Using data from 331 parents in a Christian faith-based school system in Australia, the research highlights nine predictors of these attitudes, including perceptions of a child's giftedness and the socio-emotional and academic impacts of gifted education. The study emphasizes the importance of understanding parental attitudes to develop effective educational programs and support systems for gifted students.

Students, community and belonging: an investigation of student experience across six European countries

09 Apr 2024  |  tandfonline.com
The study investigates student experiences of community and belonging across six European countries, focusing on how students define their university community in relation to institutional status and student diversity. In England and Ireland, students from prestigious universities like Oxbridge and HEI3 are perceived differently due to socio-economic backgrounds, while in Denmark and Germany, the differentiation is based on university ethos and practical orientations. The research also explores the 'within university' community, noting that diverse student populations can enhance personal development and belonging. However, feelings of anonymity and exclusion are common among non-traditional students, such as mature students or those with disabilities. The study concludes that the importance of community varies by country, influenced by residential models of higher education, the marketisation of education, and national traditions, affecting students' sense of belonging.

Gynostemma pentaphyllum Hydrodistillate and Its Major Component Damulin B Promote Hair Growth-Inducing Properties In Vivo and In Vitro via the Wnt/β-Catenin Pathway in Dermal Papilla Cells

28 Mar 2024  |  MDPI
The study investigates the hair growth-promoting properties of Gynostemma pentaphyllum leaf hydrodistillate (GPHD) and its major component, damulin B, both in vitro and in vivo. GPHD and damulin B were found to induce hair growth through the Wnt/β-catenin pathway via AKT signaling, showing similar efficacy to minoxidil. The research highlights the potential of GPHD as a natural alternative to current FDA-approved treatments for alopecia, which often have significant side effects. The findings suggest that GPHD and damulin B could be promising candidates for the prevention and treatment of hair loss.

Longitudinal Analysis of SARS-CoV-2-Specific Cellular and Humoral Immune Responses and Breakthrough Infection following BNT162b2/BNT162b2/BNT162b2 and ChAdOx1/ChAdOx1/BNT162b2 Vaccination: A Prospective Cohort in Naive Healthcare Workers

19 Oct 2023  |  mdpi.com
A prospective cohort study evaluated immune responses and breakthrough infections in 235 infection-naïve healthcare workers up to 13–15 months after initial vaccination with either BNT162b2 or ChAdOx1, followed by a BNT162b2 booster. The study found peak immune responses one to two months after the second or third dose, with gradual declines over six months. The ChAdOx1 group showed a more rapid decline in antibody levels after peak response compared to the BNT162b2 group. Breakthrough infections displayed higher neutralization activities against Omicron variants, suggesting cross-immunity. The study highlights the importance of understanding diverse immune response patterns for optimized vaccination strategies.

Greater energy efficiency could double China’s economy sustainably – Analysis

21 Jan 2021  |  iea.org
China's commitment to doubling its economy by 2035 and achieving carbon neutrality by 2060 is underpinned by a shift towards greater energy efficiency. The IEA Sustainable Recovery Plan highlights the role of energy efficiency in spurring economic growth, creating jobs, and reducing emissions. China's past investments in energy efficiency have yielded long-term socioeconomic benefits, and the country is the world's largest ESCO market. Despite a recent slowdown in energy intensity reductions and ESCO investment growth, government incentives and private sector engagement, such as venture capital funding and green bonds, are poised to boost investment and innovation in energy efficiency. Standards for defining and monitoring energy efficiency projects are improving, and with rapid urbanization, energy efficiency remains critical for smart city development.

Social Skill Outcomes Following Physical Activity–Based Interventions for Individuals on the Autism Spectrum: A Scoping Review Spanning Young Childhood Through Young Adulthood

06 Dec 2020  |  journals.humankinetics.com
Physical activity settings may enhance social interaction opportunities for individuals on the autism spectrum, but there is no consensus on the necessary type or amount of physical activity. This scoping review of 25 articles found significant variability in the types of physical activities, social skills, and instruments studied, as well as the intensity of intervention delivery. No longitudinal studies were identified. The findings provide a foundation for designing effective physical activity-based interventions to improve social skills in individuals on the autism spectrum, with a recommendation for future research to employ longitudinal designs.

Why the most successful students have no passion for school

27 Jul 2020  |  Big Think
Research indicates that there is no significant relationship between students' academic success and their passion for school. Analysis of the Programme for International Student Assessment (PISA) data shows that students' attitudes towards school do not correlate with their academic performance. Instead, self-belief and individual psychological factors such as self-efficacy and enjoyment of learning play a more critical role. This disconnect between academic success and school attitude raises concerns about students' long-term views on formal institutions. To address this, educational decision-makers should focus on enhancing the school experience to positively influence students' attitudes and beliefs about formal institutions.

Australia should try to keep more international students who are trained in our universities

10 Sep 2019  |  The Conversation
Australia's education system attracts a significant number of international students, particularly in higher-degree programs. However, the country faces challenges in retaining these students post-graduation, risking a loss of talent. The OECD report highlights Australia's reliance on international students and the need for better incentives to retain them, especially in STEM fields. Despite Australia's strong investment in education and high rates of tertiary education, the financial returns for higher education are lower compared to other OECD countries. The article suggests that Australia should focus on retaining foreign-born graduates to benefit from their skills and contributions.

Why the most successful students have no passion for school

01 Apr 2017  |  Business Insider
Research indicates no significant relationship between students' academic success and their attitudes towards school. Data from the Programme for International Student Assessment (PISA) shows that students' self-belief in their problem-solving abilities is a more critical factor in academic achievement than their perception of school. This disconnect raises concerns about the long-term impact of school experiences on students' views of formal institutions. To address this, educational decision-makers should focus on enhancing the relevance of schooling through hands-on activities that link present education to future life skills.

Whether or not you’ll be successful in school comes down to one surprising factor

13 Mar 2017  |  qz.com
Research indicates that academic success is not linked to students' passion for school but rather to their self-belief in their problem-solving abilities. Analysis of the PISA dataset shows no significant correlation between students' attitudes toward school and their academic performance. The findings suggest that individual psychological factors such as self-efficacy and enjoyment of learning play a more crucial role. The article argues for the importance of improving students' attitudes toward school to foster positive views of formal institutions in the long term.
