Search has been central to the development of the Web, enabling increasing engagement by a growing number of users. Proposals for the redecentalisation of the Web such as SOLID aim to give individuals sovereignty over their data by means of personal online datastores (pods). However, it is not clear whether search utilities that we currently take for granted would work efficiently in a redecentralised Web. In this paper we discuss the challenges of supporting distributed search on a large scale of pods. We present a system architecture which can allow research, development and testing of new algorithms for decentralised search across pods. We undertake an initial validation of this architecture by usage scenarios for decentralised search under user-defined access control and data governance constraints. We conclude with research directions for decentralised search algorithms and deployment.

This paper discusses a series of discusses how web sites now report international water project information, and maps the combined donor investment in more than 6000 water projects, active since 1995. The maps show donor investment:  • has addressed water scarcity,  • has improved access to improvised water resources,  • correlates with growth in GDP,  • appears to show a correlation with growth in net private capital flow,  • does NOT appear to correlate with growth in GNI. Evaluation indicates problems in the combined water project portfolios for major donor organizations: •difficulties in grouping projects over differing Sector classifications, food security, or agriculture/irrigation is the most difficult.  • inability to map donor projects at the country or river basin level because 60% of the donor projects include no location data (town, province, watershed) in the title or abstracts available on the web sites.  • no means to identify donor projects with utilization of water resources from training or technical assistance.  • no information of the source of water (river, aquifer, rainwater catchment).  • an identifiable quantity of water (withdrawal amounts, or increased water efficiency) is not provided.  • differentiation between large scale verses small scale projects. Recommendation: Major donors need to look at how the web harvests and combines their information, and look at ways to agree on a standard template for project titles to include more essential information. The Japanese (JICA) and the Asian Development Bank provide good models.

AbstractSelf-administered web-based 24-h dietary recalls (24 hR) may save a lot of time and money as compared with interviewer-administered telephone-based 24 hR interviews and may therefore be useful in large-scale studies. Within the Nutrition Questionnaires plus (NQplus) study, the web-based 24 hR tool Compl-eat™ was developed to assess Dutch participants’ dietary intake. The aim of the present study was to evaluate the performance of this tool against the interviewer-administered telephone-based 24 hR method. A subgroup of participants of the NQplus study (20–70 years, n 514) completed three self-administered web-based 24 hR and three telephone 24 hR interviews administered by a dietitian over a 1-year period. Compl-eat™ as well as the dietitians guided the participants to report all foods consumed the previous day. Compl-eat™ on average underestimated the intake of energy by 8 %, of macronutrients by 10 % and of micronutrients by 13 % as compared with telephone recalls. The agreement between both methods, estimated using Lin's concordance coefficients (LCC), ranged from 0·15 for vitamin B1 to 0·70 for alcohol intake (mean LCC 0·38). The lower estimations by Compl-eat™ can be explained by a lower number of total reported foods and lower estimated intakes of the food groups, fats, oils and savoury sauces, sugar and confectionery, dairy and cheese. The performance of the tool may be improved by, for example, adding an option to automatically select frequently used foods and including more recall cues. We conclude that Compl-eat™ may be a useful tool in large-scale Dutch studies after suggested improvements have been implemented and evaluated.

Abstract Microplastics (MPs) pollution has garnered significant interest as a serious environmental problem. To date, a large amount of research has been published on this topic. We analyzed the related studies to assess the global developments of MPs regarding the evolution, research trends, and hotspots by bibliometric. A total of 2,872 bibliographic records were retrieved from the Web of Science Core Collection, and CiteSpace 5.4 was used for bibliometrics. The results visually displayed the contributing countries, institutions, authors, keywords, and potential research directions in the MPs fields. The scientific developments in this field began in 2004 and have accelerated considerably since 2012. China and the USA are the leading countries in MPs research. The research on MPs is multidisciplinary and involves Ecology, Chemistry, Molecular Biology, Environmental Science, and Oceanography. Among these, Oceanography was the most connected with MPs and was the most well-developed. Overall, we mapped the development of MPs research and attempted a comprehensive discussion and understanding of scientific advances, as well as the progress made.
