针对目前起重机安全评价过于依赖主观权重且忽视起重机安全状态变化趋势的问题,建立基于改进博弈论组合赋权法(improved combination weighting method of game theory,ICWGT)和灰色关联分析法的起重机安全评价体系。在该评价体系中,收集样本数据以确定评价值,构建评价等级空间来计算起重机行为特征序列与标准行为特征序列的关联系数。运用ICWGT在层次分析法和信息熵 未确知测度理论确定的主、客观权重中寻找平衡。充分考虑专家经验和样本数据,确定优化权重以改善关联系数的分配问题,从而获取起重机灰色关联度评价值和安全等级,旨在对起重机安全状态变化趋势进行更加准确的定量描述和定性分析。实例分析验证了该评价体系的有效性。 相似文献

文章在建立数字资源配置多目标协同评价指标体系的基础上,构建了基于灰色关联投影法的资源配置多目标动态评价及障碍因子诊断模型,并以昆明理工大学图书馆2012—2020年数字资源配置的动态变化对模型进行了实证分析。实证表明:研究对象的多目标协同评价水平在研究期内缓慢提升,子目标之间的协调性逐渐增强,重心由内容评价逐渐转向使用评价;内容评价在整个研究区间内处于快速上升状态,系统评价是先快后慢地上升,使用评价是先慢后快地上升,成本与服务评价则一直处于缓慢上升状态;影响资源配置多目标动态评价的障碍因子类别、数目及障碍度都处于动态变化中,历年障碍因子总体上由内容与系统评价向使用与成本评价类因子转变。 相似文献

This study surveys transitions specific to parents of children with autism spectrum disorder (ASD), examines how aspects of relational turbulence vary based on the type of transition experienced, and explores the transition processing activities couples use to navigate marital transitions in this context. The study examined the transition experiences of 298 parents of children with ASD who were currently married. Participants detailed an important transition throughout the life span of their child with ASD using open-ended questions. They completed scales assessing qualities of the relationship during the transition and transition processing communication used to navigate the experience. Results demonstrate significant differences in experiences of relational turbulence based on the type of transition described. In particular, the initial diagnosis received the highest ratings for transition magnitude and relational turbulence compared to other common transitions. Engagement in transition processing communication predicted relational uncertainty and facilitation from a partner, which predicted relational turbulence. 相似文献

The transition from deployment to reintegration can be stressful for returning military personnel and at-home partners, and support plays a key role in their ability to transition effectively. We draw on relational turbulence theory to advance predictions about how parameters of the relationship between returning service members and at-home partners predict their perceptions of their partner’s support during the post-deployment transition. We surveyed 235 individuals (117 returning service members, 118 at-home partners) who had experienced the transition within the past 6 months. Findings consistent with the theory indicated that relational turbulence partially mediated the negative associations that relational uncertainty and interference from a partner shared with partner support. Partner uncertainty was a direct negative predictor of partner support as well. We consider how these results extend theory, research, and practice. 相似文献

Relational transgressions are emotionally difficult for those who directly experience the transgression. Less is known about how transgressions affect those located within the personal network of a relational transgression victim. This study explored how network members engaged in support marshaling in response to another’s transgression experience. Results indicate that some participants marshaled support, citing four reasons for their actions: perceived insufficiency, camaraderie, personal ramifications, and personal values. We explore these reasons for marshaling support and discuss them within the broader context of support marshaling and relational transgressions. 相似文献

This article proposes that restorative justice practices (RJPs), as used in New Zealand schools, are better understood as an instrument of social development than a behaviour management practice. Concerns about the achievement of Māori students are relocated, from an individualised psychological and pedagogical problem to an interdisciplinary context of historical and social development. Social constructionist theory is suggested as a lens through which RJPs in schools may be seen as the intentional production of respectful social relationships, rather than as behaviour management. A restorative process has the productive capacity to restore healthy relational functioning, both for those who have been offended against and those who have offended. It is argued that the primary function of restorative justice in schools is not about resolving specific conflicts, but rather, about the production and maintenance of respectful relationship, which is the antithesis of colonised relationship. Such a position reflects accountability on a communal, rather than individualised basis, and accords with recent moves in the United Nations Development Programme to look at Human Development as building agentive capacity. 相似文献

一词多义是各种语言中普遍存在的现象。英语中除了术语以外,单义词是很少的,多数的词都是多义词。本文从认知语义学的视角,运用认知语言学的"原型范畴理论"以及"基于理论的多义词分析法"对动词make进行认知研究,探索构建make一词多义的意义关系模式。 相似文献

摘要:主要采用文献资料法,以社会嵌入理论为视角,探析“社区—社会体育组织—社会体育指导员”联动运行机制及其实施过程中急需解决的核心问题和实施策略。研究提出:社区体育组织形式有效地吻合了全人群和全生命周期为立足点的全民健身要求;“社区—社会体育组织—社会体育指导员”联动运行必须以“社区嵌入社会”和“社会体育指导员嵌入社会”为理念,以社会体育组织为核心开展工作;联动运行不仅限于基层社区内部,而且还要通过以社会体育组织为核心纽带实现基层社区体育横向网络和国家、省、市级纵向网络交互联系的社区体育网络体系;联动运行的实践是政府规划体育公共服务项目并实施监管,社会体育组织实施项目,社会体育指导员全职融入社会体育组织提供人力资源保障;联动运行的关键是实现社会体育组织实体化和社会体育指导员职业化;联动的实施策略是通过在全社会实施认知性嵌入、文化性嵌入、政治性嵌入、结构性嵌入,构建与联动相适应的社会环境。为今后社区体育的组织与管理提供理论借鉴。 相似文献

Persistent school shootings have generated ongoing pressure to assess and enhance crisis communication effectiveness via strategies such as resilience-building and post-crisis restoration. A network perspective offers a robust, multilevel approach for examining complex information flows among community, campus, and individual actors affected by crises. Drawing on relational and structural embeddedness and Uncertainty Management Theory, we offer nine propositions that help explain structural and relational changes in a network over time. Although theoretically driven, these propositions are primarily functional, offering practical implications for safety officials and administrators trying to understand, prepare for, and respond to crises. Thus, we suggest measures and recommendations to improve information flow, uncertainty management, and resilience before, during, and after a crisis. 相似文献
