非传统安全是我国近20年来重点关注的安全领域。对以中国非传统安全及相关主题为关键词的4 003篇中英文文献进行计量分析发现:从研究机构看,国内致力于非传统安全研究的机构主要有浙江大学、复旦大学、国际关系学院等,但还未形成全国范围内的开放、合作格局;从作者分布看,国内不同学科之间缺乏交互性,不同机构的研究人员之间也缺乏合作,而国外研究者的网络密度相对于国内学者要高;从关键词共现、聚类分析与突现词分析图谱来看,国外研究主要着眼于非传统安全研究的细分领域,中国的非传统安全研究在发展和演变过程中形成了四条演进路径,即高阶政治安全研究(1999—2004年)、低阶政治安全研究(2005—2009年)、软性安全研究(2010—2014年)、安全范式以及安全场域研究(2015年至今)。  相似文献

有关宅基地退出影响因素的研究由于区域选择、模型方法、测量方式或具体研究内容的不同,研究结论存在不同程度的差异。为厘清宅基地退出影响因素及其效应,推动宅基地有序退出,在纳入18篇实证文献、137个效应值、78 934个独立样本进行 Meta 分析的基础上,研究了农户宅基地退出的影响因素及影响因素强度随时间的变化,以及农户宅基地退出的影响因素是否存在异质性及异质性来源。结果表明:农户受教育程度、家庭年收入、非农收入占比、宅基地确权、所在地距县城距离及是否在城镇购房对农户宅基地退出意愿均有显著正向影响;年龄、家庭年收入、宅基地面积及是否在城镇购买住房在影响农户宅基地退出方面存在明显的异质性。宅基地退出影响因素随时间变化作用强度也在变化,且不同区域影响宅基地退出意愿的因素作用程度不同,应当根据地区差异对农村宅基地退出有针对性地进行政策引导。  相似文献

聚焦不同时期辽宁自贸区发展建设的政策,通过LDA大数据模型对自贸区建设的阶段性政策文本进行低维主题集合,能够识别大规模文档集中潜藏的主题信息、主题强度及结构特征。在此基础上,对比中央对辽宁自贸区的发展要求,能够准确发掘地方政策实施的侧重点与发展差距,进而识别自贸区建设发展的不足。研究发现:在主题强度上,主题间相似度较低且强度差距不明显;在主题领域上,政策颁布更侧重于行政审批、监管创新、项目建设等领域,而在投资、贸易、外汇管理、金融服务、科技创新、人才政策等领域较薄弱;在主题结构上,行政审批、绩效考核政策主题针对行政体制机制改革,监管创新、政府信息公开、电子信息化服务主题体现“服务型政府”的政策供给重点。基于此,需加强金融贸易、法治营商环境建设、人才引进、企业扶持等领域的政策供给。LDA主题模型;辽宁自贸区;政策文本;聚类分析  相似文献

A longstanding debate in the strategic decision-making literature has focused on whether top management teams (TMTs) can effectively balance speed and comprehensiveness when making important decisions. In our research, we build on early insights and pivot from considering whether TMTs can engage indecision-making that balances these tensions to focus instead on when certain types of TMTs are able to achieve such balance. We employ a novel configurational analytical approach and a theoretical framework built from role theory to examine the CEO-TMT interface in a new way. In so doing, we are able to identify specific CEO-TMT constellations that support decision-making that is both fast and rigorous. Using a unique primary dataset and an abductive, configurational approach grounded in fuzzy set qualitative comparative analysis (fsQCA), we identify six specific leader-team configurations that each facilitate decision processes characterized by rigorous intra-team debate, meaningful reconciliation of divergent ideas, and fast decision speed (which we describe as strategic decision-making balance). The range of CEO-TMT configurations that emerge from our analyses contribute new theory and findings for the strategic decision-making and interface literatures more broadly, as well as the specific research streams on executive gender, humility, and TMT structure.  相似文献

Desirable system performance in the face of threats has been characterized by various management concepts. Through semistructured interviews with editors of journals in the fields of emergency response and systems management, a literature review, and professional judgment, we identified nine related and often interchangeably used system performance concepts: adaptability, agility, reliability, resilience, resistance, robustness, safety, security, and sustainability. A better understanding of these concepts will allow system planners to pursue management strategies best suited to their unique system dynamics and specific objectives of good performance. We analyze expert responses and review the linguistic definitions and mathematical framing of these concepts to understand their applications. We find a lack of consensus on their usage between interview subjects, but by using the mathematical framing to enrich the linguistic definitions, we formulate comparative visualizations and propose distinct definitions for the nine concepts. We present a conceptual framing to relate the concepts for management purposes.  相似文献

Beta regression is often used to model the relationship between a dependent variable that assumes values on the open interval (0, 1) and a set of predictor variables. An important challenge in beta regression is to find residuals whose distribution is well approximated by the standard normal distribution. Two previous works compared residuals in beta regression, but the authors did not include the quantile residual. Using Monte Carlo simulation techniques, this article studies the behavior of certain residuals in beta regression in several scenarios. Overall, the results suggest that the distribution of the quantile residual is better approximated by the standard normal distribution than that of the other residuals in most scenarios. Three applications illustrate the effectiveness of the quantile residual.  相似文献

近年来,专利引文越来越多地被用于技术路径研究、技术会聚、技术扩散等技术领域间的知识活动研究,但并未有效区分申请人引用和审查员引用,现有技术领域层面对申请人和审查员引用差异的对比研究还停留在较为浅显的统计层面。将技术类别间的差异性引入到申请人引用和审查员引用的对比研究中,在技术类别分布基础上,探究专利技术类别多样性视角下申请人引用和审查员引用的知识来源差异,并对其开展相关性分析。研究结果表明:专利申请人引用涉及的技术类别范围更广,而审查员引用则更集中于本技术类别;对大部分技术类别,申请人引用的技术类别多样性要高于审查员引用,但两者呈现出显著的正相关性。  相似文献

This study draws on survey data from 205 family mediation service users concerning their satisfaction with the outcomes of mediation to address two research questions: (a) how satisfied are service users? and (b) what factors account for users' satisfaction with the outcome of child custody arrangements and the allocation of finances and property? Overall, users' level of satisfaction with outcomes was high. While the mediation process explained a significant variance in satisfaction with the outcomes for child custody and for finances and property, the mediator's perceived professional competence did not predict user satisfaction with the outcomes for either issue. This study contributes to our knowledge on the significance of mediators' process skill, specifically their calm and clear responses to the socioemotional needs of the mediated parties, on the service outcomes for both types of dispute. The implications for mediation training are discussed.  相似文献

This paper proposes a probabilistic frontier regression model for binary type output data in a production process setup. We consider one of the two categories of outputs as ‘selected’ category and the reduction in probability of falling in this category is attributed to the reduction in technical efficiency (TE) of the decision-making unit. An efficiency measure is proposed to determine the deviations of individual units from the probabilistic frontier. Simulation results show that the average estimated TE component is close to its true value. An application of the proposed method to the data related to the Indian public sector banking system is provided where the output variable is the indicator of level of non-performing assets. Individual TE is obtained for each of the banks under consideration. Among the public sector banks, Andhra bank is found to be the most efficient, whereas the United Bank of India is the least.  相似文献
