In the last two decades there has been a plethora of research on a range of subjects collectively and rhetorically known as ‘work-life balance’. The bulk of this research, which spans disciplines including feminist sociology, industrial relations and management, has focused on the significant concerns of employed women and/or dual career couples. Less attention has been devoted to scholarship which explicitly examines men and masculinities in this context. Meanwhile, public and organizational discourse is largely espoused in gender neutral terms, often neglecting salient gendered issues which differentially impact the ability of women and men to successfully integrate their work and non-work lives. This edited book brings together empirical studies of the work-life nexus with a specific focus on men’s working time arrangements, how men navigate and traverse paid work and family commitments, and the impact of public and organizational policies on men’s participation in work, leisure, and other life domains. The book is innovative in that it presents both macro (institutional, how policy affects practice) and micro (individual, from men’s own perspectives) level studies, allowing for a rich and contrasting exploration of how men’s participation in paid work and other domains is divided, conflicted, or integrated. The essays in this volume address issues of fundamental social, labor market, and economic change which have occurred over the last 20 years and which have profoundly affected the way work, care, leisure and community have evolved in different contexts. Taking an international focus, Men, Wage Work and Family contrasts various public and organizational policies and how these policies impact men’s opportunities and participation in paid work and non-work domains in industrialised countries in Europe, North America, and Australia.

This book investigates efforts by fathers’ rights groups to undermine battered women’s shelters and services, in the context of the backlash against feminism. Dragiewicz examines the lawsuit Booth v. Hvass, in which fathers’ rights groups attempted to use an Equal Protection claim to argue that funding emergency services that target battered women is discriminatory against men. As Dragiewicz shows, this case (which was eventually dismissed) is relevant to widespread efforts to promote a degendered understanding of violence against women in order to eradicate policies and programs that were designed to ameliorate harm to battered women.

Background: The regulation of plasminogen activation is a key element in controlling proteolytic events in the extracellular matrix. Our previous studies had demonstrated that in inflamed gingival tissues, tissue-type plasminogen activator (t-PA) is significantly increased in the extracellular matrix of the connective tissue and that interleukin 1β (IL-1β) can up regulate the level of t-PA and plasminogen activator inhibitor-2 (PAI-2) synthesis by human gingival fibroblasts. Method: In the present study, the levels of t-PA and PAI-2 in gingival crevicular fluid (GCF) were measured from healthy, gingivitis and periodontitis sites and compared before and after periodontal treatment. Crevicular fluid from106 periodontal sites in 33 patients were collected. 24 sites from 11 periodontitis patients received periodontal treatment after the first sample collection and post-treatment samples were collected 14 days after treatment. All samples were analyzed by enzyme-linked immunosorbent assay (ELISA) for t-PA and PAI-2. Results: The results showed that significantly high levels of t-PA and PAI-2 in GCF were found in the gingivitis and periodontitis sites. Periodontal treatment led to significant decreases of PAI-2, but not t-PA, after 14 days. A significant positive linear correlation was found between t-PA and PAI-2 in GCF (r=0.80, p<0.01). In the healthy group, different sites from within the same subject showed little variation of t-PA and PAI-2 in GCF. However, the gingivitis and periodontitis sites showed large variation. These results suggest a good correlation between t-PA and PAI-2 with the severity of periodontal conditions. Conclusion: This study indicates that t-PA and PAI-2 may play a significant rôle in the periodontal tissue destruction and tissue remodeling and that t-PA and PAI-2 in GCF may be used as clinical markers to evaluate the periodontal diseases and assess treatment.

Chlamydial infections represent a major threat to the long-term survival of the koala and a successful vaccine would provide a valuable management tool. Vaccination however has the potential to enhance inflammatory disease in animals exposed to a natural infection prior to vaccination, a finding in early human and primate trials of whole cell vaccines to prevent trachoma. In the present study, we vaccinated both healthy koalas as well as clinically diseased koalas with a multi-subunit vaccine consisting of Chlamydia pecorum MOMP and NrdB mixed with immune stimulating complex as adjuvant. Following vaccination, there was no increase in inflammatory pathological changes in animals previously infected with Chlamydia. Strong antibody (including neutralizing antibodies) and lymphocyte proliferation responses were recorded in all vaccinated koalas, both healthy and clinically diseased. Vaccine induced antibodies specific for both vaccine antigens were observed not only in plasma but also in ocular secretions. Our data shows that an experimental chlamydial vaccine is safe to use in previously infected koalas, in that it does not worsen infection-associated lesions. Furthermore, the prototype vaccine is effective, as demonstrated by strong levels of neutralizing antibody and lymphocyte proliferation responses in both healthy and clinically diseased koalas. Collectively, this work illustrates the feasibility of developing a safe and effective Chlamydia vaccine as a tool for management of disease in wild koalas.

Context: Postprandial dysmetabolism is emerging as an important cardiovascular risk factor. Augmentation index (AIx) is a measure of systemic arterial stiffness and independently predicts cardiovascular outcome. Objective: The objective of this study was to assess the effect of a standardized high-fat meal on metabolic parameters and AIx in 1) lean, 2) obese nondiabetic, and 3) subjects with type 2 diabetes mellitus (T2DM). Design and Setting: Male subjects (lean, n = 8; obese, n = 10; and T2DM, n = 10) were studied for 6 h after a high-fat meal and water control. Glucose, insulin, triglycerides, and AIx (radial applanation tonometry) were measured serially to determine the incremental area under the curve (iAUC). Results: AIx decreased in all three groups after a high-fat meal. A greater overall postprandial reduction in AIx was seen in lean and T2DM compared with obese subjects (iAUC, 2251 +/- 1204, 2764 +/- 1102, and 1187 +/- 429% . min, respectively; P < 0.05). The time to return to baseline AIx was significantly delayed in subjects with T2DM (297 +/- 68 min) compared with lean subjects (161 +/- 88 min; P < 0.05). There was a significant correlation between iAUC AIx and iAUC triglycerides (r = 0.50; P < 0.05). Conclusions: Obesity is associated with an attenuated overall postprandial decrease in AIx. Subjects with T2DM have a preserved, but significantly prolonged, reduction in AIx after a high-fat meal. The correlation between AIx and triglycerides suggests that postprandial dysmetabolism may impact on vascular dynamics. The markedly different response observed in the obese subjects compared with those with T2DM was unexpected and warrants additional evaluation.

The 'open window' theory is characterised by short term suppression of the immune system following an acute bout of endurance exercise. This window of opportunity may allow for an increase in susceptibility to upper respiratory illness (URI). Many studies have indicated a decrease in immune function in response to exercise. However, many studies do not indicate changes in immune function past 2 hours after the completion of exercise, consequently failing to determine whether these immune cells numbers, or importantly their function, return to resting levels before the start of another bout of exercise. Ten male 'A' grade cyclists (age 24.2 +/- 5.3 years; body mass 73.8 +/- 6.5 kg; VO(2peak) 65.9 +/- 7.1 mL.kg(-1).min(-1)) exercised for two hours at 90% of their second ventilatory threshold. Blood samples were collected pre-, immediately post-, 2 hours, 4 hours, 6 hours, 8 hours, and 24 hours post-exercise. Immune variables examined included total leukocyte counts, neutrophil function (oxidative burst and phagocytic function), lymphocyte subset counts (CD4(+), CD8(+), and CD16(+)/56(+)), natural killer cell activity (NKCA), and NK phenotypes (CD56(dim)CD16(+), and CD56(bright)CD16(-)). There was a significant increase in total lymphocyte numbers from pre-, to immediately post-exercise (p<0.01), followed by a significant decrease at 2 hours post-exercise (p<0.001). CD4(+) T-cell counts significantly increased from pre-exercise, to 4 hours post- (p<0.05), and 6 hours post-exercise (p<0.01). However, NK (CD16(+)/56(+)) cell numbers decreased significantly from pre-exercise to 4 h post-exercise (p<0.05), to 6 h post-exercise (p<0.05), and to 8 h post-exercise (p<0.01). In contrast, CD56(bright)CD16- NK cell counts significantly increased from pre-exercise to immediately post-exercise (p<0.01). Neutrophil oxidative burst activity did not significantly change in response to exercise, while neutrophil cell counts significantly increased from pre-exercise, to immediately post-exercise (p<0.05), and 2 hours post-exercise (p<0.01), and remained significantly above pre-exercise levels to 8 hours post-exercise (p<0.01). Neutrophil phagocytic function significantly decreased from 2 hours post-exercise, to 6 hours post- (p<0.05), and 24 hours post-exercise (p<0.05). Finally, eosinophil cell counts significantly increased from 2 hours post to 6 hours post- (p<0.05), and 8 hours post-exercise (p<0.05). This is the first study to show changes in immunological variables up to 8 hours post-exercise, including significant NK cell suppression, NK cell phenotype changes, a significant increase in total lymphocyte counts, and a significant increase in eosinophil cell counts all at 8 hours post-exercise. Suppression of total lymphocyte counts, NK cell counts and neutrophil phagocytic function following exercise may be important in the increased rate of URI in response to regular intense endurance training.

Despite documented changes to mainstream educational systems, Indigenous educational achievements are still at critically low levels across all phases of formal education. According to the Australian Bureau of Statistics (2011) Indigenous students are still less likely than non-Indigenous students to complete their final years of schooling (45% compared with 77% in 2009); tertiary level entry and outcomes are also significantly lower than non-Indigenous entry and outcomes. Although significant research has focused on the area of Indigenous education, in particular, identifying and making recommendations on how to close educational gaps between Indigenous and non-Indigenous people, these studies have failed to bring about the change needed and to engage successfully with Indigenous communities and draw on Indigenous communities’ insights for best practice. This thesis focuses on Indigenous perspectives and takes a closer look at the cultural factors that impact on tertiary education access for Indigenous young men who come from a Bundjalung community on the far north coast of northern New South Wales. To date, this community has not been the focus of serious postgraduate study. Their experiences and the values and ideas of their community have not been investigated. To do this, the study uses an Indigenous methodological framework. It draws on Indigenous Standpoint Theory to analyse data through concepts of the cultural interface and tensions (Nakata, 2007, pp. 195-217). The study’s framing also draws on decolonising methods (Porsanger, 2004; Smith, 1999) and Indigenist research methods (Rigney, 1997). Such methodologies are intended to benefit both the research participants (community members) and the researcher. In doing so, the study draws on Creswell’s (2008) methods of restorying and retelling to analyse the participants’ interviews and yarns about their lives and experiences relating to tertiary educational access. The research process occurred in multiple stages: (1) selection of research sites, (2) granting of access which was requested through consultation with local Aboriginal Elders and through the local Aboriginal Lands Council, (3) conducting of interviews with participants/ data collection, (4) analysis of data, (5) documentation of findings, (6) theory development, and (7) reporting back to the nominated Indigenous community on the progress and findings of the research. The benefits of this research are numerous. First, this study addresses an issue that has been identified from within the local Aboriginal community as an issue of high precedence, looking at the cultural factors surrounding the underrepresentation of Indigenous people accessing tertiary education. This is not only of local significance but has been identified in the literature as a local, national and international area of concern amongst Indigenous peoples (Department of Economic and Social Affairs, 2009; Herbert, 2010; King, 2011). Secondly, the study draws on local Indigenous knowledges and learning processes from within a Bundjalung community to gain inside perspectives, namely the cultural factors that are being expressed from a range of Indigenous community members – young men, community Elders and community members – and finding out what they perceive inhibit and/or promote tertiary education participation within their community. Such perspectives are rarely heard. Finally, recommendations made from this study are aimed at revealing investigative styles that may be utilised by Western institutions to improve access for Indigenous young men living in the Narlumdarlum1 region in the tertiary context.

Immunotherapy is a promising new treatment for patients with advanced prostate and ovarian cancer, but its application is limited by the lack of suitable target antigens that are recognized by CD8+ cytotoxic T lymphocytes (CTL). Human kallikrein 4 (KLK4) is a member of the kallikrein family of serine proteases that is significantly overexpressed in malignant versus healthy prostate and ovarian tissue, making it an attractive target for immunotherapy. We identified a naturally processed, HLA-A*0201-restricted peptide epitope within the signal sequence region of KLK4 that induced CTL responses in vitro in most healthy donors and prostate cancer patients tested. These CTL lysed HLA-A*0201+ KLK4 + cell lines and KLK4 mRNA-transfected monocyte-derived dendritic cells. CTL specific for the HLA-A*0201-restricted KLK4 peptide were more readily expanded to a higher frequency in vitro compared to the known HLA-A*0201-restricted epitopes from prostate cancer antigens; prostate-specific antigen (PSA), prostate-specific membrane antigen (PSMA) and prostatic acid phosphatase (PAP). These data demonstrate that KLK4 is an immunogenic molecule capable of inducing CTL responses and identify it as an attractive target for prostate and ovarian cancer immunotherapy.

The purpose of this study was to investigate if obese children have reduced knee extensor (KE) strength and to explore the relationship between adiposity and KE strength. An observational case-control study was conducted in three Australian states, recruiting obese [n=107 (51 female, 56 male)] and healthy-weight [n=132 (56 female, 76 male)] 10–13 year old children. Body mass index, body composition (dual energy X-ray absorptiometry), isokinetic/isometric peak KE torques (dynamometry) and physical activity (accelerometry) were assessed. Results revealed that compared with their healthy-weight peers, obese children had higher absolute KE torques (P≤0.005), equivocal KE torques when allometrically normalized for fat-free mass (FFM) (P≥0.448) but lower relative KE torques when allometrically normalized for body mass (P≤0.008). Adjustments for maternal education, income and accelerometry had little impact on group differences, except for isometric KE torques relative to body mass which were no longer significantly lower in obese children (P≥0.013, not significant after controlling for multiple comparisons). Percent body fat was inversely related to KE torques relative to body mass (r= -0.22 to -0.35, P≤0.002), irrespective of maternal education, income or accelerometry. In conclusion, while obese children have higher absolute KE strength and FFM, they have less functional KE strength (relative to mass) available for weight-bearing activities than healthy-weight children. The finding that FFM-normalized KE torques did not differ suggests that the intrinsic contractile properties of the KE muscles are unaffected by obesity. Future research is needed to see if deficits in KE strength relative to mass translate into functional limitations in weight-bearing activities.

Men aged 50 years or older are at high risk of melanoma, and both incidence and mortality are increasing in this group1. Skin self-examination (SSE) could be one avenue to improve outcomes from melanoma. Several recent intervention trials successfully increased SSE, but resistance to such interventions is less well studied. This posthoc secondary analysis of interventional study data aimed to identify characteristics of older men who did not take up SSE for the early signs of skin cancer, despite exposure to educational materials during a randomized intervention trial

Over the last ten years, approximately one third of refugee and humanitarian entrants to Australia have been adult men. To date, little research has been done on their health and settlement issues. Many of these men have come from the African continent. This paper reports on the educational and employment outcomes of a group of 173 recently arrived adult African men from refugee backgrounds who have settled in Southeast Queensland. Given the current government policy focus on regional resettlement, the paper compares key outcomes between the adult African men who settled in metropolitan Brisbane with those living in the Toowoomba-Gatton region. The study uses a peer interviewer model and a mixed method approach. Overall, we have found that African men who have settled in regional areas face significantly greater educational and occupational challenges than those who settled in the urban area. They report more negative experiences at educational institutions, are more likely to take jobs that are below their level of skills and qualifications, are more dissatisfied with their jobs, and report greater discrimination and difficulties while trying to secure adequate employment in Australia. A number of policy implications are discussed.
