Enlightened Romanticism: Mary Gartside’s colour theory in the age of Moses Harris, Goethe and George Field

The aim of this paper is to evaluate the work of Mary Gartside, a British female colour theorist, active in London between 1781 and 1808. She published three books between 1805 and 1808. In chronological and intellectual terms Gartside can cautiously be regarded an exemplary link between Moses Harris, who published a short but important theory of colour in the second half of the eighteenth century, and J.W. von Goethe’s highly influential Zur Farbenlehre, published in Germany in 1810. Gartside’s colour theory was published privately under the disguise of a traditional water colouring manual, illustrated with stunning abstract colour blots (see example above). Until well into the twentieth century, she remained the only woman known to have published a theory of colour. In contrast to Goethe and other colour theorists in the late 18th and early 19th century Gartside was less inclined to follow the anti-Newtonian attitudes of the Romantic movement

Fatal Familial Insomnia: An Overview

Fatal Familial Insomnia (FFI) is an insidious prion disorder that tends to manifest itself as a patient reaches middle age following a pattern consistent with autosomal dominance. A wide range of symptoms are represented, many related to motor function and autonomic regulation, but degeneration of certain areas of the thalamus is present in every case. Genetically, the condition is transmitted only within families, but it has been demonstrated by Jackson et al. (2009) that FFI can be transmitted by exposure to/ingestion of infected material. A number of groundbreaking studies are discussed. These include the initial documentation of FFI as a prion disorder by Medori et al. (1992), the identification of codon 129 on PRNP as a locus for prion disease susceptibility by Palmer et al. (1991), the discovery that the aberrant isoform PrPsc requires the normal PrP protein in order to produce infectivity by Mallucci et al. (2003), and others. There are no effective treatments for FFI as of yet; scientists are still searching for all the pieces to the puzzle

Financial Repression, Bank Deposits, Real Assets and Black Money

Consider real assets and bank deposits. If returns on deposits improve due to reduction in financial repression, then investment in real assets can fall. However, if role of black money in real asset (secondary) market falls, then investment in the primary market can rise. So financial development will occur if the effect of reduction in financial repression is stronger than that of reduction of black money. This is shown in a model, with forced sales (due to liquidity shock), and strategic sales of real assets (under asymmetric information). Under some conditions, price is irrelevant for strategic trades.

Analysis of the Coupling of Wavelength-Shifting Fibers to Organic Liquid Scintillator Filled Fluoropolymer Tubes for Industrial and Nuclear Security Applications

Industrial and nuclear security applications continue to push radiation detection development into new and exciting frontiers. In this work, an innovative detection module is developed and tested for use in a cosmic ray imaging (CRI) system designed for oil field characterization and is evaluated for its potential use in a fast neutron detection system for nuclear security applications. By measuring density changes in the reservoir, the CRI system will provide real-time information about steam chamber development during the enhanced oil field recovery process known as steam assisted gravity drainage (SAGD). The ability to monitor the development of the steam chamber region has the potential to provide important information, which could be used to optimize the growth and uniformity of the underground steam chamber and minimize costs. The organic liquid scintillator based detection modules also detect fast neutrons. During the initial characterization of an unidentified radioactive source, it is important to have the capability to determine if special nuclear material (SNM) is present and if it is configured to produce a nuclear yield. The emission of multiple neutrons during a single fission makes it possible to use this unique timing characteristic to identify SNM. The number of specialists trained to handle nuclear devices is limited making this determination a critical step in properly responding to the situation. The detector module consists of a 5 mm diameter by 2-meter long fluoropolymer tube filled with organic liquid scintillator (OLS), optically read-out using wavelength shifting (WLS) fibers. The 1:400 ratio of diameter to length makes light collection from the organic scintillator very challenging. Over ten configurations of OLS, fluoropolymer tubes, and WLS fibers were tested. The final configuration consisted of two 2mm BCF-91A WLS fibers optically coupled to the outside of an optically transparent fluorinated ethylene propylene (FEP) tube filled with a commercial OLS (EJ-309). Cosmic ray muons produce large light pulses in the OLS of which a portion reaches the external WLS fibers. The WLS fibers re-emits the light at longer wavelengths and acts as a multi-mode light guide channeling the signal to photomultiplier tubes located at each end of the WLS fibers. This module demonstrated excellent detection efficiency with less than 5% signal reduction, at any point along the module, due to optical attenuation. Timing analysis of the WLS fiber signals also provided coarse position determination, 40 cm, which opens design options not previously available. An important characteristic required of neutron detectors for nuclear security applications is the ability to discriminate fast neutron and gamma ray events. Initial tests have demonstrated the capability of our module to discriminate neutron and gamma rays by applying the rise time pulse shape discrimination (PSD) method to the WLS fiber signals. EJ-309 is well known for its PSD capabilities. Coupling this desirable characteristic with loss free, low attenuation optical read-out through a WLS fiber has the potential to broaden significantly liquid scintillator applications

Corporate governance and Competition: A Case Study of India.

The aim of this paper is to show the interaction effect of product market competition and corporate governance variables on firm performance. While the linkage between internal governance mechanism and firm performance is well established in several studies, the interaction between internal and external governance mechanism has received very little attention in emerging market economies. Here we have shown the independent and interaction effect of ownership and competition variable on firm level productivity. Contrary to conventional wisdom, we document that competition has in reality become a discernible force in developing economies. The econometric modeling result confirms while the standalone effect of ownership variable on productivity is mostly insignificant, there is a strong positive interaction effect with competition variables.

Exploring Technology Usage at Home and the Relationship to the Development of the Tripod Grasp in Kindergarten Age Students

This research explored the development of the tripod/pincer grasp of 16 Kindergarten aged students and the activities these children engaged in when at home, with particular focus on fine motor and technology usage (both passive and interactive). This research used a mixed methods approach, using both classroom observations and a survey filled out by parents of participating students. This research fills a gap in existing research regarding the link between technology use and fine motor control in young children, as very little currently exists. The research found that fine motor activities at home helped facilitate the development of the tripod/pincer grasp at school, whereas large amounts of time spent engaging in passive technologies did not. The research also found that interactive technology was helpful only if the child utilized a stylus over their finger
