The relationship of organizational culture and leadership in the context of SBE organizations

Research questions: Main and first research question is to get a deeper insight into the relationship between the organizational culture (represented by the 4 main culture characteristics hierarchy, market, clan, and adhocracy), the leadership culture and "the outcome" of both towards the main organizational goal of all companies, to reach a real sustainable capability in organizational learning. Methods: Four empirical studies across different organizations using Quinn's Organizational Culture Assessment Inventory OCAI (Cameron & Quinn, 2011) to measure Organizational Culture and, independent from the leadership skills and traits itself, the "outcome" of the applied leadership culture using the "Leadership Productivity Model" LPM (Desjardins, 2012). Results: Although no direct linear correlation could be substantiated between the OCAI organizational culture profiles and the LPS leadership dimensions according to the leadership productivity model in the first step, yet the main elements of the suggested measurements (LPS, OCAI) create genuine value added in assessing and understanding an organization as an integral whole

Blazes: Coordination Analysis for Distributed Programs

Distributed consistency is perhaps the most discussed topic in distributed systems today. Coordination protocols can ensure consistency, but in practice they cause undesirable performance unless used judiciously. Scalable distributed architectures avoid coordination whenever possible, but under-coordinated systems can exhibit behavioral anomalies under fault, which are often extremely difficult to debug. This raises significant challenges for distributed system architects and developers. In this paper we present Blazes, a cross-platform program analysis framework that (a) identifies program locations that require coordination to ensure consistent executions, and (b) automatically synthesizes application-specific coordination code that can significantly outperform general-purpose techniques. We present two case studies, one using annotated programs in the Twitter Storm system, and another using the Bloom declarative language.Comment: Updated to include additional materials from the original technical report: derivation rules, output stream label

Ostracism and the Provision of a Public Good, Experimental Evidence

We analyze the effects of ostracism on cooperation in a linear public good experiment. Our results show that introducing ostracism increases contributions. Despite reductions in group size due to ostracism, the net effect on earnings is positive and significant.Experiment, Public Good, Ostracism

Isotropic-nematic phase equilibria of polydisperse hard rods: The effect of fat tails in the length distribution

We study the phase behaviour of hard rods with length polydispersity, treated within a simplified version of the Onsager model. We give a detailed description of the unusual phase behaviour of the system when the rod length distribution has a "fat" (e.g. log-normal) tail up to some finite cutoff. The relatively large number of long rods in the system strongly influences the phase behaviour: the isotropic cloud curve, which defines the where a nematic phase first occurs as density is increased, exhibits a kink; at this point the properties of the coexisting nematic shadow phase change discontinuously. A narrow three-phase isotropic-nematic-nematic coexistence region exists near the kink in the cloud curve, even though the length distribution is unimodal. A theoretical derivation of the isotropic cloud curve and nematic shadow curve, in the limit of large cutoff, is also given. The two curves are shown to collapse onto each other in the limit. The coexisting isotropic and nematic phases are essentially identical, the only difference being that the nematic contains a larger number of the longest rods; the longer rods are also the only ones that show any significant nematic ordering. Numerical results for finite but large cutoff support the theoretical predictions for the asymptotic scaling of all quantities with the cutoff length.Comment: 21 pages, 13 figure
