试析未成年犯罪记录封存制度必要性     

束传祥 《齐齐哈尔师范高等专科学校学报》2014,(2):83-84

未成年犯罪记录封存制度作为刑事诉讼法新设的一项制度,是未成年刑事诉讼程序的重要组成部分。制度之必要性建构在考量未成年犯罪案件特殊性及保护未成年罪犯隐私权基础上。其功能性价值在于保护未成年罪犯免遭社会非规范性评价并促进未成年犯罪者有效融入社会,预防其再犯,降低社会风险。  相似文献

Distributed leadership with the aim of ‘reculturing’: a departmental case study     

Wayne Melville  Doug Jones  Todd Campbell 《School Leadership & Management》2014,34(3):237-254

This article considers a secondary science department that has, since 2000, developed distributed leadership as a form of human capacity building. Using a longitudinal ethnographic case study allowed us to consider how distributed leadership can be nurtured and developed in a department. Our analysis centres on two key issues: the nature and pattern of distributed leadership practices and the continuity that provides coherence to those practices. From our analysis, there appear to be two major conclusions. The first of these is the need for administrators to be purposeful in the appointments that they make to formal leadership positions. To enact distributed leadership practices requires leaders who can exercise both formal power and influence. The second conclusion relates to the time required for continuity of leadership practices to give rise to changes that lead to teachers managing the teaching and learning programme.  相似文献   

Interrogating conceptions of leadership: school principals,policy and paradox     

Karen E. Starr 《School Leadership & Management》2014,34(3):224-236

Currently educational research literature demonstrates wide discussion and endorsement of ‘distributed’ leadership while concurrently traditional, hegemonic forms prevail in practice. This article investigates understandings about educational leadership held by Australian school principals. The article describes the contradictory conceptions about educational leadership currently in circulation. It interrogates underlying assumptions and questions how both hegemonic and newer leadership conceptions and assumptions serve educational leaders. Data from principals around the country and across education systems reinforced the predominance of un-theorised or under-theorised notions about leadership, with similar assumptions found in important policy artefacts and practices. This article emerges from interviews with 100 principals focusing on their professional learning needs, which revealed interesting ideas, issues and dilemmas concerning ‘leadership’. It fills a gap in research on distributed leadership by exploring contradictions inherent in policy, practice and understandings in this area. The article is structured into four sections. First, extant literature on this topic and the research are explained. Second, the article focuses on principals' conceptions about leadership and those inherent within important policy and practical artefacts. A discussion of the findings focuses on the discrepancy between theory and policy endorsement and the views of practitioners. Finally, the article canvasses the implications of the research.  相似文献   

基于信息传播算法的云存储系统架构研究     

王鸿磊  张雪松 《河北软件职业技术学院学报》2014,(4):38-42

云存储是一种在线网络存储模式,可以为用户提供能直接访问的大范围资源和应用程序。虽然许多云存储提供商已经采用加密策略来保护客户的数据,但是用户还是怀疑数据的安全性和隐私性。通过信息传播算法分析,证明它能够解决云存储数据的私密性、完整性等问题,在此基础上,提出一种采用信息传播算法的云存储系统架构,实验证明,它可以提高云存储数据的安全性、完整性和可用性。  相似文献
