This paper revisits one of the first models of analog computation, the General Purpose Analog Computer . In particular, we restrict our attention to the improved model presented in [11] and we show that it can be further refined. With this we prove the following: the previous model can be simplified; it admits extensions having close connections with the class of smooth continuous time dynamical systems. As a consequence, we conclude that some of these extensions (...) achieve Turing universality. Finally, it is shown that if we introduce a new notion of computability for the GPAC, based on ideas from computable analysis, then one can compute transcendentally transcendental functions such as the Gamma function or Riemann's Zeta function.

Church's thesis, that all reasonable definitions of “computability” are equivalent, is not usually thought of in terms of computability by acontinuouscomputer, of which the general-purpose analog computer (GPAC) is a prototype. Here we prove, under a hypothesis of determinism, that the analytic outputs of aC∞GPAC are computable by a digital computer.In [POE, Theorems 5, 6, 7, and 8], Pour-El obtained some related results. (The proof there of Theorem 7 depends on her Theorem 2, for which (...) the proof in [POE] is incorrect, but for which a correct proof is given in [LIR]. Also, the proof in [POE] of Theorem 8 depends on the unproved assertion that a solution of an algebraic differential equation must be analytic on an open subset of its domain. However, this assertion was later proved in [BRR].) As in [POE], we reduce the problem to a problem about solutions of certain systems of algebraic differential equations (ADE's). If such a system is nonsingular (i.e. if the “separant” does not vanish along the given solution), then the argument is very easy (see [VSD] for an even simpler situation), so that the essential difficulties arise fromsingularsystems. Our main tools in handling these difficulties are drawn from the excellent (and difficult) paper [DEL] by Denef and Lipshitz. The author especially wants to thank Leonard Lipshitz for his kind help in the preparation of the present paper.We emphasize here that our proof of the simulation result applies only to the GPAC as described below. The GPAC's form a natural subclass of the class of all analog computers, and are based on certain idealized components (“black boxes”), mostly associated with the technology of past decades. One can easily envisage other kinds of black boxes of an input-output character that would lead to different kinds of analog computers. (For example, one could incorporate delays, or spatial integrators in addition to the present temporal integrators, etc.) Whether digital simulation is possible for these “extended” analog computers poses a rich and challenging set of research questions.

In lieu of an abstract, here is a brief excerpt of the content:Inheriting Identity and Practicing TransformationThe Time of Feminist PoliticsShannon HoffA human life unfolds over time. No moment of it can be considered apart from the others, independently of the fact that the human being was and will be, and so no moment is sufficient on its own to tell us of the nature of that identity. Each moment is insufficient as an expression of who we are, as an (...) answer to the question of what we want to be, or as a point at which a full account of our identity could be given. And we live each moment as if afflicted by a dual blindness with regard to the past and future that lend it significance; while exercising pervasive influence in the present, this past and future are relatively inaccessible to our reflective insight. We are always “growing up,” so to speak, from out of a childhood that can never be the purely transparent object of reflection, to an adulthood or “accomplishment” of identity that is always in the mysterious future, unimaginable in the terms of the adolescence in which we find ourselves.My purpose here is to show how this issue resonates in the context of feminist philosophy, feminist critique, and feminist practice—that is, how a consideration of time and its impact on human experience allows us to highlight the accomplishments of various avenues of feminist thought, to elaborate their shortcomings in relation to each other, to perceive the reasons behind the tensions among them, and to understand the way in which they are (and should [End Page 167] be understood as) connected. I will work through the issue of what it means to live in the temporal dimensions of past, present, and future—what it means to inherit an already meaningful world, to be an individual in the present, and to be propelled into an uncertain future—so as to provide a general framework by which to interpret the history of feminist thought. I will explain these different temporal dimensions in terms of the (respective) ideas of cultivation, universality, and transformation, identifying the positive and negative significance of each and also the demand that the tensions among them be negotiated. Finally, I will show that feminist justice is in fact found here, as answerability to all three—to communities of cultivation, to the demands of universality, and to the inconclusiveness and transformability of human identity. While much feminist thinking has been committed to exploring these elements singly, in abstraction from the others, and while such work is important, it is also valuable to explicitly explore the relationships and tensions among these different aspects, to articulate how to act and think in light of this underlying conceptual context, and to do so in a more explicit and self-conscious way.There is, of course, a disadvantage to not exploring these elements on their own terms: namely, that one handles their subtleties roughly. A further and related danger is that involved in trying to draw a broad picture of a tradition with complex and conflicting elements, one that does not count itself as a tradition at times—as a “we,” a feminism, or a feminist thought.1 While I will talk about “feminism” or “feminist thought,” I do not presume that these differences do not exist; my goal is simply to explore what is involved in an elaboration of a critical interpretation of society, when the society one critically interprets is an agent in one’s formation. The description of the dynamics of human becoming, agency, and critique I develop below has the purpose of showing that it is possible to understand differences between feminist positions as complementary, a process that will lead me to underemphasize stringent divisions and charged oppositions and to focus on drawing connections. Let us turn now to a preliminary description of the conceptual framework I seek to construct.Feminism and TimeTo advance feminist purposes is, one might presume, to hope for and work toward a new and transformed reality in the future. It would seem, however, that this reality cannot be clearly envisioned in the present, since that would require the transformation of the very people envisioning it. In... (shrink)

RationaleSurrogates of critically ill patients often have inaccurate expectations about prognosis. Yet there is little research on how intensive care unit clinicians should discuss prognosis, and existing expert opinion-based recommendations give only general guidance that has not been validated with surrogate decision makers.ObjectiveTo determine the perspectives of key stakeholders regarding how prognostic information should be conveyed in critical illness.MethodsThis was a multicenter study at three academic medical centers in California, Pennsylvania, and Washington. One hundred eighteen key stakeholders completed in-depth (...) semistructured interviews. Participants included 47 surrogates of adult patients with acute respiratory distress syndrome; 45 clinicians working in study ICUs, including physicians, nurses, social workers, and spiritual care providers; and 26 experts in health communication, decision science, ethics, family-centered care, geriatrics, healthcare disparities, palliative care, psychology, psychiatry, and critical care.Measurements and main resultsThere was broad support among surrogates for existing expert recommendations, including truthful prognostic disclosure, emotional support, tailoring the disclosure strategy to each family's needs, and checking for understanding. In addition, stakeholders offered suggestions that add specificity to existing recommendations, including: In addition to conveying prognostic estimates, clinicians should help families "see the prognosis for themselves" by showing families radiographic images and explaining the clinical significance of physical manifestations of severe disease at the bedside. Many physicians did not support using numeric estimates to convey prognosis to families, whereas many surrogates, clinicians from other disciplines, and experts believed numbers could be helpful. Clinicians should conceptualize prognostic communication as an iterative process that begins with a preliminary mention of the possibility of death early in the ICU stay and becomes more detailed as the clinical situation develops. Although prognostic information should be initially disclosed by physicians, other members of the multidisciplinary team-nurses, social workers, and spiritual care providers-should be given explicit role responsibilities to reinforce physicians' prognostications and help families process a poor prognosis emotionally.ConclusionsFamily members, clinicians, and experts identified specific communication behaviors that clinicians should use to discuss prognosis in the critical care setting. These findings extend existing opinion-based recommendations and should guide interventions to improve communication about prognosis in ICUs. (shrink)

Aim:The purpose of this study was to explore how adolescent patients displaying developmental trauma experience and describe meaning in life. Schnell’s model of meaning in life is applied to explore meaningfulness, crises of meaning and sources of meaning. Method: The study has a qualitative design based on individual interviews with eight adolescents aged 14–18 years in treatment in an outpatient clinic for mental health care for children and adolescents. The interviews were transcribed and analyzed using systematic text condensation. Results: (...) The adolescents related meaning in life to the experience of coherence, intrinsic values, progress and belonging, or the absence of these. Examples of sources of meaning among the informants were positive relations with meaningful others, structure and routines, moments of well-being, achieving goals related to education, work and family, and seeking something else outside oneself such as playing computer games, being engaged in politics, being with animals, having a belief in a god or being outdoors in natural surroundings. Conclusion: Although the topic of meaning in life was unknown to this group, they used sources of meaning intuitively. This group seems to have similar preferences to the general population. More knowledge is needed on how the topic of meaning in life can be useful in therapy for adolescents with development trauma. (shrink)

From the early ninth century until about eight centuries later, the Middle East witnessed a series of both simple and systematic astronomical observations for the purpose of testing contemporary astronomical tables and deriving the fundamental solar, lunar, and planetary parameters. Of them, the extensive observations of lunar eclipses available before 1000 AD for testing the ephemeredes computed from the astronomical tables are in a relatively sharp contrast to the twelve lunar observations that are pertained to the four extant accounts (...) of the measurements of the basic parameters of Ptolemaic lunar model. The last of them are Taqī al-Dīn Muḥammad b. Ma‘rūf’s trio of lunar eclipses observed from Istanbul, Cairo, and Thessalonica in 1576–1577 and documented in chapter 2 of book 5 of his famous work, Sidrat muntaha al-afkar fī malakūt al-falak al-dawwār. In this article, we provide a detailed analysis of the accuracy of his solar and lunar observations. (shrink)

Paul Churchland's book (hereafter ER)is an entertaining and instructive advertisement for a "neurocomputational" vision of how the brain (and mind) works. While we agree with its general thrust, and commend its lucid pedagogy on a host of difficult topics, we note that such pedagogy often exploits artificially heightened contrast, and sometimes the result is a misleading caricature instead of a helpful simplification. In particular, Churchland is eager to contrast the explanation of consciousness that can be accomplished by his "aspiring (...) new structural and dynamic cognitive prototype: recurrent PDP networks" (p.266) with what strikes him as the retrograde introduction by Dennett of a virtual von Neumannesque machine--a "failed prototype"--as the key element in an explanation of human consciousness (in Consciousness Explained, 1991, hereafter, CE). We will try to show that by oversimplifying Dennett's alternative, he has taken a potential supplement to his own view--a much needed supplement--and transformed it in his imagination into a subversive threat. In part 1, we will expose and correct the mistaken contrasts. In part 2, we will compare the performance of the two views on Churchland's list of seven features of consciousness any theory must account for, showing that Dennett's account provides more than Churchland has recognized, and indeed offers answers to key questions that Churchland's account is powerless to address. At that point, Churchland's project and Dennett's could be seen to collaborate in a useful division of labor instead of being in mortal combat, were it not for what appears to be a fairly major disagreement about consciousness in non-human animals. Part 3 briefly examines this issue. It may be due to a misunderstanding, which when cleared up might restore the happy prospect of unification. (shrink)

Biological evolution is a complex blend of ever changing structural stability, variability and emergence of new phe- notypes, niches, ecosystems. We wish to argue that the evo- lution of life marks the end of a physics world view of law entailed dynamics. Our considerations depend upon dis- cussing the variability of the very ”contexts of life”: the in- teractions between organisms, biological niches and ecosys- tems. These are ever changing, intrinsically indeterminate and even unprestatable: we do not know ahead of (...) time the ”niches” which constitute the boundary conditions on selec- tion. More generally, by the mathematical unprestatability of the ”phase space”, no laws of mo- tion can be formulated for evolution. We call this radical emergence, from life to life. The purpose of this paper is the integration of variation and diversity in a sound concep- tual frame and situate unpredictability at a novel theoretical level, that of the very phase space. Our argument will be carried on in close comparisons with physics and the mathematical constructions of phase spaces in that discipline. The role of symmetries as invariant preserving transformations will allow us to under- stand the nature of physical phase spaces and to stress the differences required for a sound biological theoretizing. In this frame, we discuss the novel notion of ”enablement”. Life lives in a web of enablement and radical emergence. This will restrict causal analyses to differential cases. Mutations or other causal differ- ences will allow us to stress that ”non conservation princi- ples” are at the core of evolution, in contrast to physical dynamics, largely based on conservation principles as sym- metries. Critical transitions, the main locus of symmetry changes in physics, will be discussed, and lead to ”extended criticality” as a conceptual frame for a better understanding of the living state of matter.

A case study is presented of the development of computer-based support tools for power engineers in the electricity supply industry. The objective was to develop an expert system to support witching schedule production. A user-centred approach was followed which led the user community to conclude that a switching schedule production assistant (SSPA) was required which would leave control with the power engineer. Prototype systems were developed and evaluated in user trials which revealed that a significant and more general (...) purpose tool would be a computer generated electricity network display that the engineers could manipulate. The paper concludes that the process of enabling users to evaluate alternative forms of technology can facilitate the development systems that are useful, acceptable and usable. (shrink)

The INBIOSA project brings together a group of experts across many disciplines who believe that science requires a revolutionary transformative step in order to address many of the vexing challenges presented by the world. It is INBIOSA’s purpose to enable the focused collaboration of an interdisciplinary community of original thinkers. This paper sets out the case for support for this effort. The focus of the transformative research program proposal is biology-centric. We admit that biology to date has been more (...) fact-oriented and less theoretical than physics. However, the key leverageable idea is that careful extension of the science of living systems can be more effectively applied to some of our most vexing modern problems than the prevailing scheme, derived from abstractions in physics. While these have some universal application and demonstrate computational advantages, they are not theoretically mandated for the living. A new set of mathematical abstractions derived from biology can now be similarly extended. This is made possible by leveraging new formal tools to understand abstraction and enable computability. [The latter has a much expanded meaning in our context from the one known and used in computer science and biology today, that is "by rote algorithmic means", since it is not known if a living system is computable in this sense (Mossio et al., 2009).] Two major challenges constitute the effort. The first challenge is to design an original general system of abstractions within the biological domain. The initial issue is descriptive leading to the explanatory. There has not yet been a serious formal examination of the abstractions of the biological domain. What is used today is an amalgam; much is inherited from physics (via the bridging abstractions of chemistry) and there are many new abstractions from advances in mathematics (incentivized by the need for more capable computational analyses). Interspersed are abstractions, concepts and underlying assumptions “native” to biology and distinct from the mechanical language of physics and computation as we know them. A pressing agenda should be to single out the most concrete and at the same time the most fundamental process-units in biology and to recruit them into the descriptive domain. Therefore, the first challenge is to build a coherent formal system of abstractions and operations that is truly native to living systems. Nothing will be thrown away, but many common methods will be philosophically recast, just as in physics relativity subsumed and reinterpreted Newtonian mechanics. -/- This step is required because we need a comprehensible, formal system to apply in many domains. Emphasis should be placed on the distinction between multi-perspective analysis and synthesis and on what could be the basic terms or tools needed. The second challenge is relatively simple: the actual application of this set of biology-centric ways and means to cross-disciplinary problems. In its early stages, this will seem to be a “new science”. This White Paper sets out the case of continuing support of Information and Communication Technology (ICT) for transformative research in biology and information processing centered on paradigm changes in the epistemological, ontological, mathematical and computational bases of the science of living systems. Today, curiously, living systems cannot be said to be anything more than dissipative structures organized internally by genetic information. There is not anything substantially different from abiotic systems other than the empirical nature of their robustness. We believe that there are other new and unique properties and patterns comprehensible at this bio-logical level. The report lays out a fundamental set of approaches to articulate these properties and patterns, and is composed as follows. -/- Sections 1 through 4 (preamble, introduction, motivation and major biomathematical problems) are incipient. Section 5 describes the issues affecting Integral Biomathics and Section 6 -- the aspects of the Grand Challenge we face with this project. Section 7 contemplates the effort to formalize a General Theory of Living Systems (GTLS) from what we have today. The goal is to have a formal system, equivalent to that which exists in the physics community. Here we define how to perceive the role of time in biology. Section 8 describes the initial efforts to apply this general theory of living systems in many domains, with special emphasis on crossdisciplinary problems and multiple domains spanning both “hard” and “soft” sciences. The expected result is a coherent collection of integrated mathematical techniques. Section 9 discusses the first two test cases, project proposals, of our approach. They are designed to demonstrate the ability of our approach to address “wicked problems” which span across physics, chemistry, biology, societies and societal dynamics. The solutions require integrated measurable results at multiple levels known as “grand challenges” to existing methods. Finally, Section 10 adheres to an appeal for action, advocating the necessity for further long-term support of the INBIOSA program. -/- The report is concluded with preliminary non-exclusive list of challenging research themes to address, as well as required administrative actions. The efforts described in the ten sections of this White Paper will proceed concurrently. Collectively, they describe a program that can be managed and measured as it progresses. (shrink)

While training design choices seem amoral, they interact to determine training (in)effectiveness, potentially harming/benefiting trainees and organizations. These moral implications intensify when training is administered at scale (e.g., e-training) and focuses on social issues like sexual harassment (hereafter, SH). In fact, research on SH training shows it can elicit trainees’ gender-based biases against content messengers. We suggest that one such bias, resulting from messenger gender-occupation incongruence and influencing training effectiveness, is lowered perceptions of the messenger’s integrity. We also investigate whether (...) rich media will increase or decrease this perceived integrity penalty. Using an excerpt from real SH e-training and a sample [_N_ = _210_] consistent with the targeted training audience, we conducted a 2 × 2 × 2 relative comparison experiment (messenger gender x messenger occupation x media richness) and tested a moderated mediation model of the interactive effects of messenger gender-occupation incongruence and media richness on trainees’ perceptions of messenger integrity and training outcomes. Results suggest that trainees’ perceptions of messenger integrity decrease when the messenger’s gender is incongruent with their occupation, leading to worse outcomes in text-based training. These effects, however, are mitigated by increased media richness, providing support for media richness theory. Implications for researchers and practitioners are discussed. (shrink)

Background: Concerns have been expressed regarding the adequacy of ethics review systems in developing countries. Limited data are available regarding the structural and functional status of Research Ethics Committees (RECs) in the Middle East. The purpose of this study was to survey the existing RECs in Egypt to better understand their functioning status, perceived resource needs, and challenges. Methods: We distributed a self-administered survey tool to Egyptian RECs to collect information on the following domains: general characteristics of the (...) REC, membership composition, ethics training, workload, process of ethics review, perceived challenges to effective functioning, and financial and material resources. We used basic descriptive statistics to evaluate the quantitative data. Results: We obtained responses from 67% (12/18) of the identified RECs. Most RECs (10/12) have standard operating procedures and many (7/12) have established policies to manage conflicts of interests. The average membership was 10.3 with a range from 7-19. The predominant member type was physicians (69.5% of all of the REC members) with little lay representation (13.7%). Most RECs met at least once/month and the average number of protocols reviewed per meeting was 3.8 with a range from 1-10. Almost three-quarters of the members from all of the 12 RECs indicated they received some formal training in ethics. Regarding resources, roughly half of the RECs have dedicated capital equipment (e.g., meeting room, computers, office furniture, etc); none of the RECs have a formal operating budget. Perceived challenges included the absence of national research ethics guidelines and national standards for RECs and lack of ongoing training of its members in research ethics. Conclusion: Our study documents several areas of strengths and areas for improvements in the operations of Egyptian RECs. Regarding strengths, many of the existing RECs meet frequently, have a majority of members with prior training in research ethics, and have written policies. Regarding areas for improvements, many RECs should strive for a more diverse membership and should receive more financial resources and administrative support personnel. We recommend that RECs include more individuals from the community and develop a continuing educational program for its members. Institutional officials should be aware of the resource capacity needs of their RECs. (shrink)

I offer an explication of the notion of computer, grounded in the practices of computability theorists and computer scientists. I begin by explaining what distinguishes computers from calculators. Then, I offer a systematic taxonomy of kinds of computer, including hard-wired versus programmable, general-purpose versus special-purpose, analog versus digital, and serial versus parallel, giving explicit criteria for each kind. My account is mechanistic: which class a system belongs in, and which functions are computable by (...) which system, depends on the system's mechanistic properties. Finally, I briefly illustrate how my account sheds light on some issues in the history and philosophy of computing as well as the philosophy of mind. (shrink)

The problem of global climate changes has raised fundamental questions of justice in world politics centered around the vast discrepancies between the causes and the effects of global warming and the uneven levels of consumption/enjoyment of fossil fuels. The overwhelming majority of approaches in environmental ethics have focused on either distributive justice or rights-based frameworks. Climate change justice, however, can be explored through an alternative framework, an approach based on the recognition theory of Axel Honneth that has not been systematically (...) engaged with in this field. A critique of John Rawls’ The Law of Peoples as an exemplar of distributive approaches reveals a number of limitations inherent in Rawlsian models of climate-change justice. Honneth’s theory of recognition is an advance on distributive models toward a notion of climate justice in which the conditions necessary for the “functioning and flourishment” of human freedom includes climatic stability as a basic social condition. The ideal of mutual recognition provides a basis for environmental protections, including but not limited to the global atmosphere as a necessary condition for the realization of self-autonomy for all human kind.

In the section called “Observation of Nature” in the Phenomenology of Spirit, Hegel considers and criticizes a particular form of methodology which seeks final purposes by analogy. Through this methodology what is essential for thought is the recognition and demarcation of differentiae, which are imputed to natural objects as qualities by which things maintain their distinct and separate character - what Hegel calls their “being-for-self.” By these differentiae, then, the objects are categorized into types, or “natural kinds,” which, in turn, (...) are interpreted by natural philosophers according to a projected teleological system. Hegel’s critique is not aimed primarily at the categorization of objects, but at the method of interpretation used to characterize these categories as purposeful. In particular, Hegel is not criticizing the use of analogy as discussed in the biological writings of Aristotle, but the use of analogy by the transcendental idealists, especially Kant, who employs this method in the Critique of Judgment.

This paper develops a phenomenological defense of Ian Hacking's experimental realism about unobservable entities in physical science, employing historically undervalued resources from the phenomenological tradition in order to clarify the warrant for our ontological commitments in science. Building upon the work of Husserl, Merleau-Ponty and Heelan, the paper provides a phenomenological correction of the positivistic conception of perceptual evidence maintained by antirealists such as van Fraassen, the experimental relevance of which is illustrated through a phenomenological interpretation of the 1974 discovery (...) of the J/ ψ particle generally regarded as evidence for the charmed quark. The argument then turns to address known problems in Hacking's account, demonstrating that his own instrumentalist criterion of the real is inadequately rooted in the phenomenology of perception, and as a result, passes over the true ontological significance of experimental phenomena. The paper maintains that the proper criterion, only indirectly related to instrumentality, is the distinctive style of the real encountered in perception: empirical pregnancy. With this notion and Merleau-Ponty's associated reversibility thesis, I show that the phenomenological tradition provides insights into the warrant for our realist commitments that have yet to be adequately acknowledged by philosophers of science.

This thesis examines the key moral principles that should govern decision-making by police and military when using lethal force. To this end, it provides an ethical analysis of the following question: Under what circumstances, if any, is it morally justified for the agents of state-sanctioned security institutions to use lethal force, in particular the police and the military? Recent literature in this area suggests that modern conflicts involve new and unique features that render conventional ways of thinking about the ethics (...) of armed conflict, and the use of lethal force, as inadequate or redundant. In particular, there is an increased concern with the moral difficulties created by “non-standard” cases. This is where the police or military are obliged to operate outside their conventional contexts. In such non-standard cases, on what moral basis can (or should) state actors – especially the police and military – use lethal force? One approach argues that there is nothing morally exceptional about the use of lethal force by police or military. This says the only available moral justification for using lethal force is killing in self-defence or defence of others. In contrast, I use an institutional approach to develop a moral framework for the state’s morally exceptional use of lethal force. The institutional approach is concerned with the ends (telos) or purpose of a social institution. It says that the moral purpose of a social institution alters the moral responsibilities of its agents; what is referred to as role morality. My analysis demonstrates that there is an important moral distinction between justified killing in self-defence and state-sanctioned uses of lethal force. My claim is that police and military uses of lethal force are not morally justified in the same way as the average person’s use of lethal force (i.e. self-defence or defence of others). Instead, I argue that the state-sanctioned institutional role of police and military give these state actors special moral duties, and therefore exceptional moral justification, for using lethal force. I argue that the institutional end of the police is the preservation of public safety. This includes using lethal force where it is necessary to protect life and prevent serious injury to jurisdictional inhabitants. In contrast, a morally responsible state uses military force to defend the “common good.” That is, when it is necessary to defend the peaceful functioning of a state from armed threats or other forms of political violence. I then conclude that non-standard cases require the addition of jus ad vim (or the just use of military force short-of-war) as a hybrid element to the moral framework for the state-sanctioned use of lethal force. This provides a better way of applying ethics to the use of military force when defending the common good against serious threats in non-standard cases. This is because jus ad vim complements the conventional military paradigm by permitting the use of military capabilities to defend the common good. But, at the same time, it inhibits the move towards the more destructive levels of violence characteristic of conventional warfighting. (shrink)

In this chapter I provide resources for assessing the charge that post-secondary students are self-censoring. The argument is advanced in three broad steps. First, I argue that both a duality at the heart of the concept of self-censorship and the term’s negative lay connotation should incline us to limit the charge of self-censorship to a specific subset of its typical extension. I argue that in general we ought to use the neutral term “refrainment from speech,” reserving the more normatively (...) charged “self-censorship” for cases of bad refrainment. In the second step of the argument, I seek to narrow down what counts as bad refrainment by mapping broad categories of possible reasons for and consequences of refrainment from speech. I argue that in general refrainment from speech is only bad if it is for bad (or what I will later term vicious) reasons or has pernicious consequences. When considering pernicious consequences, I argue that we should be concerned in particular about systems that perpetuate the coercive silencing of marginalized voices. I draw on Kristie Dotson’s work to describe two means by which marginalized voices are systemically silenced: testimonial quieting and testimonial smothering. After considering these types of silencing, I circle back to the post-secondary context to assess whether there is cause for concern if, as some reports suggests, US college students are refraining from speech within the educational context.

How many sexes are there? What is the relationship between sex and gender? Is gender a product of nature, or nurture, or both? _In Beyond the Binary_, Shannon Dea addresses these questions and others while introducing readers to evidence and theoretical perspectives from a range of cultures and disciplines, and from sources spanning three millennia. Dea’s pluralistic and historically informed approach offers readers a timely background to current debates about sex and gender in the media, health sciences, and public policy.

Traditional diversity measures such as the Shannon entropy are generally computed from the species' relative abundance vector of a given community to the exclusion of species' absolute abundances. In this paper, I first mention some examples where the total information content associated with a given community may be more adequate than Shannon's average information content for a better understanding of ecosystem functioning. Next, I propose a parametric measure of statistical information that contains both Shannon's entropy and total information (...) content as special cases of this more general function. (shrink)

The phenomenon of reference is a very ordinary one. We refer to things in one manner or another in nearly every sentence we utter or thought we entertain. Yet within the analytic tradition, the phenomenon of reference has proved oddly resistant to philosophical clarification. Attempts to provide such clarification have met with a wide range of paradoxes and seemingly intractable aporias. The phenomenon has generally been treated in one of three ways: as an unexplained relation between words and entities of (...) the 'non-linguistic world'; as an internal feature of language lacking a genuinely relational structure; or as a 'mentalistic excrescence' that can and should be dissolved by logical analysis. I argue that none of these ways of accounting for the phenomenon does justice to it, and that the difficulties surrounding the problem of reference in the analytic tradition stem largely from certain reductive and metaphysical prejudices within that tradition. ;I attempt to demonstrate here that the phenomenon of reference can be adequately clarified only when its relational structure and its essential nature as an act are acknowledged. I argue that Husserl's phenomenology is uniquely able to meet this criterion, providing a clarification of the phenomenon while correcting the philosophical prejudices of the analytic account. That the phenomenological account of reference compares favorably to the analytic one is illustrated here by examining the difficulties that have attended analytic attempts to explain reference from Frege onward. These include the puzzle of informative identity statements, problems with substitution, naming, identification and description, Russell's Paradox, difficulties with occasional/indexical reference, 'intentional inexistence' and several others. Each of these problems can be readily solved with the phenomenological model. ;Though Husserl's phenomenology is certainly not without its own difficulties and limitations, it provides a much-needed correction to the myopia of the analytic tradition, particularly with respect to the irreducibly relational and act-driven structure of experience. The phenomenological clarification of reference, a phenomenon that issues directly from this structure, is uniquely illustrative of the value of such a correction. (shrink)

Positing implicit social cognitive processes is common in the social cognition literature. We see it in discussions of theories of mentalizing, empathy, and infants' social-cognitive capacities. However, there is little effort to articulate what counts as implicit social cognition in general, so theorizing about implicit social cognition is extremely disparate across each of these sub-domains.

In the section called “Observation of Nature” in the Phenomenology of Spirit, Hegel considers and criticizes a particular form of methodology which seeks final purposes by analogy. Through this methodology what is essential for thought is the recognition and demarcation of differentiae, which are imputed to natural objects as qualities by which things maintain their distinct and separate character - what Hegel calls their “being-for-self.” By these differentiae, then, the objects are categorized into types, or “natural kinds,” which, in turn, (...) are interpreted by natural philosophers according to a projected teleological system. Hegel’s critique is not aimed primarily at the categorization of objects, but at the method of interpretation used to characterize these categories as purposeful. In particular, Hegel is not criticizing the use of analogy as discussed in the biological writings of Aristotle, but the use of analogy by the transcendental idealists, especially Kant, who employs this method in the Critique of Judgment.

I defend a modified rights-based unjust threat account for morally justified killing in self-defense. Rights-based moral justifications for killing in self-defense presume that human beings have a right to defend themselves from unjust threats. An unjust threat account of self-defense says that this right is derived from an agent’s moral obligation to not pose a deadly threat to the defender. The failure to keep this moral obligation creates the moral asymmetry necessary to justify a defender killing the unjust threat in (...) self-defense. I argue that the other rights-based approaches explored here are unfair to the defender because they require her to prove moral fault in the threat. But then I suggest that the unjust threat account should be modified so that where the threat is non-culpable or only partially culpable, the defender should seek to share the cost and risk with the threat in order for both parties to survive.

Objective: Deep brain stimulation targeted to the ventral intermediate nucleus of the thalamus is effective for motor symptoms in essential tremor, but there is limited data on cognitive outcomes. We examined cognitive outcomes in a large cohort of ET DBS patients.Methods: In a retrospective analysis, we used repeated-measures ANOVA testing to examine whether the age of tremor onset, age at DBS surgery, hemisphere side implanted with lead, unilateral vs. bilateral implantations, and presence of surgical complications influenced the cognitive outcomes. Neuropsychological (...) outcomes of interest were verbal memory, executive functioning, working memory, language functioning, visuospatial functioning, and general cognitive function.Results: We identified 50 ET DBS patients; 29 males; the mean age of tremor onset was 35.84 years with a median age of 38 years. The mean age at DBS was 68.18 years. There were 37 unilateral 30 left, seven right, and 13 bilateral brain implantations. In the subgroup analysis, there was a significant interaction between assessment and age of tremor onset ; F = 4.47; p = 0.043 for working memory. The post hoc testing found improvements for younger onset ET. Similarly, there was a significant interaction between assessment and complications vs. no complications subgroups; F = 4.34; p = 0.043 for verbal memory with worsening scores seen for ET patients with complications. The remaining tests were not significant.Conclusion: In this large cohort of ET patients with, DBS was not accompanied by a significant decline in many cognitive domains. These outcomes were possibly related to the selection of patients with normal cognitive functioning before surgery, unilateral DBS implantations for the majority, and selection of patients with optimal response to DBS.

In this paper I evaluate embodied social cognition, embodied cognition’s account of how we understand others. I identify and evaluate three claims that motivate embodied social cognition. These claims are not specific to social cognition; they are general hypotheses about cognition. As such, they may be used in more general arguments for embodied cognition. I argue that we have good reasons to reject these claims. Thus, the case for embodied social cognition fails. Moreover, to the extent that (...) class='Hi'>general arguments for embodied cognition rest on these premises, they are correspondingly uncompelling. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:On the Need for a New Ethos of White AntiracismShannon SullivanWhite people in this country will have quite enough to do in learning how to accept and love themselves and each other, and when they have achieved this—which will not be tomorrow and may very well be never—the Negro problem will no longer exist, for it will no longer be needed.—James Baldwin, The Fire Next TimeIn his classic manifesto (...) on race, The Fire Next Time, James Baldwin passionately urges black people not to retaliate against white people by attempting to debase or dominate them in return. The reason is that doing so would harm black people most of all. As Baldwin (1963, 113) assures his readers,I am very much concerned that American Negroes achieve their freedom here in the United States. But I am also concerned for their dignity, for the health of their souls, and must oppose any attempt that Negroes may make to do to others what has been done to them. I think I know—we see it around us every day—the spiritual wasteland to which that road leads.... I would not like to see Negroes ever arrive at so wretched a condition.Likewise, when Martin Luther King Jr., urged his black church members to love their white enemies rather than return their racial hate, he did so because he believed that “hate distorts the personality of the hater. We usually think of what hate does for the individual hated or the individuals hated or the groups hated. But it is even more tragic, it is even more ruinous and injurious to the [End Page 21] individual who hates” (King 1957). While Baldwin was an avowed atheist and King a Christian minister, both warned of the devastating effects of white racism on “the souls of white folk,” and they pleaded and preached that black people should not stoop to white people’s debased level.1 Out of all the damage that white racism has done to African Americans and other people of color, the most damaging of all would be for it to turn them into the debilitated, deplorable people that white folk generally are.We might say that on Baldwin’s (and perhaps also King’s) view, white people are the truly “wretched of the earth” (Fanon 1965). It has been argued that white racism has cost white people their capability for intimacy, their affective lives, their authenticity, their sense of connection to other people, and their spiritual selves (Segrest 2001, 65). These claims are not an attempt to trump or erase the enormous physical, psychological, economic, spiritual, and other types of pain that white people have caused people of color around the world. They instead are a recognition that white people’s attempts to gain material riches and political power through the domination of people of color have impoverished and depleted their own souls. White people qua white are ill in that their racial habits largely have been built out of greed, hatred, jealousy, fear, and cruelty. Their psychosomatic health has suffered and continues to suffer because of their toxic racial identities.So much the worse for white people, we might think. But although understandable, this response would be misguided since white people’s psychosomatic depletion has implications for the well-being of others. Put succinctly, white people’s unhealthiness helps fuel their abuse and domination of people of color. It thus matters to struggles for racial justice whether white people are psychosomatically healthy and strong. It matters which affects, emotions, and passions fund white people’s actions in general, and their work for racial justice in particular. In this paper, I will draw from Friedrich Nietzsche, Teresa Brennan, and other scholars to explain the ontological and power-full aspects of affect, touching briefly on the toxicity of white guilt and shame and focusing especially on the healthiness of what Nietzsche calls a bestowing self-love. I will argue that in the context of white people’s contributions to racial justice movements, a positive effect of their bestowing self-love is that white people will be more likely and better able to clean up their own house...

i am honored to have the opportunity to think with Patricia Hill Collins about community as a political construct. Collins has argued that, like concepts of family and love, community often has been considered to be part of a nonpolitical sphere, something personal and private even as it is not individualistic. As feminists have shown, however, the personal is political, and as Collins urges, an intersectional understanding of the political can and also should apply to the concept of community. In (...) Collins's words, "instead of being a natural, apolitical space, or even an empty category that can be used for political purposes, the construct of community may lie at the heart of politics itself". The concept of... (shrink)

Women generally initiate, lead, and constitute the rank and file of environmental justice activism. However, there is little research on why there are comparatively so few men involved in these movements. Using the environmental justice movement in the Central Appalachian coalfields as a case study, we examine the ways that environmental justice activism is gendered, with a focus on how women’s and men’s identities both shape and constrain their involvement in gendered ways. The analysis relies on 20 interviews with women (...) and men grassroots activists working for environmental justice in the coalfields of Appalachia. We find that women draw on their identities as “mothers” and “Appalachians” to justify their activism, while the hegemonic masculinity of the region, which is tied to the coal industry, has the opposite effect on men, deterring their movement involvement. We explore the implications of these findings for understanding the relationship of gender to environmental justice activism. (shrink)

This study concerns the role of reflective judgment in both aesthetical appreciation and one’s self-understanding in relation to an unfamiliar other. Pillow’s thesis is that “Sublime reflection can provide … a model for a kind of interpretive response to the uncanny Other ‘outside’ our conceptual grasp. It thereby advances our sense-making pursuits even while eschewing unified, conceptual determination”. His principal focus is on Kant’s development of sublime judgment in the third Critique, where this form of reflective judgment becomes central to (...) Pillow’s greater theme: “I privilege sublime reflection in particular because it best models our interpretative search for meanings in things … furthermore, this reflection acknowledges the constitutive limitations of context-dependent understanding, its incapacity to determine fully the sense-making wholes it reaches to comprehend”. Hegel is drawn into the study ostensibly for two reasons. First, he has a more extensive, and determinate, idea of the content of aesthetical appreciation, whereas Kant adheres to a formalistic notion; second, Hegel is the foil for Pillow’s postmodern approach to the significance of reflective understanding. Since Hegel’s Aesthetics presents “the content of an art work … [in] a single fixed theme wholly available to conceptual analysis,” it stands opposed to Pillow’s view that the relation between the self-understanding subject and the other must remain “open” and foreign. Between and above Kant and Hegel floats Lyotard whose deconstructionist work on practical reason forms the impetus in Pillow’s study. (shrink)

In the twenty-first century, 70.6 percent of Americans self-identify as Christians,1 58 percent of them still segregate themselves by race on Sunday mornings, and white Protestants make up the majority of this 58 percent.2 These facts belie the claim, popularized after Barack Obama's 2008 presidential election, that America is living in a postracial society3 And yet, the role played by religion in white people's lived experiences of race, racism, and white class privilege in the United States tends to be neglected (...) by philosophers and religious studies scholars, except perhaps when considering white supremacist groups such as the Ku Klux Klan.4 Contemporary philosophy is secular in a way that generally excludes and...

"'Religion' as James remarks in a letter of 1897 'is the great interest of my life.'". In the early chapters of this fresh, healthy study of James's thinking about the realm of the religious, O'Connell gathers evidence from James's essays and letters as well as the testimonial evidence in Ralph Barton Perry's biography to argue that despite his early training in physiology and medicine, James viewed his fundamental task as the interpretation of such notions as "courage," "strenuous mood," "wager of (...) belief," and the "passional side of thought." Yet O'Connell's work surpasses intellectual history and offers a truly philosophical conversation. (shrink)

Categorical logic has shown that modern logic is essentially the logic of subsets (or "subobjects"). Partitions are dual to subsets so there is a dual logic of partitions where a "distinction" [an ordered pair of distinct elements (u,u′) from the universe U ] is dual to an "element". An element being in a subset is analogous to a partition π on U making a distinction, i.e., if u and u′ were in different blocks of π. Subset logic leads to finite (...) probability theory by taking the (Laplacian) probability as the normalized size of each subset-event of a finite universe. The analogous step in the logic of partitions is to assign to a partition the number of distinctions made by a partition normalized by the total number of ordered pairs |U|² from the finite universe. That yields a notion of "logical entropy" for partitions and a "logical information theory." The logical theory directly counts the (normalized) number of distinctions in a partition while Shannon's theory gives the average number of binary partitions needed to make those same distinctions. Thus the logical theory is seen as providing a conceptual underpinning for Shannon's theory based on the logical notion of "distinctions.". (shrink)

In pediatric critical care, nurses are the primary caregivers for critically ill children and are particularly vulnerable to moral distress. There is limited evidence on what approaches are effective to minimize moral distress among these nurses. To identify intervention attributes that critical care nurses with moral distress histories deem important to develop a moral distress intervention. We used a qualitative description approach. Participants were recruited using purposive sampling between October 2020 to May 2021 from pediatric critical care units in a (...) western Canadian province. We conducted individual semi-structured interviews via Zoom. A total of 10 registered nurses participated in the study. Four main themes were identified: (1) “I’m sorry, there’s nothing else”: increasing supports for patients and families; (2) “someone will commit suicide”: improving supports for nurses: (3) “Everyone needs to be heard”: improving patient care communication; and (4) “I didn’t see it coming”: providing education to mitigate moral distress. Most participants stated they wanted an intervention to improve communication among the healthcare team and noted changes to unit practices that could decrease moral distress. This is the first study that asks nurses what is needed to minimize their moral distress. Although there are multiple strategies in place to help nurses with difficult aspects of their work, additional strategies are needed to help nurses experiencing moral distress. Moving the research focus from identifying moral distress towards developing effective interventions is needed. Identifying what nurses need is critical to develop effective moral distress interventions. (shrink)

Amartya Sen argues that sectarian discord and violence are fueled by confusion about the nature of identity, including the pervasive tendency to see ourselves as members of singular social groups standing in opposition to other groups (e.g. Democrat vs. Republican, Muslim vs. Christian, etc.). Sen defends an alternative model of identity, according to which we all inevitably belong to a plurality of discrete identity groups (including ethnicities, classes, genders, races, religions, careers, hobbies, etc.) and are obligated to choose, in any (...) given context, which among our multiple affiliations to prioritize. While Sen’s model of discrete identity prioritization is a clear advance over single-factor accounts, it overlooks significant lessons about identity from over 150 years of scholarship by feminists of color. In ignoring the experiences of women of color, Sen’s model falsely assumes that identities are in-principle separable for the purposes of practical deliberation; and, in obligating individuals to make such identity-based “reasoned choices,” Sen’s model forces those with multiply marginalized identities to choose from a set of externally defined identity options, none of which sufficiently captures their experiences.

This book covers Schelling's development from the Early Writings through to his System of Transcendental Idealism, and finally Schelling's Philosophy and Religion and Philosophy of Art. Schneider traces Schelling's "way of thinking" beginning with his attempt at a transcendental philosophy centering on the Ego as the primordial principle for the cognition of being, through his explication of the unity of being and thinking in an intellectual intuition, to finally, Schelling's highest achievement in the conception of thinking as art. Art is (...) here considered as the organon or "vehicle" for a philosophy of religion. Schneider contends that this development is a consistent, continuous one devoid of the contradictions that several of the modern commentators attribute to Schelling. Schneider points out that as early as 1794 Schelling saw the central problem in transcendental philosophy as explicating the "eternal in us" and how it can be brought to light through a philosophical methodology. However, Schneider further contends that it was not until Schelling established his philosophy of identity in the System of Transcendental Idealism that he found the method for uncovering the eternal dimensions within consciousness. This discovery was made possible because intellectual intuition, which for the first time was fully worked out in the System, is seen as the apprehension of the invariable unity within the plurality and variability of temporal consciousness. The form of the invariable is the absolute "I" or the primordial self, while that which presents itself in time is the empirical "I" with its content of thought, namely, sensuous intuition. Cognition is accomplished at the point of unity wherein the world in its finitude is "framed" by the transcendental unity of the "I" in pure act. (shrink)

BackgroundAlthough patient advocates have developed templates for standard consent forms, evaluating patient preferences for first in human (FIH) and window of opportunity (Window) trial consent forms is critical due to their unique risks. FIH trials are the initial use of a novel compound in study participants. In contrast, Window trials give an investigational agent over a fixed duration to treatment naïve patients in the time between diagnosis and standard of care (SOC) surgery. Our goal was to determine the patient-preferred presentation (...) of important information in consent forms for these trials.MethodsThe study consisted of two phases: (1) analyses of oncology FIH and Window consents; (2) interviews of trial participants. FIH consent forms were analyzed for the location(s) of information stating that the study drug has not been tested in humans (FIH information); Window consents were analyzed for the location(s) of information stating the trial may delay SOC surgery (delay information). Participants were asked about their preferred placement of the information in their own trial’s consent form. The location of information in the consent forms was compared to the participants’ suggestions for placement. Results34 [17 FIH; 17 Window] of 42(81%) cancer patients approached participated. 25 consents [20 FIH; 5 Window] were analyzed. 19/20 FIH consent forms included FIH information, and 4/5 Window consent forms included delay information. 19/20(95%) FIH consent forms contained FIH information in the risks section 12/17(71%) patients preferred the same. Fourteen (82%) patients wanted FIH information in the purpose, but only 5(25%) consents mentioned it there. 9/17(53%) Window patients preferred delay information to be located early in the consent, before the “Risks” section. 3/5(60%) consents did this.ConclusionsDesigning consents that reflect patient preferences more accurately is essential for ethical informed consent; however, a one-size fits all approach will not accurately capture patient preferences. We found that preferences differed for FIH and Window trial consents, though for both, patients preferred key risk information early in the consent. Next steps include determining if FIH and Window consent templates improve understanding. (shrink)

Sports are an excellent venue for demonstrating evolutionary principles to audiences not familiar with academic research. Team sports and sports fandom feature dynamics of in-group loyalty and intergroup competition, influenced by our evolved coalitional psychology. We predicted that reactions to expressions signaling mutual team/group allegiance would vary as a function of the territorial context. Reactions should become more prevalent, positive, and enthusiastic as one moves from the home territory to a contested area, and from a contested area to a rival’s (...) territory during active rival engagement. We also predicted that men would be more responsive than women based on sex differences in evolved coalitional psychology. The research team visited public places immediately prior to 2016–2017 collegiate football and basketball games. A male research confederate wore a sweatshirt displaying the logo of one of the competing university teams and vocalized the team’s most popular slogan when he saw a fan displaying similar logos. Observers followed 5 m behind, recording reactions and response positivity/enthusiasm. Reaction tone was most positive in the rival territory, least positive in the home territory, and intermediate in the periphery and contested territory. Rates of “no reaction” were lowest in the rival territory but were highest in the periphery. Men had higher reaction rates and more positive and enthusiastic reaction tones than women. Reactions generally followed predictions based on expected signal value. This project provides evidence that coalitional psychology influences dynamics related to university sports team rivalries and that context matters for expressions of alliance. (shrink)

This study has two purposes. First, the study evaluates the reliability of self-reports of argumentativeness by comparing self-reported argumentativeness with two other reports of the same target: evaluations by friends and evaluations by intimates. Second, the study examines whether particular characteristics presage a larger or smaller disparity in different reporters’ reports. We found the reliability of both the approach and avoidance subscales to be acceptable for the intimate partner’s responses, but only marginally acceptable when the scale was answered by a (...) friend; on a basic level, we did not find individuals over or under-estimating their level of argumentativeness, self-over and under estimating has limited impact on the self-reporting of argumentativeness, though males are more likely to over-report argumentativeness; and while relational history had little effect on other-reports, there were effects for same-sex couples that should be further explored.

This work is a concise study of the central concepts in Wittgenstein's later philosophy of psychology. Schulte uses Wittgenstein's manuscripts from 1945-49 to illuminate central arguments and ideas more accessible through these manuscripts than through the published texts. Specifically Schulte is concerned with manuscripts 130-8 which deal with the logic of psychological concepts, the concepts of thinking, understanding, sensation, and perception, as well as with philosophical method, philosophical argumentation, and an analysis of conditional statements. Also included in the manuscripts are (...) remarks on aesthetics and ethics. Schulte's book clarifies Wittgenstein's thoughts on these subjects and connects these developments in his thinking to his work in the late 1940s. Experience and Expression includes discussion of language games, the classifications of psychological concepts, expression, experience, objects of vision, memory, and emotion, as well as belief, supposition and assertion.

In this excellent introductory study, Schulte provides a clear, concise account of Wittgenstein's life and works. Schulte captures the flavor of Wittgenstein's life: the passion and intensity, as well as the desire for solitude and loneliness which inform his writings. The first chapter presents a sensitive and thoughtful picture of Wittgenstein as a man who loved to make things. We suffer with Wittgenstein as he lives to see the suicides of three of his four brothers and contemplates suicide himself, and (...) we feel gladdened when an uncle persuades Wittgenstein to choose a creative endeavor--the writing of his first book. Schulte portrays Wittgenstein in search of the "decent" life. His book is to be commended for introducing us to the Wittgenstein whose forceful personality so markedly colors his work. (shrink)

People across the world seek out beautiful sounds in nature, such as a babbling brook or a nightingale song, for positive human experiences. However, it is unclear whether this positive aesthetic response is driven by a preference for the perceptual features typical of nature sounds versus a higher‐order association of nature with beauty. To test these hypotheses, participants provided aesthetic judgments for nature and urban soundscapes that varied on ease of recognition. Results demonstrated that the aesthetic preference for nature soundscapes (...) was eliminated for the sounds hardest to recognize, and moreover the relationship between aesthetic ratings and several measured acoustic features significantly changed as a function of recognition. In a follow‐up experiment, requiring participants to classify these difficult‐to‐identify sounds into nature or urban categories resulted in a robust preference for nature sounds and a relationship between aesthetic ratings and our measured acoustic features that was more typical of easy‐to‐identify sounds. This pattern of results was replicated with computer‐generated artificial noises, which acoustically shared properties with the nature and urban soundscapes but by definition did not come from these environments. Taken together, these results support the conclusion that the recognition of a sound as either natural or urban dynamically organizes the relationship between aesthetic preference and perceptual features and that these preferences are not inherent to the acoustic features. Implications for nature's role in cognitive and affective restoration are discussed. (shrink)

Bloom's eloquent and comprehensive treatment of early word learning holds that social intention is foundational for language development. While we generally support his thesis, we call into question two of his proposals: (1) that attention to social information in the environment implies social intent, and (2) that infants are sensitive to social intent at the very beginnings of word learning.

Morality can help guide behavior and facilitate relationships. Although moral judgments by autistic people are similar to neurotypical individuals, many researchers argue that subtle differences signify deficits in autistic individuals. Moral foundation theory describes moral judgments in terms of differences rather than deficits. The current research, aimed at assessing autistic individuals’ moral inclinations using Haidt’s framework, was co-designed with autistic community members. Our aim was to describe autistic moral thinking from a strengths-based perspective while acknowledging differences that may pose interpersonal (...) challenges among autistic youth. We assessed 25 autistic and 23 neurotypical children’s moral judgments using the Moral Foundations Questionnaire for Kids. We used semi-structured interviews and qualitative analysis with a subset of participants to describe children’s moral reasoning. Analyses suggested that autistic and neurotypical children make similar judgments about moral transgressions across all five moral foundations. General linear mixed modeling showed that the greatest predictor of recommending punishment was how bad children deemed moral transgressions to be. We also found a trend that autistic children were more likely to recommend punishment for harmless norms violations than were neurotypical children. Future research could use longitudinal methods to understand the development of moral judgments among autistic and neurotypical children. (shrink)

This paper is a technical study of the systematic observations and computations made by Muḥyī al-Dīn al-Maghribī (d. 1283) at the Maragha observatory (north-western Iran, c. 1259–1320) in order to newly determine the parameters of the Ptolemaic lunar model, as explained in his Talkhīṣ al-majisṭī, “Compendium of the Almagest.” He used three lunar eclipses on March 7, 1262, April 7, 1270, and January 24, 1274, in order to measure the lunar epicycle radius and mean motions; an observation on April 20, (...) 1264, to determine the lunar eccentricity; an observation on August 29, 1264, to test the model; and another on March 15, 1262, for measuring the lunar parallax. In the second period of activity at the Maragha observatory, Shams al-Dīn Muḥammad al-Wābkanawī (c. 1254–1320) adopted all of al-Maghribī’s parameter values in his Zīj, but decreased his value for the mean longitude of the moon at epoch by 0;13,11∘\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$^{\circ }$$\end{document}.
