  • 简介:有关农业,农民,和农村区域处理这些问题,中国的中央政府开始了在2005称为新农村建设的新策略。为更好理解它的实际效果,这份报纸在Bohai边界区域(BRR)从586个家庭基于Kruskal-WallisH测试和采样调查数据分析对这新农村构造策略的农民家庭反应的地区性的差异,长江三角洲区域(YDR),并且平底锅珀尔河三角洲区域(PPR)。结果显示在东方沿海的中国(ECC)的那地区性的差异确实在公认的优先级顺序,政策要求,期望的政策效果,和行为反应形式存在。由于在本地政策实践和家庭之间的偏差固有的需求,农民们经由个人完成他们的事实上的需求而不是政府帮助,并且因此,新农村构造没能执行期望的目标的努力。它因此需要转移当前的政策优先级,保证农民支柱角色,并且提出新农村建设的科学规则。

  • 简介:AbstractBackground:Despite the recent advances in treatments for rheumatoid arthritis (RA), there are still unmet needs in disease outcomes. This study aimed to analyze the satisfaction with drug therapies for RA according to the levels of disease severity (patientassessed) and proportions of treatment cost to household income.Methods:This was a subgroup study of a cross-sectional study in patients with RA and their physicians. The patients were subdivided into different subgroups based on their self-assessed severity of RA and on the proportions of treatment cost to household income (<10%, 10-30%, 31-50%, and >50%). The Treatment Satisfaction Questionnaire for Medication version II was used to assess patients’ treatment satisfaction.Results:When considering all medications, effectiveness, convenience, and global satisfaction scores were lower in the severe and moderate RA subgroups than those in the mild and extremely mild RA subgroups (all P < 0.001). Effectiveness, side effects, and convenience scores were higher in the <10% subgroup compared to those in the >50% subgroup (all P < 0.05). Global satisfaction score was higher in the <10% subgroup than that in the 31% to 50% subgroup (F = 13.183, P = 0.004). For biological diseasemodifying anti-rheumatic drugs, effectiveness and convenience scores were lower in the severe RA subgroup than those in the extremely mild RA subgroup (both P < 0.05). Convenience score was higher in the <10% subgroup compared to that in the 31% to 50% and >50% subgroups (F = 12.646, P = 0.005). Global satisfaction score was higher in the <10% subgroup than that in the 31% to 50% subgroup (F = 8.794, P = 0.032).Conclusion:Higher disease severity and higher financial burden were associated with lower patient satisfaction.
