Alasdair Richmond introduces some famous paradoxes about time travel.

The negative impact of adverse experiences in childhood on neurodevelopment is well documented. Less attention however has been given to the impact of variations in “normative” parenting behaviors. The influence of these parenting behaviors is likely to be marked during periods of rapid brain reorganization, such as late childhood. The aim of the current study was to investigate associations between normative parenting behaviors and the development of structural brain networks across late childhood. Data were collected from a longitudinal sample of (...) 114 mother-child dyads (54% female children,Mage 8.41 years, SD = 0.32 years), recruited from low socioeconomic areas of Melbourne, Australia. At the first assessment parenting behaviors were coded from two lab-based interaction tasks and structural magnetic resonance imaging (MRI) scans of the children were performed. At the second assessment, approximately 18 months later (Mage 9.97 years, SD = 0.37 years) MRI scans were repeated. Cortical thickness (CT) was extracted from T1-weighted images using FreeSurfer. Structural covariance (SC) networks were constructed from partial correlations of CT estimates between brain regions and estimates of network efficiency and modularity were obtained for each time point. The change in these network measures, from Time 1 to Time 2, was also calculated. At Time 2, less positive maternal affective behavior was associated with higher modularity (more segregated networks), while negative maternal affective behavior was not related. No support was found for an association between local or global efficacy and maternal affective behaviors at Time 2. Similarly, no support was demonstrated for associations between maternal affective behaviors and change in network efficiency and modularity, from Time 1 to Time 2. These results indicate that normative variations in parenting may influence the development of structural brain networks in late childhood and extend current knowledge about environmental influences on structural connectivity in a developmental context.

At a certain stage of advance in any science it may be well to re-examine and perhaps to rearrange its fundamentals. One seeks an ideal, logical order of development, which may or may not be the best pedagogical order. Many a high school beginner in physics has become acquainted with “force” as something that gets in between two bodies of matter and pulls them together or pushes them apart, like himself between two carts or like “magnetism” between two magnets. Whether (...) or not this might ever be a proper view, the mature student of today will consider that for him, a knowledge of accelerations and strains, inter alia, is prerequisite to a knowledge of force.

Meges, ruler of the men of Dulichium and the Echinades, is a personage who has occasioned some trouble to the commentators on the Iliad. The difficulties are stated fully, perhaps over-fully, by Walter Leaf.

Utilitarians take an uncritical attitude toward the sort of individual claims they seek to aggregate. In this way they cannot account for an individual's valid claim against a policy which actually maximizes aggregate satisfaction. We thus claim that utilitarianism properly functions only after conflicting claims have been adjudicated; consequently, Utilitarianism properly maximizes the satisfaction of claims judged to be valid. In such a program, Utilitarianism ceases to be considered a part of ethics, But is seen as maintaining a principle of (...) feasibility and efficiency. Finally, We briefly suggest the methods we believe to be most effective in the resolution of ethical conflict. (shrink)

Vollmer, modifying the transposition by Fr. Jacobs of 61–74 after 24, placed these lines after 23; this finally put paid to the reading exordiar astus, which the authority of the Aldine edition had imposed on the early editors, and consequently v. 24 could no longer be taken as concluding the sense of the preceding lines.

Nelson Goodman has constructed two theories of simplicity: one of predicates; one of hypotheses. I offer a simpler theory by generalization and abstraction from his. Generalization comes by dropping special conditions Goodman imposes on which unexcluded extensions count as complicating and which excluded extensions count as simplifying. Abstraction is achieved by counting only nonisomorphic models and subinterpretations. The new theory takes into account all the hypotheses of a theory in assessing its complexity, whether they were projected prior to, or result (...) from, projection of a given hypothesis. It assigns simplicity post-projection priority over simplicity pre-projection. It better orders compound conditionals than does the theory of simplicity of hypotheses, and it does not inherit an anomaly of the theory of simplicity of predicates — its failure to order the ordering relations. Drop Goodman's special conditions, and the problems fall away with them. (shrink)

Modern epistemology has run into several paradoxes in its efforts to explain how knowledge acquisition can be both socially based and still able to determine objective facts about the world. In this important book, Richmond Campbell attempts to dispel some of these paradoxes, to show how they are ultimately just "illusions of paradox," by developing ideas central to two of the most promising currents in epistemology: feminist epistemology and naturalized epistemology. Campbell's aim is to construct a coherent theory of (...) knowing that is feminist and "naturalized." Illusions of Paradox will be valuable for students and scholars of epistemology and women's studies. (shrink)

A medical information commons is a networked data environment utilized for research and clinical applications. At three deliberations across the U.S., we engaged 75 adults in two-day facilitated discussions on the ethical and social issues inherent to sharing data with an MIC. Deliberants made recommendations regarding opt-in consent, transparent data policies, public representation on MIC governing boards, and strict data security and privacy protection. Community engagement is critical to earning the public's trust.

My chief aim has been to convey the thought that the application of model theoretic techniques to natural languages needn't force a distortion of intentional phenomena. I hope that at least I have succeeded in accomplishing this.

Early attempts at combining multiple inheritance with nonmonotonic reasoning were based on straightforward extensions of tree-structured inheritance systems, and were theoretically unsound. In The Mathcmat~'cs of Inheritance Systcrns, or TMOIS, Touretzky described two problems these systems cannot handle: reasoning in the presence of true but redundant assertions, and coping with ambiguity. TMOIS provided a definition and analysis of a theoretically sound multiple inheritance system, accom-.

Antiphon, in his fifth oration, relates that c. 422–413 B.C. Euxitheos, a young Mytilenean, and Herodes, probably an Athenian cleruch in Mytilene, embarked together on a ship bound from Mytilene for Ainos in Thrace. Shortly after they left port, a storm forced them to put into an unnamed harbour in Methymnian territory. The two men left their uncovered ship to take shelter in a covered one; whether others from their own ship went with them is not indicated. During the night, (...) a drinking party ensued. Herodes, after heavy drinking, left the covered ship and disappeared; he could not be found in the morning, nor even after two days of searching. When the weather cleared, the search was abandoned, and all ships in the port resumed their voyages. On Euxitheos' return to Mytilene, a charge of murder was brought against him by Herodes' relatives, who tried him in Athens. Antiphon's fifth oration is his final defence; we do not know whether the speech was successful. (shrink)

We relate the theory of presupposition accommodation to a computational framework for reasoning in conversation. We understand presuppositions as private commitments the speaker makes in using an utterance but expects the listener to recognize based on mutual information. On this understanding, the conversation can move forward not just through the positive effects of interlocutors’ utterances but also from the retrospective insight interlocutors gain about one anothers’ mental states from observing what they do. Our title, ENLIGHTENED UPDATE, highlights such cases. Our (...) approach fleshes out two key principles: that interpretation is a form of intention recognition; and that intentions are complex informational structures, which specify commitments to conditions and to outcomes as well as to actions. We present a formalization and implementation of these principles for a simple conversational agent, and draw on this case study to argue that pragmatic reasoning is holistic in character, continuous with common-sense reasoning about collaborative activities, and most effectively characterized by associating specific, reliable interpretive constraints directly with grammatical forms. In showing how to make such claims precise and to develop theories that respect them, we illustrate the general place of computation in the cognitive science of language. (shrink)
