TeamSim: An Educational Micro-World for the Teaching of Team Dynamics

2008

In this paper we present an educational micro-world in which a learner can manipulate variables affecting the efficiency with which a team adapts to its environment. These include the structure of hierarchical relations within the team, the structure of the communications network, and other environmental parameters. Using the micro-world, the learner can design experiments (simulations) exploring notions in the dynamics of small groups. A freeware version of TeamSim is available from http:// laral.istc.cnr.it/gigliotta/.

Plasticity of retinal ribbon synapses.

1996

Ribbon synapses differ from conventional chemical synapses in that they contain, within the cloud of synaptic vesicles (SV's), a specialized synaptic body, most often termed synaptic ribbon (SR). This body assumes various forms. Reconstructions reveal that what appear as rod- or ribbon-like profiles in sections are in fact rectangular or horseshoe-shaped plates. Moreover, spherical, T-shaped, table-shaped, and highly pleomorphic bodies may be present. In mammals, ribbon synapses are present in afferent synapses of photoreceptors, bipolar nerve cells, and hair cells of both the organ of Corti and the vestibular organ. Synaptic ribbons (SR's) are also found in the intrinsic cells of the third…

One is not enough: On the effects of reference genome for the mapping and subsequent analyses of short-reads.

2020

Mapping of high-throughput sequencing (HTS) reads to a single arbitrary reference genome is a frequently used approach in microbial genomics. However, the choice of a reference may represent a source of errors that may affect subsequent analyses such as the detection of single nucleotide polymorphisms (SNPs) and phylogenetic inference. In this work, we evaluated the effect of reference choice on short-read sequence data from five clinically and epidemiologically relevant bacteria (Klebsiella pneumoniae, Legionella pneumophila, Neisseria gonorrhoeae, Pseudomonas aeruginosa and Serratia marcescens). Publicly available whole-genome assemblies encompassing the genomic diversity of these species…

Zinc accumulation in the telencephalon of lizards.

1987

The zinc concentration in the brains of two species of lizard was determined by atomic-absorption spectrophotometry. The zinc concentration was found to be highest in the telencephalon of Lacerta galloti (21.1 micrograms/g fresh weight) and Podarcis hispanica (16.77 +/- 0.8 micrograms/g) while the mesencephalon and brain stem exhibited lower zinc concentrations, i.e., 7.0 micrograms/g in Lacerta galloti and 6.08 +/- 0.4 micrograms/g in Podarcis hispanica. This high telencephalic concentration of zinc is paralleled by intense and well-defined Timm reactivity used for demonstrating the presence of zinc-containing boutons at the light-microscope level. Volumetric-densitometric studies of these…

Abitare nel reale. Dalla crisi della periferia alla tessitura di nuove relazioni contestuali

2019

I progetti redatti per “Palermo Sud-Est” sono il risultato di un Laboratorio di Laurea strutturatosi attraverso incontri, seminari, comunicazioni specialistiche, esposizioni critiche, che – in una strategia condivisa – ha visto ogni studente elaborare il proprio lavoro nel confronto con gli altri attori del Laboratorio stesso. La ricerca sui “progetti urbani” è stata impostata di modo che ogni laureando fosse messo a conoscenza dei progetti svolti nello stesso ambito territoriale dai colleghi che l’avevano preceduto, così da poter operare in continuità e contribuire a formulare un ragionamento unitario, nel quale ogni progetto costituisse continuazione, verifica o anche variante dei precede…

The projects prepared for "Palermo South-East" are the result of a Graduate Laboratory structured through meetings seminars specialist communications critical exhibitions which - in a shared strategy - saw each student elaborate their work in comparison with others actors of the same Laboratory. The research on "urban projects" was set so that each graduating student was made aware of the projects carried out in the same geographical area by the colleagues who had preceded it so as to be able to operate in continuity and contribute to formulating a unitary reasoning in which each project constituted continuation verification or even variant of the previous ones. These coordinated works have pursued two fundamental objectives: the strengthening of infrastructures and the establishment of specialized public buildings with superior functions aimed at requalifying and regenerating various critical situations with particular attention to the relationship between context and life scenarios. Thus each designer while dealing with a main functional program simultaneously deals with various issues such as the rationalization of the road system the redevelopment of existing buildings the design and refunctionalization of urban services (for example the transformed Central Station in the hotel or the project of a great Mosque)several degree theses have addressed as the main theme or as a question in the background the design of a new bed for the Oreto river and the relative establishment of a park facing it. In this desire to "patch up the wounds" in the different areas of "Palermo South-East" in close relationship with the vicissitudes of the place there is a continuous reference to architectures of all time and some questions involving the functional program are suggested - that identifies the character (or perhaps "type") of what is to be inserted in a given context - and the qualities of living reality as a pivotal material in the design process.Settore ICAR/14 - Composizione Architettonica E Urbana

Seeing reality through Einstein's eyes: a teaching proposal for special relativity

2021

The teaching of Special Relativity is still a critical issue not only for students but also for teachers. In this paper, we describe the trial of a learning unit on the Special Relativity topic based on Minkowski's approach through spacetime diagrams, following the results in pedagogical researches in this field. The main innovation of our project consists of a mechanical instrument: it allows to physically and mechanically represent Lorentz’s transformations by hands, exploring the effects of a change of the reference frame. Teachers and students can deal “by eye” with unusual phenomena as the loss of simultaneity, time dilation, length contraction, relativistic addition of velocities and …

Measurement of the Convective Heat-Transfer Coefficient

2014

We propose an experiment for investigating how objects cool down toward the thermal equilibrium with its surrounding through convection. We describe the time dependence of the temperature difference of the cooling object and the environment with an exponential decay function. By measuring the thermal constant tau, we determine the convective heat-transfer coefficient, which is a characteristic constant of the convection system.
