La qualité relationnelle dans la famille recomposée : perspectives du parent et de l’enfant

Cette recherche porte sur les facteurs associés à la qualité relationnelle dans la famille recomposée. Elle met en relation l'âge de l'enfant, le genre de son parent biologique, le degré de contact avec le parent non gardien et la situation socio-économique familiale avec deux indicateurs de qualité relationnelle : la perception de la qualité du fonctionnement familial et la satisfaction à l'égard de ce fonctionnement. Le rendement scolaire est aussi considéré en tant que mesure du niveau d'adaptation extrafamiliale de l'enfant. L'échantillon se compose de 45 dyades enfant-parent biologique (17 pères et 28 mères) vivant dans des familles recomposées depuis en moyenne trois ans et huit mois. Aucune des hypothèses n'a trouvé d'appui dans les données issues des perceptions parentales. Deux hypothèses ont été confirmées à partir des perceptions des jeunes : a) les enfants de 9 à 11 ans perçoivent une meilleure qualité relationnelle dans leur famille recomposée que les adolescents de 14 à16 ans; et b) dans leur nouvelle famille, les enfants vivant avec leur mère biologique sont plus satisfaits des relations familiales que ceux qui vivent avec leur père biologique. Les conséquences pour la pratique et pour la recherche sont définies

Mapping historical forest biomass for stock-change assessments at parcel to landscape scales

Understanding historical forest dynamics, specifically changes in forest biomass and carbon stocks, has become critical for assessing current forest climate benefits and projecting future benefits under various policy, regulatory, and stewardship scenarios. Carbon accounting frameworks based exclusively on national forest inventories are limited to broad-scale estimates, but model-based approaches that combine these inventories with remotely sensed data can yield contiguous fine-resolution maps of forest biomass and carbon stocks across landscapes over time. Here we describe a fundamental step in building a map-based stock-change framework: mapping historical forest biomass at fine temporal and spatial resolution (annual, 30m) across all of New York State (USA) from 1990 to 2019, using freely available data and open-source tools. Using Landsat imagery, US Forest Service Forest Inventory and Analysis (FIA) data, and off-the-shelf LiDAR collections we developed three modeling approaches for mapping historical forest aboveground biomass (AGB): training on FIA plot-level AGB estimates (direct), training on LiDAR-derived AGB maps (indirect), and an ensemble averaging predictions from the direct and indirect models. Model prediction surfaces (maps) were tested against FIA estimates at multiple scales. All three approaches produced viable outputs, yet tradeoffs were evident in terms of model complexity, map accuracy, saturation, and fine-scale pattern representation. The resulting map products can help identify where, when, and how forest carbon stocks are changing as a result of both anthropogenic and natural drivers alike. These products can thus serve as inputs to a wide range of applications including stock-change assessments, monitoring reporting and verification frameworks, and prioritizing parcels for protection or enrollment in improved management programs.Comment: Manuscript: 24 pages, 7 figures; Supplements: 12 pages, 5 figures; Submitted to Forest Ecology and Managemen

Religious Identity and the Use of Alcohol and Marijuana in a Sample of Diverse Young Adults

Religious identity and religiosity are associated with a lower risk of alcohol and other substance use among middle and high school students 1-6 . However, less is known about the influence of religion on substance use among diverse young adults (ages 18-25). 1, 7 Methods: The present study compared the rates of binge drinking and marijuana use among religious and non-religious diverse young adults (n=113). Participants were interviewed and asked about their demographic characteristics as well as whether they engaged in binge drinking or marijuana use in the past 30 days. Chi-square tests were used. Results: A significantly greater proportion of non-religious young adults (93%; n=40) used marijuana in the past month as compared to those identifying as religious [74.3%, n=52; x 2 (1, n=113)=6.18, p<.05]. There was no significant difference in the rate of binge drinking among religious (71.4%; n=50) and non-religious (60.5%; n=26) participants. Conclusions: In our sample of diverse young adults, the protective effect of religious identity was more pronounced with respect to marijuana use as compared to binge drinking which may have been due to the legal status of marijuana and other potential moderators including ones related to religiosity.Psychological, Health, and Learning Sciences, Department ofHonors Colleg
