Ultra-thin films of alternating semi-interpenetrating layers of a conducting polymer with thermosetting phenolic resins for sensor application

In this work a new method for crosslinking ultra-thin films with potential applications in sensor systems is proposed. The films were produced by layer-by-layer (LbL) assembly using a conducting polymer, poly(o-ethoxyaniline) (POEA), alternated with a thermosetting resin, novolac-type phenolformaldehyde (PF), crosslinked by a simple thermal treatment. The PF resin served as both alternating and crosslinking agents. The films were characterized by Fourier transform infrared (FTIR) and ultraviolet-visible (UV-Vis) spectroscopy, thermogravimetry (TG), desorption, doping/dedoping cycling and electrical measurements. The results showed that film architecture and crosslinking degree can be controlled by the conditions used for film deposition (number of bilayers, polymer concentration, pH, and deposition time), and crosslinking time. Moreover, this approach offers several advantages such as fast curing time and low cost, indicating that these films can be used to produce sensors with improved stability.

The formation of conscience : pedagogy of the sacred

This qualitative study explores Thomas Green's (1999) treatise, Voices: The Educational Formation of Conscience; for the purpose of reconstruing the transformative usefulness of conscience in moral education. Conscience is "reflexive judgment about things that matter" (Green, 1999, p. 21). Paul Lehmann (1963) suggested that we must "do the conscience over or do the conscience in" (p. 327). Thomas Green "does the conscience over", arguing that a philosophy of moral education, and not a moral philosophy, provides the only framework from which governance of moral behaviour can be understood. Narratives from four one-to-one interviews and a focus group are analysed and interpreted in search of: (a) awareness and understanding of conscience, (b) voices of conscience, (c) normation, (d) reflexive emotions, and (e) the idea of the sacred. Participants in this study (ages 16-21) demonstrated an active awareness of their conscience and a willingness to engage in a reflective process of their moral behaviour. They understood their conscience to be a process of self-judgment about what is right and wrong, and that its authority comes from within themselves. Narrative accounts from childhood indicated that conscience is there "from the beginning" with evidence of selfcorrecting behaviour. A maturing conscience is accompanied by an increased cognitive capacity, more complicated life experiences, and individualization. Moral motivation was grounded in " a desire to connect with things that are most important." A model for conscience formation is proposed, which visualizes a critical path of reflexive emotions. It is argued that schools, striving to shape good citizens, can promote conscience formation through a "curriculum of moral skills"; a curriculum that embraces complexity, diversity, social criticism, and selfhood.

Academic and professional writing in English : a study in the pedagogy of second language writing for Spanish university students.

Abarcar la enseñanza de la redacción en inglés como segunda lengua para fines académicos y profesionales en la universidad española. En primer lugar, se establece un marco teórico para la pedagogía de la redacción a base del entendimiento del texto escrito como nexo en una red compleja de relaciones sociales y negociaciones culturales. Luego se lleva a cabo un estudio de la práctica de la redacción en el contexto de la universidad española, con un análisis a fondo de los escritores y sus actitudes y expectativas, por un lado, y sus textos (un ensayo y un informe), por otro. Se analizan los textos usando técnicas cualitativas y cuantitativas. A partir de este estudio inicial, se diseña un proyecto de investigación-acción, en el que dos grupos paralelos de alumnos siguen dos programas diferentes en que se plasman dos aproximaciones distintas a la pedagogía de la redacción: el análisis textual, siguiendo la tradición del inglés para fines específicos y la escuela del género, y el análisis contextual, influenciado por los planteamientos y los procedimientos de la nueva retórica. Los textos resultantes son analizados mediante unas escalas detalladas de evaluación desarrolladas a base de los resultados del primer estudio. Los resultados de los dos programas son positivos, aunque el grupo de análisis contextual demuestra una mejora superior. Para concluir, se esboza una serie de principios que deberán servir de guía para el diseño de los futuros programas de redacción para universitarios españoles.

An unusual axial–axial combination of alternating cyclic rings in the chair conformations of hexameric water and chlorine-water clusters

An alternating hexameric water (H2O)(6) cluster and a chlorine-water cluster [Cl-2(H2O)(4)](2-) in the chair forms combine axially to each other to form a 1D chain [{Cl-2(H2O)(6)}(2-)](n) in complex [FeL2]Cl center dot(H2O)(3) (L=2-[(2-methylaminoethylimino)-methyl]-phenol)]. The water molecules display extensive H-bonding interactions with monomeric iron-organic units to form a hydrogen-bonded 2D supramolecular assembly.

Automatic and objective assessment of alternating tapping performance in Parkinson’s disease

This paper presents the development and evaluation of a method for enabling quantitative and automatic scoring of alternating tapping performance of patients with Parkinson’s disease (PD). Ten healthy elderly subjects and 95 patients in different clinical stages of PD have utilized a touch-pad handheld computer to perform alternate tapping tests in their home environments. First, a neurologist used a web-based system to visually assess impairments in four tapping dimensions (‘speed’, ‘accuracy’, ‘fatigue’ and ‘arrhythmia’) and a global tapping severity (GTS). Second, tapping signals were processed with time series analysis and statistical methods to derive 24 quantitative parameters. Third, principal component analysis was used to reduce the dimensions of these parameters and to obtain scores for the four dimensions. Finally, a logistic regression classifier was trained using a 10-fold stratified cross-validation to map the reduced parameters to the corresponding visually assessed GTS scores. Results showed that the computed scores correlated well to visually assessed scores and were significantly different across Unified Parkinson’s Disease Rating Scale scores of upper limb motor performance. In addition, they had good internal consistency, had good ability to discriminate between healthy elderly and patients in different disease stages, had good sensitivity to treatment interventions and could reflect the natural disease progression over time. In conclusion, the automatic method can be useful to objectively assess the tapping performance of PD patients and can be included in telemedicine tools for remote monitoring of tapping.
