Voting and Values: Reciprocal Effects over Time

Two studies investigated reciprocal effects of values and voting. Study 1 measured adults' basic values and core political values both before (n = 1379) and following (n = 1030) the 2006 Italian national election. Both types of values predicted voting. Voting choice influenced subsequent core political values but not basic values. The political values of free enterprise, civil liberties, equality, law and order, military intervention, and accepting immigrants changed to become more compatible with the ideology of the chosen coalition. Study 2 measured core political values before (n = 697) and following (n = 506) the 2008 Italian national election. It largely replicated the reciprocal effects of voting and political values of Study 1. In addition, it demonstrated that left‐right ideology mediated the reciprocal effects of voting and political values. Moreover, voter certainty moderated these effects. Political values predicted vote choice more weakly among undecided than decided voters, but voting choice led to more value change among undecided voters.     

Quality adjusted survival analysis: A neglected application of the quality of well-being scale

Abstract

Background In survival analysis, those who are alive are statistically coded as 1.0 while those who are dead are coded as 0.0. Since everyone who remains alive is given the same score, a person confined to bed with an irreversible coma is alive and is counted the same as someone who is active and asymtomatic. The Quality of Well-being (QWB) scale defines levels of wellness on the continuum between death and optimum function and integrates morbidity and mortality into the same number. This paper demonstrates the effect of including mortality in QWB estimates for male adults with HIV infection.

Method This study involves follow-up of a cohort of 386 male adults participating in the San Diego HIV Neurobehavioral Research Center (HNRC). Patients were evaluated using the QWB at enrollment and at six month intervals. All patients were classified into three stages of HIV disease according to the Center for Disease Control (CDC) classification: CDC IV (symptomatic HIV disease), CDC II or III (asymptomatic infection) and uninfected male controls.

Results QWB scores were calculated with and without mortality included for men in each CDC class who completed a one year (N = 148) or two year follow-up (N = 60). At each evaluation, there were significant differences among CDC classes and inclusion of deaths increased the variance accounted for by CDC class at each evaluation.

Conclusions HIV infection has significant impacts upon both morbidity and mortality. Survival analysis captures only the mortality dimension, while quality adjusted survival analysis using the QWB includes both dimensions. We propose quality adjusted survival analysis as a more sensitive method for assessing outcome in HIV disease and other health conditions.     

The effects of stressor predictability on lymphocyte proliferation in humans

Abstract

To demonstrate the effects of predictable and unpredictable stressors on immune function, 36 male subjects were randomly assigned to complete ten trials of either a predictable or unpredictable cold pressor task or a non-stressful warm pressor control task. The predictable and no-stressor groups were given information about the duration of each pressor trial and a countdown of seconds passed from beginning to end of each trial. The unpredictable stressor group received no information. Self-report, cardiovascular, and biochemical measures were taken throughout the tasks in order to ascertain the effectiveness of the predictability and stressor manipulations. Lymphocyte proliferation to concanavalin A (Con A) and pokeweed mitogen (PWM) were measured before, during and after the tasks. Lymphocyte proliferation to Con A (10/μg/ml) was significantly reduced only in response to the unpredictable stressor suggesting that predictability buffered the effect of the stressor on immune function. Proliferation to PWM followed a similar pattern but was not statistically significant. Blood pressure responses were negatively correlated with proliferation values suggesting that stressor predictability may attenuate stress-associated immune decreases by reducing sympathetic arousal.     

Quality-of-life after penile prosthesis placed at radical prostatectomy

Abstract

The clinical and psychosocial effects of immediate penile prosthesis implantation at the time of radical prostatectomy (RP) were investigated in 97 consecutive patients and 68 partners. Prosthesis recipients reported more frequent sexual contact, fewer marital problems and slightly fewer sexual functioning problems than the RP-alone patients. There were no group differences on any sociodemographic characteristics, on disease recurrence, on physical and psychosocial functioning, or on reported depression. Patients who chose the prosthesis did, however, evidence less of a link between depression and functional limitations and between depression and marital problems. They also had lower levels of agreement with their partners in reporting their own depression, as compared to the patients who opted for RP surgery alone. We conclude that the penile prosthesis was associated with an increased frequency of sexual contact, a reduction in reported marital problems, and stylistic differences between the two patient groups in dealing with affect.     

The Essence of Essence

Despite its appeal and popularity, the view that membership in a natural kind is essential to an individual is unsupported by the logic of essences and has no compelling reflective support. While the view has strong intuitive and empirical support this is insufficient to establish it. There are advantages to abandoning the view that kind membership is essential to individuals. One of these advantages is that it allows for a reconfiguring of the problem of material constitution in a way that removes much of the paradox.     

Constructing and measuring self-esteem

Abstract

The concept of self-esteem is examined as it relates to the theory and practice of personal construct psychology (PCP). William James's two perspectives on the self, as a knower and as an object of knowledge, are related to two PCP perspectives, the self as a construct and the self as an element. Various PCP concepts, such as core role constructs, range of convenience, and emergent poles, are interpreted in regard to self-esteem. Methods for changing self-constructions to enhance self-esteem are also described. A modified repertory grid format is recommended for the study of self-esteem, one that uses positive experiences as grid elements instead of people who fit selected roles.     

Electroencephalographic registration of low concentrations of isoamyl acetate

Previous research has demonstrated electroencephalogram (EEG) changes in response to low-odor concentrations, resulting in near-chance detection. Such findings have been taken as evidence for olfaction without awareness. We replicated and extended previous work by examining EEG responses to water-water control, 0.0001, 0. 001, 0.01, and 1 ppm isoamyl acetate (IAA) in water paired with water only. Detection was above chance (>50%) for.001 and above, and alpha decreased only to those concentrations, suggesting that EEG changes corresponded to IAA awareness. However, when correct trial EEGs were compared to incorrect trial EEGs during.001 ppm, right posterior/central alpha decreased during incorrect trials and alpha decreased more globally (including frontal sites) during correct trials. These data may not reflect awareness or unawareness per se. Instead, results are discussed regarding activation of perceptual systems in the posterior region during incorrect trials and the activation of frontal action systems during a subset of correct trials.
