The aim of the article was to characterize the structure of scientific collaboration launched by Polish institutions in partnership with foreign entities in 2019 with a special focus on the territorial context. An analysis of the network generated on the basis of data from the POL-on system was made: weak components, the degree centrality and the betweenness centrality for each entity were identified, as well as significant connections in the network reduced to the level of countries and to voivodeships. A key entity in the network was indicated (the Central Mining Institute). Some foreign entities show high betweenness centrality in the considered network. At the level of relations between countries, the high network density and significant activity of institutions from Germany were observed, which in the future may hinder gaining advantages. Scientific collaboration of Polish institutions is carried out mainly with centres located in Europe, but it is generally not cross-border.

This article opens with a review of the main trends in family-related behaviour, i.e. fertility decline and changes in fertility patterns, a decreasing propensity to marry, postponement of marriage, and a slowly increasing frequency of divorces and separations. The analysis takes into account urban and rural differences. We then aim to identify the main determinants of family changes within the general conceptual framework of the Second Democratic Transition (SDT) in Poland. However, contrary to mainstream interpretations of the SDT, the main emphasis of this study is on the structural components of change, which need to be reformulated to account for processes specific to the transition to a market economy. The focus is, therefore, on labour market developments and family policy, and to a lesser extent on ideational change.

'This article uses data from the European Union Labour Force Survey (EULFS) 2004 for a comparative analysis of individual and contextual determinants of temporary employment contracts in Central and Eastern European (CEE) countries. Descriptive analyses reveal that temporary contracts are more often involuntary by nature and associated with relatively lower occupational status than permanent contracts in CEE countries compared to Western European average. Individual-level logistic regressions show that the general determinants of temporary employment are rather similar in both parts of Europe, but vary in their strength between countries. To evaluate the impact of macro-level influences on these cross-country differences in temporary employment risks, we focus on the risk of young people as one group of potential labour market outsiders. In general, young persons have a higher temporary employment risk, but their relative risk varies between countries. We use multi-level models implemented in a two-step estimation procedure and try to explain this cross-country variation with the intervening role of institutional influences under control of macro-structural conditions. Comparing CEE countries and Western European countries shows that neither employment protection of regular contracts nor its interaction with the level of employment protection of temporary contracts affects the young people's risk. Instead, we find a positive association between collective bargaining coverage as a measure of insider-outsider cleavages and the relative temporary employment risk of young persons.'
