重振布隆方丹中央商务区：前景、阻碍与错失的机会

一个多世纪以来,人们对城市变迁展开了系统性的研究,其中一个焦点是城市的中央商务区（CBDs）。过去几十年里有大量关于中央商务区衰落问题的文献,焦点集中在这种衰退为什么会发生,以及可以出台哪些刺激性政策措施来重振这些地区。本文主要讨论大城市中较为发达的地区,从地理上说就是南非北部的前工业重镇。就这些问题南非的学者也有为数不多但值得我们重视的文献,他们以年鉴形式记录了中央商务区的衰落及后续的重振措施。与国际上的经验类似,研究的焦点集中在南非的主要大城市地区,而二线城市则不在研究者们关注的范围之内。本文概述二线城市布隆方丹的中央商务区重振所面临的前景和阻碍的目的是,尽管在开普敦和约翰内斯堡等城市开展一般性的重振项目对抑制中央商务区的进一步衰退有显著成效,但对布隆方丹这样的二线城市来说,可能还需要一些其他措施。     

Historical legacies, nationalist mobilization, and political outcomes in Russia and Serbia: A Weberian view

Conclusion In the preceding analysis, I attempt to demonstrate the usefulness of some of Weber's key theoretical ideas on nations, nationalism, and imperialism by way of a comparative examination of contemporary Russian and Serbian nationalism. More specifically, I try to show how long-term historical and institutional legacies, shared memories, and defining political experiences, played themselves out in the contemporary period, influencing the different availability of mass constituencies in Russia and Serbia for nationalist mobilization under the auspices of new empire-saving coalitions.But political outcomes are never wholly pre-determined as historical legacies are subject to different cultural interpretations and political contest. To put it simply, nationalism is made and remade by politicians and ideologists; and there is no need to gloss over the frequently bloody and unpredictable consequences of their struggles with unduly abstract sociological generalizations. Instead, we should theorize our narratives, while giving contingency its place.I suggest that the presence of a highly symbolic issue (such as the World War Two experiences of Serbs in Croatia, the mythology of Kosovo, Sevastopol or the mythology of the Russian fleet), which touches on the core historical mythology of one nation, but is contested by another on different grounds (demographic, ethnic, or for reasons of historical justice, for example) increases the likelihood of national conflicts. Once highly symbolic issues are involved, national conflicts quickly assume the form of struggles over ultimate values not subject to compromise and conflict-regulation. However, as the Russian case demonstrates, other symbolic legacies (the experience of Stalinism) might be powerful enough to override nationalism.I also suggest in this article a few simple ways in which we can interpret, and possibly, test the likelihood of the emergency of national conflicts: the significance of prestige considerations, the absence of compensatory mechanisms such as economic prosperity, the egalitarian character of nationalist appeals, the dynamic of status-reversal, and the theory of the superimposition of conflicts. To understand the exclusivist overtones of much of contemporary nationalism in the former Soviet Union and Eastern Europe, however, it would also be necessary to pay more attention to the political-cultural and social-structural legacy of Communist rule. The prevalence of uncompromising stances among political leaders, the absence of mechanisms of conflict-regulation, the hostility to proceduralism and legal mechanisms as a means of resolving the emerging national questions, and the appeal of the new nationalism to state-dependent and traditionalist strata are among the most important elements of this legacy.     

Broadcasting multiple messages in the 1-in port model in optimal time

In the 1-in port model, every vertex of a synchronous network can receive at most one message in each time unit. We consider simultaneous broadcasting of multiple messages from the same source or from distinct sources in such networks with an additional restriction that every received message can be sent out to neighbors only in the next time unit and never to already informed vertex. We use a general concept of level-disjoint partitions developed for this scenario. Here we introduce a subgraph extension technique for efficient spreading information within this concept. Surprisingly, this approach with so called biwheels leads to simultaneous broadcasting of optimal number of messages on a wide class of graphs in optimal time. In particular, we provide tight results for bipartite tori, meshes, hypercubes, Knödel graphs, circulant graphs. We also propose several open problems and conjectures.     

Generalized blockmodeling of valued networks

The paper presents several approaches to generalized blockmodeling of valued networks, where values of the ties are assumed to be measured on at least interval scale. The first approach is a straightforward generalization of the generalized blockmodeling of binary networks [Doreian, P., Batagelj, V., Ferligoj, A., 2005. Generalized Blockmodeling. Cambridge University Press, New York.] to valued blockmodeling. The second approach is homogeneity blockmodeling. The basic idea of homogeneity blockmodeling is that the inconsistency of an empirical block with its ideal block can be measured by within block variability of appropriate values. New ideal blocks appropriate for blockmodeling of valued networks are presented together with definitions of their block inconsistencies.     

Facilitating labour migration from Latvia: strategies of various categories of intermediaries

ABSTRACT

Within the broad category of migration industries, we focus on intermediaries between employers in Norway requiring migrant labour, and suppliers of Latvian workers willing to migrate. Mediation of labour power is a regulated domain in both countries, but regulations may change: regulations in Latvia have become more lenient, whereas in Norway, they have become stricter in response to increased migration. Intermediaries must be responsive to fluctuations in labour supply and demand, as well as to changing regulations. Today, destination countries are experiencing an overabundance of available migrant labour. This buyer’s labour market represents a challenge for intermediaries, spurring adjustments and side-stepping of regulations. Formal temp agencies are supplemented by informal ones, challenging the conceptualisation of intermediaries. Also work migrants may become agents, shaping new forms of intermediation and expanding the concept of ‘migration industry’ to encompass facilitation of labour migration through social networks. In this article, we construct typologies inductively, establishing categories meaningful in the complex context of labour migration from Latvia to Norway. We distinguish between mediation through formal versus informal agencies, establish characteristics of agencies versus individual social network-based mediation and discuss mediation through the posting of workers by companies.     

The Quest for Government Accountability and Rule of Law: Conflicting Strategies of State and Civil Society in Cambodia and Serbia

This article deals with the social accountability activities of civil society organizations in Serbia and Cambodia. In both countries, they emerged with the conceptual and financial support of international development agencies; yet, the outputs were mediated by the social and political contexts. Still, these activities have some joint features: they (1) boost both understanding and awareness rather than solely mobilizing social interests; (2) target the interests of individual citizens rather than the interests of social-based groups or classes; (3) promote state cooperation instead of confrontation and (3) insist on the use of technical policy-related tools and mechanisms instead of political mobilization. The social accountability initiatives analyzed here have followed a policy-not-politics or depoliticized approach. As a consequence, they were ineffective in mobilizing citizens and social groups in a manner that would efficiently demand more accountability. On the other hand, governments contested civil society and appropriated its accountability discourses and strategies in an effort that can be read as an attempt to resist imposing government accountability and rule of law and pacifying present and future civic activism.     

Elements of life satisfaction among young adults in Serbia

Contemporary sociological studies argue that employment and personal life have diversified effects as determinants of life satisfaction (LS) of young adults. We have, therefore, decided to explore the three different aspects of general LS, satisfaction with personal (intimate) domain, satisfaction with family life and satisfaction with occupation (professional domain), by using the survey data on 1627 young adults aged from 19 to 35 from Serbia. The correlations between the three domains are significant, while the strongest tie is between satisfaction with intimate relations and satisfaction with family life. The analysis exposed that social variables (employment, education, housing autonomy and financial autonomy) and personal variables (partnership and parenthood) are in a diverse manner related to the three domains of LS, as well as that their effects are different for young men and women. Taking into account particularities of social context in Serbia, we have introduced functional autonomy (decision-making and acting independent of parents) as mediating variable. The results uncover that functional autonomy has little influence on satisfaction with occupation, while social variables have a strong effect, suggesting that agency in professional domain is significantly socially bound. Regression models reveal divergent and gender-specific relations of variables and three aspects of LS related to particular structural and cultural context in Serbia that sets limits to gender detraditionalization.     

Diathesis stress or differential susceptibility? testing longitudinal associations between parenting,temperament, and children's problem behavior

In this study we investigated longitudinal associations among parenting, children's temperamental negative affectivity, and internalizing and externalizing behavior. Second, we tested whether findings confirmed the diathesis‐stress model or differential susceptibility theory when conducting stringent interaction tests. The sample included 129 children and their families. Parenting quality (age 5) was measured by parent–child interaction observations. Parents evaluated child negative affectivity (age 7) and teachers reported on problem behavior (age 12). Multiple regression analyses revealed an interaction effect of negative affectivity and parenting on externalizing behavior. Visual inspection suggested ‘for better and for worse’ effects of parenting for children with negative affectivity. However, more stringent tests failed to show convincing evidence for differential susceptibility theory. For internalizing behavior, negative affectivity may render children vulnerable regardless of parenting. Our results point at the importance of further testing interaction effects to distinguish between differential susceptibility theory and the diathesis‐stress model.
