Relation of fruit color, elongation, hardness, and volume to the infestation of olive cultivars by the olive fruit fly, Bactrocera oleae
2012
The susceptibility of olive cultivars to the olive fruit fly, Bactrocera oleae (Rossi) (Diptera: Tephritidae), has seldom been studied. This article examines factors associated with olive fruit fly infestation of 16 commonly planted Sicilian olive cultivars. Total infestation data were simultaneously correlated with categorical and quantitative factors using ordinal logistic regression. When all factors were included in the analysis, year, sampling date, cultivar, and fruit color were highly significant, but the quantitative factors fruit volume, fruit elongation, and fruit hardness were not. When the analysis was repeated excluding cultivar, all quantitative factors were significant, and e…
Bivariate logistic models for the analysis of the students' University "success"
2012
We analyze the students’ success at University by considering their performance in terms of both “qualitative performance”, measured by their grade average, and “quantitative performance”, measured by University Credits accumulated. To jointly model both marginal and association relationships with covariates, the analysis has been carried out by fitting a bivariate ordered logistic model (BOLM), in a nonparametric fashion, by penalized maximum likelihood estimation. The advantages of such model are in terms of parsimony and parameters interpretation, while preserving goodness-of-fit. The application regards an engineering student (ES) cohort from the University of Palermo.
Sexual behaviors and function during menopausal transition—does menopausal hormonal therapy play a role?
2020
Objectives: The menopausal transition is a biological adaptation to the variety of life changes (body, comorbidities, relationship), but that biology is not an “end all” in the context of sexual function and overall sexual health. The aim of this study is to evaluate determinants altering the risk of female sexual dysfunction (FSD) and other sexual problems and to establish whether menopausal hormonal therapy (MHT) decreases that risk and modifies sexual behaviors. Methods: A cross-sectional observational study was conducted in 210 women between the ages of 45 and 55. Two groups were identified: MHT users (n = 107) and controls—MHT non-users (n = 103). Diagnostic and Statistical Manual of M…
Prevalence of endodontic infection in patients with Crohn ́s disease and ulcerative colitis
2021
[Background] Previous studies have linked apical periodontitis (AP) to inflammatory bowel disease (IBD). The aim of this study was to compare the prevalence of AP and root canal treatment (RCT) in patients with ulcerative colitis (UC) and Crohn ́s disease (CD).
Health-related correlates of psychological well-being among girls and boys 6-8 years of age: The Physical Activity and Nutrition in Children study
2018
AIM Due to limited knowledge on the differences in the correlates of psychological well-being (PSWB) between girls and boys, we compared the correlates of PSWB between primary school girls and boys. METHODS A population sample of 412 children participated in the Physical Activity and Nutrition in Children study. Parents completed a questionnaire that included 19 questions on the components of PSWB, and a PSWB score was computed. We assessed correlates of PSWB, including physical activity, sedentary behaviour, cardiorespiratory fitness, diet quality, body fat content, sleep duration, sleep disordered breathing, prevalent diseases and parental characteristics. We used logistic regression to a…
Dental pain associated with untreated dental caries and sociodemographic factors in 5-year-old children
2020
Background The aim of this study was to assess the prevalence of dental pain and to examine its association with untreated dental caries in 5-year-old children. Material and Methods This was a cross-sectional study of 261 5-year-old children in Northeast Brazil. Parents answered questions about their socioeconomic conditions and their children's toothache. Trained dentists assessed dental caries using the decayed, missing and filled teeth (dmf-t) index. Binary logistic regression models were used to estimate the unadjusted and adjusted odds ratios (ORs) and the confidence intervals (95% CIs) for the association of dental pain with covariates. The significance level was set at five percent. …
TCH-039 Six Sigma in Healthcare: An Application in the Monitoring of Albumin
2013
Background The high off-label use of albumin persuaded the pharmacy to introduce a request form that uses the internationals guidelines to assess whether the use of albumin is appropriate. This has resulted in a clear reduction in the costs. Purpose To monitor the wards using six sigma methodology (a statistical concept that measures a process in terms of defects); to ensure that all procedures have been followed correctly. Materials and Methods 696 forms for albumin prescriptions coming from 26 wards (August to December 2011) were analysed using Minitab software, which cheques the frequency of the best correct requests (type 1), partially correct requests (type 2) and incorrect requests (t…
The Role of the Integrated Public Transport Network for Reducing the Congestion in the City of Palermo
2019
The railway link of Palermo is part of the Palermo – Trapani railway line and it is located in the urban site of Palermo. Works funded by the European Union have been started in 2008 for developing a metropolitan service through the improvement of the infrastructure and of the transport service characteristics. The aim of the paper is the analysis of the capacity of the railway infrastructure in terms of frequency and integration with the public transport service of Palermo. Using the Origin-Destination matrix of the Urban Transport Plan of Palermo, the competition between the private car mode and the public transport mode has been simulated, taking into account the improving of the railway…
Cooperation Formats of China and Europe: Synergies and Divergences
2017
Abstract This contribution articulates the synergies and divergences of the various formats of cooperation between China and the European countries. The EU and China have a strong interest in each other’s flagship initiatives, namely the Investment Plan for Europe, and the One Belt, One Road Initiative (Silk Road Economic Belt and 21st-Century Maritime Silk Road). The authors argue that there are certain synergies between these initiatives. Furthermore, the new initiative EU-China Connectivity Platform is aimed to explore these synergies. The authors explore the recent developments in the EU-China investments, trade cooperation and the challenges of the ever-growing CEEC-China partnership i…
Microstructure and rheological response of laboratory-aged SBS-modified bitumens
2019
Polymer additives are widely used to improve the performance of road bitumens including their resistance to hardening during oxidation, although their oxidative inhibitor effect has not been well documented. This study aims to investigate the effect of laboratory-simulated ageing on the microstructure, and rheological properties of Polymer Modified Bitumens (PMBs) prepared with a Styrene-Butadiene-Styrene (SBS) copolymer and sulphur as a cross-linker. The laboratory ageing was conducted through the Rolling Thin Film Oven (RTFO) and the Pressure Aging Vessel (PAV) procedures. The unaged and aged binders were characterised using the Multiple Stress Creep and Recovery (MSCR) test, Gel Permeati…
