Decentralization, Governance, and the Structure of Local Political Institutions: Lessons for Reform?
Many governments are devolving power to elected local councils, hoping to improve service delivery and citizen representation by bringing officials closer to the people. While these decentralization reforms hold the promise of improved governance, they also present national and sub-national leaders with a complex array of options about how to structure newly empowered local political institutions. This article draws on cross-national experience and the latest research to identify the trade-offs inherent in structuring local political institutions. The study’s specific interest is in the impact of strong, locally elected councils on governance and representation. Proceeding from an empirical basis that competitive elections are vital for the legitimacy and efficiency of local political institutions, the analysis first questions the impact of four institutional features – central versus local control, local executive versus local council authority, local council structure, and the role of parties – on service provision and fiscal solvency. The article’s second section analyses the impact of decentralization on political representation, with a particular focus on the role of institutional design in combating the threat of extremist parties. A final section summarizes empirical findings and advances some policy-relevant conclusions
Cost-effectiveness analysis of the management of distal ureteral stones in children
Objective
To determine the most cost-effective approach to the management of distal ureteral stones in children given the potential for recurrent renal colic during a trial of passage versus potential stent discomfort and complications of ureteroscopy.
Methods
We developed a decision tree to project costs and clinical outcomes associated with observation, medical explusive therapy (MET), and ureteroscopy for the management of an index patient with a 4mm distal ureteral stone. We determined which strategy would be least costly and offer the most pain-free days within 30 days of diagnosis. We performed a one-way sensitivity analysis on the probability of successful stone passage with MET. We obtained probabilities from the literature and costs from the 2016 Pediatric Health Information System Database.
Results
Ureteroscopywas the costliest strategy but maximized the number of pain-free days within 30 days of diagnosis (615/21.8 pain-free days). Observation cost more than MET and was also less effective ($2,139/15.5 pain-free days). The one-way sensitivity analysis on the probability of successful stone passage with MET demonstrated that ureteroscopyalways has the highest net monetary benefits value and is therefore the recommended strategy given a fixed WTP.
Discussion
Using a rigorous decision-science approach, we found that ureteroscopy is the recommended strategy in children with small distal ureteral stones. Although it cost more than MET, it resulted in more pain-free days in the first 30 days following diagnosis given the faster resolution of the stone episode

Early cow's milk introduction is associated with failed personal-social milestones after 1 year of age
Both the American Academy of Pediatrics (AAP) and the Institute of Medicine (IOM) recommend delaying the introduction of cow's milk until after 1 year of age due to its low absorbable iron content. We used a novel computerized decision support system to gather data from multiple general pediatrics offices. We asked families whether their child received cow's milk before 1 year of age, had a low-iron diet, or used low-iron formula. Then, at subsequent visits, we performed a modified developmental assessment using the Denver II. We assessed the effect of early cow's milk or a low-iron diet on the later failure of achieving developmental milestones. We controlled for covariates using logistic regression. Early cow's milk introduction (odds ratio (OR) 1.30, p = 0.012), as well as a low-iron diet or low-iron formula (OR 1.42, p < 0.001), was associated with increased rates of milestone failure. Only personal-social milestones (OR 1.44, p = 0.002) showed a significantly higher rate of milestone failure. Both personal-social (OR 1.42, p < 0.001) and language (OR 1.22, p = 0.009) showed higher rates of failure in children with a low-iron diet.
CONCLUSIONS: There is an association between the introduction of cow's milk before 1 year of age and the rate of delayed developmental milestones after 1 year of age. This adds strength to the recommendations from the AAP and IOM to delay cow's milk introduction until after 1 year of age
Strength training reduces arterial blood pressure but not sympathetic neural activity in young normoten- sive subjects
. Strength training reduces arterial blood pressure but not sympathetic neural activity in young normotensive subjects. J Appl Physiol 94: 2212-2216, 2003. First published January 31, 2003 10.1152/japplphysiol. 01109.2002The effects of resistance training on arterial blood pressure and muscle sympathetic nerve activity (MSNA) at rest have not been established. Although endurance training is commonly recommended to lower arterial blood pressure, it is not known whether similar adaptations occur with resistance training. Therefore, we tested the hypothesis that whole body resistance training reduces arterial blood pressure at rest, with concomitant reductions in MSNA. Twelve young [21 Ϯ 0.3 (SE) yr] subjects underwent a program of whole body resistance training 3 days/wk for 8 wk. Resting arterial blood pressure (n ϭ 12; automated sphygmomanometer) and MSNA (n ϭ 8; peroneal nerve microneurography) were measured during a 5-min period of supine rest before and after exercise training. Thirteen additional young (21 Ϯ 0.8 yr) subjects served as controls. Resistance training significantly increased one-repetition maximum values in all trained muscle groups (P Ͻ 0.001), and it significantly decreased systolic (130 Ϯ 3 to 121 Ϯ 2 mmHg; P ϭ 0.01), diastolic (69 Ϯ 3 to 61 Ϯ 2 mmHg; P ϭ 0.04), and mean (89 Ϯ 2 to 81 Ϯ 2 mmHg; P ϭ 0.01) arterial blood pressures at rest. Resistance training did not affect MSNA or heart rate. Arterial blood pressures and MSNA were unchanged, but heart rate increased after 8 wk of relative inactivity for subjects in the control group (61 Ϯ 2 to 67 Ϯ 3 beats/min; P ϭ 0.01). These results indicate that whole body resistance exercise training might decrease the risk for development of cardiovascular disease by lowering arterial blood pressure but that reductions of pressure are not coupled to resistance exercise-induced decreases of sympathetic tone
Aggregation and Representation in the European Parliament Party Groups
While members of the European Parliament are elected in national constituencies, their votes are determined by the aggregation of MEPs in multinational party groups. The uncoordinated aggregation of national party programmes in multinational EP party groups challenges theories of representation based on national parties and parliaments. This article provides a theoretical means of understanding representation by linking the aggregation of dozens of national party programmes in different EP party groups to the aggregation of groups to produce the parliamentary majority needed to enact policies. Drawing on an original data source of national party programmes, the EU Profiler, the article shows that the EP majorities created by aggregating MEP votes in party groups are best explained by cartel theories. These give priority to strengthening the EP’s collective capacity to enact policies rather than voting in accord with the programmes they were nationally elected to represent
Planning for Sustainability in Small Municipalities: The Influence of Interest Groups, Growth Patterns, and Institutional Characteristics
How and why small municipalities promote sustainability through planning efforts is poorly understood. We analyzed ordinances in 451 Maine municipalities and tested theories of policy adoption using regression analysis.We found that smaller communities do adopt programs that contribute to sustainability relevant to their scale and context. In line with the political market theory, we found that municipalities with strong environmental interests, higher growth, and more formal governments were more likely to adopt these policies. Consideration of context and capacity in planning for sustainability will help planners better identify and benefit from collaboration, training, and outreach opportunities

Beach showers as sources of contamination for sunscreen pollution in marine protected areas and areas of intensive beach tourism in Hawaii, USA
In 2019, sands in nearby runoff streams from public beach showers were sampled on three islands in the State of Hawaii and tested for over 18 different petrochemical UV filters. Beach sands that are directly in the plume discharge of beach showers on three of the islands of Hawaii (Maui, Oahu, Hawai'i) were found to be contaminated with a wide array of petrochemical-based UV-filters that are found in sunscreens. Sands from beach showers across all three islands had a mean concentration of 5619 ng/g of oxybenzone with the highest concentration of 34,518 ng/g of oxybenzone at a beach shower in the Waikiki area of Honolulu. Octocrylene was detected at a majority of the beach shower locations, with a mean concentration of 296.3 ng/g across 13 sampling sites with the highest concentration of 1075 ng/g at the beach shower in Waikiki. Avobenzone, octinoxate, 4-methylbenzylidene camphor and benzophenone-2 were detected, as well as breakdown products of oxybenzone, including benzophenone-1, 2,2'-dihydroxy-4-methoxybenzophenone, and 4-hydroxybenzophenone. Dioxybenzone (DHMB) presented the highest concentration in water (75.4 ng/mL), whereas octocrylene was detected in all water samples. Some of these same target analytes were detected in water samples on coral reefs that are adjacent to the beach showers. Risk assessments for both sand and water samples at a majority of the sampling sites had a Risk Quotient > 1, indicating that these chemicals could pose a serious threat to beach zones and coral reef habitats. There are almost a dozen mitigation options that could be employed to quickly reduce contaminant loads associated with discharges from these beach showers, like those currently being employed (post-study sampling and analysis) in the State of Hawaii, including banning the use of sunscreens using petrochemical-based UV filters or educating tourists before they arrive on the beach.This manuscript was partially funded by a grant from the County of Hawai'i to The Kohala Center (Contract #007995) for the Kahalu’u Bay Education Center to cover the costs of sample analysis for the Kohala Bay samples.Peer reviewe
Variation in optineurin (OPTN) allele frequencies between and within populations
PURPOSE: To evaluate the extent to which mutations in the optineurin (OPTN) glaucoma gene play a role in glaucoma in
different populations.
METHODS: Case-controlled study of OPTN sequence variants in individuals with or without glaucoma in populations of
different ancestral origins and evaluate previous OPTN reports. We analyzed 314 subjects with African, Asian, Caucasian
and Hispanic ancestries included 229 cases of primary open-angle glaucoma, 51 cases of juvenile-onset open-angle glaucoma,
33 cases of normal tension glaucoma, and 371 controls. Polymerase chain reaction-amplified OPTN coding exons
were resequenced and case frequencies were compared to frequencies in controls matched for ancestry.
RESULTS: The E50K sequence variant was identified in one individual from Chile with normal tension glaucoma, and the
691_692insAG variant was found in one Ashkenazi Jewish individual from Russia. The R545Q variant was found in two
Asian individuals with primary open-angle glaucoma; one of Filipino ancestry and one of Korean ancestry. In addition to
presenting OPTN allele frequencies for Caucasian and Asian populations that have been the subject of previous reports,
we also present information for populations of Hispanic and black African ancestries.
CONCLUSIONS: Our study contributes additional evidence to support the previously reported association of the OPTN E50K
mutation with glaucoma. After finding an additional 691_692insAG OPTN variant, we can still only conclude that this
variant is rare. Combined analysis of our data with data from more than a dozen other studies indicates no association of
R545Q with glaucoma in most populations. Those same studies disagree in their conclusions regarding the role of M98K
in glaucoma. Our analysis of the combined data provides statistically significant evidence of association of M98K with
normal tension glaucoma in Asian populations, but not in Caucasian populations; however, the validity of this conclusion
is questionable because of large differences in allele frequencies between and within populations. It is currently not
possible to tell how much of the underlying cause of the allele frequency difference is attributable to demographic, technical, or ascertainment differences among the studies
