Sparse mixture models inspired by ANOVA decompositions. ETNA - Electronic Transactions on Numerical Analysis
No full textInspired by the analysis of variance (ANOVA) decomposition of functions, we propose a Gaussian-uniform mixture model on the high-dimensional torus which relies on the assumption that the function that we wish to approximate can be well explained by limited variable interactions. We consider three model approaches, namely wrapped Gaussians, diagonal wrapped Gaussians, and products of von Mises distributions. The sparsity of the mixture model is ensured by the fact that its summands are products of Gaussian-like density functions acting on low-dimensional spaces and uniform probability densities defined on the remaining directions. To learn such a sparse mixture model from given samples, we propose an objective function consisting of the negative log-likelihood function of the mixture model and a regularizer that penalizes the number of its summands. For minimizing this functional we combine the Expectation Maximization algorithm with a proximal step that takes the regularizer into account. To decide which summands of the mixture model are important, we apply a Kolmogorov-Smirnov test. Numerical examples demonstrate the performance of our approach
The Decision of Whether to Have a Child: Does Couple Disagreement Matter?
No full textMost of the international studies on fertility are based on a female perspective. A majordifficulty in couple-level research is the need for high-quality data that includes informationon both partners. Using couple data from a longitudinal study conducted in Italy [2003-2007],a country with persistently low fertility levels, we examined the effect of disagreement withina couple about childbearing behaviour. The starting point was the hypothesis advanced in anearlier study that Italian women prevail in reproductive decision-making, because childbearinglies mainly in their sphere of influence. The data revealed that the decision rules are parityspecific.At parities zero and one, the disagreement produced an intermediate childbearingoutcome irrespective of which partner wanted a(nother) child; while at higher parities, anasymmetrical veto power model in which the female partner had greater influence wasobserved. The findings suggest that the predictive power of short-term fertility intentionsstrongly improves if both partners’ views are considered in fertility models, and thus supportthe adoption of couple analysis in fertility research

The Urban Transformations of Post-Yugoslavia: Negotiating the Contemporary City in Sarajevo, Belgrade, and Zagreb. Mitteilungen der Österreichischen Geographischen Gesellschaft|Mitteilungen der Österreichischen Geographischen Gesellschaft - Band 162<br/>(Annals of the Austrian Geographical Society - Volume 162)|
No full textThe urban transformations taking place throughout the region of former Yugoslavia are best exemplified in the capitals of the once-communist federation’s successor states. The recent urban developments in the cities of Belgrade, Zagreb, and Sarajevo illustrate the realities of contemporary societies in the Balkans and the socio-political shifts of the period of transition. The built environments of the newly capitalist countries serve as exaggerated, yet emblematic examples of nation-building projects and their deep entwinement with economic processes unfolding throughout post-communist South-Eastern Europe. However, the links between the post-socialist urban and national identity, as well as politics and economy, remain understudied. In this paper, I enquire into the present-day urban transformations of Sarajevo, Belgrade, and Zagreb. I examine these cities within the context of post-Yugoslav economic and political space, exploring the particularities of the creation of built environments that no longer exist on the Yugoslav periphery, but now are at the centre of newly democratic societies. Through the investigation of the political, economic, and architectural particularities of Belgrade Waterfront and Zagreb Manhattan development projects, and Sarajevo City Center commercial complex, I examine the influx of foreign funds – mainly from the Middle East – and their impacts on the construction of regional urban centres. I argue that the modern-day capitals of post-Yugoslav states are developing as products of the interpolation of a communist past into the capitalist present characterised by the perpetual quest for “Europe”, and in line with the broader socio-political and architectural trends in Eastern and South-Eastern Europe. In post-Yugoslavia, urban practices are problematically interwoven with politics: the cities simultaneously serve as displays of geopolitical change and catalysts for social transformation in post-socialist societies
