Sentiment classification for early detection of health alerts in the chemical textile domain

In the chemical textile domain experts have to analyse chemical components and substances that might be harmful for their usage in clothing and textiles. Part of this analysis is performed searching opinions and reports people have expressed concerning these products in the Social Web. However, this type of information on the Internet is not as frequent for this domain as for others, so its detection and classification is difficult and time-consuming. Consequently, problems associated to the use of chemical substances in textiles may not be detected early enough, and could lead to health problems, such as allergies or burns. In this paper, we propose a framework able to detect, retrieve, and classify subjective sentences related to the chemical textile domain, that could be integrated into a wider health surveillance system. We also describe the creation of several datasets with opinions from this domain, the experiments performed using machine learning techniques and different lexical resources such as WordNet, and the evaluation focusing on the sentiment classification, and complaint detection (i.e., negativity). Despite the challenges involved in this domain, our approach obtains promising results with an F-score of 65% for polarity classification and 82% for complaint detection.

Constructing an Indigenous Model of the Self to Address Cultural and Mental Health Issues in the Canadian Subarctic

Since the last decades, academic research has paid much attention to the phenomenon of revitalizing indigenous cultures and, more precisely, the use of traditional indigenous healing methods both to deal with individuals' mental health problems and with broader cultural issues. The re-evaluation of traditional indigenous healing practices as a mode of psychotherapeutic treatment has been perhaps one of the most interesting sociocultural processes in the postmodern era. In this regard, incorporating indigenous forms of healing in a contemporary framework of indigenous mental health treatment should be interpreted not simply as an alternative therapeutic response to the clinical context of Western psychiatry, but also constitutes a political response on the part of ethno-cultural groups that have been stereotyped as socially inferior and culturally backward. As a result, a postmodern form of "traditional healing" developed with various forms of knowledge, rites and the social uses of medicinal plants, has been set in motion on many Canadian indigenous reserves over the last two decades.

Metaestudio cualitativo sobre vivencias y gestión del cotidiano en adultos mayores que padecen enfermedades crónicas

Objetivo: Describir la experiencia cultural, interpersonal y personal de los adultos mayores con enfermedades crónicas e identificar las estrategias y redes de apoyo que utilizan en su entorno cotidiano para gestionar la enfermedad. Método: Se desarrolló un metaestudio tipo metaanálisis cualitativo. La estrategia metodológica constó de cuatro etapas: Búsqueda bibliográfica, Categorización de los estudios, Evaluación de la calidad metodológica y Análisis de resultados. Resultados: Se obtuvo una muestra bibliográfica de 22 estudios de naturaleza cualitativa. Los hallazgos se organizaron en 4 categorías: Compresión del padecimiento, Autogestión en el cotidiano, Percepción de los Servicios de Salud y Cotidiano del cuidador. Conclusiones: El esfuerzo de los adultos mayores por alcanzar un nuevo equilibrio social y personal se articula en las estrategias de autogestión que utilizan en su día a día para afrontar sus padecimientos. Las interrelaciones con los servicios de salud, familia y redes de apoyo son fundamentales para gestionar la cronicidad.
