Cybersecurity policy and the Trump administration
No full textThis article evaluates the conditions under which national cybersecurity policy changes or remains stable. Consistent with theories of policy and bureaucratic inertia, particularly punctuated equilibrium theory (PET), it finds that national-level cybersecurity policy during the Trump administration was constrained by existing conceptual, political, and strategic commitments. It uses government and media documentation to observe two pivotal policy periods during the Trump administration. It finds that despite shifting from a nominally defensive to a nominally offensive posture, rather than revise policy categories and priorities, policy makers interpreted cyber threats within existing threat and policy categories. These findings offer two contributions to policy scholarship. First, they begin the process of situating the Trump administration in the larger context of US cybersecurity policy. Second, they demonstrate constraints on senior policy makers as well as the utility of a punctuated equilibrium model. The Trump administration’s “defending forward” concept represented one of the most ambitious efforts to break with existing US cybersecurity policy; however, even this effort was constrained in ways consistent with punctuated equilibrium theory.Journal ArticlePre-prin
Sanctuary cities and counties for the unborn: The use of resolutions and ordinances to restrict abortion access
No full textCity councils and county commissions are being asked to pass resolutions and ordinances that designate its specific locality as a “sanctuary for the unborn.” Some declare life begins at conception, ban abortion services (including access to emergency contraception like Plan B), classify abortion as murder with malice aforethought, label pro-choice organizations as criminal enterprises, and create civil causes of action against abortion providers and those who assist women in obtaining an abortion.
The article examines the movement pushing local governments to create sanctuary status across the country. Most of the localities that have enacted the ordinances and resolutions have small populations and do not have abortion clinics
The future of fragarance: An analysis of volatiles in citrus perfumes
No full textCitrus Greening: A citrus-killing virus that has been detrimental to Florida’s citrus production. This virus causes a yellow splotching of the leaves. It is spread by an insect called psyllids that feed on citrus plants. Once infected plants experience premature fruit drop, among other things.
Citrus-Perfumes: Many cosmetic products have switched to using natural ingredients due to a trend in ‘clean beauty’. Modern citrus perfumes will be tested organoleptically and by
SPME-GCMS to determine if they contain mainly synthetic volatiles (due to citrus greening, or a clean beauty trend). Perfume volatiles can be compared to standard fruit oils to determine the authenticity of citrus profile used
Technology development for quantum: A university-industry applied research project
No full textThe growing interest in the quantum realm has contributed to the creation of many startups working to make the next strides in quantum computing. Many big-name companies like Microsoft and IBM have made great strides in this realm. There are now easier ways to work with quantum because of the cloud quantum computers that are now available, for example, Azure Quantum. But physical quantum computers are less accessible because of their size and cooling requirements. We at Guided Particle are working in partnership with other research groups (Purdue University for example) to create a small form quantum source. We are currently working on our quantum source, and creating a smaller form than has been done by other
research groups. The end goal is to have an underwater drone that is self-sufficient and running on quantum. It would have the ability to create fluid models using fluid dynamic modeling and be able to measure contaminants in water. But with this iteration of the project, I focused on quantum computing and quantum computing for fluid dynamics
Short-term Euro-Dollar exchange rate forecasting using regression models
No full textIn this project, our goal is to investigate mathematical and statistical models to forecast the short-term exchange rate. Notably, we are considering the 15-minutes time frame Euro-Dollar (EUR/USD) currency pair as the object of the project.
There are several different major currency pair such as EUR/USD USD/JPY, GBP/USD, USD/CHF, AUD/USD, and USD/CAD.
We chose EUR/USD since it is the most traded currency pair in the market; however, most of our work can be applied to other currency pair with some modifications.
In addition, we will also focus on polynomial regression models, which we hypothesized to be a better fit given the non-linear nature of the data
Oracle SQL For Secure Relational Databases
No full textA typical Oracle database has multiple users working simultaneously. Data is shared amongst the users, and this of course leads to security concerns. This book comes in from the angle of developing and maintaining a secure Oracle database with multiple users. The book shows how data can be shared in an orderly fashion and what a good secure database is. In this book, we assume that you are acquainted with basic Oracle SQL and fundamentals of relational databaseBookPublishe
Practical guide to using SQL in Oracle: 3rd edition
No full textOracle is a widely used database engine. Due to its popularity, more and more schools and training organizations are using Oracle in their database courses to teach database principles and concepts. Given the current technological climate, the computer industry needs application developers who can write Oracle SQL code efficiently. This book employs a step-by-step systematic approach to learning Oracle SQL.
The current technological climate has generated a need for a concise book on Oracle/SQL programming tied to database principles and concepts. This book hopes to meet that need. It starts by presenting simple Oracle SQL concepts and slowly moves into more complex query development and PL/SQL. It also introduces SQL/XML. Each chapter includes numerous examples, which readers can assemble and execute themselves using Oracle. Each chapter ends with a series of exercises to reinforce and build on chapter material. In doing these exercises, we have provided a path for readers to learn SQL and the underlying principles of relational database.BookPublishe
Stroke disparities in Florida: Examining the relationship between county classification, age-adjusted stroke mortality rates, and the presence of primary strok
No full textAlthough overall stroke mortality has declined in the United States for decades, recent data show that this decline in stroke deaths has slowed and that stroke remains 1 of the leading causes of death at the state level (1). In Florida, stroke is the fifth leading cause of death and was responsible for 12,602 deaths in 2017. Florida’s death rate is 38.9 per 100,000 population and, in 2021, it is tied with Illinois at 20th place in stroke-related death rate rankings by state (2).
As part of an effort to improve the quality of care provided to stroke patients, primary stroke centers were created with a strict set of criteria for certifying hospitals that meet predefined standards (3) with the goal of stabilizing and providing emergency care for acute stroke patients (4). With these goals in mind, a patient is admitted to a primary stroke center or a comprehensive stroke center based on the severity of stroke symptoms. Although comprehensive stroke centers are equipped to provide care for complex stroke patients who often have more advanced therapeutic needs, primary stroke centers are equipped to provide care for less complex stroke patients and can administer acute stroke thrombolysis in a timely manner.
Having limited or no access to stroke centers remains a major challenge for many stroke patients. In the US, the scarcity of stroke centers is more pronounced in rural areas (5). In Florida, a rural county is a county with either 1) a population of 75,000 people or less, or 2) a population of less than 125,000 people and contiguous with a county that has a population of less than 75,000 people (6). By this definition, 30 out of the 67 counties in Florida are rural (7) and they contain 8.8% of Florida’s population (8). Considering the importance of stroke centers, a gap exists in the literature assessing the relationship between county classification, age-adjusted stroke mortality rates, and the number of primary stroke centers in Florida.
The purpose of our research was to create maps that illustrate the relationship between age-adjusted stroke mortality rates and the presence of primary stroke centers in Florida. We hypothesized that stroke mortality will be higher in regions of Florida with fewer primary stroke centers.Journal ArticlePublishe
Greenhouse gases and biogeochemical diel fluctuations in a high-altitude wetland
No full textThe landscapes of high-altitude wetland ecosystems are characterized by different kinds of aquatic sites, including ponds holding conspicuous microbial life. Here, we examined a representative pond of the wetland landscape for dynamics of greenhouse gases, and their association with other relevant biogeochemical conditions including diel shifts of microbial communities' structure and activity over two consecutive days. Satellite image analysis indicates that the area of ponds cover 238 of 381.3 Ha (i.e., 62.4%), representing a significant landscape in this wetland. Solar radiation, wind velocity and temperature varied daily and between the days sampled, influencing the biogeochemical dynamics in the pond, shifting the pond reservoir of inorganic versus dissolved organic nitrogen/phosphorus bioavailability, between day 1 and day 2. Day 2 was characterized by high dissolved organic nitrogen/phosphorus and N₂O accumulation. CH₄ presented a positive excess showing maxima at hours of high radiation during both days. The microbial community in the sediment was diverse and enriched in keystone active groups potentially related with GHG recycling including bacteria and archaea, such as Cyanobacteria, Verrucomicrobia, Rhodobacterales and Nanoarchaeaota (Woesearchaeia). Archaea account for the microbial community composition changes between both days and for the secondary productivity in the water measured during day 2. The results indicate that an intense recycling of organic matter occurs in the pond systems and that the activity of the microbial community is correlated with the availability of nutrients. Together, the above results indicate a net sink of CO₂ and N₂O, which has also been reported for other natural and artificial ponds. Overall, our two-day fluctuation study in a representative pond of a high-altitude wetland aquatic landscape indicates the need to explore in more detail the short-term besides the long-term biogeochemical variability in arid ecosystems of the Andes plateau, where wetlands are hotspots of life currently under high anthropogenic pressure.Journal ArticleArticle # 14437
Increasing human papillomavirus vaccination in a federally qualified health center organization using a systems‑based intervention integrating EHR and statewide immunization information system
No full textPublic acceptance of the HPV vaccine has not matched that of other common adolescent vaccines, and HPV vaccination rates remain below the Healthy People 2020 target of 80% compliance. The purpose of this study was to evaluate the capacity of nine pediatric clinics in a Federally Qualified Health Center organization to implement a systems-based intervention targeting office staff and providers using EHRs and a statewide immunization information system to increase HPV vaccination rates in girls and boys, ages 11 to 16 over a 16-month period. System changes included automated HPV prompts to staff, postcard reminders to parents when youths turned 11 or 12 years old, and monthly assessment of provider vaccination rates. During the intervention, 8960 patients (11–16 yo) were followed, with 48.8% girls (n=4370) and 51.2% boys (n=4590). For this study period, 80.5% of total patients received the first dose of the HPV vaccine and 47% received the second dose. For the first dose, 55.5% of 11 year old girls and 54.3% of 11 year old boys were vaccinated. For ages 12 to 16, first dose
vaccination rates ranged from the lowest rate of 84.5% for 14 yo girls up to the highest rate of 90.5% for 13 yo boys. Logistic regression showed age was highly significantly associated with first dose completion (OR 1.565, 95% CI 1.501, 1.631) while males did not have a significant association with first dose completion compared to females. The intervention increased overall counts of first and second HPV vaccination rates.Journal ArticleFinal article publishe
