Boundary-Work in the Health Research Field: Biomedical and Clinician Scientists’ Perceptions of Social Science Research

Funding agencies in Canada are attempting to break down the organizational boundaries between disciplines to promote interdisciplinary research and foster the integration of the social sciences into the health research field. This paper explores the extent to which biomedical and clinician scientists’ perceptions of social science research operate as a cultural boundary to the inclusion of social scientists into this field. Results indicated that cultural boundaries may impede social scientists’ entry into the health research field through three modalities: (1) biomedical and clinician scientists’ unfavourable and ambivalent posture towards social science research; (2) their opposition to a resource increase for the social sciences; and (3) clinician scientists procedural assessment criteria for social science. The paper also discusses the merits and limitations of Tom Gieryn’s concept of boundary-work for studying social dynamics within the field of science.

开流格点的时空不可约周期结构

指出了在开流格点中，存在着时间空间不可约周期结构。并通过对初始稳定性和边界稳定性的分析，证明了该结构的稳定性。其数值结果表明了理论分析的正确性。

淮河流域污染的“行政边界效应”与新环境政策影响

本文基于淮河流域2004-2013年国控重点监测断面周数据,运用OLS法和最邻近匹配方法( NNM, Nearest Neighbor Matching)考察地级市行政边界对河流污染的影响。研究表明,淮河流域行政边界下游比上游污染更为严重,“行政边界效应”分别达到-13．764%( DO,溶解氧)、46．453%( COD,化学需氧量)和145．736%( NH3-N,氨氮)。使用双重差分法检验了“十一五”和“十二五”环境政策对淮河流域跨界污染问题的影响,发现纳入考核范围的COD的“行政边界效应”在“十一五”后期才有所改善,“十二五”政策则显著缓解了约束性指标COD和NH3-N的“行政边界效应”。研究对于打破淮河流域各地级市“逐底竞争”的考核机制、制定更为合理的考核办法、鼓励地级市间环境合作治理都有重要的现实价值。     

研发网络边界拓展、知识基与创新追赶

研发网络边界拓展已经成为研究热点。本文聚焦于转型经济的后发企业研发网络组织、地理和知识边界拓展对创新能力追赶的影响这一核心研究问题,整合制度理论和知识基础观理论,提出后发企业研发网络的组织边界拓展和创新绩效有着倒U型的关系。其次,后发企业研发网络地理边界拓展和技术创新绩效有着正向影响的关系。再次,后发企业研发网络知识边界拓展和技术创新绩效有着正向影响的关系。最后,企业内部知识基对后发企业研发网络组织边界拓展对创新绩效的影响存在调节作用。基于926家拥有浙江省高新技术研究开发中心的企业为样本两年数据的实证检验支持了本文的假设。     

Schools, ‘ferals’, stigma and boundary work: parents managing education and uncertainty in regional Australia

This paper examines forms of boundary work undertaken by parents in a regional Australian city to negotiate social processes around the school market amidst rising economic insecurity. It outlines structural changes, which have increased economic inequality in Australia and impacted on educational reform, and the specific challenges faced by public schools in regional settings. Drawing on 18 months’ qualitative research in one regional location, it identifies and analyses forms of boundary work undertaken by middle-class families to manage these uncertainties in a field of scarce economic and cultural resources. Theories of class culture, stigma and whiteness are used to show how local social labels such as ‘ferals’ and ‘shiny people’ acted as classed and racialised ways of negotiating this social and economic landscape through the school field. Such practices engendered feelings of security and control and shed light on feelings of class-based resentment and anxiety in regional Australia, specifically a middle-class ‘fear of falling’.

Legitimizing the Wound: Mapping the Military's Diagnostic Discourse of Traumatic Brain Injury

Following reports spanning from the beginning of the OEF (Operation Enduring Freedom) and OIF (Operation Iraqi Freedom) conflicts to the early 2010s, this rhetorical investigation analyzes the U.S. military's diagnostic practices used to identify mild traumatic brain injury (mTBI) in blast-affected troops. Considering the notion of “wound/injury” as a possible boundary object, this paper discusses how the conceptual framing of “invisible” injuries may produce interruptions of distrust that inhibit effective diagnosis.     

变革型领导对团队创造力的影响机制研究:团队反思与团队边界管理的中介作用

团队创造力已成为新经济条件下企业获取竞争优势的根源。尽管已有研究发现变革型领导对团队创造力具有促进作用,但其中的具体作用机制并未得到充分诠释。基于文献研究和实际调研,构建包含变革型领导、团队反思、团队边界管理及团队创造力相关关系的理论模型。通过对30家高新技术企业的128个知识型团队的问卷调查研究,结果表明:变革型领导对团队创造力有积极影响;团队反思、团队边界管理在变革型领导与团队创造力之间具有部分中介作用;团队反思对团队边界管理有正向促进作用。因此,为提高团队创造力,领导不但要塑造自身的变革型领导风格,而且应实施团队边界管理,促进团队反思。     

浅析小学语文阅读教学中的多元有界性

新课改实施以来,多元化解读的阅读教学开始盛行于课堂。阅读教学中应该注重多元解读。但是,在近期的阅读教学过程中却出现误读和过度拓展等一些误区。本文针对当前多元解读的泛滥现象,试图寻求阅读教学中多元解读的界限和走出误区的策略。
