Implementing a case management initiative in high-need schools

States continue to experiment with ways of improving health and human service use by people with complex needs. Such efforts have often sought to increase individual and family control over services as well as to enhance coordination among providers. Paths to achieving these goals are not well understood. This study draws on two previously distinct conceptual frameworks to examine how 71 public schools implemented a team approach to increasing family and agency engagement for children at risk. Results from longitudinal data fit the core components expected to affect implementation and also indicated sustainability, but in ways distinctive to the initiative's public school settings. Accountability to the state appeared to be a major catalyst, yet in some respects also constrained local agencies from participating as intended. School inertia may have both undermined the program through some evaluation practices and gaps in administrative support, and supported integration into organizational routines and successful experimentation over time in increasing caregiver involvement. Family hesitation about sharing information with multiple agencies may also help explain why the goal of seamless coordination remains elusive

John H. Steele, 1926–2013

This special issue of Oceanography is dedicated to the memory of John H. Steele, who passed away on November 4, 2013, at the age of 86. John was a seminal figure in the creation of the US Global Ocean Ecosystem Dynamics (GLOBEC) and International GLOBEC programs, and remained involved in them through his scientific endeavors and program leadership. We benefitted from his keen intellect, wide-ranging knowledge, deep insight, and unfailing good humor and gentlemanly manner

Analysis of element yield, bacterial community structure and the impact of carbon sources for bioleaching rare earth elements from high grade monazite

Rare earth element (REE) recovery from waste streams, mine tailings or recyclable components using bioleaching is gaining traction due to the shortage and security of REE supply as well as the environmental problems that occur from processing and refining. Four heterotrophic microbial species with known phosphate solubilizing capabilities were evaluated for their ability to leach REE from a high-grade monazite when provided with either galactose, fructose or maltose. Supplying fructose resulted in the greatest amount of REE leached from the ore due to the largest amount of organic acid produced. Gluconic acid was the dominant organic acid identified produced by the cultures, followed by acetic acid. The monazite proved difficult to leach with the different carbon sources, with preferential release of Ce over La, Nd and Pr

Detrital zircon provenance and lithofacies associations of montmorillonitic sands in the maastrichtian ripley formation: Implications for mississippi embayment paleodrainage patterns and paleogeography

© 2020 by the authors. Licensee MDPI, Basel, Switzerland. We provide new detrital zircon evidence to support a Maastrichtian age for the establishment of the present-day Mississippi River drainage system. Fieldwork conducted in Pontotoc County, Mississippi, targeted two sites containing montmorillonitic sand in the Maastrichtian Ripley Formation. U-Pb detrital zircon (DZ) ages from these sands (n = 649) ranged from Mesoarchean (~2870 Ma) to Pennsylvanian (~305 Ma) and contained ~91% Appalachian-derived grains, including Appalachian–Ouachita, Gondwanan Terranes, and Grenville source terranes. Other minor source regions include the Mid-Continent Granite–Rhyolite Province, Yavapai–Mazatzal, Trans-Hudson/Penokean, and Superior. This indicates that sediment sourced from the Appalachian Foreland Basin (with very minor input from a northern or northwestern source) was being routed through the Mississippi Embayment (MSE) in the Maastrichtian. We recognize six lithofacies in the field areas interpreted as barrier island to shelf environments. Statistically significant differences between DZ populations and clay mineralogy from both sites indicate that two distinct fluvial systems emptied into a shared back-barrier setting, which experienced volcanic ash input. The stratigraphic positions of the montmorillonitic sands suggest that these deposits represent some of the youngest Late Cretaceous volcanism in the MSE

The effects of participation level on recidivism: a study of drug treatment courts using propensity score matching

Abstract Background: Empirical evidence has suggested that drug treatment courts (DTCs) reduce re-arrest rates. However, DTC program completion rates are low and little is known about the effectiveness of lower levels of program participation. Objectives: We examined how DTC program referral, enrollment without completion, and completion, affected re-arrest rates during a two-year follow-up. Research design: We used statewide North Carolina data from criminal courts merged with DTC data. Propensity score matching was used to select comparison groups based on demographic characteristics, criminal histories, and drug of choice (when available). Average treatment effects on the treated were computed. Measures: DTC participation levels included referral without enrollment, (n = 2,174), enrollment without completion (n = 954), and completion (n = 747). Recidivism measured as re-arrest on a substance-related charge, on a violent offense charge not involving an allegation of substance abuse, and on any charge (excluding infractions) was examined by felony and misdemeanor status during a two-year follow-up period

A Cdx4-Sall4 Regulatory Module Controls the Transition from Mesoderm Formation to Embryonic Hematopoiesis

Summary Deletion of caudal/cdx genes alters hox gene expression and causes defects in posterior tissues and hematopoiesis. Yet, the defects in hox gene expression only partially explain these phenotypes. To gain deeper insight into Cdx4 function, we performed chromatin immunoprecipitation sequencing (ChIP-seq) combined with gene-expression profiling in zebrafish, and identified the transcription factor spalt-like 4 (sall4) as a Cdx4 target. ChIP-seq revealed that Sall4 bound to its own gene locus and the cdx4 locus. Expression profiling showed that Cdx4 and Sall4 coregulate genes that initiate hematopoiesis, such as hox, scl, and lmo2. Combined cdx4/sall4 gene knockdown impaired erythropoiesis, and overexpression of the Cdx4 and Sall4 target genes scl and lmo2 together rescued the erythroid program. These findings suggest that auto- and cross-regulation of Cdx4 and Sall4 establish a stable molecular circuit in the mesoderm that facilitates the activation of the blood-specific program as development proceeds
