Astrobiology aims to determine the distribution and diversity of life in the universe. But as the word “biosignature” suggests, what will be detected is not life itself, but an observation implicating living systems. Our limited access to other worlds suggests this observation is more likely to reflect out‐of‐equilibrium gasses than a writhing octopus. Yet, anything short of a writhing octopus will raise skepticism about what has been detected. Resolving that skepticism requires a theory to delineate processes due to life and (...) those due to abiotic mechanisms. This poses an existential question for life detection: How do astrobiologists plan to detect life on exoplanets via features shared between non‐living and living systems? We argue that you cannot without an underlying theory of life. We illustrate this by analyzing the hypothetical detection of an “Earth 2.0” exoplanet. Without a theory of life, we argue the community should focus on identifying unambiguous features of life via four areas: examining life on Earth, building life in the lab, probing the solar system, and searching for technosignatures. Ultimately, we ask, what exactly do astrobiologists hope to learn by searching for life? (shrink)

Families and surrogates sometimes use religious themes to justify their insistence on aggressive end‐of‐life care. Their hope that “God will work a miracle” can halt negotiations with health care professionals and lead to litigation. The possibility of “re‐imagining” religious themes, to broaden their scope and present a wider vision of the Christian tradition, may offer a solution.

The current rise of neurodevelopmental disorders poses a critical need to detect risk early in order to rapidly intervene. One of the tools pediatricians use to track development is the standard growth chart. The growth charts are somewhat limited in predicting possible neurodevelopmental issues. They rely on linear models and assumptions of normality for physical growth data – obscuring key statistical information about possible neurodevelopmental risk in growth data that actually has accelerated, non-linear rates-of-change and variability encompassing skewed distributions. Here, (...) we use new analytics to profile growth data from 36 newborn babies that were tracked longitudinally for 5 months. By switching to incremental (velocity-based) growth charts and combining these dynamic changes with underlying fluctuations in motor performance – as the transition from spontaneous random noise to a systematic signal – we demonstrate a method to detect very early stunting in the development of voluntary neuromotor control and to flag risk of neurodevelopmental derail.

Sometimes researchers explicitly or implicitly conceive of authorship in terms of moral or ethical rights to authorship when they are dealing with authorship issues. Because treating authorship as a right can encourage unethical behaviours, such as honorary and ghost authorship, buying and selling authorship, and unfair treatment of researchers, we recommend that researchers not conceive of authorship in this way but view it as a description about contributions to research. However, we acknowledge that the arguments we have given for this (...) position are largely speculative and that more empirical research is needed to better ascertain the benefits and risks of treating authorship on scientific publications as a right.

The paper discusses regularisation of dualities. A given duality between (concrete) categories, e.g. a variety of algebras and a category of representation spaces, is lifted to a duality between the respective categories of semilattice representations in the category of algebras and the category of spaces. In particular, this gives duality for the regularisation of an irregular variety that has a duality. If the type of the variety includes constants, then the regularisation depends critically on the location or absence of constants (...) within the defining identities. The role of schizophrenic objects is discussed, and a number of applications are given. Among these applications are different forms of regularisation of Priestley, Stone and Pontryagin dualities.

The claim that world politics looks different depending upon one's location is now commonplace within the field of International Relations (IR). This exciting new textbook offers students a text that speaks to the main concepts, categories and issues of world politics from the vantagepoints of the global South. International Relations from the Global South: Worlds of Difference examines the ways in which world politics have been addressed by traditional core approaches and explores the limitations of these treatments for understanding both (...) Southern and Northern experiences of the "international". The book encourages the reader to consider how key ideas have been developed in the discipline, and through systematic interventions by contributors from around the globe, aims at both transforming and enriching the dominant terms of scholarly debate. Each chapter is written according to a common structure, providing concrete examples of global South perspectives on world affairs, as well as discussion questions and suggestions for further reading. Drawing on a wide range of literatures, case studies and knowledges, this textbook is the first to speak to and from the global South, and will provide a new dimension to a variety of courses on international relations and IR theory. It is essential reading for students and teachers alike. (shrink)

We describe a general problem solving mechanism that is especially suited for performing a particular form of abductive inference, or best-explanation finding. A problem solver embodying this mechanism synthesizes composite hypotheses. It does so by by combining hypothesis parts as a means to the satisfaction of explanatory goals. In this way it is able to arrive at complex, integrated conclusions which are not pre-stored.The intent is to present a computationally-feasible, task-specific problem solver for a particular information processing task which is (...) nevertheless of very great generality. The task is that of synthesizing coherent composite explanatory hypotheses based upon a prestored, and possibly vast collection of hypothesis-generating “concepts”. The authors’ claim is nothing less than to have shown, in a new sense, and surpassing all other work in this area, how it is computationally possible for an agent to come to “know”, based upon the evidence of the case.

Boiger and Mesquita (2012) present a social constructionist perspective on emotion that argues for its multilevel contextualization through social interactions, relationships, and culture. The present comments offer a response to the authors’ call for input from other disciplines. We provide a sociological perspective on emotion construction at each of the contextual levels discussed by Boiger and Mesquita, and discuss a model that can address interdependencies between these levels. Our remarks are intended to identify additional literature that can be brought to (...) bear on multilevel emotion construction and to put forward some ideas for future research on the subject.

Red-2 is a computer program for red-cell antibody identification, a piece of "normal science". Abstracting from Red-2, a general problem solving mechanism is described that is especially suited for performing a form of abductive inference or best explanation finding. A problem solver embodying this mechanism synthesizes composite hypotheses by combining hypothesis parts. This is a common task of intelligence, and a component of scientific reasoning. The work addresses the question, 'How is science possible?' by showing how a simple but powerful (...) form of hypothesis synthesis is computationally feasible. (shrink)

This volume reveals the breadth of More’s writing and includes a rich selection of illustrations and artwork. The book provides the most complete picture of More’s work available, serving as a major resource (...) for early modern scholars, teachers, students, and the general reader. (shrink)

In my contribution to this volume, I (BHS) comment on on the stultifying rhetoric of contemporary analytic moral theory as illustrated in Judith Jarvis Thomson's Tanner Lectures, with particular reference to Thomson's anxieties about the moral relativism exhibited by college freshman and to her efforts--quite strained, in my view, and inevitably unsuccessful--to demonstrate the existence of objective judgments in matters of morality and taste .

This study examines the self-reported ethics of both current and future advertising practitioners, and compares their responses to four scenarios and 17 statements on advertising ethics. Stepwise discriminant analysis was used to determine the extent to which both groups applied the classical ethical theory of deontology to the scenarios and statements. Results indicate significant differences between both groups. For example, current advertising practitioners are significantly less likely than future practitioners to apply deontology to decision making. The implications of these results (...) are discussed and suggestions for future research are outlined. (shrink)

In Hegel's Critique of Liberalism , Steven B. Smith examines Hegel's critique of rights-based liberalism and its relevance to contemporary political concerns. Smith argues that Hegel reformulated classic liberalism, preserving what was of value while rendering it more attentive to the dynamics of human history and the developmental structure of the moral personality. Hegel's goal, Smith suggests, was to find a way of incorporating both the ancient emphasis on the dignity and even architectonic character of political life (...) with the modern concern for freedom, rights, and mutual recognition. Smith's insightful analysis reveals Hegel's relevance not only to contemporary political philosophers concerned with normative issues of liberal theory but also to political scientists who have urged a revival of the state as a central concept of political inquiry.

Workplace ostracism is a prevalent and painful experience. The majority of studies focus on negative outcomes of ostracism, with less work examining employees’ potential adaptive responses to it. Further, scholars have suggested that such responses depend on employee attributions, yet little research has taken an attributional perspective on workplace ostracism. Drawing on sociometer theory and attribution theory we develop and test a model that investigates why and under what circumstances ostracized employees engage in adaptive responses to ostracism. Specifically, we argue (...) that ostracized employees feel greater levels of shame and, in turn, are motivated to engage in greater ingratiation behavior toward their ostracizers. However, we predict that perceptions of ostracizers’ competence and warmth shape different attributional processes, which influence the degree to which the ostracized employee experience shame and, in turn, is motivated to engage in ingratiation behavior. Results of a three-wave, time-lagged survey support our prediction that shame mediates the relationship between coworker ostracism and ingratiation behavior. Moreover, results support our three-way interaction, such that coworkers who report higher levels of ostracism and who perceive their coworkers as more (vs. less) competent and more (vs. less) warm report higher shame, and, in turn, ingratiation behavior. Theoretical and practical implications, as well as avenues for future research, are discussed. (shrink)

SummaryUtah has the highest total fertility of any state in the United States and also the highest proportion of population affiliated with the Church of Jesus Christ of Latter-day Saints. Data were used from the 1996 Utah Health Status Survey to investigate how annual household income, education and affiliation with the LDS Church affect fertility for married women in Utah. Younger age and higher education were negatively correlated with fertility in the sample as a whole and among non-LDS respondents. Income (...) was negatively associated with fertility among non-LDS respondents. However, income was positively correlated with fertility among LDS respondents. This association persisted when instrumental variables were used to address the potential simultaneous equations bias arising from the potential endogeneity of income and fertility. The LDS religion's pronatalist stance probably encourages childbearing among those with higher income. (shrink)

We presuppose a position of scientific realism to the effect (i) that the world exists and (ii) that through the working out of ever more sophisticated theories our scientific picture of reality will approximate ever more closely to the world as it really is. Against this background consider, now, the following question: 1. Do the empirical theories with the help of which we seek to approximate a good or true picture of reality rest on any non-empirical presuppositions? One can answer (...) this question with either a 'yes' or a 'no'. 'No' is the preferred answer of most contemporary methodologists -- Murray Rothbard is one distinguished counterexample to this trend -- who maintain that empirical theories are completely free of non-empirical ('a priori') admixtures and who see science as a matter of the gathering of pure 'data' obtained through simple observation. From such data scientific propositions are then supposed to be somehow capable of being established. (shrink)
