Trading in development: norms and institutions in the making/unmaking of European Union–African,Caribbean and Pacific trade and development cooperation

This paper offers a contribution to recent debates on European Union (EU) external trade and development policy, with a specific focus on the African, Caribbean and Pacific (ACP) group of countries. The question asked is why the EU encountered such difficulties in the attempt to translate its normative preferences for freer trade and closer economic integration into a series of binding agreements? Drawing on both economic constructivist and historical institutionalist insights, it is argued that the case for reform initially rested on a strong convergence between institutions and ideas, enabling the EU to discursively present desired policy reforms as necessary to satisfy World Trade Organisation trade rules. However, in due course, the institutional dynamics behind the latter began to diverge from the EU's policy preferences and blunt its norm-based argument – thus creating the space for transnational coalitions to, first, question and, ultimately, undermine aspects the EU's trade and development prospectus for the ACP.     

差异公民资格与正义:艾利斯·马瑞恩·杨政治哲学探微

在当代西方女性主义政治哲学中,艾利斯·马瑞恩·杨以其"差异的公民资格"与"差异政治"而独具特色.从对罗尔斯为代表的自由主义普遍公民资格的批判出发,她说明了自由主义普遍公民资格如何忽略或至少是回避了差异及差异群体的权利要求.她以差异的公民资格为切入点,揭示出女性主义政治哲学之差异正义的根本理论诉求,这不仅为女性等差异性群体争取自身权利指明了方向,也试图以另外一种新的视角,即公民资格的理论视角,冲击传统意义上普遍主义的正义理解.在当代多元文化的广阔背景下,差异的公民资格和差异平等的正义观照正越来越成为差异性群体争取自身权利的理论武器,而差异正义的独特理论诉求也正日益成为普遍正义的一种有意义的补充.

重物落水后运动过程的数学模型

为更好描述重物落水后的运动过程,设计了模拟封堵溃口小型试验,首先对重物落水后运动过程的影响因素进行分析,对采集的试验数据进行了分类处理,并对典型的试验数据进行比较分析,突出主要影响因素.其次对水中的重物进行了受力分析,以大实心方体为例,初步建立重物在水中运动过程的二阶微分方程模型（模型1）,结合步长搜索法和最小二乘法确定压差阻力系数的初始范围,然后在Matlab平台下做非线性最小二乘拟合求解运动模型中压差阻力系数kx、ky;在模型1的基础上引入速度后损率kv,完善了重物在水中运动过程的二阶微分方程模型（模型2）,并对模型中2的参数进行求解.模型结果验证显示,引入速度后损率后的模型2能比较好地反映重物落水后的运动过程,并对以后的研究提供了参考.     

萨瑟兰的不同交往理论及其启示

不同交往理论是美国著名犯罪学家萨瑟兰解释犯罪的一个重要理论,它在美国犯罪学研究史上曾大放异彩。从萨瑟兰的不同交往理论的9个命题出发,并结合我国国情,由此可得到对于我国立法、青少年犯罪预防及犯罪分子改造的有益启示;而以我国传统文化为基点,则该理论对我国的现实价值有更深刻的认识。

Influence of Family,Agency, and Caseworker Dynamics on Caregivers' Satisfaction With Their Child Protective Services Experience

Numerous child protective services (CPS) agencies have adopted differential responses as a system reform hypothesized to facilitate family engagement. This research tests a conceptual framework developed to examine dynamics between caregiver, agency, and caseworker factors that are assumed to impact caregiver engagement. Data from a randomized control study and structural equation modeling methods were used to explore the influence of these factors on caregiver satisfaction with their CPS experience. The results indicate that receipt of alternative response, caregivers' ratings of their caseworker's interaction style, and caregivers' positive emotional response influenced satisfaction with their intervention experience, while negative emotional responses did not.     

Color Separation in Forensic Image Processing Using Interactive Differential Evolution

Color separation is an image processing technique that has often been used in forensic applications to differentiate among variant colors and to remove unwanted image interference. This process can reveal important information such as covered text or fingerprints in forensic investigation procedures. However, several limitations prevent users from selecting the appropriate parameters pertaining to the desired and undesired colors. This study proposes the hybridization of an interactive differential evolution (IDE) and a color separation technique that no longer requires users to guess required control parameters. The IDE algorithm optimizes these parameters in an interactive manner by utilizing human visual judgment to uncover desired objects. A comprehensive experimental verification has been conducted on various sample test images, including heavily obscured texts, texts with subtle color variations, and fingerprint smudges. The advantage of IDE is apparent as it effectively optimizes the color separation parameters at a level indiscernible to the naked eyes.     

Peer pressure and adolescent substance use

Peer influence is regarded as one of the strongest determinants of juvenile delinquency and particularly adolescent substance use. A commonly held view is that social pressure from friends to use drugs and alcohol is a major contributor to substance use. Yet the notion of peer pressure, implied by the association between peer-group associations and drug behavior, is seldom tested empirically. As a crucial test of the group pressure model, this research examines the role of peer pressure in mediating the effect of differential association on individual use. Moreover, few studies examine the nature of the relationship between peers and substance use as it relates to the processes leading toand from use. Drawing on differential association and social learning theories, our research specifies the social processes (socialization, group pressure, social selection, and rationalization) which dictate particular causal pathways leading to and from substance use and then estimates the reciprocal influences among differential association, social pressure from peers, attitudes favorable toward substance use, and individual use. Using the 1977–1979 National Youth Survey panel data, we estimate a covariance structural equation model allowing for correlated measurement error. In the cross-sectional analyses, we find no main effects of overt peer pressure on substance use. Estimation of the reciprocal effects model also reveals that overt peer pressure does not significantly influence substance use and does not mediate the effect of differential association. Instead, the influences of socialization, social selection, and rationalization play significant roles in understanding substance use.An earlier version of this paper was presented at the 1994 American Society of Criminology meetings in Miami, Florida.
