Information, Communications and Media Technologies for Sustainability: Constructing Data-Driven Policy Narratives
2021
This paper introduces the idea of data-driven narratives to examine how the use of information, communications, and media technologies (ICMTs) impacts the sustainable growth of economies. While ICMTs have regularly been advocated as a policy tool for growth and development, there is a research gap in empirical studies validating how such policies may be effective. This analysis is based on historical panel data from 39 economies across the developed North (19) and developing South (20). The industry-standard Cross-Industry Standard Process for Data Mining (CRISP-DM) methodology was applied to construct narratives that weave extant theories with empirical data. The art of developing data-dri…
Unlocking mixed oxides with unprecedented stoichiometries from heterometallic metalorganic frameworks for the catalytic hydrogenation of CO 2
2021
[EN] Their complex surface chemistry and high oxygen lattice mobilities place mixed-metal oxides among the most important families of materials. Modulation of stoichiometry in mixed-metal oxides has been shown to be a very powerful tool for tuning optical and catalytic properties. However, accessing different stoichiometries is not always synthetically possible. Here, we show that the thermal decomposition of the recently reported metal-organic framework MUV-101(Fe, Ti) results in the formation of carbon-supported titanomaghemite nanoparticles with an unprecedented Fe/Ti ratio close to 2, not achievable by soft-chemistry routes. The resulting titanomaghemite phase displays outstanding catal…
To correct or to cooperate : Mediational processes and L2 development
2018
The present article argues for a conceptual distinction between corrective feedback and mediation that emphasizes the status of the latter not as an instructional practice but as a defining feature of human psychology (Vygotsky, 1987) that has direct implications for how instruction might be approached. Specifically, Sociocultural Theory (SCT) posits that humans are always and everywhere mediated, as individuals draw upon meanings and ways of thinking they have already internalized as well as those that are available in their immediate environment to regulate their actions. With regard to second language (L2) education, rather than exclusively focusing on learner independent performance or…
Guiding and assessing development of L2 writing process : the role of peer collaboration
2022
This study, informed by Vygotskian notion of mediation and reporting on a partnership between a researcher (the first author) and a teacher (the second author), aims at exploring how peers’ comments can inform teacher assessment and guidance of learners’ L2 (second/foreign language) writing. The participants were 19 L2 English learners in an upper secondary school in Finland. We largely focus on the notes that one pair of learners made on each other’s essays and how they responded to peer assistance. Triangulating these data with classroom observation and a questionnaire, we traced how learners co-constructed their understanding of how their texts can be developed. The foci and how the iden…
Resolving tensions caused by high-stakes assessment in an L2 classroom through mediation
2022
The Finnish classroom assessment culture is considered that of assessment for learning. The situation in upper-secondary schools is different, however. While teachers in Finland appreciate assessment supporting learning, they feel unable to merge it with assessment of learning outcomes, and favour the latter due to the Matriculation Examination (ME; e.g. Leontjev, submitted), a high-stakes exam growingly used in university admission. Learners, likewise, expect teachers to prepare them for the ME (Lakkala & Ilomäki, 2013), the results of which play a significant role in their further studies. The tension between assessment for learning and exam preparation is, therefore, often resolved i…
Geometrical-mechanical artefacts mediating tangent meaning: the Tangentograph
2012
This work deals with the didactical use of geometrical-mechanical artefacts to acquire tangent concept in vygotskian perspective. We adopt Rabardel’s theory on instru-mental approach to distinguish artefacts and instruments specially to evince the history-to-education ontogenesis-phylogenesis process. From this point of view we trace a historical-epistemological pathway for the tangent up to set an ad hoc didactical counterpart. Specifically in this paper we deepen the kinematical properties of the tangent (introducing the XVII century so called tractional motion) designing a laboratorial didactic pathway for 12th grade students with the use of a particular geometrical-mechanical artefact f…
Il problema della definizione della "illiceità"della mediazione nel nuovo reato di traffico di influenze illecite
2022
Le modifiche apportate al delitto di traffico d’influenze illecite ad opera della legge n. 3/2019 hanno accentuato il deficit di determinatezza che già caratterizzava la fattispecie sin dalla sua introduzione, delineando un modello di incriminazione incapace di selezionare le condotte di intermediazione penalmente rilevanti distinguendole dalla attività di lobbying consentita. Il lavoro analizza la specifica questione dell’interpretazione del predicato di “illiceità” della mediazione esaminando le diverse tesi proposte in dottrina e in giurisprudenza. Conclusivamente, l’Autore ritiene che l’interpretazione restrittiva dell’art. 346-bis c.p., che inquadra la fattispecie come delitto “avampos…
Structuration du territoire bourguignon : de l'île à l'isthme
2006
Three principles govern the structuration of the burgundian territory. Its internal organization, with the peripheral location of its most active areas, is similar to the organization of an island. Its situation within national and European space makes it an area of multiple transitions, an unsettled organization, submissive to strong centrifugal forces which can threaten its unity. Lastly, it has always been crossed by numerous links, it is an intermediate space between nodes, strongly marked with networks and exogenous traffic which criss-cross its territory.
Search for photonic signatures of gauge-mediated supersymmetry in 8TeV pp collisions with the ATLAS detector
2015
A search is presented for photonic signatures motivated by generalized models of gauge-mediated supersymmetry breaking. This search makes use of 20.3 fb[superscript −1] of proton-proton collision data at √s = 8 TeV recorded by the ATLAS detector at the LHC, and explores models dominated by both strong and electroweak production of supersymmetric partner states. Four experimental signatures incorporating an isolated photon and significant missing transverse momentum are explored. These signatures include events with an additional photon, lepton, b-quark jet, or jet activity not associated with any specific underlying quark flavor. No significant excess of events is observed above the Stand…
