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...
Startup Metrics That Tech Entrepreneurs Need to Know
2020
Metrics can be used by firms to make more objective decisions based on data. Software startups in particular are characterized by the uncertain or even chaotic nature of the contexts in which they operate. Using data in the form of metrics can help software startups to make the right decisions amid uncertainty and limited resources. However, whereas conventional business metrics and software metrics have been studied in the past, metrics in the specific context of software startups have not been studied. In this chapter, we present the results of a multivocal literature review to offer you 118 metrics practitioner experts think software startups should measure. These metrics can give you id…
A low cost and easy re-configurable instrument for power quality survey
2004
In this document the development of a low cost and user friendly PC-based instrument for power quality measurement is proposed, according to IEC 61000-4-7 and standard IEC 61000-4-30. It is an easily re-configurable instrument able to measure harmonics, interharmonics and amplitude disturbances and supply unbalance. In order to verify its accuracy, the instrument has been tested according standard test procedures, by means of a built-up calibration test bench.
Ranking of Brain Tumour Classifiers Using a Bayesian Approach
2009
This study presents a ranking for classifers using a Bayesian perspective. This ranking framework is able to evaluate the performance of the models to be compared when they are inferred from different sets of data. It also takes into account the performance obtained on samples not used during the training of the classifiers. Besides, this ranking assigns a prior to each model based on a measure of similarity of the training data to a test case. An evaluation consisting of ranking brain tumour classifiers is presented. These multilayer perceptron classifiers are trained with 1H magnetic resonance spectroscopy (MRS) signals following a multiproject multicenter evaluation approach. We demonstr…
The Monitoring and Advisory Functions of Corporate Boards
2018
The main objective of this chapter is to investigate the effects of advisory directors’ presence on the board’s overall effectiveness in value creation. To achieve this purpose, we first explore the channels through which this advisory measure influences firm value. Thus, the results suggest that the presence of at least one independent director principally committed to advising duties on the board leads to an increase in corporate innovation and a better acquisition performance. We then examine the effect of this measure on firm value. Our findings highlight that the presence of advisory directors on the board is associated with a significant increase in firm value, especially for highly i…
