This study quantitatively examined reasons for substance use among individuals with psychotic disorders and explored the relationship of these reasons to substance use problems and dependence. Sixty-nine people with psychotic disorders were interviewed using a battery of questionnaires called the Substance Use Scale for Psychosis (SUSP). Symptoms and medication side effects were also measured. ...

Results: The overall prevalence of sunbed use was 39.2% (ever users); 14.6% had used a sunbed within the last 12 months (current users). Among minors and persons with skin types I or II, this proportion was 5.2% and 8.9%, respectively. Positive determinants of current sunbed use (quantified as odds ratios [95% CIs]) were female sex (1.97 [1.64-2.37]), immigrant background (1.46 [1.211.77]), and...

OBJECTIVE To examine the prevalence, correlates and motivations for the commission of property and violent crime amongst a sample of people who inject drugs (PWID). METHOD Data were obtained from the 2013 Illicit Drug Reporting System (IDRS), which includes a cross-sectional sample of 887 PWID. RESULTS Eighteen percent of PWID had committed a property offence and 3% had committed a violent ...

The uses and gratifications theoretical framework has continued to prove useful in the study of new and emerging media. In previous research on television as a medium, motivations for media use have been grouped into either process gratifications (motivations associated with using the medium, like channel surfing) or content gratifications (motivations related to information or entertainment de...

Companies' Facebook pages have emerged as a commonly used marketing channel but consumers' underlying motivations to use these pages and their effect on members' intentions to purchase the host company's products are currently unclear. The present study examines consumers' hedonic and utilitarian motivations to use company-hosted Facebook pages in relation to the community usage behavior (brows...

At cardiac catheterization, the effect of isoproterenol on coronary blood flow was compared in six patients with normal coronary arteries and normal left ventricular function, and eight patients with angiographically defined coronary lesions. Coronary blood flow was measured by selective coronary artery injection of xenon-133 and external monitoring of disappearance curves with a dual probe, di...

We report microstructural design via control of BaZrO3 (BZO) defect density in high temperature superconducting (HTS) wires based on epitaxial YBa2Cu3O7-δ (YBCO) films to achieve the highest critical current density, Jc, at different fields, H. We find the occurrence of Jc(H) cross-over between the films with 1-4 vol% BZO, indicating that optimal BZO doping is strongly field-dependent. The matc...

In the emerging CMC genre of online reviews, lay people, as opposed to professional writers, evaluate products and services, and they receive no pay for their time or effort. This chapter examines possible motivations for writing reviews, particularly efficacy and altruism. In addition, this chapter examines a sample of 640 online reviews to see whether a positive bias existed; indeed, over 48 ...
