Work–Life Balance and Parenthood: A Comparative Review of Definitions,Equity and Enrichment*

This review investigates the problems of definition and inequity with which the literature on parenthood and work–life balance is beset. It analyses research trajectories first within the established disciplines of organizational psychology and the sociologies of work and family practices, and then within the newer field of management studies. Gender, class and difference are singled out as troubling themes, especially in relation to fathers and impoverished parents. A tendency towards mono‐disciplinarity is observed within organizational psychology and sociologies of work and family practices. The review offers explanations for the historic but narrow definition within organizational psychology and sociologies of work and family practices of work–life balance as affecting mainly heterosexual dual‐career parent couples. The authors show how this narrow definition has led to inequities within research. They further identify as limiting the definition of work–life balance to be always ‘problematic’, rather than enriching, among employed parents. Consequently, a three‐factor framework is recommended, through which future studies may address the problems of definition and equity in work–life balance literature, including: a broader definition of work–life balance to include marginalized parents; the defining of parenting and employment as potentially life‐enriching; and a commendation of the transdisciplinary approach within management studies as poised to move debate forward.     

The Day-to-Day Reality of Delivering Shelter Services to Women Exposed to Intimate Partner Violence in the Context of System and Policy Demands

ABSTRACT

Intimate partner violence (IPV) is the most common form of gender-based violence affecting Canadian women. Women often seek help from shelters to deal with IPV and its consequences. These shelters function within a broader context that shapes how services are delivered. This study was undertaken to better understand how structural factors including policies shape shelter service delivery and reveal systemic and structural complexities that influence those services and women's ability to rebuild their lives. This feminist qualitative study combined in-depth interviews and focus groups with 37 staff and 4 executive directors from 4 shelters in Ontario, Canada, and included critical discourse analysis of salient policy texts. The findings illuminate the complexity of the structural challenges faced by abused women and the shelters that support them. Systemic impediments were shown to determine how shelters support abused women, the obstacles women face moving forward, and the extent and availability of their options. Future research should include policy evaluation of policy written and enacted, cost analysis examining the actual costs of delivering shelter services and supporting women after leaving, examination of potential alternatives to the identified structural challenges, and investigation of system coordination of services and support for abused women.     

Tracking national and regional spatial-temporal mortality risk associated with NO2 concentrations in Canada: a Bayesian hierarchical two-level model

The association between daily variations in urban air quality and mortality has been well documented using time series statistical methods. This approach assumes a constant association over time. We develop a space-time dynamic model that relaxes this assumption, thus more directly examining the hypothesis that improvements in air quality translate into improvements in public health. We postulate a Bayesian hierarchical two-level model to estimate annual mortality risks at regional and national levels and to track both risk and heterogeneity of risk within and between regions over time. We illustrate our methods using daily nitrogen dioxide concentrations (NO2) and nonaccidental mortality data collected for 1984-2004 in 24 Canadian cities. Estimates of risk and heterogeneity are compared by cause of mortality (cardio-pulmonary [CP] versus non-CP) and season, respectively. Over the entire period, the NO2 risk for CP mortality was slightly lower but with a narrower credible interval than that for non-CP mortality, mainly due to an unusually low risk for a single year (1998). Warm season NO2 risk was higher than cold season risk for both CP and non-CP mortality. For 21 years overall there were no significant differences detected among the four regional NO2 risks. We found overall that there was no strong evidence for time trends in NO2 risk at national or regional levels. However, an increasing linear time trend in the annual between-region heterogeneities was detected, which suggests the differences in risk among the four regions are getting larger, and further studies are necessary to understand the increasing heterogeneity.     

Reliability of normalisation methods for EMG analysis of neck muscles

Acceptable reliability of normalisation contractions in electromyography (EMG) is paramount for testing conducted over a number of days or if normal laboratory strength testing equipment is unavailable. This study examined the reliability of maximal voluntary isometric contractions (MVIC) and sub-maximal (60%) isometric contractions for use in neck muscle EMG studies. Surface EMG was recorded bilaterally from eight sites around the neck at C4/5 level from five healthy male subjects. Subjects performed MVIC and sub-maximal normalisation contractions using an isokinetic dynamometer (ID) and a portable cable dynamometer with attached strain gauge (PCD) in addition to a MVIC against a manual resistance (MR). Subjects were tested in flexion, extension, left and right lateral bending and were retested by the same tester within a two-week period. Intra class correlation co-efficients (ICC) were calculated for each testing method and contraction direction and a mean ICC was calculated across all contraction directions. All normalisation methods produced excellent within-day reliability (mean ICC >0.80) but only the MVICs using the ID and PCD had acceptable reliability when assessed between-days. This study confirmed the validity of using MVICs elicited using the ID and PCD as reliable reference contractions for the normalisation of neck EMG.     

An acarine predator-prey population infesting roses

Summary WhenPhytoseiulus persimilis was reared withTetranychus urticae, infesting roses propagated in a greenhouse at controlled daily temperatures of 24°C (12 hrs) and 18°C (12 hrs), prey numbers fluctuated with peaks of increasing amplitude. Differential dispersal of prey and predator species was one factor contributing to the inability of the natural enemy to control the pest population.     

Estimating Quality of Life and Place with Location Theory: The McBucks Index

This paper explores the changes in inequality and welfare between EU regions at the NUTS 3 level over the 2003–2011 period. Changes in absolute and relative inequalities are broken down into components explaining the effects of population change, re-ranking of regions and income growth between regional per capita incomes. Each component of inequality change is further decomposed by subgroup, revealing the contributions arising from changes within subgroups and from changes between subgroups. The decomposition of the change in absolute inequality is used to develop a decomposition of the change in welfare between EU regions.
