The social economy as a political priority. Analysis of participator y budgets in Ecuador

2020

En Ecuador, con la aprobación de la constitución en 2008, se ha impulsado la consecución del fin del buen vivir (Sumak Kawsay), fijando como objetivo establecer un sistema económico acorde a sus principios, incorporando entre sus prioridades el fomento de la economía social. El objetivo del trabajo es conocer si las preferencias de la ciudadanía están alineadas con las del gobierno. Para ello se recurre al análisis de los presupuestos participativos en Ecuador, como herramienta que permite conocer las preferencias de la ciudadanía. Concretamente se realizan tres estudios de caso representativos de las distintas regiones naturales de Ecuador: Quito, Guayaquil y Sucumbíos. Como principales re…

Diseño y validación de un cuestionario para conocer la opinión del alumnado de secundaria sobre la Música Festera y sus aplicaciones en el aula

2016

El objetivo del presente estudio es presentar el diseno y la validacion de un cuestionario para conocer la opinion del alumnado de ensenanza secundaria de Torrellano (Alicante) sobre la Musica Festera y sus posibilidades de aplicacion en el aula de secundaria. La poblacion de referencia esta formada por 597 alumnos de musica distribuidos en cuatro cursos de ensenanza secundaria (1o, 2o, 3o y 4o). Si trabajamos con un nivel de confianza del 95% y un margen de error del 5%, el tamano que precisa la muestra de los alumnos para ser representativa de la poblacion de referencia es de 234. El cuestionario fue enviado a toda la poblacion y la muestra generadora de datos resulto ser de 484. La prime…

Cuantificación de la fibrosis hepática mediante biomarcadores de imagen

2018

There is a need for early identification of patients with chronic liver diseases due to their increasing prevalence and morbidity-mortality. The degree of liver fibrosis determines the prognosis and therapeutic options in this population. Liver biopsy represents the reference standard for fibrosis staging. However, given its limitations and complications, different non-invasive methods have been developed recently for the in vivo quantification of fibrosis. Due to their precision and reliability, biomarkers' measurements derived from Ultrasound and Magnetic Resonance stand out. This article reviews the different acquisition techniques and image processing methods currently used in the evalu…

Validation of the German Version of the Music-Empathizing-Music-Systemizing (MEMS) Inventory (Short Version)

2018

Background: Kreutz et al. (2008) developed the Music-Empathizing-Music-Systemizing (ME-MS) Inventory to extend Baron-Cohen's cognitive style theory to the domain of music. We sought to confirm the ME-MS construct in a German sample and to explore these individual differences in relation to music preferences. Methods: The German adaptation of the MEMS Inventory was achieved by forward and backward translation. A total of 1014 participants (532 male, age: 33.79 ± 11.89 years) completed the 18-item short version of the MEMS Inventory online. Confirmatory factor analysis (CFA) was performed and cut-off values were established to identify individuals who could be classified as ME, Balanced, or M…

Intra-individual variability in TSH levels of healthy women during the first half of pregnancy

2017

TSH is the parameter most widely accepted to assess thyroid function, especially in pregnant women. The aim of this current study was to analyze intra-individual changes in TSH during the first half of pregnancy in women with TSH levels higher than 2.5mIU/L in early pregnancy.An observational, prospective study was conducted on 243 healthy pregnant women in the first trimester of pregnancy. Thyroid function was assessed by testing TSH and free T4 levels. A subgroup of women with TSH levels2.5mIU/L underwent additional tests (TSH, free T4, peroxidase antibodies). Information on dietary iodine intake and/or iodine supplements was also recorded.Mean TSH level was 1.89mIU/L (range 0.024-6.48mIU…

Method optimization to measure polybrominated diphenyl ether (PBDE) concentrations in soils of Bratislava, Slovakia.

2010

We modified an analytical method to determine polybrominated diphenyl ethers (PBDEs) in urban soils of Bratislava (Slovakia). Gel permeation chromatography (GPC) introduced as a clean-up step for soil extracts substantially reduced matrix enhancements when PBDEs were measured with gas chromatography-negative chemical ionization-mass spectrometry (GC-NCI-MS). The resulting method proved to be accurate, precise, and showed low detection limits. The sum of 15 PBDE concentrations in surface horizons of Bratislava soils ranged from 87 to 627 pg g(-1). PBDE concentrations were mostly higher in surface than deeper horizons probably because of atmospheric deposition and lack of substantial vertical…

Traceability of static reactive energy meters in the presence of harmonics: theoretical considerations and a DAQ-based reference meter

2013

This paper deals with some problems related to the measurements traceability with static meters for reactive energy. These problems arise when the meters operate in the presence of harmonics, which can negatively affect their performances, depending on implemented metric. The paper analyzes the problem in the light of both in-force and draft standards, from the viewpoint of the performances of both commercial meters and reference standard instruments. The analysis is supported by some experimental tests, which are carried out by means of a reference meter, based on data acquisition boards, which can be used in both sinusoidal and distorted conditions.

In Defense of Cities : On Negative Presentation of Urban Areas in Environmental Preference Studies

2019

This paper critiques a common research method, image-based studies, in assessing environmental preferences. The method is used, in particular, in the fields of environmental psychology, landscape studies, and health studies, here called empirical environmental preference studies or EEP studies. I argue that the established view in the EEP field that nature is inherently experienced as more aesthetically appealing and restorative than urban environments may be biased because of the image-based method. This paper presents a literature review of EEP studies, discussing them in a framework of environmental and everyday aesthetics. The conclusion is that EEP studies may strip cities of their phy…
