La desaparición de los 43 normalistas en México: una aproximación al análisis crítico del discurso en la prensa
Authors: Robledo-Silvestre Carolina , Velásquez-Upegui Eva Patricia 
Published: July 2017

Se propone un análisis crítico del discurso de la prensa en el cubrimiento de la desaparición de cuarenta y tres jóvenes estudiantes en Guerrero (México) en septiembre de 2014. Para ello se explora un corpus de 2.107 documentos periodísticos, obtenido en tres meses de seguimiento a los diarios Reforma y La Jornada, con el objetivo de identificar las estrategias discursivas utilizadas en la prensa para reportar este suceso, a partir del análisis de la frecuencia léxica y la ocurrencia de frases nominales. En concreto se identifican cuatro estrategias discursivas: la negación y la neutralización, empleadas para ocultar la responsabilidad del Estado en los actos violentos; y la historización y la acreditación, como parte del discurso disidente. Todas estas estrategias están orientadas a la disputa de los campos léxicos que dan sentido a la desaparición forzada y a la violación de los derechos humanos. © Revista Colombiana de Ciencias Sociales.
“Mujeres peligrosas”: Prácticas discursivas del Estado chileno en relación con la prostitución, el comercio sexual y el trabajo sexual
Authors: Espinoza-Ibacache Jacqueline , Íñiguez-Rueda Lupicinio 
Published: July 2017

El artículo indaga las prácticas discursivas del Estado chileno en relación con las mujeres que ejercen la prostitución, comercio sexual o trabajo sexual. Hicimos un análisis basado en los estudios del discurso desde una perspectiva pragmática y realizativa del lenguaje, a partir de 18 normativas y leyes identificamos actos del habla, implicaturas e interdiscursos. En los resultados planteamos tres categorías conforme que denominamos: definiciones, prescripciones y transformaciones. Las definiciones son usadas para la descripción de la actividad y los sujetos de intervención. Las prescripciones materializan el discurso mediante obligaciones e instrucciones dictadas para el control social. Y las transformaciones, relacionadas con los dos primeros, crean una nueva situación respecto a la actividad, mediante la actualización de mecanismos y la definición de nuevos sujetos. Concluimos que las normativas producen prácticas discursivas para el control social de los cuerpos de las prostitutas, de las mujeres que ejercen comercio sexual y las trabajadoras sexuales, situándolas en la línea de la anormalidad, de esta forma definen una guía de comportamiento para el resto de las mujeres. © Revista Colombiana de Ciencias Sociales.
Imputing missing groundwater observations
Authors: Dax Achiya , Zilberbrand Michael 
Published: July 2017

AbstractIn this paper, we consider the problem of completing missing records of annual water levels. The water levels records are taken once a year, in a group of neighboring wells. The collected records are assembled into a data matrix, where each column refers to a different well and each row refers to a different year. Yet some entries of the matrix are unknown and we want to assign appropriate values to these entries. The need for solving such problems arises in many applications, as many models and programs require a complete set of data. Traditional approaches for handling missing groundwater records are based on statistical techniques for treating missing data. The current paper introduces a new approach for solving this problem. One that is able to take advantage of the ‘matrix structure’ of annual water levels. This type of ‘matrix imputing methods’ has been proved successful in many modern areas, but it has not yet been tested in hydrology. Special attention is given to the question of assessing the quality of the imputed water levels. The proposed methods are examined on a number of test cases.
Support for the Forensic DNA Database and Public Safety Concerns: An Exploratory Study
Authors: Pivetti Monica , Caggiano Antonella , Cieri Filippo , Battista Silvia Di , Berti Chiara 
Published: July 2017

Background:Over the past few decades, 32 European countries have introduced a national DNA database containing samples and/or profiles from suspected/convicted criminal offenders and biological materials from crime scenes. However, only a few studies have empirically investigated opinions on such a practice and the psychosocial factors possibly predicting public support or opposition.Objective:This study aims to preliminarily explore public support for a national DNA database in Italy. In particular, the role played by psychosocial factors, such as concern over individual rights vs. public safety, as well as genetic and juridical/legal literacy in the public’s acceptance of a forensic DNA database, was investigated.Method:Within a correlational study, a written questionnaire was administered to a sample (N = 242) of university students.Results:Participants generally showed support for a forensic DNA database. Concerns over public safety predicted the acceptance of a DNA database, with those valuing public safety being more supportive of its implementation, whereas no role was played by familiarity with the fundamental mechanisms of genetics and with the Italian Criminal Code and Criminal Procedure Code.Conclusion:Empirical research on this issue could provide policymakers and the police force with a better picture of the psychosocial factors underlying public support for the DNA database.

Taxation and Corporate Risk-Taking
Authors: Langenmayr Dominika , Lester Rebecca 
Published: July 2017

ABSTRACT
We study whether the corporate tax system provides incentives for risky firm investment. We analytically and empirically show two main findings: first, risk-taking is positively related to the length of tax loss periods because the loss rules shift some risk to the government; and second, the tax rate has a positive effect on risk-taking for firms that expect to use losses, and a weak negative effect for those that cannot. Thus, the sign of the tax effect on risky investment hinges on firm-specific expectations of future loss recovery.

Toomer's Energy Drinks: Fueling Earnings Management?
Authors: Long James H. , Mertins Lasse , Searcy DeWayne L. , Vansant Brian 
Published: July 2017

ABSTRACT
Companies around the world commonly engage in earnings management. Some earnings management techniques comply with U.S. GAAP and do not violate financial reporting standards (e.g., real earnings management techniques such as postponing research and development expenditures), other techniques clearly cross the line (e.g., misclassifying repair and maintenance expenses as capital expenditures), and some fall into a gray area (e.g., adjusting the allowance for bad debt). This case exposes students to an ethical dilemma that involves earnings management: toward the end of its fiscal year, the executive management team at Toomer's Energy Drinks' European division realize that they will fall just short of a short-term financial performance target, and consider ways in which they can manage earnings to generate sufficient performance to meet the target. The case exposes students to ways in which companies manage earnings, and encourages students to think critically about the extent to which these techniques are ethical by requiring them to apply the IMA's Statement of Ethical Professional Practice and the AICPA's Code of Professional Conduct to a realistic scenario.

Published: July 2017

ABSTRACT

Objective:
To evaluate differences in discomfort levels between patients treated with aligners and traditional fixed orthodontic appliances.

Materials and Methods:
This blinded, prospective, randomized equivalence two-arm parallel trial allocated 41 adult Class I nonextraction patients to either traditional fixed appliance (6 males and 12 females) or aligner (11 males and 12 females) treatment. Patients completed daily discomfort diaries following their initial treatment appointment, after 1 month and after 2 months. They recorded their levels of discomfort at rest, while chewing, and while biting, as well as their analgesic consumption and sleep disturbances.

Results:
Both treatment modalities demonstrated similar levels of initial discomfort. There were no significant sex differences. Patients in the traditional fixed appliances group reported significantly (P &lt; .05) greater discomfort than patients in the aligner group during the first week of active treatment. There was significantly more discomfort while chewing than when at rest. Traditional patients also reported significantly more discomfort than aligner patients after the first and second monthly adjustment appointments. Discomfort after the subsequent adjustments was consistently lower than after the initial bonding or aligner delivery appointments. A higher percentage of patients in the fixed-appliance group reported taking analgesics during the first week for dental pain, but only the difference on day 2 was statistically significant.

Conclusions:
Patients treated with traditional fixed appliances reported greater discomfort and consumed more analgesics than patients treated with aligners. This trial was not registered.
Experiences of ENDESA Group in Generation of Electricity with biomass.
Authors: Rafael Guinea  , Xavier Noguer  
Published: July 2017

ENDESA’s activities in renewable energy are carried out by Endesa Cogeneración y Renovables, SAU (ECYR), a 100% participated company. Besides its experience with industrial cogeneration, wind farms, waste-to-energy plants and minihydraulic plants, ECYR has a large experience with electricity generation with different types of biomass. This paper reviews ECYR participated plants and future projects, using residual biomass from agriculture and forestry (“orujillo”, “alperujo” and residual wood), energy crops and biogas, from landfill and from sewage plants. A brief description of the plants is given, as well as a more detailed description of the newest and most outstanding plants (“orujillo” plants of ENEMASA and La Loma, as well as landfill biogas plant in Garraf).
Co-firing of Low Rank Coal and Biomass: A Chance for Biomass Penetration in the Renewables.
Authors: Antonio Valero  
Published: July 2017

This paper presents a co-firing experience, with coal and biomass, whose objective was to prove the technical, environmental and economical feasibility (although the paper does not deal with this last one) of the implantation of this technology in a power plant of pulverised low rank coal. Precisely, this kind of coal particularities, specially its low energy density (kJ/m3), with similar values to most of the different dry biomass resources, is what makes a difference between this project and other co-firing experiences carried out previously.With regard to the main results, it must be pointed out that when introducing in the boiler a 5% of biomass: • No operation problem arose and no noticeable reduction in the boiler efficiency was caused. • Apart from the expected reductions in CO2 and SO2, an important decrease in NOx emissions was detected. • No emissions increase of CO, particles and volatile compounds were detected. Another aspect dealt in the project was the study of the possible impacts of forest biomass harvesting on the sustainability of the forest. Considering the low additional investments needed for establishing a Co-firing Biomass Power Plant, this technology is a real chance for introducing biomass in Spain. It only needs the same government incentives as other renewable technologies already receive.

Published: July 2017

This paper describes a method for the evaluation of the economical losses caused by voltage sags in an industrial facility in which the presence of adjustable speed drives (ASD's) is significant. The nature of the data that must be provided in order to have practical information about system reliability at the point of common coupling (PCC) is analysed in detail. Then, the adequate methodology for considering the technical and economical consequences of voltage sags on the production is described for the case of critical drives.
The analysis that is carried out in this work is also useful for making critical evaluations on the interest that the different solutions (ride-through alternatives)oriented to the improvement of performance of these apparatus can have in a particular case.

Authors: Edelweiss Roberta Krahe , Garzon Mauricio Ricardo Cabas 
Published: July 2017

Compreendendo tanto a vitalidade da cidade a partir de seus processos de transformação, quanto a construção de uma identidade a partir de ações da sociedade civil constituintes de valores de memória, a abordagem deste artigo centra-se nos recentes eventos efêmeros de apropriação do espaço público realizados na capital do estado brasileiro do Rio Grande do Sul, Porto Alegre. Além de abordar a apropriação da cidade contemporânea — entendida como ‘ato de habitar’ e ‘construtora de lugar’ —, propõe uma reflexão sobre o significado desses eventos nos espaços públicos da capital gaúcha.

Percepciones de autoevaluación: Autoestima, autoeficacia y satisfacción vital en la adolescencia
Authors: Reina Mª Del Carmen 
Published: July 2017

Resumen: En este estudio se analizan las relaciones entre tres variables relativas a la autoevaluación como son la autoestima, la autoeficacia y la satisfacción vital, así como sus tendencias evolutivas y las diferencias de género en una muestra de 2400 adolescentes con edades comprendidas entre los 12 y 17 años pertenecientes a 20 centros educativos de Andalucía Occidental. Por otro lado, se presentan las relaciones de estas tres variables con el estilo educativo parental. Los resultados indicaron correlaciones significativas entre las variables de autoevaluación, así como con las dimensiones del estilo parental. Concretamente, los niveles de afecto-comunicación y el sentido del humor de madres y padres fueron aspectos que se relacionaron de forma muy significativa con la autoevaluación adolescente. Por otra parte, aparecieron importantes diferencias de género en las trayectorias que la autoestima, la autoeficacia y la satisfacción vital siguen durante la adolescencia, ya que mientras que en los chicos se observaron pocos cambios, en las chicas la tendencia fue descendente, de forma que las adolescentes de más edad mostraron las autovaloraciones más bajas. Adolescents own perceptions of self-evaluation: Self esteem, self efficacy and life satisfaction Abstract: In this study we analyse the relationships between three variables of self-evaluations, being self esteem, self efficacy and life satisfaction. Moreover, we study the evolution of these three aspects during adolescence paying attention to gender differences. The sample was made up of 2400 teenagers aged between 12 and 17 years old taken from 20 high schools in Western Andalusia. In this study we also analyse the relationship between teenager self evaluation and parenting style. Our results show, on one hand, high correlation between self esteem, self efficacy and life satisfaction, and on the other hand, between teenager self evaluation and parenting style. In fact, parental warmth and communication and sense of humor show high correlation with adolescent self evaluation. We also found increasing differences between boys and girls as regards their self esteem, self efficacy and life satisfaction as adolescence progressed. Specifically, little changed was observed in boys, whereas girls’ self-evaluation decreased with age.
El análisis de las fortalezas psicológicas en la adolescencia: Más allá de los modelos de vulnerabilidad
Authors: Giménez Montse , Vázquez Carmelo , Hervás Gonzalo 
Published: July 2017

Resumen: Frente a la imagen traumática y conflictiva que se asocia tradicionalmente a la adolescencia, desde el marco de la Psicología Positiva se ofrece una nueva conceptualización que sugiere una visión más optimista y positiva de este periodo de la vida. El estudio de las fortalezas humanas, término descrito por Peterson y Seligman (2004), ofrece un contexto potencialmente útil para conocer los aspectos y cualidades positivas de los más jóvenes y apuesta por un modelo de intervención centrado en las potencialidades frente al déficit. El presente artículo realiza una revisión sobre los resultados encontrados en la literatura que, de modo directo o indirecto, apoyan la existencia y relevancia de cada una de las fortalezas señaladas en el marco descriptivo de estos autores. Finalmente, discutimos las repercusiones que el estudio de las potencialidades puede tener en el desarrollo de programas educativos, de prevención y de intervención. The analysis of the psychological strengths in adolescence: Beyond vulnerability models Abstract: Against a traumatic and troubled image that is traditionally associated with adolescence, Positive Psychology opens a novel conceptual framework offering a more optimistic and positive view of this period of life. The study of ‘human strengths’, a term suggested by Peterson and Seligman (2004), offers a potentially useful tool to understand the positive aspects and features of the youth. That approach can also provide a model of intervention focusing on individual’s potentials rather than on deficits. This paper reviews the results found in the literature that directly or indirectly supports the existence and relevance of each of the strengths identified in the descriptive framework of these authors. Finally, we discuss the implications that the study of human strengths may have in the development of educational, preventive and intervention programs.
Fortalecimiento de competencias matemáticas tempranas en preescolares, un estudio chileno

Published: July 2017

Resumen: El artículo describe el efecto positivo de un programa de intervención basado en la comprensión del número en los niveles de competencia matemática temprana que presentan preescolares chilenos, en las áreas de competencias relacionales y numéricas evaluadas con el Test de Evaluación Matemática Temprana Utrech (TEMT-U), versión española del Utrecht Early Numeracy Test. El estudio permite constatar que existen diferencias significativas en el nivel de competencias matemáticas tempranas entre aquellos grupos sometidos a este tipo de programa por sobre aquellos que, en igual período de tiempo, sólo recibieron el influjo de los contenidos y actividades de la secuencia curricular tradicional para la población escolar chilena. Se observan efectos positivos del programa independientemente del nivel educativo al cual asisten los niños y niñas, y las competencias relacionales o piagetianas muestran niveles de logro superiores. Los resultados muestran que no se observan diferencias en los niveles de competencia matemática entre niños y niñas, contrariamente a lo que se observa en años posteriores. Strengthening early math skills in preschoolers, a Chilean study. Abstract: The article describes the positive effect in an intervention program based on number comprehension in early math skill levels that Chilean preschoolers present in the relational and numerical skill areas evaluated with the Test of Early Mathematics Assessment Utrecht (TEMT-U), the Spanish version of the Utrecht Early Numeracy Test. The study reveals that there are significant differences in the early math skills levels among those groups subjected to this type of program and those that in the same period of time were only influenced by the content and activities of the traditional curriculum sequence in the Chilean school population. There are positive effects in the program regardless of the educational level that children attend. There are also relational or skills Piagetian that show higher achievement levels. The results prove that there are no differences in mathematical literacy levels between boys and girls, contrary to what is observed in later years.
