Forskningsöversikt (refereegranskat)abstract
- We report on the final electroweak measurements performed with data taken at the Z resonance by the experiments operating at the electron-positron colliders SLC and LEP. The data consist of 17 million Z decays accumulated by the ALEPH, DELPHI, L3 and OPAL experiments at LEP, and 600 thousand Z decays by the SLID experiment using a polarised beam at SLC. The measurements include cross-sections, forward-backward asymmetries and polarised asymmetries. The mass and width of the Z boson, m(Z) and Gamma(Z), and its couplings to fermions, for example the p parameter and the effective electroweak mixing angle for leptons, are precisely measured: m(Z) = 91.1875 +/- 0.0021 GeV, Gamma(Z) = 2.4952 +/- 0.0023 GeV, rho(l) = 1.0050 +/- 0.0010, sin(2)theta(eff)(lept) = 0.23153 +/- 0.00016. The number of light neutrino species is determined to be 2.9840 +/- 0.0082, in agreement with the three observed generations of fundamental fermions. The results are compared to the predictions of the Standard Model (SM). At the Z-pole, electroweak radiative corrections beyond the running of the QED and QCD coupling constants are observed with a significance of five standard deviations, and in agreement with the Standard Model. Of the many Z-pole measurements, the forward-backward asymmetry in b-quark production shows the largest difference with respect to its SM expectation, at the level of 2.8 standard deviations. Through radiative corrections evaluated in the framework of the Standard Model, the Z-pole data are also used to predict the mass of the top quark, m(t) = 173(+10)(+13) GeV, and the mass of the W boson, m(W) = 80.363 +/- 0.032 GeV. These indirect constraints are compared to the direct measurements, providing a stringent test of the SM. Using in addition the direct measurements of m(t) and m(W), the mass of the as yet unobserved SM Higgs boson is predicted with a relative uncertainty of about 50% and found to be less than 285 GeV at 95% confidence level.

Forskningsöversikt (refereegranskat)abstract
- Electroweak measurements performed with data taken at the electron positron collider LEP at CERN from 1995 to 2000 are reported. The combined data set considered in this report corresponds to a total luminosity of about 3 fb(-1) collected by the four LEP experiments ALEPH, DELPHI, 13 and OPAL, at centre-of-mass energies ranging from 130 GeV to 209 GeV. Combining the published results of the four LEP experiments, the measurements include total and differential cross-sections in photon-pair, fermion-pair and four-fermion production, the latter resulting from both double-resonant WW and ZZ production as well as singly resonant production. Total and differential cross-sections are measured precisely, providing a stringent test of the Standard Model at centre-of-mass energies never explored before in electron positron collisions. Final-state interaction effects in four-fermion production, such as those arising from colour reconnection and Bose Einstein correlations between the two W decay systems arising in WW production, are searched for and upper limits on the strength of possible effects are obtained. The data are used to determine fundamental properties of the W boson and the electroweak theory. Among others, the mass and width of the W boson, m(w) and Gamma(w), the branching fraction of W decays to hadrons, B(W -> had), and the trilinear gauge-boson self-couplings g(1)(Z), K-gamma and lambda(gamma), are determined to be: m(w) = 80.376 +/- 0.033 GeV Gamma(w) = 2.195 +/- 0.083 GeV B(W -> had) = 67.41 +/- 0.27% g(1)(Z) = 0.984(-0.020)(+0.018) K-gamma - 0.982 +/- 0.042 lambda(gamma) = 0.022 +/- 0.019.

An epistemology of globalizing firms

Tidskriftsartikel (refereegranskat)abstract
- This article discusses two concepts in an emerging theory of knowledge development in globalizing firms. The concept of "language games" is developed to shed light on the role of language in globalizing organizations. The concept of "self-similarity" enables discussions of changes in routines, processes, and structures as firms evolve from national to global organizations. © 1995.

Figuring out your competence configuration

Tidskriftsartikel (refereegranskat)abstract
- Johan Roos and Georg von Krogh go beyond contemporary theories of firms' competitive advantages to point out that most firms compete on competencies, and therefore possession of competence is the key to success. Competence itself is simply the synthesis of a firm's particular task and knowledge systems. The authors explore the nature of these systems and argue that skilfully combining them gives a firm its 'competence configuration' which represents the time potential of the organization. © 1992.

A perspective on knowledge, competence and strategy
- 1995

Ingår i: Personnel review. - : Emerald. - 0048-3486 .- 1758-6933. ; 24:3, s. 56-76
-
Tidskriftsartikel (refereegranskat)abstract
- Although the idea that competencies are underlying sustainable competitive advantages is central, there has been no thorough investigation into the very nature of competencies in the strategic management literature. Theories on the sociology of knowledge are used to advance the resource-based perspective of the firm into a coherent perspective of competencies. The implications on sustainable competitive advantages are discussed, by focusing on the processes of imitation of competencies in different social contexts. It is proposed that the emergent competence-based perspective of the firm has several important implications for management research and theory building.

- Building on the work of Prahalad and Bettis (1986, 1995), the objective of this article is to generate dialogue for further understanding of the concept of dominant logic. Our focus is on the level of basic assumptions. First, we demonstrate the conceptual plasticity of 'dominant logic. ' Then, we retrofit two relatively unknown concepts - self-reference and scale-with the concept of dominant logic, with its 1995 meaning. Finally, we discuss three implications of our venture.

- The objective of this essay is to contribute to a new perspective of strategic management by developing a new theory of organizational knowledge. The article focuses on how managers can understand and guide knowledge development processes in organizations. Our epistemology broadens strategic management to also include the advancement activities of the organization. In addition to discussing development of organizational knowledge, the essay also emphasises fundamental consequences for research methodology.

Conversation management

Tidskriftsartikel (refereegranskat)abstract
- Companies communicate internally through their own phrases and concepts - their own language. The local meaning of that language is very difficult to transpose into another company's language and culture. Georg von Krogh and Johan Roos point out that many businesses are careless in their use of language and internal conversations - yet nothing is of more importance to the company's strategy. These authors urge managers to develop their own internal company lexicon of language since language and knowledge development are interdependent. Most companies have mastery of operational conversations, but not of strategic conversations. This article sets out guidelines for managing and developing strategic conversations which are directed towards the future of the company. © 1995.

- In order to investigate the efficacy of treatment modalities favoured by us against flat acetowhite penile human papillomavirus HPV induced lesions, we studied retrospectively standardized medical records of 81 men who had been treated for this condition. The patients were treated surgically with diathermy n =32 or with a combination of both chemical topical application of podophyllotoxin and surgical treatment n =49 . The mean number of clinic visits was 9.1 range 1-19 , during a follow up time of mean 30.9 range 1-104 months for 78 of the men, 3 of them only visited the clinic once. The mean time for cure was 19.9 range 0-103 months. Only 12 15 patients were healed after one single treatment session, while as many as 50 62 required > 4 sessions. The mean number of surgical treatment sessions required for cure differed significantly P =0.0006 between the previously treated patients who needed a mean of 5.6 treatment sessions, compared to the previously untreated men who required surgery a mean of 3.4 times for cure.
