Risks of Concurrent Execution in E-Commerce Processes
2021
The development of ICT facilitates replacing the traditional buying and selling processes with e-commerce solutions. If several customers are served concurrently, e.g. at the same time, the processes can interference each other causing risks for both the buyer and the seller. The paper offers a method to identify purchase/sale risks in simultaneous multi-customer service processes. First, an exact model of buying-selling processes is created and the conditions for the correct process execution are formulated. Then an analysis of all the possible scenarios, including the concurrently executed buying-selling scenarios, is performed using a symbolic execution of process descriptions. The obtai…
Architetture di Culotta e Leone nel centro storico di Cefalù: piano, progetto e attuazione
2016
Per gran parte del Novecento gli interventi architettonici nei contesti storici sono stati ricondotti entro i poli della conservazione e trasformazione. In Italia gli anni Ottanta hanno segnato una tappa decisiva nel percorso teorico, metodologico e operativo verso l’approccio richiesto dalle attuali e futuribili condizioni delle aree urbane di antico impianto: guidato da strategie a lungo termine; più responsabile; multiscalare e includente l’intera città contemporanea. L’esperienza di Culotta e Leone nel centro storico di Cefalù, pur costituendo un unicum per il loro ancoramento alla realtà sociale del luogo, fornisce un interessante esempio di continuità tra piano, progetto e attuaz…

Measuring expectation for an affordance gap on a smartphone user interface and its usage among older adults
2020
The smartphone has become a ubiquitous mobile communication tool that plays a crucial role in the daily lives for Malaysian older adults. However, it is not easy for older adults to learn new interaction modes and adopt the smartphone user interface. In this paper, we aim to examine the affordances of a smartphone user interface and its usage by older adults through the lens of Norman’s execution/evaluation action cycle (EEAC) framework. A mobile-user interaction study was administered with four tasks. A paired sample t-test was conducted to analyze the affordance gap between different levels of expectation. The results revealed that three tasks (making phone calls, adding contacts, and usi…
An investigation of the neural circuits underlying reaching and reach-to-grasp movements: from planning to execution
2014
Experimental evidence suggests the existence of a sophisticated brain circuit specifically dedicated to reach-to-grasp planning and execution, both in human and non-human primates (Castiello, 2005). Studies accomplished by means of neuroimaging techniques suggest the hypothesis of a dichotomy between a "reach-to-grasp" circuit, involving the anterior intraparietal area, the dorsal and ventral premotor cortices (PMd and PMv - Castiello and Begliomini, 2008; Filimon, 2010) and a "reaching" circuit involving the medial intraparietal area and the superior parieto-occipital cortex (Culham et al., 2006). However, the time course characterizing the involvement of these regions during the planning …
Long term capacity decisions in uncertain markets for advanced manufacturing systems incorporating scope economies
2002
Abstract By examining the literature in the field of manufacturing flexibility many researchers have located several form of flexibility by distinguishing them into strategic and operational flexibility forms. Furthermore, many measures and design methods have been proposed for flexible manufacturing systems. Surely scope economies are one of the most important strategic form of flexibility in manufacturing systems and their strategic impact has been acknowledged by the very beginning of the flexible manufacturing era. However, despite several researches are available to address scope economies measurement and design methodologies, very few researches investigate their economic convenience …
Market efficiency and the long-memory of supply and demand: is price impact variable and permanent or fixed and temporary?
2016
In this comment we discuss the problem of reconciling the linear efficiency of price returns with the long-memory of supply and demand. We present new evidence that shows that efficiency is maintained by a liquidity imbalance that co-moves with the imbalance of buyer vs. seller initiated transactions. For example, during a period where there is an excess of buyer initiated transactions, there is also more liquidity for buy orders than sell orders, so that buy orders generate smaller and less frequent price responses than sell orders. At the moment a buy order is placed the transaction sign imbalance tends to dominate, generating a price impact. However, the liquidity imbalance rapidly incre…
Motor imagery
2015
International audience; Before participating in a space mission, astronauts undergo parabolic-flight and underwater training to facilitate their subsequent adaptation to weightlessness. Unfortunately, similar training methods can't be used to prepare re adaptation to planetary gravity. Here, we propose a quick, simple and inexpensive approach that could be used to prepare astronauts both for the absence and for the renewed presence of gravity. This approach is based on motor imagery (MI), a process in which actions are produced in working memory without any overt output. Training protocols based on MI have repeatedly been shown to modify brain circuitry and to improve motor performance in h…
Comparison of lower limb segments kinematics in taekwondo kick. an approach to the proximal to distal motion
2015
Abstract In taekwondo, there is a lack of consensus about how the kick sequence occurs. The aim of this study was to analyse the peak velocity (resultant and value in each plane) of lower limb segments (thigh, shank and foot), and the time to reach this peak velocity in the kicking lower limb during the execution of the roundhouse kick technique. Ten experienced taekwondo athletes (five males and five females; mean age of 25.3 ±5.1 years; mean experience of 12.9 ±5.3 years) participated voluntarily in this study performing consecutive kicking trials to a target located at their sternum height. Measurements for the kinematic analysis were performed using two 3D force plates and an eight came…
Especialidades contempladas en la legislación española respecto de la ejecución de la deuda tributaria en los delitos contra la Hacienda Pública
2020
Este es el documento final publicado que se encuentra de forma definitiva en la siguiente URL: https://www.revista-rbd.com/wp-content/uploads/2020/02/12._Antonio_Ferrer_pp._370-391.pdf En el tratamiento del delito fiscal, el procedimiento penal podía determinar la paralización de cualquier acción de la Hacienda Pública en orden al cobro de la deuda tributaria, lo que al margen de generar la idea errónea de que esta deuda se integraba estrictamente en el ámbito de la responsabilidad civil derivada del delito, dificultaba su ejecución determinando un importante agravio comparativo respecto al mero infractor, e incluso frente a un deudor ordinario, adoptándose por ello en nuestra legislación u…
