Acute psychophysiological relationships between mood, inflammatory and cortisol changes in response to simulated physical firefighting work and sleep restriction

This study examined how changes in wildland firefighters' mood relate to cytokine and cortisol levels in response to simulated physical firefighting work and sleep restriction. Firefighters completed 3 days of simulated wildfire suppression work separated by an 8-h (control condition; n = 18) or 4-h sleep opportunity (sleep restriction condition; n = 17) each night. Firefighters' mood was assessed daily using the Mood Scale II and Samn-Perelli fatigue scale. Participants also provided samples for the determination of salivary cortisol and pro- (IL-6, IL-8, IL-1β, TNF-α) and anti-inflammatory (IL-4, IL-10) cytokine levels. An increase in the positive mood dimension Happiness was related to a rise in IL-8 and TNF-α in the sleep restriction condition. A rise in the positive mood dimension Activation among sleep restricted firefighters was also related to higher IL-6 levels. An increase in the negative mood dimension Fatigue in the sleep restriction condition was associated with increased IL-6, TNF-α, IL-10 and cortisol levels. In addition, an increase in Fear among sleep restricted firefighters was associated with a rise in TNF-α. Elevated positive mood and immune activation may reflect an appropriate response by the firefighters to these stressors. To further understand this relationship, subsequent firefighting-based research is needed that investigates whether immune changes are a function of affective arousal linked to the expression of positive moods. Positive associations between negative mood and inflammatory and cortisol levels to physical work and restricted sleep provide useful information to fire agencies about subjective fire-ground indicators of physiological changes.

Relationships between inflammatory cytokine and cortisol responses in firefighters exposed to simulated wildfire suppression work and sleep restriction

The interplay between inflammatory and cortisol responses modulates an appropriate response to a stressor. Exposure to severe stressors, however, may alter the actions and relationships of these responses and contribute to negative health outcomes. Physical work and sleep restriction are two stressors faced by wildland firefighters, yet their influence on the relationship between inflammatory and cortisol responses is unknown. The aim of the present study was to quantify the relationship between the cytokine and cortisol responses to sleep restriction while performing simulated physical wildfire suppression work. Firefighters completed 3 days of simulated physical firefighting work separated by either an 8-h (Control condition; n = 18) or 4-h sleep (Sleep restriction condition; n = 17) opportunity on each of the two nights. Salivary cortisol and inflammatory cytokines (IL-6, IL-8, IL-1β, TNF-α, IL-4, and IL-10) were measured throughout each day. An increase in morning IL-6 was related to a rise (6.2%, P = 0.043) in evening cortisol among firefighters in the sleep restriction condition. Higher morning IL-6 levels were related to increased (5.3%, P = 0.048) daily cortisol levels, but this relationship was not different between conditions. Less pronounced relationships were demonstrated between TNF-α, IL-10, IL-4, and cortisol independent of the sleep opportunity, but relationships did not persist after adjusting for demographic factors and other cytokines. These findings quantify the relationship between cytokine and cortisol responses among wildland firefighters exposed to simulated occupational stressors. Potential disturbances to the IL-6 and cortisol relationship among sleep-restricted firefighters' supports further investigations into the negative health effects related to possible imbalances between these systems.

Parent and family factors associated with service use by young people with mental health problems: a systematic review

AIM: To conduct a systematic review of parent and family factors associated with service use for young people with mental health problems, to inform early intervention efforts aimed at increasing service use by young people. METHODS: A systematic search of academic databases was performed. Articles were included in the review if they had: a sample of young people aged between 5 and 18 years; service use as the outcome measure; one or more parental or family variables as a predictor; and a comparison group of non-service using young people with mental health problems. In order to focus on factors additional to need, the mental health symptoms of the young person also had to be controlled for. Stouffer's method of combining P-values was used to draw conclusions as to whether or not associations between variables were reliable. RESULTS: Twenty-eight articles were identified investigating 15 parental or family factors, 7 of which were found to be associated with service use for a young person with mental health needs: parental burden, parent problem perception, parent perception of need, parent psychopathology, single-parent household, change in family structure and being from the dominant ethnic group for the United States specifically. Factors not found to be related to service use were: family history of service use, parent-child relationship quality, family functioning, number of children, parent education level, parent employment status, household income and non-urban location of residence. CONCLUSIONS: A number of family-related factors were identified that can inform effective interventions aimed at early intervention for mental health problems. Areas requiring further research were also identified.

Researching early career teachers and gender differences: ramifications for rural education

Recent research into the lives of early career teachers’ in Victoria and Queensland suggest that gender remains a significant factor in shaping the careers of those teaching in rural and regional schools. The cohort of nearly 5,000 teachers involved in the ARC-funded research project, ‘Studying the Effectiveness of Teacher Education’ (SETE) has a high proportion of females (78%). This composition is consistent with other large-scale datasets and across four rounds of SETE surveys between 2010-2014, and reflected in Case Studies of a selection of Victorian rural and regional schools. Continued perceptions of teaching as an ‘appropriate’ career for women remains - that is, it is reasonably well paid, with holidays and hours that allow a combination of responsibilities in work and family contexts (Acker, 1994). Yet, the analysis of SETE career progression data shows that employment and career chances of female and male graduate teachers diverge. Male graduates were more likely to be employed in full time positions and saw themselves in a leadership role in three years’ time, while female graduates were more likely to be employed in part-time positions and saw themselves teaching or in other education related occupations in the future. Interestingly, there was also significant difference in the perceptions of preparedness and effectiveness scores for males and females, with female teachers consistently reporting higher scores for both scales. In this paper, we examine the research data with regards to gender differences in rural and regional primary schools and ask the question: thirty years after the first Affirmative Action Plan for Women in the Victorian Teaching Service (1986), why do these gender differences in teaching careers still hold true—and does it matter in rural education?

How calls from carers, friends and family members of someone affected by cancer differ from those made by people diagnosed with cancer; analysis of 4 years of South Australian Cancer Council Helpline data

PURPOSE: The purpose of this study is to determine how people diagnosed with cancer who call the Cancer Council Helpline in South Australia differ from carers/family/friends (caregivers) who call. METHOD: Descriptive, retrospective audit of calls from people who contacted Cancer Council Helpline in South Australia between 16 April 2009 and 16 April 2013 who were diagnosed with cancer (n = 5766) or were the caregivers (n = 5174) of a person with cancer. RESULTS: Caregivers were more likely to be female (p < 0.001); younger in age (p < 0.001); call regarding cancer that was metastasised/widespread/advanced, terminal or at an unknown stage (p < 0.001) and phone requesting general cancer information or emotional support (p < 0.001). This group was more distressed (p < 0.001) but less likely (p = 0.02) to be offered and/or accept referrals to counselling than people diagnosed with cancer who called. Follow-up care was required by 63.5 % of caregivers and 73.1 % of people with cancer according to distress management guidelines; 8.5 and 15.3 %, respectively, accepted referrals to internal services. The most frequently discussed topic for both groups was emotional/psychological concerns. There were no differences in remoteness of residence or call length between groups. CONCLUSIONS: Caregivers represented different demographic groups than people diagnosed with cancer who called this helpline. The two groups phoned for different issues, at different stages of disease progression, displayed different levels of distress and, therefore, may benefit from services being tailored to meet their unique needs. These results also demonstrate the capacity of helplines to complement other health services and confirm that callers to cancer helplines exhibit high levels of distress.

People with dementia and the hospital environment: the view of patients and family carers

Background

A metropolitan geriatric evaluation and management (GEM) facility in Australia was undergoing expansion, and consideration for the needs of individuals with dementia and their family carers was identified as important in planning the new facility. Existing literature revealed that people in hospital value privacy, minimal noise, family amenities and homeliness, but these findings did not consider the perspectives of the person with dementia specifically.

Aim

The aim was to elicit the perspectives of current inpatients with dementia, and their family carers, about the environment/design features that they believe are necessary for people with dementia, and their family carers.

Method and design

This qualitative study utilised in-depth semi-structured interviews to obtain information from current inpatients with dementia and their family carers.

Results

Participants described how the care received was more important than the physical environment; however, participants also valued homeliness, privacy for the patient and for conversations, a shared space without a television and a connection to the outside. Participants described how accommodating carers, providing quiet spaces and appropriate amenities were also important.

Conclusions

While participants valued care over the physical surroundings, they also offered valuable information about their experience in the ward environment. Despite cognitive difficulties, people with dementia were able to provide useful information about the environment within which they were being cared.

Implications for practice

Consumer opinions about hospital design/environment should be considered as an important source of data. Privacy and personal space for people with dementia and their family carers, a connection with the outside environment , and the needs of carers and visitors are all important considerations when designing healthcare environments.

Dividends, leverage, and family ownership in the emerging Indonesian market

We examine the roles of dividends and leverage to mitigate agency problems within familyfirms in Indonesia. Using simultaneous equations, we find a significant negative associationbetween family ownership and dividend payout and a two-way negative relation betweendividend payout and leverage. Our analysis reveals that, compared to non-family firms,family firms tend to maintain a lower dividend pay-out and higher leverage. The presenceof large non-family ownership appears to have an impact on determining levels of privatebenefit control. During the Asian and global financial crisis, family firms changed theirdividend pay-out more than non-family firms did.

Association between autism symptoms and family functioning in children with attention-deficit/hyperactivity disorder: a community-based study

Autism spectrum disorder (ASD) symptoms are elevated in populations of children with attention-deficit/hyperactivity disorder (ADHD). This study examined cross-sectional associations between ASD symptoms and family functioning in children with and without ADHD. Participants were recruited to a longitudinal cohort study, aged 6-10 years (164 ADHD; 198 controls). ADHD cases were ascertained using community-based screening and diagnostic confirmation from a diagnostic interview. ASD symptoms were measured using the Social Communication Questionnaire. Outcome variables were parent mental health, family quality of life (FQoL), couple conflict and support, and parenting behaviours. After adjustment for a range of child and family factors (including other mental health comorbidities), higher ASD symptoms were associated with poorer FQoL across all three domains; emotional impact (p = 0.008), family impact (p = 0.001) and time impact (p = 0.003). In adjusted analyses by subgroup, parents of children with ADHD+ASD had poorer parent self-efficacy (p = 0.01), poorer FQoL (p ≤ 0.05), with weak evidence of an association for less couple support (p = 0.06), compared to parents of children with ADHD only. Inspection of covariates in the adjusted analyses indicated that the association between ASD symptoms and most family functioning measures was accounted forby child internalising and externalising disorders, ADHD severity, and socioeconomic status; however, ASD symptoms appear to be independently associated with poorer FQoL in children with ADHD. The presence of ASD symptoms in children with ADHD may signal the need for enhanced family support.

Supported silver nanoparticle and near-interface solution dynamics in a deep eutectic solvent

Type III deep eutectic solvents (DES) have attracted significant interest as both environmentally friendly and functional solvents that are, in some ways, advantageous to traditional aqueous systems. While these solvents continue to produce remarkable thin films and nanoparticle assemblies, their interactions with metallic surfaces are complex and difficult to manipulate. In this study, the near-surface region (2-600 nm) of a carbon surface is investigated immediately following silver nanoparticle nucleation and growth. This is accomplished, in situ, using a novel grazing transmission small-angle X-ray scattering approach with simultaneous voltammetry and electrochemical impedance spectroscopy. With this physical and electrochemical approach, the time evolution of three distinct surface interaction phenomena is observed: aggregation and coalescence of Ag nanoparticles, multilayer perturbations induced by nonaggregated Ag nanoparticles, and a stepwise transport of dissolved Ag species from the carbon surface. The multilayer perturbations contain charge-separated regions of positively charged choline-ethylene and negatively charged Ag and Cl species. Both aggregation-coalescence and the stepwise decrease in Ag precursor near the surface are observed to be very slow (∼2 h) processes, as both ion and particle transport are significantly impeded in a DES as compared to aqueous electrolytes. Altogether, this study shows how the unique chemistry of the DES changes near the surface and in the presence of nanoparticles that adsorb the constituent species.

Women academics and work–life balance: gendered discourses of work and care

This article examines how discourses of work–life balance are appropriated and used by women academics. Using data collected from semi-structured, single person interviews with 31 scholars at an Australian university, it identifies and explores four ways in which participants construct their relationship to work–life balance as: (1) a personal management task; (2) an impossible ideal; (3) detrimental to their careers; and (4) unmentionable at work. Findings reveal that female academics’ ways of speaking about work–life balance respond to gendered attitudes about paid work and unpaid care that predominate in Australian socio-cultural life. By taking a discursive approach to analysing work–life balance, our research makes a unique contribution to the literature by drawing attention to the power of work–life balance discourses in shaping how women configure their attempts to create a work–life balance, and how it functions to position academic women as failing to manage this balance.

Employer matters in 2003

The year 2003 was characterised by employer proactivism, and a preparedness to pursue new legal manoeuvres to prevent or terminate protected industrial action. A number of employers also resorted to lengthy lockouts (with few positive results) as bargaining tactics in enterprise negotiations. It was the year employers in the manufacturing and metals sector saw off the unions’ ‘Campaign 2003’, giving little ground on the key issues of reduced hours and contributions to trust funds for worker entitlements. The year was a joyous one for employers in the building and construction industry, as their dreams of a shackled and weakened union movement came a step closer to being realised, with the introduction of draconian industry-specific legislation by the Howard Government, arising from the recommendations of the Cole Royal Commission. On a positive note, the year also witnessed all the members of the ‘industrial relations club’ embrace and declare a common concern for work and family balance issues.

Employer matters in 2004

n 2004, employers were active in arguing their cases in a number of important hearings of the Australian Industrial Relations Commission. However, despite a united position among employer ranks and the federal government, employers were generally disappointed with the Commission’s safety net review decision. Both the Australian industry Group and the Australian Chamber of Commerce and Industry found some common ground with the Australian Council of Trade Unions, in a consent position on extending carers leave, but overall employers presented a detailed argument opposing any extension of employee rights in the Commission’s work and family test case. Employers in some sectors were able to reach collective agreements with unions with little industrial disruption, whereas others, such as banking, found the going tougher. Overall, employers, like unions, faced a great deal of uncertainty over what were or were not ‘matters pertaining’, as a number of decisions after the Electrolux case clarified or clouded the issue. Understandably, the year ended on a positive note for most employers, with the Howard Government re-elected with a majority in the Senate, enabling it to pass a further round of radical labour market reforms in 2005.

'I mean, you want to be there for them': young Australian professionals negotiating careers in a gendered world

Popular opinion suggests young Australians are no longer interested in families and/or careers. This longitudinal study of Australian university graduates reports early findings about career orientations, associated long working hours and the work/family nexus. Most participants seem to be what Hakim (2000) regards as 'adaptive' in terms of work and family preferences. It appears more that they are pursuing fulfilling careers while negotiating new and traditional expectations of gender and family. Most seek equalitarian partnerships of shared care-giving and meaningful careers for both partners, with children typically part of their life goals.

When the whole 'bloke' thing starts to crumble : men's access to chronic illness (arthritis) self management programs

This thesis explores the issue of men's access to chronic illness self management programs from a social constructionist perspective. A combination of research methodologies was used; a quantitative analysis to confirm gender differences in levels and patterns of service use; a qualitative analysis to gain an increased understanding of the factors affecting men's access; and a trial to test the application of the research findings. The clients and services of Arthritis Victoria were chosen as the setting for this research. The quantitative analyses were conducted on contingency tables and odds ratios and confirmed that men were under-represented as service users. The analyses also identified gender differences in patterns of service use. The qualitative analysis was based on a series of in-depth, semi-structured interviews. It was undertaken from a grounded theory approach to allow for the development of theoretical explanations grounded in the data. It was found that men's decisions to access chronic illness self management programs were strongly influenced by dominant social constructions of masculinity which constrained help-seeking and health management behaviour. However, the restrictive influence of hegemonic masculinity was progressively undermined by the increasing severity of the chronic condition until a crisis point was reached in terms of the severity of the condition or its impact on lifestyle. This resulted in a reformulation or rejection of hegemonic masculinity. The described conceptual framework was consistent for men from diverse social groupings, although it appeared less prominent in both younger and older men, suggesting that dominant social constructions of masculinity have the greatest influence on health decisions during the middle stage of adulthood when work and family obligations are greatest. The thesis findings informed the development of some guiding principles for reviewing the structure and delivery of chronic illness self management services for men. The guiding principles will have direct application in the planning of Arthritis Victoria programs, and implications for other chronic illness self management programs in Australia, and also in Western countries with a similar health and sociocultural setting to Australia.
