El desarrollo de la atención selectiva y modos de percepción holísticos y analíticos

Resumen

Se analiza el desarrollo de la percepción de la estructura dimensional de estímulos hidimensionales en términos de la integralidad-separabilidad de las dimensiones y las consecuencias que para los estudios sobre el desarrollo de la atención selectiva tiene el desarrollo de la percepción desde modos holisticos a modos analíticos. Se concluye que para estudiar el desarrollo de la atención selectiva es necesario tener en cuenta la naturaleza del estímulo, en función de su estructura dimensional, y sus potenciales efectos diferenciales sobre la estructura percibida por sujetos de diferentes niveles de desarrollo, y ello en relación con las opciones de procesamiento que posibiliten diferentes estructuras percibidas.     

Creating a space for global dialogue on knowledge democracy: experiences from the inaugural global assembly for knowledge democracy

ABSTRACT

This study employed phenomenological and semi-structured interviews as an action research approach, to explore participants’ experiences around the Global Assembly for Knowledge Democracy (The Assembly) following the Conference of the Action Research Network of the Americas in Cartagena, Colombia. We sought to promote the inclusion of the diverse voices from the Global North and South who convened in the event, by understanding the participants’ experiences as part of this assembly, and its possible impact after the event. We found that Assembly participants’ experiences helped us understand Global North-South critical dialogues that challenge traditional notions of knowledge democracy that have held back, maybe unintentionally, the voices of those in the Global South. The Assembly participants’ promoted critical dialogues when presenting their visual metaphors, dances and other ways of producing knowledge during the Assembly. Although, Global North and South participants struggled with language barriers, they found enabling spaces at the Assembly to share their proposals, at both individual and community levels, framing actions and building partnerships with organizations within collective international efforts. Further, having a research team comprising both Global North and Global South voices, gave greater vision and authenticity to recognize and appreciate alternative methodologies of participation, which reconfigured the Global Assembly for Knowledge Democracy process.     

Technology push and demand pull perspectives in innovation studies: Current findings and future research directions

This study updates the debate on the sources of innovation. Using techniques like factor analysis, multidimensional scaling, and pathfinder analysis, we examine the most influential articles that have dealt with the topic. Our analysis provides three main findings. The first more precisely highlights the role of demand as a source of innovation. The second illustrates how competences enable firms to match technology with demand and capitalize on technology and demand as sources of innovation. The third unveils a distinction between external and internal sources of innovations. The sources of innovation can be purely external or internally generated competences that enable the firm to integrate external knowledge within its boundaries. Our work contributes to the classic debate by providing a more granular understanding of how technology and demand interact. In discussing our findings, we link our framework to strategy, innovation and entrepreneurship studies that expressly call for a better understanding of technology and demand factors in value creation and capture.     

Relevance of the SFU ReviewSP-NEG corpus annotated with the scope of negation for supervised polarity classification in Spanish

Up to now, negation is a challenging problem in the context of Sentiment Analysis. The study of negation implies the correct identification of negation markers, the scope and the interpretation of how negation affects the words that are within it, that is, whether it modifies their meaning or not and if so, whether it reverses, reduces or increments their polarity value. In addition, if we are interested in managing reviews in languages other than English, the issue becomes even more problematic due to the lack of resources. The present work shows the validity of the SFU Review_SP-NEG corpus, which we annotated at negation level, for training supervised polarity classification systems in Spanish. The assessment has involved the comparison of different supervised models. The results achieved show the validity of the corpus and allow us to state that the annotation of how negation affects the words that are within its scope is important. Therefore, we propose to add a new phase to tackle negation in polarity classification systems (phase iii): i) identification of negation cues, ii) determination of the scope of negation, iii) identification of how negation affects the words that are within its scope, and iv) polarity classification taking into account negation.     

Some Light on the Jumping Event in the Ancient Olympic Games: Suggestions Provided by the Purchena Games of 1569

In 1569 in the Spanish village of Purchena, a games was held in which a contingent of Turkish soldiers took part – many of them natives from the area that in antiquity was called Greece. These Turks celebrated several events in these games typical of the land of their birth. One of these events was the triple jump.

In this article we study the possibility that the jump celebrated by those Turks of the sixteenth century was the same jump that was practised in that part of the eastern Mediterranean during the time of the ancient Olympic games.

Eclairages sur les rencontres de sauts dans les Jeux Olympiques Antiques: suggestions fournies par les Jeux Purchena de 1569

En 1569 dans le village espagnol de Purchena, des jeux ont été tenus dans lesquels un contingent de soldats turcs a participé, dont beaucoup provenant d'une région que l'on appelait dans l'Antiquité la Grèce. Ces Turcs ont célébré plusieurs épreuves dans ces jeux typiques de leur terre d'origine. L'un était le triple-saut.

Dans cet article nous étudions la possibilité que le saut célébré par ces Turcs du 16ème siècle fut le même que celui qui a été pratiqué dans cette partie de la Méditerranée orientale pendant le temps des jeux Olympiques antiques.

Algunos datos sobre el salto de longitud en los Juegos Olímpicos de la Antigüedad: pistas proporcionadas por los Juegos de Purchena de 1569

En 1569 tuvieron lugar unos juegos deportivos en la ciudad española de Purchena. En ellos tomó parte un contingente de soldados turcos, muchos de ellos originarios de la región denominada Grecia en la Antigüedad. En los mencionados juegos estos turcos celebraron varias competiciones típicas de su tierra. Una de estas competiciones fue el triple salto.

En este artículo estudiamos la posibilidad de que la competición de salto celebrada por aquellos turcos del siglo XVI fuera la misma que se practicaba en esa parte del mediterráneo oriental en los tiempos de los Juegos Olímpicos de la antigüedad.

Neues zum Sprung bei den antiken Olympischen Spielen: Anregungen von den Spielen von Purchena im Jahr 1569

1569 wurden im spanischen Dorf Purchena Spiele veranstaltet, an denen ein Aufgebot von türkischen Soldaten teilnahm, von denen viele ursprünglich aus der Gegend kamen, die in der Antike Griechenland genannt wurde. Diese Türken veranstalteten verschiedene Wettbewerbe bei diesen Spielen, die für ihr Geburtsland typisch waren. Einer dieser Wettbewerbe war der Dreisprung.

In diesem Artikel wird die Möglichkeit erörtert, ob der von den Türken veranstaltete Sprungwettbewerb des 16. Jahrhunderts der gleiche war wie der, der in diesem Teil des östlichen Mittelmeerraums zur Zeit der antiken Olympischen Spiele stattfand.

     

Is there life beyond neoliberalism? Critical socio-educational alternatives for civic construction

How far does the neoliberal system pervade social and educational fields in its attempt to colonise the world of life? Neoliberalism is increasingly penetrating every aspect of human existence. From this context, this paper presents a set of alternative socio-educational experiences which are subtly constructing new latent revolutionary subjectivities. Critical educators, as transformative intellectuals, should use this crisis as an opportunity to social transformation by joining theory and praxis. Many people are now building ways of dialogic learning, new social relationships, commitment and collaborative ventures. This makes citizens more aware and critical, proving them with experiences of empowerment and cooperative work.     

Nordic walking practice might improve plantar pressure distribution

Nordic walking (NW), characterized by the use of two walking poles, is becoming increasingly popular (Morgulec-Adamowicz, Marszalek, & Jagustyn, 2011). We studied walking pressure patterns of 20 experienced and 30 beginner Nordic walkers. Plantar pressures from nine foot zones were measured during trials performed at two walking speeds (preferred and 20% faster), and under two walking conditions (NW vs. normal walking). In comparison to normal walking, NW experience led to a significant (p < .05) pressure reduction of about 50% on the central metatarsals. No significant increases were detected in other foot regions. The differences between experienced and beginners during normal walking including a 40% pressure reduction on the metatarsal area, suggests that regular NW practice might also have a beneficial effect on plantar pressure when walking without poles.     

Leadership,an essential requirement for effecting change in media companies: An analysis of the Spanish market

Abstract

As afield of study, company leadership can be examined from many angles. In this paper our aim is to study leadership in the way it effects change. The qualitative value of the information compiled is considerable since it helps to understand the grounds on which the success of the directors who effected change of the Spanish media market was based. The interviews afford us a closer look at the minds of the leading players in action.

The cases analysed show that, in media companies, radical transformations do not come about without the existence of one or several leaders, capable of mobilising the organisation where they work.

Through the literature review, the companies'internal documentation and interviews with the directors we have been able to demonstrate that our hypotheses on leadership are not only reasonable but also help to explain, to a great extent, the profound transformations which the Spanish media market has undergone in the last 25 years.
