Baseball

The purpose of this study was to quantify and compare kinematic, temporal, and kinetic characteristics of American and Korean professional pitchers in order to investigate differences in pitching mechanics, performance, and injury risks among two different cultures and populations of baseball pitchers. Eleven American and eight Korean healthy professional baseball pitchers threw multiple fastball pitches off an indoor throwing mound positioned at regulation distance from home plate. A Motion Analysis three‐dimensional automatic digitizing system was used to collect 200 Hz video data from four electronically synchronized cameras. Twenty kinematic, six temporal, and 11 kinetic variables were analyzed at lead foot contact, during the arm cocking and arm acceleration phases, at ball release, and during the arm deceleration phase. A radar gun was used to quantify ball velocity. At lead foot contact, the American pitchers had significantly greater horizontal abduction of the throwing shoulder, while Korean pitchers exhibited significantly greater abduction and external rotation of the throwing shoulder. During arm cocking, the American pitchers displayed significantly greater maximum shoulder external rotation and maximum pelvis angular velocity. At the instant of ball release, the American pitchers had significantly greater forward trunk tilt and ball velocity and significantly less knee flexion, which help explain why the American pitchers had 10% greater ball velocity compared to the Korean pitchers. The American pitchers had significantly greater maximum shoulder internal rotation torque and maximum elbow varus torque during arm cocking, significantly greater elbow flexion torque during arm acceleration, and significantly greater shoulder and elbow proximal forces during arm deceleration. While greater shoulder and elbow forces and torques generated in the American pitchers helped generate greater ball velocity for the American group, these greater kinetics may predispose this group to a higher risk of shoulder and elbow injuries.     

An Informed Look at Doctoral Vivas (Oral Examinations) in the Preparation of Counselor Educators

Viva voce is the Latin expression traditionally used to refer to doctoral oral examinations. Viva voce, or simply viva, examinations are a standard requirement for doctoral candidacy and degree completion in many counselor education programs. Despite the prevalent use of vivas as an assessment and learning tool, the counselor education literature is scant on information about their rationale, method, and impact. Current trends toward transparency and accountability in higher education now require that counselor educators and researchers take steps to ensure that the use of vivas is justified beyond tradition alone.     

Within-Year Retention Among Ph.D. Students: The Effect of Debt,Assistantships, and Fellowships

This study employs the 2007–2008 National Postsecondary Student Aid Study and the National Research Center’s survey data, “A Data-Based Assessment of Research-Doctorate Programs in the United States,” to investigate the (1) the effects of debt in relation to tuition and fees paid and (2) the effects of teaching assistantships, research assistantships, and fellowships on within year retention among Ph.D. students. We created an innovative conceptual model for this study by merging a socioeconomic model for graduate students and a graduate student socialization model. We used propensity score weights for estimating average treatment effects and average treatment effect on the treated as well as a series of control and balancing variables. This study provides timely insights into which of these financial strategies are likely to improve the already low doctoral retention rates nationwide. To the best of our knowledge, this is the first study that includes proxies of socialization variables in examining the role of various funding mechanisms in doctoral retention using a national representative dataset.     

FAST-Future Academic Scholars in Teaching: A High-Engagement Development Program for Future STEM Faculty

Doctoral granting institutions prepare future faculty members for academic positions at institutions of higher education across the nation. Growing concerns about whether these institutions are adequately preparing students to meet the demands of a changing academic environment have prompted several reform efforts. We describe a professional development model designed to prepare the future faculty to integrate the multiple components of academic careers. The program emphasizes the study and application of effective teaching practices centered on student learning and assessment and expectations for faculty careers. We describe the impact of the program on its participants.     

Newspapers' Struggles with Civic Engagement: The U.S. Press and the Rejection of Public Journalism as Propagandistic

This article examines how two factors—journalism's professionalized vigilance against co-option and its difficulty differentiating social action communications from propaganda—led to many in the press attacking public journalism as propagandistic. Sociologist Alfred McClung Lee's mid-20th century writings provide fresh explanations for how press critics conflated public journalism with propaganda. Finally, this article maintains that newspapers can improve their pertinence in a new media age by better linking citizen voices into news stories.     

Communication apprehension and the type‐a personality

Do Type‐A individuals experience communication apprehension? Consistent with theoretical expectations, the data at hand suggest the answer is a qualified “no.” Individuals evidencing a Type‐A personality reported significantly less CA than their Type‐B counterparts. This pattern of findings was strongest for apprehension about communicating in “collective” contexts (e.g., public, group, meeting) but diminished for CA in more “intimate” circumstances (e.g., interpersonal).     

The somatic marker as a “short cut” to verbal immediacy

This study examined the relationships between the somatic‐marker hypothesis, developed by Damasio (1994) as it relates to homophily and verbal immediacy in the classroom. Damasio has hypothesized that when particular events occur in one's life, there is a “memory” of that event in the brain. As a result, when a similar event occurs, the somatic marker recreates that first event. Students were provided three different scenarios about the first day of a communication class. In the scenarios, the instructor presented information about himself. One instructor provided only autobiographical, demographic data (the control). Another provided information hozu he had had difficulty with public speaking (the selfish marker). The third provided information about how the instructor had helped someone else who had difficulty in public speaking (the altruistic marker). The results indicated that while homophily differences were not significant, there was a significant difference between the control group and the altruistic marker.     

Cronbach's Alpha Versus Components of Variance Approach (COVA): Dispelling Three Myths about Alpha and Suggesting an Alternative Reliability Statistic for Communication Trait Research

This study examined the effects of sociocultural factors and perceptions of mental illness on preferences for indirect disclosure. We surveyed 354 college students from China and the U.S. The results indicated that (a) males and members of the collectivistic culture reported more stigmatized attitudes; (b) stigma endorsement was positively associated with preferences for indirectness; and (c) males, members of the collectivistic culture, and individuals without previous interpersonal contact with someone with a mental illness were more likely to recommend an indirect disclosure strategy. The findings demonstrate the importance of considering how sociocultural factors can affect individuals’ preferences for disclosing stigmatized identities.     

ACT UP 25: HIV/AIDS,Archival Queers,and Mnemonic World Making

Audre Lorde's speech, “The Transformation of Silence into Language and Action, “sheds light on the margins of rhetoric in the sense of the public speech because she examines factors that may cause some people to remain silent while enabling others to speak and act. “Margins” refers both to the parameters employed for defining a practice and the relative place or value of varied activities exemplifying the practice. Lorde interweaves her commentary on the silence surrounding breast cancer with insights about silence drawn from her experiences as a member of several subordinated communities, especially as they relate to the misuse of power to silence those who are different. Her speech comments on silencing and power, sexism, verbal abuse, violence and sexualized aggression, shame, the taboo, and hostile social environments. Paradoxically, Lorde's speech is as much about the possibilities of rhetoric as its limits.
