Analyzing The Effects of Post-Traumatic Stress Disorder on Marital Satisfaction Among The Veteran Latino Population of South Texas

The current study examined the relation between combat exposure and Post-Traumatic Stress Disorder (PTSD), PTSD and marital satisfaction and the influence of religion/spirituality as a moderator. Study consisted of 31 participants; male veterans (n=19) and female spouses (n=12), of which 11 were couples (n=22). Participants were recruited from the University of Texas Pan-American (UTPA), local veteran organization and networking. The sample completed self-report measures for combat exposure, PTSD, marital satisfaction, and religiosity/spirituality. When using a correlation analyses to examine the relation between combat exposure and PTSD and PTSD and marital satisfaction, results showed a negative relation for both; thus, supporting the first hypothesis. Moreover, when using a regression analyses to examine religiosity/spirituality as a moderator, results did not support the second hypothesis

Methodology for developing an advanced communications system for the Deaf in a new domain

A methodology for developing an advanced communications system for the Deaf in a new domain is presented in this paper. This methodology is a user-centred design approach consisting of four main steps: requirement analysis, parallel corpus generation, technology adaptation to the new domain, and finally, system evaluation. During the requirement analysis, both the user and technical requirements are evaluated and defined. For generating the parallel corpus, it is necessary to collect Spanish sentences in the new domain and translate them into LSE (Lengua de Signos Española: Spanish Sign Language). LSE is represented by glosses and using video recordings. This corpus is used for training the two main modules of the advanced communications system to the new domain: the spoken Spanish into the LSE translation module and the Spanish generation from the LSE module. The main aspects to be generated are the vocabularies for both languages (Spanish words and signs), and the knowledge for translating in both directions. Finally, the field evaluation is carried out with deaf people using the advanced communications system to interact with hearing people in several scenarios. In this evaluation, the paper proposes several objective and subjective measurements for evaluating the performance. In this paper, the new considered domain is about dialogues in a hotel reception. Using this methodology, the system was developed in several months, obtaining very good performance: good translation rates (10% Sign Error Rate) with small processing times, allowing face-to-face dialogues

Total Degree Formula for the Generic Offset to a Parametric Surface

We provide a resultant-based formula for the total degree w.r.t. the spatial variables of the generic offset to a parametric surface. The parametrization of the surface is not assumed to be proper.Comment: Preprint of an article to be published at the International Journal of Algebra and Computation, World Scientific Publishing, DOI:10.1142/S021819671100680

Design, development and field evaluation of a Spanish into sign language translation system

This paper describes the design, development and field evaluation of a machine translation system from Spanish to Spanish Sign Language (LSE: Lengua de Signos Española). The developed system focuses on helping Deaf people when they want to renew their Driver’s License. The system is made up of a speech recognizer (for decoding the spoken utterance into a word sequence), a natural language translator (for converting a word sequence into a sequence of signs belonging to the sign language), and a 3D avatar animation module (for playing back the signs). For the natural language translator, three technological approaches have been implemented and evaluated: an example-based strategy, a rule-based translation method and a statistical translator. For the final version, the implemented language translator combines all the alternatives into a hierarchical structure. This paper includes a detailed description of the field evaluation. This evaluation was carried out in the Local Traffic Office in Toledo involving real government employees and Deaf people. The evaluation includes objective measurements from the system and subjective information from questionnaires. The paper details the main problems found and a discussion on how to solve them (some of them specific for LSE)

Model for interoperability evaluation in e-government services

proceedings of IV International Conference on Multimedia and Information & Communication Technologies in Education, m-ICTE2006, Sevilla, Spain, November 22-25, 2006The recent publication of the European and Spanish interoperability frameworks implies that public organizations should start a change management process in order to adapt their technologies and procedures to the new standard as a way to guarantee information interoperability across e-government services.The main justification for this research is to disseminate the interoperability standards among Spanish public organizations and to provide methodological and technical guidelines to facilitate the adaptation process, and to foster the usage of new techniques and procedures for information integration and management. The aim of the research consists of identifying the essential aspects to take into consideration to guarantee the information and knowledge interoperability in e-government services. In this context good practices in information interoperability are taken into account and three basic approaches are identified: (1)Information and knowledge management: mark-up languages, open software and formats, and electronic document processing; (2) Metadata for knowledge representation in electronic resources; and (3) Web accessibility to improve access for all.Publicad

The detection of single electrons by means of a Micromegas-covered MediPix2 pixel CMOS readout circuit

A small drift chamber was read out by means of a MediPix2 readout chip as direct anode. A Micromegas foil was placed 50 $\mu$m above the chip, and electron multiplication occurred in the gap. With a He/Isobutane 80/20 mixture, gas multiplication factors up to tens of thousands were achieved, resulting in an efficiency for detecting single electrons of better than 90% . We recorded many frames containing 2D images with tracks from cosmic muons. Along these tracks, electron clusters were observed, as well as delta-rays.Comment: 15 pages, 9 included postscript figures, 5 separate jpeg figures, submitted to Nucl. Instr. and Meth. A.

Real-time phase-shift detection of the surface plasmon resonance

We investigate a method to directly measure the phase of a laser beam reflected from a metallic film after excitation of surface plasmon polaritons. This method permits real time access to the phase information, it increases the possible speed of data acquisition, and it may thus prove useful for increasing the sensitivity of surface plasmon based sensors
