Condom use across casual and committed relationships: The role of relationship characteristics.

Background: While the existence of a complex variety of casual sexual relationships (CSRs) has been acknowledged, studies rarely describe the prevalence of condom use across these relationships or how their hybrid nature, specifically relationship characteristics, affect condom use. This study aims to describe condom use within committed relationships and various types of casual sexual relationships (CSRs), examining the influence of relationship characteristics on condom use among culturally validated relationship types (committed, friends with benefits, hookups, booty call).

Methods: Emerging adults (N = 728, 18-29 years, M = 22.

Photoelectrochemical Determination of Cardiac Troponin I as a Biomarker of Myocardial Infarction Using a BiS Film Electrodeposited on a BiVO-Coated Fluorine-Doped Tin Oxide Electrode.

A sensitive and selective label-free photoelectrochemical (PEC) immunosensor was designed for the detection of cardiac troponin I (cTnI). The platform was based on a fluorine-doped tin oxide (FTO)-coated glass photoelectrode modified with bismuth vanadate (BiVO) and sensitized by an electrodeposited bismuth sulfide (BiS) film. The PEC response of the BiS/BiVO/FTO platform for the ascorbic acid (AA) donor molecule was approximately 1.

A low-cost carbon-based electrochemical platform for determining 2,3-dihydroxyphenol: applications in natural water and biodiesel samples.

2,3-Dihydroxyphenol (DHP) is a phenolic compound that has been used as an additive in biodiesel to avoid the auto-oxidation of biofuels and also in the production of cosmetic products. However, this substance can be released into the environment during its manufacture, transport, disposal and industrial use and can be harmful to health due to its toxicity, and hence, monitoring its presence in different samples is very important. Therefore, this work describes an electroanalytical study of DHP using different carbon-based pastes prepared to evaluate which one would be more promising to be used as an electrochemical platform for DHP quantification.

A Fertile Ground for Ambiguities: Casual Sexual Relationships Among Portuguese Emerging Adults.

Casual sexual relationships (CSRs) are frequent relationship experiences in young adulthood that provide opportunities for many to explore sexual relationships and to construct their sexual identity. Empirical research on casual sex is still lacking outside North-American countries, despite evidence pointing to the need to contextualize sexual interactions in their own sociocultural context. In order to better understand casual sexual relationships, these should be examined in with novel samples in other countries where a "hookup culture" as it is described in the North-American university campus is apparently absent.

Still Striving After All These Years: Between Normality of Conduct and Normativity of Evaluation in Casual Relationships among College Students.

Unlabelled: Gender similarities have been detected in various sexual behaviors and attitudes in young adults, but persistent differences remain regarding casual sexual relationships (CSRs), with women feeling different external pressures than men. We set out to study the spontaneous references made to gender similarities and differences towards CSRs in eight focus group interviews ( = 35 college-students, aged 18-28) about the characteristics of CSRs within a social-role framework. The thematic analysis led us to the interpretation that there is an ongoing change in the acceptability of these relationships, leading to the emergence of a single sexual standard - mostly liberal, but at times also conservative.

Clear-Cut Terms and Culture-Sensitive Characteristics of Distinctive Casual Sexual Relationships in Portuguese Emerging Adults.

Unlabelled: Casual sexual relationships (CSR) are increasingly common but limited empirical research has addressed their terminology and distinctive characteristics. This study sought to identify the most clear-cut terms and to consider how culture-sensitive characteristics distinguish casual sexual relationships among Portuguese emerging adults ( = 262, 18-29 years old). We combined two qualitative studies - one by association and another by free recall - to ascertain the clarity of the terms, plus a quantitative study to further characterize and differentiate them.
