Authors: Gusango Emmanuel , Maani John , Ssetumba John 
Published: May 2021

Purpose: The purpose of this study was to explore the ICT and reflective practice integration in teacher preparation at Primary Teachers Colleges and to establish whether these practices were among the constructivist approaches being used to teach students.
Methodology: This phenomenological study explored the lived experiences of tutors and students in light of constructivists’ teaching. It involved 3 PTCs and 15 participants who were purposively sampled. This study used a qualitative research design. Data was gathered using in-depth multiple interviews and analyzed following Moustakas (1994) procedure.
Findings: Data analysis and results revealed that tutor‘s continue to rely on traditional approaches in both instruction and supervision of school practice. The colleges are in a nascent stage in the integration of ICT and reflective practice in education being accustomed to traditional instructional practices and lack of motivation and knowledge among tutors to adopt ICT in teaching.
Unique Contribution to Theory, Practice and Policy: This research study adds to the body of knowledge suggesting ways in which constructivists’ teaching supports teaching effectiveness and promotes students’ learning amplifying the need for ICT and reflective practice integration in instruction. The study recommends establishing and setting up Reflective Practice Laboratories in Primary Teachers Colleges for tutors and students induction on several constructivists’ practices that include systematic reflection, clinical supervision, use and integration of ICT and other interventions in a proper and professional setting

Published: May 2021

Wireless communication devices such as mobile phones play a vital role in our daily life. They need to cover an increasingly wide frequency band with low profile antennas. Electrically small antennas (ESAs) comply with these requirements. However, they are subject to gain-bandwidth limits when matched with passive matching networks. Non-Foster reactive elements have been proposed to bypass those restrictions. This paper addresses designing negative group delay NGD-based non-Foster networks to overcome stability problems when using Negative Impedance Converters (NICs) in order to realise on-Foster reactive circuits. The NGD network model was designed using open short stubs to achieve a non-Foster behaviour, and to act as a negative capacitor in the frequency range of interest. This technique of compensating the inherent loss of the proposed NGD network in the reflection mode was to realise a new structure of reactive non-Foster elements. It involves a negative resistance amplifier and a Lange coupler. The proposed technique is applicable to antenna matching where both transmit and received capabilities are required. It was simulated and the experimental results of the new NGD network circuit were introduced.
Arquitetura e efêmero: a festa como heterotopia na cidade de Brasília.

Published: May 2021

A pesquisa apresenta um estudo analítico-crítico das relações estabelecidas com o espaço urbano a partir da realização de festas e eventos no plano piloto, tendo como eixo norteador o conceito de heterotopia definido por Michael Foucault. O trabalho tem como objetivo investigar formas contemporâneas de se apropriar do espaço urbano do plano piloto levando em consideração que as escalas determinadas no projeto original eram favoráveis ao uso coletivo, entretanto muitos dos vazios urbanos instalados com em diversos setores vieram a se tornar ociosos. A pesquisa visou traçar uma reflexão alternativa à noção de funcionalidade dos espaços, contabilizando e observando fatores relacionados à eventos festivos através de mapeamentos que levantaram informações acerca de data, horário, turnos recorrentes, quem os produz, localização geográfica, espacialidade (se abertos ou fechados), acessibilidade e faixa etária. Inicialmente foi buscado na literatura embasamento que identificasse aspectos relevantes das festas e eventos para as culturas e para os espaços urbanos, em seguida foi dado início às pesquisas de campo onde foram feitas observações a respeito do espaço e realizados os registros fotográficos. Simultaneamente aconteciam o mapeamento virtual onde foram colhidas informações essenciais à análise quantitativa para preenchimento de tabela que ao final veio a se transformar no apêndice do trabalho. Durante o período de coleta de dados surgiu a necessidade de adaptar a pesquisa as condições externas que vieram a modificar todas as relações estabelecidas nos centros urbanos por questões sanitárias, logo modificaram-se as dinâmicas de eventos, e novasquestões a respeito do segmento vieram a aparecer. Estabelecidos dois recortes, o (pré pandemia e o de isolamento social) observou-se através dos dados gráficos levantados a ampla distribuição dos eventos no plano piloto, dando destaque à concentração de eventos no eixo central da cidade, em especial em áreas amplamente subutilizadas. Foi possível, também, constatar a flexibilidade e relevância do segmento ao se reinventar diante de medidas sociais restritivas, apesar de se sustentar englobando um grande número de pessoas.

A saúde mental tem alçado novos patamares na vida hodierna, de forma que os cuidadosdirecionados ao bem-estar psicológico revelam-se sob uma nova luz. Nesse contexto, adetecção de condições adversas é imprescindível para a devida intervenção construtiva ereparadora no âmbito da saúde psíquica. Ademais, a apreciação de variáveis individuaisinerentes ao ser é um ajuste necessário à devida análise dos riscos em saúde. Diante desta definição, os pesquisadores procuraram aliar o alicerce teórico referente ao Inventário de Maslach (uma ferramenta de rastreamento do burnout precipitado pelo estresse ocupacional) à escala DS14 (um instrumento psicométrico usado para diagnosticar a personalidade do tipo D, fator de risco para desfechos clínicos desfavoráveis, inclusive na seara psíquica). Para tanto, desenhou-se um estudo transversal analítico, de caráter quantitativo-qualitativo, mediante triangulação de métodos. Realizado em três fases distintas, o presente estudo foi iniciado por uma revisão bibliográfica, seguida por uma coleção de dados por via de formulário eletrônico, finalizando-se com um comparativo entre as hipóteses suscitadas e os resultados obtidos a partir dos formulários e da realização de um grupo focal para se obter a saturação teórica. Uma vez finalizadas as duas primeiras fases, constatou-se que 77% (n=114) dos sujeitos da amostra apresentam indícios de alto risco para o desenvolvimento da síndrome de burnout, a partir da patogênese clássica, iniciada pela exaustão emocional. Outrossim, 66,9% (n=99) dos sujeitos apresentam traços condizentes com a personalidade tipo D. Ademais, a realização do grupo focal foi impossibilitada devido a restrições metodológicas perante a pandemia do Sars-CoV-2 no território do Distrito Federal. Dessa forma, os pesquisadores concluíram que a correlação entre as manifestações da síndrome de burnout e o parâmetro psicométrico da personalidade tipo D não é suficientemente evidenciada, de tal forma que não é possível afirmar de maneira conclusiva acerca de uma associação entre essas duas variáveis distintas, postulando-se a necessidade de repetir as metodologias empregadas com o fito de consolidar os objetivos originalmente pretendidos.

IntroductionThis study is aimed to explore the effects of Adenosine A2a receptors (A2aR) on hypoxia-induced pulmonary hypertension (HPH) via mitochondrial ATP-sensitive potassium channels (MitoKATP) in vivo and in vitro.Material and methodsUsing wild-type (WT) and A2aR-deficient (A2aR-/-) mice; hypoxic pulmonary artery smooth muscle cells (PASMCs) were induced by a 24-hours hypoxia exposure. Mice and PASMCs were treated with the A2aR agonist CGS21680, MitoKATP blocker 5-hydroxydecanoic acid sodium salt (5HD), or MitoKATP agonist diazoxide. Mitochondrial morphology was observed by electron microscopy. The mitochondrial membrane potential (Δψm); invasive hemodynamic parameters; right ventricular (RV) hypertrophy index; pulmonary arterial remodeling index; proliferative and apoptotic indexes; protein expression levels of A2aR, Bax, Bcl-2, and Caspase-9; and release of cytochrome C from the mitochondria to the cytoplasm were measured.ResultsIn vitro, hypoxia induced the opening of MitoKATP. The up-regulation of A2aR reduced the opening of MitoKATP, and the blocking of MitoKATP or activating A2aR promoted mitochondria-dependent apoptosis of PASMCs. In vivo, compared with WT mice, A2aR-/- mice displayed increased RV systolic pressure, RV hypertrophy index, and pulmonary arterial remodeling index. The expression levels of Bax, cytochrome C, and Caspase-9 were higher and Bcl-2 expression was lower in A2aR-/- mice than in WT mice. CGS21680 could reverse hypoxia-induced hemodynamic changes, RV hypertrophy, and pulmonary arterial remodeling as well as abnormal proliferation and apoptosis resistance in WT mice with pulmonary hypertension (PH).ConclusionsA2aR induced the mitochondrial-dependent apoptosis pathway and inhibited PASMC proliferation by blocking MitoKATP, thereby inhibiting pulmonary vascular structural remodeling and reducing PH.

Published: May 2021

The intent of this study was to find out the influence of teacher attitude on effective implementation of inclusive education policy in public primary schools in Kitale Town, Kenya. The study found teacher attitude had a significant influence on the effective implementation of inclusive education policy. Inclusive education is a form of education wherein all students including special needs (SN) learners attend and are received by their neighbourhood schools in age-appropriate regular classes and are supported to learn to participate and contribute in all views of life at school. Neighbourhood public schools being at the heart of our communities are essential for the quality inclusive education system. The research design used for the study was descriptive. Interview schedules, questionnaires, and observation checklists were employed in data collection. The target population was 36 headteachers in the public primary schools in the town and 50 special needs teachers. The sample size was 76 respondents who were selected using purposive and simple random sampling. The validity of data collection tools was determined through pilot study and assistance from supervisors. Reliability was tested using the test-retest method, whereby a value of .92 was obtained. Hypotheses were examined using regression analysis at 0.05 level of significance. The study recommends that the TSC consider teachers handling special needs learners in inclusive scopes for special duty allowances that are being given to their counterparts working in special schools and the curriculum to be assessed to enhance effective implementation of inclusive education.

Published: May 2021

This study attempted to examine the relationship between economic factors and gender disparity in enrolment of students in mixed public day secondary schools in Kericho County, Kenya. Social Demand Theory guided the study. The study adopted a descriptive survey research design. The study targeted 124 public mixed day secondary schools. The target population consisted of 124 principals and 9,418 students. Sampling techniques applied included purposive and systematic random sampling techniques. A sample size of the principals was determined by applying Kerlinger (1986) 30% rule, whereas for the students Cochran formula was used. The sample size consisted of 38 principals and 384 students. Data for the study was collected by the use of questionnaires. The study revealed that there exists a statistically significant relationship between Economic Factors and Gender Disparity (r=0.768; p<0.05). From the findings, in connection with economic factors, it was established that child labour had the highest mean of 3.21 and therefore was the major factor related to gender disparity in enrollment. This was followed by parents' reluctance to pay fees due to the false notion of free education with a mean of 3.10. The study concluded that the government, through quality assurance and standards officers alongside local administration, should ensure that policies on child labour are well implemented. That child labour is not practised so that all school age going children irrespective of their gender attend school uninterrupted.
