A Comparison of Estimation Methods on the Coverage Probability of Satterthwaite Confidence Intervals for Assay Precision with Unbalanced Data

Construction of closed-form confidence intervals on linear combinations of variance components were developed generically for balanced data and studied mainly for one-way and two-way random effects analysis of variance models. The Satterthwaite approach is easily generalized to unbalanced data and modified to increase its coverage probability. They are applied on measures of assay precision in combination with (restricted) maximum likelihood and Henderson III Type 1 and 3 estimation. Simulations of interlaboratory studies with unbalanced data and with small sample sizes do not show superiority of any of the possible combinations of estimation methods and Satterthwaite approaches on three measures of assay precision. However, the modified Satterthwaite approach with Henderson III Type 3 estimation is often preferred above the other combinations.     

The godmother of gendered organizations: In celebration of the work of Joan Acker

Joan Acker can be considered the godmother of gendered organizations. In this paper, we reflect on the impact that Joan Acker's work has on our thinking and our careers as gender scholars in management and organization studies in Europe. First, we tell our personal stories of close encounters with Joan Acker. Second, we highlight what we consider to be two key contributions of Joan Acker. The first are the interrelated gendered processes regarding structure, culture, interaction and identity from her work in the early 1990s, the second the notion of inequality regimes from her later work on the intersections of gender, class and race. We then discuss how Acker's work has been influential in our research on gendered organizations, and in our teaching when we use it in our explanations of the functioning of gender in organizations to students, and in our work as advisors and consultants for organizations interested in equality, diversity and inclusion. Finally, we elaborate on new directions building on Acker's work, especially in current theorizing on gender and diversity in organizational change.     

Impact of Public and Private Cash Transfers on Poverty and Inequality: Evidence from Vietnam

This article investigates the extent to which public and private transfers affected poverty and inequality in Vietnam in the mid‐2000s. It finds that the impact of public transfers on poverty was negligible, due to the low coverage of the poor and the relatively small amounts transferred. Moreover, the effect of the receipt of transfers on expenditures was small: recipients decreased the labour supply and only a limited amount of the extra income went to current consumption. Domestic private transfers were somewhat more successful in reducing poverty. With most public and private transfers going to non‐poor households, inequality was only marginally affected.     

Work–Family Conflict Among Employees and the Self-Employed Across Europe

This article examines the level of work–family conflict of self-employed persons, a changing but neglected group in work–life research, compared to employees in Europe. Differences between the two groups are explained by looking at job demands and resources. The inclusion of work–family state support makes it possible to examine differences between countries. Multilevel analysis has been applied to data from the European Social Survey (ESS 2010). The results show that job demands and resources operate differently for employees and the self-employed. The relationship between employment type and WFC is mediated mainly by job demands such as working hours, working at short notice, job insecurity and supervisory work. The results also reveal variation across countries that cannot be explained by state support, signalling the need for a more complete understanding of WFC from a cross-national perspective.     

Ghosts of Policing Strategies Past: Is the New Zealand Police ‘Prevention First’ Strategy Historic,Contemporary or the Future?

Since the 1990s the New Zealand Police have introduced three extensive change management programs to improve the efficiency and effectiveness of their core services; Policing 2000, Policing Excellence and Prevention First. Each program has been fundamentally different, with the more modern programs influencing the way that New Zealand Police deliver services. Policing 2000 evolved from implementation of the first strategic plan, while Policing Excellence and Prevention First were introduced in response to the 2007 fiscal crisis. The programs are compared to identify the differences, and whether these later programs can increase service delivery efficiency and effectiveness.     

Vertical wage differences in hierarchically structured firms

In this paper, we present a cooperative model of a hierarchically structured firm to study wage differences between different levels in such a firm. We consider a class of wage functions that are based on marginal contributions to production. It turns out that the wage of a manager is always at least as high as the wage of its subordinates. On the other hand, the wage of a manager never exceeds the sum of the wages of its direct subordinates. These bounds are sharp in the sense that we can characterize for which production processes they are reached. For the class of constant elasticity of substitution (CES) production functions this implies that the wage differences are maximal for linear production functions, and they are minimal for Cobb–Douglas production functions.     

Remittances in Ghana: Origin, Destination and Issues of Measurement

Few studies on remittances have focused on sub-Saharan Africa. This paper analyses a nationwide survey of 5,998 households to determine the characteristics of both internal and overseas remittances in Ghana. Particular attention is paid to the poverty-alleviation potential of remittances. Furthermore, this study uses a smaller scale pilot project with a matched sample of senders and receivers of remittances to identify some problems with using household-level surveys to assess the volume and impact of overseas remittances, and offers some suggestions as to how to handle these problems. The paper estimates that foreign remittances may be three times as large as Bank of Ghana estimates, bringing Ghana on par with large remittance receiving countries such as the Philippines and Mexico. The paper concludes that while foreign remittances are larger in value, locally sent remittances reach poorer segments of the population. Both foreign and local remittances are unevenly geographically distributed, being received more in the centre and southern regions than in northern Ghana where the poorest regions are. The paper argues a need to study multiplier effects of foreign remittances, as these can be large and eventually accrue to rural populations.     

‘Not worth mentioning’: The implicit and explicit nature of decision-making about the division of paid and domestic work

The aim of this qualitative study of 31 Dutch couples is to help us understand why the division of paid and unpaid work between women and men remains stubbornly unequal, despite women's gains in the workplace and rising educational levels. This study expands on other research by documenting daily implicit and explicit decision-making about the division of paid and domestic work by couples during a unique period of their lives: the formative years of their relationship, until they are expecting their first child. Our findings indicate that in general, these Dutch couples do not look explicitly at their division of paid and domestic work, and that this often perpetuates a gendered division of work. More explicit decision-making occurs when couples have a very strong preference for equal sharing, or when the partners disagree or feel frustrated with their current situation. One important finding of this study is that even the couples who prefer to divide the work equally often end up following traditional patterns. This has to do with the decision-making strategies they apply, which seem to be grounded in ambivalent feelings about roles and responsibilities and often romanticizing relationships. Such ambivalence functions as a barrier to more effective decision-making processes. Data from this study seems to suggest that couples wanting to share household responsibilities should, as a minimum, engage in explicit decision-making until they have developed egalitarian routines.     

ERP implementation: An integrated process of radical change and continuous learning

This paper seeks to develop management theory that can be used to increase the likelihood of ERP implementation success. The paper argues and demonstrates that an ERP implementation can be understood as an intended radical change that can be managed to some extent. But during the use of the system, incremental changes are bound to take place, which are unintended and difficult to manage. Using, therefore, and combining positivist and constructivist viewpoints, six different propositions on ERP implementation are developed. The paper reasons that organizations that understand these propositions are more likely to implement and use ERP successfully. The findings of a longitudinal case study of the implementation and use of BaaN in a Danish company support the propositions put forward in the paper.
