This study aimed at determining the amount of Italian television coverage dedicated to men's and women's sport and the number of male and female viewers during the 2004 Summer Olympic Games. AUDITEL-AGB Nielsen Media Research Italia provided the TV airtime data for the sport events broadcast, which were classified into three categories: men-only, women-only, and mixed-gender. The viewer sample was divided by age and gender and included three audience parameters: mean audience, share, and appreciation index. The last item is calculated from the program duration, audience permanence, and the share related to programs broadcast by other Italian channels. In particular, the appreciation index was used to investigate the relationship between (a) the viewer's and sport participants' gender and (b) the effect of Italian participation and expectations for sport achievement. The data showed that Italian male athletes outnumbered their female counterparts. Women's sport was allotted significantly less airtime than men's sport, but this imbalance was not proportional to the gender difference in the overall athletes' participation in the Games. Although the female audience represented 45% of the total, a significantly higher male mean audience and share were found. On the other hand, the appreciation of men's and women's sport events was balanced after equating for differences in media coverage. Moreover, sport achievement might have a positive effect on the trend toward equality of gender coverage, indicating that a global multisport event such as the Olympic Games is central to communicating a national image and identity independently of the athletes' gender. 相似文献

基于事件分析法的国家创新政策对高新技术产业的影响分析 总被引：1，自引：0，他引：1
选取在深圳中小板上市的高新技术企业为样本,运用事件分析法分析了我国2006年以来创新政策中的税收优惠政策的颁布对公司市场价值的影响。与考察单个事件影响原理不同,此次研究的税收优惠政策为＂间断发生的同类事件＂,故通过对该类事件发生作用的事件窗口内的＂异常波动＂来衡量事件的影响作用。实证研究结果表明：税收优惠政策的颁布给深圳中小板上市的高新技术企业市场价值带来了正向影响。此外,以传统的石化产业和新兴的生物医药产业为例,研究创新政策对不同产业公司的影响差异。结果表明：税收优惠政策的颁布对不同产业的平均超常收益率和累积平均超常收益率影响趋势基本相同,均呈现出增长趋势;但相比而言,对新兴的高新技术产业影响更为显著。 相似文献

Comparison of three generations of ActiGraph™ activity monitors in children and adolescents 总被引：3，自引：3，他引：0
Abstract In this study, we evaluated agreement among three generations of ActiGraph? accelerometers in children and adolescents. Twenty-nine participants (mean age?=?14.2?±?3.0 years) completed two laboratory-based activity sessions, each lasting 60?min. During each session, participants concurrently wore three different models of the ActiGraph? accelerometers (GT1M, GT3X, GT3X+). Agreement among the three models for vertical axis counts, vector magnitude counts, and time spent in moderate-to-vigorous physical exercise (MVPA) was evaluated by calculating intraclass correlation coefficients and Bland-Altman plots. The intraclass correlation coefficient for total vertical axis counts, total vector magnitude counts, and estimated MVPA was 0.994 (95% CI?=?0.989-0.996), 0.981 (95% CI?=?0.969-0.989), and 0.996 (95% CI?=?0.989-0.998), respectively. Inter-monitor differences for total vertical axis and vector magnitude counts ranged from 0.3% to 1.5%, while inter-monitor differences for estimated MVPA were equal to or close to zero. On the basis of these findings, we conclude that there is strong agreement between the GT1M, GT3X, and GT3X+ activity monitors, thus making it acceptable for researchers and practitioners to use different ActiGraph? models within a given study. 相似文献

It has been reported that academic dishonesty is a prevalent problem that crosses all disciplines at the university level. But, how prevalent is it in Sweden? Little is published in the literature about lying, cheating, and plagiarism amongst Swedish university students. This paper focuses on the frequency of past specific academically dishonest behaviours amongst Swedish University students with consideration to social desirability. The results indicate that although there are variations in frequency of dishonest behaviours amongst university students, some dishonest behaviours are more common than others. Future perspectives are discussed. 相似文献

The within-compound association approach has been proposed as an account of synergistic conditioning in flavor aversion learning.
One prediction from the within-compound association approach is that following taste + odor compound conditioning, postconditioning
inflation of one element of the compound should increase responding to the second element. In four experiments with rats,
the AX+/A+ design was used to determine whether postconditioning inflation of A would increase responding to X. In Experiments
1 and 3, responding to X was significantly stronger after AX+/A+ conditioning, as compared with AX+ conditioning. In Experiments
2 and 4, the specificity of the inflation effect was demonstrated, because AX+/A+ conditioning produced a stronger aversion
to X than did AX+/B+ conditioning. Furthermore, it appears that the taste + odor association is symmetrical because inflation
of the taste aversion increased responding to the odor (Experiments 1 and 2) and inflation of the odor aversion increased
responding to the taste (Experiments 3 and 4). 相似文献

This study examined the records of the North Carolina Central Registry of Child Abuse and Neglect to determine which social, family, and child characteristics were most influential in the decision to place a child in foster care. These records contained all theoretically relevant factors as well as demographic data. Analysis included the computation of odds ratios for foster care for each of 250 variables. A maximum likelihood logistic regression model was constructed to obtain the independent and cumulative contribution of each factor. Some expected variables such as parental stress factors (substance abuse) and types of abuse (burns and scalds) placed a child at a significant risk for placement in foster care (p < 0.01). However, less obvious factors such as referral source (law enforcement agencies) or geographic area also placed children at risk. Overall, the model explained little of the variance of these decisions (R2 = 0.168) and poorly predicted placement (sensitivity 66.3 per cent, specificity 74.6 per cent). Using existing data. we were unable to adequately describe the decision process in selecting foster care. 相似文献
