Background There is a growing concern about artificial intelligence (AI) applications in healthcare that can disadvantage already under-represented and marginalised groups (eg, based on gender or race). Objectives Our objectives are to canvas the range of strategies stakeholders endorse in attempting to mitigate algorithmic bias, and to consider the ethical question of responsibility for algorithmic bias. Methodology The study involves in-depth, semistructured interviews with healthcare workers, screening programme managers, consumer health representatives, regulators, data scientists and developers. Results Findings reveal considerable (...) divergent views on three key issues. First, views on whether bias is a problem in healthcare AI varied, with most participants agreeing bias is a problem (which we call the bias-critical view), a small number believing the opposite (the bias-denial view), and some arguing that the benefits of AI outweigh any harms or wrongs arising from the bias problem (the bias-apologist view). Second, there was a disagreement on the strategies to mitigate bias, and who is responsible for such strategies. Finally, there were divergent views on whether to include or exclude sociocultural identifiers (eg, race, ethnicity or gender-diverse identities) in the development of AI as a way to mitigate bias. Conclusion/significance Based on the views of participants, we set out responses that stakeholders might pursue, including greater interdisciplinary collaboration, tailored stakeholder engagement activities, empirical studies to understand algorithmic bias and strategies to modify dominant approaches in AI development such as the use of participatory methods, and increased diversity and inclusion in research teams and research participant recruitment and selection.

Non-striving is an important aspect of mindfulness practice, but it has not been sufficiently researched. This study examine whether a strange loop based task — Infinite Water Scooping Task — performed for ten minutes, has an effect on non-striving behaviour and performance in a subsequent word length comparison task. Results showed that performance (number of correct trials) did not differ significantly between the two groups, though the experimental group tended to perform worse. However, participants in the experimental group took a (...) significantly shorter time to respond to the word length comparison task than those in the control group. It is inferred that shorter time taken reflects response without investing much effort to count with care, i.e. non-striving. The present study demonstrates that the brief strange loop task implemented in this study elicited non-striving behaviour compared to the effects of the control task and adds to the understanding of non-striving in the context of mindfulness. The Infinite Water Scooping Task may be useful for illustrating and teaching non-striving within mindfulness practice. (shrink)

I develop an interdisciplinary framework for understanding the nature of agents and agency that is compatible with recent developments in the metaphysics of science and that also does justice to the mechanistic and normative characteristics of agents and agency as they are understood in moral philosophy, social psychology, neuroscience, robotics, and economics. The framework I develop is internal perspectivalist. That is to say, it counts agents as real in a perspective-dependent way, but not in a way that depends on an (...) external perspective. Whether or not something counts as an agent depends on whether it is able to have a certain kind of perspective. My approach differs from many others by treating possession of a perspective as more basic than the possession of agency, representational content/vehicles, cognition, intentions, goals, concepts, or mental or psychological states; these latter capabilities require the former, not the other way around. I explain what it means for a system to be able to have a perspective at all, beginning with simple cases in biology, and show how self-contained normative perspectives about proper function and control can emerge from mechanisms with relatively simple dynamics. I then describe how increasingly complex control architectures can become organized that allow for more complex perspectives that approach agency. Next, I provide my own account of the kind of perspective that is necessary for agency itself, the goal being to provide a reference against which other accounts can be compared. Finally, I introduce a crucial distinction that is necessary for understanding human agency: that between inclinational and committal agency, and venture a hypothesis about how the normative perspective underlying committal agency might be mechanistically realized.

This research investigates 3- and 5-year-olds' relative fairness in distributing small collections of even or odd numbers of more or less desirable candies, either with an adult experimenter or between two dolls. The authors compare more than 200 children from around the world, growing up in seven highly contrasted cultural and economic contexts, from rich and poor urban areas, to small-scale traditional and rural communities. Across cultures, young children tend to optimize their own gain, not showing many signs of (...) self-sacrifice or generosity. Already by 3 years of age, self-optimizing in distributive justice is based on perspective taking and rudiments of mind reading. By 5 years, overall, children tend to show more fairness in sharing. What varies across cultures is the magnitude of young children's self-interest. More fairness (less self-interest) in distributive justice is evident by children growing up in small-scale urban and traditional societies thought to promote more collective values. (shrink)

There are currently between twenty and thirty civil wars worldwide, while at a global level the Cold War has been succeeded by a "war on drugs" and a "war on terror" that continues to rage a decade after 9/11. Why is this, when we know how destructive war is in both human and economic terms? Why do the efforts of aid organizations and international diplomats founder so often? In this important book David Keen investigates why conflicts are so prevalent and (...) so intractable, even when one side has much greater military resources. Could it be that endemic disorder and a "state of emergency" are more useful than bringing conflict to a close? Keen asks who benefits from wars--whether economically, politically, or psychologically—and argues that in order to bring them successfully to an end we need to understand the complex vested interests on all sides.

In this contribution we will present a generalization of de Finetti's betting game in which a gambler is allowed to buy and sell unknown events' betting odds from more than one bookmaker. In such a framework, the sole coherence of the books the gambler can play with is not sucient, as in the original de Finetti's frame, to bar the gambler from a sure-win opportunity. The notion of joint coherence which we will introduce in this paper characterizes those coherent (...) books on which sure- win is impossible. Our main results provide geometric characterizations of the space of all books which are jointly coherent with a xed one. As a consequence we will also show that joint coherence is decidable.

Winning isn't everything. It's the only thing. Vince Lombardi The most important thing in the Olympic Games is not to win but to take part, just as the most important thing in life is not the triumph but the struggle. The essential thing is not to have conquered, but to have fought well. The Olympic Creed These two statements reflect two very different approaches to sport. The Lombardi quote reflects the view that we should take a win-at-all-costs approach. By contrast, (...) the Olympic Creed includes the idea that there is something more important in sport than victory. Perhaps the Olympic Creed is correct, and Lombardi mistaken. Perhaps the value of winning is found primarily in its potential to foster both athletic and moral excellence, while the overvaluing of victory for its own sake suffers from several deficiencies as an approach to sport.

Inexpressibility results in Finite Model Theory are often proved by showing that Duplicator, one of the two players of an Ehrenfeucht game, has a winning strategy on certain structures.In this article a new method is introduced that allows, under certain conditions, the extension of a winning strategy of Duplicator on some small parts of two finite structures to a global winning strategy.As applications of this technique it is shown that • — Graph Connectivity is not expressible in existential monadic second-order (...) logic , even in the presence of a built-in linear order,• — Graph Connectivity is not expressible in MonNP even in the presence of arbitrary built-in relations of degree n0, and• — the presence of a built-in linear order gives MonNP more expressive power than the presence of a built-in successor relation.

Women are currently under-represented in academic philosophy. This paper first considers ways in which the competitive atmosphere of philosophy might help explain this lack of diversity. For example, women are stereotyped as less competitive and as less capable of exhibiting what are considered ‘winning behaviours’ in philosophy, leading to a more stressful, less rewarding experience; lower assessments of merit by themselves and others; and potential under-performance. Second, this paper draws out the implications of this discussion for high school philosophy competitions. (...) Are these competitions likely to further exacerbate existing trends of representation, by associating philosophy with competition and winning? I argue that the way that these philosophy competitions are set up, as friendly, low-stakes team events, rewarding attributes that are ‘stereotypically female’, mean that these events are likely to support, rather than damage, diversity in the discipline. Indeed, there are reasons to think that these events form an important part of an image-change that is required for philosophy if it is to become a more diverse discipline at university-level and beyond. I finish by offering a series of practical recommendations for high school philosophy competitions, in light of the aim of increasing diversity in academic philosophy, but also with the more immediate aim of making these competitions inclusive, enjoyable events for everyone.

Like many secular institutions in the West, the military often has overlooked the role religion plays in political life and conflict. The United States and its military increasingly are enmeshed in religiously charged struggles associated with the global ?war on terror? that require a more complex understanding of religion than traditional military education and training affords. A different approach, therefore, is needed given the high stakes and perils of not comprehending how religion is part of the problem in the (...) wars waged by today's servicemen and women. Recently, some military voices have offered proposals to redress the deficit in religious knowledge and understanding. This article echoes those calls and goes further to argue that efforts to increase ?religious situational awareness,? though essential, depend upon a deeper educational foundation and broad-based study of religion. Several illustrations, offered from a U.S. perspective, show how the study of religion enhances knowledge about military life, culture, and outlook as they bear upon contemporary global conflict.

Although many studies have demonstrated an influence of uniform colors on sports performance, there are still more questions than answers regarding this issue. In our study, participants from Poland and China watched a two-minute video of a semi-professional boxing match. The participants viewed six different versions of the same fight - the original was modified to change the colors of the boxers’ trunks. We experimentally confirmed that “black wins” and “red wins” effects exist, but in a way that caused (...) an erroneous perception of the number of blows landed by boxers wearing red and black trunks fighting against boxers in blue trunks. We also showed that both effects are similarly strong even in Chinese culture, where the color red has different connotations from those in Western cultures. Additionally, our results suggest that context might play a very important role in the assessments of the boxers - color only influenced the perception of the weaker boxer. Finally, our findings suggest that the topic of the influence of colors on sports competitions has not been thoroughly investigated and further studies are necessary. (shrink)

Brazil stands out at the global level for having implemented several policies intending to promote agroecology as a productive paradigm for small-holder farmers. However, the impacts of this process of institutionalization of agroecology still lack research and debates that evaluate the effectiveness of these policies. In this paper, we assess and discuss the impacts of a policy specifically focused on education in agroecology, the support to the establishment of Centers for the Study of Agroecology and Organic Production (NEAs) in more (...) than 150 higher education institutions throughout Brazil. NEAs bring together teachers, researchers, and students who engage in teaching, research, and extension activities in partnerships with peasant farmers, their organizations, and rural extension workers. The hypothesis that guides our analysis is that this support to establish NEAs allowed redistribution of symbolic power in the universities where they were established, supporting agroecology to gain greater legitimacy inside and outside the university field. Based on an in-depth study of four NEAs, performed through participant observation and documentary analysis, the NEAs are evaluated from the perspective of social fields in dispute, first in a university sphere, but also from the perspective of training people in integrative and transdisciplinary thinking that will contest the industrial-corporate food regime. Our findings suggest that the State support to university groups dedicated to the promotion of agroecology has allowed the construction of what we have named agroecological spaces, which symbolically dispute the dominant paradigms in educational institutions, supporting the constitution of material and immaterial agroecological territories.

We introduce two new iteration games: the game , which is a strengthening of the weak iteration game, and the game , which is somewhat stronger than but weaker than the full iteration game of length ω1.

Traditionally the doping debate has been dominated by those who want to see doping forbidden (the prohibitionist view) and those who want to see it permitted (the ban abolitionist view). In this article, the authors analyse a third position starting from the assertion that doping use is a symptom of the paradigm of highly competitive elite sports, in the same way as addictions reflect current social paradigms in wider society. Based upon a conceptual distinction between occasional use, habitual use and (...) addiction, and focusing on the physical and/or mental dependency caused by the addictive use of a certain drug, we argue that marihuana, stimulants and anabolic steroid abuse—the most frequently detected substances in doping tests—satisfies at least one, often both, of these conditions. A conclusion to be drawn from the authors' arguments is that the prohibitionist view is inappropriate for dealing with doping, as the severe sanctions attached to it will cut the doper off her/his social and professional environment, thereby risking reinforcing her/his addictive conduct. But the ban abolitionist view seems inappropriate as well. At first sight, it seems neither rational nor humane not to intervene when confronted with conduct which is highly harmful for the individual and upon which she has reduced or no control whatsoever. Instead the authors' proposal will be to contextualise dopers' conduct within sport healthcare and see it strictly in relation to each athlete's personal background. Developing preventive programmes—implemented through person-tailored counselling and eventually treatment, rather than severe sanctions or the mere lifting of the ban—seems to be a more reasonable, and probably more efficient, way of conducting ‘the war against doping’.

I argue that in purely professional games of pure chance, such as slot machines, roulette, baccarat or pachinko, any instance of cheating that successfully deceives the judge can be ‘part of the game’. I examine, and reject, various proposals for the ‘ethos’ that determines how we ought to interpret the formal rules of games of pure chance, such as being a test of skill, a matter of entertainment, a display of aesthetic beauty, an opportunity for hedonistic pleasure, and a fraternal (...) activity. Ultimately, I argue that ‘winning the benefit’ is the only ethos that can apply in purely professional games of pure chance, and that if we interpret the formal rules according to this ethos, cheating that is undertaken with respect for the judge’s authority, but that attempts to cause the judge of the game to ‘voluntarily’ relinquish the benefit of the game by deceiving them into thinking that the formal rules of the game have been followed, is impermissible but acceptable cheating, and is therefore within, rather than outside, the game. Here, I define ‘games of pure chance’ as games in which chance is the only determinant of winning. (shrink)

Community engagement is increasingly promoted as a marker of good, ethical practice in the context of international collaborative research in low-income countries. There is, however, no widely agreed definition of community engagement or of approaches adopted. Justifications given for its use also vary. Community engagement is, for example, variously seen to be of value in: the development of more effective and appropriate consent processes; improved understanding of the aims and forms of research; higher recruitment rates; the identification of important ethical (...) issues; the building of better relationships between the community and researchers; the obtaining of community permission to approach potential research participants; and, the provision of better health care. Despite these diverse and potentially competing claims made for the importance of community engagement, there is very little published evidence on effective models of engagement or their evaluation.

This thesis explores the merits and limits of John Hawthorne’s contextualist analysis of free will. First, I argue that contextualism does better at capturing the ordinary understanding of ‘free will’ than competing views because it best accounts for the way in which our willingness to attribute free will ordinarily varies with context. Then I consider whether this is enough to conclude that the contextualist has won the free will debate. I argue that this would be hasty, because the contextualist, (...) unlike her competitors, cannot tell us whether any particular agent is definitively free, and therefore cannot inform any practices that are premised on whether a particular agent is morally responsible. As such, I argue that whether the contextualist “wins the free will debate” depends on whether it is more important to capture the ordinary understanding of ‘free will’ or more important to inform our practices of ascribing moral responsibility.

Unlike other females, but like many males, they are assertive, they take chances, and they are not chaste.

Part of the draw of athletics is its straightforwardness. There are nuances to competitions to make them more sporting contests, but at the end of a long jump competition whomever records the longest jump should win. Unfortunately, a recent rule-change at the highest level of the sport – the “Final 3” format – undermined this simplicity for the horizontal jumps and the throws for some of the 2020 and much of the 2021 seasons. While fortunately this rule was largely reverted (...) within days of the initial submission of this paper, it’s still valuable to critically evaluate why such a rule is problematic so as to better understand of the value of sporting competitions and give guidance on future rule changes, be they in athletics or other sports. To that end, we will be drawing from the literature on the purpose and value of competitions and coupling that with simulations based on data from actual top-tier long jump competitions to show that the Final 3 format makes for significantly worse competitions than the standard format.

Heroism is apparently nonadaptive in Darwinian terms, so why does it exist at all? Risk-taking and heroic behavior are predominantly male tendencies, and literature and legend reflect this. This study explores the possibility that heroism persists in many human cultures owing to a female preference for risk-prone rather than risk-averse males as sexual partners, and it suggests that such a preference may be exploited as a male mating strategy. It also attempts to quantify the relative influences of altruism and (...) bravery in the evolution of heroism. Our study found that females do prefer risk-prone brave males to risk-averse non-brave males, and that men are aware of this preference. Bravery in a male was shown to be the stronger factor influencing female choice of short-term partners, long-term partners, and male friends, with altruism playing a lesser part in their choice. Altruism was deemed important in long-term relationships and friendships, but for short-term liaisons, non-altruists were preferred to altruists. Heroism may therefore have evolved owing to a female preference for brave, risk-prone males because risk-taking acts as an honest cue for "good genes." Altruism was judged to be a less influential factor in the evolution of heroism than bravery and a demonstrated willingness to take risks. (shrink)

Rhetoric is the power of persuasion, or influence, through words. And in many ways, comics exemplify, through their heroes and heroines, the power of rhetoric, of the written and spoken word to convince, persuade, and ultimately move people.

Wonder Woman remains relevant in the twenty‐first century, holding her own against her (...) male counterparts, and arguably embodying a passionate plea of persuasion. More than any other character, beyond brute force, beyond the use of technology and battle tactics where might makes right, even if right is just, Wonder Woman often mobilizes argumentation as her greatest weapon.

Nurses are responsible for the well-being and quality of life of many people, and therefore must meet high standards of technical and ethical competence. The most common form of ethical guidance is a code of ethics/professional practice; however, little research on how codes are viewed or used in practice has been undertaken. This study, carried out in six European countries, explored nurses’ opinions of the content and function of codes and their use in nursing practice. A total of 49 focus (...) groups involving 311 nurses were held. Purposive sampling ensured a mix of participants from a range of specialisms. Qualitative analysis enabled emerging themes to be identified on both national and comparative bases. Most participants had a poor understanding of their codes. They were unfamiliar with the content and believed they have little practical value because of extensive barriers to their effective use. In many countries nursing codes appear to be ‘paper tigers’ with little or no impact; changes are needed in the way they are developed and written, introduced in nurse education, and reinforced/implemented in clinical practice.

In this paper, I argue that what counts as the proper function of a trait is a matter of the de facto perspective that the biological system, itself, possesses on what counts as proper functioning for that trait. Unlike non-perspectival accounts, internal perspectivalism does not succumb to generality problems. But unlike external perspectivalism, internal perspectivalism can provide a fully naturalistic, mind-independent grounding of proper function and natural norms. The attribution of perspectives to biological systems is intended to be neither metaphorical (...) nor anthropomorphic: I do not mean to imply that such systems thereby must possess agency, cognition, intentions, concepts, or mental or psychological states. Instead, such systems provide the grounding for norms of performance when they internally enforce their own standard of (i.e., their own perspective on) what constitutes proper functioning or malfunctioning. By operating with a fixed, determinate level of generality, such systems provide the basis for an account of proper function that is immune to generality problems. (shrink)

Hannah Arendt's early biography of Rahel Varnhagen, an eighteenth-century German-Jew, provides a revolutionary feminist component to her political theory. In it, Arendt grapples with the theoretical constitution of a female subject and relates Jewish alterity, identity, and history to feminist politics. Because she understood the "female condition" of difference as belonging to the political subject rather than an autonomous self, her theory entails a "politics of alterity" with applications for feminist practice.

The casinos want you to lose money. In fact, the minute you step into their facility, they are betting on it. So what does it take to walk into a casino and walk out a winner? On 21: The Philosophy of Blackjack gives you the tools to sit down at a blackjack table and beat the casino at their own game. Author and blackjack expert Andrew Marx outlines the critical steps it takes to be a winner. A blackjack player combines (...) knowledge of the game, proven strategy, timing and practice to put him at the top of his game. The book includes step by step instructions on how to play blackjack and teaches tried and true strategies to decrease the house advantage. But more than just know-how and strategy, On 21: The Philosophy of Blackjack also asks what is the right attitude for winning? The author discusses how to pick the right table, how to pick the right dealer, which variations on the house rules are the best advantage to the player. He talks how the mental discipline it takes to play the game well, and what to do when the cards aren't running in your favor. With helpful lessons spread throughout the book, full color visual aids and a detailed chapter index, On 21: The Philosophy of Blackjack not only gives you a solid understanding of the game, but talks meaningfully about the mental attitude you need to think like a winner. Perfect for beginners and intermediate players, the book also lays out the steps to take to move towards professional gambling. Written by a veteran blackjack player who lived in Las Vegas for over ten years and has traveled to many casinos in other cities, all of the information included here is laid out in easy-to-understand language with supporting visual images.

With the emergence of numerous link prediction methods, how to accurately evaluate them and select the appropriate one has become a key problem that cannot be ignored. Since AUC was first used for link prediction evaluation in 2008, it is arguably the most preferred metric because it well balances the role of wins and the role of draws. However, in many cases, AUC does not show enough discrimination when evaluating link prediction methods, especially those based on local similarity. Hence, we (...) propose a new metric, called W-index, which considers only the effect of wins rather than draws. Our extensive experiments on various networks show that the W-index makes the accuracy scores of link prediction methods more distinguishable, and it can not only widen the local gap of these methods but also enlarge their global distance. We further show the reliability of the W-index by ranking change analysis and correlation analysis. In particular, some community-based approaches, which have been deemed effective, do not show any advantages after our reevaluation. Our results suggest that the W-index is a promising metric for link prediction evaluation, capable of offering convincing discrimination. (shrink)

The central place accorded the notion of ‘sustainable development' among those attempting to overcome ecological problems could be one of the main reasons for their failure. ‘Ecological civilization' is proposed and defended as an alternative. ‘Ecological civilization' has behind it a significant proportion of the leadership of China who would be empowered if this notion were taken up in the West. It carries with it the potential to fundamentally rethink the basic goals of life and to provide an alternative image (...) of the future.

A number of philosophers have defended the view that seemingly intellectually arrogant behaviours are epistemically beneficial. In this chapter I take issue with most of their conclusions. I argue, for example, that we should not expect steadfastness in one's belief in the face of contrary evidence nor overconfidence in one’s own abilities to promote better evaluation of the available evidence resulting in good-quality group-judgement. These features of individual thinkers are, on the contrary, likely to lead groups to end up in (...) stalemates and to polarise over issues. It is true that groups benefit from including members that, prior to discussion, hold diverse views. But disagreement benefits group judgement only when it is transient, rather than entrenched. That is, groups reach better quality conclusions when a number of diverse opinions are disseminated and evaluated fairly before reaching a consensus. If this is right, it would seem that individual qualities, such as open-mindedness and even-handedness about the epistemic value of opinions other than one's own, rather than steadfastness or overconfidence are conducive to better quality group judgement.

Existing accounts of mechanistic causation are not suited for understanding causation in biological and neural mechanisms because they do not have the resources to capture the unique causal structure of control heterarchies. In this paper, we provide a new account on which the causal powers of mechanisms are grounded by time-dependent, variable constraints. Constraints can also serve as a key bridge concept between the mechanistic approach to explanation and underappreciated work in theoretical biology that sheds light on how biological systems (...) channel energy to actively respond to the environment in adaptive ways, perform work, and fulfill the requirements to maintain themselves far from equilibrium. We show how the framework applies to several concrete examples of control in simple organisms as well as the nervous system of complex organisms. (shrink)

It has been suggested that community advisory boards can play a role in minimising exploitation in international research. To get a better idea of what this requires and whether it might be achievable, the paper first describes core elements that we suggest must be in place for a CAB to reduce the potential for exploitation. The paper then examines a CAB established by the Shoklo Malaria Research Unit under conditions common in resource-poor settings – namely, where individuals join with a (...) very limited understanding of disease and medical research and where an existing organisational structure is not relied upon to serve as the CAB. Using the Tak Province Border Community Ethics Advisory Board as a case study, we assess the extent to which it might be able to take on a role minimising exploitation were it to decide to do so. We investigate whether, after two years in operation, T-CAB is capable of assessing clinical trials for exploitative features and addressing those found to have them. The findings show that, although T-CAB members have gained knowledge and developed capacities that are foundational for one-day taking on a role to reduce exploitation, their ability to critically evaluate studies for the presence of exploitative elements has not yet been strongly demonstrated. In light of this example, we argue that CABs may not be able to perform such a role for a number of years after initial formation, making it an unsuitable responsibility for many short-term CABs.

A reexamination of the Nobel-prize-winning experiment in which the antiproton was discovered reveals that the associated antimesons might be traveling faster than light.

I argue, for example, that we should not expect steadfastness in one's belief in the face of contrary evidence nor overconfidence in one’s own abilities to promote better evaluation of the available evidence resulting in good-quality group-judgement. These features of individual thinkers are, on the contrary, likely to lead groups to end up in (...) stalemates and to polarise over issues. It is true that groups benefit from including members that, prior to discussion, hold diverse views. But disagreement benefits group judgement only when it is transient, rather than entrenched. That is, groups reach better quality conclusions when a number of diverse opinions are disseminated and evaluated fairly before reaching a consensus. If this is right, it would seem that individual qualities, such as open-mindedness and even-handedness about the epistemic value of opinions other than one's own, rather than steadfastness or overconfidence are conducive to better quality group judgement.
