Critical Exploration of Flexible Delivery

2020

This work-in-progress research article presents an introductory qualitative study on students' perceptions of a flexibly delivered, modular computer science course. Many contemporary approaches to education rely in various ways on flexible delivery of course content. This is often done to capitalize on modern technology and the web, and to put the student ‘in the center.' However, it is becoming manifest that these approaches may challenge both the students and the equity between them, making it important to understand the effects of flexible delivery in terms of the students. In the voice of our students, flexible delivery was seen as a largely positive approach, reducing stress, promoting…

Expectations and Experiences of Implementing a Mobile Secure Communication Application

2020

The privacy and security of communication in corporations and governmental organizations has increased enormously over the years. At the same time, a growing amount of technological solutions to support this have emerged. This study examines user expectations before and use experiences during the implementation phase of a mobile secure communication application. These are investigated from the expectation–confirmation perspective and its influence on continued adoption. The study has an exploratory approach for this investigation. To guide the investigation, the study draws from the expectation–confirmation theory (ECT) and the unified theory of acceptance and use of technology (UTAUT). Emp…

Towards Measuring the Agility of Software Business

2018

Agile development methods have been employed across the software industry. However, it is not always clear if the used methods actually help the software firms in being more agile and if agility has a positive influence in the software firm performance. Studying these questions may turn out impossible since good measurements for assessing the overall agility of software firms do not yet exist. A need is therefore detected to measure the differences in agility between firms and finding the means to evaluate the differences in agility in reliable manner. This article examines how to measure the agility of a software firm and reports initial steps in the process of developing measurement instr…

Interactively Learning the Preferences of a Decision Maker in Multi-objective Optimization Utilizing Belief-rules

2020

Many real life problems can be modelled as multiobjective optimization problems. Such problems often consist of multiple conflicting objectives to be optimized simultaneously. Multiple optimal solutions exist to these problems, and a single solution cannot be said to be the best without preferences given by a domain expert. Preferences can be used to find satisfying solutions: optimal solutions, which best match the expert’s preferences. To model the preferences of the expert, and aid him/her in finding satisfying solutions, a novel method is proposed. The method utilizes machine learning combined with belief-rule based systems to adaptively train a belief rule based system to learn a domai…

La valeur économique des paysages des villes périurbanisées

2007

La recherche présentée ici propose une méthode de description et d’évaluation des caractéristiques d’un paysage qui combine la géographie quantitative et l’économétrie des modèles hédoniques. Un modèle géographique produit des indices caractérisant les paysages à partir d’une reconstitution de la vue depuis le sol, en tenant compte des effets du relief et des masques que les objets hauts opposent à la vue. Il décrit la quantité de paysage vu par un observateur au niveau du sol en la répartissant entre 13 types d’occupations du sol. Les variables produites par le modèle géographique sont utilisées dans des régressions hédoniques qui permettent d’évaluer l’impact des attributs paysagers ain…

Mapping of Biomass Residues for Potential Energy Generation from the Wine-Growing Sector in the Provinces of Palermo and Trapani

2019

This paper is based on results obtained during the project Vienergy (Interreg Italia-Malta programme 2007-2013) and contains data on the potential energy generation of biomass residues following pruning from vineyards located within the provinces of Trapani and Palermo. Analysis of the energy potential, following microgasification tests and heat production related to the biomass, included a preliminary mapping of vineyards in the area and an assessment of the total biomass available. Vineyard mapping was carried out using remote-sensing technologies: images were acquired and analysed using Landsat satellite; spectroradiometric calibration then took place using various targets obtained from …

A Systematic Literature Review and Analysis of Mobile Retailing Adoption

2019

The purpose of this study is to provide a comprehensive updated review and analysis of mobile retailing adoption. Although research on mobile channel utilization has increased significantly in recent years and many new studies on this topic have been published, research has not yet provided a clear structure regarding how consumers’ expectations have advanced in relation to mobile retailing adoption. Thus, this study synthetizes the mobile retail adoption literature and develops a framework for it. Our systematic literature review analyzed 94 scientific articles that were published between 2010 and 2018 to determine customers’ different expectations and demands during different mobile chann…
