Versión española abreviada del cuestionario de ansiedad relacionada con el embarazo

The aim of this study is to obtain a Spanish brief version of the Pregnancy Related Anxiety Questionnaire and analyse its psychometric properties. A longitudinal study was carried out on a sample of 569 Spanish pregnant women with normal risk status. Participants were assessed in the first, second, and third trimesters of pregnancy by using a socio-demographic and obstetric-gynaecological questionnaire, the PRAQ-55, the Edinburgh Postnatal Depression Scale, and the State-Trait Anxiety Inventory. PRAQ-55 items with factorial loads > .50 were selected resulting in a final scale of 20 items. A cut-off point ≥ 67 (85th percentile) was used to identify women with high pregnancy-specific anxiety. The findings revealed that PRAQ-20 can be considered a useful screening tool in clinical practice to assess pregnancy-related anxiety in both nulliparous and multiparous pregnant womenEl objetivo de este estudio es obtener una versión breve en español del Cuestionario de Ansiedad Relacionada con el Embarazo y analizar sus propiedades psicométricas. Se realizó un estudio longitudinal en una muestra de 569 mujeres embarazadas españolas con un embarazo de riesgo normal. Se evaluó a las participantes en el primer, segundo y tercer trimestre de embarazo utilizando un cuestionario sociodemográfico y obstétrico-ginecológico, el PRAQ-55, la Escala de Depresión Postparto de Edimburgo y el Inventario de Ansiedad de Estado-Rasgo. Se seleccionaron los ítems de la PRAQ-55 con cargas factoriales > .50, lo que dio como resultado una escala final de 20 ítems. Se utilizó como punto de corte 67 (percentil 85) para identificar a aquellas mujeres con elevada ansiedad específica del embarazo. Los resultados mostraron que el PRAQ-20 puede considerarse una herramienta de cribado útil en la práctica clínica para evaluar la ansiedad relacionada con el embarazo tanto en mujeres embarazadas nulíparas como multíparasS

Prevalence of Depression during Pregnancy in Spanish Women: Trajectory and Risk Factors in Each Trimester

The aims of this research were to determine the trajectories of probable depression and major depression during pregnancy and to identify the associated and predictor variables (sociodemographic, pregnancy-related, and psychological) for both conditions in each trimester of pregnancy. A longitudinal study was carried out with 569 pregnant Spanish women who were assessed in the first, second, and third trimesters of pregnancy. Depression was assessed using the Edinburgh Postnatal Depression Scale and a clinical interview. Measures of anxiety and stress were also included. The prevalence of probable depression in the first, second, and third trimesters was 23.4%, 17.0%, and 21.4%, respectively, and that of major depression was 5.1%, 4.0%, and 4.7%. Thus, the prevalence of both conditions was the highest in the first and third trimesters. The trajectories of probable depression and major depression followed the same pattern throughout pregnancy. All of the psychological variables studied were associated with both conditions in all three trimesters, with perceived stress being a predictor at all times. The association between the other variables and both conditions of depression was similar. Two exceptions stand out: having had previous miscarriages, which was only associated with probable depression and was also a predictor, in the first trimester; and complications during pregnancy, which was only associated with probable and major depression in the third trimester. These findings should be taken into account in routine pregnancy follow-ups, and necessary interventions should be started in the first trimester.S

El consumo de masas desde una dinámica cooperativa: “Mejor compartir que consumir”

El presente Trabajo de Fin de Grado parte del estudio de los diferentes períodos de prácticas del Grado en Educación Primaria. A lo largo de este análisis queda plasmadami evolución. Esta se ve reflejada en la propuesta de mejora, elaborada de manera fundamentada y razonada. Una vez analizado mi proceso de aprendizaje se procederá a describir el Proyecto de Intervención Autóno ma realizado en el Prácticum III.1. Dicho proyecto consistió en una propuesta global en la que participaron los alumnos/as , las familias y la ONG Samaritan’s Purse. Gracias al esfuerzo de todos e llos se consiguió enviar una donación para niños y niñas de Transilvania, región histórica de Rumanía. Uno de los objetivos del Proyecto d e Intervención Autónoma era conseguir que los alumnos y los de stinatarios de la donación se pusiesen en contacto entre ellos . Sin embargo, al no materializarse dicha conexión , s e sugiere que la propuesta de mejora planteada en el Proyecto de Intervención Educativa se realice de man e ra directa y sin utilizar la ONG como intermediario. En la propuesta se aborda el tema de las desigualdades del mundo a través de la reflexión sobre el hábito consumista de las sociedades occidentales . Asimismo, se analiza la influencia de la cultura visual de los alumnos en este fenómeno. Un aprendizaje cooperativo y en comunidad marcarán el desarrollo del proyecto , ya que se realizará de manera simu ltánea en el CEIP Jacaranda, situado en la provincia de Málaga, España , y en la Escuela Nº6 Juana Manso, ubicado en Lezama, provincia de Buenos Aires, Argentina. Las posibilidades de comparar los distintos contextos y de realizar intercambios de experienci as conseguirán que los alumnos analicen de manera crítica los hábito s de consumo actual

Yogur desnatado con transglutaminasa microbiana: evaluación de la aceptación del consumidor

The decrease in the fat content of yoghurt causes sensory modifications. Microbial transglutaminase (TG) has been proposed as an alternative for reducing the problems caused by the fat reduction. This work deals with the evaluation of the sensory profile, acceptance and preferences of skim yoghurt produced with TG at pilot scale. A group of 124 consumers of yoghurts were randomly selected. A lower firmness has been observed in yoghurt without TG (NoTG). TG Yoghurt has shown a lower whey odor and less acid taste than NoTG yoghurt. Free whey was not observed in the TG yoghurt. Despite of those differences, consumers only observed minor textural differences. In terms of overall acceptance and preference, no statistically significant differences were observed. The use of TG avoids the addition of milk protein or other texture additives into the yoghurt, decreasing production cost with the same overall acceptance and preference by consumers.La disminución del contenido graso del yogur provoca modificaciones sensoriales. La transglutami- nasa microbiana (TG) se ha propuesto como una alternativa para reducir los problemas causados por la reducción de grasa. Este trabajo trata sobre la evaluación del perfil sensorial, la aceptación y la preferencia del yogur desnatado producido con TG en una planta piloto. Un grupo de 124 consumidores de yogures fueron seleccionados al azar. Una menor firmeza se observó en el yogur sin TG (NoTG). EL yogur con TG mostró menor olor a suero, menor sabor ácido que el yogur NoTG. No se observó suero en el yogur con TG. A pesar de esas diferencias, los consumidores solo observaron pequeñas diferencias de textura. En términos de aceptación global y preferencia, no se observaron diferencias estadísticamente significativas. El uso de TG evita la adición de proteínas de la leche u otros aditivos para mejorar la textura del yogur, lo que reduce los costes de producción manteniéndose la aceptación y preferencia por parte de los consumidores.This research was supported by MICINN (Spain) [Project No. RTC2014- 1835-2] and Consellería de Cultura, Educación e Ordenación Universitaria, Xunta de Galicia (ES) [Project No. ED431B 2016/009]S

How Can Companies Decrease Salesperson Turnover Intention? The Corporate Social Responsibility Intervention

Salespeople turnover is a key issue that can threaten a company’s survival, either by reducing its income or increasing its expenses. The purpose of this study is to analyze the impact of corporate social responsibility (CSR) practices on the salespeople turnover. Drawing from social network theory, this research suggests that the perception of CSR practices influences salespeople turnover through their impact on the perception of the company’s reputation and the organizational pride that sellers experience. Additionally, the moderating role of interpersonal justice in the CSR-organizational pride relationship is analyzed. The data was collected from a sample of 176 salespeople and their supervisors from 96 companies. Structural equation modeling was used to analyze the psychometric properties of the measurement scales and to test the proposed direct hypotheses, and conditional process analysis was used to test the proposed mediation hypothesis. The results indicate that CSR is negatively related to salesperson turnover via the perceived salespeople’s organizational pride and organizational reputation. Furthermore, this study’s findings confirm the importance of a salesperson’s interpersonal justice for these relationships. This study contributes to the existing sales and management literature by enhancing our understanding of how to reduce salespeople turnover intention. Specifically, it underlines the role of CSR practices in reducing those intentionsThis research was funded by Galician Plan for Research, Innovation and Growth (Plan I2C) of the Xunta de Galicia (Consellería de Cultura, Educación y Ordenación Universitaria)S

Regulation of Ace2-dependent genes requires components of the PBF complex in schizosaccharomyces pombe

The division cycle of unicellular yeasts is completed with the activation of a cell separation program that results in the dissolution of the septum assembled during cytokinesis between the 2 daughter cells, allowing them to become independent entities. Expression of the eng1+ and agn1+ genes, encoding the hydrolytic enzymes responsible for septum degradation, is activated at the end of each cell cycle by the transcription factor Ace2. Periodic ace2+ expression is regulated by the transcriptional complex PBF (PCB Binding Factor), composed of the forkhead-like proteins Sep1 and Fkh2 and the MADS box-like protein Mbx1. In this report, we show that Ace2-dependent genes contain several combinations of motifs for Ace2 and PBF binding in their promoters. Thus, Ace2, Fkh2 and Sep1 were found to bind in vivo to the eng1+ promoter. Ace2 binding was coincident with maximum level of eng1+ expression, whereas Fkh2 binding was maximal when mRNA levels were low, supporting the notion that they play opposing roles. In addition, we found that the expression of eng1+ and agn1+ was differentially affected by mutations in PBF components. Interestingly, agn1+ was a major target of Mbx1, since its ectopic expression resulted in the suppression of Mbx1 deletion phenotypes. Our results reveal a complex regulation system through which the transcription factors Ace2, Fkh2, Sep1 and Mbx1 in combination control the expression of the genes involved in separation at the end of the cell division cycle

Construcción y evaluación de una estrategia comunicacional multiobjetivo para ámbitos de investigación científica : El caso del Observatorio de Movilidad Urbana de Gran La Plata

It´s evident, there’re difficulties in the communication between research groups and the community. This is reflected on the analysis of the communication platforms used by differents institutes and investigation centers. The complexity of the contents, presented without synthesis and systematization, remove to the general public from an accessibility to the knowledge of scientific production, so that could transform the life of the persons. Especially, the research groups works with topics of the city and the mobility, producing key knowledge about very daily topics for most of the urban population. These groups use to create communication platforms called mobility observatories on wich the communication strategy shines for her absence.El conocimiento de producción científica es muy valorado por sus potenciales aportes al desarrollo de los países, a la salud y a la calidad de vida de las personas. Sin embargo acceder a la comprensión de la producción científica requiere de un esfuerzo de comunicación particular desde el ámbito de la investigación, el cual no sucede con frecuencia. La evidencia de que existen dificultades en la comunicación entre grupos de investigación y la comunidad queda reflejado al revisar y analizar bajo criterios visuales las plataformas de comunicación utilizadas por distintos institutos y centros de investigación. La complejidad de contenidos abordados comunicados de maneras poco sintéticas y poco sistemáticas, apuntan a alejar al público en general de una accesibilidad al conocimiento de producción científica de manera que logre transformar la vida de las personas. En particular los grupos de investigación que trabajan con temas de la ciudad y la movilidad, producen conocimientos clave acerca de temas muy cotidianos para la mayor parte de la población urbana. Estos grupos suelen crear plataformas de comunicación llamados observatorios de movilidad urbana los cuales suelen procurar visibilidad y utilizar múltiples recursos gráficos que, por ausencia de estrategias de comunicación conlleva a la baja complementariedad del uso del color/equilibrio, de la forma/combinación, pero principalmente a la baja representación gráfica como recurso comunicacional. En este marco, la presentación pone en debate criterios y estrategias metodológicas a desarrollar para conseguir representar visualmente conceptos complejos y nociones simples, las nociones conceptualmente abstractas, propias de las temáticas investigadas que se necesita comunicar a la sociedad a través de estas plataformas. Para tal fin se toma como caso al Observatorio de Movilidad Urbana de Gran La Plata (IIPAC-FAU-UNLP-CONICET) y se expone el proceso de Comunicación Visual desarrollado abordado desde varias aristas, creando una estrategia comunicacional de 360º. Este trabajo implicó el desglose y análisis de información generada por el Observatorio de Movilidad del Gran La Plata, para luego canalizarla de manera gráfica a los potenciales usuarios, con el objetivo de dar a conocer al observatorio y sus investigaciones, elevando su renombre. Para el proyecto se generaron nuevos componentes, teniendo como estructura una base identitaria sólida, que responda a la esencia del observatorio. La canalización se llevó a cabo a través de la creación de una marca, la creación de una página web, la creación de piezas gráficas para impresión y para redes sociales, logrando diversificar la llegada a los diferentes usuarios. Como etapa final se elaboró un registro que evalúa el nivel de incidencia e impacto de las diferentes plataformas sociales de comunicación. Se intenta visibilizar la importancia de nuestra disciplina en ámbitos que requieren complejas estrategias de comunicación. “Se puede considerar a toda identidad como la relación que cada entidad mantiene consigo misma y con su entorno».

Psychometric properties of the spanish version of the pregnancy related anxiety questionnaire (PRAQ)

Although pregnancy increases the vulnerability to anxiety, no specific assessment instruments are usually used to detect it. The objective of this study was to adapt the Pregnancy Related Anxiety Questionnaire (PRAQ) to Spanish population, as well as analyze its validity and reliability. A sample of 367 nulliparous pregnant women with a normal risk status filled in a socio-demographic and obstetric-gynaecological questionnaire, the PRAQ, the Edinburgh Postnatal Depression Scale (EPDS) and the State-Trait Anxiety Inventory (STAI). After performing a factorial analysis, a five-factor model that explains 53.1% of the variance was obtained. Estimates of internal consistency reliability were adequate (range = .78 to .93) for the five factors included in the final confirmatory factor analysis, and for the total scale (.97). Significant correlation among PRAQ, EPDS, and STAI was found (p < .001). The 85th percentile (score 234 or more) was used as a cut-off point to identify those women with high pregnancy-specific anxiety. In accordance with the results obtained, the PRAQ can be considered a useful screening tool to evaluate pregnancy-related anxiety among the Spanish populationS

Valorization of citrus waste: use in catalysis for the oxidation of sulfides

The utilization and valorization of industrial waste is an effective strategy for environmental protection. Since the juice industry generates a huge amount of citrus waste, we studied the application of thermally treated orange peel in catalysis. On the other hand, Keggin heteropolyacids are excellent oxidant catalysts used as a replacement for conventional oxidants; however, their solubility in polar solvents and the low specific area limit their use as heterogeneous catalysts. The utilization of treated orange peel as heteropolyacid support for the selective oxidation of sulfides is presented here. Firstly, orange peel was thermally treated, and then it was incorporated with heteropolyacids (PMo) during the silica synthesis by the sol-gel method. Therefore, SiO2-PMo, SiO2-OP100-PMo, and SiO2-OP200-PMo were obtained, characterized by FTIR, SBET, XRD, and potentiometric titration, and were tested as heterogeneous catalysts in the selective oxidation of sulfide to sulfoxide in a greener process: H2O2 as oxidant and ethanol as solvent, at 25 °C.Centro de Investigación y Desarrollo en Ciencias Aplicada
