Radio listening in the United States fell by more than 10% between 1998 and 2003. During this time, broadcast radio faced new competition from satellite radio and the Internet while the industry was also undergoing significant changes due to increased radio ownership caps. This article quantifies the effects of these factors on audience sizes and explores the implications for audience composition and programming content. The results show that industry consolidation played a larger role in decreasing overall listening than new technology. New technology did have a role in altering the distribution of listeners among programming formats. 相似文献

To determine what maximizes the effectiveness of on‐air promotions, as measured by ratings/share changes, this study tested a seven‐part model focusing on the structural salience of network prime‐time promos carried within other prime‐time programs. The results of analysis of more than 5,000 promos carried within 656 videotaped prime‐time hours provided consistent support for the salience model. Results showed significant changes in industry promotional practices over time and significant differences by network, genre, and the familiarity of the program to audiences. Although lead‐in ratings remained the dominant force impacting ratings for series programs (but not sporting events, movies, or specials), promotional salience variables contributed significantly to improved ratings, especially for mid‐rated continuing programs. 相似文献

This paper compares the No Blame approach to bullying with the ecosystemic approach to changing problem behaviour. It suggests that there are several similarities between the two approaches: they are both applicable in particular kinds of situation; their success depends to a great extent on the people using the technique, in particular the degree to which they can bring the quality of genuineness to the situation; they are not directly concerned with punishment, truth or control; and they challenge the assumptions teachers make about children's problem behaviour. A key point is the need for teachers to recognize that bullying is a natural event (in so far that it is a regular one) and the need to suspend their own feelings of anger and repugnance. As the writer points out, 'a process which fails to engage the bully and makes no attempt to enhance feelings of concern and understanding is unlikely to bring about any fundamental change in behaviour'. Though written at a fairly theoretical level, what the writer says has direct relevance to practice in schools. 相似文献

This study assessed the impact of content--as opposed to structural--factors on television program ratings, seeking to locate clusters of components that would identify effective on-air promotion and allocate content a better-defined place within theoretic models of media priming. Stepwise multiple regression analyses of 1,547 on-air promos for 155 prime-time programs demonstrated that 5-9% of ratings variance was accounted for by content appeals, humor, and presentation in promos for comedy programs. The influence of content variables was greater for familiar than unfamiliar comedies, and humor and presentation in promos contributed to variance in ratings for mid-rated but not high- or low-rated comedies. 相似文献

The transition to motherhood triggers changes in human brain structure that may facilitate mother–infant bonding. Although much research on maternal cortical responses to infant faces has focused on the postpartum period, no previous study has examined whether longitudinal functional changes in the maternal cortex during pregnancy and postpartum are associated with mother–infant bonding. Using electroencephalography, prenatal to postnatal changes in cortical sensitivity (P1, P2, late positive potential, N170 event-related potentials) to infant and adult faces were examined in relation to reported mother–infant bonding in 40 mothers (Mage = 30.5 years). Prenatal to postnatal increases in P1 and P2 responses to infant faces predicted stronger bonding. Findings suggest that cortical changes in attention allocation rather than in face-specific encoding enhance bonding. 相似文献

ABSTRACTA high incidence of overuse knee injuries among youth basketball players may be attributed to number of jumps. Wearable technology may be an effective tool for measuring jump load compared to traditional counting methods. The purpose of this study was to validate a commercially available jump counter (VERT® Classic) in youth basketball practices and games, and to identify the characteristics (i.e., height, direction, takeoff) of jumps recorded by the VERT® Classic. 46 (19F, 27M) youth basketball players wore a VERT® Classic and were recorded on video during games and practices. The number of jumps recorded by the VERT® Classic and evaluated by video raters were compared for each jump characteristic using intraclass correlation coefficient (ICC(3,k)), mean offset, and limits of agreement. The number and percent of VERT® Classic jumps and corresponding video jumps according to timestamp were reported. VERT® Classic jumps had excellent reliability with video-counted jumps over 15 cm (ICC(3,k) = 0.958), with a mean offset of ?2.4 jumps (fewer VERT® Classic) and limits of agreement ?12.6 to 7.8 jumps. Pairs of corresponding jumps represented 68.0% of total video jumps and 92.0% of VERT® Classic jumps. The VERT® Classic can provide an estimate of jump load in youth basketball. 相似文献

Abstract This study shares the results of a citation analysis performed on the publications of the faculty of the College of Business at a large public university in the southern United States for the years 2014–2018. The study examined articles produced by the faculty over the last five years, as well as their cited references and citing articles, in an attempt to establish a list of core journals for business and uncover potential gaps in coverage. Implications for collection development are addressed, as are the benefits for early-career librarians or those unfamiliar with the publishing behaviors of a newly assigned subject discipline. 相似文献

Lower extremity injuries have immediate and long-term consequences. Lower extremity movement assessments can assist with identifying individuals at greater injury risk and guide injury prevention interventions. Movement assessments identify similar movement characteristics and evidence suggests large magnitude kinematic relationships exist between movement patterns observed across assessments; however, the magnitude of the relationships for electromyographic (EMG) measures across movement assessments remains largely unknown. This study examined relationships between lower extremity kinematic and EMG measures during jump landings and single leg squats. Lower extremity three-dimensional kinematic and EMG data were sampled from healthy adults (males = 20, females = 20) during the movement assessments. Pearson correlations examined the relationships of the kinematic and EMG measures and paired samples t-tests compared mean kinematic and EMG measures between the assessments. Overall, significant moderate correlations were observed for lower extremity kinematic (ravg = 0.41, rrange = 0.10–0.61) and EMG (ravg = 0.47, rrange = 0.32–0.80) measures across assessments. Kinematic and EMG measures were greater during the jump landings. Jump landings and single leg squats place different demands on the body and necessitate different kinematic and EMG patterns, such that these measures are not highly correlated between assessments. Clinicians should, therefore, use multiple assessments to identify aberrant movement and neuromuscular control patterns so that comprehensive interventions can be implemented. 相似文献
