US Congress passed the CARE Act in 1990 in response to a dramatically growing need for resources to combat the AIDS epidemic. One of the programs contained in the Act was the AIDS Drug Assistance Program (ADAP), a federally-funded but state-maintained and managed program primarily concerned with providing medication for low-income HIV/AIDS patients. While ADAP programs across the country reached one-third of all patients in 2007, these programs are now in budgetary danger due to the economic recession, state budgetary constraints, the rising cost of healthcare generally, and longer life expectancies associated with current highly active antiretroviral therapy (HAART). This paper first evaluates the current state of ADAP, its strengths and weaknesses, and examines its sustainability in the short term if short-term measures are taken. Concluding that such measures would not lead to long-term sustainability, this paper then argues for a long-term solution to ADAP’s current problems, namely a national, centralized ADAP standard for budgetary and administrative matters. Such a program would increase the long-term sustainability and effectiveness of current ADAP programs by employing more efficient, standard policies and allowing larger, wholesale purchases of costly HAART medications. Moreover, a national policy would address the disparity that currently exists in ADAP programs today with regard to both minorities and those on the waiting lists for treatment. The institution of a national ADAP program would certainly face many political hurdles. Consequently, this paper also looks to a recent political dispute, the enactment of the Affordable Care Act (ACA), for guidance. Using the passage of the ACA as an example could light the path for passage of a national ADAP standard. Ultimately, this would lead to a more effective and sustainable program for HIV/AIDS patients in the United States. 展开更多

Continuously growing populations and rapid economic development have led to the excessive use of forest resources,and the forest ecosystem is threatened.In response,forest ecological security(FES)has attracted attention.In this study,an integrated dynamic simulation model was constructed using the system dynamic method,and it was used to evaluate the FES in China from 1999 to 2014.A scenario analysis was then used to evaluate the changes in the FES under five forestry policy scenarios for the 2015–2050 period,including the baseline,afforestation policy,harvesting policies,management policy,investment policy,and a policy mix.The results showed that the evaluation values of the FES increased during the period from 1999 to 2002,the period from 2004 to 2010 and the year 2014,and they decreased in 2003 and during the period from 2011 to 2013.During the 2015–2050 simulation period,the FES improved continuously.In particular,China would enter a new stage when the economic systems,social systems and ecosystems were in harmony after 2040.To improve the FES and the current status of the FES,a scenario analysis showed the most suitable scenario to be Scenario 5 from 2015 to 2020 and Scenario 2 from 2021 to 2050.To relieve pressure,the most suitable scenario would be Scenario 5 from 2015 to 2040 and from 2046 to 2050,and the most suitable scenario would be Scenario 4 for 2041–2045.A policy mix(Scenario 5)would be most efficient under current conditions,while the effects of all the benefits of the forestry policies would weaken over the long term.The integrated method can be regarded as a decision support tool to help policy makers understand FES and promulgate a reasonable forestry policy. 展开更多

Because that American government and congress hold a negative attitude on responding to climate change issue, people transfer the battle stage of climate change to the court,and hope to promote government and large energy companies actively responding to climate change issue via litigation form. A large amount of related litigation appears,and a kind of special litigation type is gradually formed, namely climate change litigation. National Environmental Policy Act of the United States is one of important legal weapons used by prosecutor in climate change litigation. In National Environmental Policy Act, it stipulates environmental impact evaluation system which has close relationship with climate change litigation. The system requires that federal agency " should compile detailed environmental impact report (EIS) on major federal action which significantly affects human survival environment quality". Litigation case of Export - Import Bank of the United States and Overseas Private Investment Corporation by Fdends of the Earth, Green Peace, Boulder City, etc. is typical one related to the act.

This study evaluated the impacts of food safety policies on Japan's Simultaneous Buy and Sell rice imports through measuring tariff equivalents of food safety policies.In order to construct an estimated model,a Japanese consumer's utility function is introduced and developed with consumer's preference parameters and elasticity of substitution.In the empirical study part,Japan's positive list system and rice traceability were analyzed and assessed as critical food safety policies.Results showed that after the implementation of the positive list system,consumers'preference for foreign rice and the substitution elasticity diminished.This decreasing tendency was quite similar to the results after the enforcement of rice traceability.The tariff equivalents of food safety policies on imported rice fluctuated around ¥50 yen/kg from fiscal year 2000 to 2005 and decreased because of the global grain price hike after 2006.The tariff equivalents soared in 2010,which was induced by the traceability regulation,and then dulled during Japan's earthquake and tsunami in 2011.Subsequently,after the recovery from natural disasters,the tariff equivalents of food safety policies became higher.Therefore,food safety policies had made imported rice less attractive,weakened the competitive power of rice exporting countries,and had statistically significant impacts on Japan's rice importation. 展开更多

This study explores the application of Bayesian econometrics in policy evaluation through theoretical analysis. The research first reviews the theoretical foundations of Bayesian methods, including the concepts of Bayesian inference, prior distributions, and posterior distributions. Through systematic analysis, the study constructs a theoretical framework for applying Bayesian methods in policy evaluation. The research finds that Bayesian methods have multiple theoretical advantages in policy evaluation: Based on parameter uncertainty theory, Bayesian methods can better handle uncertainty in model parameters and provide more comprehensive estimates of policy effects;from the perspective of model selection theory, Bayesian model averaging can reduce model selection bias and enhance the robustness of evaluation results;according to causal inference theory, Bayesian causal inference methods provide new approaches for evaluating policy causal effects. The study also points out the complexities of applying Bayesian methods in policy evaluation, such as the selection of prior information and computational complexity. To address these complexities, the study proposes hybrid methods combining frequentist approaches and suggestions for developing computationally efficient algorithms. The research also discusses theoretical comparisons between Bayesian methods and other policy evaluation techniques, providing directions for future research. 展开更多

It is essential to ensure that teachers allocate adequate attention to homework evaluation and effectively carry it out in order to successfully implement the"double reduction"policy.From the perspective of teachers'attention allocation,this study employed the NVivo 12 software to conduct text analysis on 39 cases of homework evaluation reform practices in primary and secondary schools in City N,China,from 2017 to 2021.The findings indicate that homework evaluation reform in these schools is a practical problem-oriented behavioral decision,and implementing the"double reduction"policy enhances teachers'attention allocation on homework evaluation.The attention allocation of teachers encompasses multiple aspects,such as determining the purpose of evaluation,setting evaluation content,and selecting evaluation subjects and methods.Following the implementation of the"double reduction"policy,teachers allocate more attention to reducing the homework burden on students.However,certain issues persist in the practices of homework evaluation reform,including inadequate consideration of constraints,an unbalanced content structure,and a lack of process coordination.Therefore,under the"double reduction"policy,it is imperative to improve school incentive systems,enhance teachers'evaluation capabilities,and alleviate their workload.These measures can guide teachers to allocate more attention to homework evaluation,thereby enhancing the efficiency and sustainability of attention allocation and fully realizing the educational function of homework evaluation. 展开更多

China has promulgated a series of policies including the Western Development Program, the Grain for Green Project, agricultural support policies and building a new countryside strategy to eliminate east-west differences and urban-rural disparities since the late 1990s. This paper gives a holistic examination on local responses to the four typical macro socio-economic development policies and their effects on rural system based on a case study of a mountainous village in southern Sichuan Province. The results showed that the policies have not moved the case study village from its historically marginal status. To some extent, its socio-economic situation might have been worsened by accelerated out- migration of the youth, loss of agricultural land due to afforestation and industrial plants, increased fire hazard due to afforestation and reforestation, increased environmental pollution due to industrial enterprises attracted to the village and a steep decline in agricultural production due to loss of and inefficient use of cultivated land. Factors causing local villages' dilemmas include the nonuniformity of actors' objectives, finiteness of villagers' abilities, and the imperfect incentive and restraint mechanism for local government's activities under existing policy framework composed of uncoordinated one-size-fits- all policies. We suggest that China's rural policy in the new period should gradually shift from a sectoral to a place-based one, from top-down incentives to the development of bottom-up projects, and fully recognize the diversity of rural space, so as to lift localcapacities and make good use of the knowledge shared by different actors. Moreover, it is also necessary to integrate the various sectoral policies, and improve the interministerial and interdepartmental coordination of rural policies at regional and local levels. 展开更多

Background:Despite the well-established health benefits of physical activity(PA)for young people(aged 419 years),most do not meet PA guidelines.Policies that support PA in schools may be promising,but their impact on PA behavior is poorly understood.The aim of this systematic review was to ascertain the level and type of evidence reported in the international scientific literature for policies within the school setting that contribute directly or indirectly to increasing PA.Methods:This systematic review is compliant with Preferred Reporting Items for Systematic Review and Meta-Analysis guidelines.Six databases were searched using key concepts of policy,school,evaluation,and PA.Following title and abstract screening of 2323 studies,25 progressed to data synthesis.Methodological quality was assessed using standardized tools,and the strength of the evidence of policy impact was described based on pre-determined codes:positive,negative,inconclusive,or untested statistically.Results:Evidence emerged for 9 policy areas that had a direct or indirect effect on PA within the school setting.These were whole school PA policy,physical education,sport/extracurricular PA,classroom-based PA,active breaks/recess,physical environment,shared use agreements,active school transport,and surveillance.The bulk of the evidence was significantly positive(54%),27%was inconclusive,9%was significantly negative,and 11%was untested(due to rounding,some numbers add to 99%or 101%).Frequency of evidence was highest in the primary setting(41%),34%in the secondary setting,and 24%in primary/secondary combined school settings.By policy area,frequency of evidence was highest for sport/extracurricular PA(35%),17%for physical education,and 12%for whole school PA policy,with evidence for shared use agreements between schools and local communities rarely reported(2%).Comparing relative strength of evidence,the evidence for shared use agreements,though sparse,was 100%positive,while 60%of the evidence for whole school PA policy,59%of the evidence for sport/extracurricular PA,57%of the evidence for physical education,50%of the evidence for PA in classroom,and 50%of the evidence for active breaks/recess were positive.Conclusion:The current evidence base supports the effectiveness of PA policy actions within the school setting but cautions against a“one-sizefits-all”approach and emphasizes the need to examine policy implementation to maximize translation into practice.Greater clarity regarding terminology,measurement,and methods for evaluation of policy interventions is needed. 展开更多

In communication networks with policy-based Transport Control on-Demand (TCoD) function,the transport control policies play a great impact on the network effectiveness. To evaluate and optimize the transport policies in communication network,a policy-based TCoD network model is given and a comprehensive evaluation index system of the network effectiveness is put forward from both network application and handling mechanism perspectives. A TCoD network prototype system based on Asynchronous Transfer Mode/Multi-Protocol Label Switching (ATM/MPLS) is introduced and some experiments are performed on it. The prototype system is evaluated and analyzed with the comprehensive evaluation index system. The results show that the index system can be used to judge whether the communication network can meet the application requirements or not,and can provide references for the optimization of the transport policies so as to improve the communication network effectiveness. 展开更多
