An Index of Child Well-being in the European Union

While the living conditions of children and young people in the European Union have gained increasing recognition across the EU, the well-being of children is not monitored on the European level. Based on a rights-based, multi-dimensional understanding of child well-being we analyse data already available for the EU 25, using series data as well as comparative surveys of children and young people. We compare the performance of EU Member States on eight clusters with 23 domains and 51 indicators and give a picture of children’s overall well-being in the European Union. The clusters are children’s material situation, housing, health, subjective well-being, education, children’s relationships, civic participation and risk and safety

The Impact of Children’s Connection to Nature: A Report for the Royal Society for the Protection of Birds (RSPB)

Connecting with nature should be part of every child’s life as it has the potential to aid nature’s revival while benefiting the child. To embed nature connection within our social norms, there is a need to be able to understand the benefits and set targets for levels of nature connection. This report presents findings on the impact of connection to nature from a survey of 775 children, using the child as the unit of analysis, rather than aggregated data. The results demonstrated that children who were more connected to nature had significantly higher English attainment, although this wasn’t repeated for Mathematics. Further, the 1.5 Connection to Nature Index (CNI) level was found to be a significant threshold across other measures, with those children with a CNI of 1.5 or above having significantly higher health, life satisfaction, pro-environmental behaviours and pro-nature behaviours. The analysis found strong correlations between CNI and pro-nature behaviours and pro-environmental behavior. A positive correlation was also evident between CNI and days spent outdoors and days spent in nature over the past week, suggesting that the more time spent in nature is associated with child’s connection to nature. Finally, weak correlations were found between connection to nature, health and life satisfaction. When more refined attainment results for English were explored, (n = 512) further weak correlations were found between English attainment and attendance, English and life satisfaction, and between English attainment and connection to nature. There are a multitude of factors associated with a child’s English attainment, so, although the correlations are weak, it is noteworthy that connection to nature is as important to children’s achievement in English as life satisfaction and attendance at school

Crack healing in cementitious materials including test methods

If concrete is crack free, deleterious substances can be avoided entering the body of the material, that may corrode the rebar or encourage freeze/thaw damage. This paper examines a self healing system of cementitious materials. Microbial induced calcite precipitation was used to heal cracks in concrete with calcite using bacillus bacteria in alkaline conditions to generate a calcite filling material. Self healing of cracked prisms was determined using a water flow and absorption test and the results were expressed to record the healing as a percentage. The findings of the tests showed that a significant degree of self healing had taken place after 56 days after inducing a crack to the concrete prisms and the water flow test was appropriate to determine the degree of self healing taking place. Limitations of this process are such that the process requires a biological laboratory to create the spore impregnated aggregate. Once the aggregate is prepared, the batching process is essentially the same as any normal concrete. A practical use of this system could be developed using cover panels of self healing material to act as permanent formwork, thus placing the healing ingredients where they are needed at a minimum cost. The system has huge potential for the creation of a self repairing sustainable infrastructure

A measure of nature connectedness for children and adults: Validation, performance, and insights

With benefits to both human well-being and pro-nature conservation behaviors, nature connectedness is emerging as an important psychological construct for a sustainable future. The growing research and applied and policy-related interests require a straightforward measure of nature connectedness that is suitable for both children and adult populations. To establish the reliability of the new Nature Connection Index (NCI) three factor analyses were conducted. One was based on a large Monitor of Engagement with the Natural Environment (MENE) dataset for adults (n = 3568) with a replication from data sets collected online (n = 553), and a third used MENE data from children (n = 351). To validate the NCI as a measure for nature connectedness an online comparison study (n = 153) included the NCI alongside other established measures. The results showed that the NCI was a reliable and valid scale that offers a short, simple alternative to other measures of nature connectedness, particularly for populations including both children and adults, measured face to face or online. The utility of the NCI is also supported, with variations associated with various pro-environmental and pro-conservation behaviors observed, and importantly the NCI also revealed changes in nature connectedness across the lifespan.N/

Relative impact of Fiscal and Monetary Policy on the Growth of Small and Medium Scale Enterprises in Nigeria

In order to determine the influence of fiscal and monetary policies on the growth of SMEsin Nigeria, this study employed time series data for the period 1986-2015, adopting the OLS estimation technique. The result suggeststhat fiscal policy is more effective in stimulating the growth performance of Nigeria SMEs comparing to monetary policy. Hence, the suggestion that government should pay more attention to fiscal policy. A combination of both policies is also recommendedfor optimal performance of the SMEs sector in the Nigerian economy.JEL Codes: E63, O11, O2

An investigation into the hexagonal phases formed in high-concentration dispersions of well-defined cylindrical block copolymer micelles

<p>This paper presents a detailed analysis of the structure of the hexagonal phase of poly(ferrocenylsilane) (PFS)-based cylindrical micelles found at concentrations above ca. 5 wt. % in non-polar solvents such as decane. Small-angle X-ray scattering indicated that the hexagonal order is not long-range. In all samples, deviations in the lower order peak positions were observed with respect to those expected for a perfect hexagonal lattice, with the degree of deviation correlating with micelle length. Furthermore, analysis of the peak shapes and peak widths suggests that the phase possesses intermediate translational order similar. to the hexatic phase. The observed features can be reproduced by amending Hosemann’s paracrystal theory to include a distribution of lattice parameters to model well and poorly condensed regions. It is proposed that this distribution arises due to the bending and intertwining of individual micelles in a hexagonal lattice, resulting in a kinetically trapped phase that is initially neither perfectly hexagonal nor canonically hexatic but which anneals over time towards a perfect hexagonal lattice.</p

Developing a Global Indicator on Bullying of School-aged Children

The rate of bullying among children is a key indicator of children’s well-being and an important marker for comparing global social development: both victims and perpetrators of bullying in childhood suffer across various dimensions, including personal social development, education, and health, with negative effects persisting into adulthood. For policymakers and professionals working with children, high rates of bullying amongst children should raise warning flags regarding child rights’ failings. Moreover, bullying amongst school-aged children highlights existing inefficiencies in the social system, and the potential for incurring future social costs in the communities and schools in which children live their lives. Inevitably, these concerns have contributed to bullying becoming a globally recognized challenge – every region in the world collects information on children’s experiences of bullying. Yet, despite the identification and monitoring of bullying having global appeal, so far, a validated global measure has not been produced. To fill this gap in knowledge, this paper develops a global indicator on bullying amongst children using existing school-based surveys from around the world. The findings of this paper show that bullying is a complex phenomenon that takes multiple forms, and is experienced to widely varying degrees across the world

Coupled Natural Fusion Enzymes in a Novel Biocatalytic Cascade Convert Fatty Acids to Amines

[Image: see text] Tambjamine YP1 is a pyrrole-containing natural product. Analysis of the enzymes encoded in the Pseudoalteromonas tunicata “tam” biosynthetic gene cluster (BGC) identified a unique di-domain biocatalyst (PtTamH). Sequence and bioinformatic analysis predicts that PtTamH comprises an N-terminal, pyridoxal 5′-phosphate (PLP)-dependent transaminase (TA) domain fused to a NADH-dependent C-terminal thioester reductase (TR) domain. Spectroscopic and chemical analysis revealed that the TA domain binds PLP, utilizes l-Glu as an amine donor, accepts a range of fatty aldehydes (C(7)–C(14) with a preference for C(12)), and produces the corresponding amines. The previously characterized PtTamA from the “tam” BGC is an ATP-dependent, di-domain enzyme comprising a class I adenylation domain fused to an acyl carrier protein (ACP). Since recombinant PtTamA catalyzes the activation and thioesterification of C(12) acid to the holo-ACP domain, we hypothesized that C(12) ACP is the natural substrate for PtTamH. PtTamA and PtTamH were successfully coupled together in a biocatalytic cascade that converts fatty acids (FAs) to amines in one pot. Moreover, a structural model of PtTamH provides insights into how the TA and TR domains are organized. This work not only characterizes the formation of the tambjamine YP1 tail but also suggests that PtTamA and PtTamH could be useful biocatalysts for FA to amine functional group conversion

E-service quality: An investigation of its key dimensions and the discriminatory power in the residential property sector

Research Statement: With an increase in competition within the South African property sector, real estate agencies need to ensure that their channels are as effective as possible. Using the Internet and mobile technologies represents a new means to reach customers and achieve lower operating costs. This study seeks to ascertain which factors potential buyers consider important when perusing residential property in an online environment. Hence, the dimensions of e-service quality, which constitute their online experience, will be explored. In addition, this research explores buyer typologies and probes whether other forms of technology, such as a mobile interface, may be of commercial value to the realtor. Methodology: The empirical analysis was conducted by means of a quantitative survey. A questionnaire was designed to test the application of the e-service quality construct in the South African real-estate sector. Data was obtained from 300 respondents, across the age spectrum, who filled the criteria of being prospective buyers. Convenience sampling was primarily used to collect responses as the researchers were unable to obtain access to a specific database of listed property buyers. Results & Conclusion: As mirrored in other studies of this nature, it was found that trust is paramount when initiating property sales online. All other variables in the construct (site features, information, accessibility, communication, reliability, responsiveness and personalisation) also proved significant. A cluster analysis revealed that older respondents preferred a higher level of support - across all attributes of e-service quality - when interacting with online property services. Lastly, the mobile interface appears to appeal to 'students' as well as 'mature workers'. It is surmised that these individuals have access to smart phones capable of being used for accessing property portals. However, the 'young workers' appear less enthusiastic about the mobile interface, seemingly preferring to either access such portals via the Internet or visiting agents personally

Effect of processing variables and bulk composition on the surface composition of spray dried powders of a model food system

Abstract The surface compositions of food powders created from spray drying solutions containing various ratios of sodium caseinate, maltodextrin and soya oil have been analysed by Electron Spectroscopy for Chemical Analysis. The results show significant enrichment of oil at the surface of particles compared to the bulk phase and, when the non-oil components only are considered, a significant surface enrichment of sodium caseinate also. The degree of surface enrichment of both oil and sodium caseinate was found to increase with decreasing bulk levels of the respective components. Surface enrichment of oil was also affected by processing conditions (emulsion drop size and drying temperature), but surface enrichment of sodium caseinate was relatively insensitive to these. The presence of "pock marks" on the particle surfaces strongly suggests that the surface oil was caused by rupturing of emulsion droplets at the surface as the surrounding matrix contracts and hardens
