知识组织最新研究与实践进展 总被引:7,自引:2,他引:5
本文评述了知识组织领域的几个前沿问题的研究进展,以一条从“精英”到“草根”的主线来反映知识组织研究领域理论和实践方面的研究与应用现状。书目记录功能需求(FRBR)在书目工作发展史上具有重要意义,对书目工作有着深刻影响。本体作为一种工具广泛地应用在知识组织乃至信息检索领域之中。受控语言与自然语言的融合,网络环境下传统知识组织工具的改造均为这一领域研究的前沿和重点。而随着草根理论的兴起,大众分类法也逐渐进入研究者的视野,在促进用户信息交流和知识共享中起到重要的作用 相似文献

培训需求分析是增强培训针对性、确保按需施训的基本前提。四川省一项有22.56 万中
小学教师参与的调查发现,不同年龄段教师在培训内容、培训专家、培训方式方法等方面有共同的
需求,但也存在差异。总体上看,对专业能力的培训需求随着年龄的增长而下降,对专业理念和专业知识的需求随着年龄的增长而增长。影响不同年龄段教师培训需求的因素,一是教师专业成长的阶段特征,二是教学的实践特征和社会期望。 相似文献

Miscarriages, stillbirths, and infant loss are a constant threat to Nigerian women. Little research has sought to understand the cultural silence and taboo that typifies these issues needs and its impact on the women. Drawing on 35 in-depth interviews with Nigerian women, this study explored the sociocultural understanding of perinatal loss among Nigeria women. A thematic analysis of the women’s narratives indicated that cultural norms and practices contribute to disenfranchised grief, which translates into ridicule and blame for women, identity loss, marital instability, and a feeling of despair. The findings point to a need for more empirical research into the grieving processes of diverse populations. Theoretical and practical implications are discussed. 相似文献

Unanticipated direction to cut after landing may alter the lower extremity landing biomechanics when performing landing motions. These alterations may potentially increase the risk of ACL injury. The purpose of this study was to determine if an unanticipated side-cut affects lower extremity landing biomechanics in females. Eighteen recreational female athletes participated in two blocks of testing: the first block of testing consisted of three acceptable trials of anticipated dominant limb and non-dominant limb 45-degree diagonal cutting after landing, which were performed in a counterbalanced order. The second block of testing consisted of three acceptable trials of unanticipated dominant limb and non-dominant limb diagonal cutting after landing. Data analysis mainly focused on the dominant limb landing biomechanics. Unanticipated side-cut landing, compared (paired t-test, p < 0.05) to the anticipated landings, resulted in less hip abduction and tibial internal rotation angle at initial contact (IC) and a lower maximum ankle inversion angle and a greater maximum knee abduction angle, and knee and hip displacement. Also, greater posterior GRF and a longer time to peak medial GRF were exhibited. These outcomes indicate that athletes may adapt their landing mechanics to land unsafely when encountering an unanticipated event. 相似文献

This study explored the validity of ActiGraph-determined sedentary time (<50 cpm, <100 cpm, <150 cpm, <200 cpm, <250 cpm) compared with the activPAL in a free-living sample of bus drivers. Twenty-eight participants were recruited between November 2013 and February 2014. Participants wore an activPAL3 and ActiGraph GT3X+ concurrently for 7 days and completed a daily diary. Time spent sedentary during waking hours on workdays, non-workdays, during working-hours, and non-working hours were compared between instruments. During working hours, all ActiGraph cut-points significantly underestimated sedentary time (p < 0.05), whereas during non-working hours the <50 cpm cut-point demonstrated the closest agreement (ActiGraph sedentary time: 250 ± 75 minutes versus activPAL sedentary time: 236 ± 65 minutes). Receiver operating characteristic analyses revealed that on workdays and non-workdays the ActiGraph cut-points exhibited relatively low sensitivity (all <0.62) and specificity (all <0.49) values. The use of the ActiGraph to measure sedentary time in this understudied, highly sedentary and at risk occupational group is not recommended. 相似文献

This exploratory study was an attempt to understand the coming-out process and lived experiences of gay and lesbian individuals in Islamic Malaysia. Fifteen in-depth interviews were conducted, and data were subjected to qualitative thematic analysis. Three themes which centered on the “coming-out” process were uncovered, and they include: disclosure as self-acceptance, concealment as self and other protection, and sexual identity is not public identity. Even though the specific condition for disclosure and concealment vary from individual to individual, relationship with others and safety appeared to be the two most common reasons for why disclosure and concealment were enacted by the participants. 相似文献

参考国外企业针对员工赞助的案例,以社会认同理论为视角,运用内群体理论和自尊假设分别分析体育赞助对企业员工的影响,认为在体育赞助机制作用下,员工与企业会在身份上出现重叠,企业利用这种身份重叠与员工结成利益共同体;体育赞助在企业管理中起到“管理面具”的作用,把企业的价值观和文化传递给员工,潜在地把企业与员工紧密联系起来。 相似文献

马克思没有提出跨越资本主义“卡夫丁峡谷”的思想吗?——与张明军同志商榷 总被引:1,自引:0,他引:1
孙来斌 《河南师范大学学报(哲学社会科学版)》2000,27(3):9-13
本文不同意张明军《马克思没有提出跨越资本主义“卡夫丁峡谷”的思想》一文的主要观点和结论。根据马克思的本意,“卡夫丁峡谷”既指资本主义制度,也指它必然带来的经济危机和灾难,不能将其割裂开来理解。综观马克思给查苏利奇的复信及其他相关文献.马克思非常明确地提出了俄国农村公社在一定条件下可以跨越资本主义卡夫丁峡谷的思想。资本主义的发展并非一切国家和民族的必经之路,生产力相对落后的国家在特定的历史条件下是可以跨越卡夫丁峡谷的,在此同题上不能重犯考茨基等人“经济决定论”的错误。 相似文献
