Review on heatwaves: a risk perspective
Full text linkCurrent anthropogenic climate change is increasing the occurrence and magnitude of heatwaves causing closely interconnected and interdependent risks across multiple domains, such as environmental and human health, water and food security, etc. The following systematic literature review synthesizes the state of the art concerning risks related to heatwaves by analyzing 1459 publications. Since risks arise from the interaction of hazard, exposure, and vulnerability, publications were first classified by risk components and then further categorized by research fields: healthcare, society, ecosystem, agriculture, infrastructure, and heritage. The analysis allowed the identification of gaps in the current research with implications for policies and practical applications of risk assessments. First, only 3.1% of the revised literature integrates all three components in risk assessments. Second, most of the literature provides average risks over several heatwave events, thus neglecting critical factors like heatwave magnitude and duration. Third, the absence of standardized indices for identifying and classifying heatwaves hinders effective comparisons of results within the same field. It is recommended that future studies in the same field adopt a common methodology and that the above gaps are taken into account as this would enable building more robust and coherent scientific evidence while reducing ambiguities and uncertainties in risk estimates. Decisionmakers may otherwise struggle to develop effective heatwave adaptation and mitigation strategies if risk assessments are inconsistent or unreliable, and fail to account for risk interdependencies across different domains. More research is needed to develop quantitative frameworks that estimate heatwave risks by summing contributions from each affected domain. This is particularly important, as most of the papers reviewed only focused on healthcare (61.1%) or ecosystems (16.3%). However, we acknowledge that this literature review may have excluded some relevant studies, such as those in the heritage field, due to the specific search string applied in our methodology
A novel framework for the assessment of hydro-meteorological risks taking into account nature-based solutions
Full text linkThe growing exposure to hydro-meteorological hazards translates into increasing risks for people, territories, and ecosystems. The frequency of occurrence and magnitude of these hazards are expected to further increase in the next decades urging tangible decisions to reduce anthropogenic climate change and adapt to the risks to be faced. In this context, risk assessment is an essential tool for becoming aware of dangers and taking countermeasures. This paper proposes a novel predictive, yet holistic, framework that allows to take into account multiple risks classified according to six research fields, i.e. healthcare, society, ecosystem, heritage, infrastructure, and agriculture. Each contribution to the overall risk is evaluated in terms of economic losses and carbon-dioxide emissions that in turn affect adaptation ability and contribute to exacerbating climate change. Both economic losses and emissions are estimated as a cost per day to support political decision-making processes. In this regard, the framework integrates the effects of adaptation and mitigation strategies to include societal capacities to cope with hazards and respond to their potential consequences. As a guideline, this study reports a preliminary investigation of a heatwave event over a portion of Bologna Province (Italy) concluding that the current use of air-conditioning systems is not sustainable leading to a huge amount of losses. The novel framework can be adopted in future studies for selecting more cost-effective strategies as expected for Nature-based Solutions (NbS). The framework can indeed stand as a tool for estimating the local impact of NbS in the current or future climate scenarios
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
