Ethnography of communication
Authors: Karanfil Ferhat 
Published: November 2020

Ethnography of communication is an approach to discourse research that investigates the sequential organisation of talk as a way of accessing participants' understandings of, and collaborative means of organising the forms of social interaction. The objective of current research is to explore the speech of the education minister and how he uses his language indirectly talking on solid innovations. The sample online recordings of the education minister are transcribed in close detail to allow for a fine analysis of the design, exchange, and coordination of actions within the delivery of new implementations. This paper will introduce intellectual foundations of discourse analysis outline its approach to data collection and transcription; illustrate its analytical procedures; and discusses the application of ethnography of communication in the education minister’s speech while addressing the teachers. The results suggest that the use of indirectness and implicit speech making strategies foster the politeness act in public speech. We can conclude that the politicians’ speech delivered to the public may be researched more and it might be a part of discourse competence of English language learners. The future direction of ethnography of communication may focus on transnational context comparing the different countries and education minister’s speech which may help English teachers to teach culture and spoken discourse better.

Published: November 2020

Background: Iron tablets have many benefits such as reducing the risk of death during bleeding, preventing anemia, and increasing nutritional intake in the fetus. Pregnant women with adolescence are at higher risk of anemia and death than pregnant women of sufficient age. One impact that occurs due to the low consumption of iron tablets in teenage pregnant women is babies born with conditions such as low birth weight, normal weight, and overweight babies born.Objectives: This study to analyze the correlation between iron consumption tablets of adolescent pregnant women with the weight of new born.Methods: This research is a quantitative study that uses secondary data in the form of data from the 2017 IDHS. There are 692 teenage pregnant female respondents with variable consumption of iron tablets and birth weight of babies. Data analysis in the study used the Chi-Square test.Results: Teenage pregnant women who consume iron tablets by 70.8% and those who do not consume 29.2%. The category of babies born mostly at the weight of normal-born babies is 84.8%. While the low infant weight category is 10.7% with a fairly high amount. Chi-Square statistical test results showed a p value of 0.019 (p = 0.019 <0.05) and the Contingency Coefficient showed a value of 0.107.Conclusions: There was correlation between consumption of iron tablets in adolescent pregnant women with the weight of new born with the category of low birth weight babies, babies born normally and more babies born in Indonesia.Keywords: Iron tablets (Fe), teenage pregnant women, the weight of new born

Published: November 2020

The complication of inventory is a crucial problem for the company because inventory is one of the valuable assets for the company. The existence of inventory control is needed so the inventory levels that exist within the company is not in very large (optimal) therefore the costs incurred by the company can be suppressed as minimum as possible. PT NM is a company engaged in spare parts, especially branded cars in West Jakarta. The level of inventories of goods owned by these companies is high because The company did not want to experience stock out of stock but on one side the stock is large enough so the costs incurred by companies such as storage costs of goods becomes even greater. In order to control inventory levels, this study uses a Markov Chain method that can identify optimal inventory level and the expectation of profits earned per month by making estimates of the future demand a previous demand. From the research results shows expectation of profit of each state starting from state 2 to state 10 is Rp 13.146,98921; Rp 12.246,94064; Rp 11.346,61466; Rp 10.444,64569; Rp 9.534,074035; Rp 8.584,408534; Rp 7.484,413248; Rp 5.913,288143; Rp 3.211,609986,-. While the profit expectations that earned by the company per month is Rp 694.233,333, and the optimal inventory level is 50.

O mundo do trabalho convive com inédita velocidade de mudança nos formatos de exercício profissional. O Brasil não é exceção neste processo. O primeiro fator impulsionador dessas mudanças é a internacionalização das expectativas organizacionais. Parâmetros e critérios de comparação de tais expectativas deixaram de ser, sequer, regionais. O porte da empresa também não inibe mais a comparação internacionalizada. A constante demanda por integração às cadeias globais de produção, tanto na esfera produtiva, como na prestação de serviço, gera inevitável pressão de mudança nos regimes de trabalho. Buscar referência “além fronteiras” é só o primeiro novo formato nos regimes de trabalho.

Published: November 2020

In several production areas, dessert (sweet) and reinforced wines are made after a more or less intense dehydration of harvested grapes. The dehydration process depends on several factors, including the size, morphology and anatomy of the berries, all genetically defined traits that can be affected by vineyard management and microclimate conditions. At harvest, berry outer surface and skin ultrastructural features of cvs Aleatico, Sagrantino, Sangiovese and Trebbiano berries were investigated in a frozen-hydrated state using cryo‑scanning electron microscopy (Cryo‑SEM). The berries were subjected to postharvest dehydration at 23 °C for twelve days and the differences in weight loss were determined. In terms of weight loss rate, Aleatico and Trebbiano were the fastest and the slowest respectively. Therefore, the ultrastructural changes of berry skin of these two varieties were also investigated at the end of the dehydration process. At harvest, the structure of the epicuticular waxes on the skin outer surface differed between berries of different cultivars. The thickness of the cuticle, epidermis and hypodermis was also found to be significantly different, with Trebbiano berries having the thickest skin. At the end of the dehydration process all the measured parameters decreased, in particular Aleatico epicuticular wax, hypodermis and cuticle thickness, as well as the hypodermis cell wall and the mesocarp parenchyma cell area. The high weight loss rate recorded for Aleatico can be partly explained by the thickness of the berry skin at harvest, which was significantly thinner than that of Trebbiano, as well as by other skin-related morphological and histological factors possibly affecting permeability.
Shelf-edge delta and reef development on a mixed siliciclastic–carbonate margin, central Great Barrier Reef

Published: November 2020

ABSTRACT
The Great Barrier Reef (GBR) is the world's largest extant mixed silicilastic–carbonate margin. Previous research on the Great Barrier Reef has suggested that the extensive barrier reef system may act as an impermeable barrier and limit the development of delta systems during lowstands, but sufficient geophysical data to support this hypothesis are lacking. We use dense sparker seismic and sub-bottom profiler data to better understand the structure of a large lobe-shaped feature (∼ 10 km × 10 km) on the shelf edge of the central GBR and the interactions between siliciclastic and carbonate sedimentary systems. Interpreted sparker seismic contains prograding clinoforms and suggest that the lobe-shaped feature was a river-dominated shelf-edge delta. A delta on the shelf edge implies that the presence of an exposed barrier reef was not a major impediment to deposition and that other adjacent lobe-shaped features are also deltaic deposits. The shelf-edge deltas were deposited onto a broad upper-slope terrace that allowed continued progradation and limited incision when sea level fell below the shelf edge. Delta foresets are commonly colonized by coral reefs, but the spatial and temporal relationship between reefs and some deltaic units remains unclear. The presence of multiple shelf-edge deltas that link to previously mapped Burdekin River paleo-channels indicates a complex history of sedimentation, with the Burdekin River delta migrating up to 100 km along the GBR margin during the late Quaternary. Regional bathymetric data suggest that large modern or recent shelf-edge deltas are rare on the GBR and that there was a broad range of sedimentary processes operating along the margin of the GBR during periods of low sea level.
Refinement of the stratigraphic framework for the Regional C depositional unit of the McMurray Formation and implications for the early transgression of the Alberta Foreland Basin, Canada

Published: November 2020

ABSTRACTThe Lower Cretaceous McMurray Formation in Alberta and Saskatchewan, Canada, comprises a series of depositional units (DUs) consisting of stacked parasequences bounded by flooding surfaces and incised by fluvio-estuarine channel belts. The fluvio-estuarine channel belts of the McMurray Fm have been the focus of numerous studies whereas the regional DUs have received substantially less attention. Of the regional DUs, Regional C (equivalent to the middle McMurray) is the most understudied, yet this interval records the history of the McMurray Formation between deposition of fluvial strata in the lower McMurray and marine facies in the upper McMurray and overlying Clearwater Formation. Determining the history of the Regional C DU is fundamental for accurately reconstructing the stratigraphic evolution of the McMurray Fm and, by extension, the early evolution of the Alberta Foreland Basin.The Regional C is divided into two DUs separated by a regionally mappable flooding surface. This surface occurs 11 to 15 m below the top of the Regional C and is traceable over a 2,550 km2 area. This flooding surface divides the thick interval of undifferentiated Regional C into a lower C2 DU and an upper C1 DU, each with a maximum thickness of &lt; 15 m. The thickness of the C2 and C1 DUs indicates that deposition at this time also occurred in a setting of low to moderate accommodation creation, which is consistent with the rest of the McMurray Formation. The limited available accommodation space was easily surpassed by sediment supplied by the paleo-distributive channel system, leading to a basinward progradation of the shoreline.The C2 and C1 DUs are retrogradationally stacked, with the maximum regressive paleo-shoreline of C1 lying landward of that of C2. This stacking arrangement indicates that the shoreline backstepped during the early stages of transgression of the Boreal Sea. The backstepping of the paleo-shoreline from C2 to C1 time is consistent with previous studies that show continued and stepwise retrogradation and/or transgression of the paleo-shoreline from the onset of deposition in the lower McMurray Formation through to maximum transgression in the Clearwater Formation. Together, these studies demonstrate that the early drowning of the Alberta Foreland Basin was persistent and slow.
Development of inter-lava drainage systems in LIPs: The Columbia River Flood Basalt Province (U.S.A.) as a case study

Published: November 2020

ABSTRACT
Volcanism in large igneous provinces (LIPs) is understood to have had the potential to affect global environments and ecosystems, triggering mass extinctions, climate change, and ocean acidification. However, basin-scale studies sediment distribution and sedimentary-system development in LIP lava fields are sparse and often limited to localized exposure. To gain a better understanding of the controls on inter-lava sedimentology across a continental LIP, a new sedimentological data set is presented from the Miocene Columbia River Flood Basalt Province (CRBP), situated in the Columbia Basin in south-central Washington State, northeast Oregon and eastern Idaho. Based on the qualification and quantification of sedimentary facies, petrography, paleoflow, channel dimensions, and catchment size from 96 sites across the Columbia Basin, a refined model of regional and local environmental change, integrating local volcanic and tectonic evolution, is presented. Here, CRBP stratigraphy is divided into six distinctive sedimentation intervals, which allows correlation of sedimentary interbeds formed in the western part and in the eastern part of the basin. The model describes and reviews drainage-system development and discusses the control of volcanic and tectonic activity on sediment distribution in the CRBP lava field at local to basin scale. The data presented here largely support findings of previous works suggesting a highly complex interplay between sedimentary, volcanic, and tectonic evolution of the area. In addition, it elaborates on the aspects of sediment–lava interaction and indicates that individual sub-basins in the CRBP formed separated depositional settings, emphasizing the lateral complexity of inter-lava sedimentation. Importantly, this work improves our understanding of sediment–lava relationships in continental LIPs and helps in building more generic models for sediment distribution in volcanic terranes where exposure is limited or absent.
Induction of different human enteroendocrine cells in intestinal organoids
Authors: Clevers Hans , Beumer Joep 
Published: November 2020

Abstract

Intestinal enteroendocrine cells \(EECs) are key players in mammalian physiology as largest endocrine organ, and regulate metabolic processes such as insulin secretion and induction of satiety. EECs are rare cell types \(less than 1% of the epithelium) and produce a large number of different hormones making these challenging to study. Model systems to assess the differentiation and function of these essential cell types have been lacking. In a novel approach, we describe the induction of human EECs in intestinal organoids. Moreover, in the manuscript linked to this protocol, we describe that manipulating the BMP signaling pathway allows to induce expression of specific sets of hormones that correspond to the EEC state in the crypt-villus axis. This differentiation platform can be used to study the function of EECs and could contribute to the development of drugs for diabetes and obesity.

Published: November 2020

Abstract
After the COVID-19 worldwide spread, evidence suggested a vast diffusion of negative consequences on people's mental health. Together with depression and sleep difficulties, anxiety symptoms seem to be the most diffused clinical outcome. The current contribution aimed to examine attentional bias for virus-related stimuli in people varying in their degree of health anxiety (HA). Consistent with previous literature, it was hypothesized that higher HA would predict attentional bias, tested using a visual dot-probe task, to virus-related stimuli. Participants were 132 Italian individuals that participated in the study during the lockdown phase in Italy. Results indicated that the HA level predicts attentional bias toward virus-related objects. This relationship is double mediated by the belief of contagion and by the consequences of contagion as assessed through a recent questionnaire developed to measure the fear for COVID-19. These findings, indicative of attentional bias for virus-related cues, are discussed in the context of cognitive-behavioral conceptualizations of anxiety suggesting a risk for a loop effect. Future research directions are outlined.

Abstract
Here we present a straightforward unique molecular identifier (UMI)-linked nanopore consensus sequencing workflow (UMIC-seq), resulting in cost-effective and accurate long-read sequencing of amplicons. Short random molecular barcodes (i.e. unique molecular identifiers, UMIs) are attached to a pool of gene variants prior to nanopore sequencing to enable reliable clustering and the generation of accurate consensus sequences, even when starting from highly similar gene variants (e.g. a library of point mutants in directed protein evolution) that could not be reliably distinguished in the ordinary nanopore sequencing output.

Abstract
Background: Cough is a common symptom in childhood and is an important circumstance of inappropriate antibiotic use. This study aimed to investigate the non-prescription use of antibiotics for cough among children aged under 5 years.Methods: We conducted a community-based survey of under-5 children in Yiwu, China from October to November 2019. The subjects were enrolled from 14 townships using a two-stage stratified sampling procedure. Detailed information was collected through a face-to-face interview based on a standard questionnaire, and the children’s caregivers answered as agents. Univariable and multivariable logistic regression analyses were performed to explore the factors associated with nonprescription use of antibiotics for cough in children. Results: A total of 3102 children were included in the study, and 1211 children were reported to have a cough in the past month. Among them, 40.2% (487/1211) were medicated with antibiotics, and 18.7% (91/487) of these were unprescribed. Cephalosporins were the most frequently used antibiotic (52.8%), and community pharmacies were the main source (53.7%). Children who coughed for 1–2 weeks (OR=1.73, 95% CI=1.03-2.90) or 3–4 weeks (OR=2.39, 95%CI=1.08-4.97), with 2 or more accompanying symptoms (OR=2.44, 95% CI=1.14-5.72), or with a family annual income between 50000 and 100000 RMB (OR=4.14, 95% CI=1.41-17.69) had a higher risk of non-prescription use of antibiotics than those coughing for <1 week, without accompanying symptoms, or with family annual income <50000 RMB.Conclusions: Our findings indicated that a high proportion of infants and young children had been treated with antibiotics for cough, and nearly 1/5 of them were used without prescription. More public health campaigns and further health teaching on the appropriate use of antibiotics are needed to ensure the rational treatment of cough in children.

Abstract
Background: Dysmenorrhea is reported to be among the most common gynecological disorders worldwide. The current study aimed to determine the prevalence and management practices for dysmenorrhea among adolescent school girls in Nigeria. The study also aimed to determine the predictors for choosing a management option for dysmenorrhea.Methods: The study was a cross-sectional descriptive survey conducted in five conveniently selected secondary schools (high schools) in Enugu State. A 12-item questionnaire including a Visual Analog Scale was used to collect data. All data were analyzed using SPSS with significance set at p<0.05.Results: A total of 1,486 survey questionnaires were completed (88.45% response rate). The mean age of the study respondents was 15.26±1.517. The prevalence of dysmenorrhea was 51.1%. There was a significant difference (t =-6.299, p < 0.001) between the ages of the dysmenorrheic girls (15.50±1.466) and the ages of girls who were not dysmenorrheic (15.01±1.529). The mean age of Menarche was 12.64±1.450. Pain in the waist was the most common symptom reported among the respondents (57.4%, n = 853). More than one-third of the respondents reported that they take OTC medications for menstrual symptoms (31.8%, n = 472). Age and severity of dysmenorrhea significantly predicted the likelihood of taking a pharmacological agent for dysmenorrhea.Conclusion: Younger females were more likely to do nothing about menstrual pain. There is a need for adolescents to be educated on the safety and efficacy of different management options for dysmenorrhea early.
