Paying for permanence: Public preferences for contaminated site cleanup

We use conjoint choice questions to investigate the preferences of people in four cities in Italy for income and future/permanent mortality risk reductions delivered by contaminated site remediation policies. The VSL is €5.6 million for an immediate risk reduction. If the risk reduction takes place 20 years from now, the implied VSL is €1.26 million. Respondents’ implicit discount rate is 7%. The VSL depends on respondent characteristics, familiarity with contaminated sites, concern about the health effects of exposure to toxicants, having a family member with cancer, perceived usefulness of public programs and beliefs about the goals of government remediation programs.

The Interpretative Dimension of Transformative Events: Outrage Management and Collective Action Framing After the 2001 Anti-G8 Summit in Genoa

By focusing on the aftermath of the 2001 G8 counter-summit in Genoa, this paper aims to provide a comprehensive insight into the interpretative dimension of transformative events leading to backfire. First, in line with the existing literature on transformative events, the study shows that after the violent events, Italian authorities employed all possible strategies to inhibit public outrage (i.e., cover-ups of the situation, stigmatizations of targets to legitimate repressive action, reinterpretations of police violence as different from direct attacks, presence of authoritative assessments and intimidation of participants and witnesses). Second, a multidimensional scaling of symbolic devices from 70 social forum websites shows that after 2001, Italian social movement actors used the narrative of the Genoa events in deliberative (i.e., bridging, extension) or negotiating (i.e., punctuation, articulation) framing processes to build new collective action frames.     

Expert and Public Perception of Risk from Biotechnology

Risk perceptions of a series of biotechnology applications were examined in a public (nonexpert) sample and an expert sample. Compared with the experts, the public perceived all biotechnology applications as more risky. Both groups perceived food-related applications to be riskier than medical applications. Compared with the public, experts perceived both food and medical applications as less harmful and more useful. Experts also judged the risks posed from medical biotechnology applications as more familiar and acknowledged by people and science. Lay estimates of the risk of food applications were predicted by potential harm, potential benefits, science knowledge, and familiarity; experts' estimates were predicted only by harm and benefits. Lay estimates of the risk of medical applications were predicted by potential harm; experts' estimates were predicted by potential benefits, number and type of people exposed, and science knowledge. We discuss the implications of the results for risk communication about and management of different types of biotechnologies.     

Human Capital,Wages and Family Interactions

The majority of studies of the returns to human capital investment have generally considered the relationship among wages and individuals’ investment in education. However, among factors which increase individuals’ stocks of human capital and affect their labour market performances there are variables linked to the relevant social environment, such as the family. This paper takes into consideration intra‐generational relations which form between spouses through marriage, as well as inter‐generational relationships between parents and their sons/daughters. The empirical work investigates the effects of some family background variables on individuals’ economic performances, using data drawn from the 1995 survey of household income and wealth conducted by the Bank of Italy. The results of the analysis show that individuals’ wages do not depend only on their own human capital endowment, but also on that of other family members (parents and partners).     

Explaining subnational variations in early childhood education and care. A fuzzy‐set analysis of the Italian case

Although cross‐country differences in the development of early childhood education and care (ECEC) services have been widely researched, the pronounced subnational variation that characterizes many countries is little researched. This article aims to contribute filling this gap by investigating the factors underlying ECEC development in Italian regions, where take‐up rates of public and subsidized daycare centers, behind a national average of 12%, range from 2% in some Southern regions to 25% in Emilia Romagna (North‐East). The article explores the configurations of economic, socio‐demographic, political, institutional, and cultural factors possibly responsible for high and low ECEC development through Fuzzy‐set/Qualitative Comparative Analysis. Results show that economic development and female employment are necessary but not sufficient conditions for ECEC development; similarly, familistic values, the lack of early ECEC development and of social capital are necessary but not sufficient conditions for limited expansion. The analysis identifies multifaceted patterns of (non)expansion, thus demonstrating the complexity of social policy development processes and preventing determinism based on need, cultural, or economic factors.     

A BAYESIAN METHOD FOR THE CHOICE OF THE SAMPLE SIZE IN EQUIVALENCE TRIALS

In this paper we consider a Bayesian predictive approach to sample size determination in equivalence trials. Equivalence experiments are conducted to show that the unknown difference between two parameters is small. For instance, in clinical practice this kind of experiment aims to determine whether the effects of two medical interventions are therapeutically similar. We declare an experiment successful if an interval estimate of the effects‐difference is included in a set of values of the parameter of interest indicating a negligible difference between treatment effects (equivalence interval). We derive two alternative criteria for the selection of the optimal sample size, one based on the predictive expectation of the interval limits and the other based on the predictive probability that these limits fall in the equivalence interval. Moreover, for both criteria we derive a robust version with respect to the choice of the prior distribution. Numerical results are provided and an application is illustrated when the normal model with conjugate prior distributions is assumed.

Networks of Contention: The Shape of Online Transnationalism in Early Twenty-First Century Social Movement Coalitions

The study of new media use by transnational social movements is central to contemporary investigations of social contention. In order to shed light on the terrain in which the most recent examples of online mobilization have grown and developed, this paper combines the interest in the transnational dynamics of social contention and the exploration of the use of new information and communication technologies (ICTs) for protest action. In specific terms, the study investigates how early twenty-first century social movement coalitions used Internet tools to build symbolically transnational collective identities. By applying a hyperlink network analysis approach, the study focuses on a website network generated by local chapters of the World Social Forum (WSF), one of the earliest social movement coalitions for global justice. The sample network, selected through snowball sampling, is composed of 222 social forum websites from around the world. The study specifically looks at hyperlinks among social forum websites as signs of belonging and potential means of alliance. The analysis uses network measures, namely of cohesion, centrality, structural equivalence and homophily, to test dynamics of symbolic collective identification underlying the WSF coalition. The findings show that in early twenty-first century transnational contention, culture and place still played a central role in the emergence of transnational movement networks.
