Gender Games     

Chad Painter  Patrick Ferrucci 《Journalism Practice》2017,11(4):493-508

This textual analysis focuses on the portrayal of female journalists in House of Cards. The uneven depictions of six female journalists could have a socializing effect on the audience. The researchers argue that the character Zoe Barnes is depicted as childlike, unprofessional, and unethical, while the character Ayla Sayyad is portrayed as a dedicated watchdog journalist. The researchers then explore the ethical implications of these portrayals through the lens of social responsibility theory.  相似文献   

“Why Aren’t You a Sassy Little Thing”: The Effects of Robot-Enacted Guilt Trips on Credibility and Consensus in a Negotiation     

Brett Stoll  Chad Edwards  Autumn Edwards 《Communication Studies》2016,67(5):530-547

Robots are becoming increasingly popular in social applications and have demonstrated effectiveness in a variety of contexts such as education, health, task management, and other complex cooperative roles. The purpose of this study was to examine human–robot interaction in a nonassistive environment: a negotiation scenario. Specifically, the authors examined what effect message appeals (guilt trip, no guilt trip) and robot agency (principal, agent) had on the negotiation outcomes and perceptions of credibility. Results indicated a significant main effect of agency and an interaction effect between agency and guilt messaging on perceptions of robot credibility such that participants rated a robot agent employing no guilt trips as more credible than one negotiating as principal or one utilizing guilt trips. Neither guilt nor agency had a significant effect on the overall concession of the negotiation task.  相似文献   

STATE SUPPORT FOR INTERINSTITUTIONAL TRANSFER AND ARTICULATION: THE IMPACT OF DATABASES AND INFORMATION SYSTEMS     

John F. Welsh  Chad Kjorlien 《Community College Journal of Research & Practice》2013,37(4):313-332

Research since the mid-1960s has demonstrated the relative paucity of state support for the transfer function of postsecondary institutions, particularly community colleges, while emphasizing the importance of support for student access to the full range of higher education opportunities. Ewell and Jones (1991) and Russell (1999) however, have documented that the state policy and planning environment for student transfer changed in the 1990s. At least 43 states, plus Puerto Rico, have ongoing student information systems that include data elements pertaining to transfer students and, thus, have the capacity to affect the transfer environment through data-based analysis of transfer student educational outcomes. This article presents the results of a national study of the purpose, structure, and impact of databases and information systems maintained on transfer students by state higher education agencies. The study concluded that, although most states have an increasing ability to collect, manipulate, and use such data to inform the policy process, state higher education agencies generally do not monitor or assess the effectiveness of their databases and information systems to help improve outcomes for transfer students. A major challenge for state higher education agencies and state policy makers is to develop measures and strategies for determining the effect of state and institutional policies on transfer students.  相似文献   

EMOTIONAL AND BEHAVIORAL PROFILE ASSESSMENT USING THE BASC‐2 WITH KOREAN MIDDLE SCHOOL STUDENTS     

Christine Myunghee Ahn  Chad Ebesutani 《Psychology in the schools》2015,52(8):756-772

Korean middle school students are experiencing high rates of behavioral and emotional problems, suggesting a need for comprehensive screening instruments with strong psychometric properties in school settings. The present study investigated the utility of the Behavior Assessment System for Children‐2 Self‐Report of Personality, Adolescent Form (BASC‐2 SRP‐A) to assess clinical problems and adaptive strengths among Korean middle school students. For this revalidation study of the BASC‐2, we first translated the BASC‐2 SRP‐A into Korean (K‐BASC‐2 SRP‐A). Then, using a total of 458 Korean middle school students aged 12 to 15 years, we examined the factor structure and reliability of the clinical, adaptive, and composite scale scores of the K‐BASC‐2 SRP‐A. We also used a separate sample of 45 middle school students to examine the convergent validity of a subset of the K‐BASC‐2 SRP‐A scales targeting the common problem areas of anxiety, depression, and inattention. Based on the current results, we found strong psychometric properties of the K‐BASC‐2 SRP‐A for use among adolescents in Korea, including a well‐fitting factor structure consistent with the originally proposed model, adequate reliability estimates, and validity coefficients falling in the acceptable range. The K‐BASC‐2 SRP‐A can offer the Korean school mental health field a useful and much‐needed multidimensional screening measure for middle school youths.  相似文献

Is there a low-back cost to hip-centric exercise? Quantifying the lumbar spine joint compression and shear forces during movements used to overload the hips     

Frost DM  Beach T  Fenwick C  Callaghan J  McGill S 《Journal of sports sciences》2012,30(9):859-870

The aim of this study was to quantify joint compression and shear forces at L4/L5 during exercises used to overload the hips. Nine men performed 36 "walking" trials using two modalities: (1) sled towing and (2) exercise bands placed around the ankles. Participants completed forward, backward, and lateral trials with bent and straight legs at three separate loads. Surface electromyography (EMG) was recorded bilaterally from eight torso and thigh sites, upper body and lumbar spine motion were quantified, and hand forces were measured. An EMG-driven musculoskeletal model was used to estimate the muscular contribution to joint compression and shear. Peak reaction, muscle and joint compression and shear forces, and peak gluteus medius and maximus activity were calculated. Significant differences were noted in each dependent measure; however, they were dependent on direction of travel, leg position, and load. The highest joint compression and shear forces for the sled and band conditions were 4378 N and 626 N, and 3306 N and 713 N, respectively. In general, increasing the band tension had little effect on all dependent measures, although a load-response was found during the sled conditions. Before using any exercise to improve hip function, the potential benefits should be weighed against "costs" to neighbouring joints.  相似文献

Initial Validity Evidence for the State Mindfulness Scale for Physical Activity With Youth     

Sarah Ullrich-French  Anne Cox  Amy Cole  Brittany Rhoades Cooper  Chad Gotch 《Measurement in physical education and exercise science》2017,21(4):177-189

Experiencing mindfulness during movement-based interventions (e.g., yoga) may help support adaptive physical activity motivation processes in youth. However, there is currently no measure for assessing state mindfulness with youth within the context of physical activity. The purpose of this study was to qualitatively and quantitatively evaluate a measure of state mindfulness for physical activity in youth. In study one, cognitive interviews with youth (N = 15) ages 8–13 evaluated the State Mindfulness Scale for Physical Activity item comprehension and preference for developmentally worded modifications. Results suggest that problems with item comprehension were more likely in youth younger than 10. In study two, the State Mindfulness Scale for Physical Activity, or a modified version, was administered randomly to middle-school students (N = 481). Internal consistency reliability, confirmatory factor analyses, model-based reliability omega, and correlations with theoretically relevant variables combined with the qualitative evidence provided stronger initial support for the use of the original State Mindfulness Scale for Physical Activity with middle-school students.  相似文献   

Neural adaptations with sport-specific resistance training in highly skilled athletes     

Judge LW  Moreau C  Burke JR 《Journal of sports sciences》2003,21(5):419-427

The aim of this study was to assess the effects of variations in the volume and intensity of resistance training in highly skilled athletes on neural adaptive mechanisms: the maximality and pattern of neural drive. The maximality of muscle activation was measured using a high-resolution sample and hold amplifier to record interpolated twitches. The pattern of neural drive was measured by analysing isometric torque-time curves and electromyographic (EMG) characteristics during the performance of rapid isometric contractions at maximal effort. The volume and intensity of training were varied at 4-weekly intervals to systematically emphasize the development of strength, power and motor performance in 14 highly skilled track and field athletes (e.g. discus, hammer, javelin, shot put and weight). Knee extension strength increased significantly by 15% during steady maximal isometric contractions and by 24% during rapid isometric contractions at maximal effort after the 16-week training programme (P < 0.05). Increases in EMG amplitude and rate of EMG activation indicated that improvements to the pattern of neural drive occurred with sport-specific resistance training (P < 0.05). The maximality and pattern of neural drive did not change in the control group.  相似文献
