Disrupted fine-scale population processes in fragmented landscapes despite large-scale genetic connectivity for a widespread and common cooperative breeder : the superb fairy-wren (Malurus cyaneus)

Understanding how habitat fragmentation affects population processes (e.g. dispersal) at different spatial scales is of critical importance to conservation. We assessed the effects of habitat fragmentation on dispersal and regional and fine-scale population structure in a currently widespread and common cooperatively breeding bird species found across south-eastern Australia, the superb fairy-wren Malurus cyaneus. Despite its relative abundance and classification as an urban tolerant species, the superb fairy-wren has declined disproportionately from low tree-cover agricultural landscapes across the Box-Ironbark region of north-central Victoria, Australia. Loss of genetic connectivity and disruption to its complex social system may be associated with the decline of this species from apparently suitable habitat in landscapes with low levels of tree cover. To assess whether reduced structural connectivity has had negative consequences for genetic connectivity in the superb fairy-wren, we used a landscape-scale approach to compare patterns of genetic diversity and gene flow at large (landscape/regional) and fine (site-level) spatial scales. In addition, using genetic distances, for each sex, we tested landscape models of decreased dispersal through treeless areas (isolation-by-resistance) while controlling for the effect of isolation-by-distance. Landscape models indicated that larger-scale gene flow across the Box-Ironbark region was constrained by distance rather than by lack of structural connectivity. Nonetheless, a pattern of isolation-by-resistance for males (the less-dispersive sex) and lower genetic diversity and higher genetic similarity within sites in low-cover fragmented landscapes indicated disruption to fine-scale gene flow mechanisms and/or mating systems. Although loss of structural connectivity did not appear to impede gene flow at larger spatial scales, fragmentation appeared to affect fine-scale population processes (e.g. local gene flow mechanisms and/or mating systems) adversely and may contribute to the decline of superb fairy-wrens in fragmented landscapes in the Box-Ironbark region. © 2012 British Ecological Society.

Alcohol consumption, obesity, and psychological distress in farming communities — an Australian study

Purpose: Alcohol consumption patterns nationally and internationally have been identified as elevated in rural and remote populations. In the general Australian population, 20.5% of adult males and 16.9% of adult females drink at short-term, high-risk levels. Farmers are more likely to drink excessively than those living in major cities. This study seeks to explore the relationships between farmers’ physical and mental health and their alcohol consumption patterns. Our hypothesis is that farmers consume alcohol at high-risk levels more often than the Australian average and that this consumption is associated with obesity and psychological distress.

Methods: Cross-sectional descriptive data were collected within Australian farming communities from 1,792 consenting adults in 97 locations across Australia. Data on anthropometric measurements, general physical attributes and biochemical assessments were used to explore the interrelationships of self-reported alcohol consumption patterns with obesity, psychological distress, and other physical health parameters.

Findings: There was a higher prevalence of short-term, high-risk alcohol consumption (56.9% in men and 27.5% in women) reported in the study compared with national data. There was also a significant positive association between the prevalence of high-risk alcohol consumption and the prevalence of obesity and abdominal adiposity in psychologically distressed participants.

Conclusions: The prevalence of short-term, high-risk alcohol consumption practices in this cohort of farming men and women is significantly higher than the Australian average. These consumption practices are coupled with a range of other measurable health issues within the farming population, such as obesity, hypertension, psychological distress, and age.

A protocol for advanced psychometric assessment of surveys

Background and Purpose. In this paper, we present a protocol for advanced psychometric assessments of surveys based on the Standards for Educational and Psychological Testing. We use the Alberta Context Tool (ACT) as an exemplar survey to which this protocol can be applied.

Methods. Data mapping, acceptability, reliability, and validity are addressed. Acceptability is assessed with missing data frequencies and the time required to complete the survey. Reliability is assessed with internal consistency coefficients and information functions. A unitary approach to validity consisting of accumulating evidence based on instrument content, response processes, internal structure, and relations to other variables is taken. We also address assessing performance of survey data when aggregated to higher levels (e.g., nursing unit).

Discussion. In this paper we present a protocol for advanced psychometric assessment of survey data using the Alberta Context Tool (ACT) as an exemplar survey; application of the protocol to the ACT survey is underway. Psychometric assessment of any survey is essential to obtaining reliable and valid research findings. This protocol can be adapted for use with any nursing survey.

Zombie processes and undead technologies

Zombies in the Academy taps into the current popular fascination with zombies and brings together scholars from a range of fields, including cultural and communication studies, sociology, film studies, and education, to give a critical account of the political, cultural, and pedagogical state of the university through the metaphor of zombiedom. The contributions to this volume argue that the increasing corporatization of the academy—an environment emphasizing publication, narrow research, and the vulnerability of the tenure system— is creating a crisis in higher education best understood through the language of zombie culture—the undead, contagion, and plague, among others. Zombies in the Academy presents essays from a variety of scholars and creative writers who present an engaging and entertaining appeal for serious recognition of the conditions of contemporary humanities teaching, culture, and labor practices.

A comparison of the psychological outcomes of cosmetic surgical procedures

Studies of psychological outcomes of cosmetic surgery generally provide low standards of evidence due to significant methodological limitations and few studies have explored the outcomes of surgery types other than breast reduction or have compared post-operative outcomes for different surgery types. This study therefore aimed to explore the psychological outcomes and post-operative satisfaction of cosmetic surgery and compare the outcomes and satisfaction of participants undergoing different procedures.

Surveys were administered to a sample of 142 elective cosmetic surgery patients prior to surgery and six months after surgery. The surveys included standardised measures of body image (appearance evaluation, appearance orientation, body areas satisfaction), self-esteem, and mental health (psychiatric disturbance, anxiety, depression, dysmorphic concerns).

The findings revealed high rates of post-operative satisfaction and significant improvements in several dimensions of body image (appearance evaluation and body area satisfaction) and mental health (anxiety, depression, and dysmorphic concerns), but not self-esteem. Breast augmentation patients reported significantly higher improvement on appearance evaluation, significantly higher ratings of how likely they thought it was that they had achieved, or would achieve, what they were looking for in having the procedure, and a trend to report that the overall result of surgery was better than or as expected than rhinoplasty patients.

It is recommended that future research clarifies the degree to which self-esteem and indices of mental health improve after cosmetic surgery and fully establishes the impact of different procedures on psychological outcomes.

Associations between psychological stress, eating, physical activity, sedentary behaviours and body weight among women: a longitudinal study

Background: 

Symbolic interactions and the development of women leaders in higher education

The under-representation of women in higher education (HE) leadership is a persistent global phenomenon. The purpose of this research is to re-examine this issue through symbolic interactionism (SI). Eight women aspiring to leadership were invited to participate in semi-structured interviews after attending a leadership programme specifically designed to enhance their leadership prospects. Analysis indicated ambiguities and contradictions that surround notions of leadership, in particular how the participants position themselves and are positioned in their workplace. This was evidenced by the meaning they attributed to: recognizing a leader; interactions with existing leadership; and speculation regarding their leadership capacity. Gendered notions were apparent in their constructed meanings. Similarity attraction was also evident, with men being observed as ‘paying it forward’, therefore facilitating promotion. Formal leadership training was advocated rather than experiential processes.

The effect of physical activity on psychological distress, cortisol and obesity: results of the farming fit intervention program

Background:
Rural and regional Australians have a higher likelihood of mental illness throughout their lifetime than people living in major cities, although the underlying reasons are not yet well defined. Additionally, rural populations experience more lifestyle associated co-morbidities including obesity, diabetes and cardiovascular disease. Research conducted by the National Centre for Farmer Health between 2004 and 2009 revealed a positive correlation between obesity and psychological distress among the farming community. Chronic stress is known to overstimulate the regulation of the hypothalamic-pituitary-adrenal (HPA) axis and cortisol secretion which are associated with abdominal adiposity. Increasing physical activity may normalise cortisol secretion and thereby positively impact both physical and mental health. This paper assesses the effects of increasing physical activity on obesity, health behaviors and mental health in Victorian farming men and women.

Methods:
Farming Fit was a six month quasi-experimental (convenience sample) longitudinal design control-intervention study. Overweight or obese (BMI ?25?kg/m2) farm men (n?=?43) and women (n?=?29) were recruited with demographic, health behaviors, anthropometric, blood pressure and biochemistry data collected at baseline and at a six months. Salivary cortisol and depression anxiety stress scale results were collected at baseline, three and six months. The intervention group (n?=?37) received a personalized exercise program and regular phone coaching to promote physical activity.

Results:
The intervention group showed significant reductions in body weight and waist circumference. Results indicated that following the six month exercise program, the intervention group were 2.64???0.65?kg lighter (p?<?0.001), had reduced waist circumference by 2.01???0.86?cm (p?=?0.02) and BMI by 0.97???0.22?kg/m2 (p?<?0.001) relative to the control group.

Conclusion:
Increasing physical activity altered measures of obesity in farm men and women but did not affect mental health measures or cortisol secretion levels.

Stressors, Recovery Processes, and Manifestations of Training Distress in Dance

Abstract
Dancers are expected to maintain consistently high levels of performance capability and to perform on demand. To meet these expectations, they subject their bodies to long hours of intensive physical training. Such training regimens are often combined with tight rehearsal and performance schedules, which over time, can lead to persistent fatigue, psychological distress, performance decrements, and injury. A similar process has been observed as a consequence of high-intensity training in many different sports, and considerable sport-related research has been devoted to identifying the antecedents, the symptoms that are experienced, and the most cost-effective ways of monitoring symptom development. This paper presents a general heuristic framework for understanding this “training distress process” and discusses the framework with specific reference to dance.

External policy influence and higher education reform in Ethiopia : understanding symbolic power of the World Bank

Increasingly national policy processes are intersected with and affected by global policy actors and ideas. In aid-recipient countries such as Ethiopia, donors use financial and non-financial means to influence national policy decisions and directions. This paper is about the non-financial influence of the World Bank (WB) in the Ethiopian higher education policy reform. Using Pierre Bourdieu’s concept of symbolic power as a ‘thinking tool’, the paper aims to shed light on forms of symbolic capital that the Bank uses to generate a ‘misrecognisable’ form of power that regulates the HE policy process in Ethiopia. The findings show that the WB transforms its symbolic capital of recognition and legitimacy to establish a ‘shared misrecognition’ and thereby make its policy prescriptions implicit and hence acceptable to local policy agents. The Bank uses knowledge-based regulatory instruments to induce compliance to its neoliberal policy prescriptions. The paper therefore underscores the value of symbol power as an analytical framework to understand elusive but critical role of donors in policy processes of aid recipient countries.

A qualitative evaluation of online chat groups for women completing a psychological intervention for female sexual dysfunction

Because of the embarrassment that can surround female sexual dysfunctions, online interventions offer an anonymous and private treatment alternative. Recently, an online cognitive-behavioral treatment for female sexual dysfunctions was evaluated. Although significant improvements were observed in sexual functioning, the treatment was primarily a behavioral intervention because of difficulties with engaging participants in cognitive therapy over e-mail. To address this limitation, the use of chat groups was incorporated into a new online treatment for female sexual dysfunctions—the PursuingPleasure program. Thirty-eight women participated in the PursuingPleasure chat groups. The goals of the chat groups were to address and overcome challenges as women progressed through PursuingPleasure and to create a social support network where group therapy processes could be used. The chat groups aimed to address misunderstandings, monitor changes, and receive feedback. A qualitative analysis of the chat groups revealed that they helped to facilitate the cognitive-affective aspects of the program, as well as fulfill their other intended functions. This study demonstrates how the use of chat groups in the online treatment of female sexual dysfunctions is a useful addition to Internet-based treatment. Feedback suggests that the chat groups were one of the most helpful aspects of the program, although a small group of women reported finding the groups unhelpful.

Failure to thrive: mid-career women in higher education

Gender underrepresentation in higher education (HE) is a persistent global phenomenon. The purpose of this research was to re-examine it through symbolic interactionism (SI). Eight women aspiring to leadership were invited to participate in semi structured interviews after attending a leadership programme specifically designed to enhance their prospects. Analysis indicated ambiguities and contradictions surround notions of leadership, as well as opportunities for leadership. This was evidenced by their appraisal of the existing leadership, speculations regarding their leadership capacity, how the participants position themselves and are positioned in their workplace. Actively “paying it forward” was seen as facilitating promotion, and line managers’ familiarity with the work undertaken by aspirants. Formal leadership training was advocated rather than experiential processes. 

Physiological responses to psychological stress: importance of adiposity in men aged 50-70 years

We tested the hypothesis that overweight/obese men aged 50–70 years will have a greater salivary cortisol, salivary alpha amylase and heart rate (HR) responses to psychological stress compared with age matched lean men. Lean (BMIZ20–25 kg/m2; nZ19) and overweight/obese (BMIZ27–35 kg/m2; nZ17) men (50–70 years) were subjected to a well-characterised psychological stress (Trier Social Stress Test, TSST) at 1500 h. Concentrations of cortisol and alpha amylase were measured in saliva samples collected every 7–15 min from 1400 to 1700 h. HR was recorded using electrocardiogram. Body weight, BMI, percentage body fat, resting systolic and diastolic blood pressure and mean arterial pressure were significantly higher (P!0.05) in overweight/obese men compared with lean men. Both groups responded to the TSST with a substantial elevation in salivary cortisol (372%), salivary alpha amylase (123%) and HR (22%). These responses did not differ significantly between the groups (time!treatment interaction for salivary cortisol, salivary alpha amylase and HR; PZ0.187, PZ0.288, PZ0.550, respectively). There were no significant differences between the groups for pretreatment values, peak height, difference between pretreatment values and peak height (reactivity) or area under the curve for salivary cortisol, salivary alpha amylase or HR (PO0.05 for all). The results showed that, for men with a moderate level of overweight/obesity who were otherwise healthy, the response of salivary cortisol, salivary alpha amylase and HR to acute psychological stress was not impaired.

Indigenous students' persistence in higher education in Australia: contextualising models of change from psychology to understand and aid students' practices at a cultural interface

The need to address the substantial inequities that exist between Indigenous and non-Indigenous Australians in higher education is widely recognised. Those factors that affect the performance of Indigenous students in tertiary education have been reasonably well documented across different institutions, disciplines, and programme levels but there has, to date, been less consideration of the processes by which Indigenous students either persist or desist in higher education. This paper aims to present a conceptual understanding of academic persistence that can inform the delivery of tailored academic support interventions to Indigenous students who are at high risk of leaving higher education.
