Adaptive Build-up and Breakdown of Trust: An Agent Based Computational Approach

This article employs Agent-Based Computational Economics (ACE) to investigate whether, and under what conditions, trust is viable in markets. The emergence and breakdown of trust is modeled in a context of multiple buyers and suppliers. Agents develop trust in a partner as a function of observed loyalty. They select partners on the basis of their trust in the partner and potential profit, with adaptive weights. On the basis of realized profits, they adapt the weight they attach to trust relative to profitability, and their own trustworthiness, modeled as a threshold of defection. Trust and loyalty turn out to be viable under fairly general conditions.     

In Search of ‘Managerial Work’: Past,Present and Future of an Analytical Category

Based on a comprehensive review of literature, the paper examines how ‘managerial work’ as a fluid analytical category has been approached methodologically, theoretically and empirically for more than 60 years. In particular, it highlights the existence of competing scholarly understandings regarding its nature, performance, meaning and politics. The authors suggest that subsequent empirical investigations have too often worked, methodologically and theoretically, to slot in, and thus effectively reduce, the term to a particular pre‐existing box, rather than exploring open‐endedly the what and how, but also the why of ‘managerial work’ as a distinct mode of situated ordering. Having represented the concept's past and present by identifying four distinct research approaches reflected in representative publications, the authors suggest that more attention should be devoted to a mode of analytical departure that promises to address directly the suggested shortcomings in the literature. Specifically, it is argued that much could be gained if contemporary notions of practice were brought into the study of managerial work. To this end, the authors outline the contours of a practice‐based approach as a sensitizing framework for understanding managerial work by highlighting the situated, relational, sociomaterial, meaning‐making and consequence‐oriented analytical foci the approach suggests, and suggesting a number of conjoint research questions, as well as acknowledging subsequent limitations.     

Trust in American Government: Longitudinal Measurement Equivalence in the ANES, 1964–2008

For over 50 years (1958–2012) the American National Election Studies (ANES) survey has been measuring citizens’ evaluations of the trustworthiness of the “government in Washington”—an indicator that has been widely used to monitor the dynamics of political trust in the US over time. However, a critical assumption in using attitudinal constructs for longitudinal research is that the meaning-and-interpretation of such items should be comparable across groups of respondents at any one point in time and across samples over time. Using multigroup confirmatory factor analysis for ordered-categorical data, we test the measurement equivalence assumption with data collected by the ANES from 1964 to 2008. The results confirm that the ANES’ political trust scale has the same basic factorial structure over time. But for two key items, several threshold parameters were found to be different across time points, indicating that the meaning-and-interpretation of these questions, and especially the question about whether the government in Washington wastes money that people pay in taxes, varies significantly over time.

     

Letter to the Editor: Respecting the Plurality of Value and the Messiness of Scientific Practice

Evaluations of authorship and recommendations for authorship policies best heed the plurality of valuation cultures that traverse scientific practices and respect the messiness of scientific practices, for those are reflected in authorship and authorship sequence decisions.     

Managing The Lactating Body: The Breast-Feeding Project and Privileged Motherhood

Drawing on interviews with twenty-five mostly white, educated, work-force experienced and class-privileged mothers, this paper explores how these women construct the lactating body as a carefully managed site and breast-feeding as a project—a task to be researched, planned, implemented, and assessed, with reliance on expert knowledge, professional advice, and consumption. The framing of breast-feeding as a project contrasts with the emphases on pleasure, embodied subjectivity, relationality, and empowerment that characterizes much of the recent breast-feeding literature across the humanities and social sciences. I argue that the project frame sheds light on the amount of work and self-discipline involved in compliance with broader middle-class mothering standards set in the consumerist, technological, medicalized, and professionalized contexts that shape parenting in late capitalist America.

Myths of Women and Their Reflection in a Therapy Group

One essential dilemma for modern clinical social work involves the relationship between the processes taking place inside the self and the social, cultural, and political developments affecting a person from the outside. The group-analysis approach focuses on four levels of relationships and communication within the group, among others a primordial level of shared myths, archetypical images, and the collective unconscious as an important component of psychotherapy. This article describes group-analysis therapy with women, analyzing a therapeutic process that used social myths to explore the formative institutionalization processes participants had undergone, thereby expanding themselves, growing, and changing.

Macro-Economic Factors in Credit Risk Calculations: Including Time-Varying Covariates in Mixture Cure Models

The prediction of the time of default in a credit risk setting via survival analysis needs to take a high censoring rate into account. This rate is because default does not occur for the majority of debtors. Mixture cure models allow the part of the loan population that is unsusceptible to default to be modeled, distinct from time of default for the susceptible population. In this article, we extend the mixture cure model to include time-varying covariates. We illustrate the method via simulations and by incorporating macro-economic factors as predictors for an actual bank dataset.     

All for one or one for all? Authorship and the cross-sectoral valuation of credit in nutrition science

The passionate pursuit of authorships is fuelled by the value they represent to scholars and scientists. This article asks how this value differs across scientists and how these different processes of valuation inform authorship articulation, strategies, and publication behavior in general. Drawing from a qualitative analysis of authorship practices among nutrition scientists employed at universities, contract research organizations, and in food industry, I argue that two different modi operandi emerge when it comes to authorship. These different ways of working produce different collaborative approaches, different credit distribution strategies amongst collaborators, and different value placed upon (the pursuit of) authorship. These different valuation processes are neither explicit nor recognizable to those reading (and judging) author lists. As a consequence, in the politics of authorship, the names standing atop a scientific publication in nutrition science represent different types of value to both the individuals and employing organizations.     

Who does not cut down? Comparing characteristics and drinking motives of drinkers and abstainers during the exam periods

Objective: Drinking alcohol during the exams can affect academic performance and future career options, but is rarely investigated. Drinking motives, sociodemographics and personality characteristics are investigated in nonabstainers and weekly drinkers during the exams. Participants: 7,181 Belgian university students who anonymously responded to an email invitation to an online survey. Methods: Logistic regressions and mixed design analysis of variance on cross-sectional data. Results: One-third of the students continued drinking during the exams, with 40% drinking weekly. Nonabstainers were mainly men, elder, internally motivated when drinking, and housed with parents or independently. Weekly drinkers were similar, except mainly housed in student apartments or independently. Personality characteristics were nonsignificant. All drinking motives were less pronounced during the exams, with smaller differences for internal motives. Conclusions: Mainly linked to internal drinking motives, drinking during the exams in higher education is underestimated. The characteristics and motives of students doing so can be used in future interventions.
