Correlates of Physical Activity in a Cypriot Sample of Sixth-Grade Children

This study examined the association between self-reported physical activity and a number of potential correlates in a sample of 256 Grade 6 children. Physical activity was assessed in both summer and winter, and children and parents completed questionnaires assessing potential correlates of physical activity. Analyses revealed that gender, time spent playing outside, self-efficacy in overcoming barriers, and number of items of exercise equipment at home were variables associated with physical activity in both seasons. School location was a variable associated with physical activity only in the summer, whereas private-lesson attendance, sports-club attendance, and best friend's physical activity were variables associated with physical activity only in winter. Variance explained in physical activity were 42% and 51% in winter and summer, respectively

Peer-education as a tool to educate on antibiotics, resistance and use in 16–18-year-olds: A feasibility study

© 2020 by the authors. Licensee MDPI, Basel, Switzerland. Peer education (PE) interventions may help improve knowledge and appropriate use of antibiotics in young adults. In this feasibility study, health-care students were trained to educate 16–18 years old biology students, who then educated their non-biology peers, using e-Bug antibiotic lessons. Knowledge was assessed by questionnaires, and antibiotic use by questionnaire, SMS messaging and GP record searches. Five of 17 schools approached participated (3 PE and 2 control (usual lessons)). 59% (10/17) of university students and 28% (15/54) of biology students volunteered as peer-educators. PE was well-received; 30% (38/127) intervention students and 55% (66/120) control students completed all questionnaires. Antibiotic use from GP medical records (54/136, 40% of students’ data available), student SMS (69/136, 51% replied) and questionnaire (109/136, 80% completed) data showed good agreement between GP and SMS (kappa = 0.72), but poor agreement between GP and questionnaires (kappa = 0.06). Median knowledge scores were higher post-intervention, with greater improvement for non-biology students. Delivering and evaluating e-Bug PE is feasible with supportive school staff. Single tiered PE by university students may be easier to regulate and manage due to time constraints on school students. SMS collection of antibiotic data is easier and has similar accuracy to GP data

Hybrid glasses from strong and fragile metal-organic framework liquids

This is the final version of the article. It first appeared from NPG via http://dx.doi.org/10.1038/ncomms9079Hybrid glasses connect the emerging field of metal-organic frameworks (MOFs) with the glass formation, amorphization and melting processes of these chemically versatile systems. Though inorganic zeolites collapse around the glass transition and melt at higher temperatures, the relationship between amorphization and melting has so far not been investigated. Here we show how heating MOFs of zeolitic topology first results in a low density ?perfect? glass, similar to those formed in ice, silicon and disaccharides. This order?order transition leads to a super-strong liquid of low fragility that dynamically controls collapse, before a subsequent order?disorder transition, which creates a more fragile high-density liquid. After crystallization to a dense phase, which can be remelted, subsequent quenching results in a bulk glass, virtually identical to the high-density phase. We provide evidence that the wide-ranging melting temperatures of zeolitic MOFs are related to their network topologies and opens up the possibility of ?melt-casting? MOF glasses.The authors would like to thank Trinity Hall (TDB); HRH Sheikh Saud Bin Saqr Al Qasimi (TDB and AKC); Wuhan University of Science and Technology (YY and GNG), ERC grant number 259619 PHOTO EM (CD); Alexander von Humboldt Foundation (SH); The World Premier International Research Center Initiative on Materials Nanoarchitectronics (WPI-MANA) from MEXT, Japan (HHMY)

Going for GOLD! Greater Manchester Growing Older with Learning Disabilities: An inclusive research project to reduce social isolation amongst older adults with learning disabilities

This research was part of the Greater Manchester Growing Older with Learning Disabilities (GM GOLD) project, which was carried out by a team of 16 older people with learning disabilities. The aim was to reduce social isolation amongst older adults (aged 50+) with learning disabilities and to find out what makes somewhere an age-friendly place to live for older adults with learning disabilities. The team was supported by 'research buddies' from Manchester Metropolitan University and the partner organisations to conduct interviews and focus groups with 59 older people (aged 50-79 years) with learning disabilities from eight Greater Manchester areas (Bolton, Bury, Manchester, Oldham, Rochdale, Salford, Tameside, Wigan). Later life transitions for people with learning disabilities are particularly disruptive, and they are at particular risk of social isolation and loneliness. People with learning disabilities have the same rights to relationships and to participate in the cultural life of the community as the rest of society. If society, neighbourhoods and communities do not become more inclusive of people with learning disabilities, in addition to the legal, moral and ethical implications, this is likely to result in additional demand for public services

Melt-Quenched Glasses of Metal–Organic Frameworks

Crystalline solids dominate the field of metal-organic frameworks (MOFs), with access to the liquid and glass states of matter usually prohibited by relatively low temperatures of thermal decomposition. In this work, we give due consideration to framework chemistry and topology to expand the phenomenon of the melting of 3D MOFs, linking crystal chemistry to framework melting temperature and kinetic fragility of the glass-forming liquids. Here we show that melting temperatures can be lowered by altering the chemistry of the crystalline MOF state, which provides a route to facilitate the melting of other MOFs. The glasses formed upon vitrification are chemically and structurally distinct from the three other existing categories of melt-quenched glasses (inorganic nonmetallic, organic, and metallic), and retain the basic metal-ligand connectivity of crystalline MOFs, which connects their mechanical properties to their starting chemical composition. The transfer of functionality from crystal to glass points toward new routes to tunable, functional hybrid glasses.T.D.B. would like to thank Trinity Hall (University of Cambridge) for funding.
