Young generation and accessibility to health dissemination: TikTok as a case study.
2022
Social media interactions represent an accessible way for young people to get health information and provide a form of public discourse about health. It is against this backdrop that experts and other health professionals have turned to digital platforms (e.g., TikTok) to share educational content about timely or touchy topics, and to spread awareness, specifically among younger users. This paper aims to explore these digital platforms where professionals provide health information that is specifically tailored for a young audience and attempts to explore the discursive negotiation of healthcare and health accessibility in digital social settings. In light of a social media critical discour…
Semantically-enhanced advertisement recommender systems in social networks
2017
El objetivo principal de la investigación es estudiar y diseñar un entorno de recomendación publicitaria en las redes sociales que puede ser enriquecido mediante tecnologías semánticas. A pesar de que existen muchas aplicaciones y soluciones para los sistemas de recomendación, en este estudio se diseña un framework robusto con un rendimiento adecuado para poder ser implementado en las redes sociales con el objetivo de ampliar los propósitos de negocio. De este objetivo principal se pueden derivar los siguientes objetivos secundarios: 1. Superar las limitaciones iniciales de los métodos clásicos de recomendación. 2. Aumentar la calidad y precisión de las recomendaciones y el rendimiento del …
A Deep Learning Model for Automatic Sleep Scoring using Multimodality Time Series
2021
Sleep scoring is a fundamental but time-consuming process in any sleep laboratory. Automatic sleep scoring is crucial and urgent to help address the increasing unmet need for sleep research. Therefore, this paper aims to develop an end-to-end deep learning architecture using raw polysomnographic recordings to automate sleep scoring. The proposed model adopts two-dimensional convolutional neural networks (2D-CNN) to automatically learn features from multi-modality signals, together with a "squeeze and excitation" block for recalibrating channel-wise feature responses. The learnt representations are finally fed to a softmax classifier to generate predictions for each sleep stage. The model pe…
Skills Behind the Robotics : How to Re-educate Workers for the Future
2019
The aim of this study is to respond to the educational needs of the future, considering automation and robotics. It is inevitable that automation and robotics are changing our lives and they create challenges for the future work life and education. In this study, we investigate what is the educational background of the unemployed people who are in danger of being replaced by automation and what is their educational resilience for adapting work life changes. The data of this study consist of the latest PIAAC data (The Programme for the International Assessment of Adult Competencies). Based on the research we develop a model for re-educating the people who have lost their jobs. peerReviewed
Hyvää verkko-opetusta etsimässä: oppimista edistävät ja estävät tekijät verkko-oppimisympäristöissä – opiskelijoiden kokemuksen ja opettajien arviot
2003
Tutkimuksen tarkoituksena oli selvittää opiskelijoiden ja opettajien käsityksiä hyvästä verkko-opetuksesta ja -opiskelusta. Tutkimuksessa keskityttiin erityisesti verkko- opettajan roolin ja tehtävien tarkasteluun. Verkko-opetusta tutkittiin osana opetus-opiskelu-oppiminen prosessia (Uljens 1997, Kansanen 1999). Hyvän verkko-opettajan ominaisuuksia etsittiin tehokkaan opettajan kriteerien (Tirri 1993), opettajan pedagogisen ajattelun ja verkko-opettajatutkimuksien lähtökohdista käsin. Mielekäs oppiminen määriteltiin Jonassenin (1995) esittämien kriteerien lähtökohdista. Tutkimuksen empiirinen aineisto koostui vuosina 1995-1999 Helsingin yliopiston virtuaalisen avoimen yliopiston (HEVI) ja A…
Statistical Regularities in ATM: network properties, trajectory deviations and delays
2012
One of the key enabler to the productivity and efficiency shift foreseen by SESAR will be the business-trajectory concept. The path to a deep understanding of how this new concept impacts on the future SESAR Air Traffic Management scenario goes through a better understanding of the actual air traffic network, and this will be done in the present paper by analyzing traffic data within the framework of complex network analysis. In this paper we will consider flights trajectory data from the Data Demand Repository database. In a first investigation, we perform a network study of the air traffic infrastructure starting from the airports and then refining our analysis at the level of navigation …
ELSA Project: Toward a complex network approach to ATM delays analysis
2011
The paper presents the preliminary results delivered by the WPE project ELSA. After some introductory notes about the project aims and structure, the paper shows how tools borrowed by the Complex Network Theory can be used to study the issue of delays in the air traffic system.
Analysis of the Structure and Dynamics of European Flight Networks
2022
We analyze structure and dynamics of flight networks of 50 airlines active in the European airspace in 2017. Our analysis shows that the concentration of the degree of nodes of different flight networks of airlines is markedly heterogeneous among airlines reflecting heterogeneity of the airline business models. We obtain an unsupervised classification of airlines by performing a hierarchical clustering that uses a correlation coefficient computed between the average occurrence profiles of 4-motifs of airline networks as similarity measure. The hierarchical tree is highly informative with respect to properties of the different airlines (for example, the number of main hubs, airline participa…
Aviokompāniju reklāmu raksturojums sociālo tīklu tīmekļa vietnēs Facebook un Twitter
2018
Reklāma ir profesionālā diskursa žanrs, kas tiek izmantots komunikācijai ar sabiedrību. Mūsdienās internets un sociālo tīklu tīmekļa vietnes tiek bieži izmantotas reklāmas nolūkos. Šī pētījuma mērķis bija analizēt lingvistiskās un paralingvistiskās iezīmes sociālo tīklu tīmekļa vietnēs Facebook un Twitter publicētajās aviokompāniju reklāmās. Pētījums tika balstīts uz Kuka (Cook, 1992) piedāvāto diskursa analīzes modeli, kas ietver teksta un konteksta analīzi. Pētījuma rezultāti parādīja, ka šo reklāmu tekstos izmantotā valoda ir vienkārša un lasītājam draudzīga, kas ir panākts, pārsvarā izmantojot vienkāršus teikumus, kā arī lietojot kontrakcijas un saīsinājumus. Tā arī imitē sarunu ar lasī…
The Route Development Strategies of Romanian Airports: A Key Challenge in Modern Aviation
2018
Airport route development can be defined as a complex process carried out by airports, encouraging airlines to launch new routes or increase frequencies on already served destinations. The deregulated aviation environment helped airports to find new and innovative ways to compete directly with each other for a limited airline capacity, engaging with airlines and proving the airport route development strategy and airline needs meet at a certain point. The future prosperity of the communities the airports serve, depends on the efforts of the route development team and their focused aviation marketing strategy. A huge responsibility to attract what is best for the community as well as a good c…
