Pārrobežu tiešsaistes iepirkšanās un patērētāju uzvedības analīze Ķīnā
2019
Ķīnas patērētāju ikdienā un Ķīnas starptautiskajā tirdzniecībā ir nozīmīgi pieaugusi pārrobežu e-komercijas loma. Ar starptautisko preču mazumtirdzniecības pieaugošu nozīmi ir jāpievērš lielāka uzmanība patērētāju uzvedības tiešsaistē izpētei, bet tikai daži pētījumi koncentrējas konkrētai pārrobežu tiešsaistes iepirkšanās jomai. Šis pētījums veicina patērētāju pārrobežu tiešsaistes iepirkšanās attieksmes un rīcības izpēti. Tā mērķis ir izpētīt faktorus, kas ietekmē nodomu piedalīties pārrobežu iepirkumos tiešsaistē un veikt esošo Ķīnas tiešsaistes patērētāju attieksmes, kas balstīta uz identificētajiem faktoriem, mērījumus. Ierosinātais attieksmes modelis ir balstīts uz tiešsaistes un pārr…
Comparación del valor democrático de las discusiones de Facebook entre perfiles de candidatos políticos españoles a las elecciones generales de 2011
2017
This article examines the democratic value of user-generated comments on the Facebook profiles of three Spanish candidates during the Spanish General Election campaign of 2011 through a content analysis that operationalizes deliberative democracy. The findings show that these online spaces do not meet deliberative standards, but that they still serve democratic functions, such as citizen self-expression, democratic socialization and reinforcement of social cohesion among party activists and sympathizers. Moreover, results indicate that democratic value might vary depending on the size of the party where talk takes place. Political conversation on the walls of hegemonic candidates who belong…
Idiopathic Seidlmayer's Purpura: A Case Report
2014
Acute hemorrhagic edema of infancy (AHEI) was considered a rare form of Henoch-Schönlein purpura; however, it is now regarded as an independent disease typically involving patients aged 4-24 months. The authors describe the clinical case of a toddler aged 8 months, with skin erythematous pomphoid<b> </b>lesions, treated at home with topical steroids without benefits. The appearance of new lesions and the worsening of the previous skin signs induced the parents to drive the child to the hospital. The medical history revealed the administration of a vaccine dose 2 months before.
Discovering Homophily in Online Social Networks
2018
During the last ten years, Online Social Networks (OSNs) have increased their popularity by becoming part of the real life of users. Despite their tremendous widespread, OSNs have introduced several privacy issues as a consequence of the nature of the information involved in these services. Indeed, the huge amount of private information produced by users of current OSNs expose the users to a number of risks. The analysis of the users’ similarity in OSNs is attracting the attention of researchers because of its implications on privacy and social marketing. In particular, the homophily between users could be used to reveal important characteristics that users would like to keep hidden, hence …
Pattern Dystrophy of the Macula in a Case of Steinert Disease
2013
<b><i>Introduction:</i></b> Myotonic dystrophies are typically associated with ocular complications like ptosis, weakness of the ocular muscle and cataracts, but also with less recognized retinal changes. <b><i>Case Report:</i></b> A 41-year-old female with type 1 myotonic dystrophy complained of progressive vision loss. Slit lamp examination revealed the presence of typical bilateral polychromatic cataract with posterior subcapsular component. Dilated fundus examination was remarkable for bilateral macular depigmented changes. Multimodal imaging analysis of the macula suggested the presence of a butterfly-shaped pattern dystrophy. <b>&l…
FLIGHT CONTROL RESEARCH LABORATORY UNMANNED AERIAL SYSTEM WIND SHEAR ON-LINE IDENTIFICATION
2013
An algorithm to perform the on line identification of the wind shear components suitable for the UAS characteristics has been implemented. The mathematical model of aircraft and wind shear in the augmented state space has been built without any restrictive assumption on the dynamic of wind shear. Because of the strong velocity variations typical of wind shear induce severe accelerations on the aircraft the wind shear effects have been modeled as external forces and moments applied on the aircraft. The identification problem addressed in this work has been solved by using the Filter error method approach. An Extended Kalman Filter has been developed to propagate state. It has been tuned by u…
Donne&Diritti sul Web. Guida alle risorse online. Dossier tematico
2012
Il dossier, diviso in categorie tese a riflettere la sistematizzazione tradizionale delle risorse online utili alla ricerca storica tout court (banche dati bibliografiche, bibliografie e cataloghi online, fonti primarie, periodici elettronici, corsi e materiali per l’insegnamento, portali, ricerche e progetti) offre una panoramica delle risorse online (italiane e straniere) nell'ambito della storia della condizione giuridica delle donne. Progettato per aiutare nella ricerca e nel reperimento di informazioni e fonti, propone un percorso ragionato che consente l’accesso ad alcune tra le interessanti risorse relative allo studio, la conservazione, la diffusione di documentazione e altri materi…
A Framework for Opening Data and Creating Advanced Services in the Health and Social Fields
2016
Open data is publicly available data that can be universally and readily accessed, used, and redistributed. Open data holds particular potential in the health and social sectors but, presently, health and social data are often published in a ‘closed’ format.There are different tools that allow to ‘open’ data, clean, structure and process them in order to elaborate them and build advanced services but, unfortunately, there is no single tool that can be used to perform all different tasks. We believe that the availability of Open Data in the health and social fields should be greatly increased and a way for creating new health and social services should be provided. In this paper, we present …
El uso político de Twitter en la campaña de las Elecciones Locales de 2015 en la ciudad de València
2020
La investigación analiza el uso político de Twitter en la campaña de las Elecciones Locales de 2015 en la ciudad de Valencia. El trabajo realiza una comparación de la presencia y de la actividad en dicha red de microblogging de las cinco formaciones políticas que obtuvieron representación en la corporación municipal (el Partido Popular, Compromís, Ciudadanos, PSPV-PSOE y València en Comú) y sus respectivos candidatos (Rita Barberá, Joan Ribó, Fernando Giner, Joan Calabuig y Jordi Peris). Lo hace mediante una metodología de análisis cuantitativo ya consolidada y que resulta especialmente conveniente para documentar la progresiva implantación de las aportaciones potenciales de la comunicación…
Semantic User Profiling for Digital Advertising
2015
International audience; With the emergence of real-time distribution of online advertising space (“real-time bidding”), user profiling from web navigation traces becomes crucial. Indeed, it allows online advertisers to target customers without interfering with their activities. Current techniques apply traditional methods as statistics and machine learning, but suffer from their limitations. As an answer, the proposed approach aims to develop and evaluate a semantic-based user profiling system for digital advertising.
