Military Influence Tactics: Lessons Learned in Iraq and Afghanistan

10 PagesWhen deployed U.S. soldiers attempt to influence the attitudes, beliefs, or behaviors of civilians, success can save lives and failure can be deadly. Survey data from 228 military personnel with deployment experience to Iraq and Afghanistan revealed that in a challenging wartime environment, empathy, respect, prior relationships, and familiarity with influence targets predicted success in cross-cultural influence attempts. Influence techniques involving resources and positive feelings were used more commonly in relatively successful influence attempts; negative tactics were used more commonly in unsuccessful attempts

A quasi-Monte Carlo comparison of developments in parametric and semi-parametric regression methods for heavy-tailed and non-normal data : with an application to healthcare costs

We conduct a quasi‐Monte‐Carlo comparison of the recent developments in parametric and semiparametric regression methods for healthcare costs, both against each other and against standard practice. The population of English National Health Service hospital in‐patient episodes for the financial year 2007–2008 (summed for each patient) is randomly divided into two equally sized subpopulations to form an estimation set and a validation set. Evaluating out‐of‐sample using the validation set, a conditional density approximation estimator shows considerable promise in forecasting conditional means, performing best for accuracy of forecasting and among the best four for bias and goodness of fit. The best performing model for bias is linear regression with square‐root‐transformed dependent variables, whereas a generalized linear model with square‐root link function and Poisson distribution performs best in terms of goodness of fit. Commonly used models utilizing a log‐link are shown to perform badly relative to other models considered in our comparison

A Tripartite Model of Group Identification: Theory and Measurement

Group identification is defined as member identification with an interacting group and is distinguished conceptually from social identity, cohesion, and common fate. Group identification is proposed to have three sources: cognitive (social categorization), affective (interpersonal attraction), and behavioral (interdependence). Inconsistent use of the term and problematic measurement mar existing literature on group identity and group identification. A new group identification scale, composed of three subscales that match the tripartite model for the cognitive, affective, and behavioral sources, is presented and its psychometric properties described.Yeshttps://us.sagepub.com/en-us/nam/manuscript-submission-guideline

Evaluation Beyond Usability

The evaluation of research artefacts is an important step to validate research contributions. Sub-disciplines of HCI often pursue primary goals other than usability, such as Sustainable HCI (SHCI), HCI for development, or health and wellbeing. For such disciplines, established evaluation methods are not always appropriate or sufficient, and new conventions for identifying, discussing, and justifying suitable evaluation methods need to be established. In this paper, we revisit the purpose and goals of evaluation in HCI and SHCI, and elicit five key elements that can provide guidance to identifying evaluation methods for SHCI research. Our essay is meant as a starting point for discussing current and improving future evaluation practice in SHCI; we also believe it holds value for other subdisciplines in HCI that encounter similar challenges while evaluating their research

Many Labs 5:Testing pre-data collection peer review as an intervention to increase replicability

Replication studies in psychological science sometimes fail to reproduce prior findings. If these studies use methods that are unfaithful to the original study or ineffective in eliciting the phenomenon of interest, then a failure to replicate may be a failure of the protocol rather than a challenge to the original finding. Formal pre-data-collection peer review by experts may address shortcomings and increase replicability rates. We selected 10 replication studies from the Reproducibility Project: Psychology (RP:P; Open Science Collaboration, 2015) for which the original authors had expressed concerns about the replication designs before data collection; only one of these studies had yielded a statistically significant effect (p < .05). Commenters suggested that lack of adherence to expert review and low-powered tests were the reasons that most of these RP:P studies failed to replicate the original effects. We revised the replication protocols and received formal peer review prior to conducting new replication studies. We administered the RP:P and revised protocols in multiple laboratories (median number of laboratories per original study = 6.5, range = 3?9; median total sample = 1,279.5, range = 276?3,512) for high-powered tests of each original finding with both protocols. Overall, following the preregistered analysis plan, we found that the revised protocols produced effect sizes similar to those of the RP:P protocols (?r = .002 or .014, depending on analytic approach). The median effect size for the revised protocols (r = .05) was similar to that of the RP:P protocols (r = .04) and the original RP:P replications (r = .11), and smaller than that of the original studies (r = .37). Analysis of the cumulative evidence across the original studies and the corresponding three replication attempts provided very precise estimates of the 10 tested effects and indicated that their effect sizes (median r = .07, range = .00?.15) were 78% smaller, on average, than the original effect sizes (median r = .37, range = .19?.50)

Stability, Bistability, and Instability in Small Group Influence Patterns

11 PagesThree models of change and continuity in group structure are tested using existing longitudinal data on 20 small groups. Groups met face to face or via a computer-mediated communication system for 13 weeks. Computer-mediated groups fit the robust equilibrium pattern best, with initial fluctuations in the influence hierarchy followed by a more stable structure that persisted despite changes in operating conditions. Face-to-face groups fit a bistable punctuated equilibrium pattern best, retaining their initial influence structure until an environmental cue triggered a shift. Contrary to die predictions of this model for radical change, adjustments were modest. Poor performance on tasks failed to trigger changes predicted by the adaptive response model, probably because outcomes were not very important to group members

Evolutionary Perspectives on Religion: An Overview and Synthesis

19 PagesReligion is a cultural universal that has puzzled evolutionists since Darwin. The moral, social, emotional, and explanatory components that make up complex religious systems offer both evolutionary benefits and costs. Evolutionists who propose functional accounts of religion argue that it offers adaptive benefits that outweigh the costs. Theorists who propose nonfunctional accounts view religion as a byproduct of interactions among nonreligious cognitive adaptations and environments. Others argue that religion evolved via memetic transmission, which allows maladaptive features to persist. These maladaptive features may be anachronisms that were functional in the past but are detrimental to fitness in modern contexts. A thorough review reveals that work guided by these different perspectives is driven by divergent research questions that ultimately complement one another to offer a more comprehensive evolutionary account of the complexity, variety, and durability of religious belief and behavior

Reengineering Gender: Relations in Modern Militaries: An Evolutionary Perspective

20 pagesThis article presents an evolutionary framework for understanding the sexual assault of women in the military. We specify the evolutionary underpinnings of tensions among heterosexual males, among heterosexual females, and between males and females and discuss how these tensions have played out in the strongly gendered context of warrior culture. In the absence of cultural interventions that take into account deep-seated conceptions of women in the military as unwelcome intruders, sexual resources for military men, or both, military women operate in an environment in which sexual assault may be deployed to enact and defend traditional military structures. We discuss how unit norms are likely to affect the choice of strategies by men and by women and how the resulting behaviors—including celibacy, consensual sex, and sexual assault—should affect horizontal and vertical unit cohesion. The framework is intended to guide future data collection in theoretically coherent ways and to inform the framing and enforcement of policies regarding both consensual and non-consensual sex among military personnel
