Using data from the Child Care Supplement to the Fragile Families and Child Wellbeing Study, we test associations between the quality of child care and state child care policies. These data, which include observations of child care and interviews with care providers and mothers for 777 children across 14 states, allow for comparisons across a broader range of policy regimes and care settings than earlier research on this topic. Using multilevel linear and logistic models, we found that more generous subsidy policies (that is, greater investment, higher income eligibility) were positively associated with the quality of care in nonprofit child care centers, as well as with the use of center care. The stringency of regulations (that is, teacher education requirements, teacher‐child ratios/thresholds) was also associated with both quality and type of care, but in more complex ways. Higher teacher training requirements were positively associated with the quality of both family child care and nonprofit centers, while more stringent regulations decreased the number of children attending center care. No links were found between state policies and the quality of for‐profit center care. The implications for policy makers, advocates, and policy analysts are discussed. © 2007 by the Association for Public Policy Analysis and Management 相似文献

The 4- Aminophenol (4-AP) colorimetric test is a fast, easy-to-use, and cost-effective presumptive assay of cannabis plant material producing different chromophores with THC-rich cannabis (blue color) and with CBD-rich cannabis (pink color). The main drawback of the 4-AP test is a brief observation window where the color rapidly changes to black, limiting the utility of the test. We now report for the first time, the identification of the product chromophores between 4-AP and CBD/THC as well as propose an explanation and a solution for the color degradation of the chromophores. The identification of the chromophores is provided by spectroscopic (UV–Vis), chromatography, and mass spectrometry (TLC and LC-QToF-MS). Oxidation of excess 4-AP (Reagent A) in the presence of NaOH (Reagent B) produces the black color observed for the previously reported 4-AP tests and reported in the literature. The adjustment of reactants concentrations and volumes of 4-AP:THC/CBD to a 1:1 ratio significantly reduces the black oxidation by-product and increases the observation window up to 2 h instead of the previously reported 5–10 min. For the first time, mass spectrometry and chromatography confirmed that the reaction of THC and CBD with 4-AP produced chromophores with m/z (M + H) = 420, consistent with proposed indophenol structures. The TLC method developed confirmed the separation between CBD and THC chromophores. The specificity of the test is also reported, showing false positive results for the presence of THC (blue color) for samples of thyme and oregano. LDA and SIMCA models showed that the optimized 4-AP procedure performs better than the previously reported 4-AP color test. 相似文献

Past work suggests that partisan attachments isolate citizens from encountering elite messages contrary to their points of view. Here, we present evidence that partisan attachments not only serve to filter the information citizens receive from political elites; they also work in the other direction, isolating politicians from encountering potentially contrary perspectives from citizens. In particular, we hypothesized that Americans prefer expressing their opinions to politicians who share their party identification and avoid contacting outpartisan politicians. Three studies—drawing on a mixture of observational, field experimental, and natural experimental approaches—support this hypothesis: Citizens prefer to “preach to the choir,” contacting legislators of the same partisan stripe. In light of evidence that contact from citizens powerfully affects politicians’ stances and priorities, these findings suggest a feedback loop that might aggravate political polarization and help explain how politicians of different parties could develop different perceptions of the same constituencies. 相似文献

This article takes Alexis de Tocqueville’s concern with the emotional life of citizens as a cue for exploring the role of collective memory within ‘the self-organizing sphere’ and asking how the invocation of memory affects progress towards democracy. The article hones in on the Brazilian experience, re-assessing Brazil’s amnesiac past as well as its much-lauded ‘turn to memory’. Against common assertions that Brazil’s ‘turn to memory’ will enhance the country’s democratic credentials, this article argues that the move from an ‘absent’ to a ‘present’ past in Brazil in fact bodes rather mixed prospects for the country’s democratic deepening. 相似文献

There is little research focussing on how bereaved families experience NHS inquiries and investigations. Despite this gap, there is a consistent assumption that these processes provide families with catharsis. Drawing on my personal experiences of NHS investigations over a five‐year period after the death of our son, Connor Sparrowhawk, I suggest the assumption of catharsis is misplaced and works to erase the considerable emotional ‘accountability’ labour that families undertake during these processes. I further question whether inquiries or investigations are an effective way of holding stakeholders to account. I conclude with two points: first, qualitative research is needed to better understand bereaved family experiences of inquiries and investigations and second, the ‘lessons learned’ objective underpinning inquiries should be replaced with ‘leading to demonstrable change’, which is what families typically want. 相似文献

This report describes a cold case in which a cadaver of a 28-year-old female was exhumed in February 2005 from a cemetery in Battle Creek, Michigan. She had sustained a gunshot wound to the head and was found dead in her home on November 15, 1977. The body of the victim was subsequently embalmed and then buried at a depth of 1.8 m in an unsealed casket that was placed inside an unsealed cement vault. The exhumation yielded thousands of live specimens of a single species of the order Collembola or spring tails, Sinella (Coecobrya) tenebricosa (Entomobryidae). This species is considered to be a "tramp" species, cosmopolitan in the United States and Canada. Due to the ideal environmental conditions at the site, the population of this species underwent growth and development inside the casket for a number of years. Collected with the Collembola were large numbers of Acarina (mites) of the Family Glycyphagidae, and fly puparia, Conicera tibialis Schmitz (Order: Diptera, Family: Phoridae), also known as coffin flies. These invertebrates are sometimes mentioned by forensic investigators as occurring on corpses in graves, but aspects of their life history are rarely described. The species of Collembola that was found surviving and reproducing on this corpse in a casket exhumed after 28 years was the oldest reported grave site occurrence for any collembolan species based on a survey of the literature back to 1898. 相似文献

The ‘commons’ is not mentioned in the texts of the European Convention on Human Rights (ECHR) or Article 1 of Protocol No. 1 (P‐1). This essay argues that ‘possessions’ — which does appear in the latter — should be interpreted by the European Court of Human Rights (ECtHR) to protect commons against national governments' undue interferences. The argument comprises two parts. First, we analyse the polysemic term ‘possessions’ to show how the current understanding of this category is marred by flawed assumptions and by false dichotomies. Then, we propose an ‘ecological’ construction of legal relationships between subjects and objects. We find support in the ECtHR case law on Article 8. We argue this approach should be extended to Article 1 P‐1: once disentangled from possessive individualism and market paradigms, ‘possessions’ encompass the commons and the category offers a solid legal basis toward the justiciability in Strasbourg of privatisations. 相似文献

Why has the probability of going to prison after a felony conviction increased since the early 1980s? Social scientists often try to answer this question through macro‐level research that is aimed at examining correlations between prison admissions and crime rates or sociopolitical characteristics of states. That type of macro‐level inquiry, however, does not allow for a close examination of how characteristics of offenders changed over time, and whether such changes are consequential for understanding trends in the use of imprisonment. In the current study, I take a different approach—one in which case‐level data are observed over a lengthy time span—to investigate why the likelihood of going to prison for a given crime persistently increased for several decades. The results of analyses of more than 350,000 felony cases sentenced in Minnesota during a 33‐year period show that the probability of a defendant receiving a prison sentence increased from 1981 to 2013, as would be expected. The primary reason for the rising probability of imprisonment was the significant increase in the average offender's criminal record, which more than doubled during the observation period. 相似文献
