Void filling and water sealing in a decline in the Kalahari Manganese Field
Authors: Serepa I. , Steenkamp N.C.
Published: April 2022

Investigations were conducted to determine the condition and stability of the existing decline at a mine in the Kalahari Manganese Field, Northern Cape Province, South Africa. During the inspection of the decline, voids were identified behind the concrete lining on the hangingwall and sidewalls over a total linear distance of 230 m. The voids did not provide confinement and, as a result, self-mining was occurring behind the lining. Water was flowing into the decline, over a total linear distance of 100 m, at areas where the decline intersected incompetent rock units, causing softening of the concrete lining and deterioration of the surrounding rock mass. Further damage to the concrete lining was caused by expansion and contraction of the wet red clay unit. Remedial work comprised void filling and water sealing to prevent further deterioration of the decline and ensure that it remained operable for the remainder of the life of mine. Void filling was accomplished by drilling rows of holes along the decline to access the voids and filling the voids with foam. This was followed by the sealing with polymer fluids. Telescopic pipes were also installed to allow water to drain off. A visual inspection was conducted and check-holes were drilled to assess the quality of the remedial work. The void filling material had penetrated cracks in the concrete lining, and areas where voids were intersected by check-holes were re-filled. Additional holes were drilled to re-seal areas that were still wet. The remedial work was completed successfully, as all voids were filled and stability achieved without compromising the concrete lining. The ingress of groundwater was also reduced to some residual dampness.

Authors: BULUT Cafer , KUBİLAY Ayşegül
Published: April 2022

Bu çalışmada, bakır sülfatın (CuSO4.5H2O) farklı konsantrasyonlarının gökkuşağı alabalıklarının (Oncorhynchus mykiss) solungaç, karaciğer ve kas dokusu üzerindeki histolojik etkisi araştırılmıştır. Çalışmada kontrol grubu, 0.5 mg/L (24 saat), 3 mg/L (18 saat), 500 mg/L (1-2 dakika) bakır sülfat konsantrasyon grupları uygulanmıştır. Biyodeneyde ortalama ağırlığı 150 g olan 40 adet balık kullanılmıştır. Histopatolojik bulgular içinde her deney grubundan 5 balık kullanılmıştır. Dokular 24 saat boyunca % 10 formalin çözeltisi ile sabitlenmiştir. Doku örnekleri, histolojik protokol standardı kullanılarak parafine gömülmüş, kesitler 5 µm kalınlıkta kesilmiş, cam slaytlar üzerine monte edilmiş, hematoksilin ve eozin (H&E) ile boyanmış ve boyanan bölümler ışık mikroskobu altında incelenmiştir. Karaciğerde sinuzoidal boşluklar, venalarda konjesyon, vakuoler ve parankim dejenerasyon, damarlarda hasar ve hepatositlerde dejenerasyon görülmüştür. Kas dokularında dejenerasyon, nekroz (miyofaji), inflamatuar selüler infiltrasyon görülmüş, solungaç lamellalarında, pilar ve epitel hücrelerde dejenerasyon, interlamellar alanlarda lenfoid ve mononükleer hücre infiltrasyonu, epitelyum hücrelerde nekroz gözlenmiştir. Çalışmada, 3 mg/L bakır sülfat konsantrasyonunun balıklar için çok zararlı olduğu belirlenmiştir. Zira yüksek konsantrasyonlarda bakır sülfatın özellikle balıkların solungaç ve dokularını olumsuz yönde etkilediği belirlenmiştir. Kısa süreli kullanımlarda 500 mg/L ve uzun süreli banyoda ise 0,5 mg/L tercih edilebilir. Çalışmada, bakır sülfatın su ürünleri yetiştiriciliğinde bilinçli ve ihtiyaç dâhilinde kullanılması gerektiği sonucuna varılmıştır.

Prescribing pattern of analgesics in Colombia. Are there differences between capital cities and municipalities? v1
Authors: Machado Alba Jorge
Published: April 2022

Background. Analgesics provide multiple clinical benefits, but they are not without risks. Objective. To compare the outpatient prescribing pattern of analgesics between cities and municipalities in Colombia and to identify the variables associated with prescribing opioid analgesics. Methods. A cross-sectional study that identified the prescription of analgesics for outpatient use from a population database of 8.5 million Colombians. A descriptive, bivariate and multivariate analysis was performed. Results. A total of 573,248 patients were identified who had received prescriptions for some analgesic; they had a mean age of 46.5±23.6 years, and 65.7% were women. The most commonly prescribed analgesics were nonopioid analgesics, antispasmodics and opioid analgesics. The average milligram equivalent of morphine was higher in capital cities than in municipalities. Age ≥65 years (OR:2.60, 95%CI:2.54-2.67), being male (OR:1.09, 95%CI:1.07-1.11), dispensing in cities (OR:2.25; 95%CI:2.20-2.30) and suffering from chronic pain (OR:13.25; 95%CI:10.89-16.14) were associated with an increased risk of receiving an opioid analgesic. Conclusions. Differences were found in the prescription of analgesics between capital cities and municipalities. The use of opioids does not appear to be in line with the recommendations for clinical practice, and they were mainly prescribed for elderly men with chronic nononcological pain and for residents of capital cities.
DNA extraction and Nanopore library prep from single wild-caught drosophilids v1
Authors: Y Kim Bernard
Published: April 2022

We have been assembling the genomes of many Drosophila species. This protocol fork allows for the sequencing of single wild-caught flies using Nanopore MinION sequencers, in contrast to our previous protocol that originally used gDNA extracted from tens or hundreds of flies from an inbred line. While read lengths are not nearly close to what we were seeing before, libraries range from 2-10kb read N50 and typically produce genome assemblies with contig N50 >1 Mbp. The protocol for ultra-long read sequencing from large pools of flies can be found here: dx.doi.org/10.17504/protocols.io.bdfqi3mw Please cite the associated paper if you use this protocol: https://doi.org/10.7554/eLife.66405 An update to the original paper that includes many single wild-caught fly genomes is in progress.

Sürdürülebilirlik Uygulamalarının Sosyal Medya İletişiminde Kullanımı: Bankacılık Sektörü Özelinde Bir Değerlendirme
Authors: KOTAN TÜRKDEN Duygu , KUŞAY Yeliz
Published: April 2022

Kurumların sosyal, ekonomik ve çevresel yönetim anlayışları var olan değerleri geleceğe taşıma ihtiyacını gerektirmektedir. Bu gereksinimi sürdürülebilir kılacak en önemli etkenlerden biri de paydaş ilişkileri ya da iletişimsel anlamda hedef kitle iletişimidir. Son yıllarda ise kurumların sosyal sorumluluk anlayışı gereği yürüttükleri iletişim stratejileri, değişen toplumsal yapı, kaynakların sınırlılığı, çevresel problemler, toplumsal eşitsizlik gibi konuların daha sık tartışılmasıyla birlikte birçok kurumu yalnızca bir alan seçip bu alanda toplumu bilinçlendirme, herhangi bir toplumsal konuya dikkate çekme, farkındalık yaratma odağında tasarlanan kurumsal sosyal sorumluluk anlayışının ötesinde kurumların kendi iş süreçlerinden başlayarak yeniden yapılanmasını gerekli kılmaktadır. Bu kapsamda sürdürülebilirlik anlayışı da birbirine entegre bir yapıyı iletişim sürecine aktararak bütünselliği sağlamakta ve kurumları geleceğe taşımaya çalışmaktadır.Bu çalışmada Türkiye’deki bankacılık sektörünün Sürdürülebilirlik raporlarında yer alan “Sürdürülebilirlik İlkelerini” hedef kitle iletişiminde nasıl kullandığının incelenmesi amaçlanmaktadır. Sürdürülebilir halkla ilişkiler anlayışında paydaş katılımı ve desteği açısından sosyal medya kullanımı giderek önem kazanmaktadır. Hootsuite ve We Are Social 2021 Dijital Türkiye Raporuna göre 2021 yılında Türkiye’de en çok kullanılan sosyal medya platformu YouTube olarak karşımıza çıkmaktadır. Buradan hareketle çalışmada Küresel Raporlama Girişimi (Global Reporting Initiative-GRI) İlkeleri’ne göre sürdürülebilirlik raporunu yayınlayan ilk Türk mevduat bankası olan Akbank’ın 2021 yılı YouTube içerikleri, dokümantasyon tarama yöntemiyle incelenerek bir vaka çalışması yapılmıştır. Araştırma sonucunda bankanın YouTube içeriklerinde sürdürülebilirlik raporlarında yer alan ilkelere yönelik projelere yer verdiği görülmekle birlikte, hesabın yorumlara kapalı olması paydaş katılımını sınırlayıcı bir unsur olarak yorumlanmıştır.

Authors: CANAZ Funda , YILMAZ Evrim , ARIK Deniz , ÖZTAŞ Erkin , ŞAHİN Adnan
Published: April 2022

Giriş ve Amaç: İnflamatuvar fibroid polip gastrointestinal kanalda nadir gelişen benign bir lezyondur. Çalışmamızda 10 yılda hastanemizde gastrointestinal kanalda bildirilen inflamatuvar fibroid polip olgularının klinik, morfolojik ve immünohistokimyasal özelliklerini tartışmayı amaçladık. Gereç ve Yöntem: Bu çalışmada 22 inflamatuvar fibroid polip olgusu klinik, morfolojik ve immünohistokimyasal özellikleri ile sunulmuştur. Olguların yaşı, cinsiyeti, inflamatuvar fibroid polip için uygulanan tedavi şekli, tümörün çapı, lokalizasyonu ve morfolojik özellikleri ile immünohistokimyasal boya sonuçları kaydedilmiştir. Bulgular: Olguların 19’u (%86.4) kadın, 3’ü (%13.6) erkekti. Olguların yaşları 44 - 74 arasında değişmekte olup, ortalama yaş 60 ± 6.9 yıldı. Lezyon boyutları 0.7 - 5.5 cm arasında değişmekte olup, ortalama 1.9 cm idi. İnflamatuvar fibroid polip en sık mide (n: 13) lokalizasyonunda idi, bunu ince barsak (n: 8) ve kolon (n: 1) takip etmekteydi. Olguların tümünde tipik morfolojik özellikler olan ince ve kalın duvarlı damarların eşlik ettiği iğsi hücre proliferasyonu ve eozinofil infiltrasyonu izlendi. Vimentin tüm olgularda diffüz pozitif bulundu. 21 olguda CD34, 3 olguda düz kas aktin pozitifti. 4 olguda östrojen reseptörü fokal boyanma, 1 olguda progesteron reseptörü fokal boyanma gösterdi. Olguların tümünde S100, desmin, CD117, androjen reseptör negatifti. Sonuç: İnflamatuvar fibroid polip submukozada lokalize olup sıklıkla mukozaya ilerleyebilmektedir. Regüler vasküler patern, iğsi hücre proliferasyonu, eozinofilik infiltrasyon tipik morfolojik bulgularıdır. Gastrointestinal kanalda iğsi hücreli tümörlerin ayırıcı tanısında inflamatuvar fibroid polip yer almalıdır. Klasik mikroskopik görünümü dışında morfolojik bulgular gözlendiğinde ayırıcı tanının zor olabileceği akılda tutulmalı ve tanının immünohistokimyasal belirteçlerle desteklenmesi gerektiği unutulmamalıdır.

Published: April 2022

Background and Objectives: Health care workers (HCWs) are a high-risk group for acquiring and transmitting severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection. Aim of the study was the evaluation of sero-prevalence of SARS-CoV-2 in a random sample of HCWs at a large acute care hospital in Iran.
Materials and Methods: We collected blood samples of 180 medical staffs from September 22, 2020 to January 26, 2021. The enzyme linked immunosorbent assays (ELISA) tests were used for evaluation of the presence of IgG antibodies. Participants completed a self-report questionnaire, comprising demographics, occupational, the work area, and personal protection data.
Results: Of the 180 HCWs who participated in this study, 44 (24.4%) were seropositive for anti-SARS-CoV-2 IgG. The percentage of IgG positivity was higher in males than females (P<0.05). Also, there was statistically significant difference between presence of the antibodies and the occupation, location, and infecting family members with Covid -1 (P<0.05). Other factors did not associate significantly to antibody presence against SARS-CoV-2 (P>0.05).
Conclusion: According to this point that the number of COVID-19 cases is still growing rapidly among HCWs. So, the epi- demiological estimate of SARS-CoV-2 infection remains a major challenge that is needed to prevent the spread of infection in the hospitals.

Published: April 2022

Background and Objectives: Prostatitis affects about 16% of men in their lifetime and sometimes leading to prostate cancer. Bacterial infections are the most common causes of prostatitis. Diagnosis of the causative agents of bacterial prostate infections plays an essential role in timely treating and preventing secondary complications. This study isolat- ed bacterial infectious agents in patients’ surgical prostate and evaluated them by routine and molecular microbiological methods.
Materials and Methods: In this cross-sectional study, 72 prostate biopsy specimens were collected from the Orology De- partmen of hospitals of Qazvin University of Medical Sciences. All samples were cultured in aerobic and anaerobic condi- tions. Antibiotic susceptibility test by Kirby-Bauer standard method was performed for all isolated bacteria. In addition, all isolated bacteria were identified using 16S rDNA PCR and sanger sequencing methods. Also, TaqMan real-time PCR was applied to detect Ureaplasm aurealyticum, Mycoplasma hominins, and Mycoplasma genitalium.
Results: In conventional culture method, out of 18 positive samples, 15 samples (83.3%) were Gram-negative bacteria and 3 samples (16.6%) were Gram-positive bacteria, containing Escherichia coli (55.5%), Klebsiella pneumoniae (11.1%), En- terobacter cloacae (5.5%), Pseudomonas aeruginosa (11.1%), Staphylococcus aureus (11.1%), and Enterococcus faecalis (5.5%). The results of molecular identification methods were the same as conventional culture results. Also, four patients were Ureaplasm aurealyticum, and three patients were positive for Mycoplasma hominis.
Conclusion: Most bacteria isolated from prostate specimens belonged to the Enterobacteriaceae family, especially Esch- erichia coli, Klebsiella pneumoniae, Enterobacter cloacae. Staphylococcus aureus and Enterococcus faecalis were cocci isolated in the specimens too. Also, Ureaplasma urealyticum, and Mycoplasma hominis were identified in prostatitis.

Published: April 2022

Background and Objectives: Acinetobacter baumannii has emerged as a major organism accounting for hospital acquired infections particularly in intensive care units. Due to production of different kinds of beta lactamases these bacteria have developed drug resistance rendering the treatment of such infections very difficult and expensive. Rapid identification of A. baumannii producing such beta-lactamases is the need of the hour in reducing morbidity and mortality associated with A. baumannii infections.
Materials and Methods: A. baumannii was isolated from clinical samples like endotracheal aspirates, sputum, urine, exu- dates using standard culture techniques. Identification and drug sensitivity was done using Vitek 2 system. All the isolates were subjected to detection of ESBLs using phenotypic confirmatory test, plasmid mediated AmpC beta- lactamase by AmpC disc test, Carbapenemase production by CarbAcineto NP Test and Modified hodge method.
Results: 149 A. baumannii isolates were analysed for antimicrobial susceptibility and various beta-lactamase production. Results were evaluated for statistical significance using Chi-Square and P value. 81.8% of isolates were from male patients with majority of them above 50 years of age. 88.5% of samples were from ventilator associated pneumonia patients. 83.8% of isolates were sensitive to tigecycline. Only 10% to 12% of isolates were sensitive to carbapenems. 23.4% of isolates were ESBL producers and 46.9% of them were AmpC producers. Modified Hodge test method identified 63.7% of A. baumannii as carbapenemase producers where as CarbAcineto NP test identified 63% and exibiting 94.74% sensitivity, 93.22% specificity when compared to Modified Hodge test.
Conclusion: Multidrug resistant Acinetobacter spp. is on the rise. Present study showed that high percentage of drug resis- tance in A. baumannii could be due to production of ESBLs, AmpC and carbapenemases. Among all beta lactamases car- bapenemase producers are more and quickly raising in A. baumannii. Rapid, cost effective assay which can be adopted in all clinical laboratories is critical to prevent their further transmission particularly in hospital environment.

Published: April 2022

Background and Objectives: Bacteriocins are antimicrobial peptides produced by many genera of bacteria especially Lac- tobacillus spp. against many pathogens, adapt bacterial composition in the gut and inhibit dysbiosis that can lead to inflam- mation disorders like inflammatory bowel disease (IBD). The aim of this study was to compare the prevalence of bacteriocin genes in health, IBD disease and recovery conditions.
Materials and Methods: In this survey 115 Lactobacillus spp. from 58 fecal samples of three different groups were evaluat- ed. Comparison of the presence of bacteriocin genes in different groups were assayed by purified samples and PCR method, followed by statistical analysis to identify the effect of inflammation in the proportion of Lactobacillus spp. and presence of their bacteriocin genomes.
Results: Of 115 Lactobacillus spp. 60% of samples had positive bacteriocin-encoding genes which included: gassericin-A 29.56%, acidocin 15.65%, plantaricin-NC8 18.26%, plantaricin-S 13.04%, lactacin-F 9.5%, sakacin-P 6.08% and gasseri- cin-T 6.08%. Results indicated that the percentage of positive bacteriocin genes were much more in healthy volunteer and IBD-recovered in comparison to IBD-patients which showed the effect of inflammation in the presence of bacteriocin genes.
Conclusion: The results obtained in this study demonstrated that the presence of bacteriocin genes can be related to health and disease states and inflammatory disease affected the prevalence of bacteriocin-encoding genes. This approach can help to identify bacterial functions that can be targeted in future concepts of IBD therapy.

Influence of Spacecraft Surface Spectral Radiation Characteristics on the Accuracy of Thermal Load Simulations in Infrared Simulators
Authors: Kolesnikov A.V. , Paleshkin A.V. , Pronina P.F. , Shemetova E.V.
Published: April 2022

Relying on the data on the spectral absorptivity of materials and coatings used in space engineering, we estimated the level of possible errors in simulating the given external thermal loads on the spacecraft surface in infrared simulators with emitters of grey radiation characteristics. We used an assumption, which is introduced in the known methods for determining the optimal mode of the operation, that the outer spacecraft surface elements' spectral absorptivity does not depend on the wavelength of the incident radiation in the spectral bandwidth of the simulator. Findings of the research show that errors depend on the emitter temperature, especially for those coatings having spectral characteristics of radiation in the near infrared region of spectrum which cardinally differ from these characteristics in the middle and far regions of spectrum. For some coatings, the errors are unacceptably large. We arrived at a conclusion that it is necessary to adjust the known techniques to solve the problem of choosing the operating modes of infrared simulators. The technique is based on the iteration process of searching for a solution of the problem including repeated determination of radiation intensity vector of the simulator modules by minimization of the target function ψ with simultaneous specification, at each iteration, of coefficient values characterizing the absorptivity of the spacecraft outer surface elements with respect to radiation arriving from the simulator modules

Published: April 2022

Identification and verification of a new version of mathematical model for universal modeling method for calculation of centrifugal compressors gas dynamic characteristics are carried out. To identify the loss model, the results of 70 tests of 20SE family model stages at LPI-SPbPU Compressor Engineering Problem Laboratory were used. A total of 420 efficiency values were compared. At the first stage, identification was carried out only for stages without a vane diffuser; the average error of efficiency calculation was 0.513 %, and, on the whole, for the characteristic is 1 %. When identifying vane diffuser stages, the search objects were coefficients influencing losses in the vane diffuser only, the average error of efficiency calculation was 0.525 %, for the whole characteristic is 1.12 %. To verify the empirical coefficients affecting losses in the axial separation impeller, test results of TKR-175E and TKR-140E compressors for turbocharger units were used. In the IDENT database we gave characteristics of TKR-140E compressor at conditional Mach numbers 0.437, 0.5836, 0.728, 0.8739; average error of efficiency calculation was 0.889 %, for the whole characteristic is 1.55 %. To verify the mathematical model, the results of the tests of Clark (USA) low-flow model stages were used. Ten tests of low-flow stages were considered; the average error of efficiency calculation was 1.08 %, for the whole characteristic is 1.31 %
​Techniques for Detection and Diagnosis of Plant Viruses: A Review
Authors: Sharma Jyoti , Lager Priya , Kumar Yogesh
Published: April 2022

Plant viruses are famed for serious economic losses to most of the agricultural and horticultural crops all around the world. The losses caused by plant viruses are estimated to be several billion bucks per year and are therefore a major threat to global crop production and food security. Traditional diagnostic methods based on biological and physical properties of virus such as appearance of symptoms, bioassay on indicator plants, vector borne and virus particle morphology by electron microscopy are cumbersome, time-consuming and expensive. Recognition of disease based on the symptoms indicated by virus affected plants, can invariably be the first process in several cases, however it’s confusing additionally as a result of the symptoms are changeable and depends on several factors like abiotic conditions. There are several sensitive and effective diagnostic methods developed during the last four decades based on virus protein e.g., immunosorbent electron microscopy (ISEM), enzyme-linked immunosorbent assay (ELISA) and nucleic acid e.g., nucleic acid hybridization, isothermal and thermostable PCRs, for plant virus detection, each having its own advantage and disadvantage. This review provides an update on the progress made on the techniques that are useful for early, sensitive, accurate and reliable detection and diagnosis of plant viruses.

Published: April 2022

El propósito del presente estudio fue adaptar y validar la Escala de Tolerancia a la Frustración (Oliva et al., 2011) para su uso en población adolescente peruana. El muestreo fue intencional y se evaluó a 436 adolescentes quechuahablantes de Cusco y Apurímac, entre los 12 y 17 años de edad de ambos sexos. Se analizó la estructura factorial de la escala y su confiabilidad. Para esto, se aplicó el Análisis Factorial Exploratorio (AFE) y el Análisis Factorial Confirmatorio (AFC), donde se dividió la muestra estadística de manera aleatoria en 206 y 230 participantes respectivamente. Los resultados evidencian que el AFE revela la unidimensionalidad de la escala con autovalores mayores a los generados por el azar y que explica el 44.5% de la varianza total. Asimismo, las cargas factoriales fueron mayores a 0.40 y el AFC corroboró esta estructura. El modelo evidenció satisfactorios y mejores índices de ajuste (CFI = 1.000; RMSEA = .000; SRMR = .049). El coeficiente de consistencia interna fue adecuado (ω = .67). Se concluye que, la traducción al quechua de la escala cuenta con evidencias preliminares para ser considerada una medida precisa, válida e invariante para evaluar la tolerancia a la frustración en adolescentes quechuahablantes peruanos.

Authors:   , Camacho Molina Diana Ursula
Published: April 2022

El objetivo del presente estudio fue analizar las propiedades psicométricas de la Escala de Síndrome Premenstrual (ESPM) en una muestra de 461 estudiantes universitarias de pregrado de cuatro universidades privadas de Lima Metropolitana. El rango de edades de la muestra fue de entre los 16 a 27 años (M = 19.70, DE = 1.84). Los instrumentos aplicados fueron la ESPM, la Escala de Ansiedad de Zung (EAZ) y la Escala de Depresión de Zung (EDZ). Como evidencia de validez basada en la estructura interna, se realizó un análisis factorial exploratorio (AFE, n = 230) teniendo como resultado una estructura de nueve factores relacionados que explicaron el 56.35% de la varianza total considerando 41 de los 44 ítems originales. Luego se realizó un análisis factorial confirmatorio (AFC, n = 231) para evaluar el ajuste del modelo obtenido en el AFE, en el cual se obtuvieron adecuados índices de bondad de ajuste (χ2 = 1168.49; χ2/gl = 1.79; CFI = .90; RMSEA = .06; SRMR = .06), con la especificación de tres pares de errores correlacionados y la eliminación de dos ítems adicionales, resultando una estructura factorial final de 39 ítems. Los coeficientes de confiabilidad omega oscilaron entre .72 y .90. Como evidencia de validez convergente, se encontraron relaciones positivas y estadísticamente significativas entre las nueve dimensiones de la ESPM y las medidas de ansiedad y depresión. Se concluye que la ESPM y sus puntuaciones derivadas son una medida válida y fiable para evaluar el síndrome premenstrual en la población evaluada.

We are how much we Eat: Nutrient-Specific Versus Calorie-Based Adult-Equivalent Scales
Authors: Ali Mohammad , Villa Kira M
Published: April 2022

The accurate conversion of household-level food availability into individual-level nutrient availability depends on which adult-equivalent scale is employed. The purpose of this paper is to come up with a set of adult-equivalent scales based on the specific daily intake requirement for macro- and micronutrients. Using t-tests on household-level data from Nepal, we also attempt to find whether on average there are differences between the individual-level nutrient availability estimates when they are calculated through nutrient-specific versus calorie-based, per capita, or Organization for Economic Cooperation and Development (OECD) adult-equivalent scales. The results suggest that on average there are significant differences between the individual-level nutrient availability estimates depending on which adult-equivalent scale is used. Finally, we find that nutrient-income elasticities calculated through different adult-equivalent scales are statistically different from each other. Thus, the nutrient-specific adult-equivalent scales derived in this paper have the potential to reduce measurement error in future studies.

Published: April 2022

Religious, economic, political, social, and cultural factors influence professional autonomy in nursing, and differ from country to country. The aim of this study was to explain barriers and facilitators of professional autonomy in the experience of clinical nurses. This qualitative study was conducted on 19 clinical nurses and nursing managers selected based on purposive sampling from January 2018 to December 2019. Data were collected through semi-structured interviews, which continued until data saturation was reached. Conventional content analysis based on the Graneheim and Lundman approach was used to analyse the data. Data were categorised into 34 subcategories, 8 main categories, and two main themes, which were titled as facilitators of professional autonomy (professional, organisational, and individual factors, and effective communication) and barriers to professional autonomy (professional, organisational, and personal barriers, and inappropriate communications). The results discussed a set of facilitators and barriers faced by Iranian nurses in clinical settings. Professional organisations can play a key role by enhancing professional autonomy facilitators and increasing professional support for nurses. Another finding was the importance of training nursing staff to be competent and autonomous, beginning right from the college years.

Published: April 2022

This study aims to determine the impact of the spin-off on the level of efficiency of Sharia insurance in Indonesia by using the Data Envelopment Analysis (DEA) method. This study uses data from companies that have undergone a spin-off, namely Jasindo Syariah and Askrida Syariah, both before the spin-off and after the spin-off. Input data are assets, operating expenses, while output data are profit and operating income for a period of 5 years each. From the results of data processing, it shows that the two companies experienced a decrease in their level of efficiency towards profits after spin-off, but the level of efficiency on income, for Sharia Jasindo are relatively stable, while the Sharia Askrida has decreased.
Overcoming the Economic Crisis due to a Pandemic through Islamic Finance
Authors: Ashraf Muhammad Ammar
Published: April 2022

The Covid-19 disaster is an exogenously induced downturn that is expected to leave 2021 global GDP approximately 5 percentage points lower than in January 2020 pre-Covid-19 estimates. The negative impact on low-income households is especially severe, jeopardizing the world's significant progress in reducing extreme poverty since the 1990s. To react to frequent crises and catastrophe global economic stagnation, a new paradigm is required. Institutionalized risk-sharing can assist the global economy in resiliently absorbing shocks and stimulating stagnant demand. Islamic finance principles assist the economy in avoiding endogenously generated crises, such as the Global Financial Crisis, and provide a strong safety net against exogenously induced cycles, such as the Covid-19 crisis. In practice, this necessitates a diverse set of well-functioning institutions to translate these principles into real-world impact. As it currently stands, the Islamic financial industry’s many essential components of this spectrum are still missing. The crisis should be viewed as an opportunity to fill gaps and diversify the industry. Given the fact that the Covid-19 crisis is exogenously induced, the impact on Islamic banks is expected to be comparable to that on conventional banks. The similarity of their business model, sharia-compliant equities, on the other hand, outperformed their conventional counterparts. The ineffectiveness of non-profit organizations, like awqaf and zakat, reduced the role of the safety net in curbing the repercussions of the crisis. The Covid-19 pandemic poses liquidity, resilience, and capital challenges for the Islamic banking sector.

Published: April 2022

This study discusses the Analysis of the Potential of the Halal Tourism Industry in the Special Region of Yogyakarta. As a student city and tourism city, Yogyakarta has various tourism potentials that developed to the fullest, such as based on the religious background of its visitors, especially for Muslims. This research aims to find out the possibility of the halal tourism industry in the Special Region of Yogyakarta, explain the industry's concept, and find out its development strategy. The urgency of this research is to map and develop the potential of halal tourism in the Special Region of Yogyakarta and to design the design of the halal tourism industry based on local wisdom values that do not substantively conflict with Islamic law. In addition, to provide a new paradigm in the tourism industry system that still prioritizes comfort based on the values of belief held by tourists. This research is field research in various Yogyakarta tourism areas with a normative - sociological - phenomenological approach. Primary and secondary data sources are obtained through field studies and through document studies related to research using content analysis of research instruments are the researchers themselves. The study results found that there were several religious tourism objects and various other tourist objects that had indirectly applied some of the principles of the sharia tourism industry. The existence of several sharia hotels supports this to increase the attractiveness of Muslim tourists to visit DIY. To further increase the existing potential, it is necessary to have a local government regulation that explicitly regulates the existence of the sharia tourism industry, as has been done by the local government of Lombok, West Nusa Tenggara.
