Strukturwandel sozialpolitischer Steuerung?

This article focuses, from the vantage point of modernization theory, on the reforms of the Code of Social Law II (Sozialgesetzbuch II) in Germany. Its argumentation is based on the historico-genetic theory. The argument is that the reforms of SGB II in the year 2005 implement a structural change within social policy that is based on the loss of autonomy of its subjects and reproduce the “theoreme of the poverty trap” (Armutsfallentheorem), which has already been refuted empirically. The new dimension of social policy lies in a downsizing of autonomy based on a cut of planning horizons and of individual rights as well as on a reinforced connection of employment and food. The possibility of autonomous action gets lost. That means that the constitutive condition of social policy, the idea that people shape their own lives, is undermined and social policy is regressing behind the functional achievements of modernity. The argumentation is based on a semantic analysis of the reforms within two functional systems of society, law and politics.     

Going Back Home? Changing Demography and Geography of Mexican Return Migration

Return migration has been a constant feature of Mexico?CUS migration patterns, but its characteristics have changed sharply with time. We use the Mexican censuses and counts of 1995, 2000, 2010, and the complete set of individual and household records of the 2005 Population Count to explore the demographic characteristics of returnees in the context of tighter border control and rising levels of forced return migration. Involuntary and therefore unplanned return is likely to mean greater difficulties of incorporation into the community of origin. The study of the effects of the militarization of the US?CMexico border on migration patterns has focused on the US side. We contribute to this literature by focusing on the Mexican side. We consider the intensity and type of previous migration to the US as compared to current return migration, and State of origin and destination. Our data suggest that particularly attractive destinations for returnees are border cities, prosperous communities and growing metropolitan areas. Findings suggest changes in the demographic composition and geographic distribution of returnees. The discordance between the patterns of outmigration and return is a telling indicator of changes in the overall migration relationship between Mexico and the US. The patterns for 2005 are also observed in 2010 even if the absolute number of inter-censal returnees increased threefold over the period. Finally, we argue that focusing on destinations of return instead of areas of emigration will contribute to a more comprehensive understanding on the nature of future return migration to Mexico and its policy implications.     

Do Immigrants Compete with Natives?

The paper analyses the impact of foreign workers on the Italian labour market. We address the issue of whether immigrants from less developed countries are complementary or substitutes to domestic workers. We construct a data set on immigrant workers from the Administrative Social Security Archive which starts in 1986, before the general amnesty of 1990–91, when a large share of illegal immigrants were granted working permits, and end in 1995. A two-stage procedure devised by Moulton is applied to yearly cross-sections of wages by industry and region. Our results show that the inflow of immigrants raises the wages of native manual workers (i.e. it has a complementary effect), and this effect is larger in small firms and in the north of the country. We postulate that the positive impact on native wages is due to the existence of labour constraints on the side of firms. Firms are unable to expand their output because they cannot find native workers who are willing to undertake certain (typically low-skilled) jobs. Immigrants help to fill this gap. This view is reinforced by the fact that over a ‘crucial threshold’ of the share of foreign work (7.7–12 percent) additional inflows in the labour market of foreign work have a negative effect on native wages (i.e. they compete with natives).     

The Role of Social Infrastructure in Achieving Inclusive Liveable Communities: Voices from Regional Australia

What makes liveable communities inclusive is an important question for planning research, policy and practice, yet one that has not received significant attention. This article explores this question through the lived experiences of two spatially marginalised groups – people with disabilities and seniors. Using the photovoice technique, the findings visually and textually demonstrate the importance of universally accessible social infrastructure in enabling inclusion and active participation in a community in regional Australia. The findings suggest that inclusion should be a central focus of liveability, along with co-design processes with people experiencing spatial marginalisation to achieve inclusive liveable communities.     

Somebody has to DUST! Gender,health, and housework in older couples

This study examines the link between health and housework among older couples. For those out of the paid labor force, many of the standard arguments about relative resources and time availability no longer hold. Women spend more time on domestic tasks than men at any age; however, it is unclear how health shapes the household division of labor based on gender among older adults. This study examines the relative effect of three dimensions of health. Women’s poor health increases the chance of an equal division of labor, but the gender nature of household tasks may limit women’s ability to cut back.     

Uncertainty,Doubts, and Delays: Economic Circumstances and Childbearing Expectations Among Emerging Adults

Fertility, or childbearing, expectations have been increasingly identified as an important area of research, at least in part because expectations may help us to understand family issues of concern across the globe such as unintended pregnancies, low fertility, and delayed childbearing. While much research has focused on the link between expectations and behavior, this study extends the literature by asking how those expectations were shaped initially. Specifically, we explore how one’s economic context is related to expectations. This paper further extends the literature by focusing on two dimensions of the parenthood expectations of young people (men and women aged 18–27). Using the 2005, 2007, 2009, and 2011 waves of the Panel Studies of Income Dynamics (PSID) Transition to Adulthood (TA) sample, we considered whether young people expected to have children in the future and, for those who did, when they expected to do so. The results support financial-strain theories of the relationship between (subjective and objective) economic circumstances and childbearing expectations. Women and men with lower earnings, less education, and more worries about their future job prospects are more uncertain whether they will have children. Of those who expect to have children, those with more education and more worries expect to do so later in life. Further analyses reveal that race and gender condition these relationships.     

Birds biodiversity in urban and periurban forests: environmental determinants at local and landscape scales

A significant decline in biodiversity is associated with the current and upcoming degree of urbanization. A challenging strategy to address this conflict is to make urban growth compatible with biodiversity protection and in this context urban parks can play a crucial role. Urban systems are highly dynamic and complex human-shaped ecosystems, where the relationship between species and environment may be altered and make the preservation of biodiversity within them a challenging goal. In this study, we analysed how different environmental features affect bird biodiversity in one of the most urbanized areas of Italy (the metropolitan area of Milan) at different spatial scales. Bird surveys were conducted in fifteen urban and peri-urban parks and environmental variables at landscape and local scale recorded. Results showed that a mixture of land covers and the presence of water bodies inside urban parks favoured species occurrence and abundance at landscape scale, but a surrounding dense urban matrix deflated biodiversity. At local scale, woodland cover and presence of water bodies were key determinants in ensuring overall high biodiversity but local-specific vegetation management produced an unusual pattern for forests species. In particular, the maintenance of large trees may not result in biodiversity support for forest bird species if large trees are not located in woodland areas with a significant tree density. To understand biodiversity patterns and provide useful information for urban planning and design, we need to provide insights into species/environment relationships at multiple scales in the urban environment.     

Examination and visualisation of the simplifying assumption for vine copulas in three dimensions

Vine copulas are a highly flexible class of dependence models, which are based on the decomposition of the density into bivariate building blocks. For applications one usually makes the simplifying assumption that copulas of conditional distributions are independent of the variables on which they are conditioned. However this assumption has been criticised for being too restrictive. We examine both simplified and non‐simplified vine copulas in three dimensions and investigate conceptual differences. We show and compare contour surfaces of three‐dimensional vine copula models, which prove to be much more informative than the contour lines of the bivariate marginals. Our investigation shows that non‐simplified vine copulas can exhibit arbitrarily irregular shapes, whereas simplified vine copulas appear to be smooth extrapolations of their bivariate margins to three dimensions. In addition to a variety of constructed examples, we also investigate a three‐dimensional subset of the well‐known uranium data set and visually detect the fact that a non‐simplified vine copula is necessary to capture its complex dependence structure.
