    Toward a Broader – But Still Rigorous – Definition of Leader Integrity: Commentary

    No full text
    [Excerpt] The impetus for this special issue of The Leadership Quarterly grew out of the desire of a small but enthusiastic group of leadership scholars who were interested in the concepts of integrity in general and behavioral integrity (the consistency between words and actions) in particular. Guest Editor Tony Simons\u27 (2002) theoretical article in Organization Science had sparked a great deal of interest in behavioral integrity, including the interest of a then-doctoral student at Binghamton University, Guest Editor Mike Palanski. Palanski was seeking advice for his dissertation, and Simons wished to build a cadre of scholars with an interest in leader behavioral integrity. A year or so later, Palanski had the “misfortune” of presenting a paper on integrity as the final presenter in the final session on the final day of the 2006 Academy of Management conference in Atlanta. To his surprise, the room was packed, and it quickly became clear that others also wished to study leader integrity in more depth

    On the L p-Poisson Semigroup Associated with Elliptic Systems

    No full text
    We study the infinitesimal generator of the Poisson semigroup in L associated with homogeneous, second-order, strongly elliptic systems with constant complex coefficients in the upper-half space, which is proved to be the Dirichlet-to-Normal mapping in this setting. Also, its domain is identified as the linear subspace of the L-based Sobolev space of order one on the boundary of the upper-half space consisting of functions for which the Regularity problem is solvable. Moreover, for a class of systems containing the Lamé system, as well as all second-order, scalar elliptic operators, with constant complex coefficients, the action of the infinitesimal generator is explicitly described in terms of singular integral operators whose kernels involve first-order derivatives of the canonical fundamental solution of the given system. Furthermore, arbitrary powers of the infinitesimal generator of the said Poisson semigroup are also described in terms of higher order Sobolev spaces and a higher order Regularity problem for the system in question. Finally, we indicate how our techniques may be adapted to treat the case of higher order systems in graph Lipschitz domains.The first author acknowledges financial support from the Spanish Ministry of Economy and Competitiveness, through the “Severo Ochoa Programme for Centres of Excellence in R&D” (SEV-2015-0554).

    Policing serious public disorder: the search for principles, policies and operational lessons. [In two volumes]

    No full text
    The paper examines the influence of central government on the police response to serious public disorder; the effectiveness or otherwise of the law and the way in which it is used by the police in their response to such disorder, and searches for sone principles which need to be followed if the police are to maintain the general support of the communities in which they are required to act. Some comparisons are made, and differences highlighted, between the police commander in his response to serious public disorder, once it has broken out, and the military commander in battle. But, guided by lessons from history, the paper principally concentrates on the environment in which the operational police commander is required to act in responding to actual or potential serious public disorder, pointing out that he is dependant for his success on firstly, an effective system of command and control; secondly, on an intelligence system which feeds relevant and accurate information on which he can make sound and informed decisions; and thirdly, the physical resources, e.g. personnel and equipment, and the approved tactics which enable him to restore public tranquility once disorder has broken out. But before he can use the physical resources effectively, he must have a sound strategy for dealing with actual or potential disorder

    Behavioral integrity as a critical ingredient for transformational leadership

    No full text
    Behavioral integrity is the perceived fit between espoused and enacted values. We propose that the maintenance of behavioral integrity is a highly problematic and consequential element of the successful management of change. Support for this view is drawn from the literatures on management fads, transformational leadership, trust and source credibility. Practical implications are developed.</jats:p

    Behavioral integrity: The perceived alignment between managers’ words and deeds as a research focus

    No full text
    and Deeds as a Research Focus This paper focuses on the perceived pattern of alignment between a manager&apos;s words and deeds, with special attention to promise keeping, and espoused and enacted values. It terms this perceived pattern of alignment “Behavioral Integrity. ” The literatures on trust, psychological contracts, and credibility combine to suggest important consequences for this perception, and literatures on hypocrisy, social accounts, social cognition, organizational change, and management fashions suggest key antecedents to it. The resulting conceptual model highlights an issue that is problematic in today&apos;s managerial environment, has important organizational outcomes, and is relatively unstudied

    Chemoenzymatic cascade processes for sustainable organic synthesis

    No full text
    Chemical production processes often require wasteful and expensive isolation as well as purification of intermediates. Catalytic cascades offer a unique opportunity to eliminate these inefficient and polluting steps, in particular when carefully orchestrated, involving enzymes and chemocatalysts. This thesis describes our efforts towards a genuinely sustainable chemo-enzymatic cascade for the synthesis of enantiopure amino acids, based on the benchmark Monsanto l-DOPA process. By replacing the wasteful chemical hydrolysis step of the l-DOPA process with an enzymatic reaction and by combining this with the sequential enantioselective catalytic reduction in one step a sustainable cascade process should be plausible.Applied Science

    Mechanisms of top-down facilitation in perception of visual objects studied by fMRI

    No full text
    Prior knowledge regarding the possible identity of an object facilitates its recognition from a degraded visual input, though the underlying mechanisms are unclear. Previous work implicated ventral visual cortex but did not disambiguate whether activity-changes in these regions are causal to or merely reflect an effect of facilitated recognition. We used functional magnetic resonance imaging to study top-down influences on processing of gradually revealed objects, by preceding each object with a name that was congruent or incongruent with the object. Congruently primed objects were recognized earlier than incongruently primed, and this was paralleled by shifts in activation profiles for ventral visual, parietal, and prefrontal cortices. Prior to recognition, defined on a trial-by-trial basis, activity in ventral visual cortex rose gradually but equivalently for congruently and incongruently primed objects. In contrast, prerecognition activity was greater with congruent priming in lateral parietal, retrosplenial, and lateral prefrontal cortices, whereas functional coupling between parietal and ventral visual (and also left lateral prefrontal and parietal) cortices was enhanced in the same context. Thus, when controlling for recognition point and stimulus information, activity in ventral visual cortex mirrors recognition success, independent of condition. Facilitation by top-down cues involves lateral parietal cortex interacting with ventral visual areas, potentially explaining why parietal lesions can lead to deficits in recognizing degraded objects even in the context of top-down knowledge

    Why managers should care about fairness: The effects of aggregate justice perceptions on organizational outcomes

    No full text
    This work examines the aggregation of justice perceptions to the departmental level and the business-unit level, the impact of these aggregate perceptions on business-unit-level outcomes, and the usefulness of the distinction between procedural and interpersonal justice at different levels of analysis. Latent variables analyses of individual-level and department-level data from 4,539 employees in 783 departments at 97 hotel properties showed that the 2 justice types exercise unique paths of impact on employees &apos; organizational commitment and thus on turnover intentions and discretionary service behavior. Business-unit-level analyses further demonstrate paths of association between aggregate justice perceptions, aggregate commitment levels, and the business-unit-level outcomes of employee turnover rates and customer satisfaction ratings
