The study explored the role of second-screen use and binge-watching in moderating entertainment education (EE) effects. A pretest/posttest experiment of 273 viewers of East Los High measured the effects of exposure to three subplots, concerning alcohol abuse, abortion, and immigration. The effect of identification with characters on change in attitudes was significantly moderated by second-screen use and binge-watching. In particular, second-screening tended to enhance the positive impact of identification; whereas, among respondents who binge-watched the show, the effects of identification were weaker. 相似文献

The effects of identical context on pattern recognition by pigeons for outline drawings of faces were investigated by training
pigeons to identify (Experiment 1) and categorize (Experiment 2) these stimuli according to the orientation of the mouth—an
upright U shape representing a smiling mouth or an inverted U shape representing a sad mouth. These target stimuli were presented
alone (Pair 1), with three dots in a triangular orientation to represent a nose and eyes (Pair 2), and with the face pattern
surrounded by an oval (Pair 3). In Experiment 1, the pigeons trained with Pair 1 were most accurate, those trained with Pair
2 were less so, and those trained with Pair 3 failed to acquire the discrimination within eighty 100-trial sessions. The same
ordering was found in Experiment 2 for pigeons trained on the three pairs simultaneously. The authors suggest that a contrasting
finding in humans, the face superiority effect, might be due to a gain in discriminability resulting from recognition of the
pattern as a face. An exemplar model of information processing that excludes linguistic coding accounts for the present results. 相似文献

The goals of this research were to explore the current literature regarding associations between psychological stress and adverse fetal outcome, associations between aerobic exercise and psychological stress reduction, and associations between aerobic exercise and fetal outcome. The published studies that were located provide evidence of the following: 1) Stress reactivity increases physiologically during pregnancy, 2) pregnant women may experience additional stressors that are usually not experienced in a nonpregnant state, 3) psychological stress in pregnancy is associated with adverse fetal outcome, 4) exercise can be a method of stress reduction, 5) exercise in pregnancy is not associated with adverse fetal outcome, and 6) exercise in pregnancy may provide benefit to the fetus. Data were analyzed from an original study and associations were reported between psychological stress-management activities and participation in aquatic aerobic exercise classes. No reports were available investigating an exercise-induced reduction in psychological stress with fetal outcome. 相似文献

OBJECTIVES: To investigate whether an information literacy programme for pre-registration nursing students at a UK higher education institution is effective in developing their skills and confidence: examines students' skill levels, factors affecting their confidence, and relationships between skills, confidence and demographic characteristics. METHODS: Quantitative and qualitative techniques were used: pre- and post-tests to measure changes in students' skills and self-assessed confidence levels after two key sessions in their first semester (n = 29); semi-structured interviews to explore factors affecting confidence (n = 5). RESULTS: Findings demonstrated positive impacts on skills and confidence. Key areas of skill development included: identifying journal articles, selecting search terms and evaluating website quality. Factors affecting confidence included: successful 'mastery' experiences in searching for information and the programme itself, especially small-group sessions, handouts and staff support. Evidence on links between skills, confidence and demographic factors was inconclusive. CONCLUSIONS: The study demonstrated the programme's effectiveness and identified areas for development, including the need to help students understand the relative merits of search engines and other sources. Evidence has contributed to a change in departmental policy, making attendance at sessions mandatory. Further studies have been recommended. 相似文献

This study examined the strength of tracking sport participation from childhood to early adulthood among the Dunedin Multidisciplinary Health and Development Study cohort. Participation in sport, dance, or gymnastics as part of a club or group (outside of school) was assessed at ages 7, 9, 15, 18, and 21 years. In addition to the traditionally used correlation coefficients, summary statistics (intraclass correlations; ICC) from random effect models and stability coefficients from generalized estimating equations (GEE) were calculated using all the longitudinal data and controlling for the influence of covariates on tracking strength. Correlation coefficients revealed statistically significant tracking of club sport participation (7-21 years) at low levels (r = .07-0.28). The ICC summary statistic (0.23) was consistent with this, while the GEE suggested moderate tracking (0.59). The results of this study suggest that encouraging sport participation during childhood and adolescence may result in a modest increase in the likelihood of participation later in life. However, the substantial movement into and out of sport participation observed here and in other studies cautions against relying solely on sport promotion among youth as a strategy to promote lifelong participation. 相似文献

Managerialism and equalities: tensions within widening access policy and practice for disabled students in UK universities 总被引:1,自引:0,他引:1

This paper draws on a four-year longitudinal ESRC funded project examining learning experiences of disabled students in higher
education in four universities. The focus here is on institutional responses to the demands of audit culture and legislation
in relation to making reasonable adjustments for students with impairments. The data comes from institutional documents and
face-to-face interviews with key informants within the institutions. The findings indicate that quality assurance regimes
and legislation have had some positive effect on improving access for disabled students; however, local factors and type of
institution also have a major impact on the way that national policies are expressed in particular contexts. 相似文献

Prognostic factors influence the modality and course of therapy in breast cancer. These include both histopathological and
biochemical variables. This study was aimed to find out if any correlation exists between the biochemical tumor marker-serum
CA 15.3, and the lymph node staging of Nottingham’s Prognostic Index (NPI). It was observed that serum CA 15.3 showed a statistically
significant correlation with lymph node staging of NPI. Therefore it is concluded that CA 15.3 can be utilized as a useful
prognostic marker, particularly in cases where histopathological variables such as tumor size and grade have been altered
by pre-operative chemotherapy. 相似文献

Associations Among Infant Iron Deficiency,Childhood Emotion and Attention Regulation,and Adolescent Problem Behaviors 下载免费PDF全文

This study examined whether iron deficiency (ID) in infancy contributes to problem behaviors in adolescence through its influence on poor regulatory abilities in childhood. Chilean infants (N = 1,116) were studied when there was no national program for iron fortification (1991–1996), resulting in high rates of ID (28%) and iron‐deficiency anemia (IDA, 17%). Infants (54% male) were studied at childhood (Mage = 10 years) and adolescence (Mage = 14 years). IDA in infancy was related to excessive alcohol use and risky sexual behavior in adolescence through its effect on poor emotion regulation in childhood. Attentional control deficits at age 10 were also related to both infant IDA and heightened risk taking in adolescence. Findings elucidate how poor childhood regulatory abilities associated with infant IDA compromise adjustment in adolescence. 相似文献
