Abstract The current research work aims to provide knowledge about the diversity of spiders’ fauna and their occurrence throughout the year from District Charsadda Khyber Pakhtunkhwa, Pakistan. Research data were collected from March-2015 to January-2017 from seven different localities of Charsadda District by using the camera, bottle, plastic bags, paraffin films, field book and 70% of ethylene alcohol and 20% of glycerine were used as chemicals. By using special identification keys, spiders were differentiated into families, genera and species. During the study time, a total of 2734 specimens of spiders were collected belonging from 35 genera, 15 families and 44 species were identified. Salticidae was the dominant family according to genera studied plus spiders samples numbers collected with 10 genera and 616 species specimens count. The high occurrence of spiders was studied during July. The result of the current study also shows a reduction of spider’s species in December due to lowering the temperature. The current study shows that Salticidae were the dominant family as capered to other species. The occurrence of spiders species greatly depends on changing the weather condition. The present study also shows great fluctuation in spider’s occurrence with changing of hot climate to colder during the study duration. Moreover, the wet season plays a great role in spiders’ population increase and growth.

Abstract Cotton mealybug is a highly invasive pest of agricultural crops worldwide. Major agriculturists most rely on the use of insecticides for the control of pesticides. So, the indiscriminate use of insecticides leads to resistance development in recent years. For this purpose, an experiment was conducted using different concentrations of the three insecticides (profenfos chlorpyrifos and triazophos) to check the hormoligosis effects against cotton mealybug (CMB) in laboratory conditions. Investigation of variations for % mortality of adults of CMB after three days revealed that all treatments had statistically significant (P ˂ 0.05). The highest mortality was observed at the highest concentrations of profenofos 2.4% (38.55%). After 7 days, all the treatments were significant with difference in means (P ˂ 0.05). The highest mortality was recorded at the highest dilution of pesticide profenofos 2.4% (77.11%). The values of fecundity and longevity exposed a valid difference among treatments (P ˂ 0.05). Maximum fecundity was observed at the concentration 2.4% (181.41%) and longevity showed (38.46%). The highest mortality was observed at a concentration of triazophos 4% (27.98%). For chlorpyriphos the highest mortality was examined at concentration 4% (24.79%). The fecundity showed a statistically significant difference for different concentrations of triazophos and chlorpyriphos (P ˂ 0.05). The results of the recent study provide valuable information regarding the selection of insecticides and hormoligosis effects. The study can be helpful in the implications of integrated pest management of P. solenopsis.

Published: May 2022

Abstract The aim of this study was to compare three methods of processing thermographic images for the evaluation of carpal temperature in healthy calves. Additionally, we sought to evaluate the thermal symmetry between the contralateral carpi of these calves. Thermographic images were obtained from both carpi of eight healthy calves aged between 20 and 45 days with a mean weight of 38.65 ± 2.27 kg. Using GRAYESS® IRT Analyzer 7 software, the total temperature (Ttot), region-of-interest temperature (Troi), and maximum mean temperature (Tmax) were determined. There was no difference between the temperatures obtained by the Ttot and Troi methods. Tmax showed higher temperatures (p < 0.01) than the other methods. The three image processing methods showed high and significant positive correlations for the temperature of the right and left carpi of healthy calves. Tmax presented a higher correlation coefficient (r = 0.99) than the two other methods, which suggests a greater sensitivity for identifying thermal variations among the contralateral carpi. The 99% confidence interval for the difference between the temperatures of the right and left carpi (∆r-l) was between 0.03 and 0.26°C; thus, a temperature variation within that range does not refer to pathologic processes.

Published: May 2022

Resumo Este estudo avaliou os efeitos da dominância social sobre o comportamento do estro e os parâmetros ovarianos de cabras leiteiras submetidas à indução sincronizada do estro durante a estação não reprodutiva. A sincronização foi induzida em 23 cabras leiteira alocadas em baias coletivas. A ultrassonografia foi realizada em intervalos de 12 horas desde a remoção do dispositivo até a ovulação. Após a detecção do início do estro (EO), as cabras foram imediatamente removidas dos currais. A dominância foi pontuada de acordo com EO em relação à remoção do dispositivo, sendo: HD - alto dominante (<36 h; n = 8), MD - médio dominante (36 a 48 h; n = 10) e LD - baixo dominante (>478 h; n = 5). As cabras em estro foram inseminadas artificialmente em tempo flexível (FxTAI). O intervalo de estro foi maior (P<0,05) em LD (53,7 ± 6,5 h) do que em MD (37,9 ± 5,5 h) e cabras HD (32,3 ± 6,6 h), por sua vez, o intervalo entre a remoção do dispositivo e a ovulação foi semelhante (P> 0,05) em todos os grupos. O intervalo de EO a FxTAI foi maior em cabras HD quando comparado aos outros grupos (P<0,05). Em conclusão, embora a hierarquia social tenha influenciado o tempo de início do estro, os parâmetros ovarianos incluindo a ovulação não foram afetados.

ABSTRACT Objective: to identify the prevalence and factors associated with late diagnosis of the infection by the Human Immunodeficiency Virus (HIV), in a municipality of São Paulo. Method: an epidemiological, analytical and retrospective study that analyzed the HIV and AIDS cases notified by the health services in the period from 2015 to 2017 using data from the notifications of the Information System for Notifiable Diseases (SINAN Net) corresponding to the users recently diagnosed with HIV/AIDS infection in the municipality of Ribeirão Preto/SP, Brazil. Data collection was in May 2018. The chi-square test was performed, as well as binary logistic regression, where the dependent variable was the AIDS criterion at the moment of notifying infection by HIV. A p-value<0.05 was considered for the association between the variables studied in relation to late diagnosis. Results: of the 829 (100%) new HIV cases, 290 (35.0%) were diagnosed in the condition of AIDS. Most of the population was male and aged between 15 and 34 years old. Oral candidiasis and weight loss greater than 10% were the main symptoms associated with AIDS. It was observed that people with lower schooling levels and older were more prone to late diagnoses. Conclusion: it is necessary to devise strategies that favor timely diagnosis in the municipality under study, particularly among the individuals aged over 45 years old and with lower schooling levels.

ABSTRACT Objectives: to identify the relationships between nursing diagnoses for people living with HIV from the NANDA-International terminologies and International Classification for Nursing Practice (ICNP®) and to validate the equivalent meanings for diagnoses between language systems. Method: cross-sectional study, conducted in a reference hospital in northeastern Brazil, consisting of the following stages: 1) Identification of clinical findings through interviews and physical examinations with people living with HIV based on a validated script; 2) Structuring nursing diagnoses by means of Risner's clinical judgment; 3) Cross-mapping of nursing diagnosis statements with NANDA-I and ICNP® ; 4) Two rounds of Content validation using the Delphi technique with specialist nurses, for diagnoses with equivalent meanings between the systems. Data collection took place from August to November 2018. Results: in the preparation and identification of diagnoses, 135 nursing diagnoses were obtained, of which 62% (n=84) are included in the terminology of the ICNP® and 38% (n=51), from NANDA-International. For 81% (n=68) of the nursing diagnoses from the ICNP®, the absence of direct mapping in NANDA-international was identified, with 19% (n=16). The study showed that 47 diagnoses presented equivalent meanings. Conclusion: both systems enable the identification of nursing diagnoses accurately and have the ability to assist in the development of an individualized care plan for people living with HIV.
How perspective-taking underlies creative thinking and the socio-emotional competency in trainings of drama pedagogy
Authors: CELUME Macarena-Paz , ZENASNI Franck
Published: May 2022

Abstract Policy-makers and scholars agree that creativity and socio-emotional competencies can be taught, learned, and enhanced through creative arts like theatre. Nevertheless, few authors have studied the processes underlying both constructs in artistic education, which would permit to understand how children develop them and re-create adapted methodologies. Thus, we proposed to observe a drama pedagogy training for elementary school children, evaluating their creative thinking and theory-of-mind. To understand perspective-thinking as a process underlying creative thinking and theory-of-mind in the context of drama pedagogy training. Quasi-experimental pre-post-test design. Standardized tests analysis, plus thematic analysis from observation of 240 minutes recording of drama pedagogy training. Higher increase in creative thinking with a strong effect of drama pedagogy training on divergent thinking. Thematic analyses showed that drama pedagogy training activities focus mainly on socio-emotional competency (linked to theory-of-mind). Perspective-taking appears as an underlying process that explains both creative thinking and the development of socio-emotional competencies by permitting the child to see from another person’s perspective, providing several ideas-solutions for a problem (creative thinking), as well as understanding other people’s emotions and motivations (theory-of-mind).

Authors: SANTOS Jean Jesus , CERQUEIRA-SANTOS Elder
Published: May 2022

Abstract Discrimination against sexual and gender minorities is a persistent problem in several contexts. This article sought to investigate prejudice against sexual and gender diversity and beliefs about sex education among students of licenciatura (Brazilian term for a bachelor of education degree with a specialization) courses from different areas, and whether there are differences in the manifestation of these attitudes and beliefs between freshmen and seniors. Five hundred eighty university students participated in this study and the data was collected through scales to measure sexual and gender prejudice and beliefs about sex education, and through a sociodemographic characterization form. The results showed that prejudice and belief indices varied by area of study and differences were observed in the mean values of beliefs, but not in those of prejudice, between freshmen and seniors. The importance of more investments is emphasized so that undergraduate students present lower levels of this type of prejudice when completing their respective courses.
A voz das mentes famintas: a relevância de Danilo Dolci para a Psicologia Cultural da Educação
Authors: TATEO Luca
Published: May 2022

Resumo Danilo Dolci (1924-1997) foi um intelectual italiano, ativista social, sociólogo, educador popular e poeta, que passou a maior parte de sua vida nas áreas rurais da Sicília, tentando desenvolver uma visão progressista da educação como parte da emancipação da população da pobreza e do crime organizado. O cerne da pedagogia de Dolci era a ideia do cidadão como aprendiz e do aprendiz como cidadão. O ideal de educação promovido, também se referindo a Freire e Gandhi, era o de “cidadão do mundo”, capaz de superar uma atitude colonialista e opressora. Ao contrário, o que o sujeito é se origina nas raízes culturais e o torna capaz de reconhecer que ele é igual às outras pessoas no mundo. Para desenvolver seu ideal pedagógico, Dolci apostou na estética e na práxis, reconhecendo o valor do ser humano como parte da natureza. Finalmente, discute-se neste trabalho como as visões de Dolci sobre a educação podem fornecer novas perspectivas úteis para o desenvolvimento da psicologia cultural da educação.

Published: May 2022

Abstract Background Kidney disease is a rare manifestation of ankylosing spondylitis (AS) and its pathological alterations remain poorly described. The aim of this study was to investigate the clinical presentation and pathological alterations on kidney biopsy of AS patients and review and discuss the current literature on the issue. Methods: We retrospectively studied the clinical presentation and kidney pathological alterations of 15 Caucasian AS patients submitted to kidney biopsy between October 1985 and March 2021. Results: Patients were predominantly male (66.7%) with median age at the time of kideney biopsy of 47 years [IQR 34 - 62]. Median serum creatinine at presentation was 1.3 mg/dL [IQR 0.9 - 3] and most patients also had either proteinuria (85.7%) and/or hematuria (42.8%). The most common indication for kidney biopsy was nephrotic syndrome (33.3%), followed by acute or rapidly progressive kidney injury (20%) and chronic kidney disease of unknown etiology (20%). Chronic interstitial nephritis (CIN) (n=3) and AA amyloidosis (n=3) were the most common diagnosis. Others included IgA nephropathy (IgAN) (n=2), focal segmental glomerulosclerosis (n=2), membranous nephropathy (n=1), and immune complex-mediated membranoproliferative glomerulonephritis (IC-MPGN)(n=1). Conclusions: We present one of the largest series of biopsy-proven kidney disease in Caucasian AS patients. We found a lower prevalence of IgAN than previously reported in Asian cohorts. We found a higher prevalence of CIN and a lower prevalence of AA amyloidosis than that described in previous series of Caucasian patients. We also present the first case of AS-associated IC-MPGN.
Domínios armados e seus governos criminais - uma abordagem não fantasmagórica do “crime organizado”
Authors: Muniz Jacqueline de Oliveira , Dias Camila Nunes
Published: May 2022

RESUMO Busca-se contribuir para a compreensão das dinâmicas sociais, econômicas e políticas onde se estabelecem domínios armados com suas ambições de hegemonia sobre território e população e de monopólio de mercados ilegais. Parte-se das práticas de governança criminal do PCC em São Paulo e das milícias no Rio de Janeiro como ilustrações de exercício de governos criminais, explorando suas similaridades e diferenças. Propõe-se uma grade conceitual-analítica a partir de alguns elementos centrais como as múltiplas relações com diversos atores estatais, a complexa inserção comunitária e a diversificação criminal e regulação de mercados (i)legais. A abordagem da governança criminal coloca-se como alternativa às narrativas do “crime organizado”, substituindo noções teórico-abstratas por concepções teóricas-conceituais construídas a partir da observação empírica dos efeitos produzidos nos territórios sob domínio armado.
São Paulo, cem anos de máquina de crescimento urbano
Authors: Fix Mariana , Arantes Pedro Fiori
Published: May 2022

RESUMO Este artigo atravessa diferentes camadas históricas na metrópole paulistana, recolhendo pistas sobre operações imobiliárias de grande envergadura decisivas para o padrão de acumulação e segregação socioespacial em São Paulo no último século. O primeiro ato, nosso ponto de partida, é a operação imobiliária realizada a partir de 1910 pelo capital financeiro internacional em associação com agentes públicos e privados locais, em terras que correspondiam a mais de um terço da área urbana do município, sob liderança da Companhia City. O segundo ato, lida com os primórdios da articulação mais recente por trás da produção de um skyline que mimetiza aquele das chamadas cidades globais, nas margens do Rio Pinheiros. Entre eles, outra operação com terras que marcaria a história da cidade, com a captura de 21 mil hectares de áreas lindeiras ao Rio Pinheiros, obtidas com a canalização e retificação do rio, e drenagem de suas margens. A sucessão desses arranjos e coalizões que discutiremos não é linear nem indica necessariamente progresso, menos ainda desenvolvimento, mas sim estratégias de cada momento da máquina imobiliária de crescimento.
Convergências: pensar ensino e desigualdade com Scheffler, Patto, Bourdieu e Passeron
Authors: Silva Juliana de Souza , Silva Katiene Nogueira da , Cândido Renata Marcílio
Published: May 2022

RESUMO Nosso texto, assim como todos os que compõem a iniciativa deste dossiê, é o resultado dos esforços de evidenciar os livros e autores que se tornaram “clássicos” para cada uma de nós. Assim, os autores aqui em pauta foram escolhidos por serem leituras estruturantes da forma como pensamos e concebemos o mundo e a área à qual decidimos dedicar nossos esforços de pesquisa e de reflexão. Desse modo, neste artigo, retomamos as reflexões propostas por Maria Helena Souza Patto e Pierre Bourdieu e Jean-Claude Passeron sobre a desigualdade escolar, e Israel Scheffler sobre o discurso pedagógico que forja certas compreensões sobre ela. No momento contemporâneo, no qual a emergência de uma pandemia e seu consequente isolamento social impõem que a escolarização, para que continue ocorrendo, reinvente suas práticas, seus tempos e seus espaços, modificando a relação pedagógica, o acesso à tecnologia, o capital cultural herdado e a escolarização dos pais mostram-se como trunfos para o sucesso escolar. Nesse âmbito, retomar as contribuições de tais autores mostra-se um exercício potente de reflexão.
Ciência, evolução e educação em Herbert Spencer
Authors: Gatti Junior Décio , Santos Leonardo Batista dos
Published: May 2022

RESUMO As ideias do britânico Herbert Spencer (1820 a 1903) abrangeram diferentes áreas do conhecimento e, em sua época e para além dela, influenciaram discursos políticos reformistas pelo mundo, a saber: importância da ciência e de seu ensino nas escolas; contrariedade da interferência do estado na vida dos indivíduos; otimismo em relação ao progresso; seleção por competência; teoria evolucionista da sociedade. Sobre a educação advogou a existência de uma hierarquia de atividades: 1ª) conservação própria; 2ª) necessárias à conservação própria; 3ª) disciplina dos filhos; 4ª) procedimentos sociais e relações políticas; 5ª) restante da vida (gostos e sentimentos). Consideramos que a compreensão das ideias de Spencer favorece o entendimento do mundo histórico desde o final do século XIX até primeiras décadas do século XX, mas também permite refletir sobre questões importantes da atualidade.
O que significa descaracterizar barragens de rejeitos de mineração? Uma revisão sistemática da literatura
Authors: Massignan Rafaela Shinobe , Sánchez Luis Enrique
Published: May 2022

RESUMO Nova legislação que determina a descaracterização de barragens de rejeitos de mineração motivou esta revisão de métodos e técnicas de descaracterização e seus impactos ambientais. Foram identificados 105 artigos, publicados desde 1983, que descrevem soluções ou discutem desafios ao fechamento de barragens, quanto à estabilidade geotécnica e geoquímica, revegetação ou reutilização dos rejeitos, usualmente almejando a integração segura da barragem ao entorno. Apenas seis artigos abordam impactos ambientais das obras de descaracterização — como aumento do tráfego rodoviário —– e riscos associados à fitorremediação — particularmente a transferência de metais à cadeia alimentar. O assunto é pouco explorado na literatura internacional. Não há entendimento compartilhado sobre o significado de descaracterização, fechamento e termos relacionados. A experiência brasileira que resultará do atendimento à legislação, se devidamente analisada e documentada, contribuirá para o avanço do conhecimento e das técnicas de fechamento de barragens de rejeito.
Avaliação da degradação da qualidade da água do reservatório Carlos Botelho em Itirapina, São Paulo, Brasil, por meio de imagens do satélite Sentinel 2
Authors: Pompêo Marcelo , Moschini-Carlos Viviane
Published: May 2022

RESUMO Este estudo avaliou a qualidade da água do reservatório Carlos Botelho, SP, Brasil, empregando a base de dados da Companhia Ambiental do Estado de São Paulo para os anos de 2017 a 2019. Foram utilizadas as concentrações de clorofila a e o número de células de cianobactérias, relacionando-os com o algoritmo de processamento de imagens da Agência Espacial Europeia. Foram utilizadas imagens dos satélites Sentinel 2, com resolução espacial de 10 m e correção atmosférica Case 2 Regional Coast Color. Os dados de clorofila a da Companhia Ambiental do Estado de São Paulo e os estimados pelo algoritmo apresentaram alta correlação (R²=0,6052, RNMSE=27%, n=8) e também se relacionaram estatisticamente com o número de células de cianobactérias, o que permitiu estimar o número de células de cianobactérias nas imagens S2, por meio das concentrações de clorofila. Com base nas estimativas, o reservatório Carlos Botelho apresentou padrão eutrófico em praticamente o ano de 2020; os dados sugerem a presença e substancial predomínio de cianobactérias em toda massa de água e durante todo 2020 (da ordem de 10.000 a 20.000 células.mL); na sua água já foi constatada a presença de cianotoxinas potencialmente tóxicas; o reservatório possui uma praia pública, para recreação de contato primário; e tem no entorno condomínios com casas, clubes e chácaras. Este conjunto de características deve servir de alerta às autoridades locais, pois há necessidade para se discutir o programa de monitoramento ora em curso, com indicação da redução do monitoramento para no mínimo mensal e avaliações complementares, para verificação periódica da presença de cianotoxinas.
Interferência da ocupação urbana na distribuição de poluentes orgânicos persistentes em manguezal

Published: May 2022

RESUMO Áreas de mangue estão sujeitas a pressões antrópicas, ecossistema deposicional, e seus sedimentos contêm registros da história ambiental. Recentemente, foi criada uma Área de Preservação Ambiental na região de manguezais de São Gonçalo (Área de Preservação Ambiental de Itaoca). Esse local recebeu lixo doméstico ao longo de 28 anos. O perfil sedimentar determinou a geocronologia e quantificou os poluentes orgânicos persistentes, como hidrocarbonetos policíclicos aromáticos, bifenilas policloradas e pesticidas organoclorados. Os hidrocarbonetos policíclicos aromáticos apresentaram origem pirogênica com concentrações moderadas, exceto para o dibenzo [a,h] antraceno, um composto carcinogênico que excedeu o nível de efeito limítrofe. O registro sedimentar correspondente ao período anterior ao lixão sugeriu que os hidrocarbonetos policíclicos aromáticos estavam ligados à queima de madeira por olarias. O perileno foi um bom marcador para a redução da biomassa vegetal, sugerindo associação com a supressão de manguezais durante a ocupação. No período que antecede ao lixão, antes de 1976, a contaminação do sedimento por pesticidas organoclorados, como [2,2-bis (p-clorofenil) −1,1dicloroetileno] (metabólito primário do [1,1,1-tricloro-2,2-bis (p-clorofenil) etano]), foi vinculada a campanhas de saúde pública no combate ao mosquito da malária, ultrapassando os valores de nível de efeito limítrofe. No período de atividade do lixão, o aumento dos valores de [2,2-bis (p-clorofenil) −1,1dicloroetileno] coincidiu com o banimento do [1,1,1-tricloro-2,2-bis (p-clorofenil) etano], sugerindo seu descarte irregular. As bifenilas policloradas estavam abaixo das concentrações de nível de efeito limítrofe, mas semelhantes aos encontrados em lixões industriais em outros países. Os poluentes orgânicos persistentes mostraram-se eficientes marcadores antrópicos de ocupação urbana e contaminação acarretada pelo lixão. Por estar localizado em área de proteção ambiental, é necessária a retomada imediata do processo de remediação para interromper o processo de contaminação da Área de Preservação Ambiental em questão.

RESUMO A investigação de novas formas farmacêuticas para o tratamento de queimaduras, representa um importante avanço tecnológico na área de engenharia de tecidos. Nesse contexto, os hidrogéis à base de poli(álcool vinílico)(PVA) e quitosana(CS) funcionalizados com o óleo essencial de melaleuca surgem como excipientes promissores para uso como curativos, buscando através de um efeito sinérgico obter biomateriais com amplos espectros de ação biológica possível de acelerar e ser eficiente no reparo e cicatrização de tecidos lesionados como queimaduras. Para tanto, a presente pesquisa teve como objetivo a produção e caracterização de hidrogéis PVA/CS nas proporções 1:1 e 1:2 (m/v), respectivamente, funcionalizadas com 3% (v/v) do óleo de melaleuca (OM) pelo método casting, visando a aplicação como curativos. Os hidrogéis funcionalizados foram analisados qualitativamente por inspeção visual e analisados por ensaios de intumescimento e molhabilidade por ângulo de contato assim como caracterizados por microscopia eletrônica de varredura (MEV) e difratometria de raios X (DRX). Mediante a inspeção visual, a maioria dos hidrogéis apresentaram-se translúcidos, exceto o hidrogel PVA+3%OM que teve excelente transparência ótica. No geral, os hidrogéis apresentaram caráter superhidrofílico e bom grau de intumescimento na presença dos fluidos, água destilada e PBS, indicando que esses hidrogéis funcionalizados com óleo de melaleuca mostram-se promissores para aplicação como curativos na regeneração de tecidos lesionados.
Numerical study and seismic design of corroded circular RC columns strengthened by C-FRCM
Authors: Feng Ran , Li Yanwen , Zhu Ji-Hua
Published: May 2022

This study aims to numerically investigate the behaviour of corroded circular reinforced concrete (RC) columns strengthened by carbon-fabric-reinforced cementitious matrix (C-FRCM) composites. Three-dimensional finite element (FE) models of the corroded circular RC columns with and without strengthening were set up and validated against previous experimental results. Based on the validated FE models, the parametric studies were carried out to investigate the effects of axial compression ratio, degree of corrosion and layer of carbon fabrics on the behaviour of corroded RC columns under cyclic loading. It shows that the lateral load resistance increased when the axial compression ratio ranged from 0.3 to 0.4, but decreased when the axial compression ratio ranged from 0.4 to 0.6; also the ductility of the corroded RC columns reduced with increasing axial compression ratio. The ultimate capacity of corroded RC columns decreased gradually with the increasing degree of corrosion. Based on the results of parametric studies, equations were developed to estimate the ultimate capacity and displacement of the corroded RC columns repaired by the C-FRCM. The proposed equations can well estimate the ultimate lateral load resisting capacity and ultimate displacement of the corroded circular RC columns strengthened by C-FRCM.
A Scoping Review of Learners' Perceptions on What Influences Teachers' Approaches to Teaching Comprehensive Sexuality Education in South African Schools
Authors: Pillay Jace
Published: May 2022

Recent arguments regarding the South African comprehensive sexuality education (CSE) curriculum indicate that the existing programme neglects to incorporate factors that influence the behaviour of school learners in South Africa such as learners' and teachers' perceptions of cultural, social, and gender norms. Based on a literature search, it is evident that there is a paucity of research that reflects the voices of learners regarding their experience of how the CSE subject is taught as compared to what they want to learn. Therefore, this article aimed to conduct a scoping review to map learners' perceptions of what influences their teachers' approach to teaching CSE subject matter in South Africa. The Cochrane, EBSCOhost, Scopus, ProQuest, JSTOR, and Google Scholar databases were searched for studies (a) published from January 2010 till May 2021, (b) with an explicit focus on learner feedback on their perceptions of influences to teachers teaching CSE, (c) that were qualitative studies, and (d) were published in English in peer-reviewed journals. Four studies were identified that reported on data collected from learners aged 14-18 years using in-depth interviews (N = 1), focus group discussions (N = 2), and an ethnographic study (N = 1). A qualitative analysis of the findings identified three major themes: (1) an inherent bias towards heterosexuality as normal and natural, (2) the belief that learners need to be taught to uphold culturally dictated normative gender roles, and (3) an avoidance of subject matter relating to the LGBTQI+ community, influenced by beliefs that limited interactions would lead to limited gender and sexual fluidity. Findings conclude that transformative communication needs to take place to update the curriculum to create a space for all learners to learn about healthy life choices.
I'm a "Savage": Exploring Megan Thee Stallion's Use of the Politics of Articulation to Subvert the Androcentric Discourses of Women in Hip Hop Culture
Authors: Rajah Azra
Published: May 2022

Hip hop music is understood to be a tool that promotes equality for a group of people who were previously marginalised and discriminated against. However, misogyny and sexual exploitation of women remain dominant characteristics of hip hop culture. When exploring research on women in hip hop culture, scholars tend to focus on misogyny and the hypersexualising of women, thus disregarding the fact that women can express and enjoy their sexuality purely because it is their prerogative to do so. This article highlights how Fairclough's (1995) model of critical discourse analysis can be used as a lens and tool to introduce alternative perspectives on these discourses and ideologies. Specifically, this research interrogates how Megan Thee Stallion applies the politics of articulation through her rap lyrics to subvert the androcentric discourses of hip hop culture, which objectify and sexually exploit women-specifically, Black women who have been historically subjected to the politics of respectability that positions Black women in inferior position to White women.
Rethinking Constructions of Difference: Lessons from Lesotho's Chief Mohlomi's Activism against the Gendering of Witchcraft
Authors: Mofuoa Khali , Khau Mathabo
Published: May 2022

Discrimination according to gender has been in practice in communities globally since time immemorial. This discrimination has infiltrated all spheres of life including the naming, shaming, blaming, and persecution of deviant people as witches. The phenomenon of witchcraft has historically been negatively skewed towards women, with women's gender and sexual diversity being used against them in accusations of witchcraft. In some modern-day African communities, gender and sexual diversity are still regarded as witchcraft or a result of bewitching. While activism against witchcraft has gathered momentum across Africa, it is worth noting that in Lesotho, such activism began in the precolonial era through the leadership of Chief Mohlomi. In this paper, we explore the understandings and experiences of constructions of difference as witchcraft among the Basotho of Lesotho. Using a qualitative research approach, we employed life-history narratives and focus group discussions to generate data with 10 Basotho men and women aged 70-93 years. We used sankofa theory to frame our analysis of the data, which was done thematically. Drawing on the ethnographic data, we discuss lessons regarding constructions of difference as witchcraft, and Chief Mohlomi's (1720-1815) activism against the discrimination of those labelled as witches. The findings reveal that divergent gender and sexual characteristics and identities were used in labelling certain individuals as witches and unexplainable phenomena as witchcraft. However, the findings also show that Chief Mohlomi set in motion a spirited activism against the persecution of divergent people through his teachings, which led to transformed views on gender and sexual diversity among the Basotho. These findings have implications for an education that embraces diversity in all spheres of life to promote inclusive and sustainable communities.
Understanding crime using GIS and the context of COVID-19: the case of Saldanha Bay Municipality
Authors: Henrico I , Mayoyo N , Mtshawu B
Published: May 2022

South Africa faces high levels of crime. The Saldanha Bay Municipality, the setting of this study, is laden with poverty, unemployment and gangsterism that deprive quality of life and contribute to social ills. While crime management and prevention strategies require information regarding crime trends, this information for the Saldanha Bay Municipality area is limited. Hence, the study aimed to illustrate the spatial distribution and trends of crime in the Saldanha Bay Municipality, focusing on the period January 2017 to June 2020, and to indicate the recent impact of COVID-19 on these crime trends. The results of the study are presented by means of graphs and tables, and hotspot mapping was done using the ArcGIS Getis-Ord Gi* statistics tool. These results indicate that crime has increased over the past three years and that criminal activities are linked to urban hubs where most people stay and work. In terms of the effect of the COVID-19 pandemic and the lockdown regulations on crime, it is interesting to note the variations in crime rates during the first 3 months of lockdown (from April 2020 to June 2020) when compared to the rest of the period under investigation. Amongst the five towns investigated, the town of Vredenburg which has the highest population total and was ranked highest in terms of crime rates prior to the lockdown, moved from first to third, behind Langebaan and St Helena Bay. Similarly, Saldanha Bay with the second highest population total moved down to fourth. Hopefield was still the town with the lowest mean crime rate.
The Invisibilities of an Afrofuturistic utopia - the erasure of Black queer bodies in Black Panther
Authors: Mntungwa Melusi
Published: May 2022

Although Black Panther (Coogler 2018) has been revered as a cultural text that presents an Afrofuturistic way Black people could imagine and see themselves, it is not void of societal prejudices. Such prejudices include the treatment of Black queer people in the film's narrative. Much like the society in which Black queer people find themselves, the kingdom of Wakanda in Black Panther fails to acknowledge and depict their humanity and existence. As such, this article interrogates Black Panther's erasure of Black queer individuals from its plot and narrative. It explores the complicated position that Black queer individuals find themselves in, in a society where they are in constant danger of violent erasure from the public discourse. Drawing on a close reading of the Black Panther's narrative, this article argues that, as a cultural text, Black Panther fails to employ ubuntu in its treatment of all identities. At the core of my reading of Black Panther is a critique of how the Afrofuturistic kingdom of Wakanda as a symbol of affirmative Black identity mirrors the same prejudices of present society by not recognising the existence of Black queer identities, erasing them from reality. I ultimately argue that Black Panther's potential to be reflective and inclusive is not optimally reached.
