Academic literature on the topic 'Eyeglasses in literature'

Someone reading empirical research relating human genetics to personal outcomes must be careful to distinguish two types of work: An old literature on heritability attempts to decompose cross-sectional variation in observed outcomes into unobservable genetic and environmental components. A new literature measures specific genes and uses them as observed covariates when predicting outcomes. I will discuss these two types of work in terms of how they may inform social policy. I will argue that research on heritability is fundamentally uninformative for policy analysis, but make a cautious argument that research using genes as covariates is potentially informative.

Abstract This study explores the representation and use of Victorian visual aids, specifically focusing on how the design of spectacle and eyeglass frames shaped ideas of the ‘normal’ and ‘abnormal’ body. It contributes to our understanding of assistive technologies in the Victorian period by showcasing the usefulness of material evidence for exploring how an object was produced and perceived. By placing visual aids in their medical and cultural context for the first time, it will show how the study of spectacle and eyeglass frames develops our understanding of Victorian society more broadly. Contemporaries drew upon industrialization, increasing education, and the proliferation of print to explain a rise in refractive vision ‘errors’. Through exploring the design of three spectacle frames from the London Science Museum’s collections, this study will show how the representations and manufacture of visual aids transformed in response to these wider changes. The material evidence, as well as contemporary newspapers, periodicals, and medical texts, reveal that visual aids evolved from an unusual to a more mainstream device. It argues that visual aids are a unique assistive technology, one that is able to inform our understanding of how Victorians measured the body and constructed ideas of ‘normalcy’ and ‘abnormalcy’.

Popularized in Spain through the work of the Italian satirist Traiano Boccalini, the motif of the occhiali politici, or political lenses, is one of the most understudied conceits in early modern Spanish satire. This essay examines four early modern Spanish texts where anteojos de larga vista (“eyeglasses” or “telescopes”) become central elements as the eye is given the ability to perceive the reality beyond deceptive appearances. But a capacity to see beyond reveals two parallel concerns: the adoption of spectacles as a mark of social distinction by a society suffering from the moral blindness these novels denounce and the increasing tensions between astronomy and religion stemming from the use of lenses as stargazing tools. Contextualizing these anxieties in the contemporary polemics regarding the divulgation of Galileo's Copernican theses, I illustrate how a simple corrective instrument triggered a fierce debate at the center of Spain's uneven modernity.

Introduction. Literature confirms that refractive errors are the most common, easily corrected, eye morbidity in children with disabilities. Early intervention such as wearing eyeglasses can positively impact the lives of these children. The implication of vitamin D status is investigated as a possible proactive measure in eye conditions. Aim. The current study proposed to asses the refractive status as well as vitamin D plasmatic level in 161 children. Another aim was to investigate whether myopia corelates with a lower plasmatic vitamin D level. Methods. A retrospective case-control study was done on 161 children, divided into two groups: the study group (children with disabilities) and the contol group (children without disabilities). The age range of children included in the study was from 5 to 16 years old. Results. Refractive errors were found to be more frequent in the group of children with disabilities and of these, astigmatism was the most frequent refractive disorder identified. Also, the plasmatic vitamin D level was found to be lower in those with myopia reguardless of disability status. Conclusions. Children with disabilities are diagnosed with refractive errors twice more frequenty than their healthy peers. Parents, medical staff and teachers should be aware of this risk factor and be more attentive because the presence of uncorrected refractive disorders may not be visible in most children, especially those with special needs.

Purpose This paper aims to investigate how the physical and sensory environmental triggers interact with subjective consumer evaluations in the production of shopping experiences, an under-investigated theme, despite its relevance. Design/methodology/approach An interpretative multi-method approach was used by combining video observation with camera eyeglasses and in-depth interviews with 30 customers of a department store. Findings Results offer a holistic framework with four-dimensional axial combination involving physical comfort, psychological comfort, physical product evaluation and sensorial product evaluation. Based on this framework, results highlight the role of comfort and products in producing shopping experience in ordinary store visits. Research limitations/implications The findings contribute both to consumer experience studies and to the retail marketing literature in shading a light on experience production in ordinary store visits. Specifically, we detail these visits not as a static response to a given environment stimulus, but as a simultaneous objective and subjective combination able to produce experience. Practical implications The results encourage managers to understand the experience production not just as an outcome of managerially influenced elements, like décor or odor. It involves considering subjective elements in the design of consumers’ physical and sensorial retail experiences. Originality/value Adopting an innovative method of empirical data collection, results generated a framework that integrates the objective shopping environment and subjective consumer responses. This research considers the role of comfort and product features and quality both physically and sensorially to develop experiences in a holistic manner in ordinary shopping visits.

(1) Background: Indoor air pollution can affect the well-being and health of humans. Sources of indoor pollution with particulate matter (PM) are outdoor particles and indoor causes, such as construction materials, the use of cleaning products, air fresheners, heating, cooking, and smoking activities. In 2017, according to the Global Burden of Disease study, 1.6 million people died prematurely because of indoor air pollution. The health effects of outdoor exposure to PM have been the subject of both research and regulatory action, and indoor exposure to fine particles is gaining more and more attention as a potential source of adverse health effects. Moreover, in critical situations such as the current pandemic crisis, to protect the health of the population, patients, and staff in all areas of society (particularly in indoor environments, where there are vulnerable groups, such as people who have pre-existing lung conditions, patients, elderly people, and healthcare professionals such as dental practitioners), there is an urgent need to improve long- and short-term health. Exposure to aerosols and splatter contaminated with bacteria, viruses, and blood produced during dental procedures performed on patients rarely leads to the transmission of infectious agents between patients and dental health care staff if infection prevention procedures are strictly followed. On the other hand, in the current circumstances of the pandemic crisis, dental practitioners could have an occupational risk of acquiring coronavirus disease as they may treat asymptomatic and minimally symptomatic patients. Consequently, an increased risk of SARS-CoV-2 infection could occur in dental offices, both for staff that provide dental healthcare and for other patients, considering that many dental procedures produce droplets and dental aerosols, which carry an infectious virus such as SARS-CoV-2. (2) Types of studies reviewed and applied methodology: The current work provides a critical review and evaluation, as well as perspectives concerning previous studies on health risks of indoor exposure to PM in dental offices. The authors reviewed representative dental medicine literature focused on sources of indoor PM10 and PM2.5 (particles for which the aerodynamic diameter size is respectively less than 10 and 2.5 μm) in indoor spaces (paying specific attention to dental offices) and their characteristics and toxicological effects in indoor microenvironments. The authors also reviewed representative studies on relations between the indoor air quality and harmful effects, as well as studies on possible indoor viral infections acquired through airborne and droplet transmission. The method employed for the research illustrated in the current paper involved a desk study of documents and records relating to occupational health problems among dental health care providers. In this way, it obtained background information on both the main potential hazards in dentistry and infection risks from aerosol transmission within dental offices. Reviewing this kind of information, especially that relating to bioaerosols, is critical for minimizing the risk to dental staff and patients, particularly when new recommendations for COVID-19 risk reduction for the dental health professional community and patients attending dental clinics are strongly needed. (3) Results: The investigated studies and reports obtained from the medical literature showed that, even if there are a wide number of studies on indoor human exposure to fine particles and health effects, more deep research and specific studies on indoor air pollution with fine particles and implications for workers’ health in dental offices are needed. As dental practices are at a higher risk for hazardous indoor air because of exposure to chemicals and microbes, the occupational exposures and diseases must be addressed, with special attention being paid to the dental staff. The literature also documents that exposure to fine particles in dental offices can be minimized by putting prevention into practice (personal protection barriers such as masks, gloves, and safety eyeglasses) and also keeping indoor air clean (e.g., high-volume evacuation, the use of an air-room-cleaning system with high-efficiency particulate filters, and regularly maintaining the air-conditioning and ventilation systems). These kinds of considerations are extremely important as the impact of indoor pollution on human health is no longer an individual issue, with its connections representing a future part of sustainability which is currently being redefined. These kinds of considerations are extremely important, and the authors believe that a better situation in dentistry needs to be developed, with researchers in materials and dental health trying to understand and explain the impact of indoor pollution on human health.

Binary regression models generally assume that the response variable is measured perfectly. However, in some situations, the outcome is subject to misclassification: a success may be erroneously classified as a failure or vice versa. Many methods, described in existing literature, have been developed to deal with misclassification, but we demonstrate that these methods may lead to serious inferential problems when only a single evaluation of the individual is taken. Thus, this study proposes to incorporate repeated and independent responses in misclassification binary regression models, considering the total number of successes obtained or even the simple majority classification. We use subjective prior distributions, as our conditional means prior, to evaluate and compare models. A data augmentation approach, Gibbs sampling, and Adaptive Rejection Metropolis Sampling are used for posterior inferences. Simulation studies suggested that repeated measures significantly improve the posterior estimates, in that these estimates are closer to those obtained in a case with no misclassifications with a lower standard deviation. Finally, we illustrate the usefulness of the new methodology with the analysis about defects in eyeglass lenses.

The purpose of this study was to know the factor that can be improved in the financial performance of Nasho. Nasho is a brand that focuses on offering products for eyeglass and helmet application that can be water, dew and dust repellent by utilizing the application of nanotechnology in the scope market of Bandung. However, to adapt the technology for Nasho is currently hampered by the limited capital to develop the technology itself. The company needs to manage the capital and minimize the cost to optimize the finance. The company needs to control the cost and expenses to avoid the high number of costs and expenses in terms of the development business stage. The research will use a qualitative approach by conducting interviews to Mr. Reza optics that will cooperate with Nasho to sell the product and use secondary data information from literature review, journal, books and primary data from financial history of Nasho and survey from the consumer of Nasho namely College student, Medical staff and Motorcycle riders and the components that are relevant to the conceptual framework. Survey used to get the consumer product and buying tendency information from Nasho’s consumer to validate the assumption of brand, price and buying intencity. Interview was conducted to get the suitable number of sales that are being used for cash flow forecasting scenario. The findings of this research is Nasho had low financial performance in the first two years of the business. After the evaluation, this can be improved by making a financial planning mix for short term and long term using the capital budgeting method in the form of three optimal scenarios of cash flow, Net Present Value (NPV), IRR and payback period that can be used as an optimal plan to run this business for the next five years.
