Macro-Economic Factors in Credit Risk Calculations: Including Time-Varying Covariates in Mixture Cure Models

The prediction of the time of default in a credit risk setting via survival analysis needs to take a high censoring rate into account. This rate is because default does not occur for the majority of debtors. Mixture cure models allow the part of the loan population that is unsusceptible to default to be modeled, distinct from time of default for the susceptible population. In this article, we extend the mixture cure model to include time-varying covariates. We illustrate the method via simulations and by incorporating macro-economic factors as predictors for an actual bank dataset.     

Analysing facilitating and hindering factors for implementing gender equality interventions in R&I: Structures and processes

This article analyses the facilitating and hindering factors that have affected the implementation of gender equality interventions in research and innovation in Europe. It applies the evaluation framework developed in the EFFORTI project that recognizes the complexity of evaluating gender equality interventions in R&I, the importance of factoring in context to any sound evaluation as well as the need to distinguish between the design and implementation of interventions in evaluations. It is based on the analysis of 19 empirical case studies carried out throughout Europe and focuses on those structural and procedural factors that have either facilitated or hindered the implementation process of these interventions. Findings include how the governance framework; top-management commitment; bottom-up participation; framing synergies with other initiatives, strategies for tackling resistance; resources; sustainability of actions; gender competence, experience and knowledge and transparency, targets, standards and monitoring; and accessible data and information all contributed to the successful implementation of the interventions.     

Risk factors for child maltreatment in South Korea: An investigation of a nationally representative sample

This study investigated the risk factors associated with the occurrence of child physical and psychological abuse in South Korea based on the ecological theory of child maltreatment. A subsample of 3‐ to 18‐year‐old children from “A Study on the Current State of Child Abuse and Neglect,” a nationally representative study on child abuse and neglect, was utilized for secondary data analysis. The sample was divided into two age groups (third graders in elementary school and below and fourth graders and above). We utilized hierarchical logistic regression for each age group separately to analyze the data. The variables at each level of the system (i.e., ontogenic development, microsystem, and exosystem) were entered into the model in sequential order. The results showed the common risk factors for both age groups are the caregiver's experience of abuse in childhood, the child's problem behavior, exposure to domestic violence, community size, and informal social control. The child's age was also significant in both groups but in the opposite direction. Social support was a significant predictor for the younger age group only, while the caregiver's level of education was significant for the older age group only. Implications for future research and practice are discussed based on the study results.     

建立以本土企业为主体的协同创新机制研究

改革开放以来,我国经济发展取得了巨大成就,但也面临一些重大挑战,特别是本土企业加入、依赖跨国公司主导的产业链,在短期内得以迅速发展的同时,也导致本土产业链出现了断裂和碎片化的问题,这对本土企业的创新和发展是不利的。文章研究在我国建立以本土企业为主体的协同创新机制的基本规律和特点,为提高本土企业的创新能力提供借鉴。研究的主要发现是,这是一个复杂和曲折的过程,在这一过程的启动阶段和转折阶段,非经济因素或者至少是长期经济因素而不是短期经济因素具有独特的、非常重要的作用。     

论影响科技成果转化的非技术因素

科技已成为推进社会、经济发展的果转化中最为根本的影响因素.但随着经济、社会的发展,其他要素如风险投资、管理、知识产权、资金等对科技成果转化都会产生不同程度的影响.文章主要分析影响科技成果转化的非技术因素.     

究竟是按所有权分配还是按贡献分配?--与《关于深入研究社会主义劳动和劳动价值论的几个问题》一文商榷

价值分配的对象是价值,不是财富.按劳分配的现实理论依据是劳动价值论,最终理论依据是按贡献分配.按生产要素分配的理论依据是以承认其价值创造作用为基础的按贡献分配,而不是按所有权分配.     

IT投资转化为企业生产率的影响因素研究

关于"IT投资是否能提高企业生产率"这一命题,学界一直众说纷纭,一个很重要的原因在于这些研究建立在IT投资能对企业生产率产生直接影响的假设前提之上,而忽略了IT作用于企业生产率的中间过程。IT投资必须与企业内部生产环境相吻合才能提高企业生产率,IT投资转化为企业生产率的影响因素包括内部因素和外部因素,其中内部因素包括企业管理特征、企业员工特征及企业结构特征;外部因素指的是企业所面临的外部环境。     

城市化进程中失地农民就业保障的政策选择

解决失地农民的就业问题是我国现阶段新农村建设中的一个重要内容。近年来失地农民的就业基本情况有转移就业压力大,无就业和隐性失业等工作不稳定的状态,因土地征用而产生收入下降、生活得不到保障、助长社会不良现象的问题。影响失地农民实现就业的因素有土地征用制度、再就业安置措施、失地农民自身素质、就业歧视。今后必须重视失地农民的就业问题,完善土地征用补偿机制和就业安置方式,完善法律保障和社会保障体系,加强就业培训,转变就业观念等方面完善失地农民就业保障的政策。     

Placement characteristics and stability: a longitudinal analysis of Norwegian children in foster homes

This paper investigates how enhanced support for foster parents, such as covering fees and providing consultants and relief, may reduce the number of replacements experienced by children in foster care. It also investigates the extent to which replacements are associated with family (kin) vs. non‐family foster parents, or with legal characteristics of the placement (i.e. forced administrative decisions vs. relief measures agreed upon by the parents). Statistical analyses of administrative data from Norway investigated the longitudinal relationships between these characteristics and the number of replacements at two levels – children (N = 16 109) and municipalities (N = 418) – over 5 years (2007–2011). The results reveal modest associations between enhanced support and fewer replacements; for example, replacement rates are lower for children placed in homes of kin than in non‐family homes. Replacements also tend to be fewer when the placement is forced rather than consensual.     

战略性新兴产业创新能力影响因素研究综述

从战略性新兴产业的特征入手, 对战略性新兴产业创新能力影响因素的相关文献进行综述。战略性新兴产业创新能力的影响因素主要包括知识产权能力、产业集群、金融支持、政府补助、产业政策与技术创新六大方面,现有文献主要围绕这六个方面进行相关研究。现有研究主要采用假设检验、实证分析、构建模型等研究方法与评估体系,而比较研究是战略性新兴产业创新能力研究中的重要内容。学界对战略性新兴产业的研究数量较多,但大多数只是宏观地探讨战略性新兴产业的发展及某些影响因素。由于战略性新兴产业包含不同行业,各个产业的特性存在差异,对于具体某一个战略性新兴产业的发展还需要进行更广泛更深入的研究;同时,技术、政策以及融资环境等某一因素对战略性新兴产业的影响研究慢慢增多,但是对不同因素带来的交叉影响研究还有待深入。
