IntroductionThe assessments of the motor symptoms in Parkinson’s disease are usually limited to clinical rating scales, and it depends on the clinician’s experience. This study aims to propose a machine learning technique algorithm using the variables from upper and lower limbs, to classify people with PD from healthy people, using data from a portable low-cost device. And can be used to support the diagnosis and follow-up of patients in developing countries and remote areas.MethodsWe used Kinect®eMotion system to capture the spatiotemporal (...) gait data from 30 patients with PD and 30 healthy age-matched controls in three walking trials. First, a correlation matrix was made using the variables of upper and lower limbs. After this, we applied a backward feature selection model using R and Python to determine the most relevant variables. Three further analyses were done using variables selected from backward feature selection model, movement disorders specialist, and all the variables from the dataset. We ran seven machine learning models for each model. Dataset was divided 80% for algorithm training and 20% for evaluation. Finally, a causal inference model using the DoWhy library was performed on Dataset B due to its accuracy and simplicity.ResultsThe Random Forest model is the most accurate for all three variable Datasets followed by the support vector machine. The CIM shows a relation between leg variables and the arms swing asymmetry and a proportional relationship between ASA and the diagnosis of PD with a robust estimator.ConclusionsMachine learning techniques based on objective measures using portable low-cost devices are useful and accurate to classify patients with Parkinson’s disease. This method can be used to evaluate patients remotely and help clinicians make decisions regarding follow-up and treatment. (shrink)

This article analyzes the autofigurative strategies of La travesía by Luisa Valenzuela in terms of the narratives of the self, the Argentine dictatorship and feminism. A correspondence is found between the disavowal of the voice, the structure of the autobiographical account and the portrait of the experience of the violence of the military regime and of gender. Initially, the novel is situated at the height of the narratives of the self that, with literary resources that are separated from the most (...) conservative autobiographical writings, denounce the impossibility of understanding the subject as univocal, while founding different approaches to the retelling of the experience. This location allows exploring the formal experiments that Valenzuela carries out around the autobiographical exercise and that highlight the crisis of the construction of memory and the exposure of contemporary subjectivity. In addition, it is shown how such strategies serve as a vehicle for reflection on feminism and dictatorship that permeate all of her work. For this, Valenzuela's notion of feminine writing is used, which puts the multiplicity of perspectives before the univocity of the autobiographical voice, the ambiguous before the precise, and the collective before the authoritarian. La travesía is, then, read as part of the works that come to the narration of the experience itself in a framework of the retelling of collective memory, with narrative games that point out the deictic futility of the self and the difficulty of recounting past time, without, therefore, abandoning the call for its reconstruction as a guarantee of non-repetition.

El presente artículo ofrece una solución al problema metaético que florece en la ética humeana a propósito de la conciliación entre el cognitivismo derivado de la exigencia del General Point of View y el internalismo moral que se deriva de su argumento de la motivación. Asumiendo una descripción evolutiva en la construcción de la perspectiva evaluativa representada por el General Point of View, al tiempo que un proyectivismo epistemológico para los juicios causales que conectan las motivaciones, acciones y utilidad de (...) los distintos caracteres que surgen en el origen de la justicia, se puede conciliar -sin riesgo para la consistencia del planteamiento humeano- la existencia de individuos capaces de generar juicios morales cognitivos que derivan en una motivación moral internalista, identificada con el sentido del deber, e individuos con motivaciones claramente externalistas basadas en el uso instrumental de la razón.

The island of Ibiza is a western Mediterranean destination known internationally for its nightlife. The aim of this paper is to make a proposal to classify the different types of premises in the Ibiza nightlife offer. This involves making a first definition that allows to delimit which businesses are parts of the sector. The methodology used is based on the case study and specifically, on the review of the promotional actions and activities carried out, completed with the visit to the (...) premises. The classification has been made based on the offer marketed and not only on the legal forms used, as innovation goes ahead of the existing legal classifications. Although it is a particular application, due to the international importance of Ibiza, it is a good starting point to classify the nightlife offer of many other tourist destinations. The resulting typology divides the sector into two large groups: nightclubs and other premises. While nightclubs have musical parties as their main activity declared, the other premises have accommodation or catering as their main activity, with music being an element of differentiation. Nightclubs are divided into several subgroups, depending on their size and relevance. The other premises are subdivided into Beach Clubs, Hotel Clubs, Party Boats, Lounge Clubs, Disco Pubs, among others. (shrink)

Uno de los problemas centrales que el filósofo francés Bernard Stiegler ha abordado para sostener una constitución tecno- lógica de la humanidad, es la cuestión del origen del hombre. El asunto recae en preguntarse si es posible pensar quién es el hombre desde esta tesis, sin volver a la metafísica o la filosofía trascendental. Esta posición ha de estar enraizada en una ontología que aprehenda el componente causal a nivel relacional, dejando de lado las explicaciones en las cuales la causa (...) es substancialista. Para dar desarrollo a esta propuesta, este artículo se compone de dos partes generales: la primera está destinada a presentar hasta dónde sigue y en dónde se separa Stiegler de la concepción zoo-antropológica de André Leroi-Gourhan sobre el origen del hombre; para luego explicar las bases epistemológicas y ontológicas sobre las que Stiegler erige sus tesis tecno-ontológica de la humanidad; a saber: los fundamentos de la transducción simondoniana y la diferancia derridiana.

This article attempts to show the importance of the concept of superstition in understanding a range of psychological problems. With this aim, we critically analyze several constructs that, without actually using the term “superstition,” concern this phenomenon and its role in the development of mental disorders. First we discuss “Thought–Action Fusion” and “magical thinking,” two concepts from the cognitive tradition that view superstition as basically an ideational phenomenon. Second, we look at “Experiential Avoidance,” a post-Skinnerian concept that understands superstition as (...) a type of avoidance behavior for certain private events. Third, we discuss superstition as an emotional phenomenon, in particular, Jean-Paul Sartre’s phenomenological analysis of emotions as magical operations. Finally, we review a cultural approach to superstition and its influence on psychopathology. In this perspective, superstition is seen as a cultural form linked to the historical–social context, which is fostered by certain social practices or institutions, including (perhaps surprisingly) certain features of modernity.

The genesis of Feynman's original approach to QED is reviewed. The main ideas of his original presentation at the Pocono Conference are discussed and compared with the ones involved in his action-at-distance formulation of classical electrodynamics. The role of the de Sitter group in Feynman's visualization of space-time processes is emphasized.

This work begins by proposing the need for exploring the mode of being of mental disorders. It is a philosophical study in an Aristotelian perspective, with special emphasis on the anthropological–cultural dimension. It is difficult for such an inquiry to be carried out from within psychiatry or clinical psychology, committed as these fields are to their own logic and practical conditions. The issues are, in any case, more ontological than strictly clinical in nature. We therefore turn to Aristotle, and specifically (...) his doctrine of the four “causes,” to flesh out the social and cultural dimensions of mental disorders. In accordance with the present analysis, the material cause of disorders would be found in the contingencies of life; the formal cause would pertain primarily to the way clinical conditions themselves can serve as models of ‘being ill’ in our society; the efficient cause would correspond to the patients themselves, understood as active (albeit less than fully conscious) agents as well as to the pharmaceutical industry and the mass media; the final cause would be found in different adaptive functions served by the disorder. We conclude that the “mode of being” of most (if not all) mental disorders—in particular, their status as mental disorders—can often have more to do with cultural forms than with biological factors.

In lieu of an abstract, here is a brief excerpt of the content:Defending a Phenomenological–Behavioral Perspective: Culture, Behavior, and ExperienceMarino Pérez-Álvarez (bio), José M. García-Montes (bio), Adolfo J. Cangas (bio), and Louis A. Sass (bio)KeywordsBehavior, contextual phenomenology, culture, experienceWe should like to express our sincere thanks to all the authors for their commentaries on our articles. Given the restrictions of space (a limitation they too had to contend with), we can only respond to a few aspects of their interesting remarks. (...) We shall reply of course on the basis of our own approach—an approach that sets out to integrate culture, behavior, and experience, and that might be termed contextual phenomenology, phenomenological behaviorism, or perhaps most accurately (albeit more awkwardly), the phenomenological–behavioral perspective.In her commentary, Ibáñez-Guerra (2008), referring to the target articles “Phenomenology and behaviorism” (Pérez-Álvarez, Sass, and Cangas 2008) and “The role of superstition in psychopathology” (García-Montes et al. 2008), wonders whether our maintaining of the spirit of Skinner, as well as our recourse to phenomenology, might not themselves represent forms of superstitious behavior. She points out that it is not always a good idea to put new wine in old barrels. For her, the new wine and new barrels would be represented by social constructivism, of which she is reminded by some aspects of our work. But in making her own case, Ibáñez-Guerra (2008) reveals certain common prejudices concerning behaviorism, prejudices that have apparently persisted even after reading our article. Thus, for example, she does not see operant behavior as incorporating intentionality (what, in the target article, is presented in terms of final causality), because she assumes that intentionality would necessarily imply a mentalist and dualist notion involving a supposed internal mental entity that causes behavior. Skinner (1974) himself noted and rejected this very assumption in a passage that clearly distinguishes his own approach from what he calls a “stimulus-response formula”: “Possibly no charge,” he wrote,is more often leveled against behaviorism or a science of behavior than that it cannot deal with purpose or intention. A stimulus-response formula has no answer, but operant behavior is the very field of purpose and [End Page 281] intention. By its nature it is directed toward the future: a person acts in order that something will happen, and the order is temporal.(pp. 55–6)The place Skinner gives to intentionality and purpose is elaborated in our target article.Furthermore, Ibáñez-Guerra (2008) assumes that, on methodological grounds, Skinner rejects all that is not observable, or at least that cannot be operationalized. This, however, is simply incorrect, at least as regards Skinner’s radical behaviorism. As the reader may recall, radical (as opposed to methodological) behaviorism is neither operationalist nor does it reject private or subjective events because of their unobservability. Indeed, Skinner specifically acknowledges that such events are in fact observable—at least for one person: the subject him- or herself. The question for Skinner is to understand how the part of the world that is only observable and experiential for oneself is constructed or formed. In the end, it turns out that radical behaviorism is more radical, in the Aristotelian ontological sense (see Pérez-Alvarez, Sass, and García-Montes 2008), than post-modern constructionism. Indeed, as we remarked, radical behaviorism can still surprise us today. Similarly, phenomenology is starting to be missed in the clinical context (Andreasen 2007). We believe that radical behaviorism and phenomenology, mutually readjusted, are in fact excellent wines for the times we live in—if only we knew how to appreciate them.In their commentary on “Phenomenology and behaviorism: A mutual readjustment,” Fletcher and Hayes (2008) argue that the philosophy and theory of Acceptance and Commitment Therapy (ACT)/Relational Frame Theory (RFT) already contain the salutary aspects of phenomenology that we highlight in our target article. Their insistence on reducing the affinities we find between phenomenology and behaviorism to ACT/RFT consists, in our view, in a scientific–technical argument that is more scientistic than strictly philosophical in nature. Their insistence on the scientific–technical argument itself implies an unclarified philosophical assumption. On what grounds do experimental data constitute the last word? Has... (shrink)

According to a growing body of studies, people’s ability to forecast future emotional experiences is generally biased. Nonetheless, the existing literature has mainly explored affective forecasting in relation to specific events, whereas little is still known about the ability to make general estimations of future emotional states. Based on existing evidence suggesting future-oriented disposition as a key factor for mental health, the aims of the current study were (1) to investigate the relationship between negative (NA) and positive (PA) affective forecasting (...) biases and perceived psychological well-being, and (2) to explore whether positively biased predictions are associated with resilience and foster one’s skills to cope with stressful events. To do so, we asked 85 undergraduate students to forecast PA and NA over two weeks, as well as to report their daily affect through a web-based Ecological Momentary Assessment. According to the results, positively biased PA forecasting (i.e., overestimating positive emotional states) was associated with greater perceived psychological well-being and higher resilience. When high levels of stress were experienced, participants holding an optimistic, yet biased, estimation of future PA were more likely to successfully manage stressors, thus maintaining lower levels of NA and higher levels of positive emotions. We suggest that positively biased PA forecasting is an adaptive cognitive distortion that boosts people’s resilience and mental health, thus opening new avenues for the promotion of psychological well-being.

The literature has recognised the fundamental role of teaching business ethics to students earning business administration degrees, but it is hard to find a methodology for teaching this topic successfully. We propose a new management tool—evidence-based administration—for the study of business ethics. The method developed on the basis of this management tool provides a practical vision to the students, motivates them, and favours the development of multiple facets of their education.

As a result of recent corporate scandals, several rules have focused on the role played by Boards of Directors on the planning and monitoring of corporate codes of ethics. In theory, outside directors are in a better position than insiders to protect and further the interests of all stakeholders because of their experience and their sense of moral and legal obligations. Female directors also tend to be more sensitive to ethics according to several past studies which explain this affirmation by (...) early gender socialization, the fact that women are thought to place a greater emphasis on harmonious relations and the fact that men and women use different ethical frameworks in their judgments. The goal of this paper is to determine the influence of these characteristics of the Board in terms of promoting and hindering the creation of a code of ethics. Our findings show that a greater number of female directors does not necessarily lead to more ethical companies. Moreover, within Europe as a continent, board ownership leads to an entrenchment of upper-level management, generating a divergence between the ethical interests of owners and managers. In light of this situation, the presence of independent directors is necessary to reduce such conflicts. (shrink)

Background. The study of entrepreneurial activity has undergone intense development in recent decades. Traditionally this topic has been addressed from three approaches: economic, sociological and psychological. In the study of enterprising personality, two fundamental perspectives stand out: the use of general personality traits, like the Big Five, and the use of more specific traits related to entrepreneurial spirit, such as self-efficacy, autonomy, innovation, optimism, and others. The objective of this study is to provide validity evidence for a new instrument for (...) measuring eight specific dimensions of entrepreneurial personality (BEPE). Method. The sample was composed of 1,170 adults from the general population (59.9% women). The average age was 42.34 years with a standard deviation of 12.96. Of the sample, 13% were self-employed. Internal factorial structure and reliability of BEPE were examined. The relationships with other variables and the discriminative capacity of the BEPE between different groups of workers were analyzed. Results. First order factor analyses show the essential unidimensionality of each of the eight proposed sub-scales, with factorial weights ranging between 0.341 and 0.825. A second-order factor analysis was carried out, obtaining a general dimension of entrepreneurial personality. With regards to reliability, the eight BEPE sub-scales gave high alpha coefficient values, between 0.825 and 0.899, as did the total battery (0.97). BEPE sub-scales show a high canonical correlation with the Big Five personality factors (.795), and with the sub-scales of the Measure of Entrepreneurial Talents and Abilities questionnaire (.815). Conclusions. The BEPE questionnaire for the evaluation of the eight fundamental specific dimensions of the entrepreneurial personality presents adequate psychometric properties. Its relationships with other measures of personality traits are in line with what is expected. Therefore, the BEPE is a new measurement instrument that can be used with confidence both in the applied field and in research. (shrink)

Background:The first wave of the COVID-19 pandemic caused a shortage of qualified nurses in Spain. As a result, the government authorized the hiring of senior students.Objectives:To explore the ethical dilemmas and ethical conflicts experienced by final-year nursing students who worked during the first outbreak of the COVID-19 pandemic in Spain.Research design:A qualitative exploratory study was conducted using purposive sampling. Semi-structured interviews were carried out using a question guide. Interviews took place via a private video chat room platform. A thematic, inductive (...) analysis was performed of the information gathered.Participants and research context:Eighteen nursing students were recruited from two universities of Madrid, aged between 18 and 65 years old, enrolled in the fourth year of nursing studies and who were hired under a relief contract for health professionals during the pandemic.Ethical considerations:The present study was carried out in accordance with the Declaration of Helsinki, and the study was approved by the Local Ethics Committee of Universidad Rey Juan Carlos.Results:Three specific themes emerged: (a) coping with patient triage, (b) difficulties in providing end-of-life care, and (c) coping with patient death. Nursing students participated in the process of patient selection for resource allocation and ICU bed occupancy. They were shown how to care for patients who were not admitted to the ICU, in their last moments and were faced with the difficulties of applying end-of-life care. Finally, the nursing students were confronted with the death of their patients, in overwhelming numbers and under adverse conditions.Conclusions:These findings can help shed light on the ethical dilemmas and ethical conflicts faced by novice nursing students, incorporated into the workforce during the COVID-19 pandemic. Moreover, it was described that students may normalize the death due to the exhaustion and overwhelmed routine. (shrink)
