Domestic outsourcing and multitasking: How much do they really contribute?

The bulk of responsibility for domestic work and childcare in heterosexual couples falls on women. But the means they find to cope with this load, and how these means relate to the factors underpinning the division of labor are not often studied. Two much-cited ways of reducing overall work time are purchasing domestic assistance (outsourcing) and the multitasking of domestic/caring tasks. Using UK 2000/2001 time-use data (N = 4196 couples), we find domestic outsourcing is related to having dependent children and to partners’ resources, but has little impact on the total domestic/caring workload of either partner. Nor can outsourcing account for the reduction in women’s unpaid labor with increasing economic resources. Wives spend more time multitasking than husbands, but their proportion of multitasked domestic time is similar, and is not affected by resources or dependent children. Domestic multitasking seems to be more related to opportunity (time at home) than to time pressure.     

Finding overlapping components with MML

We use minimum message length (MML) estimation for mixture modelling. MML estimates are derived to choose the number of components in the mixture model to best describe the data and to estimate the parameters of the component densities for Gaussian mixture models. An empirical comparison of criteria prominent in the literature for estimating the number of components in a data set is performed. We have found that MML coding considerations allows the derivation of useful results to guide our implementation of a mixture modelling program. These advantages allow model search to be controlled based on the minimum variance for a component and the amount of data required to distinguish two overlapping components.

Keynes, legacies, and inquiry

As President Nixon once observed, “we are all Keynesians.” And we do indeed live in a macroeconomic world, essentially, as defined and elucidated by Keynes. But Keynes himself is underrepresented in both political science and in mainstream economics. This is a costly intellectual error. Keynes’ prodigious writings, as well as his actions, offer a treasure trove of inspiration, analysis, and insight. This article considers four themes in Keynes’ oeuvre that are especially worthy of revisiting: the importance of economic inequality, the potentially fragile underpinnings of international economic order, the inherent dysfunctions of the international monetary economy, and, perhaps most important, Keynes’ philosophy and its relationship to economic inquiry.

What Works at Work? Toward an Integrative Model Examining Workplace Campaign Strategies

Many US employees are regularly asked to give charitable donations through work. The techniques used to solicit workplace donations vary. Drawing on a nationally representative survey, the study used a sample of donor responses to examine the effectiveness of several widely used campaign strategies: donor choice, company matching, public recognition, and solicitation support. The theoretical framework built on workplace research by Barman (2007) and established charitable giving mechanisms (Bekkers and Wiepking 2011a, 2011b). The research question was, “Do workplace campaign strategies lead employees to participate and to make (larger) donations in the workplace?” The positive outcomes of the strategies, aside from donor choice, were limited, suggesting that tried‐and‐true workplace fundraising strategies warrant additional scrutiny. The findings are meaningful to campaign managers seeking to identify approaches that generate workplace giving. For researchers, the results confirm growing attention to the importance of purpose‐based giving in comparison with community‐based giving.     

Adaptation and validation of the Gambling Motives Questionnaire-Financial (GMQ-F) in a sample of French-speaking gamblers

Previous research has identified specific gambling motives and linked them with both healthy and disordered gambling. The Gambling Motives Questionnaire (GMQ) is currently the most widely used measure for these motives. The present study aimed to offer a French validation of the latest version of this scale, the GMQ-Financial (GMQ-F), which measures four distinct motives (enhancement, social, coping, financial). The French GMQ-F was completed by 278 gamblers from the community and 22 treatment-seeking pathological gamblers, along with scales assessing gambling cognitions, impulsivity, disordered gambling symptoms and psychopathological symptoms. Confirmatory factor analysis supported the expected four-factor model. The GMQ-F subscales have good internal reliability. Validity of the GMQ-F is supported by specific correlations with the other constructs measured. Pathological gamblers differed from gamblers from the community on all but one (social) of the GMQ-F subscales. The French GMQ-F presents good psychometric properties and constitutes a reliable instrument for measuring gambling motives in research and clinical practice.
