IDEA Requirements for Use of PBS: Guidelines for Responsible Agencies

Positive behavioral interventions and supports (PBS) is the federal law's preferred strategy for dealing with challenging behaviors of students with disabilities. The Individuals with Disabilities Education Act (IDEA) requires PBS to be considered in all cases of students whose behavior impedes their learning or the learning of others, reflecting IDEA's preference for use of state-of-the-art technology in special education. This article explains the legal ramifications of these requirements for responsible agencies, including schools, school boards, other local educational agencies, and state educational agencies

Matrix of Federal Statutes and Federal and State Court Decisions Reflecting the Core Concepts of Disability Policy

This article sets out the 18 core concepts of policy affecting families who have children with disabilities. It defines each concept, provides a reference to the constitutional principle(s) that undergird the core concept, cites the federal statutes that reflect the core concept, and references the decisions of the United States Supreme Court and other courts interpreting or defining the core concept

Public Policy Foundations for Positive Behavioral Interventions, Strategies, and Supports

This article examines precedents that justify Congress in creating a preference for positive behavioral interventions, strategies, and supports over other interventions in the 1997 Amendments to the Individuals with Disabilities Education Act (IDEA). The authors concluded that the IDEA 1997 provisions are warranted by several well-established precedents based in constitutional law, in the right to treatment and the right to education cases, in moral philosophy, and in democratic-government philosophy

Unhealthy Drinking Patterns in Older Adults: Prevalence and Associated Characteristics

To examine the prevalence of unhealthy drinking patterns in community-dwelling older adults and its association with sociodemographic and health characteristics. DESIGN : Cross-sectional analysis of nationally representative survey data. SETTING : The data source was the 2003 Access to Care file of the Medicare Current Beneficiary Survey, which represents the continuously enrolled Medicare population. PARTICIPANTS : Community-dwelling Medicare beneficiaries aged 65 and older (N=12,413). MEASUREMENTS : The prevalence of unhealthy alcohol use by older adults defined in relation to two parameters of recommended limits: monthly use exceeding 30 drinks per typical month and “heavy episodic” drinking of four or more drinks in any single day during a typical month in the previous year. Sociodemographic and health status variables were also included. RESULTS : Nine percent of elderly Medicare beneficiaries reported unhealthy drinking, with higher prevalence in men (16%) than women (4%). In logistic regression analyses with the full sample, higher education and income; better health status; male sex; younger age; smoking; being white; and being divorced, separated, or single were associated with higher likelihood of unhealthy drinking. Among drinkers, in addition to sociodemographic variables, self-reported depressive symptoms were positively associated with unhealthy drinking. Among unhealthy drinkers, race and ethnicity variables were associated with likelihood of heavy episodic drinking. CONCLUSION : Almost one in 10 elderly Medicare beneficiaries report exceeding recommended drinking limits. Several distinct unhealthy drinking patterns were identified and associated with sociodemographic and health characteristics, suggesting the value of additional targeted approaches within the context of universal screening to reduce alcohol misuse by older adults.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/65179/1/j.1532-5415.2007.01539.x.pd

Grieving, Valuing, and Viewing Differently: The Global War on Terror's American Toll

In March 2003 (the eve of Iraq’s invasion) the George W. Bush Administration reissued, extended, and enforced a Directive prohibiting the publication and broadcast of images and videos capturing the ritual repatriation of America’s war dead. This Directive (known as the Dover Ban) is exemplary of a wider set of more subtle processes and practices of American statecraft working to move suffering and dead American soldiers out of the American public eye’s sight. This is due, I argue, to dominant (Government and Military) bodies knowing, valuing, and counting generic soldier material as but a “precious resource” with which to fuel the GWoT. However, my investigation into the (in)visibility of suffering and dead American soldiers since 9/11 reveals that subordinate yet challenging American bodies could not be stopped from knowing, valuing, and counting American soldiers differently—in life, injury, and death. Indeed, regarding American soldiers as grievable persons, the challenging actions discussed in this article demonstrate how Americans were moved to demand and take the right to count and account for soldiers’ suffering and deaths in public and the very face of dominant bodies that “don’t do body counts”

Female Genitalia Concealment Promotes Intimate Male Courtship in a Water Strider

Violent coercive mating initiation is typical for animals with sexual conflict over mating. In these species, the coevolutionary arms-race between female defenses against coercive mating and male counter-adaptations for increased mating success leads to coevolutionary chases of male and female traits that influence the mating. It has been controversial whether one of the sexes can evolve traits that allow them to “win” this arms race. Here, we use morphological analysis (traditional and scanning electron micrographs), laboratory experiments and comparative methods to show how females of a species characterized by typical coercive mating initiation appear to “win” a particular stage of the sexual conflict by evolving morphology to hide their genitalia from direct, forceful access by males. In an apparent response to the female morphological adaptation, males of this species added to their typically violent coercive mounting of the female new post-mounting, pre-copulatory courtship signals produced by tapping the water's surface with the mid-legs. These courtship signals are intimate in the sense that they are aimed at the female, on whom the male is already mounted. Females respond to the signals by exposing their hidden genitalia for copulatory intromission. Our results indicate that the apparent victory of coevolutionary arms race by one sex in terms of morphology may trigger evolution of a behavioral phenotype in the opposite sex

A latent trait look at pretest-posttest validation of criterion-referenced test items

Since Cox and Vargas (1966) introduced their pretest-posttest validity index for criterion-referenced test items, a great number of additions and modifications have followed. All are based on the idea of gain scoring; that is, they are computed from the differences between proportions of pretest and posttest item responses. Although the method is simple and generally considered as the prototype of criterion-referenced item analysis, it has many and serious disadvantages. Some of these go back to the fact that it leads to indices based on a dual test administration- and population-dependent item p values. Others have to do with the global information about the discriminating power that these indices provide, the implicit weighting they suppose, and the meaningless maximization of posttest scores they lead to. Analyzing the pretest-posttest method from a latent trait point of view, it is proposed to replace indices like Cox and Vargas’ Dpp by an evaluation of the item information function for the mastery score. An empirical study was conducted to compare the differences in item selection between both methods

Numerical analysis of hydraulic jumps using OpenFOAM

[EN] The present paper deals with a hydraulic jump study, characterization and numerical modeling. Hydraulic jumps constitute a common phenomenon in the hydraulics of open channels that increases the shear stress on streambeds, so promoting their erosion. A three-dimensional computational fluid dynamics model is proposed to analyze hydraulic jumps in horizontal smooth rectangular prismatic open-air channels (i.e., the so-called classical hydraulic jump). Turbulence is modeled using three widely used Reynolds-averaged Navier Stokes (RANS) models, namely: Standard k ε, RNG k ε, and SST k ω. The coexistence of two fluids and the definition of an interface between them are treated using a volume method in Cartesian grids of several element sizes. An innovative way to deal with the outlet boundary condition that allows the size of the simulated domain to be reduced is presented. A case study is conducted for validation purposes (FR1 ∼ 6.10, Re1 ∼ 3.5·105): several variables of interest are computed (sequent depths, efficiency, roller length, free surface profile, etc.) and compared to previous studies, achieving accuracies above 98% in all cases. In the light of the results, the model can be applied to real-life cases of design of hydraulic structures.This research was conducted thanks to the funding provided by the VALi + D R&D Program of the Generalitat Valenciana (Spain).
