La clave es la metodología: cuando las apariencias no engañan
Authors: González Calatayud Víctor 
Published: December 2022

Cuando hablamos del avance de la sociedad, hablamos ineludiblemente de la investigación como eje central para mejorar. A partir de esta conseguimos evitar mitos, solucionar problemas, conocer aspectos sociales esenciales, etc. No obstante, para la realización de una investigación de calidad, en todas las áreas de conocimiento incluida la Tecnología Educativa, se requiere de una metodología acorde a la pregunta de investigación, al contexto donde nos ubicamos, a los datos que se pueden recoger y a una serie de características que permitan realmente desarrollar un trabajo de calidad. Es por ello por lo que en este monográfico se recogen artículos que trabajan a nivel teórico métodos novedosos -o no tan novedosos- para que sirvan de base para futuras investigación. A partir de estos artículos el lector se adentra en el conocimiento en profundidad de revisiones sistemáticas, investigación mixta, cualitativa y el método fenomenográfico. Pero no solo eso, sino que además el monográfico incluye investigación aplicada en este sentido para que sirva como ejemplo de dichas técnicas. En general, se trata de un número que pretende ser la base para la investigación en el campo de la Tecnología Educativa.
When we discuss the advancement of society, we inevitably talk about research as a central axis for improvement. Through research we manage to avoid myths, solve problems, learn about essential social aspects, etc. However, in order to carry out quality research in all areas of knowledge, including Educational Technology, a methodology is required in accordance with the research question, the context in which we are located, the data that can be collected and a series of characteristics that allow us to really develop quality work. For this reason, this monograph includes articles that work at a theoretical level on new -or not so new -methods to serve as a basis for future research. These articles provide the reader with in-depth knowledge of systematic reviews, mixed and qualitative research and the phenomenographic method. Not only that, but the monograph also includes applied research in this area to serve as an example of these techniques. Overall, this is an issue that is intended to be the basis for research in the field of Educational Technology.
The Rights Retention Policy of Edinburgh University
Authors: Tate Dominic , Aspaas Per Pippin 
Published: December 2022

As the first UK institution, Edinburgh University adopted a Rights Retention Policy on 1st January 2022. As a result, all research articles written by Edinburgh’s researchers can now be made legally available in open access immediately upon publication in a journal or a volume of conference proceedings. In this episode, head of Library Research Support at Edinburgh University Library, Dominic Tate explains how the policy came into being and how it has been received by academic publishers.
In addition to Plan S, the 41 recommendations as stated in an Open Science Roadmap developed by a working group within LERU (League of European Research Universities) served as inspiration for the latest revision of the Open Access Policy at Edinburgh University. The institution has had an institutional repository in place for two decades and most researchers are routinely depositing their articles there. The next step was to enable these articles (usually in the form of the Author's Accepted Manuscript, AAM) to be made immediately available in open access without any embargo periods or other restrictions. About 160 publishers have received prior notice about Edinburgh’s rights retention policy and the reception has been overwhelmingly positive.

Background
Sports mouthguards, worn in the oral cavity to prevent sports injuries, are constantly exposed to various microorganisms that cause oral infections. Hence, the optimal cleaning methods for sports mouthguards have been thoroughly examined. In this study, we evaluated the efficiency of cleaning effects with a mouthguard cleaner (MC) on microbial biofilm formation in sports mouthguards in vitro and in vivo.

Methods
We evaluated the cleaning effects of the discs produced by ethylene-vinyl acetate (EVA) on bacterial biofilms formed by the commensal bacterium Streptococcus oralis, the cariogenic bacterium Streptococcus mutans, and the opportunistic pathogen Staphylococcus aureus in vitro. EVA discs with biofilm were subjected to sterile distilled water (CTRL) and ultrasonic washing (UW), followed by treatment with MC and sodium hypochlorite (NaClO) as positive controls. Thereafter, the viable bacterial cell counts were determined. The bacteria adhering to the sheets before and after the treatment were observed under an electron microscope. The degree of cleanliness and measurement of viable microbial cell counts for total bacteria, Streptococci and Candida, opportunistic fungi, were evaluated on the used experimental sports mouthguards with and without UW and MC treatment in vivo.

Results
The number of bacterial cells significantly decreased against all the tested biofilm bacteria upon treatment with MC, compared with CTRL and UW. Electron microscopy analysis revealed the biofilm formation by all bacteria on the EVA discs before cleaning. We observed fewer bacteria on the EVA discs treated with MC than those treated with CTRL and UW. Furthermore, the degree of cleanliness of the used experimental sports mouthguards cleaned using MC was significantly higher than that of the CTRL-treated mouthguards. Moreover, the viable microbial cell counts on the used experimental sports mouthguard were considerably lower than those on the CTRL ones.

Conclusion
The cleaning effect of MC against oral bacteria was more effective than that of UW. MC treatment might have a potential future application as a cleaning method for sports mouthguards to protect athletes from oral infection.

Field experiments were conducted during rainy seasons of 2018 to 2020 at Regional Rice Research Station, Navsari Agricultural University, Vyara, Gujarat on clayey soils. The treatment consists of four rice varieties i.e., Purna, GR 5, GNR 6 and IR 28 with 100 % and 50 % recommended dose of N through FYM. Result showed that significantly higher plant height recorded in variety GR 5 which was at par with variety Purna. Highest panicle m-2 were recorded in variety Purna followed by GR 5. Significantly higher grain yield was recorded in variety Purna which was statistically at par with variety GR 5. Significantly higher straw yield was recorded in variety GR 5 which was statistically at par with variety Purna. The treatment consists of application of 100% and 50% recommended dose of Nitrogen through farmyard manure recorded non significant difference. Hence, farmers of south Gujarat, growing direct seeded upland rice (Purna or GR 5) organically are needs to apply 37.5 kg N ha-1 (50% recommended dose of Nitrogen) through farmyard manure for achieving profitable yield.

Published: December 2022

Objective and Background: A study was carried out to assess and generate the prediction maps of the physicochemical properties of the soil in the Kishtwar district. The Kishtwar district of Jammu and Kashmir covers an area of 7737 sq. km. and falls in the temperate zone of the state. It is an upland valley in the northeast corner of the Jammu region.
Methods: Soil samples were collected from the entire Kishtwar district in a stratified random manner. The digitization process and generation of maps were carried out with ArcGIS 10.0.
Results: Sandy loam was the dominant textural class in the district. Soil pH varied widely across the Kishtwar district ranging from as low as 4.87 to as high as 8.00, with a mean value of 6.73. The coefficient of variation CV (coefficient of variation) was 8.08%. Electrical Conductivity (EC) ranged from 0.03 to 9.80 dS m-1 with a mean value of 1.50 dS m-1. The variability of Electrical Conductivity (EC) was high. Organic carbon (OC) ranged from 0.20 to 2.68%, with a mean value of 1.18% with a coefficient of variation (CV) of 48.14%. Calcium carbonate went from traces to 3.60% with a mean value of 0.79% and had a high variability with a CV of 90.38%. Cation exchange capacity (CEC) ranged from 2.50 to 29.40 cmol p+/kg with a mean value of 17.14 and CV of 39.79%.
Conclusion: Almost all recorded physicochemical properties of Kishtwar district soils were conducive to crop growth. However, the major area of the district was either devoid of cultivation or difficult to cultivate because the region has undulating topography.
Association of Recreational Cannabis Legalization With Cannabis Possession Arrest Rates in the US
Authors: Gunadi Christian , Shi Yuyan 
Published: December 2022

ImportanceRecreational cannabis legalization (RCL) has been advocated as a way to reduce the number of individuals interacting with the US criminal justice system; in theory, however, cannabis decriminalization can achieve this objective without generating the negative public health consequences associated with RCL. It is still unclear whether RCL can bring additional benefits in terms of reducing cannabis possession arrests in states that have already decriminalized cannabis.ObjectiveTo examine whether RCL was associated with changes in cannabis possession arrests in US states that had already decriminalized cannabis during the study period and whether these changes differed across age and racial subgroups.Design, Setting, and ParticipantsThis repeated cross-sectional study used cannabis possession arrest data from the Federal Bureau of Investigation Uniform Crime Reporting Program (UCRP) for US states from 2010 through 2019. Statistical analysis was conducted from October 6, 2021, to October 12, 2022.ExposuresImplementation of statewide RCL.Main Outcomes and MeasuresCannabis possession arrest rates per 1000 population per year were assessed with a quasi-experimental difference-in-differences design and were used to estimate the association of RCL with arrest rates in RCL states that had or had not decriminalized cannabis before RCL. This association was also examined in subgroups for age (adults vs youths) and race (Black vs White).ResultsThis study included UCRP data for 31 US states, including 9 states that implemented RCL during the study period (4 without and 5 with decriminalization) and 22 non-RCL states. In the 4 states that had not decriminalized cannabis before legalization, RCL was associated with a 76.3% decrease (95% CI, −81.2% to −69.9%) in arrest rates among adults. In the 5 states that had already decriminalized cannabis, RCL was still associated with a substantial decrease in adult arrest rates (−40.0%; 95% CI, −55.1% to −19.8%). There was no association of RCL with changes in arrest rates among youths. In addition, changes in arrest rates associated with RCL did not differ among Black and White individuals.Conclusions and RelevanceIn this repeated cross-sectional study, RCL was associated with a sizable reduction in cannabis possession arrests among adults in states that had already decriminalized cannabis during the study period (2010-2019), albeit the magnitude was smaller compared with states that had not decriminalized cannabis before RCL. In addition, RCL did not seem to be associated with changes in arrest rates among youths or disparities in arrest rates among Black and White individuals.

Published: December 2022

AbstractShort‐circuit defects caused by microscale dust particles in organic light‐emitting diodes (OLEDs) cause a decrease in production yield and hinder cost reduction. An organic layer coating by solution process is used to prevent short‐circuit defects of particles on a substrate. In this study, the coverage properties of a coated organic layer on size‐controlled particles are revealed. The surface of the substrate with size‐controlled SiO2 particles with a diameter of 0.2–5 µm is quantitatively contaminated, and the particle coverage properties of the solution‐processed hole injection layer are investigated. From the results of the leakage current measurement and cross‐sectional observation by a transmission electron microscope, it is observed that devices with 50 nm‐spin‐coated poly (3,4‐ethylenedioxythiophene): poly(styrene sulfonate) can cover SiO2 particles up to 1 µm in diameter without any increase in leakage current. It is revealed that larger‐sized particles cause electric defects, albeit with a low probability, owing to the larger space under the particles. To fabricate OLEDs with a high yield, the shape of the coverage at the bottom of the particle is important in preventing electric defects. The results of this study are useful not only for OLEDs but also for printed and coated devices.

Published: December 2022

AbstractElectrophoretic deposition (EPD) of colloidal particles is a practical system for the study of crystallization and related physical phenomena. The aggregation is driven by the electroosmotic flow fields and induced dipole moments generated by the polarization of the electrode‐particle‐electrolyte interface. Here, the electrochemical control of aggregation and repulsion in the electrophoretic deposition of colloidal microspheres is reported. The nature of the observed transition depended on the composition of the solvent, switching from electrode‐driven aggregation in water to electrical field‐driven repulsion in ethanol for otherwise identical systems of colloidal microspheres. This work uses optical microscopy‐derived particles and a recently developed particle insertion method approach to extract model‐free, effective interparticle potentials to describe the ensemble behavior of the particles as a function of the solvent and electrode potential at the electrode interface. This approach can be used to understand the phase behavior of these systems based on the observable particle positions rather than a detailed understanding of the electrode‐electrolyte microphysics. This approach enables simple predictability of the static and dynamic behaviors of functional colloid‐electrode interfaces.

AbstractAntibiotic‐resistant infections caused by bacterial pathogens pose a serious threat to public health, hampering wound healing and causing significant morbidities worldwide. A biomedical fiber‐device that functions as a drugless antiseptic is introduced as a solution to this problem. Through stitching, piercing, or topical application to the wound, this fiber slows down the proliferation of pathogenic bacteria, thereby reducing the risks associated with inflammation and inhibiting infections. The fiber's bacterial proliferation inhibition function is based on the galvanic effect, which disturbs bacterial quorum sensing. Detailed herein are the fiber design optimization, scalable fabrication approach, electrical function characterization, and antiseptic function verification in cultures of typical wound pathogens. Such a fiber—mechanically and environmentally resilient, insensitive to harsh storage conditions with nominally infinite shelf‐life, resulting from machining rather than pharmacochemical fabrication— provides a cost‐effective and widely available alternative to current antibiotic treatments of physical injury.

Published: December 2022

AbstractSwimmers that can convert external energy to dynamic movement have shown great potential in different fields; however, their applications are restrained due to the demerits of high cost, environmental pollution, and low efficiency in exiting propelling methods. Herein, droplets are proposed to use whose motions are restricted to fixed positions or specified areas to propel a superhydrophobic swimmer with a superhydrophilic wedge‐shaped pattern effectively. This propelling method by restricted droplets can more effectively convert droplet surface energy to kinetic energy of the superhydrophobic swimmer, thereby achieving high‐efficient propulsion of the swimmer. The propelling mechanism and propelling force are analyzed in detail, and the movement of the swimmer can be controlled by parameters including wedge angle, droplet volume, and needle size. Based on the propelling phenomenon, an accelerator is further developed to promote the hanging droplets to move along specific tracks, and thereby achieve rapid movement of superhydrophobic swimmers on the water surface. In addition, superhydrophobic swimmers capable of reciprocating and precise movement control including position and direction are also designed, which may provide new strategy for movement control of microdevices in intelligent systems.

AbstractTwo‐dimensional (2D) conductive metal‐organic frameworks (MOF) represent a unique class of electrode materials with high capacity and power density. Understanding molecular mechanisms and pathways for heterogeneous nucleation of 2D π‐conjugated MOFs is highly desirable for controlling the structure and properties of conductive MOFs on solid substrates. Herein, a systematic study of nucleation and growth of 2D π‐conjugated Ni‐catecholate (Ni‐CAT‐1) MOFs on highly oriented pyrolytic graphite (HOPG) and copper substrates is reported. It is discovered that the nucleation density and growth kinetics of the MOF film can be controlled by varying substrate interactions with the organic linker. Specifically, π–π interactions between the linker and the HOPG dictate lower nucleation density, whereas π–metal interactions between the linker and the copper substrate dictate faster nucleation and higher nucleation densities. These studies reveal the key mechanism for Ni‐CAT‐1 nucleation on different surfaces and provide insights into interfacial control over the growth of other 2D π‐conjugated MOF films on solid substrates to inform synthesis of functional materials.

AbstractTextiles containing interposed layers of polyethylene oxide (PEO)‐fibrinogen and PEO‐thrombin fibers are explored as biomaterials for hemostasis. The PEO‐fibrinogen and PEO‐thrombin fibers are formed by contact drawing, an approach that uses an entangled polymer solution and a pin array to form fibers by extension of liquid bridges. The interposition of the PEO‐fibrinogen and PEO‐thrombin fibers results in polymerization of a fibrin hydrogel mesh once the textile is hydrated. This fibrin hydrogel mesh displays the expected bands and diffraction peaks by Fourier‐transform infrared spectromicroscopy and X‐ray diffraction, respectively. The functionality of the hemostatic textiles formed from the interposed PEO‐fibrinogen and PEO‐thrombin fibers is demonstrated by analyzing human blood hemolysis, complement activation, protein adsorption, and platelet and leukocyte adhesion, indicating compatibility with human blood (hemolysis ratio <5%), with minimal inflammatory response (levels of terminal complement complex equivalent to plasma). The cytocompatibility and potential for cell remodeling of the fibrin hydrogel mesh formed by this process is evaluated with human dermal fibroblasts and human keratinocytes and it is found that both cell types attach and grow on the fibrin mesh. Finally, a whole blood clotting time of less than 30 s suggests a potential use of this material in hemorrhage control.

AbstractLaboratory‐controlled conditions, spin‐coating method, and non‐ecofriendly halogenated solvents that have been employed for higher‐performance organic solar cells (OSCs) are not compatible with large‐scaled, roll‐to‐roll (R2R) manufacturing in ambient conditions. Slot‐die coating is a viable upscaling method, but the investigation of slot‐die‐coated OSCs is still rare, especially OSCs with all functional layers deposited with non‐halogenated solvents in air. Herein, all slot‐die coated devices are successfully manufactured by sequentially slot‐die coating the hole transport layer (PEDOT:PSS), the photoactive layers (PM6 and BTP‐4F‐12 (Y6‐C12)), and the electron transport layer (PFN‐Br). Because of solubility variation of photoactive components in non‐halogenated solvents (o‐Xylene and 2‐methyltetrahydrofuran (2‐MeTHF)), two bilayer‐processed photoactive films have been obtained via different solvent combinations (o‐Xylene/o‐Xylene for PM6 (o‐Xylene)/Y6C12 (o‐Xylene) and o‐Xylene/2‐MeTHF for PM6 (o‐Xylene)/Y6C12 (2‐MeTHF)). Different morphologies of bilayer‐processed photoactive films influence exciton dissociation and charge extraction properties of corresponding devices. Finally, the device hosting o‐Xylene/o‐Xylene processed photoactive film has a superior efficiency (10.6%) than the o‐Xylene/2‐MeTHF processed photoactive film‐based device (7.2%). Differently from device efficiency, the device based on o‐Xylene/2‐MeTHF processed photoactive film exhibits the preferable storage stability.
