Organizational Development: An Assessment with Implications for Clinical Sociology

This paper examines organizational development (OD) as a clinical sociological strategy. OD techniques are diverse and include interventions ranging from stress management to quality-of-work-life programs. Strengths and weaknesses of OD approaches and reasons for the recent reemergence of interest in organizational and human resource development are explored. Four specific criticisms of OD are discussed: (1) lack of congruence in values, cognition, and action; (2) failure to examine meta-assumptions and values of organizational problem solving and learning; (3) simplistic understanding of organizational politics; (4) inability to create internal changes that deal with external complexity and environmental turbulence. Three issues are raised: (1) the proper unit of analysis for clinical sociological action research; (2) the incorporation of macro-level concepts like culture and systems in conceptualizing organizational development and change; (3) the identification and explanation of learning co straints under which organizations and individuals operate

Conformal Mapping on Rough Boundaries II: Applications to bi-harmonic problems

We use a conformal mapping method introduced in a companion paper to study the properties of bi-harmonic fields in the vicinity of rough boundaries. We focus our analysis on two different situations where such bi-harmonic problems are encountered: a Stokes flow near a rough wall and the stress distribution on the rough interface of a material in uni-axial tension. We perform a complete numerical solution of these two-dimensional problems for any univalued rough surfaces. We present results for sinusoidal and self-affine surface whose slope can locally reach 2.5. Beyond the numerical solution we present perturbative solutions of these problems. We show in particular that at first order in roughness amplitude, the surface stress of a material in uni-axial tension can be directly obtained from the Hilbert transform of the local slope. In case of self-affine surfaces, we show that the stress distribution presents, for large stresses, a power law tail whose exponent continuously depends on the roughness amplitude

Characterization of the first true coaxial 18-fold segmented n-type prototype detector for the GERDA project

The first true coaxial 18-fold segmented n-type HPGe prototype detector produced by Canberra-France for the GERDA neutrinoless double beta-decay project was tested both at Canberra-France and at the Max-Planck-Institut fuer Physik in Munich. The main characteristics of the detector are given and measurements concerning detector properties are described. A novel method to establish contacts between the crystal and a Kapton cable is presented.Comment: 21 pages, 16 Figures, to be submitted to NIM

The Photobiomodulation Effect of 940nm Laser Irradiation on Enterococcus faecalis in Human Root Dentin Slices of Varying Thicknesses

The main etiological factor of pulpal and periapical infections is the invasion of bacteria into the pulpal and endodontic systems.1 Successful treatment of these infections would require the removal and/or destruction of these microorganisms and create an effective coronal and apical seal to prohibit the reinfection of bacteria and influx of nutrients into the endodontic system. The ability of bacteria to penetrate deep into the dentin tubules and to form biofilms as well as the adhesion of certain bacteria to the dentin walls makes the destruction and removal of bacteria from the three-dimensional dentinal network a challenging task.2,3 Due to the complexity of this network, about 30%-45% of the root canal system escapes chemo-mechanical instrumentation4 as per the normal endodontic procedure with the dentist. Lasers have been used as an additional step to kill bacteria that could not be reached by chemo-mechanical instrumentation. Studies show that in favourable conditions, bacteria can penetrate to a depth of more than 1000 μm into the dentinal tubules.2 Numerous previous studies have been conducted to evaluate the bactericidal effect of various wavelengths of lasers, but most of these studies were conducted on dentine slices of 100, 300, 500, and 1000 μm.5-7 They were conducted with dentine samples up to 1000 μm, therefore limiting our understanding as to the effects of lasers and biocides, with one study beyond 2000 μm.8 This in vitro study aimed to compare the photobiomodulation effect of a 940 nm laser on Enterococcus faecalis through varying thicknesses of human root dentin slices

Conformal Mapping on Rough Boundaries I: Applications to harmonic problems

The aim of this study is to analyze the properties of harmonic fields in the vicinity of rough boundaries where either a constant potential or a zero flux is imposed, while a constant field is prescribed at an infinite distance from this boundary. We introduce a conformal mapping technique that is tailored to this problem in two dimensions. An efficient algorithm is introduced to compute the conformal map for arbitrarily chosen boundaries. Harmonic fields can then simply be read from the conformal map. We discuss applications to "equivalent" smooth interfaces. We study the correlations between the topography and the field at the surface. Finally we apply the conformal map to the computation of inhomogeneous harmonic fields such as the derivation of Green function for localized flux on the surface of a rough boundary
