Giovani alla ricerca di senso (del lavoro): le aspirazioni della generazione Z
No full textUn’indagine esplora ciò che i giovani della Generazione Z si aspettano dal lavoro e dalla carriera. Attraverso un questionario somministrato agli studenti di circa 30 università italiane, lo studio ha approfondito le caratteristiche del lavoro desiderato e il tipo di carriera a cui ambiscono, le principali politiche e pratiche di organizzazione e gestione del personale che apprezzano, il tipo di organizzazione ricercata e le qualità della città ideale in cui intendono costruire la propria carriera. I risultati della ricerca restituiscono una fotografia non scontata su ciò che questa generazione si aspetta dal futuro lavorativo ed evidenziano alcune differenze significative tra i giovani, fornendo così spunti preziosi per guidare politiche aziendali e pratiche operative
Che lavoro desidera la Generazione Z? Un’indagine sulle aspettative lavorative degli studenti italiani.

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
Variations 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
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

No full textSommario
Il reparto assemblaggio motori di Piaggio & C. S.p.A, nella fase di industrializzazione del nuovo motore M648, ha proposto l'introduzione di un nuovo metodo per l'analisi delle fasi di montaggio e per lo studio delle attrezzature e delle macchine necessarie.
Tale esigenza è nata in quanto la progettazione delle attrezzature, dei macchinari e della stessa linea di montaggio viene affidata a fornitori esterni.
Si presentano, dunque, problematiche legate all'aspettativa da parte dell'azienda committente, alla riservatezza delle informazioni che devono essere fornite insieme all'ordine, e ad eventuali ritardi in cui si può incorrere per incomprensioni fra le parti.
L'obiettivo del presente lavoro è quello di migliorare il ciclo di montaggio, generando un'immagine 3D per ogni fase di lavoro, mediante l'utilizzo di un software di modellazione CAD.
In tal modo, puntando sulla chiarezza della documentazione da inviare nella fase di richiesta delle attrezzature, ci si attende di ridurre drasticamente i tempi d'attesa per le forniture.
Abstract
The engine assembly department of Piaggio & C. S.p.A. in the industrialization phase of the new engine M648, propose the introduction of a new method for the analysis of assembly phases and for the studies of the necessary machines and equipments.
This need arose because the design of equipments, machinery and the same assembly line was entrusted to outside suppliers.
We have, therefore, issues related to the expectations of the buyer, confidentiality of information that they provided with the order and any delays which can occur for misunderstandings between the parties.
The purpose of this work is to improve the assembly cycle, generating a 3D image for each phase of work, by using the modelling software CAD.
Thus, focusing on clarity of documentations to be sent during application equipment, is expected to reduce drastically the time of supplies
