Published: July 2020

Rangkaian proses rumit yang menghasilkan nilai filosofi tinggi pada batik mulai ditinggalkan oleh masyarakat pembuatnya yakni para perajin batik. Fenomena menurunnya minat generasi muda untuk melanjutkan pembuatan batik tradisi di sentra-sentra batik merupakan masalah yang harus dipecahkan dari berbagai latar belakang, di antaranya secara sosial dan budaya. Solusi dan alternatif pemecahan masalah dengan menggunakan konsep kearifan lokal perlahan diterapkan kembali oleh para perajin batik di Girilayu. Tujuan penelitian ini antara lain: 1) mengetahui penyebab menurunnya pembuatan dan penggunaan batik tradisi dari segi sosial serta budaya, 2) mengetahui peran kearifan lokal masyarakat Jawa dari aspek efektifitasnya untuk melestarikan batik tradisi, dan 3) menguraikan cara penerapan kearifan lokal dalam melestarikan batik tradisi di Girilayu. Metode penelitian yang dipergunakan yakni wawancara mendalam pada para perajin batik di Girilayu sebagai pelaku, tokoh, dan pakar batik; serta studi pustaka referensif. Pendekatan antropologis dipergunakan untuk mengumpulkan dan menganalisis data berdasarkan realitas di masyarakat. Penelitian ini menemukan bahwa peran kearifan lokal masyarakat Jawa dalam melestarikan batik tradisi di Girilayu dapat berjalan efektif melalui dukungan pendidikan keluarga dan sekolah secara intensif.
Robots and the Gender Pay Gap in Europe
Authors: Aksoy Cevat Giray , Ozcan Berkay , Philipp Julia
Published: July 2020

Could robotization make the gender pay gap worse? We provide the first large-scale evidence on the impact of industrial robots on the gender pay gap using data from 20 European countries. We show that robot adoption increases both male and female earnings but also increases the gender pay gap. Using an instrumental variable strategy, we find that a ten percent increase in robotization leads to a 1.8 percent increase in the gender pay gap. These results are mainly driven by countries with high levels of gender inequality and outsourcing destination countries. We then explore the mechanisms behind this effect and find that our results can be explained by the fact that men at medium- and high-skill occupations disproportionately benefit from robotization (through a productivity effect). We rule out the possibility that our results are driven by mechanical changes in the gender composition of the workforce nor by inflows or outflows from the manufacturing sector.

Constructing Pathways to Responsible Manhood
Authors: Torres Mellie , Carrión Alejandro E. , Martínez Roberto
Published: July 2020

Recent studies have focused on challenging deficit narratives and discourses perpetuating the criminalization of Latino men and boys. But even with this emerging literature, mainstream counter-narratives of young Latino boys and their attitudes towards manhood and masculinity stand in stark contrast to the dangerous and animalistic portrayals of Latino boys and men in the media and society. Utilizing a mixed-methods approach, the authors draw on the notion of counter-storytelling to explore how Latino boys try to reframe masculinity, manhood, and what they label as ‘responsible manhood.’ Counter-storytelling and narratives provide a platform from which to challenge the discourse, narratives, and imaginaries guiding the conceptualization of machismo. In their counter-narratives, Latino boys critiqued how they are raced, gendered, and Othered in derogatory ways.

Authors: Barker D.J. , Lancashire J.A. , Meurk C.
Published: July 2020

ocksfoot (Dactylis glomerata L.) is the second most commonly sown grass after ryegrass (Lolium spp.) in New Zealand. Some characteristics restricting its performance in pastures have been improved in a new variety 'Grasslands Wana' cocksfoot, released in 1980. A series of trials at Taupo, Woodville, Central Wairarapa and Eastern Southland showed that under sheep grazing Wana can be established as the dominant component of the sward. It was concluded that Wana has potential as both a dry and moist hill country pasture grass and particularly in dry environments may have advantages over the species currently present.

Biodegradation of tannery effluent and its impact on seed germination of
Oryza sativa
Authors: Sivakumar Jenny , Perumal Malliga
Published: July 2020

Environmental
pollution, especially of water bodies, is one of the major problems and it is
increased day by day. The contamination of environment with various toxic
metals is a serious threat for ecosystem and human health. Industrial effluents
may contain toxic metals, harmful volatile compounds and several organic and
inorganic compounds such as chromium, cadmium, mercury, arsenic and lead which
are directly or indirectly discharged into the environment without adequate
treatment. However, tannery industries are the major source of chromium
contamination into the environment. Tanneries are typically characterized as
pollution intensive industrial complexes which generate widely varying,
high-strength wastewaters. The discharge of these toxic effluents has been a
major loss from the ecological, social and economic perspective. There are many
conventional physiochemical methods available for the removal of heavy metals
from the tannery effluents that are highly expensive and require skilled
techniques. However, microbial reduction of toxic chromium to non-toxic
chromium by chromium resistance microorganism is the most pragmatic approach
that offers an economical as well as eco-friendly process. Hence, this study
examines the biodegradation of tannery effluent and its impacts on the
germination of Oryza sativa seeds.
Preventative Effect of Mebendazole against Malignancies in Neurofibromatosis 1
Authors: Staedtke Verena , Gray-Bethke Tyler , Riggins Gregory J. , Bai Ren-Yuan
Published: July 2020

Patients with RASopathy Neurofibromatosis 1 (NF1) are at a markedly increased risk of the development of benign and malignant tumors. Malignant tumors are often recalcitrant to treatments and associated with poor survival; however, no chemopreventative strategies currently exist. We thus evaluated the effect of mebendazole, alone or in combination with cyclooxygenase-2 (COX-2) inhibitors, on the prevention of NF1-related malignancies in a cis Nf1+/−;Tp53+/− (NPcis) mouse model of NF1. Our in vitro findings showed that mebendazole (MBZ) inhibits the growth of NF1-related malignant peripheral nerve sheath tumors (MPNSTs) through a reduction in activated guanosine triphosphate (GTP)-bound Ras. The daily MBZ treatment of NPcis mice dosed at 195 mg/kg daily, initiated 60 days after birth, substantially delayed the formation of solid malignancies and increased median survival (p < 0.0001). Compared to placebo-treated mice, phosphorylated extracellular signal-regulated kinase (pERK) levels were decreased in the malignancies of MBZ-treated mice. The combination of MBZ with COX-2 inhibitor celecoxib (CXB) further enhanced the chemopreventative effect in female mice beyond each drug alone. These findings demonstrate the feasibility of a prevention strategy for malignancy development in high-risk NF1 individuals.
USE OF IRAQ CONCRETE SCRAP AS FILLER AND AGGREGATE OF HEAVYWEIGHT AND LIGHTWEIGHT CONCRETE
Authors: Ahmed A. , Fedyuk R.S. , Liseycev Yu. , Timohin R. , Murali G.
Published: July 2020

the relevance of the paper is due to the search for alternative sources of raw materials for the construction industry, associated with the disposal of man-made waste. The novelty of the article is to identify the scien-tific laws of the influence of demolition waste on buildings and structures on the formation of the micro-structure of lightweight and heavyweight concrete. Concrete waste was prepared as both fillers of cement materials and fine aggregates, based on which concrete with high mechanical properties was created. The mix design was carried out from the point of view of geomimetics, in particular, taking into account the law of affinity of structures. The strength characteristics of concrete mixtures were investigated in accordance with EN 12390-3. In addition, the microstructural, morphological and thermal properties of the raw materials and concrete were determined during 28-day curing. For the first time, the dense microstructure of the com-posite was ensured, both with Portland cement products and with hydration, and, in part, with hydration products of previously unreacted clinker, whose minerals are present in concrete waste and are activated when they are crushed. The use of demolition waste of buildings and structures as a filler of cementing ma-terial when replacing Portland cement up to 20% allows to obtain better compressive strength of both heav-yweight and lightweight concrete.

Published: July 2020

Se colectó germoplasma de cucurbitáceas en el norte del Perú, en las regiones de Tumbes, Piura, Lambayeque y Cajamarca, para un total de 8 géneros, 14 especies y 202 accesiones, sobre todo de la región Lambayeque que tuvo el mayor número de accesiones. Este material genético se conserva desde 1988 hasta la actualidad a 10 °C de temperatura, con una tasa de viabilidad de las semillas de 90 %. Se evaluaron las características morfológicas de frutos y semillas de las especies Cucurbita ficifolia, C. moschata, C. maxima y Cucurbita sp., una variedad local conocida como “loche”, y Lagenaria siceraria. Las accesiones de Cucurbita fueron muy variables en forma, tamaño y color de fruto, y forma y tamaño de semilla. Las accesiones de Lagenaria destacaron por la amplia variabilidad en forma y tamaño del fruto, en las que se reconocieron los tipos “calabazos”, “lapas”, “mates” y “checos”, con numerosas formas intermedias. Se discute la posibilidad de que los genotipos “chuyán” y “loche”, clasificados tradicionalmente como C. moschata, pudieran constituir subespecies. Se concluye que la costa norte del Perú es un centro de alta diversidad morfológica de C. moschata y L. siceraria, y la región altoandina de Cajamarca y Piura de C. ficifolia.

Published: July 2020

En Yucatán existe una gran riqueza de conocimiento sobre el uso de las plantas medicinales, que se encuentra en riesgo debido a los actuales procesos de deterioro ambiental y cultural. En este trabajo se da a conocer el establecimiento de jardines comunitarios como una estrategia para salvaguardar el conocimiento que el pueblo maya posee acerca de la flora medicinal y conservar los recursos fitogenéticos de uso medicinal. Se establecieron cuatro jardines medicinales, mediante el método de investigación participativa. Los jardines resguardan el germoplasma de 206 especies, pertenecientes a 170 géneros y 66 familias botánicas; de éstas 160 son especies nativas, de las cuales 11 son endémicas de la Península de Yucatán y 46 son exóticas. Estas especies medicinales se emplean para tratar 301 padecimientos. Las categorías con mayor número de usos son problemas dermatológicos (68), gastrointestinales (59) y reproductivos (33). Estas categorías de uso también incluyeron el mayor número de especies: 82 para problemas dermatológicos, 72 para gastrointestinales, y 35 para los reproductivos y síndromes de filiación cultural. Las especies con mayor valor de uso fueron Aloe vera (L.) Burm. f. (5.5), Ocimum campechianum Mill. (4.75), Tithonia diversifolia (Hemsl.) A. Gray (4.75), Ruta chalepensis L. (4.5), Tradescantia spathacea Sw. (3.5), Parthenium hysterophorus L. (3.25), Chromolaena odorata (L.) R. M. King & H. Rob. (3.0) y Cissampelos pareira L. (3.0). Las especies con mayor consistencia de uso fueron Tithonia diversifolia para el reumatismo (100 %), y Diphysa carthagenensis Jacq. para el mal de ojo (100 %); además se encontraron 12 especies con una consistencia de uso de 75 %. A largo plazo se espera que siguiendo esta estrategia se pueda consolidar una red de jardines medicinales que contribuya a salvaguardar la flora medicinal y el conocimiento asociado al uso de las plantas en esta región del país.

O sedentarismo atualmente aparece como fator de risco para mortalidade, e a atividade física regular é reconhecida pelos seus efeitos salutares nos seus praticantes. É possível relacioná-la, além do fortalecimento muscular proveniente desta prática, a alterações positivas para combater ou prevenir o aparecimento de diversas patologias. No escopo do fisioterapeuta existem várias técnicas que podem ser utilizadas para o fortalecimento muscular. O Exercício Terapêutico (ET) é considerado um elemento central na maioria dos planos de assistência da fisioterapia, complementado por outras intervenções, com a finalidade de aprimorar a função e reduzir incapacidades, já a eletroestimulação é utilizada na reeducação muscular, redução de espasmos, retardo na hipotrofia e fortalecimento de músculos. Uma das formas de fortalecimento do músculo reto abdominal são os chamados exercícios abdominais que apresentam diversas formas de execução. Outra maneira de aumentar a força muscular desta região é por meio da Corrente Russa (CR) que deflagra por meio da estimulação elétrica uma contração muscular. No presente estudo a metodologia utilizada consistiu na avaliação da força inicial através do Eletromiógrafo de Superfície (EMS) e fotodocumentação, aplicação dos protocolos, cada um composto por vinte sessões sendo um de ET e outro de ET associado a CR e por fim a reavaliação com o EMS, fotodocumentação e questionário de satisfação pessoal. O objetivo geral deste estudo visou verificar os efeitos da corrente russa e do exercício terapêutico no músculo reto abdominal em mulheres sedentárias. A amostra foi composta por oito participantes, sendo estas divididas em dois grupos (Grupo A e B), sendo cinco no primeiro grupo e três no segundo. O resultado final da EMS constatou que o protocolo ET exclusivo ou associado à CR altera a média a média da curva eletromiográfica RMS, porém não houve diferença de efeito entre os protocolos. Desta forma, conclui-se que ambos os protocolos são eficazes para o fortalecimento muscular, sendo de extrema importância na prática fisioterapêutica.

A obesidade é uma patologia, que assola uma grande parte da população no Brasil. Essa assertiva está embasada em dados recentes fornecidos pelo Instituto Brasileiro de Geografia e Estatística (IBGE). A escola, núcleo de concentração do futuro da nação se notabiliza como local com grande prevalência dessa patologia. Os professores de educação física podem exercer um importante papel na reversão desse quadro. Atualmente, as aulas de educação física vêm sofrendo ajustes no que tange a sua periodicidade. A literatura relata que em algumas escolas as aulas acontecem com uma frequência semanal de apenas uma vez. Muitos profissionais ainda com a visão tecnicista reproduzem gestos desportivos nas aulas como conteúdo, gerando um possível absenteísmo. Assim sendo, o presente estudo tenta responder algumas perguntas dentre elas, qual o atual cenário da obesidade entre escolares no Brasil? O absenteísmo dos alunos nas aulas de educação física escolar pode ser considerado como um dos possíveis motivos para o desenvolvimento dessa patologia?

Published: July 2020

Although large and sparse linear systems can be solved using iterative methods, its number of iterations is relatively large. In this case, we need to modify the existing methods in order to get approximate solutions in a small number of iterations. In this paper, the modified method called second-refinement of Gauss-Seidel method for solving linear system of equations is proposed. The main aim of this study was to minimize the number of iterations, spectral radius and to increase rate of convergence. The method can also be used to solve differential equations where the problem is transformed to system of linear equations with coefficient matrices that are strictly diagonally dominant matrices, symmetric positive definite matrices or M-matrices by using finite difference method. As we have seen in theorem 1and we assured that, if A is strictly diagonally dominant matrix, then the modified method converges to the exact solution. Similarly, in theorem 2 and 3 we proved that, if the coefficient matrices are symmetric positive definite or M-matrices, then the modified method converges. And moreover in theorem 4 we observed that, the convergence of second-refinement of Gauss-Seidel method is faster than Gauss-Seidel and refinement of Gauss-Seidel methods. As indicated in the examples, we demonstrated the efficiency of second-refinement of Gauss-Seidel method better than Gauss-Seidel and refinement of Gauss-Seidel methods.

Published: July 2020

El test ECCO_Senior se diseñó para evaluar la comprensión de oraciones en adultos mayores. Es una prueba corta y de fácil aplicación, que se ha empleado en distintos estudios previos. En el estudio participaron 670 personas, de 50 a 85 años de edad, que cumplían criterios de inclusión relativos al estatus cognitivo general, el estado de ánimo y porcentaje mínimo de aciertos en el test. Además de los test de cribado (MEC y GDS-15) y un cuestionario socio-demográfico, se aplicó a todos los participantes el test ECCO_Senior con el que se pueden obtener distintos índices (generales y específicos). Además de comprobar si existen diferencias entre los grupos según la edad y el nivel educativo, se evaluaron las propiedades psicométricas del test, incluyendo evidencias de validez en las que se probó la bondad de ajuste de tres modelos estructurales que sirven para identificar los índices que explican un mayor porcentaje de la varianza del constructo (comprensión de oraciones). Se ofrecen normas interpretativas del test por edad y nivel de estudios en los Apéndices. Los resultados indican que el test permite evaluar la comprensión de oraciones con una fiabilidad adecuada y es sensible a las dificultades que puede experimentar un adulto al realizar esta tarea. Los tres modelos muestran un buen ajuste y permiten concluir que las oraciones no ajustadas al orden sintáctico canónico y los distractores léxicos (si se considera el tipo de ítem) serían los mejores indicadores en términos del porcentaje de la varianza del constructo que explican.

We implemented multiple nucleic acid amplification test platforms because of the limited availability of test kits for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) during the early stages of the pandemic. Interpretation of results generated by different platforms and prioritization for testing algorithms required cross-comparison.

Objective.—

To compare the analytical sensitivity of 3 commercial SARS-CoV-2 molecular assays, selected samples were studied in parallel with Cobas SARS-CoV-2 test, NxTAG CoV Extended Panel, and ID NOW COVID-19 assays.

Design.—

A total of 8043 SARS-CoV-2 tests performed from March 22 to April 19, 2020, were included in this study. For all 1794 positive specimens detected by the cobas SARS-CoV-2 assay, the cycle threshold (Ct) values were manually tracked and plotted to demonstrate the distribution of sample viral levels. Additionally, 50 and 63 low-positive specimens (Ct values >32) as well as 50 and 61 consecutive positive specimens by the cobas assay were tested with NxTAG and ID NOW, respectively, to estimate their relative sensitivities.

Results.—

The Ct values of cobas SARS-CoV-2–positive samples were evenly distributed throughout ranges of 13.32 to 39.50 (mean, 25.06) and 13.60 to 42.49 (mean, 26.45) for ORF1 and E gene targets, respectively. NxTAG reliably detected only specimens with E gene Ct values lower than 33, and is estimated to detect 89.4% of positive specimens detected by cobas assay. ID NOW had performance variation independent of Ct value and is estimated to detect 83.5% of cobas positives.

Conclusions.—

Clinical specimens exhibit a wide range of viral burden, with a significant portion at low levels. Analytical sensitivity of testing platforms is critical for reliable detection of SARS-CoV-2 and uniform care to patients.

Published: July 2020

Purpose

We investigated the correlation between visual acuity (VA) and individual retinal layer thickness in the foveal, parafoveal, and perifoveal regions of patients with an idiopathic epiretinal membrane (ERM).

Methods

One hundred and five subjects presenting with unilateral idiopathic ERM were included in this study. We segmented each patient’s optical coherence tomography (OCT) image into seven layers and calculated the mean layer thickness in the foveal, parafoveal, and perifoveal regions using the Iowa Reference Algorithm. In 105 patients with ERM, we detected correlations between their macular regions’ individual retinal layer thickness and their best corrected VA. Thirty-one of the 105 patients with ERM underwent vitrectomy and completed six months of follow-up. We then compared the 31 surgical patients’ preoperative and postoperative individual retinal layer thickness in each macular region. Additionally, the association between preoperative individual retinal layer thickness in each macular region and VA six months post-surgery in patients with ≥ two Snellen lines of visual improvement was determined.

Results

Multiple linear regression analysis showed that the inner nuclear layer (INL) thickness in the foveal, parafoveal, and perifoveal region were all associated with VA in the 105 patients (R2 = 0.344, P < 0.001; R2 = 0.427, P < 0.001; and R2 = 0.340, P < 0.001, respectively). Thirty-one surgical patients 6 months post-surgery showed significantly decreased thicknesses (P ≤ 0.012) of the foveal INL, inner plexiform layer (IPL), and outer nuclear layer (ONL); the parafoveal retina nerve fiber layer (RNFL), IPL, INL, and ONL; and the perifoveal RNFL, IPL, INL, ganglion cell layer (GCL), outer plexiform layer (OPL), and photoreceptor layer (PRL). We found a weak correlation between postoperative VA and preoperative foveal and perifoveal RNFL thickness (r = 0.404 and r = 0.359, respectively), and a moderate correlation between postoperative VA and preoperative foveal and parafoveal INL thickness (r = 0.529 and r = 0.583, respectively) in the 31 surgical patients (P ≤ 0.047). The preoperative INL thickness in the foveal, parafoveal, and perifoveal regions showed a moderate to strong correlation (r = 0.507, 0.644, and 0.548, respectively), with postoperative VA in patients with ≥ 2 lines of visual improvement (P ≤ 0.038).

Conclusion

We detected a correlation between retinal damage and VA in the parafoveal, perifoveal, and foveal regions. Our results suggest that INL thickness in all macular regions may be a prognostic factor for postoperative VA in ERM patients.

Authors: Tenywa J. S. , Odama E. , Amoding A. K.
Published: July 2020

Purpose: To evaluate the predictive capacity common procedures for soil P extraction and testing in laboratories in the region.

Materials and Methods: A pot study with treatments viz. soil phosphorus extraction methods (Bray I, Bray II and Mehlich 3), and six P application rates (0, 20, 40, 60, 80 and 100 kg P ha-1). Maize (Zea mays L.) variety Longe IV was the test crop. A Ferralsol from northwestern Uganda (West Nile) was used in this study.

Results and Conclusion: Mehlich 3 correlated most with plant P uptake by presenting the highest correlation coefficient with plant P content (r = 0.254) and a number of leaves per plant (r = 0.733). A strong positive correlation existed between Bray I and Mehlich 3 extractable P values (r = 0.975), suggesting lack of a marked difference between them; implying that either of the two procedures could be applied for soil P extraction in Ferralsols. However, Mehlich 3, being a multi-nutrient extractant, was recommended as the most suitable for P extraction for the Ferralsol used in this study.

Published: July 2020

Tooling materials used in the synthesizing of Mg alloys can introduce impurities, which can severely degrade the anticorrosion properties for the final Mg products. To address this issue, this work analyze the purity of molten Mg alloys AZ91D and AM50A in contact with three commonly used steels: 20#, H13, High‐CrNi (022Cr25Ni7Mo4N) for different durations at various temperatures. Interactions between alloying elements and impurity elements are analyzed combining the thermodynamic and kinetics. Results show that low holding temperatures (below 680 °C) can significantly reduce the amount of introduced impurities. H13 steel has the smallest effect on the final purity of the molten Mg alloys and the presence of Cr can inhibit the dissolution of Fe into molten Mg alloys.

Published: July 2020

Herein, Mg–8Al–0.5Zn (AZ80) alloys with different Ce contents (0, 0.2, 0.8, and 1.4 wt%) are designed and prepared. The effects of the forging temperature (250, 300, 350, 400, and 450 °C), forging reduction (7.5%, 17.5%, 27.5%, and 37.5%), and Ce addition on the microstructure and compressive properties of the as‐forged AZ80 alloy are investigated. With increasing forging temperature, the compressive strength and fracture strain increased due to grain refinement. With an increase in forging reduction, the yield strength and compressive strength were also improved under the action of fine‐grain strengthening and work hardening. The results finally reveal that the appropriate forging temperature was 400 °C, and the optimized forging reduction was 27.5%. The addition of Ce significantly refined the grains of the as‐forged AZ80 alloys, and with addition of 1.4 wt% Ce, the grain size was significantly reduced by ≈42.0%. AZ80 alloys with Ce addition obtain remarkable grain refinement effects due to the existence of the Al4Ce phase. The results of tensile tests show that Ce addition effectively improves the tensile properties ascribed to the excellent grain refinement and work hardening effect.

Authors: Liang Shunxing
Published: July 2020

Herein, an extensive review of the design of titanium alloys with low elastic modulus as implant materials is provided. Due to the high specific strength, low elastic modulus, fatigue resistance, anticorrosion, biocompatibility, and so on, titanium alloys are good biomaterials, especially implant materials. Although lots of titanium alloys are developed for implant materials, the development of new titanium alloys that is toxic‐element free and elastic modulus close/comparable with the bone is still one of the recent and future research focuses. Thus, herein, the effect of elastic modulus on implants, the progress of titanium alloys with low elastic modulus, the toxicity of various alloying elements, and design methods of titanium alloys with low elastic modulus are reviewed. In addition, the development direction of the design method of titanium alloys with a low elastic modulus and the focus of future research are pointed out in the last section.

Published: July 2020

Brachiaria humidicola (BH) (syn. Urochloa humidicola) is an important forage grass in the tropics due to its capacity to grow in nutrient‐deficient soils, tolerate waterlogging, and inhibit soil nitrification. A major objective of BH breeding is to improve its nutritional quality. Therefore, a rapid and low‐cost method is needed to assess main quality parameters such as neutral detergent fiber (NDF), acid detergent fiber (ADF), in vitro dry matter digestibility (IVDMD), and crude protein (CP). This study developed models using near infrared reflectance spectroscopy (NIRS) to predict concentrations of these parameters toward breeding. Samples were collected from BH trials located in different regions of Colombia, scanned for NIRS (400–2,500 nm), analyzed with wet chemistry as reference values, and used to build the chemometric models. Results from wet chemistry showed wide variability in terms of dry matter percentage for NDF (51.6–76.2%), ADF (26.1–46.1%), IVDMD (41.5–78.3%), and CP (2.8–12.8%). The NIRS models were validated using an independent set of samples and have coefficients of determination (R2) and one minus the variance ratio (1 – VR) values in the range of .9 and .95, suggesting a good correlation between reference‐lab and NIRS‐predicted values. The standard errors of cross validation (SECV) for IVDM, NDF, ADF, and CP were 1.59, 1.18, 0.74, and 0.53%, respectively. Prediction efficiency (ratio of performance to standard deviation, RPD) for all parameters was above 3.0, except for CP (2.6). Calibrations obtained present an adequate adjustment and predictive tendency, making them suitable for selection and BH breeding.

Background

Badin, North Carolina, hosted an aluminum smelting plant from 1917 to 2007. The Concerned Citizens of West Badin reported suspected excess cancer mortality among former employees. This study aimed to investigate these concerns.

Methods

The study cohort was enumerated from United Steel Workers’ records of workers employed from 1980 to 2007. Cause‐specific mortality rates in the cohort were compared with North Carolina population mortality rates using standardized mortality ratios (SMRs), standardized by age, sex, race, and calendar period. We estimated cause‐specific adjusted standardized mortality ratios (aSMRs) using negative controls to mitigate healthy worker survivor bias (HWSB). Standardized rate ratios (SRRs) were calculated to compare mortality rates between workers ever employed vs never employed in the pot room.

Results

All‐cause mortality among Badin workers was lower than in the general population (SMR: 0.81, 95% confidence interval [CI]: 0.71‐0.92). After adjusting for HWSB, excesses for all cancers (aSMR: 1.55, 95% CI: 1.10‐2.21), bladder cancer (3.47, 95% CI: 1.25‐9.62), mesothelioma (17.33, 95% CI: 5.40‐55.59), and respiratory cancer (1.24, 95% CI: 0.77‐1.99) were observed. Black males worked the highest proportion of their employed years in the pot room. Potroom workers experienced higher respiratory cancer (SRR: 2.99, 95% CI: 1.23‐7.26), bladder cancer (SRR: 1.58, 95% CI: 0.15‐15.28), and mesothelioma (SRR: 3.36, 95% CI: 0.21‐53.78) mortality rates than never workers in the pot room.

Conclusions

This study responds to concerns of a group of former aluminum workers. The results, while imprecise, suggest excess respiratory and bladder cancers among pot room workers in a contemporary cohort of union employees at a US smelter.
