Applying the Strategizing Methodology at the Regional Level: Opportunities and Advantages
Authors: Gerelishin R. I.
Published: May 2023

The article provides arguments in favor of the greatest efficiency and significance, both from a scientific and practical point of view, using the strategizing methodology of a foreign member of the RAS, doctor of economics, professor V.L. Kvint. The use of this methodology acquires particular importance and relevance at the present stage of economic development, which can be described as an «extraordinary period». It is shown that the use of this methodology at the regional level in the absence of consensus not only in terms of the key determinants of development, but also in the very definition of «region», determined by the goals and objectives of a particular study, allows aggregating heterogeneous factors of economic and social development, generalizing the ideas of various economic schools, and analyze them through the prism of opportunities and threats for more effective formation of strategic priorities, taking into account the determining factor of time.

A pesquisa situa-se no campo de investigação da Educação Histórica e abarca as discussões sobre o novo humanismo de Jörn Rüsen (2021) através do trabalho com a história difícil (burdening history), conceito desenvolvido por Bodo von Borries (2011). O foco deste presente texto é ponderar sobre a aprendizagem da história difícil do Holocausto em aulas de História e sobre o novo humanismo de Jörn Rüsen, entendendo que o Holocausto trouxe questões e paradigmas que vão além de seu tempo e que trouxeram consequências para a forma como se entendem os direitos humanos e a dignidade humana nos dias de hoje.
Compassos entre o ensino de História e a formação de professores: trajetórias em construção.
Authors: Dias Sueli de Fátima , Cainelli Marlene Rosa
Published: May 2023

Este artigo integra estudos que analisam como professores em serviço acompanham discussões acerca do ensino de História e concepções teórico-metodológicas da Educação Histórica. Aborda elementos que relacionam o ensino de História e a formação de professores a partir do estabelecimento da disciplina na grade curricular das escolas do Brasil. Reforça, apoiando-se em concepções como a de Fenelon (1982) e a de Nadai (1993), que as primeiras relações entre formação de professores e ensino de História são heranças de estruturas educacionais europeias, de fins do século XIX e século XX, embasadas em ideias positivistas, cientificistas e tecnicistas. Desenvolve-se, seguindo a periodização de Schmidt (2012), para o ensino de História no currículo escolar brasileiro, estabelecendo quatro fases que possibilitam analisar aspectos das questões educacionais e a conjuntura sociopolítica do país: 1. Construção do código disciplinar da História no Brasil (1838-1931); 2. Consolidação do código disciplinar da História no Brasil (1931-1971); 3. Crise do Código disciplinar da História no Brasil (1971-1984); 4. Reconstrução do código disciplinar da História no Brasil (1984-?). Destaca princípios da organização do ensino de História e consequentes exigências para a formação de professores envolvidas com a transmissão de informações que não priorizam a análise, reflexão ou interpretações de diferentes perspectivas dos eventos históricos. Contribui no questionamento das perspectivas do processo de ensinar e aprender História e sobre para qual tipo de sociedade contribuir.

Investigating Routing Protocol Attack for Low Power and Lossy IoT Networks
Authors: Kiran Usha , Maurya Poonam , Sharma Himanshu
Published: May 2023

Internet-of-Things (IoT) networks are characterized by low-powered nodes
with limited computational power and storage capacity. Consequently,
protocols dedicated to Low Power and Lossy networks (LLNs) are designed
to support communication in such resource-constrained nodes. One such
protocol is Routing Protocol for Low-Power and lossy networks (RPL)
which builds and maintains routes in RPL-based networks, leading to
optimized routing and lower network overhead. However, the RPL-based
protocol has several internal and external vulnerabilities that must be
explored and addressed. Therefore, the present study illustrates the
impact of several RPL-based attacks, including DIS attack, version
number attack, decreased rank attack, and WPS attack, by employing the
Contiki Cooja network simulator with specific simulation scenarios. In
addition, we conduct a comparative analysis of the RPL-based attacks and
find that the WPS attack results in the highest packet loss rate of
26%, whereas the DIS attack, version number attack, and rank attack
result in packet loss rates of 17%, 15%, and 13%, respectively.
Characterization of dopaminergic projections from the ventral tegmental area and the dorsal raphe nucleus to the orbital frontal cortex.
Authors: Noble Duncan , Mohammadkhani Aida , Qiao Min , Borgland Stephanie
Published: May 2023

The orbitofrontal cortex (OFC) is a key node in the
cortico-limbic-striatal circuitry that influences decision-making guided
by the relative value of outcomes. Midbrain dopamine from either the
ventral tegmental area (VTA) or the dorsal raphe nucleus (DRN) has the
potential to modulate OFC neurons, however it is unknown at what
concentrations these terminals release dopamine. Male and female adult
DATIRES-CRE-tdTomato mice were injected with AAV2/8-EF1a-DIO-eYFP into
either the DRN or VTA or the retrograde label CTB 488 in the medial or
lateral OFC. We quantified co-expression of CTB 488 or eYFP with
tdTomato fluorescence in VTA or DRN as well as eYFP fiber density in the
medial or lateral OFC. Both VTA and DRN dopamine neurons project to
either the medial or lateral OFC, with greater expression of fibers in
the medial OFC. Using fast-scan cyclic voltammetry, we detected
optogenetically evoked dopamine from channelrhodopsin2 (ChR2)-expressing
VTA or DRN dopamine terminals in either the medial or lateral OFC.
Consistent with increased fiber expression in the medial OFC, dopamine
was more reliably detected in this region from optical stimulation of
VTA or DRN dopamine terminals. We assessed if optical stimulation of
dopamine from the VTA or DRN onto the medial OFC could alter layer V
pyramidal neuronal firing; however, we did not observe a change in
firing at stimulation parameters which evoked dopamine release from
either projection. In summary, dopaminergic neurons from the VTA or DRN
project to the OFC and release submicromolar dopamine in the medial and
lateral OFC.
Simulating and Conducting a Comparative Analysis of Thermal Management in Refrigerators Using Phase Change Materials during Power Outages
Authors: M Chandrashekara , Barnwal Rohon , Mehla Neeraj , Saini Dinesh Kumar
Published: May 2023

In this study, the benefit of phase change materials (PCMs) in
maintaining the temperature range of a refrigerator during a power
outage was investigated. It aims to analyze temperature fluctuations
during power cuts in domestic refrigerators with a multi-PCM system and
compare the results with that of a model without PCM. The PCM was clad
in different refrigerator sections, and the system was simulated and
analyzed for temperature range in different sections. Ethylene glycol,
eutectic mixture, and n-tetradecane were clad in freezers and
mid-compartments. It was observed that the temperature was maintained
within the operating range after different time steps. It was seen that
the temperature saturated to 299K throughout the refrigerator in 600
seconds. However, with the PCM, the temperature in the evaporator was
268.75K; in the mid compartment, it was 279.56K; in the chiller, it was
289K after 200 seconds. Similarly, after 600 seconds, the temperature
was 268.5K in the evaporator, 280K in the mid compartment, and 290K in
the chiller. Therefore, it is evident that PCMs are effective for
maintaining the refrigerator’s temperature range during power cuts.
Unlocking the Power of Mitochondrial Function: Real-time Assessment of Mitochondrial ATP contents and Response Against Inhibiting and Stimulating Substrates (MitoRAISE)
Authors: Chang Eun Sol , Song Kyoung , Song Ji-Young , Sung Minjung , Lee Mi-Sook , Oh Jung Han , Park Yeon Hee , Kim Ji-Yeon , Jung Kyungsoo , Choi Yoon-La
Published: May 2023

Purpose The objective is to develop a real-time Mitochondrial ATP
contents and Response Against Inhibiting and Stimulating Substrates
(MitoRAISE) assay and assess its potential to evaluate the mitochondrial
oxidative phosphorylation function. Methods MitoRAISE measures the total
ATP contents, ATP synthesis capacity, and the response to inhibitory
substrates. The measurements were all quantified with an ATP standard
curve and validated with in vitro testing. MitoRAISE was then applied
using peripheral blood mononuclear cells (PBMCs) from 35 healthy
volunteers and 20 breast cancer patients. Result Results from isolated
mitochondria, cells with different permeabilization percentages, and
cells with damaged mitochondria demonstrated the ability of capturing
ATP signals specifically from the mitochondria. Breast cancer PBMCs
exhibited a significant increase in glutamic acid- and malic
acid-induced mitochondrial ATP synthesis capacity yet a significant
decrease in mitochondrial DNA copy number (mtDNA CN) compared to healthy
PBMCs. Furthermore, breast cancer PBMCs mostly showed negative
correlation between mtDNA CN and parameters from MitoRAISE but healthy
individuals showed positive correlation. Conclusion We developed a quick
and easy method to detect real-time mitochondrial activity in live
cells. Monitoring mitochondrial ATP synthesis capacity and sensitivity
to inhibitory substrates could aid in assessing the functional status of
mitochondrial oxidative phosphorylation.

Effects of cutting stage and bacterial inoculant on quality of the red clover silage
Authors: Djordjevic Snezana , Mandic Violeta , Djordjevic Nikola
Published: May 2023

In this paper, the influence of cut at two maturity stages (the beginning of
the flowering stage and mid bloom stage and bacterial inoculant ?Silko za
lucerku? (contains Lactobacillus plantarum and Pediococcus spp.) on the
quality of red clover silage were presented. The commercial cultivar Nada
selected at the Bc Institute in Zagreb was used for investigation. The
silage was examined in mini-silos (glass jars of 1.5 l volume with plastic
fermentation valve) in the laboratory. The chemical composition, energy and
fermentation characteristics of silages were analyzed 90 days after
ensiling. The values of dry matter, acid (ADF) and neutral detergent fibre
(NDF), lactic acid and pH were significantly lower, while the crude protein
content, total digestible nutrients (TDN), relative feed value (RFV),
ammonia nitrogen in total nitrogen (NH3-N/TN), acetic and butyric acids were
significantly higher in the first cutting stage. The inoculation with
inoculant ?Silko za lucerku? improved the chemical, energy and fermentation
parameters of silages. Inoculant-treated silage had lower contents of ADF,
NDF, NH3-N/TN, acetic and butyric acids and pH, and higher contents of dry
matter, crude protein, TDN, RFV and lactic acid than control. Accordingly,
timely cutting stage and application of microbial inoculant can contribute
to a lesser loss of nutritional value of the forage and promote silage
quality.

inequality problems are developed, and error bounds are obtained in terms of
the residual gap function, the regularized gap function, and the D-gap
function. With the help of these constraints, one can effectively estimate
the distances between any feasible point and the solution set of problems
involving generalized multivalued vector inverse quasi-variational
inequality.
Minimax inequalities for functions with noncompact domain and diagonal GC-quasiconcavity and their applications
Authors: Lu Haishu , Pan Chengqing
Published: May 2023

This paper introduces the notion of diagonal GC-quasiconcavity which
generalizes the notions of quasiconcavity, CF-quasiconcavity, diagonal
transfer quasiconcavity, C-quasiconcavity, diagonal C-concavity, and
diagonal C-quasiconcavity. We first establish some theorems for the
existence of ?-equilibrium of minimax inequalities for functions with
noncompact domain and diagonal GC-quasiconcavity in topological spaces
without linear structure. Next, we apply these results to characterize the
existence of saddle points and solutions to the complementarity problem.
Finally, we derive some intersection theorems and their equivalent forms.
Use of aliphatic thiols for on-site derivatization and gas chromatographic identification of Adamsite
Authors: Rozsypal Tomas
Published: May 2023

The report describes the development of methods for rapid and simple identification of Adamsite in mobile laboratory conditions using a field gas chromatograph coupled with mass spectrometer. Adamsite is a chemical warfare agent with unique properties that cannot be analysed without conversion to a volatile derivative. Derivatization procedures with 5 aliphatic thiols (ethanethiol, 1-propanethiol, 2-propanethiol, 1-butanethiol and 1-hexanethiol) were developed and compared. The retention characteristics of the derivatization products, peak characteristics and the formation of unwanted artifacts in the chromatograms were monitored. The influence of the reaction media and the time dependence of the reaction were also objects of interest. Other investigated parameters were the optimal reaction temperature and the volume of the derivatization agent. Mass spectra of newly created substances that are not yet included in the chemical weapons related databases were recorded. With optimal reagents (1-butanethiol and 1-hexanethiol), the calibration procedures for analyte determination were subsequently developed, and the methods were verified during the Adamsite identification test in selected environmental and urban matrices.

Authors: Abubakar Attahir , Mahamat Addi , Bala Ahmed
Published: May 2023

Considering the potential role of education in enhancing the socioeconomic prosperity of countries, this study examines the effect of education on economic growth and household welfare in Asian countries. Static and dynamic panel data estimation techniques were employed for analysis. The findings of the study reveal a significant positive effect of education on economic growth and household welfare, with the growth effect of male education being marginally higher than female education. Interestingly, the household welfare effect of female education is revealed to be higher than male education. These findings imply that for economic growth and household welfare enhancement in the region, female education is as important as male education. Consequent to these findings, the study emphasises the need for policy measures aimed at enhancing both access and quality of education for people of all genders in the region.

Image analysis is a very well method for characterization of different
materials structures, as well as changes and occurred defects in structure
caused by different influences. In this paper, possible application of image
analysis will be presented related to the monitoring thermal shock behavior
of selected refractory materials. Different parameters such are R parameter,

Authors: Kokunesoski Maja , Janackovic Djordje , Kicevic Dusan , Ilic Svetlana , Saponjic Aleksandra
Published: May 2023

Effect of methyl methacrylate (MMA) as a binder and heating treatment were
investigated to improve green alumina compacts machinability. Properties of
green compacts and their corresponding sintered samples prepared with and
without MMA were compared. Investigation of green and sintered properties
was performed on samples compacted at applied pressures up to 150 MPa. After
pressing, samples with MMA were thermally treated at 115oC. The intention
was to enhance the polymerization of MMA at a temperature a little higher
than the glass transition temperature (Tg = 103oC) of poly (methyl
methacrylate). Green compacts with MMA had higher green density values than
those without MMA. Sintered samples with MMA had lower values of sintered
density and higher values of total porosity; after sintering, relative
linear shrinkage was around 15 % for the whole range of applied pressures.
The possibility of easily machining the green compacts with MMA produces
great possibilities for application in many fields
Peirce on perception and abduction
Authors: Andjelkovic Miroslava
Published: May 2023

Abduction is commonly understood as a reasoning of the form: q; if p, then q therefore p. In the paper I argue that this is not only a simplification but also a distortion of Peirce's conception of abduction, since it ignores that abduction is, as Peirce explicitly claims, an induction over properties. Further, the epistemological significance of Peirce's concept of abduction is neglected as well, since abductive reasoning is almost exclusively related to the way in which one forms a scientific hypothesis, while it is overlooked that even the most elementary forms of knowledge involve abduction. Namely Peirce claims that the perceptual judgment is the limiting case of the abductive judgment, and this thesis cannot be understood properly if abduction is understood as having the above mentioned form.

Metric on the space of systems behavior functions represented by fuzzy measures
Authors: Bocharnikov Victor , Sveshnikov Sergey
Published: May 2023

G. Klir proposed to describe the behavior of complex systems using behavior functions (BFs) - invariant constraints on the set of system states. BFs are one of the most productive tools for studying the functioning of systems. To study systems, it is necessary to have a metric for measuring of the difference between two BFs. To describe BFs modern researchers do not use distributions other than probability or possibility. But these distributions can be considered as special cases of Sugeno fuzzy measures, the use of which greatly expands the possibilities in the study of systems. However, metrics to measure the difference between fuzzy measures have not been developed. Therefore, in this article, the authors proposed a new metric and an algorithm for its calculation for the case when BFs are described by Sugeno fuzzy measures. This metric is based on the Cartesian product of fuzzy measures and the use of our proposed concentration function. The metric makes it possible to compare the behavior of systems in the case of describing BFs by Sugeno fuzzy measures with different modalities, as well as to ensure the priority of taking into account the set of the most significant states of the system.
Root rot diseases of sugar beet
Authors: Jacobsen Barry
Published: May 2023

Root rot diseases of sugar beet caused by Rhizoctonia solani (AG 2-2 IIIB and AG 2-2 IV), R. crocorum, Aphanomyces cochlioides, Phoma betae, Macrophomina phaeseolina, Fusarium oxysporum f.sp. radicis-betae, Pythium aphanidermatum Phytophthora drechsleri, Rhizopus stolonifer, R. arrhizus and Sclerotium rolfsii cause significant losses wherever sugar beets are grown. However, not all these soil-borne pathogens have been reported in all sugar beet production areas. Losses include reduced harvestable tonnage and reduced white sugar recovery. Many of these pathogens also cause post harvest losses in storage piles. Control for diseases caused by these pathogens include disease resistant cultivars, avoidance of stresses, cultural practices such as water management and the use of fungicides.
Potential and real residues of pesticides in sugar beet
Authors: Sovljanski Radmila , Lazic Sanja , Vukovic Slavica
Published: May 2023

Crops and their products can be contaminated either by direct application of pesticides for the protection of insects, acarives, agents of plant diseases and/or weeds, i.e. as the result of growing them on the soil containing pesticide residues applied in previous years. For the protection of sugar beet in our country, 23 insectisides, 17 fungicides and 18 herbicides have been registered. The pre-harvest interval (PHI) ranges from 14 to 42 days i.e. they are provided by the time of application (PTA) whereas the pre-harvest interval for herbicides ranges from 30 to 91 days and is ensured by the application period. Based on the results from the literature and on their own studies, the authors are of the opinion that the residues of the applied pesticides in sugar beet protection in accordance with the principles of good agricultural practice will be significantly lower than the maximum tolerable ammounts and that at the level from 1/4 to 1/10 of MRL. IT is necessary to emphasize the necessity of MRL determination both in leaves and in sugar loaf.in case they are used as animal feed.
State of weed infestation and features of sugar beet protection in Belarus
Authors: Soroka Sergey Vladimirovich , Gadzhieva Galina
Published: May 2023

The changes of phytosanitary situation recently taking place in sugar beet crops in the Republic of Belarus are shown. It is noticed that in the crop agrocoenosises there is a high infestation level caused by Japanese barnyard millet (Echinochloa crus-galli (L) Pal. Beauv), field sowthistle (Sonchus arvensis L), chickweed (Stellaria media (L) Vill), quick grass (Agropyron repens (L) Pal Beauv), matricary (Matricaria perforate Merat), creeping thistle (Circium arvense (L) scop), marsh woundwort (Stachus palustris L) wild buckwheat (Polygonum convolvulus L), bristle stem hemp nettle (Galeopsis tetrahit L), common horsetail (Equisetum arvense L), field forget-me-not (Myosotis arvensis (L) Hill), shepherd's purse (Capsella bursa-pastoris (L) Med) etc. Due to non-observance of preventive and separate agrotechnical techniques especially in spring-summer period, such weeds as bedstraw (Galium aparine L), white campion (Melandrium album (Mill) Garcke), green amaranthus (Amaranthus retroflexus L) started to appear in the crops. To protect sugar beet effectively, two variants of herbicides application are proposed. The first one - a combined, one stipulating soil action herbicides application before planting or before sugar beet seedlings emergence and on seedlings - to carry out two treatment by post-emergence preparations. The second variant, a split post- -emergence herbicide application (two-three times spraying) on growing weeds at small application rates. In the next 5-6 years, a combined method will be of a primary importance in the conditions of the Republic.
Forecasting of major sugarbeet pest occurrence in Serbia during the period 1961-2004
Authors: Camprag Dusan , Sekulic Radosav , Keresi Tatjana
Published: May 2023

In Serbia, sugar beet is grown in the province of Vojvodina mostly. The increase in areas sown to this crop in the province from 30,000 hectares in 1931-1939 to over 70,000 in 1951-2000 provided a large boost to the reproduction of sugar beet pests in this part of the country. More than 15 species are considered major pests of sugar beet. The Department of Plant and Environmental Protection of the Faculty of Agriculture in Novi Sad and the Institute of Field and Vegetable Crops in Novi Sad have been making forecasts of the occurrence of major sugar beet pests since 1961. Over the last 30 years (1975-2004), the following average pest numbers per meter square at the end of the growing season have been recorded: Bothynoderes punctiventris (3.3), Elateridae (3.6), Melolonthidae (1.0), Scotia spp. (0.4), Mamestra spp. (1.5) and Scrobipalpa ocellatella (14.8). In addition to these population dynamics of the following pest species are also monitored: Lixus scabricollis, Chaetocnema tibialis, Cassida spp., Aphis fabae, Pemphigus fuscicornis, Autographa gamma and Loxostege sticticalis.

Published: May 2023

In the period 2001-2004, experiments were conducted in the region of Backa (northern Serbia) to assess the efficiency of insecticide treatment of sugar beet seeds in controlling soil pests (larvae of Elateridae family) and reducing the damage caused by beet weevil (Bothynoderes punctiventris G e r m) and flea beetle (Chaetocnema tibialis I l l i g). Several insecticides mostly systemic ones (carbofuran, thiamethoxam, fipronil, imidacloprid and clothianidin), and their combinations with pyrethroids in different doses were tested in field conditions. Stand density, percentages of plants damaged by B. punctiventris and C. tibialis, injury level and weight of juvenile plants served as parameters for evaluation of insecticide efficiency. Most of the insecticides applied to seeds provided a significantly better stand density compared with the untreated control. Because of their systemic action, imidacloprid, thiamethoxam and their mixtures with pyrethroids provided very good protection of juvenile plants from C. tibialis and in some cases from B. punctiventris.
The phytosanitary form and fighting measures diseases and pests of sugar beet from Republic of Moldova
Authors: Timus Asea , Croitoru Nichita
Published: May 2023

Sugar beet is one of the most important agricultural crops in the Republic of Moldova. The North and Central regions have good enough pedoclimatic conditions. The genetic potential of sorts and hybrids can be created through the application of modern technologies in order to grow at least 32-35 tons/ha of sugar beet roots. In the Republic of Moldova, sugar beet vegetates between 160 and 180 days in the first year and needs approximately an amount of 2400-2900?C, average of 15.3-15.4?C. Each phenological phase needs different temperatures: at least 4C? is necessary for planting and springing an amount of 650?C is necessary for foliar apparatus; an amount of 1150- 1800?C is necessary to grow the volume of roots and for sugar depositing the average of 2400 to 2600?C is necessary. The mentioned temperatures ensure a normal development of sugar beet plants. If these temperatures fluctuate, the pathogens and pests are stimulated to develop. The most frequent diseases of sugar beet are: Pythium de baryanum Hesse., Aphanomyces cochlioides Dresch. Peronospora schachtii Fuck., Phoma betae Fr. Cercospora beticola Sacc. Erysiphe communis Grev. f. betae Jacz., virosis - Beta virus 2, 3 si 4 etc. The main pests belong to the following categories: Homoptera: Aphis fabae Scop. (fam. Aphididae), Pemphigus fuscicornis Koch. (fam. Pemphigidae) Coleoptera: Agriotes sp. (fam. Elateridae), Chaetocnema concinna M. Ch. breviuscula Fld., Cassida nebulosa L. (fam. Chrysomelidae), Atomaria linearis Step. (fam. Cryptophagidae); Bothynoderes punctiventris Germ., Tanymechus dilaticollis Gyll., T. palliatus F., Psalidium maxillosum F.

Several small studies have indicated that daily emollient use from birth might delay, suppress or prevent atopic dermatitis (AD). Two larger trials did not confirm this; however, a recent smaller study indicated a protective effect if daily emollient use is used in the first 2 months of life. Further research is needed to evaluate the effect of emollient use on development of AD. The current study randomly assigned 50 newborns who were at high risk of developing AD (1:1) to receive general infant skin-care advice (control group), or skin-care advice plus emollient with advice to apply emollient at least once daily until 1 year of age (intervention group). Repeated skin examinations, skin physiology measurements and skin microbiome profiling were performed. Of the children in the intervention and control groups, 28% and 24%, respectively, developed AD (adjusted Relative Risk (RR) 1.19, p = 0.65, adjusted risk difference 0.05). Skin pH decreased and transepidermal water loss and stratum corneum hydration increased over time in both groups with no significant differences. In the intervention group skin microbiome alpha diversity increased earlier, and the abundance of Streptococcus and Staphylococcus species were significantly reduced at month 1. Daily early emollient use in children with high risk of AD was safe, but it did not significantly reduce the risk of developing AD or impact skin physiology development.

Published: May 2023

Podcast is a platform for people to talk about something off-air which can be found on YouTube. This study aims to identify the type of code-mixing and to explain the reasons of using code-mixing in the Podcast. This qualitative research collected the data from the speakers’ utterances in the YouTube video entitled “AZKA CORBUZIER LOH UDAH PACARAN SKRG!” using non-participant observation and documentation. The result revealed that there are 172 data containing code-mixing. Firstly, in Muysken’s typology of code-mixing theory, there are: 99 data of alternation type, 72 data of insertion, and one data of congruent lexicalisation. Secondly, the reasons of code-mixing involved two theories: Hoffman’s theory and Bhatia and Ritchie’s theory. In Hoffman’s theory, there are 124 data as talking about a particular topic, 19 data as emphasising the intention, 11 data as clarifying by using repetition, six data as uncategorised, five data as being emphatic about something, three data as quoting somebody else, and two data as expressing interjection and as expressing group identity. In Bathia and Ritchie’s theory: (1) participants: father and son relation; (2) situational factors: podcast setting, involving private domain, intimate and informal conversation, and social variables: 14 years old and 44 years old and wealthy family; (3) message-intrinsic consideration: quotation, reiteration, message-qualification, topic-comment/relative clause, hedging, and interjection/sentence filler; (4) language attitude, dominance, and security: both speakers have positive attitude toward each other’s code-mixing, balanced language dominant, and respectable while exchanging code-mixing.Keywords: code-mixing, sociolinguistics, non-participant obsevation, podcast, bilingualism
The environmental impact of renewable energy
Authors:   Bucks New University, UK, Ivanova Neli , Datta Palto ,   Regent College London, UK
Published: May 2023

Purpose: The purpose of this study is to ascertain the environmental impact of renewable energy sources. Methodology: The research combines a pragmatist epistemology and an exploratory, inductive technique. Using the United Kingdom as a case study, the study collects primary data on participants' perspectives, perceptions, and attitudes regarding the connection between renewable energy sources and the environment through a self-administered survey (with 400 subjects) and in-depth interviews (sample size 25). Findings: Participants expressed worry about climate change and a keen understanding of the favourable effects of renewable energy sources on the environment, particularly in terms of pollution reduction, global warming reduction, and climate change mitigation. Practical Implications - The primary rationale for increased calls for the transition away from non-renewable energy sources is the desire to mitigate their negative environmental implications. Renewable energy sources must be expanded to meet this goal. Additional study is needed to identify viable policy pathways for accelerating the transition to renewable energy. Originality: To the best of the researcher's knowledge, this is the first study combining self-administered survey with 400 subjects and in-depth interviews with 25 subjects in the United Kingdom on the public's perspective of renewable energy, its status of development, hurdles, and role in mitigating global warming and climate change.
