Comparison of Isolation Methods and Physicochemical Characteristics of Starches Isolated from Red and White Sorghum Hybrids

The aim of this study is to optimize starch isolation from different sorghum cultivars and characterize the starch from fourteen red and white sorghum hybrids. Methods involving sulfite maceration and/or protein hydrolysis are assayed. Recovery and yield, residual protein, total and starch damage, whiteness index (WI), water absorption, solubility, and swelling power of isolated starches are compared in order to select the appropriate isolation method. Results indicate that starch recoveries between 44–76%. Isolated starches present 0.58–2.4 g 100 g−1 residual proteins, 89.1–90.6 WI, 5.10–9.57 g 100 g−1 solubility, and 15.09–22.57 g water 100 g−1 swelling power. Taking into account recovery, residual protein, WI, and good hydration properties of starch, the maceration during 24 h combined with protein hydrolysis during 3 h is used to isolate starches. After starch isolation, its characterization (residual protein, total and damage starch, amylose content, particle size distribution, WI, crystallinity, gelatinization temperature, water absorption, solubility, and swelling power) is performed. Principal component analysis shows that color as indicator of variety is influenced by the structure, composition, and physicochemical properties of isolated starch. Starches from white sorghum hybrids have higher amylose content and gelatinization temperature than the red ones, which affect starch solubility, and swelling power.Fil: Albarracín, Micaela.

Estrategias Didácticas en el aprendizaje de Estudios Sociales en los estudiantes de octavo año de la Unidad Educativa “Hermano Miguel”

The present research work focused on the problem where students, in spite of finding in their classrooms a certain diversity of didactic strategies, these are routine and not very motivating, which generates apathy and disinterest in them to learn social sciences. The objective was to develop didactic strategies to improve learning in the subject of social studies. For this purpose, a methodological design framed in the quantitative paradigm was used, combined with the applied research modality and the type of explanatory research. 259 students, 3 teachers and 2 authorities of the Educational Unit participated. The main results obtained corroborated the use of participation as a strategy and, as regards didactic resources, graphic organizers are the most used, which is why visits or excursions are not frequently used, thus wasting the advantages offered by this resource. In view of this, a proposal was made to improve the teaching-learning process with the use of the didactic resource of guided visits to interactive museums through micro-curricular planning, which has been validated by specialists and users, determining its feasibility. With the application of the proposal, 98% of the students make the visit, 90% understand the subject better, 86% are motivated to expand the content; 100% find paleontological and scientific museums interesting and 100% describe memories of positive emotions when visiting a virtual museumEl presente trabajo de investigación se enfocó en la problemática donde los estudiantes a pesar de encontrar en sus aulas cierta diversidad de estrategias didácticas, éstas resultan rutinarias y poco motivadoras, lo que genera en ellos apatía y desinterés para aprender las Ciencias Sociales.

Measuring what is not seen—Transparency and good governance nonprofit indicators to overcome the limitations of accounting models

One of the most complex challenges currently faced by non-profit organizations (NPOs) is demonstrating that they manage resources with the highest levels of efficiency and excellence, and do not deviate from the accomplishment of their mission. Transparency and good governance are highly valuable issues for the survival of these organizations. However, empirical studies and models to measure these concepts are scarce and lack consensus. The objective of this article is to develop a uniform procedure for measuring the levels of transparency and good governance in NPOs, validated by experts, that integrates the most important contributions. The main proposals are supported by lists of indicators whose compliance they try to verify. Finally, we considered the experts’ preferences to obtain the indicator weights by means of the Best–Worst Method and Minimum Cost Consensus model. The result of our work is the development of a list of indicators, which integrates the existing battery of Spanish indicators. We contribute, with this work, to improving the credibility of the third sector from the perspective of donors, users, public administrations, and society. This is an essential issue for the survival of these NPOs.Universidad de Jaén, Instituto de Estudios Giennenses (Diputación de Jaén), Ministerio de Economía y Competitividad (Gobierno de España) a través del Proyecto de Investigación Nacional del Gobierno de España PGC2018-099402-B-I00 y el Contrato Postdoctoral Ramón y Cajal (RYC-2017-21978)

A Linguistic Group Best–Worst Method for Measuring Good Governance in the Third Sector: A Spanish Case Study

The need of Non-profit Organizations (NPOs) of generating trust and credibility, to their stakeholders by an efficient management of their resources, lead them to openly show that they develop adequate good governance practices. But this is not a simple task and few research has been done on measuring methods of good governance in this field; without achieving an agreement about the best procedure. This paper aims at facilitating the measurement of good governance practices in NPOs by a fuzzy linguistic consensus-based group multi-criteria decision-making (MCGDM) model that will provide agreed and easy-understanding weights for a list of indicators proposed by the stakeholders and entities in such good governance practices. To do that, a linguistic 2-tuple BWM method with a consensus reaching process (CRP) will be developed and then applied to a real-world case in Spain, in which a group of experts from significant Spanish NPOs will assess the list of indicators proposed by the most representative entities (the alliance between the non-governmental organizations (NGO) Platform for Social Action, and the NGO Coordinator for Development (CONGDE) to obtain a prioritization of such indicators for measuring the good governance practices in Spanish NPOs.Ministerio de Economía y Competitividad (Gobierno de España) a través del Proyecto de Investigación Nacional PGC2018-099402-B-I00, la Beca Posdoctoral Ramón y Cajal (RYC-2017-21978) y el proyecto FEDER-UJA 1380637 y ERDF

Evaluation of a novel microfluidic immuno-magnetic agglutination assay method for detection of dengue virus NS1 antigen

BACKGROUND: Dengue virus (DENV) is the most important arbovirus worldwide, causing infections in endemic countries and returning travellers from these areas. Rapid diagnostic tests are needed to improve patient management and monitor local transmission. The detection of DENV non-structural protein 1 (NS1) is a useful tool for the diagnosis, but the currently available methods can be time consuming or lack sensitivity. The objective of our study was to evaluate a new rapid and semi-quantitative microfluidic DENV NS1 immuno-magnetic agglutination assay based on aggregation of magnetic nanoparticles detected by an electronic reader (Virotrack Dengue Acute and Blubox, Blusense diagnostics, Copenhagen, Denmark). METHODOLOGY/PRINCIPAL FINDINGS: A panel of 135 serum samples from travelers returning from dengue endemic countries was analyzed (74 DENV positive samples including the four DENV serotypes, 26 Zika virus positive samples, 25 chikungunya virus positive samples, 5 malaria positive samples and 5 negative samples). Samples were tested by three different antigen detection methods: SD Dengue NS1 Ag ELISA, SD BIOLINE Dengue Duo and ViroTrack Dengue Acute. The sensitivity observed for SD Dengue NS1 Ag ELISA, ViroTrack Dengue Acute and SD BIOLINE Dengue Duo was 97.2%, 91.1% and 68.1%, respectively. All methods showed high specificity (98.4% for ViroTrack Dengue Acute and 100% for both SD Dengue NS1 Ag ELISA and SD BIOLINE Dengue Duo). SD Dengue NS1 Ag ELISA and ViroTrack Dengue Acute only failed to detect samples positive for DENV-2. CONCLUSIONS/SIGNIFICANCE: ViroTrack Dengue Acute is a sensitive and specific assay for DENV NS1 detection. It provides faster results than the ELISA method and a better performance than the rapid immunochromatographic tests. ViroTrack Dengue Acute could represent a valuable tool for rapid diagnosis of DENV infections in returning travellers from endemic countries

Molecular characterization of imported and autochthonous dengue in northeastern spain

Dengue is the most significant arbovirus worldwide and a public health threat to nonendemic areas in which Aedes vectors are present. Autochthonous dengue transmission has been reported in several European countries in the last decade. Infected travelers from endemic regions arriving to areas colonized by Aedes albopictus in Europe need to be monitored in surveillance and control programs. We aimed to perform molecular characterization of RT-PCR-positive dengue cases detected in Catalonia, northeastern Spain, from 2013 to 2018. The basic demographic information and the geographical regions of importation were also analyzed. One-hundred four dengue cases were studied (103 imported infections and the first autochthonous case in our region). The dengue virus strains detected were serotyped and genotyped using molecular methods, and phylogenetic analyses were conducted. All four dengue serotypes were detected in travelers, including up to 10 different genotypes, reflecting the global circulation of dengue in endemic areas. The primary travel-related case of the 2018 autochthonous transmission was not identified, but the molecular analysis revealed dengue serotype 1, genotype I of Asian origin. Our results highlight the diversity of imported dengue virus strains and the role of molecular epidemiology in supporting arbovirus surveillance programs
