Values, Islamic Religion, Islamic Religious Education, Covid, Film Analysis. The message in the film, of course, there are positive and negative. Many people can easily catch the message from the film they watch, but many also find it difficult because they think that films are just entertainment. Many criticize someone who is analyzing a film, because for them it is a waste of time. It's actually not wrong, because everyone has the right to determine his own way how he will process the film. This type of research is descriptive qualitative. The subjects of this thesis research are: Film. This qualitative research method uses data collection techniques, namely: Observation and Documentation. The results of the study show that we can take some important messages contained in this film, so that we can understand that someone making a work like a film has a purpose that we need to understand.

Distributing human leukocyte antigen (HLA) database in histocompatibility: a shift in HLA data governance
Authors: Sayadi Sirine , Douillard Venceslas , Vince Nicolas , Südholt Mario , Gourraud Pierre-Antoine
Published: November 2022

Aim: Human leukocyte antigen (HLA) population genetics has been a historical field centralizing data resource. HLA genetics databases typically facilitate access to frequencies of allele, haplotype, and genotype format information. Among many resources, the Allele Frequency Net Database (AFND) is a typical centralized repository that allows users to research and analyze immune gene frequencies in different populations around the world. With the massive increase in medical data and the strengthening of data governance laws, the proposal for a new distributed and secure model for the historical centralization method in population genetics has become important. In this paper, a new model of HLA population genetic resources, an alternative distributed version of HLA databases has been developed. It allows users to perform the same research and analysis with other remote sites without sharing their original data and monitoring data access.
Methods: This new version uses the Master/Worker distributed model and offers distributed algorithms for the calculation of allelic frequencies, haplotypic frequencies and for individual genotypic calculations. The new model was evaluated on a distributed testbed for experiment-driven research Grid’5000 and has obtained good results of accuracy and execution time compared to the original centralized scheme used by researchers.
Results: The results show that distributed algorithm applied to HLA population genetics resources enables usage control and enables enforcing the security framework of the data-owning institution. It gives the same results for all counting methods in population immunogenetics. With the same frequencies’ estimations, it yields a much quicker computation time in many cases, in particular for large samples.
Conclusions: Distributing previously centralized resources is an interesting perspective enhancing better control of data sharing.

Keberpihakan Terselubung Pegawai Non Aparatur Sipil Negara dalam Pilkada (Studi Kasus di Kota Probolinggo)
Authors: Rohim Rohim , Supriyadi Ibnu
Published: November 2022

Artikel ini mengkaji netralitas pegawai non Aparatur Sipil Negara (ASN) dalam Pemilihan Kepala Daerah (Pilkada) dan bagaimana Badan Pengawas Pemilu Kota Probolinggo memberikan respon terhadap isu tersebut. Meskipun secara formatif dan legal formal pegawai non ASN tidak terbukti melanggar netralitas, namun dibalik layar beberapa bukti menunjukkan mobilisasi pegawai non ASN untuk mendukung salah satu kandidat kepala daerah. Dengan menggunakan hasil wawancara terhadap sumber-sumber di Kota Probolinggo, penelitian ini menemukan faktor penyebab pegawai ASN mendukung salah satu kandidat dan ditemukannya pola mobilisasi oleh pegawai non ASN sebagai agen dalam meraih suara pemilih. Pegawai non ASN memobilisasi kekerabatan dalam meraup suara pemilih. Sayangnya sikap Badan Pengawas Pemilu Kota Probolinggo berkesimpulan hal tersebut tidak melanggar aturan karena tidak adanya aturan yang melarang pegawai non ASN ikut politik praktis dalam pelaksanaan Pemilu maupun Pilkada. Adanya praktik mobilisasi menunjukkan bahwa pegawai non ASN lihai dalam memberikan dukungan kepada salah satu calon tertentu tanpa terjerat aturan netralitas dari Badan Pengawas Pemilu Daerah.

Vegatations: Truth and Disguise from Bertolt Brecht to Paul Celan
Authors: Serrano Pedro
Published: November 2022

This essay works on the links and shifts between Paul Celan's poem "A Leaf. Treeless" and Bertolt Brecht's "To Those Born After" as displaced expressions of the simultaneous needs of assertion and perils of silencing faced by poetry in dark times. It works out the way in which both poets, in their particular ways and attending their own obstacles, present as a question what ideology tends to silence and display as a paradox the communal and individual claims to be alive through the action of poetry. It moves from T. S. Eliot's vegetal similes from his Virginia lectures of 1933 included in After Strange Gods, to Joseph Brodsky Nobel Prize lecture of 1987 in which he discusses Theodor Adorno's questioning of the relevance of poetry after Auschwitz. It also analyzes the way in which plants and human beings relate and interact based on their biological differences and equivalences both as individuals and as communities, and how this has been used both as metaphor and ideology, either to liberate, as it happens rhetorically in Brecht and Celan or to reinforce forbidences through ideological impositions, as it happens in Adorno. It goes back to T. S. Eliot's It traces the presence of plants as a metaphor for the human being in metaphors and ideology. KEYWORDS: Paul Celan, Bertolt Brecht, Poetry, Plants, Translations.

Authors: ER Füsun , YALMAN Yıldıray
Published: November 2022

This paper presents an application of multi-objective non-dominated sorting genetic algorithm with a modified chromosome encoding for histogram shifting-based multiple reversible data hiding scheme in neuroimages which aims to minimize distortion and maximize capacity. The modified chromosomes encoding scheme is designed according to the zero-bin characteristic of the intensity histogram of the structural magnetic resonance imaging scans of human brain. The experiments of this study is designed to assess the effect of non-dominated sorting for multi-objective optimization compared to Euclidian distance, the convenience of modified chromosome encoding scheme for medical images compared to non-medical images. The performance of the proposed method has been measured in terms of the peak signal-to-noise ratio (PSNR) for image quality and the bits per pixel (bpp) for capacity assessments. The experimental results show that the proposed method is better than its counterparts.

Manajemen merupakan aspek penting di dalam melakukan pelayanan jemaat. Sistem manajemen yang baik, bersih dan memiliki batasan-batasan wewenang yang jelas akan berpengaruh terhadap perkembangan jemaat. Dalam kenyataannya masih banyak ditemukan pola manajemen pelayanan yang buruk dan berakibat kepada hancurnya pelayanan jemaat dan tidak sedikit yang berakhir pada kisah tragis dari sang pelayan. Penyalahgunaan wewenang dan perlakukan moral yang tidak sesuai dengan ajaran yang terdapat di dalam Alkitab justru menjadi penyebab runtuhnya sebuah bangunan pelayanan jemaat. Untuk itu diperlukan sebuah  pedoman etika di dalam pelayanan jemaat sangat diperlukan untuk mengantisipasi segala bentuk kesewenang-wenangan yang terjadi di dalam pelayanan jemaat. Penelitian ini memberikan sebuah pedoman praktis bagi setiap jemaat untuk membuat sebuah dokumen etika yang harus ditaati oleh seluruh pemangku kebijakan dan pelaksana dalam sebuah pelayanan jemaat. Pedoman yang didasarkan kepada eksegesis teks 1 Petrus 5:1-4 dengan melakukan studi silang dengan beberapa dokumen pedoman etika dan kepatuhan yang dikeluarkan oleh perusahaan-perusahaan berkelas dunia. Dengan melakukan studi literatur dan focus group discussion, terbentuklah sebuah pedoman praktis yang dapat dijadikan acuan bagi jemaat untuk melakukan manajemen pelayanan jemaat yang bersih, sopan dan berkeadilan.
Analisis Grammatical-Exegetical Wahyu 3:20 dan Implikasinya Terhadap Relevansi Penggunaan Wahyu 3:20 Dalam Model Penginjilan Kontemporer
Authors: Purba Jhon Leonardo Presley , Waruwu Riang Hati , Manullang Amran , Rimun Robinson
Published: November 2022

Revelation 3:20 is a popular verse that used in contemporary evangelism to encourage the unbelievers to believe in Jesus. Nevertheless, is such usage relevant to the text and context of Revelation 3:20? Using a descriptive qualitative research form with an interpretative model of Grammatical-Exegetical analysis, the aims of this study is to find the theological meaning of Revelation 3:20 and its implications for the relevance of the using of Revelation 3:20 in contemporary evangelistic models. The results of this study conclude that based on the text and context of Revelation 3:20, the usage of this verse in contemporary evangelism toward unbelievers is irrelevant to the text and its context, the meaning of "the door that knocks" by Jesus in this verse does not refer to the door of an individual's heart who do not know Christ but the "spiritual door" of the church or community of believers who have known Christ who are asked to repent from self-satisfied and lukewarmness because of physical wealth, this is also the true theological meaning of Revelation 3:20 which is very relevant with the moral and spiritual state of the church in the modern era which also tends to be self-satisfied and spiritually lukewarm so the implication for believers and the church today is the church need to repent from its self-satisfied, spiritual lukewarmness and "open its doors" for Christ so that Christ can come in to His church and live with His church.  Wahyu 3:20 merupakan ayat yang populer digunakan dalam penginjilan kontemporer untuk mendorong individu yang belum percaya menjadi percaya kepada Yesus. Namun, apakah penggunaan demikian relevan dengan teks dan konteks Wahyu 3:20? Menggunakan bentuk penelitian kualitatif deskriptif dengan model penafsiran analisa Grammatical-Eksegetical, penelitian ini bertujuan untuk menemukan makna teologis Wahyu 3:20 dan implikasinya terhadap relevansi penggunaan Wahyu 3:20 dalam model penginjilan kontemporer. Hasil penelitian ini menyimpulkan bahwa berdasarkan teks dan konteks Wahyu 3:20, penggunaan ayat ini dalam penginjilan kontemporer terhadap orang yang belum percaya tidak relevan dengan teks dan konteksnya, makna “pintu yang diketuk” oleh Yesus dalam ayat ini bukan merujuk pada pintu hati seorang individu yang belum mengenal Kristus melainkan “pintu rohani” gereja atau komunitas orang percaya yang telah mengenal Kristus yang diminta untuk bertobat dari berpuas diri dan suam-suam rohani karena kekayaan jasmani, inilah juga yang menjadi makna teologis yang sebenarnya dari Wahyu 3:20 yang sangat relevan dengan keadaan moral dan kerohanian gereja di era modern yang juga cenderung berpuas diri dan suam-suam secara rohani sehingga implikasinya bagi orang percaya dan gereja masa kini adalah agar gereja bertobat dari sifat berpuas diri, suam-suam rohani dan “membuka pintunya” bagi Kristus agar Kristus dapat datang kepada gereja-Nya dan tinggal bersama dengan gereja-Nya.
Orbital Flips Caused by the Eccentric Von Zeipel–Lidov–Kozai Effect in Nonrestricted Hierarchical Planetary Systems
Authors: Huang Xiumin , Lei Hanlun
Published: November 2022

The eccentric von Zeipel–Lidov–Kozai effect is widely applied to diverse astrophysical settings. In the restricted hierarchical three-body system, the topic of orbital flips has been extensively studied. However, it is far from being understood for nonrestricted circumstances. In this work, the dynamics of orbital flips are investigated under the Hamiltonian model at the octupole-level approximation for nonrestricted hierarchical planetary systems, where the outer planet is more massive than the inner one. Numerical distribution of flipping orbits shows that there are three major flipping regions, distributed in low-, intermediate-, and high-eccentricity spaces. Poincaré sections indicate that those islands of libration centered near i
tot = 90° can lead to orbital flips. Thus, we refer to the behavior of orbital flips as a resonance phenomenon. From this viewpoint, dynamical models of orbital flips can be described by a separable Hamiltonian, which can be treated by a means of perturbation theory. The resonant model for orbital flips is formulated based on the adiabatic invariant approximation and then phase portraits are generated by plotting level curves of adiabatic invariants with the given Hamiltonian. By analyzing phase portraits, analytical boundaries of libration and circulation zones causing orbital flips are obtained. As expected, the numerical and analytical conditions that allow orbits to flip agree well with each other. The phenomenon of orbital flips in nonrestricted hierarchical problems can be well understood with the help of dynamical structures of secular resonance.
An X-Ray Proper-motion Study of the Large Magellanic Cloud Supernova Remnant 0509-67.5

Published: November 2022

We present a third epoch of Chandra observations of the Type Ia Large Magellanic Cloud Supernova remnant 0509-67.5. With these new observations from 2020, the baseline for proper-motion measurements of the expansion has grown to 20 yr (from the earliest Chandra observations in 2000). We report here the results of these new expansion measurements. The lack of nearby bright point sources renders absolute image alignment difficult. However, we are able to measure the average expansion of the diameter of the remnant along several projection directions. We find that the remnant is expanding with an average velocity of 6120 (4900–7360) km s−1. This high shock velocity is consistent with previous works, and also consistent with the inference that 0509-67.5 is expanding into a very low density surrounding medium. At the distance of the LMC, this velocity corresponds to an undecelerated age of 600 yr, with the real age somewhat smaller.
A vegetation classification and description of Telperion Nature Reserve, Mpumalanga, South Africa
Authors: Brown Leslie R. , Magagula Itumeleng P. , Barrett Alan S.
Published: November 2022

Aims: This study identified, classified and mapped the different plant communities found on the Telperion Nature Reserve. Study area: Telperion Nature Reserve, Mpumulanga, South Africa. Methods: Using a 1:10,000 aerial photograph, Telperion was delineated into homogenous physiognomic-physiographic units. 294 sample plots (100 m2) were placed in a randomly stratified manner within identified homogenous units. Plant species present in sample plots were recorded and allocated a modified Braun-Blanquet cover abundance scale value. Sample plot data were captured into TURBOVEG and exported for editing, classification and processing in JUICE. A modified TWINSPAN classification was applied to derive a first approximation of the plant communities in a synoptic table that was refined using Braun-Blanquet procedures. Species were manually arranged into groups. Diagnostic, constant and dominant species were statistically determined from the synoptic table. Threshold values for fidelity, frequency and canopy cover were set and a final phytosociological table was produced for describing the plant species composition for the different plant communities. Results: 22 plant communities were identified for Telperion. Five were major communities, 14 were sub-communities and 13 were variants. The five major plant communities were Cyathea dregei–Ilex mitis ravine woodland, Paspalum urvillei–Phragmites australis valley bottom wetland, Diospyros lycioides–Combretum erythrophyllum riparian woodland, Eragrostis curvula–Seriphium plumosum midslope plateau grassland, and Combretum molle–Englerophytum magalismontanum rocky ridge woodland. The plant communities were also described and mapped. Conclusions: The classification, description and mapping of Telperion’s vegetation provides a basis for management decision making about wildlife stocking rates, fire planning, and vegetation management. Findings indicate that Bankenveld vegetation is heterogeneous with a variety of habitats including woodland and grassland components. Telperion has a variety of plant communities and a high plant species diversity, making it a reservoir for plant species and an important conservation area.

Molecular and biometric data on Carabus (Macrothorax) morbillosus Fabricius, 1792 (Coleoptera, Carabidae) from Mid Mediterranean areas
Authors: Colomba Mariastella , Lo Verde Gabriella , Liberto Fabio , Gregorini Armando , Sparacio Ignazio
Published: November 2022

The present study was carried out using molecular and biometric data of Carabus (Macrothorax) morbillosus from mid-Mediterranean areas to determine additional information on basal relationships among its representative subspecies. To this aim, two different kinds of approach were employed, including a morphometric analysis of four morphological parameters (i.e., elytra length, elytra width, pronotum length, pronotum width) of 128 specimens, and a Bayesian genetic analysis of 44 cytochrome oxidase subunit I (COI) partial sequences (i.e., 38 examined for the first time and six retrieved from GenBank database). Representative populations of C. (M.) morbillosus were sampled in four countries, namely Italy, Malta, Spain, and Tunisia. The present findings support the validity of four C. (M.) morbillosus subspecies, specifically C. (M.) m. alternans, C. (M.) m. bruttianus, C. (M.) m. constantinus, and C. (M.) m. macilentus, and redefine these subspecies’ distributions. Notably, within the C. (M.) m. constantinus clade, two (i.e., Sardinia/Tuscany and Lampedusa) out of the three subgroups appear as homogeneous geographical groupings.
A new species of feather-tailed leaf-toed gecko, Kolekanos Heinicke, Daza, Greenbaum, Jackman, Bauer, 2014 (Squamata, Gekkonidae) from the poorly explored savannah of western Angola
Authors: Lobón-Rovira Javier , Conradie Werner , Baptista Ninda L. , Vaz Pinto Pedro
Published: November 2022

We here describe a new species of feather-tailed leaf-toed gecko, Kolekanos, from southern Benguela Province, Angola, based on morphological and osteological evidence, supported by phylogenetic analysis of mitochondrial data. The new species adds to the rapidly growing and newly-recognised endemic biodiversity of Angola, doubling the number of Kolekanos species, breaking the pattern observed within other closely-related African members of a clade of circum-Indian Ocean leaf-toed geckos – Ramigekko, Cryptactites and Afrogecko – all of which are presently monotypic. The new species is easily distinguished from K. plumicaudus, based on spine-like (as opposed to feather-like) scales on the margins of the original tail. Phylogenetic analyses also recovered the new taxon as monophyletic, with a well-supported sister relationship to K. plumicaudus, from which it differs by a substantial 24.1% NADH-dehydrogenase subunit 2 mitochondrial gene uncorrected p-distance.

Published: November 2022

Background/Aims: Acute upper gastrointestinal (UGI) bleeding is a significant emergency situation with a mortality rate of 2% to 10%. Therefore, initial risk stratification is important for proper management. We aimed to evaluate the role of contrast-enhanced multidetector computed tomography (MDCT) for risk stratification in patients with acute UGI bleeding in the emergency room (ER).Methods: This retrospective study included patients with UGI bleeding in the ER. Glasgow-Blatchford risk score-computed tomography (GBS-CT) was assessed using a combination of GBS and the MDCT scan scoring system.Results: Of the 297 patients with UGI bleeding, 124 (41.8%) underwent abdominal MDCT. Among them, 90.3% were classified as high-risk by GBS, and five patients died (4.0%). Rebleeding occurred in nine patients (7.3%). The high-risk GBS-CT group had significantly higher in-hospital mortality (10.5% in high-risk vs. 1.4% in moderate risk vs. 0% in low-risk, p = 0.049), transfusion amount (p < 0.001), and endoscopic hemostasis (p < 0.001) compared to the moderate- and low-risk groups.Conclusions: Adding MDCT scans to the existing validated prognosis model when predicting the risk of UGI bleeding in patients in the ER plays a significant role in determining in-hospital mortality, transfusions, and the need for endoscopic hemostasis.
Crises et capacité d’endettement public : la révolution financière anglaise aux XVII e et XVIII e siècles
Authors: Dockès Pierre
Published: November 2022

Un résultat remarquable qui n’empêcha pas le rapport « dette/PIB » de croître de façon vertigineuse jusqu’en 1815 au rythme des guerres avec la France. Entre 1688 (la Glorious Revolution ) et les années 1730-1740, l’Angleterre réussit à se doter d’une capacité d’endettement considérable. Cette révolution financière fut le nerf des guerres qui se succèdent jusqu’en 1815. Elle anticipe et prépare la révolution industrielle, l’expansion capitaliste et la domination britannique. La dette et le rapport « dette/PIB » vont pouvoir exploser au xviii e siècle, ce dernier dépassant 250 % en 1815. S’il y eut des secousses financières, le sterling et le crédit de l’État vont tenir et se consolider. L’article montre comment cela s’est réalisé : augmentation de la capacité à lever des impôts en relation avec la prise de pouvoir parlementaire, réforme monétaire accomplie dans la crise de 1694-1697, création de la Banque d’Angleterre pour soutenir la dette, politique de transformation de la dette en actions d’une compagnie coloniale, de cantonnement et de restructuration qui a donné lieu à la dérive spéculative majeure de la South Sea Bubble. Le contraste entre les xviii e et xix e siècles est spectaculaire. Après 1815, la domination britannique assurée, la priorité sera donnée à la baisse des prélèvements ; le montant de la dette ne sera réduit que tardivement et modérément. En revanche, grâce à la croissance, le rapport « dette/PIB » va s’effondrer. Jusqu’en 1914. Cela s’est fait dans les guerres perpétuelles, les conflits politiques. Le xix e siècle connaît une chute vertigineuse du rapport « dette/PIB », mais une baisse du montant de la dette seulement tardive et modérée. Classification JEL : N13, N40.
Vulnerability to Adverse Working Conditions in EU-15 Countries: Empirical Evidence over two Decades
Authors: Greenan Nathalie , Seghir Majda
Published: November 2022

Conformément aux objectifs européens d’une croissance et d’un marché du travail plus inclusifs, la question de la vulnérabilité des travailleurs occupe un pan essentiel de la politique économique et sociale européenne. Ce travail s’insère ainsi dans une réflexion visant à définir et à mesurer les différentes formes de vulnérabilité qui peuvent survenir et se développer dans le travail en Europe. Nous proposons un cadre conceptuel et méthodologique où la vulnérabilité est définie comme le degré d’exposition des travailleurs à des risques cumulés sur le lieu de travail, ayant des effets néfastes pour le bien-être et la santé. À cette fin, un indicateur de conditions de travail défavorables est proposé : il agrège des facteurs relatifs aussi bien à l’environnement – qu’il soit physique ou social – qu’au contenu et à l’organisation du travail (forte intensité du travail, faible complexité, horaires atypiques). Cet indicateur synthétique est ensuite utilisé pour calculer la probabilité pour un travailleur d’être exposé à une dégradation de ses conditions de travail. C’est cette probabilité qui mesure la vulnérabilité aux conditions de travail dégradées. Notre mesure est construite à partir des données provenant des cinq dernières éditions de l’enquête européenne sur les conditions de travail (EWCS). S’appuyant sur les techniques d’estimation en pseudo-panel, nos résultats montrent de grandes disparités de la vulnérabilité des travailleurs occupés au sein des quinze pays fondateurs de l’Union européenne JEL : C23, I31, J81

The air quality monitoring system is the most prominent tool for monitoring air pollution levels, especially in areas where forest fires often occur. The South Sumatra Province of Indonesia is one of the greatest contributors to haze events in Indonesia due to peatlands fires. It does not sufficiently possess a ground monitoring system to cover rural areas, and thus, delayed actions can result in severe air pollution within this region. Therefore, the aim of this current study is to analyze the distribution and classification of PM2.5 observed from 2019 to 2021 within the South Sumatra Province, Indonesia. The acquisition of PM2.5 data was from the Merra-2 Satellite with a spatial resolution of 0.5˚
× 0.625˚ and an hourly interval. The hierarchical cluster analysis (HCA) was applied in this study for the clustering method. The result of the study revealed that the daily mean of PM2.5 levels varied from 5.9±0.01 to 21.3±0.03 μg/m3. The study area was classified into three classes: high pollution areas (HPA), moderate pollution areas (MPA) and low pollution areas (LPA), based on the HCA method. The average level of PM2.5 observed in HPA was notably higher, at 16.8±0.02 μg/m3, followed by MPA and LPA. Furthermore, this study indicated that the highest level of PM2.5 was found during 2019, with a severe haze event in the study area due to the intensive burning of forests, bush and peatlands. As a whole, the output of this study can be used by authorities for air quality management due to forest fire events in a certain area.

Published: November 2022

In this paper, a new class of Cucker-Smale systems with distributed delays are developed from the measurement perspective. By combining dissipative differential inequalities with a continuity argument, some new sufficient criteria for the flocking dynamics of the proposed model with general communication rate, especially the non-normalized rate, are established. In order to achieve the prescribed pattern motion, the driving force term is incorporated into the delayed collective system. Lastly, some examples and simulations are provided to illustrate the validity of the theoretical results.

Authors: Kohnen Melanie E. S.
Published: November 2022

I examine how industry and fans reassessed the value of TV promotion in the form of activations—branded pop-up in-person experiences that promise immersion into storyworlds—as they transformed into online events during Comic-Con@Home in 2020 and 2021. I highlight the industry's expansion of first-party data collection from and tracking of fans in virtual activations.
Challenges and opportunities of centring the African voice in disability research
Authors: Ned Lieketseng Y. , Dube Kudakwashe , Swartz Leslie
Published: November 2022

In 2020, the African Network of Evidence to Action on Disability (also known as AFRINEAD) hosted its 10th conference in Cape Town. This paper synthesises inputs by the three authors as plenary addresses, particularly focusing on the challenges and opportunities of centring African voices in disability research. Our concern in this article is to engage with the question of exclusion as an issue not just in the everyday lives of people with disabilities but also in the world of ideas – the ideational space. We suggest that a reimagined disability study depends on the centring of African experiences, voices and knowledges. This is especially so as there are African concepts that are not rigorously pursued in research. African Renaissance thinking makes allowance not only for critically reflecting on the historical and contemporary constructs of disability but also for fashioning a higher civilisation in which people with disabilities can exist within society as worthy and valued human beings.
The development of the Quality of Translation and Linguistic Equivalence Checklist
Authors: Smith Mario R. , Adams Nuraan , Munnik Erica
Published: November 2022

The International Test Commission (ITC) established guidelines for test adaptations. The ITC encourages the adaptation of locally developed measures with proven validity. A good quality translation process ensures that the same meaning is conveyed from the source to the target language. Through test adaptation, researchers focus on cultural differences between the source and the target language to maintain linguistic equivalence. Research involving adaptation has systematically failed to report on the rigour of the translation process and to make translation part of the empirical process. The ITC guidelines are generally referred to; however, the assessment of the quality of translations and the process of establishing linguistic equivalence remain an important research focus. This study reports on the development of the Quality of Translation and Linguistic Equivalence Checklist (QTLC). The construction of the QTLC was based on ITC guidelines. The QTLC consists of two sections, translation and linguistic equivalence, and produced section scores with accompanying quality descriptions. The draft instrument was presented to three independent reviewers. Once feedback was incorporated, the QTLC was piloted in an ongoing study on the translation of the E3SR. Two reviewers applied the checklist, and inter-rater reliability was established. The Kappa statistic (0.78) tested significant at a 0.00 alpha level, indicating substantial agreement between the raters on the quality of the translation process and equivalence. Four items were identified as functioning differently and were subsequently revised. The QTLC appears to be a robust checklist assessing the quality of translations and the process of establishing linguistic equivalence.

children. Their needs are not met. There is lack of support for caregivers and no existing conceptual framework of support. There was therefore a need to develop a conceptual framework of support for caregivers.Objectives: The purpose of this study was to develop a conceptual framework of support for caregivers of children diagnosed with intellectual disabilities in the Gauteng province.Method: Three phases were followed: an empirical phase, a classification of concepts and a development phase. A conceptual framework was developed based on the results of the empirical phase, after concepts were classified.Results: The conceptual framework of support for caregivers of children diagnosed with intellectual disabilities in the Gauteng province was developed, consisting of six components, namely agents, recipients, context, procedures, dynamics and terminus.Conclusion: A framework will guide all stakeholders on how to support caregivers of children diagnosed with intellectual disabilities in the Gauteng province.Contribution: The framework serves as a guide for future studies aiming at developing support programmes and models for caregivers, and further provide guidance on how caregivers can effectively be supported when used in mental healthcare institutions.

Published: November 2022

Background: Idiopathic causes of infertility is associated with oxidative stress. Antioxidants are known to scavenge the excessive production of reactive oxygen species (ROS). Green tea (Camellia sinensis) contains polyphenols that enhance its antioxidant potential.Aim: This study focused on the impact of aqueous green tea extract on normozoospermic human spermatozoa.Setting: Department of Medical Biosciences, University of the Western Cape (UWC), South Africa.Methods: Semen samples obtained using masturbation method following three to five days of sexual abstinence from consenting men (n = 59) at the University of the Western Cape (UWC) were liquefied and analysed. Normozoospermic samples were selected according to the World Health Organization (WHO) 5th guideline. Thereafter, semen samples (7.5 × 106 /mL) were washed in human tubular fluid (HTF; 10 min at 300 ×g) and exposed to aqueous extracts of green tea (0 μg/mL, 0.4 μg/mL, 4 μg/mL, 40 μg/mL, 405 μg/mL) for 1 h with various sperm parameters analyzed. Human tubular fluid supplemented with bovine serum albumin (HTF-BSA; 10%) served as control.Results: Sperm motility, reactive oxygen species production, across some reaction and deoxyribonucleic acid (DNA) fragmentation decreased significantly, particularly at the highest concentration (405 μg/mL; p 0.001). A substantial increase in the percentage of viable spermatozoa and those with intact mitochondrial membrane potential (MMP) were observed (p 0.001).Conclusion: Aqueous extract of green tea prolonged sperm viability and MMP while reducing sperm intracellular ROS production, capacitation and across some reaction and DNA fragmentation, and may be attributed to its antioxidant potential. However, a high concentration of the extract appears to be detrimental to the functioning of human spermatozoa.
How did primary health care in Beira experience Cyclone Idai?

Published: November 2022

Beira, the biggest city of Mozambique’s Sofala province, was struck by Cyclone Idai on 14 March 2019, with devastating impacts. The floods along with the cyclone destroyed road infrastructure and health facilities and disrupted primary health care (PHC) service delivery. In addition, destruction of farmland and food stocks resulted in malnutrition; the abundance of water fostered the reproduction of mosquitos, exacerbating the burden of malaria; and problems with water and sanitation led to epidemics of cholera. The exact role and contribution of human-induced climate change is very difficult to quantify, but there is little doubt that climate change is driving more frequent and severe cyclones, such as Idai. Considering the current climatic changes, it is expected that climate hotspots such as Beira will only experience more frequent extreme weather events. In these settings, with high risks but low adaptive capacity, dedicated efforts are required to strengthen PHC with a focus on preparedness for disasters. This should entail community awareness and education, strengthening infrastructure and service provision, as well as collaboration with important stakeholders across other sectors.Contribution: Using a case study approach, this article contributes climate resilient PHC for better preparedness to service continuity.
