Three-stage publishing to support evidence-based management practice
[EN] A Spanish version of the article is provided (see section before annex).This article proposes a 4-step model for scientific dissemination that aims to promote evidence-based professional practice in Operations Management or Human Resource Management as well as research with a more transparent and reproducible process. These 4 steps include:1 social network announcements,2 dissemination to scientific journals, 3 dissemination to social networks, and 4 scientific dissemination to professional journals. Central to the 4-step model is a three-stage publication process within the second step, which adds an additional stage to the two previously proposed (Marin-Garcia, 2015). These three publication stages begin with a protocol paper, are followed by a data paper, and finish with a traditional article. Each stage promotes research with merit which is citable and recognizable as such before the scientific evaluation bodies. As two of these stages are largely unknown within the fields of Business and Management, I define the details of a protocol paper and a data paper including their contents. In addition, I provide examples of both papers as well as the other steps of the science dissemination model. This model can be adopted by researchers as a means of achieving greater impact and transfer of research results. This work intends to help researchers to understand, to evaluate, and to make better decisions about how their research reaches society at large outside of academia.In this way, WPOM aligns with the recommendations of several leading journals in the field of business management on the need to promote transparent, accessible, and replicable science (Beugelsdijk et al., 2020). WPOM goes one step further in compliance with this direction by having relevant journals that not only accept, but also actively encourage the publication of protocol papers and data papers. WPOM strives to pioneer in this field of Business and Management.This article also explores the potential prevalence of protocol papers and data papers within the set of all articles published in journals indexed in Clarivate Web of Science and Scopus.With this editorial, WPOM is committed to promoting this model by accepting for review any of the three types of scientific contributions including protocol papers, data papers, and traditional papers.Marin-Garcia, JA.

Galaxy evolution across the optical emission-line diagnostic diagrams?
The discovery of the M-sigma relation, the local galaxy bimodality, and the
link between black-hole and host-galaxy properties, have raised the question
whether AGN play a role in galaxy evolution. Several theoretical models
implement AGN feedback to explain the observed galaxy luminosity function, and
possibly the color and morphological transformation of spiral galaxies into
passive ellipticals. To understand the importance of AGN feedback, a study of
the AGN populations in the radio-optical domain is crucial. A mass sequence
linking star-forming galaxies and AGN has been already noted in previous works,
and it is now investigated as possible evolutionary sequence. We observed a
sample of 119 intermediate-redshift (0.04<z<0.4) SDSS-FIRST radio emitters with
the Effelsberg 100-m telescope at 4.85 and 10.45 GHz and obtained spectral
indices. We find indications of spectral index flattening in high-metallicity
star-forming galaxies, composite galaxies, and Seyferts. This "flattening
sequence" along the [NII]-based emission-line diagnostic diagram is consistent
with the hardening of galaxy ionizing field, due to nuclear activity. After
combining our data with FIRST measurements at 1.4 GHz, we find that the
three-point radio spectra of Seyferts and LINERs show substantial differences,
attributable to small radio core components and larger (arcsecond sized)
jet/lobe components, respectively. A visual inspection of FIRST images seems to
confirm this hypothesis. Galaxies along this sequence are hypothesized to be
transitioning from the active star-forming galaxies (blue cloud) to the passive
elliptical galaxies (red sequence). This supports the suggestion that AGN play
a role in shutting down star-formation, and allow the transition from one
galaxy class to the other.Comment: 20 pages, 19 figures, accepted for publication in A&
Self-sustained spatiotemporal oscillations induced by membrane-bulk coupling
We propose a novel mechanism leading to spatiotemporal oscillations in
extended systems that does not rely on local bulk instabilities. Instead,
oscillations arise from the interaction of two subsystems of different spatial
dimensionality. Specifically, we show that coupling a passive diffusive bulk of
dimension d with an excitable membrane of dimension d-1 produces a
self-sustained oscillatory behavior. An analytical explanation of the
phenomenon is provided for d=1. Moreover, in-phase and anti-phase
synchronization of oscillations are found numerically in one and two
dimensions. This novel dynamic instability could be used by biological systems
such as cells, where the dynamics on the cellular membrane is necessarily
different from that of the cytoplasmic bulk.Comment: Accepted for publication in Physical Review Letter
Estudio exploratorio de los programas de alta implicación de los operarios: identificación de las dimensiones y propuesta de un cuestionario para medir el grado de uso en las empresas
Actualmente, el debate sobre qué prácticas de recursos humanos se incluyen como prácticas de alta implicación de los operarios (High Involvement Work Practices)
debería considerarse todavía abierto. En esta comunicación pretendemos hacer una
revisión del marco teórico que nos permita identificar un conjunto de prácticas de
alta implicación aceptado mayoritariamente y validar una propuesta de cuestionario que mida el grado de uso de las prácticas de alta implicación. La revisión teórica realizada nos ha permitido encontrar un conjunto de 27 prácticas relacionadas con la participación, comunicación, formación y compensación de los operarios y gestión del conocimiento. El análisis exploratorio de los datos nos permite presentar una agrupación alternativa de ítems en 7 escalas en lugar de las 5 que tradicionalmente se venían usando.At the moment, the debate about what human resources practices include as High Involvement Work Practices would have to be considered still open. In this communication we try to make a revision of the theoretical framework. This allows us to identify a set of practices mainly accepted as high involvement. We also validate a questionnaire proposal that measures the degree of use of these practices. The result of the theoretical revision has allowed us to find a set of 27 practices related to the participation, communication, training, compensation and management of the knowledge. The exploratory analysis of the data presents an alternative grouping of items in 7 scales instead of the traditional 5 ones.Peer Reviewe
Verification of the reflective model of first order factors for reward and empowerment constructs based on questionnaires derived from Lawler et al. (1991)
Purpose: High involvement practices have traditionally been classified in four main categories: training, communication, rewards and empowerment. In order to measure the degree of implementation of these programs, different questionnaires have been developed. In this paper, we have identified 3 types of questionnaires and we have deeply analyzed the psychometrical properties of one of these types: questionnaires derived from Lawler et al. (1991). The most recent investigation seems to show that psychometrical properties of both training and communication constructs are appropriate. However, it is necessary to work on rewards and empowerment scales. This research analyzes, by means of confirmatory factorial, two reflective measurement models, already present in the previous literature of rewards and empowerment scales.
Design/methodology/approach: Spanish samples from 1997 (n=105), as well as United States ones (n=212 dating 1996 and n=143 dating 1999) have been used. Convergent and discriminant validity were tested.
Findings and Originality/value: None of the models presents and acceptable adjustment in the used samples. Therefore, a possible future line of investigation in order to check whether the measurement model of rewards and empowerment constructs is formative instead of reflective, has been opened.
Practical implications: Practitioners can profit from the results of this research because questionnaires validity will allow companies to have measurement and good practices diagnosis tools that can be used either for internal benchmarking or for the comparison with reference groups of companies.
Originality/value: Our paper identifies three questionnaire typologies used in the field of investigations of rewards and empowerment practices. We show that the point of view with which the scales of theses questionnaires have been treated has always been reflective. Moreover, this is one of the few papers that have checked the validity of the measurement model of questionnaires derived from Lawler et al. (1991). It questions the validity of a single questionnaire with similar samples, of different years, and simultaneously, with samples from same years but from different countries.Peer Reviewe
Desarrollo y validación de un modelo multidimensional de la producción ajustada
In the last 30 years of research of lean manufacturing many different questionnaires was proposed to check the degree of the use of the concept. The set of the items used changed considerably from one investigation to another one. Until now isn’t appreciate a movement that converge towards the use, by the investigators, of a few instruments whose validity and reliability have been compared in different surroundings. In fact, the majority of investigations are based on ad-hoc questionnaires and a few of them present the questionnaire validation checking only the unidimensionality and -Cronbach. Nevertheless it seems to have a consensus in identifying 5 big constructs that compose the lean manufacturing (TQM, JIT, TPM, supply chain management and high-involvement). Our research has consisted of identifying and summarizing the models that have been published previously to add the items in constructs or sub-scales of constructs. Later we developed an integrating questionnaire, starting off of the items that appeared in previous investigations. Finally we realized the sub-scales and models validation through a confirmatory factorial analysis, using date of a sample of Spanish Sheltered Work Centre’s (N=128). Of all proposed models, the best an adjustment takes place with the first order model with 20 sub-scales. Our investigation contributes to an integrating vision of the published models and the lean manufacturing sub-scales validity and reliability verification raised by other investigators. Due to his confirming approach, it can serve as generalization of studies that had been realized in contexts with different samples to which we have used for the replication.En los últimos 30 años de investigación sobre producción ajustada se han
propuesto deferentes cuestionarios para diagnosticar el grado de uso de este
concepto. El conjunto de ítems empleado ha variado notablemente de una
investigación a otra. No se aprecia todavía un movimiento que converja hacia la
utilización, por parte de los investigadores, de unos pocos instrumentos cuya
validez y fiabilidad se haya contrastado en diferentes entornos. De hecho, la
mayoría de las investigaciones se basan en cuestionarios ad-hoc y pocas de ellas
presentan una validación del cuestionario más allá de verificar la
unidimensionalidad y el de Cronbach. Sin embargo, parece haber consenso en
identificar 5 grandes constructos que componen la producción ajustada (gestión de
la calidad, flujo interno de producción, mantenimiento, gestión de la cadena de
suministro y la implicación de los operarios). Nuestro trabajo ha consistido en
identificar y resumir los modelos de producción ajustada, identificando el modo en
que agregan los ítems en constructos o sub-escalas de constructos. Posteriormente
hemos desarrollado un cuestionario partiendo de los ítems que figuraban en los
modelos publicados. Finalmente, hemos realizado la validación de sub-escalas y
modelos mediante un análisis factorial confirmatorio, usando datos de una muestra
de Centros Especiales de Empleo españoles (N=128). De todos los modelosplanteados, el mejor ajuste se produce con el modelo de 20 sub-escalas de primer
orden. Nuestro trabajo aporta una visión integradora comparando los modelos publicados previamente y la comprobando la validez y fiabilidad de las sub-escalas
de producción ajustada planteadas por otros investigadores. Debido a su enfoque
confirmatorio, puede servir de generalización de estudios que se habían realizado en contextos con muestras diferentes a las que nosotros hemos empleado para la replicación.Peer Reviewe
Strategic Priorities and Lean Manufacturing Practices in Automotive Suppliers. Ten Years After
What do we know about rubrics used in higher education?
Castellano: Objeto: En este artículo comparamos las estrategias de búsqueda y los resultados de
tres revisiones de literatura recientes sobre uso rúbricas en educación. Con todo ello
pretendemos identificar qué se sabe, que no se sabe aún y si hay material para lanzar
una nueva revisión de literatura en estos momentos.
Diseño/metodología/enfoque: Análisis comparado de las tres revisiones de
literatura reciente y búsqueda sistemática de literatura.
Aportaciones y resultados: De los 142 artículos incluidos en las tres revisiones
recientes, pocos se centran en docencia universitaria y los resultados no se presentan
desagregados por niveles educativos. Consideramos que no existe una respuesta
científica concluyente para cómo crear y validar una rúbrica para evaluación de
asignaturas universitarias, ni para qué sirven las rúbricas, ni si vale la pena el esfuerzo
de desarrollarlas. Las recomendaciones para el uso adecuado de rúbricas están basadas
en evidencias anecdóticas sin una metodología robusta y contrastada. Tampoco es fácil
localizar qué asignaturas, ni qué objetos, ni en qué contextos han sido objeto de
investigación las rúbricas, ni qué rúbricas validadas hay disponibles para ellos.
Originalidad / Valor añadido: Hemos realizado una nueva revisión y comparamos los
artículos seleccionados con los utilizados en las revisiones anteriores. Hemos localizado 241 nuevos artículos no incluidos en las revisiones anteriores. Probablemente con todo
este nuevo material se pueda realizar en el futuro algún meta-análisis.English: Purpose: In this paper we compare the search strategies and the results of three
recent literature reviews on the rubrics use in education. With all this we aim to identify
what is known, what it is not known yet and if there is material to launch a new
literature review right now.
Design/methodology: Comparative analysis of three recen literature reviews and
systematic literature review.
Findings: Of the 142 papers included in the three recent reviews, few focus on
university learning and the results are not broken down by educational level. We believe
that there is no conclusive scientific answer to how to create and validate an
assessment rubric for university courses, or what purpose they serve , or if it's worth
the effort to develop them. Recommendations for the appropriate use of rubrics are
based on anecdotal evidence without robust and proven methodology. Nor is easy to
find what subjects, or what objects, and in what contexts have been investigated the
rubrics or which validated rubrics are available.
Originality/value: We conducted a new review and we compare the selected papers
with those used in previous reviews. We have located 142 new papers not included in
previous reviews. Probably all this new material can be used in the future for a metaanalysis.Peer Reviewe
A low-luminosity type-1 QSO sample; III. Optical spectroscopic properties and activity classification
We report on the optical spectroscopic analysis of a sample of 99
low-luminosity quasi-stellar objects (LLQSOs) at base the
Hamburg/ESO QSO survey (HES). The LLQSOs presented here offer the possibility
of studying the faint end of the QSO population at smaller cosmological
distances and, therefore, in greater detail. A small number of our LLQSO
present no broad component. Two sources show double broad components, whereas
six comply with the classic NLS1 requirements. As expected in NLR of broad line
AGNs, the [S{\sc{ii}}]based electron density values range between 100 and
1000 N/cm. Using the optical characteristics of Populations A and
B, we find that 50\% of our sources with H broad emission are consistent
with the radio-quiet sources definition. The remaining sources could be
interpreted as low-luminosity radio-loud quasar. The BPT-based classification
renders an AGN/Seyfert activity between 50 to 60\%. For the remaining sources,
the possible star burst contribution might control the LINER and HII
classification. Finally, we discuss the aperture effect as responsible for the
differences found between data sets, although variability in the BLR could play
a significant role as well.Comment: 22 pages; 5 tables; 17 figures; in press with A&
