Differential expression of STAT5B in cancer of the skin: malignant melanoma.
Authors: Mamoor Shahan
Published: May 2023

Skin cancer is diagnosed in nearly 1.5 million patients each year (1). While patients with basal and squamous cell carcinomas are provided with 5-year survival rates at nearly 100% and 90%, respectively, patients diagnosed with cutaneous melanoma (metastatic melanoma) are provided 5-year survival rates at 91.4% at stage I and 24.6% at stage IV (2-5). We mined published microarray datasets (6, 7) to determine in an unbiased fashion and at the level of the transcriptome genes most differentially expressed in the primary tumors of patients with the deadliest type of skin cancer, malignant melanoma. We found significant differential expression of the gene encoding signal transducer and activator of transcription 5B, STAT5B, when comparing melanoma tumor tissue from the human skin to the tissue of origin. STAT5B mRNA was present at significantly lower quantities in melanoma tissues as compared to normal tissues from the skin. Analysis of human survival data revealed that expression of STAT5B in melanoma tissues was correlated with overall survival in patients with malignant melanoma. STAT5B expression changes may be important for the initiation or progression of malignant melanoma in humans.

How Studying Community Colleges Impacts Learners: Reducing Community College Stigma and Improving Community College Advocacy
Authors: Nguyen David Van
Published: May 2023

This study evaluated a speaker series of community college studies presentations. The seven monthly presentations were led by professors and an institutional researcher who conduct research on community colleges. Example presentation topics included the history of community colleges, policy reforms in community college developmental education, and transfer receptive culture. The presentations’ primary audience was community college students. I interviewed 12 community college student attendees and then analyzed interview transcripts using structural coding and thematic analysis. Two themes were identified. The first theme was that the presentations improved most students’ perceptions of community colleges. To elaborate, the presentations destigmatized community colleges and dismantled a deficit thinking paradigm. The second theme was that the presentations improved most students’ interest and ability in community college advocacy. For example, several attendees informally shared the knowledge they gained from the presentations to empower their community college peers. Furthermore, several attendees became more effective advocates within formal institutional positions such as student advisory group member, office assistant, or peer advisor. These findings align with past research that suggests that community college studies can improve learners’ perceptions and advocacy around community colleges.
Istoria eugeniei
Authors: Sfetcu Nicolae
Published: May 2023

Sir Francis Galton a sistematizat aceste idei și practici despre eugenie, influențat de cartea Originea Speciilor a vărului lui, Charles Darwin, prin care mecanismele de selecție naturală au fost potențial zădărnicite de civilizația umană. El a afirmat că societatea umană, protejând pe cei defavorizați și slabi, era în contradicție cu selecția naturală , și numai prin schimbarea acestor politici sociale ar putea fi salvată societatea de la o „revenirea spre mediocritate”, frază transformată de el ulterior în „regresia spre mediocritatea.” Charles Davenport, un om de știință din Statele Unite, a inițiat o mișcare eugenică mondială implementată în multe țări.
Identifying Teacher Salary Spiking and Assessing the Impact of Pensionable Compensation Reforms in Illinois
Authors: Goldhaber Dan , Grout Cyrus , Holden Kristian L.
Published: May 2023

Defined benefit (DB) pension plans incentivize “salary spiking,” where sharp increases in pay are leveraged into significantly higher levels of retirement compensation. While egregious instances of salary spiking occasionally make headlines, there is little guidance on the definition of salary-spiking behavior or understanding of its prevalence. We develop empirical methods to quantify the prevalence of salary spiking by identifying cases where end-of-career compensation deviates from the expected level of compensation. We apply this method to teacher pension systems in Illinois to assess the prevalence of salary spiking before and after the implementation of a reform designed to dissuade salary spiking.
Magneto-Optical Sensors Accurately Analyze Magnetic Field Distribution of Magnetic Materials
Authors: Koschny Marco , Lindner Morris
Published: May 2023

In 1845, Michael Faraday discovered that light passing through a transparent medium can be altered with an externally applied magnetic field. It is not surprising, given the science and engineering involved, that the ideal medium for observing the Faraday effect and the process by which it is made have only recently been developed. This article explains how magneto-optical sensors make use of advanced materials and processes to harness the Faraday effect, making it possible to see magnetic fields and domains with detailed resolution and instantly obtain flux density measurements over the surface of magnetic materials and magnetized parts.

Authors: Pellegrino Sergio
Published: May 2023

Self-deployable booms made of flexible composites have been successfully used on spacecraft and are currently being designed into future satellite missions. Structures of this type have been proposed for decades, but their use has been limited by the difficulty of predicting their behavior in zero gravity conditions. It is now possible, however, to realistically simulate the operation of such structures using FEA software and micromechanical modeling. This article explains how boom designs for satellites are being refined using simulation data and validated by physical testing.

Authors: Méndiz-Noguero Alfonso , Wennberg-Capellades Laia , Regadera-González Elisa , Goni-Fuste Blanca
Published: May 2023

The expansion of the Covid-19 virus in early 2020 grew in parallel with the spread of rumours, false or unverified news and even contradictions between information sources and health sources. It has been the first pandemic to be broadcast live on social media and has generated disinformation which was described by the WHO as an “infodemic”, a pandemic as serious as the virus itself. The aim was to identify and analyse the impact generated by the first wave of Covid-19 (January-June 2020) on public health communication. The review was carried out under the Prisma guidelines. A systematic search was performed in PubMed, Scopus and Web of Science databases, which yielded a figure of 1.157 papers. Using seven keywords as a filter a corpus of 193 articles was reached. Four main themes were identified: 1) Need for massive public health literacy; 2) Social networks as an information and disinformation during pandemic; (3) The uncertain response of institutional communication; and (4) Media coverage of the pandemic. The authors propose large-scale health literacy and point out the need to work on health information together -governments, health institutions and the media-.
Using the “mind map” method in the development of students’ vocabulary in English
Authors:   Khoja Akhmet Yassawi International Kazakh-Turkish University, Turkestan, Meirbekov A.K. , Abzhekenova B.G.
Published: May 2023

This article is devoted to the “mind map” method of developing the vocabulary of students in English. In the process of learning a language, the main principle before developing language skills is the development of vocabulary since insufficient vocabulary limits the capabilities of students. It also reduces the student’s activity and interest during the lesson. Improving the quality of education requires the development of a work plan in accordance with the level of education, the interests and values of students, taking into account each level. It is also important to use effective methods to improve the quality of students’ knowledge. Thus, this article aims to learn vocabulary easily using the “mind map” and to make it possible to reuse previously used words using the “mind map”. During the study, a review of the literature on this topic was conducted. As a result, vocabulary development through the “mind map” is presented as a method for improving the effectiveness of the educational process.

Published: May 2023

A study about teaching competencies is discussed in various scientific research around the world. Especially it takes its momentum during the pandemic period. An approximation of the competencies advocating excellent and effective teaching profiles should be put into practice by linguistic education teachers. To achieve this goal, two actions were taken: a review of the frameworks for professional teaching generally and the role of teachers’ lab-based teaching showing their competencies to teach the English language at general education establishments in Kazakhstan. The recent pandemic period showed the relevant need to upgrade teachers’ qualifications and self-development. An observation of the conditions of the soft model realization was tested by research conducted by the authors. The conditions of three types were presented: content-activity, organizational-managerial, and the ability to transform the conditions of the first and second types for professional development of the teachers. The world keeps an extreme pace of remote-classroom activities nowadays, therefore it demands a model of a teacher who can adapt to changes and display creative leadership while building reciprocal relationships with learners throughout the teaching-learning process.

Authors:   Академик Е.А. Бөкетов атындағы Қарағанды университеті, Қосыбаева У.А
Published: May 2023

The article deals with the creation of intelligent systems and the relationship between the human mind and the computer. The authors highlight the importance of artificial intelligence today. The relationship of the information society with the education sector, which is of great importance today, shows that the process of “technologization” is gaining strength owing to development. Thus, it is important to improve teaching methods, use new methods based on special pedagogical research in theory and practice, and create optimal conditions for practical work, special educational materials, software and technological products aimed at realizing the potential of information and communication technologies. The authors describe the importance of using special computer programs in the development of students’ knowledge and skills. In addition to traditional teaching in the education system, teaching with the use of special computer programs allows a deeper study of the specifics of each subject. However, most of these educational programs provide an opportunity to make choices based on their knowledge in this area. The authors also analyze expert systems based on teaching in this area in higher education and the topics of special courses introduced into it. In the conclusion on the chosen topic in the disciplines taught in the specialties of the university, the authors indicate the volume of the topic, which will be continued in the future.

This article reveals the problem of the use of digital educational technologies in foreign language teaching and presents the educational possibilities of using these technologies in the process of learning and teaching various aspects of foreign language. The teacher can use the digital environment and distance learning as part of the blended learning model or as the main form of learning if this is provided for by the curriculum of the educational institution. When using this form of teaching a foreign language, the undoubted advantage is the flexibility of the learning process, since to the extent that the skills and level of knowledge of the student are taken into account, it is possible to establish an individual approach and teaching methods, as well as the methods, time and duration of studying the material. The authors conducted an experiment among students and undergraduates of the Faculty of Foreign Languages to identify the relevance of the use of digital technologies in the conditions of distance education in higher education. The survey was conducted remotely using the survio.com website.

Published: May 2023

The authors consider interactive teaching aids as a motivational stimulus in preparing students for future professional activities using the example of the electronic educational and methodological manual “Professionally oriented English. Biology”. This manual was developed directly for the preparation of students of pedagogical specialties, namely students of the specialty 6B01509 — Biology, to use English in their professional activities in the conditions of modernization of education in the Republic of Kazakhstan. The relevance of the use of English in professional activities by students of pedagogical specialties is determined by the systematic transition to teaching in Kazakh, Russian, and English the subjects of the natural and mathematical cycle of general education schools. The increasing demand for the English language as a result of this, a significant expansion of the possibilities of its practical application, makes it a means of improving the professional activity of a highly qualified specialist. However, for the successful implementation of the trilingual initiative, it is important not only to target the training of students of pedagogical specialties of the university, but also to develop methodological and scientific-methodological support. In the course of the conducted pedagogical research using a combination of various incentives in various forms and methods of conducting classes that encourage students to active educational and cognitive activities, creating situations of professional foreign language communication and a positive emotional atmosphere in the preparation process, there is a positive trend in the formation of the motivational component of the readiness of students of pedagogical specialties to use English in professional activities.

Modeling is one of the key categories of modern cognitive theory and design-engineering practice. Simulation and visualization of real physical processes and phenomena are important technological tools and simulation results. The article presents a comparative review and analysis of existing emulators, such as Cisco Packet Tracer and UNetLab, as well as the rationale for choosing CupCarbon as a platform for modeling, in particular, wireless networks for the Internet of Things. The functional potential of today’s most common emulators like Cisco Packet Tracer and UNetLab are significant. Cisco Packet Tracer is a powerful software emulator, which gives the possibility to users to simulate networks, organizing them with the almost unlimited number of devices, using the equipment and adjusting it for the specific tasks of this or that environment. The program gives the opportunity to develop the quality of decision-making speed, creativity and critical thinking, configuration and troubleshooting networks with the use of virtual equipment and simulated connection. Despite the great advantages of this software emulator, it has several disadvantages, which make it incorrect for modeling IoT networks, such as the lack of simulation in a 2D/3D environment and adding urban and natural noise, not a complete emulation of IOS, almost everything that goes beyond the CCNA, it also cannot be built on it, the possible manifestation of a variety of bugs that are treated only by restarting the program.

Published: May 2023

The article highlights the results of a study devoted to the development of universal metacognitive skills. The main purpose of the work is the development of students’ metacognitive skills. An attempt to integrate metacognitive instructions into the learning environment and the preparation of instructions suitable for a particular learning environment have brought certain results. Metacognitive instruction is conducted outside of disciplines, the research is focused on universal, interdisciplinary metacognitive skills of students and their development. The participants are 29 students of 1-st year of the educational program “Psychology” of the M.H. Dulaty Taraz Regional University, who studied in a blended format because of the pandemic. The first instruction of the study — the formation of ideas about metacognition among students is based on the theoretical conclusions of scientists who conducted research on metacognition, the second instruction — setting goals in the study of disciplines by students, is based on the well-known traditional method of developing metacognition — structured written reflection, the third — “What approach to learning do you use?” — the methodology developed by the Edinburgh Center for Research in Teaching and Instruction, translated into Kazakh. The study results confirm the conclusions of studies by foreign authors that the development of metacognitive skills is more effective when accompanied by a cognitive component. The most useful and effective instruction among the three listed, we can call setting goals in the study of disciplines among students. The general conclusion of the study is the conditionality and necessity of metacognitive instructions among 1st-year students.

The active development and application of new digital technologies in education, on the one hand, has opened up new opportunities for improving the efficiency of the university’s business process management. On the other hand, this has led to a significant increase in security threats and the vulnerability of educational institutions to cyber criminals. The recent rapid growth of various incidents regarding cybercrimes shows the insufficiency of traditional approaches to information security. Consequently, information security risk assessment has become an important task for most educational institutions. Several models have been proposed to help educational institutions solve problems with building information security. This article proposes a new hierarchical structured model for assessing information security risks in educational institutions using fuzzy logic. A new method for assessing information security risks is also described using the example of automated control systems or ERP systems (for example, training management systems). The proposed risk assessment of the university was modeled using fuzzy logic in the form of 15 fuzzy machines. In the course of a number of experiments, we carefully studied the assessment of information security risks of various software products used in universities. The proposed method should solve the problem of flexible risk assessment.

Questão do intelecto na formação do “mestre”
Authors: De França Martins Isabella Carolina , Oliveira Terezinha
Published: May 2023

O objetivo deste artigo é analisar o conceito de intelecto apresentado na questão 79 da Suma Teológica com a contribuição do livro A unidade do intelecto contra os Averroístas, a fim de entendê-lo como um conceito perene que nos permite refletir sobre a aprendizagem do ser humano contemporâneo. Para Tomás de Aquino era imprescindível que seus alunos compreendessem o intelecto de modo que contribuísse no processo de ensino quando, futuramente, se tornassem mestres. O intelecto, para ele, era essencial para definir o ser humano como uma espécie capaz de descobrir, aprender e ser responsável por suas ações. Nosso estudo teve como fio condutor a História Social (BLOCH, 2001; BRAUDEL, 1992; LE GOFF, 1990), que considera que os acontecimentos sociais são oriundos das constantes mudanças econômicas, sociais e políticas. A pesquisa possibilitou observar que a concepção de intelecto de Aquino possui princípios essenciais para entendermos o homem como um ser dotado de potencialidade intelectiva.

A Formação Docente – Revista Brasileira de Pesquisa sobre Formação de Professores (RBPFP) – é uma publicação do Grupo de Trabalho Formação de Professores (GT8), da Associação Nacional de Pós-Graduação e Pesquisa em Educação (Anped), publicada em parceria com Editora Autêntica. Esta edição refere-se ao primeiro quadrimestre de 2023 – volume 15, número 32 (janeiro-abril) de 2023.
Apresentamos aos pesquisadores do campo e ao público leitor em geral este primeiro número da revista do ano de 2023.  Aproveitamos a oportunidade para nos desculpar pelo atraso da publicação deste quadrimestre justificada em virtude de dificuldades no processo de edição. 
Publicamos o volume 15 com o número 32 da revista divulgando nove (9) pesquisa publicando seus resultados em artigos de demanda espontânea, assim distribuídos: (nordeste =3; sul=3; centro-oeste=2 e sudeste=1) Os três (3) artigos da região nordeste trazem a discussão sobre a formação inicial e questões da docência. No primeiro uma análise sobre a Formação Inicial por meio do PIBID. Tratando do mesmo tema da formação inicial apresenta-se um segundo artigo sobre a interdisciplinaridade na prática de ensino de ciência, e o terceiro artigo que discute as motivações da formação para a docência na área da Física; Da região sul também se publica três (3) artigos todos sobre fundamentos da formação. O primeiro - “formação do mestre, uma leitura tomasiana” traz uma discussão filosófica para a Formação de Professores, tema bastante raro em nosso campo de estudos pela primazia da epistemologia da prática. Seguido de um artigo que nos propõe um debate sobre o tema da Pedagogia como Ciência, na perspectiva e leitura das universidades do sul do país. E, o terceiro deste regão elabora uma revisão sistemática sobre aprendizagem de conceitos na formação inicial de professores; Da região Centro Oeste publicamos dois (2) artigos, um sobre Formação Continuada na perspectiva do trabalho docente no planejamento coletivo e colaborativo na área de ciências, e o segundo, uma análise de reflexões sobre a Formação Inicial em trabalhos finais de curso na licenciatura de Educação Física. E por fim, algo bastante diferenciado e que foge a regra, a publicação de um único artigo do sudeste, no qual os autores tratam também de questões teórico-metodológica: “Uso de categorias analíticas para a descrição de crenças epistemológicas de professores em formação”. Este fato foi bastante inusitado uma vez que nos demais números, e na história da revista, o maior volume de submissões vem da região sudeste. Talvez este fato seja um tema interessante para pensarmos que a maior amplitude de periódicos na área e as propostas de maior atenção a dispersão regional começam a surtir efeitos, possibilitando assim, maior democratização na pesquisa nacional. 
Esperamos que este número proporcione um relevante aporte para os/as pesquisadores(as) do campo da formação de professores.
Prediction of bubble size in Bubble columns using Artificial Neural Network
Authors: Sadoon Ahmed zeki Nada
Published: May 2023

In the literature, several correlations have been proposed for bubble size prediction in bubble columns. However these correlations fail to predict bubble diameter over a wide range of conditions. Based on a data bank of around 230 measurements collected from the open literature, a correlation for bubble sizes in the homogenous region in bubble columns was derived using Artificial Neural Network (ANN) modeling. The bubble diameter was found to be a function of six parameters: gas velocity, column diameter, diameter of orifice, liquid density, liquid viscosity and liquid surface tension. Statistical analysis showed that the proposed correlation has an Average Absolute Relative Error (AARE) of 7.3 % and correlation coefficient of 92.2%. A comparison with selected correlations in the literature showed that the developed ANN correlation noticeably improved the prediction of bubble sizes. The developed correlation also shows better prediction over a wide range of operation parameters in bubble columns.

A common field development task is the object of the present research by specifying the best location of new horizontal re-entry wells within AB unit of South Rumaila Oil Field. One of the key parameters in the success of a new well is the well location in the reservoir, especially when there are several wells are planned to be drilled from the existing wells. This paper demonstrates an application of neural network with reservoir simulation technique as decision tool. A fully trained predictive artificial feed forward neural network (FFNNW) with efficient selection of horizontal re-entry wells location in AB unit has been carried out with maintaining a reasonable accuracy. Sets of available input data were collected from the exploited grids and used in the training and testing of the used network. A comparison between the calculated and observed cumulative oil production has been carried out through the testing steps of the constructed ANN, an absolute average percentage error of the used network was reached to 4.044%, and this is consider to be an acceptable limit within engineering applications, in addition to that, a good behavior was reached with (FFNNW) and suitable re-entry wells location were identified according to the reservoir configuration (pressure and saturation distribution) output from SRF simulation model at the end of 2005.

In order to reduce the losses due to evaporation in the stored crude oil and minimizing the decrease in °API many affecting parameters were studied (i.e. Different storage system, namely batch system with different types of storage tanks under different temperatures and:or different pressures). Continuous circulation storage system was also studied. It was found that increasing pressure of the inert gas from 1 bar to 8 bar over the surface of the crude oil will decrease the percentage losses due to evaporation by (0.016%) and decrease the change of °API by (0.9) during 96 hours storage time. Similarly using covering by surfactant (potassium oleate) or using polymer (polyurethane foam) decreases the percentage evaporation losses compared with uncovered surface of the blend crude oil. In each surfactants and polymers the layer thickness was (1.0, 1.5, 2.0, 2.5, 3.0 cm), and increasing the thickness of the surfactant to 2.5 cm or of the polymer to 3 cm was found to be best required thickness. Surfactant gave lower percentage evaporation losses than polymer, for fixed roof tank (i.e. 0.299%, 0.383%) for 120 hours evaporation time. Different processed storage tanks namely (fixed roof, external moving roof, fixed and internal moving) were studied and fixed and moving roof was the best in reducing evaporation losses (0.453%) for 120 hours. In continuous circulation for proposed continuous storage system, the percentage evaporation losses for covered with surfactant, covered with polymer, and uncovered surface of blend crude oil were (0.328%), (0.378%), and (0.45%) respectively at 24 °C for 96 hours evaporation time.
Methanol Effect on color stability and shelf life of phenolic Resin compound under acidic conditions

The object of this work is to investigate the effect of the addition of methanol on the shelf life and color characteristics of novolak resin. Different percentages were added and two mechanisms were suggested for the addition. High ortho structure (1, 2-3) novolak resin was prepared and used in the above investigation. Experimental determination using FT-IR and UV-spectroscopy showed that on the addition of 30% of methanol and according to the second mechanism of addition novolak shelf life increased to 12 months without obvious decomposition and color change. It is suggested that methanol plays an important role in the inhabitation of the reactive sites on the resin that are responsible for the oxidation of the polymer when exposed to atmospheric or storage conditions.

The purpose of this study is to investigate the mediating effect of social support on the influence of positive psychological capital on happiness in middle-aged women engaged in the emotional service industry. To this end, a survey was conducted on middle-aged women (40s-50s) engaged in the appraisal service industry nationwide for 6 days from December 17 to 22, 2022, and as a result, 300 valid surveys were used in this research analysis. As a result of the analysis, first, it was analyzed that the higher the positive psychological capital, the greater the positive (+) effect on happiness. Second, social support was analyzed to have a significant positive (+) effect on happiness. Third, the mediating action of social support between positive psychological capital and happiness was found to be significant. In other words, it was shown that the mediating explanatory power of social support had a very significant effect on the influence relationship between positive psychological capital and happiness. These results show the necessity of preparing policies through strengthening relationships with family and friends and forming social consensus to support them in order for the positive psychological capital of middle-aged women engaged in the emotional service industry to be the driving force of social support to increase happiness. Based on these research results, the theoretical and practical implications of social support to improve the happiness of middle-aged women engaged in the emotional service industry were presented.

Probleme der sozial-ökologischen Klassenanalyse und die Grenzen des Umweltbewusstseins
Authors: Rackwitz Hans
Published: May 2023

Der Beitrag diskutiert kritisch die Limitierungen der Bourdieuschen Klassenanalyse sozial-ökologischer Mentalitäten, die Dennis Eversberg in der PROKLA 210 vorgestellt hat. Es wird argumentiert, dass sein Ansatz den Vielschichtigkeiten und Widersprüchlichkeiten von Bewusstseinsformen nicht gerecht werden kann und analytisch auf der Zirkulationsebene verbleibt, während die Arbeits- und Betriebssphäre weitestgehend ausgeklammert wird. Diese Kritik schließt mit einem Plädoyer für eine ökosozialistische Klassenpolitik, die eine sozial-ökologisch transformative Politik statt von Einstellungsmustern und Positionen im sozialen Raum von einem Standpunkt der Arbeit her denkt.

In diesem Beitrag stellen wir die Bedeutung einer psychoanalytisch-sozialpsychologischen Perspektive auf die Klimakrise für eine sozial-ökologische Transformationsstrategie heraus. Dabei fokussieren wir exemplarisch auf den Zusammenhang von Entfremdung, Ressentiment und Klimaangst, um den erkenntnisreichen Dialog zwischen kritischer Klimapsychologie einerseits und der ideengeschichtlichen Tradition der marxistischen Kapitalismuskritik andererseits her- und darzustellen.
Editorial: Tarifvertrag
Authors: Beckmann Martin , Schmidt Rudi , Syrovatka Felix
Published: May 2023

Der Niedergang des deutschen Systems kollektiver Arbeitsbeziehungen ist ein altes und viel beschriebenes Phänomen. Spätestens seit den 1990er-Jahren hat sich im Zuge des neoliberalen Umbaus eine Abwärtsdynamik entfaltet, die bis heute anhält. Das Editorial untersucht dabei den allgemeinen Rückgang der Tarifbindung mit den sektoralen Unterschieden. Ein Blick in die Geschichte der Tarifautonomie fördert mehr zutage als das gängige Klischee einer heroischen Kampfzeit in der Prosperitätsphase der 1950er- bis 1970er-Jahre, der eine defensive Anpassungsphase unter Globalisierungsdruck gefolgt sei. So erweitert sich das Bild noch einmal, wenn man die gesamten ca. 150 Jahre Tarifgeschichte der deutschen Gewerkschaften in den Blick nimmt. Das Editorial zeigt auch die vielfältigen Ursachen für die sinkende Tarifbindung und die abnehmende Bedeutung des Flächentarifvertrags auf und beleuchtet die ambivalenten arbeitsrechtlichen Entwicklungen.
