El presente estudio tiene como objetivo desarrollar un modelo estadístico que definan cuáles son los atributos de calidad (intrínsecos y extrínsecos) y de creencia que influye en la intención de compra de las bebidas gasificadas, de la población con un nivel socioeconómico C, C+ de Hermosillo Sonora. El diseño de la metodología de esta investigación se realizó en dos actuaciones: 1) cualitativa, la cual está dividida en dos partes, entrevistas de profundidad y sesiones de grupo; y 2) cuantitativa, se aplicó un cuestionario estructurado para la recopilación de datos y por medio de la técnica estadística de los modelos de ecuaciones estructurales se contrastaron las hipótesis de trabajo. Los resultados demuestran que los atributos extrínsecos son un factor importante para el consumo de bebidas gasificadas.

Community-based participatory research (CBPR) is challenging to research ethics committees (RECs). We reviewed the REC preparedness when reviewing CBPR projects. We searched the MEDLINE database and included qualitative studies of CBPR researchers or REC members about their experiences with RECs. The search yielded 107 studies, of which 10 met our criteria. Barriers were that the community is not prepared to conduct research, the reluctance of RECs to work outside the university, the difficulty RECs have understanding CBPR, and that REC forms evaluate individual rather than community risk. Facilitators were having a CBPR expert as an REC member and educating RECs. Therefore, RECs are not prepared to evaluate CBPR projects leading to unnecessary delays in the approval process.

Bio-based insulation materials (such as wood or hemp) are emerging as a promising alternative in building envelope applications, aiming at improving in-use energy efficiency. When compared to common insulation materials (rock and glass wool or petrol-based foams) bio-based materials present the advantage of being renewable, with a low embodied energy and CO2 neutral or negative. Moreover, these materials have a distinct hygrothermal performance, as the sorption/desorption of water vapour in their porous structure, in dynamic equilibrium with their surrounding environment, constantly modifies their hygric and thermal properties while causing energy transfers itself. In this paper, the hygrothermal performance of two different bio-based materials in outdoor conditions is evaluated. The first is an innovative light-weight composite made from corn pith and alginate. The second a commercially available wood insulator. The materials are tested alone and as components of external thermal insulation systems (ETICS) and compared to a conventional polystyrene foam. The results show how the sorption process influence the hygrothermal performance of the materials when the surrounding conditions are modified. When subjected to cyclic changes in temperature and relative humidity, the bio-based materials tested show a lower temperature variation than polystyrene. This is in part due to their lower thermal diffusivity, but also to the water absorption and desorption mechanisms occurring within the materials, which were measured by the change in mass of the materials during the tests. The differences in the thermal performance were more noticeable when the insulation materials were tested alone than when these were tested as a part of an ETIC System. ; This work was funded by MINECO (Spain) and AEI/FEDER/UE under the projects BIA2014-52688-R, BIA2017-88401-R and ENE2015-64117-C5-3-R.

[EN] Precision medicine has emerged as a disrupting medical model to transform a historically reactive medicine into a proactive one that focuses on delivering individualized treatment. A relevant challenge of precision medicine is to integrate the large amount of omics data that exists. This data has a high degree of heterogeneity, dispersion, and isolation. In addition, there is a lack of a solid ontological commitment regarding domain concepts and definitions, and a unified guideline of how to transform data into knowledge is missing. In this work, we report our experience applying conceptual modeling to deal with these challenges in a specific genomics dimension, i.e., Precision Medicine. To do so, we have applied conceptual modeling techniques. The use of these techniques allows us to create representations of the world (i.e., conceptual schemes) that can be used for the purposes of understanding, communicating, and problem-solving. They also help to establish a common ontological framework to facilitate both communication and knowledge evolution in complex domains. We identify a set of limitations that emerged after working in a precision medicine context, and we describe how we have solved them using conceptual modeling. Thus, the main contribution of this work is to present the subsequent Conceptual Schema that allowed us to overcome these limitations, which provides a better representation of proteomics data and eases its integration. ; This work was supported in part by the Spanish State Research Agency and the Generalitat Valenciana under Project PROMETEO/2018/176, Project PDC2021-121243-I00, and Project INNEST/2021/57; and in part by the European Regional Development Fund (ERDF) and the European Union NextGenerationEU/PRTR. ; García-Simón, A.; León-Palacio, A.; Reyes Román, JF.; Casamayor Rodenas, JC.; Pastor López, O.
