Prevention of Cataract Blindness in Rural China.

China has undergone dramatic economic and social reforms during last 30 years, leading to a notably higher level of living standards and health care access for Chinese citizens. However, China's cataract surgical rate of 780 cases/y per million population trails Asian neighbors with lower income levels such as India and Vietnam. Eye care providers and patients encounter many barriers in gaining access to one another.Hands-on training programs conducted by international nongovernmental organizations and the government have helped to increase the number of qualified cataract surgeons in rural area, but establishing a residency training system that produces ophthalmologists capable of performing independent surgery is the only sustainable way to meet the increasing demand for surgery from an aging population. The New Rural Cooperative Medical System has successfully reduced the financial burden of cataract surgery for the rural population; however, reimbursement for outpatient treatment of leading eye diseases is needed.Community outreach screening combined with education is essential in rural areas' increased demand for surgery. Methods to optimize the yield from such screening must still be devised and proven, however. Improvements in the hospital administration and management structure are also needed to improve the efficiency of China's rural hospitals in delivering high-quality, low-cost cataract surgical services.

Parallel Time Series Analysis and Income Inequality: A New Approach to Comparative Case Studies

This case study deals with the role of time series analysis in sociology, and its relationship with the wider literature and methodology of comparative case study research. Time series analysis is now well-represented in top-ranked sociology journals, often in the form of ‘pooled time series’ research designs. These studies typically pool multiple countries together into a pooled time series cross-section panel, in order to provide a larger sample for more robust and comprehensive analysis. This approach is well suited to exploring trans-national phenomena, and for elaborating useful macro-level theories specific to social structures, national policies, and long-term historical processes. It is less suited however, to understanding how these global social processes work in different countries. As such, the complexities of individual countries - which often display very different or contradictory dynamics than those suggested in pooled studies – are subsumed. Meanwhile, a robust literature on comparative case-based methods exists in the social sciences, where researchers focus on differences between cases, and the complex ways in which they co-evolve or diverge over time. A good example of this is the inequality literature, where although panel studies suggest a general trend of rising inequality driven by the weakening power of labour, marketisation of welfare, and the rising power of capital, some countries have still managed to remain resilient. This case study takes a closer look at what can be learned by applying the insights of case-based comparative research to the method of time series analysis. Taking international income inequality as its point of departure, it argues that we have much to learn about the viability of different combinations of policy options by examining how they work in different countries over time. By taking representative cases from different welfare systems (liberal, social democratic, corporatist, or antipodean), we can better sharpen our theories of how policies can be more specifically engineered to offset rising inequality. This involves a fundamental realignment of the strategy of time series analysis, grounding it instead in a qualitative appreciation of the historical context of cases, as a basis for comparing effects between different countries.

Sexual abuse of children in low-income settings:time for action

In this article, child sexual abuse in low-income settings is reviewed, including the extent of the problem, the way children present, and how they should be managed. Liaising with other agencies, training in all aspects of sexual abuse and creating an environment that is conducive to good care by all groups involved is essential. Technical details of medical examination are not covered as appropriate guidelines are accessible.
