21	Using the Media as a Means to Develop Students’ Statistical Concepts Kemp, Marian 02 May 2012 (has links) (PDF) In this era of increasingly fast communication people are being exposed to quantitative information, from national and international sources, through a range of media including newspapers, magazines, television, radio, pod-casts, YouTube and other areas of the Internet. Contexts include health statistics, environmental issues, traffic statistics, wars, gun laws and so on. It is becoming more and more important that citizens are able to critically read and interpret this information, and to do so requires an understanding of statistical concepts. Research has shown that students are motivated and engaged in learning through the use of authentic, real life tasks. The media provides current information, which can be used to help develop both students’ awareness of how social issues are constructed as well as vital statistical concepts. This paper proposes that secondary school students\' application of a model for statistical analysis to material taken from media sources, enhances their understanding of statistical concepts. This model, called the Five Step Framework, is described and exemplified for the particular context of opinion polling.

24	Validation of the German Five-Factor Narcissism Inventory and Construction of a Brief Form Using Ant Colony Optimization Jauk, Emanuel, Olaru, Gabriel, Schürch, Eva, Back, Mitja D., Morf, Carolyn C. 06 June 2024 (has links) Narcissism is a multifaceted construct commonly conceptualized as comprising grandiose and vulnerable aspects in a two-factor model. While the manifold correlates of these aspects imposed a challenge for research on the structure of narcissism, recent models converge in a three-factor structure of agentic-extraverted, antagonistic, and neurotic aspects, capturing variance in different conceptualizations and correlates of narcissism. We construct and validate a German adaptation of the Five-Factor Narcissism Inventory (FFNI), a measure assessing these aspects based on the Five-Factor Model. In eight samples (N = 2,921), we found the German FFNI to align with both, two- and three-factor models. The factors display good criterion validity with other narcissism measures, (non-)clinical personality dimensions, interpersonal styles, and (mal-)adaptive adjustment. Neurotic and antagonistic narcissism discriminated between individuals with/without mental disorder diagnoses, and displayed a characteristic profile in incarcerated offenders. Since the FFNI is comprehensive but long, we constructed a 30-item brief form (FFNI-BF) optimizing the internal structure and external validity using ant colony optimization. The FFNI-BF displayed good psychometric characteristics and similar, in certain aspects even advantageous criterion validity. We conclude that the German FFNI validly measures key aspects of narcissism, and the FFNI-BF captures these in a concise manner. info:eu-repo/classification/ddc/150 ddc:150 info:eu-repo/classification/ddc/610 ddc:610
25	Entwurf, Herstellung und Charakterisierung von GaN/AlGaN/GaN High Electron Mobility Transistoren für Leistungsanwendungen im GHz-Bereich Wächtler, Thomas 28 December 2005 (has links) High Electron Mobility Transistoren (HEMTs), basierend auf dem Materialsystem GaN/AlGaN/GaN, wurden entworfen, hergestellt und elektrisch charakterisiert. Für das Maskendesign kam das CAD-Programm LasiCAD zum Einsatz. Das Design umfasste bis zu sechs Lithographieebenen. Die Herstellung der Bauelemente geschah unter Reinraumbedingungen und unter Nutzung einer vorhandenen Technologie für Transistoren mit kleiner Gate-Peripherie (Doppelgate-Transistoren), die teilweise optimiert wurde. Daneben wurden Prozesse zur Herstellung von Multifinger-HEMTs entwickelt, wobei die Metallisierung der Drainkontakte mittels Electroplating von Gold vorgenommen wurde. Zur elektrischen Charakterisierung der Bauelemente wurden sowohl Gleichstromcharakteristiken, d.h. die Ausgangskennlinienfelder und Verläufe der Steilheit, als auch das Großsignalverhalten für cw-Betrieb bei 2 GHz gemessen. Dabei zeigten die Transistoren eine auf die Gatebreite bezogene Ausgangsleistungsdichte von mehr als 8 W/mm und eine Effizienz größer als 40%, einhergehend mit vernachlässigbarer Drainstromdispersion der unpassivierten Bauelemente. info:eu-repo/classification/ddc/620 ddc:620 Drei-Fünf-Halbleiter Elektronisches Bauelement Galliumnitrid Großsignalverhalten HEMT Heterostruktur Heterostruktur-Bauelement Hochfrequenztechnik Kleinsignalverhalten Metall-Halbleiter-Kontakt Mikroelektronik Molekularstrahlepitaxie Wide-gap-Halbleiter GaN/AlGaN/GaN High Electron Mobility Transistor LasiCAD MBE Maskenentwurf
