It is argued that “human-centredness” will be an important characteristic of systems that learn tasks from human users, as the difficulties in inductive inference rule out learning without human assistance. The aim of “programming by example” is to create systems that learn how to perform tasks from their human users by being shown examples of what is to be done. Just as the user creates a learning environment for the system, so the system provides a teaching opportunity for the user, (...) and emphasis is placed as much on facilitating successful teaching as on incorporating techniques of machine learning. If systems can “learn” repetitive tasks, their users will have the power to decide for themselves which parts of their jobs should be automated, and teach the system how to do them — reducing their dependence on intermediaries such as system designers and programmers.This paper presents principles for programming by example derived from experience in creating four prototype learners: for technical drawing, text editing, office tasks, and robot assembly. A teaching metaphor (a) enables the user to demonstrate a task by performing it manually, (b) helps to explain the learner's limited capabilities in terms of a persona, and (c) allows users to attribute intentionality. Tasks are represented procedurally, and augmented with constraints. Suitable mechanisms for attention focusing are necessary in order to control inductive search. Hidden features of a task should be made explicit so that the learner need not embark on the huge search entailed by hypothesizing missing steps. (shrink)

There isn’t much understanding in some marriages. My sister has six [children] and another has eight. I said to one of them that she shouldn’t have any more. And she said “What can I do?

The number of women living with HIV/AIDS is increasing worldwide, and there is an urgent public health need to develop new user-initiated HIV prevention methods, including microbicides. Although funding for microbicide development has increased since 2000, financial support is provided predominantly by governmental agencies and private foundations. Many donors, including the US Agency for International Development (USAID) and the US National Institutes of Health (NIH), have policies that restrict how research funds may be used. Among these are the now-rescinded Mexico (...) City Policy, elements of the US Foreign Assistance Act, and restrictions on non-study-related care. The effect of these restrictions on the design and conduct of clinical research is poorly understood. As part of a recent mapping exercise conducted by the Global Campaign for Microbicides, we reviewed the impact of donor restrictions on seven HIV prevention trials. We found considerable confusion within the HIV prevention field as to whether and how Mexico City and other policies affect the use of research funds. We also found that these donor-imposed policies limited the level of care provided to trial participants and the types of capacity building projects undertaken. (shrink)

Employing three methods of assessing meaning, this book demonstrates that the thousands of human identities in English coalesce into groups that are recognizable as role sets in the contemporary social institutions of economy, kinship, religion, polity, law, education, medicine, sport, and arts. After establishing a theoretical and a methodological framework for his empirical work, David Heise presents the results obtained when meanings are assessed via dictionary definitions, collocates, and word associations. A close comparison of the results reveals that similar (...) outcomes are obtained through each of these three different approaches of defining meaning. The final chapter summarizes the study, considers the benefits and limitations of studying society via language, and applies the results to describing how individuals operate social institutions via their daily social interactions. Aspects of this book will be of interest to social psychologists, sociologists, and linguists. (shrink)

As new HIV prevention tools are developed, researchers face a number of ethical and logistic questions about how and when to include novel HIV prevention strategies and tools in the standard prevention package of ongoing and future HIV prevention trials. Current Joint United Nations Programme on HIV/AIDS /World Health Organization guidance recommends that participants in prevention trials receive ‘access to all state of the art HIV risk reduction methods’, and that decisions about adding new tools to the prevention package be (...) made in consultation with ‘all relevant stakeholders’. The guidance, however, leaves open questions of both process and implementation. In March 2009, the Global Campaign for Microbicides, UNAIDS and the Centers for Disease Control and Prevention convened a consultation to develop practical answers to these questions. Fifty-nine diverse participants, including researchers, ethicists, advocates and policymakers, worked to develop consensus criteria on when to include new HIV prevention tools in future trials. Participants developed a set of questions to guide decision-making, including: whether the method has been recommended by international bodies or adopted at a national level; the size of the effect and weight of the evidence; relevance to the trial population; whether the tool has been approved or introduced in the trial country; whether adding the tool might lead to trial futility; outstanding safety issues and status of the trial. Further work is needed to develop, implement and evaluate approaches to facilitate meaningful stakeholder participation in this deliberative process. (shrink)

Many sentences can be interpreted both as a metaphor and as a literal claim, depending on the context. The aim of this paper is to show that there are discourse-based systematic constraints on the identification of an utterance as metaphorical, literal, or both (as in the case of twice-apt metaphors), from a normative point of view. We claim that the key is contextual coherence. In order to substantiate this claim, we introduce a novel notion of context as a rich and (...) heterogeneous body of information, including previous discourse, elements coming from the surroundings of the utterance, background information, and Questions Under Discussion (QUD) issued from these three sources. We then define contextual coherence as a relation between what we call the minimal paraphrase of the metaphor and the context, and argue that for an interpretation to be coherent two conditions must be met. First, the minimal paraphrase must address some question in the QUD stack. Second, it must be externally consistent, i.e. consistent with the available contextual information. Finally, we argue that an approach based on contextual coherence is better suited to deal with twice-true and twice-apt metaphors than traditional approaches based on semantic deviance or pragmatic lack of fit.

In this paper, we propose an account of metaphor identification on the basis of contextual coherence. In doing so, we build on previous work by Nicholas Asher and Alex Lascarides that appeals to rhetorical relations in order to explain discourse structure and the constraints on the interpretation of metaphor that follow from it. Applying this general idea to our problem, we will show that rhetorical relations are sometimes insufficient and sometimes inadequate for deciding whether a given utterance is a case (...) of metaphor. They are insufficient, since rhetorical relations fall short at times of providing a basis for disambiguating between literal and metaphorical interpretations. In such cases, contextual information other than previous discourse needs to enter the picture. To this effect, we bring the idea of external consistency into play. Beyond that, though, we will argue that rhetorical relations are sometimes inadequate to account for coherence, if conceived as relations among sentences only. The reason is that extra-linguistic elements of the situation in which the sentence is uttered may be crucial for getting at the preferred interpretation. To account for these cases, we allow rhetorical relations to connect both with previous discourse and with extra-linguistic situations. In our final refinement of the notion of contextual coherence, we forfeit any appeal to rhetorical relations in favour of Questions Under Discussion (QUD). We defend the view that this account does not only explain the same sort of cases. What is more, it solves the issue of metaphor identification in impoverished contexts. (shrink)

The subject animal welfare is increasingly in the public discourse. Consumers and policymakers are increasingly demanding products that are produced under increased animal welfare standards. The profession of the farmer involuntarily gets into disrepute. Many consumers want fundamental changes in pig farming, but are not aware of the consequences of implementation. In this representative study, consumers (n = 1101) were asked about their assessment of 33 animal welfare measures with regard to their importance and the feasibility of implementing those measures. (...) With the help of a four-field matrix, both the perceived importance and the feasibility of the animal welfare measures surveyed were brought together. The results show four possibilities: important and easy to implement, important and not feasible, not important and easy to implement as well as not important and not feasible. The results show that any outdoor access to pasture ranks first, followed by any outdoor access to straw bedding. The results can make a significant contribution to future communication with critical consumers concerning the implementation of higher animal welfare levels, as it becomes clearer how realistic consumers are about the feasibility of several animal welfare measures. Furthermore, the results could prove useful for the design of animal welfare programs and could help famers making targeted decisions concerning stable construction and management. (shrink)

This paper offers both exegetical and systematic reconsiderations of Donald Davidson’s view on metaphor. In his essay What Metaphors Mean, Davidson argued against the idea that metaphors have any kind of propositional content beyond the literal meaning of the relevant sentence. Apart from this negative claim, Davidson also made a constructive proposal by suggesting that metaphor’s distinctive effect is to prompt a mental state of seeing-as. These two points seem connected insofar as Davidson makes the following assumptions. First, metaphors cause (...) their distinctive effects in an a-rational way. Second, seeing-as is a nonpropositional mental state. If we side with Davidson in thinking of meaning as rational and propositional, then it follows that metaphors’ distinctive effects cannot be an instance of meaning. They have the wrong format and are brought about in the wrong way. Against this background, I distinguish a strong reading and a modest reading of Davidson’s wrong-kind objection to metaphorical meaning. By taking into account some of Davidson’s later pronouncements on the matter, this paper aims to show that Davidson did not hold on to the strong version of the wrong-kind objection. This would open up the way to conceiving of metaphorical meaning in terms of speaker’s meaning, were it not for the fact that Davidson sticks to the wrong-way objection. The two concluding sections examine the cogency of the wrong-way objection as applied to metaphorical speaker’s meaning, and offer a model for thinking about the a-rational mental causation Davidson thought metaphors exhibit.

The Cambridge Journal of Economics witnessed an important debate between Mark Pernecky and Paul Wojick on the one side and Rod Thomas on the other about the usefulness of Thomas Kuhn's sociology and philosophy of science in explaining why Keynes's revolutionary ideas exposed in the General Theory have been 'lost in translation'. This brief note is an attempt to reconcile Pernecky and Wojick's claim that Keynes's new economics of the General Theory and Walrasian General Equilibrium are incommensurable paradigms in a (...) Kuhnian understanding and Thomas's critique that – if they were incommensurable – Pernecki and Wojick's appraisal of Keynes's paradigm as a better approximation to the 'real world' than Walsrasian General Equilibrium is inconsistent within that very Kuhnian framework.

Affect Control Theory was developed to address some issues in role theory. However, a mathematical formulation allowed the theory to expand rapidly to a variety of substantive issues, such as labeling, attributions, emotions, and the impact of settings on social interaction. Formalization raised theoretical issues that might have been neglected otherwise, and helped in defining the boundaries of the theory. A reasonable lesson to draw from development of affect control theory is that even modest mathematical analyses can expand theoretical productivity.

Walras' law is a central tenet of economic theory. For mainstream economics, it is a 'plausibility check' for model-building; for heterodox economists, the refutation of Walras' law is key to understanding Keynes' revolutionary contribution to a new economic paradigm. The purpose of this short research note is to elaborate on the possibility of a refutation of Walras' law and to inquire into its preconditions. It will be argued that this can be achieved on the basis of an alternative pre-analytic vision (...) of a genuine monetary economy as foreshadowed by John Maynard Keynes. (shrink)

In an empirical study, we compared how lay people judge motivation enhancement as opposed to cognitive enhancement. We found alienation is not seen as a danger associated with either form of enhancement. Cognitive enhancement is seen as more morally wrong than motivation enhancement, and users of cognitive enhancement tend to be judged as less deserving of praise and success than users of motivation enhancement. These more negative judgments of cognitive enhancement may be driven by differences in perceived fairness rather than (...) differences in effort exerted by the user, although lay people generally see effort as necessary to deservingness of praise and success.

In this timely book L.W. Sumner addresses these issues within the wider context of palliative care for patients in the dying process.

Recently, the gender asterisk has become more widespread in grammatical gender languages in order to represent all genders. Such gender-fair language is intended to help better address women and other genders and make their interests and achievements more visible. Critics often argue this would make the language less comprehensible and less aesthetically appealing. Two experiments examined the effects of the gender asterisk on text comprehensibility, aesthetic perception, and interest. N = 159 and N = 127 participants were randomly provided with (...) a text in either masculine-only form or alternatively in gender-fair language with the gender asterisk. The results of the first experiment showed no impairment of comprehensibility and aesthetic evaluation of the texts by the gender asterisk and no effect on interest in the game, while the second experiment showed significant impairments of comprehensibility, aesthetic evaluation, and interest in the game by the gender asterisk. The proportion of singular forms is discussed as a possible explanation for the different results. Experiment 1 predominantly used plural forms like die Spieler*innen and did not include forms such as der*die Spieler*in, whereas Experiment 2 included many such more complex singular forms. We argue that this issue might be crucial, and that it deserves full attention in future studies. (shrink)

L. Nathan Oaklander is one of the leading philosophers of time defending the tenseless or B-Theory of time. He has remained at the forefront of this field since the early 1980s and today he is arguably the most formidable opponent of the tensed or A-theory of time. Much of the direction of the debate in this field for the past twenty years or so, especially in regards to the new tenseless theory of time, has been influenced by Oaklander's work. This (...) book presents a carefully argued defense of the tenseless theory of time. The topics discussed include: the ontology of A- and B-theories of time; presentism; the open future theory; the A/B theory; defending the B-theory of time; temporal experience; temporal semantics; and time, identity, responsibility, and freedom.

Edmund Gettier is Professor Emeritus at the University of Massachusetts, Amherst. This short piece, published in 1963, seemed to many decisively to refute an otherwise attractive analysis of knowledge. It stimulated a renewed effort, still ongoing, to clarify exactly what knowledge comprises.

This new edition of the classic Contemporary Theories of Knowledge has been significantly updated to include analyses of the recent literature in epistemology.

This edited volume represents a unique addition to the available literature on animal ethics, animal studies, and neuroethics. Its goal is to expand discussions on animal ethics and neuroethics by weaving together different threads: philosophy of mind and animal minds, neuroscientific study of animal minds, and animal ethics. Neuroethical questions concerning animals’ moral status, animal minds and consciousness, animal pain, and the adequacy of animal models for neuropsychiatric disease have long been topics of debate in philosophy and ethics, and more (...) recently also in neuroscientific research. The book presents a transdisciplinary blend of voices, underscoring different perspectives on the broad questions of how neuroscience can contribute to our understanding of nonhuman minds, and on debates over the moral status of nonhuman animals. All chapters were written by outstanding scholars in philosophy, neuroscience, animal behavior, biology, neuroethics, and bioethics, and cover a range of issues and species/taxa. Given its scope, the book will appeal to scientists and students interested in the debate on animal ethics, while also offering an important resource for future researchers. Chapter 13 of this book is available open access under a CC BY 4.0 license at link.springer.com. (shrink)

Le philosophe Jean Baudrillard (1929-2007) a-t-il vraiment existé? Que reste-t-il de lui? "Une élégance certaine de la pensée", affirme l'un de ses meilleurs interprètes, François L'Yvonnet. Le philosophe de La Société de consommation, des Stratégies fatales et des Cool Memories s'attachait à l'idée du fragment comme mode de pensée : car dans le détail, tout est parfait, c'est dans sa reproduction que tout se complique. François L'Yvonnet explore cinq fragments de la philosophie de Jean Baudrillard et de sa biographie pour (...) mieux saisir l'éclat et la jubilation d'une pensée toujours vivante et contemporaine.
