Emotional, Psychological, and Behavioral Challenges of Children with Incarcerated Parents

Children of incarcerated mothers and fathers are at a high risk of developing emotion­al, psychological, and behavioral problems (Dallaire, 2000; Lotze, Ravindran, & Myers, 2010; Nurse, 2004). The literature review conducted for this study noted several problem­atic behaviors. Some children were at a high risk for delinquency and criminal activity. Others experienced several home displacements which led to foster care or grand parenting responsibilities (Belknap, 2006). Further, mental health issues and school behavior prob­lems were directly linked to parental incarceration (Arditti, 2012). Four main problems in children were identified, which included aggression, anxiety, poor concentration, and so­cial withdrawal. Some children of incarcerated parents demonstrated destructive attributes such as depression, predictive behaviors related to unsuccessful school achievement, and greater risk for intergenerational incarceration (Wildeman, 2010)

A Deductive, Participative, And Iterative Process: A Case Study In Curricular Review

This paper focuses on a deductive, participative, and iterative process for curricular revision at a public Midwestern university in the Merchandising and Fashion Design program. A systematic, nonlinear, organized process is presented and details specific components used in curricular review. The guiding framework for the redesign was that of Garner and Buckley (1988). That is, feedback was solicited and incorporated from educators, students, and employers. In each of the two-year process, the program was viewed as a whole, with input from faculty at every step, and also viewed from a micro-perspective by examining each course individually. The process included peer review, with each faculty member encouraged to review not only their own courses, but those of their colleagues as well. At times, the curricular review process seemed overwhelming with the significant amount of data and resource constraints to consider. The systematic process presented assisted in managing multiple considerations and constituents involved in the curriculum review. Besides maintaining a relevant and current curriculum, the process provided a multitude of benefits for the department. Significant changes were made to the curriculum, but more honest relationships were reestablished and an increased understanding among colleagues was an unexpected benefit of the lengthy, but necessary, examination of the program and resulting curricular changes in the department

Effect of Carbon Dioxide on the Twinkling Artifact in Ultrasound Imaging of Kidney Stones: A Pilot Study

Bone demineralization, dehydration and stasis put astronauts at increased risk of forming kidney stones in space. The color-Doppler ultrasound "twinkling artifact," which highlights kidney stones with color, can make stones readily detectable with ultrasound; however, our previous results suggest twinkling is caused by microbubbles on the stone surface which could be affected by the elevated levels of carbon dioxide found on space vehicles. Four pigs were implanted with kidney stones and imaged with ultrasound while the anesthetic carrier gas oscillated between oxygen and air containing 0.8% carbon dioxide. On exposure of the pigs to 0.8% carbon dioxide, twinkling was significantly reduced after 9-25 min and recovered when the carrier gas returned to oxygen. These trends repeated when pigs were again exposed to 0.8% carbon dioxide followed by oxygen. The reduction of twinkling caused by exposure to elevated carbon dioxide may make kidney stone detection with twinkling difficult in current space vehicles

Medical Students and Pandemic Influenza

To assess knowledge of pandemic influenza, we administered a questionnaire to all medical students at the University of Alberta; 354 (69%) of 510 students responded. Data from questionnaires such as this could help determine the role of medical students during a public health emergency

Person-Centered Practice as Anchor and Beacon: Pandemic Wisdom from the NCAPPS Community

Objective: This article summarizes the individual, systemic, and collective challenges and opportunities presented by the COVID-19 pandemic, based on 16 videos solicited by the National Center on Advancing Person-Centered Practices and Systems (NCAPPS) and submitted by NCAPPS collaborators during the first six months of the pandemic. Method: Informed by participatory action approaches and content analysis, we describe common themes in a series of 16 videos solicited by NCAPPS from subject matter experts with professional and lived experience of disability and human services systems. Results: The team organized the findings to identify both specific factors within each of the levels and the complex interplay between each of the factors at four levels: (1) individual disabled people and their/our spouses, family, and friends; (2) person-centered strategies; (3) system, services, and providers; and (4) society. Discussion: Practices such as person-centered planning, peer support, and self-direction enable us to respond to and cope with the traumas caused by the pandemic. Systems-level themes reveal clear opportunities for abandoning outdated practices and rebuilding the service system in a more person-centered manner. Commentators argued that a society that strives for collective responsibility and well-being and leaves no one behind will generate the interdependence necessary to weather disasters like the COVID-19 pandemic. Conclusion: Person-centered practices are both an anchor for weathering the pandemic and a beacon for rebuilding lives, service systems, and communities

On Machine-Learned Classification of Variable Stars with Sparse and Noisy Time-Series Data

With the coming data deluge from synoptic surveys, there is a growing need for frameworks that can quickly and automatically produce calibrated classification probabilities for newly-observed variables based on a small number of time-series measurements. In this paper, we introduce a methodology for variable-star classification, drawing from modern machine-learning techniques. We describe how to homogenize the information gleaned from light curves by selection and computation of real-numbered metrics ("feature"), detail methods to robustly estimate periodic light-curve features, introduce tree-ensemble methods for accurate variable star classification, and show how to rigorously evaluate the classification results using cross validation. On a 25-class data set of 1542 well-studied variable stars, we achieve a 22.8% overall classification error using the random forest classifier; this represents a 24% improvement over the best previous classifier on these data. This methodology is effective for identifying samples of specific science classes: for pulsational variables used in Milky Way tomography we obtain a discovery efficiency of 98.2% and for eclipsing systems we find an efficiency of 99.1%, both at 95% purity. We show that the random forest (RF) classifier is superior to other machine-learned methods in terms of accuracy, speed, and relative immunity to features with no useful class information; the RF classifier can also be used to estimate the importance of each feature in classification. Additionally, we present the first astronomical use of hierarchical classification methods to incorporate a known class taxonomy in the classifier, which further reduces the catastrophic error rate to 7.8%. Excluding low-amplitude sources, our overall error rate improves to 14%, with a catastrophic error rate of 3.5%.Comment: 23 pages, 9 figure

An in vivo demonstration of efficacy and acute safety of burst wave lithotripsy using a porcine model

Burst wave lithotripsy (BWL) is a new non-invasive method for stone comminution using bursts of sub-megahertz ultrasound. A porcine model of urolithiasis and techniques to implement BWL treatment has been developed to evaluate its effectiveness and acute safety. Six human calcium oxalate monohydrate stones (6–7 mm) were hydrated, weighed, and surgically implanted into the kidneys of three pigs. Transcutaneous stone treatments were performed with a BWL transducer coupled to the skin via an external water bath. Stone targeting and treatment monitoring were performed with a co-aligned ultrasound imaging probe. Treatment exposures were applied in three 10-minute intervals for each stone. If sustained cavitation in the parenchyma was observed by ultrasound imaging feedback, treatment was paused and the pressure amplitude was decreased for the remaining time. Peak negative focal pressures between 6.5 and 7 MPa were applied for all treatments. After treatment, stone fragments were removed from the kidneys. At least 50% of each stone was reduced to <2 mm fragments. 100% of four stones were reduced to <4 mm fragments. Magnetic resonance imaging showed minimal injury to the functional renal volume. This study demonstrated that BWL could be used to effectively fragment kidney stones with minimal injury

Aerocapture Systems Analysis for a Titan Mission

Performance projections for aerocapture show a vehicle mass savings of between 40 and 80%, dependent on destination, for an aerocapture vehicle compared to an all-propulsive chemical vehicle. In addition aerocapture is applicable to multiple planetary exploration destinations of interest to NASA. The 2001 NASA In-Space Propulsion Program (ISP) technology prioritization effort identified aerocapture as one of the top three propulsion technologies for solar system exploration missions. An additional finding was that aerocapture needed a better system definition and that supporting technology gaps needed to be identified. Consequently, the ISP program sponsored an aerocapture systems analysis effort that was completed in 2002. The focus of the effort was on aerocapture at Titan with a rigid aeroshell system. Titan was selected as the initial destination for the study due to potential interest in a follow-on mission to Cassini/Huygens. Aerocapture is feasible, and the performance is adequate, for the Titan mission and it can deliver 2.4 times more mass to Titan than an all-propulsive system for the same launch vehicle

Aerocapture Systems Analysis for a Neptune Mission

A Systems Analysis was completed to determine the feasibility, benefit and risk of an aeroshell aerocapture system for Neptune and to identify technology gaps and technology performance goals. The systems analysis includes the following disciplines: science; mission design; aeroshell configuration; interplanetary navigation analyses; atmosphere modeling; computational fluid dynamics for aerodynamic performance and aeroheating environment; stability analyses; guidance development; atmospheric flight simulation; thermal protection system design; mass properties; structures; spacecraft design and packaging; and mass sensitivities. Results show that aerocapture is feasible and performance is adequate for the Neptune mission. Aerocapture can deliver 1.4 times more mass to Neptune orbit than an all-propulsive system for the same launch vehicle and results in a 3-4 year reduction in trip time compared to all-propulsive systems. Enabling technologies for this mission include TPS manufacturing; and aerothermodynamic methods for determining coupled 3-D convection, radiation and ablation aeroheating rates and loads
