BackgroundAdolescents living with human immunodeficiency virus (HIV) experience challenges, including lack of involvement in their care as well nondisclosure of HIV status, which leads to poor adherence to antiretroviral therapy (ART). Parents have authority over their children, but during adolescence there is an increasing desire for independence. The aim of the study was to explore adolescents’ experience of challenges identified by adolescents ages 10–19 years attending HIV care and treatment at Temeke Regional Referral Hospital in Tanzania. MethodsAn exploratory descriptive qualitative (...) design was employed in the HIV Care and Treatment Centre (CTC) in the Out-Patient Department at the Temeke Regional Referral Hospital in Tanzania with adolescents living with HIV who were 10–19 years of age. A total of 22 adolescents participated in semi-structured face-to-face interviews after parental consent and adolescent assent were obtained. Participants were interviewed about their participation in decisions to be tested for HIV and enrolled in the CTC, concerns surrounding disclosure of their HIV status to the adolescent or to others, stigma and discrimination, and the effect of these challenges on their adherence to medication. All interviews were audio-taped, transcribed verbatim in Swahili, and back-translated to English. Data analysis included both inductive and deductive thematic analysis.ResultsQualitative themes identified included lack of participation in decisions about HIV testing, challenges to enrollment in care and treatment; issues around disclosure of HIV status, such as delays in disclosure to the adolescent and disclosure to other persons and benefits and harms of such disclosures; and factors supporting and interfering with adherence to ART, such as parental support, organizational (clinic) support and problems, and self-stigmatization and shame.ConclusionLack of adolescents’ involvement in their care decision making and delayed disclosure of HIV status to the adolescent were identified concerns, leading to poor adherence to ART among adolescents. Disclosure to others, especially teachers, helped adolescents at school to take their medication properly. Disclosure to others led to stigma and discrimination for some adolescents. More research is needed to better understand the role of disclosure and its benefits and challenges for HIV-positive adolescents in Tanzania. (shrink)

The ever-increasing application of algorithms to decision-making in a range of social contexts has prompted demands for algorithmic accountability. Accountable decision-makers must provide their decision-subjects with justifications for their automated system’s outputs, but what kinds of broader principles should we expect such justifications to appeal to? Drawing from political philosophy, I present an account of algorithmic accountability in terms of the democratic ideal of ‘public reason’. I argue that situating demands for algorithmic accountability within this justificatory framework enables us to (...) better articulate their purpose and assess the adequacy of efforts toward them.

Kim’s causal exclusion argument purports to demonstrate that the non-reductive physicalist must treat mental properties (and macro-level properties in general) as causally inert. A number of authors have attempted to resist Kim’s conclusion by utilizing the conceptual resources of Woodward’s interventionist conception of causation. The viability of these responses has been challenged by Gebharter, who argues that the causal exclusion argument is vindicated by the theory of causal Bayesian networks (CBNs). Since the interventionist conception of causation relies crucially on CBNs (...) for its foundations, Gebharter’s argument appears to cast significant doubt on interventionism’s anti-reductionist credentials. In the present article, we both (1) demonstrate that Gebharter’s CBN-theoretic formulation of the exclusion argument relies on some unmotivated and philosophically significant assumptions (especially regarding the relationship between CBNs and the metaphysics of causal relevance), and (2) use Bayesian networks to develop a general theory of causal inference for multi-level systems that can serve as the foundation for an anti-reductionist interventionist account of causation.1.

Platonism is the most pervasive philosophy of mathematics. Indeed, it can be argued that an inarticulate, half-conscious Platonism is nearly universal among mathematicians. The basic idea is that mathematical entities exist outside space and time, outside thought and matter, in an abstract realm. In the more eloquent words of Edward Everett, a distinguished nineteenth-century American scholar, "in pure mathematics we contemplate absolute truths which existed in the divine mind before the morning stars sang together, and which will continue to exist (...) there when the last of their radiant host shall have fallen from heaven." In What is Mathematics, Really?, renowned mathematician Rueben Hersh takes these eloquent words and this pervasive philosophy to task, in a subversive attack on traditional philosophies of mathematics, most notably, Platonism and formalism. Virtually all philosophers of mathematics treat it as isolated, timeless, ahistorical, inhuman. Hersh argues the contrary, that mathematics must be understood as a human activity, a social phenomenon, part of human culture, historically evolved, and intelligible only in a social context. Mathematical objects are created by humans, not arbitrarily, but from activity with existing mathematical objects, and from the needs of science and daily life. Hersh pulls the screen back to reveal mathematics as seen by professionals, debunking many mathematical myths, and demonstrating how the "humanist" idea of the nature of mathematics more closely resembles how mathematicians actually work. At the heart of the book is a fascinating historical account of the mainstream of philosophy--ranging from Pythagoras, Plato, Descartes, Spinoza, and Kant, to Bertrand Russell, David Hilbert, Rudolph Carnap, and Willard V.O. Quine--followed by the mavericks who saw mathematics as a human artifact, including Aristotle, Locke, Hume, Mill, Peirce, Dewey, and Lakatos. In his epilogue, Hersh reveals that this is no mere armchair debate, of little consequence to the outside world. He contends that Platonism and elitism fit well together, that Platonism in fact is used to justify the claim that "some people just can't learn math." The humanist philosophy, on the other hand, links mathematics with geople, with society, and with history. It fits with liberal anti-elitism and its historical striving for universal literacy, universal higher education, and universal access to knowledge and culture. Thus Hersh's argument has educational and political ramifications. Written by the co-author of The Mathematical Experience, which won the American Book Award in 1983, this volume reflects an insider's view of mathematical life, based on twenty years of doing research on advanced mathematical problems, thirty-five years of teaching graduates and undergraduates, and many long hours of listening, talking to, and reading philosophers. A clearly written and highly iconoclastic book, it is sure to be hotly debated by anyone with a passionate interest in mathematics or the philosophy of science. (shrink)

Decisions based on algorithmic, machine learning models can be unfair, reproducing biases in historical data used to train them. While computational techniques are emerging to address aspects of these concerns through communities such as discrimination-aware data mining and fairness, accountability and transparency machine learning, their practical implementation faces real-world challenges. For legal, institutional or commercial reasons, organisations might not hold the data on sensitive attributes such as gender, ethnicity, sexuality or disability needed to diagnose and mitigate emergent indirect discrimination-by-proxy, such (...) as redlining. Such organisations might also lack the knowledge and capacity to identify and manage fairness issues that are emergent properties of complex sociotechnical systems. This paper presents and discusses three potential approaches to deal with such knowledge and information deficits in the context of fairer machine learning. Trusted third parties could selectively store data necessary for performing discrimination discovery and incorporating fairness constraints into model-building in a privacy-preserving manner. Collaborative online platforms would allow diverse organisations to record, share and access contextual and experiential knowledge to promote fairness in machine learning systems. Finally, unsupervised learning and pedagogically interpretable algorithms might allow fairness hypotheses to be built for further selective testing and exploration. Real-world fairness challenges in machine learning are not abstract, constrained optimisation problems, but are institutionally and contextually grounded. Computational fairness tools are useful, but must be researched and developed in and with the messy contexts that will shape their deployment, rather than just for imagined situations. Not doing so risks real, near-term algorithmic harm. (shrink)

In this paper, I use interventionist causal models to identify some novel Newcomb problems, and subsequently use these problems to refine existing interventionist treatments of causal decision theory. The new Newcomb problems that make trouble for existing interventionist treatments involve so-called ‘exotic choice’—that is, decision-making contexts where the agent has evidence about the outcome of her choice. I argue that when choice is exotic, the interventionist can adequately capture causal decision-theoretic reasoning by introducing a new interventionist approach to updating on (...) exotic evidence. But I also argue that this new updating procedure is principled only if the interventionist trades in the typical interventionist conception of choice for an alternative Ramseyan conception. I end by arguing that the guide to exotic choice developed here may, despite its name, be useful in some everyday contexts. (shrink)

McGee argues that it is sometimes reasonable to accept both x and x-> without accepting y->z, and that modus ponens is therefore invalid for natural language indicative conditionals. Here, we examine McGee's counterexamples from a Bayesian perspective. We argue that the counterexamples are genuine insofar as the joint acceptance of x and x-> at time t does not generally imply constraints on the acceptability of y->z at t, but we use the distance-based approach to Bayesian learning to show that applications (...) of modus ponens are nevertheless guaranteed to be successful in an important sense. Roughly, if an agent becomes convinced of the premises of a modus ponens argument, then she should likewise become convinced of the argument's conclusion. Thus we take McGee's counterexamples to disentangle and reveal two distinct ways in which arguments can convince. Any general theory of argumentation must take stock of both. (shrink)

It is explained that, in the sense of the sociologist Erving Goffman, mathematics has a front and a back. Four pervasive myths about mathematics are stated. Acceptance of these myths is related to whether one is located in the front or the back.

Jim Joyce has argued that David Lewis’s formulation of causal decision theory is inadequate because it fails to apply to the “small world” decisions that people face in real life. Meanwhile, several authors have argued that causal decision theory should be developed such that it integrates the interventionist approach to causal modeling because of the expressive power afforded by the language of causal models, but, as of now, there has been little work towards this end. In this paper, I propose (...) a variant of Lewis’s causal decision theory that is intended to meet both of these demands. Specifically, I argue that Lewis’s causal decision theory can be rendered applicable to small world decisions if one analyzes his dependency hypotheses as causal hypotheses that depend on the interventionist causal modeling framework for their semantics. I then argue that this interventionist variant of Lewis’s causal decision theory is preferable to interventionist causal decision theories that purportedly generalize Lewis’s through the use of conditional probabilities. This is because Lewisian interventionist decision theory captures the causal decision theorist’s conviction that any correlation between what the agent does and cannot cause should be irrelevant to the agent’s choice, while purported generalizations do not.

There are two distinct meanings to ‘mathematical proof’. The connection between them is an unsolved problem. The first step in attacking it is noticing that it is an unsolved problem.

This article examines the role of culture in the metaphorical/metonymic conceptualizations of fear, a primary emotion, in two languages—Akan (a West African, Kwa language) and English. The article adopts the general framework of conceptual metaphor theory (CMT) to compare and contrast the differences and/or similarities in the conceptualizations as well as the language-specific construals or elaborations of shared conceptual metaphors of fear in the two languages. The analysis of the language-specific realizations of the shared metaphorical/metonymic conceptualizations of the emotion concept (...) reveals both similarities and differences in the two languages, showing support for the cultural embodied cognition thesis, namely, the similarities in the conceptualization of emotions across cultures may be explained in terms of universal embodied cognition from which general metaphorical principles derive. However, the differences in language-specific elaborations may be explained in terms of cultural filtering of the general universal conceptualizations to reflect human experiences that are more salient to a particular sociocultural group. This analysis also shows a metaphor–metonymy interaction in the conceptualization of emotions across cultures. (shrink)

Meek and Glymour use the graphical approach to causal modeling to argue that one and the same norm of rational choice can be used to deliver both causal-decision-theoretic verdicts and evidential-decision-theoretic verdicts. Specifically, they argue that if an agent maximizes conditional expected utility, then the agent will follow the causal decision theorist’s advice when she represents herself as intervening, and will follow the evidential decision theorist’s advice when she represents herself as not intervening. Since Meek and Glymour take no stand (...) on whether agents should represent themselves as intervening, they provide more general advice than standard causal decision theorists and evidential decision theorists. But I argue here that even Meek and Glymour’s advice is not sufficiently general. This is because their advice is not sensitive to the distinct ways in which agents can fail to intervene, and there are decision-making contexts in which agents can reasonably have non-extreme confidence that they are intervening. I then show that the most natural extension of Meek and Glymour’s framework fails, but offer a generalization of my “Interventionist Decision Theory” that does not suffer from the same problems.

Although excess blood collection has characterized U.S. national disasters, most dramatically in the case of September 11, periodic shortages of blood have recurred for decades. In response, I propose a new model of medical philanthropy, one that specifically uses charitable contributions to health care as blood donation incentives. I explain how the surge in blood donations following 9/11 was both transient and disaster-specific, failing to foster a greater continuing commitment to donate blood. This underscores the importance of considering blood donation (...) incentives. I defend charitable incentives as an alternative to financial incentives, which I contend would further extend neoliberal market values into health care. I explain my model's potential appeal to private foundations or public–private partnerships as a means for expanding both the pool of blood donors and the prosocial benefit of each act of blood donation. Finally I link my analysis to the empirical literature on blood donation incentives. (shrink)

Brentano is often considered the originator of the fitting-attitudes analysis of value, on which to be valuable is to be that which it’s fitting to value. But there has been comparatively little attention paid to Brentano’s argument for this analysis. That argument advances the stronger claim that fittingness is part of the analysis of normativity. Since the argument rests on an analogy between truth and fittingness, its impact may seem limited by the idiosyncratic features of Brentano’s later notion of truth. (...) I argue, however, that the Brentanian argument is defensible even if fittingness is analogized to a more typical realist account of truth. The result is what I call the worldly Brentanian account of normativity. I defend this account as a form of naturalistic realism. I then show how the account can fare better than prominent alternatives against two kinds of error-theoretic arguments. (shrink)

The problem of the reality and nature of novelty in the universe has long engaged the attention of philosophers. “There is nothing new under the sun” is one ancient weighty utterance. On the other hand, “you cannot step twice into the same river”, said Heraclitus, for in the interval between your first and second steps, the river has changed and you have changed. One recent attempt to analyze this problem and other affiliated problems, is the theory of emergence.

Background Caring is a core function of nurses and it confers upon them ethical obligations as ethical agents. Failure to carry out such ethical obligations raises ethical concerns. This study was not intended to explore ethical concerns, but the reported findings reveal problems which have ethical implications. This paper aims to elucidate the ethical issues inherent in the findings and propose strategies to mitigate them. Research design and methods An exploratory-descriptive qualitative design was used within a larger Action Research Study. (...) Data were collected through focus group discussions with nurse/midwives, and through exit interviews which were conducted with the women who participated in the study on their day of discharge. Six focus group discussions and thirty exit interviews were conducted, and data were analysed through thematic analysis. Participants and research context The study took place at selected maternal and child healthcare settings in Lilongwe, Malawi. The participants were nurse/midwives and women who were admitted in maternal and child healthcare settings and were purposively sampled. Ethical considerations Ethical approval was obtained from the relevant ethics committee and all ethical guidelines were followed in the conduct of the study. Findings The findings are presented under three themes which emerged from the data. The findings reveal effects of staff shortages on patient outcomes, problems experienced in low resource clinical settings and disrespectful nurse/patient communication. Conclusion The findings reveal that institutional factors constrain moral agency and patient safety is severely compromised in some of the clinical settings in Malawi which raises serious ethical concerns.

Though common sense says that causes must temporally precede their effects, the hugely influential interventionist account of causation makes no reference to temporal precedence. Does common sense lead us astray? In this paper, I evaluate the power of the commonsense assumption from within the interventionist approach to causal modeling. I first argue that if causes temporally precede their effects, then one need not consider the outcomes of interventions in order to infer causal relevance, and that one can instead use temporal (...) and probabilistic information to infer exactly when X is causally relevant to Y in each of the senses captured by Woodward’s interventionist treatment. Then, I consider the upshot of these findings for causal decision theory, and argue that the commonsense assumption is especially powerful when an agent seeks to determine whether so-called “dominance reasoning” is applicable.

Bayesians standardly claim that there is rational pressure for agents’ credences to cohere across time because they face bad (epistemic or practical) consequences if they fail to diachronically cohere. But as David Christensen has pointed out, groups of individual agents also face bad consequences if they fail to interpersonally cohere, and there is no general rational pressure for one agent's credences to cohere with another’s. So it seems that standard Bayesian arguments may prove too much. Here, we agree with Christensen (...) that there is no general rational pressure to diachronically cohere, but we argue that there are particular cases in which there is rational pressure to diachronically cohere, as well as particular cases in which interpersonal probabilistic coherence is rationally required. More generally, we suggest that Bayesian arguments for coherence apply whenever a collection (of agents or time slices) has a shared dimension of value and an ability to coordinate their actions in a range of cases relevant to that value. Typically, this shared value and ability to coordinate is very strong across the time slices of one human being, and very weak across different human beings, but there are special cases where these can switch—i.e., some groups of humans will have as much reason for their beliefs to cohere across a particular range of cases as the time slices of one human usually do, but some time slices of a human will have as much freedom to differ in their beliefs from the others as the members of a group usually do.

This article reports findings of a hermeneutic phenomenological study that explored the clinical learning experience for Malawian undergraduate student nurses. The study revealed issues that touch on both nursing education and practice, but the article mainly reports the practice issues. The findings reveal the emotions that healthcare workers in Malawi encounter as a consequence of practising in resource-poor settings. Furthermore, there is severe nursing shortage in most clinical settings in Malawi, and this adversely affects the performance of nurses because of (...) the excess workload it imposes on them. The results of the study also illustrate loss of professional pride among some of the nurses, and the article argues that such a demeanour is a consequence of burnout. However, despite these problems, the study also reveals that there are some nurses who have maintained their passion to care. (shrink)

ArgumentDuring the second quarter of the nineteenth century, an argument raged about the identity of a small freshwater fish: was the parr a distinct species, or merely the young of the salmon? This “Parr Controversy” concerned both fishermen and ichthyologists. A central protagonist in the controversy was a man of ambiguous social and scientific status: a gamekeeper from Scotland named John Shaw. This paper examines Shaw’s heterogeneous practices and the reception of his claims by naturalists as he struggled to find (...) a footing on the “gradient of attributed competence” (Rudwick 1985). The case demonstrates the context-specific nature of expert-lay boundaries and identities and explores a range of material and linguistic resources available for negotiating them. Arguing for a view of Shaw’s trajectory as simultaneously one of being a “practical man” and of becoming a naturalist, the paper explores both the permeability of social hierarchies in knowledge production and their effective role in the regulation of competency.

The issues of tithes and seed sowing have taken a central focus in contemporary Christianity in Nigeria among the preachers. Many a time, it is assumed that tithes and seed sowing are requirements for salvation, prosperity and total well-being of the members. Making many to believe that Christianity is a money-venture business one can succeed if he knows how to hoodwink the gullible. Many have been deceived that by parting with a substantial amount of money in the name of sowing (...) seed, their problems would be solved. Unfortunately, the person’s problem may remain the same or even be compounded. This paper evaluates the activities, attitude and their inordinate ambitions. It examines the impact of tithe and seed sowing on Christianity in Nigeria. The research method adopted for this work is the qualitative phenomenological method. The paper observed that the value of tithe and seed sowing has changed from what is prescribed in the bible to what is preached on the pulpits. The study recommends among other things, that these preachers should preach the gospel with decorum and as it were in the bible so that its influence on Nigerians will bring about a reduction in crime, corruption and other immoral activities in Nigeria. Contribution: The article is focused on the issues of tithes and seed sowing. It underscores the fact that the message of tithe and seed sowing has become a means of siphoning members and enriching the preachers. It further reveals its negative and positive impacts such as, the promotion of corruption and fraud in the church and society, contribution to the decline of morality in the church and the society, increasing crime rate and increasing poverty rate in Nigeria among others.

This work seeks to honor Michael Novak’s contribution to sport ethics by returning to his seminal work, The Joy of Sports. Novak runs an alternate route in developing his ethic, drawing largely on the school of political realism, particularly the work of Reinhold Niebuhr. In so doing, he offers a distinctive lens through which to approach to the myriad ethical issues in sport, including those related to competition, violence, and engagement in foul play. The essay outlines four core dimensions of (...) realism within Novak’s larger corpus in order to elucidate their unfolding within The Joy of Sports. It also contributes to an understanding of how political realism might be appropriated for sport ethics. (shrink)

How the insane asylum became a laboratory of democracy is revealed in this provocative look at the treatment of the mentally ill in nineteenth-century France. Political thinkers reasoned that if government was to rest in the hands of individuals, then measures should be taken to understand the deepest reaches of the self, including the state of madness. Marcel Gauchet and Gladys Swain maintain that the asylum originally embodied the revolutionary hope of curing all the insane by saving the glimmer (...) of sanity left in them. Their analysis of why this utopian vision failed ultimately constitutes both a powerful argument for liberalism and a direct challenge to Michel Foucault's indictment of liberal institutions. The creation of an artificial environment was meant to encourage the mentally ill to live as social beings, in conditions that resembled as much as possible those prevailing in real life. The asylum was therefore the first instance of a modern utopian community in which a scientifically designed environment was supposed to achieve complete control over the minds of a whole category of human beings. Gauchet and Swain argue that the social domination of the inner self, far from being the hidden truth of emancipation, represented the failure of its overly optimistic beginnings. Madness and Democracy combines rich details of nineteenth-century asylum life with reflections on the crucial role of subjectivity and difference within modernism. Its final achievement is to show that the lessons learned from the failure of the asylum led to the rise of psychoanalysis, an endeavor focused on individual care and on the cooperation between psychiatrist and patient. By linking the rise of liberalism to a chapter in the history of psychiatry, Gauchet and Swain offer a fascinating reassessment of political modernity. (shrink)
