Published: April 2021

PurposeStatistical charts are an essential source of information in academic papers. Charts have an important role in conveying, clarifying and simplifying the research results provided by the authors, but they present some accessibility barriers for people with low vision. This article aims to evaluate the accessibility of the statistical charts published in the library and information science (LIS) journals with the greatest impact factor.Design/methodology/approachA list of heuristic indicators developed by the authors has been used to assess the accessibility of statistical charts for people with low vision. The heuristics have been applied to a sample of charts from 2019 issues of ten LIS journals with the highest impact factor according to the ranking of the JCR.FindingsThe current practices of image submission do not follow the basic recommended guidelines on accessibility like color contrast or the use of textual alternatives. On the other hand, some incongruities between the technical suggestions of image submission and their application in analyzed charts also emerged. The main problems identified are: poor text alternatives, insufficient contrast ratio between adjacent colors and the inexistence of customization options. Authoring tools do not help authors to fulfill these requirements.Research limitations/implicationsThe sample is not very extensive; nonetheless, it is representative of common practices and the most frequent accessibility problems in this context.Social implicationsThe heuristics proposed are a good starting point to generate guidelines for authors when preparing their papers for publication and to guide journal publishers in creating accessible documents. Low-vision users, a highly prevalent condition, will benefit from the improvements.Originality/valueThe results of this research provide key insights into low-vision accessibility barriers, not considered in previous literature and can be a starting point for their solution.

Published: April 2021

PurposeThe aim is to reveal contemporary research trends and patterns in Internet of Things (IoTs) so that social scientists who are new to the discipline may be steered towards rightful directions when examining this phenomenon.Design/methodology/approachA total of 169 IoT articles indexed in the Web of Science database were analyzed via bibliometric analysis and content analysis. The VOSViewer software was used to identify popular keywords of the IoT topics, its publication productivity, the most relevant journals, and the most prolific authors within. Content analysis was conducted manually to determine the most popular research methods used, the most frequently studied contexts, the most popular IoT application areas, the most highly examined user perspectives, and the most often employed theories.FindingsThe synthesis of both the bibliometric and content analysis results suggest the necessity of investigating the post-adoption technology usage behavior of IoT technology in developing countries, particularly in smart home. This is especially so from new landscapes using other theories or models, apart from the overwhelmed Technology Adoption Model (TAM) and its variants.Originality/valueWith a focus on addressing the state-of-the-art of IoT in social science, and to synthesize its future research directions systematically, this study was conducted with both bibliometric and content analysis, in order to enhance the overall analysis for higher accuracy and more reliable results.

Published: April 2021

Purpose
The purpose of this study is to investigate the changes in the performance of ink formulations caused by the addition of compounds that improve the ink’s physical properties to achieve an optimum formulation for inkjet printing, because of the importance and simplicity of this method.

Design/methodology/approach
Ink samples were formulated using Acid Red 14 as ink colorant, different percentages of polymeric compounds including polyvinyl alcohol (PVA), polyvinylpyrrolidone and Carboxy methyl cellulose (CMC) as viscosity modifier compounds and surfactant as the surface tension enhancer. Formulated samples were adjusted in terms of fluid physical properties e.g. viscosity, density and surface tension, and the effect of used compounds on the improvement of both physical and colorimetric properties such as viscosity, surface tension, colorimetric coordinates and lightfastness has been evaluated to achieve the optimum printing inks to be printed on three different substrates.

Findings
The experimental observations showed that CMC was the most compatible compound as the viscosity modifier as its viscosity value was in the printable range of 2–22 cP. Moreover, a flow-curve test was applied to the ink samples and their Newtonian behavior was approved. Based on the spectrophotometric test results of printed samples, the samples containing PVA provided acceptable lightfastness in comparison to other ink samples on every used substrate.

Originality/value
An optimum relation between colorimetric coordinates of the printed samples and ink formulation could be considered and achieved.
To what extent are the underlying concepts of integrated reporting applicable for hi-tech knowledge-based organizations?
Authors: Mirsadri Seyed Mohsen , Bardinet-Evraert Frédérique , Evraert Serge 
Published: April 2021

Purpose
The purpose of this study is to examine the proper structure for the integrated reporting of hi-tech knowledge-based organizations (KBOs); in particular, the authors evaluate the appropriateness of the concept and elements of integrated reporting for hi-tech KBOs.

Design/methodology/approach
The study uses an exploratory sequential mixed-method approach, including an initial qualitative case study, then an instrument development phase (Delphi), and finally, a quantitative survey.

Findings
The resulting analysis concluded that hi-tech KBOs have the potential to prepare a simplified, integrated report. The organization overview, governance, business model, strategies and resource allocation, performance, opportunities and risks are the content elements relevant to be included in the hi-tech KBOs annual report. However, the organization’s future outlook is not confirmed to be included. Due to liability and competitive concerns, organizations do not provide targets, forecasts, projections or even scenarios.

Research limitations/implications
Focus on a single country and a small sample of interviewees participated.

Practical implications
This paper concludes that the existing integrated reporting framework is useful for different types of organizations, but with some modifications. In addition, it analyzes how directors of Iranian hi-tech KBOs perceive and value content elements of integrated reporting.

Social implications
This paper suggests that the fulfillment of corporate transparency for Iranian hi-tech KBOs can be achieved by the policymaker’s support on integrated reporting.

Originality/value
Iran is swiftly moving toward a knowledge-based economy, and hi-tech KBOs will become the powerhouse of the economy. It is important to understand how managers of Iranian hi-tech KBOs perceive and value integrated reporting. The previous practical studies are not focused on Iranian firms and the impacts of integrated reporting on hi-tech KBOs and its implementation and effectiveness had not been studied before.

Published: April 2021

AbstractHydrous pyrolysis (HP) practiced on type‐II kerogen‐bearing oil shale samples from the Sargelu Formation in the Ghali‐Kuh Area, western Iran, using a specially designed apparatus was performed at different temperatures (250–350°C), with hydrocarbon generation evaluated at each temperature. For comparison, the samples subjected to Rock‐Eval pyrolysis before proceeding to HP resulted in Tmax = 418°C, HI = 102, and TOC = 4.33%, indicating immaturity and hence remarkable hydrocarbon (especially oil) generation potential, making them appropriate for HP. Moreover, the samples were deposited in a low‐energy reductive marine environment, with maximum oil and gas generation (739 mg and 348 mg out of 50 g of rock sample, respectively) observed at 330°C and 350°C, respectively. The oil generated at 330°C was subjected to gas chromatography (GC) and isotopic analyses to assess hydrocarbon quality and composition. The hydrocarbon generation data was devised to estimate kinetic indices of the Arrhenius equation and to investigate the gas–oil ratio (GOR) and overall conversion yield. Based on the producible hydrocarbon quantity and quality, the findings contribute to the economic assessment of oil shales across the study area. The developed kinetic model indicates the history of hydrocarbon generation and organic matter (OM) maturity.
Epigenetic clock and methylation study of oocytes from a bovine model of reproductive aging

Published: April 2021

AbstractCattle are an attractive animal model of fertility in women due to their high degree of similarity relative to follicle selection, embryo cleavage, blastocyst formation, and gestation length. To facilitate future studies of the epigenetic underpinnings of aging effects in the female reproductive axis, several DNA methylation‐based biomarkers of aging (epigenetic clocks) for bovine oocytes are presented. One such clock was germane to only oocytes, while a dual‐tissue clock was highly predictive of age in both oocytes and blood. Dual species clocks that apply to both humans and cattle were also developed and evaluated. These epigenetic clocks can be used to accurately estimate the biological age of oocytes. Both epigenetic clock studies and epigenome‐wide association studies revealed that blood and oocytes differ substantially with respect to aging and the underlying epigenetic signatures that potentially influence the aging process. The rate of epigenetic aging was found to be slower in oocytes compared to blood; however, oocytes appeared to begin at an older epigenetic age. The epigenetic clocks for oocytes are expected to address questions in the field of reproductive aging, including the central question: how to slow aging of oocytes.

Published: April 2021

AbstractWe propose a new spatio‐temporal point process model to predict infectious cases of COVID‐19. We illustrate its practical use with data from six key cities in China, and we analyse the effects of natural and social factors on the occurrence and spread of COVID‐19. We show that large‐scale testing and strict containment are key factors for the successful suppression of the COVID‐19 contagion. This study provides an effective tool to develop early warning systems for major infectious diseases, offering insights on how to develop prevention and control strategies to reduce the impact of disease and maintain population sustainability.
Persistence of Operant Responding for Food After Prior Cocaine Exposure in Fischer 344 But Not Lewis Rats
Authors: Forouzan Shadab , Nieto Steven J. , Kosten Therese A. 
Published: April 2021

Background and ObjectivesChronic cocaine exposure has differential neural effects in Fischer 344 (F344) vs Lewis inbred rats that may explain strain‐dependent differences during acquisition vs maintenance of cocaine self‐administration. We assessed whether prior cocaine exposure alters operant responding for food across various phases (acquisition, maintenance, extinction, spontaneous recovery, reinitiation) in these strains.MethodsLewis and F344 rats (N = 12) were administered three cocaine (15 mg/kg) or saline injections at hourly intervals for 3 consecutive days. Beginning the next day for 24 days, rats had access to operant chambers in which one lever depression resulted in the delivery of a food pellet. Then, four extinction sessions were conducted in which food was no longer available, but other stimulus conditions remained the same. After a 2‐day break, spontaneous recovery was assessed over four sessions. Food delivery was then restored for 3 days to test reinitiation followed by a progressive ratio session.ResultsLewis rats acquired the operant faster than F344 rats. F344 rats showed lower maintenance rates than Lewis rats but higher spontaneous recovery responding. Cocaine exposure caused persistence of responding during extinction in F344 but not Lewis rats. All groups reinitiated responding when food was available again and did not differ in final ratios completed under the progressive ratio schedule.Discussion and ConclusionsThat prior cocaine exposure led to persistence of responding in F344 rats during extinction may reflect heightened contextual conditioning that interferes with the ability to extinguish responding.Scientific SignificanceResults have implications for the genetic contribution to relapse‐like behaviors.

AbstractIntroductionWomen who have undergone radical trachelectomy as a fertility‐sparing treatment for early‐stage cervical cancer may be at higher risk for retained tissues after early‐term miscarriage due to cervical cerclage or cervical necrosis. Dilatation and curettage or aspiration may present additional risks in these women. The aim of this study was to assess the efficacy of expectant management for early pregnancy miscarriage after radical trachelectomy.Material and methodsKeio University Hospital records were reviewed for women who conceived after abdominal radical trachelectomy and received perinatal care between 1 April 2012 and 31 March 2020. A total of 62 women (76 pregnancies) were identified, and 13 of these women experienced miscarriage before 12 gestational weeks. The management and outcome of these cases were reviewed in detail.ResultsThe median maternal age at miscarriage was 39 years (range 31–42 years) and the median duration from abdominal radical trachelectomy to conception was 2.60 years (range 0.49–7.30 years). Cervical necrosis before conception occurred in one case (8%). One patient requested treatment with aspiration and the remaining 12 cases were managed with observation for a median of 23 days (range 7–50 days). There were no cases of endometritis or cases requiring dilatation and curettage for residue tissue. Further, no cases developed laceration of the residual cervix and no loss of cerclage sutures after discharge was noted.ConclusionsExpectant management seems to be safe and appropriate for first trimester miscarriage after abdominal radical trachelectomy.

SummaryObesity increases the risk of chronic kidney disease in children. Our aim was to assess urinary podocalyxin (PCX) in children and adolescents with obesity as a potential marker of obesity‐related kidney disease (ORKD). The current case‐control study included 128 children with obesity compared to 60 non‐obese age and sex matched controls. Study population were subjected to full history taking as well as thorough physical examination. Urine samples for albumin creatinine ratio (uACR) and PCX were collected from the study population as well as blood samples for assessment of serum creatinine and fasting lipid profile. A statistically significant difference was found between cases and controls regarding urinary PCX (P < .001) and uACR (P = .021). A statistically significant positive correlation was found between uACR and weight SD score (SDS), body mass index SDS, waist circumference, estimated glomerular filtration rate, triglycerides (TG) as well as urinary PCX, whilst urinary PCX correlated significantly with obesity duration and uACR. Cases with microalbuminuria had a statistically significant higher waist circumference, waist‐hip ratio, fat percentage, TG and urinary PCX compared to those with normal uACR (P = .042, .034, .05, .018 and .036 respectively). Urinary PCX showed 83.3% sensitivity and 74% specificity in detection of albuminuria. Urinary PCX was increased significantly in children with obesity making it a potential sensitive marker of ORKD in children.

AbstractBackgroundHere, we evaluate the effects of a diet rich in low‐glycaemic index carbohydrates and fibre (CHO/Fibre diet) or monounsaturated fatty acids (MUFA diet), on fasting and postprandial adiponectin concentrations and their relationship with the beneficial effects of the experimental diets on postprandial glucose metabolism and liver fat in type 2 diabetes (T2D).MethodsFasting and postprandial adiponectin plasma concentrations were measured before and after dietary interventions in the participants to a randomized controlled trial (NCT01025856), wherein 37 men and 8 women with T2D, aged 35‐70 years, followed a CHO/Fibre diet or a MUFA diet for an 8‐week period. Hepatic fat content by 1H NMR and fasting and postprandial plasma glucose and insulin measurements were also available.ResultsFasting adiponectin plasma levels did not change after both diets. Postprandial adiponectin significantly increased after the CHO/fibre diet (9.9 ± 1.6 μg/mL vs. 10.8 ± 2.3 μg/mL; P = .033) but not after the MUFA diet (10.6 ± 1.8 μg/mL vs. 10.6 ± 1.6 μg/mL; P = .935) with a significant difference between changes (P = .035). In the combined CHO/Fibre and MUFA groups, fasting and postprandial adiponectin significantly and inversely correlated with postprandial insulin iAUC at baseline and after intervention, and with liver fat content after intervention.ConclusionsA diet rich in CHO/Fibre increased postprandial plasma adiponectin significantly more than a MUFA diet in patients with T2D. Independently of diet, adiponectin levels associated with postprandial insulin concentrations. The dietary interventions modulated the relationship between adiponectin and liver fat.

Published: April 2021

AbstractBackgroundHospital at Home (HaH) is a growing model of care with proven patient benefits. However, for the types of services required to provide an episode of HaH, full Medicare reimbursement is traditionally paid only if care is provided in inpatient facilities.DesignThis project identifies HaH services that could be reimbursable under Medicare to inform episodic care within fee‐for‐service (FFS) Medicare.SettingAll data are derived from acute services provided from the Mount Sinai HaH program between 2014 and 2017 as part of a Center for Medicare and Medicaid Innovation (CMMI) demonstration program.ParticipantsThe sample was limited to patients with one of the following five admitting diagnoses: urinary tract infection (n = 70), pneumonia (n = 60), cellulitis (n = 45), heart failure (n = 37), and chronic lung disease (n = 24) for a total of 236 acute episodes.MeasurementsHaH services were inventoried from three sources: electronic medical records, Medicare billing and itemized vendor billing. For each admitting diagnosis, four reimbursement scenarios were evaluated: (1) FFS Medicare without a home health episode, (2) FFS Medicare with a home health episode, (3) two‐sided risk ACO with a home health episode, and (4) two‐sided risk ACO without a home health episode.ResultsAcross diagnoses, there were 1.5–1.9 MD visits and 1.5–2.7 nursing visits per episode. The Medicare FFS model without home health care had the lowest reimbursement potential ($964–$1604) per episode. The Medicare fee‐for‐service within ACO models with home health care had the greatest potential for reimbursement $4519–$4718. There was limited variation in costs by diagnosis.Conclusion and RelevanceThough existing payment models might be used to pay for many HaH acute services, significant gaps in reimbursement remain. Extending the benefits of HaH to the Medicare beneficiaries that are likely to derive the greatest benefit will require new payment models for FFS Medicare.

AbstractBackground/ObjectiveAlopecia areata (AA) is a skin disease characterized by sudden‐onset hair loss. The relationship between psychiatric status and AA has not been fully elucidated. The aim of this study was to evaluate emotion dysregulation, somatization, depression, and anxiety levels in children and adolescents with AA.MethodsThe study included 27 patients aged 8–18 years diagnosed with AA, and an age and gender‐matched control group consisting of 30 cases without a known chronic medical disease. All individuals were screened for existing psychiatric illnesses by a pediatric psychiatrist through the Schedule for Affective Disorders and Schizophrenia for School‐Age Children Present and Lifetime Version (K‐SADS‐PL). The patients were then evaluated using the Children's Depression Inventory (CDI), Screen for Child Anxiety‐Related Emotional Disorders (SCARED), State‐Trait Anxiety Inventory for Children (STAI‐C), and Children Somatization Inventory (CSI‐24). In addition, the patients' parents were asked to complete the Emotion Regulation Checklist‐Family Form (ERC).ResultsWhen comparing the scale scores of the AA and control group, there was a statistically significant difference between the groups in terms of the Emotional Lability/Negativity subscale scores on ERC. K‐SADSPL ratios denoted features of at least one psychiatric condition in 62.9% and 16.6% of the AA group and control group, respectively.ConclusionsOur results emphasize the importance of psychiatric evaluation in patients with AA. Our study also reveals the need for further studies with a larger sample of AA patients being evaluated in terms of emotion regulation.
