Risk assessment in ginecology and obstetrics in Sicily: an approach based on Wolff's Criteria
2013
Objectives To apply Wolff’s Criteria to hospital discharge records (HDR) in order to detect adverse events worthy of further study. Methods Gynecology and Obstetrics Units of three Sicilian hospitals were considered and HDR regarding ordinary and day hospital admissions in 2008 were collected. A matched case-control study was designed, by random selection of 10 controls at maximum for each case. Matching was performed on the variables age and speciality of admission (gynecology or obstetrics). Results Out of a total of 7011 HDR examined, 114 cases were identified with Wolff’s Criteria. Multivariate analysis confirmed a statistically significant association with the origin of admission, diag…
Improving on numerical simulations of nonlinear CMB anisotropies
2015
An Adaptative-Particle-Particle-Particle-Mesh code (HYDRA) plus a ray-tracing procedure was used in [1] to perform an exhaustive analysis of the weak lensing anisotropy. Other nonlinear Cosmic Microwave Background anisotropies, such as the Rees-Sciamaand the Sunyaev-Zel.dovicheffects are also being studied by using the same tools. Here we present some advances in our study of these nonlinear anisotropies. The primary advance is due to the use of better simulations with greater particle densities and appropriate softening, although other parameters have also been adjusted to get better estimates. Thus, we improve on a previous paper [2] where the Rees-Sciamaeffect was studied with Particle-M…
Test-Bed Evaluation of CA and CF via a Software Defined Radio
2019
In Chaps. 3 and 4, we presented the analytical models and simulation approaches to study the impact of CA and CF on traffic flows in the single-flow single-user and the single-flow multi-user systems. In this chapter, we investigate the impact of CA and CF in a test-bed. We employ a software defined radio (SDR) from National Instruments (NI) to evaluate the performance of a CR system with user datagram protocol (UDP) flows. The adopted SDR is based on LTE protocol stack with additional functionalities that can support CA and CF, and accommodating PUs. By conducting measurements based on the test-bed system, we will be able to confirm that performance improvement can indeed be obtained by ap…

A Dynamic Viewpoint to Design Performance Management Systems in Academic Institutions: Theory and Practice
2014
This article illustrates how to design and apply Performance Management systems in academic institutions by identifying and modeling those factors affecting academic performance through a dynamic performance management view. Particularly, combining performance management with System Dynamics modeling may allow academic decision-makers to better identify key performance drivers for pursuing a sustainable performance improvement in universities. In the second section of the article, a number of examples based on empirical findings from a field project aimed at designing a dynamic performance management model for the University of Palermo (Italy) are discussed.
Self-improvement of pointwise Hardy inequality
2019
We prove the self-improvement of a pointwise p p -Hardy inequality. The proof relies on maximal function techniques and a characterization of the inequality by curves.
Self-improvement of weighted pointwise inequalities on open sets
2020
We prove a general self-improvement property for a family of weighted pointwise inequalities on open sets, including pointwise Hardy inequalities with distance weights. For this purpose we introduce and study the classes of $p$-Poincar\'e and $p$-Hardy weights for an open set $\Omega\subset X$, where $X$ is a metric measure space. We also apply the self-improvement of weighted pointwise Hardy inequalities in connection with usual integral versions of Hardy inequalities.
A maximal Function Approach to Two-Measure Poincaré Inequalities
2018
This paper extends the self-improvement result of Keith and Zhong in Keith and Zhong (Ann. Math. 167(2):575–599, 2008) to the two-measure case. Our main result shows that a two-measure (p, p)-Poincare inequality for $$10$$ under a balance condition on the measures. The corresponding result for a maximal Poincare inequality is also considered. In this case the left-hand side in the Poincare inequality is replaced with an integral of a sharp maximal function and the results hold without a balance condition. Moreover, validity of maximal Poincare inequalities is used to characterize the self-improvement of two-measure Poincare inequalities. Examples are constructed to illustrate the role of t…
Acoso escolar y Educación Física: una revisión sistemática (Bullying in schools and Physical Education: A systematic review)
2018
El objetivo de este trabajo es realizar una revisión sistemática de estudios sobre acoso escolar y Educación Física (EF). Se identifican, categorizan y analizan los artículos señalando sus características y sintetizando los principales temas de investigación y su contenido. Para ello, se ha consultado la base de datos Web of Science®. Se seleccionaron un total de 19 artículos científicos. Respecto al análisis documental, se presentan hallazgos sobre revistas más productivas, autores e instituciones con mayor actividad investigadora en este campo y metodología de investigación utilizada en los estudios encontrados. Además, se hace un análisis cualitativo centrado en el contenido de los 4 tem…
Patterns of Safety Incidents in a Neonatal Intensive Care Unit
2021
Introduction: Safety incidents preceding manifest adverse events are barely evaluated in neonatal intensive care units (NICUs). This study aimed at identifying frequency and patterns of safety incidents in our NICU.Methods: A 6-month prospective clinical study was performed from May to October 2019 in a German 10-bed level III NICU. A voluntary, anonymous reporting system was introduced, and all neonatal team members were invited to complete paper-based questionnaires following each particular safety incident. Safety incidents were defined as safety-related events that were considered by the reporting team member as a “threat to the patient's well-being” which “should ideally not occur agai…
