The effect of stud configuration on rotational traction using the studded boot apparatus

Due to its associated injury risk, rotational traction is a frequently measured natural turf surface property. The most commonly used equipment, the studded boot apparatus (SBA), consists of a circular stud configuration that does not replicate the stud pattern on a regular football boot and may under or over estimate the surface traction. The aim of this study was to establish potential differences in the rotational traction measured between the current stud configuration on the SBA and the stud configuration on the most commonly used Australian football boots. The original studded boot had significantly higher rotational traction than the moulded stud sole or bladed sole. Location, quality and time tested all interacted significantly with the rotational traction measured. The current SBA may not accurately represent the rotational traction experienced by football players, and consequently may not be the most appropriate configuration to assess the relationship between rotational traction and injuries.     

Of Sad Men and Dark Comedies: Mood and Gender Effects on Entertainment Media Preferences

Although traditional mood management theory suggests we use media to deflect sad moods and maintain good moods, various research findings reflect a more complex picture. The present study took a mixed-method, nuanced approach to basic mood management questions and investigated both open and close-ended media preferences among college students (N = 157) immediately following a positive or negative mood induction. Results show that sad (vs. happy) participants showed a preference for viewing a dark comedy or a social drama, whereas happy (vs. sad) participants showed a preference for viewing a slapstick comedy or an action adventure. Women (vs. men) showed an increased preference for romantic genres regardless of mood, whereas men showed a preference for action, suspense, and dark comedy genres. An interaction between gender and mood also emerged; sad men in particular showed a preference for dark comedies. Results are discussed in light of the emotional gratifications that mood-reflecting media may afford men and women.     

Invalidated identities: The disconfirming effects of racial microaggressions on Black doctoral students in STEM

Black students face repeated racial microaggressions that may challenge their mental health and academic performance in engineering doctoral programs. Researchers attribute this to stereotypes and institutional climates that juxtapose their STEM and racial identities as incongruent. In this article, we analyzed the perceptions of environmental, behavioral, and verbal racial microaggressions of 33 Black doctoral students and postdocs, with a focus on their interactions with non-Black peers. Data were collected through semi-structured interviews with Black doctoral students from 11 Predominantly White Institutions in the United States. To analyze the experiences of our participants, we utilized two theoretical frameworks: Racial microaggressions and identity nonverification. Across the interviews, participants described various forms of racial microaggressions that greatly challenged their sense of belonging and identities as engineers. This research affirms the need to develop initiatives at the departmental and institutional levels to encourage more inclusive spaces for diverse students in STEM doctoral programs and to combat the types of exclusionary practices found in this study.     

The impact of a prejudice-prevention television program on young children’s ideas about race

Two studies investigated whether children’s television programs that were produced to decrease racial prejudice had the intended positive effect on young children. Study 1 measured 60 White 5- and 6-year-old children’s attitudes toward Asian, Black, and White stimuli prior to, and immediately following, a brief, one-time anti-prejudice television program. No significant change was observed. Study 2 assessed the attitudes of 30 White 3–6-year-old children toward Asian, Black, Hispanic, and White stimuli at the beginning and end of a 3-week intervention period. During the intervention period children watched a pro-diversity television program four times. Plot and anti-prejudice message comprehension was assessed at three time-points during the testing period. Participants improved on plot and message comprehension over time, but no change in ideas about race was evidenced (children indicated a strong pro-White bias at both pre- and post-test). Possible reasons for, and implications of, this lack of change are discussed.     

The Benefits and Trajectory of Digital Editing-Based Media Literacy Among Girls

The societal thin-ideal for women is damaging to the body image of both adults and children. Women representing this thin-ideal in the media are now digitally edited (airbrushed/Photoshopped), creating unachievable goals. A growing body of literature has proposed media literacy training and investigation to help combat the damage of these images on body image. This study assessed the knowledge and impact of digital editing in four female age groups (i.e., 3rd grade, 7th grade, 11th grade, and college students) collected in the U.S. state of Ohio. A within-subjects experimental design both extended previous work on media literacy by examining body image pre- and postexposure to edited images and investigated digital editing knowledge reflection as an intervention on body image harm. The current study also assessed the digital editing knowledge of all participants, creating an age trajectory. College-age emerging adults’ body image decreased after exposure to digitally edited images. However, this decline in body image was smaller when engaging in digital editing reflection. On average, younger participants did not show a decrease in body image after exposure. Results also indicated that girls begin to learn about digital editing around 12 to 13 years of age.     

The estimation of a conceptual model of nontraditional undergraduate student attrition

The purpose of this study was to estimate a conceptual model of nontraditional student attrition. Data were gathered from 624 nontraditional (commuter, part-time) freshmen at a midwestern urban university enrolling 22,000 students. For these nontraditional students, dropout was a function of GPA and credit hours enrolled, as well as the utility of education for future employment, satisfaction with the student role, opportunity to transfer, and age affecting dropout through intent to leave. In addition, absence from class, age, high school performance, and ethnicity had indirect effects on dropout through GPA. These results suggested that nontraditional students dropped out of college for academic reasons or because they were not committed to attending the institution, but their reasons for leaving were unrelated to social factors at school. The findings helped validate the conceptual model.An earlier version of this paper was presented at the annual meeting of the American Educational Research Association, San Francisco, April 1986.     

Concept Availability in the Causal Inferences of Children and Adults

What supplies the concepts in causal inferences in story comprehension? This question was examined in 5 experiments. Elementary school children and college students listened to stories containing a "premise" sentence describing a character's intent in initiating a series of actions, followed by an unexpected "outcome." After each story, the subjects were asked inference questions about the reason for the outcome (Experiments 1-4) or asked to explain the outcome (Experiment 5). In the various experiments, the availability of object concepts for an inference was manipulated by providing 0 or 2 clues preceding the outcome, additional filler information that diluted the clue information, a mention of an object in the premise or no mention, and an object title for each story or no title. The results suggested that the availability of an object concept in sentences prior to the outcome was a critical determinant of whether an object inference occurred, especially for children. Given availability, the thematic prominence of the object influences whether the object will be used in an inference.     

Students Promoted Despite Test Failure

No Child Left Behind (NCLB) dictates students in Grades 3, 5, and 8 pass state tests to be promoted. Accordingly, most state education codes require students to pass reading and math exams for promotion. The majority of those who fail, however, appear to be promoted anyway. This article addresses core questions concerning the paradigm under which NCLB operates, what it means to promote or retain a student, and the consequences of these actions.     

The Impact of School Improvement Grants on Student Outcomes: Findings From a National Evaluation Using a Regression Discontinuity Design

As part of the American Recovery and Reinvestment Act of 2009, the School Improvement Grants (SIG) program received more than $3 billion with the goal of substantially improving student achievement. The SIG program’s funding was to help states turn around the nation’s persistently lowest-achieving schools using one of four school intervention models—transformation, turnaround, restart, or closure. We used a regression discontinuity design and a large sample of schools from more than 20 states to evaluate the impact of implementing a SIG-funded intervention model on use of SIG-promoted practices and student outcomes. Our regression discontinuity design exploited cutoff values on the continuous variables used to define the SIG eligibility tiers to compare outcomes in schools that just met the eligibility cutoff for receiving SIG funding to outcomes in schools that just missed it. We found that SIG had no impact on any of the outcomes we examined, including math and reading test scores, high school graduation rates, and college enrollment rates. Using a correlational analysis, we found the turnaround model was associated with larger student achievement gains in math than the transformation model for grades 6 through 12.
