Monotonicity and Continuity of the Critical Capital Stock in the Dechert-Nishimura Model
No full textWe show that the critical capital stock of the Dechert-Nishimura (1983) model is a decreasing and continuous function of the discount factor. We also show that the critical capital stock merges with a nonzero steady state as the discount factor decreases to a certain boundary value, and that the critical capital stock converges to the minimum sustainable capital stock as the discount factor increases to another boundary value.Dechert-Nishimura model, Nonconvexity, Optimal growth, critical capital stock
A FUNCTORIAL APPROACH TO THE INFINITESIMAL THEORY OF GROUPOID
No full textLie algebroids are by no means natural as an infinitesimal counterpart of groupoids.
In this paper we propose a functorial construction called Nishimura algebroids for an
infinitesimal counterpart of groupoids. Nishimura algebroids intended for differential
geometry are of the same vein as Lawvere’s functorial notion of algebraic theory and
Ehresmann’s functorial notion of theory called sketches. We study totally intransitive
Nishimura algebroids in detail. Finally we show that Nishimura algebroids naturally
give rise to Lie algebroids.boo

Interpretationes Iuris Antiqui ::Dankesgabe für Shigeo Nishimura /
No full textDie Exegese ist die Königin der Wissenschaftsmethoden. Sie vereint in sich Erkenntnis, Erklärung und Anwendung in einer immer tiefer greifenden Konzentrierung, die am Ende zum Verständnis führt. Traditionell wird sie verbunden mit dem Lesen von juristischen und theologischen Texten und hat hierin eine lange Tradition.0Ein Großmeister der juristischen Exegese ist Shigeo Nishimura. Er hat unzählige römischrechtliche Texte scharfsinnig bearbeitet und seine Ergebnisse anderen Wissenschaftlern, in Japan und Europa, zugänglich gemacht. Zum Dank bieten ihm nun eine Reihe europäischer Wissenschaftler eine Sammlung von Exegesen dar, die schwierige Texte aus dem klassischen0römischen Recht behandeln. Auf diese Weise entstehen neue Einblicke in bekannte und weniger bekannte Stellen. Die Dankesgabe enthält Beiträge von F. Brandsma, A. Bürge, C.A. Cannata, T.J. Chiusi, Th. Finkenauer, É. Jakab, W. Kaiser, R. Knütel, S. Lohsse, U. Manthe, C. Masi Doria, M. Pennitz, P. Pichonnaz, J. Platschek, J.M. Rainer, G. Ries, M. Schermaier, G. Schiemann, B. Sirks, H.-D. Spengler, G. Thür, A. Wacke und L.

Equilibrium Cycles in a Two-Sector Economy with Sector Specific Externality
No full textIn this paper, we study the two-sector CES economy with sector-specific externality (feedback effects) following Nishimura and Venditti \(2004). We characterize the equilibrium paths in the case that allows negative externality. That equilibrium paths were not explicitly discussed by Nishimura and Venditti and show how the degree of externality may generate equilibrium cycles around the steady state.Two-sector economy, sector-specific externalities, indeterminacy, period-two cycles, capital-labor substitution
On the extremely low polarization in Comet C/2023 P1 (Nishimura)
No full textOn September 6 and 7 of 2023, we measured the degree of linear polarization of Comet C/2023 P1 (Nishimura) with the R filter. Our observations reveal an extremely low amplitude of positive polarization. Our modelling suggests Mg-rich silicate dust particles are the dominant species in the coma; whereas, an alternative explanation is that such low positive polarization in comets is attributed to the depolarizing effect of their gaseous emission. These two alternative explanations predict dramatically different polarimetric responses at small phase angle that can be discriminated in future polarimetric observations of Comet C/2023 P1 (Nishimura). © 2023 The Author(s).

Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Intramural pure pigment gallstones, a case report
No full textA case of intramural pure pigment gallstones, which were fortuitously found in post-mortem examination, is presented. The incidence, mechanism of formation of the stones and roentgenological diagnosis of the intramural gallstones, porcelain gall bladder, are mentioned.</p
"Closing the R&D Gap, Evaluating the Sources of R&D Spending"
No full textBoth spending and tax policies have been implemented in the United States with the goal of stimulating private sector research and development (R&D). Karier questions whether current R&D policy, especially the research and experimentation tax credit, can contribute to closing the gap between nondefense expenditures on R&D in the United States and such expenditures in other countries, such as Japan and Germany. He also explores possible changes to our current R&D policy to make it more effective.
