Why have consumers opposed, postponed, and rejected Innovations during a pandemic? A Study of mobile payment Innovations
2021
The highly infectious nature of the COVID-19 virus has made the use of contactless payment methods a health exigency. Yet, consumers are resisting using mobile payments (m-payments) during the pandemic, a confounding behavior that needs to be better understood. The present study explicates this behavior by examining consumer resistance to m-payments during the COVID-19 pandemic. In addition, it provides more granular findings by measuring three levels of resistance/non-adoption, namely, postponement, opposition, and rejection. In this way, the study adds depth to the literature, which has largely examined resistance at an aggregate level to yield generic findings. Toward this end, the study…
Crises and Social Media: A Metastudy on Pertinent Research and Practice
2014
Aiming to structure the academic debate and to demonstrate practical use cases of social media in crisis communication, we present in this metastudy the disciplinary embedment, topical foci, challenges, and research gaps in the literature and application of social media in crisis communication. In particular, our research questions address the characteristics and features of the academic discourse and examine the role of grant givers in steering research foci, as well as the value of research outcomes for crisis communication practice. Therefore, we analyze pertinent academic articles and research projects from the past decade and provide an excursus on the actors and social media communica…
Derechos humanos y virtudes fundamentales
2013
Al establecer los derechos humanos dentro de un constitucionalismo democrático en vez de hacerlo en la verdad de la persona, los legalismos entran en un círculo infinito. Entonces, es necesario asentarlos en un fundamento pre-legal, previo a toda deliberación que incluya las virtudes clásicas de la coexistencia humana que hacen posible cualquier proceso democrático. Aunque este documento se centra básicamente en la justicia, el éxito, el coraje y la templanza como los goznes de toda virtud, también se refiere al valor del compañerismo, la simplicidad, la austeridad, la lealtad y la confianza hacia otros. Pero todo este marco axiológico nos obliga naturalmente a mirar hacia la familia, donde…
Estereotipos corporales en las imágenes de los libros de texto de inglés
2017
La educación es el camino para generar conductas positivas en niños y niñas y promover un ambiente social y armónico, así como respeto de los valores éticos y democráticos de nuestra sociedad. Un valor ético y democrático importante es la actitud no discriminante, sin prejuicios y no estereotipada. El objetivo del presente estudio fue analizar la frecuencia de ocurrencia de posibles estereotipos ligados a género, edad, raza y somatotipo presentes en las imágenes de los libros de texto de inglés del tercer ciclo de Primaria del sistema educativo español. Para ello, se ha realizado un estudio descriptivo con 1774 imágenes de 5 colecciones de libros de texto de la asignatura de inglés (Bugs Wo…
Ecological Indicator Values for Europe (EIVE) 1.0
2023
Aims: To develop a consistent ecological indicator value system for Europe for five of the main plant niche dimensions: soil moisture (M), soil nitrogen (N), soil reaction (R), light (L) and temperature (T). Study area: Europe (and closely adjacent regions). Methods: We identified 31 indicator value systems for vascular plants in Europe that contained assessments on at least one of the five aforementioned niche dimensions. We rescaled the indicator values of each dimension to a continuous scale, in which 0 represents the minimum and 10 the maximum value present in Europe. Taxon names were harmonised to the Euro+Med Plantbase. For each of the five dimensions, we calculated European values fo…

Ellenberg-type indicator values for European vascular plant species
2022
This is a dataset of Ellenberg-type indicator values for European vascular plant species described in this article: Tichý L., Axmanová I., Dengler J., Guarino R., Jansen F., Midolo G., Nobis M.P., Van Meerbeek K., Aćić S., Attorre F., Bergmeier E., Biurrun I., Bonari G., Bruelheide H., Campos J.A., Čarni A., Chiarucci A., Ćuk M., Ćušterevska M., Didukh Y., Dítě D., Dítě Z., Dziuba T., Fanelli G., Fernández-Pascual E., Garbolino E., Gavilán R.G., Gégout J.-C., Graf U., Güler B., Hájek M., Hennekens S.M., Jandt U., Jašková A., Jiménez-Alfaro B., Julve P., Kambach S., Karger D.N., Karrer G., Kavgacı A., Knollová I., Kuzemko A., Küzmič F., Landucci F., Lengyel A., Lenoir J., Marcenò C., Moeslun…
Distribution maps of vegetation alliances in Europe
2022
Aim The first comprehensive checklist of European phytosociological alliances, orders and classes (EuroVegChecklist) was published by Mucina et al. (2016, Applied Vegetation Science, 19 (Suppl. 1), 3-264). However, this checklist did not contain detailed information on the distribution of individual vegetation types. Here we provide the first maps of all alliances in Europe. Location Europe, Greenland, Canary Islands, Madeira, Azores, Cyprus and the Caucasus countries. Methods We collected data on the occurrence of phytosociological alliances in European countries and regions from literature and vegetation-plot databases. We interpreted and complemented these data using the expert knowledge…
The Potsdam Open Source Radio Interferometry Tool (PORT)
2021
The Potsdam Open Source Radio Interferometry Tool (PORT) is the very long baseline interferometry (VLBI) analysis software developed and maintained at the GFZ German Research Centre for Geosciences. Chiefly, PORT is tasked with the timely processing of VLBI sessions and post-processing activities supporting the generation of celestial and terrestrial reference frames. In addition, it serves as a framework for research and development within the GFZ's VLBI working group and is part of the tool set employed in educating young researchers. Starting out from VLBI group delays, PORT estimates station and radio sources positions, as well as Earth orientation parameters, tropospheric parameters, a…
Paenibacillus larvae Chitin-Degrading Protein PlCBP49 Is a Key Virulence Factor in American Foulbrood of Honey Bees
2014
Paenibacillus larvae, the etiological agent of the globally occurring epizootic American Foulbrood (AFB) of honey bees, causes intestinal infections in honey bee larvae which develop into systemic infections inevitably leading to larval death. Massive brood mortality might eventually lead to collapse of the entire colony. Molecular mechanisms of host-microbe interactions in this system and of differences in virulence between P. larvae genotypes are poorly understood. Recently, it was demonstrated that the degradation of the peritrophic matrix lining the midgut epithelium is a key step in pathogenesis of P. larvae infections. Here, we present the isolation and identification of PlCBP49, a mo…
