This book showcases a large variety of multiple criteria decision applications (MCDAs), presenting them in a coherent framework provided by the methodology chapters and the comments accompanying each case study. The chapters describing MCDAs invite the reader to experiment with MCDA methods and perhaps develop new variants using data from these case studies or other cases they encounter, equipping them with a broader perception of real-world problems and how to overcome them with the help of MCDAs.

jMetrik is a computer program for implementing classical and modern psychometric methods. It is designed to facilitate work in a production environment and to make advanced psychometric procedures accessible to every measurement practitioner. Applied Measurement with jMetrik reviews psychometric theory and describes how to use jMetrik to conduct a comprehensive psychometric analysis. Each chapter focuses on a topic in measurement, describes the steps for using jMetrik, and provides one or more examples of conducting an analysis on the topic. Recommendations and guidance for practice is provided throughout the book.

This book answers the question of how to manage service robots in brick-and-mortar dominated retail service systems to allow for key stakeholders' adoption and to foster value co-creation. It starts by demonstrating the scientific relevance of the topic as well as deriving a set of promising research questions. After introducing service-dominant logic as a theoretical research lens and elucidating service systems along with their underlying concept of value co-creation as relevant key concepts, five studies are presented. The authors findings show that understanding and differentiating between consensus, shared and idiosyncratic drivers of and barriers to the adoption of service robots in retail service systems by all key stakeholders, i.e. customers, frontstage employees, and retail managers, is crucial to be able to fully cope with the complexity inherent in the adoption of service robots in service organizations. Moreover, the designed and evaluated artifact fosters a paradigm shift from a one-time technology introduction to a continuous technology management approach including iterations of experimenting, piloting, and implementing.

This is a title in our Understanding Statistics series, which is designed to provide researchers with authoritative guides to understanding, presenting and critiquing analyses and associated inferences. Each volume in the series demonstrates how the relevant topic should be reported -- including detail surrounding what can be said, and how it should be said, as well as drawing boundaries around what cannot appropriately be claimed or inferred.
This volume addresses reliability, which is a fundamental aspect of any social science study that involves educational or psychological measurement. It not only has implications for the quality of test scores themselves,
but also any statistical analysis conducted using those scores. Topics addressed in this book include cover three different types of reliability methods and appropriate standard errors of measurement: classical test theory methods, decision consistency indices, and generalizability theory coeffcients. After a brief introduction to the topic, the author outlines how to report reliability in professional journal articles. Meyer is known for his clear, accessible writing; like all books in this series, this volume includes examples of both good and bad write-ups for methods sections of journal articles.

Diplomarbeit aus dem Jahr 2010 im Fachbereich BWL - Investition und Finanzierung, Note: 1,7, Universitat Paderborn, Sprache: Deutsch, Anmerkungen: Seit geraumer Zeit wird in der Literatur immer wieder behauptet, dass Ross' Arbitragepreistheorie (auch APT genannt) eine sinnvolle Alternative zum CAPM darstellt. Diese Behauptung wird in vorliegender Arbeit kritisch hinterfragt. Aufbau: Die Arbeit gliedert sich neben Einleitung und Schluss in zwei grosse Abschnitte: Schwachen des originaren CAPM und Die APT von Ross als alternatives Bewertungsmodell. Der erste Abschnitt das CAPM und seine Schwachen dar, der zweite Abschnitt ist der Theorie von Ross und ihren Problemen gewidmet., Abstract: Das CAPM von Sharpe, Lintner und Mossin ist als theoretisches Modell zur Erklaerung der Renditestruktur risikobehafteter Wertpapiere in seiner Funktion von zentraler Bedeutung fuer die Kapitalmarkttheorie. Ausgehend von seinen Modellannahmen ueber die Investoren, den Markt und die Renditen gelangt das CAPM zu einem intuitiv einleuchtenden Ergebnis: Fuer den Erwartungswert der Rendite eines risikobehafteten Wertpapiers gilt im Gleichgewicht, dass sich diese aus der Rendite eines risikolosen Titels zuzueglich einer Risikopraemie fuer uebernommenes nicht zerstreubares Risiko ergibt. Diese fundamentale Rendite-Risiko-Beziehung, nach der Investoren fuer zusaetzliches systematisches Risiko entlohnt werden, basiert jedoch auf einem Modellsetup, das Gegenstand kontroverser Diskussionen ist. Die Kritik betrifft im Wesentlichen zwei Bereiche des CAPM. Zum Einen wird von den Modellannahmen behauptet, dass sie nicht mit der Realitaet vereinbar waeren. Zum Anderen gibt es Einwaende gegen das Marktportfolio, welches entsprechend der obigen Modellaussage grundlegend fuer die Quanti zierung des marktbezogenen Risikos im CAPM ist. Entsprechend vieler Standardwerke der Finanzierungstheorie stellt die Arbitrage Pricing Theory (kurz: APT) von Ross neben dem CAPM einen weiteren fundamentalen Bewer
