Knowing is an enacted, communicated process that is difficult to observe, let alone manage, in organizations. Communities of practice (CoPs) offer a productive solution for improving knowledge and knowledge management, but the communicative processes that enact CoPs have not been explored, leaving CoPs as an organizational black box. This research extends CoP theory as a means to determine the presence of a CoP and distinguish between various CoPs, and as a practical means to evaluate the communicative processes of organizational knowledge. CoPs enact the communicative nature of knowing through the elements of mutual engagement, negotiation of a joint enterprise, and shared repertoire. Specifically, two groups of volunteers are examined through a combination of participation, observation, and interviews in order to explore CoP theory as a dynamic system for examining and evaluating organizational knowledge. 相似文献

This study examines our experiences as female junior scholars with multicultural backgrounds teaching at the same Hispanic‐serving institution. As education scholars with mixed‐heritage families, we identify with the commitment to serving Latinos and the number of mixed‐heritage people in the USA. The election of Barack Obama, whose racial background is both black and white, to the US presidency signifies the emergence of mixed‐heritage people as a demographic presence in this country. Our research suggests that more understanding is needed about the experiences of mixed‐heritage faculty in academia, as well as the ways in which faculty from any background may develop multiple affiliations with cultural communities and pursue professional agendas related to communities that they do not neatly fit into. Despite this variation in backgrounds and research agendas, we share our efforts in advancing Latin@ educational attainment. 相似文献

Developing a communal identity as beginning teachers of mathematics: Emergence of an online community of practice 总被引:1,自引:0,他引:1
The aim of this study is to investigate how a community of practice focused on becoming a teacher of secondary school mathematics
emerged during a pre-service teacher education programme and was sustained after students graduated and began their first
year of full-time teaching in schools. Bulletin board discussions of one pre-service cohort are analysed in terms of Wenger’s
(1998) three defining features of a community of practice: mutual engagement of participants, negotiation of a joint enterprise,
and development of a shared repertoire for creating meaning. Emergence of the online community was associated with our own
role in facilitating professional dialogue, the voluntary and unstructured nature of participation, initial face-to-face interaction
that created familiarity and trust, and the convenience of using email rather than logging on to a website. The study shows
that the emergent design of the community contributed to its sustainability in allowing the pre-service and beginning teachers
to define their own professional goals and values.

A 64-year-old security guard and longstanding known hypertensive presented with hypertensive heart disease (HHD), weight loss,
an enlarged prostate, and a spontaneously fractured rib. Malignancy of the prostate with possible metastases to the ribs was
strongly suspected. Biochemical profiling revealed a paraprotein. Other biochemical and hematological correlates that were
on hand before serum protein electrophoresis were rather atypical. Paraprotein studies by immunofixation revealed IgA myelomatosis.
Unlike previous reports from Caucasians there was normocalcaemia, normal protein level, microcytic hypochromia, low MCHC,
cholesterol level at the lower limit of the reference range and normal urea level (in the face of markedly raised creatinine
level). Nutritional modulation of the classical laboratory features of this disease may account for the fairly atypical laboratory
picture.
The need to appreciate the influence of nutritional status on the laboratory (especially biochemical) features of a disease
and thus interpretation of diagnostic tests appears of exceptional current importance, given the widening gap in socioeconomic
status and the level of poverty between the resource poor and developed countries from which the classical, clinical and laboratory
features of most diseases were first described.
This case report reminds of the need not only to recognize theoretically the impact of nutritional status on the laboratory
characteristics of a disease but of the practical application of the nutritional perspective in the interpretation of diagnostic
investigations, especially in nutritionally disadvantaged communities. 相似文献

改革开放给贵州村社带来了深刻的变革。当人们目睹贵州村社物质结构深刻变革的同时,也要思索物质结构变革如何作用于精神结构,以及精神结构如何变迁。从古老到现代性的变迁是贵州村社精神结构变迁的总体路径;从形式到内容的变迁是贵州村社精神结构变迁的本质;从旧生代到新生代的变迁是贵州村社精神结构代际分裂式的变迁。 相似文献

Numerous national reports have identified the importance of significantly improving pathways that begin with Latinx students enrolling in 2-year institutions and ultimately completing baccalaureate degrees in STEM fields at 4-year institutions. Many programs using multiple interventions have been designed, implemented, and studied to achieve this goal. To synthesize what has been learned from studies of these programs, this article presents a systematic review of published studies of programs designed to support Latinx student success in 2-year institutions and successful transfer to 4-year institutions, particularly for STEM majors. A total of 49 quantitative, 9 qualitative, and 16 mixed-methods studies published as reports, articles, or dissertations since 1980 were identified that met the criteria for the review. Studies covered a wide range of interventions, including mentoring, counseling, advising, study groups, tutoring, scholarships, orientations, career services, undergraduate research, articulation agreements, and transfer programs. Individually, these studies report positive influences on student success outcomes, including 2- and 4-year graduation, transfer to a 4-year institution, retention, and success in individual courses. However, the number of qualifying studies was surprisingly small, considering the importance of improving success of Latinx students and the length of time during which the problem has been repeatedly emphasized. Few interventions have been undertaken from explicitly assets-based perspectives or theoretical frameworks. The lack of explicit frameworks underlying interventions—combined with a sole/primary focus on students—suggests many interventions were approached from a deficit-based perspective. Further, the study found no pattern of replication studies that might confirm effectiveness of potentially promising interventions. Based on our analysis of evaluations presented in the studies, it does not appear that the research community has developed agreed-upon methods to evaluate commonly agreed-upon outcomes. Finally, no intervention has been sufficiently supported that widespread implementation could be recommended. 相似文献

This study sought to investigate the association between nativity status and Hispanic young women’s formal sex education and parental sex education in the USA. We used data from a cross-sectional sample of 310 Hispanic young women aged 18–24 years old from the 2013–2015 US National Survey of Family Growth. We assessed 11 outcomes: four formal sex education topics; receiving any formal sex education; a formal sex education scale; four parental sex education topics; and receiving any parental sex education. The majority of our sample was US-born Hispanic versus foreign born (72.6% and 27.4% respectively). Foreign-born Hispanics were less likely to have received any type of formal sex education than US-born Hispanics (adjusted odds ratio = 0.81; 95% confidence interval: 0.24, 0.68, p < 0.01). Foreign-born Hispanics were less likely to have received parental HIV sex education than U.S.-born Hispanics (aOR = 0.36; 95% CI: 0.14, 0.97, p < 0.05). Nativity status did not have a significant effect on each unit increase on the scale (aB = –0.07, SE = 0.16; aβ = –0.42, p > 0.05). Our results indicate that having appropriate sex education knowledge is better than not being cognisant. Future studies should however examine the quality and content of sex education programmes so policymakers can better understand these young women’s sexual behaviours and decisions. 相似文献

While long-acting reversible contraception (LARC) reduces risk of repeat-births, use remains low among rural Latinx adolescent mothers. This qualitative study identified perspectives about factors that influence LARC use among this population. Participants were dyads of parenting Latinx adolescent daughters and their mothers (n?=?9 dyads) and nurses (n?=?17). Findings revealed themes specific to this vulnerable population including (a) distinct ways LARC characteristics fit into parenting teenagers’ lives, (b) supportive health care climate toward LARCs, and (c) factors that inhibit LARC uptake. The study has implications for sexuality education that seeks to reduce repeat-births among this population. 相似文献
