The match demands of international rugby sevens

The purpose of this study was to quantify the global match demands of international rugby sevens and to compare the match demands of forwards and backs, and between tournament rounds. To assess the match demands, global positioning system (GPS) and video analysis were collected from 27 international rugby sevens players from the same team across an entire International Rugby Board Sevens World Series season. Differences in running demands and match activities between forwards and backs were mostly trivial and small (ES = 0.05–0.84) while differences in running demands and match activities between Pool and Cup rounds were trivial (ES = 0.001–0.12). Cup round matches showed an increase in long-duration ball-in-play sequences (proportion ratio 0.46). These findings suggest international rugby sevens forwards and backs experience similar match demands while overall match demands remain consistent across tournament rounds.     

The Joinville School and the Institutionalization of a French-Style Physical Education, 1852–1939

Since the mid-nineteenth century, the Joinville School in France has worked to promote an innovative method of physical education, the French method, which was strongly marked by ideological and geopolitical challenges. Most of the French actors, whether they be military, doctors, scientists, or teachers, fought to defend France on the move. Physical education and its scholastic responsibility thus represented an original means to serve the national community and to give the country the necessary influence it required on the political and cultural international scene. If during the Second Empire, the Joinville School participated in the development of the physical instruction of French troops, during the third Republic, this officers' training school expanded the promotion of its method for physical education in schools. Among the challenges of this strategy, the actors for French physical education were faced with the organization of a common national teaching method as additional support for the promotion of a method that bore the mark of an eclectic philosophy. Until World War II, the Joinville School was a center for innovation that would spread practical physical education throughout France and Europe.     

Materials and techniques: Early Buddhist wall paintings and sculptures at Sumda Chun,Ladakh

An assemblage of Buddhist wall paintings and sculptures dating to the twelfth/early thirteenth century are found distributed over the interiors of the temple complex at Sumda Chun, Ladakh. Detailed investigations carried out as part of a conservation project shed light on their antiquity and production technology. The sculptures are constructed with fine mud mortar applied over a wooden armature and affixed to the walls without any support from the ground. In both the sculptures and wall paintings, the paint layer is applied over a thin gypsum ground that functions as a white colourant where unpainted. For the paint layer, azurite, vermilion, and orpiment are the dominant mineral pigments utilized. Minium (red lead) has been used for preparatory drawings and as paint. Highlighting of special areas was achieved using a laminate of tin–lead alloy and gold on relief. Overall the material and techniques employed in the execution of the wall paintings and sculptures are consistent with those reported for other early sites in the region.     

The Undressed Newsroom

Rapidly changing working conditions in recent years, along with the need to reduce the costs of news production, require journalists to adapt. Our suggestion here is that many of the research methods for analysing journalists' work environments to date are no longer sufficient for capturing this ongoing change. In searching for new approaches to analysis of the journalistic environment, we decided to apply visual ethnography, a method not yet used in the Czech Republic and not much used in the world beyond. For our pilot study of Czech newsrooms, we worked with both photographs taken of the journalists involved in our project and photographs taken by our research team (photographs showed both journalists' working conditions and working processes). We then interviewed the journalists about the photographs and more widely about their working practices and conditions. This paper presents the results of the research but also considers the advantages and challenges of the visual ethnographic approach and its implementation in media environments.     

Current Developments in Community College Performance Funding

Since the initiation of performance funding in Tennessee in the late 1970s, approximately 30 states have, at some point, attempted a funding model that includes performance on a set of indicators. The purpose of the present study was to capture the current status of performance funding in public statewide community college systems and to assess which performance indicators were collected at the state level. Data were obtained through the 2012 Survey of Finance and Access Issues conducted by the Education Policy Center at the University of Alabama. The survey was administered to the National Council of State Directors of Community Colleges, and 50 responses were obtained from 49 states. Not every survey respondent answered each survey item. Findings showed that 19 states used performance funding for community colleges, with six of those states allocating at least 10% of state funds based on performance. An analysis of indicators captured at the state level (not exclusively for performance funding) showed a decline of emphasis on process indicators and greater emphasis on outputs. The performance-based distribution of base funding and the inclusion of output measures that capture intermediate indicators of success are consistent with the principles of Performance Funding 2.0, a new form of performance funding recently discussed in the literature. Future research should include tracking the current findings over time and expanding the existing literature on whether performance funding influences outcomes.     

Effect of Resveratrol and Nicotine on PON1 Gene Expression: In Vitro Study

Dietary and lifestyle factors have been shown to have a profound effect on paraoxonase-1 (PON1) activity. Cigarette smoke has been shown to inhibit its mass and activity where as resveratrol has been shown to enhance it. We exposed hepatoma derived cell line (HepG2) to resveratrol and nicotine in varying doses and measured PON1 enzymatic activity and PON1 gene expression. In addition, total protein content of HepG2 cells was also measured. Resveratrol in a dose of 15 μmol/l or above significantly increased the PON1 enzyme activity (p > 0.001) where as nicotine in a dose of 1 μmol/l or higher significantly reduced it (p < 0.05). The resveratrol in this dose also enhanced the PON1 gene expression whereas nicotine decreased it as compared to controls. However, the protein conent of cells was not changed suggesting that they were not cytotoxic in the doses used. Till date the antioxidant vitamins have shown disappointing results against LDL oxidation and cardiovascular protection. However, the effect of resveratrol on PON1 gene expression and activity was significant, suggesting increase in PON1 activity and enhanced gene expression may be its alternative mechanism for offering protection against cardiovascular disease and may be an potential pharmacological agent which can be used for this.     

Separation of platelets from other blood cells in continuous-flow by dielectrophoresis field-flow-fractionation

We present a microfluidic device capable of separating platelets from other blood cells in continuous flow using dielectrophoresis field-flow-fractionation. The use of hydrodynamic focusing in combination with the application of a dielectrophoretic force allows the separation of platelets from red blood cells due to their size difference. The theoretical cell trajectory has been calculated by numerical simulations of the electrical field and flow speed, and is in agreement with the experimental results. The proposed device uses the so-called "liquid electrodes" design and can be used with low applied voltages, as low as 10 V(pp). The obtained separation is very efficient, the device being able to achieve a very high purity of platelets of 98.8% with less than 2% cell loss. Its low-voltage operation makes it particularly suitable for point-of-care applications. It could further be used for the separation of other cell types based on their size difference, as well as in combination with other sorting techniques to separate multiple cell populations from each other.     

The harmful aspect of teacher conditional support on students’ self-perception of school competence

When children perceive a conditional support, they only feel loved and encouraged for their ability to meet others’ standards. This may lead them to develop high sensitivity to errors and anxiety and low perception of competence. In this study, we examined the relationship between the perceived conditional support from teacher and children’s self-perception of school competence. We tested the mediating effect of sensitivity to errors and test anxiety in the relationship between teacher conditional support and children’s perception of school competence. Participants were 524 elementary school students (aged 9–10 years). The results showed that the greater the extent to which the children perceived conditional support from their teacher, the lower their self-perceived scholastic competence. They also confirm that this relationship was mediated by sensitivity to errors and test anxiety.     

Etude en temps réel de la production eEcrite chez des enfants de sept et huit ans

The aim of this research is to study on-line written production in children. Twelve seven year old children and twelve eight year old children were asked to compose two texts (a narrative and a report). They were filmed as they wrote in order to investigate the temporal caracteristics of their composition (pauses, rates…). The results show three main findings:

- the rates increases from seven to eight year old.

- pauses times varied according to the syntactic organisation of the next sentence.

- longer pause times are localized after punctuation marks and before connective.

     

Modifying vocational education curricula to accommodate handicapped learners: combining the efforts of special and vocational teachers

A systems approach to modifying existing vocational curricula to meet the needs of handicapped learners is presented. The roles of both special and vocational educators at each level of the modification process are discussed, together with the process as it is applied to a component of agricultural education. A significant amount of instructional technology is necessary to successfully integrate many handicapped learners into the regular vocational education environment: vocational education for handicapped persons needs to move from the stage of awareness to that of implementation.
