Full Text Available Positive attitude towards inclusion of children with disabilities in Physical Education (PE classes is one quite important factor for successful implementation of inclusive education. The aim of this study was to examine the predictors of attitude of the students as future PE teachers towards inclusion in PE. In this study, the predictors in the field of personality, professional competences for working with children with disabilities and certain personal characteristics (gender were included. The sample included 221 students of the final year of studies at the Faculty of Sport and Physical Education in Belgrade, Niš and Novi Sad. In order to measure the attitude towards inclusion in PE, the instrument of Attitude Toward Inclusive Physical Education was used. In the field of personality, a trait of openness to experience was examined, which was measured using the HEXACO PI-R instrument. An additional questionnaire was also designed by which the students were asked to indicate their gender and professional competences for working with children with disabilities: their average mark during the studies, subjective assessment of the level of knowledge and skills required for working with children with disabilities acquired in the course of their studies (self-assessment of professional competence and experience in working with children with disabilities during their professional practice. The results of multiple regression analysis showed that openness to experience, self-assessment of professional competence and gender were significant predictors. The results indicate that, during the training for teaching profession, it is necessary to develop students' specific competences required for the work in inclusive education as well as to create the teaching atmosphere which will enhance inquisitiveness and creativity as significant determinants of the trait of openness to experience.

Problems of safety and risk in physical education

Directory of Open Access Journals (Sweden)

Robert Podstawski

2015-10-01

Full Text Available Purpose: One of the methodology issues in Physical Education is providing children with safety. The purpose of this work is to present basic concepts of safety at Physical Education classes. Material & Methods: The issues connected with safety at classes of Physical Education have been discussed in the subsections, each of which focuses on different concepts such as: legal safety regulations, causes of hazards, theoretical models of preventing hazards at P.E. classes, nutrition programs related to exercise’s fulfillment, prevention of heat disorders and dehydration. Results: According to experts’ opinion, the causes of safety hazards at P.E. classes can be divided into three groups: caused by instructor, caused by a student, and finally hazards technical in nature. The number of accidents during P.E. classes is still substantial, and among most common hazards there are the following: fractures of upper and lower limbs, dislocations, contusions, tendonitis, muscle tear and cuts. Curiously, boys experience such injuries more frequently than girls. Conclusions: Even though safety rules at Physical Education classes are defined by specific regulations, children’s absolute safety is never guaranteed. In order to diminish the number of misadventures, instructor is obliged not only to adhere to the norms but also to teach children to safety rules.

California law has standards for physical education (PE) instruction in K-12 public schools; audits found that the Los Angeles Unified School District did not enforce the standards. In 2009, the district adopted a PE policy to comply with these standards. This study aimed to evaluate the outcomes of the PE policy in district schools. PE class observations were conducted using the System for Observing Fitness Instruction Time in the 2010-2011 and 2011-2012 school years in an income-stratified random sample of 34 elementary, middle, and high schools to assess changes in PE class size, class duration, and time students spent in moderate to vigorous physical activity. PE class duration increased in high-income elementary schools. Mean class size decreased in low-income middle schools. There was limited implementation of the PE policy 2 years after passage. Opportunities exist to continue monitoring and improving PE quantity and quality.

Physical Education Policies and Practices in California Private Secondary Schools.

Science.gov (United States)

Kahan, David; McKenzie, Thomas L

2017-02-01

Physical education (PE) is mandated in most states, but few studies of PE in private schools exist. We assessed selected PE policies and practices in private secondary schools (grades 6 to 12) in California using a 15-item questionnaire related to school characteristics and their PE programs. Responding schools (n = 450; response rate, 33.8%) were from 37 counties. Most were coeducational (91.3%) and had a religious affiliation (83%). Secular schools had more PE lessons, weekly PE min, and smaller class sizes. Most schools met guidelines for class size, but few met national recommendations for weekly PE minutes (13.7%), not permitting substitutions for PE (35.6%), and programs being taught entirely by PE specialists (29.3%). Private schools, which serve about 5 million US children and adolescents, may be falling short in providing quality PE. School stakeholders should encourage adoption and implementation of policies and practices that abide by professional guidelines and state statutes.

Parametric embedding for class visualization.

Science.gov (United States)

Iwata, Tomoharu; Saito, Kazumi; Ueda, Naonori; Stromsten, Sean; Griffiths, Thomas L; Tenenbaum, Joshua B

2007-09-01

We propose a new method, parametric embedding (PE), that embeds objects with the class structure into a low-dimensional visualization space. PE takes as input a set of class conditional probabilities for given data points and tries to preserve the structure in an embedding space by minimizing a sum of Kullback-Leibler divergences, under the assumption that samples are generated by a gaussian mixture with equal covariances in the embedding space. PE has many potential uses depending on the source of the input data, providing insight into the classifier's behavior in supervised, semisupervised, and unsupervised settings. The PE algorithm has a computational advantage over conventional embedding methods based on pairwise object relations since its complexity scales with the product of the number of objects and the number of classes. We demonstrate PE by visualizing supervised categorization of Web pages, semisupervised categorization of digits, and the relations of words and latent topics found by an unsupervised algorithm, latent Dirichlet allocation.

Science.gov (United States)

Jin, Jooyeon; Yun, Joonkoo

2013-07-01

The purpose of this study was to examine three frameworks, (a) process-product, (b) student mediation, and (c) classroom ecology, to understand physical activity (PA) behavior of adolescents with and without disabilities in middle school inclusive physical education (PE). A total of 13 physical educators teaching inclusive PE and their 503 students, including 22 students with different disabilities, participated in this study. A series of multilevel regression analyses indicated that physical educators' teaching behavior and students' implementation intentions play important roles in promoting the students' PA in middle school inclusive PE settings when gender, disability, lesson content, instructional model, and class location are considered simultaneously. The findings suggest that the ecological framework should be considered to effectively promote PA of adolescents with and without disabilities in middle school PE classes.

Moreno Murcia, Juan A; Parra Rojas, Nicolás; González-Cutre Coll, David

2008-11-01

The purpose of this study was to analyze some factors that influence amotivation in physical education classes. A sample of 399 students, of ages 14 to 16 years, was used. They completed the Perceived Autonomy Support Scale in Exercise Settings (PASSES), the Social Goal Scale-Physical Education (SGS-PE), the factor of the Basic Psychological Needs in Exercise Scale (BPNES) adapted to physical education and the amotivation> factor of the Perceived Locus of Causality Scale (PLOC). The psychometric properties of the PASSES were analyzed, as this scale had not been validated to the Spanish context. In this analysis, the scale showed appropriate validity and reliability. The results of the structural equation model indicated that social responsibility and social relationship goals positively predicted perception of relatedness, whereas the context of autonomy support did not significantly predict it. In turn, perception of relatedness negatively predicted amotivation. The findings are discussed with regard to enhancing students' positive motivation.

The effects of application of music on the formation of students’ attitude towards physical education

2014-01-01

Full Text Available A positive attitude towards physical education (PE is an important component of students’ engagement in classes and extracurricular physical activities. Relying on students’ interests when planning the class work can contribute to the formation of such an attitude. The research was aimed at verifying the effects of the experimental programme “Inclusion of music in Physical Education classes” on the formation of students’ attitude towards PE. An experiment with parallel groups that lasted for 26 classes was applied in the research on the sample of 141 primary school students attending the seventh grade. In the initial and final testing two instruments for measuring the attitudes were applied: the Students’ Attitudes toward Physical Education - SATPE and the Connotative Differential (CD-15. In the final testing, the experimental group also completed the questionnaire on students’ assessment of classes with and without music. The analysis of variance has shown that the experimental group achieved considerably higher scores at the final testing compared to the initial on the cognitive and conative subscales of the CD-15 instrument. This change was not linked to gender, PE grade and involvement in music. It has been shown that students in the experimental group assessed more positively the classes accompanied by music compared to the classes without music, measured by the questionnaire on students’ assessment of classes with and without music. It can be concluded that the application of music has influenced the development of a more positive attitude towards PE, observed via the cognitive and conative dimension, which points to the fact that it is justifiable and desirable to use music in PE education.

Bevans, Katherine; Fitzpatrick, Leslie-Anne; Sanchez, Betty; Forrest, Christopher B.

2012-01-01

This study was conducted to identify student characteristics and instructional factors that impact student engagement in physical education (PE). Data were derived from the systematic observation of 124 sessions taught by 31 physical educators and the administration of health and PE engagement questionnaires to 2,018 students in grades 5–8. Physical activity was directly affected by student engagement and perceived competence in PE and indirectly affected by students’ body image through its association with PE engagement. Multilevel analyses revealed that the proportion of class time devoted to game play was negatively associated with student engagement in PE. Although less frequently used during PE sessions, skill practice was positively associated with student engagement and inactive instruction was negatively associated with student engagement. These effects were particularly pronounced among students with poor competence beliefs. Implications for PE instructional practice and future research are presented. PMID:22844176

Dragoljub Višnjić

2010-09-01

Full Text Available The relations of students achievement and motivation for involvement in PE classes were examined in a sample of 247 seventh-grade elementary school students of both sexes. The independent variables in the study were: sex, general success of the previous grade, PE grade, students’ opinion on sufficiency of knowledge acquired through instruction process, students’ involvement in sport. The scale for measurement of motivation consisted of 29 items obtained by adaptation of the Scale for measurement of motives of sports’ achievement. Correlation analysis, multiple regression analysis and chi square test were preformed. It was established that male students manifested higher motivation that the females. The assumptions: that females will have better PE grades that the male students; that students’ success was negatively related to involvement in sport; that PE grade was connected to involvement in sport; that general success was negatively related to students’ involvement in PE and that PE grade is positively related to students’ motivation for involvement in instruction, were not confirmed.

2014-10-01

Enhancing students' academic engagement is the key element of the educational process; hence, research in this area has focused on understanding the mechanisms that can lead to increased academic engagement. The present study investigated the relation between motivation and grades in physical education (PE) employing a 3-year longitudinal design. Three hundred fifty-four Greek high school students participated in the study. Students completed measures of motivation to participate in PE on six occasions; namely, at the start and the end of the school year in the first, second, and third year of junior high school. Students' PE grades were also recorded at these time points. The results of the multilevel growth models indicated that students' PE grades increased over the 3 years and students had better PE grades at the end of each year than at the beginning of the subsequent year. In general, students and classes with higher levels of controlling motivation achieved lower PE grades, whereas higher levels of autonomous motivation were associated with higher PE grades. These findings provide new insight on the associations between class- and individual-level motivation with objectively assessed achievement in PE. © 2014 John Wiley & Sons A/S.

The aim of this work is to evaluate the effect of the Bio-PE content on the crystallinity and rheological properties of PLA/Bio-PE blend. The blends containing 05 and 15% of Bio-PE were prepared by extrusion followed by injection molding and characterized by X-Ray Diffraction (XRD) and rheological properties at low and high shear rates. XRD results indicated that the PLA present low crystallinity and this behavior was not changed with the addition of Bio-PE, regardless of Bio-PE content. Rheological properties results indicated that at low shear rates the viscosity of the PLA/Bio-PE increased with the increase in the Bio-PE content while at high shear rates the viscosities where almost similar, which may be ascribed to the orientation of Bio-PE particles in the flow direction or by the viscous dissipation.

2003-07-01

The leaking of the PE-2 pipeline into Guanabara Bay. Rio de Janeiro, during late 2000 attracted widespread attention in Brazil and around the world. The safe design and operation of pipelines transporting hot, heavy hydrocarbons is critical for avoiding future oil spills. Conventional methods for designing pipelines that transport hot products rely on soil overburden to control upheaval buckling. However, extremely poor soil strength, combined with sediment mobility, led to the failure of the PE-2 pipeline. The serious consequences led TRANSPETRO to specify that the highest standards (DNV Safety Class High) were to be applied to the design and fabrication of the replacement PE-3 pipeline. The design was also required to withstand a large number of operational cycles, i.e. three (3) hot to cold cycles per week for the entire 40 years of the pipeline's design life. To meet these design challenges, several pipeline configurations were examined. A unique zigzag configuration was selected for this pipeline project. (author)

Educational and social class assortative mating in fertile British couples.

Krzyżanowska, Monika; Mascie-Taylor, C G Nicholas

2014-01-01

Positive assortative mating for education and social position has been widely reported in a number of countries, but very few studies have tested whether or not educational or social class homogamy is related to differential fertility. This study examined the relationship between educational and social class assortative mating and fertility in a British national cohort. The analyses were based on 7452 husband-wife pairs from the British National Child Development Study (NCDS). The mean fertility was 3.22 children per couple; the number of children significantly increased from higher to lower social classes and from the more educated to the less educated. The extent of assortative mating for social class and educational level was related to fertility; as educational assortative mating decreased so did the average number of children, whereas the opposite trend was observed for social class. When assortative mating for education and social class were considered together, educational assortative mating was the more significant predictor of the number of children and educationally homogamous couples had higher fertility independent of their social class assortative mating. The relationship between assortative mating and fertility for education and social class appeared to be acting in the opposite direction.

Attitudes of early adolescent age students towards physical education

Directory of Open Access Journals (Sweden)

Lazarević Dušanka

2015-01-01

Full Text Available Studies have shown that a positive attitude towards physical education (PE is in connection with students' engagement in PE classes and with the development of an active lifestyle. The objective of this study was to examine attitudes of early adolescent age students towards physical education, as well as to examine whether such attitudes vary with regard to gender, grade they attend and students' engagement in sport and physical exercises in extracurricular activities. The research was conducted on the sample of 531 students from 6th to 8th grade. The instrument Student's Attitudes toward Physical Education - SATPE was used to measure student's attitude towards PE. A special questionnaire was used to collect data on gender, grade and engagement in sport and physical exercising outside school. The results have shown that students have positive attitudes of moderate intensity towards physical education. MANOVA has shown that male students have more positive attitudes than female students, as well as that positivity of attitudes declines with age. Likewise, it was shown that students with more positive attitudes towards PE are more often engaged in physical exercises outside school. The connection between the attitude towards PE and involvement in organized sport was not confirmed. The paper presents suggestions for further research of students' attitude towards PE and its connection with physical activity of students.

Baker, Nancy A; Cook, James R; Redfern, Mark S

2009-01-01

This paper describes the inter-rater and intra-rater reliability, and the concurrent validity of an observational instrument, the Keyboard Personal Computer Style instrument (K-PeCS), which assesses stereotypical postures and movements associated with computer keyboard use. Three trained raters independently rated the video clips of 45 computer keyboard users to ascertain inter-rater reliability, and then re-rated a sub-sample of 15 video clips to ascertain intra-rater reliability. Concurrent validity was assessed by comparing the ratings obtained using the K-PeCS to scores developed from a 3D motion analysis system. The overall K-PeCS had excellent reliability [inter-rater: intra-class correlation coefficients (ICC)=.90; intra-rater: ICC=.92]. Most individual items on the K-PeCS had from good to excellent reliability, although six items fell below ICC=.75. Those K-PeCS items that were assessed for concurrent validity compared favorably to the motion analysis data for all but two items. These results suggest that most items on the K-PeCS can be used to reliably document computer keyboarding style.

Students’ motivation in a disc golf-lesson and a soccer-lesson: An experimental study in the Physical Education setting

2017-09-01

Full Text Available One of the purposes of physical education (PE in both Norway and Denmark is that PE should inspire to a lifelong active lifestyle. Based on the self-determination theory, the aim of the present study was to compare students’ intrinsic motivation, extrinsic motivation, and perceived competence in a lifestyle sport inspired PE-lesson (disc golf to a traditional PE-lesson (soccer and general PE. In addition, we aimed to investigate whether differences in motivation and perceived competence were conditional of the students’ relative attitude toward PE. The result of the study revealed that perceived competence was higher in the disc golf-lesson compared to the soccer-lesson and general PE. No overall differences in intrinsic motivation were found. However, when investigating differences in intrinsic motivation according to the students’ relative attitude toward PE, the results indicated that the students with a negative attitude toward PE was significantly more intrinsically motivated in disc golf-lesson compared to soccer-lesson and general PE. The findings may be seen as further recommendations to physical educators to vary the activity choices in physical education classes.

Physical education issues for students with autism: school nurse challenges.

Science.gov (United States)

Rutkowski, Elaine M; Brimer, Debbie

2014-08-01

Extant studies indicate persons with autism have difficulties in social interaction, verbal and nonverbal communication, repetitive behaviors, and poor ability to generalize learned skills. Obesity has also been identified as significantly affecting children with autism spectrum disorders (ASD). Negative experience in physical education (PE) may be the antecedent behavior to lack of activities that are mediators to sedentary lifestyles and contributors to the chronic illnesses associated with overweight and obesity. Students with ASD often cannot perform required activities to meet required PE standards. It is imperative school nurses be aware of the many challenges students with ASD bring into a PE class. School nurses provide education for the members of the school community, including the Individualized Education Plan team, regarding the need for attention to limitations, including physical activity, of students with ASD. © The Author(s) 2013.

Correlates of state enactment of elementary school physical education laws.

Monnat, Shannon M; Lounsbery, Monica A F; Smith, Nicole J

2014-12-01

To describe variation in U.S. state elementary school physical education (PE) policies and to assess associations between state PE policy enactment and education funding, academic achievement, sociodemographic disadvantage, and political characteristics. U.S. state laws regarding school PE time, staffing, curriculum, fitness assessment, and moderate-to-vigorous physical activity (MVPA) in 2012 were classified as strong/specific, weak/nonspecific, or none based on codified law ratings within the Classification of Laws Associated with School Students (C.L.A.S.S.). Laws were merged with state-level data from multiple sources. Logistic regression was used to determine associations between state characteristics and PE laws (N=51). Laws with specific PE and MVPA time requirements and evidence-based curriculum standards were more likely in states with low academic performance and in states with sociodemographically disadvantaged populations. School day length was positively associated with enacting a PE curriculum that referenced evidence-based standards. School funding and political characteristics were not associated with PE laws. Limited time and high-stake testing requirements force schools to prioritize academic programs, posing barriers to state passage of specific PE laws. To facilitate PE policy enactment, it may be necessary to provide evidence on how PE policies can be implemented within existing time and staffing structures. Copyright © 2014 Elsevier Inc.

2012-08-01

We examined whether public schools in states with specific and stringent physical education (PE) laws, as assessed by the Physical Education-Related State Policy Classification System (PERSPCS), available on the Classification of Laws Associated with School Students (C.L.A.S.S.) Web site, reported more weekly PE time in the most recent School Health Policies and Programs Survey (SHPPS). Schools (n=410) were grouped by their state's PERSPCS time requirement scores (none, nonspecific requirement, or specific requirement). Average weekly school-level PE was calculated using the SHPPS-reported PE minutes. Weighted analyses determined if PE minutes/week differed by PERSPCS group. Schools in states with specific requirement laws averaged over 27 and 60 more PE minutes/week at the elementary and middle school levels, respectively, compared with schools within states with nonspecific laws and over 40 and 60 more PE minutes per week, respectively, compared with elementary and middle schools in states with no laws. High school results were nonsignificant. Public health guidelines recommend at least 60 minutes of daily physical activity for children, and PE may further this goal. Strong codified law with specific time requirements for PE may be an important tool contributing toward adequate PE time and daily physical activity recommendations.

A Motivational Model of Physical Education and Links to Enjoyment, Knowledge, Performance, Total Physical Activity and Body Mass Index

Directory of Open Access Journals (Sweden)

Arto Gråstén, Anthony Watt

2017-09-01

Full Text Available The present paper examined the full sequence of the Hierarchical Model of Motivation in physical education (PE including motivational climate, basic psychological needs, intrinsic motivation, and related links to contextual enjoyment, knowledge, performance, and total moderate to vigorous physical activity (MVPA. Gender differences and correlations with body mass index (BMI were also analyzed. Cross-sectional data was represented by self-reports and objective assessments of 770 middle school students (52% of girls in North-East Finland. The results showed that task-involving climate in girls’ PE classes was related to enjoyment and knowledge through physical competence and intrinsic motivation, whereas task-involving climate was associated with enjoyment and knowledge via competence and autonomy, and total MVPA via autonomy, intrinsic motivation, and knowledge within boys. This may indicate that girls and boys perceive PE classes in a different way. Graded PE assessments appeared to be essential in motivating both girls and boys to participate in greater total MVPA, whereas BMI was negatively linked with competence and social relatedness only among girls. Although, the current and previous empirical findings supported task-involving teaching methods in PE, in some cases, ego-involving climate should be considered. Therefore, both task- and ego-involving teaching practices can be useful ways of developing preferred behaviors in PE classes.

Effect of HALS on radiation discoloration of PE

International Nuclear Information System (INIS)

Wang Huiliang; Wang Chun; Chen Wenxiu

2001-01-01

The effects of hindered amine light stabilizers (HALS) on the radiation-induced discoloration of polyethylene (PE) are studied by measuring the yellowness index (YI) of PE. It is found that all the HALS used are effective in preventing PE from radiation-induced discoloration. The YI of PE added pentamethyl HALS (PMPM, PPMPM) is a little higher than that of PE added corresponding tetramethyl HALS (TMPM, PTMPM) when radiation dose is low than 100 kGy, but when the radiation dose is higher than 100 kGy, the YI of PE added pentamethyl HALS is lower. Pentamethyl HALS is more effective in preventing PE from radiation-induced discoloration when radiation dose is higher. It is also found that polymeric HALS is more effective in preventing PE from radiation-induced discoloration than corresponding monomeric HALS when radiation dose is higher than 200 kGy. The formation of alkyl free radical, carbonyl after irradiation is measured. It is found that the relative concentration of free radical formed in PE added TMPM is higher than that of PE added PMPM when radiation dose is relatively high. The carbonyl index of PE containing pentamethyl HALS is less than that of PE containing tetramethyl HALS when radiation is relatively low, but the results is contrary when radiation dose is relatively high. It is believed that HALS prevents PE from radiation-induced discoloration by scavenging free radicals formed in irradiated PE

Full Text Available Australian youth (5–17 are exhibiting the most alarming statistics surrounding poor physical activity (PA levels and increasing correlating chronic disease trends (i.e. obesity. With schools well positioned to address such concerns, this study aimed to determine the type, frequency and intensity levels of PA being undertaken by children during their physical education (PE classes (Queensland, Australia. A cross-sectional descriptive study design was adopted, using a mixed methods approach across 10 primary schools (grades 1–5, with the purpose of determining if in fact there are appropriate PA levels undertaken and implemented by PE teachers, for school-aged students. Observation of 30 students was used to assess PE class practice with Primary Outcome Variables collected from Student Activity, Lesson Context and Teacher Interaction. Further questionnaires were administered to students (n = 80, PE specialists (n = 10 and principals (n = 10. Whilst this study specifically addresses the importance of correctly structured PE lessons, further attention is directed towards identifying the impact appropriately structured PA levels have on students’ wider social and emotional well-being. Schools are encouraged to prioritise the importance of PA at a school level, for example, through re-engaging key stakeholders to ensure the delivery methods meet national and international PA guidelines.

2016-09-01

Using the quasi-experimental design, this study examined the effect of autonomy support on self-determined motivation in elementary school physical education (PE) students. One hundred and twenty six participants were assigned to either the autonomy support group (n = 61) or the control group (n = 65) for a six-week intervention period. Perceived teacher autonomy, perceived autonomy in PE, and self-determined motivation in PE were pre- and post-tested using validated questionnaires. Significant increases in perceived teacher autonomy and perceived autonomy in PE were observed in the autonomy support group, but not in the control group. Intrinsic motivation was higher in the autonomy support group than that in the control group. From an experimental perspective, these findings suggest that the autonomy support was successfully manipulated in the PE classes, which in turn increased the students' perceived autonomy and intrinsic motivation.

Physical Education in relation to the inclusive education: conceptual and methodological reflections

Directory of Open Access Journals (Sweden)

David António Rodrigues

2008-05-01

Full Text Available Inclusive Education is a main educational orientation in most countries which signed the Salamanca Declaration in 1994. By defining the Inclusive Education (IE as being “for everybody and each individual”, we aim at creating na educative model that rejects exclusion and promotes learning without barriers. Physical Education (PE is part of the inclusive curriculum. Apparently, PE seems to be more receptive to Inclusion, but in fact PE teachers seem to have more difficulties to deal with the inclusion challenges. In PE there is a “double exclusion genealogy” that implies a greater difficulty to answer to diversity. In this article some strategies to improve teacher’s education and support are suggested, in order to make the inclusive quality of PE better.

Full Text Available Abstract Background Recent initiatives have been introduced by the UK government into secondary schools to increase pupils' access to physical activity (PA. Despite this, not enough is known about pupils' levels of physical activity or whether the delivery of these initiatives in schools facilitates or creates a barrier for pupils' PA. The aim of this study was to gain an understanding of adolescents PA levels from the perspective of those responsible for delivering physical education (PE in schools; heads of PE (HOPE and heads of school (HS. Methods Seventeen semi-structured qualitative interviews were carried out with a snowball sample of HOPE and HS in schools in the Northwest and Southwest of England. Thematic data analysis using NVIVO was used to identify emergent themes. Results 17 core themes were generated, 12 of which confirmed the findings from similar research. However, five themes relating to 'ethos of performance/elitism', 'lower fitness leads to lower ability', 'undervaluing activities within PE dept' or school as a whole', 'role of the school' and 'PE department doing all it can' offer valuable new insight into the factors which may encourage or prevent PA inside or outside the curriculum. Conclusion Despite many positive perceptions of the delivery of PE in schools, it is evident that barriers still exist within that delivery which discourages physical activity. More research is needed to particularly address the complex issues of elitism and the ethos of PA in schools.

2014-04-01

Full Text Available This study shows the development of some motivational dimensions of secondary school students when they are treated by the experimental way of teaching. The study was conducted on a sample of 240 pupils of The Secondary School Banovici, out of which 124 males and 116 females. The pupils were divided into two groups. The first group consisted of 120 pupils divided into four sections, out of which 73 males and 47 females. This is the control group. The second group also consisted of 120 pupils divided into four sections, out of which 51 male and 69 females. This group was subjected to the experimental way of teaching and thus represents the experimental group. Results show the changes in pupils’ motivational characteristics under the influence of innovative educational content that are reflected through their activities and final attitudes on the physical education value. The discriminate analysis revealed the statistically important differences between pupils that are treated by the experimental program compared to students treated by traditional program in terms of motivation in physical education classes (PE classes. However, the study, in some way, solves the problem of inactivity and pupils’ lack of interest for the PE classes, i.e. it suggests the pupils’ possible development of motivation for work using the appropriate educational contents.

Intrinsic motivation was higher in the autonomy support group than that in the control group. From an experimental perspective, these findings suggest that the autonomy support was successfully manipulated in the PE classes, which in turn increased the students’ perceived autonomy and intrinsic motivation. Key points The SDT is a relevant theoretical framework for elementary school physical education. Using the quasi-experimental research design, this study is one of the earlies studies supporting that elementary school PE teachers can manipulate the instructional context using the SDT to increase students’ perceived autonomy and intrinsic motivation. Increasing students’ perceived autonomy may not lead to significant changes in other SDT constructs (i.e., amotivation, external regulation, introjected regulation, and identified regulation).

This paper presents a novel compact memory in the processing element (PE) for single-instruction multiple-data (SIMD) vision chips. The PE memory is constructed with 8 × 8 register cells, where one latch in the slave stage is shared by eight latches in the master stage. The memory supports simultaneous read and write on the same address in one clock cycle. Its compact area of 14.33 μm2/bit promises a higher integration level of the processor. A prototype chip with a 64 × 64 PE array is fabricated in a UMC 0.18 μm CMOS technology. Five types of the PE memory cell structure are designed and compared. The testing results demonstrate that the proposed PE memory architecture well satisfies the requirement of the vision chip in high-speed real-time vision applications, such as 1000 fps edge extraction.

"Permission to Speak": A Postcolonial View on Racialized Bodies and PE in the Current Context of Globalization.

Science.gov (United States)

Azzarito, Laura

2016-06-01

The current neoliberal context of schools presents difficult challenges in addressing persistent issues of social inequalities. In this article, first, I argue that because of today's market-driven education, the rise of fitness testing in school physical education (PE) can be seriously detrimental to young people in general and to ethnic-minority young people's embodied identity in particular. Second, I explain how the racialization process circulated by the body-at-risk discourse, sustained by the media, and reproduced by high-stakes testing in PE forces ethnic-minority young people to construct their identities through White eyes, which alienates them from a consciousness of their own identity. Third, I explore the possible uses and pitfalls of Spivak's theoretical notion of "strategic essentialism" to put forward strategies to build a positive image of the "other" while attempting to avoid the erasure of difference. Fourth, I conclude the article by suggesting how Spivak's notion of strategic essentialism can be useful in rethinking current PE fitness practices.

The sources of political orientations in post-industrial society: social class and education revisited.

Science.gov (United States)

Van de Werfhorst, Herman G; de Graaf, Nan Dirk

2004-06-01

This paper studies the impact of social class and education on political orientation. We distinguish the 'old' middle class from a new class of social/cultural specialists. However, the difference in their political orientation may especially be related to the level and field of education; the new middle class is more highly educated and often in fields of study that extensively address social competencies, characteristics independently affecting political outcomes. Analyses on Dutch data showed that education is more important in the prediction of 'cultural' liberal issues than social class. Economically-oriented issues are more strongly affected by social class. This means that interests of the new middle class are served by liberal standpoints relating to a strong government and income redistribution policies, but not relating to cultural issues.

The characterisation of two different degradable polyethylene (PE) sacks

2006-01-01

The compostability of two different polyethylene (PE) products on the UK market under open-windrow composting conditions is explored within this paper. Chemical analysis of the PE bags has established their constituents in order to examine how the PE bags have an increased degradability depending on additives. Weight loss of the two different PE products within open-windrow composting conditions was recorded in order to establish the percentage weight loss as an indication of the degradability of the two products and their relative suitability for open-windrow composting. Scanning electron microscopy (SEM) of the PE products over the composting duration established the degradation processes for the PE products within the compost. These analyses concluded that one of the PE product mixes was more degradable than the other. However, neither product completed degraded within the timeframe of 12-14 weeks generally accepted for open-windrow composting in the UK

One hundred and ten first grade students and their six physical educators participated. Students were pre-, post-, and re-tested both qualitatively and quantitatively on overhand throwing and catching. The Test of Gross Motor Development (Ulrich, 1985 was used for the assessment of qualitative skill performance and the Michigan Educational Assessment Program (MEAP, 1984 for the assessment of quantitative skill performance. Between pre- and post-tests students received an eight lessons unit instruction with emphasis on overhand throwing and catching. A total number of thirty-six students (6 students X 6 schools were selected, andtheir videotaped motor behavior in the lessons was analyzed with the Academic Learning Time ¿ Physical Education (ALT-PE,Parker, 1989. Regression analysis was applied to calculate students´ residual scores of achievement and to enable further data analysis. Correlation analysis between students´ achievement and ALT-PE categories indicated significant relationships between skill acquisition, learning and ALT-PE categories.

There is widespread recognition that physical examination (PE) should be taught in Graduate Medical Education (GME), but little is known regarding how to best teach PE to residents. Deliberate practice fosters expertise in other fields, but its utility in teaching PE is unknown. We systematically reviewed the literature to determine the effectiveness of methods to teach PE in GME, with attention to usage of deliberate practice. We searched PubMed, ERIC, and EMBASE for English language studies regarding PE education in GME published between January 1951 and December 2012. Seven eligibility criteria were applied to studies of PE education: (1) English language; (2) subjects in GME; (3) description of study population; (4) description of intervention; (5) assessment of efficacy; (6) inclusion of control group; and (7) report of data analysis. We extracted data regarding study quality, type of PE, study population, curricular features, use of deliberate practice, outcomes and assessment methods. Tabulated summaries of studies were reviewed for narrative synthesis. Fourteen studies met inclusion criteria. The mean Medical Education Research Study Quality Instrument (MERSQI) score was 9.0 out of 18. Most studies (n = 8) included internal medicine residents. Half of the studies used resident interaction with a human examinee as the primary means of teaching PE. Three studies "definitely" and four studies "possibly" used deliberate practice; all but one of these studies demonstrated improved educational outcomes. We used a non-validated deliberate practice assessment. Given the heterogeneity of assessment modalities, we did not perform a meta-analysis. No single strategy for teaching PE in GME is clearly superior to another. Following the principles of deliberate practice and interaction with human examinees may be beneficial in teaching PE; controlled studies including these educational features should be performed to investigate these exploratory findings.

2017-11-01

Full Text Available IntroductionAs physical performance may be more difficult for overweight children than for their non-overweight peers, understanding how weight impacts student performance in the physical education (P.E. classroom could inform school-based obesity prevention programming.Materials and methodsThis qualitative case study examined one elementary physical educator’s perspectives of overweight students’ weight-related experiences in her classroom. Narratives were elicited during an in-depth interview and analyzed using structural and thematic analyses. We utilized the social cognitive theory to inform our exploration of the narratives.FindingsThe thematic analysis illuminated a behavioral pattern of student refusal to participate in the P.E. classroom while the structural analysis emphasized the teacher’s constructive, individualized responses to participation refusals. Combined, the two analytic techniques provided a more holistic snapshot of the experiences of overweight students in this elementary school. In addition, a preliminary model explaining the behavioral pattern among overweight students in this particular P.E. classroom was created.DiscussionStudents who were overweight were more likely to initially refuse to attempt physical tasks in the classroom because they feared peer ridicule, and the teacher played a critical role in whether these students chose to participate in subsequent classes. As agents of change, P.E. educators should be included in formative stages of comprehensive, systemic changes to combat childhood obesity.

Rahkonen Ossi

2010-04-01

Full Text Available Abstract Background Physical inactivity has become a major public health problem and clear educational differences in physical activity have been reported across Europe and USA. The origins of adulthood physical activity are suggested to be in childhood and adolescence physical activity. Hardly any studies have, however, examined if the educational differences in physical activity might also be due to educational differences in early experiences in physical activity. Thus, our aim was to examine how competitive sports in youth, and exercise in late adolescence, and opinions on physical education (PE in childhood determined adulthood leisure-time physical activity (LTPA in different educational groups. Methods We used cross-sectional population-based National FINRISK 2002 data for 1918 men and 2490 women aged 25 to 64 years. Competitive sports in youth, exercise in late adolescence, and opinions on PE in childhood were assessed retrospectively via self-reports. Adulthood LTPA was collected with 12-month recall. In 2008, we calculated structural equation models including latent variables among the low- ( Results Men more often than women reported that their experience of PE was interesting and pleasant as well as having learned useful skills during PE classes. Men, compared to women, had also been more active in the three selected competitive sports in youth and exercised in late adolescence. Participation in competitive sports in youth among the low-educated and exercise in late adolescence among the high-educated had a direct effect on adulthood LTPA. Among the low-educated, opinions on PE in childhood had an indirect effect on adulthood LTPA through participation in competitive sports in youth whereas among the high-educated, the indirect effect went through exercise in late adolescence. The effects were mainly similar between genders. Conclusions Our study answers to a strong need to assess the determinants of leisure-time physical activity to

Educating Students for a Lifetime of Physical Activity: Enhancing Mindfulness, Motivation, and Meaning.

Science.gov (United States)

Ennis, Catherine D

2017-09-01

For many years, pedagogical scholars and physical education (PE) teachers have worked to enhance effective teaching and learning environments. Yet for some children, youth, and young adults, many of the benefits associated with a physically active lifestyle remain elusive. Enhancing programming and performance to meet physical activity goals may require moving programs beyond "effective." It will require teachers and program leaders to focus programmatic attention on strategies to actually increase students' out-of-class physical activity behavior. Transformative PE provides physical activity content within a nurturing and motivating environment that can change students' lives. It focuses on PE students' role in cognitive decision making, self-motivation, and their search for personal meaning that can add connection and relevance to physical activities. In this SHAPE America - Society of Health and Physical Educators Research Quarterly for Exercise and Sport Lecture, I have synthesized the research on these topics to emphasize useful findings applicable to teachers' everyday planning and teaching. Using sport, physical activity, dance, and adventure activities as the means to an end for personal and social growth, we can meet our commitment to effective standards-based education while preparing students for a lifetime of physical activity.

RS3PE syndrome (Remitting Seronegative Symmetrical Synovitis with Pitting Edema Syndrome) is one of the disorders which present as polyarthritis. It is important to be aware of RS3PE syndrome when encountering elderly patients with polyarthritis who are negative for rheumatoid factor. We report 4 cases of RS3PE syndrome. All cases shared common clinical findings, such as acute onset, symmetrical polyarthritis, pitting edema of the hands and feet, and being negative for rheumatoid factor in serum. Treatment with corticosteroid was very effective in all cases. However, two patients showed a deteriorated clinical condition during the tapering of corticosteroid. Corticosteroid should be tapered off cautiously in patients with RS3PE syndrome. (author)

CosmoAcademy is a part of the CosmoQuest mission to educate the public about astronomy, planetary science, and similar subjects. Through short-duration online classes with small enrollment, we can cover many subjects of interest to the interested layperson, taught by experts. Typical CosmoAcademy classes consist of four hours of face-to-face time, and are limited to fewer than 20 students. This is in contrast to massive online classes such as MOOCs, which often replicate typical university courses, but which rarely allow student-instructor interaction. Additionally, we offer continuing-education classes for classroom teachers and other educators on similar subjects, to let them enrich their own teaching. WeBecause of the short classes, we can offer short classes both on standard topics (the Solar System planets, introduction to cosmology) and specific subjects relating to the news (LIGO, asteroid missions). The expert instructors may be graduate students, research professionals, or anyone with the technical background. We also offer classes to train instructors before they begin teaching. These professional development classes are designed to help those without classroom experience, but also support those who To make that work, we offer classes to train the instructors before they begin teaching, if they don't have the experience or just want to learn how to be more effective in the classroom.We will present CosmoAcademy's program, and explain what it offers both to people taking the class and those who might want to teach with us.

Highlights: • Successful modeling of gas mixtures and droplet flows in multicompartment system. • For pressure, modeling of gas-wall heat transfer (and heat radiation) is important. • Dependence of gas mixing time in spray vessel on the used nozzle may be essential. • Penetration of helium-enriched mixture into another vessel due to spray operation. • Effect on pressure of sump re-evaporation and gas heating (by walls) during spray. - Abstract: The ERCOSAM project (together with the SAMARA project) includes a set of multi-stage experiments carried out at different thermal-hydraulics facilities (TOSQAN, MISTRA, PANDA, SPOT) and their numerical simulation. The test sequences aim to investigate hydrogen concentration build-up and stratification during a postulated severe accident as well as the effect of activation of Severe Accident Management systems (SAMs) on stratification. At the initial Phases I–III of the tests stratification of the injected light gases (steam, helium) is established, pressure increases. The models of SAMs are activated at the final Phase IV. In the paper, two spray tests PE1 and PE2 performed at PANDA facility are numerically investigated aiming for code validation (FLUENT) and better understanding of physical processes. Phases I–IV of the tests were simulated. A satisfactory agreement with the experimental results on gas component mole fractions was obtained. The reasons of obtained some discrepancies in pressure and temperature were studied in multivariate calculations and discussed in the paper. The tests PE1 and PE2 were performed with different spray nozzles and initial conditions. In simulation that resulted in different flow patterns during spray operation. The sensitivity to nozzle angle and some other input parameters was investigated. Possible factors of depressurization rate caused by spray operation were also studied. The key features observed in the experiments and obtained numerically being of interest in terms of

2015-01-01

Although researchers have demonstrated the importance of interpersonal processes in school-based physical education (PE), there have been calls for further studies that account for multiple relational perspectives and provide a more holistic understanding of students' relational perceptions. Guided by principles outlined within self-determination theory and the tripartite efficacy model, our aim was to explore the ways in which students' perceptions about their teacher and classmates directly and/or indirectly predicted motivation, anxiety, and engagement in PE. A total of 374 female high-school students reported the extent to which their teachers and classmates independently (a) engaged in relatedness-supportive behaviors, (b) satisfied their need for relatedness, and (c) were confident in their ability in PE (i.e., relation-inferred self-efficacy). Students also rated their motivation and anxiety regarding PE, and teachers provided ratings of in-class behavioral engagement for each student. Analyses demonstrated support for the predictive properties of both teacher- and peer-focused perceptions. Students largely reported more positive motivational orientations when they held favorable perceptions regarding their teacher and peers, and autonomous motivation was in turn positively related to behavioral engagement ratings. These findings offer novel insight into the network of interpersonal appraisals that directly and indirectly underpins important in-class outcomes in PE.

Although researchers have demonstrated the importance of interpersonal processes in school-based physical education (PE), there have been calls for further studies that account for multiple relational perspectives and provide a more holistic understanding of students’ relational perceptions. Guided by principles outlined within self-determination theory and the tripartite efficacy model, our aim was to explore the ways in which students’ perceptions about their teacher and classmates directly and/or indirectly predicted motivation, anxiety, and engagement in PE. A total of 374 female high-school students reported the extent to which their teachers and classmates independently (a) engaged in relatedness-supportive behaviors, (b) satisfied their need for relatedness, and (c) were confident in their ability in PE (i.e., relation-inferred self-efficacy).

Full Text Available Over the past decade, a number of methods have been developed to estimate size-class primary production from either in situ phytoplankton pigment data or remotely-sensed data. In this context, the first objective of this study was to compare two methods of estimating size class specific (micro-, nano-, and pico-phytoplankton photosynthesis-irradiance (PE parameters from pigment data. The second objective was to analyse the relationship between environmental variables (temperature, nitrate and PAR and PE parameters in the different size-classes. A large dataset was used of simultaneous measurements of the PE parameters (n = 1,260 and phytoplankton pigment markers (n = 2,326, from 3 different institutes. There were no significant differences in mean PE parameters of the different size classes between the chemotaxonomic method of Uitz et al. (2008 and the pigment markers and carbon-to-Chl a ratios method of Sathyendranath et al. (2009. For both methods, mean maximum photosynthetic rates (PmB for micro-phytoplankton were significantly lower than those for pico-phytoplankton and nano-phytoplankton. The mean light limited slope (αB for nano-phytoplankton were significantly higher than for the other size taxa. For micro-phytoplankton dominated samples identified using the Sathyendranath et al. (2009 method, both PmB and αB exhibited a significant, positive linear relationship with temperature, whereas for pico-phytoplankton the correlation with temperature was negative. Nano-phytoplankton dominated samples showed a positive correlation between PmB and temperature, whereas for αB and the light saturation parameter (Ek the correlations were not significant. For the Uitz et al. (2008 method, only micro-phytoplankton PmB, pico-phytoplankton αB, nano- and pico-phytoplankton Ek exhibited significant relationships with temperature. The temperature ranges occupied by the size classes derived using these methods differed. The Uitz et al. (2008 method

Full Text Available Framed within Self-Determination Theory, the purpose of the present study was to test the effects of a training program with physical education (PE teachers. Participants were 21 high school PE teachers (experimental group, n = 10; control group, n = 11, and their 836 students, aged 12 to 16 years. Teachers in the experimental group received a training program consisting of strategies to support autonomy, competence, and relatedness need satisfaction. A repeated measures ANCOVA was carried out for each dependent variable. After the intervention, students in the experimental group significantly increased their scores on autonomy support, relatedness support, autonomy satisfaction, autonomous motivation, controlled motivation, and intention to be physically active, as compared to the control group. These findings emphasize the utility of a training program with PE teachers to promote the students' psychological need satisfaction, and hence, self-determined motivation toward PE classes.

Physical education (PE) programs aim to promote physical activity (PA) and reach most school-aged youth. However, PA levels within PE lessons are often low. In this cluster-randomized controlled trial, we examined the effects of three self-determination theory-based motivational strategies on PA and sedentary behavior, as well as their hypothesized antecedents during PE lessons. Data were collected in Sydney, Australia (October-December 2011). After baseline testing, teachers (n=16) and their classes (n=288 students; M=13.6 years, 50.4% male) were randomly assigned to one of four teaching strategy conditions: (1) explaining relevance; (2) providing choice; (3) complete free choice; or (4) usual practice. Teachers then delivered the assigned strategy. Primary outcomes were accelerometer-assessed PA and student motivation during lessons. Secondary outcomes included sedentary behavior, perceptions of teachers' support and psychological needs satisfaction. The 'free choice' intervention increased PA (pmotivation, but students' autonomy increased during both choice-based interventions (p<.05). Promoting choice can produce short-term increases in PA and decreases in sedentary behavior, as well as increased perceived autonomy during PE lessons. © 2013.

Wang Huiliang; Wang Chun; Chen Wenxiu

2001-01-01

In order to find the major reason for the radiation discoloration of PE, the changes of yellow index (YI) of HDPE and LDPE under γ irradiation in air or N 2 and after irradiation are measured using colorimeter. The growth and decay of alkyl free radical formed in HDPE and LDPE, and the change of the absorbance of conjugated double bonds formed in PE are measured using ESR and UV-Visible spectrometer. The YI of HDPE is higher than that of LDPE at the same radiation dose. The YI of PE irradiated in air is higher than that of PE irradiated in N 2 at the same radiation dose. The YI of PE irradiated different dose decreases with post-irradiation storage time firstly, up to a certain time, it becomes stable. It is found that the formation and decay of free radicals is very similar to that of the change of YI, whereas, the change of the absorbance of conjugated double bonds formed in PE is different to the change of YI. The results are discussed, it is believed that the major reason for the radiation discoloration is the formation of trapped free radicals

To analyze the association between physical activity, participation in Physical Education classes, and indicators of social isolation among adolescents. This was an epidemiological study based on secondary analysis of data from a representative sample of students (14-19 years) from public high schools (n=4,207). Data were collected through the questionnaire Global School-based Student Health Survey. The independent variables were the level of physical activity and enrollment in Physical Education classes, while the dependent variables were two indicators of social isolation (feeling of loneliness and having few friends). Descriptive and inferential procedures were used in the statistical analysis. Most of the adolescents were classified as insufficiently active (65.1%) and reported not attending Physical Education classes (64.9%). Approximately two in each ten participants reported feeling of loneliness (15.8%) and, in addition, about one in each five adolescents reported have only one friend (19.5%). In the bivariate analysis, a significantly lower proportion of individuals reporting social isolation was observed among adolescents who referred higher enrollment in Physical Education classes. After adjustment for confounding variables, binary logistic regression showed that attending Physical Education classes was identified as a protective factor in relation to the indicator of social isolation 'having few friends,' but only for girls. It was concluded that participation in Physical Education classes is associated with reduced social isolation among female adolescents. Copyright © 2015 Sociedade Brasileira de Pediatria.

The goal of this study was to develop and evaluate a complementary cyber education program for a required pathophysiology class for nursing students. The cyber education program comprised electronic bulletin boards, correspondence material storage, an announcement section, a report submission section, reference sites, and statistics on learning rates. Twelve online lectures complemented five lectures in the classroom. To evaluate the course's educational effectiveness, we performed an online objective questionnaire and an open questionnaire survey anonymously, and compared the complementary cyber education program with traditional classroom education. The complementary cyber education program effected significant improvements in scores for importance with regard to major, clarity of goals and education plans for courses, professor readiness, preciseness and description of lectures, amount and efficiency of assignments, and fairness in appraisal standards compared with the traditional classroom education group. This study indicates that a complementary cyber education program provides nursing students with the flexibility of time and space, the newest information through updated lectures, efficient motivational aids through intimacy between the lecturer and students, and concrete and meaningful tasks. The complementary cyber education course also increased student effort toward studying and student satisfaction with the class.

Belek, I

2000-02-01

The aim of this study is to determine the separate effects of social class, income, education and area of residence on psychological distress. The study also assesses whether the association between prevalence of high score on the 12-item General Health Questionnaire (GHQ 12) and social class is independent of other variables. Psychological distress was assessed by means of the GHQ 12. The study covered 1,092 adults aged 15 years or more living in two different quarters of Antalya. Social class status was defined by occupational position, with income, education and area of residence treated as confounders. Chi-square and logistic regression analyses were used to evaluate the data. Large inequalities in psychological distress by all variables were observed. Psychological distress was significantly associated with class status, after adjusting for income, education, area of residence and other potential confounders (age, sex and marital status). Class inequalities in psychological distress were observed between blue-collar workers/unqualified employees and bourgeoisie. These findings support the view that the recent widening of inequalities among social classes in Turkey pose a substantial threat to health.

Standage, Martyn; Duda, Joan L; Ntoumanis, Nikos

2006-03-01

In the present study, we used a model of motivation grounded in self-determination theory (Deci & Ryan, 1985, 1991; Ryan & Deci, 2000a, 2000b, 2002) to examine the relationship between physical education (PE) students' motivational processes and ratings of their effort and persistence as provided by their PE teacher. Data were obtained from 394 British secondary school students (204 boys, 189 girls, 1 gender not specified; M age = 11.97 years; SD = .89; range = 11-14 years) who responded to a multisection inventory (tapping autonomy-support, autonomy, competence, relatedness, and self-determined motivation). The students' respective PE teachers subsequently provided ratings reflecting the effort and persistence each student exhibited in their PE classes. The hypothesized relationships among the study variables were examined via structural equation modeling analysis using latent factors. Results of maximum likelihood analysis using the bootstrapping method revealed the proposed model demonstrated a good fit to the data, chi-squared (292) = 632.68, p self-determination. Student-reported levels of self-determined motivation positively predicted teacher ratings of effort and persistence in PE. The findings are discussed with regard to enhancing student motivation in PE settings.

Full Text Available this article tries to know the relationships that can be found between School Physical Education and Leisure Physical Sportive Practice among the population of teenagers and young people from Huesca who study Compulsory Secondary Education, Bachillerato, Professional Studies, taking into account the gender. In this research, the satisfaction level referred to the experienced physical education lessons is expressed through the level of benefit that is assigned to those experiences when young people start extracurricular physical-sportive practice. Among the main conclusions, it is checked that poorly one out three of students from Huesca, states that physical education lessons were useful to access extracurricular practice. As well, the consideration that physical education lessons are a way to access to extracurricular physical-sportive practice is mainly associated to women. The more useful are the lived experiences during P.E. lessons, the more is the number of feminine students who go on practicing and less is the number of people that give up sport. In fact, seven out of ten of feminine students who refer to these lessons as very useful, keep on practicing and three of them abandon physical activity. This relationship is not established taking about masculine genre.

The polyethylene(PE) pipes are widely used to transport city gas worldwide with steel pipes. Generally, Steel pipe are used for high pressure line and PE pipe for low pressure line whose pressure is less than 4 kg/m 2 . The steel pipe line are subject to 100 percent Radiographic Testing(RT) during installation stage, on the contrary, there has been no the established testing method for the welding fusion joint of polyethylene pipes, so all quality control is limited only Visual Testing(VT) or management of Fusion welding equipment. Even though PE pipeline is exposed to lower pressure than steel pipeline, the gas leakage from PE pipe may result in almost the same serious consequence from steel pipeline. So, it is necessary to develop the reliable testing standard for PE pipeline from the point of view of NDT engineers.

Polyethylene (PE) was irradiated with 63 keV Ar + ions to the fluences from 1x10 12 to 3x10 15 cm -2 and then grafted at room temperature from water solution with amino acids (alanine, leucine). Using various spectroscopic techniques (UV-VIS, FTIR, RBS and EPR) it was shown that the amino acids penetrate into PE where they are eventually captured either on double bonds or on free radicals created by the ion irradiation. Grafting with amino acids in the whole specimen layer modified by irradiation is observed. The ion-beam-modified and amino-acid grafted PE is supposed to exhibit increased biocompatibility. (author)

Scintigraphic evidence for overdiagnosis of small PE on CT pulmonary angiography

International Nuclear Information System (INIS)

Lu, Yang

2017-01-01

A 68-year-old man with recent history of a fall presented with dyspnea on exertion, and underwent computed tomography pulmonary angiography (CTPA) for possible pulmonary embolism (PE). The CTPA was first read by the radiology resident as nondiagnostic for segmental PE. Subsequent planar perfusion (Q) images were normal; meanwhile, the attending radiologist revised the CTPA results as subsegmental PE in the left upper lobe. Further Q-SPECT images were obtained and fused with CTPA for clarification, which showed normal perfusion in the region of PE. The patient was monitored without anticoagulation treatment and remained uneventful for 12 months. This case illustrates that CTPA can lead to overdiagnosis and overtreatment of nonocclusive subsegmental PE

Polyethylene (PE) is widely used to make bulk containers in rotational molding process. The challenge in this study is to improve permeation resistance of PE to hydrocarbon solvents and gases. Adding organomodified clay improves the thermal, barrier and mechanical properties of PE. In fact, clay layers create a tortuous path against the permeant, yielding better barrier properties. Due to the non-polar hydrophobic nature of PE and polar hydrophilic structure of clay minerals, the compatibilizer plays a crucial role to enhance the dispersion level of clay in the matrix. In this study High Density Polyethylene (HDPE) and Linear Low Density Polyethylene (LLDPE) layered silicate nanocomposite were melt-compounded with two concentrations of organomodified clay (2 and 4 wt. %). The interaction between nanoclay, compatibilizer and rotomolding grade of PE were examined by using X-ray diffraction, transmission electron microscopy (TEM) and rheology test. Rheology was used to determine the performance of our material at low shear processing condition.

Polyethylene (PE) surface was treated with Ar plasma. Activated surface was grafted from methanol solution of 1,2-ethanedithiol. Then the sample was immersed into freshly prepared colloid solution of Au-nanoparticles. Finally Au layer was sputtered on the samples. Properties of the modified PE were studied using various methods: AFM, EPR, RBS and nanoindentation. It was shown that the plasma treatment results in degradation of polymer chain (AFM) and creation of free radicals by EPR. After grafting with dithiol, the concentration of free radicals declines. The presence of Au and S in the surface layer after the coating with Au-nanoparticles was proved by RBS. Plasma treatment changes PE surface morphology and increases surface roughness, too. Another significant change in surface morphology and roughness was observed after deposition of Au-nanoparticles. Nanoindentation measurements show that the grafting with Au-nanoparticles increases adhesion of subsequently sputtered Au layer.

Full Text Available Democracy depends on the participation of citizens. Citizenship educationis taking place in classroom communities to prepare pupils for their role ascitizens. Class councils are participatory forms of citizenship educationguaranteeing the children’s right to form and express their views freely aswritten down in the Convention on the Rights of the Child. Theoreticaldeficiencies and empirical objections have been formulated againstparticipation in the school setting. Despite widespread practices, empiricaldata about class councils in Switzerland barely exists. In our researchproject we video-recorded fourteen class councils in secondary schools, weinterviewed the teacher and four pupils of each class, and all the pupilsfilled in a standardized questionnaire. Class councils are very popular formsof education with pupils although the actual power to influence decisions bydeliberation is doubted to some extent. Quantitative analysis of the videorecordingsshows the wide range of forms of class councils that exist inrespect to the talking time of the pupils. To express one’s own viewpointand to understand the standpoint of other discussants, constructarguments and counterarguments, participate, and lead discussions aredifficult tasks. Based on the empirical research the project describes threeforms of class councils that differ in the degree of favouring thedevelopment of communicative competences as a part of citizenshipeducation.

Empowering children with special educational needs to speak up: experiences of inclusive physical education.

Science.gov (United States)

Coates, Janine; Vickerman, Philip

2010-01-01

The inclusion of children with special educational needs (SEN) has risen up the political agenda since the return of the Labour Government in 1997. This has seen increasing numbers of children with SEN being educated within mainstream schools. This study examines the perspectives of children with SEN attending both mainstream and special schools in relation to their experiences of physical education (PE). Findings demonstrate that children with SEN in both mainstream and special schools enjoy PE, although issues were raised in mainstream schools regarding bullying and the appropriateness of activities in PE lessons. The findings show how children offered suggestions about how to improve PE and make it more beneficial. The findings identify how children are empowered through consultation, and are aware of their needs and abilities. As such it is evident that schools and those supporting inclusive physical activity for children with SEN must use consultation as a tool for empowering pupils as a means of providing them with choices while gaining a rich insight into their lived experiences of PE.

The lack of analytical methods specific for each lipid class, particularly for phospholipids and sphyngolipids, makes necessary their separation by preparative techniques before quantification. LC-MS would be the election method but for daily work in the clinical laboratory this is not feasible for different reasons, both economic and time consuming. In the present work, we have optimized an HPLC method to quantify lipid classes in plasma and erythrocytes and applied it to samples from patients with cirrhosis. Lipid classes were analyzed by normal phase liquid chromatography with evaporative light scattering detection. We employed a quaternary solvent system to separate twelve lipid classes in 15 min. Interday, intraday and recovery for quantification of lipid classes in plasma were excellent with our methodology. The total plasma lipid content of cirrhotic patients vs control subjects was decreased with diminished CE (81±33 vs 160±17 mg/dL) and PC (37±16 vs 60±19 mg/dL). The composition of erythrocytes showed a decrease in acidic phospholipids: PE, PI and PS. Present methodology provides a reliable quantification of lipid classes in blood. The lipid profile of cirrhotics showed alterations in the PC/PE plasma ratio and in the phospholipid content of erythrocytes, which might reflect alterations in hepatocyte and erythrocyte membrane integrity.

Full Text Available A retrospective study was made of sports injuries occurring in physical education classes in 51 junior and senior high schools in Israel during a period of 14 months (2000-2002. The survey covered a total population of 11439 students aged 12 to 18, 52% male, 48% female. The aim of the study was to assess the incidence, types and risk factors involving sports injuries among students in physical education classes. Physical education teachers were asked to complete questionnaires recording injuries that occurred during their lessons. Data included: socio-demographic parameters (gender, age, height and weight of the injured students, area and type of injury, time of injury during the class, type of sport activity, previous injuries, assessment of sport capabilities and performance. A total of 192 injuries were recorded in the survey (1.70%. Male and female students had fairly similar injury rates (49% female, 51% male. 12-14 year old students showed the greatest number of injuries (52%. The ankle was the most common site of injury in both genders (48% mostly involving ankle sprain. Athletics was the most common sport involving injury (38%. 45% of injuries were reported to occur in the start of the class, whereas 26% of injuries were repeat injuries. This survey showed that the incidence of injuries during supervised physical education classes in high schools in Israel is relatively low and is similar to that of other Western countries.

Full Text Available Participation in physical education classes is a complex issue; many factors lead students to participate in classroom activities in different ways. This research examines how the way to take part in the class is influenced by experiences outside of school. In this way, seeks to analyze how the actions and family discourses influence the different interests of girls and boys, such as the participation in physical activities outside of school. Also, examines the influence of the participating inside of the school, and how expectations and understandings of bodily practices for boys and girls influence different ways to participate in classes when comparing the male and female gender. For this, held semi-structured interviews and classroom observations into four groups of the eighth year of two public schools in the city of Campinas-SP. The notes of this research indicated that the experience and knowledge of the body and body practice outside of school have the big influence on the ways of participating in classes. The cultural environment of the students gave different experiences and understandings for boys and girls in the knowledge that circulate in physical education classes and contributed in different ways to participate in class.

Segregation to grain boundaries in nimonic PE16 superalloy

International Nuclear Information System (INIS)

Nettleship, D.J.; Wild, R.K.

1990-01-01

Nimonic PE16 alloy is a nickel-based superalloy containing 34 wt.% iron and 16wt.% chromium with additions of molybdenum, titanium and aluminium. It is used in the fuel assembly of the UK advanced gas-cooled reactors (AGR). This component supports significant loads in service and its mechanical integrity is therefore of paramount importance. Mechanical properties may be influenced by the grain size and grain boundary composition, both of which can themselves alter during service. Scanning Auger microscopy is a well-established method for investigating grain boundaries, and has now been applied to the study of PE16. In order to expose PE16 grain boundary surfaces it is necessary to hydrogen charge samples and fracture by pulling in tension at a slow strain rate within the ultra-high vacuum chamber of the Auger microprobe. A series of casts of nimonic PE16 alloy that have received a range of thermal ageing treatments have been fractured in an intergranular manner and the grain boundary composition determined. Segregation of trace and minority elements, particularly Mo and P, has been detected at grain boundaries. Significant variations between different as-manufactured casts were observed, whilst ageing brought about the growth of chromium-rich particles on the grain boundaries. Ductile fracture in PE16 followed a path through Ti(C, N) particles. Many of these particles incorporated large amounts of sulphur. (author)

Magnetic and electrostatic fluctuations have been measured at the short scale length of the collisionless skin depth (c/ω pe using small magnetic and electrostatic probes in the Tokapole II tokamak. For certain conditions and at high frequency (MHz range) the amplitude is observed to increase as wavelength is decreased toward the c/ω pe scale. Wavelength dependence is inferred from measurements with probes of varying sizes. The amplitude of the turbulence at the c/ω pe scale is smaller than the dominant low frequency turbulence, and is thus not relevant to transport in Tokapole II. Comparison with theoretical treatments of c/ω pe turbulence is discussed

Full Text Available Physical Education (PE as new profesion based on physical activity entered in Slovenian and south slavic millieu in the second half of 19 th century. The roots are in gymnastic societies and paralelly in school system. In austrian part of Habsburg Empire in 1869 new school's law was adopted. It proclaimed 2 obligatory hours of PE. With institunalization of PE soon arrised the problem of profesional PE staff and opened the question of profesional physical educational courses or even study for PE trainers and teachers. The problem was firstly solving or by gymnastic courses or later with establishment of special high schools for physical education. In Slovenia important steps in solving the PE profesional problem were done after the second world war by organising new PE study. Despite stereotypes of nonacademism or nonscientism PE gained political and social suport and in the fithtieth of 20. Century Institut for PE was established. Institut was the begginer of High School for Physical Culture, established in 1960. The purpose of new School was to educate and prepare profesionals of PE for the needs of school system and civil-society. On the other side, the establishmet meant also the start of new science – kinesiology. In the paper we will on the basis of sources focused on cruical steps in the process of the educational institutionalization of PE and formation of Faculty of Sport, which in 2010 celebrated its 50 th anniversary.

The state of health in children and adolescents during the time of education in secondary schools is getting worse: the prevalence rate of functional disorders and chronic diseases is increasing. There was executed the assessment of the overwroughtness of the training-education process in secondary school institutions. The prior characteristics of the educational activity are: intellectual, sensory, emotional loads; their monotony and mode of educational activity, school work intensity. The system of indices of the overwroughtness of the education labour was formed with account ofpsycho-physiological characteristics of children's organism. There was performed the research of the overwroughtness of educational activity in 820 schoolchildren. The overwroughtness of the educational process was evaluated on the basis of chronometry research, questionnaire survey of teachers and parents, and with taking into account the organization of educational process. In questionnaire survey there were involved 52 teachers and 389 parents. The assessment of overwroughtness factors of the educational activity was carried out in 5-10th classes for academic disciplines: Russian Language, Literature, Mathematics, History, Geography, Foreign Languages. It was found that the characteristics of "mental load" in schoolchildren are established to be the one of the main limiting factors that allow to refer training activities to "overwroughted of first degree" (3.1 class). Sensory loads on the studied academic subjects are rated as the second class of overwroughtness and are "permissible." The monotony of loads was revealed to correspond to 1st and 2nd class of overwroughtness and is therefore an optimal or acceptable. Training activities in the traditional educational institution corresponds to the 2nd class of overwroughtness - "permissible." The arduousness of the educational process in an innovative school is rated as the third class of the first degree ofthe overwroughtness (3

2010-05-01

Polybrominated diphenyl ethers (PBDEs) are flame retardants widely used in many everyday products such as cars, furniture, textiles, and other electronic equipment. The commercial PBDEs have three major technical mixtures: penta-(PeBDE), octa-(OBDE) and decabromodiphenyl ethers (DeBDE). PeBDE is a mixture of several BDE congeners, such as BDE-47, -99, and -100, and has been included as a new member of persistent organic pollutants (POPs) under the 2009 Stockholm Convention. In order to produce gridded emission inventories of PeBDE on a global scale, information of production, consumption, emission, and physiochemical properties of PeBDE have been searched for published papers, government reports, and internet publications. A methodology to estimate the emissions of PeBDE has been developed and global gridded emission inventories of 2 major congener in PeBDE mixture, BDE-47 and -99, on a 1 degree by 1degree latitude/longitude resolution for 2005 have been compiled. Using these emission inventories as input data, the Canadian Model for Environmental Transport of Organochlorine Pesticides (CanMETOP) model was used to simulate the transport of these chemicals and their concentrations in air were calculated for the year of 2005. The modeled air concentration of BDE-47 and -99 were compared with the monitoring air concentrations of these two congeners in the same year obtained from renowned international/national monitoring programs, such as Global Atmospheric Passive Sampling (GAPS), the Integrated Atmospheric Deposition Network (IADN), and the Chinese POPs Soil and Air Monitoring Program (SAMP), and significant correlations between the modeled results and the monitoring data were found, indicating the high quality of the produced emission inventories of BDE-47 and -99.

The effect of outdoor environmental education on in-class behaviors of sixth, seventh and eighth grade students

Science.gov (United States)

Cumberbatch, Albert R.

Does the natural environment enhance positive human behaviors, behaviors which meet societal expectations? If that is the case, at what level of our social development does exposure and involvement with nature become a prerequisite? This study sought to discover an answer to the first question through examination of a small public school sample. The second will have to await future study. Public schools, while making some token response to the rising environmental consciousness, have failed or completely ignored environmental education. This study focuses on using the natural environment as a classroom with an environmental education curriculum. The control was academic grades before the environmental education class. The independent variable was academic grades after environmental education. Comparisons of academic conduct grades between classes taken before and after environmental education were made. Three environmental education classes comprising ninety students were evaluated. The mean of all classes was calculated. Results indicate that there is a positive behavioral correlation between environment education and academic classes. However, there were many uncontrolled variables which necessitate further study. One example is the arbitrary standard among teachers for evaluating conduct grades. Conduct grades can also be subjective. In further studies, a standardized tool for evaluating conduct grades would be essential.

A group-level approach to analyzing participative ergonomics (PE) effectiveness: The relationship between PE dimensions and employee exposure to injuries.

Science.gov (United States)

Morag, Ido; Luria, Gil

2018-04-01

Most studies concerned with participative ergonomic (PE) interventions, focus on organizational rather than group level analysis. By implementing an intervention at a manufacturing plant, the current study, utilizing advanced information systems, measured the effect of line-supervisor leadership on employee exposure to risks. The study evaluated which PE dimensions (i.e., extent of workforce involvement, diversity of reporter role types and scope of analysis) are related to such exposure at the group level. The data for the study was extracted from two separate computerized systems (workforce medical records of 791 employees and an intranet reporting system) during a two-year period. While the results did not confirm the effect of line-supervisor leadership on subordinates' exposure to risks, they did demonstrate relationships between PE dimensions and the employees' exposure to risks. The results support the suggested level of analysis and demonstrate that group-based analysis facilitates the assimilation of preventive interventions. Copyright © 2017 Elsevier Ltd.

Normal birth has long been promoted by Lamaze International in its mission and vision statements and by the Lamaze Institute for Normal Birth. The Official Lamaze Guide: Giving Birth with Confidence, a book by Judith Lothian and Charlotte DeVries, can be used by birth educators to alter the focus from learning what to expect when one fears the worst to empowering women to understand that birth is usually a healthy, normal process. In this column, the author suggests ways in which childbirth educators can use The Official Lamaze Guide in their classes. PMID:17541460

Lived experiences of nurse educators on teaching in a large class at a nursing college in Gauteng

Directory of Open Access Journals (Sweden)

Maria G. Ndawo

2016-07-01

Full Text Available Background: The gradual increase in the number of learners admitted into a nursing college in Gauteng resulted in an increase in class size without a proportional increase in the number of nurse educators. Objectives: To explore and describe the experiences of nurse educators teaching in large classes at a nursing college in Gauteng in order to present recommendations to facilitate teaching and learning. Method: A qualitative, exploratory, descriptive, and phenomenological research design which is contextual in nature was used. A total of 20 nurse educators were selected through purposive sampling, and in-depth phenomenological semi-structured individual interviews were conducted between January and February 2013. Data were analysed together with the field notes, using Tesch’s open coding protocol of qualitative data analysis. Lincoln and Guba’s four principles were used to ensure trustworthiness. Results: The themes that emerged from this study were that nurse educators experienced difficulty in recognising learners as individuals in a large class, using innovative pedagogical strategies, and managing a large class. These findings had a negative impact on meaningful teaching and learning as they interfered with an enabling learning environment. Recommendations: Nurse educators should be empowered with facilitative skills in order to effectively manage a large class and hence to achieve teaching and learning abilities. Conclusion: There is a need for nurse educators to finding alternative ways to overcome challenges associated with teaching in large classes and prepare learners to render individualised, caring and holistic nursing care to each unique patient in the healthcare setting. Keywords: Large class, Teaching, Learning; Hindrance

To explore whether there are differences in the concentration of the secretogranin II-derived peptide secretoneurin and the chromogranin B-derived peptide PE-11 between the healthy and inflamed human dental pulps. Furthermore, colocalization studies with calcitonin gene-related peptide were performed to confirm the sensory origin of the peptidergic nerves in the dental pulp. The concentrations of secretoneurin and PE-11 were determined by highly sensitive radioimmunoassays in extracts of dental pulps, the molecular form of secretoneurin immunoreactivities by RP-HPLC with subsequent radioimmunoassay and colocalization studies with calcitonin gene-related peptide were performed by double immunofluorescence. Only secretoneurin but not PE-11 was detectable by radioimmunoassays whereas nerve fibers could be made visible for both secretoneurin and PE-11. Furthermore, there was a full colocalization of secretoneurin and PE-11 with calcitonin gene-related peptide in immunohistochemical experiments. There were no differences in the concentration of secretoneurin between the healthy and inflamed human dental pulp and moreover, the characterization of the secretoneurin immunoreactivities revealed that only authentic secretoneurin was detected with the secretoneurin antibody. There is unequivocal evidence that secretoneurin and PE-11 are constituents of the sensory innervation of the human dental pulp and although not exclusively but are yet present in unmyelinated C-fibers which transmit predominantly nociceptive impulses. Secretoneurin might be involved in local effector functions as well, particularly in neurogenic inflammation, given that this is the case despite of unaltered levels in inflamed tissue.

Raising Citizens: Parenting Education Classes and Somali Mothers’ Experiences of Childrearing in Canada

Directory of Open Access Journals (Sweden)

Melissa Fellin

2015-09-01

Full Text Available Mothers are viewed as the people who are raising future citizens of Canada; therefore, their parenting practices are being targeted for intervention by civic organizations funded by the state. In this article, I argue that modernity narratives and neoliberalism approaches to mothering inform parenting education classes for Somali refugee women to Canada. Thus, Somali women are often seen as victims. Stereotyped identities conceal their social and historical agency. This research draws on 15 individual interviews with Somali mothers and participant- observation in two parenting education classes in Canada.

Gråstén, Arto; Jaakkola, Timo; Liukkonen, Jarmo; Watt, Anthony; Yli-Piipari, Sami

2012-01-01

The specific aim of this study was to examine whether motivational climate, perceived physical competence, and exercise motivation predict enjoyment in school physical education within the same sample of adolescents across three years of secondary school. A sample of 639 students (girls = 296, boys = 343) aged between 13- to 15-years at the commencement of the study completed the Intrinsic Motivation Climate in Physical Education Questionnaire, Physical Self-Perception Profile, Physical Education Motivation Scale, and Physical Education Enjoyment Scale. Results derived from path analyses indicated that task-involving motivational climate predicted enjoyment in physical education via perceived physical competence and intrinsic motivation in both girls and boys. In particular, these results supported previous findings of Vallerand et. al (1997) with the self-determination theory and the achievement goal theory. Ego-involving climate was not a significant predictor either in girls or boys. The current results provide continuing support for the investigation of Vallerand's model in the physical education setting, and highlight that motivational climate is an area that requires further evaluation as a contributing factor in the improvement of physical education teaching. A better understanding of the role of motivational climate may assist efforts to promote children's and adolescents' perceived physical competence, intrinsic motivation, and enjoyment in the school physical education setting. Key pointsThe findings of the current study support existing suggestions of Vallerand's (1997) model in which social factors mediated by a psychological mediator, and exercise motivation are related to positive consequences in the PE context.Task-involving motivational climate predicted PE enjoyment via perceived physical competence and intrinsic motivation with both girls and boys. Task-involving motivational climate in PE lessons at Grade 7 had a strong association with PE

Vegetable oil (VO) is the most potential alternative to replace mineral oil for lubricant due to better lubricating properties and great physicochemical properties. Chemical modification has to be done to overcome low temperature performance and low oxidation instability due to the presence of β-hydrogen atoms of glycerol molecule. The optimization of esterification of oleic acid and polyhydric alcohol with sulfuric acid catalyst was carried out to find the optimum conditions with the highest yield. Reeaction variables such as; molar ratio, temperature, duration and catalyst concentration. Two types of polyhydric alcohol have been used; TMP and PE. The optimum results showed oleic acid successfully converted 91.2% ester TMP and 92.7% ester PE at duration: 5 hours (Ester TMP), 6 hours (Ester PE); temperature: 150°C (ester TMP), 180°C (Ester PE); catalyst concentration: 1.5% (w/w); and mol ratio: 3.9:1 (ester TMP), 4.9:1 (ester PE). From the data obtained, mole ratio showed most influenced factors to the increasing yields of ester conversions.. The TMP/PE ester was confirmed using gas chromatography (GC-FID), Fourier Transform Infrared Spectroscopy (FTIR) and Nuclear Magnetic Resonance (NMR)

Graphical abstract: The three-pulse photon echo (3P-PE) spectra of finite molecular systems using direct calculation from electronic Hamiltonians allows peak classification from 3P-PE spectra dynamics. Display Omitted Highlights: → RWA approach to electronic photon echo. → A straightforward calculation of 2D electronic spectrograms in finite molecular systems. → Importance of population time dynamics in relation to inter-site coherent coupling. - Abstract: The three-pulse photon echo (3P-PE) spectra of finite molecular systems and simplified line broadening models is presented. The Fourier picture of a heterodyne detected three-pulse rephasing PE signal in the δ-pulse limit of the external field is derived in analytic form. The method includes contributions of one and two-excitonic states and allows direct calculation of Fourier PE spectrogram from corresponding Hamiltonian. As an illustration, the proposed treatment is applied to simple systems, e.g. 2-site two-level system (TLS) and n-site TLS model of photosynthetic unit. The importance of relation between Fourier picture of 3P-PE dynamics (corresponding to nonzero population time, T) and coherent inter-state coupling is emphasized.

Race, Class, and Cultural Reproduction: Critical Theories in Urban Education

Directory of Open Access Journals (Sweden)

Elaine M. Walker

2003-11-01

Full Text Available In spite of decades of reform attempts urban education remains an intractable policy issue for educators. National and state level data continue to show disparities in educational achievement and attainment between students from affluent and poor urban communities. If past policies have not proven to be effective in substantially improving urban educational systems the question is why? In this paper the argument is raised that urban educational policies lack sound epistemological grounding. Policies are divorced from an understanding of the “urban problematic”. Functionalist in orientation these policies have for the most part sought to “fix” urban schools by focusing on micro-ecological issues. In this paper three theoretical perspectives are explored for their potential contribution to inform research and policy on urban educational issues. The three perspectives are: 1 class theories 2 critical race theory and 3 cultural reproduction theories.

Recombination in pe/ppe genes contributes to genetic variation in Mycobacterium tuberculosis lineages

KAUST Repository

Phelan, Jody E.

2016-02-29

Background Approximately 10 % of the Mycobacterium tuberculosis genome is made up of two families of genes that are poorly characterized due to their high GC content and highly repetitive nature. The PE and PPE families are typified by their highly conserved N-terminal domains that incorporate proline-glutamate (PE) and proline-proline-glutamate (PPE) signature motifs. They are hypothesised to be important virulence factors involved with host-pathogen interactions, but their high genetic variability and complexity of analysis means they are typically disregarded in genome studies. Results To elucidate the structure of these genes, 518 genomes from a diverse international collection of clinical isolates were de novo assembled. A further 21 reference M. tuberculosis complex genomes and long read sequence data were used to validate the approach. SNP analysis revealed that variation in the majority of the 168 pe/ppe genes studied was consistent with lineage. Several recombination hotspots were identified, notably pe_pgrs3 and pe_pgrs17. Evidence of positive selection was revealed in 65 pe/ppe genes, including epitopes potentially binding to major histocompatibility complex molecules. Conclusions This, the first comprehensive study of the pe and ppe genes, provides important insight into M. tuberculosis diversity and has significant implications for vaccine development.

The aim of this study was to present a comprehensive review of the literatures describing barriers and facilitators of patient education (PE) perceived by Iranian nurses in order to explain clinical applicability of patient education. Review of the literature was undertaken using the international databases including PubMed/Medline, Scopus, ScienceDirect, as well as Google Scholar. Also, Persian electronic databases such as Magiran, SID and IranMedex were searched. Electronic databases were searched up from conception to September 2014 using search terms: "patient education", " patients education", "patient teaching", "patient training", "nurse", " nurses", " nursing", " and "Iran". Only studies were included that were related to barriers and facilitators of PE among Iranian nurses. Twenty-seven studies were included. The main influential barriers were categorized into three major areas: 1) Nurse-related factors: nursing shortage 2) Administration-related factors: unsupportive organizational culture, and 3) Patient-related factors: low compliance. The most perceived facilitators were recognized as "increasing, selecting and training special nurses for providing PE" and "providing PE courses for nurses and appropriate facilities for PE". Iranian nurses encounter barriers in PE, and the most frequently encountered barriers were related to administration factors. These findings have implications for administrators and managers in health settings. In order to promote PE among nurses, administrators should create a supportive environment and use effective strategies to smooth the progress of PE by nurses in their practice in order to ensure optimal outcomes for patients.

A review of factors affecting the attractiveness of Angola to private equity (PE investments

Directory of Open Access Journals (Sweden)

Estefania Jover

2014-11-01

Full Text Available Angola’s attractiveness to PE investors and the potential to increase PE investments in the country are explored. Primary data were collected using a survey of 18 PE funds that invest or have considered investing in Angola, followed by 10 expert interviews to gain deeper insight into the country’s institutional and economic environment, and its potential for PE investments. It is found that most PE funds are attracted to Angola by its rapid economic growth and high potential returns. The country is also vastly undersupplied, and many key economic sectors are fast developing, presenting exciting opportunities for investors. Nevertheless, PE in Angola remains limited, mainly owing to the difficulty of doing business in Angola, and owing particularly to the unfavourable regulatory environment. There is no regulation or process when it comes to the registration of PE funds in Angola, and any new regulation that applies to foreign investments is marred by unnecessary red tape, making it difficult for the investment to enter the market. Only two funds are authorised to operate in Angola: Fundo de Investimento Privado de Angola (FIPA, and BESA Activ. Streamlining regulation is critical to increasing PE flows to Angola in order to advance the country’s economic and social objectives.

In the framework of Biology Didactics classes the biology students of the Faculty of Natural Sciences at the University of Szczecin participate actively in the works on didactic nature trail in the Arkoñski Woods prepared by Dr. Ewa Fleszar. During the work on didactic natural path the students make themselves acquainted with: field class objectives; field class tasks; field class programmes, e.g. concerning phenology; flora and fauna species. Writing synopsis of field classes for selected lesson units at different teaching levels they acquire sound knowledge based on the ecological contents. Contacts with nature as well as gaining the experience during field classes allow them to obtain competences for working in the field and to understand the objectives of carrying out such classes. Field classes have an effect on developing interests of participants in the subject, and affect the improvement of teaching performance. Visit to the field forms ecological awareness, which leads to obtaining an ecological culture.

This study aims to evaluate the effectiveness of two school-based physical education (PE) programmes (exercise-based and games-based) compared with traditional PE, on health- and skill-related physical fitness components in children in Tirana, Albania. Participants were 378 first-grade (6.8 years) and 389 fourth-grade (9.8 years) children attending four randomly selected schools in Tirana. Twenty-four school classes within these schools were randomly selected (stratified by school and school grade) to participate as exercise group (EG), games group (GG) and control group (CG). Both EG and GG intervention programmes were taught by professional PE teachers using station/circuit teaching framework while CG referred to traditional PE school lessons by a general teacher. All programmes ran in parallel and lasted 5 months, having the same frequency (twice weekly) and duration (45 min). Heart rate (HR) monitoring showed that intensity during PE lessons was significantly higher in the intervention groups compared with control (P games programmes significantly improved several health- and skill-related fitness indicators compared with traditional PE lessons (e.g. gross motor skill summary score: 9.4 (95% CI 7.9; 10.9) for exercise vs. control and 6.5 (95% CI 5.1; 8.1) for games vs. control, cardiorespiratory fitness: 2.0 ml O2 · min(-1) · kg(-1) (95% CI 1.5; 2.4) for exercise vs. control and 1.4 ml O2 · min(-1) · kg(-1) (95% CI 1.0; 1.8) for games vs. control). Furthermore, compared to games-based PE, exercise-based PE showed more positive changes in some gross motor coordination skills outcomes, coordination skills outcomes and cardiorespiratory fitness. The results from this study show that exercise- and games-based PE represents a useful strategy for improving health- and skill-related physical fitness in Albanian elementary school children. In addition, the study shows that exercise-based PE was more effective than games-based PE in improving gross motor function

Public Education: A Route into Lebanon’s Middle Class in the 1960s and Early 1970s

Directory of Open Access Journals (Sweden)

Youssef Zbib

2014-05-01

Full Text Available In Lebanon during the 1960s, public education became more accessible to members of the lower classes and different sectarian denominations, after a time when education had been, to a large extent, a privilege of upper- and middle-class Christians. This paper examines the socioeconomic conditions of public school teachers as a result of this process. Using Bourdieusian analysis, I argue that these teachers used cultural capital acquired through free education to become part of a rising professional middle class. To a large extent, these teachers’ definition of their own social positions and roles was a result of their individual histories and internalized values.

To investigate whether sedentary behavior during school-time is associated with gender, age, mother's education, having physical education classes, weight status, and academic performance. Cross-sectional study. A sample of 571 children (7-12 years old) from five elementary schools in Florianopolis, South Brazil had their height and weight measured, and wore accelerometers during class time. Teachers completed a form to evaluate children's reading and writing skills. Parents provided sociodemographic and educational information. Data was analyzed using multilevel linear regression analyses. Children spent an average of 132min in sedentary behavior during school-time (64% of total school-time). Girls (137.5min), obese children (138.1min), older children (144.2min), and those who did not have physical education classes (140.2min) spent more time engaged in sedentary activities than their peers. Academic performance and mother's education were not associated with sedentary behaviors. Children spent most of their school-time in sedentary activities, with girls, older students, and obese students being even more sedentary than their peers. Physical education classes were a protective factor against excessive sedentary behavior in school. Interventions for reducing sedentary behavior during school-time could employ additional strategies to benefit the at risk groups. In addition, encouraging student's participation in physical education classes could minimize the time spent in sedentary behavior during school hours. Copyright © 2016 Sports Medicine Australia.

Active Bilayer PE/PCL Films for Food Packaging Modified with Zinc Oxide and Casein

Directory of Open Access Journals (Sweden)

Ana Rešček

2015-12-01

Full Text Available This paper studies the properties of active polymer food packaging bilayer polyethylene/polycaprolactone (PE/PCL films. Such packaging material consists of primary PE layer coated with thin film of PCL coating modified with active component (zinc oxide or zinc oxide/casein complex with intention to extend the shelf life of food and to maintain the quality and health safety. The influence of additives as active components on barrier, mechanical, thermal and antimicrobial properties of such materials was studied. The results show that, in comparison to the neat PE and PE/PCL films, some of PE/PCL bilayer films with additives exhibit improved barrier properties i.e. decreased water vapour permeability. Higher thermal stability of modified PE/PCL material is obtained due to a modified mechanism of thermal degradation. The samples with the additive nanoparticles homogeneously dispersed in the polymer matrix showed good mechanical properties. Addition of higher ZnO content contributes to the enhanced antibacterial activity of a material.

The purpose of this study was to identify student clusters with homogenous profiles in perceptions of task- and ego-involving, autonomy, and social relatedness supporting motivational climate in school physical education. Additionally, we investigated whether different motivational climate groups differed in their enjoyment in PE. Participants of the study were 2 594 girls and 1 803 boys, aged 14-15 years. Students responded to questionnaires assessing their perception of motivational climate and enjoyment in physical education. Latent profile analyses produced a five-cluster solution labeled 1) 'low autonomy, relatedness, task, and moderate ego climate' group', 2) 'low autonomy, relatedness, and high task and ego climate, 3) 'moderate autonomy, relatedness, task and ego climate' group 4) 'high autonomy, relatedness, task, and moderate ego climate' group, and 5) 'high relatedness and task but moderate autonomy and ego climate' group. Analyses of variance showed that students in clusters 4 and 5 perceived the highest level of enjoyment whereas students in cluster 1 experienced the lowest level of enjoyment. The results showed that the students' perceptions of various motivational climates created differential levels of enjoyment in PE classes.

2014-01-01

In Lebanon during the 1960s, public education became more accessible to members of the lower classes and different sectarian denominations, after a time when education had been, to a large extent, a privilege of upper- and middle-class Christians. This paper examines the socioeconomic conditions of public school teachers as a result of this process. Using Bourdieusian analysis, I argue that these teachers used cultural capital acquired through free education to become part of a rising profess...

Various organizations have suggested that physical education (PE) should play a central role in increasing adolescents' physical activity (PA) levels. The purpose of this study was to examine relationships between students' self-determined motivation and their PA behavior during a structured PE lesson led by their teacher and a free-choice period in which they were not required to be active. 528 Hong Kong students (mean age=15.78 years) participated in this study in April and May 2007. Situational Motivation Scale scores were used to form high and low self-determined motivation groups. Students wore a pedometer during a 20-minute structured basketball lesson and a 20-minute free choice period, during which they did not receive instruction. ANOVA revealed that self-determined motivation and PE class environments which provided students opportunities to make choices were related to greater PA. Furthermore, the difference in PA between the high and low self-determined groups was greater in the free-choice condition than the structured lesson, suggesting that self-determined motivation is especially important when students are not supervised. Findings indicated that promoting self-determined motivation may be an effective means of ensuring that PE programs are able to increase PA levels, foster self-initiated PA behaviors, and enhance adolescents' health.

Everyday Physical Education: Functional and Dysfunctional Consequences in Hungarian Public Education

Vamos Ảgnes

2015-09-01

Full Text Available In Participation in physical education is considered to be a fundamental right of pupils all over the world. In Hungary, where the rich elite sports traditions of the country are paralleled by the population’s moderate physical activity, the challenge posed by non-communicable diseases and growing obesity figures among youth was addressed by the introduction of daily P.E. in public education starting in the 2012/13 academic year. The objective of the present paper is to discuss, based on empirical research, the intended and unintended consequences of this measure in an educational and social context using the qualitative analysis of the views of key stakeholders and the quantitative analysis of statistical data on the infrastructural and personal conditions of P.E. The results indicate that neither before nor after the enforcement of the Act on Public Education were the infrastructural and personal conditions of daily P.E. created and, in addition to the intended consequences, a number of unintended consequences have also been encountered by various stakeholders. The study can also be regarded as an attempt to reveal these dysfunctions in order to contribute to positive changes in the area.

Long-lived quantum coherences have been shown experimentally in the Fenna–Matthews–Olson (FMO) complex of green sulfur bacteria as well as in the phycoerythrin 545 (PE545) photosynthetic antenna system of marine algae. A combination of classical molecular dynamics simulations, quantum chemistry and quantum dynamical calculations is employed to determine the excitation transfer dynamics in PE545. One key property of the light-harvesting system concerning the excitation transfer and dephasing phenomena is the spectral density. This quantity is determined from time series of the vertical excitation energies of the aggregate. In the present study we focus on the quantum dynamical simulations using the earlier QM/MM calculations as input. Employing an ensemble-averaged classical path-based wave packet dynamics, the excitation transfer dynamics between the different bilins in the PE545 complex is determined and analyzed. Furthermore, the nature of the environmental fluctuations determining the transfer dynamics is discussed. - Highlights: • Modeling of excitation energy transfer in the light-harvesting system PE545. • Combination of molecular dynamics simulations, quantum chemistry and quantum dynamics. • Spectral densities for bilins in the PE545 complex.

Moreno, Megan; Breuner, Cora C; Lozano, Paula

2008-10-01

Recent data show US adolescents are engaging in sexual activity at earlier ages; however, little is known about young teens' sexual attitudes and behaviors. Examining teens' questions in sex education classes may provide insight into these attitudes and behaviors. Quasi cohort study Parochial middle school sex education classes 5(th) through 8(th) graders Students' anonymous written questions submitted at the outset of sex education classes between 2003 and 2005. Questions were classified into topic categories. Three additional variables were then coded for each question. Ethics/guidance questions included requests for advice or value judgments. Prohibited questions included the topics homosexuality, abortion, masturbation, and contraception. "Red flag" questions were those that suggested consideration of or engagement in sexual behavior. Among 473 questions submitted by 410 students, the most popular topics for 5(th)/6(th) graders were pregnancy and puberty, and for 7(th)/8(th) graders puberty and menstruation. 41 questions (8.6%) were prohibited. 29 questions (6.2%) asked about ethics/guidance. 18 questions (3.81%) were coded as red flag questions. A chi-square analysis showed that 5(th)/6(th) graders asked more questions in the ethics/guidance (8.3% versus 3.64%) and red flag question categories (5.53% versus 1.82%) (P < 0.05) than 7(th)/8(th) graders. Although provocative questions represent a minority of these middle students' queries, these requests suggest the urgency of providing appropriate guidance to young teens, given the risks of early sexual activity. The role of school education programs, physicians and parents in addressing questions of this sort should be considered.

Farrell, K.; Packan, N.H.

1981-01-01

The Nimonic PE16 alloy in solution-treated-and-aged condition was bombarded simultaneously with nickel ions and α and deuteron beams at 625 0 C to doses of 80 to 313 dpa at He/dpa = 10 and D/dpa = 25. Microstructural changes consisted of the introduction of dislocations and of cavities, and the redistribuion of γ' precipitates to these defects. Cavitational swelling remained below 1%. Cavities were represented by several distinct size classes, the smaller ones believed to be gas bubbles, and some larger ones associated with preferred growth of precipitate. Formation of bubbles at grain boundaries, and large cavities at incoherent twins intensified the possibility of mechanical separation of interfaces under high-gas irradiation conditions

TeV-PeV neutrinos from low-power gamma-ray burst jets inside stars.

Science.gov (United States)

Murase, Kohta; Ioka, Kunihito

2013-09-20

We study high-energy neutrino production in collimated jets inside progenitors of gamma-ray bursts (GRBs) and supernovae, considering both collimation and internal shocks. We obtain simple, useful constraints, using the often overlooked point that shock acceleration of particles is ineffective at radiation-mediated shocks. Classical GRBs may be too powerful to produce high-energy neutrinos inside stars, which is consistent with IceCube nondetections. We find that ultralong GRBs avoid such constraints and detecting the TeV signal will support giant progenitors. Predictions for low-power GRB classes including low-luminosity GRBs can be consistent with the astrophysical neutrino background IceCube may detect, with a spectral steepening around PeV. The models can be tested with future GRB monitors.

Ring ductility of irradiated Inconel 706 and Nimonic PE16

International Nuclear Information System (INIS)

Huang, F.H.; Fish, R.L.

1984-01-01

The tensile ductility of fast neutron-irradiated, precipitation-hardened alloys Inconel 706 and Nimonic PE16 has been observed to be very low for certain test conditions. Explanations for the low ductility behavior have been sought by examination of broken tensile specimens with microscopy and other similar techniques. A ring compression test provides a method of evaluating the ductility of irradiated cladding specimens. Unlike the conventional uniaxial tensile testing in which the tensile specimen is deformed uniformly, the ring specimen is subjected to localized bending where the crack is initiated. The ductility can be estimated through an analysis of the bending of a ring in terms of strain hardening. Ring sections from irradiated, solution-treated Inconel 706 and Nimonic PE16 were compressed in the diametral direction to provide load-deflection records over a wide range of irradiation and test temperatures. Results showed that ductility in both alloys decreased with increasing test temperatures. The poorest ductility was exhibited at different irradiation temperatures in the two alloys - near 550 0 C for PE16 and 460 to 520 0 C for Inconel 706. The ring ductility data indicate that the grain boundary strength is a major factor in controlling the ductility of the PE16 alloy

Pulsar Wind Nebulae inside Supernova Remnants as Cosmic-Ray PeVatrons

Science.gov (United States)

Ohira, Yutaka; Kisaka, Shota; Yamazaki, Ryo

2018-05-01

We propose that cosmic-ray PeVatrons are pulsar wind nebulae (PWNe) inside supernova remnants (SNRs). The PWN initially expands into the freely expanding stellar ejecta. Then, the PWN catches up with the shocked region of the SNR, where particles can be slightly accelerated by the back and forth motion between the PWN and the SNR, and some particles diffuse into the PWN. Afterwards the PWN is compressed by the SNR, where the particles in the PWN are accelerated by the adiabatic compression. Using a Monte Carlo simulation, we show that particles accelerated by the SNR to 0.1 PeV can be reaccelerated to 1 PeV until the end of the PWN compression.

Despite the nation's rising epidemic of childhood obesity and diabetes, schools struggle to promote physical activities that help reduce risks for cardiovascular disease. Emerging data suggest that adopting novel activities into physical education (PE) curriculum may serve as an effective strategy for increasing physical activity in children. The purpose of this investigation was to characterize activity in the water and heart rates (HRs) of high school students participating in surf PE courses. Twenty-four male (n = 20) and female (n = 4) high school students (mean age = 16.7 ± 1.0 years) who were enrolled in surf PE courses at 2 high schools participated in this investigation. Daily measurements of surfing durations, average HR, and maximum HR were made on the students with HR monitors (PolarFT1) over an 8-week period. In addition, HR and activity in the water was evaluated during a single session in a subset of students (n = 11) using a HR monitor (PolarRCX5) and a video camera (Canon HD). Activity and HR were synchronized and evaluated in 5-second intervals during data analyses. The average duration that PE students participated in surfing during class was 61.7 ± 1.0 minutes. Stationary, paddling, wave riding, and miscellaneous activities comprised 42.7 ± 9.5, 36.7 ± 7.9, 2.9 ± 1.4, and 17.8 ± 11.4 percent of the surf session, respectively. The average and maximum HRs during these activities were 131.1 ± 0.9 and 177.2 ± 1.0 b·min, respectively. These data suggest that high school students participating in surf PE attained HRs and durations that are consistent with recommendations with cardiovascular fitness and health. In the future, PE programs should consider incorporating other action sports into their curriculum to enhance cardiovascular health.

[Education in our time: competency or aptitude? The case for medicine. Part II].

Science.gov (United States)

Viniegra-Velázquez, Leonardo

Part II is focused on participatory education (PE), a distinctive way to understand and practice education in contrast to passive education. The core of PE is to develop everyone's own cognitive potentialities frequently mutilated, neglected or ignored. Epistemological and experiential basis of PE are defined: the concept of incisive and creative criticism, the idea of knowledge as each person's own construct and life experience as the main focus of reflection and cognition. The PE aims towards individuals with unprecedented cognitive and creative faculties, capable of approaching a more inclusive and hospitable world. The last part criticizes the fact that medical education has remained among the passive education paradigm. The key role of cognitive aptitudes, both methodological and practical (clinical aptitude), in the progress of medical education and practice is emphasized.

Full Text Available Contextul amplelor schimbări tehnologice determină specificul societăţii axate pe cunoaştere. Politicile cunoaşterii, în acest context, se referă la cercetare, inovaţie, educaţie şi la formarea profesională; politicile educaţionale se referă la trecerea progresivă de la behaviorism spre pragmatism, şi anume: de la acţiune în baza analogiilor, fără implicarea con-ştiinţei (teoria behavioristă la acţiune de cercetare care presupune rezolvarea problemelor din viaţă. Educaţia elevilor, în acest context, presupune nu doar achiziţii teoretice, dar şi formarea unui spirit de investigaţie, necesar pentru partici-parea activă la locul său în comunitate. Din această perspectivă, curriculumul şcolar promovează abordarea unui demers educaţional axat pe competenţe, prin prisma corelaţiei: iniţiativa profesorului – acţiunea elevului („learning by doing”. INVESTIGATION SKILL, KEY ELEMENT OF A SOCIETY CENTERED ON LEARNINGThe context of ample technological advances determines the specifics of a society centered on learning. The learning politics, in this context are referred to research, innovation, education and professional training; the educational politics refer to the progressive transition from behaviorism towards pragmatism, especially from actions based on analogies, without the implication of conscience (the behavioral theory in research, which implies the solving of life’s problems. The education of students, in this context, implies not just theoretical acquirement, but also the forming of a spirit of investigating, needed for an active participation in its place or inside the community. From this perspective, the school curriculum promotes the approach of an educational step based on skills, linking the teacher’s initiative with the student’s action (learning by doing.

Full Text Available Inclusion is a social process in school aims to change attitudes and to build a position to cover everyone without distinction. Thus, the objective was to analyze the representations of deaf students on their inclusion in physical education classes. It is qualitative, descriptive and analytical, attended eight deaf students from 2 public schools in a city in the countryside of Bahia. For data production, it was used a semi -structured interview, through the aid of an interpreter of Brazilian Sign Language (Libras, at the same time, it was translated by the interpreter and transcribed by the researchers. Data analysis used the technique of categorical content analysis. The inclusion of deaf people in physical education classes still failed to materialize and in fact, even having found some teachers with pedagogical actions that proved to be inclusive, yet they still leave many gaps, regarding satisfactory learning of students because they simply just integrate deaf students in the classroom. It is necessary that the school and the teacher ensure that the curriculum is accessible to them, so that they can contribute to the construction of citizenship, motor development, cognitive and social-emotional student.

SCoPE: an efficient method of Cosmological Parameter Estimation

International Nuclear Information System (INIS)

Das, Santanu; Souradeep, Tarun

2014-01-01

Markov Chain Monte Carlo (MCMC) sampler is widely used for cosmological parameter estimation from CMB and other data. However, due to the intrinsic serial nature of the MCMC sampler, convergence is often very slow. Here we present a fast and independently written Monte Carlo method for cosmological parameter estimation named as Slick Cosmological Parameter Estimator (SCoPE), that employs delayed rejection to increase the acceptance rate of a chain, and pre-fetching that helps an individual chain to run on parallel CPUs. An inter-chain covariance update is also incorporated to prevent clustering of the chains allowing faster and better mixing of the chains. We use an adaptive method for covariance calculation to calculate and update the covariance automatically as the chains progress. Our analysis shows that the acceptance probability of each step in SCoPE is more than 95% and the convergence of the chains are faster. Using SCoPE, we carry out some cosmological parameter estimations with different cosmological models using WMAP-9 and Planck results. One of the current research interests in cosmology is quantifying the nature of dark energy. We analyze the cosmological parameters from two illustrative commonly used parameterisations of dark energy models. We also asses primordial helium fraction in the universe can be constrained by the present CMB data from WMAP-9 and Planck. The results from our MCMC analysis on the one hand helps us to understand the workability of the SCoPE better, on the other hand it provides a completely independent estimation of cosmological parameters from WMAP-9 and Planck data

An attempt to develop biodegradable polyethylene film grafting of mixture of hydrophilic monomers methacrylic acid (MAAc) and acrylamide (AAm) onto PE film has been carried out by preirradiation method using benzoyl peroxide as the radical initiator. Since ether linkages are susceptible to easy cleavage during degradation process, PE film was irradiated before the grafting reactions by {gamma}-rays to introduce peroxidic linkages (PE-OO-PE) that offer sites for grafting. The effect of irradiation dose, monomer concentration, initiator concentration, temperature, time and amount of water on the grafting percent was determined. Maximum percentage of grafting of binary mixture (MAAc+AAm), (1792%) was obtained at a total concentration of binary monomer mixture=204.6x10{sup -2} mol/L ([MAAc]=176.5x10{sup -2} mol/L, [AAm]=28.1x10{sup -2} mol/L), [BPO]=8.3x10{sup -2} mol/L at 100 deg. C in 70 min. The grafted PE film was characterized by the Fourier Transform Infrared Spectroscopy (FTIR), Thermogravimetric Analysis (TGA) and Scanning Electron Microscopic (SEM) methods. Some selective properties of grafted films such as swelling studies, ion uptake and biodegradation studies have been investigated. The grafted films show good swelling in water, ion uptake studies shows promising results for desalination of brackish water and the soil burial test shows that PE film grafted with binary monomer mixture degrades up to 47% within 50 days. - Highlights: > Binary mixture of methacrylic acid (MAAc) and acrylamide (AAm) onto PE film by preirradiation method was carried out. > Graft copolymers of MAAc+AAm and PE film were characterized by FTIR, TGA and SEM studies and was found to be thermally stable. > Grafting of MAAc+AAm improved swelling behavior giving maximum swelling (485.71%) in water as against PE with 0% swelling. > The grafted PE-g-poly (MAAc-co-AAm) behaves as an excellent material for ion separation. > Biodegradation studies by soil burial test showed 47.19% of

Class and ideological orientations revisited: an exploration of class-based mechanisms.

Bengtsson, Mattias; Berglund, Tomas; Oskarson, Maria

2013-12-01

Studies of the relationship between class position and political outlooks still only have a limited understanding of the class-related mechanisms that matter for ideological orientations. This article presents a comprehensive analysis of the mechanisms that link class position and left/right and authoritarian/libertarian orientations. Besides main factors such as income, career prospects, job security, education, class origin and class identification, the significance of work-related factors such as work autonomy, working in a team, a physically demanding job and a mentally demanding job is studied. The findings are based on a survey specifically designed for this purpose and collected in Sweden in 2008/2009. A great deal of the association between class position and left/right orientations is explained by socio-economic conditions; different classes sympathize with policies that will benefit them economically. Another important factor is class identification. Work-related factors also have relevance, but the effect of class position on left/right orientations works mainly through the remuneration system. Class position is also related to authoritarian/libertarian orientations. However, this relationship is less explained by socio-economic position per se, but is rather an effect of the educational system and its allocation of the workforce into different class positions. It also turns out that work-related factors do not explain the class effects; however, a physically demanding job shows a unique effect. Overall, our findings suggest that besides factors such as class position, income, education and class identification, we need to consider work-related aspects to derive a more complete understanding of the distribution of ideological orientations in Western societies. © London School of Economics and Political Science 2013.

Multicultural scholarship in sport and exercise psychology should help us understand and apply cultural competencies for all to be physically active. In the present study, two Asian countries, Japan and Singapore, were chosen. The participation rate for physical activities among adolescent girls tends to be lower than that of boys in both countries. Thus, the purpose of the project was to gain knowledge and understanding about sociocultural factors that may explain adolescent girls' perceptions and behaviors toward sport, physical activity, and physical education (PE). A qualitative approach using semi-structured interviews with focus groups was used to understand meanings of physical activity among Buddhist Japanese, and Hindu Indians and Christian Chinese from Singapore. Each focus group consisted of four or five girls and female researchers. Based on the analysis, we created four themes which were "cultural identities," "Asian girls and sport/physical activities," "PE experiences," "motivation for future involvement." The Buddhist Japanese, Hindu Indian, and Christian Chinese participants each reported unique physical activity experiences, and all the participants were aware of how Asian culture may affect being physically active. Experiences of PE classes were similar but perceptions of their PE attire were different for Christian Chinese and Hindu Indian adolescent girls. Based on the results, the importance of nurturing cultural competencies and ways to encourage girls to be physically active throughout life were discussed.

ETVA VI.PE. S.A. is a member of the Piraeus Bank Group of Companies and its activities include designing, developing, exploiting and managing Industrial Areas throughout Greece. Inside ETVA VI.PE.'s thirty-one Industrial Parks there are currently 2,500 manufacturing companies established, with 40,000 employees and € 2.5 billion of invested funds. In each one of the industrial areas ETVA VI.PE guarantees the companies industrial lots of land (sites) with propitious building codes and complete infrastructure networks of water supply, sewerage, paved roads, power supply, communications, cleansing services, etc. The development of Geographical Information System for ETVA VI.PE.'s Industrial Parks started at the beginning of 1992 and consists of three subsystems: Cadastre, that manages the information for the land acquisition of Industrial Areas; Street Layout - Sites, that manages the sites sold to manufacturing companies; Networks, that manages the infrastructure networks (roads, water supply, sewerage etc). The mapping of each Industrial Park is made incorporating state-of-the-art photogrammetric, cartographic and surveying methods and techniques. Passing through the phases of initial design (hybrid GIS) and system upgrade (integrated Gis solution with spatial database), the system is currently operating on a new upgrade (integrated gIS solution with spatial database) that includes redesigning and merging the system's database schemas, along with the creation of central security policies, and the development of a new web GIS application for advanced data entry, highly customisable and standard reports, and dynamic interactive maps. The new GIS bring the company to advanced levels of productivity and introduce the new era for decision making and business management.

Full Text Available BACKGROUND: After the year 1989, political, structural and economic reforms caused significant changes in education in the Czech Republic, also affecting physical education (PE. Within the context of unification and globalization there are similar changes in progress in other countries. OBJECTIVE: The complex situation, fast changes and various pedagogical traditions complicate the creation of a systematic view of the current PE reforms. The objective of this paper is to describe the most important events in the history of PE in the Czech Republic, Germany and the USA and to explain their effect on the PE curriculum changes in the selected countries. The purpose of this historical analysis is to present some fundamental information about the development of PE in selected countries which will make possible further comparisons of the current reforms of physical education. METHODS: Our methodology is based on historical comparison outlining and comparing the history of the PE concepts in selected countries. RESULTS: Our results and findings show the differences in the history of PE in the Czech Republic, Germany and the USA and the crosscultural influence of the countries on the development of PE concepts. Especially the Turners from Germany influenced the beginnings of Czech and American PE in the 19th century. Other gymnastic systems entered the USA later but the philosophy of pragmatism and the influence of the modern Olympic movement brought significant changes into the American PE concept at the beginning of the 20th century. As a consequence, the gymnastic systems have been replaced with the "sport recreational" concept. In the 20th century the emphasis on physical education changed repeatedly when conflicts between countries occurred. For example the German, Czech and American PE emphasis shifted from games and sport to physical conditioning after WWI and WWII and also after the Korean and Vietnam War in the USA. Further differences in PE

Full Text Available The following study proves the thesis that in present-day Polish conditions children’s education does not depend on their intellectual capacity, but it rather depends on the financial background, the social and cultural capital and parent’s social class. In addition, family status and family members contribute to a child’s position in a specific social space. At the beginning I would like to indicate Pierre Bourdieu’s theory as the main basis upon which this study is based, afterwards I present selected conceptions and definitions of the middle class. In the next part I describe the research concerning middle class children’s standard of education. This is the background on which I present the program of self-study and its results. The materials presented show the value which is assigned by parents to their children, their upbringing, and education. In addition, it enables one to analyse the mentality of this specific group of parents and the educational patterns which they use to support their children. The research results and the opinions described in the text lead us to assume that parents from the middle class provide their children with practically unlimited support, which will help them in the future to reconstruct their social status. In general, the main goal of parents from the middle class is to create life chances for their children, so they can succeed in life. The analysis proves that middle class children can count on financial, material, psychological, and public support from their parents. In my paper I elaborate on how much importance middle class parents attach to their children’s education as well as what their expectations and plans related to education are

E. David

2013-01-01

Full Text Available Polyethylene/nanoclay specimens containing from 0 to 5% nanoclays were prepared from a commercially available premixed PE/nanoclay masterbatch containing 50% wt of nanoclay. The masterbatch was diluted to the desired concentration by adding PE along with various amounts of compatibilizer in order to achieve the best possible dispersion of the nanoclay platelets. The dielectric response of the compounded samples was investigated using a combination of time and frequency-domain spectroscopy in order to cover a wide frequency window. Both techniques were in good agreement when the time-domain data was transformed into frequency-domain data. Despite their low concentration, the addition of the dispersed nanoclays led to a significant alteration of the material dielectric response in the form of the appearance of various interfacial relaxation processes and an increase of charge carrier transport within the insulation material. Moreover, an onset of nonlinear charge transport process was observed at moderate fields for specimens containing a relatively low level of nanoclays. The high-field breakdown strength was shown to have been improved by the incorporation of the nanoparticles, particularly when the exfoliation was enhanced by the use of a maleic anhydride grafted polyethylene compatibilizer.

Shock Wave Speed and Transient Response of PE Pipe with Steel-Mesh Reinforcement

Directory of Open Access Journals (Sweden)

Wuyi Wan

2016-01-01

Full Text Available A steel mesh can improve the tensile strength and stability of a polyethylene (PE pipe in a water supply pipeline system. However, it can also cause more severe water hammer hazard due to increasing wave speed. In order to analyze the influence of the steel mesh on the shock wave speed and transient response processes, an improved wave speed formula is proposed by incorporating the equivalent elastic modulus. A field measurement validates the wave speed formula. Moreover, the transient wave propagation and extreme pressures are simulated and compared by the method of characteristics (MOC for reinforced PE pipes with various steel-mesh densities. Results show that a steel mesh can significantly increase the shock wave speed in a PE pipe and thus can cause severe peak pressure and hydraulic surges in a water supply pipeline system. The proposed wave speed formula can more reasonably evaluate the wave speed and improve the transient simulation of steel-mesh-reinforced PE pipes.

Supplementary Material for: Recombination in pe/ppe genes contributes to genetic variation in Mycobacterium tuberculosis lineages

KAUST Repository

Phelan, Jody

2016-01-01

Abstract Background Approximately 10 % of the Mycobacterium tuberculosis genome is made up of two families of genes that are poorly characterized due to their high GC content and highly repetitive nature. The PE and PPE families are typified by their highly conserved N-terminal domains that incorporate proline-glutamate (PE) and proline-proline-glutamate (PPE) signature motifs. They are hypothesised to be important virulence factors involved with host-pathogen interactions, but their high genetic variability and complexity of analysis means they are typically disregarded in genome studies. Results To elucidate the structure of these genes, 518 genomes from a diverse international collection of clinical isolates were de novo assembled. A further 21 reference M. tuberculosis complex genomes and long read sequence data were used to validate the approach. SNP analysis revealed that variation in the majority of the 168 pe/ppe genes studied was consistent with lineage. Several recombination hotspots were identified, notably pe_pgrs3 and pe_pgrs17. Evidence of positive selection was revealed in 65 pe/ppe genes, including epitopes potentially binding to major histocompatibility complex molecules. Conclusions This, the first comprehensive study of the pe and ppe genes, provides important insight into M. tuberculosis diversity and has significant implications for vaccine development.

To examine the combined effects of education level and perceived social class on self-rated health and life satisfaction in South Korea. We used data drawn from the 8 to 15th wave of the Korean Labor and Income Panel Study (KLIPS). Using wave 8 at baseline, data included 11,175 individuals. We performed a longitudinal analysis at baseline estimating the prevalence of self-rated health and life satisfaction among individuals by education level (high, middle, and low education level) and perceived social class (high, middle, and low social class). For self-rated health, odds ratio (OR) of individuals with low education and low perceived social class was 0.604 times lower (95% CI: 0.555-0.656) and the OR of individuals with low education and middle perceived social class was 0.853 time lower (95% CI: 0.790-0.922) when compared to individuals with high education and high perceived social class. For life satisfaction, OR of individuals with low education and low perceived social class was 0.068 times lower (95% CI: 0.063-0.074) and the OR of individuals with middle education and middle perceived social class was 0.235 time lower (95% CI: 0.221-0.251) compared to individuals with high education and high perceived social class. This study shows that the combined effects of education level and perceived social class associated with self-rated health and life satisfaction. Our study suggests increasing education level and perceived social class. Additionally, it will be important to develop multi-dimensional measurement tools including education level and subjective social class.

To examine the influence of state laws and district policies on district-wide elementary school and middle school practices related to physical education (PE) time and the percentage of moderate-to-vigorous physical activity (MVPA) time during PE. Multivariate, cross-sectional analysis of state laws, district wellness and PE policies, and district PE practices for school year 2010-2011 controlling for district-level urbanicity, region, size, race/ethnicity of students, and socioeconomic status and clustered on state. One hundred ninety-five public school districts located in 42 states. District-level PE coordinators for the included districts who responded to an online survey. Minutes and days of PE per week and percent time spent in MVPA during PE time. District PE coordinators reported significantly less PE time than national standards-82.9 and 189.6 minutes at the elementary school and middle school levels, respectively. Physical education was provided an average of 2.5 and 3.7 days per week, respectively; and the percentage of MVPA time in PE was 64.4% and 65.7%, respectively. At the elementary school level, districts in either states with laws governing PE time or in a state and district with a law/policy reported significantly more days of PE (0.63 and 0.67 additional days, respectively), and districts in states with PE time laws reported 18 more minutes of PE per week. At the middle school level, state laws were associated with 0.73 more days of PE per week. Neither state laws nor district policies were positively associated with percent MVPA time in PE. State laws and district policies can influence district-level PE practices-particularly those governing the frequency and duration of PE-although opportunities exist to strengthen PE-related laws, policies, and practices.

Since the platform "Coursera" is created by the professors of Stanford University Andrew Ng and Daphne Koller, more and more universities have joined in it. From the very beginning, online education is not only about education itself, but also connected with social equality. This is especially significant for the economic transformation in China. In this paper the research and practice on informatization of optical education are described. Online to offline (O2O) education activities, such as online learning and offline meeting, online homework and online to offline discussion, online tests and online to offline evaluation, are combined into our teaching model in the course of Applied Optics. These various O2O strategies were implemented respectively in the autumn-winter small class and the spring-summer middle class according to the constructivism and the idea of open education. We have developed optical education resources such as videos of lectures, light transmission or ray trace animations, online tests, etc. We also divide the learning procedure into 4 steps: First, instead of being given a course offline, students will learn the course online; Second, once a week or two weeks, students will have a discussion in their study groups; Third, students will submit their homework and study reports; Fourth, they will do online and offline tests. The online optical education resources have been shared in some universities in China, together with new challenges to teachers and students when facing the revolution in the e-learning future.

Vocational education and the technical middle class in Spain (1924-1931

María Luisa Rico Gómez

Full Text Available In this study, I examine the extent to which technical-professional education during Primo de Rivera´s dictatorship in Spain influenced the creation of a new middle class of technicians by means of the decrees of the Industrial Education Statute of 1924 and the Professional Staff Training Statute of 1928. These initiatives were aimed at the working class and the petty bourgeoisie that were to later become the supporters of the State´s social and corporative system as well as the promoters of the country´s modernization. However, the disconnection between the economic and social reality, on the one hand, and the State´s objectives, on the other hand, led to the failure of these projects that were decisively interrupted by the establishment of the Spanish Second Republic in 1931. In researching this study, I focus on the legislation enacted on this matter and other printed sources including specialized journals of this period, theoretical writings of contemporary authors and abundant archival material on the dynamics of the industrial schools that were created thanks to this new project.

Peer teaching is recognized as a powerful instructional method; however, there is a paucity of studies that have evaluated the outcomes experienced by peer-teachers and their student recipients in the context of trained, non-reciprocal, high school physical education (PE). Accordingly, the effectiveness of a formalized and trained non-reciprocal peer teaching (T-PT) program upon psychosocial, behavioral, pedagogical, and student learning outcomes within high school PE classes was investigated. Students from eight intact classes (106 males, 94 females, Mage = 12.46, SD = 0.59) were randomly assigned to either a T-PT intervention group (taught by a volunteer peer-teacher who was trained in line with a tactical games approach) or untrained group (U-PT; where volunteer peer-teachers received no formal training, but did receive guidance on the game concepts to teach). Data were collected over 10 lessons in a 5-week soccer unit. Mixed-model ANOVAs/MANOVAs revealed that, in comparison to U-PT, the T-PT program significantly enhanced in-game performance actions and academic learning time among student recipients. Those in the T-PT also provided greater levels of feedback and structured learning time, as well as reporting more positive feelings about peer teaching and fewer perceived barriers to accessing learning outcomes. These findings show that non-reciprocal peer-teachers who receive formalized support through training and tactical games approach-based teaching resources can enhance behavioral, pedagogical, and motor performance outcomes in PE.

Full Text Available Cryptochromes are photolyase-like blue/UV-A light receptors that evolved from photolyases. In plants, cryptochromes regulate various aspects of plant growth and development. Despite of their involvement in the control of important plant traits, however, most studies on cryptochromes have focused on lower plants and herbaceous crops, and no data on cryptochrome function are available for forest trees. In this study, we isolated a cryptochrome gene, PeCRY1, from Euphrates poplar (Populus euphratica, and analyzed its structure and function in detail. The deduced PeCRY1 amino acid sequence contained a conserved N-terminal photolyase-homologous region (PHR domain as well as a C-terminal DQXVP-acidic-STAES (DAS domain. Secondary and tertiary structure analysis showed that PeCRY1 shares high similarity with AtCRY1 from Arabidopsis thaliana. PeCRY1 expression was upregulated at the mRNA level by light. Using heterologous expression in Arabidopsis, we showed that PeCRY1 overexpression rescued the cry1 mutant phenotype. In addition, PeCRY1 overexpression inhibited hypocotyl elongation, promoted root growth, and enhanced anthocyanin accumulation in wild-type background seedlings grown under blue light. Furthermore, we examined the interaction between PeCRY1 and AtCOP1 using a bimolecular fluorescence complementation (BiFc assay. Our data provide evidence for the involvement of PeCRY1 in the control of photomorphogenesis in poplar.

The phytoplankton community is controlled not only by local environmental conditions but also by physical processes occurring on different temporal and spatial scales. Hydrodynamic local conditions play an important role in marine ecosystems. Several studies have shown that hydrodynamic conditions can influence the phytoplankton settling velocity, vertical and horizontal distribution and formation of cyanobacterial blooms. Mesocosms are useful structures to simulate marine environment at mesoscale resolution; allowing to closely approximate biotic or abiotic parameters of interest directly in nature. In this work an innovative structure named PE.MA.M (PElagic MArine Mesocosm) is presented and tested. Laboratory experiments have been conducted in order to observe seasonal variations of biomass behaviour in two different hydrodynamic conditions: outside as well as whithin the PE.MA.M. We have evaluated whether it is possible to isolate a natural system from external water mass hydrodynamic exchanges and to assume that phytoplankton cells' transition is limited at the net and sea interface. Preliminary experiments test the isolating capacity of the net, to determine the currents' attenuation rate and to estimate the possible PE.MA.M. offshore behaviour. In the first investigation, we monitored the diffusion of phytoplankton cells. The PE.MA.M. exterior and interior were simulated using a plexiglass tank divided into two half-tanks (Aout-Bin) by a septum consisting of a net like a PE.MA.M. The tank was filled up with 10 L of water and only the half-tank Aout was filled up with 10 ml of phytoplankton culture (Clorella sp.). We monitored the chlorophyll concentrations for 24 hours. The two tanks had similar concentrations after 4 hours (2.70322 mg/m³ Aout and 2.37245 mg/m3 Bin) and this constant relationship was maintened until the end of the test. In the second investigation we used clod cards to measure water motions.We conducted two experiments within tank, the first

Real-world educational experience through project-oriented graduate classes in collaboration with industry

There is a need for a motivated and innovative work force for the U.S. aerospace industry. The education of such engineers and scientists typically revolves around a fundamental knowledge of basic important technologies, such as the mechanics relevant to orbit-design, structures, avionics, and many others. A few years ago, the University of Michigan developed a Masters of Engineering program that provides students with skills that are not taught as part of a typical engineering curriculum. This program is focused on open problem solving, space systems, and space policy, as well as other classes that further their understanding of the connections between technologies and the nontechnical aspects of managing a space mission. The value of such an education is substantially increased through a direct connection to industry. An innovative problem-oriented approach has been developed that enables direct connections between industry and classroom teaching. The class works as a system study group and addresses problems of interest to and defined by a company with a specific application. We discuss such an application, a near-space lidar wind measurement system to enhance weather predictions, as well as the approach taken to link educational rationales.

Full Text Available Optimizing physical activity during physical education is necessary for children to achieve daily physical activity recommendations. The purpose of this study was to examine the relationship among various contextual factors with accelerometer measured physical activity during elementary physical education. Data were collected during 2015–2016 from 281 students (1st–5th grade, 137 males, 144 females from a private school located in a metropolitan area of Utah in the U.S. Students wore accelerometers for 12 consecutive weeks at an accelerometer wear frequency of 3days per week during physical education. A multi-level general linear mixed effects model was employed to examine the relationship among various physical education contextual factors and percent of wear time in moderate-to-vigorous physical activity (%MVPA, accounting for clustering of observations within students and the clustering of students within classrooms. Explored contextual factors included grade level, lesson context, sex, and class size. Main effects and interactions among the factors were explored in the multi-level models. A two-way interaction of lesson context and class size on %MVPA was shown to be statistically significant. The greatest differences were found to be between fitness lessons using small class sizes compared to motor skill lessons using larger class sizes (β=14.8%, 95% C.I. 5.7%–23.9% p<0.001. Lessons that included a focus on fitness activities with class sizes that were <25 students associated with significantly higher %MVPA during elementary physical education.

A quantitative consideration on the absorbed energy consumption in various γ-irradiated polyethylene systems is given. On the base of the increased gel dose values for the PE systems containing antioxidant, relative to the gel doses for the pure polymers, the surplus of the absorbed energy due to the presence of the particular antioxidant is calculated. The increasing of the energy consumption in the stabilized systems depends on both the type and the content of the basic polymer. The surplus in the absorbed energy decreases with the radiation dose increasing, reflecting both the diminishing of the antioxidant concentration in the irradiating PE systems and the crosslinking level. The findings can be of interest in the estimation of the absorbed doses for the specific radiation crosslinking processes. (author)

Full Text Available We examine the components of equity returns on the Polish capital market. To analyse the underlying complexity of returns we took into consideration the model designed by Leibowitz (1999. This model captures three factors: dividend yield, expected growth in earnings and expected change in price-to-earnings (PE ratio. We applied this model to analyse the average discount/premium not only to particular shares but to market averages as well. Firstly, we examined the variation of PE across the companies (as adapted from Penman (1996 to analyse the average rate of return and their striking distance of individual stocks from a ‘normal’ level. Then we checked the transitory earnings in the portfolios of high PE, whereby a fall in current earnings relative to sustainable level of earnings leads to a transitory high PE ratio. We expect that the effect of transience in current year earnings can be significant. Lastly, we analysed the individual companies in order to check what percentage of companies give a “correct” signal about future prospects.

Genetic characterization of plasmid pRJ5 of Staphylococcus aureus compared to plasmid pE194

The pRJ5, a naturally occurring constitutive macrolide, lincosamide and streptogramin B (MLS) resistance plasmid of Staphylococcus aureus, was compared to pE194, a plasmid that confers the inducible phenotype. pRJ5 was stable in all strains of S. aureus tested, even under growth at 43 O C, which distinguished it from pE194 which was shown to be thermo-sensitive for replication. pRJ5, like pE194, was highly unstable in Bacillus subtilis when the cells were grown in nonselective conditions. Multimeric forms of pRJ5 DNA were detected in the few cells of B. subtilis that retained this plasmid. pE194 was transduced by phages φ 11 and φ 443 at frequencies 400 and 20-fold higher, respectively, than pRJ5. Both plasmids were co-transduced with the plasmid pRJ4. pRJ5 was shown to be compatible with pE194. Therefore they belong to distinct Inc groups. Hybridization studies revealed that pRJ5 shares a 1.35 kb region of homology to pE194, which is limited to the erm gene, conferring MLS resistance. (author)

Full Text Available Background: Following the inclusion of children with disabilities in mainstream schools worldwide, legislative changes have recently been introduced in Poland, facilitating educational inclusion of individuals with disabilities. However, practical implementation still requires further action. Attitudes are a major determinant of teachers' behavior. Therefore, based on the Theory of Planned Behavior, the instrument Attitudes Toward Teaching Individuals with Physical Disabilities in Physical Education (ATIPDPE has been developed, and adapted to cultural contexts in several countries (e.g. South Africa, Slovenia, and Greece. Objectives: The aim of this study was to estimate construct validity of the revised ATIPDPE-R instrument to the Polish cultural context (ATIPDPE-R-PL, in order to prepare a reliable scale to measure the attitudes of physical education (PE teachers towards teaching students with physical disabilities in general PE classes.Methods: Participants were 158 in-service PE teachers (100 women and 58 men, range of age from 25 to 60, from primary and secondary schools from Polish schools. Construct validity was obtained throughout the principal component analysis method (PCA. Reliability was estimated through Cronbach's alpha coefficient, where the value of at least .7 was accepted as satisfactory.Results: Based on the analysis, the attitudinal scale of ATIPDPE-R-PL measured three psychological components, which came from the PCA, and explained 66% of the variance similar to the original scale.Conclusions: The three components were positive and negative outcomes for students and negative outcomes for teachers, however items in each component varied from the original scale.

van Vliet, E A; Winnips, J C; Brouwer, N

2015-01-01

In flipped-class pedagogy, students prepare themselves at home before lectures, often by watching short video clips of the course contents. The aim of this study was to investigate the effects of flipped classes on motivation and learning strategies in higher education using a controlled, pre- and posttest approach. The same students were followed in a traditional course and in a course in which flipped classes were substituted for part of the traditional lectures. On the basis of the validated Motivated Strategies for Learning Questionnaire (MSLQ), we found that flipped-class pedagogy enhanced the MSLQ components critical thinking, task value, and peer learning. However, the effects of flipped classes were not long-lasting. We therefore propose repeated use of flipped classes in a curriculum to make effects on metacognition and collaborative-learning strategies sustainable. © 2015 E. A. van Vliet et al.

Coupled Physics Environment (CouPE) library - Design, Implementation, and Release

Energy Technology Data Exchange (ETDEWEB)

Mahadevan, Vijay S. [Argonne National Lab. (ANL), Argonne, IL (United States)

2014-09-30

Over several years, high fidelity, validated mono-­physics solvers with proven scalability on peta-­scale architectures have been developed independently. Based on a unified component-­based architecture, these existing codes can be coupled with a unified mesh-­data backplane and a flexible coupling-­strategy-­based driver suite to produce a viable tool for analysts. In this report, we present details on the design decisions and developments on CouPE, an acronym that stands for Coupled Physics Environment that orchestrates a coupled physics solver through the interfaces exposed by MOAB array-­based unstructured mesh, both of which are part of SIGMA (Scalable Interfaces for Geometry and Mesh-­Based Applications) toolkit. The SIGMA toolkit contains libraries that enable scalable geometry and unstructured mesh creation and handling in a memory and computationally efficient implementation. The CouPE version being prepared for a full open-­source release along with updated documentation will contain several useful examples that will enable users to start developing their applications natively using the native MOAB mesh and couple their models to existing physics applications to analyze and solve real world problems of interest. An integrated multi-­physics simulation capability for the design and analysis of current and future nuclear reactor models is also being investigated as part of the NEAMS RPL, to tightly couple neutron transport, thermal-­hydraulics and structural mechanics physics under the SHARP framework. This report summarizes the efforts that have been invested in CouPE to bring together several existing physics applications namely PROTEUS (neutron transport code), Nek5000 (computational fluid-dynamics code) and Diablo (structural mechanics code). The goal of the SHARP framework is to perform fully resolved coupled physics analysis of a reactor on heterogeneous geometry, in order to reduce the overall numerical uncertainty while leveraging

Lindomar Wessler Boneti

2014-07-01

Full Text Available This article consists of an epistemological reflection on educational policies in order to contribute to the Red Latinoamerica de Estudios Epistemológicos en Política Educativa (ReLePe debate. It is about to rescue the historical journey of the positivist position as classical epistemological framework of the educational policy institutionalization with regard to the implementation of educational action, with special focus to the set of rules, norms and values that conduct school activity. It is argued that these frameworks are constituted from two interconnected movements: historical construction of the epistemological frameworks of science and the Modern State that with the new mode of production, capitalism, gives rise to the second one: bourgeois movement of class distinction based on lifestyle. Thus, from the “Modern Reason”, it was outlined what may be regarded as a “model of civility”, becoming the epistemological framework and goal of achieving the educational policy institutionalization and school activity in contemporaneity.

Jensen, Mette Munk; Agergaard, Sine

2015-01-01

Existing research on inclusion and exclusion processes in physical education (PE) has particularly focused on exclusion from PE as something being done to students and attributed to specific social categories such as (female) gender, (low) physical skills or (minority) ethnic background....... This article aims to develop a social-relational perspective on inclusion and exclusion processes defined as students’ participation or non-participation in PE interpreted as a community of practice. In so doing, the article examines how students’ experiences of participation and non-participation in PE...... or non-participation is important not only in terms of how we talk about students as passive victims or active agents, but also in terms of future intervention aimed at promoting inclusion processes in PE....

Seeing the Wood from the Trees: A Critical Policy Analysis of Intersections between Social Class Inequality and Education in Twenty-first Century Ireland

Directory of Open Access Journals (Sweden)

Kevin CAHILL

2015-12-01

Full Text Available This paper is a critical policy analysis of intersections between social class inequality and education policy in Ireland. The focus is upon contemporary policy and legislation such as The Irish Constitution and equality legislation; social inclusion policies such as the DEIS scheme; literacy and numeracy policy documents; as well as current government policy statements on education. It utilises Stephen Ball’s policy analysis tools of policy as text, policy as discourse and policy effects to examine the social, cultural and political constructs of policy and legislation influencing social class inequality in education in Ireland (Ball, 1993. The focus is upon the refusal to name social class as a significant issue despite the weight of evidence showing the key influence class position and access to economic and cultural resources has on one’s educational opportunities, experiences and outcomes. The approach taken here is discursive in the sense that the documents are the data and the findings are infused with detailed theoretical discussion of contemporary issues around inequality in education in Ireland. The analysis finds that the absence of social class in official policy and legislative discourses is indicative of a growing neoliberalisation of education policy in Ireland where increased foci on international comparisons and a consumer-driven philosophy of educational provision militate against equality for students from lower socio-economic groups.

1983-07-01

Ten adult patients with RPCGN (crescents in greater than 70% of glomeruli), primary in 6 and associated with systemic diseases in 4, were treated with PE, associated with oral steroids (P) and cyclophosphamide (C) in all cases and with intravenous methylprednisolone pulses (MP) in 7 cases. Four out of ten patients were anuric and needed dialysis treatment at the start of treatment. Therapeutic benefit, i.e. reversal of the trend to further deterioration and substantial improvement of GFR, was achieved in 8 out of 10 patients (80%), including 2 of 4 anuric patients, and in 7 of those (8) who had still active cellular crescents (87.5%). Similar therapeutic benefit had been achieved only in 10% of a comparable population of 10 patients with RPCGN treated before 1980 with P and C, without PE or MP pulses. It is difficult to establish whether the better therapeutic results in the more recently treated group were due to PE or to MP pulses of to both the new approaches, even though the clinical improvement obtained in all the 3 patients treated with PE without concomitant MP suggest a specific beneficial role for PE. RPCGN is a catastrophic illness characterized by progressive deterioration of kidney function, resulting in oliguria and uremia, usually within weeks or months. The most consistent histopathologic finding is the presence of extensive glomerular crescents resulting from proliferation of the extracapillary epithelial cell lining of Bowman's capsule. It is apparent that RPCGN is not a homogeneous entity, clinically, histologically or immunohistologically, but rather a clinicopathologic syndrome, the features of which may be seen in a variety of systemic disorders, including SLE, polyarteritis nodosa, Wegener's granulomatosis, Henoch-Schönlein purpura, cryoglobulinemia, and subacute bacterial endocarditis.(ABSTRACT TRUNCATED AT 250 WORDS)

Social class is not often discussed or examined in-depth in couple and family therapy research and literature even though social class shapes familial relationships and is considered an important variable in marital satisfaction. In this qualitative study, we explored the perceptions of eight couples who made lasting commitments across class lines by asking them about the impact of their social class backgrounds on their relationships. Three categories of themes emerged including: (a) differences and similarities in values and attitudes toward education, work, money, and class awareness/classism, (b) relationship issues involving families of origin, friends, and class-based couple conflict, and (c) differences in economic resources, social capital and privileges/opportunities. Implications for assessment and treatment of couples are included. © 2012 American Association for Marriage and Family Therapy.

The national education plan as articulator of the democratization of access to university and empowerment of the working class

Directory of Open Access Journals (Sweden)

Hildegard Susana Jung

2016-09-01

Full Text Available The purpose of this essay, theoretical and documental, is to reflect on the concept(s of empowerment of the working class, in which it invests itself in power, but with an important caveat: this process cannot be individual but collective, through the cooperative dialogue, in which education – especially higher education – is the great protagonist, as articulator of the process. On this track, shows a comparison between the National Education Plan (PNE 2001-2010 and the PNE 2014-2024 regarding the goals aimed to the democratization of the access to university, finding that, in this moment, what can be affirmed in fact is that there were not many advances in Higher Education. Still, the PNE is an important legal instrument for the democratization of access to university, which may serve as an articulator of the empowerment of the working class. Rethinking education means rethinking the entire State, since education policy suffers injunctions of political, economic and social spheres. Enhancing the Brazilian State, means moving towards a broader concept, which will translate a correlation of forces between civil society and politics, which means a greater social participation, increased democratization of access to university and consequently, greater empowerment of the working class through (why not? Higher Education. Therefore, it lies the important role of the academy to prepare educators who disseminate the reflexive practice, which will lead to autonomy and emancipation.

Students' perceptions of the physical education class environment for boys and girls and the perceived motivational climate.

Science.gov (United States)

Papaioannou, A

1998-09-01

Greek students (N = 310) responded to surveys concerning their perceptions of the physical education class environment. Based on factor and reliability analyses, 14 scale scores were computed. Two depicted perceptions of teacher-initiated mastery orientation and teacher-initiated performance orientation. Six scale scores reflected the teacher's negative behavior toward boy's, focus on boys' learning, encouragement toward boys, autonomy given to boys, adjustment of the lesson for boys, and motivation of boys. Six identical scale scores were calculated assessing the physical education class climate for girls. The perception of a teacher who behaves differently toward boys and girls was negatively related to the perception of a teacher who tried to help all students to improve. It is suggested that a mastery orientation increases students' motivation and maintains equality in physical education.

Highlights: • Polyethylene (PE) surface was activated by argon plasma discharge. • Copper nanoparticles were coated on polyethylene via dithiol interlayer. • Prepared samples exhibit excellent structural and magnetic properties. • Studied properties may be utilized in design and fabrication of electronic devices. - Abstract: We report grafting of copper nanoparticles (CuNP) on plasma activated high density polyethylene (HDPE) via dithiol interlayer pointing out to the structural and magnetic properties of those composites. The as-synthesized Cu nanoparticles have been characterized by high-resolution transmission electron microscopy (HRTEM/TEM) and UV–vis spectroscopy. Properties of pristine PE and their plasma treated counterparts were studied by different experimental techniques: X-ray photoelectron spectroscopy (XPS), UV–vis spectroscopy, energy dispersive X-ray spectroscopy (EDS), zeta potential, electron spin resonance (ESR) and SQUID magnetometry. From TEM and HRTEM analyses, it is found that the size of high purity Cu nanoparticles is (12.2 ± 5.2) nm. It was determined that in the CuNPs, the copper atoms are arranged mostly in the (111) and (200) planes. Absorption in UV–vis region by these nanoparticles is ranging from 570 to 670 nm. EDS revealed that after 1 h of grafting are Cu nanoparticles homogeneously distributed over the whole surface and after 24 h of grafting Cu nanoparticles tend to aggregate slightly. The combined investigation of magnetic properties using ESR spectrometry and SQUID magnetometry confirmed the presence of copper nanoparticles anchored on PE substrate and indicated ferromagnetic interactions.

Phycoerythrin (PE) is one of the most important proteins involved in light capturing during photosynthesis in red algae. Its potential biological activities had gained wide concerns. In the present study, tumor cytotoxic and hydroxyl radical assay were preformed to detect the bioactivity of recombinant PE. Recombinant plasmids pGEX-PE and pBGL were transformed into E. coli BL21 to make two recombinant strains BEX (pGEX-PE) and BGL (pBGL). PE expressing in BEX (pGEX-PE) was validated by SDS-PAGE and Western blotting analysis. SDS-PAGE analysis indicated that the PE-GST fusion protein was mostly inclusion bodies. Specific expression of PE was confirmed by Western blotting analysis. The recombinant E. coli BEX (pGEX-PE) cells were collected and sonicated. The supernatants were reserved for the tumor cytotoxic experiments. The result of tumor cytotoxic assay indicated that the supernatants containing PE had the activity of inhibiting the growth of Hela cells and with the increase of protein concentration, the inhibiting rate increased from 37.31% to 63.26%, which showed significant difference from the control. Hydroxyl radical scavenging effect was tested with supernatants of BEX (pGEX-PE) and BGL (pBGL) cell lysates treated with sonication and heating. For the sonication samples, the scavenging rates of the supernatants of BEX (pGEX-PE) and BGL (pBGL) cell lysates were significantly higher than the negative control BL21(pGEX-4T) ( Pprotein content. For the heating samples, except for the 0.2 mg mL-1 BGL (pBGL) products, the scavenging effects of the supernatants of BEX (pGEX-PE) and BGL (pBGL) cell lysates were stronger than that of negative control BL21(pGEX-4T). However, the effect intensity was not positively correlated with the increase of the protein concentration. Though a partially decreased hydroxyl radical scavenging activity was led by heating, the biological activity was still retained and conspicuous. This research showed that phycoerythrin protein

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

2014-08-01

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.

Class categories and the subjective dimension of class: the case of Denmark.

Class relations have been proven to affect various aspects of social life, even in modern individualized societies. However, following claims on individualization and the so-called 'death of class' thesis, studying the subjective dimension of class - that is, the way individuals perceive of class relations and their own position within them - has gone out of style. We argue that even in equalized societies, subjective class perceptions may still influence attitudes and behaviour as they evolve to fit modern class relations. To explore the existence as well as structure and content of perceived social classes, this article investigates how people describe society and social groups in focus group discussions. We find that groups in different positions in terms of education and economy all tend to apply hierarchical class categories to describe Danish society, which is normally seen as one of the most equal societies and political systems in the world. In addition, we find that economic resources serve as a baseline for the hierarchical ordering, often supplemented with notions of education, lifestyle and/or occupational profile. Even though people are somewhat uncomfortable with the notion of class, their descriptions of Danish society and classes are surprisingly similar within and across groups. We conclude that not only do class relations matter; people are also highly aware of the existing classes and able to position themselves and others according to their notion of classes. © London School of Economics and Political Science 2017.

Patient education (PE) is a core treatment of osteoarthritis (OA) with the aim to increase persons' knowledge, self-efficacy, and empowerment. To describe person's various experiences of learning processes in PE for OA. Phenomenography. Semi-structured interviews were performed with the same persons, pre- (11) and post- (9) education. Various experiences on learning processes were found and were described in an outcome space. Achieving knowledge describes self-regulated learning and strongly relates to Control, which describes a high order cognitive learning skill, and minor to Confirm, which describes a cognitive learning skill based on recognition and application. Receiving knowledge describes the expectancy of learning regulated from the educator and strongly relates to Comply, which describes a low-order cognitive learning skill, and minor to Confirm. Different experiences of motivation and learning impact on persons' learning processes which, in turn, influence the persons' capability to accomplish self-efficacy and empowerment. The outcome space may serve as a basis for discussions between healthcare educators involved in PE to better understand what learning implies and to develop PE further.

Massive Open Online Classes (MOOCs) represent a powerful new mode of education and public outreach. While early hype has often given way to disappointment over the typically low completion rates, retaining the interest of free-choice learners is always a challenge, and the worldwide reach and low cost of of these online classes is a democratizing influence in higher education. We have used providers Udemy and Coursera to reach over 60,000 adults with an astronomy course that covers the recent research results across the subject from comets to cosmology. In addition to measures of participation, completion, and performance, we have administered surveys of the learners that measure science literacy, attitudes towards science and technology, and sources of information about science. Beyond the usual core of video lectures and quizzes, we have used peer reviewed writing assignments, observing project, and citizen science to create a richer learning environment. Research on MOOCs is still in its early stages, but we hope to learn what factors contribute most to student engagement and completion in these online settings.

Interest in techniques of surface modification is evinced by the large number of studies in recent decades. In this work the internal surfaces of polymeric membranes of ultra high molecular weight polyethylene (UHMWPE) were modified by impregnation of HDPE/organoclay/PE-g-MA nanocomposite film. The addition of PE-g-MA aims to increase polymer/clay interaction and to control and/or modify surface characteristics of UHMWPE membranes, such as permeability and pore size, so as to make the membranes more efficient and/or appropriate for effluent treatment, more specifically in the treatment of oil contaminated water. The films were analyzed by infrared spectroscopy (FTIR), the modified membranes were characterized by scanning electron microscopy (SEM) and their performance (permeate flux and selectivity) were measured using distilled water and an oil in water dispersion.

A challenge faced by many university-based perfusion education (PE) programs is the need for student clinical rotations at hospital locations that are geographically disparate from the main educational campus. The problem has been addressed through the employment of distance-learning environments. The purpose of this educational study is to evaluate the effectiveness of this teaching model as it is applied to PE. Web-based virtual classroom (VC) environments and educational management system (EMS) software were implemented independently and as adjuncts to live, interactive Internet-based audio/video transmission from classroom to classroom in multiple university-based PE programs. These Internet environments have been used in a variety of ways including: 1) forum for communication between the university faculty, students, and preceptors at clinical sites, 2) didactic lectures from expert clinicians to students assigned to distant clinical sites, 3) small group problem-based-learning modules designed to enhance students analytical skills, and 4) conversion of traditional face-to-face lectures to asynchronous learning modules. Hypotheses and measures of student and faculty satisfaction, clinical experience, and learning outcomes are proposed, and some early student feedback was collected. For curricula that emphasize both didactic and clinical education, the use of Internet-based VC and EMS software provides significant advancements over traditional models. Recognized advantages include: 1) improved communications between the college faculty and the students and clinical preceptors, 2) enhanced access to a national network of clinical experts in specialized techniques, 3) expanded opportunity for student distant clinical rotations with continued didactic course work, and 4) improved continuity and consistency of clinical experiences between students through implementation of asynchronous learning modules. Students recognize the learning efficiency of on

Discourse as mediator in environmental education in a natural science class: a case study

Directory of Open Access Journals (Sweden)

Marta Massa

2004-08-01

Full Text Available Discourse is an educational practice through which students and teachers are related by a sequence of meanings that are expressed, interchanged, negociated and constructed in the dynamic of a class. In this article, we analize the discursive practices and the arguments that are stated during a Science class when the teacher and her students discuss about the concepts “drinkable water – pollute water” when they are dealing with Environmental Education contents. A qualitative research within the perspective of a case study, centred on discourse analysis, was performed. We examine the content, the resources and the structural features that are used by the teacher and the students in order to construct the arguments and to establish the ideas. Two different templates were detected: the teacher’s, is based on perceptions and operative concepts, while the student’s one is organized in order to seek a microscopic explanation. Nevertheless, negotiation between these two perspectives fails during the dialogic interaction.

Time delay of the PeV gamma ray burst after the October 1985 radio flare of Cygnus X-3

Energy Technology Data Exchange (ETDEWEB)

1988-08-11

Cygnus X-3 remains a puzzling and controversial source of ultra-high-energy radiation, E greater than or equal to 0.1 PeV. In existing data, TeV and sometimes PeV radiation has been seen episodically; such an episode is connected with the radio flare of Cyg X-3 in October 1985, when PeV radiation with no phase structure was seen. The PeV pulse was detected 3-5 days after the radio flare. The author proposes a natural explanation for the delay, in which gamma-photons of PeV energy are absorbed by radio radiation inside the source. After a delay, the gamma radiation emerges as the radio flux diminishes and absorption decreases.

Full Text Available In this paper, using as a sample of 142 fourth-grade female pupils from three primary schools in Uzice and Pozega, their interests for physical education classes and the teaching contents in this subject have been examined. The results of the research point to the fact that the girls of this age are interested in basketball, handball and football. This fact should be considered when making the teaching curricula The results of the research point to the fact that the girls of this age like physiacal education and that it is their favourite school subject. On the basis of that fact it is possible to draw an indirect conclusion that the classes have been realized on the methodological level which presupposes obtaining the highest goal of physical education, and that is being involved in physical activity.

The physical activity (PA) levels of many children and adolescents in Australia are currently insufficient to promote health benefits. Physical education (PE) programs aim to promote PA and reach nearly all school-aged children, but PA levels within PE lessons are often low. PE teachers may influence children's motivation to be physically active in PE lessons, but little is known about teacher strategies that effectively motivate children to participate in PA, and few intervention studies have examined motivational strategies in PE. The purpose of this study was to compare the effect of three motivational strategies, each based on Self-Determination Theory (SDT), on PA levels, and their hypothesized antecedents, during year 8 PE lessons. This study employed a cluster-randomized controlled trial design. Following a familiarization session, PA levels and hypothesized PA antecedents were measured during a baseline lesson and a post-intervention or control lesson. Teachers (n = 16) and their classes from five secondary schools in Sydney, Australia were randomly assigned into four blocks and instructed to provide one of four 20-min lesson teaching strategy conditions: (1) explaining the relevance of activities; (2) providing choice from PA options selected by the teacher; (3) providing equipment and free choice of activities; or (4) usual practice. The primary outcomes were lesson time spent in moderate-to-vigorous PA, and motivation towards the lesson. Secondary outcomes were perceptions of teacher behavior, psychological needs satisfaction, and lesson time spent in sedentary behavior. PA and sedentary behavior were measured during baseline and post-intervention lessons with waist-mounted Actigraph GT3X accelerometers. Teacher behavior, psychological needs satisfaction, and motivation were assessed via questionnaires at the end of each lesson. Linear mixed-model analyses will be run on all outcomes, with students nested within teachers as a random effect. Study

The Peña Blanca region, 50 km north of Chihuahua City, Chihuahua, México, was a target of uranium exploration and mining by the Mexican government. After mining ceased in 1981, researchers became interested in this region as a study area for subsurface uranium migration with relevance to geologic disposal of nuclear waste. Many studies related to this concept were conducted at the Nopal I mine site located on a cuesta (hill) of the Sierra Peña Blanca. This site has geologic, tectonic, hydrologic, and geochemical similarities to Yucca Mountain, Nevada, a formerly proposed site for a high-level nuclear-waste repository in the unsaturated zone. The U.S. Department of Energy (U.S. DOE), Office of Civilian Radioactive Waste Management (OCRWM), sponsored studies at Nopal I in the 1990s and supported the drilling of three research wells – PB1, PB2, and PB3 – at the site in 2003. Beginning in 2004, the Peña Blanca Natural Analogue Project was undertaken by U.S. DOE, OCRWM to develop a three-dimensional conceptual model of the transport of uranium and its radiogenic daughter products at the Nopal I site.

Probing natural killer cell education by Ly49 receptor expression analysis and computational modelling in single MHC class I mice.

Directory of Open Access Journals (Sweden)

Sofia Johansson

Full Text Available Murine natural killer (NK cells express inhibitory Ly49 receptors for MHC class I molecules, which allows for "missing self" recognition of cells that downregulate MHC class I expression. During murine NK cell development, host MHC class I molecules impose an "educating impact" on the NK cell pool. As a result, mice with different MHC class I expression display different frequency distributions of Ly49 receptor combinations on NK cells. Two models have been put forward to explain this impact. The two-step selection model proposes a stochastic Ly49 receptor expression followed by selection for NK cells expressing appropriate receptor combinations. The sequential model, on the other hand, proposes that each NK cell sequentially expresses Ly49 receptors until an interaction of sufficient magnitude with self-class I MHC is reached for the NK cell to mature. With the aim to clarify which one of these models is most likely to reflect the actual biological process, we simulated the two educational schemes by mathematical modelling, and fitted the results to Ly49 expression patterns, which were analyzed in mice expressing single MHC class I molecules. Our results favour the two-step selection model over the sequential model. Furthermore, the MHC class I environment favoured maturation of NK cells expressing one or a few self receptors, suggesting a possible step of positive selection in NK cell education. Based on the predicted Ly49 binding preferences revealed by the model, we also propose, that Ly49 receptors are more promiscuous than previously thought in their interactions with MHC class I molecules, which was supported by functional studies of NK cell subsets expressing individual Ly49 receptors.

Many adolescents do not reach the recommended levels of physical activity (PA), and students attending vocational studies are less committed to take part in physical education (PE) than other students. The purpose of the present study was twofold: 1) to examine differences in physical activity, diet, smoking habits, sleep and screen time among Norwegian vocational high school students who selected either a PE model focusing on PA skills, technique and improvement of physical performance ("Sports enjoyment") or more on health, play and having fun when participating in PE lessons ("Motion enjoyment"), and 2) to explore the students' experiences with PE programs. In this mixed methods study 181 out of 220 invited students (82%) comprising 141 (78%) girls and 40 (22%) boys attending vocational studies of Restaurant and Food Processing (24%), Design, Arts and Crafts (27%) or Healthcare, Childhood and Youth Development (49%) were recruited for participation in the new PE program. PA level, sedentary time and sleep were objectively recorded using the SenseWear Armband Mini. A self-report questionnaire was used to assess dietary habits, smoking and snuffing habits, use of alcohol, screen use and active transportation. Four focus group interviews with 23 students (12 boys) were conducted to explore how the students experienced the new PE program. Students attending "Motion enjoyment" accrued less steps/day compared to the "Sports enjoyment" group (6661 (5514, 7808) vs.9167 (7945, 10390) steps/day) and reported higher screen use (mean, 3.1; 95% CI, 2.8, 3.5) vs. 2.4 (2.0, 2.9) hours/day). Compared to those attending "Sports enjoyment", a higher number of students attending "Motion enjoyment" reported an irregular meal pattern (adjusted odds ratio, 5.40; 95% confidence interval (CI), 2.28, 12.78), and being a current smoker (12.22 (1.62, 107.95)). The students participating in the focus group interviews emphasized the importance of having competent and engaging teachers

This study aims to evaluate the morphology and crystallization parameters of high density polyethylene (HDPE) with different concentrations of epoxy (DGEBA / OTBG), and the compatibility of this system was used and the copolymer polyethylene-block-poly (ethylene glycol) (PEG-co-PE). The blends were obtained by mechanical mixing on a torque rheometer (Haake). Determined the crystallization parameters of the test matrix differential scanning calorimetry (DSC) and by X-ray diffraction (XRD). The morphology of the system was analyzed by transmission electron microscopy (TEM). It was observed by XRD analysis that the addition of compatibilizer and epoxy resins do not interfere with the crystal structure of HDPE, indicating that the increase in crystallinity associated with the crystallization kinetics. It was observed that the compatibilizing helped the adhesion, reducing the size of the dispersed phase becomes a more stable morphology and obtaining a distribution of the dispersed epoxy phase.

The UV RESISTANCE LOCUS 8 (UVR8 protein is the first and only light photoreceptor characterized to date that is specific for UV-B light and it regulates various aspects of plant growth and development in response to UV-B light. Despite its involvement in the control of important plant traits, most studies on UV-B photoreceptors have focused on Arabidopsis and no data on UVR8 function are available for forest trees. In this study, we isolated a homologue of the UV receptor UVR8 of Arabidopsis, PeUVR8, from Populus euphratica (Euphrates poplar and analyzed its structure and function in detail. The deduced PeUVR8 amino acid sequence contained nine well-conserved regulator of chromosome condensation 1 (RCC1 repeats and the region 27 amino acids from the C terminus (C27 that interact with COP1 (CONSTITUTIVELY PHOTOMORPHOGENIC1. Secondary and tertiary structure analysis showed that PeUVR8 shares high similarity with the AtUVR8 protein from Arabidopsis thaliana. Using heterologous expression in Arabidopsis, we showed that PeUVR8 overexpression rescued the uvr8 mutant phenotype. In addition, PeUVR8 overexpression in wild-type background seedlings grown under UV-B light inhibited hypocotyl elongation and enhanced anthocyanin accumulation. Furthermore, we examined the interaction between PeUVR8 and AtCOP1 using a bimolecular fluorescence complementation (BiFC assay. Our data provide evidence that PeUVR8 plays important roles in the control of photomorphogenesis in planta.

Over the last decade sensitivity analysis techniques have been shown to be very useful to analyse complex and high dimensional Systems Biology models. However, many of the currently available toolboxes have either used parameter sampling, been focused on a restricted set of model observables of interest, studied optimisation of a objective function, or have not dealt with multiple simultaneous model parameter changes where the changes can be permanent or temporary. Here we introduce our new, freely downloadable toolbox, PeTTSy (Perturbation Theory Toolbox for Systems). PeTTSy is a package for MATLAB which implements a wide array of techniques for the perturbation theory and sensitivity analysis of large and complex ordinary differential equation (ODE) based models. PeTTSy is a comprehensive modelling framework that introduces a number of new approaches and that fully addresses analysis of oscillatory systems. It examines sensitivity analysis of the models to perturbations of parameters, where the perturbation timing, strength, length and overall shape can be controlled by the user. This can be done in a system-global setting, namely, the user can determine how many parameters to perturb, by how much and for how long. PeTTSy also offers the user the ability to explore the effect of the parameter perturbations on many different types of outputs: period, phase (timing of peak) and model solutions. PeTTSy can be employed on a wide range of mathematical models including free-running and forced oscillators and signalling systems. To enable experimental optimisation using the Fisher Information Matrix it efficiently allows one to combine multiple variants of a model (i.e. a model with multiple experimental conditions) in order to determine the value of new experiments. It is especially useful in the analysis of large and complex models involving many variables and parameters. PeTTSy is a comprehensive tool for analysing large and complex models of regulatory and

Full Text Available Rehabilitation system adopted by correctional facility is based on Pancasila. All incarcerated men are rehabilitated there with the goal to make them repent, be law-abiding citizens, and uphold moral values. Correctional facility comes as a rehabilitation place to improve social interaction so that inmates can be received by their social environment once they are released from prison. At this point, the researcher focuses on Islamic educational transformation through inmate social interaction training program at Palu correctional facility class II A. This research uses descriptive quantitative design with social legal approach to observe patterns of inmate social interaction. The result of research points out that Islamic educational transformation which is packed into rehabilitation programs and correctional educational activities is remarkably emphasized in inmate social interaction. In this case, Islamic educational transformation applied in Palu correctional facility class II A is defined as ultimum remidium, correctional activities emphasizing on process-based approach. Rehabilitation process given to inmates is able to improve insight and awareness of ethical and moral values in their social interaction. Therefore, when returning to society they can be accepted by social environtment as good responsible people.

The present work deals with the change in surface properties of polyethylene (PE) film using DC low pressure glow discharge air plasma and makes it useful for technical applications. The change in hydrophilicity of the modified PE film surface was investigated by measuring contact angle and surface energy as a function of exposure time. Changes in the morphological and chemical composition of PE films were analyzed by atomic force microscopy (AFM) and X-ray photoelectron spectroscopy (XPS). The improvement in adhesion was studied by measuring T-peel and lap-shear strength. The results show that the wettability and surface energy of the PE film has been improved due to the introduction of oxygen-containing polar groups and an increase in surface roughness. The XPS result clearly shows the increase in concentration of oxygen content and the formation of polar groups on the polymer surface. The AFM observation on PE film shows that the roughness of the surface increased due to plasma treatment. The above morphological and chemical changes enhanced the adhesive properties of the PE film surfaces, which was confirmed by T-peel and lap-shear tests.

2012-08-01

Despite evidence for the utility of self-determination theory in physical education, few studies used objective indicators of physical activity and mapped out between-class, relative to between-student, differences in physical activity. This study investigated whether moderate-to-vigorous physical activity (MVPA) and rated collective engagement in physical education were associated with autonomous motivation, controlled motivation, and amotivation at the between-class and between-student levels. Participants were 739 pupils (46.3% boys, Mage = 14.36 ±1.94) from 46 secondary school classes in Flanders (Belgium). Multilevel analyses indicated that 37% and 63% of the variance in MVPA was explained by between-student and between-class differences, respectively. Students' personal autonomous motivation related positively to MVPA. Average autonomous class motivation was positively related to between-class variation in MVPA and collective engagement. Average controlled class motivation and average class amotivation were negatively associated with collective engagement. The findings are discussed in light of self-determination theory's emphasis on quality of motivation.

2017-02-01

Historically high levels of economic inequality likely have important consequences for relationships between people of the same and different social class backgrounds. Here, we test the prediction that social affiliation among same-class partners is stronger at the extremes of the class spectrum, given that these groups are highly distinctive and most separated from others by institutional and economic forces. An internal meta-analysis of 4 studies (N = 723) provided support for this hypothesis. Participant and partner social class were interactively, rather than additively, associated with social affiliation, indexed by affiliative behaviors and emotions during structured laboratory interactions and in daily life. Further, response surface analyses revealed that paired upper or lower class partners generally affiliated more than average-class pairs. Analyses with separate class indices suggested that these patterns are driven more by parental income and subjective social class than by parental education. The findings illuminate the dynamics of same- and cross-class interactions, revealing that not all same-class interactions feature the same degree of affiliation. They also reveal the importance of studying social class from an intergroup perspective. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

This study aimed to investigate how were the peer and physical education (PE) teacher variables associated with moderate-to-vigorous physical activity (MVPA) among Kosovar teenagers (13-15 years of age), and the role of age and gender in these associations. Cross-sectional data was gathered through a study conducted in seven major municipalities of Kosovo. 632 girls (aged 14.3 ± 0.8) and 664 boys (aged 14.2 ± 0.8) were examined using the adjusted Classmate and Teacher Support Scale and the Physical Activity Screening measure. A three-way (support*age*gender) ANOVA was used to compare the individuals' MVPA level with the different levels of support they received, with different age in groups of girls and boys. Boys reported higher levels of MVPA than girls in all age categories. A higher level of MVPA was reported by boys receiving high or medium support from classmates. In case of PE teacher support, high, medium and even low support correlated with high MVPA in all age categories. In girls only 13 year olds reported receiving high levels of both classmate and PE teachers support which correlated with a higher level of MVPA. It appears that engagement in MVPA among young Kosovar adolescents is relatively high in boys, regardless of the level of classmate or PE teacher support, whereas in girls the level of MVPA decreased over their time at school. Support from both classmates and PE teachers turned out to be the most significant factor in 13 years old girls, before they moved from primary to secondary school. This issue requires more detailed insight, considering traditional ethnical and religious barriers to engagement of young female adolescents in physical activity.

Effects of ionizing radiation on the properties of ultra-high molecular weight polyethylene (PE-UHMW)

International Nuclear Information System (INIS)

Kurth, M.

1990-01-01

Ultra high molecular weight polyethylene (PE-UHMW) is used in most artificial joint replacement devices. Prior to implantation in biological environment, radiatin sterilization by 60 Co or electron beam is common. It is well known that polyethylene exposed to ionizing radiation of any sort undergo physical changes due to chain scission and/or crosslinking. PE-UHMW sheets, 8 mm thick, were either 60 Co or electron beam irradiated, in the range of 10-150 kGy under air or nitrogen atmoshere. The crystallinity of the irradiated samples increases with the irradiation dose. The chain scission/crosslinking events ratio determine the network structure and the sol/gel ratio. The latter was found to depend on irradiation dose, radiation atmosphere and sample thickness. Moreover 60 Co-irradiation is about 5 times more effective in forming PE-UHMW gel than electron-irradiation. Besides the degree of crosslinking, the molecular weight distribution is the main determinant of the structural properties of PE-UHMW. Low molecular weight fractions were also found. Using a dose of 30 kGy ( 60 Co in air), the average molecular weight of the soluble part after extraction decreased from originally 2.3 million g/mol to 170.000 g/mol, corresponding to a factor of about 10. These changes in molecular weight have a strong influence on the mechanical properties of PE-UHMW. Crosslinking slightly increases the yield strength, while the elongation at break decreases. Long-term compressive creep is reduced if the material is irradiated. Obviously, increased crystallinity after oxidative chain scission affects a higher deformation resistance. Radiation crosslinked structures cause a significant increase in abrasion resistance. The above described structural changes occur even upon irradiation of very low doses as used during sterilization. This study will enable to reduce the radiation sterilization damage and thus to gain long term stability of PE-UHMW medical devices. (orig./BBR)

Purpose: This study aimed to assess the striatal [ 18 F]FE-PE2I binding and the immunohistochemical stain of tyrosine hydroxylase (TH) in the striatum, and to evaluate the effects of therapeutic drugs on [ 18 F]FE-PE2I binding. Methods: Dynamic PET/CT of [ 18 F]FE-PE2I was performed in Parkinson’s disease (PD) rat models, induced by the unilateral injection of 6-OHDA into the striatum. A simplified reference tissue model method was used to calculate the striatal binding potential (striatal BP ND ). Each of the four normal rats was pretreated with pramipexole, amantadine, and escitalopram 30 min before [ 18 F]FE-PE2I injection. The effect of L-DOPA combined with benserazide was assessed in the normal and PD rats. Results: The BP ND was significantly lower in the lesioned striatum than in the striatum of the normal rats. After the pretreatment with pramipexole, amantadine, and escitalopram, the values of the striatal BP ND did not differ from those of the controls. The pretreatment with L-DOPA/benserazide, however, significantly reduced the striatal BP ND . The striatal BP ND of the PD rats with L-DOPA/benserazide pretreatment was not different from that of the same PD rats with placebo treatment. Conclusion: [ 18 F]FE-PE2I may be used as a radioligand for the in-vivo imaging of the DAT. In the normal rats, [ 18 F]FE-PE2I binding is unaffected by pramipexole, amantadine, and escitalopram. L-DOPA/benserazide does not affect the striatal [ 18 F]FE-PE2I binding in PD rats

Full Text Available Remitting seronegative symmetrical synovitis with pitting edema (RS3PE is a rare but well-reported clinical entity. It is classically described as symmetrical involvement of both upper extremities. Asymmetrical involvement had also been reported, but unilateral presentation is very rare. We hereby report a case of unilateral RS3PE in a patient of seronegative rheumatoid arthritis which was initially misdiagnosed as cellulitis and was given high dose antibiotics without any significant improvement. Later a rheumatologic consultation leads to a prompt diagnosis, and treatment with steroids leads to dramatic reversal of symptoms. This case demonstrates the rare presentation of this rare clinical entity and highlights the necessity of awareness regarding unilateral disease to clinicians.

Although the hypothalamus is classified into more than 10 compartments, it still contains uncharacterized areas. In this study, we identified a new triangular-shaped area between the paraventricular hypothalamic nucleus (PVN) and the fornix area in the mouse anterior hypothalamus, which is enriched in chondroitin sulfate proteoglycans (CSPGs). We designated this region as the perifornical area of the anterior hypothalamus (PeFAH) based on its anatomical location. As evidenced by Nissl staining, the PeFAH was distinguishable as an area of relatively low density. Immunohistochemical and DNA microarray analyses indicated that PeFAH contains sparsely distributed calretinin-positive neurons and densely clustered enkephalin-positive neurons. Furthermore, the PeFAH was shown to have bidirectional neural connections with the lateral septum. Indeed, we confirmed enkephalinergic projections from PeFAH neurons to the lateral septum, and inversely, calbindin-positive lateral septum neurons as afferents to the PeFAH. Finally, c-Fos expression analysis revealed that the activity of certain PeFAH neuronal populations tended to be increased by psychological stressors, but not that of enkephalinergic neurons. We proposed PeFAH as a new region in the AH.

Although there has been a long-standing debate about whether a single-sex or mixed-sex environment is better for students in many Western countries, coeducation is one of the taken-for-granted issues in the modern Turkish education system. This study examined commonly expressed concerns about gender equity in a mixed-sex environment within the context of physical education (PE) in Turkey. The purpose of the study was to examine teacher-student interaction in the coed PE classroom, focusing on gender-stereotyped beliefs. Participants consisted of two PE teachers and 37 eighth-grade students from a private school situated in suburban Ankara Turkey. The modified observational instrument with the combination of Teacher-Student Interaction (TSI) and Interactions for Sex Equity in Classroom Teaching Observation System (INTERSECT) was used to assess teacher-student interaction in the classroom. In order to understand students' and teachers' gender-stereotyped beliefs, individual interviews were also conducted. The findings of this study indicated that both male and female PE teachers interact more frequently with boys, and this interaction was influenced by gender-stereotyped beliefs of both teachers and students. In sum, similar to many other western countries, the movement toward coeducation in Turkey has not automatically brought equal opportunities for girls or boys in PE.

Is Queer Sex Education in Ontario Finally Out of the Closet?

Directory of Open Access Journals (Sweden)

Cameron McKenzie

2015-07-01

Full Text Available In 2010, Ontario’s Ministry of Education introduced a revised Health and Physical Education (H&PE curriculum that promised to be a vital health promotion initiative. Yet, after a minority conservative backlash, the Ontario government withdrew the sexual health sections from the elementary school curriculum, reverting it back to its 1998 content. This study is a content analysis, informed by queer theory and institutional ethnography, of the current and proposed H&PE documents, with a focus on the sex education component. This research aims to examine i the specific differences between the new and old H&PE documents with respect to referencing and delivering sex education, and more specifically sex education on queer/trans* issues; and ii the potential social exclusion that the absence of queer/trans* curriculum content imposes on youth. The findings demonstrate that evidence-informed policy development cannot always overcome political power imbalances, such as those created by the socially constructed ideology of heteronormativity. As the Ontario government prepares to implement the reformed curriculum, this study provides insight into its controversial history and the complexities of policy development—insights that may extend beyond this moment.

Abstract/Statement of the problem Skin disease research involving children currently faces several major hurdles and as a result, many therapies are only available for off-label use in children and many of the most pressing clinical needs of our pediatric population remain unsolved. A strategic planning committee of the Society for Pediatric Dermatology (SPD) identified the need for an organized, inclusive research alliance to augment the resources of individual practitioners and pre-existing smaller collaborative groups and facilitate robust, multicenter basic, translational, and clinical research and therapeutic trials. A December 2011 National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS) Roundtable on Pediatric Dermatology further detailed the therapeutic gaps and barriers to translation of scientific advances to clinical practice. Building on these forums, in July 2012, a group of interested investigators met in Monterey, CA to develop the infrastructure for collaborative pediatric skin research, now called the Pediatric Dermatology Research Alliance (PeDRA). The vision of PeDRA is to create sustainable collaborative research networks to better understand, prevent, treat and cure dermatologic diseases in children. From that starting point, subcommittees and expert members were added, stakeholders identified, and seed funding garnered, with the first PeDRA stand-alone research meeting* realized in Chicago, IL in October 2013.

Ponds and lakes are abundant in Arctic permafrost lowlands. They play an important role in Arctic wetland ecosystems by regulating carbon, water, and energy fluxes and providing freshwater habitats. However, ponds, i.e., waterbodies with surface areas smaller than 1. 0 × 104 m2, have not been inventoried on global and regional scales. The Permafrost Region Pond and Lake (PeRL) database presents the results of a circum-Arctic effort to map ponds and lakes from modern (2002–2013) high-resolution aerial and satellite imagery with a resolution of 5 m or better. The database also includes historical imagery from 1948 to 1965 with a resolution of 6 m or better. PeRL includes 69 maps covering a wide range of environmental conditions from tundra to boreal regions and from continuous to discontinuous permafrost zones. Waterbody maps are linked to regional permafrost landscape maps which provide information on permafrost extent, ground ice volume, geology, and lithology. This paper describes waterbody classification and accuracy, and presents statistics of waterbody distribution for each site. Maps of permafrost landscapes in Alaska, Canada, and Russia are used to extrapolate waterbody statistics from the site level to regional landscape units. PeRL presents pond and lake estimates for a total area of 1. 4 × 106 km2 across the Arctic, about 17 % of the Arctic lowland ( s.l.) land surface area. PeRL waterbodies with sizes of 1. 0 × 106 m2 down to 1. 0 × 102 m2 contributed up to 21 % to the total water fraction. Waterbody density ranged from 1. 0 × 10 to 9. 4 × 101 km−2. Ponds are the dominant waterbody type by number in all landscapes representing 45–99 % of the total waterbody number. The implementation of PeRL size distributions in land surface models will greatly improve the investigation and projection of surface inundation and carbon fluxes in permafrost lowlands.

In flipped-class pedagogy, students prepare themselves at home before lectures, often by watching short video clips of the course contents. The aim of this study was to investigate the effects of flipped classes on motivation and learning strategies in higher education using a controlled, pre- and posttest approach. The same students were followed in a traditional course and in a course in which flipped classes were substituted for part of the traditional lectures. On the basis of the validated Motivated Strategies for Learning Questionnaire (MSLQ), we found that flipped-class pedagogy enhanced the MSLQ components critical thinking, task value, and peer learning. However, the effects of flipped classes were not long-lasting. We therefore propose repeated use of flipped classes in a curriculum to make effects on metacognition and collaborative-learning strategies sustainable. PMID:26113628

The underassessment and undertreatment of pain in residents of long-term care (LTC) facilities has been well documented. Gaps in staff knowledge and inaccurate beliefs have been identified as contributors. To investigate the effectiveness of an expert-based continuing education program in pain assessment⁄management for LTC staff. Participants included 131 LTC staff members who were randomly assigned to either an interactive pain education (PE) program, which addressed gaps in knowledge such as medication management, or an interactive control program consisting of general dementia education without a specific clinical focus. Participants attended three sessions, each lasting 3 h, and completed measures of pain-related knowledge and attitudes⁄beliefs before, immediately after and two weeks following the program. Focus groups were conducted with a subset of participants to gauge perception of the training program and barriers to implementing pain-related strategies. Analysis using ANOVA revealed that PE participants demonstrated larger gains compared with control participants with regard to pain knowledge and pain beliefs. Barriers to implementing pain-related strategies certainly exist. Nonetheless, qualitative analyses demonstrated that PE participants reported that they overcame many of these barriers and used pain management strategies four times more frequently than control participants. Contrary to previous research, the present study found that the interactive PE program was effective in changing pain beliefs and improving knowledge. Continuing PE in LTC has the potential to address knowledge gaps among front-line LTC providers.

Water cycle research associated with the CaPE hydrometeorology project (CHymP

Duchon, Claude E.

1993-01-01

One outgrowth of the Convection and Precipitation/Electrification (CaPE) experiment that took place in central Florida during July and August 1991 was the creation of the CaPE Hydrometeorology Project (CHymP). The principal goal of this project is to investigate the daily water cycle of the CaPE experimental area by analyzing the numerous land and atmosphere in situ and remotely sensed data sets that were generated during the 40-days of observations. The water cycle comprises the atmospheric branch. In turn, the atmospheric branch comprises precipitation leaving the base of the atmospheric volume under study, evaporation and transpiration entering the base, the net horizontal fluxes of water vapor and cloud water through the volume and the conversion of water vapor to cloud water and vice-versa. The sum of these components results in a time rate of change in the water and liquid water (or ice) content of the atmospheric volume. The components of the land branch are precipitation input to and evaporation and transpiration output from the surface, net horizontal fluxes of surface and subsurface water, the sum of which results in a time rate of change in surface and subsurface water mass. The objective of CHymP is to estimate these components in order to determine the daily water budget for a selected area within the CaPE domain. This work began in earnest in the summer of 1992 and continues. Even estimating all the budget components for one day is a complex and time consuming task. The discussions below provides a short summary of the rainfall quality assessment procedures followed by a plan for estimating the horizontal moisture flux.

2010-03-01

This paper aims to study the profile of phospholipid (PL) classes of Iberian ham throughout its processing and the changes it underwent due to the influence of the pre-cure freezing treatment. The general profile of each PL class did not vary during the ripening stage. Phosphatidylcholine (PC) showed the highest proportion, followed by phosphatidyletanolamine (PE) and phosphatidylserine (PS) and phosphatidylinositol (PI) being the minor PL. The four PL classes were highly hydrolysed during the salting stage and their degradation continued during the rest of the processing. Pre-cure freezing of Iberian ham influenced the levels of the four PL classes at the initial stage, all of them being higher in refrigerated (R) than in pre-cure frozen (F) hams. Moreover, the pattern of hydrolysis was not the same in these two groups. Copyright 2009 Elsevier Ltd. All rights reserved.

Sibling correlations have gained increasing prominence in inequality studies as a Measurement of the total impact of family background on individual outcomes. Whilst previous studies have tended to use traditional socio-economic measures such as parent’s income or education, this paper introduces......’ education and income – include modifications of the Erikson–Goldthorpe–Portocarero schemes ranging from 3 to 15 classes and Grusky’s microclass scheme of 72 classes. The results show that although class adds to explanations of the family influence on children’s income, most of the sibling similarities...... are not explained by parental education, income or class. Depending on gender, the class schemes explain between 8 and 13 per cent of the sibling similarities and 15 to 20 per cent when parents’ income and educations are also included. Models with different class schemes demonstrate that elaborated versions...
