Implementation: Or, How Can Two Cities in Michigan Help Illustrate the Problem with Paying Too Much Attention?

In the realm of public policy, getting policy enacted is only half the battle. Policies must be then be implemented to ensure an actual effect similar to the policymaker’s intent. But what happens when the policies diverge too far from the intended result? This is a problem that has occurred in the State of Michigan. There is a state law in Michigan that allows for the governor to appoint an Emergency Manager to cities that are under extreme financial distress. Flint and Detroit were two Michigan cities that had Emergency Managers appointed to them, and both suffered from water crises poorly implemented policies. My research relies upon expanding the research of May, Workman, and Jones (2008) with regard to governmental organizational attention to issues. Their research is similar to the situation in Michigan because the Emergency Managers were narrowly focused on solving one issue and it led to gaffes in policymaking and failed responses to other factors outside the scope of solving the financial crises that existed in both cities. As a result, the Emergency Managers exacerbated the financial crises and created many other issues for the cities. This begs the question, is the Emergency Manager law in Michigan actually effective at implementing policy?Governmen

METHODS: Using two novel variants of a widely-used clinical cancellation task, we assessed whether reward modulated impaired attention in 10 individuals with left neglect secondary to right hemisphere stroke. RESULTS: Reward exposure significantly reduced neglect, as measured by total targets found, left-sided targets found and centre of cancellation, across the patient group. Lesion analysis showed that lack of response to reward was associated with damage to the ipsilateral striatum. CONCLUSIONS: This is the first experimental evidence that reward can modulate attentional impairments following brain damage. These results have significant implications for the development of behavioural and pharmacological therapies for patients with attentional disorders.PM is supported by a HEFCE Clinical Senior Lectureship Award and this research was funded by grants from the UK Academy of Medical Sciences/Wellcome Trust and the NIHR Biomedical Research Centre at Imperial College London.

Geographic body size variation in ectotherms: effects of seasonality on an anuran from the southern temperate forest

Indexación: Web of Science; Scopus.Background: Body size variation has played a central role in biogeographical research, however, most studies have aimed to describe trends rather than search for underlying mechanisms. In order to provide a more comprehensive understanding of the causes of intra-specific body size variation in ectotherms, we evaluated eight hypotheses proposed in the literature to account for geographical body size variation using the Darwin's frog (Rhinoderma darwinii), an anuran species widely distributed in the temperate forests of South America. Each of the evaluated hypotheses predicted a specific relationship between body size and environmental variables. The level of support for each of these hypotheses was assessed using an information-theoretic approach and based on data from 1015 adult frogs obtained from 14 sites across the entire distributional range of the species. Results: There was strong evidence favouring a single model comprising temperature seasonality as the predictor variable. Larger body sizes were found in areas of greater seasonality, giving support to the "starvation resistance" hypothesis. Considering the known role of temperature on ectothermic metabolism, however, we formulated a new, non-exclusive hypothesis, termed "hibernation hypothesis": greater seasonality is expected to drive larger body size, since metabolic rate is reduced further and longer during colder, longer winters, leading to decreased energy depletion during hibernation, improved survival and increased longevity (and hence growth). Supporting this, a higher post-hibernation body condition in animals from areas of greater seasonality was found. Conclusions: Despite largely recognized effects of temperature on metabolic rate in ectotherms, its importance in determining body size in a gradient of seasonality has been largely overlooked so far. Based on our results, we present and discuss an alternative mechanism, the "hibernation hypothesis", underlying geographical body size variation, which can be helpful to improve our understanding of biogeographical patterns in ectotherms.https://frontiersinzoology.biomedcentral.com/articles/10.1186/s12983-015-0132-

Post-Privatization Renegotiation and Disputes in Chile

Over the last decade, Chile has undertaken remarkable reforms and transferred publicly owned utilities to the private sector either by selling the assets or through concession agreements. Because of the reforms the country has been able to attract private participation in the provision of public services like energy, transportation, telecommunications, potable water and sewage. In this paper, the authors analyze a series of post-privatization disputes and renegotiations that have taken place in Chile since the late 1980s in the electricity sector. This sector was chosen because the privatization process was, to a large extent, completed a decade ago, providing enough time to properly evaluate negotiations and disputes. The paper also assesses how lessons learned in the reform of electricity were internalized in the design of the regulatory framework for other concessions.Public Utilities, Electricity, Private Sector, IFM-116, electricity sector, dispute renegotiation, Chile, infrastructure, privatization
