GLOBE BASED 3D GIS SOLUTIONS FOR VIRTUAL HERITAGE
2018
Abstract. During the last years, many solutions have been proposed for 3D Virtual Heritage representations. Recently, also new technologies for online gaming evolved, based on javascript libraries (WebGL), used to create and publish virtual interactive environments. They are based on recent Web browser’s functionalities, surpassing some limitations of VRML technologies. On the side of geospatial information, technology has evolved from desktop GIS to 2D WebGIS and globe applications. The use of globe applications is, today, very diffused due to its immediate and at the same time impressive representation of the earth surface and territories. These technologies have been, also, applied to Vi…
PRACTICAL APPROACH FOR HYPERSPECTRAL IMAGE PROCESSING IN PYTHON
2018
Abstract. Python is a very popular programming language among data scientists around the world. Python can also be used in hyperspectral data analysis. There are some toolboxes designed for spectral imaging, such as Spectral Python and HyperSpy, but there is a need for analysis pipeline, which is easy to use and agile for different solutions. We propose a Python pipeline which is built on packages xarray, Holoviews and scikit-learn. We have developed some of own tools, MaskAccessor, VisualisorAccessor and a spectral index library. They also fulfill our goal of easy and agile data processing. In this paper we will present our processing pipeline and demonstrate it in practice.
Emotion Elicitation: A Comparison of Pictures and Films
2016
Abstract Pictures and film clips are widely used and accepted stimuli to elicit emotions. Based on theoretical arguments it is often assumed that the emotional effects of films exceed those of pictures, but to date this assumption has not been investigated directly. The aim of the present study was to compare pictures and films in terms of their capacity to induce emotions verified by means of explicit measures. Stimuli were (a) single pictures presented for 6 s, (b) a set of three consecutive pictures with emotionally congruent contents presented for 2 s each, (c) short film clips with a duration of 6 s. A total of 144 participants rated their emotion and arousal states following stimulus …
Effectuation Logic in Digital Business Model Transformation : Insights from Japanese High-Tech Innovators
2019
Purpose The purpose of this paper is to study how digital business models evolve when entrepreneurs move to new digital platforms and how this evolution is related to effectuation and causation logics. Design/methodology/approach This study applies a multiple case study approach to investigate how digital business models change in small, Japanese high-tech firms providing their innovations through different digital platforms. To investigate digital business models, this study considers the elements that comprise general business models. The case firms were selected based on size, products and transitions from physical to various digital platforms. Semi-structured interviews were conducted …
Modelling Without a Modelling Language
2018
Developments in computer hardware and programming languages, in this case C++, have made it feasible to write models of concurrent systems under verification in the programming language, instead of some established modelling language such as Promela. While this does not reduce the usefulness of modelling languages, it offers new possibilities that may be advantageous, for instance, when teaching state space ideas to newcomers or when experimenting with new scientific ideas. In earlier work, we were able to express everything else fairly naturally in C++, except the set of transitions. The present study uses C++ lambda functions to represent naturally transitions that consist of a tail state…
A Novel Bio-Inspired Approach for High-Performance Management in Service-Oriented Networks
2021
Service-continuity in distributed computing can be enhanced by designing self-organized systems, with a non-fixed structure, able to modify their structure and organization, as well as adaptively react to internal and external environment changes. In this paper, an architecture exploiting a bio-inspired management approach, i.e., the functioning of cell metabolism, for specialized computing environments in Service-Oriented Networks (SONs) is proposed. Similar to the processes acting in metabolic networks, the nodes communicate to each other by means of stimulation or suppression chains giving rise to emergent behaviors to defend against foreign invaders, attacks, and malfunctioning. The mai…
RAÍCES MITOLÓGICAS EN LA ICONOGRAFÍA DE LA BELLA DURMIENTE EL CASO DE LA BELLA DURMIENTE DE WALT DISNEY
2020
Sleeping Beauty is a story we can all tell. A cursed princess who pricks herself and falls into a deep sleep until her prince wakes her up. But, like all stories, she has evolved into this form. If we trace its origins, the first time it was put down on paper was in the 13th century. Later, in the 14th century, three more versions were added. In the 17th century Giambattista Basile popularized it, but in that same century Perrault adapted it to his own way and in the 19th century the Brothers Grimm simplified it. Through all these forms there remains an essence, a common narrative, some characteristic elements that allow us to identify this story as the same one. And in them we …
The Role of e-Tutor Competencies in Postgraduate e-Learning Courses: Spotlight on Emotion Management
2021
The role of e-learning in the existing and challenging educational era is crucial. However, it is necessary to overcome some drawbacks such as feelings of isolation and a lack of emotional contact. In this sense, emotion management is a key driver of student satisfaction in e-learning, which is significantly related to students’ motivation, learning, cognitive strategies, self-regulation, and personality antecedents in the classroom. This article examines an online postgraduate course in financial statements auditing, describing the resources used by the e-tutor to conduct affective tutorials, reduce students’ feelings of isolation, increase student involvement, and achieve success in e-lea…
Using Factor Analysis in Relationship Marketing
2013
Abstract The purpose of the paper is to present a detailed application of the factor analysis technique within the domain of relationship marketing. A comprehensive literature review is undertaken regarding the concept of customer loyalty – an important variable of relationship marketing. Loyalty is defined by its two dimensions – behavioral and attitudinal; the second dimension is understood through the three components of the human psyche: affective, cognitive and conative. Conative Loyalty is measured through four items which are statistically and semantically reduced to two items without a heavy loss of information.
Victims of Racket: Entrepreneurs and Traders Dealing with Cosa Nostra, Ndrangheta, and Camorra
2015
This work proposes research on a still unexplored psychical world: thoughts, emotions, and real events experienced by racket victims of the three largest criminal organizations of the South of Italy: Mafia, Camorra, and Ndrangheta. The purpose is to understand the multifaceted psycho-anthropological and social issues criminal organizations have settled on, and particularly which psycho-relational dynamics and sociocultural codes come into play in the complex and controversial relationship between victim and criminal system, between victim and support systems. With entrepreneurs and tradesmen victims of organized crime, we have analyzed lived experiences - in particular fear - and psychologi…
