Diversity of Expertise is Key to Scientific Impact: a Large Scale Analysis in the Field of Computer Science
<p><strong>This repository is companion to a research paper with the following abstract:</strong></p> <p>Understanding the relationship between the composition of a research team and the potential impact of their research papers is crucial as it can steer the development of new science policies for improving the research enterprise. Numerous studies assess how the characteristics and diversity of research teams can influence their performance across several dimensions: ethnicity, internationality, size, and others. In this paper, we explore the impact of diversity in terms of the authors’ expertise and skills. To this purpose, we retrieved 114K papers in the field of Computer Science and analysed how the diversity of research fields within a research team relates to the number of citations their papers received in the upcoming 5 years. The results show that two different metrics reflecting the diversity of expertise are directly associated with the number of citations. This suggests that, at least in Computer Science, diversity of expertise is key to scientific impact.</p>
Impact of elbow supports use on chest compression quality: a crossover simulation study
<p>Abstract<br> During chest compressions, a downward force is generated by the rescuer’s body through straightened arms to the patient’s chest. If the elbows are not straight, the depth of chest compressions could be reduced. Such a situation could occur during<br> prolonged chest compressions or when the rescuer must wear protective equipment, such as during the coronavirus disease 2019 (COVID-19) pandemic, and can lead to reduced chest compression quality. This study aimed to compare the quality of chest compressions performed using elbow supports to limit the elbows’ range of motion with that of standard chest compression (SCC). This prospective, randomized controlled, crossover simulation trial was conducted from October to December 2018. It included 34 participants who were certified in Basic Life Support with an overall compression score of ≥80% in the preliminary evaluation. They were randomly assigned to the immediate intervention (elbow support chest compression (ESCC)) or wait-list control (SCC) groups, and were asked to perform hands-only cardiopulmonary resuscitation for 8 minutes with and without elbow supports, respectively. After 1 week, the participants were made to switch groups, and the quality of chest compressions between the two groups was compared. The study findings showed that the ESCC group had a significantly higher overall compression score than the SCC group (82.85 ± 13.73% vs. 76.11 ± 19.19%, respectively, p = 0.044). No difference was observed in the chest compression depth between men and women in the ESCC group (53.12 ± 6.14 mm vs.<br> 49.13 ± 3.23 mm, respectively, p = 0.053), but a significant difference was observed between those of the SCC group (53.18 ± 6.58 mm vs. 47.87 ± 5.23 mm, respectively, p = 0.026). Thus, elbow supports could assist rescuers in performing more effective<br> chest compressions, especially for females or in situations where compression quality could be affected.</p>
Warming and grazing independently and interactively impact plant defenses and palatability
<p>The ecological impacts of multiple stressors are hard to predict but important to understand. When multiple stressors influence foundation species, the effects can cascade throughout the ecosystem. Gulf of Mexico seagrass ecosystems are currently experiencing a suite of novel stressors, including warmer water temperatures and increased herbivory due to tropicalization and conservation efforts. We investigated the impact of warming temperatures and grazing history on plant performance, morphology, and palatability by integrating a mesocosm study using the seagrass <em>Thalassia testudinum</em> with feeding trials using the sea urchin <em>Lytechinus variegatus</em>. Warming temperatures negatively impacted <em>T. testudinum </em>tolerance traits, reducing belowground biomass by 34%, productivity by 74%, shoot density by 10%, and the number of leaves per plant by 24%, and negatively impacted resistance traits through 13% lower toughness of young leaves and a trend for reduced leaf carbon:nitrogen. <em>Lytechinus variegatus</em> individuals preferred to consume plants grown under heated conditions, which supports findings of enhanced palatability. Simulated turtle grazing impacted more plant traits than grazing by other herbivores, potentially diminishing plant resilience to future disturbances through reduced rhizome non-structural carbohydrate concentrations and increasing palatability through reduced fiber content and 23% lower leaf carbon:phosphorus. Simulated turtle, simulated parrotfish, and urchin grazing reduced leaf carbon:nitrogen by 11%, also potentially increasing nutritive value. Interactions between warming temperatures and grazers on plant traits were additive for 16 out of 19 response variables. However, the stressors non-additively impacted the number of leaves per plant, fiber content, and epiphyte load. We suggest that the impacts of grazers on leaf turnover rate and leaf age may vary based on water temperature, potentially driving these interactions. Overall, increased temperatures and grazing pressure will likely reduce seagrass resilience, structure, and biomass, potentially impacting feedback systems and producing negative consequences for seagrass cover, associated species, and ecosystem services.</p>

Newspaper Coverage and Framing of Bats, and Their Impact on Readership Engagement
<p>Dataset underpinning the following study: </p> <p>Abstract: The media is a valuable pathway for transforming people’s attitudes towards conservation issues. Understanding how bats are framed in the media is hence essential for bat conservation, particularly considering the recent fearmongering and misinformation about the risks posed by bats. We reviewed bat-related articles published online no later than 2019 (before the recent COVID19 pandemic), in 15 newspapers from the five most populated countries in Western Europe. We examined the extent to which bats were presented as a threat to human health and the assumed general attitudes toward bats that such articles supported. We quantified press coverage on bat conservation values and evaluated whether the country and political stance had any information bias. Finally, we assessed their terminology, and, for the first time, modelled the active response from the readership based on the number of online comments. Out of 1096 articles sampled, 17% focused on bats and diseases, 53% on a range of ecological and conservation topics, and 30% only mention bats anecdotally. While most of the ecological articles did not present bats as a threat (97%), most articles focusing on diseases did so (80%). Ecosystem services were mentioned on very few occasions in both types (<30%), and references to the economic benefits they provide were meagre (<4%). Disease-related concepts were recurrent, and those articles that framed bats as a threat were the ones that garnered the highest number of comments. Therefore, we encourage the media to play a more proactive role in reinforcing positive conservation messaging by presenting the myriad ways in which bats contribute to safeguarding human well-being and ecosystem functioning.</p>

Data for: Functional response metrics explain and predict high but differing ecological impacts of juvenile and adult lionfish
<p>Recent accumulation of evidence across taxa indicates that the ecological impacts of invasive alien species are predictable from their Functional Response (FR; e.g. the maximum feeding rate) and Functional Response Ratio (FRR; the FR attack rate/handling time ratio). Here, we experimentally derive these metrics to predict the ecological impacts of both juvenile and adult lionfish (<em>Pterois volitans</em>), one of the world's most damaging invaders, across representative and likely future prey types. Potentially prey-population destabilising Type II FRs were exhibited by both life stages of lionfish towards four prey species: <em>Artemia salina</em>, <em>Gammarus oceanicus</em>, <em>Palaemonetes varians</em> and <em>Nephrops norvegicus</em>. FR magnitudes revealed ontogenetic shifts in lionfish impacts, while lionfish FRR values were substantially higher than mean FRR values across known damaging invasive taxa. Thus, both life stages of lionfish are predicted to contribute to differing but high ecological impacts across prey communities, including commercially important species. With lionfish invasion ranges currently expanding across multiple regions globally, efforts to reduce lionfish numbers and population size structure, and provision of prey refugia through habitat complexity, might reduce their impacts. However, early detection and complete eradication of individuals located in new regions is advised.</p>
