    The right combination

    In the simplest sense, a composite is an object made up of two or more distinct parts. A common example is a composite image that may come from a series of photographs that together tell a bigger story than could be achieved with only one image. Within materials science, composite materials are put together from two or more components that remain distinct or separate within the final product. They can be as simple as a matrix material that envelops a reinforcing material, as when concrete surrounds steel bars that help prevent the concrete from failing under tension. Beyond this simple construct, composite forms now include layered structures and reinforcing agents that act in all three dimensions. The challenge is that the options for making a composite are almost limitless, but only a few combinations of materials will combine synergistically, and the design criteria may not be obvious. To design a material that will absorb more energy before breaking, a weaker reinforcing material may be added. When this composite fails, it may form a much larger number of cracks, and it is the additional crack length that makes the material tougher. ..

    Exploring the generative potential between positive organizational scholarship and management, spirituality, and religion research

    Though conceptually distinct, the fields ofpositive organizational scholarship (POS) and management, spirituality, and religion (MSR) consider various phenomena" in common. In this paper, we address a range oftopics that both disciplines explore, as well as topics that are exclusive to one domain but that may inform and enrich the other. We identify shared criticisms that both domains have faced and highlight different paths each field has taken toward establishing legitimacy. Our aim is to identify mutually relevant terrain where MSR research and POS can inform and enrich each other

    Interweaving positive and critical perspectives in management learning and teaching

    No full text
    Management learning is increasingly and rightfully called upon to address societal challenges beyond narrow concerns of economic performance. Within that agenda, we describe the generative aims of a special issue devoted to interweaving positive and critical perspectives in management learning and teaching. The five articles that comprise the issue describe the prospects for such interplay across a range of empirical and theoretical contexts. Together, these contributions suggest a way forward for work that is at once critical, positive, and reflexive. We identify key themes for future directions: the generative potential of contrarian learning dynamics, an ethics-first focus on ecological and human well-being, and the prospects of scholarly practice for systemic activism
