Published: July 2024

This paper proposes a damage diagnosis strategy to detect and classify different type of damages in a laboratory offshore-fixed wind turbine model. The proposed method combines an accelerometer sensor network attached to the structure with a conceived algorithm based on principal component analysis (PCA) with quadratic discriminant analysis (QDA). The paradigm of structural health monitoring can be undertaken as a pattern recognition problem (comparison between the data collected from the healthy structure and the current structure to diagnose given a known excitation). However, in this work, as the strategy is designed for wind turbines, only the output data from the sensors is used but the excitation is assumed unknown (as in reality is provided by the wind). The proposed methodology is tested in an experimental laboratory tower modeling an offshore-fixed jacked-type wind turbine. The obtained results show the reliability of the proposed approach. Key words Damage diagnosis, structural health monitoring, wind turbine.

When designing an electric motor drive for a conversion of bicycle to an electric vehicle it is obligatory to determine the required power of the electric motor and the energy of a battery pack. By using a classical method, drive requirements can be established with speed and torque measurement on the drive wheel of the vehicle using a torque meter. The given traction profile is used for the design of the drive. This paper describes the method for estimation of power and required energy of vehicle only by means of global positioning system (GPS). When selecting a GPS device, it is necessary to take the resolution of the device and accuracy of vehicle speed and altitude into account. Using the measured track (speed and altitude profile) and the drag model of the vehicle it is possible to calculate both power that the vehicle develops, and energy consumed for a certain distance. The GPS device measurements, selection of electric drive, bicycle electrification and analysis of processed KTM Knoxville electric bicycle is presented. Keywords: GPS device, longitudinal speed, vehicle drag, estimation, bicycle electrification

Every beautiful piece reflects a labour of love and the story of a dying art. Passed from generation to generation, these skills are now possessed by a few master crafts persons. The art of weaving dried leaves of various plants has been a part of many indigenous cultures for centuries. Mengkuang leaves are commonly used to make household items such as floor mats, rice holders, food covers, and different kinds of bags and baskets. Some new products that have been introduced in recent times include purses and lamp shades, sometimes innovatively combined with textiles to widen their use and appeal. Weaving is a form of art that involves the interlacing of sets of leaf blades processed according to certain disciplines to create mats and house walls which can be seen almost everywhere. Woven products are made from tropical plants and therefore making them widely available in the country. In the art of Mengkuang weaving design, the geometrical shape in weaving is divided into three categories like original geometrical design, natural geometrical design, and arrangement of the geometrical design. The original geometrical designs have existed for many years. The geometrical arrangement design is a combination of the natural geometrical design in producing an abstract. Motifs or Kelarai is a design found in the Mengkuang weaving motifs. Kelarai is a motif that results from a weaving pattern. Kelarai is made in a variety of motifs and its role is the same as the floral pattern in weaving. The name will be different if woven in different shapes, sizes and arrangements. The objective of this study is to analyse the geometrical element in the Mengkuang weaving motifs or Kelarai. A study on geometrical concepts focusing on 8 motifs out of 51 motifs produced by the weavers in Bukit Tanah, Kelantan to analyse mathematical concepts that appear on the Mengkuang weaving motifs.

Authors: Bryan  , Saputri Theresia Ratih Dewi
Published: July 2024

Hipertensi merupakan salah satu penyakit tidak menular yang umum terjadi di dunia. Salah satu penyebab umum hipertensi adalah pola makan yang tidak sehat. Dalam menanggapi hal tersebut, Dietary Approach to Stop Hypertension (DASH) disarankan sebagai pola makan yang efektif untuk mengurangi tekanan darah. Meskipun telah terbukti efektif, penderita hipertensi masih belum dapat menerapkan pola makan tersebut secara konsisten. Salah satu faktor penghambat penerapan pola makan DASH adalah ketidaktahuan penderita hipertensi dalam memodifikasi pola makan sesuai anjuran yang ada. Berdasarkan permasalahan tersebut, penelitian ini bertujuan untuk merancang pembuatan aplikasi pola makan DASH bagi penderita hipertensi berbasis mobile yang dapat memberikan rencana makan sesuai pola makan DASH. Rencana makan dalam jangka waktu tujuh hari yang dibuat setiap harinya meliputi sarapan, makan siang, dan makan malam. Menu makanan akan dirancang dan disesuaikan dengan jumlah kebutuhan kalori harian. Penderita juga dapat memantau asupan natrium sesuai dengan makanan yang telah dikonsumsi. Sebelum mengembangkan aplikasi, usability testing dilakukan menggunakan metode heuristic evaluation untuk mengevaluasi desain pada prototype. Pengembangan aplikasi dilakukan menggunakan metode waterfall model dengan arsitektur BLoC. Aplikasi mobile dikembangkan menggunakan bahasa pemrograman Dart, framework Flutter, Bloc, Firebase, dan Edamam untuk sistem operasi Android. Pengujian black box kemudian dilakukan dengan metode functional testing. Setiap fitur yang diujikan berhasil berjalan sesuai yang diharapkan dan dinyatakan lolos pengujian. Hasil penelitian menunjukkan bahwa aplikasi Milda dapat digunakan oleh penderita hipertensi untuk menjalankan pola makan sehat dengan memberikan rencana makan sesuai dengan pola makan DASH. Rencana makan yang diberikan mendorong penderita hipertensi untuk memulai atau mencoba kembali pola makan DASH. Selain itu, variasi menu makanan yang menarik juga mendorong penderita hipertensi untuk lebih konsisten dalam menjalankan pola makan DASH.

Se analizan, desde diferentes ángulos, el resurgimiento de las políticas proteccionistas en el ámbito del comercio internacional. El triunfo del brexit en el referéndum celebrado a mediados de 2016 en Reino Unido, y la llegada de Donald Trump al poder de los Estados Unidos a inicios de 2017, constituyen los dos principales hitos históricos que marcan el regreso de las tendencias proteccionistas en la economía mundial. El posterior abandono de Estados Unidos al Acuerdo Transpacífico de Cooperación Económica (TTP, por sus siglas en inglés) y la guerra comercial iniciada por este país contra China (y respondida por esta nación en el mismo tenor), no hacen más que corroborar esta nueva tendencia mundial en las políticas de comercio exterior. Frente a esta situación, es necesario y urgente analizar estas políticas y evaluar su impacto sobre la economía internacional, y en particular sobre México. Los trabajos que componen esta obra analizan, desde diferentes perspectivas y enfoques metodológicos, los múltiples aspectos que se relacionan con esta nueva realidad. No obstante, la diversidad en los temas abordados en cada artículo, se puede apreciar en todos ellos una posición crítica con respecto a este proceso antiliberal que se observa en la política comercial de algunos países (sobre todo Estados Unidos desde que Donald Trump asumiera la presidencia).

Treatment of non-Hodgkin lymphomas (NHL) in children using risk-based chemotherapy protocols is currently effective in 80–95% of cases, even in advanced stages of the disease. However, relapsed/refractory forms of NHL (which are less common) have an extremely unfavorable course with low survival rates. The addition of autologous and allogeneic hematopoietic stem cell transplantation (HSCT) to a comprehensive treatment program for relapsed/refractory forms of NHL can improve treatment results due to the antitumor effect of chemotherapy drugs of the conditioning regimen and the graft-versus-tumor effect, which is, however, less significant than in leukemia. Moreover, post-transplant complications after allogeneic HSCT in some cases can offset its positive results in NHL; therefore, to reduce toxicity, especially in severe somatic status of the patient, preference is often given to reduced-intensity conditioning regimens. This article presents two clinical cases. In one case, autologous HSCT was carried out for the first relapse of Burkitt's lymphoma. However, the patient developed a second relapse and underwent allogeneic HSCT from a haploidentical donor. In the second case, HSCT from an unrelated HLA identical donor was carried out in a patient with relapsed anaplastic large cell lymphoma. Both patients received reduced-intensity conditioning regimens. This approach helped to avoid the development of severe post-transplant complications, ensuring successful engraftment and achievement of donor hematopoietic chimerism. Early after transplantation, the patient with relapsed Burkitt's lymphoma developed a second tumor – acute T-lymphoblastic leukemia, from which the patient died. Despite treatment with targeted drug crizotinib, the second patient showed lymphoma progression, which resulted in death. The patients' parents gave consent to the use of their children's data, including photographs, for research purposes and in publications.

Authors: Smirnova D. S.
Published: July 2024

The improvement of treatment outcomes for children with high-risk neuroblastoma is one of the most significant challenges in current pediatric oncology/hematology practice. Treatment outcomes in these patients need to be improved, both in terms of achieving remission and in terms of toxicity profile. At the present time, a number of approaches have been adopted to achieve better outcomes, including the intensification of treatment by using tandem high-dose multiagent chemotherapy followed by autologous hematopoietic stem cell transplantation as a part of treatment. Tandem high-dose chemotherapy with autologous hematopoietic stem cell transplantation has been shown to be effective and safe in several studies. The purpose of this literature review is to present research data showing the feasibility and safety of this treatment strategy in practice.

Authors: Goronkova O. V. , Pavlova A. V. , Raykina E. V.
Published: July 2024

This article presents a brief overview of publications on pediatric aplastic anemia (AA) and closely related conditions. Here we consider the pathophysiology of AA, which includes three main mechanisms of bone marrow destruction resulting in aplasia: direct injury, immune mediated destruction and bone marrow failure resulting from inherited and clonal disorders. New aspects of inherited bone marrow failure syndromes, inborn errors of immunity and myelodysplastic syndromes are highlighted as the most common conditions included in the spectrum of differential diagnosis of AA in children. A comprehensive algorithm for the diagnosis of AA in children is presented, including standard laboratory tests and additional modern molecular and genetic techniques that contribute to a better understanding of this heterogeneous group of diseases and determine approaches to the choice of therapy. The purpose of the review is to provide pediatricians and pediatric hematologists with an updated information of this rare, heterogeneous condition based on an analysis of the latest literature data.

Hemophagocytic syndrome is the primary clinical manifestation in patients with familial hemophagocytic lymphohistiocytosis (HLH) and may also occur as a phenotypic manifestation of other primary immunodeficiencies (PIDs). Allogenic hematopoietic stem cell transplantation (HSCT) is a gold standard therapy for both. In our study, we analyzed the results of HSCT in patients with PIDs associated with HLH. The study was approved by the Independent Ethics Committee and the Scientific Council of the Dmitry Rogachev National Medical Research Center of Pediatric Hematology, Oncology and Immunology. Out of 314 patients with various PIDs who had undergone HSCT at the Dmitry Rogachev National Medical Research Center of Pediatric Hematology, Oncology and Immunology between 2012 and 2020, 44 patients diagnosed with HLH before HSCT were included in our study. They were divided into 2 groups: familial HLH group (patients with defined genetic abnormalities or with typical clinical presentation of familial HLH, n = 24) and Other HLH group (verified cases of other PIDs, n = 20). Pre-HSCT infections occurred in both groups, whilе inflammatory bowel disease, immune cytopenia, arthritis, and vasculitis were observed only in the Other HLH group. The median age at HSCT was 2 years in both groups. Conditioning regimens included one or two alkylators and serotherapy. Peripheral blood with TCRab+/ CD19+ graft depletion was used in 41 patients and native bone marrow in 3 patients. The median time of follow-up was 6.9 years in the familial HLH group and 4.3 years in the Other HLH group (p = 0.012). The rate of graft failure (non-engraftment or rejection) in the familial HLH group was 0.08 (95% confidence interval (CI) 0.02–0.31) vs 0.25 (95% CI 0.12–0.53) in the Other HLH group (p = 0.12). No significant differences in the rates of acute and chronic graft-versus-host-disease and viral reactivations were seen between the groups. The overall survival was 0.92 (95% CI 0.8–1.0) in the familial HLH group and 0.85 (95% CI 0.69–1.0) in the Other HLH group (p = 0.5). The event-free survival (where an event was defined as graft failure, lack of control of HLH in patients with mixed chimerism or death) was 0.83 (95% CI 0.68–0.98) and 0.65 (95% CI 0.44–0.85), respectively (p = 0.17). The patients with PID presenting with hemophagocytic syndrome had lower event-free survival rates and higher risks of graft failure and loss of disease control in mixed chimerism than the patients with familial HLH.

Medulloblastoma (MB) recurrence can manifest in various clinical ways and still remains a major therapeutic challenge. As reported in the international literature, high-dose chemotherapy (HDCT) with autologous hematopoietic stem cell transplantation (auto-HSCT) has low effectiveness and severe toxicity in patients with recurrent MB. Here, we analyzed the effectiveness and tolerability of HDCT with auto-HSCT in 9 pediatric and adolescent patients with MB relapses whose histological samples and magnetic resonance images had been reviewed at the Dmitry Rogachev National Medical Research Center of Pediatric Hematology, Oncology and Immunology from July 2013 till December 2021. The aim of the study was to evaluate the effectiveness of the HDCT with auto-HSCT approach for the treatment of MB relapses in pediatric patients. The study was approved by the Independent Ethics Committee and the Scientific Council of the Dmitry Rogachev National Medical Research Center of Pediatric Hematology, Oncology and Immunology of Ministry of Healthcare of Russia.

Published: July 2024

This study presents a simple yet informative bibliometric analysis of servant leadership literature, aiming to provide a basic overview of its scholarly landscape and identify general trends. We conducted this analysis in September 2023. We focused solely on the Scopus database to understand the current state of servant leadership research. Despite extensive search efforts, we found no similar bibliometric analyses within the servant leadership domain during our study period. Therefore, our focus is to present a brief and straightforward analysis of current research in this field based on identification trends over time, connection between co-occurrence of author keywords, most and less discussed keyword, and areas of high and low concentration. Our findings show an increase in scholarly publications, reflecting a growing acknowledgment of servant leadership’s relevance in management practices. Interconnected keywords and themes such as leadership, transformational leadership, job satisfaction, work engagement, authentic leadership, ethical leadership, organizational citizenship behavior, trust, and leadership development emerge prominently. Additionally, less-discussed keywords such as accountability, core self-evaluations, educational leadership, stewardship, customer orientation, and psychological well-being provide alternative perspectives on these research results. While acknowledging limitations inherent in our bibliometric research, such as potential publication bias and language restrictions, our study offers valuable insights for scholars and practitioners interested in this area.

Noise spectra for calculation the speech transmission index in public address systems
Authors: Dziechciński Paweł
Published: July 2024

To precision calculate the speech transmission index (STI), it is necessary to know the level and spectrum of the interfering noise. Simplified design methods used in public address systems are limited to obtaining an appropriate signal-to-noise ratio based on A weighted sound levels. For this reason, among others, guidelines for designers usually contain information on typical interfering noise levels and do not provide information on the noise spectrum. As shown in the paper, the effect of the noise spectrum on STI can be very high, and when such spectrum cannot be obtained by measurement or computation, standardised spectra appropriate for a given type of noise can be used for STI calculations.

Published: July 2024

Internal security of the state is one of the prerequisites for sustainable development. To ensure the public safety and personal security of citizens, it is necessary to develop effective measures to reduce crime and prevent crime in the future. The starting point for the development and practical implementation of an effective strategy to combat crime or prevent certain crimes is criminological forecasting. Individual forecasting is aimed at determining the possibility of committing a crime (crimes) in the future by a certain person or group of persons. For risk assessment, the following are traditionally used machine learning models. Such models also provide qualitative assessments in the scientific prediction of the likelihood and possibilities of committing a repeat criminal offense. Knowledge gained from the application of machine learning algorithm, can provide justice authorities with anticipatory information that is essential for developing a general concept of combating crime. The development of applied models for crime analysis and forecasting can become a reliable tool to support decision-making in predicting likely criminal behavior in the future and ensuring the internal security of the state. In this paper, the results of the application are presented by the machine-learning algorithms Support Vector Machine (SVM) for assessment of the risk of recidivism of criminal offenses by persons who have already been convicted of such a crime in the past. The data set consisted of the 12,000 criminal defendants’ criminal profile information in Ukraine. The constructed classifier has a high precision (98.67%), recall (97.53%) and is qualitative (AUC is equal 0.981). The created SVM model can be applied to new data set to predict the risk of reoffending by convicted individuals in the future.
Volumetric analysis of pons, middle brain and thalamus by MRI in migraine patients; and evaluation of vertebral artery diameter
Authors: Sahan Mehmet Hamdi , Muluk Nuray Bayar , Kocturk Fatih , Aksamoglu Melih
Published: July 2024

OBJECTIVES. We investigated whether there were atrophic changes in grey matter (pons, midbrain, and thalamus) in migraine patients. Vertebral artery diameters were also evaluated.

MATERIAL AND METHODS. The cranial MRI images of 49 adult migraine-diagnosed patients and 49 adult subjects with normal cranial MRI results were included in the study. In both groups, pons, midbrain, and thalamus volumes, as well as vertebral artery diameters were measured.

RESULTS. There were no significant differences between pons, midbrain, bilateral thalamus volumes and vertebral artery diameters of the migraine and control groups (p>0.05). In the right-sided migraine group, the right thalamus volume was significantly lower than the contralateral side (p<0.05). In the left-sided migraine group, the left thalamus volume was non-significantly lower than the contra-lateral side (p>0.05). In the right-sided and left-sided migraine groups, left vertebral artery diameters were significantly higher than those on the right side (p<0.05). In older migraine patients, pons and midbrain volumes decreased (p<0.05). In longer migraine duration, pons volume decreased (p<0.05). In aura-present migraine patients, right vertebral artery diameters decreased (p<0.05).

CONCLUSION. We concluded that migraine is related to grey matter atrophy in terms of thalamus atrophy on the migraine side. Pons atrophy in longer migraine, and pons and midbrain atrophy in older migraine patients were also detected. Therefore, during the follow-up of the migraine patients, grey matter atrophy should be examined by MRI, and treatment to prevent migraine attacks should be planned.

Published: July 2024

CSU and ABPA seem to have different Type 2 pathogeneses but they can be present at the same time. Here we report a clinical case of a 60-year-old woman affected by ABPA and CSU not controlled by either omalizumab or benralizumab alone. After a 18-month follow-up period of omalizumab and benralizumab combined therapy, both diseases were satisfyingly controlled. The dual biological therapy may be feasible and safe in patients suffering from different diseases contemporarily and uncontrolled by a single therapy. Targeting two different aspects of Type 2 pathogenesis, IgE and IL-5r, provided beneficial control of both diseases with no adverse effects.

Pelvic Floor Distress Inventory (PFDI)-20 Score In Patients With Pelvic Organ Prolaps (POP)
Authors: Yulia Margaretta Sari  , Mila Permata Sari
Published: July 2024

Background :Pelvic organ prolapse (POP) is a common and benign condition in women. It was the fall of one or more components of the vagina and uterus, which allows surrounding organs to herniate into the vaginal area, a disease known as cystocele, rectocele, or enterocele. The PFDI-20 score has been used to evaluate symptoms and quality of life in all POP patients.
Objectives : To analyze the PFDI-20 score in patients with POP.
Method : An observational study involving POP patients was undertaken at RSUP Dr. M. Djamil Padang from December 2023 to January 2024. The variables include demographic information (age, parity, obstetric and gynecological history) gathered from medical records, as well as complaints and POP symptoms obtained through an interview using the Indonesian PFDI-20 score. Data was analyzed univariately and bivariately. Statistical significance was set at p<0.05, and statistical analyzes were conducted using Kruskal-Wallis. The statistical program used for the analysis was SPSS 25.0.
Results : Twenty-eight ladies participated. Their average age was 64.43 years (SD=10.49), parity number was 4.5 (SD=2.2), and PDFI-20 score was 136.61 (SD=54.21). In terms of POP, 53.6% (15) were IV. In terms of prolapse type, all patients had uterine prolapses, with the majority also having cystocele and rectocele (96.4%). Total vaginal hysterectomy (TVH) was performed in 82.1% (23), with over half of the patients undergoing anterior colporrhaphy (AC), posterior colpoperineorrhaphy, or colpocleisis. The majority of the complaints concerned inactive sexual activity (92.0%) and frequency (64.3%). The bivariate analysis with Kruskal Wallis test revealed no statistically significant relationships between PDFI-20 score and degree of POP (p<0.05).
Conclusion : Although we were unable to identify a significant correlation, the PFDI-20 score was demonstrated to be a reliable tool for assessing symptoms and quality of life in all POP patients.

What to Expect in Primigravidae Adolescent Pregnancy with Malaria in Remote Area: A Case Report
Authors: Murtani Christian , Fiona Valerie Muskananfola  , Jeffren Evander Bulan
Published: July 2024

Background: Malaria is an infection transmitted by parasite-infected Anopheles mosquito. Pregnancy is one of the risk factors for infection and worse prognosisCase: Here we present a case of primigravidae adolescent pregnancy with malaria in a remote area. Patient presented with fever 10 days prior. Laboratory work-up showed microcytic hypochromic anemia, grade III thrombocytopenia, positive P. falciparum, and IUFD as disease outcome. The most common malaria-related hematological consequences are anemia and thrombocytopenia. Anemia in malaria is caused by the obligatory destruction of erythrocytes during the acute phase and might be related to bone marrow dyserythropoiesis. Several theories suggest mechanisms of thrombocytopenia in P. falciparum malaria such as increased platelet aggregation, bone marrow alteration, microvascular sequestration, and endothelial activation. Intrauterine Fetal Death (IUFD) might be related to microvasculature blockage or inflammation by the infected erythrocyte (IE). Inflammation in the intervillous regions of the placenta results in placental malaria (PM). PM may cause intrauterine growth restriction, premature delivery, and low birth weight, thus increasing newborn mortality.Conclusion: Malaria in pregnancy has a devastating impact on both mother and fetus. Patientâ€™s characteristics and background greatly influence malaria outcomes and treatment continuity. Holistic treatment is recommended to enhance patient prognosis and health-seeking behavior
Vocational Education and Graduate Struggles in the Eastern Cape, South Africa: A Freirean Approach
Authors: Majola Ezekiel , Powell Lesley , Jordaan Christina
Published: July 2024

This article, rooted in Paulo Freire’s transformative framework, critically examines Technical Vocational Education and Training (TVET), challenging the conventional emphasis on powerful knowledge. Instead, it forefronts contextual factors to unravel power dynamics, privilege, and social inequalities within the educational landscape. The primary aim is to engage in dialogues illuminating issues of power and social justice, offering insights to foster more inclusive and equitable TVET practices. Embracing a Freirean lens, the research article actively seeks transformative practices within TVET by emphasising the potential of dialogue, collaboration, and critical consciousness. It moves beyond merely describing students’ suffering and disappointment, focusing on the intrinsic aspect of Freirean ideas—the development of consciousness through dialogic processes. By incorporating the voices and perspectives of TVET students, the article aims to construct an alternative conceptualisation of TVET education. The article illustrates how dialogues contribute to developing a counterculture of resistance and struggle, aligning with Freire’s theory. It emphasises the transformative power of dialogue in addressing students’ lived experiences, struggles, rights, aspirations, and disappointments. This approach aligns with Freire’s belief that dialogue catalyses positive change and empowerment in education.

Despite the persistent request from educational stakeholders to embrace technical and vocational education training (TVET) for sustainable livelihood and development, enrolment in TVET institutions in developing countries is still very low. This study, therefore, seeks to explore factors for the rebranding of TVET in Ghana. This quantitative study proposed five key strategies to be adopted in rebranding TVET in Ghana: government; training providers; parents and guardians; donor and development partners; and employer-related rebranding strategies. The study reveals that governmental strategies perceived to be critical in the rebranding of TVET in Ghana include offering legislative backing to national TVET policy, mainstreaming vocational education into the general education system, and setting up venture capital to support TVET graduates. Trainers should develop business plans to support training activities, networking, and benchmarking with other providers, and establish strong linkages and collaboration with employers and industry. The findings of this study are critical to the development of Ghana and other developing countries as TVET significantly contributes to developing the skill base of any country and increases the employment rate. Rebranding TVET is a step in the right direction towards implementing government policies.
“Sissy Bitch Boys”: Young Effeminate Men Challenging Heteronormativity in a South African Township
Authors: Philip Shannon
Published: July 2024

This paper explores the ways in which young effeminate gay men in South Africa resist the power of heteronormativity and its disciplining gendered expectations on their bodies, identities and social practices. It analyses both the everyday forms of power and violence that these gay men’s bodies experience in the context of a township, as well as their ability to resist, respond, and, to some extent, creatively dismantle this heteronormative power. The article demonstrates how young gay men—through being and behaving like “sissys,” “bitch boys” and “girly boys”—explicitly claim sexual visibility while seeking to creatively and agentically disrupt the gendered and sexual norms and expectations placed on them within their heteropatriarchal context. The data for this paper were drawn from semi-structured interviews with 12 gay effeminate young men from the township of Alexandra and conducted between 2020–2022.
Shifts in Heteronormative and Gender Normative Perceptions among Students at a South African University: A Decade Later
Authors: Reijer Josien , Smuts Letitia
Published: July 2024

South Africa’s Constitution is one of the most progressive in the world, where it highlights the full and equal enjoyment of all rights and freedoms to persons of any sex, gender, race, or sexual orientation and prohibits any discrimination on this basis. At the same time, since its introduction in 1996, a gap has existed between the Constitution and peoples’ actual lived experiences (particularly those of minority groups). To examine whether heteronormative and gender normative views are shifting, data from two quantitative cross-sectional surveys (2011 and 2021) conducted at an urban South African university were analysed and compared across several statements. The data suggest that a dramatic shift in attitude has taken place in this last decade (2011–2021). University students in 2021 were both significantly less homophobic, as well as expressing fewer heteronormative views compared to 2011. Male students continued to be more homophobic than female students, albeit homophobic attitudes had reduced significantly in both groups. Data also suggest that students were moving away from normative gendered views with a particularly dramatic change amongst female students, especially regarding views on sexual roles. We argue that the drop in homophobic views may be in part explained by a broader liberalisation of attitudes towards traditionally held gender roles and views, as the findings suggest significant shifts toward a more progressive dogma.
Land Matters and Rural Development: 2022

The contribution deals with the most important 2022 developments linked to land in South Africa from a legal perspective. In this regard, the overarching land reform programme's three sub-programmes, redistribution, tenure reform and restitution, are dealt with, reflecting on legislative developments and case law. Despite several land claims being finalised, numerous are outstanding, while the new claims have not been investigated yet. In the case of N’Wandlamharhai Communal Property Association v Westcourt, the court found that the shareholder agreements do not indicate that previous servitudes bind successors-in-title. Two cases dealt with the historical upgrading of informal land rights in urban areas, namely Gauteng Provincial Government: Department of Human Settlements v Pogatsi and Gauteng Provincial Government: Department of Human Settlements v Motasi. In the first case, the court took the passing of time into account, while in the latter case, the occupiers were evicted to give effect to the right to housing of the descendants of the original occupiers. Several cases dealt with the Extension of Security of Tenure Act 62 of 1967, such as Frannero Property Investments 202 (Pty) Ltd v Selapa, where the court clarified who has to prove what about ESTA and the Prevention of Illegal Eviction from and Unlawful Occupation of Land Act 19 of 1998 (PIE). In the Constitutional Court case of Grobler v Phillips, the court focused on only one aspect of the considerations that should be considered for eviction. Developments in the pipeline, in the format of Bills, are also analysed briefly, namely the Prevention of Illegal Eviction from and Unlawful Occupation of Land Amendment Bill [B6-2022], Unlawful Entering on Premises Bill, 2022, Housing Consumer Protection Bill [B10-2021], Deeds Registries Amendment Bill [B28-2022] and the Preservation and Development of Agricultural Land Bill [B8-2021]. Housing, eviction, unlawful occupation of land, and developments linked to deeds and registries are also commented on. The Interim Protection of Informal Land Rights Act 31 of 1996 is extended. The picture concerning land reform remains bleak, although some strides have been made in redistribution, rural development, and the finalisation of restitution claims.
Unpacking the Issue of Progressive Realisation of the Basic Income Grant: A South African Perspective
Authors: Tshoose Itumeleng Clarence , Kgaphola Mokgwati Justice
Published: July 2024

This article examines the issue of progressive realisation of the Basic Income Grant (‘BIG’) in South Africa. The article locates the BIG within the broader framework of the specific provisions of the Constitution of the Republic of South Africa (1996) that pertain to the protection of the socio-economic right to access social security, including, appropriate social assistance. The article investigates the competence, flaws, challenges and prospects of these provisions related to the protection of and access to appropriate social assistance for all. It recognises the polarity of the current social security system in general, and the inequitable social assistance model. Furthermore, this article evaluates whether South Africa is progressively realising the ideals encapsulated under the BIG.
Curriculum Inquiry as a Contextualised Social Practice within an Activity System
Authors: Bester Marianne
Published: July 2024

In educational literature, ample curriculum models adopt product-oriented approaches based on linear, sequential design, review and renewal processes. Correspondingly, managerialism perspectives imposed by external and internal stakeholders, national policy frameworks and quality assurance mechanisms emphasise the technicalities of curriculum inquiry within a bureaucratic system as a means to an end. This paper aims to reposition curriculum inquiry as a contextualised social practice within an activity system. To this end, the six core elements of Engeström’s second-generation Activity Theory were used as an analytic lens to examine the activity system of a coursework-based master’s degree programme in a specialised field of study. This academic programme is a unique offering at a large research-intensive university, contributing to the ‘green’ economy in South Africa. Within this activity system, the existing curriculum of this academic programme constituted the unit of analysis. Curriculum documentation was used as the primary data source. The curriculum data was analysed using the semantics dimension of Maton’s Legitimation Code Theory (LCT). The results and findings of this analysis revealed tensions and contradictions within the activity system of this coursework-based master’s degree programme that constrain its inherent potential to equip students with professional expertise in climate change and sustainable development.
