城市交通中车辆择路行为实证研究

随机、时变的交通流分布,偶发的交通事故等因素导致了路径随机的车辆旅行时间,也决定了现实城市交通网络中只存在随机最短路.已有的路径选择研究大都假设人们力求选择最短路,而通过实际调查发现:人们的择路行为依赖出行情景,随出行目的、约束时间、对路径的熟悉程度以及路径的不确定程度而变化.验证了城市交通中人们在不确定环境下的择路行为也符合展望理论.     

Fetishizing the health sciences: Queer theory as an intervention

Queer theory often falls impotent in its palatability across disciplinary lines. I offer a conceptual article that interrogates the dis-ease and divide when considering queer theory in and for the health sciences. In so doing, I look to foster a process of making queer theory more tenable to applied practice—and to make practice in social work, at least, more queer. The exemplar of HIV is deconstructed as a preeminent discourse and health disparity. In the end, it is argued that queer theory may be an essential intervention in the arsenal of the helping professions.     

Double trouble: work–family conflict and well-being for second job holders

The purpose of this study was to provide an initial investigation into the work–family conflict (WFC) experiences of individuals who hold a second job. Specifically, we proposed two opposing theoretical arguments regarding the relationship between WFC and four measures of well-being: life satisfaction, physical health, emotional exhaustion, and exercise for individuals who hold two jobs. In a sample of individuals working two jobs, we tested whether the effects of WFC arising from the first job and from the second job exerted an additive or interactive effect on employee well-being. Our results indicated that for emotional exhaustion, physical symptoms, and life satisfaction, the effects of WFC from two jobs are interactive; but that for exercise, the effects of WFC from two jobs are additive. In both cases, the additional WFC experienced as a result of working a second job contributed to the prediction of employee well-being over and above WFC from the first job. Results are discussed within the context of relevant theory, and suggestions are made for future research.     

Love thy neighbour: Social identity and public support for humanitarian aid

Humanitarian aid can be contentious. Should finite national resources be sacrificed to serve the needy abroad? Social identity theorists argue that identification with a superordinate group, in this case the larger world community, should increase individual support for policies such as international humanitarian assistance. However, individuals can simultaneously associate with multiple identities. How does the combination of world and national identities affect support for humanitarian assistance? Using cross‐national survey data, we find evidence that support for international humanitarian aid is highest among those with a strong world identity and weak national identity relative to other identity combinations, though even those with a strong world identity and strong national identity can be supportive of aid.     

医古文翻译：基于翻译适应选择论视角

随着中医的发展逐渐走向国际化,关于中医的中外交流日益增多,而对中医的翻译却又难以达到令人满意的水平。其难点主要在于保证医学信息的正确与完整的同时,又要将中医中文化内涵准确地传达。本文试图运用翻译适应选择论这一新译论,将医古文译者在翻译过程中的适应与选择通过语言维、文化维、交际维这三大维度进行分析和说明,以期为医古文翻译的障碍找出解决办法,提高翻译质量,促进文化交流。     

Evaluating Probabilistic Forecasts with Bayesian Signal Detection Models

We propose the use of signal detection theory (SDT) to evaluate the performance of both probabilistic forecasting systems and individual forecasters. The main advantage of SDT is that it provides a principled way to distinguish the response from system diagnosticity, which is defined as the ability to distinguish events that occur from those that do not. There are two challenges in applying SDT to probabilistic forecasts. First, the SDT model must handle judged probabilities rather than the conventional binary decisions. Second, the model must be able to operate in the presence of sparse data generated within the context of human forecasting systems. Our approach is to specify a model of how individual forecasts are generated from underlying representations and use Bayesian inference to estimate the underlying latent parameters. Given our estimate of the underlying representations, features of the classic SDT model, such as the receiver operating characteristic (ROC) curve and the area under the ROC curve (AUC), follow immediately. We show how our approach allows ROC curves and AUCs to be applied to individuals within a group of forecasters, estimated as a function of time, and extended to measure differences in forecastability across different domains. Among the advantages of this method is that it depends only on the ordinal properties of the probabilistic forecasts. We conclude with a brief discussion of how this approach might facilitate decision making.     

以孝道文化为核心的崇德向善理念之理论建构

习近平总书记高度重视道德建设，多次强调儒家思想在政府建设新型社会主义价值观过程中的重要地位。以孝道文化为核心的崇德向善理念的理论建构，可从三个方面进行分析论证：其研究视角是重视孝道文化在儒家思想中的核心地位，领会儒家思想占据政府建设新型价值观重要地位的明显趋势，从当代社会主义公民价值观的内涵定义来界定这一理论；其理论建构是以崇德向善为理念、以孝道文化为核心、以家庭教育为平台的结构框架；其对策和措施包括坚持“顶层设计、政府主导”的原则，采取“家庭为主、学校为辅”的教育方式，倡导“民俗为媒、繁荣节庆”的教育形式，强化“市场搭台、文化立国”运行机制。     

CEO duality and firm performance: The moderating roles of other executives and blockholding outside directors

This study examines how the effect of CEO duality on firm performance is affected by two internal governance forces – namely other executives in the top management team and blockholding outside directors. Results based on a longitudinal dataset from the U.S. computer industry were consistent with my hypotheses. Specifically, I found that the effect of CEO duality was negative when the CEO had dominant power relative to other executives and when the board had a blockholding outside director, but was nonsignificant otherwise. This study enriches our understanding of the effect of CEO duality, and helps reinforce the call for the nonduality structure as the default choice and put the burden of proof on those who wish to justify otherwise on special grounds.     

罗尔斯分配正义及对我国分配问题的启示

罗尔斯的正义论不只是对传统正义观的继承,更是对其的创新和发展。它较为深刻地论述了个人与社会关系这一带有普遍意义的社会基本问题。分配正义是转型期中国社会遇到的核心问题,是诱发各种社会矛盾的根源之一。罗尔斯所提出的解决分配不正义的基本原则和设想,给我们勾画了一个自由又平等的社会愿景。其《正义论》可以说给我们提供了一个解决社会不正义的极其优化的解决方案。
