Interactivity, Values and the Microgenesis of Learning in a Tertiary Setting
2016
Student learning is a hot topic in tertiary education circles these days. However, it is not always clear what words like ‘learning’ and ‘learner’ mean. It is important for educationalists to understand learning as it actually occurs in real-time learning situations. We build on Hutchins’ theory of distributed cognition and Gibson’s ecological psychology to show how human learning is an interactive process. We propose Multimodal Event Analysis as a tool for analyzing a University tutorial in which students attempt to solve a problem of regression analysis. We investigate how participants’ multimodal interactivity with the changing affordance arrays of the learning situation is the driver an…
Street Names through Sociological Lenses. Part I: Functionalism and Conflict Theory
2020
Abstract Street names are mundane spatial markers that besides providing a sense of orientation inscribe onto the landscape the ideological ethos and political symbols of hegemonic discourses. This review article takes stock of the existing scholarship done on the politics of street naming practices in human (political, cultural, and social) geography and rethinks these insights from sociological perspectives. Drawing on Randall Collins’ taxonomy of sociological theory, the paper interprets urban street nomenclatures along functionalist, conflictualist, constructionist, and utilitarian lines. The analysis is delivered in two installments: Part I addresses urban nomenclatures from functional…

Catalytic one-handed helix-induction and memory of amphiphilic poly(biphenylylacetylene)s in water
2020
Abstract A series of amphiphilic biphenylylacetylene-based homo- and copolymers (PBPAs) carrying chiral and/or achiral oligo(ethylene glycol) pendants at the 4’-position of the biphenyl units were synthesized and the amplification of the macromolecular helicity through noncovalent and/or covalent chiral interactions followed by the memory of the helicity were investigated in both water and organic solvents. The macromolecular helicity was efficiently induced in the homopolymers of achiral monomers through specific encapsulation of a catalytic amount of hydrophobic chiral guests in water and their induced helicities were stably memorized in water after complete removal of the optically-activ…
Novel Iron(II) Microporous Spin-Crossover Coordination Polymers with Enhanced Pore Size
2012
In this Communication, we report the synthesis and characterization of novel Hofmann-like spin-crossover porous coordination polymers of composition {Fe(L)[M(CN)4]}·G [L = 1,4-bis(4-pyridylethynyl)- benzene and MII = Ni, Pd, and Pt]. The spin-crossover properties of the framework are closely related to the number and nature of the guest molecules included in the pores.
The Taste of Port City. Eat and the City
2013
WaterFood is a column centered on the culture of food dedicated to Port Cities due to the extraordinary richness and beauty of their ‘karstic’ interconnection with cooking; the articles of WaterFood will propose the bliss of the discovery of the beating heart and of the most sincere soul of Port Cities by tasting their flavor, by making the city a living cook book.
Performance evaluation of non volatile memories with a low cost and portable automatic test equipment
2017
This paper presents a versatile and portable test equipment, called portable ATE for research and development of non-volatile memories functionalities. The system is based on STM32-NUCLEO assembled with a custom designed daughter board, in order to host non-volatile memories test-chips, to manage the needed power supplies and generate suitable signals stimuli for correct operations. The system is controlled and programmed by a personal computer, via USB interface. In particular the system can perform: memory reading, writing and erasing, with settings flexibility on time and voltage levels; Electrical Stress Tests (Drain, Gate and Bulk Stress); Cycling Tests; debugging algorithms (erase or …
