Multi-Level Governance: Mainstreaming Climate Commitments. In Urban climate action: Policy brief series
No full textThe Urban climate action: Policies Briefs series has been developed by the UNESCO Chair on Urban Resilience at the University of Southern Denmark (SDU.Resilience), in collaboration with authors from the Sant’Anna School of Advanced Studies; the Royal Holloway University of London; the Responsible Risk Resilience Centre (R3C) of Politecnico di Torino; the Climate Policy Initiative (CPI); the German Development Cooperation (GIZ); the Climate Service Center Germany (GERICS); and the Global Green Growth Institute (GGGI).
39% of the NDCs analyzed identified climate hazards that are currently affecting cities in their countries - or might affect them in the future. The climate hazards referred to in the NDCs include floods; droughts; sea level rises; storm events; temperature rises; heat and cold waves; land degradation; saltwater intrusion; water acidification; and wildfires. The Urban climate action: Policies briefs series uses the analysis of the urban context of the NDCs to provide recommendations for policymakers. The recommendations are intended to encourage informed decision-making on specific urban climate-related issues. Based on the analysis of urban-related content in the NDCs, seven thematic Policy Briefs have been produced on the following key topics:
Multilevel Governance; Urban Climate Adaptation; Urban Climate Finance; Nature Based Solutions; Disaster Risk Reduction; Loss and Damage; and SDGs, New Urban Agenda, and Voluntary Local Reviews
MeSH term explosion and author rank improve expert recommendations
No full textInformation overload is an often-cited phenomenon that reduces the productivity, efficiency and efficacy of scientists. One challenge for scientists is to find appropriate collaborators in their research. The literature describes various solutions to the problem of expertise location, but most current approaches do not appear to be very suitable for expert recommendations in biomedical research. In this study, we present the development and initial evaluation of a vector space model-based algorithm to calculate researcher similarity using four inputs: 1) MeSH terms of publications; 2) MeSH terms and author rank; 3) exploded MeSH terms; and 4) exploded MeSH terms and author rank. We developed and evaluated the algorithm using a data set of 17,525 authors and their 22,542 papers. On average, our algorithms correctly predicted 2.5 of the top 5/10 coauthors of individual scientists. Exploded MeSH and author rank outperformed all other algorithms in accuracy, followed closely by MeSH and author rank. Our results show that the accuracy of MeSH term-based matching can be enhanced with other metadata such as author rank
Reduction of Di-tert-Butyl Peroxide: Evidence for Nonadiabatic Dissociative Electron Transfer
No full textGoing Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
"Closing the R&D Gap, Evaluating the Sources of R&D Spending"
No full textBoth spending and tax policies have been implemented in the United States with the goal of stimulating private sector research and development (R&D). Karier questions whether current R&D policy, especially the research and experimentation tax credit, can contribute to closing the gap between nondefense expenditures on R&D in the United States and such expenditures in other countries, such as Japan and Germany. He also explores possible changes to our current R&D policy to make it more effective.
Right Ventricular Biomechanics in Pulmonary Hypertension
No full textPulmonary hypertension (PH) is a disease resulting in increased right ventricular (RV) afterload, myocardial hypertrophy and ventricular remodeling. RV failure remains the main cause of mortality for nearly 70% of PH patients, with 33-38% mortality rates 3 years post-diagnosis. RV biomechanics has been closely linked to physiological function. From a biomechanical perspective, pressure overloaded RV myocardium experiences increased wall thickness, fiber remodeling and increased stiffness to restore the cardiac output.
Despite the development of multiple therapeutics for management of PH, lung transplantation remains the only curative treatment. Moreover, age-related differences exist in the survival rates of PH patients and although the current evidence suggests an association between PH and aging, limited data exist on age-associated differences in RV biomechanical properties.
A major biomechanical remodeling event experienced by the pressure overloaded RV is the reorientation of myofibers forming the RV tissue, which results in altered biomechanical properties and function. However, RV wall thickness in human patients and large animal models complicates the study of fiber reorientation throughout the RV thickness, mainly due to the limited imaging depth of current modalities such as confocal or multi-photon microscopy.
In this work, we aimed to evaluate the effects of a novel dual-acting heart failure therapeutic (Sacubitril/Valsartan) on RV remodeling in PH. Additionally, we analyzed the effects of aging on RV structure and biomechanics. Moreover, an ultrasound image processing framework, coupled with computational models, was utilized to study the effects of different loading scenarios on the reorientation patterns of RV myofibers.
Our results showed that Sacubitril/Valsartan has the potential to prevent maladaptive RV remodeling in a pressure overload model via amelioration of RV pressure rise, hypertrophy, collagen and myofiber re-orientation as well as RV stiffening both at the tissue and myofiber-level. Additionally, our findings demonstrated the potential of healthy aging to modulate RV remodeling via increased peak pressures, cardiomyocyte loss, fiber reorientation, and altered collagen/myofiber stiffness. The developed ultrasound imaging framework effectively characterized the transmural orientation of RV myofibers. Computational models demonstrated that chronic pressure overload, but not solely an acute rise in pressures, results in kinematic shift of RV fibers towards the longitudinal direction
Dispelling the Myths Behind First-author Citation Counts
No full textWe 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
