While there are many issues to be raised in using lethal autonomous robotic weapons (beyond those of remotely operated drones), we argue that the most important question is: should the decision to take a human life be relinquished to a machine? This question is often overlooked in favor of technical questions of sensor capability, operational questions of chain of command, or legal questions of sovereign borders. We further argue that the answer must be ?no? and offer several reasons for banning (...) autonomous robots. (1) Such a robot treats a human as an object, instead of as a person with inherent dignity. (2) A machine can only mimic moral actions, it cannot be moral. (3) A machine run by a program has no human emotions, no feelings about the seriousness of killing a human. (4) Using such a robot would be a violation of military honor. We therefore conclude that the use of an autonomous robot in lethal operations should be banned. (shrink)

The concept of vulnerability is deployed in bioethics to, amongst other things, identify and remedy harms to participants in research, yet although nonhuman animals in experimentation seem intuitively to be vulnerable, this concept and its attendant protections are rarely applied to research animals. I want to argue, however, that this concept is applicable to nonhuman animals and that a new taxonomy of vulnerability developed in the context of human bioethics can be applied to research animals. This taxonomy does useful explanatory (...) work, helping to pinpoint the limitations of the 3Rs/welfare approach currently adopted in the context of animal experimentation. On this account, the 3Rs/welfare approach fails to deliver for nonhuman animals in experimentation because it effectively addresses only one element of their vulnerability (inherent) and paradoxically through the institution of Animal Ethics Committees intended to protect experimental animals in fact generates new vulnerabilities that exacerbate their already precarious situation.

The antisaccade task provides a model paradigm that sets the inhibition of a reflexively driven behaviour against the volitional control of a goal-directed behaviour. The stability and adaptability of antisaccade performance was investigated in 23 neurologically healthy individuals. Behaviour and brain function were measured using functional magnetic resonance imaging (fMRI) prior to and immediately following two weeks of daily antisaccade training. Participants performed antisaccade trials faster with no change in directional error rate following two weeks of training; however this increased (...) speed came at the cost of the spatial accuracy of the saccade (gain) which became more hypometric following training. Training on the antisaccade task resulted in increases in fMRI activity in the fronto-basal ganglia-parietal-cerebellar ocular motor network. Following training, antisaccade latency was positively associated with fMRI activity in the frontal and supplementary eye fields, anterior cingulate and intraparietal sulcus; antisaccade gain was negatively associated with fMRI activity in supplementary eye fields, anterior cingulate, intraparietal sulcus and cerebellar vermis. In sum, the results suggest that following training, larger antisaccade latency is associated with larger activity in fronto-parietal-cerebellar ocular motor regions, and smaller antisaccade gain is associated with larger activity in fronto-parietal ocular motor regions.

This paper is an exercise in intellectual history, an attempt to understand how a specific term—”informal logic”— came to be interpreted in so many different ways. I trace the emergence and development of “informal logic” to help explain the many different meanings, how they emerged and how they are related. This paper is also, to some degree, an account of a movement that developed outside the mainstream of philosophy, whose origins lie in a desire to make logic useful (echoing Dewey).

An investigation is presented in which a computer simulation model (DIAGNOSER) is used to develop and test predictions for behavior of subjects in a task of medical diagnosis. The first experiment employed a process‐tracing methodology in order to compare hypothesis generation and evaluation behavior of DIAGNOSER with individuals at different levels of expertise (students, trainees, experts). A second experiment performed with only DIAGNOSER identified conditions under which errors in reasoning in the first experiment could be related to interpretation of specific (...) data items. Predictions derived from DIAGNOSER's performance were tested in a third experiment with a new sample of subjects. Data from the three experiments indicated that (1) form of diagnostic reasoning was similar for all subjects trained in medicine and for the simulation model, (2) substance of diagnostic reasoning employed by the simulation model was parable with that of the more expert subjects, and (3) errors in subjects' reasoning were attributable to deficiencies in disease knowledge and the interpretation of specific patient data cues predicted by the simulation model.

The work presented here investigates the process by which one group of individuals solves the problem of detecting deceptions created by other agents. A field experiment was conducted in which twenty-four auditors (partners in international public accounting firms) were asked to review four cases describing real companies that, unknown to the auditors, had perpetrated financial frauds. While many of the auditors failed to detect the manipulations in the cases, a small number of auditors were consistently successful. Since the detection of (...) frauds occurs infrequently in the work of a given auditor, we explain success by the application of powerful heuristics gained from experience with deceptions in everyday life. These heuristics implement a variation of Dennett's intentional stance strategy, which is based on interpreting detected inconsistencies in the light of the Deceiver's (i.e., management's) goals and possible actions. We explain failure to detect deception by means of perturbations (bugs) in the domain knowledge of accounting needed to apply these heuristics to the specific context of financial statement fraud. We test our theory by showing that a computational model of fraud detection that employs the proposed heuristics successfully detects frauds in the cases given to the auditors. We then modify the model by introducing perturbations based on the errors made by each of the auditors in the four cases. The resulting models account for 84 of the 96 observations (i.e., 24 auditors × four cases) in our data. (shrink)

Haptic-based vibrotactile biofeedback (BF) is a promising technique to improve rehabilitation of balance in stroke patients. However, the extent to which BF training changes temporal structure of the center of pressure (CoP) trajectories remains unknown. This study aimed to investigate the effect of vibrotactile BF training on the temporal structure of CoP during quiet stance in chronic stroke patients using detrended fluctuation analysis (DFA). Nine chronic stroke patients (age; 81.56±44 months post-stroke) received a balance training regimen using a vibrotactile BF (...) system twice a week over four weeks. A Wii Balance board was used to record five 30 s trials of quiet stance pre- and post-training at 50 Hz. DFA revealed presence of two linear scaling regions in CoP indicating presence of fast- and slow-scale fluctuations. Averaged across all trials, fast-scale fluctuations showed persistent dynamics ( = 1.05 ±.08 for ML and  = 0.99 ±.17 for AP) and slow-scale fluctuations were anti-persistent ( = 0.35 ±.05 for ML and  = 0.32 ±.05 for AP). The slow-scale dynamics of ML CoP in stroke patients decreased from pre-training to post-BF training ( = 0.40 ±.13 vs. 0.31 ±.09). These results suggest that the vibrotactile BF training affects postural control strategy used by chronic stroke patients in the ML direction. Results of the DFA are further discussed in the context of balance training using vibrotactile BF and interpreted from the perspective of intermittent control of upright stance. (shrink)

The 2010 Quinnipiac cheerleading case raises interesting questions about the nature of both cheerleading and sport, as well as about the moral character of each. In this paper we explore some of those questions, and argue that no form of college cheerleading currently in existence deserves, from a moral point of view, to be recognized as a sport for Title IX purposes. To reach that conclusion, we evaluate cheerleading using a quasi-legal argument based on the NCAA’s definition of sport and (...) conclude that cheerleading fails to qualify as a legitimate sport. A philosophical argument leads to the same conclusion, primarily because of the essential entertainment-aspect of cheerleading. We then examine a consequentialist moral case for making cheerleading an intercollegiate sport and argue that the balance of moral reasons is against doing so. Finally, we look at cheerleading’s newest offspring – Acrobatics and Tumbling, and STUNT – and express our moral reservations about their current claims to be worthy of Title IX recognition. While we would not claim that any single one of our arguments is decisive, we are convinced that the cumulative weight of the arguments against granting intercollegiate sport status to any of the forms of cheerleading or its derivatives is, at present, irresistible.

The decision of the German regional court in Cologne on 26 June 2012 to prohibit the circumcision of minors is important insofar as it recognises the qualitative similarities between the practice and other prohibited invasive rites, such as female genital cutting. However, recognition of similarity poses serious questions with regard to liberal public policy, specifically with regard to the exceptionalist treatment demanded by certain circumcising groups. In this paper, I seek to advance egalitarian means of dealing with invasive rites which (...) take seriously cultural diversity, minimise harm and place responsibility for the burdens and consequences of beliefs upon those who promote practices.

In multicausal abductive tasks a person must explain some findings by assembling a composite hypothesis that consists of one or more elementary hypotheses. If there are n elementary hypotheses, there can be up to 2n composite hypotheses. To constrain the search for hypotheses to explain a new observation, people sometimes use their current explanation—the previous evidence and their present composite hypothesis of that evidence; however, it is unclear when and how the current explanation is used. In addition, although a person's (...) current explanation can narrow the search for a hypothesis, it can also blind the problem solver to alternative, possibly better, explanations. This paper describes a model of multicausal abductive reasoning that makes two predictions regarding the use of the current explanation. The first prediction is that the current explanation is not used to explain new evidence if there is a simple (i.e., nondisjunctive, concrete) hypothesis to account for that evidence. The second prediction is that the current explanation is used when attempting to discriminate among several alternative hypotheses for new evidence. These hypotheses were tested in three experiments. The results are consistent with the second prediction: the current explanation is used when discriminating among alternative hypotheses. However, the first prediction—that the current explanation is not used when a simple hypothesis can account for new data—received only limited support. Participants used the current explanation to constrain their interpretation of new data in 46.5% of all trials. This suggests that context‐independent strategies compete with context‐dependent ones—an interpretation that is consistent with recent work on strategy selection during problem solving. (shrink)

Pets often factor in older adults’ health behaviors and decisions. However, the degree to which issues related to pet ownership are encountered or addressed by professionals working with this population remains unknown. The aim of this study was to identify specific issues stemming from pet ownership professionals had encountered in their work with older adults, people living with dementia, and care partners. An interdisciplinary sample completed an online survey addressing pet ownership issues encountered in their work. Descriptive statistics, t-tests, and (...) repeated measures ANOVAs were used to analyze quantitative data. A conventional content analysis was used to analyze open-ended responses to an item asking about “other” issues encountered in their work with these populations. The professionals estimated 46.29% of clients had been pet owners, 41.23% regularly asked about pets, and 79.22% had encountered issues related to pet ownership. Specific issues raised to the professionals varied by type of client. The professionals reported older adults most often raised getting pet items into the home and concerns about their pets’ health. The issues most often raised by people living with dementia to the professionals were planning for the pet due to a housing transition and basic pet care. Care partners focused on basic pet care and planning for the pet due to a housing transition. The professionals themselves most often raised the issues of basic pet care, concerns about falling, and the pets’ behavior. Professionals who entered clients’ homes were more likely to raise issues stemming from pet ownership compared to those who reported they did not enter clients’ homes in their current job, t = 5.59, p < 0.00001. The eleven new issues identified by the content analysis underscored how the health and wellbeing of people and their pets are linked. The results of this study provide strong evidence that professionals do encounter issues related to pet ownership. Including issues stemming from pet ownership into procedures, policies, and programs is likely to have positive impacts on those served by and working in the geriatric workforce. (shrink)

In this paper we propose a new way of conceptualizing animals in experimentation – the animal-as-patient. Construing and treating animals as patients offers a way of successfully addressing some of the entrenched epistemological and ethical problems within a practice of animal experimentation directed to human clinical benefit. This approach is grounded in an epistemological insight and builds on work with so-called ‘pet models’. It relies upon the occurrence and characterization of analogous human and nonhuman animal diseases, where, if certain criteria (...) of homology and mechanism are met, the animal simultaneously becomes a patient and a spontaneous model of the human disease.

The dominant notions of consciousness in the West are anchored in a peculiar matrix of dissociated sensibility held in place by unthematized body practices. It is misleading to evaluate spiritual and philosophical notions of consciousness simply from the point of view of verbal, logical analysis, when they are expressions of these deeply rooted experiential sensibilities, deliberately cultivated over long years of habituation. There is a dramatic difference between how the West thinks of body practices as irrelevant to analyzing states of (...) consciousness and how other cultures make direct links between these practices and the shaping of consciousness. For at least the last 150 years in Europe and the United States a number of teachers have developed body practices in deliberate resistance to the dualistic structurings of mentalities and physicality. They constitute a cultural movement of resistance shaped by the recognition of the mistaken notions embodied in Western dualism. An example is given of the work of Bonnie Bainbridge Cohen, the creator of the School of Body‐Mind Centering. Key Words: Embodiment, Somatics, Cultivation, Practices, Dualism. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Dramatic Frame and Philosophic Idea in PlatoWilliam A. JohnsonIn a minority of plato's dialogues the central philosophic discourse is presented indirectly, refracted through the lens of a dramatic frame of more or less complexity.1 Scholars typically divorce the question of the dramatic frame from the philosophy of the dialogues: the frame is often simply set to one side by analytic philosophers, and tends to be considered in terms of (...) characterization, narrative technique, intratextual associations and the like by students of the "literary Plato."2 I here consider the four dialogues that mark Plato's most ambitious experiments in construction of a complex narrative frame: Phaedo, Symposium, Parmenides, and Theaetetus. By focusing on the effect that the indirect narration has on the reader, I construct a view of these narrative experiments that puts them together with the philosophic program of the dialogues. Baldly stated: I argue that the elaborate indirectness of the dramatic frame means to reflect, and to make vivid for the reader, not only the remove between written representation and the doing of philosophy, but also the remove between perceptible and Ideal world as suggested in Plato's vision of the Ideas.PhaedoAt the beginning of Plato's Phaedo, Echecrates asks Phaedo to tell him about the last hours of Socrates' life. He points out, "None of the people in Phlius go to Athens much these days, and it is a long time since we had any visitor from there who could give us any definite information, except that he was executed by drinking hemlock" (57a–b).3 The reader thereby comes to realize: (1) the conversation is situated in Phlius, a somewhat remote town on the Peloponnesus far from Athens (and far from anyone who might be able to correct or verify Phaedo's account); (2) since "no Phliasian goes to Athens much these days" and "it is a long time since we had any visitor from Athens who could give us any definite information," Phaedo's arrival in Phlius comes at a significant temporal distance from Socrates' death; (3) on the same grounds, the reader is led to wonder how long a time might have lapsed between this conversation and its report to Plato back in Athens (if indeed this is based on a report, on which see below); (4) on the other hand, Phaedo, as an intimate of Socrates, is presumed to be able to provide "definite information" (σαφές τι). Echecrates goes on to ask Phaedo to "be kind enough to give us a really detailed account" (σαφέστατα, 58d2) of Socrates' last day. When Phaedo says that he is willing, Echecrates urges again: "Now try to describe every detail as carefully as you can" (, 58d8). The bulk of Phaedo will be this account, told by Phaedo to Echecrates. The desire for accurate detail is emphasized. But Echecrates' insistence on accuracy sits uneasily with the spatial and temporal remove introduced at the beginning. How accurate, really, is Phaedo's account?The answer to this question—is the account accurate?—is, however, not at issue here. What is more interesting, or at least what interests me, is the fact that the dramatic frame seems designed to bring such questions into play. Bald historical questions (Did Socrates really say that? How does Plato know? Is Phaedo's memory accurate?) may seem unsophisticated, but they are natural questions for the reader to pose—as generations of readers and commentators attest. The questions are natural only in the sense that the text is constructed so as to prompt [End Page 578] them. Questions of historicity arise almost inevitably from the tension in the dramatic frame between, on the one hand, the repeated emphasis on the desire for accuracy, and, on the other hand, the strained relationship—elaborately indirect and distant both spatially and temporally—between the words of the text and the words of Socrates.A further, telling detail appears directly before Phaedo's narrative begins. In response to a question by Echecrates, Phaedo lists the friends of Socrates who were present. In the course of this list, Phaedo famously remarks, "I believe that Plato was ill" or perhaps better (Jowett) "but Plato, if I am not mistaken, was... (shrink)

This paper examines the outcomes of four Australian schools' efforts to promote greater collaboration between teachers in each school. Teachers' responses to questions about the nature and extent of collaboration they experienced at school revealed that teaming arrangements were in place in the four schools studied. Collaborative ways of working helped most teachers feel better about themselves and their work, and provided them with opportunities to learn from each other. However, a minority of teachers were negative about the new teaming (...) arrangements claiming that the changes had led to an increase in their workloads, a loss of professional autonomy, and the emergence of damaging competition between teams for resources, recognition and power. The paper concludes with a call for further micropolitical work that problematises apparently self evident ?goods? like teacher collaboration. (shrink)

Although the target article emphasizes the important role of prediction in language use, prediction may well also play a key role in the initial formation of linguistic representations, that is, in language development. We outline the role of prediction in three relevant language-learning domains: transitional probabilities, statistical preemption, and construction learning.

The UN Convention on the Rights of Persons with Disabilities (CRPD) was passed in 2006 and came into force in 2008. It sets out a number of core values, including dignity, individual autonomy, non-discrimination, participation and community inclusion. Although the CRPD has been recognised as an important step forward by many disabled people and their supporters and provides the foundation for building a good life, the author argues that it does not necessarily equate with it. The underpinning Western values of (...) choice, independence and control are important, but leave out groups of marginalised people for whom these goals may not be achievable. They also present challenges and dilemmas for those involved in supporting/caring roles. In this paper, the author reflects on the implications of the CRPD for the lives of people with learning disabilities, in particular those with profound needs and explores whether it provides a genuinely coherent framework for an inclusive society.

The aim of this article is to review and reconsider what scholars, including historians, archaeologists, and those in other disciplines, are trying to get at when they attempt a “social interpretation” of English late medieval domestic buildings. I focus on the definition and interpretation of “meaning,” and I examine critically a series of concepts routinely deployed in social interpretations in the past, including my own work, such as type, zeitgeist, and intention. I argue that some of these concepts and interpretive (...) moves are problematic and rather than aiding in our understanding, raise further questions in their turn about how buildings were lived in and understood by their medieval inhabitants. I argue for a shift in language and jargon away from “planning” and “meaning” to that of “lived experience”. I explore such a possible shift with reference to different understandings of and debates over the late medieval castle of Bodiam in southeastern England. Such a shift from meaning to lived experience raises fresh challenges for the development and empirical evaluation of interdisciplinary research on medieval buildings, but it also raises fresh possibilities and insights.

This paper shows how to define probability distributions over linguistically realistic syntactic structures in a way that permits us to define language learning and language comprehension as statistical problems. We demonstrate our approach using lexical‐functional grammar (LFG), but our approach generalizes to virtually any linguistic theory. Our probabilistic models are maximum entropy models. In this paper we concentrate on statistical inference procedures for learning the parameters that define these probability distributions. We point out some of the practical problems that make (...) straightforward ways of estimating these distributions infeasible, and develop a “pseudo‐likelihood” estimation procedure that overcomes some of these problems. This method raises interesting questions concerning the nature of the data available to a language learner and the modularity of language learning and processing. (shrink)

We hypothesize that juvenile baboons are less efficient foragers than adult baboons owing to their small size, lower level of knowledge and skill, and/or lesser ability to maintain access to resources. We predict that as resources are more difficult to extract, juvenile baboons will demonstrate lower efficiency than adults will because of their lower levels of experience. In addition, we hypothesize that juvenile baboons will be more likely to allocate foraging time to easier-to-extract resources owing to their greater efficiency in (...) acquiring those resources.We use feeding efficiency and time allocation data collected on a wild, free-ranging, non-provisioned population of chacma baboons (Papio hamadryas ursinus) in the Moremi Wildlife Reserve, Okavango Delta, Botswana to test these hypotheses. The major findings of this study are:1. Juvenile baboons are significantly less efficient foragers than adult baboons primarily for difficult-to-extract resources.We propose that this age-dependent variation in efficiency is due to differences in memory and other cognitive functions related to locating food resources, as is indicated by the greater amount of time juvenile baboons spend searching for food. There is no evidence that smaller body size or competitive disruption influences the differences in return rates found between adult and juvenile baboons in this study.2. An individual baboon’s feeding efficiency for a given resource can be used to predict the duration of its foraging bouts for that resource.These results contribute both to our understanding of the ontogeny of behavioral development in nonhuman primates, especially regarding foraging ability, and to current debate within the field of human behavioral ecology regarding the evolution of the juvenile period in primates and humans.

Scientists of the Human Genome Project tend to rely on three metaphors to describe their work, each of which implicitly tells much the same story. Whether they claim to interpret the ultimate "book," to fix a flawed "machine," or to map a mysterious "wilderness," they invariably cast the researcher as one who dominates and exploits the Other. This essay, which explores the ways such a story conflicts with feminist values, proposes an alternative.

We aim at developing a systematic method of separating omniscience principles by constructing Kripke models for intuitionistic predicate logic $\mathbf {IQC}$ and first-order arithmetic $\mathbf {HA}$ from a Kripke model for intuitionistic propositional logic $\mathbf {IPC}$. To this end, we introduce the notion of an extended frame, and show that each IPC-Kripke model generates an extended frame. By using the extended frame generated by an IPC-Kripke model, we give a separation theorem of a schema from a set of schemata in (...) $\mathbf {IQC}$ and a separation theorem of a sentence from a set of schemata in $\mathbf {HA}$. We see several examples which give us separations among omniscience principles. (shrink)

This article proposes an alternative approach in sustainability assessment. The conceptual framework was developed by modifying Ken Wilber's All Quadrants, All Levels (AQAL) approach, and focuses on the inter-relatedness/inter-connection of various perspectives inherent to the concept of sustainability. To look at how our framework can facilitate the practice of sustainability assessment, we apply the framework to examine the relationships between social systems and the environmental changes in the Ili River basin across the period 1900?2008. This approach enables us to investigate (...) the environmental problems of the Ili River basin in a four-quadrant framework, and combine the empirics of quadrants obtained from traditional disciplinary methodologies. The four-quadrant framework adopted in this study illustrates the interlocking relationships among various perspectives of environmental issues in the Ili River basin, namely, physical perspective, personal perspective, cultural perspective, and social perspective. In particular, the protruding development (evolution) of the lower right dimension is the fundamental cause of the environmental degradation and its related social problems in the Ili River basin. Compared to other established approaches in literature that emphasize on the tradeoffs of various perspectives of sustainability, our findings indicate the potential contributions of four-quadrant framework to sustainability assessment through its focus on the inter-relatedness/inter-connection of different perspectives.

B. F. Skinner is perhaps even more widely known for his views on science than for his experimental work. His comments on the role of theory in science have been labeled “anti-theoretical,” “ultra-empirical”, “non-theoretical,” “radical,” and worse. His position appears to be both extreme and untenable. Scriven [1] has given us a critique of Skinner that goes beyond mere labeling; it is an examination of the assumptions and implications of such a position.

Arthur Tansley first defined the term ecosystem in his seminal work “Use and Abuse of Vegetational Concepts,” as an improved way of viewing the relationships between plants and their physical environments. However, his definition, while widely influential, privileges the living components over nonliving components of ecosystems, and has thus been unable to fully overcome the biocentrism of early plant ecologists. Moreover, the binary between life and nonlife is untenable, and serves only as a marker of the underlying biocentric values of (...) a researcher. Drawing from Donna Haraway’s argument for situated knowledges, one can critically examine the biocentrism implicit in much of ecology, and reconsider our definition of ecosystem in order to highlight our devaluation of the nonliving, and expand our normative universe.

This essay surveys and assesses J. G. Merquior's principal English?language contributions to liberal social and political theory. The greatest strength of Merquior's work is his recognition that one can neither understand nor defend liberalism without first understanding and defending modernity. The greatest weakness of Merquior's work is his overly oppositional conception of the relationship between modernity and its postmodern critics, particularly his failure to recognize that both the positive and negative features of postmodernism are simply radicalizations of the positive and (...) negative features of modernity itself. It is argued that the strengths of Merquior's work are best affirmed and its weaknesses best overcome by appropriating it within the context of a ?critical modernist? approach to understanding and legitimizing the institutions and practices characteristic of modernity and liberalism.
