Low Testosterone on Social Media: Application of Natural Language Processing to Understand Patients’ Perceptions of Hypogonadism and Its Treatment (Preprint)
Authors: Osadchiy Vadim , Jiang Tommy , Mills Jesse Nelson , Eleswarapu Sriram Venkata
Published: October 2020

BACKGROUND

Despite the results of the Testosterone Trials, physicians remain uncomfortable treating men with hypogonadism. Discouraged, men increasingly turn to social media to discuss medical concerns.

OBJECTIVE

The goal of the research was to apply natural language processing (NLP) techniques to social media posts for identification of themes of discussion regarding low testosterone and testosterone replacement therapy (TRT) in order to inform how physicians may better evaluate and counsel patients.

METHODS

We retrospectively extracted posts from the Reddit community r/Testosterone from December 2015 through May 2019. We applied an NLP technique called the meaning extraction method with principal component analysis (MEM/PCA) to computationally derive discussion themes. We then performed a prospective analysis of Twitter data (tweets) that contained the terms low testosterone, low T, and testosterone replacement from June through September 2019.

RESULTS

A total of 199,335 Reddit posts and 6659 tweets were analyzed. MEM/PCA revealed dominant themes of discussion: symptoms of hypogonadism, seeing a doctor, results of laboratory tests, derogatory comments and insults, TRT medications, and cardiovascular risk. More than 25% of Reddit posts contained the term doctor, and more than 5% urologist.

CONCLUSIONS

This study represents the first NLP evaluation of the social media landscape surrounding hypogonadism and TRT. Although physicians traditionally limit their practices to within their clinic walls, the ubiquity of social media demands that physicians understand what patients discuss online. Physicians may do well to bring up online discussions during clinic consultations for low testosterone to pull back the curtain and dispel myths.
Divergence and the Complexity of Difference in Text and Culture
Authors: Chang Kent K. , DeDeo Simon
Published: October 2020

Measuring how much two documents differ is a basic task in the quantitative analysis of text. Because difference is a complex, interpretive concept, researchers often operationalize difference as distance, a mathematical function that represents documents through a metaphor of physical space. Yet the constraints of that metaphor mean that distance can only capture some of the ways that documents can relate to each other. We show how a more general concept, divergence, can help solve this problem, alerting us to new ways in which documents can relate to each other. In contrast to distance, divergence can capture enclosure relationships, where two documents differ because the patterns found in one are a partial subset of those in the other, and the emergence of shortcuts, where two documents can be brought closer through mediation by a third. We provide an example of this difference measure, Kullback–Leibler Divergence, and apply it to two worked examples: the presentation of scientific arguments in Charles Darwin’s Origin of Species (1859) and the rhetorical structure of philosophical texts by Aristotle, David Hume, and Immanuel Kant. These examples illuminate the complex relationship between time and what we refer to as an archive’s “enclosure architecture”, and show how divergence can be used in the quantitative analysis of historical, literary, and cultural texts to reveal cognitive structures invisible to spatial metaphors.
Exploring effective factors for improving instructors’ job satisfaction in vocational and traditional training institutes in Bhutan
Authors: Penjor Kinley
Published: October 2020

This article aims to study the effective factors for improving instructors' job satisfaction in vocational and traditional training institutes in Bhutan. The study was conducted using quantitative and qualitative methods. The population consisted of 75 instructors working in six technical training institutes and one traditional training institute in Bhutan. A descriptive survey was carried out with 75 instructors and interviews were conducted with 33 instructors. The career ladder, conducive learning environment, adequate tools and equipment were the main reasons leading to job satisfaction of the instructors. Institute management also leads to their job satisfaction. Their general opinions indicated that a clear and appropriate career ladder for instructors must be put in place, timely (four years) promotion should be awarded, the conducive working environment should be created, opportunities for training and retraining must be provided and acknowledging their contributions for achieving the common goals of the institute would enhance the instructors’ job satisfaction. Based on the findings, it is recommended to improve and develop the management practices and increase the level of job satisfaction of instructors by extending support from the Ministry of Labour and Human Resources. This should prevent job dissatisfaction and lead to a better-quality training system in Bhutan.

STRATEGIJA KOMUNIKACIJE GRADSKE UPRAVE GRADA BEOGRADA -PRIMERI DVA SEKRETARIJATA
Authors: Katana Ljupka
Published: October 2020

Predmet rada predstavlja osvrt na komunikacijske alate javne uprave Republike Srbije, kojima možemo sagledati strategiju komunikacije zaposlenih u kontaktu sa građanima. Ovu njihovu strategiju, pomsatramo na primeru gradske uprave grada Beograda i sekretarijata u okviru iste. Polazimo, najpre od definicije javne uprave kao pojma od kojeg počinje institucionalna komunikacija u državi. Potom, kroz opis gradske uprave grada, dajemo uvid u međusobnu povezanost ovih sistema upravljanja. Time, istraživanje svodimo tako da dolazimo do cilja rada. Cilj istraživanja jeste da se sagledaju alati komunikacije u svakodnevnom radu ovih institucija sa građanima, odnosno svrsishodnost njihove funkcije i otvorenost ka građanima, ukoliko ona postoji. Metode koje se koriste u radu predstavljaju retrospektivnu analizu podataka, analizu komunikacije i analizu strategije kojom se vode zaposleni. Kao posledica loše komunikacije mogu se javiti mnoge nepravilnosti u radu, posebno usled nedostatka veština asertivnosti i otvorenosti ka građanima, kao glavnim korisnicima institucionalne vlasti. Metode se sprovode i kroz tehniku intervjua, građana kao i načelnika sekretarijata koje opisujemo u radu i/ili osoba zaduženih za komunikaciju i medije. Rezultati su pokazali da je trenutno stanje komunikacione prakse javnih institucija na zadovoljavajućem nivou, ali da su potrebne određene promene kako bi se postigla efikasnija, efektivnija i humanija komunikacija sa građanima, kao najznačajnijim korsnicima usluga gradskih sekretarijata.

Estudiar el caso del mestizo y del mestizaje en la hoy nombradaLatinoamérica o América Latina, tal como se haría una constante denominarlaen el último tercio del siglo XIX, concita a volcar la mirada en los contenidos de las voces mestizo y mestizaje. Aunque su estudio guardaestrecha relación con los usos que se han difundido de los mismos, en elseno de las distintas narrativas que han buscado con afán caracterizar entérminos culturales a la América Latina. De ahí la necesidad de hurgar en laconnotación histórica otorgada a los términos mestizo, mestizaje y mestizar,propuestas desde el canon occidental y las narrativas tramadas desde laperiferia al amparo del espacio occidental y la mundialización cultural.
El principio empírico de imposibilidad y la satisfacción de las necesidades en Franz Hinkelammert
Authors: Arellano Lázaro José Manuel
Published: October 2020

Para Hinkelammert la acción humana está limitada por varios ámbitos,el económico, el político, el tecnológico, etc., pero en última instanciaestá limitada por la satisfacción de las necesidades. Ya que aun si el ser humanono reproduce su vida se muere, por ello la satisfacción de las necesidadeses el límite más allá del cual no podemos ir. Así, el autor nos proponeun principio para juzgar la factibilidad de todas nuestras acciones y proyectosde vida (el principio empírico de imposibilidad). Si un proyecto de vida ouna institución contradice o impide la reproducción y crecimiento de la vidaserá perverso. Por ello la ética comienza cuando afirmamos la vida y negamosla muerte.
EL PATHOS TRÁGICO DE EL GENERAL EN SU LABERINTO. ENTRE LA HISTORIA Y LA EXPRESIÓN
Authors: Urdapilleta Muñoz Marco
Published: October 2020

Este artículo se circunscribe en la polémica recepción deEl general en su laberinto que en un primer momento se inclinó porevaluar negativamente la novela argumentando que la imagen delprócer era dañada y que distorsionaba la verdad histórica. La respuestaa estas opiniones fue rápida y certera: la novela es el arte dela ficción. Incluso se dijo que a la postre la imagen novelesca de Bolívarera más verosímil que la del culto oficial. Así se argumentó queaquello que aparentemente denigraba a Bolívar en realidad perseguíauna simple humanización lograda al desmitificar al héroe de laepopeya. Aquí se propone que no hay tal desmitificación, más biense observa que el Bolívar de García Márquez sigue nítidamente elperiplo del héroe que inicia su caída, hecho que sin duda alguna revelael pathos trágico de la novela.

Manifestaciones de la religiosidad popular en torno a tres imágenes marianas originarias. La unidad del ritual y la diversidad formal
Authors: Vences Vidal Magdalena
Published: October 2020

El artículo aborda el tema de la religiosidad popular a través del cultoa tres imágenes marianas durante la Colonia: la Virgen de Guadalupe del Tepeyac (México), la Virgen del Rosario de Chiquinquirá (Colombia) y la Virgen de El Quinche (Ecuador). Estos tres casos hispanoamericanos son referente para que la autora reflexione, en la primera parte, sobre los conceptos utilizados para explicar el comportamiento religioso del pueblo―principalmente la religiosidad, lo popular y lo oficial―; a partir del análisis de autores españoles que tratan estos conceptos, expone el papel que desempeñaron las manifestaciones colectivas externas en torno a las imágenes y fenómenos como el milagro y la fiesta. En la segunda parte, la autora describe los medios usados para afianzar y expandir el culto a las imágenes sagradas, en donde destaca el importante papel que tuvieron los traslados de las imágenes y sus reproduccionesplásticas. Finalmente, analiza los conceptos de cultura y del barroco.
Practice for the determination of convective coefficients
Authors: Durán Peralta Héctor Armando , Mayorga Betancourt Manuel Alejandro , Cordoba Castrillón Luis Fernando
Published: October 2020

 El presente documento muestra cómo determinar el coeficiente de transferencia de calor en convección libre, utilizando datos de temperatura, leídos en forma de intervalo, alrededor del bulbo de un termómetro de vidrio. Para esto, se realizó el experimento de enfriamiento del bulbo de un termómetro y se registraron los datos del descenso del menisco del termómetro. Se construyeron dos modelos de transferencia de calor para el enfriamiento del bulbo, con su respectiva solución analítica. En el primer modelo, se consideró la temperatura del bulbo de mercurio igual a la temperatura de la envoltura de vidrio, mientras que en el segundo modelo no se consideró esta restricción. Con las soluciones analíticas de estos modelos y usando un método de mínimos cuadrados modificado para trabajar con datos leídos en forma de intervalo, se determinó el coeficiente experimental de transferencia de calor en forma de intervalo. Para validar ambos modelos, las temperaturas calculadas se graficaron y compararon con los datos experimentales. Los resultados muestran que el coeficiente de transferencia de calor calculado con el modelo sin restricciones es el que mejor representa los datos experimentales.

Measuring the incidence of social factors on scientific research: A socio-scientometrics analysis of strategic countries
Authors: Lancho-Barrantes Barbara S. , Cantu-Ortiz Francisco J.
Published: October 2020

En la literatura científica algunos estudios han examinado el impacto positivo que tiene la investigación en la sociedad. Sin embargo, este trabajo analiza cómo los factores sociales pueden influir en los resultados científicos. La muestra de investigación estudia a México y sus socios estratégicos en ciencia y tecnología. Los resultados se dividen en tres partes, la primera muestra la relación entre población, inversión pública en educación superior, gasto interno bruto en I+D (GERD) (como porcentaje del Producto Interno Bruto (PIB)), número de investigadores y los resultados científicos (producción científica y citas recibidas). La segunda parte se centra en la relación entre la movilidad del investigador (sedentario o migratorio (flujos de entrada y salida, estancias transitorias)) y la producción en colaboración. La tercera parte analiza si las preferencias en investigación de los países tienen una repercusión en el conjunto total de la producción científica. Este estudio facilita una mejor comprensión de las contribuciones sociales al desarrollo científico y socioeconómico de los países y es útil para que los gobiernos y los responsables políticos tengan en cuenta la importancia de estas variables sociales y, como resultado, conducir a los países hacia la excelencia en ciencia.
Abuso digital nas relações amorosas: um estudo das representações sociais com universitários brasileiros

Published: October 2020

O presente estudo objetivou apreender as representações sociais (RS) de universitários brasileiros acerca do abuso digital nos relacionamentos amorosos (ADRA). Participaram da pesquisa 447 participantes os quais responderam à Técnica de Associação Livre de Palavras e ao Questionário de Abuso Digital nos Relacionamentos Amorosos (QADRA). Os dados apontaram para uma alta prevalência de envolvimento no ADRA, tanto em vitimização (87,6% controle/monitoramento; 34,7%, agressão direta); quanto, em perpetração (92,6% controle/monitoramento; 25,1%, agressão direta). Além disso, os resultados indicaram que os elementos estruturantes das RS se ancoraram na incerteza relacional contemporânea e na concepção de dominância dentro dos relacionamentos íntimos. Quanto as evocações do núcleo periférico, o ADRA foi ancorado na violação dos direitos à privacidade e nas suas causas e consequências, perpassando aspectos psicoafetivos e sociais. Finalmente, os dados revelaram que o "ciúme" se apresenta como elemento central e organizador das RS desse fenômeno, motivando ações virtuais abusivas.
Weak-ergodicity-breaking via lattice supersymmetry
Authors: Surace Federica Maria , Giudici Giuliano , Dalmonte Marcello
Published: October 2020

We study the spectral properties of D-dimensional N=2 supersymmetric lattice models. We find systematic departures from the eigenstate thermalization hypothesis (ETH) in the form of a degenerate set of ETH-violating supersymmetric (SUSY) doublets, also referred to as many-body scars, that we construct analytically. These states are stable against arbitrary SUSY-preserving perturbations, including inhomogeneous couplings. For the specific case of two-leg ladders, we provide extensive numerical evidence that shows how those states are the only ones violating the ETH, and discuss their robustness to SUSY-violating perturbations. Our work suggests a generic mechanism to stabilize quantum many-body scars in lattice models in arbitrary dimensions.
Phytochemical Screening and Evaluation of Antidiabetic Activity of the Marine Microalgae: Nannochloropsis Sp.

Published: October 2020

Diabetes  mellitus  is  a  metabolic  disorder  and  is  one  of  the  major  challenges  on  health      of  people  all  over  the  world.  The phytochemicals  of  various  marine  algae  are  found  to  possess  antioxidant,  anti-inflammatory  and  anti-diabetic  properties.  Microalgae  are photosynthetic  organisms  that produce  oxygen  and are capable  of producing  beneficial  secondary  metabolites.  The bioactive  metabolites  like pigments,  phenolics,  amino  acids,  polyunsaturated  fatty acids  etc. produced  by them have a positive  effect  on human  health.   In the present investigation,  the  marine  microalgae  Nannochloropsis  sp.  was  screened  for  phytochemicals  qualitatively  and  quantitatively.  The  evaluation  of antidiabetic activity was determined against the enzymes such as alpha amylase and alpha glucosidase. The extracts were prepared in five different solvents  such as petroleum  ether, aqueous,  isopropanol,  methanol  and ethyl  acetate.  The qualitative  analysis  for  phytochemicals  showed  the presence of alkaloids, phenols, flavonoids, carbohydrates, proteins, cardiac glycosides, sterols, coumarin and tannins. The maximum total phenolic, flavonoid and sterol content was present in ethyl acetate extract of Nannochloropsis  sp. and the values are found to be 42.17 ± 0.12mg GAE/g, 60.23 ± 0.09 mg QE/g, 55.34 ± 0.07 mg cholesterol/g of extract respectively. The ethyl acetate extract showed highest inhibitory effect of 78.52 ±0.56 % (IC50 121.96 µg/ml) on α-amylase and 80.42 ± 0.13 % (IC 50 178.53µg/ml) on α-glucosidase enzyme at a concentration of at 1mg/ml which implies  the microalgae  possess  anti-diabetic  property.  The  results  indicate  that  the phytochemicals  present  in the microalgae  contribute  the antidiabetic activity. Hence Nannochloropsis sp. can be applied in pharmaceuticals for the development of antidiabetic drugs which have the benefits over side effects by the use of synthetic drugs.
The new cases of thelaziosis on the Balkan Peninsula
Authors: Tasic-Otasevic Suzana , Savic Sara , Momcilovic Stefan , Trenkic Marija , Diakou Anastasia
Published: October 2020

Thelazia callipaeda (Spirurida, Thelaziidae), known as oriental eyeworm, is a parasite infesting the eyes of many domestic and wild carnivores which can also cause human infections. Due to the fact that infections by T. callipaeda have been recently spreading through the Balkan Peninsula, the main aims of this mini review are to give a clear and concise overview of the clinical manifestations, diagnosis and treatment of thelasiosis in animals and humans as well as to update epidemiological data about thelaziosis in this area. Clinical manifestations of thelaziosis can vary from subclinical to severe. In both animals and humans, treatment of thelaziosis can be effectively achieved with the removal of the nematodes from the eye under local anesthesia using a cotton swab or fine forceps. In the treatment of animals, antiparasitic drugs should be used supplementarily to the mechanical removal of parasites, while in humans, the topical use of antibiotics is desirable in order to prevent secondary bacterial infection. The growing number of diagnosed thelasiosis cases in dogs in the Balkan Peninsula, and particularly among owned pets in urban areas of Serbia previously considered free of infection, indicates the spread of zoonotic T. callipaeda in the area and in close proximity to humans. Finally, cooperation between veterinarians and physicians is strongly advocated in favour of the development of effective preventive measures and strategies.
Systemizing the Challenges of Auditing Blockchain-Based Assets
Authors: Pimentel Erica , Boulianne Emilio , Eskandari Shayan , Clark Jeremy
Published: October 2020

Presently, auditing firms are hesitant to accept mandates from companies that hold a significant amount of cryptoassets, primarily because the blockchain sector introduces novel, technically sophisticated, and risky propositions that auditors are unequipped to handle. Abrupt recusals by auditors operating in this sector have led to several enterprises being placed on cease trade by securities regulators for failure to produce audited financial statements on time, thus impeding these companies from raising capital and bringing new investments to fund innovation in this space. Through an iterative process of interviews with senior accounting professionals, structured brainstorming among a multidisciplinary team of accountants and blockchain experts, and a focus group with experienced auditors, we critically analyze the purported roadblocks to auditing blockchain firms and map them to traditional auditing practices. We urge auditors to reconsider their resistance to the blockchain sector by demonstrating that providing an audit opinion is challenging but not insurmountable.
Cyber Supply Chain Risk Management: Toward an Understanding of the Antecedents to Demand for Assurance
Authors: Hampton Clark , Sutton Steve G. , Arnold Vicky , Khazanchi Deepak
Published: October 2020

Recognizing the need for effective cyber risk management processes across the supply chain, the AICPA issued a new SOC in March 2020 for assuring cyber supply chain risk management (C-SCRM) processes. This study examines supply chain relationship factors and cyber risk issues to better understand the demand for C-SCRM assurance. Resource-Advantage Theory of Competition provides the conceptual foundation for assessing the dual drivers of relationship building and cyber risk management on demand for assurance. We use a field survey to collect data from 205 professionals enabling evaluation of the complex relationships in the theoretical model. Results support all hypotheses, provide satisfactory model fit, and support the underlying theory. Trust and cyber supply chain risk both positively influence demand for assurance over C-SCRM processes. This study expands the literature on cyber assurance by auditors and elaborates on overall supply chain processes that help drive value from auditors providing such assurance.

Students' critical thinking skills are still not optimal. One of the reasons is the use of teaching materials in the form of student worksheets that are not yet in line with the good student worksheet structure, do not yet contain the STEM approach, and critical thinking indicators have not been clearly illustrated in the student worksheet. The purpose of this study is to determine the validity of the LKPD, determine the practicality and effectiveness of using student worksheet Physics based on the STEM approach that can improve students' critical thinking. This type of research is research and development (R&D) using the Borg & Gall model which consists of the initial research and information gathering stage, planning, developing the initial product format, and initial trials. As the object of research is the Physics student worksheet based on the STEM approach. Data collection instruments used were expert validation sheets, practicality test sheets, and effectiveness test sheets. The effectiveness test uses an assessment sheet of learning outcomes tests and observation sheets of students' critical thinking. The data analysis technique used is the analysis of the validity of the Physics student worksheet, the practicality analysis of the use of the Physics student worksheet, and the effectiveness analysis of the use of the Physics student worksheet. Based on the analysis of the data that has been done, two research results can be put forward. First, the average value of the validity of the Physics student worksheet based on the STEM approach is 0.88 and this value is included in the valid category. Second, the average value of the practicality test for the use of Physics student worksheet by teachers and students respectively 91.44 and 84.14. This value shows the Physics student worksheet is in the category of very practical. Besides that, the use of Physics student worksheet based on the STEM approach is effective to improve students' critical thinking

The press is an organization for disseminating information through mass media, the more information received, the greater the responsibility required. In carrying out its functions, rights, obligations and role, the press is demanded to be open to the public about a news that is raised. To carry out good journalistic activities requires a journalistic code of ethics. The code of ethics established by the Press Council is a basic guideline / reference in carrying out journalistic activities. This regulation makes the direction for the press to continue in accordance with the rules, even though accessing news now is not only through the mass media such as television. Television is part of the mainstream media, despite the convergence of media, the audience still believes that journalistic news on television can be trusted with the truth and credibility of the news content. This study uses descriptive qualitative research methods to analyze in detail the problems that are formulated. The purpose of this research is to find out how the application of the code of ethics in the production of television news on GTV.

The major energy sources that human are relying on are fossil fuel and it is exhausted day by day. Furthermore, exploition and usage of fossil fuel also bring in many negative impacts on environmental polution. Solid oxide fuel cell (SOFC) has been considerred as a potential solution for such environmental and energy problems. Seeking a facile, cost and time saving process to synthesize Ba doped LaMnO3 is very important for development of SOFC applications because it helps to reduce the cost of comercial SOFC. LaMnO3 doped with Ba is more cost effective than Sr doped LaMnO3 because less rare earth elements are used. At the same time, its conductivity is still good enough with an appropriate thermal expansion matched with those of other parts of SOFC based on ytrium stabilized zirconia (YSZ).

In this paper, Ba doped LaMnO3 nanoparticles (LBMO), a promissing material for making cathode of SOFC, were prepared by microwave combustion method. This material has many advantages.  Effect of the amount fuel in the combustion reaction on the products was studied by various methods such as: X-ray diffraction measurement, scanning electron microscopy, energy dispersive X-ray spectroscopy. The results showed that each doping rate requires an appropriate amount of fuel to obtain pure and crystalline product. The obtained LBMO nanoparticles are crystallined in hexagonal phase at doping ratio of 0.2 and orthohombic phase at doping ratio of equal or larger than 0.3.

Coronavirus disease 2019 (COVID-19) has been recognized as a global threat, and several studies are being conducted using various mathematical models to predict the probable evolution of this epidemic. The main objective of this study is to apply AutoRegressive Integrated Moving Average (ARIMA) model with the objective of monitoring and short-term forecasting the total confirmed new cases per day all over the world. The data are extracted from daily report of World Health Organization from 21st January 2020 to 16th March 2020. Akaike’s Information Criterion (AIC) and Ljung-Box test were used to evaluate the constructed models. To assess the validity of the proposed model, the Mean Absolute Percentage Error (MAPE) and Root Mean Square Error (RMSE) between the observed and fitted of COVID-19 total confirmed new cases was calculated. Finally, we applied “forecast” package in R software and the fitted ARIMA model to predict the infections of COVID-19. We found that the ARIMA (1, 2, 1) model was able to describe and predict the epidemiological trend of the disease of COVID-19. The MAPE and RMSE for the training set and validation set respectively, which we found was reasonable for use in the forecast. Furthermore, the model also provided forecast total confirmed new cases for the following days. ARIMA model applied to COVID-19 confirmed cases data are an important tool for COVID-19 surveillance all over the world. This study shows that accurate forecasting of the COVID-19 trend is possible using an ARIMA model. Unless strict infection management and control are taken, our findings indicate the potential of COVID-19 to cause greater outbreak all over the world.
