Memoria e coscienza storiografica nella “praefatio” all’«Ystoriola Langobardorum Beneventum degen-tium» di Erchemperto

2023

In this intervention the reading of the "praefatio" at the «Ystoriola Langobardorum Beneventum degentium» by Erchempert, a Lombard historian of the IXth century, is conducted. The examination allows us to observe, as a preliminary, a historian of the High Middle Ages at his “work table”, in the reference to the sources and models and, at the same time, in the clear awareness of the innovative elements that he proposes to highlight through the story of the tragic and fatal decline of the Lombard people of southern Italy. To this are added other connotations that refer to a precise historiographical awareness, such as the high judgment of himself, the profession of truthfulness of the narrati…

Apprendere una seconda lingua da analfabeti tra ricerca e didattica. Una esperienza con i minori stranieri non accompagnati a Palermo

This contribution presents data and experiences acquired within the frame of the “Inclusion Project Linguistic School of Italian Language for Foreigners” of the University of Palermo. The program, created five years ago, has designed and managed educational courses for adults and unaccompanied minors (msna) of low and very low schooling level, most of them between 16 and 18 years old, and developed a series of social initiatives related to the insertion of these minors in Sicilian Society. These youths are part of a large number of unaccompanied adolescents who, in recent years, have come ashore to the port of Palermo along with thousands of refugees and asylum seekers. A significant number…

L’importanza dei prerequisiti e dello screening precoce nella scuola dell’infanzia

2016

Questo contributo si propone di sottolineare l’importanza di alcune competenze cognitive, detti prerequisiti, che sono implicate nell’acquisizione delle abilità di lettura e scrittura come ad esempio: la conoscenza dell’alfabeto; la consapevolezza fonologica; la denominazione rapida automatica (RAN); la memoria fonologica e la processazione visiva. Numerose ricerche, anche internazionali, mostrano l’importanza dell’esercizio di tali abilità all’interno della scuola dell’infanzia anche ai fini della prevenzione dello sviluppo di difficoltà di apprendimento e/o di veri e propri disturbi nella successiva carriera accademica del bambino. Inoltre, la realizzazione di interventi didattici mirati …

Channel Gain Cartography via Mixture of Experts

2020

In order to estimate the channel gain (CG) between the locations of an arbitrary transceiver pair across a geographic area of interest, CG maps can be constructed from spatially distributed sensor measurements. Most approaches to build such spectrum maps are location-based, meaning that the input variable to the estimating function is a pair of spatial locations. The performance of such maps depends critically on the ability of the sensors to determine their positions, which may be drastically impaired if the positioning pilot signals are affected by multi-path channels. An alternative location-free approach was recently proposed for spectrum power maps, where the input variable to the maps…

Aerial Spectrum Surveying: Radio Map Estimation with Autonomous UAVs

2020

Radio maps are emerging as a popular means to endow next-generation wireless communications with situational awareness. In particular, radio maps are expected to play a central role in unmanned aerial vehicle (UAV) communications since they can be used to determine interference or channel gain at a spatial location where a UAV has not been before. Existing methods for radio map estimation utilize measurements collected by sensors whose locations cannot be controlled. In contrast, this paper proposes a scheme in which a UAV collects measurements along a trajectory. This trajectory is designed to obtain accurate estimates of the target radio map in a short time operation. The route planning a…

Social Media Data in an Augmented Reality System for Situation Awareness Support in Emergency Control Rooms

2021

AbstractDuring crisis situations, emergency operators require fast information access to achieve situation awareness and make the best possible decisions. Augmented reality could be used to visualize the wealth of user-generated content available on social media and enable context-adaptive functions for emergency operators. Although emergency operators agree that social media analytics will be important for their future work, it poses a challenge to filter and visualize large amounts of social media data. We conducted a goal-directed task analysis to identify the situation awareness requirements of emergency operators. By collecting tweets during two storms in Germany we evaluated the usefu…

The Psychology of Fluent Use

2016

In a perfect world, it would always be possible to operate technology effortlessly and to reach the desired goal. However, in the real world many factors may make technologies difficult to use or even hinder people from using technical artefacts. Most of these factors pertain to usability (i.e., technology’s ability to fit users’ capabilities) and thus concern technological solutions from the point of view of human beings as users of technology. Therefore, designing technical artefacts that are easy to use requires understanding the psychological and mental preconditions for using technology.

How Are Situation Picture, Situation Awareness, and Situation Understanding Discussed in Recent Scholarly Literature?

2019

There are several different definitions of situation awareness. However, all of them have in common is knowing and understanding of what is happening, an understanding of future changes or problems, and the prediction of the future situation and the decisions to be made on its basis. Situation picture and Situation Awareness are narrow. Situation understanding of the situation is the understanding of the decision-makers and their assistants about what has happened, the circumstances that have affected them, the goals of the different parties and the possible development options of the events needed to make decisions on a particular issue or subject. The results of this study indicate that t…

Supporting Inter-Agency Collaboration in Emergency Management: Recurring Challenges Relevant for CSCW

2023

Emergency management requires effective collaboration between different agencies. This work implies several challenges due to a heterogeneous mix of actors with different procedures, practices, and support tools. Despite being focused in various research streams, emergency responders still report challenges with sharing information and establishing shared situational awareness in responding to complex events. The paper presents results from a large-scale digital tabletop exercise that illustrate recurring challenges related to support for collaborative procedures, a communication network structure combining several media, use of geocollaborative tools, and configuration of collaborative env…

Understanding Situational Disabilities and Situational Awareness in Disasters

2019

In this paper, a scenario-based approach augmented with personas typically used in universal design and interactive design domains is used to illustrate the occurrence of situational disabilities in emergency situations, and to show how environmental factors can trigger these situational disabilities. With the help of personas representing selected archetypical characteristics and roles, the scenarios are further examined to show how these situational disabilities can affect the situational awareness of different stakeholders, not only in the command and control centers, but also first responders in the field as well as affected members of the public. This approach provides a better underst…
