State of the Art in Risk Analysis of Workforce Criticality Influencing Disaster Preparedness for Interdependent Systems

The objective of this article is to discuss a needed paradigm shift in disaster risk analysis to emphasize the role of the workforce in managing the recovery of interdependent infrastructure and economic systems. Much of the work that has been done on disaster risk analysis has focused primarily on preparedness and recovery strategies for disrupted infrastructure systems. The reliability of systems such as transportation, electric power, and telecommunications is crucial in sustaining business processes, supply chains, and regional livelihoods, as well as ensuring the availability of vital services in the aftermath of disasters. There has been a growing momentum in recognizing workforce criticality in the aftermath of disasters; nevertheless, significant gaps still remain in modeling, assessing, and managing workforce disruptions and their associated ripple effects to other interdependent systems. The workforce plays a pivotal role in ensuring that a disrupted region continues to function and subsequently recover from the adverse effects of disasters. With this in mind, this article presents a review of recent studies that have underscored the criticality of workforce sectors in formulating synergistic preparedness and recovery policies for interdependent infrastructure and regional economic systems.

当代社会思潮对青年的影响——基于对近十年相关研究的述评

研究社会思潮对青年的影响对于新形势下使青年树立和践行社会主义核心价值观具有重要意义。分析近10年的相关文献后发现,当代中国社会对青年有较大影响的思潮主要有新儒家思潮或文化保守主义思潮、实用主义思潮、自由主义思潮、历史主义思潮、新左派思潮、民族主义思潮、民主社会主义思潮和民粹主义思潮。此外还存在诸如后现代主义思潮、女权主义思潮、反全球化思潮、消费主义思潮等对青年影响力稍小但绝不容忽视的思潮。当代社会思潮深刻地影响了青年的信仰和价值观,导致青年政治意识表达方式变迁,影响青年文化体系的形成和变迁,而在这些过程中青年接受社会思潮影响的方式也在发生着变化。社会思潮影响下的青年思想引领主要有思想绝缘法、对象研究法、武器强化法和能力培养法。现有关于社会思潮对青年影响的研究存在着过分侧重定性研究和消极影响、到底如何影响是"黑箱"、研究成果呈现结构失衡等缺陷,需要针对这些缺陷寻找相应的研究进路。     

谭恩美小说《接骨师之女》的国内研究综述

华裔作家谭恩美的小说《接骨师之女》一出版就引起了国内研究者的关注。从最近十年国内公开发表的论文看，不论是文章的数量，还是文章的质量都呈现出持续发展的态势，研究者从不同的角度对作品展开解读。但是，系统回顾小说《接》的国内研究现状，不难发现，当前对该作品的研究仍然存在不少的问题：如主题内容过于集中，研究视角狭窄且多重复，研究的深度有待提高等等。如果这些问题得到妥善解决，小说《接骨师之女》仍然具有较大的研究空间，其前景也令人期待。     

PROVIDING GLOBAL PUBLIC GOODS: ELECTORAL DELEGATION AND COOPERATION

This study experimentally examines the effect of electoral delegation on providing global public goods shared by several groups. Each group elects one delegate who can freely decide on each group member's contribution to the global public goods. Our results show that people mostly vote for delegates who assign equal contributions for every group member. However, in contrast to standard theoretical predictions for our delegation mechanism, unequal contributions across groups drive cooperation down over time, and it decreases efficiency by almost 50% compared to the selfish benchmark. This pattern is not driven by delegates trying to exploit their fellow group members, as indicated by theory. It is driven by conditional cooperation of delegates across groups. Since one of the potential sources of the resulting inefficiency is the polycentric nature of global public goods provision together with other‐regarding preferences, we use the term P‐inefficiency to describe our finding.

四川盆地雷口坡组层序岩相古地理

针对四川盆地各矿区雷口坡组地层划分方案不统一，且受早印支运动的影响，雷口坡组顶部岩溶带地层垮塌破坏，造成地层内幕划分及岩相古地理恢复困难的难题，以层序地层学理论与方法为指导，重新厘定了盆地内雷口坡组的地层划分方案，以四级层序为作图单元进行层序岩相古地理重建。高精度的层序岩相古地理研究表明，雷口坡期四川盆地处于局限–蒸发海环境，在川西北一带靠近松潘—甘孜海槽一带发育有台地边缘，台地内部颗粒滩和台地边缘颗粒滩构成了雷口坡组的勘探主体。岩相古地理的演化表明，雷口坡组沉积时期盆地底形发生了东倾向西倾“跷跷板”式的转换，在层序I 早期仍保持了早三叠世西高东低的地形格局，至层序III 沉积期东倾趋势消失，层序IVV 沉积时期盆地内隆凹格局略具雏形。伴随着构造挤压运动的加剧，从层序VI 开始盆地底形隆凹格局分异加剧，形成巨厚膏盐盆，膏盐盆沉积中心在层序VIX 沉积时期具有明显西移的趋势。     

Optimal control strategies for dividend payments and capital injections in compound Markov binomial risk model with penalties for deficits

We consider the compound Markov binomial risk model. The company controls the amount of dividends paid to the shareholders as well as the capital injections in order to maximize the cumulative expected discounted dividends minus the discounted capital injections and the discounted penalties for deficits prior to ruin. We show that the optimal value function is the unique solution of an HJB equation, and the optimal control strategy is a two-barriers strategy given the current state of the Markov chain. We obtain some properties of the optimal strategy and the optimal condition for ruining the company. We offer a high-efficiency algorithm for obtaining the optimal strategy and the optimal value function. In addition, we also discuss the optimal control problem under a restriction of bounded dividend rates. Numerical results are provided to illustrate the algorithm and the impact of the penalties.     

空间批评视角下的《生日》

从空间批评视角看,文本中的空间不再是静止的＂容器＂,而是一种蕴含多维文化信息的指涉系统,注重文本中空间的社会、文化属性。在美国华裔作家雷祖威的短篇小说《生日》中,与华裔青年华莱士·王的爱情故事相关的几个空间场景不仅再现了华裔的现实生活世界,更充分展示了他们居于社会边缘的处境与内心疏离的痛苦。     

社会组织创新研究述评

公民社会部门的出现是20世纪最重要的社会创新，是一场深刻的“全球结社革命”。社会组织研究国外源远流长，著述丰硕，影响深远；国内在社会管理体制创新的推动下，社会组织创新日渐吸引眼球。整体来看，研究的学科、研究的领域、研究的成员在不断增多，研究趋势渐从社会组织管理创新的思想观念、创新路径、管理体制、困境与出路等方面，逐渐转向推进社会管理创新的政治和社会层面，以期促进各种认同的和谐共生关系的形成。
