Progressive = Permissive? Not According to John Dewey…Subjects Matter!

The progressive education movement, which promoted the philosophy of school reform that prevailed among waves of educational innovators throughout the 20th century, has been associated historically with John Dewey and has prided itself on implementing his ‘childcentered’ principles. However, there were major differences between many of the progressives’ attitudes and Dewey’s ideas about learning. To better understand why issues that originally separated Dewey from other progressives continue to be a source of conflict and confusion even today, as exemplified by an article that appeared in an edition of Education Week (Spencer, 2001; Weiner, 2001), this paper examines the philosophy and practices of some significant early progressive thinkers in light of Dewey’s theory of experience

Readiness for Discharge in Parents of Hospitalized Children

Parental preparation for a child\u27s discharge from the hospital sets the stage for successful transitioning to care and recovery at home. In this study of 135 parents of hospitalized children, the quality of discharge teaching, particularly the nurses\u27 skills in “delivery” of parent teaching, was associated with increased parental readiness for discharge, which was associated with less coping difficulty during the first 3 weeks postdischarge. Parental coping difficulty was predictive of greater utilization of posthospitalization health services. These results validate the role of the skilled nurse as a teacher in promoting positive outcomes at discharge and beyond the hospitalization

Evaluation of stratospheric age of air from CF4, C2F6, C3F8, CHF3, HFC-125, HFC-227ea and SF6; implications for the calculations of halocarbon lifetimes, fractional release factors and ozone depletion potentials

In a changing climate, potential stratospheric circulation changes require long-term monitoring. Stratospheric trace gas measurements are often used as a proxy for stratospheric circulation changes via the <q>mean age of air</q> values derived from them. In this study, we investigated five potential age of air tracers – the perfluorocarbons CF₄, C₂F₆ and C₃F₈ and the hydrofluorocarbons CHF₃ (HFC-23) and HFC-125 – and compare them to the traditional tracer SF₆ and a (relatively) shorter-lived species, HFC-227ea. A detailed uncertainty analysis was performed on mean ages derived from these <q>new</q> tracers to allow us to confidently compare their efficacy as age tracers to the existing tracer, SF₆. Our results showed that uncertainties associated with the mean age derived from these new age tracers are similar to those derived from SF₆, suggesting that these alternative compounds are suitable in this respect for use as age tracers. Independent verification of the suitability of these age tracers is provided by a comparison between samples analysed at the University of East Anglia and the Scripps Institution of Oceanography. All five tracers give younger mean ages than SF₆, a discrepancy that increases with increasing mean age. Our findings qualitatively support recent work that suggests that the stratospheric lifetime of SF₆ is significantly less than the previous estimate of 3200 years. The impact of these younger mean ages on three policy-relevant parameters – stratospheric lifetimes, fractional release factors (FRFs) and ozone depletion potentials – is investigated in combination with a recently improved methodology to calculate FRFs. Updates to previous estimations for these parameters are provided

Effectiveness of a Cognitive Behavioral Weight Management Intervention in Obese Patients with Psychotic Disorders Compared to Patients with Non-Psychotic Disorders or No Psychiatric Disorders: Results from a 12-month, Real-World Study

Objective—Studies of behavioral weight loss intervention in psychotic patients are sparse and its efficacy compared to other obese patients is unknown. Therefore, we compared the effect of a cognitive-behavioral weight loss intervention in obese subjects with psychotic disorders, other psychiatric diagnoses and without psychiatric disorders. Methods—12-month, naturalistic study of weekly group or individual cognitive-behavioral weight management in 222 consecutively enrolled obese patients (body mass index (BMI): 43.7±9.6) with psychotic-spectrum disorders (PSD, n=47), other psychiatric disorders (OPD, n=49) and no psychiatric disorder (NPD, n=126). Results—PSD patients had greater treatment persistence (48.9%) and longer treatment duration (8.7±4.4 months) than OPD (22.4%, 5.4±4.3 months) and NPD (22.2%, 4.9±4.7 months) patients (p’s\u3c.01, number-needed-to-treat (NNT)=3). In last-observation-carried-forward analyses, PSD patients had greater percent baseline weight loss at 12 months (5.1±9.3%) than OPD and NPD patients (2.7±5.5% and 2.4±6.3%); greater percent BMI loss at 9 and 12 months than both groups (p’s\u3c.05), and greater BMI loss at 9 months (2.1±3.5) and 12 months (2.3±4.1) than NPD patients (1.1±2.3 and 1.2±2.4). Furthermore, weight loss ≥5%, occurred in 42.6% of PSD patients vs. 18.4% and 23.0% in OPD and NPD patients (p’s\u3c.01, NNT=5 and 6). The strongest weight loss predictor was treatment duration (β=.51–.54, p\u3c.001). Attrition was predicted by NPD (p=.001) and OPD group status (p=.036), lower proportion of group sessions (p=.002), higher depression (p=.028), and lower baseline BMI (p=0.030). Conclusions—Psychosis-spectrum disorder patients had greater weight loss than other obese patients. Non-adherence and depression should be targeted to enhance weight loss success

Creating and evaluating genetic tests predictive of drug response

A key goal of pharmacogenetics — the use of genetic variation to elucidate inter-individual variation in drug treatment response — is to aid the development of predictive genetic tests that could maximize drug efficacy and minimize drug toxicity. The completion of the Human Genome Project and the associated HapMap Project, together with advances in technologies for investigating genetic variation, have greatly advanced the potential to develop such tests; however, many challenges remain. With the aim of helping to address some of these challenges, this article discusses the steps that are involved in the development of predictive tests for drug treatment response based on genetic variation, and factors that influence the development and performance of these tests

The state of pediatric asthma in Chicago's Humboldt Park: a community-based study in two local elementary schools

Abstract Background Pediatric asthma is a serious public health problem in Chicago and has been designated a high priority concern by residents of Chicago's Humboldt Park, a diverse community area with a large number of Puerto Rican, African American, and Mexican American families. Methods In May 2009, following the principles of community-based participatory research, a cross-sectional asthma screening survey was administered to adult caregivers of children attending two Humboldt Park elementary schools. Data were analyzed to determine the prevalence of diagnosed and probable asthma as well as the degree of asthma control among affected children; associations between asthma outcomes and mutable triggers were evaluated. Results Surveys from 494 children were evaluated. Physician-diagnosed asthma was reported for 24.9% of children and probable asthma identified in an additional 16.2% of children. Asthma was poorly or moderately controlled in 60.0% of diagnosed children. Smoking occurred inside 25.0% of households and 75.0% of caregivers reported idling of vehicles in their community. Report of general stress among caregivers, stress due to community crime, and/or an inability to cope with everyday life were significantly and positively associated with poor asthma morbidity and control among affected children. Conclusions Despite high prevalence rates and poor asthma morbidity and control in Humboldt Park, the association of these measures with mutable variables is promising. A community-based asthma intervention to address the issues identified in this study is needed to affect positive change.http://deepblue.lib.umich.edu/bitstream/2027.42/112574/1/12887_2010_Article_357.pd

Interpersonal neural synchrony and mental disorders: unlocking potential pathways for clinical interventions

Introduction: Interpersonal synchronization involves the alignment of behavioral, affective, physiological, and brain states during social interactions. It facilitates empathy, emotion regulation, and prosocial commitment. Mental disorders characterized by social interaction dysfunction, such as Autism Spectrum Disorder (ASD), Reactive Attachment Disorder (RAD), and Social Anxiety Disorder (SAD), often exhibit atypical synchronization with others across multiple levels. With the introduction of the “second-person” neuroscience perspective, our understanding of interpersonal neural synchronization (INS) has improved, however, so far, it has hardly impacted the development of novel therapeutic interventions. Methods: To evaluate the potential of INS-based treatments for mental disorders, we performed two systematic literature searches identifying studies that directly target INS through neurofeedback (12 publications; 9 independent studies) or brain stimulation techniques (7 studies), following PRISMA guidelines. In addition, we narratively review indirect INS manipulations through behavioral, biofeedback, or hormonal interventions. We discuss the potential of such treatments for ASD, RAD, and SAD and using a systematic database search assess the acceptability of neurofeedback (4 studies) and neurostimulation (4 studies) in patients with social dysfunction. Results: Although behavioral approaches, such as engaging in eye contact or cooperative actions, have been shown to be associated with increased INS, little is known about potential long-term consequences of such interventions. Few proof-of-concept studies have utilized brain stimulation techniques, like transcranial direct current stimulation or INS-based neurofeedback, showing feasibility and preliminary evidence that such interventions can boost behavioral synchrony and social connectedness. Yet, optimal brain stimulation protocols and neurofeedback parameters are still undefined. For ASD, RAD, or SAD, so far no randomized controlled trial has proven the efficacy of direct INS-based intervention techniques, although in general brain stimulation and neurofeedback methods seem to be well accepted in these patient groups. Discussion: Significant work remains to translate INS-based manipulations into effective treatments for social interaction disorders. Future research should focus on mechanistic insights into INS, technological advancements, and rigorous design standards. Furthermore, it will be key to compare interventions directly targeting INS to those targeting other modalities of synchrony as well as to define optimal target dyads and target synchrony states in clinical interventions
