Equivalence of paper and pencil vs internet forms of the ZKPQ-50-CC in Spanish and French samples

This study was designed to check for the equivalence of the ZKPQ-50-CC (Spanish and French versions) through Internet on-line (OL) and paper and pencil (PP) answer format. Differences in means and devia- tions were significant in some scales, but effect sizes are minimal except for Sociability in the Spanish sample. Alpha reliabilities are also very similar in both versions with no significant differences between formats. A robust factorial structure was found for the two formats and the average congruency coefficients were 0.98. The goodness-of-fit indexes obtained by confirmatory factorial analysis are very similar to those obtained in the ZKPQ-50-CC validation study and they do not differ between the two formats. The multi-group analysis confirms the equivalence among the OL-PP formats in both countries. These results in general support the validity and reliability of the Internet as a method in investigations using the ZKPQ-50-CC.

Wählen per Internet verändert die Schweiz

Der Autor befasst sich mit dem Thema e-Voting am Beispiel der Schweiz. Umwählen zu gehen, begibt sich der Bürger auf Wählerseiten im Internet. Dort beantwortet er zuerst 10 Fragen zu bedeutsamen politischen Themen. Je nach seinen Antworten werden die dafür politisch eintretenden Kandidaten vorgestellt. Der Wähler kann sich nun detailliert über sie und ihre politischen Positionen informieren und dann entscheiden, welchem Politiker er seine Stimme gibt. Voraussetzung hierfür ist, dass die Kandidaten präzise Angaben über ihre Person und die von ihnen vertretene Politik im Internet zugänglich machen, da sie ansonsten auf den Wahlseiten nicht zugelassen würden und somit ihre Chancen, gewählt zu werden, minimieren würden. Hat der Bürger sich festgelegt, schickt er das Dokument zur Auswertung an einen Server des Staates, der dann innerhalb von Stunden das neue Wahlergebnis präsentieren könnte. Die Wahlseiten selbst werden wahrscheinlich nicht vom Staat kontrolliert, da die Regierung diese manipulieren könnte. Wenn aber die Gestaltung der Seiten in private Hand gelegt wird, besteht die Gefahr, dass die Listen nicht als offizielle Wahllisten anerkannt werden. Hier besteht also noch Klärungsbedarf. Ein klarer Vorteil solcher Wahlseiten ist, dass die Ziele und Interessen der Politiker noch transparenter werden. Das Internet bietet dem Bürger die Möglichkeit, seine persönlichen Interessen mit denen der Politiker zu vergleichen und sich dann nach einem Abwägunsprozess zu entscheiden. ,,In einigen Jahren werden hier zu Lande Wahlurnen ganz verschwinden", prophezeit der Autor und verweist auf die Arbeit einer Projektgruppe, die die noch offenen Fragen des E-Votings klären will.

Chronically connected? Internet use among adolescents with chronic conditions.

Little is known about Internet use among adolescents with chronic conditions (CCs). Our results indicate that CC females, but not males, are more likely to be heavy Internet users than their peers. CC youths are also more likely to visit health-related web sites, but less frequently than other sites.

Droit d'auteur sur internet: le cadre juridique actuel est-il suffisant?

Selon un rapport du Conseil fédéral publié en novembre 2011, le droit d'auteur actuel serait adapté à l'ère numérique. Un examen critique de cette conclusion montre qu'il n'en est rien. En effet, le droit positif ne peut pas être mis en oeuvre, pour des raisons qui dépassent de loin la problématique de la protection des données ayant fait l'objet de l'arrêt Logistep. D'une part, il est difficile de prouver les atteintes au droit d'auteur sur internet. D'autre part, les sanctions civiles pécuniaires d'infractions au droit d'auteur sont peu adaptées lorsque des oeuvres sont mises en ligne à titre gratuit.

Trace element partitioning in HP-LT metamorphic assemblages during subduction-related metamorphism, Ile de Groix, France: a detailed LA-ICPMS study

Devolatilization reactions and subsequent transfer of fluid from subducted oceanic crust into the overlying mantle wedge are important processes, which are responsible for the specific geochemical characteristics of subduction-related metamorphic rocks, as well as those of arc magmatism. To better understand the geochemical fingerprint induced by fluid mobilization during dehydration and rehydration processes related to subduction zone metamorphism, the trace element and rare earth element (REE) distribution patterns in HP-LT metamorphic assemblages in eclogite-, blueschist- and greenschist-facies rocks of the Ile de Groix were obtained by laser ablation inductively coupled plasma mass spectrometry (LA-ICPMS) analysis. This study focuses on 10 massive basic rocks representing former hydrothermally altered mid-ocean ridge basalts (MORB), four banded basic rocks of volcano-sedimentary origin and one micaschist. The main hosts for incompatible trace elements are epidote (REE, Th, U, Pb, Sr), garnet [Y, heavy REE (HREE)], phengite (Cs, Rb, Ba, B), titanite [Ti, Nb, Ta, REE; HREE > LREE (light REE)], rutile (Ti, Nb, Ta) and apatite (REE, Sr). The trace element contents of omphacite, amphibole, albite and chlorite are low. The incompatible trace element contents of minerals are controlled by the stable metamorphic mineral assemblage and directly related to the appearance, disappearance and reappearance of minerals, especially epidote, garnet, titanite, rutile and phengite, during subduction zone metamorphism. Epidote is a key mineral in the trace element exchange process because of its large stability field, ranging from lower greenschist- to blueschist- and eclogite-facies conditions. Different generations of epidote are generally observed and related to the coexisting phases at different stages of the metamorphic cycle (e.g. lawsonite, garnet, titanite). Epidote thus controls most of the REE budget during the changing P-T conditions along the prograde and retrograde path. Phengite also plays an important role in determining the large ion lithophile element (LILE) budget, as it is stable to high P-T conditions. The breakdown of phengite causes the release of LILE during retrogression. A comparison of trace element abundances in whole-rocks and minerals shows that the HP-LT metamorphic rocks largely retain the geochemical characteristics of their basic, volcano-sedimentary and pelitic protoliths, including a hydrothermal alteration overprint before the subduction process. A large part of the incompatible trace elements remained trapped in the rocks and was recycled within the various metamorphic assemblages stable under changing metamorphic conditions during the subduction process, indicating that devolatilization reactions in massive basic rocks do not necessarily imply significant simultaneous trace element and REE release.

Acompanhamento das bibliotecas brasileiras na Internet

A biblioteca virtual no Brasil é uma alternativa para se acessar informação através da Internet na Biblioteca Nacional, em bibliotecas especializadas, universitárias, públicas e escolares. Um levantamento preliminar, realizado pelo IBICT, mostra a distribuição de bibliotecas virtuais por estado e sua presença na Internet. Os principais produtos e serviços disponíveis são o acesso a apontadores, obras digitalizadas, catálogos e informações institucionais. A interligação das diversas bibliotecas minimiza esforços e evita duplicação de trabalho.
