Disability and work: fitness for work judgement
No full textThe role of physicians, in particular those dealing with health promotion in the workplace, takes on a specific meaning in relation to the difficulties that disabled people encounter both in order to reach the workplace and to reconcile their working activity with the difficulties that result from their condition. Observing the data concerning employment of disabled persons in Italy, it becomes dramatically evident that among the disabled subjects of working age only 17% are employed.
OBJECTIVE: The objective of the occupational health physician is to recognise the impairment, study the disability and, possibly, eliminate or reduce the handicap. Achieving this target is difficult, and there is often a lack in understanding the discomforts experienced by disabled people in their working activity. Expression of a judgement of work fitness for a specific task is a particularly delicate matter, all the more so if the worker is a disabled person. A judgement of work fitness of a disabled person should include evaluation of the person's ability and an analysis of the working task and the workplace.
CONCLUSIONS: Based on our experience, one can safely say that working inclusion and integration in work is possible, without any decrease in productivity, if an appropriate position is found for disabled workers. The occupational health physician has a primary role in the entire process of inclusion of disabled people at work, since he/she knows the company, the tasks, and the associated risks, and furthermore is able to assess the capabilities and abilities of the worker and can thus identify the most suitable and safe working situation
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

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
Logistica di Approvvigionamento, interna e distributiva
No full textIn linea con le definizioni di supply chain e logistica analizzate nel capitolo II, l’obiettivo di questo capitolo è quello di analizzare la struttura dei tre macro-processi della logistica: la logistica d’approvvigionamento (inbound), logistica interna e logistica distributiva (outbound).
Dopo una breve panoramica su questi tre macro-processi, il capitolo introdurrà un tema fondamentale per la loro pianificazione, coordinamento e controllo: la gestione e la previsione della domanda. Un’efficace attività di previsione e di analisi della domanda permettono una più efficiente funzionamento dei processi logistici aziendali.
Successivamente, saranno analizzati nel dettaglio i processi strategici, di pianificazione ed operativi delle attività concernenti la movimentazione dei beni, le informazioni ed i flussi finanziari dei tre processi logistici.
In particolare, nello studio della logistica d’approvvigionamento (inbound) si illustreranno le attività strategiche e la strutturazione del sistema della logistica inbound, il marketing d’acquisto e la gestione delle relazioni con i fornitori. L’analisi dei processi di logistica interna saranno invece indirizzati allo studio dei processi di pianificazione, gestione e controllo dei flussi fisici ed informativi relativi alla produzione e stoccaggio delle merci. L’esame della logistica distributiva (outbound), infine avrà come oggetto le strategie e la pianificazione della distribuzione, la gestione del trasporto e del post-vendita.
Inoltre, essendo la logistica d’approvvigionamento, interna e distributiva storicamente oggetto degli studi d‘integrazione volti all’ottimizzazione dell’intero processo logistico (Grando, 1996; Pivato et. Al, 2004; Christopher, 2011), questo capitolo si concluderà con l’illustrazione delle maggiori criticità ed opportunità legate all’integrazione dei tre processi logistici.
Infine, nel settimo paragrafo i tre macro-processi saranno analizzati alla luce di differenti settori economici e per ognuno, illustrate le complessità e i fattori chiave di successo
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Airbnb e processi di touristification: un’analisi socio-territoriale a partire dal caso di Bologna
No full textQuesto contributo propone un’analisi della diffusione di Airbnb a Bologna e del suo potenziale impatto sul mercato abitativo residenziale. Particolare importanza riveste l’analisi della struttura interna della piattaforma, dei suoi attori e delle loro proprietà. L’attività di Airbnb emerge attraversata da molteplici tensioni, tanto rispetto alla proprietà degli annunci quanto alla distribuzione dei ricavi, e la piattaforma emerge in ultima istanza come un fattore di divaricazione sociale. Questi elementi favoriscono la comprensione dei suoi effetti socio-territoriali, primo fra tutti l'impatto sul mercato abitativo con l'aumento della tensione abitativa, il potenziale ruolo di vettore di processi di espulsione urbana e touristification nel Centro Storico e di gentrification nella prima periferia. L’influenza del territorio e delle sue specificità in questi processi emerge come centrale
