Infermieristica clinica in ortopedia e traumatologia
No full textTesto di Ortopedia e Traumatologia per la Laurea in Infermieristica, in cui si affronta una trattazione completa delle patologie ortopediche e traumatologiche che, incentrata sul paziente piuttosto che sulla patologia, permette di evidenziare chiaramente la funzione dell’assistenza infermieristica e dei principi di riabilitazione. La divisione in capitoli segue, nella prima parte del testo, un’organizzazione secondo i vari distretti corporei, riuscendo così a centrare l’attenzione sul paziente. Nella seconda parte del testo troviamo un’organizzazione più tradizionale per le patologie importanti e per i problemi assistenziali tipici della disciplina, oltre ad un capitolo dedicato alle procedure di uso più frequente. Ogni capitolo della prima parte comprende un paragrafo introduttivo sulle principali patologie del distretto corporeo trattato, per presentare poi le tipologie di pazienti affetti da esse, distinguendo tra patologie traumatiche e non. Si passa poi alle varie fasi dell’assistenza, con riferimento specifico al triage, segni e sintomi, alla diagnostica strumentale, ai trattamenti, incruenti e chirurgici, sempre evidenziando diagnosi infermieristiche e problemi collaborativi. Ogni capitolo è corredato da piani assistenziali standard e da box di approfondimento su argomenti ‘trasversali’ che interessano sia l’ambito ortopedico che quello traumatologico. Numerosi riferimenti incrociati ad altri capitoli, in particolare della parte generale, e ad un glossario, permettono di risolvere rapidamente eventuali dubbi dello studente o a rinfrescare conoscenze di base. Il testo è integrato da un ricco apparato iconografico di tabelle, disegni e fotografie
ESD in Smart Power Processes
No full textElectrostatic Discharge (ESD) is today one of the major concern for Integrated
Circuits (IC) chip quality.
Amerasekera and Duvurry [1] have identified ESD as one of the most common
failure mode in silicon ICs: roughly 10 % of the failing parts is attributed to ESD
event.
Vinson and Liou [2] reported that roughly 20 % of the field return failures may be
attributed to ESD while Wagner et al. [3] identified ESD as being the cause of
greater than 25% of the failures encountered.
Chip redesign and complete new mask set are often required to solve ESD
weakness detected in the product development phase.
Costs associated with these values are huge, but even more difficult to measure are
the intangible costs related to delays and to the loss of customer confidence caused
by failed products.
Advanced process technologies did have a severe impact on ESD robustness: linear
dimensions (channel lengths, gate oxide thickness and junction depth) scaling in
new processes comes together with supply voltage reduction but “unfortunately”
people do not scale accordingly!
For this reason the ESD level requested is not reduced in new technologies and
many new applications, made possible by advanced IC processes, require even
increased ESD performances.
Furthermore advanced technologies allow designers to realize very complex
system on chip (SOC) with very large pin counts. The bonding pad pitch has to
scale properly and the total area available for ESD protection circuit is going to
become smaller and smaller
Optimization of ESD protection structures suitable for BCD6 smart power technology
No full textIn this work we present results concerning the optimization of BCD6 ESD protection structures based on the lateral
DMOS transistor to be used in ESD protection structures adopting the “Big-Clamp” approach. The influence of
common lines parasitic resistance on ESD robustness has been characterized, both by means of TLP measurements
and HBM testing. Threshold voltage shift in NMOS input buffer transistor, following HBM test, has been detected,
suggesting a new failure criteria that should be taken into account for these protection structures. Simple gate-coupled
LDMOS devices with different N-well doping has also been investigated with the aim to identify the effect of the
well doping on the ESD robustness
ESD protection structures for BCD5 smart power technologies
No full textIn this work we present new ESD protections structures, compatible with the in BCD5 smart power technology,
based on an optimization of the “Big-Clamp” approach. By adopting dedicated Vdd and Vss ESD rails and by
replacing the standard diodes with two BJTs, adequately connected to the Vdd and Vss ESD rails, we have obtained
ESD robustness in excess of 8KV HBM for 5V supply voltage structures. By adopting a suitable “Darlington”-
LDMOS we have obtained 7 kV and 4 kV HBM threshold for ESD protection structures suitable for 20 V and 40
V supply voltages respectively
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
Letter from unknown writer to Jesse L. Boyce

Dispelling the Myths Behind First-author Citation Counts
No full textWe 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
