TL;DR: This paper presents a solution to support strategic processes in a PSEE by providing a flexible guidance during process enactment and shows that supporting processes is more concerned with the flexibility of guidance offered during the process performance than with enforcement of a collection of predefined process models.
Abstract: Process-centred Software Engineering Environments (PSEE) are the most recent generation of environments supporting software development activities. Most of PSEE are based on mechanisms promoting enforcement and automation of process activities. In this kind of mechanisms the process models are prescribed in a detailed and complete way. But the experience shows that supporting processes is more concerned with the flexibility of guidance offered during the process performance than with enforcement of a collection of predefined process models. In this paper, we present a solution to support strategic processes in a PSEE by providing a flexible guidance during process enactment.

Abstract: We report on the properties of theZ resonance from 62 500Z decays into fermion pairs collected with the ALEPH detector at LEP, the Large Electron-Positron storage ring at CERN. We findMZ=(91.193±0.016exp±0.030LEP) GeV, ΓZ=(2497±31) MeV, σhad0=(41.86±0.66)nb, and for the partial widths Γinv=(489±24) MeV, Γhad(1754±27) MeV, Γee=(85.0±1.6)MeV, Γμμ=(80.0±2.5) MeV, and Γττ=(81.3±2.5) MeV, all in good agreement with the Standard Model. Assuming lepton universality and using a lepton sample without distinction of the final state we measure Γu=(84.3±1.3) MeV. The forward-backward asymmetry in leptonic decays is used to determine the vector and axial-vector weak coupling constants of leptors,gv2(MZ2)=(0.12±0.12)×10−2 andgA2(MZ2)=0.2528±0.0040. The number of light neutrino species isNν=2.91±0.13; the electroweak mixing angle is sin2θW(MZ2)=0.2291±0.0040.
TL;DR: In this paper, upper and lower limits on excited neutrino couplings were derived from the total width of the Z width, independent of the v∗ decay modes, for the ALEPH detector at LEP.
TL;DR: In this paper, the branching ratios and partial widths for each channel were determined and found to be equal, consistent with lepton universality, and the number of light neutrino types, assuming only the standard model value for the ratio Θ e Θ v, was found to have 3.35 ± 0.41.

TL;DR: In this paper, an analysis of interdiscourse functions in argumentative activities in psychological consulting on radio is presented, where interdiscourses participate in persuasive premises by introducing sentences in relation to doxa and the topic, and the audience or the clients' actions.
Abstract: The present analysis is devoted to interdiscourse functions in argumentative activities in psychological consulting on radio. The interdiscourse participates in persuasive premises by introducing sentences in relation to doxa and the topic, and the audience or the clients'reactions. it also occurs in interpretative activities according to the psychological consulting's pattern and contributes to creating vulgates in relation to stabilized theories.
