Comparison of different serviceability assessment measures for different events held in the G. Meazza Stadium in Milano
No full textStadia structures, like the G. Meazza in Milano, nowadays host many events that they were not originally designed for. Apart from the traditional football matches many live rock concerts and other public happenings are hosted. In this paper a comparison is made in order to classify the different kind of events in terms of vibration serviceability assessment measurements. The reached vibration levels must be evaluated against the serviceability levels given in existing guidance in order to prevent dangerous situations, such as panic or other uncontrollable phenomena in the crowd. Standards exist to evaluate vibration levels, among them the most widely used are ISO2631-1, ISO2631-2 and BS6841, which differ in the frequency weighting used and in the quantities used to identify the vibration, even though the starting point is the same measured acceleration time histories. More than a comparison of the two standards, already discussed in other papers, this paper investigates the level reached during different events and the influence of all choices left free to the technician performing measurements. Standards are applied to a set of vibration measurements taken on different events on different parts of the G. Meazza stadium. Results are then compared to the reference values suggested in the standards and to the limits found in literature. The effect of the dynamic response of the different sub-structures of the stadium on the reached vibration levels is analyzed and a set of results are given in order to asses the validity of limits given both in the standards and in literature. © 2009 Society for Experimental Mechanics Inc
Il ruolo del suino quale serbatoio e vettore di agenti di zoonosi: valutazione del rischio e proposte per nuove strategie di controllo
No full textSono stati presentati i principali risultati del programma di ricerca finalizzata commissionata dal Ministero della Salute nel 2003.
Gli obiettivi del convegna sono stati: fornire un aggiornamento sulle nuove acquisizioni in tema di eziopatogenesi ed epidemiologia di agenti patogeni batterici e virali classici, emergenti e riemergenti nell’allevamento suino. Facilitare contatti e scambi di informazioni e metodologie tra gli operatori impegnati nel settore.
Sono stati trattati i seguenti argomenti scientifici:
- La salmonellosi suina in Italia in vista dell’applicazione della direttiva zoonosi
- Dinamica della diffusione delle salmonelle in un allevamento suino
- Valutazione igienico sanitaria del processo di macellazione dei suini ad uso familiare
- Presenza di agenti di zoonosi in suini selvatici
- Cloni multiresistenti di emergenti in Italia
- Salmonella in prodotti a base di carne: confronto tra ceppi isolati lungo la filiera suina
- Il ruolo del sistema immunitario del suino nel controllo della salmonellosi
- Biodiversità del TLR 4 nelle popolazioni suine

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
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
