Using the integrative model of behavioral prediction to understand college students’ STI testing beliefs,intentions, and behaviors

ABSTRACT

Objectives: To identify salient behavioral determinants related to STI testing among college students by testing a model based on the integrative model of behavioral (IMBP) prediction. Participants: 265 undergraduate students from a large university in the Southeastern US. Methods:Formative and survey research to test an IMBP-based model that explores the relationships between determinants and STI testing intention and behavior. Results: of path analyses supported a model in which attitudinal beliefs predicted intention and intention predicted behavior. Normative beliefs and behavioral control beliefs were not significant in the model; however, select individual normative and control beliefs were significantly correlated with intention and behavior. Conclusions: Attitudinal beliefs are the strongest predictor of STI testing intention and behavior. Future efforts to increase STI testing rates should identify and target salient attitudinal beliefs.     

Decision Support System of Truck Routing and Refueling: A Dual‐Objective Approach

The variable‐route vehicle‐refueling problem (VRVRP) is a variant of the network‐flow problem which seeks, for a vehicle traveling from origin s to destination d, both the route and the refueling policy (sequence of fuel stations to use between s and d) that jointly minimize the fuel cost of operating the vehicle. Commercial‐grade decision support systems that solve the VRVRP are widely used by motor carriers, but they provide heuristic solutions only. Exact methods are available from the academic side, but because they focus on minimizing costs, they tend to cut fuel costs in exchange for increased vehicle miles (which can increase fuel consumptions and pollutants emission). We propose a new approach to the VRVRP that allows carriers to jointly seek the two possibly conflicting goals; minimizing fuel cost and vehicle miles. Computational testing shows that our approach (i) outperforms the commercial software products in both goals, and (ii) finds solutions that require significantly less vehicle miles than those given by the exact method proposed in the academic literature, without incurring unacceptable increases in fuel cost.

股指期货信息内含股价变动信息的挖掘 ――小波框架与支持向量回归的金融建模应用

 内容提要：中国股指期货的推出指日可待,交易者多了一种投资工具的同时也带来了新的风险。建立准确的金融时间序列预测模型是逐利及避险的方法之一,一直是学者专家研究的热点。本研究结合小波转换与支持向量回归,提出一个二阶段时间序列预测模型。先以离散小波框架将预测变量分解成不同尺度的多个子序列,揭示隐藏在预测变量内的信息,再以支持向量回归为工具,以这些子序列为预测变量建构SVR模型。本研究以日经225指数开盘价为预测目标,以期货开盘价为预测变量对模型进行实证研究,结果显示,该模型的预测绩效比单纯SVR模型及随机漫步模型好。未来可尝试以不同的基底函数作进一步研究。

A Bayesian estimate of the concordance correlation coefficient with skewed data

Concordance correlation coefficient (CCC) is one of the most popular scaled indices used to evaluate agreement. Most commonly, it is used under the assumption that data is normally distributed. This assumption, however, does not apply to skewed data sets. While methods for the estimation of the CCC of skewed data sets have been introduced and studied, the Bayesian approach and its comparison with the previous methods has been lacking. In this study, we propose a Bayesian method for the estimation of the CCC of skewed data sets and compare it with the best method previously investigated. The proposed method has certain advantages. It tends to outperform the best method studied before when the variation of the data is mainly from the random subject effect instead of error. Furthermore, it allows for greater flexibility in application by enabling incorporation of missing data, confounding covariates, and replications, which was not considered previously. The superiority of this new approach is demonstrated using simulation as well as real‐life biomarker data sets used in an electroencephalography clinical study. The implementation of the Bayesian method is accessible through the Comprehensive R Archive Network. Copyright © 2015 John Wiley & Sons, Ltd.     

对于构建中印自由贸易区的理性认识

区域经济一体化是发展中国家应对经济全球化的一种手段。随着两国经贸往来日益密切,中印建立自由贸易区的条件趋于成熟。建立中印自由贸易区对于促进中印贸易的持续增长、实现两国企业的规模经济、促进两国的经济结构调整以及加强两国政治关系等方面具有积极的意义。因此,两国应该排除困难和障碍,以期早日建立自由贸易区,开创发展中国家之间合作的新局面。     

Surviving in “Localistic Communitas”: Endogenous Multicultural Community Organizing among Migrant Workers in Post-Socialist China

ABSTRACT

Based on 5 months of ethnographic fieldwork and 43 in-depth interviews with villagers of T Township, the author uncovers an emerging approach of endogenous multicultural community practice in the cities where the villagers have migrated to work. Cadres and villagers transplant their localistic networks to the new urban contexts while transforming hierarchical and clientelistic personal ties into more horizontal relations of comradeship. Through these redefined ties, they manage to transcend the persisting boundaries of village units, class status, and lineage institutions that segment the rural society, and succeed in mobilizing community resources to fight for urban survival and social justice. Although neither community service nor the social work profession is fully institutionalized in contemporary China, innovative organizing is appearing in grassroots communities in response to sweeping social changes. This article draws academic attention to these community practices and discusses their implications for the future development of strength-based social work and social services in post-socialist China.     

The Paradox of Integration: Work-Integration Social Enterprises (WISE) and Productivist Welfare Regime in Hong Kong

After the Asian Financial Crisis, the government of Hong Kong embraced the model of work-integration social enterprise (WISE) to sustain its facilitative and productivist welfare regime. Using the WISE of Pro-Love for marginalized women as a case study, the article examines the meaning of employment and social disadvantage in the organization. The ethnographic data reveal that while the WISE encourages women to participate in the paid labor market, it constructs employment in the social enterprise as part-time jobs for supplementary family income, restricts the extension of social networks for the female workers, and reinforces the cultural stereotypes of marginalized women. The study reflects on the mechanisms of the project of WISE in the welfare contexts of Hong Kong, and argues that programs targeted at labor participation cannot be automatically translated into reduction of exclusion in other domains. Long-term planning, policy coordination, and social advocacy are necessary to achieve social integration.
