A comparison of random balance and two-stage group screening designs: A case study

In this paper we focus on the problem of supersaturated (fewer runs than factors) screening experiments. We consider two major types of designs which have been proposed in this situ¬ation: random balance and two-stage group screening. We discuss the relative merits and demerits of each strategy. In addition, we compare the performance of these strategies by means of a case study in which 100 factors are screened in 20,42,62, and 84 runs.     

From primacy to purpose commitment: How emerging profit-with-purpose corporations open new corporate governance avenues

This paper aims at contributing to corporate governance theory by developing a model of governance that takes into account a recent legal innovation: the introduction of purpose-driven legal business forms in the corporate law of several countries. Current debates in such theory oppose models that grant “primacy” (i.e., ultimate control rights) to different constituencies. The resulting uncertainty proves problematic in the face of new, urgent social and environmental stakes that are difficult to represent in traditional governance bodies. Newly adopted profit-with-purpose corporate forms' introduction of a “purpose” in corporate contracts renews these debates. We show that through the “purpose commitment” model it enables, the distribution of control rights in the governance system is decoupled from the objectives assigned to the corporation. This new approach renews the formal role of management, and corporations’ accountability to society. We explore the theoretical, practical, and political consequences of this new model.     

Response to Fugard and Hines

ABSTRACT

This article replies to the responses to my article on “Sex and the Census: Why surveys should not conflate sex and gender identity“. Fugard conflates sex itself with the characteristics associated with sex, such as finger length ratios, leading to the erroneous implication that binary sex is not a useful explanatory variable. Hines fundamentally misrepresents my article, claiming that I have argued against asking respondents to the 2021 Census about their gender identity. In fact I make clear that information on gender identity is useful, but cannot replace data on sex. Muddling gender identity and sex will lead to the collection of inaccurate data on both. Hines resorts to a series of ad hominem attacks rather than engaging with the substance of the argument. Neither Fugard nor Hines is able to give a reason why we should not seek to collect accurate data on sex in the census or elsewhere.     

Impulsivity as a Risk Factor for HIV Transmission in Men Who Have Sex with Men: A Delay Discounting Approach

Delay discounting (DD) is a measure of impulsivity that describes the subjective decline in value of a consequence as the delay to that consequence increases. We sought to assess whether the results of a monetary DD task would be predictive of sexual risk-taking in a group of Internet-using men who have sex with men (MSM). 1402 participants completed an online survey that included questions about the participant’s demographics, sexual history and behavior, drug use, sexual compulsivity, and a monetary DD task. High DD was associated with increased odds of reporting >2 UAI partners in the past 12 months [aOR = 1.5 (1.1–2.1)]. Future studies should examine the utility of DD as a predictor of risky sexual behavior, as well as explore the possibility of HIV prevention interventions targeting DD.     

Evolution of Quality: First Fifty Issues of Production and Operations Management

Many contributions have been made to the field of quality since the inaugural issue of Production and Operations Management in 1992. The first issue called for more research and teaching on TQM, which resulted in two special issues dedicated to TQM. Many other articles related to quality have also been published in the first fifty issues of the journal on topics ranging from technical methods to the Baldrige Award and ISO 9000. As we review these articles, we assess their contribution and the progression of the field of quality. Although past research has advanced our understanding of quality, there still exists many research opportunities in developing more theory, using additional research methodologies, and studying emerging topics in this field.     

Consumer Capital Market Constraints and Guaranteed Renewable Insurance

This paper analyzes a market in which individuals can purchase guaranteed renewable insurance policies to insure against the risk of loss in the current period and the risk of an increased probability of loss. Individuals who cannot borrow will purchase partially guaranteed renewable insurance at most. Relatively impatient individuals may purchase policies with no guaranteed renewability features. Without borrowing, the results are similar regardless of whether consumers can save.     

Predicting Adolescent Autonomy from Parents: Relationship Connectedness and Restrictiveness

This study examined the extent to which adolescents'behavioral autonomy was predicted by several aspects of the parent-youth relationship that are encompassed by the general constructs connectedness and restrictiveness. Both of these general relationship constructs are composed of more specific social-psychological predictors consisting of parental behaviors, parent-adolescent authority dimensions, and indicators of family ties. A total of 657 adolescents (mean age = 16.3 years) and 753 parents responded to self-report questionnaires. Hierarchical multiple regression analyses were used to test the hypotheses from both the adolescents'and parents'perspectives in separate models. Many of the predictions were confirmed, indicating that adolescent behavioral autonomy often develops within contexts of relationship connectedness, such as continuing parent-youth authority and supportiveness. Moreover, as expected, youthful autonomous behavior was inhibited by such aspects of relationship restrictiveness as punitive behavior and the perceived coercive abilities of parents.     

When children work: implications for youth, society and organizations

We review the literature on youth employment. In particular, we highlight data suggesting youth is not a homogenous group, and that employment is not a homogenous experience for young workers. Demographic and motivational differences within the group categorized as 'youth', as well as differences in the context and quality of youth employment experiences, are shown to have substantial implications for research, policy and organizations.
