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)

Neural organization contains a wealth of facts from all areas of brain research and provides a useful overview of physiological data for those working outside the immediate field. Furthermore, it gives a good example that the approach of dynamical system theory together with the concepts of cooperative and competitive interaction can be fruitful for an interdisciplinary approach to cognition.

In the discussion about consequences of the release of genetically modified (GM) crops, the meaning of the term “environmental damage” is difficult to pin down. We discuss some established concepts and criteria for understanding and evaluating such damages. Focusing on the concepts of familiarity, biological integrity, and ecosystem health, we argue that, for the most part, these concepts are highly ambiguous. While environmental damage is mostly understood as significant adverse effects on conservation resources, these concepts may not relate directly to (...) effects on tangible natural resources but rather to parameters of land use or ecological processes (e.g., the concept of biological integrity). We stress the importance of disclosing the normative assumptions underlying damage concepts and procedures for the evaluation of damages by GM crops. A conceptualization of environmental damage should precede its operationalization. We recommend an unambiguous definition for damage developed earlier and recommend that evaluation criteria be based on this. However, a general damage definition cannot replace case-specific operationalization of damage, which remains an important future challenge. (shrink)

In educational hypermedia environments, students are often confronted with potential sources of distraction arising from additional information that, albeit interesting, is unrelated to their current task goal. The paper investigates the conditions under which distraction occurs and hampers performance. Based on theories of volitional action control it was hypothesized that interesting information, especially if related to a pending goal, would interfere with task performance only when working on easy, but not on difficult tasks. In Experiment 1, 66 students learned about (...) probability theory using worked examples and solved corresponding test problems, whose task difficulty was manipulated. As a second factor, the presence of interesting information unrelated to the primary task was varied. Results showed that students solved more easy than difficult probability problems correctly. However, the presence of interesting, but task-irrelevant information did not interfere with performance. In Experiment 2, 68 students again engaged in example-based learning and problem solving in the presence of task-irrelevant information. Problem-solving difficulty was varied as a first factor. Additionally, the presence of a pending goal related to the task-irrelevant information was manipulated. As expected, problem-solving performance declined when a pending goal was present during working on easy problems, whereas no interference was observed for difficult problems. Moreover, the presence of a pending goal reduced the time on task-relevant information and increased the time on task-irrelevant information while working on easy tasks. However, as revealed by mediation analyses these changes in overt information processing behavior did not explain the decline in problem-solving performance. As an alternative explanation it is suggested that goal conflicts resulting from pending goals claim cognitive resources, which are then no longer available for learning and problem solving.

Heise delves into the ethical issues behind Cheating for High School students from a conference for ethicists, in addition to a discussion with students and moderators towards the subject.

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)

A model of when and where saccades are made necessarily incorporates a model of the “When” and “Where” of target selection. We suggest that the framework proposed by Findlay & Walker does not specify sufficiently how selection processes contribute to the spatial and temporal determinants of saccade generation. Examples from across-trial priming in visual search and from the inhibition of temporally segmented distractors show linkage between the processes involved in computing when and where selection operates, so that there is cooperation (...) rather than competition between so-called Where and When pathways. Aspects of spatial selection may also determine the remote distractor effect on saccades. The detailed relations between the processes involved in selection and saccade generation may be best understood in relation to detailed computational accounts of the processes. (shrink)

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)

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.

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?

Or the men get jealous and think their (...) wives are with other men.—Rene, a 29-year old Peruvian womanGender violence is a major yet often underrecognized obstacle to reproductive choice. In both the abortion rights movement in the United States and the reproductive health movement globally, the “enemy” of self-determination and choice is usually seen as imposing from the top down. In the North, it is the government—through the courts, the legislature, and bureaucratic rulemaking—that threatens to “take away” women’s reproductive autonomy. The image is one of the public sphere invading that which is private—of the state interfering with a woman’s right to control her own body. (shrink)

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.

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)

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.

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.
