Conflicting violations of transitivity and where they may lead us

The literature contains evidence from some studies of asymmetric patterns of choice cycles in the direction consistent with regret theory, and evidence from other studies of asymmetries in the opposite direction. This article reports an experiment showing that both patterns occur within the same sample of respondents operating in the same experimental environment. We discuss the implications for modelling behaviour in such environments.     

Inverse J Effect of Economic Growth on Fertility: A Model of Gender Wages and Maternal Time Substitution

This paper presented a model where economic growth, via growth in female wages relative to male wages, encouraged households to raise paid female labor supply and have more children by substituting child care for maternal time. A threshold logarithm per capita output, above which fertility decline reverses, was predicted to depend on subsidized child care, maternity pay, and the value placed on children and maternal time spent rearing children. The predictions explained recent evidence and identified cross country differences in gender wages, family policy and willingness to substitute maternal time in childrearing as important factors in an inverse J-shaped effect of economic growth on fertility. The analysis was robust to the introduction of education and cost sharing among children in child rearing. Economies of scale in child rearing reduced the threshold logarithm of per capita output. Demand for child quality continued to rise with wages despite fertility decline reversal.     

WHEN DO SHELTER‐IN‐PLACE ORDERS FIGHT COVID‐19 BEST? POLICY HETEROGENEITY ACROSS STATES AND ADOPTION TIME

This study explores the impact of Shelter‐in‐Place Orders (SIPOs) on health, with attention to heterogeneity in their impacts. First, using daily state‐level social distancing data, we document that adoption of a SIPO was associated with a 9%–10% increase in the rate at which state residents remained in their homes full‐time. Using daily state‐level coronavirus case data, we find that approximately 3 weeks following the adoption of a SIPO, cumulative COVID‐19 cases fell by approximately 53.5%. However, this average effect masks important heterogeneity across states‐early adopters and high population density states appear to reap larger benefits from their SIPOs. (JEL H75, I12, I18)     

Computerized Immediate Feedback Increases Product Recall Efficiency Due to Interlocking Contingencies in Food Manufacturing

Food manufacturing companies are challenged with tracking their products so that the company will be able to remove that product from circulation quickly and effectively in the event of a product recall. The accuracy of a recall is dependent upon the accuracy of a product selected for order fulfillment, with the correct product going to the correct store. An integrated solution using wireless handheld computers was programmed to provide immediate visual and audio feedback to the order selectors, in order to prevent errors in order selection. For each case selected, vital information was archived to databases in real-time, which in turn, allowed the company’s safety manager to perform quick and accurate product recall tracking in mock recall drills and state inspections. Results were discussed in terms of the expanding the role of the Organizational Behavior Management professional who addresses operational and ethical issues associated with technologies for better consumer safety.     

Grief,loss, and separation: Experiences of birth children of foster carers

Previous research identifies the increased exposure of birth children of foster carers to experiences of separation, grief, and loss due to the transient nature of foster care, but little is known about how birth children manage this loss. This paper reports findings from a qualitative study that examined the retrospective experiences of 15 adult birth children of foster carers (aged between 18 and 28 years) in Ireland. Findings suggest that birth children experience grief and loss when foster children leave their families. They report experiencing a range of emotional responses such as guilt, blame, and sadness. A reluctance to discuss their emotional responses with either their parents or foster care professionals was also reported. Instead, birth children developed strategies to manage the loss, such as distancing themselves from the foster care process. The study highlights the importance of social workers and foster carers explaining to birth children why foster children are leaving and, where possible, maintaining contact between birth children and foster children. Additionally, findings indicate the need for birth children to have safe nonjudgmental spaces to discuss their emotional reactions to loss.     

Working With Parents of Gender-Variant Children: Using Social Action as an Emancipatory Research Framework

This article examines and reflects on the methodology used in a research project that involved group work activities with parents of gender-variant children. Gender variance in children remains a topic people talk little about. Discussions about people who express themselves differently from the social norms attached to their birth sex, to a large extent, remain rarely discussed. They challenge a society organized largely on the basis of a binary understanding of identity, one that belongs to either male or female. This article discusses the concept of oppression as being central to the experiences of gender-variant children and young people and their parents, and it proposes social action research as a compatible and appropriate research framework for exploring their experiences. We describe the research process, identify its achievements, and explore issues that had to be confronted. We suggest that traditional research structures may benefit from being revisited in order to allow emancipatory research to more fully achieve its potential for both research and social action.     

Making available information from studies sponsored by the pharmaceutical industry: some current practices

Since the web-based registry ClinicalTrials.gov was launched on 29 February 2000, the pharmaceutical industry has made available an increasing amount of information about the clinical trials that it sponsors. The process has been spurred on by a number of factors including a wish by the industry to provide greater transparency regarding clinical trial data; and has been both aided and complicated by the number of institutions that have a legitimate interest in guiding and defining what should be made available. This article reviews the history of this process of making information about clinical trials publicly available. It provides a reader's guide to the study registries and the databases of results; and looks at some indicators of consistency in the posting of study information.     

A DISCRETE-IN-TIME PROBABILISTIC INVENTORY MODEL FOR DETERIORATING ITEMS

A probabilistic scheduling-period inventory model continuous in units and discrete in time is developed for deteriorating items where deterioration is assumed to be a constant fraction of the on-hand inventory. The model is developed under the conditions of instantaneous delivery and no shortages. An example followed by sensitivity analysis is given to illustrate the derived results.     

Gender,Spousal Caregiving,and Depression: Does Paid Work Matter?

Studies have shown that spousal caregiving leads to psychological distress, but few have analyzed the moderating effect of paid work. Using the 2000 to 2012 Health and Retirement Study and two‐stage least squares regression models, this study found that caregiving increased women's and men's depressive symptoms. Ordinary least squares models showed that caregiving had more adverse effects on women's mental health than on men's, but these differences were eliminated in two‐stage least squares models that accounted for the bidirectional effects of depression and caregiving. The current study also found that for women, part‐time work attenuated the depressive effect of spousal caregiving, whereas for men, part‐time work exacerbated it. These gender differences persisted even for intensive spousal caregivers. The authors suggest that caregiving women who work part‐time may benefit from work‐related resources. Caregiving men who work part‐time, however, may feel distressed, as their work–family experiences conflict with traditional gender norms.
