STUDENTS' EVALUATIONS OF UNIVERSITY TEACHING: A STRUCTURAL EQUATION MODELING ANALYSIS

In this paper a Student Satisfaction survey was conducted. The used questionnaire was proposed by a very large Research Group in 2010. The collected data was elaborated by a full reflective Structural Equation Model using PLS path model estimation. The first results showed that the influence of the Organization and Infrastructure on the Student Satisfaction were not statistically significant. Therefore a more complex model was supposed, the end results showed that the influence of Organization and Infrastructure on the SS was indirect, that is the Organization and the Infrastructures exert an influence upon the SS through the Didactics

Three-way Decomposition of Weighted Log-odds Ratio for Customer Satisfaction Analysis

In literature several methods have been proposed for the service quality assessment. A large number of models have been proposed to evaluate Service Quality (Servqual, Normed Quality, Servperf etc.). Starting from the SERVPERF paradigm, in this paper we propose to use Odds Ratio analysis to evaluate Customer Satisfaction. In particular the data has been collected in three-way contingency tables in which the crossed variables are perception evaluations, importance evaluations and dimensions. For each slice we computed the Odds Ratio. Thus a weighted version of log-Odds Ratio Analysis for three-way is proposed and analyzed by the Parafac/Candecomp algorithm. A case study on Patient Satisfaction (PS) survey that was carried out at a Neapolitan government hospital is presented in the last part of the paper in order to show the proposed methods

Generalized log odds ratio analysis for the association in two-way contingency table.

The odds ratio is a measure of association used both for the analysis of a contingency table and an contingency table, where I and J are bigger than 2. Nevertheless, the total number of odds ratios to check grows with I and J and several methods have been developed to summarize them. In the present paper we present a general framework for the analysis of the complete set of log odds ratio. Particularly we propose and connect two different methodologies performed on two different data sets. Moreover starting from these methodologies, we focus our attention on the factorial representation of the log odds ratios

Alcune considerazioni sull’analisi multidimensionale dei dati nella valutazione dei servizi di day surgery

The evaluation of the quality on the Day Surgery service is an actual problem. The conceptual models proposed in literature allow to collected data of the different nature: ordinal, compositional, and so on. The multidimensional analysis of these data gives more problems and difficulties. Aim of this paper is to think about the mentioned problems as well as to suggest suitable multidimensional methods. Finally, the appropriateness of the inclusion the external information in a customers satisfaction framework is given

Timing chirurgico nell’adenoma epatico sanguinante: case report

La diagnosi di adenoma epatico, la cui eziopatogenesi è spesso un rapporto con l’assunzione prolungata di estroprogestinici (il 90% degli adenomi si osserva in donne che hanno preso la ‘pillola’ per più di 5 anni), impone sempre una indicazione chirurgica resettiva. La ragione è data dalle caratteristiche peculiari della neoplasia, che sono la degenerazione maligna (4%) e l’elevato rischio di sanguinamento (30- 50%), intratumorale e/o intraaddominale, che aumenta in gravidanza e in puerperio. La regressione dopo sospensione della terapia ormonale, infatti, è poco frequente e non elimina il rischio di degenerazione e/o emorragia. La resezione epatica dovrebbe essere condotta in combinazione con appropriate procedure di embolizzazione endovascolare selettiva, considerato che la chirurgia in emergenza potrebbe imporre un sacrificio epatico maggiore, esponendo il paziente a morbilità e mortalità più elevate. I tempi di attesa dall’embolizzazione all’intervento elettivo non sono standardizzati e sono pertanto indicati dall’esperienza personale e soprattutto da un attento e seriato follow-up del paziente. Gli Autori riportano la propria esperienza nella strategia terapeutica e nel timing chirurgico di un caso di adenoma epatico sanguinante
