Sandra Taylor 《British Journal of Sociology of Education》1986,7(4):379-395
This paper examines the impact of economic recession and high unemployment on teenage girls’ subcultures in Australia. It is argued that the tensions between domestic roles and economic roles, which are experienced by young women, have been exacerbated by recent changes in the economic context. A number of general cultural responses to this context are then discussed, followed by a more specific focus on the issue of teenage ‘welfare mothers’.
It is argued that both economic and cultural factors shape young working‐class women's life experience and reinforce dependency, through marriage or welfare. Education and youth policies have failed to benefit these young women, who are still disadvantaged in the labour market. Currently there is evidence that they are more likely than ever to be leading lonely, isolated and dependent lives, and without policies which specifically meet the needs of young working‐class women there is unlikely to be much change in the future. 相似文献

A Global Developmental Trend in Cognitive Processing Speed 总被引:5,自引:1,他引:5
Sandra Hale 《Child development》1990,61(3):653-663
Children respond more slowly than young adults on a variety of information-processing tasks. The global trend hypothesis posits that processing speed changes as a function of age, and that all component processes change at the same rate. A unique prediction of this hypothesis is that the overall response latencies of children of a particular age should be predictable from the latencies of young adults performing the same tasks--without regard to the specific componential makeup of the task. The current effort tested this prediction by examining the performance of 4 age groups (10-, 12-, 15-, and 19-year-olds) on 4 different tasks (choice reaction time, letter matching, mental rotation, and abstract matching). An analysis that simultaneously examined performance on all 4 tasks provided strong support for the global trend hypothesis. By plotting each child group's performance on all 4 tasks as a function of the young adult group's performance in the corresponding task conditions, precise linear functions were revealed: 10-year-olds were approximately 1.8 times slower than young adults on all tasks, and 12-year-olds were approximately 1.5 times slower, whereas 15-year-olds appeared to process information as fast as young adults. 相似文献

In South Africa the education system for black children is fraught with problems. These problems are the direct result of apartheid and have been compounded by poverty and illiteracy. In this article the problem of poorly qualified or unqualified teachers is discussed especially with regard to the teaching of map skills to children in their fifth school year. The project team needed to develop affordable materials which could be used in large classes by teachers after a very short period of training. Books and other materials which are available commercially were examined, but for various reasons were found to be unsuitable for local conditions. After determining the extent of the problem, the project team followed a grassroots process of developing a flip chart which teachers learnt to use with confidence and which enabled pupils to master the concepts and skills necessary for understanding a map. 相似文献

Objective:The primary objective of this study was to determine how community college health sciences librarians perceive their proficiencies in the essential skills, knowledge, and abilities necessary for the practice of a health information professional as defined by the Medical Library Association (MLA) Competencies for Lifelong Learning and Professional Success. A secondary objective was to determine their current level of engagement with the professional community and identify barriers to further professional development.Methods:A survey was posted to various email discussion lists, and volunteer follow-up interviews were conducted.Results:The survey was completed by seventy-five community college health sciences librarians, and seven follow-up interviews were performed. Survey results indicated that community college health sciences librarians perceived themselves as having intermediate or advanced intermediate proficiency in the six MLA competencies. Survey and interview results indicated that community college health sciences librarians were engaged with the profession and faced the same barriers to continued professional development and continued education as other academic librarians.Conclusion:The results affirm that community college librarians who are responsible for collections and services in the health sciences meet the MLA competencies, which fills a gap in the literature regarding how these librarians develop professional competencies and are involved in professional associations. The results suggest that community college librarians can improve their skill levels by continuing their education and following trends in the literature. 相似文献

Downs DS Graham GM Yang S Bargainnier S Vasil J 《Research quarterly for exercise and sport》2006,77(1):91-99
The study purposes were to examine: (a) the determinants of exercise intention and past exercise behavior (PEB) using the theories of reasoned action and planned behavior, and (b) the moderating influences of sex and exercise group (meeting or not meeting exercise guidelines). Participants (n = 676 adolescents) completed self-reported measures of their exercise attitude, subjective norm, perceived behavioral control (PBC), intention, and PEB. We found that attitude, subjective norm, and PBC explained 55% of the variance in intention, and intention and PBC explained 51% of the variance in PEB. While we found sex and exercise group differences across the study measures, we did not find evidence of significant moderation. Thus, the theory constructs predicted intention and PEB similarly across sex and exercise groups. 相似文献

AbstractPurpose: The paper explores the role of boundary work and boundary objects in enhancing learning and innovation processes in hybrid multi-actor networks for sustainable agriculture (LINSA).Design/Methodology/Approach: Boundary work in LINSA is analysed on the basis of six case studies carried out in SOLINSA project under a common methodology. In developing typologies of boundary work and objects, a grounded approach is used.Findings: LINSA analysis demonstrates the dynamic character, diverse forms and multiple functions of boundary work and objects in three domains: learning, innovation, and sustainability. Addressing specific types of goals and actors leads to specific types of boundary work and boundary objects. Context-appropriate boundary work allows aligning differing actor attitudes, gaining increased external support, and developing LINSA. The concepts of boundary work and boundary objects are relevant in a broad range of divergent LINSA settings. Boundary work has its limitations, but its facilitation supports reaching LINSA goals.Practical Implications: The paper proposes recognising context-appropriate forms of boundary work and skilful use of emerging boundary objects to both promote internal consolidation of LINSA and effective external communication to foster learning and innovation for sustainability.Originality/Value: The paper provides insights into the forms, dynamic and outcomes of boundary work in LINSA in three key domains: developing shared knowledge base, co-producing innovation and negotiating sustainability. 相似文献

Conclusions We are living a deep change in the information transfer process involving the different actors of the editorial scene (from
authors to editors, web-editors, e-publishers and readers), who occasionally play different roles at the same time (e.g.,
authors sometimes bypass the editor thus assuming direct responsibilities in the diffusion of documents in the Internet).
Furthermore, information producers, managers or seekers often show twofold personalities like Dr. Jekyll and Mr. Hyde. They
would like to find all documents free on the Internet and be able to read original, reliable, and high quality information,
but they are sometimes reluctant to spread their papers through online nonofficial channels as they care for the impact factor,
prestige, and career advancement.
It is a revolutionary period in which new and alternative forms of scholarly communication live together with more traditional
ones and the future is difficult to define. Recent initiatives of open access—such as Pubmed Central, Public Library of Science,
Budapest Open Access Initiative—are contributing to define new trends in the editorial market, challenging the traditional
distribution channels, mainly managed by commercial editors, and placing the authors’ role and publication copyrights under
severe discussion.
In this landscape, GL now has new dignity and becomes closer and closer to innovative scientific publications supported by
researchers in view of a generalised movement towards open access. The nuances of grey are becoming lighter and lighter. The
questions are many, the answers few, but, in any case, the ethical responsibility of producing and issuing quality documents
can never be disregarded. 相似文献

Recognition of prior learning (RPL) has increasingly been recognised as a useful way to certify experience and competencies gained in the workplace informally. Particularly pertinent is RPL in the context of international migration or in economies, where system reforms seek to overcome challenges related to access to formal training and qualifications. India has the goal to skill 300 million of its growing workforce and provide them access at various levels to certification and further learning opportunities. As a part of the overall system reforms, the Government of India, jointly with the ILO, pilot tested RPL in four sectors in collaboration with the industry and built the foundation for wider replication for another 26 growth sectors by undertaking a tracer study and evaluation. This paper can empirically establish that RPL has had a positive effect on income opportunities, occupational safety, social status and openness to further learning. The paper further discusses the challenges encountered during the implementation of the RPL projects before concluding with recommendations, highlighting the aspects required for quality RPL in an emerging economy. It closes by emphasising the importance of conducting tracer studies to determine impact and the need to provide complementary training during the RPL process. 相似文献
