Transition vers des systèmes agricole et agroalimentaire durables : quelle place et qualification pour les légumineuses à graines ?
2017
Cet article propose une analyse historique du processus de verrouillage du système agroalimentaire en défaveur des légumineuses à graines, à l’aune des théories évolutionnistes. Plusieurs mécanismes d’autorenforcement permettent de comprendre pourquoi ces espèces sont de moins en moins cultivées en France face à un système agro-industriel qui s’est spécialisé en faveur des céréales, favorisant à l’amont l’usage d’engrais azotés de synthèse et limitant à l’aval les investissements pour les légumineuses en alimentation humaine. Cet article s’interroge alors sur les perspectives de déverrouillage.
Effect of cactus pear cultivation after Mediterranean maquis on soil carbon stock, δ13C spatial distribution and root turnover
2014
Abstract Mediterranean ecosystems are characterized by nearly complete replacement of natural vegetation by intensive croplands and orchards leading to strong soil degradation. Organic carbon is usually accumulated in soils under maquis leading to partial regeneration of fertility for future agricultural use. The aim of this work was to investigate the effect of land use change from maquis to agriculture on soil organic carbon (SOC) stock and its spatial distribution in a Mediterranean system. Three Mediterranean land use systems (seminatural vegetation, cactus pear crop and olive grove) were selected in Sicily and analysed for soil C stocks and their δ13C. Total SOC and δ13C were measured …
El 20-N o el azar en la Historia
2007
El azar, ese mismo vector que había hecho caer en la misma jornada a José Antonio Primo de Rivera y Durruti en nuestra guerra civil, tenía reservada una sarcástica mueca. Ocurrió el 20 de noviembre de 39 años más tarde, cuando aquéllos que tiraban los hilos de la escuálida vida de Francisco Franco decidieron (el los mismos sabrán, o quizá no, por qué) desconectar los débiles cables que lo ataban a la tierra . Barrieron así ritos y mitos. O tal vez no. Porque los mitos algo tienen de caprichoso: ora resisten las más briosas tempestades, ora se dejan llevar por suaves brisas. ¿Azar o necesidad? El texto compara los sepelios de los dos héroes de acuerdo con los códigos establecidos en el culto…
Hronotops A. Manfeldes romānā “Vilcēni”, A. Jundzes romānā “Sarkanais dzīvsudrabs” un J. Joņeva romānā “Jelgava 94”
2022
Maģistra darba “Hronotops A. Manfeldes romānā “Vilcēni”, A. Jundzes romānā “Sarkanais dzīvsudrabs” un J. Joņeva romānā “Jelgava 94” mērķis ir raksturot un analizēt fiktīvo romānu 20. gadsimta 90. gadu laiktelpu Latvijā un citus ar to saistītus literāros hronotopus. Darba teorētiskajā daļā sniegts hronotopa teorētiskais ieskats, ieskats semiotiskajā un naratoloģijas pētniecības metodē; aplūkota hronotopa un romāna saistība; ieskats romānu recepcijā kritikā; sniegts ieskats kultūrvēsturiskajā situācijā un pilsētas laiktelpā. Pētījuma praktiskajā daļā tiek analizēts 20. gadsimta 90. gadu hronotops romānos caur naratīvu un kā tas atklājas caur dažādām semiotiskajām zīmēm pilsētvidē.
The Performative University: ‘Targets’, ‘Terror’ and ‘Taking Back Freedom’ in Academia
2020
The file attached to this record is the author's final peer reviewed version. The Publisher's final version can be found by following the DOI link. This special issue assembles eight papers which provide insights into the working lives of early career to more senior academics, from several different countries. The first common theme which emerges is around the predominance of ‘targets’, enacting aspects of quantification and the ideal of perfect control and fabrication. The second theme is about the ensuing precarious evocation of ‘terror’ impacting on mental well-being, albeit enacted in diverse ways. Furthermore, several papers highlight a particular type of response, beyond complicity to…
GRAd-COV2, a gorilla adenovirus-based candidate vaccine against COVID-19, is safe and immunogenic in younger and older adults
2022
International audience; Safe and effective vaccines against coronavirus disease 2019 (COVID-19) are essential for ending the ongoing pandemic. Although impressive progress has been made with several COVID-19 vaccines already approved, it is clear that those developed so far cannot meet the global vaccine demand alone. We describe a COVID-19 vaccine based on a replication-defective gorilla adenovirus expressing the stabilized prefusion severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike protein named GRAd-COV2. We assessed the safety and immunogenicity of a single-dose regimen of this vaccine in healthy younger and older adults to select the appropriate dose for each age group…
Nanotechnology against COVID-19: Immunization, diagnostic and therapeutic studies.
2021
The emergence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in early 2020 soon led to the global pandemic of Coronavirus Disease 2019 (COVID-19). Since then, the clinical and scientific communities have been closely collaborating to develop effective strategies for controlling the ongoing pandemic. The game-changing fields of recent years, nanotechnology and nanomedicine have the potential to not only design new approaches, but also to improve existing methods for the fight against COVID-19. Nanomaterials can be used in the development of highly efficient, reusable personal protective equipment, and antiviral nano-coatings in public settings could prevent the spread of SAR…
Effects of the COVID-19 Pandemic on Sports Entrepreneurship
2020
Sports entrepreneurship has been considered an important part of sports organisations when overcoming crisis situations. The aim of this study is to determine the impact of the crisis derived from COVID-19 on sports entrepreneurship and whether there are differences in the prediction of entrepreneurship on service quality in non-profit sports clubs. To this end, 145 sports clubs were analysed before and after the outbreak of the virus in society. Paired sample-t tests were carried out to determine the differences in variables studied before (Time I) and after (Time II) the COVID-19 outbreak, and correlations and hierarchical linear regressions were used to analyse the relationship between t…
Creativity and Innovation in Technology-Mediated Journalistic Work : Mapping out Enablers and Constraints
2020
This qualitative study examines creativity and innovation in dispersed, journalistic teams. Specifically, we study the factors enabling and constraining creativity and innovation in journalistic work in technology-mediated settings and explore how technology shapes these phenomena in dispersed journalistic teams. The study is motivated by the media industry’s heightened need for creativity and innovation as well as the changing nature of working life where an increasing amount of work is done via information and communication technologies. By closely examining two journalistic teams and their idea sharing and development processes, this study finds that successful creative work and innovati…
