Managing satisfaction in cultural events: Exploring the role of core and peripheral product
2017
1.INTRODUCTIONSatisfaction is a key concept within the marketing discipline and specifically within the area of consumer behaviour. Satisfaction in the arts is mostly derived from a combination of three elements: the subjective and experiential aspects of the cultural product, the quality of the venue and the quality of the associated peripheral services (Hume, 2008a). According to this author, studies on satisfaction with cultural events are key to understanding customer motives to repurchase subscription which can increase the arts organization's profitability, this being a main goal of the currently complex entertainment arena.This study focuses on satisfaction among visitors of an art e…
School adjustment in children who stutter: The quality of the student-teacher relationship, peer relationships, and children's academic and behaviora…
2020
Abstract Introduction The aim of this study was to investigate the quality of the student-teacher relationship, peer relationship, emotional and behavioral outcomes and academic performance in school adjustment of children who stutter. Methods The convenience sample consisted of 536 children – 62 affected by stuttering and 474 in the control group – and 36 prevalent teachers from six primary and secondary schools in Northwest Italy. Children were assessed with a sociometric questionnaire. Teacher evaluations were also used to assess their perception of their relationships with the student (Student-Teacher Relationship Scale), children’ behavior (Strengths and Difficulties Questionnaire), an…
An infrared spectroscopic tool for process monitoring: sugar contents during the production of a depilatory formulation.
2012
Abstract A fast, reliable and economical methodology has been developed to control the production process of sugar-based depilatories. The method is based on the use of attenuated total reflectance—Fourier transform infrared (ATR-FTIR) spectroscopy in combination with multivariate data analysis. A very simple sample preparation process involving the dissolution of samples in water was applied. Employing a multivariate calibration model established from data of 15 well characterized samples, prediction errors equal or below 3.04 mg mL−1 for the quantitative determination of fructose, glucose, sucrose, maltose and maltotriose were obtained. Results found in this preliminary study indicate a g…
The reporting of study and population characteristics in degenerative cervical myelopathy: A systematic review
2017
OBJECT: Degenerative cervical myelopathy [DCM] is a disabling and increasingly prevalent condition. Variable reporting in interventional trials of study design and sample characteristics limits the interpretation of pooled outcomes. This is pertinent in DCM where baseline characteristics are known to influence outcome. The present study aims to assess the reporting of the study design and baseline characteristics in DCM as the premise for the development of a standardised reporting set. METHODS: A systematic review of MEDLINE and EMBASE databases, registered with PROSPERO (CRD42015025497) was conducted in accordance with PRISMA guidelines. Full text articles in English, with >50 patients (p…

El actual contexto educativo necesita una intensa alfabetización digital de todo el profesorado, lo que ha requerido una modificación significativa en los perfiles docentes convencionales. En el caso del profesorado especialista en Pedagogía terapéutica que trabaja con alumando con necesidades educativas especiales, la digitalización ha supuesto un desafío. Tales cambios han requerido dotarse de nuevas habilidades para transformar la información en conocimientos, guiar el proceso de enseñanza aprendizaje en un entorno novedoso y generar un espacio de inclusión educativa. El objetivo de esta investigación es identificar cuáles son los perfiles de los profesionales especialistas en Pedagogía …
How Can the COVID-19 Pandemic Lead to Positive Changes in Urology Residency?
2020
The COVID-19 outbreak, in a few weeks, overloaded Italian hospitals, and the majority of medical procedures were postponed. During the pandemic, with hospital reorganization, clinical and learning activities performed by residents suffered a forced remodulation. The objective of this study is to investigate how urology training in Italy has been affected during the COVID-19 era. In this multi-academic study, we compared residents' training during the highest outbreak level with their previous activity. Overall 387 (67.1%) of the 577 Italian Urology residents participated in a 72-h anonymous online survey with 36 items sent via email. The main outcomes were clinical/surgical activities, soci…
Boceprevir is highly effective in treatment-experienced hepatitis C virus-positive genotype-1 menopausal women
2014
AIM: To investigate the safety/efficacy of Boceprevirbased triple therapy in hepatitis C virus (HCV)-G1 menopausal women who were historic relapsers, partial-responders and null-responders. METHODS: In this single-assignment, unblinded study, we treated fifty-six menopausal women with HCV-G1, 46% F3-F4, and previous PEG-α/RBV failure (7% null, 41% non-responder, and 52% relapser) with 4 wk lead-in with PEG-IFNα2b/RBV followed by PEGIFNα2b/RBV+Boceprevir for 32 wk, with an additional 12 wk of PEG-IFN-α-2b/RBV if patients were HCV-RNA-positive by week 8. In previous null-responders, 44 wk of triple therapy was used. The primary objective of retreatment was to verify whether a sustained virolo…
A multivariate insight into ionic liquids toxicities
2014
A multivariate insight into Ionic Liquids' (ILs) toxicity, a broad term highly dependent on the biological systems adopted as “sensors”, addressed four main groups of toxicities: aquatic toxicity, toxicity towards fungi and bacteria, cytotoxicity towards IPC-81 rat cell lines and acetylcholinesterase enzyme inhibition. This approach, summarizing toxicity information available from a huge amount of scattered literature data, allowed derivation of aquatic toxicity scores for 104 ILs and bacteria and fungi toxicity scores for 87 ILs as well as identification of a correlation between aquatic ecotoxicity and the response of IPC-81 rat cell lines. Further evidence on the effects of cation structu…
Effect of two antihypertensive combinations on metabolic control in type-2 diabetic hypertensive patients with albuminuria: a randomised, double-blin…
2001
The objective of this study was to compare, at equal blood pressure (BP) reduction, the effect of two different combinations on metabolic control and albuminuria in type 2 diabetic hypertensive patients with albuminuria. This was a prospective, randomised, double-blind, parallel, controlled trial carried out in 11 Spanish hospitals. A total of 103 type 2 diabetic patients with stable albuminuria and BP not controlled on monotherapy were randomised of which 93 finished the study. After a 4-week single-blind placebo period, patients were randomised to verapamil SR/trandolapril 180/2 mg (VT) or to enalapril/hydroclorothiazide 20/12.5 mg (EH). Treatment duration was 6 months. The main outcome m…
Expanded criteria for liver transplantation in patients with cirrhosis and hepatocellular carcinoma
2008
Orthotopic liver transplantation (OLT) selection for patients with hepatocellular carcinoma (HCC) is a matter of debate. The Milan criteria (MC) have been largely adopted by the international community. The main aim of this study was to evaluate the survival rates and recurrence probabilities of a new proposal for criteria (up to 3 tumors, each no larger than 5 cm, and a cumulative tumor burden </= 10 cm). Patients with cirrhosis and HCC included on the waiting list (WL) from 1991 to 2006 were retrospectively analyzed. Outcomes in patients who had tumors within and beyond the MC were compared. The survival analysis was done (1) with the intention-to-treat principle and (2) among transplante…
