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

Gender differences in research participation have been documented in both quantitative and qualitative studies, a pattern that is particularly pronounced in studies of reproduction. We use the National Survey of Fertility Barriers to analyze three reasons frequently used to explain men's non‐participation in reproductive research: (1) Reproduction is a sensitive subject for men, (2) reproduction is women's domain, and (3) men's unavailability due to seemingly pragmatic reasons (e.g., work schedule). Using binary logistic regression, we test these three explanations across two different models: women's gatekeeping (denying researcher access to partners) (n = 1,637) and men's own non‐response (n = 1,454). A substantial minority of women (12.8 percent), engaged in gatekeeping, but the dominant mechanism of men's non‐participation was their own non‐response once women granted researcher access to partners. Consistent with prior studies on general survey non‐response, several demographic variables were associated with men's participation. Additionally, findings suggest that the notion of reproduction as women's domain received the strongest support, though specific variables within this construct differed for models predicting women's gatekeeping versus men's non‐response of their own accord.  相似文献

The Panama Canal’s handover from US governance to Panamanian sovereignty concluded on 31 December 1999. ‘Patria Entera’ (loosely translated as ‘Whole Homeland’), a state-sponsored open-air concert, commemorated the handover and promulgated new readings of the Panama Canal Zone’s decolonisation process. Concert headliner Rubén Blades deployed repertory and symbolic strategies to counterbalance Panamanians’ ambivalence regarding the handover. ‘Patria Entera’ recast the Panama Canal Zone as an accessible space and narrated the handover as the Panamanian citizenry’s collective inheritance of the Canal and accompanying Zone. Yet the concert’s discursive arc overlooked persistent and emerging challenges.  相似文献

Freedom of information laws are intended to illuminate how governments operate. However, the operations of governments increasingly involve algorithms, such as those used to recommend criminal sentencing and determine eligibility for social services. Algorithms function as ‘black boxes’ that turn inputs into outputs using processes that are often, by design, not transparent. Freedom of information laws allow one potential means for algorithmic transparency. However, whether such laws can be used to access algorithms is unclear. This research examines, in two ways, the availability of government algorithms to the public. First, this study examines laws, regulations, advisory opinions, and court rulings relevant to the disclosure of algorithms. The second part of this study analyzes actual responses by US government agencies to Freedom of Information Act requests for algorithms. This study concludes that governmental policies and practices related to algorithmic disclosure are inconsistent. Such inconsistencies suggest a need for better mechanisms to hold government algorithms accountable.  相似文献

Tax data suggest that the population of adult dependents—adults relying on the support of others for the majority of their financial needs—has more than doubled over the last decade. However, little is known about how taxes affect the labor supply decisions of this population. This paper provides an initial investigation, studying the impact of the Earned Income Tax Credit (EITC) expansions of the early 1990s on the labor supply of adult dependents living with their relatives. I find that dependent individuals who were not a part of the nuclear family responded to the EITC expansions, increasing labor force participation by about 5 percentage points. For adult children, I show that the absence of a net response is likely due to an unexpected consequence of the EITC: expanded family credits led to a decrease in their labor force participation.  相似文献

Local emergency managers are charged by the U.S. Department of Homeland Security to increase the number of community members with emergency plans and kits. This outcome remains unrealized in part based upon in-depth interviews with 37 emergency managers in eight states revealing that emergency managers conceptualize communication as dissemination rather than as a process of research and evaluation. This study calls for local emergency managers to conduct outcome evaluations of risk communication campaigns to increase public participation.  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.
