The principle of conservation of energy tells us that ‘energy can neither be created nor destroyed but only transformed’. The validity of the principle is without question. The problem is the concept. Contemporary physicists have asserted that we do not know what energy is. We find, however, 19th century physicists, contemporary physicists and historians of science who converge on the point: Mayer and Joule discovered energy. Therefore, we do not know what energy is, but we know these authors discovered it. (...) What did they then discover? What can we learn from this with regard to the energy concept problem? To deal with this issue, I will distinguish between what the authors did experimentally and what they said about the phenomena. This method of analysis makes the difference in relation to historical works on the subject. In a second step, I will consider the introduction of the energy concept, which is from 1850s, and the reification of the energy in 1880s. Finally, I will address the energy conservation principle and the concept of energy conveyed by this principle in contemporary textbooks. As we shall see, the conservation of a magnitude that we call energy nowadays was discovered by Mayer and Joule; an indestructible and transformable entity was not. Adopting the original conservation principle would be enough to avoid the energy concept problem. (shrink)

The present comment on Solari and Natiello’s paper values their constructivist approach to Newtonian Mechanics. My critical point concerns only the link between the concept of force and phenomena. It will be shown that the idealised form of the law of inertia created by the authors avoids criticism of the law and that this law leads to the concept of force as the cause of acceleration. This concept appears in the authors’ reconstruction as an assumption. They add that this assumption (...) must be contrasted with experiments. Following this, I address an experiment, in which the force that is taken as the cause of acceleration, is not present in the phenomenon at stake. As it thus does not satisfy the property of locality, which any cause has to, force cannot be a cause. (shrink)

Philosophers have disagreed on the composition of force for decades. The main divergence concerns the fundamental question: given a certain motion that is observable, which force or forces are present in it, component or resultant forces? The present paper focuses on the conditions for dealing with this problem. I will argue that we are not able to infer force from the observation of a motion, as required by the problem. I will further argue that the validity of the Newtonian algorithm (...) is not a sufficient condition for that inference because the Gaussian algorithm, which is equally valid, differs from the former with regard to the forces present in motions. Under these circumstances, I will make recourse to an experiment available in physics in which the force present in a motion is measured. Thus, we obtain a numerical value for this force. This result, playing the role of a counterexample, clarifies the composition of force issue significantly. (shrink)

This book provides a solution to the problem with the energy concept. This problem manifests itself in the fact that physicists clearly diverge regarding the question of what energy is. Some define it but others state that we do not know what it is. Although this is a problem for physicists who need to explain the concept, it is not a problem for physics that can be solved by laboratory means. Penetrating into the origin of the notion of energy, this (...) book offers a clear idea of what was discovered and what was invented to interpret the findings. Following the development of the concept, it provides an explanation of the trends in contemporary textbooks. The author's repetition, in his "History and Philosophy of Physics Laboratory", of Joule’s famous experiment – the paddle wheel experiment – with a calorimeter as originally used by Joule and with a calorimeter as proposed in textbooks, is presented, yielding new insight into the phenomenon. Thus, science teachers and students will benefit from reading the book as well as historians, philosophers, students of the history and philosophy of science, and all who are interested in knowing about what it is that we call energy.

The development of neuropsychological assessment methods using virtual reality (VR) is a valid and promising option for the detection of cognitive impairment in the older people, focusing on activities composed of tasks of multiple demands. This study verified the association of age, schooling, and general cognitive status on the performance of neurologically healthy older adults in ECO-VR, a virtual reality task of multiple demands for neuropsychological assessment. A total of 111 older adults answered a sociodemographic questionnaire, the Mini Mental State (...) Examination, the Vocabulary subtest of the Wechsler Intelligence Scale for Adults (third edition), and the ECO-VR. Correlation analyses, multiple linear regression, and comparisons between groups (effects by age and schooling groups) were used to evaluate the results. The ECO-VR total score was significantly associated with age, years of education, MMSE, and Vocabulary subtest. The linear regression models identified that age was the main predictor for total score and rule breaking of ECO-VR. According to the univariate analysis, it was identified the main effect of age group and schooling group in the total ECO-VR score, but there was no interaction effect. The results are discussed in order to understand the role of sociodemographic characteristics in the performance of older adults in a virtual reality task of multiple demands. It was also verified the possibility use of virtual reality for neuropsychological assessment of older adults. (shrink)

O presente artigo compõe-se de três partes: filosofia, imagem e literatura. Na primeira, o autor esclarece o conceito de imagem nos Princípios de Mecânica de Heinrich Hertz (1857-1894) através das suas conexões com os conceitos de sistema e de modelo. Aqui se mostra de que modo uma teoria física deve ser entendida como uma imagem construída por nós. Na segunda parte do artigo, aborda-se a teoria física de Hertz em função do conceito de imagem: primeiramente, os fundamentos, incluindo a sua (...) relação à experiência; segundo, a dedução, que é um trabalho de imaginação; finalmente, como se testam os resultados da dedução. O artigo demonstra de que modo o estudo conjugado da filosofia e da física de Hertz permite ultrapassar dificuldades e mal-entendidos na literatura acerca da sua obra, facto de que se dá conta sobretudo na terceira parte do artigo. Em questão estão sobretudo os conceitos de imagem (Bild), exposição da imagem (Darstellung), espaço, partícula de massa, força e aplicação da teoria mecânica. De relevar ainda é o facto de estes assuntos serem também de grande interesse para um aprofundamento do nosso conhecimento da obra de Ludwig Wittgenstein, sobretudo na sua primeira fase. /// The present article consists of three parts: philosophy, image and literature. In the first one the pivotal concept of image in Heinrich Hertz's Principles of Mechanics 15 investigated through its connections with the concepts of system and model. It is shown that a physical theory is an image formed by us. In the second part of the article, Hertz's mechanics is presented as an image: firstly, the fundaments, where their relationship to experiments is dealt with; secondly, the deduction, which is work of imagination; finally, how to test the results of the deduction. The study of the philosophical and physical part of Hertz's Principles together illuminates typical misunderstandings and problems of interpretation of the Principles, as will be seen in the third part of the article. This concerns the concepts of image (Bildj, presentation of the image (Darstellung), space, mass-particle, force and the application of the theory. The subjects clarified in this article are also of interest for a deepening of our understanding of Wittgensteins early work. (shrink)

A Mecânica clássica parte da lei de inércia e usa um conceito de força que é consequência lógica da lei (§ 2-3). Acontece porém que nem a lei de inércia tem fundamento experimental (§ 1) nem o conceito de força tem referente nos fenómenos (§ 4). O estudo da função da lei e da força nas teorias mecânicas veio mostrar que a lei de inércia expressa apenas um movimento unidade e a força desvios à unidade (§ 5). Segue-se que a (...) ciência praticava uma metodologia, mas expressava-se como possuindo um conhecimento dos meandros da natureza. Isto coloca pelo menos uma questão à filosofia, porquanto a caracterização da ciência pela epistemologia usual se mostra inadequada para a mecânica. /// The classical mechanics assumes the law of inertia and uses a concept of force that is a logical consequence of the law (§ 2-3). As a matter of fact the law of inertia has no experimental basis (§ 1) and beyond that the concept of force does not correspond to anything in the mechanical phenomena (§ 4). The study of the structure of the mechanical theories has shown that the law of inertia expresses only a reference motion and the force represents deflections from that motion (§ 5). Therefore it can be concluded that even though science seems to have a far reaching knowledge of nature, it has indeed only practiced a methodology. This poses a problem for the philosophy insofar as it makes the usual epistemological framework inadequate to characterize mechanics. (shrink)

Between 1221 and 1236, Jordan of Saxony, the general master of the Order of Friars Preachers, and Diana Andaló, nun of the monastery of St. Agnes in Bologna, were frequent correspondents. From the exchange of epistles that characterized their friendship, only a few dozen letters written by the friar reached us. In them we can see the growth of the Order in those early years of its institution, its gradual organization as well as the policy of the master in relation (...) to women's religious life, among allusions to the details of everyday life of a religious in the thirteenth century. It is in this documentary corpus that we support ourselves to comprehend the power relations which guided the process of institutionalization of the newly created Order of Friars Preachers, specially the affiliation of women's houses to the Order, a subject on which the friars oscillated between resistance and acceptance, because of the material and administrative implications that such an association meant. We will focus, in the discursive analysis, in three cards - two sent to Diana, and one sent to the provincial of Lombardy, Stephen of Spain - to understand the issues involved in the formation of a women's branch of the Order. We can conclude that this specific discussion comprehended a much bigger cenary of internal disputes for the control of the Order. (shrink)

This paper presents an ontological perspective that enables evaluating the effectiveness of business models from an integrative worldview. Different groups’ fragmented and reductionist views on this topic create a dichotomy that makes it difficult to compare and analyze them in practice. Such groups use different values for some components, which may result in neglecting others and their interrelationship. This study discusses a functional characteristic of business models that academia still needs to address. It explores new frontiers in the field, such (...) as business models for networks, sustainability, and their practical evaluation. To achieve an integrative ontology and avoid focusing on specific constructs or systems at the expense of others, we draw upon the theory of worldviews from Wilhelm Dilthey, reformational philosophy, and Herman Dooyeweerd’s theory of modal aspects. Society should move beyond dualistic thinking and embrace practical and applicable solutions. To help companies develop effective models, we introduce a new business model framework based on an integrative worldview that enables comparisons and evaluations of companies in practice. Creating competitive advantages and value appropriations synergizes with essential aspects of reformational philosophy. Analyzing and interrelating such elements are fundamental to understanding the real applied value of business models. (shrink)

http://dx.doi.org/10.5007/1808-1711.2012v16n1p1 A teoria darwinista tem contribuído para a discussão de problemas nos mais diversos campos filosóficos, entre os quais se inclui a ética e a teoria moral. A sociobiologia e a psicologia evolucionista elucidaram muitos aspectos do comportamento social de diversas espécies animais, a partir de mecanismos como a seleção de parentesco e o altruísmo recíproco que, contudo, são insuficientes para explicar a cooperação no caso humano. Como alternativa, a teoria da dupla herança busca explicar o comportamento humano considerando tanto (...) a biologia quanto as ciências sociais. Segundo esta abordagem, a psicologia social humana é caracterizada por instintos sociais tribais e marcadores simbólicos, que resultam em uma mente que pressupõe princípios morais inatos e universais, selecionados para a vida em grupos orientados por normas sociais, mas que são plasticamente moldados à realidade cultural de cada sociedade.

With respect to De Dreu and Gross's article, we comment on the psychological functions for attack and defense, focusing on associations between individual differences in psychopathic personality traits and the behavioral patterns observed in attack-defense conflicts. We highlight the dimensional nature of psychopathy and formulate hypothetical associations between distinct traits, their different behavioral outcomes, and associated brain mechanisms.

This essay argues that Callicles is depicted by Plato in the Gorgias as a potential tyrant from a psychological standpoint. To this end I will contend that the Calliclean moral psychology sketched at 491e-492c points towards the analysis of the tyrannical individual pursued by Plato in books VIII and IX of the Republic based upon the tripartite theory of the soul. I will thereby attempt to show that (i) in the Gorgias, Callicles does not actually personify the ideal of the (...) superior person advocated by himself insofar as he is still susceptible to shame, as evinced by Socrates' cross-examination (494c-495a); and that (ii) looking forward to the Republic, he can be understood for this same reason as being precisely on the threshold between the democratic and the tyrannical soul.

Establishing the basic knowledge, methodology, and technology for a framework for the continuous decoding of hand/arm movement intention was the aim of the ERC-funded project “Feel Your Reach”. In this work, we review the studies and methods we performed and implemented in the last 6 years, which build the basis for enabling severely paralyzed people to non-invasively control a robotic arm in real-time from electroencephalogram. In detail, we investigated goal-directed movement detection, decoding of executed and attempted movement trajectories, grasping correlates, (...) error processing, and kinesthetic feedback. Although we have tested some of our approaches already with the target populations, we still need to transfer the “Feel Your Reach” framework to people with cervical spinal cord injury and evaluate the decoders’ performance while participants attempt to perform upper-limb movements. While on the one hand, we made major progress towards this ambitious goal, we also critically discuss current limitations. (shrink)

BackgroundThere is evidence that direct journal endorsement of reporting guidelines can lead to important improvements in the quality and reliability of the published research. However, over the last 20 years, there has been a proliferation of reporting guidelines for different study designs, making it impractical for a journal to explicitly endorse them all. The objective of this study was to investigate whether a decision tree tool made available during the submission process facilitates author identification of the relevant reporting guideline.MethodsThis was (...) a prospective 14-week before–after study across four speciality medical research journals. During the submission process, authors were prompted to follow the relevant reporting guideline from the EQUATOR Network and asked to confirm that they followed the guideline (‘before’). After 7 weeks, this prompt was updated to include a direct link to the decision-tree tool and an additional prompt for those authors who stated that ‘no guidelines were applicable’ (‘after’). For each article submitted, the authors’ response, what guideline they followed (if any) and what reporting guideline they should have followed (including none relevant) were recorded.ResultsOverall, 590 manuscripts were included in this analysis—300 in the before cohort and 290 in the after. There were relevant reporting guidelines for 75% of manuscripts in each group; STROBE was the most commonly applicable reporting guideline, relevant for 35% (n = 106) and 37% (n = 106) of manuscripts, respectively. Use of the tool was associated with an 8.4% improvement in the number of authors correctly identifying the relevant reporting guideline for their study (p < 0.0001), a 14% reduction in the number of authors incorrectly stating that there were no relevant reporting guidelines (p < 0.0001), and a 1.7% reduction in authors choosing a guideline (p = 0.10). However, the ‘after’ cohort also saw a significant increase in the number of authors stating that there were relevant reporting guidelines for their study, but not specifying which (34 vs 29%; p = 0.04).ConclusionThis study suggests that use of a decision-tree tool during submission of a manuscript is associated with improved author identification of the relevant reporting guidelines for their study type; however, the majority of authors still failed to correctly identify the relevant guidelines.

CYBATHLON is an international championship where people with severe physical disabilities compete with the aid of state-of-the-art assistive technology. In one of the disciplines, the BCI Race, tetraplegic pilots compete in a computer game race by controlling an avatar with a brain-computer interface. This competition offers a perfect opportunity for BCI researchers to study long-term training effects in potential end-users, and to evaluate BCI performance in a realistic environment. In this work, we describe the BCI system designed by the team (...) Mirage91 for participation in the CYBATHLON BCI Series 2019, as well as in the CYBATHLON 2020 Global Edition. Furthermore, we present the BCI’s interface with the game and the main methodological strategies, along with a detailed evaluation of its performance over the course of the training period, which lasted 14 months. The developed system was a 4-class BCI relying on task-specific modulations of brain rhythms. We implemented inter-session transfer learning to reduce calibration time, and to reinforce the stability of the brain patterns. Additionally, in order to compensate for potential intra-session shifts in the features’ distribution, normalization parameters were continuously adapted in an unsupervised fashion. Across the aforementioned 14 months, we recorded 26 game-based training sessions. Between the first eight sessions, and the final eight sessions leading up to the CYBATHLON 2020 Global Edition, the runtimes significantly improved from 255 ± 23 s to 225 ± 22 s, respectively. Moreover, we observed a significant increase in the classifier’s accuracy from 46 to 53%, driven by more distinguishable brain patterns. Compared to conventional single session, non-adaptive BCIs, the inter-session transfer learning and unsupervised intra-session adaptation techniques significantly improved the performance. This long-term study demonstrates that regular training helped the pilot to significantly increase the distance between task-specific patterns, which resulted in an improvement of performance, both with respect to class separability in the calibration data, and with respect to the game. Furthermore, it shows that our methodological approaches were beneficial in transferring the performance across sessions, and most importantly to the CYBATHLON competitions. (shrink)

This article is the lead piece in a special report that presents the results of a bioethical investigation into chimeric research, which involves the insertion of human cells into nonhuman animals and nonhuman animal embryos, including into their brains. Rapid scientific developments in this field may advance knowledge and could lead to new therapies for humans. They also reveal the conceptual, ethical, and procedural limitations of existing ethics guidance for human‐nonhuman chimeric research. Led by bioethics researchers working closely with an (...) interdisciplinary work group, the investigation focused on generating conceptual clarity and identifying improvements to governance approaches, with the goal of helping scholars, funders, scientists, institutional leaders, and oversight bodies (embryonic stem cell research oversight [ESCRO] committees and institutional animal care and use committees [IACUCs]) deliver principled and trustworthy oversight of this area of science. The article, which focuses on human‐nonhuman animal chimeric research that is stem cell based, identifies key ethical issues in and offers ten recommendations regarding the ethics and oversight of this research. Turning from bioethics’ previous focus on human‐centered questions about the ethics of “humanization” and this research's potential impact on concepts like human dignity, this article emphasizes the importance of nonhuman animal welfare concerns in chimeric research and argues for less‐siloed governance and oversight and more‐comprehensive public communication.

The question "what is art?" is often said to be venerable and vexing. In fact, the following answer to the question should be obvious: (R) item x is a work of art if and only if x is a work in practice P and P is one of the arts. Yet (R) has appeared so far from obvious that nobody has given it a moment's thought. The trouble is not that anyone might seriously deny the truth of (R), but rather (...) that they will find it uninformative. After all, the vexing question is pressed upon us by radical changes in art of the avant-garde, and (R) offers no resources to address these changes. With that in mind, here is the case for (R). The challenges posed by the avant-garde are real enough and they need to be addressed, but the vexing question is the wrong question to ask to address them. It does not follow that the question has no good answer. On the contrary, (R) is all the answer we need, if we do not need an answer that addresses the challenges posed by the avant-garde. Moreover, (R) points to a question that we do need answered. So, not only is it true but, in addition, (R) is as informative as we need. (shrink)

Review of Quinália, R. _O Belo em Platão_.

ContextPeople with mental disorders can acquire long-term disabilities, which could impair their functioning and quality of life (QoL), requiring permanent care and social support. Systematic data on QoL and functioning, which could support a better management of these people, were not available.ObjectiveTo analyze the QoL, level of functioning and their association with sociodemographic and clinical factors of people with mental disorders who underwent deinstitutionalization using assisted living facilities.MethodsA Cross-sectional study was conducted between July 2018 and July 2019, through interviews using (...) the World Health Organization Quality of Life (WHOQOL-BREF) to determine the QoL scores, and the World Health Organization Disability Assessment Schedule (WHODAS 2.0) to determine the level of functioning. All adults (≥18 years old) with mental disorders, who underwent deinstitutionalization, users of assisted living facilities and assisted by the Psychosocial Assistance Centers III, in a city in the state of São Paulo, Brazil, were selected. For statistical analysis of the associated factors, Student’st-test was used for dichotomous variables and ANOVA for polynomial variables. Pearson correlation coefficient was used to measure the association between QoL and functioning scores.ResultsOut of 359 people who underwent deinstitutionalization with mental disorders, 147 met the eligibility criteria. The mean total score for the WHOQOL-BREF was 66.5 ± 13.4 and the mean score for WHODAS 2.0 was 10.4 ± 7.6. An association was found between people who were studying (n= 65.8; 95%CI, 63.5–68.1vs. n= 73.9; 95%CI, 67.5–80.3;p= 0.04) and better WHOQOL-BREF QoL scores or WHODAS 2.0 levels of functioning (n= 10.9; 95%CI, 9.6–12.2vs. n= 5.1; 95%CI, 2.5–7.7;p= 0.01). A weak negative correlation (r= 0.41) emerged between higher QoL scores and functioning improvement.ConclusionThis study indicates that the QoL of the sample is associated by their functioning levels, which, in turn, may reflect on their social interactions. Public policies that favor interventions increasing socialization of this population can result in better health outcomes. The QoL and functioning scores provide valuable insights to develop public policies more suited to this population profile. (shrink)

In The Value Gap, Toni Rønnow-Rasmussen addresses the distinction between what is finally good and what is finally good-for, two value notions that are central to ethics and practical deliberation. The first part of the book argues against views that claim that one of these notions is either faulty, or at best conceptually dependent on the other notion. Whereas these two views disagree on whether it is good or good-for that is the flawed or dependent concept, it is argued, as (...) against both approaches, that goodness and goodness-for are independent value notions that cannot be fully understood in terms of one another. The second part provides an analysis of good and good-for in terms of a fitting-attitude analysis. By elaborating a more nuanced understanding of the key elements of this analysis—reasons and pro-attitudes—Rønnow-Rasmussen challenges the widespread idea that there are no genuine practical and moral dilemmas. The result is that the gap between favouring for a reason what is good and favouring for a reason what is good for someone appears insurmountable. (shrink)

In the 1930s, the Bengali philosopher K. C. Bhattacharyya proposed a new theory of rasa, or aesthetic emotion, according to which aesthetic emotions are feelings that have other feelings as their intentional objects.

I defend Kant’s definition of analyticity in terms of concept “containment”, which has engendered widespread scepticism. Kant deployed a clear, technical notion of containment based on ideas standard within traditional logic, notably genus/species hierarchies formed via logical division. Kant’s analytic/synthetic distinction thereby undermines the logico-metaphysical system of Christian Wolff, showing that the Wolffian paradigm lacks the expressive power even to represent essential knowledge, including elementary mathematics, and so cannot provide an adequate system of philosophy. The results clarify the extent to (...) which analyticity sensu Kant can illuminate the problem of a priori knowledge generally. (shrink)

Nietzsche’s perspectivism has received restricted and unrestricted interpretations. The latter take the cognitive effects of ‘perspectives’ to be pervasive and general; the former argue they are restricted to special subject matters, have limited effects, or are not essentially cognitive at all. I argue on textual grounds that Nietzsche was committed to the unrestricted view. Comparison to A.W. Moore’s treatment of perspectival representation in Points of View illuminates both the nature of perspectivism and key arguments needed to defend it. Nietzschean perspectivism (...) must deny the very possibility of absolute representations (sensu Moore), and to do so, it must block a form of argument that promises to integrate perspectival representations into progressively less restricted, and ultimately absolute, representations of the world. Such arguments depend on a strong assumption about the unity of the independent world, which Moore accepts and Nietzsche denies. Nietzsche’s pluralism about perspectives thereby turns out to rely on pluralism about the world, which shapes his understanding of us as essentially bounded cognitive agents. Nietzsche holds that the longing for absolute representation manifest in Moore, Leibniz, and many other philosophers, which aspires to overcome the limitations of perspective, amounts to ascetic self-denial about our cognitive condition.
