A two-body quantum correlation is calculated for a particle reflecting from a moving mirror. Correlated interference results when the incident and reflected particle substates and their associated mirror substates overlap. Using the Copenhagen interpretation of measurement, an asynchronous joint probability density, which is a function both of the different positions and different times at which the particle and mirror are measured, is derived assuming that no interaction occurs between each measurement. Measurement of the particle first, in the correlated interference region, (...) results in a splitting of the mirror substate into ones which have and have not reflected the particle. An analog of the interference from the Doppler effect for only measurements of the particle, in this two-body system, is shown to be a consequence of the asynchronous measurement. The simplification obtained for a microscopic particle reflecting from a mesoscopic or macroscopic mirror is used to illustrate asynchronous correlation interferometry. In this case, the small displacement between these mirror states can yield negligible environmental decoherence times. In addition, interference of these mirror states does not vanish in the limit of large mirror mass due to the small momentum exchange in reflecting a microscopic particle. (shrink)

The notorious ‘measurement problem’ has been roving around quantum mechanics for nearly a century since its inception, and has given rise to a variety of ‘interpretations’ of quantum mechanics, which are meant to evade it. We argue that no less than six problems need to be distinguished, and that several of them classify as different types of problems. One of them is what traditionally is called ‘the measurement problem’. Another of them has nothing to do with measurements but is a (...) profound metaphysical problem. We also analyse critically Maudlin’s (Topoi 14:7–15, 1995) well-known statement of ‘three measurements problems’, and the clash of the views of Brown (Found Phys 16:857–870, 1986) and Stein (Maximal of an impossibility theorem concerning quantum measurement. In: R. S. Cohen et al. (Eds.), Potentiality, entanglement and passion-at-a-distance, 1997) on one of the six measurement problems. Finally, we summarise a solution to one measurement problem which has been largely ignored but tacitly if not explicitly acknowledged. (shrink)

Evolutionary developmental biology (evo-devo) has undergone dramatic transformations since its emergence as a distinct discipline. This paper aims to highlight the scope, power, and future promise of evo-devo to transform and unify diverse aspects of biology. We articulate key questions at the core of eleven biological disciplines—from Evolution, Development, Paleontology, and Neurobiology to Cellular and Molecular Biology, Quantitative Genetics, Human Diseases, Ecology, Agriculture and Science Education, and lastly, Evolutionary Developmental Biology itself—and discuss why evo-devo is uniquely situated to substantially improve (...) our ability to find meaningful answers to these fundamental questions. We posit that the tools, concepts, and ways of thinking developed by evo-devo have profound potential to advance, integrate, and unify biological sciences as well as inform policy decisions and illuminate science education. We look to the next generation of evolutionary developmental biologists to help shape this process as we confront the scientific challenges of the 21st century. (shrink)

Background: Growing evidence suggests that collaborative practice improves healthcare outcomes, but the precursors to collaborative behavior between nurses and physicians have not been fully explored. Research question: The purpose of this descriptive correlational study was to describe the professional values held by nurses and their attitudes toward physician–nurse collaboration and to explore the relationships between nurses’ characteristics (e.g. education, type of work) and professional values and their attitudes toward nurse–physician collaboration. Research design: This descriptive correlational study examines the relationship between (...) nurses’ professional values (Nurses Professional Values Scale–Revised) and their attitudes toward nurse–physician collaboration (Jefferson Scale of Attitudes toward Physician–Nurse Collaboration). Ethical considerations: Permission to conduct the study was received from the hospital, and the Institutional Review Boards of the healthcare system and the participating university. Participants/context: A convenience sample of 231 registered nurses from a tertiary hospital in the United States was surveyed. Findings: A significant positive relationship was found between nurses’ professional values and better attitudes toward collaboration with physicians ( r =.26, p <.01). Attitude toward collaboration with physicians was also positively associated with master’s or higher levels of education ( F(3, 224) = 4.379, p =.005). Discussion: The results of this study can be helpful to nurse administrators who are responsible for developing highly collaborative healthcare teams and for nurse educators who are focused on developing professional values in future nurses.

We report the identification of a recurrent, 520-kb 16p12.1 microdeletion associated with childhood developmental delay. The microdeletion was detected in 20 of 11,873 cases compared with 2 of 8,540 controls and replicated in a second series of 22 of 9,254 cases compared with 6 of 6,299 controls. Most deletions were inherited, with carrier parents likely to manifest neuropsychiatric phenotypes compared to non-carrier parents. Probands were more likely to carry an additional large copy-number variant when compared to matched controls. The clinical (...) features of individuals with two mutations were distinct from and/or more severe than those of individuals carrying only the co-occurring mutation. Our data support a two-hit model in which the 16p12.1 microdeletion both predisposes to neuropsychiatric phenotypes as a single event and exacerbates neurodevelopmental phenotypes in association with other large deletions or duplications. Analysis of other microdeletions with variable expressivity indicates that this two-hit model might be more generally applicable to neuropsychiatric disease. © 2010 Nature America, Inc.

In accordance with ethical principles and standards, researchers conducting studies with children are expected to seek assent and respect their dissent from participation. Little attention has been given to assent and dissent in research with toddlers, who have limited cognitive and emotional capabilities. We discuss research with toddlers in the context of assent and dissent and propose guidelines to ensure that research with toddlers still adheres to ethical principles. These guidelines include designing engaging studies, monitoring refusal and distress, and partnering (...) with parents. Research with toddlers requires flexibility and creativity to respect toddlers in the context of their developmental capabilities. (shrink)

The negative emotions generated following stressful life events can increase one’s risk of depressive symptoms and promote higher levels of perceived stress. The process model of emotion regulation can help distinguish between adaptive and maladaptive emotion regulation strategies to determine who may be at the greatest risk of worse psychological health across the lifespan. Heart rate variability may affect these relationships as it indexes aspects of self-regulation, including emotion and behavioral regulation, that enable an individual to dynamically adapt to the (...) changing demands of both internal and external environments. In this study, we expected individual differences in resting vagally mediated HRV to moderate the influence of emotion regulatory strategies among our sample of 267 adults. We found support for the hypothesis that higher vagally mediated HRV buffers against the typical adverse effects of expressive suppression when evaluating depressive symptoms and found weak support when considering perceived stress. There was no evidence for an interaction between cognitive reappraisal and vagally mediated HRV but there was a significant, negative association between cognitive reappraisal and depressive symptoms and perceived stress. Future work may determine if intervening on either emotion regulation strategies or HRV may change these within-persons over time. (shrink)

Modern developments in philosophy have provided us with tools, logical and methodological, that were not available to Medieval thinkers - a development that has its dangers as well as opportunities. Modern tools allow one to penetrate old texts and analyze old problems in new ways, offering interpretations that the old thinkers could not have known. But unless one remains sensitive to the fact that language has undergone changes, bringing with it a shift in the meaning of terminology, one can easily (...) perpetrate an anachronism. Yet there is a growing need to bring modern tools and to bear on the struggle for greater understanding of the problems studied and the solutions found by the ancient scholars. If we remain sensitive to the dangers, this openness to new methods can be expected to widen our perspectives and deepen our knowledge of old material. The focus in the present volume is on problems in Medieval and contemporary philosophy of religion. (shrink)

Burning fossil fuel in the North American continent contributes more to the CO2 global warming problem than in any other continent. The resulting climate changes are expected to alter food production. The overall changes in temperature, moisture, carbon dioxide, insect pests, plant pathogens, and weeds associated with global warming are projected to reduce food production in North America. However, in Africa, the projected slight rise in rainfall is encouraging, especially since Africa already suffers from severe shortages of rainfall. For all (...) regions, a reduction in fossil fuel burning is vital. Adoption of sound ecological resource management, especially soil and water conservation and the prevention of deforestation, is important. Together, these steps will benefit agriculture, the environment, farmers, and society as a whole. (shrink)

The title of this Festschrift to Stephen Brown points to the understanding of medieval philosophy and theology in the longue durée of their traditions and discourses.

Two decades of research using repeated false statements and underhanded information have shown that people can easily be made to believe that they have seen or experienced something they never did. In this paper, we discuss the possibility that the mental health professional and client may unknowingly collaborate to create a client′s false memory of childhood sexual abuse. Both therapist and client bring beliefs into therapy, and the confirmation bias shows that people discover what they already believe to be true. (...) What do people believe about memory? We asked 115 students for their reactions to various statements about how memory works; results showed widespread belief in the repression mechanism. A principal components analysis revealed that three larger beliefs explained 61% of the variance in the more specific beliefs: possible sources of memory distortions, memory for traumatic events, and the potential recoverability of memories. Finally, we discuss the ambiguity inherent in the term repression, as well as the generalizability of misinformation research to the repressed and recovered memories. (shrink)

Examining the influence of ancient Greek philosophy, as well as of the Arabian and Hebrew scholars who transmitted it, The A to Z of Medieval Philosophy and Theology presents the philosophy of the Christian West from the 9th to the early 17th century. This is accomplished through a chronology, an introduction, appendixes, a bibliography, and hundreds of cross-referenced dictionary entries on the philosophers, concepts, issues, institutions, and events, making this an important reference for the study of the progression of human (...) thought.

Hegel's interpretation of the history of philosophy played a central role in the shaping of his own thought, and brought about one of the determining events of modern intellectual history: the rise of a new historical consciousness of human life, culture, and intellect. This third volume of the lectures covers the medieval and modern periods.

Theories of consciousness have a long and controversial history. One well-known proposal — integrated information theory — has recently been labeled as ‘pseudoscience’, which has caused a heated open debate. Here we discuss the case and argue that the theory is indeed unscientific because its core claims are untestable even in principle.

As emphasized by Milne, an observer ultimately depends on the transmission and reception of light signals for the measurement of natural lengths and periods remote from his world point. The laws of geometry which are obeyed when these lengths and periods are plotted on a space-time depend, inevitably, on assumptions concerning the dependence of light velocity on the spatial and temporal coordinates. A convention regarding light velocity fixes the geometry, and conversely. However, the convention of flat space-time implies nonintegrable “radar (...) distances” unless the concept of coordinate-dependent units of measure is employed. Einstein's space-time has the advantage of admitting a special reference system $\hat R$ with respect to which the aether fluid is at rest and the total gravitational field vanishes. A holonomic transformation from $\hat R$ to another reference systemR belonging to the same space-time introduces a nonpermanent gravitational field and holonomic aether motion. A nonholonomic transformation from $\hat R$ to a reference systemR* which belongs to a different space-time introduces a permanent gravitational field and nonholonomic aether motion. The arbitrariness of geometry is expressed by extending covariance to include the latter transformation. By means of a nonholonomic (or units) transformation it is possible, with the aid of the principle of equivalence, to obtain the Schwarzschild and de Sitter metrics from the Newtonian fields that would arise in a flat space-time description. Some light is thrown on the interpretation of cosmological models. (shrink)

Hegel gave various lecture series on aesthetics or the philosophy of art, but never published a book of his own on this topic. His famous works on aesthetics were compiled from transcripts of lectures. This volume now presents one transcript complete in English for the first time, with extensive introductory material.

William of Ockham discussed the fallacy of amphiboly twice in his writings. The first treatment was in his Expositio super libros Elenchorum, where he simply presents Aristotle’s treatment, updates it with some Latin examples, and tells us it is not too important, since we do not often run into cases of ambiguity of thiskind. Later, in his Summa logicae, however, he extends his treatment appreciably. He here includes under ambiguous statements philosophical and theological sentences which are improperly stated. Led by (...) Aristotle, Augustine and Anselm, Ockham finds that in their writings they give us instances of improper statements which need to be restated properly before they can be evaluated as true or false. These leads provide for Ockham a key to unlocking the teaching treasures of the Ancients. (shrink)
