You Said, They Said: A Framework on Informant Accuracy with Application to Studying Self-Reports and Peer-Reports of Adolescent Smoking in China
Zoom Meeting 7:30 (EDT)
Social research heavily relies on self-reported data. However, it is known that self-reports, especially of sensitive behaviors, tend to be biased. Among many endeavors to address self-reporting bias, informants (such as peers, co-workers, and family members) are often employed to provide alternative reports to supplement self-reports. In this paper, I discuss the necessity and the applicability of using informant reports and the types, measures, and determinants of informant accuracy. I show that studying informant accuracy not only helps deepen our understanding regarding how perceptions of alters are configured, but also helps develop more effective methods to utilize informant reports to correct self-reporting bias. I also propose a general framework that links informant accuracy to informant characteristics as has been done in prior studies, but also to alter characteristics, dyadic characteristics, and features of the object being reported on. I illustrate the framework through a case study of self-reports and peer-reports of smoking among 4,094 middle school students in China. The results reveal mechanisms that can account for previous findings, present more nuanced patterns beyond previous findings, and show the distinctive logics for identifying the presence and the absence of a behavior.

Seventeen years after the SARS outbreak, with cities in lockdown and tens of thousands of patients in intensive care units in China because of the novel coronavirus (COVID-19) outbreak, disease prevention and control has again been put into spotlight, albeit unwanted. This presentation will discuss China’s disease control prevention systems, its evolution over time, and its key components and structure. I will also provide a comparison between the public health systems in China and that in the US, with a particular focus on the emergency preparedness and response. The presentation will offer some food for thought on China’s public health systems and policy recommendations.

Some 50 years after its conclusion, many aspects of China’s Cultural Revolution remain obscure, despite the fact that it ranked among the largest political upheavals of the 20th century. Perhaps the most puzzling is the two years of armed warfare between rebel factions that spread across China after a wave of rebel power seizures overthrew local governments in early 1967. Official sources indicate that some 250,000 people died in battles between civilian factions during this period, and another 1.3 million died in political campaigns and military operations to suppress the fighting and restore order. This talk provides an evidence-based overview of these conflicts, based on information extracted from 2,246 local histories published in China since the late 1980s. It addresses two puzzling features of this poorly understood period of recent Chinese history: why did antagonistic factions form, and why did violence break out and prove so difficult to suppress?
