4to. Congreso Internacional de Ciencia, Tecnología e Innovación para la Sociedad. Memoria académica

Este volumen acoge la memoria académica de la Cuarta edición del Congreso Internacional de Ciencia, Tecnología e Innovación para la Sociedad, CITIS 2017, desarrollado entre el 29 de noviembre y el 1 de diciembre de 2017 y organizado por la Universidad Politécnica Salesiana (UPS) en su sede de Guayaquil. El Congreso ofreció un espacio para la presentación, difusión e intercambio de importantes investigaciones nacionales e internacionales ante la comunidad universitaria que se dio cita en el encuentro. El uso de herramientas tecnológicas para la gestión de los trabajos de investigación como la plataforma Open Conference Systems y la web de presentación del Congreso http://citis.blog.ups.edu.ec/, hicieron de CITIS 2017 un verdadero referente entre los congresos que se desarrollaron en el país. La preocupación de nuestra Universidad, de presentar espacios que ayuden a generar nuevos y mejores cambios en la dimensión humana y social de nuestro entorno, hace que se persiga en cada edición del evento la presentación de trabajos con calidad creciente en cuanto a su producción científica. Quienes estuvimos al frente de la organización, dejamos plasmado en estas memorias académicas el intenso y prolífico trabajo de los días de realización del Congreso Internacional de Ciencia, Tecnología e Innovación para la Sociedad al alcance de todos y todas

Capabilities supporting digital servitization: A multi-actor perspective

Digital transformation in business solutions is offering opportunities for servitization to become more digitalized. In this context, digital servitization requires the actors involved to perform new roles and develop new capabilities. Although servitization actor capabilities in the digital transformation context have been addressed in prior studies, the literature lacks a detailed understanding of how they operate according to different service types and different actor roles. Through a systematic literature review, our study aims to expound the capabilities required for digital servitization, for Base, Intermediate, and Advanced services, and analyze who of the main actors of the service triad (manufacturer, intermediaries, and customer) should own such capabilities. This analysis resulted in a final sample of 47 main articles addressing capabilities. We show how the structure of the service triad shifts the digital service provision based on the capabilities required by each actor. For instance, Base Services demand less capabilities, thus, intermediary actors play a less important role since they just execute services usually on behalf of a manufacturer in a more discrete capacity. For Intermediate Services, the intermediary actor becomes more important, with capabilities needed to deliver the digital solution. In Advanced Services, customers’ relationships with manufacturers become stronger, as this actor reassumes a central role in the solution offer, and intermediaries move to a supporting role again. Our analysis offers propositions for future research on digital servitization and practical implications on the capabilities required

Evaluation of the Light/Dark Cycle and Concentration of Tannery Wastewater in the Production of Biomass and Metabolites of Industrial Interest from Microalgae and Cyanobacteria

The tanning industry transforms animal skins into leather and produces liquid effluents with a high organic and inorganic pollutant load. This work evaluated the effect of the tannery wastewater (TWW) concentration and the light/dark cycle on the production of biomass, carbohydrates, proteins, lipids, and pigments (carotenoids and phycobiliproteins) on two microalgae (Chlorella sp. and Scenedesmus sp.) and one cyanobacterium (Hapalosiphon sp.). A non-factorial central experimental design with a response surface was implemented using the STATISTICA 7.0 software. High removal percentages for nitrates (97%), phosphates (73.3%), and chemical oxygen demand (93.2%) were achieved with the three strains. The results also highlight that the use of a constant light regime (24:0) and the concentration of real TWW affect the biomass production, since the highest concentration of biomass recorded was 1.31 g L−1 of Hapalosiphon sp. with 100% undiluted wastewater
