Multifunctionality: Epistemic diversity and concept oriented research clusters
2008
International audience; This paper provides a mapping of the different uses of the word multifunctionality. To explore the diversity of meanings and interpretations, a comparative analysis was conducted through five national case studies in France, the Netherlands, Poland, Spain and Switzerland. The analysis conducted at national level makes it possible to identify eight Concept Oriented Research Clusters (CORCs), based on a relative homogeneity in the research practices, in the research questions addressed, in the concepts used or discussed by scientists to lead their work and in the scientific disciplines, the stream of thought or possibly the epistemic community researchers belong to.

BCG Mass Evolution in Cosmological Hydro-Simulations
2018
We analyze the stellar growth of Brightest Cluster Galaxies (BCGs) produced by cosmological zoom-in hydrodynamical simulations of the formation of massive galaxy clusters. The evolution of the stellar mass content is studied considering different apertures, and tracking backwards either the main progenitor of the $z=0$ BCG or that of the cluster hosting the BCG at $z=0$. Both methods lead to similar results up to $z \simeq 1.5$. The simulated BCGs masses at $z=0$ are in agreement with recent observations. In the redshift interval from $z=1$ to $z=0$ we find growth factors 1.3, 1.6 and 3.6 for stellar masses within 30kpc, 50kpc and 10% of $R_{500}$ respectively. The first two factors, and in…
Lotus tenuis x L. corniculatus interspecific hybridization as a means to breed bloat-safe pastures and gain insight into the genetic control of proan…
2014
Background: Proanthocyanidins (PAs) are secondary metabolites that strongly affect plant quality traits. The concentration and the structure of these metabolites influence the palatability and nutritional value of forage legumes. Hence, modulating PAs in the leaves of forage legumes is of paramount relevance for forage breeders worldwide. The lack of genetic variation in the leaf PA trait within the most important forage species and the difficulties in engineering this pathway via the ectopic expression of regulatory genes, prompted us to pursue alternative strategies to enhance this trait in forage legumes of agronomic interest. The Lotus genus includes forage species which accumulate PAs …
Anomalous Slowdown of Polymer Detachment Dynamics on Carbon Nanotubes
2019
The "wrapping" of polymer chains on the surface of carbon nanotubes allows one to obtain multifunctional hybrid materials with unique properties for a wide range of applications in biomedicine, electronics, nanocomposites, biosensors, and solar cell technologies. We study by means of molecular dynamics simulations the force-assisted desorption kinetics of a polymer from the surface of a carbon nanotube. We find that, due to the geometric coupling between the adsorbing surface and the conformation of the macromolecule, the process of desorption slows down dramatically upon increasing the windings around the nanotube. This behavior can be rationalized in terms of an overdamped dynamics with a…
Two-loop QED corrections to the Altarelli-Parisi splitting functions
2016
We compute the two-loop QED corrections to the Altarelli-Parisi (AP) splitting functions by using a deconstructive algorithmic Abelianization of the well-known NLO QCD corrections. We present explicit results for the full set of splitting kernels in a basis that includes the leptonic distribution functions that, starting from this order in the QED coupling, couple to the partonic densities. Finally, we perform a phenomenological analysis of the impact of these corrections in the splitting functions.
Combining data from high-energy p p -reactions and neutrinoless double-beta decay: Limits on the mass of the right-handed boson
2016
From the recently established lower-limits on the nonobservability of the neutrinoless double-beta decay of 76Ge (GERDA collaboration) and 136Xe (EXO-200 and KamLAND-Zen collaborations), combined with the ATLAS and CMS data, we extract limits for the left-right (LR) mixing angle, of the SU(2)L ×SU(2)R electroweak Hamiltonian. For the theoretical analysis, which is a model dependent, we have adopted a minimal extension of the Standard Model (SM) of Electroweak Interactions belonging to the SU(2)L ×SU(2)R representation. The nuclear-structure input of the analysis consists of a set of matrix elements and phase-space factors, and the experimental lower-limits for the half-lives. The other inpu…
Global analysis of fragmentation functions for eta mesons
2011
Fragmentation functions for eta mesons are extracted at next-to-leading order accuracy of QCD in a global analysis of data taken in electron-positron annihilation and proton-proton scattering experiments. The obtained parametrization is in good agreement with all data sets analyzed and can be utilized, for instance, in future studies of double-spin asymmetries for single-inclusive eta production. The Lagrange multiplier technique is used to estimate the uncertainties of the fragmentation functions and to assess the role of the different data sets in constraining them.
Miksi työmarkkinoiden ja kielikoulutuksen tarpeet eivät kohtaa?
2012
Luopumalla eri kielten lokeroajattelusta ja omaksumalla uudenlainen näkemys kielten opiskeluun tuotettaisiin suurempaa kielitaitohyötyä niin työelämässä kuin sen ulkopuolellakin. Language for Jobs työryhmä on etsinyt ratkaisuja kielitaitotarpeiden ja kielikoulutuksen tarjonnan kohtaamisen ongelmiin.
Suomalainen korkeakoulutus kriisissä?
2005
”Voi liioittelematta sanoa, että kaikki suomalaiset yliopistot kuuluvat ’maailmanluokan’ yliopistoihin. Mistä siis nousee Jorma Rantasen ja Anne Brunilan raporteissa esitetty ehdotus luoda Suomeen muutama ’maailmanluokan’ yliopisto, joiden ohella olisi kansallisen tai maakunnallisen tason opinahjoja? Kysymys näyttäisi olevan koulutuspolitiikan suunnan muutosyrityksistä kohti markkinatalouden kilpailuun perustuvaa arvomaailmaa”, kirjoittaa professori Jussi Välimaa.
Kotoutumiskoulutuksen opetussuunnitelman perusteet kuvaa tavoitettaan osallisuutta epämääräisesti ja kapeasti
2023
Kotoutumiskoulutuksen uudessa perusteasiakirjassa korostuu osallisuuden käsite. Se jää kuitenkin määrittelemättä: osallisuuteen viitataan sekä kapearajaisesti työmarkkinaosallisuutena että epäsuorasti niin, että käsitteen varsinainen merkitys jää avoimeksi. Tutkimuskirjallisuudessa osallisuus edellyttää laaja-alaista sosiaalis-yhteiskunnallista kuulumista ja yhdenvertaisuutta. nonPeerReviewed
