Social media platforms bring both benefits and risks which have been documented copiously in extant academic literature. A range of issues related to privacy and trust inhibit the fulsome enjoyment of social media by users. In 2018, several news sources documented that Cambridge Analytica acquired psychographic data for Facebook users and used that data to target ads for the November 2016 US election. Although none of the news reports indicated that Facebook was complicit in this matter, some Facebook users publicly announced they would leave Facebook and encouraged others to do so. Using in-depth interviews with 10 undergraduate and graduate college students aged 18–29 years, this research study explores decisions to stay with or leave Facebook following the Cambridge Analytica case as such decisions intersect with privacy concerns. While all the respondents were concerned about their privacy, many of them believed that participation in social media requires an exchange of personal data for the use of the service. None of the respondents left Facebook permanently because of the Cambridge Analytica incident. But several reported non-use and reduced use prompted by privacy concerns and other social concerns associated with the use of Facebook. Although these research interviews are centered on a very specific event, they are instructive on the various approaches to privacy patterns and trust in social media. Greater transparency, advocacy, and transnational cooperation would be critical interventions to inspire greater trust in social media platforms.

Species' ranges along altitudinal clines are probably influenced by their ability to adapt to a range of abiotic factors. Physical adaptations in response to lower temperatures at higher altitudes often include changes in body size. We investigated the distribution and potential change in body size with altitude of two species of ground wētā, Hemiandrus maculifrons and Hemiandrus pallitarsis in the Moehau Ecological Area on the Coromandel Peninsula, North Island, New Zealand. Over eight nights of searching, 17 adult H. maculifrons and 28 adult H. pallitarsis were found. Hemiandrus maculifrons was the smaller of the two species and was found at higher altitudes compared with H. pallitarsis (91-577 m and 27-207 m, respectively). No ground wētā were caught in baited and unbaited live-catch pitfall traps (40 set at 211-242 m above sea level; 40 at 620-626 m above sea level). Despite what appeared to be a tendency for the size of male H. maculifrons to increase with altitude, we found no evidence of intraspecific variation in body size with altitude although sample sizes were small. Nevertheless, these two species of ground wētā appear well suited to further investigations into aspects associated with factors that influence body size, distributional range shifts and climate change.

Graft-versus-host-disease (GvHD) is despite improvement in transplantation medicine the major cause for morbidity and mortality after allogeneic stem cell transplantation. We describe a patient with chronic cutaneous GvHD who developed massive skin ulcerations after changing the immunosuppressive therapy to a mammalian target of rapamycin (mTOR)-inhibitor.
