ORGANIZATIONAL CHANGE AND PATTERN OF NETWORK CHURN
No full textLa tesi ha l’obiettivo di analizzare il cambiamento organizzativo in una prospettiva di social network analysis, sfruttando dati longitudinali raccolti a seguito della modifica della struttura organizzativa in un Policlinico Universitario italiano. Il manoscritto è organizzativo in tre paper. Il primo paper si focalizza sul tema del rapporto tra network formali e network informali, analizzando come la modifica del primo comporti una corrispondente variazione nel secondo. Il paper dimostra come, in assenza di strutture organizzative ben formalizzate, gli individui tendono ad allacciare nuovi legami con colleghi che appartengono alla stessa specializzazione.
Il secondo paper, invece, attingendo prettamente alla letteratura di comportamento organizzativo, analizza il tema della dinamicità del network, fornendo evidenze in relazione alla stabilità del network stesso a seguito del cambiamento. Particolare attenzione, è inoltre, dedicata alle dinamiche intra – team e al ruolo di quest’ultime nell’accettazione o meno del cambiamento.
Infine, il terzo paper sviluppa il tema della network density e di come quest’ultima possa essere correlato al cambiamento organizzativo, in termini di reazione al cambiamento. Inoltre, si dimostra come la formalizzazione abbia un impatto positivo sulla densità del network, specie in contesti organizzativi caratterizzati da una bassa gerarchia e coordinamento orizzontale.This thesis aims to analyze organizational change in a social network analysis perspective, exploiting longitudinal data collected after a modification of the organizational structure in an Italian Teaching Hospital The manuscript is organized into three papers. The first paper focuses on the theme of the relationship between formal networks and informal networks, analyzing how the modification of the first involves a corresponding variation in the second. The paper demonstrates how, in the absence of formalized organizational structures, individuals tend to establish new ties with colleagues who belong to the same specialization.
The second paper, drawing purely from the organizational behavior literature, analyzes the issue of the network dynamics , providing evidence and antecedents for network stability in response to organizational change. Particular attention is also given to the intra - team dynamics and the impact of individual perception of collective properties in driving employees in accepting or not the organizational change.
Finally, the third paper develops the theme of network density and how the latter can be related to organizational change, in terms of reaction to change. Furthermore, it is shown how formalization has a positive impact on network density, especially in organizational contexts characterized by a low hierarchy and horizontal coordination
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
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
L'importanza dell'organizzazione in oncologia: collaborazione e coordinamento. Evidenze da una ricerca intervento sul tumore del polmone
No full textInter and intra organizational coordination is a key topic for organizational
scholars, especially in the healthcare sector. Despite a wide literature on multidisciplinary team management of cancer patients, existing evidence have not fully analysed which structures, actors, tools and social dynamics are associated with an effective clinical team. This study, through the action research, analyses the current ways of management of Lung Cancer Patients and proposes an optimal model consisting in some organizational guidelines to be applied to ensure an effective management. Our analysis identifies and detail three pillars characterizing the optimal model:
1) the characteristics of the disease management team, 2) the organizational infrastructure ensuring the adoption of Clinical pathways, 3) an integrated system of indicators
Hospital reorganization and its effects on physicians’ network churn: The role of past ties
No full textHospital reorganizations are difficult and often fail to produce their intended benefits. Prior research has investigated how and under which contingencies changes in organizational structure affect the modification of clinician behaviors, yet we know little about how organizational redesign interventions affect physicians' collaborative networks. This paper explores how hospital reorganizations affect physicians' network churn. We developed hypotheses on the relationship between structural characteristics of networks before reorganization and the formation of cross-unit network ties after reorganization. We tested our hypotheses on a sample of 175 physicians in a large teaching hospital. The hospital had recently adopted a new organizational model aimed at enhancing a process-based approach to care delivery. Our findings revealed that the physicians' propensity to form cross-unit ties after the change was related to the structure of their collaborative networks before the change. In particular, the formation of cross-unit relations was negatively related to the size of advice networks before the reorganization. Furthermore, we found that the diversity of network ties along with the presence of structural holes in the physicians’ networks before the change moderated this relationship. We discussed the theoretical and practical implications of our findings. In particular, our results may inform organizational redesign interventions within hospitals
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
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
