Cerda
No full textLa città di Cerda si colloca a poca distanza dal fiume Imera Settentrionale, lungo la strada che collega la costa tirrenica della Sicilia con l’entroterra. La fondazione si deve al nobile Giuseppe Santostefano e Cerda, che nel 1656 ne avvia la costruzione e dopo tre anni ottiene la licentia populandi dal re Filippo IV
The prolegomena of La Cerda's commentary on Virgil : a commented edition from the Cologne 1642 imprint, with English translation and explanatory notes
No full textThis thesis presents a new Latin text of the Prolegomena and accompanying prefatory material of the Cologne 1642 edition of the Virgil commentary by the Spanish Jesuit scholar Juan Luis De La Cerda. It provides an original English translation of this material along with explanatory notes which focus upon the social, educational, intellectual and political influences that informed La Cerda's work. The notes also take account of some of the
rhetorical and stylistic aspects of La Cerda's work. An introduction situates the work in its cultural and intellectual context and provides a clear overview of the structure and composition of the Prolegomena

Changes in cathepsin gene expression and relative enzymatic activity during gilthead sea bream oogenesis
No full textThe aim of this study was to provide evidence on the modulation of lysosomal enzymes in terms of both gene expression and enzymatic activity during follicle maturation. For this purpose three lysosomal enzymes, cathepsins B, D, and L, were studied in relation to yolk formation and degradation, during the main phases of ovarian follicle growth in the pelagophil species, the sea bream Sparus aurata. Specific attention was focused on the gene expression quantification method, on the assay of enzymatic activities, and on the relationship between the proteolytic cleavage of yolk proteins (YPs), cathepsin gene expression and cathepsin activities. For the gene expression study, the cathepsins B-like and L-like mRNAs were isolated and partially or fully characterized, respectively; the sequences were used as design specific primers for the quantification of cathepsin gene expression by real-time PCR, in follicles at different stages of maturation. The enzymatic assays for cathepsins B, D, and L were optimized in terms of specificity, sensitivity and reliability, using specific substrates and inhibitors. In ovulated eggs, the lipovitellin I (LV I) was degraded and the changes in electrophoretic pattern were preceded by an increase in the activity of a cysteine proteinase, cathepsin L, and its mRNA. Cathepsin B did not appear to be involved in YP changes during the final maturation stage
Anomaly detection for fault detection in wireless community networks using machine learning
No full textMachine learning has received increasing attention in computer science in recent years and many types of methods have been proposed. In computer networks, little attention has been paid to the use of ML for fault detection, the main reason being the lack of datasets. This is motivated by the reluctance of network operators to share data about their infrastructure and network failures. In this paper, we attempt to fill this gap using anomaly detection techniques to discern hardware failure events in wireless community networks. For this purpose we use 4 unsupervised machine learning, ML, approaches based on different principles. We have built a dataset from a production wireless community network, gathering traffic and non-traffic features, e.g. CPU and memory. For the numerical analysis we investigated the ability of the different ML approaches to detect an unprovoked gateway failure that occurred during data collection. Our numerical results show that all the tested approaches improve to detect the gateway failure when non-traffic features are also considered. We see that, when properly tuned, all ML methods are effective to detect the failure. Nonetheless, using decision boundaries and other analysis techniques we observe significant different behavior among the ML methods
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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

Square Dancing with the Stars to Enhance Dynamic Hirschman Linkages?
No full textIn this Presidential Address, the author takes the reader on a reconnaissance of his life and time as a regional scientist. He points out scenery he found scintillating along the way, hoping that some may pick up the banner and chew on a few of the ideas for a while. He suggests a revisit to Albert O. Hirschman’s notion of key sectors and more empirical analysis related to Marcus Berliant’s and Masahisa Fujita’s notion of knowledge creation and transfer.Presidential Address, San Antonio, Texas, March 29, 2014 (53rd Meetings of the Southern Regional Science Association
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe 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

Durée : 32 : 48 minutesDepuis la révolte sociale de 2019, le Chili cherche à élaborer une nouvelle Constitution. L’objectif est de remplacer la Constitution léguée par la dictature d’Augusto Pinochet, mais aussi de consacrer de nouveaux droits et libertés, notamment sociaux. Un premier texte, particulièrement progressiste et protecteur des minorités, a été écrit en 2022, mais il a finalement été rejeté par le peuple par référendum. Un second est en cours de rédaction depuis 2023, et il se présente au contraire comme un texte particulièrement conservateur. Étudier le cas chilien permettra de mieux comprendre les difficultés que l’on rencontre au moment de garantir dans une Constitution de nouveaux droits, et en particulier les droits des groupes traditionnellement opprimés, qu’il s’agisse des femmes ou des communautés autochtones
