La Innovación Colaborativa en la PyME Familiar: Conceptualización, Objetivos y Factores de Éxito

In a constantly changing environment, collaborative innovation enables the knowledge creation and new product designs, the improved efficiency of the production process and the reduction of time-to-market. However, the achievement of such results in the family SME depends mainly on the unique characteristics of this type of organization, which in turn represent the most widespread kind of business worldwide. Therefore, the objective of this article is to analyze how the composition of the management team, and the factors related to the capabilities –cognitive factors, absorptive capacity, and innovative trajectory- and the attitudes –preservation of SEW legacy and intra-organizational behavior- of the decision makers, mediated mainly by the influence of the family, affect when designing and implementing collaborative innovation processes in a successful way.En un entorno en constante cambio, la innovación colaborativa permite la creación de conocimiento y de nuevos diseños, la mejora de la eficiencia del proceso de producción y la reducción de tiempo para la comercialización de los nuevos productos. Sin embargo, la consecución de tales resultados en las pymes familiares depende en buena medida de las características propias de este tipo de organizaciones, que a su vez representan el tipo de empresa más extendida a nivel mundial. Por lo tanto, el objetivo de este artículo es analizar como la composición del equipo directivo, los factores relacionados con la capacidad –factores cognitivos, capacidad absorptiva y trayectoria innovadora- y las actitudes –preservación del legado socio-emocional y comportamiento intra-organizacional- de los decisores, en buena medida influenciados por la familia, afectan al momento de diseñar e implementar los procesos de innovación colaborativa de manera exitosa.&nbsp

Socially Responsible Investing as a Competitive Strategy for Trading Companies in Times of Upheaval Amid COVID-19: Evidence from Spain

Sustainable and responsible investing (SRI) is a strategy that seeks to combine both financial return and social good. The need to create and preserve SRI represents a key argument in investment decision-making, which leads other firms and investors to make strategic decisions beyond financial logic, based on environmental, social, and governance (ESG) factors. Within this framework, this paper aims to further clarify the understanding of potentially profitable strategies for firms during a global crisis such as a pandemic. Both primary and secondary data were gathered, and descriptive analyses were conducted. In Spain, several IBEX-35 companies announced donations amid the COVID-19 crisis. First, companies were classified into two groups based on donations made. For this, we searched for ESG online news. Then, profitability records amongst companies were identified and compared. In the trading session after the announcements, we found 12 of the 35 companies that made donations had a higher performance index of more than 2 and 3 points over the companies that did not make donations. With a weekly perspective, the difference was 91 and 60 basis points, respectively. These results suggest that in times of upheaval, investors base their strategy on ESG factors, contributing to the emerging literature on individual motives of SRI. Second, by conducting a survey and collecting data from 575 Spanish citizens, we conclude that after this crisis, people’s perceptions towards corporate social responsibility (CSR) will change, affecting consumption preferences in those companies that exhibited socially irresponsible or unsupportive behaviour. Hence, the reputation of firms, their social image, and social trust will play an important role in the near future

An Exploratory Data Analysis on the Influence of Role Rotation in a Small-Sided Game on Young Soccer Players

The aim of the present study was to analyze the behavior of players in a standard smallsided game (SSG) according to the role played (offensive (OF), defensive (DF), and wildcard (W)) and its relationship with physical demands (PHYD), technical performance (TP), and internal load (RPE). A total of 24 young highly trained male soccer players (under 16: n = 12; under 19: n = 12) participated. During the SSG, the players alternated the three roles (OF, DF, and W). The duration of each repetition was 4 min with a passive rest of 3 min between them. Furthermore, it emphasized the high demand in all defensive parameters. In addition, DF roles showed higher values in PHYD and RPE, followed by the OF roles, and finally by the W roles. A complementary, positive moderate correlation was found between PHYD and RPE in the U16 dataset (r = 0.45, p < 0.006). Very large positive correlations were also found between PHYD and RPE in the U19 and merged dataset (r = 0.78, p < 0.001 and r = 0.46, p < 0.63, respectively). This information could be useful for coaches in order to structure the roles in SSGs and control training load.Football Connection (FOOC) (Marca No. 4.073.379

Comparative study of the combustion, pyrolysis and gasification processes of Leucaena leucocephala: Kinetics and gases obtained

Leucaena leucocephala is a fast-growing leguminous biomass with great energetical and valueadded chemical compounds potential (saccharides, biogas, bio-oil, etc.). Using the thermogravimetric and derivative thermogravimetric curves, the different trends followed by L. leucocephala during pyrolysis, 0.25 equivalence ratio (ER) of gasification, 0.50 equivalence ratio of gasification and combustion were analyzed, and the activation energies were obtained by Distributed Activation Energy Model (DAEM) method. Gas samples were collected through adsorption tubes during the gasification at 0.25 ER and 0.50 ER to observe the distribution of the main chemical products in this process by gas chromatography/mass spectrometry and were compared with pyrolysis products. It was found that small amounts of oxygen have changes in the kinetics of the process, leading to significant decreases in the activation energy at the beginning of the degradation of components such as cellulose (from 170 to 135 kJ mol-1 at 0.25 conversion at 0.50 ER gasification). The activation energy of lignin disintegration was also reduced (342 kJ mol-1), assimilating the beginnings of gasification processes such as the Boudouard reaction. 0.50 ER gasification is potentially an interesting process to obtain quality bio-oil, since a large amount of hexane is detected (44.96%), and value-added oxygenated intermediates such as alcohols and glycols. Gasification at 0.25 ER, on the other hand, is much more similar to pyrolysis, obtaining a wide variety of short-chain compounds resulting from the disintegration of the main lignocellulosic components, especially ketones such as 1-hydroxypropan-2-one (19.48%), and notable amount of furans and anhydrosugars like d-allose (5.50%).This study was supported by the Ministry of Economy and Competitiveness (Spain), as well as by the National Research Program Oriented to the Challenges of Society (Project PID2020-112875RB-C21 funded by MCIN/AEI 10.13039/501100011033, t)he Ministry of Innovation, Science and Business of the Government of the Junta of Andalusia (Spain), the Operative Program is framed within FEDER Andalusia 2014–2020 with Project number UHU-125540, and the CEPSA Foundation Chair.

Energetic valorization of MSW compost valorization by selecting the maturity conditions.

MSW compost valorization under combustion, at two different composting process conditions, have been studied by thermogravimetric analysis (TGA). The composting operating parameters such as aeration and moisture affect the biodegradability of compost and results of the combustion (different gross heating values for each reactors). The obtained TGA showed that maximum weight loss for 10–12% (245–247 °C), 32–34% (407–411 °C) and 44–46% (760–769 °C) in correspondence to hemicellulose, cellulose and lignin-humic-fulvic acids decomposition for each reactor are observed. Obtained valued in kinetic study (Flynn-Wall-Ozawa method) results in suitable coefficients of determination. In that form, to establish the assumption that combustion of compost under a firstorder reaction may be appropriate. Moreover, in both reactors, the conversion rate increased and the activation energy decreased with composting time is found. The maximum gross heating value versus minimum activation energy (for α = 0.25 and α = 0.5) corresponds to final composts and under aeration of 0.050 and 0.175 Lair kg-1 d-1 and moisture of 40% and 55% for R1 and R2 reactors respectively. For MSW, under proper conditions, composting could be used as a suitable biodrying process, stabilizing and concentrating the heating value.This study received financial support from Ministry of Economy and Competitiveness.

Kinetic synergistic effect in co-pyrolysis of Eucalyptus globulus with high and low density polyethylene

The pyrolysis of Eucalyptus globulus (EG) with different blends of high density polyethylene (HDPE) and low density polyethylene (LDPE) by thermogravimetry has been studied. ASTM-E1641-16 standard method has been used to evaluate the kinetics during the pyrolysis of the studied blends. For all feedstocks (EG, HDPE and LDPE) and blends studied, the relative content (%) of the volatile organic compound has been determined by GC–MS analysis. Different synergistic effects on the activation energy of EG blends with HDPE and LDPE have been found. EG-HDPE blends showed a minimum activation energy (Ea) (125 kJ mol−1) at the 80% EG–20% HDPE ratio, while the minimum Ea value for EG-LDPE blends was found at the 60% EG–40% LDPE ratio (135 kJ mol−1) has been identified. To test which components exert a greater synergistic effect, mixtures of HDPE and LDPE with the main components of eucalyptus (cellulose, hemicellulose and lignin) have also been studied. However, no synergistic effects on the pyrolysis of cellulose have been detected. Moreover, in hemicellulose and lignin with both types of polyethylene mixtures, a significant decrease in Ea has been appreciated. The lowest Ea values for 60% cellulose–40% HDPE (167 kJ mol−1) and 60% lignin–40% HDPE (140 kJ mol−1) has been calculated. On the other hand, minimum values for 40% cellulose–60% LDPE (166 kJ mol−1) mixture and for 40% lignin–60% LDPE (168 kJ mol−1) mixture have been detected. Thus, the decrease in both Ea and the Arrhenius pre-exponential factor on the eucalyptus-polyethylene blends to the presence of hemicellulose and lignin can be attributed. Moreover, during the co-pyrolysis of HDPE-EG mixtures, n-paraffins, ketones, phenols and sugars are the main VOCs identified. In contrast, in LDPE-EG mixtures, only n-paraffins (55%) and olefins (44%) have been identified.This study received financial support from Green Asphalt project (ref. 802C1800001) co-funded 80% by FEDER European Programme and 20% by the Regional Government of Andalusia (Agency for Innovation and Development of Andalusia (IDEA) and (Operational Programme FEDER Andalusia 2014–2020, Project UHU–1255540), Spain.

Análisis de Productividad en la Industria Manufacturera en México Antes y Durante la Pandemia del Covid-19

Labor productivity measures the relationship between the amount of work invested in the production process and the output produced. The hypothesis that was proposed was that productivity in the manufacturing industry (Nemur, 2016) in Mexico has been declining. Therefore, it is expected to find significant evidence that the industry has had low rates. The most common methods to measure productivity are: based on production volume, employed personnel and hours worked. Therefore, the main contribution of this work was to show through qualitative and statistical analysis that the manufacturing industry in Mexico has maintained a very inconsistent level of productivity of ups and downs. The main results obtained were that productivity in relation to production volume was obtained at .047, which is significant, since it was less than .05, and the average without pandemic and with pandemic was 10.2, the difference without pandemic was greater the level of productivity.La productividad laboral mide la relación entre la cantidad de trabajo invertido en el proceso de producción y la producción producida.

Los métodos más comunes para medir la productividad son: en base al volumen de producción, al personal ocupado y las horas trabajadas. Por lo tanto, el principal aporte de este trabajo fue mostrar a través de análisis cualitiativo y estadístico que la industria manufacturera en México ha mantenido un nivel de productividad de altibajos, muy inconsistente. Los principales resultados obtenidos fueron que la productividad en relación al volumen de producción se obtuvo un .047 el cual es significativo, ya que fue menor a .05, y la media sin pandemia y con pandemia fue de 10.2, la diferencia sin pandemia fue mayor el nivel de productividad

Ultrasound extraction optimization for bioactive molecules from Eucalyptus globulus leaves through antioxidant activity

Antioxidant products present a very high added value and are demanded in the market. The optimization of their extraction is a high-stakes matter for both economic and environmental points of view. Ultrasound extraction has been considered one of the most promising methods, so the relative importance of key parameters may have decisive economic significance. For this reason, different parameters that have influence on the extraction capacity such as ultrasound power, time, temperature, pH and % ethanol in water have been studied to know the relationships between the independent parameters and their influence on the extraction from Eucalyptus globulus leaves. An experimental Box-Behnken factorial design and subsequent analysis by neural networks have been used. The relative influence of each parameter varies according to the nature of the extracted compound. In this regard, the higher capacity of extraction of the selected antioxidant compounds by means of the variation of the operation conditions can be facilitated. For all the studied compounds, temperature has been the most important parameter for their extraction. The relative content (%) of bioactive compounds (terpenes) in the optimized Eucalyptus globulus extract has been performed by GC–MS analysis

Optimization of bioactive compounds by ultrasound extraction and gas chromatography - mass spectrometry in fast-growing leaves

Fast-growing crops are of great economic importance in the production of paper pulp and energy. The commercialization of the bioactive components from underutilized parts could provide additional value to these crops. In the present study, chromatography gas coupled to mass spectrometry triple quadrupole (GC–MS/MS) and ultrasound extraction technique was used in the bioactive compounds determination in fast-growing crops leaves. Twenty-one terpenes and eight polyphenolic bioactive compounds were studied. Prior to GC–MS/MS, polydimethylsiloxane (PDMS) - stir bars preconcentration and trimethylsilane (TMS) derivatization steps were used for terpenes and polyphenolic compounds, respectively. Several parameters (pH, temperature, ethanol–water mixtures, ultrasound power, and ultrasound time) of the extraction step were optimized by central composite experimental design. Ethanol content, ultrasound power, and ultrasound time were the parameters that most influence the extraction efficiency of terpenes in biomass residues, while for polyphenolic compounds it was temperature and ultrasound time. The optimal ultrasound extraction conditions for terpenes were 60% ethanol, pH 4, 80 W, 40 ºC, and 15 min, whereas for polyphenolic compounds they were 60% ethanol, pH 4, 120 W, 50 ºC, and 15 min. The detection limits (LOD) were in the range of 0.200–3.02 µg kg−1 and 7.9–540 µg kg−1 for terpenes and polyphenolic compounds, respectively. The developed analytical method was applied to twelve fast-growing leaves (Leucaene (diversifolia and leucocephala), Eucalyptus (globulus and urograndis), Populus (I214 and AF2), Prosopis (alba and juliflora), Robinia, Tagasaste, Ulmus pumila, and Paulownia). Eucalyptol was the mayor terpene present in all the plants studied, while chlorogenic and quinic acid were the mayor phenolic compounds.This study was supported by the Ministry of Economy and Competitiveness (Spain), as well as by the National Research Program Oriented to the Challenges of Society (Project PID2020-112875RB-C21 funded by MCIN/AEI /10.13039/501100011033), and the Ministry of Innovation, Science and Business of the Government of the Junta of Andalusia (Spain), the Operative Program is framed within FEDER Andalusia 2014–2020 (Project UHU-125540).

Psychometric Characteristics of a Commuting-to-School Behaviour Questionnaire for Families

The purposes of this study were: (a) to describe the patterns of modes of commuting to school (children) and to work (parents) separated by gender and age, (b) to validate the questions on children’s mode of commuting to and from school according to their parents, and (c) to analyse the reliability of a family questionnaire focused on commuting to school behaviours. A total of 611 parents (mean age: 43.28 6.25 years old) from Granada (Spain) completed “Family commuting-to-school behaviour” questionnaire in two sessions separated by 14 days, (2016 and 2018). The validation between family and children’s questions was assessed using the Kappa and Spearman correlation coe cients, and the test–retest reliability within the family questions was assessed using the Kappa and the weighted Kappa. The children’s modes of commuting to school (mean age: 11.44 2.77 years old) were mainly passive (57.7% to school) while parents’ modes of commuting to work were mainly active (71.6%). The validity of the mode of commuting was significant with high Kappa and Spearman coe cients. The test–retest reliability presented a good agreement for the mode of commuting to school in children, distance and time to school, and the mode of commuting to work in parents, while the questions on acceptable distance to walk or cycle to school showed a moderate to good agreement. The “Family commuting-to-school behaviour” questionnaire could be a useful tool to assess the mode of commuting of children, distance and time to school for researchers and practitioners.Spanish Ministry of Economy, Industry and CompetitivenessEuropean Regional Development Fund (MINECO/FEDER, UE) DEP2016-75598-RUniversity of Granada, Plan Propio de Investigacion 2016, Excellence actions: Units of Excellence; Unit of Excellence on Exercise and Health (UCEES)Junta de AndalucíaEuropean Union (EU) SOMM17/6107/UGRJunta de AndalucíaEuropean Social Fund (ESF
