Public Opinions and Concerns Regarding the Canadian Prime Minister’s Daily COVID-19 Briefing: Longitudinal Study of YouTube Comments Using Machine Learning Techniques (Preprint)
Authors: Zheng Chengda , Xue Jia , Sun Yumin , Zhu Tingshao
Published: August 2020

BACKGROUND

During the COVID-19 pandemic in Canada, Prime Minister Justin Trudeau provided updates on the novel coronavirus and the government’s responses to the pandemic in his daily briefings from March 13 to May 22, 2020, delivered on the official Canadian Broadcasting Corporation (CBC) YouTube channel.

OBJECTIVE

The aim of this study was to examine comments on Canadian Prime Minister Trudeau’s COVID-19 daily briefings by YouTube users and track these comments to extract the changing dynamics of the opinions and concerns of the public over time.

METHODS

We used machine learning techniques to longitudinally analyze a total of 46,732 English YouTube comments that were retrieved from 57 videos of Prime Minister Trudeau’s COVID-19 daily briefings from March 13 to May 22, 2020. A natural language processing model, latent Dirichlet allocation, was used to choose salient topics among the sampled comments for each of the 57 videos. Thematic analysis was used to classify and summarize these salient topics into different prominent themes.

RESULTS

We found 11 prominent themes, including strict border measures, public responses to Prime Minister Trudeau’s policies, essential work and frontline workers, individuals’ financial challenges, rental and mortgage subsidies, quarantine, government financial aid for enterprises and individuals, personal protective equipment, Canada and China’s relationship, vaccines, and reopening.

CONCLUSIONS

This study is the first to longitudinally investigate public discourse and concerns related to Prime Minister Trudeau’s daily COVID-19 briefings in Canada. This study contributes to establishing a real-time feedback loop between the public and public health officials on social media. Hearing and reacting to real concerns from the public can enhance trust between the government and the public to prepare for future health emergencies.
Association of Electronic Health Record Vendors With Hospital Financial and Quality Performance: Retrospective Data Analysis (Preprint)
Authors: Beauvais Bradley , Kruse Clemens Scott , Fulton Lawrence , Shanmugam Ramalingam , Ramamonjiarivelo Zo , Brooks Matthew
Published: August 2020

BACKGROUND

Electronic health records (EHRs) are a central feature of care delivery in acute care hospitals; however, the financial and quality outcomes associated with system performance remain unclear.

OBJECTIVE

In this study, we aimed to evaluate the association between the top 3 EHR vendors and measures of hospital financial and quality performance.

METHODS

This study evaluated 2667 hospitals with Cerner, Epic, or Meditech as their primary EHR and considered their performance with regard to net income, Hospital Value–Based Purchasing Total Performance Score (TPS), and the unweighted subdomains of efficiency and cost reduction; clinical care; patient- and caregiver-centered experience; and patient safety. We hypothesized that there would be a difference among the 3 vendors for each measure.

RESULTS

None of the EHR systems were associated with a statistically significant financial relationship in our study. Epic was positively associated with TPS outcomes (R2=23.6%; β=.0159, SE 0.0079; P=.04) and higher patient perceptions of quality (R2=29.3%; β=.0292, SE 0.0099; P=.003) but was negatively associated with patient safety quality scores (R2=24.3%; β=−.0221, SE 0.0102; P=.03). Cerner and Epic were positively associated with improved efficiency (R2=31.9%; Cerner: β=.0330, SE 0.0135, P=.01; Epic: β=.0465, SE 0.0133, P<.001). Finally, all 3 vendors were associated with positive performance in the clinical care domain (Epic: β=.0388, SE 0.0122, P=.002; Cerner: β=.0283, SE 0.0124, P=.02; Meditech: β=.0273, SE 0.0123, P=.03) but with low explanatory power (R2=4.2%).

CONCLUSIONS

The results of this study provide evidence of a difference in clinical outcome performance among the top 3 EHR vendors and may serve as supportive evidence for health care leaders to target future capital investments to improve health care delivery.

Published: August 2020

BACKGROUND

The outbreak of novel Coronavirus or COVID-19 was reported as early as December 2019 from Wuhan, Hubei Province in China. Since then the disease swiftly spread to infect the world and become one of the most infectious pandemic to hit mankind.

OBJECTIVE

To curtail its pestilence, the Government of India evacuated 647 nationals (including seven Maldivian citizens) from Wuhan, China on the 1st and 2nd February 2020. Retrospective data analysis was done.

METHODS

The evacuees were to be quarantined at two different military camps after arrival. 406 nationals (including seven Maldivian citizens) were kept at Indo-Tibetan Border Police (ITBP) Chhawla Camp while others were sheltered at another military base camp.

RESULTS

During their stay at ITBP the evacuees were tested negative. After 14 days of quarantine they were discharged from the facility. The ITBP facility is unique as It was a first such public health event related to the disease and the preparation time and resources provided were constrained.

CONCLUSIONS

The National Centre for Disease Control in collaboration with ITBP took many initiatives for infection prevention at the site and established the quarantine facility with limited resources.
The manuscript may serve as guidance document to establish quarantine facilities in resource-constrained countries.

Investigation of the Stochastic Choice under Risk using Experimental Data
Authors: Permana Yudistira , Van Empel Giovanni , Pradiptyo Rimawan
Published: August 2020

This paper extends the analysis of the data from the experiment undertaken by Pradiptyo et al. (2015), to help explain the subjects’ behaviour when making decisions under risk. This study specifically investigates the relative empirical performance of the two general models of the stochastic choice: the random utility model (RUM) and the random preference model (RPM) where this paper specifies these models using two preference functionals, expected utility (EU) and rank-dependent expected utility (RDEU). The parameters are estimated in each model using a maximum likelihood technique and run a horse-race using the goodness-of-fit between the models. The results show that the RUM better explains the subjects’ behaviour in the experiment. Additionally, the RDEU fits better than the EU for modelling the stochastic choice.

Authors: Triyono Sulis
Published: August 2020

This study aims to describe: (1) objektive und subjektive constructions in German sentences, (2) meanings of objektive und subjektive in German sentences, and (3) equivalences of objektive und subjektive in German sentences in Indonesian.This was a qualitative descriptive study. The objects of the research data were lingual units of modality constructions with objective and subjective meanings in both German phrases and sentences. The subjects of the data were modal verbs in German sentences. The data sources were the magazine NADI Indonesia Deutsch Edisi I/No. 16 Tahun 2012, Edisi I/No. 17 Tahun 2013, and Edisi II/No. 18 Tahun 2013. The data were collected by means of reading and noting techniques and analyzed by means of the translational, equivalent, and distributional techniques. The data validity was assessed through the semantic validity and the inter-rater and intra-rater techniques.The research findings are as follows. (1) the objektive construction in German is S - Inf+Modalverb and the subjektive construction is S+Inf – Modalverb. (2) Meanings of objektive are those which are loose in nature because because lexical elements of modality can reveal utterance contents while meanings of subjektive are those outside lexical elements because they are affected by speakers’ subjective intentions. (3) The equivalences of objektive und subjektive in German sentences in Indonesian are in the form können appearing 107 times, equivalent to meanings of dapat, bisa, ada, menjadi, berhasil, mampu, meraih, terdiri, sungguh, and makna zero. Dürfen (8) are equivalent to meanings of dapat, boleh, and makna zero. Modalverb sollen (27) are equivalent to meanings of harus, akan, bisa, seharusnya, perlu, dan makna zero. Wollen (3) are equivalent to meanings of ingin, terus terang, and makna zero. Müssen (31) are equivalent to meanings of harus, dapat, bisa, and makna zero. Möchten (16) are equivalent to meanings of ingin, berminat, perlu, and makna zero.
The Aesthetics of a Three-Way Pattern: The Musical Concept of Talempong Renjeang and The Social System of The People of Luhak Nan Tigo Minangkabau
Authors: Sastra Andar Indra
Published: August 2020

The goal of this article is to discuss the aesthetics of the three-way pattern in the musical concept of  talempong renjeang (tenteng) and the social system of the people of Luhak Nan Tigo Minangkabau. The musical concept of talempong renjeang is formed by 3 (three) pairs of  talempong: talempong Jantan, talempong Paningkah, and talempong Pangawinan. As the ‘leader’, the talempong Jantan maintains the consistency and integrity of the theme and danyuik (tempo) of the playing, the talempong Paningkah follows the lead of the talempong Jantan using different playing motifs, and the talempong Pangawinan has the role and authority to make the guguah (melody) of the talempong complete – creating a three-way aesthetical pattern. The social system of the people of LuhakNan Tigo was created by three legendary figures, namely Dt. Katumangguangan, Dt. Parpatiah Nan Sabatang, and Dt. Nan Sakelap Dunia (RajoBabandiang). From these three figures, the concept of tali tigo sapilin, tungku nan tigo sajarangan was born (a philosophy of harmony). The method used for the research is based on qualitative data which was collected through observation, interviews, and documentation. The data analysis focuses the talempong renjeang as a musical and the social system of the Minangkabau community which began with two legendary Minangkabau figures. The results of the study show that talempong as a musical system corresponds to, or synchronizes with, the social concept of the people of Luhak Nan Tigo Minangkabau.
Common Discourse Patterns of Cross-diciplinary Research Article Abstracts in English
Authors: Hardjanto Tofan Dwi
Published: August 2020

Because of its important role in the advancement of science, attempts have been made to investigate research article abstracts in terms of both their discourse patterning and their linguistic characteristics. This research is an attempt to examine their rhetorical patterning. More specifically, it addresses the questions what common discourse patterns research article abstracts have and whether abstracts from different disciplines show different patterns. The research corpus contained 50 research article abstracts collected from five international journals published in the fields of biology, engineering, linguistics, medicine and physics. The data were analyzed using a four-move abstract structure developed by Hardjanto (1997). The results showed that Moves 1, 3 and 4 were found in most abstracts, and were, therefore, considered as obligatory moves in the abstracts. The most common pattern was found to be a pattern containing all the four moves in the order of 1-2-3-4, especially in abstracts from medicine and linguistics. Another common pattern was a 1-3-4 pattern, found especially in abstracts from biology and physics, whereas abstracts from engineering did not show any preference for a specific pattern even though 40% of them had a 1-2-3-4 pattern. These results suggest that there is a significant disciplinary variation in English research article abstract patterning.
Integration of French Lexicons in New Caledonian Javanese
Authors: Subiyantoro Subiyantoro , Marsono Marsono , Udasmoro Wening
Published: August 2020

One of the peculiarities of New Caledonian is its French nuance, especially on the many French lexicons that either have integrated in the Javanese variant or are only borrowed. This study tries to answer the questions of what underlies the use of the French lexicons and how these lexicons integrated in New Caledonian Javanese. The data for this study were obtained through speech recordings as well as live interviews with a number of representative informants in New Caledonia. The data were collected through a qualitative manner in February 2013. Theories on language contacts, in particular with regards to loanwords, were implemented to analyze the data. The findings of this study indicate that the use of the French lexicons are caused by, firstly, the nonexistence of their equivalents in the recipient language (Javanese), secondly, Javanese speakers’ motivation to distinguish themselves from other speakers, and the tendency of the Javanese to find the practical and easier way in dealing with the French lexicons.
Packaging Differences of News Content on Title

Published: August 2020

This study investigates anything that underlie the differences of the variation on the packaging variation of the news content on the title that is based on the topicalization, the materials of news title writing, clarity and complexity of the news content, reference shifting from the title to the body of the news, roles of the mediator and the source of the news, maintaining the local value of the news, comparison between the news content on the prior text, and the ideology of the news. The analysis was conducted through pragmatic identity method, referential identity method, and traditional identity method. The data were analyzed by employing discourse approach (: micro-structure), especially the connectivity between the title to the body of the news.There are many things that underlie the differences of news content packaging on the straight news. From the structure of the news element, it can be found the several topicalizations such as the topicalization of what, who, where, when, cause, manner, or the combination of two or more elements of the news. A clear and complex package of a news content on the title gives an ease to the reader to understand the news content. However, in a package which does not put the clear reference on the title, the readers are suggested to continue to read the body of the news. Then, in a package which put the source of the news and its utterance on the title, the journalist tries to enclose the relation of the reader to the source of the news. Meanwhile, in a package which put the journalist as the mediator, the readers are invited to understand the content of the news based on their understanding and interpretation. As a commodity, any packages are utilized so that the news papers are not left behind by the readers. In a news which contains local value, the local utterances are maintained for the readers from other area to learn. Finally, in the package of the news content, the selection of the news topics becomes the ideologies which are harmonized with their vision-mission.
Principles of Textual Rhetoric in CakCuk Discourse
Authors: Subiyatningsih Foriyani
Published: August 2020

This research aims to study how the creator of CakCuk creates language based on the principles and maxims of textual rhetoric in CakCuk designs. The data was collected using a method of observation, with a basic technique of recording followed by a technique of note-taking. The data analysis used a method of distribution, comparison, and contextual identity. The results of this study show that CakCuk discourse is a product of the language creativity of its creator through the utilization of principles or maxims of textual rhetoric. The key to this creativity is the creator’s ability to use maxims in order to achieve efficiency, clarity, effectiveness, and attractiveness in the text. The motivation underlying the choice of principles/maxims is: (i) the principle of processability in order to determine the main focus and weighting of the text; (ii) the principle of clarity in order to make the message clear; (iii) the principle of economy in order to keep the text as short as possible; (iv) the principle of expressiveness in order to make the text effective.

Book Review. Feeling Gender: A Generational and Psychological Approach
Authors: Rudy Rudy
Published: August 2020

As one of the phenomenal issues in the world, gender has always been an unfinished argument among experts, researchers, and academicians. With the growth of science and technology and the development of media in the 20th century, there have been many changes in perceiving gender. Topic on gender which was not widely discussed in academic forum has become an important topic nowadays. Studies and researches on gender have been in great progress since 1990s when more and more experts such as Judith Butler, Donna Haraway, etc. began to publish their writing on gender and sexuality. People started learning more about this issue.A common thing that people may understand is that there are biological and social factor which give a significant impact to gender categorizations (Fagot et al, 1997: 2). However, gender issues remain arguable topics from time to time. Era changes and one generation is replaced by another younger generations. From this condition, Harriet Bjerrum Nielsen, the professor at the Centre for Gender Research at the University of Oslo, Norway has shown her serious concern on how feelings of gender can change from one generation to another by observing the how men and women from some generations feel about their relationships toward their parents in order to reveal what gender really is to them. Therefore, this study incorporates a generational and psychological approach for analysis.
"Are My Songs Literature?": A Postmodern Appraisal of Bob Dylan's American Popular Music Culture
Authors: Alkhayat Marwa Essam Eldin
Published: August 2020

The current study is a postmodern appraisal of Bob Dylan’s artistic career and vocal gestures to examine the way melody in popular music works in relation to speech and singing, the grand and the ordinary. It historicizes Bob Dylan’s protest music of the 1960s within the paradigm of folk music culture. Dylan’s music is full of riffs, blues sequences, and pentatonic melodies—all heavily part and parcel of blues, folk, gospel, and country music. It is the music that dwells on the pleasures of repetition, of circularity, and of the recurring familiar tune integrated within Dylanesque poetics of rhyme delivered with his idiosyncratic, deep and intense range of voices. Dylan is the official son of the legacies of social, communal, and ritual music-making that mirrors contemporary pop and rock back to folk and blues, street-sung broadsides and work songs, the melodies of medieval troubadours, and the blessed rhythms of Christianity and Judaism. The study is an attempt to illustrate how musicology and ethnomusicology in particular can contribute to understanding Dylan as a ‘performing artist’ within the postmodern paradigm. Thus, the study seeks to establish Dylan as a phenomenal, prolific postmodernist artist, as well as an anarchist. The power and originality of Dylan’s music constitute a prima facie case that his performances should be considered postmodernist art.
Misrepresentation of Science and Expertise: Reflecting on Half a Century of Indonesian Anthropology
Authors: Abdullah Irwan
Published: August 2020

Indonesian anthropology was founded in 1957 and developed since then in various universities. After more than fifty years of inhabiting these lecture halls, anthropology’s orientation as a science has transformed from a discipline that bestows on graduates the ability to think into one in which graduates are prepared for a career of conductingfield research ordered by others. This article reflects on the shifts that have occurred in anthropology, focusing on three of the field’s central figures in Indonesia: Koentjaraningrat, Masri Singarimbun, and Parsudi Suparlan. During the lives of these three pioneers, anthropology playeda central role in critically evaluating humanitarian projects, and as such anthropologists frequently served to protect the weak and marginal. Anthropologists were on the frontlines of every discussion regarding the future of the nation, enabling anthropological perspectives to be accommodated in policy. Today, anthropologists seem locked into their own academic spaces. The results of anthropological field research are often said to provide unique and interesting—but irrelevant—stories. This article recommends a fundamental transformation in the curriculum, allowing the politics of science to be reconsidered and reformulated to ensure anthropology maintains a central role in resolving future humanitarian problems.
Contestation in Gamelan Making Rituals: Tensions between Old and New Understandings
Authors: Handayani Andri , Swazey Kelli
Published: August 2020

Performing ritual before making gamelan as one of stages of producing gamelan orchestra has changed. The decision of gamelan masters to perform ritual is affected by their worldview, socio-religious and economic changes in their surroundings. This research aims to identify contestation in gamelan making rituals especially the tensions that occur between old and new understanding of gamelan masters. The study was conducted from March 2013 to April 2015. Semi-structured interview was applied to 6 out of 10 gamelan masters in Wirun Village, Sukoharjo District, Central Java. The result finds that gamelan masters apply strategies such as purification, negotiation and commercialization to adapt to the changes in Wirun. These strategies occur based on the understanding of old and younger generation of gamelan masters in Wirun. Purification can be defined as gamelan masters attempt to purify their religious principle from other external influence. There are two types of purification conducted by gamelan masters; purification of Javanese belief and purification of Islamic teachings. Negotiation hitherto is a way for gamelan masters to perceive their religious perspective and Javanese traditions flexibly. While, commercialization is taken by gamelan masters who only perceive gamelan as an industrial commodity and who prioritize the market value disregarding religious values in making the gamelan. The strategies serve to allow gamelan masters to sustain their identity as gamelan craftsmen.

Extended Aging and Marbling Class Effects on Color Stability of Beef Longissimus lumborum, Gluteus medius, and Biceps femoris Steaks
Authors: King D. Andy , Shackelford Steven D. , Cushman Robert A. , Wheeler Tommy L.
Published: August 2020

Postmortem aging improves palatability of various muscles, especially those from lower quality grades. This study evaluated postmortem aging and marbling class effects on the color stability of longissimus lumborum, gluteus medius, and biceps femoris steaks. Carcasses were selected at grading to have Lower Small (Small00 to Small50; n = 50) or Upper Slight (Slight50 to Slight90; n = 50) marbling scores. Strip loin and top sirloin subprimals from each carcass side were assigned to aging treatments (14, 21, 28, or 35 d) in an incomplete block arrangement. After aging, subprimals were cut into longissimus lumborum, gluteus medius, and biceps femoris steaks, respectively. Steaks were placed in a simulated retail display for 11 d. Changes in redness (a* and hue angle) were much slower and less extensive (P < 0.001) in longissimus lumborum steaks than in gluteus medius steaks, which had slightly slower and less extensive (P < 0.01) redness changes than biceps femoris. Increasing aging time increased (P < 0.001) the rate and extent of overall color change (ΔE) during simulated retail display. Steaks from Lower Small carcasses had higher (P < 0.01) L* values than steaks from Upper Slight carcasses at 14, 28, and 35 d postmortem. In steaks from Upper Slight carcasses, L* values were lower (P < 0.01) in steaks aged for 28 d compared to other aging times. In steaks from Lower Small carcasses, L* values were highest (P < 0.001) when aged for 14 d. Increased aging time generally decreased (P < 0.05) a*, b*, and chroma values. However, within each aging time, only b* values of steaks aged for 35 d differed (P = 0.01) with regard to marbling class. Results indicate that increasing aging time decreased color life of beef muscles, and that marbling class had minimal impact on lean color stability.
El Servicio de Administración Tributaria y las multinacionales en México: un juego de señalización de la evasión fiscal
Authors: Rosas Roodríguez Beatriz , Demmler Michael
Published: August 2020

Objetivo: analizar las regulaciones y multas de precios de transferencia en México desde el enfoque de la teoría de juegos.Diseño metodológico: se utilizan dos modelos de señalización con información incompleta entre el Servicio de Administración Tributaria y las empresas multinacionales, en ellos las multinacionales tienen información privada que no comparten con la autoridad fiscal.      Resultados: en el primer modelo se encuentran dos equilibrios de agrupación, uno en el que la multinacional reporta ingresos altos y la administración tributaria nunca audita, mientras el segundo se basa en que la multinacional reporta ingresos bajos y la autoridad fiscal audita con cierta probabilidad.Limitaciones de la investigación: debido a que no se cuenta con información precisa del porcentaje de multinacionales que evaden impuestos, el modelo se realizó con la información más reciente donde se supone que un 20 % de las personas morales evaden impuestos.Hallazgos: se encuentra que un bajo nivel de auditorías no ayuda a reducir la evasión, un incremento en las multas incentiva las auditorías y que, mientras las multas variables continúen aumentando, las multinacionales no tendrán incentivos para evadir.
Stochastic gradient descent for hybrid quantum-classical optimization
Authors: Sweke Ryan , Wilde Frederik , Meyer Johannes , Schuld Maria , Faehrmann Paul K. , Meynard-Piganeau Barthélémy , Eisert Jens
Published: August 2020

Within the context of hybrid quantum-classical optimization, gradient descent based optimizers typically require the evaluation of expectation values with respect to the outcome of parameterized quantum circuits. In this work, we explore the consequences of the prior observation that estimation of these quantities on quantum hardware results in a form ofstochasticgradient descent optimization. We formalize this notion, which allows us to show that in many relevant cases, including VQE, QAOA and certain quantum classifiers, estimating expectation values withkmeasurement outcomes results in optimization algorithms whose convergence properties can be rigorously well understood, for any value ofk. In fact, even using single measurement outcomes for the estimation of expectation values is sufficient. Moreover, in many settings the required gradients can be expressed as linear combinations of expectation values -- originating, e.g., from a sum over local terms of a Hamiltonian, a parameter shift rule, or a sum over data-set instances -- and we show that in these casesk-shot expectation value estimation can be combined with sampling over terms of the linear combination, to obtain ``doubly stochastic'' gradient descent optimizers. For all algorithms we prove convergence guarantees, providing a framework for the derivation of rigorous optimization results in the context of near-term quantum devices. Additionally, we explore numerically these methods on benchmark VQE, QAOA and quantum-enhanced machine learning tasks and show that treating the stochastic settings as hyper-parameters allows for state-of-the-art results with significantly fewer circuit executions and measurements.

El estudio se realizó desde octubre de 2010 hasta abril de 2011 en el bosque sobre arena blanca, localmente conocido como varillal, en los siguientes tipos: alto húmedo (VAH), alto seco (VAS), bajo húmedo (VBH) y bajo seco (VBS) al interior de la Reserva Nacional Allpahuayo Mishana, cerca del km 24,6 y 28,0 de la carretera Iquitos – Nauta, Loreto, Perú. El objetivo fue conocer la riqueza, abundancia, dominancia, diversidad y similitud de la comunidad de escarabajos coprófagos (Scarabaeinae) en los diferentes tipos de varillales utilizando trampas de caídas cebadas con heces humanas. Se colectaron 6 241 individuos pertenecientes a 16 géneros y 42 especies. La riqueza y medida de entropía o diversidad fueron mayores en VAH y VAS, pero mayor dominancia hubo en VBS y VBH. Las especies y abundancias entre los varillales altos y bajos fueron diferentes, así como entre los varillales bajos. Las especies Canthidium aff. cupreum, Ateuchus sp., Dichotomius lucasi y Onthophagus haematopus prefieren a los varillales alto seco y húmedo mientras que Scybalocanthon sp. prefiere a los varillales bajos. Los escarabajos coprófagos deben de ser utilizados como indicadores de cambios en la estructura de la vegetación

El Corocoro Escarlata (Eudocimus ruber) está considerado para el Perú como una especie divagante, errante o ambas; su avistamiento ocurre ocasionalmente y no es parte de la avifauna habitual. En esta nota documentamos la presencia de Eudocimus ruber en Loreto, y se actualiza su ocurrencia en el Perú. Adicionalmente confirmamos que algunas especies de aves aparecen en la zona aledaña a la ciudad de Iquitos u otras áreas de Loreto como consecuencia de los nuevos espacios abiertos que son generados por la actividad antropogénica.

RESUMOO artigo tem o objetivo analisar a relação entre hipermodernidade e consumo, com ênfase na oferta irresponsável do crédito e no superendividamento. Para tanto, por intermédio de estudo bibliográfico, analisa o problema do desenvolvimento da hipermodernidade com a busca da felicidade associada ao consumo na perspectiva de uma sociedade líquida, além de como a cultura do ter que estimula o superendividamento. Por fim, chega-se o entendimento de que o consumidor tem que ser um elemento protagonista nas relações de consumo com o escopo de garantir a autonomia da vontade no ato negocial.PALAVRAS-CHAVEHipermodernidade. Consumidor. Autonomia da Vontade. Superendividamento. ABSTRACTThe present article aims to analyze the connection between hypermodernity and consumption, with an emphasis on the irresponsible credit supply and over-indebtedness. Therefore, through a bibliographical study, it analyzes the problem of the development of hypermodernity with the search for happiness associated with consumption in the perspective of a liquid society, in addition to how the culture of “owning” stimulates super indebtedness. Finally, it arrives at the understanding that the consumer has to be a protagonist element in consumer relations with the scope of guaranteeing the autonomy of the will in the negotiating act.KEYWORDSHypermodernity.

Trastorno de estrés postraumático en menores internados por maltrato en cinco instituciones ICBF- Pereira
Authors: Parra Jhon Jairo Trejos , García Osorio Claudia Lorena
Published: August 2020

Introducción. El trastorno de estrés postraumático (TEPT) aparece después de la exposición a un evento amenazante e incluye síntomas de evitación e intrusión del recuerdo, hiper-alerta e hiperreactividad , alteraciones negativas cognitivas y alteraciones en el estado de ánimo. Puede aparecer en más del 50% de los niños afectados por desastres de origen natural o humano, como el maltrato, afectando gravemente su calidad de vida presente y futura.
Objetivo: Determinar la prevalencia de TEPT en niños internados por maltrato en cinco instituciones de Pereira vinculadas al ICBF.
Materiales y métodos. Se construyó, validó y utilizó una escala graduada a partir de los criterios sintomáticos del DSM-5 de TEPT adaptada a población escolar. Se aplicó mediante entrevista personal, previa educación lúdica a los niños sobre los conceptos pertinentes.
Resultados y conclusiones. La población de estudio fueron 46 hombres y 47 mujeres institucionalizados en el ICBF, con una media de edad de 11.6 (desviación estándar 2.0) y un tiempo de estadía máximo en el rango inferior de menos de 6 meses con tendencia a la baja y una escolaridad por debajo de lo esperado para la edad . La causa principal de ingreso fue por maltrato intrafamiliar con un 49% , seguido por el abandono o pobreza extrema con un 41%. En cuanto a los criterios para TEPT, el 60 (64.5%) de los menores de edad institucionalizados por vulneración de derechos, cumplían todos los criterios y el 8 (8.6%) cumplían todos menos un criterio sintomático (TEPT subclínico), este alto porcentaje concuerda con la literatura mundial y nacional. Finalmente, el 21.5% no presentaban síntomas y el 5.4% no habían estado expuestos a eventos traumáticos. Los diferentes criterios sintomáticos tenían un nivel similar de intensidad.

Introducción: Durante el alta hospitalaria es importante que el enfermero identifique los cuidados que requiere el paciente, permitiéndole guiar intervenciones mediante el plan de alta que fomenta el autocuidado, enfocado a necesidades específicas de cada persona, para prevenir complicaciones y disminuir reingresos.

Objetivo: Evaluar la ejecución del plan de alta por los profesionales de enfermería en los servicios de medicina interna y quirúrgicas del Hospital San José, Popayán durante el año 2017.

Materiales y métodos: Estudio de tipo cuantitativo, diseño descriptivo y transversal. La población conformada por los enfermeros de los servicios de medicina interna y quirúrgicas del Hospital San José y pacientes con alta programada de 24 horas o menos antes del egreso hospitalario.

Resultados: La información se recolectó por medio de un instrumento de valoración realizado a participantes que cumplen con criterios de inclusión. El 94,7% de los pacientes tenían egreso programado, de estos 58,6% recibieron indicaciones en las últimas 48 horas sobre los cuidados en casa y el 100% manifestaron entender las recomendaciones brindadas por el enfermero. Respecto al profesional de enfermería el 100% refiere no conocer alguna metodología para elaborar el plan de alta y el 80% no conoce si en la institución existe un procedimiento de egreso y seguimiento al paciente.

Conclusiones: El plan de alta es un proceso que no se encuentra estandarizado y por lo tanto no es evaluado en la institución, el personal de Enfermería se limita a brindar educación sobre las indicaciones médicas de egreso y no sobre un plan de alta propio de Enfermería.
Efecto de un programa de “exergames” en el equilibrio y la movilidad funcional de personas mayores. Un estudio piloto
Authors: Labra Gómez Fernando Andrés , Mahecha Matsudo Sandra
Published: August 2020

Introducción: Las personas mayores experimentan una menor capacidad para mantener y restablecer el equilibrio durante las actividades físicas. Durante la última década los videojuegos controlados con movimientos de todo el cuerpo, también conocidos como “Exergames”, han ganado popularidad como herramientas para mejorar el equilibrio y la movilidad funcional. El software KineLabs 3D es una serie de minijuegos que utiliza la plataforma Kinect para la rehabilitación de pacientes con secuelas de accidente vascular encefálico y para el entrenamiento de personas mayores. A nuestro conocimiento no hay investigaciones que utilizen este Exergame.

Objetivo: Analizar el efecto de un programa de ejercicios del Exergame KineLabs 3D en el equilibrio y la movilidad funcional en personas institucionalizadas y autovalentes entre los 65 y los 85 años.

Materiales y métodos: Se realiza un estudio piloto, cuantitativo, pre test-post test de un solo grupo de cinco personas que completaron un programa de 24 sesiones, tres veces por semana. Las pruebas clínicas escala de balance de Berg, prueba de alcance funcional, estación de apoyo unipodal y Short Physical Performance Battery fueron utilizadas antes y después del desarrollo del programa para medir el equilibrio y la movilidad funcional.

Resultados: Las personas mayores que participaron en el programa mostraron una diferencia significativa en todas las pruebas clínicas (escala de balance de Berg p=0,0422, prueba de alcance funcional p=0,0431, estación de apoyo unipodal p=0,0422 y Short Physical Performance Battery p=0,0384; p<0,05)

Conclusiones: Un programa de ocho semanas de ejercicios de Exergames en personas autovalentes institucionalizadas mejoró el equilibrio y movilidad funcional.
(RE)SIGNIFICADOS DAS CIÊNCIAS BIOLÓGICAS: ANÁLISE DO PROCESSO DE SEMIOSE DO CONCEITO DE CAMUFLAGEM EM DESENHOS ANIMADOS
Authors: Lucena Paloma Alves Marinho , Perticarrari André
Published: August 2020

Este trabalho busca responder como ocorre a (re)significação de conceitos e termos relacionados a ciência na linguagem da animação, com intuito de evidenciar quais elementos simbólicos os desenhos animados utilizam para representar os conceitos científicos das ciências biológicas. Para tanto, desenvolveu-se uma pesquisa qualitativa em que se realizou análise semiótica de desenhos animados, tais como “Show da Luna”, “Aventuras com os Kratts” e “Natugato”, ancorada na teoria Peirciana. Conjectura-se que a relevância deste estudo provém da possibilidade de compreensão do processo de semiose que ocorre entre os signos analisados (desenhos animados e material acadêmico). Considera-se a possibilidade da utilização dos desenhos animados com temáticas científicas como recurso não formal para a popularização das ciências, que ao receber um olhar crítico, pode ser utilizado como ferramenta pedagógica. De acordo com os resultados, percebeu-se que os episódios analisados podem ser considerados como recurso que apresenta aspectos próprios da ciência, de maneira simples e clara.Observou-se uma ressignifiação da linguagem científica para a do entretenimento, o uso e a presença de alguns símbolos característicos da Biologia em todos os episódios. Além disso, verificou-se que os elementos caracteríticos da animação (som, música, repetição e transição de imagens, zoom-in e zoom-out) são utilizados tanto para marcar as etapas do trabalho científico (elaboração do problema, levantamento de hipoteses, testes e experimentos, possível explicação/solução do problema, conclusão e divulgação das conclusões), quanto na apresentação dos conceitos e fenômenos da Biologia. Em geral os conceitos de Biologia abordados nesses episódios estão em consonância com o material acadêmico comparado.
SOBRE A NATUREZA DA CIÊNCIA: ASSERÇÕES COMENTADAS PARA UMA ARTICULAÇÃO COM A HISTÓRIA DA CIÊNCIA
Authors: Peduzzi Luiz O. Q. , Raicik Anabel Cardoso
Published: August 2020

Um dos objetivos da educação científica, na atualidade, em qualquer nível de ensino, é o de propiciar uma compreensão de natureza da ciência compatível com reflexões filosóficas contemporâneas.Todavia, discussões implícitas sobre a ciência em materiais de ensino não são suficientes para promover um aprendizado significativo e atual do tema. A literatura mostra que é preciso desenvolver estratégias que tornem explícitas certas proposições, ou questionamentos. Em geral, princípios descontextualizados e declarativos, de enunciados sucintos e passíveis de ambiguidade, presentes em listas que reúnem aspectos teoricamente consensuais sobre a natureza da ciência, com frequência são distorcidos e mal compreendidos por estudantes e professores. Nesse sentido, este artigo apresenta uma série de 18 asserções comentadas, que explicitam entre si sobreposições e convergências, assim como divergências, como uma alternativa potencialmente útil para a abordagem de vários aspectos da natureza da ciência e do trabalho científico no ensino. Além disso, contextualiza a gênese dessas proposições, desenvolvidas inicialmente para serem articuladas a um conjunto de textos sobre a história da ciência/física, mas que se mostram igualmente profícuas para um vínculo e contraste com produções históricas da ciência em geral, análises epistemológicas de filmes, séries/vídeos, hipermídias, documentos e narrativas históricas e outras ações que visem uma melhor compreensão e aprofundamento desta temática no universo de estudantes, professores e pesquisadores em formação.
