Published: March 2021

Resumo: O presente artigo busca lidar com a conceituação teórica do que se configura como “presidencialismo de coalizão”. Através da apresentação da teoria das coalizões (coalition theories), argumenta-se que a discussão e o próprio entendimento sobre o presidencialismo de coalizão são apenas uma ramificação de uma longa literatura existente sobre as coalizões governamentais. Em vista disso, um dos objetivos do trabalho é mostrar que o presidencialismo de coalizão não é um fenômeno tipicamente brasileiro. Na verdade, existe uma longa tradição de governos de coalizão em outros países latino-americanos. Por fim, mesmo que já tenha sido extensivamente estudado, vê-se que ainda existe muito a ser pesquisado na temática dentre o presidencialismo de coalizão. Assim, explora-se o conceito de coalizões, colocando-o em perspectiva com o presidencialismo e, ao final, analisam-se os possíveis novos caminhos de pesquisa nessa temática.

Neste artigo utilizou–se um campo magnético da forma ℬ → = ℬ 1 [ cos ( ω t ) i ^ + sin ( ω t ) j ^ ] + ℬ 0 k ^ como ordem zero de uma expansão, advinda de um campo magnético parabólico, para descrever o movimento confinado de uma partícula eletricamente carregada sujeita a uma força de Lorentz, com uma dinâmica válida para uma região específica do espaço. As equações de movimento obtidas são não-lineares e uma solução particular pode ser extraída, na qual a partícula realiza um movimento periódico. Além disso, através das seções de Poincaré e expoentes de Lyapunov, constatamos que o sistema é caótico, e, portanto, admite deferentes forma de trajetórias quase fechadas obtidas variando–se levemente os parâmetros e condições iniciais, a partir de uma solução numérica.

Resumo O processamento de frutos ainda verdes para produção de farinhas pode ser considerado uma opção para minimizar as perdas pós-colheita e agregar valor ao produto. O objetivo do trabalho foi avaliar a composição físico-química e nutricional de farinhas de banana verde (FBV) com casca, obtidas a partir de diferentes variedades. Para a produção das farinhas, foram utilizadas: banana-prata, banana-da-terra e banana-maçã. A secagem foi realizada em estufa a 105 °C, por 12 horas. Foram realizadas análises de umidade, pH, cinzas, carboidratos, proteínas, lipídios, fibras e amido. Todas as farinhas produzidas apresentaram teor de umidade adequado. Quanto ao teor de fibras, todas as variedades apresentaram bons resultados, o que se deve ao fato de preservar a casca na sua produção, bem como um teor de amido elevado para banana-da-terra e banana-maçã, o que reforça a grande quantidade no fruto ainda verde. Todas as farinhas apresentaram um baixo valor calórico. Portanto, é viável a utilização da FBV com casca de todas as variedades estudadas, principalmente pelo teor de fibras, validando, assim, o presente trabalho. É possível destacar ainda a importância da produção de farinha de banana verde com casca, visando manter um maior número de nutrientes, por vezes encontrados na casca, bem como possibilitar o aproveitamento integral da banana.

Resumo O atual Plano Diretor Estratégico do Município de São Paulo (PDE-MSP) (Lei Municipal 16.050/2014) reformulou as bases jurídicas da Outorga Onerosa do Direito de Construir (OODC). O presente texto busca compreender como a implementação desse instrumento, visto como parte das “políticas do urbano” discutidas por Eduardo Marques (2018), impacta as operações de instituições governamentais do município paulistano que atuam: (i) nos processos de licenciamento urbanístico das edificações de empreendimentos imobiliários e (ii) no monitoramento dos processos de implementação da OODC. Discute-se também o Conselho Gestor do Fundo Municipal de Desenvolvimento Urbano (FUNDURB). Parte-se da hipótese que a implementação da OODC afeta e modifica as rotinas da administração pública. Para verificar tal hipótese examinam-se os procedimentos e instrumentos segundo metodologia neoinstitucionalista mencionada por Pierre Lascoumes e Patrick Le Galés (2012). Os dados e informações utilizados no trabalho foram obtidos em entrevistas com funcionários públicos, consultas a sites e análise de legislações da Prefeitura do Município de São Paulo (PMSP). As descrições e exames apresentados mostram o envolvimento da OODC em processos e relações rotineiras de gestão urbana cujos instrumentos e práticas burocráticas, operados no interior de estruturas institucionais e de procedimentos administrativos, medeiam as interações entre atores governamentais e não governamentais.

Significance Statement

Atypical hemolytic uremic syndrome (aHUS) is often related to complement dysregulation, but its pathophysiology remains unknown in at list 30% of patients. Anti-factor H autoantibodies of the IgG class are responsible for 10% of patients with aHUS; autoantibodies of IgM class have not been reported. The authors found anti-factor H IgM autoantibodies in seven of 186 patients with aHUS, with a frequency six-fold higher in patients with a history of hematopoietic stem cell transplantation. The purified IgM autoantibodies recognize the active site of the factor H molecule and inhibit its binding to C3b. These findings indicate that some forms of aHUS of unknown origin could be placed within the setting of autoimmune diseases, stemming from the presence of IgM autoantibodies specific for factor H’s active site.

Background

Atypical hemolytic uremic syndrome (aHUS), a severe thrombotic microangiopathy, is often related to complement dysregulation, but the pathomechanisms remain unknown in at least 30% of patients. Researchers have described autoantibodies to complement factor H of the IgG class in 10% of patients with aHUS but have not reported anti-factor H autoantibodies of the IgM class.

Methods

In 186 patients with thrombotic microangiopathy clinically presented as aHUS, we searched for anti-factor H autoantibodies of the IgM class and those of the IgG and IgA classes. We used immunochromatography to purify anti-factor H IgM autoantibodies and immunoenzymatic methods and a competition assay with mapping mAbs to characterize interaction with the target protein.

Results

We detected anti-factor H autoantibodies of the IgM class in seven of 186 (3.8%) patients with thrombotic microangiopathy presented as aHUS. No association was observed between anti-factor H IgM and homozygous deletions involving CFHR3-CFHR1. A significantly higher proportion of patients with bone marrow transplant–related thrombotic microangiopathy had anti-factor H IgM autoantibodies versus other patients with aHUS: three of 20 (15%) versus four of 166 (2.4%), respectively. The identified IgM autoantibodies recognize the SCR domain 19 of factor H molecule in all patients and interact with the factor H molecule, inhibiting its binding to C3b.

Conclusions

Detectable autoantibodies to factor H of the IgM class may be present in patients with aHUS, and their frequency is six-fold higher in thrombotic microangiopathy forms associated with bone marrow transplant. The autoantibody interaction with factor H’s active site may support an autoimmune mechanism in some cases previously considered to be of unknown origin.

Age-related changes of reactive agility in football
Authors: Horicka Pavol , Simonek Jaromir
Published: March 2021

The purpose of this investigation is to determine age dynamism of reactive agility in young football players, thus specifying the impact of sport training on the level of reactive agility of players. 112 young male football players playing for the football club in Nitra, Slovakia volunteered to participate in the study. Another goal was to clarify the age dynamics of performances in the monitored groups of football players and to find out the mutual relationship between the two types of agility. Trends in sport performance and relationship of both kinds of agility were observed in 6 teams of different age categories (U11 up to U16). In order to fulfil the aim of the research two different motor tests for running agility (Illinois agility test) and reactive agility (Fitro Agility Check) were selected. For the realization of Fitro Agility Check test, a computer with the necessary hardware and software, and measuring device Fitro Agility Check were used. To evaluate the relationship between the observed variables (Illinois vs FAC), we used Spearman's correlation coefficient rs (-1 ≤ rs ≤ 1) to perform correlation analysis in SSPS statistical software. We used a significance level of 0.01. The results of this study provide evidence of stabilization of performance with the growing age of players at the level of both types of agility and a dynamic increase, especially after the age of 13. Low values of correlation coefficients (from r = - 0.570 to 0.503) indicate indifferent determinants in running and reactive agility. Since low causal-consequential relationship between reactive and running agility was found in the observed football teams, there is a necessity in the sports training to differentiate between specific means for the development of the so-called pre-planned and reactive agility.

Published: March 2021

Optimization of training and minimization of injuries are topical for the physical performance of military personnel. Physical and psycho-emotional load, fatigue, sleep deprivation, and dietary limits can lead to the development of oxidative stress (OS) and injuries in specific military training. This study investigated markers of OS and muscle damage in military cadets after a 10-day-long intensive training course and a one-month-long recovery. The sample included 42 cadets (2 females and 40 males) aged from 22 till 34. Myoglobin, catalase activity (CAT), superoxide dismutase activity (SOD), and total antioxidants capacity (TAC) in plasma were measured. OS was assessed by the glutathione index. The results revealed an increasing level of myoglobin, increasing glutathione index, and no changes in CAT, SOD, and TAC during the intensive training course. After the one-month-long recovery, myoglobin was back to normal, the activity of CAT and TAC was higher than before and after the training course, while SOD did not change after the recovery. The glutathione index decreased after the one-month-long recovery, but it was not reached the initial level before the intensive training. In sum, the observed grade of OS positively affected the capacity of the antioxidative system with some sign of a need for a longer rest.

Authors: DALMAZ Aslıhan , DURMUŞ Sefa , DULGER Gorkem , DÜLGER Başaran
Published: March 2021

In this work, firstly, CeO2 nanoparticles, which can be used as catalysts in many reactions, were synthesized by preparing aqueous solution of cerium(III) nitrate hexahydrate in basic medium. In the second step, the synthesis of dimeric thio Schiff bases was carried out using two different methods. Effect of catalyst on some parameters such as reaction time and yield of product were investigated. The antimicrobial activities of the ligands have been screened in vitro against the organisms Acinetobacter baumannii, Escherichia coli, Klebsiella pneumoniae (Gram negative bacteria), Staphylococcus aureus, Staphylococcus epidermidis, Enterococcus faecalis, Bacillus cereus (Gram positive bacteria) and Candida albicans, C. tropicalis, C. guilliermondii, C. glabrata by Disc Diffusion and Microdilution methods. At the same time, antimicrobial activities of ligands were compared to standard antibiotics (Cefotaxime, Amoxicillin/clavulanic acid, Posacanazole, Nystatin and Gentamicin). Generally, the results obtained in this research showed that all tested ligands exhibited more effect towards Gram positive bacteria and Candida species as compared to standard antibiotics.
An experimental and comparative study of the self-loosening of bolted-joints under cyclic transverse loading
Authors: İNCE Umut , GÜDEN Mustafa
Published: March 2021

The capabilities of analytic models in predicting the experimental critical displacements of the self-loosening of bolted-joints were investigated experimentally and numerically. The experimental loosening rates were determined in a Junker test bench at a constant transverse displacement amplitude (0.45 mm) and under varying initial clamp force and clamp length and controlled bearing and thread friction coefficients. The analytic critical displacements were then calculated using experimental parameters. In addition, a three-dimensional accompanying finite element (FE) model was developed in order to calculate the ratio of spring constants engaging the thread to spring. The results showed relatively low capabilities of present analytic model in the prediction of the critical displacements of the self-loosening of bolted-joints. The efforts to modify the nut reaction moment and the inclination compliance of bolt head portion in the investigated equations however resulted moderate increase in the correct predictions. On the other side, the use of the reaction moment determined by FE model increased the correct prediction from 58.3 to 73.4%. The accuracy of the equations was further increased by the use of an appropriate kw value, but the increase in this case was only ~4%.

Authors: SEZER Senem , ÖZVEREN Uğur
Published: March 2021

Considering economic and environmental issues, boosting renewable energy source is the main subject to fulfill energy demand in these days. Biomass as natural and abundant energy source can be typically used to produce electricity, fuels and heat applying thermochemical conversion processes such as combustion, pyrolysis or gasification. Biomass combustion is the most common process to produce electricity and useful heat in Turkey and all over the world. The aim of this study is to investigate the considerable influence of heating rates on combustion characteristics and kinetics employing a new developed non-linear kinetic model for hazelnut husk samples through thermogravimetric analysis. Furthermore, this work comprehensively assesses the variations in the reactivity of hazelnut husk combustion, expressed from thermogravimetric curves. The non-linear kinetic model developed in this study integrates the various kinetic pathway to estimate the major controlling parameter of combustion reactivity, its activation energy, pre-exponential factor and reaction order. According to comparison of results from the non-linear kinetic model for volatile combustion and fixed carbon combustion, correlation coefficients (R2) for both models are higher than 0.9985. These results proved the non-linear regression model for kinetic pathways in combustion reactivity worked properly to estimate thermal decomposition behavior.

Covalent Coupling Protein to Carboxylated Microparticles via EDAC v1
Authors: Schackart Kenneth , Kaarj Kattika
Published: March 2021

This protocol details how to covalently couple proteins to carboxylated polystyrene particles (microspheres) via EDAC. In this reaction, 1-Ethyl-3-(3-dimethylaminopropyl)carbodiimide (EDAC) serves as an agent for covalently coupling protein (e.g. peptides, IgG, etc.) to carboxyl-modified particles by forming an amide bond. Various 2-(N-morpholino)ethanesulfonic (MES) acid buffers are used to maintain the appropriate pH ranges. Glycine is used as a quencher to cease the reaction. Bovine serum albumin (BSA) is used as a blocking agent, to prevent non-specific interactions with and between particles (e.g. hydrophobic interactions). This protocol's development was guided by the information contained in Bangs Laboraties Inc. Tech Note 205, Covalent Coupling. This file is attached as a PDF.
Development of simplified mathematical model of P-88 recovery boiler for operating modes at loads near the nominal
Authors: Shelygin B.L. , Pankov S.A. , Ledukhovsky G.V.
Published: March 2021

To improve the design of the elements of combined-cycle plants, and their structural and mode optimization, mathematical models are required. These models show energy efficiency indicators of the equipment under changing operating conditions. Modeling of recovery boilers is traditionally carried out with the application of specialized software systems that implement submodels of thermal-hydraulic calculations of the elements of the boiler water-steam and gas paths. This approach makes it difficult to solve practical tasks, since it requires licensed software and appropriate qualifications of an engineer. The current direction of solving this problem is statistical processing of the results of calculation data obtained with the application of specialized software systems, and development of a simplified mathematical model in the form of regression dependencies of boiler performance on variable parameters. In this study, the problem is solved in relation to the P-88 boiler of the combined-cycle plant-325 power unit in the load range near the nominal one. The initial mathematical model is developed with the application of the software package “TRAKT” designed for verification and engineering design of boilers. The simplified mathematical model is based on the methods of regression analysis of statistical data. The accuracy of the model is estimated based on the operational data of the combined-cycle plant -325 power unit. The authors have developed the mathematical model of the P-88 recovery boiler, which allows to determine the main performance indicators of the boiler when the electric power of the gas turbine and the outdoor air temperature are changing at the loads near the nominal value. The performance indicators are determined without application of specialized software for design calculation of the boiler. The accuracy of the initial mathematical model implemented in the software package “TRACT” is characterized by deviation of the calculation results data from the operational data in the corresponding modes of no more than 2 %. The additional uncertainty value introduced into the calculation results data does not exceed 1,5 % when we transfer from the initial mathematical model to the simplified one. The resulting mathematical description will allow solving the problems of mode optimization and evaluating the efficiency of the recovery boiler and the power unit under changing operating conditions.

Using Secondary Health Data in Research
Authors: Al Omari Mohammed
Published: March 2021

The use of data in medical research that was originally collected for different purposes, known as secondary data, is an effective way to conduct reliable and cost-effective studies so as to progress knowledge in medicine. A number of serious practical, ethical and legal issues and concerns about this process exist, however. Ensuring a high level of data quality is imperative to produce reliable results, and researchers may face accessibility problems. Projects designed to alleviate these issues are underway, however, lowering the cost and increasing the access to secondary data even further. Although secondary data is de-identified to protect the confidentiality, ethical problems of individual rights versus the benefit of society persist, leading some to call for a new ‘macroethics’ surrounding data use. Legislation to this end has been introduced in many countries, but issues relating to the exemptions it offers and its interpretability remain. To ensure that the use of secondary data in medical research can continue to accelerate the pace of development in medicine, a global effort involving technological and ethical standardization needs to be developed.
Effect of Sub-Contractor Selection on Construction Project Success in Turkey
Authors: KARAMAN Ali Erkan , SANDAL Koray
Published: March 2021

The construction industry leads the national economy in developing countries. It involves industrial requirements, such as developing technologies, related expertise, demand variability, high production speed and progress. Firms in the industry use subcontractors to produce fast, effective solutions. Therefore, projects’ success varies depending on subcontractors’ rather than general contractors’ performance. This study aimed to develop a model of selection criteria for subcontractors and measure their impact on project success. Construction firms using subcontractors were chosen as the target group. Data on the selection of subcontractors from 93 construction firms that employ subcontractors in their projects were collected through a survey. The impact of the subcontracting selection factor on projects’ overall performance was presented with five hypotheses and modeled using a structural equation model. The weight of each selection factor in the subcontracting selection and the impact on the overall project were designated in the model by determining the standardized regression weights (β). Four hypotheses were accepted and one rejected. This study may contribute to the prequalification conditions in the process of selecting subcontractors in the future.

Роль иракской нефти в стратегии США
Authors: Дажанаби Якуб Сабих Хасан , Козуб Екатерина Алексеевна
Published: March 2021

В статье рассматривается роль нефтяного фактора в присутствии сил Соединѐнных Штатов Америки в Ираке в исторической ретроперспективе. Авторы анализируют геостратегические, экономические и политические интересы США в регионе Персидского залива, в частности, в Ираке. Делается вывод, что оккупация Ирака силами Соединѐнных Штатов была направлена не на борьбу с терроризмом, а прежде всего преследовала цель получить контроль над разработкой богатых энергоресурсов Ирака, что также дало возможность установить цены на нефть. Кроме того, в интересах американского правительства было не допустить доминирование других международных акторов в данном регионе и избежать конкуренции в борьбе за энергоресурсы.

Authors: Ивашкин Михаил Александрович
Published: March 2021

Статья посвящена анализу взаимоотношений Франции с государствами ближневосточного региона через призму внешнеполитического курса Николя Саркози и Франсуа Олланда. Ближневосточное направление внешней политики является традиционным для республики, в связи с чем входит в сферу внешнеполитических приоритетов лидеров государства. Цель данной работы заключается в сравнении ближневосточной политики Франции при президентстве Н. Саркози с курсом Ф. Олланда. Для достижения обозначенной цели требуется решить ряд задач: исследовать реализацию внешнеполитического курса президентов в отношении стран Ближнего Востока; выделить общие тенденции ближневосточной политики двух президентов; проанализировать различия между их ближневосточной политикой. В конечном итоге автор приходит к выводу о преемственности взглядов президентов в 2007–2014 гг., сохранением большинства традиционных контактов и расширением сотрудничества. Изменения заключаются в интенсивности взаимодействия. Так, личные качества и убеждения обоих политиков укрепили одни связи и вызвали охлаждение других, вызвали перестановку некоторых акцентов.

V šolskem letu 2019/20 smo pripravili anketo, s katero smo želeli preveriti razumevanje izbranih 100 frazemov in načine njihovega pomenskega pojasnjevanja. V izpolnjevanje anketnega vprašalnika so bili ob učečih se od 6. razreda do konca srednješolskega izobraževanja vključeni tudi odrasli, in sicer tako učitelji in učiteljice kot tudi tisti, ki opravljajo druge poklice. V članku je izpostavljenih nekaj splošnih ugotovitev, ki jih omogočajo odgovori na anketna vprašanja.

Smiselno uveljavljeni primerjalni pristopi pri jezikovnem učenju na vseh zahtevnostnih stopnjah ustvarjajo sinergijske učinke in pozitivno vplivajo na uspešnost dela, pozitivni prenos jezikovnega znanja pa praviloma spodbujevalno vpliva na učenje drugih/tujih jezikov. Da bi ga omogočili, je treba k učenju in poučevanju jezikov pristopati tudi s spoznavnih in jezikovnoprimerjalnih vidikov, kar velja tudi za nastajajoče učno e-okolje Slovenščina na dlani.
Post-harvest Handling and Senescence in Flower Crops: An Overview
Authors: Verma Jyoti , Singh Parminder
Published: March 2021

Floriculture is an in bloom industry comprises of cut flowers, loose flowers and cut greens. Flowers are climacteric which makes them defenseless for huge post-harvest losses. Senescence is a process that follows physiological maturity and leads to death of the whole plant, organ, tissue or a cell. It is one of the imperative factors determining the longevity of the flower. Post-harvest quality of flowers is affected by the pre-harvest factors, stage of harvest and also by postharvest factors. To have better post-harvest life, indulgence of crop-specific management practices is important.
Crossability Barriers in Interspecific Hybridization of Ricebean [Vigna umbellata (Thunb.) Ohwi and Ohashi] with Other Vigna Species
Authors: Bhardwaj Neelam , Kapoor Tanuja , Sharma Parveen
Published: March 2021

Background: Ricebean [Vigna umbellata (Thunb.) Ohwi and Ohashi] is a multipurpose grain legume of Mid-Himalayan region mainly cultivated for food, fodder, green manure and has emerged as a good alternative to other pulse crops such as blackgram and greengram which do not flourish in this region due to their susceptibility to cold temperature stress. It is well reported that the nutritional value of ricebean is higher as compared to many other legumes of the Vigna family and has some superior qualities greater than greengram, blackgram and cowpea. It is also resistance to drought, diseases and pests specially the storage pests during growth period and possesses high percentage of seed viability. Despite having all the favourable traits, it is not much popular among the farmers due to the late maturity and indeterminate growth habit. Instead, farmers prefer other crops which fit easily into their cropping pattern and are easy to harvest. A little genetic improvement with respect to maturity and growth habit can revive its cultivation and show great results in its production as a valuable crop. Thus, the present investigation was formulated to introgress desired traits from mash and adzukibean into otherwise high yielding ricebean genotypes using inter-specific hybridization. Methods: The present investigation involves the inter-specific hybridization among three Vigna species viz, ricebean (Vigna umbellata), blackgram (Vigna mungo) and adzukibean (Vigna angularis). In the year 2017, six genotypes of ricebean (RBHP-36, RBHP-38, RBHP-43, RBHP-61, RBHP-107 and RBHP-108) were crossed with two genotypes of blackgram (HimMash-1 and Palampur-93) and one genotype of adzukibean (HPU-51) in glasshouse conditions. Result: The study revealed that successful crosses were possible only between ricebean and blackgram. All the Inter-specific crosses showed very low pod set percentage ranging from 0 -4% and F1 germination percentage ranging from 20-42%. Pod set percentage and pods harvested varied with combinations of two parental cultivars of each species for most of the inter-specific hybrids. The successful pod set was observed in 16 out of 36 inter-specific crosses. Highest crossability was observed in blackgram and ricebean crosses. Crossing of adzukibean with ricebean showed poor or no pod set among the entire cross combinations which are attributed to early embryo abortion and degeneration during embryogenesis.
Environmental education using distance learning during the COVID-19 lockdown in Israel
Authors: Assaf Nirit , Gan Dafna
Published: March 2021

Education systems and environmental education professionals have been challenged by the COVID-19 pandemic and the sharp transition to distance learning that has necessitated a rapid response. Environmental education as part of a social-ecological system is dependent on the adaptability and the scope of the change with which the system responds to crisis. It is therefore important to explore the ways in which environmental educators choose to increase students’ proximity to nature under conditions of lockdown. The aim of this study, therefore, was to examine environmental educators’ perspective on and teaching methods for implementing environmental education under distance learning conditions. To this end, we conducted 16 interviews and analysed teaching methods (e.g. videos, lesson plans and written assignments) that were used by Israeli environmental educators in March–April 2020. The findings highlight the creativity of the educators who used a variety of teaching methods, involving active/passive learning and the direct/indirect experience of nature, using nature for observation, investigation and in-depth personal, social and environmental learning. The study’s contribution stems from its exploration of the crisis from the perspective of environmental education in the context of social-ecological systems. Key findings present challenges (e.g. lack of direct outdoor interaction and feedback) and opportunities (e.g. public access to online lectures and the nationwide sharing of teaching materials) that were faced by environmental educators in Israel and that led to the development of diverse teaching methods for contending with the crisis. The study recommends incorporating diverse activities in nature, implementing outdoor teacher training for all teachers and creating professional teacher networks.
Resetting education priorities during COVID-19: Towards equitable learning opportunities through inclusion and equity
Authors: De Klerk Edwin Darrell , Palmer June Monica
Published: March 2021

Worldwide, COVID-19 has affected the most deprived communities the hardest and exposed many systemic inequalities, leaving nations vulnerable and destitute. The need for quality education, while heeding to international mandates, including enacting the sustainable development goals (SDG), has become more apparent in promoting equitable and inclusive education for all, which remains a challenge in South Africa with its inherited inequalities. The purpose of this study was to understand how the COVID-19 challenge refocused the commitment of five principals from rural schools in two education districts of the Northern Cape province of South Africa to address resurfaced historic inequalities, including digital access and fluency to attain an equitable learning environment. Semi-structured emailed interviews were conducted with the participants. A thematic analysis of their experiences of the pandemic through the lens of flexible learning theory, revealed that teachers and learners often experienced discrimination-related stress, especially with virtual learning approaches, as schools often cannot offer remote services to advance learning. Furthermore, the participants voiced their uncompromising commitment to inclusion while engaging teachers and learners in identifying possible problems and proposing solutions post-COVID-19. Though the current crisis seems to have perpetuated and deepened existing inequalities in disadvantaged rural South African schools, some school principals are hopeful that as the reality has now been laid bare, it may prompt more urgent action. The paper recommends that school principals and teachers will have to refocus teaching practices towards flexible, inclusively delivered teaching through working collaboratively across disciplines so that they build their personal resilience and advance their technological skills to meet the demands of remote and online learning during a pandemic and beyond.

In November 2019, scholars and practitioners from ten higher education institutions celebrated the launch of the iKudu project. This project, co-funded by Erasmus+[1], focuses on capacity development for curriculum transformation through internationalisation and development of Collaborative Online International Learning (COIL) virtual exchange. Detailed plans for 2020 were discussed including a series of site visits and face-to-face training. However, the realities of the COVID-19 pandemic disrupted the plans in ways that could not have been foreseen and new ways of thinking and doing came to the fore. Writing from an insider perspective as project partners, in this paper we draw from appreciative inquiry, using a metaphor of a mosaic as our identity, to first provide the background on the iKudu project before sharing the impact of the pandemic on the project’s adapted approach. We then discuss how alongside the focus of iKudu in the delivery of an internationalised and transformed curriculum using COIL, we have, by our very approach as project partners, adopted the principles of COIL exchange. A positive impact of the pandemic was that COIL offered a consciousness raising activity, which we suggest could be used more broadly in order to help academics think about international research practice partnerships, and, as in our situation, how internationalised and decolonised curriculum practices might be approached.

Addressing the wicked problem of feedback during the teaching practicum
Authors: Nel Carisma , Marais Elma
Published: March 2021

COVID-19 affected the teaching practicum placement of approximately 650 fourth year BEd Foundation Phase student teachers at University N in April and July 2020. The teaching practicum is seen as a purposeful, organised, supervised, mentored and assessed educational activity required for the completion of a teacher education programme. During the teaching practicum, the provision of feedback from teacher educators as well as mentor teachers forms an integral part of the learning process and enriches student teachers’ learning experiences. However, student dissatisfaction with feedback during the teaching practicum presents a “wicked” problem that requires a strategic partnership approach between the university and partnership schools as well as between the triad partners of teacher educator, mentor teacher and student teacher. The purpose of this exploratory case study is to provide an overview of student teachers’ perspectives on the innovative use of a social annotation platform to ensure greater collaboration on the “wicked” problem of feedback by all partners during the “learning from practice” component of the teaching practicum. The results indicated that student teachers, teacher educators as well as mentor teachers were actively engaged “on the same page” with constructive dialogic feedback that assisted student teachers to make crucial adjustments to the core practice of explaining/modelling content.
