O artigo busca sustentar a tese de que W. Mignolo não consegue realizar seu principal objetivo: romper com padrões eurocêntricos na produção de conhecimento. Para atingir tal fim, o método empregado foi a análise imanente do livro “On Decoloniality” (2018). Foi proposto que o afastamento pretendido pelo autor não se efetiva, uma vez que sua teoria do conhecimento e solução epistemológica se configuram como uma renovação da filosofia da vida da fase imperialista. Com isso, Mignolo e sua “epistemologia de fronteiras” (...) reproduzem os aspectos essenciais daquela tendência do pensamento burguês. (shrink)

Introduction: The actions taken by the government to deal with the consequences of the coronavirus diseases 2019 pandemic caused different levels of restriction on the mobility of the population. The need to continue offering physical exercise to individuals after stroke became an emergency. However, these individuals may have barriers to adhere to the programs delivered remotely. There is a lack of evidence related to adherence, attendance, safety, and satisfaction of remote exercise programs for this population.Objective: The aim was to evaluate (...) adherence and barriers to attend a remote physical exercise program for individuals after stroke. We aimed to identify adherence and attendance rate of the remote physical exercise program ; to identify the safety of a remote physical exercise program ; and to identify the overall experience to participate in a remote program.Materials and methods: This is a longitudinal study, including 36 stroke survivors who already attended a face-to-face physical exercise program prior to the COVID-19 pandemic. The remote physical exercise program included sessions for 2 days/week for a duration of 22 weeks, with a total of 44 sessions, which were delivered asynchrony via recorded video sessions. As outcome measures, we performed two questionnaires to identify attendance, barriers, safety, and overall experience related to the program.Results: The adherence rate was 86. The attendance rate was 19, with a total of 8 sessions. The main barriers for lower attendance rate were as follows: lack of motor skills and physical fitness to workout in 80 reports, followed by no exercise companion in 44 reports. The remote physical program has been shown to be safe, and the overall experience was positive from the perspectives of the participants and the family members.Conclusion: Although the adherence rate was high, the attendance rate was low on the remote physical exercise program. The main barriers to attending the program remotely reflect the need of tailoring individually an asynchrony mode of delivering the sessions to individuals after stroke. Our results also indicate how the COVID-19 impacted the health conditions of stroke survivors. The program was safe, and the overall experience indicated a change in the mental, physical, and social health of individuals after stroke and their family members. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:preface This issue of Feminist Studies includes a cluster of essays that demonstrates new approaches to life writing, with special attention to unconventional women’s autobiographies. Lara Vapnek describes the historical inhibitions that shaped the self-presentation of pioneering American labor activist Elizabeth Gurley Flynn in the early twentieth century such that she omitted her sexual relationships with both women and men from her autobiographical writings. Overlapping with Vapnek’s historical (...) focus, Nora Doyle’s essay takes a new look at Gertrude Stein’s bestknown and most accessible work, The Autobiography of Alice B. Toklas, seeing it as Stein’s clever reworking of the women’s genre of domestic fiction in its pairing of a domesticated wife with a “genius” husband. In her examination of Kamala Das’s Balyakala Smaranakal (Memories of childhood), Sharmila Sreekumar discusses how the memoir’s depiction of self-deferral rather than self-realization unsettles autobiographical conventions through its troubling of the relationship between “self,” “life,” and “writing” that is constitutive of the genre. In Olga Zilberbourg’s short story, two women are baffled as they contemplate a friend’s suicide: what does it say about their own accomplishments and losses? Attention to the visual aspects of women’s lives and to their embodiment is highlighted in Estelle Carol’s memoir about her time spent as a member of the Graphic Collective of the Chicago Women’s Liberation Union in the 1970s. Corey Hickner-Johnson’s lyrical essay describes the first-person I of the poem as pushing herself to a physical extreme. Her autobiographical crisis-moment, depicted in acutely visceral and visual terms, wills into relief life’s underlying colors against a backdrop of otherwise drab monotony and disappointment. Feminist graphic artwork is discussed in Hillary Chute’s review essay on the newly popular genre of graphic novels by women. Alexandra Ketchum’s “‘The Place We’ve Always Wanted to Go But Never Could Find’: Finding Woman Space in Feminist Restaurants and Cafés in Ontario 1974–1982” and Samantha Pergadia’s “Geologies of 8 Sex and Gender: Excavating the Materialism of Gayle Rubin and Judith Butler” shift our attention away from individual life trajectories to broader sweeps of space and time. Ketchum’s history of feminist restaurants and cafes in Ontario, Canada, in the mid 1970s to early 1980s encourages us to consider the importance of space to the formation of feminist solidarities and political organizing, while Pergadia’s analysis of the geological understandings that undergird the work of both Gayle Rubin and Judith Butler invites us to rethink the temporalities through which gendered and sexed subjects, as well as academic disciplines, are formed. In closing, Ashwini Tambe reflects on the #MeToo movement and how we might fashion a more responsive public reckoning with sexual coercion. The issue leads off with Vapnek’s essay, “The Rebel Girl Revisited: Rereading Elizabeth Gurley Flynn’s Life Story.” As Vapnek details, Flynn, an activist in the Industrial Workers of the World, chronicled her life only as far as 1926. Although she envisioned women’s emancipation as an integral component of the socialist revolution, her self-censorship reveals “how communism as well as anticommunism has limited our knowledge of the feminist past.” Flynn remained committed to socialism and women’s rights and continued to agitate for social change, but her efforts to narrate her later life were stymied by internal inhibitions and external forces. For a decade she lived with another woman at a time when leftists were not open about same-sex relationships. Nor did she wish to reveal her sexual relationships with a number of men or the psychological breakdown she suffered in 1926. Joining the US Communist Party in 1936 re-energized her career as a labor organizer and resulted in her being sent to prison from 1955 to 1957 during the period of the Red Scare in the United States. By her middle age, she had experienced not only nonconventional personal relationships but also a dramatic change in her appearance: rather than the slim girl pictured on the cover of songs designed to encourage the labor movement, she was a stout, matronly woman. Inhibited from revising her autobiography to account for her later life... (shrink)

Weber-Fechner Law states that the perceived intensity is proportional to the logarithm of the stimulus. Recent experiments suggest that this law also holds true for perception of numerosity. Therefore, the use of a logarithmic scale for the quantification of the perceived intensity may also depend on how the cognitive apparatus processes information. If Weber-Fechner law is the result of natural selection, then the logarithmic scale should be better, in some sense, than other biologically feasible scales. We consider the minimization of (...) the relative error as the target of natural selection and we provide a formal proof that the logarithmic scale minimizes the maximal relative error. (shrink)

The fact that Oswald T. Avery (1877-1955) did not become a Nobel Laureate for his discovery of DNA as the genetic material has frequently been cited as a prime example of a mistake made in the awarding of the Nobel Prizes. The late Nobel Laureate Arne Tiselius explained the oversight away by saying that Avery "was an old man when he made his discovery" (Litell 1967)—although Avery was actually younger than several others who won the Nobel Prize around the same (...) time. Later, in somewhat of a contradiction, Tiselius said that Avery was the most deserving scientist not to have received the Nobel Prize for his work (Judson 2003).The opening of the Nobel archives 50 years after Avery's name was cited gives insights into ..

Traditional discussions about the arrow of time in general involve the concept of entropy. In the cosmological context, the direction past-to-future is usually related to the direction of the gradient of the entropy function of the universe. But the definition of the entropy of the universe is a very controversial matter. Moreover, thermodynamics is a phenomenological theory. Geometrical properties of space-time provide a more fundamental and less controversial way of defining an arrow of time for the universe as a whole. (...) We will call the arrow defined only on the basis of the geometrical properties of space-time, independently of any entropic considerations, “the global arrow of time.” In this paper we will argue that: (i) if certain conditions are satisfied, it is possible to define a global arrow of time for the universe as a whole, and (ii) the standard models of contemporary cosmology satisfy these conditions.

Causal selection is the cognitive process through which one or more elements in a complex causal structure are singled out as actual causes of a certain effect. In this paper, we report on an experiment in which we investigated the role of moral and temporal factors in causal selection. Our results are as follows. First, when presented with a temporal chain in which two human agents perform the same action one after the other, subjects tend to judge the later agent (...) to be the actual cause. Second, the impact of temporal location on causal selection is almost canceled out if the later agent did not violate a norm while the former did. We argue that this is due to the impact that judgments of norm violation have on causal selection—even if the violated norm has nothing to do with the obtaining effect. Third, moral judgments about the effect influence causal selection even in the case in which agents could not have foreseen the effect and did not intend to bring it about. We discuss our findings in connection to recent theories of the role of moral judgment in causal reasoning, on the one hand, and to probabilistic models of temporal location, on the other. (shrink)

This article is divided in three parts in order to investigate on the authorial and creative philosophical production in the Brazilian academic environment. In the first part, we show the challenge to authorial production in philosophy in Brazil, starting from the example of recent initiatives in the philosophy of religion. In the second part, by means of an analogy with music, we intend to argue that the plead for a greater promotion of authorial philosophy in Brazil does not mean to (...) devaluate the work with history of philosophy, which seems to be the predominant approach in academic philosophy in our country. The third part addresses the challenges to the formation of philosophical authorship, based on the triplet student-professor-knowledge, and acknowledging objective and subjective aspects of learning.

To counter the pandemic caused by severe acute respiratory syndrome coronavirus 2, some have proposed accelerating SARS-CoV-2 vaccine development through controlled human infection trials. These trials would involve the deliberate exposure of relatively few young, healthy volunteers to SARS-CoV-2. We defend this proposal against the charge that there is still too much uncertainty surrounding the risks of COVID-19 to responsibly run such a trial.

Mathematicians often conduct aesthetic judgements to evaluate mathematical objects such as equations or proofs. But is there a consensus about which mathematical objects are beautiful? We used a comparative judgement technique to measure aesthetic intuitions among British mathematicians, Chinese mathematicians, and British mathematics undergraduates, with the aim of assessing whether judgements of mathematical beauty are influenced by cultural differences or levels of expertise. We found aesthetic agreement both within and across these demographic groups. We conclude that judgements of mathematical beauty (...) are not strongly influenced by cultural difference, levels of expertise, and types of mathematical objects. Our findings contrast with recent studies that found mathematicians often disagree with each other about mathematical beauty. (shrink)

Recommender Systems (RecSys) have been around since the early days of the Internet, helping users navigate the vast ocean of information and the increasingly available options that have been available for us ever since. The range of tasks for which one could use a RecSys is expanding as the technical capabilities grow, with the disruption of Machine Learning representing a tipping point in this domain, as in many others. However, the increase of the technical capabilities of AI-powered RecSys did not (...) come with a thorough consideration of their ethical implications and, despite being a well-established technical domain, the potential impacts of RecSys on their users are still under-assessed. This paper aims at filling this gap in regards to one of the main impacts of RecSys: personal autonomy. We first describe how technology can affect human values and a suitable methodology to identify these effects and mitigate potential harms: Value Sensitive Design (VSD). We use VSD to carry out a conceptual investigation of personal autonomy in the context of a generic RecSys and draw on a nuanced account of procedural autonomy to focus on two components: competence and authenticity. We provide the results of our inquiry as a value hierarchy and apply it to the design of a speculative RecSys as an example. (shrink)

Stakeholder engagement and dialogue have a central role in defining the relations between organisations and their internal and external interlocutors. Drawing upon the analysis of dialogic motifs, power–conflict dynamics and sociopolitical perspectives, and based on a set of interviews with the stakeholders of a consumer-owned cooperative, the research explores the dialogic potential of stakeholder engagement. The analysis revealed a fragmented picture where the co-design and co-implementation aspects were mainly related to the non-business areas of cooperative life, while business logic dominated (...) the most central aspects. Stakeholder engagement was mainly related to consensus building, while dialogic engagement based on a pluralistic understanding was only partially considered and then neglected. The social capital in the local area, the growing size of the organisation and the related power structure embrace stakeholder engagement, influencing the orientation of the dialogic dynamic. The analysis indicates that a dialogic exchange is a relative concept which depends on the interests involved and the topics discussed. It also reveals that the key factors in the democratisation of stakeholder engagement are a mutual understanding and long-term opportunities. Common sociopolitical aspects are also important, but they do not necessarily guarantee the creation of dialogism paths. The research contributes to the critical dialogic literature in revealing whether and how stakeholder engagement has been implemented in a specific setting. It also shows the limitations of voluntarist stakeholder engagement initiatives. (shrink)

In this article I expound some of the main criticisms by David Hume and Immanuel Kant against the legitimacy of natural theology, the philosophical activity of presenting arguments for or against the existence of God. The aim is not to contribute to the scholarship in history of philosophy, but as a starting point for describing the main lines of Richard Swinburne’s approach to natural theology in terms of inductive probabilistic arguments. His proposal has been part of a current philosophical movement (...) of re-establishing the argumentative debate on the existence and nature of God, an area that has been growing in quantity and quality since the 1970’s.

This article intends to show that Plantinga’s criticism against Bayesianism as an account of what is involved in rationality does not apply to all forms of Bayesianism. Swinburne’s version, based on a logical theory of probability, is an example of Bayesianism not hit by Plantinga’s criticism. In addition, the article argues that the problem of dwindling probabilities – pointed out by Plantinga in Warranted Christian Belief (2000) – vanishes in a Bayesian approach. So, even if it is not a sufficient (...) account of rationality, Bayesianism helps to understand important elements of inductive reasoning, especially those relative to cumulative cases. (shrink)

ABSTRACT Through an interdisciplinary literature review, this propositional paper explores the emergence and unfolding of professionals’ moral identity conflicts involving important but contrasting values. Building on the exemplary case of physicians’ professional-religious dilemmas in End-of-Life circumstances, we develop a multilevel model of professional-personal identity conflict dynamics in ethically-charged situations in which we integrate individual-level mechanisms with organizational-level boundary conditions, namely peer social support and ethical climate, in relation to psychological well-being. Our conceptual model contributes to the ethics, identity and human (...) behavior literature by advancing suggestions of how professionals may prevent or/and resolve moral conflicts concerning also other identities and contexts.

O artigo pretende avaliar criticamente o conceito de fé e o modo como a fé cristã é racionalmente justificada por Alvin Plantinga em sua principal obra Warranted Christian Belief (2000). Para tanto, o texto parte de uma comparação com a proposta de Richard Swinburne. Após discutir brevemente a epistemologia geral de Plantinga, o texto expõe a sua aplicação à crença em Deus e à fé cristã. A tese de Plantinga de que a fé não constitui um “salto no escuro” e (...) que o seu componente não-teórico é semelhante ao amor erótico é comparada com a visão de Swinburne, segundo a qual a fé firme pode comportar elementos de incerteza na crença e supõe uma decisão voluntária, sendo, por isso mesmo, meritória. A comparação sugerirá que as diferenças indicam uma possibilidade de complementaridade entre as duas concepções. (shrink)

Este artigo visa refletir sobre a moral contemporânea a partir da ética de Nietzsche, tendo como foco principal a sua _Genealogia da Moral_ e, como contraponto a ser problematizado, o livro _The weariness of the self_ do sociólogo francês Alain Ehrenberg. De início, para analisar alguns tipos morais relevantes na primeira obra, revisamos o itinerário genealógico entre a “vontade de verdade” cristã e o niilismo budista (ou “ceticismo em matéria de moral”), destacando ainda alguns comentários de Nietzsche em torno de (...) Kant e o utilitarismo inglês. A autocrítica kantiana do conhecimento, afinal, manteve intacta a valoração negativa (cristã) da vida ao não questionar o valor em si da verdade. Por sua vez, ao arrogar o bem definitivo à felicidade, o utilitarismo inglês tornou a compaixão cristã compatível com o “ceticismo em matéria de moral”. A partir disso, argumentamos que a nova figura moralmente exemplar — não sendo mais a do cristão, alvo principal da genealogia nietzschiana — é a do budista, uma vez que este adere integralmente o niilismo. Em um segundo momento deste estudo, problematizamos a tese de Ehrenberg segundo a qual a figura do “indivíduo soberano” teria hoje se tornado hegemônica sob a égide da categoria da depressão. Não sendo concebível, sob o prisma nietzschiano, tal “indivíduo soberano” deprimido descrito por Ehrenberg, observamos, por fim, que é o niilismo que efetivamente se prolifera hoje: a partir da ilusão de superação total da moralidade, a moral contemporânea cultiva a fraqueza e o cansaço fisiológico através de um programa de combate irrestrito ao sofrimento.

Perception of time is susceptible to distortions; among other factors, it has been suggested that the perceived duration of a stimulus is affected by the observer’s expectations. It has been hypothesized that the duration of an oddball stimulus is overestimated because it is unexpected, whereas repeated stimuli have a shorter perceived duration because they are expected. However, recent findings suggest instead that fulfilled expectations about a stimulus elicit an increase in perceived duration, and that the oddball effect occurs because the (...) oddball is a target stimulus, not because it is unexpected. Therefore, it has been suggested that top-down attention is sometimes sufficient to explain this effect, and sometimes only necessary, with an additional contribution from saliency. However, how the expectedness of a target stimulus and its salient features affect its perceived duration is still an open question. In the present study, participants’ expectations about and the saliency of target stimuli were orthogonally manipulated with stimuli presented on a short (Experiment 1) or long (Experiment 2) temporal scale. Four repetitive standard stimuli preceded each target stimulus in a task in which participants judged whether the target was longer or shorter in duration than the standards. Engagement of top-down attention to target stimuli increased their perceived duration to the same extent irrespective of their expectedness. A small but significant additional contribution to this effect from the saliency of target stimuli was dependent on the temporal scale of stimulus presentation. In Experiment 1, saliency only significantly increased perceived duration in the case of expected target stimuli. In contrast, in Experiment 2, saliency exerted a significant effect on the overestimation elicited by unexpected target stimuli, but the contribution of this variable was eliminated in the case of expected target stimuli. These findings point to top-down attention as the primary cognitive mechanism underlying the perceptual extraction and processing of task-relevant information, which may be strongly correlated with perceived duration. Furthermore, the scalar properties of timing were observed, favoring the pacemaker-accumulator model of timing as the underlying timing mechanism. (shrink)

This study investigates the relationship between personality traits and coping styles among college students in private higher educational institution. Hence, employing correlational design to assess the relationship between coping styles and personality of 150 college students. The statistical analysis reveals that the r coefficient of 0.54 indicates a moderate positive correlation between the variables. The p-value of 0.00, which is less than 0.05, leads to the decision to reject the null hypothesis. Hence, a significant relationship exists between coping style and (...) personality traits among fourth-year college students in a private state university. (shrink)

In Mexico, significant ethical and social issues have been raised by the COVID-19 pandemic. Some of the most pressing issues are the extent of restrictive measures, the reciprocal duties to healthcare workers, the allocation of scarce resources, and the need for research. While policy and ethical frameworks are being developed to face these problems, the gender perspective has been largely overlooked in most of the issues at stake. Domestic violence is the most prevalent form of violence against women, which can (...) be exacerbated during a pandemic: stress and economic uncertainty are triggers for abuse, and confinement limits access to support networks. Confinement also exacerbates the unfair distribution of unpaid labor, which is disproportionately assigned to women and girls, and highlights inequality in the overall labor market. Lack of security measures has resulted in attacks towards health workers, particularly female nurses, due to fear of contamination. Finally, resource results in lack of access to other health necessities, including sexual and reproductive health services. Research across all disciplines to face—and to learn from—this crisis should be done through a gender lens, because understanding the realities of women is essential to understand the pandemic’s true effects in Mexico and the world.

For a theory T, we study relationships among IΔ n +1 (T), LΔ n+1 (T) and B * Δ n+1 (T). These theories are obtained restricting the schemes of induction, minimization and (a version of) collection to Δ n+1 (T) formulas. We obtain conditions on T (T is an extension of B * Δ n+1 (T) or Δ n+1 (T) is closed (in T) under bounded quantification) under which IΔ n+1 (T) and LΔ n+1 (T) are equivalent. These conditions depend (...) on Th Πn +2 (T), the Π n+2 –consequences of T. The first condition is connected with descriptions of Th Πn +2 (T) as IΣ n plus a class of nondecreasing total Π n –functions, and the second one is related with the equivalence between Δ n+1 (T)–formulas and bounded formulas (of a language extending the language of Arithmetic). This last property is closely tied to a general version of a well known theorem of R. Parikh. Using what we call Π n –envelopes we give uniform descriptions of the previous classes of nondecreasing total Π n –functions. Π n –envelopes are a generalization of envelopes (see [10]) and are closely related to indicators (see [12]). Finally, we study the hierarchy of theories IΔ n+1 (IΣ m ), m≥n, and prove a hierarchy theorem. (shrink)

The Chinese room argument has presented a persistent headache in the search for Artificial Intelligence. Since it first appeared in the literature, various interpretations have been made, attempting to understand the problems posed by this thought experiment. Throughout all this time, some researchers in the Artificial Intelligence community have seen Symbol Grounding as proposed by Harnad as a solution to the Chinese room argument. The main thesis in this paper is that although related, these two issues present different problems in (...) the framework presented by Harnad himself. The work presented here attempts to shed some light on the relationship between John Searle’s intentionality notion and Harnad’s Symbol Grounding Problem. (shrink)

Onora O’Neill hat 1984 den Zusammenhang zwischen grundsätzlichen Bedenken gegenüber dem ethischen Autonomiebegriff und der Kritik an der paternalistisch geprägten medizinethischen Praxis hergestellt, nicht die tatsächliche Einwilligung des konkreten Patienten zu berücksichtigen, sondern die angenommene, hypothetische Einwilligung, die ein idealisierter, völlig rationaler Patient geben würde.

Evolutionary applications of game theory present one of the most pedagogically accessible varieties of genuine, contemporary theoretical biology. We present here Oyun (OY-oon, http://charlespence.net/oyun), a program designed to run iterated prisoner’s dilemma tournaments, competitions between prisoner’s dilemma strategies developed by the students themselves. Using this software, students are able to readily design and tweak their own strategies, and to see how they fare both in round-robin tournaments and in “evolutionary” tournaments, where the scores in a given “generation” directly determine contribution (...) to the population in the next generation. Oyun is freely available, runs on Windows, Mac, and Linux computers, and the process of creating new prisoner’s dilemma strategies is both easy to teach and easy for students to grasp.

Gottfried Wilhelm Leibniz is the self-proclaimed inventor of the binary system and is considered as such by most historians of mathematics and/or mathematicians. Really though, we owe the groundwork of today’s computing not to Leibniz but to the Englishman Thomas Harriot and the Spaniard Juan Caramuel de Lobkowitz, whom Leibniz plagiarized. This plagiarism has been identified on the basis of several facts: Caramuel’s work on the binary system is earlier than Leibniz’s, Leibniz was acquainted—both directly and indirectly—with Caramuel’s work and (...)

ABSTRACT The aim of the present article is to rebuild picturebooks’ identity as polyphonic cultural objects based on a brief historical trajectory. Dialogue established between text and reader in contemporary picturebook’s production is broadened by the presence of different semiosis that allow multiple voices to be heard, since they act as meaning enhancers. The Bakhtinian concept of polyphony is herein held at the picturebook reflections scope to set contrast in children’s literature, which has a moralizing nature and is substantiated from (...) a monological perspective. The books by Angela Lago, who is a representative of the Brazilian children’s literature, are herein analyzed to disclose multimodal aspects found in this cultural object (book). In conclusion, picturebooks open a window of possibilities for open minded and creative readings, as well as for different readers, due to their polysemic and polyphonic nature. (shrink)

We evaluate whether evidence from conceptual combination supports the relational priming model of analogy. Representing relations implicitly as patterns of activation distributed across the semantic network provides a natural and parsimonious explanation of several key phenomena observed in conceptual combination. Although an additional mechanism for role resolution may be required, relational priming offers a promising approach to analogy.

El presente artículo tiene por intención principal dilucidar las distinciones y relaciones conceptuales que existen entre labor, trabajo y ocio, en el pensamiento de Hannah Arendt y Walter Benjamin, a modo de esclarecer cómo los posicionamientos de ambos autores contribuyen a la crítica de la concepción del trabajo moderno. Para ello, será necesario exponer los matices conceptuales de la obra de Arendt, a saber, la distinción entre trabajo y labor, con el fin de trazar las diferencias y puntos de encuentro (...) con las reflexiones de Benjamin en torno a los cambios traídos como consecuencia del auge del capitalismo industrial y en la experiencia del ocio. Entre estos matices, esclarecimientos y contrastes, es preciso no solo destacar la importancia de la relación e influencia de ambos autores, sino su vigencia en las problemáticas sociales contemporáneas al respecto.
