    “One More for Luck”: The Destruction of U971 by HMCS Haida and HMS Eskimo, 24 June 1944

    On the evening of 23 June 1944, HMCS Haida and HMS Eskimo set out from Plymouth, operational base of the 10th Destroyer Flotilla (10th DF), to conduct a sweep of the Western Approaches to the English Channel. Their role was to assist in securing these waters for the ongoing delivery of supplies and reinforcements to the Normandy bridgehead. Across the Channel to the southest, American, British and Canadian forces were now in their third week of fighting across the fields and hedgerows of Normandy. Operation OVERLORD had been the largest amphibious invasion in history and, dependent as it was on the unimpeded use of the sea, required an intensive concentration of air and naval forces to protect Allied supply convoys. This naval counterpart of OVERLORD was Operation NEPTUNE, and it was as part of this massive undertaken that Haida and Eskimo now steamed out of Plymouth

    Individualism-Collectivism and Group Creativity

    Get PDF
    Current research in organizational behavior suggests that organizations should adopt collectivistic values because they promote cooperation and productivity, while individualistic values should be avoided because they incite destructive conflict and opportunism. In this paper, we highlight one possible benefit of individualistic values that has not previously been considered. Because individualistic values can encourage uniqueness, such values might be useful when creativity is a desired outcome. Although we hypothesize that individualistic groups should be more creative than collectivistic groups, we also consider an important competing hypothesis: Given that collectivistic groups are more responsive to norms, they might be more creative than individualistic groups when given explicit instructions to be creative. The results did not support this competing hypothesis and instead show that individualistic groups instructed to be creative are more creative than collectivistic groups given the same instructions. These results suggest that individualistic values may be beneficial, especially when creativity is a salient goal

    The HR-Firm Performance Relationship: Can it be in the Mind of the Beholder?

    Get PDF
    This study examined whether respondents’ implicit theories of performance could impact their responses to surveys regarding HR practices and effectiveness. Senior Human Resource and Line Executives and MBA, graduate Engineering, and graduate HR students read scenarios of high and low performing firms and were asked to report on the prevalence of various HR practices and effectiveness of the HR function in each firm. Results indicated that all four groups of respondents held implicit theories that high performing firms were characterized by extensive HR practices and had highly effective HR functions relative to low performing firms. Subjects with substantial work experience reported greater differences between and high and low performing firms than did subjects with relatively little work experience. The implications of these results for research on the HR Practices – Firm Performance relationship are discussed

    Globalization, Urbanization and Nutritional Change in the Developing World

    Urbanization and globalization may enhance access to non traditional foods as a result of changing prices and production practices, as well as trade and marketing practices. These forces have influenced dietary patterns throughout the developing world. Longitudinal case study data from China indicate that consumption patterns closely reflect changes in availability, and that potentially obesogenic dietary patterns are emerging, with especially large changes in rural areas with high levels of urban infrastructure and resources. Recent data on women from 36 developing countries illustrate that these dietary shifts may have implications for overweight/obesity in urban and rural settings. These data emphasize the importance of developing country policies that include preventive measures to minimize further adverse shifts in diet and activity, and risk of continued rises in overweight.dietary patterns, developing countries, overweight, food policy, Agricultural and Food Policy, Community/Rural/Urban Development, Food Security and Poverty,

    The Effects of Research and Development Intensity on Managerial Compensation in Large Organizations

    Get PDF
    Agency theory, leading edge, and administrative life cycle perspectives all predict that organizations having high levels of Research and Development (R&D) intensity will follow different compensation strategies than organizations that are less R&D intensive. Using data from 110 organizations over a 5 year period, and controlling for organization differences in employee and job characteristics, we found support for this general prediction. Specifically, high R&D intensity organizations tended to have higher relative base pay, higher relative bonus pay, and greater relative eligibility for long-term incentive payments. We discuss the importance of further research into compensation decisions in R&D intensive firms, particularly the effects of such decisions on firms\u27 competitiveness

    Multiphoton resonances for all-optical quantum logic with multiple cavities

    Get PDF
    We develop a theory for the interaction of multilevel atoms with multimode cavities yielding cavity-enhanced multiphoton resonances. The locations of the resonances are predicted from the use of effective two- and three-level Hamiltonians. As an application we show that quantum gates can be realized when photonic qubits are encoded on the cavity modes in arrangements where ancilla atoms transit the cavity. The fidelity of operations is increased by conditional measurements on the atom and by the use of a selected, dual-rail, Hilbert space. A universal set of gates is proposed, including the Fredkin gate and iSWAP operation; the system seems promising for scalability

    Domain general learning: Infants use social and non-social cues when learning object statistics.

    Get PDF
    Previous research has shown that infants can learn from social cues. But is a social cue more effective at directing learning than a non-social cue? This study investigated whether 9-month-old infants (N = 55) could learn a visual statistical regularity in the presence of a distracting visual sequence when attention was directed by either a social cue (a person) or a non-social cue (a rectangle). The results show that both social and non-social cues can guide infants' attention to a visual shape sequence (and away from a distracting sequence). The social cue more effectively directed attention than the non-social cue during the familiarization phase, but the social cue did not result in significantly stronger learning than the non-social cue. The findings suggest that domain general attention mechanisms allow for the comparable learning seen in both conditions
