Background: Treating medication-refractory freezing of gait in Parkinson’s disease remains challenging despite several trials reporting improvements in motor symptoms using subthalamic nucleus or globus pallidus internus deep brain stimulation. Pedunculopontine nucleus region DBS has been used for medication-refractory FoG, with mixed findings. FoG, as a paroxysmal phenomenon, provides an ideal framework for the possibility of closed-loop DBS.Methods: In this clinical trial, five subjects with medication-refractory FoG underwent bilateral GPi DBS implantation to address levodopa-responsive PD symptoms with open-loop stimulation. Additionally, PPN (...) DBS leads were implanted for CL-DBS to treat FoG. The primary outcome of the study was a 40% improvement in medication-refractory FoG in 60% of subjects at 6 months when “on” PPN CL-DBS. Secondary outcomes included device feasibility to gauge the recruitment potential of this four-lead DBS approach for a potentially larger clinical trial. Safety was judged based on adverse events and explantation rate.Findings: The feasibility of this approach was demonstrated as we recruited five subjects with both “on” and “off” medication freezing. The safety for this population of patients receiving four DBS leads was suboptimal and associated with a high explantation rate of 40%. The primary clinical outcome in three of the five subjects was achieved at 6 months. However, the group analysis of the primary clinical outcome did not reveal any benefit.Interpretation: This study of a human PPN CL-DBS trial in medication-refractory FoG showed feasibility in recruitment, suboptimal safety, and a heterogeneous clinical effect in FoG outcomes.

_Defensione delle donne_, de Agostino Strozzi, es una de las obras filóginas más significativas en lengua italiana compuesta a finales del siglo XV. Nos consta la existencia de dos versiones recogidas en dos manuscritos que presentan contrastes significativos entre ambas. Una de ellas más extensa y, sobre todo, más radical en sus argumentos en defensa de las virtudes femeninas, está dedicada a su prima Margherita Cantelmo. En esta comunicación se describe y profundiza en los contrastes presentes en ambas versiones o, (...) dicho con otras palabras, en lo que podemos considerar como dos misteriosos manuscritos.

The global impact of Dobbs v. Jackson Women’s Health Organization and the backlash towards reproductive justice that it represents warrant a global feminist response informed by broad theoretical and geopolitical lenses. We consider how a solidaristic, transnational feminist movement might learn from Latin American feminist movements that have been successful in uniting broad coalitions in the fight for reproductive justice as situated within far-reaching political goals. The success of such a global movement must be decolonial and must contend with the (...) fact that overlapping realities of global inequality, severe poverty, extractivism, and western-backed violence are fundamentally implicated in reproductive justice.

The idea of food sovereignty has its roots primarily in the response of small producers in developing countries to decreasing levels of control over land, production practices, and food access. While the concerns of urban Chicagoans struggling with low food access may seem far from these issues, the authors believe that the ideas associated with food sovereignty will lead to the construction of solutions to what is often called the “food desert” issue that serve and empower communities in ways that (...) less democratic solutions do not. In Chicago and elsewhere, residents and activists often see and experience racial and economic inequalities through the variety of stores and other food access sites available in their community. The connections between food access, respect, and activism are first considered through a set of statements of Chicagoans living in food access poor areas. We will then discuss these connections through the work and philosophy of activists in Chicago centered in food sovereignty and food justice. Particular focus will be placed on Growing Power, an urban food production, distribution, and learning organization working primarily in Milwaukee and Chicago, and Healthy South Chicago, a community coalition focused on health issues in a working class area of the city.

Radical enactivism supports radical embodied cognition (REC), which is the idea that basic or fundamental cognition (perception and action) does not need to be understood in representational, contentful terms. REC departs from the idea that the mind can be naturalized through biological functions, but rejects the idea that mental content, which is understood as having a representational nature, can be naturalized. For REC, the natural origins of content (or NOC) is a program based on the following hypothesis: first, we depart (...) from basic cognitive processes that are target-based and guided by an Ur-intentionality or directedness toward the world, and then sociality enters in the picture when language appears into the scene, allowing for establishing full-blown semantic content in which that content is about worldly states of affairs. Here, we are going to focus on the phenomenon of directedness since there are blind spots in this picture: as many authors claim, REC takes Ur-intentionality as the starting point, but there is simply no explanation to date of how this directedness or Ur-intentionality is established. Therefore, how could we account for Ur-intentionality? How does this kind of intentionality emerge? We believe that we can answer this question if we invoke the best scientific evidence from ecological perceptual learning especially in regard to the role of the environment and the information for perceiving affordances in our learning processes. This allows us to offer an answer to the question of how the most basic form of cognition (Ur-intentionality or directedness) emerges in nature. (shrink)

Background: COVID-19 has taken many lives worldwide and due to this, millions of persons are in grief. When the grief process lasts longer than 6 months, the person is in risk of developing Complicated Grief Disorder. The CGD is related to serious health consequences. To reduce the probability of developing CGD a preventive intervention could be applied. In developing countries like Mexico, the psychological services are scarce, self-applied interventions could provide support to solve this problem and reduce the health impact (...) even after the pandemic has already finished.Aims: To design and implement a self-applied intervention composed of 12 modules focused on the decrease of the risk of developing CGD, and increasing the life quality, and as a secondary objective to reduce the symptomatology of anxiety, depression, and increase of sleep quality. The Intervention Duelo COVID follows the principles of User Experience and is designed according to the needs and desires of a sample of the objective participants, to increase the adherence to the self-applied intervention, considered one of the main weaknesses of online interventions.Methods: A Randomized Controlled Trial will be conducted from the 22nd of December of 2020 to the first of June 2021. The participants will be assigned to an intervention with elements of Cognitive Behavioral Therapy, Acceptance and Commitment Therapy, Mindfulness and Positive Psychology. The control group will be a wait-list condition, that will receive the intervention 1.5–2 months after the pre-measurement were taken. The Power Size Calculation conducted through G*Power indicated the need for a total of 42 participants, which will be divided by 21 participants in each group. The platform will be delivered through responsive design assuring with this that the intervention will adapt to the screen size of cellphones, tablets, and computers.Ethics and Dissemination: The study counts with the approval of the Research Ethics Committee of the Autonomous University of Ciudad Juárez, México, and it is registered in Clinical Trials. The article is sent and registered in clinical trials before the recruitment started. The results will be reported in future conferences, scientific publications, and media. (shrink)

The health emergency due to the COVID-19 pandemic revealed limitations in health systems worldwide, making it necessary to establish a bioethical framework that provides tools to drive health professionals’ decision-making amid scarce health resources. Bioethical models such as principlism, utilitarianism, and personalism seek to focus clinical decisions on respect for people’s rights and dignity, thus protecting the medical practice. Personalism provides a person-centered approach to respect for human dignity during health emergencies to avoid giving material meaning to the individual. Decision (...) criteria are required to face bioethical conflicts in clinical practice, reducing the legal, emotional, and ethical burden of decision-making in pandemic situations. (shrink)

Background: Mental fatigue can impact physical demands and tactical behavior in sport-related contexts. Small-sided games are often used to develop a specific sport-related context. However, the effects of mental fatigue on physical demands and tactical behaviors during soccer SSGs have not been aggregated for systematical assessment.Objective: This systematic review was conducted to compare the effects of mental fatigue vs. control conditions in terms of the total running distance and tactical behavior of soccer players during SSGs.Methods: The data sources utilized were (...) PubMed, PsycINFO, Scielo, Scopus, SPORTDiscus, and Web of Science. The study eligibility criteria were established based on PICOS: Population: healthy youth and young adult men soccer players with regular training practice and belonging to teams with regular competitions; Intervention: exposed to mental fatigue-induced protocols only before SSGs; Comparator: control conditions before SSGs; Outcomes: physical demands and tactical behavior ; Study design: counterbalanced cross-over design; and only full-text and original articles written in English.Results: The database search initially identified 111 titles. From those, six articles were eligible for the systematic review and meta-analysis. Results showed no significant effect of fatigue on total running distance and tactical behavior.Conclusions: A non-significant effect of mental fatigue on total running distance and tactical behaviors performed by soccer players during SSGs was found in this systematic review.

The lambda calculus is a universal programming language. It can represent the computable functions, and such offers a formal counterpart to the point of view of functions as rules. Terms represent functions and this allows for the application of a term/function to any other term/function, including itself. The calculus can be seen as a formal theory with certain pre-established axioms and inference rules, which can be interpreted by models. Dana Scott proposed the first non-trivial model of the extensional lambda calculus, (...) known as $ D_{\infty }$, to represent the $\lambda $-terms as the typical functions of set theory, where it is not allowed to apply a function to itself. Here we propose a construction of an $\infty $-groupoid from any lambda model endowed with a topology. We apply this construction for the particular case $D_{\infty }$, and we see that the Scott topology does not provide enough information about the relationship between higher homotopies. This motivates a new line of research focused on the exploration of $\lambda $-models with the structure of a non-trivial $\infty $-groupoid to generalize the proofs of term conversion to higher-proofs in $\lambda $-calculus.

BackgroundUndocumented immigrants can donate their organs, but lack access to organ transplantation. This challenges foundational principles of organ donation: fairness and informed consent. Little is known about undocumented immigrants’ knowledge of barriers to their access to organ transplantation or how this might affect their decision to donate their organs.MethodsThe study was performed in an urban, university-affiliated, safety-net hospital. We interviewed hospitalized patients who selfidentified as undocumented immigrants and were unaware of having any contraindication to organ donation (for example, cancer). We (...) first recorded their demographic characteristics and knowledge and attitudes regarding organ donation. We then assessed the effects of informing participants about limits to their access to organ transplants on their willingness to donate.ResultsThis group of 59 uninsured Hispanic immigrants had adequate knowledge about organ donation. Participants were suspicious about inequality within the medical system, but most were willing to donate their organs (74 percent). Most participants (74 percent) were aware that they would have to pay to receive an organ, but they dramatically underestimated the out-of-pocket expenses. Yet willingness to donate their organs was unaffected by participants being explicitly informed of the low likelihood that they would be able to afford to receive an organ transplant.ConclusionsDespite being well informed about the organ donation system, undocumented Hispanic immigrants underestimate the costs and overestimate their likelihood of receiving an organ. Even when they are given this information, they remain willing to donate their own organs. (shrink)

En este artículo se parte del planteamiento de Merleau-Ponty del cuerpo como una existencia ambigua, que no se puede reducir a un mero sujeto o a una mera cosa. Esto lleva a explorar el cuerpo desde ambas perspectivas. En primer lugar, se analiza el cuerpo como un objeto producto de las representaciones del capitalismo cognitivo y del sistema farmacopornográfico de poder descrito por Paul Beatriz Preciado. En segundo lugar, se analiza el cuerpo como sujeto, como elemento que posibilita la acción (...) política, a partir de las reflexiones que han realizado Judith Butler y Jacques Rancière en torno al cuerpo vulnerable y al cuerpo estético, respectivamente. De esta manera, se encuentra que si bien el cuerpo se encuentra atravesado por los diferentes dispositivos de poder del capitalismo contemporáneo, así mismo en este se encuentra la potencialidad de resistencia y emancipación frente a estos mecanismos.

An appropriate framework is put forward for the construction of $$\lambda $$ -models with $$\infty $$ -groupoid structure, which we call homotopic $$\lambda $$ -models, through the use of an $$\infty $$ -category with cartesian closure and enough points. With this, we establish the start of a project of generalization of Domain Theory and $$\lambda $$ -calculus, in the sense that the concept of proof (path) of equality of $$\lambda $$ -terms is raised to higher proof (homotopy).

This book studies geoethics in Latin America and offers comprehensive research on geoethics and geoeducation. Its respective chapters explore geoethics in relation to UNESCO geoparks, mining activities in Latin America, natural hazards and risk management. Geoethics is a key discipline in the field of Earth and Planetary Sciences, and not only includes scientific, technological, methodological and social-cultural aspects, but also addresses the need to consider appropriate protocols, scientific integrity issues and a code of good practice when studying the abiotic world. (...) The position of Latin America’s recently created geoethics associations is based on protection of the environment, together with a reassurance that the balance of nature and the rights of human beings to enjoy it will be preserved.

One takes advantage of some basic properties of every homotopic \(\lambda\)-model (e.g. extensional Kan complex) to explore the higher \(\beta\eta\)-conversions, which would correspond to proofs of equality between terms of a theory of equality of any extensional Kan complex. Besides, Identity types based on computational paths are adapted to a type-free theory with higher \(\lambda\)-terms, whose equality rules would be contained in the theory of any \(\lambda\)-homotopic model.

Music can reduce stress and anxiety, enhance positive mood, and facilitate social bonding. However, little is known about the role of music and related personal or cultural variables in maintaining wellbeing during times of stress and social isolation as imposed by the COVID-19 crisis. In an online questionnaire, administered in 11 countries, participants rated the relevance of wellbeing goals during the pandemic, and the effectiveness of different activities in obtaining these goals. Music was found to be the most effective activity (...) for three out of five wellbeing goals: enjoyment, venting negative emotions, and self-connection. For diversion, music was equally good as entertainment, while it was second best to create a sense of togetherness, after socialization. This result was evident across different countries and gender, with minor effects of age on specific goals, and a clear effect of the importance of music in people's lives. Cultural effects were generally small and surfaced mainly in the use of music to obtain a sense of togetherness. Interestingly, culture moderated the use of negatively valenced and nostalgic music for those higher in distress. (shrink)

BackgroundStudies and meta-analyses found individual, meso and micro-social factors that are associated with individual well-being, as well as a positive socio-emotional climate or collective well-being.AimThis article simultaneously studies and examines these factors of well-being.MethodWell-Being is measured as a dependent variable at the individual and collective level, as well as the predictors, in three cross-sectional and one longitudinal studies. Education and social intervention workers from Chile, Spain and Uruguay participate; a subsample of educators from the south central Chile and from Chile, (...) Uruguay and Spain ; workers from organizations in Latin America and Southern Europe, military cadets from Argentina ; and teams from Spanish companies.ResultsIndividual and collective well-being indicators were related, suggesting that the emotional climate as a context improves personal well-being. Individual factors, psychosocial factors were positively associated with personal well-being in education and social intervention context. Organizational dynamic or transformational culture is directly and indirectly associated with individual well-being through previously described psychosocial factors. Group processes such as internal communication and safe participation, task orientation or climate of excellence as well as leadership style that reinforces participation and belonging, were positively associated with collective well-being in labor and military context and predict team work socio-emotional climate in a longitudinal study- but were unrelated to individual well-being. Transformational leadership plays a mediating role between functional factors and social-emotional climate in work teams. Organizational role autonomy, functional organizational leadership, integration and resources were associated with collective well-being in organizations. Organizational leadership moderates the relationship between task orientation and collective well-being in military context.ConclusionIndividual and microsocial factors influence personal well-being. Meso level factors favorable to well-being through processes which reinforce social belonging, influence directly collective well-being and indirectly personal well-being. Leadership that reinforces participation and belonging play a central role for emotional climate. Stress and emotional climate playing an important pivotal role for psychological well-being.

The strict lockdown experienced in Spain during March–June 2020 as a consequence of the COVID-19 crisis has led to strong negative emotions. Music can contribute to enhancing wellbeing, but the extent of this effect may be modulated by both personal and context-related variables. This study aimed to analyze the impact of the two types of variables on the perceived efficacy of musical behaviors to fulfill adults’ emotional wellbeing-related goals during the lockdown established in Spain. Personal variables included age, gender, musical (...) training, personality, resilience, and perception of music’s importance. Contextual variables referred to living in a region with a high COVID-19 impact, perception of belonging to a risk group, being alone, having caring responsibilities during confinement, and amount of time of music listening as compared to prior to the crisis. The study was conducted retrospectively during August–December 2020, when the strict lockdown was over in Spain. An online survey was disseminated among the general population and groups of musicians, and the answers of 507 adults were analyzed. Only personal, but not COVID-19 context-related variables, showed an impact on music’s efficacy. The youngest age group of adults and those with musical training reported the highest efficacy of music for wellbeing enhancement, and music’s importance was found to be the main significant predictor of music’s perceived efficacy. Our findings suggest that the people who have been reported to be emotionally more vulnerable during the lockdown, due to either a strong impact on their daily lives or their lower resilience, perceive a higher benefit from musical behaviors. Being musically trained, even for a small number of years, also leads to a perception of higher efficacy of music for the achievement of emotional wellbeing goals. However, this effect is explained by the musically trained individuals’ higher perception of music’s importance. Although musical behaviors can be generally considered as important for wellbeing enhancement, our study highlights who are the potential individuals who could benefit the most from music-related activities for obtaining better levels of wellbeing, at least within the current context of the COVID-19 crisis.

The purpose of this paper is to study the philosophical basis of the architecture of two Artificial Intelligence systems (AlphaGo and Hide and Seek). The problem considers the elucidation of the epistemological distinction between “knowledge” and “intuition” and questions whether the fulfillment of a programmed metric can be considered as a product of knowledge or, as an example of intuitive thinking. Through the analysis of both examples, it is shown that achieving the desired objective (winning a game of Go and (...) developing new hiding strategies) is not derived from the system’s architecture, but from the AI’s creativity to achieve the desired result; in that sense, it can be confirmed that certain intelligent systems are capable of creative and intuitive thinking. El objetivo del presente artículo es estu- diar los fundamentos filosóficos de la arquitectura de programación en dos sistemas de Inteligencia Artificial (AlphaGo y Hide and Seek). El problema dilucida la distinción epistemológica de los concep- tos “conocimiento”, “intuición” y “abducción”, para definir si el cumplimiento exitoso de una métrica programada, por parte de una computadora, es con- dición suficiente para atribuirle un comportamiento inteligente. A través del análisis de ambos ejemplos se muestran dos cuestiones: i) el cumplimiento exitoso de un objetivo programado ofrece nuevos recursos de conocimiento, ii) dichos conocimientos dependen de la ejecución de un programa cuyo pro- cesamiento es desarrollado por una IA y, por tanto, las operaciones superan las capacidades intelectivas humanas. Las conclusiones apuntan a que las com- putadoras son recursos de conocimiento especiales de comprobación de hipótesis. (shrink)

After two decades in the 21st Century, and despite all the advances in the area, some very important names from past centuries still do not have the recognition they deserve in the global history of library and information science and, specifically, of knowledge organization. Although acknowledged in British librarianship, the name of James Duff Brown still does not have a proper recognition on a global scale. His contributions to a free and more democratic library had a prominent place in the (...) works and projects he developed during his time at the libraries of Clerkenwell and Islington in London. Free access to the library shelves, an architecture centered on books and people, and classifications that are more dynamic were dreams fulfilled by Brown. With this biographical article, we hope to live up to his legacy and pay homage to a true librarian and an advocate of the public library and subject classification. (shrink)

The concepts of “good” and “bad” are associated with right and left space. Individuals tend to associate good things with the side of their dominant hand, where they experience greater motor fluency, and bad things with their nondominant side. This mapping has been shown to be flexible: Changing the relative fluency of the hands, or even observing a change in someone else's motor fluency, results in a reversal of the conceptual mapping, such that good things become associated with the side (...) of the nondominant hand. Yet, based on prior studies, it is unclear whether space–valence associations were determined by the experience of fluent versus disfluent actions, or by the mere expectation of fluency. Here, we tested the role of expected fluency by removing motor execution and perceptual feedback altogether. Participants were asked to imagine themselves performing a psychomotor task with one of their hands impaired, after which their implicit space–valence mapping was measured. After imagining that their right hand was impaired, right-handed participants showed the “good is left” association typical of left-handers. Motor imagery can change people's implicit associations between space and emotional valence. Although asymmetric motor experience may be necessary to establish body-specific associations between space and valence initially, neither motoric nor perceptual experience is needed to change these associations subsequently. The mere expectation of fluent versus disfluenct actions can drive fluency-based effects on people's implicit spatialization of “good” and “bad.” These results suggest a reconsideration of the mechanisms and boundary conditions of fluency effects.

Há uma filosofia da diferença que precisa ser mais considerada nos nossos tempos, visto que se opõe à tradição filosófica identitária dos pré-socráticos à atualidade, que se apegou obstinadamente à ideia de identidade, que vislumbra o real, somente através da referência ao idêntico.

Over the last few decades, the Internet has brought about a myriad of benefits to almost every aspect of our daily lives. However, malware attacks have also widely proliferated, mainly aiming at legitimate network users, resulting in millions of dollars in damages if proper protection and response measures are not settled and enforced. In this context, the paper at hand proposes MalSEIRS, a novel dynamic model, to predict malware distribution in a network based on the SEIRS epidemiological model. As a (...) result, the time-dependent rates of infection, recovery, and loss of immunity enable us to capture the complex dynamism of malware spreading behavior, which is influenced by a variety of external circumstances. In addition, we describe both offensive and defensive techniques, based on the proposed MalSEIRS model, through extensive experimentation, as well as disclosing real-life malware campaigns that can be better understood by using the suggested model.

Child-to-parent violence is a growing public health problem with consequences for perpetrators and families. Most research has focused on individual and family risk factors. However, little is known about its links with individual outcomes. The aim of this study was to analyze the relationships between CPV and psychological distress, suicidal ideation, and self-concept in school-aged adolescents, taking into account the gender perspective. A study was conducted with a sample of 8,115 adolescents, aged between 11 and 16 years from the State (...) of Nuevo León, Mexico. A MANOVA 3 × 2 was performed to analyze the data. The results revealed that adolescents involved in CPV showed higher levels of psychological distress and suicidal ideation and lower levels of family and social self-concept. It was also observed that girls with higher levels of CPV scored the lowest levels of psychological distress and suicidal ideation, as well as the lowest levels of family self-concept. The findings highlight that adolescents and especially girls involved in CPV also report internal maladjustment outcomes. Finally, the results and their implications for research and intervention with adolescents involved in CPV are discussed. (shrink)

This article examines four leading multi-stakeholder labour monitoring organizations. All operating in the maquiladora industry, these organizations are viewed in light of the growing global trend toward industry self-regulation, or what has been referred to as the 'global out-sourcing of regulation'. Their Board compositions, codes of conduct and monitoring and enforcement strategies are all examined as a means of tentatively positioning these organizations along an 'egoist-instrumentalist-moralist' ethical culture continuum. Such a framing provides insights into the perceived salience of these organizations' (...) broader stakeholders, the effectiveness of codes of conduct on workplace practices more generally, and the role that ethics plays in the governance and accountability of these increasingly important types of organizations.
