Achieving space domain awareness requires the identification, characterization, and tracking of space objects. Storing and leveraging associated space object data for purposes such as hostile threat assessment, object identification, and collision prediction and avoidance present further challenges. Space objects are characterized according to a variety of parameters including their identifiers, design specifications, components, subsystems, capabilities, vulnerabilities, origins, missions, orbital elements, patterns of life, processes, operational statuses, and associated persons, organizations, or nations. The Space Object Ontology provides a consensus-based realist framework (...) for formulating such characterizations in a computable fashion. Space object data are aligned with classes and relations in the Space Object Ontology and stored in a dynamically updated Resource Description Framework triple store, which can be queried to support space domain awareness and the needs of spacecraft operators. This paper presents the core of the Space Object Ontology, discusses its advantages over other approaches to space object classification, and demonstrates its ability to combine diverse sets of data from multiple sources within an expandable framework. Finally, we show how the ontology provides benefits for enhancing and maintaining longterm space domain awareness. (shrink)

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)

We have begun work on two separate but related ontologies for the study of neurological diseases. The first, the Neurological Disease Ontology (ND), is intended to provide a set of controlled, logically connected classes to describe the range of neurological diseases and their associated signs and symptoms, assessments, diagnoses, and interventions that are encountered in the course of clinical practice. ND is built as an extension of the Ontology for General Medical Sciences — a high-level candidate OBO Foundry ontology that (...) provides a set of general classes that can be used to describe general aspects of medical science. ND is being built with classes utilizing both textual and axiomatized definitions that describe and formalize the relations between instances of other classes within the ontology itself as well as to external ontologies such as the Gene Ontology, Cell Ontology, Protein Ontology, and Chemical Entities of Biological Interest. In addition, references to similar or associated terms in external ontologies, vocabularies and terminologies are included when possible. Initial work on ND is focused on the areas of Alzheimer’s and other diseases associated with dementia, multiple sclerosis, and stroke and cerebrovascular disease. Extensions to additional groups of neurological diseases are planned. The second ontology, the Neuro-Psychological Testing Ontology (NPT), is intended to provide a set of classes for the annotation of neuropsychological testing data. The intention of this ontology is to allow for the integration of results from a variety of neuropsychological tests that assay similar measures of cognitive functioning. Neuro-psychological testing is an important component in developing the clinical picture used in the diagnosis of patients with a range of neurological diseases, such as Alzheimer’s disease and multiple sclerosis, and following stroke or traumatic brain injury. NPT is being developed as an extension to the Ontology for Biomedical Investigations. (shrink)

ObjectiveCo-morbid insomnia and sleep apnea is a common and debilitating condition that is more difficult to treat compared to insomnia or sleep apnea-alone. Emerging evidence suggests that cognitive behavioral therapy for insomnia is effective in patients with COMISA, however, those with more severe sleep apnea and evidence of greater objective sleep disturbance may be less responsive to CBTi. Polysomnographic sleep study data has been used to predict treatment response to CBTi in patients with insomnia-alone, but not in patients with COMISA. (...) We used randomized controlled trial data to investigate polysomnographic predictors of insomnia improvement following CBTi, versus control in participants with COMISA.MethodsOne hundred and forty five participants with insomnia and sleep apnea [apnea-hypopnea index ≥ 15] were randomized to CBTi or no-treatment control. Mixed models were used to investigate the effect of pre-treatment AHI, sleep duration, and other traditional, and novel [quantitative electroencephalography ] polysomnographic predictors of between-group changes in Insomnia Severity Index scores from pre-treatment to post-treatment.ResultsCompared to control, CBTi was associated with greater ISI improvement among participants with; higher AHI, less wake after sleep onset, and less N3 sleep. No quantitative electroencephalographic, or other traditional polysomnographic variables predicted between-group ISI change.DiscussionAmong participants with COMISA, higher OSA severity predicted a greater treatment-response to CBTi, versus control. People with COMISA should be treated with CBTi, which is effective even in the presence of severe OSA and objective sleep disturbance. (shrink)

We give a comparison inequality that allows one to estimate the tail probabilities of sums of independent Banach space valued random variables in terms of those of independent identically distributed random variables. More precisely, let X1, . . . , Xn be independent Banach-valued random variables. Let I be a random variable independent of X1, . . . , Xn and uniformly distributed over {1, . . . , n}. Put ˜.

In the paper, which pretends to be a program manifesto, its authors justify a necessity of the new theoretical approach to culture which they call a “strong program” in sociology of culture. While the existing sociological approaches to culture bear a reductionist character, the “strong program” treats culture in terms of its autonomy. After a general review of the sociological conceptions of culture authors analyze the most significant approaches within the “weak program.” In the core section of the paper they (...) discuss the required steps that will make a “strong program” possible on the grounds of synthesis of structuralism and hermeneutics.

This unique book brings together international scholars from around the globe to examine how different feminist theories are being used in early childhood research, policy and pedagogy. The array of feminist discourses captured by the authors offer contextualised possibilities for disrupting dominant patriarchal beliefs and producing change. The authors address and challenge how early childhood experiences, institutions and practices produce gendered effects across and within diverse contexts and demonstrate how feminism(s) in action can be used to reconceptualise research methods, government (...) policy, children's learning, teaching practice and educational resources. In this way, the book contributes to creating new knowledge connections and community alliances in the global effort to end gender-based inequalities across local and global communities. (shrink)

Phenomenology is the general study of the structure of experience, from thought and perception, to self-consciousness, bodily-awareness, and emotion. It is both a fundamental area of philosophy and a major methodological approach within the human sciences. Experiencing Phenomenology is an outstanding introduction to phenomenology. Approaching fundamental phenomenological questions from a critical, systematic perspective whilst paying careful attention to classic phenomenological texts, the book possesses a clarity and breadth that will be welcomed by students coming to the subject for the first (...) time. Accessibly written, each chapter relates classic phenomenological discussions to contemporary issues and debates in philosophy. The following key topics are introduced and explained: the methodological foundations of phenomenology intentionality as the ‘mark of the mental’ and the problem of non-existent objects perceptual experience, including our awareness of things, properties, and events the experience of body, self, and others imaginative and emotional experience detailed discussions of classical phenomenological texts, including: Brentano's _Psychology from an Empirical Standpoint _ Husserl's _Logical Investigations_, _Cartesian Meditations, _and On_ the Phenomenology of the Consciousness of Internal Time _ Heidegger’s _History of The Concept of Time,_ and _Being and Time _ Stein's _On the Problem of Empathy _ Sartre's _Transcendence of the Ego_, _Sketch for a Theory of the Emotions,_ and _The Imaginary _ Merleau-Ponty's Phenomenology of Perception. Also included is a glossary of key terms and suggestions for further reading, making this book an ideal starting point for anyone new to the study of phenomenology, not only in Philosophy but related disciplines such as Psychology and Sociology.

We are developing the Neurological Disease Ontology (ND) to provide a framework to enable representation of aspects of neurological diseases that are relevant to their treatment and study. ND is a representational tool that addresses the need for unambiguous annotation, storage, and retrieval of data associated with the treatment and study of neurological diseases. ND is being developed in compliance with the Open Biomedical Ontology Foundry principles and builds upon the paradigm established by the Ontology for General Medical Science (OGMS) (...) for the representation of entities in the domain of disease and medical practice. Initial applications of ND will include the annotation and analysis of large data sets and patient records for Alzheimer’s disease, multiple sclerosis, and stroke. (shrink)

Background: COVID-19 pandemic has led to heightened moral distress among healthcare providers. Despite evidence of gendered differences in experiences, there is limited feminist analysis of moral distress. Objectives: To identify types of moral distress among women healthcare providers during the COVID-19 pandemic; to explore how feminist political economy might be integrated into the study of moral distress. Research Design: This research draws on interviews and focus groups, the transcripts of which were analyzed using framework analysis. Research Participants and Context: 88 (...) healthcare providers, based in British Columbia Canada, participated virtually. Ethical Considerations: The study received ethical approval from Simon Fraser University. Findings: Healthcare providers experienced moral dilemmas related to ability to provide quality and compassionate care while maintaining COVID-19 protocols. Moral constraints were exacerbated by staffing shortages and lack of access to PPE. Moral conflicts emerged when women tried to engage decision-makers to improve care, and moral uncertainty resulted from lack of clear and consistent information. At home, women experienced moral constraints related to inability to support children’s education and wellbeing. Moral conflicts related to lack of flexible work environments and moral dilemmas developed between unpaid care responsibilities and COVID-19 risks. Women healthcare providers resisted moral residue and structural constraints by organizing for better working conditions, childcare, and access to PPE, engaging mental health support and drawing on professional pride. Discussion: COVID-19 has led to new and heightened experiences of moral distress among HCP in response to both paid and unpaid care work. While many of the experiences of moral distress at work were not explicitly gendered, implicit gender norms structured moral events. Women HCP had to take it upon themselves to organize, seek out resources, and resist moral residue. Conclusion: A feminist political economy lens illuminates how women healthcare providers faced and resisted a double layering of moral distress during the pandemic. (shrink)
