With a focus on Uganda, this paper examines men's condom use in sexual relationships with casual partners and what this might tell us about men's vulnerability to HIV-infection. We carried out repeat interviews with 31 men attending a clinic serving women at high risk for HIV infection and their partners in Kampala. We found that the experience of condom-less sex in the men's youth, itself the ...

We examine whether individuals respond to comparisons involving romantic partners as they would to comparisons involving the self. Four studies (N = 2,210) using recalled (Studies 1-3) and actual (Study 4) comparisons about attractiveness (Study 1) and relationship skills (Studies 2-4) demonstrated that individuals high in self-other overlap decrease domain relevance following upward but not do...

Prior research has shown that negative online reviews are more valuable than positive reviews due to differences in casual attribution for positive versus negative information such that negative reviews tend to be relatively attributed more to the product (vs. reviewer) than positive reviews. We propose that the presence of repeating purchase cues, which indicates using a product for a reasonab...

In healthy adult peripheral nerve, Schwann cells are believed to be generally quiescent. Similarly, cultures of isolated rat sciatic nerve Schwann cells hardly proliferate in serum-supplemented medium. The possibility that Schwann cells negatively regulate their own proliferation was supported by the demonstration that conditioned media from Schwann cell cultures inhibited the proliferation of ...

Previous studies indicated that B7-H4, the youngest B7 family, negatively regulates T cell-mediated immunity and is significantly overexpressed in many human tumors. Tumor stem cells are purported to play a role in tumor renewal and resistance to radiation and chemotherapy. However, the link between B7-H4 and tumor stem cells is unclear. In this study, we investigated B7-H4 expression in the me...

Factors secreted by macrophages contribute to whole body insulin resistance, acting in part on adipose tissue. Muscle is the major tissue for glucose disposal, but how macrophage-derived factors impact skeletal muscle glucose uptake is unknown, or whether the macrophage environment influences this response. We hypothesized that conditioned medium from macrophages pretreated with palmitate or LP...

The variety and availability of casual video games presents an exciting opportunity for applications such as cognitive training. Casual games have been associated with fluid abilities such as working memory (WM) and reasoning, but the importance of these cognitive constructs in predicting performance may change across extended gameplay and vary with game structure. The current investigation exa...

This paper presents a study investigating cooperation between players in casual games. Although widely used in co-located or asynchronous settings, cooperative gameplay elements are not popular in networked synchronous casual games. In our study, we have analyzed different types of cooperation between players in casual games. Each of these is based on a certain cooperative game design pattern, ...

BACKGROUND "Casual sex" is seldom as non-selective and random as it may sound. During each sexual encounter, people consciously and unconsciously seek their casual sex partners according to different attributes. Influential to a sexual network, research focusing on quantifying the effects of physical appearance on sexual network has been sparse. METHODS We evaluated the application of Log odd...

BACKGROUND Every summer, young people flock to nightlife-focused holiday resorts around the world to find casual work. Despite being exposed to hedonistic environments, often for several months, little is known about their substance use, sexual activity and health service needs over this extended amount of time abroad. METHODS A short anonymous questionnaire examining alcohol and drug use, se...
