Tax Non-Compliance and Perceptions of Corruption: Policy Implications for Developing Countries

Tax non-compliance and perceptions of corruption are key challenges to state-building in developing countries. Using a social psychology approach, we develop a theoretical model in which different forms of perceived corruption can adversely influence the way individual taxpayers behave. We then apply this model to Indonesia, placing our empirical findings in the context of compliance risk management, identifying strategies to improve tax compliance, and exploring how to implement these strategies effectively. We shed light on the applicability of the traditional responsive regulatory approach (used by revenue authorities to deal with intentionally non-compliant taxpayers), which combines measures in attempting to achieve either voluntary or enforced compliance. While the empirical evidence is based on the Indonesian experience, we suggest that our model is sufficiently general and robust to be applicable to other developing countries in the Asia-Pacific region.     

肥城市养老服务机构发展状况的调查分析

通过实地考察和问卷调查相结合的方法,对山东省肥城市养老服务机构发展情况进行了调查分析。分析表明,肥城市的养老服务机构数量呈现先减后增的变化,形式主要有养老院、敬老院、日间照料中心和农村幸福院,床位提供充足,并引入了新型智能管理。但也存在一些不足之处,如养老服务机构职工的平均年龄偏大、学历较低,人员配备不足,培训效果较差,财政资金投入不足等。为此,应从养老服务机构的形式、质量、人员配备等方面进一步完善发展。     

新型城镇化背景下的产城融合发展思考

基于社会转型时局与产城融合理念的提出,从时间维度、空间格局、产业特征以及价值导向四大层面对新型城镇化背景下的产城融合理念进行再认识。在当前时代发展的大趋势之下,城市的发展应该逐步完成由物的城镇化向人的城镇化转型;由工业文明向生态文明转型;由功能主义过渡到人本主义继而朝多元共生的价值取向转型。未来阶段,“产”、 “城”间的融合会呈现出“产”、“城”、“人”、“境”、“文”多要素碰撞与融合的发展格局。     

The association between the severity of chronic kidney disease and medical costs among patients with type 2 diabetes

Aims: Examine healthcare costs across chronic kidney disease (CKD) stages for US patients with type 2 diabetes (T2D).

Materials and methods: IQVIA Real World Data Adjudicated Claims linked electronic medical records and insurance claims from January 1, 2012 through March 31, 2017 were used for this retrospective study. Adults diagnosed with T2D and comorbid CKD were included. General linear models incorporating splines were constructed, and information from these regressions were used to inform the relationship between medical costs and CKD. Multivariable analyses controlled for patient characteristics, vital signs, general health, prior medication use, prior visit to specialists, index A1c, and year of index date.

Results: There were 6,645 individuals who met the study criteria. Results generally indicate sharp increases in annual total medical costs and non-drug medical costs in the 1?year post-period for patients with Stage 4 or 5 CKD (estimated glomerular filtration rate [eGFR]?≤?30?mL/min/1.73 m²) with each 1 point reduction in eGFR from 30 associated with an increase of $1,870 in all-cause total medical costs (p?<?0.0001) and $1,805 of all-cause non-drug medical costs (p?<?0.0001). Similarly, each point decline below 30?mL/min was associated annual cost increases of $1,701 for CKD-related total medical costs, $1,695 for CKD-related non-drug medical costs, $173 for diabetes-related medical costs, and $187 for diabetes-related non-drug medical costs (all p?<?0.0001).

Limitations: The investigation included only patients with medical insurance and laboratory test results, and results may not be generalizable to all T2D patients with CKD. The methodology allowed us to determine associations, not causation, and potential confounders, such as duration of diabetes, diet, exercise, or social support, could not be assessed.

Conclusions: Results indicate there are sharp and significant increases in medical costs among T2D patients with Stage 4 and 5 CKD compared to those with earlier stages of CKD.
