Background: Despite the reported harms and ethical concerns about physical restraint use in the critical care settings, nurses’ intention to apply them is unequal across countries. According to the theory of planned behaviour, eliciting nurses’ beliefs regarding the use of physical restraints would provide additional social information about nurses’ intention to perform this practice. Aim: To explore the salient behavioural, normative and control beliefs underlying the intention of critical care nurses to use physical restraints from the theory of planned behaviour. (...) Research design: A belief elicitation study was conducted. Participants and research context: Twenty-six critical care nurses were purposively sampled across gender, work-shift patterns and professional experience in five intensive care units of three hospitals in Spain. Data were obtained from a nine-item open-ended questionnaire and a focus group. Deductive content analysis was performed. Ethical considerations: Ethical approval was obtained from the hospital ethics committee. Participants were assured their participation was voluntary. Findings: Nurses framed the use of restraints as a way of prioritising patients’ physical safety. They referred to contextual factors as the main reasons to justify their application. Nurses perceived that their decision is approved by other colleagues and the patients’ relatives. Some nurses started advocating against their use, but felt powerless to change this unsafe practice within an unfavourable climate. Control beliefs were linked to patients’ medical condition, availability of alternative solutions, analgo-sedation policies and work organisation. Discussion: Safety arguments based on the surrounding work environment were discussed. Conclusion: Nurses’ behavioural and control beliefs were related. Nurses should be trained in alternatives to physical restraint use. The impact of analgo-sedation protocols, relatives’ involvement, leadership support and intensive care unit restraint policies on physical restraint practices need to be revised. Further research is required to explore why nurses do not act with moral courage to change this harmful practice. (shrink)

This work presents a novel approach to forecast streaming big time series based on nearest similar patterns. This approach combines a clustering algorithm with a classifier and the nearest neighbours algorithm. It presents two separate stages: offline and online. The offline phase is for training and finding the best models for clustering, classification and the nearest neighbours algorithm. The online phase is to predict big time series in real time. In the offline phase, data are divided into clusters and a (...) forecasting model based on the nearest neighbours is trained for each cluster. In addition, a classifier is trained using the cluster assignments previously generated by the clustering algorithm. In the online phase, the classifier predicts the cluster label of an instance, and the proper nearest neighbours model according to the predicted cluster label is applied to obtain the final prediction using the similar patterns. The algorithm is able to be updated incrementally for online learning from data streams. Results are reported using electricity consumption with a granularity of |$10$| minutes for 4-hour-ahead forecasting and compared with well-known online benchmark learners, showing a remarkable improvement in prediction accuracy.

Gregory Bateson is well known for defining information by stating “In fact what we mean by information – the elementary unit of information – is a difference which makes a difference…” This conceptual perspective has the merit of simplicity and generality. Simplicity, in addressing the complexity of information. Generality, in seeking applicability to any and every field of human experience. The purpose of this paper is to focus the applicability of this conceptual approach by Bateson and use it to perform (...) a calculation of taking the difference between two grey-level digital images that are shifted one relative to the other. The digital images take the place of the field of view that a human being would have access through her sense of vision at two different spatial/temporal instances. The results show that it is possible to highlight the edges of the objects under scrutiny, as well as to highlight other differences within the object. Bateson’s “difference that makes a difference” would seem to provide a first step in the elusive meaning making process of humans. (shrink)

Delusions are one of the most classical symptoms described in schizophrenia. However, despite delusions are often emotionally charged, they have been investigated using tasks involving non-affective material, such as the Beads task. In this study we compared 30 patients with schizophrenia experiencing delusions with 32 matched controls in their pattern of responses to two versions of the Beads task within a Bayesian framework. The two versions of the Beads task consisted of one emotional and one neutral, both with ratios of (...) beads of 60:40 and 80:20, considered, respectively, as the “difficult” and “easy” variants of the task. Results indicate that patients showed a greater deviation from the normative model, especially in the 60:40 ratio, suggesting that more inaccurate probability estimations are more likely to occur under uncertainty conditions. Additionally, both patients and controls showed a greater deviation in the emotional version of the task, providing evidence of a reasoning bias modulated by the content of the stimuli. Finally, a positive correlation between patients’ deviation and delusional symptomatology was found. Impairments in the 60:40 ratio with emotional content was related to the amount of disruption in life caused by delusions. These results contribute to the understanding of how cognitive mechanisms interact with characteristics of the task in the context of delusional thinking. These findings might be used to inform improved intervention programs in the domain of inferential reasoning. (shrink)

La interpretación y el texto mismo de unas líneas del parágrafo 94 del discurso Sobre la embajada fraudulenta de Demóstenes han sido objeto de discusiones, en particular la expresión τὴν πρώτην ἔφερον τοῦ φενακισμοῦ. En nuestra opinión, el problema se podría resolver si interpretamos que a lo largo de todo el pasaje se desarrolla una metáfora deportiva, en concreto relacionada con las λαμπαδηδρομίαι o carreras de relevos con antorchas. The text and the interpretation of some lines in Demosthenes' On the (...) false embassy has been discussed, particularly the expression τὴν πρώτην ἔφερον τοῦ φενακισμοῦ. In our opinion, the problem can be solved by understanding that in all the passage Demosthenes uses a sports metaphor that has to do with the λαμπαδηδρομίαι or torch relay races. (shrink)

La integración del Imperio Otomano y la progresista aparición, en su seno, de estados independientes a lo largo del siglo XIX trajo consigo la inevitable confluencia del espíritu ilustrado-romántico europeo, impulsor de las revoluciones en Europa y América, y el peso de la identidad nacional, arraigada en los esquemas patriarcales tradicionales. En ese exigente proceso de remodelación sociopolítica e ideológica, surgen discursos femeninos que, pese la escasa capacidad de maniobra, sitúan a la mujer en el epicentro del cambio y diseñan (...) una estrategia de lucha feminista.Presentamos dos discursos femeninos, los de la activista griega Kalirroe Parén (1861-1940) y la libanesa-palestina Mayy Ziyada (1866-1941), afincada en Egipto. Ambos se fundamentan en la actividad intelectual y literaria de sus creadoras, en los primeros y sólidos idearios feministas griego y árabe, y en la capacidad política de cambio de la mujer en un entorno hostil.

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 (approx. 200–284) which was written, using the new algebraic language, by the French mathematician Jacques Ozanam (1640–1718), 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.

In the 1970s and 1980s, a multitude of cognitive rehabilitation programs proliferated to facilitate recovery after brain injury. However only a few programs provided a framework for ameliorating disturbances in the cognitive, psychological, and interpersonal spheres of the brain-injured patient. Greatly influenced by Leonard Diller and Yehuda Ben-Yishay’s ideas and methods, George P. Prigatano began, in early 1980, a holistic neuropsychological rehabilitation program at the Presbyterian Hospital in Oklahoma City (Oklahoma). The objective of this paper is to summarize the contributions (...) of George P. Prigatano to neuropsychological rehabilitation and clinical neuropsychology during his 50th year of practice. The main body of the paper is structured in three sections. The first section briefly explains the history of neuropsychological rehabilitation in the twentieth century and the emergence of holistic neuropsychological rehabilitation programs in the 1970s. The second section describes the contributions of George P. Prigatano to neuropsychological rehabilitation and clinical neuropsychology (written by AGM). In the third section, the second author (GPP) prepared an autobiographical statement, which attempts to summarize some of the personal and professional experiences which influenced his work. George P. Prigatano’s contributions to neuropsychological rehabilitation and clinical neuropsychology are essential to understanding the therapeutic approaches currently used in the treatment of brain-injured patients.

This article analyzes the construction of female subjectivity in the specific context of audiovisual cyberspaces in Spain dedicated to the struggle against violence against women. Looking at the YouTube channels of two virtual feminist communities that deal with violence against women, the authors analyze how the victim-subject is configured in terms of agency and activism. The authors adopt a multimodal model of studying the sign complexes of the videos as semiotic artifacts that produce meaning. Sign complexes are always engaged because (...) representation is never neutral because what is represented in sign is meant to realize the values and positions of those who make the sign. In this article, the authors understand feminist activism in the fight against violence targeting women as constructing in its discourse not only the activist process, but also the subject of this activism: the victim-subject of gender-based violence. The analysis engages in the discussion about the various ways in which this subject is interpellated by the audiovisual texts in terms of agency. As a result, this study proposes the necessity to devise new ways of articulating this subject as a political and agential one. (shrink)

Academic entrepreneurship and the formation of spin-offs from educational institutions have been consolidated as essential elements to promote innovation and stimulate economic growth worldwide. However, the evolution of these initiatives shows marked differences between developed countries and emerging economies, such as Colombia. This study focuses on analyzing how research in this area has progressed, identifying the key factors that determine the success of spin-offs and suggesting a framework for action for Colombia in comparison with international dynamics. The findings reveal a (...) shift in research attention from prioritizing the creation of spin-offs to a greater focus on their long-term performance and sustainability. At the international level, the relevance of technology transfer, strategic alliances between universities and industry and the efficient management of technological resources are highlighted. On the other hand, in the Colombian context, research tends to focus on institutional aspects, cultural factors and support regulations, underestimating the analysis of the performance of spin-offs after their creation. This paper aims to contribute to the formulation of policies and strategies that promote not only the emergence but also the sustainability of academic spin-offs in Colombia, seeking to align their practices with international standards in order to maximize their impact on the economic and social development of the country.

Obesity is a worldwide epidemic associated with severe health and psychological wellbeing impairments expressed by an increased prevalence of affective disorders. Emotional dysfunction is important due to its effect on social performance. The aim of the present narrative review is to provide a general overview of human research exploring emotional information processing in overweight and obese people. Evidence suggests that obesity is associated with an attenuation of emotional experience, contradictory findings about emotion recognition, and scarce research about automatic emotional information (...) processing. Finally, we made some concluding considerations for future research on emotional information processing in overweight and obese people. (shrink)

The purpose of this research is to reflect on the role of the context environment of the contextualized situations of teaching school mathematics, which make significant contributions to the initial training of the mathematics teacher at the Universidad Popular del Cesar-Valledupar-Colombia, where the informants were the twelve students enrolled in the subjects of Elective III, Mathematics Didactics, History and Epistemology of Mathematics and Degree Work II, of the VI, VII, VIII and IX semesters respectively, of the Bachelor's Degree in Mathematics (...) program; assigned to the Faculty of Education, of the Universidad Popular del Cesar. The study was situated in the qualitative paradigm, under the epistemological approach of sociocultural constructivism, with the recapitulations of the foundations and orientations of the phenomenological-transcendental methodology. It is concluded that it is feasible to change the mathematics master class for a space where students can interact in the teaching-learning process, with the necessary knowledge to understand the messages of the context of the habitat of the subject who learns; and for this reason, the relationships of the trio: Teacher-School Mathematical Knowledge-Students and these with the context can always be placed in the context of mathematics education.

Background: Heart rate variability (HRV) has been considered as a measure of heart-brain interaction and autonomic modulation, and it is modified by cognitive and attentional tasks. In cognitive tasks, HRV was reduced in participants who achieved worse results. This could indicate the possibility of HRV predicting cognitive performance, but this association is still unclear in a high cognitive load sport such as chess Objective: To analyse modifications on HRV and subjective perception of stress, difficulty and complexity in different chess problem (...) tasks. Design: HRV was assessed at baseline. During the chess problems, HRV was also monitored, and immediately after chess problems the subjective stress, difficulty and complexity were also registered. Method: A total of 16 male chess players, age: 35.19 (13.44) and ELO: 1927.69 (167.78) were analysed while six chess problem solving tasks with different level of difficulty were conducted (two low level, two medium level and two high level chess problems). Participants were classified according to their results into two groups: high performance or low performance. Results: Friedman test showed a significant effect of tasks in HRV indexes and perceived difficulty, stress and complexity in both high and low performance groups. A decrease in HRV was observed in both groups when chess problems difficulty increased. In addition, HRV was significantly higher in the high performance group than in the low performance group during chess problems. Conclusions: An increase in autonomic modulation was observed to meet the cognitive demands of the problems, being higher while the difficulty of the tasks increased. Non-linear HRV indexes seem to be more reactive to tasks difficulty, being an interesting and useful tool in chess training. (shrink)

Distributive bounded lattices with a dual homomorphism as unary operation, called Ockham algebras, were firstly studied by Berman (1977). The varieties of Boolean algebras, De Morgan algebras, Kleene algebras and Stone algebras are some of the well known subvarieties of Ockham algebra. In this paper, new results about the congruence lattice of Ockham algebras are given. From these results and Urquhart's representation theorem for Ockham algebras a complete characterization of the subdirectly irreducible Ockham algebras is obtained. These results are particularized (...) for a large number of subvarieties of Ockham algebras. For these subvarieties a full description of their subdirectly irreducible algebras is given as well.

Academic achievement is a factor of interest in both psychology and education. Determining which factors have a negative or positive influence on academic performance has produced different investigations. The present study focuses on analyzing the relationship between resilience, emotional intelligence, self-concept and the academic achievement of university students. For this purpose, different self-report tools were administered to a sample of 1,020 university students from Southern Spain. The Structural Equation-based mediational analysis suggests that there is no direct relationship between resilience and (...) academic achievement, nor between emotional intelligence and academic achievement. Likewise, self-concept is positioned as a mediating factor in the relationship between resilience and academic achievement. The findings indicate that university students who exhibit high levels of resilience tend to cope better with difficult moments and understand and value the effort required and invested in study time. This study supports positive beliefs and behaviors for better academic achievement. (shrink)
