Were the “Pioneer” Clinical Ethics Consultants “Outsiders”? For Them,Was “Critical Distance” That Critical?

“Clinical ethics consultants” have been practicing in the United States for about 50 years. Most of the earliest consultants—the “pioneers”—were “outsiders” when they first appeared at patients' bedsides and in the clinic. However, if they were outsiders initially, they acclimated to the clinical setting and became “insiders” very quickly. Moreover, there was some tension between traditional academics and those doing applied ethics about whether there was sufficient “critical distance” for appropriate reflection about the complex medical ethics dilemmas of the day if one were involved in the decision making. Again, the pioneers deflected concerns by identifying and instituting safeguards to assure professional objectivity in clinical ethics consultation services. One might suggest that in moving inside and establishing normative practices, the pioneer clinical ethics consultants anticipated adoption of their routines and professionalization of the field.     

Toward the development of a feature-space representation for a complex natural category domain

This article reports data sets aimed at the development of a detailed feature-space representation for a complex natural category domain, namely 30 common subtypes of the categories of igneous, metamorphic, and sedimentary rocks. We conducted web searches to develop a library of 12 tokens each of the 30 subtypes, for a total of 360 rock pictures. In one study, subjects provided ratings along a set of 18 hypothesized primary dimensions involving visual characteristics of the rocks. In other studies, subjects provided similarity judgments among pairs of the rock tokens. Analyses are reported to validate the regularity and information value of the dimension ratings. In addition, analyses are reported that derive psychological scaling solutions from the similarity-ratings data and that interrelate the derived dimensions of the scaling solutions with the directly rated dimensions of the rocks. The stimulus set and various forms of ratings data, as well as the psychological scaling solutions, are made available on an online website (https://osf.io/w64fv/) associated with the article. The study provides a fundamental data set that should be of value for a wide variety of research purposes, including: (1) probing the statistical and psychological structure of a complex natural category domain, (2) testing models of similarity judgment, and (3) developing a feature-space representation that can be used in combination with formal models of category learning to predict classification performance in this complex natural category domain.     

Interaction Effects of Neighborhood Disadvantage and Individual Social Support on Frequency of Alcohol Use in Youth Living with HIV

Youth living with HIV (YLH) experience multiple disease‐related stresses along with the same structural and developmental challenges faced by their uninfected peers; alcohol use among YLH represents a risk behavior by virtue of potential effects on youth health and increased likelihood of engaging in unprotected sex while drinking alcohol. Research aimed at better understanding the interplay of individual‐ and neighborhood‐level influences on alcohol use for YLH is needed to inform interventions. This study examined whether socioeconomic disadvantage (SED) and social support influence, independently and through interaction, alcohol use in YLH. Data from the Adolescent Medicine Trials Network for HIV/AIDS Interventions (ATN) consisted of YLH across 538 neighborhoods in the United States who acquired HIV behaviorally. Neighborhood‐specific data were compiled from the 2010 U.S. Census Bureau and matched with individual‐level data from the ATN (N = 1,357) to examine effects that contribute to variation in frequency of alcohol use. Other drug use, being male, being non‐Black, and older age were associated with greater alcohol use. Higher social support was negatively associated with alcohol use frequency. A cross‐level interaction indicated that the association found between decreasing social support and increasing alcohol use frequency was weakened in areas with lower SED. Implications are discussed.     

Harmonious passions support cognitive resources

Passionate activities can be a source of pleasure and meaning. According to the Dualistic Model of Passion individuals can have either a harmonious or an obsessive passion for an activity. Where harmonious passions provide positive emotional experience, obsessive passions do not. Fredrickson’s broaden-and-build theory holds that ongoing positive experience have general and lasting cognitive benefits; accordingly this should accrue more strongly to those reporting harmonious passions. In a survey (N = 141), we examined self-reported attention, executive functioning, and life quality and contrast these by individuals’ passion orientation. In a cross-sectional survey we found that harmoniously passionate individuals differed from the obsessively passionate across questionnaire measures of attention, executive functioning, and life quality. We find that these differences correspond well to that which would be predicted on the basis of the broaden-and-build theory, however the observed effects are not large and do not correspond to clinical differences.     

The importance of understanding: Model space moderates goal specificity effects

The three-space theory of problem solving predicts that the quality of a learner's model and the goal specificity of a task interact on knowledge acquisition. In Experiment 1 participants used a computer simulation of a lever system to learn about torques. They either had to test hypotheses (nonspecific goal), or to produce given values for variables (specific goal). In the good- but not in the poor-model condition they saw torque depicted as an area. Results revealed the predicted interaction. A nonspecific goal only resulted in better learning when a good model of torques was provided. In Experiment 2 participants learned to manipulate the inputs of a system to control its outputs. A nonspecific goal to explore the system helped performance when compared to a specific goal to reach certain values when participants were given a good model, but not when given a poor model that suggested the wrong hypothesis space. Our findings support the three-space theory. They emphasize the importance of understanding for problem solving and stress the need to study underlying processes.     

Evaluating the effectiveness of pixelation and blurring on masking the identity of familiar faces

Two experiments are reported that assess how well the identity of highly familiar (famous) faces can be masked from short naturalistic television clips. Recognition of identity was made more difficult by either pixelating (Experiment 1) or blurring (Experiment 2) the viewed face. Participants were asked to identify faces from both moving and static clips. Results indicated that participants were still able to recognize some of the viewed faces, despite these image degradations. In addition, moving images of faces were recognized better than static ones. The practical and theoretical implications of these findings are discussed. Copyright © 2001 John Wiley & Sons, Ltd.     

The Effect of Other-Oriented Values on Decision Making: A Test of Propositions of a Theory of Concern for Others in Organizations

Based on recent theoretical work by Simon (1990, 1993), we proposed that the value of concern for others would reflect a general process whereby individuals place less value on personal outcomes and are less disposed to engage in rational calculations involving costs and benefits. We conducted two studies to examine whether these mechanisms generalize to situations that do not involve helping others. In the first study, persons high in concern for others were less attracted to choices involving the prospect of personal gain and were less discerning about the value and risk involved in making choices than were individuals low in concern for others. The second study showed that positive affective arousal, which is likely to focus attention on personal concerns, moderated the effects observed in the first study. Results suggest that other-oriented values such as concern for others may have a substantial impact on a wide range of organizational processes beyond helping.     

Risk strategy under task complexity: a multivariate analysis of behaviour in a naturalistic setting

This study complements the existing literature on decision-making processes and outcomes in complex settings by exploring the impact of different types of complexity on risk strategies in a naturalistic setting. The study analyses a large sample of decisions made by individuals in UK offcourse betting markets, a fertile environment for observing both a variety of risk strategies and a range of task complexities. Specifically, the investigation focuses on the comparative impacts of complexity defined in terms, respectively, of alternatives and attributes. The results suggest that the risk strategy employed is affected by task complexity. Complexity does not affect the size of risk accepted but alternative- and attribute-based complexity together influence the propensity to accept greater degrees of risk. In addition, the effect of attribute-based complexity on risk taking appears to be modified by the use of risk-hedging strategies. The results are observed to corroborate some earlier work on decision process and outcome; where differences with earlier findings are identified, some possible explanations are offered. © 1998 John Wiley & Sons, Ltd.
