ABSTRACTAlthough preceded by years of political and policy developments, the signing of the Good Friday Agreement (or Belfast Agreement) in 1998 is generally regarded as marking the end of conflict and the beginning of the transition to peace. However, this transition has been neither linear nor straightforward. Divisions, both physical and symbolic, reflecting collective identities and ‘otherness’, remain resistant to change and continue to foster sectarianism, mistrust and outbreaks of violence. Despite some positive change, not least of which is the absence of sustained violence, the majority of neighbourhoods and schools remain either Protestant or Catholic. Drawing on data from the Young Life and Times (YLT) survey, an annual attitudinal survey of 16-year-olds in Northern Ireland that has been running since 2003, this article explores what young people's perspectives reveal about the complexities and the challenges involved in transitioning to a more shared society. Where relevant and possible, their attitudes are compared with those expressed by adults in the annual Northern Ireland Life and Times (NILT) survey. A primary focus on tracking teenagers' attitudes is important for a number of reasons. While often regarded as a ‘post-conflict’ generation, segregation and polarisation remain features of teenagers' everyday lives and the political landscape. Children and young people are one of the four key strategic priorities in the latest government strategies to build united communities and achieve change and are embedded in the Programme for Government 2016–2021. If these government commitments are to be realised, the voices of young people must become central rather than peripheral. It is important, therefore, that their opinions are not only sought, but also interrogated and fed into policy. 相似文献

Objectives: To improve well-being and performance indicators in a group of Australian Football League (AFL) players via a six-week sleep optimisation programme. Design: Prospective intervention study following observations suggestive of reduced sleep and excessive daytime sleepiness in an AFL group. Methods: Athletes from the Adelaide Football Club were invited to participate if they had played AFL senior-level football for 1–5 years, or if they had excessive daytime sleepiness (Epworth Sleepiness Scale [ESS] >10), measured via ESS. An initial education session explained normal sleep needs, and how to achieve increased sleep duration and quality. Participants (n?=?25) received ongoing feedback on their sleep, and a mid-programme education and feedback session. Sleep duration, quality and related outcomes were measured during week one and at the conclusion of the six-week intervention period using sleep diaries, actigraphy, ESS, Pittsburgh Sleep Quality Index, Profile of Mood States, Training Distress Scale, Perceived Stress Scale and the Psychomotor Vigilance Task. Results: Sleep diaries demonstrated an increase in total sleep time of approximately 20?min (498.8?±?53.8 to 518.7?±?34.3; p?<?.05) and a 2% increase in sleep efficiency (p?<?0.05). There was a corresponding increase in vigour (p?<?0.001) and decrease in fatigue (p?<?0.05). Conclusions: Improvements in measures of sleep efficiency, fatigue and vigour indicate that a sleep optimisation programme may improve athletes’ well-being. More research is required into the effects of sleep optimisation on athletic performance. 相似文献

With reference to the recent science studies debate on the nature of science-industry relationship, this article focuses on
a novel organizational form: the technological platform. Considering the field of micro- and nanotechnology in Switzerland,
it investigates how technological platforms participate in framing science-industry activities. On the basis of a comparative
analysis of three technological platforms, it shows that the platforms relate distinctly to academic and to industrial users.
It distinguishes three pairs of user models, one model in each pair pertaining to how platforms act toward and conceive of
academic users, the other model regarding users from industry. The article then discusses how technological platforms reconfigure
the science-economy divide. While the observed platforms provide new institutional contact and interaction between academia and industry, new research collaboration does not necessarily materialize in practice. In this respect, science-industry mediation by way of technological platforms does not make science-industry boundaries
more porous. Instead, the declared openness of public research with respect to industry, in the case of technological platforms,
may contribute to maintain public science’s autonomy. 相似文献

It is a rather safe statement to claim that the social dimensions of the scientific process are accepted in a fair share of studies in the philosophy of science. It is a somewhat safe statement to claim that the social dimensions are now seen as an essential element in the understanding of what human cognition is and how it functions. But it would be a rather unsafe statement to claim that the social is fully accepted in the philosophy of mathematics. And we are not quite sure what kind of statement it is to claim that the social dimensions in theories of mathematics education are becoming more prominent, compared to the psychological dimensions. In our contribution we will focus, after a brief presentation of the above claims, on this particular domain to understand the successes and failures of the development of theories of mathematics education that focus on the social and not primarily on the psychological. 相似文献

Abstract The incidence of aggression and violence in schools is approaching epidemic proportions. Unfortunately, few teacher education programs offer coursework designed to prepare school personnel to face the mounting challenge of student aggression. Drawing upon the accumulated literature, changes are discussed in the content of teacher education programs that would prepare teachers to effectively address student violence. Assertions are made that colleges of education must assume leadership roles in redefining professional boundaries to prepare all school personnel to combat student aggression. Lastly, arguments are presented for strengthening university and public school collaboration to promote programs designed to curb the rising tide of student aggression and violence. 相似文献

The analysis of longitudinal data in education is becoming more prevalent given the nature of testing systems constructed for No Child Left Behind Act (NCLB). However, constructing the longitudinal data files remains a significant challenge. Students move into new schools, but in many cases the unique identifiers (ID) that should remain constant for each student change. As a result, different students frequently share the same ID, and merging records for an ID that is erroneously assigned to different students clearly becomes problematic. In small data sets, quality assurance of the merge can proceed through human reviews of the data to ensure all merged records are properly joined. However, in data sets with hundreds of thousands of cases, quality assurance via human review is impossible. While the record linkage literature has many applications in other disciplines, the educational measurement literature lacks details of formal protocols that can be used for quality assurance procedures for longitudinal data files. This article presents an empirical quality assurance procedure that may be used to verify the integrity of the merges performed for longitudinal analysis. We also discuss possible extensions that would permit merges to occur even when unique identifiers are not available. 相似文献

The article examines the theory and practice of focus groups in adult education research. Three theoretical positions are described: radical hermeneutic, moderate interpretative and pragmatic realistic position trying to bridge the gap with positivist research. This last position has been chosen as the departure point for a further analysis of the focus group elements, which relate to validity and reliability. The research examines four European research projects in the field of adult education. The most important and surprising data are presented with reference to both socio-psychological and technical problems in the use of this method. The results highlight the importance and dynamics of all the elements discussed. 相似文献

Biodiversity is an emerging theme in science, society and, more recently, education. There is no one single definition of biodiversity that is adequate in all situations. Both the knowledge base and the value base of biodiversity are variable and questionable. Because of these characteristics, biodiversity makes for an interesting vehicle for linking science and society, and the investigation of the normative underpinnings of 'science-in-the making'. Based on a 3-year study, this paper explores the crossroads between science education and environmental education and presents a framework for tapping the environmental education potential of biodiversity. Outlined are a number stepping stones for making biodiversity meaningful to learners. It is argued that, from the perspective of environmental education, the illdefined nature of biodiversity is a useful feature. Biodiversity is renewing the discourse on nature conservation issues by bringing together different groups in society that are searching for a common language to discuss nature conservation issues in relation to sustainability issues. The resulting debate allows the socio-scientific dispute character of 'science-in-the-making' to surface. Participation in such a dispute is an excellent opportunity to learn about a highly relevant, controversial, emotionally charged and debatable topic at the crossroads of science, technology and society 相似文献

Five women and 5 men were studied to examine the effects of submaximal exercise on thermoregulatory and hemodynamic variables during recovery in two environments: (a) control (C), 22 degrees C, 33% rh; and (b) hot humid (H), 32 degrees C. The participants exercised on a cycle ergometer at 60% of peak oxygen consumption for 35 min prior to 90 min of seated recovery. Sessions were identical, except for environment. Variables evaluated (p < .05) were: core temperature (TR), mean skin temperature (Ts), sweat rate (SR), heart rate (HR), stroke index (SI), cardiac index (CI), forearm blood flow (FBF), systolic blood pressure (SBP), and diastolic blood pressure (DBP). Men and women exhibited similar patterns of TR, Ts, and SR in both environments. Ts and SR (collapsed means for gender) were higher in the H than in the C. DBP was higher in men than in women throughout recovery in both environments. With combined means for gender, HR was higher in the H than in the C. CI, SI, FBF, and SBP were similar in both environments and returned to baseline within 15 min into recovery. These data suggest that heat dissipation during extended recovery was accomplished with similar contributions of cutaneous vasodilation and sweating in M and F. Furthermore, the moderate exercise level did not influence hemodynamics beyond 15 min of recovery in either environment. 相似文献
