Covid-19 in Central America: Firm resilience and policy responses on employment

This paper examines how government support interacts with firm-level resilience capabilities in the reduction of layoffs among formal firms in Central America. Our analysis suggests that government support measures play a role in reducing the probability of layoffs among firms with only dynamic resilience capabilities (i.e., those that are developed after the pandemic onset). The effect of government support is not statistically different from the effect of static resilience capabilities alone (i.e., those that were present before the pandemic); thus, in firms with such capabilities, the effect of government support will be marginal. These results hold across sectors - exhibiting a marginally higher treatment effect in service sectors. Our results do not imply that Covid-19 supportive measures are to be disregarded, but instead raise the question of how government support policies could improve the allocation of support among firms in times of crises. Moreover, it underlines the necessity of policies that enhance resilience more broadly – a task that hints at structural issues and requires continuous government support in lieu of ad-hoc measures.     

Probabilistic frontier regression models for binary type output data

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.     

"指标困局":农村贫困治理的实践与反思

在国家的扶贫实践中，地方政府的行为策略是影响扶贫绩效的关键变量。通过对精准扶贫政策实践的调研发现，中央政府不断升级的治理手段为重构央地关系创造了条件，地方政府对国家扶贫理念转型认知的偏差以及在形成路径依赖之后的策略行为不仅容易产生对总体局势的误判，还为后期的政策困局埋下了伏笔。在此背景下，地方扶贫工作遭遇“指标困局”，即地方政府很难实事求是去识别贫困户，只能在既有的指标约束下进行精准识别，扶贫工作陷入了反复识别，却仍难实现精准的怪圈。     

组织支持、城市融入与新生代农民工离职:一个被调节的中介模型

新生代农民工过于频繁的离职行为导致企业用工成本上升,同时也阻碍了农民工的城市融入进程.基于组织支持和互惠理论,采用问卷调查的方式,实证检验了组织支持感、城市融入感及互惠与新生代农民工离职意愿之间的关系与作用机制.研究结果表明,组织支持感负向影响新生代农民工的离职意愿,城市融入感在其中起到了中介作用.同时,新生代农民工的互惠倾向对城市融入感与离职意愿的关系具有强化调节作用,并进一步调节城市融入感在组织支持感与离职意愿之间的中介作用,也即新生代农民工的互惠水平越高,城市融入感的中介作用越强.文章首次测度了新生代农民工的互惠倾向,并且验证了微观企业的组织支持能够促进新生代农民工的城市融入.研究结论为用工企业更好地理解新生代农民工心理行为机制,从而建立有效的管理措施提供了理论指导,同时为寻找新生代农民工城市融入的实现路径提供了依据.     

半参数空间ZISF的估计、分类与蒙特卡罗模拟

零无效率随机前沿模型（ZISF）包含随机前沿模型和回归模型，两模型各有一定的发生概率，适用于技术无效生产单元和技术有效生产单元同时存在的情形。本文在ZISF的生产函数中引入空间效应和非参函数，并假设回归模型的发生概率为非参函数，构建了半参数空间ZISF。该模型可有效避免忽略空间效应导致的有偏且不一致估计量，也避免了线性模型的拟合不足。本文对非参函数采用B样条逼近，使用极大似然方法和JLMS法分别估计参数和技术效率。蒙特卡罗结果表明：①本文方法的估计精度和分类精度均较高。随着样本容量的增大，精度增加。②忽略空间效应或者非参数效应，估计精度和分类精度降低，文中模型有存在必要性。③忽略发生概率的非参数效应会严重降低估计和分类精度，远大于忽略生产函数的非参数效应的影响。     

政治关联如何影响社会组织有效性？——组织自主性的中介作用和制度支持的调节作用

社会组织领域的政治关联现象日益显著，但政治关联究竟如何影响社会组织有效性，其隐藏的作用机制又是什么？这是学术界尚未明晰的重要课题。针对254家社会组织的问卷调查发现，社会组织政治关联会正向影响组织有效性，这一关系受到组织自主性的中介作用影响。更进一步的研究显示，制度支持能调节上述中介关系。具体而言，当制度支持水平较高时，这一效应将会增强；当制度支持水平较低时，政治关联通过组织自主性间接影响组织有效性的效应就会减弱。这一发现，一方面增进了我们对社会组织政治关联的理解，另一方面也为提升社会组织有效性的理论和实践提供了重要启示。     

Peer support and food security in deaf college students

Abstract

Objective: The purpose of the study was to investigate whether peer support and demographic characteristics predicted food security among deaf college students. Participants: The sample included 166 deaf college students at Gallaudet University. Methods: Participants completed a bilingual online survey in American Sign Language (ASL) and English. This survey included USDA’s 6-item food security survey, questions about peer support and socio-demographic characteristics. Results: Out of 166 students (mean age =23; SD?=?6), 60.7% were food secure. About 26.4% were at-risk for low food security and another 12.9% had very low food security. The sample included respondents who identified as people of color (54%) and women (52%). Binary logistic regression revealed that compared to people who reported always receiving peer support, people who never received peer support were 16.3 times more likely to experience food insecurity (adj OR: 16.325, 95% CI 1.824–146.107). Conclusions: This study demonstrates a strong relationship between peer support and deaf college students' food security experiences.     

Coping with Vulnerabilities in Old Age and Retirement: Cross-border Mobility,Family Relations and Social Networks of German Retirees in Alanya

ABSTRACT

Reduced income upon retirement is a vulnerability threat, which increases dependency on public provisions, familial, and/or social (community) support. Many German retirees, in addition to lifestyle motivations, move to low-cost destinations in order to maintain an autonomous and independent life while minimizing the risks of financial worsening. In this article, I discuss the vulnerability patterns of German retirees in the Mediterranean coastal town of Alanya, Turkey, and the role of social networks, with a particular focus on intergenerational family relations. I argue that, despite increased life satisfaction, relocation to a new destination abroad results in new emerging threats. German retirees in Alanya experience difficulties in terms of a lack of intergenerational family support and the double jeopardy of being framed by the legal regulations of two nation states. Based on the findings of the empirical research conducted in Alanya in 2017, I will demonstrate new threats emerged after relocation and how retirees respond to those with new coping strategies.     

Examining risk and protective factors on progression of romantic relational aggression among young adults: Parental control,parental care,and peer social support

Abstract

Romantic relational aggression is related to numerous mental health consequences but risk and protective factors of perpetrating this type of aggression, historically, have been unclear. This study fills in the research gap by evaluating the impact of parental control, parental care, and peer social support on later perpetration in romantic relational aggression among 84 predominately Chinese college students. Results revealed the positive association between parental control and perpetration in romantic relational aggression, however, this association diminished in the presence of high peer social support (HSS). Despite insignificance in the main effect, parental care was negatively correlated with later perpetration in romantic relationship in the HSS group while a positive association was found in the low peer social support (LSS) group. These highlights provided evidences how parental control and parental care during childhood could be risk factors for later romantic relational aggression as well as how current social support from peer could serve as a protective factor on the negative influence from parent–child relationships.
