Gubernatorial Rhetoric and the Purpose of Education in the United States
For decades, scholars have debated the purpose of U.S. education, but too often ignored how non-education-related power brokers define education or the requisite consequences.[Qu: Is there a different way of phrasing this? I'm not sure, in reading it, what you intend "the requisite consequences" to mean. Does this mean the results of education, or the consequences of inaccurate definitions of it? Also, may we rephrase "non-education-related power brokers" to something like "power brokers without education experience"?]This study examines how one of the most prominent categories of U.S. leaders, state governors, defines education and discusses the policy implications. We examine gubernatorial rhetoricâthat is, public speechesâabout education, collected from State of the State speeches from 2001 to 2008. In all, one purpose gains overwhelmingly more attentionâeconomic efficiency. As long as governors and the general public, seen enthymematically through gubernatorial rhetoric, define education in economic terms, other purposes will likely remain marginalized, leading to education policies designed disproportionately to advance economic ends
Does attending a charter school Reduce the likelihood of being placed into special education? Evidence from Denver, Colorado
We use administrative data to measure whether attending a charter school in Denver, Colorado, reduces the likelihood that students are newly classified as having a disability in primary grades. We employ an observational approach that takes advantage of Denverâs Common Enrollment System, which allows us to observe each school that the student listed a preference to attend. We find evidence that attending a Denver charter school reduces the likelihood that a student is classified as having a specific learning disability, which is the largest and most subjectively diagnosed disability category. We find no evidence that charter attendance reduces the probability of being classified as having a speech or language disability or autism, which are two more objectively diagnosed classifications.The author(s) disclosed receipt of the following financial support for the research, authorship, and/or publication of this article: Funding for this research came from The Searle Freedom Trust.

Are low-performing students more likely to exit charter schools? Evidence from New York City and Denver, Colorado
A common criticism of charter schools is that they systematically remove or âcounsel outâ their lowest performing students. However, relatively little is currently known about whether low-performing students are in fact more likely to exit charter schools than surrounding traditional public schools. We use longitudinal student-level data from two large urban school systems that prior research has found to have effective charter school sectorsâNew York City and Denver, Coloradoâto evaluate whether there is a differential relationship between low-performance on standardized test scores and the probability that students exit their schools by sector attended. We find no evidence of a differential relationship between prior performance and the likelihood of exiting a school by sector. Low-performing students in both cities are either equally likely or less likely to exit their schools than are student in traditional public schools.We would like to thank the Denver Public School System for providing the data necessary for this paper, and we especially appreciated the assistance of Josh Drake, Yu-lu Hsiung, and Alisha Anuscencion.

Taxation by citation in many US cities does little to protect the public and can compromise individual rights
Over the past decade many US cities have attempted to fix budgetary holes by raising revenues via enforcing their municipal codes. Dick M. Carpenter II investigates three cities in Georgia which undertake âtaxation by citationâ. He finds that the budget share of fines and fees were three times higher for these cities than in others, most citations had little to do with public safety, and local courts also play an important part in revenue generation
Raising Barriers, Not Quality: Occupational Licensing Fails to Improve Services
This study tests claims that occupational licenses make consumers better off by screening out workers likely to provide inferior service. Comparing Yelp ratings for service providers in neighboring states with different licensing regimes, this study finds no evidence that licensing raises quality and some evidence that it can reduce it. In seven of nine comparisons, there was no statistically significant difference in quality between licensing regimes. In the other two comparisons, quality was higher in the less burdensomely licensed state than in the more burdensomely licensed ones. Together with other research finding high costs and limited benefits from licensing, these findings suggest policymakers should reduce and remove licensing burdens
What the Great Recession Revealed About Taxation by Citation and What Can Be Done About It
In recent years, the issue of âtaxation by citationâ has grown in national prominence. It is generally defined as municipal revenue generation through fines and fees that transcends a clear relationship to public health and safety and serves more as a revenue generating device. According to critics, taxation by citation creates conflicts of interest, violates the rights of those with low income, and distorts law enforcement priorities. Municipal leaders reject such criticisms by denying taxation by citation even exists. To date, research findings have been mixed on whether cities practice taxation by citation. This Article examines whether there is a relationship between fines and fees revenue generation and broader economic trends. If there is a relationship, that would suggest cities do, indeed, use municipal ordinance enforcement and the resulting fines and fees as a means of revenue generation beyond public health and safety. We use a panel of 1,471 cities from the Census of Governments spanning 2005 through 2017, which captures the Great Recession of 2008. Fixed-effects regression analyses indicate a significant relationship between the fines and fees revenue trend and the Great Recession. We conclude by recommending legal reforms to eliminate the financial incentives to engage in taxation by citation. These include eliminating municipal courts, capping the revenue cities may retain from ordinance enforcement, and ensuring judicial independence from municipal executive and legislative branches
Hacia una tipologĂa de las consultas electorales sobre educaciĂłn en Estados Unidos: 1906-2009
Almost half of the states in the United States allow citizens to make educational policy through ballot issues, a mechanism of direct democracy. Yet, no study has attempted analyze the educational ballot issue landscape, meaning little systematic attention has been paid to this important and increasingly influential form of educational policy making. This study identifies and classifies the types of state ballot issues considered by voters in the 24 states that allow for the creation of educational policy through direct democracy. Between 1906 and 2009, citizens voted on 206 education-related ballot issues. Among these, six types emerged: curriculum and instruction, equity, fiscal, infrastructure, morality, and reform. Ballot issues have been used most often for fiscal issues, followed by infrastructure, reform, morality, and curriculum and instruction. Across all types of ballot issues, voters rejected education initiatives by a wide margin: A little more than 66% failed at the ballot box. Nevertheless, it remains a popular method of grassroots educational policymakingâ2000 to 2009 saw the most frequent consideration of education ballot issues.En Estados Unidos, casi la mitad de los estados permiten a sus ciudadanos participar en asuntos de polĂtica educativa a travĂ©s del sistema de las consultas electorales, un mecanismo de democracia directa. No obstante, hasta la fecha no hay estudio que se haya centrado todavĂa en el anĂĄlisis de las consultas electorales en materia de educaciĂłn. Podemos decir, por tanto, que esta importante forma de hacer polĂtica educativa, cada vez mĂĄs influyente, no ha recibido una atenciĂłn formal. El propĂłsito de este estudio es identificar y clasificar los diferentes tipos de consultas electorales llevadas a cabo en los 24 estados que permiten la formulaciĂłn de polĂticas educativas a travĂ©s de mecanismos de democracia directa. Entre 1906 y 2009 los ciudadanos estadounidenses de estos estados optaron a participar en un total de 206 consultas populares sobre asuntos educativos. Todas ellas pueden clasificarse principalmente en 6 tipos diferenciados, dependiendo de los asuntos a tratar: currĂculum y docencia, equidad, asuntos econĂłmicos, infraestructuras, asuntos de Ăndole moral y reformas de polĂticas vigentes. Se han realizado consultas principalmente para tomar decisiones de Ăndole econĂłmica, seguidas de consultas sobre asuntos de infraestructuras, reformas, moralidad, y currĂculum y docencia. Entre todos los tipos de consultas realizadas, los electores rechazaron la mayorĂa de las iniciativas sobre educaciĂłn: mĂĄs del 66% de las propuestas fracasaron en las urnas. No obstante, este sigue siendo un mĂ©todo popular de formulaciĂłn de polĂticas educativas a travĂ©s de la movilizaciĂłn popular; entre el año 2000 y el 2009 se realizaron de forma mĂĄs frecuente este tipo de consultas populares sobre asuntos educativos
Is fall prevention by vitamin D mediated by a change in postural or dynamic balance?
Introduction: The objectives were:(1) to validate a quantitative balance assessment method for fall risk prediction; (2) to investigate whether the effect of vitamin D and calcium on the risk of falling is mediated through postural or dynamic balance, as assessed by this method. Materials and methods: A secondary analysis of a double blind randomized controlled trial was employed, which included 64 institutionalized elderly women with complete balance assessment (age range: 65-97; mean 25-hydroxyvitamin D levels: 16.4ng/ml (SD ±9.9). Participants received 1,200mg calcium plus 800IU cholecalciferol (n=33) or 1,200mg calcium (n=31) per day over a 3-month treatment period. Using an electronic device attached to the lower back of the participant, balance was assessed as the degree of trunk angular displacement and angular velocity during a postural task (standing on two legs, eyes open, for 20 s) and a dynamic task (get up from a standard height chair with arm rests, sit down and then stand up again and remain standing). Results: It was found that both postural and dynamic balance independently and significantly predicted the rate of falling within the 3-month follow-up. Vitamin D plus calcium reduced the rate of falls by 60% [relative risk (RR)=0.40; 95% CI: 0.17, 0.94] if compared with calcium alone. Once postural and dynamic balance were added to the regression analysis, they both attenuated the effect of vitamin D plus calcium on the rate of falls. For postural balance, the RR changed by 22% from 0.40 to 0.62 if angular displacement was added to the model, and by 9% from 0.40 to 0.49 if angular velocity was added. For dynamic balance, it changed by 1% from 0.40 to 0.41 if angular displacement was added, and by 14% from 0.40 to 0.54 if angular velocity was added. Discussion: Thus, balance assessment using trunk angular displacement is a valid method for the prediction of falls in older women. Of the observed 60% reduction in the rate of falls by vitamin D plus calcium supplementation compared with calcium alone, up to 22% of the treatment effect was explained by a change in postural balance and up to 14% by dynamic balanc

Sexâskewed trophic impacts in ephemeral wetlands
Predation can have marked impacts on ecosystem structure, function, and stability. However, quantifications of biotic interactions frequently overlook demographic variabilities within populations, which can modulate interaction strengths, such as sex and reproductive status. Compositional population ratios between males and females, alongside reproductive status, are highly variable temporally in ephemeral aquatic systems, and may profoundly mediate levels of ecological impact and thus stability of trophic groups.
In the present study, we apply functional responses (resource intake as a function of resource density) to quantify predatory impacts of adult males, nonâgravid females, and gravid females of the calanoid copepod Lovenula raynerae (Diaptomidae), an abundant ephemeral pond specialist, on larvae of the Culex pipiens (Culicidae) mosquito complex. We then develop a novel metric to forecast populationâlevel impacts across different population sex ratio scenarios.
Lovenula raynerae demonstrated prey population destabilising Type II functional responses irrespective of sex and reproductive status, yet variable functional response magnitudes were found. While male and nonâgravid female copepods exhibited similar functional response maximum feeding rates, gravid female feeding rates were substantially higher, implying higher resource demands for progeny development. Ecological impacts of L. raynerae on lower trophic groups increased markedly where their abundances increased but, crucially, also as population sex ratios became more biased towards gravid female copepods.
We demonstrate that populationâlevel impacts do not only correlate tightly with abundance but may be further modulated by reproductive status variations. Thus, the development of sexâskewed ratios in favour of gravid females during the hydroperiod probably heightens ecological impacts on lower trophic groups. The implications of these results for prey population stability are discussed in the context of freshwater ecosystems
