Seeing our Way into Learning

Recent developments in physics and neurobiology help explain recursive interactions between peripheral images and higher cortical centres that process symbolic representation. Seeing with focused attention to colour, line, depth and form, for example, gains meaning and understanding through this recursive process. Art as representation of constant, essential features of the external extends functions of the 'visual brain' to centres that bring perception to meaning and understanding that are interdependent with aesthetic sensibilities. Collaborative work through art enables verbal explication and explanation about details, abstractions and process that lead to theory building dependent on propositional, procedural and dispositional knowledge. The swirl of verbal, visual and gestural interactions that proceed out of engagement with multiple modes of representation ensures development of abilities to focus, strategise, discern and explicate components and integrate possibilities through future scenarios. The future curriculum needs to integrate visual, verbal and other representational modes as schools move closer in goals and process to non-school learning communities and organisations. Proposed here are ways to create an infrastructure for just such an ecology of learning environments that will link tightly with the information base of the new economy and the communicational needs of a civil society.     

Stress-Testing Europe: Normalizing the Post-Fukushima Crisis

The Fukushima accident was a crisis in Japan, and a crisis elsewhere. In Europe, the aftermath of Fukushima was a period of intense questioning, about how to ensure the safety of nuclear reactors, and how, at the same time, ensure the ability of the European Union to act as a consistent political actor in the face of potentially catastrophic risks. Using empirical material related to the post-Fukushima stress tests and the subsequent discussions about the European regulatory framework for nuclear safety, this paper shows that stress tests have provided a peculiar form of European intervention, restabilizing regulatory boundaries while extending the European gaze. It describes the overall operation thereby performed as the “normalization of the crisis” whereby the exceptional situation enters the realm of the normal functioning of the public administrations, and where the actions undertaken take the form of the legal norm.

     

The dangerousness of mountain recreation: A quantitative overview of fatal and non-fatal accidents in France

In France, there is a growing enthusiasm for outdoor sports and recreation. In the meantime, the risk of both severe and frequent injury associated with active pursuits in mountain areas is acknowledged. This paper tackles accidents related to mountain sports, with a focus on three critical activities: hiking, mountaineering and ski touring. The aim consists of estimating the actual number of accidents (whether they entailed deaths or injuries) in the three above-mentioned activities. In order to align the information collected, then provide estimations based on the reasoned crossing of these secondary data, we consulted and summarised all the databases available on the French territory. Results address the trauma-related mortality in absolute values, and a comparison with the death rate of other sports. The calculation of a mortality index, including secondary mortality, is then provided. Elements of mountain sports accidentality are also presented, intending to clarify how many casualities occur each year in the French mountains. Last, a focus on the particularities of each mountain sport is provided.     

Associations between physical activity and health-related fitness – volume versus pattern

Approximately 3.2 million people die of non-communicable diseases (NCD) each year due to insufficient physical activity. Physical activity guidelines are possibly perceived as too demanding and might thus pose a barrier. We addressed the question if a more stable physical activity pattern is associated with higher levels of health-related fitness than one with high and low intensities, regardless of the physical activity level (PAL). Physical activity was objectively measured in 296 men and women (53.7 ± 8.94 years) with the SenseWear Pro Armband^®. Using this data, the PAL and a Gini index were calculated to report the physical activity pattern. Health-related fitness was expressed as a fitness index. PAL was weakly correlated to health-related fitness (r = 0.38, P < .0001). The Gini index was also weakly correlated to the fitness index (r = 0.23, P < .0001). Results of the ANCOVA showed that participants in the first quartile of PAL always scored significantly lower for health-related fitness than participants in quartile four, after adjustment for the Gini index. These results suggest that as long as the volume of physical activity is high, health-related fitness will be high as well, independent of the physical activity pattern or variability in intensities throughout the day.     

Exploring Names and Identity Through Multicultural Literature in K-8 Classrooms

Children's names reflect their gender, culture, religion, language, and family history. Use of students' personal names has the power to positively affirm identity and signal belonging within the classroom and school community. However, naming practices also have the power to exclude, stereotype, or disadvantage students. For many students from diverse cultural and linguistic backgrounds, their names can be a source of cultural conflict and a watershed for issues of identity and belonging within the school setting. Through multicultural explorations of students' names, educators can affirm students' cultures and identities, and draw upon these as resources to support learning and development from early childhood through the adolescent years. The purpose of this article is to (a) discuss the importance of a person's name to cultural identity, (b) describe strategies to build multicultural communities in K-8 classrooms through exploration of students' names, and (c) suggest multicultural children's literature and curricular activities to teach about the importance of personal names, and develop cross-cultural understandings.     

Pioneering innovations in ultra-light mountain equipment: socio-technical analysis of two objects’ trajectories

The search to lighten material is a major trend accompanying the development of several sports and recreational mountain practices (ski touring, trail running, fast hiking, etc). Such characteristics as lightness, technicality, and durability are not easy to combine for the designers. Two emblematic inventions of this successful equation have drawn our attention (a climbing harness, and a backpack). We undertook a sociological analysis of these innovatory trajectories: in a socio-technical perspective, 15 semi-directive interviews have been conducted with partakers of the two innovations. Our results point out the complexity and unpredictability of such processes. These inventions are approved in the restricted circle of experienced outdoor professionals and practitioners; but in spite of this recognition, their attaining the status of innovation can be subject to debate, because of limited compromises, little broadening of the network, and a clear turn towards restrictive practices.     

Prediction of adult height in girls: the Beunen-Malina-Freitas method

The purpose of this study was to validate and cross-validate the Beunen-Malina-Freitas method for non-invasive prediction of adult height in girls. A sample of 420 girls aged 10-15 years from the Madeira Growth Study were measured at yearly intervals and then 8 years later. Anthropometric dimensions (lengths, breadths, circumferences, and skinfolds) were measured; skeletal age was assessed using the Tanner-Whitehouse 3 method and menarcheal status (present or absent) was recorded. Adult height was measured and predicted using stepwise, forward, and maximum R (2) regression techniques. Multiple correlations, mean differences, standard errors of prediction, and error boundaries were calculated. A sample of the Leuven Longitudinal Twin Study was used to cross-validate the regressions. Age-specific coefficients of determination (R (2)) between predicted and measured adult height varied between 0.57 and 0.96, while standard errors of prediction varied between 1.1 and 3.9 cm. The cross-validation confirmed the validity of the Beunen-Malina-Freitas method in girls aged 12-15 years, but at lower ages the cross-validation was less consistent. We conclude that the Beunen-Malina-Freitas method is valid for the prediction of adult height in girls aged 12-15 years. It is applicable to European populations or populations of European ancestry.     

Validation of the SenseWear Armband in different ambient temperatures

This study examines the validity of the SenseWear Armband in different temperatures using the old (SenseWear v2.2) and newest version of the algorithm (SenseWear v5.2) against indirect calorimetry (IC). Thirty-nine male and female students (21.1 ± 1.41 years) completed an exercise trial in 19°C, 26°C and 33°C consisting of 5 min standing followed by alternating walking/running at 35% and 65% of their maximal oxygen uptake. The accuracy of the algorithms was evaluated by comparing estimated energy expenditure (EE) to IC using a mixed-model design. No difference was reported in EE between the different temperatures for IC. Both algorithms estimated EE significantly higher when exercising at high intensity in 33°C compared to 19°C. Compared to IC, SenseWear v2.2 accurately estimated EE during standing and light intensity exercise but underestimated EE when exercising in a hot environment and at high intensity. SenseWear v5.2 showed a difference when exercising at high intensity in thermoneutral and warm conditions. The new algorithm improved EE estimation in hot environments and at high intensity compared to the old version. However, given the inherent inaccuracy of the EE estimates of SenseWear, greater weight should be given to direct monitor outputs rather than the ability of a monitor to estimate EE precisely.     

The influence of warning messages on the public's perception of substance use: A theoretical framework

We bring different theories together to develop a theoretical framework that helps to understand how early warning messages about (new) dangerous drugs can influence the public's perception of substance use. We bring together the agenda setting theory, framing theory, dual processing theory, social learning theory, health belief model, theory of planned behavior, and cultivation theory in order to explain how warning messages diffused through the mass media can have an impact on the receivers' perceptions. Based on these insights we construct the Integrated Media Effect Framework (IMFE) that takes into account the role of cultural and structural contexts in the realm of early warning systems (EWS). Ultimately, this framework provides valuable guidelines for conceptualizing EWS and for developing applications by governments.     

Methodological issues associated with longitudinal research: findings from the Leuven Longitudinal Study on Lifestyle, Fitness and Health (1969 - 2004)

Longitudinal studies provide unique opportunities but are also faced with several limitations. The purpose of this study was to document three of these issues ("imperfect" design, evolution of data collection methods, representativeness) by means of the Leuven Longitudinal Study on Lifestyle, Fitness and Health (LLSLFH). The LLSLFH (1969 - 2004) comprises observations on males between 12 and 18 years and at 30, 35, 40, and 47 years, and on females at 16 and 40 years. In the most recent phase of the study, spouses and offspring were also included. The different phases and evolving research questions throughout the LLSLFH required an appropriate adaptation of the research design. The associated evolution of data collection methods largely reflects the changing ideas about physical fitness, body composition, and physical activity, the continuing search for new and better measurement techniques, and the need for adaptations with age. Ongoing study participants are representative in terms of body composition and, except for adolescence in males, also physical activity. No straightforward answer can be given concerning physical fitness. In both sexes, socio-economic status is above average. When informed about the possible "pitfalls" of longitudinal research in advance, several measures could be taken to prevent or limit them as much as possible.
