(Press-News.org) March 24, 2014 -- Online sexual hook-ups present a unique opportunity to explore many factors of decision-making that inform sexual health. A study conducted by Eric Schrimshaw, PhD, at Columbia University's Mailman School of Public Health and Martin J. Downing, Jr., PhD, of the National Development and Research Institutes, found evidence that men having sex with men use the Internet to find sexual partners who do not identify as gay, either to fulfill a fantasy or because it allows anonymous sexual encounters without discovery. The findings are online in the journal, Psychology of Sexual Orientation and Gender Diversity, published by the American Psychological Association.
To examine the subgroup of men seeking non-gay-identified (NGI) men in the online sexual marketplace, the researchers reviewed 1,200 Internet personal ads posted on Craigslist and selected 282 for analysis and performed comparisons of two categories of personal ads: those seeking encounters with NGI men, including straight, bisexual, married, curious, and men on the "down low" (those who usually identify as heterosexual but have sex with men); and a contrasting set of ads that did not specifically seek NGI men. Craigslist was chosen because it is publicly accessible, highly trafficked, free-of-charge, and widely used by gay, NGI men seeking men, or men who have sex with men and women to find sexual partners.
Among the ads studied, 11% were placed by men seeking NGI partners. Although men who posted NGI-seeking ads were more likely to self-identify as bisexual, married, and/or discreet and to seek out an anonymous encounter relative to the ads of comparison men, only 24% of online advertisements seeking NGI men were posted by men who were themselves non-gay-identified. This suggests that many of the posts are placed by gay men seeking NGI men, perceived by some gay men to be more masculine, dominant, or "straight-acting."
Only a small number of ads by NGI-seeking men mentioned safe sex or condom use. The analysis revealed that men seeking NGI partners were significantly less likely to mention that they wanted to have safer sex/use condoms (15% vs. 33%) and were more likely (66% vs. 42%) to omit mention of condoms or safer sex in their advertisements. "This suggests that these men are more likely to be looking for and willing to engage in sex without a condom which may place them at greater risk for HIV/STI transmission than men who are not seeking non-gay-identified male partners," said Dr. Schrimshaw, who is assistant professor of Sociomedical Sciences at the Mailman School of Public Health.
Although few advertisements posted by men seeking NGI partners specifically sought anal sex without a condom (1% vs. 2%), they were significantly more likely to seek oral sex without a condom (14% vs. 5%) than comparison advertisements. "Future research on NGI-seeking men could lead to better understanding of their risk behaviors which, in turn, could be helpful for developing and targeting HIV/STD prevention and intervention efforts," noted Dr. Schrimshaw.
"Men having sex with men with characteristics that are devalued in the sexual marketplace such as older, heavier, or less masculine men will perhaps have less bargaining power, or at least perceive themselves as having less power, therefore, they may be willing to place themselves at risk for HIV and other sexually transmitted diseases to obtain a sexual partner," said Dr. Downing. These findings suggest that men may be even more willing to do this with NGI men.
The findings have unique implications for sexual health research targeting non-disclosing, NGI MSM and their same-sex partners. The authors note that further investigation is warranted to determine the extent to which NGI-seeking men are successful in finding partners for same-sex encounters who identify as straight or heterosexual, bisexual, down-low, or married as well as the types of behaviors these men engage in and the level of sexual risk.
"Regardless of any study limitations, the research has allowed us to document the existence of a subgroup of men who actively seek out sexual encounters with men who do not identify as gay," said Dr. Schrimshaw. "Moreover, the findings suggest that men with a preference for NGI men attempt to alert such prospective partners through a combination of self-described characteristics, desired partner attributes, and behavioral preferences, all of which serve to attract more discreet and masculine men. Given the attention to the sexual behaviors of NGI MSM, the results of this study support the need for additional research to investigate the behavioral outcomes of NGI-seeking men's personal ads."

Adult day-care services boost beneficial stress hormones in caregivers
2014-03-24
Family caregivers show an increase in the beneficial stress hormone DHEA-S on days when they use an adult day care service for their relatives with dementia, according to researchers at Penn State and the University of Texas at Austin.
DHEA-S controls the harmful effects of cortisol and is associated with better long-term health.
"This is one of the first studies to show that DHEA-S can be modified by an intervention, which in our case, was the use of an adult day care service," said Steven Zarit, Distinguished Professor of Human Development and Family Studies, Penn ...
Parallel programming may not be so daunting
2014-03-24
Computer chips have stopped getting faster: The regular performance improvements we've come to expect are now the result of chipmakers' adding more cores, or processing units, to their chips, rather than increasing their clock speed.
In theory, doubling the number of cores doubles the chip's efficiency, but splitting up computations so that they run efficiently in parallel isn't easy. On the other hand, say a trio of computer scientists from MIT, Israel's Technion, and Microsoft Research, neither is it as hard as had been feared.

New perspective for soil clean-up: Microscopic ciliates transport poisonous tar substances
2014-03-24
You must use a microscope to spot the new helpers that can assist in biological soil clean-up (bioremediation). They are small, mobile microorganisms, such as the unicellular slipper-shaped ciliates that can be found in stale water in a flower vase, where they feed on bacteria. New results from Aarhus University indicate that such mobile microorganisms can play a surprising key role in bioremediation of soil which is contaminated with so-called PAHs (Polycyclic Aromatic Hydrocarbons).
PAH are toxic tar substances formed during incomplete combustion in, for example, car ...
New technique for identifying gene-enhancers
2014-03-24
An international team led by researchers with the Lawrence Berkeley National Laboratory (Berkeley Lab) has developed a new technique for identifying gene enhancers - sequences of DNA that act to amplify the expression of a specific gene – in the genomes of humans and other mammals. Called SIF-seq, for site-specific integration fluorescence-activated cell sorting followed by sequencing, this new technique complements existing genomic tools, such as ChIP-seq (chromatin immunoprecipitation followed by sequencing), and offers some additional benefits.
"While ChIP-seq is very ...
Smokers' bitter taste buds may be on the fritz
2014-03-24
Smokers and those who have quit cannot fully appreciate the full flavor of a cup of coffee, because many cannot taste the bitterness of their regular caffeine kick. This is the finding of a study led by Nelly Jacob of the Pitié-Salpêtrière Hospital APHP in France, published in Springer's journal Chemosensory Perception.
It is already known that smoking, and especially the toxic chemicals in tobacco, causes a loss of taste among smokers. It also causes structural changes to the fungiform papillae of the tongue where the taste buds are located. However, it is not yet known ...

2014-03-24
This news release is available in Spanish.
A research study, participated in by Universidad Carlos III de Madrid (UC3M), has discovered that nanometric-size foam structures follow the same universal laws as does soap lather: small bubbles disappear in favor of the larger ones.
The scientific team, made up of researchers from the Consejo Superior de Investigaciones Científicas (Spanish National Research Council) - CSIC, the Universidad Pontificia Comillas de Madrid- UPCO, and UC3M, reached this conclusion after producing and characterizing nanofoam formed by ion ...
Plugging the hole in Hawking's black hole theory
2014-03-24
EAST LANSING, Mich. --- Recently physicists have been poking holes again in Stephen Hawking's black hole theory – including Hawking himself. For decades physicists across the globe have been trying to figure out the mysteries of black holes – those fascinating monstrous entities that have such intense gravitational pull that nothing – not even light – can escape from them. Now Professor Chris Adami, Michigan State University, has jumped into the fray.
The debate about the behavior of black holes, which has been ongoing since 1975, was reignited when Hawking posted a ...
Patient enrollment, use, and satisfaction with patient portals
2014-03-24
Many physicians are adopting patient portals in response to governmental incentives for meaningful use (MU), but the stage 2 requirements for portal use may be particularly challenging for newer electronic health record (EHR) users. This study examines enrollment, use based on MU requirements, and satisfaction in a recently-adopting fee-for-service multispecialty system. The Centers for Medicare and Medicaid Services (CMS) financial incentives for meaningful use (MU)1 likely will persuade many reluctant doctors to adopt electronic health records (EHRs). However, there are ...
Research finds moving public assistance payments from cash to plastic cuts crime
2014-03-24
ATLANTA--Counties that change their delivery of public assistance benefits from paper checks to an Electronic Benefit Transfer (EBT) system – using debit cards – see their street crimes drop significantly, according to a study published today by the National Bureau of Economic Research.
Titled "Less Cash, Less Crime: Evidence from the Electronic Benefit Transfer Program," the study is the first to empirically examine whether the introduction of an EBT system, which reduces the amount of cash circulated on the streets, will disrupt criminal activities that rely on the ...
First look at breast microbiota raises tantalizing questions
2014-03-24
The female breast contains a unique population of microbes relative to the rest of the body, according to the first-ever study of the breast microbiome. That study sought to lay the groundwork for understanding how this bacterial community contributes to health and disease, says first author Camilla Urbaniak, a PhD student at the University of Western Ontario. The research was published ahead of print in Applied and Environmental Microbiology.
"Proteobacteria was the dominant phylum in healthy breast tissue," says Urbaniak, noting that it is found only in small proportions ...
