La radicalidad del mal banal
2002
El concepto de ‘banalidad del mal’ fue introducido por Hannah Arendt a fin de caracterizar una forma inédita de perversidad que ella vio encarnada en Adolf Eichmann y otros criminales nazis. Arendt consideraba que esa forma de perversidad estaba muy alejada de la noción de ‘mal radical’ que Kant había acuñado y la propia Arendt había empleado en trabajos anteriores. El objetivo principal del artículo es mostrar que hay más afinidades entre el mal radical kantiano y la banalidad del mal de lo que la propia Arendt reconoce. ‘Banality of evil’ was a concept introduced by Hannah Arendt in order to characterize a new form of wickedness embodied in people as Adolf Eichmann and others nazis crimin…
Clima motivacional percibido, motivación autodeterminada y autoestima en jóvenes deportistas mexicanos
2010
En el marco de la Teoría de las Metas de Logro (Ames, 1992; Dweck, 1999; Nicholls, 1989), y de la Teoría de la Autodeterminación (Deci y Ryan, 1985, 2000) en el presente trabajo se puso a prueba un modelo con la siguiente secuencia: Clima motivacional percibido (clima de implicación en la tarea y clima de implicación en el ego) ÞMotivación Autodeterminada Þ Autoestima. Además, se analizó si la motivación autodeterminada actuaba como mediadora entre cada una de las dos dimensiones del clima motivacional percibido (clima de implicación en la tarea y clima de implicación en el ego) y la autoestima. Participaron 651 deportistas juveniles mexicanos (Medad = 13,99; DT = 1,88), 330 chicas y 321 ch…
Electrodeposition and characterization of Mo oxide nanostructures
2015
Template electrodeposition has been used to grow uniform arrays of molybdenum oxide nanostructures in polycarbonate membrane. Several parameters have been investigated, like electrodeposition, time and solution pH. These parameters do not influence the nature of the deposit that always consists of mixed valence molybdenum oxides, whereas the nanostructure morphology changes with pH. In particular, at low pH (2.7), nanotubes are formed, whilst arrays of nanowires are obtained above pH 5.5. This change of morphology is likely due to H2 bubbles evolution during the electrochemical deposition, particularly occurring at low pH. It was found that fast removal of H2 bubbles through vigorous stirri…
Prediction of Specific TCR-Peptide Binding From Large Dictionaries of TCR-Peptide Pairs
2019
Abstract The T cell repertoire is composed of T cell receptors (TCR) selected by their cognate MHC-peptides and naive TCR that do not bind known peptides. While the task of distinguishing a peptide-binding TCR from a naive TCR unlikely to bind any peptide can be performed using sequence motifs, distinguishing between TCRs binding different peptides requires more advanced methods. Such a prediction is the key for using TCR repertoires as disease-specific biomarkers. We here used large scale TCR-peptide dictionaries with state-of-the-art natural language processing (NLP) methods to produce ERGO (pEptide tcR matchinG predictiOn), a highly specific classifier to predict which TCR binds to which…
De los corpúsculos de luz al efecto fotoeléctrico. Una propuesta didáctica con base en la discusión de modelos.
2010
Se presenta una propuesta de una unidad didáctica cuyo objetivo es analizar la evolución de los modelos de la radiación, generar una visión más adecuada sobre la ciencia y la construcción del conocimiento científico que la que suele ser común en alumnos y profesores y construir un modelo de la radiación más cercano a la visión científica actual, en el que las propiedades del modelo corpuscular y el ondulatorio se conjugan en un nuevo objeto cuántico con comportamiento dual. A través de cuatro actividades se analiza la secuencia de modelos propuestos a lo largo de la historia para explicar la na…
Application of Ge Nanowire for Two-Input Bistable Nanoelectromechanical Switch
2013
Recently, several research groups presented bistable two-terminal nanoelectromechanical switches based on individual single-clamped active element. All presented devices had one input electrode. Similar devices having two or more input electrodes have not been yet investigated. In this work we present the two-input bistable controlled nanoelectromechanical switch based on an individual single-clamped Ge nanowire. The switch is realised using in-situ SEM technique and operating due to balancing of electrostatic, adhesion and elastic forces. The operation conditions of the device are investigated and presented. The advantages and drawbacks of the device are discussed. DOI: http://dx.doi.org/1…
Photoelectrical Properties and Energetical Structure of Thin Films of Indandione Derivatives
2011
A sandwich type structure of two dimetilaminobenziliden-1,3-indandione (DMABI) derivatives placed between metal electrodes was made to investigate the photoelectrical properties of these derivatives. DMABI is an organic isolator with a wide energy gap and high quantum efficiency of the photogeneration, DMABI derivatives have received also considerable attention because of its large dipole moment and optical nonlinearities. Besides, since it is a photosensitive material, its use in solar systems is very promising. The energy gap of each material and combined system was observed from the spectral dependence of the quantum efficiency of the photoconductivity and results are compared with resul…
Flash infrared annealing as a cost-effective and low environmental impact processing method for planar perovskite solar cells
2019
Abstract For successful commercialization of perovskite solar cells, straightforward solutions in terms of environmental impact and economic feasibility are still required. Flash Infrared Annealing (FIRA) is a rapid method to fabricate perovskite solar cells with efficiencies >18% on simple, planar architecture, which allows a film synthesis in only 1.2 s, faster than the previous report based in a meso architecture and all of them without the usage of antisolvent. In this work, through a comparative study with the common lab-scale method, the so-called antisolvent (AS), the main photovoltaic parameters and working mechanisms obtained from impedance spectroscopy (IS) measurements show simil…
Siirtymätilassa : autoetnografinen tutkimus kirjoittajan matkasta proosan pariin
2020
Tarkastelen artikkelissa siirtymätilaa kahden eri kirjoittamisen lajin välillä autoetnografian keinoin. Aineistona on tutkimusprosessin ajan pitämäni työpäiväkirja, jota analysoin temaattisella sisällönanalyysilla. Siirtymätilan lisäksi olen kuvannut työpäiväkirjan merkitystä, havaintojen tekemistä ja työpäiväkirjassa välittyvää mielen näyttämöä. Tutkimus tuo keskusteluun yhden näkökulman siitä, missä mieli ja huomio askaroivat siirtymätilan aikana ja mikä helpottaa lajin muutosta ja itselle uudenlaiseen kirjoittamisen tilaan pääsemistä. peerReviewed
Cortical correlates of language perception : neuromagnetic studies in adults and children
2007
Kielen havaitsemisen päämääränä on ymmärtää kuullun tai luetun viestin sisältö. Itse havaitseminen on meille näennäisen vaivatonta. Puheen tunnistaminen ja lukeminen ovat kuitenkin tulos monimutkaisesta aivokuorella tapahtuvasta laskennasta, jonka lähtökohtana on silmän ja korvan vastaanottama fysikaalinen signaali.Tiina Parviainen tarkasteli väitöstutkimuksessaan kielen käsittelyn aivomekanismeja normaalisti lukevilla ja lukivaikeuksisilla aikuisilla sekä lukemaan opettelevilla lapsilla. Hän selvitti kirjoitetun ja puhutun kielen käsittelyyn liittyvää aktivaatioketjua aivoissa ja siinä esiintyviä eroja aikuisten ja lasten välillä. Kielen aivomekanismien kartoituksessa on keskeistä aktivaat…
