Safety assessment and biochemical evaluation of the effect of biogenic silver nanoparticles (using bark extract of C. zeylanicum) on Rattus norvegicus rats
Authors: Alwan Shukrya , Al-Saeed Muna , Abid Hussein
Published: July 2021

Background: Biosynthesized silver nanoparticles (AgNPs) are widely used in various biomedical applications. However, limited reports are currently available about the safety of biofabricated AgNPs using Cinnamomum zeylanicum bark extracts.
Objectives: The current study is aimed to assess the potential toxicity of biosynthesized AgNPs (using C. zeylanicum) by subacute oral administration in experimental rats.
Methods: AgNPs were biofabricated using methanol extract of C. zeylanicum bark and characterized by scanning electron microscopy (SEM) and atomic force microscopy (AFM). Twenty-four Rattus norvegicus female rats were divided into 4 groups (6 animals per group) as follows: Group-I was the control, while groups II, III, and IV were given 0.85, 1.76 and 3.53 mg/kg doses of AgNPs, respectively for 14 consecutive days. After 14 days of oral administration of AgNPs, serum levels of malondialdehyde (MDA), superoxide dismutase (SOD) and catalase (CAT) were measured using an ELISA technique. Serum concentrations of urea, creatinine, aspartate transaminase (AST) and alanine transaminase (ALT) were also determined as well as histopathologic features of the liver and the kidney.
Results: AgNPs did not induce any changes in mean body weight, biochemical parameters (AST, ALT, urea and creatinine), oxidative stress biomarkers (MDA, SOD and CAT) and histopathologic features (of the liver and kidneys) of the treated groups when compared to control group.
Conclusions: Our findings suggest that the oral administration of biogenic AgNPs (biofabricated using methanol extract of C. zeylanicum) to rats at a specific dose is relatively safe and does not show any signs of toxicity.
Pharmacological Treatment of Tachyarrhythmias in Acute Myocardial Infarction - a Review
Authors: Deaconu Alexandru , Deaconu Silvia , Radu Andrei , Dorobantu Maria
Published: July 2021

Acute myocardial infarction (AMI) causes severe metabolic and electrophysiological changes that induce silent or symptomatic life-threatening arrhythmias. Ventricular arrhythmias and atrial fibrillation are common during the early phase of AMI and are also important prognostic factors. Rapid identification and treatment of these arrhythmias can be life-saving, since in-hospital mortality rises dramatically in patients who develop arrhythmias with a fast ventricular rate following an AMI. Along with myocardial revascularization, adequate pharmacological therapy of hemodynamically relevant arrhythmias is generally useful. Since there are no controlled randomized trials comparing different antiarrhythmic drugs (AADs) in AMI, optimal decision making is based on medical societies guidelines recommendations and clinical judgement.
Survival, Functional Capacity and Quality of Life after Transcatheter Aortic Valve Implantation: Present Considerations and Future Perspectives
Authors: Radulescu Crina-Ioana , Deleanu Dan , Chioncel Ovidiu
Published: July 2021

Severe aortic stenosis (AS) is the most common valvular heart disease, with an increasing prevalence due to age-related degenerative modifications of the valve. Once AS becomes symptomatic, the survival of patients is significantly reduced with an annual mortality rate of 25%. Depending on surgical risk, anatomical and technical aspects, and the patient’s option, correction can be made either by surgical valve replacement (SAVR) or by transcatheter aortic valve implantation (TAVI). Although aortic valve implantation brings relief of symptoms, there is little data on the quality of life (QoL) of patients undergoing TAVI and the factors that directly influence it. Even if age and comorbidities are known modifiers of survival, there is no specific tool to assess the impact of AS and to determine the appropriate treatment strategy.

Published: July 2021

Left ventricle dysfunction is the link between the heart morphological changes and the overt heart failure. Hypertension is one of the main cardio-vascular conditions which can lead to development of left ventricle failure. The study was conducted at outpatient Clinic – Medlife, Memorial Hospital. It intended to compare NT-pro BNP and the ratio E/E’ as markers of diastolic dysfunction in hypertensive patients and normal ejection fraction (EF) and no signs or symptoms of heart failure. Both indexes proved to reflect independently diastolic dysfunction in symptomatic patients with different cardiac diseases but not in asymptomatic hypertensive patients. It was a single-center observational study recruiting 40 participants (20 F 52–70 age, and 20 M 56–67 age). Natriuretic peptides are widely accepted as biomarkers in heart failure with reduced ejection fraction. NT-pro BNP proved to be a very good means of diagnosing exercise-related left ventricular dysfunction (LVD) showing that it could unveil a subclinical LVD, especially in patient with myocardial remodeling. The main goal of this study was to compare the values of NT-pro BNP and E/E’. We have found no correlation between NT-pro BNP and E/E’, both pre-exercise and post-exercise, demonstrating that the later was not a reliable means of diagnosing LVD at effort in aymptomatic hypertensive patients.
The Challenges of Tachycardia Induced Cardiomyopathy - a Case Report
Authors: Velcea Andreea Elena , Suran Maria Claudia Berenice , Vinereanu Dragos
Published: July 2021

Tachycardia-induced cardiomyopathy (TIC) is characterized by reversible left ventricular dysfunction caused by long-standing tachycardia. Treatment options for tachyarrhythmias causing TIC have evolved, especially the rhythm control strategies, ensuring a better and more sustainable control of the arrhythmia.

We report the case of a 46-year-old male presenting with acute heart failure, atrial fibrillation (AF) of unknown duration and severe left ventricular dysfunction, as well as left ventricular dilation. His medical history was relevant for atrial flutter treated with catheter ablation, hypertension, and frequent atrial ectopy for which he had been prescribed amiodarone. Coronary artery disease and other potential causes for left ventricular dysfunction were excluded with coronary angiography and cardiac magnetic resonance. Thus, the patient had a high suspicion of TIC. We opted for a rhythm control strategy, however, after a successful initial electrical cardioversion, he had AF recurrence a few days later, under classic heart failure medication and antiarrhythmics. Pulmonary vein isolation was then performed, with no complications. At the one-month follow-up visit the patient was arrhythmia-free and had a normal left ventricular ejection fraction, with a slightly enlarged left ventricle. We opted to continue the heart failure medication.

This case illustrates a typical case of AF induced TIC and the limited pharmacological options that exist for rhythm control, as well as the high efficacy of catheter ablation and value of imaging.

RESÚMEN
 
La nefrolitotomía percutánea (NLPC) es el tratamiento de elección para litos coraliformes y cálculos renales grandes (mayores de 2 cm). El acceso renal percutáneo se puede lograr ya sea guiado por ultrasonido o fluoroscopia. El método de elección depende de la formación y las preferencias personales. El ultrasonido tiene varias fortalezas como herramienta de intervención y ofrece varias ventajas sobre la fluoroscopía: es fácilmente disponible, portátil, relativamente barato así como la reducción de la exposición a la radiación. Si bien existe una curva de aprendizaje para dominar estas técnicas, su adopción puede conducir a una menor exposición a la radiación para los pacientes, urólogos y proveedores de servicios de salud auxiliares al realizar la nefrolitotomia percutánea.
 
Objetivos

El acceso guiado por ultrasonido para la nefrolitotomía percutánea (NLPC) es una técnica segura, efectiva, libre de radiación y de bajo costo que puede ser utilizada en cualquier hospital. Esta técnica requiere de entrenamiento estructurado el cual debe comenzar desde la residencia.
Resolving the productivity paradox of digitalised production
Authors: Dold Luzian , Speck Christian
Published: July 2021

Although Industry 4.0 and other initiatives predict widespread adoption of digitalised technology on the factory floor, few companies use new digitalised production technology holistically in their ecosystems; in practical implementation, companies often decide against digitalisation for financial reasons. This is due to a paradox (akin to the so called “productivity paradox”) caused by the complexity of value creation and value delivery within digitalised production. This article analyses and synthesises cross-disciplinary research using a grounded theory model, thus offering valuable insights for businesses considering investing in digitalised production. A qualitative model and an associated toolbox (complete with tools for practical application by business leaders and decision-makers) are presented to address organisational uncertainty and leadership disconnect that often contribute to the paradoxical gap between digital strategy and operational implementation.
Using Multilinear Feature Space to Accelerate CNN Classification
Authors: L .Vinagreiro Michel Andre , C. Kitani Edson , M. Lagana Armando Antonio , R. Yoshioka Leopoldo
Published: July 2021

Computer vision plays a crucial role in ADAS security and navigation, as most systems are based on deep CNN architectures the computational resource to run a CNN algorithm is demanding. Therefore, the methods to speed up computation have become a relevant research issue. Even though several works on acceleration techniques found in the literature have not yet been achieved satisfactory results for embedded real-time system applications. This paper presents an alternative approach based on the Multilinear Feature Space (MFS) method resorting to transfer learning from large CNN architectures. The proposed method uses CNNs to generate feature maps, although it does not work as complexity reduction approach. When the training process ends, the generated maps are used to create vector feature space. We use this new vector space to make projections of any new sample in order to classify them. Our method, named MFS-CNN, uses the transfer learning from pre trained CNN to reduce the classification time of new sample image, with minimal loss in accuracy. Our method uses the VGG-16 model as the base CNN architecture for experiments; however, the method works with any similar CNN model. Using the well-known Vehicle Image Database and the German Traffic Sign Recognition Benchmark we compared the classification time of original VGG-16 model with the MFS-CNN method and our method is, on average, 17 times faster. The fast classification time reduces the computational and memories demand in embedded applications that requires a large CNN architecture.
Stack and Deal: An Efficient Algorithm for Privacy Preserving Data Publishing
Authors: Thammanna Gowda Vikas
Published: July 2021

Although k-Anonymity is a good way to publish microdata for research purposes, it still suffers from various attacks. Hence, many refinements of k-Anonymity have been proposed such as ldiversity and t-Closeness, with t-Closeness being one of the strictest privacy models. Satisfying t-Closeness for a lower value of t may yield equivalence classes with high number of records which results in a greater information loss. For a higher value of t, equivalence classes are still prone to homogeneity, skewness, and similarity attacks. This is because equivalence classes can be formed with fewer distinct sensitive attribute values and still satisfy the constraint t. In this paper, we introduce a new algorithm that overcomes the limitations of k-Anonymity and lDiversity and yields equivalence classes of size k with greater diversity and frequency of a SA value in all the equivalence classes differ by at-most one.
The 5 Dimensions of Problem Solving using DINNA Diagram: Double Ishikawa and Naze Naze Analysis
Authors: Hamoumi Mohammed , Haddout Abdellah , Benhadou Mariam
Published: July 2021

Based on the principle that perfection is a divine criterion, process management exists on the one hand to achieve excellence (near perfection) and on the other hand to avoid imperfection. In other words, Operational Excellence (EO) is one of the approaches, when used rigorously, aims to maximize performance. Therefore, the mastery of problem solving remains necessary to achieve such performance level. There are many tools that we can use whether in continuous improvement for the resolution of chronic problems (KAIZEN, DMAIC, Lean six sigma…) or in resolution of sporadic defects (8D, PDCA, QRQC ...). However, these methodologies often use the same basic tools (Ishikawa diagram, 5 why, tree of causes…) to identify potential causes and root causes. This results in three levels of causes: occurrence, no detection and system. The research presents the development of DINNA diagram [1] as an effective and efficient process that links the Ishikawa diagram and the 5 why method to identify the root causes and avoid recurrence. The ultimate objective is to achieve the same result if two working groups with similar skills analyse the same problem separately, to achieve this, the consistent application of a robust methodology is required. Therefore, we are talking about 5 dimensions; occurrence, non-detection, system, effectiveness and efficiency. As such, the paper offers a solution that is both effective and efficient to help practitioners of industrial problem solving avoid missing the real root cause and save costs following a wrong decision.

Bonsai in the time of COVID
Authors: Mansourian Yazdan
Published: July 2021

The study sought to find out to what extent engagement with serious leisure, in this case, bonsai growing, can help people deal with challenging times, such as a global pandemic. In particular, how bonsai enthusiasts use their hobbies to manage uncertainty and stress during the lockdown and how they have shared their lived experiences on this topic via social media. The researcher employed a user-generated contents analysis approach to address the questions and explored a collection of comments from a sample of the most visited bonsai videos posted during the pandemic. The serious leisure perspective has been used as a theoretical framework to conceptualise the data based on the qualities that differentiate serious leisure from casual leisure. The findings showed that engagement in this hobby helps bonsai enthusiasts to develop social connectedness and cope with their stress caused by the pandemic.

Published: July 2021

As rodas de conversa são atividades de linguagem realizadas de modo permanente na Educação Infantil, com o intuito de desenvolver a oralidade, a expressão e a interação da criança. A roda de conversa é um método bastante utilizado, mas geralmente não é visto como uma prática pedagógica. Apesar disso, o seu objetivo é a construção de um espaço de diálogo que permita aos alunos se expressarem e aprenderem em conjunto. Para criar uma roda de conversa, o professor deve fazer um planejamento do conteúdo com um objetivo claro, estabelecer as regras e intervir quando necessário para garantir a compreensão dos alunos. Além disso, é necessário organizar um espaço adequado em que todos estejam confortáveis e possam se ver, assim como também escolher assuntos que possam ser desenvolvidos pela turma e trazer dados que possam auxiliar. É papel do professor dar voz ao que os alunos têm a dizer e deixar que todos participem, permitindo que eles digam o que pensam e o que sabem sobre o conteúdo.
can you hear me? by Simona Semenič and the question of no-longer-dramatic writing
Authors: Troha Gašper
Published: July 2021

In the article, the author analyses three plays by Simona Semenič that were published in the book can you hear me? (2017). At first sight, the three pieces appear to be written in Semenič’s now-familiar writing style with no punctuation marks or upper-case initials and no apparent division between dialogues and stage directions. Content-wise, however, the three plays differ significantly from the bulk of the playwright’s opus as they represent autobiographical texts which once again establish the character and more or less distinct dramatic action. The article focuses on two questions: Are these still no-longer-dramatic texts? And, what is the status of representation and performativity in them? By analysing the formal and content properties of the three texts, more precisely, through an analysis of the drama character, the relationship between dialogue and monologue and dramatic action, the author shows that indeed these texts establish recognisable dramatic characters and relatively strong dramatic action. In this, they move away from no-longer- dramatic texts as defined by Gerda Poschmann, even though their legacy is still very much present, e.g., in the fragmented writing style.
Growth performance and meat quality of meat-type guinea fowl fed different commercial diets
Authors: Batkowska Justyna , Drabik Kamil , Karwowska Małgorzata , Ahsan Umair , Raza Ifrah , Adamczuk Agnieszka , Horecka Beata
Published: July 2021

Abstract. The aim of study was to assess the growth performance, meat quality, and fatty acid composition of meat-type guinea fowl fed balanced commercial diets under two different feeding programs, similar to those for slaughter turkeys and broiler chickens, respectively. A total of 80 4-week-old meat-type guinea fowl divided into two groups (four replicates per group; 10 birds in each replicate) were raised for 14 weeks. One group received commercially available diets in a three-phased program (TM group), whereas the other group was fed commercial diets in a two-phased program (CM group). Growth-performance-related traits were recorded. At the end of rearing (14 weeks of age), eight birds from each group were slaughtered. Carcass yield and technological traits of meat (pH, color, water-holding capacity, natural and thermal loss, tenderness, fatty acid profile) were analyzed. Groups did not differ in terms of body weight as well as carcass yield and characteristics. There was no difference in meat quality and the fatty acid profile of breast and thigh meat of guinea fowl from TM and CM groups. The findings of this study suggest that both commercial diets (for broiler chickens and turkeys) can be used in meat-type guinea fowl rearing. Due to the lower price of diets fed to the CM group and the lack of significant variation in meat quality traits, its use seems to be more justified from an economic point of view.
The high-frequency response correction of eddy covariance fluxes – Part 1: An experimental approach and its interdependence with the time-lag estimation
Authors: Peltola Olli , Aslan Toprak , Ibrom Andreas , Nemitz Eiko , Rannik Üllar , Mammarella Ivan
Published: July 2021

Abstract. The eddy covariance (EC) technique has emerged as the prevailing method to observe the ecosystem–atmosphere exchange of gases, heat and momentum. EC
measurements require rigorous data processing to derive the fluxes that can be used to analyse exchange processes at the ecosystem–atmosphere
interface. Here we show that two common post-processing steps (time-lag estimation via cross-covariance maximisation and correction for limited
frequency response of the EC measurement system) are interrelated, and this should be accounted for when processing EC gas flux data. These findings
are applicable to EC systems employing closed- or enclosed-path gas analysers which can be approximated to be linear first-order sensors. These EC
measurement systems act as low-pass filters on the time series of the scalar χ (e.g. CO2, H2O), and this induces a time lag
(tlpf) between vertical wind speed (w) and scalar χ time series which is additional to the travel time of the gas signal in the
sampling line (tube, filters). Time-lag estimation via cross-covariance maximisation inadvertently accounts also for tlpf and hence
overestimates the travel time in the sampling line. This results in a phase shift between the time series of w and χ, which distorts the
measured cospectra between w and χ and hence has an effect on the correction for the dampening of the EC flux signal at high frequencies. This
distortion can be described with a transfer function related to the phase shift (Hp) which is typically neglected when processing EC
flux data. Based on analyses using EC data from two contrasting measurement sites, we show that the low-pass-filtering-induced time lag increases
approximately linearly with the time constant of the low-pass filter, and hence the importance of Hp in describing the high-frequency
flux loss increases as well. Incomplete description of these processes in EC data processing algorithms results in flux biases of up to 10 %, with
the largest biases observed for short towers due to the prevalence of small-scale turbulence. Based on these findings, it is suggested that spectral
correction methods implemented in EC data processing algorithms are revised to account for the influence of low-pass-filtering-induced time lag.
Increasing the spatial resolution of cloud property retrievals from Meteosat SEVIRI by use of its high-resolution visible channel: implementation and examples

Abstract. The modification of an existing cloud property retrieval scheme for
the Spinning Enhanced Visible and Infrared Imager (SEVIRI) instrument
on board the geostationary Meteosat satellites is described to utilize
its high-resolution visible (HRV) channel for increasing the spatial
resolution of its physical outputs. This results in products with a
nadir spatial resolution of 1×1 km2 compared to
the standard 3×3 km2 resolution offered by the
narrowband channels. This improvement thus greatly reduces the
resolution gap between current geostationary and polar-orbiting
meteorological satellite imagers. In the first processing step,
cloudiness is determined from the HRV observations by a
threshold-based cloud masking algorithm. Subsequently, a linear model
that links the 0.6 µm, 0.8 µm, and HRV
reflectances provides a physical constraint to incorporate the spatial
high-frequency component of the HRV observations into the retrieval of
cloud optical depth. The implementation of the method is described,
including the ancillary datasets used. It is demonstrated that the
omission of high-frequency variations in the cloud-absorbing
1.6 µm channel results in comparatively large
uncertainties in the retrieved cloud effective radius, likely due to
the mismatch in channel resolutions. A newly developed downscaling
scheme for the 1.6 µm reflectance is therefore applied
to mitigate the effects of this scale mismatch. Benefits of the
increased spatial resolution of the resulting SEVIRI products are
demonstrated for three example applications: (i) for a convective
cloud field, it is shown that significantly better agreement between
the distributions of cloud optical depth retrieved from SEVIRI and
from collocated MODIS observations is achieved. (ii) The temporal
evolution of cloud properties for a growing convective storm at
standard and HRV spatial resolutions are compared, illustrating an
improved contrast in growth signatures resulting from the use of the
HRV channel. (iii) An example of surface solar irradiance, determined
from the retrieved cloud properties, is shown, for which the HRV channel
helps to better capture the large spatiotemporal variability induced
by convective clouds. These results suggest that incorporating the HRV
channel into the retrieval has potential for improving Meteosat-based
cloud products for several application domains.

Abstract. We present 20-year flask sample records of atmospheric CO2, δO2/N2 and APO from the stations Lutjewad (the Netherlands) and Mace Head (Ireland) and a 3-year record from Halley station (Antarctica), including details of the extensive calibration procedure and its stability over time. The results of our inter-comparison involving gas cylinders from various research laboratories worldwide also show that our calibration is of high quality and compatible with the internationally recognised Scripps scale. The measurement records from Lutjewad and Mace Head show similar long-term trends during the period 2002–2018 of 2.31 ± 0.07 ppm yr−1 for CO2 and −21.2 ± 0.8 per meg yr−1 for δO2/N2 at Lutjewad, and 2.22 ± 0.04 ppm yr−1 for CO2 and −21.3 ± 0.9 per meg yr−1 for δO2/N2 at Mace Head. They also show a similar δO2/N2 seasonal cycle with an amplitude of 54 ± 4 per meg at Lutjewad and 61 ± 5 per meg at Mace Head, while CO2 seasonal amplitude at Lutjewad (16.8 ± 0.5 ppm) is slightly higher than that at Mace Head (14.8 ± 0.3 ppm). We show that the observed trends and seasonal cycles are compatible with the measurements from various stations, especially the measurements from Weybourne Atmospheric Observatory (United Kingdom). However, there are remarkable differences in the progression of annual trends between the Mace Head and Lutjewad records for δO2/N2 and APO, which might in part be caused by sampling differences, but also by environmental effects, such as the North Atlantic Ocean oxygen ventilation changes to which Mace Head is more sensitive. The Halley record shows clear trends and seasonality in δO2/N2 and APO, where especially APO agrees well with the continuous measurements at Halley by the University of East Anglia, while CO2 and δO2/N2 present slight disagreements, most likely caused by small leakages during sampling. From our 2002–2018 records, we find good agreement for the global ocean sink: 2.0 ± 0.8 PgC yr−1 and 2.2 ± 0.9 PgC yr−1, based on Lutjewad and Mace Head, respectively.

China’s Belt and Road Initiative (BRI), also known as One Belt, One Road (OBOR), was launched in 2013 by President Xi Jinping. BRI opens “gateway to opportunities” and establishes a new grand geopolitical strategy for regional development, international economic cooperation and new world order. To foster BRI, China hosted the second Belt and Road Forum for International Cooperation (BRF) in Beijing on 25-27 April 2019. New media tools including dedicated web pages and social media sources were utilised to promote the BRF 2019. Particularly, Twitter was used by government and media organizations to promote and share the proceedings of the event. Topics related to Belt and Road Initiative were trending on social media resulting in a wide reach and engagement. A large number of pertinent tweets appeared with trending hashtags such as #brf2019, #BeltandRoad and #BRI. Major contribution to this tweet activity came from politicians, government officials and media groups. This study analyses the trending hashtags #brf2019 and #BeltandRoad (N=20,727) on Twitter on the occasion of second BRF 2019 to understand the patterns of Twitter data. Specifically, this study attempts (1) to investigate how Twitter was used by media groups to promote the second Belt and Road Forum; (2) to identify top influencers to promote the second Belt and Road Forum; (3) to analyse overall sentiment towards the second Belt and Road Forum. The study follows mixed method for Social Media performance data by combining qualitative content analysis and sentimental analysis of tweets. All the tweets collected were publicly posted and were tracked using Twitter streaming API and Python programming language. For analysis, parameters such as; users, reach, impression, engagement, type of tweet, trending topics, source of tweets and main themes were analysed.

Authors: Nawaz Haq , Akbar Rafaqat Ali
Published: July 2021

Teaching methods are primary elements of curriculum. National curriculum provides for student-centered teaching methods including for the subject of physics. Focusing on the importance of teaching methods, the current quantitative study was planned to explore student-centered teaching methods used for physics curriculum implementation. The sample of the study comprised 2,880 science students selected through multistage sampling technique. Self-constructed questionnaire having 4-factors; small group discussion, project work, inquiry teaching and debate were used to collect the data from the respondents. The questionnaire was validated from the experts and pilot tested to ensure Cronbach’s Alpha reliability statistics; .823. The data were analyzed through descriptive statistics and independent sample t-test. Results declared that teachers were making 56% use of student-centered teaching methods. Furthermore, urban secondary schools’ teachers were making more use of student-centered teaching as compared to rural secondary schools’ teachers for curriculum implementation. Based on the results, it is recommended that physics teachers should be provided training in student-centered teaching methods for effective curriculum implementation.
Covid 19 Pandemic, Vaccination—Rural, Urban and Religious Perspectives
Authors: Shenoy Veena , Mahendher Sheetal , Hemani Shubham
Published: July 2021

The purpose of this paper is to understand the ideologies, intent, and reasoning which prompt the millennials to take or shun the vaccine. The study incubates Rural, Urban and Religious sentiments that affect the preferences of inoculation, modify our decision-making process toward mass immunizations, and contribute to vaccine waste in many areas. We hope to convey the fear of not getting the vaccine as well as the elements that encourage folks to immunize themselves for the greater good in this study. Rural approach to vaccine hesitancy is fuelled by rumors, myths—whilst driven by limited access to the outside world. Urban vaccine hesitancy is driven by the abundance of information—giving rise to conspiracy theorists. Religious reluctance to vaccination is driven by notional norms opposing cure by modern treatment.
