Psychometric properties of the Iranian version of the premature ejaculation diagnostic tool

Introduction Premature ejaculation (PE) is one of the most prevalent male sexual problems. The Premature Ejaculation Diagnostic Tool (PEDT) is a suitable patient-reported outcome measure for the assessment of PE. Aim To examine the psychometric proporties of a translated and culturally adapted version of the PEDT in a sample of Iranian men suffering from PE. Methods Two independent samples were compared, one including patients with PE based on the DSM-IV-TR criteria (n = 269) and the other including healthy men without PE (n = 289). A backward–forward translation procedure was used to translate the PEDT into Persian. Both samples were asked to fill in the PEDT twice—at baseline and 4 weeks later. Main Outcome Measures Internal consistency, test–retest reliability, convergent validity, factor structure, measurement invariance across sexual health status (i.e., between men with and without PE). Results Mean ages of men without and with PE were 34.9 and 35.3 years, respectively. Cronbach's alpha coefficient for the total PEDT score was 0.89. All items and the total score were remarkably consistent between the two measurement points. All five PEDT items correlated at r = 0.40 or greater with their own scale, indicating good convergent validity. There was a high and significant correlation (r = −0.82, P  < 0.001) between the PEDT score and IELT. Healthy men reported lower scores (fewer complaints) on the PEDT compared with the PE group. A single-factor model was found to be best-fitting in the exploratory factor analysis; this was confirmed by confirmatory factor analysis. The PEDT was invariant across sexual health status and perceived similarly by men with and without PE. Conclusion The results provide evidence for good reliability and validity of the Iranian version of the PEDT. The questionnaire therefore represents a suitable tool for screening PE in Iranian men.

Managing large-enrollment courses in hybrid instruction mode

This essay addresses the hitches and glitches in the hybrid instruction system of teaching and learning for large-enrollment courses. This new instructional methodology asks facilitators to redesign their entire traditional teaching and learning practices. The nature of subject to be taught via the hybrid mode further affects the success rate of the modules from the time of inception to launch to actual delivery and completion of the course. The entire process involves undoing the old habits and methodologies and instructors picking up new skills, along with the right motivation to take up the task. The course planning and delivery require a substantial commitment in terms of hours from the instructors catering to large-enrollment courses, along with pursuing their routine roles at the campuses. From the pupil’s perspective, the response varies, as hybrid learning seeks self-discipline and time management skills from the learner. After the initial roadblocks, students enjoy hybrid learning if the course structure and instructions are simple and the course content flexible and varied. We will study the problems and possible solutions to the success of the hybrid teaching–learning system at each stage where large number of students enrolled for a specific course.

Mediante un modelo de regresión lineal, se encuentra un efecto adverso de la presencia de choques sobre el puntaje de la prueba Saber 11. Además, los resultados sugieren que el trabajo infantil es un mecanismo por el cual los choques afectan negativamente la acumulación de capital humano. Al explorar efectos heterogéneos por sexo y edad, las estimaciones indican que el efecto de los choques es guiado por los hombres y los adolescentes mayores a 14 años.

Acoso laboral y sus efectos en la salud del trabajador : revisión de la literatura

Introducción: Desde los años 80 se viene haciendo énfasis en el acoso laboral, conocido en otros países como Mobbing, describiéndose como una forma de abuso y violencia psicológica en el lugar de trabajo, realizado ya sea por una sola persona o por un grupo de personas y que por sus implicaciones se estima de alto impacto para los trabajadores, y las organizaciones. Considerando la importancia y prevalencia del mobbing en la sociedad actual, se convierte en un tema relevante para el área de salud ocupacional. Objetivo: El objetivo de este estudio fue identificar los efectos del acoso laboral generados en la salud del trabajador. Metodología: Se realizó una revisión sistemática utilizando el método PRISMA, de las publicaciones vigentes entre los años 2006 a 2016 sobre los efectos del acoso laboral en la salud del trabajador. En la búsqueda se obtuvieron 778 artículos de los cuales 27 cumplían con los criterios de inclusión. Resultados: se encontró que la prevalencia del acoso laboral puede ser diferente de acuerdo a la definición utilizada, instrumento de medida y población estudiada, la cual fluctúa entre el 7% al 88% según el estudio analizado. Además se evidenció que la prevalencia también difiere dependiendo de quién sea el perpetrador del acoso, si el líder o jefe es el acosador es mayor (60,3%) que cuando es causado por colegas o por clientes (41,5%). El impacto del acoso laboral, según la mayoría de los estudios, es que provoca efectos negativos en la salud emocional del trabajador siendo la depresión una de las principales consecuencias con una relación estadísticamente significativa (p<0,001). Las enfermedades del aparato respiratorio y del sistema musculo esquelético y del tejido conectivo fueron las que se presentaron con mayor frecuencia en los trabajadores que sufren de acoso con un 43,5% y un 37.8% respectivamente. Conclusiones: éstos resultados demuestran que el acoso laboral no solamente es un problema desde el punto de vista organizacional, sino que conlleva consecuencias en la salud mental y física de los trabajadores que lo sufren. Palabras clave: Mobbing, workplace, acoso laboral, acoso psicológico, bullying, harassment, salud ocupacional, occupational health.

Irrigation management with remote sensing: Evaluating irrigation requirement for maize under Mediterranean climate condition

tWater use control methods and water resources planning are of high priority. In irrigated agriculture, theright way to save water is to increase water use efficiency through better management. The present workvalidates procedures and methodologies using remote sensing to determine the water availability in thesoil at each moment, giving the opportunity for the application of the water depth strictly necessaryto optimise crop growth (optimum irrigation timing and irrigation amount). The analysis is applied tothe Irrigation District of Divor, Évora, using 7 experimental plots, which are areas irrigated by centre-pivot systems, cultivated to maize. Data were determined from images of the cultivated surface obtainedby satellite and integrated with atmosphere and crop parameters to calculate biophysical indicatorsand indices of water stress in the vegetation—Normalized Difference Vegetation Index (NDVI), Kc, andKcb. Therefore, evapotranspiration (ETc) was estimated and used to calculate crop water requirement,together with the opportunity and the amount of irrigation water to allocate. Although remote sensingdata available from satellite imagery presented some practical constraints, the study could contribute tothe validation of a new methodology that can be used for irrigation management of a large irrigated area,easier and at lower costs than the traditional FAO recommended crop coefficients method. The remotesensing based methodology can also contribute to significant saves of irrigation water.

Advanced voxel-based CAD modelling for FSI simulations for automotive structures design

Additive Manufacturing (AM) is nowadays considered an important alternative to traditional manufacturing processes. AM technology shows several advantages in literature as design flexibility, and its use increases in automotive, aerospace and biomedical applications. As a systematic literature review suggests, AM is sometimes coupled with voxelization, mainly for representation and simulation purposes. Voxelization can be defined as a volumetric representation technique based on the model’s discretization with hexahedral elements, as occurs with pixels in the 2D image. Voxels are used to simplify geometric representation, store intricated details of the interior and speed-up geometric and algebraic manipulation. Compared to boundary representation used in common CAD software, voxel’s inherent advantages are magnified in specific applications such as lattice or topologically structures for visualization or simulation purposes. Those structures can only be manufactured with AM employment due to their complex topology. After an accurate review of the existent literature, this project aims to exploit the potential of the voxelization algorithm to develop optimized Design for Additive Manufacturing (DfAM) tools. The final aim is to manipulate and support mechanical simulations of lightweight and optimized structures that should be ready to be manufactured with AM with particular attention to automotive applications. A voxel-based methodology is developed for efficient structural simulation of lattice structures. Moreover, thanks to an optimized smoothing algorithm specific for voxel-based geometries, a topological optimized and voxelized structure can be transformed into a surface triangulated mesh file ready for the AM process. Moreover, a modified panel code is developed for simple CFD simulations using the voxels as a discretization unit to understand the fluid-dynamics performances of industrial components for preliminary aerodynamic performance evaluation. The developed design tools and methodologies perfectly fit the automotive industry’s needs to accelerate and increase the efficiency of the design workflow from the conceptual idea to the final product.

Non-standard signatures from Cosmic Microwave Background polarisation

In this Thesis we focus on non-standard signatures from CMB polarisation, which might hint at the existence of new phenomena beyond the standard models for Cosmology and Particle physics. With the Planck ESA mission, CMB temperature anisotropies have been observed at the cosmic variance limit, but polarisation remains to be further investigated. CMB polarisation data are important not only because they contribute to provide tighter constraints of cosmological parameters but also because they allow the investigation of physical processes that would be precluded if just the CMB temperature maps were considered. We take polarisation data into account to assess the statistical significance of the anomalies currently observed only in the CMB temperature map and to constrain the Cosmic Birefringence (CB) effect, which is expected in parity-violating extensions of the standard electromagnetism. In particular, we propose a new one-dimensional estimator for the lack of power anomaly capable of taking both temperature and polarisation into account jointly. With the aim of studying the anisotropic CB we develop and perform two different and complementary methods able to evaluate the power spectrum of the CB. Finally, by employing these estimators and methodologies on Planck data we provide new constraints beyond what already known in literature. The measure of CMB polarisation represents a technological challenge and to make accurate estimates, one has to keep an exquisite control of the systematic effects. In order to investigate the impact of spurious signal in forthcoming CMB polarisation experiments, we study the interplay between half-wave plates (HWP) non-idealities and the beams. Our analysis suggests that certain HWP configurations, depending on the complexity of Galactic foregrounds and the beam models, significantly impacts the B-mode reconstruction fidelity and could limit the capabilities of next-generation CMB experiments. We provide also a first study of the impact of non-ideal HWPs on CB.
