Mitigation of H2RG persistence with image illumination

Residual charge generation, or image persistence, in infrared detectors is a problem that affects many low-light astronomical instruments. The HAWAII-2RG in the MMT and Magellan Infrared Spectrograph shows significant persistence when first powered up. We describe here how we reduce the persistence sensitivity of this detector by exposure to light

Traditional Ecological Knowledge (TEK) of the Woodlands Cree and Denesuline Peoples of northern Saskatchewan, Canada: The land as teacher and healer

The purpose of this article is to explore and outline the Traditional Ecological Knowledge (TEK) of First Nation peoples in northern Saskatchewan, Canada. TEK and Western science are increasingly combined for a fuller portrait and understanding of the natural world. However, more research is needed using Indigenous protocols, methodologies, methods, and languages for conceptual clarity. For the Woodlands Cree and Denesuline (Dene) peoples, the land is a giver of life and is both a teacher and healer as represented in this article

University Students from Four Ethnopolitical Conflict Zones: An Exploratory Study of Perceptions of Self and Country

This exploratory comparative case study examines hopes and fears for self and country of 300 students attending university in Bosnia-Herzegovina, Northern Ireland, South Africa, and Sri Lanka. Students report living in stressful societies where ethno political and state violence were the norm. The results of this qualitative study indicate that while the young people are optimistic about their life changes, they are concerned that the conflicts could re-ignite and spiral out of control. In particular, the students’ images indicate the importance of the self-society relationship and that these young adults relish the challenge of being productive citizens in their post-conflict societies

On the Rotation Period of (90377) Sedna

We present precise, ~1%, r-band relative photometry of the unusual solar system object (90377) Sedna. Our data consist of 143 data points taken over eight nights in October 2004 and January 2005. The RMS variability over the longest contiguous stretch of five nights of data spanning nine days is only 1.3%. This subset of data alone constrain the amplitude of any long-period variations with period P to be A<1% (P/20 days)^2. Over the course of any given 5-hour segment, the data exhibits significant linear trends not seen in a comparison star of similar magnitude, and in a few cases these segments show clear evidence for curvature at the level of a few millimagnitudes per hour^2. These properties imply that the rotation period of Sedna is O(10 hours), cannot be 10 days, unless the intrinsic light curve has significant and comparable power on multiple timescales, which is unlikely. A sinusoidal fit yields a period of P=(10.273 +/- 0.002) hours and semi-amplitude of A=(1.1 +/- 0.1)%. There are additional acceptable fits with flanking periods separated by ~3 minutes, as well as another class of fits with P ~ 18 hours, although these later fits appear less viable based on visual inspection. Our results indicate that the period of Sedna is likely consistent with typical rotation periods of solar system objects, thus obviating the need for a massive companion to slow its rotation.Comment: 7 pages, 4 figures, 2.5 tables.

A Four-Stage Method for Developing Early Interventions for Alcohol Among Aboriginal Adolescents

This paper details a four-stage methodology for developing early alcohol interventions for at-risk Aboriginal youth. Stage 1 was an integrative approach to Aboriginal education that upholds Aboriginal traditional wisdom supporting respectful relationships to the Creator, to the land and to each other. Stage 2 used quantitative methods to investigate associations between personality risk factors and risky drinking motives. Stage 3 used qualitative interviews to further understand the contexts and circumstances surrounding drinking behaviour within a larger cultural context. Stage 3 involved tailoring personality- matched, motive-specific brief interventions to meet at-risk adolescents’ needs. Stage 4 involved an efficacy test of the interventions. This novel methodology has significance for future program development to meet diverse social, cultural and health needs of at-risk adolescents
