The Early Childhood Educator Preparation Innovation Grant: Lessons from Initial Implementation

The main goals of this implementation study were to: a) examine how the grant recipients were implementing the changes set forth in their grant proposals; b) identify initial barriers to implementation of grant activities; c) identify catalysts that aided in goal attainment and/or partnership development; and d) consider the sustainability of the impact of the grant-related activities. Through structured telephone interviews, we solicited a brief description of major activities associated with the grant; catalysts and/or levers enhancing grant activities; barriers inhibiting implementation of grant activities; and successful strategies utilized to overcome barriers. There was also a specific emphasis on articulation activities within the partnerships, as articulation was considered a foundational component of the EPPI grants.https://spark.siue.edu/ierc_pub/1004/thumbnail.jp

Modulation of Habit Formation by Levodopa in Parkinson's Disease

Dopamine promotes the execution of positively reinforced actions, but its role for the formation of behaviour when feedback is unavailable remains open. To study this issue, the performance of treated/untreated patients with Parkinson's disease and controls was analysed in an implicit learning task, hypothesising dopamine-dependent adherence to hidden task rules. Sixteen patients on/off levodopa and fourteen healthy subjects engaged in a Go/NoGo paradigm comprising four equiprobable stimuli. One of the stimuli was defined as target which was first consistently preceded by one of the three non-target stimuli (conditioning), whereas this coupling was dissolved thereafter (deconditioning). Two task versions were presented: in a ‘Go version’, only the target cue required the execution of a button press, whereas non-target stimuli were not instructive of a response; in a ‘NoGo version’, only the target cue demanded the inhibition of the button press which was demanded upon any non-target stimulus. Levodopa influenced in which task version errors grew from conditioning to deconditioning: in unmedicated patients just as controls errors only rose in the NoGo version with an increase of incorrect responses to target cues. Contrarily, in medicated patients errors went up only in the Go version with an increase of response omissions to target cues. The error increases during deconditioning can be understood as a perpetuation of reaction tendencies acquired during conditioning. The levodopa-mediated modulation of this carry-over effect suggests that dopamine supports habit conditioning under the task demand of response execution, but dampens it when inhibition is required. However, other than in reinforcement learning, supporting dopaminergic actions referred to the most frequent, i. e., non-target behaviour. Since this is passive whenever selective actions are executed against an inactive background, dopaminergic treatment could in according scenarios contribute to passive behaviour in patients with Parkinson's disease

Restructuring Principal Preparation in Illinois: Perspectives on Implementation Successes, Challenges, and Future Outlook

The goals of the current mixed methods study—the Illinois Principal Preparation Implementation Review Project (I-PREP)—are to describe how the new policy is being implemented, learning which aspects of the implementation have been challenging and why they present challenges, and how programs are addressing challenges and realizing improvements in the preparation of their candidates. This report presents findings from the first phase of the study. Results of interviews with program representatives and key Illinois education stakeholders showed the majority of those interviewed support the goals of the new policy and have a positive outlook on its future impact of principal preparation in Illinois. Although some concerns about the implementation were expressed, most believe the redesigned principal preparation programs will ultimately create better prepared school administrators, improved student achievement, and more successful schools. The final report, due in summer 2016, will integrate the findings from this interim report, site visits with selected programs, and a survey with all programs to provide research-based insights in how to improve the policy and its implementation.https://spark.siue.edu/ierc_pub/1003/thumbnail.jp

Navigating the Shift to Intensive Principal Preparation in Illinois: An In-depth Look at Stakeholder Perspectives

The report summarizes findings from a two-year study assessing the progress of these ambitious reforms and describing the changes that occurred as a result of the new policy.https://spark.siue.edu/ierc_pub/1000/thumbnail.jp

Differential Influence of Levodopa on Reward-Based Learning in Parkinson's Disease

The mesocorticolimbic dopamine (DA) system linking the dopaminergic midbrain to the prefrontal cortex and subcortical striatum has been shown to be sensitive to reinforcement in animals and humans. Within this system, coexistent segregated striato-frontal circuits have been linked to different functions. In the present study, we tested patients with Parkinson's disease (PD), a neurodegenerative disorder characterized by dopaminergic cell loss, on two reward-based learning tasks assumed to differentially involve dorsal and ventral striato-frontal circuits. 15 non-depressed and non-demented PD patients on levodopa monotherapy were tested both on and off medication. Levodopa had beneficial effects on the performance on an instrumental learning task with constant stimulus-reward associations, hypothesized to rely on dorsal striato-frontal circuits. In contrast, performance on a reversal learning task with changing reward contingencies, relying on ventral striato-frontal structures, was better in the unmedicated state. These results are in line with the “overdose hypothesis” which assumes detrimental effects of dopaminergic medication on functions relying upon less affected regions in PD. This study demonstrates, in a within-subject design, a double dissociation of dopaminergic medication and performance on two reward-based learning tasks differing in regard to whether reward contingencies are constant or dynamic. There was no evidence for a dose effect of levodopa on reward-based behavior with the patients’ actual levodopa dose being uncorrelated to their performance on the reward-based learning tasks

Institutions for climate change - A method to assess the inherent characteristics of institutions to enable the adaptive capacity of society

This paper addresses the question: How can the inherent characteristics of institutions to stimulate the adaptive capacity of society to climate change from local through to national level be assessed? On the basis of a literature review and several brainstorm sessions, this paper presents six criteria: Variety, learning capacity, space for planned and innovative autonomous action, leadership, availability of resources and fair governance

Substance abuse and intimate partner violence: treatment considerations

Given the increased use of marital- and family-based treatments as part of treatment for alcoholism and other drug disorders, providers are increasingly faced with the challenge of addressing intimate partner violence among their patients and their intimate partners. Yet, effective options for clinicians who confront this issue are extremely limited. While the typical response of providers is to refer these cases to some form of batterers' treatment, three fundamental concerns make this strategy problematic: (1) most of the agencies that provide batterers' treatment only accept individuals who are legally mandated to complete their programs; (2) among programs that do accept nonmandated patients, most substance-abusing patients do not accept such referrals or drop out early in the treatment process; and (3) available evidence suggests these programs may not be effective in reducing intimate partner violence. Given these very significant concerns with the current referral approach, coupled with the high incidence of IPV among individuals entering substance abuse treatment, providers need to develop strategies for addressing IPV that can be incorporated and integrated into their base intervention packages

Spin Structure of the Proton from Polarized Inclusive Deep-Inelastic Muon-Proton Scattering

We have measured the spin-dependent structure function $g_1^p$ in inclusive deep-inelastic scattering of polarized muons off polarized protons, in the kinematic range $0.003 < x < 0.7$ and $1 GeV^2 < Q^2 < 60 GeV^2$. A next-to-leading order QCD analysis is used to evolve the measured $g_1^p(x,Q^2)$ to a fixed $Q^2_0$. The first moment of $g_1^p$ at $Q^2_0 = 10 GeV^2$ is $\Gamma^p = 0.136\pm 0.013(stat.) \pm 0.009(syst.)\pm 0.005(evol.)$. This result is below the prediction of the Ellis-Jaffe sum rule by more than two standard deviations. The singlet axial charge $a_0$ is found to be $0.28 \pm 0.16$. In the Adler-Bardeen factorization scheme, $\Delta g \simeq 2$ is required to bring $\Delta \Sigma$ in agreement with the Quark-Parton Model. A combined analysis of all available proton and deuteron data confirms the Bjorken sum rule.Comment: 33 pages, 22 figures, uses ReVTex and smc.sty. submitted to Physical Review

Large enhancement of deuteron polarization with frequency modulated microwaves

We report a large enhancement of 1.7 in deuteron polarization up to values of 0.6 due to frequency modulation of the polarizing microwaves in a two liters polarized target using the method of dynamic nuclear polarization. This target was used during a deep inelastic polarized muon-deuteron scattering experiment at CERN. Measurements of the electron paramagnetic resonance absorption spectra show that frequency modulation gives rise to additional microwave absorption in the spectral wings. Although these results are not understood theoretically, they may provide a useful testing ground for the deeper understanding of dynamic nuclear polarization.Comment: 10 pages, including the figures coming in uuencoded compressed tar files in poltar.uu, which also brings cernart.sty and crna12.sty files neede
