It was found that the men's and women's attitudes toward affirmative action (AA) in general were related to differences in self-interest. In addition, consistent with predictions drawn from notions of organizational justice and attribution principles, it was found that people held different attitudes toward different methods of affirmative action. People were most favorable toward AA involving special training programs and least favorable toward AA that employed differential selection criteria for target group members. Attitudes toward quota-based systems were intermediate. 相似文献

Cardiovascular disease is associated with increased risk for cognitive decline and dementia, but it is unclear whether this risk varies across disease states or occurs in the absence of symptomatic stroke. To examine the evidence of increased risk for cognitive decline and dementia following non-stroke cardiovascular disease we conducted two independent meta-analyses in accordance with PRISMA guidelines. The first review examined cardiovascular diagnoses (atrial fibrillation, congestive heart failure, periphery artery disease and myocardial infarction) while the second review assessed the impact of atherosclerotic burden (as indicated by degree of stenosis, calcification score, plaque morphology or number of plaques). Studies eligible for review longitudinally assessed risk for clinically significant cognitive decline and/or dementia and excluded stroke and cognitive impairment at baseline. Summary statistics were computed via the inverse variance weighted method, utilising Cox Proportional Hazards data (Hazard Ratios, HR). Both atrial fibrillation (n = 5, HR = 1.26, 95% CI [1.12, 1.43]) and severe atherosclerosis (n = 4, HR = 1.59, 95% CI [1.12, 2.26]) emerged as significant risk factors for cognitive decline and/or dementia. A small set of studies reviewed, insufficient for meta-analysis, examining congestive heart failure, peripheral artery disease and myocardial infarction suggested that these conditions may also be associated with an increased risk of cognitive decline/dementia. In the absence of stroke, patients with atrial fibrillation or generalised atherosclerosis are at heightened risk for cognitive deterioration. Nonetheless, this paper highlights the need for methodologically rigorous and prospective investigation of the relationship between CVD and dementia. 相似文献

Kirk Summers 《Reformation & Renaissance Review》2018,20(2):134-154
Scholarly discussions on what constitutes Christian humanism in the Renaissance and Reformation periods have typically concentrated on its manifestations before 1536, when Erasmus died. In this period, the old arguments for the reading of the Classics once set out by Basil and Augustine still predominated. Calvin’s teaching on the Fall and the noetic effects of sin, however, provided another basis for the incorporation of pagan thought into Christian learning. Christians who followed Calvin benefited from his precise and comprehensive theological position on the place of worldly knowledge in God’s original creation as a means for justifying their study of the Classics. 相似文献

To determine if listeners can accurately distinguish between real and human-imitated animal sounds, a total of 165 recorded sounds (55 real and 110 human-imitated) of cats, cows, dogs, pigs, and sheep were randomly arranged on a master tape and presented to 30 listeners for discriminative judgments. Results indicate that, in general, listeners can accurately discriminate real from human-imitated animal sounds. Suggestions for future research are discussed. 相似文献

Rhythm and the timing of movement sequences 总被引:1,自引:0,他引:1
Summary Many motor skills involve a sequence of movements phased over a period of time. The present study investigated the importance of rhythmic timing structures in the acquisition and control of a serial key-pressing task. Four groups of subjects received extensive practice on 9-element finger sequences varying in the form of the inherent temporal structure. Following a training period, the stability of the various timing patterns was examined by requiring subjects to perform the key-pressing task concurrently with a verbal memory task. The memory task involved reporting back a sequence of visually-presented words with a lag of one word. A comparison was made of performance on the two tasks under dual task and control (single task) conditions. The results suggested that natural rhythmic timing structures require less attention for production than unnatural temporal patterns. A breakdown of the temporal patterns into within-group and between-group intervals showed that patterns containing within-group intervals that related as 1:1 or 1:2 evidenced good stability under dual-task conditions. These results were taken as support for the suggestion by Fraisse (1946) that the perception and production of rhythms can be understood by an internal representation that allows only two distinct durations that relate as 1:2. Furthermore, it was suggested that relative timing may become an invariant property of motor program representation only in those instances in which the timing sequence completely fits the internal timing structure. 相似文献

The influence of a history of romance on judgments and responses to a complaint of sexual harassment
Results indicated that a female complainant was seen as less innocent and an accused male less guilty when they had previously been romantically involved. As a consequence, decision makers felt it was more appropriate to be lenient in responding to the accused. Also, as demonstrated in previous research, male and female decision makers differed in their judgments and responses to a complaint of sexual harassment. These results have implications for organizational policies concerning workplace romance and for training people to deal with complaints of sexual harassment.Partial support for this study was provided by a Saint Mary's Senate research grant. The authors thank an anonymous reviewer for the helpful comments on an earlier version of the paper. 相似文献

Sixteen right-handed participants without formal musical training performed a rhythmic multifrequency coordination task for
several hours over a one-week period. Two groups were studied with respect to the assignment of hand to frequency: 1L:2R,
in which the preferred right hand performed the higher frequency, and 2L:1R in which the non-preferred left hand performed
the higher frequency. Performance asymmetries in terms of relative phase stability were initially expected and confirmed.
The 1L:2R pattern was more stable than 2L:1R. It has been suggested that performance asymmetries result from asymmetrical
coupling between the limbs as influenced by handedness. This study examined whether the acquisition of 2L:1R, the less stable
of the two patterns, required the formation of asymmetrical coupling such that the faster hand would exert a greater forcing
on the slower hand than vice versa, a supposition put forth in many studies of bimanual polyrhythmic tapping. The present
data provide quantitative evidence that, in terms of stability (as quantified by relative phase uniformity, transition pathways,
and lead-lag relations), handedness asymmetries, as well as acquired asymmetries, can be captured by low-dimensional dynamics
consisting of symmetric and asymmetric coupling terms.

The delayed-matching-to-sample procedure was modified to study pigeons' spatial memory. Nine pecking keys, arranged as a three-by-three matrix, served as the spatial cues. Trials began with a brief "ready" stimulus (dimming of the houselight). Then a randomly chosen key was lit briefly as a sample. After a short delay the sample key was lit again along with one of the other eight keys. A peck at the key that had served as the sample produced grain reinforcement, where as a peck to the other key produced only the intertrial interval. After delayed matching of key location was learned, the effects of sample and delay duration, number of keys illuminated as sample and comparisons, and organization of three-key samples were studied. Matching accuracy decreased as sample duration decreased, delay increased, the number of locations serving as samples increased, the number and proximity of comparisons increased, and when the three-key samples were "discontinuous" rather than "lines". 相似文献

This study compared extra-stimulus to within-stimulus prompts in teaching children with developmental disabilities to discriminate the prepositional concepts In and On. Five preschool-aged children who had difficulty discriminating verbal instructions participated. Extra-stimulus prompts involved modeling, gestures, positioning, and auditory cues which did not form part of the target discrimination. Within-stimulus prompts manipulated the volume and intonational pattern of the verbal stimuli. Four children did not learn the discrimination with extra-stimulus prompting. All four of these children, plus a fifth child who did not have prior experience with extra-stimulus prompting, reached criterion in the within-stimulus prompting condition. The success of the within-stimulus prompts may be related to their enhancing phonetic differences between the verbal stimuli. 相似文献
