Predicting the consumption of foods low in saturated fats among people diagnosed with Type 2 diabetes and cardiovascular disease: the role of planning in the theory of planned behaviour

The present study tested the utility of an extended version of the theory of planned behaviour that included a measure of planning, in the prediction of eating foods low in saturated fats among adults diagnosed with Type 2 diabetes and/or cardiovascular disease Participants (N = 184) completed questionnaires assessing standard theory of planned behaviour measures (attitude, subjective norm, and perceived behavioural control) and the additional volitional variable of planning in relation to eating foods low in saturated fats Self-report consumption of foods low insaturated fats was assessed 1 month later In partial support of the theory of planned behaviour, results indicated that attitude and subjective norm predicted intentions to eat foods low in saturated fats and intentions and perceived behavioural control predicted the consumption of foods low in saturated fats As an additional variable, planning predicted the consumption of foods low in saturated fats directly and also mediated the intention-behaviour and perceived behavioural control-behaviour relationships, suggesting an important role for planning as a post-intentional construct determining healthy eating choices. Suggestions are offered for interventions designed to improve adherence to healthy eating recommendations for people diagnosed with these chronic conditions with a specific emphasis on the steps and activities that are required to promote a healthier lifestyle.

Behavioral, Normative and Control Beliefs Underlying Low-Fat Dietary and Regular Physical Activity Behaviors for Adults Diagnosed with Type 2 Diabetes and/or Cardiovascular Disease

Promoting healthy lifestyle behaviors is an important aspect of interventions designed to improve the management of chronic diseases such as Type 2 diabetes and cardiovascular disease. The present study used Ajzen’s (1991) theory of planned behavior as a framework to examine beliefs amongst adults diagnosed with these conditions who do and do not engage in low-fat dietary and regular physical activity behaviors. Participants (N = 192) completed a questionnaire assessing their behavioral, normative and control beliefs in relation to regular, moderate physical activity and eating foods low in saturated fats. Measures of self-reported behavior were also examined. The findings revealed that, in general, it is the underlying behavioral beliefs that are important determinants for both physical activity and low-fat food consumption with some evidence to suggest that pressure from significant others is an important consideration for low-fat food consumption. Laziness, as a barrier to engaging in physical activity, also emerged as an important factor. To encourage a healthy lifestyle amongst this population, interventions should address the perceived costs associated with behavioral performance and encourage people to maintain healthy behaviors in light of these costs

Control perception and its role in stress appraisal and coping : a study in work-related stress : a thesis presented in partial fulfilment of the requirements for the degree of Doctor of Philosophy at Massey University

Psychological theories view control as integral to emotional well-being and consequently this concept has played a prominent role in stress theories. In the transactional theory of stress control plays an important role in stressor appraisal where it is proposed to influence coping behaviour and coping effectiveness. However, little attention has been paid to the measurement of this important concept. This study adopts the transactional model to examine work-related stress and a major objective of the study is the development of a robust measure of situational control. It is argued that such a measure can not be merely reduced to a simple assessment that an individual either has or does not have control over a given situation, rather, it is important to identify the factors over which an individual strives to have control, as well as the degree of control over these factors that they perceive themselves to have. A pilot study was used to develop a 35 item scale for measuring situational control. The scale was then used in a survey of work-related stress that was administered to 134 employees in four departments of New Zealand government. Principal component analysis revealed that control perception is a multifaceted concept, and four facets representing predictability, task control, self control and general control were identified. Using these scales the study investigated the role that control plays in predicting coping behaviour and coping effectiveness. Through a series of moderated multiple regression analyses, control was examined as a moderator in the relationship between stress appraisal and coping behaviour. This analysis showed that perceptions of control are associated with problem-focused coping. This result is consistent with other studies and suggests that a greater perception of general control in the workplace is associated with greater use of problem-focused coping. However, the literature is more equivocal on the relationship between control perception and emotion-focused coping. The study found a significant interaction between self control and primary appraisal in predicting emotion-focused coping. In addition to this, situational threat was found to have a significant main effect on emotion-focused coping. The study also examined the influence of control perception and coping behaviour as predictors of perceived coping effectiveness, as proposed by the goodness of fit hypothesis. No evidence was found to support this hypothesis, although coping behaviour and control were both found to have main effects in predicting coping effectiveness

Working from home: do formal or informal telework arrangements provide better work-family outcomes?

Telework arrangements include a suite of options that workplaces provide to meet the growing demand for greater work flexibility and as a strategy to promote work-family balance. However, there has been minimal research comparing formal versus informal telework arrangements, and how they might support employees to manage the competing demands of work and family life. In this paper, we examine how formal and informal telework arrangements impact on public sector employees' job satisfaction, time spent on childcare, and satisfaction with the distribution of childcare tasks. We use survey data from public service employees who had access to telework entitlements in Queensland, Australia (n=856). Our analyses showed that formal and informal telework arrangements provide different outcomes to employed women and men with children, particularly in the areas of job satisfaction and satisfaction with the distribution of childcare tasks. These distinctions suggest that it is important for workplaces to consider how the type of telework arrangement offered can affect how successfully and equitably work-family outcomes are achieved

Control and Insecurity in Australian and Canadian Universities during the COVID-19 Pandemic

This study examines how the COVID-19 pandemic and ensuing university management control strategies have influenced higher education workers’ job security, stress and happiness. The primary quantitative and qualitative data are drawn from a survey of fourteen universities across Australia and Canada, supplemented by secondary research. The analysis examines institutional and worker responses to the pandemic, and resulting conflict over financial control at the macro (sector), meso (university) and micro (individual) levels.At the macro level, university responses were shaped by public policy decisions at both national and subnational layers of the state, and the higher education sector in both countries had a distinctly neoliberal form. However, Australian universities were exposed to greater financial pressure to cut job positions, and Australian university management might have been more inclined to do so than Canadian universities overall. Different institutional support for unionism at the macro level influenced how university staff were affected at the meso and micro levels. Restructuring at the universities across both countries negatively impacted job security and career prospects, in turn leading to reduced job satisfaction and increased stress. Although working from home was novel and liberating for many professional staff, it was a negative experience for many academic staff.Our analysis demonstrates that the experiences of university staff were influenced by more than the work arrangements implemented by universities during the COVID-19 pandemic. The approaches of universities to job protection, restructuring and engagement with staff through unions appeared to influence staff satisfaction, stress and happiness.Our findings extend the literature that documents how university staff routinely challenge neoliberalization processes in a variety of individual and collective actions, particularly in times of crisis. We argue that theorization of struggles over control of labour should be extended to account for struggles over control of finance.AbstractWe studied 14 universities across Canada and Australia to examine how the COVID-19 crisis, mediated through management strategies and conflict over financial control in higher education, influenced workers’ job security and affective outcomes like stress and happiness. The countries differed in their institutional frameworks, their union density, their embeddedness in neoliberalism and their negotiation patterns. Management strategies also differed between universities. Employee outcomes were influenced by differences in union involvement. Labour cost reductions negotiated with unions could improve financial outcomes, but, even in a crisis, management might not be willing to forego absolute control over finance, and it was not the depth of the crisis that shaped management decisions.Cette étude examine comment la pandémie de COVID-19 et les stratégies mises en oeuvre par la gestion universitaire ont influencé la sécurité d'emploi, le stress et le bonheur des travailleurs de l'enseignement supérieur. Les données quantitatives et qualitatives primaires proviennent d'une enquête menée dans quatorze universités en Australie et au Canada, complétée par des recherches secondaires. L'analyse examine les réponses des institutions et des travailleurs à la pandémie, ainsi que les conflits qui en résultent en matière de contrôle financier et ce, tant aux niveaux macro (secteur), méso (université) et micro (individu).Au niveau macro, les réponses des universités ont été façonnées par les politiques publiques de l'État aux niveaux national et infranational. Dans les deux pays l’approche avait une forme nettement " néolibérale ". Toutefois, les universités australiennes ont été davantage exposées à la pression financière en faveur des suppressions d'emplois, et la direction de ces universités a peut-être été plus encline à procéder à des mises à pied que l'ensemble des universités canadiennes. Les différences au niveau du soutien institutionnel au syndicalisme au niveau macro ont influencé la manière dont le personnel universitaire a été affecté aux niveaux méso et micro. La restructuration des universités, dans les deux pays, a eu un impact négatif sur la sécurité d'emploi et les perspectives de carrière, ce qui a entraîné une diminution de la satisfaction professionnelle et une augmentation du stress. Pour de nombreux membres du personnel professionnel, le travail à domicile était nouveau et libérateur, tandis que pour d’autres membres du personnel universitaire, le travail à domicile était une expérience négative.Notre analyse démontre que les expériences du personnel universitaire ont été influencées par d'autres facteurs que les modalités de travail mises en place par les universités pendant la pandémie de COVID-19. Les approches des universités en matière de protection de l'emploi, de restructuration et d'engagement avec le personnel par le biais des syndicats semblent influencer la satisfaction, le stress et le bonheur du personnel.Nos résultats s'inscrivent dans le prolongement de la littérature qui documente la manière dont les processus de néolibéralisation sont régulièrement contestés par le personnel universitaire dans le cadre de diverses actions individuelles et collectives, en particulier en temps de crise. Nous soutenons que la théorisation des luttes pour le contrôle du travail devrait être étendue aux luttes pour le contrôle des finances

Sustained knowledge work and thinking time amongst academics: gender and working from home during the COVID-19 pandemic

The COVID-19 pandemic triggered a migration of workforces to work from home. A key issue for academics was the implications for the ability to carve out ‘thinking time’ to engage in what we term sustained knowledge work, the type of work essential for producing research. We administered an employee survey to academics from seven Australian and seven Canadian Universities, receiving over 3000 responses. We report on both quantitative and qualitative findings from the survey, with a particular emphasis on the latter. The two countries displayed broadly similar patterns in responses, but these patterns were gendered in specific ways. We distinguished between episodic and sustained knowledge work and found the shift of the location for sustained knowledge work from the workplace to the home affected academics unevenly, with disproportionate negative impacts on women. There are implications for all knowledge workers: while gendered, domestic norms continue to exist, the sustained knowledge work that is critical to career advancement can become especially problematic for women knowledge workers

Functional roles of abdominal and back muscles during isometric axial rotation of the trunk

Electromyographic (EMG) studies have shown that a large number of trunk muscles are recruited during axial rotation. The functional roles of these trunk muscles in axial rotation are multiple and have not been well investigated. In addition, there is no information on the coupling torque at different exertion levels during axial rotation. The aim of the study was to investigate the functional roles of rectus abdominis. external oblique. internal oblique, latissimus dorsi, iliocostalis lumborum and multifidus during isometric right and left axial rotation at 100%, 70%, 50% and 30% maximum voluntary contractions (MVC) in a standing position. The coupling torques in sagittal and coronal planes were measured during axial rotation to examine the coupling nature of torque at different levels of exertions. Results showed that the coupled sagittal torque switches from nil to flexion at maximum exertion of axial rotation. Generally, higher EMG activities were shown at higher exertion levels for all the trunk muscles. Significant differences in activity between the right and left axial rotation exertions were demonstrated in external oblique, internal oblique, latissimus dorsi and iliocostalis lumborum while no difference was shown in rectus abdominis and multifidus. These results demonstrated the different functional roles of trunk muscles during axial rotation. This is important considering that the abdominal and back muscles not only produce torque but also maintain the spinal posture and stability during axial rotation exertions. The changing coupling torque direction in the sagittal plane when submaximal to maximal exertions were compared may indicate the complex nature of the kinetic coupling of trunk muscles.
