Relational Equity as a Design Tool Within Making and Tinkering Activities

This article focuses on the partner-like relations that emerge between undergraduates and youth as they engage in “Making and Tinkering” activities in an afterschool learning ecology, and illustrates the potential for designed tinkering activity to produce relational equity among participants. Grounded in sociocultural theory, but leveraging theoretical contributions from learning sciences and tinkering research, we draw on ethnographic data across one year to examine how the social organization of Making & Tinkering activities provides necessary social conditions for “feedback-in-practice” and consequential learning. Analyses of interactions reveal how more symmetrical intergenerational relationships serve in the design of equitable learning spaces.     

Resolving an Insurance Allocation Problem: A Procedural Approach

In this paper we study the problem of the determination of a fair allocation in a co-insurance problem, i.e., how some insurance companies have to share the risk and the premium. We develop two procedures that produce a proportional and an equitable allocation, respectively. The procedures are applied to a real situation arising from environmental risk and the resulting allocations are compared with the classical quota share allocation and with an envy-free allocation resulting from a procedure presented in Fragnelli and Marina (Insur. Math Econ 33:75–85, 2003).     

Familienpolitik, Bildung und Berufskarrieren von M��ttern in Deutschland, USA und Schweden

This article compares the duration of and consequences for employment interruptions for mothers with distinct educational qualifications in cross-national perspective. We analyze the duration of mothers?? employment interruption and the relative quality of the job after childbirth, for high and low qualified mothers in Germany, Sweden, and the United States. Analyses are based on harmonized national longitudinal data sets (GLHS-West, NLSY, LNU), which allow us to study mothers?? careers over the past 30?C35 years. We apply event-history analysis to study how long mothers with distinct educational levels interrupt employment after childbirth, and how the patterns of return to work differ with respect to mothers?? educational level. In all three countries the highly educated display a greater labor market attachment. In the US, almost half of the mothers with some college background, compared to only a quarter of high-school dropouts stay employed continuously after childbirth. In Sweden, basically all mothers take time-out for at least half a year. In Germany, 25% of mothers with university entrance qualification do not claim parental leave. In Germany and Sweden consequences of leave extensions seem to operate independent of mothers?? educational levels. In the U.S. medium and highly educated mothers tend to return more slowly after the enactment of the FMLA.     

Anonymous and neutral majority rules

In the standard arrovian framework and under the assumption that individual preferences and social outcomes are linear orders on the set of alternatives, we provide necessary and sufficient conditions for the existence of anonymous and neutral rules and for the existence of anonymous and neutral majority rules. We also determine a general method for constructing and counting these rules and we explicitly apply it to some simple cases.     

International Well-being Index: The Austrian Version

The International Well-being Index (IWI) measures both personal and national well-being. It comprises two subscales: the Personal Well-being Index (PWI) and the National Well-being Index (NWI). The aim of this paper is to test the psychometric properties (validity and reliability) of the translated scale in Austria. Convergent validity is assessed using the Scales of Psychological Well-Being, the Satisfaction with Life Scale and the Positive and Negative Affect Scale. In addition, a Visual–Analog Scales capturing “satisfaction with life as a whole” was applied. The participants were 581 students of the Medical University Innsbruck (female: 47.7%; age: 23.2 ± 3.7). Internal consistency (Cronbach’s α) of the IWI was for both scales > .70 (PWI: .85; NWI: .83). The exploratory factor analysis of the IWI identified a 2-factor-structure identical with the two scales of the IWI explaining 54.2% of the variance. The convergent validity hypotheses were confirmed, construct validity was partly confirmed for the PWI being a deconstruction of a first factor called “satisfaction with life” (38.1% explained variance). Happy participants scored higher on the PWI (84.3 ± 7.9 vs. 68.7 ± 13.7; p < .001) and NWI (64.3 ±  15.8 vs. 57.9 ±  15.1; p < .001) scores than unhappy participants. It is concluded that the Austrian version of the IWI is a reliable and valid instrument to assess personal and national well-being. Further studies including a representative sample should be carried out on a recurring basis to use the IWI as an indicator for social science research in Austria.

The impact of international migration on the public pension system: The case of Portugal

This article analyses the impact of replacement migration on the financial sustainability of the old‐age pension system in Portugal, a country with one of the largest ageing populations in Europe. We do this using demographic forecasts and prospective exercises for the evolution of the Portuguese economy. During the 2015–2060 period, our results evidence the positive impacts of international migration on old‐age pension system financial balances, reaching over 3 per cent of GDP after 2045. Moreover, even when taking into considering the low dynamics for the Portuguese economy, replacement migration is an important input to improve pension system financial sustainability.
