In this paper I wish to show that we can give a statement of a restricted form of Gleason's Theorem that is classically equivalent to the standard formulation, but that avoids the counterexample that Hellman gives in Gleason's Theorem is not Constructively Provable. 相似文献

We investigated whether variations in alertness among individuals with profound multiple disabilities affected subsequent responsiveness to training programs. Three experiments were conducted involving 5 people. In Experiment 1, results indicated that alertness of 3 individuals increased with provision of skill-acquisition training programs. Results also indicated no predictive relationship between alertness levels prior to training and subsequent responsiveness to training. Experiment 2 replicated results of Experiment 1 with 2 participants from Experiment 1 and an additional participant. Results of Experiment 2 also indicated that the increased alertness levels accompanying provision of training were not a function of the participants simply being in an inactive environment prior to training. Results of Experiment 3 indicated that alertness of an additional participant increased through provision of another training intervention, involving a systematic preference assessment. Responses during the preference assessment appeared to be unrelated to previously existing alertness levels. These findings suggest the need for caution when considering the withholding of scheduled training because an individual appears to be nonalert. 相似文献

We evaluated a means of increasing staff members' interactions with an individual with multiple disabilities through use of a voice output communication aid (VOCA). When activated, the VOCA allowed the individual to communicate through synthesized speech. Results indicated that staff members interacted with the individual more frequently when she had access to the VOCA, suggesting that VOCAs may represent an alternative to more traditional staff management programs for increasing interactions. 相似文献

Traits like simplicity and explanatory power have traditionally been treated as values internal to the sciences, constitutive rather than contextual. As such they are cognitive virtues. This essay contrasts a traditional set of such virtues with a set of alternative virtues drawn from feminist writings about the sciences. In certain theoretical contexts, the only reasons for preferring a traditional or an alternative virtue are socio-political. This undermines the notion that the traditional virtues can be considered purely cognitive.I am grateful to participants in the Indiana University Workshop on Social Values in the Context of Justification for their comments on an earlier, spoken, version of this paper. 相似文献

This study considers how high school students perceive incidents of possible sexual harassment toward students and how they define sexual harassment. Thirty-five male and 38 female high school seniors (44% Asian-American; 40% white, non-Hispanic; 6% Indian-American; 4% African-American; 3% Hispanic; and 3% other ethnic groups) evaluated scenarios that varied the type of sexual harassment, the status of the initiator (either teacher or student), and the gender composition of the dyad (either male toward female or female toward male). As predicted, type of harassment influenced ratings of severity. Compared to male respondents, female respondents rated the scenarios as more severe. Teachers were judged more critically than students. Differences in status were more apparent at less severe levels of harassment. In defining harassment, students relied on four factors: the behavior itself, the target's reaction to the behavior, the perpetrator's intentions, and the relationship that existed between the two people. Overall, the findings underline the importance of examining high schools as a locale for harassment.This study was originally conducted by the first author as a Westinghouse Science project at Stuyvesant High School, with the guidance of the second and third authors. 相似文献

Previous research indicates that vasopressin-containing (LE) rats are capable of adapting to the stress of food restriction,
whereas vasopressin-deficient (DI) rats cannot adapt to this stressor. It has been postulated that abnormalities in glucose
metabolism may be one of the factors leading to the demise of food-restricted DI rats. The present study was conducted to
determine if taste preferences are altered in DI animals and if the presentation of exogenous glucose, in the form of sucrose
solutions, can ameliorate the effects of the stress of food restriction. Four different concentrations of sucrose solutions
were presented to LE and DI rats under the food-restricted condition. In both strains, an 8% sucrose solution was preferred
over 0%, 16%, and 32% concentrations, with DI rats consuming more of this concentration than LE rats. Thus, when DI rats had
the opportunity of maintaining glucose homeostasis by exogenous supplements, they maintained body weight, displayed no stomach
pathology, and survived. 相似文献

Relatives (N=121) of adult schizophrenia patients were interviewed to investigate predictors of their level of psychological distress and of rejecting attitudes toward the sufferer. The relatives' total stress, particularly that associated with poor communication skills in the sufferer, predicted several measures of their psychological distress, and the same variables plus turbulence of sufferer behavior (i.e., violence and disruptiveness) predicted rejection of the sufferer by the relative. In each case, adequacy of family support moderated the influence of the stressors, although this effect was more marked for distress outcomes than for rejection. The results have important implications for the sorts of professional and peer support which relatives may need to encourage their performance of this potentially burdensome role. In addition, the results fit a classic stress management model and provide a feasible alternative to the Expressed Emotion Model of the relationship between relatives' rejection and patients' illness severity. 相似文献

A contrived play group procedure was utilized to examine the behavioral and social-cognitive correlates of reactive aggression, proactive aggression, and victimization via peers. Eleven play groups, each of which consisted of six familiar African-American 8-year-old boys, met for 45-min sessions on five consecutive days. Social-cognitive interviews were conducted following the second and fourth sessions. Play group interactions were videotaped and examined by trained observers. High rates of proactive aggression were associated with positive outcome expectancies for aggression/assertion, frequent displays of assertive social behavior, and low rates of submissive behavior. Reactive aggression was associated with hostile attributional tendencies and frequent victimization by peers. Victimization was associated with submissive behavior, hostile attributional bias, reactive aggression, and negative outcome expectations for aggression/assertion. These results demonstrate that there is a theoretically coherent and empirically distinct set of correlates associated with each of the examined aggression subtypes, and with victimization by peers. 相似文献

The health belief model was evaluated for its ability to predict perceived and actual dietary quality. The assessment relied upon data collected from 1,502 respondents by the US. Department of Agriculture in its 1991 Continuing Survey of Food Intakes by Individuals and the Diet and Health Knowledge Survey. The health belief model provided good prediction of perceived dietary quality, but provided moderate to weak prediction of 7 measures of actual dietary quality that were calculated from food intake records. Implications are suggested for using the health belief model to understand the determinants of dietary quality. 相似文献
