TL;DR: Wang et al. as mentioned in this paper explored the impact of farmland transfer on the multidimensional relative poverty of the elderly in rural areas to provide a reference for the study of rural land transfer in China and improve the welfare system for the elderly.
Abstract: This study explores the impact of farmland transfer on the multidimensional relative poverty of the elderly in rural areas to provide a reference for the study of rural land transfer in China and improve the welfare system for the elderly. Based on the China Family Panel Studies (CFPS) rural sample data in 2018, this paper uses the AF multidimensional index measurement method to assess multidimensional relative poverty in rural areas. Logit regression estimation examines the single index poverty of rural older adults transferred from rural land and the impact of multidimensional relative poverty, using the propensity score matching method (PSM) to analyze the results’ robustness. The transfer of agricultural land has different impacts on the poverty of different rural elderly poverty indicators and negatively affects the comprehensive effect of rural elderly poverty. The transfer of agricultural land significantly alleviates rural elderly poverty. Reasonable and effective transfer of agricultural land, together with improved rural social security and a caring service system for the elderly, will promote the continuous operation of large-scale agricultural operations and alleviate rural elderly poverty.

TL;DR: An artificial intelligence based method applied by specialists to set intervention priorities, support maintenance management of the examined building and minimise human error during data collection and uncertainty related to making decisions is applied.
Abstract: The maintenance of buildings is a highly complex decision process, which is generally due to professional experts having to consider several arduous evaluations, especially regarding uncertainty related to why, when and how to intervene. This study concerns the analysis of the uncertainty associated with professional experts’ surveys during the decision-making process during building maintenance. For this purpose, a case study of a timber-structure building was examined. An expert panel of 66 professionals with expertise in construction engineering carried out a systematic and automated evaluation. This kind of digital method is capable of managing the uncertainty associated with the evaluation processes by different specialists. Experts can evaluate various nuances and approximations in the model’s input parameters. The fuzzy model helps to harmonize the results since minor variations in the evaluation of the input parameters do not generate a large dispersion over the model’s output variable. The novelty of this study concerns the application of a digital methodology based on a fuzzy logic model to assist a professional expert panel in different areas—architecture, engineering and construction. This study is oriented through an artificial intelligence based method applied by specialists to set intervention priorities, support maintenance management of the examined building and minimise human error during data collection and uncertainty related to making decisions. The lessons learned from the results obtained in this study promote the use of this kind of digital tool to manage the uncertainty associated with in-situ visual inspections.

TL;DR: In this paper , a digital management system based on fuzzy logic was used to evaluate the functional service life of two heritage timber buildings in Valdivia (Chile) and the assessments of 40 professional experts (4 onsite visual inspections and 36 virtual inspections) were compared to evaluate relative accuracy and usefulness of the on-site and web-based instruments.
Abstract: The construction engineering and management sector is facing rapid technological disruption due to the extensive adoption of digital tools. The main aim of this research was to assess the accuracy and usefulness of web-based instruments used for the evaluation and mensuration of built environment characteristics. Through on-site visits and two web-based tools, a digital management system based on fuzzy logic was used to evaluate the functional service life of two heritage timber buildings in Valdivia (Chile). The assessments of 40 professional experts (4 on-site visual inspections and 36 virtual inspections) were compared to evaluate the relative accuracy and usefulness of the on-site and web-based instruments. Web-based audits, which used Google Street View and Google Maps, tended to agree strongly with on-site audits on the functional degradation of the timber structures (vulnerabilities and external hazard affections). While web-based tools do not offer a perfect substitute for on-site audits, they do allow for preliminary audits to be performed accurately from remote locations, potentially saving time and cost and increasing the effectiveness of subsequent on-site visits. The study findings may be useful to industry stakeholders in understanding the early impacts of the use of new remote digital inspection tools on the construction industry.

TL;DR: A systematic literature review was carried out to analyse the academic articles within the Industry 4.0 topic that were published online until the end of June 2016 and indicates existing deficiencies and potential research directions through proposing a research agenda.
Abstract: Over the last few years, the fourth industrial revolution has attracted more and more attentions all around the world. In the current literature, there is still a lack of efforts to systematically review the state of the art of this new industrial revolution wave. The aim of this study is to address this gap by investigating the academic progresses in Industry 4.0. A systematic literature review was carried out to analyse the academic articles within the Industry 4.0 topic that were published online until the end of June 2016. In this paper, the obtained results from both the general data analysis of included papers (e.g. relevant journals, their subject areas and categories, conferences, keywords) and the specific data analysis corresponding to four research sub-questions are illustrated and discussed. These results not only summarise the current research activities (e.g. main research directions, applied standards, employed software and hardware), but also indicate existing deficiencies and potential re...

TL;DR: In this paper, a comprehensive post-efficacy strategy for the next steps to ensure vaccination of the global population is now required, including how to manufacture billions of doses of high-quality vaccines, support for vaccine purchase, coordination of supply, equitable distribution of vaccines and the logistics of global vaccine delivery, all of which are a prelude to a massive vaccination campaign targeting people of all ages.
Abstract: After the recent announcement of COVID-19 vaccine efficacy in clinical trials by several manufacturers for protection against severe disease, a comprehensive post-efficacy strategy for the next steps to ensure vaccination of the global population is now required. These considerations should include how to manufacture billions of doses of high-quality vaccines, support for vaccine purchase, coordination of supply, the equitable distribution of vaccines and the logistics of global vaccine delivery, all of which are a prelude to a massive vaccination campaign targeting people of all ages. Furthermore, additional scientific questions about the vaccines remain that should be answered to improve vaccine efficacy, including questions regarding the optimization of vaccination regimens, booster doses, the correlates of protection, vaccine effectiveness, safety and enhanced surveillance. The timely and coordinated execution of these post-efficacy tasks will bring the pandemic to an effective, and efficient, close.
