Published: May 2020

BACKGROUND

Digital health innovations can improve health system performance, yet previous experience has shown that many innovations do not advance beyond the pilot stage to achieve scale. Vietnam’s National Immunization Information System (NIIS) began as a series of digital health pilots, first initiated in 2010, and was officially launched nationwide in 2017. The NIIS is one of the few examples of an electronic immunization registry (EIR) at national scale in low- and middle-income countries.

OBJECTIVE

The aim of this study was to understand the determinants of scale-up of the national EIR in Vietnam.

METHODS

This qualitative study explored the facilitators and barriers to national scale-up of the EIR in Vietnam. Qualitative data were collected from October to December 2019 through in-depth key informant interviews and desk review. The mHealth Assessment and Planning for Scale (MAPS) Toolkit guided the development of the study design, interview guides, and analytic framework. MAPS defines the key determinants of success, or the “axes of scale,” to be groundwork, partnerships, financial health, technology and architecture, operations, and monitoring and evaluation.

RESULTS

The partnership and operations axes were critical to the successful scale-up of the EIR in Vietnam, while the groundwork and monitoring and the evaluation axes were considered to be strong contributors in the success of all the other axes. The partnership model leveraged complementary strengths of the technical working group partners: the Ministry of Health General Department of Preventive Medicine, the National Expanded Program on Immunization, Viettel (the mobile network operator), and PATH. The operational approach to introducing the NIIS with lean, iterative, and integrated training and supervision was also a key facilitator to successful scale-up. The financial health, technology and architecture, and operations axes were identified as barriers to successful deployment and scale-up. Key barriers to scale-up included insufficient estimates of operational costs, unanticipated volume of data storage and transmission, lack of a national ID to support interoperability, and operational challenges among end users. Overall, the multiple phases of EIR deployment and scale-up from 2010 to 2017 allowed for continuous learning and improvement that strengthened all the axes and contributed to successful scale-up.

CONCLUSIONS

The results highlight the importance of the measured, iterative approach that was taken to gradually expand a series of small pilots to nationwide scale. The findings from this study can be used to inform other countries considering, introducing, or in the process of scaling an EIR or other digital health innovations.
Alternative and Augmentative Communication Technologies for Supporting Adults With Mild Intellectual Disabilities During Clinical Consultations: Scoping Review (Preprint)
Authors: Gibson Ryan Colin , Bouamrane Matt-Mouley , Dunlop Mark D
Published: May 2020

BACKGROUND

People with intellectual disabilities (IDs) face significant communication barriers when accessing health care services; they find it difficult to identify and describe conditions clearly enough to support practitioners in making an accurate diagnosis. In addition, medical professionals generally have little knowledge and understanding of the needs of people with ID, which may result in the use of consultation techniques that do not cater to their patients’ skills.

OBJECTIVE

This review aims to identify and synthesize the literature on alternative and augmentative communication technologies that are used to support adults with mild ID during the exchange of information with medical practitioners.

METHODS

We performed a scoping review of studies published in English that describe the technologies that are used to promote communication with patients with mild ID during medical consultations. The databases searched were PubMed, ACM Digital Library, and Google Scholar. A qualitative framework-based approach was used to synthesize the data and discern key recurring themes across the identified literature.

RESULTS

Of the 1557 articles screened, 15 (0.96%) met our inclusion criteria. The bulk of the communication aids used focused on low-tech solutions, including patient passports, note-based prompts, Talking Mats, health diaries, and easy-read information sheets. Their influence on current practice ranged from advancing medical professionals’ knowledge of the health and communication needs of people with ID to increasing interagency collaboration, patient advocacy skills, and health promotion activities. The major barriers to the implementation of low-tech aids were a lack of portability and increased maintenance efforts. Only 3 studies explored the use of mobile apps to promote communication. Their findings indicated that high-tech solutions offer greater customization with regard to the accessibility and health care needs of people with ID.

CONCLUSIONS

Alternative and augmentative communication technologies have the potential to increase the quality of care provided to patients with mild ID; however, little work has been carried out in this area. Greater emphasis must be placed on (high-tech) two-way communication aids that empower patients to become involved in decisions regarding their care. Quantitative evaluation methods should be used to discern the true benefits of such aids, and researchers should describe their study protocols in depth to promote replication and generalizability.
Coaching While Waiting for Autism Spectrum Disorder Assessment: Protocol of a Pilot Feasibility Study for a Randomized Controlled Trial on Occupational Performance Coaching and Service Navigation Support (Preprint)
Authors: Bernie Charmaine , Williams Katrina , Graham Fiona , May Tamara
Published: May 2020

BACKGROUND

In Australia, the average time between a first concern of autism spectrum disorder (ASD) and diagnosis is over 2 years. After referral for assessment, families often wait 6-12 months before their appointment. This can be a time of uncertainty and stress for families. For some families, other forms of assistance are not accessible and thus timely intervention opportunities are missed. There is little evidence about how to provide the best support for children or caregivers while on assessment waiting lists.

OBJECTIVE

The aim of this study is to determine whether use of a coaching intervention called Occupational Performance Coaching (OPC) combined with service navigation support is feasible for families waiting for ASD assessment, as a crucial first step in planning a randomized controlled trial.

METHODS

A pilot and feasibility study will be conducted using recommended constructs and associated measures, which will be reported using CONSORT (Consolidated Standards or Reporting Trials) guidance. Participants will be child and caregiver dyads or triads, recruited within 4 months of their child (aged 1-7 years) being referred to one of two services for an ASD assessment in Victoria, Australia. A blinded randomization procedure will be used to allocate participants to one of three trial arms: (1) coaching and support intervention delivered face to face, (2) coaching and support intervention via videoconference, and (3) usual care. Descriptive statistics will be used to describe the sample characteristics of parents and children, inclusive of service access at baseline and follow up. Recruitment rates will be reported, and retention rates will be evaluated against a predicted rate of 70%-80% in each intervention arm. Goal attainment, using the Canadian Occupational Performance Measure, will indicate preliminary evidence for efficacy within the intervention arms, with an increase of 2 or more points on a 10-point performance and satisfaction scale considered clinically significant.

RESULTS

The study was approved by The Royal Children’s Hospital Research Ethics and Governance Department in September 2018. As of October 2020, 16 families have been recruited to the study. Data analysis is ongoing and results are expected to be published in 2021.

CONCLUSIONS

Study findings will support planning for a future randomized controlled trial to assess the efficacy of OPC and service navigation support for caregivers of children awaiting ASD assessment.

Internet-Specific Epistemic Beliefs in Medicine and Intention to Use Evidence-Based Online Medical Databases Among Health Care Professionals: Cross-sectional Survey (Preprint)
Authors: Chiu Yen-Lin , Lee Yu-Chen , Tsai Chin-Chung
Published: May 2020

BACKGROUND

Evidence-based medicine has been regarded as a prerequisite for ensuring health care quality. The increase in health care professionals’ adoption of web-based medical information and the lack of awareness of alternative access to evidence-based online resources suggest the need for an investigation of their information-searching behaviors of using evidence-based online medical databases.

OBJECTIVE

The main purposes of this study were to (1) modify and validate the internet-specific epistemic beliefs in medicine (ISEBM) questionnaire and (2) explore the associations between health care professionals’ demographics, ISEBM, and intention to use evidence-based online medical databases for clinical practice.

METHODS

Health care professionals in a university-affiliated teaching hospital were surveyed using the ISEBM questionnaire. The partial least squares-structural equation modeling was conducted to analyze the reliability and validity of ISEBM. Furthermore, the structural model was analyzed to examine the possible linkages between health professionals’ demographics, ISEBM, and intention to utilize the evidence-based online medical databases for clinical practice.

RESULTS

A total of 273 health care professionals with clinical working experience were surveyed. The results of the measurement model analysis indicated that all items had significant loadings ranging from 0.71 to 0.92 with satisfactory composite reliability values ranging from 0.87 to 0.94 and average variance explained values ranging from 0.70 to 0.84. The results of the structural relationship analysis revealed that the source of internet-based medical knowledge (path coefficient –0.26, P=.01) and justification of internet-based knowing in medicine (path coefficient 0.21, P=.001) were correlated with the intention to use evidence-based online medical databases. However, certainty and simplicity of internet-based medical knowledge were not. In addition, gender (path coefficient 0.12, P=.04) and academic degree (path coefficient 0.15, P=.004) were associated with intention to use evidence-based online medical databases for clinical practice.

CONCLUSIONS

Advancing health care professionals’ ISEBM regarding source and justification may encourage them to retrieve valid medical information through evidence-based medical databases. Moreover, providing support for specific health care professionals (ie, females, without a master’s degree) may promote their intention to use certain databases for clinical practice.
Barriers to and facilitators for using nutrition apps: a scoping review and conceptual framework (Preprint)
Authors: König Laura Maria , Attig Christiane , Franke Thomas , Renner Britta
Published: May 2020

BACKGROUND

Nutrition apps are a prototypical mobile health (mHealth) technology supporting healthy eating behavior that are seen as promising tools for health promotion by policy makers. Although nutrition apps are increasingly popular, wide-spread adoption is yet to be achieved. Hence, profound knowledge regarding factors motivating and hindering (long-term) nutrition app use is crucial for developing design guidelines aiming at supporting uptake and prolonged use of nutrition apps.

OBJECTIVE

In this scoping review, we synthesized the literature on barriers to and facilitators for nutrition app use across disciplines including empirical qualitative and quantitative studies with current users, ex-users, and/or non-users of nutrition apps.

METHODS

A systematic literature search including six databases as well as backward and forward citation search was conducted. Search strategy, inclusion and exclusion criteria, and the planned data extraction process were preregistered. All empirical qualitative and quantitative studies published in German or English were eligible for inclusion if they examined adults or adolescents (aged 13 to 18) who were either current users, ex-users and/ or non-users of nutrition apps. Based on qualitative content analysis, extracted individual barriers and facilitators were grouped into categories.

RESULTS

Twenty-eight publications were identified as eligible. A framework with a three-level hierarchy was designed which grouped 326 individual barriers and facilitators into 21 sub-categories, twelve categories, and four clusters that focus on either the individual user (goals, goal attainment, goal abandonment, personal living conditions, lack of knowledge or skill, lack or loss of motivation, habit), different aspects of the app and the smartphone (features, usability of the app or food database, technical issues, data security, accuracy/trustworthiness, costs), positive and negative outcomes of nutrition app use, or interactions between the user and their social environment.

CONCLUSIONS

The resulting conceptual framework underlines a pronounced diversity of reasons for (not) using nutrition apps indicating that there is no “one-size-fits-all” approach for uptake and prolonged use of nutrition aps. Hence, tailoring nutrition apps to needs of specific user groups seems promising for increasing engagement.

Authors: Halalau Alexandra , Ditkoff Jeffrey , Hamilton Jessica , Sharrak Aryana , Vanood Aimen , Abbas Amr , Ziadeh James
Published: May 2020

BACKGROUND

Coronavirus disease (COVID-19) is a global pandemic that has placed a significant burden on health care systems in the United States. Michigan has been one of the top states affected by COVID-19.

OBJECTIVE

We describe the emergency center curbside testing procedure implemented at Beaumont Hospital, a large hospital in Royal Oak, MI, and aim to evaluate its safety and efficiency.

METHODS

Anticipating a surge in patients requiring testing, Beaumont Health implemented curbside testing, operated by a multidisciplinary team of health care workers, including physicians, advanced practice providers, residents, nurses, technicians, and registration staff. We report on the following outcomes over a period of 26 days (March 12, 2020, to April 6, 2020): time to medical decision, time spent documenting electronic medical records, overall screening time, and emergency center return evaluations.

RESULTS

In total, 2782 patients received curbside services. A nasopharyngeal swab was performed on 1176 patients (41%), out of whom 348 (29.6%) tested positive. The median time for the entire process (from registration to discharge) was 28 minutes (IQR 17-44). The median time to final medical decision was 15 minutes (IQR 8-27). The median time from medical decision to discharge was 9 minutes (IQR 5-16). Only 257 patients (9.2%) returned to the emergency center for an evaluation within 7 or more days, of whom 64 were admitted to the hospital, 11 remained admitted, and 4 expired.

CONCLUSIONS

Our curbside testing model encourages the incorporation of this model at other high-volume facilities during an infectious disease pandemic.
Improving Diagnostic Classification of Stillbirths and Neonatal Deaths Using ICD-PM (International Classification of Diseases for Perinatal Mortality) Codes: Validation Study (Preprint)
Authors: Luk Hiu Mei , Allanson Emma , Ming Wai-Kit , Leung Wing Cheong
Published: May 2020

BACKGROUND

Stillbirths and neonatal deaths have long been imperfectly classified and recorded worldwide. In Hong Kong, the current code system is deficient (>90% cases with unknown causes) in providing the diagnoses of perinatal mortality cases.

OBJECTIVE

The objective of this study was to apply the International Classification of Diseases for Perinatal Mortality (ICD-PM) system to existing perinatal death data. Further, the aim was to assess whether there was any change in the classifications of perinatal deaths compared with the existing classification system and identify any areas in which future interventions can be made.

METHODS

We applied the ICD-PM (with International Statistical Classification of Diseases and Related Health Problems, 10th Revision) code system to existing perinatal death data in Kwong Wah Hospital, Hong Kong, to improve diagnostic classification. The study included stillbirths (after 24 weeks gestation) and neonatal deaths (from birth to 28 days). The retrospective data (5 years) from May 1, 2012, to April 30, 2017, were recoded by the principal investigator (HML) applying the ICD-PM, then validated by an overseas expert (EA) after she reviewed the detailed case summaries. The prospective application of ICD-PM from May 1, 2017, to April 30, 2019, was performed during the monthly multidisciplinary perinatal meetings and then also validated by EA for agreement.

RESULTS

We analyzed the data of 34,920 deliveries, and 119 cases were included for analysis (92 stillbirths and 27 neonatal deaths). The overall agreement with EA of our codes using the ICD-PM was 93.2% (111/119); 92% (78/85) for the 5 years of retrospective codes and 97% (33/34) for the 2 years of prospective codes (P=.44). After the application of the ICD-PM, the overall proportion of unknown causes of perinatal mortality dropped from 34.5% (41/119) to 10.1% (12/119) of cases (P<.001).

CONCLUSIONS

Using the ICD-PM would lead to a better classification of perinatal deaths, reduce the proportion of unknown diagnoses, and clearly link the maternal conditions with these perinatal deaths.
A call to action for healthcare organizations to harness social media to counter the anti-vaccination movement. (Preprint)
Authors: Kay Tatjana
Published: May 2020

UNSTRUCTURED

Vaccines have greatly reduced, if not eliminated many devastating diseases. But the number of proponents of the anti-vaccination movement has been growing as ‘anti-vaxxers’ use social media to disseminate misinformation leading to more people choosing not to vaccinate their children or receive vaccines themselves. This has resulted in a lowering of herd immunity and outbreaks around the world. Healthcare organizations need to harness social media to spread accurate information and counter misinformation. Healthcare organizations are reputable sources that can address misinformation, educate the public, accurately explain science and research, and counter misinformation. But they need to be easily accessible and readily involved in online vaccination discussions. Social media serves the anti-vaccination movement by providing several channels to reach audiences; and facilitates the dissemination of a variety of content through both different platforms and different features within a given site. It is crucial for healthcare organizations to use social media in order to (1) have early influence on users, (2) increase direct engagement with users, and (3) counter anti-vaxx claims. How healthcare organizations can harness social media is explained in terms of (1) the content that is posted and where it is posted, (2) passive monitoring of social media.
Spanish Heritage Language Learners: A Review of Literature Analyzing Their Preference of the English Language
Authors: Guillen-Ramos Hilda , Huber Tonya
Published: May 2020

The increased number of Spanish Heritage Language (SHL) speakers in American schools has called for the need of new research focused on SHL students, their parents, their teachers, and a profound analysis of best instructional practices for this individualized group of students. The purpose of this thorough analysis of peer-reviewed literature is to evaluate language programs for the growing SHL student population in elementary schools. A careful look into this growing population will help evaluate the educational programs provided to SHL students such as the Dual Language (DL) immersion program and the Transitional Bilingual Education program (TBE). This review addresses why students walk into an elementary classroom as an SHL and English language bilingual and subsequently become monolinguals as they progress in their elementary school years. Recognizing the factors that lead to a student’s language preference can assist parents, teachers, and the education system in developing an academic structure that will promote bilingualism and biliteracy for SHL learners.

Análisis multi-criterio sobre barreras biogeográficas para la movilidad humana en Patagonia meridional
Authors: Pallo María Cecilia , Borrero Luis A.
Published: May 2020

Much of the discussion on the human biogeography of the lake system south of Lago Argentino (southern Patagonia) has been focused on the “dead ends”, near the Andean lakes, its link with continental ice as an important barrier to human movement, and the Baguales Range immediately to the east. Other minor barriers were discussed recently. Among the latter, here we add the plateaus, their edges and the small fluvial valleys at the foot of the plateaus locally called ensenadas or "inlets". The methodology includes a least-cost pathways analysis based on multi-criteria cost surfaces, a hierarchical spatial model based on landscape resistance to human circulation, the use of GIS (Geographic Information Systems) tools and remote sensing techniques on satellite images. A scheme of priority and alternative pathways is derived, whose availability and potential spatial disconnections at times of snowfall, reinforce the logistical exploitation of the area. Thus, the key to the intensity of human occupation in this sector has very likely been linked to the increase or decrease of costs movements, also articulated with land-use strategies centered on other ecologically complementary spaces.
Desde una educación intercultural para pueblos indígenas hacia otra pertinente al contexto migratorio actual. Un análisis basado en el caso de Chile
Authors: Riedemann Andrea , Stefoni Carolina , Stang Fernanda , Corvalán Javier
Published: May 2020

This article poses the question if the Intercultural Bilingual Education Programa of Chile (PEIB, for its name in spanish), the education policy designed for those groups that historically have been considered as representatives of cultural diversity –those groups recognized by the chilean Indigenous Law- is suitable for the rather new context that has emerged in schools due to international migration. The analysis presents the origin of PEIB and the context that made it possible, focuses on two central features of the PEIB, and then discusses the possible connection points with the new context. Based on a document analysis of the aforementioned aspects and some of the evaluations the program has gone through, we conclude that it is rather not recommendable to use the PEIB as a starting point for a education policy that attends to the migration context. At this point, the article presents some thoughts about the challenges the chilean education system -deeply rooted in a neoliberal society model- faces to advance towards a good education system for all, that also takes into account cultural diversity.

Análisis de las emociones sociomorales y el acoso escolar entre pares en República Dominicana
Authors: Noboa-Lanfranco Joan , Santana-Guzmán Maffel
Published: May 2020

Esta investigación tuvo como objetivo identificar las emociones sociomorales y percepciones del acoso escolar entre estudiantes. Se trabajó con un método no experimental, de tipo transversal con enfoque cuantitativo y alcance descriptivo. Participaron del estudio 15 estudiantes de 6to, 7mo y 8vo grado de edades entre 11 y 16 años; seleccionados a través de un muestreo no probabilístico. Se utilizó el instrumento SCAN-Bullying creado por Almeida, Del Barrio, Marqués, Gutiérrez y Van Der Meulen, (2001). El estudio determinó que las emociones varían dependiendo del rol en la dinámica de acoso. Las víctimas son percibidas como tristes y solas, aunque humildes y bondadosas. No obstante, los agresores son percibidos como indiferentes y orgullosos, pero extrovertidos y fuertes. También se encontró que el estudiantado justifica el acoso escolar considerándolo una forma de diversión.

El propósito de este estudio es describir las perspectivas que posee el estudiantado ingresante a la carrera de Psicología de una universidad argentina de gestión estatal, acerca de la lectura en la escolaridad secundaria y en contextos académicos. Se entrevista a 27 estudiantes del primer año de la mencionada carrera y se analizan estas entrevistas en función de categorías emergentes y que se desprenden del marco teórico. Los resultados muestran que los estudiantes con rendimiento académico alto perciben continuidades entre las prácticas lectoras del secundario y las de la universidad, y los que tienen un rendimiento bajo, diferencias sustantivas entre las mismas. Las continuidades y las diferencias se relacionan con las clases de textos y con las prácticas pedagógicas docentes. Estos hallazgos permiten entrever las diferencias derivadas de la escolaridad de base y la necesidad de abordar en las aulas universitarias la enseñanza de la lectura disciplinar en cada asignatura.
Oligosaccharides as Green Catalyst for One-Pot Multicomponent Synthesis of Spirooxindole Derivatives in Water
Authors: Anand Mohan Jha  , Nidhi Jha
Published: May 2020

A one pot synthetic methodology has been developed towards multicomponent synthesis of spiro[indoline-3,2'- quinazoline]-2,4'(3'H)-dione from isatoic anhydride, isatin and primary amines in aqueous medium via supramolecular catalysis. An untapped potential of β-Cyclodextrin to mediate multicomponent reactions in aqueous medium has been revealed. Developed protocol was further verified by extrapolating the synthetic protocol using different isatin derivatives and amine analogues. In other synthetic scheme, some compounds were synthesized by reaction of various substituted benzaldehydes, Isatoic anhydride and  primary  amines.  Synthesized  library  of  compounds  were  further  characterized  using  various  spectroscopic  techniques. During all the synthetic process,  the  catalytic efficiency  of cyclodextrin  was  exploited. Efficiency of  all the three forms  of cyclodextrins were tested to find the best reaction for synthesis of spiro compounds. The usefulness of β-cyclodextrin was proved by showing its reusability. The essential role of β-cyclodextrin in the synthetic methodology is further proved by doing the control experiments which showed that no product was formed in the absence of catalyst. The attachment of reactant molecule was also proved by doing 1H NMR of reaction mixture at different time interval in D2O. On the basis of observation, a plausible mechanistic pathway of reaction was proposed. Other two forms of cyclodextrins were also eliminated on the ground of their insuitability in the formation of desired product. Catalyst reusability was studied and it was shown that our catalytic system is useful without any significant loss in catalytic potential even after 5 cycles. Catalyst recovery procedure was established and was used without any significant loss of catalytic activity upto 5 times.

Published: May 2020

ABSTRACT Energi listrik memegang peranan yang sangat dominan dalam kehidupan masyarakat sehari-hari, sehingga jika terjadi pemadaman listrik akan menimbulkan kerugian.  Guna mengurangi pemadaman maka diperlukan back up sumber tegangan untuk mensupply beban.  Back up sumber tegangan dipasang parallel yang bekerja secara bergantian otomatis sebelum sebelum masuk ke beban yang disebut System Spot Network.  System parallel dua sumber tegangan menggunkan suatu kubikel tegangan menengah yang disebut Automatic Change Over.  Untuk mengetahui keandalan sebelum dan sesudah dipasang ACO maka ditetapkan suatu indeks keandalan yaitu SAIDI (System Average Interruption Duration Index) dan SAIFI (System Average Interruption Frequency Index). Setelah dipasang ACO tidak pernah mengalami pemadaman sehingga nilai perhitungan indeks SAIFI realisasi di lapangan sebelumnya adalah 0,05 pemadaman/tahun menjadi Nol.  Begitu pula dengan perhitungan SAIDI realisasi di lapangan sebelumnya adalah 0,112 jam/tahun menjadi Nol

SISTEM MONITORING SKENARIO TESTING PADA SISTEM IFINANCING STUDY KASUS PT. IMS
Authors: Wibowo Amirudin
Published: May 2020

Berkembangnya teknologi membuat perusahaan membutuhkan aplikasi untuk membantu bisnis yang dijalankan. Meningkatnya kebutuhan tersebut membuat munculnya konsultan IT yang menawarkan jasa mereka untuk mengembangkan sistem di perusahaan yang membutuhkan sistem. Dalam pengembangan suatu sistem tentu saja harus dilakukan pengujian untuk memastikan sistem yang dibuat sudah sesuai dengan proses yang berjalan saat ini. Pengujian sistem dilakukan untuk mengetahui kualitas sistem yang nantinya akan digunakan oleh penggunanya. Setiap sistem yang diimplementasikan di perusahaan tertentu memiliki perbedaan cara pengujian sehingga dibuatlah skenario testing untuk melakukan pengujian tersebut. Skenario testing ini tentu saja untuk melihat apakah sistem yang dibuat sudah sesuai dengan kasus - kasus yang mungkin terjadi di lapangan. PT IMS menjalankan skenario testing tanpa adanya monitoring sehingga sulit untuk memonitor proses pengujian yang dijalankan. Penelitian ini dilakukan agar proses yang berjalan saat ini dapat termonitor dengan baik sehingga dibuatkan aplikasi skenario testing. Aplikasi skenario testing dapat memonitor melalui report dan grafik pengerjaan yang dilakukan.

Effects of β-sitosterol on growth, development and midgut enzymes of Helicoverpa armigera Hübner
Authors: Mishra Monika , Sharma Aarti , Dagar Vinay , Kumar Sarita
Published: May 2020

Helicoverpa armigera is a global agricultural pest of serious concern. Continued use of chemical insecticides as control measures has raised grave health and environment concerns, necessitating a search for botanicals as safe alternatives. The current study investigates the effects of ?-sitosterol, a bioactive phytocomponent in Thevetia neriifolia, on the growth and development, as well as on midgut enzymes of H. armigera. Dietary ?-sitosterol produced dose-dependent systemic toxicity and growth inhibitory effects in H. armigera; the most significant effects were obtained with 10 ?g/mL dietary ?-sitosterol. Higher prepupal and pupal mortality in comparison to larval mortality and a comparatively greater reduction in average weight gained by later instars point to cumulative effects of ?-sitosterol. The delayed effects were ascertained by the 82.05%-57.89% reduction in adult emergence in comparison to 95.02% emergence in controls. Dose-dependent effects of ?-sitosterol were observed as significantly decreased enzyme activities of alanine aminotransaminase (ALT), aspartate aminotransaminase (AST) and alkaline phosphatase (ALP) in the larval midgut. Suppression of enzyme activity was obtained in the order ALT>AST>ALP. Impaired activity of gut enzymes possibly lowered the energy reserves and affected nutrient transport through the gut epithelium, affecting the growth and development of H. armigera. Our study points to a promising use of ?-sitosterol against H. armigera, although further examination and field studies are needed to ascertain its possible use in control programs.
Psicopedagogía crítica para conceptos epistémicos y sociales en investigación universitaria
Authors: Condori Nina Mario
Published: May 2020

El objetivo de este trabajo fue proponer nuevas definiciones de términos epistémicos que son utilizados en el ámbito universitario y particularmente en ciencias socioculturales: gnoseología, epistemología y teoría del conocimiento, por un lado, y por el otro, los términos de explicación y comprensión. Para ello, estos conceptos pasaron por una exposición descriptiva para posteriormente ser tratados psicopedagógica y sociocríticamente, lo cual permitió conocer los pormenores intrínsecos que tienen cada uno ellos; este proceso garantizó una base teórica que permitió y fundamentó la propuesta de nuevas concepciones de los cinco términos en cuestión. Aparte del método de trabajo de campo de investigación, se utilizó el análisis teórico discriminante, el método descriptivo, el inductivo, el análisis-síntesis y de posición, el de la elevación de lo abstracto a lo concreto y lo histórico-lógico; también se recurrió al paradigma sociocrítico, al método propositivo y, particularmente, al método de la filofización de los hechos. Entre los resultados, primero, se logró cumplir con el objetivo de formular nuevas proposiciones conceptuales para los términos epistémicos y sociales ya mencionados; segundo, se detectó que cada uno de los autores revisados tiene una posición conceptual distinta respecto a un solo término universal, lo cual lleva a la confusión; tercero, las tres epistemes de la gnoseología, la epistemología y la teoría del conocimiento son sinónimas, pero la epistemología se diferencia de las otras dos por ser la única que implica un tratamiento del método; y cuarto, respecto a los términos sociales de explicación y comprensión, ambos pueden contribuir ya sea de manera separada o conjunta a las ciencias físicas, naturales y sociales, pero el último de alguna forma se diferencia del primero porque es más profundo en su actuar en relación con todo tipo de hechos: si bien permite ver cuestiones objetivas, principalmente es útil para temas intersubjetivos y trascendentales de todo tipo de hechos materiales y humanos.
Crónicas para una Historia de la Edición y la Lectura en el siglo XIX. La Biblioteca Americana de Alejandro Magariños Cervantes
Authors: Valinoti Beatriz Cecilia
Published: May 2020

La Biblioteca Americana era una colección que, en palabras de Alejandro Magariños Cervantes, estaba destinada a difundir material inédito de los más notables autores americanos. Si bien este proyecto había comenzado en París en 1854, los tomos siguientes fueron publicados en Buenos Aires y Montevideo entre 1858 y 1864. Interesa destacar que en cada libro el editor incluyó algunas páginas que denominó “Crónica de la Biblioteca”, donde presentaba ideas relacionadas con el plan general de la obra, intercambios epistolares, juicios críticos, listas de suscriptores, circuitos de distribución y lugares de comercialización. Todo esto sin dejar de dar cuenta de las dificultades con la impresión, tanto por los retrasos de los autores en entregar las obras como por cuestiones de producción debidas a la falta de papel. A dichos factores se le sumaban los altos costos y las pocas ganancias materiales que se obtenían al llevar adelante esta empresa. De modo que, el objetivo de este artículo es estudiar las crónicas para reconstruir el devenir de un catálogo, comparando los autores y las obras que anuncia publicar Alejandro Magariños Cervantes con el contenido definitivo de la colección. A la vez, se plantea rastrear indicios de prácticas y usos asociados al libro a mediados del siglo XIX.
Coleções de livros de bolso no Brasil: notas sobre a Biblioteca Universal Popular
Authors: Ribeiro Ana Elisa , Karam Sérgio
Published: May 2020

Estão em foco, neste trabalho, ao menos dois elementos da edição importantes para a compreensão dos modos de produção e circulação dos livros no Brasil: as noções de “livro popular” e de “livro de bolso”, ambas estreitamente relacionadas entre si e também a estratégias de produção e venda, formatos, design e certos gêneros, aqui no sentido de gêneros literários ou gêneros “de livraria”. Trataremos aqui, para fins de discussão conceitual, mas também para uma análise de práticas editoriais, da Biblioteca Universal Popular, coleção de livros de bolso publicada no país entre 1963 e 1968 pela Editora Civilização Brasileira, uma das mais importantes casas editoriais em atividade naquele momento. Outro aspecto relevante do presente estudo é a recomposição do catálogo da referida coleção, que representa uma das muitas tentativas de editoras brasileiras de acercar-se ao mercado dos livros de bolso por meio da edição de livros de baixo custo e ampla circulação. A coleta e a organização das informações aqui elencadas deram-se com base em consultas a bibliotecas particulares e a diversos sites, especialmente o acervo on-line da Fundação Biblioteca Nacional e a Estante Virtual.
As influências das garantias de ficção, literária e de uso na indexação da literatura infantojuvenil
Authors: Alves Roberta Caroline Vesu
Published: May 2020

As garantias de ficção, literária e de uso foram verificadas com objetivo de observar se fundamentam a elaboração de modelo de leitura documental para indexação de texto narrativo ficcional em prosa, nos aspectos de identificação de assuntos, seleção e representação. A metodologia consistiu em pesquisa bibliográfica e estudo exploratório para o desenvolvimento do modelo de leitura documental, este avaliado por bibliotecários escolares, também por meio da metodologia do protocolo verbal individual para verificação e aprimoramento do modelo. Como resultados, as garantias de ficção, literária e de uso contribuíram com a fundamentação do modelo de leitura documental para a indexação da literatura infantojuvenil conforme observado na avaliação do modelo. Alguns aspectos da estrutura do modelo foram aprimorados. Os elementos do texto importantes para representação e recuperação da informação por usuários estão relacionados com as garantias e foram evidenciados pelos aspectos de personagens, ação ou evento, espaço, tempo, tema ou assunto, narrador, gêneros literários, temas educacionais do ponto de vista do autor e alguns aspectos cognitivos do leitor. O modelo empírico de leitura documental foi fundamentado pelas garantias e foi importante para indexação por bibliotecários escolares, que aprovaram o modelo e mostraram modos para seu aprimoramento.
