ABSTRACT Tomato cultivation is highly demanding on the supply of water throughout its phenological cycle, especially in regions where rainfall is irregular or scarce. Given the above, the objective of this study was to analyze the viability of thermal index for determining water deficit in cherry tomato under different strategies of controlled deficit irrigation and use of a hydrogel-type soil conditioner. The experimental design adopted was randomized blocks in a 5 × 2 split-plot arrangement, referring to the irrigation strategies (FI - Full irrigation, RD - Regular deficit irrigation, with a continuously applied water deficit, S3 - Irrigation with controlled deficit in the vegetative stage, S4 - Irrigation with controlled deficit in the flowering and fruiting stages and S5 - Irrigation with controlled deficit in the maturation and harvest stages), with water deficit established at 50% of crop evapotranspiration, and use of hydrogel (WiH - With hydrogel, WoH - Without hydrogel), with four replicates, and with three plants per plot. The variables tested were: total number of flowers and fruits, total fruit weight and canopy thermal index. At 60 days after transplanting, the regular deficit irrigation and irrigation with controlled water deficit in the flowering, without hydrogel, showed the highest means of thermal index (0.98, 1.03 and 0.70 °C, respectively) and lowest leaf water potential (-0.70, -0.48 and -0.50 MPa, respectively). The thermal index obtained by thermographic images is viable for determining the effects of water deficit on cherry tomato.

Published: February 2025

ABSTRACT Several agro-industrial residues can be utilized for the extraction of sugars through chemical reactions. This study evaluated the extraction of total sugars and reducing sugars from banana (Musa paradisiaca) and orange (Citrus sinensis) peel residues using acid hydrolysis. It also investigated if there is a difference between the concentration of sugars present, and analyzed the effect of different sulfuric acid concentrations and reaction times. A completely randomized 2 × 4 × 2 experimental design was used to evaluate two types of waste, exposed to four concentrations of sulfuric acid (4, 6, 8 and 10% V/V) at reaction times of 2 and 4 hours. This amounted to 16 treatments with three repetitions. The experimental units consisted of borosilicate glass flasks, half submerged in a bath of vegetable oil and assembled in a rapid cooling tower from which the analyzed glucose syrups were obtained. The orange peel residues showed the highest values of reducing sugar extraction with 8% sulfuric acid concentration, presenting mean of 16.46 mg L-1 ± SE = 0.591 and optimal hydrolysis reaction time of 2 hours. With 4 hours reaction time, the extraction of reducing sugars was higher in orange peel residues compared to banana peel residues. Both residues proved to be suitable for sugar extraction, presenting a valuable opportunity for utilization in regions where they are readily available. They can be employed in fermentation processes for bioethanol production.

ABSTRACT Controlled germination is a simple low-cost procedure to improve the nutritional, functional and sensory quality of seeds intended for food. Germination conditions directly influence the final composition of the sprout, being mainly a function of the process time. Thus, the aim was to examine the effects of germination periods on the nutritional properties of lima bean seeds of the varieties ‘Orelha-de-Vó Preta’, ‘Raio-de-Sol’, ‘Branca’, and ‘Raio-de-Sol Grande’. The water content, proteins, starch, total and reducing sugars, total phenolic compounds, tannins, flavonoids, and anthocyanins were evaluated at times 0, 24, 48, 72, and 96 hours. The data was processed in a completely randomized design and arranged in a factorial scheme (4 × 5), with three replicates. The germination process increased the protein content and reduced the starch content, promoting a partial increase in reducing sugars and total sugars. The total phenolic compounds, tannins, flavonoids, and anthocyanins increased with the process time, reaching absolute maximum values between 72 and 96 hours. The variety ‘Orelha-de-Vó Preta’ presented the highest values of total phenolic compounds and anthocyanins; the flavonoid content was higher in ‘Orelha-de-Vó Preta’ and ‘Raio-de-Sol Grande’, while the variety ‘Branca’ presented the highest of total tannins content. Therefore, it is concluded that germination has proven to be a process capable of enhancing the nutritional and functional composition of lima beans.

ABSTRACT The use of efficient, fast, and low-cost tests is essential in seed quality control programs. The objective of this study was to adapt exudate pH and primary root emergence tests for coriander (Coriandrum sativum) seeds. A completely randomized experimental design was used, with four replications of 50 seeds. Four coriander (C. sativum cv. Super Verdão) seed batches were evaluated for moisture content, first count, germination, emergence, emergence speed index, seedling total dry weight, and subjected to accelerated aging and tetrazolium tests. Exudate pH tests were conducted using soaking times of 30, 60, 90, and 120 minutes at 20, 25, and 30 °C. Primary root emergence tests were conducted at 20, 25, and 30 °C, starting observations 24 hours after the beginning of the test at 12-hour intervals and concluding after 120 hours. The exudate pH test at 20 °C for 30 minutes classified the batches similarly to the germination test, but differently from vigor tests. The primary root emergence test conducted at 20 °C, with evaluation after 60 hours, effectively classifies the vigor of coriander seed batches.

ABSTRACT Introduction: Spirituality, by providing positive coping or religious/spiritual coping, mobilizes resilience, a positive worldview, and a support network, thereby promoting physical and mental health. Objective: To identify spiritual religious coping by analyzing the association between sociodemographic/educational variables and the level of spiritual guidance among health residents in Recife. Method: This was a cross-sectional, exploratory, and quantitative analytical study. Spirituality was assessed using the Spirituality Self Rating Scale (SSRS), and religious coping was measured by the Brief Religious/Spiritual Coping Scale (RSC-Brief). The collected data were analyzed using Stata 12.1 software, with crude and adjusted prevalence ratios (PR) estimated, and 95% confidence intervals (CI). The study was approved by the Ethics Committee of IMIP under CAAE N. 42807221.2.0000.5201. Result: Of the 107 participants, the majority were aged between 21 and 25 years (45.8%), female (79.4%), enrolled in multidisciplinary residency programs (50.5%), and attending the first year of their course (89.7%). Positive religious coping was identified as medium, high, or very high in 69.2% of participants, while low or no negative religious coping was found in 93.4%, and medium/high spiritual guidance in 57%. Residents with Lato Sensu postgraduate qualifications showed a 40% higher prevalence ratio for having a medium/high level of spiritual guidance compared to those with only undergraduate education, and this ratio was 46% higher in the nursing area when compared to the other fields. Conclusion: Spirituality and religious coping were more prevalent among nursing professionals and those with higher academic qualifications.

Experimentalismo transfeminista e análise audiovisual implicada: nos entramados de Jup do Bairro
Authors: Rocha Rose de Melo
Published: February 2025

Resumo Apresento neste artigo uma reflexão de cunho interdisciplinar sobre a multiartista paulistana Jup do Bairro, problematizando núcleos expresivos de sua obra audiovisual e a situando no campo da produção experimental transfeminista. A partir daí, pergunto: quais as características e dimensões estéticas e políticas dessa expressividade? Para responder a nossa problemática mobilizamos a perspectiva artivista, as dinâmicas das culturas juvenis urbanas, e a hipótese de um acionamento biocultural atinente ao espectro artístico configurado por Jup enquanto jovem trans preta. A análise de três videoclipes da artista contempla perspectivas cartográficas e comunicacionais, e considera as redes de afetos articuladas na produção, circulação e recepção da obra artística em questão, enquanto potência contranarrativa. Conclui-se que o experimentalismo transfeminista de Jup conforma ações de resistência e existência, enfrentando normatividades e segregações raciais, de gênero e sexualidade, e apresentando uma nova gramática e uma inteligibilidade outra sobre sonoridades, imagens, corpos e cidades.

Published: February 2025

Resumo Nos últimos anos, no Brasil, um fenômeno que tem atraído atenção de um público mais amplo é a “destransição” de pessoas travestis e transexuais. No país, as redes sociais tornaram-se uma arena na qual tais processos circulam e expõem reações de diversos atores sociais, que dizem respeito a gramáticas morais, religiosas e políticas no que tange a concepções de gênero. Abordaremos essa problemática a partir do caso de destransição pública, com ampla repercussão na mídia, do influenciador digital Manuel, anteriormente conhecido nas mídias sociais como “Catty Lares”, que em abril de 2023 anunciou ter se “casado com Jesus”. Buscamos mapear as narrativas que se desenrolam nas redes sociais a partir desse fato e de que maneiras estas se constituem como discursos morais, religiosos e políticos que podem reforçar ou tensionar noções de gênero. Nosso objetivo é explorar, a partir desta controvérsia, as relações entre “destransição”, religião, cisgeneridade e homotransfobia.

Published: February 2025

Abstract This study investigates the effectiveness of employing Planar Transmission Lines (PTL) with stubs to determine the water content in transformer oils. The research aims to elucidate how transmission responses along the line can provide valuable patterns for oil characterization. Notable results were achieved, particularly in identifying representative frequencies for each range of S21 scattering parameters, enabling the derivation of well-fitted linear expressions for the data. These findings suggest promising potential for the practical application of this approach. This study contributes not only to the understanding of the proposed technique but also to the stimulation of subsequent research aiming to enhance and consolidate this analytical methodology.

Illustrated type catalogue of marine Isopoda (Crustacea: Peracarida) from the Museu Nacional/UFRJ, Brazil
Authors: Serejo Cristiana S. , Fernandes Agatha C. S.
Published: February 2025

Abstract The Crustacea Collection of the Museu Nacional/UFRJ is one of the most relevant and representative of the Brazilian crustacean fauna. Currently, it comprises around 31,000 registered lots, of which 5,435 lots belong to the order Isopoda. This paper provides an illustrated catalog of two topotype species and 34 type species of marine isopods deposited at the Crustacea Collection of Museu Nacional/UFRJ, distributed in 22 genera, 12 families and six suborders. This collection is represented by 27 lots of holotypes, 81 lots of paratypes (15 named as allotypes), and two topotypes, published mainly by authors such as Alceu Lemos de Castro and Idalina Brasil-Lima, former researchers of Museu Nacional in the 20th century. The two topotypes species were included in the catalog as they came from the same collection event as the holotype and have been historically kept as type material within the museum collection. In general, the type materials are in good condition, however, the holotype of Robustura parvula (Albuquerque, 1978) and all type material of Pseudione serejoae Brito, Cardoso and Boyko, 2018 have been lost and await the designation of neotypes. Furthermore, this catalog is part of a larger project, in an effort to improve the curation and digitization of the museum´s type collection data. By photographing the specimens and digitizing the collection specimens´ labels, we expect to improve internal management and offer free access to the data, so as to preserve and promote the museum´s collections, which guard important and unique information on world biodiversity.
Impact of thermal variation on the naupliar development of the copepod Apocyclops spartinus (Ruber, 1968) (Copepoda: Cyclopidae), under controlled conditions

Published: February 2025

ABSTRACT Apocyclops spartinus is a subtropical resilient copepod from impacted Peruvian wetlands, widely used for marine fish larviculture and conserved as a strain at Instituto del Mar del Peru - IMARPE. This study was conducted to test the effects of three thermal conditions (16, 20 and 24 ºC) on the individual growth of conditioned nauplii. Sub-stage growth rates, three growth models and three growth rate-dependent models were evaluated. Considering these previous experiments, naupliar growth retardation and mortality were evaluated for cold shock stress (8 ºC lower). Results indicated a progressive increase in development time by reducing temperature from 24 to 20 ºC (1.75 times) and 20 to 16 ºC (4 times). Growth rates showed a tendency to decrease, prior to metamorphosis and independent of temperature. Gompertz was the best growth model by describing sigmoidal tendency of naupliar development. Arrhenius was the best growth rate-dependent model but slightly better supported than a simple allometric model. Naupliar growth retardation was noted in nauplii that were initially hatched at 24 ºC and then swiftly transferred to a culture at 16 ºC. This cold shock stress resulted in high mortality from day four onwards. In summary, A. spartinus nauplii exhibit potential as a live food source and it is recommended that targeted thermal treatments be employed to extend the time of optimal nauplii size and thereby enhance culture techniques of this species.

La investigación utilizó una metodología cualitativa con un enfoque fenomenológico y un muestreo no probabilístico. La información fue recolectada mediante la aplicación de entrevistas en profundidad a terapeutas ocupacionales que desempeñan sus funciones en una unidad de cuidados críticos. Diálogos de los cuales emergieron textos que fueron codificados, identificándose a partir de ellos, temas, categorías y subcategorías que permitieron interpretar los datos recolectados, desde una perspectiva hermenéutica. Entre los resultados más relevantes obtenidos se puede evidenciar la importancia atribuida por terapeutas ocupacionales de una unidad de cuidados críticos, a la implementación del razonamiento narrativo y las estrategias que consideran la creación de cuentos y el relato de historias en los procesos de evaluación, intervención y recuperación de pacientes con enfermedades críticas. Esto, porque el razonamiento narrativo facilita el proceso terapéutico al permitir a los terapeutas ocupacionales comprender el significado de la enfermedad y la influencia del entorno, fundamentando las acciones terapéuticas utilizadas en la evaluación e intervención dentro de estas unidades. Como conclusión, es posible establecer que la aplicación del razonamiento narrativo y sus dos vertientes: la narración de cuentos y la creación de historias son esenciales para la evaluación e intervención de pacientes críticos. Pues rescata la experiencia del paciente, permitiendo la expresión de la cotidianidad, reduciendo las barreras socioculturales en un contexto biomédico.
Nonlinear seismic analysis of a reinforced concrete building for Brazilian conditions and standards
Authors: Cóco José Vittor Siqueira , Schulz Mauro
Published: February 2025

Abstract This paper presents a methodology for the nonlinear analysis of reinforced concrete beam structures subjected to Brazilian seismic actions and safety standards. Specific constitutive relations for concrete and steel are employed to account for cyclic loading. The implicit time integration algorithm ensures the equilibrium conditions at the end of each time step. Model results are compared with experimental data from a test structure, confirming the model's applicability. An additional example evaluates a typical structure in Rio Branco, AC, Brazil, using the Brazilian standard ABNT NBR 15421:2023 and other applicable Brazilian codes. The methodology provides insights into structural performance during an earthquake, including stress, strain, and nodal displacement histories. The results indicate that the implemented methodology is a viable option for the seismic evaluation of reinforced concrete buildings in Brazil.

Published: February 2025

Abstract Species of the chewing louse genus Neopsittaconirmus Conci, 1942 are host-specific parasites on Old World and Australasian parrots (Psittaciformes), infesting both wild and captive birds. Despite veterinarian practices that attempt to eliminate parasites from captive hosts, two species, Neopsittaconirmus gracilis Guimarães, 1974 and Neopsittaconirmus vendulae Sychra, 2006, frequently infest captive birds, not only their regular natural hosts, but also other species that are not naturally parasitized. Here we report and discuss additional records of these two species of lice from captive parrots in Brazil, Australia, England, Réunion and the United States of America.
Non-native golden dorado, Salminus brasiliensis (Characiformes: Bryconidae): A threat to biodiversity in the Preguiças River, Northeastern Brazil
Authors: Aguiar-Santos Jamerson , Meneses Mairton Batista
Published: February 2025

ABSTRACT The emergence of non-native species as a threat to local biodiversity is a pressing concern that warrants immediate attention. Our study reports the first record of the non-native fish golden dorado, Salminus brasiliensis, for the Preguiças River Basin, Maranhão State, Northeastern Brazil, near the Parque Nacional dos Lençóis Maranhenses (PNLM). This discovery occurred when a single adult, measuring 77 cm in total length, was captured by artisanal fishers using gillnets in January 2024. This finding underscores the importance of ongoing monitoring efforts focused on the ichthyofauna of the Preguiças River Basin: the tributaries of the lower portion of the basin are located within and at the border of the PNLM area. Such monitoring initiatives are essential for comprehending the distribution range of S. brasiliensis and evaluating its potential impacts on local native freshwater species.
Comparação dos impactos cognitivos do uso do Instagram versus TikTok entre adolescentes de diferentes níveis socioeconômicos
Authors: Lacerda Giovana , Ramalho Ana Claudia
Published: February 2025

A utilização de redes sociais vem aumentando significativamente, sendo o Brasil o terceiro país com maior uso diário de redes sociais (10 horas e 35 minutos). As redes sociais são responsáveis pela liberação instantânea de dopamina, o que perpetua a necessidade de utilização da rede para manter esse alto nível de satisfação. Assim, ao interromper a utilização das redes, o indivíduo sofre uma imediata redução de dopamina em sua circulação podendo trazer irritabilidade e tristeza. Por esse motivo, o estudo visa analisar os impactos do Instagram e do TikTok nas funções cognitivas  (atenção e memória), na fase da adolescência. Os objetivos deste estudo são analisar o impacto cognitivo do Instagram e do TikTok, contrastar os resultados em diferentes níveis socioeconômicos e entre diferentes comportamentos dos jovens na rede social. O estudo consiste de 2 etapas: 1- aplicação de um questionário, testes de atenção e memória, e 2- os participantes serão divididos em 2 grupos: Grupo 1: vão reduzir Instagram, grupo 2: vão reduzir TikTok, por 4 semanas, e farão o questionário e testes de atenção e memória antes e após o período de redução. O questionário aplicado consiste de itens sobre utilização das redes sociais, teste de atenção e teste de memória. Resultados: 70% dos jovens que utilizavam redes sociais imediatamente antes de dormir sentiam irritação frequentemente e 68,75% indicaram dificuldade de dormir. E, dos usuários das redes que tinham média de uso diária de 3-5 horas, 50% destes, dos que utilizavam Instagram, e 35% do TikTok tinham as notas escolares de 8.0 ou acima. A  média diária de estudos para 50% dos adolescentes de ambos os grupos foi maior de 4 horas. Conclusão: que há uma similaridade entre o TikTok e o Instagram no que tange à influência na rotina de estudos, e que estas duas redes não estão associadas diretamente ao desempenho escolar. Além disso, percebe-se uma influência comportamental da utilização de redes sociais muito próxima à hora do sono.

Conclui-se que as metodologias ativas são eficazes para dinamizar o ensino de temas complexos, promovendo um aprendizado mais significativo e alinhado às necessidades pedagógicas contemporâneas.
Financialisation of the Peripheral State: the Role of Currency and Sovereign Debt Hierarchies
Authors: De Souza Cinthia
Published: February 2025

This paper explores the concept and manifestations of state financialization, emphasizing its particularities in peripheral economies. While the state actively fosters financial market development and relies on it for economic policy execution, it is also disciplined by these markets, reinforcing neoliberal constraints that limit policy autonomy and expand financial power. In peripheral states, financialization is deeply shaped by currency and sovereign debt international hierarchies. This mutual dependence creates a contradiction: financial deepening provides risk management tools but simultaneously strengthens global financial hierarchies, to the detriment of peripheral countries.

A semiose é um processo emergente: sincrônico e holístico, ou diacrônico e transformacional?
Authors: Atã Pedro , Queiroz João
Published: February 2025

A emergência está relacionada à irredutibilidade, e à imprevisibilidade, indicando que as propriedades de um sistema não podem ser deduzidas de suas partes. No escopo da filosofia do signo de C.S.Peirce, a noção de emergência fornece uma compreensão sobre como processos semióticos são compostos de interações materiais entre organismos, artefatos e ambientes, e ainda assim possuem propriedades únicas. Ela pode ser diacrônica, quando um domínio base transforma-se em um domínio emergente ao longo do tempo, ou sincrônica, onde bases e emergentes coexistem temporalmente com diferentes propriedades qualitativas. Ela pode ser fraca, explicando epistemologicamente os fenômenos, ou forte, implicando numa nova ontologia. No emergentismo processualista, são priorizadas relações e organizações sobre substâncias. A descrição de Peirce dos fenômenos como relações triádicas reflete precisamente essa visão, com ênfase na complexidade e na dinamicidade da semiose. O processo não-linear de produção de significado sugere que o significado de um signo é continuamente formado por complexos entrelaçamentos de interações passadas e futuras, generalizadas na forma de hábitos e antecipações.
Face mask chips-reinforced sands under monotonic and cyclic torsional shearing
Authors: He Shao-Heng , Yin Zhen-Yu , Ibraim Erdin , Ding Zhi
Published: February 2025

In an effort to enhance engineering infrastructure and reduce environmental waste, the use of COVID-19 face-mask chips (FMC) in sand reinforcement is experimentally explored through drained hollow cylinder torsional shear tests, including monotonic stress paths with different fixed orientation of the principal stress axes and cyclic tests with traffic load and pure principal stress rotation. Fujian sand and Hong Kong CDG sand were used. The monotonic test results indicate that both sands exhibit a strong strength anisotropy, however, although the addition of FMC increases the peak stress ratio to failure of the composites for all tests, the strength anisotropy trends with ασ are not changed. Results from x-Ray CT scanning analyses conducted on FMC-reinforced and unreinforced cylinder sand specimens supported the interpretation of experimental data. Furthermore, the inclusion of FMC induces increased plastic deformation under cyclic loads in all tests, however, the level of these plastic strains is sand-type and stress-level dependent. It was also observed that both sands exhibit non-coaxial characteristics, but the presence of FMC inclusions do not change the non-coaxial trends observed for the pure sands.

Decoding Equity Market Reactions to Macroeconomic News
Authors: Modugno Michele , Palazzo Berardino
Published: February 2025

The equity market’s reaction to macroeconomic news is consistent with the propagation of news into the real economy. We embody all the macro news in an activity news index and a price news index that together explain 34% of the quarterly stock price returns variation. When those indexes capture a stream of favorable macroeconomic surprises, publicly traded firms experience increases in revenues, profitability, financing, and investment activities. The firm-level results
lead up to an expansion of the real side of the whole U.S. economy. Our findings, taken together, show that stock prices’ reactions to macro news have a strong association with firm-level and economy-wide growth.

Obesity, being a global epidemic of the 21st century, increases the likelihood of various diseases and conditions that are associated with increased mortality. Given the risks associated with obesity throughout life, identifying early predictors of its development is a priority task of prevention. Objective. Assessment of the prognostic significance of laboratory parameters, functional tests and instrumental examination data for the early diagnosis of obesity and associated metabolic disorders. Material and methods. The studies were conducted at the Scientific and Clinical Center 1 of the B.V. Petrovsky Russian Scientific Center of Surgery with the participation of 77 patients (43 men and 34 women) aged 33 to 65 years. After signing voluntary informed consent for a special study with the processing of their personal data, all patients underwent a comprehensive clinical, laboratory and functional examination. The study design provided for a three-time examination of patients with an interval of 6 and 12 months. To search for predictors of early diagnosis of obesity and metabolic disorders, we used an algorithm for constructing a mathematical model of multiple regression. The dynamics of the body mass index and the insulin resistance index served as the resulting feature. Results. To build a mathematical predictive model, a matrix of independent variables was formed, including parameters characterizing the biochemical status of patients, the severity of systemic inflammation, body composition, as well as arterial stiffness and vascular condition based on the results of ultrasound duplex scanning of the brachiocephalic arteries. The choice of the most informative set of independent variables that act as predictors provides for achieving the maximum additive effect in explaining the variance of the resulting feature. The construction of the actual mathematical multiple regression model was based on the results of the selection of independent factors carried out using the method of sequential hypothesis testing. As a result of applying the algorithm of sequential hypothesis testing, three independent variables (predictors) were identified to predict the degree of BMI increase and four variables to predict the development of metabolic disorders. The accuracy of the developed model, verified at the final stage of the study, showed its high information content. Conclusion. Two clusters of predictors were identified: the cluster of predictors for the risk of obesity development includes the systemic inflammatory response index, the triglyceride-glucose index and the blood leptin level. The cluster of biomarkers of metabolic disorders consists of the atherogenicity coefficient, the blood malondialdehyde level, the systemic inflammation index and the body roundness index.
AN APPRAISAL OF SELECTED SALIENT HUMAN RIGHTS BEING IMPACTED AND ALTERED BY ARTIFICIAL INTELLIGENCE (AI)
Authors: Thupane J Kgoale  , Kola O Odeku
Published: February 2025

With the emergence and broad deployment of Artificial Intelligence (AI) in all sectors of the economy and human endeavours, this article accentuates the possibility that some fundamental human rights (guaranteed by most civilised nations) will be impacted and altered. To this end, the article appraises selected salient human rights being impacted by the deployment of AI, and which violate protected and guaranteed human rights, raising major concerns. The article assesses the theoretical grounding of human-rights law and its catalytic role in informing and shaping the emergence of new fundamental rights. Equally important, the article delves into pertinent legal issues emanating from the use of AI technologies and their potential threats to vulnerable new rights. While AI promises a significant positive impact on the economy and human development, there is a need to address pertinent concerns about the manner in which AI could impact existing human rights, and ultimately alter the form and content of these rights, resulting in the emergence of new fundamental rights.
The Creation of the Legal Services Ombud – How to Make It Effective
Authors: Basil Mashabane
Published: February 2025

The office of the Legal Services Ombud is a new creation regulating the practice of law and the legal profession under the Legal Practice Act, 2014. The purpose of this note is to provide a discussion and analysis of the purpose and nature of the establishment of the Legal Services Ombud. The note delves into a comprehensive discussion of the meaning of “ombudsman” as a concept and the relationship this office has with the existing Legal Practice Council, whose main purpose is to regulate the conduct of legal practitioners, among other functions. The note seeks to draw a distinction between the Council’s role and the more comprehensive role of the Legal Services Ombud who must ensure that there is at all times, fairness and justice in how legal services are provided and that regulatory bodies (such as the Legal Practice Council) comply with these principles when their members render legal services to the public. The note also discusses whether the Legal Services Ombud is empowered to make binding rulings in the same manner as the Public Protector’s rulings, for instance, are seen and viewed as binding. Several conclusions are reached on this point in the note. It is argued in conclusion that positive steps must be taken to ensure that the work of the Legal Services Ombud is known, that the office is properly resourced to perform its functions in terms of the Legal Practice Act, and that sufficient clarity is provided on whether Ombud rulings are binding.
THE IMPACT OF ARTIFICIAL INTELLIGENCE ON THE LAW OF DELICT AND PRODUCT LIABILITY
Authors: Franaaz Khan
Published: February 2025

An enquiry into negligence involves evaluating a defendant’s conduct according to a standard that is acceptable to society. This standard is expressed with reference to a fictitious ‘reasonable person’ that represents society’s expectation of adequate and reasonable conduct in the law of delict. It represents an objective standard that all legal subjects must adhere to by paying sufficient attention to ensure that their conduct is in line with the standard of care that society expects.  However, this test of negligence in delict would in the near future require reform as there has been the new era of Artificial Intelligence (AI) that has legal implications. AI a term that is unpacked further in this article has seen it already diagnosing diseases, drafting legal contracts, and providing different levels of service. What happens in instances where these AI systems cause harm? How should South African law respond to accidents caused by AI? It is acknowledged that South Africa has an existing body of law in delict that deals with injury and harm. It provides a mechanism of compensation for an aggrieved party. Delict involves the standard of negligence in certain cases and that is pinned on a reasonable man test. However, would this test be the best fit given the changes in law? If an AI causes harm or damage the standard of the hypothetical reasonable man would not suffice. In South Africa, AI and the development of computer systems to perform tasks usually requiring human intelligence is progressing. However, as AI improves our everyday life, it also raises human anxiety and concern. The law needs to play catch up to this rapid and growing change in technology. In South Africa there is no legislation dealing specifically with AI and its legal issues that follow. Given the context that the discussion of AI and the law is a mammoth task to undertake, this note focuses only on the aspect of the reasonable man test in the law of delict and how the law can adapt or modify itself in respect of developing AI and cases of harm that are caused by an AI system in delict.
The note firstly examines the historical reasonable man test in South Africa and further unpacks the concept of AI. The note further examines and discusses the implications that AI has in respect of delict. The current legislative framework in South Africa is highlighted. In addition, this note examines the international changes made in respect of delict or tort law in respect of AI. Finally, the note provides recommendations as to how South Africa can position itself in respect of delict and AI.
