No full textL'hedging nel discorso sociologico italiano e tedesco
No full textThis paper aims to describe hedging strategies in German and Italian sociological texts. The domain of sociology was chosen in consideration of the important role attenuating devices can play in this kind of discourse in order to express subtle nuances of meaning or communicative intention.
A bilingual review, containing articles of German and Italian sociologists together with their respective translations, gave the opportunity to conduct both a constrastive and a translational analysis. As a first step, the use of hedges in the original German and Italian articles was analysed in order to find out possible differences between the two languages and cultures. Indeed, the results confirmed the cultural boundedness described in previous studies on other languages and showed different preferences for particular types of hedges: German authors use attenuating devices mainly for the sake of precision, Italian authors mostly for interpersonal reasons. In the second part of the analysis, attention was focused on the problems that can be posed by the translation of hedges. Firstly, the linguistic devices used for hedging purposes may differ in the two languages, so that translators should not content themselves with “direct” equivalents but rather know what forms are most frequently used in the target language. Secondly, translators should consider whether to adapt the patterns of hedging to the conventions of the target language to achieve an equivalent effect. And lastly, it may difficult to determine the precise meaning attributed by an author to a given hedge: in the most complex cases, therefore, the correct interpretation will be obtained only with his consultation
Factors influencing the diagnostic process of carpal tunnel syndrome
No full textThere are no studies regarding the course leading to carpal tunnel syndrome (CTS) diagnosis and factors influencing the diagnostic process. The study aim is to analyse CTS diagnostic path assessing whether the type of physician (general practitioners or specialist) may influence the manner and timing of diagnosis, and whether CTS severity at diagnosis may be predicted by factors related to Public Health Service and/or to patient. A medical history form was filled in by 375 consecutive patients with idiopathic CTS enrolled at an electromyography service. The patient answered a self-administered questionnaire on symptom severity and the neurophysiologist quantified clinical and electrophysiological CTS severity. The patients going directly to general practitioner were older and more blue collars, had minor education level, more symptom duration, more clinical and electrophysiological severity, more medical examination numbers, more time elapsing between first visit to a doctor and referral for EMG than those going to a specialist. But all variables are interrelated and when multivariate logistic regression analyses were performed, only patient age and some other few independent variables related to patient or health care but not to referring doctor could predict CTS severity at the diagnosis. Typology of the first doctor did not influence diagnostic path. The patients should reduce the time elapsing between CTS symptom onset and consulting doctor thus, permitting early treatments. Some corrective actions on diagnostic path may concern the public health service by reducing waiting lists to perform electrodiagnostic testing and giving greater information to population at risk. © 2012 Springer-Verlag Italia
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
Incidence of ulnar neuropathy at the elbow in the province of Siena (Italy)
No full textBackground: Although ulnar neuropathy at the elbow (UNE) is the second most frequent focal peripheral neuropathy of the upper limb after carpal tunnel syndrome (CTS), no figures on its prevalence or incidence in the general population have been reported. Objective: To determine the incidence of UNE in a general population. Methods: Retrospective study to identify newly diagnosed cases on the basis of clinical symptoms or signs and slowing of motor conduction velocity of the ulnar nerve across the elbow or surgical evidence of nerve compression in the elbow region. Results: In the 5-year period from 1995 to 1999, cases among residents in Siena Province (Italy) were identified from medical records of electromyographic services of Local Health District no. 7 and from hospital medical records coded ICD 354.2, 04.49 and 04.6. Siena province has a population of 251,930. In the 5-year period, 311 cases (112 women and 199 men, mean age 56 years, range 15-86) were identified. The mean annual crude incidence was 24.7 cases per 100,000 person-years, and the standardized incidence was 20.9. The sex-specific incidences were 32.7 for men and 17.2 for women. The mean annual crude and sex-specific incidences remained constant during the study period. The age-specific incidences of whole population and both genders showed an increasing trend with decade of age. The incidence of "possible", "probable" and "definite" UNE cases, classified according to level of motor conduction velocity anomalies and evidence of surgical compression of the ulnar nerve at the elbow, was 4.3, 10.6, and 9.8, respectively. The residents of a health subdistrict where manual work is dominant had a higher male-specific incidence (57.1) than other areas. Conclusions: This is the first published study on the incidence of UNE. The incidence was higher in males than females and about one-thirteenth that reported for CTS in part of the present geographic area. © 2005 Elsevier B.V. All rights reserved
NB-IoT Versus LoRaWAN: An Experimental Evaluation for Industrial Applications
Full text linkLow power and long-range communications are crucial features of the Internet of Things (IoT) paradigm that is becoming essential even for industrial applications. Today, the most promising long-range communication technologies are LoRaWAN and Narrow Band IoT (NB-IoT), which are driving a large IoT ecosystem. In this article, we evaluate the performance of LoRaWAN and NB-IoT with accurate in-field measurements using the same application context for a fair comparison in terms of energy efficiency, lifetime, quality of service, and coverage. The NB-IoT energy transmission is scarcely dependent on the payload length. Thus applications that can tolerate buffering and caching techniques on the node are favored. On the other hand, LoRaWAN consumes 10 × lower energy compared to NB-IoT for occasional and latency-sensitive communications, for which it enables much end-device lifetime. Finally, this paper provides design guidelines for future industrial applications with stringent requirements of long-range and low power wireless connectivity
