Whether people seek help depends on their estimations of both the likelihood and the value of getting it.Although past research has carefully examined how accurately help-seekers predict whether their helprequests will be granted, it has failed to examine how accurately help-seekers predict the value of thathelp, should they receive it. In this paper, we focus on how accurately help-seekers predict a key determinantof help value, namely, helper effort. In four studies, we find that (a) helpers put more effort intohelping than help-seekers expect (Studies 1–4); (b) people do not underestimate the effort others willexpend in general, but rather only the effort others will expend helping them (Study 2); and (c) thisunderestimation of help effort stems from help-seekers’ failure to appreciate the discomfort—in particular,the guilt—that helpers would experience if they did not do enough to help (Studies 3 & 4)

While sharing intellectual ancestry, organizational ecology and institutionalism are rarely used conjointly to explain population dynamics. A rapprochement would nevertheless be fruitful, as the parsimonious models developed by ecologists are better able to explain organizational founding and failure when enriched with institutional variables. We present a meta-analysis of density dependence theory, which predicts a non-monotonic relationship between population density and organizational vital events. We show that ecology and institutionalism are ‘better together’ by extending this ecological framework in four institutionalism-inspired ways. First, we show that the effects of density on organizational vital rates are moderated by two conceptions of time: ecological ‘clocks’ and institutional ‘eras’. Second, we argue that the socio-political legitimacy of organizational forms, a concept with strong institutional roots, exacerbates density-related founding while attenuating failure. Third, we illustrate how the emergence of prototypical categories in organizational fields can increase the magnitude of density effects. Fourth, we highlight how these socio-political legitimacy and categorization effects are conditioned by ecological clock time. We close by proposing a concise agenda for future research, aimed at finding a better balance between the generality and explanatory power of our most trusted organizational theories. © 2017, © The Author(s) 2017

Effects of inter-group status on the pursuit of intra-group status

Mots clés : Inter-group status; Intra-group status; Cooperation; Competition

This research examines how the status of one’s group influences intra-group behavior and collective outcomes. Two experiments provide evidence that, compared to members of low-status groups, members of high-status groups are more concerned about their intra-group standing, which in turn can increase both the likelihood of competitive and cooperative intra-group behavior. However, whether the desire for intra-group standing manifests via competitive versus cooperative behavior depends on the relevance of the task to the group’s inter-group standing. When the task is not clearly relevant to the group’s status, members of high-status groups are more likely to engage in competitive behavior out of a desire to manage their intra-group status, which, in turn, leads to less desirable collective outcomes. However, when the group’s status is at stake, members of high-status groups seek intra-group status via cooperative behavior, leading to better collective outcomes.

My kids, your kids, our kids: What parents and the public want from schools

Background/Context: School choice reforms could strengthen parents' influence on school behaviors, since schools must appeal to parents in order to operate. If parents' desires for schools differ from the broader public's desires for schools, then schools might pursue different goals and activities in systems emphasizing school choice. One popular hypothesis is that schoolchoosing parents, more than the public, want schools to prioritize their own students' private interests over more collective social, economic, and political interests. Purpose/Objective: We compare parents' desires for their own children's schools with the U.S. public's desires for public schools. We make these comparisons with respect to the abstract goals that schools pursue, as well as schools' more tangible behaviors. Population/Participants/Subjects: We administered an online survey to nationally representative samples of parents and adults. We administered a second online survey to a national sample of adults. Intervention/Program/Practice: The article consists of two studies. Study 1 compares parents' and the public's beliefs about which abstract goals schools should prioritize. Respondents were randomly assigned to consider either schools in their community, schools around the country, or, if they had children, their own children's schools. They chose from goals that prioritized their students' professional achievement ("Private Success"), the economy's needs ("Shared Economic Health"), and more collective social and political needs ("Democratic Character"). Study 2 compares parents' and the public's beliefs about how schools should actually behave. Respondents were randomly assigned to consider either schools in their community, schools around the country, or their own children's schools. We asked about the basic structure and content of the school day, how schools should teach, and how to evaluate school performance. Research Design: The studies consist of randomized experiments and related statistical analysis. Findings/Results: We find remarkably little difference between parents' desires for their children's schools and the public's desires for public schools. This is true both for the abstract goals that schools pursue and for schools' more tangible behaviors. Conclusions/Recommendations: Our findings suggest that the hypothesis that parents want schools to focus on their students' private success at the expense of more collective goals is oversimplified. It may be, for example, that parents want their children to be well rounded in ways that also serve more collective social, political, and economic interests. We observe divisions in Americans' views of the goals that schools should pursue, but these divisions are more connected to their political affiliation than parent status (with Republicans more focused than Democrats on Private Success)

Optimizing Multi-Team System Behaviours: Insights from Modelling Team Communication

To better manage behavioural operations in project management, we demonstrate the value of quantitative model-based approaches in examining behaviours and generating insights for managerial research and practice. We focus on organizational members’ behaviours and interactions on large-scale projects using multi-team systems (MTS). While MTS invoke different behaviours than simpler team systems, research insights have lagged on MTS due to the complexity and resource intensity of capturing the multitude of behaviours and interactions by human subjects in real-world situations. Thus, MTS provides an apt context to demonstrate the mechanics of mathematically modelling human behaviour and conducting virtual experiments via mixed-integer linear optimization to understand the way to meet operational objectives. Virtual experimentation is used to explore communication behaviours that unfold under different levels of project complexity and interdependence when time, cost, and quality operational objectives are considered independently or collectively. The results suggest that the type of communication plan set by project managers needs to change according to project attributes and objectives (maximize quality, minimize cost or minimize time). Moreover, this paper demonstrates the benefits of using operations research methods to assess behavioural patterns in an operational setting and establish propositions for targeted research in the field. In conclusion, benefits and limitations are put forth about the way Behavioural OR expands the traditional toolkit of human subject researchers in operations and beyond.
