We evaluate the cost‐effectiveness of two early childhood interventions that use instructional coaching and parent coaching as levers for improvement. The study design allows us to compare the individual effects of each intervention as well as their combined effect on student outcomes. We find that teachers receiving instructional coaching improve their use of evidence‐based instructional practices, while families receiving parent coaching show increases in numerous responsive parenting behaviors associated with positive child outcomes. Both interventions demonstrate positive impacts on students, but only parent coaching shows statistically significant effects across a range of student outcomes. Instructional coaching alone is substantially less costly and may therefore be the most cost‐effective of the three treatment conditions; however, small sample sizes limit our ability to reach definitive conclusions. Policy simulations suggest that implementing these interventions could raise the overall cost‐effectiveness of Head Start by at least 16 percent.  相似文献

Over the past decade, directional drilling and hydraulic fracturing enabled an unconventional oil and gas extraction (UOGE) boom in many regions of the United States, including parts of Pennsylvania. This revolution has created serious concerns about the capability of existing institutions to govern important societal outcomes associated with UOGE. We present a conceptual framework for assessing key societal outcomes influenced by UOGE governance. In applying this framework to Pennsylvania, we discern certain institutional strengths that have allowed the Commonwealth to reap appreciable short‐term economic growth from rich resource endowments. We also find, however, that several institutional weaknesses have allowed costs externalized to the environment, public health, and community integrity to offset some proportion of those economic benefits. Likewise, we find that governance of UOGE in Pennsylvania has contributed to a bifurcated sociopolitical landscape wherein adversarial coalitions dispute the legitimacy of the industry and its governance.  相似文献

We use a natural experiment to study how the announcement of the UK COVID-19 lockdown affected citizens' attitudes towards the pandemic and the government's response to it. On the day of the lockdown announcement, YouGov ran a survey that captured responses before and after the announcement. Comparison of these responses suggests that the lockdown announcement made people more supportive of the government's response to the crisis but also (perhaps surprisingly) more concerned about the pandemic. Analysis of heterogeneous treatment effects suggests that the announcement narrowed gaps in perceptions of the crisis, increasing support for the government's response especially among those who had been least supportive and increasing concern about the pandemic especially among those who had been least concerned. Overall, the findings highlight a tension inherent in governing during times of crisis: actions that increase people's confidence in government and induce compliance with government directives may also tend to increase anxiety among the population.  相似文献

The 11 September attacks cannot be understood fully without an understanding of the ideas of Sayyid Qutb, who is widely acknowledged as the intellectual godfather for the various modern radical Islamic movements, including Al-Qaeda. Qutb's writings are important because they define the core elements that have been adopted by all radical Islamic movements. These include: (1) an extreme hostility toward Western culture, especially the role of women and sexual mores in the West; (2) the formation of society under the rule of Sharia, Islamic law; (3) the overthrow of governments not under the rule of Sharia by means of holy war; and (4) an intense hatred of Jews and distrust of Christians. This article also illustrates Qutb's influence on radical Islamic groups.  相似文献

Steadily increasing costs in hospitals and other health care facilities have been of increasing concern to government agencies and the public alike. In recent years state legislatures and state cost review boards have acted to control these ever-escalating costs. The role played by these third parties in the collective bargaining process, the impact of cost control laws and regulations, and the constraints thus imposed upon the parties directly involved are the subjects of this thought-provoking article.  相似文献
