As with many industries, digital disruption will play a major role in shaping agriculture over the coming years as decisions become increasingly data driven. A significant proportion of this data will come from on-farm sensors that are becoming easier to source and deploy. While access to sensors is becoming increasingly cost effective, accessing and integrating the data they provide is still a major issue for many, due to the use of different standards for describing and sharing the data. The Soil sensing - new technology for tracking soil water availability, managing risk and improving management decisions project has developed a distributed system that addresses the technical challenge of federating disparate data sources through the use of a software mediation layer and a semantically enabled metadata harvest, search and discovery tool. These web services, the O&M Translator and the Data Brokering Layer, allow a unified and federated view of the data, enabling integrated search and discovery and provide access through a SOS compliant API, delivering the data to client using the O&M data model and a TimeseriesML representation. The resulting Data Stream Integrator is already being tested in applications such as SoilWaterApp.

There are a multitude of reasons that a teletinnitus program can be beneficial, not only to the patients, but also within the hospital and audiology department. The ability to use technology for the purpose of tinnitus management allows for improved appointment access for all patients, especially those who live at a distance, has been shown to be more cost effective when the patients travel is otherwise monetarily compensated, and allows for multiple patient's to be seen in the same time slots, allowing for greater access to the clinic for the patients wishing to be seen in-house. There is also the patient's excitement in being part of a new technology-based program. The Gulf Coast Veterans Health Care System (GCVHCS) saw the potential benefits of incorporating a teletinnitus program and began implementation in 2013. There were a few hurdles to work through during the beginning organizational process and the initial execution of the program. Since the establishment of the Teletinnitus program, the GCVHCS has seen an enhancement in patient care, reduction in travel compensation, improvement in clinic utilization, clinic availability, the genuine excitement of the use of a new healthcare media amongst staff and patients, and overall patient satisfaction.

Scale Assessment

Studies have shown micro-hydropower (MHP) opportunities for energy recovery and CO2 reductions in the water sector. This paper conducts a large-scale assessment of this potential using a dataset amassed across six EU countries (Ireland, Northern Ireland, Scotland, Wales, Spain, and Portugal) for the drinking water, irrigation, and wastewater sectors. Extrapolating the collected data, the total annual MHP potential was estimated between 482.3 and 821.6 GWh, depending on the assumptions, divided among Ireland (15.5–32.2 GWh), Scotland (17.8–139.7 GWh), Northern Ireland (5.9–8.2 GWh), Wales (10.2–8.1 GWh), Spain (375.3–539.9 GWh), and Portugal (57.6–93.5 GWh) and distributed across the drinking water (43–67%), irrigation (51–30%), and wastewater (6–3%) sectors. The findings demonstrated reductions in energy consumption in water networks between 1.7 and 13.0%. Forty-five percent of the energy estimated from the analysed sites was associated with just 3% of their number, having a power output capacity >15 kW. This demonstrated that a significant proportion of energy could be exploited at a small number of sites, with a valuable contribution to net energy efficiency gains and CO2 emission reductions. This also demonstrates cost-effective, value-added, multi-country benefits to policy makers, establishing the case to incentivise MHP in water networks to help achieve the desired CO2 emissions reductions targets.

Abstract Between 2000 and 2013, over 8,000 students studied the module Reading Classical Latin at the Open University, the United Kingdom’s largest distance education provider. But while many learners attained high grades, a significant proportion withdrew from study or failed the module. In 2015, the original module was replaced with a completely new course, Classical Latin: The Language of Ancient Rome. This article details the innovative ways in which new technology and pedagogical theory from Modern Foreign Language (MFL) learning were drawn on by the team designing this new module, resulting in a learning experience which gives greater emphasis to elements such as spoken Latin, the intrinsic pleasure of reading, and cultural context. The (largely positive) effects of these pedagogical changes on student success and satisfaction are subsequently analysed using a rich mix of qualitative and quantitative data. Finally, the authors reflect on lessons learned and the possibilities for future research and enhancement.

The number of data sources available for academic research on retirement economics and policy has increased rapidly in the past two decades. Data quality and comparability across studies have also improved considerably, with survey questionnaires progressively converging towards common ways of eliciting the same measurable concepts. Probability-based Internet panels have become a more accepted and recognized tool to obtain research data, allowing for fast, flexible, and cost-effective data collection compared to more traditional modes such as in-person and phone interviews. In an era of big data, academic research has also increasingly been able to access administrative records (e.g., Kostøl and Mogstad, 2014; Cesarini et al., 2016), private-sector financial records (e.g., Gelman et al., 2014), and administrative data married with surveys (Ameriks et al., 2020), to answer questions that could not be successfully tackled otherwise.

Several outbreaks of Salmonella enterica infections have been linked to tomatoes. One cost-effective way to complement on-farm preventive Good Agricultural Practices is to identify cultivars with inherent decreased susceptibility to Salmonella colonization. Fruit and leaves of 13 tomato cultivars with distinct phenotypes were screened to evaluate their susceptibility to Salmonella epiphytic colonization. Field-grown fruit or gnotobiotically grown seedling leaves were spot inoculated in replicate with either Salmonella Typhimurium LT2 or a tomato outbreak–associated strain of Salmonella Newport. Initial loads of the Salmonella inocula were 2.5 log CFU per fruit and 3.5 or 7.0 log CFU per seedling. Salmonella cells were retrieved and enumerated using direct plating after 24 h of incubation at room temperature for fruit and 72 h at 26°C during the day and 18°C at night for seedling leaves. Epiphytic colonization of fruit by S. enterica was cultivar-dependent and serotype-specific, but did not necessarily correlate with leaf colonization. Fruit of cultivar Heinz-1706 were the least colonized by Salmonella Newport, while the highest populations were retrieved from fruit of Nyagous. By contrast, seedling leaves supporting the lowest populations were Florida 91 VF and the highest were Virginia Sweets for Salmonella Newport. For Salmonella Typhimurium the lowest was Nyagous and the highest was Heinz-1706 and Moneymaker. The tomato outbreak strain of Salmonella Newport attained higher population densities on fruit than did Salmonella Typhimurium, suggesting better adaptation to tomato fruit colonization. Salmonella Newport populations were significantly lower on leaves, but not fruit of the near-isogenic line Movione, compared with the parent cultivar Moneymaker, suggesting the immunity conferring gene Pto could be responding to this outbreak strain. Susceptibility of tomato fruit to Salmonella colonization is highly variable and could be one criterion for cultivar selection for cultivation.

Summary Background: Congenital heart disease (CHD) is the most common birth defect; however, the underlying etiology is unrecognized in the majority of cases. GATA-binding protein 4 (GATA4), a cardiac transcription factor gene, has a crucial role in the cardiogenesis process; hence, a number of heterozygote sequence variations were identified as a cause of CHD. G296S heterozygote variant is the most frequently reported GATA4 gene sequence alteration. This study aims to investigate the role of G296S variant of the GATA4 gene in Malaysian CHD subjects. Methods: We have investigated 86 Malaysian CHD subjects with cardiac septation defects for the presence of the GATA4 gene heterozygote variant (G296S) by the new technology of high resolution melting (HRM) analysis. Results: Genotyping of G296S (c.886G>A) by HRM analysis shows that all the sample genotypes were of the wild GG type genotype and the heterozygote mutant GA genotype was totally absent from this study cohort. Conclusions: The results of our study showed that the G296S variant of the GATA4 gene was not associated with the development of CHD in Malaysian subjects. The use of HRM analysis proved a cost-effective, high-throughput, specific and sensitive genotyping technique which eliminates the need for unnecessary sequencing.
