Pregnancy involves puzzling aversions to nutritious foods. Although studies generally support the hypotheses that such aversions are evolved mechanisms to protect the fetus from toxins and/or pathogens, other factors, such as resource scarcity and psychological distress, have not been investigated as often. In addition, many studies have focused on populations with high-quality diets and low infectious disease burden, conditions that diverge from the putative evolutionary environment favoring fetal protection mechanisms. This study tests the fetal protection, resource scarcity, and psychological distress (...) hypotheses of food aversions in a resource-constrained population with high infectious disease burden. The role of culture is also explored. In the first of two studies in Tamil Nadu, India, we investigated cultural explanations of pregnancy diet among non-pregnant women (N = 54). In the second study, we conducted structured interviews with pregnant women (N = 94) to determine their cravings and aversions, resource scarcity, indices of pathogen exposure, immune activation, psychological distress, and emic causes of aversions. Study 1 found that fruits were the most commonly reported food that pregnant women should avoid because of their harmful effects on infants. Study 2 found modest support for the fetal protection hypothesis for food aversions. It also found that pregnant women most commonly avoided fruits as well as “black” and “hot” foods. Aversions were primarily acquired through learning and focused on protecting the infant from harm. Our findings provide modest support for the fetal protection hypothesis and surprisingly strong support for the influence of cultural norms and learning on dietary aversions in pregnancy. (shrink)

Fasting during pregnancy is an enigma: why would a woman restrict her food intake during a period of increased nutritional need? Relative to the costs to healthy individuals who are not pregnant, the physiological costs of fasting in pregnancy are amplified, with intrauterine death being one possible outcome. Given these physiological costs, the question arises as to the socioecological factors that give rise to fasting during pregnancy. There has been little formal research regarding the emic perceptions and socioecological factors associated (...) with such fasting. This study therefore took an emic approach and investigated the types of fasts that are common in pregnancy, women’s perceptions of the consequences of fasting, and the socioecological models of pregnancy fasting in three Indian communities. This cross-sectional study took place in Bhubaneshwar, Odisha state, and Mysore, Karnataka state, among two populations of Hindu women and one population of Muslim women (_N_ = 85). In total, 64% of women fasted in prior pregnancies. Findings revealed variation in the number and types of fasts that are common in pregnancy across the three communities. Each community reported differences in positive and negative consequences of fasting, with varied emphasis on reproductive health, religiosity, and general health and well-being. Finally, quantitative analyses indicated that the best-fitting model for fasting during pregnancy was religiosity, and the poorest-fitting models were resource scarcity and general health. This study provides insight into motivations for such fasting and highlights the need to investigate the relationship between supernatural beliefs and maternal–fetal protection further, as well as social functions of pregnancy fasting within the family and community.

HIV stigma and fears surrounding the disease pose a challenge for public health interventions, particularly those that target pregnant women. In order to reduce stigma and improve the lives of vulnerable populations, researchers have recognized a need to integrate different types of support at various levels. To better inform HIV interventions, the current study draws on social-ecological and evolutionary theories of reproduction to predict stigma and fear of contracting HIV among pregnant women in South India. The aims of this study (...) were twofold: compare the social-ecological model to a modified maternal-fetal protection model and test a combined model that included strong predictors from each model. The study took place in 2008–2011 in Mysore District, Karnataka, India. Using data from a cross-sectional survey and biological indicators of health, we statistically modeled social-ecological variables representing individual, interpersonal, and community/institutional levels. Participants were 645 pregnant women. The social-ecological and combined models were the best-fitting models for HIV-related stigma, and the combined model was the best fit for HIV-related fear. Our findings suggest that combining reproductive life history factors along with individual, interpersonal, and community/institutional factors are significant indicators of HIV-related stigma and fear. Results of this study support a multifaceted approach to intervention development for HIV-related stigma and fear. The combined model in this study can be used as a predictive model for future research focused on HIV stigma and fear, with the intent that dual consideration of social-ecological and evolutionary theories will improve public health communication efforts.

The paper extends the framework of outcomes in branching space-time (Kowalski and Placek [1999]) by assigning probabilities to outcomes of events, where these probabilities are interpreted either epistemically or as weighted possibilities. In resulting models I define the notion of common cause of correlated outcomes of a single event, and investigate which setups allow for the introduction of common causes. It turns out that a deterministic common cause can always be introduced, but (surprisingly) only special setups permit the introduction (...) of truly stochastic common causes. I analyse next the Bell-Aspect experiment and derive the Bell-CH inequalities. I observe that we postulate there not a common cause for outcomes of a single event but rather a common common cause that accounts for outcomes of many events, where 'events' mean 'measurements with (different) directions of polarization'. Since the inequalities are violated, I claim that no causal story can be told about the Bell correlations, where causality is subliminal and restricted by screening-off condition. Similarly, given certain intuitive principles, no deterministic story can be told about these correlations. (shrink)

The paper investigates, in the framework of branching space–times, whether an infinite EPR-like correlation which does not involve finite EPR-like correlations is possible.

Indeterminism, understood as a notion that an event may be continued in a few alternative ways, invokes the question what a region of chanciness looks like. We concern ourselves with its topological and spatiotemporal aspects, abstracting from the nature or mechanism of chancy processes. We first argue that the question arises in Montague-Lewis-Earman conceptualization of indeterminism as well as in the branching tradition of Prior, Thomason and Belnap. As the resources of the former school are not rich enough to study (...) topological issues, we investigate the question in the framework of branching space-times of Belnap (Synthese 92:385–434, 1992). We introduce a topology on a branching model as well as a topology on a history in a branching model. We define light-cones and assume four conditions that guarantee the light-cones so defined behave like light-cones of physical space-times. From among various topological separation properties that are relevant to our question, we investigate the Hausdorff property. We prove that each history in a branching model satisfies the Hausdorff property. As for the satisfaction of the Hausdorff property in the entire branching model, we prove that it is related to the phenomenon of passive indeterminism, which we describe in detail. (shrink)

What makes a multimillion-dollar, transnational intimate industry possible when most people see it as exploitative? Using the newly emergent case of commercial surrogacy in India, this article extends the literature on stratified reproduction and intimate industries by examining how surrogacy persists and thrives despite its common portrayal as the “rent-a-womb industry” and “baby factory.” Using interview data with eight infertility specialists, 20 intended parents, and 70 Indian surrogate mothers, as well as blogs and media stories, we demonstrate how market actors (...) justify their pursuits through narrating moral frames of compassion and altruism that are not incidental but systematic to and constitutive of transnational surrogacy. We observed two predominant moral frames: surrogacy liberates and empowers Indian women from patriarchal control; and surrogacy furthers reproductive rights. Within these frames, the market exchange of money for babies is cast as compassion, which allows commissioning clients to sidestep accusations of racism, classism, and sexism. Yet, we reveal that the ability to navigate around these threats relies on racist, classist, and sexist tropes about Third World working-class women. Further, we find that surrogate mothers did not experience significant changes in economic status after surrogacy. (shrink)

The thesis advanced in this paper is that the proper names of cities or countries inherit the linguistic types of the nouns which denote the basic category of the objects the names refer to. As a result, in the case of the proper names of cities or countries, a reference by those names may select particular aspects of those objects, in the same way that book or newspaper selects the physical or informational aspects of objects in the extension of the (...) nouns. This view is based on Asher’s and Pustejovsky’s conception of dot type semantics. (shrink)

We show that truth conditions for counterfactuals need not always be given in terms of a vague notion of similarity. To this end, we single out the important class of historical counterfactuals and give formally rigorous truth conditions for these counterfactuals, employing a partial ordering relation called "comparative closeness" that is defined in the framework of branching space-times. Among other applications, we provide a detailed analysis of counterfactuals uttered in the context of lost bets. In an appendix we compare our (...) theory with the branching space-times based reading of counterfactuals recently proposed by Belnap. (shrink)

The paper describes two approaches to determinism: one focuses on the features of global objects, such as possible worlds or models of a theory, whereas the other’s concern is the possible behaviour of individual objects. It then gives an outline of an individuals-based analysis of the determinism of theories. Finally, a general relativistic spacetime with non-isometric extensions is described and used to illustrate a conflict between the two approaches: this spacetime is indeterministic by the first approach but deterministic by the (...) second approach.

The paper puts forward a theory of historical modalities that is framed in terms of possible continuations rather than possible worlds or histories. The proposal is tested as a semantic theory for a language with historical modalities, tenses, and indexicals.

Its interpretation, however, is as unsettled now as in the heroic days of Einstein and Bohr.This book focuses on quantum non-locality, the curious quantum ...

This collection celebrates the centenary of the Lvov-Warsaw school, established by Kazimierz Twardowski in Lvov in 1895.

The objectives of this paper are twofold. The first is to present a differentiation between two kinds of deferred uses of indexicals: those in which indexical utterances express singular propositions (I term them deferred reference proper) and those where they express general propositions (called descriptive uses of indexicals). The second objective is the analysis of the descriptive uses of indexicals. In contrast to Nunberg, who treats descriptive uses as a special case of deferred reference in which a property contributes to (...) the proposition expressed, I argue that examples in which a general proposition is indeed expressed by an indexical cannot be treated by assuming that the property is a deferred referent of the pronoun. I propose an analysis of descriptive uses of indexicals by means of a pragmatic mechanism of ‘descriptive anaphora’, which attempts to explain the special kind of contribution of the property retrieved from the context to the proposition that is characteristic of the descriptive interpretation.

In this article, we challenge Matushansky’s (Linguistics and Philosophy,21, 573–627, 2008) small clause treatment of proper names in naming constructions. While she is widely credited with establishing, based on cross-linguistic evidence, that names should be viewed as predicates in naming constructions, we present a counterexample from Polish that questions the universal interpretation of the small clause hypothesis (SCH). This leads us to advocate for an alternative analysis of proper names in naming constructions, wherein they are considered components of the argument (...) of a naming verb. We posit that this approach may have deflationist implications for predicativism concerning proper names, as it does not necessitate the existence of primitive name-predicates. We argue that there is no compelling positive evidence for the existence of predicative uses of names whose application conditions cannot be articulated using an equivalent phrase that quotes or mentions the name. Any apparent use of “Delia” as a predicate can be cast either (i) as not really a predicate, but rather an argument mentioning the name “Delia,” or (ii) as a genuine predicate, albeit one with an application condition defined by one of the well-established existing predicates, such as “individual called ‘Delia,’” where the name is mentioned. Predicative uses of names are thus dependent on the mention of names, and so there is a sense in which there are no primitive name-predicates. (shrink)

Proper names are typically considered to be devices of individual reference. Since Frege (1882), the debate has mainly concerned the proper semantic characteristics of this individual reference. Burge (J Philos 70:425–439, 1973) challenged this focus by highlighting the predicative uses of proper names and proposed that names are predicates even if they appear as bare singulars in the argument position. In turn, this unificatory account was subjected to criticism by Böer, Jeshion, and others, who provided counterexamples to the predicativist analysis (...) of proper names. In this paper, I want to analyze the nonreferential uses of proper names, which, by being nonreferential, provide a challenge for both predicativism and referentialism about proper names. I critically examine the processes proposed as possible accounts of the problematic examples, i.e. deferred reference, meaning transfer, and coercion, and argue that they do not provide an adequate analysis. I propose an interpretive mechanism that accounts for these problematic uses of proper names, as well as a new principle for classifying the kinds of uses of proper names based on the interpretive mechanisms underlying those uses and which includes all of the kinds of uses discussed in the literature.

Introduction to a special issue of Erkenntnis.

We investigate the concepts of past, present, and future that build upon a modal distinction between a settled past and an open future. The concepts are defined in terms of a pre-causal ordering that is determined by the qualitative differences between alternative possible histories. We look what an event’s past, present, and future look like in the so-called Minkowskian Branching Structures, one in which histories are isomorphic to Minkowski space-time.

What type of conceptual information about an object do we get at a brief glance? In two experiments, we investigated the nature of conceptual tokening—the moment at which conceptual information about an object is accessed. Using a masked picture-word congruency task with dichoptic presentations at “brief” (50−60 ms) and “long” (190−200 ms) durations, participants judged the relation between a picture (e.g., a banana) and a word representing one of four property types about the object: superordinate (fruit), basic level (banana), a (...) high-salient (yellow), or low-salient feature (peel). In Experiment 1, stimuli were presented in black-and-white; in Experiment 2, they were presented in red and blue, with participants wearing red-blue anaglyph glasses. This manipulation allowed for the independent projection of stimuli to the left- and right-hemisphere visual areas, aiming to probe the early effects of these projections in conceptual tokening. Results showed that superordinate and basic-level properties elicited faster and more accurate responses than high- and low-salient features at both presentation times. This advantage persisted even when the objects were divided into categories (e.g., animals, vegetables, vehicles, tools), and when objects contained high-salient visual features. However, contrasts between categories show that animals, fruits, and vegetables tend to be categorized at the superordinate level, while vehicles tend to be categorized at the basic level. Also, for a restricted class of objects, high-salient features representing diagnostic color information (yellow for the picture of a banana) facilitated congruency judgments to the same extent as that of superordinate and basic-level labels. We suggest that early access to object concepts yields superordinate and basic-level information, with features only yielding effects at a later stage of processing, unless they represent diagnostic color information. We discuss these results advancing a unified theory of conceptual representation, integrating key postulates of atomism and feature-based theories. (shrink)

Against the background of the theory of branching space-times (BST), the paper sketches a concept of individuals. It discusses Kripkean modal intuitions concerning individuation, and, finally it addresses Lewis’s objections to branching individuals.

Reichenbach’s Common Cause Principle is the claim that if two events are correlated, then either there is a causal connection between the correlated events that is responsible for the correlation or there is a third event, a so called (Reichenbachian) common cause, which brings about the correlation. The paper reviews some results concerning Reichenbach’s notion of common cause, results that are directly relevant to the problem of how one can falsify Reichenbach’s Common Cause Principle. Special emphasis will be put on (...) the question of whether EPR-type correlations can have an explanation in terms of Reichenbachian common causes. Most of the results to be recalled indicate that falsifying Reichenbach’s Common Cause Principle is much more tricky than one may have thought and that, contrary to some claims in the literature, there is no conclusive proof yet that the EPR correlations predicted by ordinary, non-relativistic quantum mechanics cannot have a common cause; furthermore, recent results about possible Reichenbachian common causes of correlations predicted by quantum field states between spacelike separated local observable algebras in algebraic quantum field theory strongly indicate that there may very well exist Reichenbachian common causes of superluminal correlations predicted by quantum field theory.

One diagnosis of Bell's theorem is that its premise of Outcome Independence is unreasonably strong, as it postulates one common screener system that purports to explain all the correlations involved. This poses a challenge of constructing a model for quantum correlations that is local, non-conspiratorial, and has many separate screener systems rather than one common screener system. In particular, the assumptions of such models should not entail Bell's inequalities. We prove that the models described do not exist, and hence, the (...) diagnosis above is incorrect. (shrink)

A small probability space representation of quantum mechanical probabilities is defined as a collection of Kolmogorovian probability spaces, each of which is associated with a context of a maximal set of compatible measurements, that portrays quantum probabilities as Kolmogorovian probabilities of classical events. Bell's theorem is stated and analyzed in terms of the small probability space formalism.

The paper develops a theory of branching spatiotemporal histories that accommodates indeterminism and the insights of general relativity. A model of this theory can be viewed as a collection of overlapping histories, where histories are defined as maximal consistent subsets of the model's base set. Subsequently, generalized manifolds are constructed on the theory's models, and the manifold topology is introduced. The set of histories in a model turns out to be identical with the set of maximal subsets of the model's (...) base set with respect to being Hausdorff and downward closed. Further postulates ensure that the topology is connected, locally Euclidean, and satisfies the countable sub-cover condition. (shrink)

Paul Horwich is aware of the fact that his theory as stated in his works is directly applicable only to a language in which a word, understood as a syntactic type, is connected with exactly one literal meaning. Yet he claims that the theory is expandable to include homonymy and indexicality and thus may be considered as applicable to natural language. My concern in this paper is with yet another kind of ambiguity—systematic polysemy—that assigns multiple meanings to one linguistic type. (...) I want to combine the characteristics of systematic polysemy with the Kaplanian insight that meanings of expressions may be defined by semantic rules which assign content in context and to ask the question if minimalism about truth and meaning is compatible with such rule-based systematic polysemy. I will first explain why the expressions that exhibit rule-based systematic polysemy are difficult to combine with a truth theory that is based on a use theory of meaning before proceeding to argue that indexicals and proper names are such expressions. (shrink)

Proper names are usually considered devices of singular reference but, when considered as word-types, they also exhibit other kinds of uses. In this paper I intend to show that systematic kinds of uses of proper names considered as word-types can be accounted for by a generalized rule-based conception of systematic polysemy, one which not only postulates a multiplicity of stable senses for an expression, but also a multiplicity of content generating rules, each of which determines potentially different contents in different (...) contexts. In contrast to the currently extant polysemous conceptions of proper names (Leckie in Philos Stud 165:1139–1160, 2013), which only encompass individual and predicative uses, the presented proposal concerns all systematic uses of proper names considered in the literature, i.e., individual, predicative, deferred, descriptive, anaphoric, and bound uses of proper names. The resulting conception accommodates referential intuition about the default individual uses of proper names while also admitting other kinds of uses without generating homonymy. It transpires that proper names are semantically underdetermined and context-sensitive expressions. (shrink)

Health science students frequently experience ethical dilemmas on clinical placements, yet ethics education rarely prepares students with the ethical leadership skills required. The Leadership in Ethical Practice (LEP) program is an ethics education resource designed to enhance health science students’ knowledge and skills in ethical leadership to prepare them for clinical placements and future professional practice. This qualitative study aimed: to explore the nature of students’ ethical leadership goals; determine whether a specific, measurable, achievable, relevant, and time-bound (SMART) format was (...) an effective tool for students to create ethical leadership goals; and identify any changes in students’ pre- and post-self-ratings of ethical leadership knowledge following the LEP program. Eighty-two diagnostic radiography students from the University of Sydney participated in the study. Inductive and deductive qualitative content analysis (Elo & Kyngas, 2008) were used to explore students’ goals. Descriptive statistics were used to investigate students’ pre- and post-self-ratings. Four themes emerged from students’ goals: initiative, competence, and courage in ethical reasoning; communicating ethical stories through listening, questioning, and connecting; reflecting and growing as an ethical leader; and safe practice and person-centred outcomes. SMART goal format elements were evident in 61% of students’ goals. Students' ethical leadership self-ratings showed positive changes after participating in the LEP program. Findings indicated students planned to further develop ethical leadership skills during clinical placements and future professional practice. This study demonstrated the ethics education approaches used within the LEP could assist health science students to apply ethical leadership in future clinical practice. (shrink)

The paper defends an Aristotelian notion of indeterminism, as rigorously formulated in the framework of branching space-times (BST) of Belnap (1992), against the model-theoretic characterization of indeterminism that Montague (1962) introduced into the philosophy of science. It delineates BST branching against the background provided by Earman's (2008) distinction between individual vs. ensemble branching. It describes a construction of physically-motivated BST models, in which histories are isomorphic to Minkowski spacetime. Finally it responds to criticism leveled against BST by addressing some semantical (...) questions, a topological issue, and the past/future asymmetry. (shrink)

Since the validity of Bell's inequalities implies the existence of joint probabilities for non-commuting observables, there is no universal consensus as to what the violation of these inequalities signifies. While the majority view is that the violation teaches us an important lesson about the possibility of explanations, if not about metaphysical issues, there is also a minimalist position claiming that the violation is to be expected from simple facts about probability theory. This minimalist position is backed by theorems due to (...) A. Fine and I. Pitowsky.Our paper shows that the minimalist position cannot be sustained. To this end,we give a formally rigorous interpretation of joint probabilities in thecombined modal and spatiotemporal framework of `stochastic outcomes inbranching space-time' (SOBST) (Kowalski and Placek, 1999; Placek, 2000). We show in this framework that the claim that there can be no joint probabilities fornon-commuting observables is incorrect. The lesson from Fine's theorem is notthat Bell's inequalities will be violated anyhow, but that an adequate modelfor the Bell/Aspect experiment must not define global joint probabilities. Thus we investigate the class of stochastic hidden variable models, whichprima facie do not define such joint probabilities. The reasonwhy these models fail supports the majority view: Bell's inequalities are notjust a mathematical artifact. (shrink)

The objective of the paper is to present a comprehensive picture of Bell-type theorems, by giving both the theorems and the proofs of them.Special care is given to specifying the assumptions of the arguments and their physical or metaphysical significance. Taking the EPR argument as a point of departure, the paper discusses four probabilitic Bell-type theorems,which are then followed by two versions on non-probailitic (GHZ) arguments.The final section provides the reader with a classification of the assumptions, which specifies which assumption (...) is used in which proof.

The aim of this paper is to reconstruct Brouwer’s justification for the intuitionistic revision of logic and mathematics. It is attempted to show that pivotal premisses of his argument are supplied by his philosophy. To this end, the basic tenets of his philosophical doctrine are discussed: the concepts of mind, causal attention, intuition of two-ity and his repudiation of realism.The restriction of intuitionistically allowable objects to spreads and species is traced back to Brouwer’s concept of intuition that is a defining (...) feature of his notion of mind. On the other hand, it is argued that his objections to some laws of classical logic result from the rejection of the rule of double negation elimination, which in turn follows from both, the claim that rules of logic should preserve evidence for assertions rather than truth, and too restrictive a concept of evidence.
