The Relevance of Modernity to Contemporary East Asia: An Outline

This article offers a framework for exploring the relevance of modernity to contemporary East Asia. I first examine different conceptualizations of modernity, paying special attention to Eisenstadt's influential concept of multiple modernities. Second, I point out the limitations and flaws of Eisenstadt's theory by drawing on nationalist politics in East Asia as an illustrative case. In particular, I examine the so-called “history perception problem,” which has been created by war and shaped by the legacies of war, to demonstrate the peculiar features of modernity in East Asia. Third, I use the works by three scholars as examples to show how intellectuals in China, South Korea, and Taiwan respond to the tensions between universalism and particularism, which, as a whole, reflect what can be called “East Asian modernity.” And finally, I try to respond to the controversial but fashionable question that is peculiar to East Asia: can modernity be overcome? It is argued that East Asia can be understood through the lens of modernity, and vice versa. Nowadays, modernity has become a global condition in both geographical and topological senses. It is not something to be overcome, but a condition that we all live in and should learn to live with, here and now.     

高校少数民族毕业生就业问题及对策研究——以西南民族大学为例

大学生就业问题近年来成为社会各界关注的热点问题,少数民族大学毕业生的就业问题因其既具有共性,又带有特性,更应成为关注的焦点。本文基于对西南民族大学少数民族毕业生就业问题的调研,发现当前成都地区高校少数民族毕业生一定程度存在热衷大城市就业,沟通能力相对不足,从事工作与所学专业不对口,易受到不公对待等就业问题。究其原因,我们认为与少数民族大学毕业生的传统择业观、汉语水平、学校的专业设置以及用人单位的不当认识有关。为此,本文提出政府应加大对少数民族大学毕业生就业的关注程度;学校应提高少数民族大学生的综合素质;社会应创造公平公正的就业环境;少数民族大学生应提升自身能力、转变择业观念等相关对策建议。     

社会工作专业教学组织机制：问题与选择

优化教学组织机制是提高社会工作专业教育质量不可或缺的重要一环。面对社会工作专业课堂教学和实践教学他组织与自组织相分离的现实困境,教师要科学选择介入策略,勇于革新教学方法,以实现教学组织机制的优化。     

社会角色理论视域下高校问题学生行为失范

高校"问题学生"行为失范已得到社会的普遍关注,基于前人研究的基础,立足客观实际,开辟新视角,将社会角色理论引入对这一问题的研究,不仅对"问题学生"和"行为失范"进行了重新界定,从角色转换、角色冲突、角色错位、角色失败四个方面分析了高校"问题学生"行为失范产生的缘由,并提出了相应的对策。     

SOCIAL WORK EDUCATION: THE AVAILABILITY OF ALCOHOL‐RELATED COURSE CURRICULUM AND SOCIAL WORKERS' ABILITY TO WORK WITH PROBLEM DRINKERS

An explanatory cross‐sectional investigation was employed to assess how well masters‐level social work (MSW) programs in the State of New York prepare students for practice with problem drinkers. The following areas were explored: (1) the incorporation of alcohol‐related coursework and field placement opportunities within MSW programs; (2) the relationship between students' completion of alcohol‐related courses and field placements and their subsequent ability to diagnose clients with alcohol problems, their willingness to work with problem drinkers, and their levels of alcohol‐related knowledge; and (3) subjects' levels of alcohol‐related knowledge in relation to their diagnostic ability and their willingness to work with problem drinkers. The sample consisted of 89 MSW‐level social work practitioners, who were active members of the New York State Chapter of the National Association of Social Workers (NASW) during the fall of 2005. Fewer than 3% of the sample reported the completion of an alcohol‐related course as a mandatory degree requirement and only 29.5% of the sample acknowledged the completion of an alcohol‐related field placement. These findings suggest that a possible gap exists in what social workers are being taught and what they need to know to successfully work with problem drinkers. The findings indicate that clients with alcohol problems are at risk of going untreated due to social workers' inability to correctly diagnose them as a result of insufficient training in the area of alcohol studies.     

Pathways of disadvantage: Explaining the relationship between maternal depression and children’s problem behaviors

A large body of literature documents that children of depressed mothers have impaired cognitive, behavioral, and health outcomes throughout the life course, though much less is known about the mechanisms linking maternal depression to children’s outcomes. In this paper, I use data from the Fragile Families and Child Wellbeing Study to estimate and explain the consequences of maternal depression for 5-year-old children’s internalizing and externalizing problem behaviors. Ordinary least squared (OLS) regression models and propensity score models show that children exposed to both chronic and intermittent maternal depression have more problem behaviors than their counterparts with never depressed mothers. Results also show that economic resources and maternal parenting behaviors mediate much of the association between maternal depression and children’s problem behaviors, but that relationships with romantic partners and social support do little to explain this association. This research extends past literature by illuminating some mechanisms through which maternal depression matters for children; by utilizing longitudinal measures of depression; by employing rigorous statistical techniques to lend confidence to the findings; and by using a large, diverse, and non-clinical sample of children most susceptible to maternal depression. Given that early childhood problem behaviors lay a crucial foundation for short- and long-term life trajectories, the social consequences of maternal depression may be far-reaching.

An upper bound on the minimal total cost of the transportation problem with varying demands and supplies

In general cases, to find the exact upper bound on the minimal total cost of the transportation problem with varying demands and supplies is an NP-hard problem. In literature, there are only two approaches with several shortcomings to solve the problem. In this paper, the problem is formulated as a bi-level programming model, and proven to be solvable in a polynomial time if the sum of the lower bounds for all the supplies is no less than the sum of the upper bounds for all the demands; and a heuristic algorithm named TPVDS-A based on genetic algorithm is developed as an efficient and robust solution method of the model. Computational experiments on benchmark and new randomly generated instances show that the TPVDS-A algorithm outperforms the two existing approaches.     

A shelf-space optimization model when demand is stochastic and space-elastic

The more customer demand is impulse-driven, the more it is space-dependent and the more it is subject to variation. We investigate the corresponding problem of retail shelf-space planning when demand is stochastic and sensitive to the number and position of facings. We develop a model to maximize a retailer׳s profit by selecting the number of facings and their shelf position under the assumption of limited space. The model is particularly applicable to promotional or temporary products.We develop the first optimization model and solution approach that takes stochastic demand into account, since the current literature applies deterministic models for shelf-space planning. By the means of an innovative modeling approach for the case with space- and positioning effects and the conversion of our problem into a mixed-integer problem, we obtain optimal results within very short run times for large-scale instances relevant in practice. Furthermore, we develop a solution approach to account for cross-space elasticity, and solve it using an own heuristic, which efficiently yields near-optimal results. We demonstrate that correctly considering space elasticity and demand variation is essential. The corresponding impacts on profits and solution structures become even more significant when space elasticity and stochastic demand interact, resulting in up to 5% higher profits and up to 80% differences in solution structures, if both effects are correctly accounted for. We develop an efficient modeling approach, compare the model results with approaches applied in practice and derive rules-of-thumb for planners.     

Model selection consistency of U-statistics with convex loss and weighted lasso penalty

In the paper we consider minimisation of U-statistics with the weighted Lasso penalty and investigate their asymptotic properties in model selection and estimation. We prove that the use of appropriate weights in the penalty leads to the procedure that behaves like the oracle that knows the true model in advance, i.e. it is model selection consistent and estimates nonzero parameters with the standard rate. For the unweighted Lasso penalty, we obtain sufficient and necessary conditions for model selection consistency of estimators. The obtained results strongly based on the convexity of the loss function that is the main assumption of the paper. Our theorems can be applied to the ranking problem as well as generalised regression models. Thus, using U-statistics we can study more complex models (better describing real problems) than usually investigated linear or generalised linear models.
