A Cautionary Note on the Use of the Grønnesby and Borgan Goodness-of-Fit Test for the Cox Proportional Hazards Model

Grønnesby and Borgan (1996, Lifetime Data Analysis 2, 315–328) propose an omnibus goodness-of-fit test for the Cox proportional hazards model. The test is based on grouping the subjects by their estimated risk score and comparing the number of observed and a model based estimated number of expected events within each group. We show, using extensive simulations, that even for moderate sample sizes the choice of number of groups is critical for the test to attain the specified size. In light of these results we suggest a grouping strategy under which the test attains the correct size even for small samples. The power of the test statistic seems to be acceptable when compared to other goodness-of-fit tests.     

A randomized controlled trial of the effects of mindfulness practice on doctoral candidate psychological status

Objectives: To examine the impact of guided mindfulness practice on psychological distress and psychological capital (hope, optimism, resilience, and efficacy) in doctoral candidates. Participants: Recruitment of a convenience sample of doctoral candidates occurred in July 2015 and participants were randomly allocated to the control or intervention group (38 and 34 participants completed the trial, respectively). Methods: A single-blinded, randomized controlled trial with intention-to-treat analysis was conducted. The intervention consisted of a daily guided mindfulness practice, using an audio CD. Indicators of psychological distress and psychological capital were measured pre- and post-trial with validated questionnaires. Results: Compared to the control group, the intervention group reported a statistically significantly reduction in depression (p?=?.045) and increased self-efficacy (p?=?.004), hope (p?=?.000), and resilience (p?=?.011). Conclusions: These results highlight the effectiveness of self-administered mindfulness practice on the psychological health of doctoral candidates, and the positive effect on psychological capital is reported as a key finding.     

Effects of Exogenous and Endogenous Distracters on Immediate and Long‐Term Recall in Toddlers

We explored the role that exogenous and endogenous competitors for attention play in infants’ abilities to encode and retain information over a 6‐month period. Sixty‐six children visited the laboratory at 15 months, and 32 returned for a second visit at 21 months. Children observed models of conventional‐ relation and enabling‐relation action sequences. Half the children were distracted by a “Mister Monkey” mechanical toy during the conventional‐relation sequence, while the other half was distracted during the enabling‐relation sequence. The Early Childhood Behavior Questionnaire indexed endogenous factors at both ages. Immediate postmodel production of target actions indexed encoding efficiency, and 6‐month production of target actions indexed long‐term recall. The exogenous distracter impacted encoding efficiency (i.e., immediate recall), but not long‐term recall. Endogenous factors (i.e., temperament) were primarily associated with long‐term recall. Of special interest was our finding that endogenous factors, especially surgency, moderated the effect of the exogenous distracter. It appears that when learning conventional‐relation sequences in the presence of exogenous distracters, surgency mobilizes attentional resources toward the learning objective; however, when learning enabling‐relation sequences under the same conditions, surgency either boosts the saliency of the distracters or boosts children’s susceptibility to them.     

Religious Coping and Glycemic Control in Couples with Type 2 Diabetes

This study examines the role of religious coping in couples’ diabetes management processes. Eighty‐seven couples where one spouse had type 2 diabetes were surveyed. The relationships between religious coping (positive and negative), shared glycemic control activities (e.g., planning a healthy diet), and glycemic control were examined using repeated measures ANOVA and SEM. Findings show spousal engagement in shared activities is significantly associated with glycemic control. Furthermore, the use of negative religious coping by the diabetic spouse, and positive religious coping by the nondiabetic spouse, related to lower levels and higher levels of shared glycemic control activities, respectively. Religious coping and shared glycemic control activities appear integral to couples managing type 2 diabetes and, may serve as useful points of intervention.     

Social work with Bosnian Muslim refugee children and families: a review of the literature

More than two million Bosnian Muslims were ethnically cleansed in the Balkan region; of these, 200,000 were killed while the others were forced to flee their homes and become refugees. This article focuses on the influence of societal and cultural values coupled with wartime experiences on the transition of Bosnian refugee families to their new countries. Consideration is given to culturally competent theoretical frameworks and practice principles social workers can use to assist Bosnian Muslim children and families in their adaptation process within their resettlement communities.     

Organising Services for People with Mental Handicap: The Californian Experience

The organisation of services for California's mentally handicapped population is outlined and critically examined. Its distinctive features are noted: a concern for rights, rather than needs; an underlying free market philosophy; an explicit attempt to combine public and private enterprise; and an elaborate system of checks and balances designed to restrain the welfare bureaucracies and ensure that they remain responsive to the changing nature of individual need. It is argued that, despite certain limitations, the Californian system does seriously address three problems that bedevil all attempts to develop a satisfactory system of care for people with mental handicaps: the inherent powerlessness of the client group; the diversity and fragmentation of services; and bureaucratic inertia.     

THE INFORMATION SOCIETY AS MEGA-MACHINE

Too often the history of information and communication technologies (ICTs) is wrenched out of the history of technology and presented as something altogether separate and therefore different, rendering previous analyses irrelevant. However, there are sufficient analytical tools to hand without the continual invention of new paradigms to understand the current stage of technological advance. To support this contention, in this article, the continuing relevance of Lewis Mumford is explored. Mumford's discussion of the megalopolis and the emergence of the invisible city as its most developed state make a direct link with the networked information society, establishing a link between the information society and Mumford'sanalysis of the previous history of technology.At the centre of Mumford'sdiscussion of this history is the dialectic interaction of authoritarian and democratic technics. Mumford's notion of technics stresses that technologies can not be divided from the social relations in which they appear. In the information society,this dialectical pair map onto the twin dynamics of enclosure and disclosure. The former dynamic represents the control of information through commodification and marketization, the latter the recognition of the empowering and emancipatory qualities of ICTs. Up until now,discussions of the information society have regarded only one or other dynamic as normal, whereas utilizing Mumford'sinsight, the contradictory character of the information society can be theorized without rendering the second dynamic abnormal. Thus, the article concludes that recourse to Mumford's ideas, to re-embed ICTs in the history of technology, allows a more nuanced and fruitful treatment of current developments in information society.     

The effect of exposure to a professor with a visible disability on students' attitudes toward disabilities

An exploratory study was conducted on a small convenience sample of undergraduate social work students. The Modified Issues in Disability Scale was used to collect data on attitudes toward disability. There was no statistically significant difference in the attitudes scores among students who had different levels of contact with persons with disabilities. There was, however, a statistically significant difference between students who had a professor with a disability and those who did not. The former had more positive attitudes toward disability. These findings suggest that schools of social work should recruit more professors with disabilities.     

Pathways from Casual Employment to Economic Security: the Australian Experience

Casual employment is extensive and has been increasing for more than two decades in Australia. The concept of casual employment used in the Australian context is unusual, but it is directly linked to benefit and rights exclusion within the regulatory framework governing employment. The expansion in casual employment has spread across all sectors, industries and occupations. Casual employment is associated with various forms of insecurity including income and employment insecurity. There are a number of ways in which the insecurity associated with casual employment could be reduced.
