In this article, we aim to evaluate the role of robots’ personality-driven behavioural patterns on users’ intention to use in an entertainment scenario. Toward such a goal, we designed two personalities: one introverted with an empathic and self-comparative interaction style, and the other extroverted with a provocative and other-comparative interaction style. To evaluate the proposed technology acceptance model, we conducted an experiment (N = 209) at a public venue where users were requested to play a game with the support of (...) the TIAGo robot. Our findings show that the robot personality affects the acceptance model and three relevant drivers: perceived enjoyment, perceived usefulness, and social influence. The extroverted robot was perceived as more useful than the introverted, and participants who interacted with it were faster at solving the game. On the other hand, the introverted robot was perceived as more enjoyable but less useful than the extroverted, and participants who interacted with it made fewer mistakes. Taken together, these findings support the importance of designing proper robot personalities in influencing users’ acceptance, featuring that a given style can elicit a different driver of acceptance.

Tras la conquista castellana de Córdoba, en 1236, la nueva parroquia de San Nicolás de la Ajerquía aprovechó como iglesia una pequeña mezquita junto al río Guadalquivir. El edificio, ampliado a mitad del siglo XVI y reiteradamente transformado a lo largo del tiempo, mantuvo la preexistencia islámica hasta las importantes reformas del período 1725-27, que supusieron su total demolición. Pese a que existen varias alusiones documentales de aquellos años y un dibujo a mano alzada de la planta conservado en el (...) archivo parroquial, esta mezquita ha pasado prácticamente inadvertida en la historiografía especializada, quizás porque los escasos y ambiguos datos conocidos no permiten estimar su arquitectura. En este trabajo se analiza directamente el dibujo original, contextualizándolo con distintos planos y documentos históricos. Esto ha permitido formular una hipótesis sobre las dimensiones de la sala de oración de la mezquita, su orientación aproximada, así como sobre su conformación arquitectónica interior: una planta prácticamente cuadrada, organizada en nueve ámbitos con cierta autonomía espacial y cubiertos con bóvedas. Seguiría en esto a un tipo de mezquita hace tiempo detectada por Creswell, que la denominó «nine-dome-mosque», y de la que sería el único ejemplo conocido en Córdoba. (shrink)

This study aimed to investigate the student-athletes' capability to face the academic, sport, and social challenges during the coronavirus disease 2019 (COVID-19) lockdown and to disclose novel aspects of dual careers. A 32-item online survey encompassing demographic characteristics, sport and university engagement, support and dual-career benefits, physical activity, sitting time, and the time deemed necessary to recover the previous level of performance was developed. Four hundred sixty-seven student-athletes (males: 57%, females: 43%) from 11 countries, competing in 49 different sports (individual: (...) 63.4%, team: 36.6%) at regional (17.5%), national (43.3%), and international (39.2%) levels, and enrolled at high school (21.9%) and university (78.1%) levels completed the survey. During the lockdown, the respondents decreased the time dedicated to sport and academics, although they maintained an active lifestyle. Student-athletes from countries under severe contagion were more likely to train at home, dedicate to academics, and receive support from the coach but less likely receive support from their teachers. With respect to their team sport counterparts, athletes competing in individual sports trained more and were more likely to receive support from their coaches. International athletes showed the highest training time and support from their coaches and as student-athletes. High school students received more support from their coaches and teachers, whereas university students were more likely considering dual careers useful to cope with the COVID-19 pandemic. This study substantiates the relevant role of competitive sports participation in the maintenance of active lifestyles, with student-athletes considering home training and e-learning valuable resources during the lockdown. Furthermore, their sport and academic commitments helped student-athletes cope with the emergency of the COVID-19 pandemic. (shrink)

A growing number of recreational races are being held in different locations, drawing many local and visiting runners. This study examined the relationships between quality, value, satisfaction, and loyalty among runners in a recreational race and examines potential differences in relationships between these constructs based on the runners’ experience. The participants were 985 runners with a mean age of 40.74±9.41years. Validated, reliable ad hoc instruments were used. A multi-group analysis was performed to ascertain the existence of relationships between the constructs (...) and differences in the relationships between the different study groups. The results show that quality is a direct antecedent of value and satisfaction. Value is directly related to satisfaction and indirectly related to loyalty. Satisfaction is related to the loyalty of participants in the race. Differences in the relationship between satisfaction and loyalty were dependent upon the runners’ experience. Loyalty to a race depends primarily on satisfaction and is modified by the runners’ experience. (shrink)

The DNA‐passage activity of topoisomerase II accidentally produces DNA knots and interlinks within and between chromatin fibers. Fortunately, these unwanted DNA entanglements are actively removed by some mechanism. Here we present an outline on DNA knot formation and discuss recent studies that have investigated how intracellular DNA knots are removed. First, although topoisomerase II is able to minimize DNA entanglements in vitro to below equilibrium values, it is unclear whether such capacity performs equally in vivo in chromatinized DNA. Second, DNA (...) supercoiling could bias topoisomerase II to untangle the DNA. However, experimental evidence indicates that transcriptional supercoiling of intracellular DNA boosts knot formation. Last, cohesin and condensin could tighten DNA entanglements via DNA loop extrusion (LE) and force their dissolution by topoisomerase II. Recent observations indicate that condensin activity promotes the removal of DNA knots during interphase and mitosis. This activity might facilitate the spatial organization and dynamics of chromatin. (shrink)

Playing traditional games has a direct impact on the mood states of the players, and this is the reason why physical education is an ideal setting for teaching how to recognize them and be aware about how they can swing. The objective of the study was to determine if participating in traditional opposition games causes changes to the participants' mood states. A total of 102 students participated. Each participant recorded the intensity of the mood state experienced at the beginning and (...) at the end of the sessions, using the validated Profile of Mood States instrument. The pedagogical experience was planned as 4 sessions with 6 and 5 opposition games each: with competition in mixed groups, equally and unequally mixed; without competition in mixed groups, equally and unequally mixed; with competition in same-gender groups; and without competition in same-gender groups. When comparing the different mood states according to session, the mood states of the depression, fatigue, and vigor dimensions were significantly different, with higher scores in the sessions with competition for the mood states of vigor and fatigue. Also, when comparing the mood states depending on session grouping and group type, the results showed differences in the scores obtained for the dimensions fatigue and anger, and general mood state. These differences were found at the start of the session and at the end, with the dimension fatigue being the only one with differences in both situations when comparing the same-gender, equally-mixed, and unequally-mixed groups for the two types of traditional opposition games compared. In addition, after an analysis of the mood states depending on gender was performed, the results and therefore the significant differences found, were very similar to those obtained according to group type. Lastly, it was concluded that the type of group, and gender were decisive, causing variations in the mood states of the students. This provides valuable information for teaching professionals about the structuring and organization of PE sessions, aiming to promoting positive motor experiences. (shrink)

The introduction of a new analytical method, due fundamentally to François Viète and René Descartes and the later dissemination of their works, resulted in a profound change in the way of thinking and doing mathematics. This change, known as process of algebrization, occurred during the seventeenth and early eighteenth centuries and led to a great transformation in mathematics. Among many other consequences, this process gave rise to the treatment of the results in the classic treatises with the new analytical method, (...) which allowed new visions of such treatises and the obtaining of new results. Among those treatises is the Arithmetic of Diophantus of Alexandria which was written, using the new algebraic language, by the French mathematician Jacques Ozanam, who in addition to profusely increasing the original problems of Diophantus, solved them in a general way, thus obtaining many geometric consequences. The work is handwritten, it has never been published, it has been lost for almost 300 years, and the known references show its importance. We will show that Ozanam’s manuscript was quoted as an important work on several occasions by others mathematicians of the time, among whom G. W. Leibniz stands out. Once the manuscript has been located, our aim in this article is to show and analyze this work of Ozanam, its content, its notation and its structure and how, through the new algebraic method, he not only solved and expanded the questions proposed by Diophantus, but also introduced a connection between the algebraic solutions and what he called geometric determinations by obtaining loci from the solutions.

Neste artigo pretende-se discutir a dimensão política presente na origem da teoria do reconhecimento de Axel Honneth, partindo da constatação de que durante a reelaboração de sua tese de habilitação, publicada em 1992 com o título de Luta por reconhecimento, o autor se posiciona pela primeira vez diante do debate entre liberais e comunitaristas e elabora seu conceito formal de eticidade como uma resposta às limitações de cada uma dessas correntes da teoria política contemporânea.

This article examines the relationships between gender and technology in Spanish feminist praxis online and argues that different perspectives on online feminist community-building offer distinct responses to cyberactivism, which is considered central to sustaining efforts for social change. To ascertain whether Spanish virtual communities and cyberactivism have the potential to address the challenges posed by the relations between gender and technology, we analyse feminist scholar Remedios Zafra's theoretical proposals, and the different ways in which this theory intersects with the cyberactivism (...) put forth by two feminist web portals, Ciudad de Mujeres and Mujeres en Red. We will discuss to what degree particular Spanish feminist theory and practice online adapts to or challenges utopianism regarding the liberating potential of technology. We will also examine how, in the face of critical arguments about such liberatory possibilities, two options present themselves for women's effective use of technology: inhabiting or occupying the web through the construction of feminist communities online.

This chapter discusses the question of whether we will ever have an Artificial General Superintelligence (AGSI) and how it will affect our species if it does so. First, it explores various proposed definitions of AGSI and the potential implications of its emergence, including the possibility of collaboration or conflict with humans, its impact on our daily lives, and its potential for increased creativity and wisdom. The concept of the Singularity, which refers to the hypothetical future emergence of superintelligent machines that (...) will take control of the world, is also introduced and discussed, along with criticisms of this concept. Second, it is considered the possibility of mind uploading (MU) and whether such MU would be a suitable means to achieve (true) immortality in this world—the ultimate goal of the proponents of this approach. It is argued that the technological possibility of achieving something like this is very remote, and that, even if it were ever achieved, serious problems would remain, such as the preservation of personal identity. Third, the chapter concludes arguing that the future we create will depend largely on how well we manage the development of AI. It is essential to develop governance of AI to ensure that critical decisions are not left in the hands of automated decision systems or those who create them. The importance of such governance lies not only in avoiding the dystopian scenarios of a future AGSI but also in ensuring that AI is developed in a way that benefits humanity. (shrink)

En el presente artí- culo abordamos la situación sociohistórica subyacente a 1 Clemente y basándonos en los estudios socioló- gicos sobre 1 Cor, en particular los de G. Theissen, demostramos cómo 1 Clem. 3, 3 describe el conflicto de Corinto en categorías esencialmente socio-económicas, considerando que el motivo que propició la revuelta obedece básicamente al enfrentamiento entre grupos de distinto estatus para alcanzar el liderazgo y evitar la vergüenza. Ello indica que Clemente presenta el conflicto como una lucha de poder (...) para conseguir el prestigio social, en un mundo estrechamente marcado por la cultura del honor y la institución del patronazgo.

Se revisan las noticias que la prensa nacional publicó durante la inauguración del Museo Nacional de Antropología en 1964, y se exploran otras noticias de naturaleza semejante, como la inauguración del Museo Nacional del Virreinato de Tepotzotlán y el Museo de Arte Moderno, al tiempo que se reflexiona sobre la identidad nacional, el patrimonio y el papel del museo en la sociedad y la cultura mexicana.

Empirical research on the effect of religion on attitudes toward the environment remains divided into two opposing points of view, which claim a positive or negative effect on pro-environmental attitudes. This study analyses these relationships in a Spanish sample from a multidimensional perspective. The results of this study show, this time in a European context, the negative relationship between religious literalism and concern for the environment previously found in studies based on American samples. They also show the negative influence of (...) specific aspects of expressions of Judaeo-Christian religiosity, especially the rigidity characteristic of some non-traditional dimensions of religiosity, which arguably can be present without the co-presence of biblical literalism, and also the positive effect of quest-oriented religiosity and approaches focusing on existential well-being. The unique contributions of these variables in explaining concern for the environment are mapped to specific variances in the outcome variables. (shrink)
