Sexual agreements and intimate-partner violence among male couples

Objectives: In the United States, HIV continues to disproportionately affect men who have sex with men. One promising area of research that may inform the development of behavioral interventions among male–male couples is within the realm of sexual agreements. Methods: The purpose of our analysis was to determine whether respondents who report having an open agreement or an agreement breakage also report a higher incidence of recent (within the previous 12 months) intimate-partner violence (IPV) compared to respondents who report having a monogamous agreement or no agreement breakage after controlling for demographic variables. Results: Results showed that men who have an open agreement are less likely to report recent physical IPV. Conclusions: The results highlight the need to develop dyadic behavior interventions that address sexual agreements and stress management.     

一种求解双目标线性规划的方法及其在上海市土地使用和交通方面的应用

本文介绍了一种求解双目标线性规划(SBLP)的方法.根据上海市土地使用与交通的现状建立了一个拟动态的模型(BOLT),并用该方法加以求解。根据得到的解对上海市土地使用与交通相互作用的情况进行了分析。     

"乡约"不等于"乡规民约"

长期以来,学者们在研究中经常将“乡约”与“乡规民约”不加区别地混为一谈。事实上,“乡规民约”是基层社会组织的社会成员共同制定出来供大家共同遵守的一种社会行为规范,而“乡约”是乡村社会中以社会教化为主要目的的一种民间基层组织形式,二者的内涵并不相同,其历史发展也遵循着不同的路径。将“乡约”等同于“乡规民约”的研究方法既违背了历史事实,也混淆了两种不同性质的社会文化现象。     

The Evolution of Knowledge and the Dynamics of an Industry Network

The paper moves a step forward in the direction of establishing a connection between the structure and evolution of knowledge bases and the structure and evolution of organizational forms in innovative activities in a science-intensive industry. The paper has an explicit focus on the dynamics of the network of collaborative agreements in R&D in the pharma/biotech industry after the “molecular biology revolution”. Using a comprehensive dataset, built by the authors integrating several sources in the industry, the dynamics of the network over time is extensively analyzed. With regards to network structure, it is found that, while the size of the network increases over time due to net flows of entry, its topological properties remain relatively unchanged. The evolution of the network has occurred without relevant deformations in the core-periphery profile. With regards to age-dependent propensity to collaborate, the paper finds that the extent of inter-generational collaboration is much more significant than intra-generational collaboration. In addition, the propensity of firms of a given generation to enter into collaboration with firms of a different generation increases with the distance between the two, while the total number of intra-generational collaborations decreases over time and, moreover, tends to decrease for most recent generations. In the paper a unitary and coherent explanation of the evidence is developed, coming to reveal the existence of a striking isomorphism between structural properties of the dynamics of knowledge and of the evolution of network structure.

星星之火，何以燎原——论社会保障国际合作的兴起与发展

由于海外劳工在境外就业期间往往会遭遇社会保障双重缺失、社会保障双重缴费以及社会保障待遇支付障碍等诸多困境,使得西欧国家于20世纪初开始探索开展社会保障国际合作,主要方式是国家之间签署社会保障国际协定,合理地承担和分享海外劳工社会保障的责任与效益。经过一个多世纪的发展,社会保障国际合作开始由探索时期步入成熟时期,不仅在覆盖区域、惠及人群以及主要内容方面实现了由小到大、由少到多和由点到面的发展,而且在合作方式上实现了由双边协定到双边与多边协定并举的发展,进而成为了全球各国维护海外劳工社会保障权益的有效途径。     

Multilevel embeddedness: The case of the global fisheries governance complex

This paper explores how bilateral and multilateral clustering are embedded in a multilevel system of interdependent networks. We argue that in complex systems in which bilateral and multilateral relations are themselves interrelated, such as global fisheries governance, embeddedness cannot be reduced to unipartite or bipartite clustering but implicates multilevel closure. We elaborate expectations for ties’ multilevel embeddedness based on network theory and substantive considerations and explore them using a multilevel ERGM. We find states’ bilateral ties are embedded in their shared membership in multilateral fisheries agreements, which is itself clustered around foci represented by similar content and treaty secretariats.     

Policy Space: What,for What,and Where?

This article examines how developing countries can use, and enlarge, existing policy space, without opting out of international commitments. It argues that: (i) a meaningful context for policy space must extend beyond trade policy and include macroeconomic and exchange‐rate policies that will achieve developmental goals more effectively; (ii) policy space depends not only on international rules but also on the impact of international market conditions and policy decisions taken in other countries on the effectiveness of national policy instruments; and (iii) international integration affects policy space through several factors that pull in opposite directions; whether it increases or reduces policy space differs by country and type of integration.     

The coevolution of trade agreements and investment treaties: Some evidence from network analysis

Regional trade agreements (RTAs) and bilateral investment treaties (BITs) are expected to promote trade and investment relationships. One critical feature of such agreements is the network, so the multiplex coevolution of RTAs and BITs should be captured by the dynamics of their two networks. Although many studies have examined the roles of RTAs and BITs, most studies do not account for crucial network properties. This study explores how RTAs and BITs coevolve by applying a stochastic actor-oriented model of multiplex network evolution. In particular, we examine the roles of (i) cross-network dyadic interinfluences and (ii) within- and cross-network preferential attachments to discuss the dynamic relationships between RTAs and BITs. The results are as follows. First, our estimation supports cross-network dyadic interinfluences. Countries that sign a BIT are willing to establish an RTA, while those that sign an RTA are reluctant to establish a BIT. Second, concerning preferential attachments, countries prefer to sign BITs with partners that have more RTA and BIT links. However, countries tend to form RTAs with partners that have more BIT links but are reluctant to form RTAs with those that have more RTA links. We discuss possible justifications for these results, including arguments regarding the benefits and costs associated with the formation of RTAs and BITs.     

WTO中的知识产权协议与中国专利法的修改

WTO中的知识产权协议对中国专利立法和执法都产生了重大的影响,我国于2000年8月25日通过的经第二次修改后的专利法,吸纳和借鉴了WTO中的知识产权协议的有关规定,增加了对专利权人的许诺销售权;对专利的确权实行司法审查;引入了"即发侵权"理论;对"善意使用原则"作了修订,完善了对专利权的保护;明确了专利行政机关的地位,加强了执法力度;对侵犯专利权的赔偿数额做出了较详细的规定,便于司法审判机关实际操作;为及时有效地保护权利人利益,规定了临时保护措施.这些变化,都说明了中国的专利制度已经和国际专利制度基本趋同.     

《海牙排他性法院选择协议公约(草案)》有关知识产权问题的建议

我国对海牙国际私法会议在制订《排他性法院选择协议公约》关于知识产权问题时,应采取以下立场:(1)除版权及其相关的邻接权外,应尽量将其它知识产权权利有效性案件排除在公约的适用范围以外;(2)原则上应将知识产权侵权案件排除在公约的调整范围之外,如果不能排除,则应当限制当事人的选择范围:即只能在侵权行为发生地和被告住所地之间进行选择;(3)对于知识产权合同案件,可以允许当事人选择管辖法院;(4)其它知识产权案件应排除在公约的适用范围之外。
