The purpose of this study was to investigate experimentally the extent to which children’s novel word learning and story comprehension from eBooks depends on the relevance of interactive eBook features. A story was created in the lab to incorporate novel word-object pairs. The story was read to preschoolers (3-5 years old, N = 103) using one of the three books: noninteractive control, interactive-relevant, interactive-irrelevant. Novel word learning and story comprehension were assessed with posttests in which children picked target objects from (...) an array and sorted story events into sequences, respectively. Findings indicate that word learning and story comprehension were similar across all three books, suggesting that simple interactive features – whether relevant or irrelevant to the story – had little impact on learning in this controlled experiment.

“The physics of representation” aims to define the word “representation” as used in the neurosciences, argue that such representations as described in neuroscience are related to and usefully illuminated by the representations generated by modern neural networks, and establish that these entities are “representations in good standing”. We suggest that Poldrack succeeds in, exposes some tensions between the broad use of the term in neuroscience and the narrower class of entities that he identifies in the end, and between the meaning (...) of “representation” in neuroscience and in psychology in, and fails in. This results in some hard choices: give up on the broad scope of the term in neuroscience or continue to embrace the broad, psychologically inflected sense of the term, and deny the entities generated by neural nets are representations in the relevant sense.

Background: Despite an increase in health research conducted in Africa, there are still inadequate human resources with research ethics training and lack of local long-term training opportunities in research ethics. A research ethics training program named United States-Mali Research Ethics Training Program (US-Mali RETP) was established through a partnership between the George Washington University Milken Institute School of Public Health (GWSPH), USA and University of Sciences, Techniques & Technologies of Bamako (USTTB), to address the critical need for improved bioethics training, (...) leadership, and policy in Mali. Methods: The aims of the capacity building programme are achieved by leveraging US and Africa-based expertise to strengthen research ethics education and capacity through: (1) intensive faculty development to design ethics training curricula; (2) development of a research ethics specialization within the existing Masters of Public Health program (MPH); and (3) establishing professional development courses through short-term training workshops and webinars to address research and professional needs in ethics. Results: The program will strengthen USTTB’s capacity of research ethics by training at least 15 MPH students over 5 years to prepare the next generation of ethics researchers. During the first two years of the program, a new ethics training curricula was developed, two cohorts of Master’s students were enrolled, and a series of webinars and workshops were conducted with participation of Malian and international researchers. Conclusions: US-Mali RETP will promote a sustainable bioethics enterprise at USTTB, and enable dissemination of research ethics training to increase health research capacity in Mali. (shrink)

Development of the knowledge base for a profession depends on research and scholarship that builds on the insights and work of scholars within the discipline and is disseminated through the literature. The purpose of this study was to examine a unique collection of 79 articles selected by editors as representative of their nursing journals. Articles were assessed for congruence with long‐standing values and conceptual definitions of nursing, and the extent to which they built on prior literature published in nursing. Articles (...) were scored based on whether they reflected four characteristics of nursing as a discipline (holism, social context, goal of health, and consistency with common definitions of nursing); an abstract score on the extent to which the title, abstract, or keywords indicated a general focus on nursing; and a distinction score based on whether the article distinguished nurses or nursing from other providers. Fifty of the articles received an article score of 4, indicating all four disciplinary characteristics were present in the article's content. While the majority of the articles were congruent with fundamental nursing values and perspectives, only 28% of the sources cited were from nursing sources. The lack of citations to nursing literature, coupled with an assessment that reveals gaps in substantive content that builds on nursing knowledge, raises questions about the future of nursing perspectives in the literature.

In the United States, final amendments to the Federal Policy for the Protection of Human Subjects (“the Common Rule”) were published on January 19, 2017, and they will take effect on January 21, 2019. One of the most widely discussed provisions is that for the first time, federal regulations governing research with humans authorize the use of broad consent for future, unspecified research on individually identifiable biospecimens and associated data. Many questions have been raised about broad consent, including what effect (...) it will have on research and whether it adequately protects the interests of research participants.There are lessons to be learned for the U.S. and other countries by looking to countries that already have experience with broad consent for biobank collection and with the storage and subsequent use of the biospecimens and data. This article describes how broad consent works in five countries—Canada (in Quebec), Israel, Nigeria, Taiwan, and the United Kingdom—and with different types of biobanks: national biobanks, federated biobanks, and regional biobanks. Evaluating the provisions and challenges of the broad consent approaches in these countries can inform policies for this increasingly used approach to biobank regulation. (shrink)

Judges are typically tasked to consider sentencing benefits but not costs. Previous research finds that both laypeople and prosecutors discount the costs of incarceration when forming sentencing attitudes, raising important questions about whether professional judges show the same bias during sentencing. To test this, we used a vignette-based experiment in which Minnesota state judges reviewed a case summary about an aggravated robbery and imposed a hypothetical sentence. Using random assignment, half the participants received additional information about plausible negative consequences of (...) incarceration. As predicted, our results revealed a mitigating effect of cost exposure on prison sentence term lengths. Critically, these findings support the conclusion that policies that increase transparency in sentencing costs could reduce sentence lengths, which has important economic and social ramifications.

This article aims to outline some of the ways in which issues of migration and employment relations have been studied in the European context, cross referencing recent interventions in the USA. The argument is a discussion of some of the different dimensions of migration and the way debates within Industrial Relations have been shaped. More specifically, the article will look at the way trade unions have made the ethical turn towards questions of migration and equality. The article will observe the (...) way these issues have been academically framed and the manner in which the ‘problem’ of migration is conceptualized. It will attempt to provide a framework for discussing the way we have been analysing these issues and the ethical dimensions of these discussions. The relevance of the article is that institutionally responding to migration is not solely a question of adjusting employment relations or Industrial Relations institutions to various ‘new’ constituencies. The article will show that the topic raises issues as to how we actually understand what the study of employment and especially Industrial Relations are. The article also argues that there is a growing need for researchers to be aware of ethical issues when studying in the area of migration, and to be sensitive to competing voices and methodologies in this area. In particular we need approaches that are multidimensional and that emphasize the history and context of change in social constituencies, the new mechanisms of representation within communities, the role of the political in terms of discourses and resources, and the broad play and spaces of regulation and social policy.

The diverse array of plants at Kew is a haven for wildlife throughout the year. In spring, enchanting wildlfowl babies appear; summer flowers attract a host of insect pollinators; come autumn, parakeets and squirrels raid chestnuts, while in winter swans court – this is Heather Angel’s Wild Kew. In all, a stunning array of photographs and advice, the result of devoting a year to capturing Kew’s wildlife.

This study investigates the hypothesis that the advantage corporate social performance (CSP) yields in attracting human resources depends on the degree of job choice possessed by the job seeking population. Results indicate that organizational CSP is positively related to employer attractiveness for job seekers with high levels of job choice but not related for populations with low levels suggesting advantages to firms with high levels of CSP in the ability to attract the most qualified employees.

Participants compared the mental capacities of various human and nonhuman characters via online surveys. Factor analysis revealed two dimensions of mind perception, Experience and Agency. The dimensions predicted different moral judgments but were both related to valuing of mind.

We characterize the modal logics of elementary classes of Kripke frames as precisely those modal logics that are axiomatized by modal axioms synthesized in a certain effective way from "quasi-positive" sentences of hybrid logic. These are pure positive hybrid sentences with arbitrary existential and relativized universal quantification over nominals. The proof has three steps. The first step is to use the known result that the modal logic of any elementary class of Kripke frames is also the modal logic of the (...) closure of this class under disjoint unions, generated subframes, bounded morphic images, and ultraroots. This latter class can be defined by the first-order sentences of a special syntactic form (called pseudo-equations by Goldblatt) that are valid in the former class. The second step is to translate these pseudo-equations into equivalent quasi-positive hybrid sentences. In the third and main step, we show that any quasi-positive sentence S generates an infinite set of modal formulas called "approximants," which together axiomatize a canonical modal logic that is sound and complete for the class of frames validating S. The proof is analogous to standard proofs of Sahlqvist's theorem. It generalizes to sets of quasi-positive sentences. The main result now follows. (shrink)

The practice of ‘management euthanasia’, in which zoos kill otherwise healthy surplus animals, is a controversial one. The debate over the permissibility of the practice tends to divide along two different views in animal ethics—animal rights and animal welfare. Traditionally, those arguments against the practice have come from the animal rights camp, who see it as a violation of the rights of the animal involved. Arguments in favour come from the animal welfare perspective, who argue that as the animal does (...) not suffer, there is no harm in the practice and it is justified by its potential benefits. Here, I argue that an expansion of the welfare view, encompassing longevity and opportunities for positive welfare, give stronger considerations against management euthanasia, which then require greater benefits to justify its use.

One of the biggest problems in applications of animal welfare science is our ability to make comparisons between different individuals, both within and across species. Although welfare science provides methods for measuring the welfare of individual animals, there’s no established method for comparing measures between individuals. In this paper I diagnose this problem as one of underdetermination—there are multiple conclusions given the data, arising from two sources of variation that we cannot distinguish: variation in the underlying target variable (welfare experience) (...) and in the relationship of measured indicators to the target. I then describe some of the possible methods of making comparisons, based on the use of similarity assumptions that will have greater or lesser justification in different circumstances, and the alternative methods we may use when direct comparisons are not possible. In the end, all our available options for making welfare comparisons are imperfect, and we need to make explicit context-specific decisions about which will be best for the task at hand while acknowledging their potential limitations. Future developments in our understanding of the biology of sentience will help strengthen our methods of making comparisons. (shrink)

We show that the loosely guarded and packed fragments of first-order logic have the finite model property. We use a construction of Herwig and Hrushovski. We point out some consequences in temporal predicate logic and algebraic logic.

This article examines the impact on Spartan historiography of Chapter IV of de Ste. Croix’s Origins of the Peloponnesian War, focusing on his discussions of Spartan politics and society in Sections v–vi. These sections fit oddly within the overall chapter, but they blew a breath of fresh air into Spartan studies through their revisionist approach, intimations of the socio-economic bases of policy-making, and extended accounts of ‘real-life’ political episodes across the classical period. Along with Moses Finley’s near-contemporary article on Sparta, (...) OPW significantly influenced the following generation of British historians (including the author), although they often adopted different interpretations or developed new perspectives on Spartan society only hinted at by de Ste. Croix. OPW also had an important impact on Western European historiography on Spartan politics. Its combination of constitutional and societal approaches gives it an enduring currency in the context of developing Historical Institutionalist approaches to political studies. (shrink)

For any finite n 3 there are two atomic n-dimensional cylindric algebras with the same atom structure, with one representable, the other, not.Hence, the complex algebra of the atom structure of a representable atomic cylindric algebra is not always representable, so that the class RCAn of representable n-dimensional cylindric algebras is not closed under completions. Further, it follows by an argument of Venema that RCAn is not axiomatisable by Sahlqvist equations, and hence nor by equations where negation can only occur (...) in constant terms.Similar results hold for relation algebras.

Recent discussions in animal welfare have emphasised the importance of animal agency—the ability of animals to make choices and exert control over their environment in a way that aligns with their needs and preferences. In this paper, we discuss the importance of animal agency for welfare and examine how use of some types of animal–computer interaction can enable animals to exercise more agency in captive environments through increased choice and control, cognitive challenge, and social interactions; as well as considering some (...) of the potential limitations of such efforts.

We prove decidability of satisfiability of sentences of the monodic packed fragment of first-order temporal logic with equality and connectives Until and Since, in models with various flows of time and domains of arbitrary cardinality. We also prove decidability over models with finite domains, over flows of time including the real order.

We prove that every first-order formula that is invariant under quasi-injective bisimulations is equivalent to a formula of the hybrid logic . Our proof uses a variation of the usual unravelling technique. We also briefly survey related results, and show in a standard way that it is undecidable whether a first-order formula is invariant under quasi-injective bisimulations.

Extending a construction of Andreka, Givant, and Nemeti (2019), we construct some finite vector spaces and use them to build finite non-representable relation algebras. They are simple, measurable, and persistently finite, and they validate arbitrary finite sets of equations that are valid in the variety RRA of representable relation algebras. It follows that there is no finitely axiomatisable class of relation algebras that contains RRA and validates every equation that is both valid in RRA and preserved by completions of relation (...) algebras. Consequently, the variety generated by the completions of representable relation algebras is not finitely axiomatisable. This answers a question of Maddux (2018). (shrink)

A countably infinite relational structure M is called absolutely ubiquitous if the following holds: whenever N is a countably infinite structure, and M and N have the same isomorphism types of finite induced substructures, there is an isomorphism from M to N. Here a characterisation is given of absolutely ubiquitous structures over languages with finitely many relation symbols. A corresponding result is proved for uncountable structures.

Abstract Truth-telling is a key issue within the nurse–patient relationship. Nurses make decisions on a daily basis regarding what information to tell patients. This paper analyses truth-telling within an end of life scenario. Virtue ethics provides a useful philosophical approach for exploring decisions on information disclosure in more detail. Virtue ethics allows appropriate examination of the moral character of the nurse involved, their intention, ability to use wisdom and judgement when making decisions and the virtue of truth-telling. It is appropriate (...) to discuss nursing as a 'practice' in relation to virtue ethics. This is achieved through consideration of the implications of arguments made by Alasdair MacIntyre who believes that qualities such as honesty, courage and justice are virtues because they enable us to achieve the internal goods of practices.

This book is an investigation into metaphysics: its aims, scope, methodology and practice.

ABSTRACTAutonomous weapons systems pose many challenges in complex battlefield environments. Previous discussions of them have largely focused on technological or policy issues. In contrast, we focus here on the challenge of trust in an AWS. One type of human trust depends only on judgments about the predictability or reliability of the trustee, and so are suitable for all manner of artifacts. However, AWSs that are worthy of the descriptor “autonomous” will not exhibit the required strong predictability in the complex, changing (...) contexts of war. Instead, warfighters need to develop deeper, interpersonal trust that is grounded in understanding the values, beliefs, and dispositions of the AWS. Current acquisition, training, and deployment processes preclude the development of such trust, and so there are currently no routes for a warfighter to develop trust in an AWS. We thus survey three possible changes to current practices in order to facilitate the type of deep trust that is required for appropri... (shrink)

A conjecture of Gabbay (1981) states that any class of flows of time having the property known as finite H-dimension admits a finite set of expressively complete one-dimensional temporal connectives. Here we show that the class of 'circular' structures refutes the generalisation of this conjecture to Kripke frames. We then construct from this class, by a general method, a new class of irreflexive transitive flows of time that refutes the original conjecture. Our paper includes full descriptions of a method for (...) establishing finite H-dimension for a class of structures and of the technique for extending finite H-dimension to other classes, and an introduction surveying the area of expressive completeness.

‘The problem of Spartan land tenure is one of the most vexed in the obscure field of Spartan institutions.’ Walbank's remark is as true today as when it was written nearly thirty years ago. Controversy surrounding this subject has a long tradition going back to the nineteenth century and the last thirty years have witnessed no diminution in the level of disagreement, as is demonstrated by a comparison of the differing approaches in the recent works by Cartledge, Cozzoli, David and (...) Marasco. Although another study runs the risk of merely adding one more hypothesis to the general state of uncertainty, a fundamental reassessment of the question is required, not least because of its significance for the historian's interpretation of the overall character of Spartiate society. Through the introduction of a new perspective it may be possible to advance our understanding of the subject. In Section I of this essay I shall attempt to review several influential scholarly theories and to examine their feasibility and the reliability of the evidence upon which they are based. Section II will begin to construct a more plausible alternative account which is based upon more trustworthy evidence. Finally, Section III will discuss a comparatively underemphasised aspect of the topic, the property rights of Spartiate women, which suggests a rather different interpretation of the character of land tenure and inheritance from those more usually adopted.

This article sketches a taxonomy of the activities in which bioethics academics engage, including activities that may make their own research more impactful, from little or no engagement outside academia to activism or extreme activism. This taxonomy, the first of its kind, may be useful in determining what obligations bioethics academics have in relation to activism and activities that fall short of activism.

_ Source: _Page Count 29 This essay offers a working analysis of the trait of intellectual perseverance. It argues that intellectual perseverance is a disposition to overcome obstacles, so as to continue to perform intellectual actions, in pursuit of one’s intellectual goals. The trait of intellectual perseverance is not always an intellectual virtue. This essay provides a pluralist analysis of what makes it an intellectual virtue, when it is one. Along the way, it argues that the virtue of intellectual perseverance (...) can be contrasted with both a vice of deficiency and a vice of excess. It also suggests that the virtues of intellectual courage and intellectual self-control are types of intellectual perseverance. The essay ends with several open questions about the virtue of intellectual perseverance. My hope is that this essay will stimulate further interest in, and analysis of, this important intellectual trait. (shrink)

If, as the new tenseless theory of time maintains, there are no tensed facts, then why do our emotional lives seem to suggest that there are? This question originates with Prior’s ‘Thank Goodness That’s Over’ problem, and still presents a significant challenge to the new B-theory of time. We argue that this challenge has more dimensions to it than has been appreciated by those involved in the debate so far. We present an analysis of the challenge, showing the different questions (...) that a B-theorist must answer in order to meet it. The debate has focused on the question of what is the object of my relief when an unpleasant experience is past. We outline the prevailing response to this question. The additional, and neglected, questions are, firstly—‘Why does the same event elicit different emotional responses from us depending on whether it is in the past, present, or future?’ And secondly—‘Why do we care more about proximate future pain than about distant future pain?’ We give B-theory answers to these questions, which appeal to evolutionary considerations.

While the Value-Free Ideal (VFI) had many precursors, it became a solidified bulwark of normative claims about scientific reasoning and practice in the mid-twentieth century. Since then, it has played a central role in the philosophy of science, first as a basic presupposition of how science should work, then as a target for critique, and now as a target for replacement. In this paper, we will argue that a narrow focus on the VFI is misguided, because the VFI coalesced in (...) the midst of other important shifts in the relationship between science and society. In particular, the mid-twentieth century saw the acceptance of the “social contract for science,” a tacit agreement between scientists and government officials, and more broadly between science and society. It was built around three core concepts: a distinction between basic and applied science, a conception of scientific freedom that limited social responsibility for scientists, and a justification for public funding of basic science in the form of the linear model. Within the conceptual framework of the social contract for science, it is clearer both (1) why the VFI was adopted, (2) why it is difficult to replace the VFI within the old social contract, and (3) how we need to revise the social contract for science in order to replace the VFI.

In this paper, we introduce a new fragment of the first-order temporal language, called the monodic fragment, in which all formulas beginning with a temporal operator have at most one free variable. We show that the satisfiability problem for monodic formulas in various linear time structures can be reduced to the satisfiability problem for a certain fragment of classical first-order logic. This reduction is then used to single out a number of decidable fragments of first-order temporal logics and of two-sorted (...) first-order logics in which one sort is intended for temporal reasoning. Besides standard first-order time structures, we consider also those that have only finite first-order domains, and extend the results mentioned above to temporal logics of finite domains. We prove decidability in three different ways: using decidability of monadic second-order logic over the intended flows of time, by an explicit analysis of structures with natural numbers time, and by a composition method that builds a model from pieces in finitely many steps.

With increasing attention given to wild animal welfare and ethics, it has become common to depict animals in the wild as existing in a state dominated by suffering. This assumption is now taken on board by many and frames much of the current discussion; but needs a more critical assessment, both theoretically and empirically. In this paper, we challenge the primary lines of evidence employed in support of wild animal suffering, to provide an alternative picture in which wild animals may (...) often have lives that are far more positive than is commonly assumed. Nevertheless, while it is useful to have an alternative model to challenge unexamined assumptions, our real emphasis in this paper is the need for the development of effective methods for applying animal welfare science in the wild, including new means of data collection, the ability to determine the extent and scope of welfare challenges and opportunities, and their effects on welfare. Until such methods are developed, discussions of wild animal welfare cannot go beyond trading of intuitions, which as we show here can just as easily go in either direction. (shrink)

Functional theories posit that emotions are elicited by particular goal-related situations that represented adaptive problems and that emotions are evolved features of coordinated responses to those situations. Yet little theory or research has addressed the evolutionary aspects of these theories. We apply five criteria that can be used to judge whether features are adaptations. There is evidence that sadness, anger, and anxiety relate to unique changes in physiology, cognition, and behavior, those changes are correlated, situations that give rise to emotions (...) are consistent, and emotions are complex. To date, there is little experimental evidence regarding whether discrete emotions resolve adaptive problems and do so relatively efficiently. Evidence supporting all criteria is required to claim that discrete emotions are evolved features. (shrink)

The construct of “mindfulness” has increasingly become a focus of research related to meditation practices and techniques. There is a growing body of research indicating clinical efficacy from therapeutic use, while cognitive neuroscience has provided an insight into the brain regions and mechanisms involved. Significantly, these approaches converge to suggest that attention is an important mechanism with trainable sub-components. This article discusses the role of attention and argues that memory has been neglected as a potential key mechanism in mindfulness–meditation practices. (...) Specifically, it proposes that working memory offers a useful model for integrating and understanding the different mental devices that are used in meditation and suggests a model with the potential to provide a comprehensive account of how the apparent benefits of these practices arise. This call for a more comprehensive and integrated approach is necessary if the study and application of meditation are to become more than a parochial concern. (shrink)

I suggest an alternative approach that: (i) explains what makes fanaticism and extremism vicious in the very many cases in which they are; but also (ii) allows for cases in which fanaticism and extremism aren’t vices and may even be liberatory-virtues. My hope is that this approach might serve as a resource for those in liberatory (...) struggles. (shrink)

Although epistemic values have become widely accepted as part of scientific reasoning, non-epistemic values have been largely relegated to the "external" parts of science (the selection of hypotheses, restrictions on methodologies, and the use of scientific technologies). I argue that because of inductive risk, or the risk of error, non-epistemic values are required in science wherever non-epistemic consequences of error should be considered. I use examples from dioxin studies to illustrate how non-epistemic consequences of error can and should be considered (...) in the internal stages of science: choice of methodology, characterization of data, and interpretation of results.

Measurement of subjective animal welfare creates a special problem in validating the measurement indicators used. Validation is required to ensure indicators are measuring the intended target state, and not some other object. While indicators can usually be validated through looking for correlation between target and indicator under controlled manipulations, this is not possible when the target state is not directly accessible. In this paper, I outline a four-step approach using the concept of robustness, that can help with validating indicators of (...) subjective animal welfare. (shrink)
