The influence of ozone precursor emissions from four world regions on tropospheric composition and radiative climate forcing

Ozone (O3) precursor emissions influence regional and global climate and air quality through changes in tropospheric O3 and oxidants, which also influence methane (CH4) and sulfate aerosols (SO42−). We examine changes in the tropospheric composition of O3, CH4, SO42− and global net radiative forcing (RF) for 20% reductions in global CH4 burden and in anthropogenic O3 precursor emissions (NOx, NMVOC, and CO) from four regions (East Asia, Europe and Northern Africa, North America, and South Asia) using the Task Force on Hemispheric Transport of Air Pollution Source-Receptor global chemical transport model (CTM) simulations, assessing uncertainty (mean ± 1 standard deviation) across multiple CTMs. We evaluate steady state O3 responses, including long-term feedbacks via CH4. With a radiative transfer model that includes greenhouse gases and the aerosol direct effect, we find that regional NOx reductions produce global, annually averaged positive net RFs (0.2 ± 0.6 to 1.7 ± 2 mWm−2/Tg N yr−1), with some variation among models. Negative net RFs result from reductions in global CH4 (−162.6 ± 2 mWm−2 for a change from 1760 to 1408 ppbv CH4) and regional NMVOC (−0.4 ± 0.2 to −0.7 ± 0.2 mWm−2/Tg C yr−1) and CO emissions (−0.13 ± 0.02 to −0.15 ± 0.02 mWm−2/Tg CO yr−1). Including the effect of O3 on CO2 uptake by vegetation likely makes these net RFs more negative by −1.9 to −5.2 mWm−2/Tg N yr−1, −0.2 to −0.7 mWm−2/Tg C yr−1, and −0.02 to −0.05 mWm−2/Tg CO yr−1. Net RF impacts reflect the distribution of concentration changes, where RF is affected locally by changes in SO42−, regionally to hemispherically by O3, and globally by CH4. Global annual average SO42− responses to oxidant changes range from 0.4 ± 2.6 to −1.9 ± 1.3 Gg for NOx reductions, 0.1 ± 1.2 to −0.9 ± 0.8 Gg for NMVOC reductions, and −0.09 ± 0.5 to −0.9 ± 0.8 Gg for CO reductions, suggesting additional research is needed. The 100-year global warming potentials (GWP100) are calculated for the global CH4 reduction (20.9 ± 3.7 without stratospheric O3 or water vapor, 24.2 ± 4.2 including those components), and for the regional NOx, NMVOC, and CO reductions (−18.7 ± 25.9 to −1.9 ± 8.7 for NOx, 4.8 ± 1.7 to 8.3 ± 1.9 for NMVOC, and 1.5 ± 0.4 to 1.7 ± 0.5 for CO). Variation in GWP100 for NOx, NMVOC, and CO suggests that regionally specific GWPs may be necessary and could support the inclusion of O3 precursors in future policies that address air quality and climate change simultaneously. Both global net RF and GWP100 are more sensitive to NOx and NMVOC reductions from South Asia than the other three regions.

Let's talk about sex(ism): cross-national perspectives on women partners’ narratives on equality and sexism at work in Germany and the UK

While the accounting academy has contributed in important ways to furthering our understanding of the relative absence of women in top positions in Professional Service Firms, in-depth empirical research that focuses specifically on sexism is rare, especially so from a cross-national perspective. Drawing on sixty interviews with women partners in public accountancy firms in Germany and the United Kingdom, this article examines how women partners talk about sexism and equal opportunities in the accountancy profession and considers how these narratives are patterned cross-nationally. Employing cultural theory, this study explores how elite women discursively relate to sexism and equal opportunities through their career histories and demonstrates the complex interrelation between the context in which these narratives are produced and the past and present positions of the respondents. Interestingly, it was the German respondents who drew on problematic notions of ‘choice’ and responsibility, where it was upon women to make a choice between their careers and home lives, while this decision-making process was not expected from men. This was in contrast to the accounts of the UK participants who, although also unveiling tensions in their talk, were more inclined to acknowledge continuing structural constraints.

Effects of a holistic health program on women's physical activity and mental and spiritual health

Intervention studies aimed at promoting increased physical activity have been trialled in many different settings including primary care, worksites and the community. Churches are also potential settings for physical activity promotion. However, little is known about the effectiveness of this setting for promoting physical activity, particularly in Australia. The purpose of this study was to evaluate the effectiveness of a mind, body and spiritually based health promotion program in increasing physical activity and promoting mental and spiritual health. Nineteen women completed the 8-week intervention, and 30 women in a non-health related 8-week program at the same church comprised a comparison group. Pre- and post-program surveys assessed outcome measures. Between-group differences over time were examined using one-way MANOVA's. Physical activity was higher in the intervention group than the comparison group. In contrast to the comparison group, both mental health (depression symptoms) and spiritual health improved significantly more among intervention participants. The data highlight the potential for a church-based setting and holistic approach to health promotion as a successful means of increasing physical activity and promoting mental and spiritual health among Australian women.

A status report on women academic accountants in Australia

This paper reports the findings of a survey of the attributes, career satisfactions and aspirations of Australian Academic Women Accountants (AAWA). The survey sought information about personal characteristics, institutional role expectations and perceptions of gender-related issues involving recruitment, promotion and retention of AAWAs. The data provide not only an interesting insight into respondents' perceptions of a career in academic accounting, but also a comparative measure against which future progress of AAWAs can be evaluated. The paper makes suggestions for facilitating the career paths of AAWAs at both institutional and individual levels.

Socioeconomic influences on women's eating behaviours

This thesis investigated the socioeconomic influences on women's eating behaviours. Results showed that women of low socioeconomic position not only perceived higher direct financial costs as a predominant barrier for consuming a healthy diet, but also a number of indirect or non-financial cost factors such as the perceived additional time costs involved in preparing and cooking healthy foods.

Effect of type and severity of intimate partner violence on women's health and service use : findings from a primary care trial of women afraid of their partners

Intimate partner violence (IPV) has major affects on women’s wellbeing. There has been limited investigation of the association between type and severity of IPV and health outcomes. This article describes socio-demographic characteristics, experiences of abuse, health, safety, and use of services in women enrolled in the Women’s Evaluation of Abuse and Violence Care (WEAVE) project. We explored associations between type and severity of abuse and women’s health, quality of life, and help seeking. Women (aged 16–50 years) attending 52 Australian general practices, reporting fear of partners in last 12 months were mailed a survey between June 2008 and May 2010. Response rate was 70.5% (272/386). In the last 12 months, one third (33.0%) experienced Severe Combined Abuse, 26.2% Physical and Emotional Abuse, 26.6% Emotional Abuse and/or Harassment only, 2.7% Physical Abuse only and 12.4% scored negative on the Composite Abuse Scale. A total of 31.6% of participants reported poor or fair health and 67.9% poor social support. In the last year, one third had seen a psychologist (36.6%) or had 5 or more general practitioner visits (34.3%); 14.7% contacted IPV services; and 24.4% had made a safety plan. Compared to other abuse groups, women with Severe Combined Abuse had poor quality of life and mental health, despite using more medications, counseling, and IPV services and were more likely to have days out of role because of emotional issues. In summary, women who were fearful of partners in the last year, have poor mental health and quality of life, attend health care services frequently, and domestic violence services infrequently. Those women experiencing severe combined physical, emotional, and sexual abuse have poorer quality of life and mental health than women experiencing other abuse types. Health practitioners should take a history of type and severity of abuse for women with mental health issues to assist access to appropriate specialist support.
