Estimation of the Renyi’s residual entropy of order \alpha with dependent data

In the present paper, we propose nonparametric estimators for the Renyi’s information measure for the residual lifetime distribution based on complete and censored data. This measure plays important roles in reliability and survival analysis in connection with modeling and analysis of life time data. Asymptotic properties of the estimators are established under suitable regularity conditions. Monte-Carlo simulation studies are carried out to compare the performance of the estimators using the mean-squared error. The methods are illustrated using real data sets.     

Psychosocial Correlates and Consequences of Adolescents’ Self‐Generated Academic Goals and Appraisals

The current study examined whether characteristics of adolescents (i.e., externalizing problems) and their environments (i.e., social support, adverse childhood experiences) relate to academic goal setting, appraisals, and outcomes. Adolescents (n = 99; 87% Black/African American) 13–16 years old completed baseline interviews, and 80% also completed follow‐up interviews. Adolescents with more externalizing problems set fewer academic goals, and youth with social networks characterized by greater support (and less strain) appraised their academic goals as more supported and achievable. Adolescents’ appraisals of their academic goals, but not how many academic goals they had, predicted grades at follow‐up. Increasing social support (and reducing social strain) may foster adolescents’ positive appraisals of their academic goals, which may promote academic achievement.     

Object-oriented design of a distributed agent-based framework for e-Procurement

Procurement is an important function in any manufacturing organization and it also has strategic business value attached to it. Hence, any improvements in the process would result in tremendous benefits. E-Procurement exploits the Internet and agent technologies to conduct procurement-related processes. In this paper, we design and develop a software agent-based framework for a typical e-Procurement process by decomposing it into three business processes: e-Negotiations, reverse auctions and e-Settlement. The artefacts of the system for each of the three business processes have been designed and developed using Unified Modeling Language (UML). A prototype of one of the processes, viz. reverse auction, has also been implemented.     

DIRECTIVE AND NONDIRECTIVE SPOUSAL SUPPORT: DIFFERENTIAL EFFECTS?

In this study we investigated whether the following factors influenced married partners' reactions to spousal support: type of support (directive vs. nondirective); individual differences (gender, depressive symptoms); and dimension along which support was evaluated (level of helpfulness vs. valence of emotional impact). Nondirective support was consistently rated more favorably on the dimension of partner's impact than on the dimension of partner's helpfulness, and this effect was exaggerated for those self-reporting a high level of depressive symptoms. Nonetheless, directive support was provided more frequently than was nondirective support in this sample. Gender differences and complications introduced by partner dysphoria suggest some situations in which directive support may be particularly difficult to provide effectively. Implications for couple therapy are discussed.     

Reflections on discrimination and oppression in contemporary social work practice in Bulgaria

This article draws on a study of awareness and sensitivity towards discrimination and oppression in contemporary practice in the Bulgarian social system through the perspectives of helping professionals and social clients. To that end, empirical data were gathered through a study of: the knowledge and awareness about anti-discrimination policy and legislation in the social sphere; awareness and perceptions of discrimination and oppression in society and the social work domain; and reflections on discrimination and oppression in the context of working relationships. Two questionnaires were designed and used to collect data in the period of April–May 2014 in the Southwestern region of Bulgaria. There were two groups consisting of 132 helping professionals (n?=?132) and 121 clients/service users (n?=?121). Both groups had low awareness of anti-discrimination legislation and regulations in the field of social policy and services. Discrimination and oppression were perceived as widespread phenomena that affected life of disadvantaged groups and also manifested in the social system. Ethnic minority service users needed information about their rights and community resources and claimed for larger involvement in the process of social work.     

Between the Social and the Personal: Israeli Male Gay Parents,Surrogacy and Socio-Political Concepts of Parenthood and Gender

This work focuses on the effects of dominant concepts of parenthood and gender on gay men who became parents through surrogacy. Based on the analysis of 39 in-depth, semistructured interviews with gay fathers, we show that gay fathers' parenting experiences are shaped by the heteronormative discourse on parenthood, yet they resist its gendered attributes. Gay parenthood is revealed as confronting the social concepts on parenthood, in particular on motherhood, and their socio-political meanings. The tension between the social concepts and the participants' perceptionsy leads them to confront their social environment and to construct alternative discourse to the social discourse of parenthood and gender, suggesting that gay parenthood subverts under existing concepts of parenthood, gender and their meanings within the state.
