基于遗传粒子群算法的堆垛机作业路径优化

通过查慎行对《瀛奎律髓》中陆游诗歌的评点可以看出，他在章法、用典、字法、句法、对仗等方面对陆游诗歌多有称赏，对陆游学古不化及艺术上的瑕疵亦多有批评，总体上体现出较为客观的批评态度。在查慎行的诗学理论体系中，陆游的地位经历了一个由高到低的过程。查慎行对自己青年时期偶像的批评与颠覆，体现出其晚年诗学理论的转变与成熟。     

A cyclical view of the relationship between corporate governance and strategic management

The vast majority of research on the relationship between corporate governance and strategic management focuses on the impact of corporate governance on strategic management. In this article we propose a cyclical model, highlighting that strategic decisions can also affect corporate governance through shaping firm ownership structure. We discuss the impacts of strategic decisions on firm ownership structure and corporate governance in the contexts of publicly traded firms, private firms, and the privatization of state-owned enterprises. We hope that our cyclical model can promote researchers to develop a more complete view about the relationships between strategic management, ownership structure, and corporate governance.     

基于供需分析的新生代农民工职业化研究

借鉴经济学中供给和需求的分析视角,对新生代农民工职业化的研究表明:政府对职业化的贡献度最大,是推动新生代农民工职业化的主导力量,要重点推动户籍制度改革,完善各项制度保障,构建现代化职业教育体系。企业是推动新生代农民工职业化的实践场所,除了考虑为支付新生代农民工职业化成本而承担新生代农民工违约的风险,还要承担起相应的社会责任。新生代农民工要通过快速职业化提高职业技能水平,保持职业的相对稳定,积极参加职业教育,适应城镇化和工业化快速发展的迫切需要。     

Trauma and health risk behaviors in people with severe mental illness

The current study tests the association between a composite measure of unsafe sex and sharing syringes for drug use with six of the more common lifetime traumatic/stressful events in 421 community mental health clients with severe mental illness (SMI) while controlling for psychiatric symptoms and related problems. A small but significant proportion of respondents said they had injected drugs with a shared needle in their lifetime (30, 7.2%), and a much larger proportion of respondents had engaged in unprotected sex (165, 39.2%). Unprotected sex and needle sharing were significantly correlated (Spearman’s rho = .20, p < .01). Frequency of lifetime traumatic events that occurred at least once was reported by one third to three quarters of clients depending on type of trauma. Regression analysis revealed that substance abuse and lifetime homelessness were significantly correlated with health risk behaviors. Practitioners need to be continuously vigilant to comorbid substance use and the housing needs of people with SMI. Limitations of the study include its cross-sectional design.     

薪酬参照体的效应研究:基于多表征的路径模型与相对重要性

参照体选择在分配公平、薪酬满意研究中扮演重要角色,而以往研究多是关注焦点对象与参照体在薪酬上的数量差异。本文认为,参照体"数量差异"并不能完整表征参照体的效应,为此提出了"信息知晓度"、"判断关联性"、"比较频率"、"数量差异"等四类表征,在理论基础上构造路径模型与研究假设。实证研究表明,信息知晓度、判断关联性正向影响特定参照体的比较频率;数量差异正向影响分配公平、薪酬水平满意,比较频率负向影响分配公平、薪酬水平满意。通过三种研究路径的比较研究证实,自我生活成本等七类参照体相对重要。未来亟需就参照体选择的相关机制在纵贯上、在不同的组织情境下及考虑个体差异等方面予以深入考察。

Evidence-based practice in Chinese social work: overcoming language and developmental barriers

This scoping review followed Cochrane guidelines to comprehensively assess the use and understanding of Evidence-Based Practice (EBP) in Chinese social science literature. We conducted a research across three electronic databases and three major social science journals for the studies published between 2004 and 2016. Chinese social work literature demonstrates a precise understanding of EBP defined as a process, but it lacks comprehensive discussions about EBP that extend beyond basic principles and process definitions. We identified language barriers and developmental issues for social work in China that contribute to these incomplete discussions. We examined the importance of broadening and enriching the discussions around EBP, especially for Chinese educators, researchers, and clinicians involved with empirically supported treatments. We also consider the implications of our findings for the development of social work in China.     

Dynamic Forecasting Conditional Probability of Bombing Attacks Based on Time‐Series and Intervention Analysis

In recent years, various types of terrorist attacks occurred, causing worldwide catastrophes. According to the Global Terrorism Database (GTD), among all attack tactics, bombing attacks happened most frequently, followed by armed assaults. In this article, a model for analyzing and forecasting the conditional probability of bombing attacks (CPBAs) based on time‐series methods is developed. In addition, intervention analysis is used to analyze the sudden increase in the time‐series process. The results show that the CPBA increased dramatically at the end of 2011. During that time, the CPBA increased by 16.0% in a two‐month period to reach the peak value, but still stays 9.0% greater than the predicted level after the temporary effect gradually decays. By contrast, no significant fluctuation can be found in the conditional probability process of armed assault. It can be inferred that some social unrest, such as America's troop withdrawal from Afghanistan and Iraq, could have led to the increase of the CPBA in Afghanistan, Iraq, and Pakistan. The integrated time‐series and intervention model is used to forecast the monthly CPBA in 2014 and through 2064. The average relative error compared with the real data in 2014 is 3.5%. The model is also applied to the total number of attacks recorded by the GTD between 2004 and 2014.     

戴维森意义理论的主要思想导源

戴维森意义理论具有明显的思想继承性,主要表现在:弗雷格的真值条件论是其基本立足点,塔尔斯基真之语义论的约定-T模式充当其形式表征基础,蒯因的彻底翻译理论成为其经验解释的理论基础。正是由于戴维森善于借鉴这些影响深远的思想成果,使其意义理论呈现出一种解释性的真理论而潜在地具有非凡的理论优势和影响力。     

《利维坦》中国家主权与个人自我保存权之间的张力

在《利维坦》中,国家主权与个人自我保存权是两个核心概念。出于维护个人自我保存权的目的,霍布斯构建出一个强有力的国家主权。但是,国家主权和自我保存权之间却存在着严重的张力:一方面,不受制约的国家主权必然导致主权者权力的滥用,进而会侵害个人的自我保存权;另一方面,对个人自我保存权的过分强调使臣民对抗法律和主权具有了道义上的依据,这势必损毁国家主权的基础。《利维坦》中逻辑困境的症结在于:一方面,霍布斯没有把主权的至高无上与治权的应受制约区分开来;另一方面,霍布斯对于自然状态下与国家状态下的自我保存权未作应有的区分。
