Suomen tiedontuotannon regiimi : yksi vai monta?
2021
Poliittisen talouden tutkimuksessa tapahtui 1990-luvulla niin kutsuttu ideakäänne. Viimeisen reilun vuosikymmenen aikana on alettu systemaattisesti tutkia ideoiden tuotantoa ja kanavointia poliittis-taloudelliseen päätöksentekoon. Vertailevan poliittisen talouden tutkimuksen piirissä on kehitetty tiedontuotannon regiimin teoria, joka tarkastelee tiedontuotannon institutionaalisia ja organisatorisia koneistoja, jotka tuottavat ideoita ja asiantuntijatietoa poliittis-taloudellista päätöksentekoa varten. Tämä artikkeli esittelee ja problematisoi tiedontuotannon regiimien tutkimusta. Artikkeli problematisoi tutkimuksen taustaoletusta regiimiin kuuluvien tiedontuottajien muodostaman organisaatio…
Tunable Superstructures of Dendronized Graphene Nanoribbons in Liquid Phase
2019
In this Communication, we report the first synthesis of structurally well-defined graphene nanoribbons (GNRs) functionalized with dendritic polymers. The resultant GNRs possess grafting ratios of 0.59-0.68 for the dendrons of different generations. Remarkably, the precise 3D branched conformation of the grafted dendrons affords the GNRs unprecedented 1D supramolecular self-assembly behavior in tetrahydrofuran (THF), yielding nanowires, helices and nanofibers depending on the dimension of the dendrons. The GNR superstructures in THF exhibit near-infrared absorption with maxima between 650 and 700 nm, yielding an optical bandgap of 1.2-1.3 eV. Ultrafast photoconductivity analyses unveil that …
Diseño y validación de un instrumento para evaluar la competencia "Aprender a aprender" en profesionales de la educación
2015
Desde la década de los años 90, la educación gira hacia el modelo orientado al desarrollo de competencias. Diversas aportaciones de gran calado (Delors, 1996; Eurydice, 2002; OCDE , 2005; Proyecto Tuning, 2007) se han ido constituyendo en referencias conceptuales para el diseño, desarrollo y organización de la Enseñanza y de la Educación. En este marco, el Espacio Europeo de Educación Superior ha incorporado esta orientación pedagógica, señalando la necesidad de abordar el desarrollo en las titulaciones universitarias de competencias generales y específicas. Se destaca como denominador común el hecho de que todas ellas implican preparar a la persona para aprender a aprender. El hecho de rec…
Structural changes induced by daily music listening in the recovering brain after middle cerebral artery stroke: a voxel-based morphometry study
2014
[Abstract.] Music is a highly complex and versatile stimulus for the brain that engages many temporal, frontal, parietal, cerebellar, and subcortical areas involved in auditory, cognitive, emotional, and motor processing. Regular musical activities have been shown to effectively enhance the structure and function of many brain areas, making music a potential tool also in neuro- logical rehabilitation. In our previous randomized controlled study, we found that listening to music on a daily basis can improve cognitive recovery and improve mood after an acute mid- dle cerebral artery stroke. Extending this study, a voxel-based morphometry (VBM) analysis utilizing cost function masking was perf…
Search for the neutral Higgs bosons of the Minimal Supersymmetric Standard Model in $pp$ collisions at $\sqrt{s}=7$ TeV with the ATLAS detector
2013
A search for neutral Higgs bosons of the Minimal Supersymmetric Standard Model (MSSM) is reported. The analysis is based on a sample of proton-proton collisions at a centre-of-mass energy of 7 TeV recorded with the ATLAS detector at the Large Hadron Collider. The data were recorded in 2011 and correspond to an integrated luminosity of 4.7 fb[superscript −1] to 4.8 fb[superscript −1]. Higgs boson decays into oppositely-charged muon or τ lepton pairs are considered for final states requiring either the presence or absence of b-jets. No statistically significant excess over the expected background is observed and exclusion limits at the 95% confidence level are derived. The exclusion limits ar…
Strong enhancement of superconductivity at high pressures within the charge-density-wave states of 2H-TaS 2 and 2H-TaSe 2
2016
We present measurements of the superconducting and charge density wave critical temperatures (Tc and TCDW) as a function of pressure in the transition metal dichalchogenides 2H-TaSe2 and 2H-TaS2. Resistance and susceptibility measurements show that Tc increases from temperatures below 1 K up to 8.5 K at 9.5 GPa in 2H-TaS2 and 8.2 K at 23 GPa in 2H-TaSe2. We observe a kink in the pressure dependence of TCDW at about 4 GPa that we attribute to the lock-in transition from incommensurate CDW to commensurate CDW. Above this pressure, the commensurate TCDW slowly decreases coexisting with superconductivity within our full pressure range.
