O SISTEMA DE PRECEDENTES E O “ROMANCE EM CADEIA” DE RONALD DWORKIN
Authors: Frois Breno Lopes
Published: February 2022

O presente trabalho tem como intuito analisar o sistema de precedentes positivado pelo Código de Processo Civil de 2015, correlacionando-o de uma forma crítica com a metáfora de “romance em cadeia”, criada por Ronald Dworkin em sua obra “O Império do Direito”. Através da metodologia jurídico-teórica, intenta-se examinar os precedentes como um sistema que exige coerência, utilizando-se como marco teórico as noções de Dworkin acerca do Direito como integridade, numa investigação jurídico-interpretativa, por meio de procedimento analítico de decomposição parcial, limitada ao campo de possibilidade de formação e estabilização do sistema de precedentes no ordenamento jurídico brasileiro.

Surface pressure effect on rivet-connected l-corner plates exposed to axial and flexural loadings
Authors: YAVUZ Mustafa Murat
Published: February 2022

In this study, the stress and deformation behavior of two I-corner plates with rivet connection in bending and tension were investigated. Pure bending and axial tension were applied at the end edge as the boundary condition and fixed support was defined at the other end edge of the plates. The finite element method was used. A suitable validation study was conducted, and its results were compared with the literature cases. A surface pressure was applied to the rounded I-corner. The results are shown in the form of the stress concentration factor. The time-dependent response of applied pressure was also performed to observe the dynamic behavior. The stresses in the plates occurred at the calculated values and as a result the stress concentration factor was about 1.0. The stress concentration factor of the plate in the rivet region is I=0.2 and in the rivets goes up to 5.0. The results are discussed in detail.

Authors: İPEKOĞLU Mehmet , GÜNDÜZ Hasan , ALBAYRAK Önder
Published: February 2022

In this study, linen and cotton fibers obtained from fabric waste were used as filler materials and polyethylene was used as matrix material to produce fiber reinforced polymer composites using injection molding. Use of fabric waste as filler material enables utilization of linen and cotton wastes while decreasing the amount of polyethylene used in the composites resulting in an environmentally friendly material. Prepared samples with varying content of linen and cotton wastes (5, 10 and 20 vol. %) were compared with each other and with polyethylene samples without any filler, based on their yield, tensile and fracture strengths, percent elongation and hardness values. Samples were also evaluated for their chip formation characteristics based on chip lengths at various machining speeds and examined for their visual appearance. Results indicated that linen waste fibers can be used to improve the strength of polyethylene based composites while cotton waste fibers can be utilized to enhance the elongation characteristics of the samples.

Professionalism and Amateurism in Modern Olympic Sports
Authors: Shvetsova A. V. , Fomin Yu. A.
Published: February 2022

The Olympic Games were not the only major sporting event in ancient Greek civilisation. The Nemean, Pythian and Isthmian Games were held simultaneously. After the revival of the Olympic Games in 1896, modern Olympic sport has passed a difficult, albeit not so long-term path. But even earlier, around the middle of the XIX century, professional sports began to form in the developed countries of Europe and the United States. The appearance of professional athletes, both in the ancient world and in modern history, was essentially the result of those significant changes that occurred in the economic, social and political aspects of human life at the stages of its development and the evolution of sports competitions. It can be argued that professional sports (both in ancient and modern times) arose as a particular human activity, the content of which was sports. However, the problem of amateurs and professionalism in modern Olympic sports and the Olympic movement was one of the most significant in the context of introducing Olympic ideals into the life of society, solving the problem of “fair play” and allowing athletes to participate in major international competitions (Olympic Games, World Championships, etc.).
The Social Mechanism of the Functioning of the Institute of Postgraduate Studies in Contemporary Russia
Authors: Vladimirov I. A.
Published: February 2022

The work aims to study the institute of postgraduate studies as a complex social phenomenon. Object: the institute of postgraduate studies as a social phenomenon; subject: the social mechanism of functioning of the institute of postgraduate studies as a composite phenomenon. The paper examines all five elements of the social mechanism of the institute of postgraduate studies; thereby, we are attempting a comprehensive analysis of the behaviour of actors based on the socio-cultural basis and the regulatory framework. The management block provides an analysis of the main functions of the Higher Attestation Commission and determines its role in the functioning of the Institute of Postgraduate Studies. The status block provides a 3-level model of the involvement of various groups of students, scientific and pedagogical personnel and university employees in the institute of postgraduate studies. At the level of perception of postgraduate studies, the author determined its role in the formation of personnel for the labour market. At the level of perception of professional activity, the emphasis is on prestige and economic well-being. And at the level of perception of an academic degree in society, it is necessary to consider the social risks for the holder of an academic degree due to the stereotypes formed in society. The behavioural block provides a comprehensive analysis of the activities of all groups of actors at the three main stages of the postgraduate institute for applicants: educational, individual (plan) and dissertation. In the fifth block (consequences), the author considered the results of postgraduate institute reform in 2013. Finally, the author made disappointing conclusions about the reduction in the number of protections, the loss of prestige of postgraduate studies and the strengthening of barriers to the protection of graduate students.

Authors: Ahn Hyun Seon , Mangulabnan Pauline Anne Therese M , Lee Jeesoo
Published: February 2022

COVID-19 has caused drastic changes to almost all aspects of daily life, with education being the center of these changes and concerns. In particular, teaching approaches have been rapidly reoriented to online versions. Although there is a growing body of literature exploring the views of education during this crisis, a critical need exists to document challenges confronting educators in online teaching. In this paper, we explore the online teaching barriers and motivations of 55 in-service teachers in the Philippines, and how these variables contributed to their perceptions of stress regarding online teaching immediately after the pandemic started. Results demonstrated that respondents’ perceptions of interest in online teaching significantly reduced their perceptions of stress regarding online teaching. However, barriers to online teaching, online communication self-efficacy, and the utility value of online teaching perceived by respondents positively predicted their perceptions of stress regarding online teaching. Furthermore, this paper discusses the future perspectives of online teaching transformation based on expectancy value and self-efficacy theories. Especially, the findings of this paper provide a first look at the stress mechanisms of in-service teachers and initial information regarding stress reduction and professional development of in-service teachers in online teaching.

Published: February 2022

There was an 11% increase in Qur’an illiteracy from 2015 to 2018 although Indonesia is a Muslim majority country. This fact sparks a question on the Islamic Education Studies (Pendidikan Agama Islam, PAI) implementation as a mandatory curriculum in Indonesia, which is still incapable of solving problems related to Qur’an illiteracy. This research was conducted in collaboration with several parties to designate practical steps aim at improving Al-Qur'an literacy in high school students in Bandung, West Java through an action research design 1,975 students. The research results suggest seven practical steps in solving Qur’an reading skills issues as critical reflections in improving students’ Al-Qur’an reading skills. These steps are abbreviated into LITERAT, which summarizes the syntax in reading the Qur’an. Its implementation is proven to have significantly improved students’ Qur’an reading skills. This research concludes that LITERAT is a relatively effective learning method in improving students’ Qur’an literacy. This finding is believed to contribute to the succession of Qur’an illiteracy eradication in West Java.
Using Conventional Rubric and Coh-Metrix to Assess EFL Students’ Essays
Authors: Mahadini Monica Kristin , Setyaningsih Endang , Sarosa Teguh
Published: February 2022

The conventional scoring rubric has been used as a tool to assess students’ writing for years and recently there is growing attention on the use of automated assessment tools. While studies highlighting the use of the tools per se are numerous, not much is available on the use of the combined tools. This study addresses the gap by examining 20 university EFL students’ essays using both assessment tools. The essays were examined based on a conventional rubric which contains five aspects and two categories covering eleven indices of an automated tool called Coh-Metrix. The results of the examination were interpreted and information generated from the tools are compared. The study reveals that the use of both conventional and automated tools laid a more comprehensive picture of the students’ essays.  The results of the assessment are useful to inform students and teachers on areas that need attention in the writing instruction.  Gain and loss on the use of the tools are explained.
A Phenomenological Diagnosis of the ProDuct-based Instruction in EFL’s Writing Class: Barriers and Strategies to Tackle
Authors: Rungwaraphong Piyawan
Published: February 2022

This paper presents a phenomenological diagnosis of the implementation of ProDuct-based Instruction (PDI) in EFL’s writing class in Thailand contexts. PDI is a new instructional method for teaching business English writing. Its key is in the products that are tangible and appeal to human senses; the product’s tangibility serves as a scaffold to help students generate ideas and stimulate analysis and interrogations. The study focused on the first phase of PDI, in which students were required to learn inductively, and was conducted to explore barriers that both the learners and the instructors encounter while learning inductively in the researcher’s PDI approach, and to discover possible solutions to tackle with those barriers. Participants were 3 Thai lecturers of English writing and 60 Thai students from three government universities in Thailand. Data was collected through vignettes, participant observations, and   students’ written texts. Results indicate three major barriers of implementing inductive phase of PDI in Thailand contexts, which include: students’ English reading and grammar skills; students’ inference skill; and teachers’ inductive teaching expertise. The study suggests solutions to tackle these barriers, which include creating a guided graphic organizer, providing formative assessment and feedback for the students, and organizing a PDI training for the teachers who want to adopt PDI in their profession.
Regulatory Support for Biosequestration Projects in Australia: A Useful Model for Transition to Net-Zero Emissions?
Authors: Geroe Steven
Published: February 2022

This paper considers the effectiveness of Australian regulatory measures to support storing atmospheric carbon in plants and organic matter in soils (biosequestration),  a central element of the Australian greenhouse gas (GHG) emission policy through the Emissions Reduction Fund (ERF). Eligible methodologies under the ERF are broader than those in other jurisdictions. Hence Australian experience may have international application. The functionality of Australian regulation to achieve GHG emissions reduction is considered, focusing on provisions relating to additionality, permanence, monitoring, reporting and verification of emissions bio-sequestration. This analysis is conducted by reviewing key publications by research organisations, academics, government departments, industry organisations, environmental organisations and private sector consultancies. While the integrity of Australian biosequestration offsets is generally well regarded, persistent issues have been identified with regard to the additionality of avoided deforestation methane capture in intensive agriculture and landfill gas projects. The proportion of Australian emissions represented by existing biosequestration offset projects is deficient. These issues must be addressed in order to scale up biosequestration projects as an effective element of Australia's net-zero emissions strategy. It can best be achieved by tightening Safeguard Mechanism baselines to drive demand for carbon credits and funding the Clean Energy Regulator to implement effective, independent MRV. Ongoing regulatory reform will be necessary to address such issues as they arise in the course of the implementation of specific methodologies. Nonetheless, ongoing emissions risks relating to biosequestration and other offset projects can only be adequately addressed by complementary policy to reduce emissions at the source.
Freedom of Religion and Gender Equality in Sustainable Development Agenda
Authors: Wardana Khansadhia Afifah , Rahayu Rahayu , Sukirno Sukirno
Published: February 2022

The implementation of Sustainable Development Goals (SDGs) often lacks in human rights perspective, although the goals themselves were created based on the human rights principles. However, further studies in development and international human rights law show that it is essential to highlight that particular relationship. As a member of the international community, states have an extraterritorial obligation to assist one another in developing and fulfilling the human rights of their people. Particularly in the field of freedom of religion or belief and gender equality, which creates a domino effect on other women's rights such as access to justice and education. Although SDG 2030 has expressed its commitment to respect, protect, and promote fundamental freedoms, including one's religion, and to achieve gender equality, the antagonistic construction between those two issues possibly harm the women’s rights movement and does not adhere to the “no one left behind” principle. The lack of recognition between those issues would be damaging and could be deemed a failure to achieve the sustainable development goals. This research was conducted through a qualitative legal analysis by analysing relevant literary sources to understand the hidden link between freedom of religion or belief and gender equality within the sustainable development agenda. Clarity of these complex elements can be beneficial in creating a tool in advocating for women’s rights, especially for those who belong to religious and belief minorities.

Published: February 2022

Marul ülkemizde birçok bölgede üretimi yapılan önemli bir sebze türüdür. Marul üretiminde sorun oluşturan çok sayıda patojen bulunmakta olup bunlardan biri de Marul mozaik virüsü (Lettuce mosaic virus, LMV)’dür. Bu virüsün ülkemizde ki varlığı farklı bölge ve illerden bildirilmiştir. Hastalığın tanısı ve teşhisine yönelik birçok çalışma yapılmış olmasına rağmen ülkemiz LMV izolatlarının tüm genom dizilimlerinin belirlenmesine yönelik bir çalışma yoktur. Bu nedenle bu çalışma kapsamında ülkemiz orijinli bir LMV izolatının (LMV-CNK) tüm genom diziliminim ortaya çıkarılması hedeflenmiştir. Gerçekleştirilen analizler sonucunda tüm genom dizilimi ortaya çıkarılan izolatın, diğer ülkelerdeki LMV izolatları ile nükleotit seviyesinde, aminoasit seviyesinde sırasıyla %82-98 ve %92-99 oranında benzerlikler gösterdiği saptanmıştır. Yapılan filogenetik analizler sonucunda ise LMV-CNK izolatının genel olarak Fransız ve Asya orijinli izolatlar ile yakın ilişkili olduğu görülmüştür. Bildiğimiz kadarıyla çalışma kapsamında ülkemizde ilk kez bir LMV izolatının tüm genom dizilimi belirlenmiş ve biyoinformatik analizleri yürütülmüştür. Bundan sonra yapılacak çalışmalarda ülkemizde daha fazla sayıda ve farklı LMV izolatlarının tüm genom düzeyinde dizilenmesi ve analizinin yapılması düşünülmektedir. Ayrıca elde edilen izolatların popülasyon düzeyinde genetik çeşitliliğinin belirlenmesi de izolatlar arasındaki farklılıkların ortaya çıkarılması açısından önem taşımaktadır.

El manejo de la vía aérea es un reto constante para el médico y muy particularmente para el anestesiólogo, ya que en su quehacer diario, comúnmente se enfrenta a situaciones en las cuales puede tener dificultades para acceder a ésta y lograr la intubación endotraqueal del paciente, más aun cuando se trata de una vía aérea difícil inesperada., para ello la tecnología y la medicina se han ideado nuevas maneras de realizar este procedimiento con una mejor curva de aprendizaje y sobretodo mejor visualización, tal es el caso de los videolaringoscopios. La dificultad de tener uno de ellos (sobre todo de marca internacional reconocida) es el costo, por lo que hemos diseñado un videolaringoscopio “artesanal” en nuestro país, con ciertas diferencias a otros que han salido en otros países, con magnifica resolución y de accesos fácil para los anestesiólogos sobretodo.

Industrialization and indiscriminate discharge of sewage being implicated in environmental pollution is responsible for the release of micropollutants which over time is expected to alter the physiology and metabolic pathways of microbiota native to the environment. This study was undertaken to track antibiotic resistant genes in industrial wastewater. Heterotrophic bacterial count indicated a vast abundance of culturable bacteria (76-232.66× 104 Cfu/ml). Hydrocarbon utilizing bacteria count ranged between (91.66 - 111.6×104 Cfu/ml). Antibiotic resistant bacteria isolates from industrially impacted wastewater identified by Sanger’s sequencing included Bacillus lichenforminis (KF737353.1), Alkanindiges sp. 5-0-9 (LT158291.1), Bacillus thuringiensis (MK875170.1, MK517632.1 EU697392.1) Bacillus altitudinis (KY777585.1), Bacillus cereus (KR185830.1) and Bacillus subtilis (MK124647.1). This study infers that industrial effluent is a potent reservoir for antibiotic resistant bacteria of environmental and public health concerns.
ANALISIS PERFORMANSI ROUTING PROTOKOL DSR, DSDV DAN ZRP PADA MANET MENGGUNAKAN NETWORK SIMULATOR 2
Authors: Ismail Aris Dwi
Published: February 2022

Routing protokol adalah aturan atau cara pencarian jalur terbaik yang digunakan untuk mengirimkan paket data dari node pengirim ke node penerima. Paket akan melewati beberapa node penghubung melalui mekanisme pembentukan tabel routing. Simulasi dengan menggunakan tools Network Simulator-2 diharapkan dapat membantu menganalisis kemampuan atau kinerja dari masing-masing jenis routing protokol pada kondisi lingkungan jaringan tertentu. Yang nantinya akan didapatkan nilai parameter pengukuran dari routing protokol DSR, DSDV dan ZRP yaitu berupa : Packet Delivery Ratio (PDR), Delay, Konsumsi Energi, Packet Loss, dan Routing Overhead. Analisis performansi dengan melakukan simulasi menggunakan Network Simulator 2 didapatkan hasil parameter konsumsi energi paling hemat pada routing protokol DSDV skenario 10 node dengan 0,9701 joule. Untuk parameter delay mendapatkan hasil 0 m/s. Sedangkan pada parameter routing overhead pada skenario 100 node mendapatkan hasil 4,6707 %. Pada hasil parameter Packet Delivery Ratio (PDR), ZRP memiliki nilai tertinggi pada parameter ini yaitu pada skenario 20, 50 dan 100 node dengan hasil 100 %. Berarti dalam hal keberhasilan routing protokol ZRP dalam mengirimkan paket sangat maksimal, sehingga secara otomatis parameter packet loss akan rendah yaitu 0 %.

O índice afetivo de Arthur Less
Authors: Silva Ruan Nunes
Published: February 2022

O presente trabalho-índice oferece uma desleitura do romance As Desventuras de Arthur Less de Arthur Sean Greer ao propor uma investigação sobre branquitude, cisgeneridade e heteronormatividade baseada em teorizações sobre os afetos. Ao focar em afetos como felicidade, conforto e desorientação, o índice destaca as relações entre o protagonista do romance, Arthur Less, e o mundo que o cerca, propiciando uma discussão das formas pelas quais ele é orientado para uma “vida boa” na qual valores brancos, cisgêneros e heteronormativos o impedem de pensar a sociedade na qual vive. Conclui-se que a elaboração de um índice afetivo do romance possibilita um questionamento da estrutura que Arthur Less ignora, em especial, elementos que não só visibilizam, mas questionam a branquitude e a cisgeneridade.
Relações raciais: por um pensar crítico sobre a branquitude
Authors: Arruda Maria Auxiliadora Almeida
Published: February 2022

O racismo e a discriminação racial são constitutivos da formação social brasileira. Nesse contexto, este artigo propõe uma discussão crítica sobre a branquitude, que se refere à forma como os sujeitos brancos se apropriam da categoria raça e do racismo na constituição de suas subjetividades e, ao se apropriarem, acreditam que “ser branco” determina características morais, intelectuais e estéticas dos indivíduos e que os distinguem dos “outros” racializados. Para isso, foram priorizados estudos críticos sobre a branquitude cuja lógica é fazer um deslocamento de estudo dos “outros” racializados para o ponto central da construção da ideia de raça, ou seja, para os brancos. Na direção de uma educação antirracista propõe-se uma pedagogia crítica da branquitude no sentido de problematizá-la enquanto modelo universal de humanidade, por meio de uma prática dialógica em que os sujeitos e grupos sociais (re)construam a branquitude como uma representação não fixa e guiada por referenciais que se associam com lutas, relações e práticas democráticas e comprometidas com a humanização autêntica dos sujeitos.
