Published: October 2021

A pesar de su importancia, los efectos de la retroalimentación en entornos en línea no han sido ampliamente evaluados; tampoco hay consenso sobre cómo deben medirse. El objetivo de este estudio exploratorio es analizar los efectos de la retroalimentación del profesorado durante el desarrollo de un foro de discusión en línea. Durante un período de tres semanas, los participantes (14 estudiantes universitarios y su tutor) participaron en un debate virtual sobre el uso de Wikipedia con fines académicos, utilizando la plataforma Knowledge Forum (los participantes realizaron 328 publicaciones en total). Sobre la base de las características de los entornos de aprendizaje en línea, desarrollamos un modelo multidimensional para estudiar los comentarios del profesor y sus efectos durante la interacción en línea. Los resultados muestran los principales efectos de la retroalimentación tanto en la discusión de los estudiantes sobre los temas de aprendizaje -efecto en cadena y efecto en racimo-, como en las reglas de participación en el debate. El documento concluye con una discusión sobre las implicaciones teóricas y prácticas de estos resultados.
Despite its importance, the effects of feedback in online environments has not been widely assessed; nor is there any consensus on how it should be measured. The aim of this exploratory study is to analyse the effects of teacher feedback during the development of an online discussion forum. Over a three-week period, the participants (14 university students and their tutor) engaged in a virtual debate on the use of Wikipedia for academic purposes, using the Knowledge Forum platform (participants made 328 posts in total). Based on characteristics of online learning environments, we developed a multidimensional model to study feedback and its effects during online interaction. The results show the main effects of the teacher's feedback both on the students' discussion about learning topics –chain effect and cluster effect– and on the rules of participation in the debate. The paper concludes with a discussion on the theoretical and practical implications of these results.

Los encuentros científicos en línea motivados por la Covid19 han sido una práctica muy común recientemente. No es nueva esta modalidad, pero hoy por su crecimiento solicitan soluciones tecnológicas estables y experimentadas. En un año se ha avanzado mucho en diferentes funciones en los sistemas de videoconferencias, como también en nuevas fórmulas para presentar los trabajos científicos como son los videopóster, que utilizando tecnologías emergentes de anotaciones de vídeo permiten una mayor interacción y debate en los trabajos científicos en un evento en línea. El estudio analiza la cantidad y la calidad de las anotaciones dentro de las cuales se recogen los debates e interacciones entre los autores y los oyentes de una mesa de comunicaciones con videopóster frente a otra presencial. La evaluación de la experimentación se realiza bajo estudio descriptivo de datos cuantitativos y cualitativos, y técnicas de análisis de contenidos “Q-análisis” de las 437 anotaciones y las 238 intervenciones en los 16 videopóster de un evento en línea. Los resultados muestran el doble de participación en la modalidad de videopóster frente a las Comunicaciones presenciales, al tiempo que se enumera un número relevante de beneficios que ofrecen los videopóster para el desarrollo de eventos en línea y redes profesionales de aprendizaje.
Online scientific meetings motivated by Covid19 have been a very common practice recently. This modality is not new, but today, due to its growth, it requires stable and experienced technological solutions. In one year, much progress has been made in different functions in videoconferencing systems, as well as in new formulas for presenting scientific papers, such as videoposters, which, using emerging video annotation technologies, allow greater interaction and discussion of scientific papers in an online event. The study analyzes the quantity and quality generated by discussions between authors and listeners at a videoposter presentation table versus a face-to-face one. The evaluation of the experiment is performed under a descriptive study of quantitative and qualitative data, and content analysis techniques "Q-analysis" of the 450 annotations and 355 interventions in the 16 videoposters of an online event. We found twice the production of participation in the video-poster modality compared to face-to-face communications, while listing a relevant number of benefits offered by videoposters for the development of online events and professional learning networks.

Published: October 2021

El éxito del proceso educativo mediados por la tecnología, depende en gran medida de la adopción y el uso de la tecnología digital (TD) por parte del profesorado, desde esta corriente se presenta un diagnóstico multivariado sobre el nivel de adopción y uso de las TD, mediante el efecto moderador de las variables género y edad, el estudio se llevó a cabo con una muestra de 280 docentes universitarios que respondieron el cuestionario denominado TAUT conformado por 46 ítems tipo escala de Likert en 5 dimensiones. La metodología aplicada en el estudio es cuantitativa basada en el método no experimental, descriptivo e inferencial, los datos fueron analizados a partir de una comparación de medias, utilizando pruebas no paramétricas. Los resultados se manifiestan por medio del TAUT autoevaluando la adopción y uso de las TD por parte del profesorado, los mismos que logran poseer una aceptación positiva en todas las dimensiones, como también permiten conocer que no existen diferencias significativas en la mayoría de los ítems en función del género como la edad, los mismos que no afectan a la intención del comportamiento del profesorado para adoptar y usar las TD.

The methodology applied in the study is quantitative based on the non-experimental, descriptive and inferential method, the data were analyzed from a comparison of means, using non-parametric tests. The results are shown by means of the TAUT self-evaluating the adoption and use of the TD by the teaching staff, the same that manage to have a positive acceptance in all the dimensions, as well as allowing to know that there are no significant differences in most of the items according to gender and age, the same that do not affect the intention of the teaching staff behavior to adopt and use the TD.
Creating a map of Arctic Indigenous languages and revitalization
Authors: Nordström Linnea 
Published: October 2021

In 2019 the University Library at UiT - The Arctic University of Norway partnered with the Arctic Council Indigenous Peoples' Secretariat to create Ságastallamin - Telling the Story of Arctic Indigenous Languages, an interactive multi-media exhibition commemorating the UN International Year of Indigenous Languages.
An Arctic Indigenous language map was updated for use in the exhibition, but the print format proved to be limiting, and the exhibition time frame did not allow for a thorough linguistic review. Therefore a follow-up project “Arctic Indigenous languages and revitalization: an online educational resource” was started in 2021 to further develop the map and convert it to an openly available online educational resource in GIS format. One key aspect of the new map is that it will feature individual language names in their Indigenous names, as well as in English and Russian.
The project team consists of representatives from Higher Educational Institutions, Indigenous organizations, and Government departments from Canada, Finland, Greenland, Norway, Russia and the United States. The work on the map has just begun and this spring and summer the goal is to collect feedback from Indigenous language experts on the original exhibition print map before designing a new GIS version in the fall.
We would like to present the current print map to the Arctic Knot conference in order to receive feedback about additional languages to include, creative ways to present language information in different layers, and suggestions for innovative language revitalization initiatives to feature on the map. There is an online form to collect feedback, and so the lightning talk would be used to present the project goals briefly and then encourage conference participants to submit feedback using the form after the talk.

Published: October 2021

Background
Sugarcane (Saccharum spontaneum L.), the major sugar and biofuel feedstock crop, is cultivated mainly by vegetative propagation worldwide due to the infertility of female reproductive organs resulting in the reduction of quality and output of sugar. Deciphering the gene expression profile during ovule development will improve our understanding of the complications underlying sexual reproduction in sugarcane. Optimal reference genes are essential for elucidating the expression pattern of a given gene by quantitative real-time PCR (qRT-PCR).

Method
In this study, based on transcriptome data obtained from sugarcane ovule, eighteen candidate reference genes were identified, cloned, and their expression levels were evaluated across five developmental stages ovule (AC, MMC, Meiosis, Mitosis, and Mature).

Results
Our results indicated that FAB2 and MOR1 were the most stably expressed genes during sugarcane female gametophyte development. Moreover, two genes, cell cycle-related genes REC8 and CDK, were selected, and their feasibility was validated. This study provides important insights into the female gametophyte development of sugarcane and reports novel reference genes for gene expression research on sugarcane sexual reproduction.
Vocal communication in wild chimpanzees: a call rate study
Authors: Crunchant Anne-Sophie , Stewart Fiona A. , Piel Alex K. 
Published: October 2021

Background
Patterns of vocal communication have implications for species conservation: a change in calling behaviour can, for instance, reflect a disturbed habitat. More importantly, call rate is a parameter that allows conservation planners to convert call density into animal density, when detecting calls with a passive acoustic monitoring system (PAM).

Methods
We investigated chimpanzee (Pan troglodytes schweinfurthii) call rate during the late dry season in the Issa Valley, western Tanzania by conducting focal follows. We examined the socio-ecological factors that influence call production rate of savanna woodland chimpanzees.

Results
We found that sex, proportion of time spent in a vegetation type, proportion of time spent travelling, time of the day, party size and swollen parous female presence had a significant effect on the call rate. Call rate differed among the different demographic classes with subadult and adult males vocalising twice as often as the subadult and adult females and three times as often as the juveniles.

Applications
The use of PAM and recent statistical developments to estimate animal density is promising but relies on our knowing individual call rate, often not available for many species. With the improvement in automatic call detection, we anticipate that PAM will increasingly be broadly applied to primates but also across taxa, for conservation.

Objectives: Bauchi is one of the 36 states in Nigeria, the seventh most populous country in the world. This area has the second highest prevalence of thinness among women; with unacceptably high proportions of children 0 – 5 years being stunted. Household dietary intake is believed to be an underlying factor for this nutrition situation. Determination of the nutritional composition of traditional foods is essential in order to evaluate the dietary drivers of undernutrition, and to design interventions to promote sustainable, healthy diets. Yet data on the nutritional composition of traditional foods are lacking. Thus, this study measured the proximate and mineral composition of 31 traditional, composite foods consumed in Bauchi State, Nigeria.
Methods: Proximate analyses and assays for iron (Fe), zinc (Zn), copper (Cu), and calcium (Ca) were conducted according to methods stipulated by AOAC International.
Results: The protein content (9.12%) of dambun tsakin masara da alaiho (maize grits and spinach) and the Ca, Fe and Cu concentrations (89.64 mg, 6.01 mg and 0.31 mg per 100 g, respectively) of dambun gero da zogale (millet and Moringa) were the greatest among granulated dumplings. Danwake wake da dawa (cowpea and sorghum) had the greatest protein composition (4.78%) while danwaken gujiya da masara (Bambara nut and maize) had the highest Fe, Zn and Cu concentrations (3.97 mg, 1.20 mg and 0.28 mg, respectively) per 100 g of cooked dough balls. Miyan karago (powdered peanut cake soup) had the greatest protein concentration (11.40 %) per 100 g of soup. Among cereal paps, puddings and porridges, Chanchangan dawa (sorghum, peanut and beans porridge) had the highest protein content (6.43%). Of all foods analyzed, dambun naman rago (shredded, fried mutton) and awara (spicy, fried tofu) were richest in protein (49.31% and 16.86%) and iron (9.20 and 8.32 mg/100g), respectively.
Conclusion: Traditional foods with good nutrition profiles are available to support adequate nutrition of women and children in rural households in Bauchi State, despite widespread undernutrition.

Published: October 2021

The present study was conducted at Kadapa district of Andhra Pradesh with the objectives to find out the relationship between the turmeric farmers’ profile and their marketing behaviour. Ex post facto research design was used for the study. Two mandals of Kadapa district namely Mydukur and Duvvur were purposively selected based on the highest area under turmeric cultivation and data was collected from a randomly drawn sample of 90 respondents by a structured questionnaire administered personally as per schedules. The correlation results of the study revealed that the independent variables viz., age, farming experience, education, material possession, extension contact, training received, achievement motivation and social interaction had positive and statistically significant relationship with the marketing behaviour of the turmeric farmers. Whereas, area under turmeric cultivation and economic status had non-significant relationship with the marketing behaviour of the turmeric farmers. Multiple Linear Regression analysis revealed that all the selected 10 independent variables put together explained about 79.10 per cent variation in the marketing behaviour of turmeric farmers. The analysis of turmeric farmers’ profile indicated that majority of them were middle aged, with less than 2.5 acres of area under turmeric cultivation with medium farming experience, high school level of education, medium economic status, extension contact, training received, achievement motivation and social interaction and they also had medium level of marketing behaviour due to medium levels of planning orientation, production orientation, marketing orientation, market information sources utilization, decision making ability, risk taking ability and innovativeness.

Aims: The genomic and non-genomic actions of human estrogen receptor α (hERα) play a crucial role in breast epithelial cell proliferation and survival, as well as mammary tumorigenesis. hERα has been proved as a potential target for breast cancer therapy over the last 3 decades. Hence designing novel inhibitors targeting hERα can be a valuable approach in breast cancer therapy.
Study Design: In the present study, the goal is to identify novel hERα inhibitors through molecular docking, AI based virtual screening and interaction fingerprint analysis.
Place and Duration of Study: Department of Bioinformatics, Sri Venkateswara Institute of Medical Sciences, Tirupati, Andhra Pradesh, India in between July 2021-sep 2021.
Methodology: Molecular docking studies were performed using the human estrogen receptor alpha ligand-binding domain in complex with 4-hydroxytamoxifen (PDB: 3ERT) against existing compounds from literature. The best docked existing compound and co-crystal ligand were subjected to shape screening against 28 million compounds and resulted compounds constituted the hERα inhibitor dataset which was subjected to rigid receptor docking. Further, interaction fingerprint analysis was applied as complimentary method to docking for comparing the similarity of predicted binding poses of proposed leads with that of reference binding pose.
Results: Co-crystal ligand (4-OHT) and E99 exhibited better binding affinity among existing ligand set. Rigid receptor docking studies resulted in four lead compounds possessing better docking scores than 4-OHT and E99. Moreover, leads showed favorable absorption, distribution, metabolism, excretion and toxicity properties within the range of 95% FDA approved drugs. Proposed leads showed interactions with binding site residues of hERα similar to that of 4-OHT with better binding affinity. The ability of obtained leads to retrieve actives was validated using receiver operative characteristic (ROC) curve.
Conclusion: From above results, it has been observed that the proposed leads have potential to act as novel hERα inhibitors.

AbstractThe development of effective vaccines that can be rapidly manufactured and distributed worldwide is necessary to mitigate the devastating health and economic impacts of pandemics like COVID‐19. The receptor‐binding domain (RBD) of the SARS‐CoV‐2 spike protein, which mediates host cell entry of the virus, is an appealing antigen for subunit vaccines because it is efficient to manufacture, highly stable, and a target for neutralizing antibodies. Unfortunately, RBD is poorly immunogenic. While most subunit vaccines are commonly formulated with adjuvants to enhance their immunogenicity, clinically‐relevant adjuvants Alum, AddaVax, and CpG/Alum are found unable to elicit neutralizing responses following a prime‐boost immunization. Here, it has been shown that sustained delivery of an RBD subunit vaccine comprising CpG/Alum adjuvant in an injectable polymer‐nanoparticle (PNP) hydrogel elicited potent anti‐RBD and anti‐spike antibody titers, providing broader protection against SARS‐CoV‐2 variants of concern compared to bolus administration of the same vaccine and vaccines comprising other clinically‐relevant adjuvant systems. Notably, a SARS‐CoV‐2 spike‐pseudotyped lentivirus neutralization assay revealed that hydrogel‐based vaccines elicited potent neutralizing responses when bolus vaccines did not. Together, these results suggest that slow delivery of RBD subunit vaccines with PNP hydrogels can significantly enhance the immunogenicity of RBD and induce neutralizing humoral immunity.
The quality of health and wellness self‐tracking data: A consumer perspective
Authors: Zhang Yan , Trace Ciaran B. 
Published: October 2021

AbstractInformation quality (IQ) is key to users' satisfaction with information systems. Understanding what IQ means to users can effectively inform system improvement. Existing inquiries into self‐tracking data quality primarily focus on accuracy. Interviewing 20 consumers who had self‐tracked health indicators for at least 6 months, we identified eight dimensions that consumers apply to evaluate self‐tracking data quality: value‐added, accuracy, completeness, accessibility, ease of understanding, trustworthiness, aesthetics, and invasiveness. These dimensions fell into four categories—intrinsic, contextual, representational, and accessibility—suggesting that consumers judge self‐tracking data quality not only based on the data's inherent quality but also considering tasks at hand, the clarity of data representation, and data accessibility. We also found that consumers' self‐tracking data quality judgments are shaped primarily by their goals or motivations, subjective experience with tracked activities, mental models of how systems work, self‐tracking tools' reputation, cost, and design, and domain knowledge and intuition, but less by more objective criteria such as scientific research results, validated devices, or consultation with experts. Future studies should develop and validate a scale for measuring consumers' perceptions of self‐tracking data quality and commit efforts to develop technologies and training materials to enhance consumers' ability to evaluate data quality.

AbstractTruly, kinematics in the Solar neighborhood has provided important information both for the structure and for the evolution of the Galaxy since the early 20th century. The relationship between Oort constants and the ratio of the velocity dispersion are important quantities in stellar kinematics. In the present paper, we calculated the kinematical parameters and the Oort constants of various samples of late to intermediate M‐type stars. We calculated the velocity dispersion in units of km s−1 for the samples under study. The longitude of the vertex having negative values with our analysis; that is, the program I (538 stars), ; program II (100 stars), and program III (60 stars), . We calculate the Oort constants as km s−1 kpc−1 and km s−‐1 kpc−1, and the rotational velocity . A possible explanation for the overestimated values of the second Oort constants has been presented.
