‘I Updated the <ref>’: The Evolution of References in the English Wikipedia and the Implications for Altmetrics

With this work, we present a publicly available dataset of the history of all the references (more than 55 million) ever used in the English Wikipedia until June 2019. We have applied a new method for identifying and monitoring references in Wikipedia, so that for each reference we can provide data about associated actions: creation, modifications, deletions, and reinsertions. The high accuracy of this method and the resulting dataset was confirmed via a comprehensive crowdworker labelling campaign. We use the dataset to study the temporal evolution of Wikipedia references as well as users’ editing behaviour. We find evidence of a mostly productive and continuous effort to improve the quality of references: (1) there is a persistent increase of reference and document identifiers (DOI, PubMedID, PMC, ISBN, ISSN, ArXiv ID), and (2) most of the reference curation work is done by registered humans (not bots or anonymous editors). We conclude that the evolution of Wikipedia references, including the dynamics of the community processes that tend to them should be leveraged in the design of relevance indexes for altmetrics, and our dataset can be pivotal for such an effort.

Leveraging the Intersection between Age-friendly Universities and Age-Friendly Communities

Age-friendly Universities represent a growing contribution to the worldwide age-friendly movement. For universities, the international effort aims to highlight the role higher education plays in responding to the opportunities associated with an aging population. The initiative outlines ten principles to engage older adults via collegiate mission pertaining to research, education and service. Shared practices suggest diverse and unique application of the guiding tenets across participating colleges and universities. However Age-friendly Universities are also part of a broader ecosystem, situated in geographic locales reflecting actual or prospective age-friendly community status. The global Age-friendly Community movement is a decade-old effort to improve the environments in which we age via a cyclical process. This paper identifies the intersection between Age-friendly University principles and Age-Friendly Community processes and discusses reciprocal considerations for mutual advancement of the broader movement.

Batik Grajen: Eco-friendly batik utilizing wood waste for batik dye

Grajen Batik is batik which coloring process uses natural dyes from grajen (sawdust) waste. Batik Grajen was developed by batik artisans in the Bulakan area, Sukoharjo, Central Java. The development of Batik Grajen is ecologically alluring since the Bulakan community processes sawdust from the sawmill industry into eco-friendly batik dyes. Sawdust (grajen) waste is used as batik dye because of the pigment contained. The dyes produced are safer and more eco-friendly than synthetic dyes. The effort made by the Bulakan community through Batik Grajen products is a creative solution to respond to environmental problems, especially waste problems that can be recycled into creative products with economic value.

The Ecology of Hyperparasitoids

Hyperparasitoids are some of the most diverse members of insect food webs. True hyperparasitoids parasitize the larvae of other parasitoids, reaching these larvae with their ovipositor through the herbivore that hosts the parasitoid larva. During pupation, primary parasitoids also may be attacked by pseudohyperparasitoids that lay their eggs on the parasitoid (pre)pupae. By attacking primary parasitoids, hyperparasitoids may affect herbivore population dynamics, and they have been identified as a major challenge in biological control. Over the past decades, research, especially on aphid- and caterpillar-associated hyperparasitoids, has revealed that hyperparasitoids challenge rules on nutrient use efficiency in trophic chains, account for herbivore outbreaks, or stabilize competitive interactions in lower trophic levels, and they may use cues derived from complex interaction networks to locate their hosts. This review focuses on the fascinating ecology of hyperparasitoids related to how they exploit and locate their often inconspicuous hosts and the insect community processes in which hyperparasitoids are prominent players. Expected final online publication date for the Annual Review of Entomology, Volume 67 is January 2022. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.

Equality in Community Engagement: A Scoping Review of Evidence from Research and Practice in Scotland

In Scotland, innovative designs for community engagement have been developed by national and local governments, public authorities, and civil society organisations, leading to a wealth of literature and research. This evidence review of 79 articles and reports, explores the intersection between community engagement and inequality in Scotland. We find that the ways in which equality must be supported within community processes are often overlooked. Community engagement must be placed in the context of broader democratic innovation and citizenship at regional, national and global scale in order to become future proof. Appropriate resources are required to avoid replicating systemic inequalities as well as to support the development of a variety of institutions, processes and methods that cater for groups often mislabelled as ‘hard to reach’ but that are perhaps best seen as ‘easy to ignore’ ( Matthews et al. 2012 ). The paper highlights key learning and strategic considerations to inform practice in Scotland and beyond. The findings and recommendations are of relevance to reformers, innovators, researchers, practitioners and policymakers working across diverse policy areas and levels of governance.

Studies at Large Spatial Scales, Citizen Science, and the Classification of Habitats

Technological advances over the past forty years have greatly increased the opportunities for the study of population and community processes over large spatial distances and to follow changes in large populations. A number of important developments, such as remote sensing, has made this possible. Remote sensing is the measurement of reflected, emitted, or backscattered electromagnetic radiation from the Earth’s surface by using instruments placed at a distance, most often on a satellite, although aircraft are frequently used. Methods to study populations over large spatial scales are introduced. The use of satellites and remote sensing using piloted aircraft and drones and distributed networks of sensors such as camera traps is described. The creation of biodiversity record systems and the development of citizen science with the internet are described. The perception of the change in species richness with spatial scale is discussed. The concept of ecosystem services is introduced. A general system for habitat classification is presented.

Education for Sustainable Development in Spanish University Education Degrees

This work presents an analysis of student perception of Spanish university education degrees regarding their training in sustainable development. A sample of 942 students was used. The methodology consists of analyzing the results of a survey answered by the first- and fourth-year students from nine education degree courses in four Spanish universities. Comparison of the perception of learning by fourth-year students against those of the first year enables improvements in learning regarding sustainability to be ascertained. The questionnaire consists of 18 questions concerning four sustainability competencies: C1-Critical contextualization of knowledge, C2-Sustainable use of resources, C3-Participation in community processes, and C4-Ethics. Two composite indicators are defined to analyze the absolute learning (achieved on completion of their studies) and the relative learning (achieved with respect to what should have been achieved) declared by the students in each competency, degree and university. The results show that students declare an improvement in all their sustainability competencies, although the results of the final learning are far from those expected: they have learned only 27% of what they should have learned. Moreover, the learning achieved in the four competencies depends on the degree and the university.

Deciphering active prophages from metagenomes

ABSTRACTTemperate phages (prophages) are ubiquitous in nature and persist as dormant components of host cells (lysogenic stage) before activating and lysing the host (lytic stage). Actively replicating prophages contribute to central community processes, such as enabling bacterial virulence, manipulating biogeochemical cycling, and driving microbial community diversification. Recent advances in sequencing technology have allowed for the identification and characterization of diverse phages, yet no approaches currently exist for identifying if a prophage has activated. Here, we present PropagAtE (Prophage Activity Estimator), an automated software tool for estimating if a prophage is in the lytic or lysogenic stage of infection. PropagAtE uses statistical analyses of prophage-to-host read coverage ratios to decipher actively replicating prophages, irrespective of whether prophages were induced or spontaneously activated. We demonstrate that PropagAtE is fast, accurate and sensitive, regardless of sequencing depth. Application of PropagAtE to prophages from 348 complex metagenomes from human gut, murine gut and soil environments identified distinct spatial and temporal prophage activation signatures, with the highest proportion of active prophages in murine gut samples. Among the soil habitats evaluated (bog, fen and palsa), we identified unique populations of Myxococcales, Acetobacteraceae and Acidimicrobiaceae prophages to be active in fen, palsa and bog habitats, respectively. Within the human gut, 11 prophage populations, some encoding the sulfur metabolism gene cysH or a rhuM-like virulence factor, were consistently present over time but not active. Overall, PropagAtE will facilitate accurate representations of viruses in microbiomes by associating prophages with their active roles in shaping microbial communities in nature.
