The stratum-specific treatment effect function is a random variable giving the average treatment effect (ATE) for a randomly drawn stratum of potential confounders a clinician may use to assign treatment. In addition to the ATE, the variance of the stratum-specific treatment effect function is fundamental in determining the heterogeneity of treatment effect values. We offer a non-parametric plug-in estimator, the targeted maximum likelihood estimator (TMLE) and the cross-validated TMLE (CV-TMLE), to simultaneously estimate both the average and variance of the stratum-specific (...) treatment effect function. The CV-TMLE is preferable because it guarantees asymptotic efficiency under two conditions without needing entropy conditions on the initial fits of the outcome model and treatment mechanism, as required by TMLE. Particularly, in circumstances where data adaptive fitting methods are very important to eliminate bias but hold no guarantee of satisfying the entropy condition, we show that the CV-TMLE sampling distributions maintain normality with a lower mean squared error than TMLE. In addition to verifying the theoretical properties of TMLE and CV-TMLE through simulations, we highlight some of the challenges in estimating the variance of the treatment effect, which lack double robustness and might be biased if the true variance is small and sample size insufficient.

One of the clearest signs that Psychology has impacted popular culture is the public’s familiarity with the Rorschach ink-blot test. An excellent example of the Rorschach in popular culture can be found in Watchmen, the comic/graphic novel written by Alan Moore and Dave Gibbons. In the mid-20th century Psychology had an especially contentious relationship with comics; some psychologists were very anxious about the impact comics had on young people, whereas others wrote comics to subvert dominant norms about gender and (...) sexuality. Yet historians of Psychology have had almost nothing to say about this popular and critically acclaimed novel. We read Watchmen here for its narratives that most concern the history of Psychology. We focus on such themes as anti-psychiatry, sexual violence, homophobia, lesbian erasure and social psychological research on bystander intervention. We argue it is possible to align Psychology and comics more closely despite their sometimes contentious history. In doing so we demonstrate the active role of the public in the history of the Rorschach, and the public engagement of Psychology via comics, and also reveal what is possible when historians consider comics within their histories.

Some exceptional and surprising mistakes of scholarship made in the writings of a number of feminist academics (Ruth Bleier, Ruth Hubbard, Susan Bordo, Sandra Harding, and Rae Langton) are examined in detail. This essay offers the psychological hypothesis that these mistakes were the result of political passion and concludes with some remarks about the ability of the social sciences to study the effect of the politics of the researcher on the quality of his or her research.

Feminists acknowledge that making science is a social process and that scientific laws and the "facts" of science reflect the interests of the university-educated, economically privileged, predominantly white men who have produced them. We also recognize that knowledge about nature is created by an interplay between objectivity and subjectivity, but we often do not credit sufficiently the ways women's traditional activities in home, garden, and sickroom have contributed to understanding nature.

Technological innovations have transformed our culture's ways of thinking about procreation and pregnancy, and about health and illness. Until not so long ago, the ongoing processes inside women's bodies as they gestated their future babies was up to conjecture. In Western industrialized countries, pregnancy was the slow process during which a woman gradually came to accept the fact that she was sharing her bodily space with another, and that now, as well as after the baby emerged, the primary responsibility for (...) that new person's survival would be hers.

Challenging topics in museums can guide museum professionals in developing modern methods of displaying their heritage, but also in offering reinterpretations of existing collections. The public also looks for challenging topics—injustice, loss, pain, or death—and many museums manage to attract visitors by offering them places to debate, reflect, or take action. These topics, if presented in an exhibition, could engage practising artists in an ideological exchange with the museum institution. Our statement is that artists with curatorial interest can scrutinise the (...) ways in which cultural heritage is revealed or interpreted for the contemporary public. The uncomfortable or uncertain aspects of recent and contemporary history are of great interest for contemporary artists and we assume that the Communist era in Romania could be further interpreted by artists in future museum places.

(1) The induced colours led to perceptual grouping and pop-out, (2) a grapheme rendered invisible through ‘crowding’ or lateral masking induced synaesthetic colours — a form of blindsight — and (3) peripherally presented graphemes did not induce colours even when they were clearly visible. Taken collectively, these and other experiments prove conclusively that synaesthesia is a genuine percep- tual phenomenon, not an effect based on memory associations from childhood or on vague metaphorical speech. We identify different subtypes of number–colour synaesthesia (...) and propose that they are caused by hyperconnectivity between col- our and number areas at different stages in processing; lower synaesthetes may have cross-wiring (or cross-activation) within the fusiform gyrus, whereas higher synaesthetes may have cross-activation in the angular gyrus. This hyperconnec- tivity might be caused by a genetic mutation that causes defective pruning of con- nections between brain maps. The mutation may further be expressed selectively (due to transcription factors) in the fusiform or angular gyri, and this may explain the existence of different forms of synaesthesia. If expressed very diffusely, there may be extensive cross-wiring between brain regions that represent abstract concepts, which would explain the link between creativity, metaphor and synaesthesia (and the higher incidence of synaesthesia among artists and poets). Also, hyperconnectivity between the sensory cortex and amygdala would explain the heightened aversion synaesthetes experience when seeing numbers printed in the ‘wrong’ colour. Lastly, kindling (induced hyperconnectivity in the temporal lobes of temporal lobe epilepsy [TLE] patients) may explain the purported higher incidence of synaesthesia in these patients. We conclude with a synaesthesia-based theory. (shrink)

Many explanations in science make use of mathematics. But are there cases where the mathematical component of a scientific explanation is explanatory in its own right? This issue of mathematical explanations in science has been for the most part neglected. I argue that there are genuine mathematical explanations in science, and present in some detail an example of such an explanation, taken from evolutionary biology, involving periodical cicadas. I also indicate how the answer to my title question impacts on broader (...) issues in the philosophy of mathematics; in particular it may help platonists respond to a recent challenge by Joseph Melia concerning the force of the Indispensability Argument.

In spite of a powerful tradition, more than two thousand years old, that in a valid argument the premises must be relevant to the conclusion, twentieth-century logicians neglected the concept of relevance until the publication of Volume I of this monumental work. Since that time relevance logic has achieved an important place in the field of philosophy: Volume II of Entailment brings to a conclusion a powerful and authoritative presentation of the subject by most of the top people working in (...) the area. Originally the aim of Volume II was simply to cover certain topics not treated in the first volume--quantification, for example--or to extend the coverage of certain topics, such as semantics. However, because of the technical progress that has occurred since the publication of the first volume, Volume II now includes other material. The book contains the work of Alasdair Urquhart, who has shown that the principal sentential systems of relevance logic are undecidable, and of Kit Fine, who has demonstrated that, although the first-order systems are incomplete with respect to the conjectured constant domain semantics, they are still complete with respect to a semantics based on "arbitrary objects." Also presented is important work by the other contributing authors, who are Daniel Cohen, Steven Giambrone, Dorothy L. Grover, Anil Gupta, Glen Helman, Errol P. Martin, Michael A. McRobbie, and Stuart Shapiro. Robert G. Wolf's bibliography of 3000 items is a valuable addition to the volume. (shrink)

'Working Memory, Thought, and Action' is the magnum opus of one of the most influential cognitive psychologists of the past 50 years. This new volume on the model he created discusses the developments that have occurred within the model in the past twenty years, and places it within a broader context.

Does mathematics ever play an explanatory role in science? If so then this opens the way for scientific realists to argue for the existence of mathematical entities using inference to the best explanation. Elsewhere I have argued, using a case study involving the prime-numbered life cycles of periodical cicadas, that there are examples of indispensable mathematical explanations of purely physical phenomena. In this paper I respond to objections to this claim that have been made by various philosophers, and I discuss (...) potential future directions of research for each side in the debate over the existence of abstract mathematical objects.

This study tested four theoretical models of leadership with data from the ethnographic record. The first was a game-theoretical model of leadership in collective actions, in which followers prefer and reward a leader who monitors and sanctions free-riders as group size increases. The second was the dominance model, in which dominant leaders threaten followers with physical or social harm. The third, the prestige model, suggests leaders with valued skills and expertise are chosen by followers who strive to emulate them. The (...) fourth proposes that in small-scale, kin-based societies, men with high neural capital are best able to achieve and maintain positions of social influence (e.g., as headmen) and thereby often become polygynous and have more offspring than other men, which positively selects for greater neural capital. Using multiple search strategies we identified more than 1000 texts relevant to leadership in the Probability Sample of 60 cultures from the Human Relations Area Files (HRAF). We operationalized the model with variables and then coded all retrieved text records on the presence or absence of evidence for each of these 24 variables. We found mixed support for the collective action model, broad support for components of the prestige leadership style and the importance of neural capital and polygyny among leaders, but more limited support for the dominance leadership style. We found little evidence, however, of emulation of, or prestige-biased learning toward, leaders. We found that improving collective actions, having expertise, providing counsel, and being respected, having high neural capital, and being polygynous are common properties of leaders, which warrants a synthesis of the collective action, prestige, and neural capital and reproductive skew models. We sketch one such synthesis involving high-quality decision-making and other computational services. (shrink)

We studied two otherwise normal, synaesthetic subjects who `saw' a speci¢c colour every time they saw a speci¢c number or letter. We conducted four experiments in order to show that this was a genuine perceptual experience rather than merely a memory association. (i)The synaesthetically induced colours could lead to perceptual grouping, even though the inducing numerals or letters did not. (ii)Synaesthetically induced colours were not experienced if the graphemes were presented peripherally. (iii)Roman numerals were ine¡ective: the actual number grapheme was (...) required. (iv)If two graphemes were alternated the induced colours were also seen in alternation. However, colours were no longer experienced if the graphemes were alternated at more than 4 Hz. We propose that grapheme colour synaesthesia arises from `cross-wiring' between the `colour centre' (area V4 or V8)and the `number area', both of which lie in the fusiform gyrus. We also suggest a similar explanation for the representation of metaphors in the brain: hence, the higher incidence of synaesthesia among artists and poets. (shrink)

We discuss a recent attempt by Chris Daly and Simon Langford to do away with mathematical explanations of physical phenomena. Daly and Langford suggest that mathematics merely indexes parts of the physical world, and on this understanding of the role of mathematics in science, there is no need to countenance mathematical explanation of physical facts. We argue that their strategy is at best a sketch and only looks plausible in simple cases. We also draw attention to how frequently Daly and (...) Langford find themselves in conflict with mathematical and scientific practice. (shrink)

Philosophers of mathematics have become increasingly interested in the explanatory role of mathematics in empirical science, in the context of new versions of the Quinean ‘Indispensability Argument’ which employ inference to the best explanation for the existence of abstract mathematical objects. However, little attention has been paid to analysing the nature of the explanatory relation involved in these mathematical explanations in science (MES). In this paper, I attack the only articulated account of MES in the literature (an account sketched by (...) Mark Steiner), according to which a genuine MES incorporates an explanatory proof of the mathematical result being used. The central case study involves an explanation for why bees build the cells of their honeycombs in the shape of hexagons. I make a distinction between two kinds of MES, mathematics-driven explanation in science and science-driven mathematical explanation, and argue that it is the second category which is both scientifically and philosophical more central. I conclude that the explanatory relation involved in MES is genuinely scientific and hence that the phenomenon of MES poses a challenge to general accounts of scientific explanation. (shrink)

This article supplements our earlier paper on synaesthesia published in JCS (Ramachandran & Hubbard, 2001a). We discuss the phenomenology of synaesthesia in greater detail, raise several new questions that have emerged from recent studies, and suggest some tentative answers to these questions.

The desire to minimize the number of individual new entities postulated is often referred to as quantitative parsimony. Its influence on the default hypotheses formulated by scientists seems undeniable. I argue that there is a wide class of cases for which the preference for quantitatively parsimonious hypotheses is demonstrably rational. The justification, in a nutshell, is that such hypotheses have greater explanatory power than less parsimonious alternatives. My analysis is restricted to a class of cases I shall refer to as (...) additive. Such cases involve the postulation of a collection of qualitatively identical individual objects which collectively explain some particular observed phenomenon. Especially clear examples of this sort occur in particle physics.1Introduction2Particle physics: a case study3Three kinds of simplicity4Explanatory power5Explanation and non‐observation6Parsimony and scientific methodology7Conclusions.

Alan Bailey offers a clear and vigorous exposition and defence of the philosophy of Sextus Empiricus, one of the most influential of ancient thinkers, the father of philosophical scepticism. The subsequent sceptical tradition in philosophy has not done justice to Sextus: his views stand up today as remarkably insightful, offering a fruitful way to approach issues of knowledge, understanding, belief, and rationality. Bailey's refreshing presentation of Sextus to a modern philosophical readership rescues scepticism from the sceptics.

A survey of the recent literature suggests that physicians should engage religious patients on religious grounds when the patient cites religious considerations for a medical decision. We offer two arguments that physicians ought to avoid engaging patients in this manner. The first is the Public Reason Argument. We explain why physicians are relevantly akin to public officials. This suggests that it is not the physician’s proper role to engage in religious deliberation. This is because the public character of a physician’s (...) role binds him/her to public reason, which precludes the use of religious considerations. The second argument is the Fiduciary Argument. We show that the patient-physician relationship is a fiduciary relationship, which suggests that the patient has the clinical expectation that physicians limit themselves to medical considerations. Since engaging in religious deliberations lies outside this set of considerations, such engagement undermines trust and therefore damages the patient-physician relationship. (shrink)

According to one popular nominalist picture, even when mathematics features indispensably in scientific explanations, this mathematics plays only a purely representational role: physical facts are represented, and these exclusively carry the explanatory load. I think that this view is mistaken, and that there are cases where mathematics itself plays an explanatory role. I distinguish two kinds of explanatory generality: scope generality and topic generality. Using the well-known periodical-cicada example, and also a new case study involving bicycle gears, I argue that (...) what is picked out by the mathematics are structural facts that go beyond any specific physical facts.

Comparative constructions form two classes, those that permit direct comparisons (comparisons of measurements as in Seymour is taller than he is wide) and those that only allow indirect comparisons (comparisons of relative positions on separate scales as in Esme is more beautiful than Einstein is intelligent). In contrast with other semantic theories, this paper proposes that the interpretation of the comparative morpheme remains the same whether it appears in sentences that compare individuals directly or indirectly. To develop a unified account, (...) I suggest that all comparisons (whether in terms of height, intelligence or beauty) involve a scale of universal degrees that are isomorphic to the rational (fractional) numbers between 0 and 1. Crucial to a unified treatment, the connection between the individuals being compared and universal degrees involves two steps. First individuals are mapped to a value on a primary scale that ranks individuals with respect to the gradable property (whether it be height, beauty or intelligence). Second, the value on the primary scale is mapped to a universal degree that encodes the value’s relative position on the primary scale. Direct comparison results if measurements such as seven feet participate in the primary scale (as in Seven feet is tall). Otherwise the result is an indirect comparison. (shrink)

If embodied models no longer address the symbol grounding problem and a conceptual system can step in and resolve categorizations when embodied simulations fail, then perhaps the next step in theory-building is to isolate the unique contributions of embodied simulation.

First published in 1967, _Writing and Difference_, a collection of Jacques Derrida's essays written between 1959 and 1966, has become a landmark of contemporary French thought. In it we find Derrida at work on his systematic deconstruction of Western metaphysics. The book's first half, which includes the celebrated essay on Descartes and Foucault, shows the development of Derrida's method of deconstruction. In these essays, Derrida demonstrates the traditional nature of some purportedly nontraditional currents of modern thought—one of his main targets (...) being the way in which "structuralism" unwittingly repeats metaphysical concepts in its use of linguistic models. The second half of the book contains some of Derrida's most compelling analyses of why and how metaphysical thinking must exclude writing from its conception of language, finally showing metaphysics to be constituted by this exclusion. These essays on Artaud, Freud, Bataille, Hegel, and Lévi-Strauss have served as introductions to Derrida's notions of writing and _différence_—the untranslatable formulation of a nonmetaphysical "concept" that does not exclude writing—for almost a generation of students of literature, philosophy, and psychoanalysis. _Writing and Difference_ reveals the unacknowledged program that makes thought itself possible. In analyzing the contradictions inherent in this program, Derrida foes on to develop new ways of thinking, reading, and writing,—new ways based on the most complete and rigorous understanding of the old ways. Scholars and students from all disciplines will find _Writing and Difference_ an excellent introduction to perhaps the most challenging of contemporary French thinkers—challenging because Derrida questions thought as we know it.

Symbolic thought is what makes us human. Claude Lévi-Strauss stated that we can never know the genesis of symbolic thought, but in this powerful new study Alan Barnard argues that we can. Continuing the line of analysis initiated in Social Anthropology and Human Origins, Genesis of Symbolic Thought applies ideas from social anthropology, old and new, to understand some of the areas also being explored in fields as diverse as archaeology, linguistics, genetics and neuroscience. Barnard aims to answer questions (...) including: when and why did language come into being? What was the earliest religion? And what form did social organization take before humanity dispersed from the African continent? Rejecting the notion of hunter-gatherers as 'primitive', Barnard hails the great sophistication of the complex means of their linguistic and symbolic expression and places the possible origin of symbolic thought at as early as 130,000 years ago.
