Dual conditionality in welfare and housing for lone parents in Ireland: Change and continuity?

This article focuses on multiple conditionalities in benefits and housing from the perspective of lone parents in Ireland. The Irish case echoes historical experiences elsewhere and is offered not as an exceptional or extreme case but as an in-depth single case study and a lens for comparison. Although contemporary forms and combinations of conditionalities are new to Ireland, the experience of multiple conditionalities in benefits and housing is not new. Hence, a historical perspective is used to examine contemporary multiple conditionalities in benefits and housing. In the past, conditional regimes for lone parents were justified in terms of moral reformation for first time mothers and avoiding moral contagion of mothers with subsequent pregnancies. In contemporary times, in the case of employment, lone parents are problematised as working part-time and “nesting” on in-work-benefits, and in the case of homelessness, lone parents who prioritise the security of tenure embedded in social housing are accused of “gaming” the system. While acknowledging ambiguities, the paper finds the overlap of welfare and housing discourses contribute, intentionally or unintentionally, to epistemological foundations or understandings of lone parents, shifting public perceptions, and framing them as “problems” to be solved. They simultaneously temper lone parents' expectations. Increased precarity and disempowerment is associated with dual conditionality, and ontological uncertainty is multiplied when experienced cumulatively across employment, social protection, and housing regimes in a context of generally poor public services and labour market precarity and in the historical context of stigmatisation. Nonetheless, lone parents demonstrate considerable agency.     

校园媒体对大学校园文化建设的功能探析

校园媒体对大学校园文化建设的主要功能是舆论引导功能和文化上的同构建设功能。深受世界范围内媒体环境变革的影响,校园媒体对校园文化建设的功能面临新挑战。为应对这一挑战,校园媒体在舆论引导功能上要加强舆论导向与传播效果的统一、党性原则与受众意识的统一;在媒介文化建设上要深入研究“三贴近”方法,办有亲和力的校园权威媒体。本文同时还探讨了新形势下校园媒体新作用的正负效应及相应对策。     

零售商双渠道供应链定价及协调研究

研究了零售商双渠道供应链的定价策略和协调问题,建立制造商和零售商两方博弈模型,分析了集中决策和分散决策两种情境下的定价决策均衡解,并设计收入共享契约来解决零售商双渠道存在的双重边际化效应。结果表明,零售商需要提供合理的收入分配比例才能实现供应链各成员利润的Pareto改进,并最终协调整个双渠道供应链。在双渠道竞争环境下,线上线下不能采取完全同价策略,企业应针对不同渠道的具体情况制定不同的销售价格。     

“双碳”目标下农业生态效率测度及影响因素分析

农业生态效率是农业经济和生态环保协调发展的重要体现。文章首先引入农业碳汇效应,构建农业生态效率测度指标体系;其次,基于2010—2019年中国31个省市面板数据,运用熵权法改进的超效率SBM测算各地区农业生态效率;然后运用面板Tobit模型探究农业生态效率影响因素。结果发现：2010—2019年中国农业生态效率总体呈现平稳上升态势,空间上呈现东北地区最高、东部次之、西部较低、中部最低的分布格局;财政支农程度、工业化程度、农业自然环境、农业机械密度对农业生态效率产生负向影响;农业环境规制、科技支持力度、农业资源禀赋、农业人力资本和农业生产能力对农业生态效率产生正向影响。最后,提出合理投入农业要素资源;促进农业生产增长;加大农业科技研发和推广力度;提高农业劳动力素质等建议。     

A primal dual active set with continuation algorithm for high-dimensional nonconvex SICA-penalized regression

The smooth integration of counting and absolute deviation (SICA) penalty has been demonstrated theoretically and practically to be effective in nonconvex penalization for variable selection and parameter estimation. However, solving the nonconvex optimization problem associated with SICA penalty in high-dimensional setting remains to be enriched, mainly due to the singularity at the origin and the nonconvexity of the SICA penalty function. In this paper, we develop a fast primal dual active set (PDAS) with continuation algorithm for solving the nonconvex SICA-penalized least squares in high dimensions. Upon introducing the dual variable, the PDAS algorithm iteratively identify and update the active set in the optimization using both the primal and dual information, and then solve a low-dimensional least square problem on the active set. When combined with a continuation strategy and a high-dimensional Bayesian information criterion (BIC) selector on the tuning parameters, the proposed algorithm is very efficient and accurate. Extensive simulation studies and analysis of a high-dimensional microarray gene expression data are presented to illustrate the performance of the proposed method.     

Validation of the Learning Transfer System Inventory (LTSI) in the Korean corporate context

Lack of a valid instrument to measure learning transfer predictors has been the major obstacle hindering Human Resource Development (HRD) professionals from moving forward. This problem is one of the lingering HRD issues in South Korea, in which human resources have been strategically emphasized as a critical asset due to the scarcity of natural resources. To address this issue, this study aims at testing the validity and reliability of the data collected with the Korean Learning Transfer System Inventory (LTSI) Version 4. A sample of 753 managers from 16 Korean industries was divided into two subsamples for exploratory and confirmatory factor analyses. Reliability and the effect of common method variance on the factor structure were examined, with the results suggesting that the LTSI is valid for use in the Korean industry.     

产业集群转移研究综述

近年来,伴随着区域分工的不断深化,产业转移、产业集群与产业升级关系的日益密切,产业集群转移这一新趋势是产业集群与产业转移发展到一定阶段的必然产物。只有将产业转移与产业集群结合起来分析,才能对产业集群转移的研究提供较为全面可靠的理论基础及研究动向。基于此,对产业集群转移的内涵、动因、路径以及区域效应进行了梳理,以期为未来的研究提供借鉴与参考。     

农村剩余劳动力转移对下岗人员再就业的冲击

农村剩余劳动力转移和下岗问题是全社会普遍关注的问题,农村剩余劳动力的转移时下岗职工再就业产生了不少的压力,形成了一种激烈的竞争关系,造成下岗职工再就业难度加大的局面。本文在描述农村剩余劳动力的转移对下岗人员带来冲击的同时,也分析了下岗人员受到冲击的原因。通过对农村剩余劳动力和下岗人员情况分析,意在剖析下岗人员失业的原因以及在市场经济条件下如何缓解农村剩余劳动力转移对下岗职工再就业冲击的问题。     

项目制:一种新的国家治理体制(英文)

作为新双轨制的增量部分,项目制旨在通过国家财政的专项转移支付等项目手段,突破以单位制为代表的原有科层体制的束缚,遏制市场体制所造成的分化效应,加大民生工程和公共服务的有效投入。以项目制为核心确立的新的国家治理体制,形成了中央与地方政府之间的分级治理机制,并对基层社会产生了诸多意外后果。项目制所引起的基层集体债务、部门利益化以及体制的系统风险,对于可持续的社会发展将产生重要影响。     

公共企事业单位信息公开的路径选择——新型冠状病毒肺炎疫情引发的法律思考

新冠肺炎疫情中暴露出了信息公开制度的一系列问题,其中作为事业单位的疾控中心和医疗机构是否应当对相关疫情信息进行公开引起了公众的普遍关注。《中华人民共和国政府信息公开条例》对公共企事业单位只作了原则性的规定,现有的“最小存留适用”“最大限度适用”和“脱条例化”的公开路径理论均存在不同的缺陷。公共企事业单位作为一个整体对外虽然与行政机关存在相似性及差异性,但其相互之间也并不完全相同,公开主体与公开目的都存在一定的特殊性及不同之处,因而无法适用统一的公开路径,需遵循“入条例化”和“脱条例化”的双重路径进行信息公开。当公共企事业单位同时符合“实质控制”“公益性”和“弱竞争性”的标准时应当按照“入条例化”路径展开,否则按照“脱条例化”的路径进行公开。
