El artículo postula la inmensidad de este desafío, por haber la historia conocido lealtades a, tribus, culturas, clases y naciones; pero –señala- hoy podría comenzar la historia de la humanidad como un solo pueblo. Para ello sugiere la importancia de generar un lenguaje apropiado, que entre otras cosas debiera permitirnos comprender la unidad en la diversidad. Agrega que requerimos una tercera expansión de la conciencia que nos puede llevar hacia la planetización de la conciencia humana. Nos lleva después el texto (...) a las preguntas sorbe la verdad y el significado de la indagación humana, realizando un contrapunto entre ciencia y religión. Concluye postulando la necesidad de una revolución cultural. (shrink)

The pandemic outbreak in March 2020 and its associated sanitary regulations and restrictions triggered an abrupt and significant change for society in general and for families’ organization in particular. In Chile, the Santiago Metropolitan District was under a strict lockdown that involved the closure of the entire educational system. From a systemic-family stress perspective, the impact of these changes might have consequences not only for each individual family member, but for the parental dynamic and, consequently, for children’s well-being. This paper (...) presents the results of a follow-up study showing changes in self-reported parental depression and the perceived home organization of mothers and fathers assessed at three different moments: before the pandemic, at the initial outbreak, and after 1 month of strict lockdown. Relevant moderators were explored using linear mixed models to understand the within-subject changes in mothers’ and fathers’ self-reports across the different assessment times. Financial strain, personality traits of self-criticism and dependency, previous parent–child quality interaction, recent major stressful events, and number of children are highlighted as relevant factors that moderate changes in home chaos and parental mental health perception. Significant risks and protective factors are described for fathers and mothers. The use of pre-pandemic measures as baseline levels enabled the identification of personal and family characteristics that were related to better outcomes. The results help increase our understanding of the sanitary regulations’ impacts on the family system and identify vulnerability indicators that should be considered. (shrink)

We prove that the cofinality of the smallest covering of R by meager sets is bigger than the additivity of measure.

We deal with the consistency strength of ZFC + variants of MA + suitable sets of reals are measurable (and/or Baire, and/or Ramsey). We improve the theorem of Harrington and Shelah [2] repairing the asymmetry between measure and category, obtaining also the same result for Ramsey. We then prove parallel theorems with weaker versions of Martin's axiom (MA(σ-centered), (MA(σ-linked)), MA(Γ + ℵ 0 ), MA(K)), getting Mahlo, inaccessible and weakly compact cardinals respectively. We prove that if there exists r ∈ (...) R such that ω L[ r] 1 = ω 1 and MA holds, then there exists a ▵ 1 3 -selective filter on ω, and from the consistency of ZFC we build a model for ZFC + MA(I) + every ▵ 1 3 -set of reals is Lebesgue measurable, has the property of Baire and is Ramsey.

A thermal-mechanical analysis of the behavior of the segments of the rollers of the briquetting machines is carried out due to the effect of thermal shock and efforts exerted on the part. It is intended to obtain the main causes that generate this problem, through a mechanical analysis that simulated the behavior in the presence of several thermal gradients. The purpose of the study is to reduce maintenance costs and the continuous replacement and repair of segments, as well as losses (...) in tons of production due to the failure that are of great impact to the industry. This investigation allows us to know to what extent the operating parameters, such as: material temperature, pressure, torque, speed of the rollers influence the life of the segments according to their manufacturing material and based on these the behavior is simulated during the briquetting process.

After a long and successful career in tracheal surgery and lung cancer, Paolo Macchiarini became very famous in 2008 with the transplantation of a trachea from a cadaver that then apparently used the patient’s own stem cells to supposedly regenerate new trachea, i.e., tissue-engineered tracheae. Among the nine patients that received this revolutionary treatment, using biological or artificial tracheae, under Macchiarini’s supervision, six have reportedly died. Although several critics had expressed concerns with the procedures, allegations of misconduct against Macchiarini first (...) arose in August of 2014 by four Karolinska Institutet (KI) colleagues, and an independent investigation was called for by KI based on claims made in seven published papers. Among the claims were the fact that the procedure constituted a high risk, information on the patients was incomplete and that there was no or incomplete ethical approval, thus constituting misconduct. His CV was also shown to contain inaccuracies. By September 10, 2016, most of these claims have now proved to be true, and Macchiarini was found guilty of misconduct by KI. This paper looks primarily at earlier published papers by Macchiarini and his collaborators in a search for clues to better understand the evolution of altruism, or narcissism. An assessment of the controversial papers, and of letters written by critics and skeptics like Pierre R. Delaere, indicate that insufficient experimental evidence was presented for several case studies, and that claims made about the success of the procedures exceeded what was shown by the evidence. A domino effect of personal and professional tragedies ensued, in rapid succession, between 2014 and 2016. The effect on the field of stem cell research has been chilling, and the side-effects have taken their toll, with several high-profile resignations, primarily at KI, within the Swedish education system and in the Nobel Committee. This case has mesmerized the bioethics and biomedical communities for years. (shrink)

Clinical and Care Bioethics Committees at Public and Private Healthcare Institutions of Medium and High Complexity Levels in Cities of the Atlantic Coast of Colombia Comitês de Bioética clínico-assistencial nas instituições de saúde públicas e privadas dos níveis de média e alta complexidade das cidades da Costa Atlântica da Colômbia Care bioethics committees are interdisciplinary groups engaged in providing education to members of said committees, all the staff in the hospital —including professors and students in their internship—, and members of (...) the community. The objective of this study is to determine the situation of clinical and care bioethics committees at healthcare institutions in the Atlantic Coast of Colombia between 2010-2016. The study is cross-sectional, descriptive, and retro-prospective. Twenty-six health institutions that met the inclusion criteria were selected and administered a semi-structured survey. The statistical software SPSS version 22 was used to analyze the information. This study adhered to ethical research guidelines. The name most commonly given to committees is Hospital Ethics Committee. Only half have staff trained in ethics or bioethics and the most outstanding function is education in ethics; however, in the same percentage there are committees whose opinion is divided as their operation is unclear. Committees should follow existing ethical and bioethical models, and bills should be brought forward to help committees at healthcare institutions become more effective as regards their structure and operation.

We find before us an excellent edition of the book which the influential American thinker Ralph Waldo Emerson (1802-82) published in December of 1860, four months before the outbreak of the American Civil War. The central question which Emerson poses in this volume concerns the conduct of life, that is, of how to live. The titles of the nine essays, which compose the book, illustrate the themes tackled: “Fate,” “Power,” “Wealth”, “Culture,” “Behavior,” “Worship”, “Considerations by the Way,” “Beauty” and “Illusions.” (...) As Callaway suggests, Emerson’s is not a philosophy in the sense of contemporary technicalities, “the basic tendency of his thought is a metaphysical idealism in which the soul and intuition or inspiration are central.” (p. xvi). As an essentially religious thinker, profoundly preoccupied with the human soul and with the development of human potentialities, he has always firmly opposed to slavery: one cannot refuse to others human beings the development of their distinctively human potentialities (p. xxvii).

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)

In a world of ever growing specialization, the idea of a unity of science is commonly discarded, but cooperative work involving cross-disciplinary points of view is encouraged. The aim of this paper is to show with some textual support that Charles S. Peirce not only identified this paradoxical situation a century ago, but he also mapped out some paths for reaching a successful solution. A particular attention is paid to Peirce's classification of the sciences and to his conception of science (...) as a collective and cooperative activity of all those whose lives are animated by the desire to discover the truth. -/- .

Building upon the insights of scholars attuned to story, narrative, and myth, this article explores the relationship between myth, science, and religion. After clarifying the interplay of the three terms—story, narrative, and myth—and the preference for the term myth, this article will argue that myth can serve as a medium through which religion, neuroscience, and mental well‐being interact. Such an exploration will cover the role of myths in religion, the neurological basis of myth, and the practices of narrative psychology and (...) bibliotherapy. The article will conclude with suggestions for understanding and utilizing the relationship between myth and the scholarly study of the relationship between science and religion. This article ultimately suggests that myth can operate as a methodological aid to the science‐and‐religion field. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:To Nurse BetterJaime HenselWhen things were quiet again I asked him what training he’d had to become the director of hospital security. “I worked for 20 years in corrections,” he answered proudly, and I was saddened but not surprised.In September 2010 I started an accelerated graduate entry nurse practitioner program to become a family nurse practitioner. Accelerated programs leave little time for preamble, since the idea is to take (...) a total novice and turn her first into a nurse and then into a nurse practitioner in just three years. While the classroom information was vital, it was our clinical experiences that really initiated us into the profession. In just the second week of school, we were divided into small groups and assigned to clinical preceptors—hands–on teachers who introduced us to our first patients, curbed our mistakes, quelled our fears, and pushed and pulled and cajoled us into being nascent healthcare providers. In showing us how to give bed baths, suction secretions, insert Foley catheters, and hang IV bags, our preceptors really began showing us how to use our hands as healers.In that first semester my patients also proved to be invaluable instructors. Talking to them, administering their medication, washing their bodies made me keenly aware of the delicate balance of vulnerability and power and trust and respect and intimacy that underlies all healthcare relationships. I hope, wherever those patients are now, they know how deeply I appreciate their patience and good humor and their collusion in my education.In December, the first semester and the first clinical rotations ended. Four months into nursing school I had a basic understanding of what it means to be a nurse. Frankly, most days I still felt like an impostor in blue pajamas sporting a stethoscope I didn’t really know how to use and new Dansko clogs that squeaked with every step. But in an accelerated program, fast and furious is the name of the game. We went away for winter break—a much needed breather—and came back to something completely different: psychiatric nursing.In preparation for these new clinicals, we were taught in class that we should not wear dangly jewelry or stethoscopes. That we should never let the patient get between us and the door. That psychiatric (psych) patients could escalate quickly; psych patients could have surprising triggers; psych patients could be very unpredictable. And psych patients could be violent. We were taught about physical and chemical restraints, and about show of force. We were cautioned, as students, to stay out of the way if things got tense on the floor. In stark contrast to medical patients, psych patients were made to sound less like people who had diseases and more like adversaries. I drove to my first day on the floor with trepidation.My new preceptor had spent her entire career in psych. She loved her job, loved the care of psychiatric patients. She set up a rotation because she wanted our entire clinical group to get full exposure to the breadth of psychiatric services offered by this medium–sized community hospital. We would each get to spend shifts on the locked psych floor, observing outpatient group therapy sessions, and in the psych emergency department (ED).I rotated to the psych ED for the first time on a Friday night. The first couple hours of the shift were very slow. I started talking to the mustachioed guard on duty, who looked as bored as I felt. He told me about his kids, I told him about nursing school. He seemed nice.When our conversation flagged, I explored the psych ED. It didn’t take long—just a short hallway with a bathroom, the social workers’ office, and two patient rooms without doors. The majority of the designated psych beds were actually around the corner in the main room of the medical ED—stretchers lined against the wall, without curtains or any [End Page 98] other attempt at privacy. I noticed that from where the guard stood at the corner of the psych hall he had a pretty good view of all the beds. Then again, so did most of the other patients... (shrink)

Once hematopoiesis is established in the bone marrow, a continuous egress of hematopoietic stem cells (HSCs) to the periphery occurs at a low frequency. It has been proposed that this phenomenon is part of a regenerative homeostatic mechanism that ensures the maintenance of hematopoiesis through the life of the individual. The administration of certain cytotoxic drugs or cytokines can enhance the mobilization of hematopoietic progenitors to the periphery. During the past 15 years, granulocyte‐colony stimulating factor (G‐CSF) has been used as (...) a standard cytokine for mobilization protocols in experimental models and in humans. Despite extensive efforts by multiple groups, a definitive mechanism explaining its role in mobilization has not been provided. In a recent paper, Katayama et al.,1 through a series of clever associations supported by well‐defined experimental systems, proposed that signals through the sympathetic nervous system modify the activity of the hematopoietic niche, acting as regulators of the mobilization of hematopoietic progenitors. This surprising finding adds a new level of complexity to the cellular milieu responsible for generation and maintenance of the hematopoietic niche.

This article is a response to Josh Reeves's recent book Against Methodology in Science and Religion: Recent Debates on Rationality and Theology that welcomes Reeves's proposal for an anti‐essentialist future for the field of science‐and‐religion, particularly because it has the potential to move the field beyond current, well‐worn methods: the dominance of Christian theology and doctrine, the importance of credibility strategies, and the dependence upon philosophical discourses. Reeves’ proposal has the potential to open the science‐and‐religion field to other topics, problems, (...) and methods, such as studying lived science‐and‐religion. One way of doing this is to study popular culture and its artifacts such as literature, which portrays a co‐mingling of religion and science at the level of day‐to‐day experiences and practices of characters. For at the level of lived experience, religion and science are not well‐defined disciplines neatly compartmentalized into separate academic departments. (shrink)

Climate change exacts a devastating toll on health that is rarely incorporated into the economic calculus of climate action. By aligning health and environmental policy and collaborating across borders, governments and industries can develop powerful initiatives to promote both environmental and human health.

In this paper the relations between the almost unknown Spanish mathematician Ventura Reyes Prósper (1863-1922) with Charles S. Peirce and Christine Ladd-Franklin are described. Two brief papers from Reyes Prósper published in El Progreso Matemático 12 (20 December 1891), pp. 297-300, and 18 (15 June 1892) pp. 170-173 on Ladd-Franklin, and on Peirce and Mitchell, respectively, are translated for first time into English and included at the end of the paper.
