Ethics and social responsibility in archival institutions: elements to consider
[ES] Consideraciones sobre la ética y sobre la responsabilidad social de las entidades archivísticas, con el objetivo de que completen
los códigos éticos de la actividad en la gestión documental que se centra en el comportamiento ético de las personas.
La metodología se basa en el conocimiento de casos del autor, por su larga trayectoria como profesional archivero, tanto
de archivos administrativos como de históricos. La originalidad del estudio reside en la propuesta de elementos éticos y de
responsabilidad social desde el punto de vista de la entidad y no del comportamiento del personal, que podrá ayudar a estas
entidades a ampliar su código ético y a formular nuevas estrategias para beneficiar a la comunidad.[EN] This article proposes ethical and social responsibilities for archival institutions to supplement the ethical codes for records management that focus on individual ethical behavior. The methodology is based on case studies, from the author¿s long career as professional archivist in administrative and historical archives. The original contributions of this study are ethical and social responsibility proposals from the perspective of archival institutions, not the staff, which could help these institutions extend their ethical code and formulate new strategies to benefit the community.Gimenez-Chornet, V.

Synthetic Routes for Designing Furanic and Non Furanic Biobased Surfactants from 5-Hydroxymethylfurfural
[EN] 5-hydroxymethylfurfural (HMF) is one of the most valuable biomass platform molecules, enabling the construction of a plethora of high value-added furanic compounds. In particular, in the last decade, HMF has been considered as a starting material for designing biobased surfactants, not only because of its renewability and carbon footprint, but also because of its enhanced biodegradability. This Review presents recent examples of the different approaches to link the hydrophilic and lipophilic moieties into the hydrophobic furan (and tetrahydrofuran) ring, giving a variety of biobased surfactants that have been classified here according to the charge of the head polar group. Moreover, strategies for the synthesis of different non-furanic structures surfactant molecules (such as levulinic acid, cyclopentanols, and aromatics) derived from HMF are described. The new HMF-based amphiphilic molecules presented here cover a wide range of hydrophilic-lipophilic balance values and have suitable surfactant properties such as surface tension activity and critical micelle concentration, to be an important alternative for the replacement of non-sustainable surfactants.This work has been supported by the Spanish government through the "Severo Ochoa Program" (SEV-2016-0683) and the PGC2018-097277-B-100 (MCIU/AEI/FEDER, UE) project.Velty, A.; Iborra Chornet, S.; Corma Canós, A.

Archivos electrónicos. Criterios de preservación con la norma UNE-ISO 14641-1
La norma UNE-ISO 14641-1 reúne unos criterios de buenas prácticas para la preservación de los documentos digitales o electrónicos que las organizaciones producen como consecuencia de su actividad. Se pretende que estos documentos electrónicos se puedan consultar en un futuro con todas la garantías de autenticidad e integridad, para que continúen disponiendo el mismo valor legal o informativo que cuando se produjeron.Giménez Chornet, V.
