“…It is possible that interviewees who had difficulty recalling with whom they discussed changes may have defaulted to naming leaders because this was a culturally expected response (Bernard et al 1984). However, in spite of problems with any single interviewee's recall accuracy, people who were named the Ecology and Society 21(1): 25 http://www.ecologyandsociety.org/vol21/iss1/art25/ most frequently across all interviews are likely to be the people who were most sought out in the network in reality (Bernard et al 1982).…”

“…Accordingly, estimates of racial preferences may be biased downward. A second bias, potentially compounding the first, is that individuals often have inaccurate beliefs about their own preferences (Gilbert 2006;Bernard et al 1984;Nisbett and Wilson 1977). Thus even survey tools that are designed to correct for social desirability bias may underestimate preferences for same-race partners for the simple reason that respondents believe themselves to be more race-blind than they actually are.…”

Abstract:What explains the relative persistence of same-race romantic relationships? One possible explanation is structural-this phenomenon could reflect the fact that social interactions are already stratified along racial lines-while another attributes these patterns to individual-level preferences. We present novel evidence from an online dating community involving more than 250,000 people in the United States about the frequency with which individuals both express a preference for same-race romantic partners and act to choose same-race partners. Prior work suggests that political ideology is an important correlate of conservative attitudes about race in the United States, and we find that conservatives, including both men and women and blacks and whites, are much more likely than liberals to state a preference for same-race partners. Further, conservatives are not simply more selective in general; they are specifically selective with regard to race. Do these stated preferences predict real behaviors? In general, we find that stated preferences are a strong predictor of a behavioral preference for same-race partners, and that this pattern persists across ideological groups. At the same time, both men and women of all political persuasions act as if they prefer same-race relationships even when they claim not to. As a result, the gap between conservatives and liberals in revealed same-race preferences, while still substantial, is not as pronounced as their stated attitudes would suggest. We conclude by discussing some implications of our findings for the broader issues of racial homogamy and segregation.

To help health policy makers gain response time to mitigate infectious disease threats, it is essential to have an efficient epidemic surveillance. One common method of disease surveillance is to carefully select nodes (sentinels, or sensors) in the network to report outbreaks. One would like to choose sentinels so that they discover the outbreak as early as possible. The optimal choice of sentinels depends on the network structure. Studies have addressed this problem for static networks, but this is a first step study to explore designing surveillance systems for early detection on temporal networks. This paper is based on the idea that vaccination strategies can serve as a method to identify sentinels. The vaccination problem is a related question that is much more well studied for temporal networks. To assess the ability to detect epidemic outbreaks early, we calculate the time difference (lead time) between the surveillance set and whole population in reaching 1% prevalence. We find that the optimal selection of sentinels depends on both the network’s temporal structures and the infection probability of the disease. We find that, for a mild infectious disease (low infection probability) on a temporal network in relation to potential disease spreading (the Prostitution network), the strategy of selecting latest contacts of random individuals provide the most amount of lead time. And for a more uniform, synthetic network with community structure the strategy of selecting frequent contacts of random individuals provide the most amount of lead time.
