The making of a liberal education: Political economy of Austrian school reform, 1865 - 1875
The rise of mass schooling is an important contributor to modern economic growth. But its form, content, scale and manner of provision are all matters of public policy that are subject to politics. The rise of modern schooling is frequently cast as a product of broadened suffrage and stronger political voice of the masses, which overcame the political opposition from old ruling elites. We investigate this hypothesis, using the case of a school reform undertaken in Imperial Austria in 1869. We show that while landowners were less likely to vote for school modernization than urban and business interests, the strongest opposition came from the rural areas where the suffrage was in fact most numerous. The reform passed in spite of their opposition but, interestingly, post-reform developments suggest that passive resistance to it continued in the countryside in spite of the alleged benefits that education was billed to bring the masses
Pathologies of the Poor: What do the War on Drugs and Welfare Reform Have in Common?
The Personal Responsibility and Work Opportunity Reconciliation Act of 1996 (PRWORA) authorized drug testing of welfare recipients as a criterion for assistance eligibility. This raises the question of a possible confluence of War on Drugs and Welfare Reform policies, as indicated by continuity in policymakersā rhetoric. We examine federal-level policymakersā debates surrounding the authorization of drug testing welfare recipients. The analysis reveals that themes of social pathology were present in both policy areas. Crime, drug addiction, welfare dependency, and drug testing themes are comparable in both debates. Teen pregnancy, out-of-wedlock birth, and female-headed households themes were more prevalent in Welfare Reform debates, with the exception of drug-addicted newborns, which crossed both policy streams
The rise of public schooling in nineteenthācentury Imperial Austria: Who gained and who paid?
The rise of education features prominently in the debate on the sources of modern economic growth. Existing accounts stress the importance of popular demand for its public provision. We argue that such an explanation for the spread of schooling is a poor fit for many nationsā schooling histories, such as Imperial Austria. We show that in the Austrian case, schooling and economic development had limited impact on each other; that the popular demand for schooling was weak and that the push for school expansion came mainly from the top of the political hierarchy
Delta-9-tetrahydrocannabinol protects against MPP+ toxicity in SH-SY5Y cells by restoring proteins involved in mitochondrial biogenesis
This project was supported through a studentship awarded by the Plymouth University Peninsula Schools of Medicine and Dentistry.Proliferator-activated receptor Ī³ (PPARĪ³) activation can result in transcription of proteins involved in oxidative stress defence and mitochondrial biogenesis which could rescue mitochondrial dysfunction in Parkinson's disease (PD).The PPARĪ³ agonist pioglitazone is protective in models of PD; however side effects have limited its clinical use. The cannabinoid Ī9-tetrahydrocannabinol (Ī9-THC) may have PPARĪ³ dependent anti-oxidant properties. Here we investigate the effects of Ī9-THC and pioglitazone on mitochondrial biogenesis and oxidative stress. Differentiated SH-SY5Y neuroblastoma cells were exposed to the PD relevant mitochondrial complex 1 inhibitor 1-methyl- 4-phenylpyridinium iodide (MPP+). We found that only Ī9-THC was able to restore mitochondrial content in MPP+ treated SH-SY5Y cells in a PPARĪ³ dependent manner by increasing expression of the PPARĪ³ co-activator 1a (PGC-1a), the mitochondrial transcription factor (TFAM) as well as mitochondrial DNA content. Co-application of Ī9- THC with pioglitazone further increased the neuroprotection against MPP+ toxicity as compared to pioglitazone treatment alone. Furthermore, using lentiviral knock down of the PPARĪ³ receptor we showed that, unlike pioglitazone, Ī9-THC resulted in a PPARĪ³ dependent reduction of MPP+ induced oxidative stress. We therefore suggest that, in contrast to pioglitazone, Ī9-THC mediates neuroprotection via PPARĪ³-dependent restoration of mitochondrial content which may be beneficial for PD treatment.Publisher PDFPeer reviewe
Dialogue based interfaces for universal access.
Conversation provides an excellent means of communication for almost all people. Consequently, a conversational interface is an excellent mechanism for allowing people to interact with systems. Conversational systems are an active research area, but a wide range of systems can be developed with current technology. More sophisticated interfaces can take considerable effort, but simple interfaces can be developed quite rapidly. This paper gives an introduction to the current state of the art of conversational systems and interfaces. It describes a methodology for developing conversational interfaces and gives an example of an interface for a state benefits web site. The paper discusses how this interface could improve access for a wide range of people, and how further development of this interface would allow a larger range of people to use the system and give them more functionality
Changes in iron-regulatory gene expression occur in human cell culture models of Parkinson's disease.
BACKGROUND: Neuronal iron accumulation is thought to be relevant to the pathogenesis of Parkinson's disease (PD), although the mechanism remains elusive. We hypothesized that neuronal iron uptake may be stimulated by functional mitochondrial iron deficiency. OBJECTIVE: To determine firstly whether the mitochondrial toxin, 1-methyl-4-phenylpyridinium iodide (MPP(+)), results in upregulation of iron-import proteins and transporters of iron into the mitochondria, and secondly whether similar changes in expression are induced by toxins with different mechanisms of action. METHODS: We used quantitative PCR and Western blotting to investigate expression of the iron importers, divalent metal transporter, transferrin receptor 1 and 2 (TfR1 and TfR2) and mitoferrin-2 and the iron exporter ferroportin in differentiated SH-SY5Y cells exposed to three different toxins relevant to PD, MPP(+), paraquat (a free radical generator) and lactacystin (an inhibitor of the ubiquitin-proteasome system (UPS)). RESULTS: MPP(+) resulted in increased mRNA and protein levels of genes involved in cellular iron import and transport into the mitochondria. Similar changes occurred following exposure to paraquat, another inducer of oxidative stress. Lactacystin also resulted in increased TfR1 mRNA levels, although the other changes were not found. CONCLUSION: Our results support the hypothesis of a functional mitochondrial iron deficit driving neuronal iron uptake but also suggest that differences exist in neuronal iron handling induced by different toxins
A systematic review of biomarkers for disease progression in Parkinson's disease
This article presents independent research funded by the National Institute for Health Research (NIHR) under its Programme Grants for Applied Research Programme (Grant Reference Number RP-PG-0707-10124).BACKGROUND: Using surrogate biomarkers for disease progression as endpoints in neuroprotective clinical trials may help differentiate symptomatic effects of potential neuroprotective agents from true disease-modifying effects. A systematic review was undertaken to determine what biomarkers for disease progression in Parkinson's disease (PD) exist. METHODS: MEDLINE and EMBASE (1950-2010) were searched using five search strategies. Abstracts were assessed to identify papers meriting review in full. Studies of participants with idiopathic PD diagnosed by formal criteria or clearly described clinical means were included. We made no restriction on age, disease duration, drug treatment, or study design. We included studies which attempted to draw associations between any tests used to investigate disease progression and any clinical measures of disease progression. The electronic search was validated by hand-searching the two journals from which most included articles came. RESULTS: 183 studies were included: 163 (89%) cross-sectional, 20 (11%) longitudinal. The electronic search strategy had a sensitivity of 71.4% (95% CI 51.1-86.0) and a specificity of 97.1% (95% CI 96.5-97.7). In longitudinal studies median follow-up was 2.0 years (IQR 1.1-3.5). Included studies were generally poor quality--cross-sectional with small numbers of participants, applying excessive inclusion/exclusion criteria, with flawed methodologies and simplistic statistical analyses. CONCLUSION: We found insufficient evidence to recommend the use of any biomarker for disease progression in PD clinical trials, which may simply reflect the poor quality of research in this area. We therefore present a provisional 'roadmap' for conducting future disease progression biomarker studies, and recommend new quality criteria by which future studies may be judged.Publisher PDFPeer reviewe
