环境约束下的化石能源跨期开采路径比较研究

考虑化石能源开发和使用的环境外部性与代际外部性,在动态最优开采模型基础上构建含有环境污染因子的跨期配置模型,比较考虑环境制约因素前后的开采路径,证明环境约束对化石能源消耗有复杂影响,环境作为政策工具可以调节化石能源开采强度,在一定程度上缓解了资源的稀缺性和延长了资源耗竭时间,为具有经济价值的可再生能源的出现赢得时间。应用中国相关历史数据,发现实际上环境约束没有抑制化石能源消耗,偏离了理论分析预期目标。据此提出加快矿产资源税费改革、加大环境污染治理投资、优化投资结构、建立科学环境补偿制度、促进技术进步的政策建议。     

可再生能源开发利用中的政府规划检讨及改进——基于系统论的分析

可再生能源的开发利用是一项庞大而复杂的系统工程,科学的政府规划可以有效避免其运作的盲目和不当。然而,我国可再生能源政府规划,包括国家规划和区域规划,都存在诸多欠缺。在可再生能源开发利用政府规划的制订中,应运用系统论的方法进行多层面考量,充分考虑政府规划的"外部性"、国家规划的"整体性"与"全局性"、区域规划的"地域性"与"特色性"。     

基于不同所有权企业的知识转化创新与绩效比较研究

基于创新理论及知识管理理论,建立了企业绩效与知识转化创新的结构方程模型.据此对国有企业和非国有企业中知识转化创新与绩效的关系进行了比较研究,发现2种所有权性质企业中知识转化和创新与企业绩效之间的关系差异显著.由此,对于中国企业知识创新战略决策的制定过程,所有者性质的影响不容忽视.     

以企业能力为中介的联盟类型与技术创新方式关系实证研究

从资源基础观构建联盟类型、企业能力(开发能力和探索能力)和技术创新方式相互关系的模型,以重庆等6个地区500家制造业企业为调研对象,运用结构方程模型对所获数据进行实证分析。结果表明:市场联盟提供的市场资源利于开发能力的提升,技术联盟提供的技术资源利于探索能力的发展;开发能力与渐进创新方式正相关,探索能力与突变创新方式正相关;市场联盟提供的市场资源有助于渐进创新方式,技术联盟提供的技术资源有助于突变创新方式。     

绩效薪酬对团队成员探索行为和利用行为的影响

基于期望理论和公平理论视角,从团队层面对绩效薪酬与团队成员探索性创新行为(简称探索行为)和利用性创新行为(简称利用行为)的关系进行跨层次研究,检验团队薪酬水平的调节效应.采用上下级问卷匹配的方式搜集调查数据,运用HLM 6.0对来自51名团队主管和329名团队成员的匹配数据进行统计分析.研究结果表明,绩效薪酬与探索行为之间为倒U形关系,与利用行为之间为正相关关系.薪酬水平调节绩效薪酬与探索行为的关系,在高薪酬水平情境下,高强度绩效薪酬对探索行为的负向效应更弱;在低薪酬水平情境下,高强度绩效薪酬对探索行为的负向效应更强.薪酬水平正向调节绩效薪酬与利用行为之间的关系,团队薪酬水平越高,绩效薪酬与利用行为之间的正向关系越强.为绩效薪酬有效性研究提供了一个新的研究视角,研究结论对指导企业优化团队薪酬决策及改进创新管理具有重要的实践价值.     

Daisee: Adaptive importance sampling by balancing exploration and exploitation

We study adaptive importance sampling (AIS) as an online learning problem and argue for the importance of the trade-off between exploration and exploitation in this adaptation. Borrowing ideas from the online learning literature, we propose Daisee, a partition-based AIS algorithm. We further introduce a notion of regret for AIS and show that Daisee has $𝒪(\sqrt{T}{(\log T)}^{\frac{3}{4}})$ cumulative pseudo-regret, where $T$ is the number of iterations. We then extend Daisee to adaptively learn a hierarchical partitioning of the sample space for more efficient sampling and confirm the performance of both algorithms empirically.     

社会主义与机会平等——约翰·罗默的正义理论

约翰·罗默运用分析方法及模型构建、博弈论等方法，界定了撤出式博弈的一般剥削观以及社会必要剥削等概念。出于对作为剥削根源的财产关系的重视，罗默转向分配正义研究，并提出社会主义的本质在于机会平等。罗默的机会平等主张根据外部不可控因素将社会成员划分为不同类型，接受每一类型内部成员的收入不平等，同时实现不同类型间相同百分位数者的收入平等，使努力程度相等而非努力数量相等的人获得相等回报。以机会平等为目标，罗默还设计了以息票为主要特色的证券市场社会主义方案，致力于兼顾平等与效率，使公民分享经济利润的机会平等，同时避免财富继承的代际不平等。罗默的正义理论和研究方法别具特色，为坚持和发展马克思主义提供了正反两方面的借鉴意义。     

荡气回肠的人格尊严——毕飞宇的小说《推拿》论析

毕飞宇的长篇小说《推拿》塑造了一群有高度尊严感的盲人推拿师形象,在题材的开拓上具有重大意义。作者站在人文主义的立场上,通过描写盲人推拿师的日常生活和情感追求等,对健全人格极力张扬,对尊严高度礼赞,对犬儒主义风气严厉批判,显示出高度的责任感。     

The ‘virtuous’ cycle of parental empowerment: Partnering with parents to safeguard young people from exploitation

When young people are sexually exploited, parents and professionals alike can feel uncertain about how to balance the need to protect the child's rights to agency and autonomy while also reducing the risk of harm. Despite the shared interest in keeping young people safe, there remains a substantial gap in the research literature about how practitioners engage parents to increase capacity to safeguard their children, particularly within the context of a child protection system ill-equipped to address forms of extrafamilial harm such as child sexual exploitation. This paper aims to contribute to understanding how professionals effectively engage parents by drawing upon evidence from research evaluations of two programmes in rural/urban North and urban South locations in England, both providing specialist support to parents/carers of sexually exploited children and young people. Through interrogating elements of effective support work evidenced across both programmes, a set of emerging key themes are presented, proposing that parent support and engagement can create a ‘virtuous’ cycle, whereby families are strengthened and are better able to protect their children from sexual exploitation and other forms of extrafamilial harm.     

How are policies implemented in children's services? Developing an initial programme theory to evaluate the implementation of the new Child Sexual Exploitation guidance in Wales

Although children's social care is an area rich in guidance, there is very little research looking at the implementation of new policies in the United Kingdom. In this article, we report on the first stage of a realist evaluation of the implementation of the new Safeguarding Children from Child Sexual Exploitation guidance in Wales. We discuss the development of an initial programme theory, for which we conducted semi-structured interviews with practitioners and managers in three local authorities. We developed programme theories across three areas: policy nature and development, implementation plans and organizational context. Findings suggest that, for policies to produce a significant impact on practice, they need to be sufficiently different to social workers' current perceptions of practice. Second, we found that the coordination between national and local policies is critical for successful implementation as contradictions between them might lead to confusion in what local teams should prioritize. Finally, our findings highlight the importance of effective communication of policy changes, as well as a supportive organizational culture to strengthen implementation in local contexts. These findings illustrate the complexity of policy implementation and the need for policymakers to consider the meaningful involvement of local practitioners in national policy development.
