Recent discussion of the Community of Practice (CofP) ( Davies 2005 ) has suggested that there are certain limitations to the approach with regard to how it accounts for internal hierarchy and community membership. Eckert and Wenger (2005: 588) have suggested that the only way to evaluate such criticism (and avoid building an inappropriately rigid conception of power into CofP theory) is to explore how hierarchies operate within CofPs. This paper offers such an exploration. Using data from a long‐term ethnographic study of a high school in the north‐west of England, this paper will use narrative analysis (drawing upon the work of Labov and Waletsky [1967] 1997 amongst others) to explore the interactional space in which speakers actively negotiate their personal and community behaviour. The analysis focuses upon the role individuals play as narrators of community practice and illustrates that status inequalities between individual CofP members do not necessarily result in inequitable allocation of control within the CofP. 相似文献

This paper pools cross-section data to obtain an estimate of the overall effects of unions on relative wages for the period
1967 through 1977. We found the average union wage premium for all workers to be roughly 24 percent, but that this premium
varies substantially between subgroups of workers. Our analysis showed that real wage rates increased faster in the union
sector than in the nonunion sector between 1967 through 1977. However, we found that this relative growth pattern in wages
was caused by economic conditions rather than in any fundamental shift in the power of unions.

The study of statistical inference for stochastic processes has evolved along two paths. Some problems related to particular processes have been studied, and also some trials to extend general results obtained for independent identically distributed random variables have been made. We retrace the first main contributions, evaluate their influence, and give an idea of the evolution of the research in the field of statistical inference made with observations coming from a stochastic process. 相似文献

Results of this study indicate that pen and paper questionnaire procedures can be successfully adapted to random digit dialing telephone interview methods. Further, the study produced a reliable instrument for measuring attitudes about how residents perceive their communities as a place to live. 相似文献

In this study, the authors evaluated the feasibility and efficacy of a binge drinking prevention intervention for college students delivered via the Internet versus a parallel print-based intervention delivered via postal mail. A total of 116 college students completed the baseline survey. The authors then randomized the students into the Web or print group and sent them intervention materials. One hundred and six students completed the posttest survey. The intervention consisted of a series of 4 weekly "newsletters" in electronic or print format. The authors collected data using a standardized online 42-item survey. They found that an Internet-based binge drinking prevention intervention for college students was feasible. Results supported the efficacy of this intervention for those students already binge drinking, regardless of delivery mode. The authors found no significant differences on outcome measures when delivered via the Internet or postal mail. Results lend support to the use of the Internet as a viable alternative to more traditional health intervention delivery methods. 相似文献

Mutations in the DJ-1 gene are associated with rare forms of autosomal recessive early-onset Parkinson's disease (PD). Although the precise physiological function of DJ-1 remains obscure, accumulating evidence suggests that DJ-1 may normally function as a redox-sensitive molecular chaperone that can protect against the deleterious effects of oxidative stress, particularly in mitochondria. Recent studies in the fruit fly, Drosophila melanogaster, have shed further light on the biological role of DJ-1. DJ-1-deficient Drosophila models exhibit distinct phenotypes but collectively highlight a prominent neuroprotective role for DJ-1 against oxidative insult. However, Drosophila lacking DJ-1 do not consistently produce a useful PD-like phenotype (that is, they generally fail to exhibit degeneration of neurons that contain the neurotransmitter dopamine), which may reflect putative compensatory neuroprotective mechanisms. DJ-1-deficient fly models further highlight the utility of Drosophila as an important tool for elucidating protein function and for modeling neurodegenerative disease. 相似文献

Many Australians are requiring mental health care, including families, leading to long wait times in order to access support. Walk-in therapy reduces barriers to mental health support services by providing support at the time that families seek help. This paper presents a proof-of-concept study investigating the acceptability and short-term effectiveness of an online walk-in family therapy service, Walk-in Together (WIT). Part 1 of the paper describes the experiences of 44 family members from 22 families who presented to a public family therapy clinic for a virtual walk-in family therapy session. The session was conducted by a team of three experienced family therapists. Family members' experiences were sought pre-session, post-session, and at 6 weeks follow-up via survey and interview. Part 2 of the paper explores therapist perceptions (n = 7) of the WIT approach, through thematic analysis of semi-structured interview data. Post-session feedback showed 85% of family members found WIT to be helpful and 50% were optimistic about their future as a family after their WIT session. Six weeks post-session it was revealed that WIT supported planning for families in equipping them to move forward with 88% of family members reporting that they knew what to do after the session. All therapists uniformly experienced the model as offering a timely and beneficial service, suitable for diverse presentations and constellations of families. These preliminary results suggest the significant utility of this WIT intervention as a well-received and helpful service for families, who valued the easy access and rapid therapeutic response afforded by the online, walk-in delivery model. This proof-of-concept paper suggests the potential for further development and growth of WIT, as well as other mental health support services using a walk-in, telehealth model to meet the rising demand for therapeutic support for families in distress. 相似文献
