Review of Flesh and blood: adolescent gender diversity and violence, by Messerschmidt, J. W.
No full textEvidence that absorption in the π+ π− π− system in nuclear matter is stronger in the JP = 0− than in the JP = 1+ state
No full textIn the reaction π- + A → π+ π- π- + A at 15.1 GeV/c the coherently produced 3π mass spectrum has a broad peak around 1.1 GeV which consists mainly of a JP = 1+ state and of a smaller fraction of 0-. Comparing the observed dependence of the production of these diffractive states on the atomic weight A of the target nuclei with the optical model, we have studied the absorption of the produced states in nuclear matter. We have found the following values of the absorption cross-sections: σ2(0-) = 49-7+9 mb and σ2(1+) = 15.8-1.3+1.5 mb
Evidence for resonance behaviour of A1 and A3 mesons coherently produced on nuclei
No full textAn analysis of about 60 000 events produced in the reaction π-A → (π+π-π-)A on nine different nuclear targets A at 8.9, 12.9, and 15.1 GeV/c has been performed using the Illinois PWA program. In the A1 region our "coherent" sample of events (which contains about 11% of incoherently produced events) is described by only four partial waves: the 1+S and 1+P amplitudes, which both show a peak, and the O-S and O-P waves, which are rather constant. We observed variations of both 1+S and 1+P phases relative to the O-P phase by about 90° across the A1 peak. This observation suggests the presence of resonant 1+ waves in the A1 mass region (∼1.1 GeV). In the A3 region we observe that the 2- state shows resonance behaviour and that fπ and ρ{variant}π are two decays modes with amplitudes of opposite signs
A tentative model of Management Accounting and Control in the Integration Processes of Mergers & Acquisitions
No full textThis article combines the areas of mergers and acquisitions (M&As) and management accounting
and control systems (MACS) by developing a tentative model that shows the important variables and how they determine MACS’ involvement in M&A integration processes. M&As have grown, measured
both in numbers and size, in recent decades and have become very popular strategic business tactics to achieve economies of scale and scope. In fact, some believe that they have even exceeded the internal or ‘organic’ growth of organizations. However, approximately two of every three M&As fail to achieve the intended goals which were the stated reasons for the business deal. The explanation given for this high failure rate is often bad integration management, and this can also be assumed to be true when it comes to the integration of MACS. The aim with this article is to collect the content of the few explicit and the many implicit studies in the field and build a model that can be used for further research. Hence, this article is the result of a comprehensive literature study and it shows that the role and function of MACS in M&A integration processes can be interpreted in many different ways, above all depending on which perspective, view, or theory is used. From this follows, that the research area under investigation can be recognized in the context of three main dimensions. These are a socio-cultural one,
a political-ideological one, and a technical one. These fairly theoretical and research dependent
variables also have an impact on how more pragmatic variables are described. Five such main groups of more pragmatic variables are defined in this article and the MACS’ involvement in M&A integration processes is illustrated
Enhancement of strange and multi-strange hyperons and anti-hyperons in S-S and S-W interactions at 200 GeV/c
No full textStrange and multistrange hyperon production is expected to be enhanced in heavy ion interactions if a phase transition from hadronic matter to a quark-gluon plasma takes place. The production yields of Lambda s, s, Xi(-)s, and (+)s relative to the production of negative particles are presented for p-W, p-S, S-W, and S-S interactions at 200 GeV/c per nucleon and compared to those from p-Pb and Pb-Pb interactions at 158 GeV/c per nucleon. In particular, enhancements of strange and multistrange hyperons will be presented where hyperon yields are normalized to the yields of negative particles
