Published: January 2022

In today's economy, it is necessary to explore the environmental impact of mining. Coal mining greatly affects all environmental parameters of the environment: home, production, hydrodynamics. The environmental situation in the area of the mining company can be changed if environmental contamination is monitored and environmental protection plans and measures are developed. The purpose of this work is the analysis of systems and models of these processes in the ecosystem. The main systemic hypothesis of the research is that the variety of criteria and methods of risk assessment is a necessary condition of order in the system. The main results of the work are the following: 1) a systematic analysis of the problems of environmental security, geodynamics of the mining areas, aspects of the balance of the sustainable process and the cause of the increase in danger was carried out; 2) Proposed approaches (models) for the assessment of evolutionary ecological potential and health risks, as well as adaptive situational modeling of the ecosystem. It is important to note, the study results do not suggest complex environmental monitoring studies.
Dirac’s Refined Unification of Quantum Mechanics and Special Relativity: An Intertheoretic Context
Authors: Nugayev Rinat M.
Published: January 2022

One of the key episodes of history of modern physics – Paul Dirac’s startling contrivance of the relativistic theory of the electron – is elicited in the context of lucid epistemological model of mature theory change. The peculiar character of Dirac’s synthesis of special relativity and quantum mechanics is revealed by comparison with Einstein’s sophisticated methodology of the General Relativity contrivance. The subtle structure of Dirac’s scientific research program and first and foremost the odd principles that put up its powerful heuristics is scrutinized with special emphasis on the highly controversial tenet of “mathematical beauty.” It is contended that despite the relentless Dirac’s remarks denigrating the controversial role of philosophy one can trace its indirect influence through Arthur Eddington’s and Hermann Weyl’s whimsical mathematical models. Accordingly, the milestones of Dirac’s research programme realization in the distinctive context of the applied epistemological doctrine are indicated.

Dissolution of Racial Boundaries
Authors: Knaus Juliann
Published: January 2022

As the field of mixed-race studies continues to expand, my article adds to this growth by analyzing the representation of mixed-race children in Natasha Trethewey's Thrall in relation to the corresponding Mexican casta paintings she refers to. I explore how Trethewey uses diction and etymology in Thrall by performing close readings of her Mexican casta painting poems. Throughout my analysis, I pay special attention to how aspects of knowledge and colonialism affect the portrayal of these mixed-race offspring. The aim of this article is to demonstrate that Trethewey skillfully uses diction and etymology to emphasize the relationship between knowledge and power, particularly with regard to the representation of mixed-race people in society. Trethewey intertwines mixed-race representation and experiences that seem disparate—her poems cross geographical, temporal, and spatial boundaries—in order to illustrate how mixed-race peoples' positioning and representation in society often transcends such boundaries while additionally critically assessing power dynamics controlling said representation. Accordingly, by closely examining the representation of mixed-race people and miscegenation in art and poetry, this article sheds a new light on how meaning can be developed between races and cultures and stresses how colonialism and knowledge can be connected to contextualizing difference across time and space.
The Impact of the Upgrading of High-tech Zones on the Total Factor Productivity of Enterprises: Evidence from Guasi-natural Experiments
Authors: Yang Weiwei , Kang Jiaru Kang , Ge Zhiyuan
Published: January 2022

Abstract

High-tech Zones are widely regarded as an effective mechanism to promote
innovation and development of industrial clusters and new ventures. As a change in
the external institutional environment, the upgrading of Provincial High-tech Zones
promotes the ‘metabolism’ of enterprises in the High-tech Zones. This paper regards
the upgrading of Provincial High-tech Zones as an external policy impact,
constructs a quasi-natural experiment to evaluate the micro-policy effect of
upgrading the Provincial High-tech Zones to the National High-tech Zones. Based
on the data of enterprises in High-tech zones from 2005 to 2014, this paper uses
Propensity Score Matching and Difference-in-Difference methods to analyze the
impact of the upgrading of Provincial High-tech Zones on the total factor
productivity of enterprises and explores the mechanism of action between the two
through the mediation effect model. The results show that the upgrading of
Provincial High-tech Zones distorted the total factor productivity of enterprises.
Besides, compared with state-owned enterprises, the upgrading of Provincial Hightech Zones has a greater impact on the total factor productivity of non-state-owned
enterprises. From the perspective of the intensity of government intervention, the
higher the intensity of local government intervention, the greater the distortion
effect. Further analysis shows that this distortion effect comes from adverse
selection and moral hazard caused by information asymmetry between government
and enterprises. The research results of this paper provide a realistic basis for the
development of enterprises located in the newly upgraded National High-tech Zones.

Neoliberalismo “à brasileira”: “quem tem tudo menos cor, onde cor importa demais”
Authors: Rodrigues Silva Caroline , Rodrigues Silva Louise , Rodrigues Silva Filipe
Published: January 2022

Esse ensaio teórico buscou refletir sobre o neoliberalismo contemporâneo. A partir da história do Brasil, intersecionada por opressões, as quais foram, sistematicamente, engendradas e convergiram em estruturas racistas, capitalistas e heterocispatriarcais. Iniciamos com a reflexão de que, mesmo o capitalismo, seguindo uma lógica, é diferenciado pelo processo histórico nos modos de produção e na acumulação primitiva situados no espaço e no tempo. O fio condutor historiográfico permitiu uma viagem resgate ao passado, não tão distante, até o contemporâneo. Foi negritado o modelo neoliberal e a eminente política da morte   para a sociedade não considerada produtiva nos moldes neoliberalista brasileiro. Por fim, perguntas reflexivas foram expostas a fim de provocar novos pensares dos e nos estudos organizacionais, além de propostas de novas abordagens para estudos futuros. O estudo contribui para o campo dos estudos organizacionais ao reconstruir um processo         histórico silenciado e ao problematizar perspectivas hegemônicas em administração, as quais são importadas de outros contextos sócio históricos de maneira acrítica e a-histórica, o que contribui para a manutenção da colonização do poder/saber.

The impact of the new identities of Covid-19 such as confirmed as positively infected, conducted self-isolation, stimulate intolerant attitudes in society. The public's attitudes towards the Covid-19 cases are very substantially contrary to the values in a multicultural society. The panic buying of medical equipment, medicines and vitamins, refusing the Covid-19 burial protocols even for medical personnel. This activity is an integration of multicultural education courses with community service. The purpose of this activity is to promote a campaign for individual identity, empathy, critical thinking, equal interaction, cooperative interaction, openness, and different status elimination. Videos are given directly to the community and through social media as the campaign process. In preparation and implementation, lecturers are assisted by students to create innovative media related to the current situation. There are 10 groups that produce media, in the form of animated videos. Before the media is used, there is a product evaluation by lecturers and classmates. After the revision, the media is used to conduct a multicultural campaign in the society. As a result of this activity, more than 1000 people who were exposed to the campaign, almost all considered it positive because the messages conveyed were delivered to the community.

Authors: Majumder Anish , Chakraborty Nilotpal , Chakrabarti Kisalaya , Ganguly Anindita
Published: January 2022

Fractional Order Differential equations are used for modelling of a wide variety of biological systems but the solution process of such equations are quite complex. In this paper Orthogonal Triangular functions and their operational matrices have been used for finding an approximate solution of Fractional Order Differential Equations. This technique has been found to be more powerful in solving Fractional Order Differential Equations owing to the fact that the differential equations are reduced to systems of algebraic equations which are easy to solve numerically and the percentage error is lower compared to other methods of solutions (like: Laplace Transform Method). Also due to the recursive nature of this method, it can also be concluded that this method is less complex and more efficient in solving varieties of the Fractional Order Differential Equations.

KARİKATÜRİSTLERİN ÇİZGİLERİYLE ŞEKİLLENEN TİYATRO SAHNELERİ
Authors: ÇEVİKAYAK Cem
Published: January 2022

Karikatür sanatı, grafiksel ve çizgisel bir ifade biçimi olarak yüzyıllar boyunca içerik ve görünüm açısından değişim göstermiştir. Bu gelişim sürecinde farklı sanat dallarından etkilenmekle birlikte kendi başına bir anlatım tarzı haline gelerek, pek çok sanat dalını da bu yönde etkilemiştir. Yaratıcısının görsel eğilimine veya dünya görüşüne bağlı olarak şekillenen karikatür örnekleri sadece iki boyutlu yüzeylerde değil, aynı zamanda üç boyutlu formlarda da kendini göstermiştir. Böylece anlatım dili giderek zenginleşen bu iletişim şekli, hacimsel ve devinimsel özellikteki tiyatro sahnesinde de yer bulmuştur.

20. yüzyılda sanat disiplinleri arasında görülen etkileşimler, yeni anlatım biçimlerini doğurmuş ve sanat dalları arasında fikir ve biçim açısından karşılıklı beslenme imkânı sağlamıştır. Klasik üslupların yanında deneysel ve öncü yaklaşımların ön plana çıktığı bu dönemde, modern iletişim araçlarının gelişmeye ve yaygınlaşmaya başlamasıyla pratik ve evrensel bir görsel algıya hitap eden karikatür eserleri, dünyanın çeşitli bölgelerinde farklı tarzlarla biçimlenmiştir. Anlatım dilinin zenginleşmesi ile birlikte sadece basım yayın ürünü olmaktan çıkıp, bir sanat dalı olarak kabul görülen karikatür, Türkiye’de ise 1950 yılından itibaren daha yenilikçi çizgide görülmeye başlamıştır. Cumhuriyet’in ilanı ile birlikte sanat alanında ortaya konan çağdaş görüş ve üsluplar, hem karikatür hem de tiyatro eserlerinde 1950 yılı sonrasında yoğun olarak ortaya çıkmıştır. Bu eğilimlerin etkisiyle sahne tasarımı örneklerinde görülen yenilikler, özellikle komedi oyunlarında karikatür biçimlerinde kendini göstermeye başlamıştır. Araştırma dâhilinde 1950 yılından günümüze Türk Tiyatrosu’nda sahnelenen mizahi oyunlar inceleme altına alınmış ve sahne tasarımında karikatür sanatından etkilerin gözlemlendiği eserler seçilmiştir. Bu süreç içerisinde karikatür sanatının, ele alınan dönemdeki biçimsel değişimi ve seçilen oyun örnekleri üzerinden tiyatro sahnesi görselliğindeki kullanımı irdelenmiştir.

DEVELOPMENT OF FUTURE PRIMARY TEACHERS’ SCIENTIFIC ATTITUDE TOWARDS LIVE OBJECTS: CASE OF OBSERVATION OF A BURGUNDY SNAIL
Authors: Makarskaitė-Petkevičienė Rita
Published: January 2022

The study programme of Primary Education includes Didactics of Natural Science Education (10 ECTS) and Culture and Technologies of Regional Studies (summer practicum) (5 ECTS). The latter study subject aims at educational learning of regional culture, animate and inanimate nature. In natural science education it is particularly important to ensure that curriculum is implemented through active engagement of learners: exploring, experimenting, exchanging experience and discovering. It is important to ensure that learning is conducted employing natural means and school learners are familiarised with real natural objects and phenomena. Therefore, the summer practicum for future primary teachers is organised in green learning environments through exploration and active involvement.
During the summer practicum, which lasts two weeks, students take part in field or hiking trips, complete a big variety of assignments. One of them is familiarisation with the Burgundy snail: its observation and related research assignments. The snail is an appropriate object to learn animate nature as early as pre-school age. Since natural science education is based on the scientific approach, all the research assignments carried out at school contain the structure of a scientific method (observation, hypothesis, experiment, interpretation, conclusions). Growing snails in the classroom, learners are able to get acquainted with the features characteristic of organisms, parts of their bodies; a close access to snails allows for school learners‘ understanding of differences between animate and inanimate objects; a longer care of snails enables school students to observe the process of their reproduction: laying of eggs and development; while feeding snails it is possible to identify what they eat and what food they dislike; observing snails it is not difficult to notice their reactions to the environment and what organs help them to orient in the surrounding environment, etc. Keeping a living creature in the classroom, school children learn to follow hygiene regulations and to responsibly behave with animals. Possessing experience in raising animals, children are able to apply their knowledge and abilities in new contexts, i.e. speaking about feeding, keeping and living conditions of other animals, etc. Following the principle that “personal experience is much more important than the read truth”, school students received a task to keep and observe a Burgundy snail for a week. The students recorded experiments with the snails and reflected their activities in their observation diaries.
The article presents the results received after the analysis of observation diaries of 19 students containing information collected while observing the Burgundy snail. The pedagogical influence of such activities on development of students’ scientific approach is also evaluated in the article.
Keywords: development of scientific attitude, future primary teachers, observation of snails, research works.

Published: January 2022

With the rapid changes in the society and technologies, the attitude towards a child, his education and development at a pre-school education institution is changing as well. The children's brain structure is changed so much that they are able to adopt and perceive visual information faster and easier. While educating children we should take into account the special features of "internet age" children for to better adopt the curriculum to children's needs and learning style. Information technologies help to visualize the ideas and concepts that are difficult to understand, they also help to look with the naked eyes deeper into the invisible world. Therefore, it is important to engage children, teachers and parents with new technologies and their potentials in exploring the living and inanimate nature, to feel the joy of new discoveries.
Systematic and targeted surveillance, explorations, experiments and their analysis provide a better quality to children's education and development. Children are becoming more initiative, creative, their vocabulary fills with new words, their speaking skills are trained better, as well as touch, sight, smell, logical thinking skills, they also learn to count, compare, analyse, to concentrate, to present their research versions, discuss, make conclusions independently and they learn to work in a team.

Calcium sensitive receptor and claudin-14 expression in kidney tissues of two kidney stone models
Authors: Qian Biao , Liu Jihong , Wang Jingshen , Hao Zhiqiang , Wang Qinzhang
Published: January 2022

Introduction

The differences in protein expression of calcium sensitive receptor (CaSR) and claudin-14 in a kidney stone model established by nanobacteria (NB) and ethylene glycol (EG) were compared.

Material and methods

Ninety Wistar male rats were randomly divided into the NB group, the EG group, and the blank control group (NC group), with 30 rats in each group. Three rats of each group were sacrificed every week after injection. Histopathology was used to evaluate the stone formation of each group. The expression of CaSR and claudin-14 protein was detected by immunohistochemistry every week.

Results

There was formation of bright crystals in the kidneys of the EG group and the NB group, but not the NC group. At the 3rd week, the expression of CaSR and claudin-14 in the kidney tissue of the EG group began to increase while that in the NB group increased at the 4th week. The expression of CaSR and claudin-14 protein in the EG group was stronger than that in the NB group. Meanwhile, CaSR was expressed in the NC group but did not change significantly. Claudin-14 was not expressed in the NC group.

Conclusions

Our results indicate that the traditional EG kidney stone modeling method is more rapid than the NB kidney stone modeling method, with a high stone formation rate, and the CaSR and claudin-14 protein expression levels are higher. Meanwhile, the NB used to establish the kidney stone model was isolated from patients with kidney stones, which may imitate the process of natural formation of kidney stones of patients. Therefore, the results of our research are more conducive to related research on the etiology of stones.

Published: January 2022

Introduction

Hyper-CVAD (hyperfractionated cyclophosphamide, vincristine, doxorubicin and dexamethasone) has become a popular regimen for adults with acute lymphoblastic leukemia (ALL). We assessed the efficacy and tolerability of hyper-CVAD in the treatment of adult ALL.

Material and methods

We retrospectively reviewed ALL patients aged 18 or above receiving the hyper-CVAD regimen. We assessed complete remission rate and overall survival, as well as hepatitis B carrier rate and hepatitis flare due to hepatitis B virus (HBV) reactivation.

Results

Fifty-two patients were treated with the hyper-CVAD regimen. The median age at diagnosis was 42 years; 27% of patients were Philadelphia (Ph) chromosome positive. The complete remission (CR) rate was 90.4% after the first cycle of chemotherapy. The induction mortality rate was 1.9%. Three patients required two cycles of hyper-CVAD to achieve CR. The median overall survival was 39.6 months and the 5-year overall survival was 50%. Age over 30 years and white blood cell count of more than 30 × 109/l were found to be prognostic for poor overall survival in multivariate analysis. The hepatitis B carrier rate was 17% in our cohort, and the rate of hepatitis flare due to HBV reactivation was 11% in patients with current infection.

Conclusions

Hyper-CVAD is feasible and tolerable with a good CR rate in the treatment of adult ALL patients. It is an option for the treatment of ALL. Antiviral prophylaxis should be considered in ALL patients with HBV infection to reduce the risk of HBV reactivation.

Introduction

Endothelin-1 (ET-1) gene polymorphisms are implicated in pathogenesis of idiopathic pulmonary arterial hypertension

Material and methods

We studied ET-1 (Lys198Asn and 3A/4A) and endothelin receptor A (ETA) gene (His323His) polymorphisms in 123 subjects with pulmonary hypertension associated with rheumatic mitral valve disease (PH-MVD) and 123 healthy controls.

Results

The mutant homozygous Asn/Asn genotype in Lys198Asn and T/T genotype in His323His polymorphism was more prevalent in PH-MVD group. Presence of Asn/Asn genotype was significantly associated with increased risk (odds ratio 3.9).

Conclusions

ET-1 and ETA gene polymorphisms are prevalent in PH-MVD group suggesting that they may predispose to the development of PH.
SECURETI: Advanced SDLC and Project Management Tool for TI (Philippines)
Authors: Gutierrez Amelie Anne
Published: January 2022

There are essential security considerations in the systems used by semiconductor companies like TI. Along with other semiconductor companies, TI has recognized that IT security is highly crucial during web application developers' system development life cycle (SDLC). The challenges faced by TI web developers were consolidated via questionnaires starting with how risk management and secure coding can be reinforced in SDLC; and how to achieve IT Security, PM and SDLC initiatives by developing a prototype which was evaluated considering the aforementioned goals. This study aimed to practice NIST strategies by integrating risk management checkpoints in the SDLC; enforce secure coding using static code analysis tool by developing a prototype application mapped with IT Security goals, project management and SDLC initiatives and evaluation of the impact of the proposed solution. This paper discussed how SecureTI was able to satisfy IT Security requirements in the SDLC and PM phases.
Warrants Generations using a Language Model and a Multi-Agent System
Authors: Alkhawaldeh Fatima , Yuan Tommy , Kazakov Dimitar
Published: January 2022

Each argument begins with a conclusion, which is followed by one or more premises supporting the conclusion. The warrant is a critical component of Toulmin's argument model; it explains why the premises support the claim. Despite its critical role in establishing the claim's veracity, it is frequently omitted or left implicit, leaving readers to infer. We consider the problem of producing more diverse and high-quality warrants in response to a claim and evidence. To begin, we employ BART [1] as a conditional sequence tosequence language model to guide the output generation process. On the ARCT dataset [2], we fine-tune the BART model. Second, we propose the Multi-Agent Network for Warrant Generation as a model for producing more diverse and high-quality warrants by combining Reinforcement Learning (RL) and Generative Adversarial Networks (GAN) with the mechanism of mutual awareness of agents. In terms of warrant generation, our model generates a greater variety of warrants than other baseline models. The experimental results validate the effectiveness of our proposed hybrid model for generating warrants.

A Educação Histórica enquanto campo de saber pautou-se desde a sua origem pela procura de compreender como se faz sentido do passado e se pensa a História. Assim, a investigação em Educação Histórica tem sido alicerçada em várias abordagens,essencialmente, de foro qualitativo para procurar compreender em profundidade as ideias dos vários agentes educativos e históricos. A Teoria Fundamentada – Grounded Theory tem sido uma das abordagens investigativas partilhadas por vários estudos neste campo de saber, especialmente em Portugal e no Reino Unido. Propõe-se a partilha do percurso investigativo de um estudo em Educação Histórica que pretendia compreender as conceções de professores de História acerca da narrativa enquanto uma das faces da consciência histórica. Assim, esta “autópsia” a este estudo de investigação pode permitir que seja mais percetível como a Teoria Fundamentada pode ser operacionalizada em estudos de investigação em Educação Histórica, desde os momentos iniciais de definição de problema de investigação, participantes, instrumentos de recolha de dados, análise contínua de dados e a construção de teias concetuais, passando pelas decisões que foram sendo tomadas, até à concretização do estudo final e construção de perfis de ideias.A investigação em Educação Histórica tem caminhos a percorrer, considerando-se que estudos de investigação colaborativos e longitudinais poderão ser interessantes para uma compreensão multiperspetivada mais dialógica interculturalmente.

Examining perceptions of academic staff on the factors affecting the use of smartphones as a Constructivist Learning Tool : a proposed model
Authors:   , Dyubele Sithembiso
Published: January 2022

The rapid growth of mobile technology has brought enormous benefits in terms of communication and how some tasks may be accomplished using this technology. However, although many benefits have been identified, many disadvantages have also been identified. The focus of this study was to determine the perceptions of academic staff members on the factors that affect the use of smartphones as a constructivist learning tool by students rather than as a mere communication and distraction gadget. The factors that could affect the use of smartphones as a constructivist learning tool were identified through a comprehensive literature review. Based on the factors found, a model depicting the relevant factors was constructed, and the model was validated. Six independent constructs for the model; Demographics, Attitudes towards smartphones, Facilitating Conditions, Perceived Ease of Use, Perceived Usefulness, and Performance Expectations, were identified by grouping variables to measure each construct together. A questionnaire, based on the constructs and variables, was administered. The resulting data were analysed to validate the model. The conceptual model, tested by the survey, showing the significance of each factor, indicated that all the independent constructs impact the use of smartphones as a constructivist learning tool, either for communication and/or sharing academic-related activities. The results of this study found that Demographics, such as academic departments, Attitudes towards smartphones, Facilitating Conditions, Perceived Ease of Use, Perceived Usefulness, and Performance Expectations all impact the use of smartphones as a constructivist learning tool.
Optimum Values of Tank Volume to Collector Area Ratios of Thermosyphon Solar Water Heaters for Libyan Families
Authors: J. R. Abdunnabi M.
Published: January 2022

Thermosyphon solar water heaters are the best choice to be utilized in residential sector to provide the required hot water in Libya. These systems are autonomy in operation and as a result require less maintenance and hence low operation and initial costs than active system. ln this paper, GenOpt optimization technique provided in TRNSYS simulation program is used for sizing Thermosyphon systems to obtain the optimum size (namely V/A ratio) of Thermosyphon system that suits Libyan families according to the weather and operating conditions of Tripoli. The typical hot water load pattern and quantity of the Libyan families are taken from a field study conducted on a number of the solar systems for a whole year. Whereas, the typical weather data are taken from five-year measurements recorded at CSERS weather station.
The results showed that the optimum storage tank volume to collector area ratio of Thermosyphon systems is between 49-60 Lit/m2 for the most common collector characteristics ratio (equation!!) and the auxiliary heater set point temperature ranges from (45-60C).

Published: January 2022

Two identical single - effect of single basin solar stills were designed, fabricated, tested and evaluated. One was operated alone while the other was coupled to a flat plate solar collector. Both were installed at some site in Tripoli, Libya at 32" 48' 51' N and 13’’26' I7' E. They were south oriented with a tilt angle of 23“. Measurements of various parameters were taken in August 2009 at each hour for several days under different operating conditions. Two operational modes were considered. The tests were conducted using seawater of 35,000 ppm. The depth of water in the basin was kept fixed at 60 mm. Fresh water production of the coupled still was measured to be 6.6 L/day which is higher than that of the single still by 55.84%. The maximum daily efficiency was calculated to be 14.48% for the single still while it was only 24.18% for the coupled still. The still thermal performance was found to have a complex function of geometry, construction, operational conditions, site characteristics and layout details.

This experimental study deals with a single-basin solar still using various absorbing materials with and without black painting. Different types of absorbing materials with and without black painting were used to enhance the solar still productivity throughimprovement in absorptivity. Those materials are steel and aluminum with and without black painting and rubber. Two identical solar stills were manufactured using locally available materials. All the results were compared together to reach the best absorbing materials with and without painting that can be used for solar still. It was found that the rubber absorber has the highest water collection during the daytime, followed by the black painted steel absorber, then by black-painted aluminum absorber and steel without painting absorber. The average enhancement in the daily productivity was about 50% for the rubber absorber comparedwith the black painted aluminum absorber and about 43% for the rubber absorber compared with the black painted steel absorber.
