批判性重构:莱斯关于“人之存在方式”的研究

当今社会最重大的时代主题就是人之存在问题。莱斯是最早用马克思主义理论透视人之存在方式问题的生态学马克思主义者。对于人之存在方式的研究,莱斯有其独特的逻辑理路与研究范式。他准确预言了高集约度市场布局下人的异化存在已经由生产领域转向消费领域,并判明主体存在方式由理性控制走向非理性狡计的历史趋势。莱斯所描绘的生态社会主义蓝图看似极具浪漫主义的乌托邦情结,但他所开启的从生态学马克思主义视域探究人之存在方式问题的研究路向影响深远。     

A New Methodology for Before–After Safety Assessment Using Survival Analysis and Longitudinal Data

The widely used empirical Bayes (EB) and full Bayes (FB) methods for before–after safety assessment are sometimes limited because of the extensive data needs from additional reference sites. To address this issue, this study proposes a novel before–after safety evaluation methodology based on survival analysis and longitudinal data as an alternative to the EB/FB method. A Bayesian survival analysis (SARE) model with a random effect term to address the unobserved heterogeneity across sites is developed. The proposed survival analysis method is validated through a simulation study before its application. Subsequently, the SARE model is developed in a case study to evaluate the safety effectiveness of a recent red‐light‐running photo enforcement program in New Jersey. As demonstrated in the simulation and the case study, the survival analysis can provide valid estimates using only data from treated sites, and thus its results will not be affected by the selection of defective or insufficient reference sites. In addition, the proposed approach can take into account the censored data generated due to the transition from the before period to the after period, which has not been previously explored in the literature. Using individual crashes as units of analysis, survival analysis can incorporate longitudinal covariates such as the traffic volume and weather variation, and thus can explicitly account for the potential temporal heterogeneity.

The identification of logistic regression models with errors in the variables

The simple logistic regression model with normal measurement error and normal regressor is shown to be identifiable without any extra information about the measurement error. The multiple logistic regression model with more than one regressor variable measured with error is not identifiable. If the covariance matrix of the measurement error is known up to a scalar factor, the model is identified. Further we discuss why in spite of the identifiability the models cannot be estimated in a reasonable way without extra information about the measurement error.     

Adolescent Protective Factors Promoting Resilience in Young Adults at Risk for Depression

In a longitudinal, community-based study, adolescent protective factors for those at risk for depression were identified that were associated with resilient outcomes in young adulthood. For those with childhood risk factors for major depression, significant protective factors included family cohesion, positive self appraisals, and good interpersonal relations. Findings may help inform the development of prevention and treatment programs for adolescents vulnerable to depression. Implications for future research and clinical practice are discussed.     

Luxembourg's Foreign Policy: Does Small Size Help or Hinder?

As a very small state, Luxembourg would not appear to qualify as an influential foreign policy actor either in Europe or the world. Yet the country's international influence has long belied its reputation as a small state. This article reviews the literature on small-state foreign policy and finds that it offers numerous contradictory conclusions. As a case study it then addresses Luxembourg in the 1990s, with particular attention to two themes: its active participation in the European Union (EU) and its policies directed at maintaining economic prosperity. The paper goes on to explain Luxembourgish foreign policy behaviour through three levels of analysis and assesses to what extent smallness is a benefit or a hindrance to Luxembourg's success in meeting its international goals.     

对西部地区土地整理若干问题的思考

我国西部地区地域辽阔,地质地貌复杂,人少地多,土地利用相对粗放,是我国未开发利用土地的主要分布区,同时也是气候干旱多灾、水土流失严重、自然条件较差、生态环境脆弱的地区.随着国家西部大开发战略的实施,各项建设事业对土地的需求将会十分旺盛.如何根据西部地区特殊的自然、经济和社会条件来讨论西部土地资源的利用形式、利用方式以及生态环境保护,是西部大开发中首先应该思考的问题.
