Competition Logics during Digital Platform Evolution

2018

How are platforms built and how do they evolve? This is a salient question in digital ecosystems, where the competition has moved from traditional one-sided business logics to multi-sided platforms. In this paper, we explore how a digital platform evolves when the organization of the multilayered platform architecture, and related control points, is modified through competitive moves. We also examine how a firm may be able to manage the increased complexity of the platform. We show that when technical and strategic bottlenecks are solved, the platform owner can expand control to strategically important layers of the platform stack. The findings indicate that the complexity of the platform i…

The importance of the inland leg of containerised maritime shipments: An analysis of modal choice determinants in Spain

2011

Abstract While most of the studies that address competition between road and rail transport focus on national or international non-maritime shipments, there is practically no empirical evidence on the modal choice determinants of the inland leg of maritime shipments. This paper intends to fill that gap by estimating a modal choice model between road and rail transport on the inland leg of Spanish containerised maritime freight shipments, using a mixed logit model and stated preference techniques. The results obtained confirm the vital role that frequency plays in the relative competitiveness of rail transport and also provide subjective values of transport attributes that are deemed essenti…

Effect of low-impact aerobic exercise combined with music therapy on patients with fibromyalgia. A pilot study.

2016

Abstract Objective Fibromyalgia is a pathological entity characterized by chronic widespread musculoskeletal pain and the presence of "tender points". It constitutes a significant health problem because of its prevalence and economic impact. The aim of the present study was to determine the therapeutic benefits of low impact aerobic exercise alone or in combination with music therapy in patients with fibromyalgia. Methods A single-blind randomized controlled pilot trial was performed. Thirty-five individuals with fibromyalgia were divided into three groups: (G1) therapeutic aerobic exercise with music therapy (n=13); (G2) therapeutic aerobic exercise at any rhythm (n=13) and (CG) control (n…

Digital information receiver based on stochastic resonance

2003

International audience; An electronic receiver based on stochastic resonance is presented to rescue subthreshold modulated digital data. In real experiment, it is shown that a complete data restoration is achieved for both uniform and Gaussian white noise.

Experimental investigation on the effectiveness of basalt-fibre strengthening systems for confining masonry elements

L’impiego di materiali compositi per il rinforzo di colonne in muratura è diventato una pratica ampiamente diffusa nel corso degli ultimi decenni. Questa tecnica, che consiste generalmente nell’applicazione di materiali polimerici fibrorinforzati (Fibre Reinforced Polymer-FRP), ha mostrato buone potenzialità, essendo in grado di garantire notevoli incrementi di resistenza e duttilità dell’elemento rinforzato, grazie ad un’azione di confinamento passivo. Tuttavia, l’impiego di compositi a matrice polimerica presenta alcuni limiti legati soprattutto alle prestazioni delle resine epossidiche, che a causa della loro natura sintetica danno luogo a problemi di compatibilità con il supporto murari…

Learning to Read in a Digital World

Encouraging and verifying critical thinking skills through the reading process

2017

La competenza di lettura è un punto di partenza imprescindibile per migliorare abilità di analisi, valutazione, sintesi, interessate pure nella promozione della competenza digitale. Questo lavoro si propone di accertare la validità di un percorso formativo incentrato sull’uso di strategie di lettura per lo sviluppo del pensiero critico. Ci si chiede soprattutto se e come leggere testi usando il formato elettronico favorisca nello studente attività di interpretazione, formulazione di giudizi ed espressione di idee originali. Nella prima parte del lavoro è presentato l’oggetto di studio. Nella seconda parte è descritta la metodologia di ricerca, che mette in pratica le risultanze scientifiche…

Use of wavelet for image processing in smart cameras with low hardware resources

2013

International audience; Images from embedded sensors need digital processing to recover high-quality images and to extract features of a scene. Depending on the properties of the sensor and on the application, the designer fits together different algorithms to process images. In the context of embedded devices, the hardware supporting those applications is very constrained in terms of power consumption and silicon area. Thus, the algorithms have to be compliant with the embedded specifications i.e. reduced computational complexity and low memory requirements. We investigate the opportunity to use the wavelet representation to perform good quality image processing algorithms at a lower compu…

Bodily dimensions of reading and writing practices on paper and digitally

2015

The bodily aspects of reading/writing practices are investigated in Finland.The paper is considered more adaptive to varied reading purposes than the screen.Handwriting is described as a more flexible and relaxed practice than typing.Skills determine less than materials and images the practices of reading/writing.Digital interfaces determine the ways we read and write less than suggested. This article investigates the different shapes in which reading and writing practices occur when paper/pen are compared with keyboard/screen. The focus is on the bodily aspects of these practices. Reading and writing are viewed as techniques of the body, which over the years have become increasingly mediat…

Everyday Appropriations of Information Technology: A Study of Creative Uses of Digital Cameras

2011

Repurposive appropriation is a creative everyday act in which a user invents a novel use for information technology (IT) and adopts it. This study is the first to address its prevalence and predictability in the consumer IT context. In all, 2,379 respondents filled in an online questionnaire on creative uses of digital cameras, such as using them as scanners, periscopes, and storage media. The data reveal that such creative uses are adopted by about half of the users, on average, across different demographic backgrounds. Discovery of a creative use on one's own is slightly more common than is learning it from others. Most users discover the creative uses either completely on their own or wh…
