The Diversification of Sicilian Farms: A Way to Sustainable Rural Development

2021

Rural areas still suffer from a lack of sustainable development, and the diversification of farms may be a step in the right direction. The paper provides a detailed picture of the diversification of Sicilian farms into tourism services. Specifically, we propose a simple indicator of localization intensity of agritourism farms and explore their spatial distribution at municipality level. Our study highlights that Sicilian farms rarely diversify into tourism services, despite being situated in attractive areas. That said, some significant spatial clusters of municipalities where agritourism farms are highly concentrated do emerge from the study.

Fibre break failure processes in unidirectional composites: evaluation of critical damage states

2016

Earlier work which successfully modelled the kinetics of fibre breakage in unidirectional composites under monotonic tensile loading has been extended to quantify the kinetics of fibre failure during both monotonic and sustained tensile loading. In both cases, failure was seen to occur when a critical density of large clusters (more than 16 fibres are broken within the representative volume element) of fibre breaks developed. However, in monotonic loading failure occurred very quickly after the first development of these large clusters, whereas under sustained loading the composite could accommodate greater levels of large clusters because of the lower applied load. This article is part of …

Assessment of cross-flow filtration as microalgae harvesting technique prior to anaerobic digestion: Evaluation of biomass integrity and energy demand

2018

[EN] In the present study, the effect of cross-flow filtration (CFF) on the overall valorization of Chlorella spp. microalgae as biogas was assessed. The effect of CFF on microalgae cell integrity was quantified in terms of viability which was correlated with the anaerobic biodegradability. The viability dropped as the biomass concentration increased, whereas anaerobic biodegradability increased linearly with the viability reduction. It was hypothesized that a stress-induced release and further accumulation of organic polymers during CFF increased the flux resistance which promoted harsher shear-stress conditions. Furthermore, the volume reduction as the concentration increased entailed an …

Response of macrophyte communities and status metrics to natural gradients and land use in boreal lakes

2012

Abstract We studied the relations of aquatic macrophyte communities, ecological quality metrics and water quality to lake characteristics and to land use defined at multiple spatial scales (three lake marginal zones (LMZs) of contrasting width and the whole topographic catchment) in 110 boreal lakes in Finland using ordination and generalised additive modelling. Variation in macrophyte community composition of our lakes was related to water quality, land use, latitude and lake morphology. Relationships of macrophyte status metrics – the proportion of type-specific species (TT50), Percent Model Affinity (PMA) and Trophic Index (TI) – to land use were scale dependent. The proportion of agricu…

Hypervisor-assisted Atomic Memory Acquisition in Modern Systems

2019

Reliable memory acquisition is essential to forensic analysis of a cyber-crime. Various methods of memory acquisition have been proposed, ranging from tools based on a dedicated hardware to software only solutions. Recently, a hypervisor-based method for memory acquisition was proposed (Qi et al., 2017; Martignoni et al., 2010). This method obtains a reliable (atomic) memory image of a running system. The method achieves this by making all memory pages non-writable until they are copied to the memory image, thus preventing uncontrolled modification of these pages. Unfortunately, the proposed method has two deficiencies: (1) the method does not support multiprocessing and (2) the method does…

Le cyberplagiat dans le cadre de l’éducation supérieure espagnole : explorer les causes pour atteindre des solutions concrètes

2018

Ce travail présente une révision théorique sur le concept de cyberplagiat, ainsi que les facteurs qui incitent à tomber dans cette pratique. L’étude propose, ensuite, quelques mesures visant la détection et la prévention de ce phénomène dont les professeurs et les institutions académiques devraient tenir compte pour faire prendre conscience aux étudiants de l’importance de l’originalité des travaux qu’ils présentent. Ainsi, le besoin d’une gestion responsable de l’information disponible en ligne permettant d’atteindre la maturité intellectuelle au niveau académique pour l’appliquer, par la suite, dans le milieu professionnel s’impose. Ces réflexions nous permettront de conclure que, même si…

Developing mixed methods research in sport and exercise psychology: potential contributions of a critical realist perspective

2020

Notwithstanding diverse opinions and debates about mixing methods, mixed methods research (MMR) is increasingly being used in sport and exercise psychology. In this paper, we describe MMR trends within leading sport and exercise psychology journals and explore critical realism as a possible underpinning framework for conducting MMR. Our meta-study of recent empirical mixed methods studies published in 2017–2019 indicates that eight (36%) of the 22 MMR studies explicitly stated a paradigmatic position (five drew on pragmatism, two switched paradigms between qualitative and quantitative elements of the study, and one was situated in relativist-interpretivism). The remaining 14 (64%) studies d…

Agustí Bartra i la negritud

2014

El poeta Agustí Bartra (1908-1982) va ser traductor d’alguns dels poetes neoafricans més importants del segle xx. El present treball vol incidir en les reflexions que, a propòsit d’aquestes traduccions, ens ajuden a configurar la poètica del mateix Bartra. Temes tan centrals com la funcionalitat de la poesia, el seu caràcter soteriològic, el paper del mite o del temps, són presents en Bartra com en alguns dels poetes de la negritud. Més enllà d’un interès antropològic, una efusió exòtica o revolucionària, Bartra acara la poesia neoafricana des de la seva exemplaritat, i supera, d’aquesta manera, els tractaments asimètrics, paternalistes o merament ideològics d’alguns dels qui, des d’Occiden…
