El Prácticum de Ciencias Sociales en dos Universidades Iberoamericanas
2019
El artículo presenta un estudio comparativo de algunas de las percepciones que tienen futuros docentes de la Universitat de Valencia (Valencia-España) y Francisco José de Caldas (Bogotá-Colombia) sobre su desempeño docente. Las fuentes utilizadas para su análisis han sido los informes de las prácticas elaborados finalizada su intervención de aula. El trabajo se realiza desde una perspectiva cualitativa acudiendo al estudio de caso, que permite comprender un fenómeno de manera detallada. La formación inicial de profesores en didáctica de las ciencias sociales se ve influenciada por sus percepciones, que manifiestan diferencias entre las prácticas de aula y las teorías que se proponen en las …
Maintaining information in Short-Term Memory between 2 and 6 years old of age : temporal forgetting and helping in maintaining the goal
2014
Working memory is an essential component of thought that is highly involved in learning and academic achievement. However, it is rarely studied in preschoolers, mainly because of a lack of suitable paradigms. Therefore, this thesis investigated the functioning of working memory in children between 2 and 6 years. For this purpose, two original paradigms were used. They were designed to be close to game situations which should help young children to focus their attention on the task. Firstly it was shown that the recall performance decreased over time, even in the absence of an interfering task. Children of this age therefore use a passive maintenance, i.e. without spontaneously implementing …
Copy–Move Forgery Detection by Matching Triangles of Keypoints
2015
Copy-move forgery is one of the most common types of tampering for digital images. Detection methods generally use block-matching approaches, which first divide the image into overlapping blocks and then extract and compare features to find similar ones, or point-based approaches, in which relevant keypoints are extracted and matched to each other to find similar areas. In this paper, we present a very novel hybrid approach, which compares triangles rather than blocks, or single points. Interest points are extracted from the image, and objects are modeled as a set of connected triangles built onto these points. Triangles are matched according to their shapes (inner angles), their content (c…
A tool to support the creation of datasets of tampered videos
2015
Digital Video Forensics is getting a growing interest from the Multimedia research community, as the need for methods to validate the authenticity of a video content is increasing with the number of videos freely available to the digital users. Unlike Digital Image Forensics, to our knowledge, there are not standard datasets to test video forgery detection techniques. In this paper we present a new tool to support the users in creating datasets of tampered videos. We furthermore present our own dataset and we discuss some remarks about how to create forgeries difficult to be detected by an observer, to the naked eye.
State of the art in passive digital image forgery detection: copy-move image forgery
2017
Authenticating digital images is increasingly becoming important because digital images carry important information and due to their use in different areas such as courts of law as essential pieces of evidence. Nowadays, authenticating digital images is difficult because manipulating them has become easy as a result of powerful image processing software and human knowledge. The importance and relevance of digital image forensics has attracted various researchers to establish different techniques for detection in image forensics. The core category of image forensics is passive image forgery detection. One of the most important passive forgeries that affect the originality of the image is cop…
Oblio, Identità e verità (Parte prima)
2022
Può esistere un diritto a dimenticare a fronte di indiscutibile diritto a ricordare, senza che si consegni alle Corti il potere di riscrivere la storia, eliminando frammenti della sua memo ria? È attorno tale interrogativo che si snodano le riflessioni dell’autore, dirette ad accertare l’esistenza e la natura di un diritto all’oblio, inteso come diritto ad essere dimenticati. La ri voluzione digitale ha consentito la creazione di un archivio infinito e permanente, ma legittimo appare il dubbio circa l’opportunità di un suo indiscriminato sviluppo e di una illimitata tutela del diritto alla memoria, a fronte di istanze di tutela individuale di dignità umana. La risposta, secondo l’autore, è …
La “desconexión digital” a lomos de la seguridad y salud en el trabajo
2021
The preponderance given to teleworking or remote work due to the health crisis is pushing to blur the line that separates effective work time from leisure and rest time. In the end, it practically causes the employee to never disconnect from work. And this is so because Information and Communication Technologies (ICT) push workers to have a constant time and location availability, even outside their working hours. In this sense, communications from bosses, co-workers or even clients through different means like now are not surprising: emails that need an urgent answer, phone calls at untimely hours or, especially in the sense of this article, through the smartphone, either by SMS messages -…
Grupas "Skyforger" ietekme uz nacionālās identitātes veidošanos subkultūrās
2018
Bakalaura darba “Grupas “Skyforger” ietekme uz nacionālās identitātes veidošanos subkultūrās” mērķis ir noskaidrot, vai folkmetāla/pagānmetāla grupa ir spējīga veidot tās auditorijā nacionālās identitātes sajūtu un patriotismu. Darba teorētiskajā daļā tika apskatīta šī mūzikas žanra vēsture, rašanās iemesli, tā pasniegtās vērtības un metālistu subkultūras vēsture un vērtības. Darba empīriskās daļas datu ievākšanai izmantota daļēji strukturēta intervija ar grupas līderi, fokusgrupas diskusija ar metālistu subkultūras pārstāvjiem un aptauja. Darba rezultātos secināts, ka grupas “Skyforger” mūzika tiešā veidā nerada patriotisma un nacionālās identitātes izjūtu tās auditorijā, bet liek lepoties…
On the impact of forgetting on learning machines
1995
People tend not to have perfect memories when it comes to learning, or to anything else for that matter. Most formal studies of learning, however, assume a perfect memory. Some approaches have restricted the number of items that could be retained. We introduce a complexity theoretic accounting of memory utilization by learning machines. In our new model, memory is measured in bits as a function of the size of the input. There is a hierarchy of learnability based on increasing memory allotment. The lower bound results are proved using an unusual combination of pumping and mutual recursion theorem arguments. For technical reasons, it was necessary to consider two types of memory : long and sh…
Dos inscripciones sobre la fundación de Lara y una sobre sus siete infantes, con un análisis evolutivo de su iglesia parroquial
2016
Se someten a crítica filológica e histórica tres inscripciones epigráficas procedentes de Lara de los Infantes que abordan el discutido tema del origen de Castilla. La factura de la más antigua, encontrada en la ermita de San Julián (en el Museode Burgos desde principios del siglo XX) se debió de redactar a mediados del siglo XII, en sintonía con el monasterio burgalés de San Pedro de Arlanza, pues resalta la preeminencia de este centro en su vínculo con Fernán González. Posiblemente se basó también en una tradición local lareña hoy perdida y, en todo caso, partiendo de noticias espurias. En época humanística, antes del año 1600, se realizó una copia de esta inscripción a la que se añadió o…
