The narrow land in big cities such as Jakarta, increases the amount of high rise building, especially multi-storey office building. Office building consumes much energy to provide air conditioning to meet the thermal comfort inside the building. On the other hand, the building shape, building envelope, and building orientation to the sun's position are the main factors in building design aspects that affect the amount of cooling load. This study aims to investigate the impact of the aspect ratio or the ratio of the longer dimension of an oblong plan to the shorter, on external heat gain of multi-storey office building. Variables examined include the transparent and solid area of building envelope, the total area of the surface of the building envelope in any orientation, and the volume of the building, as well as the influence of those proportion on the external heat gain. This study uses mathematical calculations to predict the cooling load of the building, particularly external heat gain through the walls, roof and glass, as well as comparative analysis of models studied. The study also aims to generate the design criteria of building form and proportion of multi-storey office buildings envelope with lower external heat gain. In Jakarta climatic conditions, the result on rectangular building plan with aspect ratio of 1 to 4 shows that the external heat gain did not differ significantly, and the smallest heat gain is found on the aspect ratio of 1.8. Results also showed that the greater aspect ratio, the greater reduction of external heat gain obtained by changing the orientation of the longest side facing east-west into the north-south, about 2.79% up to 42.14% on the aspect ratio of 1.1 to 4. In addition, it is known that in same building volume, changing the number of floors from 10 to 50 can improve the external heat gain almost twice.

In the past, Alun-alun is united with the Keraton complex and present in an axis. The physical elements which forms an axis in Alun-alun are the two banyan trees that form the orientation towards the government complex (Keraton). As the development progresses, Alun-alun is revitalized to adjust current cultural conditions and to improve the quality of the Alun-alun's hall as the city's identity. This research aimed to determine the representation of physical elements which formed an axis in Alun-alun towards the government complex. Habraken's theory on the physical order was considered adequate to dissect the physical elements which formed Alun-alun and lead to the conclusion of this research. Matters that needs to be identified to reach the interpretation stage were identifying levels in nominal classes, namely major arteries, roads, building elements, partitioning, furniture, bodies and utensils. The results indicated that the axis of Alun-alun towards the current government complex was indicated by the physical form of locating the furniture in one axis, forming the pathways, the hardening of soil at the main entrance area and the addition of gates inside Alun-alun. The conclusion of this research was that in the past, the axis of Alun-alun towards the government complex was formed by the belief and symbolic meanings of its cultural life. Currently the axis was formed from the physical element of complementary facilities or infrastructure of economic and social activities as a representation of the axis in Alun-alun towards the government complex.

Various influences toward West Sumba traditional house’s morphology are affecting the way its exterior appearance has formed. Despite their exterior uniformity, each of these houses is showing different spatial configuration. Spatial configuration is a product of certain social processes. In other words, different society will produce different spatial configuration. Meanwhile, it is believed that space syntax method could be employed to elaborate objectively particular social phenomenon by examining its spatial configuration. Based on that, this research attempted to identify the genotype in those houses to reveal the social phenomenon occurred. Core and territory are parts of several factors that potentially represent a cultural pattern in certain society. The result revealed that these houses are in fact sharing same spatial patterns. It is strongly indicated by core and territory pattern comparison. Four of the five samples are showing a strong genotype, while the left one is showing a genotype differences. In addition, there is a fact that this house with different genotype is located in a village that exposed to modernization.

Environment (external factors) and user attributes (internal factors) affect the user's response to the environment. This study aims to uncover how the quality of the environment in high school as an external factor and student motivation as an internal factor affects the academic performance of the students. The research was conducted with qualitative and quantitative approach. Data were collected by survey using an online questionnaire. From the regression analysis, it was found that the dimensions of external factors of "classroom order", "social interaction and supervision" and "air quality" further increased the effectiveness of student learning rather than internal dimensions of "resilience and capacity building". Meanwhile, the decrease in air quality, noise, and environmental pollution can cause student learning disruption. Based on these findings, it can be concluded that the learning environment plays an important role in shaping the effectiveness of student learning.

Published: January 2021

Various competitiveness reports on tourism have ranked Japan as one of the most visited countries in Asia. Along with South Korea and Singapore, Japan offers many unique traits to the tourists. Since the establishment of “Kihinkai” (lit. Welcome Society), Japan’s first organization to engage with foreign tourists, the country has succeeded in developing various sector of tourism such as heritage sites, nature-based tourism, religious sites, and urban tourism. Tokyo Metropolis, as the capital of Japan, is one of the best examples in urban tourism sector. Hotel occupancy in Tokyo has risen around 80% in the last decade, showing high growth of tourism in the city. The aforementioned growth is supported by many factors, with one of them being the enhancement of tourist attractions. The paper examines Tokyo’s nine most famous tourist attractions specifically at their spatial aspects. The complexity of place, accessibility and the presence of surrounding amenities, as well as the ambience or atmosphere offered by the attractions are the components analyzed to form a set of characteristics that define the character of Tokyo’s tourist attractions. The compiled data can be a precedent study or preliminary guideline for other big cities in Japan or Asia to develop their potential of urban tourism.

The use of atrium in hospital buildings accelerating the patient's healing process and reduce the impression of stress on hospital buildings. However, the presence of the atrium can also pose a fire hazard because it can be a means of spreading smoke quickly. This study determines the effect of atriums in hospital buildings on the level of life safety in the event of a fire. The study was conducted at two hospitals in Bandung and Jakarta, Indonesia. The level of life safety is assessed through the difference between the time needed for the evacuation, referred to as RSET, and the time taken by smoke to cause a critical condition for occupants, called ASET, where RSET must be shorter than ASET. The analysis carried out on two physical configurations: open and closed atrium, and the results of this study showed that with an open atrium, the smoke quickly covered the evacuation route before the evacuation process completed, or ASET<RSET. The fire room door must be closed, and the smoke-barrier must be installed around the atrium to prevent the spread of smoke into patient rooms, thus fulfill the ASET<RSET criteria.
Attitudes Toward Technology and Use of Fall Alert Wearables in Caregiving: Survey Study
Authors: Vollmer Dahlke Deborah , Lee Shinduk , Smith Matthew Lee , Shubert Tiffany , Popovich Stephen , Ory Marcia G
Published: January 2021

Background

Wearable technology for fall alerts among older adult care recipients is one of the more frequently studied areas of technology, given the concerning consequences of falls among this population. Falls are quite prevalent in later life. While there is a growing amount of literature on older adults’ acceptance of technology, less is known about how caregivers’ attitudes toward technology can impact care recipients’ use of such technology.

Objective

The objective of our study was to examine associations between caregivers’ attitudes toward technology for caregiving and care recipients’ use of fall alert wearables.

Methods

This study examined data collected with an online survey from 626 caregivers for adults 50 years and older. Adapted from the technology acceptance model, a structural equation model tested the following prespecified hypotheses: (1) higher perceived usefulness of technologies for caregiving would predict higher perceived value of and greater interest in technologies for caregiving; (2) higher perceived value of technologies for caregiving would predict greater interest in technologies for caregiving; and (3) greater interest in technologies for caregiving would predict greater use of fall alert wearables among care recipients. Additionally, we included demographic factors (eg, caregivers’ and care recipients’ ages) and caregiving context (eg, caregiver type and caregiving situation) as important predictors of care recipients’ use of fall alert wearables.

Results

Of 626 total respondents, 548 (87.5%) with all valid responses were included in this study. Among care recipients, 28% used fall alert wearables. The final model had a good to fair model fit: a confirmatory factor index of 0.93, a standardized root mean square residual of 0.049, and root mean square error of approximation of 0.066. Caregivers’ perceived usefulness of technology was positively associated with their attitudes toward using technology in caregiving (b=.70, P<.001) and interest in using technology for caregiving (b=.22, P=.003). Greater perceived value of using technology in caregiving predicted greater interest in using technology for caregiving (b=.65, P<.001). Greater interest in using technology for caregiving was associated with greater likelihood of care recipients using fall alert wearables (b=.27, P<.001). The caregiver type had the strongest inverse relationship with care recipients’ use of fall alert wearables (unpaid vs paid caregiver) (b=–.33, P<.001).

Conclusions

This study underscores the importance of caregivers’ attitudes in care recipients’ technology use for falls management. Raising awareness and improving perception about technologies for caregiving may help caregivers and care recipients adopt and better utilize technologies that can promote independence and enhance safety.
Disease Concept-Embedding Based on the Self-Supervised Method for Medical Information Extraction from Electronic Health Records and Disease Retrieval: Algorithm Development and Validation Study (Preprint)
Authors: Chen Yen-Pin , Lo Yuan-Hsun , Lai Feipei , Huang Chien-Hua
Published: January 2021

BACKGROUND

The electronic health record (EHR) contains a wealth of medical information. An organized EHR can greatly help doctors treat patients. In some cases, only limited patient information is collected to help doctors make treatment decisions. Because EHRs can serve as a reference for this limited information, doctors’ treatment capabilities can be enhanced. Natural language processing and deep learning methods can help organize and translate EHR information into medical knowledge and experience.

OBJECTIVE

In this study, we aimed to create a model to extract concept embeddings from EHRs for disease pattern retrieval and further classification tasks.

METHODS

We collected 1,040,989 emergency department visits from the National Taiwan University Hospital Integrated Medical Database and 305,897 samples from the National Hospital and Ambulatory Medical Care Survey Emergency Department data. After data cleansing and preprocessing, the data sets were divided into training, validation, and test sets. We proposed a Transformer-based model to embed EHRs and used Bidirectional Encoder Representations from Transformers (BERT) to extract features from free text and concatenate features with structural data as input to our proposed model. Then, Deep InfoMax (DIM) and Simple Contrastive Learning of Visual Representations (SimCLR) were used for the unsupervised embedding of the disease concept. The pretrained disease concept-embedding model, named EDisease, was further finetuned to adapt to the critical care outcome prediction task. We evaluated the performance of embedding using t-distributed stochastic neighbor embedding (t-SNE) to perform dimension reduction for visualization. The performance of the finetuned predictive model was evaluated against published models using the area under the receiver operating characteristic (AUROC).

RESULTS

The performance of our model on the outcome prediction had the highest AUROC of 0.876. In the ablation study, the use of a smaller data set or fewer unsupervised methods for pretraining deteriorated the prediction performance. The AUROCs were 0.857, 0.870, and 0.868 for the model without pretraining, the model pretrained by only SimCLR, and the model pretrained by only DIM, respectively. On the smaller finetuning set, the AUROC was 0.815 for the proposed model.

CONCLUSIONS

Through contrastive learning methods, disease concepts can be embedded meaningfully. Moreover, these methods can be used for disease retrieval tasks to enhance clinical practice capabilities. The disease concept model is also suitable as a pretrained model for subsequent prediction tasks.
The Impact of the Online COVID-19 Infodemic on French Red Cross Actors’ Field Engagement and Protective Behaviors: Mixed Methods Study (Preprint)
Authors: Heyerdahl Leonardo W , Lana Benedetta , Giles-Vernick Tamara
Published: January 2021

BACKGROUND

The COVID-19 pandemic has been widely described as an infodemic, an excess of rapidly circulating information in social and traditional media in which some information may be erroneous, contradictory, or inaccurate. One key theme cutting across many infodemic analyses is that it stymies users’ capacities to identify appropriate information and guidelines, encourages them to take inappropriate or even harmful actions, and should be managed through multiple transdisciplinary approaches. Yet, investigations demonstrating how the COVID-19 information ecosystem influences complex public decision making and behavior offline are relatively few.

OBJECTIVE

The aim of this study was to investigate whether information reported through the social media channel Twitter, linked articles and websites, and selected traditional media affected the risk perception, engagement in field activities, and protective behaviors of French Red Cross (FRC) volunteers and health workers in the Paris region of France from June to October 2020.

METHODS

We used a hybrid approach that blended online and offline data. We tracked daily Twitter discussions and selected traditional media in France for 7 months, qualitatively evaluating COVID-19 claims and debates about nonpharmaceutical protective measures. We conducted 24 semistructured interviews with FRC workers and volunteers.

RESULTS

Social and traditional media debates about viral risks and nonpharmaceutical interventions fanned anxieties among FRC volunteers and workers. Decisions to continue conducting FRC field activities and daily protective practices were also influenced by other factors unrelated to the infodemic: familial and social obligations, gender expectations, financial pressures, FRC rules and communications, state regulations, and relationships with coworkers. Some respondents developed strategies for “tuning out” social and traditional media.

CONCLUSIONS

This study suggests that during the COVID-19 pandemic, the information ecosystem may be just one among multiple influences on one group’s offline perceptions and behavior. Measures to address users who have disengaged from online sources of health information and who rely on social relationships to obtain information are needed. Tuning out can potentially lead to less informed decision making, leading to worse health outcomes.

EKONOMSKA I DRUŠTVENA OSNOVA STARE SRPSKE DRŽAVNOSTI
Authors: Bodrozic Djuro
Published: January 2021

Istorijski razvoj svakog društva u najtešnjoj vezi je s njegovom ekonomskom osnovom, jer politička moć direktno proizilazi iz ekonomske snage. Ekonomska istorija osvetlila je drevna društva, dala jedan novi ugao posmatranja i razumevanja njihovog uzdizanja i opadanja. Iz takve perspektive moguće je i sagledavanje srpskog srednjovekovnog društva – države Nemanjića. Srpska srednjovekovna kultura razvila se u okrilju vizantijske kulture, najviše kulture srednjeg veka. Vizantijski kulturni obrazac vidljiv je u organizaciji države, društvenoj strukturi, političkoj ideologiji, književnosti, pravnim spomenicima onoga vremena. Po zadužbinama koje su nam ostavili Nemanjići, vidi se da su raspolagali značajnim bogatstvom. Ukazujemo na poreklo tog bogatstva, kao i osnov sticanja. Bogatstvo još uvek nije kapital, a da li će to postati zavisi od toga da li će biti upotrebljeno za podsticaj privredne delatnosti i tehnološke inovacije u proizvodnji. Na tom planu nije bilo velikog uspeha, kako zbog odnosa prema radu, još više zbog prepuštanja trgovačke delatnosti strancima. Usled toga što je novac oticao prema domicilu tih trgovaca, ponajviše u Dubrovnik i Veneciju, nije došlo do razvoja gradskih središta u samoj Srbiji. A bez gradova nema pojačane privredne aktivnosti ni u poljoprivredi, zanatske ili industrijske proizvodnje pogotovu. Jasno je da pojam industrija, kada se govori o srednjem veku, treba shvatiti uslovno.

ULOGA HRVATSKIH MITOLOGEMA U GENERISANjU SRBOFOBIJE
Authors: Krsic Dario
Published: January 2021

U radu se razmatraju neke od najvažnijih hrvatskih mitologema koje su poslužile kao gradivni elementi srbofobije: Crvena Hrvatska, krunisanje kralja Tomislava i Hrvatska do Drine. Hrvatski naučni autoriteti konstruisali su ih uglavnom u 19. veku i utkali ih u kolektivno sećanje sopstvene nacije. Vrlo brzo evoluirale su u faktoide, i kao naučne dogme implementirane su u hrvatski obrazovni sistem. Politička i religijska elita, opterećena velikohrvatskim težnjama i prozelitizmom, uplašena srpskom ekspanzijom sredinom XIX i početkom XX veka, emitovala je strahove od sužavanja hrvatskog mitskog etničkog prostora i katoličke crkvene jurisdikcije. U drugom delu rada, koji će biti objavljen u sledećem broju Političke revije, razmatraće se mit o Hrvatskoj kao predziđu hrišćanstva, Srbima kao Vlasima, te mitovi o gotskom i iranskom poreklu Hrvata.
Expansión de la producción de aceite de palma en territorios campesinos, el caso de Palenque, Chiapas (1996-2018)
Authors: Méndez Rodríguez José Luis , Mier y Terán Giménez Cacho Mateo
Published: January 2021

Este artículo describe y analiza cómo la producción agroindustrial de aceite de palma se ha expandido en territorios campesinos del municipio de Palenque, Chiapas, México. El uso de un enfoque desde la ecología política empírica y cualitativa permitió centrarnos en los campesinos-palmeros y en sus relaciones con otros actores. Durante el trabajo de campo se realizaron entrevistas en plantaciones, localidades rurales y en la ciudad de Palenque. Los hallazgos indican que, en la zona recorrida, se está gestando una territorialidad expresada en la dependencia de los campesinos-palmeros a los ingresos monetarios de la venta del fruto de la palma, quienes en su mayoría no obtienen ganancias económicas considerables, pero sí las mínimas necesarias para mantenerse en la cadena de producción.
Estimation of Municipal Income Distribution in Mexico
Authors: Ojeda Ramírez Mario Miguel , Gallardo Del Ángel Roberto , Cruz López Cecilia
Published: January 2021

Purpose: To ffer an estimation of income distribution measures for municipalities in Mexico for year 2015, and also an analysis of municipal grants on income inequality.Methodological design: We constructed Gini and Atkinson indexes using microdata from the Mexican inter-census survey 2015. We use these inequality indexes along with other several features of poverty and marginality to perform cluster analysis and classify municipalities. From our cluster analysis, we classified the municipalities in four groups: low, medium-low, medium-high and high-income inequality. Afterwards, we performed weighted least squares regressions to observe the effect of fiscal variables on inequality in each group.Results: Although the objective of federal grants has been poverty instead of inequality, we offer evidence that income inequality is inversely affected by the design of federal grants. The regression analysis shows that conditional grants designed to reduce poverty might be increasing inequality, while unconditional grants may help to reduce income inequality even though this is not their policy objective.Research limitations: The main limitation might be the lack of local statistics for other years to perform a dynamic analysis.Findings: The overall effect of conditional grants on income distribution is small but still positive, showing that conditional grants do not reduce income inequality. The estimates show that the total effect is for lower income inequality, especially in those municipalities with high and very high inequality.
De la anfibología a la dramatización. Política y ontología en Gilles Deleuze y Germán Osvaldo Prósperi

Published: January 2021

Este trabajo aborda la discusión política en la obra de Gilles Deleuze, atendiendo al estudio de Germán Osvaldo Prósperi, “Sobre la anfibología de los conceptos de la filosofía política” (2016a). Se destacan sus críticas en torno al problema que implica derivar el pensamiento político del pensamiento ontológico, y se recupera su concepción acerca de la anfibología kan-tiana concerniente al uso de los conceptos filosóficos. Al mismo tiempo, plantea la necesidad de separación que encuentra respecto a la propuesta anfibológica de Prósperi. Finalmente reflexiona sobre la relación entre ontología y política en términos de lo que Deleuze entiende por drama o dramatización
Abasto y consumo de pescados y mariscos en Guadalajara durante el siglo XVII
Authors: De León Meza René
Published: January 2021

Este artículo demuestra que en la ciudad de Guadalajara durante el siglo XVII hubo un alto consumo de pescados y mariscos determinado en gran medida por la imposición de la iglesia católica a no consumir carne roja durante los días de vigilia, cuaresma, viernes y sábado. Comprueba que estuvo muy bien abastecida gracias por un lado a su cercanía con la laguna de Chapala y el río Grande o Santiago y por otro al ser punto de tránsito obligado de los mariscos que venían de tierra caliente rumbo a otras partes de la Nueva España. Esboza como gracias a la importancia económica que alcanzó ese circuito comercial se implementó un sistema de cobro de alcabalas para los productos considerados de lujo, mientras que otros estimados como un bien común quedaron exentos de pagarla. Termina haciendo una serie de propuestas para estudios futuros entorno al comercio colonial de estos productos.
Marxismo, campesinado y economía moral en la historiografía mexicana
Authors: Mora Muro Jesús Iván
Published: January 2021

En el presente texto se exploran las implicaciones de la paulatina transformación de la historiografía mexicana en torno a los estudios sobre el campesinado y sus formas de resistencia ante el embate capitalista. Se argumenta que de una historia marxista (economicista) se pasó a una de tintes más culturalistas (historia social y después a la historia subalterna). Sin embargo, estas nuevastendencias historiográficas se aplicaron de manera muy tardía en el ámbito mexicano. En general, todavía hacia finales de los años ochenta fue patente la fuerte resistencia al cambio de paradigma impuesto por el marxismo ortodoxo, que dificultó la incorporación de la teoría social para el estudio de las clases subordinadas cuyos representantes más importantes fueron E. P. Thompson,Eric Hobsbawm, Lawrence Stone, entre otros. La investigación complementa los balances historiográficos que durante los últimos años se han elaborado sobre el tema. Principalmente, destacan los trabajos de Eric van Young, Leticia Reina, Mary Kay Vaughan y Peter Guardino, quienes han privilegiado en su análisis las obras elaboradas por historiadores y se han olvidado de los teóricos sociales que se dedicaron al tema campesino desde perspectivas antropológicas como Roger Bartra, Arturo Warman, entre otros

Este artículo analiza el impacto de la prima de riesgo en los rendimientos cambiarios y la relación entre la prima de riesgo y los regímenes de tipos de cambio flexibles. Utilizamos el estimador GMM propuesto por Arellano y Bond (1991) en una muestra de 21 países entre enero de 1997 y diciembre de 2015. Nuestros resultados muestran que la prima de cambio variable en el tiempo se concentra en los mercados emergentes y genera una depreciación que oscila entre el 1,8% y el 2,7% mensual. En los mercados desarrollados, hay una prima de riesgo de cambio constante que promueve una apreciación de sus monedas frente al dólar estadounidense. Estos resultados revelan que la UIP y la CIP no se cumplen, aunque su sesgo es menor en los países emergentes. La flexibilidad del intercambio tiene efectos diferentes entre países desarrollados y emergentes. Estos resultados tienen importantes consecuencias para los encargados de formular políticas y los inversores.
Numerus surdus y armonía musical. Sobre el temperamento igual y el fin del reinado pitagórico de los números
Authors: Espinoza Lianggi , Redmond Juan , Palacios Torres Pablo César , Cortez Aguilera Ismael
Published: January 2021

AbstractThe development of philosophical ideas throughout history has sometimes been assisted by the use of handcrafted instruments. Some paradigmatic cases, such as the invention of the telescope or the microscope, show that many philosophical approaches have been the result of the intervention of such instruments. The aim of this article is to show the determining role that stringed musical instruments with frets had in the crisis and generation of philosophical paradigms. In fact, just as the observations of the moon with the telescope broke more than a thousand years of Aristotelian hegemony, the fretted string instruments, predecessors of the guitar, played a central role in the collapse of one of the most influential approaches in the history of Philosophy: Pythagorism. We focus on the fundamental hallmarks of Pythagorism and on how, during the 16th century and from the fretted string instruments, the mathematical-musical notion of equal temperament emerged, which from the middle of the 19th century will be established as the prevailing philosophical-musical paradigm of the West.
Genética humana y el valor de los valores no-epistémicos en la restitución de identidad en Argentina
Authors: Mattarollo Livio
Published: January 2021

Within the context of the discussion about value-free science ideal, Heather Douglas claims that in several cases non-epistemic values are needed for good reasoning in science. In this article I aim at recovering her viewpoint in order to examine the research driving to the Genetic Grandparent Inclusion-Probability Index, a crucial element to restitute the identity of children who were abducted during Argentinean dictatorship (1976-1983). Thus, my purposes are (i) to reconstruct Douglas´ main theoretical contributions, specifically her reasons to reject the ideal as well as the distinction between direct and indirect roles for values in science; and (ii) to analyze the scientific paper resulting from the “Grandparent-Inclusion Index” research. The main hypothesis is (iii) that several decisions of this research, particularly the establishment of what is to be considered sufficient evidence, should be explained by reference to social, ethical and political values. Both because of the non-epistemic consequences of the inquiry related to its inductive risk and because such inquiry is a case in which there is legitimate and necessary integration between epistemic and non-epistemic values and that it is also a case in which Douglas’ criteria of objectivity is reached. By virtue of these reasons, the significance of Douglas’ contribution to the analysis of the relationship between science and politics is emphasized.
Dramatización y argumentación en sociedades orales africanas
Authors: Akue Adotevi Mawusse Kpakpo
Published: January 2021

African traditional societies are oral societies. Orality, in these societies, is the effect as much as the cause of the particular mode of social being of the African man (Aguessy 1979). An African man is socially configured by orality. It is therefore a cultural formatting whose main issue is preservation and transmission, from age to age, of traditions, social norms and practices that determine the relationship of man of orality with the world. Moreover, according to Diagne (2005), the process by which this cultural formatting, specific to traditional African societies is carried out, is the “dramatization”. Dramatization is the ruse of oral reason (Diagne 2005). The aim of this paper is to grasp, through the process of dramatization, cultural particularities of argumentation in traditional African societies. In order to do so, the analysis focuses on the discursive practices through which dramatization is revealed. More precisely, the study of proverbs in eʋe society allows pointing out the specificities of dramatized argumentation in an oral society. The epistemological issue animating this paper is to present a different way of grasping argumentative functions of image and metaphor.
Associativismo literário, trabalho intelectual e o mercado das letras no segundo reinado (1860-1882)
Authors: Nery Gabriela
Published: January 2021

Esse artigo investiga o associativismo literário que emergiu no Rio de Janeiro durante a vigência da lei no. 1083 de 1860, conhecida como “Lei dos Entraves”. Para tanto, foram analisados os estatutos aprovados ou reformados durante a vigência dessa legislação e submetidos ao Conselho de Estado do Império. Dezesseis estatutos compuseram as fontes principais dessa pesquisa, num esforço de compreender como se constituiu uma rede de associações voltadas ao mundo das letras em meados do século XIX. A partir disso, a análise se concentra no desenvolvimento de uma trama social, econômica e cultural que permitiu a expansão do trabalho intelectual, do crescimento do mercado das letras e da informação, além das iniciativas relacionadas à instrução. Esse processo foi fundamental à transformação das empresas jornalísticas a partir da década de 1880 e da expansão do mercado editorial no Rio de Janeiro do Segundo Reinado.
Democracia e reformas: uma análise comparativa entre o discurso de João Goulart na Central do Brasil e o pensamento de Alexis de Tocqueville e John Stuart Mill
Authors: Pimentel Pablo
Published: January 2021

As reformas de base encampadas pelo presidente João Goulart (1919-1976) foram alvo de uma intensa disputa de sentidos e significados em um período de acirrada polarização política. Em plena Guerra Fria, essa luta pela imposição de narrativas teve como elemento fulcral o conceito de democracia. Opositores do então presidente denunciavam tais reformas como um atentado à ordem democrática – ou uma tentativa de impor o Socialismo –, enquanto Jango advogava que seu teor sinalizava para o aprofundamento da democracia no Brasil. Como exercício, este artigo propõe uma análise comparativa entre o aclamado discurso de João Goulart na Central do Brasil e o pensamento dos autores clássicos da democracia liberal, Alexis de Tocqueville e John Stuart Mill, para identificar aproximações e distanciamentos entre o pensamento político desses autores e o discurso do presidente que seria derrubado pelo golpe de 1964. Em específico, daremos ênfase à discussão entre esses autores sobre os temas das reformas agrária e eleitoral presentes no discurso de Jango.

Authors: Yaseen Hadeel , Al-Amarneh Asma’a
Published: January 2021

Using the value added intellectual capital (VAIC) this study aims to investigate the impact of intellectual capital (IC) on the performance of Jordanian banks listed in the Amman Stock Exchange (ASE) during the years 2005-2018. Two empirical models were designed to test the effect of VAIC, and its three components including capital employed efficiency (CEE), human capital efficiency (HCE) and structural capital efficiency (SCE) on banking performance. The results of the study show that there is a significant and positive relationship between VAIC and banks profitability presented by return on assets (ROA). Meanwhile, when VAIC is split into components, SCE, CEE and HCE have a significant and positive impact on banks performance. Yet, CEE has more influence on performance compared to HCE and SCE. This study contributes to the literature as well as practitioners in financial institutions by providing evidence on the influence of intellectual capital on banks performance in an emerging economy, Jordan, in which its national vision and strategy emphasize the importance of intellectual capital in sustaining its economic growth.

Background: The sustainability of the results of mitraclip procedures is
a source of concern. Aims: To investigate risk factors of severe mitral
regurgitation (MR) recurrence after Mitraclip in primary MR. Methods and
results: Eighty-three patients undergoing successful Mitraclip
procedures were retrospectively included. Valve anatomy and Mitraclips
placement were comprehensively analyzed by post-processing 3D
echocardiographic acquisition. The primary composite endpoint was the
recurrence of severe MR. Mean age was 83±7 years-old, 37 (44%) were
female. Median follow-up was 381 days (IQR 195-717) and 17 (20%)
patients reached the primary endpoint. Main causes of recurrence of
severe MR were relapse of a prolapse (64%) and single leaflet
detachment (23%). Posterior coaptation line length (HR 1.06 95%CI
1.01-1.12 p=0.02), poor imaging quality (HR 3.84, 95%CI1.12-13.19;
p=0.03), and inter-clip distance (HR 1.60, 95%CI 1.27-2.02;
p<0.01) were associated with the occurrence of the primary
endpoint. Conclusions: Recurrence of severe MR after a MitraClip
procedure for primary MR is common and results from a complex interplay
between anatomical (tissue excess) and procedural criteria (quality of
ultrasound guidance and MitraClips spacing).
Habilidad combinatoria general y específica relacionada con los componentes del rendimiento en cinco líneas endogámicas de maíz (Zea mays L.)
Authors: Quiroga-Cardona Julio
Published: January 2021

Con el fin de obtener información teórica de los efectos genéticos que gobiernan los componentes del rendimiento y poder tener mayor información que permitiera elegir los mejores progenitores para la formación de híbridos con interés comercial, se estimaron los efectos y la capacidad combinatoria general (H.C.G) y específica (H.C.E) en cinco líneas endocríadas de maíz tropical de endospermo amarillo pertenecientes al programa de mejoramiento genético de maíz tropical de la empresa Sem Latam S.A. Se encontró que los efectos de habilidad combinatoria específica para los caracteres relacionados con el componente rendimiento presentaron valores positivos, no obstante, estos no fueron significativamente distintos de cero, lo que se traduce en la no existencia de un patrón heterótico en las líneas evaluadas. De igual modo, las líneas evaluadas presentaron una escasa capitalización de los efectos genéticos no aditivos o dominantes en el proceso de selección genealógica, permitiendo interpretar la baja manifestación de la heterosis como expresión del vigor hibrido de los cruzamientos F1 comparados con los genotipos parentales.

Authors: Liang Yan-Hong , Wang Kang-Jia
Published: January 2021

This paper proposes a fractal viscoelastic element via He?s fractal derivative, its properties are analyzed in details by the two-scale transform for the first time. The element is used to establish a fractal Maxwell-rheological model, which unifies the fractal creep equation and relaxation equation, and includes the classic elastic model and the classical Maxwell-rheological model as two special cases. This paper sheds a bright light on viscoelasticity, and the model can find wide applications in rock mechanics, plastic mechanics, and non-continuum mechanics.

Authors: Zhang Xin , Fan Yuesheng , Wei Shuxuan , Wang Huan , Zhang Jiaxin
Published: January 2021

With the increase of particulate pollution in the atmosphere, it becomes extremely significant to understand the overall distribution characteristics of particulates and their adsorption of toxic gases for the source analysis and precise controlling of atmospheric particulate matters. The fractal theory was adopted to analyze particle sizes distribution characteristics in Xi?an city, China. Results showed the fractal dimension of particulate matters distribution ranged from 4.32-4.83, with an average fractal dimension of 4.54. A higher fractal dimension predicts a higher concentration of fine particles. Additionally the effects of outdoor temperature, humidity, and wind speed on the fractal dimension were also studied experimentally

Fractal calculus for modeling electrochemical capacitors under dynamical cycling
Authors: Liu Xian-Yong , Liu Yan-Ping , Wu Zeng-Wen
Published: January 2021

The differential model for electrochemical capacitors under dynamical cycling results in discontinuity of the electric current. This paradox makes theoretical analysis of the electrochemical capacitors much difficult, and there is not universal approach to treatment of the problem. This paper finds that the fractal calculus can be powerfully applied to the problem, and a continuous electric current can be obtained as it should be.

Published: January 2021

Refrigerants with low global warming potential (GWP) are much needed in automotive air conditioning systems. This paper compares two refrigerants, R134a (GWP=1300) and R513A (GWP = 573) experimentally. The results show that the latter has lower cooling capacity, lower COP and lower discharge temperature than the former, revealing that R513A is a promising replacement of its high GWP partner.

A modified exp-function method for fractional partial differential equations
Authors: Tian Yi , Liu Jun
Published: January 2021

This paper proposes a novel exponential rational function method, a modification of the well-known exp-function method, to find exact solutions of the time fractional Cahn-Allen equation and the time fractional Phi-4 equation. The solution procedure is reduced to solve a system of algebraic equations, which is then solved by Wu?s method. The results show that the present method is effective, and can be applied to other fractional differential equations.

Authors: Fu Jing-Li , Zhang Lijun , Khalique Chaudry , Guo Ma-Li
Published: January 2021

In this paper, we present the fractional motion equations and fractional non-Noether symmetries of Lagrangian systems with the conformable fractional derivatives. The exchanging relationship between isochronous variation and fractional derivative, and the fractional Hamilton?s principle of the holonomic conservative and non-conservative systems under the conformable fractional derivative are proposed. Then the fractional motion equations of these systems based on the Hamil?ton?s principle are established. The fractional Euler operator, the definition of fractional non-Noether symmetries, non-Noether theorem, and Hojman?s conserved quantities for the Lagrangian systems are obtained with conformable fractional derivative. An example is given to illustrate the results.
