Problem gambling and family violence : family member reports of prevalence, family impacts and family coping

There exists only a small number of empirical studies investigating the patterns of family violence in problem gambling populations, although some evidence exists that intimate partner violence and child abuse are among the most severe interpersonal correlates of problem gambling. The current article reports on the Australian arm of a large-scale study of the patterns and prevalence of co-occurrence of family violence and problem gambling in Australia, New Zealand and Hong Kong. The current study screened 120 help-seeking family members of problem gamblers in a range of clinical services for both family violence and problem gambling. The main results showed that 52.5% reported some form of family violence in the past 12 months: 20.0% reported only victimisation, 10.8% reported only perpetration and 21.6% reported both victimisation and perpetration of family violence. Parents, current and ex-partners were most likely to be both perpetrators and victims of family violence. There were no gender differences in reciprocal violence but females were more likely to be only victims and less likely to report no violence in comparison to males. Most of the 32 participants interviewed in depth, reported that gambling generally preceded family violence. The findings suggest that perpetration of family violence was more likely to occur as a reaction to deeply-rooted and accumulated anger and mistrust whereas victimisation was an outcome of gambler’s anger brought on by immediate gambling losses and frustration. While multiple and intertwined negative family impacts were likely to occur in the presence of family violence, gambling-related coping strategies were not associated with the presence or absence of family violence. The implications of the findings for service providers are discussed.

Adolescent depressive disorders and family based interventions in the family options multicenter evaluation: study protocol for a randomized controlled trial

Background
There is increasing community and government recognition of the magnitude and impact of adolescent depression. Family based interventions have significant potential to address known risk factors for adolescent depression and could be an effective way of engaging adolescents in treatment. The evidence for family based treatments of adolescent depression is not well developed. The objective of this clinical trial is to determine whether a family based intervention can reduce rates of unipolar depressive disorders in adolescents, improve family functioning and engage adolescents who are reluctant to access mental health services.

Methods/Design
The Family Options study will determine whether a manualized family based intervention designed to target both individual and family based factors in adolescent depression (BEST MOOD) will be more effective in reducing unipolar depressive disorders than an active (standard practice) control condition consisting of a parenting group using supportive techniques (PAST). The study is a multicenter effectiveness randomized controlled trial. Both interventions are delivered in group format over eight weekly sessions, of two hours per session. We will recruit 160 adolescents (12 to 18 years old) and their families, randomized equally to each treatment condition. Participants will be assessed at baseline, eight weeks and 20 weeks. Assessment of eligibility and primary outcome will be conducted using the KID-SCID structured clinical interview via adolescent and parent self-report. Assessments of family mental health, functioning and therapeutic processes will also be conducted. Data will be analyzed using Multilevel Mixed Modeling accounting for time x treatment effects and random effects for group and family characteristics. This trial is currently recruiting. Challenges in design and implementation to-date are discussed. These include diagnosis and differential diagnosis of mental disorders in the context of adolescent development, non-compliance of adolescents with requirements of assessment, questionnaire completion and treatment attendance, breaking randomization, and measuring the complexity of change in the context of a family-based intervention.

Mediators of the relationship between sedentary behavior and depressive symptoms amongst disadvantaged women

Statement of problem
Associations between sedentary behavior (e.g. time spent sitting watching TV/using the computer) and physical health have been well documented, however, studies are increasingly reporting a positive relationship between certain sedentary behaviors and poor mental health (e.g. depression). Little is known about the underlying factors that may explain the link between sedentary behavior and likelihood of depression. The purpose of this study was to investigate the contribution of selected intra-personal and social factors as potential mediators of the relationship between sedentary behavior and depressive symptoms among women from disadvantaged neighborhoods.
Method
Cross-sectional survey data were provided by 4065 women (aged 18–45) living in disadvantaged neighborhoods. Women self-reported their sedentary behavior (total sitting time and screen time), depressive symptoms (CES-D 10), as well as a number of intra-personal (leisure-time physical activity, diet quality, weight status) and social (social cohesion, interpersonal trust, club membership) factors.
Results
Mediating analyses, controlling for confounders, showed that women's leisure-time physical activity partly mediated the relationship between total sitting time and increased likelihood of depressive symptoms. Women's diet quality, and social cohesion partly mediated the relationship between screen time and increased likelihood of depressive symptoms.
Conclusions
Acknowledging the cross-sectional study design, findings suggest that there may be several factors that explain the increased likelihood of depressive symptoms associated with greater sedentary time. Although future studies should test the mediating relationships longitudinally, these findings may help inform interventions aimed at reducing the likelihood of depression in disadvantaged women with high sitting time.

Essays in political and development economics

 This research analyses the role of terrain ruggedness and elite domination as obstacles undermining the cooperation and cohesiveness of groups in societies. Specifically, terrain ruggedness hinders state capacity development and fiscal decentralisation could mitigate this negative effect. Additionally, it proves the role of elites in the selection of economic policies.

The effect of simulated thermomechanical processing on the transformation behavior and microstructure of a low-carbon Mo-Nb linepipe steel

The present work investigates the transformation behavior of a low-carbon Mo-Nb linepipe steel and the corresponding transformation product microstructures using deformation dilatometry. The continuous cooling transformation (CCT) diagrams have been constructed for both the fully recrystallized austenite and that deformed in uniaxial compression at 1148 K (875 °C) to a strain of 0.5 for cooling rates ranging from 0.1 to about 100 K/s. The obtained microstructures have been studied in detail using electron backscattered diffraction complemented by transmission electron microscopy. Heavy deformation of the parent austenite has caused a significant expansion of the polygonal ferrite transformation field in the CCT diagram, as well as a shift in the non-equilibrium ferrite transformation fields toward higher cooling rates. Furthermore, the austenite deformation has resulted in a pronounced refinement in both the effective grain (sheaf/packet) size and substructure unit size of the non-equilibrium ferrite microstructures. The optimum microstructure expected to display an excellent balance between strength and toughness is a mix of quasi-polygonal ferrite and granular bainite (often termed “acicular ferrite”) produced from the heavily deformed austenite within a processing window covering the cooling rates from about 10 to about 100 K/s.

Effects of alloying elements on the corrosion behavior and biocompatibility of biodegradable magnesium alloys: a review

Magnesium (Mg) based alloys have been extensively considered for their use as biodegradable implant materials. However, controlling their corrosion rate in the physiological environment of the human body is still a significant challenge. One of the most effective approaches to address this challenge is to carefully select alloying compositions with enhanced corrosion resistance and mechanical properties when designing the Mg alloys. This paper comprehensively reviews research progress on the development of Mg alloys as biodegradable implant materials, highlighting the effects of alloying elements including aluminum (Al), calcium (Ca), lithium (Li), manganese (Mn), zinc (Zn), zirconium (Zr), strontium (Sr) and rare earth elements (REEs) on the corrosion resistance and biocompatibility of Mg alloys, from the viewpoint of the design and utilization of Mg biomaterials. The REEs covered in this review include cerium (Ce), erbium (Er), lanthanum (La), gadolinium (Gd), neodymium (Nd) and yttrium (Y). The effects of alloying elements on the microstructure, corrosion behavior and biocompatibility of Mg alloys have been critically summarized based on specific aspects of the physiological environment, namely the electrochemical effect and the biological behavior.

Social competence following pediatric stroke: contributions of brain insult and family environment

Limited information is available regarding predictors of psychosocial difficulties in children following stroke. This study aimed to (i) compare social competence of children with arterial ischemic stroke (AIS) to those with chronic illness and healthy controls and (ii) investigate the contribution of stroke pathology, neurological outcome and environment. Thirty-six children with AIS > 12 months prior to recruitment were compared with children with chronic illness (asthma) (n = 15) and healthy controls (n = 43). Children underwent intellectual assessment, and children and parents completed questionnaires to assess social competence. Children with AIS underwent MRI scan and neurological evaluation. Child AIS was associated with poorer social adjustment and participation, and children with AIS were rated as having more social problems than controls. Lesion volume was not associated with social outcome, but subcortical stroke was linked to reduced social participation and younger stroke onset predicted better social interaction and higher self-esteem. Family function was the sole predictor of social adjustment. Findings highlight the risk of social impairment following pediatric stroke, with both stroke and environmental factors influencing children's social competence in the chronic stages of recovery. They indicate the potential for intervention targeting support at the family level.

Understanding the experience of inpatient rehabilitation: insights into patient-centred care from patients and family members

The aim of the study was describe the experiences, needs and preferences of recent inpatients of a rehabilitation centre, and the needs of their families. Data were collected in four focus groups, two with patients (n = 13) who had recently completed inpatient rehabilitation following an illness, injury or elective surgery, and two with family members (n = 11). During the focus groups, two researchers facilitated discussion on any topic that participants considered important to the experience of inpatient rehabilitation; participants were encouraged to describe their care, needs and preferences. The focus group discussions were audio-taped and transcribed verbatim. Field notes were hand recorded. Data were analysed and collated into themes. Six key themes emerged. Participants wanted: interactions with friendly, empathetic staff; regular contact with senior staff and all staff to introduce themselves by name and profession; timely communication of accurate information; and rehabilitation services seven days a week. The physical environment had both positive and negative effects on patient well-being. Patients with complex or atypical circumstances required special attention to ensure their needs were met. In conclusion, patients and families identified six important issues that need to be considered during inpatient rehabilitation.
