Moving well, being well: an intervention aimed at increasing fundamental movement skills in Irish primary school children, while also increasing teacher confidence in delivering physical activity based lessons.

Physical Activity (PA) has long been positively linked with health benefits. Recent research shows that 67% of adolescents are not getting the recommended one hour of moderate to vigorous activity (MVPA) per day. In addition, 99.5% of the same sample did not achieve the level of Fundamental Movement Skill (FMS) proficiency expected of their age. In young children FMS proficiency is hypothesised to correlate with increased PA in later life, and these skills are best developed throughout the early school going years. To address these alarming statistics, phase one of the Moving Well-Being Well project has assessed a nationwide sample (n=2148) of primary school children (5-13 years) in Ireland. The range of assessments covered all aspects of the currently accepted physical literacy model: competence, motivation, confidence, and knowledge and understanding. The results show that 77.5% of primary school children were classed as ‘very poor’ or ‘below average’ in FMS proficiency (n=2098, Male 53%). The findings also show significantly higher (p<0.001) FMS proficiency for children who achieve high levels of MVPA, over those who are less active. Confidence and motivation both saw significant increases (p<0.05) for those categorised as highly active, compared to those in the low activity group. There was significant difference between these groups for knowledge and understanding, and 54.8% did not know the minimum recommended MVPA guidelines. These findings have been used to develop the intervention aiming at addressing these deficiencies. The intervention targets increasing teacher confidence in delivering FMS programmes through an innovative school’s in-service training program

Getting Ireland’s Children Moving: Examining fundamental movement skills in Irish school children as a key component for physical literacy.

Recent reports from the World Health Organisation predict Ireland to be ‘the most obese nation in Europe by 2030”. In addition to this stark warning, recent research findings suggest that the country’s adolescents are falling short of physical literacy. With physical literacy being recognised as a key driver in lifelong physical activity participation, phase one of the Moving Well-Being Well study has assessed primary school children (5-13 years) in all aspects of the currently accepted physical literacy model. Areas of assessment included; fundamental movement skills (FMS) proficiency, perceived motor skill competence, motivation and confidence measures, health related fitness measures, body image, wellbeing and physical activity participation. FMS proficiency has been associated with beneficial health outcomes, and is most successfully developed during early school years, and as such is a central component of this study. Data was collected nationwide (n=2098, male 53%), and findings show that 77.5% of children scored between ‘very poor’ and ‘below average’ in FMS proficiency. There was no difference between children attending urban and rural schools, but notably, when socioeconomic status is taken into account, the schools in middle and upper-class neighbourhoods scored significantly higher (p<0.001) than those in the so called disadvantaged areas. The results also show significantly higher (p<0.001) FMS proficiency for children who achieve high levels of moderate to vigorous activity (MVPA), over those who are less active. Findings suggest that Irish primary school children fail to exhibit age-appropriate FMS proficiency. This low level of motor skills proficiency can have direct negative implications for future participation in physical activity. These findings are being used to create the structure of the Moving Well-Being Well intervention aiming at addressing these deficiencies

Exploring components of physical literacy in Irish children

Aim: To investigate the relationship between Self-Determination Theory’s motivational regulations and fundament movement skills (FMS) in primary school children. Quality of physical activity (PA) motivation has been found to be an important correlate and a potential determinant of PA. However, there are few that have investigated the quality of PA motivation’s relationship with determinants and correlates of PA, such as fundamental movement skills (FMS). There is an increasing recognition of the relationship between FMS and PA in childhood, with studies beginning to show a causal relationship. Thus, this study investigates the relationship between children’s quality of PA motivation and their FMS proficiency. The motivation and FMS of 865 children (47.7% female, 10.9 ± 1.16 years) was collected. The TGMD-3 (Ulrich, 2017) was implemented to evaluate FMS. Meanwhile, quality of motivation was measured using the BREQ which was adapted for children (Sebire et al., 2013). A hierarchical multiple regression was conducted to assess the capacity of four measures (intrinsic motivation, identified, introjected and external regulations) on FMS proficiency, with separate male and female analysis. The four measures explained 8.9% of the variance in FMS for males (R2 = .089, p < .001) and 5.5% for females (R2 = .055, p < .001). For males, three measures were statistically significant (p < .05): identified (β = .21), external (β = -.14), and introjected (β = .13) regulation. Meanwhile, for females only external regulation (β = -.21) made a significant contribution to FMS. The results of the current research are congruent with previous SDT research, demonstrating how motivation quality influences FMS proficiency. It is no surprise that FMS proficiency and intrinsic motivation do not have a significant relationship; perhaps developing FMS proficiency requires individuals to place value on the skills and to recognise the importance of FMS in terms of facilitating their participation and success in PA. This study provides evidence for the need to promote autonomous motivation and prevent controlling motivation when designing, testing and implementing FMS interventions

Progress and Trends in Artificial Silk Spinning: A Systematic Review

More than 400 million years of natural selection acting throughout the arthropoda has resulted in highly specialized and energetically efficient processes to produce protein-based fibers with properties that are a source of inspiration for all. As a result, for over 80 years researchers have been inspired by natural silk production in their attempts to spin artificial silks. While significant progress has been made, with fibers now regularly outperforming silkworm silks, surpassing the properties of superior silks, such as spider dragline, is still an area of considerable effort. This review provides an overview of the different approaches for artificial silk fiber spinning and compares all published fiber properties to date which has identified future trends and challenges on the road towards replicating high performance silks

Global Analysis of Aerosol Properties Above Clouds

The seasonal and spatial varability of Aerosol Above Cloud (AAC) properties are derived from passive satellite data for the year 2008. A significant amount of aerosols are transported above liquid water clouds on the global scale. For particles in the fine mode (i.e., radius smaller than 0.3 m), including both clear sky and AAC retrievals increases the global mean aerosol optical thickness by 25(+/- 6%). The two main regions with man-made AAC are the tropical Southeast Atlantic, for biomass burning aerosols, and the North Pacific, mainly for pollutants. Man-made AAC are also detected over the Arctic during the spring. Mineral dust particles are detected above clouds within the so-called dust belt region (5-40 N). AAC may cause a warming effect and bias the retrieval of the cloud properties. This study will then help to better quantify the impacts of aerosols on clouds and climate

Tcf7l2 plays pleiotropic roles in the control of glucose homeostasis, pancreas morphology, vascularization and regeneration

Type 2 diabetes (T2D) is a disease characterized by impaired insulin secretion. The Wnt signaling transcription factor Tcf7l2 is to date the T2D-associated gene with the largest effect on disease susceptibility. However, the mechanisms by which TCF7L2 variants affect insulin release from β-cells are not yet fully understood. By taking advantage of a tcf7l2 zebrafish mutant line, we first show that these animals are characterized by hyperglycemia and impaired islet development. Moreover, we demonstrate that the zebrafish tcf7l2 gene is highly expressed in the exocrine pancreas, suggesting potential bystander effects on β-cell growth, differentiation and regeneration. Finally, we describe a peculiar vascular phenotype in tcf7l2 mutant larvae, characterized by significant reduction in the average number and diameter of pancreatic islet capillaries. Overall, the zebrafish Tcf7l2 mutant, characterized by hyperglycemia, pancreatic and vascular defects, and reduced regeneration proves to be a suitable model to study the mechanism of action and the pleiotropic effects of Tcf7l2, the most relevant T2D GWAS hit in human populations. © 2017 The Author(s)

Associations between small ruminant lentivirus infection and total milk yield and somatic cell count in a dairy sheep flock

BackgroundSmall ruminant lentiviruses (SRLVs) are lentiviruses of sheep and goats, formerly known as maedi–visna (MV) in sheep and caprine encephalitis and arthritis in goats. In sheep, SRLVs commonly cause progressive pneumonia, wasting and indurative mastitis. SRLVs have a long latent period, and chronic production losses are often not recognised until very late. Few studies quantifying the production losses in ewes have been published, and none have been published under UK flock husbandry conditions.MethodsProduction records of milk yield and somatic cell count (SCC) from a dairy flock of 319 milking East Friesian × Lacaune ewes identified as MV infected via routine serological screening for SRLV antibodies were used in multivariable linear regression modelling to estimate the impact of SRLV status on total milk yield and SCC.ResultsMilk yield was reduced in seropositive ewes by 8.1%–9.2% over an entire lactation. SCC counts were not significantly different in SRLV-infected and unifected animals.LimitationsFurther parameters, such as body condition score or clinical mastitis, that were not available may have clarified the underlying cause of milk yield drop.ConclusionsThe study demonstrates substantial production losses in an SRLV-affected flock and highlights the impact of the virus on a farm's economic viability
