Gender scholars have developed a significant body of scholarship on the reproduction of gender inequality in work organizations. However, the vast majority of that research has been conducted in non‐profit organizations or in employer‐owned businesses. In this article, we review the existing literature on gender in worker‐owned businesses. We begin by defining three distinctly different types of worker‐owned businesses: companies with employee stock ownership plans, worker cooperatives, and communes. Next we review the limited research on gender inequality in each of these organizational forms. The current literature finds that women benefit from working in these alternative organizations, but gender disparities nevertheless persist due to occupational segregation and the devaluation of domestic work. Exceptions are those organizations with strong ties to feminism and those with formal power‐sharing policies. Granted the scarcity of research on this topic, however, these conclusions are tentative. We conclude with a discussion of areas for further research.  相似文献

The effects of climate change are both acute and chronic, leaving many communities in a perpetual state of uncertainty. For others, there is no such uncertainty—their communities will soon be uninhabitable. Some levels of government have begun to recognize and slowly respond to communities facing the possibilities of relocation. This paper considers the impact of transdisciplinary thinking and collaborative moments in the planning phase of one of the few community-scale managed retreat attempts in the United States. In January 2016, the US Department of Housing and Urban Development (HUD) awarded the state of Louisiana $48.3 million to plan, design, and implement a structured and scalable resettlement with former and current residents of Isle de Jean Charles. The paper uses data from surveys and interviews with the practitioner team, fieldnotes, review of published reports, and a sample of more than 400 media accounts. Our analysis highlights how developing a transdisciplinary process may render a new understanding to the tasks and meanings of planning resettlements in the future.  相似文献

This study sought to examine the intermediary roles of different topics of conflict and negative emotions following conflicts in the associations between attachment insecurities and relationship satisfaction in a sample of 253 mixed-gender couples from the community. Results from path analyses based on the Actor–Partner Interdependence Model showed that attachment anxiety and attachment avoidance were associated with the perception, in both partners, of experiencing more conflicts in the relationship. In turn, the more participants perceived conflicts related to major issues and daily annoyances, the more they reported negative emotions following conflicts and lower relationship satisfaction. Participants’ report of conflicts related to major issues was also related to their partner's lower relationship satisfaction. Findings highlight the significance of accounting for the topics on which couples argue and of using an attachment-based framework to help couples deal with the negative emotions that they experience following conflicts.  相似文献

A recent Institute of Medicine report on “The Assessment or Readjustment Needs of Veterans, Service Members, and Their Families” http://nationalacademies.org/hmd/Reports/2013/Returning-Home-from-Iraq-and-Afghanistan.aspx, (2013) underscored the need for effective support for military families with young children, and that effective engagement into existing services remains a challenge. This mixed-method study involved 14 fathers (previously deployed military) who engaged in the Strong Military Families Program, a resiliency-building group for families with young children. The purpose of this paper was twofold: first, to identify the efficacy of this brief intervention for reducing mental health symptomatology among previously deployed military fathers who completed the group, and second to better understand the perceptions and reflections of fathers who completed an effective symptom management program in order to fill the literature gap around this issue and guide future efforts at increasing engagement of this population. Pre- and post-group assessments were administered including depression and posttraumatic stress symptom ratings. Assessments also included interviews designed to elicit fathers’ expectations before the program and to capture their reflections after completion. Quantitative analyses examined changes in symptoms pre- to post-group, and qualitative analyses aimed to better understand fathers’ experiences and help guide future efforts to increase engagement of this population. A grounded theory approach was employed to analyze interview content, and two themes were identified reflecting a desire for (1) connection and (2) learning. The prominence of these themes both before and after group underscored the value of connection to others who shared experience and opportunity for learning effective parenting strategies. Corresponding quantitative analyses indicated a significant decrease in self-reported posttraumatic stress (p?<?.05) and trend level reduction in depression (p?<?.10), suggesting participation may contribute to more effective symptom management. Subgroup analyses contrasting the pre-group interviews of fathers who endorsed higher (n?=?9) versus lower (n?=?5) levels of symptoms revealed that those with greater symptomatology expressed more themes related to fear of committing to the program. Discussion will focus on effective outreach and engagement, and the need to align programs to the interests of previously deployed fathers of young children.  相似文献

We address the issue of performing testing inference in the class of zero-inflated power series models. These models provide a straightforward way of modelling count data and have been widely used in practical situations. The likelihood ratio, Wald and score statistics provide the basis for testing the parameter of inflation of zeros in this class of models. In this paper, in addition to the well-known test statistics, we also consider the recently proposed gradient statistic. We conduct Monte Carlo simulation experiments to evaluate the finite-sample performance of these tests for testing the parameter of inflation of zeros. The numerical results show that the new gradient test we propose is more reliable in finite samples than the usual likelihood ratio, Wald and score tests. An empirical application to real data is considered for illustrative purposes.  相似文献

The FDA released the final guidance on noninferiority trials in November 2016. In noninferiority trials, validity of the assessment of the efficacy of the test treatment depends on the control treatment's efficacy. Therefore, it is critically important that there be a reliable estimate of the control treatment effect—which is generally obtained from historical trials, and often assumed to hold in the current setting (the assay constancy assumption). Validating the constancy assumption requires clinical data, which are typically lacking. The guidance acknowledges that “lack of constancy can occur for many reasons.” We clarify the objectives of noninferiority trials. We conclude that correction for bias, rather than assay constancy, is critical to conducting valid noninferiority trials. We propose that assay constancy not be assumed and discounting or thresholds be used to address concern about loss of historical efficacy. Examples are provided for illustration.  相似文献

Earned income tax credit (EITC) benefit income is paid out in a lump‐sum around tax time. We investigate whether savings and debt among EITC‐eligible families reflect the timing of payments. Using nationally representative, individual‐level data on self‐reported debt and savings outcomes, we search for differences in monthly behavior between EITC‐eligible and ‐ineligible households. We find evidence that credit card and unsecured debt holding among EITC‐eligible families reflects the timing of the EITC, with low debt levels at tax time relative to other months. Debt holding among ineligible families with children does not exhibit a similar pattern. We find limited evidence of intrayear patterns in savings behavior among EITC‐eligible families.

In this article, we detail the politics and practicalities of co‐produced disability research with disabled young people with life‐limiting and life‐threatening impairments. We centre an ESRC‐funded arts‐informed co‐produced research project that has brought together a Co‐Researcher Collective of disabled young people. Co‐production is an established approach; however, our co‐researchers have led us to develop inclusive research practices that engage with online social research methods in innovative ways. As we detail our experiences, we aim to encourage disability studies researchers and others to adopt virtual environments when researching with and for the lives of disabled people.  相似文献

Work organizations are commonly studied as sites that produce and reproduce inequality. But we know much less about how organizations promote equality. This article examines efforts to broaden access to power, opportunity, and resources in Hotel Bauen, a worker-recuperated business that was converted from a privately-owned company into a worker-run cooperative. Drawing on extensive ethnographic and archival research, I analyze efforts to redesign and redefine work through collective decision-making, job rotation, and pay equity. The article concludes by identifying three mechanisms of equality—inclusion, opportunity distribution, and symbolic leveling—to theorize the relational production of workplace equality and complement the near-exclusive focus on inequality and its effects.

Worldwide, cities are investing in greenspace to enhance urban quality of life and conserve biodiversity. Cities should ensure these investments do not unintentionally result in ecosystem disservices. Municipal management decisions regarding urban greenspaces, such as mowing frequency, could influence mosquito communities and public health. We examined how mowing, resultant vegetation characteristics, and landscape context influenced adult mosquito abundance in urban vacant lots. We sampled adult Culex and Aedes mosquitoes in a network of vacant lots within eight Cleveland, Ohio, USA neighborhoods in 2015 and 2016 using CO2-baited light traps and grass-infused gravid traps. For each lot, we quantified vegetation characteristics, including plant diversity, bloom area, and biomass, as well as the surrounding landscape composition at radii of 60 and 1000 m. We found that periodic mowing did not significantly affect mosquito abundances. However, vacant lots with more diverse plant communities were associated with a greater light trap capture of both Culex and Aedes. Both mosquito genera declined in light trap catches with increased impervious surface at 60 m. Similarly, Culex (gravid trap) declined with the amount of built infrastructure at 1000 m. In contrast, Aedes (light trap) increased with the concentration of buildings in the landscape at 1000 m. Our findings indicate that reducing the frequency of mowing within vacant lots will not necessarily increase adult mosquito abundance. Nonetheless, mosquito surveillance and management should be considered when planning conservation-focused greenspaces, as vegetation design choices and the landscape context of a site do influence vector abundance and potentially disease risk.
