Knowing Place: Examining the Integration of Place-Based Learning in K-12 Formal Education

This study examines place-based education and its potential for engaging students and creating more socially-just learning environments that prepare students to think critically and participate in building a better future for themselves and the communities in which they live. It was initiated to contribute to a growing body of research on how place-based education philosophies and processes contribute to facilitating high-quality learning experiences that are socially and ecologically just, as well as to inform improved teaching practice and policy within our public education institutions in order to ensure that classroom environments, instructional methods, and learning content are reflective of and responsive to the diverse worldviews and experiences of all students. To explore this focus, I used a semi-structured interview format to gain the perspectives of five teacher participants, all residing in Saskatchewan, who use place-based philosophies and methods. I focused on participants’ perspectives of the benefits, processes, barriers, and possibilities for broad incorporation of place-based education in order to determine how place-based learning can be integrated into K-12 formal education. I transcribed interviews verbatim and used inductive coding to organize data into themes. My findings indicate that the teacher participants view place-based education as offering many significant benefits to students, their communities, and themselves, as educators. They believe that, in addition to creating engaging, motivating, and student-centered environments that promote high standards of student growth and learning, place-based education contributes to healthier and more socially and environmentally just classrooms and communities. Despite some barriers associated with facilitating place-based education, such as financial constraints, time limitations, and other institutional norms and structures imposed upon K-12 classrooms, every participant noted a fervent belief in the possibilities and benefits of the broad incorporation of place-based learning within K-12 formal education. They described examples of how place-based education can be taken up in every classroom as a means to engage all students in meaningful learning to an end of healthier students who imagine and work to realize not only their own potential, but also that of the communities in which they live. The results of this study contribute to the body of research on place-based education, much of which focuses on rationales for its implementation, by detailing specific guidelines and processes for its effective facilitation. The results offer practical considerations for educators and education policy-makers who wish to adopt and advocate for place-based education philosophies and praxes

The Engaged Department Initiative: GVSU, GRCC, and Aquinas Join Forces for Place-Based Impact

The Engaged Department Initiative (EDI) is a place-based cross-institutional collaboration located in the Grand Rapids region. Participating organizations include Michigan Campus Compact (MiCC), Grand Valley State University (GVSU), Grand Rapids Community College (GRCC), and Aquinas College (AQ). This innovative ethnographic case study is focused on evaluating how well the initiative completes their goals of increasing faculty knowledge and skills, expanding students’ community engagement, fostering intra- and inter- collaborations between the three institutions of higher education, and enhancing community partnerships. The hopes of this initiative is to make a real difference in the community and to create engaged citizens. By disseminating this research, we aspire to offer recommendations for people interested in spanning boundaries and working on place-based change in their own region

Advancing pediatric lung health in Africa: COVID-19 and beyond

Respiratory illnesses in children are an important cause of morbidity and mortality in Africa where poverty, food insecurity, malnutrition, and human immunodeficiency virus infection are aggravating factors in many countries. These factors, in addition to under resourced health-care infrastructure, remain important barriers to improving child lung health outcomes in Africa. However, despite these challenges, there have been significant recent advancements in understanding the epidemiology, causes, measurement tools, and treatment of childhood respiratory illnesses. In this review, we highlight some advances in childhood pneumonia, tuberculosis, asthma, and other important non-communicable lung diseases common in children. Furthermore, we discuss the role of environmental influences on children’s lung health in Africa and highlight novel methods of measuring lung function in children. Although children contribute a small role in the global epidemiology of COVID-19 pandemic, socioeconomic and health-care delivery disruptions caused by government responses to contain the pandemic have resulted in significant indirect setbacks to child health. We further highlight how the COVID-19 pandemic has impacted areas of pediatric lung health and discuss ways to mitigate effects of COVID-19 in Africa

Urinary eicosanoid metabolites in HIV-infected women with central obesity switching to raltegravir: an analysis from the women, integrase, and fat accumulation trial.

Chronic inflammation is a hallmark of HIV infection. Eicosanoids reflect inflammation, oxidant stress, and vascular health and vary by sex and metabolic parameters. Raltegravir (RAL) is an HIV-1 integrase inhibitor that may have limited metabolic effects. We assessed urinary F2-isoprostanes (F2-IsoPs), prostaglandin E2 (PGE-M), prostacyclin (PGI-M), and thromboxane B2 (TxB2) in HIV-infected women switching to RAL-containing antiretroviral therapy (ART). Thirty-seven women (RAL = 17; PI/NNRTI = 20) with a median age of 43 years and BMI 32 kg/m(2) completed week 24. TxB2 increased in the RAL versus PI/NNRTI arm (+0.09 versus -0.02; P = 0.06). Baseline PGI-M was lower in the RAL arm (P = 0.005); no other between-arm cross-sectional differences were observed. In the PI/NNRTI arm, 24-week visceral adipose tissue change correlated with PGI-M (rho = 0.45; P = 0.04) and TxB2 (rho = 0.44; P = 0.005) changes, with a trend seen for PGE-M (rho = 0.41; P = 0.07). In an adjusted model, age ≥ 50 years (N = 8) was associated with increased PGE-M (P = 0.04). In this randomized trial, a switch to RAL did not significantly affect urinary eicosanoids over 24 weeks. In women continuing PI/NNRTI, increased visceral adipose tissue correlated with increased PGI-M and PGE-M. Older age (≥ 50) was associated with increased PGE-M. Relationships between aging, adiposity, ART, and eicosanoids during HIV-infection require further study

Doodle Health: A Crowdsourcing Game for the Co-design and Testing of Pictographs to Reduce Disparities in Healthcare Communication

Supplementing patient education content with pictographs can improve the comprehension and recall of information, especially patients with low health literacy. Pictograph design and testing, however, are costly and time consuming. We created a Web-based game, Doodle Health, for crowdsourcing the drawing and validation of pictographs. The objective of this pilot study was to test the usability of the game and its appeal to healthcare consumers. The chief purpose of the game is to involve a diverse population in the co-design and evaluation of pictographs. We conducted a community-based focus group to inform the game design. Game designers, health sciences librarians, informatics researchers, clinicians, and community members participated in two Design Box meetings. The results of the meetings were used to create the Doodle Health crowdsourcing game. The game was presented and tested at two public fairs. Initial testing indicates crowdsourcing is a promising approach to pictograph development and testing for relevancy and comprehension. Over 596 drawings were collected and 1,758 guesses were performed to date with 70-90% accuracies, which are satisfactorily high

The role of the international cocoa germplasm database and the international cocoa quarantine centre in information management and distribution of cocoa genetic resources

A range of physiological parameters (canopy light transmission, canopy shape, leaf size, flowering and flushing intensity) were measured from the International Clone Trial, typically over the course of two years. Data were collected from six locations, these being: Brazil, Ecuador, Trinidad, Venezuela, Côte d’Ivoire and Ghana. Canopy shape varied significantly between clones, although it showed little variation between locations. Genotypic variation in leaf size was differentially affected by the growth location; such differences appeared to underlie a genotype by environment interaction in relation to canopy light transmission. Flushing data were recorded at monthly intervals over the course of a year. Within each location, a significant interaction was observed between genotype and time of year, suggesting that some genotypes respond to a greater extent than others to environmental stimuli. A similar interaction was observed for flowering data, where significant correlations were found between flowering intensity and temperature in Brazil and flowering intensity and rainfall in Côte d’Ivoire. The results demonstrate the need for local evaluation of cocoa clones and also suggest that the management practices for particular planting material may need to be fine-tuned to the location in which they are cultivated

Investigating pupillometry to detect emotional regulation difficulties in post-traumatic stress disorder

Objective: Individuals with posttraumatic stress disorder (PTSD) have been found to exhibit emotional regulation difficulties. However, the specific neural mechanisms that underlie these difficulties remain understudied. This study aimed to use pupillometry as an index function of parasympathetic nervous system activation, to investigate the mechanisms underlying emotional regulation difficulties in individuals with PTSD. Method: A total of 87 trauma-exposed mothers (34 with PTSD and 53 non-PTSD controls) completed an eye tracking assessment in which pupillary dilation in response to emotionally valenced stimuli was measured. The participants also completed two self-report measures of emotional regulation, namely the Difficulties in Emotional Regulation Scale and the Emotional Regulations Questionnaire. Linear mixed-effect modelling was used to assess potential group differences. Results: The PTSD group exhibited increased pupillary dilation to positively valenced stimuli compared to the non-PTSD group. However, no significant associations between the self-report measures and pupillary response to emotionally valenced stimuli were found. Conclusion: Increased pupillary dilation in PTSD may reflect impaired parasympathetic nervous system processes. The lack of association of these measures with self-reported emotion regulation may suggest reporting biases. Larger studies with more generalised populations are required to consolidate these preliminary findings.acceptedVersionPeer reviewe

Efficacy of a dialogic book-sharing intervention in a South African birth cohort: a randomized controlled trial

Evidence shows that dialogic book-sharing improves language development in young children in low-middle income countries (LMICs), particularly receptive and expressive language. It is unclear whether this intervention also boosts development of other neurocognitive and socio-emotional domains in children. Using a randomized controlled trial (RCT) nested in the Drakenstein Child Health Study (DCHS), a book-sharing intervention was implemented in caregivers of 3.5-year-old preschool children living in low-income South African communities. 122 Caregivers and their children (mean age 3.5 years) were randomly assigned to an intervention group (n = 61) or waitlist control group (n = 61). A neurocognitive battery determined baseline receptive and expressive language, executive function, theory of mind, and behavior scores. No differences were observed between intervention and control groups on receptive and expressive language, or any of the neurocognitive or socio-emotional measures from baseline (3.5 years) to 4 months post-intervention administration (4 years). The benefits noted in prior literature of book-sharing in infants did not appear to be demonstrated at 4 months post-intervention, in children from 3.5 to 4 years of age. This suggests the importance of early intervention and emphasizes the need for further research on adaptation of book-sharing for older participants in a South African context. retrospectively registered on 03/04/2022 PACTR202204697674974
