No. of bitstreams: 0 Previous issue date: 2009-02-01 Dental fluorosis is a developmental disturbance of dental enamel, caused by successive exposures to high concentrations of fluoride during tooth development, leading to enamel with lower mineral content and increased porosity. The severity of dental flu…
The role of therapist and patient in-session behavior for treatment outcome in exposure-based cognitive behavioral therapy for panic disorder with ag…
2018
Objective There is a very limited amount of research on the relationship between therapist and patient in-session behavior and treatment outcome in cognitive behavioral therapy (CBT) for panic disorder with agoraphobia (PD/AG). Additionally, the findings tend to be inconclusive. This study investigates the association between therapist competence, adherence, patient interpersonal behavior, and therapeutic alliance and outcome in a low-control CBT setting by using comprehensive measures. Methods Twenty-six patients with PD/AG received 12 sessions of exposure-based CBT. With regard to the outcome, treatments were classified either as problematic or nonproblematic by means of distinct criteria…
Heritage and knowledge: apparatus, logic and strategies in the formation of heritage
2016
Heritage as a category reflects diverse political positions. All heritagisation processes imply the creation of hierarchies, selection, ranking, and categorization of what is worthy or unworthy of being heritage, and all heritage creation involves certain disciplinary processes that confer legitimacy. As a modern invention, heritage was built on two closely-related cornerstones: the distinction between nature and culture and the difference between normalized knowledge and marginal knowledge. As a result, refining processes were applied which became strategies to legitimise political domination. In this paper the constituent process of heritage creation and its links to normative knowledge a…
La motivación de los entrenadores deportivos: un estudio desde la teoría de la autodeterminación
2013
El objetivo del estudio consistió en analizar, en una muestra formada por 506 entrenadores, sus percepciones de: satisfacción de necesidades, percepción de utilidad, motivación autodeterminada, y promoción del bienestar de sus deportistas, así como las diferencias en función del sexo, edad y tipo de deporte. También se analizó si las relaciones entre las variables analizadas correspondían a los postulados de la Teoría de la Autodeterminación (TA) (Deci y Ryan, 1985a, b; 2000; Ryan y Deci, 2007). El análisis descriptivo indicó que los entrenadores en general obtuvieron altos niveles de satisfacción de necesidades, percepción de utilidad, motivación autodeterminada, y promoción del bienestar,…
Validez de instrumento para medir la competencia territorial. Matriz READI para la autoevaluación de territorios competentes
2021
El artículo presenta el diseño metodológico seguido para el análisis de la validez y fiabilidad de una matriz cuya finalidad es la de permitir a los territorios autoevaluar su grado de competencia potencial para la consecución de objetivos ligados al desarrollo local. Se ha seguido un diseño de estudio descriptivo de construcción de conceptos, dimensiones e indicadores y de verificación de escalas multidimensionales a través de análisis factorial y validez de constructo. El análisis cuantitativo realizado combinado con aportaciones cualitativas de personas expertas, concluye que la matriz es un instrumento válido y confiable para su cometido.
Design management capability and product innovation in SMEs
2013
[Purpose]: The aim of this paper is to present design management as a dynamic capability and to analyze its mediating role between organizational learning capability and product innovation performance in small and medium enterprises (SMEs). [Design/methodology/approach]: Structural equation modeling is used to test the research hypotheses based on data from the Italian and Spanish ceramic tile industries. The data are derived from the responses of 182 companies (50 percent of the target population) to a questionnaire addressed to Product Development Managers and Human Resource Managers. [Findings]: The results suggest that organizational learning capability enhances product innovation throu…
GW170817: Implications for the Stochastic Gravitational-Wave Background from Compact Binary Coalescences
2018
The LIGO Scientific and Virgo Collaborations have announced the first detection of gravitational waves from the coalescence of two neutron stars. The merger rate of binary neutron stars estimated from this event suggests that distant, unresolvable binary neutron stars create a significant astrophysical stochastic gravitational-wave background. The binary neutron star background will add to the background from binary black holes, increasing the amplitude of the total astrophysical background relative to previous expectations. In the Advanced LIGO-Virgo frequency band most sensitive to stochastic backgrounds (near 25 Hz), we predict a total astrophysical background with amplitude $\Omega_{\rm…
Critical assessment of ionization patterns and applications of ambient desorption/ionization mass spectrometry using FAPA-MS
2016
Ambient desorption/ionization mass spectrometry (MS) has gained growing interest during the last decade due to its high analytical performance and yet simplicity. Here, one of the recently developed ambient desorption/ionization MS sources, the flowing atmospheric-pressure afterglow (FAPA) source, was investigated in detail regarding background ions and typical ionization patterns in the positive as well as the negative ion mode for a variety of compound classes, comprising alkanes, alcohols, aldehydes, ketones, carboxylic acids, organic peroxides and alkaloids. A broad range of signals for adducts and losses was found, besides the usually emphasized detection of quasimolecular ions, i.e. […
A new interface to couple thin-layer chromatography with laser desorption/atmospheric pressure chemical ionization mass spectrometry for plate scanni…
2005
An interface to allow on-line qualitative and quantitative full-plate detection and analysis of compounds separated by thin-layer chromatography (TLC) is presented. A continuous wave diode laser is employed as a desorption source. Atmospheric pressure chemical ionization mass spectrometry ionizes and subsequently identifies the desorbed sample molecules. Besides direct laser desorption on untreated TLC plates, graphite particles were used as a matrix to couple in the laser power and improve the efficiency of desorption.
Measurement of nanoparticle mass distributions by laser desorption/ionization time-of-flight mass spectrometry.
2011
In this paper, access to the mass distribution analysis of nanoparticles is described based on laser desorption/ionization and time of flight mass spectrometry. Two examples are given, demonstrating the accurate mass distribution analysis of nanoparticles fabricated both ex situ and in situ during the laser-assisted desorption process. The potentials and the limitations of the method are discussed, with special emphasis on carbonaceous clusters and molecules.
