Daylighting Performance of Solar Control Films for Hospital Buildings in a Mediterranean Climate

One of the main retrofitting strategies in warm climates is the reduction of the effects of solar radiation. Cooling loads, and in turn, cooling consumption, can be reduced through the implementation of reflective materials such as solar control films. However, these devices may also negatively affect daylight illuminance conditions and the electric consumption of artificial lighting systems. In a hospital building, it is crucial to meet daylighting requirements as well as indoor illuminance levels and visibility from the inside, as these have a significant impact on health outcomes. The aim of this paper is to evaluate the influence on natural illuminance conditions of a solar control film installed on the windows of a public hospital building in a Mediterranean climate. To this end, a hospital room, with and without solar film, was monitored for a whole year. A descriptive statistical analysis was conducted on the use of artificial lighting, illuminance levels and rolling shutter aperture levels, as well as an analysis of natural illuminance and electric consumption of the artificial lighting system. The addition of a solar control film to the external surface of the window, in combination with the user-controlled rolling shutter aperture levels, has reduced the electric consumption of the artificial lighting system by 12.2%. Likewise, the solar control film has increased the percentage of annual hours with natural illuminance levels by 100–300 lux

Indoor Air Quality Assessment: Comparison of Ventilation Scenarios for Retrofitting Classrooms in a Hot Climate

Current energy e ciency policies in buildings foster the promotion of energy retrofitting of the existing stock. In southern Spain, the most extensive public sector is that of educational buildings, which is especially subject to significant internal loads due to high occupancy. A large fraction of the energy retrofit strategies conducted to date have focused on energy aspects and indoor thermal comfort, repeatedly disregarding indoor air quality criteria. This research assesses indoor air quality in a school located in the Mediterranean area, with the objective of promoting di erent ventilation scenarios, based on occupancy patterns and carbon dioxide levels monitored on site. Results show that manual ventilation cannot guarantee minimum indoor quality levels following current standards. A constant ventilation based on CO2 levels allows 15% more thermal comfort hours a year to be reached, compared to CO2-based optimized demand-controlled ventilation. Nevertheless, the latter ensures 35% annual energy savings, compared to a constant CO2-based ventilation, and 37% more annual energy savings over that of a constant ventilation rate of outdoor air per person

Assessment of Indoor Environmental Quality for Retrofitting Classrooms with An Egg-Crate Shading Device in A Hot Climate

In the Mediterranean climate, a large number of educational buildings suffer from discomfort due mostly to energy-deficient thermal envelopes and a lack of cooling systems. Impending climate change is expected to worsen overheating in classrooms, especially during heatwave periods. Therefore, the protection of window openings to reduce incident solar radiation while maintaining adequate indoor environmental quality must be considered a necessary key focus. The main objective of this research is to assess the influence of an egg-crate shading device on the indoor environmental quality of a classroom in Southern Spain. To do so, two classrooms—with and without this shading device—were simultaneously monitored over a whole year. The implementation of an egg-crate shading device allowed for a significant reduction of the incident solar radiation, both in summer and mid-season (around 45–50%), which objectively slightly conditioned indoor operative temperatures. Given the noticeable influence of the user patterns observed, indoor illuminance was also improved, as the rolling shutters tended to be opened at higher aperture levels

Thermal and Lighting Consumption Savings in Classrooms Retrofitted with Shading Devices in a Hot Climate

Most educational buildings in southern Spain do not meet current energy requirements as weak thermal envelopes and the lack of cooling systems lead to severe discomfort in classrooms, especially when temperatures are above 30 °C. Given that global warming is expected to worsen this situation in coming decades, one of the first steps to be taken is to protect window openings from high levels of solar radiation by adding shading devices to reduce indoor temperatures and improve visual comfort. The aim of this research is to evaluate the reduction in thermal and lighting consumption in a classroom where a solar protection system in the form of an egg-crate shading device was installed. Two classrooms—one with an egg-crate device and another with no shading system—were monitored and compared for a whole year. The use of an egg-crate device in these classrooms reduced indoor operative temperatures during warmer periods while also improving indoor natural illuminance levels. Moreover, annual electric air conditioning consumption decreased by approximately 20%, with a 50% reduction in electric lighting consumption. These savings in electricity were largely conditioned by the use patterns observed in these ambient systems.Spanish government BIA2014-53949-RMinistry of Economy and Competitiveness, Spanish GovernmentEuropean Regional Development Fun

Determinantes del tipo impositivo efectivo en el sector turístico: un modelo dinámico con datos de panel

This paper presents a dynamic model of the Effective Tax Rate (ETR) in the tourism sector. A dynamic model where the lagged endogenous variable ETR has been included as a regressor to identify the dynamic structure of the variable due to the existence of temporal adjustments between the short and long run in ETR payments has been estimated. The empirical analysis based on a panel data set over the 2008-2013 period explores the determinants of the ETR variable by using a Generalised Method of Moments (GMM) estimator controlling for heterogeneity in the tourism sector. The Arellano-Bond system GMM estimator has been used to estimate the model. The study seeks to shed light on the determinants of tax burden in the tourism sector covering the lack of studies on this topic. The findings obtained suggest that the ETR borne is determined by size, financing structure and type of entity. We deem the finding of the existence of non-linear relationships between ETR and size and financing structure relevant.Este artículo presenta un modelo dinámico para el Tipo Impositivo Efectivo (TIE) en el sector turístico. Este modelo dinámico ha sido estimado usando la variable endógena retardada TIE como regresor para identificar la estructura dinámica de dicha variable, debido a la existencia de ajustes entre el corto y largo plazo en los pagos del TIE. El análisis empírico basado en datos de panel en el periodo 2008-2013 explora los determinantes de la variable TIE utilizándose el estimador del Método Generalizado de Momentos (GMM) controlando la heterogeneidad en el sector turístico. El estimador de Arellano-Bond ha sido utilizado para estimar el modelo. Este estudio busca arrojar luz sobre los determinantes de las cargas impositivas en el sector turístico debido a la escasez de estudios en esta materia. Los resultados obtenidos sugieren que el TIE se encuentra determinado por el tamaño, la estructura financiera y el tipo de empresa. Igualmente consideramos relevante el hallazgo de relaciones no lineales entre el TIE y el tamaño y la estructura de financiación

Development and Validation of an Attributional Style Questionnaire for Adolescents.

Política de acceso abierto tomada de: https://v2.sherpa.ac.uk/id/publication/3503 (Accepted Version [pathway a])We describe the development and psychometric characteristics of a new version of the Attributional Style Questionnaire (ASQ; Seligman, Abramson, Semmell, & Von Baeyer, 1979)—a version called the Attributional Style Questionnaire for Adolescents (ASQ-A)—using 3 samples (Ns 547, 438, and 240) of Spanish secondary school students. In Study 1, the initial pool of 87 items was reduced to 54. Study 2 further analyzed the 54 scale items and revealed that the Internality, Stability, and Globality subscale scores had good reliability, good factorial construct validity, and satisfactory associations with maladaptive mood ratings. In Study 3, the regression analyses showed good and specific predictive validities of ASQ-A subscales for the attributions that the adolescents made about a particular real-life stressful situation. Study 4 showed that over an 8-month period the changes in the Stability and Globality subscales depended on the intensity of stressful life events experienced in this period. Overall, the studies revealed that the new ASQ-A served as an appropriate instrument to assess attributional style in adolescents

Daily stress and coping styles in adolescent hopelessness depression: Moderating effects of gender.

The hopelessness depression (HD) theory assumes a number of contributing factors to the development of hope- lessness expectations and HD symptoms. However, little research has been conducted in order to examine gen- der differences in the relationship of these factors with HD. This study explored the relationship of daily stress and coping styles with HD in adolescents and analysed the moderating effects of gender. Secondary students (N = 480; aged 13–17) completed the Hopelessness Scale, the Hopelessness Depression Symptoms Question- naire, the Problem Questionnaire and the Coping Across Situations Questionnaire. Using hierarchical regression analyses, results showed a moderating effect of gender on the relationship between daily stress and hopelessness expectations, which revealed a significant effect for boys despite the fact that girls experienced more daily stress than boys. Regarding coping styles, results showed that the avoidant coping style predicted HD independently of gender and, interestingly, a moderating effect of gender for the active and internal coping styles. While the active coping style showed a protective effect for HD symptoms in girls, the internal coping style played an analogous role in boys, suggesting that girls would benefit from being more action-prone and boys from being more reflection-prone in order to prevent HD

The McMaster Family Assessment Device (FAD) dimensions involved in the prediction of adolescent depressive symptoms and their mediating role in regard to socioeconomic status

Family functioning plays an important role in explaining the high prevalence of depressive symptoms in adolescents and it is necessary to identify the family functioning characteristics responsible for this relationship. In turn, while socioeconomic status (SES) is associated with adolescent depressive symptoms, the mechanisms that explain this relationship are largely unknown. In this study, we used the McMaster Family Assessment Device (FAD) to obtain a picture of the family functioning dimensions that genuinely contribute to explaining the relationship between family functioning and adolescent depressive symptoms and analyzed the mediating effect of family functioning on the impact of SES on depressive symptoms. Regression-based conditional process analysis was used with a sample of 636 adolescents aged 12–17 years. Pratt's measures in regression analyses showed that 95% of the variance in depressive symptoms was accounted for by three of the six FAD dimensions: the ability to experience and express emotions appropriately—Affective Responsiveness— the ability to maintain adequate involvement among family members—Affective Involvement—and the ability to set and abide by rules and standards of behavior— Behavioral Control. Results also showed that the impact of SES on depressive symptoms was mediated by the existence of clear expectations about standards of behavior and behavioral patterns for handling family tasks—Behavioral Control and Roles—and, for the boys, by experiencing and expressing emotions appropriately. The results emphasize the importance of affect and clear-cut family rules to prevent adolescent depressive symptoms and suggest that the existence of family rules and roles buffer the impact of SES on adolescent wellbeingFunding for open access charge: University of Malaga/CBU
