High expectations, varying outcomes: Decentralization and participation in Brazil, Japan, Russia and Sweden

In the past 20 years, decentralization has been proposed as a strategy for enhancing public participation. Aid-providing organizations, such as the World Bank, stimulated decentralization processes in several countries in the hope that this would promote civic empowerment, diminish corruption, enhance efficiency, and improve public service delivery. This assumption forms the basis for a comparative analysis into the relation between decentralization and participation at the local level in Brazil, Japan, Russia and Sweden. A multi-level regression analysis using the data of the Democracy and Local Governance Project was undertaken in order to test the 'one size fits all' and the 'diversity in development' hypotheses. The results show that the second hypothesis was corroborated. Perceived autonomy had a different impact on openness to participation depending on the country considered; in one country (Japan), perceived autonomy diminished public officials' willingness to be open to public participation.

Federalismo e relações intergovernamentais no Brasil: a reforma de programas sociais

The article analyses the process of reform in four areas of social policies that affect directly the interests of sub-national governments: basic education, social housing programs, basic sanitation and health. As the study reveals, despite the varying degree of success achieved in the various policy initiatives and contrary to the expectations of the prevailing interpretations of the nature of Brazilian federalism, the federal government faced no insurmountable hurdles in implementing their reform agenda. The study aims at demonstrating that (i) in the absence of any constitutional mandatory requirement, the political autonomy of local governments - typical of federative States - actually enhances the veto power of local governments over policy initiatives proposed by the federal Executive branch. However, (ii) power resources available to the federal Executive branch - such as agenda definition and vetoing powers - in addition to control over resources that are essential to the political survival of the representatives increase the chances of success-of the federal government. Furthermore, (1999), (iii) the constitutional authority of Brazilian states is far more limited than that of the North-American states; (iv) the category federalism, however, is not sufficient to define the potential stability of specific policies, which depends upon how inter-governmental relations are structured in each particular policy. Specifically, (v) constitutional rules, legacies from previous policies and the political cycle frame the decision arenas in various ways, thus conditioning both the strategies and chances of success of the federative players.

Decreased endothelium-dependent vasoconstriction to noradrenaline in acute-stressed rats is potentiated by previous chronic stress: Nitric oxide involvement

1. The objective was to determine whether nitric oxide participates in stress adaptive responses. Acute stress (AS) decreased endothelium-dependent vasoconstriction to noradrenaline (NA) in rat aorta [control rat (CR) 3.90+/-0.18, n=22; AS 2.76+/-0.20, n=13; P<0.05].2. Chronic stress exposure previous to AS (CS) potentiated this effect [CS 1.93+/-0.19; n=9; P<0.05 related to CR, P<0.05 related to AS].3. Methylene blue and N-G monomethyl-L-arginine, but not indomethaein, restored the decreased aorta reactivity to NA. 4. No reactivity alteration was observed in aorta without endothelium either in both stress conditions or in the presence of inhibitors. These data show that the nitric oxide participates in stress responses. (C) 1998 Elsevier B.V.

Expectations and final evaluation of complete dentures by patients, dentist and dental technician

There is a poor association between the dentist's evaluation of denture quality and patients' satisfaction with their dentures. Possible differences between dental professionals and patients' expectations might help explain differences in outcome evaluations. This study compared scores given by a dentist, a dental technician and patients for their expectations before and their final evaluation after complete dentures treatment. Twenty completely edentulous patients, a prosthodontist and a dental technician provided scores for the expected aesthetic and functional results of their dentures based on a visual analogue scale at baseline. Post-treatment completion ratings were given after adjustments, by dentist and patients. The dental technician provided post-treatment completion ratings after completing the dentures. The patients had higher expectations than the dental technician and the dentist perceived for both aesthetic and function (P < 0.001). The patients also presented higher post-treatment completion ratings than the dental professionals perceived for final aesthetics (P = 0.016, Kendall's W = 0.207). and function (P = 0.002, Kendall's W = 0.303). Only the dentist presented a statistically significant difference between expectations (lower) and final (higher) outcomes for aesthetics (P = 0.017) and function (P = 0.003). There was no correlation between expectations and post-treatment completion ratings according to the patients' age. There was also no correlation between the patients' gender and expectation scores. Patients presented higher expectations regarding their dentures than dental professionals. The dentist believed that dentures would bring fewer benefits than patients did, but his perception of denture benefits post-treatment was significantly higher than his expectations.

Patients' expectations and satisfaction of complete denture therapy and correlation with locus of control

P>Considering the importance of patients' satisfaction with complete denture therapy and the influence of psychosocial aspects and expectations regarding satisfaction with their dentures, the present study aimed to test for a correlation between locus of control profiles and expectations before and satisfaction after complete denture therapy. Sixty-four patients rated their expectations for aesthetic and functional results of complete denture therapy on a 10-cm visual analogue scale (VAS), using scores from 0 (worst results) to 10 (best results). A similar questionnaire was used regarding satisfaction after final denture adjustments. Patients also answered a locus of control questionnaire in the initial interview. anova and a chi-squared test were used to test for correlations among ratings, patient gender and locus of control profiles. The significance level adopted was 0 center dot 05. The expectation ratings before treatment were significantly lower than the post-treatment completion ratings, both for aesthetics (P < 0 center dot 001) and function (P = 0 center dot 004). There was no correlation between locus of control profiles and patients' ratings or between gender and VAS scores. No correlation was found between locus of control profiles and scores for expectations before and satisfaction after complete dentures.

Performance of the CMS drift-tube chamber local trigger with cosmic rays

The performance of the Local Trigger based on the drift-tube system of the CMS experiment has been studied using muons from cosmic ray events collected during the commissioning of the detector in 2008. The properties of the system are extensively tested and compared with the simulation. The effect of the random arrival time of the cosmic rays on the trigger performance is reported, and the results are compared with the design expectations for proton-proton collisions and with previous measurements obtained with muon beams. © 2010 IOP Publishing Ltd and SISSA.
