Slashed generalized Rayleigh distribution

We introduce a new family of distributions suitable for fitting positive data sets with high kurtosis which is called the Slashed Generalized Rayleigh Distribution. This distribution arises as the quotient of two independent random variables, one being a generalized Rayleigh distribution in the numerator and the other a power of the uniform distribution in the denominator. We present properties and carry out estimation of the model parameters by moment and maximum likelihood (ML) methods. Finally, we conduct a small simulation study to evaluate the performance of ML estimators and analyze real data sets to illustrate the usefulness of the new model.     

Adaptation of the short version of the Psychological Capital Questionnaire (PCQ-12) into Spanish / Adaptación al español de la versión reducida del Cuestionario de Capital Psicológico (PCQ-12)

Psychological capital (PsyCap) has been a topic of increasing interest in the last decade. However, there is a lack of validated instruments in Spanish to map PsyCap and its consequences for individuals’ well-being. Consequently, the goal of this study is to adapt the 12-item short version of the Psychological Capital Questionnaire (PCQ-12) to the Spanish context by analysing its internal consistency and reliability, factor solution and external validity. Results indicated that the PCQ-12 exhibited good Cronbach’s alpha (.87) and omega coefficient (.93) values in a sample from a vehicle inspection company (n = 798). As expected, results also revealed that a second-order factor structure provided the best fit. Moreover, PsyCap is associated with increased job engagement (β = .579; R²_adjusted = .333), decreased job burnout (β = ?.409; R²_adjusted = .166), and lower psychological distress (β = ?.349; R²_adjusted = .121) (all p < .01), which provided additional support for using the PCQ-12 in the Spanish context. Implications for theory and practice are discussed.

Use of Poset Theory with Big Datasets: A New Proposal Applied to the Analysis of Life Satisfaction in Italy

The aim of this work is to propose a tool for measuring a complex concept, and to apply it to big sets of data measured on ordinal and/or dichotomous scales. An important field of application are subjective data, that are often based on opinions or personal evaluations. Many national and international surveys employ this kind of data, measured among thousand of individuals. Thanks to the use of the “average rank” as a synthetic measure of a complex concept, we believe that poset theory could be a very useful approach for dealing with ordinal data avoiding the use of scaling procedures. Because classic poset approaches are at their best when applied to few data at a time, our idea is based on a procedure for sampling units from a big population using a simple criterion to summarize the resulting values appropriately. Applying the central limit theorem enables a comparison of the results obtained from different groups using statistical tests on the means. We used our Height of Groups by Sampling (HOGS) method to compare the average rank among groups that are defined by one or more socio-demographic variables influencing the level of the complex concept we wish to measure. The application of the HOGS procedure to life satisfaction in Italy generated convincing results, revealing significant differences between regions, genders and levels of formal education. We compared the results given by HOGS with the non linear principal component analysis and obtain an easy readable output with convincing precision and accuracy; we are confident that the HOGS procedure can be applied to many other concepts investigated in the social sciences.

On Old-Fashioned Versus Modern Homonegativity Distinction: Evidence From Poland

Psychological research on prejudice against homosexuals distinguishes between old-fashioned (traditional) and modern (contemporary) homonegativity, which differ with regard to their content, correlates, and consequences. The current research offers evidence for the validity of old-fashioned versus modern homonegativity distinction in the post-communist, East European context. In Studies 1 and 2 (Ns = 295 and 327, respectively) the Polish adaptations of the non-gendered and gendered Homonegativity Scale (Morrison, Parriag, & Morrison, 1999) and the Modern Homonegativity Scale (Morrison & Morrison, 2003) were developed. Furthermore, divergent (discriminant) validity of traditional and contemporary anti-homosexual prejudice was demonstrated. Old-fashioned and modern homonegativity exhibited differential relationships with social distance and support for same-sex couples’ relational rights.     

“Unnatural Fornication” Cases Under State-Socialism: A Hungarian–Slovenian Comparative Social-Historical Approach

This comparative social-historical study examines different versions of state-socialist body politics manifested in Hungary and Slovenia mainly during the 1950s by using archive material of “unnatural fornication” court cases. By analyzing the available Hungarian “természet elleni fajtalanság” and Slovenian “nenaravno ob?evanje” court cases, we can shed light on how the defendants were treated by the police and the judiciary. On the basis of these archive data that have never been examined before from these angles, we can construct an at least partial picture of the practices and consequences of state surveillance of same-sex-attracted men during state-socialism. The article explores the functioning of state-socialist social control mechanisms directed at nonnormative sexualities that had long-lasting consequences on the social representation of homosexuality in both countries.     

Patterns of im/mobility,conflict and the re/making of identity narratives*

ABSTRACT

This paper analyses the interrelationship between patterns of im/mobility on the one hand and the reconstitution of social collective identities and the related emergence or settlement of conflicts on the other. The main arguments are (1) that the im/mobility of a social or cultural group has major impact on how identity narratives, a sense of belonging and relationships to ‘others’ are shaped, and vice versa, and (2) that these dynamics are closely interlinked with mechanisms of inclusion and exclusion between groups and power structures that involve a broad variety of actors. Mainly looking at patterns of internal mobility such as ‘traditional’ or strategic mobilities and mobilities enforced by crisis, conflict or governmental programmes and regimes, the contribution provides the conceptual background for a special issue that aims to go beyond currently predominant issues of transnational migration. Established or emerging dynamics of (non-)integration and belonging, caused by im/mobility, are analysed on a cultural and political level, which involves questions of representation, indigeneity/autochthony, political rights and access to land and other resources. Conflict situations in contexts of mobility involve changes in the social understanding and renegotiation, reconstruction or reproduction of group identities and narratives with reference to certain socio-political and historical patterns. The legitimation of rights and access to various forms of citizenship and mobility need to be understood against the backdrop of emerging or established mechanisms of inclusion and exclusion between groups, which trigger or settle conflicts and make social identities to be constantly renegotiated.     

Interpreting conflict and integration through the reciprocity lens: mobility and settlement in a historical perspective on the Sierra Leonean coast

ABSTRACT

In recent years, Sierra Leone has witnessed intense population movements. During the civil war (1991–2002), many populations fled the fighting zones of the interior to take refuge on the coast. Since the conflict ended, new populations have reached the coastal area with the hope of accessing economic opportunities in the fishing business. Mobility, along with changing sociopolitical and economic conditions, has generated conflict between immigrants and Sherbro populations, who consider themselves autochthonous and deny migrants the freedom to access political and land rights. The paper argues that present dynamics of conflicts are rooted in long-term patterns of settlement and relationships of reciprocity between groups. Relations between migrants and local populations are grounded in a sociocultural idiom that implies the institutionalization of practices of reciprocity between local inhabitants (hosts) and later settlers (strangers). The host/stranger reciprocity system is an emic model of cultural action embedded in historical and power relations between groups. It implies the progressive integration of strangers into the host society. This paper highlights how, in a situation of conflict, long-established social relationships between groups are reevaluated with reference to norms of integration and reciprocity. The paper draws on Sherbro oral traditions to show how social memories about interethnic relations are reframed with reference to values and expectations of reciprocity, in order to explain the recent conflict that opposes Sherbros to immigrants. Sherbros use oral traditions to interpret these tensions in a long-term perspective, thereby expressing their own view on settlement, conflict and integration.
