The state of the Martian climate

60°N was +2.0°C, relative to the 1981–2010 average value (Fig. 5.1). This marks a new high for the record. The average annual surface air temperature (SAT) anomaly for 2016 for land stations north of starting in 1900, and is a significant increase over the previous highest value of +1.2°C, which was observed in 2007, 2011, and 2015. Average global annual temperatures also showed record values in 2015 and 2016. Currently, the Arctic is warming at more than twice the rate of lower latitudes

Integration of the Pleasant Events and Activity Restriction Models: Development and Validation of a “PEAR” Model of Negative Outcomes in Alzheimer's Caregivers

This study examined an activity restriction/pleasurable activities mismatch model for psychosocial and health-related outcomes. A total of 108 spousal caregivers of patients with Alzheimer's Disease (AD) were assessed for their experience of social and recreational activities over the past month as well as their perception of how restricted they were for engaging in social and recreational activities. Participants were divided into three groups based on their reported activities and activity restriction: HPLR=High Pleasant Events+Low Activity Restriction (i.e., reference group; N=28); HPHR/LPLR=Either High Pleasant Events+High Activity Restriction or Low Pleasant Events+Low Activity Restriction (N=43); LPHR=Low Pleasant Events+High Activity Restriction (N=37). We hypothesized that participants reporting low pleasant events combined with high activity restriction (LPHR) would demonstrate greater disturbance relative to other two groups in multiple outcome domains, including: (a) greater mood disturbance, (b) greater use of negative coping factors, (c) reduced use of positive coping strategies, (d) reduced report of psychological resource factors (e.g., personal mastery, self-efficacy), and (e) increased report of subjective health difficulties (e.g., sleep disturbance). Results generally supported our hypotheses, suggesting that assessment of both constructs is important for best predicting quality of well-being in AD caregivers, and potentially for establishing maximal effect in behavior therapy for caregivers

Dating preferences among self-identified gay men of Asian descent in the United States

Little is known about the dating preferences of Asian American gay men. To conceptualize the dating preferences among these men, the impact domains model (IDM) was used to investigate if nativity and/or acculturation might explain dating preferences. Previous studies have pointed out the problematic nature of a racist cultural stereotype that Asian American gay men prefer white partners (Choi, Yep, & Kumekawa, 1998; Han, 2008). The current findings do not support that Asian American gay men prefer white partners. In our sample, 17.1% preferred dating white men and over 20% preferred Asian men. Over 60% had no clear racial/ethnic dating preference. Multivariate analyses indicated that those reporting higher ethnic acculturation (p <.001) and were U.S.-born (p <.01) were more likely to prefer dating Asian men. In contrast, those younger (p <.001) and living on the East Coast (p <.01) were more likely to prefer dating white men. Limitations of the study include a self-report cross-sectional design with purposive recruitment to study HIV/STIs and sexual health rather than dating preferences. Additionally, the data set included only a coastal classification (East vs. West Coast) and an acculturation scale which included cultural identity, language, and competence. The complex effect of nativity and acculturation on dating preference warrants further investigation. The IDM may be useful to guide future studies of partner preference among Asian MSM. Researchers in future studies should pay attention to identifying the key behavioral, social, and affective beliefs that underlie partner preference and examine actual dating practices
