Survey research has played a major role in American social science. An outgrowth of efforts by the United States Department of Agriculture in the 1930s, the Division of Program Surveys (DPS) played an important role in the development of survey methodology. The DPS was headed by the ambitious and entrepreneurial Rensis Likert, populated by young and talented social scientists getting their first practical experience, and fed by the needs of the US government fighting World War II. The DPS innovations included open-ended interviewing and area probability sampling methodology as illustrated in the War Bond studies and the Master Sample of Agriculture. This paper examines the creation of the DPS, its work, and its legacy. 相似文献

The authors examined the movement patterns of 5 left-handed handball players (ranging from beginner to national level) who threw a handball to different sections of a goal as if a goalkeeper were present. The authors used time-continuous, 3-dimensional kinematic data to assess interindividual movement patterns and considered participants' intraindividual differences relative to different targets. Cluster analysis yielded the highest assignment rates for level of expertise; a mean of 92% of trials was correctly assessed. The authors observed an interaction with expertise for the intraindividual movement patterns. Variability in the novice throwers was increased, whereas (a) advanced throwers experienced a period of stability, and (b) the expert thrower's variability was increased. The results indicate that random variability characterizes novice motor performance, whereas active functional variability may exemplify expert motor performance. 相似文献

As more researchers utilize the Five-factor model (FFM) of personality with children and adolescents, the need for instruments designed specifically for use with children and adolescents increases. In the United States, the 108-item Inventory of Children's Individual Differences (ICID; Halverson et al., 2003), has provided researchers with an age and culture neutral instrument designed specifically to assess the FFM of personality in children and adolescents, ages 2 to 15, using parental, nonparental, or self-reports. This article presents a shorter, 50-item version of the ICID (the ICID-S) that maintains the levels of validity and reliability previously established for the full instrument. 相似文献

We investigated the student-teacher relationships (STRs) of 6-year-old children with (n = 58) and without (n = 82) intellectual disability (ID). We also examined early (age 3) and concurrent (age 6) child behavioral, self-regulatory, and social characteristics as predictors of age 6 STR quality. Children with ID experienced significantly poorer relationships with their teachers, marked by less closeness and more conflict and dependency, compared to typically developing children. This group difference was not accounted for entirely by IQ differences. Child characteristics and parent-child interactional variables at age 3 and 6 accounted for 53.5% of the variance in age 6 STR quality. The relation between ID status and STR quality was fully mediated by three child variables-global self-regulation at age 3, mother-reported behavior problems at age 6, and teacher-reported behavior problems at age 6- and was partially mediated by mother-reported behavior problems at age 3. Our findings demonstrate the importance of child behavioral and social characteristics in predicting relationships with teachers for children with and without ID. 相似文献

PURPOSE: Given the prevalence of physical inactivity among American adults, convenient, low-cost interventions are strongly indicated. This study determined the 6- and 12-month effectiveness of telephone interventions delivered by health educators or by an automated computer system in promoting physical activity. DESIGN: Initially inactive men and women age 55 years and older (N = 218) in stable health participated. Participants were randomly assigned to human advice, automated advice, or health education control. MEASURES: The validated 7-day physical activity recall interview was used to estimate minutes of moderate to vigorous physical activity. Physical activity differences by experimental arm were verified on a random subsample via accelerometry. RESULTS: Using intention-to-treat analysis, at 6 months, participants in both interventions, although not differing from one another, showed significant improvements in weekly physical activity compared with controls. These differences were generally maintained at 12 months, with both intervention arms remaining above the target of 150 min per week of moderate to vigorous physical activity on average. CONCLUSION: Automated telephone-linked delivery systems represent an effective alternative for delivering physical activity advice to inactive older adults. 相似文献

A study was conducted to determine the effects of vocal cues on judgements of dominance in an interpersonal influence context. Physical measures of human vocal cues and participant ratings of dominance were obtained from videotapes of actors delivering short influence messages. After controlling for linguistic and visual content of messages, results indicated that mean amplitude and amplitude standard deviation were positively associated with dominance judgments, whereas speech rate was negatively associated with dominance judgments. An unexpected interaction revealed that mean fundamental frequency (F0) was positively associated with dominance judgments for male speakers but not significantly associated with dominance judgments for female speakers. F0 standard deviation was not significantly associated with dominance judgments. Results support the conclusion that dominance judgments are inferred from multiple sources of information and that some vocal markers of dominance are more influential than others. 相似文献

In this paper the author attempts to show that Lötter is not justified in ignoring orthodox views of personal identity on the basis of arguments offered by Taylor. It is argued that Taylor's arguments against the orthodoxy do not establish what he, and Lötter, hope they establish, namely, that the orthodox position, represented by the work of Parfit, fails to account for personal identity. The author also attempts to show the importance of this area of debate between orthodox theories of personal identity and the concept of personal identity offered by Taylor, Lötter, and others. 相似文献
