Multiple partitioning of multiplex signed networks: Application to European parliament votes

For more than a decade, graphs have been used to model the voting behavior taking place in parliaments. However, the methods described in the literature suffer from several limitations. The two main ones are that 1) they rely on some temporal integration of the raw data, which causes some information loss; and/or 2) they identify groups of antagonistic voters, but not the context associated with their occurrence. In this article, we propose a novel method taking advantage of multiplex signed graphs to solve both these issues. It consists in first partitioning separately each layer, before grouping these partitions by similarity. We show the interest of our approach by applying it to a European Parliament dataset.     

对海洋霸权与大陆均势关系的再探讨

虽然以往研究海洋霸权与大陆均势关系的成果颇丰,但还是存在一些不足。为此,本文对海洋霸权与大陆均势关系的结构类型、运行机制及其影响等进行了深化与细化。在海洋霸权国国力大于或小于或等于大陆均势中的有关国家的不同情况下,大陆均势可以分为不需要海洋霸权仅凭大陆国家就能形成的大陆均势和需要海洋霸权且支持其中一方才能形成的大陆均势。不同的国力对比和均势构成情况,对海洋霸权与大陆国家的政治安全与经济发展所产生的影响是不同的。经过分析和比较,本文得出结论:海陆分界难分优劣,关系互补战略呼应,这就是美英极力推行海洋霸权与大陆均势战略的现实诠释。     

Public Debt Sustainability in Africa: Building Resilience and Challenges Ahead

The increased access of African countries to international capital markets has put public debt sustainability at the forefront of the continent's policy agenda. Utilising the ‘stabilising primary‐balance’ approach, this article finds that the actual primary balances exceeded those required to keep public debt at the 2007 level in about half the countries studied, and in several cases, those needed to reduce public debt‐to‐GDP to sustainable thresholds. The interest rate‐growth differential (IRGD) drove sustainability, underscoring the importance of growth and borrowing for growth‐enhancing outlays. As the IRGDs are likely to narrow over the longer term, fiscal policies will need to play a greater role.     

曲柄群驱动机构单元化平衡

为实现曲柄群驱动机构的模块化设计与生产，定义曲柄单元为该机构的基本单元，以曲柄单元为基础研究曲柄 群驱动机构模块化设计中的摆动力平衡问题。研究了影响平衡块质量及配置位置的因素。分析表明，当在所有曲柄的 反方向配置参数相同的平衡决时，平衡决的质量矩与机构中的曲柄个数，曲柄的质量与长度，运动连杆总质量有关。得 出一种满足模块化设计与生产的方法，该方法能快速有效地实现曲柄群驱动机构单元化平衡     

Stretching the borders: how international business travel affects the work–family balance

This study examined the consequences of international business travel for the balance between work–family domains by exploring how international business travellers and travellers’ partners manage the boundaries between work and family in order to maintain the balance. Interpretative phenomenological analysis was used in analysing the semi-structured interviews of 10 male travellers and 10 partners. Because of its irregular nature, international business travel affects the personal life and the family of business travellers. Work-related travel also has an impact on how travellers and their partners construct, manage and negotiate borders between work and family in order to avoid an imbalance between these domains. Integration of work and family is usually inevitable in international business traveler families. Integration may lead to role blurring and thus lead to imbalance.     

Life Balance and Work Addiction Among NCAA Administrators and Coaches

Intercollegiate athletics represent an industry prone to challenges of work addiction and life balance. Work addiction and life balance domains in male and female intercollegiate athletic coaches and administrators (N = 245) were examined using multiple regression analysis. Higher levels of stress/anxiety, sleep disturbance, and career satisfaction and lower levels of quality of relationships and friendships were the strongest predictors of work addiction. Counseling focused on reducing the negative aspects of work addiction, while maintaining job performance, may benefit this population.     

Spatially Balanced Sampling of Continuous Populations

When sampling from a continuous population (or distribution), we often want a rather small sample due to some cost attached to processing the sample or to collecting information in the field. Moreover, a probability sample that allows for design‐based statistical inference is often desired. Given these requirements, we want to reduce the sampling variance of the Horvitz–Thompson estimator as much as possible. To achieve this, we introduce different approaches to using the local pivotal method for selecting well‐spread samples from multidimensional continuous populations. The results of a simulation study clearly indicate that we succeed in selecting spatially balanced samples and improve the efficiency of the Horvitz–Thompson estimator.     

Recent developments in D-optimal designs

In the paper, some issues concerned with the determining spring balance weighing designs satisfying the criterion of D-optimality under the assumption measurement errors are uncorrelated and they have the same variances are discussed. In addition, highly D-efficient spring balance weighing designs are also considered. Some conditions under which any spring balance weighing design is regular D-optimal or highly D-efficient are proved. What is more, new construction methods of regular D-optimal and highly D-efficient spring balance weighing designs are presented.     

权利效能视角下的非法证据排除

非法证据排除的权利效能是辩方排除非法证据的实际效果与法律授予的理想权利之间的比值。非法证据排除规则赋予了辩方较大的权利,并随着诉讼进程而增强。但实际所取得的效益却是逐程减弱,并最终在庭审阶段降至权利效能的最低点。这种尴尬局面是由法律、制度以及辩护策略等原因造成。从诉讼结构出发去研究权利效能,对于完善该制度具有功能意义,应从保证控辩双方效能值的全程一致、限制法官自由裁量权与完善辩方权利行使机制三个方面着手构建。
