The U.S. Supreme Court’s 1991 decision in the Feist case wiped away the idea that “sweat of the brow” is adequate for a copyright
claim. The history of the relevant issues is discussed and the Court’s decision is examined. The decision has a number of
implications for publishers but leaves many questions unanswered. 相似文献

The effects of cooperative and individualistic learning experiences were compared on (1) interpersonal attraction between nonhandicapped fifth- and sixth-grade elementary school students and learning-disabled peers and (2) achievement. Students participated in a language arts class lasting 90 min a day for 17 days. The results indicate that greater interpersonal attraction between the learning-disabled and normal-progress students and higher achievement resulted in the cooperative than in the competitive condition. 相似文献

Expert performers in striking sports can hit objects moving at high speed with incredible precision. Exceptionally well developed anticipation skills are necessary to cope with the severe constraints on interception. In this papr we provide a review of the empirical evidence regarding expert interception in striking sports and propose a preliminary model of expert anticipation. Central to the review and the model is the notion that the visual information used to guide the sequential phases of the striking action is systematically different between experts and nonexperts. Knowing the factors that contribute to expert anticipation, and how anticipation may guide skilled performance in striking sports, has practical implications for assessment and training across skill levels. 相似文献

The purpose of this study is to provide evidence of technique changes during learning a sports-specific skill, the looped bar longswing (LLS). Thirteen male participants with no previous high bar experience took part in a training study. Kinematic data were collected using a CODA motion analysis system (200 Hz) during eight weekly testing sessions. Analyses focused on the amplitude of swing and the functional phase (FP) actions, defined by the rapid flexion to extension of the shoulders and extension to flexion of the hips as the performer passed through the lower vertical. Three groups were identified based on the number of sessions it took each participant to perform the LLS (G1: most successful, G2: intermediate, and G3: least successful). All participants were able to significantly increase swing amplitude over the training period (p < 0.05). For each participant the hip FP started significantly: later for G1, earlier for G2, and did not change for G3. Extension actions at the shoulders were dissimilar to those reported for elite gymnasts performing the longswing. The FP of the hips provides a mechanism to distinguish between the learners of different skill levels. The study has provided support for a single-subject design when investigating technique changes during learning. 相似文献

OBJECTIVE: To evaluate the psychometric properties of a new measure, the Abuse-Related Beliefs Questionnaire (ARBQ), designed to assess abuse-related beliefs among adult survivors of childhood sexual abuse (CSA). Study 1 examined the structure of the scale, and Study 2 evaluated its reliability and validity. METHOD: One hundred and seventy female CSA survivors recruited into a group psychotherapy intervention study were administered the ARBQ in Study 1. A subsample of 45 women completed the ARBQ again 12 months later. In Study 2, 70 women from a health maintenance organization who identified themselves as survivors of CSA completed the ARBQ along with the Trauma Symptom Checklist-40 (TSC-40) and the Symptom Checklist 90R (SCL-90-R). RESULTS: Three reliable ARBQ subscales emerged in Study 1: Guilt, Shame, and Resilience. Twelve-month test-retest reliability was high (r=.60-.64). The internal consistency of the subscales was further supported in Study 2, and validity was demonstrated by moderate to high correlations with the distress measures. CONCLUSIONS: The results indicate that the ARBQ has good psychometric characteristics, supporting the feasibility of its use in measuring abuse-related beliefs in research on survivors of CSA. A next step for validation of the ARBQ would be to evaluate its sensitivity in measuring changes in studies of interventions for treating CSA survivors. 相似文献
