Abuse of disabled children in Ghana

Even though disabled children are targets of various forms of abuse, such issues remain mostly undocumented open secrets in many countries including Ghana. The article is based on a qualitative data provided by three key informants. Six stories emerged from the data and are discussed in terms of four main forms of abuse. Labelling theories are employed to strengthen the discussions. The article is aimed at increasing awareness on the various forms of abuse experienced by disabled children in Ghana. The study is also meant to capture the attentions of stakeholders that have the responsibility to end abusive practices against disabled children in Ghana.     

Development and validation of the Protective Gambling Beliefs Scale (PGBS)

This article aimed to develop and validate a measure of protective beliefs – distinct from the absence of erroneous beliefs – that may be associated with resistance to gambling problems. Study 1 was designed to determine the reliability and content validity of a preliminary set of protective belief items. Participants (N = 1479, 813 males) also completed the Problem Gambling Severity Index (PGSI). Most items were associated with reduced risk of problems; however, items relating to an awareness of gambling harm, and preparedness to lose money were positively correlated with gambling problems and were therefore not demonstrably protective. Study 2 sought to reduce scale size and assess the scale’s ability to predict risk of gambling problems. Participants (N = 1168, 625 males) completed belief items, the PGSI, and measures of gambling consumption and cognitive distortions. Results showed that endorsement of protective beliefs was negatively correlated with PGSI, gambling consumption and cognitive distortions, and predicted PGSI above that of cognitive distortions. Findings suggest that the Protective Gambling Beliefs Scale (PGBS) offers a unique tool for understanding resistance to the development of gambling problems. Future research should focus on exploring whether protective beliefs can diminish the likelihood of the onset of problem gambling.     

The Cat and the Cloud: ACT for LGBT Locus of Control,Responsibility, and Acceptance

Advocating acceptance, committed action, and value-guided behavior over experiential avoidance, Acceptance and Commitment Therapy (ACT) may aid lesbian, gay, bisexual and transgender (LGBT) clients affected by hetero/homonormative social pressure. By conceptualizing LGBT paradigms of internal/external control/responsibility (IC-IR; EC-IR; IC-ER; EC-IR), ACT may be adapted to a myriad of multicultural worldviews. This article presents locus of acceptance as the attributed worth of internal/external cues perceived necessary by the client to achieve self-acceptance. Recognizing visibility and isolation as recurrent LGBT issues, locus of acceptances balances identity as individual (internal acceptance) with identity as community (external acceptance).     

Liberalisierungspolitik

Political-economic classics of different schools agreed that capitalism inherently and inevitably leads to a decline of market principles. We analyze indicators of liberalization policies for 21 OECD-countries in five economic and social policy fields and demonstrate that western industrialized countries are subject of a convergent trend towards market-creating policies??in stark contrast to the theoretical expectations of several political economy authors. At the latest during the first half of the eighties, the western democracies entered a new phase of economic liberalization, which continues up to the present. A methodological implication of our findings suggests that the methods of causal analysis of convergent liberalization policies may not be the same as those who have been applied for the analysis of development and consolidation of the varieties of capitalism in the postwar era.     

Immigration without adaptation: The psychological world of Russian immigrants in Israel

This study examines new immigrants from the former USSR, their attitudes, expectations and the awareness of change in themselves and in their fellow immigrants. Participants demonstrated attitudes toward the new society which differed dramatically depending on the sphere of life being examined: cultural, institutional, or quotidian. Participants displayed a tendency toward integration in the institutional and quotidian spheres, but not in the cultural. An attitude toward integration did not automatically lead to an awareness of change in the new immigrants themselves. Participants consistently reported higher degrees of change in fellow immigrants in comparison to themselves. The issue of preservation of self‐identity through socio‐cultural conservation is discussed, as well as the relevance of these findings for Vygotsky's cultural‐historical theory and Feuerstein's theory of mediated learning.     

A quasi-Newton acceleration for high-dimensional optimization algorithms

In many statistical problems, maximum likelihood estimation by an EM or MM algorithm suffers from excruciatingly slow convergence. This tendency limits the application of these algorithms to modern high-dimensional problems in data mining, genomics, and imaging. Unfortunately, most existing acceleration techniques are ill-suited to complicated models involving large numbers of parameters. The squared iterative methods (SQUAREM) recently proposed by Varadhan and Roland constitute one notable exception. This paper presents a new quasi-Newton acceleration scheme that requires only modest increments in computation per iteration and overall storage and rivals or surpasses the performance of SQUAREM on several representative test problems.     

Statistical analysis for Kumaraswamy’s distribution based on record data

In this paper we review some results that have been derived on record values for some well known probability density functions and based on m records from Kumaraswamy’s distribution we obtain estimators for the two parameters and the future sth record value. These estimates are derived using the maximum likelihood and Bayesian approaches. In the Bayesian approach, the two parameters are assumed to be random variables and estimators for the parameters and for the future sth record value are obtained, when we have observed m past record values, using the well known squared error loss (SEL) function and a linear exponential (LINEX) loss function. The findings are illustrated with actual and computer generated data.
