Evaluation of a stress management course in adult education centres in rural Australia

Objective: To investigate whether attending a six-week stress management course in a rural adult education centre is effective in reducing participants' levels of stress, anxiety and depression.

Design: Repeated measures design using self-report measures of stress, anxiety and depression at commencement and completion of a six-week stress management course, and six months post-completion follow up.

Setting and participants: One hundred and thirty-two adults (age range 18–73 years) living in a rural community who self-enrolled in the stress management course at adult education centres.

Intervention: The course consisted of six weekly group sessions. Each two-hour session conducted by mental health professionals, included teaching cognitive behavioural strategies targeted at reducing individual symptoms of stress.

Main outcome measures: Comparative analysis of pre- and post-test and six-month follow up on measures of stress (Stress Symptom Checklist), anxiety and depression (Hospital Anxiety and Depression Scale).

Results: Results indicated a significant reduction in stress symptoms (F(7,90) = 34.92, P < 0.001), anxiety and depression (F(3,95) = 87.92, P < 0.001) from course commencement to course completion. These improvements were sustained six months after course completion for stress symptoms (F(11,65) = 22.40, P < 0.001), anxiety and depression (F(5,73) = 41.78, P < 0.001).

Conclusion: Findings demonstrate the stress management course is an effective community intervention in a rural community. Challenges for future implementation of the program are discussed.

Dietary patterns throughout adult life are associated with body mass index, waist circumference, blood pressure, and red cell folate

Dietary patterns are important in the prevention of chronic disease; however, there are few studies that include repeat measures of dietary patterns. The objective of this study was to assess the relations between dietary patterns during adult life (at ages 36, 43, and 53 y) and risk factors for chronic disease at age 53 y. Participants of a longitudinal study of health completed a 5-d food diary at 3 occasions during adult life (n = 1265). Factor analysis was used to identify dietary patterns and a pattern score was calculated from the consumption of the food items in each dietary pattern. Means and 95% CI for dietary pattern scores were calculated for each risk factor category using random effects models adjusted for socio-demographic and health-related behaviors. In women, the fruit, vegetables, and dairy pattern was inversely associated with BMI (P < 0.004), waist circumference (P = 0.0007), blood pressure (P = 0.02), and was positively associated with red cell folate (P < 0.03). The ethnic foods and alcohol pattern was also inversely associated with blood pressure (P = 0.008), whereas the meat, potatoes and sweet foods pattern was positively associated with glycated hemoglobin (P = 0.01). In men, a mixed pattern was inversely associated with waist circumference (P = 0.02) and blood pressure (P = 0.01), whereas there were no significant associations with the ethnic foods and alcohol pattern. Specific dietary patterns throughout adult life were associated with chronic disease risk factors.

Sun exposure and sun protection behaviours among young adult sport competitors

Objective: To explore the relationship between sun protection and physical activity in young adults (18-30 years) involved in four organised sports.

Methods: Participants (n=237) in field hockey, soccer, tennis and surf sports completed a self-administered survey on demographic and sun-protective behaviours while playing sport. Differences in sun-protective behaviour were explored by sport and by gender.

Results: Sunburn during the previous sporting season was high (69%). There were differences between sports for sunburn, sunscreen use and reapplication of sunscreen. Lifesaving had the highest rates compared with the other three sports. Hats and sunglasses worn by participants varied significantly by sports. A greater proportion of soccer and hockey players indicated they were not allowed to wear a hat or sunglasses during competition. For all sports, competition was played mainly in the open with no shade provision for competitors while they were playing. There were some gender differences within each of the sports. Female soccer and tennis players were more likely to wear sunscreen compared with males. Female hockey players were more likely to wear a hat compared with males.

Conclusions: Our findings highlight that there is still room for improvement in sun-protective behaviours among young adult sport competitors. There is a need for a systematic approach to sun protection in the sporting environments of young adults.

Implications: Health promotion efforts to increase physical activity need to be paired with sun protection messages.

Media influences on attitudes and perceptions toward the body among adult men and women

The current study investigated media influences on men's and women's body perception. Participants were 60 men and 60 women. Men overestimated their chest, waist, and thighs and underestimated their hips. Women overestimated the size of all body parts. Men's and women's perception of their body was not predicted by media exposure or attitudes to the media. Both men's and women's ideal body was different from their current bodies. Attitudes and exposure to the media predicted men's (but not women's) perceptions of the ideal body held by the media, as well as both men's and women's ideal chest and waist. These findings suggest that the media has an impact on the ideal body size of both men and women.

Flexible delivery in the Australian vocational education and training sector: Barrier to success identified in cases studies of four adult learners

Government policy in Australia is increasingly encouraging training organisations in the Vocational Education and Training (VET) sector to adopt flexible delivery approaches, but some researchers are sounding a note of caution. Evidence is emerging that Australian VET learners are not universally ready for flexible delivery, and this is reflected in high attrition rates and low pass rates. The literature on flexible delivery identifies a number of specific factors that can impact on the success of adult learners. However, there seems to be agreement that failure or dropout is not determined by a single factor, but by the interaction of a number of factors that build up over time. To understand these factors, we need to understand the learners - what their participation in education means to them, the context in which they are studying, and the numerous inter-connected factors that contribute to their failure to achieve a successful outcome. This paper discusses four case studies from a research project that followed up a small number of adult learners who enrolled in flexible delivery VET courses but did not achieve a successful outcome.

Hierarchical relationship between values, lifestyles, possessions and food consumption among Beijing adult population

A representative sample (N=801) of the Beijing adult population was used to empirically test and validate a proposed hierarchical model of relationships between values, lifestyles, possessions and food consumption. The theoretical contribution of the present study is the development and an empirically supported paradigm, which explains consumers' consumption behaviour. A further outcome is the substantiation of a pathway model involving hierarchical relationship between values, lifestyle, and demographic variables on material possessions and food consumption.

Immunolocalization of Na+/K+-ATPase, carbonic anhydrase II, and vacuolar H+-ATPase in the gills of freshwater adult lampreys, Geotria australis

As adults, anadromous lampreys migrate from seawater into freshwater rivers, where they require branchial ion (NaCl) absorption for osmoregulation. In teleosts and elasmobranchs, pharmological, immunohistochemical, and molecular data support roles for Na⁺/K⁺-ATPase (NPPase), carbonic anhydrase II (CAII), and vacuolar H⁺-ATPase (V-ATPase) in two different models of branchial ion absorption. To our knowledge, these transport-related proteins have not been studied in adult freshwater lampreys, and therefore it is not known if they are expressed, or have similar functions, in lampreys. The purpose of this study was to localize NPPase, CAII, and V-ATPase in the gills of adult freshwater lampreys and determine if any of these transport-related proteins are expressed in the same cells. Heterologous antibodies were used to localize the three proteins in gill tissue from pouched lamprey (Geotria australis). Immunoreactivity (IR) for all three proteins occurred between, and at the base of, lamellae in cells that match previous descriptions of mitochondrion-rich-cells (MRCs). NPPase-IR was always on the basolateral side of cells that did not stain for CAII or V-ATPase. In contrast, CAII-IR was always on the apical side of cells that also contained diffuse V-ATPase-IR. Therefore, we have identified two types of MRC in adult freshwater lamprey gills based on immunohistochemical staining for three transport proteins. A model of ion transport, based on our results, is proposed for adult freshwater lampreys. 

Measuring Ultrasonic Communication Between Mouse Pups and Adult Mother Mice

Measuring ultrasonic communication provides us with a way to study parental influence on animals. In this study I measured the ultrasonic communication between mouse pups and two maternal females, one of which who had given birth to the pups and the other had raised them. I found that there was no significant difference between the amount of noise expressed by pups in response to each the biological mother and foster mother test groups. Mouse pups call to maternal females regardless of genetic relatedness. Communication in mice may be a more complicated model because of their communal nature.

Socio-demographic variations in walking for transport for recreation or exercise among adult Australians.

Background: Walking is integral to strategies to promote physical activity. We identified socio-demographic variations in walking for transport, and for recreation or exercise. Methods: Representative population data (n = 3392) from Australia were collected using computer assisted telephone interviewing, to examine adults’ participation in moderate- or brisk-paced walking for transport and walking for recreation or exercise; walking “sufficient” to meet the current public health guideline (> 150 min/wk); and, the contributions of total walking to meeting the guideline for total physical activity. Results: Rates of sufficient walking for transport (10% for men, 9% for women) were lower than those for walking for recreation or exercise (14% for both genders). Few socio-demographic differences emerged. Men over age 60 y were significantly less likely (OR = 0.40) to walk for transport; men age 45 to 59 y were more likely (OR = 1.56) to walk for recreation or exercise. Walking contributed more toward meeting the current public health guideline among women (15% to 21%) than among men (6% to 8%). Conclusions: There is potential for socially equitable increases in participation, through a focus on both walking for transport and on walking for recreation or exercise; attention to gender differences would be helpful.

Morphologic and functional characterization of granulocytes and macrophages in embryonic and adult zebrafish.

The zebrafish is a useful model organism for developmental and genetic studies. The morphology and function of zebrafish myeloid cells were characterized. Adult zebrafish contain 2 distinct granulocytes, a heterophil and a rarer eosinophil, both of which circulate and are generated in the kidney, the adult hematopoietic organ. Heterophils show strong histochemical myeloperoxidasic activity, although weaker peroxidase activity was observed under some conditions in eosinophils and erythrocytes. Embryonic zebrafish have circulating immature heterophils by 48 hours after fertilization (hpf). A zebrafish myeloperoxidase homologue (myeloid-specific peroxidase; mpx) was isolated. Phylogenetic analysis suggested it represented a gene ancestral to the mammalian myeloperoxidase gene family. It was expressed in adult granulocytes and in embryos from 18 hpf, first diffusely in the axial intermediate cell mass and then discretely in a dispersed cell population. Comparison of hemoglobinized cell distribution, mpx gene expression, and myeloperoxidase histochemistry in wild-type and mutant embryos confirmed that the latter reliably identified a population of myeloid cells. Studies in embryos after tail transection demonstrated that mpx- and peroxidase-expressing cells were mobile and localized to a site of inflammation, indicating functional capability of these embryonic granulocytes. Embryonic macrophages removed carbon particles from the circulation by phagocytosis. Collectively, these observations have demonstrated the early onset of zebrafish granulopoiesis, have proved that granulocytes circulate by 48 hpf, and have demonstrated the functional activity of embryonic granulocytes and macrophages. These observations will facilitate the application of this genetically tractable organism to the study of myelopoiesis.

Variable definitions: implications for the prediction of pulmonary complications after adult cardiac surgery

Aim: The aim of this paper was to review the implications that variable definitions have for the prediction of post-operative pulmonary complications after cardiac surgery.

Method: A review of the literature from 1980 to 2002. Selected studies demonstrated an original attempt to examine multivariate associations between pre, intra or post-operative antecedents and pulmonary outcomes in patients undergoing coronary artery bypass grafting (CABG). Reports that described the validation of established clinical prediction rules, testing interventions or research conducted in non-human cohorts were excluded from this review.

Results: Consistently, variable factor and outcome definitions are combined for the development of multivariate prediction models that subsequently have limited clinical value. Despite being prevalent there are very few attempts to examine post-operative pulmonary complications (PPC) as endpoints in isolation. The trajectory of pulmonary dysfunction that precedes complications in the post-operative context is not clear. As such there is little knowledge of post-operative antecedents to PPC that are invariably excluded from model development.

Conclusion: Multivariate clinical prediction rules that incorporate antecedent patient and process factors from the continuum of cardiovascular care for specific pulmonary outcomes are recommended. Models such as these would be useful for practice, policy and quality improvement.

Teacher or trainer? The shaping of teacher identity in adult education contexts

In response to changing government funding priorities there has been a shift away from the provision of needs based language and personal development courses for adults in community based contexts towards the delivery of vocational education. Much vocational education is characterized by competency-based curriculum and outcomes influenced by the needs of the current labour market as well as economic driven initiatives such as competitive tendering for short-term course funding. These trends have resulted in changes to the nature of curriculum, assessment, and the purpose and nature of the delivery of courses to adult learners. In turn, these changes affect the ways in which teachers see themselves and carry out their roles as professionals. This paper explores the ways in which the current discourses of vocational education shape teacher identities across a variety of vocational education contexts and the ways in which teacher identities are played out through training and teaching practices.
