Making interactions between humans and artificial agents successful is a major goal of interaction design. The aim of this paper is to provide researchers conducting interaction studies a new framework for the evaluation of robot believability. By critically examining the ordinary sense of believability, we first argue that currently available notions of it are underspecified for rigorous application in an experimental setting. We then define four concepts that capture different senses of believability, each of which connects directly to an empirical (...) methodology. Finally, we show how this framework has been and can be used in the construction of interaction studies by applying it to our own work in human–robot interaction. (shrink)
We show how faceted search using a combination of traditional classification systems and mixed-membership topic models can go beyond keyword search to inform resource discovery, hypothesis formulation, and argument extraction for interdisciplinary research. Our test domain is the history and philosophy of scientific work on animal mind and cognition. The methods can be generalized to other research areas and ultimately support a system for semi-automatic identification of argument structures. We provide a case study for the application of the methods to (...) the problem of identifying and extracting arguments about anthropomorphism during a critical period in the development of comparative psychology. We show how a combination of classification systems and mixed-membership models trained over large digital libraries can inform resource discovery in this domain. Through a novel approach of “drill-down” topic modeling—simultaneously reducing both the size of the corpus and the unit of analysis—we are able to reduce a large collection of fulltext volumes to a much smaller set of pages within six focal volumes containing arguments of interest to historians and philosophers of comparative psychology. The volumes identified in this way did not appear among the first ten results of the keyword search in the HathiTrust digital library and the pages bear the kind of “close reading” needed to generate original interpretations that is the heart of scholarly work in the humanities. Zooming back out, we provide a way to place the books onto a map of science originally constructed from very different data and for different purposes. The multilevel approach advances understanding of the intellectual and societal contexts in which writings are interpreted. (shrink)
After years of relative neglect, experimental science has once again become an object of scrutiny. Philosophers such as Hacking and Cartwright have examined contemporary science in an attempt to display the epistemic status of experimental results, while sociologists such as Shapin and Schaffer have focussed on historical cases in an attempt to display the conventional basis of experimentation. In this study I am concerned with the epistemological question: How can one justify the claim that it is rational to believe that (...) the methods of experimental science yield knowledge about the unobserved causal structures of our world? My answer to this question is produced by way of an historical analysis and philosophical retrieval of Robert Boyle's epistemological defense of experimental science. ;The first two chapters examine contemporary issues surrounding experimental science, particularly those challenges posed to its knowledge-producing ability by philosophical instrumentalists and sociological constructionists. I then turn to an examination of Boyle's version of experimental philosophy, which includes a detailed discussion of the background traditions from which he drew in its formulation, and his response to critics of experimentation, such as Hobbes and Spinoza. ;Boyle's work is not only historically important, but is philosophically significant in light of the fact that he developed epistemological strategies in defense of experimental techniques at a time when it was not clear that experimentation would become the standard of modern science. His philosophy is characterized as a sophisticated and complex method that employs the elements of inductive, retroductive, and hypothetico-deductive reasoning. This combination, he argues, yields a system of checks and balances on sense, reason, and ideology that, while fallible, offers us the best assurance that we have of coming closer to the truth about the processes operative in our world. ;In a concluding chapter it is argued that Boyle's philosophy of science, by virtue of its richness and complexity, is sufficient to respond to the general challenges to scientific objectivity posed by sociologists of knowledge, and the more specific challenges to the realist import of the theoretical claims of experimental science posed by philosophers such as Laudan and van Fraassen.

Field-Programmable Gate Arrays have emerged as an attractive means of implementing logic circuits, providing instant manufacturing turnaround and negligible prototype costs. They hold the promise of replacing much of the VLSI market now held by mask-programmed gate arrays. FPGAs offer an affordable solution for customized VLSI, over a wide variety of applications, and have also opened up new possibilities in designing reconfigurable digital systems. Field-Programmable Gate Arrays discusses the most important aspects of FPGAs in a textbook manner. It provides the (...) reader with a focused view of the key issues, using a consistent notation and style of presentation. It provides detailed descriptions of commercially available FPGAs and an in-depth treatment of the FPGA architecture and CAD issues that are the subjects of current research. The material presented is of interest to a variety of readers, including those who are not familiar with FPGA technology, but wish to be introduced to it, as well as those who already have an understanding of FPGAs, but who are interested in learning about the research directions that are of current interest.

BackgroundThe COVID-19 crisis has introduced a variety of stressors, while simultaneously decreasing the availability of strategies to cope with stress. In this context, it could be useful to understand issues that people find most concerning and ways in which they cope with stress. In this study, we explored these questions with a sample of graduate and professional students.MethodUsing open-ended assessments, we asked participants to identify their biggest challenge or concern, their most effective way of handling stress, and their most common (...) way of handling stress. We applied thematic analysis and evaluated whether participants’ strategies corresponded with evidence-based practices.ResultsParticipants frequently reported top problems relating to productivity, physical health, and emotional health. Distraction was the most frequently classified common strategy, whereas behavioral activation was the most frequently identified effective strategy. Participants who reported a common strategy classified as an EBP reported lower depressive and anxiety symptoms. In contrast, there was no evidence of an association between symptom levels and whether or not participants’ effective strategy was an EBP. Participants who reported the same strategy as both their common and effective strategy reported lower depressive symptoms than those whose common and effective strategies were different.ConclusionOur findings highlight stressors that students are experiencing and ways they are coping during the COVID-19 crisis. We discuss how these findings can inform mental health promotion efforts and future research on coping with stressors. (shrink)
In her recent case study, Elizabeth Potter attempts to show how Boyle's experimental method was biased by gender considerations. Part of her argument focuses on the combination of the “invisibility” of women in Boyle's published work together with his unpublished comments on female chastity, and part concerns Boyle's rejection of the animistic explanation of his air pump experiments by Francis Line. I argue that the historical and biographical elements of the case make Potter's arguments questionable. In addition, I address whether (...) and how such historical cases can shed light on current debates about gender issues and argue that Boyle's methodological writings could be used to better advantage in the feminist cause.

Despite recent advances in HIV prevention and treatment, high HIV incidence persists among people who inject drugs. Difficult legal and political environments and lack of services for PWID likely contribute to high HIV incidence. Some advocates question whether any HIV prevention research is ethically justified in settings where healthcare system fails to provide basic services to PWID and where implementation of research findings is fraught with political barriers. Ethical challenges in research with PWID include concern about whether research evidence will (...) be translated into practice; concerns that research might exacerbate background risks; and ethical challenges regarding the standard of HIV prevention in research. While these questions arise in other research settings, for research with PWID, these questions are especially controversial. This paper analyses four ethical questions in determining whether research could be ethically acceptable: Can researchers ensure that research does not add to the burden of social harms and poor health experienced by PWID? Should research be conducted in settings where it is uncertain whether research findings will be translated into practice? When best practices in prevention and care are not locally available, what standard of care and prevention is ethically appropriate? Does the conduct of research in settings with oppressive policies constitute complicity? We outline specific criteria to address these four ethical challenges. We also urge researchers to join the call to action for policy change to provide proven safe and effective HIV prevention and harm reduction interventions for PWID around the world. (shrink)

We discuss several issues raised by Caplan & Waters's distinction between interpretative and post-interpretative processes in sentence comprehension, including the nature and properties of the two systems, problems with measuring their respective capacities, and the relationship between the hypothesized separate-language-interpretation-resource (SLIR) and the general verbal working memory system that supports post-interpretive processing.
Michael Howard begins with quick sketches of the travesties that show the crisis of global capitalism and then introduces the book’s comprehensive study showing the fertile seeds of socialism. The only suggestion of a perceived crisis of socialism is in the title and in a few sentences in the introduction about crises of identity on the left and about crises of “principles, institutions, and practices”, of socialism, the themes of the three parts of this wide-ranging book. The extensive discussion of (...) socialist ideas and experiments suggests that the only crisis is that capitalism is global, the challenge in the background. (shrink)

We take this opportunity to respond to the excellent points raised by the commentators. All of the commentaries support our emphasis on robust community engagement with PWID and other stakeholders in designing and conducting HIV prevention research, but urge us to go farther. Wolfe highlights the difficulty of even engaging with community members in oppressive settings, where authorities severely restrict civil liberties of PWID so that even discussing issues related to drug use and enforcement may place individuals at risk. To overcome such limitations, he appropriately suggests interviewing confidentially those who have previously been detained in closed settings as part of the community engagement process. Similarly, Wolfe observes that critical issues can be overlooked with a narrow focus on study procedures if contextual factors before, during or after a study are ignored. For example, he cites the risk of overdose for study participants who have been abstinent during a study and subsequently resume injecting when the study concludes. These kinds of risks may not be obvious …. (shrink)
Rose's accomplishment in combining ontological unity with epistemological diversity contrasts it with Wilson's failure in overemphasizing the former and not appreciating the latter. This commentary cites the two most authoritative discussions of the inapplicability of heritability to human data, corrects several historical errors or inaccuracies in genetics, and criticizes the characterizations of Jacques Loeb and Robert Plomin.
Early last year, the GenEthics Consortium (GEC) of the Washington Metropolitan Area convened at George Washington University to consider a complex case about genetic testing for Alzheimer disease (AD). The GEC consists of scientists, bioethicists, lawyers, genetic counselors, and consumers from a variety of institutions and affiliations. Four of the 8 co-authors of this paper delivered presentations on the case. Supplemented by additional ethical and legal observations, these presentations form the basis for the following discussion.
As interest in working memory is increasing at a rapid pace, an open discussion of the central issues involved is both useful and timely. This new volume compares and contrasts conceptions of working memory, with contributions from proponents of different views.
The COVID-19 outbreak has simultaneously increased the need for mental health services and decreased their availability. Brief online self-help interventions that can be completed in a single session could be especially helpful in improving access to care during the crisis. However, little is known about the uptake, acceptability, and perceived utility of these interventions outside of clinical trials in which participants are compensated. Here, we describe the development, deployment, acceptability ratings, and pre–post effects of a single-session intervention, the Common Elements (...) Toolbox, adapted for the COVID-19 crisis to support graduate and professional students. Participants, who were not compensated, were randomly assigned to two of three modules: behavioral activation, cognitive restructuring, and gratitude. Over 1 week, 263 individuals began and 189 individuals completed the intervention. Participants reported that the intervention modules were acceptable, helpful, engaging, applicable to their lives, and could help them manage COVID-related challenges. Participants reported pre- to post-program improvements in secondary control and in the perceived negative impact of the COVID-19 crisis on their quality of life. On average, differences in their perceived ability to handle lifestyle changes resulting from the pandemic were positive, but small and at the level of a non-significant trend. Our results highlight the acceptability and utility of an online intervention for supporting individuals through the COVID-19 crisis. (shrink)
Gillian Rose was a philosopher, social theorist, memoirist, and Jewish convert to Christianity who died an untimely death in 1995. She offers a novel account of faith, which grows out of her Hegelian philosophical background inflected by her reading of Kierkegaard and her rediscovered Jewish heritage. For Rose, faith is a mode of social practice. Rose's conception of faith is here reconstructed by translating her obscure jurisprudential idiom into the language of social practices and norms. The conception (...) of secular faith developed by Rose is shown to have implications for contemporary discussions of ethics and politics. The contemporary relevance of Rose's work is made clear through comparison with recent work by Robert Brandom, Robert Adams, and Patrick Deneen. (shrink)
