Developing children: developmental discourses underpinning physical education at three Scottish preschool settings

This paper reports on one aspect of a study that investigated the place and meaning of ‘physical education’ to practitioners and children at three preschool settings in Scotland. We employed a poststructural type of discourse analysis to examine the developmental discourses the 14 participating practitioners drew on when talking about ‘physical education’ at preschools, during semi-structured interviews. Three main discourses around the notion of developmentalism were identified during analysis of the adults’ interview data: (1) preschool children learn and develop through play; (2) preschool children should have choices and freedom and (3) sometimes more structured activities are needed. The practitioners were heavily invested in developmental ‘truths’ about how preschool children learn and develop. They were in agreement that play is a vital element of preschool education, and that, consequently, children should be provided with opportunities for exploration and making choices. However, they also talked about sometimes ‘needing’ to restrict children's freedom and provide more adult-led activities. Our findings illustrate the strength of developmental discourses at the three settings. We suggest that preschool practitioners, as well as policy-makers and researchers, should critically reflect on the effects of taken-for-granted developmental discourses and move beyond thinking in terms of binaries such as ‘physical education versus play’ or ‘structure versus freedom’.     

Pupils’ (II ‐ 12 year olds) conceptions of combustion

This study relates to the teaching of combustion in the first year of French secondary education (11‐12 years of age). The area of particular interest was to investigate to what extent a study of combustion makes it possible to introduce concepts relative to chemical reactions.

Data were collected before teaching and during teaching sessions by means of written replies to questionnaires, interviews, and tape‐recording of the sessions. Over 400 pupils were questioned. The results show that the observations made by the students lead them to interpretations which are far removed from concepts of a chemical reaction between a combustible and oxygen. The modification of properties of an object during a combustion results from separate transformations of each of the substances composing the object. Permanent nature of some substances is asserted, made good by the conservation of some properties (colour, smell, for example).

These results have immediate pedagogical implications and indicate the necessity of redefining the objectives of such teaching.     

Reliability and Validity of the Flemish Physical Activity Computerized Questionnaire in Adults

The purpose of this study was to investigate the test-retest reliability and concurrent validity of the Flemish Physical Activity Computerized Questionnaire (FPACQ) in employed/unemployed and retired people. The FPACQ was developed to assess detailed information on several dimensions of physical activity and sedentary behavior over a usual week. A triaxial accelerometer, the RT3 Triaxial Research Tracker (RT3), in combination with a written 7-day activity record, was used as the objective criterion measure. In employed/unemployed people, 2-week test-retest reliability for several activity variables calculated from the FPACQ was good to excellent with intraclass correlations (ICCs) ranging from .67 to .99. In retired people ICCs were lower but, except for time spent eating, still fair to excellent, ranging from .57 to .96. Except for time spent in leisure time activities for men and the average energy expenditure related to sports participation in women, correlations between the RT3 and the FPACQ generally supported the relative validity of the FPACQ for employed/unemployed people (r ranging from .37 to .88). Values for retired people were somewhat lower (r ranging from .15 to .85), but most variables still reached at least moderate correlations. Concerning absolute validity, the FPACQ generally overestimated physical activity and underestimated sedentary behavior compared to the RT3. From this study, it can be concluded that the FPACQ is a reliable and reasonably valid questionnaire for assessing different dimensions of physical activity and sedentary behavior.     

Evaluation of a group intervention using a feminist approach for women experiencing sexual abuse

OBJECTIVE: The present study evaluates a group intervention using a feminist approach for women experiencing sexual abuse in childhood or adulthood in order to measure changes associated with participation in a group intervention and verifies whether effects are maintained over time. The present study relates effects of the group intervention in terms of psychological distress, depression symptoms, post-traumatic stress symptoms and feelings of guilt and helplessness. METHOD: The sample consists of 26 women participating in a group intervention offered by sexual assault centers in Quebec (CALACS - Centre d'aide et de lutte contre les agressions à caractère sexuel). RESULTS: Results show significant differences between pretest and post-test scores obtained one week following the end of the group intervention and gains are maintained at follow-up 3 months later. CONCLUSION: The findings suggest that participation in the group intervention is associated with a reduction of psychological distress, depression symptoms, post-traumatic stress symptoms and feelings of guilt and helplessness in adult women reporting sexual abuse.

The role of location and social strength for friendship prediction in location-based social networks

Recent advances in data mining and machine learning techniques are focused on exploiting location data. These advances, combined with the increased availability of location-acquisition technology, have encouraged social networking services to offer to their users different ways to share their location information. These social networks, called location-based social networks (LBSNs), have attracted millions of users and the attention of the research community. One fundamental task in the LBSN context is the friendship prediction due to its role in different applications such as recommendation systems. In the literature exists a variety of friendship prediction methods for LBSNs, but most of them give more importance to the location information of users and disregard the strength of relationships existing between these users. The contributions of this article are threefold, we: 1) carried out a comprehensive survey of methods for friendship prediction in LBSNs and proposed a taxonomy to organize the existing methods; 2) put forward a proposal of five new methods addressing gaps identified in our survey while striving to find a balance between optimizing computational resources and improving the predictive power; and 3) used a comprehensive evaluation to quantify the prediction abilities of ten current methods and our five proposals and selected the top-5 friendship prediction methods for LBSNs. We thus present a general panorama of friendship prediction task in the LBSN domain with balanced depth so as to facilitate research and real-world application design regarding this important issue.
