Postharvest Application of Sulphur Dioxide Fumigation to Improve Quality and Storage Ability of "Red Globe" Grape Cultivar During Long Cold Storage
2017
Table grape cv 'Red Globe' is produced in Sicily and in other areas of Southern Italy. This produce is very appreciated by consumers, having the best rankings in the world market for exports and quality. Nevertheless, despite it is a non-climacteric fruit, table grape is very perishable, both after harvest, and during postharvest handling and cold storage. In fact, also at low temperatures, table grape is very sensitive to fungal infection (Botrytis cinerea) and other diseases, like gray mold, which is very aggressive. For this reason, a standard practice is to fumigate table grape with sulphur dioxide (SO2), after storage in chambers. The growing market request of table grape cv. 'Red Glob…
TESF Methodology for Statistics Education Improvement
2010
The need for universities to achieve excellence in the services they provide has been the subject of research for several decades. The idea of involving students and recognizing the importance of their opinions has led to the creation of various models and tools. This paper focuses on teaching, a central service from which improvement actions of an academic institution should always begin. The article reviews and updates the previously developed Teaching Experiments and Student Feedback methodology. The methodology, which is primarily addressed to statistics teachers, allows practical aspects to be organized and decisions to be made based on data that has been collected from students and sc…
Evaluating the effect of organization and context on technical efficiency: a second-stage DEA analysis of Italian hospitals
2022
Objective: the purpose of this study was to compare the technical efficiency of Italian hospitals at a regional level and to examine if differences could be explained by organisational and contextual factors. Technical efficiency was defined as the ability of the operating units evaluated to use optimal resource levels for their level of output.Methods: the effect of external factors was explored through a second stage Data Envelopment Analysis (DEA). Efficiency scores were calculated for each hospital using the DEA method (Stage I). Through Tobit regression analysis, the estimated efficiency scores were regressed against a set of organisational and contextual characteristics beyond manager…
Nuclear Magnetic Resonance with Fast Field-Cycling Setup: A Valid Tool for Soil Quality Investigation
2020
Nuclear magnetic resonance (NMR) techniques are largely employed in several fields. As an example, NMR spectroscopy is used to provide structural and conformational information on pure systems, while affording quantitative evaluation on the number of nuclei in a given chemical environment. When dealing with relaxation, NMR allows understanding of molecular dynamics, i.e., the time evolution of molecular motions. The analysis of relaxation times conducted on complex liquid–liquid and solid–liquid mixtures is directly related to the nature of the interactions among the components of the mixture. In the present review paper, the peculiarities of low resolution fast field-cycling (FFC) NMR rela…
Comparing Aspects Of The Process Quality In Six European Early Childhood Educational Settings
2013
The European project ‘Early Change’ (http://earlychange.teithe.gr) attempts to evaluate the quality of early childhood education (ECE) environments of six European countries, Greece, Portugal, Finland, Denmark, Cyprus and Romania. The purpose of this paper is to compare the level of two dimensions of the process quality of these environments a) Space & Furnishings, and b) Personal Care Routines. Theorists, practitioners and researchers agree that in order to provide qualitative education to young children, one of the basic needs of all children must be met; that need is the protection of their health and their safety. A high quality early childhood education program must contain a safe and …
Using the Rasch model to assess a University Service on the Basis of Students Opinions
2008
In this paper we use the Rasch model (RM) as a tool to measure the perceived quality of student services at the Reception Office of an Italian university faculty. This paper has both a substantive and a methodological aim. The former is concerned with measuring the service quality of the Reception Office, while the latter concerns the definition and validation of an instrument for measuring perceived quality. The sample comprised 273 students enrolled at the Faculty of Economics at the University of Palermo (Aiello F. Il modello di Rasch per la costruzione di uno strumento di misura della qualit`a di un Servizio. Ph.D. Thesis, University of Palermo, Palermo, 2005). The RM is applied to prod…

Enhanced TESF methodology for course excellence
2010
The need to achieve the excellence in services provided by a University has been object of study and research for several decades. Often, the focus is not only on the education service, but on several satellite services provided by a university. This article focuses on teaching, considered as a central service, believing (the authors) that the improvement actions of an academic institution should always start from this service. The work proposes the implementation of a tool able to measure student perceptions on certain selected aspects of the course. This tool is part of the Teaching Experiment and Student Feedback (TESF) methodology previously developed by the authors. Here, the steps to …
Information quality evaluation methodology for web page directories
2016
The article presents information quality evaluation methodology for websites directories. In the first part of the article the theoretical basis for website directories was presented (ways of information acquisition, classification and issues relating to quality of websites). The second part of the article was devoted to the research methodology for evaluating quality of information collected in website directories. The identification of quality characteristics carried out shall allow for evaluating quality of general information and of information in thematic directories on web pages. The article ends with a summary containing conclusions and guidelines for further research directions.
