Sentiment Analysis of Twitter in Tourism Destinations

2020

[EN] Given the importance of electronic word of mouth (eWOM), this paper analyses the content of messages generated by users related to a tourist destination and shared through Twitter. We propose three research questions regarding eWOM behaviour in Twitter focused on the expertise of the reviewer, sentiment analysis of a tweet and its content.In order to address those research questions we carry out text mining analysis by retrieving existing information on Twitter (over 1500 tweets) regarding to Venice as a tourist destination.

Licofelone, a novel 5-LOX/COX-inhibitor, attenuates leukocyte rolling and adhesion on endothelium under flow

2005

The main mechanism of action of non-steroidal anti-inflammatory drugs (NSAIDs) is the inhibition of cycloxygenases COX-1 and COX-2. During recent years, combined 5-LOX/COX-inhibition, interfering with the biosynthesis of both prostaglandins and leukotrienes (LTs), has emerged as a possibility to avoid side effects related to COX-inhibition. The aim of the present study was to investigate if there is a contribution of mechanisms other than the reduction of inflammatory prostaglandins and leukotrienes to the anti-inflammatory effect of the LOX/COX inhibitor licofelone. In a flow chamber assay, licofelone (10-30 microM) dose-dependently decreased both the rolling and adhesion of leukocytes on …

Una revisión a la planificación de los recursos: sobre los enfoques de evaluación y los modelos de adaptación al uso turístico

2018

Mucho se ha hablado de la planificación del turismo. Solo cabe echar una mirada a la literatura académica para encontrar decenas de propuestas metodológicas que, desde inicios de los años 50 del siglo pasado, vienen exponiéndose. A pesar de esta vorágine creativa, todas ellas acaban, finalmente, enmarcándose en uno de los cinco enfoques identificados por Hall (2008). Sin embargo, al realizar ese mismo ejercicio para el caso de los recursos, considerados la base sobre la que asentar cualquier proceso de desarrollo turístico, los resultados sobre cómo planificarlos difieren considerablemente. Esta investigación, de carácter teórico, realiza una revisión bibliográfica de los trabajos académico…

Morally Successful Collaboration between Academia and Industry — A Case of a Project Course

2006

Academia-industry collaboration is common in the IT-field, and it includes training programs, research centre activities, and industry advisory boards (Watson and Huber 2000). For the industry, co-operation provides possibilities to acquire human resources and, for the academia, co-operation ensures that research and teaching activities are relevant. Regardless of its popularity little is known about moral issues relating to this phenomenon. This study intends to fill the gap in knowledge by determining the nature of moral conflicts perceived by clients, students, and instructors of a collaborative project course, and by formulating a framework to successfully getting grips with these confl…

An FPGA-Based Software Defined Radio Platform for the 2.4GHz ISM Band

2006

A prototype of a Software Defined Radio (SDR) platform has been successfully designed and tested implementing a reconfigurable IEEE 802.11 and ZigBee receiver. The system exploits the reconfiguration capability of an FPGA for implementing a number of receiver configurations that share the same RF front-end. Configurations can be switched at run time, or can share the available logic and radio resource.

A description model for regeneration through urban tourism in rural towns with underused historic real estate

2016

Il presente contributo propone un modello di descrizione (description model) che trova applicazione in una situazione reale di aiuto alla decisione posto dall'urbanista per lo sviluppo turistico delle città rurali nelle zone dell'entroterra siciliano. Il problema decisionale riguarda la città di Cianciana (AG), che negli ultimi anni si è resa protagonista di un particolare fenomeno di turismo internazionale. In particolare, proponiamo un quadro valutativo multicriteriale per la riqualificazione fisica ed economica del centro storico della città attraverso lo sviluppo del turismo. Il modello presentato, relativo a un problema decisionale di tipo descrittivo, è orientato a supportare i deciso…

Aerobic granular sludge treating anaerobically pretreated brewery wastewater at different loading rates.

2020

Abstract In this study, three different aerobic granular sludge (AGS) reactors fed with anaerobically pre-treated brewery wastewater were studied. The AGS reactors were operated under different conditions including organic loading rates (OLR) between 0.8 and 4.1 kg COD m−3 d−1, C:N:P ratios (100:10:1 and 100:6:1) and food to microorganism ratios (F/M) between 0.8 ± 0.6 and 1.2 ± 0.5 and 0.9 ± 0.3 kg-TCOD kg-VSS−1d−1. Stable granulation was achieved within two weeks and the size of the granules increased according to the OLR applied. The results indicated that low C:N:P and F/M ratios were favorable to achieve stable aerobic granules in the long term. The carbon removal rate was load-indepen…

Stability criteria, atomization and non-thermal processes in liquids

2008

Analyzing the first equation in the BBGKY chain of equations for an equilibrium liquid-gas system, we derived the analytical expression for the atom work function from liquid into gas. The coupling between the atom work function from liquid into vacuum and the stability criterion of liquid in limiting points of the first type was shown (using I.Z.. Fisher classification). As it turned out, Fisher's criterion corresponds to the condition of atomization. We have expressed the state equation in terms of the atom work function from liquid into vacuum and performed calculations of the limiting line of stability composed of limiting points of the first type for argon. Our model discovers an inter…

Scad-elastic net and the estimation of individual tourism expenditure determinants

2014

This paper introduces the use of scad-elastic net in the assessment of the determinants of individual tourist spending. This technique approaches two main estimation-related issues of primary importance. So far studies of tourism literature have made a wide use of classic regressions, whose results might be affected by multicollinearity. In addition, because of the absence of robust economic theory on tourism behavior, regressor selection is often left to researcher's choice when not driven by non-optimal automatic criteria. Scad-elastic net is an OLS model that accounts for both these problems by including two types of parameters constraints, namely the smoothly clipped absolute deviation …
