Scientific Practices play a central role in the Next Generation Science Standards, influencing the standards of more than 70% of students in the United States. Therefore, a view of what has been studied about Scientific Practices in Science Education, globally in the last decade is relevant. Thus, 44 articles from international journals in Science Education in the last decade (2010-2019) were analyzed. This review focuses on the specific research contexts of these articles. The research objectives were: I) To identify in which contexts the authors carried out research involving Scientific Practices and II) To critically discuss the research contexts of Scientific Practices and find research gaps. For this, a systematic literature review was conducted, guided by Bardin's Content Analysis (2011) and the guide to a systematic review by Okoli (2015). Regarding the contexts, six categories were identified: Scientific Practices and teaching proposals (C1); Scientific Practices and distinct theoretical frameworks (C2); Scientific Practices and students (C3); Scientific Practices and assessments (C4); Scientific Practices and teachers (C5); and Scientific Practices and the curriculum (C6). There was a predominant trend to relate Scientific Practices and teaching proposals (38.6%) and Scientific Practices and different theoretical frameworks (22.7%), totaling more than 61% of the analyzed articles. Research gaps have been identified, such as the need for further research on the relationship between Scientific Practices and students (learning) and Scientific Practices and teachers (teaching). Research in this regard can help to clarify: How have students engaged in Scientific Practices? How can teaching be organized to promote Scientific Practices? And what are the relationships between Scientific Practices, school subjects and specific content? The findings of the study revealed that a greater diversity of research contexts is necessary to fully understand the connections between Scientific Practices and the many dimensions involved in Science Education. It was found that there is a need for more research that addresses Scientific Practices as its main focus, considering the importance the concept is given in guiding documents.

By ethnic-racial relations one understands the relations established between ethnic groups whose base is guided by race category, seen on a social perspective. Schools should be an environment propitious to the promotion of Education for Ethnic-Racial Relations, the teacher being an indispensable agent in this process. The present study is characterized as documentary research with a qualitative approach that sought to analyze, in a comparative perspective, evidence of a proposal for Education for Ethnic-Racial Relations present and/or absent in the Curriculum Guidelines and in the Common National Base for Initial Teacher Training (Resolution 2/2019), as well as the possible implications for the teaching of anti-racist Science and Biology in Brazil. The study leads us to conclude that the new Curricular Guidelines and the Common National Base for the Initial Teacher Training do not bring concrete evidence of an effective proposal for Education for Ethnic-Racial Relations as proposed by Resolution 2/2015, which was hastily revoked by Resolution 2/2019. The absence of these indications tends to result in negative implications for the teaching of anti-racist Science and Biology, since it was previously supported, we had found in the guidelines for teacher training an alternative to insert the study of ethnic-racial relations in undergraduate courses in the area. We hope that this study will collaborate for research in the area of ​​teacher training and ethnic-racial relations in the teaching of Science and Biology, especially for educational policies aimed at training teachers.
Teachers’ misconception concerning valence and valency in chemistry
Authors:   National Council of Educational Research and Training (Retired), New Delhi, India, Sindhu Raghubir Singh
Published: November 2021

A study on the misconceptions developed or held by teachers related to the two terms valence and valency was undertaken. A total of 48 teachers (26 males and 22 females) teaching the chemistry component of science subject to 14- to 16-year-old students, in 48 schools affiliated to one district, were randomly selected for the study by taking one teacher from each school. One session was devoted for administering the questionnaire among the teachers and second session (with a gap of one day) was for addressing the teacher’s misconceptions. From the analysis of the responses, it was found that the two terms although they have the same meaning were misconceived as having different meanings. Due to this a misleading relationship between the two terms was discovered. Even the highest numerical value of valence was misconceived. The possible reasons for these misconceptions were identified. A simple, brief, and precise description of the concepts was presented to remove the misconceptions of the teachers.

This study aimed to investigate the effect of an online science course on the academic achievement of a fifth grade ‘World of Living’ unit, which was carried out by using the materials created with web 2.0 tools, as well as to determine the students' opinions about the application. This study consisted of a total of 120 fifth grade students studying in state schools in Istanbul during the academic year of 2020-2021. In determining the study group, purposeful sampling methods were used. In the experimental group (n = 60), the course was taught with web 2.0 supported materials; in the control group (n = 60), instruction was made by adhering to the activities in the textbook. The research was carried out by making use of mixed method research. A quantitative quasi-experimental model with pretest and posttest control groups was used. In the qualitative dimension, opinions were obtained from the students after the application. In the study, semi-structured interview form and academic achievement test prepared for the unit of the world of living things were used as data collection tools. While the data obtained from the students to the achievement test before and after the application was transferred to a statistical package program and analyzed; the data obtained from the interview form were analyzed using content analysis. When the posttest academic achievement score data obtained from the students were compared as a result of the study, it was found that there was a significant difference in favor of the experimental group. In addition, results from the interviews, revealed that students found science teaching with web-supported materials fun and enjoyable and that they wanted these to be used in science lessons. As a result of this study, it is recommended that web 2.0 tools be used by educators in science education.
The The perceptions of Senior High School students and teachers about organic chemistry: A Ghanaian perspective
Authors:   Department of Chemistry Education, University of Education, Winneba. Ghana, Nartey Esther , Hanson Ruby ,   Department of Chemistry Education, University of Education, Winneba. Ghana
Published: November 2021

The purpose of the study was to determine the perceptions that senior high school (SHS) chemistry students and teachers have about organic chemistry as well as to compare organic chemistry topics that are difficult for students and teachers. Simple random sampling (lottery) and purposive sampling methods were used to select a sample of one hundred (100) SHS students who studied elective chemistry and ten (10) chemistry teachers. The research instruments used to collect data for this study were the ‘organic chemistry perceptions questionnaire for students’ (OCPQS) and ‘organic chemistry perceptions questionnaire for teachers’ (OCPQT). Descriptive statistics (frequencies and percentages) were used to analyze the data collected. The findings revealed that these SHS students have a fairly positive perception of organic chemistry while their teachers had a highly positive perception of organic chemistry. Preparation and chemical reactions of alkenes, preparation and chemical reactions of alkynes, structure and stability of benzene, reactions of benzene, comparison of reactions of benzene and alkenes, petroleum, polymers and naming of alkanes and structural isomerism were perceived by students as difficult to understand. The rest of the Ghanaian SHS organic chemistry topics (26 out of 34 topics) were perceived as easy to understand by students. Also, the teachers perceived all the SHS organic chemistry topics as easy to teach with the exception of reactions of benzene. The insights gained about teachers’ and students’ perceived difficult organic chemistry topics in this study imply that teachers’ perceptions and how these are communicated to students can have significant effects on learning. The authors believe that both teachers and learners could benefit from this increased awareness of perceptions about difficulties in teaching and learning organic chemistry. They therefore suggest that further studies into how teachers’ perceptions influence their teaching and consequently their students’ experiences be carried out. In addition, in future research, a diagnostic test based on the topics in the SHS organic chemistry syllabus could be added to ascertain whether the perceived difficult topics are actually difficult for students to answer questions on. This would help teachers to separate perceived difficulties from the actual difficulties (realities) and be able to address them in their lessons.
Assessing secondary students’ scientific literacy: A comparative study of suburban schools in England and Malaysia
Authors:   School of Education, College of Business, Arts and Social Sciences, Brunel University London, United Kingdom, Mat Noor Mohd Syafiq Aiman
Published: November 2021

This study sought to assess the level of secondary students’ scientific literacy in suburban schools in Malaysia and England, a research area which to date has not been fully explored in the literature. The study analysed the data using the OECD’s three domain-specific competencies of scientific literacy, namely: i) explain phenomena scientifically, ii) evaluate and design scientific enquiry, and iii) interpret data and evidence scientifically. To assess the level of secondary students’ scientific literacy in these contexts, the study applied the scientific literacy assessment instrument called the ‘Nature of Scientific Literacy Test’ (NOSLiT), first developed by Wenning (2006). The results indicated that the level of scientific literacy of English students was higher than that of Malaysian students across all three domain-specific competencies. Despite the fact that NOSLiT is a systematic and reliable instrument for assessing the level of students’ scientific literacy, the study found that OECD’s three domain-specific competencies of scientific literacy provided better insights into the level of secondary students’ scientific literacy in Malaysian and English suburban schools. It is suggested that future studies should use a qualitative approach to both data collection and analysis to understand the level of students’ scientific literacy in more detail.

Kitab Undang – Undang Hukum Pidana (KUHP) Indonesia merupakan warisan negara jajahan. Wetboek van Strafrecht (WvS) tidak dapat dipungkiri bahwa aturan yang terdapat dalam kitab KUHP ini masih memiliki kekurangan dan belum mampu mengisi kokosongan hukum. Aturan pidana pokok dalam pasal 10 KUHP menyatakan pidana pokok berupa pidana mati, penjara, kurungan dan denda. Formulasi pasal pidana dalam hukum positif Indonesia memilik kecenderungan pada pidana pokok penjara. Dengan tidak seimbangnya pidana masuk dan pidana keluar mengakibatkan lembaga permasyarakatan mengalami overcapacity. Dengan terjadinya overcapacity lembaga permasyaratan membuat lembaga berwenang ini sulit untuk mampu memberikan hak – hak tahanan secara layak. Problematika ini menjadi ujian bagi penegak dan perumus undang – undang untuk melakukan pembaharuan hukum dengan studi perbandingan hukum pidana. Melalui perbandingan hukum pidana alternatif KUHP Indonesia dengan KUHP Jerman dikenal German Criminal Code menemukan metode alternatif pidana yakni denda harian (day fine) sebagai alternatif pemidanaan sebagai langkah mengantisipasi overcapacity lembaga permasyarakatan.

Since Covid 19 attacked Indonesia, almost all sectors have been affected. In the education sector, which requires students to study from home (online), in the economic sector the poverty rate is getting higher, many workers have been laid off and some are sent home. The face of the Indonesian economy has become a mess. One of the ways for the government to reduce the impact of the COVID-19 pandemic is to provide social assistance to the community. However, in distributing aid, the distributors are often constrained in prioritizing the recipient community. The mechanisms for distributing aid are complicated and often not well targeted due to inappropriate criteria for beneficiaries and inaccurate / inaccurate data. So that not a few people protested because they did not receive assistance even though they were also affected by the Covid 19 pandemic. The decision support system using the weighted product method was considered capable of finding the highest priority for beneficiaries based on predetermined criteria, namely employment status, home status, domicile, dependents. and income per month. The final result is a rating of vactor V where the alternative which has the highest value has the highest priority to receive assistance.

Published: November 2021

Background: We have previously reported that the Pathways to Comorbidity Care (PCC) training program for alcohol and other drug (AOD) clinicians improved identification of comorbidity, self-efficacy, and attitudes toward screening and monitoring of comorbidity. We aimed to identify barriers and facilitators of implementation of the PCC training program in drug and alcohol settings.

Methods: The PCC training program was implemented across 6 matched sites in Australia as per (1), and 20 clinicians received training. PCC training included seminar presentations, workshops conducted by local “clinical champions,” individual clinical supervision, and access to an online information portal. We examined barriers and facilitators of implementation according to the Consolidated Framework for Implementation Research.

Results: Barriers included inner setting (e.g., allocated time for learning) and characteristics of individuals (e.g., resistance). Facilitators included intervention characteristics (e.g., credible sources), inner setting (e.g., leadership), and outer setting domains (e.g., patient needs). Clinical champions were identified as an important component of the implementation process.

Conclusions: Barriers included limited specific allocated time for learning. A credible clinical supervisor, strong leadership engagement and an active clinical champion were found to be facilitators of the PCC training program.
Systematic Identification of Endogenous Retroviral Protein-Coding Genes Expressed in Canine Oral Malignant Melanoma
Authors: Kitao Koichi , Sumiyoshi Aoi , Nakagawa So , Matsumoto Yuki , Mizuno Takuya , Miyazawa Takayuki
Published: November 2021

Endogenous retroviruses (ERVs) are remnants of ancestral retroviruses that infected host germ cells in the past. Most ERVs are thought to be non-functional elements, but some ERVs retain open reading frames (ORFs) capable of expressing proteins. The proteins encoded by ERV-ORFs have potential roles in oncogenesis; however, studies on mammals other than humans and mice are limited. Here, we identified ERV-derived genes expressed in canine oral malignant melanoma (OMM). We identified 11 ERV-derived genes in our OMM samples. Differential expression gene analysis revealed that four ERV-derived genes (PEG10, LOC102155597, and two newly identified genes) were upregulated in OMM compared to healthy tissues. PEG10 is a conserved long terminal repeat (LTR)-type retrotransposon-derived gene among mammals and is involved in human cancers. LOC102155597 is a retroviral env gene conserved in Carnivora. This Env protein harbors an immunosuppressive domain, implying the potential adverse effects on the immune system. While the production of viral particles from ERVs has been reported in human and mouse melanoma, we found no ERV-derived genes having the potential to produce viral particles. These results provide insights into the different and conserved features of ERV-derived genes in mammalian melanoma.

Este pequeno livro é uma contribuição para a genealogia contemporânea do que se convencionou chamar trabalho sujo. Mais especificamente, é um comentário da noção de “trabalho do mal” elaborada por assim dizer a quatro mãos por Christophe Dejours e Joseph Torrente a partir de uma visão histórica do Holocausto, baseada na descoberta da experiência coletiva do “trabalho atroz” como chave explicativa da destruição dos judeus na Europa. Em resumo, a revelação de como o horror do Terceiro Reich deriva da imposição do genocídio como um trabalho de massa realizado por uma legião de colaboradores zelosos. Uma hipótese até então adormecida na melhor historiografia que precisou esperar a intensificação do sofrimento social pelo trabalho sujo do neoliberalismo hoje para enfim despertar e sugerir este curto-circuito explosivo num verdadeiro diagnóstico de época.

PROBLEMS OF FOREST ENGINEERING AND DIRECTIONS OF THEIR SOLUTION
Authors: Sakhanov V. , Fitchin A.
Published: November 2021

A high dependence on imports is observed in the segment of forest machine- building products. The volume of production of logging machines and woodworking equipment remains insufficient – both in terms of the number of manufactured equipment and its consumer properties. The main problem of domestic mechanical engineering remains low competitiveness in relation to products manufactured by leading foreign companies.
The lack of competitiveness of the domestic forest machine building is largely due to the lack of funds for the technical and technological renewal of production at the majority of enterprises. Sectoral research institutes, previously engaged in the development of technologies and equipment for timber industry enterprises and companies, have practically ceased their scientific and design activities. In these conditions, the innovative development of the timber industry complex is mainly carried out on the basis of the acquisition of imported equipment. The share of imported machinery and equipment of domestic production is more than 90 percent.
The solution to this problem requires serious systemic measures in the implementation of technical policy in the forestry sector of the country’s economy. The strategy for the development of the forestry complex until 2030 provides for the creation of at least 3 research consortia – innovative and technical centers corresponding to the world level, on the basis of which the coordination of scientific research, the creation of technologies and equipment for logging, woodworking and the production of pulp and paper products. The article formulates a number of proposals on measures of state support for the domestic forest machine building.
FORESTRY PRINCIPLES AND LOGISTICS IN THE SPHERE OF REPRODUCTION OF OAK FORESTS IN THE CENTRAL BLACK EARTH
Authors: Chernyshov Mikhail
Published: November 2021

The reproduction of forests is long-term. A complex and multifaceted silvicultural and technological process taking place in the conditions of disordered economic human activity and global warming. Reproduction of oak forests in the Central Black Earth Region, which are the cradle of Russian ship oak forests, has a regional specificity, which consists in the fact that in most forestries it is carried out mainly through artificial reforestation and sometimes combined. The reason is the complete absence of natural seed regeneration of oak under the canopy of mature and over-mature stands entering clear and selective sanitary felling.Even in narrow-cut and clear- cut areas, including those cultivated in accordance with the current requirements of the “Regulations for reforestation”, there is an intensive change of the main forest-forming species (pedunculate oak, common ash and Norway maple) to accompanying and less valuable (aspen, willow, birch , linden, hazel, etc.).On the basis of generalization of the long-term experience of the forestries of the region, logistics and silvicultural principles of sustainable-expanded, program- targeted and effective reproduction of oak forests are proposed and scientifically substantiated, without strict adherence to which, in practice, it is impossible to grow new durable high-quality, sustainable and highly productive oak forests with given target taxation characteristics. A step-by- step algorithm of sustainably expanded reproduction of oak forests of the future is considered. Prospects, ways and methods of high-quality and sustainably expanded reproduction of oak forests in the forestries of the Central Chernozem region have been determined.The prospects, ways and methods of high-quality and sustainably expanded reproduction of oak forests in the forestries of the Central Chernozem region have been determined. Controlled natural seed and artificial methods with the obligatory timely and high-quality agrotechnical and silvicultural maintenance, preventing the drowning of the pedunculate oak by other, faster-growing species, should become priority.

JUSTIFICATION OF GEOMETRIC PARAMETERS OF A MOBILE SMALL-SIZED WAY FOR TRANSSHIPMENT OF TIMBER CARGO
Authors: Chuprakov V. , Posypanov S.
Published: November 2021

The volumes of relatively inexpensive ship transportation of wood raw materials can be significantly increased by more actively using middle rivers for these purposes. However, the existing technologies for loading timber onto ships do not allow this. To solve the problem, the design of a mobile small-sized pier and the corresponding technologies for transshipment of timber cargo using logging equipment have been proposed. The design of a mobile berth involves the substantiation of its geometric parameters. In this regard, using the graphic-analytical method, recommendations are given, and empirical dependences are proposed for calculating the calculated values of the ship’s draft, the width and length of the loader, on which the indicated parameters of the mobile pier depend. The recommended value of the angle between the lower and upper surfaces of the berth α, as well as between the aft surface and the vertical B. A general algorithm for calculating the geometric parameters of a mobile pier is proposed. Using this algorithm, for example, the geometric parameters of the berth designed for loading timber onto barges on the middle rivers of the North Dvina basin during the flood period were determined. The pier height is
2.8 m, the length is 9.0 m, the width is 5.0 m, the height in the bow is 0.42 m, the length of the coastal ramp is 1.46 m, angles α=16gr, B =15gr.

Low bearing capacity of soils, thin easily vulnerable soil cover determine the need to take into account soil and soil conditions, damage to the fertile layer from the impact of technology in the process of planning the spatial and temporal placement of logging and designing transport and technological processes in order to preserve conditions for reforestation and preserve biodiversity. Taking the stability of forest soils and soils, when exposed to logging and forestry equipment, the ability to regenerate the soil and restore conditions for natural reforestation, the forests of the European-Ural region are divided into five classes. The main indicators of the classification of the resistance of forest soils and soils to the technological process of logging are deformability, compaction, fertility and reforestation capacity of soils. The low quality of logging highways with a high axle load and an increase in logging volumes requires a more accelerated development of the industry of road-building materials and products, designed for maximum mechanization and industrialization of their production. A prefabricated pavement slab (PSP) made of asphalt concrete, reinforced with at least two layers of polymer reinforcement, can be manufactured in an industrial environment subject to all the required technological standards and conditions, which will allow setting the required strength characteristics.
