Stable sets and cores for multi-criteria simple games and for their extensions

In this article we deal with multi-criteria simple games which constitute an extension of the basic framework of voting systems and related social-choice situations. We generalize two closely related solution concepts for these games, the stable sets and the core. A relationship between stable sets and minimal winning coalitions is established. Two generalizations of the core for multi-criteria simple games are characterized in terms of veto players. In addition, extended multi-criteria simple games obtained from different aggregation operations, such as union, intersection, marginalization, and composition, are introduced. It is shown that a voting system can be established when these operations are applied to complex voting systems.     

Quantitative Risk Analysis on the Transport of Dangerous Goods Through a Bi‐Directional Road Tunnel

A quantitative risk analysis (QRA) regarding dangerous goods vehicles (DGVs) running through road tunnels was set up. Peak hourly traffic volumes (VHP), percentage of heavy goods vehicles (HGVs), and failure of the emergency ventilation system were investigated in order to assess their impact on the risk level. The risk associated with an alternative route running completely in the open air and passing through a highly populated urban area was also evaluated. The results in terms of social risk, as F/N curves, show an increased risk level with an increase the VHP, the percentage of HGVs, and a failure of the emergency ventilation system. The risk curves of the tunnel investigated were found to lie both above and below those of the alternative route running in the open air depending on the type of dangerous goods transported. In particular, risk was found to be greater in the tunnel for two fire scenarios (no explosion). In contrast, the risk level for the exposed population was found to be greater for the alternative route in three possible accident scenarios associated with explosions and toxic releases. Therefore, one should be wary before stating that for the transport of dangerous products an itinerary running completely in the open air might be used if the latter passes through a populated area. The QRA may help decisionmakers both to implement additional safety measures and to understand whether to allow, forbid, or limit circulation of DGVs.     

End-of-Life Preparations among Lesbian,Gay, Bisexual,and Transgender People: Integrative Review of Prevalent Behaviors

Proactively making end-of-life (EOL) preparations is important to ensure high quality EOL care. Critical to preparation is the discussion of preferences with one’s primary health care providers. Lesbian, gay, bisexual, and transgender (LGBT) people often experience discrimination from health care providers that will detrimentally affect their ability to communicate their care preferences. Structural barriers, such as those based on sexual orientation and gender identity, may impede timely and quality care when one is most in need. The aim of this study was to examine the prevalence of EOL preparatory behaviors among LGBT people, with particular focus on transgender individuals. Eight survey instruments with 30 prevalence estimates found in the literature were analyzed. EOL discussions between LGBT people and their primary health care providers were rare (10%). Transgender people were found to be even less prepared for EOL; they were 50–70% less likely than their LGB counterparts to have a will, a living will or to have appointed a healthcare proxy. A need exists for future mixed-methods research focused on LGBT populations accompanied by the cultural sensitivity needed to ensure their wishes are honored at the EOL.

The National Work–Life Balance Index©: The European Case

More than 5 years since the outbreak of the global financial crisis, a flurry of evidence is emerging on the effects of the ensuing economic downturn on unemployment and poverty rates in rich countries, but less is known about cross-country differences in subjective assessments of the crisis and whether adults in households with children were affected to a greater extent. This paper investigates differences in the perceived impact of the economic crisis between adults in households with and without children in 17 European countries, using data from the Life in Transition Survey 2010 in a multilevel modelling framework. It also explores differences in the coping strategies that households adopted to deal with the decline in income or economic activity. Everything else being equal, perceptions of the crisis were more widespread in countries with higher rates of child poverty, lower economic growth and lower GDP per capita. Across countries, perceptions of the crisis closely trailed subjective indicators of financial difficulties from other international surveys conducted in 2010. Adults in households with children were more likely to report an impact of the crisis, with larger differences in countries with higher rates of monetary child poverty. Adults in households with children also adopted a greater variety of coping strategies than the rest, prioritizing expenditure on basic necessities, while cutting back on luxuries and holidays. Nevertheless, many still reported reduced consumption of staple foods as a result of economic difficulties.     

Turning the Immigration Policy Paradox Upside Down? Populist Liberalism and Discursive Gaps in South America

A paradox of officially rejecting but covertly accepting irregular migrants has long been identified in the immigration policies of Western immigrant receiving states. In South America, on the other hand, a liberal discourse of universally welcoming all immigrants, irrespective of their origin and migratory status, has replaced the formally restrictive, securitized and not seldomly ethnically selective immigration rhetoric. This discursive liberalization has found partial translation into immigration laws and policies, but contrary to the universality of rights claimed in their discourses, governments reject recently increasing irregular south–south migration from Africa, Asia, and the Caribbean to varying degrees. This paper applies a mixed methodological approach of discourse and legal analysis and process tracing to explore in how far recent immigration policies in South America constitute a liberal turn, or rather a reverse immigration policy paradox of officially welcoming but covertly rejecting irregular migrants. Based on the comparative analysis of Argentina, Brazil and Ecuador, the study identifies and explains South American “populist liberalism” in the sphere of migration. We highlight important implications for migration theory, thereby opening up new avenues of research on immigration policy making outside Western liberal democracies, and particularly in predominantly migrant sending countries.     

Admissibility intervals for linear correlation coefficients

The correlation coefficient is widely used to quantify the degree of association between two quantitative variables. By resorting to the geometric representation of the linear correlation coefficient, it is possible to calculate the upper and lower bounds of the correlation coefficient between two variables x ₁,x ₂ when the correlation coefficients with a third variable x ₃ are available. Implications in observational studies, where x ₃ could be a proxy of a target variable x ₂, whose direct measurement is too expensive or impractical, are discussed.
