Brief emotional eating scale : A multinational study of factor structure, validity, and invariance
2023
Emotional eating or the tendency to eat in response to emotional states can be assessed using self-report measures. The Emotional Eating Scale-II is a commonly used and reliable instrument that measures the desire to eat in response to a range of unpleasant and pleasant emotions. The current study aimed to corroborate the validity of the EES-II and expand its utility by investigating its dimensionality and testing its measurement invariance in samples from English-speaking and non-English-speaking countries. Convergent and predictive validity in respect of food craving, eating, and health indicators were also examined. This cross-national study included a total of 2485 adult participants re…
Centre characteristics and procedure-related factors have an impact on outcomes of allogeneic transplantation for patients with CLL: a retrospective …
2017
Abstract Introduction:Even in the era of novel targeted therapies for the treatment of Chronic Lymphocytic Leukemia (CLL) patients, such as BTK, PI3K and BCL2 inhibitors, allogeneic hematopoietic stem cell transplantations (alloHCT) will remain an important treatment option for a subset of patients with very high risk CLL. The current study focused on the impact of center and procedure-related factors on outcomes after alloHCT, taking into account the impact of patient- and disease-related risk factors. Patients and Methods:Data of 684 CLL patients who received a first alloHCT between 2000 and 2011 were analyzed. Their data were collected as part of the EBMT CLL Data Quality Initiative. Out…
Validierung der Messung gesundheitsbezogener Lebensqualität mittels des Short-Form-Health-Survey-12 (SF-12 Version 2.0) in einer deutschen Normstichp…

Validation of the Short-Form-Health-Survey-12 (SF-12 Version 2.0) assessing health-related quality of life in a normative German sample Objectives: Convergent and divergent validation of the Short-Form-Health-Survey-12 assessing HRQoL by analyzing its associations with depressiveness (PHQ-9), social support (OSS-3) and satisfaction with life (SWLS). Methods: A normative German sample (N = 2.524) was analyzed using correlation, regression as well as confirmatory factor analysis and structural equation modelling for ordinal data. Results: The SF-12-scale Mental Health is associated most strongly with the validation criteria (PHQ: r[scales/constructs] = -.73/-.88, OSS-3: r = .35/.55, SWLS: r =…
Study Approaches in Higher Education Mathematics : Investigating the Statistical Behaviour of an Instrument Translated into Norwegian

Intellectual capital, organisational performance and competitive advantage
2019
At present, the role of intellectual capital in organisations is significantly more important than in the past owing to the transition from an economy based on assets to another based on knowledge. The value of intangible assets increases as that of tangible assets decreases; this allows organisations, which prioritise intellectual capital, to produce competitive advantages and achieve better performance. The purpose of this paper is to ascertain if human capital, structural capital and relational capital have a positive influence on the organisational performance of medium-sized firms in the Mexican manufacturing sector. Moreover, it is analysed if competitive advantage mediates the relati…
Talent management and organizational commitment: the partial mediating role of pay satisfaction
2020
PurposeThe purpose of this study is to better understand the role of pay satisfaction and employee perception of talent management in business loyalty strategies, which implies considering both economic and non-economic variables in order to achieve organizational success.Design/methodology/approachResults from a survey of 198 workers were analysed using structural equation modelling (SEM) based on three constructs (confirmatory factor analysis, CFA). The scales used were: employee perception of talent management, pay satisfaction, and organizational commitment. Pay satisfaction acts as a mediating variable in the significant relationship between the perception of talent management and orga…
Correlation, hierarchies, and networks in financial markets
2010
We discuss some methods to quantitatively investigate the properties of correlation matrices. Correlation matrices play an important role in portfolio optimization and in several other quantitative descriptions of asset price dynamics in financial markets. Specifically, we discuss how to define and obtain hierarchical trees, correlation based trees and networks from a correlation matrix. The hierarchical clustering and other procedures performed on the correlation matrix to detect statistically reliable aspects of the correlation matrix are seen as filtering procedures of the correlation matrix. We also discuss a method to associate a hierarchically nested factor model to a hierarchical tre…
Key levels for knowledge creation and management: which is the ontological locus for learning in Spanish manufacturing firms?
2013
This paper aims to highlight two core issues related to knowledge management and organisational learning. First deals with the ontological support-knowledge creation relationship. Secondly, the comparison between Crossan et al. (1999) and Nonaka and Takeuchi (1995) models: on what ontological supports knowledge is created? Individuals, groups and organisation: are they independent or do they interact with each other? Is individual level swallowed up by the group [as Nonaka and Takeuchi (1995) seems to suggest], leading to groups and organisation as unique ontological levels? The empirical study draws those ontological levels in large manufacturing Spanish firms. It identifies (via explorato…
Towards a methodology to assess organizational learning capability
2011
PurposeThe present study aims to revalidate a measurement scale for organizational learning capability in the context of university faculty members. This is a particularly relevant context because it deals with knowledge‐intensive services. Following Chiva et al., organizational learning capability was conceptualized as a second factor construct including five dimensions: experimentation, risk taking, interaction with the external environment, dialogue and participative decision making.Design/methodology/approachData were collected from the Instituto Tecnológico de Costa Rica, a leading university in Costa Rica. The survey was addressed to faculty members. A total of 795 valid questionnaire…
Measuring organisational learning capability among the workforce
2007
PurposeThe present study sets out to propose and validate a measurement scale that aims to capture the organisational capability to learn, based on a comprehensive analysis of the facilitating factors for learning. The organisational learning capability scale consists of 14 items grouped into five dimensions: experimentation, risk taking, interaction with the external environment, dialogue, and participative decision making.Design/methodology/approachData were collected from eight Spanish ceramic tile manufacturers. The survey was addressed to shop floor workers. A total of 157 valid questionnaires were obtained, representing a response rate of 61 per cent. Using confirmatory factor analysi…
