The efficiency of engineering applied to civilian projects sometimes threatens to run away with the social agenda, but in military applications, engineering often adds a devastating sleekness to the inevitable destruction of life. The relative crudeness of terrorism (e.g., 9/11) leaves a stark after-image, which belies the comparative insignificance of random (as opposed to orchestrated) belligerence. Just as engineering dwarfs the bricolage of vernacular design—moving us past the appreciation of brush-strokes, so to speak—the scale of engineered destruction makes it difficult (...) to focus on the charred remains of individual lives. Engineers need to guard against the inappropriate military subsumption of their effort. Fortunately, the ethics of warfare has been an ongoing topic of discussion for millennia. This paper will examine the university core class I’ve developed (The Moral Dimensions of Technology) to meet accreditation requirements in engineering ethics, and the discussion with engineering and non-engineering students focused by the life of electrical engineer Vannevar Bush, with selected readings in moral philosophy from the Dao de Jing, Lao Tze, Cicero, Aurelius Augustinus, Kant, Annette Baier, Peter Singer, Elizabeth Anscombe, Philippa Foot, and Judith Thomson.

Our shared moral framework is negotiated as part of the social contract. Some elements of that framework are established (tell the truth under oath), but other elements lack an overlapping consensus (just when can an individual lie to protect his or her privacy?). The tidy bits of our accepted moral framework have been codified, becoming the subject of legal rather than ethical consideration. Those elements remaining in the realm of ethics seem fragmented and inconsistent. Yet, our engineering students will need (...) to navigate the broken ground of this complex moral landscape. A minimalist approach would leave our students with formulated dogma—principles of right and wrong such as the National Society for Professional Engineers (NSPE) Code of Ethics for Engineers—but without any insight into the genesis of these principles. A slightly deeper, micro-ethics approach would teach our students to solve ethical problems by applying heuristics—giving our students a rational process to manipulate ethical dilemmas using the same principles simply referenced a priori by dogma. A macro-ethics approach—helping students to inductively construct a posteriori principles from case studies—goes beyond the simple statement or manipulation of principles, but falls short of linking personal moral principles to the larger, social context. Ultimately, it is this social context that requires both the application of ethical principles, and the negotiation of moral values—from an understanding of meta-ethics. (shrink)

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)

Larry Hardin has been the most steadfast and influential critic of physicalist theories of color over the last 20 years. In their modern form these theories originated with the work of Smart and Armstrong in the 1960s and 1970s1 and Hardin appropriately concentrated on their views in his initial critique of physicalism.2 In his most recent contribution to this project3 he attacks Michael Tye’s recent attempts to defend and extend color physicalism.4 Like Byrne and Hilbert5, Tye identifies color with the (...) reflecting properties of objects (“reflectance physicalism”). Specifically, the determinate and determinable colors are identified with types of reflectances. (Setting some complications aside, the reflectance of an object is the proportion of light that it reflects at each wavelength in the visible spectrum.) These reflectance types are, in the terminology of Hilbert, anthropocentric—in the terminology of Lewis6, they are not very “natural”. (shrink)

Written by some of the world's leading academics and professionals in the field, this collection of essays brings together two complementary views on child development - the role of society and the role of cognitive growth.

Previous research suggests that early performance of amnesic individuals in a probabilistic category learning task is relatively unimpaired. When combined with impaired declarative knowledge, this is taken as evidence for the existence of separate implicit and explicit memory systems. The present study contains a more fine-grained analysis of learning than earlier studies. Using a dynamic lens model approach with plausible learning models, we found that the learning process is indeed indistinguishable between an amnesic and control group. However, in contrast to (...) earlier findings, we found that explicit knowledge of the task structure is also good in both the amnesic and the control group. This is inconsistent with a crucial prediction from the multiple-systems account. The results can be explained from a single system account and previously found differences in later categorization performance can be accounted for by a difference in learning rate. (shrink)

Throughout his life J. J. Thomson was committed to a mechanical interpretation of nature. This work proceeded in several stages. Early in his career he attempted a Lagrangian formulation of mechanics. But due to certain epistemological difficulties with this approach, he began exploring various analogies and models, particularly those involving vortex motion. After his discovery of the electron in 1897, he commenced a synthesis of the electron with his previous physical conceptions. The result was a hypothesis of the ether as (...) being composed of particles even smaller than electrons. (shrink)

Although the importance of literacy is widely acknowledged in society and remains at the top of the political agenda, writing has been slow to establish a place in the cognitive sciences. Olson argues that to understand the cognitive implications of literacy, it is necessary to see reading and writing as providing access to and consciousness of aspects of language, such as phonemes, words and sentences, that are implicit and unconscious in speech. Reading and writing create a system of metarepresentational concepts (...) that bring those features of language into consciousness as a subject of discourse. This consciousness of language is essential not only to acquiring literacy but also to the formation of systematic thought and rationality. The Mind on Paper is a compelling exploration of what literacy does for our speech and hence for our thought, and will be of interest to readers in developmental psychology, cognitive science, linguistics, and education.

Solar radiation management (SRM), a form of climate engineering, would offset the effects of increased greenhouse gas concentrations by reducing the amount of sunlight absorbed by the Earth. To encourage support for SRM research, advocates argue that SRM may someday be needed to reduce the risks from climate change. This paper examines the implications of two moral constraints—the Doctrine of Doing and Allowing, and the Doctrine of Double Effect—on this argument for SRM and SRM research. The Doctrine of Doing and (...) Allowing, and perhaps the Doctrine of Double Effect, shows that the argument is weaker than it appears. (shrink)

Over the past decade or so, several commentators have called for mission-driven research programs on solar geoengineering, also known as solar radiation management (SRM) or climate engineering. Building on the largely epistemic reasons offered by earlier commentators, this paper argues that a well-designed mission-driven research program that aims to evaluate solar geoengineering could promote justice and legitimacy, among other valuable ends. Specifically, an international, mission-driven research program that aims to produce knowledge to enable well-informed decision-making about solar geoengineering could (1) (...) provide a more effective way to identify and answer the questions that policymakers would need to answer; and (2) provide a venue for more efficient, effective, just, and legitimate governance of solar geoengineering research; while (3) reducing the tendency for solar geoengineering research to exacerbate international domination. Thus, despite some risks and limitations, a well-designed mission-driven research program offers one way to improve the governance of solar geoengineering research relative to the ‘investigator-driven’ status quo.

Colour has often been supposed to be a subjective property, a property to be analysed orretly in terms of the phenomenological aspects of human expereince. In contrast with subjectivism, an objectivist analysis of color takes color to be a property objects possess in themselves, independently of the character of human perceptual expereince. David Hilbert defends a form of objectivism that identifies color with a physical property of surfaces - their spectral reflectance. This analysis of color is shown to provide (...) a more adequate account of the features of human color vision than its subjectivist rivals. The author's account of colro also recognises that the human perceptual system provides a limited and idiosyncratic picture of the world. These limitations are shown to be consistent with a realist account of colour and to provide the necessary tools for giving an analysis of common sense knowledge of color phenomena. (shrink)

It is human nature to wonder how things might have turned out differently--either for the better or for the worse. For the past two decades psychologists have been intrigued by this phenomenon, which they call counterfactual thinking. Specifically, researchers have sought to answer the "big" questions: Why do people have such a strong propensity to generate counterfactuals, and what functions does counterfactual thinking serve? What are the determinants of counterfactual thinking, and what are its adaptive and psychological consequences? This important (...) work brings together a collection of thought-provoking papers by social and cognitive psychologists who have made important theoretical and empirical contributions to our understanding of this topic. The essays in this volume contain novel theoretical insights, and, in many cases descriptions of previously unpublished empirical studies. The Psychology of Counterfactual Thinking provides an excellent overview of this fascinating topic for researchers, as well as advanced undergraduates and graduates in psychology--particularly those with an interest in social cognition, social judgment, decision judgment, decision making, thinking and reasoning.

Multiple cue probability learning studies have typically focused on stationary environments. We present three experiments investigating learning in changing environments. A fine-grained analysis of the learning dynamics shows that participants were responsive to both abrupt and gradual changes in cue-outcome relations. We found no evidence that participants adapted to these types of change in qualitatively different ways. Also, in contrast to earlier claims that these tasks are learned implicitly, participants showed good insight into what they learned. By fitting formal learning (...) models, we investigated whether participants learned global functional relationships or made localized predictions from similar experienced exemplars. Both a local (the Associative Learning Model) and a global learning model (the novel Bayesian Linear Filter) fitted the data of the first two experiments. However, the results of Experiment 3, which was specifically designed to discriminate between local and global learning models, provided more support for global learning models. Finally, we present a novel model to account for the cue competition effects found in previous research and displayed by some of our participants. (shrink)

One central question of climate justice is how to fairly allocate the global emissions budget. Some commentators hold that the concept of fairness is hopelessly equivocal on this point. Others claim that we need a complete theory of distributive justice to answer the question. This paper argues to the contrary that, given only weak assumptions about fairness, we can show that fairness requires an allocation that is at least as prioritarian as the equal per capita view. Since even the equal (...) per capita view is more prioritarian than is politically feasible, fairness is univocal enough for all practical purposes. (shrink)

Time pressure has been shown to have a negative impact on ethical decision-making. This paper uses an experimental approach to examine the impact of an antecedent of time pressure, whether it is anticipated or not, on participants’ perceptions of unethical behaviour. Utilising 60 business school students at an Australian university, we examine the differential impact of anticipated and unanticipated time deadline pressure on participants’ perceptions of the likelihood of unethical behaviour occurring. We find the perception of the likelihood of unethical (...) behaviour occurring to be significantly reduced when time pressure is anticipated rather than unanticipated. The implications of this finding for both professional service organisations and tertiary institutions are considered. (shrink)

Dimorphism in the yeast Candida albicans provides an unusually simple model system for investigating the mechanisms which regulate cellular differentiation, or cell divergence. Under the regime of pH‐regulated dimorphism, it has been demonstrated that the programs of protein synthesis accompanying bud and hypha formation are strikingly similar. Instead of dramatic differences in the repertoire of gene products possessed by bud‐ and hypha‐forming cells, subtle temporal, spatial and quantitative differences in the same architectural events appear to be basic to the genesis (...) of alternative phenotypes. This emerging story of phenotypic regulation does not exclude differential gene expression, but rather de‐emphasizes its role and underscores other mechanisms which are not generally considered.

This article reprints the text of a review of adam smith's "theory of moral sentiments", And presents arguments for ascribing it to david hume. Hume's subsequent criticism of what he called "the hinge" of adam smith's moral system ("viz." that "all kinds of sympathy are necessarily agreeable") is also examined, And it is argued that smith failed to appreciate the nature and extent of this criticism. It is concluded that "the hinge" of smith's novel theory is a false assumption; (...) yet without it smith cannot present a viable alternative to hume's explanation of the origin of our moral sentiments.

It is widely accepted that global forces of technology and trade have caused a profound shift in labor demand toward the most highly skilled, generating sharply rising earnings inequality in flexible labor markets and persistently high unemployment in rigid labor markets. This article critically assesses the evidence for this “Unified Theory.” It finds little compelling empirical support for either the skill-biased demand-shift explanation for high U.S. earnings inequality or the rigid labor markets explanation for high unemployment in Europe. This assessment (...) challenges the policy orthodoxy of the 1990s that developed economies feature a strict inequality-unemployment trade-off and that policy options are therefore limited to skills enhancement in the United States and labor market deregulation in Europe. It is suggested that the theoretical dominance of the textbook supply/demand model has contributed to the neglect of labor market institutions for U.S. wage outcomes and tight macroeconomic policy for European unemployment.

This paper proposes a new organizational metaphor, the ‘Biophilic Organization’, which aims to counter the bio-cultural disconnection of many organizations despite their espoused commitment to sustainability. This conceptual research draws on multiple disciplines such as evolutionary psychology and architecture to not only develop a diverse bio-cultural connection but to show how this connection tackles sustainability, in a holistic and systemic sense. Moreover, the paper takes an integrative view of sustainability, which effectively means that it embraces the different emergent tensions. Three (...) specific tensions are explored: efficiency versus resilience, organizational versus personal agendas and isomorphism versus institutional change. In order to illustrate how the Biophilic Organization could potentially provide a synthesis strategy for such tensions, healthcare examples are drawn from the emerging fields of Biophilic Design in Singapore and Generative Design in the U.S.A. Finally, an example is provided which highlights how a Taoist cultural context has impacted on a business leader in China, to illustrative the significance of a transcendent belief system to such a bio-cultural narrative.

An in-depth study of Kierkegaard's thinking on Christology, emphasising the radical nature of his approach to the incarnation, with an emphasis on the call of the Christian believer to a life of 'kenotic' (self-emptying) discipleship in imitation of Christ.

Many commentators fear that climate engineering research might lead policy-makers to reduce mitigation efforts. Most of the literature on this so-called ‘moral hazard’ problem focuses on the prediction that climate engineering research would reduce mitigation efforts. This paper focuses on a related ethical question: Why would it be a bad thing if climate engineering research obstructed mitigation? If climate engineering promises to be effective enough, it might justify some reduction in mitigation. Climate policy portfolios involving sufficiently large or poorly planned (...) reductions in mitigation, however, could lead to an outcome that would be worse than the portfolio that would be chosen in the absence of further climate engineering research. This paper applies three ethical perspectives to describe the kinds of portfolios that would be worse than that ‘baseline portfolio’. The literature on climate engineering identifies various mechanisms that might cause policy-makers to choose these inferior portfolios, but it is difficult to know in advance whether the existence of these mechanisms means that climate engineering research really would lead to a worse outcome. In the light of that uncertainty, a precautionary approach suggests that researchers should take measures to reduce the risk of mitigation obstruction. Several such measures are suggested. (shrink)

The final lines of Deleuze and Guattari’s What is Philosophy? call for a non-philosophy to balance and act as a counterweight to the task of philosophy that had been described by them in terms of concept creation. In a footnote, Deleuze and Guattari mention François Laruelle’s project of non-philosophy, but dispute its efficacy in terms of the designated relationship between non-philosophy and science, as had been realised by Laruelle at the time. However, the mature non-philosophy of Laruelle could indicate a (...) resolution to the problematic relationship between science and educational philosophy that we have inherited due to the poststructural theories of Foucault, Derrida and Deleuze. Non-philosophy suggests a framework for thought that includes science in a non-positivist style and provides the means to view education as a performative practice. This article explores the non-philosophy of Laruelle in education as a means to view education under the conditions of strict immanence and in line with an anti-phenomenological metaphysics of non-representation. Laruelle is perhaps one of the most important critics of Deleuze in France, and as such, his insights into the Deleuzian oeuvre reveal a way forward for education as a practice that analyses science, philosophy and politics through non-philosophy.
