Synthesis of Research on Disproportionality in Child Welfare: An Update

Examines the disproportionate representation of minority children in child welfare and summarizes current research findings on racial disparities in treatment and services within the child welfare system

An Analysis of Racial/Ethnic Disproportionality and Disparity at the National, State, and County Levels

Compares data on the involvement of children from five racial/ethnic groups in child protection investigations, substantiated investigations, and placement into foster care. State and county data focus on areas with programs to reduce disproportionality

Role of Ca\u3csup\u3e2+\u3c/sup\u3e in excitation-contraction coupling in echinoderm muscle: comparison with role in other tissues

The longitudinal muscle of the body wall of Isostichopus badionotus may be considered a model for excitation-contraction coupling in echinoderm muscle. Other echinoderm muscles are reviewed by comparison with the model. Echinoderm muscle is also of interest as a model for ‘mutable collagenous tissue’; however, in that tissue, Ca2+ has been proposed to function both in living control systems and in regulation of non-living interstitial substance

Optimization techniques applied to passive measures for in-orbit spacecraft survivability

The purpose of this research is to provide Space Station Freedom protective structures design insight through the coupling of design/material requirements, hypervelocity impact phenomenology, meteoroid and space debris environment sensitivities, optimization techniques and operations research strategies, and mission scenarios. The goals of the research are: (1) to develop a Monte Carlo simulation tool which will provide top level insight for Space Station protective structures designers; (2) to develop advanced shielding concepts relevant to Space Station Freedom using unique multiple bumper approaches; and (3) to investigate projectile shape effects on protective structures design

The Impact of Screening Criteria on Entrepreneurship Research

Entrepreneurship researchers use various types of screening criteria to select samples for study. In that selecting these criteria is, in effect, choosing a definition or model of entrepreneurship, the consequences are immense and have had a direct impact on the generalizability of research and theory development in our field. The purpose of this study is to help entrepreneurship researchers better understand these consequences and, thereby, improve our understanding of entrepreneurial phenomenon. Four of the most commonly used screening criteria are included in this study: firm age, firm size, firm growth, and innovation. Based on a sample of 368 manufacturing firms, the results indicate that few firms fit all or even most of the considered screening criteria and independent-dependent variable relationships vary considerably by screening criteria selection

Estimating Peak Demand for Beach Parking Spaces

The United States Army Corps of Engineers planning guidance stipulates that in order for local beach communities to qualify for Federal cost share funds for Hurricane and Storm Damage Reduction beach renourishment projects, the community must provide public beach access and parking to satisfy peak demand. This study presents a method for estimating peak demand for beach parking spaces in the presence of parking constraints. A Tobit regression model is developed to estimate the number of parking spaces that would be necessary to meet unconstrained demand on a given percentage of peak demand days. For example, the model can be used to estimate the number of parking spaces that would be adequate to meet peak demand on 90% of peak parking days. The Tobit model provides a promising framework for estimating peak parking demand under constrained parking conditions, a situation that characterizes most beach communities.

High Speed Gear Sized and Configured to Reduce Windage Loss

A gear and drive system utilizing the gear include teeth. Each of the teeth has a first side and a second side opposite the first side that extends from a body of the gear. For each tooth of the gear, a first extended portion is attached to the first side of the tooth to divert flow of fluid adjacent to the body of the gear to reduce windage losses that occur when the gear rotates. The gear may be utilized in drive systems that may have high rotational speeds, such as speeds where the tip velocities are greater than or equal to about 68 m/s. Some embodiments of the gear may also utilize teeth that also have second extended portions attached to the second sides of the teeth to divert flow of fluid adjacent to the body of the gear to reduce windage losses that occur when the gear rotates

The Public’s Case Against DTE Energy: Extracting Profits, inducing health harms, and damaging democracy

Together with our partners, MEJC and LittleSis, We The People Michigan finds that DTE has extracted profit from its customers through hundreds of thousands of shutoffs, the second highest amount of rate hikes in the country, and unnecessary power outages that leave customers without power. They have invested heavily in new fossil fuel power plants that place significant health burdens on customers while blocking renewable energy initiatives. Finally, this report digs into the campaign donations of DTE executives, board members, and PAC to reveal how they utilize dark money to advance their profit-driven agenda
