The multidimensional role of the principal in post-apartheid-South-Africa
Authors: Pietersen Doniwen , Langeveldt Dean , Van Wyk Arrie 
Published: December 2023

The end of apartheid in 1994 brought about radical changes in the South African education system, especially for school principals to manage their own affairs as promulgated in the South African Schools Act. These developments have changed the principal's position irrevocably. However, these changes did not result in the expected outcome in the majority of schools for a number of reasons. Teachers are frequently unsure whether the anticipated changes will have the desired impact in schools. Moreover, principals and teachers have different views on how these changes will affect schools and their work. This paper adopts a conceptual approach that draws on various theories and concepts from the literature on school leadership and management. Understanding the challenges of the school principal's job after apartheid was the aim of the research. The Standards for School Principalship (2015) provided the theoretical framework and basis for this conceptual paper. It should be noted that principals are the most crucial persons in education since they serve as managers and major delivery agents in the educational system. They are the driving force behind improved educational outcomes in South Africa after apartheid. However, it is increasingly uncommon for principals to carry out their multifaceted tasks alone because of how significantly their positions have altered since 1994. All the parties concerned with running a school should receive training and orientation in this respect. The main findings of this paper are that, since the end of apartheid, principals face various challenges in their role, such as lack of resources, support, autonomy, accountability, collaboration, diversity, equity, quality, innovation, and professionalism.
Fragments Shored Against Ruins: Defragmenting India through the Gathering Storm
Authors: Mohan Smithi 
Published: December 2023

Travel between territories which exists contemporaneously is baffling in a psychogeographical sense. What had previously been considered as movement through indifferent space seems to be movement through time, into the future or into the past. The spatial assemblages within which these figures travel each have their own temporality, a rhythm that is produced and maintained by the processes that produce and maintain the human and nonhuman elements of the territory. Therefore travel narrative manifests itself as a narrative of space and difference and consequently travel writing as a format reflects an incessant surge of new concepts, new ways of seeing and being.. In this context, I argue that such an attempt is made by Harish Nambiar in his Defragmenting India: Riding a Bullet through the Gathering Storm, a travelogue narrative of a motorbike trip of the author and his friend across various states. Written in the dramatic backdrop of the 2002 Godhra riots, it provides an account of the various fault lines of Indian society quivering in the temblors that the communal riots of Gujarat sent across the nation. The book maps the urban consciousness of India by juxtaposing lives, issues and situations of educated and the uneducated, craftsman and conservationist, teacher and businessman, daughters and drunks from small towns and non-metro cities of India. It thus succeeds in capturing the undercurrents that flow through the life of a nation, community, city, families and individuals, simultaneously cutting across narrow divisive borders.

AIM: The aim of this study was to determine the knowledge levels of rational drug use, the attitudes to traditional and complementary medicine, and the relationship between these in patients admitted to the Internal Medicine Clinic because of gastrointestinal system bleeding.
METHOD: This descriptive, cross-sectional study was conducted with 124 patients hospitalised in the Internal Medicine Clinic of a training and research hospital with a diagnosis of gastrointestinal bleeding between 01.06.2022 and 01.10.2022.
An Information Form including demographic and clinical characteristics, the Rational Drug Use Scale (RDUS), and the Complementary, Alternative, and Conventional Medicine Attitudes Scale (CACMAS) were applied to the patients. The data obtained were analyzed statistically using SPSS vn. 23.0 software.
RESULTS: For the whole sample of patients hospitalised with a diagnosis of gastrointestinal system bleeding, the mean RDUS points were determined to be 19.8±4.17 and the mean total CACMAS points were 96.76±15. In the subscales of the CACMAS, the mean points were determined to be 28.15±9.42 for philosophical congruence with complementary medicine, 23.23±10.39 for dissatisfaction with conventional medicine, and 45.38±8.18 for holistic balance.
The RDUS points were found to be significantly higher in females (20.33±4.37, p:0.04), patients with a good income status (22.17±4.02, p:0.03) and those who did not use painkillers (21.21±4.00, p:0.01) compared to other subgroups. The CACMAS subscale mean points for philosophical congruence with complementary medicine were determined to be significantly higher in males (29.77±9.52, p:0.03), patients who were single (36.33±9.06, p:0.002), and those who used anticoagulants (32.95±10.77, p: 0.04). The dissatisfaction with conventional medicine subscale points were determined to be significantly higher in females (26.04±9.74, p: 0,03), patients with a low income (30±15.17, p: 0.03) and those who used painkillers (26±10.67, p:0.01), and the holistic balance points were determined to be significantly higher in females (47.24±7.33, p: 0.02) and those who used medication regularly (46.49±8.34, p:0.02) compared to other sub-groups. A statistically significant negative correlation was found between rational drug use and dissatisfaction with conventional medicine (r=-0.381, p

Published: December 2023

The Ag-Ni-Co alloy coating is prepared in the low eutectic solvent system by pulsed power supply technology. Infrared spectroscopy and cyclic voltammetry are used to confirm that the addition of metal salts does not change the low eutectic solvent system. When the current density is 1 A/dm2 and the plating time is 40 min, the plating grain is mainly spherical; the coating is uniform and dense. After testing, the surface-specific resistance of the plating is only 1.295 mΩ·cm2, the microhardness reaches 214.8 HV, and the wear rate reaches 3.1. The corrosion resistance of the plating and the substrate is analyzed by a combination of macroscopic electrochemistry and microarea electrochemistry, and the results show that the corrosion potential of the plating reaches −0.141 V, and the corrosion current density reaches 1.299 × 10−7 A/cm2. The corrosion resistance of the plating is much greater than that of the substrate.

Описан новый широкоугольный оптический инструмент ИНАСАН, который создается в рамках двустороннего рос- сийско-узбекского сотрудничества по астрономии в 2023–2024 гг. Инструмент представляет собой кластер из четы- рех идентичных широкоугольных 28 см телескопов на единой монтировке и предназначен для всенебесных обзоров и фотометрического мониторинга. За одну экспозицию кластер просматривает небесную площадку 7 кв. гр. одно- временно в четырех фотометрических полосах c масштабом пикселя 1.26 ′′ . Приведены и обсуждены технические и оптико-электронные характеристики кластера. Кластер планируется установить на Майданакской астрономиче- ской обсерватории АИ АН РУз, которая характеризуется большим количеством ясного ночного времени (около 2500 часов в год) с устойчивым и высоким медианным качеством изображения (лучше 0.7 ′′ ). Кластер ИНАСАН станет одним из наиболее информативных позиционно-фотометрических комплексов в РФ и будет востребован в мировой сети многоцветных широкоугольных оптических телескопов, включая астрономические сети БРИКС.
A new INASAN wide field optical instrument is described. It has been created in frame of bilateral Russian-Uzbek collaboration on astronomy in 2023–2024. The instrument is a cluster of 4 identical wide field 28 cm telescopes on a common mount designed for the all-sky surveys and photometric monitor. For a single exposure, the cluster gets an image of 7 square degree field simultaneously in 4 photometric bands with 1.26 arcsec pixel scale. Technical and optoelectronic characteristics of the cluster are presented and discussed. It’s planned to install the cluster at the Maidanak Astronomical Observatory of UBAI which has a large amount of clear night time (about 2500 hours per year) with a stable and high median seeing of 0.7 arcsec. The INASAN cluster will become one of the most informative positional photometric multi-band observation systems in the Russian Federation. It will also be useful in a global network of multi-band wide field optical instruments including BRICS astronomical networks.
TUNDRA, SPIRITUS, MADAM WIG AND HE-GOAT: A STUDY OF NICKNAMES OF TEACHERS IN TWO GHANAIAN GIRLS’ SENIOR HIGH SCHOOLS
Authors: Wisdom Kofi Vifah  , Joseph Benjamin Archibald Afful  , Lydia Abena Amako  
Published: December 2023

Nicknaming is a common practice in most academic environments. This study investigated nicknames students used for teachers in two girls’ Senior High Schools in Ghana, utilising Scott’s (1990) Sociological Theory on Resistance to Domination. Employing an ethnographic approach that includes participant observations, semi-structured interviews, and informal interactions with the students, the study revealed that ‘namers’ secretly nicknamed their referents and used these names in the absence of the ‘named’ mostly in informal conversations in both inside and outside of the classrooms. These nicknames are used to identify the teachers’ characteristics inside and outside the classroom, focusing on the teachers’ speech behaviours, fashion lifestyles, physical appearances, and personal habits. A key significance of the findings is that they contribute to the extant literature on nicknaming practices from a site that has been under-researched. Further, the study is a significant foundation for future exploration of students’ use of nicknames for teachers in Senior High Schools and other academic settings in Ghana and elsewhere. The study also has implications on the structure and use of language in the senior high school environments as most of the nicknames are coined in the English language and Twi.
