Market Correlation: Effect of Historical Events on the World\u27s Largest Financial Centers from 1983-2003

This paper studies the effect of various historical events on the market correlation among the three largest financial centers of the world: New York City, London, and Tokyo for the time period 1983-2003. The analysis focuses on those correlations associated with four historical events: the U.S. stock market crash of 1987, the London IRA Bombing of 1990, the Asian Currency Crisis of 1997 (particularly the day the Thai Baht fell), and the September 11th, 2001 terrorist attacks of 2001. The purpose of this study was to provide additional information that will provide the investment community with insights about maintaining market stability during periods of economic crises. With this information, investors may be able to avoid large losses and hedge their systemic risk of global events. Market data associated with each historical event were analyzed using correlational and statistical procedures. Results suggest that, during times of economic crises, the S&P 500 and the FTSE 100 tend to be more correlated with each other than with the Nikkei 225. At the end of the tested time period, the September 11th terrorist attack shows a similar correlation among the markets although the degree of correlation is slightly less. However, the fact that their correlations are very similar shows that there have not been significant changes in market correlation during economic crises over time

Adaptive Mode Matching in Advanced LIGO and Beyond

The era of gravitational wave astronomy was ushered in by the LIGO (Laser Interferometer Gravitational-Wave Observatory) collaboration with the detection of a binary black hole collision [2]. The event that shook the foundation of space-time allowed mankind to view the cosmos in a way that had never been done previously. Since then, another remarkable event was found by the LIGO and Virgo detectors where two neutron stars collided, sending both gravitational and electromagnetic waves to earth [3]. LIGO was built with the purpose of detecting the ripples in space-time caused by astrophysical events with the hopes of understanding the complexities hidden within the cosmos. In 2011, the primary stages of Advanced LIGO were installed and commissioned to start the first observing run (O1). During the writing of this thesis, the detectors had hardware replaced in order to mitigate noise from scattered light and new optics which reduced the losses from absorption. The upgrades were in preparation for the third observing run (O3) and the work presented here is primarily focused on experimental techniques for operating at higher power and mode matching Gaussian beams in the dual-recycled Michelson interferometer for the Advanced LIGO era and beyond. The first two chapters discuss the fundamentals of gravitational waves and the LIGO detector configurations. The third chapter introduces the reader to fundamentals in mode matching Gaussian laser beams. The fourth and fifth chapter summarizes the author\u27s work at Syracuse University. The sixth chapter deals with work at the LIGO Hanford observatory with an emphasis on mode sensing and high-power operation

Magnetism of cobalt nanoclusters on graphene on iridium

The structure and magnetic properties of Co clusters, comprising from 26 to 2700 atoms, self-organized or not on the graphene/Ir(111) moir\'e, were studied in situ with the help of scanning tunneling microscopy and X-ray magnetic circular dichroism. Surprisingly the small clusters have almost no magnetic anisotropy. We find indication for a magnetic coupling between the clusters. Experiments have to be performed carefully so as to avoid cluster damage by the soft X-rays

Building the Workforce of Tomorrow: Blockchain Curriculum in Higher Education

Although blockchain is a relatively new concept, it has become an important part of various industries such as fintech, healthcare, real estate, and supply chain. Thus, it is essential to educate the workforce of tomorrow on this new technology to ensure that students are prepared for the challenges of the competitive job market after graduation. This study aims to start a dialogue on curriculum innovation in higher education by examining current trends and course offerings. We analyzed 266 R1 and R2 institutions in the US and found that only a small number of them offer such courses. Thus, our next steps would be to provide some guidance for curriculum innovation, as well as pedagogical strategies that can reflect the dynamic nature of the IS field

Understanding Inservice Middle School Teachers’ Views of Nature of Science (VNOS)

The Nature of Science (NOS) is a component of science literacy that supports critical thinking around science concepts, speaking to how and why science is conducted and connected to creating data and evidence. NOS is designed to be more than the standardized lessons of science; it helps children critically analyze and solve real-world and societal issues using scientific knowledge. The interpretation of science varies between the ideology and beliefs of each individual. Given the importance of this idea, it is necessary that teachers be able to provide NOS opportunities to students; however, first, they must have a firm grasp of the concept. To that end, we have created a qualitative study using the Views of Nature of Science (VNOS-D+) questionnaire to understand how a group of middle school science teachers conceptualize the NOS. The VNOS-D+ was administered to a cohort of teachers and administrators (n=23) within a Large Urban School District. The data was analyzed using the VNOS key and then open-coded by three reviewers. The results found that participants had an emergent and developing understanding of the NOS and should be supported to develop a robust NOS perspective. Given this finding, future research, professional development, and educational curriculums should support teachers to continually engage with NOS explicitly and implicitly to grow their understanding of the topic

Integrated spatial multiplexing of heralded single photon sources

The non-deterministic nature of photon sources is a key limitation for single photon quantum processors. Spatial multiplexing overcomes this by enhancing the heralded single photon yield without enhancing the output noise. Here the intrinsic statistical limit of an individual source is surpassed by spatially multiplexing two monolithic silicon correlated photon pair sources, demonstrating a 62.4% increase in the heralded single photon output without an increase in unwanted multi-pair generation. We further demonstrate the scalability of this scheme by multiplexing photons generated in two waveguides pumped via an integrated coupler with a 63.1% increase in the heralded photon rate. This demonstration paves the way for a scalable architecture for multiplexing many photon sources in a compact integrated platform and achieving efficient two photon interference, required at the core of optical quantum computing and quantum communication protocols.Comment: 10 pages, 3 figures, comments welcom

Evaluating HPV Vaccination Adherence Amongst Teenagers Ages 12-18

Human papillomavirus (HPV) is a sexually transmitted infection that can cause genital warts and different cancers. According to the CDC, 85% of people will get an HPV infection in their lifetime. HPV infections have decreased significantly since the implementation of the HPV vaccine. Data has shown 90% of cancers caused by HPV can be prevented with administration of HPV vaccination. Current guidelines recommend vaccination administration as early as 9 years of age. This quality improvement project will evaluate HPV vaccination rates amongst teenagers ages 12-18

Sensing Optical Cavity Mismatch with a Mode-converter and Quadrant Photodiode

We present a new technique for sensing optical cavity mode mismatch and alignment by using a cylindrical lens mode converting telescope, radio-frequency quadrant photodiodes, and a heterodyne detection scheme. The telescope allows the conversion of the Laguerre-Gauss bullseye mode (LG01) into the 45° rotated Hermite-Gauss (“pringle”) mode (HG11), which can be easily measured with quadrant photodiodes. We show that we can convert to the HG basis optically, measure mode mismatched and alignment signals using widely produced radio-frequency quadrant photodiodes, and obtain a feedback error signal with heterodyne detection
