Por los últimos años, la profesión del Trabajo Social en Puerto Rico ha estado en un fuerte debate de si se debería crear una reválida para la misma. Lo interesante es que, en general, nuestro gremio profesional no simpatiza con la filosofía detrás de las reválidas. Aun así, presiones externas a la profesión han convencido a una parte del gremio sobre la necesidad de implementar una reválida, aunque vaya en contra de sus ideales. Entre dichas presiones se encuentran, por mencionar algunas: 1) Que seamos de las pocas profesiones que no revalidan; 2) Que existe la posibilidad que el Estado imponga una reválida sin nuestra consulta; 3) Que se considera que la profesión amerita tener una reválida para ganar prestigio; 4) Que urge la necesidad de establecer un filtro de los y las egresadas de las universidades para reducir las querellas éticas en el futuro y de vez regular la formación profesional. Dicho esto, el artículo reflexionará mis preocupaciones de implementarse una reválida en nuestra profesión. Entre ellas, se encuentra que podríamos terminar mercantilizando la profesión. También expongo mis inquietudes de que se establezca una reválida estilo "talla única", que tenga la intención de fracasar a los estudiantes, que homogenice los currículos, elimine el pensamiento crítico, que no sea cónsona con las inteligencias múltiples, que propicie la competencia y que sea incapaz de medir otras capacidades humanas más afines con los valores y principios de la profesión.

Full‐service sex workers (FSSWs) are at heightened risk of contracting HIV due to facing multi‐level challenges to sexual health. This study investigated factors associated with willingness to use Pre‐Exposure Prophylaxis (PrEP)—a daily HIV preventative medication, among FSSWs. Using social–ecological theory, an online survey was developed with initial guidance from a local sex worker advocacy organization to assess barriers and facilitators to PrEP uptake willingness. The survey was disseminated with the assistance of local and national sex work advocacy organizations. In our sample of FSSWs (n = 83), two barriers and two facilitators initially were associated with PrEP uptake. However, in adopting a more conservative analysis, only anticipating stigmatizing disapproval from others for using PrEP and providing others with PrEP knowledge maintained statistical significance. These two variables collectively explained nearly 30% of the variance in PrEP uptake willingness. Implications for both future research and clinical work with FSSWs are discussed.

Nanogels, due to their unique properties, have potential for promising applications in several fields. There is a growing interest in understanding which are the mechanisms controlling their properties, as those depend not only on composition but also on internal structure. In this work, dissipative particle dynamics simulations were applied to simulate the formation of nanogels from monodisperse end-functionalised polymer chains, with the cross-linking reaction modelled using a distance-based algorithm, including a reversible intermediate step. Nanogel properties are studied by calculating their swelling transition curves and structure properties, such as network defects and entanglement state. Various chain lengths, reaction schemes, nanogel in silico synthesis methods and solvent ratios are compared and discussed, showing how these factors influence the nanogel swelling behaviour and structure. Our results show that, in order to be compared with experiments, nanogel simulations should carefully consider processing parameters. ; This project has received funding from the European Union's Horizon 2020-Research and Innovation Framework Programme under the Marie Skłodowska-Curie Grant Agreement no. 642890 (http://thelink-project.eu/) and it was partially supported by the Portuguese Foundation for Science and Technology (FCT) in the framework of the Strategic Funding UIDB/04650/2020-2023, by the FCT grant SFRH/BD/128666/2017.

Aliphatic diisocyanates and their derivatives are key liquid components in the industrial processing of polyurethane materials. In particular, for the synthesis of crosslinked polyurethane materials, the higher functionality molecules obtained by reacting three -or more- diisocyanates are of interest. However, despite their widespread application, the relation between molecular structure and macroscopic physical properties, in particular viscosity, is poorly understood in these systems. In this work, we introduce a new force field parameter set, GAFF-IC, based on the widely-used and versatile GAFF force field, meant for accurate predictions of physical properties of isocyanate-based molecular liquids. The new parameters allow to predict the vaporization enthalpies and densities of several isocyanate-based molecules, which are found in excellent agreement with the available experimental data. The effectiveness and transferability of the improved parameters is verified by calculating the viscosities of several isocyanates, isocyanate dimers (uretdiones) and isocyanate trimers (isocyanurates), resulting in accurate viscosity predictions in excellent agreement with experimental values. ; This project has received funding from the European Union's Horizon 2020 research and innovation program under the Marie Sk lodowska-Curie Grant Agreement no. 642890 (http://thelink-project.eu/) and it was partially supported by the Portuguese Foundation for Science and Technology (FCT) in the framework of the Strategic Funding UID/FIS/04650/2013, and by the project "Search-ON2: Revitalization of HPC infrastructure of Uminho" (NORTE-07-0162-FEDER-0000869), under the National Strategic Reference Framework, through the European Regional Development ...
