The impact of salient self-identities on relative deprivation and action intentions

Salient self-identities and their impact upon feelings of relative deprivation (RD) and subsequent action intentions were examined. Eight experimental conditions (Personal/Group Salience × Large/Small Intragroup Inequalities × Large/Small Intergroup Inequalities) were created utilizing a role-play design. Significant main effects for both salience and social inequalities were found to influence both RD and action intentions. In accordance with self-categorization theory, when group compared to personal identities were made salient, stronger feelings of group RD and greater likelihood of collective action intentions were reported. Alternatively, when personal compared to group identities were made salient, greater likelihood of individual actions were reported. In accordance with relative deprivation theory, when intergroup inequalities were large compared to small, stronger feelings of group RD and less likelihood of collective action were reported. Alternatively, when intragroup inequalities were large compared to small, stronger feelings of personal RD were reported.     

Further evidence for veridical perception during near-death experiences

We briefly survey research designed to validate alleged out-of-body perceptions during near-death experiences. Most accounts of this kind that have surfaced since Michael Sabom's work are unsubstantiated self-reports or, as in claims of visual perception of blind persons, completely undocumented or fictional, but there have been some reports that were corroborated by witnesses. We briefly present and discuss three new cases of this kind.     

Saccadic overhead: Information-processing time with and without saccades

Information-processing time was compared for serial and spatially distributed visual presentations with performance measures that permit the separation of total time into its during-display and post-display components. For all subjects, there was a significant saccadic overhead, that is, less time was required with the serial format, which allowed data access without eye movements. However, the magnitude of the overhead decreased as task complexity increased. All subjects were able to exercise some control over the distribution of total processing time, trading off short during-display times with longer post-display times and vice versa.     

Contributions of empirical research to medical ethics

Empirical research pertaining to cardiopulmonary resuscitation (CPR), clinician behaviors related to do-not-resuscitate (DNR) orders and substituted judgment suggests potential contributions to medical ethics. Research quantifying the likelihood of surviving CPR points to the need for further philosophical analysis of the limitations of the patient autonomy in decision making, the nature and definition of medical futility, and the relationship between futility and professional standards. Research on DNR orders has identified barriers to the goal of patient involvement in these life and death discussions. The initial data on surrogate decision making also points to the need for a reexamination of the moral basis for substituted judgment, the moral authority of proxy decision making and the second-order status of the best interests standard. These examples of empirical research suggest that an interplay between empirical research, ethical analysis and policy development may represent a new form of interdisciplinary scholarship to improve clinical medicine.     

Angular homeostasis: III. The formalism of discrete orbits in ontogeny

The formal properties of orbits in a plane are explored by elementary topology. The notions developed from first principles include: convex and polygonal orbits; convexity; orientation, winding number and interior; convex and star-shaped regions. It is shown that an orbit that is convex with respect to each of its interior points bounds a convex region. Also, an orbit that is convex with respect to a fixed point bounds a star-shaped region. Biological considerations that directed interest to these patterns are indicated, and the implications of the prospect of higher orders of star-shapedness mentioned.     

Social Support and Depression in Rheumatoid Arthritis: A One-Year Prospective Study1

Previous research on patients with rheumatoid arthritis (RA) has suggested that social support is beneficial for helping patients to adjust psychologically to the chronic and unpredictable episodes of pain. This study addresses whether support buffers the adverse effects of arthritis pain or whether support results in a decrease in the severity of pain regardless of pain levels in 233 RA patients. The results indicated that patients who reported higher satisfaction with their emotional support when experiencing higher levels of pain were less likely to be depressed than patients who do not perceive such support. The results were obtained after controlling the effects of demographic variables, functional disability variables, and the direct effects of pain and social support. However, moderating effects of emotional support were not found when this relationship was examined over a 6-month period. Rather, causal modeling suggested that both pain and emotional support contributed to a change in depression over two 6-month intervals. The results also suggested that depression may have an adverse effect on change in emotional support over a similar time frame.     

Reactive and proactive aggression in childhood: Relations to peer status and social context dimensions

Although there has been an accumulation of evidence to suggest a link between peer-directed aggression and social rejection, little attention has been given to the relations between specific subtypes of aggressive behavior and social rejection. The purpose of this investigation was to examine the relations between two subtypes of aggressive behavior (reactive and proactive aggression) and children's classroom peer status. The reciprocity of each of these subtypes of aggressive behavior and the social contexts in which these behaviors occur were also examined. Assessments of each of these forms of aggression among 70 boys (ages 5 and 6) were conducted using direct observations and teacher ratings. In general, directing reactive aggressive behavior toward peers was associated with social rejection, while utilization of instrumental aggression was positively related to peer status. The findings also indicated that directing proactive forms of aggression toward peers was related to being the target of proactive aggression. Finally, among older boys, both subtypes of aggression were more likely to occur during rough play than during any other type of play activity.     

Factors affecting the birth and death of mutual-help groups: The role of national affiliation,professional involvement,and member focal problem

Examined the predictive relationship of three variables to the birth and death of mutual-help groups for a statewide New Jersey sample of 3,152 groups over a 2-year period. The three variables studied were group affiliation with a national mutual-help organization, local professional involvement in group activities, and group members' type of focal problem. Log-linear logit analysis revealed that the best-fitting model included Affiliation Status x Professional Involvement, and Affiliation Status x Focal Problem interactions. Among unaffiliated groups, professional involvement was related to lower group mortality, while among affiliated groups it was related to higher group mortality. Unaffiliated behavior control groups had higher odds for mortality and for birth than either unaffiliated life stress groups or unaffiliated medical groups. Among main effect findings, unaffiliated groups had consistently higher odds for birth than affiliated groups. The implications for research and action are discussed.
