title: Fission Track Data and Ages of Apatite and U-Pb Isotopic Data and Ages of Igneous and Detrital Zircon from Selected Rocks from the Lake Clark and Lake Iliamna Region of South-Central Alaska

description: This data set contains fission track data and associated ages of apatite from igneous and sedimentary rocks, U-Pb isotopic data and associated ages of zircon from a subset of the igneous rock samples, and U-Pb isotopic data and associated ages of detrital zircon from a subset of the sedimentary rock samples. All samples were collected from the region surrounding Lake Clark and Lake Iliamna in southwestern Alaska. All samples were collected as part of geological mapping and research conducted in 2008 and funded by the U.S. Geological Survey Mineral Resources External Research Program. Apatite and zircon grains were separated and analyzed by Apatite to Zircon, Inc. (A2Z). All analyses were conducted in 2009 using standard fission track dating techniques and laser-ablation-inductively-coupled-plasma-mass spectrometry (LA-ICP-MS) techniques.

Prinzipiell versucht ein Interviewer face-to-face-Interviews mit allen Haushaltsmitgliedern durchzuführen, die 16 Jahre alt oder älter sind. Zusätzlich wird eine Person (Haushaltsvorstand) gebeten, einen Haushaltsfragebogen zu beantworten, einschließlich Fragen zur Wohnsituation, Kosten, verschiedenen Einkommensquellen, sowie Fragen zu im Haushalt lebenden Kindern unter 16 Jahren (z.B. Besuch des Kindergartens, der Grundschule etc.)
description: The interview methodology of the SOEP is based on a set of pre-tested questionnaires for households and individuals. Principally an interviewer tries to obtain face-to-face interviews with all members of a given survey household aged 16 years and over. Additionally one person (head of household) is asked to answer a household related questionnaire covering information on housing, housing costs, and different sources of income. This covers also some questions on children in the household up to 16 years of age, mainly concerning attendance at institutions (kindergarten, elementary school, etc.)

description: Die fünfte Erhebung von PISA im Jahr 2012 in Deutschland wurde von einer Arbeitsgruppe am Zentrum für internationale Bildungsvergleichsstudien (ZIB e. V.) durchgeführt. Auch in dieser PISA-Erhebungswelle galt es zu klären, wie gut 15-jährige Schülerinnen und Schüler auf die Anforderungen der Wissensgesellschaft und auf lebenslanges Lernen vorbereitet sind. Die Testaufgaben von PISA richteten sich demzufolge nicht an spezifischen Lehrplänen aus, sondern an Wissen und Fähigkeiten, die im privaten und beruflichen Alltag zum Einsatz und zum Erwerb von Wissen benötigt werden. Wie in den vorherigen PISA-Studien bearbeiteten die Schülerinnen und Schüler Aufgaben aus den Bereichen Lesen, Mathematik, Naturwissenschaften und Problemlösen. Der Schwerpunktbereich in PISA 2012 war nach 2003 zum zweiten Mal die mathematische Grundbildung. Neben den Kompetenzen von Schülerinnen und Schülern wurden wie auch bei den bisherigen PISA-Studien weitere Daten über Einstellungen der Schülerinnen und Schüler, über den Schulkontext, über demographische Merkmale und Angaben über den sozialen, kulturellen und familiären Hintergrund erhoben. Darüber hinaus dienten Fragebögen für die Lehrkräfte, Schulleitungen und Eltern der Erfassung weiterer relevanter Hintergrundmerkmale.
description: TThe fifth survey of PISA in 2012 in Germany was carried out by a working group at the Centre for International Student Assessment (ZIB e.V.). PISA aims to measure how well students at age 15 are prepared to meet the challenges of today's knowledge societies and lifelong learning. Thus, the PISA test items are not directly linked to national school curricula but are designed to assess the skills and competences required for the acquisition of knowledge and its application to real-life situations. In this study, as in the previous PISA surveys, students were tested in the domains of reading literacy, mathematical literacy, scientific literacy and problem solving. In PISA 2012 the focus was on mathematical literacy for the second time since 2003. In addition to assessing students' competencies, PISA 2012, like its forerunners, gathered information about students' attitudes, their school context, demographic characteristics and students' social, cultural and family background. Furthermore, questionnaires for teachers, school principals and parents were used for the detection of other relevant background characteristics.

Sie dient der systematischen Überprüfung des Erreichens der Bildungsstandards für die Fächer Mathematik und die Naturwissenschaften in den Ländern der Bundesrepublik Deutschland. Insgesamt nahmen an der Untersuchung ungefähr 44.500 Schülerinnen und Schüler der 9. Jahrgangsstufe teil. Im Fach Mathematik wurden Aufgaben zu allen allgemeinen und inhaltsbezogenen mathematischen Kompetenzen getestet und in einem Globalwert für mathematische Kompetenz zusammengefasst. In den Naturwissenschaften hingegen bearbeiteten die Schülerinnen und Schüler Aufgaben zur Erfassung ihrer Kompetenzen in den Bereichen „Fachwissen“ und „Erkenntnisgewinnung“ in den Fächern Biologie, Chemie und Physik (siehe auch Bildungsstandards in den Fächern). Neben den Kompetenztests kamen auch Fragebögen für Schülerinnen und Schüler, Eltern, Fachlehrkräfte und die Schulleitungen zum Einsatz. Diese dienten der Erfassung schulischer und außerschulischer Lerngelegenheiten und der Rahmenbedingungen, die zur Optimierung von Lernprozessen genutzt werden können. Außerdem wurden Indikatoren für die Lesekompetenz und die kognitiven Grundfähigkeiten der Schülerinnen und Schüler erhoben.
description: The National Assessment Study in Mathematics and Science 2012 (IQB Ländervergleich Mathematik und Naturwissenschaften 2012) is a nationwide large-scale assessment commissioned by the Standing Conference of the Ministers of Education and Cultural Affairs of the Länder (KMK) in the Federal Republic of Germany. The study was designed to assess students’ achievement in mathematics, biology, chemistry and physics and to evaluate to which extent they meet educational standards in the German Länder. About 44,500 grade 9 students participated in the study. In mathematics, all general competencies and content areas were tested and averaged to obtain a global score of mathematics proficiency. In Science, in turn, only the two content areas “content knowledge” and “scientific inquiry” were assessed for biology, chemistry and physics (see also Educational standards by subject). In addition to achievement tests, the study used questionnaires for students, parents, teachers and principals to assess curricular and extracurricular learning opportunities and to investigate which structures can be used to optimize learning processes. Indicators of the students’ reading abilities and basic cognitive abilities were also assessed.

Der ifo Investitionstest für das Verarbeitende Gewerbe wird seit 1955 halbjährlich (im Frühjahr und im Herbst) vom ifo Institut erhoben. Kern des Fragenprogramms sind quantifizierte Angaben zu den Investitionen der jüngsten Vergangenheit, des laufenden Jahres und – im Herbst – auch des folgenden Jahres. Des Weiteren werden die Unternehmen zu ihren Investitionszielen befragt und einmal im Jahr – in der Herbsterhebung – werden sie gebeten, den Einfluss vorgegebener Faktoren (Auftragslage, Finanzierungsmöglichkeiten, Ertragslage usw.) auf Ihre Investitionstätigkeit zu beurteilen. Die Bilanzdaten der Unternehmensdatenbanken wurden mit Hilfe der Programms Matching-Software MTB (Merge Toolbox), welche am „Center for quantitative Methods and Survey Research“ der Universität Konstanz entwickelt wurde dazu gespielt.

The survey's core questions are designed to elicit quantified responses on companies' latest investments, on their investment plans for the ongoing year and, in autumn, on their investment plans for the year ahead. Companies are also asked about their investment goals, and in the autumn survey they are asked to assess the influence of specific factors (orders-in-hand, financing options, financial position etc.) on their investment activity. The financial variables were merged by using the matching software MTB (Merge Toolbox) developed at the Center for Quantitative Methods and Survey Research of the University of Konstanz.
