Effects of a dog activity tracker on owners' walking: a community-based randomised controlled trial.

A promising strategy to increase population physical activity is through promotion of dog walking. Informed by multi-process action control and nascent dog-walking theory, we examined the effectiveness of a 3-month technology-based (dog tracker) 2-arm randomised controlled dog-walking intervention to increase dog-owner daily physical activity in the general community in Sydney, Australia. 37 participants were allocated to the intervention group (mean age = 43.2 [SD 11.9]) and 40 to the control group (mean age = 42.3 [SD 11.9]). Both groups averaged more than 10,500 steps/day at baseline. There was no evidence of within- or between-group physical activity differences across timepoints. The results remained consistent after exclusion of participants who had data collected during COVID-19 lockdowns. Compared with baseline, both groups had significant increases in sedentary time during the post-intervention, and 6 month follow-up. The absence of significant differences between-group physical activity differences may be attributable to the ceiling effect of both groups already being sufficiently active. These results provide useful guidance to future studies intended to assess the efficacy of technology-based dog-walking interventions. Future dog-walking interventions should specifically target physically inactive dog owners. ACTRN12619001391167 (10/10/2019); Retrospectively registered.

The association between the type of offline social participation and digital literacy among Korean older adults: a cross-sectional study.

Poor social connections are associated with poor digital literacy. Poor digital literacy could induce poor outcomes in daily life or health status, especially among older adults. This study aimed to investigate the effect of social participation based on its absolute magnitude on digital literacy and to confirm the well-known fact that social participations are good for digital literacy is applicable regardless of activity types in a sample of older Korean adults. A total of 9,297 adults aged 65 years or older from the 2020 National Survey of Older Koreans were analyzed. All data were self-reported. Poor digital literacy was defined by limited usage of digital devices. Offline social participation was evaluated using seven different social activities: senior community activities, learning activities, religious activities, volunteer work, leisure, political groups, and club activities. Multivariable logistic regression analysis with covariate adjustment was used for the analysis. Engaging in more than two types of social participation was associated with higher digital literacy: adjusted odds ratio (aOR) 1.965, 95% confidence interval (CI) 1.567-2.465 for two types of participation, and aOR 2.558, 95% CI 2.040-3.208 for more than three types of participation. Additionally, social participation occurring less than once a month and most types of offline activities were associated with improved digital literacy. However, senior community activities were negatively associated with digital literacy (aOR 0.762; 95% CI 0.681-0.852). In this sample of older Korean adults, it was found that the lower the social participation, the poorer the digital literacy. This association may induce the isolation of older adults from societies especially for older adults with senior community activities.

Outcomes of Community-Friendly Schools in Hong Kong

Amid growing competition and evolving demands, schools must rethink their roles in addressing the needs of various stakeholders. Community-friendly schools in Hong Kong, which integrate community resources to help students understand and contribute to social issues, not only facilitate students’ engagement in learning activities and their learning attitudes but also positively impact students’ willingness to serve the community and the school’s reputation. This research adopted both qualitative and quantitative methods, utilizing questionnaires and interviews as data-gathering instruments. The sample included students, teachers, and community stakeholders for the questionnaires, while interviews were conducted with a smaller group, consisting of participants from each of these groups. The performance of these schools was assessed in terms of their impact on students' understanding of the community, willingness to serve, and school reputation. These aspects were evaluated through three tiers of community-friendly schools: community learning activities, activities in cooperation with community organizations, and community services organized by the school. The data analysis employed descriptive statistics, analysis of variance, and linear regression models to highlight the significant impacts of these institutions. Key findings revealed that community-friendly schools significantly boosted student engagement in community activities, deepening their understanding of social issues and fostering a stronger sense of civic responsibility. Students' involvement in these programs was strongly linked to a deeper understanding of the community and a greater willingness to serve. These initiatives also positively impacted the school's reputation, as stakeholders perceived these schools as fostering meaningful community connections and shared responsibility.

Assessing the Long-term Adverse Effects of Aluminium Nanoparticles on Freshwater Phytoplankton Using Isolated-species and Microalgal Communities.

The physicochemical properties of aluminum oxide nanoparticles (Al2O3-NPs or AlNPs) allow them to remain suspended in water for extended periods. Despite this, AlNPs are one of the least studied types of metal nanoparticles and pose a significant risk to aquatic ecosystems. Therefore, it is essential to understand the toxic mechanisms of AlNPs on microalgae and cyanobacteria, as they can have adverse effects on the entire aquatic food web. Our research aimed to assess the toxicity of continuous exposure to low environmentally relevant concentrations of AlNPs on the growth rate, photosynthetic activity, oxidative stress (ROS), and microcystin production (MC-LR) in a phytoplanktonic community (PCC) consisting of Scenedesmus armatus and Microcystis aeruginosa. Both single and community cultures were exposed to 1.0 μg mL-1 AlNPs for 28 days. The results showed a significant 20-40% inhibition of S. armatus population growth in both individual and community cultures after 28 days of exposure. In contrast, M. aeruginosa exhibited increased survival and cell division rates when exposed to nanoparticles, both individually and within the community. Additionally, S. armatus showed a substantial reduction in gross photosynthesis (Pg) and net photosynthesis (Pn), with less inhibition in respiration (R) after 28 days of exposure. Conversely, M. aeruginosa demonstrated higher rates of photosynthetic productivity in all three parameters (Pg, Pn, and R). In the PCC, respiration was inhibited from 14 to 28 days, and both Pg and Pn were also inhibited. Both S. armatus and M. aeruginosa showed 28-31% levels of ROS generation, while the phytoplanktonic community exhibited no significant ROS production. Moreover, the production and release of MC-LR decreased by 8-38% in M. aeruginosa compared to the control strain. These findings underscore the importance of monitoring the use and application of nanomaterials to mitigate their potential toxic effects on aquatic ecosystems.

Diversity pattern and antibiotic activity of microbial communities inhabiting a karst cave from Costa Rica.

The studies of cave bacterial communities worldwide have revealed their potential to produce antibiotic molecules. In Costa Rica, ~400 caves have been identified; however, their microbial diversity and biotechnological potential remain unexplored. In this work, we studied the chemical composition and microbial diversity of a Costa Rican cave (known as the Amblipigida cave) located in Puntarenas, Costa Rica. Additionally, through culture-dependent methods, we evaluated the potential of its microbiota to produce antibiotic molecules. Mineralogical and elemental analyses revealed that the Amblipigida cave is primarily composed of calcite. However, small variations in chemical composition were observed as a result of specific conditions, such as light flashes or the input of organic matter. The 16S rRNA gene metabarcoding revealed an extraordinarily high microbial diversity (with an average Shannon index of ~6.5), primarily comprising bacteria from the phyla Pseudomonadota, Actinomycetota, Firmicutes and Acidobacteriota, with the family Pseudomonadaceae being the most abundant. A total of 93 bacteria were isolated, of which 15% exhibited antibiotic activity against at least one Gram-positive or yeast strain and were classified within the genera Lysobacter, Streptomyces, Pseudomonas, Brevundimonas and Bacillus. These findings underscore the highly diverse nature of cave microbiota and their significant biotechnological potential, particularly in the production of antibiotic compounds.

Parental Support in the Education of Their Children with Impairments: In the Case of North Wollo's Primary Schools

This study aimed to explore parental support practices in the education of children with impairments in primary schools in north Wollo, Ethiopia. The study utilized a qualitative research approach and case study design, involving seven parents of children with impairments and four teachers. Data was collected through semi-structured interviews based on a parental involvement framework with six dimensions. Findings revealed that parents of children with impairments were more involved in parenting practices to support their education. However, communication between parents and teachers was limited, and while some parents provided learning support at home, many were unable to do so due to constraints such as lack of time, misconceptions, and inadequate skills. The study also noted that direct parental involvement in decision-making was limited, while indirect participation through parent-student-teacher associations was more substantial. Additionally, the study revealed that parents did not participate in volunteering or community activities to aid their children's education. As a result, the schools should facilitate discussions and provide training to empower parents in fulfilling their diverse roles.

Analysis of Islamic Legal Anthropology on The Marriage Traditions of The Mbojo and Samawa Tribes

This research aims to describe the similarities and differences in the traditional marriages of the Mbojo and Samawa tribes, as well as how Islamic legal anthropology analyzes these aspects. The study employs qualitative research through field research methods. A qualitative approach is used to observe and convey information that will produce clear data, based on community activities regarding how they are subjects within the research object. This research also contains comparative elements, which involve comparing two situations, events, and occurrences. In this case, the researcher applies a comparative method to the traditional marriages of the Mbojo tribe (Bima) and the Samawa tribe (Sumbawa). Data collection techniques in this study are obtained through direct observation in the field and interviews. Additionally, the data used in this research is supported by literature sources such as books, theses, journals, internet media, and others that support the research. The results of this study indicate that one of the purposes of marriage is to create a family that is peaceful, secure, and harmonious, in line with the concept of sakinah mawaddah wa rahmah. Marriage is a sacred bond between a man and a woman. In anthropology, culture is a system of ideas, actions, and human works that encompass beliefs, arts, morals, laws, and customs. In Indonesia, each region has its own unique culture, including in wedding ceremonies, such as those of the Mbojo tribe in Bima and the Samawa tribe in Sumbawa. Although they have different names and processes, the traditions of peta kapanca and barodak rapacar share the same purpose: to purify oneself in order to achieve a good and harmonious household.

Differences in Physical Activity and Self-Rated Health Levels Based on Satisfaction with Physical Environment of Local Communities: From School to Lifelong Physical Education

Background: In Korea, substantial disparities exist in physical environments across regions, exacerbating the polarization between metropolitan and provincial areas and urban and rural regions. Objectives: This study examines the differences in the physical activity and self-rated health of local communities in relation to satisfaction with the physical environment. By identifying and addressing these underlying causes of health disparities, the study provides foundational data to inform policy efforts. Methods: The study utilized data from the 2023 Community Health Survey conducted by the Korea Disease Control and Prevention Agency. It included 231,752 individuals aged 19 and older (105,754 men and 125,998 women) selected through a two-stage probability proportional systematic sampling method. One-on-one online interviews were conducted from 16 May to 31 July 2023. The physical environment was assessed based on public satisfaction with safety, natural and living environments, public transportation, and medical services. Study variables included subjective health status and physical activity, with subvariables for physical activity encompassing the duration of vigorous and moderate physical activity, walking, and flexibility exercises. For data analysis, MANOVA and ANOVA were conducted, with Bonferroni correction for multiple comparisons. Results: Considerable variations in physical activity were observed based on satisfaction with the local community environment. Regarding self-rated health, significant differences were found in safety levels, living environment, and medical services. Satisfaction with the physical environment positively influenced physical activity and self-rated health. Conclusion: Therefore, it is imperative to reduce disparities in the physical environment between regions and enhance residents’ satisfaction.

A statewide system for maternal-infant linked longitudinal surveillance: Indiana's model for improving maternal and child health

Indiana, located in the Midwest region of the United States, faces significant challenges with respect to health, especially maternal and child health (MCH). These challenges include high rates of stillbirth, neonatal abstinence syndrome (NAS) and congenital syphilis (CS). Not only are these often-fatal conditions underreported, but it can also be difficult to track them longitudinally, as mothers and infants are not routinely linked through electronic health records (EHRs). This paper describes the process, structure and planned outcomes of a partnership between Indiana University, Regenstrief Institute and public health partners in support of the U.S. Centers for Disease Control and Prevention's Pregnant People-Infant Linked Longitudinal Surveillance (PILLARS) program. Together, academic, clinical and public health organisations are collaboratively developing an infrastructure and deploying novel methods to surveil stillbirth, CS and NAS longitudinally. The infrastructure includes: (a) deploying deterministic and probabilistic algorithms to link mothers and their infants using multiple, linked data sources; (b) creating and maintaining a registry of maternal-infant dyads; (c) using the registry to perform longitudinal surveillance in collaboration with Indiana public health authorities on stillbirth, NAS and CS and (d) translating information from surveillance activities into action by collaborating with public health and community-based organisations to improve and implement prevention activities in vulnerable Indiana communities. Our long-term goal is to improve outcomes for these conditions and other priority MCH outcomes by expanding our work to additional MCH use cases.

Effects of bulk forms and nanoparticles of zinc and copper oxides on the abundance, nitrogen cycling and enzymatic activities of microbial communities, morphometric parameters and antioxidant status of Hordeum vulgare L.

Uncontrolled use or improper disposal of bulk forms and nanoparticles of heavy metals may lead to their release into the environment. Coastal and floodplain ecosystems are particularly vulnerable, and the effects of metal nanoparticles on Fluvisol and Stagnic Fluvisol are poorly studied. This study aims to examine the effect of heavy metals on the enzymatic activity of the soil, the abundance of culturable microorganisms, growth, and antioxidant status of H. vulgare L. A model experiment was carried out with contamination of Stagnic Fluvisol Humic and Fluvisol with 2200 and 1320 mg kg-1 Zn and Cu, to assess the ecotoxicity of bulk forms and nanoparticles of ZnO and CuO in floodplain soils. The abundance of culturable microorganisms, namely copiotrophs, prototrophs, oligotrophs and nitrogen fixers increased. However, a sharp decrease in dehydrogenase activity and denitrification occurred. This effect was more pronounced in Fluvisol (7 times) than in Stagnic Fluvisol Humic (3 times). The accumulation of HMs was also higher in plants grown in Fluvisol (16-32 times) than in Stagnic Fluvisol Humic (13-24 times), which led to a decrease in plant growth and activation of antioxidant defense systems. An increase in the level of malondialdehyde, and the activity of superoxide dismutase and catalase indicates the induction of oxidative stress. Heavy metals have a greater impact on the biological properties of Fluvisol compared to Stagnic Fluvisol Humic. The presence of heavy metals boosts the abundance of culturable microorganisms, while nanoparticles hinder plant growth more than bulk heavy metals.

‘People of the barracks’: Meta-beliefs of a migrant community in West Kalimantan, Indonesia

Literature discussing contents of meta-beliefs, or beliefs about other beliefs, and what effects they have on intergroup relationships, specifically among disadvantaged groups are rare. Our study aims to explore meta-beliefs among the resettled Sambas Madurese community, in West Kalimantan, Indonesia, who were affected by the 1999 Sambas Conflict. We adopted an ethnographic approach, with a three-month live-in duration, conducting interviews, casual conversations, and taking part in community activities. Our findings reveal two important contents of meta-belief held by the Sambas Madurese migrants: ‘people of the barracks’, and ‘evil and criminal’. As a disadvantaged group, the Sambas Madurese resort to more covert and subtle forms of resistance, mainly through reappropriation and daily life changes to disprove meta-beliefs. Here, reappropriation of those negative meta-beliefs, mainly linked to moral superiority, is employed. It is observed that the contents of meta-belief go beyond cognitive aspects, including strong emotive components and behavioral responses. Our study hopes to contribute to a discussion on intergroup relationships among host and disadvantaged migrant communities from ethnic conflict backgrounds.

Association of laughter and social communication with oral frailty among residents in Fukushima: a cross-sectional study.

Oral frailty (OF) is a form of frailty. Laughter and social communication such as talking and participating in community activities, contribute to extending healthy life expectancy by reducing stress and increasing physical activity. However, limited research exists on the association between laughter and social communication and OF. This cross-sectional study aimed to explore the association of laughter and social communication with the risk of developing OF using the eight-item OF Index among Fukushima residents. In 2020-2021, 916 residents aged 60-79 were surveyed regarding OF and psychosocial factors. Binomial logistic regression analysis was performed to calculate odds ratios (ORs) and 95% confidence intervals (CIs) for psychosocial factors associated with the OF prevalence. The OF prevalence was 41.5%. The sex- and age-adjusted ORs (95% CIs) for psychosocial factors associated with OF prevalence were 0.38 (0.26-0.57) for daily laughter, 0.51 (0.35-0.76) for laughter 1-5 times/week, 0.42 (0.20-0.89) for daily talking, 0.40 (0.22-0.72) for participating in community activities more than once/week, and 0.29 (0.20-0.43) for no depressive symptoms. After multivariate adjustment, only daily laughter and no depressive symptoms were associated with OF. As a public health strategy, increasing laughter and social communication frequencies, along with reducing depressive symptoms, may enhance healthy life expectancy through improved frailty.

The effect of a low-load plyometric intervention on running kinematics in youth with cerebral palsy: A randomised controlled trial

BackgroundFor children and adolescents with cerebral palsy (CP) who are independently ambulant (Gross Motor Function Classification System (GMFCS) I or II), running is a fundamental movement skill that enables them to play and engage in school and community activities. A running intervention which resulted in good running goal attainment should logically have improved running kinematics, however, this has not yet been established. Research questionDoes a low-load plyometric running intervention improve joint kinematics during running in children with CP? MethodsThree-dimensional gait analysis was undertaken before and after a 12-week intervention. The Gait Profile Score (GPS) was calculated, and linear mixed models were developed. Results36 children with cerebral palsy (control group: male=10, female=8, GMFCS I=12, GMFCS II=6, mean age=12.7 years; intervention group: male=13, female=5, GMFCS I=12, GMFCS II=6, mean age=12.7 years) were included in this study. No significant between-group differences in GPS were found at follow-up. The GPS increased (i.e. running kinematics became more atypical) as speed increased. SignificanceA low-load plyometric intervention which resulted in significant goal attainment in children with CP had no overall effect on running kinematics as measured by the GPS. Future studies should be powered according to both GMFCS level and distribution (unilateral vs bilateral CP).

Spontaneous social media: An exploratory study of young adults’ BeReal uses and gratifications

ABSTRACT Spontaneous social media like BeReal encourage users to post quickly after receiving notifications, leaving little time for planning. However, there has been limited research on why people choose to adopt or avoid spontaneous social media. The current Uses and Gratifications (U&G) framed qualitative study sought to understand why college attending young adults (n = 143) in the United States used or did not use BeReal. Participants completed an online survey with open-ended items, and some (n = 8) additionally completed in-depth interviews. Three themes were constructed through conventional qualitative content analysis: (a) the pursuit of authenticity, (b) audience captivation, and (c) social connection. Participants reported that their coolness, novel, realism, community, authentic gatekeeping, community building, and play/fun needs were gratified using BeReal. Some nonusers were unaware of BeReal. Nonusers and past users reported that the app did not meet their community building, play/fun, activity, or choice needs.

Identification of sport talents through leisure activity: a pathway for achieving football commercialization

ABSTRACT The study identifies how the sport talents of young people are identified through leisure activity, which supports them to achieve professional status. Through recreational specialization and network support, we understand how amateur athletes’ leisure participation evolved through realizing their professional sports dreams. Leisure and recreational specialization studies contribute to explaining players’ progression from their street football activity in communities. Semi-structured interviews and interactions with 19 former African professional players reveal that they relied mostly on networks of recreational intermediaries (e.g. agents, scouts) to reach their recreational specialization, offering them professional sports careers abroad. Former players experienced some challenges through their involvement in leisure behaviour as they sought to commercialize their leisure activity of football for socioeconomic benefit. This paper presents valued evidence for recreational managers or recreational intermediaries to support children’s leisure pursuits in identifying their talents and prospects for development to enhance their livelihood and well-being in the future.

Emotional Health Assessment in Students With Intellectual and Developmental Disabilities.

Students with intellectual and developmental disabilities (IDD) are likely to experience psychiatric symptoms, like depression, anxiety, and distress, throughout their lifetime. Due to communication differences and minimal use of specialized diagnostic assessments for anxiety and depression, emotional pain can often be overlooked or underestimated in students with IDD. This is often complicated by atypical presentations of anxiety and depression, such as externalized aggression, self-injurious behaviors, or other behavioral dysregulation, that can indicate emotional distress, physical pain, or other medical complications. School nurses play an important role in assessing for emotional and physical pain in students with IDD using assessment tools currently available and clinical judgment. Tools that have been created for use in this population may account for the diversity of communication, sensory, and developmental differences in students with IDD. Through leading education and advocacy for the interprofessional school team, school nurses can increase the access that students with IDD have to equitable emotional health evaluations and services. School nurses can also promote emotional wellness for students with IDD through the incorporation of mindful and community activities in the care plan.

Efficiency And Effectiveness Of Circuit Arrangement And Placement Of Thermoelectric For The Design Of Utilizing Zinc Roof As An Electrical Source

<p>The problem related to electrical power sources commonly encountered in society is the frequent occurrence of rotating power outages or sudden blackouts, which disrupt activities for both communities and industries as they heavily rely on electrical power to meet their needs, both collectively and individually. In order to meet the needs of society and industry, Indonesia requires a sufficiently large energy supply. One renewable energy source that can be utilized is solar energy due to its easy availability, cleanliness, and cost-effectiveness. In this study, an experimental method is employed, which utilizes the heat from zinc roofs and converts it into electrical energy using thermoelectric generators. Testing is conducted by varying the circuit arrangements, including series, parallel, and combined configurations, as well as the number of thermoelectric modules (20, 30, and 42 modules), and placement locations on zinc roofs and house ceilings, to observe the output results in terms of voltage and electrical current. As observed from the test results presented in the graphs, the output voltage and current vary for each type of circuit. Based on the use of various circuit arrangements, it can be concluded that combining thermoelectric generators results in higher current and voltage values. The greater the number of thermoelectric modules, the larger the output value. There is a difference in output values between placement on zinc roofs and ceilings, with higher output values observed when installed on zinc roofs. This is due to direct contact between the hot side of the thermoelectric generator and the inner part of the zinc roof. All data obtained from these variations depend on the temperature difference between the hot and cold sides of the thermoelectric generator. The greater the temperature difference produced, the larger the voltage and current output from the circuit. This temperature difference affects the overall performance of the circuit.</p>
