Microplastics in the global aquatic environment: Analysis, effects, remediation and policy solutions
2019
This opinion paper reports on Microplastics (MPs) pollution in the aquatic environment. MPs are a global problem being detected everywhere: marine environment, wastewaters, surface waters, soils, sediments, food and air. MPs can also absorb organic contaminants, and can be ingested by organisms and introduced into the food web. MPs can be a vector as well of pathogens whereas airborne fibrous MPs may enter our respiratory system with risk to the environment and humans. Main issues and gaps related to MPs on-going and future research are highlighted: chemical analysis, fate in wastewater and drinking water treatment plants, environmental and human health effects as well as remediation strate…
COMPORTAMENTO DI IMPALCATI DA PONTE A CASSONE IN ACCIAIO-CALCESTRUZZO CON ANIMA ONDULATA
2013
La memoria riguarda il comportamento di un impalcato di ponte stradale a cassone avente le anime sagomate secondo una sinusoide, con soletta in c.a. collaborante. L'impalcato presenta schema statico longitudinale di trave continua su 4 appoggi. The paper concerns the behaviour of a box-girder bridge deck road having a steel box and a concrete slab. The steel webs are shaped according to a sine wave. The deck has a width of 13.70 m and a length of 182 m, with the longitudinal static scheme as a continuous beam on four supports. The study highlights the reliability of this constructive solution.
Disparate movement behavior and feeding ecology in sympatric ecotypes of Atlantic cod
2021
Abstract Coexistence of ecotypes, genetically divergent population units, is a widespread phenomenon, potentially affecting ecosystem functioning and local food web stability. In coastal Skagerrak, Atlantic cod (Gadus morhua) occur as two such coexisting ecotypes. We applied a combination of acoustic telemetry, genotyping, and stable isotope analysis to 72 individuals to investigate movement ecology and food niche of putative local “Fjord” and putative oceanic “North Sea” ecotypes—thus named based on previous molecular studies. Genotyping and individual origin assignment suggested 41 individuals were Fjord and 31 were North Sea ecotypes. Both ecotypes were found throughout the fjord. Seven …
A DIGITAL BEHAVIOURAL ASSESSMENT APPLICATION TO APPLY POSITIVE BEHAVIOUR SUPPORT IN SCHOOL WIDE INTERVENTION
2018
The Behavioural Assessment to improve School Environment (BASE) European Erasmus+ project responses to the European requirement of reforming the whole scholastic disciplinary system identifies in the proven US-born concept of the Positive Behaviour Support (PBS) one possible solution, and tries to adapt its practical and evidence-based principles to the heterogeneous European school settings. Recently, scientific studies (Sugai, Horner, 2016) have emphasized the promising role of PBS in reducing the occurrence of behavioural problems by setting up a preventive, proactive and multilevel system based on the direct involvement of the entire school team: starting from teachers, school leaders u…
The poetry of the web : online ethnography of ordinary poets
2021
Through the observation of blogs, online reviews and accounts and profiles on Facebook and Twitter, this research is devoted to the online poetic activities of French-speaking poets (Belgium, France, Quebec, Switzerland). This research work is guided by a simple and general question: how do poets invent their own ways of making poetry with the web? I was interested in poetry being done empirically by focusing on observation, data collection and encounters with poets in an approach inspired by ethnographyGoing beyond the separation between amateurs and professionals, the analysis follows the interactions between these ordinary poets and the tools of the web. During learning, settling into th…
La tesis de Weber en torno al capitalismo en el 500 Aniversario de la Reforma Protestante
1970
La tesis de Weber respecto a una hipotética huella del protestantismo en el «espíritu» del capitalismo ha sido ampliamente difundida. Sin desmerecer su planteamiento (la indemostrabilidad no resta verosimilitud), lo cierto es que, siendo una hipótesis difícilmente falsable, de ella han derivado formulaciones poco cuidadosas que vendrían a justificar las actuales circunstancias económicas con hechos religiosos diferenciales. Siendo la religión un hecho omniabarcador sin igual, tales circunstancias dependen de muchos factores. Se ha pretendido conferirle validez científica a partir de datos socioeconómicos de lo más variado. Algo aplicable también a quienes pretenden refutarle. La intoxicació…
Coalescing directed random walks on the backbone of a 1 +1-dimensional oriented percolation cluster converge to the Brownian web
2018
We consider the backbone of the infinite cluster generated by supercritical oriented site percolation in dimension 1 +1. A directed random walk on this backbone can be seen as an "ancestral line" of an individual sampled in the stationary discrete-time contact process. Such ancestral lineages were investigated in [BCDG13] where a central limit theorem for a single walker was proved. Here, we consider infinitely many coalescing walkers on the same backbone starting at each space-time point. We show that, after diffusive rescaling, the collection of paths converges in distribution to the Brownian web. Hence, we prove convergence to the Brownian web for a particular system of coalescing random…
Spoken conversational context improves query auto-completion in web search
2021
Web searches often originate from conversations in which people engage before they perform a search. Therefore, conversations can be a valuable source of context with which to support the search process. We investigate whether spoken input from conversations can be used as a context to improve query auto-completion. We model the temporal dynamics of the spoken conversational context preceding queries and use these models to re-rank the query auto-completion suggestions. Data were collected from a controlled experiment and comprised conversations among 12 participant pairs conversing about movies or traveling. Search query logs during the conversations were recorded and temporally associated…
A Methodological Approach for Developing and Validating a Parsimonious and Robust Measurement Tool: The Academic E-Service Quality (ACEQUAL) Model
2021
Nowadays, in the higher education sector, the quality measurement process of education-related services is assuming a crucial role to support focused and targeted improvement activities deeply centered on students’ needs/necessities. These are considered crucial factors for dealing with the current academic competitive context. Therefore, the quality measurement process has to be precise and accurate, namely the measurement model on which it is based has to be parsimonious and robust. The present work proposes an effective and easy-to-use methodological approach suitable for supporting the structuring of a measurement tool. Its effectiveness is shown with reference to the academic e-service…
