Refinement and validation of a comprehensive scale for measuring HR practices aimed at performance-enhancement and employee-support
2019
Abstract The purpose of this paper is to refine and validate a Human Resource practices (HRP) scale to measure employees' perceptions and test a two-tier model structured in eight practices and two bundles. In a sample of 554 employees, an EFA (Exploratory Factor Analysis) offered six factors that explained about 70% of the variance. Then, with 1647 employees (from 41 Spanish organizations), first- and second-order models were tested with Confirmatory Factor Analysis (CFA). The former encompasses eight practices. The latter grouped the practices in two bundles, one on enhancing performance and the other on supporting employees. The Cronbach's alpha, Rho coefficient (Composite Reliability Co…
Spanish validation of the Servant Leadership Short Scale for young adults and adolescents / Validación de la Escala de Liderazgo de Servicio Versión …
2017
AbstractThe aim of the current study was to validate a shortened Spanish version of the Servant Leadership Profile (SLP). In Study 1, a number of experts evaluated and reduced the original scale to 14 items and named the revised version the Servant Leadership Short Scale (SLSS). An exploratory factor analysis conducted with a sample of 1,001 students revealed two possible structure solutions, a one-factor solution and a two-correlated factor solution. Study 2 used a different sample of 456 students to examine the explored structures using confirmatory factor analysis. A one-factor solution was proposed (χ2/df = 3.4, CFI = .91, TLI = .90, RMSEA = .07, SRMR = .06). Finally, in Study 3, servan…
Et si nous arrêtions d'utiliser systématiquement l’analyse en composantes principales (PCA)? Efficacité des méthodes d’extraction de facteurs dans l’…
2014
Fabrigar et al. (1999) et, en suite Worthington et Whittaker (2006) décrivaient les limites de l’utilisation de la PCA comme méthode d’extraction de facteurs dans les procédures d’EFA. Les auteurs soulignent que l’abus de cette pratique s’explique probablement par le fait que cette méthode est présentée comme premier choix dans la plupart des logiciels d’analyse des données. L’objectif de ce travail est de montrer qu’il y a encore un excès d’utilisation dans la pratique de la PCA et, de l’autre, de donner des indications de base pour le choix d’une méthode correcte pour l’EFA. Ce travail recense les principaux travaux de recherche parus, entre 2011 et 2013, dans des revues à facteur d'impac…
Metabolic flux understanding of Pichia pastoris grown on heterogenous culture media
2014
[EN] Within the emergent field of Systems Biology, mathematical models obtained from physical chemical laws (the so-called first principles-based models) of microbial systems are employed to discern the principles that govern cellular behaviour and achieve a predictive understanding of cellular functions. The reliance on this biochemical knowledge has the drawback that some of the assumptions (specific kinetics of the reaction system, unknown dynamics and values of the model parameters) may not be valid for all the metabolic possible states of the network. In this uncertainty context, the combined use of fundamental knowledge and data measured in the fermentation that describe the behaviour…
A Survey of Teacher Perceptions of the School Psychologist's Skills in the Consultation Process An Exploratory Factor Analysis
2004
The main purpose of this study is to present the construction and validation process of an instrument designed to evaluate the professional skills of the school psychologist in the teacher consultation process. Initially, an extensive list of items was created which evaluated the characteristics of school psychologists in this area. After carrying out a pilot study and making the necessary modi.cations, we presented the scale to a sample of 157 primary and secondary public school teachers in the Valencian Community. An exploratory factor analysis was carried out on the main components, applying the corresponding varimax rotation. The results show a factorial structure made up of three comp…
Therapeutic activities and the assimilation model: A preliminary exploratory study on the Insight stage
2014
The assimilation model describes the process of change assuming that the self is enriched when there is a dialogue between nondominant voices or problematic experiences and the dominant voices. This dialogue is best seen in the Insight stage. The aim of this paper is to study the Insight stage during the assimilation process in relation to the main therapeutic activities performed by the therapist. All the Insights from the assimilation process of a patient, Maria, were analysed. In assimilation terms, Maria could be described through the nondominant voices of “dizziness,” “tiredness,” and “inability to cope with daily demands,” and through the dominant voices of “control,” “overcome and so…
University Management with Focus on Multicriteria Performance Evaluation: Illustration in the Brazilian Context
2015
Public universities have been facing situations that impel them to improvements in its management towards excellence in reaching, with quality, the objectives for which they were constituted, i.e., to offer teaching, research and extension. In this context, it is up to the managers of the universities to act proactively. The literature points out that the internal control systems are managerial tools capable of providing information for the manager’s actions in his/her activity; however we notice that the academic literature devoted to this demand is still scarce, especially as regards support for decision-making considering organizational specificities. Given the importance of the manager'…
Value co-creation process and measurement in 4.0 SMEs: An exploratory research in a B2B marketing innovation context
2021
The purpose of this exploratory research is to contribute to the lack of empirical research exploring techniques and protocols that can be used to measure the level of value obtained from using these technologies in the various marketing processes and in a business-to-business (B2B) context. By doing so, firms operating in fast changing dynamic environments can develop the right means to continuously adapt, integrate, reconfigure, and redeploy resources and capabilities to become more competitive and disruptive in their offerings. The phenomenon of interest is described by applying a case study qualitative approach to three 4.0 companies which use virtual reality (VR)/augmented reality (AR)…
Introduction and Psychometric Validation of the Resilience and Strain Questionnaire (ResQ-Care)— A Scale on the Ratio of Informal Caregivers' Resilie…
2021
Background: Informal caregivers are a particularly vulnerable population at risk for adverse health outcomes. Likewise, there are many scales available assessing individual caregiver burden and stress. Recently, resilience in caregivers gained increasing interest and scales started to assess resilience factors as well. Drawing on a homeostatic model, we developed a scale assessing both caregivers' stress and resilience factors. We propose four scales, two covering stress and two covering resilience factors, in addition to a sociodemographic basic scale. Based on the stress:resilience ratio, the individual risk of adverse health outcomes and suggestions for interventions can be derived.Metho…
Smartphone Addiction Inventory (SPAI): Psychometric properties and confirmatory factor analysis
2016
The Smartphone Addiction Inventory (SPAI) was developed to assess smartphone addiction in Taiwanese university students. The purpose of the current research is to evaluate the factor structure and psychometric properties of the SPAI in Italian university students. A total of 485 university students (29.3% boys) completed the SPAI and the Young's Internet Addiction Test (IAT).The proposed four-factor model of the SPAI-I was tested by computing CFA, and the results of the goodness of fit indices indicated an ambiguous solution. An exploratory-confirmatory cross validation strategy was applied for a better trimming of SPAI-I factorial structure. Results suggested a five-factor solution that ex…
