 Martin Glinz, Eine geführte Tour durch die Landschaft der Software-Prozesse und -Prozessverbesserung, Informatik/Informatique, Vol. 6 (6), 1999. (Journal Article)
In the last ten years, software processes and software process improvement have been recognized as fundamental constituents for the development and maintenance of quality software. Much effort has been devoted to the development of models and standards for software processes, process maturity determination and process improvement. This article gives an introduction to the concepts of software processes and process improvement and presents an overview of models and standards in this field. First, we introduce the principles of process-oriented software development and discuss both advantages and risks. Then we give an overview of software process models and standards. In a second part, we present the concept of process improvement and illustrate the basic improvement cycle. Finally, we survey models and standards for software process improvement. |

S Buehler, Regulatory reform of telecommunications in Switzerland, Telecommunications Policy, Vol. 22 (8), 1998. (Journal Article)
National policies towards the regulation of the telecommunications industry have undergone significant change in response to technological progress and increasing competition. This article discusses the consecutive revisions of the Swiss regulatory framework during the 1990's and presents lessons to be drawn from this process. After reviewing the Telecommunications Act (Fernmeldegesetz; FMG) 1992 and the reasons for its revision, this article presents the most important prescriptions of the FMG 98 concerning the licence regime, universal service, and interconnection. The implementation of the FMG 98 has led to a fundamental change in regulatory policy. However, transitional rules appear to promote excessively slow adjustments in the current industry configuration. |

Armin Schmutzler, Changing places—the role of heterogeneity and externalities in cumulative processes, International Journal of Industrial Organization, Vol. 16 (4), 1998. (Journal Article)
We consider a simple class of dynamic games. A continuum of players chooses between two actions (“locations”) in each period; per-period payoffs depend positively on the number of players choosing the same action. The resulting dynamics are investigated. If one location receives a favorable shock, the effects of the strength of externalities and the heterogeneity of the population on the extent of adjustment may be non-monotone and discontinuous, due to two competing effects. With stronger externalities (lower heterogeneity), less players move initially, but more players follow once the process has gained momentum. |

Liliana Winkelmann, Rainer Winkelmann, Tariffs, quotas and terms-of-trade: the case of New Zealand, Journal of International Economics, Vol. 46 (2), 1998. (Journal Article)
This paper reports quantitative information on the effects of tariffs and quotas on prices of individual goods. The analyses uses the natural experiment provided by a comprehensive unilateral trade policy reform in New Zealand to examine the response of foreign exporters to an incident of liberalisation that is unique in the developed world. The price effects of tariffs and quotas are estimated using a multidestination 7-digit longitudinal product-level dataset on export values and quantities. The effects are found to be by no means equivalent: whereas tariffs display no significant effect, the impact that quantitative restrictions have on the terms-of-trade of the country that imposes them are unequivocally detrimental and quantitatively important. |

Michel Habib, Alexander P Ljungqvist, Underpricing and IPO proceeds: a note, Economics Letters, Vol. 61 (3), 1998. (Journal Article)
An inverse relation between underpricing and IPO proceeds holds true because of dilution, even as uncertainty remains unchanged. The use of the inverse of IPO proceeds as a proxy for uncertainty may therefore be misleading. |

Klaus F Zimmermann, Rainer Winkelmann, Is job stability declining in Germany? Evidence from Count Data Models, Applied Economics, Vol. 30 (11), 1998. (Journal Article)
The macro evidence of increased adjustment pressure since the early 1970s suggests that job mobility should have increased. Hence, retrospective and spell data from the German Socio-Economic Panel are combined in order to test the hypothesis that job stability for German workers declined between 1974 and 1994. Using count data regression models in which we control for labour market experience, various demographic factors, and occupation, we find that job stability did not decrease, but if anything increased, between 1974 and 1994. Our finding suggests that labour market inflexibility is an important factor in explaining the European unemployment problem. |

Nous décrivons dans cet article un système d'extraction automatique de réponses. L'extraction automatique de réponses (EAR) a pour but de trouver les passages d'un document qui répondent directement à une question posée par un utilisateur. L'EAR est plus ambitieuse que la recherche d'informations et l'extraction d'informations dans le sens que les résultats de la recherche sont des phrases et non pas des documents en entier, et dans le sens que les questions peuvent être formulées de façon libre. Elle est par contre moins ambitieuse que les systèmes questions-réponses car les réponses ne sont pas générées à partir d'une base de connaissance, mais extraites des textes.
La version actuelle d'ExtrAns permet d'analyser la documentation en ligne (en Anglais) du système Unix (les ""man pages""), et construit une représentation sémantique (sous forme d'expressions logiques) des phrases. Un programme de démonstration de théorèmes trouve ensuite les passages pertinents qui sont mis en évidence dans leur contexte. |
