MDCT and virtual angioscopy in spontaneous aortocaval fistula

2007

Aortocaval fistula is a rare, less than 1%, but life threatening complication, of abdominal aortic aneurysm. Mortality is high but prompt recognition of the fistula can reduce mortality rate. The multidetector row CT (MDCT) findings in a 69-year-old patient with a complex medical history characterized by previous episodes of myocardial ischemia, is reported. MDCT shows an early homogeneous enhancement of the inferior vena cava, slightly dilated at the liver level and markedly narrowed above the renal vein due to aneurysm compression. The patient underwent to emergency laparotomy but died during surgery for cardiac arrest. MDCT allows a prompt recognition of the fistula and different compute…

In vivo versus augmented reality exposure in the treatment of small animal phobia: A randomized controlled trial

2016

Although in vivo exposure is the treatment of choice for specific phobias, some acceptability problems have been associated with it. Virtual Reality exposure has been shown to be as effective as in vivo exposure, and it is widely accepted for the treatment of specific phobias, but only preliminary data are available in the literature about the efficacy of Augmented Reality. The purpose of the present study was to examine the efficacy and acceptance of two treatment conditions for specific phobias in which the exposure component was applied in different ways: In vivo exposure (N = 31) versus an Augmented Reality system (N = 32) in a randomized controlled trial. “One-session treatment” guidel…

Collective Behavior of Price Changes of ERC-20 Tokens

2020

We analyze a network constructed from tokens developed on Ethereum platform. We collect a large data set of ERC-20 token prices; the total market capitalization of the token set is 50.2 billion (109) US dollars. The token set includes 541 tokens; each one of them has a market capitalization of 1 million US dollars or more. We construct and analyze the networks based on cross-correlation of tokens’ returns. We find that the degree distributions of the resulting graphs do not follow the power law degree distribution. We cannot find any hierarchical structures nor groupings of ERC-20 tokens in our analysis. peerReviewed

Virtual and augmented reality: Advancing research in consumer marketing

2020

Abstract Virtual reality (VR) and augmented reality (AR) technologies are having a profound impact on a variety of marketing practices and are attracting increasing attention from marketing researchers. In this article, we review developments in VR/AR applications and research in the area of consumer marketing. We propose a conceptual framework for VR/AR research in consumer marketing that centers around consumer experiences provided by VR/AR applications along the customer journey and the effectiveness of such applications, and delve into the key concepts and components of the framework. Next, we provide a comprehensive overview of VR/AR applications in current practices and extant researc…

Elapsed time on first buying triggers brand choices within a category: A virtual reality-based study

2016

This study integrates neuroscientific tools such as data from eye movements, store navigation, and brand choice in a virtual supermarket into a single source data analysis to examine consumer choice, customer experience, and shopping behavior in a store. Through qualitative comparative analysis, the findings suggest that a high level of attention to a brand and slow eye movements between brands lead to additional brand purchases within the product category. This study points out that the key driver of additional brand choices is the time buyers spend on the first choice, showing that the allocation of less for the first choice triggers additional purchases Within the product category and, t…

Brands as relationship builders in the virtual world: A bibliometric analysis

2020

Abstract Given the growing role of brands as relationship partners and relationship facilitators and the pre-eminence of the online environment for consumers, this article contributes to the understanding of virtual brand-centric relationships by presenting the first bibliometric mapping analysis of the academic research into the topic from its conception until 2018. Using keyword co-occurrence, it examines 585 records and identifies the most productive countries, journals, influential authors and papers, and research clusters. With 96% of the published records appearing between 2010 and 2018, this analysis revealed that the field is emergent. The research primarily originates from authors …

The virtuous cycle of stakeholder engagement in developing a sustainability culture: Salcheto winery

2020

Abstract Stakeholder engagement in sustainability represents a powerful driver for value creation. Drawing from stakeholder theory, this paper explores how a firm with a proactive sustainable behaviour engages stakeholders in developing innovation and creating value. A longitudinal, single case study of the Salcheto winery was carried out. Since the late 1990s, Salcheto has been at the forefront of wine eco-innovation and it has played a key role in the development of Montepulciano (Tuscany, Italy) as one of the first sustainable wine clusters worldwide. The development of a sustainable wine culture is one of the firm's various innovations. In doing so, the firm has had to face three challe…

Riannodare il passato e il presente con la restituzione prospettica: ricostruzione della perduta chiesa delle Stimmate di Palermo da foto d’archivio

2020

La restituzione prospettica appartiene di diritto al corpus disciplinare della geometria descrittiva, come problema inverso della prospettiva. In passato tale tecnica è stata utilizzata ben poche volte per la ricostruzione da immagini fotografiche di architetture e opere d’arte perdute; gli strumenti digitali per la rappresentazione offrono però l’opportunità di recuperare la restituzione prospettica come strumento efficace per la ricostruzione di monumenti perduti ritratti in foto d’epoca. Il caso studio prescelto è la chiesa delle Stimmate di Palermo, demolita alla fine del XIX secolo per la costruzione del Teatro Massimo. La chiesa ad aula era delimitata da pareti con nicchie arcuate poc…
