The First Post-Kepler Brightness Dips of KIC 8462852

We present a photometric detection of the first brightness dips of the unique variable star KIC 8462852 since the end of the Kepler space mission in 2013 May. Our regular photometric surveillance started in October 2015, and a sequence of dipping began in 2017 May continuing on through the end of 2017, when the star was no longer visible from Earth. We distinguish four main 1-2.5% dips, named "Elsie," "Celeste," "Skara Brae," and "Angkor", which persist on timescales from several days to weeks. Our main results so far are: (i) there are no apparent changes of the stellar spectrum or polarization during the dips; (ii) the multiband photometry of the dips shows differential reddening favoring non-grey extinction. Therefore, our data are inconsistent with dip models that invoke optically thick material, but rather they are in-line with predictions for an occulter consisting primarily of ordinary dust, where much of the material must be optically thin with a size scale <<1um, and may also be consistent with models invoking variations intrinsic to the stellar photosphere. Notably, our data do not place constraints on the color of the longer-term "secular" dimming, which may be caused by independent processes, or probe different regimes of a single process

Public and private domains of religiosity and adolescent smoking transitions

We used data from a nationally representative sample of US adolescents in school grades 7 through 12 to explore the effects of public and private religiosity on initiation, escalation, and cessation of smoking. We found that adolescents' decisions to experiment with smoking are influenced by both their individual practice of their faith and by participation in a larger faith community. However, the effects of private and public religiosity are specific to different decision points on the smoking uptake process. Private religiosity was protective against initiation of regular smoking among nonsmokers. It also was protective against initiation of experimental smoking but only when the young person frequently attended religious services or a religious youth group. Although private religiosity appeared to discourage the uptake of smoking, it was unrelated to reduction or cessation once a young person has become addicted to cigarettes. In contrast, public religiosity did predict reduction and cessation of cigarette use among regular smokers. Taken together, these findings demonstrate that the domains in which religiosity are important extend beyond the individual and include religious institutions.USA Religiosity Adolescents Smoking uptake Cessation Transitions

Public and private domains of religiosity and adolescent health risk behaviors: evidence from the National Longitudinal Study of Adolescent Health

The purpose of this study was to examine the association of public and private domains of religiosity and adolescent health-related outcomes using data from the National Longitudinal Study of Adolescent Health (Add Health), a nationally representative sample of American adolescents in grades 7-12. The public religiosity variable combines two items measuring frequency of attendance at religious services and frequency of participation in religious youth group activities. The private religiosity variable combines two items measuring frequency of prayer and importance of religion. Our results support previous evidence that religiosity is protective for a number of adolescent health-related outcomes. In general, both public and private religiosity was protective against cigarettes, alcohol, and marijuana use. On closer examination it appeared that private religiosity was more protective against experimental substance use, while public religiosity had a larger association with regular use, and in particular with regular cigarette use. Both public and private religiosity was associated with a lower probability of having ever had sexual intercourse. Only public religiosity had a significant effect on effective birth control at first sexual intercourse and, for females, for having ever been pregnant. However, neither dimension of religiosity was associated with birth control use at first or most recent sex. Public religiosity was associated with lower emotional distress while private religiosity was not. Only private religiosity was significantly associated with a lower probability of having had suicidal thoughts or having attempted suicide. Both public and private religiosity was associated with a lower probability of having engaged in violence in the last year. Our results suggest that further work is warranted to explore the causal mechanisms by which religiosity is protective for adolescents. Needed is both theoretical work that identifies mechanisms that could explain the different patterns of empirical results and surveys that collect data specific to the hypothesized mechanisms.USA Religiosity Adolescents Risk behaviors Substance use Sexual behavior

Mental Suffering in Protracted Political Conflict: Feeling Broken or Destroyed.

PURPOSE:This mixed-methods exploratory study identified and then developed and validated a quantitative measure of a new construct of mental suffering in the occupied Palestinian territory: feeling broken or destroyed. METHODS:Group interviews were conducted in 2011 with 68 Palestinians, most aged 30-40, in the West Bank, East Jerusalem, and the Gaza Strip to discern local definitions of functioning. Interview participants articulated of a type of suffering not captured in existing mental health instruments used in regions of political conflict. In contrast to the specific difficulties measured by depression and PTSD (sleep, appetite, energy, flashbacks, avoidance, etc.), participants elaborated a more existential form of mental suffering: feeling that one's spirit, morale and/or future was broken or destroyed, and emotional and psychological exhaustion. Participants articulated these feelings when describing the rigors of the political and economic contexts in which they live. We wrote survey items to capture these sentiments and administered these items-along with standard survey measures of mental health-to a representative sample of 1,778 32-43 year olds in the occupied Palestinian territory. The same survey questions also were administered to a representative subsample (n = 508) six months earlier, providing repeated measures of the construct. RESULTS:Across samples and time, the feeling broken or destroyed scale: 1) comprised a separate factor in exploratory factor analyses, 2) had high inter-item consistency, 3) was reported by both genders and in all regions, 4) showed discriminate validity via moderate correlations with measures of feelings of depression and trauma-related stress, and 5) was more commonly experienced than either feelings of depression or trauma-related stress. CONCLUSIONS:Feeling broken or destroyed can be reliably measured and distinguished from conventional measures of mental health. Such locally grounded and contextualized measures should be identified and included in assessments of the full impact of protracted political conflict on functioning
