The Return of Typhoid Mary? Immigrant Workers in Nursing Homes
Authors: Milczarek‐Desai Shefali , Sklar Tara
Published: November 2021

Nursing homes are dependent on immigrant, female labor as nursing aides, yet these workers are provided with minimal employment benefits, which has led to devastating consequences for vulnerable, older residents during COVID‐19. Emerging research suggests that aides are contributors to the increase in coronavirus outbreaks due to working in multiple long‐term care facilities and refer to these individuals as “superspreaders.” Specifically, aides have been tied to unwittingly passing on the virus as they may be asymptomatic or pressured to work by employers while symptomatic with limited access to paid sick leave. The plight of these women harkens back to “Typhoid Mary”—also a poor, immigrant woman who was accused of spreading typhoid fever a century ago. This article applies lessons learned from Mary's shocking and tragic trajectory, then employs critical race theory and feminist jurisprudence to highlight examples of structural and institutional disparities that exist in current paid sick leave laws. Recommendations call for improved oversight in delivery of quality and safety in long‐term care by addressing racial, gender, and economic inequalities through paid sick leave laws coupled with strong enforcement.

Authors: Kusrini Elisa , Miranda Suci
Published: November 2021

Performance measurement in supply chain management is essential to facilitate the company to achieve effectiveness and efficiency to meet customer satisfaction. One of the models to measure performance in the supply chain is SCOR version 12. This model presents a business process framework, performance indicators, best practices, and unique technologies to support communication and collaboration between supply chain partners to increase the effectiveness of supply chain management and the effectiveness of supply chain improvements. This research used SCOR 12.0 to identify the performance metrics within the supply chain. A make-to-order small-medium enterprise (SMEs) in Yogyakarta, Indonesia, is the object of the research. We portrayed the business scope diagram by identifying the process elements in each tier (plan, source, make, deliver, return, enable) and decomposing each Process into performance attributes, i.e., Reliability, responsiveness, agility, cost, and asset management efficiency. We obtained three performance attributes (Reliability, responsiveness, and cost) based on observation and interviews, 52 performance metrics spread into 47 process elements. The SMEs can use the performance metric framework to measure supply chain management performance in make-to-order products.
Establishing the Method to Predict the Limited Roll Angle of the Vehicle Based on the Basic Dimensions
Authors: Nguyen Duc Ngoc , Nguyen Tuan Anh , Hoang Thang Binh , Dang Ngoc Duyen
Published: November 2021

The roll angle of the vehicle φ is a characteristic parameter for the vehicle's instability. This value appears when the vehicle steers. If the vehicle’s body is tilted, the value of the vertical force at the wheels Fzij will also change. When the value of Fzij reaches zero, the wheel will be lifted off the road, the rollover phenomenon can occur. At this time, the roll angle of the vehicle will reach the maximum value φmax. Previous researches have often used only the vehicle dynamics model to determine the limits of this phenomenon. However, the calculation and simulation process are quite complicated. Therefore, this research has proposed a novel method that can calculate the limit of the rollover phenomenon more easily. In this research, the Rollover State Function (RSF) was established to calculate the limited roll angle of the vehicle. According to the content of the paper, this function depends only on the basic dimensions of the vehicle such as the height of center of the gravity, the track width, etc. Besides, it has relatively high accuracy, even when the vehicle's mass changes, its difference is not large. Therefore, the results of the paper can be applied to later studies to predict the rollover phenomenon.
The Application of Copula Continuous Extension Technique for Bivariate Discrete Data: A Case Study on Dependence Modeling of Seismicity Data
Authors: Rizal Jose , Gunawan Agus Y. , Indratno Sapto W. , Meilano Irwan
Published: November 2021

The Copula approach for continuous variables is highly developed, while discrete ones are underdeveloped due to computational difficulties and sometimes algorithm failure to convergent. Therefore, providing an alternative method for discrete variables becomes an essential issue. In this paper, a simple method is proposed to answer the problem by applying the Continuous Extension Technique (CET). This is carried out by adding random independent perturbations in the form of either Uniform distribution U(0,1) or (U(0,1)−1), and the discrete variables are treated as continuous. Subsequently, a Copula model for resulted variables is estimated based on the Copula theory for continuous variables. This method is called a Copula continuous extension technique. Our analytic and simulation approaches show that both random perturbation forms produce the same Kendall’s Tau measure and the selected Copula bivariate model. As illustrations, the proposed method is applied to the seismicity data obtained from the annual frequencies of earthquakes that occurred in the Sumatra megathrust of Indonesia, from January 1971 to December 2018, with magnitudes ( Mw ) of at least 4.6. Based on the selected Copula models, our simulations confirm the evidence of dependence seismic activity in each of the two adjacent large earthquake sources. These results provide new information regarding the seismicity behavior in the Sumatra megathrust.
The Availability of Hybrid Nano Adsorption-Multi Stage Ejector Cooling Cycle with a Different Type of Steam Generator
Authors: Al-Dabbas Mohammad Awwad Ali
Published: November 2021

Ejectors are a kind of pump that does not have any moving components. In certain cases, the motor fluid may be a liquid, steam, or another gas. The research focuses on using nano adsorption combined with a multi ejector to fuel a sophisticated nano adsorption power plant, which is equipped with three shapes of steam boiler generators. The simulation was accomplished by implementing it with the cooperation of the two programs MATLAB A and MATLAB B, together with a solid flow. To raise the temperature of the working fluid before it enters the generator, a jet pump is positioned before the generator. To enhance the mass flow rate of vapor going into the ejector, a two-stage adjustable booster was added after the evaporator, which gives low evaporator temperature. A further experiment in which the two-stage adjustable booster was used before the generator to reduce the amount of work done by the generator. The ejector's cooling unit is powered by steam created from many energy sources powered by advanced hybrid heat and power systems, including solar energy and steam produced by the electric steam generator. The different devices are either directly triggered by a thermal source to achieve heating, cooling, or refrigeration. The steam boiler generator is the core of the cooling unit; in this research, various types of steam boiler generators are linked with adsorption units, such as steam-powered solar boilers, gas boilers, solid fuel steam boilers, and electric boilers. Heat exchangers were utilized to transfer heat from the solar chimney to the ejector cooling unit. The impact of various ejector geometries on the advanced cooling unit was studied and simulated for the single, double, and triple nozzle ejector. There were no issues with the more effective cooling unit. This unit performed better than traditional adsorption cooling units, having a greater efficiency.
Entre la vida y la muerte: el dolor. Un acercamiento foucaultiano
Authors: Cabrera Dulce
Published: November 2021

Este trabajo se propone, desde una perspectiva foucaultiana, reflexionar acerca de la incorporación del dolor en una ética de la resistencia. En el artículo se revisan algunos planteamientos relacionados con el nacimiento dela clínica y las tres conferencias ofrecidas por Foucault durante 1974 en Río de Janeiro, para analizar el abordaje de la vida, la enfermedad y la muerte, y el gobierno de los cuerpos. El argumento central es que el discurso de lamedicina poco o nada puede hacer con el dolor, porque éste se constituye en un espacio intermezzo entre la vida y la muerte. Aunque el dolor amenaza el despliegue de la positividad de la vida y de la salud plena, no conduce a suaniquilación. En este sentido, es posible pensar en una ética capaz de oponer resistencia a la industria del fármaco o al mercado de la salud, y apostar por una cierta experiencia que ayude a reconocer el dolor como un procesocolectivo.

Published: November 2021

O artigo apresenta diferentes modos (ou possibilidades) de se produzir pesquisas no campo da saúde e da educação, a partir de autores do campo da filosofia francesa contemporânea, em particular Michel Foucault, Gilles Deleuze e Étienne Souriau. Nossa intenção foi, ao relatar as experiências de pesquisa vividas (e em processo), apontar para a multiplicidade como potência de novas práticas de cuidado, seja na saúde ou na educação (focos desse texto), assim como novos modos de existência, pautados por assujeitamentos e desassujeitamentos contínuos. Os trabalhos de investigação aqui apresentados estão sendo desenvolvidos no âmbito de dois programas de pós-graduação de uma universidade pública brasileira e buscam ressoar para (nos fazer) pensar e lançar algumas proposições possíveis através de um traçado de linhas que, de algum modo, podem atravessar as duas investigações naquilo que chamaremos de economia do cuidado. As indagações aqui apresentadas buscam, por fim, instigar que outras produções sejam possíveis nas intersecções – nada triviais – entre diferentes áreas do conhecimento.Palavras-chave: Práticas de cuidado.

Penelitian ini bertujuan untuk menganalisis pemahaman konsep awal pra-perkuliahan mahasiswa program studi pendidikan fisika FKIP Universitas Sriwijaya yang akan mengikuti perkuliahan astrofisika. Metode yang digunakan dalam penelitian ini adalah metode deskriptif yaitu mengidentifikasi pemahaman konsep awal materi benda-benda langit pada mata kuliah astrofisika. Topik benda benda langit merupakan salah satu topik yang dibahas dalam perkuliahan astrofisika yang merupakan perkuliahan pilihan wajib pada program studi pendidikan fisika. Penelitian ini menggunakan tes diagnostik dua tingkat yang terdiri dari opsi pertanyaan dan opsi alasan. Sampel penelitian yaitu 22 (dua puluh dua) mahasiswa yang akan mengikuti perkuliahan astrofisika. Penelitian ini menghasilkan bahwa pemahaman konsep awal tentang benda-benda langit yang dimiliki oleh mahasiswa sebelum perkuliahan diberikan cenderung heterogen. Pemahaman yang tepat tentang materi benda-benda langit masih beragam dengan pemahaman yang tidak tepat maupun hanya bersifat tebakan. Tergambar bahwa lebih banyak mahasiswa dengan pemahaman yang tidak komprehensif dibandingkan dengan yang pemahaman konsep yang tepat. Hasil penelitian yang berupa gambaran pemahaman konsep awal mahasiswa ini bisa diimplikasikan oleh pengampuh mata kuliah astrofisika untuk menentukan teknik pembelajaran inovatif yang akan digunakan selama pembelajaran agar mahasiswa bisa memperbaiki pemahaman konsep awal yang belum tepat. This study aims to understand the initial pre-lecture concept of students of the physics education program, FKIP Sriwijaya University, who will take astrophysics lectures. The method used in this study is a descriptive method to identify the understanding of the initial concept of celestial objects in the astrophysics course. Celestial bodies are topics discussed in astrophysics lectures, which are compulsory elective courses in physics education study programs. This study uses a two-level diagnostic test consisting of question options and reasonable options. The research sample is 22 (twenty-two) students who will take astrophysics lectures. This study showed that the initial concept of celestial objects that students had before the lecture was given tended to be heterogeneous. The correct understanding of the material of the celestial bodies is still diverse with an incorrect understanding or only guesswork. It is illustrated that more students have an incomplete understanding than those with a proper understanding of the concept. The study results in the form of an overview of students' initial concept understanding can be implied by astrophysics course supervisors to determine innovative learning techniques that will be used during learning so that students can improve their understanding of initial concepts that are not yet appropriate.

Data were obtained by using problem-solving tests, questionnaires, and interviews with students and teachers of physics subjects. Data analysis was carried out in a qualitative descriptive manner. The results of the study: (1) Based on the results of the problem-solving tests that students have in the low category with a score range of 0 to 10, 87 students, 12 students in the medium category with a score range of 11 to 20, and 2 students in the high category with a score range of 21. up to 30. (2) Based on the results of the questionnaire on student learning experiences and teacher performance in delivering physics learning in class, it can be seen that: (a) students do not like physics subjects, (b) teachers often teach using the lecture method, rarely use other learning media, (c) students have difficulty working on the problem-solving skills test. (3) results Based on teacher and student interviews, it can be seen that problem-solving in physics is important to know. According to students, the obstacles in improving problem-solving skills were due to a lack of interest in physics subjects, and the characteristics of physics subjects were quite complicated. Likewise, the teacher's response cannot be made well because of student interest, so that improving problem-solving skills cannot be done effectively and can only be done in certain classes. Thus, it can be said that the problem-solving skill profile based on the ACCES criteria in class XI students of SMA Negeri 1 Sekaran can be categorized as low and difficult to train.

On the motivation variable strongly disagree at 6%, disagree 16%, agree 56% strongly agree 22%. Meanwhile, on the online learning perception variable, 4% strongly disagree, 9% disagree, 64% agree, and strongly agree 23%. The implications of the importance of the results of this study are as initial data and as suggestions for improving education in the new normal.
DO CARÁTER ESTÉTICO AO CARÁTER SUBJETIVO DA PAISAGEM
Authors: Silva Claudio Antonio Vieira da
Published: November 2021

O presente trabalho traz uma síntese de ideias e recortes referentes ao conceito de Paisagem, no viés da Geografia. Os esforços teóricos lançados não são definitivos, entretanto aglutina referências essenciais do conceito de Paisagem, com vinculações teóricas e traz entendimentos e reflexões sobre esta abordagem teórica de Paisagem. Nesse sentido, o objetivo desse trabalho busca alçar um direcionamento teórico de Paisagem, na perspectiva geográfica, através de uma breve revisão bibliográfica, necessária para argumentação e organização das ideias. Assim, a intencionalidade do presente trabalho é uma constante construção de conhecimento e que outras leituras e esforços devem ser somados as ideias aqui colocadas. Para compor o quadro teórico, foi feita uma trajetória teórico-temporal compreendendo: a dimensão estética, o caráter físico-morfológico e a leitura subjetiva da Paisagem. Essa trajetória teórica supracitada foi sendo construída à medida que a bibliografia foi definida, respeitando a linha do tempo dos autores e ideias. Por meio do quadro teórico construído enfatiza-se que apesar do conceito de paisagem ser polissêmico, envolve entendimentos e aplicações diversas, sendo necessário nos aportes da investigação cientifica. Com isso, trouxe uma abordagem que perpassa, numa escala temporal, considerações teóricas nos estudos de Paisagem.
DESENVOLVIMENTO SÓCIO-ESPACIAL EM MARCELO LOPES DE SOUZA E O DIREITO À CIDADE EM HENRI LEFEBVRE
Authors: Paulino Cassiano Lobato
Published: November 2021

Esse artigo tem como objetivo analisar algumas premissas sobre desenvolvimento sócio-espacial em Marcelo Lopes de Souza e o direito à cidade em Henri Lefebvre. A análise se desenvolve, principalmente, a partir da revisão bibliográfica de obras de Souza (2006a; 2006b; 2012; 2013) e de Lefebvre (1969; 1991; 1999). Assim, identificou-se, não só alternativas e possibilidades no âmbito teórico-metodológico, mas também político e prático para a compreensão da dialética da cidade. Nesse sentido, foram percebidas algumas semelhanças na postura política e ideológica dos presentes autores no que diz respeito ao entendimento dos conflitos e contradições presentes na cidade. Essas semelhanças em analisar a totalidade urbana podem ser resumidas, de forma bastante peculiar, na crítica radical: ao Estado; ao positivismo tecnocrático; ao planejamento e gestão urbana; a sociedade burocrática de consumo dirigido; a sociedade heteronômica; a funcionalização do espaço urbano e ao modelo de desenvolvimento capitalista, etc. Entretanto, ao analisarem a totalidade urbana, os autores enxergam uma potência nos resíduos, isto é, nos movimentos sociais e na autonomia individual e coletiva, como componentes essenciais da luta pela reforma urbana, portanto, essa reforma teria como objetivo principal a melhoria da qualidade de vida e o aumento da justiça social, assim como a materialização do direito à cidade. Por fim, a reflexão aqui desenvolvida subsidiou na análise da efetividade do Plano Diretor Participativo como instrumento de Planejamento e Gestão Urbana no Município de Oriximiná-Pará no período de 2006-2014.

Este artigo tem como objetivo compreender a relação entre paisagem e memória a partir da percepção dos moradores, considerando a importância de reconhecer os valores do seu patrimônio cultural aqui representados por suas formas simbólicas espaciais. Apesar de não ter destaque no que concerne a uma oficialidade, as paisagens culturais do município de Itapiúna trazem em sua materialidade as dimensões simbólicas que refletem os costumes, as tradições, a história e a cultura de seus moradores. Para a análise do real, buscamos uma prospecção que consistiu em realizar registros fotográficos e a realização de entrevistas com os moradores com o intuito de compreender a percepção entra paisagem e o patrimônio.  A partir da análise dos resultados, podemos aferir como os seus moradores experienciam esta paisagem em um contexto da memória e das práticas de sociabilidade.

Published: November 2021

We performed an innovative STEM outreach project. High school students from the Colombian robotics’ designed a prototype of a Lunar Loo named Tech Lunar Toilet (TLT) that was part of the international HeroX-NASA Challenge. These experiences were possible thanks to a wonderful network of collaboration. As a result of this program, the students that participated were able to cultivate their curiosity, strengthen their scientific skills and increase their interest in pursuing careers in STEM fields. Simultaneously, they were able to contrast visual and instrumental data obtained from the robotics and new technologies that can be performed in the microgravity environments for future space explorations. The efficient TLT suction system will guarantee proper operation in both microgravity and lunar gravity. Most of the structure can be built in a 3D printer using PLA as a raw material. This polymer made from renewable resources with mechanical properties comparable to the petroleum-based ones will allow reducing the weight of the structure. We recognized that our project-based education is a powerful engine for development. We share our methodology for the construction of our TLT that can be used in microgravity. We also show the progression and impact of this innovative project of scientific dissemination.
Strategic Alliance for Resilience in Supply Chain: A Bibliometric Analysis

Published: November 2021

Resilience is a particularly important quality for supply chains in this turbulent environment. Resilience in supply chain is the ability to retain, resume, and recover operations after an intense destructive incident. One of the strategic solutions for managing supply chain disruptions is to establish collaboration and strategic alliances in order to achieve competitive advantage. Therefore, given the increasing publication of articles in areas of strategic alliances and supply chain resilience, it is a good opportunity to review these articles, identify gaps in the current literature, demonstrate links between the two areas, and provide suggestions for future research. For these purposes, a bibliometric analysis has been performed on literature available on the Web of Science database. The distribution of articles based on year and country, influential journals, research areas, authors, affiliations, keywords, citations, and reference co-citation analysis are discussed. Results indicate that studies about strategic alliances, meant to increase resilience, are growing in areas such as “Management”, “Operations research”, “Management science”, and “Business”. Furthermore, the sources could be categorized in five clusters; namely “From knowledge concept to value creation”, “Internal and external relationships”, “Logistics and supply chain performance”, “Intellectual capital and strategic management”, and “Critical success factors and alliances”. This article can be useful for both practitioners and academics who explore the topic of strategic alliances and resilience in supply chain and also offers managers the opportunity to overcome supply chain disruptions and negative consequences of risks by becoming familiar with the key concepts of resilience. The persistence of businesses and supply chains is guaranteed through communicating with partners and even competitors in the light of alliance according to the findings of this research. Managers can pay attention to the integration of the supply chain to improve resilience and increase collaboration between suppliers and customers. Given the research results, strategic alliances can be noted in expanding organizational entrepreneurship, and shaping strategic collaboration networks in light of strategic alliances.
Fuzzy Transfer Learning in Time Series Forecasting for Stock Market Prices
Authors: Pal Shanoli Samui , Kar Samarjit
Published: November 2021

Transfer learning involves transferring prior knowledge of solving similar problems in order to achieve quick and efficient solution. The aim of fuzzy transfer learning is to transfer prior knowledge in an imprecise environment. Time series like stock market data are non-linear in nature and movement of stock is uncertain, so it is quite difficult following the stock market and in decision making. In this study, we propose a method to forecast stock market time series in the situation when we can use prior experience to make decisions. Fuzzy transfer learning (FuzzyTL) is based on knowledge transfer in that and adapting rules obtained domain. Three different stock market time series data sets are used for comparative study. It is observed that the effect of knowledge transferring works well together with smoothing of dependent attributes as the stock market data fluctuate with time. Finally, we give an empirical application in Shenzhen stock market with larger data sets to demonstrate the performance of the model. We have explored FuzzyTL in time series prediction to unerstand the essence of FuzzyTL. We were working on the question of the capability of FuzzyTL in improving prediction accuracy. From the comparisons, it can be said fuzzy transfer learning with smoothing improves prediction accuracy efficiently.
