Substantivalists claim that spacetime enjoys an existence analogous to that of material bodies, while relationalists seek to reduce spacetime to sets of possible spatiotemporal relations. The resulting debate has been central to the philosophy of space and time since the Scientific Revolution. Recently, many philosophers of physics have turned away from the debate, claiming that it is no longer of any relevance to physics. At the same time, there has been renewed interest in the debate among physicists working on quantum (...) gravity, who claim that the conceptual problems which they face are intimately related to interpretative questions concerning general relativity . My goal is to show that the physicists are correct--there is a close relationship between the interpretative issues of classical and quantum gravity. ;In the first part of the dissertation I challenge the received view that substantivalism has a commanding advantage over relationalism on grounds internal to GR. I argue that this view is based on a misconception of the relationships between realism and substantivalism, and between empiricism and relationalism. This has led to a narrow conception of relationalism. Once this is relinquished it can be seen that none of the standard arguments in favor of substantivalism are cogent. ;In the second part of the dissertation, I consider the way in which considerations arising out of quantum gravity bear upon the substantival-relational debate. I develop a framework in which to discuss the interpretative problems of gauge theories and place GR in this context. From this perspective, I provide a taxonomy of interpretative options, and show how the hole argument arises naturally as a consequence of gauge freedom. This means that certain substantivalist interpretations of GR render the theory indeterministic. In the final chapter, I argue that, far from being a drawback, this presents an opportunity for substantivalists. Examples from quantum mechanics, quantum field theory, and quantum gravity, are used to demonstrate that the ambiguities inherent in quantization can lead to an interpretative interplay between theories. In the case of quantum gravity, this means that substantivalism and relationalism suggest, and are suggested by, distinct approaches to quantizing GR. (shrink)

Scott Gordon provides a magisterial review of the historical development of the social sciences from their beginnings in renaissance Italy to the present day.

Challenging recent work that contends that seventeenth-century English discourses privilege the notion of a self-enclosed, self-sufficient individual, The Power of the Passive Self in English Literature recovers a counter-tradition that imagines selves as more passively prompted than actively choosing. This tradition - which Scott Paul Gordon locates in seventeenth-century religious discourse, in early eighteenth-century moral philosophy, in mid eighteenth-century acting theory, and in the emergent novel - resists autonomy and defers agency from the individual to an external 'prompter'. (...) Gordon argues that the trope of passivity aims to guarantee a disinterested self in a culture that was increasingly convinced that every deliberate action involves calculating one's own interest. Gordon traces the origins of such ideas from their roots in the non-conformist religious tradition to their flowering in one of the central texts of eighteenth-century literature, Samuel Richardson's Clarissa.

This paper shows how the critical questions matching an argumentation scheme can be mod-eled in the Carneades argumentation system as three kinds of premises. Ordinary premises hold only if they are supported by sufficient arguments. Assumptions hold, by default, until they have been questioned. With exceptions the negation holds, by default, until the exception has been supported by sufficient arguments. By “sufficient arguments”, we mean arguments sufficient to satisfy the applicable proof standard.

The main theme of these lectures is man's struggle to understand himself as a social being. A discussion of the major problems confronting man in his attempts to come to grips with the modern social world ends with a plea for liberalism and rationalism as the political and intellectual foundations of freedom and progress.

It seems to me that no substantial support can be provided for the thesis that the Darwinian theory of evolution drew significantly upon ideas in contemporary Political Economy. What Darwin may have derived from Malthus was not an integral part of the theory of population that the classical economists, including Malthus, put forward. He did not know the literature of Political Economy; and if he had been acquainted with it, he would not have been able to derive anything from it (...) that was important for the theory of natural selection. The judgment that “with Darwin's theory there was a real transfer of knowledge from political economy to biology” (Pancaldi 1985:262) cannot be sustained. (shrink)

Undergraduate projects may contribute new knowledge, but commonly their main purpose is an exercise in learning and applying simple research methods. They are usually short term and a first step into the research field. Support for undergraduate research experience is simple enough. However, integral to the research process is ethical scrutiny. A high standard of conduct of research is essential. The question of whether undergraduate student projects should be subject to full ethical review, to the same extent as that undertaken (...) for full scale academic work, is a matter of debate. The purpose of this study was to explore the views of academics on the nature and extent of ethical review considered appropriate for undergraduate research projects. This was done in order to identify which side of the above debate was favoured. Participants were undergraduate research project supervisors, drawn from a range of disciplines where research on human subjects is undertaken. A series of focus groups were undertaken, transcribed and subjected to thematic analysis. There was general consensus that some consideration should be given to the ethical issues relating to student projects. However, participants were limited in their explicit identification of such issues, with only extreme examples being specifically described. Some favoured a ‘light touch’ proportional to the size of the project as appropriate, while others considered the level ethical scrutiny not related to the size, duration or outcome of the work. Opinions were divided on where responsibility ultimately lay. Some considered it to belong at departmental, faculty or institutional level, but others held the individual supervisor accountable. The degree of involvement of undergraduate research in ethical review and approval is clearly an issue amongst academics. This study helps raise awareness of these issues and promotes debate on the appropriate level and format of review needed for undergraduate research training. (shrink)

Background: Facial attractiveness influences our perceptions of others, with beautiful faces reaping societal rewards and anomalous faces encountering penalties. The purpose of this study was to determine associations of visual attention with bias and social dispositions toward people with facial anomalies. -/- Methods: Sixty subjects completed tests evaluating implicit bias, explicit bias, and social dispositions before viewing publicly available images of preoperative and postoperative patients with hemifacial microsomia. Eye-tracking was used to register visual fixations. -/- Results: Participants with higher implicit (...) bias scores fixated significantly less on the cheek and ear region preoperatively (P = 0.004). Participants with higher scores in empathic concern and perspective taking fixated more on the forehead and orbit preoperatively (P = 0.045) and nose and lips (P = 0.027) preoperativel. -/- Conclusions: Participants with higher levels of implicit bias spent less visual attention on anomalous facial anatomy, whereas participants with higher levels of empathic concern and perspective taking spent more visual attention on normal facial anatomy. Levels of bias and social dispositions such as empathy may predict layperson gaze patterns toward those with facial anomalies and provide insights to neural mechanisms underlying the "anomalous is bad" paradigm.

Background: Facial proportionality and symmetry are positively associated with perceived levels of facial attractiveness. -/- Objective: The aims of this study were to confirm and extend the association of proportionality with perceived levels of attractiveness and character traits and determine differences in attractiveness and character ratings between "anomalous" and "typical" faces using a large dataset. -/- Methods: Ratings of 597 unique individuals from the Chicago Face Database were used. A formula was developed as a proxy of relative horizontal proportionality, where (...) a proportionality score of "0" indicated perfect proportionality and more negative scores indicated less proportionality. Faces were categorized as "anomalous" or "typical" by 2 independent reviewers based on physical features. -/- Results: Across the ratings for all faces, Spearman correlations revealed greater proportionality was associated with attractiveness ( ρ = 0.292, P < 0.001) and trustworthiness ( ρ = 0.193, P < 0.001), while lesser proportionality was associated with impressions of anger (ρ = 0.132, P = 0.001), dominance (ρ = 0.259, P < 0.001), and threateningness ( ρ = 0.234, P < 0.001). Mann-Whitney U tests revealed the typical cohort had significantly higher levels of proportionality (-13.98 versus -15.14, P = 0.030) and ratings of attractiveness (3.39 versus 2.99, P < 0.001) and trustworthiness (3.48 versus 3.35, P < 0.001). -/- Conclusions: This study demonstrated that facial proportionality is not only significantly associated with higher ratings of attractiveness, but also associated with judgements of trustworthiness. Proportionality plays a role in evoking negative attributions of personality characteristics to people with facial anomalies. (shrink)

This three-part paper presents Gordon Pask’s conversation theory (CT) and interaction of actors theory (IA) and outlines ways to apply these cybernetic approaches to designing technologies and scenarios for both formal and informal learning. The first part of the paper covers concepts central to CT and IA, explaining the relationship between conceptual and mechanical operators, and machines mediating informal and formal learning. The second part of the paper applies visual representations of CT and IA to understanding the use of (...) Pask’s course assembly systems (CASTE and THOUGHTSTICKER), created between the late 1960s and the 1980s, and the ThoughtShuffler search interface, created in the 2010s. The third part proposes two pathways for design based on CT and IA: firstly, the potential for designers and observers to reformulate the qualities of tools and learning scenarios to augment human thinking and collective action; and secondly, the possibility to create tools with malleable interfaces that allow users to become intermediaries rather than consumers of knowledge.

BackgroundKinarm Standard Tests is a suite of upper limb tasks to assess sensory, motor, and cognitive functions, which produces granular performance data that reflect spatial and temporal aspects of behavior. We have previously used principal component analysis to reduce the dimensionality of multivariate data using the Kinarm End-Point Lab. Here, we performed PCA using data from the Kinarm Exoskeleton Lab, and determined agreement of PCA results across EP and EXO platforms in healthy participants. We additionally examined whether further dimensionality reduction (...) was possible by using PCA across behavioral tasks.MethodsHealthy participants were assessed using the Kinarm EXO and EP. Four behavioral tasks were performed that quantified arm sensory and motor function, including position sense [Arm Position Matching ] and three motor tasks [Visually Guided Reaching, Object Hit, and Object Hit and Avoid ]. The number of components to include per task was determined from scree plots and parallel analysis, and rotation type was decided on a per-task basis. To assess agreement, we compared principal components across platforms using distance correlation. We additionally considered inter-task interactions in EXO data by performing PCA across all six behavioral assessments.ResultsBy applying PCA on a per task basis to data collected using the EXO, the number of behavioral parameters were substantially reduced by 58–75% while accounting for 76–87% of the variance. These results compared well to the EP analysis, and we found good-to-excellent agreement values between PCs from the EXO and those from the EP. Finally, we were able to reduce the dimensionality of the EXO data across tasks down to 16 components out of a total of 76 behavioral parameters, which represents a reduction of 79% while accounting for 73% of the total variance.ConclusionPCA of Kinarm robotic assessment appears to capture similar relationships between kinematic features in healthy individuals and is agnostic to the robotic platform used for collection. Further work is needed to investigate the use of PCA-based data reduction for the characterization of neurological deficits in clinical populations. (shrink)

Lower plasma levels of high-density lipoproteins in adolescents with type 2 diabetes have been associated with a higher pulse wave velocity, a marker of arterial stiffness. Evidence suggests that HDL proteins or particle subspecies are altered in T2D and these may drive these relationships. In this work, we set out to reveal any specific proteins and subspecies that are related to arterial stiffness in youth with T2D from proteomics data. Plasma and PWV measurements were previously acquired from lean and T2D (...) adolescents. Each plasma sample was separated into 18 fractions and evaluated by mass spectrometry. Then, we applied a validated network-based computational approach to reveal HDL subspecies associated with PWV. Among 68 detected phospholipid-associated proteins, we found that seven were negatively correlated with PWV, indicating that they may be atheroprotective. Conversely, nine proteins show positive correlation with PWV, suggesting that they may be related to arterial stiffness. Intriguingly, our results demonstrate that apoA-I and histidine-rich glycoprotein may reverse their protective roles and become antagonistic in the setting of T2D. Furthermore, we revealed two arterial stiffness-associated HDL subspecies, each of which contains multiple PWV-related proteins. Correlation and disease association analyses suggest that these HDL subspecies might link T2D to its cardiovascular-related complications. (shrink)

Past research has examined the ethical judgments of consumers in the U.S., but few studies have investigated such attitudes in foreign-market settings. The current study compares ethical attitudes of consumers in two countries (Ireland and Lebanon) which share a cultural similarity of ongoing war and terrorism. The findings reveal that both cultures exhibit low sensitivity to ethical issues. Furthermore, the findings show that the Irish consumers are less sensitive to consumer ethical practices, less idealistic, more relativistic, and more Machiavellian than (...) Lebanese consumers. The authors recommend that other researchers need to further investigate this perplexing issue because ethics is a research topic which often discourages survey respondents to be candid. (shrink)

The study of anarchism as a philosophical, political, and social movement has burgeoned both in the academy and in the global activist community in recent years. Taking advantage of this boom in anarchist scholarship, Nathan J. Jun and Shane Wahl have compiled twenty-six cutting-edge essays on this timely topic in New Perspectives on Anarchism.

Open peer commentary on the article “Luhmann and the Constructivist Heritage: A Critical Reflection” by Eva Buchinger. Upshot: I acknowledge the value of Buchinger’s contribution to my understanding of Luhmann’s theory of social systems and seek some clarification and elaboration concerning specific issues. In particular, I raise some questions about the concepts of meaning processing and of psychic systems and persons, with reference to related ideas developed by Gordon Pask and myself. I also question how Luhmann uses the term (...) “autopoiesis.”. (shrink)

BackgroundPeople with upper extremity amputations report receiving insufficient information about treatment options. Furthermore, patients commonly report not knowing what questions to ask providers. A question prompt sheet, or list of questions, can support patient-centered care by empowering patients to ask questions important to them, promoting patient-provider communication, and increasing patient knowledge. This study assessed information needs among people with UE amputations about UE vascularized composite allotransplantation and developed a UE VCA-QPS.MethodsThis multi-site, cross-sectional, mixed-methods study involved in-depth and semi-structured interviews with (...) people with UE amputations to assess information needs and develop a UE VCA-QPS. Qualitative data were analyzed by thematic analysis; quantitative data were analyzed by descriptive statistics. The initial UE VCA-QPS included 130 items across 18 topics.ResultsEighty-nine people with UE amputations participated. Most were male, had a mean age of 46 years, and had a unilateral and below-elbow amputation. Participants desired information about UE VCA eligibility, evaluation process, surgery, risks, rehabilitation, and functional outcomes. After refinement, the final UE VCA-QPS included 35 items, across 9 topics. All items were written at a ≤ 6th grade reading level. Most semi-structured interview participants reported being ‘completely’ or ‘very’ likely to use a UE VCA-QPS.ConclusionPeople with UE amputations have extensive information needs about UE VCA. The UE VCA-QPS aims to address patients’ information needs and foster patient-centered care. Future research should assess whether the UE VCA-QPS facilitates patient-provider discussion and informed decision-making for UE VCA. (shrink)

Purpose: Gordon Pask has left behind a voluminous scientific oeuvre in which he frequently uses technical language and a detail of argument that makes his work difficult to access except by the most dedicated of students. His ideas have also evolved over a long period. This paper provides introductions to three of Pask's key concepts: "conversations," "individuals," and "concepts." Method: Based on the author's close knowledge of Pask's work, as his collaborator for ten years and as someone who has (...) had access to and is familiar with almost all of his published work, the paper selects three of Pask's key concepts for elucidation in order to motivate the interested reader to explore Pask's work in the original. Results: Pask's key concepts, "conversations," "individuals," and "concepts," which are central in his conversation theory and his later elaborations in "interaction of actors theory," are shown to be grounded in fundamental principles from cybernetics. Furthermore, the form of Pask's theorising is that of second order (reflexive) metatheorising, developing theories of theorising that explain their own form and genesis. (shrink)

Although it is conceded that distinct knowledge domains do presentparticular problems of coming to know, in thispaper it is argued that it is possible to construct a domain independent modelof the processes of coming to know, one inwhich observers share understandings and do soin agreed ways. The model in question is partof the conversation theory of Gordon Pask. CT, as a theory of theory construction andcommunication, has particular relevance forfoundational issues in science and scienceeducation. CT explicitly propounds a ``radicalconstructivist'' (...) epistemology. A briefaccount is given of the main tenets of RC andCT's place in that tradition and the traditionsof cybernetics. The paper presents a briefnon-technical account of the main concepts ofCT including elaborations by Laurillard andHarri-Augstein and Thomas. As part of CT, Pask also elaborated a methodology – knowledgeand task analysis – for analysing the structureof different knowledge domains; thismethodology is sketched in outline. (shrink)

Ender’s Game, Orson Scott Card’s award-winning 1985 novel, has been discovered and rediscovered by generations of science fiction fans, even being adopted as reading by the U.S. Marine Corps. Ender's Game and its sequels explore rich themes — the violence and cruelty of children, the role of empathy in war, and the balance of individual dignity and the social good — with compelling elements of a coming-of-age story. Ender’s Game and Philosophy brings together over 30 philosophers to engage in (...) wide-ranging discussion on issues such as: the justifiability of pre-emptive strikes; how Ender’s disconnected and dispassionate violence is mirrored in today’s drone warfare; whether the end of saving the species can justify the most brutal means; the justifiability of lies and deception in wartime, and how military schools produce training in virtue. The authors of Ender’s Game and Philosophy challenge readers to confront the challenges that Ender’s Game presents, bringing new insights to the idea of a just war, the virtues of the soldier, the nature of childhood, and the serious work of playing games.

This workshop unearths the potential of applying principles of cybernetics to curriculum and educational technology design. Here, we focus on using technology-assisted learning scenarios at the confluence of education, psychology, and computer science as an asset for adults to learn the skills for critical Internet navigation; skills we argue are an integral part of life in the Information Age. The first part of the workshop begins with an introduction to what von Foerster called Gordon Pask’s first theorem (a basic (...) framework of human-tool conversations), which was used to design classes in heuristics at the University of Illinois, Urbana, and involved project-based community and artefact development. It then describes how this approach was replicated to co-design educational psychology classes at The Ohio State University in 2022-2023 to help preservice teachers engage in metareflection about their future careers. A small group discussion between workshop participants follows to understand how tools and activities used in these classes (social media, block programming, co-authoring, podcasting) can be adapted for other subject classrooms. The second part of the workshop focuses on fine-tuning the build of educational technologies like search engines to spur concept development. -/- We invite volunteers to interact with our Paskian search engine, ThoughtShuffler, which uses an uncertainty regulation mechanism to organize search results for lateral reading, and present results from an experimental study showing the tool has the potential to engender higher-order reflectivity in information search. We suggest principles of cybernetics can be used to co-design sociotechnical systems and sharpen both human and machine functioning within them, presenting hopes for human adaptation to an information-saturated future.

The Structure of Emotions argues that emotion concepts should have a much more important role in the social and behavioural sciences than they now enjoy, and shows that certain influential psychological theories of emotions overlook the explanatory power of our emotion concepts. Professor Gordon also outlines a new account of the nature of commonsense (or ‘folk’) psychology in general.

Anthropological inquiry suggests that all societies classify animals and plants in similar ways. Paradoxically, in the same cultures that have seen large advances in biological science, citizenry's practical knowledge of nature has dramatically diminished. Here we describe historical, cross-cultural and developmental research on how people ordinarily conceptualize organic nature, concentrating on cognitive consequences associated with knowledge devolution. We show that results on psychological studies of categorization and reasoning from “standard populations” fail to generalize to humanity at large. Usual populations have (...) impoverished experience with nature, which yields misleading results about knowledge acquisition and the ontogenetic relationship between folkbiology and folkpsychology. We also show that groups living in the same habitat can manifest strikingly distinct behaviors, cognitions and social relations relative to it. This has novel implications for environmental decision making and management, including commons problems. (shrink)

What follows is a discussion of three sets of experimental results that deal with various aspects of universal biological understanding among American and Maya children and adults. The first set of experiments shows that by the age of four-to-five years urban American and Yukatek Maya children employ a concept of innate species potential, or underlying essence, as an inferential framework for understanding the affiliation of an organism to a biological species, and for projecting known and unknown biological properties to organisms (...) in the face of uncertainty. The second set of experiments shows that the youngest Maya children do not have an anthropocentric understanding of the biological world. Children do not initially need to reason about non-human living kinds by analogy to human kinds. The third set of results show that the same taxonomic rank is cognitively preferred for biological induction in two diverse populations: people raised in the Mid-western USA and Itza' Maya of the Lowland Meso-american rainforest. This is the generic species  the level of oak and robin. These findings cannot be explained by domain-general models of similarity because such models cannot account for why both cultures prefer species-like groups in making inferences about the biological world, although Americans have relatively little actual knowledge or experience at this level. The implication from these experiments is that folk biology may well represent an evolutionary design: universal taxonomic structures, centred on essence-based generic species, are arguably routine products of our ‘habits of mind,' which may be in part naturally selected to grasp relevant and recurrent ‘habits of the world.' The science of biology is built upon these domain-specific cognitive universals: folk biology sets initial cognitive constraints on the development of any possible macro-biological theory, including the initial development of evolutionary theory. Nevertheless, the conditions of relevance under which science operates diverge from those pertinent to folk biology. For natural science, the motivating idea is to understand nature as it is ‘in itself,' independently of the human observer. From this standpoint, the species-concept, like taxonomy and teleology, may arguably be allowed to survive in science as a regulative principle that enables the mind to readily establish stable contact with the surrounding environment, rather than as an epistemic concept that guides the search for truth.

Global poverty measurement is important. It is used to allocate scarce resources, evaluate progress, and assess existing projects, policies, and institutional designs. But given the diversity of ways in which poverty is conceived, how can we settle on a conception and measure that can be used for interpersonal and inter-temporal global comparison? -/- This book lays out the key contemporary debates in poverty measurement, and provides a new analytical framework for thinking about poverty conception and measurement. Rather than trying to (...) find some essential meaning of poverty, the author recommends explicitly reflecting on the purposes served by the concept and the values that do and should inform our conceptions and measures. -/- After reviewing the strengths and weaknesses of five competing conceptions of poverty and their corresponding measures, the book concludes with specific recommendations for the future. Poverty measurement should be developed through a process of public reason that gives weight to the voices of those individuals who are most marginalized and deprived. The author suggests new values, desiderata, and candidate indicators that should be used in a pro-poor poverty measure. (shrink)

This is a book about the pragmatics of reference. When we communicate through language we inevitably talk about things. Those things might be people, places or objects, or they might be thoughts, ideas, emotions or abstract concepts. To talk about things, we need to refer to things, and this book is about how we refer to things.
