A statistical model for magnitudes and angles of wavelet frame coefficients and its application to texture retrieval
2014
Abstract This paper presents a texture descriptor based on wavelet frame transforms. At each position in the image, and for each resolution level, we consider both vertical and horizontal wavelet detail coefficients as the components of a bivariate random vector. The magnitudes and angles of these vectors are computed. At each level the empirical histogram of magnitudes is modeled by a Generalized Gamma distribution, and the empirical histogram of angles is modeled by a different version of the von Mises distribution that accounts for histograms with 2 modes. Each texture is characterized by few parameters. A new distance is presented (based on the Kullback–Leibler divergence) that allows g…
Influence of online shopping information dependency and innovativeness on internet shopping adoption
2008
PurposeThe paper's purpose is to analyse the influence of online shopping information dependency and innovativeness on the acceptance of internet shopping.Design/methodology/approachThe impact of online shopping information dependency, domain‐specific innovativeness and technology acceptance model (TAM) variables on future shopping intention has been tested through structural equation modelling techniques. The sample consisted of 465 Spanish consumers who had never purchased online.FindingsData analysis shows that consumer innovativeness and online shopping information dependency have a direct and positive influence on future online shopping intention and that the basic TAM hypotheses are f…
Key drivers of consumer loyalty to Facebook fan pages
2014
Purpose – With the rapid expansion of social networking sites, researchers and practitioners are challenged to understand drivers of customer loyalty in fan pages. The purpose of this paper is to identify the main drivers of Facebook fan page loyalty in order to promote the creation of affective links and long-term relationships with users. Design/methodology/approach – The impact of trust, fan page content dependency, attitude and consumer beliefs on loyalty to fan pages was tested through structural equation modelling techniques. The sample consisted of 691 Spanish Facebook users. Findings – Data analysis shows that attitude appears as a key variable in increasing loyalty to fan pages. T…
The strange case of Pomar family: the dangers of roads
2012
Many studies conducted on risk-related issues use quantitative methods. Questionnaires or formal interviews are applied to subjects to construct some attitude or particular opinion about their sense of security. Since the risk-perception theory has been brought from cognitive psychology, there is a biased assumption to think this issue should use these survey types of techniques. In contrast, this article proposes that risk as social construal should be studied according to qualitative analyses that explore the connection between variables. That women perceive more risks than men can be a of second-order explanation, appropriate for opinion polls or managerial policies, but not scientific a…
The Role of the Integrated Public Transport Network for Reducing the Congestion in the City of Palermo
2019
The railway link of Palermo is part of the Palermo – Trapani railway line and it is located in the urban site of Palermo. Works funded by the European Union have been started in 2008 for developing a metropolitan service through the improvement of the infrastructure and of the transport service characteristics. The aim of the paper is the analysis of the capacity of the railway infrastructure in terms of frequency and integration with the public transport service of Palermo. Using the Origin-Destination matrix of the Urban Transport Plan of Palermo, the competition between the private car mode and the public transport mode has been simulated, taking into account the improving of the railway…
Violence at School: A Sample of Young Muslims and Young Valencians
2014
AbstractViolence at school is considered to be an important issue in Spain, despite the fact that the majority of secondary education students reject it. Over the last decade awareness has been raised with regard to this problem. In this study we aim to analyze the perception of school violence held by two very different groups of secondary education students. A sample of young Muslims (n=88) and young Valencians (n=88) (aged between 12 and 18) has been used, all of whom live in the city of Valencia (Spain) and study in 12 secondary educational centers in the city. We observed significant differences in the perception that young Muslims and Valencians have of this violence. Both groups reje…
Dr. Google, what can you tell me about homeopathy? Comparative study of the top10 websites in the United States, United Kingdom, France, Mexico and S…
2019
Users access to Google to find out about health issues is frequent among citizens. This research analyzes the best results of three generic searches on homeopathy, collected in four waves in five countries: Spain, France, Mexico, the United Kingdom, and the United States. Specifically, the fluctuation of the corpus ranking is studied, and a sample of the ten best-positioned pages in each country is taken to analyze their content (the authorship of the website, the stance of the effectiveness of homeopathy, the presence of controversy and the type of content). The results show that the ranking is stable; that the stance of homeopathy is linked to the state of public opinion in the country; t…
EXPLORATION OF EURASIAN PRISON CHAPLAINS’ PSYCHOLOGICAL WELL-BEING TO RAISE THEIR JOB SATISFACTION
2021
The article aims to attract the attention of policymakers, educators, business-affiliated bodies, and community to the psychological well-being of such prison staff members as chaplains whose job satisfaction will directly influence inmates’ rehabilitation and the health of the society in general. A phenomenological research was carried out in a non-profit organization Good News Jail and Prison Ministry whose mission is to provide spiritually mature, equipped, and motivated chaplains serving in 22 states, one American territory and 25 countries. The research sample was the participants of six Eurasian regions. The data were collected using interviews, diary notes and reports of stakeholder …
Which innovation strategy do internationalised firms follow?: evidence from Spain
2016
This paper compares the innovation strategy of internationalised firms, foreign-owned subsidiaries and domestic exporters, relative to firms that serve the domestic market only. The analysis is performed on a sample of manufacturing Spanish firms over the period 2006-2011. We not only focus on different forms of innovation, distinguishing between imitation and pioneer innovation, but also on the heterogeneity of exporters and foreign-owned firms. We find that foreign-owned firms and domestic exporters (excluding those serving only the EU market) are more likely to introduce market novelties ahead of competitors in low-tech sectors and, to a lesser extent, imitate more than local firms. Howe…
The disenchantment of professionals in a new, implemented model of primary health care in Spain: A structural equations model
1992
Abstract A new model of primary health care has been progressively implemented in Spain. Previous research (Peiro and Gonzalez-Roma 1991) suggested that the implementation of this new model has produced a kind of disenchantment—that is, an experience of negative surprise—among health care professionals involved. In the present paper, a structural equations model about the antecedents and consequences of the experience of surprise is tested in a sample of 432 health care professionals working in 44 Primary Health Care Teams (PHCT). The results obtained showed that the number of uncovered functions in the PHCTs, the discrepancy between actual and desired time allocation, and the assessment of…
