Zur Integration ehrenamticher Mitarbeiter/innen in Organisationen

The integration of volunteers in organizations On the background of the current changes in the general work conditions, a professional volunteer management in organizations is necessary. The author demonstrates, that in organizations a professional staff with management competences is a precondition. The peculiarities in leading volunteers are explained. The focus of the article are suggestions to a personnel development, in order to instruct and to attend individual employees or larger organizational units for a successful cooperation with volunteers. A special training as well as coaching and organizational development are delineated.     

Estimation of the variance of an adaptive estimator by bootstrapping

In this paper we propose a bootstrap-based method to estimate the standard error of adaptive estimators. We apply it in the standard problem of location estimation discussed in Randies and Hogg (1973) and in Hogg and Lenth (1984). Our adaptive estimator is based on a choice between the mean the 35% trimmed mean and the median. Finally, we carry out a simulation study to see how well the proposed method performs in small and moderate sample sizes.     

De copulis non est disputandum

Normal distribution of residuals is a traditional assumption in multivariate models. It is, however, not very often consistent with real data. Copulae allow for an extension of dependency models to nonellipticity and for separation of margins from the dependency. This paper provides a survey of copulae where different copula classes, estimation and simulation techniques and goodness-of-fit tests are considered. In the empirical section we apply different copulae to the static and dynamic Value-at-Risk of portfolio returns and Profit-and-Loss function.     

Monotony relations between distribution functions and their application to experimental design

In a linear regression model an estimator of the unknown coefficients is considered which, in special cases, includes the least squares estimator. In the ease of stable symmetric error distribution and by means of a certain monotony relation between distribution functions optimality of this estimator is proved and the designing problem is investigated. A robustness property of optimal designs against the designing criterion and some conclusions are given concerning the least squares estimator in the case of G- and C-optimality.

First German register based census in 2011

Summary The last censuses in Germany were accomplished in 1987 (former federal states) and 1981 (new federal states), respectively. Germany was the only country which did not participate in the EU-wide census in 2000. A traditional census was not feasible on political scale due to high costs and low acceptance by the population. Complete, precise and actual statistical registers as a condition for a register based census, are non-existent in Germany. Official statisticians developed a model for a register based census with interviewer-based surveys kept to a minimum. As the basic conditions were not favourable the model became very complex and many methods and procedures had to be developed for the special case of German registers. Core model elements were tested in a census test, such as quality of registers (e. g. municipal population registers, registers of the federal labour agency) and practicability of procedures (e. g. merging of registers, household generation). The test result was that a register based census is possible but much development work still has to be done, as the registers do not have an acceptable quality yet. Additional interviewer based surveys will be necessary for correction of errors of the register and survey of additional variables. This is also true if measures to improve municipal population registers, e. g. a feedback procedure and a nationwide tax number are taken into account. So these measures will not substitute the additional interviewer based surveys. Provided that the essential investments in development and preparation will be performed, Germany could participate in the 2011 EU-census-round with a register based census at a fraction of the cost of a traditional census. Finally, the census 2011 will show the real quality of the registers, how the model will work throughout the country and which measures have to be taken before the following census.

Zusammenfassung In Deutschland wurde die letzte Volksz?hlung 1987 (Alte Bundesl?nder) bzw. 1981 (Neue Bundesl?nder) durchgeführt. An dem EU-weiten Zensus um das Jahr 2000 beteiligte sich Deutschland als einziger EU-Staat nicht, da ein herk?mmlicher Zensus aus Kosten- und Akzeptanzgründen politisch nicht durchsetzbar war. Die Voraussetzungen für einen Registerzensus, d. h. Statistikregister, die alle ben?tigten Merkmale mit hinreichender Genauigkeit und Aktualit?t enthalten, waren und sind nicht vorhanden. Amtliche Statistiker entwickelten ein Modell für einen registergestützten Zensus mit einem m?glichst geringen Anteil an prim?rstatistischen Erhebungen. Aufgrund der für einen Zensus auf Basis von Registern ungünstigen Rahmenbedingungen wurde dieses Modell relativ komplex und in vielen Bereichen statistisches Neuland betreten. Wesentliche Elemente des Modells wurden in einem sog. Zensustest überprüft. Getestet wurden insbesondere die Qualit?t und Aktualit?t vorhandener Register, wie Melderegister und Dateien der Bundesagentur für Arbeit, sowie die Eignung und Wirksamkeit der Verfahren, wie Zusammenführungen der Daten aus verschiedenen Quellen und Haushaltegenerierung. Die Tests best?tigten die Machbarkeit des Zensusmodells, zeigten aber gleichzeitig, dass noch umfangreiche Entwicklungsarbeiten erforderlich sind und dass die Register noch keine Qualit?t aufweisen, die einen Verzicht auf prim?rstatistische Erhebungen zur Korrektur und Erg?nzung der Registerergebnisse zulassen. Dies gilt auch unter Berücksichtigung der in den n?chsten Jahren vorgesehenen Ma?nahmen zur Verbesserung der Qualit?t der Melderegister, wie die Einführung eines elektronischen Rückmeldeverfahrens oder die Erg?nzung der Melderegister um eine bundeseinheitliche Steuernummer für jede Person. Soweit in den n?chsten Jahren die erforderlichen Investitionen in Entwicklung und Vorbereitung eines registergestützten Zensus get?tigt werden, k?nnte in Deutschland im Rahmen der n?chsten EU-Zensusrunde ein solcher Zensus im Jahre 2011 zu einem Bruchteil der Kosten eines herk?mmlichen Zensus durchgeführt werden. Erst mit diesem Zensus k?nnte dann letztlich festgestellt werden, welche Qualit?t die Register zu diesem Zeitpunkt aufweisen, wie sich das Modell eines registergestützten Zensus (fl?chendeckend) in der Praxis bew?hrt und welche Ma?nahmen für darauf folgende Zensen in Angriff genommen werden müssen.
