    [Excerpt] The goal of this chapter, therefore, is to develop an integrative conceptual framework of active learning, and we do this by focusing on three primary issues. First, we define the active learning approach and contrast it to more traditional, passive instructional approaches. We argue that the active learning approach can be distinguished from not only more passive approaches to instruction but also other forms of experiential learning based on its use of formal training components to systematically influence trainees\u27 cognitive, motivational, and emotion self-regulatory processes. Second, we examine how specific training components can be used to influence each of these process domains. Through a review of prior research, we extract core training components that cut across different active learning interventions, map these components onto specific process domains, and consider the role of individual differences in shaping the effects of these components (aptitude-treatment interactions [ATIs]). A final issue examined in this chapter concerns the outcomes associated with the active learning approach. Despite its considerable versatility, the active learning approach is not the most efficient or effective means of responding to all training needs. Thus, we discuss the impact of the active learning approach on different types of learning outcomes in order to identify the situations under which it is likely to demonstrate the greatest utility. We conclude the chapter by highlighting research and practical implications of our integrated framework, and we outline an agenda for future research on active learning

    Active Learning: Effects of Core Training Design Elements on Self-Regulatory Processes, Learning, and Adaptability

    Get PDF
    This research describes a comprehensive examination of the cognitive, motivational, and emotional processes underlying active learning approaches, their effects on learning and transfer, and the core training design elements (exploration, training frame, emotion-control) and individual differences (cognitive ability, trait goal orientation, trait anxiety) that shape these processes. Participants (N = 350) were trained to operate a complex computer-based simulation. Exploratory learning and error-encouragement framing had a positive effect on adaptive transfer performance and interacted with cognitive ability and dispositional goal orientation to influence trainees’ metacognition and state goal orientation. Trainees who received the emotion-control strategy had lower levels of state anxiety. Implications for developing an integrated theory of active learning, learner-centered design, and research extensions are discussed

    Network model of immune responses reveals key effectors to single and co-infection dynamics by a respiratory bacterium and a gastrointestinal helminth

    Co-infections alter the host immune response but how the systemic and local processes at the site of infection interact is still unclear. The majority of studies on co-infections concentrate on one of the infecting species, an immune function or group of cells and often focus on the initial phase of the infection. Here, we used a combination of experiments and mathematical modelling to investigate the network of immune responses against single and co-infections with the respiratory bacterium Bordetella bronchiseptica and the gastrointestinal helminth Trichostrongylus retortaeformis. Our goal was to identify representative mediators and functions that could capture the essence of the host immune response as a whole, and to assess how their relative contribution dynamically changed over time and between single and co-infected individuals. Network-based discrete dynamic models of single infections were built using current knowledge of bacterial and helminth immunology; the two single infection models were combined into a co-infection model that was then verified by our empirical findings. Simulations showed that a T helper cell mediated antibody and neutrophil response led to phagocytosis and clearance of B. bronchiseptica from the lungs. This was consistent in single and co-infection with no significant delay induced by the helminth. In contrast, T. retortaeformis intensity decreased faster when co-infected with the bacterium. Simulations suggested that the robust recruitment of neutrophils in the co-infection, added to the activation of IgG and eosinophil driven reduction of larvae, which also played an important role in single infection, contributed to this fast clearance. Perturbation analysis of the models, through the knockout of individual nodes (immune cells), identified the cells critical to parasite persistence and clearance both in single and co-infections. Our integrated approach captured the within-host immuno-dynamics of bacteria-helminth infection and identified key components that can be crucial for explaining individual variability between single and co-infections in natural populations

    The New International Tax Diplomacy

    Get PDF
    International tax avoidance by multinational corporations is now frontpage news. At its core, the issue is simple: the tax regimes of different countries allow multinational corporations to book much of their income in low-tax or no-tax jurisdictions, and many of their expenses in high-tax jurisdictions, thereby significantly reducing their tax liabilities. In a time of public austerity, citizens and legislators around the world have been more focused on the resulting erosion of the corporate income tax base than ever before. In response, in 2012, the G-20—the gathering of the leaders of the world’s twenty largest economies—launched the Base Erosion and Profit Shifting (BEPS) project, the most extensive attempt to change international tax norms since the 1920s. In the course of the BEPS project, the field of international tax has adopted the institutional and procedural architecture for multilateral action used in international financial law. This Article is the first to ask whether that architecture will work in the international tax context. To answer that question, this Article first applies lessons from the international financial law literature to assess international tax agreements that are now being reached through soft-law instruments and procedures comparable to those that characterize international financial law. This initial analysis, which draws from the experience in international financial law, is largely pessimistic. However, this Article then describes how model tax treaty law—although also a form of soft law—is highly effective, and differentiates the political economy of international tax law from that of international financial law. As a result, a key theoretical point emerges: bifurcating analysis of multilateral efforts to change international tax norms into their Model Treaty-based and non-Model Treaty-based components is necessary in order to understand the new regime for international tax governance. At a more practical level, bifurcating the analysis highlights that observers should expect the Model Treaty-based parts of the BEPS project to be implemented, as well as most parts of the project focused on tax transparency. By contrast, sustained international coordination in implementing other dimensions of the project is doubtful. In reaching these conclusions, the Article contributes to the broader international economic governance literature by using a high-profile example from international tax diplomacy to show how underlying legal institutions affect the prospects for implementation of international regulatory agreements

    Electronic Payment Systems Development in a Developing Country: The Role of Institutional Arrangements

    Get PDF
    This paper examines the institutional arrangements in the development of Nigeria’s electronic payment system (EPS) using a new institutional economics (NIE) perspective. A case study of Nigeria’s EPS was carried out using semi structured interviews to collect data from 18 participating stakeholders; a thematic method was used for the data analysis. The study suggests that a well-functioning set of arrangements, which is lacking in the institutional setup in Nigeria may be required to build necessary institutional capacity suitable for development of safe and efficient electronic payment systems. Although the technological payment infrastructure in Nigeria is modern and of comparable standard, the failure to put in place reliable and relevant market and collaborative agreements has not enabled full exploitation of the available infrastructure. Current governance structures show elements of power struggle and distrust between stakeholders (players and regulators), hampering the creation of an environment that would sustain free market economic activities and effective development of payment systems

    Team Learning, Development, and Adaptation

    [Excerpt] Our purpose is to explore conceptually these themes centered on team learning, development, and adaptation. We note at the onset that this chapter is not a comprehensive review of the literature. Indeed, solid conceptual and empirical work on these themes are sparse relative to the vast amount of work on team effectiveness more generally, and therefore a thematic set of topics that are ripe for conceptual development and integration. We draw on an ongoing stream of theory development and research in these areas to integrate and sculpt a distinct perspective on team learning, development, and adaptation
