Corporate strategy in the field of sustainability

Objeto: El documento pretende fortalecer las estructuras de análisis identificando los aspectos que dentro de una exploración bibliográfica y bajo el criterio de los académicos sean considerados relevantes para la valoración de logros y evolución de la organización en relación a su estrategia de sostenibilidad. Diseño/metodología/enfoque: Metodología de investigación cualitativa. El estudio parte de una retrospectiva bibliográfica de 25 años, con base en las interpretaciones realizadas por los autores de 90 artículos en el ámbito de la gestión de la sostenibilidad; de esta manera se establece un consenso de opinión respecto a aspectos de marcado interés que debe contener un instrumento de enfoque analítico que permita ajustar la estrategia de sostenibilidad de la organización. Aportaciones y resultados: Los contextos que alcanzaron un mayor consenso y presentan un marcado interés para los autores son los que asocian aspectos relacionados con los elementos de control necesarios para que exista una adecuada comprobación, inspección, fiscalización o intervención en los procesos de gestión de la sostenibilidad, e integración dentro de la estructura operativa de la empresa como un elemento de cohesión entre los mecanismos de gestión corporativa. Limitaciones: Los datos cualitativos son una muestra representativa de artículos en un idioma específico, los cuales fueron extractados de dos bases de datos bibliográficos (Scopus e ISI Web Knowledge). Aunque existe un amplio y variado catálogo de artículos en diferentes idiomas y en diversas bases de datos, es una exploración exhaustiva que está más allá del alcance de este estudio. Implicaciones prácticas: El estudio pone de relieve la importancia de asociar los datos recogidos de los diferentes Mecanismos de Gestión Corporativa (MGC) que están directamente involucrados en la estrategia de sostenibilidad, así como los retos que implica el uso de dichos datos para ampliar los beneficios que esta área aporta a la relación de sustentabilidad local-global. Implicaciones sociales: El estudio propone la implementación del cuadro de mando en las organizaciones, como herramienta de coordinación horizontal para los mecanismos de gestión corporativa; de esta manera se proporciona a los administradores una mirada global de la organización desde diferentes perspectivas; su uso como soporte a la gestión es de alto valor, ya que permite controlar de forma continua si una empresa va a alcanzar los resultados definidos dentro de un plan estratégico de sostenibilidad. Originalidad / Valor añadido: El estudio ofrece una visión de los aspectos de gestión que de forma iterativa siguen siendo base de estudio por académicos, y que mediante una re-asociación de ideas permite la generación de una propuesta con base en algunos consensos identificados.Purpose: The paper aims to strengthen the structures of analysis by identifying relevant aspects that within a bibliographic exploration and under academic criteria are considered relevant to assessment of corporate achievements and evolution in relation to its sustainability strategy. Design/methodology: Qualitative research methodology. The paper is a literature retrospective of 25 years, based on interpretations made by the authors of 90 articles in the field of sustainability management; thus a consensus of opinion is established in relation to aspects of strong interest in order to develop an instrument with analytical approach and strategy. Findings: The contexts that reached greater consensus and have a strong interest for authors are those aspects associated with required elements of "Control" for a proper check, inspection, supervision or intervention in sustainability management processes, and "Integration" within the corporate operational structure as an element of cohesion between corporate management mechanisms. Research limitations/implications: Qualitative data are a representative sample of articles in a single language, which were extracted from two bibliographic databases (Scopus and ISI Web Knowledge). Although there is a wide and varied catalogue of articles in different languages and in different databases, it is an exhaustive exploration that goes beyond the scope of this study. Practical implications: The paper highlights the importance of linking data collected from different corporate management mechanism which are directly involved in the sustainability strategy and challenges of using such data to extend the benefits this association brings to the relationship of local-global sustainability. Social implications: The paper propose the implementation of a scorecard to organizations as horizontal coordination tool for corporate management mechanisms; thus it's provided to managers a global view of the organization from different perspectives; its use as management support has high value, since allowing continuously monitor whether a company will achieve defined outcomes within a strategic sustainability plan. Originality/value: The paper provides an overview of management aspects that remain iteratively as base of research studies by scholars and that through a reassociation of ideas allows the setting up a proposal regarding at some consensus identified.Peer Reviewe

Funding for the Sloan Digital Sky Survey IV has been provided by the Alfred P. Sloan Foundation, the U.S. Department of Energy Office of Science, and the Participating Institutions.We present the MaNGA Dwarf galaxy (MaNDala) Value Added Catalog (VAC), from the final release of the Sloan Digital Sky Survey-IV program. MaNDala consists of 136 randomly selected bright dwarf galaxies with M* −18.5, making it the largest integral field spectroscopy homogeneous sample of dwarf galaxies. We release a photometric analysis of the g, r, and z broadband imaging based on the DESI Legacy Imaging Surveys, as well as a spectroscopic analysis based on the Pipe3D SDSS-IV VAC. Our release includes the surface brightness (SB), geometric parameters, and color profiles, Sérsic fits as well as stellar population properties (such as stellar ages, metallicities, and star formation histories), and emission lines' fluxes within the FOV and the effective radii of the galaxies. We find that the majority of the MaNDala galaxies are star-forming late-type galaxies with 〈nSersic,r〉∼1.6 that are centrals (central/satellite dichotomy). MaNDala covers a large range of SB values (we find 11 candidate ultra-diffuse galaxies and three compact ones), filling the gap between classical dwarfs and low-mass galaxies in the Kormendy Diagram and in the size–mass/luminosity relation, which seems to flatten at 108 2, while the last 20% was at 〈z〉 < 0.3. Finally, a bending of the sSFR-M * relation at M* ∼ 109 M⊙ for the main-sequence galaxies seems to be supported by MaNDala.Publisher PDFPeer reviewe

No evidence of SARS-CoV-2 infection in wild mink (Mustela lutreola and neogale vison) from northern Spain during the first two years of pandemic

The impact of the SARS-CoV-2 pandemic on wildlife is largely unevaluated, and extended surveillance of animal species is needed to reach a consensus on the role of animals in the emergence and maintenance of SARS-CoV-2. This infection has been detected in farmed and domestic animals and wild animals, mainly in captivity. The interactions or shared resources with wildlife could represent a potential transmission pathway for the SARS-CoV-2 spill over to other wild species and could lead to health consequences or the establishment of new reservoirs in susceptible hosts. This study evaluated the presence of SARS-CoV-2 in European mink (Mustela lutreola) and American mink (Neogale vison) in Spain by enzyme-linked immunosorbent assay (ELISA) using the receptor binding domain (RBD) of Spike antigen in serum samples and/or by RT-qPCR assays in oropharyngeal and rectal swabs. From January 2020 to February 2022, a total of 162 animals (127 European mink and 35 American mink) with no evidence of SARS-CoV-2 infection were included in the study. Antibodies against the SARS-CoV-2 were not found in the serum samples analysed (n = 126), nor was the virus amplified by RT-qPCR (n = 160 swabs). Our results suggest that the potential role of wild mink and the European mink bred in captivity and released to the wild as dispersers of SARS-CoV-2 is so far low. However, wildlife surveillance for early detection of human and animal risks should be continued. In this sense, epidemiological monitoring measures, including serology and molecular analysis, are necessary

Constraints on the χ_(c1) versus χ_(c2) polarizations in proton-proton collisions at √s = 8 TeV

The polarizations of promptly produced χ_(c1) and χ_(c2) mesons are studied using data collected by the CMS experiment at the LHC, in proton-proton collisions at √s=8  TeV. The χ_c states are reconstructed via their radiative decays χ_c → J/ψγ, with the photons being measured through conversions to e⁺e⁻, which allows the two states to be well resolved. The polarizations are measured in the helicity frame, through the analysis of the χ_(c2) to χ_(c1) yield ratio as a function of the polar or azimuthal angle of the positive muon emitted in the J/ψ → μ⁺μ⁻ decay, in three bins of J/ψ transverse momentum. While no differences are seen between the two states in terms of azimuthal decay angle distributions, they are observed to have significantly different polar anisotropies. The measurement favors a scenario where at least one of the two states is strongly polarized along the helicity quantization axis, in agreement with nonrelativistic quantum chromodynamics predictions. This is the first measurement of significantly polarized quarkonia produced at high transverse momentum
