Using cross-functional, cross-firm teams to co-create value: The role of financial measures

Increasingly, the involvement of representatives from all major business functions in cross-functional, crossfirmteams is being viewed as a means to develop and maintain profitable business-to-business relationships.However, if the measurements of the value co-created in these relationships with customers and suppliers donot incorporate the financial outcomes of joint cross-functional initiatives, managers can be led to makedecisions that jeopardize the long-term profitability of the two firms. In this paper, the authors explore thedifferences in value co-creation when a company is linked to key customers and key suppliers through crossfunctionalteams and when it is not. Using a case study approach, the authors measured value co-creation infinancial terms and describe how managers changed their behaviors toward customers and suppliers whenthey were able to compare the value that was being co-created in each relationship. In each pair ofrelationships, one involved cross-functional teams and the other did not. The results indicate that crossfunctional,cross-firm involvement leads to increased value co-creation. The research suggests that marketingscholars and managers should emphasize the use of cross-functional teams that involve all major functions tomanage relationships with key customers, and should incorporate financial measures in the evaluation ofrelationship performance

Aperture taper determination for the half-scale accurate antenna reflector

A simulation is described of a proposed microwave reflectance measurement in which the half scale reflector is used in a compact range type of application. The simulation is used to determine an acceptable aperture taper for the reflector which will allow for accurate measurements. Information on the taper is used in the design of a feed for the reflector

Measured performance of the half-scale accurate antenna reflector

A corrugated horn was designed and fabricated for use as a feed for the half-scale accurate antenna reflector. This feed allows the reflector to be used in a compact range configuration as part of a microwave reflectance measuring system. The horn design is described, and the measured farfield patterns of the horn are presented. The horn was installed at the focus of the reflector, and the nearfield of the antenna was measured. The results of these measurements are presented and discussed with respect to the compact range application

Emergent Time and the M5-Brane

We consider the maximal super-Yang-Mills theory in 5 Euclidean dimensions with SO(5) R-symmetry and 16 supersymmetries. We argue that the strong coupling limit of this theory (with a possible UV completion) has an emergent time dimension and gives a description of the 5+1 dimensional Lorentz invariant (2,0) theory of the M5-brane, compactified on a timelike circle with radius R=g^2/4\pi^2 . Our discussion involves issues of quantization of Euclidean theories without time.Comment: 1+40 page

Description and operation of a microwave reflectance measurement system

A recent effort at the NASA Lewis Research Center (LeRC), Microwave System Laboratory was to develop the capability to perform farfield reflectance measurements. This effort has resulted, to date, in a system that can perform X-band, monostatic, measurements of test objects. The system and the measurement procedure are described. Data are presented which assists in the evaluation of the quality of the measurements obtained with the system

Ring element dynamic stresses

The stresses in the CTRAPRG and CTRIARG ring elements are not calculated for any of the dynamic solutions in the current COSMIC version of NASTRAN. A DMAP alter sequence for Solution 8 and post-processing program, NASTPOST, are presented to calculate these stresses. Test cases are used which describe the method. The stiffness and the consistent versus concentrated mass problems ascribed to this element are reviewed. The DMAP alter sequence introduces Solution 8 displacements to a Solution 1 module to calculate real and imaginary stress components during the execution of Solution 8. The post-processor, NASTPOST, calculates the magnitude/phase stress results. The DMAP sequence was written specifically for level 52 MSC/NASTRAN, but can certainly be used for any COSMIC version with slight modification

Contractile properties of fibroblasts derived from primary frozen shoulder and effects of TGF beta 1 stimulation

INTRODUCTION: Primary Frozen Shoulder (PFS) is a debilitating disease of unknown aetiology. There is fibrosis and contracture of the coracohumeral ligament, tissues of the rotator interval and the glenohumeral ligaments, leading to restrictive shoulder movements requiring surgical intervention [1]. Frozen shoulder has been postulated to be dupuytren’s disease of the shoulder with an association inferred since 1936. The purpose of the study was to test the hypothesis that cellular mechanisms of fibroblasts derived from primary frozen shoulder exhibited similar activity in terms of contraction and response to cytokine (transforming growth factor beta1) to fibroblasts derived from dupuytren’s disease. Understanding of cellular responses is critical to developing non surgical treatment strategies

Negative 4-Probe Conductances of Mesoscopic Superconducting Wires

We analyze the longitudinal 4-probe conductance of mesoscopic normal and superconducting wires and predict that in the superconducting case, large negative values can arise for both the weakly disordered and localized regimes. This contrasts sharply with the behaviour of the longitudinal 4-probe conductance of normal wires, which in the localized limit is always exponentially small and positive.Comment: Latex, 3 figures available on request to [email protected] (Simon Robinson

Crossed conductance in FSF double junctions: role of out-of-equilibrium populations

We discuss a model of Ferromagnet / Superconductor / Ferromagnet (FSF) double junction in which the quasiparticles are not in equilibrium with the condensate in a region of the superconductor containing the two FS contacts. The role of geometry is discussed, as well as the role of a small residual density of states within the superconducting gap, that allows a sequential tunneling crossed current. With elastic quasiparticle transport and the geometry with lateral contacts, the crossed conductances in the sequential tunneling channel are almost equal in the normal and superconducting phases, if the distance between the FS interfaces is sufficiently small. The sequential tunneling and spatially separated processes (the so-called crossed Andreev reflection and elastic cotunneling processes) lead to different signs of the crossed current in the antiparallel alignment for tunnel interfaces.Comment: 8 pages, 4 figure
