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...

A small subset of information visualization and the digital humanities focuses on casual users, that is, users in everyday, non-work contexts. The development of digital cultural heritage collections like Europeana.eu for the general public increases the importance of this user group. This position paper reviews parallel findings from both research fields on casual users, their goals and explor...

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 ...

We present a proposal for the annotation of factuality of event mentions in Spanish texts and a free available annotated corpus. Our factuality model aims to capture a pragmatic notion of factuality, trying to reflect a casual reader judgements about the realis / irrealis status of mentioned events. Also, some learning experiments (SVM and CRF) have been held, showing encouraging results.

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...
