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.

1 Evidence-based policy requires researchers to provide the answers to ecological questions that are of interest to policy makers. To find out what those questions are in the UK, representatives from 28 organizations involved in policy, together with scientists from 10 academic institutions, were asked to generate a list of questions from their organizations. 2 During a 2-day workshop the initial list of 1003 questions generated from consulting at least 654 policy makers and academics was used as a basis for (...) generating a short list of 100 questions of significant policy relevance. Short-listing was decided on the basis of the preferences of the representatives from the policy-led organizations. 3 The areas covered included most major issues of environmental concern in the UK, including agriculture, marine fisheries, climate change, ecosystem function and land management. 4 The most striking outcome was the preference for general questions rather than narrow ones. The reason is that policy is driven by broad issues rather than specific ones. In contrast, scientists are frequently best equipped to answer specific questions. This means that it may be necessary to extract the underpinning specific question before researchers can proceed. 5 Synthesis and applications. Greater communication between policy makers and scientists is required in order to ensure that applied ecologists are dealing with issues in a way that can feed into policy. It is particularly important that applied ecologists emphasize the generic value of their work wherever possible. (shrink)

After he has been condemned to death, Socrates spends a few minutes talking to the jurors before he is taken away. First, he rebukes those who voted against him for resorting to using the court to kill him when they could have waited and let nature do the same job very soon anyhow, for Socrates is an old man. He next contrasts the evils to which his accusers have resorted to his own unbending resolve never to resort to shameful actions, (...) even though in this case such things might have saved his life. Then he prophesies to those jurors that younger men will make their lives far more difficult than ever Socrates did, and thus strips from them any notion they may have had that they gained anything by condemning him.

The claim that the citizen's duty is to “persuade or obey” the laws, expressed by the personified Laws of Athens in Plato's Crito, continues to receive intense scholarly attention. In this article, we provide a general review of the debates over this doctrine, and how the various positions taken may or may not fit with the rest of what we know about Socratic philosophy. We ultimately argue that the problems scholars have found in attributing the doctrine to Socrates derive from (...) an anachronistic and erroneous understanding of Socrates as a kind of libertarian.

In his interrogation of Meletus in Plato’s version of Socrates’ defense speech, Socrates offers an interesting argument that promises to provide important evidence for his views about crime and punishment—if only we can understand how the argument is supposed to work. It is our project in this paper to do that. We argue that there are two main problems with the argument: one is that it is not obvious how to make the argument valid; the other is that the argument (...) seems to rely on a distinction that Socrates himself rejects ––a distinction between voluntary and involuntary wrongdoing. Earlier discussions of the argument require Socrates to be using a premise here that he regards as false. In this paper, we argue that Socrates actually regards the critical premise as true, and thus we end up providing a significantly new interpretation of Socrates’ view that all wrongdoing is involuntary. We claim, that even this position must accommodate the idea that some people really do voluntary harm to others. (shrink)

This book's importance is derived from three sources: careful conceptualization of teacher induction from historical, methodological, and international perspectives; systematic reviews of research literature relevant to various aspects of teacher induction including its social, cultural, and political contexts, program components and forms, and the range of its effects; substantial empirical studies on the important issues of teacher induction with different kinds of methodologies that exemplify future directions and approaches to the research in teacher induction.

There has been little scholarly attention given to explaining exactly how and why Socrates thinks that wrongdoing damages the soul. But there is more than a simple gap in the literature here, we shall argue. The most widely accepted view of Socratic moral psychology, we claim, actually leaves this well-known feature of Socrates’ philosophy absolutely inexplicable. In the first section of this paper, we rehearse this view of Socratic moral psychology, and explain its inadequacy on the issue of the damaging (...) consequences of wrongdoing. We then go on to provide our own account of the way in which injustice damages the soul, and then draw conclusions about how Socratic moral psychology should be understood. (shrink)

This chapter contains sections titled: The Prudential Paradox The Meno Argument Socrates’ Argument against “The Many” in the Protagoras Knowledge and Belief What Endows an Object with the Power of Appearance? Does Socrates have the Metrētikē Technē? The Moral Paradox Socrates, Plato, and Aristotle Note.

Socrates' moral psychology is widely thought to be 'intellectualist' in the sense that, for Socrates, every ethical failure to do what is best is exclusively the result of some cognitive failure to apprehend what is best. Until publication of this book, the view that, for Socrates, emotions and desires have no role to play in causing such failure went unchallenged. This book argues against the orthodox view of Socratic intellectualism and offers in its place a comprehensive alternative account that explains (...) why Socrates believed that emotions, desires and appetites can influence human motivation and lead to error. Thomas C. Brickhouse and Nicholas D. Smith defend the study of Socrates' philosophy and offer an alternative interpretation of Socratic moral psychology. Their novel account of Socrates' conception of virtue and how it is acquired shows that Socratic moral psychology is considerably more sophisticated than scholars have supposed. (shrink)

In this paper we argue that Socrates is a cognitivist about emotions, but then ask how the beliefs that constitute emotions can come into being, and why those beliefs seem more resistant to change through rational persuasion than other beliefs.

Thomas Brickhouse and Nicholas Smith offer a comprehensive historical and philosophical interpretation of, and commentary on, one of Plato's most widely read works, the Apology of Socrates. Virtually every modern interpretation characterizes some part of what Socrates says in the Apology as purposefully irrelevant or even antithetical to convincing the jury to acquit him at his trial. This book, by contrast, argues persuasively that Socrates offers a sincere and well-reasoned defense against the charges he faces. First, the authors (...) establish a consensus of ancient reports about Socrates ' moral and religious principles and show that these prohibit him from needlessly risking the condemnation of the jury. Second, they consider each specific claim made by Socrates in the Apology and show how each can be construed as an honest effort to inform the jurors of the truth and to convince them of his blamelessness. The arguments of this book are informed by a critical review of the scholarly literature and careful attention to the philosophy expressed in Plato's other early dialogues. (shrink)

As engineering applications require management of ever larger volumes of data, ontologies offer the potential to capture, manage, and augment data with the capability for automated reasoning and semantic querying. Unfortunately, considerable barriers hinder wider deployment of ontologies in engineering. Key among these is lack of a shared top-level ontology to unify and organise disparate aspects of the field and coordinate co-development of orthogonal ontologies. As a result, many engineering ontologies are limited to their scope, and functionally difficult to extend (...) or interoperate with other engineering ontologies. This paper demonstrates how the use of a top-level ontology, specifically the Basic Formal Ontology (BFO), greatly facilitates interoperability of multiple engineering-related ontologies. We constructed a system of formal linked ontologies by re-engineering legacy ontologies to be conformant with BFO and developing new BFO-conformant ontologies to capture knowledge in the engineering design, enterprise, human factors, manufacturing, and application domain of additive manufacturing. The resulting Integrated Framework for Additively Manufactured Products (IFAMP), including the body knowledge instantiated on its basis, serve as the basis for a proposed Design with Additive Manufacturing Method (DWAM), which we believe can support the design of innovative products with semantically enhanced ideation tools and enhanced access to application domain knowledge. The method and its facilitation through the ontological framework are demonstrated using a case study in medicine. (shrink)

In the Protagoras, Socrates argues that each of the virtue-terms refers to one thing (: 333b4). But in the Laches (190c8–d5, 199e6–7), Socrates claims that courage is a proper part of virtue as a whole, and at Euthyphro 11e7–12e2, Socrates says that piety is a proper part of justice. But A cannot be both identical to B and also a proper part of B – piety cannot be both identical to justice and also a proper part of justice. In this (...) paper we argue that coherent sense can be made of Socrates'' apparently conflicting claims. The key to understanding Socrates'' position, we will argue, is the central role of wisdom among the virtues. It is through the relationship of each virtue to wisdom that each may be said to be the same as all of the others, on the one hand, and also that some virtues may be regarded as proper parts of some other virtues, or as proper parts of virtue in general, on the other.

Three-dimensionalists , sometimes referred to as endurantists, think that objects persist through time by being “wholly present” at every time they exist. But what is it for something to be wholly present at a time? It is surprisingly difficult to say. The threedimensionalist is free, of course, to take ‘is wholly present at’ as one of her theory’s primitives, but this is problematic for at least one reason: some philosophers claim not to understand her primitive. Clearly the three-dimensionalist would be (...) better off if she could state her theory in terms accessible to all. We think she can. What is needed is a definition of ‘is wholly present at’ that all can understand. in this paper, we offer one. (shrink)

Socrates is one of the most important yet enigmatic philosophers of all time; his fame has endured for centuries despite the fact that he never actually wrote anything. In 399 B.C.E., he was tried on the charge of impiety by the citizens of Athens, convicted by a jury, and sentenced to death (ordered to drink poison derived from hemlock). About these facts there is no disagreement. However, as the sources collected in this book and the scholarly essays that follow them (...) show, several of even the most basic facts about these events were controversial in antiquity, and the questions persist today: How and why was Socrates brought to trial? Why did the jurors, members of the world's first democracy, find him guilty? When he was given an opportunity to escape execution, why did he refuse to do so and instead accept the punishment that he and his friends agreed was unjustly assigned to him? How exactly did Socrates die? Differences of opinion on these and other issues continue to arouse our curiosity and to challenge new generations of students and scholars. The Trial and Execution of Socrates: Sources and Controversies is the first work to collect in one place all of the major ancient sources on Socrates' death--those of both his critics and his defenders--as well as recent scholarly views. Part I includes new translations of Plato's Euthyphro, Apology, Crito, and the death scene from Phaedo, as well as other ancient sources that shed light on Socrates' trial and execution. Part II features some of the most influential recent scholarship on this historically momentous event with work by M. F. Burnyeat, Robert Parker, Mark L. McPherran, Thomas C. Brickhouse and Nicholas D. Smith, Richard Kraut, Christopher Gill, and Enid Bloch (whose essay is published here for the first time). Ideal for undergraduate surveys of ancient Greek philosophy and upper-level courses on Socrates and Socratic philosophy, this unique collection provides an unprecedented look into the many perplexing questions surrounding the trial and execution of this remarkable man.

In our reply to Rowe, we explain why most of what he criticizes is actually the product of his misunderstanding our argument. We begin by showing that nearly all of his Part 1 misconceives our project by defending a position we never attacked. We then question why Rowe thinks the distinction we make between motivational and virtue intellectualism is unimportant before developing a defense of the consistency of our views about different desires. Next we turn to Rowe’s criticisms of our (...) account of the prudential paradox and show these criticisms to rest on a misunderstanding. We close with some remarks about the implausibility and textual problems Rowe faces in denying that Socrates recognized a role for painful punishments. (shrink)

Mainstream nursing history often positions itself in opposition to philosophy and many nursing historians are reticent of theorizing. In the quest to illuminate the lives of nurses and women current historical approaches are driven by reformist aspirations but are based on the conception that nursing or caring is basically good and the timelessness of universal values. This has the effect of essentialising political categories of identity such as class, race and gender. This kind of history is about affirmation rather than (...) friction and about the conservation of memory and musealization. In contrast, we will focus on how we imagine nursing history could be used as a philosophical, critical perspective to challenge the ongoing transformations of our societies. Existing reality must be confronted with strangeness and the historically different can assume the function of this counterpart, meaning present and past must continuously be set in relation to each other. Thus, critical history is always the history of the present but not merely the pre‐history of the present – critique must rather present different realities and different certainties. In this paper, we use this approach to discuss the implementation of the nursing process (NP) in Germany. The nursing process appears to be a technology that helped to set up an infrastructure ‐ or assemblage ‐ to transform nursing interventions into a commodity exchangable between consumers and nurses in a free market. In our theoretical perspective, we argue that NP was a step in the realization of the German ordoliberal program, a specific variety of neoliberalism. In order to implement market‐orientation in the healthcare system it was necessary to transform hospitals into calculable spaces and to make all performances in the hospital calculable. This radically transformed not just the systems, but the ways in which nurses and patients conveived of themselves. (shrink)

Plato's Euthyrphro, Apology, andCrito portray Socrates' words and deeds during his trial for disbelieving in the Gods of Athens and corrupting the Athenian youth, and constitute a defense of the man Socrates and of his way of life, the philosophic life. The twelve essays in the volume, written by leading classical philosophers, investigate various aspects of these works of Plato, including the significance of Plato's characters, Socrates's revolutionary religious ideas, and the relationship between historical events and Plato's texts.

In Sartre and the Drug Connection, Carole Haynes-Curtis claims that previous commentators on the philosopher's writings have failed to recognize the significance of the impact of a mescalin experiment on Sartre's early philosophical perspective. ‘The residual effects of this nightmarish experience’, Haynes-Curtis claims, ‘haunted him for many years to come’, and was essentially the result of Sartre undergoing what, in modern parlance, is sometimes called a ‘Bad Trip’.

Abstract: We propose a view of vagueness as a semantic property of names and predicates. All entities are crisp, on this semantic view, but there are, for each vague name, multiple portions of reality that are equally good candidates for being its referent, and, for each vague predicate, multiple classes of objects that are equally good candidates for being its extension. We provide a new formulation of these ideas in terms of a theory of granular partitions. We show that this (...) theory provides a general framework within which we can understand the relation between vague terms and concepts and the corresponding crisp portions of reality. We also sketch how it might be possible to formulate within this framework a theory of vagueness which dispenses with the notion of truth-value gaps and other artifacts of more familiar approaches. Central to our approach is the idea that judgments about reality involve in every case (1) a separation of reality into foreground and background of attention and (2) the feature of granularity. On this basis we attempt to show that even vague judgments made in naturally occurring contexts are not marked by truth-value indeterminacy. We distinguish, in addition to crisp granular partitions, also vague partitions, and reference partitions, and we explain the role of the latter in the context of judgments that involve vagueness. We conclude by showing how reference partitions provide an effective means by which judging subjects are able to temper the vagueness of their judgments by means of approximations. (shrink)

We have a variety of different ways of dividing up, classifying, mapping, sorting and listing the objects in reality. The theory of granular partitions presented here seeks to provide a general and unified basis for understanding such phenomena in formal terms that is more realistic than existing alternatives. Our theory has two orthogonal parts: the first is a theory of classification; it provides an account of partitions as cells and subcells; the second is a theory of reference or intentionality; it (...) provides an account of how cells and subcells relate to objects in reality. We define a notion of well-formedness for partitions, and we give an account of what it means for a partition to project onto objects in reality. We continue by classifying partitions along three axes: (a) in terms of the degree of correspondence between partition cells and objects in reality; (b) in terms of the degree to which a partition represents the mereological structure of the domain it is projected onto; and (c) in terms of the degree of completeness with which a partition represents this domain. (shrink)

In response to our target article, many of the commentators concentrated on our notion of Residual Normality. In our response, we focus on the questions raised by this idea. However, we also examine broader issues concerning the importance of incorporating a realistic theory of the process of development into explanations of developmental deficits.

In this paper we propose a formal theory of partitions (ways of dividing up or sorting or mapping reality) and we show how the theory can be applied in the geospatial domain. We characterize partitions at two levels: as systems of cells (theory A), and in terms of their projective relation to reality (theory B). We lay down conditions of well-formedness for partitions and we define what it means for partitions to project truly onto reality. We continue by classifying well-formed (...) partitions along three axes: (a) degree of correspondence between partition cells and objects in reality; (b) degree to which a partition represents the mereological structure of the domain it is projected onto; and (c) degree of completeness and exhaustiveness with which a partition represents reality. This classification is used to characterize three types of partitions that play an important role in spatial information science: cadastral partitions, categorical coverages, and the partitions involved in folk categorizations of the geospatial domain.

Punk Pedagogies: Music, Culture and Learning brings together a collection of international authors to explore the possibilities, practices and implications that emerge from the union of punk and pedagogy. The punk ethos--a notoriously evasive and multifaceted beast--offers unique applications in music education and beyond, and this volume presents a breadth of interdisciplinary perspectives to challenge current thinking on how, why and where the subculture influences teaching and learning. As (punk) educators and artists, contributing authors grapple with punk's historicity, its pervasiveness, (...) its (dis)functionality and its messiness, making Punk Pedagogies relevant and motivating to both instructors and students with proven pedagogical practices.

I defend some of Gilbert’s central claims about our capacity jointly to commit ourselves, and what follows from an exercise of it. I argue that, to explain these claims, we do not need to suppose, as Gilbert does, that we ever are jointly committed, that is, jointly in a state of being committed. I offer a diagnosis of why the gratuitousness of this supposition has been overlooked.

This paper presents an axiomatic formalization of a theory of top-level relations between three categories of entities: individuals, universals, and collections. We deal with a variety of relations between entities in these categories, including the sub-universal relation among universals and the parthood relation among individuals, as well as cross-categorial relations such as instantiation and membership. We show that an adequate understanding of the formal properties of such relations – in particular their behavior with respect to time – is critical for (...) geographic information processing. The axiomatic theory is developed using Isabelle, a computational system for implementing logical formalisms. All proofs are computer verified and the computational representation of the theory is available online. (shrink)

“Doomsday prepping” is a phenomenon which involves preparing for feared societal collapse by stockpiling resources and readying for self-sufficiency. While doomsday prepping has traditionally been reported in the context of extremists, during the COVID-19 pandemic, excessive stockpiling leading to supply shortages has been reported globally. It is unclear what psychological or demographic factors are associated with this stockpiling. This study investigated doomsday prepping beliefs and behaviors in relation to COVID-19 proximity, demographics, coping strategies, psychopathology, intolerance of uncertainty (IU), and personality (...) in 384 participants (249 female) in an online study. Participants completed a number of questionnaires including the Post-Apocalyptic and Doomsday Prepping Beliefs Scale and a scale designed for the current study to measure prepping in the context of COVID-19. These were analyzed using ANOVAs, correlational, and mediation analyses to examine relationships between psychometric variables and stockpiling. Prepping beliefs and behaviors were higher in males than females and positively associated with anxiety, obsessive-compulsive symptoms, IU, and traditional masculinity traits. Older age, male gender, obsessive-compulsive symptoms, and traditional masculinity predicted unique variance in prepping. The relationship between gender and stockpiling was mediated by social learning (witnessing other people panic buying) and the perceived threat of COVID-19 (doomsday interpretations) while proximity and personal vulnerability to COVID-19 were non-significant. Results indicate that panic buying was influenced more by witnessing others stockpiling, personality, and catastrophic thinking rather than by proximity to danger. Education could target these factors in ongoing waves of the pandemic or future catastrophes. (shrink)

This chapter concerns the ethics and metaphysics of occupations, such as teacher, waiter, and priest. It argues that teacher is a functional kind, but teachers are not functional objects. If you are a practising teacher, it is likely that you perform a function and serve a purpose, that of imparting knowledge and cultivating minds and skills. This is what teachers, generically, are for, and it is what your school is for. But it is not what you are for. Easily confused (...) senses of ‘job’ are distinguished: occupation, position, requirement, and function. The chapter explains that the requirements of your position and occupation do not entail ability, reasons, or fault (if not complied with), and that if you are not as your position and occupation require, you are not as you ought to be, but it does not follow that there is anything wrong with you. The chapter includes some metaphysical speculation about positions, and examines some sources of, and remedies for, workplace alienation and anxiety. (shrink)

Published in extended form as "Endurants and Perdurants in Directly Depicting Ontologies", -/- We propose an ontological theory that is powerful enough to describe both complex spatio-temporal processes and the enduring entities that participate in such processes. For this purpose we distinguish between ontologies and metaontology. Ontologies are based on very simple directly depicting languages and fall into two major categories: ontologies of type SPAN and ontologies of type SNAP. These represent two complementary perspectives on reality and result in distinct (...) though compatible systems of categories. In a SNAP (snapshot) ontology we have the enduring entities in a given domain as they exist to be inventoried at some given moment of time. In a SPAN ontology we have perduring entities such as processes and their parts and aggregates. We argue that both kinds of ontology are required, together with the meta-ontology which joins them together. On the level of meta-ontology we are able to impose constraints on ontologies of a sort which can support efficient processing of large amounts of data. (shrink)

We propose an ontological theory that is powerful enough to describe both complex spatio-temporal processes (occurrents) and the enduring entities (continuants) that participate in such processes. For this purpose we distinguish between meta-ontology and token ontologies. Token ontologies fall into two major categories: ontologies of type SPAN and ontologies of type SNAP. These represent two complementary perspectives on reality and result in distinct though compatible systems of categories. The meta-ontological level then describes the relationships between the different token ontologies. In (...) a SNAP (snapshot) ontology we have enduring entities such as substances, qualities, roles, functions as these exist to be inventoried at a given moment of time. In a SPAN ontology we have perduring entities such as processes and their parts and aggregates.

The theory of granular partitions is designed to capture in a formal framework important aspects of the selective character of common-sense views of reality. It comprehends not merely the ways in which we can view reality by conceiving its objects as gathered together not merely into sets, but also into wholes of various kinds, partitioned into parts at various levels of granularity. We here represent granular partitions as triples consisting of a rooted tree structure as first component, a domain satisfying (...) the axioms of Extensional Mereology as second component, and a mapping (called ’projection’) of the first into the second as a third component. We define ordering relations among granular partitions the resulting structures are called partition frames. We then introduce an axiomatic theory which sentences are interpreted in partition frames.

It is often assumed that similar domain-specific behavioural impairments found in cases of adult brain damage and developmental disorders correspond to similar underlying causes, and can serve as convergent evidence for the modular structure of the normal adult cognitive system. We argue that this correspondence is contingent on an unsupported assumption that atypical development can produce selective deficits while the rest of the system develops normally (Residual Normality), and that this assumption tends to bias data collection in the field. Based (...) on a review of connectionist models of acquired and developmental disorders in the domains of reading and past tense, as well as on new simulations, we explore the computational viability of Residual Normality and the potential role of development in producing behavioural deficits. Simulations demonstrate that damage to a developmental model can produce very different effects depending on whether it occurs prior to or following the training process. Because developmental disorders typically involve damage prior to learning, we conclude that the developmental process is a key component of the explanation of endstate impairments in such disorders. Further simulations demonstrate that in simple connectionist learning systems, the assumption of Residual Normality is undermined by processes of compensation or alteration elsewhere in the system. We outline the precise computational conditions required for Residual Normality to hold in development, and suggest that in many cases it is an unlikely hypothesis. We conclude that in developmental disorders, inferences from behavioural deficits to underlying structure crucially depend on developmental conditions, and that the process of ontogenetic development cannot be ignored in constructing models of developmental disorders. Key Words: Acquired and developmental disorders; connectionist models; modularity; past tense; reading. (shrink)
