A genome-wide association study identifies Arabidopsis thaliana genes that contribute to differences in the outcome of infection with two Turnip mosa…

Viruses lie in a continuum between generalism and specialism depending on their ability to infect more or less hosts. While generalists are able to successfully infect a wide variety of hosts, specialists are limited to one or a few. Even though generalists seem to gain an advantage due to their wide host range, they usually pay a pleiotropic fitness cost within each host. On the contrary, a specialist has maximal fitness within its own host. A relevant yet poorly explored question is whether viruses differ in the way they interact with their hosts’ gene expression depending on their degree of specialization. Using a genome-wide association study approach, we have identified host genes whos…
Non-profit entities between generalistic vs. specialistic approaches on a systematics of levels of definitions and classifications
2012
This paper starts from the absence of a theory of Non-Profit Entities (NPE)in proper accounting or 'business economics' approaches. Accounting was traditionally developed by and for firms and is only roughly approaching the non-profit dominium. In doing so, we experience either an excessive generalism or excessive specialism. Hence, we seek a multi-level setting of the problem: general properties or 'characteristics' for entities in general, special properties or 'characterisations' for NPEs, and further properties of the main classes of NPEs. The chief outcome is the definition of based on the production of 'social' value and a further classification between NPOs and 'social' firms and, li…
Exposing the structure of an Arctic food web
2015
15 pages; International audience; How food webs are structured has major implications for their stability and dynamics. While poorly studied to date, arctic food webs are commonly assumed to be simple in structure, with few links per species. If this is the case, then different parts of the web may be weakly connected to each other, with populations and species united by only a low number of links. We provide the first highly resolved description of trophic link structure for a large part of a high-arctic food web. For this purpose, we apply a combination of recent techniques to describing the links between three predator guilds (insectivorous birds, spiders, and lepidopteran parasitoids) a…
Nonlinearities in plant RNA virus fitness
2012
Una de las mayores amenazas tanto para la salud humana y animal, como para la agronomía es la emergencia de nuevas enfermedades infecciosas, la mayoría de las cuales están causadas por los virus de RNA. La emergencia viral es un problema complejo que consista en la adquisición de la variación genética, por mutación o recombinación, dentro de la población viral en el huésped reservorio la cual podría facilitar la capacidad de infectar de manera eficiente nuevos huéspedes. Los virus de RNA presentan a una evolucionabilidad extraordinaria por sus grandes tamaños poblacionales, cortos tiempos de generación y altas tasas de mutación y recombinación. Comprender los mecanismos evolutivos que podrí…

“Generalist” Journals between Dissemination of Economics and Regime Propaganda
2019
Early in the 20th, generalist journals – a kind of press which had its major diffusion in the nineteenth century – continue to accommodate the contributions of economists offering a specific debating space. However, with the affirmation of fascist ideology, generalist periodicals progressively ceased to exist or to host economists’ articles. Thus, the main object of this research consists in clarifying what could be intended by “generalism” and in relation to which events and ideological pressures it disappeared as a different way to do journalism in a dialectic interplay with specialization. The paper reviews the panorama of generalist journals focusing on the impact of the Fascist regime …
Ripensare l'azienda: una prospettiva unitarista
2009
Molti dei piú avveduti ambienti scientifici, culturali, professionali, editoriali e persino politico-istituzionali auspicano da tempo il superamento di ogni contrapposizione artificiosa tra le cosiddette conoscenze scientifiche ed umanistiche, nonché fra numerose branche delle une e delle altre, alla quale hanno concorso, per speculari ma convergenti ragioni, sia lo specialismo sia il generalismo, intesi come ideologie e prassi, rispettivamente, della specializzazione e della generalizzazione nella conoscenza. Il presente scritto, nel punto 1 e nel punto 2, esplicita criticamente le principali ragioni di ordine generale che suggeriscono di concorrere al superamento in senso unitarista delle…
