The Status Attainment Process: a Test of a Model in Two Stratification Systems1

This paper examines how variations in status crystallization influence the status attainment process in two stratification systems: the kibbutz and the urban population in Israel. The first is an example of a weakly crystallized system; the second of a moderately crystallized one. The findings provide support for the proposition that in weakly crystallized systems status dimensions tend to affect only variables which measure equivalent dimensions, that is, corresponding variables, with minimal radiation of effects to non-corresponding ones. This pattern has been observed in the application of the status attainment model to the kibbutz. In the urban sample the pattern of effects is uneven. While there is a partial tendency of status dimensions to have a stronger effect on non-corresponding variables, the discrepancy between corresponding and noncorresponding effects is small.     

Causal dynamics of poverty reproduction in EU countries

This study investigated causal mechanisms of poverty reproduction in EU countries by placing emphasis on the parental background effect on sons’ poverty risk after having controlled for endogeneity among observable and non‐observable effects of the involved mechanisms. The countries under investigation were old EU member states representing the four welfare regimes in the EU. Having employed path models and utilised EU‐SILC 2005 data, the analysis yielded no statistically significant direct effect of parental background on sons’ poverty risk in Denmark. Greece, however, exhibited a statistically significant and quite strong direct effect. Germany and the United Kingdom stood in‐between. Moreover, the analysis found indirect channels through which the parental background affects sons’ poverty risk. These findings are expected to enrich the academic discourse and inform the policy‐making process on poverty reproduction and social protection in the EU.     

Dimensions of Identity Development Scale: Confirmatory factor analysis,gender invariance,and external validity of the Persian version

The present study was conducted to examine the psychometric properties and gender invariance of the Iranian version of the Dimensions of Identity Development Scale (DIDS). A total of 1453 adolescents (50.8% female; 14–18 years old, mean = 15.48) participated in a cross-sectional study and completed the DIDS and the Youth Self-Report of behavior problems. The Confirmatory Factor Analysis supported the six-factor model of the DIDS, echoing past studies showing the original 5th factor (Exploration in Depth) being divided into Exploration in Depth and Reconsidering the Commitment. The invariance testing showed comparable measurement properties of the DIDS across males and females (strict measurement invariance). Further, behavior problems were associated positively with Ruminative Exploration and negatively with Commitment Making, Identification with Commitments, Exploration in Depth, and Reconsideration of Commitments, whereas the opposite was true for academic performance. A six-factor DIDS was shown to be a valid and reliable measure for the assessment of identity development dimensions among Iranian adolescents. Future studies in the Iranian context evaluating the identity clusters derived from identity dimensions and their gender differences are warranted.     

Who cares about the environment?

ABSTRACT

Environmental behavior substantially differs among individuals depending on their environmental attitudes, connectivity to nature beliefs, and socioeconomic profile. People who adopt an eco-friendly lifestyle and those who are unconcerned about environmental protection represent population segments with diverse characteristics. Consequently, this study aims to identify homogeneous groups based on individuals’ environmental behavior. A total of 400 Greek citizens completed a self-report questionnaire. We used behavioral items adopted from previous studies to measure environmental behavior and background variables to assess the socio-demographic profile of the respondents. Additionally, we used the well-established measures of Connectedness to Nature Scale (CNS) and New Ecological Paradigm Scale (NEP) to measure people's relatedness with nature and their ecological beliefs separately. Multivariate Cluster Analysis results indicated that participants can be grouped into two broad segments, named moderate eco-friends and non-environmentalists. Individual differences between the clusters were detected with respect to gender, education, connectedness to nature and ecological worldview.     

Social work education in Cyprus: prospects and challenges in developing an indigenous character

The evolution of the social work education and welfare system in Cyprus is inextricably linked to the country’s recent turbulent history. Social Work in the Republic of Cyprus, although shaped by the country’s turbulent political past and present, is also influenced by Western theory as in many other countries in the Asian and African continent [Gray, M., & Fook, J. (2004). The quest for a universal social work: Some issues and implications, Social Work Education, 23(5), 625–644; Rankopo, M. J., & Hwedie, K. O. (2011). Globalization and culturally relevant social work: African perspectives on indigenization. International Social Work, 54(1), 137–147; Yip, K. S. (2007). Tensions and dilemmas of social work education in China. International Social Work, 50(1), 93–105]. In contrast with social welfare which has a long history (since late nineteenth century), social work education is still at an early stage of development in Cyprus. A non-surprising situation given that social work practice and education, in its early stages, is essentially a modernist Western invention which has a history of silencing marginal voices and importing, into diverse cultural contexts across the world, Western thinking primarily from the UK and the USA (Gray & Fook, 2004). However, if an indigenous social work character is to be developed in Cyprus, and a more distinctive identity with regard to the social work academic curricula is to be demonstrated, then Payne’s [(2001). Knowledge bases and knowledge biases in social work. Journal of Social Work, 1(2), 133–136] views on social work knowledge need further exploration.     

Real-time threat assessment based on hidden Markov models

An essential factor toward ensuring the security of individuals and critical infrastructures is the timely detection of potentially threatening situations. To this end, especially in the law enforcement context, the availability of effective and efficient threat assessment mechanisms for identifying and eventually preventing crime- and terrorism-related threatening situations is of utmost importance. Toward this direction, this work proposes a hidden Markov model-based threat assessment framework for effectively and efficiently assessing threats in specific situations, such as public events. Specifically, a probabilistic approach is adopted to estimate the threat level of a situation at each point in time. The proposed approach also permits the reflection of the dynamic evolution of a threat over time by considering that the estimation of the threat level at a given time is affected by past observations. This estimation of the dynamic evolution of the threat is very useful, since it can support the decisions by security personnel regarding the taking of precautionary measures in case the threat level seems to adopt an upward trajectory, even before it reaches the highest level. In addition, its probabilistic basis allows for taking into account noisy data. The applicability of the proposed framework is showcased in a use case that focuses on the identification of potential threats in public events on the basis of evidence obtained from the automatic visual analysis of the footage of surveillance cameras.
