Challenging the "inoffensiveness" of regular cannabis use by its associations with other current risky substance use--a census of 20-year-old Swiss men.

3,537 men enrolling in 2007 for mandatory army recruitment procedures were assessed for the co-occurrence of risky licit substance use among risky cannabis users. Risky cannabis use was defined as at least twice weekly; risky alcohol use as 6+ drinks more than once/monthly, or more than 20 drinks per week; and risky tobacco use as daily smoking. Ninety-five percent of all risky cannabis users reported other risky use. They began using cannabis earlier than did non-risky users, but age of onset was unrelated to other risky substance use. A pressing public health issue among cannabis users stems from risky licit substance use warranting preventive efforts within this age group.

WAIS seminar: Publication Workflows for Scientific Data

Wednesday 23rd April 2014 Speaker(s): Willi Hasselbring Organiser: Leslie Carr Time: 23/04/2014 11:00-11:50 Location: B32/3077 File size: 669 Mb Abstract For good scientific practice, it is important that research results may be properly checked by reviewers and possibly repeated and extended by other researchers. This is of particular interest for "digital science" i.e. for in-silico experiments. In this talk, I'll discuss some issues of how software systems and services may contribute to good scientific practice. Particularly, I'll present our PubFlow approach to automate publication workflows for scientific data. The PubFlow workflow management system is based on established technology. We integrate institutional repository systems (based on EPrints) and world data centers (in marine science). PubFlow collects provenance data automatically via our monitoring framework Kieker. Provenance information describes the origins and the history of scientific data in its life cycle, and the process by which it arrived. Thus, provenance information is highly relevant to repeatability and trustworthiness of scientific results. In our evaluation in marine science, we collaborate with the GEOMAR Helmholtz Centre for Ocean Research Kiel.

WAIS seminar: Application Performance Monitoring and Architecture Discovery with Kieker

Wednesday 23rd April 2014 Speaker(s): Willi Hasselbring Organiser: Leslie Carr Time: 23/04/2014 14:00-15:00 Location: B32/3077 File size: 802Mb Abstract The internal behavior of large-scale software systems cannot be determined on the basis of static (e.g., source code) analysis alone. Kieker provides complementary dynamic analysis capabilities, i.e., monitoring/profiling and analyzing a software system's runtime behavior. Application Performance Monitoring is concerned with continuously observing a software system's performance-specific runtime behavior, including analyses like assessing service level compliance or detecting and diagnosing performance problems. Architecture Discovery is concerned with extracting architectural information from an existing software system, including both structural and behavioral aspects like identifying architectural entities (e.g., components and classes) and their interactions (e.g., local or remote procedure calls). In addition to the Architecture Discovery of Java systems, Kieker supports Architecture Discovery for other platforms, including legacy systems, for instance, inplemented in C#, C++, Visual Basic 6, COBOL or Perl. Thanks to Kieker's extensible architecture it is easy to implement and use custom extensions and plugins. Kieker was designed for continuous monitoring in production systems inducing only a very low overhead, which has been evaluated in extensive benchmark experiments.

Posibilidades y límites de la integración de la formación general y la formación profesional.

Se realiza una investigación en cuanto a los proyectos modelo, para la integración de la enseñanza general y profesional en la enseñanza secundaria de segundo ciclo en la República Federal de Alemania en los años setenta. Se presenta la visión de un pedagogo de la República Democrática de Alemania que considera el desarrollo político-social en la República Federal de Alemania desde el principio de los años setenta teniendo en cuenta las siguientes circunstancias: las observaciones sobre la necesidad histórica y los propósitos generales del proyecto modelo; el esbozo de las innovaciones en tres prototipos de investigación en Baden-Württemberg, Renania del Norte-Westfalia y Bremen; y estimación de las ventajas y los límites del proyecto de integración en la Alemania Federal. Se abarca también la problemática de la integración en la República Federal de Alemania desde posiciones socialreformistas, liberales y conservadoras.

A aprendizagem cooperativa como estratégia promotora de inclusão no 1º Ciclo

Deste Trabalho de projeto faz parte uma intervenção junto de uma turma que inclui um aluno considerado com necessidades educativas especiais. A intervenção ocorreu numa turma do 1º ano de escolaridade, numa escola de uma cidade do Alto Alentejo, onde está o aluno desencadeador da nossa ação, diagnosticado com a Síndrome de Prader-Willi. Considerando que a intervenção necessita de ser fundamentada em pressupostos teóricos que sustentem as opções realizadas, no enquadramento teórico são tratados os temas: inclusão, organização e funcionamento da educação especial, aprendizagem cooperativa e estratégias na sala de aula e por último a síndrome de Prader-willi. Relativamente ao enquadramento metodológico, atendendo ao facto da investigação ser realizada numa turma onde vamos intervir, leva a que se trate de uma investigação em que a componente reflexiva teve um papel decisivo em todas as fases do trabalho, tendo-se optado por uma metodologia qualitativa assente nos princípios da investigação-ação. Utilizámos diversos métodos para a recolha de dados, nomeadamente a análise documental, a observação naturalista, a entrevista e a sociometria, o que nos permitiu recolher várias perspetivas sobre o mesmo contexto e proceder a cruzamentos entre elas. Da caracterização da turma, do aluno e dos contextos, partimos para uma intervenção estruturada, numa dinâmica de planificação, ação, avaliação e reflexão, geradora de práticas educativas diferenciadas e inclusivas. Pretendemos, com a intervenção, criar uma dinâmica cooperativa e de colaboração no grupo da turma, para que se alcance uma situação de inclusão educativa, em que os alunos aprendem todos e com todos, para conseguirem obter sucesso educativo. Os resultados obtidos indicam-nos que o aluno está incluído e que ao longo das sessões de trabalho foi mantendo um nível de interação mais positivo com os colegas. As atividades desenvolvidas tiveram impacto sobre todos os alunos e não apenas sobre o aluno desencadeador da ação.

Geostatistical radar-raingauge combination with nonparametric correlograms: methodological considerations and application in Switzerland

Modelling spatial covariance is an essential part of all geostatistical methods. Traditionally, parametric semivariogram models are fit from available data. More recently, it has been suggested to use nonparametric correlograms obtained from spatially complete data fields. Here, both estimation techniques are compared. Nonparametric correlograms are shown to have a substantial negative bias. Nonetheless, when combined with the sample variance of the spatial field under consideration, they yield an estimate of the semivariogram that is unbiased for small lag distances. This justifies the use of this estimation technique in geostatistical applications. Various formulations of geostatistical combination (Kriging) methods are used here for the construction of hourly precipitation grids for Switzerland based on data from a sparse realtime network of raingauges and from a spatially complete radar composite. Two variants of Ordinary Kriging (OK) are used to interpolate the sparse gauge observations. In both OK variants, the radar data are only used to determine the semivariogram model. One variant relies on a traditional parametric semivariogram estimate, whereas the other variant uses the nonparametric correlogram. The variants are tested for three cases and the impact of the semivariogram model on the Kriging prediction is illustrated. For the three test cases, the method using nonparametric correlograms performs equally well or better than the traditional method, and at the same time offers great practical advantages. Furthermore, two variants of Kriging with external drift (KED) are tested, both of which use the radar data to estimate nonparametric correlograms, and as the external drift variable. The first KED variant has been used previously for geostatistical radar-raingauge merging in Catalonia (Spain). The second variant is newly proposed here and is an extension of the first. Both variants are evaluated for the three test cases as well as an extended evaluation period. It is found that both methods yield merged fields of better quality than the original radar field or fields obtained by OK of gauge data. The newly suggested KED formulation is shown to be beneficial, in particular in mountainous regions where the quality of the Swiss radar composite is comparatively low. An analysis of the Kriging variances shows that none of the methods tested here provides a satisfactory uncertainty estimate. A suitable variable transformation is expected to improve this.
