A microcomputer system for temperature biotelemetry

A microcomputer (Apple II) system for recording body temperature measured by a commercially made, implantable biotelemetry device (Mini-Mitter) is described. The system includes an inexpensive radio receiver interface circuit and software written in BASIC and 6502 assembly language. The utility of the system is illustrated in a study that shows that various handling procedures (including that normally involved in rectal temperature measurement) elevate body temperature in rats.

Depressive thoughts limit working memory capacity in dysphoria

Dysphoria is associated with persistence of attention on mood-congruent information. Longer time attending to mood-congruent information for dysphoric individuals (DIs) detracts from goal-relevant information processing and should reduce working memory (WM) capacity. Study 1 showed that DIs and non-DIs have similar WM capacities. Study 2 embedded depressive information into a WM task. Compared to non-DIs, DIs showed significantly reduced WM capacity for goal-relevant information in this task. Study 3 replicated results from Studies 1 and 2, and further showed that DIs had a significantly greater association between processing speed and recall on the depressively modified WM task compared to non-DIs. The presence of inter-task depressive information leads to DI-related decreased WM capacity. Results suggest dysphoria-related WM capacity deficits when depressive thoughts are present. WM capacity deficits in the presence of depressive thoughts are a plausible mechanism to explain day-to-day memory and concentration difficulties associated with depressed mood.     

What are the combined effects of negative emotions and illness cognitions on self-care in people with type 2 diabetes? A longitudinal structural equation model

Objective: To explore whether negative emotions mediate the effect of diabetes cognitions on diabetes self-care and conversely whether diabetes cognitions mediate the effect of negative emotions on diabetes self-care.

Design: Longitudinal observational study in adults with type 2 diabetes.

Main outcome measures: Self-reported depression and anxiety (Diabetes Wellbeing Questionnaire), cognitions (Illness Perceptions Questionnaire-Revised; Beliefs about Medicines Questionnaire), and diabetes self-care (Summary of Diabetes Self-Care Activities Scale) were completed at baseline and six months. Analyses used structural equation modelling.

Results: Baseline medication concerns were associated with elevated symptoms of depression and anxiety at follow-up, but emotions did not mediate medication concern’s effect on diabetes self-care. Baseline depression and anxiety symptoms were associated with specific diabetes cognitions over time, but these cognition domains did not mediate emotion’s effect on diabetes self-care. Personal control remained independent of emotions and was associated with diabetes self-care over time.

Conclusions: Negative emotions did not act directly or alongside cognitions to influence diabetes self-care. The reciprocal relationship between diabetes cognitions and emotions suggests cognitive restructuring, in addition to other mood management intervention techniques would likely improve the emotional wellbeing of adults with type 2 diabetes. Likewise, personal control beliefs are likely important intervention targets for improving self-care.     

Determinants of Perceived Stress in Adolescence: The Role of Personality Traits,Emotional Abilities,Trait Emotional Intelligence,Self-Efficacy,and Self-Esteem

The aim of the current study was to examine the explanatory power of personality traits, emotional abilities, trait emotional intelligence, self-efficacy, and self-esteem in predicting perceived stress in adolescents. The data were collected from 406 high school students, aged 18-22 years (M_age = 18.47, SD = 0.64). Perceived stress was assessed with the 10-item Perceived Stress Scale (PSS-10). Personality traits were measured with the Eysenck Personality Short Scale (EPQ-R-S), emotional abilities were assessed with two performance tests, the Emotional Intelligence Scale – Faces (SIE-T), and the Emotion Understanding Test (TRE), and trait emotional intelligence was measured with a selfreport questionnaire (the Schutte Emotional Intelligence Scale, SEIS). The Generalized Self-Efficacy Scale (GSES) and the Rosenberg Self-Esteem Scale (RSES) were also used. Results indicate that the strongest determinant of perceived stress in adolescents was high neuroticism. Perceived stress was also determined by low self-efficacy and self-esteem, as well as high extraversion and psychoticism. Women reported higher perceived stress than men. There also were differences in the determinants of perceived stress between graduate and nongraduate students. The obtained results suggest that the development of high self-esteem and high self-efficacy may contribute to perceptions of lower stress in adolescents and may be especially valuable for neurotic individuals and for women, who are more exposed to stress.     

Experimental evidence for aggressive antipredator behavior in black skimmers (rynchops niger)

We experimentally studied the aggressive antipredator behavior of black skimmers Rynchops niger nesting in a salt marsh and sandy beach with the use of a live herring gull Larus argentatus. Although there were no significant habitat differences in vegetation cover, distance from the edge of the colony, or nesting density, skimmers nesting in salt marshes were more aggressive toward the herring gull than were those nesting on the beach. Aggression increased during the first three minutes of the test, and decreased slightly thereafter. Aggression levels were highest when the gull moved compared to when it was stationary. Skimmers made few responses when a person was present with the gull, but aggression increased dramatically when only the gull remained. Our results suggest skimmers may engage in more aggressive behavior in defense of their nests than previously thought, particularly when exposed to a predator that actually takes eggs and chicks. Further, we suggest that conclusions about antipredator behavior drawn only from studies of interactions with people may need further amplification. © 1992 Wiley-Liss, Inc.     

Persistent versus Periodic Experiences of Social Victimization: Predictors of Adjustment

This study examined self-reports of social victimization and parent reports of adjustment for a sample followed from fourth through seventh grades. Different patterns of social victimization experiences were identified; of the 153 students (79 girls) with complete data, 24% reported chronic social victimization, 23% reported transient experiences of social victimization, and 53% reported being socially victimized at no more than one time point. We examined whether students who experienced persistent and periodic social victimization were at greater risk for internalizing problems than nonvictims. Persistently victimized children demonstrated continuously elevated levels of internalizing problems. Children who were not originally victimized by social aggression but became victimized with time did not demonstrate higher levels of internalizing problems than did nonvictims. Findings were mixed for those who escaped social victimization during this period. This research was supported by NIMH grants R01 MH63076 and K02 MH073616. We are deeply grateful for the participation of children and families in this study and for the cooperation of a local school system that wishes to go unnamed. We thank Mikal Galperin for her help with recruiting and retaining the sample.     

How do women experience myocardial infarction? A qualitative exploration of illness perceptions, adjustment and coping

While UK Department of Health policy recognizes the importance of secondary prevention and rehabilitation following a cardiac event, there still appears a dearth of research addressing women's needs. This study aimed to explore adjustment in terms of women's perception of their cardiac event, impact on relationships and coping strategies employed. Five women suffering first time MI were interviewed, using a semi-structured format and were telephoned 2 months later. Data were analysed using Interpretative Phenomenological Analysis. Perceptions included: Making Sense of the Event, Cognitive and Emotional Responses and Self-beliefs. Relationships issues were: Others' Reactions and Change in Relationships and Roles. Cognitive and Behavioural strategies and Support from others (including cardiac rehabilitation) formed coping strategies. For most participants, the event was unexpected evoking uncertainty and later, emotions extending beyond the more widely accepted depression and anxiety. Women tended to minimize severity of symptoms and impact of event (perhaps as a way of coping and protecting others), displaying a strong sense of optimism and hope that life would soon return to "normal". However, it appeared this was difficult to maintain and the experience seemed to challenge relationships and roles. The findings suggest recommendations for further research with possible implications for clinical practice.     

Vaginal Aesthetics

Based on the premise that ugliness looms large in both cultural and women's consciousness of vaginas, I create a representation of the vagina's beauty as rich and sweet. Smell, taste, and touch play predominant roles as I use scholarly analysis and my own autobiographical narratives and poems and poetic language in order to redress the vagina's culturally inherited ugliness.
