Tourism Statistics
2017
How a nation collects and shares data on tourism in the country is influenced by that country’s historical, cultural, and political background, as well as its geographical characteristics. This means there are a wide variety of ways tourism data are collected, evaluated, and disseminated. Although standard statistical mechanisms for tracking tourism have been improved, to be of greatest use, statistical sources should be further enhanced and be comparable across locations and time. For this reason, several international organizations have the responsibility of harmonizing definitions of, and methodologies for, collecting data. These organizations are also a relevant supplier of data sources…

Organizāciju cilvēkresursu analītikas attīstības līmenis Eiropā
2018
Cilvēkresursu analītika, kas operē ar datiem lēmumu pieņemšanas procesos, visā pasaulē kļuva par aktuālu tematu. Bakalaura darba mērķis ir izpētīt Eiropas cilvēkresursu analītikas attīstības līmeni un sniegt ieteikumus organizācijām, cilvēkresursu speciālistiem un akadēmiskām iestādēm, lai veiksmīgi ievest cilvēkresursu analītiku. Pētījuma pamatā ir kvalitatīvi dati, kuri tika iegūti intervējot četrus cilvēkresursu speciālistus. Secināts, ka ir būtiska vajadzība pēc cilvēkresursu analītikas un intervētiem organizāciju pārstāvjiem šī tēma ir pazīstama. Galvenais izaicinājums ir saistīts ar profesionālo prasmju trūkumu, tomēr nākotnei cilvēkresursu analītikas cerības ir pozitīvas.
The Role of Big Data in Addressing Societal Challenges: A Systematic Mapping Study
2019
Part 2: Big Data Analytics; International audience; Big data has recently become the focus of academic and corporate investigation due to its high potential in generating business and social value. We have done a systematic mapping of the literature related to big data and its applications leading to social change through the lens of social innovation. The search strategy initially resulted in 593 papers, and after applying inclusion exclusion criteria a total of 156 papers were mapped; 59% of which were identified as empirical studies. This mapping investigated the publication frequency of the studies, research approach and contributions, research areas and article distribution per journal…
Peergrade nella classe capovolta: una piattaforma per favorire il dibattito valutativo e la raccolta di dati statistici sulla valutazione tra pari
2019
Nella “flipped classroom” gli studenti devono spesso studiare determinati argomenti e a redigere presentazioni e relazioni da portare in classe. La valutazione tra pari in tale scenario può svolgere un ruolo importante e migliorare l'efficacia generale dell'apprendimento. Uno strumento molto utile per questo tipo di attività è Peergrade, una piattaforma che integra vari strumenti: realizzazione e condivisione di rubriche di valutazione; sistema di comunicazione tra pari; strumento di assegnazione e consegna di compiti; sistema di valutazione formativa e sommativa. In tre corsi del secondo anno e terzo di Formazione Primaria, in tre diversi atenei (Palermo, Catania, Lumsa), è stato speriment…
Visualizing Confidence in Cluster-based Ensemble Weather Forecast Analyses
2020
In meteorology, cluster analysis is frequently used to determine representative trends in ensemble weather predictions in a selected spatio-temporal region, e.g., to reduce a set of ensemble members to simplify and improve their analysis. Identified clusters (i.e., groups of similar members), however, can be very sensitive to small changes of the selected region, so that clustering results can be misleading and bias subsequent analyses. In this article, we — a team of visualization scientists and meteorologists-deliver visual analytics solutions to analyze the sensitivity of clustering results with respect to changes of a selected region. We propose an interactive visual interface that enab…
Task-based visual analytics for interactive multiobjective optimization
2020
We study how visual interaction techniques considered in visual analytics can be utilized when implementing interactive multiobjective optimization methods, where a decision maker iteratively participates in the solution process. We want to benefit from previous research and avoid re-inventing ideas. Our aim is to widen awareness and increase the applicability of interactive methods for solving real-world problems. As a concrete approach, we introduce seven high-level tasks that are relevant for interactive methods. These high-level tasks are based on low-level tasks proposed in the visual analytics literature. In addition, we give an example on how the high-level tasks can be implemented a…
Discovering the Discriminating Power in Patient Test Features Using Visual Analytics: A Case Study in Parkinson’s Disease
2016
Part 11: New Methods and Tools for Big Data Wokshop (MT4BD); International audience; This paper presents a novel methodology for selecting the most representative features for identifying the presence of the Parkinson’s Disease (PD). The proposed methodology is based on interactive visual analytic based on multi-objective optimisation. The implemented tool processes and visualises the information extracted via performing a typical line-tracking test using a tablet device. Such output information includes several modalities, such as position, velocity, dynamics, etc. Preliminary results depict that the implemented visual analytics technique has a very high potential in discriminating the PD …
Geo-visual analytics for urban design in the context of future Internet
2009
The internet, where much of the information has reference to location, together with the latest generation of geographical web services, represent a very large information space that can be used for planning and design. The wealth of information accessible, which requires new forms of interaction and management of the data available, has brought in recent year to the growth of the domain of visual analytics. In addition, the availability of 3D geobrowsers provides the technological means for interactive 3D environments which can be used to access large-scale geographical information. This technological scenario is paving the way to 3D web-based, geo-visual analytics tools for land planning …
Web accessibility for visual disabled: An expert evaluation of the Inclusite® solution
2012
This study analyzes web accessibility problems for people with visual disability and presents the results of testing a prototype of Inclusite® system, an access solution designed to facilitate web navigation for people with visual disability, consisting of a navigation interface through keyboard and speech synthesis. An expert typhlotechnologist conducts a navigation test in three sessions evaluating the prototype positively and suggesting aspects for improvement. The interface provides web access as a service, the access solution is hosted in the website, so that the user can perform navigation using a different computer (not the own) which does not have his usual technical aids, helping t…
