Highly cited educational technology journal articles: A descriptive and critical analysis
2022
Citations are valuable capital in the academy as the number of citations is the most frequently used indicator in evaluating the quality of papers, journals, researchers, and universities. Thus, the characteristics of highly cited articles (HCA) have become a common research topic but the approach has been mainly descriptive with no profound critical reflection of what kind of research is cited, where the research is from, where the research is published, and what do these things mean for edtech research. This paper contributes to this need by providing a descriptive and critical analysis of 200 highly cited articles from 10 edtech journals. To summarize the key findings, a ‘typical’ edtech…
Liberalism, how many divisions?
2022
Liberalism is a very broad political family which, if taken in the broadest sense, brings together authors with diverse positions whose only common point is their attachment to freedom. Therefore, to find one’s way around in this political family, it is essential to establish classification criteria. There are many possibilities: Liberals can be classified by nationality, by period, by preferred field of interest (economic liberalism, political liberalism), etc. This article proposes to classify them following two criteria, the conception of freedom on the one hand, and the utilitarian or jusnaturalist basis of the attachment to freedom on the other. These two criteria generate an operation…
The ATXN1 and TRIM31 genes are related to intelligence in an ADHD background: evidence from a large collaborative study totaling 4,963 subjects
2010
Contains fulltext : 96400.pdf (Publisher’s version ) (Closed access) Intelligence is a highly heritable trait for which it has proven difficult to identify the actual genes. In the past decade, five whole-genome linkage scans have suggested genomic regions important to human intelligence; however, so far none of the responsible genes or variants in those regions have been identified. Apart from these regions, a handful of candidate genes have been identified, although most of these are in need of replication. The recent growth in publicly available data sets that contain both whole genome association data and a wealth of phenotypic data, serves as an excellent resource for fine mapping and …

Can Money buy Love? : The Impact of the Cohesion Policy of the European Union on European Identity
2019
Master's thesis Innovative governance and public management ME523 - University of Agder 2019 This Master thesis explores the relationship between Cohesion policies of the EU and European identity. After first describing the history and context of Cohesion policies of the EU, the literature on European identity studies is reviewed. This discussion develops an economic utilitarian argument, that citizens in Europe develop their identification with the EU partly on rational considerations, and that the added quality of life provided by investments of the EU would positively influence their European identity. This effect is expected to be different throughout European regions.The hypothesesare …
An Early Stage Researcher's Primer on Systems Medicine Terminology
2021
Background: Systems Medicine is a novel approach to medicine, that is, an interdisciplinary field that considers the human body as a system, composed of multiple parts and of complex relationships at multiple levels, and further integrated into an environment. Exploring Systems Medicine implies understanding and combining concepts coming from diametral different fields, including medicine, biology, statistics, modeling and simulation, and data science. Such heterogeneity leads to semantic issues, which may slow down implementation and fruitful interaction between these highly diverse fields. Methods: In this review, we collect and explain more than100 terms related to Systems Medicine. Thes…
Cyclobutane Pyrimidine Photodimerization of DNA/RNA Nucleobases in the Triplet State
2010
The photoinduced formation of cyclobutane pyrimidine dimers in the triplet excited state of the DNA/RNA pyrimidine nucleobases pairs has been studied at the CASPT2 level of theory. A stepwise mechanism through the triplet state of the homodimer is proposed for the pairs of nucleobases cytosine, thymine, and uracil involving a singlet−triplet crossing intermediary structure of biradical character representing the most favorable triplet state conformation of the nucleobases as found in the DNA environment. The efficiency of the mechanism will be modulated by two factors: the effectiveness of the triplet−triplet energy transfer process from a donor photosensitizer molecule, which relates to th…
Disease dispersion as a spatial interaction: The case of Flavescence Dorée
2020
International audience; Flavescence dorée is a serious and incurable vine disease transmitted by an insect vector. Focusing on its spatial diffusion and on its control with pesticides, this paper investigates the private strategies of wine producers and their socially optimal counterparts. The socially optimal regulation has to address two externalities regarding private treatment decisions: (a) the insufficient consideration of collective benefits from controlling the vector populations; (b) the failure to take into account environmental damage related to pesticide application. The probability of infection is estimated on French data from a spatial econometric specification. Three alternat…
Crystal structure of 2-{[1-(2-methyl-5-nitro-1H-imidazol-1-yl)propan-2-yloxy]carbonyl}benzoic acid
2014
In the title compound, C15H15N3O6, the dihedral angle between the planes of the benzene and imidazole rings is 34.93 (10)°. An intramolecular C—H...O hydrogen bond is observed. In the crystal, O—H...N hydrogen bonds link the molecules into chains parallel to thecaxis.
Crystal structure of 3-mesityl-1-[(pyridin-2-yl)methyl]-3,4,5,6-tetrahydropyrimidin-1-ium bromide monohydrate
2015
In the title hydrated salt, C19H24N3+·Br−·H2O, the values of the N—C bond lengths within the tetrahydropyrimidinium ring indicate delocalization of the N=C double bond. In the cation, the dihedral angle formed by the pyridine and benzene rings is 14.97 (12)°. In the crystal, ions and water molecules are linked by O—H...Br, O—H...N, C—H...Br and C—H...O hydrogen bonds into chains running parallel to thebaxis.
