Brain activity in the action observation network is lateralized during action execution, with greater activation in the contralateral hemisphere to the side of the body used to perform the task. However, it is unknown whether the AON is also lateralized when watching another person perform an action. In this study, we use fNIRS to measure brain activity over the left and right cortex while participants completed actions with their left and right hands and watched an actor complete action with their (...) left and right hands. We show that while activation is lateralized when the participants themselves are moving, brain lateralization is not affected by the side of the body when the participant is observing another person’s action. In addition, we demonstrate that individual differences in hand preference and dexterity between the right and left hands are related to brain lateralization patterns. (shrink)

This article examines the role of social media and journalistic media in presidential electoral processes. A systematic review of scientific articles published from 2012 to 2022 was conducted. The results indicate that the media has a significant influence on public perception and the political agenda during election campaigns. Furthermore, the importance of evaluating political leaders in the voters' decision-making process is emphasized. In summary, the article provides valuable insights into how the media can shape the narrative and public opinion during (...) presidential elections. (shrink)

El artículo estudia la refutación del origenismo evagriano que lleva a cabo Máximo el Confesor en el Ambiguum 7, donde esta crítica está tematizada con mayor claridad. Máximo invierte la tríada origenista estabilidad-movimiento-creación, defendiendo con ello que las almas no preexisten a la creación, sino que lo que precede es la voluntad de Dios para con los seres creados, y que el cuerpo y el alma fueron creados simultáneamente.

An extension of the Quantified Propositional Calculus1 obtained by the addition of two binary propositional functions is put forward as an inheritor of E. Schröder's “Algebra der Logik”. The formal system is itself not new, in fact it forms part of A. P. Morse's “A Theory of Sets”; although the latter is considered as a first-order system. Since the additional propositional functions are not invariant under the logical biconditional, this system–and many others naturally obtained from it–give us a collection of (...) examples of non-standard, but mathematically meaningful, propositional systems.

A conservative extension of first order logic, suitable for circumscriptive inference, is introduced.

A reduction algebra is defined as a set with a collection of partial unary functions (called reduction operators). Motivated by the lambda calculus, the Church-Rosser property is defined for a reduction algebra and a characterization is given for those reduction algebras satisfying CRP and having a measure respecting the reductions. The characterization is used to give (with 20/20 hindsight) a more direct proof of the strong normalization theorem for the impredicative second order intuitionistic propositional calculus.

PurposeThe purpose of this paper is to present a case study of the creation of a Knowledge Zone in Curaçao to provide an insight into how a Knowledge Zone is established. After devising a vision, strategic alliances were formed. This created synergy and momentum, giving the project and process a life of their own.Design/methodology/approachThe project of creating a K‐Zone is based on a theoretical framework which draws upon the notion of a creative class, and how it can be attracted to (...) a specific location. It also deploys change management methodology, which describes how change is implemented. The theory states that creativity will drive the economy in the future and that societies that are able to attract the creative class will excel. It is not clear what attracts the creative class but it is believed that a certain life style, concentrations of peers and virtual and physical connectivity are essential. To create these conditions some changes must be implemented and these changes are often resisted in the beginning.FindingsKnowledge Zones can be created if there is a clear shared vision, leadership and alliances that forge synergies. The project was started in 2010 by the UNA under the presidency of Dr Miguel Goede, the Rector Magnificus of the University of the Netherlands Antilles. With the support of the Board of Supervisors, the UNA entered/sought alliances with the nearby Carmabi Research Institute and the neighbouring school for nurses, which opened a new school building within the designated zone. The UNA also provided the impetus to start a campaign to construct a new hospital that was planned for the area neighbouring the university and to start a school of medicine. But the breakthrough came when the local telecom provider, United Telecommunication Services, decided to provide the university with dedicated internet connections that were capable of the highest speed available on the island.Originality/valueThe paper contributes to a framework for understanding the creative economy of Small Islands Developing States in the Caribbean and how change can be implemented in these settings.

Computer vision research involving street and road detection methods usually focuses on driving assistance and autonomous vehicle systems. In this context, street segmentation occurs in real-time, based on images centered on the street. This work, on the other hand, uses street segmentation for urban planning research to classify pavement types of a city or region, which is particularly important for developing countries. For this application, it is needed a dataset with images from various locations for each street. These images are (...) not necessarily centered on the street and include challenges that are not common in street segmentation datasets, such as mixed pavement types and the presence of faults and holes on the street. We implemented a multi-class version of a state-of-the-art segmentation algorithm and adapted it to perform street pavement classification, handling navigation along streets and angle variation to increase the accuracy of the classification. A data augmentation approach is also proposed to use preliminary results from the test instances as new ground truth and increase the amount of training data. A dataset with more than 300,000 images from 773 streets from a Brazilian city was built. Our approach achieved a precision of 0.93, showing the feasibility of the proposed application. (shrink)
