Förderbezogene Diagnostik in Mathematik inklusive Lesen (ForMeL) (Version 1) [Datensatz]
No full text
Das Projekt ForMeL umfasst die Entwicklung, Erprobung, Evaluation und Dissemination eines
kombinierten förderorientierten Diagnostikinstruments von Mathematik- und
Lesekompetenz in inklusiven Schulen am Übergang von der Grundschule zur
Sekundarstufe I (Mentrop et al., 2025).
Der hier veröffentlichte Datensatz umfasst alle Daten aus der Hauptstudie. Diese wurde im Winter 2023/24 in 4. und 5. Schulklassen in NRW durchgeführt (N = 169). Enthalten sind die Daten zum entwickelten Diagnosetest. Dieser besteht aus 4 Themenkomplexen mit unterschiedlichen Schwierigkeitsgraden (Mentrop et al., 2025, Tab. 2). Die Reliabilitäten liegen im moderaten Bereich (zwischen α .63-.74; Mentrop et al., 2025, Tab. 1).
Zusätzlich finden sich folgende Dokumentationen:
statistische Berechnungen auf Basis des Datensatzes (Reliabilitätsanalysen, Clusterung zur Bildung von Fördertypen),
Codebook zu allen Variablen des Datensatzes,
der in ForMeL eingesetzte Diagnosetest,
eine Auswertungstabelle des Diagnosetests,
eine Auswertungsvorlage des Diagnosetests, die Lehrer*innen die Auswertung erleichtern soll.

Ask questions, get sales : close the deak and create long-term relationships / Stephan Schiffman.
No full textIncludes index.v, 168 pages ;In Ask Questions, Get Sales, the author and sales guru Stephan Schiffman helps readers boost their careers to the gold-medal level by teaching them how to strengthen their questioning skills during the sales process. The premise is simple yet effective: In order to be successful, salespeople need to change their mindset from "need-orientated" to "do-orientated". The message of the book centers around six core "do" questions: What do you do? How do you do it? When and where do you do it? Why do you do it that way? Who do you do it with? How can we help you do it better? With this indispensable guide in their briefcase, salespeople will have information at the ready to score big sales over the short term and the long term
Unemployment Benefits and Unemployment Rates of Low-Skilled and Elder Workers in West Germany: A Search Equilibrium Approach

To answer this question we estimate a version of the Burdett-Mortensen search equilibrium model and analyze how workers’ search behaviour responded to these reforms. We try both nonparametric and fully-parametric estimation methods and identify the cases in which the nonparametric approach cannot be applied. We find that the entitlement reforms are largely responsible for the increase of unemployment among unskilled workers

Measuring Vulnerability to Poverty Using Long-Term Panel Data
No full textMeasuring Vulnerability to Poverty Using Long-Term Panel Data Author & abstract Download & other version 16 References 4 Citations Related works & more Corrections Author Listed: Katja Landau (Georg-August-University Göttingen) Stephan Klasen (Georg-August-University Göttingen) Walter Zucchini (Georg-August-University Göttingen) Registered: Stephan Klasen Abstract We investigate the accuracy of ex ante assessments of vulnerability to income poverty using cross-sectional data and panel data. We use long-term panel data from Germany and apply di fferent regression models, based on household covariates and previous-year equivalence income, to classify a household as vulnerable or not. Predictive performance is assessed using the Receiver Operating Characteristics (ROC), which takes account of false positive as well as true positive rates. Estimates based on cross-sectional data are much less accurate than those based on panel data, but for Germany, the accuracy of vulnerability predictions is limited even when panel data are used. In part this low accuracy is due to low poverty incidence and high mobility in and out of poverty
Design and test of a calibration method for the calculation of metrical range valuesfor 3D light field cameras
Get PDFZiel dieser Arbeit ist, einen Algorithmus zur metrischen Kalibrierung einer Lichtfeldkamera zu implementieren und zu testen. Für die Kalibrierung wird eine Kalibriertafel mit der Lichtfeldkamera aufgenommen. Aus dem Bild der Tafel werden
die Positionen von Merkmalen extrahiert. Die so gewonnenen Punkte werden durch
ein geeignes Kameramodell projiziert, so dass eine Fehlerfunktion minimiert werden
kann.The goal of this work is to implement and test an algorithm for metrically calibrating
a light field camera. For the calibration, an image of a calibration target is taken with
the light field camera. The positions of features are extracted from this image. The
points obtained in this way are then projected through a suitable camera model, so
that an error function can be minimized

Konzeption, Implementierung und Test eines Demonstrators auf FPGA-Basis zur Datenübertragung mit Millimeterwellen-Frontends
Get PDFDiese Arbeit umfasst die Entwicklung eines Demonstrators auf FPGA-Basis für eine neue Generation von Millimeterwellen-Frontends. Zur Demonstration werden digital modulierte Signale über die Millimeterwellen-Frontends gesendet und empfangen. Teil der Entwicklung ist die Anbindung eines Sender-FPGAs an einen DAC, sowie eine Anbindung eines ADCs an einen Empfänger-FPGA. Eine Bitfehlerratenmessung wird zur Evaluierung der Frontends und der verwendeteten Modulationsarten verwendet. Im Zuge der Arbeit werden optimierte System-Generator-Module untersucht sowie alternative Modulationsarten, die mit den besonderen Eigenschaften der Millimeterwellen-Frontends arbeiten
