    Are Prize-Linked Savings Accounts the Solution to Arkansas\u27 Savings Problem?

    This research finds that access to prize-linked savings could improve the financial security of Arkansans. Prize-linked savings (PLS) accounts are nontraditional savings products that offer depositors the chance to win cash prizes instead of a typical interest rate return. Given the low median incomes, high liquid asset poverty rates, and high levels of underbanked and undereducated individuals in Arkansas, there is a need for an innovative savings solution like PLS in the state. PLS accounts capitalize on individuals’ propensity for lottery-like risk-taking to inspire the productive behavior of personal saving. A wide range of individuals, especially those who could stand to benefit from PLS instruments the most, find these programs attractive. Various PLS programs have proven successful internationally and within the United States, with clear benefits for both savers and organizing financial institutions. Arkansas banks and credit unions should consider the opportunity presented by PLS programs to grow deposits while providing Arkansas households with an effective, entertaining way to increase personal savings and strengthen their financial situation

    A Case of Arts Coordination in a Rural School District: A Distributed Perspective

    Get PDF
    Though researchers have demonstrated the benefit of prolonged engagement in the arts (Catterall, Dumais, & Hapden-Thompson, 2012) school districts struggle to maintain high quality programs. Rural programs, in particular, are faced with unique challenges to providing arts programs (Donovan & Brown, 2017). Despite these challenges, some rural school districts have succeeded in providing quality programs, which are more in line with more resourced urban districts. Arts researchers (Bodilly, Augustine, & Zakaras, 2008) have found that arts coordination is a strategy to increase access to and the quality of an arts program. Further, districts of quality, even small ones, have arts coordinators (President’s Committee on the Arts and the Humanities and Arts Education Partnership, 1999). Yet, arts coordination is not well defined in the literature and has not been the focus of any rural study. In this research, a single case study was utilized to examine how one rural school district coordinated the leadership of its arts program using distributed leadership. In particular, the research focused on how different levels of leadership from the district to the teachers were involved and the roles they played in arts coordination. The study also examined what impact arts coordination had on the quality of the program and its connection to the community. The results of the study suggest that a rural school district should implement distributed leadership in order to coordinate its arts program and impact its quality and connection to the community. Rural districts should consider a multi-level approach to distributing leadership while considering their own context. This study provides a baseline for further research on rural arts coordination

    An Analysis of the Telegrapher Equation with a Bifurcation Parameter to Model Relativistic Diffusion

    In this paper, we derive a solution to the telegrapher equation. We then apply a bifurcation parameter to the telegrapher equation in order to analyze the behavior of the solution as it changes classification. In order to obtain the solution to both the telegrapher and modified telegrapher equation, we derive the heat equation and telegrapher equation using a continuous random walk. We also solve the heat equation using invariant properties of a particular solution, a random walk analysis, and a Fourier-Laplace transform. The solution to the telegrapher equation contains modified Bessel functions, so we also derive the solutions to both the Bessel and modified Bessel equation. Lastly, we rigorously obtain a solution to the telegrapher equation with an added bifurcation parameter. This solution represents a complete distribution of the solution to the standard telegrapher equation as its solutions transition between classifications

    Macro Self-Portraiture and the Feminine Grotesque

    Get PDF
    According to the Mirriam-Webster online dictionary, “grotesque” is defined as “a style of decorative art characterized by fanciful or fantastic human and animal forms often interwoven with foliage or similar figures that may distort the natural into absurdity, ugliness, or caricature.” Originating from the Old Italian grottesca, cave painting, feminine of grottesco of a cave, from the time of its conception, the grotesque has been inexorably linked to art and the female. The work of other female artists that explore themes of the feminine grotesque are discussed, including Katheryn Wakeman, Jenny Saville, and Maria Lassnig. In my current work, I have been creating oil paintings of macro images of my own body to construct a fragmented and magnified, borderless, grotesque view of the body. The images focus on the mouth, due to its complicated nature as both internal and external, hidden and in plain sight, as well as due to connotations with speech, ingestion, and sexuality. The work walks a fine line between aesthetically pleasing while also commanding an uncomfortably visceral, fleshy quality. While the works are somewhat ambiguous and allow for various readings, they also allude to larger issues of sexism. The use of magnification and fragmentation references the insufficient representation of the female body both art historically —with the beautiful female nude painted by the male artist—as well as contemporarily in an overly-Photoshopped society. The visceral feeling of disgust should allow viewers to commune with their own bodies’ psychophysiological reactions and question the politics of how beauty standards are established as well as whether beauty is a valuable concept when judging the female form

    Cancer phase I trial design using drug combinations when a fraction of dose limiting toxicities is attributable to one or more agents

    Get PDF
    Drug combination trials are increasingly common nowadays in clinical research. However, very few methods have been developed to consider toxicity attributions in the dose escalation process. We are motivated by a trial in which the clinician is able to identify certain toxicities that can be attributed to one of the agents. We present a Bayesian adaptive design in which toxicity attributions are modeled via Copula regression and the maximum tolerated dose (MTD) curve is estimated as a function of model parameters. The dose escalation algorithm uses cohorts of two patients, following the continual reassessment method (CRM) scheme, where at each stage of the trial, we search for the dose of one agent given the current dose of the other agent. The performance of the design is studied by evaluating its operating characteristics when the underlying model is either correctly specified or misspecified. We show that this method can be extended to accommodate discrete dose combinations

    The Effects of Multiple Minimum Wages Throughout the Labor Market

    This paper investigates the effects of legal minimum wages on wages, employment, hours worked and monthly earnings among workers covered by minimum wage legislation as well as those for whom it does not apply (the uncovered sector) in Costa Rica. This country’s large uncovered sector and complex minimum wage policy, which has for decades set numerous wages throughout the wage distribution, provide a stimulating counterpoint to the U.S. framework for the analysis of the impact of minimum wages. We find that legal minimum wages have a significant positive effect on the wages of workers in the covered sector (with an elasticity of 0.10) but no effect on wages of workers in the uncovered sector. We also find that a 10% increase in minimum wages lowers employment in the covered sector by 1.09% and decreases the average number of hours worked of those who remain in the covered sector by about 0.6%. Finally, we show that despite the wide range of minimum wages, the largest impact on the wages and employment of covered sector workers is in the lower half of the distribution.http://deepblue.lib.umich.edu/bitstream/2027.42/40087/3/wp701.pd
