    In this paper, after some clarifications about the definition and characteristics of Family Business (FB), a literature review on innovation and cooperation in FB has been conducted. As a consequence, a research gap regarding how FB develops innovation when cooperating with external factors has been identified. In particular, specific characteristics of FB have been analysed regarding innovation and cooperation, such as longer-term vision, risk aversion, and relatively lack of professionalism of FB workers.En este artículo, después de exponer algunas aclaraciones sobre la definición y las características de las Empresas Familiares (FB), se realiza una revisión de literatura sobre innovación y cooperación en las FBs. Como consecuencia de esta revisión, se ha detectado un gap de investigación sobre cómo las FBs desarrollan la innovación cuando se realiza en cooperación con factores externos. Se han analizado, de forma específica, algunas características de FBs con respecto a la innovación y la cooperación, en concreto, la visión más a largo plazo, la aversión al riesgo y la falta de profesionalización de los trabajadores de las FB.&nbsp

    Tras el proceso de M&A descrito en el párrafo anterior entre los proveedores de infraestructura, suscita el interrogante en torno a cuáles fueron los efectos que impactaron el Mercado de Capitales brasileño a partir del año 2001. Por consiguiente, el objeto del documento es analizar los efectos que tuvo el proceso de M&A entre los 7 proveedores de infraestructura en Brasil, en términos de liquidez, volatilidad, volumen transaccional y cantidad de negocios, al ser éstas variables representativas que dan un panorama generalizado del mercado. Para ello, se consideró necesario examinar en el marco internacional mercados que hayan experimentado procesos de integración que sirvan de referente para el mercado brasileño. Posteriormente, desarrollar un modelo econométrico que permita analizar los efectos en las variables liquidez, volatilidad, volumen transaccional y cantidad de negocios para el periodo antes y después de la M&A. Por último, analizar los resultados obtenidos en el modelo econométrico, para determinar el impacto de la integración en el mercado de capitales brasileño.M&A para Proveedores de Infraestructura en el Contexto Internacional.

    Con este trabajo se pretende comprobar si las afirmaciones realizadas en la literatura sobre las características de la aversión al riesgo, la visión de largo plazo o la profesionalización de los trabajadores de las empresas familiares (EFs) suponen un perfil adecuado para que este tipo de empresas desarrollen la innovación de la mano de un agente externo. Dada la importancia hoy día del sector turístico, y el efecto que ha tenido en él la última crisis del COVID-19, se ha centrado el estudio en las empresas familiares de hostelería. Desde la perspectiva de las EFs, el resultado de la investigación les ayudará a diagnosticar variables del entorno favorable y desfavorable y, en consecuencia, tendrán una herramienta para moderar, en parte, la incertidumbre de un proceso de innovación para este tipo de empresas. Por tanto, les servirá para innovar con más garantías y garantizar su supervivencia generación tras generación. Es importante profundizar en el estudio de por qué algunas empresas familiares logran innovar abiertamente mientras que otras fracasan y también se hace énfasis en realizar estudios de casos más amplios para profundizar en la explicación de la heterogeneidad de las empresas familiares basadas en atributos distintos a aquellos en los que nos enfocamos (gestión familiar, estructura de gobierno, generación).Universidad de Málaga.

    Valorization of Municipal Biowaste into Electrospun Poly(3-hydroxybutyrate-co-3-hydroxyvalerate) Biopapers for Food Packaging Applications

    American Chemical Society[EN] The present study reports on the production and characterization of a new biopackaging material made of poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) derived from municipal biowaste (MBW) and produced by the mixed bacterial culture technology. After purification and extraction, the MBW-derived PHBV was processed by electrospinning to yield defect-free ultrathin fibers, which were thermally post-treated. Annealing at 130 degrees C, well below the biopolymer's melting temperature (T-m), successfully yielded a continuous film resulting from coalescence of the electrospun fibrillar morphology, the so-called biopaper, exhibiting enhanced optical and color properties compared to traditional melt compounding routes. The crystallinity and crystalline morphology were comprehensively studied as a function of temperature by attenuated total reflectance-Fourier transform infrared (ATR-FTIR) spectroscopy and combined time-resolved synchrotron small- and wide-angle X-ray scattering (SAXS and WAXS) experiments, which clearly indicated that the molecular order within the copolyester was improved up to a maximum at 130 degrees C, and then it decreased at the biopolymer's T-m. It was hypothesized that by annealing at the temperature at which the thermally induced molecular order is maximized, the fibers generated sufficient mobility to align alongside, hence reducing surface energy and porosity. The data suggest that this material shows a good balance between enhanced mechanical and improved barrier properties to vapors and gases in comparison to traditional paper and other currently used petroleum-derived polymers, thus presenting significant potential to be part of innovative food biopackaging designs for the protection and preservation of foods in a circular bioeconomy scenario.The Spanish Ministry of Science and Innovation (MICI) project RTI2018-097249-B-C21 and EU projects H2020 YPACK (reference number 773872) and H2020 USABLE (reference number 836884) are acknowledged for funding support.

    Development and Characterization of Electrospun Biopapers of Poly(3-hydroxybutyrate-co-3-hydroxyvalerate) Derived from Cheese Whey with Varying 3-Hydroxyvalerate Contents

    [EN] In the present study, three different newly developed copolymers of poly(3-hydroxybutyrate-co-3-hydroxyval-erate) (PHBV) with 20, 40, and 60 mol % contents in 3-hydroxyvalerate (3HV) were produced by the biotechnological process of mixed microbial cultures (MMCs) using cheese whey (CW), a by-product from the dairy industry, as feedstock. The CW-derived PHBV copolyesters were first purified and then processed by solution electrospinning, yielding fibers of approximately 2 mu m in cross-section in all cases. The resultant electrospun PHBV mats were, thereafter, post-processed by annealing at different temperatures, below their maximum of melting, selected according to their 3HV content in order to obtain continuous films based on coalesced fibers, so-called biopapers. The resultant PHBV films were characterized in terms of their morphology, crystallinity, and mechanical and barrier properties to assess their potential application in food packaging. The CW-derived PHBV biopapers showed high contact transparency but a slightly yellow color. The fibers of the 20 mol % 3HV copolymer were seen to contain mostly poly(3-hydroxybutyrate) (PHB) crystals, the fibers of the 40 mol % 3HV copolymer a mixture of PHB and poly(3-hydroxyvalerate) (PHV) crystals and lowest crystallinity, and the fibers of the 60 mol % 3HV sample were mostly made of PHV crystals. To understand the interfiber coalesce process undergone by the materials during annealing, the crystalline morphology was also assessed by variable-temperature both combined small-angle and wide-angle X-ray scattering synchrotron and Fourier transform infrared experiments. From these experiments and, different from previously reported biopapers with lower 3HV contents, all samples were inferred to have a surface energy reduction mechanism for interfiber coalescence during annealing, which is thought to be activated by a temperature-induced decrease in molecular order. Due to their reduced crystallinity and molecular order, the CW-derived PHBV biopapers, especially the 40 mol % 3HV sample, were found to be more ductile and tougher. In terms of barrier properties, the three copolymers performed similarly to water and limonene, but to oxygen, the 40 mol % sample showed the highest relative permeability. Overall, the materials developed, which are compatible with the Circular Bioeconomy organic recycling strategy, can have an excellent potential as barrier interlayers or coatings of application interest in food packaging.This research work was funded by the H2020 EU project YPACK (reference number 773872) and by the Spanish Ministry of Science and Innovation (MICI) project RTI2018-097249-B-C21.

    Organocatalyzed closed-loop chemical recycling of thermo-compressed films of poly(ethylene furanoate)

    [EN] Monomers obtained from renewable feedstocks have emerged as a sustainable alternative to petroleum derived polymers. One of the biomass derived polyesters that has recently been gaining attention as an alternative to petrochemical polyethylene terephtalate (PET) for food and beverage packaging applications is poly(ethylene furanoate) (PEF). However, similar to PET, PEF is not biodegradable or compostable and its end-of-life options must be thus considered to avoid contributing to the accumulation of plastic waste. In this manuscript, PEF films were first produced using thermo-compression, an industrially relevant processing method, and their thermal, mechanical, and barrier properties were determined and compared to those of PET and other biopolyesters to ascertain their suitability for food packaging. Thereafter, the chemical glycolysis of PEF film waste was investigated using a sustainable and thermally stable acid-base organocatalyst. After succesfully deconstructing PEF into bis(2-hydroxyethyl)-furan-2,5-dicarboxylate (BHEF), the obtained BHEF diester was used to resynthesize PEF using the same catalyst to generate a new biopolyester with similar thermal properties to the virgin one in a closed-loop cycle.The authors thank for technical and human support provided by IZO-SGI SGIker of UPV/EHU and European funding (ERDF and ESF).
