Young adults are at high risk for acquiring STDs/HIV due primarily to multiple sex partners, unprotected sex, and substance use combined with sexual activity. Contranormative settings--such as the annual spring break vacation--provide ideal conditions for the potentially lethal interaction between alcohol, drugs, and sexual risk-taking. As a steadily growing form of youth travel and characteriz...

Sexting, sending, or receiving sexually suggestive or explicit messages/photos/videos, have not been studied extensively. The aims of this study is to understand factors associated with sexting among minority (e.g., African- American, Hispanic) emerging adult males and the association between sexting and sexual risk. We recruited 119 emerging adult heterosexual males and assessed sexting and se...

Studies show that even though intelligibility is increased by the decrease of speech rate both in clear and casual speech, clear speech can also be produced without the decrease of rate after training the speakers [1]. This suggests that clear speech has inherent acoustic properties independent of rate, that contribute to improved intelligibility. Many speakers in their effort to elicit clear s...

In a traditional Business Intelligence (BI) system, power users serve less experienced casual users. Power users analyze and gather data requested by casual users, and produce the reports and visualizations that casual users base their decisions on. When data volumes and the usage frequency of a traditional BI system increase, power users have problems serving all the requests from casual users...

We present two novel music interaction systems developed for casual exploratory search. In casual search scenarios, users have an ill-defined information need and it is not clear how to determine relevance. We apply Bayesian inference using evidence of listening intent in these cases, allowing for a belief over a music collection to be inferred. The first system using this approach allows users...

OBJECTIVE To examine differences in the AIDS-related knowledge, attitudes and behaviours of first year university undergraduates in 1989 and 1994. DESIGN Comparisons were made between cross-sectional surveys, conducted in 1989 and 1994, of first year undergraduates at three Melbourne universities. RESULTS The 1994 cohort reported more positive attitudes toward, and better knowledge of, safe...

This study examines whether casual work can shorten the time taken to move from unemployment into permanent work using longitudinal data from the Survey of Employment and Unemployment Patterns. The analysis is based on comparison of the transition rate from unemployment to permanent work with the combined transition rates of unemployment to casual work and casual work to permanent work. Hazard ...

BACKGROUND The relationship between sodium intake and blood pressure (BP) is affected by many factors such as absolute level of sodium intake, salt sensitivity, and the accuracy or the timing of the BP measurement. There is no epidemiologic study using both ambulatory BP monitoring (ABPM) and 24-h urine sample in a middle-aged general population. METHODS In the rural area, Yeojoo County, Gyun...

Endogenous opiate peptides can regulate neuroendocrine and circulatory responses to behavioral stress and may be important in the pathogenic effects of sympathoadrenal reactivity. We tested this hypothesis by examining the effect of the opiate antagonist naloxone on blood pressure responses to behavioral stress in young adults with high, medium, or low casual blood pressures. Naloxone increased...

This paper describes an acoustic-phonetic comparison of casual and clear speech styles elicited in read and spontaneous speech. For the spontaneous speech, 20 pairs of English talkers were recorded doing a problem-solving picture task in good and degraded listening conditions. Each person also read sentences in casual and clear styles. The read clear speech was an exaggerated form of clear spee...
