An increasing number of research teams are investigating the efficacy of brain-computer interface (BCI)-mediated interventions for promoting motor recovery following stroke. A growing body of evidence suggests that of the various BCI designs, most effective are those that deliver functional electrical stimulation (FES) of upper extremity (UE) muscles contingent on movement intent. More specifically, BCI-FES interventions utilize algorithms that isolate motor signals—user-generated intent-to-move neural activity recorded from cerebral cortical motor areas—to drive electrical stimulation of individual muscles or muscle synergies. BCI-FES (...) interventions aim to recover sensorimotor function of an impaired extremity by facilitating and/or inducing long-term motor learning-related neuroplastic changes in appropriate control circuitry. We developed a non-invasive, electroencephalogram (EEG)-based BCI-FES system that delivers closed-loop neural activity-triggered electrical stimulation of targeted distal muscles while providing the user with multimodal sensory feedback. This BCI-FES system consists of three components: (1) EEG acquisition and signal processing to extract real-time volitional and task-dependent neural command signals from cerebral cortical motor areas, (2) FES of muscles of the impaired hand contingent on the motor cortical neural command signals, and (3) multimodal sensory feedback associated with performance of the behavioral task, including visual information, linked activation of somatosensory afferents through intact sensorimotor circuits, and electro-tactile stimulation of the tongue. In this report, we describe device parameters and intervention protocols of our BCI-FES system which, combined with standard physical rehabilitation approaches, has proven efficacious in treating UE motor impairment in stroke survivors, regardless of level of impairment and chronicity.

This article is a discussion of the intersection between curriculum theory and agential realism as it emerged in the development of a curriculum theory course. During the process of designing such a course, I found myself wrestling with the different theoretical understandings of curriculum. What I came to realize was that while all of the theories I encountered have merits, none individually seem to capture the whole of what researchers/teachers understand to be curriculum as they encounter it in the classroom. (...) Also, the different theories seem to be incommensurable with each other and, thus, cannot be synthesized into a single more comprehensive theory. In response to these realizations and in an effort to develop the course, I turn to Karen Barad’s agential realism and specifically her theory of the apparatus. My conclusion is that curriculum theory itself is an apparatus. This article is an explanation of both that process of realization and the applicable theories of Barad’s agential realism. I conclude this article by arguing that engaging curriculum theory as a Baradian apparatus in courses for new researchers/teachers can prepare them to engage with those theories differently and with more agility in their future practice.

The recent shift in social science research toward philosophies of the more-than-human has pushed many scholars to question their understanding of units of analysis and agency. While many engage with agencies of the material, few have attempted to address what might be called the agency of ideas. Here, Alexander Pratt argues that engaging with the agency of ideas is particularly important when dealing with issues like racism, which is the focus of this article. He believes that one reason for (...) the lack of such engagement is the seemingly undefined nature of what we might think of as ideas. In this article, Pratt offers a conception of agential ideas developed through his reading of the metaphysics of Charles S. Peirce and those who have utilized Peirce's theories. This conception will provide an entry point for posthuman researchers to incorporate the protean nature of ideas into their own research methodologies. (shrink)

Early German Romanticism sought to respond to a comprehensive sense of spiritual crisis that characterised the late eighteenth century. The study demonstrates how the Romantics sought to bring together the new post-Kantian idealist philosophy with the inheritance of the realist Platonic-Christian tradition. With idealism they continued to champion the individual, while from Platonism they took the notion that all reality, including the self, participated in absolute being. This insight was expressed, not in the language of theology or philosophy, but through (...) aesthetics, which recognised the potentiality of all creation, including artistic creation, to disclose the divine. In explicating the religious vision of Romanticism, this study offers a new historical appreciation of the movement, and furthermore demonstrates its importance for our understanding of religion today.

In this article, the authors explore the impact of a potential future regulatory decision by FDA whether or not to continue its enforcement discretion policy allowing physicians to perform, and stool banks to sell, stool product for fecal microbiota transplantation as a treatment for recurrent Clostridium Difficile infection without an Investigative New Drug application. The paper looks at the Agency's regulatory options in light of the current gut microbiota based products that are in the FDA pipeline for drug approval and (...) the potential impact and repercussions of their approval on FDA action. In laying out FDA's options we consider the implications of market exclusivity and off-label use of newly approved drugs. Ultimately, we explore the potential impact of FDA's decision on patients, research, and innovation. (shrink)

Platonism has played a central role in Christianity and is essential to a deep understanding of the Christian theological tradition. At times, Platonism has constituted an essential philosophical and theological resource, furnishing Christianity with an intellectual framework that has played a key role in its early development, and in subsequent periods of renewal. Alternatively, it has been considered a compromising influence, conflicting with the faith's revelatory foundations and distorting its inherent message. In both cases the fundamental importance of Platonism, as (...) a force which Christianity defined itself by and against, is clear. Written by an international team of scholars, this landmark volume examines the history of Christian Platonism from antiquity to the present day, covers key concepts, and engages issues such as the environment, natural science and materialism.

Achieving space situational awareness requires, at a minimum, the identification, characterization, and tracking of space objects. Leveraging the resultant space object data for purposes such as hostile threat assessment, object identification, and conjunction assessment presents major challenges. This is in part because in characterizing space objects we reference a variety of identifiers, components, subsystems, capabilities, vulnerabilities, origins, missions, orbital elements, patterns of life, operational processes, operational statuses, and so forth, which tend to be defined in highly heterogeneous and sometimes inconsistent (...) ways. The Space Domain Ontologies are designed to provide a consensus-based realist framework for formulating such characterizations in a way that is both consistent and computable. Space object data are aligned with classes and relations in a suite of ontologies built around the existing Space Object Ontology. They are stored in a dynamically updated Resource Description Framework triple store, which can be queried to support space situational awareness and the needs of spacecraft operators and analysts. This paper provides an overview of the Space Domain Ontologies and their development and use. It presents the motivation for and advantages of the Space Domain Ontologies, including the benefits they provide for enhancing and maintaining long-term space situational awareness. (shrink)

Irenaeus, Coleridge and Gadamer all wrote about religion in distinct historical periods, however the work that each produced reflects the anthropological condition of the middle position. Furthermore, each thinker provides an opportunity for self-reflection about the motivations of faith without requiring the individual to abandon their religious belief in order to do so. In this manner they present a productive alternative to the required external views of the social sciences. The individual's position in mid-creation, his moral freedom and his historical (...) contingence all require the acceptance, commitment and trust of faith. Gnosticism, Empiricist thought and the desire to overcome historical contingency all reveal intellectual impatience in riposte to this condition. This intellectual impatience seeks the absolute without the need for faith. For Irenaeus, Coleridge and Gadamer such absolute, logocentric, complete systems end up alienating man from the reality of the incomplete condition that permeates his existence and the faith-requiring mythos that ultimate realities necessitate in order to be communicated.

The clinical clerkships in medical school are the first formal opportunity for trainees to apply bioethics concepts to clinical encounters. These clerkships are also typically trainees’ first sustained exposure to the “reality” of working in clinical teams and the full force of the challenges and ethical tensions of clinical care. We have developed a specialized, embedded ethics curriculum for Vanderbilt University medical students during their second year to address the unique experience of trainees’ first exposure to clinical care. Our embedded (...) curriculum is centered around core “ethics competencies” specific to the clerkship: for Medicine, advanced planning and end-of-life discussions; for Surgery, informed consent; for Pediatrics, the patient-family-provider triad; for Obstetrics and Gynecology, women’s autonomy, unborn child’s interests, and partner’s rights; and for Neurology/Psychiatry, decision-making capacity. In this paper, we present the rationale for these competencies, how we integrated them into the clerkships, and how we assessed these competencies. We also review the additional ethical issues that have been identified by rotating students in each clerkship and discuss our strategies for continued evolution of our ethics curriculum. (shrink)

We introduce a framework that can be used to model both mathematics and human reasoning about mathematics. This framework involves stochastic mathematical systems (SMSs), which are stochastic processes that generate pairs of questions and associated answers (with no explicit referents). We use the SMS framework to define normative conditions for mathematical reasoning, by defining a “calibration” relation between a pair of SMSs. The first SMS is the human reasoner, and the second is an “oracle” SMS that can be interpreted as (...) deciding whether the question–answer pairs of the reasoner SMS are valid. To ground thinking, we understand the answers to questions given by this oracle to be the answers that would be given by an SMS representing the entire mathematical community in the infinite long run of the process of asking and answering questions. We then introduce a slight extension of SMSs to allow us to model both the physical universe and human reasoning about the physical universe. We then define a slightly different calibration relation appropriate for the case of scientific reasoning. In this case the first SMS represents a human scientist predicting the outcome of future experiments, while the second SMS represents the physical universe in which the scientist is embedded, with the question–answer pairs of that SMS being specifications of the experiments that will occur and the outcome of those experiments, respectively. Next we derive conditions justifying two important patterns of inference in both mathematical and scientific reasoning: (i) the practice of increasing one’s degree of belief in a claim as one observes increasingly many lines of evidence for that claim, and (ii) abduction, the practice of inferring a claim’s probability of being correct from its explanatory power with respect to some other claim that is already taken to hold for independent reasons.

This article provides a survey of Walker Percy's criticism of what Pope Benedict XVI calls “scientificity,” which entails a constriction of the dynamic interaction of faith and reason. The process can result in the diminishment of ethical considerations raised by science's impact on public policy. Beginning in the 1950s, Percy begins speculating about the negative influence of scientificity. The threat of a political regime using weapons of mass destruction is only one of several menacing developments. The desacrilization of human life (...) from cradle to grave leads Percy to assert that modern science's impact is often radically incoherent. In The Moviegoer, Percy finds his existential and theistic voice that would enable him to advance his critique of science. (shrink)

Procrastination refers to voluntarily postponing an intended course of action despite expecting to be worse off for this delay, and students are considered to be especially negatively affected. According to estimates in the literature, at least half of the students believe procrastination impacts their academic achievements and well-being. As of yet, evidence-based ideas on how to differentiate severe from less severe cases of procrastination in this population do not exist, but are important in order to identify those students in need (...) of support. The current study recruited participants from different universities in Sweden to participate in an anonymous online survey investigating self-rated levels of procrastination, impulsivity, perfectionism, anxiety, depression, stress, and quality of life. Furthermore, diagnostic criteria for pathological delay as well as self-report items and open-ended questions were used to determine the severity of their procrastination and its associated physical and psychological issues. In total, 732 participants completed the survey. A median-split on the Pure Procrastination Scale and the responses to the PDC were used to differentiate two groups; “less severe procrastination”, and “severe procrastination”. For participants in the severe group, 96–97% considered procrastination to a problem, compared to 42–48% in the less severe group. The two groups also differed with regard to considering seeking help for procrastination, 35–38% compared to 5–7%. Participants in the severe group also reported more problems of procrastination in different life domains, greater symptoms of psychological issues, and lower quality of life. A thematic analysis of the responses on what physical issues were related to procrastination revealed that these were characterized by stress and anxiety, e.g., tension, pain, and sleep and rest, while the psychological issues were related to stress and anxiety, but also depression, e.g., self-criticism, remorse, and self-esteem. The current study recommends the PPS to be used as an initial screening tool, while the PDC can more accurately determine the severity level of procrastination for a specific individual. (shrink)

In this volume, critical scholars and educational activists explore the intricate dynamics between the enclosure of global commons and radical visions of a common social future that breaks through the logics of privatization, ecological degradation, and dehumanizing social hierarchies in education. In its institutional and informal configurations alike, education has been identified as perhaps the key stake in this struggle. Insisting on the urgency of an education that breaks free of the bonds of enclosure, the essays included in this volume (...) weave together bright threads of radical thought into a vivid tapestry illustrating a critical framework for enacting a global educational commons.
