Joining the ongoing academic debates around medical students’ alternative career choices, this research examines the role of family in medical school attendees’ entrepreneurial intention. Specifically, this study decomposes the multidimensionality of family embeddedness and highlights the mediated nature of the family–EI relationship. The empirical analysis relied on data from graduation year medical students from diverse geographical locations and from different institution types in China. These data were collected from a total of 687 questionnaires covering the basic information of individual, parents, (...) and family composition, as well as the measuring scale of EI. Examining medical students’ EI and its antecedents provide a dual-missing-link in the extant knowledge, i.e., it adds the medical school piece to the overall picture of university students’ EI, and equally important, it de-trivializes entrepreneurship from the extant theorizations of medical students’ career choices. This study also bears implications for educators, practitioners, and policymakers interested in better understanding EI of medical school attendees and family embeddedness. (shrink)

The objective of this essay is to forge a more explicit link between the “visual turn” and the “practice turn” in entrepreneurship research. Specifically, we explore three key aspects of mobilizing visual methods for studying entrepreneurship-as-practice, i.e., data sources, collection strategies, and analytical perspectives, highlighting the important theoretical and empirical promises that visual methods hold for said research. This essay bears implications for researchers and educators working at the intersection of entrepreneurship research, the practice theory, and visual methods.

Themistokles was ostracized in the late 470's, probably in spring 471 or 470; if we are to believe Thucydides, he did not write to Artaxerxes in Persia until 465 at the earliest. In some way or other his stay in Argos and visits to the rest of the Peloponnese, his wanderings in northern Greece, and his delay in Asia Minor must be extended to fill this gap of at least five years. There is evidence of a sort, there are arguments (...) good and bad for the lengthening or shortening of any of these episodes, but none of this evidence or argument is conclusive. Between 470 and 465 no event in Themistokles' life can be securely dated; there is no fixed chronological pattern into which a reconstruction of the political history of Athens and the Peloponnese during these years must fit. Since the reconstruction which I attempt here is itself based on evidence which is far from adequate, plausibility is the most that can be claimed for it or for the chronological scheme which I infer from it.

The average educated Greek, I am sure, knew the early history of Greece as well as the average educated European knows the history of modern Europe, and could no more separate Theopompos from the first Messenian War or put Pheidon after Kypselos than we can separate Wellington from Waterloo or make Frederick the Great follow Napoleon. The professional historian, antiquarian, or chronographer would know much more, but could readily distort what he knew in trying to impose some theoretical pattern on (...) the past. Where so many of our sources are theoretical and when they survive in fragments which are rarely substantial enough to show in detail the theory on which they worked, it is not easy to see through to the core of Greek belief on which they were based. But facts there were and in the main it was from them that the theorizing started. (shrink)

In Part I of this discussion I considered the nature and validity of the principle of respect for persons as distinguished from its practical import and application. Before I proceed to that second topic let me draw together in summary fashion the main points of the view I have put forward.

Professor Strawson's paper is refreshing in content as well as refreshingly intemperate. It is salutary to be reminded that even the Type Identity Theory does not entail physicalism as that doctrine is usually understood (since c-fiber firings are not by definition purely physical). And it's fun to consider versions of panpsychism. I can see why Strawson finds his position hard to classify (p. 7), and I sympathize. In my title I have cast my own vote for '?-ism' on the grounds (...) that any familiar label would be either misleading or unwieldy. My main purpose here is to assess Strawson's case for panpsychism and then to offer some objections to panpsychism, but first I want to answer an interesting and serious charge he makes against me.

The question of whether a fetus can experience pain is an immense challenge. The issue demands consideration of the physical and psychological basis of being and the relation between the two. At the center of this debate is the question of how it is that we are conscious, a question that has inspired the writing of some of our most brilliant contemporary philosophers and scientists, with one commentary suggesting surrender. In my earlier review I attempted to draw together the various (...) strands of thinking that had attacked the question of fetal pain and relate them back to the bigger question of consciousness. In their vituperative response, Benatar and Benatar bite off my finger before looking to where I am pointing. I will examine each of their criticisms and attempt to redirect the readers' interest towards examining the subjectivity of pain and the mediating links between physiology and experience. (shrink)

The sixth decade of this century may be considered a period of dynamic development of the Soviet ethics. In contrast with the post-revolutionary period, the ethics does not limit itself to a normative reflection, but starts also extensive studies in the theory of ethics. According to the authors of the present article, there are all reasons to believe that the marxist ethics will become a scientific discipline in a full sense of the word. The purpose of the article is not (...) to discuss all problems involved in the contemporary Soviet ethics, but above all to outline main problems and trends of its development. The authors distinguish following aspects of the ethical investigations: philosophical, sociological, social-psychological, axiological, pedagogical, historical, gnoseological, logical, and metaethical. Together with a critical evaluation of solutions of certain problems, they criticize some abstractive and ahistorical, in their opinion, approach to ethics which has been manifested above all in works of Y. A. Milner-Irinin and P. M. Egides. (shrink)

My discussion of this theme falls into two parts. In the first part, starting from the assumption that we do in fact tend to respond favourably to the idea, vague though it may be, that “persons are to be respected, simply as persons”, I endeavour to clear my mind a little about our warrant for speaking in this way; and to do this is at the same time to clarify in some measure our understanding of what such language means. But (...) of course, since it is the language of practical principle, or precept, there can be no full understanding of its meaning without a grasp of its “working value”, of its significance as a clue to the proper directing and assessing of conduct. The second, and briefer, part of the discussion, accordingly, which is reserved for a subsequent article, is devoted to the question of the practical import of the principle of respect, the sort of guidance that it may provide in the actual business of life.

This dissertation concerns the nature of spacetime. It is divided into two parts. The first part, which comprises chapters 1, 2, and 3, addresses ontological questions: does spacetime exist? And if so, are there any other spatiotemporal things? In chapter 1 I argue that spacetime does exist, and in chapter 2 I respond to modal arguments against this view. In chapter 3 I examine and defend supersubstantivalism—the claim that all concrete physical objects (tables, chairs, electrons and quarks) are regions of (...) spacetime. Four-dimensional spacetime, we are often told, ‘unifies’ space and time; if we believe in spacetime, then we do not believe that space and time are separately existing things. But that does not mean that there is no distinction between space and time: we still distinguish between the spatial aspects and the temporal aspects of spacetime. The second part of this dissertation, comprising chapter 4, looks at this distinction. How is it made? In virtue of what are the temporal aspects of spacetime temporal, rather than spatial? The standard view is that the temporal aspects of spacetime are temporal because they play a distinctive role in the geometry of spacetime. I argue that this view is false, and that the temporal aspects are temporal because they play a distinctive role in the geometry of spacetime and in the laws of nature. (shrink)

In their response to my article, Fracchia and Lewontin have not refuted any of my three principal objections to theirs; they have ignored altogether my suggestion that evolutionary game theory illustrates particularly clearly the benefits that neo-Darwinian concepts and methods can bring to the human behavioral sciences; and they have attributed to me a version of “methodological individualism” to which I do not subscribe. It is, as is usual at this stage of a Kuhnian paradigm shift, too soon to say (...) how much selectionist theory can contribute to the human behavioral sciences in general and comparative sociology in particular. But selectionism’s critics achieve nothing by alleging that its proponents are committed to propositions to which they do not in fact assent and deny propositions with which they in fact agree.

I was prompted to write a book by re-reading Republic, Leviathan, and The Communist Manifesto for the first time in half a century and wondering how well they would stand up in the light of what present-day sociologists can fairly claim to know that Plato, Hobbes, and Marx did not. None of them were doing social science as that term is nowadays understood. But all three advance conclusions derived from evidence for how human beings do, or would, or might, behave (...) under different environmental and historical conditions. If these arguments are bad ones, this will presumably undermine the larger purposes which the three texts are intended to serve. Or will it? (shrink)

I should like to express my gratitude to my supervisor, Professor H. Schultink, whose criticisms and careful reading helped me to improve considerably upon the clarity of exposition while I wrote this study, and whose seemingly innocent requests to elaborate confronted me time and again with the need of revising or abandoning ideas I thought stood on firm ground. His support, and Dr. M. C. van den Toom's gratefully acknowl edged willingness to read and evaluate the manuscript enabled me to (...) present this work as a thesis in the University of Utrecht. In more than one way, lowe a debt to Albert Kraak, Professor of Linguistics in the University of Nijmegen. His inspiring enthusiasm awakened my interest in linguistics when I was a student of his. He in troduced me to transformational grammar at a time when it seemed almost improper to talk about it, and the stimulating experience of writing a book on Dutch syntax together with him taught me invaluable lessons. I should also like to thank my friend and colleague Henk Verkuyl, to gether with whom I prepared an article on the subject of measuring duration in Dutch. Without our stimulating discussions on the subject, the fourth chapter of this study could never have been written in the present form. I am also indebted to him for criticisms and helpful suggestions. At an early stage I profited greatly from discussions with Pieter A. M. (shrink)

We were led, at the close of the last paper, to the conclusion that the moral judgment lays claim to a knowledge of what is unknowable. It is not merely that our volition is imperfect, that the act of necessity falls short of what we know to be right. This seems bad enough; but the plight in which we actually find ourselves is even worse. The paradox is that we never know, and never can know, in any particular situation, what (...) it is really right to do. We know indeed that it is always right, really and absolutely right, to do what we believe to be right. For a man to act “against his conscience,” after all possible thought has been taken for its enlightenment, we know to be morally wrong. But this knowledge is purely formal and gives no clue to the matter of moral obligation. It tells us what is common alike to any and every case of moral duty; it does not tell us what we ought to do. For the right that we will cannot be merely the rightness of willing it. What I ought to do cannot be merely that I ought to do it. Now our beliefs and judgments as to material rightness, i.e. as to what it is right to do in a concrete situation, are notoriously liable to error. So we seek for a criterion by which to test our variable and fallible judgments, a criterion of what is really right. But the search is doomed to failure; we can only test beliefs by beliefs, our former beliefs by our later, the beliefs of one man or society or age by those of others. (shrink)

I Venture to take as the subject for our consideration the philosophical study of politics. However imperfect the treatment of such a subject, it seems to me opportune that attention should at this point of time be directed to the question. The study of politics is of increasing importance in the curricula of our universities and in general adult education. There is also the plain fact that we live in times when a deep unrest of spirit and a great variety (...) of experiment challenge ideas and institutions which have received wide acceptance. There has been, in short, a return to politics. It is well that we should consider afresh the value of the study and the methods by which it is studied. (shrink)

While reflecting recently on what the historian means by greatness, I was led to examine Croce's theory of economic action. It seemed to promise an answer to the troublesome problem of the relationship between greatness and moral goodness. How those hopes were disappointed will be explained presently, but Croce's theory must first be considered on its merits. I shall confine the discussion as far as possible to Croce's philosophy of the practical, avoiding any detailed reference, e.g., to the somewhat artificial (...) parallelism within the dialectic of the spirit between the forms of theoretical and those of practical activity. Since, however, Croce teaches—and his practice is in accordance with his teaching—that any severance of part from whole does violence to philosophy, it will be necessary to touch on certain larger questions before we close.

We have been led by our preliminary survey to acknowledge the autonomy of the moral life. The Tightness of an action is something that is sui generis and ultimate. It is vain to seek a reason for the rightness other than the Tightness itself. To the question, “Why ought I to do what I ought?” the only answer is, “Because I ought to do it.” 1 It is with rightness as with truth: Vera idea est norma sui et falsi. In (...) any moral situation, we intuitively judge what it is right to do, and in judging recognize that the obligation to do it is unconditional. That we possess this capacity is what is meant by saying that we are moral beings. (shrink)

This book is both extraordinarily useful and wonderfully beautiful. It provides a sympathetic and articulate account of the basic philosophical and religious theory of Hindu polytheism, an analysis of some of its fundamental concepts, a systematic ordering and explanation of the major deities with their various names and symbols, and a clear picture of the structure and development of Hindu thought. The Sanskrit texts are printed separately, and there is a set of fine black-and-white plates. I can't imagine a more (...) delightful, or more useful, basic reference work on the subject.

In its original form this was Bonhoeffer's first work, presented as a theological dissertation when the author was only twenty-one. It has been very influential on proponents of "religionless Christianity" among the Continental theologians. The argument is compressed and often elliptical, exceedingly difficult to grasp. Bonhoeffer follows Tonnies' distinction between society and community, holding that the religious community is a community of will which admits no end outside itself, but whose telos, God, is its boundary. It is a structure of (...) meaning rather than a structure of purpose, uniting persons in an I-Thou relationship in which they assume the relative independence of a Leibnitzian monad.

This article challenges the current scholarly consensus that Suetonius wrote the Divus Iulius regardless of Plutarch. Closer examination of the Caesar-biographies shows which influence Plutarch has exerted by his biographic works on Suetonius and reveals that the dominant position in the classical studies is obsolete. This paper scrutinises not only clearly defined knowledge of the Quellenforschung, but illuminates also the role model of Plutarch. Before it is possible to assess the dependence of the Divus Iulius from the Καισαρ, I will (...) reopen the case of the composition dates, examine the literary circles as a space of interaction and look on Plutarch’s reception in Rome.

The analysis presented here covers a vast number of aspects, or sub-questions, of the maddeningly frustrating general question, How can I be sure that, every time I believe something, such as that there are rocks, I am not deceived into so believing by a modern version of Descartes’ evil demon, i.e., a mad scientist who, by means of electrodes implanted in my brain, manipulates my beliefs? Numerous aspects are also analyzed of the standard objections to scepticism, such as G. E. (...) Moore’s common-sense affirmations of knowledge that he has two hands and the ad hominem question, If no beliefs are justified, then why do you, the sceptic, believe such propositions as the proposition that no beliefs are justified? The author not only concludes in favor of scepticism, but also erects strong arguments supporting the contention that, even apart from knowledge or supposed knowledge, truth itself is impossible. He concludes that, "to solve our problems [about the unwarranted use of terms such as ‘know', ‘believe', and ‘true'], either a new language should be developed and made available or at least an existing language should be radically changed in creative ways."—W.G.

Seemingly, every mental act has a content or subject-matter. When I think, imagine, or hear, there appears to be a content or subject-matter of my thinking, imagining, or hearing. Now, what the difference is between this kind of content and the content of nonmental containers or containings, is a question which has beguiled even those thinkers, such as Ryle in England and physicalists in America, who are disinclined to recognize the mental as a separate ontic domain. When the problem of (...) isolating the nature of mental content or subject-matter was revived in the 19th century, Franz Brentano followed the Scholastics in calling these contents "intentions." The editor of the present volume, while noting that the concept of "intentionality has played a very central role in such philosophical movements as phenomenology, existentialism, and neo-Scholasticism," brings out the fact that this concept also, in recent years, was taken up by "philosophers in the analytical tradition as a powerful conceptual tool...." Seminal writings on the nature of intentionality by Frege, Russell, Carnap, Hempel, Ryle, Quine, Chisholm, Wilfrid Sellars, Thomas Nagel, Aune, Linsky, Hintikka, and others are brought together in this well-organized anthology, along with an introduction, a supplement containing unpublished Sellars correspondence with David M.

Margolis, having previously published analytical examinations of Fact and Existence and Values and Conduct, now holds up to inspection Knowledge and Existence. This work is subtitled An Introduction to Philosophical Problems, but it is an introduction in a special sense only. As the author himself states, "I have deliberately omitted nearly all mention of the views of particular philosophers." In other words, the text consists entirely of conceptual investigation, with no leavening of stories on how each puzzlement dealt with evolved (...) historically as a puzzlement. This is all very well for trained philosophers, whose relish for the kind of sorting out here offered is already developed; for them, this is a rewarding introduction to one philosopher’s unraveling of the problems that have bewitched them. For beginners, however, it is too difficult. Margolis’s chapter headings are an exquisite tour de force, linking opposites, correlatives, and other conjunctives in the neat, spare duos that Margolis cherishes: Knowledge and Belief, Perception and Sensation, Doubt and Certainty, Existence and Reality, Identity and Individuation, Action and Event, Language and Truth, Mind and Body, and Facts and Values. The book contains no footnotes. A tightly written Epilogue of six pages serves as "a checklist of sorts," listing "some of the key views" that the author supports or rejects. The index is exemplary.—W. G. (shrink)

The editors are concerned in this book to avoid both Scylla and Charybdis. In their preface, they state: "Some introductory philosophy texts are introductory in name only.... No wonder students struggling to understand such books become convinced... that philosophy is a subject wholly unintelligible except to a few compulsive adepts and completely irrelevant to life outside of the classroom. On the other hand,... other introductory philosophy texts are philosophical in name only because they contain no technical philosophy. Not surprisingly students (...) reading such books... find them hollow and conclude philosophy is not worth serious study." Striving to bridge the gap, the editors include in the readings some lucid philosophical classics, such as Descartes’ Meditations I and II, passages from deeply probing literature such as Dostoevsky’s The Grand Inquisitor, and choice recent philosophical discussions such as the section on free will in Stace’s Religion and the Modern Mind. Lively but significant readings are included on six areas: freedom or determinism, God and religion, morality and society, mind and body, knowledge and science, and art and society. The final readings on each area present "Contemporary Issues." For example, the readings on art and society end with the opinion of the U.S. Supreme Court on Fanny Hill, E. M. Forster’s essay on art for art’s sake, and a discussion by Barrows Dunham of art for man’s sake.—W. G. (shrink)

Structuralism, in so far as its essence can be pinned down, seems to be the view that the surface aspects of social phenomena are best explained in terms of complex, elusive, below-the-surface "structures," patterns, or model systems. Examples of such underlying structures are the unconscious motivation schemes of individuals, a taken-for-granted economic order, customs of social strata, ingrained moral philosophies, and religious institutions. The De Georges’ pioneer sourcebook [[sic]] presents selections, infused with the structuralist viewpoint, from the writings of Marx, (...) Freud, and the linguist Ferdinand de Saussure, who are structuralism’s patriarchs; Claude Lévi-Strauss, its present high priest; Roman Jakobson, teacher of structural linguistics at Harvard and M.I.T.; Louis Althusser, who rejects affiliation with structuralism; and four others. Some of these selections include extremely difficult passages, in which the authors seem to be striving to squeeze a deep disclosure out of a surface act or function. Other selections are clearer, somewhat smoother, and more convincing. A well-made index concludes the volume.—W. G. (shrink)

In debates about genetic testing of children, as well as about disclosing unsolicited findings (UFs) of pediatric exome sequencing, respect for future autonomy should be regarded as a prima facie consideration for not taking steps that would entail denying the future adult the opportunity to decide for herself about what to know about her own genome. While the argument can be overridden when other, morally more weighty considerations are at stake, whether this is the case can only be determined in (...) concrete cases. Importantly, when children grow into adolescents, respect for future autonomy will have to give way to respecting their emerging autonomy. When pediatric exome sequencing is done for complex conditions not involving developmental delay, respect for the child’s future or emerging autonomy should be a primary consideration for those charged with deciding on behalf of the child. Building on what Emanuel and Emanuel have termed the ‘deliberative model’ of shared decision making, we argue that if parents fail to give these considerations their due, professionals should actively invite them to do so. Taking a directive stance may be needed in order to make sure that the future or emerging autonomy of the child are duly considered in the decision-making process, but also to help the parents and themselves to shape their respective roles as responsible care-givers.

The present paper develops arguments for the need to formulate the basic theories of physics in terms of a six-dimensional manifold, as opposed to the four-dimensional space-time continuum of conventional theory. Employing a purely classical approach, some of the dynamical consequences of such a formulation with regard to both electrodynamics and gravitation are evaluated. The results lead to interesting implications with regard to various questions such as the occurrence and importance of superluminal particles, the existence of two or more physically (...) distinct time scales, and the variation of the gravitational coupling constant G and the law of energy conservation. The analysis also suggests a physical interpretation of the additional coordinates that occur in the metric. (shrink)

At the same time that social justice concerns are on the rise on college campuses, empathy levels among US college students are falling. Social injustice resulting from organizational decisions and actions causes profound and unnecessary human suffering, and research to understand antecedents to these decisions and actions lacks attention. Empathy represents a potential tool and critical skill for organizational decision-makers, with empirical evidence linking empathy to moral recognition of ethical situations and greater breadth of understanding of stakeholder impact and improved (...) financial success. This study explores the potential relationship between empathy and social justice, using a multifaceted operationalization of social justice, which includes management actions and social sympathies. Results broadly support the positive empathy and social justice relationship and suggest higher education interventions to develop empathy in college business students. (shrink)

Patient safety has only recently been subjected to wide-spread systematic study. Healthcare differs from other high risk industries in being more diverse and multi-contextual, and less certain and regulated. Also many patient safety problems are low-frequency events associated with many, varied contributing factors. The subject of this paper is the epistemology of patient safety (the science of the method of finding out about patient safety). Patient safety research is considered here on the background of a risk management framework which requires (...) researchers to: • Understand the context - as a subset of healthcare quality, services and systems research, with technical and human behavioural (cultural) components and a range of external and internal organisational influences, a wide range of research disciplines is necessary • Identify the risks - identify the things that go wrong and the frequency and nature of different types of incidents from sources such as medical record review, observational studies, audit, incident and medico-legal reports • Analyse the risks - deconstruct the things that go wrong, identifying contributing factors and trying to detect trends and patterns in contributing factors, detection, mitigation factors, ameliorating factors and actions taken to reduce risk • Evaluate the risks - decide on priorities, identifying preventive and corrective strategies and judging the risk- and cost-benefit of potential corrective strategies such as standardisation or simplification of a process or device • Manage the risk - evaluate and scope preventive and/or corrective strategies and then implement these, or place the problem on a risk register pending solution, or accept that what is needed is unaffordable • Communicate and consult - use interactive sessions, audit, on-going feedback, reminders and patient mediated prompts • Monitor and review the state of the problem - get baseline trends and patterns so that changes can be tracked and properly attributed to an intervention A hierarchy of levels of evidence has been proposed for clinical research and we argue that insufficient weighting has been given to lower ranked levels of research and to qualitative research, although critical interpretive synthesis is now gaining acceptance in mainstream thinking (e.g. by the Cochrane Collaboration). Fundamental challenges remain including how to grasp the elusive concept of patient safety, how to quantify, characterise and cost the problems, how to judge the extent to which harm can be attributed to errors, violations or system failures, how to identify contributing factors and the extent to which they can be implicated, how to judge whether incidents or their precursors are preventable, how to generate strong evidence to make healthcare safer and how to translate research into practice. Future directions include addressing the mundane as well as rare, dramatic events, and developing further research in non-hospital settings and in developing countries. In summary, a mixture of qualitative and quantitative methods, using information from all available data sources and combining retrospective, real time and prospective study designs, is necessary to address some of the more difficult patient safety problems.

ABSTRACT Global biodiversity declines are increasingly recognized as profound ecological and social crises. In areas subject to colonialization, these declines have advanced in lockstep with settler colonialism and imposition of centralized resource management by settler states. Many have suggested that resurgent Indigenous-led governance systems could help arrest these trends while advancing effective and socially just approaches to environmental interactions that benefit people and places alike. However, how dominant management and conservation approaches might be decolonized (i.e., how their underlying colonial structure (...) might be addressed, transformed, and replaced) is not always clear. Here, we describe a ‘Decolonial Model of Environmental Management and Conservation’ as an alternative paradigm to dominant approaches of conservation and management. The tenets of the model describe characteristics that might be expected of decolonized management, contrasted with those of dominant state-led approaches such as those embedded in the North American Model of Wildlife Conservation. The model does not prescribe how Indigenous governments or communities ought to govern their own territories, but instead offers insights into how external management and conservation agencies and practitioners might support (or stop impeding) Indigenous-led governance. We illustrate the model with a conservation ‘bright spot’: grizzly bear stewardship in the area now referred to as the Great Bear Rainforest in British Columbia, Canada, with a focus on work led by or in collaboration with, and within the territories of, the Haíɫzaqv, Kitasoo/xai’xais, Nuxalk, and Wuikinuxv First Nations. While acknowledging the important context-specific variability among place-based management and conservation applications, we also discuss the model’s broader applicability. (shrink)

We have synthesized a 582,970-base pair Mycoplasma genitalium genome. This synthetic genome, named M. genitalium JCVI-1.0, contains all the genes of wild-type M. genitalium G37 except MG408, which was disrupted by an antibiotic marker to block pathogenicity and to allow for selection. To identify the genome as synthetic, we inserted "watermarks" at intergenic sites known to tolerate transposon insertions. Overlapping "cassettes" of 5 to 7 kilobases (kb), assembled from chemically synthesized oligonucleotides, were joined by in vitro recombination to produce intermediate (...) assemblies of approximately 24 kb, 72 kb ("1/8 genome"), and 144 kb ("1/4 genome"), which were all cloned as bacterial artificial chromosomes in Escherichia coli. Most of these intermediate clones were sequenced, and clones of all four 1/4 genomes with the correct sequence were identified. The complete synthetic genome was assembled by transformation-associated recombination cloning in the yeast Saccharomyces cerevisiae, then isolated and sequenced. A clone with the correct sequence was identified. The methods described here will be generally useful for constructing large DNA molecules from chemically synthesized pieces and also from combinations of natural and synthetic DNA segments. 10.1126/science.1151721.

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.
