    AbstractA topological space X is called a CO space, if every closed subset of X is homeomorphic to some clopen subset of X. Every ordinal with its order topology is a CO space. This work gives a complete classification of CO spaces which are continuous images of compact ordered spaces

    Fostering creativity across countries: The moderating effect of cultural bundles on creativity

    Research has traditionally focused on the moderating role of single cultural dimensions to capture differences in how individual creativity is fostered across cultures. Culture, however, is a multidimensional construct, with cultural dimensions operating interdependently. Building on this reasoning, we propose that the moderating effect of culture is better understood by focusing on the configuration of cultural bundles. We define a cultural bundle as set including the cultural value dimensions that characterize a given country, and the strength of the norms enforcing these values. We find support for this view in a mixed-methods study that combines a meta-analysis of 584 effect sizes from 205 studies set in 38 different countries with fuzzy-set qualitative comparative analysis (fs/QCA). We discuss the theoretical and practical implications of these findings, arguing for the importance of focusing on cultural bundles, rather than cultural dimensions in isolation, to understand the moderating effect of culture on creativity

    Skeletal Muscle Tissue Engineering System to Mimic In Vivo Development

    Skeletal muscle atrophy can occur for a number of reasons including degenerative diseases and age-related sarcopenia. Current pre-clinical studies for regeneration therapies are solely reliant on animal models, which do not accurately mimic human tissue and chemistry. The purpose of developing this device was to provide a reproducible manner of creating an in vitro skeletal muscle model that will aid in preclinical therapy testing. The device was designed to maintain a sterile environment for tissue culture, which provides anchorage, periodic strain, and generates an electric field to stimulate contraction. The intended output of the device is the controlled culture of a minimal functional unit of skeletal muscle that surpasses current standards of in vitro and in vivo pre-clinical models

    Essays in Education, Crime, and Job Displacement

    With a limited budget and resources, governments must decide how to allocate funds across a variety of factors which benefit society such as education, crime deterrence, and public safety. Each increase in spending on one area comes with the knowledge that this money cannot be spent on social problems in another area. As such, externalities and unexpected spillover effects impact the costs and benefits of public spending to society and may have large and meaningful implications on how to most effectively allocate resources across a multitude of outcomes. For example, an increase in education corresponds to an increase in the opportunity cost of engaging in criminal activity, decreasing the probability an individual commits crime. Likewise, loss of employment decreases the opportunity cost of engaging in criminal activity, increasing the probability an individual commits crime. Discrimination towards immigrants can impact their employment prospects which, in turn, impacts their decision to further pursue education. Identifying how these individual level factors have an impact on society is key to informing and designing effective public policy. This Ph.D. thesis, entitled “Essays in Education, Crime, and Job Displacement”, analyzes the determinants and social implications of these three factors. While independent, each essay within this thesis examines the impact of factors such as education, in terms of reduced crime, job loss, in terms of increased crime, and discrimination, in terms of its impact on the educational attainment of immigrants, on society

    A foundation for probabilistic beliefs with or without atoms

    We provide sufficient conditions for a qualitative probability (Bernstein, 1917; de Finetti, 1937; Koopman, 1940; Savage, 1954) that satisfies monotone continuity (Villegas, 1964; Arrow, 1970) to have a unique countably additive measure representation, generalizing Villegas (1964) to allow atoms. Unlike previous contributions, we do so without a cancellation or solvability axiom. First, we establish that when atoms contain singleton cores, unlikely cores—the requirement that the union of all cores is not more likely than its complement—is sufficient (Theorem 3). Second, we establish that strict third-order atom-swarming—the requirement that for each atom A, the less likely non-null events are (in an ordinal sense) more than three times as likely as A—is also sufficient (Theorem 5). This latter result applies to intertemporal preferences over streams of indivisible objects
