Leveraging ecocomDP as a Flexible Intermediate Data Pattern to Expose NEON Biodiversity Data in GBIF
Authors: Sokol Eric , Smith Colin , O'Brien Margaret
Published: August 2022

The Environmental Data Initiative (EDI) and the National Ecological Observatory Network (NEON) have been developing a flexible intermediate data design pattern for ecological community data called “ecocomDP”, which is intended to promote FAIR data principles. Specifically, this effort will enhance the discoverability of and access to biodiversity data from NEON and EDI data holdings, including data from the United States Long Term Ecological Research (USLTER) program (O'Brien et al. 2021). The ecocomDP data model is applied in the ecocomDP R (programming language) library, which provides tools for independent researchers to format their data following the ecocomDP standard, as well as tools to search and visualize data from NEON and EDI data holdings in their R environment. The flexibility of the ecocomDP data model allows for much of the ancillary data associated with observation events to be preserved. Here we describe a modular workflow that is under development to expose ecocomDP-formatted data packages in the Global Biodiversity Information Facility (GBIF) data portal (Fig. 1). Specifically, we highlight an effort to apply this workflow to create a pipeline to convert and submit NEON biodiversity data products to GBIF.

EDI now has more than 70 data packages reformatted to the ecocomDP model, and has nearly finished developing a conversion of that intermediate format to a Darwin Core Archive (DwC-A, event core) format (Wieczorek et al. 2012) for submission to GBIF. This workflow takes advantage of EDI’s dataset subscription service, which triggers creation of an updated DwC-A when an original dataset is revised. Because ecocomDP provides a standardized input to this submission process, any data package in the ecocomDP format can be exposed in GBIF through this workflow. Thus, we are working to leverage the EDI-managed conversion and submission process to expose NEON data in GBIF, which is possible because of the existing mappings of NEON data products to ecocomDP (Li et al. 2022). This will include data products representing terrestrial and aquatic organisms (Table 1) from all NEON sites, spanning the entire United States.

The overall goal of this effort is to provide an automated, modular workflow with complete provenance to submit NEON and EDI datasets to GBIF, built in such a way that datasets can be properly updated as new samples are collected and the data are published. The development of such a submission pipeline will provide a standardized process to expose biodiversity data from two continental scale networks, NEON and the U.S. National Science Foundation's Long-term Ecological Research network in GBIF. Further, the modularity of the workflow will allow independent researchers to adapt tools developed in this effort for their data archiving and publishing needs.

Apprendre de la crise sanitaire : Existe-t-il des conditions favorables au bien-être des télétravailleurs à domicile ?
Authors: Nande Florence , Weber Marie-Laure , Bouchet Stéphanie , Loup Pierre
Published: August 2022

La crise sanitaire liée à la Covid-19 a bouleversé de nombreuses certitudes et a conduit à de considérables changements au sein du monde du travail. La pratique du télétravail, qui était jusqu’alors peu répandue s’est fortement généralisée, le gouvernement ayant incité voire contraint les organisations à adopter ce mode d’organisation. À partir des résultats d’une enquête par questionnaire réalisée au cours de la première période de confinement, cette étude cherche à tirer des enseignements de cette période en s’interrogeant sur les conditions favorables au bien-être au travail pour les télétravailleurs à domicile. Plus précisément, en nous appuyant sur la Méthode de l’Analyse Comparée (QCA), l’objectif est ici de mettre en évidence les conditions combinées favorables qui génèrent du bien-être pour le salarié en télétravail à domicile. Quatre configurations de conditions sont ainsi repérées et permettent d’apporter à la littérature des clés de compréhension.
L’« observatoire volant » de Camille Flammarion : enjeux médiatiques d’une science récréative
Authors: Courant Elsa
Published: August 2022

En 1867, l’astronome Camille Flammarion découvre l’aérostation qui devient pour lui une véritable passion. Les récits de ses ascensions font l’objet de publications multiples dans la presse et sous forme d’ouvrages, au milieu d’une ferveur populaire pour les vols en ballons. Décrivant les impressions produites par ce nouveau mode de déplacement, Flammarion montre comment la navigation aérienne bouleverse les frontières entre les pratiques savantes et sociales, à mi-chemin de la science, de l’événement médiatique et du sport à sensation. Ses trajets, de la capitale vers les campagnes et de France en Prusse, contribuent à dessiner une partition des territoires singulière. Or la couverture médiatique des voyages, y compris dans ses zones d’ombres, porte la trace d’enjeux intellectuels, politiques et sociaux majeurs dont rendront compte les multiples rééditions de ses ouvrages.
Aventures sélénites dans trois récits pour la jeunesse (1830-1860)
Authors: Sylvos Françoise
Published: August 2022

Trois voyages dans la lune destinés à la jeunesse, Les Aventures de Robert-Robert (1839) de Louis Desnoyers, Les Petits Neveux de Gulliver d’Émile Bouchery (1842), Les Aventures d’un aéronaute parisien dans les mondes inconnus d’Alfred Driou (1856) sont abordés sous l’angle de l’histoire culturelle, des genres et de l’imaginaire. La projection du récit dans l’espace libère la créativité et l’imaginaire qui se conjuguent avec le positivisme de la leçon de choses. Dans la quatrième dimension de la fantaisie située entre effroi, rêve et rire, s’élabore dès le romantisme la poétique de la science-fiction et s’amalgame l’approche objective du cosmos avec une créativité délirante et réjouissante. L’espace, miroir de la terre, est aussi surnature et condense des éléments empruntés au réel dont sont issus les prototypes de l’extra-terrestre et du super-héros.
Filles de l’air, filles de rien. Le fabuleux roman oublié des femmes aéronautes au XIX e siècle
Authors: Robène Luc
Published: August 2022

L’histoire n’a jusqu’ici que faiblement documenté les aventures de jeunes femmes dont l’activité aérostatique participe à redéfinir les horizons de la conquête de l’air au xix e  siècle. Faire surgir de l’ombre ces figures oubliées oblige à recueillir et assembler des fragments de récits, témoignages, lettres, et à capter les reflets fugaces produits tantôt par le fait divers, la fiction, la poésie ou par la prose des publicistes. Ces lignes se croisent, se répondent parfois, et rendent visible, au travers de lentilles singulières, l’activité de celles qui, aéronautes d’un jour, professionnelles de l’air, amatrices, n’ont dans leur grande majorité guère pu documenter leur propre activité. L’ensemble permet d’autopsier la problématique d’une féminité conquérante aux prises avec les controverses et les troubles qu’elle a pu susciter en son temps.
L’intérêt : les tribulations d’une catégorie esthétique au seuil du XIX e siècle
Authors: Parmentier Marie
Published: August 2022

L’article cherche à cerner les contours de l’intérêt, qui constitue, au seuil du xix e  siècle, une catégorie héritée de deux siècles de poétique théâtrale et romanesque, et qui se situe au confluent de la poétique et de la réception : l’intérêt du lecteur ou du spectateur pour les personnages, c’est-à-dire son vif attachement pour eux, détermine l’intérêt de l’action, c’est-à-dire la tension qu’elle crée. L’intérêt est alors un critère de valeur esthétique de l’œuvre. Cette valeur en vient toutefois à s’inverser au xix e  siècle : l’intérêt est dès lors associé à une littérature médiocre, agitant sans vergogne les excès du pathos . Pour les romanciers, qui ne peuvent envisager sans dommage de renoncer à l’intérêt des lecteurs, se met en place une sorte d’aporie : il va falloir négocier avec l’intérêt ou bien le renouveler.

Authors: Wang Jing , Cui Dong , Zuo Xiao Bao
Published: August 2022

Concrete carbonation serves as one common durability issues in reinforced concrete structures at present. In order to understand the carbonation mechanism, many methods were developed by previous researchers for the characterization of concrete carbonation. For example, Phenolphthalein spraying method, Thermo-gravimetric analysis (TGA), X-ray diffraction, Fourier Transform Infrared Spectroscopy (FTIR), Mercury intrusion porosimetry (MIP), etc.. In this paper, all existed carbonation methods were summarized, and, based on the parameter (pH value inside pores, microstructure, chemical composition, etc. ) each method focuses, the function behind method was elaborated. Finally, this paper discussed the pros and cons of current methods, and further developing directions were proposed.
Effect of Sericin Additive on Cellulose Acetate Membrane Morphology and Protein Rejection
Authors: Waheed Hizba , Mukhtar Amir
Published: August 2022

Cellulose acetate (CA) membranes are synthesized for filtration purpose. The hydrophilic sericin macromolecule is blended with CA to analyze the enhancement of protein rejection. Increase in hydrophilicity, water permeation and protein rejection was studied by using contact angle, pure water flux (PWF) and Bovine serum albumin (BSA) permeation respectively. Surface modification was examined using SEM and AFM. The results show the homogenous blending of sericin in CA matrix and effective fabrication of membranes. In order to gauge the efficiency of casted membranes in protein filtration and separation, water flux and protein rejection were studied. The concentration of sericine protein was altered in CA polymeric solution that imparts variable properties to fabricated membrane samples. Increment in wt% of sericine up to 7.5 in polymer dope solution, enhances BSA rejection to the limit of 96%. The amino linkages between sericine and the BSA of feed resulted in the holding of protein by sericine, which leads to low permeation of BSA via CA-Sericine membrane M4.

A meso-geometric model of pore network was established to predict the sound absorption performance of porous asphalt mixture.Based on characteristics of the pore structure of porous asphalt mixture, the meso-structure model of porous asphalt mixture was established by using physical geometry principle.For the meso-void structure, the electro-acoustical equivalent circuit was established based on electro--acoustic theory, and the relationship between the sound absorption coefficient and the total impedance was established.The model was verified by image processing technology and standing wave ratio method.DIP image processing technology was used to determine these void structure parameters of porous asphalt mixture specimens, and standing wave tube method was used to test the sound absorption coefficient of specimens.The data predicted by the model was compared with the measured data.The results show that the model of meso-void structure and the model of sound absorption coefficient of porous asphalt mixture based on electro--acoustic theory are feasible and effective.
Effect of Bracket Width on Bending Deformation of NiTi Arch Wire: A Finite Element Study
Authors: Ishak Latiffi Nur Ainul Nurina , Razali Muhammad Fauzinizam , Mahmud Abdus Samad
Published: August 2022

The force transferred from the NiTi arch wire to the tooth during orthodontic treatment is strongly dependent on the geometry of the wire and brackets used by the orthodontist. This study investigated the effect of orthodontic bracket geometry on the bending behaviour of superelastic NiTi arch wire. A three-dimensional finite element models of wire bending in three-brackets configuration was developed by employing superelastic user material subroutine and contact interaction. The finite element model was used to anticipate the bending forces and stresses of NiTi wires as they were engaged in various slot width dental brackets. Four different bracket widths were considered, ranging from 1.5 mm to 4.5 mm. Throughout the bending course, the superelastic NiTi wire bent in the 4.5 mm width bracket continuously demonstrated the highest bending force in comparison to the other bracket widths. As the bracket width was raised from 1.5 mm to 4.5 mm, the wire unloading force measured at 2.5 mm deflection increased gradually from 0.40 N to 1.7 N. The bending stress of the wire deformed in the 1.5 mm width bracket was 543 MPa, band it increased to 1051 MPa when the 4.5 mm width bracket was used. The proportion of complete martensite structure at the wire curvature gradually increased as the width of the bracket slot was increased.
The Durability of Ultra High Strength Fibre Reinforced Cementitious Material
Authors: Paglia Christian , Antonetti S.
Published: August 2022

The technology of concrete greatly evolved in the recent years. The use of cements with a high dosage and the addition of fibres allowed a very compacted cementitious matrix. This fact may greatly affect the durability of a cementitious system. In this work, the durability of an ultra high strength fibre reinforced concrete was studied. The microstructure was dense, compact and exhibited a low capillary and total porosity as well as water permeability. Fluid resin penetration tests under pressure also showed a local difference in the penetration depth: from a thin surface layer to local small regions. Thus, the penetration potential of salts and water transporting degrading substances from the surface was reduced. The cement-based material was exposed to accelerated freeze/thaw and sulphate penetration tests, to clarify the durability and the capability of the low porous matrix to withstand the ingress of substances. In both cases the resistance was significantly higher as compared to conventional concrete. The crystalline quartz-rich matrix and the chemistry also played a relevant role in the low degradation of the system.
Apriori sample size estimation and reporting in original articles published from 2012 to 2020 in two Asian orthodontic journals
Authors: Ramteke Shivangi , Kumar Sekar Santhosh , Madhan Balasubramanian
Published: August 2022

AIMS:

To evaluate the proportion and completeness of reporting apriori sample size estimation (SSE) in research articles published in the Journal of Orthodontic Science (JOS) and the Journal of Indian Orthodontic Society (JIOS).

MATERIALS AND METHODS:

All online research articles published in both journals from 2012 to 2020 were screened. Those reporting apriori SSE were analyzed for the study design and completeness of SSE reporting (outcome parameter and assumptions, Type I error, Power/type II error, one or two-tailed test, the method used, justifications for assumptions, adjustments in sample size, and the target sample size). Chi-square or Fisher exact test was used to analyze the differences between the journals in the proportions of articles reporting these characteristics.

RESULTS:

Twenty articles (13.2%) in JOS and 24 (8.3%) in JIOS, have reported apriori SSE [χ2 (1, N = 440) = 2.573, P=0.10]. Non-clinical and quasi-experimental studies formed nearly two-thirds of articles reporting SSE in JOS. Quasi-experimental (34%), randomized controlled trials (28%), and cross-sectional studies (24%) formed the bulk of articles reporting SSE in JIOS. Type II error/power was the most frequently reported characteristic in both (75% and 95.8% in JOS and JIOS, respectively), and the number of tails was the least (5% and 0%, respectively). More articles in JOS than JIOS reported the outcome variable used [65% vs. 12.5%, χ2 (1, N = 44) = 12.99, P <.001] and provided justifications for the assumptions [70% vs 33.3%, χ2 (1, N = 44) = 5.86, P = 0.01].

CONCLUSION:

The extent and completeness of reporting apriori SSE are suboptimal in these journals and require prompt and stringent curative measures.
Cross-cultural adaptation and validation of the malocclusion impact questionnaire for patients seeking orthodontic treatment
Authors: Agou Shoroog , Al-Sakkaf Ghadir , Barboud Lujain , Elhussein Mustafa
Published: August 2022

OBJECTIVES:

To assess the adaptability and validity of the Arabic version of the Malocclusion Impact Questionnaire (MIQ-AR) in patients seeking orthodontic treatment.

MATERIALS AND METHODS:

This cross-sectional survey was conducted on a convenience sample of 77 Arabic speaking, healthy, 10–16-year-old children, selected based on their personal perception of “needing braces.”. The participants completed the MIQ-AR and the Child Perceptions Questionnaire for children aged 11–14 (CPQ11-14), answered two global questions, and had their Index of Orthodontic Treatment Need, Dental Health Component (IOTN.DHC) scores recorded. Construct validity was examined by measuring the correlation between the MIQ-AR score and the responses to the two global questions. Criterion validity was examined by measuring the correlation between the MIQ-AR and both the IOTN.DHC and CPQ11-14 scores.

RESULTS:

Moderate positive correlations were observed between the MIQ-AR scores and the first (ρ = 0.320, P < 0.001) and second global questions (ρ = 0.388, P < 0.001). A strong positive correlation was found between the total CPQ11-14 and MIQ-AR scores (ρ = 0.597, P < 0.001). A positive gradient was observed between the MIQ-AR scores and IOTN.DHC scores.

CONCLUSION:

Our results indicate that the MIQ-AR is a valid tool for measuring oral health-related quality of life in patients with malocclusion, with good psychometric parameters. These preliminary findings require further testing in various settings involving a larger and more diverse sample.
Ability of piezocision to retain orthodontically moved teeth in a goat model
Authors: Tokhtah Hana A. , Alhadlaq Adel M.
Published: August 2022

OBJECTIVES:

to evaluate the effectiveness of piezocision in enhancing retention when performed after orthodontic tooth movement.

METHODS:

Four mature goats had their second incisors removed bilaterally. For each goat, the two sides of the mandible were either treated with piezocision or served as a positive control. Using fixed orthodontic appliance, the first and third incisors on each side were approximated and then retained in place for two weeks. Relapse was measured by the amount of space developed between the approximated incisors after six weeks from the end of the retention period. The periodontal ligament of all incisors was assessed histologically with micro computed tomography and regular hematoxylin and eosin staining.

RESULTS:

A significantly less relapse was observed in the piezocision group than in the control group (p ≤ 0.05). Bone formation occurs in the vicinity and periphery of the periodontal ligament and thus results in the narrowing of the periodontal ligament.

CONCLUSION:

A protocol of post-orthodontic retention involving piezocision can be promising to enhance stability of orthodontic treatment outcome.
Determination of proper band size for stainless steel crowns of primary second molars
Authors: Moradinia Mohammad , Sarlak Hamid , Mohammad-Rabei Elham , Almasi-Hashiani Amir , Shamsi Alireza
Published: August 2022

BACKGROUND AND OBJECTIVES:

Fixed space maintainers are often used following primary tooth loss. In this process, selection of a proper band size for stainless steel crowns (SSCs) is often performed by trial and error, which increases the chairside time and risk of contamination of the tried bands with saliva, blood, and gingival crevicular fluid, necessitating their subsequent sterilization. This study is aimed at determining the proper size of prefabricated bands for all SSCs of primary second molars.

MATERIALS AND METHODS:

In this cross-sectional study, seven examiners, including three orthodontists and four pediatric dentists attempted to select the proper band size for 24 primary second molar SSCs (3M). They selected the proper band size for each size of SSC six times in three sessions. The significance of all selected choices was carried out using the test of proportions.

RESULTS:

The most commonly selected bands for EU2, EU3, EU4, EU5, EU6, and EU7 SSCs were sizes 31+, 32+, 34, 35+, 37, and 38, respectively, and the proper bands for EL2, EL3, EL4, EL5, EL6, and EL7 SSCs were sizes 30, 31+, 32+, 33+, 35 and 36+, respectively. The difference in the frequency ratio of different choices for all sizes of SSCs was significant (P < 0.05).

CONCLUSION:

The current study determined the proper band size for all SSCs of primary maxillary and mandibular second molars. This information can help dental clinicians in selecting the proper band size for SSCs without trial and error.
A Rare Case of Mantle Cell Lymphoma of Nasopharynx and Larynx with Synchronous Presentation Treated with Volumetric Modulated Arc Technique Radiotherapy
Authors: Sarkar Sujata , Bashir Irfan , Yotham Roopesh Reddy , Sharma Ritesh
Published: August 2022

Mantle cell lymphoma (MCL) or mature peripheral B-cell lymphoid neoplasm is a type of non-Hodgkin's lymphoma. It is more common in elderly males. It is very rare, accounting for less than 1% of head and neck malignancies. MCL is usually positive for CD20, CD5, CD43, cyclin D1 and negative for CD10, CD23, and BCL6. It is a very aggressive neoplasm, and hence, patients often present in advanced stage. Due to its rare incidence and short clinical course, there are limited data on standard treatment protocols. Even with the present treatment protocols, only 30% of patients achieve complete response. Here, we present a case of synchronous presentation of MCL of the nasopharynx and larynx in a 69-year-old male. We aim to discuss the investigations and treatment done with volumetric modulated arc technique radiotherapy that led to complete response.

Published: August 2022

Background:

The SARS-CoV-2 pandemic has also had a profound impact on cancer treatment delivery and organization. Oncology clinics have developed a number of procedures and used formulas related to radiotherapy doses to continue their activities. Aims and Objectives: We explored the impact of SARS-CoV-2 pandemy on the personnel and cancer patients undergoing radiotherapy in a radiotherapy department during the first year.

Materials and Methods:

845 patients were treated over the course of a year, 195 of whom consented to participate in the study. The Elekta Mozoiq system and radiotherapy cards were evaluated, and the time intervals between the treatments during the radiotherapy were recorded. Biologically Effective Dose losses were calculated in the radiotherapy dose due to the interruption to treatment, and necessary calculations were made for the delivery of the initially planned dose.

Results:

The mean age of the patients was 59 years (range 19-78). There were 110 male (56.4%) and 85 female (43.5%) participants. The treatment of 4.6% (9 patients) of the patients was discontinued because of SARS-CoV-2 infection during radiotherapy. The greatest added fraction for a patient with prostate cancer was three while the lowest was one for a patient with lung cancer, based on the TDF calculation. During this period, 16% of the staff was infected with COVID-19.

Conclusion:

This study demonstrates the effect of the COVID-19 pandemy on patients and personnel in a radiotherapy clinic, and its management during one year.
An Unusual Orbital Presentation of Covid-19-Associated Mucormycosis
Authors: Swain Santosh Kumar
Published: August 2022

Coronavirus disease 2019 (COVID-19) is an ongoing pandemic that spreads mainly through close contact and tiny respiratory droplets. The ocular surface is a potential site for transmission, whereas the ophthalmologists are highly potential to acquire infection. Because of the presence of the angiotensin enzyme 2 in different ocular tissues and cytokine storm results in vasoconstriction, ischemia, hypercoagulopathy, and thromboembolic phenomenon, this virus easily binds and in different ocular manifestations such as conjunctivitis, retinal vascular occlusion, diabetes retinopathy, ocular nerve palsies, and orbital mucormycosis. Mucormycosis is a life-threatening infection that often affects patients with diabetes mellitus and other immunocompromised patients. The diagnosis of mucormycosis is usually done by microbiological tests and radiological investigations. Proper ocular care and awareness among clinicians need the hour for prompt management of orbital mucormycosis. Here, we are presenting a case of COVID-19-associated mucormycosis with subconjunctival involvement of mucormycosis.

This paper intended to assess the influence of indiscipline on teacher attrition in public secondary schools in Kilimanjaro and Manyara regions. Specifically, the paper aimed at examining the indiscipline cases that cause teachers’ attrition; examine the frequency of cases on indiscipline issues; and the measures taken to address indiscipline cases. The paper was guided by motivation theory based on conduct for efficient management and administration of punishment to violators. The study employed cross section research design with mixed approaches. The sample size of the study was 140 respondents. Simple random and snow ball sampling was used to select in-service and teachers who left teaching respectively. Quantitative  data were analysed using descriptive and binary logistic regression. The findings revealed that examination malpractices, student sex  harassment and truancy influenced teacher attrition. Among the measures taken were: transfer, summary dismissal and reduction in salary that led  to teachers quitting teaching. As for frequency of indiscipline cases among teachers, the study revealed the mean score of indiscipline as above 50  per cent which revealed that the variable influences teacher attrition. The study concludes that indiscipline cases influences teacher attrition. The  study recommends to the President’s Office Regional Administration and Local Government to improve teachers discipline by equipping Teacher  Service Commission staff with all necessary inputs to supervise accordingly. School management should remind their staff on professional code of  ethics, and the Government should execute the law number 3 of 1972 for teachers who engaged in indiscipline cases by imposing severe  punishment to offenders.
Entry and sustenance strategies of dairy processing firms into supermarkets in Nairobi City County, Kenya
Authors: Mugo Kamau Vincent
Published: August 2022

The growth of dairy processing firms is highly dependent on doing business with supermarkets as supermarkets are powerful actors in the dairy product value chain. This paper therefore, examines the entry and sustenance strategies used by dairy processing firms into supermarkets in Nairobi, Kenya. By way of methodology, this is a case study that conducted two rounds of sampling on a population of eleven dairy processing firms. The first round was a census to verify existence and sizes of predetermined dairy processing firms. In the second round, stratified random sampling technique was conducted to create three categories and thereafter, select dairy processing firms for inclusion in the sampling frame. Data was analyzed through thematic analysis. Findings indicate that New Product Development, distribution chains, diversification, packaging, Mergers and Acquisitions, food safety strategies, market and marketing, and products serve as important entry strategies into the supermarket chains. Organizational structure and slotting allowance were crucial sustenance strategies. Dairy processing firms experience challenges such as safety and health standards, dairy product imports, export markets, trade credit, product promotion, legal certification, supermarket private standards, supermarket own labels and market challenges. Small, medium and large dairy processing firms apply different entry and sustenance strategies and experience different challenges while doing business with supermarkets. This paper, to the best of my knowledge, is the first to explore the different entry and sustenance strategies utilised by small, medium and large dairy processing firms for purposes of gaining access and sustaining their products into supermarkets in Nairobi, Kenya.

The study investigated the role of top management support in the implementation of public sector supply chain management practices with specific reference to public procuring entities in Harare, Zimbabwe. In order to achieve the intended research objectives, the study used a quantitative research design where 217 questionnaires were distributed to both employees and management. The study found that top management from the public procuring entities did not provide adequate necessary information and communicationtechnological tools necessary for effective supply chain management planning. It was also revealed that the top management in the public procuring entities does not provide an organizational vision that embraces supply chain management continual improvement. Furtherance, the study concluded that there is no commitment supported by adequate resources on the implementation of supply chain management practices and strategies from the top management in the public sector procuring entities. The study recommends that it should be the role of management to implement realistic objectives and provide supply chain management related training to their employees, enhance teamwork effort and provide priority and attention to internal and external customers. The support of senior management support would greatly influence the successful implementation of supply chain management practices in public procuring entities.
Towards a Sustainable Corporate Social Responsibility Discharge and Accountability in the Extractives Industry
Authors: Asare Emmanuel Tetteh , Addo Salomey O. , Aveh Felix Kwame
Published: August 2022

The paper examines how Corporate Social Responsibility (CSR) activities manifest and their respective discharge and accountabilities in the extractives industry. The study employs content analysis to examine the sustainability reports of two leading extractive firms in Ghana namely, AngloGold Ashanti and Tullow plc. Thereafter, it engages relevant stakeholders in interviews to probe deeper into the results of the content analysis to corroborate the evidence from the companies. The results indicate that the CSR discharge and accountability of the firms are inconsistent with society’s expectations and that the firms employ legitimation mechanisms in their CSR practices to obtain and retain social licenses to operate. Hence, CSR discharge and accountability of the firms are rather superficial and rhetoric in nature and performed just to keep themselves in a positive light, while enhancing corporate reputation and visibility. The study contributes to the CSR literature by specifically focusing on how CSR activities manifest and their respective accountability discharge in the extractives industry. The paper takes a holistic multidimensional methodological approach to resolve CSR and respective accountability issues, unlike existing studies that look at the substantive issue on a piecemeal basis, thus, either through interviews or content analysis. It provides useful information to policymakers and a reference point to industry on their CSR accountability strategies and subsequent implementation.

A comparison of the sensory processing skills of children (6-10 years old) with autism and those that are typically developing as assessed by a short sensory profile in Harare, Zimbabwe
Authors: Mutapurwa P , Mlambo T , Mavindidze E
Published: August 2022

Background: Sensory processing is a key component in the development of children. We sought to compare the sensory processing problems experienced by children (6-10 years) with and without autism in Harare, Zimbabwe.

Methodology: A quantitative cross-sectional study was done at public hospitals, non-profit organisations and urban public primary schools. Sensory processing abilities of children were assessed using the Short Sensory Profile (SSP) and compared between those with autism and those without, using Multivariate Analysis Of Variance (MANOVA). Ethical approval was granted and participants were voluntary.

Results: Seventy-four primary caregivers and their children participated in the study (40 for typically developing and 34 for those with autism). The overall mean age of the children was 8.1 years (SD 1.2), children with autism were older (mean 8.2 years SD 1.2) but not attending school. Those without autism were purposively matched for gender while there were more males (61.8%) than females among children with autism. Over 95% of children without Autism Spectrum Disorders (ASD) were rated as displaying normal sensory processing skills in all domains except for movement sensitivity where a quarter did not display typical performance. This was in contrast to less than half of children with ASD who displayed normal sensory processing domains. The only exception was visual/auditory acuity in 70.6% of children with ASD displayed normal sensory processing skills. There was a statistically significant difference in sensory processing skills between children with and without ASD in all domains (p=<0.01) with those with ASD displaying poorer performance.

Conclusion: Children with autism performed poorer than their typically developing peers on the SSP. The areas in which these children experience greatest impairment need to be targeted in interventions and caregivers should be equipped to address some of these problems.
Effectiveness of Strategies Used in Developing Accuracy and Coherence in Writing among Public Primary School Pupils in Namtumbo District, Tanzania
Authors: Ambrossy Lukuwi Legnath , Jacob Seni Abdallah
Published: August 2022

This study qualitatively explored the effectiveness of the strategies used by teachers in developing writing accuracy and coherence among public primary school pupils in Nantumbo District, Tanzania. It used the case study design involving the population of 736 purposefully sampled individuals including 16 teachers and 720 pupils from eight (8) schools in Namtumbo District Council. The study used classroom observation, focus group discussion, classroom continuous assessment and documentary review in data collection. Content analysis was adopted to analyses data and the findings revealed that teachers used various strategies in teaching how to write alphabetical letters including scaffolding, brief explicit lessons, alphabetic order, songs and teaching aids. It was further found out that some of these strategies such as using a talk-chalkboard strategy to teach punctuation marks were not effective to scaffold pupils and make them master writing. The study recommends teachers to use interactive strategies to enhance students’ acquisition of the writing skills.

Occupational risk factors and their impact on migration of radiographers from KwaZulu-Natal, South Africa
Authors: Thambura Julius Muchui , Swindon Lynda
Published: August 2022

Radiography is one of the allied healthcare professions known to be stressful. It is often associated with long working hours, ethical dilemmas, high patient demands and frequent disruptions from ancillary departments, which are all known to result in negative physical and psychosocial effects that may motivate migration. In this context, migration means; leaving one health sector to seek employment in another (i.e. private and public), resignation to join other professions or moving to a foreign country to practise radiography. The aim of this study was to identify occupational-risk factors that contribute to the migration of radiographers in order to provide input for mechanisms that can be put in place to alleviate the negative physical and psychosocial effects identified, thereby improving staff wellbeing and service delivery in KwaZulu-Natal. A cross-sectional, quantitative study, using a questionnaire as the data collection instrument was employed. The study targeted three categories of respondents: radiographers who left the profession (n=19), those who emigrated (n=29) and those who were employed in KwaZulu-Natal (KZN) (n=300). The results revealed that of the 348 participants, 221 (63 %) responded. The ages ranged from 19 to 60 (mean 39) years. The common negative occupational risk factors found across the three categories of radiographers included headaches, neck pain and spasms, lower back pain, knee pain and painful feet. The negative psychosocial effects identified were; job dissatisfaction, anxiety, stress, insomnia, depression and a sense of isolation. The study revealed that the identified occupation-related risk factors resulted in negative physical and psychosocial effects that could contribute to the migration of KZN radiographers. The introduction of employee assistance programmes and improved reporting systems are recommended to reduce the negative impact of occupation-related factors on radiographers and thereby improve staff wellbeing and reduce migration.

An observational examination of houses built under the ``Breaking New Ground`` housing policy of South Africa

Published: August 2022

The aim of the study was to examine the physical condition of houses built under the ``Breaking New Ground`` scheme and the environment that surround the residential areas. The Breaking New Ground housing plan seeks to provide housing to low-income groups in South Africa. The housing structures were examined in accordance with the ``Breaking New Ground`` housing policy, the Constitution of South Africa and the Freedom Charter. The study was qualitative in nature and an observational method was used to collect data. The study examined the physical condition of 45 housing units and their surroundings. The observational examination indicated that most of the residential units had structural defects and the environment was not conducive to the promotion of health and wellbeing among housing beneficiaries and their families. The design and aesthetic appeal of the houses was distorted by poor workmanship as they presented with inherent flaws. It was observed that the location of some of the housing clusters was isolated and far from places of work and the transport network was not efficient. Recommendations include improved quality control, aesthetic appeal and durability of housing units constructed under the Breaking New Ground housing scheme in South Africa.

An assessment of psychosocial and health risks associated with shift work in a South African manufacturing context
Authors: Mhlongo Philisiwe , Gabela Sibusiso Derrick , Reddy Poovendhree
Published: August 2022

Shift work is a necessity to ensure continuous and optimized operations in different occupational scenarios. However, there are numerous adverse effects associated with working shifts. This study is aimed at evaluating the psychosocial and health risks associated with working shifts in a manufacturing context in South Africa (SA). A cross sectional design using a modified form of the validated Standard Shift Work Index (SSI) questionnaire was used to collect quantitative data. Most participants were considered to be in good health, however they reported health complaints relating to swollen feet, weight gain, loss of appetite and gastrointestinal disorders. In addition, participants reported that their domestic lives were somewhat affected (45%) and their social lives were adversely affected (47%) by working shifts. Shift work experience (11 to 20 years) was also found to be significantly associated with more time for both social (OR = 0.10; 95% CI = 0.03; 0.30) and domestic activities (OR= 0.25; 95% CI = 0.11; 0.57; p < 0.05) compared to those with less experience. This may be attributed to the healthy worker survivor effect; it is likely that shift workers with longer working experience have developed practical coping strategies to mitigate some of the problems related to shift work.

Women and Discipleship in the Gospels
Authors: Mensah Augustine M.
Published: August 2022

Some reading the canonical Gospels, namely, the Gospels of Matthew, Mark, Luke and John are inclined to think that the disciples Jesus called were all men or males because whether it is the names of the apostles or a pronoun used about them, it is either a man’s name or masculine gender. It is a situation that tends to lead some Christian churches to prefer having only male ministers or pastors. The author of this paper argues that the notion or idea is a presentation of the first three Gospels but not the Fourth. The Fourth Gospel presents not only men but also women as disciples of Jesus.
What is the Problem with Stabilization Clauses in Petroleum Agreements?
Authors: Nalule Victoria R.
Published: August 2022

International Oil Companies (IOCs) continue to invest in countries which do not have stabilization clauses. Why is this so? What is the essence of these clauses? One of the curiosities of stabilization clauses in petroleum agreements, is that most developed countries will not offer them to investors. So, why do developing countries with stable political, fiscal and regulatory climate offer them? Additionally, history shows that these stabilization clauses have not deterred host governments from expropriating petroleum investments. While governments may be able to make commitments of their own, as a matter of national sovereignty they may not be able to bind the legislative competence of the State into the future. These concerns are the main driver behind this article, which is influenced by the various questions asked by policymakers in the Global South on the importance of stabilization clauses for the sustainable development and management of natural resources.

Oil Spills in the Niger Delta-Does the Petroleum Industry Act 2022 Offer Guidance for Solving this Problem?
Authors: Ele Millicent
Published: August 2022

Oil exploration and production in the Niger Delta have resulted in massive oil spills and lasting environmental damage to the region. This article critically examines the legal and regulatory dimensions of this problem. It looks at the general statutory provisions governing oil spills in the Niger Delta to see whether there are gaps and deficiencies in the existing laws and policies which cause or exacerbate oil spills in the region. It further looks at the implementation and enforcement of the laws, particularly the effectiveness or lack thereof of the polluter-pays principle, adequacy of funding for environmental remediation, issues relating to standard setting and ministerial discretion, as well as the issues associated with the security problems in the Niger Delta. The article concurrently reviews relevant sections of the newly enacted Petroleum Industry Act (PIA), 2021 to see whether it offers guidance for solving the endemic problem of oil spills in the Niger Delta. It is concluded that poorly developed laws, and weak institutions that result in weak implementation and enforcement protocols remain largely to blame for the problem of oil spills in the Niger Delta. It also discusses how the PIA can be strengthened to address persisting gaps in the design and implementation of oil spill responses in Nigeria.

Studies on African Crambidae I- a new genus and species from Africa (Pyraloidea: Crambidae: Spilomelinae)
Authors: Maes Koen V.N.
Published: August 2022

A new genus and species is described from a series of specimens collected in the broad vegetation band from Mali to the Kenyan coast. It is placed close to Metasia (Spilomelinae) because of the bilobed uncus in the male genitalia. It seems to be linked to drier habitats.
