This project seeks to highlight the benefits of the implementation and management of the teaching digital portfolio. In today's world full of technology and tools that facilitate daily activities, education and its various processes must also embrace the digital tools available and make them the basis for any innovation and improvement process. The teaching portfolio in physics has long been the means by which teachers have organized the processes, evidence, and other results of educational work. Nowadays, all that range of (...) evidence and productions, which signify the achievement and advances in each group of students, has been able to be integrated into technology. (shrink)

Transdisciplinary research knits together knowledge from diverse epistemic communities in addressing social-environmental challenges, such as biodiversity loss, climate crises, food insecurity, and public health. This paper reflects on the roles of philosophy of science in transdisciplinary research while focusing on Indigenous and other subaltern forms of knowledge. We offer a critical assessment of demarcationist approaches in philosophy of science and outline a constructive alternative of transdisciplinary philosophy of science. While a demarcationist focus obscures the complex relations between epistemic communities, transdisciplinary (...) philosophy of science provides resources for meeting epistemic and political challenges of collaborative knowledge production.

Families play an essential role in deceased organ procurement. As the person cannot directly communicate his or her wishes regarding donation, the family is often the only source of information regarding consent or refusal. We provide a systematic description and analysis of the different roles the family can play, and actions the family can take, in the organ procurement process across different jurisdictions and consent systems. First, families can inform or update healthcare professionals about a person’s donation wishes. Second, families (...) can authorize organ procurement in the absence of deceased’s preferences and the default is not to remove organs, and oppose donation where there is no evidence of preference but the default is to presume consent; in both cases, the decision could be based on their own wishes or what they think the deceased would have wanted. Finally, families can overrule the known wishes of the deceased, which can mean preventing donation, or permitting donation when the deceased refused it. We propose a schema of 4 levels on which to map these possible family roles: no role, witness, surrogate, and full decisional authority. We conclude by mapping different jurisdictions onto this schema to provide a more comprehensive understanding of the consent system for organ donation and some important nuances about the role of families. This classificatory model aims to account for the majority of the world’s consent systems. It provides conceptual and methodological guidance that can be useful to researchers, professionals, and policymakers involved in organ procurement. (shrink)

The organ donation and transplantation (ODT) system heavily relies on the willingness of individuals to donate their organs. While it is widely believed that public trust plays a crucial role in shaping donation rates, the empirical support for this assumption remains limited. In order to bridge this knowledge gap, this article takes a foundational approach by elucidating the concept of trust within the context of ODT. By examining the stakeholders involved, identifying influential factors, and mapping the intricate trust relationships among (...) trustors, trustees, and objects of trust, we aim to provide a comprehensive understanding of trust dynamics in ODT. We employ maps and graphs to illustrate the functioning of these trust relationships, enabling a visual representation of the complex interactions within the ODT system. Through this conceptual groundwork, we pave the way for future empirical research to investigate the link between trust and organ donation rates, informed by a clarified understanding of trust in ODT. This study can also provide valuable insights to inform interventions and policies aimed at enhancing organ donation rates. (shrink)

To analyze which ethically relevant biases have been identified by academic literature in artificial intelligence algorithms developed either for patient risk prediction and triage, or for contact tracing to deal with the COVID-19 pandemic. Additionally, to specifically investigate whether the role of social determinants of health have been considered in these AI developments or not. We conducted a scoping review of the literature, which covered publications from March 2020 to April 2021. ​Studies mentioning biases on AI algorithms developed for contact (...) tracing and medical triage or risk prediction regarding COVID-19 were included. From 1054 identified articles, 20 studies were finally included. We propose a typology of biases identified in the literature based on bias, limitations and other ethical issues in both areas of analysis. Results on health disparities and SDOH were classified into five categories: racial disparities, biased data, socio-economic disparities, unequal accessibility and workforce, and information communication. SDOH needs to be considered in the clinical context, where they still seem underestimated. Epidemiological conditions depend on geographic location, so the use of local data in studies to develop international solutions may increase some biases. Gender bias was not specifically addressed in the articles included. The main biases are related to data collection and management. Ethical problems related to privacy, consent, and lack of regulation have been identified in contact tracing while some bias-related health inequalities have been highlighted. There is a need for further research focusing on SDOH and these specific AI apps. (shrink)

The increasing application of artificial intelligence (AI) to healthcare raises both hope and ethical concerns. Some advanced machine learning methods provide accurate clinical predictions at the expense of a significant lack of explainability. Alex John London has defended that accuracy is a more important value than explainability in AI medicine. In this article, we locate the trade-off between accurate performance and explainable algorithms in the context of distributive justice. We acknowledge that accuracy is cardinal from outcome-oriented justice because it helps (...) to maximize patients’ benefits and optimizes limited resources. However, we claim that the opaqueness of the algorithmic black box and its absence of explainability threatens core commitments of procedural fairness such as accountability, avoidance of bias, and transparency. To illustrate this, we discuss liver transplantation as a case of critical medical resources in which the lack of explainability in AI-based allocation algorithms is procedurally unfair. Finally, we provide a number of ethical recommendations for when considering the use of unexplainable algorithms in the distribution of health-related resources. (shrink)

Global consumption, production, and trade of livestock products have increased rapidly in the last two decades and are expected to continue. At the same time, safety concerns regarding human and animal disease associated with livestock products are increasing. Efforts to increase public health safety standards aimed at legitimately reducing the risks of human and animal disease have focused internationally on standards to regulate the movement of livestock products. There is concern, though, that measures to regulate these standards internationally, such as (...) the WTO SPS measures that in part aim to open international markets, may marginalize small-scale poor producers. The cycle of poverty they are trying to escape through livestock production may, in fact, widen, leading to increased global poverty, malnutrition, and disease. Developing and developed nations alike should be concerned with public and private efforts to address appropriate food safety policies to reduce the likelihood of this effect. Analysis of the impact on small-scale livestock farmers is needed, as well as solutions that consider joint public and private sector initiatives. Costly farm to table tracking systems are not an option, but locally orchestrated vertically integrated systems may have merit in reducing food safety risks and in providing small-scale farmers with increased access to markets, locally and internationally. Increased scientific and technical capacity, and training of WTO officials from developing nations is also needed. (shrink)

Background Consent policies for post-mortem organ procurement (OP) vary throughout Europe, and yet no studies have empirically evaluated the ethical implications of contrasting consent models. To fill this gap, we introduce a novel indicator of governance quality based on the ideal of informed support, and examine national differences on this measure through a quantitative survey of OP policy informedness and preferences in seven European countries. -/- Methods Between 2017–2019, we conducted a convenience sample survey of students (n = 2006) in (...) Austria (AT), Belgium (BE), Denmark (DK), Germany (DE), Greece (GR), Slovenia (SI) and Spain (ES), asking participants about their donation preferences, as well as their beliefs and views about the policy in place. From these measures, we computed indices of informedness, policy support, and fulfilment of unexpressed preferences, which we compared across countries and consent systems. -/- Results Our study introduces a tool for analyzing policy governance in the context of OP. Wide variation in policy awareness was observed: Most respondents in DK, DE, AT and BE correctly identified the policy in place, while those in SI, GR and ES did not. Respondents in opt-out countries (AT, BE, ES and GR) tended to support the policy in place (with one exception, i.e., SI), whereas those in opt-in countries (DE and DK) overwhelmingly opposed it. These results reveal stark differences in governance quality across countries and consent policies: We found a preponderance of informed opposition in opt-in countries and a general tendency towards support–either informed or uninformed–in opt-out countries. We also found informed divergence in opt-in countries and a tendency for convergence–either informed or uninformed–among opt-out countries. -/- Conclusion Our study offers a novel tool for analyzing governance quality and illustrates, in the context of OP, how the strengths and weaknesses of different policy implementations can be estimated and compared using quantitative survey data.

The ethics of deceased organ procurement (OP) is supposedly based on individual consent to donate, either explicit (opt-in) or presumed (opt-out). However, in many cases, individuals fail to express any preference regarding donation after death. When this happens, the decision to remove or not to remove their organs depends on the policy’s default option or on family preferences. Several studies show that in most countries the family plays a significant and often decisive role in the process of decision-making for OP. (...) Depending on the country, the family may be allowed to take different kinds of actions in different situations, and this may be granted either by law or by clinical practice only. This adds much complexity to the usual classification of consent policies in two categories: opt-in and opt-out. Here we propose a novel and comprehensive taxonomy of the models of consent for OP according to three variables: (1) the deceased’s wishes, if any, (2) family wishes, if any, and (3) default policies. By analysing these models of consent, we show that they rely on at least three different concepts of autonomy: individual autonomy, relational autonomy, and family autonomy. In light of this analysis, we discuss the ethical debates surrounding two policy approaches: presumed consent and family veto. (shrink)

Goal: To assess public knowledge and attitudes towards the family’s role in deceased organ donation in Europe. -/- Methods: A systematic search was conducted in CINHAL, MEDLINE, PAIS Index, Scopus, PsycINFO, and Web of Science on December 15th, 2017. Eligibility criteria were socio-empirical studies conducted in Europe from 2008 to 2017 addressing either knowledge or attitudes by the public towards the consent system, including the involvement of the family in the decision-making process, for post-mortem organ retrieval. Screening and data collection (...) were performed by two or more independent reviewers for each record. -/- Results: Of the 1482 results, 467 studies were assessed in full-text form, and 33 were included in this synthesis. When the deceased has not expressed any preference, a majority of the public support the family's role as a surrogate decision-maker. When the deceased expressly consented, the respondents' answers depend on whether they see themselves as potential donors or as a deceased's next-of-kin. Answers also depend on the relationship between the deceased and the decision-maker(s) within the family, and on their ethnic or cultural background. -/- Conclusions: Public views on the authority of the family in organ donation decision-making require further research. A common conceptual framework and validated well-designed questionnaires are needed for future studies. The findings should be considered in the development of Government policy and guidance regarding the role of families in deceased organ donation. (shrink)

Justo antes de la pandemia por COVID-19, la Organización Mundial de la Salud definió unas prioridades de trabajo para la década 2020-2030. Un grupo interdisciplinario de profesionales de la salud reflexiona sobre estas prioridades, determinando unas categorías de análisis y, desde una perspectiva bioética, analiza cada una de ellas, ve su pertinencia, algunos eventos causales, las implicaciones que pueden tener si no son enfrentadas adecuadamente y hace sugerencias sobre la forma de llevarlas a cabo. En esta primera entrega se analiza (...) el primer grupo de prioridades estratégicas: “poblaciones más sanas”. En las conclusiones se destaca la conveniencia de acometer cada una de ellas de una manera colaborativa, gubernamental y privada; de reestructurar el sector salud con base en estas prioridades, aprovechando la experiencia obtenida en la lucha contra el COVID-19. La relación del ser humano con el medio ambiente también debe cambiar, apelando a la responsabilidad humana por el cuidado del planeta. (shrink)

Currently, the most used method to measure brain activity under a non-invasive procedure is the electroencephalogram (EEG). This is because of its high temporal resolution, ease of use, and safety. These signals can be used under a Brain Computer Interface (BCI) framework, which can be implemented to provide a new communication channel to people that are unable to speak due to motor disabilities or other neurological diseases. Nevertheless, EEG-based BCI systems have presented challenges to be implemented in real life situations (...) for imagined speech recognition due to the difficulty to interpret EEG signals because of their low signal-to-noise ratio (SNR). As consequence, in order to help the researcher make a wise decision when approaching this problem, we offer a review article that sums the main findings of the most relevant studies on this subject since 2009. This review focuses mainly on the pre-processing, feature extraction, and classification techniques used by several authors, as well as the target vocabulary. Furthermore, we propose ideas that may be useful for future work in order to achieve a practical application of EEG-based BCI systems toward imagined speech decoding. (shrink)

The main aim of this article is to reflect on the impact of biases related to artificial intelligence (AI) systems developed to tackle issues arising from the COVID-19 pandemic, with special focus on those developed for triage and risk prediction. A secondary aim is to review assessment tools that have been developed to prevent biases in AI systems. In addition, we provide a conceptual clarification for some terms related to biases in this particular context. We focus mainly on nonracial biases (...) that may be less considered when addressing biases in AI systems in the existing literature. In the manuscript, we found that the existence of bias in AI systems used for COVID-19 can result in algorithmic justice and that the legal frameworks and strategies developed to prevent the apparition of bias have failed to adequately consider social determinants of health. Finally, we make some recommendations on how to include more diverse professional profiles in order to develop AI systems that increase the epistemic diversity needed to tackle AI biases during the COVID-19 pandemic and beyond.

Background: Several countries have recently changed their model of consent for organ donation from opt-in to opt-out. We undertook a systematic review to determine public knowledge and attitudes towards these models in Europe. Methods: Six databases were explored between 1 January 2008 and 15 December 2017. We selected empirical studies addressing either knowledge or attitudes towards the systems of consent for deceased organ donation by lay people in Europe, including students. Study selection, data extraction, and quality assessment were conducted by (...) two or more reviewers independently. Findings: Awareness of the consent model was lower in opt-out countries than in opt-in countries. A majority of the public agrees with opt-in, regardless of the law in their own country. There are ambivalent attitudes regarding the opt-out system. The public tend to prefer opt-in and mandatory choice over opt-out when several options are offered. Interpretation: The assumption that people in opt-out countries are aware of the legal requirements to be excluded from the pool of potential donors is not supported by the results of this review. This is a concern, since ignorance hinders people's autonomy regarding organ donation decision-making. Higher awareness of consent model in opt-in countries may reflect greater efforts to inform the public through campaigns to motivate donation. Legal moves towards opt-out are at odds with people's expressed preferences. Main limitations of this review are the lack of data from some countries, study population heterogeneity, and methodological shortcomings. (shrink)

IntroductionThe prefrontal cortex plays a crucial role in cognition, particularly in executive functions. Cortical reactivity measured with Transcranial Magnetic Stimulation combined with Electroencephalography is altered in pathological conditions, and it may also be a marker of cognitive status in middle-aged adults. In this study, we investigated the associations between cognitive measures and TMS evoked EEG reactivity and explored whether the effects of this relationship were related to neurofilament light chain levels, a marker of neuroaxonal damage.MethodsFifty two healthy middle-aged adults from (...) the Barcelona Brain Health Initiative cohort underwent TMS-EEG, a comprehensive neuropsychological assessment, and a blood test for NfL levels. Global and Local Mean-Field Power, two measures of cortical reactivity, were quantified after left prefrontal cortex stimulation, and cognition was set as the outcome of the regression analysis. The left inferior parietal lobe was used as a control stimulation condition.ResultsLocal reactivity was significantly associated with working memory and reasoning only after L-PFC stimulation. No associations were found between NfL and cognition. These specific associations were independent of the status of neuroaxonal damage indexed by the NfL biomarker and remained after adjusting for age, biological sex, and education.ConclusionOur results demonstrate that TMS evoked EEG reactivity at the L-PFC, but not the L-IPL, is related to the cognitive status of middle-aged individuals and independent of NfL levels, and may become a valuable biomarker of frontal lobe-associated cognitive function.

In recent years, supported by new scientific evidence, the conceptualization of cognitive reserve has been progressively enriched and now encompasses not only cognitive stimulating activities or educational level, but also lifestyle activities, such as leisure physical activity and socialization. In this context, there is increasing interest in understanding the role of psychological factors in brain health and cognitive functioning. In a previous study, we have found that these factors mediated the relationship between CR and self-reported cognitive functioning. In this study, (...) we have confirmed an association between two important constructs included in the psychological wellbeing and salutogenic models, “purpose in life” and “sense of coherence,” CR, as assessed using a questionnaire, and cognitive functioning, as evaluated using a comprehensive neuropsychological battery. Results from 888 middle-aged healthy participants from the Barcelona Brain Health Initiative indicate that both sense of coherence and CR were positively associated with verbal memory, reasoning and attention, working memory, and global cognition. Moreover, the relation between CR and cognitive functioning in the different domains is partially mediated by SoC. When we controlled for brain integrity, introducing into the model neurofilament light chain measures, the mediator role of SoC was confirmed for reasoning and attention and global cognition. However, purpose in life was not associated with cognitive functioning. These results reveal the central role of the SoC construct, which mediates the association between classic CR estimates and cognitive functions, potentially representing a modifiable target for interventions that aim to promote brain health.

Background: The Marathon runners must have the proper technical preparation to reach excellence and to achieve adequate psychological preparation for the race. Against this background, the current study aims to describe the implementation results of a cognitive-behavioral intervention based on psychological skills training for marathon runners.Methods: Fourteen amateur male marathoners with an average age of 30 were trained with various emotional and cognitive control techniques to enhance their performance in competition. Various psychological variables, related to the subjects level of perceived (...) stress, and to qualitative characteristics of their thoughts were measured before and after the target marathon race. Results were analyzed through non-parametric tests for two related samples. The Cohen's d effect size for single-group pretest-posttest repeated measures were also performed.Results: Statistical analysis reveals that, controlling for age and running experience, the intervention decreased significantly the level of perceived stress and the occurrence of negative thoughts before the race, during, and after the race.Conclusion: Training in cognitive control and relaxation techniques, as part of the psychological skills training could determine the quality of performance of marathon runners.

In this research, a sliding mode regulator with sine mapping is suggested for the stabilization of electricity generators being affected by magnet interaction nonlinearities and generator nonlinearities. To reach this goal, our suggested regulator has the following contributions: it starts from the sliding mode regulator with the modifications that the saturation mapping is used to reach a smoother performance instead of the signum mapping, and the sine mapping is applied to reach an upper bound in the proportional gain error, it (...) is used to reach some chosen constant behaviors for the angle position, angle speed, and current in the electricity generators, and its stabilization is ensured based on the Lyapunov approach. We show the simulation of the suggested regulator in two electricity generators. (shrink)

Objectives To increase postmortem organ donation rates, several countries are adopting an opt-out (presumed consent) policy, meaning that individuals are deemed donors unless they expressly refused so. Although opt-out countries tend to have higher donation rates, there is no conclusive evidence that this is caused by the policy itself. The main objective of this study is to better assess the direct impact of consent policy defaults per se on deceased organ recovery rates when considering the role of the family in (...) the decision-making process. This study does not take into account any indirect effects of defaults, such as potential psychological and behavioural effects on individuals and their relatives. -/- Design Based on previous work regarding consent policies, we created a conceptual model of the decision-making process for deceased organ recovery that included any scenario that could be directly influenced by opt-in or opt-out policies. We then applied this model to internationally published data of the consent process to determine how frequently policy defaults could apply. -/- Main outcome measures We measure the direct impact that opt-in and opt-out policies have per se on deceased organ recovery. -/- Results Our analysis shows that opt-in and opt-out have strictly identical outcomes in eight out of nine situations. They only differ when neither the deceased nor the family have expressed a preference and defaults therefore apply. The direct impact of consent policy defaults is typically circumscribed to a range of 0%–5% of all opportunities for organ recovery. Our study also shows that the intervention of the family improves organ retrieval under opt-in but hinders it under opt-out. -/- Conclusions This study may warn policy makers that, by emphasising the need to introduce presumed consent to increase organ recovery rates, they might be overestimating the influence of the default and underestimating the power granted to families.

IntroductionExcitability of the primary motor cortex measured with TMS has been associated with cognitive dysfunctions in patient populations. However, only a few studies have explored this relationship in healthy adults, and even fewer have considered the role of biological sex.MethodsNinety-seven healthy middle-aged adults completed a TMS protocol and a neuropsychological assessment. Resting Motor Threshold and Long-Interval Intracortical Inhibition were assessed in the left motor cortex and related to attention, episodic memory, working memory, reasoning, and global cognition composite scores to evaluate (...) the relationship between cortical excitability and cognitive functioning.ResultsIn the whole sample, there was a significant association between LICI and cognition; specifically, higher motor inhibition was related to better working memory performance. When the sample was broken down by biological sex, LICI was only associated with working memory, reasoning, and global cognition in men. No associations were found between RMT and cognitive functions.ConclusionGreater intracortical inhibition, measured by LICI, could be a possible marker of working memory in healthy middle-aged adults, and biological sex plays a critical role in this association.

Olympic combat sports are unconventional physical activity strategies to train middle-aged and older people with and without health problems. This systematic review aimed to assess the available body of published peer-reviewed articles related to the effects of Olympic combat sports interventions on health-related quality of life in adults aged 45 and older. The search was carried out in five generic databases until July 2021 and the protocol was registered in PROSPERO. The PRISMA guidelines were followed and the Downs and Black (...) checklist was used to assessed the methodological quality of the studies. After reviewing 1,151 records, only seven studies met the inclusion criteria, adding 212 participants with a mean age of 63.7 years. Six studies provided data to calculate the effect size in the Olympic combat sports groups. Three studies reported beneficial changes with a small ES for the total score of the health-related quality of life. Two studies reported a beneficial change with a small ES and strong ES for physical health. One study reported improvements with a small ES for emotional and functional well-being. In conclusion, interventions based on Olympic combat sports produce beneficial effects with a small and moderate ES on health-related quality of life in male and female aged 45 and older who are healthy participants, participants with Parkinson's disease, and participants with breast cancer.Systematic Review Registration:https://www.crd.york.ac.uk/prospero/, PROSPERO: CRD42021244161.

BackgroundResearch on prevalence of cognitive frailty phenotypes in community-dwelling older adults in different countries is important to estimate their prevalence and to determine the influence of cognitive reserve and mental health in order to prevent frailty. The aims of this study were to estimate the prevalence of reversible and potentially reversible cognitive frailty in a Portuguese sample of old adults and explore the associations between these phenotypes and demographic, comorbidity, social support, cognitive reserve and mental health factors.MethodsWe assessed frailty in (...) 250 community-dwelling older adults aged 60 years or over without dementia, neurological or psychiatric disorders. Subjective cognitive decline and Mild cognitive impairment were diagnosed according to standard criteria. The questionnaires Charlson Index, Medical Outcomes Study Social Support, Cognitive Reserve Index and General Health were used for assessing comorbidity, social support, cognitive reserve and mental health, respectively.ResultsPrevalence of R-CF was 14%, and that of PR-CF, 15.2%. Cognitive frailty profiles differed significantly in relation to education, comorbidity, mental health, and cognitive reserve, but not in age or sex. Multivariate logistic regression showed that age, sex, comorbidity, social support, mental health, and cognitive reserve together predicted R-CF and PR-CF with significant OR for mental health and cognitive reserve.DiscussionCognitive reserve and mental health are important factors predicting R-CF and PR-CF. We recommend assessing these factors for early detection of cognitive frailty and promoting psychological well-being and lifestyles that increase cognitive reserve in adults. (shrink)

Background: This research explores how public awareness and attitudes toward donation and transplantation policies may contribute to Spain's success in cadaveric organ donation. Materials and Methods: A representative sample of 813 people residing in Andalusia (Southern Spain) were surveyed by telephone or via Internet between October and December 2018. Results: Most participants trust Spain's donation and transplantation system (93%) and wish to donate their organs after death (76%). Among donors, a majority have expressed their consent (59%), and few nondonors have (...) expressed their refusal (14%). Only a minority are aware of the presumed consent system in force (28%) and feel sufficiently informed regarding the requirements needed to be an organ donor (16%). Participants mainly consider that relatives should represent the deceased's preferences and be consulted when the deceased's wishes are unknown, as is the case in Spain. Conclusion: Public trust in the transplant system may contribute to Spain's high performance in organ donation. High levels of societal support toward organ donation and transplantation do not correspond with similar levels of public awareness of donation and transplantation policies in Spain. (shrink)

This essay is devoted to the study of proper names. Although the view that sees proper names as referential singular terms is widely considered orthodoxy, there is a growing popularity to the view that proper names are predicates. This is partly because the orthodoxy faces two anomalies that Predicativism can solve: on the one hand, proper names can have multiple bearers. But multiple bearerhood is prima facie a problem to the idea that proper names have just one individual as referent. (...) On the other hand, proper names can have predicative uses. But the view that proper names are singular terms arguably does not have the resources to deal with these uses. In this dissertation I argue that the Predicate View of proper names is mistaken. In the first part of the thesis, I analyse this view in its main contentions and offer several arguments to reject it. This critical exercise provides useful insight into the life of proper names that I incorporate in my own view as follows: I argue that the behaviour of proper names should be understood in light of the wider phenomenon I call category change. Thus, I maintain, with orthodoxy, that proper names are fundamentally referential terms, but I also argue that they also have other uses, including the predicative uses highlighted by the predicativist. I also offer a semantic theory according to which proper names are polyreferential, that is, they are terms that can have more than one referent in a way that is distinct from both plural terms and general terms. This theory resolves the problem of multiple bearerhood and provides a base to account for all other uses of proper names that are not referential, i.e., common noun, adjectival and verbal uses, as semantically derived from the more fundamental referential meaning.

In this piece of work we considerer mathematical logic as a whole. The three steps distinguished by Husserl, to wit, pure logic grammar, logic of the non-contradiction and logic of the truth, are analysed. They are applied to the logistics by distinguishing different levels and layers. In each level the logistics methods and its correspondence with the formal ontology inside the philosophical phenomenology are taken into account. The subject is completed explaining the axiomatic as well as the Greek life in (...) Euclides and in comparison with Hilbert. Finally, we intend to interpret the Greek logic, Leibniz logic and logistics from the viewpoint of different types of life related to them. In all these cases we presuppose, as a source, the apofantic aristotelian form of the proposition. (shrink)

Este artículo discute la cercana relación entre la teología y la filosofía natural de Newton. Tomando como punto de inscripción el ejemplo de la Óptica, se refutarán estas lecturas de Newton. Primero, se examinará la evidencia que muestra que Newton contempló una declaración explícita de filosofía natural para la primera edición de la Óptica. Luego se discutirá el material teológico-natural añadido a la Optice de 1706. Al hacerlo, se señalarán ejemplos de su relación con las afirmaciones hechas en el Escolio (...) General de los Principia, se demostrará cómo éste está iluminado por las afirmaciones más explícitas hechas en un borrador a la Cuestión 23 (31), y se explorarán conexiones entre las declaraciones públicas de las Cuestiones y material más explícito sobre teología natural en los manuscritos privados de Newton. Luego se mostrará que, así como en el Escolio General, el material añadido a las ediciones posteriores de la Óptica también incluye claves sobre su teología antitrinitaria herética. Finalmente, se sugerirán formas en que los compromisos de Newton con la teología natural, y un poderoso Dios unitario del dominio, ayudaron a sustentar su filosofía natural. En suma, este artículo sostiene que la teología natural de Newton y su teología herética se relacionan con la filosofía natural de la Óptica de maneras que son mucho más fundamentales que un delgado barniz de retórica. Este artículo se basa no sólo en un análisis de los textos publicados, sino también de los borradores relacionados con la Óptica y otros paralelos textuales en los escritos inéditos de Newton. Estos manuscritos privados ayudarán a abrir una ventana en el sentido que buscaban los textos públicos de Newton. (shrink)

Cybernetics is a science characterized by the utopian search for new relationships between different areas of knowledge. After the Second World War, the best-known references in Western academia were Norbert Wiener’s approaches to this new discipline. However, there is another little-known hemisphere of this development that remains understudied and we claim is key for its history which refers to the pioneering work of scientists, engineers and cultural practitioners in Latin America, as well as the materialization of specific experiences that lead (...) us to reflect on the role that some regional milestones could have had in the global context. This volume of AI & Society covers points of view that were structured in the various most emblematic stages of these trajectories with the participation of agents that went beyond the assimilation and interpretation of external models, transforming themselves into fundamental and pioneering experiences, among others, the work of Mexican scientist Arturo Rosenblueth, or the impact of the concept of Autopoiesis. Through this article we introduce the outcome of the research—presented in great length in the contributions of this volume—on some of the main stages and trends that constituted the evolution of cybernetics in Latin America. The particular contributions of the authors in this issue have helped to reconstituting these contexts while developing a continuous horizon which also explores future practices. (shrink)

El presente trabajo elucida el axioma de “la pluralidad necesaria” a partir de algunas calas y notas del pensamiento de Judith Butler y algunos cruces procedentes de la filosofía de Michel Foucault y Friedrich Nietzsche, así como el influjo postnietzscheano contemporáneo, en contraste con el pensamiento mestizo subalterno latinoamericano de Gloria Anzaldúa. La hipótesis central es explicada en estos términos: no existe ningún fundamento metafísico que sustente al mundo; todo es una construcción cultural, resultado del poder predominante en un determinado (...) contexto histórico. El poder es el que establece lo que es normal o anormal, lo que está permitido o no está permitido. En este contexto, se postula la necesidad de someter a los dispositivos de poder reinantes, en las sociedades contemporáneas, bajo una revisión crítica que permita transformarlos en dispositivos de poder que hagan posible sociedades plurales e incluyentes. Y justo aquí, en la apertura de un nuevo horizonte postmetafísico y post-humanista es retomada la perspectiva mestiza subalterna de Gloria Anzaldúa como una forma radical de repensar la condición humana más allá del euro-logo-falocentrismo desde los márgenes de América Latina. La pluralidad necesaria, lejos de ser un título contradictorio, es, antes bien, un título que expresa una afirmación, a saber, la necesidad de una realidad social plural, inclusiva, en la que las diferencias entre los seres humanos sean respetadas, siguiendo el ideal de una sociedad democrática en la que se cultive la apertura a los otros, en un ambiente de convivencia y diálogo.

In this book, which thoroughly revises and greatly expands his classic work Sameness and Substance, David Wiggins retrieves and refurbishes in the light of twentieth-century logic and logical theory certain conceptions of identity, of substance and of persistence through change that philosophy inherits from its past. In this new version, he vindicates the absoluteness, necessity, determinateness and all or nothing character of identity against rival conceptions. He defends a form of essentialism that he calls individuative essentialism, and then a (...) form of realism that he calls conceptualist realism. In a final chapter he advocates a human being-based conception of the identity and individuation of persons, arguing that any satisfactory account of personal memory must make reference to the life of the rememberer himself. This important book will appeal to a wide range of readers in metaphysics, philosophical logic, and analytic philosophy. (shrink)

Las artes visuales, marginadas de otras áreas del conocimiento, por la fragmentación epistemológica propi-ciada por el positivismo y con afán de responder al desarrollo vertiginoso y complejo de nuevas tecnologías, han perdido la más importante de sus tareas, la reflexión. La especulación sobre la acción artística y la entrega de juicios críticos acerca de sus manifestaciones implica la introspección y el pensar sobre sus procesos y parámetros de desarrollo. Imaginar y crear en las artes visuales se ha convertido en las (...) reacciones espontáneas resultantes de la intuición del instante, olvidando etapas importantes de concentración, abstracción, especulación y transformación de la experiencia estética. Hoy las artes son la provocación de una cadena de reacciones físicas: repulsión, sorpresa, rechazo, etc., de las transgresiones a la forma y no al fondo, hay un abismo entre el pensamiento y la razón. Hay un olvido de los contenidos, por los que lucharon Klee, Kandinsky, Arnheim o Gombrich y que hizo comprensible la obra de Cézanne, Duchamp o Beuys. Se trata de una reflexión sobre la importancia del dominio epistemológico en las artes visuales, una llamada a regresar a su conceptualización y a reconstruir la filosofía y la teoría del arte visual de nuestro tiempo. Estas disciplinas tienen un aspecto teórico referente a los conceptos que las sustentan, un aspecto técnico concerniente a los medios por los cuales se crea la obra o la acción artística y un aspecto poético, que establece un nexo entre quien crea la obra y quienes la perciben y contemplan, éstos entre sí y entre éstos y la obra. Lo anterior requiere de los conocimientos indis-pensables para reconocer y comprender tanto el excedente de sentido de las artes visuales como la socialización sus valores culturales, son indispensables las estructuras y concepciones teóricas porque, de un mismo objeto o acción se dan diversas interpretaciones igualmente válidas, siempre y cuando estén sustentadas cognoscitivamente. Las artes visuales son una unidad de saber, un conjunto de conocimientos unificados merced a ciertos principios, pero no es un cuerpo de verdades cerradas, al contrario, se hallan en relación permanente y dinámica con otros ámbitos cognoscitivos, influyen en algunos y son influenciadas por otros. La conceptuación de las artes visuales es valiosa porque tiene efectos directos en la forma de pensamiento, en la conducta y en las acciones y decisiones de los seres humanos, en virtud de que se conciben como generadoras de valores y bienes culturales.

Lipsey and Lancaster's "general theory of second best" is widely thought to have significant implications for applied theorizing about the institutions and policies that most effectively implement abstract normative principles. It is also widely thought to have little significance for theorizing about which abstract normative principles we ought to implement. Contrary to this conventional wisdom, I show how the second-best theorem can be extended to myriad domains beyond applied normative theorizing, and in particular to more abstract theorizing about the normative (...) principles we should aim to implement. I start by separating the mathematical model used to prove the second-best theorem from its familiar economic interpretation. I then develop an alternative normative-theoretic interpretation of the model, which yields a novel second best theorem for idealistic normative theory. My method for developing this interpretation provides a template for developing additional interpretations that can extend the reach of the second-best theorem beyond normative theoretical domains. I also show how, within any domain, the implications of the second-best theorem are more specific than is typically thought. I conclude with some brief remarks on the value of mathematical models for conceptual exploration. (shrink)

En esta entrevista se formularon preguntas al magíster Iván Martínez, docente universitario destacado por sus conocimientos especializados en infraestructuras de redes y por sus múltiples participaciones en eventos académicos.

En la conversación se llega a comprender cuál es su utilidad y cómo esta puede servir al usuario en distintos ámbitos, como el laboral. Por otro lado, el (...) ingeniero de Sistemas concluye con el modo en que sus saberes son transferidos a sus alumnos con mucha prerrogativa. (shrink)

Artificial intelligence has historically been conceptualized in anthropomorphic terms. Some algorithms deploy biomimetic designs in a deliberate attempt to effect a sort of digital isomorphism of the human brain. Others leverage more general learning strategies that happen to coincide with popular theories of cognitive science and social epistemology. In this paper, I challenge the anthropomorphic credentials of the neural network algorithm, whose similarities to human cognition I argue are vastly overstated and narrowly construed. I submit that three alternative supervised learning (...) methods—namely lasso penalties, bagging, and boosting—offer subtler, more interesting analogies to human reasoning as both an individual and a social phenomenon. Despite the temptation to fall back on anthropomorphic tropes when discussing AI, however, I conclude that such rhetoric is at best misleading and at worst downright dangerous. The impulse to humanize algorithms is an obstacle to properly conceptualizing the ethical challenges posed by emerging technologies. (shrink)

El objetivo de este trabajo es analizar los ejemplos que se dan en las obras tradicionales del denominado καί estructural con el fin de determinar sus características desde una perspectiva más actual. Este es uno de los tipos de καί adverbial que se distinguen, pero, como veremos, se trata de una categoría compleja en la que, sobre la base de su aparición en una oración subordinada, se han mezclado al menos tres usos más o menos habituales de καί adverbial: aditivo, (...) identificativo y corresponsivo. The aim of this paper is to analyse the examples of the so-called structural καί from a modern perspective. The examples are taken from the traditional grammars, in which this adverbial use of καί is usually distinguished. As it will be shown, this is in fact a complex category, established on the basis of its appearance in a subordinate clause and including three quite common uses of adverbial καί: additive, identificational and corresponsive.

Drawing on work of the past decade, this volume brings together articles from the philosophy, history, and sociology of science, and many other branches of the biological sciences. The volume delves into the latest theoretical controversies as well as burning questions of contemporary social importance. The issues considered include the nature of evolutionary theory, biology and ethics, the challenge from religion, and the social implications of biology today (in particular the Human Genome Project).

A collection of 14 essays honoring the life and work of Oxford philosopher Wiggins touching on topics from ancient philosophy to ethics, metaphysics and the theory of meaning. The contributing scholars debate many of the seminal issues of Wiggins' work, including the determinancy of distinctness, relative identity, naturalism in ethics, logic and truth in moral judgments, and the practical wisdom of Aristotle. The collection uniquely features replies by Wiggins to each of the papers. Annotation copyright by Book News, Inc., Portland, (...) OR. (shrink)
