Frequency Analysis of KIC 1573174: Shedding Light on the Nature of HADS Stars
Authors: Lv Chenglong , Esamdin Ali , Pascual-Granado J. , Yang Taozhi , Shen Dongxiang
Published: June 2022

We propose that KIC 1573174 is a quadruple-mode δ Scuti star with pulsation amplitudes between those of the high-amplitude Delta Scuti star group and average low-amplitude pulsators. The radial modes detected in this star provide a unique opportunity to exploit asteroseismic techniques up to their limits. Detailed frequency analysis is given for the light curve from the Kepler mission. The variation of the light curve is dominated by the strongest mode with a frequency of F0 = 7.3975 day−1, as shown by Fourier analysis of long cadence data (Q1–Q17, spanning 1460 days), indicating that the target is a δ Scuti star. The other three independent modes with F1 = 9.4397 day−1, F2 = 12.1225 day−1, and F3 = 14.3577 day−1, have ratios of P
1/P
0, P
2/P
0, and P
3/P
0 estimated as 0.783, 0.610, and 0.515, which indicate that KIC 1573174 is a quadruple-mode δ Scuti star. A different approach has been used to determine the O − C through the study of phase modulation. The change of period (1/P)dP/dt is obtained resulting in −1.14 × 10−6 yr−1 and −4.48 × 10−6 yr−1 for F0 and F1 respectively. Based on frequency parameters (i.e., F0, F1, F2, and F3), a series of theoretical models were conducted by employing the stellar evolution code MESA. The ratio of observed f
1/f
2 is larger than that of the model, which may be caused by the rotation of the star. We suggest high-resolution spectral observation is highly desired in the future to further constrain models.

We report the results of spectroscopic and photometric observations of the emission-line object IRAS 07080+0605 carried out in 2004–2021. We found that the object is significantly underluminous for its spectroscopic properties (T
eff = 8500 ± 500 K,

log

g = 2.0 ± 0.5), if a strong visual attenuation by a factor of ∼43 found through the spectral energy distribution modeling is not taken into account. Visual brightness variations with a stable period of 190 days but a variable amplitude of ∼0.2 mag were found in the ASAS SN data and attributed to variable circumstellar extinction in the dusty disk. We also found that the observed behavior of IRAS 07080+0605 is similar to that of the protoplanetary nebula Red Rectangle. The dusty disk of IRAS 07080+0605 shows the presence of carbonaceous particles (∼10%–20% of the total dust content) and polycyclic aromatic hydrocarbon emission bands. However, IRAS 07080+0605 shows no obvious signs of the refractory element depletion, which is common in post–asymptotic giant branch (AGB) dusty binaries, or of a visual nebula. Absorption-line positions vary with an amplitude of ∼25 km s−1, suggesting the presence of a secondary component. Spectroscopic monitoring on a timescale from days to months is needed to search for regular variations. We conclude that IRAS 07080+0605 is most likely a binary system with an A-type component on its way toward the post-AGB evolutionary stage, as binarity is capable of explaining most of the observed features.
Diet of the exotic Madeiran wall lizard: first insights into trophic interactions in an Atlantic seabird sanctuary
Authors: Neves Verónica , Rund Dorothee , Pinho Catarina J. , Vasconcelos Raquel , Bustamante Paco , Quillfeldt Petra
Published: June 2022

The Madeiran wall lizard Teira dugesii is a relatively new species to the Azores Archipelago, where it was accidentally introduced about 150 to 200 years ago. This lacertid quickly became naturalised and now occurs in all the nine main islands of the Azores. At Praia Islet, off Graciosa Island, the Madeiran wall lizard was recently observed preying on chicks of the threatened Monteiro’s storm-petrel Hydrobates monteiroi. To characterise the lizards’ trophic niche, we conducted a study of the diet of the Madeiran wall lizard at Praia using stable isotope analysis and next-generation sequencing. Our results indicate that the Madeiran wall lizard has a varied diet, consisting of at least 23 invertebrate taxa, 17 plant species, and occasionally, birds (two species detected, including storm-petrels). Marine derived food items were present in few samples, and it is vital to monitor the trophic interactions at Praia Islet to ensure the conservation of this threatened storm-petrel.
Genetically modified animal models of hereditary diseases for testing of gene-directed therapy
Authors: Polikarpova Anna V. , Egorova Tatiana V. , Bardina Maryana V.
Published: June 2022

Disease-causing genes have been identified for many severe muscular and neurological genetic disorders. Advances in the gene therapy field offer promising solutions for drug development to treat these life-threatening conditions. Depend­ing on how the mutation affects the function of the gene product, different gene therapy approaches may be beneficial. Gene replacement therapy is appropriate for diseases caused by mutations that result in the deficiency of the functional protein. Gene suppression strategy is suggested for disorders caused by the toxic product of the mutant gene. Splicing modulators, genome editing, and base editing techniques can be applied to disorders with different types of underlying mutations. Testing potential drugs in animal models of human diseases is an indispensable step of development. Given the specific gene therapy approach, appropriate animal models can be generated using a variety of technologies ranging from transgenesis to precise genome editing. In this review, we discuss technologies used to generate small and large animal models of the most common muscular and neurological genetic disorders. We specifically focus on animal mod­els that were used to test gene therapies based on adeno-associated vectors and antisense nucleotides.
Two new syntopic species of wolf snakes (genus Lycodon H. Boie in Fitzinger, 1826) from an imperiled ecosystem in the Song Giang River Valley of southern Vietnam (Squamata: Colubridae)
Authors: Nguyen Anh The , Duong Tang Van , Wood Jr. Perry L. , Grismer L. Lee
Published: June 2022

An integrative taxonomic analysis of species in the colubrid genus Lycodon Fitzinger, 1826 recovered two new syntopic species of the L. rufozonatus complex from the imperiled Song Giang River valley in Khan Hoa Province, of Southern Vietnam. Although L. truongisp. nov. and L. anakradayasp. nov. are syntopic, they are not particularly closely related and can be differentiated from each other and all other species in the L. rufozonatus complex on the basis of meristics, morphometrics, color pattern, and uncorrected pairwise genetic distance based on the mitochondrial gene cytochrome b. The discovery of these two new range-restricted species and a previously described range-restricted gekkonid in the genus Cyrtodactylus Gray, 1828 from the same valley, underscores the necessity of continued field work in the Song Giang River valley so as to catalog the unrealized herpetological diversity in this area and establish research-based conservation programs.

Published: June 2022

L’objectif de la recherche, dans le cadre d’une comparaison interculturelle entre la Pologne et la France, était de préciser les liens entre les différentes représentations de l’identité nationale et supranationale et leurs rapports avec les attitudes à l’égard des immigrés. Les résultats mettent en évidence : 1) des oppositions entre d’une part les identités ethnique et culturelle et, d’autre part, les identités civique, européenne et universaliste ; 2) que les identités ethnique et européenne sont plus présentes en Pologne, les identités civique et universaliste plus présentes en France ; 3) que les modèles d’intégration jouent un rôle médiateur sur les liens entre représentations de l’identité et attitudes à l’égard des immigrés. En discussion, on évoque l’intérêt d’étudier les effets de ces différentes représentations de l’identité en distinguant plus précisément les modèles d’intégration et en abordant le point de vue des immigrés.
Guerre en Ukraine : Schumpeter au pays des Soviets ?
Authors: Goya Michel
Published: June 2022

Le 24 février 2022, la Russie a envahi l'Ukraine. Le plan initial imaginé par Moscou visait à conquérir rapidement Kiev, à la manière de la doctrine américaine « choc et effroi ». Les Russes avaient cependant sous-estimé la cohésion de la nation ukrainienne et l'efficacité des troupes de ce pays. Ne réussissant plus à progresser, l'armée russe a choisi de concentrer ses opérations sur le Donbass et la côte de la mer Noire, où elle fait face à une forte résistance.
La Chine et le concept de troisième pôle
Authors: Alexeeva Olga V. , Lasserre Frédéric
Published: June 2022

Pour légitimer son intérêt pour la gouvernance et les ressources de l'Arctique, la Chine promeut le concept de troisième pôle, constitué de l'Himalaya et du plateau tibétain. Ce concept fait l'objet de représentations cartographiques originales qui placent la Chine au centre du monde, entre l'Arctique et l'Antarctique. Ces représentations tranchent avec les cartes européocentrées qui prédominent dans les pays occidentaux. Elles font partie du soft power de Pékin.
« Un autre monde ethnique » : l’homme de Cro-Magnon, l’idée de progrès et les dialectiques de la modernité en préhistoire
Authors: Blanckaert Claude
Published: June 2022

Découvert en 1868 dans un site des Eyzies (Dordogne), l’homme de Cro-Magnon est aujourd’hui distingué comme le parangon de la « modernité » tant physique que culturelle de l’espèce Homo sapiens . Qualifié dès les années 1950 de « Néanthropien », par opposition aux types archaïques qui le précèdent, il remplit un rôle essentiellement humaniste en embrassant toutes les populations actuelles du globe dans une seule ancestralité positive. Néanmoins, les premières diagnoses des fossiles de Cro-Magnon, conservés au Muséum national d’histoire naturelle, témoignaient au contraire de l’« étrangeté » des hommes des cavernes. Pour bien des observateurs, ils illustraient l’altérité absolue d’une « race » sauvage et violente, sans analogue « moderne » qui aurait, selon Paul Broca, péri brutalement sans descendance. D’un siècle à l’autre, l’inversion des représentations s’avère radicale. Ce revirement nous permet de réfléchir à la construction des catégories mobilisées par les acteurs des années 1860-1880 pour évoquer l’antiquité de l’homme et son devenir dans l’axe présumé d’un « progrès » des formes anatomiques et de la « civilisation », concept dynamique qu’on leur croit communément associé.
L’introduction de la photographie dans les laboratoires du Muséum au XIX e siècle : un nouvel outil dans les pratiques scientifiques
Authors: Lafontaine Lisa
Published: June 2022

Les fonds photographiques du Muséum national d’histoire naturelle datant du xix e  siècle représentent un pan encore méconnu de l’histoire des collections de l’établissement, malgré la récente prise en charge patrimoniale d’une partie d’entre eux à la bibliothèque centrale du Muséum. Ces images invitent à retracer le récit de leur constitution, qui permet d’établir la précocité et la diversité des voies de développement de la photographie au sein du Muséum. Loin de témoigner seulement de l’histoire d’une collection isolée, ces photographies offrent de nouvelles perspectives à l’histoire des pratiques scientifiques dans des disciplines peu identifiées pour leur emploi de la photographie (mammalogie, physiologie végétale, minéralogie). Elles permettent d’investir des questions plus épistémologiques, notamment celle du rapport des naturalistes à l’objectivité et à la notion de vérité scientifique par l’image.
Manipulation Under Anesthesia Is Associated With an Increased Rate of Early Total Knee Arthroplasty Revision
Authors: DeFrance Michael J. , Cheesman Quincy T. , Hameed Daniel , DiCiurcio William T. , Harrer Michael F.
Published: June 2022

Manipulation under anesthesia (MUA) after total knee arthroplasty (TKA) frequently has been used as a first-line treatment to restore functional range of motion after unsuccessful physical therapy. Although there are studies reporting that MUA assisted in restoring range of motion, there is a paucity of literature on the influence of MUA on the risk of revision TKA. The goal of our study was to determine whether MUA was associated with an increase in the rate of revision TKA within 2 years of MUA. A total of 49,310 patients within a single institution who underwent primary TKA were identified from 1999 to 2019. Data were matched at a 1:3 ratio (TKA with and without MUA, respectively) based on age, sex, and body mass index. A matched comparison cohort was conducted, with the MUA cohort having 575 patients and the no MUA cohort having 1725 patients. A statistically significant increase in the rate of noninfectious etiology revision TKA was found in the MUA cohort (7.3%) compared with the no MUA cohort (4.9%;
P
=.034). The most common reason for revision TKA after MUA was persistent stiffness, including arthrofibrosis and ankylosis; however, aseptic loosening, ligamentous instability, and periprosthetic fracture were found to be responsible for 21.4% of revision TKA procedures. Although MUA is a commonly performed procedure for treating stiffness after primary TKA, the orthopedic surgeon should counsel patients on the association of increased rate of revision TKA after MUA, most commonly, persistent stiffness.

Periscapular Fibromatosis With Intrathoracic Invasion in a 3-Year-Old Boy
Authors: Zargarbashi Ramin , Mahmoudi Ehsan , Khalaj Kamand , Vosoughi Fardis , Mollaeian Mansour , Baghbani Salar
Published: June 2022

Fibromatosis is an extremely rare tumor that arises from the myofascial tissue and has high rates of infiltration and recurrence. Fibromatosis of the chest wall is even less common, and wide surgical resection is the preferred treatment alternative to radiation therapy, chemotherapy, and systemic treatments. We report the case of a 3-year-old boy with radiologically and pathologically confirmed fibromatosis of the periscapular region who underwent wide resection. We discuss diagnosis, treatment options, and technical pearls for a desmoid tumor of the chest wall. The resection should go through healthy tissue because of the infiltrative nature of the tumor. Although visceral involvement did not occur in this case, surgeons should be aware of its possibility, and surgery should be performed by a multidisciplinary team, including a pediatric orthopedic surgeon, a thoracic surgeon, and an anesthesiologist.

Published: June 2022

Development of the economy cannot be done at the cost of deterioration of ecology. Green finance is the most practical way of economic development and ecological development. To tackle the urgent challenges of climate change, several summits and conferences have adopted a sustainable development framework for their action plans. The 2030 Sustainable Development Goals (SDGs) are a unique collection of seventeen time-bound goals that strive to balance the three sustainability objectives of economic, social, and environmental sustainability. This research has been carried out to assess the present status of green finance in India and see its impact on startups. A green startup's success probability and importance are explained with specific case studies. By extracting the data from various published reports, it has been found that government initiatives are turning green by providing green finance, and Indian startups are exploiting this opportunity by the implementation of sustainable entrepreneurship. India has been on a path toward green project finance for some years now, and significant adjustments have been made to the country's financial sector to embrace ecologically friendly methods. Businesses are the economy's engine, and adopting sustainable business practices is critical for reaching carbon neutrality.
Single-step and multi-step methods for Caputo fractional-order differential equations with arbitrary kernels
Authors: Songsanga Danuruj , Ngiamsunthorn Parinya Sa
Published: June 2022

We develop four numerical schemes to solve fractional differential equations involving the Caputo fractional derivative with arbitrary kernels. Firstly, we derive the four numerical schemes, namely, explicit product integration rectangular rule (forward Euler method), implicit product integration rectangular rule (backward Euler method), implicit product integration trapezoidal rule and Adam-type predictor-corrector method. In addition, the error estimation and stability for all four presented schemes are analyzed. To demonstrate the accuracy and effectiveness of the proposed methods, numerical examples are considered for various linear and nonlinear fractional differential equations with different kernels. The results show that theses numerical schemes are feasible in application.
An application of data mining algorithms for predicting factors affecting Big Data Analysis adoption readiness in SMEs
Authors: Giang Nguyen Thi , Liaw Shu-Yi
Published: June 2022

The adoption of Big Data Analysis (BDA) has become popular among firms since it creates evidence for decision-making by managers. However, the adoption of BDA continues to be poor among small and medium enterprises (SMEs). Therefore, this study adopted the Technology-Organization-Environment (TOE) framework to identify the drivers of readiness to adopt BDA among SMEs. Chi-square automatic interaction detection (CHAID), Bayesian network, neural network, and C5.0 algorithms of data mining were utilized to analyze data collected from 240 Vietnamese managers of SMEs. The evaluation model identified the C5.0 algorithm as the best model, with accurate results for the prediction of factors influencing the readiness to adopt BDA among SMEs. The findings revealed management support, data quality, firm size, data security and cost to be the fundamental factors influencing BDA adoption readiness. Moreover, the results identified the service sector as having a higher level of readiness toward the adoption of BDA compared to the manufacturing sector. The findings are imperative for the enhancement of the decision-making process and advancement of comprehension of the determinants of BDA adoption among SMEs by researchers, managers, providers and policymakers.
Color of extra virgin olive oils enriched with carotenoids from microalgae: influence of ultraviolet exposure and heating
Authors: Murillo M.C. , García A.B. , Lafarga T. , Melgosa M. , Bermejo R.
Published: June 2022

A carotenoid-rich extract containing 2.5 mg/mL of lutein and 3.3 mg/mL of β-carotene from the microalga Scenedesmus almeriensis was added to ten extra virgin olive oils from four Spanish cultivars with differing degrees of ripeness, obtaining carotenoid enriched oils with lutein and β-carotene concentrations of 0.082 and 0.11 mg/mL, respectively. Extra virgin olive oils enriched with carotenoids from microalgae were studied by analyzing the effect on color of three different treatments: ultraviolet exposure, microwave heating and immersion bath heating. The methodology was designed to simulate, in controlled laboratory conditions, the effects of household treatments. Spectrophotometric color measurements were then performed to monitor color changes in the enriched and non-enriched extra virgin olive oil samples. Enriched oils are much more chromatic, darker and redder than natural oils. After 55 days UV irradiation, 40 min microwave heating, and 72 hours thermostatic heating, the average color differences for natural/enriched extra virgin olive oils were 98/117, 15/9 and 57/28 CIELAB units, respectively. In general, increasing temperature and ultraviolet exposure produced higher CIELAB color differences in the non-enriched samples. The addition of microalga extracts to extra virgin olive oils was found to induce some color stability and may constitute a future way of increasing the daily intake of beneficial bioactive compounds such as carotenoids.

Published: June 2022

The aim of this study was to investigate the removal of 3-monochloropropane-1,2-diol (3-MCPD) and glycidyl esters (GEs) from edible oils by using Metal Organic Frameworks (MOF) and natural clays. First, the model oil was treated with adsorbents and titanium (IV) butoxide-terephthalate MOF (Ti-MOF) and kaolin were selected as the best performing MOF along with natural clay, respectively, for the removal of 3-MCPD and GEs. The effects of treatment conditions were also investigated, 6.0% adsorbent level, 120 min treatment time and 95 ºC temperature were determined to be the best treatment parameters. Finally, palm oil samples were treated with Ti-MOF and kaolin under the selected conditions and removal of 3-MCPD and GEs was obtained at up to 27% and 58%, respectively. In conclusion, MOFs and natural clays showed good potential for the removal of 3-MCPD and GEs, and the efficiency of the treatment can be improved by modifying the adsorbents.
A Large-Scale MaxEnt Model for the Distribution of the Endangered Pygmy Madtom
Authors: Allen Samantha A. , Wells William G. , Mattingly Hayden T.
Published: June 2022

Aquatic resource managers often need detailed knowledge of the distributional patterns of imperiled species to facilitate conservation and recovery actions. The Pygmy Madtom Noturus stanauli is a rare catfish in family Ictaluridae that is federally listed as endangered under the U.S. Endangered Species Act. To better understand and forecast its distributional patterns, we assembled Pygmy Madtom occurrence records from past collections in the Clinch and Duck rivers in Tennessee, the only two waterways known to support populations of this species. We entered these presence-only coordinates into the maximum entropy species distribution model integrated with layers from geographic information systems. This approach produced suitability score maps and response curves for each environmental variable: flow rate, water velocity, stream order, gradient, air temperature, precipitation, canopy cover, and drainage area. The variables flow rate, drainage area, and canopy cover were important in predicting the distribution of the Pygmy Madtom throughout its range. The maximum entropy model predicted a high suitability score of Pygmy Madtom occurrence at new sites throughout the Upper Clinch River and the lower middle reaches of the Duck River. Our analytical approach gives managers a large-scale tool to better delineate the Pygmy Madtom's distributional range by identifying and prioritizing locations in the field for sampling at a later date to verify species presence and absence.

Published: June 2022

Les processus de transition et d’adaptation au monde universitaire, ainsi que l’orientation vers le monde professionnel constituent des défis majeurs pour les étudiants universitaires. Face à cette problématique, de nombreux dispositifs de soutien ont été proposés par les universités. Cependant, leur impact n’a pas souvent été évalué. L’objet de cette recherche vise précisément à présenter les résultats de l’évaluation d’un dispositif de soutien au projet d’études et au projet d’insertion socioprofessionnelle : le dispositif « Projet de formation ». Cette évaluation a été réalisée auprès de deux cohortes d’étudiants, à trois ans d’intervalle, selon trois niveaux d’analyses, inspirés du modèle d’évaluation de Kirkpatrick et Kirkpatrick. Les résultats de cette étude montrent une amélioration significative des bénéfices perçus du dispositif ainsi qu’une augmentation rapportée du transfert des compétences acquises. Après avoir situé les limites de notre étude, nous évoquons quelques perspectives au regard de l’approche évaluative employée.
Les croyances des étudiants sur la nature de leur intelligence : un facteur de participation dans des dispositifs d’aide à la réussite?
Authors: Massart Xavier , Mazy Aveline , Dejean Karine , Romainville Marc
Published: June 2022

Depuis plusieurs années, les universités proposent de nombreux dispositifs d’aide à destination des primo-étudiants pour favoriser leur réussite. Ces dispositifs ne parviennent pas toujours à atteindre les étudiants qui éprouvent le plus de difficultés dans leur apprentissage. C’est le cas du dispositif d’aide à la réussite dont il est question dans cet article qui vise à remédier au manque de maitrise des prérequis des primo-arrivants à l’université alors que Vieillevoye et al. (2012) ont mis en évidence une corrélation entre la maitrise de ceux-ci et la réussite en fin d’année. La maitrise des prérequis est ici évaluée à l’aide de tests (appelés « Passeports pour le bac »). L’objectif de cet article est de tenter de comprendre pourquoi certains étudiants ne participent pas aux séances de renforcement des prérequis testés alors qu’ils ont reçu un feedback les informant du manque de maitrise de prérequis. Notre hypothèse est que les travaux de Dweck (2010) concernant les liens entre « l’état d’esprit » (croyances des individus qu’ils ont à propos de leur intelligence) et leur attitude face à l’échec en termes d’engagement dans des activités de remédiation pourraient apporter des éléments de compréhension à ce faible taux de participation des étudiants. Dès lors, la présente étude vise à investiguer d’abord l’état d’esprit des étudiants à l’entame de leurs études universitaires pour analyser ensuite une éventuelle relation entre cet état d’esprit et l’importance qu’ils accordent aux prérequis et à la nécessité (ainsi qu’à la possibilité) de combler d’éventuelles lacunes. Les résultats présentés sont issus d’un questionnaire soumis à une large population : 1 585 primo-étudiants issus de l’Université de Namur et de l’Université Saint-Louis de Bruxelles. Ces résultats sont complémentairement analysés à la lumière de quelques entretiens qualitatifs menés par la suite.

Published: June 2022

Cet article rend compte d’une expérience d’évaluation d’un projet pédagogique porté à l’échelle d’une université dans le cadre d’un appel d’offre national français (IDEFI). Il s’agit de la présentation analytique de la démarche mise en place, des outils construits et des résultats obtenus à travers d’une approche de co-évaluation. La démarche d’évaluation du projet IDEFI, composé de plusieurs actions, comprend une phase exploratoire, une phase d’évaluation critique « négociée » et une phase de co-construction d’un outil d’évaluation adapté à chaque action. Avec la mise en place d’une co-évaluation, les expert-évaluateurs externes ont tenté de transformer les acteurs impliqués dans le projet en partenaires et de procéder à une confrontation des analyses externes et internes en vue de rechercher la signification la plus complète des résultats de l’évaluation. La lecture critique de cette expérience permet de discuter de l’intérêt du recours à la co-évaluation comme un acte formateur et formatif et un espace de dialogue critique entre acteurs impliqués dans les actions d’innovations pédagogiques, les décideurs institutionnels et experts-chercheurs externes. Le parti pris de cette expérimentation a été d’améliorer l’acceptabilité de l’évaluation et de contribuer au développement d’une culture d’évaluation au sein de l’institution.

Published: June 2022

The 2019 novel corona virus was declared a global pandemic by the World Health Organization (WHO) on March 11th, 2020. The world is stressed out because of this disease's high infectiousness and transmission mode. A predictive model of the COVID-19 outbreak is developed for India using state-of-the-art neural network models. The chapter evaluates the key features to predict the patterns, potential infection rate, and death of the present COVID-19 outbreak in India. In this chapter, machine learning methods such as artificial neural network (ANN) optimized by a bio-inspired optimization algorithm that is grey wolf optimization (GWO) and particle swarm optimization (PSO) have been implemented for the prediction of infection rate and mortality rate for the 5 days, 15 days, and 30 days ahead. The prediction of various parameters obtained by the proposed approach is effective within a certain specific range and would be a useful tool for administration and healthcare providers.

Published: June 2022

Background: Nurses are the backbone of the healthcare system. During the fulfilment of their duties and responsibilities, they experience various types of work-related risks, which harmfully affect their health and nursing quality.Objectives: This study aimed to explore and describe perceptions of nurses on occupational health hazards and safety practices in Ditsobotla public hospitals of North West province.Method: An exploratory, descriptive, qualitative research design was undertaken in this study. An explorative design allowed the researcher to identify key issues regarding nurses’ perceptions on occupational health hazards and safety practices using Donabedian structure, process and outcome. A total of 15 nurses of different categories participated in the study that formed four focus group discussions. Semi-structured focus group discussions of three to four participants were conducted until data saturation is obtained and at the point where no new themes from participants’ perceptions emerged. Creswell and Clark framework of data analysis was used to analyse data.Results: Three major categories emerged during data analysis: nurse’s perception on occupational health hazards in the health settings, Donabedian framework on assessing the quality of care in relation to occupational health hazards and occupational health and safety (OHS) practices. Eight themes were identified.Conclusion: Nurses’ perceived different occupational hazards that affect their normal duties and responsibility in the workplace. Future interventions such as training and education on OHS policy should be adopted to promote health and well-being of the staff.
Rediscovering the way of Islamic propagation by continuing the tradition of religion-based agriculture
Authors: Miharja Deni , Kusnawan Aep , Mustopa Salsabila
Published: June 2022

This study examines farming communities in Muslim villages that carry out one of the religious rituals in their agricultural cycle, namely tandur [planting rice seeds]. The study was then analysed with a theological analysis, namely Islamic theology, as the religion embraced by the community. The research method was carried out as follows: the researcher observed the research object in the Tanggulun Village of Subang Regency of West Java of Indonesia, where the case study was located. Researchers stayed at the research location and conducted interviews, supported by a voice recorder. The findings revealed that religious rituals performed by the farming community in the Muslim village, particularly during the agricultural cycle of planting rice seeds, gave rise to two types of tandur mantra. Such a religion-based culture does not conflict with the teachings of Islam as the religion of the farmers. The ritual represents local wisdom that the farming community can maintain and preserve theological and humanitarian elements inherited by Islamic da’wah [propagation] in the area. This study can show contemporary farmers the meaning of the mantra their parents used to chant. They can adapt whilst still honouring their religious heritage, even though the existing agricultural tools are relatively new.Contribution: This dissecting study of cultural narratives with theological studies can show that society still has traditions that can be maintained even in current conditions. Also, it opens the possibility of revealing local values in modern languages, so that there is a connection between past and present traditions. Disclosure of these values can be seen in the remaining culture, which is still practiced now, to enrich the study of ethnography, especially Sundanese ethnography. This is part of cultural science, which in this case is religious culture.

Ethical principles are among the topics that are widely emphasised in the Islamic society. Ethics is a set of values, do’s and don’ts that can play an important role in the effective management of organisations. If employees of organisations, especially medical staff, are working in the atmosphere of Islamic ethics, they show functional behaviours in line with the goals and missions of organisation. Due to the direct relationship and treatment of nurses with recipients of medical services, nurses’ behaviours have significant impact on the quality of services provided by medical centres. Therefore, the purpose of this study is to explore the relationship between Islamic ethics and commitment of 1100 Muslim nurses in Indonesia in 2021. This study was performed by descriptive-analytical correlational method. Data were collected using Islamic ethics and organisational commitment questionnaires and measured by Pearson correlation coefficient in Statistical Package for the Social Sciences (SPSS) and structural equation modelling analysis (SEM) in linear structural relationships (LISREL). The results indicate that Islamic ethics have significant and positive relationship with nurses’ commitment as p = 0.542 and t = 5.63.Contribution: According to the research findings, it can be concluded that commitment of nurses can be improved by applying Islamic ethics in medical centres.
An implicit good news in a Javanese indigenous religious poem
Authors: Chandra Robby I.
Published: June 2022

Contextualising biblical teaching entails the adoption of certain forms, terms or thought patterns that might confuse the original message, especially if the effort takes place in a Javanese culture context that is full of subtlety and indirect communication. This study analyses a Javanese poetry form that contains the narrative of Jesus’ encounter with a Samaritan woman. The indigenous poems are widely sung by the adherents of Javanese indigenous religions. However, only a few studies are conducted on such indigenous poems that contain Christian messages. This study examines whether or not the poetry form and religious terms that the writer used could serve as a vehicle to convey the good news message of the narrative of John 4:4–42 instead of creating impediment. Through literary form analysis followed by content analysis, the results showed that the Javanese poem contains several cantos, each with an embedded meaning. Finally, it intends to demonstrate how a combination, instead of contestation, of the indigenous, Islam and Christian terms is effective for the writer’s purpose. Thus, the writer’s choice was suitable in his effort to communicate the original teaching.Contribution: This study contributes to inter-religious communication by identifying the Javanese indigenous communication pattern, particularly the placement of their messages inside their poem’s structure and in various terminologies. Strengthening inter-religious communication to create a mutual understanding in Indonesian pluralistic society is needed especially as the Javanese indigenous religions are often misunderstood.
Theological education, spiritual formation and leadership development in Africa: What does God have to do with it?
Authors: Knoetze Johannes J.
Published: June 2022

Theological education, spiritual formation and leadership are all contested issues in the Church, especially within the African context. Although these topics are thoroughly discussed, the relation and the interdependence are not always clear. This article discusses these topics in relation to each other and in relation to the One who calls servant leaders to guide his church for her service in the world. The importance of the local church as missional church is emphasised in the article. Thus, what the faith community believes and teaches about God determines our ecclesiology, theological education and leadership. What does God have to do with theological education, spiritual formation and leadership development in Africa? The answer is everything! The article used a literary study to research the relationship between the different topics and the church and concluded that dependence exists between them.Contribution: Much is written on theological education in Africa. However, students come into theological education with an already established spirituality formed by other agents. The article contributes to the discussion about the relation between formal theological, spiritual formation and leadership. It emphasises the relation between the theological institution and the local church.

Authors: Modi Bhadrashil H. , Pretorius Deidré , Francis Joel M.
Published: June 2022

Background: South Africa is aiming to achieve herd immunity against the coronavirus disease 2019 (COVID-19) by the first quarter of 2022. The success of the COVID-19 vaccination roll-out depends primarily on the willingness of the population to take the vaccines.Aim: This study aimed to examine the willingness to take the COVID-19 vaccine, along with the factors of concern, efficacy and preferences of the individual, which may increase the willingness to be vaccinated.Setting: This study was conducted at the University of the Witwatersrand, Johannesburg, amongst adult students and academic and professional staff.Methods: A cross-sectional online survey from 27 July 2021 to 14 August 2021 was conducted. We performed descriptive and inferential analysis to determine the factors associated with willingness to take the COVID-19 vaccine.Results: A total of 2364 participants responded to a survey link and 82.0% were students, 66.8% were in the 18–29 years age band and females represented 64.0%. A total of 1965 participants (83.3%) were willing to receive a COVID-19 vaccine, the most preferred vaccines were Pfizer (41%) and JJ (23%), local pharmacy (29%) and General Practitioner (GP) (17%) were the preferred places for vaccination and the trusted sources of information on COVID-19 vaccines were the general practitioners (40.6%) and specialists (19.2%). Perceptions that vaccines are safe (adjusted odds ratio [aOR] = 31.56, 95% confidence interval [CI]: 16.02–62.12 for affirmative agreement) and effective (aOR = 5.92, 95% CI: 2.87–12.19 for affirmative agreement) were the main determinants of willingness to taking a COVID-19 vaccine.Conclusion: It is imperative to reinforce the message of COVID-19 vaccine safety and efficacy and to include the GPs and the community pharmacies in the vaccination roll-out in South Africa.
A framework for closed-loop supply chain adoption by small, medium and micro enterprise fashion retailers in South Africa
Authors: Muhwati Chenai , Salisbury Roger H.
Published: June 2022

Background: The implementation of closed-loop supply chain strategies is increasing as the focus grows on the sustainability challenges of the fashion industry. However, their implementation is more widely adopted and researched from the perspectives of larger retailers in developed economies outside of Africa, limiting the widespread applicability of their findings to stakeholders in developing countries such as South Africa.Aim: The study explored and proposed a decision support framework for the potential coordination of closed-loop supply chain strategies by small, medium and micro enterprise (SMME) fashion retailers in South Africa.Setting: This research study was conducted in South Africa with stakeholders in the Western Cape, KwaZulu-Natal, Gauteng and Limpopo provinces.Methods: This descriptive, qualitative research approach used purposive sampling, in the form of judgment sampling, to select 14 participants. The interviews were then transcribed and transferred to Nvivo™ software to identify and analyse themes within the data.Results: The findings revealed that while some SMMEs would consider or were already considering adopting closed-loop strategies, various challenges and limitations existed related to the sizes of their businesses, their restricted relationships with supply chain stakeholders and their operation in an African developing country. A decision support framework was established, which considers this context and could aid in the implementation of circular strategies by such retailers.Conclusion: Despite resource limitations, opportunities exist for SMME retailers to adopt closed-loop supply chains and become globally competitive, following international focus on accountability and sustainable consumption. The decision support framework is suitable for such stakeholders to facilitate collaborative efforts towards achieving end-to-end sustainability.
Cutaneous squamous cell carcinoma in vertically acquired HIV and epidermodysplasia verruciformis
Authors: Mandikiyana Chirimuta Linda A. , Ndowa Francis J. , Pascoe Margaret J.
Published: June 2022

Introduction: Acquired epidermodysplasia verruciformis (EV) is a skin disorder that has been described in individuals with perinatally acquired HIV. Many cases have been identified in sub-Saharan Africa in keeping with the epidemiology of HIV infection compared to the rest of the world, where cases are rare. Epidermodysplasia verruciformis skin lesions may undergo malignant transformation. There are few documented cases of malignant transformation of these skin lesions. We describe a patient with an EV-like skin rash who developed cutaneous squamous cell carcinoma (SCC).Patient presentation: A 25-year-old man, on antiretroviral treatment for 12 years, presented with a generalised skin rash since the age of 11 years, and a 7-month history of a persistent scalp ulcer. He had no history of trauma, radiation or other chronic conditions. Despite an undetectable HIV viral load, he had failed to immune reconstitute (CD4 42 cells/µL). Physical examination revealed a generalised hypopigmented, papular skin rash resembling verruca plana and a 3 cm × 3 cm ulcer with rolled edges on the right parietal region of the scalp. There were no palpable lymph nodes in the head and neck areas. Biopsy of the ulcer revealed moderately differentiated SCC.Management and outcome: Wide local excision of the lesion was done under local anaesthesia and histological analysis confirmed completely excised moderately differentiated SCC. Further examination four weeks later revealed two, smaller, histologically similar scalp lesions which were completely excised.Conclusion: Patients with acquired EV require thorough, frequent examination for skin lesions with possible malignant transformation. Early identification of malignant transformation and treatment with surgical intervention is curative.
Blood donor app usage behaviour and perceptions: Considerations for a blood donation app
Authors: Potgieter Andrea , Rensleigh Chris
Published: June 2022

Background: South Africa often experiences critically low blood stock levels, making it vulnerable to blood shortages for everyday use and during times of crisis. There are over 3.5 billion smartphone users worldwide and, during 2019, app downloads were estimated at 204 billion. Considering that at least 51% of South Africans own a smartphone that can access the Internet and apps, it is clear that blood donation organisations in South Africa could benefit from engaging with the public through a mobile app.Objectives: This article aimed to determine whether South African blood donors’ app usage behaviour and perceptions were conducive to introduce a blood donation app, and what these behaviours and perceptions could reveal, to support South African Blood Donation Organisations in their recruitment and engagement endeavours.Method: The research problem discussed in this article sought to highlight the app usage behaviour of blood donors, and their perceptions about a proposed blood donation app. Forming part of a larger sequential mixed-methods study, the data presented in this article were gathered through a quantitative online questionnaire involving2154 South Africans respondents.Results: The findings revealed that the majority of respondents owned a smart device and that they used apps falling within the ‘Communication’ category. Of the respondents, 41% believed that a blood donation app will encourage younger South Africans to donate blood more regularly, whilst 25% of respondents were of the opinion that an app will motivate all South Africans to donate blood more often.Conclusion: The value of this research lies in the insight gained into the behaviour and perceptions of South African blood donors, which can inform the conceptualisation and design of a blood donation app, thereby improving its efficacy and subsequently supporting the strategy of employing such a technology to increase blood donation.
