The article attempts to settle a controversy between d f pears and j o urmson over the nature of russell's early theory of memory. it is shown that contrary to what pears claims in his "bertrand russell and the british tradition in philosophy," russell had explicitly abandoned a realist account of memory by 1915. the article sides with urmson as against pears, but apparently both have overlooked two of russell's little noticed 1915 papers in the "monist.".

J. o. urmson's contention that russell held that 'to show that 'x' is an incomplete symbol is tantamount to showing that there are no x's' is shown to rest partly upon a misreading of "principia", pp. 71-72, where russell reveals what he means by a 'definite proof' that a symbol is incomplete, and partly upon a misunderstanding of russell's use of the expression 'logical fiction'.

OTAWEINBERGER Universitiit Graz RUSSELL'S REALIST THEORY OF REMOTE MEMORY In a paper on Bertrand Russell's theory of memory1 David Pears undertakes to amend certain aspects of his version of Russell's theory of memory which he had presented in his Bertrand Russell and the British Tradition in Philosophy. ~ In that work Pears had attributed to Russell an extreme realist theory of memory from 1905 through 1918, i.e., a general theory of memory according to which the mind maintains direct contact by the dual relation of acquaintance with past sense-data. 3 This, he now believes, is historically incorrect in view of two of Russell's lesser known papers which have since come to his attention and which make it clear that in 1915 Russell held the extreme realist account only in connection with immediate memory--i.e., with memory within what is often called the specious present--and that as regards remote memory--i.e., memory of things not very recent and, so, outside the specious present--past sense-data 7 Poincare, Letzte Gedanken, aus dem FranzSsischen iibersetzt yon Karl Lichteneeker (Leipzig : Akademische Verlagsgesellschaft, 1913),pp. 226 f. 1 D.

NOTES AND DISCUSSIONS 359 were knowable only by description and not by acquaintance.4 But Pears still argues, as against J. O. Urmson,5 that Russell did hold the realist theory of remote memory before 1915, although he was "changing his mind" in that year and, by 1917 ("The Philosophy of Logical Atomism"), had definitely abandoned the theory,e I believe that Pears is partly right about this matter: Russell almost certainly did hold a realist theory of remote memory before 1915. However, it can be shown, I think, that the theory was abandoned, not in 1915 or later, but in 1914. Pears shows beyond any reasonable doubt that Russell held a realist theory of remote memory in 1912. The strongest evidence may be found in a passage in Problems of Philosophy: There is some danger of confusion as to the nature of memory, owing to the fact that memory of an object is apt to be accompanied by an image of the object, and yet the image cannot be what constitutes memory. This is easily seen by merely noticing that the image is in the present, whereas what is remembered is known to be in the past. Moreover, we are certainly able to some extent to compare our image with the object remembered, so that we often know, within... (shrink)

Urmson is correct in holding that russell's use of "logical fiction" does usually involve ontological implications. But the issue is more complex than he seems to realize. Because russell's program of logical construction is revisionary, The question "are there really x's?" is ambiguous and can be taken as asking either: (a) are there x's as thought of pre-Analytically? or (b) are there x's as thought of post-Analytically? russell gives different answers in each case.

Apoptosis is now widely recognized as a common form of cell death and represents a mechanism of cell clearance in many physiological situations where deletion of cells is required. Peptide growth factors, initially characterised as stimulators of cell proliferation, have now been shown to inhibit death in many cell types. Deprivation of growth factors leads to the induction of apoptosis, i.e. condensation of chromatin and degradation in oligonucleosomesized fragments, formation of plasma and nuclear membrane blebs and cell fragmentation into apoptotic (...) bodies which can be taken up by neighbouring cells. Here we discuss the mechanism(;s) by which growth factors may inhibit apoptosis. (shrink)

Chicago and La Salle, Ill.: Open Court, . Pp. xii, . .; pb .. lthough Bertrand Russell was obviously a prolific writer on numerous Atopics (technical philosophy, education, religion, (...) political critique, women ’s rights, and nuclear disarmament), and published his views through various venues such as technical volumes, popular books, essays, scholarly articles, reviews, and pamphlets, there has been a neglect of Russell’s utilization of the newspaper’s “Letters to the Editor” section. In this accessible volume, Ray Perkins has collected and organized the letters to the editor published by Russell. Russell, from the first known letter in  to the final public statement on the Middle East crisis published posthumously in , published approximately  letters to the editor. Of these  are published in Yours Faithfully. Perkins begins with a helpful introduction (pp. –), placing the letters into the broader framework of Russell’s life. We are introduced, in a very basic sketch, to the development of Russell’s thought, encountering such major threads in Russell’s life as his early political interests (indicated in  with German Social Democracy, though pushed to the foreground with the First World War) and the developments in his philosophical theories from Principia Mathematica through Our Knowledge of the External World to Human Knowledge. We also meet various significant individuals in Russell’s life, such as his various wives and his colleagues both in philosophy and in activist work. Although Russell scholars will find this introduction somewhat simplistic, those non-specialists encountering Russell through this book will find the introduction helpful and clearly necessary in order to contextualize the letters.  Reviews The letters themselves are organized into chronological chapters. The first eight letters, “Early Letters”, are dated from  to . These are the earliest known published letters by Russell. Perkins then gives us those letters published during the First World War (–). The remaining letters fall into: “Between the Wars” (–); “World War Two and the Early Cold War” (–); “The Cold War and the Nuclear Peril” (–); and “The Cold War and American Militarism” (–). The final document is Russell’s posthumous  statement to the Conference of Parliamentarians in Cairo. Each chapter has a brief overview of the period in Russell’s life, further situating the letters. Perkins is also careful to offer introductions to each letter, and the occasional footnote to explain various references in the letters (names of individuals that may not be familiar to readers, major events referred to, etc.). Each letter is numbered sequentially, accompanied by the B&R number of the letter. Given Russell’s diverse interests, clearly reflected in these letters, Perkins has subdivided the last four chapters into thematic subsections. Those readers who are interested in Russell’s views on, e.g., religion, education, or Vietnam can find the relevant letters with ease. A comprehensive index also makes the collection accessible. The exact division of the chapters tends to reflect major shifts in Russell’s thinking as much as historical developments (the latter obviously affecting the former in any case). For example, the – break reflects both Russell’s move from England to the  and his departure from the pacifist stance of Which Way to Peace? The – break reflects Russia’s development of nuclear weapons and Russell’s shift towards mutual disarmament by both superpowers. And the – break reflects Russell’s intervention in the Cuban Missile Crisis as well as his reactions to the  involvement in Vietnam. Perkins has supplied us with an excellent collection of letters. Although some may ask how useful such a collection may be, I would contend that the letters are vital sources of information for Russell studies. First, from an historian’s perspective, the preservation and accessibility of primary material is a noble and worthwhile achievement. Perkins is to be commended for his efforts in drawing our attention to this material by blowing the dust off material that most would ignore. Second, the letters themselves are fascinating indications of shifts in Russell’s thinking, pointing out the nuances of such shifts as he engages in debate with various other voices over... (shrink)

The US neutrino community gathered at the Workshop on the Intermediate Neutrino Program at Brookhaven National Laboratory February 4-6, 2015 to explore opportunities in neutrino physics over the next five to ten years. Scientists from particle, astroparticle and nuclear physics participated in the workshop. The workshop examined promising opportunities for neutrino physics in the intermediate term, including possible new small to mid-scale experiments, US contributions to large experiments, upgrades to existing experiments, R&D plans and theory. The workshop was organized into (...) two sets of parallel working group sessions, divided by physics topics and technology. Physics working groups covered topics on Sterile Neutrinos, Neutrino Mixing, Neutrino Interactions, Neutrino Properties and Astrophysical Neutrinos. Technology sessions were organized into Theory, Short-Baseline Accelerator Neutrinos, Reactor Neutrinos, Detector R&D and Source, Cyclotron and Meson Decay at Rest sessions.This report summarizes discussion and conclusions from the workshop.

BACKGROUND: Serotonin transporter promoter genotype appears to increase risk for depression in the context of stressful life events. However, the effects of this genotype on measures of stress sensitivity are poorly understood. Therefore, this study examined whether 5-HTTLPR genotype was associated with negative information processing biases in early childhood. METHOD: Thirty-nine unselected seven-year-old children completed a negative mood induction procedure and a Self-Referent Encoding Task designed to measure positive and negative schematic processing. Children were also genotyped for the 5-HTTLPR gene. (...) RESULTS: Children who were homozygous for the short allele of the 5-HTTLPR gene showed greater negative schematic processing following a negative mood prime than those with other genotypes. 5-HTTLPR genotype was not significantly associated with positive schematic processing. LIMITATIONS: The sample size for this study was small. We did not analyze more recently reported variants of the 5-HTTLPR long alleles. CONCLUSIONS: 5-HTTLPR genotype is associated with negative information processing styles following a negative mood prime in a non-clinical sample of young children. Such cognitive styles are thought to be activated in response to stressful life events, leading to depressive symptoms; thus, cognitive styles may index the "stress-sensitivity" conferred by this genotype.

OBJECTIVES: Early-emerging, temperamental differences in fear-related traits may be a heritable vulnerability factor for anxiety disorders. Previous research indicates that the serotonin transporter promoter region polymorphism is a candidate gene for such traits. METHODS: Associations between 5-HTTLPR genotype and indices of fearful child temperament, derived from maternal report and standardized laboratory observations, were examined in a community sample of 95 preschool-aged children. RESULTS: Children with one or more long alleles of the 5-HTTLPR gene were rated as significantly more nervous during (...) standardized laboratory tasks than children who were homozygous for the short alleles. Children homozygous for the short alleles were also rated as significantly shyer, by maternal report, than those with at least one copy of the long allele of the 5-HTTLPR gene. CONCLUSIONS: This study extends the literature linking the short alleles of the serotonin transporter promoter region polymorphism to fear and anxiety-related traits in early childhood and adulthood, and is one of very few studies to examine the molecular genetics of preschoolers' temperament using multiple measures of traits in a normative sample.

© 2015 Elsevier Inc.Postnatal organogenesis occurs in an immune competent environment and is tightly controlled by interplay between positive and negative regulators. Innate immune cells have beneficial roles in postnatal tissue remodeling, but roles for the adaptive immune system are currently unexplored. Here we show that adaptive immune responses participate in the normal postnatal development of a non-lymphoid epithelial tissue. Since the mammary gland is the only organ developing predominantly after birth, we utilized it as a powerful system to study (...) adaptive immune regulation of organogenesis. We found that antigen-mediated interactions between mammary antigen-presenting cells and interferon-γ -producing CD4+ T helper 1 cells participate in MG postnatal organogenesis as negative regulators, locally orchestrating epithelial rearrangement. IFNγ then affects luminal lineage differentiation. This function of adaptive immune responses, regulating normal development, changes the paradigm for studying players of postnatal organogenesis and provides insights into immune surveillance and cancer transformation.

This is the first book to offer the best essays, articles, and speeches on ethics and intelligence that demonstrate the complex moral dilemmas in intelligence collection, analysis, and operations. Some are recently declassified and never before published, and all are written by authors whose backgrounds are as varied as their insights, including Robert M. Gates, former Director of the Central Intelligence Agency; John P. Langan, the Joseph Cardinal Bernardin Professor of Catholic Social Thought at the Kennedy Institute of Ethics, Georgetown (...) University; and Loch K. Johnson, Regents Professor of Political Science at the University of Georgia and recipient of the Owens Award for contributions to the understanding of U.S. intelligence activities. Creating the foundation for the study of ethics and intelligence by filling in the gap between warfare and philosophy, this is a valuable collection of literature for building an ethical code that is not dependent on any specific agency, department, or country.

Papers collected in this volume were originally presented at a symposium held at the University of Pennsylvania in December, 1968 and revised in the light of discussion at the symposium for publication. The contributors hold different views about the role played by induction in theories of knowledge and rational belief but many of the papers are conciliatory, reflecting no doubt a good deal of helpful communication at the symposium. For example, Frederic Schick's clearly written and informative lead article considers subjectivist, (...) empiricist, and pragmatist theories of rational belief, arguing that they are compatible theories relevant to different types of issues. Marshall Swain follows with an article which presents a general framework within which rules of rational acceptance can be constructed. An exchange between Isaac Levi and Richard Jeffrey shows that advocates of theories of acceptance and theories of partial belief may be defending complementary and not mutually exclusive theories. In the remaining three essays Henry Kyburg Jr., Gilbert Harman, and Keith Lehrer defend their own distinctive views about the nature of inductive inference and rational belief. Kyburg traces difficulties in some theories to the acceptance of the principle of conjunction which he rejects. Harman and Lehrer both see the relation of inductive inference to explanation as crucial to understanding the former and they develop theories along different lines which make use of this relation. A long and useful bibliography was prepared for the symposium by Ralph L. Slaght and revised for publication in the volume.--R. H. K. (shrink)
