Work–Family Conflict and Perceived Justice as Mediators of Outcomes of Women's Multiple Workload

Negative impacts of work–family conflicts and the imbalanced division of family work on women's relationship satisfaction and well-being have gained substantial attention from the literature over the last years. The current research adds to the literature by testing the experience of work–family conflicts and perceived justice in the division of family work as possible mediators between women's workloads resulting from the familial and professional tasks and women's relationship satisfaction and well-being. The analysis involves both work-to-family and family-to-work conflicts as well as perceptions of procedural and distributive justice in the division of family work. Structural equation modeling analyses of data were performed with a sample of 1,512 women from dual-earner couples with young children taken from seven European countries. Results support the importance of women's family-to-work conflict and perceptions of justice of childcare and household labor as mediator variables between family workloads, relationship satisfaction, and well-being. Time spent on paid work proved to have an effect on women's well-being, via work-to-family conflict.     

Improved Approximation Algorithms for Maximum Graph Partitioning Problems

We consider the design of approximation algorithms for a number of maximum graph partitioning problems, among others MAX-k-CUT, MAX-k-DENSE-SUBGRAPH, and MAX-k-DIRECTED-UNCUT. We present a new version of the semidefnite relaxation scheme along with a better analysis, extending work of Halperin and Zwick (2002). This leads to an improvement over known approximation factors for such problems. The key to the improvement is the following new technique: It was already observed by Han et al. (2002) that a parameter-driven choice of the random hyperplane can lead to better approximation factors than obtained by Goemans and Williamson (1995). But it remained difficult to find a “good” set of parameters. In this paper, we analyze random hyperplanes depending on several new parameters. We prove that a sub-optimal choice of these parameters can be obtained by the solution of a linear program which leads to the desired improvement of the approximation factors. In this fashion a more systematic analysis of the semidefinite relaxation scheme is obtained.     

Virtual Landscapes of Memory

This paper will focus on two World Wide Web projects: the virtual nation of Cyber- Yugoslavia (www.juga.com) and the homepage of former Yugoslav president Tito (www.titoville.com). Both projects problematize our understanding of nationhood and political leadership through skilful manipulation of the structural characteristics of the medium. The virtual, performative and transitory nature of both the nation and the state will be exemplifed by Cyber-Yugoslavia - a virtual nation- building endeavour conjured up by Belgrade expatriate playwright Zoran Bacic. The changing character of political leadership will be discussed against the backdrop of Tito's homepage, which archives numerous image and sound files documenting the life of the former Yugoslav president. The two projects share at least three common elements: their genre is parody; their subject matter is repressed collective memory; and they reflect the anxieties of the postmodern condition in their treatment of its most emblematic medium, the Internet. The repressed collective memory encapsulated in these projects is that of South-Slav unity, as an alternative to the now dominant particularist ethno-nationalisms of the Yugoslav successor states. The idea of unity of the South Slavs, which gained popularity in the nineteenth century under the Habsburg yoke, was institutionally sanctioned in two twentieth-century Yugoslav states: the Kingdom of Yugoslavia (1918-41), called the Kingdom of Serbs, Croats and Slovenes from 1918 to 1929, and the Socialist Federative Republic of Yugoslavia (1945- 91), called People's Federative Republic of Yugoslavia from 1945 to 1963. The first was made possible by the collapse of the Austro-Hungarian Empire at the end of World War One. Its nation-building rhetoric, underpinning the politics of centralization and Serbian hegemony, rested on a view of Serbs, Croats and Slovenes as "three tribes' of the same nation. The second Yugoslavia, which grew out of the national liberation movement in World War Two, was founded on federalist principles and a nation-building rhetoric of "brotherhood and unity', i.e. national equality for all the member nations. During the period of existence of both Yugoslav states, a tendency against political unification and in favour of the formation of independent national states co-existed with the dominant nation- building narratives. Tito's model in particular, which may be interpreted as a compromise between the two opposing tendencies, left a deep cultural legacy of ethnic tolerance and was internalized by segments of the post-World War Two generations in former Yugoslavia as an important part of their national identity. Linda Hutcheon has explained the popularity of parody in periods of ideological instability as an impulse for challenging the established norms. I would like to suggest that the technological advances and the introduction of the new mass media also encouraged the proliferation of parody as one of the modes of positive self- reference with a universal appeal akin to Bakhtinian "carnival laughter'. The Internet in particular seems to foster the more positive, universalizing aspects of what Hutcheon calls "parodic ethos'.
