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.     

Relationship Between Private Religious Activity and Physical Functioning in Older Adults

This study sought to further understand the relationship between physical functioning and use of private religious activity in older adults. Subjects were age 65 or older from urban and rural counties in North Carolina who participated in the Duke University Established Populations for Epidemiologic Studies of the Elderly (Duke/EPESE). A total of 3,851 subjects responded to a question that inquired about their use of prayer, meditation, or Bible reading in 1986. Their response was correlated to number of impairments in activities of daily living (ADLs) (n = 3,791). Subjects who indicated use of private religious activity either dailyor neverhad the greatest number of impairments. Those who prayed or meditated one time per weekhad the least number of impairments. This cross-sectional finding is explained in terms of both changes in private religious activity in response to increasing physical disability and changes in physical disability in response to private religious activity. Previous research has found that prayer is often used as an effective coping mechanism with various sicknesses and chronic conditions. Further studies are needed to examine older individuals' health over time and evaluate their use of private religious activity to see its impact over time on physical disability.     

Effects of Considering Who and Why the Defendant Attacked1

Some people who are accused of a crime admit to the act, but provide an excuse. The effects of an excuse's self‐inflictedness level (high, moderate, or low) and the type of victim attacked (one partially responsible for the defendant's excusing condition, or innocent victim) were investigated. After a pretest (N= 26) to choose stimuli, participants (N= 220) read a scenario in which a male attacks another and then, once on trial, gives an excuse for his act. Those giving highly vs. less self‐inflicted excuses were more likely to receive a guilty verdict, received higher guilt level ratings, and tended to receive longer sentences; those who hurt an innocent vs. a partially responsible victim were more likely to be found guilty. In addition, the defendant's sentence was influenced by both the type of victim and the self‐inflictedness level of the excuse. The influence of perceived responsibility for an act on jurors' decisions is discussed
