El artículo plantea que la presencia de los partidos políticos, como estructura privilegiada de representación en los regímenes poliárquicos y de control de la organización interna del Legislativo, puede conllevar cierta limitación del efecto de control mutuo y división del poder que implica el bicameralismo. Se trata de un trabajo exploratorio que busca responder a una cuestión básica, es decir, establecer los grados de correspondencia partidista que tienen las Cámaras de los países latinoamericanos a través del análisis de sus composiciones. ; [EN] The article argues that the presence of political parties as privileged structures of representation in polyarchical regimes and of control of the internal organisation of the Legislative branch, can generate certain limitations on the mutual control and division of powers implicit in bi-cameral systems. The article compares and analyses degrees of difference and similarity in the party composition of the different chambers in Latin American political systems.

Juan Latino was the most important poet in Latin language in the spanish city of Granada during the Renaissance. In this study we discuss the social, political, religious and cultural context in which he lived. These historical aspects were of great relevance in the author's life and work, which itself shows the effect of his relations with the city's powerful institutions and authorities. ; En este trabajo se analiza el medio ciudadano, político, espiritual y cultural en que se desarrolla la vida de Juan Latino, el poeta en lengua latina más importante de la Granada renacentista. Estas circunstancias históricas tuvieron gran importancia en el autor y en su obra, que refleja además las instancias de poder que en él influyeron.

Purpose
This study aims to investigate the impact of utilitarian, hedonic and social emotional mechanics in gamified digital platforms on the components of value co-creation.


Design/methodology/approach
Hypotheses are proposed to test the emotional mechanics of gamification as antecedents of value co-creation in terms of the components of the DART (dialogue, access, risk assessment, transparency) model. The Nike+ gamified digital platform is used as the context for the empirical analysis. The hypothesis testing is performed from the consumer perspective, with data gathered using a questionnaire sent to users of the Nike+ application.


Findings
The social emotional mechanics of gamification have a positive impact on the value creation components of dialogue, access, transparency and risk. Utilitarian and hedonic mechanics also exert an impact on the value creation component of access. This study contributes to the value co-creation literature. The findings also reveal the role of customer emotions in embracing gamified platforms in a business-to-business-to-consumer (B2B2C) ecosystem.


Practical implications
Practitioners and consumers in B2B2C ecosystems can gain insight into how to interact in digital gamified platforms and how to co-create value. This study shows the importance of customers' emotional mechanics when participating in gamified platforms. The results can help organisations ensure the success of their value co-creation processes.


Originality/value
This paper proposes a combination of approaches that have traditionally been studied in isolation, placing emotions at the heart of the value co-creation paradigm.

Purpose
This paper aims to present a comprehensive framework that integrates the emerging trends of servitization and digitalization in manufacturing. The influence between digitalization and servitization is defined and quantified. Their contribution to firm performance is analyzed.


Design/methodology/approach
This paper presents a theoretical model that captures the relationships between the analyzed variables. Drawing on the Spanish Business Strategy Survey, hypothesis testing is conducted using data on 828 Spanish industrial firms. Linear regression models are built to capture the effect of each variable on firm performance and the type of interaction between the variables.


Findings
Servitization and digitalization are positively related to firm performance. Digitalization positively mediates the relationship between servitization and firm performance. The mediating effect of digitalization contributes to differentiating between the direct and indirect effects of servitization on firm performance.


Practical implications
The paper provides a useful analysis framework for firms to evaluate servitization and digitalization as success strategies. It is proposed that firms must simultaneously commit to digital transformation and the incorporation of services to create value, especially in business-to-business settings. Servitization and digitalization interact to exert a greater influence on performance.


Originality/value
The paper contributes to the theory on service strategy by providing an analysis model that includes digitalization as a mediator of the relationship between servitization and firm performance. Digitalization may provide a mechanism to unlock the benefits of servitization and thereby enhance firm performance.

The digitalization and servitization of manufacturing lead to competitive advantages through innovative digital business models. The increase in competition has led many manufacturers to search for customized solutions through servitization. In the present study, a systematic review of literature informs on how the field is structured and the key concepts are defined.

The origin and development of unmanned aviation has been almost matched that of manned aviation, starting both from an almost common point. As in conventional manned aviation, military applications, have been the motor of technological development and the potential applications of these types of systems throughout much of the twentieth century and early twenty-first century. Finally it has been in relatively recent times that these systems are experiencing an impressive boom due to the discovery of the wide variety of commercial and civil operations that are able to perform very effectively. This paper attempts to summarize the historical evolution that these systems have suffered and in the end, to present a quick analysis of the major civil / commercial applications, trying to provide an overview of the main types of systems, their classification and general configuration. ; Peer Reviewed

This work forms part of the doctoral thesis conducted by David Sánchez Porras (Doctoral Program in Biomedicine, Doctoral School, University of Granada, Spain). ; Considering the high prevalence of cartilage-associated pathologies, low self-repair capacity and limitations of current repair techniques, tissue engineering (TE) strategies have emerged as a promising alternative in this field. Three-dimensional culture techniques have gained attention in recent years, showing their ability to provide the most biomimetic environment for the cells under culture conditions, enabling the cells to fabricate natural, 3D functional microtissues (MTs). In this sense, the aim of this study was to generate, characterize and compare scaffold-free human hyaline and elastic cartilage-derived MTs (HC-MTs and EC-MTs, respectively) under expansion (EM) and chondrogenic media (CM). MTs were generated by using agarose microchips and evaluated ex vivo for 28 days. The MTs generated were subjected to morphometric assessment and cell viability, metabolic activity and histological analyses. Results suggest that the use of CM improves the biomimicry of the MTs obtained in terms of morphology, viability and extracellular matrix (ECM) synthesis with respect to the use of EM. Moreover, the overall results indicate a faster and more sensitive response of the EC-derived cells to the use of CM as compared to HC chondrocytes. Finally, future preclinical in vivo studies are still needed to determine the potential clinical usefulness of these novel advanced therapy products. ; Instituto de Salud Carlos III Spanish Government FIS PI17/0393 PI20/0318 ; Junta de Andalucia PI-0257-2017 PE-03952019 ; Junta de Andalucia P18-RT-5059 ; University of Granada A-CTS-498-UGR18 ; Junta de Andalucia A-CTS-498-UGR18 ; FEDER-ERDF funds

Some species of the genus Pseudo-nitzschia produce the toxin domoic acid, which causes amnesic shellfish poisoning (ASP). Given that bivalve mollusks are filter feeders, they can accumulate these toxins in their tissues. To elucidate the transcriptional response of the queen scallop Aequipecten opercularis after exposure to domoic acid-producing Pseudo-nitzschia, the digestive gland transcriptome was de novo assembled using an Illumina HiSeq 2000 platform. Then, a differential gene expression analysis was performed. After the assembly, 142,137 unigenes were obtained, and a total of 10,144 genes were differentially expressed in the groups exposed to the toxin. Functional enrichment analysis found that 374 Pfam (protein families database) domains were significantly enriched. The C1q domain, the C-type lectin, the major facilitator superfamily, the immunoglobulin domain, and the cytochrome P450 were among the most enriched Pfam domains. Protein network analysis showed a small number of highly connected nodes involved in specific functions: proteasome components, mitochondrial ribosomal proteins, protein translocases of mitochondrial membranes, cytochromes P450, and glutathione S-transferases. The results suggest that exposure to domoic acid-producing organisms causes oxidative stress and mitochondrial dysfunction. The transcriptional response counteracts these effects with the up-regulation of genes coding for some mitochondrial proteins, proteasome components, and antioxidant enzymes (glutathione S-transferases, thioredoxins, glutaredoxins, and copper/zinc superoxide dismutases) ; This work has been supported by the Spanish Ministry MINECO (Ministerio de Economía y Competitividad) and the FEDER Funds (European Regional Development Fund) of the European Union under the project AGL2012-39972-C02 ; SI
