Identifying swimmers as water-polo or swim team-mates from visual displays of less than one second

Opportunities for ball passing in water-polo may be brief and the decision to pass only informed by minimal visual input. Since researchers using point light displays have shown that the walking or running gait of familiars can be identified, water-polo players may have the ability to recognize team-mates from their swimming gait. To test this hypothesis, members of a water-polo team and a competition swim team viewed two randomized sets of video clips, each less than one second long, of swimmers from both teams sprinting freestyle past a fixed camera. The arm stroke clip sequence showed only the upper body, and the kick sequence showed only the lower body. After viewing each video clip, observers rated their level of certainty as to whether the swimmer presented was a team-mate or not. Discrimination was significantly above chance in both groups. Water-polo players were better able to identify team-mates from their kick, whereas swimmers were better able to do so by viewing arm stroke. Our results suggest that, as with walking and running gait, small amounts of visual information about swimmers can be used for recognition, and so raise the possibility that specific training may be able to improve team-mate classification in water-polo, particularly in newly formed teams.     

Hypothetical rape scenarios as a pedagogical device to facilitate students' learning about prosecutorial decision-making and discretion

The use of scenarios to facilitate learning about the complexities of prosecutorial decision-making is a useful pedagogical device for facilitating student learning about sensitive criminal justice issues such as rape or sexual assault. It is also useful in helping instructors gain insight concerning the premises students carry with them into the classroom. Hypothetical rape scenarios were presented to 178 students who were asked to make decisions as to whether or not to pursue prosecution. Findings suggest that race, sex, age, and education play significant roles in students' decision-making processes. Furthermore, as the rape scenario becomes more complicated, demographic factors play a heavier hand in arriving at decisions concerning the disposition of a case.     

Unveiling their worlds: the use of dialogue as a health-promotion tool for HIV/AIDS education in a poor community in Kenya

Three decades since the onset of HIV/AIDS, 33.2 million people worldwide are infected and prevalence in Kenya is on the rise. This paper contributes to discussions about HIV/AIDS education and draws on the health promotion approach and the emancipatory theory of Paulo Freire. Freire argued that through dialogue people unveil their world. The researchers used the method of dialogue to facilitate parents' and teachers' reflections on sexuality education for the children. The dialogues seemed to facilitate some reflection and showed the attitudes of the community to matters that impact on sexuality education (e.g. gender and sexuality). This paper illustrates how dialogic processes can be useful to the process of constructing realistic and contextually relevant HIV/AIDS education. The challenges for the researcher as an outsider are also discussed.     

Merck's One Less Campaign: Using Risk Message Frames to Promote the Use of Gardasil® in HPV Prevention

In 2006, Merck introduced Gardasil® through its One Less campaign, highlighting how the vaccine protects against the transmission of human papillomavirus (HPV) and, potentially, cervical cancer. The purpose of this study was to determine how young women learned about Gardasil and if the One Less campaign influenced the patient's decision to receive/decline the vaccines. Participants primarily learned about Gardasil from television advertising, and felt the campaign addressed the psychometric paradigm hazard factors of control and dread associated with HPV. However, participants reported that physicians/physician's assistants and mothers remained the primary sources of influence when choosing to receive/decline the vaccine series.     

Student perceptions of satisfaction and anxiety in an online doctoral program

Eighty-four students in an online health education doctoral program taking the first course in the program over one year (four quarters) were surveyed in regards to their computer, Internet, and online course anxiety, and overall course satisfaction. An 18-item anxiety tool with domains in computer, Internet, and online learning was administered in the first and last weeks of an educational research course to assess for changes in student anxiety. A 24-item satisfaction tool with domains regarding the instructor, technology, setup, interaction, outcomes, and overall satisfaction was administered at the end of the course. Results show a significant negative correlation between anxiety and student satisfaction. Student anxiety levels were in the relatively moderate range; changes in anxiety levels over time were not significant. Participants who felt anxious when using computers or the Internet, or when taking online courses experienced anxiety with other domains.
