This paper solves several mathematics problems listed in Vector Analysis by H. B. Phillips

The Hoffer and Osmond Theory and Treatment of Schizophrenia

Dr. Abram Hoffer and Dr. Humphrey Osmond have formulated a biochemical theory of schizophrenia based on a defective adrenal metabolism which results in the production of neurotoxins in the schizophrenic\u27s body. They have also developed a therapy for schizophrenia consisting of massive daily does of Vitamin B-3 (nicotinic acid) and other supplements. They detect schizophrenia by means of a chemical test (paper chromatography) and a psychological test (the Hoffer-Osmond Diagnostic test)

Education of the Senses by the Montessori Method

Maria Montessori (1870-1952), the first Italian woman M.D., was one of the great germinal pioneers in studying the intellectual development of the young child. Her philosophy of education (incorporated into the Montessori Method) is that only through movement and manipulation, through thinking with the senses and remaining active, does the child proceed to later abstract thinking. Thus, it is essential that the development of the senses be started early

The Development of the Slide Rule

Although the slide rule has been used extensively in business, industry, and science only in recent years, it is not a modern invention. Since the slide rule is a mechanical device whereby the logarithms of numbers may be manipulated, the slide rule of today was made possible over three and one-half centuries ago by John Napier, Baron of Merchiston in Scotland. In 1594, Napier privately communicated his results to Tycho Brake, a Danish astronomer, but did not publicly announce his system of logarithms until 1614. Napier set forth his purpose

The European Union “Software Patents” Directive: What Is It? Why Is It? Where Are We Now?

This paper has been adapted from a presentation given by the author at Duke University School of Law\u27s Hot Topics in Intellectual Property Law Symposium on April 1, 2005. It first presents an overview of the EU Software Patents Directive and many of the amendments that have been proposed and adopted. It then suggests a number of ways in which Europe can lead the world in developing a system that balances the interests of patent protection and open-source software

The power of a single large shareholder in Iberianfirms: friend or for?

Agency costs as a result of the separation of ownership and control within a firm can be a hurdle to the performance and profitability. It has been suggested that these costs can be reduced by the presence of a single large shareholder monitoring management and their decisions. On the contrary it has also been argued that a large shareholder negatively affects firm performance by deriving personal benefits from the firm and making suboptimal decisions. This research aims to investigate the relationship between the profitability of a firm and the level to which the shares of that firm are concentrated into a single shareholder. A random effects GLS panel regression is used to determine the effect of a large shareholder being present in Spanish and Portuguese firms by studying firms listed on these bourses over the period 2005 – 2014. The results show that a large shareholder has a negative influence in the Portuguese market, and no statistically significant effect in the Spanish market

The Multisecretary Problem with Continuous Valuations

\cite{Arlotto2019} showed that regret in the multisecretary problem is bounded, both in the number of job openings, $n$, and the number of applicants, $k$, provided that the applicant valuations have finite support. I study what happens when applicant valuations have continuous support. Specifically, I show that the regret grows like $\log(n)$ when valuations are drawn from a standard uniform distribution. So the regret, while not finite, still grows very slowly. However, the mechanism is completely different in this setting: the agent makes a finite number of costly mistakes in the discrete case, but makes an infinite number of nearly costless mistakes in the continuous case

Developing a Flexible System for a Friendly Robot to Ease Dementia (FRED) Using Cloud Technologies and Software Design Patterns

In this work, we designed two prototypes for a friendly robot to ease dementia (FRED). This affordable social robot is designed to provide company to older adults with cognitive decline, create reminders for important events and tasks, like taking medication, and providing cognitive stimulus through games. This project combines several cloud technologies including speech-to-text, cloud data storage, and chat generation in order to provide high level interactions with a social robot. Software design patterns were employed in the creation of the software to produce flexible code base that can sustain platform changes easily, including the framework used for the graphical user interface (GUI) and the database platform being used to store user data. The first prototype was developed on an Android-based system with an Arduino. This system was found to be expensive, unreliable, and difficult to develop on. The second prototype was therefore developed for a Raspberry Pi programmed using Python. Multiple tests with potential users were conducted in order to assess the capabilities and usability of the software created. These user tests showed overall satisfaction with the usability, and provided useful feedback for improving the software and expanding the capabilities of FRED
