Peoples’ perceptions of healthy eating are influenced by the cultural context in which they occur. Despite this general acceptance by health practitioners and social scientists, studies suggest that there remains a relative homogeneity around peoples’ perceptions that informs a hegemonic discourse around healthy eating. People often describe healthy eating in terms of learned information from sources that reflect societies’ norms and values, such as the Canada Food Guide and the ubiquitous phrase “fruits and vegetables”. Past research has examined how built (...) environments shape people’s access to healthy living options, such as distribution of grocers versus convenience stores and fast food restaurants. Often overlooked is an in-depth understanding of how social contexts interact with built environments, molding peoples’ perceptions of healthy eating. This paper reports on perceptions of healthy eating in four communities across Alberta, Canada. A photovoice methodology was employed to elicit perceptions of healthy eating with 35 participants. This study illustrates how participants’ photographs and their stories convey multiple meanings about healthy eating within their own lives and communities. Findings suggest that a ‘local’ context is an important part of the discourse centered around the promotion of healthy eating practices in these and potential other communities. (shrink)

Wilhelm Bousset, a leading member of the religionsgeschichtliche school and author of a seminal work on early Christology, Kyrios Christos, is typically regarded by reviewers of his work as a classic nineteenth-century liberal who sought a secure foundation for faith in the historical Jesus. However, this view of Bousset fails to appreciate the significant development of his theological perspective on the relationship between faith and history, a perspective that underwent a profound shift due to the influence of the English historian (...) Thomas Carlyle and the Kantian philosopher Jakob Friedrich Fries. It is the influence of these two figures that enables Bousset to justify a full-scale flight from history and to seek faith's foundation elsewhere, in the poetic symbol of Jesus Christ. The resulting solution to the problem of faith and history represents a unique and compelling alternative to the solutions of the leading theologians and New Testament scholars of the early twentieth century.

Doubly robust (DR) estimators are an important class of statistics derived from a theory of semiparametric efficiency. They have become a popular tool in causal inference, including applications to dynamic treatment regimes. The doubly robust estimators for the mean response to a dynamic treatment regime may be conceived through the augmented inverse probability weighted (AIPW) estimating function, defined as the sum of the inverse probability weighted (IPW) estimating function and an augmentation term. The IPW estimating function of the causal estimand (...) via marginal structural model is defined as the complete-case score function for those subjects whose treatment sequence is consistent with the dynamic regime in question divided by the probability of observing the treatment sequence given the subject's treatment and covariate histories. The augmentation term is derived by projecting the IPW estimating function onto the nuisance tangent space and has mean-zero under the truth. The IPW estimator of the causal estimand is consistent if (i) the treatment assignment mechanism is correctly modeled and the AIPW estimator is consistent if either (i) is true or (ii) nested functions of intermediate and final outcomes are correctly modeled.Hence, the AIPW estimator is doubly robust and, moreover, the AIPW is semiparametric efficient if both (i) and (ii) are true simultaneously. Unfortunately, DR estimators can be inferior when either (i) or (ii) is true and the other false. In this case, the misspecified parts of the model can have a detrimental effect on the variance of the DR estimator. We propose an improved DR estimator of causal estimand in dynamic treatment regimes through a technique originally developed by [4] which aims to mitigate the ill-effects of model misspecification through a constrained optimization.In addition to solving a doubly robust system of equations, the improved DR estimator simultaneously minimizes the asymptotic variance of the estimator under a correctly specified treatment assignment mechanism but misspecification of intermediate and final outcome models. We illustrate the desirable operating characteristics of the estimator through Monte Carlo studies and apply the methods to data from a randomized study of integrilin therapy for patients undergoing coronary stent implantation. The methods proposed here are new and may be used to further improve personalized medicine, in general. (shrink)

By combining and augmenting recent arguments that have appeared in the literature, I show how a modified Rawlsian theory of justice generates a strong environmental and animal rights ethic. These modifications include significant changes in the conditions of the contract situation vis-a-vis A Theory of Justice, but I argue that these modifications are in fact more consistent with Rawls’ basic assumptions about the functions of a veil of ignorance and a thin theory of the good.

In this paper I present the basic outlines of a nonstandard interpretation of Sein und Zeit. The merit of this interpretation is that it brings out and develops some of the radical possibilities contained in this rich text, possibilities which, I believe, have yet to be given their due. On the basis of this interpretation it is clear not only how Heidegger’s ontology departs from its Cartesian and Kantian predecessors, but also how his ontology puts the traditional mind/body problem, and (...) the problem of the external world, onto radically new grounds. However, unlike standard interpretations of Sein und Zeit, I argue that these new grounds neither resolve, nor dissolve, these problems, and that Heidegger’s discussion of the so-called “scandal of philosophy” is misleading at best.

Compassion is a prosocial motivation that is critical to the development and survival of the human species. Cultivating compassion involves developing deep wisdom, insight, and understanding into the nature and causes of human suffering; and wisdom and commitment to take positive action to alleviate suffering. This perspective piece discusses how compassion relates to the context of modern technology, which has developed at a rapid pace in recent decades. While advances in digital technology build on humankind’s vast capacity to develop practical (...) tools that promise to enrich our lives and improve our social connections, in reality the effects are often far from benign. The motives underlying the development of many contemporary digital platforms seem rooted in competitiveness and capitalism; while modern social media and online platforms are having a profound and pervasive impact on the mental health and wellbeing of humans around the globe. Nonetheless, digital technology holds considerable potential to promote compassionate insight, wisdom, and prosocial behavior. We reflect on the current state of technology within human society and examine the notion of compassionate technologies; discuss how contemporary paradigm shifts such as the inclusive design movement may be harnessed to build tools and platforms that promote collective good and increase prosocial behavior; and highlight examples of initiatives that are harnessing modern technology to advance democracy, collective knowledge, and personal freedoms and agency.

Over the past decade, teaching and learning in virtual worlds has been at the forefront of many higher education institutions around the world. The DEHub Virtual Worlds Working Group (VWWG) consisting of Australian and New Zealand higher education academics was formed in 2009. These educators are investigating the role that virtual worlds play in the future of education and actively changing the direction of their own teaching practice and curricula. 47 academics reporting on 28 Australian higher education institutions present an (...) overview of how they have changed directions through the effective use of virtual worlds for diverse teaching and learning activities such as business scenarios and virtual excursions, role-play simulations, experimentation and language development. The case studies offer insights into the ways in which institutions are continuing to change directions in their teaching to meet changing demands for innovative teaching, learning and research in virtual worlds. This paper highlights the ways in which the authors are using virtual worlds to create opportunities for rich, immersive and authentic activities that would be difficult or not possible to achieve through more traditional approaches.

Rationale: Deep brain stimulation (DBS) of the hippocampus is proposed for enhancement of memory impaired by injury or disease. Many pre-clinical DBS paradigms can be addressed in epilepsy patients undergoing intracranial monitoring for seizure localization, since they already have electrodes implanted in brain areas of interest. Even though epilepsy is usually not a memory disorder targeted by DBS, the studies can nevertheless model other memory-impacting disorders, such as Traumatic Brain Injury (TBI). Methods: Human patients undergoing Phase II invasive monitoring for (...) intractable epilepsy were implanted with depth electrodes capable of recording neurophysiological signals. Subjects performed a delayed-match-to-sample (DMS) memory task while hippocampal ensembles from CA1 and CA3 cell layers were recorded to estimate a multi-input, multi-output (MIMO) model of CA3-to-CA1 neural encoding and a memory decoding model (MDM) to decode memory information from CA3 and CA1 neuronal signals. After model estimation, subjects again performed the DMS task while either MIMO-based or MDM-based patterned stimulation was delivered to CA1 electrode sites during the encoding phase of the DMS trials. Each subject was sorted (post hoc) by prior experience of repeated and/or mild-to-moderate brain injury (RMBI), TBI, or no history (control) and scored for percentage successful delayed recognition (DR) recall on stimulated vs. non-stimulated DMS trials. The subject’s medical history was unknown to the experimenters until after individual subject memory retention results were scored. Results: When examined compared to control subjects, both TBI and RMBI subjects showed increased memory retention in response to both MIMO and MDM-based hippocampal stimulation. Furthermore, effects of stimulation were also greater in subjects who were evaluated as having pre-existing mild-to-moderate memory impairment. Conclusion: These results show that hippocampal stimulation for memory facilitation was more beneficial for subjects who had previously suffered a brain injury (other than epilepsy), compared to control (epilepsy) subjects who had not suffered a brain injury. This study demonstrates that the epilepsy/intracranial recording model can be extended to test the ability of DBS to restore memory function in subjects who previously suffered a brain injury other than epilepsy, and support further investigation into the beneficial effect of DBS in TBI patients.

The work reported in this monograph was begun in the winter of 1967 in a graduate seminar at Berkeley. Many of the basic data were gathered by members of the seminar and the theoretical framework presented here was initially developed in the context of the seminar discussions.

Developmental psychology currently faces a deep puzzle: most children before 4 years of age fail elicited-response false-belief tasks, but preverbal infants demonstrate spontaneous false-belief understanding. Two main strategies are available: cultural constructivism and early-belief understanding. The latter view assumes that failure at elicited-response false-belief tasks need not reflect the inability to understand false beliefs. The burden of early-belief understanding is to explain why elicited-response false-belief tasks are so challenging for most children under 4 years of age. The goal of this (...) article is to offer a pragmatic framework whose purpose is to discharge this burden. (shrink)

In information societies, operations, decisions and choices previously left to humans are increasingly delegated to algorithms, which may advise, if not decide, about how data should be interpreted and what actions should be taken as a result. More and more often, algorithms mediate social processes, business transactions, governmental decisions, and how we perceive, understand, and interact among ourselves and with the environment. Gaps between the design and operation of algorithms and our understanding of their ethical implications can have severe consequences (...) affecting individuals as well as groups and whole societies. This paper makes three contributions to clarify the ethical importance of algorithmic mediation. It provides a prescriptive map to organise the debate. It reviews the current discussion of ethical aspects of algorithms. And it assesses the available literature in order to identify areas requiring further work to develop the ethics of algorithms.

Considerable variation exists not only in the kinds of transposable elements (TEs) occurring within the genomes of different species, but also in their abundance and distribution. Noting a similarity to the assortment of organisms among ecosystems, some researchers have called for an ecological approach to the study of transposon dynamics. However, there are several ways to adopt such an approach, and it is sometimes unclear what an ecological perspective will add to the existing co-evolutionary framework for explaining transposon-host interactions. This (...) review aims to clarify the conceptual foundations of transposon ecology in order to evaluate its explanatory prospects. We begin by identifying three unanswered questions regarding the abundance and distribution of TEs that potentially call for an ecological explanation. We then offer an operational distinction between evolutionary and ecological approaches to these questions. By determining the amount of variance in transposon abundance and distribution that is explained by ecological and evolutionary factors, respectively, it is possible empirically to assess the prospects for each of these explanatory frameworks. To illustrate how this methodology applies to a concrete example, we analyzed whole-genome data for one set of distantly related mammals and another more closely related group of arthropods. Our expectation was that ecological factors are most informative for explaining differences among individual TE lineages, rather than TE families, and for explaining their distribution among closely related as opposed to distantly related host genomes. We found that, in these data sets, ecological factors do in fact explain most of the variation in TE abundance and distribution among TE lineages across less distantly related host organisms. Evolutionary factors were not significant at these levels. However, the explanatory roles of evolution and ecology become inverted at the level of TE families or among more distantly related genomes. Not only does this example demonstrate the utility of our distinction between ecological and evolutionary perspectives, it further suggests an appropriate explanatory domain for the burgeoning discipline of transposon ecology. The fact that ecological processes appear to be impacting TE lineages over relatively short time scales further raises the possibility that transposons might serve as useful model systems for testing more general hypotheses in ecology.

Inventions of Teaching: A Genealogy is a powerful examination of current metaphors for and synonyms of teaching. It offers an account of the varied and conflicting influences and conceptual commitments that have contributed to contemporary vocabularies--and that are in some ways maintained by those vocabularies, in spite of inconsistencies and incompatibilities among popular terms. The concern that frames the book is how speakers of English invented (in the original sense of the word, "came upon") our current vocabularies for teaching. Conceptually, (...) this book is unique in the educational literature. As a whole, it presents an overview of the major underlying philosophical and ideological concepts and traditions related to knowledge, learning, and teaching in the Western world, concisely introducing readers to the central historical and contemporary discourses that shape current discussions and beliefs in the field. Because the organization of historical, philosophical, theoretical, and etymological information is around key conceptual divergences in Western thought rather than any sort of chronology, this text is not a linear history, but several histories--or, more precisely, it is a genealogy. Specifically, it is developed around breaks in opinion that gave or are giving rise to diverse interpretations of knowledge, learning, and teaching--highlighting historical moments in which vibrant new figurative understandings of teaching emerged and moments at which they froze into literalness. The book is composed of two sorts of chapters, "branching" and "teaching." Branching chapters include an opening treatment of the break in opinion, separate discussions of each branch, and a summary of the common assumptions and shared histories of the two branches. Teaching chapters offer brief etymological histories and some of the practical implications of the terms for teaching that were coined, co-opted, or redefined within the various traditions. Inventions of Teaching: A Genealogy is an essential text for senior undergraduate and graduate courses in curriculum studies and foundations of teaching and is highly relevant as well for students, faculty, and researchers across the field of education.

For much of the past two centuries, religion has been understood as a universal phenomenon, a part of the “natural” human experience that is essentially the same across cultures and throughout history. Individual religions may vary through time and geographically, but there is an element, religion, that is to be found in all cultures during all time periods. Taking apart this assumption, Brent Nongbri shows that the idea of religion as a sphere of life distinct from politics, economics, or (...) science is a recent development in European history—a development that has been projected outward in space and backward in time with the result that religion now appears to be a natural and necessary part of our world. Examining a wide array of ancient writings, Nongbri demonstrates that in antiquity, there was no conceptual arena that could be designated as “religious” as opposed to “secular.” Surveying representative episodes from a two-thousand-year period, while constantly attending to the concrete social, political, and colonial contexts that shaped relevant works of philosophers, legal theorists, missionaries, and others, Nongbri offers a concise and readable account of the emergence of the concept of religion.

Income inequality in the US has now reached levels not seen since the 1920s. Management, as a field of scholarly inquiry, has the potential to contribute in significant ways to our understanding of recent inequality trends. We review and assess recent research, both in the management literature and in other fields. We then delineate a conceptual framework that highlights the mechanisms through which business practice may be linked to income inequality. We then outline four general areas in which management scholars (...) are uniquely positioned to contribute to ongoing research: data and description, organizational dynamics, collective action, and value flows and tradeoffs. To stimulate future research, we highlight a number of relevant research questions and link these questions to existing management research streams that could be leveraged to address them. (shrink)

Planned home birth has been considered by some to be consistent with professional responsibility in patient care. This article critically assesses the ethical and scientific justification for this view and shows it to be unjustified. We critically assess recent statements by professional associations of obstetricians, one that sanctions and one that endorses planned home birth. We base our critical appraisal on the professional responsibility model of obstetric ethics, which is based on the ethical concept of medicine from the Scottish and (...) English Enlightenments of the 18th century. Our critical assessment supports the following conclusions. Because of its significantly increased, preventable perinatal risks, planned home birth in the United States is not clinically or ethically benign. Attending planned home birth, no matter one’s training or experience, is not acting in a professional capacity, because this role preventably results in clinically unnecessary and therefore clinically unacceptable perinatal risk. It is therefore not consistent with the ethical concept of medicine as a profession for any attendant to planned home birth to represent himself or herself as a “professional.” Obstetric healthcare associations should neither sanction nor endorse planned home birth. Instead, these associations should recommend against planned home birth. Obstetric healthcare professionals should respond to expressions of interest in planned home birth by pregnant women by informing them that it incurs significantly increased, preventable perinatal risks, by recommending strongly against planned home birth, and by recommending strongly for planned hospital birth. Obstetric healthcare professionals should routinely provide excellent obstetric care to all women transferred to the hospital from a planned home birth. The professional responsibility model of obstetric ethics requires obstetricians to address and remedy legitimate dissatisfaction with some hospital settings and address patients’ concerns about excessive interventions. Creating a sustained culture of comprehensive safety, which cannot be achieved in planned home birth, informed by compassionate and respectful treatment of pregnant women, should be a primary focus of professional obstetric responsibility.

Charles Sanders Peirce was born in September 1839 and died five months before the guns of August 1914. He is perhaps the most important mind the United States has ever produced. He made significant contributions throughout his life as a mathematician, astronomer, chemist, geodesist, surveyor, cartographer, metrologist, engineer, and inventor. He was a psychologist, a philologist, a lexicographer, a historian of science, a lifelong student of medicine, and, above all, a philosopher, whose special fields were logic and semiotics. He is (...) widely credited with being the founder of pragmatism. In terms of his importance as a philosopher and a scientist, he has been compared to Plato and Aristotle. He himself intended "to make a philosophy like that of Aristotle." Peirce was also a tormented and in many ways tragic figure. He suffered throughout his life from various ailments, including a painful facial neuralgia, and had wide swings of mood which frequently left him depressed to the state of inertia, and other times found him explosively violent. Despite his consistent belief that ideas could find meaning only if they "worked" in the world, he himself found it almost impossible to make satisfactory economic and social arrangements for himself. This brilliant scientist, this great philosopher, this astounding polymath was never able, throughout his long life, to find an academic post that would allow him to pursue his major interest, the study of logic, and thus also fulfill his destiny as America's greatest philosopher. Much of his work remained unpublished in his own time, and is only now finding publication in a coherent, chronologically organized edition. Even more astounding is that,despite many monographic studies, there has been no biography until now, almost eighty years after his death. Brent has studied the Peirce papers in detail and enriches his account with numerous quotations from letters by Peirce and by his friends. This is a fascinating account of a p. (shrink)

The underlying structures that are common to the world's languages bear an intriguing connection with early emerging forms of “core knowledge” (Spelke & Kinzler, 2007), which are frequently studied by infant researchers. In particular, grammatical systems often incorporate distinctions (e.g., the mass/count distinction) that reflect those made in core knowledge (e.g., the non-verbal distinction between an object and a substance). Here, I argue that this connection occurs because non-verbal core knowledge systematically biases processes of language evolution. This account potentially explains (...) a wide range of cross-linguistic grammatical phenomena that currently lack an adequate explanation. Second, I suggest that developmental researchers and cognitive scientists interested in (non-verbal) knowledge representation can exploit this connection to language by using observations about cross-linguistic grammatical tendencies to inspire hypotheses about core knowledge.
