Testing Women’s Trust in Other Women and Same-Sex Attracted Males in Three Cultures

Heterosexual women trust mating-relevant advice received from gay men more than that received from heterosexual women. This trust is predicated on women’s perception that gay men lack ulterior sexual motives and romantically pursue other gay men. However, this trust may not hold in all cultures. For example, in both Samoa and the Istmo Zapotec of Southern Mexico, women take part in mate competition against feminine same-sex attracted males—referred to as fa’afafine and muxe, respectively—who regularly engage in sexual activity with masculine men. The present studies sought to replicate and extend research on women’s trust in males who are same-sex attracted. Experiments were conducted in Canada, Samoa, and the Istmo Zapotec, with women randomly assigned to consider the likelihood of various mate-poaching behaviors performed by either a rival woman or a same-sex attracted male. In Canada, women were more trusting of cisgender gay men than other women. Similarly, Samoan women were more trusting of fa’afafine than other women. In the Istmo Zapotec, women were equally distrustful of women and feminine muxe gunaa, whereas more masculine muxe nguiiu were rated as more trustworthy than women and muxe gunaa. These results illustrate that women’s trust in same-sex attracted males varies both between and within cultural contexts, perhaps impacted by the relative femininity of the male in question.

     

Current Progress on Antibiotic Sensing Based on Ratiometric Fluorescent Sensors

Antibiotics, which can be used as veterinary drugs, are widely used in the prevention and treatment of infectious diseases for animals. However, overuse of antibiotics had caused serious problems on food contamination and human harm. For control such public issues, several of techniques have been in recent years. Ratiometric fluorescent (RF) technique, as one of the most promising strategies for quantitatively evaluated analytes, had been extensively developed for the readily measurements on the two different fluorescent emission intensities. In this review, the construction strategies for recent RF sensors will be mainly focused on. Meanwhile, the recent advances and new tendencies for detection of antibiotics based on RF technique shall be introduced. Finally, outlooks on the opportunities and challenges for quantitative fluorescence sensing on antibiotics will be summarized.

The establishment of the Korean medical device safety information monitoring center: Reviewing ten years of experience

Medical devices may revolutionize healthcare delivery but can lead to serious adverse events for treated patients and users. While reporting of adverse events related to medical devices is an essential starting point for post-market surveillance, underreporting of medical device adverse events is a global problem. Korea introduced a voluntary medical device adverse event reporting system in 2010, called the Medical Device Safety Information Monitoring Center, which has led to an increase in adverse event reports. For 10 years, the Medical Device Safety Information Monitoring Center has analyzed medical device adverse events systematically and has provided active feedback to the manufacturers and education on safe use. Recently, the Medical Device Safety Information Monitoring Center contributed to harmonization of international medical device vigilance through the sharing of adverse events. This experience of Korea might contribute to improvements in medical device vigilance, which is a critical prerequisite for improving medical device policies and regulations.
