Enhancing organizational performance with social media use: the catalysing effect of corporate entrepreneurship
Social Media use has become pervasive and firms are increasingly relying on it, not only to relate to customers, but also to leverage internal processes like innovation. The strategic use of these tools can facilitate also the entrepreneurial orientation of the firm, as it provides useful knowledge which can make the firm more entrepreneurial, stimulating it to find new opportunities or innovative ideas where other companies do not recognize them. However, despite the relevance of the phenomenon in current hyper-competitive environments, empirical research on the topic remains scarce. To shed some light on the issue, the main purpose of the paper is to examine how Social Media use impacts the different dimensions of corporate entrepreneurship (new business venturing, innovativeness, proactiveness and self-renewal), enhancing also organizational performance. The study is intended to extend knowledge on this topic, by providing understanding of the path firms should take to benefit from Social Media use to become more entrepreneurial and achieve higher organizational performance, developing and nurturing competitive advantages. The paper analyses data obtained from a sample of 201 technological firms located in Spain. The methodology used is Structural equation modelling with LISREL analysis. Findings confirms how the use of Social Media tools positively impacted all the different dimensions of corporate entrepreneurship, translating also in enhanced performance. This paper contributes to the literature by empirically confirming in a structural model how Social Media use helps to create business value, by enhancing proactive behaviours, promoting strategic renewal inside the firm and increasing innovativeness and new business venturing and displaying the internal and sequential relationships among these dimensions.Universidad de Málaga.

Solvent-Free Continuous Operations Using Small Footprint Reactors: A Key Approach for Process Intensification
A solvent-free approach to intensification of chemical processes is reported. This concept, in which reactions are carried out solvent-free, without the need for further downstream processing, was highlighted first with a full reduction of ethyl nicotinate to ethylpiperidine-3-carboxylate under continuous flow conditions. Using a small footprint reactor, a throughput of 26.4 g h–1 was achieved. Similarly, this approach was used for the telescoped two-step synthesis of 2-propyl phenol (productivity 120 g h–1) and 2-propyl cyclohexanone (productivity 30 g h–1), starting from the commercially available allyl phenol ether via Claisen rearrangement and subsequent reduction.We would like to thank Pfizer Worldwide Research & Development (CB), the EPSRC (RJM, SVL, Grant Codes EP/K009494/1, EP/M004120/1 and EP/K039520/1) and the Woolf Fisher Trust (DEF) for financial support.This is the final version of the article.

Going beyond the curve: Strategic measures to recover hotel activity in times of COVID-19
Hospitality firms are facing unprecedented challenges on a global scale. The catastrophic effects of the COVID-19 pandemic and its multiple devastating global consequences have initiated a profoundly disruptive transformation in the hospitality sector, as firms attempt to adapt their activity to the current uncertain scenario. This study draws on the crisis management literature to identify the key drivers of hotel recovery in the event of a disaster or an external crisis, like current pandemic. A sample of 237 Spanish hotel managers evaluated and ranked the strategic measures. Based on this evidence, measures were statistically examined to identify which ranked as most significant in helping hospitality managers. The results yield valuable theoretical and practical insights to guide hospitality managers towards business adaptation and recovery by highlighting key strategic measures for implementation in the short term.Funding for open access charge: Universidad de Málaga / CBUA.

Identificación inicial de genes en Babesia bigemina mediante análisis de Etiquetas de Secuencia Expresadas en el estadio intraeritrocítico del parásito
In this study, Expressed Sequence Tags (EST) were obtained and analyzed from 2208 randomly selected clones containing plasmids with cDNA inserts derived from a Babesia bigemina library. The obtained sequences were extracted and subject to Blast homology search in the Genbank databases. Sequence homology analysis resulted in the identification of 470 clones (grouped in 267 distinct clusters) which contained EST with no significant sequence identity with Babesia sp genes or other Apicomplexan parasites. Presumably, these EST would correspond either to new, unreported B. bigemina transcribed genes present in the erythrocyte stages of the parasite, or to non-translated sequences of the putative genes. 21 clones were identified which contained EST corresponding to 6 genes coding for B. bigemina antigens already reported in the literature; 1285 clones (grouped in 159 clusters of distinct sequences) had significant sequence identity with genes coding for hypothetical proteins previously identified in the Babesia bovis genome. Moreover, 32 clones had EST corresponding to 16 different Theileria sp. genes; 51 clones (26 distinct sequences) showed EST with sequence similarity to genes of Plasmodium sp., 25 EST had low identity with 13 different Toxoplasma gondii genes; and 4 clones with EST for 4 different Cryptosporidium sp genes. The results obtained, in addition to EST analysis of a larger number of B. bigemina cDNA clones, will allow the characterization and, eventually, the manipulation of gene coding regions, essential for the establishment of improved control strategies for cattle babesiosis caused by B. bigemina.En este estudio se realizó el análisis de Etiquetas de Secuencias Expresadas (EST) obtenidas a partir de 2208 clonas de Escherichia coli, con plásmidos recombinantes conteniendo insertos de cDNA de Babesia bigemina. Las secuencias se analizaron mediante búsqueda de homología en las bases de datos de genes. El análisis de homología en secuencia permitió identificar 470 clonas (agrupadas en 267 clusters) conteniendo EST con similitud de secuencia estadísticamente no significativa con algún gen de Babesia spp o de otro organismo Apicomplexa, sugiriendo la presencia de genes nuevos de B. bigemina; Se identificaron 21 clonas con EST correspondientes a 6 secuencias de genes previamente reportados para B. bigemina; además de 1285 clonas (conformando 159 clusters de genes distintos) de identidad significativa con proteínas hipotéticas o correspondientes a genes ya reportados en el genoma secuenciado de Babesia bovis; 32 clonas con EST homólogas a 16 genes distintos de Theileria spp; 51 clonas (26 genes distintos) con similitud en secuencia a genes de Plasmodium spp; 25 clonas con EST de moderada similitud con 13 genes distintos genes de Toxoplasma gondii; y 4 clonas con EST de mayor identidad con 4 genes diferentes de Cryptosporidium spp. Los resultados obtenidos permiten elaborar una base de datos sobre EST del estadio intraeritrocítico de Babesia bigemina, información básica esencial para la caracterización molecular del parásito, que permite llevar a cabo la identificación y regulación de nuevas regiones génicas codificadoras y, eventualmente el establecimiento de nuevas estrategias de control de la babesiosis bovina causada por B. bigemina
