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.

Gauge invariant MSSM inflaton

We argue that all the necessary ingredients for successful inflation are present in the flat directions of the Minimally Supersymmetric Standard Model. We show that out of many gauge invariant combinations of squarks, sleptons and Higgses, there are two directions, ${\bf LLe}$, and ${\bf udd}$, which are promising candidates for the inflaton. The model predicts more than $10^3$ e-foldings with an inflationary scale of $H_{\rm inf}\sim {\cal O}(1-10)$ GeV, provides a tilted spectrum with an amplitude of $\delta_H\sim 10^{-5}$ and a negligible tensor perturbation. The temperature of the thermalized plasma could be as low as $T_{rh}\sim {\cal O}(1-10)$~TeV. Parts of the inflaton potential can be determined independently of cosmology by future particle physics experiments.Comment: 4 revtex pages, some references added, stabilization of moduli and supergravity effects are discusse

Inferencia del origen del bovino Criollo Cubano a través del análisis de patri- y matrilinajes

Antes de descubrimiento, no existían bovinos en América. Los primeros, fueron introducidos en la Antillas Mayores (La Española, Puerto Rico, Jamaica y Cuba), y desde allí trasladados al resto de Latinoamérica. Actualmente, existen en Cuba alrededor de 1300 bovinos Criollos, concentrados principalmente en la región oriental. Con el objetivo de analizar el origen materno de esta raza y detectar eventos contemporáneos de flujo génico por vía paterna, se analizó un fragmento de 240 pb del D-loop mitocondrial (mtADN) y 5 microsatélites del cromosoma Y (BTY), en 36 hembras y 21 machos respectivamente. La diversidad genética se estimó mediante el número de haplotipos, el número de sitios polimórficos, el número de diferencias nucleotídicas entre pares de secuencias y el índice de diversidad nucleotídica, mientras que el análisis filogenético se realizó utilizando el método de median joining network. Dicho análisis permitió detectar 15 haplotipos mitocondriales (10 del haplogrupo europeo T3, 3 del africano T1, 1 del cercano oriente T2 y 1 ambiguo T1-T3) y 3 haplotipos en el BTY, ambos del haplogrupo cebuíno Y3. En el mtADN se detectaron 23 sitios polimórficos con una diversidad nucleotídica de 0,014 y 3,36 diferencias medias entre pares de secuencias. En conclusión, la población de bovinos Criollos Cubanos presentó una composición haplotípica mitocondrial comparable a la de otras razas criollas y mediterráneas, hecho que concuerda con su origen histórico. El BTY evidenció altos niveles de introgresion paterna de genes del zebú.Cattle was absent from America before the discovery. Initially, bovine were brought to Greater Antilles (La Española, Puerto Rico, Jamaica and Cuba islands), and in the course of a few years, they were taken from Caribbean islands to the rest of Latin America. Nowadays, Cuban Creole cattle population is about 1300 heads, mainly located in the eastern region of the island. With the aim of analyzing the maternal origin of Cuban Creole cattle and detect possible contemporaneous, male mediated, gene flow, a 240 pb fragment of mitochondrial D-loop (mtDNA) and five microsatellites of Y chromosome (BTY) were studied in 36 dams and 21 sires, respectively. Genetic diversity was evaluated through number of haplotypes, mean number of pairwise differences and nucleotide diversity. The phylogenetic analysis was performed using a median joining. A total of 15 mtDNA haplotypes were detected in the studied population (10 from the European haplogroup T3, 3 from the African T1, 1 from the Nearern East T2, and 1 ambiguous T1-T3). The number of polymorphic sites, the mean nucleotide diversity, and the mean number of pairwise differences were 23, 0.014 and 3.36, respectively. Two patrilinages were detected, both belonging to the Y3 Zebu haplogroup. In conclusion, Cuban Creole cattle population had a mtDNA haplotypic composition similar to the observed in Creole and Mediterranean breeds, what is in concordance with its historical origin. Y chromosome analysis evidenced a male mediated process of zebu introgression.Fil: Liron, Juan Pedro. Consejo Nacional de Investigaciones Científicas y Técnicas.

On the viability of a CSO architecture for on-demand virtualized cloud planning and provisioning

As bandwidth requirements and computing capacity for future applications have been predicted to exceed current network and IT infrastructure capabilities, providers face the need to adapt their provisioning models. This article presents the benefits of Cross Stratum Optimized architectures (provision of network and IT resources in a coordinated way) in support of Cloud-based applications. We also present the architecture's potential impact and benefits for operators, based on MACTOR methodology. MACTOR results show the interactions among value-chain actors and identify their business convergences and divergences, revealing the architecture feasibility

Periodic orbits of a perturbed 3-dimensional isotropic oscillator with axial symmetry

We study the periodic orbits of a generalized Yang-Mills Hamiltonian H depending on a parameter β. Playing with the parameter β we are considering extensions of the Contopoulos and of the Yang-Mills Hamiltonians in a 3-dimensional space. This Hamiltonian consists of a 3-dimensional isotropic harmonic oscillator plus a homogeneous potential of fourth degree having an axial symmetry, which implies that the third component N of the angular momentum is constant. We prove that in each invariant space H = h > 0 the Hamiltonian system has at least four periodic solutions if either β 6 and β != 5 sqrt(13). We also study the linear stability or instability of these periodic solutions
