, by giving workers more choice, control, and flexibility. DC-type health benefits have existed as cafeteria plans since the 1980s. A cafeteria plan gives each employee the opportunity to determine the allocation of his or her total compensation (within employer-defined limits) among various employee benefits (primarily retirement or health). Most types of DC health benefits currently being discussed could be provided within the existing employment-based health insurance system, with or without the use of cafeteria plans. They could also allow employees to purchase health insurance directly from insurers, or they could drive new technologies and new forms of risk pooling through which health care services are provided and financed.
