Beliefs about the etiology of homosexuality and about the ramifications of discovering its possible genetic origin

Homosexuality is viewed by many as a social problem. As such, there is a keen interest in elucidating the origins of homosexuality among many scholars, from anthropologists to zoologists, from psychologists to theologians. Research has shown that those who believe sexual orientation is inborn are more likely to have tolerant attitudes toward gay men and lesbians, whereas those who believe it is a choice have less tolerant attitudes. The current qualitative study used in-depth, open-ended telephone interviews with 42 White and 44 Black Americans to gain insight into the public's beliefs about the possible genetic origins of homosexuality. Along with etiological beliefs (and the sources of information used to develop these beliefs), we asked respondents to describe the benefits and dangers of scientists discovering the possible genetic basis for homosexuality. We found that although limited understanding and biased perspectives likely led to simplistic reasoning concerning the origins and genetic basis of homosexuality, many individuals appreciated the complex and interactive etiological perspectives. These interactive perspectives often included recognition of some type of inherent aspect, such as a genetic factor(s), that served as an underlying predisposition that would be manifested after being influenced by other factors such as choice or environmental exposures. We also found that beliefs in a genetic basis for homosexuality could be used to support very diverse opinions including those in accordance with negative eugenic agendas.     

Applying classification algorithms in practice

In this paper we present a perspective on the overall process of developing classifiers for real-world classification problems. Specifically, we identify, categorize and discuss the various problem-specific factors that influence the development process. Illustrative examples are provided to demonstrate the iterative nature of the process of applying classification algorithms in practice. In addition, we present a case study of a large scale classification application using the process framework described, providing an end-to-end example of the iterative nature of the application process. The paper concludes that the process of developing classification applications for operational use involves many factors not normally considered in the typical discussion of classification models and algorithms.     

Adolescent and parent alliances with therapists in Brief Strategic Family Therapy with drug-using Hispanic adolescents

This study examined the relationship between alliance and retention in family therapy. Alliance was examined at the individual (parent, adolescent) and family level (within-family differences) for families that either dropped out or completed family therapy. Participants were 31 Hispanic adolescents and their family members who received brief strategic family therapy for the treatment of adolescent drug use. Videotapes of first sessions were rated to identify parent and adolescent alliances with the therapist. Results demonstrated that Completer cases had significantly higher levels of alliance across all family members than Dropout cases, and Dropout cases had significantly higher unbalanced alliances than Completer cases. Clinical implications are discussed.     

How do sustainability reports from the Nordic and the Mediterranean European countries compare

This study investigates the sustainability reporting practices of companies based in the Nordic and the Mediterranean European countries for the period 2013–2015. Its purpose is to analyse to what extent, if any, are there differences in these practices. It seeks to capture the influence of national institutions and firm specific characteristics in sustainability reporting. Non-parametric statistics are used to analyse some factors which influence disclosure, namely country, industry affiliation, type of property, listing status and size. In accordance with the theoretical frame used, that of the varieties of capitalism approach, findings suggest that in general companies from Mediterranean European countries present higher levels of engagement with the Global Reporting Initiative.

Effects of Track and Threat Information on Judgments of Hurricane Strike Probability

Although evacuation is one of the best strategies for protecting citizens from hurricane threat, the ways that local elected officials use hurricane data in deciding whether to issue hurricane evacuation orders is not well understood. To begin to address this problem, we examined the effects of hurricane track and intensity information in a laboratory setting where participants judged the probability that hypothetical hurricanes with a constant bearing (i.e., straight line forecast track) would make landfall in each of eight 45 degree sectors around the Gulf of Mexico. The results from 162 participants in a student sample showed that the judged strike probability distributions over the eight sectors within each scenario were, unsurprisingly, unimodal and centered on the sector toward which the forecast track pointed. More significantly, although strike probability judgments for the sector in the direction of the forecast track were generally higher than the corresponding judgments for the other sectors, the latter were not zero. Most significantly, there were no appreciable differences in the patterns of strike probability judgments for hurricane tracks represented by a forecast track only, an uncertainty cone only, or forecast track with an uncertainty cone—a result consistent with a recent survey of coastal residents threatened by Hurricane Charley. The study results suggest that people are able to correctly process basic information about hurricane tracks but they do make some errors. More research is needed to understand the sources of these errors and to identify better methods of displaying uncertainty about hurricane parameters.     

A Hierarchical Ordinal Probit Model for the Analysis of Life Satisfaction in Italy

The aim of this paper is to study the individual and contextual determinants of life satisfaction in Italy. A hierarchical probit model is proposed for studying data with group structure and an ordinal response variable. The group structure is defined by the presence of micro observations embedded with regional contexts (macro observations), and the specification is at both of these levels. The methodology is applied to Eurobarometer survey data, with individuals viewed as micro observations and regions as macro observations. We find that Italy is not an homogeneous country with respect to life satisfaction, and that the regional environment contributes with the observed and unobserved characteristics of the individuals to life satisfaction level.     

Who Enjoys the Fruits of Growth? Impact of Governments and Markets on Living Standards in Germany,The Netherlands and the U.S.A., 1987–1996

The 1980s and 1990s have been decades of quitegood economic growth in North America and muchof Western Europe. But how have the fruits ofgrowth been shared? This paper reviews changingincome distributions in the U.S., Germany and theNetherlands. These three countries may be takenas exemplars and leading economic performers in``the three worlds of welfare capitalism''(Esping-Andersen, 1990). The U.S. is a liberalwelfare-capitalist state, Germany a corporatiststate, and the Netherlands (less clearly) asocial democratic welfare-capitalist state. Thepaper focuses particularly on income changes inthe bottom, middle and top quintiles and takesa ten year period into account.Previous analyses have shown that labor andmarket income dispersion are increasing, withincreased returns to human capital. Thepotential impact of government through thetax-transfer system has been largely ignored.All three governments redistribute income fromthe rich to the poor. However, the paper showsthat only the Dutch government hasredistributed sufficiently to ensure that thebottom quintile has gained along with others.In Germany and the U.S. the poorest quintile wasconsiderably worse off in absolute terms at theend of the decade.than the beginning. TheGerman government somewhat counteracted thetrend towards greater income dispersion byredistributing to the poorest quintile, so theloss of market income was partly compensated. In the U.S. the impact of government on thepoorest quintile stayed about the same, so thisgroup ended up with about the same decrease indisposable income as market income.The U.S., Germany and the Netherlands are theonly three countries for which ten or moreconsecutive years of panel data are available.The data come from the PSID-GSOEP EquivalentFile 1980-97 and from a comparable fileconstructed from the Dutch SEP data.

     

Strategy versus sincerity in mean voting

This paper focuses on the mean vote procedure for choosing the quantity of a public good, a social choice rule that selects the mean of the quantities voted for. The available theoretical models of mean voting give rise to conflicting predictions about the extent of the strategic bias that might arise in the individual vote. An experiment has been run in order to assess whether the participants disclose their (induced) preferences in voting or whether they strategically manipulate their vote, and in the latter case, which variables impact upon the likelihood of strategic bias and to what extent.
