This article attempts to further develop the positionality of place through aggregated effects of vision construction by different positioned actants. We attempt to integrate two concepts: the feminist positionality that stresses the subjects' situatedness in networks and their relational power of vision constructions in host places and the networking behavior of brokers with their exclusive connections to small world clusters, as argued by international relations network analysis. Our attempts at the bodily level of situated and subjective vision construction aim to address two challenges: first, how to address the entanglement of geopolitics and biopolitics, and second, how do encounters account for the power of a place premised on its areal resources through the behavior of brokers. The institutionalization of special economic zone development in Cambodia, from the introduction of new norms to law-making and planning, is chosen as a case for its dynamic process.

Informed by the social ecological model, which asserts that health behaviors and beliefs are the result of multiple levels of influence, we examined factors related to parents' support for in-school COVID-19 mitigation strategies. Using data from a survey of 567 parents/caregivers of public elementary and middle school students in eight Maryland counties, we employed regression models to examine relationships between parent-, child-, family-, school-, and community-level factors and acceptability of mitigation strategies. Acceptance of COVID-19 mitigation strategies was positively correlated with child- and family-level factors, including child racial identity (parents of Black children were more accepting than those of White children, odds ratio [ OR ]: 2.5, 95% confidence interval [CI] = [1.5, 4.1]), parent receipt of the COVID-19 vaccine (OR : 2.4, 95% CI = [1.5, 3.7]), and parent Democrat or Independent political affiliation (compared with Republican affiliation, OR : 4.2, 95% CI = [2.6, 6.7]; OR : 2.2, 95%CI = [1.3, 3.8], respectively). Acceptance was also positively associated with parents' perceptions of their school's mitigation approach, including higher school mitigation score, indicating more intensive mitigation policies (OR : 1.1, 95% CI = [1.0, 1.1]), better school communication about COVID-19 (OR : 1.7, 95% CI = [1.4, 1.9]) and better school capacity to address COVID-19 (OR : 1.9, 95% CI = [1.5, 2.4]). Community-level factors were not associated with acceptance. Child- and parent-level factors identified suggest potential groups for messaging regarding mitigation strategies. School-level factors may play an important role in parents' acceptance of in-school mitigation strategies. Schools' capacity to address public health threats may offer an underappreciated and modifiable setting for disseminating and reinforcing public health guidance. [ABSTRACT FROM AUTHOR]

BACKGROUND: At the onset of the COVID‐19 pandemic, schools closed across the United States. Given the impact of virtual learning and lost access to school resources, schools eventually reopened with COVID‐19 mitigation protocols in place. This qualitative study sought to understand parental perceptions of school‐based COVID‐19 mitigation strategies. METHODS: Using a phenomenology approach, nine focus groups were completed with 40 parents of children in grades K‐8 representing eight Maryland counties. Based on acceptance of masking policies (as indicated on a survey), parents were sorted into 2 groups—lower and higher masking acceptance. A thematic analysis was conducted for each group and themes were compared between the 2 groups. RESULTS: The main themes were related to parents' general sentiments regarding COVID‐19, compliance, pandemic‐related changes over time, changes in personal opinions, and in‐person learning. Both groups described challenges related to inconsistent COVID‐19 mitigation policies and practices, the challenges of rapid and frequent changes in guidelines during the pandemic, and the benefits of in‐person learning. CONCLUSIONS: Parents of elementary and middle school children, regardless of general acceptance of masking policies, shared concerns about implementation and guidance regarding school‐based mitigation strategies.

How to capture, represent, and materialize public interest in urban planning has gone through multiple rounds of experimentation, crystallizing a number of regulatory regimes of planning in different historical and political-economic contexts. However, how to define the "public" and capture the public interest in urban planning remains problematic in both planning practices and democratic theory. Therefore, drawing upon Dewey and Habermas's view of the public sphere, this paper introduces a scale perspective to examine the subjects in planning and the power framing process in defining the public in urban regeneration policymaking. First, this paper revisits the current debates on the concept of public interest and identifies three interpretations of public interest materialization: utilitarian, unitary, and communicative. Second, this paper illustrates the institutionalization process of public interest in China's urban planning system. We critically examine the evolving mechanisms of public representation in China's urban regeneration policymaking since 1949. The institutionalization of public interest in China shows distinguished trajectories from the Western countries. These differences are caused by different values that define the scale of "public" in different socio-political contexts. Given the emerging communicative turn in China, we found a hybrid norm of public interest as reflected in the recent "co-production" model of urban regeneration. The contribution of this paper is threefold: 1) highlights the validity of the public interest concept by introducing a scale sensitivity to analyze the subjects in planning; 2) complements public interest typology by identifying a hybrid norm in China that weaves between unitary and communicative interpretations; 3) revisits Dewey's democratization theory by conceptualizing the institutionalization of public interest in semi-authoritarian China that is determined across the scales of subjects in planning, the ever-changing political-economic contexts, and the planning application in established rules.

As a fruit and vegetable crop, the ornamental pepper is not just highly ornamental but also rich in nutritional value. The quality of ornamental pepper fruits is given in their contents of capsaicin, vitamin C (VC), flavonoids and total phenols. The study concentrated on the accumulation of capsaicin and dihydrocapsaicin in different tissues of 18 peppers during fruit growth and development. The results showed that the pericarp and placenta contained significantly higher levels of capsaicin than dihydrocapsaicin. Additionally, the placenta contained significantly higher levels of both capsaicin and dihydrocapsaicin compared to the pericarp. The content of capsaicin was in the range of 0–6.7915 mg·g−1, the range of dihydrocapsaicin content was 0–5.329 mg·g−1. Interestingly, we found that the pericarp is rich in VC (5.4506 mg·g−1) and the placenta is high in flavonoids (4.8203 mg·g−1) and total phenols (119.63 mg·g−1). The capsaicin is the most important component using the correlation analysis and principal component analysis. The qPCR results substantiated that the expression of genes in the placenta was significantly higher than that in the pericarp and that the expression of genes in green ripening stage was higher than that in red ripening stage. This study could be utilized to select the best ripening stages and tissues to harvest peppers according to the use of the pepper and to the needs of producers. It not only provides a reference for quality improvement and processing for consumers and market but also provides a theoretical basis for high-quality pepper breeding. [ABSTRACT FROM AUTHOR]

Background: Individuals with autism spectrum disorder (ASD) have social communication difficulties and restricted, repetitive, and/or sensory behaviors or interests. The prevalence of ASD is now 1 in 36 individuals. Parents of individuals with ASD face challenges that can affect their physical and psychological well-being. Objective: With the long-term goal to tailor an exercise program, the purpose of this study was 2-fold: (1) establish the baseline physical and mental health of parents of individuals with ASD and (2) estimate the relationship of physiologic variables with psychological variables of health for parents of individuals with ASD. Methods: This descriptive, cross-sectional study (N = 44) explored physical health measures and the correlation between physical and psychological health, using measures of anxiety, stress, parenting depression, and positive thinking for parents who care for individuals with ASD. Results: The common characteristics that these parents shared was high body fat and low physical activity. Body fat was negatively correlated to total step count (r = −0.428, P <.05), grip strength (r = −0.319, P <.5), and total distance walked in the week (r = −0.661, P <.01), and positively correlated to 5-times sit to stand (r = 0.337, P <.05). Low activity correlated to increased parenting stress of advocating for child's needs (r = −0.310, P =.043). Conclusions: Understanding relationships between physical and psychological health informs effective interventions and support systems for parents. Parents need supports to be able to prioritize exercise. Future studies should include a larger sample to verify these effects. [ABSTRACT FROM AUTHOR]

By deconstructing the human–machine interface across China's economic history, this commentary on Luger and Schwarze's paper highlights the critical need to explore gender dynamics in post-industrial cities through the human–machine interface. We suggest two new concepts, subjectivity and deep interface, which may offer a way forward for us to move deeper into post-industrial cities for a more intricate understanding of the enduring inequalities shaping these urban landscapes.

Background and objectives: Transgender and gender diverse (trans) health research has grown rapidly, highlighting the need to characterize the scientific evidence base. We conducted a systematic review of peer-reviewed research on disease burden and correlates in trans adolescents and adults over a 20-month period to identify knowledge gaps and assess methodological characteristics including measurement of gender identity, community engagement, and study quality. Data sources, eligibility criteria, and synthesis methods: We searched seven databases using terms related to (a) transgender populations and (b) health or disease. Eligible studies were in English, French, or Spanish and reported original quantitative data on mental health or substance use conditions, infectious diseases, or non-communicable conditions in at least 25 trans individuals aged 15+. Quality assessment was performed in duplicate on a 10% sample of articles and findings were summarized using narrative synthesis. Results: The 328 included studies were conducted in 45 countries, with most from North America (54%) and limited research from South Asia (3%), Sub-Saharan Africa (3%), and the Middle East and North Africa (2%). Most studies used cross-sectional designs (73%) and convenience sampling (65%). Only 30% of studies reported any form of community engagement. Mental health and substance use disorders were the most studied area (77% of studies) and non-communicable conditions the least (16%). Available data indicated that trans populations experience high disease burden with considerable heterogeneity within and across settings. Of 39 articles assessed for quality, 80% were rated as fair, 18% as poor, and 3% as good quality. Conclusions and implications: Geographic, gender-specific, and topical gaps remain in trans health, but we found more research from African countries, with transmasculine people, and on non-communicable conditions than previous syntheses. Areas for growth in trans health research include community engagement, non-binary health, chronic and age-related conditions, and health determinants. Registration: PROSPERO CRD42021234043.

Background: The aims of this review were to describe exercise interventions, facilitators, and barriers to physical activity for parents of children with autism spectrum disorder. Methods: A systematic review of the literature, appraising the validity of each article with Melnyk and Fineout-Overholt's level of evidence, from different databases CINAHL, Cochrane, PsycINFO, PubMed, ProQuest, and Web of Science between 2000 and 2020 was conducted. As the initial search revealed no articles on exercise interventions and only 2 articles with children with autism spectrum disorder, the aim was widened to all parents of children. Results: Forty-five articles were identified on barriers to physical activity including being the primary caregiving parent, perception of guilt and selfishness, and adhering to exercise programs they do as part of research, once research ends. Facilitators for physical activity including parents being more likely to exercise if they can bring their child with them and parents preferring exercise that is a lifelong habit, such as walking. Conclusions: Due to the lack of research on parents of children with autism spectrum disorder, recommendations include development and testing of interventions for parents of children with this condition including family-based exercise interventions where children and parents have a choice to exercise together.

So far relatively little research in education has explored the pedagogical and learning potentials of applications (Apps) on tablet PCs (TPCs). Drawing upon research on learning technologies and taking an embodied perspective, this study first identified educational functionalities of TPCs and generated guidelines to design educational Apps for science learning. Following the guidelines, two Apps were developed and their effects on students' science learning were examined. A total of 61 11th graders from 3 classes in a public senior high school participated in instructional activities using the Apps. The test results showed a significant improvement in the students' conceptual understanding of the projectile motion and collision of moving objects. The results also suggest that the implementation of the Apps was particularly useful for the students' understanding of advanced concepts. This study could extend current understandings of how mobile technologies support reform-based science teaching and learning.

Field research campaigns in 2019 and 2020 collected hourly atmospheric profiles via radiosonde surrounding the 2 July 2019 and 14 December 2020 total solar eclipses over South America from locations within the paths of eclipse totality. As part of these atmospheric data collection campaigns, the eclipse module of the Advanced Research Weather Research and Forecast (WRF-ARW) model was utilized to model meteorological conditions before, during, and after the eclipse events. The surface and upper-air observational datasets collected through these campaigns have enabled further assessment and validation of the WRF-ARW's eclipse module performance in simulating atmospheric responses to total solar eclipses. We provide descriptions of the field campaigns for both 2019 and 2020 and present results from comparisons of meteorological variables both at the surface and aloft using observational datasets obtained through the campaigns. The paper concludes by recommending further scientific analyses to be explored utilizing the unique datasets presented. [ABSTRACT FROM AUTHOR]

In this study, antagonistic activities and probiotic potential of lactic acid bacteria (LAB) derived from a plant-based fermented food, kimchi, were demonstrated. The cell free supernatants (CFS) from Lactobacillus curvatus KCCM 43119, Leuconostoc mesenteroides KCCM 43060, Weissella cibaria KCTC 3746, and W. koreensis KCCM 41517 completely inhibited the growth of foodborne pathogenic bacteria, while neutralized CFS (pH 6.5) partially inhibited the growth. The competition, exclusion, and displacement of foodborne pathogenic bacteria by the LAB strains from adhesion to HT-29 cells were investigated. The LAB strains were able to compete with, exclude, and displace the foodborne pathogenic bacteria. However, the degree of inhibition due to the adhesion was found to be a LAB strain-dependent phenomenon. The LAB strains showed high coaggregation with foodborne pathogenic bacteria, and they also exhibited high resistance to acidic condition. Except W. cibaria KCTC 3746, all LAB strains were capable of surviving in the presence of bile salts. Furthermore, while all LAB strains were resistant to chloramphenicol, kanamycin, streptomycin, gentamicin, and erythromycin, only W. cibaria KCTC 3746 and W. koreensis KCCM 41517 displayed resistance to vancomycin. These results suggest that the LAB strains derived from kimchi exerted antagonistic activities against foodborne pathogenic bacteria with probiotic potential.
