There is a growing recognition, stemming from work with both vertebrates and invertebrates, that the capacity for neuronal regeneration is critically dependent on the local microenvironment. That environment is largely created by the non‐neuronal elements of the nervous system, the neuroglia. Therefore an understanding of how glial cells respond to injury is crucial to understanding neuronal regeneration. Here we examine the process of repair in a relatively simple nervous system, that of the insect, in which it is possible to define (...) precisely the cellular events of the repair process. This repair is rapid and well organised; it involves the recruitment of blood cells, the division of endogenous glial elements and, possibly, migration from pre‐existing glial pools in adjacent ganglia. There are clear parallels between the events of repair and those of normal glial development. It seems likely that the ability of the insect central nervous system to repair resides in the retention of developmental capacities throughout its life and that damage results in the activation of this potential.

The medium surrounding cells either in culture or in tissues contains a chemical mix varying with cell state. As solutes move in and out of the cytoplasmic compartment they set up characteristic signatures in the cellular boundary layers. These layers are complex physical and chemical environments the profiles of which reflect cell physiology and provide conduits for intercellular messaging. Here we review some of the most relevant characteristics of the extracellular/intercellular space. Our initial focus is primarily on cultured cells but (...) we extend our consideration to the far more complex environment of tissues, and discuss how chemical signatures in the boundary layer can or may affect cell function. Critical to the entire essay are the methods used, or being developed, to monitor chemical profiles in the boundary layers. We review recent developments in ultramicro electrochemical sensors and tailored optical reporters suitable for the task in hand. (shrink)

Modeling work by Brian Skyrms and others in recent years has transformed the theoretical role of David Lewis's 1969 model of signaling. The latter can now be understood as a minimal model of communication in all its forms. In this article, we explain how the Lewis model has been generalized, and consider how it and its variants contribute to ongoing debates in several areas. Specifically, we consider connections between the models and four topics: The role of common interest in communication, (...) signaling within the organism, meaning, and the evolution of human communication and language.

These volumes conclude a series initiated in 1974, marking almost fifty years of effort by a huge cohort of scholars. This review is thus a valedictory for the whole series as well as an account of what we have learned from the most recent volumes about Darwin's final years (1879–82). The project was begun by Frederick Burckhardt, who shared the editorial role for the early volumes with Sydney Smith and a rolling sequence of assistant editors and advisers who eventually (...) comprised a significant fraction of the leading members of what used to be called the ‘Darwin industry’. Smith passed away in 1988 (volume 7 notes his legacy). Burkardt too left this world in 2007 – volume 16, part 1 includes an obituary, but his name has been retained and Cambridge University Press still ask that the series be cited as ‘Burkhardt et al.’ Duncan Porter took over for volumes 8–15, again with a sequence of fellow editors and assistants, after which James Secord became head of the project through its final years. The dedications of successive volumes record the efforts of individual scholars who have aided the teams and the involvement of the many institutions and foundations that have leant moral and material support over the years. For those of us with Cambridge connections, the University Library will not seem the same without the presence of the team it supported. (shrink)

This article examines Bentham's contribution to anti-colonial thought in the context of the development of the British radical movement that attacked colonialism on the grounds that it advantaged what Bentham called the at the expense of the . It shows that Bentham was influenced as much by Josiah Tucker and James Anderson as by Adam Smith. Bentham's early economic critique is examined, and the sharp changes in his arguments after 1800 assessed, in the context of the American and French (...) Revolutions and the effects of British industrialization. The article also highlights the importance of Bentham's writings inspired by the Spanish colonial crisis of the early 1820s. They show developments in his economic analysis and include some very acute discussions of the psychological satisfactions that elites could gain from colonialism. The article ends with a brief comparison between Bentham and later radical thinkers to put his ideas in context. (shrink)

This comprehensive and important volume includes contributions by activists, journalists, lawyers and scholars from twenty-one countries. The essays map the directions the movement for women's rights is taking--and will take in the coming decades--and the concomittant transformation of prevailing notions of rights and issues. They address topics such as the rapes in former Yugoslavia and efforts to see that a War Crimes Tribunal responds; domestic violence; trafficking of women into the sex trade; the persecution of lesbians; female genital mutilation; and (...) reproductive rights.

Pancreatitis is a complex, progressively destructive inflammatory disorder. Alcohol was long thought to be the primary causative agent, but genetic contributions have been of interest since the discovery that rare PRSS1, CFTR and SPINK1 variants were associated with pancreatitis risk. We now report two associations at genome-wide significance identified and replicated at PRSS1-PRSS2 and X-linked CLDN2 through a two-stage genome-wide study. The PRSS1 variant likely affects disease susceptibility by altering expression of the primary trypsinogen gene. The CLDN2 risk allele is (...) associated with atypical localization of claudin-2 in pancreatic acinar cells. The homozygous CLDN2 genotype confers the greatest risk, and its alleles interact with alcohol consumption to amplify risk. These results could partially explain the high frequency of alcohol-related pancreatitis in men. © 2012 Nature America, Inc. All rights reserved. (shrink)

Biological ontologies are used to organize, curate, and interpret the vast quantities of data arising from biological experiments. While this works well when using a single ontology, integrating multiple ontologies can be problematic, as they are developed independently, which can lead to incompatibilities. The Open Biological and Biomedical Ontologies Foundry was created to address this by facilitating the development, harmonization, application, and sharing of ontologies, guided by a set of overarching principles. One challenge in reaching these goals was that the (...) OBO principles were not originally encoded in a precise fashion, and interpretation was subjective. Here we show how we have addressed this by formally encoding the OBO principles as operational rules and implementing a suite of automated validation checks and a dashboard for objectively evaluating each ontology’s compliance with each principle. This entailed a substantial effort to curate metadata across all ontologies and to coordinate with individual stakeholders. We have applied these checks across the full OBO suite of ontologies, revealing areas where individual ontologies require changes to conform to our principles. Our work demonstrates how a sizable federated community can be organized and evaluated on objective criteria that help improve overall quality and interoperability, which is vital for the sustenance of the OBO project and towards the overall goals of making data FAIR.

Within the rough ground that is the field of education there is a complex web of ethical obligations: to prepare our students for their future work; to be ethical as educators in our conduct and teaching; to the ethical principles embedded in the contexts in which we work; and given the Southern context of this work, the ethical obligations we have to this land and its First Peoples. We put out a call to colleagues whose work has been concerned with (...) the pedagogies of professional ethics, the ethical burdens of institutional injustice, and the application of ethical theory to education’s applied fields. In the responses we received it can be seen that ethical concerns in education are broad ranging, covering terrain varying from the preparation of preservice teachers, ethics in higher education, early childhood and care, educational leadership, relational and communicative ethics. Perhaps it could also be argued that this paper demonstrates Gibbon’s observation that ‘Assumptions about the particularity of this time as new and ripe with opportunity to make a difference through philosophy of education are not new and there’s much to learn from the persistence of wanting to imagine that they are’. However, while the field of ethics is perennially concerned with human relations and pedagogical interventions to improve these, the responses collected here show that educational ethics is far from static. Educational ethics is a field that continues to develop in response to changing contexts. (shrink)

The Protein Ontology (PRO; http://proconsortium.org) formally defines protein entities and explicitly represents their major forms and interrelations. Protein entities represented in PRO corresponding to single amino acid chains are categorized by level of specificity into family, gene, sequence and modification metaclasses, and there is a separate metaclass for protein complexes. All metaclasses also have organism-specific derivatives. PRO complements established sequence databases such as UniProtKB, and interoperates with other biomedical and biological ontologies such as the Gene Ontology (GO). PRO relates to (...) UniProtKB in that PRO’s organism-specific classes of proteins encoded by a specific gene correspond to entities documented in UniProtKB entries. PRO relates to the GO in that PRO’s representations of organism-specific protein complexes are subclasses of the organism-agnostic protein complex terms in the GO Cellular Component Ontology. The past few years have seen growth and changes to the PRO, as well as new points of access to the data and new applications of PRO in immunology and proteomics. Here we describe some of these developments. (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.

In lieu of an abstract, here is a brief excerpt of the content:Adam Smith and the History of the Invisible HandPeter HarrisonFew phrases in the history of ideas have attracted as much attention as Smith’s “invisible hand,” and there is a large body of secondary literature devoted to it. In spite of this there is no consensus on what Smith might have intended when he used this expression, or on what role it played in Smith’s thought. (...) Estimates of its significance range from the laudatory—“one of the great ideas of history,” to the dismissive—“an ironic joke.”1 Commentators are also divided on whether Smith’s “invisible hand” has teleological or providential connotations, or whether it is simply a rhetorical device. John Kenneth Galbraith declared that we do a grave disservice to Smith if we insist on understanding his invisible hand as a kind of “spiritual force.”2 Spenser J. Pack maintained that the invisible hand was “a rhetorical device which Smith made up, and knew he made up” and certainly “not [End Page 29] a theological underpinning for Smith’s social and/or economic theory.”3 Others have adopted the opposite view. Jacob Viner contended that Smith’s economic theory becomes unintelligible if “the invisible hand” is evacuated of its theological significance.4 For David A. Martin, Smith’s use of the phrase pointed to the foundational role played by divine wisdom in Smith’s thought, while for Andy Denis, “the invisible hand concept in Smith was entirely and unambiguously theological.”5Surprisingly, given this situation, a systematic study of the uses of the expression before Smith has yet to be made.6 Indeed, it is not unusual to find claims that Smith invented the expression himself, or that it was primarily owing to his influence that the phrase first became widespread.7 Those who have made perfunctory efforts at a history of the phrase generally point to a few scattered literary references with a view either to judging them irrelevant to Smith’s oeuvre, or to suggesting that Smith’s (admittedly meagre) uses of the phrase are empty metaphors. This paper seeks to remedy this deficiency, offering a history of “the invisible hand” with a particular focus on the seventeenth and early eighteenth centuries. What clearly emerges from this survey is that the concept was relatively common by the time Smith came to use it. Moreover, while “invisible hand” was used in a variety of contexts, by far the most common involved reference to God’s [End Page 30] oversight of human history and to his control of the operations of nature. Almost certainly, then, when readers encountered the phrase in Smith, they would have understood it as referring to God’s unseen agency in political economy. Whether Smith was himself committed to such a view is more difficult to determine, but the history of the expression and the contexts in which it appears in Smith’s writings offer some support for providentialist readings.Hidden and Invisible HandsThe expression “invisible hand” was not commonly used before the seventeenth century. It does not occur in classical literature (although some have suggested that the phrase may be found in Ovid).8 Neither does it appear in the Hebrew Bible or the New Testament.9 The earliest reference that I have found occurs in a Greek liturgy which invokes God’s “invisible right hand which is full of blessing.”10 The liturgy was used by the Alexandrian Church and its origins date back (probably) to the second century. However, [End Page 31] the expression is relatively rare in subsequent patristic and medieval writings. In one of his Old Testament commentaries, Alexandrian Church father Origen (185–254 ce) attributed the Israelites’ defeat of the Amalekites, recorded in Exodus 17, to the agency of God’s hidden hand.11 Some later sources made reference to the work of a “hidden” or “invisible” hand of God in restoring individuals to health. Augustine of Hippo (354–430 ce) thus spoke of the hidden hand of God which heals and makes whole.12 A medieval source refers similarly to a wound being healed by the touch of an invisible hand.13 French Benedictine Petrus Cellensis (1115–83 ce) alluded to the action...

Recovering Reason: Essays in Honor of Thomas L. Pangle is a collection of essays composed by students and friends of Thomas L. Pangle to honor his seminal work and outstanding guidance in the study of political philosophy. These essays examine both Socrates' and modern political philosophers' attempts to answer the question of the right life for human beings, as those attempts are introduced and elaborated in the work of thinkers from Homer and Thucydides to Nietzsche and Charles Taylor.

David Hume has traditionally been assumed to be a soft determinist or compatibilist, at least in the ‘reconciling project’ that he presents in Section 8 of the first Enquiry, entitled ‘Of liberty and necessity.’ Indeed, in encyclopedias and textbooks of Philosophy he is standardly taken to be one of the paradigm compatibilists, rivalled in significance only by Hobbes within the tradition passed down through Locke, Mill, Schlick and Ayer to recent writers such as Dennett and Frankfurt. Many Hume scholars also (...) concur in viewing him as a determinist, for example Norman Kemp Smith, Barry Stroud, A. J. Ayer, Paul Russell Don Garrett, Terence Penelhum, George Botterill, John Bricke, and John Wright. My main purpose in this paper will be to provide the evidence to substantiate this traditional interpretation, which has hitherto been widely assumed rather than defended. In the absence of such a defence, the consensus has been left open to challenge, most notably in a recent paper and a subsequent book by James Harris, who boldly claims that Hume ‘does not subscribe to determinism of any kind, whether Hobbesian or merely nomological.’.

Diagrams refer to the phenomena overtly represented, to analogous phenomena, and to previous pictures and their graphic conventions. The diagrams of ecologists Clarke, Hutchinson, and H.T. Odum reveal their search for physical analogies, building on the success of World War II science and the promise of cybernetics. H.T. Odum's energy circuit diagrams reveal also his aspirations for a universal and natural means of reducing complexity to guide the management of diverse ecological and social systems. Graphic conventions concerning framing and translation (...) of ecological processes onto the flat printed page facilitate Odum's ability to act as if ecological relations were decomposable into systems and could be managed by analysts external to the system.

Impossible Presence brings together new work in film studies, critical theory, art history, and anthropology for a multifaceted exploration of the continuing proliferation of visual images in the modern era. It also asks what this proliferation—and the changing technologies that support it—mean for the ways in which images are read today and how they communicate with viewers and spectators. Framed by Terry Smith's introduction, the essays focus on two kinds of strangeness involved in experiencing visual images in the modern (...) era. The first, explored in the book's first half, involves the appearance of oddities or phantasmagoria in early photographs and cinema. The second type of strangeness involves art from marginalized groups and indigenous peoples, and the communicative formations that result from the trafficking of images between people from vastly different cultures. With a stellar list of contributors, Impossible Presence offers a wide-ranging look at the fate of the visual image in modernity, modern art, and popular culture.

SummaryE. W. MacBride was one of the last supporters of Lamarckian evolution, and played a prominent role in the ‘case of the midwife toad’. Unlike most Lamarckians, however, he adopted a very conservative political stance, advocating the permanent inferiority of some races and the necessity of restricting the breeding of the unfit. This article shows how MacBride turned Lamarckism into a plausible means of supporting these positions, by arguing that progressive evolution is a slow process, and that degeneration of the (...) germ plasm takes place in unfavourable environments. In conclusion, it is suggested that MacBride's example shows that there are no intrinsic links between scientific theories and social views. These who insist on the social character of scientific knowledge must recognize that a theory may acquire different ideological links in different social environments. (shrink)
