A Commentary on the WSIPP Report: Evaluating Whether a Risk Assessment Reduced Racial Disparity

The Washington State Institute for Public Policy (WSIPP) recently released a brief report on whether or not implementation of a risk assessment reduced racial disproportionality. This response to the report briefly reviews the findings, critiques the relevance of the research hypotheses, and describes limitations of the research design that undermine the credibility of the conclusions drawn from the study. It also describes a more comprehensive approach to reducing racial disparity and evaluating the success of these efforts

Clostridium difficile

Clostridium difficile (CD) is an infectious disease that has a direct impact on our healthcare resources. “Clostridium difficile, an anaerobic, spore forming, toxin-forming, gram-positive bacillus, has become the leading cause of health care—associated infectious diarrhea (Walters & Zuckerbraun, 2014, p. 329).” I chose this topic because CD is a hypervirulent organism that is not only affecting hospitalized patients but is now emerging as a community acquired infection. Healthcare treatments and costs are on the rise due to persistent and recurrent CD infections. Understanding the pathogenesis, risk factors, diagnostic testing, and management strategies are important in reducing the spread of CD infections (Keske &Letizia 2010)

Software for Estimation of Human Transcriptome Isoform Expression Using RNA-Seq Data

The goal of this thesis research was to develop software to be used with RNA-Seq data for transcriptome quantification that was capable of handling multireads and quantifying isoforms on a more global level. Current software available for these purposes uses various forms of parameter alteration in order to work with multireads. Many still analyze isoforms per gene or per researcher determined clusters as well. By doing so, the effects of multireads are diminished or possibly wrongly represented. To address this issue, two programs, GWIE and ChromIE, were developed based on a simple iterative EM-like algorithm with no parameter manipulation. These programs are used to produce accurate isoform expression levels

Developing the Welfare-to-Work Participation and Employability Appraisal Screening: A Retrospective Study

CalWORKs recipients, unless exempt, are required to participate in welfare-to-work (WTW) program activities as a condition of receiving cash aid. A number of clients, however, may have issues that impede successful engagement in WTW program activities, such as substance abuse, mental health concerns, or domestic violence issues. The Riverside County (California) Department of Mental Health (RCDMH) and the Department of Public Social Services (DPSS) sought to develop a structured case management system to help ensure early identification of WTW customers with barriers to employment and, if necessary, to help facilitate quicker engagement in services to address those barriers and move customers into successful employment. A key component of the structured case management system is an actuarial appraisal screening to help identify those customers most in need of support to make a successful transition to self-sufficiency. This report describes the study conducted by Childrenas Research Center (CRC) to develop an appraisal screening that classifies customers by the likelihood of subsequent WTW program participation and employment. Employment counselors can complete the screening assessment soon after WTW assignment to help identify which customers are in greatest need of additional support and engagement to increase the likelihood of successful program participation

Developing an Actuarial Risk Assessment to Inform the Decisions Made by Adult Protective Service Workers

In 2008, the New Hampshire Department of Health and Human Services Bureau of Elderly and Adult Services (BEAS) and the National Council on Crime and Delinquency (NCCD), with funding provided by the National Institute of Justice (NIJ), collaborated to construct an actuarial risk assessment to classify BEAS clients by their likelihood of elder maltreatment and/or self-neglect in the future. Studies in adult and juvenile corrections and child welfare have demonstrated that active service intervention with high risk clients can reduce criminal recidivism and the recurrence of child maltreatment (Wagner, Hull, & Luttrell, 1995; Eisenberg & Markley, 1987; Baird, Heinz, & Bemus, 1981). The purpose of this research was to examine a large set of individual and referral characteristics, determine their relationship to subsequent elder self-neglect and/or maltreatment, and develop an actuarial risk assessment for BEAS workers to complete at the end of an investigation to inform their case decisions.BEAS and NCCD pursued development of an actuarial risk assessment with the goal of reducing subsequent maltreatment of elderly and vulnerable adults who have been involved in an incident of self-neglect or maltreatment by another person (i.e., abuse, exploitation, or neglect). The actuarial risk assessment described in this report provides BEAS workers with a method to more accurately identify high risk clients and therefore more effectively target service interventions in an effort to protect their most vulnerable clients

Structuring Decisions in Adult Protective Services

A new NCCD Focus article, "Structuring Decisions in Adult Protective Services," describes the value of structured decision frameworks in the growing field of adult protective services (APS). The article highlights findings on risk factors for future adult maltreatment from research literature as well as NCCD's efforts to develop an actuarial-based risk assessment for APS in partnership with the New Hampshire Bureau of Elderly and Adult Services under a grant from the National Institute of Justice

The Effect of Auditory Distractions on Working Memory in People Diagnosed with Attention Deficit Hyperactivity Disorder

This study compared the effect of an auditory distractor on working memory in participants with and without ADHD. Undergraduate students (N-65) were asked to complete a memory task for 25 words in which a pulsating beep sounded from the computer during the middle 5 words. The results indicated that students with ADHD performed significantly worse in the presence of a distraction than those without ADHD. However, the present study also examined the effect of ADHD medication, taken the same day, on working memory. The results indicated that participants with ADHD who had taken medication performed better than those who did not

Diffusive Migration of Low-Mass Proto-planets in Turbulent Disks

Torque fluctuations due to magnetorotational turbulence in proto-planetary disks may greatly influence the migration patterns and survival probabilities of nascent planets. Provided that the turbulence is a stationary stochastic process with finite amplitude and correlation time, the resulting diffusive migration can be described with a Fokker-Planck equation, which we reduce to an advection-diffusion equation. We calibrate the coefficients with existing turbulent-disk simulations and mean-migration estimates, and solve the equation both analytically and numerically. Diffusion tends to dominate over advection for planets of low-mass and those in the outer regions of proto-planetary disks, whether they are described by the Minimum Mass Solar Nebula (MMSN) or by T-Tauri alpha disks. Diffusion systematically reduces the lifetime of most planets, yet it allows a declining fraction of them to survive for extended periods of time at large radii. Mean planet lifetimes can even be formally infinite (e.g. in an infinite steady MMSN), though median lifetimes are always finite. Surviving planets may linger near specific radii where the combined effects of advection and diffusion are minimized, or at large radii, depending on model specifics. The stochastic nature of migration in turbulent disks challenges deterministic planet formation scenarios and suggests instead that a wide variety of planetary outcomes are possible from similar initial conditions. This would contribute to the diversity of (extrasolar) planetary systems.Comment: 31 pages, 7 figures, accepted for publication in Ap

Exploring the Advising Experiences of First Year, First-Generation Community College Students: A Case Study

The current study was conducted to better understand how first-time, full-time, first-generation community college students understand their experiences with academic advising in their first year of college. This study utilized a qualitative research design with a case study methodology to focus on how first-generation students experience academic advising and how their experiences reflect the expectations of their institution. The theoretical framework used for this study was Schlossberg’s Transition Theory. Participants in this study are first-generation community college students and community college academic advisors, and seven first-generation students and two academic advisors participated in individual semi-structured interviews. Data collected also includes documents related to academic advising produced by the institution. This study\u27s findings reveal connections and disconnections across the student experience and the institutional expectations, as well as significant elements of the first-generation transition into college. Although the role of academic guidance in advising is aligned across all data sources, the findings from this study indicate that first-generation students are also looking to academic advisors for emotional support and additional access to knowledge and resources. Findings from this study reveal that academic advisors are aware of these needs. Still, their preparation and training lack depth, and recommendations include more intentional, ongoing training for academic advisors. Suggestions for future research involve increasing the population size and scope. Further exploration of the impact of gender identity in academic advising is also recommended

Investigating motor training in people who stutter using fNIRs

This pilot study investigated motor learning and neuroplasticity in persons who do and do not stutter before and after participation in a phonation onset training protocol. Outcomes included phonation onset time and percent change in oxygenation level of hemoglobin using fNIRS in prescribed brain areas as a result of training. The authors hypothesized that people who stutter (PWS) would 1) exhibit a breakdown in auditory perception to motor production interactions, 2) demonstrate a difference in the way in which they perceive and learn motor information compared to someone who does not stutter (nPWS), and 3) exhibit reduced brain activity correlations between brain regions involved in perceived auditory targets and those involved in automatic motor production. 4 PWS and 4 nPWS between the ages of 20 to 59 participated in the study. There were no statistically significant between-group interactions, although there was a statistically significant within-subject change for production of breathy onset after training. Perception testing resulted in a ceiling effect, which must be addressed before further investigation. Observations were made utilizing graphed fNIRS data, which suggested right-sided auditory overactivation and left-sided suppression in PWS, as was hypothesized. The findings from the present pilot study serve as a cause for further investigation to either confirm or deny hemodynamic trends observed between PWS and nPWS
