Economic Exploitation in Intercollegiate Athletics

This paper investigates philosophically the question of whether or not college and university athletes in the USA are doing something morally wrong should they terminate their college or university experience prior to graduation and enter the professional athletic ranks. Various moral arguments are brought to bear in order to attempt to shed light on this issue. One reason why such athletes ‘turn professional’ before they graduate is the perceived economic exploitation they experience as essentially underpaid workers earning much revenue for their respective institutions. But who is exploiting whom here? Is it just student athletes who are exploited by the system? I expand the reasoning about the exploitation of intercollegiate athletics to include not just student athletes, but their supporting colleges and universities. In the end, it is proposed that the National Collegiate Athletic Association and similar academically related athletic agencies should permit and encourage each of their constituent institutions as a matter of policy to protect themselves (and their supporting taxpayers, in the cases of public institutions) contractually from economic exploitation by professional sports franchises. Thus the question of student athletes leaving college for professional sports contracts has hidden beneath it questions of private professional sports franchises’ exploitation of the institutions with which such student athletes are affiliated.     

Transcranial Doppler Ultrasonography Monitoring of Cerebral Hemodynamics During Performance of Cognitive Tasks: A Review

The examination of blood flow velocity (BFV) changes during the performance of mental tasks is one of the applications of transcranial Doppler (TCD) ultrasonography. The purpose of this review is to summarize the results of the functional TCD literature, to investigate the effects of methodological differences between studies, and to provide guidelines for future research. It is concluded that larger series of more homogeneous groups concerning age and handedness, and stricter criteria for subject selection and laboratory setting are required. The implication of quantitative and qualitative performance measures and psychological parameters (motivation, anxiety, and task anticipation) could also yield important information. We recommend future agreement upon a more standardized methodology. TCD promises to be a useful tool to provide further insight into the cerebral organization and temporal reactivity of the human brain.     

Spirituality Predicts Health and Cardiovascular Responses to Stress in Young Adult Women

The primary focus of this study was to investigate the roles of spirituality and religiosity in self-reported physical health, and to determine whether there is an association between an individuals spirituality and cardiovascular responses to two stressors. Fifty-two females participated in both a betrayal interview and a structured interview, during which blood pressure and heart rate were monitored. Spirituality, as assessed by the Spiritual Well-being Scale, was associated with perceived stress, subjective well-being, and medication use. The Existential Well-being subscale predicted fewer physical health symptoms and was associated with lower mean heart rate and decreased heart rate reactivity. The Religious Well-being subscale was associated with reduced systolic blood pressure reactivity in response to the structured interview. These findings suggest that spirituality may have a salutary effect on health, even in a fairly young sample. While previous studies have predominantly reported that religion, as well as spirituality, have a health protective effect, this study did not find strong support for that conclusion. Religiosity in this age group may still be undergoing developmental maturity, which may explain the lack of relationships to health.     

Intertask consistency of blood pressure responses to laboratory stressors may increase with prolonged exposure

In this study, one of the predictions of the reactivity hypothesis was investigated: the intertask consistency of blood pressure (BP) responses. Twelve young male subjects underwent cold-pressor (14°C) and digit-scan (counting even numbers) tests in randomized order. Cardiovascular parameters were recorded during a 2-min pretask baseline, a 10-min stressful exposure, and over a 5-min post-task baseline. The intertask correlations between the cold pressor and digit scan increased with prolonged exposure and were higher for almost all of the systolic BP measurements than for the diastolic measurements. After prolonged exposure, the hemodynamic mechanisms of BP elevations during the digit scan shifted from an increase in both cardiac output and peripheral vascular resistance to solely an increase in peripheral vascular resistance. Increased peripheral vascular resistance was the consistent cause of the BP elevations with the cold pressor. Accordingly, the hemodynamic shift on the part of the digit scan seemed to heighten the intertask BP correlations. Some other factors influencing the intertask BP correlations are also discussed.     

When cooler heads prevail: peacemakers in a sports riot.

Male sports fans (N = 74) were asked to estimate the likelihood that they would intervene in a crowd disturbance in an attempt to stop the fighting. They also completed a battery of measures that included their attitude toward law and order, fight history, the false consensus effect, impulsivity, psychopathy, sensation seeking, anger, physical aggression and identification with their favorite team. Law and order, body mass, anger and the false consensus effect were positively related to peacemaking whereas sensation seeking was negatively related. A multiple regression analysis yielded a solution that accounted for 32.3% of the variance with anger and attitude toward law and order emerging as the best predictors.     

Control and maintenance effects of long-term relaxation training in a case of hypertension

The effects of long-term, varied relaxation in a case of essential hypertension are described. The client's unusual achievement of voluntary control over his blood pressure was discussed in terms of new directions in the search of a relaxation specific factor.     

THE EFFECTS OF FEEDBACK ON BLOOD PRESSURE DISCRIMINATION

Discrimination of blood pressure in the natural environment as a function of feedback was assessed. Seventeen normotensives screened for blood pressure lability were randomly assigned to two groups. These subjects were then asked to estimate their systolic and diastolic blood pressure values two times per day over a 4-week period. Feedback for accuracy of blood pressure discriminations was implemented across the two groups in a multiple baseline fashion, using a feedback withdrawal condition in Group I to assess maintenance effects over time. Results showed improvement in discrimination accuracy for subjects in both groups when feedback was used, and no decrement in performance over a 2-week period after feedback was removed for subjects in Group I. Discrimination of systolic pressures improved at a slightly faster rate than discrimination of diastolic pressures.     

Analogue drinking assessment: Sensation seeking and gender

This study assessed the relationship between sensation seeking measured as a trait variable and drinking behaviors observed unobtrusively in the laboratory. It was hypothesized that high-sensation-seeking subjects would consume more alcohol than low sensation seekers and experience greater enhancement of positive moods and body sensations associated with intoxication. Thirty female and 31 male subjects divided into high- and low-sensation-seeking subgroups participated in an ad libitum drinking situation with the manifest task of taste rating three types of vodka (actually 95% alcohol) or tonic. Dependent variables included beverage consumption, positive/negative mood states, body sensations, breath estimates of blood alcohol levels, and self-rated level of intoxication. All subjects reported feeling the effects of alcohol. Contrary to predictions, high-sensation-seeking subjects neither consumed more alcohol than their low-sensation-seeking counterparts nor drank more alcohol than tonic, Paradoxically, low-sensation-seeking women displayed significantly greater alcohol intake and intoxication than all other groups. Possible explanations for findings were considered as well as the necessity for multimethod assessments of both predictor (i.e., sensation seeking) and criterion (i.e., alcohol consumption) variables across time and situations.This research was supported by Grant Award AA04042-03 from the National Institute on Alcohol Abuse and Alcoholism to the first and third authors.
