Summary Based on ten years of fieldwork with a focus on macro-micro linkages from organizational ethos and structure to language behavior and roleplaying, this report centers on institutional changes that affect cognitive, social, and linguistic development of youth. Argued here is the resilience of those young people who find their way to youth-based (as distinct from youth-serving) organizations during their out-of-school lives. These organizations provide an institutional force to fill the voids left by intergenerational communication and nurturance breakdowns and an absence of meaningful work for youth in community and family life. Part 1 gives an overview of areas of interaction, work, and support that institutions fail to give in post-industrial societies and sets up the framework to view the fact that some youth create an institutional force through youth-based organizations that take over key socialization roles. Here crossage peers become their own agents to create an ecology of learning significantly different from customary agents of transmissive socialization. Part 2 answers the questions of what happens in this ecology of learning, and how learning works in youth-based organizations that place high emphasis on the real work of production and performance. Within these organizations that offer a type of liminal zone between childhood and full entry into adult life, youth take risks, play roles, and set their own rules in order to achieve a group goal of excellence in performance. Part 3 looks at language use within these organizations and addresses the means by which youth-based organizations remain dynamic and responsive to the rapidly changing dimensions of youth needs. Part 4 sets out certain changes necessary in the thinking of adults about models of socialization and their role in helping to make possible learning ecologies young people will see as effective. Part 5 pulls together the macro and micro dimensions of the findings to highlight the importance of research on the ways that rules, roles, and risks play within the work of learning.
Zusammenfassung Risiken, Regeln und Rollen. Jugendperspektiven zur Lernarbeit in der Gemeindeentwicklung Basierend auf zehn Jahren Feldforslchung mit dem Fokus auf den Makro-Mikro-Zusammenh?ngen zwischen organisationaler Struktur und dazugeh?rigem Ethos einerseits und Sprachverhalten und Rollenspiel andererseits konzentriert sich dieser Beitrag auf den institutionellen Wandel, der sich auf die kognitive, soziale und sprachliche Entwicklung der Jugend auswirkt. Auff?llig ist die Selbstbehauptungskraft derjenigen Jugendlichen, die in ihrer au?erschulischen Freizeit den Weg zu jugendzentrierten Einrichtungen finden. Diese Organisationen vermitteln eine institutionelle Macht, die die Leere der intergenerationellen Kommunikation, der Bildungsabbrüche und der fehlenden Aufgaben für Jugendliche im Familien- und Gemeindeleben füllt. Abschnitt 1 gibt zum einen einen überblick über Interaktionsbereiche, die Arbeit und Unterstützung, die Institutionen der postindustriellen Gesellschaft nicht geben, und zeigt dann auf, welche institutionelle Kraft manche Jugendliche durch Engagement in jugendzentrierten Initiativen entwickeln, denen Schlüsselfunktionen in ihrer Sozialisation zukommen. Hier werden altersgemischte Peergruppen ihre eigenen Interessenvertreter, um eigene Lernumgebungen zu schaffen, die sich signifikant von den herk?mmlichen, auf Stoffvermittlung bestehenden Ans?tzen unterscheiden. Teil 2 beantwortet die Fragen, was in diesen Lernumwelten geschieht und welch wichtigen Platz Lernen in diesen jugendzentrierten Einrichtungen mit ihrer deutlichen Betonung von ernsthafter produktorientierter Arbeit und Darstellung einnehmen. In diesen Projekten mit ihrem Angebot für den Zeitraum zwischen Kindheit und vollst?ndigem Eintritt in das Erwachsenenleben akzeptieren Jugendliche Risiken, spielen Rollen und setzen sich Regeln, um hervorragende Gruppenergebnisse, z. B. bei einer Theateraufführung, zu erreichen. Abschnitt 3 betrachtet die Sprache, die in diesen Organisationen benutzt wird, und benennt die Mittel, mit deren Hilfe jugendzentrierte Einrichtungen dynamisch bleiben und auf die raschen Wechsel der jugendlichen Bedürfnisse antworten. Teil 4 beschreibt einige notwendige ?nderungen im Denken der Erwachsenen hinsichtlich der Sozialisationsmodelle und beschreibt ihre Rolle für die effektive Gestaltung von Lernumgebungen für junge Menschen. Im fünften Abschnitt werden Forschungsergebnisse der Makro- und Mikroebene zusammengefasst, um die Wichtigkeit der Forschung zu unterstreichen, die darüber aufkl?rt, welche Rolle Regeln, Rollen und Risiken in der Lernarbeit spielen.

ABSTRACT

Previous studies investigating the relationship between motor skill, physical activity and fitness in children have not thoroughly considered the role of self-perception. Therefore, the study aim was to test a theoretical framework, which considered both actual and perceived motor skill as well as actual and perceived fitness. Potential moderating effects of sex and country were considered. Data on motor skill, fitness, as well as self-perception of motor skill and fitness were collected from 145 Australian children and 214 German children (age range 7 to 10 years). For actual motor skill and fitness, mean differences for sex, age and country were found. For perceived motor performance (perceived motor skill and perceived fitness) no mean differences were found for age. Path analyses were performed. The final model showed significant relations between actual performance (object control skill, fitness) and perceived performance (object control skill, fitness). All model paths had low to moderate regression weights with the lowest relationship reported between actual and perceived fitness. Sex and country showed no effects. This integrated approach has led to a better understanding of the relationship between children’s perceived and objective performance, and cultural differences within them.  相似文献

The dynamics and culture of families are central to individual and community sport and physical activity participation. This research project examined the lived experiences and day-to-day realities of the London 2012 Olympics from the perspectives of five families in the East Midlands region of England. The aims of the project were to assess the influence the Games had on shaping family sports participation, influencing social and health relationships within the families through sports and reactions to the 2012 Olympics. The study was conducted through the generation of rich qualitative data from pre- and post-Games interviews as well as production of video diary data by the families and young people themselves to gather micro-level information on the realities of ‘legacy’ for families. Findings from this research project illustrate that prior parental socialisation into sport shaped current attitudes to legacy and children and mothers and fathers had mixed reactions to the actual presence of legacy. There are also clear sports development challenges around accessibility, cost, project design, the non-family-friendly nature of some schemes present during the potential consumption of legacy that have consequences for future research in this embryonic area. Implications from the study include the need to locate the family as a more central concern for policy makers in sports development practice. The study has questioned the assumed virtuous legacy of the London 2012 Games from the perspective of families on a day-to-day micro-level. Instead, a far more complex and diverse picture from the perspective of the family has been presented that requires further critical research on this little explored topic of policy and practice in sports development.  相似文献

This study examined how doulas adapt to challenges in client’s labors. There were 104 Canadian and 92 American doulas who responded to a survey distributed at a doula conference. We report results from open-ended questions in which doulas describe how they manage changes deviating from the mother’s birth plan and how they navigate differences of opinion between themselves and providers. Four themes emerged: giving nonjudgmental support, assisting informed decision making, acting as a facilitator, and issues with advocacy. Although 30% of doulas said that advocacy and information giving could result in conflict with providers, doulas reported working within their scope of practice and striving to be part of the team. Issues in doula responsibility and patient advocacy remain, and ongoing role clarification is needed.  相似文献

Grade retention and inequalities that derive from grade retention can influence student school trajectories and careers. Grade retention can discourage students from education, and increase school failure and dropout. This study explored the relationship between grade retention and student intentions to enrol in higher education. We also studied the role of school identification and behavioural engagement in this relationship. The analysis is based on a sample of 1,089 students (grades 6 to 10) from Portugal, one of the European countries with the highest rates of grade retention. We employed multilevel probit regression modelling with random intercept and fixed slopes to explore both the individual and school level effects of grade retention. The analyses showed that retained students had a lower probability of intent to enrol in higher education and that there was a contextual effect of the number of retained students in the school, on students' probability of intent to enrol in higher education. This association was partially explained at the individual level by students' school identification. Retained students presented lower levels of school identification, which in turn results in lower probabilities of enrolling in higher education. Student behavioural engagement was not associated with grade retention nor student intentions. Our findings suggest the need for interventions that foster students' school identification to overcome the adverse effects of grade retention.  相似文献

Proximity effects on the dynamics and outcomes of scientific collaborations   总被引:1,自引:0,他引:1  
This paper uses path overlap, an innovative measure of functional proximity, to examine how physical space shaped the formation and success of scientific collaborations among the occupants of two academic research buildings. We use research administration data on human subject protection, animal use management, and grant funding applications to construct new measures of collaboration formation and success. The “functional zones” investigators occupy in their buildings are defined by the shortest walking paths among assigned laboratory and office spaces, and the nearest elevators, stairs, and restrooms. When two investigators traverse paths with greater overlap, both their propensity to form new collaborations and to win grant funding for their joint work increase. This effect is robust across two very differently configured buildings. Implications for scientific collaboration and the design and allocation of research space are considered.  相似文献
