Swimming in the desert? The role of environment in motion verb acquisition
Authors: Benjamin Alice , Harrigan Kaitlyn
Published: May 2023

Any event includes countless components, giving the learner many possible options in mapping verb meanings. Previous research demonstrates that children are sensitive to the distribution of motion verbs in their language, mapping ambiguous verb-event pairings to manner if their language has more manner verbs, like English, and path if their language has more path verbs, like Spanish. Previous work also demonstrates that children have some sensitivity visual components, such an event’s location, when they are learning motion verbs. Our study explores how the learner weighs components of visual scene against the distributional factors present in their language. Like previous studies, we find that English-learning children are better at encoding manner than path information. Additionally, we build on previous work on motion verb acquisition, showing that children are differentially influenced by different kinds of background environments.

La comercialización de vehículos eléctricos (EV) demanda mayores rendimientos de las baterías recargables. Las evaluaciones precisas del estado de salud (SOH) y la vida útil restante (RUL) de las baterías son importantes para indicar el estado de la batería y garantizar la seguridad de los vehículos eléctricos. Sin embargo, las precisiones de los modelos de degradación de la capacidad de la batería existentes no son suficientes para describir los estados de la batería bajo los impactos complicados de los entornos de uso. Varias condiciones de operación harán que el modelado de degradación sea más desafiante y difícil, por ejemplo, las diferentes tasas de descarga y la carga y descarga discontinua pueden influir en las tendencias de degradación de la capacidad de las baterías. Para abordar los problemas anteriores, se proponen respectivamente dos modelos de degradación estadística para implementar pronósticos de batería en diferentes condiciones de uso basados en el conocimiento de big data y ciencia de datos. Los resultados muestran que los métodos propuestos superan muchos trabajos existentes.
Best Practice of Striving Energy Sustainability in a Hot Press Machine for Clutch Facing Manufacture

Published: May 2023

A facing clutch manufacturer in Surabaya, Indonesia, PT. X uses 20 hot press machines to produce the facings. The required heating process is provided by heat transfer oil (HTO), which is heated by natural gas burned in a heater. PT. X wants to reduce its natural gas consumption. The assessment started with checking the insulation on the piping system, measuring the temperature in the hot press machines, and measuring the HTO flow rate. The insulation in the piping system is in good condition. From the measurement, it was found that the HTO flow rate is adequate and fits the need of the heating process. Another finding is that the surface temperature of the lower plate in shaft no. 4 is the lowest than in the other shafts. The existing (asbestos) insulation from the lower bed in shaft no 4 to the hydraulic component is only 3 mm thick. This is not enough to prevent heat loss from the bed in shaft no. 4. The new 18-mm asbestos replaced the old asbestos. The replacement shows that the temperature at the mold surface at shaft no. 4 increased from 162.6°C to 170.9°C on average for MC-02 and from 166.7°C to 173.1°C on average for MC-03. Another achievement obtained is that the natural gas consumption was reduced by around 7.3% or 39 MMBtu/month, or equivalent to reducing 0.312 metric tons of CO2 per month. This is a simple effort to use less energy to protect our environment.

Published: May 2023

The present study investigated the performance of thermal arch plasma suction downdraft gasification which utilizing pelletized empty fruit bunch as a feedstock in producing syngas with high thermochemical conversion efficiency. Gasifying medium of air was used in this system. Syngas produced was evaluated and measured in terms of gas composition, carbon conversion efficiency, cold gas efficiency, syngas yield and calorific value. The effect of different equivalence ratio ranged from 0.18 to 0.46 was also evaluated. The results reported that syngas produced contained higher CO of 14.2 vol% at higher equivalent ratio, 0.42. In contrast to H2 content, higher composition of 9.92 vol% was produced at lower equivalent ratio, 0.18. HHV and CGE value was higher at equivalent ratio of 0.36 which correspond to the balanced constituent of CO, H2 and CH4 at this condition. CCE and syngas yield was maximum at higher equivalent ratio of 0.46 due to higher production of CO from carbon elements. The results of the present study provided a useful data and guideline of equivalent ratio range for operational of plasma downdraft reactor.
Effect of the Catalyst Shapes and the Packed Bed Structure on the Efficiency of Steam Methane Reforming
Authors: Ravil Mustafin  , Igor Karpilov
Published: May 2023

One of the promising technologies for on-board hydrogen production is methane steam reforming in reactor with packed bed. The study of the effect of various catalytic packing arrangements on the steam methane reforming process is of considerable interest. The present article analyses the influence of catalyst shapes and packing arrangement on steam methane reforming reactions efficiency. The reformer tube contains several packings with a changing relative position; additionally, two forms of catalysts, a ball and a cylinder, are also used. The pressure drop depending on the packing location, methane conversion and hydrogen yield were analysed. It was found that the packing arrangement with spacing allows better distribution of the supplied heat. Due to the distance between the packing sections flow becomes more turbulent after each section, which intensifies the heat transfer and mixing of the mixture. The highest hydrogen yield is observed on catalytic packings located at a distance of 40 mm from each other and consisting of cylindrical catalysts. The most uniform pressure drop occurs at a packing arrangement without spacing. The increase in methane conversion observed with the increment in spacing distance, but the difference is insignificant. Therefore, the arrangement of catalysts with spacing can be used for the improvement of steam methane reforming process.

Authors: PEHLİVANOĞLU Berkay Eren
Published: May 2023

Kayropraktik uygulamalar, kayropraktik mesleği kurulduğundan beri özellikle omurga üzerine odaklanarak gerçekleştirilen manipülatif uygulamalardan temel alır. Zaman içerisinde pek çok farklı tekniğin gelişerek meslek içerisinde ayrı kollar oluşturması mesleğin sürekli dinamik kalarak kendini yenilemesi zorunluluğunu ortaya çıkarmıştır. Bununla birlikte uygulamaların hemen hepsi belli başlı teknikler etrafında gerçekleştirilmektedir. Ancak aynı şekilde hemen hemen tüm tekniklerin uygulanması esnasında klinisyenin deneyimi ve mesleki becerisi ana rol üstlenmektedir. Bu da uygulamaların başarı oranı ve standardizasyon hakkında bazı soruları akıllara getirmektedir. İşte bu noktada kayropraktik uygulamaların belirli standartlarda gerçekleştirilebilmesi adına bazı cihazların geliştirilmesi gerekliliği ortaya çıkmıştır. Enstrüman Destekli Kayropraktik Spinal Manipülasyon Uygulamalarının odak noktası; belirli bir hızda ve belirli bir kuvvette vuruşu standart hale getiren cihazların klinisyenin deneyim ve becerisine olan ihtiyacı azaltarak hastaya uygulama yapılabilmesini olası hale getirmektir. Uygulama esnasında ortaya çıkabilecek komplikasyonların da standardizasyonun sağlanması ile elimine edilebileceği düşüncesi klinisyenler arasında yaygın olarak hâkimdir. Farklı markalar tarafından bu ana fikir etrafında üretilen cihazlar şuan hali hazırda satışa sunulmuş durumdadır. Tüm bu cihazların farklılıkları olsa da hepsi yukarıda bahsedilen amaç etrafında üretilerek klinisyenlere sunulmaktadır. Bahsedilen cihazların tümü başlık kısmında belirli bir salınım aralığı olan ve içerisindeki çeşitli enerji depolamaya yarayan mekanizmaların depoladıkları enerjiyi başlıkta hareket enerjisine dönüştüren kontrollü sistemlerden oluşmaktadır. Bu sistemlerde bir yayın sıkıştırılması, elektromanyetik enerjinin depolanarak aniden serbest bırakılması veya benzer mekanizmaların kullanıldığı sistemler yüksek hızlı düşük şiddetli kontrollü vuruşlar gerçekleştirebilmektedir. Bu da uygulayıcının belirli bir doğrultuda daha önceden belirlediği bir kuvveti omurga üzerine uygulamasına olanak tanımaktadır. Bu derlemenin ana amacı; Enstrüman Destekli Kayropraktik Spinal Manipülasyon Uygulamaları hakkında klinisyenlere bilgi vererek çok bilinmeyen omurga manipülasyon tekniklerinden birine ışık tutmaktır.

Exploring the Magnetic Field Geometry in NGC 891 with SOFIA/HAWC+
Authors: Kim Jin-Ah , Jones Terry Jay , Dowell C. Darren
Published: May 2023

Stratospheric Observatory For Infrared Astronomy/High-resolution Airborne Wideband Camera-plus 154 μm Far-Infrared polarimetry observations of the well-studied edge-on galaxy NGC 891 are analyzed and compared to simple disk models with ordered (planar) and turbulent magnetic fields. The overall low magnitude and the narrow dispersion of fractional polarization observed in the disk require significant turbulence and a large number of turbulent decorrelation cells along the line of sight through the plane. Higher surface brightness regions along the major axis to either side of the nucleus show a further reduction in polarization and are consistent with a view tangent to a spiral feature in our disk models. The nucleus also has a similar low polarization, and this is inconsistent with our model spiral galaxy where the ordered magnetic field component would be nearly perpendicular to the line of sight through the nucleus on an edge-on view. A model with a barred spiral morphology with a magnetic field geometry derived from radio synchrotron observations of face-on barred spirals fits the data much better. There is clear evidence for a vertical field extending into the halo from one location in the disk coincident with a polarization null point seen in near-infrared polarimetry, probably due to a blowout caused by star formation. Although our observations were capable of detecting a vertical magnetic field geometry elsewhere in the halo, no clear signature was found. A reduced polarization due to a mix of planar and vertical fields in the dusty regions of the halo best explains our observations, but unusually significant turbulence cannot be ruled out.
Compact Steep Spectrum Radio Sources with Enhanced Star Formation Are Smaller Than 10 kpc
Authors: Gordon Yjan A. , O’Dea Christopher P. , Baum Stefi A. , Bechtol Keith , Duggal Chetna , Ferguson Peter S.
Published: May 2023

Compact steep spectrum (CSS) radio sources are active galactic nuclei (AGN) that have radio jets propagating only on galactic scales, defined as having projected linear size (LS) of up to 20 kpc. CSS sources are generally hosted by massive early-type galaxies with little ongoing star formation; however, a small fraction are known to have enhanced star formation. Using archival data from the Faint Images of the Radio Sky at Twenty cm survey, the Very Large Array Sky Survey, and the Sloan Digital Sky Survey, we identify a volume-limited sample of 166 CSS sources at z < 0.2 with L
1.4 GHz > 1024 W Hz−1. Comparing the star formation rates and linear sizes of these CSS sources, we find that the ≈14% of CSS sources with specific star formation rates above 0.01 Gyr−1 all have LS < 10 kpc. We discuss the possible mechanisms driving this result, concluding that it is likely the excess star formation in these sources occurred in multiple bursts and ceased prior to the AGN jet being triggered.
Revision of Saalmulleria Mabille, 1891 (Lepidoptera, Metarbelidae) from Madagascar with the description of three new genera and fifteen new species
Authors: Lehmann Ingo , Dalsgaard Thure
Published: May 2023

This is the first publication of any genus of Metarbelidae Strand, 1909 for Madagascar since 1891. Here, the genus Saalmulleria Mabille, 1891 is revised comprising three species including descriptions of two new species. Three new genera are presented: first, an African-Madagascan sister genus-group, namely Shimbaniagen. nov. and Morondavaniagen. nov. The genus Morondavania is monotypic and comprises one new species, while Shimbania comprises 13 species, of which 11 species are new to science. Lebedodes wichgrafi (Grünberg, 1910) and L. durbanica Hampson, 1910 are treated as valid species and are moved to the new genus Shimbania. Secondly, the monotypic Eberhardfischeriagen. nov. that shares one synapomorphy with Saalmulleria. The species S. dubiefi (Viette, 1974) is excluded from Saalmulleria, since it most probably represents another undescribed genus. Species of Shimbania occur along the eastern coast of the African mainland up to about 540 km inland from the Indian Ocean, with one record from the Atlantic Ocean coast in Nigeria (Central Africa). The other three genera are endemic to Madagascar.

Dans le souci d’une histoire psychanalytique de la psychanalyse, nous prenons l’exemple du phénomène de scission pour tenter d’en saisir les enjeux autres que ceux, rapidement accolés, de dissidence . Soit faire la part entre des contenus manifestes, avancés comme faits, et les enjeux latents de ces scissions qui le plus souvent sont des processus de séparation-individuation par rapport à des situations vécues d’aliénation ou d’assujettissement, que ce soit en relation à un « maître » ou par rapport à un groupe institutionnel.

Published: May 2023

Edible insects are being considered as a potential sustainable food source to address global food security concerns and feed the world’s growing population. However, the quality and biological protein value of insects remain uncertain. This review analysedin vivo studies that evaluated edible insect consumption to clarify their potential as a high-quality protein source. Ten studies that evaluated protein quality in rats or mice were included, and most studies found weight gain similar to or greater than the control group. Food intake, net protein ratio, and biological value were also similar to those in the control group. However, true digestibility and protein efficiency ratio were generally lower in animals fed with insects, and higher nitrogen excretion was observed. The results of this systematic review were highly heterogeneous, and it cannot be concluded that insects have high protein quality, although positive results regarding weight gain and biological value were found.
Multi-mycotoxin production of cheese-derived fungal strainsin vitro and in cheese models
Authors: Ozturkoglu-Budak S. , Akal H.C. , Öztürk H.İ.
Published: May 2023

With regards to the cheese industry, fungal growth is a widespread problem and usually producers make effort to avoid fungal development due to mycotoxin formation which adversely affects human health, reduces product quality, and causes economic losses. However, some fungal strains are also used as secondary cultures to obtain developed sensory properties in cheese as a result of the enzymatic activities of these strains. Non-commercial strains isolated from mould-ripened cheeses and/or autochthonous strains that spontaneously grown on cheese have much greater effect on the acquisition of appreciated sensory and textural characteristics in cheese. Autochthon strains particularly ensure a characteristic aroma of traditional cheeses that are not commercially produced and can be a potential adjunct providing not produce mycotoxins. In this study, 14 differentPenicillium species previously isolated from traditional mould-ripened cheeses in cave were investigated for their mycotoxin production in bothin vitro culture medium andin situ in cheese model. The results revealed that although individual strains produced various and higher amounts of mycotoxins in the culture medium, the number of produced mycotoxins and the obtained values were determined quite low in the cheese medium. The outcomes of this study highlight the mycotoxin production of strains depends on the composition and structure of the food matrix that they integrated and many different factors, such as presence of free fatty acids, antimicrobial and antifungal compounds of lactic acid bacteria, lack of carbohydrate sources, and sulfhydryl-containing compounds, such as cysteine and glutathione. Therefore, the method used in this study has a potential to be a new solution in the industry to produce mould-ripened cheeses under controlled conditions without any potential health risk.
Reuse of Spanish Industrial Architecture From Tobacco Factories to Cultural and Public Spaces
Authors: Awad Tamar
Published: May 2023

The interest of the buildings analysed lies in the possibility of reusing and adapting them for other uses, as versatile examples that can be transformed into public, social and cultural centres. The time frame in which the study is framed is from the 17th century, with the creation of the first Tobacco Factory in Seville in 1620, to the present day, when the old factories and the urban environments in which they are located continue to be transformed. The enormous versatility of industrial architecture has allowed these factories to survive the passage of time and to adapt to changes in use. The reasons why they have been preserved are due to their dimensional characteristics and the fact that many of them were included in the historic city centres. These buildings can be considered as astute infrastructures because they are useful, sustainable, and functional.
Sustainability in Construction, Housing, and the City
Authors: Awad Tamar , Guardiola Jesús , Jiménez Mariano , González-Lezcano Roberto Alonso
Published: May 2023

Since the 1960s, a more rational and modern construction has been sought in line with industrialisation. In addition, due to the shortage of housing, professionals in the construction sector have been looking for solutions. The industrialisation of construction was first attempted after the Second World War through prefabrication. Today, it is moving towards more open concepts, making the industrial development of its products compatible with a construction that is still archaic and in need of updating. On the other hand, architects have reviewed the programmes and needs of users and citizens, in housing, workplaces, commerce, leisure and cities, and have proposed more contemporary solutions, with greater flexibility. Sustainability can be seen in a techno-biological environment, where artificial activity is integrated with the life and resources of the environment, in a new balanced ecological system. The methodology implemented is based on systems theory, according to tools specifically developed in construction, for proposals and designs around the industrialisation of housing.
Urban Health as a New Vector to Characterise Vulnerable Neighbourhoods
Authors: López Emilia Román , García Ester Higueras , Hernández Rafael Córdoba , Menéndez Elisa Pozo
Published: May 2023

For decades, public administrations have been working on rigorous analysis to identify and delimit vulnerable neighbourhoods in order to prioritize their regeneration and rehabilitation actions. The progress and improvements have been significant, mainly in Euskadi (Spain), thanks to an alignment of economic investment with an exhaustive knowledge based on the articulation of indicators that integrate social, economic, environmental, and urban data into a digital open access platform (GeoEuskadi). However, despite all these plans and actions, most vulnerable neighbourhoods continue to have these challenges. This situation has made the Government of Euskadi contract a pilot plan with the aim of establishing a new methodology to characterise vulnerable residential areas.

Authors: Demeter Marylee
Published: May 2023

Diversity, equity, and inclusion (DEI) has become a major focus in higher education in recent years. With increasing attention on equity and fairness, institutions of higher learning are implementing approaches to reviewing and revising curricula and assessments to ensure all students are equally prepared to succeed in their programs of study. The purpose of this chapter is to describe a mixed- methods exploratory approach to identify sources of inequities in a selection of objective and performance assessments as part of a larger project focused on reviewing a selection of courses for issues related to (DEI) attainment. Procedures and results are presented for assessments in four courses across four disciplines (general education, information technology, business, and health professions) along with recommended solutions to even the playing field for all students. A discussion of limitations and next steps to create access to equitable education and assessment opportunities closes this chapter.

Authors: Hannoun Abdelaziz , Chafiq Nadia , Raji Mohammed , Elkouali M’hamed , Razine Rachid
Published: May 2023

Introduction: In Morocco, the traditional media allows messages of non-scientific prescriptions for the treatment of diseases and statements criticizing doctors to pass, which are considered by doctors as defamation and attacks on the honor of the medical profession. The aim of this study was to analyze physicians’ perception in Morocco regarding health topics in the traditional media (TM).Methods: This is a descriptive transversal study of physicians practicing in Morocco. The data were collected through the use of a questionnaire that included questions on reliability, speed, up-to-dateness and influence of TM, also trust and interest in TM, and quantity, quality of health messages in TM.Results: A total of 417 physicians responded, among them 234 (56.1%) had little or no interest in health topics in TM; 248 (59.5%) considered the quantity of transmitted messages to be low; 234 (56.1%) considered that health messages in TM are of low quality; 248 (59.5%) had little or no trust in health topics in TM. Also, three quarters [314(75.3%)] of the physicians recognized a moderate to strong influence of TM on health behaviors.Conclusions: Our results show that physicians have a perception that seems negative towards TM. This may partially explain the chronic tension situation between physicians and journalists/media in Morocco. To better understand this situation and improve this relationship in favor of health promotion, it is necessary to conduct a research addressing the opinion of journalists and the propositions of solutions of both parties.

Fraud, corruption, misappropriation of public funds and general incompetence on the part of municipal managers and their staff have been the problems that have crippled most municipalities.Aim: To investigate the association between the municipal credit management policy, responsiveness and service delivery, within a Sedibeng district municipality.Methods: This study applied quantitative analysis. The primary data were collected from residents through a self-administered questionnaire. Statistical Package for the Social Sciences (SPSS) (Version 28) was applied to perform the descriptive analysis and correlational analysis.Results: Key findings of this study revealed a significant positive correlation between credit management and service provision. The relationship between the credit management policy, responsiveness to credit management and service delivery is substantial. Therefore, the quality of service delivery increases with improved credit management.Conclusion: The study showed that there is a significant connection between credit management, credit management responsiveness and service delivery.Contribution: Based on the findings, it was advised that the municipality should implement rebates and discounts for paying customers, constantly review crucial credit policies and ensure the provision of high-quality services. The study concluded that there is an association between credit management, responsiveness and service delivery.
The influence of fire presence and absence on grass species composition and species richness at Mountain Zebra National Park

Published: May 2023

It is well known that fire is a common driver in many biomes and it plays a vital role in maintaining ecosystem functioning in many South African biomes. This ecosystem process is an important determinant of plant community composition and diversity, and can result in changes in structural composition and ecosystem functioning. The main objectives of this study are to determine the influence of fire on grass species richness, diversity and composition in Mountain Zebra National Park. Using satellite imagery, the park’s fire history was determined between 2000 and 2020. Eighty plots (approximately 20 m × 20 m; 100 m apart) were laid out purposively across different fire regimes. There was no significant difference in both species richness and diversity in burned and unburned sites. However, there was a difference in species composition between burned and unburned sites and between different fire frequencies. The unburned site had higher moribund material and unpalatable grasses compared to the burned area.Conservation implications: The results of this study will help in the completion of the fire management plan for the park which will enable conservation managers to make better decisions with regard to fire management in mountainous grassland at Mountain Zebra National Park. Consequently, this will lead to improved veld condition and vegetation structure.
Perceptions of women enrolled in a cardiovascular disease screening and prevention in HIV study

Published: May 2023

Background: The ISCHeMiA (integration of cardiovascular disease screening and prevention in the human immunodeficiency virus [HIV] management plan for women of reproductive age) study is an ongoing, 3-year, prospective, quasi-experimental study comparing usual care to a primary health care intervention plan guided by the World Health Organization Package of Essential Non-Communicable (WHO-PEN) disease interventions. Sixty eight percent of women were overweight or obese at baseline in the ISCHeMiA study, many of whom reported nonadherence to interventions at 6 months post enrolment. This study explores the perceptions of women living with HIV (WHIV) towards their participation in the ISCHeMiA study to understand the barriers and facilitators to lifestyle modification interventions for cardiovascular disease (CVD) risk prevention.Methods: A qualitative enquiry using semistructured interviews was conducted with 30 overweight WHIV at one year post-enrolment in the WHO-PEN intervention arm of the ISCHeMiA study. Data were transcribed verbatim following the interviews and analysed using conventional content analysis.Results: Four major themes emerged from the data, namely perceived body image, benefits barriers and recommendations to improve adherence to WHO-PEN lifestyle modification management.Conclusion: Women in the ISCHeMiA study believed that HIV associated stigma hindered access to care. Financial limitations and the lack of social support posed barriers to adherence to programme participation. They were further challenged by poor body image perception. Participants believed that such interventions offered them hope and feelings of improved well-being. Women recommended that lifestyle modification interventions such as those studied in the ISCHeMiA study should include partners and family to improve adherence through social support.

Authors: Lamprecht Dirk J. , Martinson Neil , Variava Ebrahim
Published: May 2023

Background: HIV and AIDS continues to impose substantial healthcare challenges in sub-Saharan Africa, but there are limited local data comparing inpatient outcomes between people with HIV (PLWH) and those uninfected.Objectives: To compare cause-specific mortality among hospitalised adolescents and adults, stratified by HIV-serostatus.Method: A cross-sectional analysis was performed, analysing cause-specific inpatient mortality data and total admissions, from 01 January 2017 to 30 June 2020, at Tshepong Hospital, North West province, South Africa.Results: The overall inpatient mortality rate decreased from 14.5% (95% confidence interval [CI]: 13.4–16.0) in 2017, to 11.3% (95% CI: 10.6–11.9) in 2020; P  0.001. People living with HIV accounted for 53.9% (n = 2342) of inpatient deaths, 22.6% (n = 984) were HIV-seronegative patients and 23.5% (n = 1020) patients with unknown HIV-serostatus. People with HIV died at younger ages (median: 44 years, interquartile range [IQR]: 35.8–54.2) compared to HIV-seronegative inpatients (median: 64.4 years, IQR: 55.5–73.9); P  0.001. Leading causes of death were pneumonia (19.9%, n = 863), then pulmonary and extrapulmonary tuberculosis (15.0%, n = 654). People with HIV who had CD4+ counts 350 cells/mL or viral load ≥ 1000 copies/mL had increased risk of death from tuberculosis compared to virally suppressed patients (adjusted relative risk: 2.10 [95% CI: 1.44–3.04, P  0.009] and 1.56 [95% CI: 1.22–2.00, P  0.001]).Conclusion: Our study, conducted in a regional hospital in South Africa, showed PLWH had higher mortality rates and died at younger ages compared to HIV-seronegative patients.

Authors: De Wet Tessa , Rothmann Sebastiaan
Published: May 2023

Orientation: Education trends in Africa indicate that key ingredients for effective education are elusive, impacting the teachers who need to remain productive, motivated and healthy in this environment.Research purpose: Using machine learning active learning technology, the study aimed to review current literature related to the factors affecting the capabilities and functionings of secondary school teachers in sub-Saharan Africa (SSA).Motivation for the study: The Capability Approach (CA) provides a framework for studying the sustainable employability (SE) of teachers, including what they require to be able to convert valued opportunities into the needed achievements.Research approach/design and method: A systematic literature review was conducted following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, using Machine Learning Active Learning Technology. Eighty six articles from 14 SSA countries were included for analysis, prioritising articles in the South African context first.Main findings: Analysis identified four groupings of resources that are potentially useful or valuable, creating access or empowerment if utilised effectively, namely knowledge commodities, soft commodities, hard commodities, and organisational commodities. Sub-resources were also identified.Practical/managerial implications: This research would assist policy and decision-makers to focus their interventions in the most effective way to sustain productivity and well-being in the workplace. The resource groupings should be included in a model that focuses on enhancing secondary school teachers’ capabilities to promote their well-being and productivity.Contribution/value-add: This article provides new applied knowledge related to machine learning active learning technology as a methodology, and provides further insight into secondary school teacher employability.
