No full textHealth Care Expenditure and Economic Growth in Southern Italian Regions: an Empirical Analysis
No full textQuesto saggio investiga il nesso tra la spesa sanitaria e il PIL per le regioni del Mezzogiorno d’Italia nel periodo 1980-2009 utilizzando un approccio di serie storiche. Lo studio parte da un’introduzione e una rassegna della letteratura economica sul tema, prima di discutere i dati utilizzati e di introdurre alcune tecniche econometriche. I test di stazionarietà e radici unitarie rivelano che le serie della spesa sanitaria e del PIL sono entrambe I(1), per tutte le regioni. Inoltre, troviamo ovunque una relazione di cointegrazione tra le variabili. La dinamica di breve periodo mostra che il flusso di causalità è di tipo bidirezionale in sei casi su otto, e anche nel lungo periodo sussiste una relazione causale bidirezionale (o “effetto di feedback”) tra le due serie. Di conseguenza, concludiamo che la spesa sanitaria sia un fattore limitante per la crescita economica delle regioni dell’Italia Meridionale
The Determinants of Health Expenditure in Italian Regions
No full textThe health care expenditure in Italian regions is examined, applying the model selection procedure and panel methodologies to identify the determinants of health expenditure at the state level. After a brief introduction and a survey of the economic literature on this issue, we discuss the data and brief-ly introduce the methodologies. Empirical results suggest that the real Gross State Product, the unem-ployment rate, the number of beds in community hospitals, the urbanization degree and the percentage of the population with at least the junior high school degree had a direct impact on the real health care outlay. Furthermore, the income elasticity is below the unity (0.83-0.88 according to the static panel estimates, 0.43-0.48 for the dynamic methods), implying that health expenditure is a ne-cessity rather than a luxury good at the state level
A new method for the design of knowledge-based engineering systems for manufacturing
No full textKnowledge-based engineering systems for manufacturing are used to digitalise the process know-how and reuse this knowledge within the design and production phases. Their adoption allows the establishment of beneficial interactions between human experts and intelligent systems. An initial implementation of these systems can be confusing and infeasible, especially for small and medium enterprises which have not had sufficient previous experiences in applying these approaches. The main reason for this is the wide range of different scenarios that occur in real industrial cases. Existing methods that were proposed for the design of knowledge-based engineering systems fail to fulfil the needs of process engineering because they do not include certain fundamental aspects of the product design and manufacturing. This article presents a new systematic approach to design and develop knowledge-based engineering systems for manufacturing surpassing these limitations. This approach includes graphic representations that depict and organise all the relevant elements of the system. First of all, the method is described detailing the operations which have to be performed to design a new system. Finally, a real case to highlight the association between the preliminary design phase and the features of the implemented knowledge-based engineering systems for manufacturing is presented. The method is demonstrated to be a flexible approach to the systematic implementation of intelligent systems for manufacturing. Being user-friendly, its use will increase the number of potential users in small and medium enterprises
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Lipid supplementation in small ruminant nutrition and dairy products quality: implications for human nutrition
No full textVariations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
