Food security is the major issue in Pakistan due to exponential increase in its population. Pakistan’ economy is highly dependent upon its agriculture sector which especially relies on its major crops. There is a huge gap between the output and actual requirements of food produce. The extensive cropping system over the years and specific crop rotation on the same organic matter are speedily converting productive and fertile soils into barren soils which are causing not only quantitative but also qualitative loss of crop outcome.  There is a dire need to promote the use of non-conventional approached along with conventional approaches for maximum production of crops especially maize. In University of Agriculture Faisalabad a field trial was carried out at experimental area to figure out the effect of integrated nitrogen management on growth and yield of maize. In the experiment RCBD design was used with four replications. The integrated effect of potassium humate, compost and inorganic fertilizers on growth and yield of maize was studied under field conditions. Where humic acid @ 5 L ha-1 and compost @ 100 kg ha-1 along with NPK at @ 175:150:100 kg ha-1 were applied. Plant height, ear leaf length, number of grains per cob, grain yield, Chlorophyll content in leaves, nitrogen contents in grain and leaves and various other growth parameters were recorded at maturity. Integrated use of compost and humic acid along with NPK significantly affected all growth and yield parameters.

Authors: JAIN RADHA , PATHAK A. D.
Published: July 2023

Waterlogging is a major abiotic factor in tropics and subtropics India affecting plant productivity by creating anoxia, aerial rooting, mineral deficiency and toxicity, physiological and biochemical alterations. In present study, an effort was made to evaluate changes in photosynthetic pigments, chlorophyll a (Chl a), chlorophyll b (Chl b), total Chl (Chl a+Chl b), carotenoids (CAR), the ratio of Chl a and Chl b (Chl a/b) and total Chl/CAR ratio and Soil plant analysis development  (SPAD)  index in plants grown under waterlogged conditions (WL) along with untreated control (C) using four sugarcane cultivars; CoLk 94184, BO 91, CoS 767 and CoJ 64. The results obtained indicated variation in Chl a, b, total Chl contents (mg/g fresh wt.) among different cultivars and relatively less in waterlogged plants. Chl ranged between 1.277-2.300 (mean: 1.949 in control) and 1.057- 2.150 (mean: 1.716 in waterlogged), Chl b, 0.319- 0.607 (mean: 0.518) in control and 0.290- 0.571 (mean: 0.453) in waterlogged plants, respectively. Chl a/b ratio is slightly higher in waterlogged (3.640-3.957, mean: 3.794) as compared to control (3.610-3.997, mean: 3.789) plants except in CoJ 64, while total Chl/ CAR ratio was comparatively lesser in waterlogged plants as compared to untreated control. SPAD index was relatively higher in control (30.1 - 35.3, mean: 34.0) than waterlogged plants (22.4-34.1, mean: 29.6) similar to destructive analysis of chlorophyll contents. Carotenoids contents ranged from 0.477- 0.787 in control and 0.467-0.797 mg/g fresh wt in waterlogging treatment; BO91 and CoS767 cultivars showed slightly higher value in waterlogged. Correlation among different attributes indicated significant positive relationship except chlorophyll a/b ratio showing negative association. Cultivar CoJ 64 showed highest decrease in Chl a/b, total Chl/CAR ratio and CAR contents reflecting highly sensitive to waterlogging stress as compared to other cultivars studied.

Published: July 2023

Awar-awar (Ficus septica), belonging to the Moraceae family, has the potential to be developed as an anticancer agent. Cultivating this plant requires technology to produce rapid quality seedlings since generative propagation still becomes a problem due to the extended period in seed production. Therefore, the purpose of this research is to analyze the use of indole butyric acid (IBA) in obtaining quality cutting types of awar-awar. Several IBA concentrations of 0 (control), 100, 200, and 400 ppm were applied on three types of cuttings, namely the apical, middle, and basal stem cutting, each measuring 20 cm. A completely randomized design (CRD) was employed, the data were analyzed using F-test (ANOVA), and significance between treatments were determined using Duncan’s multiple range test (DMRT) at a 5% level of significance. The growth of various cuttings was barely on the average of 57%​, with the optimum growth percentage from the shoots at 75%. Except for root length, the cutting origin types affected growth percentage, shoot number, leave number, shoot/sprout length, and root weight, while the IBA concentration had an impact on the shoot length and root formation (both length and weight). Additionally, the cutting origin and IBA interactions contributed substantially to the root weight. Furthermore, the highest number of shoots and leaves were obtained from the middle stem cutting, while the longest shoots and the highest root weight were obtained from the 200 ppm applications. Middle stem cutting of F. septica treated with IBA 200 ppm showed superior growth.

The demand of high fodder yielding varieties of alfalfa with better nutritional quality is increasing by the livestock farmers. The cultivation of high yielding fodder crops is compulsory need of  the  era for livestock  industry development,  especially in developing countries like Pakistan. Development of high fodder yielding varieties suitable for conservation is a dire need to combat the scarcity of fodders during lean period for this region. In this regard Fodder Research Institute, Sargodha, Pakistan has developed a new alfalfa variety ‘Sarsabz’ having high green fodder yield and better nutritional value with value added quality of hay making due to more number of leaves per plant and less leaves shedding attributes. This variety is an outcome of the selection from base population developed by random mating of five different lines NO.1107; NO.64, R-793, NO.565-85and Sunder during 2006-2019. It has proved its worth in all yield trials and its performance is better than the existing Sargodha Lucerne variety. It produced 6.55% and 11.34% higher green fodder yield as compared to check variety Sargodha Lucerne in National Uniform Fodder Yield Trials. Moreover, its green fodder contains 25% dry matter, 19.6 % protein, 22.7% crude fiber and 1.98% crude fat. The new variety showed better tolerance against diseases (Anthracnose& Stem/Crown rot). Agronomic studies revealed that it is fit in a better way with the existing agronomic practices.

Published: July 2023

Tomato (Solanum lycopersicum Mill.) is one of the most important Solanaceous vegetable crops cultivated widely all over the world. The edible coating is the material that is used for the improvement and maintenance of shelf life and quality of tomato fruit by reducing the respiration rate from the fruit surface. It is eco-friendly and an alternative to synthetic packaging material. Thus, the present investigation was carried out to assess the effect of various edible coatings on the shelf life of tomatoes in the Horticulture Research Lab of School of Agriculture, ITM University, Gwalior, M.P., India in May 2022. The experiment was laid out in Completely Randomized Design (CRD) with three replications. Each replication was comprised of ten treatment combinations of various edible coatings viz., T0 (Control), T1 (Kaolin @ 0.75%), T2 (Kaolin @ 1.25%), T3 (Kaolin @ 2.25%), T4 (Chitosan @ 1.50%), T5 (Chitosan @ 2.00%), T6 (Chitosan @ 2.50%), T7 (Wax @ 0.75), T8 (Wax @ 1.25%) and T9 (Wax @ 2.25%) were used for induced the shelf life of tomato. Results showed that the use of different edible coatings significantly influenced the shelf life and quality of tomato fruits. It was recorded that edible coating treatment T4 (Kaolin @ 2.25%) was found the superior treatment as compared to other edible coating treatments and it gave the maximum physical parameters and biochemical parameters. However, the minimum physical parameters and biochemical parameters were recorded under control treatment T0. Therefore, on the basis of the present study, it may be concluded that the Kaolin @ 2.25 =% was best for the improving shelf life and quality of tomato fruit.

Terminalia arjuna is potential medicinal plant for the well-being of humans and animals since ancient times. Nowadays, synthetic antibiotics are widely used to fight microbial infectious diseases; the agar well diffusion method was used in this in vitro antibacterial study. A total of six microbial strains were tested for the antibacterial potential of bark extracts in solvents such as aqueous,chloroform and ethanol. Proteus mirabilis, Escherichia coli, Salmonella typhi, Klebsiella pneumonia, Streptococcus mutans, and Staphylococcus aureus were acquired from a well-known research organization (ATCC). Finally, an aqueous extract of T. arjuna bark was found to have maximum zones of inhibition (8 mm) against P. mirabilis. Also, the chloroform extract of T. arjuna bark was found to have maximum zones of inhibition (8 mm) against K. pneumonia. Whereas, the ethanolic extract of T. arjuna was found to have significant inhibition zones against all the microbial strains. This ethanolic extract was subjected to GC-MS analysis based on the activity of zones of inhibition. In this GC-MS analysis we detected almost fifteen phyto-components and the majority of these phyto-components are alkaloids and flavonoids.

Published: July 2023

The OMP is a conserved and major outer membrane protein presented on the surface of Candidatus Liberibacter asiaticus (CLas). High expression level of recombinant outer membrane protein (OMP) in Escherichia coli led to form inclusion bodies (IBs) in cytoplasmic space which is an inactive form of protein and needs a solubilizing and refolding process. The aim of this study was to compare different methods for solubilization and refolding of recombinant OMP expressed in E. coli. For this aim, preliminary washing process was performed by Triton X-100 and sodium deoxycholate. To solubilize IBs, reducing agents; guanidine-hydrochloride, urea, β-mercaptoethanol and dithiothritol were applied. The results of washing process showed that applying of 0.5% TritonX-100 (v/v) is led to highest protein recovery. The results obtained from solubilization step revealed that applying guanidine-hydrochloride denaturing agent is led to obtain more solubilized protein. Furthermore, adding supplementary β-mercaptoethanol in denaturing buffer resulted to improve protein recovery during solubilization process. Presence of arginine in refolding buffer containing high urea concentration was led to significant decreases in aggregation. As a result, the best recovery of OMP was obtained at a concentration 0.5 M of Triton X-100, the high efficiency of solubility was found in pH 8 in the presence of guanidine-hydrochloride and the best efficiency of refolding was attained by final buffer containing 2M urea and 0.5 M L-Arginine. These results suggested a suitable procedure to produce appropriate recombinant OMP for preparation of poly and monoclonal antibodies.

Rapid advancement in technology had made the smooth survival of the human race in this 21st century. Besides these serious global disastrous diseases, hazards often emerged out. The human race has faced a serious health emergency due to the emergence of coronavirus first recognized in 2019 which is characterized by pneumonia, lymphopenia, dead lymphocytes, and a cytokine gust or infusion reaction. SARS-CoV-2 belongs to the Coronaviridae family, a family of pleomorphic ss (+) RNA viruses. Its genome is associated with the N protein forming the nucleocapsid, coated with a spike glycoprotein-adorned membrane. it is reported that COVID-19 is primarily transmitted human-to-human via oral and respiratory aerosols and droplets with the virus-contaminated environment play a lesser role in the propagation of disease. Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) is rapidly spreading worldwide, and WHO declared the outbreak of this disease a pandemic on March 11, 2020.Before curative drugs or vaccines are available, most countries implement a series of non-pharmaceutical interventions (NPIs) including wearing masks, testing and tracing suspected cases, social distancing and even locking down COVID-19 epidemic centers. Although these NPIs have appeared to be effective in mitigating the initial wave of COVID-19, continually emerged COVID-19. Hence, in the current scenario, is has now become essential to control and finally irradicate this deadly disease using an effective vaccine. Researchers are engaged in the study of this life-threatening virus, and also they are successful to develop vaccines, UK has become the first to approve Pfizer/ BioNTech COVID-19 vaccine and in India the first is Covi-shield (Adenovirus vector-based by Serum Institute of India Astra Zeneca based model with Research name: AZD1222 (ChAdOx1).The second is Covaxin (on Astra Zeneca model-based developed by Bharat Biotech). In approximately about two years globally every country got suffered from this pandemic.

földrajzi tájakhoz fűződő identitástudat rétegei

Published: July 2023

A természetes és az átalakított kulturtájak egyaránt komoly szerepet játszanak az ember személyes, csoport, nemzeti, vagy nemzetiségi, de még kontinentális önazonosságának kialakulásában is. Az utóbbi években – egyértelműen a globalizációs tendenciák ellensúlyozására – Európában intézményesen is ösztönzik a helyhez, környezethez, tájhoz kötődés erősítését (ld. European Landscape Convention). Felismerték ui., hogy az identitás életminőséget javító erőket szabadít fel, a kisközösségtől kontinentális szintig pozitív szerepe van a társadalmi fejlődésben. Az egyéni tájidentitás gyakran irányul tájesztétikailag, vagy ökológiailag kevésbé értékes tájakra, tájrészletekre. Ezzel szemben minél magasabb szintű közösség identitásának tárgya egy adott táj, annál inkább szerepet játszik benne az esztétikai minőség, és a történelmi jelentőség. Európa számos tájának történelmi fejlődése évszázadok óta szervesen követi az általános társadalmi-gazdasági fejlődést. Ez erős ún. tájkoherencia szintet eredményez, és az ilyen tájak különösen alkalmasak arra, hogy lakóiból magasfokú identitásérzést váltson ki.Atájakhoz kötődő identitásérzés kialakulását több közösségi szinten megfigyelhetjük. Ezek között viszonylag új az „európaiság-érzés” erősödése. Különösen az idegen elnyomás alól frissen felszabadult kisnemzetek élik át eleven erővel a nemzeti önazonosság különböző formáit – köztük a jellegzetes „nemzetinek” nevezhető tájak ápolását.A tájidentitás tárgya, a tájkarakter elsősorban a tájak vizuális megjelenésében nyilvánul meg, de sok példa van arra, hogy a tájidentitásnak elválaszthatatlan része néhány illat- és hangeffektus (smellscape, soundscape) is.Kezdeti próbálkozások vannak a tájakhoz fűződő identitás mérésére. Több tudományos értékű projekt próbálkozik megfelelő indikátor megállapításával. Ezek közül az esztétikai attraktivitás mellett használhatónak tűnik néhány kifejezetten geográfiai adat, pl. a tájhasználati állandóság, a tradicionális földhasználat aránya, a beépítéssűrűség, a tájmintázat szegélyhatás-mutatója, stb.

Germination of Erysimum pieninicum and Erysimum odoratum seeds after various storage conditions
Authors: Csontos Péter , Rucinska Anna , Puchalski Jerzy T.
Published: July 2023

Erysimum pieninicum and E. odoratum have similar morphology and habitat preference, however biogeography of the two species is contrasting. E. pieninicum is a narrow endemic, expressing a very limited distribution in SE Poland, whereas E. odoratum is rather frequent in Hungary and the surrounding countries. The aim of this paper is to investigate the germination behaviour of the two species and to highlight if the differences in the germination of the two species could be related with their distribution patterns.Prior to germination tests, seeds of the two species were subjected to three different storage conditions:1) room temperature (RT); 2) room temperature followed by 40 days at +4 °C before germination test (CT); 3) eight years storage in liquid nitrogen (LN) (for E. pieninicum only). After surface sterilisation of the seeds germination tests in Petri-dishes were initiated on 5th March 2009, and were terminated after 25 days.The studied Erysimum species germinated very fast showing a germination pattern of “Erysimum wittmannii type” sensu Czarnecka  and Władyka  (2007). E. odoratum expressed a relatively low rate of total germination percentage (around 20%) that does not correspond previous reports. The very high germination rate of E. pieninicum (around 97% and 99%) found in RT and CT treatments, respectively, agrees with results of Czarnecka and Władyka. Cold treatment did not influence germination of the studied Erysimum species. In case of the LN treatment E. pieninicum retained a high rate of germination (81.65%).Considering the results of the present study and also the published results of other researchers, germination behaviour of E. pieninicum does not seem to be a limiting factor for the distribution of this species. According to their seed biological characteristics (preserved viability in seed gene banks for long time and sudden germination without the need of dormancy breaking treatments) E. pieninicum and E. odoratum are promising candidates for nature conservation and habitat restoration projects.

Authors: Schweickardt Gustavo
Published: July 2023

El presente trabajo propone un modelo de ecuaciones estructurales basado en la estructura de la varianza-covarianza (CB-SEM), para medir la calidad de servicio técnico percibida por los usuarios residenciales en un sistema de distribución eléctrica. El enfoque adoptado establece un correlato entre los indicadores objetivos, utilizados normativamente, y la percepción que los usuarios tienen de sus efectos. Se incorpora, además, un factor no controlado regulatoriamente: la atención recibida por los usuarios ante reclamos por interrupciones no programadas del suministro eléctrico. Son evaluados diferentes modelos que sirvan a las relaciones estructurales identificadas, para finalmente definir el de mayor validez y mejor ajuste, conforme los indicadores que se emplean para esta técnica. Los resultados permiten observar que cada constructo representa adecuadamente un índice objetivo, y que la atención ante reclamos tiene un impacto sustancial en la calidad medida. El sistema de distribución analizado pertenece a la ciudad de Bariloche, Argentina, y los datos utilizados corresponden a una encuesta realizada durante el año 2021.

La crise que traverse l’université congolaise depuis plusieurs décennies est bien connue par ceux qui s’intéressent à l’enseignement universitaire en Afrique. Elle est souvent expliquée par les conditions déplorables et les moyens dérisoires avec lesquels l’université fonctionne. Et du coup, on se demande pourquoi l’Etat congolais laisse son université dans cet état. Nous proposons ici une hypothèse pour le comprendre : l’université congolaise paie le prix de sa résistance au pouvoir politique en place. Par conséquent, sa réhabilitation passe par une « réconciliation » avec le pouvoir. Mais qui doit se réconcilier avec qui ? L’université congolaise ayant continué, malgré tout, à fonctionner tant bien que mal, à remplir ses missions reconnues à toute université, c’est à l’Etat congolais de sortir son université de l’embargo dans lequel il l’a soumise. Toute autre solution ne sera que palliative et n’apportera pas de résultats durables.
5 - The Dynamics of University Transformation: A Case Study in the Eastern Cape Province of South Africa
Authors: Rómulo Pinheiro  , Gerald Wangenge Ouma  , Pundy Pillay
Published: July 2023

This article sheds light on the dynamics of the recently created Nelson Mandela Metropolitan University (NMMU) as a result of a merger between three separate institutions. A particular focus is given to NMMU’s role in the further development of the Eastern Cape Province, one of South Africa’s poorest regions. The article discusses the impact of the amalgamation pro- cess on the university’s institutional profile, strategic platform, structural features, and scope and nature of activities. The article draws upon key insights from the institutional theory of organisations and the concepts of academic core, extended periphery and structural coupling. Taking institutionalisation as a conceptual frame of reference, it points to a number of tensions and critical success factors with respect to the university’s abil- ity to respond to external demands for a stronger engagement with sur- rounding society. Path-dependencies, local champions, and support by lead- ership structures were found to be major enablers. The lack of a strong and balanced academic core and the absence of structural linkages or tight cou- pling were identified as major challenges.

1 - Continuity and Change in Students’Account of Race and Class Relations at a South African University
Authors: Deevia Bhana
Published: July 2023

This article draws from an interview-based study of students at the University of KwaZulu-Natal highlighting the ways in which they give meaning to race. Racist practices at universities in South Africa have received widespread condemnation and universities are at the forefront in confronting and dealing with the persistence of racism. In this context, the article seeks to develop an understanding of the contextually specific ways through which race is given content and the possibilities that they may present for change. The data shows that the specific configurations of race as described by African and Indian students at the university where the study was conducted suggest constrictions and continuities of separateness as they demonstrate change. Rejecting an analysis that is based on fixed meanings of race, the article theorises that race is complicated by broader social structures, and class remains an important variable in race relations. Race continues to be salient in the everyday lives of students but race and student life must be understood through class. The article analyses further the ways in which students point to possibilities to enhance change working creatively within the university to bring about racial mixing. The article concludes with some recommendations for change.
4 - Reengineering Postgraduate Curricula and its Mode of Delivery: Graduate Students’ Views of Modular Course Delivery at Addis Ababa University
Authors: Solomon Areaya  , Ayalew Shibeshi  , Daniel Tefera
Published: July 2023

The purpose of this study was to examine the graduate students’ views regarding the modular course delivery of the master’s programme in Addis Ababa University. It attempted to answer four basic questions: what are the attitudes of the graduate students towards the modular curricula and block teaching mode of delivery? Is there any difference in students’ preference for modular delivery across different colleges/subjects/disciplines? What are the major strengths and weaknesses of modular course delivery as perceived by graduate students? And what are the outstanding academic and administrative problems encountered by the modular course delivery? The study used the survey method supported by qualitative data collection procedures. Questionnaire was employed to collect data from 732 first year graduate students. However, analysis was made on properly completed and returned 724 questionnaires. Besides six focus group discussions were held. The quantitative data were analyzed by using percentages, means and composite scores, standard deviations and analysis of variance and Tukey HSD. The results showed that graduate students’ overall attitude toward the modular programme is positive. The modular delivery was also perceived favorably. However, significant differences were observed between students of different colleges with regard to attitude towards the modular programme, modular delivery and availability and accessibility of module related materials.
4 - Rethinking the Role of Universities in Africa: Leadership as a Missing Link in Explaining University Performance in Uganda
Authors: Roberts Kabeba Muriisa
Published: July 2023

The subject of this paper is the place of leadership in redefining the role of the university in Africa in general and Uganda in particular. The ‘African University’ today, like any other university, has clear mandates and roles; research, teaching and community service, clearly laid down on paper in many of the universities’ manuals and strategic plans. But, in reality, these roles are not performed at all or are performed in a manner that may not warrant clear roles. Increasingly, it is observed that less quality teaching, less research, and less community service are being done. This situation calls for rethinking what role should universities play. While many expla- nations have been offered for the declining performance of the university, in this paper I contend that leadership plays a significant role not only in influencing escalation of crises but also in averting them, especially in Ugandan universities. The paper answers mainly three research questions: (i) How do changes and transitions taking place in the university sector affect the role of universities in Uganda? (ii) How does leadership respond to the challenges faced by universities? and (iii) What are the challenges faced by leadership and how do these challenges influence their response to university challenges? Using different documents, and basing on the behaviour approaches to study organisations the study makes an analysis of the role of leadership in the functioning of the university. The paper concludes faced with many challenges, universities have changed course and focus and that they need rethinking their roles. It is concluded that the role of leadership has been overlooked yet they occupy a central role in the performance of the university.

1 - The Shifting Landscape of Development Cooperation: Repercussions for African Higher Education
Authors: Damtew Teferra
Published: July 2023

The higher education system in Africa is typically an amalgam of European and American higher education models. The system was built through the conception, direct intervention and support of the colonialists before other important players, such as private foundations, joined in. By design, African higher education was expected to become part of the global higher education system – albeit marginally – and without the consent of Africans. Nevertheless, the dynamics of development cooperation has been evolving with the emergence of new global players, the diminishing influence of the North, and sustained economic growth in Africa. This article (i) explores prospects and challenges based on recent developments and past experience; (ii) analyses current and emerging global trends; and (iii) concludes, with views, on what Africa ought to be doing by way of higher education partnerships.
9 - School–University Partnerships for Professional Development of Teachers: A Case of Lesson Study Intervention in Mathematics
Authors: Jita Loyiso C. , Letloenyane Maleho D.
Published: July 2023

School–university partnerships for the professional development of teach- ers continue to be used extensively in South Africa to enhance the quality of teaching and learning, especially in mathematics. The success of such partnerships in changing teachers’ classroom practices, however, remains in doubt, in part because very few studies present empirical evidence of the changes. This paper assesses the impact of one such partnership, which resulted in perceived changes in teachers’ instructional practices and curriculum decisions after the intervention. Using retrospective pre- testing design, the study established that there were significant differences between teachers’ pre- and post-test scores, which suggests that teachers changed their instructional practices and curriculum decisions after the intervention. The findings provide some empirical evidence that partner- ships of this nature, between schools and universities, may prove valuable in attempts to improve the teaching of school mathematics, especially in the South African context.
12 - Accounting Teacher Preparation: A Critical Accounting Perspective
Authors: Qhosola Makeresemese R.
Published: July 2023

The aim of this article is to reflect on and analyse the preparation of account- ing teachers from the perspective of critical accounting as the theoretical framework. There are many challenges in the Further Education and Training (FET) school accounting classrooms where teachers struggle with knowl- edge content, pedagogical content knowledge, and knowledge of teaching accounting, as well as classroom practices. In this article we argue that many of these challenges could be resolved if we adopt principles and ideas from critical accounting as bases for preparing aspiring teachers. Critical account- ing is also the theoretical framework within which we couch the study since it encourages the optimal learning of accounting. Such improved quality, as argued here, is marked by effective teaching and learning strategies which are learner-centred, promote self-regulated learning, and are compatible with the prescripts of the democratic constitution of the country such as equity, social justice, peace, freedom and hope. The article concludes by arguing that critical accounting is not separate from accounting practice in general. Instead, it is seen as the means of reflecting or interacting with accounting information in order to challenge the hegemonic and counter-transformatory understandings that are conventionally generated to disempower and further marginalize subaltern communities. Critical accounting is used as both the lens and the mode of teacher preparation. As a mode of teaching it seems to hold the promise of teaching accounting which is more than just ‘training for work’ and ‘skill development’. It is an approach geared towards actualizing aspirations for the individual, in terms of social and economic well-being, in ways that empower and transform. This article therefore considers the challenges of teaching and learning accounting and suggests ways in which these could be resolved through a teacher preparation approach which is grounded in critical accounting strategies.
