Authors: Yadav Rajeshwer Prasad
Published: May 2024

The availability of digital resources has increased dramatically in school setting. The main objective of the study is to find out the use of digital resources in the science classrooms and its pedagogical impact on school-level science teaching and learning. The study followed descriptive design. For the study, 12 secondary (community-6, institutional-6) among 17 secondary schools that run Class 11 and 12 in science stream were randomly selected. All science teacher including lab instructors were the participants of the study. Observation forms and questionnaires were used as research tool. Percentage and Spearman’s correlation test were performed by using SPSS version 20. The results showed that digital resources were generally available in the classrooms but were not widely used. Furthermore, the science teachers who had excellent knowledge regarding digital resources and abilities had better performance than those with less knowledge and skill regarding digital resources as they work less aware of pedagogical implications of digital resources.  Science teaching impacts were found to be significantly influenced by teachers’ age, experience, information communication and technology certifications, and teaching strategies. In the end, it was discovered that competencies of digital resources directly improved science teaching and learning results, enabling a paradigm shift away from conventional teaching techniques.

Authors: Egwuatu Tochukwu Frank , Iroanya Onyekachi Ogbonnaya
Published: May 2024

The aim of the study was to evaluate the prevalence of psychoactive substance abuse and association of single nucleotide polymorphisms in Cannabinoid-Receptor 1 (CNR1) gene with chronic polysubstance use among the Nigerian male commercial vehicle drivers selected from the three major ethnic groups in Nigeria. A-10-Panel Generic Multi Drug Urine Dip Card Test Kit was used in the study and four SNPs (rs2023239, rs806378, rs806379 and rs806381)in CNR1 were genotyped in 60 subjects (20 drivers from each ethnic group) by using Sequenom MassARRAY Genotyping System. The four target SNPs revealed the following genotypes namely rs2023239: CC (20%), CT (40%), TT (40%); rs806378: CC (100%); rs806379: AA (20%), AT (50%), TT (30%); rs806381: AA (50%), GA (50%) in cases among the Hausa drivers. However, among the Igbo drivers, the four target SNPs showed the following genotypes namely rs2023239: CC (20%), CT (40%), TT (40%); rs806378: CC (80%) CT (20%); rs806379: AA (10%), AT (50%), TT (40%) and rs806381: AA (30%), GA (70%) in cases. Additionally, the target SNPs also revealed the following genotypes namely rs2023239: CC (30%), CT (30%), TT (40%); rs806378: CC (90%), CT (10%); rs806379: AA (10%), AT (60%), TT (30%) and rs806381: AA (70%), GA (20%), GG (10%) in cases among the Yoruba drivers. The SNPs rs2023239, rs806378 and rs806381 were significantly linked with polysubstance and chronic cannabis use in the sample population (Hausa, Igbo and Yoruba) (p˂0.05). The SNP rs806379 associated significantly with polysubstance and chronic cannabis use in the Igbo drivers only (p˂0.05). Conclusively, this study provides probably the first data on the association of CNR1genetic polymorphism with chronic polysubstance use among Nigerian male commercial motor vehicle drivers.

Finalmente, se recoge otros dos últimos capítulos, uno sobre preguntas de evaluación y el otro sobre problemas cuantitativos cuya finalidad es que sirvan de repaso y de reto para comprobar la comprensión de aspectos fundamentales que se abordan en los capítulos anteriores.
How Did People Tweet in the 2018 Malaysian General Election: Analysis of Top Tweets in #PRU14
Authors: Kasmani Mohd Faizal
Published: May 2024

Since 2008, Malaysian General Elections were often dubbed as “social media election”. Twitter's combination of brevity, immediacy, interactivity and virility has enabled it to become a go-to platform for political communication among politicians, journalists and citizens. To understand Twitter uptake among Malaysian citizen during the 2018 general election, this article adopts Shoemaker and Reese’s hierarchy-of-influences model. The top 50 tweets from the political hashtag #pru14 between 28 April 2018 until 10 May 2018 will be analysed. The analysis will be based on two types of influences that may affect this mediation process; influences of political reality, the influences based on individual characteristics of users and the nature of communication on Twitter. This study found that when the mediated political event cannot be accessed directly by the public, tweets from influencers dominates the Top Tweets. However, when the public can get access to the mediated events directly, tweets from the public are catching the attention on the #PRU14. This study also found that there are more male twitters than female, and most of them appeared to be in their youth.

O objetivo do estudo foi identificar por meio de Machine Learning regras para a modulação das previsões de afeto (FS) e percepção subjetiva de esforço (PSE) em relação ao exercício, analisando o grau de importância de diferentes fatores biológicos. Cada participante (n = 34 [52.9% sexo feminino], Idade = 25.4 ± 6) foi submetido a um teste em que precisou prever o quanto sentiria de FS e PSE em relação à um Sprint de 107 metros que estava prestes a realizar. As respectivas respostas foram analisadas através do algorítmo de árvore decisional para estabelecer regras para a modulação da FS e PSE com base nas seguintes características de cada sujeito: percentual de gordura (%G); massa magra (%MM); relação cintura e quadril (RCQ); nível de atividade física autodeclarado (NAF-AUTO); frequência cardíaca em repouso (FCr); sexo e idade. Como resultado, sujeitos insuficientemente ativos previram menor valor de FS (1.5 [1-3]) em comparação com os muito ativos (5 [3-5]) (p < 0.05). As principais regras para os participantes reportarem os mais baixos valores de FS foram ter as seguintes características: %MM ? 48.9, FCr > 73. Os mais altos valores de FS apresentavam %MM > 48.9. Os mais altos valores de PSE apresentavam %G > 16.4, enquanto os mais baixos apresentavam %G ? 16.4. Conclui-se que as regras para o perfil que previu o maior desprazer foi apresentar composição corporal e capacidade cardíaca menos saudáveis, o que previu maior prazer apresentava características opostas. Além disso, um menor nível de atividade física também pode influenciar uma previsão menos prazerosa do exercício. No caso da PSE, existem dois perfis iniciais divididos pelo %G, sendo que o com menor valor previu menor esforço e o perfil com maior %G apresentou maior heterogeneidade nas características.

Published: May 2024

Durante o exercício físico o sistema músculoesquelético tem um papel fundamental na orquestração metabólica de outros órgãos. O equilíbrio entre as ações pró e anti-inflamatórias das diversas citocinas auxilia para a recuperação completa do tecido pós exercício. Foi realizada uma revisão sistemática da literatura com o objetivo de avaliar os efeitos do exercício físico sobre as citocinas inflamatórias em praticantes de atividade física. Cinco bases de dados foram pesquisadas para o levantamento dos artigos: PubMed, EMBASE, LILACS, MEDLINE e Web of Science. Foram incluídos apenas ensaios clínicos randomizados controlados que apresentaram a relação entre marcadores inflamatórios (citocinas) e o treino de exercício físico. As amostras variaram de 7 a 25 atletas ou praticantes de alguma modalidade de atividade física saudáveis submetidos a protocolos de treino físico. Fizeram parte deste estudo 11 artigos, realizados em vários países, envolvendo diversas modalidades esportivas. Apesar do número reduzido das amostras em todos os estudos analisados, foi possível destacar que o exercício físico promove aumento imediato nos níveis séricos de citocinas pró-inflamatórias com destaque para a IL-6 e TNF-?, entretanto alguns mediadores anti-inflamatórios diminuem após a recuperação, principalmente a IL-10. Além disso a intensidade do exercício físico pode alterar o estado inflamatório.

Cerca de 79 a 83% das crianças com Transtorno do Espectro Autista (TEA) não apresentam desempenho nas habilidades motoras dentro do esperado para sua faixa etária e, ainda, os aspectos motores não compõem os critérios diagnósticos para o TEA. Por esse motivo, o objetivo do artigo é realizar um levantamento e análise da literatura acerca dos instrumentos de avaliação motora em crianças com TEA. Se trata de uma revisão de literatura, cujas buscas por estudos foram feitas nas bases de dados Medline, PubMed e SciELO, utilizando os descritores evaluation motor; autism spectrum disorder; evaluation; autism disorder e motor skills. Foram incluídos artigos com texto completo disponível nos idiomas português, inglês e espanhol, publicados nos últimos 10 anos, que avaliassem crianças e adolescentes de 0 a 18 anos diagnosticadas com TEA e que utilizassem algum instrumento de avaliação motora. A amostra foi composta por 12 artigos. Foram identificados 8 instrumentos de avaliação motora, sendo que a maioria destes não são específicos para crianças com TEA. Alguns instrumentos utilizados para avaliar a função motora também avaliam outros domínios do desenvolvimento, como linguagem, função cognitiva e comportamento social. Os instrumentos relacionados apenas ao desenvolvimento motor foram o TGMD-3, a Escala Motora de Desenvolvimento Peabody e o Questionário de Transtorno de Coordenação do Desenvolvimento. Na literatura encontram-se escassos os instrumentos específicos que avaliem o desenvolvimento motor em crianças e adolescentes com TEA. Notou-se ser necessária a formulação e/ou a utilização de instrumentos específicos para avaliação do desenvolvimento motor na população estudada.
O INÍCIO DOS JOGOS ESCOLARES DO RIO GRANDE DO SUL: UMA NOVA FASE DO EVENTO ESPORTIVO ESCOLAR ESTADUAL
Authors: Oliveira Raquel Valente de , Mazo Janice Zarpellon
Published: May 2024

Os Jogos Escolares do Rio Grande do Sul (JERGS) são um evento esportivo que, atualmente, congrega estudantes da rede pública de ensino de todo o estado do Rio Grande do Sul. Resultante de demandas sociais e educacionais, as primeiras iniciativas para a criação dos JERGS ocorreram na década de 1970, quando o evento ainda possuía a razão social de Campeonato Estudantil Gaúcho (CEG). Após perpassar por uma significativa ruptura de ordem estrutural que demarcou suas conformações históricas, no ano de 1986, este evento passa a denominar-se JERGS, acontecimento este que assinala uma nova fase do evento. Diante do exposto, o presente estudo buscou investigar que fatores socioculturais e político-administrativos influenciaram na mudança de nomenclatura do Campeonato Estudantil Gaúcho no ano de 1986, quando o evento passa a denominar-se Jogos Escolares do Rio Grande do Sul. Esta pesquisa se caracteriza como um estudo de viés histórico-cultural, situada no campo de investigação da História do Esporte. As informações sobre nosso objeto de pesquisa foram obtida s por meio de fontes orais e de fontes documentais. As fontes orais foram coletadas através de entrevistas de História Oral, já as fontes documentais correspondem a documentos impressos que compõem o acervo pessoal dos agentes entrevistados. Os materiais coletados foram submetidos às técnicas de análise temática de conteúdo e de análise documental, respectivamente. Os resultados indicam que há grande probabilidade de a ruptura investigada ter sido recorrente de demandas sociais e político-administrativas pelas quais o país perpassou no ano anterior, com o encerramento da Ditadura Militar (1964-1985). Quando um novo momento político é anunciado no Brasil, transformações também são identificadas em diversas instâncias da sociedade, uma vez que dete rminações federais recaem, também, sobre os estados brasileiros e, consequentemente, sobre suas propostas e ações governamentais.

Os sintomas depressivos estão produzindo grande impacto na vida dos idosos, diminuindo a percepção de qualidade de vida nesta faixa etária. A prática do exercício físico durante o processo de envelhecimento é considerada um fator protetivo da saúde geral e da qualidade das relações interpessoais. O estudo busca realizar uma revisão sistemática da literatura e analisar a eficácia da prática do exercício como estratégia no auxílio do tratamento de idosos com sintomas depressivos. Trata-se de uma revisão sistemática conduzida conforme as recomendações do Cochrane Handbook for Systematic Reviews of Interventions e do Preferred Reporting Items for Systematic Reviews e Meta-Analyzes (PRISMA). As bases de dados consultadas foram o Pubmed, Scielo, PsycInfo e Scopus, sendo utilizado os termos de pesquisa, "exercise" OR "physical activity", "depressive disorder" OR "depression" e “clinical trial”. Foram incluídos estudos de intervenção com idosos (de idade igual ou superior a 60 anos), que apresentavam sintomas depressivos. Ao total foram identificados 10164 artigos, resultando no fim do processo de identificação 17 artigos incluídos (com indivíduos de ambos os sexos). Destes,  14 apresentaram diferença significativa, indicando que a prática do exercício físico foi eficiente na redução dos sintomas depressivos em pacientes com uso ou não das terapias padrão (psicoterapia e terapia medicamentosa). Todos os pesquisadores adaptaram as diversas categorias de exercício praticados nos estudos (caminhada livre, natação, treino de força) às fragilidades dos idosos presentes em contextos institucionais ou não. Grande parte dos estudos apontaram que a prática do exercício físico gera melhora nos sintomas depressivos, podendo ser recomendado como tratamento auxiliar às terapias medicamentosas e psicoterápicas no tratamento dos sintomas depressivos em idosos.

Published: May 2024

Este estudo discute a importância do esporte como um direito social no Brasil, destacando O Programa Segundo Tempo como uma iniciativa crucial para proporcionar o acesso ao esporte educacional de qualidade a crianças e adolescentes em situação de vulnerabilidade social. Também se discute a estratégia de gestão descentralizada que o programa utiliza, visando equidade no uso de recursos e maior autonomia dos gestores municipais. Destaca-se que a descentralização na gestão pública é um princípio importante desde a Constituição de 1988, redefinindo o papel do Estado. Nesse contexto, o objetivo foi analisar se a descentralização do Programa Segundo Tempo (PST) no sul do Brasil promoveu a democratização do acesso ao esporte educacional nos municípios de maior vulnerabilidade social da região. Trata-se de um estudo de natureza transversal, que possui abordagem descritiva, considerando que a intenção foi analisar determinadas características de uma população e estabelecer relações entre os dados encontrados. Para tanto, foi realizado um levantamento do histórico de convênios implementados no Paraná, em Santa Catarina e no Rio Grande do Sul, durante os vinte anos de existência do programa. Foram utilizados como indicadores o Índice de Desenvolvimento Humano Municipal (IDH-M) e a classe de rendimento mensal familiar. O estudo indicou que, até o ano de 2022, o Programa Segundo Tempo não esteve presente em nenhum município de maior vulnerabilidade na região. A descentralização do programa ocorreu, predominantemente, entre as cidades com nível de IDH-M elevado. Além disso, apenas em 7,9% dos municípios foram implementados núcleos do PST, apontamentos que incentivam uma reflexão sobre o modelo de gestão adotado e o direcionamento do investimento público.
Studying students' attitudes towards the use of mobile applications and online resources for learning a foreign language in higher education institutions
Authors: Tsymbal S. , Skrypnyk N.
Published: May 2024

The article deals with using mobile applications and online services for teaching foreign languages, which is becoming more and more widespread in the educational process of higher education institutions. There is a wide range of paid and free applications that are constantly being updated and developed. However, in the context of using such applications in higher education, selection and control become important tasks for a foreign language teacher. A survey of students from two universities reveals that the majority of students have experience of using mobile language learning apps, but only 67.9% recognise the positive impact on their level of knowledge. Among the disadvantages of their use are the monotony of tasks, loss of motivation, insufficient quantity and quality of information, and problems with performance stability. The analysis of the weaknesses of using mobile applications and online services for foreign language teaching points to important criteria for selecting resources for higher education teachers. First, given the different focus and functionality of applications, it is important to clearly understand the purpose and possibilities of using them as an additional teaching tool. Next, it is important to evaluate the autonomy of the app and take into account its affordability for students. Another important criterion is the ability to check assignments and track progress. The survey of students confirms a positive attitude towards the use of mobile applications, and the advantages they pointed out, such as convenience and accessibility, make these tools important for improving the process of learning foreign languages in higher education. Further research is needed to experimentally test the effectiveness of using certain mobile applications and online resources for teaching various aspects of a foreign language in the context of higher education

Authors: Avinal Sinan
Published: May 2024

Litografi baskı tekniği ya da diğer adıyla taş baskı, uzun yıllar boyunca üretim kolaylığı ve ekonomik olması sayesinde sanatsal ve ticari eserlerin üretilmesinde veya çoğaltılmasında sıklıkla tercih edilmiştir. Son yıllarda dijital baskı teknolojisinin gelişmesi litografinin ticari kullanımını azaltsa da sanatçılar için önemli bir üretim yöntemi olmaya devam etmektedir.
Kimyasal bir baskı türü olan litografi tekniği, temel prensiplerinin aynı olması sebebiyle seramik bünyelerde uygulanmak üzere geliştirilen fotolitografinin kökeni olarak kabul edilmektedir. Özellikle fotografik görsellerin seramik yüzeylere aktarılmasında kullanılması sebebiyle “Fotolitografi” adını alan bu teknik, kendine has dokusu ve birçok baskı yöntemine göre nispeten kolay uygulanabilir olmasına rağmen sanat seramiklerinde henüz yeterince yaygınlaşmamıştır. Bu çalışmada, seramik boyaları ve renk verici oksitler gibi çeşitli değişkenler ele alınarak fotolitografi tekniği uygulamaları gerçekleştirilmiştir. Yapılan denemelerin sonuçları değerlendirilerek fotolitografi tekniğinin sanat seramikleri yüzeylerinde uygulanabilirliği ortaya konulmuştur.
HEALING ROOTS
Authors: Laplante Julie
Published: May 2024

Umhlonyane, also known as Artemisia afra, is one of the oldest and best-documented indigenous medicines in South Africa. This bush, which grows wild throughout the sub-Saharan region, smells and tastes like “medicine,” thus easily making its way into people’s lives and becoming the choice of everyday healing for Xhosa healer-diviners and Rastafarian herbalists. This “natural” remedy has recently sparked curiosity as scientists search for new molecules against a tuberculosis pandemic while hoping to recognize indigenous medicine. Laplante follows umhlonyane on its trails and trials of becoming a biopharmaceutical — from the “open air” to controlled environments — learning from the plant and from the people who use it with hopes in healing.
HELMUT KOHL'S QUEST FOR NORMALITY
Authors: Wicke Christian
Published: May 2024

During his political career, Helmut Kohl used his own life story to promote a normalization of German nationalism and to overcome the stigma of the Nazi period. In the context of the cold war and the memory of the fascist past, he was able to exploit the combination of his religious, generational, regional, and educational (he has a PhD in History) experiences by connecting nationalist ideas to particular biographical narratives. Kohl presented himself as the embodiment of “normality”: a de-radicalized German nationalism which was intended to eclipse any anti-Western and post-national peculiarities. This book takes a biographical approach to the study of nationalism by examining its manifestation in Helmut Kohl and the way he historicized Germany’s past.
TRAPPED IN THE GAP
Authors: Kowal Emma
Published: May 2024

In Australia, a ‘tribe’ of white, middle-class, progressive professionals is actively working to improve the lives of Indigenous people. This book explores what happens when well-meaning people, supported by the state, attempt to help without harming. ‘White anti-racists’ find themselves trapped by endless ambiguities, contradictions, and double binds — a microcosm of the broader dilemmas of postcolonial societies. These dilemmas are fueled by tension between the twin desires of equality and difference: to make Indigenous people statistically the same as non-Indigenous people (to 'close the gap') while simultaneously maintaining their ‘cultural’ distinctiveness. This tension lies at the heart of failed development efforts in Indigenous communities, ethnic minority populations and the global South. This book explains why doing good is so hard, and how it could be done differently.

Published: May 2024

The results of the selection and variety study of pears in the conditions of the Southern Urals are considered. At the South Ural Research Institute of Horticulture and Potato Growing, a branch of the Federal State Budgetary Institution Urfanits Ural Branch of the Russian Academy of Sciences, breeding work was carried out to improve the assortment of pears for the Ural region. As a result of many years of breeding work, the range of fruit and berry plants was replenished with a new pear variety, Favoritka, which in 2022 was included in the State Register of Breeding Achievements approved for use. In the process of breeding work, the winter hardiness of pear varieties in the harsh climatic conditions of the Chelyabinsk region was studied, as a result it was noted that infield conditions when the temperature dropped to -40 ° C, freezing of trees of local varieties did not exceed 1 point. An assessment was made of the yield of local varieties, among which the following varieties stand out: Vekovaya, Myth, Favoritka, and Zolotoy Shar, with an average yield of 24 - 28 kg per tree. The economic indicators of the Favoritka pear variety (profitability level of 253.5%) indicate its suitability for cultivation in both industrial and amateur gardening in the Ural region. A pomological description and assessment of the economic usefulness of the new Favoritka pear variety are presented, which combines large fruit (fruit weight can reach 340 g), high winter hardiness, productivity, resistance to abiotic and biotic stressors (not affected by scab, resistant to pear gall mite), has fruits of excellent taste, suitable for fresh consumption, as well as for processing (preparing jams, preserves, compotes, etc.). The variety is in demand among the population and is of interest as a source of giant fruit in further breeding work.
Methodological bases for balanced development of the food supply of the population
Authors: Baskakov S. M.
Published: May 2024

A retrospective analysis of the economic theories of marginal utility, general economic equilibrium, spatial economics, production factors, and organization theory was carried out from the position of forming the methodological basis for the emergence of the theory of balanced development of food supply for the population. The substantive aspects of the critical concepts of the identified theories are detailed in their influence on the formation and formation of the methodology for food supply to the population, including maintaining a balanced and equilibrium state in the conditions of continuous influence of external factors on food systems. For each identified theory, provisions have been established that determine the relationship with the methodology of the area under study. It has been established that the emergence of the theory and methods of balanced development of food supply for the population is a natural stage in the evolution of economic science in the context of increasing the role and importance of man in the modern economy. The methodological grounds identified are the need to achieve and maintain a balanced human diet, ensure coordination and maintain a balance of social and economic interests of consumers and food producers, ensure a balanced state of food production and consumption, maintain a balance of resource capabilities and future food needs of people, prevent the emergence of imbalances in the food sector. The work results can be used to develop new conceptual frameworks for developing the domestic agro-industrial complex and allow us to form a more holistic and detailed understanding of the specifics and features of achieving balanced agri-food sector development.

Secondary raw materials for sugar production and directions for its processing
Authors: Ermolaev V. A.
Published: May 2024

The article is devoted to a review of literature data on the problem of environmental safety of sugar production. The main types of waste generated during sugar production are considered. Some areas of processing and disposal of sugar production waste, such as beet pulp, filter cake, molasses, beet tailings, and wastewater, are given. Beet pulp is mainly dried and used to manufacture feed for farm animals. It can be used to obtain powdered semi-finished products in the food industry and the production of fertilizers. Filtration sediment is used to improve the quality of the soil-biotic complex of leached chernozem. Molasses is also a byproduct of sugar production, containing about 50% sucrose. Therefore, it becomes advisable to extract sugar from molasses, subject to economic benefits. Inexpensive and uncomplicated methods for removing sugar from molasses include lime separation, precipitation of sucrose using acetic acid, and barite and strontium methods for extracting sugar from molasses. Wastewater from sugar factories can be used for irrigation. However, given that the sugar beet processing season does not coincide with the growing season, to irrigate fields with wastewater, it is necessary to build unique storage ponds, settling tanks, and pumping and irrigation systems, which require additional costs. Another type of waste is generated when sugar beets are processed: beet tailings. This type of waste is usually used to obtain additional sugar or feed farm animals. The tailings are collected on a rotary beet catcher, passed through a sorting classifier, and sent for processing. The fine fraction is sent with the pulp for dehydration or to pulp pits for feeding livestock.
Seeing Through the Eyes of Classroom Observers: The Case of Rating Contrasted Groups of Lessons With Classroom Observation Measures
Authors: Lynch Kathleen
Published: May 2024

Classroom observations are commonly employed to assess quality of instruction in research and practice in mathematics education. However, there is more to be learned about how sensitive classroom observation protocols are to exemplars of strong mathematics instruction, and continuous refinements to observation protocols or rating processes that may be warranted. In this study, we use the public-released mathematics videos from the Third International Mathematics and Science Study (TIMSS) to examine how classroom observers, using two contemporary classroom observation instruments, rate a set of lessons whose instructional quality is in theory expected to differ, also referred to as contrasted groups. We find that descriptively, the pattern of findings is distinct from prior studies’ conclusions about the relative instructional quality reflected in the TIMSS video pool. We provide qualitative examples to illustrate the findings, and discuss implications for future research. We point to the potential value of exploring classroom observation rubrics’ performance using ‘contrasted groups’ of lesson videos, as a tool to broaden our understanding of how observation instruments are functioning.
