Henrik Wergeland's Bouquet: Fredrika Bremer, Sentimentality and Nationalism inJan van Huysum's Flower Piece

2015

Henrik Wergeland's poem Jan van Huysums Blomsterstykke (1840) is often characterized as a key work of Norwegian and Nordic romanticism. Where previous criticism has primarily focused on the poem's ekphrastic dimension, this reading will draw attention to how it employs many forms and genres, at the same time examining neglected thematic strands in the poem. A key lead to the poem's generic placement is provided by its oft-overlooked front-page, paratextual dedication to the Swedish novelist Fredrika Bremer. It will be argued that works by Bremer, such as Hemmet, not only provide some precedent for the ekphrastic dimension of Wergeland's poem, but more importantly reveal the latter text's un…

Distributed Real-Time Sentiment Analysis for Big Data Social Streams

2014

Big data trend has enforced the data-centric systems to have continuous fast data streams. In recent years, real-time analytics on stream data has formed into a new research field, which aims to answer queries about "what-is-happening-now" with a negligible delay. The real challenge with real-time stream data processing is that it is impossible to store instances of data, and therefore online analytical algorithms are utilized. To perform real-time analytics, pre-processing of data should be performed in a way that only a short summary of stream is stored in main memory. In addition, due to high speed of arrival, average processing time for each instance of data should be in such a way that…

Jean-Baptiste Du Bos e Jean-Jacques Rousseau. Un’estetica del sentimento.

2014

La ricerca avviata sul rapporto tra l’Abbé Du Bos e Jean–Jacques Rousseau è rivolta a rintracciare presenze dubosiane (esplicite o implicite) all’interno degli scritti rousseauiani e, secondariamente, a indicare come alcuni temi affrontati da Du Bos nelle sue Réflexions critiques sur la poésie et la peinture (1719) trovino spazio di adesione, problematizzazione, approfondimento, revisione o negazione in Rousseau. I due versanti del lavoro di ricerca sono quindi strettamente legati tra di loro: il secondo nasce dal primo per ‘gemmazione’, ed è decisivo per tentare di individuare il profilo del pensiero estetico di Rousseau. Un primo passo nella ricerca (svolto nei primi due capitoli della te…

Guided Tour Influence on Cruise Tourist Experience in a Port of Call: An eWOM and Questionnaire-Based Approach

2016

The study aims at exploring the importance of guided tours in cruise tourists experience while visiting a port of call and analyzing qualitative (electronic word of mouth from Tripadvisor) and quantitative (personal interviews with tourists) data. The results obtained from the electronic word of mouth analysis suggest that taking a guided tour is a highly satisfactory and sentimentally positive experience for the cruise tourist. Moreover, the empirical findings revealed that taking a guided tour has a moderating effect on (1) the interaction between destination image–satisfaction, (2) the satisfaction–loyalty causal relationship and (3) the destination image formation process regarding the …

A Data-Driven Approach to Dynamically Learn Focused Lexicons for Recognizing Emotions in Social Network Streams

2016

Opinion Mining aims at identifying and classifying subjective information in a collection of documents. A variety of approach exists in literature, ranging from Supervised Learning to Unsupervised Learning. Currently, one of the biggest opinion resource of opinionated texts existing on the Web is represented by Social Networks. Networks are not only a vast collection of documents but they also represent a dynamic evolving resource as the users keep posting their own opinions. We based our work relying on this idea of dynamicity, building an evolving model that updates itself in real time as users submit their posts. This is done through a set of supervised techniques based on a Lexi- con of…

How News Affect the Trading Behavior of Different Categories of Investors in a Financial Market

2012

We investigate the trading behavior of a large set of single investors trading the highly liquid Nokia stock over the period 2003-2008 with the aim of determining the relative role of endogenous and exogenous factors that may affect their behavior. As endogenous factors we consider returns and volatility, whereas the exogenous factors we use are the total daily number of news and a semantic variable based on a sentiment analysis of news. Linear regression and partial correlation analysis of data show that different categories of investors are differently correlated to these factors. Governmental and non profit organizations are weakly sensitive to news and returns or volatility, and, typica…

Equity Issues in the Spanish Stock Market: Windows of Opportunity, Earnings Management or Market Timing?

2005

We investigate whether the market sentiment and/or the specific operating performance of firms that conducted an equity issue on the Spanish stock market during the period 1993-2000 are related to the long-run stock-return underperformance in the year following the issue of small and medium firms. Our results reveal that equity issues were conducted by large firms just when the market showed optimistic expectations towards large firms in general. This overoptimism towards large issue firms was related to the 1990s technology boom in the case of initial public offerings (IPO), but we detect earnings management by large firms that conducted a seasoned equity offering (SEO). In this context, s…

This research work adresses the prediction of success after a training scheme (success in university examination, integration of job seekers after a training session) on the basis of 1/ subjective indicators at the end of training: satisfaction or subjective learning and 2/ individuals' variables (self-efficacy, locus of control, self-esteem, optimism and core self-evaluation). Our results show that, compared to training evaluation models, subjective indicators at the end of training do not appear to be good predictors of success. In addition, if individuals' variables are sometimes predictable of success, this seems to be related to the mere fact that they represent high values in students…
