Do neighbourhood environmental perceptions affect practices?

In this paper, we examine how environmental practices related to public transit and urban green space use are influenced by perceptions of local level environmental change, neighbourhood inhabitation, and socio-demographic factors. The analysis shows that perceptions of change and neighbourhood inhabitation offer better explanations for changing local environmental practices than socio-demographic orientations. We contribute to social practice theory by drawing attention to the interplay of environmental perceptions and neighbourhood inhabitation as factors that facilitate changing environmental practices. By gaining insight into the relationship between perceptions of change and environmental practices, we thereby learn how sustainability goals, such as those embodied by SDG11, can be translated into social practices at the community level.Dans cet article, nous examinons comment les pratiques environnementales liées au transport en commun et à l’utilisation des espaces verts urbains sont influencées par les perceptions du changement environnemental au niveau local, l’habitation des quartiers et les facteurs sociodémographiques. L’analyse montre que les perceptions du changement et de l’habitat du quartier offrent de meilleures explications pour l’évolution des pratiques environnementales locales que les orientations sociodémographiques. Nous contribuons è la théorie de la pratique sociale en attirant l’attention sur l’interaction des perceptions environnementales et de l’habitation du quartier en tant que facteurs qui facilitent l’évolution des pratiques environnementales. En acquérant un aperçu de la relation entre les perceptions du changement et les pratiques environnementales, nous apprenons ainsi comment les objectifs de durabilité, tels que ceux incarnées par ODD (Agenda 2030 du développement durable), peuvent être traduits en pratiques sociales au niveau communautaire

Studies on the Acculturation of Young Refugees in the Educational Domain: A Scoping Review of Research and Methods

Given that children and adolescents constitute a growing and significant share of forced migrants worldwide, assessing the state of research on and the methods used to study the acculturation of this group is both timely and essential. The acculturation of refugee children and adolescents in host countries occurs primarily within educational institutions and through the acquisition of the language of the new host society. This scoping review of peer-reviewed journal articles published between 1987 and 2016 (N = 192 eligible studies) examined the extent to which individual-level factors (e.g., gender, age) and contextual factors (e.g., country of residence) emphasized by acculturation models have been considered in research involving young refugees in the educational domain. In addition, the research designs and methods applied in these studies were evaluated, and content analysis was performed to examine whether individual-level factors considered in the sample of studies were related to educational outcomes of young refugees. Overall, the review revealed that very few studies provided adequate information on sample composition, or considered individual and contextual factors, thus leaving crucial gaps in the knowledge about the acculturation of young refugees. Guidelines for future research are proposed to remedy the identified research deficits

The AGN Luminosity Fraction in Merging Galaxies

Galaxy mergers are key events in galaxy evolution, often causing massive starbursts and fueling active galactic nuclei (AGN). In these highly dynamic systems, it is not yet precisely known how much starbursts and AGN respectively contribute to the total luminosity, at what interaction stages they occur, and how long they persist. Here we estimate the fraction of the bolometric infrared (IR) luminosity that can be attributed to AGN by measuring and modeling the full ultraviolet to far-infrared spectral energy distributions (SEDs) in up to 33 broad bands for 24 merging galaxies with the Code for Investigating Galaxy Emission. In addition to a sample of 12 confirmed AGN in late-stage mergers, found in the $Infrared$ $Array$ $Satellite$ Revised Bright Galaxy Sample or Faint Source Catalog, our sample includes a comparison sample of 12 galaxy mergers from the $Spitzer$ Interacting Galaxies Survey, mostly early-stage. We perform identical SED modeling of simulated mergers to validate our methods, and we supplement the SED data with mid-IR spectra of diagnostic lines obtained with $Spitzer$ InfraRed Spectrograph. The estimated AGN contributions to the IR luminosities vary from system to system from 0% up to 91% but are significantly greater in the later-stage, more luminous mergers, consistent with what is known about galaxy evolution and AGN triggering.Comment: 26 pages, 10 figure

Protecting Expert Advice for the Public: Promoting Safety and Improved Communications

The drivers of the harassment and intimidation of researchers are complex, widespread, and global in their reach and were being studied across many disciplines even before COVID-19. This policy briefing reviews some of the scholarship on this wide-ranging problem but focuses on what can be done to help ensure that Canadians fully benefit from the work of Canada’s researchers while also preserving the security and safety of those researchers. It identifies policies and actions that can be implemented in the near term to gather information on the problem, better frame public research communications, and ensure that mechanisms are readily available to support researchers who are threatened. The policy briefing is concerned with researchers, but these behaviours are also harming journalists, politicians, public health communicators, and many others more fully in the public eye than researchers. Some recommendations here may help to address this wider problem

Spatiotemporal EEG Dynamics of Prospective Memory in Ageing and Mild Cognitive Impairment

Prospective memory (PM, the memory of future intentions) is one of the first complaints of those that develop dementia-related disease. Little is known about the neurophysiology of PM in ageing and those with mild cognitive impairment (MCI). By using a novel artificial neural network to investigate the spatial and temporal features of PM related brain activity, new insights can be uncovered. Young adults (n = 30), healthy older adults (n = 39) and older adults with MCI (n = 27) completed a working memory and two PM (perceptual, conceptual) tasks. Time-locked electroencephalographic potentials (ERPs) from 128-electrodes were analysed using a brain-inspired spiking neural network (SNN) architecture. Local and global connectivity from the SNNs was then evaluated. SNNs outperformed other machine learning methods in classification of brain activity between younger, older and older adults with MCI. SNNs trained using PM related brain activity had better classification accuracy than working memory related brain activity. In general, younger adults exhibited greater local cluster connectivity compared to both older adult groups. Older adults with MCI demonstrated decreased global connectivity in response to working memory and perceptual PM tasks but increased connectivity in the conceptual PM models relative to younger and healthy older adults. SNNs can provide a useful method for differentiating between those with and without MCI. Using brain activity related to PM in combination with SNNs may provide a sensitive biomarker for detecting cognitive decline. Cognitively demanding tasks may increase the amount connectivity in older adults with MCI as a means of compensation

Nurse-Midwives’ Knowledge and Promotion of Lactational Amenorrhea and Other Natural Family-Planning Methods for Child Spacing

The purpose of this study was to describe and assess certified nurse-midwives’ (CNMs) knowledge and promotion of two modalities for child spacing, natural family-planning (NFP) and the lactational amenorrhea method (LAM). One thousand two hundred CNMs were randomly selected from a national membership list and mailed a 24-item questionnaire on NFP and LAM. Of the 514 respondents (42.8% return rate), 450 (87.5%) were currently practicing as CNMs. Respondents had an average age of 46 years, with an average of 10 years of practice. CNMs ranked NFP as the ninth most used and the eighth most effective family-planning method in their practice, with an average perceived method-effectiveness of 88% and use-effectiveness of 70%. Although most respondents felt somewhat prepared during their education program to provide NFP, only 22% would offer NFP as a family-planning option for child spacing

A mixed-methods examination of clinicians’ perceived barriers to telehealth delivered applied behavior analysis

Following the COVID-19 pandemic, clinicians relied on telehealth to ensure continuity of essential healthcare services, such as Applied Behavior Analysis (ABA). Identifying barriers and examining them in the context of other implementation outcomes is important to support appropriate adaptations and sustainability of telehealth-delivered ABA services. Convergent mixed methods design was utilized to identify barriers experienced by ABA clinicians (N = 388) when delivering ABA services over telehealth to autistic children and their families following the first six months of the COVID-19 pandemic. Additionally, barriers were examined in relation to telehealth implementation outcomes and intentions for continued adoption. Findings reveal that clinicians rated providing direct services (M = 3.52, SD = 1.14) as more difficult than conducting assessments (M = 3.29, SD = 1.06), and both as more difficult than providing parent-mediated interventions [(M = 2.47, SD = 1.11), F(2, 381) = 162.26, p < 0.001]. A principal components analysis indicated a 3-factor solution of barriers related to: (1) technology (α = 0.82), (2) administrative tasks (α = 0.88), and (3) client characteristics (α = 0.88). The most frequently endorsed barriers were related to client characteristics, including increased difficulty providing telehealth services to children who elope (M = 4.37, SD = 0.81), children who exhibit challenging behaviors (M = 4.31; SD = 0.83), and children who are in the preverbal stage or use nonverbal language to communicate (M = 4.07; SD = 1.00). Fewer barriers related to client characteristics uniquely predicted implementation variables including acceptability, appropriateness, and feasibility. Thematic analysis revealed challenges related to technology, caregiver involvement, child engagement, implementation of intervention strategies over telehealth, and administrative or logistical barriers. These findings highlight the need for targeted strategies that facilitate telehealth use to address specific client needs and support the implementation of telehealth services in usual care settings

The AGN contribution to the UV-FIR luminosities of interacting galaxies and its role in identifying the Main Sequence

Emission from active galactic nuclei (AGNs) is known to play an important role in the evolution of many galaxies including luminous and ultraluminous systems (U/LIRGs), as well as merging systems. However, the extent, duration, and exact effects of its influence are still imperfectly understood. To assess the impact of AGNs on interacting systems, we present a Spectral Energy Distribution (SED) analysis of a sample of 189 nearby galaxies. We gather and systematically re-reduce archival broad-band imaging mosaics from the ultraviolet to the far-infrared using data from GALEX, SDSS, 2MASS, IRAS, WISE, Spitzer and Herschel. We use spectroscopy from Spitzer/IRS to obtain fluxes from fine-structure lines that trace star formation and AGN activity. Utilizing the SED modelling and fitting tool CIGALE, we derive the physical conditions of the ISM, both in star-forming regions and in nuclear regions dominated by the AGN in these galaxies. We investigate how the star formation rates (SFRs) and the fractional AGN contributions ($f_{\rm{AGN}}$) depend on stellar mass, galaxy type, and merger stage. We find that luminous galaxies more massive than about $10^{10} \rm{M}_{*}$ are likely to deviate significantly from the conventional galaxy main-sequence relation. Interestingly, infrared AGN luminosity and stellar mass in this set of objects are much tighter than SFR and stellar mass. We find that buried AGNs may occupy a locus between bright starbursts and pure AGNs in the $f_{\rm{AGN}}$-[Ne V]/[Ne II] plane. We identify a modest correlation between $f_{\rm{AGN}}$ and mergers in their later stages.Comment: Accepted for publication in MNRAS; 24 pages, 15 figures, 3 tables (plus appendix
