It is widely assumed that informing prospective subjects about the risks and possible benefits of research not only protects their rights as autonomous decisionmakers, but also empowers them to protect their own interests. Yet interviews with patient‐subjects conducted under the auspices of the Advisory Committee on Human Radiation Experiments suggest this is not always the case. Patient‐subjects often trust their physician to guide them through decisions on research participation. Clinicians, investigators, and IRBs must assure that such trust is not misplaced.

This qualitative study presents 27 students’ insights about four teachers’ implementation of an immersive Native American history curricular unit designed to equip students with digital skills to critically navigate complex, polarizing social issues. The Digital Civic Learning (DCL) curriculum used Google Suite and Google Classroom or Schoology to provide collaborative slides supporting immersive 2D-graphics, children’s books/resources, immersive activities/artefact-creation, and multimodal tools (e.g., discussion posts, Flipgrid video-essays). Teachers regulated student thinking/behavior towards cohesive outcomes, and encouraged open-ended exploration, operationalizing the design framework (...) as a zone of proximal development (ZPD). The history unit incorporates four cybernetic design features (DF) that enable teachers to steer student-centered collaboration within the curricular unit. The teacher serves four diverse roles (guide, facilitator, modeler, participant observer) mapping onto the DF. Results of focus group interviews with students, which were analyzed based on a theory-informed coding scheme and narrative inquiry, suggest ways for social studies teachers to operationalize the DCL immersive history unit as a cybernetic ZPD by adapting its basic structure to technologies accessible in their schools by adapting its basic structure to technologies accessible in their schools.

In the Reality we know, we cannot say if something is infinite whether we are doing Physics, Biology, Sociology or Economics. This means we have to be careful using this concept. Infinite structures do not exist in the physical world as far as we know. So what do mathematicians mean when they assert the existence of ω? There is no universally accepted philosophy of mathematics but the most common belief is that mathematics touches on another worldly absolute truth. Many mathematicians (...) believe that mathematics involves a special perception of an idealized world of absolute truth. This comes in part from the recognition that our knowledge of the physical world is imperfect and falls short of what we can apprehend with mathematical thinking. The objective of this paper is to present an epistemological rather than an historical vision of the mathematical concept of infinity that examines the dialectic between the actual and potential infinity.

The distribution of cultural variants in a population is shaped by both neutral evolutionary dynamics and by selection pressures. The temporal dynamics of social network connectivity, that is, the order in which individuals in a population interact with each other, has been largely unexplored. In this paper, we investigate how, in a fully connected social network, connectivity dynamics, alone and in interaction with different cognitive biases, affect the evolution of cultural variants. Using agent‐based computer simulations, we manipulate population connectivity dynamics (...) (early, mid, and late full‐population connectivity); content bias, or a preference for high‐quality variants; coordination bias, or whether agents tend to use self‐produced variants (egocentric bias), or to switch to variants observed in others (allocentric bias); and memory size, or the number of items that agents can store in their memory. We show that connectivity dynamics affect the time‐course of variant spread, with lower connectivity slowing down convergence of the population onto a single cultural variant. We also show that, compared to a neutral evolutionary model, content bias accelerates convergence and amplifies the effects of connectivity dynamics, while larger memory size and coordination bias, especially egocentric bias, slow down convergence. Furthermore, connectivity dynamics affect the frequency of high‐quality variants (adaptiveness), with late connectivity populations showing bursts of rapid change in adaptiveness followed by periods of relatively slower change, and early connectivity populations following a single‐peak evolutionary dynamic. We evaluate our simulations against existing data collected from previous experiments and show how our model reproduces the empirical patterns of convergence. (shrink)

Through cultural transmission, repeated learning by new individuals transforms cultural information, which tends to become increasingly compressible . Existing diffusion chain studies include in their design two processes that could be responsible for this tendency: learning and reproducing . This paper manipulates the presence of learning in a simple iterated drawing design experiment. We find that learning seems to be the causal factor behind the increase in compressibility observed in the transmitted information, while reproducing is a source of random heritable (...) innovations. Only a theory invoking these two aspects of cultural learning will be able to explain human culture's fundamental balance between stability and innovation. (shrink)

Binge-purge eating disorders (BP-ED), such as bulimia nervosa and binge eating disorder, may share some neurobiological features. Electroencephalography (EEG) is a non-invasive measurement modality that may aid in research and diagnosis of BP-ED. We conducted a systematic review of the literature on EEG findings in BP-ED, seeking to summarize and analyze the current evidence, as well as identify shortcomings and gaps to inform new perspectives for future studies. Following PRISMA Statement recommendations, the PubMed, Embase, and Web of Science databases were (...) searched using terms related to “electroencephalography” and “binge-purge” eating disorders. Of 555 articles retrieved, 15 met predefined inclusion criteria and were included for full-text analysis. Eleven studies investigated EEG by means of event-related potentials (ERP) in BP-ED individuals: 7 using eating disorder-related stimuli (i.e., food, body image) and 4 using non-eating disorder-related stimuli (i.e., facial expressions or auditory clicks). These studies found significant differences in the N200, P200, P300, and LPP components in BP-ED participants compared to controls, indicating that this population exhibits impairments in selective attention, attentional allocation/processing, and allocation of motivational or emotion-based attention. Five studies investigated EEG using frequency analysis; reporting significant differences in beta activity in fronto-temporal and occipito-temporo-parietal areas in BP-ED individuals compared to controls, revealing a dysfunctional brain network. However, the small number of studies, the heterogeneity of samples, study paradigms, stimulus types, and the lack of an adequate assessment of neuropsychological parameters are some limitations of the current literature. Although some EEG data are promising and consistent with neuroimaging and neuropsychological findings in individuals with BP-ED, future studies need to overcome current methodological shortcomings.

Recent studies have shown that making accurate passage of time judgments (POTJs) for long-time intervals is an important cognitive ability. Different temporal domains, such as circadian typology (biological time) and time perspective (psychological time), could have an effect on subjective POTJs, but few studies have investigated the reciprocal influences among these temporal domains. The present study is the first systematic attempt to fill this gap. A sample of 222 participants (53.20% females; 19–60 years) filled in the Zimbardo Time Perspective Inventory (...) for the measurement of time perspective, the reduced version of the Morningness-Eveningness Questionnaire (rMEQ) for chronotypes, and an ad-hoc questionnaire assessing sleep habits during weekdays and the weekend (for social jetlag). The POTJ was measured using a modified version of a pictorial timeline presented at five different moments. Also, participants judged how different temporal expressions were related to the past, present, and future along a 7-point Likert scale. After confirming the association between eveningness and present-hedonism orientation and morningness and future-orientation, we found that evening-types produced higher scores for future expressions. The subjective POTJ expressed in minutes was predicted by Deviation from Balanced Time (DBTP), present-fatalism orientation, and social jetlag. Finally, the rMEQ score, past-positive orientation, and DBTP predicted the difference between subjective and objective POT. The results are discussed offering an explanation in terms of the interconnections between circadian typology, individual time perspective, and the sense of the POT, suggesting the multicomponent nature of the concept of time.

A trenchant and wide-ranging look at this alarming national trend, _Disrupting the School-to-Prison Pipeline_ is unsparing in its account of the problem while pointing in the direction of meaningful and much-needed reforms. The “school-to-prison pipeline” has received much attention in the education world over the past few years. A fast-growing and disturbing development, it describes a range of circumstances whereby “children are funneled out of public schools and into the juvenile and criminal justice systems.” Scholars, educators, parents, students, and organizers (...) across the country have pointed to this shocking trend, insisting that it be identified and understood—and that it be addressed as an urgent matter by the larger community. This new volume from the _Harvard Educational Review _features essays from scholars, educators, students, and community activists who are working to disrupt, reverse, and redirect the pipeline. Alongside these authors are contributions from the people most affected: youth and adults who have been incarcerated, or whose lives have been shaped by the school-to-prison pipeline. Through stories, essays, and poems, these individuals add to the book’s comprehensive portrait of how our education and justice systems function—and how they fail to serve the interests of many young people.".

In early March 2014, some of the members of Culture on the Edge—a scholarly research collaboration of seven scholars of religion, interested in more theoretically sophisticated studies of identity, and all of whom are at different career stages and at a variety of North American institutions—had a conversation online on the use of the terms “critique” and “critical,” terms widely used in the field today but employed in such a variety of ways that the members of the group thought it (...) worthwhile to focus some attention on them.

The promise of genomic medicine lies in the opportunity to improve health outcomes via a personalized approach to management, grounded in genetic and genomic variation unique to an individual. However, disparities and inequities mar this remarkable landscape of genomic innovation. Prior efforts to understand these inequities have focused on populations for which genetic testing is relatively protocolized or where test utility varies greatly by ancestry groups, where equitable outcomes are more clearly defined. We therefore consider the current landscape of rare (...) disease genomics, in which diagnostic approaches vary widely and utility remains to be fully understood, and suggest a path forward: how ecosocial theory may be used to guide novel equity‐focused initiatives that incorporate illness narratives to improve population health. We present examples of narrative medicine in rare disease and reimagine the role this discipline may play in genomic sequencing studies, toward incorporation of the unique illness narrative into clinical genetics and genomics practice. Approaches that broaden the definitions of disease and of outcomes of interest will force the field to grapple with its racist history and begin to advance health equity and promote justice so that genomic medicine may truly deliver on its promise.

Influential theories on moral judgments propose that they rely either on emotions or on innate moral principles. In contrast, the mental model theory postulates that moral judgments rely on reasoning, either intuition or deliberation. The theory allows for the possibility that intuitions lead to utilitarian judgments. This paper reports two experiments involving fifth-grade children, adolescents, and adults; the results revealed that children reason intuitively to resolve moral dilemmas in which action and inaction lead to different outcomes. In particular, the results (...) showed female children to be more utilitarian than female adults in resolving classical moral dilemmas: they preferred an action that achieved a good outcome for a greater number of people. Within the mental model theory’s framework there is no reason to expect that females and males differ in their ability to reason, but at the moment the results for females cannot be generalized to males who were not properly represented in the adults groups of the two experiments. The result revealing that (female) children are more utilitarian than (female) adults, which is hard to explain via many current theories, was predicted by the mental model theory. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Playing Attention":Contemporary Aesthetics and Performing Arts Audience EducationMonica Prendergast (bio)IntroductionThe spectator is an essential element of the kind of play we call aesthetic.1We all watch television. We all go to the movies. Some of us also attend live performances such as plays, concerts, operas, dance recitals, poetry or prose readings, and so on. What are the differences to be found among these experiences? The audience experience of television or (...) film is a shared one, although a more fragmented sharing in the case of television, as it is with live arts events. We are aware that we are not alone in viewing a show, that it is a collective event. But we also realize that our presence does not really matter (aside from boosting ratings or adding to box office profits) and that the performance will continue with or without us. We may exit or enter the room or auditorium at will and never offend the actors, because their presence is "mediatized" and we are not sharing the same time or space with them.2 Attending a live performance is otherwise; our presence is a key element of the event and definitely can and does make a significant difference both for ourselves and for the performers. Although the size and qualities of the event and audience may alter this assertion — a huge stadium rock concert is arguably a more mediatized live performance than a small folk club date — it still holds true that presence is one of the most important qualities of audience in live performance.If we can accept that audience presence is central to performance, then it follows that aesthetic education in the performing arts needs to pay some attention to this phenomenon. In a First World culture that is currently over-saturated with mediatized performance, the future health and vitality of live performance is endangered if educators neglect to address the challenges and processes involved in being an audience for the performing arts in arts education curricula. This essay explores how aesthetic/arts education may [End Page 36] assist young people to grow in awareness and understanding of the essential role that is played by audience in attending performance. In examining the work of four contemporary aesthetic philosophers — Hans-Georg Gadamer, Paul Ricoeur, Paul Thom, and James O. Young — I focus on the areas of spectatorship, attention, interpretation, and evaluation/criticism as important qualities of audience-in-performance. I will then offer a possible curriculum framework for audience education in the performing arts that is performative in form and nature; that is, creative, experiential, emergent, and open question-driven.Both classical and contemporary aesthetic philosophy tends to ignore the performing arts in general and audience-in-performance in particular.3 Plato derides performance as anti-reason and Aristotle salvages it by focusing on the audience's experience of catharsis in tragedy, but this fascinating debate gets lost over time as philosophers get caught up in questions around the definition and nature of art. Examinations of audience in aesthetics tend to assume an audience engaged in the more reflective, contemplative, and individual activity of viewing a work of visual art, reading a poem, or appreciating beauty in general. Discussions of performing arts deal with the text of a play or the score of a musical piece as the primary aesthetic object, with performances of these texts or scores considered somehow secondary, less-definable therefore less worthy of serious philosophic consideration.4 Although a number of aesthetic philosophers have taken up performance and audience issues in more recent years, especially regarding issues around "authentic" performance of music on original instruments, the experience of audience-in-performance remains understudied.5 Others, such as Nick Zangwill, try to negate the audience altogether as being a relatively insignificant part of an aesthetic event and argue that the central focus of aesthetics should be on the artist and the creation of artworks.6Fortunately, there have been a few voices in the field that do attend more closely to performing arts in general and audience in particular, or whose work can be effectively applied to this distinct type of aesthetic event. In the next section I will describe... (shrink)

The present study explores the idea that human linguistic communication co-opted a pre-existing population-wide behavioural system that was shared among social group members and whose structure reflected the structure of the environment. This system is hypothesized to have emerged from interactions among individuals who had evolved the capacity to imitate arbitrary, functionless behaviour. A series of agent-based computer simulations test the separate and joint effects of imitation, pattern completion behaviour, environment structure and level of social interaction on such a population-wide (...) behavioural system. The results support the view that a system that could be co-opted for linguistic communication might arise in a population of agents equipped with arbitrary imitation for the purposes of pattern completion interacting in certain kinds of structured environments. Such pre-linguistic behavioural system could have bootstrapped communication and paved the way for biological capacities widely believed to be necessary for communication, such as shared intentionality and symbolicity, to evolve.

The results in this paper are in a context of abstract elementary classes identified by Shelah and Villaveces in which the amalgamation property is not assumed. The long-term goal is to solve Shelah’s Categoricity Conjecture in this context. Here we tackle a problem of Shelah and Villaveces by proving that in their context, the uniqueness of limit models follows from categoricity under the assumption that the subclass of amalgamation bases is closed under unions of bounded, -increasing chains.

We investigate the emergence of iconicity, specifically a bouba-kiki effect in miniature artificial languages under different functional constraints: when the languages are reproduced and when they are used communicatively. We ran transmission chains of participant dyads who played an interactive communicative game and individual participants who played a matched learning game. An analysis of the languages over six generations in an iterated learning experiment revealed that in the Communication condition, but not in the Reproduction condition, words for spiky shapes tend (...) to be rated by naive judges as more spiky than the words for round shapes. This suggests that iconicity may not only be the outcome of innovations introduced by individuals, but, crucially, the result of interlocutor negotiation of new communicative conventions. We interpret our results as an illustration of cultural evolution by random mutation and selection. (shrink)

This research note identifies for the first time the principium on book I of the Sentences by the prolific polymath Henry of Langenstein. This discovery, when combined with the four principia of the Augustinian Denis of Modena, provides the evidence necessary to demonstrate that Langenstein lectured on the Sentences at Paris in 1371-1372. The note also establishes the identity of the other eight bachelors of theology who participated in the principial debates that year.

In seeking the truth, philosophers have long used fiction and counterfactual scenarios to raise and answer questions, to foster dialogue or give a commentary on some facet of life. In this paper I will present a few well-known thought experiments from contemporary Western philosophers and highlight some characteristic traits of such thought experiments. I will then discuss some of the fictitious anecdotes that appear in the Zhuangzi. In comparing the features of Western thought experiments to fables from Zhuangzi, we will (...) see that although Zhuangzi’s stories would likely fail to be considered good philosophical thought experiments (according to the Western tradition), the very thing that makes them fail is arguably what allows the writings of Zhuangzi to continue to inspire philosophical reflection and dialogue.

Aristotle’s way of conceiving the relationship between mathematics and other branches of scientific knowledge is completely different from the way a contemporary scientist conceives it. This is one of the causes of the fact that we look at the mathematical passage we find in Aristotle’s works with the wrong expectation. We expect to find more or less stringent proofs, while for the most part Aristotle employs mere analogies. Indeed, this is the primary function of mathematics when employed in a philosophical (...) context: not a demonstrative tool, but a purely analogical model. In the case of the geometrical examples discussed in this paper, the diagrams are not conceived as part of a formalized proof, but as a work in progress. Aristotle is not interested in the final diagram but in the construction viewed in its process of development; namely in the figure a geometer draws, and gradually modifies, when he tries to solve a problem. The way in which the geometer makes use of the elements of his diagram, and the relation between these elements and his inner state of knowledge is the real feature which interests Aristotle. His goal is to use analogy in order to give the reader an idea of the states of mind involved in a more general process of knowing. (shrink)
