Third-party complaints and firm performance: an application in Spanish banking

This article focuses on the impact of third-party complaints on firm performance. We propose two research hypotheses, which are developed from the literature of dissatisfaction, emotions, and economics. The methodology is based on an event study to estimate variation in firm share returns in the stock market due to the publication of the Annual Complaints Service Report by the Bank of Spain; as well as a regression analysis to examine the impact of the number of complaints per branch on the variation obtained. The empirical focus is on a sample of eleven banks to which complaints were made and which were quoted on the Spanish Stock Exchange between 1992 and 2001. The results show a negative impact of the publication of these annual complaint reports on the share returns of the banks concerned. Additionally, these returns have a negative relationship with the number of complaints per branch.

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.

Factors Associated With Women’s Reporting of Intimate Partner Violence in Spain

In Spain, in 2013, the 20% of women who were murdered by their partner had reported him previously. We analyze the 2011 Spanish-Macrosurvey on Gender Violence to identify and analyze the prevalence of and the principal factors associated with reporting a situation of intimate partner violence (IPV) and the main reasons women cite for not filing such reports, or for subsequently deciding to withdraw their complaint. Overall, 72.8% of women exposed to IPV did not report their aggressor. The most frequent reasons for not reporting were not giving importance to the situation (33.9%), and fear and lack of trust in the reporting process (21.3%). The main reasons for withdrawing the complaint were cessation of the violence (20.0%), and fear and threats (18.2%). The probability of reporting increased among women with young children who were abused, prevalence ratio (95% confidence interval [CI]): 2.14 [1.54, 2.98], and those whose mother was abused, prevalence ratio (95% CI): 2.25 [1.42, 3.57]. Always focusing on the need to protect women who report abuse, it is necessary to promote the availability of and access to legal resources especially among women who use them less: women who do not have children and women who do not have previous family exposure to violence.

Perfil sociodemográfico del feminicidio en España y su relación con las denuncias por violencia de pareja

Objetivo: Analizar las características asociadas al riesgo de feminicidio en España entre mujeres expuestas a la violencia de pareja o análogo y su posible asociación con las denuncias a los agresores. Métodos: Se realizó un estudio de casos y controles para el periodo 2010-2011. Los casos, 135 mujeres mayores de edad, asesinadas por su pareja o análogo durante dicho periodo, se identificaron a través de la página web de la Federación de Asociaciones de Mujeres Separadas y Divorciadas, y de los informes del Consejo General del Poder Judicial. Los controles, 185 mujeres expuestas a la violencia de pareja el último año, proceden de la Macroencuesta de Violencia de Género 2011. La asociación entre la denuncia y el riesgo de feminicidio se estimó mediante modelos de regresión logística multivariada. Resultados: No se encontró asociación entre denunciar al agresor y el riesgo de ser asesinada (odds ratio [OR]: 1,38; intervalo de confianza del 95% [IC95%]: 0,68-2,79). Las mujeres inmigrantes expuestas a la violencia de pareja registraron una mayor probabilidad de ser asesinadas (ref.: mujeres españolas; OR: 5,38; IC95%: 2,41-11,99). Esta asociación también se observó en las mujeres que vivían en zonas rurales (ref: zonas urbanas; OR: 2,94; IC95%: 1,36-6,38). Conclusiones: La denuncia judicial al agresor no parece modificar el riesgo de asesinato entre las mujeres expuestas a la violencia de pareja. Las medidas de protección a las mujeres deberían extremarse en las mujeres inmigrantes y las que viven en el medio rural.
