Result-Based Management System: A Mediating Factor for Employees’ Performance
Authors: Owolabi Temitope J. , Adeosun Oluyemi T.
Published: April 2021

In any organization, human resources stand as vital assets for success; these are to be highly valued in order to achieve the competitive edge. Therefore, human capital policies and practices should be tied to organizational goals. The impact of practices of HRM can be the channel that fuels sustained competitive advantage; therefore, enhancement of organizational performance should be the focus for an organization. Performance management comprises setting expectations, assessing behaviors and results of the employee, giving coaching and feedback, and performance evaluation over time to use in decision making. The aim is to line up individual efforts to achieve organizational goals. To this end, this study attempts to examine result-based management which is synonymous with performance management system, and how it drives employees’ productivity. Utilising the purposive sampling technique, staff within an educational institution were selected in Lagos. It was revealed that setting targets and performance standards would engender the desired productivity in employees. The study therefore recommends a comprehensive performance management system which should also be automated in order to capture key performance indicators of employees.

Authors:   University of Luxembourg, Botes Eloise , Dewaele Jean-Marc ,   Birkbeck, University of London, Greiff Samuel ,   University of Luxembourg
Published: April 2021

Foreign language learners experience a unique type of anxiety during the language learning process: Foreign Language Classroom Anxiety (FLCA). This situation-specific anxiety is frequently examined alongside academic achievement in foreign language courses. The present meta-analysis examined the relationship between FLCA measured through the Foreign Language Classroom Anxiety Scale (FLCAS) and five forms of academic achievement: general academic achievement and four competency-specific outcome scores (reading-, writing-, listening-, and speaking academic achievement). A total of k = 99 effect sizes were analysed with an overall sample size of N = 14,128 in a random-effects model with Pearson correlation coefficients. A moderate negative correlation was found between FLCA and all categories of academic achievement (e.g., general academic achievement: r = -.39; k = 59; N = 12,585). The results of this meta-analysis confirm the negative association between FLCA and academic achievement in foreign language courses.
Exploring Greek EFL Teachers’ Resilience
Authors: Stavraki Christina , Karagianni Evangelia
Published: April 2021

This paper explores the resilience exhibited by 169 Greek English as a Foreign Language (EFL) teachers. A quantitative approach was employed to examine Greek EFL teachers’ resilience in relation to demographic, occupational and school/class characteristics. Data were collected by means of the Teacher Resilience Scale (Daniilidou & Platsidou, 2018). The demographic, occupational and school/class characteristics of the participants were related to a number of specific facets of resilience including social skills, peer support, and persistence among others. The results in the majority of the parameters examined suggests that EFL teachers’ resilience is not affected by demographic, occupational and school/class characteristics. We suggest that the findings of this research can be used to inform the development of targeted interventions towards sustaining and building up EFL teachers’ resilience.
Book Review: Teacher Wellbeing by Sarah Mercer and Tammy Gregersen
Authors: Yoshida Amanda
Published: April 2021

This book could not have come at a better time. Who would have thought that teachers all over the world would be temporarily changing their teaching methods in order to reach their learners? Teachers have had to reach inside themselves as well as out to each other in order to make sudden strides in their knowledge about technology and alternative approaches. Teacher wellbeing has never been more crucial.
Introduction to the Special Issue: The Psychology of Teaching and Learning Content and Language
Authors: Talbot Kyle , Gruber Marie-Theres , Nishida Rieko
Published: April 2021

We are pleased to present the first special issue for the Journal for the Psychology of Language Learning (JPLL). The existence of this journal suggests an increased recognition of the importance of psychological factors in language teaching and learning. Indeed, the once emerging field of the psychology of language learning and teaching (PLLT) seems to have cemented itself as a permanent subdiscipline within applied linguistics. With this special issue we want to take the opportunity to draw attention to the psychological experiences of stakeholders in integrated content and language (ICL) settings. These settings present unique challenges and opportunities for teachers and learners and remain relatively underexplored (cf. De Smet et al., 2018; Doiz & Lasagabaster, 2018; Gierlinger, 2007; Gruber et al., 2020; Moate, 2011; Pappa et al., 2017). As such, our principle aim with this special issue is to draw increased attention to this domain of research in the hopes of uncovering ways to better support teachers and learners in these specific settings.
The Well-being and Job Satisfaction of Secondary CLIL and Tertiary EMI Teachers in Austria
Authors: Hessel Gianna , Talbot Kyle , Gruber Marie-Theres , Mercer Sarah
Published: April 2021

Previous studies have highlighted the unique challenges that may threaten the well-being of teachers in CLIL/ EMI contexts, as well as unique opportunities that may positively impact their well-being (Moate, 2011; Pappa et al., 2017; Talbot et al., 2021). Results from Talbot et al. (2021) suggest that, in the Austrian context, the well-being of secondary CLIL teachers may be more at risk than that of tertiary EMI teachers. As such, the present study aimed to investigate this notion further through a comparative survey examining the well-being and job satisfaction of secondary CLIL and tertiary EMI teachers in Austria. In total, 123 secondary CLIL teachers and 219 tertiary EMI teachers completed the questionnaire survey. Results show that CLIL teachers tended to score consistently lower on several key dimensions related to well-being than EMI teachers, while the differences in job satisfaction were far less pronounced. Thus, the findings of this study lend empirical support to the notion that CLIL teachers at Austrian secondary schools may be more at risk in terms of their well-being than their colleagues at tertiary level. The survey data also provides valuable insights into teacher beliefs associated with professional well-being. An important implication for practice is that those teachers who felt more adequately trained to teach CLIL/EMI classes tended to report significantly higher professional well-being than their colleagues at both the secondary and tertiary level.

Authors: Gemaque Tainára Cunha , Da Silva Sérgio Rodrigues , De Melo Daniele Salgueiro , Da Costa Daniel Pereira , Filho Kleber Campos Miranda
Published: April 2021

Medicinal plants from Amazon have been commercialized for decades, but few scientific studies prove their effectiveness and safety in use in aquaculture activities. The objective of the present study was to use the Amazon river prawn Macrobrachium amazonicum to predict the toxicity of the natural extracts of nine medicinal plants viz pariri Arrabidaea chica, muirapuama Ptychopetalum olacoides, anauerá Licania macrophylla, barbatimão Ouratea hexasperma, faveira Vatairea guianensis, sacaca Croton cajucara, jacareúba Calophyllum brasilliense, pau d’arco Tabebuia sp. and verônica Dalbergia subcymosa, in concentrations of 1, 10, 100, 500 and 1000 µg/mL. The media was prepared in 0.5% dimethyl sulfoxide (DMSO) diluted with water. Ten post-larvae (0.5 ± 0.1 g) were added to each triplicate and, after 24 h, the mortalities were evaluated, with the results of median lethal concentration expressed as LC50-24h using the Probit statistical method. To obtain the concentrations of a common bioactive compound of plant extracts, the concentrations of flavonoids were analyzed using a methodology based on the formation of chromophores. The results of acute toxicity indicate variability in the toxic effects of medicinal plants, taking into account the concentration of total flavonoids, with the least toxic Tabebuia sp. (LC50 = 758.31 µg/mL) and the most toxic C. cajucara and V. guianensis (LC50 = 72.16 and 75.23 µg/mL), respectively. The extracts demonstrated lethality against M. amazonicum, which predicts toxicity and warns of its use them as herbal medicines. More studies must be carried out to determine other bioactive compounds in the plant extracts used since there is an unparalleled availability of chemical diversity.
The Energy Crisis and Environmental Concerns in Sub-Saharan Africa (Nigeria): A Perspective on Public Governance for Climate Action
Authors: Ozohu-Suleiman Abdulhamid
Published: April 2021

The inextricable relationship between environment and development is unarguable, and the literature is replete with scientific evidence of the interdependence between the two phenomena. However, as the interaction between man and nature proceeded from the condition of conviviality to that of belligerence, there has been a marked decline in the resilience of nature to accommodate human avarice. It is nature’s reactions to this unfair transaction that is today called climate change. In Sub-Saharan Africa, climate change remains an intractable problem, or to borrow the words of Pollitt (2016), “a very wicked issue” that challenges state capacity to contain its scourge. Finding a way around this wicked issue has been the preoccupation of public policy scholars and practitioners. Incidentally, combating climate change is a cross cutting issue in the 2030 global agenda for sustainable development which inevitably touches on access to affordable and sustainable energy, protection of the ecosystem to halt biodiversity loss. Consistent with this global agenda is the Africa agenda 2063 with the overarching aspiration of “a prosperous Africa based on inclusive growth and sustainable development”. These multinational initiatives suggest a growing consensus on environmental sustainability as the desideratum of development. In Nigeria, the energy crisis and its attendant consequences on the environment has made the country one of the most vulnerable to climate change in the region. This paper seeks to offer a perspective on public governance for climate action. It argues that lack of state capacity to address the energy requirement of the economy has had grave consequences on environmental resourcefulness. While consensus on multinational agenda is given, the point at issues is for national governments to domesticate this agenda and mobilize the requisite resources to translate them into measurable achievements. The paper observes that apart from the huge deficit in furnishing the energy need of the real sector, the energy crisis poses existential threats such as food insecurity, environmental pollution/degradation through deforestation, flooding and pollution. The paper recommends, among others, that the Nigeria-Germany bilateral cooperation on the power sector should be implemented to its logical conclusion, and that a program of public enlightenment is urgently required to arrest traditional practices that are harmful to environmental sustainability.
Local Government Capacity Development: A Case Study of a South African District Municipality
Authors: Zandamela Horacio , Mphahlele Matuku
Published: April 2021

Bojanala Platinum District Municipality (BPDM), in the North West Province is endowed with the extractive economy. The District experiences challenges of capacity development of service delivery structures and programmes. It is in this context that this paper explains how local government responses to challenges of capacity development in the District Municipality. In addition, the paper explores ways in which they can be overcome for enhanced service delivery. The purpose of this study is to examine challenges related to the use of capacity development structures and programmes related to service delivery and explores how to overcome them. The study examines the structures and programmes, facilitators and inhibitors of skills development and performance initiatives within the context of local government capacity development. This study develops a theoretical framing incorporating scholarship on human capital and performance improvement in the context of local government. This framing is premised on the scholarly evidence that capacity development is an enabler of service delivery, influenced by skills development and municipal performance improvement. The research is a single case qualitative case study approach and employs an interpretative paradigm. The paper employs senior managers in the municipalities as the unit of analysis. That study reveals that there are difficulties associated with skills retention and organisational relations. In conclusion, political abandonment, poor communication and stakeholder engagements contribute to weakened inter-municipal co-operation and inadequate use of resources. The interface between learning and skills development contributes to the body knowledge.
Islamic Chinese Art: Islamic anthology of Chinese calligraphy
Authors: Mohammed Al-Mannai Maryam
Published: April 2021

When Islam spread from the Arabian Peninsula to the rest of the world, it impacted the lives of millions of people. One of the impacts was related to the influence on art, especially when Islam entered China in the 7th century. The Chinese Islamic art was a challenging product due to two major factors. The first factor was that the transition of traditional Arabic calligraphy to Chinese Arabic calligraphy was not straightforward due to the huge difference in how Arabic letters and Chinese characters are displayed. The second factor was related to the translation because the Chinese language uses characters to explain the intended meaning, whereas the Arabic language is an expressive and specific language. This paper provides examples of Chinese Islamic art where errors have been observed in written verses from Qur'an or even in spelling the names of Allah. Moreover, it provides interesting examples of pottery and porcelain pieces that were found and preserved in Qatar Museum as well as in Al-Zubara Fort.

The Role of Social Networks During the COVID-19 Lockdown: Real-Life Social Distancing Vs Virtual Interactions
Authors: Tania Vergura Donata , Luceri Beatrice , Zerbini Cristina
Published: April 2021

Online social networks have become one of the most widely used sources of information in the world and also an important part of our daily life. A huge boost to their spreading came with the outbreak of the COVID-19 pandemic. As social distancing and lockdown orders due to COVID-19 health emergency grew more pervasive, individuals began to spend more time online and to use social networks (SNs) to keep up to date regarding the spread of pandemic and also to maintain communication with friends and family and reduce isolation. Given these evidences, the present study aims to investigate the social supporting role of SNs during the pandemic emergency. Specifically, it intends to analyze (a) the use of SNs as a means of interaction in the face of the social containment imposed by the COVID-19 spreading, and (b) the factors (homophily, trust, loneliness, and emotional instability) that affect such use. An online survey with a sample of 194 Italian people was conducted. Structural equation modelling was used to estimate the model proposed. Results revealed that sense of belonging to SNs had a strong impact on search for social support and is, in turn, positively influenced by trust in SNs and homophily. Emotional instability also increased the search for social support. The study contributes both theoretically and empirically to the understanding of the role of SNs in influencing individual behavior. As the use of SNs continues to spread around the world, understanding why consumers rely in SNs and what gratifications they receive from them is undoubtedly of interest for both academics and practitioners.

Published: April 2021

Współczesna architektura przedszkolna jest wynikiem blisko dwuwiecznej ewolucji założeń funkcjonalno-przestrzennych oraz zmiennych trendów architektonicznych. Celem badawczym było określenie możliwości synergicznego kształtowania architektury przedszkolnej z uwzględnieniem zarówno współczesnych oczekiwań formalnych i funkcjonalnych oraz wymagań techniczno-budowlanych, jak i szeroko rozumianych rozwiązań proekologicznych. Podstawą wniosków były badania przeprowadzone w oparciu o projekt architektoniczno-koncepcyjny energoefektywnego przedszkola w Michałowicach. Wyniki badań pozwoliły na wyciagnięcie wniosku: wymagania formalne, funkcjonalno-przestrzenne
i techniczno-budowlane budynków o tym przeznaczeniu nie stoją zasadniczo w opozycji do zasad kształtowania architektury proekologicznej oraz energooszczędnej.

Technical Debt: A Clean Architecture Implementation
Authors: Beltrão Alessandro Caetano , Farzat Fábio De Almeida , Travassos Guilherme Horta
Published: April 2021

Technical Debt (TD) and Technical Debt Management (TDM) are terms that are receiving increasing attention from practitioners and researchers. They reflect a concern on how shortcuts taken during the software development process can incur negative impacts on software maintainability and how practitioners may use tools and techniques to mitigate the effects of the debt over time. A widely used tool to manage TD on an implementation level is SonarQube with the SQALE method, as it allows developers and managers to track debt over time. However, even SonarQube has its weaknesses since it only provides a set of architecture agnostic rules for TD, and the implementation of new rules can prove to be a challenging job. In this paper, we discuss how, during a real industrial project on a Brazilian software house, we developed a set of rules based on the Clean Architecture model, created a plug-in for SonarQube, and integrated it into our development cycle. At last, the preliminary results show that using a rigorous set of rules allows keeping track of TD on an implementation level.

The Effects of Eight-Week High-Intensity Intermittent Training on Body Composition, Aerobic and Anaerobic Performance, Lipid Profile and Hematological Indices in Sedentary Healthy Overweight Adolescent: A Comparison of Volume
Authors: Hosseini Mohsen , Monazzami Amirabbas
Published: April 2021

Background: Research on the effects of high-intensity intermittent training (HIIT) with different volumes on cardiovascular risk factors is limited. Objectives: The current study aimed to determine the effects of eight-week of high-intensity intermittent training and to compare the volumes of training programs on body composition, fitness factors, and cardiovascular risk factors in overweight students. Methods: There were thirty overweight boys (13 - 16years) as the participants of the study who were randomly divided into three groups, including the control group (n = 10), HIIT-1 (n = 10), and MIIT-2 (n = 10). The HIIT-1 group program included 2 × 8 - 15 sets (100 - 110% MAV), and the HIIT-2 group training program included 4 × 4 - 6 sets (100 - 110% MAV). These training programs continued three times a week for eight weeks. Yo-Yo recovery test, RAST test, and ELISA technique were applied to measure aerobic and anaerobic performance, lipid profile, and hematological indices, respectively. Results: The findings showed that except for anaerobic performance and hematological variables in the HIIT-1 group and hematological variables in the HIIT-2 group, other research variables of the two training groups were significantly different from the pre-test (P < 0.05). Besides, in between-group comparison, the findings revealed that there was a significant difference between VO2max, HDL, and TG as well as anaerobic performance between the HIIT-1 and HIIT-2 groups (P < 0.05). Conclusions: The results suggest that HIIT-1 program is suitable to increase aerobic performance and reduce cardiovascular risk factors, while HIIT-2 program may be applied to increase anaerobic performance because the volume of exercises plays a decisive role in possible adaptation resulting from such exercises.
Subcutaneous Calcification and Fixed Flexion Deformity of the Right Elbow Joint in a Child with a GNAS Mutation: A Case Report
Authors: Alsaffar Hussain , Attia Najya , Senniappan Senthil
Published: April 2021

Introduction: The art of medicine glorifies when a clinician listens carefully to the patient’s story, gives a thorough examination, performs appropriate investigations, and finally links findings together to reach a definite diagnosis. An interesting case was reported here, highlighting the integration of different symptoms and manifestations with some relevant biochemical investigations to reach a final diagnosis. To the best of our knowledge, fixed flexion deformity, as a complication of subcutaneous calcification, has not been previously reported in a child with Albright hereditary osteodystrophy (AHO). Case Presentation: A 2.5-year-old boy was born at term with a birth weight of 3.5 kg (-0.49 SDS). The child was referred to a general pediatrician with a history of right elbow joint swelling noticed initially at six months of age. He then developed the limitation of right upper arm movement, which slowly progressed afterward. The patient had no history of trauma. At nine months of age, he was diagnosed with hypothyroidism, preceded by cold skin, dry hair, and constipation. At nine years of age, he presented with a fixed flexion deformity of the right elbow associated with markedly limited joint movement and symmetrical hands with hyperpigmented knuckles of right metacarpal bones. Subcutaneous masses were felt along the right forearm, showing tenderness on palpation. Investigations revealed elevated serum parathyroid hormone and normal calcium indicating parathyroid hormone resistance. Further genetic testing revealed GNAS mutation. The child was obese throughout his childhood. Conclusions: This case report describes an obese child with subcutaneous calcification that led to fixed flexion deformity of the elbow, starting at an incredibly early age. Hypothyroidism and pseudohypoparathyroidism raised the suspicion of AHO, which was later confirmed by genetic testing. This is the first case report on fixed flexion deformity in a patient with GNAS mutation (c.719-1G > A Chr20: 57484737) in West Asia.

Published: April 2021

Background: Toxoplasmosis is caused by Toxoplasma gondii, a protozoan parasite, and is among the diseases generally referred to as neglected tropical disease (NTD). It can be a reason for impulsive abortion in pregnant women or hereditary chorioretinitis in neonates. Objectives: The present study examined seroprevalence and related risk issues of toxoplasmosis in pregnant women (PTW) and non-pregnant females (NPF) of two health facilities in Port Harcourt. Methods: Venous blood was collected from 380 women and analyzed by immunodiagnostic techniques using ELISA (Enzyme-Linked Immunosorbent assay) IgG and IgM tests and real-time polymerase chain reaction (PCR). Data were collected using a well-structured questionnaire on the socio-demographic risk issues linked with toxoplasmosis. Results: Among the study population, PTW and NPF had seroprevalence of 33.0% and 19.4%, respectively (P < 0.05). PTW recorded a higher overall seroprevalence than NPF with 16.1%, 1.3%, and 8.4%, 0.8% for Toxoplasma gondii ELISA IgG, and IgM tests, respectively. IgM-positive cases were all authenticated by the real-time PCR technique and were all negative. Age group 35-39 years had the highest IgG seroprevalence of 24.3% for PTW, while the age group > 40 years had the highest IgG seroprevalence of 18.2% for NPF. Traders recorded the uppermost seroprevalence of 20.9% and 2.6% for IgG and IgM among PTW, respectively, while teachers and traders recorded the maximum seroprevalence of 15.6% and 1.7% for IgG and IgM among NPF, respectively. Statistical analysis showed that there was no association between the age group, occupation, trimester, and toxoplasmosis. Conclusions: The toxoplasmosis was significantly high in pregnant women. It is recommended that Toxoplasma gondii tests should be included as a routine test during antenatal.
The mechanism of landslide-induced debris flow in geothermal area, Bukit Barisan mountains of Sumatra, Indonesia

Landslides frequently occur in Indonesia, especially in the geothermal areas located on Sumatra's mountainous island. On April 28, 2016, around 04:30 Western Indonesia Time, a landslide-induced debris flow occurred in Lebong District, Bengkulu Province, Indonesia. The source area of the landslide was located at Beriti Hill on the Bukit Barisan Mountain Range. It resulted in 6 fatalities and damage to infrastructures such as geothermal facilities, roads, water pipes, houses, and bridges. Subsequent landslides and debris flows occurred on April 30, May 2, and 3, 2016. Therefore, this study aims to examine the mechanism and to know the most significant contributing factor to the Beriti Hill landslide. Field investigation, soil sampling, XRD analysis, and Lidar analysis were carried out in the research. Beriti Hill is a geothermal area with many manifestations and is composed of volcanic rocks. Alteration processes produced a thick layer of soil from volcanic rocks. The thick soil dominated by clay minerals and steep slopes is the dominant controlling factor of a landslide, triggered by high rainfall intensity. Increasing water saturation in the landslide material due to high rainfall is the most contributing factor to the developing debris flow from the landslide. Debris flows are recurring events based on the Air Kotok river's stratigraphic data downstream of the landslide area. The debris flow material is toxic due to the low pH from the geothermal process. Therefore, the alluvial fan deposit area from Beriti Hill debris flow is a hazard zone and unsuitable for settlement and agriculture. This research shows that a landslide mechanism in a geothermal area was controlled by clay mineral presence due to the alteration process. The future of landslide risk assessment in the geothermal area can be considered by detailing clay type and their characteristic that significantly contributes to debris flow.
The Validity and Reliability of Student Evaluation of Teaching at the National University of Lesotho
Authors: Thetsane Regina
Published: April 2021

Many Higher Education Institutions use the Student Evaluation of Teaching (SET) scale to evaluate the quality of instructors’ teaching. It includes students’ evaluation of the teacher, the teaching process, teaching approaches and the learning outcomes. Due to its reported dubious reliability and validity, and inherent bias in measuring the quality of teaching, SET remains a hotly debated and controversial instrument. This study evaluated thereliability and validity of the SET scale adopted by the National University of Lesotho. Self-administered SET questionnaires were distributed to 104 third- and fourth-year Bachelor of Commerce students to evaluate ten lecturers, resulting in 751 assessment records. The data were analysed using the Statistical Package for the Social Sciences (SPSS) and Partial Least Squares Structural Equation Modelling (PLS-SEM). While the findings suggest that the SET instrument used at the university is reasonably reliable and valid, minor concerns were raised with regard to discriminant validity, and serious concerns in relation to content validity. Based on the existing literature and the psychometric properties of this SET instrument, it is recommended that university management exercise caution in using its results to make evaluative personnel decisions such as promotions, confirmations, and dismissals. It is also recommended that the SET instrument should be revised and validated and be primarily used for formative purposes such as obtaining feedback for the development of individual instructors.

Students' Reflections on the Use of the Zoom Video Conferencing Technology for Online Learning at a South African University
Authors: Mpungose Cedric B.
Published: April 2021

The majority of universities in South Africa offer face-to-face lectures, resulting in the neglect of online lectures, although learning management systems (LMS) have been adopted and are capable of supporting onlinelearning (e-learning). The coronavirus pandemic (COVID-19) forced universities to move fully online and to adopt Video Conferencing Technologies (VCT) to supplement LMS for e-learning. However, most students confront challenges related to a digital divide, raising the question of whether universities are able to address these effectively. This study explored students’ reflections on the use of the Zoom VCT for e-learning at a SouthAfrican university. An interpretive qualitative case study was conducted, with data generated using emailed reflective activities and Zoom focus group discussions with 26 students in a curriculum studies programme.The framework of connectivism was employed and the data were thematically analysed. The study found that Internet access was a major challenge. While most students enjoyed synchronous Zoom discussions, they wereunable to use other Zoom functions for effective engagement. It is thus recommended that the university should develop an e-learning policy and provide the necessary resources and training to students in order to ensure fitness for purpose.

Partnership Dynamics in University-Community Engagement:
Authors: Mutero Innocent T.
Published: April 2021

Cooperation and reciprocity between university actors and community research assistants through university-community engagement has the potential to lead to knowledge creation and improved research uptake.However, there is a paucity of research on the relational dynamics and operating processes in successful partnerships between multi-disciplinary university scientists and community research assistants. This study investigated the case of the Tackling Infections to Benefit Africa (Tiba) research team based at the University of KwaZulu-Natal to identify the attributes associated with constructing and sustaining transformative university-community engagement through multi-disciplinary research teams. Data was collected by means of participant observation, ethnographic conversation interviews, and in-depth interviews with key participants including co- --mmunity research assistants and university-based researchers. The results show that organisational structure and qualities, academic principles and social qualities underpin the success of multi-disciplinary research teams. Based on the findings, we assert that dialogic interaction, respect, ‘demystification of science’ and knowledge plurality facilitate relationships between researchers and community research assistants that can aid in framing sustainable university-community engagement as a way to work with the community rather than ways to work for it.
