Illness cognitions and coping self-efficacy in depression among persons with low vision

PURPOSE: To investigate the mediating role of coping self-efficacy (CSE) between two types of illness cognitions (i.e., acceptance and helplessness) and depressive symptoms in persons with low vision.

METHODS: This was a single-group, cross-sectional study. Patients with visual acuity < 6/12 in the better eye and at least minimal depressive symptoms (≥5 on the Patient Health Questionnaire-9 [PHQ-9]) were recruited from vision rehabilitation services and participated in telephone-administered structured interviews at one time point. Measures were the PHQ-9, CSE Scale, and Illness Cognition Questionnaire. Structural equation modeling (SEM) devised the causal flow of illness cognitions and their observed indirect effects on depressive symptoms via the CSE mediators: problem focused, emotion focused, and social support.

RESULTS: The study comprised 163 patients (mean age 62 years; 61% female), most with age-related macular degeneration (26%) and moderate vision impairment (44%, <6/18-6/60). Structural equation modeling indices indicated a perfect fit (χ2 < 0.001, P = 1.00), accounting for 55% of the variance in depressive symptoms. Lower levels of acceptance and higher levels of helplessness illness cognitions were associated with lower self-efficacy in problem-focused coping (β = 0.38, P < 0.001, β = -0.28, P < 0.01, respectively), which in turn was associated with greater depressive symptom severity (β = -0.54, P < 0.001).

CONCLUSIONS: Lack of acceptance and greater helplessness relating to low vision led to a lack of perceived capability to engage in problem-focused coping, which in turn promoted depressive symptoms. Third-wave cognitive-behavioral treatments that focus on acceptance may be efficacious in this population.

A self-representation analysis of the effects of individualist-collectivist interactions within organizations in individualistic cultures

Purpose – Increasingly, organizations in the Asia-Pacific region are recognizing the importance of cross-cultural management to the sustainability of their competitive edge. Although the literature is replete with cross-cultural studies of individualism and collectivism, little information is available on the factors that foster effective individualist–collectivist interaction (ICI) within organizations. This paper attempts to provide a theoretical description of individualists and collectivists at the individual
level of analysis, which offers specific testable hypotheses about the effect of self-representation on prejudice between individualists and collectivists (ICs).

Design/methodology/approach – In this paper, a theoretical model is presented in which intergroup prejudices and interpersonal prejudices mediate the effects of ICI and bicultural orientation toward cross-cultural experiences and, in which, the dissimilarity openness of the climate
moderates the level and outcome of prejudices flowing from ICI.

Findings – The model depicts that the outcomes of ICI are mediated by the intergroup prejudices of collectivists and the interpersonal prejudices of individualists, which are moderated by the extent of diversity-oriented HRM policies and practices and individuals’ orientation to cross-cultural experiences. When workforces become culturally diverse, organizations should modify HRM practices to enable the full use of the range of skills and talents available from the diversity, and to ensure affective and behavioral costs are minimized. As globalization and international competition will continue to increase, organizations including those in the Asia-Pacific region, should seriously reevaluate their HRM policies to adapt and take advantage of an increasingly culturally diverse workforce.

Originality/value – The model provides a useful basis upon which organization researchers and practitioners can base their respective agendas.

Self assembled nanostructured complexes and blends via hydrogen bonding interactions

Small angle X-ray scattering (SAXS) is useful to explain the formation of microstructures and the mechanism of microphase separation in self-assembled blends and complexes. In our study, we have used SAXA to examine the ordered and disordered nanostructures as well as morphological transitions in block copolymer/homopolymer blends and complexes [1,2].

Improving the coordination of care for low back pain patients by creating better links between acute and community services

This paper reports on the development of a care-pathway to improve service linkages between the acute setting and community health services in the treatment of low back pain. The pathway was informed by two processes: (1) a literature review based on best-practice guidelines in the assessment, treatment and continuity of care for low back pain patients; and (2) consultation with staff and key stakeholders. Stakeholders from both the acute and community sectors comprised the Working Group, who identified central areas of concern to be addressed in the care-pathway, with the goal of preventing chronicity of low back pain and reducing emergency department presentations. The main outcomes achieved include: the development of a new care-coordinator role, which would support a greater focus on integration between acute and community sectors for low back pain patients; identifying the need to screen at-risk patients; implementation of the SCTT (Service Coordination Tool Templates) tool as a system of referral across the acute and community settings; and agreement on the need to develop an evidence-based self-management program to be offered to low back pain patients. The benefits and challenges of implementing this care pathway are discussed.

Microengineering of supramolecular soft materials by design of the crystalline fiber networks

Crystalline spherulitic fiber networks are commonly observed in polymeric and supramolecular functional materials. The elasticity of materials with this type of network is low if interactions between the individual spherulites are weak (mutually exclusive). Improving the elasticity of these materials is necessary because of their important applications in many fields. In this work, the engineering of the microstructures and rheological properties of this type of material is carried out. A small molecule organogel formed by the gelation of N-lauroyl-L-glutamic acid di-n-butylamide (GP-1) in propylene glycol (PG) is used as an example. The elasticity of this material is improved by controlling the thermodynamic driving force, the supersaturation of the gelator, and by using a selected copolymer additive to manipulate the primary nucleation of GP-1. Because of the weak interactions between the GP-1 spherulites, with the same fiber mass, the elasticity of GP-1/PG gel is less than half of those of the other two gels formed by GP-1 and 2-hydroxystearlic acid in solvent benzyl benzoate (BB), which are supported by interconnecting spherulitic fiber networks. This work develops a robust approach to the engineering of supramolecular functional materials especially those with mutually exclusive spherulite fiber networks.

A probabilistic approach to the anxious home for activity monitoring

This paper describes an approach to representing normal activities in a smart house based on the concept of anxiety. Anxiety is computed as a function of time and is kept low by interactions of an occupant with the various devices in a house. Abnormality is indicated by a lack of activity or the wrong activity which will cause anxiety to rise ultimately raising an alarm, querying the occupant and/or alerting a carer in real-time. Anxiety is formulated using probabilistic models that describe how people interact with devices in combinations. These models can be learnt interactively as the smart house acts pessimistically enquiring of the occupant if what they are doing is normal. Results are presented for a number of kitchen scenarios and for different formulations of anxiety.

2001 Volvo Award winner in clinical studies : effects of a media campaign on back pain beliefs and its potential influence on management of low back pain in general practice

Study Design. Quasi-experimental, nonrandomized, nonequivalent, parallel group-controlled study involving before and after telephone surveys of the general population and postal surveys of general practitioners was conducted, with an adjacent state used as a control group.


Objectives. To evaluate the effectiveness of a population-based intervention designed to alter beliefs about back pain, influence medical management, and reduce disability and workers’ compensation–related costs.


Summary of Background Data. A multimedia campaign begun during 1997 in Victoria, Australia, positively advised patients with back pain to stay active and exercise, not to rest for prolonged periods, and to remain at work.


Methods. The campaign’s impact on population beliefs about back pain and fear-avoidance beliefs was measured in telephone surveys, and the effect of the campaign on the potential management of low back pain by general practitioners was assessed by eliciting their likely approach to two hypothetical scenarios in mailed surveys. Demographically identical population groups in Victoria and the control state, New South Wales, were surveyed at three times: before, during, and after intervention in Victoria.


Results. The studies were completed by 4730 individuals in the general population and 2556 general practitioners. There were large statistically significant improvements in back pain beliefs over time in Victoria (mean scores on the Back Beliefs Questionnaire, 26.5, 28.4, and 29.7), but not in New South Wales (26.3, 26.2, and 26.3, respectively). Among those who reported back pain during the previous year, fear-avoidance beliefs about physical activity improved significantly in Victoria (mean scores on the Fear-Avoidance Beliefs Questionnaire for physical activity, 14, 12.5, and 11.6), but not in New South Wales (13.3, 13.6, and 12.7, respectively). General practitioners in Victoria reported significant improvements over time in beliefs about back pain management, as compared with their interstate colleagues. There were statistically significant interactions between state and time for 7 of 10 responses on management of acute low back pain, and for 6 of 10 responses on management of subacute low back pain.


Conclusion. A population-based strategy of providing positive messages about back pain improves the beliefs of the general population and general practitioners about back pain and appears to influence medical management.

Substrate-induced coagulation (SIC) of nano-disperse carbon black in non-aqueous media : a method of manufacturing highly conductive cathode materials for Li-ion batteries by self-assembly

Substrate-induced coagulation (SIC) is a coating process based on self-assembly for coating different surfaces with fine particulate materials. The particles are dispersed in a suitable solvent and the stability of the dispersion is adjusted by additives. When a surface, pre-treated with a flocculant e.g. a polyelectrolyte, is dipped into the dispersion, it induces coagulation resulting in the deposition of the particles on the surface. A non-aqueous SIC process for carbon coating is presented, which can be performed in polar, aprotic solvents such as N-Methyl-2- pyrrolidinone (NMP). Polyvinylalcohol (PVA) is used to condition the surface of substrates such as mica, copperfoil, silicon-wafers and lithiumcobalt oxide powder, a cathode material used for Li-ion batteries. The subsequent SIC carbon coating produces uniform layers on the substrates and causes the conductivity of lithiumcobalt oxide to increase drastically, while retaining a high percentage of active battery material.

Identity and self-presentation : from a representational to a performative lens in studying social media engagement in organisations

Social media make fast inroads into organisations. This raises issues regarding self-presentation and locating experts in these new emerging communication spaces, as the basis for effective social media-enabled knowledge work. However, research on self-presentation and identity in organisational social media is only just emerging and has been founded on broader understandings from studies of public social media. In this literature study we demonstrate that the existing body of research on identity in social media is dominated by a ‘representational lens’. Based on an analysis of the historic foundations of this stream of research, we will expose limitations of this lens in capturing contemporary engagement in online spaces and advocate for a ‘performative lens’ in studying identity work in organisations. We contribute a detailed exposition of the evolution of identity studies in the context of public social media, and we offer an alternative lens for studying the topic in organisational contexts.

What is the role of tobacco control advertising intensity and duration in reducing adolescent smoking prevalence? Findings from 16 years of tobacco control mass media advertising in Australia

ABSTRACT
Objective: To examine how the intensity and duration of tobacco control advertising relate to adolescent smoking prevalence.
Methods: Australian students (aged 12–17 years) participating in a national survey conducted triennially between 1993 and 2008 (sample size range 12 314–16 611). The outcome measure was students’ smoking in the previous 4 weeks collected through anonymous, self-completed surveys. For each student, monthly targeted rating points (TRPs, a measure of television advertising exposure) for tobacco control advertising was calculated for the 3 and 12 months prior to surveying. For each time period, cumulative TRPs exposure and exposure to three intensity levels (≥100 TRPs/month; ≥400 TRPs/month; ≥800 TRPs/month) over increasing durations (eg, 1 month, 2 months, etc) were calculated. Logistic regression examined associations between TRPs and adolescent smoking after controlling for demographic and policy variables.
Results: Past 3-month cumulative TRPs were found to have an inverse relationship with smoking prevalence. Low TRPs exposure in the past 12 months was positively associated with adolescent smoking prevalence. However, smoking prevalence reduced with cumulative exposure levels above 5800 cumulative TRPs. Additionally, exposure to ≥400 TRPs/month and ≥800 TRPs/month were associated with reduced likelihood of smoking, although the duration needed for this effect differed for the two intensity levels. When intensity was ≥400 TRPs/month, the odds of smoking only reduced with continuous exposure. When intensity was ≥800 TRPs/month, exposure at levels less than monthly was associated with reductions in smoking prevalence.
Conclusions: Both antismoking advertising intensity and duration are important for ensuring reductions in adolescent smoking prevalence.

Media/ting change: the print media's role in mediating education policy in a period of radical reform in Victoria, Australia

This paper draws upon critical discourse analysis, cultural studies and communication theory, studies on media and educational reform, and the work of Bernstein, Bourdieu and Luhmann in particular, to explore how the print and media 'mediated' a period of educational change marked by moves to self-management in schools in Victoria, Australia. It considers how the media was mobilized by various education stakeholders, and in turn informed relations between schools and government, through policy discourses and texts. It considers why and how particular themes became media 'issues', how schools and teachers responded to these issues, and how the media was used by various stakeholders in education to shape policy debates. It is based on a year-long qualitative study that explored critical incidents and representations about education in the print media over a year in the daily press. It illustrates the ways in which a neo-liberal Victorian government mobilized the media to gain strategic advantage to promote radical education reform policies, considers the media effects of this media/tion process on schools and teachers, and conceptualizes how school and system performance is fed from and into media representations, public perceptions and community understandings of schools and teachers' work.
