Approximate Vanishing Ideal via Data Knotting

The vanishing ideal is a set of polynomials that takes zero value on the given data points. Originally proposed in computer algebra, the vanishing ideal has been recently exploited for extracting the nonlinear structures of data in many applications. To avoid overfitting to noisy data, the polynomials are often designed to approximately rather than exactly equal zero on the designated data. Although such approximations empirically demonstrate high performance, the sound algebraic structure of the vanishing ideal is lost. The present paper proposes a vanishing ideal that is tolerant to noisy data and also pursued to have a better algebraic structure. As a new problem, we simultaneously find a set of polynomials and data points for which the polynomials approximately vanish on the input data points, and almost exactly vanish on the discovered data points. In experimental classification tests, our method discovered much fewer and lower-degree polynomials than an existing state-of-the-art method. Consequently, our method accelerated the runtime of the classification tasks without degrading the classification accuracy.Comment: 11 pages; AAAI'1

Issues Regarding the Most Effective Tool of U.S. Bankruptcy Law

This thesis addresses three areas in which there have been important developments concerning the automatic stay of the U.S. Bankruptcy law, provided by 11 U.S.C. § 362. The first part of the thesis addresses and analyses the question whether state courts have jurisdiction to determine their own jurisdiction when the automatic stay is at issue. The consensus, however, now seems to favor the traditional and correct view, that while bankruptcy courts alone have jurisdiction to lift or modify the stay, state courts, have jurisdiction to determine whether the stay does or does not cut off its jurisdiction to reach the merits of a case. The second topic is whether a state court has jurisdiction to impose sanctions for an alleged violation of the stay. The analysis, with the help of case laws will show that even if a state court or another federal court has jurisdiction to determine whether the stay applies, only the bankruptcy court where the case is pending has jurisdiction to impose sanctions for violating the stay. The third part of the thesis explains and analyses issues concerning repossession of property by a creditor before the filing of a bankruptcy petition

A Study of Personality and Student Involvement on the College Campus

This study examined optimism and locus of control and their relationship to student involvement on and off-campus. The participants were 94 undergraduate students, male and female, ages 18 to 22. Participants completed three scales; Optimism Scale, Locus of Control Scale, and Involvement Scale. The results were analyzed using a correlational matrix. Optimism was significantly related to student involvement. Locus of control, contrary to predictions, was not significantly related to student involvement. Conclusions are drawn about optimism’s role in student involvement and about how student involvement may increase optimism

Impromptu Domesticity: Housing Adaptations by the Marshallese in Springdale, AR

This study analyzes the relationship between people and their spatial environment through the lens of cultural practices and experiences. By using theories of cultural identity and activity patterns to compare spatial usage in two differing circumstances, this study will help to better understand the spatial needs of Marshallese living in Springdale, Arkansas. The analysis uses two in-depth interviews to establish a base of qualitative data to understand the unique needs of this specific population. Through constructs such as spatial fluidity, sharing culture, and ability to adapt to new spatial practices, the two cases are compared to one another in order to understand each case’s specific circumstances

Callosal Malformations: Developmental Impacts and Parental Adjustment During the COVID-19 Pandemic

In March 2020 the 2019 coronavirus disease (COVID-19) was determined to be a global health crisis (Lee et al., 2021). As the virus continued to spread rapidly, individuals had to adjust their daily routines to reduce disease transmission. Agenesis of the Corpus Callosum (AgCC) is a broad term used when there is a presence of congenital brain malformation in the region of the brain responsible for transmitting information to both left and right hemispheres (Paul, 2011). Evaluation of individuals with AgCC have been observed to demonstrate specific deficits including cognitive efficiency, transfer of sensory-motor information, and complex reasoning (Brown & Paul, 2019; Mangum, 2018; Miller et al., 2018) although evolve over time (Badderudin et al. 2007; Paul et al., 2007). Developmental evaluations have demonstrated generalized delays in individuals ranging from age 2-16 years, when compared to those without AgCC (Eddy, 2022). The purpose of this study was to discover whether adaptive development in children aged 6 through 13 years varied based on parent reported Major Life Events (MLE) and COVID-19 pandemic related change. A total of 30 parents of a child with a confirmed anatomic diagnosis of AgCC completed the Vineland Adaptive Behavior Scales, Third Edition in addition to the MLE and/or COVID-19 questionnaire. Results of the retrospective cross-sectional study showed generalized delays across all developmental domains compared to the normative sample. In the communication domain, delays were found to be more apparent when parent-reported stress and impact was also elevated. COVID-19 related change was also identified in the areas of reduced in-person social interaction, delivery of education, and increased parent responsibility. This study broadly identified environmental events as identifiable developmental risk factors

The Effects of Postpartum Hemorrhage Simulation

Postpartum hemorrhage (PPH) is the leading cause of maternal morbidity and mortality worldwide. Evidence supports the importance and impact simulation has had on preparation for postpartum hemorrhage. Preparation with hands-on education is imperative for a safe outcome during a real-life hemorrhage situation. Lack of frequent education and simulation can equate to negative outcomes for all involved. The purpose of this project was to increase exposure to a safe environment to explore knowledge and skills during a postpartum hemorrhage event. This quality improvement project surveyed postpartum nurses pre and post-mock postpartum hemorrhage simulation. The setting allowed for mistakes, discussion, and open communication among staff. Before the simulation, participants self-reported not feeling prepared for a PPH should it occur in their nursing unit. Post-simulation revealed enhanced readiness for PPH, increased awareness of agency policy and protocols for PPH, and a desire for more hands-on, practice experience to ensure positive outcomes for both patients and staff

Improving service quality in small communities: The Bahamas as a model

Service quality is a topic that permeates every facet of the tourism industry. In small communities such as The Bahamas, where tourism is the driving factor for economic stability, service quality is paramount. In 2001, the Bahamian Ministry of Tourism set customer satisfaction goals for the country and is continually striving to improve the country\u27s visitor satisfaction ratings through market research; This qualitative exploratory study investigates service quality in Bahamian hotels and was inspired by Ministry of Tourism customer service research. The project was tailored to identify service quality gaps within the Bahamian hotel industry by applying the Conceptual Gap Model. In-depth face-to-face interviews with customer contact staff at two leisure hotels in The Bahamas revealed service quality gaps that stemmed from a limited job enrichment and job rotation for customer contact employees, inaccurate marketing communications, and inadequate resources. Suggestions for closing these gaps are also provided

Overpressuring, diagenesis, and fluid flow at the Matagorda Island 519 field, offshore Texas, Gulf of Mexico

The relations between overpressuring, diagenesis, and fluid flow in sedimentary basins are complex and multifaceted. The Matagorda Island 519 field (MI 519), offshore Texas, provides an excellent area for investigating some of these relations. The top of overpressure at MI 519 occurs at a depth of 3.5 to 3.8 km in a Lower Miocene deltaic sequence. On the basis of log-derived lithostratigraphy, the pressure seal does not appear to be lithologic in origin. Geochemical, mineralogical, and cuttings information indicate instead that the precipitation of diagenetic calcite and possibly quartz cements has been the major factor in seal development. Stratigraphic variation in mudstone chemistry indicates diagenesis has been an open-system process, with significant loss of Ca, Si, Mg, and Fe and gain of K in sediments below the pressure seal. Fluid pressures calculated from shale resistivities provide evidence for several vertically-stacked overpressured compartments at MI 519. Lateral sealing within the overpressured section may be provided by faults and precipitation of diagenetic cements within faults. In contrast to other areas of the Gulf of Mexico Basin, overpressure development at MI 519 does not appear to be due to compaction disequilibrium because of the lack of significant post-Miocene deposition and a lack of a reversal in mudstone porosity below the top of overpressure. More likely causes of overpressuring are clay mineral dewatering, petroleum generation, and the presence of a large column of natural gas. At least six stages of fluid flow and/or diagenetic development have occurred at the field: 1) calcite cementation within preferred intervals from fluids that originated by dissolution of updip salt domes, 2) deep overpressure development and upward focused flow of underlying Mesozoic brines and the development of secondary porosity in reservoir beds by carbonate dissolution, 3) precipitation of a seal by mixing of deeply-sourced and updip-sourced fluids, 4) hydrocarbon generation and shallow overpressure development, with hydrocarbons filling in porosity created by calcite dissolution, 5) “hard” overpressure development from smectite dehydration, and 6) development of a shallow freshwater lens during the Pleistocene lowstand
