Abstractftz is one of the ‘pair rule’ segmentation genes of Drosophila melanogaster, and is an important component of the segmentation process in the fruit fly. We discuss the transcriptional mechanism which causes ftz to be expressed in a seven stripe pattern during embryogenesis.

ExcerptCarl Schmitt (1888–1985) is known as the most consequential German legal and political mind of the twentieth century.1 Many crimes of the Nazi regime found support in his conceptual justifications, and Schmitt is called the “Crown Jurist” of the Third Reich with good reason. Historians, political scientists, and sociologists must grapple with the author in order to understand the course of totalitarianism in modernity. Whether literary historians should do so is far less settled, though he was fascinated by their object (...) of study. His writings on literary topics are said to reveal much about Schmitt’s person, politics, and period, but little about literature itself.2 This explains why his “Don Quijote und das Publikum” (“Don Quixote and the Public”), published in the arts and cultural journal Die Rheinlande in 1912, was almost unknown in literary studies for a century.3 Schmitt’s text on the novel by Miguel de Cervantes has not been reprinted, and until recently it had not been translated from the original German. Size has a role too. At under two thousand words, the text has probably escaped notice due to its small scale.4 Recent English and Italian translations in major humanistic journals may signal the end of its obscurity though.5 “Don Quixote and the Public” is at the door of literary studies. The question now is not whether to respond, but how. (shrink)

At least seven orphan members of the nuclear receptor superfamily are transcriptionally regulated by the steroid hormone ecdysone and expressed during the onset of Drosophila metamorphosis. A recent paper provides functions for two of these receptors, E75B and DHR3, through trans‐regulation and heterodimerization(1). DHR3 appears to function as a switch that defines the transition from a late larva to a prepupa, and E75B functions as a timer that modulates this transition. This study provides a biological function for orphan receptor interactions (...) during development. (shrink)

Sixteen years ago, Michael Ashburner and his colleagues proposed a hierarchical model for the genetic control of polytene chromosome puffing by the steroid hormone ecdysone. The recent molecular isolation and characterization of three early ecdysone‐inducible genes has confirmed many aspects of this model — these genes are directly induced by ecdysone, repressed by ecdysone‐induced proteins, and appear to encode DNA binding regulatory proteins. The three early genes are also remarkably similar in structure. They are all unusually long and complex, with (...) multiple transcripts that direct the synthesis of several related proteins from each locus. Proteins encoded by two of the early genes bind to both early and late ecdysone‐induced puffs, implying that they are key regulators in the hierarchy. (shrink)

Programmed cell death is a critical part of normal development, removing obsolete tissues or cells and sculpting body parts to assume their appropriate form and function. Most programmed cell death occurs by apoptosis of individual cells or autophagy of groups of cells. Although these pathways have distinct morphological characteristics, they also have a number of features in common, suggesting some overlap in their regulation. A recent paper by Lee and Baehrecke provides further support for this proposal.(1) These authors present, for (...) the first time, a genetic analysis of autophagy, using the steroid‐triggered metamorphosis of Drosophila as a model system. They demonstrate a remarkable degree of overlap between the control of apoptosis and autophagy as well as a key role for the steroid‐inducible gene E93 in directing the autophagic death response. This paper also shows that E93 can direct cell death independently from the known death‐inducer genes, defining a novel death pathway in Drosophila.

This paper suggests an alternative reading of Practice in Christianity to Merold Westphal’s interpretation of the text as defining what he calls “religiousness C.” Attending closely to the rhetorical construction of Practice, and situating it in the context of Kierkegaard’s intensive reading of Luther late in his life, I argue that this text extends the Postscript’s meditation on inwardness and writing to one of the central theological constructs of Lutheranism, the distinction between law and gospel. On my reading, Practice both (...) defends the primacy of faith and grace within Christianity, and refuses their commodification into directly communicable results. At the end of this paper, I consider Kierkegaard’s seeming retraction, in 1855, of two rhetorical features of Practice that my reading emphasizes. Iconclude that this gesture in fact intensifies Kierkegaard’s appropriation of the law/gospel paradigm, and speaks to the impossibility of any direct, comprehensive, and final account of authentic Christian life.

Ursula Coope's volume sets out to answer the question of why "true freedom" necessitates "freedom from bodies" according to the Neoplatonists. As a result, while the title suggests a work on ethics, the volume handles such questions within a broader metaphysical framework. Coope admirably traces the initially separate treatments of freedom and responsibility in earlier thinkers before examining how they merge into twin aspects of a related discussion. The handling of Plato's concept of freedom in the first chapter outlines a (...) series of relevant issues, rather than evaluating their relative significance, since the primary focus is on the subsequent tradition. The title is somewhat misleading since much of the... (shrink)

Thermodynamics is the foundation of many of the topics of interest in the religion‐science dialogue. Here a nonmathematical outline of the principles of thermodynamics is presented, providing a historical and conceptually understandable development that can serve teachers from disciplines other than physics. The contributions of Gibbs to both classical and rational thermodynamics, emphasizing the importance of the ensemble in statistical mechanics, are discussed. The seminal ideas of Boltzmann on statistical mechanics are contrasted to those of Gibbs in a discussion of (...) the microscopic interpretation of the second law. The role of information theory is discussed, and the modern ideas of Prigogine and nonequilibrium are outlined in some detail with further reference to the second law. Implications for our interaction with God are considered. (shrink)

The quantum‐measurement problem and the Heisenberg indeterminacy principle are presented in the language of the Dirac formulation of the quantum theory. Particularly the relationship between quantum state prior to measurement and the result of the measurement are discussed. The relation between the indeterminacy principle and the analog between quantum and classical systems is presented, showing that this principle may be discussed independently of the wave‐particle duality. The importance of statistics in the treatment of many body systems is outlined and the (...) approach to investigating God's interaction with human beings is discussed in this context. The treatment is nonmathematical. (shrink)

Abstract.The basic laws of physics for particles and fields can be formulated in terms of variational principles. The initial development of a variational principle had distinct teleological implications. The formulation of physical laws in terms of variational principles is outlined with specific reference to classical and quantum mechanics and field theory. Because of time irreversibility no variational principle exists for thermodynamics. In order to obtain time irreversibility molecular trajectories must be abandoned in the lowest‐level description of complex multicomponent systems. A (...) more open set of possibilities results. I suggest that this may be more consistent with a modern teleology. (shrink)

John Polkinghorne is a significant contributor to the religion and science dialogue, bringing the expertise of a scientist coupled with serious theological study, ordination, and service as a parish priest. He takes both theology and science with utmost seriousness and describes himself as a bottom‐up thinker, confronting the scriptural record as a scientist does data. But he refrains from giving scientific explanations of scripture. Polkinghorne's concern is with hope, and specifically with eschatological hope. The framework for his theological thinking is (...) the Nicene Creed, in which is found the counterintuitive openness common to theoretical physics. He acknowledges the need for thinking beyond the confines of present scientific understanding in proposing active information as a concept for considering the mind. (shrink)

Lloyd (2009) contends that climate models are confirmed by various instances of fit between their output and observational data. The present paper argues that what these instances of fit might confirm are not climate models themselves, but rather hypotheses about the adequacy of climate models for particular purposes. This required shift in thinking—from confirming climate models to confirming their adequacy-for-purpose—may sound trivial, but it is shown to complicate the evaluation of climate models considerably, both in principle and in practice.

Recently, the outsourcing of Information Technology activities to offshore locations has been gaining significant momentum, with some associated backlash by the workforce in the United States. Based on their 2005 survey [6], Global Insight, a private consulting firm, estimated that U.S. companies will spend about $38.2 billion in offshore IT services by 2010, compared with about $15.2 billion in 2005, primarily because the expected cost savings will grow by $11.7 billion in the same time period. Binder writing in "Foreign Affairs" (...) [2] states that offshoring expenditures will continue to increase dramatically, and the changes the offshoring phenomenon will bring will transform society. This paper focuses on the social impact of offshoring and the effects of the weighing of costs and benefits as a result of offshoring activities. (shrink)

To study Earth’s climate, scientists now use a variety of computer simulation models. These models disagree in some of their assumptions about the climate system, yet they are used together as complementary resources for investigating future climatic change. This paper examines and defends this use of incompatible models. I argue that climate model pluralism results both from uncertainty concerning how to best represent the climate system and from difficulties faced in evaluating the relative merits of complex models. I describe how (...) incompatible climate models are used together in ‘multi-model ensembles’ and explain why this practice is reasonable, given scientists’ inability to identify a ‘best’ model for predicting future climate. Finally, I characterize climate model pluralism as involving both an ontic competitive pluralism and a pragmatic integrative pluralism. (shrink)

Philosophers continue to debate both the actual and the ideal roles of values in science. Recently, Eric Winsberg has offered a novel, model-based challenge to those who argue that the internal workings of science can and should be kept free from the influence of social values. He contends that model-based assignments of probability to hypotheses about future climate change are unavoidably influenced by social values. I raise two objections to Winsberg’s argument, neither of which can wholly undermine its conclusion but (...) each of which suggests that his argument exaggerates the influence of social values on estimates of uncertainty in climate prediction. I then show how a more traditional challenge to the value-free ideal seems tailor-made for the climate context. (shrink)

Recent work has defended “Euclidean” theories of set size, in which Cantor’s Principle (two sets have equally many elements if and only if there is a one-to-one correspondence between them) is abandoned in favor of the Part-Whole Principle (if A is a proper subset of B then A is smaller than B). It has also been suggested that Gödel’s argument for the unique correctness of Cantor’s Principle is inadequate. Here we see from simple examples, not that Euclidean theories of set (...) size are wrong, but that they must be either very weak and narrow or largely arbitrary and misleading. (shrink)

This paper provides a systematic account of how artificial intelligence (AI) technologies could harm nonhuman animals and explains why animal harms, often neglected in AI ethics, should be better recognised. After giving reasons for caring about animals and outlining the nature of animal harm, interests, and wellbeing, the paper develops a comprehensive ‘harms framework’ which draws on scientist David Fraser’s influential mapping of human activities that impact on sentient animals. The harms framework is fleshed out with examples inspired by both (...) scholarly literature and media reports. This systematic account and framework should help inform ethical analyses of AI’s impact on animals and serve as a comprehensive and clear basis for the development and regulation of AI technologies to prevent and mitigate harm to nonhumans.

Extracorporeal membrane oxygenation (ECMO) is a form of life support for cardiac and/or pulmonary failure with unique ethical challenges compared to other forms of life support. Ethical challenges with ECMO exist when conventional standards of care apply, and are exacerbated during periods of absolute ECMO scarcity when “crisis standards of care” are instituted. When conventional standards of care apply, we propose that it is ethically permissible to withhold placing patients on ECMO for reasons of technical futility or when patients have (...) terminal, short-term prognoses that are untreatable by ECMO. Under crisis standards of care, it is ethically permissible to broaden exclusionary criteria to also withhold ECMO from patients who have a low likelihood of recovery, to maximize the overall number of lives saved. Unilateral withdrawal of ECMO against a patient’s preferences is unethical under conventional standards of care, but is ethical under crisis standards of care to increase access to ECMO to others in society. ECMO should only be rationed when true scarcity exists, and allocation protocols should be transparent to the public. When rationing must occur under crisis standards of care, it is imperative that oversight bodies assess for inequities in the allocation of ECMO and make frequent changes to improve any inequities.

In order to involve children in the decision-making process about participation in medical research it is widely recommended that the child’s assent be sought in addition to parental consent. However, the concept of assent is fraught with difficulties, resulting in confusion among researchers and ethics committees alike.

In this paper I argue that junior doctors are morally exploited. Moral exploitation occurs where an individual’s vulnerability is used to compel them to take on additional moral burdens. These might include additional moral responsibility, making weighty moral decisions and shouldering the consequent emotions. Key to the concept of exploitation is vulnerability and here I build on Rosalind McDougall’s work on the key roles of junior doctors to show how these leave them open to moral exploitation by restricting their reasonable (...) options. I argue that there are a number of ways junior doctors are morally exploited. First, their seniors can leverage their position to force a junior to take on some discreet decision. More common is the second type of moral exploitation where rota gaps and staffing issues means junior doctors take on more than their fair share of the moral burdens of practice. Third, I discuss structural moral exploitation where the system offloads moral burdens onto healthcare professionals. Not every instance of exploitation is wrongful and so I conclude by exploring the ways that moral exploitation wrongs junior doctors. (shrink)

This article explores some of the roles of computer simulation in measurement. A model-based view of measurement is adopted and three types of measurement—direct, derived, and complex—are distinguished. It is argued that while computer simulations on their own are not measurement processes, in principle they can be embedded in direct, derived, and complex measurement practices in such a way that simulation results constitute measurement outcomes. Atmospheric data assimilation is then considered as a case study. This practice, which involves combining information (...) from conventional observations and simulation-based forecasts, is characterized as a complex measuring practice that is still under development. The case study reveals challenges that are likely to resurface in other measuring practices that embed computer simulation. It is also noted that some practices that embed simulation are difficult to classify; they suggest a fuzzy boundary between measurement and non-measurement. 1 Introduction2 A Contemporary View of Measurement3 Three Types of Measurement4 Can Computer Simulations Measure Real-World Target Systems?5 Case Study: Atmospheric Data Assimilation5.1 Why data assimilation?5.2 A complex measuring practice under development5.3 Epistemic iteration6 The Boundaries of Measurement7 Epistemology, Not Terminology.

We call attention to an underappreciated way in which non-epistemic values influence evidence evaluation in science. Our argument draws upon some well-known features of scientific modeling. We show that, when scientific models stand in for background knowledge in Bayesian and other probabilistic methods for evidence evaluation, conclusions can be influenced by the non-epistemic values that shaped the setting of priorities in model development. Moreover, it is often infeasible to correct for this influence. We further suggest that, while this value influence (...) is not particularly prone to the problem of wishful thinking, it could have problematic non-epistemic consequences in some cases. (shrink)

This paper presents a computational model that integrates a dynamically structured holographic memory system into the ACT-R cognitive architecture to explain how linguistic representations are encoded and accessed in memory. ACT-R currently serves as the most precise expression of the moment-by-moment working memory retrievals that support sentence comprehension. The ACT-R model of sentence comprehension is able to capture a range of linguistic phenomena, but there are cases where the model makes the wrong predictions, such as the over-prediction of retrieval interference (...) effects during sentence comprehension. Here, we investigate one such case involving the processing of sentences with negative polarity items and consider how a dynamically structured holographic memory system might provide a cognitively plausible and principled explanation of some previously unexplained effects. Specifically, we show that by replacing ACT-R's declarative memory with a dynamically structured memory, we can explain a wider range of behavioral data involving reading times and judgments of grammaticality. We show that our integrated model provides a better fit to human error rates and response latencies than the original ACT-R model. These results provide proof-of-concept for the unification of two independent computational cognitive frameworks. (shrink)

Relativism in psychology unravels the truth-claims and oppressive\npractices of the discipline, but simply relativizing psychological knowledge\nhas not been sufficient to comprehend and combat the discipline\nas part of the ‘psy-complex’. For that, a balanced review of the contribution\nand problems of relativism needs to work dialectically, and so\nthis article reviews four problematic rhetorical balancing strategies in\nrelativism before turning to the contribution of critical realism. Critical\nrealism exposes positivist psychology’s pretensions to model itself\non what it imagines the natural sciences to be, and it grounds (...) discursive\naccounts of mentation in social practices. The problem is that those\nsympathetic to mainstream psychology are also appealing to ‘realism’\nto warrant it as a science and to discredit critical research that situates\npsychological phenomena. Our use of critical realism calls for an\naccount of how psychological facts are socially constructed within\npresent social arrangements and for an analysis of the underlying historical\nconditions that gave rise to the ‘psy-complex’. Only by understanding\nhow the discipline of psychology reproduces notions of\nindividuality and human nature, a critical realist endeavour, will it be\npossible to transform it, and to socially construct it as something different.

Ethical discussions about Artificial Intelligence (AI) often overlook its potentially large impact on nonhuman animals. In a recent commentary on our paper about AI’s possible harms, Leonie Bossert argues for a focus not just on the possible negative impacts but also the possible beneficial outcomes of AI for animals. We welcome this call to increase awareness of AI that helps animals: developing and using AI to improve animal wellbeing and promote positive dimensions in animal lives should be a vital ethical (...) goal. Nonetheless, we argue that there is some value in focusing on technology-based harms in the context of AI ethics and policy discourses. A harms framework for AI can inform some of our strongest duties to animals and inform regulation and risk assessment impacts designed to prevent serious harms to humans, the environment, and animals.

Drawing on select works of Adorno, we will first rehearse his reasons for a rejuvenation of philosophy and apply them to philosophers working on world philosophical traditions. We will then analyse Adorno’s arguments pertaining to the theory–praxis relation to ascertain whether his thought could accommodate a study of world philosophical traditions for the simple reason that they are present in a particular society. Shifting our focus slightly, we reflect upon how current ways of professional philosophizing affect the study of world (...) philosophical traditions. As the example of Māori philosophy demonstrates, current philosophical practices seem to delimit the search for the unconventional in academic philosophy. Through its philosophical appropriation, the so-called unconventional tends to mimic conventional patterns in academic philosophy. We will then attempt to find reasons to critique this process within the Adornoian framework itself. The conclusion draws together different strands of the discussion and delineates some paths to take forward the world philosophies project in an Adornoian spirit. (shrink)

Organizational change surrounding the security of identifiable health information has become imperative. This is a significant challenge for managers who are held responsible for loss of privacy through faulty security procedures. Management cannot completely secure the organization and still provide employees and customers with the information and services they need. Organizations must decide how much and what type of security they need, how to assign priorities, and how to manage security as the organization evolves in a competitive environment.
