Optical method for predicting the composition of self-assembled monolayers of mixed thiols on surfaces coated with silver nanoparticles.
2012
With a simple optical method, based on UV-vis absorption spectra on glass slides, it is possible to predict the composition of self-assembled monolayers of mixed thiols, grafted on monolayers of silver nanoparticles. Glass slides are modified with the layer-by-layer technique, first forming a monolayer of mercaptopropyltrimethoxysilane, then grafting a monolayer of silver nanoparticles on it. These surfaces are further coated by single or mixed thiol monolayers, by dipping the slides in toluene solutions of the chosen thiols. Exchange constants are calculated for the competitive deposition between the colorless 1-dodecanethiol or PEG5000 thiol and BDP-SH, with the latter being a thiol-beari…
The need to grow, learn and develop – how does management affect motivation for professional development?
2018
This article argues that knowledge management and social recognition is important for organisational learning and professional self-esteem in academic libraries. An anonymous survey was issued in 2016 to investigate how library staff’s self-esteem is affected by how they experience their management’s view and overview of their knowledge. The need for what Axel Honneth refers to as social recognition will also be discussed as an important part of how professional self-esteem and work satisfaction is experienced and further how this affects motivation to participate in professional development.
The Effects of Low-frequency Vibration on Aligner Treatment Duration: A Clinical Trial
2021
Objectives: The aim of this study was to investigate the effectiveness of an orthodontic tooth movement acceleration device (AcceleDent, OrthoAccel Technologies, Houston, Texas) when used during an aligner treatment. Materials and Methods: Adult patients who began an aligner treatment (Lineo, Micerium Lab, Avegno, Italy) were allocated to two treatment groups. The first one (Group A), with a 7-day aligner change regimen, used the AcceleDent device for 20 min per day, whereas the second one (Group B) changed the aligners every 14 days and did not use any device. The registered outcomes were the possibility of completing the treatment, the number of aligners needed and treatment duration in t…
Tratamiento crítico de la información de estudiantes universitarios desde los entornos personales de aprendizaje
2019
Resumen Partiendo del Proyecto CAPPLE (financiado por el Ministerio español de Economía y Competitividad), en este artículo identificamos las estrategias y las herramientas en red utilizadas por 2054 estudiantes universitarios españoles de último curso para efectuar un tratamiento crítico de la información y gestionar su proceso de aprendizaje. Desde un diseño de investigación no experimental de tipo exploratorio, se ha utilizado un cuestionario validado a través de un triple procedimiento (juicio de expertos, entrevistas cognitivas y estudio piloto) para recoger datos de 75 universidades en España. Los resultados muestran que los futuros profesionales son conscientes de la necesidad de con…
Museos para todos: la traducción e interpretación para entornos multimodales como herramienta de accesibilidad universal
2012
This article is the English version of “Museos para todos. La traducción e interpretación para entornos multimodales como herramienta de accesibilidad universal” by Catalina Jiménez Hurtado, Claudia Seibel & Silvia Soler Gallego. It was not published on the print version of MonTI for reasons of space. The online version of MonTI does not suffer from these limitations, and this is our way of promoting plurilingualism. Audiovisual Translation (AVT) has a scientific responsibility to develop analytical methodologies for the textual phenomenon of multimodality, and for the translation strategies associated with it. At the same time, it should aim to provide studies of universal accessibility wi…
Museums for all: translation and interpreting for multimodal spaces as a tool for universal accessibility
2012
Audiovisual Translation (AVT) has a scientific responsibility to develop analytical methodologies for the textual phenomenon of multimodality, and for the translation strategies associated with it. At the same time, it should aim to provide studies of universal accessibility with a powerful tool for facilitating access to knowledge. This article offers some reflections on the theoretical foundations of AVT and considers how these are projected in the creation of new professional profiles, with specific application to universal accessibility in the museums. La Traducción Audiovisual (TAV) tiene la responsabilidad científica de desarrollar metodologías de análisis para el fenómeno textual de …
Using Crowdsourcing to Overcome Barriers to Women Entrepreneurship
2015
This chapter presents crowdsourcing as a novel way of overcoming barriers facing women entrepreneurs, offering alternatives to conventional solutions. The study analyzes three barriers to women entrepreneurship: access to financing, access to specific management knowledge, and access to information and communication technologies (ICTs). For each barrier, a different form of crowdsourcing is proposed: crowdfunding, crowd wisdom, and crowdfunded media, respectively. Using these crowdsourcing tools, women entrepreneurs can overcome major difficulties when starting businesses.
Improve Your Social Network and Have the Advantage in the Employment Seeking Process
2021
Human resource management uses social networks to identify new employees. This research investigates if people use social networks to identify employment opportunities and how they improve their networks to get easier and quicker access to information and resources. Researchers worldwide devote their attention to different aspects of identification of new employees via social networks. The authors of the paper have done empirical research based on an online survey with 298 respondents, and the data obtained from the survey has been analysed using various statistical tools. The number of suitable candidates for employment is decreasing and companies need knowledge about the employment seekin…
Impacto de la Sociedad del Conocimiento en la universidad y en la comunicación científica
2014
A la largo de las dos últimas décadas y como resultado de la introducción y uso intensivo de las tecnologías de la información y del conocimiento en general y de internet en particular, la universidad esta viviendo un proceso de transformación complejo que afecta a sus estructuras académicas y organizativas así como también a su concepción de metodología docente. Las TIC han evidenciado la necesidad de establecer estrategias de coherencia institucional en su uso y aplicación, así como la posibilidad de ampliar los ámbitos de acción institucional y el acceso masivo a la formación superior. Y todo ello pone de manifiesto el cambio existente de un modelo de formación basado en la transmisión d…
Oltrepassare le soglie per accedere alla conoscenza del patrimonio
2021
Rendere accessibili i monumenti, come le opere maggiori e minori, che costituiscono il nostro patrimonio culturale significa dotarli di apposite soglie per oltrepassare quegli sbarramenti determinati dalla presenza di barriere sia fisiche sia culturali. Se per il superamento delle prime si interviene con interventi strutturali e architettonici che necessariamente devono essere gestiti da esperti di restauro, per il superamento delle barriere culturali entra in azione la disciplina del design della comunicazione visiva e con essa i designer in grado di adottare i corretti registri di traduzione dei contenuti in forme visuali di modo che questi possano essere fruiti da un pubblico ampio, in c…
