Squilibri del mercato del lavoro e ricerca del personale

2017

Quando l’economia di un paese tende all’espansione o alla contrazione della ricchezza ciò si riflette sul mercato del lavoro determinando un impatto sull’occupazione e sui processi di ricerca del personale. Scopo di questo articolo è indagare le relazioni che intercorrono fra ricerca del personale e squilibri del mercato del lavoro nelle diverse condizioni di sviluppo del contesto macroeconomico. I risultati della ricerca mostrano che nei cicli di espansione dell’economia e della occupazione i datori di lavoro tendono ad adottare comportamenti di ricerca più attivi, formali, competitivi, mirati e selettivi. Viceversa nei cicli di contrazione dell’economia e dell’occupazione i datori di lavo…

Design and analysis of discrete choice experiments for models with response time

2013

Settore SECS-S/02 - Statistica Per La Ricerca Sperimentale E TecnologicaA sector of conjoint analysis (experimental design in marketing research) is made of the so called choice experiments. In choice experiments respondents undergo a questionnaire which is nowadays mostly submitted through the internet. The questionnaire proposes to the respondent a sequence of choice sets each one including two or more profiles being a profile a specific combination of attribute levels. The respondent selects the preferred profile for each choice set. Responses given by a sample of respondents are analysed through suitable methods aimed to eventually find the best combination of attribute levels. One method of analysis adopts the Multinomial Logit (MLN) model. In this article the authors show the results of the MLN analysis compared with another model of analysis which uses an additional response which can be easily recorded by electronically submitted questionnaires. In practice modern survey platforms like “Qualtrics” (the one used for this work) can record the so called “response latency” i.e. the time taken by the respondent to make the choice and select the most preferred profile in the choice set. Thanks to a response latency model further refined in this work it is possible to deduce the relative weight of importance of the profiles for each choice set and respondent. This type of response can be used in place of the dichotomous choice variable in the MLN model. The two models and methods of analysis are deeply compared and it is critically discussed when it is better to use one or the other method. As a result a more reliable estimate of the optimal profile comes up implying lower risks for new investments and marketing decisions.

Prioritization of the balancing property and full estimability in mixed-level designs

2008

In a recently published work, a new class of Balanced Asymmetrical Nearly Orthogonal Designs (BANOD2) was proposed, which can simultaneously estimate both first and second order effects of all factors, with a limited run size. The motivation for the new class lies in using the balancing property as a necessary precondition for several practical concerns arising in the experimentation field. A balanced design optimizes the use of experimental resources in technological experiments, may avoid misinterpretations in choice experiments of marketing research, and can relieve the experimenter from the arbitrariness in assigning the levels to factors. Furthermore the balancing property assures the …

Computer experiments combined with physical Experiments: two experiences in product development

2012

Physical experiments in industrial product development are often very expensive but also necessary sometimes even for safety reasons (think about the crash tests in the automotive industry conducted with new and completely equipped vehicles). Therefore there is a pressing need to reduce this cost as much as possible. Computer experiments may be a viable solution provided that their results are reliable as much as the physical ones. In most of the cases, computer experiments are opportunely combined with physical experiments and the recipe of such mix is interesting itself. In this presentation we will show two cases of combination of physical and computer experiments in product development.…

Indagine per la definizione di un modello statistico per lo studio della variabile "contenuto in proteine" nel frumento duro coltivato in Sicilia.

2011

A partire dal 2000 il Consorzio di Ricerca Gian Pietro Ballatore, nell'ambito del "Progetto Qualità e Tracciabilità del Grano Duro in Sicilia", ha attivato, in collaborazione con l'Assessorato delle Risorse Agricole e Alimentari della Regione Siciliana, un sistema di monitoraggio del grano duro, in modo tale da qualificarlo sulla base delle caratteristiche merceologiche, stoccarlo in maniera differenziata e rintracciarlo lungo la filiera. Nell'ambito della suddetta attività per ogni campagna granaria sono stati raccolti dati relativi alle partite di grano conferite presso i centri di stoccaggio che aderivano al progetto. In particolare sono state registrate informazioni sulla qualità merceo…

The Use of Financial and Non-Financial Performance Measures: A Contingency Perspective

2013

Financial and non-financial index and indicators are applied in industry for measure firms’ business and operational performance. Different mix of measures are usually implemented in practice and we argue that, to a certain extent, this variability can be explained according to some contextual factors, as for instance environmental uncertainty, decentralization, type of strategic organizations and managerial practices.We develop hypothesis on the association between the usage of certain performance measures and this factors in a contingency perspective. Exploratory research based on large scale survey on manufacturing firms supports our investigation and test of the research hypothesis. R…

Rethinking the risk matrix

2011

So far risk has been mostly defined as the expected value of a loss, mathematically PL (being P the probability of an adverse event and L the loss incurred as a consequence of the adverse event). The so called risk matrix follows from such definition. This definition of risk is justified in a long term “managerial” perspective, in which it is conceivable to distribute the effects of an adverse event on a large number of subjects or a large number of recurrences. In other words, this definition is mostly justified on frequentist terms. Moreover, according to this definition, in two extreme situations (high-probability/low-consequence and low-probability/high-consequence), the estimated risk…

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 …
