Missional Congregations as Public Companions with God in Global Civil Society: Vocational Imagination and Spiritual Presence

This article explores the intersection of missional ecclesiology and civil society studies and proposes that the Holy Spirit is calling emerging missional congregations to the vocation of public companions with God in global civil society. This congregational vocation of public companion entails four dimensions of missional congregations’ spiritual presence within civil society: perichoretic communion, prophetic speech, sapiential wisdom, and pacific action.     

The Utility of Cognitive Plausibility in Language Acquisition Modeling: Evidence From Word Segmentation

The informativity of a computational model of language acquisition is directly related to how closely it approximates the actual acquisition task, sometimes referred to as the model's cognitive plausibility. We suggest that though every computational model necessarily idealizes the modeled task, an informative language acquisition model can aim to be cognitively plausible in multiple ways. We discuss these cognitive plausibility checkpoints generally and then apply them to a case study in word segmentation, investigating a promising Bayesian segmentation strategy. We incorporate cognitive plausibility by using an age‐appropriate unit of perceptual representation, evaluating the model output in terms of its utility, and incorporating cognitive constraints into the inference process. Our more cognitively plausible model shows a beneficial effect of cognitive constraints on segmentation performance. One interpretation of this effect is as a synergy between the naive theories of language structure that infants may have and the cognitive constraints that limit the fidelity of their inference processes, where less accurate inference approximations are better when the underlying assumptions about how words are generated are less accurate. More generally, these results highlight the utility of incorporating cognitive plausibility more fully into computational models of language acquisition.     

Voice and Culture: A Prospect Theory Approach

The present study examines the congruence of individuals' minimum preferred amounts of voice with the prospect theory value function across nine countries. Accounting for previously ignored minimum preferred amounts of voice and actual voice amounts integral to testing the steepness of gain and loss functions explicated in prospect theory, we use curve fitting to show that ratings of procedural justice fit prospect theory's value function specifically. Further, we investigate the form of this function across nine countries that range in power distance. Results suggest that the form of the value function is congruent with prospect theory, showing an S‐shaped curve that is steeper in the loss than in the gain domain. Further, this pattern is similar across countries. Theoretical and practical implications of these results for both decision making and organizational justice are discussed.

Software Piracy in Research: A Moral Analysis

Researchers in virtually every discipline rely on sophisticated proprietary software for their work. However, some researchers are unable to afford the licenses and instead procure the software illegally. We discuss the prohibition of software piracy by intellectual property laws, and argue that the moral basis for the copyright law offers the possibility of cases where software piracy may be morally justified. The ethics codes that scientific institutions abide by are informed by a rule-consequentialist logic: by preserving personal rights to authored works, people able to do so will be incentivized to create. By showing that the law has this rule-consequentialist grounding, we suggest that scientists who blindly adopt their institutional ethics codes will commit themselves to accepting that software piracy could be morally justified, in some cases. We hope that this conclusion will spark debate over important tensions between ethics codes, copyright law, and the underlying moral basis for these regulations. We conclude by offering practical solutions (other than piracy) for researchers.     

Stakeholder Opinions and Ethical Perspectives Support Complete Disclosure of Incidental Findings in MRI Research

How far does a researcher’s responsibility extend when an incidental finding is identified? Balancing pertinent ethical principles such as beneficence, respect for persons, and duty to rescue is not always straightforward, particularly in neuroimaging research where empirical data that might help guide decision making are lacking. We conducted a systematic survey of perceptions and preferences of 396 investigators, research participants, and Institutional Review Board members at our institution. Using the partial entrustment model as described by Richardson, we argue that our data supports universal reading by a neuroradiologist of all research MRI scans for incidental findings and providing full disclosure to all participants.     

Violence prevention: Program effects on urban preschool and kindergarten children

This study compares the effectiveness of a violence prevention program with young, at-risk children in two settings. Preschool and kindergarten students, residing in Chicago public-housing developments, participated in a 28-session intervention. Knowledge, behavior problems, and social skills were assessed at pretest and posttest, based on child interviews, teacher ratings, and behavioral observations. Findings suggest that both preschool and kindergarten children demonstrated significant gains in knowledge, based on interview scores, and significant decreases in problem behaviors, based on behavioral observations; however, teacher ratings did not change significantly across time. The discrepancy in findings is explored and implications are discussed.     

Highly correlated stimuli do not necessarily facilitate the measurement of unconscious perception: Exclusion failure is hard to find in forced-choice tasks

Persaud and McLeod (2008) report that unconscious perception is easier to measure with forced-choice exclusion tasks when the stimuli are highly similar, such as choosing between the letters ‘h’ and ‘b’. The high degree of stimulus similarity may decrease conscious awareness of the target stimuli while leaving unconscious cognition intact. The present experiments used forced-choice exclusion tasks (i.e., choosing the opposite of a masked target stimulus) with the aim of replicating these findings. No evidence of relevant perception – either conscious or unconscious – was obtained with short duration targets. The forced-choice exclusion task was correctly performed at longer target durations (25 ms and higher), which suggests conscious perception of the target stimuli. We conclude that increasing stimulus similarity does not reliably produce exclusion failure effects and does not appear to facilitate the measurement of unconscious cognition.
