Mapeamento e caracterização de trilhas na fazenda Salambaia como subsídio ao desenvolvimento do geoturismo e da geoconservação no semiárido paraibano
Authors: Porto Valeria Raquel , Albuquerque Xavier Rafael , Leite de Souza Nadson Ricardo
Published: April 2023

As trilhas representam uma prática bastante comum no contexto do geoturismo, muitas vezes são executadas de maneira improvisada, sem que o visitante tenha informações sobre as características e o grau de dificuldade dos trajetos. O artigo objetivou identificar, descrever, mapear e classificar as trilhas da Fazenda Salambaia, no Semiárido Paraibano, visando o aperfeiçoamento das atividades geoturísticas e o consequente aumento da atenção voltada à conservação da geodiversidade. Visitas guiadas in loco foram realizadas para a identificação dessas trilhas e seus atrativos mais expressivos, que foram mapeados com um aparelho de GPS, nas funções tracklog e trackpoints. Os graus de dificuldade foram estabelecidos através da proposta metodológica de Silva (2016), adaptada aos softwares livres QGis e Google Earth Pro. Foram identificadas três trilhas, a “Trilha da Amélia”, a “Trilha da Muralha” e a “Trilha Rupestre”, e representadas de acordo com os graus de dificuldade, detalhados em cada fragmento, que variaram desde trechos “muito fáceis” até “muito difíceis”.

Authors: Milanez Bruno , Jardim de Moraes Wanderley Luiz , Magno Lucas
Published: April 2023

O presente artigo tem como objetivo debater algumas políticas públicas e projetos de lei para a mineração que estiveram em pauta nos governos de Michel Temer e Jair Bolsonaro, bem como suas consequências. A partir de revisão bibliográfica, dados secundários e análise documental o texto faz, inicialmente, uma breve caracterização da espacialização dos conflitos associados à mineração, em particular envolvendo povos indígenas, e apresenta os Territórios Livres de Mineração como uma outra forma de se pensar o uso dos territórios. Em seguida, uma avaliação institucional descreve a influência corporativa sobre o Estado e seus principais resultados. Então, o artigo sistematiza questões que carecem de uma discussão crítica, incluindo, a mineração em Terras Indígenas, a insegurança dos complexos minerários; a injustiça fiscal e tributária; as fragilidades do licenciamento ambiental; e os retrocessos causados pela reforma trabalhista. Por fim, são organizadas propostas para o aprofundamento do debate sobre esses temas.
Diálogos entre Henri Lefebvre e as perspectivas feministas
Authors: Silva Joseli Maria , Ornat Marcio Jose
Published: April 2023

O objetivo deste artigo é evidenciar aproximações entre as proposições de Henri Lefebvre, um dos mais influentes teóricos da geografia brasileira e a vertente feminista. Fazemos isso trazendo a relação entre espaço absoluto e espaço diferencial, demonstrando a centralidade do corpo em sua teoria e posteriormente correlacionamos suas proposições com os apontamentos feministas sobre a ética do cuidado da vida e o amor como elementos de transformação social e espacial. Esse desafio se coloca como importante no contexto epistemológico brasileiro da ciência geográfica a fim de construir identidades científicas e amenizar as hostilidades crescentes dirigidas ao ideal feminista em uma conjuntura social e política crescentemente conservadora no Brasil.
Emergência climática: desafios e oportunidades no campo do ensino de geografia
Authors: Mendonça Francisco , Oscar Junior Antonio Carlos , Gomes Hemerson Souza
Published: April 2023

Os cenários das mudanças climáticas globais, atualmente concebidas como emergência climática, indicam intensificação dos eventos extremos em todo o planeta, no presente e no futuro. Os impactos e riscos associados ao fenômeno tendem a se fazer mais expressivos sobre as populações pobres do Sul Global devido, especialmente, à alta e altíssima vulnerabilidade socioambiental das populações destas áreas. O tema está presente nos conteúdos do ensino de geografia estabelecidos pela BNCC, embora ali tenha um enfoque sobretudo tecnicista; os professores de geografia podem promover uma abordagem crítica do tema, envolvendo os estudantes em atividades de sala de aula e extra-classe. O ensino de geografia pode contribuir em muito para um conhecimento efetivo e real do fenômeno, fato que contribuirá para uma melhor sensibilização e conscientização dos estudantes em relação ao problema, e também para ações de mitigação e adaptação às mudanças climáticas.
Mulheres e o mundo do trabalho
Authors: Caetano Daisy Luzia do Nascimento Silva , Scremin Martins Lucinéia
Published: April 2023

Em épocas de crises de qualquer ordem os direitos conquistados pelas mulheres são mais atacados com tendência a retrocessos. No Brasil as mulheres seguem mobilizadas e vigilantes para a manutenção e avanço dos direitos, mas após o golpe jurídico-midiático-parlamentar em 2016 a situação tem piorado. A diminuição de políticas públicas e o avanço do discurso machista na sociedade gerou o aumento da violência contra a mulher. Ao mesmo tempo ocorre o aprofundamento da divisão social do trabalho que mantém as mulheres, sobretudo as negras, com os piores salários e condições de trabalho, sem garantias para os direitos reprodutivos e para a maternidade saudável e sem possibilidades de uma vida plena. Pelo prisma geográfico contribuímos pensando a necessidade de políticas públicas para a igualdade de gênero.

Os circuitos da economia urbana em Londrina (PR)
Authors: Cocato Guilherme Pereira
Published: April 2023

Este estudo propõe uma abordagem analítica sobre as formas espaciais do comércio nas cidades, que podem ser consideradas como representantes dos dois circuitos da economia urbana. Foram escolhidos dois tipos de estabelecimentos: as revendas de produtos usados, do circuito inferior, e os shoppings centers, do circuito superior. Como recorte espacial, foi selecionada a cidade de Londrina-PR, pela relevância histórica e contemporânea da presença diversa de atividades terciárias e, mais especificamente, comerciais. Nos procedimentos metodológicos, uniram-se a discussão teórico-conceitual e fontes de dados heterogêneas, como o CNEFE e a RAIS, amparados pelas definições da CNAE, à representação cartográfica. Busca-se evidenciar a distribuição dos estabelecimentos comerciais, os processos espaciais dos quais fazem parte e as dinâmicas socioeconômicas que os envolvem no exercício de suas atividades. Entende-se que o trabalho pode contribuir com a Geografia pela amálgama de elementos teórico-metodológicos indispensáveis a qualquer análise que se preze como significativa ao cotidiano urbano.
A Zoogeografia do Brasil e suas relações com as áreas naturais
Authors: Marques Neto Roberto
Published: April 2023

A espacialidade da fauna tem sido pouco explorada na Biogeografia brasileira, com acentuado esvaziamento da discussão a respeito do papel dos animais na diferenciação de áreas, na composição das paisagens e nos processos de superfície. Visando tais aproximações, o presente artigo tem por objetivo discutir as relações espaciais entre a biota animal e as regionalizações e áreas naturais em perspectiva interescalar. Para tanto, as províncias zoogeográficas brasileiras foram comparadas em suas aderências e incongruências espaciais com outras regionalizações físico-geográficas (domínios morfoclimáticos, compartimentação morfotectônica, regiões biogeográficas e macroespaços agroecológicos) a partir do coeficiente de Jaccard, aplicado a diferentes ordens de mamíferos terrestres. Subsequentemente, a espacialidade da biota animal foi discutida em escalas regionais, cotejando relações entre padrões distributivos no macroespaço amazônico e no domínio tropical atlântico, tendo a ordem Primates como táxon de referência. Por fim, também foram contempladas integridades distributivas mesorregionais a partir do aporte teórico dos geossistemas, referenciando-se na ordem Rodentia. Os resultados mostraram aderências nas diferentes escalas, apresentando fortes congruências no conjunto dos macroespaços brasileiros, em domínios específicos, bem como na escala da paisagem, referenciada a partir dos macrogeócoros.
Desastre ambiental e zonas de sacrifício
Authors: Knox Winifred , Ferreira José Gomes
Published: April 2023

O artigo analisa o derrame de petróleo vivenciado no Brasil entre agosto de 2019 e janeiro de 2020, as políticas públicas frente a desastres deste tipo, seus impactos na população litorânea pesqueira, e as ações do governo frente ao incidente ambiental que devido às suas grandes proporções tem sido considerado um dos mais amplos em termos de efeitos socioeconômicos e ambientais na região Nordeste e no Brasil. Objetivamos analisar a exposição à fragilidade do território brasileiro relacionado a uma política de constituição de zonas de sacrifício, fundamentada por uma narrativa econômica ultraliberal de enxugamento do Estado, que se operou através de desmonte de arranjos institucionais e políticas públicas para incidentes de óleo.. Conclui-se que o desmonte dos arranjos institucionais resultaram em uma ação tardia, evidenciando dificuldades de articulação entre as instituições cabíveis, causando o avanço crescente das manchas e grandes efeitos no litoral para entes humanos e não humanos.

Editorial: The Culture of Linguistic Literacy Development as an Indicator of Society's Consciousness: A Comparative Aspect
Authors: Biloshkurskyi Mykola
Published: April 2023

Perspectives of modern linguistic literacy in the context of integration shifts are directly related to the process of social modernization and the problems of forming critical thinking. Linguistics and the language of communication have a powerful and contradictory influence on the education of the younger generation, often becoming a leading factor in its socialization and social learning. The formation of a person's linguistic literacy should be based on the main provisions - principles that determine: the system of requirements for linguistic means and conditions as a specific educational direction; a system of requirements for the content, organization and methodology of teaching linguistics of the educational course.
Numerical Simulation of the Production of Core-Shell Microparticles
Authors: Fernandes Célio , Ferrás Luis L. , Afonso Alexandre M.
Published: April 2023

Conventional methods that are commonly used for the preparation of microbubble delivery systems include sonication, high-shear emulsification, and membrane emulsification. However, these methods present significant disadvantages, namely, poor control over the particle size and distribution. To date, engineering core-shell microparticles remains a challenging task. Thus, there is a demand for new techniques that can enable control over the size, composition, stability, and uniformity of microparticles. Microfluidic techniques offer great advantages in the fabrication of microparticles over the conventional processes because they require mild and inert processing conditions. In this work, we present a numerical study based on the finite volume method, for the development of capsules by considering the rheological properties of three phases, air, a perfluorohexane (C6 F14) and a polymeric solution constituted of a solution of 0.25% w/v alginate. This methodology allows studying the stability and behavior of microparticles under different processing conditions.
A Morte Antecipada na Forma de Feminicídio: Pelo Direito à Justiça, à Verdade e à Memória.
Authors: Mariano Silvana , Souza Márcio Ferreira
Published: April 2023

A morte é, por vezes, produto de um assassinato, a exemplo do feminicídio, uma morte socialmente construída e, muitas vezes, tolerada, ou justificada. No, presente artigo, temos como objetivo articular a sociologia da morte com a sociologia da violência para introduzir gênero e patriarcado como noções relevantes para as reflexões, nas Ciências Sociais, sobre a morte e o processo de morrer, buscando, igualmente, a compreensão estrutural sobre a morte produzida nas relações de poder que levam ao feminicídio, como forma de morte antecipada de mulheres. Como resposta à ordem social e jurídica que invisibiliza ou culpabiliza a vítima, a perspectiva vitimológica apresenta-se como recurso analítico em defesa do direito à justiça, à verdade e à memória. Com base em estudos empíricos sobre casos de feminicídios consumados julgados na Comarca de Londrina nos anos de 2021 e 2022, demonstramos como o poder patriarcal, traduzido na objetificação, coisificação e menosprezo de meninas e mulheres, produz feminicídios no contexto da violência doméstica e familiar e como, na resposta formulada judicialmente, apresentam-se riscos de naturalização, invisibilização e revitimização das mulheres.

Bridging Learning Opportunity Gaps (BLOG) Project: A Pandemic Remedial Intervention in Junior High School Science
Authors: Singua Charlie
Published: April 2023

This study focused on the perceptions of teachers and students on the Bridging Learning Opportunity Gaps (BLOG) Project as a pandemic remedial intervention in the Junior High School (JHS) Science implemented in the Schools Calbayog City Division, Department of Education, Philippines during the school year 2021-2022. This was in the attempt to provide insights into the state of remedial education in the Philippines. The study used the descriptive-correlational research design and handed out survey questionnaires to 38 teacher and 70 student-respondent across seven public schools in Calbayog City. The findings reveal that although both the teacher and student-respondents manifested highly positive perceptions on the BLOG Project in Science in all parameter set, the teachers, as implementers were more positive in their assessment while the students as the subjects were slightly more critical. It also has been noted thar despite the positive evaluation, both the student and the teacher-respondents reported experiencing various problems in the implementation of Project BLOG. For the teachers, their biggest dilemma was the fact that they attend to the specific needs of each learner due to the limitations of the current educational set-up. For the students, it was the changing community quarantine classifications and policies that may hinder the continuity of the Project BLOG in Science. Overall, the study concludes that the Project BLOG was satisfactorily implemented and further supports the literature on the efficacy of remedial instruction

Published: April 2023

This study was performed on 24 calves aged about 30-100 days old, fourteen calves were suffering from signs of pulmonary affections including fever, bilateral muco-purulent nasal discharge, cough and abnormal lung sounds upon auscultation and these calves were enrolled as pulmonary affected group. The other ten calves were apparently clinically healthy as proved by clinical examination and were used as a control healthy group. Blood and serum samples were collected from healthy and diseased calves (before and after treatment). Hematological analysis of diseased calves before treatment showed a significant decrease in the value of RBCs and Hb, with no significant changes in the value of PCV between healthy and diseased calves before and after treatment. The total leucocytic count showed a significant increase in its value in diseased calves with significant increase in neutrophils and lymphocyte (%) as compared with healthy ones. Serum biochemical analysis of pulmonary affected calves showed hypoproteinemia, hypoalbuminemia, hypoglycemia, hyponatremia, hypochloremia and hyperkalemia as compared with healthy control calves. Activities of serum AST, ALT showed significant elevations in pulmonary affected calves with no significant changes in levels of total and direct bilirubin as compared with healthy calves. Analysis of acute phase protein of diseased calves before treatment showed a significant increase in values of Haptoglobin (Hp), serum amyloid A (SAA), Ceruloplasmin (Cp) and C - reactive protein (CRP) as compared with their levels after treatment and in healthy calves.
DETERMINING THE ROLE OF HLA-B27 ON COVID-19
Authors: karahan do , demir bilgehan
Published: April 2023

OBJECTIVE: Human leukocyte antigen-B27 (HLA-B27) binds antigenic peptides in the structure of some viruses and presents them to cytotoxic T lymphocytes and plays a role in the immune response against these viruses. It has also been found to be associated with auto-immunity as an inverse relationship and is associated with a number of auto-immune inflammatory diseases, especially Ankylosing Spondylitis (AS). Our aim in this study is to determine the role of HLA-B27 in Severe Acute Respiratory Syndrome (SARS)-Cov-2 (Coronavirus Disease-COVID-19).
METHOD: 90 HLA-B27 positive and 96 HLA-B27 negative cases were included in the study. COVID-19 Polymerase Chain Reaction (PCR) results and Thorax Computed Tomography (CT) results, hospitalization and death records of the cases were retrospectively analyzed from the system records. Results were compared between HLA-B27 positive and negative groups.
RESULTS: Of the HLA-B27 positive cases, 32.2% had COVID-19 positivity, 5.6% had COVID-19 lung involvement. 44.8% of HLA-B27 negative cases had COVID-19 positivity and 11.5% had lung involvement. There was no significant difference between the HLA-B27 positive and negative groups in terms of having COVID-19 infection, lung involvement, hospitalization and death rates.
CONCLUSION: The results of our study show that HLA-B27 does not have a protective role in terms of having COVID-19 and lung involvement. Again, since no auto-immunity-related SARS was observed in any of the patients, it can be said that it did not increase the severity of the hyper-immunity-related disease and did not increase the risk of death in particular for COVID-19. These results need to be supported by more studies.

Authors: Manoharan Nithyapriya , L Madhan , Sain Sanu , R Malarvizhi
Published: April 2023

Background: In an array of clinical diseases, pain management becomes increasingly complicated. The stimulation of glial cells and associations between neuroglial cells are emerging as being part of the primary mechanisms of pain. It has been observed that the tetracycline antibiotic minocycline inhibits microglial activation and thereby decreases nociception.

Aims and Objectives: The primary purpose of this study is to assess and compare the antinociceptive activity of minocycline with that of the conventional analgesic tramadol in Swiss albino mice.

Materials and Methods: Twenty-four Swiss albino mice in total were allocated into four groups, each including six mice. Using Eddy’s hot plate plus tail-flick procedure, the analgesic effects of tablet minocycline 5 mg/kg and tablet minocycline dose 10 mg/kg were assessed and compared to those of tramadol. Recordings of reaction time observations are made both before and after the administration of drugs. Results of a statistical analysis were obtained.

Results: Results of our study showed that in the tail-flick plus hot plate procedures, minocycline in doses of 5 mg/kg and 10 mg/kg had a significant (P < 0.05) antinociceptive effect in Swiss albino mice. However, the antinociceptive effect of minocycline is more when compared to distilled water, and is less when compared to standard analgesic tramadol.

Conclusion: Minocycline showed significant antinociceptive activity in both doses in Swiss albino mice.

Published: April 2023

Background: Due to lack of consensus of teaching learning methods during undergraduate period, intern doctors face many challenges in clinical settings. Knowledge gaps related to clinical application of laboratory medicine leads to poor case management. Active learner centered training with real clinical cases is a need to help the interns to link their basic science knowledge into a practical context.

Aims and Objectives: The present study was done to evaluate the effect of case based learning (CBL) on the interns’ knowledge and clinical decision-making skill of interpretation of laboratory investigation reports and to assess perception of participants about CBL.

Materials and Methods: CBL method was used to train the interns in clinical application microbiology reports. This is a pre- and post-test type study, carried out for 2 months with 43 Medical interns, willing to participate. The process included evaluation of CBL by pre-validated questionnaires by multiple choice questions, clinical case scenarios before, immediately after and 10 days after the intervention and perception toward CBL was assessed. Statistical analysis was done using Student’s t-test and SPSS 17 software. The value of P < 0.05 was considered as significant.

Results: A significant improvement in the interns’ knowledge and problem solving following CBL sessions had been observed in present study. The post-test scores of all the CBL sessions were significantly higher than pre-test scores (P < 0.05). The perception of interns toward CBL was assessed and it was responded positively. It helped in strengthening the critical skills of interns such as problem solving, critical thinking, and teamwork.

Conclusion: The present study proved that interns during internship require to be trained in laboratory medicine. CBL is an effective teaching method to train interns in enhancing their problem solving skill with correct use of laboratory test results and strengthening critical thinking, teamwork, and time management skills.

Published: April 2023

Briquetting of agro-residues can alleviate some of the problems of energy shortage being encountered world-wide. The briquettes are essentially manufactured to provide cheap energy to the various sectors. Most importantly, to the domestic households that are finding it difficult to purchase the other sources of energy because of their cost. In this research the briquettes wereproduced in a briquetting screw press –BSP, using a manually operated piston and cylindrical shape Mould. The individual materials weremixed thoroughly in a ratio of rice husk: groundnut shell (RH:GS) as follows: 100:00; 70:30; 50:50;30:70; and 00:100.A fixed quantity of each mixture wereseparately hand-fed into a manually operated closed-end piston press to compact the briquettes. Thereafter, the briquettes wereejected and placed on drying racks and left in the sun for drying. The moisture content, ash content, volatile matter, fixed carbon, ignition time,flame propagation time, calorificvalue and water boiling test were investigated to determine the physical and thermal properties of the briquettes produced. The results of the investigation showedthat moisture content of the briquettes ranged from 3.96 –5.65%, the calorific value ranges from 130, 63.56–141, 62.87kJ/kg, the range of ash content is 6.10 -9.32 %, for fixed carbon is 7.67 -20.20 %, the ignition time ranges from 238-270sec and the rangesfor water boiling test time is 10.57m, –13.37m. These values satisfactorily comparewell with values obtained by other researchers in the literature. Therefore, the rice husk -groundnut shell briquettes are good alternative source of thermal energy for cooking. It is an economical and also an environmental friendly source of energy and waste disposal.
Poeter versus skådespelare i Dagens dikt 2020–2021
Authors: Svensson Jimmie
Published: April 2023

“Poets versus Actors Reading Poetry on Swedish Radio 2020–2021”
Following the rise of the poet as the principal performer of his or her own work, in the second half of the 20th century, actors have been criticized for performing poetry as if acting on stage, or for focusing too much on conveying the lyric I. This primarily quantitative study investigates what prosodic differences there are between poets and actors reading poetry. The material consists of 276 readings from the Swedish public radio program Dagens dikt (The Daily Poem), from 2020 and 2021. A set of prosodic measures are produced for each recording with computational aid, and the groups are compared by using descriptive statistics. The differences found in terms of tempo and pausal patterns, though small, suggest that the actors read in a conventionally poetic, expressive style, while the poets are closer to a style typical of prose reading and conversational speech; this might be connected to differences between their respective repertoire – the poets reading newer, longer, and possibly more narrative texts. When it comes to pitch, there are more substantial differences: the poets are more monotonous and their tonal patterns more predictable, indicating a formal, less expressive style. These traits are associated with the highly stylized vocal cliché Poet Voice, which in turn is connected to poetological shifts in the last few decades. In both groups, however, younger individuals (born 1970 or later) and women, respectively, are the more monotonous and predictable; this might suggest a sociolinguistic trend not limited to poetry. Qualitative, close listening to a selection of readings largely confirms the findings of the quantitative investigation. While the frequently idiosyncratic poets tend to highlight form, such as rhythm and tonal repetitions, the actors rather try to convey the content of the poem, in accordance with prosodical and performative conventions.

Lưới điện microgrid đang là xu hướng phát triển trên thế giới cũng như ở Việt Nam trong thời gian gần đây. Lưới điện microgrid có ưu điểm là có khả năng tích hợp các nguồn năng lượng tái tạo, thân thiện với môi trường, và đặc biệt phù hợp ở những khu vực đảo xa, nơi mà phương án cấp điện từ đất liền là không khả thi. Tuy nhiên, việc lập kế hoạch và vận hành lưới điện microgrid nhằm tối ưu hóa về chi phí sản xuất đang là nhiệm vụ đầy thách thức. Trong bài báo này, lưới điện microgrid huyện đảo Bạch Long Vỹ được sử dụng làm mô hình nghiên cứu. Ba kịch bản cấp điện cho lưới điện huyện đảo Bạch Long Vỹ được so sánh và đánh giá. Phần mềm Homer được sử dụng để đánh giá các chỉ tiêu kinh tế của các phương án. Kết quả đánh giá cho thấy phương án tích hợp thêm nguồn năng lượng hydrogen vào hệ thống đang hiện hành trên đảo là phương án tối ưu về giá thành sản xuất. Bên cạnh đó, phương án này còn giảm thiểu được lượng khí phát thải từ các máy phát điện diesel.

The results of the bivariate test using the somers'd correlation test between the level of knowledge and attitudes obtained p value = 0.003 (<0.05). The results of the correlation test between the level of knowledge and behavior obtained p value = 0.001 (<0.05). Based on the results of this study, it can be seen that there is a significant relationship between knowledge and attitudes and behavior of the community towards preventing the COVID-19 pandemic in the working area of the Pasar Merah Health Center.
Integrating Divergent Assessment (DA) and Task Based Language Teaching (TBLT) in Argumentative Essay Writing Classrooms: An Experimental Study to Develop Iraqi EFL Learners’ Writing Skills
Authors: Bagheridoust Esmaeil , Al-Sultani Hossam
Published: April 2023

The researchers delved into the practice of divergent assessment (DA) and participation in assessment while emphasizing task-based language learning (TBLT) as instruction in argumentative essay courses in an Iraqi EFL context. In doing so, they formed 3 classes, namely a traditional class, a DA exercise with a traditional class, and a TBLT exercise with a traditional class, to investigate the differences that such practices can induce in the writing quality of EFL learners. performance Post-test analysis and one-way ANOVA show that the CONV TBLT class (M = 3.97) significantly outperformed the CONV DA group (M = 2.98) in terms of better argumentative writing. This study shows how EFL learners respond to the integration of DA and TBLT with compliant writing instruction. The researchers used two parallel argumentative writing tasks before and after the DA and TBLT treatment. The results of the study rejected the researchers' null hypotheses, showing that both DA and TBLT were reliably effective in increasing Iraqi EFL students' argumentative essay excellence, with TBLT having a slightly higher neck than DA. The final result of the study clearly shows that the CONV TBLT group showed a significantly higher mean score than the CONV DA and CONV groups. The CONV DA group showed a significantly higher mean score than the CONV group.

The objectives of this research were as follows: (1) to develop learning activities in science and technology subjects using inquiry-based learning for seventh-grade students (12-13 years old); (2) to develop academic achievement for the topic of elements and compounds using inquiry-based learning management activities to meet the 70% requirement; and (3) to assess the satisfaction of seventh-grade students who are taught with inquiry-based learning management. The target group of this study was 24 seventh-grade students on the science and technology course. The research tools included seven inquiry-based learning management plans, an achievement test, and a satisfaction assessment. The results show that synthesizing the approach to learning management using inquiry-based learning led to the formulation of learning activities. Students had better academic achievement, with a mean score of 81.45%, which was above the 70% requirement. Students were satisfied with inquiry-based learning activities, with an average of 4.75 and a standard deviation of 0.48, which is the highest level.

Authors: Reiser-Bello Zago Elisabeth , Keller Annina
Published: April 2023

Während hierzulande in Schulsprachendebatten oft über Erstsprachen von Kindern diskutiert wird, ist nur wenig darüber bekannt, wie migrationsbedingt mehrsprachige Studierende ihre Herkunftssprachen erleben. Anhand einer Umfrage an der Hochschule für Wirtschaft Freiburg wurde diese Zielgruppe zur Rolle ihrer Herkunftssprachen im – offiziell dreisprachigen – Studienalltag befragt. Wünschen sie sich etwa, dass diese Sprachen in den Kursen berücksichtigt werden? Die Resultate zeigen, dass die Studierenden ihre Herkunftssprachen im privaten Umfeld wertschätzen. Die Mehrheit ist allerdings der Meinung, sie hätten im Studium und auch am Arbeitsplatz keinen grossen Platz.

ORNITHOLOGICAL RESEARCH IN THE MID REACHES OF THE ARAKS RIVER IN ARMENIA
Authors: Balyan L. B.
Published: April 2023

The Araks River is the main water artery in Armenia sharing a nearly 150 km border with Turkey. Its mid reaches historically served important passage grounds for migratory waterbirds. However, the left banks of the Araks River within its border strip have not been surveyed since the late 1960s due to restricted access. The research aimed to survey the species diversity of waterbirds and their habitats preferences along the river shoreline. In 2020 and 2021, a total of 55 waterbird species from 13 families have been observed. Their abundance peaked in summer and declined in midwinter which was due to reduced habitat availability during these seasons in the Ararat valley. The current research revealed that despite nesting grounds for waterbirds are limited along the length of the shoreline, the river continues to provide important stopover and foraging grounds for diverse groups of waterbirds before and during the periods of migration.

Extant literature on schadenfreude, a pleasure towards the misfortune of others, is concentrated on brand rivalry however is silent about situations when one own brand causes the schadenfreude. Based on brand relationship theory we advance knowledge on this topic by investigating how one brand’s bad malicious strategy leads to schadenfreude for admired and non-admired brands and is mitigated when admired brands interact with positive feelings elicited by brand-consumer relationship to protect against their own bad behavior. Through three experimental studies we point out the feelings elicited exact region of moderations. The first study tests the mitigating effect of congruence between brand and Self. Study two tests higher-order affective levels such as brand love, as a negative moderating construct for schadenfreude. Study three advances previous studies on consumers’ self-promoting feelings and their interaction with brands to produce schadenfreude. Finally, we discuss the findings and further directions for research on schadenfreude.
