For the unbalanced one-way random effects model with heterogeneous error variances, we propose the non-informative priors for the between-group variance and develop the first- and second-order matching priors. It turns out that the second-order matching priors do not exist and the reference prior and Jeffreys prior do not satisfy a first-order matching criterion. We also show that the first-order matching prior meets the frequentist target coverage probabilities much better than the Jeffreys prior and reference prior through simulation study, and the Bayesian credible intervals based on the matching prior and reference prior give shorter intervals than the existing confidence intervals by examples. 相似文献

Functional principal component scores are commonly used to reduce mathematically infinitely dimensional functional data to finite dimensional vectors. In certain applications, most notably in finance, these scores exhibit tail behaviour consistent with the assumption of regular variation. Knowledge of the index of the regular variation, α, is needed to apply methods of extreme value theory. The most commonly used method of the estimation of α is the Hill estimator. We derive conditions under which the Hill estimator computed from the sample scores is consistent for the tail index of the unobservable population scores. 相似文献

In this paper we propose a new robust estimator in the context of two-stage estimation methods directed towards the correction of endogeneity problems in linear models. Our estimator is a combination of Huber estimators for each of the two stages, with scale corrections implemented using preliminary median absolute deviation estimators. In this way we obtain a two-stage estimation procedure that is an interesting compromise between concerns of simplicity of calculation, robustness and efficiency. This method compares well with other possible estimators such as two-stage least-squares (2SLS) and two-stage least-absolute-deviations (2SLAD), asymptotically and in finite samples. It is notably interesting to deal with contamination affecting more heavily the distribution tails than a few outliers and not losing as much efficiency as other popular estimators in that case, e.g. under normality. An additional originality resides in the fact that we deal with random regressors and asymmetric errors, which is not often the case in the literature on robust estimators. 相似文献

This article examines the heated debate over the National Educational Information System (NEIS) in South Korea. The NEIS has been introduced by the Ministry of Education. It collects information on every South Korean primary and secondary school in regional databases, including information regarding health records, religious backgrounds, military service, grades, attendance and other sensitive information relating to individual pupils and teachers. Using the cultural theory developed by Mary Douglas, Michael Thompson and Aaron Wildavsky, it is shown in which particular ways the rivals in this debate have been talking past, and misunderstood each other. On the basis of this cultural theory, a possible way out of this impasse is sketched. 相似文献

司法现代化在农村正遭遇着种种困境,这有其深刻的历史背景和现实基础。实现农村的司法现代化,一方面要对传统法律文化进行认真彻底的反思,肃清沿袭至今的消极影响;另一方面则应从制度上保障司法的公正性,在司法领域树立法律的权威。 相似文献

This paper is written for non-Asian family therapists who must deal with an increasing number of Asian-American client families. Unlike some writers in fthe field who advocate that client and therapist have the same ethnic background, the authors belive that cultural sensitivity can be learned. Several culturally important values are described, and suggestions on how to orient treatment to fit this client population are offered. A Detailed case example illustrates the treatment issues involued. 相似文献

Zusammenfassung Der Beitrag beschreibt Planung, Verlauf und abschlie?ende Beurteilung eines gruppendynamischen Seminars, in dem für angehende
Supervisorinnen und Supervisoren das Thema Organisations-Entwicklung dargestellt und vermittelt werden sollte. Ausgangspunkt
war die Kl?rung des Inhaltsraums von Organisations-Entwicklung als geplantem sozialen Wandel, der auf sozialwissenschaftlicher
Grundlage zielgerichtet, strategisch und mit Zeitperspektive in der Zusammenarbeit zwischen externer und interner Sach-, Prozess-
und Entscheidungskompetenz durchgeführt wird. Als Ziele des Seminars wurden festgelegt, Organisations-Entwicklung als sozialwissenschaftliches
Instrument zu begründen, Organisations-Entwicklung-Schritte zu konzipieren und sie kollegial zu kommunizieren. Darüber hinaus
wurden Qualit?tskriterien für das Seminar formuliert: Praxisn?he, Kl?rung des Inhaltsraum Selbstorganisation, Selbststeuerung,
Ressourcenaktivierung, Konfliktregulierung, Analyse des Gruppenprozesses, Nutzung von Feldkompetenz und Verhaltensmodellen,
Etablierung von Feedbackschleifen, Koordination und Synergie, kollegialer Austausch und Kl?rung pers?nlicher Organisations-Entwicklungs-Fragen.
Bausteine und Lernorte des Seminars waren das Plenum, die Lernpartnerschaft, das OE-Team, die Beobachterfunktion, die Tagesreflexion,
die Sitzung Frage und Antwort, die Darstellung von Praxisf?llen, das Plenum-Feinsteuerung, die Analyse der Arbeitsprozesse
des OE-Teams sowie Transfer und Auswertung. Der tats?chliche Verlauf des Seminars wird aus der Perspektive des Leiters kommentiert.
Anhand von Verlaufsbeobachtungen und Teilnehmer?u?erungen wird der Eindruck begründet, dass diese Form des Vorgehens als lernintensiv,
autonomief?rdernd und für die zu erwerbende Supervisionskompetenz als praxisrelevant betrachtet werden kann.

This article describes the plantification, progress and final evaluation of a group-dynamic seminar for future supervisors in which the topic organization development was presented and introduced. The content of organization development was first defined as a planned social change which is executed based on social sciences in a goal-oriented, strategic way which considers the time perspective of the cooperation between external and internal specialised-, process- and decision competence. Goals of the seminar were to justify that organisation development is a social science tool, to plan organization development steps and to communicate them to peer seminar participants. Further more, the following quality criteria for the seminar were formulated: practice orientation, definition of self-organisation content, self regulation, resources activation, conflict regulation, group process analysis, field competence and behaviour models usage, feedback establishment, coordination and synergy, mutual peer exchange and finding answers to personal questions about organization development. The building blocks and learn places of the seminar were the plenary sessions, the learning partnership, the od-teams, the observer function, the day analysis, the questions and answers session, the case study presentation, the analysis of the work processes as well as transfer and evaluation. The progression of the seminar is commented from the point of view of the seminar leader. Progress observations and participant’s feedback justify the impression that this way to conceptualise provides an intensive learning experience, supports autonomy and provides relevant and practical supervision competence.
