Peer-to-Peer Social Media as an Effective Prevention Strategy: Quasi-Experimental Evaluation
Authors: Evans William , Andrade Elizabeth , Pratt Michaela , Mottern Alexandra , Chavez Sergio , Calzetta-Raymond Anthony , Gu Jiayan 
Published: February 2020

Background
Substance use by adolescents remains to be at unacceptably high levels, and there is evidence that teens’ social norms are becoming more favorable toward recreational use and perceived safety of substances such as marijuana and prescription opioids. Social media offer a low-cost, potentially high-impact approach to disseminate prevention messages.

Objective
Living the Example (LTE) is a program that trains adolescent youth ambassadors to develop and disseminate prevention messages within their own social media networks and through in-school activities. This study aimed to evaluate the effects of exposure to LTE-based social media on students in the youth ambassadors’ networks.

Methods
The George Washington (GW) University designed and implemented a quasi-experimental evaluation of the LTE program in 3 Maryland high schools. Before program launch, a sample of 826 students (wave 1) at the 3 schools, drawn from a census of freshmen enrolled in a class attended by all students at the grade level, completed a survey. A total of 584 students were surveyed at the wave 2 program midpoint and 542 at the wave 3 endpoint. The survey contained questions on drug use–related attitudes, beliefs, intentions, and behaviors, all based on validated measures. We evaluated the effects of LTE on the intended next 30-day drug use, and controlling for LTE self-reported exposure, age, and gender from waves 2 and 3 was appended into a single dataset. We first conducted ordinal logistic regressions for each drug use intention in wave 3 (ie, sell or distribute illegal drugs, smoke cigarettes, drink beer/wine/hard liquor when parents do not know about it, use marijuana, use lysergic acid diethylamide, cocaine, amphetamines or other illegal drugs, use heroin, use synthetic drugs, and use any prescription pills without a prescription) to examine the association between LTE exposure and drug use intentions. We included an interaction term for the study wave to examine intervention effects.

Results
We found a significant positive effect of LTE exposure on all 8 measured drug use intentions: sell/distribute illegal drugs; smoke cigarettes; drink beer, wine, or liquor when my parents do not know about it; use marijuana; use cocaine, amphetamines, or other illegal drug; use heroin; use synthetic drugs; use any prescription pills without a prescription (all P<.05; odds ratios ranging from 2.12 to 3.71). We also found that boys were more likely than girls to exhibit reduced drug use intentions. We also found reductions in 30-day intentions between the second and third survey waves for all 8 measured drug use variables.

Conclusions
Overall, the results are consistent with and indicate a stronger LTE effect in this study compared with a previous pilot study. LTE appears to offer a protective effect, with exposure to program messages leading to reduced/improved drug use intentions.
The Model of Gamification Principles for Digital Health Interventions: Evaluation of Validity and Potential Utility
Authors: Floryan Mark , Chow Philip I , Schueller Stephen M , Ritterband Lee M 
Published: February 2020

Background
Although gamification continues to be a popular approach to increase engagement, motivation, and adherence to behavioral interventions, empirical studies have rarely focused on this topic. There is a need to empirically evaluate gamification models to increase the understanding of how to integrate gamification into interventions.

Objective
The model of gamification principles for digital health interventions proposes a set of five independent yet interrelated gamification principles. This study aimed to examine the validity and reliability of this model to inform its use in Web- and mobile-based apps.

Methods
A total of 17 digital health interventions were selected from a curated website of mobile- and Web-based apps (PsyberGuide), which makes independent and unbiased ratings on various metrics. A total of 133 independent raters trained in gamification evaluation techniques were instructed to evaluate the apps and rate the degree to which gamification principles are present. Multiple ratings (n≥20) were collected for each of the five gamification principles within each app. Existing measures, including the PsyberGuide credibility score, mobile app rating scale (MARS), and the app store rating of each app were collected, and their relationship with the gamification principle scores was investigated.

Results
Apps varied widely in the degree of gamification implemented (ie, the mean gamification rating ranged from 0.17≤m≤4.65 out of 5). Inter-rater reliability of gamification scores for each app was acceptable (κ≥0.5). There was no significant correlation between any of the five gamification principles and the PsyberGuide credibility score (P≥.49 in all cases). Three gamification principles (supporting player archetypes, feedback, and visibility) were significantly correlated with the MARS score, whereas three principles (meaningful purpose, meaningful choice, and supporting player archetypes) were significantly correlated with the app store rating. One gamification principle was statistically significant with both the MARS and the app store rating (supporting player archetypes).

Conclusions
Overall, the results support the validity and potential utility of the model of gamification principles for digital health interventions. As expected, there was some overlap between several gamification principles and existing app measures (eg, MARS). However, the results indicate that the gamification principles are not redundant with existing measures and highlight the potential utility of a 5-factor gamification model structure in digital behavioral health interventions. These gamification principles may be used to improve user experience and enhance engagement with digital health programs.
An Informatics Framework to Assess Consumer Health Language Complexity Differences: Proof-of-Concept Study
Authors: Yu Biyang , He Zhe , Xing Aiwen , Lustria Mia Liza A 
Published: February 2020

Background
The language gap between health consumers and health professionals has been long recognized as the main hindrance to effective health information comprehension. Although providing health information access in consumer health language (CHL) is widely accepted as the solution to the problem, health consumers are found to have varying health language preferences and proficiencies. To simplify health documents for heterogeneous consumer groups, it is important to quantify how CHLs are different in terms of complexity among various consumer groups.

Objective
This study aimed to propose an informatics framework (consumer health language complexity [CHELC]) to assess the complexity differences of CHL using syntax-level, text-level, term-level, and semantic-level complexity metrics. Specifically, we identified 8 language complexity metrics validated in previous literature and combined them into a 4-faceted framework. Through a rank-based algorithm, we developed unifying scores (CHELC scores [CHELCS]) to quantify syntax-level, text-level, term-level, semantic-level, and overall CHL complexity. We applied CHELCS to compare posts of each individual on online health forums designed for (1) the general public, (2) deaf and hearing-impaired people, and (3) people with autism spectrum disorder (ASD).

Methods
We examined posts with more than 4 sentences of each user from 3 health forums to understand CHL complexity differences among these groups: 12,560 posts from 3756 users in Yahoo! Answers, 25,545 posts from 1623 users in AllDeaf, and 26,484 posts from 2751 users in Wrong Planet. We calculated CHELCS for each user and compared the scores of 3 user groups (ie, deaf and hearing-impaired people, people with ASD, and the public) through 2-sample Kolmogorov-Smirnov tests and analysis of covariance tests.

Results
The results suggest that users in the public forum used more complex CHL, particularly more diverse semantics and more complex health terms compared with users in the ASD and deaf and hearing-impaired user forums. However, between the latter 2 groups, people with ASD used more complex words, and deaf and hearing-impaired users used more complex syntax.

Conclusions
Our results show that the users in 3 online forums had significantly different CHL complexities in different facets. The proposed framework and detailed measurements help to quantify these CHL complexity differences comprehensively. The results emphasize the importance of tailoring health-related content for different consumer groups with varying CHL complexities.
Parent Perspectives on Family-Centered Pediatric Electronic Consultations: Qualitative Study
Authors: Verma Rhea , Krishnamurti Tamar , Ray Kristin N 
Published: February 2020

Background
Electronic consultations, which use store-and-forward transfer of clinical information between a primary care physician and a specialist, improve access to specialty care. Adoption of electronic consultations is beginning in pediatric health care systems, but little is known about parent perspectives, informational needs, and preferences for interaction with this new model of care.

Objective
This study aimed to examine parent perspectives about electronic consultations, including perceived benefits and risks, anticipated informational needs, and preferences for parent engagement with electronic consultations.

Methods
We recruited caregivers of pediatric patients (aged 0-21 years) attending visits at an academic primary care center. Caregivers were eligible if their child had ever been referred for in-person specialty care. Caregivers participated in a semistructured interview about electronic consultations, including general perspectives, desired information, and preferences for parental engagement. Interviews were transcribed and qualitatively analyzed to identify parent perspectives on electronic consultations in general, information parents would like to receive about electronic consultations, and perspectives on opportunities to enhance parent engagement with electronic consultations.

Results
Interviewees (n=20) anticipated that electronic consultations would reduce the time burden of specialty care on families and that these had the potential to improve the integrity and availability of clinical information, but interviewees also expressed concern about data confidentiality. The most detailed information desired by interviewees about electronic consultations related to data security, including data confidentiality, availability, and integrity. Interviewees expressed concern that electronic consultations could exclude parents from their child’s health care decisions. Interviewees saw value in the potential ability to track the consultation status or to participate in the consultation dialogue, but they were more ambivalent about the idea of read-only access to consultation documentation.

Conclusions
Parents identified the potential risks and benefits of pediatric electronic consultations, with implications for communication with families about electronic consultations and for incorporation of features to enhance parent engagement.

El objetivo del estudio fue analizar las frecuencias alélicas de 28 Polimorfismos de un solo nucleótido (SNP) localizados en genes candidatos para crecimiento en bovinos, así como determinar su efecto sobre rasgos de peso vivo en hatos de las razas Charolais y Simmental. Se tomaron muestras de pelo de 313 animales provenientes de cinco hatos ubicados en cuatro municipios de Tamaulipas y se genotipificaron con la tecnología de Sequenom Mass Array.Todos los marcadores resultaron ser polimórficos en las poblaciones evaluadas y sus frecuencias alélicas fueron significativamente diferentes entre razas (P<0.05). El análisis de asociación determinó que en los animales de la raza Charolais, el marcador PRL+2723 tiene un efecto significativo (P=0.0350) sobre el peso al nacimiento y el marcador localizado en el gen GHR (GHR-6.1), sobre peso al destete (P=0.0226). El GHR-6.1 también se asoció con el peso al año en los animales de la raza Simmental. El marcador LEP-3100 (P=0.0249) también tuvo un efecto significativo sobre el peso al destete en los animales Simmental.El panel probado es polimórfico en las dos razas evaluadas y tres de los marcadores tuvieron efecto significativo en los parámetros de peso vivo evaluados, por lo que tienen el potencial de validarse y usarse como una herramienta adicional en la selección y mejoramiento genético del ganado de carne en Tamaulipas.
Competências interculturais na educação superior
Authors: Clemente Fabiane Aparecida Santos , Morosini Marilia Costa 
Published: February 2020

Um dos desafios da educação superior no Brasil é buscar compreender a complexidade do contexto “emergente”. Isso inclui um repensar sobre conceitos latentes, entre eles, o de competências interculturais. Esse texto busca trazer uma reflexão sobre o desenvolvimento de competências interculturais na educação superior brasileira a partir da perspectiva discente. O caminho percorrido se baseou em pesquisa quali-quantitativa, com suporte em questionário, em uma universidade pública da Amazônia. Os resultados apontam para a predominância do conceito de competência como input (PARRY, 1996) e a interculturalidade funcional (WALSH, 2009), mesmo que não seja com ações ou modelos sistematizados. Destaca-se a necessidade de institucionalização de ações que visam o desenvolvimento de competências interculturais na educação superior, envolvendo os atores desse contexto e a importância de difusão do conceito.

Authors: Öztekin Gölgen Bahar , Tüzel Yüksel 
Published: February 2020

This study was conducted in order to determine the effects of oxygen enrichment of nutrient solution coupled with plant growth promoting rhizobacteria on soilless grown iceberg lettuce (cv. ‘Papiro’) production. Seeds were treated with Bacillus subtilis, Pseudomonas putida, P. fluorescens, P. punonensis and combined application of B. subtilis + P. fluorescens and were sown into vermicompost : peat (1 : 1.5, v/v) mixture on January 14th, 2015. After germination in growth chamber, seedlings were moved to a greenhouse for seedling growing till they were ready for planting. Seedlings were transplanted to the polyethylene greenhouse 35 days after sowing. Perlite as growing medium was used in open-system soilless culture. Nutrient solution was aerated with an air compressor and applied to plants 2 days after planting with drip irrigation. To diffuse oxygen into nutrient solution in large bubbles, a circular air-stone commonly used in fisheries was used. The nutrient solution without oxyfertigation and plants not treated with bacteria constituted the control treatment. Experiments were conducted in randomized plots design with 2 factors and 3 replications. Heads were harvested 2 months after transplanting. Yield and head quality parameters of head were determined. It was concluded that oxygen enrichment of nutrient solution through a compressor (aeration) provided increases in yield and plant growth. Especially root development, head size and leaf number were higher in plants grown with aerated nutrient solution. Among the tested bacteria, B. subtilis, P. fluorescens and B. subtilis + P. fluorescens were found promising due to the their higher performance under aerated conditions on greenhouse lettuce grown in perlite.
Antihipercolesterolemia Effects and Acute Toxicity Test of Pheophytin on Green Tea
Authors: Kusmita Lia , Puspitaningrum Ika 
Published: February 2020

Hypercholesterolemia is a condition characterized by increased levels of total cholesterol in the blood. Pheophytin is the result of degradation of chlorophyll which is the dominant pigment in green tea, and has been shown to have the same antioxidant properties as - carotene. This study aims to determine the antihypercholesterolemia effect and effective dose of pheophytin isolates and acute toxicity tests to determine the safety level of pheophytin isolates.
Antihipocolesterolemia test uses induction of high-fat feed that is a mixture of standard food, pork oil and quail egg yolk (16: 3: 1). While the acute toxicity test is carried out based on OECD 423, Clinical symptoms that arise for 3 hours are observed intensively. Histopathological examination data of liver and kidney organs were performed on day 14. Data obtained in the form of LD 50 and clinical symptoms that arise as well as histopathological results were analyzed qualitatively.
Statistical test results of percent reduction in total cholesterol levels showed a significant difference between the negative control group and the pheophytin isolates of the three doses. This proves that pheophytin isolates can have antihypercholesterolemic effect with an effective dose of 10 mg/kgBW. Histopathological examination results of aorta and liver of rats showed that the higher the dose of pheophytin isolates, the lighter the degree of fatty acid. While the toxicity test results showed that the LD50 value of pheophytin isolates was more than 2000 mg / kgBW (non-toxic category). However, pheophytin isolate with LD50 is more than 2000 mg/kgBW which has shown the presence of pancreatic degeneration and hydropic degeneration, but necrosis has not occurred yet.
La construcción de la Base Nacional Común Curricular (BNCC) de Historia en Brasil: entre diálogos, tensiones y controversias
Authors: Cerri Luis Fernando , Costa Maria Paula 
Published: February 2020

Brasil vive un turbulento momento político que tuvo su primer auge con el golpe jurídico-parlamentario contra la presidenta Dilma Rousseff. Mismo con un proceso en curso de inestabilidad política y económica se da continuidad a una serie de propuestas en el campo educativo, entre las que se inserta la construcción de una Base Nacional Común Curricular. El objetivo de este texto es problematizar como algunos historiadores se posicionan frente a la publicación, en 2015, de la primera versión de la Base Nacional Común Curricular para el componente Historia. Las disputas y conflictos ocurrieron, pues la BNCC proponía una remodelación en las narrativas históricas enfatizando la Historia de Brasil y sus orígenes amerindias y africanas balizando el lugar de la historia antigua y medieval. Las críticas que siguieron a la publicación de este documento preliminar no se restringieron al espacio de las universidades y de las asociaciones representativas, pero involucraron a los editores y autores de libros didácticos, políticos conservadores, religiosos fundamentalistas y periodistas sensacionalistas. Este artículo analiza una muestra de textos académicos y periodísticos que estructuraron el debate y propone un análisis preliminar de los argumentos utilizados y su relación con las posturas político-académicas, identificando posibles categorías para futuros análisis de contenido.
Santiago Robledo Páez, Escribir una autobiografía en el Nuevo Reino de Granada: estudio sobre las Observaciones curiosas y doctrinales de Joseph Ortiz y Morales. Bogotá: ICANH, 2018. 172 p.
Authors: Cruz Medina Juan Pablo 
Published: February 2020

Durante décadas la práctica historiográfica se ha basado, fundamentalmente, en una relación hermenéutica con ese pasado que se instituye como su objeto de estudio. A partir de dicha asociación, la “escritura de la historia” ha pretendido descifrar los hechos pasados imponiéndoles categorías que permitan reducirlos de tal forma que puedan ser objeto de un riguroso análisis. La historia, entendida como escritura de los hechos del pasado (Rerum Gestarum), se convirtió así en “la ciencia de los hombres en el tiempo”[1], una disciplina científica cifrada en la pretensión de verdad. Gracias a esto el binomio “historia” / “literatura” se constituyó como antítesis, a partir de la tajante separación entre “verdad” y “ficción”, dando forma desde el siglo XIX a los límites disciplinares de lo que Michel de Certeau denomina como la “operación historiográfica”[2]. Pero, ¿qué es literatura y qué es historia? ¿Podemos realmente aplicar estas categorías ─incubadas en el siglo XIX─ a los textos producidos en los siglos XVI, XVII, y XVIII? Estas cuestiones encierran el problema al que Santiago Robledo Páez hace frente en el recientemente publicado Escribir una autobiografía en el Nuevo Reino de Granada: estudio sobre las Observaciones curiosas y doctrinales de Joseph Ortiz y Morales.

A Study of Gas Diffusion Characteristics on Nano-Structured Ceramic Membranes
Authors: Ogunlude Priscilla , Abunumah Ofasa , Gobina Edward 
Published: February 2020

Abstract
The use of membranes for gas upgrading has increasingly become of interest as it has shown great potential for efficient and affective gas purification and a pathway to green energy. The emission of greenhouse gases to the atmosphere has detrimental effects on the economy in terms of global warming which has led to many natural disasters, heat waves, food shortage, loss of life and property. To combat this, studies of capturing and utilizing greenhouse gases are ongoing. In this paper, the study of biogas components (methane and carbon dioxide) diffusion through membranes are studied to employ its use as a solution for the challenge. The study involved the use of membranes of different pore sizes (15, 200 and 6000nm) to ascertain the flow characteristics and regime of the gases under different operating conditions. Single gas permeation tests were conducted, and the results show the flow of gases is dependent on factors including molecular weight, kinematic diameter and viscosity of the gas components. It was observed that pressure has a greater influence on the gas flow through membranes compared to temperature with the effect of pore size having the greatest impact. The flux of methane through the membrane is greater than that of carbon dioxide in regular pore geometry and depicts a greater potential for upgrading of biogas.
