Adapting and Validating the Collegiate Learning Assessment to Measure Generic Academic Skills of Students in Germany: Implications for International …
2018
Starting in 2015, a German research team from the program Modeling and Measuring Competencies in Higher Education (KoKoHs), in collaboration with the US Council for Aid to Education (CAE), adapted and validated the Collegiate Learning Assessment (CLA+) for the German language and cultural context to measure generic higher-order cognitive skills of university students and graduates in Germany. In this chapter, the conceptual and methodological background, the framework of the adaptation and validation study, as well as preliminary results are presented. Finally, findings are discussed critically, and future challenges and perspectives are explored.
An Analysis of the Drivers of Microfinance Rating Assessments
2012
Rating assessments of microfinance institutions (MFIs) are claimed to measure a combination of creditworthiness, trustworthiness, and excellence in microfinance. Using a global data set covering reports from 304 microfinance institutions, this study suggests that these ratings are mainly driven by size, profitability, and risk. The overall results suggest that microfinance ratings convey information similar to that communicated by traditional credit ratings. All results are remarkably consistent across rating agencies. The determinants of the rating grades are found to be the same in all subsamples.
Performance Measurement and Outperformance Tests
2017
This chapter explains how to evaluate the performance of a trading strategy and how to carry out a statistical test of the hypothesis that a moving average trading strategy outperforms the corresponding buy-and-hold strategy. In particular, it argues that there is no unique performance measure, reviews the most popular performance measures, and points to the limitations of these measures. The chapter then surveys the parametric methods of testing the outperformance hypothesis and the current “state of the art” non-parametric methods.
New Trend to Evaluate the Management of Companies: An Application of the Methodologies of Radar Chart
2014
The methodology of radar chart arises as an alternative answer to traditional measures on management of companies' activities. How to answer to market disruptions? It is a question solved by this methodology, which allows us to measure the management of each area represented on a radar chart by applying principles of plane geometry. In this methodology, a decision on a management area affects to the result of other areas because it has a multidirectional effect. Its application is carried out on a Spanish company.
Psychometric Properties of an Emotional Adjustment Measure
2007
Item response theory (IRT) provides valuable methods for the analysis of the psychometric properties of a psychological measure. However, IRT has been mainly used for assessing achievements and ability rather than personality factors. This paper presents an application of the IRT to a personality measure. Thus, the psychometric properties of a new emotional adjustment measure that consists of a 28-six graded response items is shown. Classical test theory (CTT) analyses as well as IRT analyses are carried out. Samejima's (1969) graded-response model has been used for estimating item parameters. Results show that the bank of items fulfills model assumptions and fits the data reasonably well,…
Does model consistency in business model innovation matter? A contingency-based approach
2017
Successful business model innovation requires managers to come up not only with new, but also with viable business models. To this end, it has been argued that business model consistency plays a vital role, as the internal fit of business model elements can generate reinforcing effects, thereby influencing performance and competitive advantage. Little research has been conducted to measure consistency and confirm these effects, especially within business model innovation. We tackle this issue by developing and testing a measurement of business model consistency, and investigate its relationship with business model innovation and its performance. We find evidence supporting the positive effe…
La Bibliometría en la evaluación de la actividad científica
2018
El análisis y la evaluación de la información y el conocimiento resultante de la actividad científica es un elemento imprescindible para todos los programas de investigación pública, tecnología y desarrollo que se implementan en una sociedad; y es allí donde la Ciencia de la Información brinda una ayuda inestimable, al desarrollar técnicas e instrumentos para medir la producción de conocimiento y su transformación en bienes.La cuantificación de las publicaciones es el elemento básico de la mayor parte de los estudios bibliométricos, mientras que la de las citas puede usarse directamente como medida de la repercusión o importancia de una publicación, o de las publicaciones de una persona, in…
A Short Measure of Acceptability of Intimate Partner Violence Against Women: Development and Validation of the A-IPVAW-8 Scale
2021
Attitudes of acceptability of intimate partner violence against women (IPVAW) are considered one of the main risk factors of this type of violence. The aim of this study is to develop and validate a short version of the acceptability of IPVAW scale, the A-IPVAW-8, for large scale studies where space and time are limited. A panel of experts were asked to assess item content validity. Two samples were recruited to assemble an 8-item short version of the scale using automated test assembly, and to reassess the psychometric properties of the A-IPVAW-8 in an independent sample. Results showed that the A-IPVAW-8 had adequate internal consistency (α = .72-.76, ω = .73-.81), a stable one-factor la…
“Let’s make lots of money”: the determinants of performance in the recorded music sector
2017
This research analyzes the performance of 467 record labels in eight European countries over a period of 13 years (2003-2015). The main goal is to explain a relative measure of profitability in terms of observed variables, although the nature of the dataset also allows us to include non-observed firm and country effects. To this end alternative models are estimated and three main research questions are tested, namely: (1) the effect of the dual structure of the recorded music market, in which a competitive segment and an oligopoly coexist; (2) the extent and source of the volatility of profits in record labels; and (3) the nonlinear impact of size on performance.
Evaluating a Technology-Based Assessment (TBA) to Measure Teachers’ Action-Related and Reflective Skills
2019
Teaching performance can be assessed validly only if the assessment involves an appropriate, authentic representation of real-life teaching practices. Different skills interact in coordinating teac...
