“…Therefore, we adjust the sampling weights using post-stratification to improve the representativeness of our sample 12 . Post-stratification is commonly used in sample surveys with the goal of helping to reduce the bias and variance of estimates; readers who are interested in learning more about post-stratification can consult standard survey research texts (e.g., Särndal and Lundström 2005;Lumley 2011;Valliant et al 2013). We provide a conceptual overview of how we used post-stratification here.…”

Online data sources offer tremendous promise to demography and other social sciences, but researchers worry that the group of people who are represented in online data sets can be different from the general population. We show that by sampling and anonymously interviewing people who are online, researchers can learn about both people who are online and people who are offline. Our approach is based on the insight that people everywhere are connected through in-person social networks, such as kin, friendship, and contact networks. We illustrate how this insight can be used to derive an estimator for tracking the digital divide in access to the Internet, an increasingly important dimension of population inequality in the modern world. We conducted a large-scale empirical test of our approach, using an online sample to estimate Internet adoption in five countries (n ≈ 15,000). Our test embedded a randomized experiment whose results can help design future studies. Our approach could be adapted to many other settings, offering one way to overcome some of the major challenges facing demographers in the information age.Electronic supplementary materialThe online version of this article (10.1007/s13524-019-00840-z) contains supplementary material, which is available to authorized users.

“…Constructing a sample is, in most ways, not much different in a mobile phone survey relative to other surveys, and many of the same resources are useful. Readers who would like to explore in greater depth the issues discussed in this chapter might consult, for example, Survey Sampling (Kish 1965), Methodology of Longitudinal Surveys (Lynn 2009), and Practical Tools for Designing and Weighting Samples (Valliant, Dever, and Kreuter 2013).…”

“…In order to calculate the effective sample size when considering other type of sampling schemes than the simple random sampling has been extensively studied. Several authors have studied how to adjust the sample size calculation according to the type of design used (Kish, 1965(Kish, , 1990(Kish, , 1992Spencer, 2000;Valliant et al, 2013Valliant et al, , 2015. For the calculation of the effective sample size (n eff ), we have used the proposed approached by Gabler et al (1999) in which the actual sample size is divided by the design effect (d eff ).…”

“…According to the above-mentioned surveillance scheme, data about sampling of herds in each d epartement and the number of animals sampled in each herd were obtained for 33 French d epartements, where there is sentinel surveillance. These data were used to explore the achievable design prevalence with 95% confidence interval according to Valliant et al (2013). A curve was drawn for the worst-and best-case scenario at NUTS 3 level (corresponding to the French d epartement) considering the amount of farms and animal sampled within a farm in each d epartement (Figures 13-14) and for the scenario at national level ( Figure 15).…”

Bluetongue: control, surveillance and safe movement of animals

The performance of different bluetongue control measures related to both vaccination and protection from bluetongue virus (BTV) vectors was assessed. By means of a mathematical model, it was concluded that when vaccination is applied on 95% of animals even for 3 years, bluetongue cannot be eradicated and is able to re-emerge. Only after 5 years of vaccination, the infection may be close to the eradication levels. In the absence of vaccination, the disease can persist for several years, reaching an endemic condition with low level of prevalence of infection. Among the mechanisms for bluetongue persistence, the persistence in the wildlife, the transplacental transmission in the host, the duration of viraemia and the possible vertical transmission in vectors were assessed. The criteria of the current surveillance scheme in place in the EU for demonstration of the virus absence need revision, because it was highlighted that under the current surveillance policy bluetongue circulation might occur undetected. For the safe movement of animals, newborn ruminants from vaccinated mothers with neutralising antibodies can be considered protected against infection, although a protective titre threshold cannot be identified. The presence of colostral antibodies interferes with the vaccine immunisation in the newborn for more than 3 months after birth, whereas the minimum time after vaccination of animal to be considered immune can be up to 48 days. The knowledge about vectors ecology, mechanisms of over-wintering and criteria for the seasonally vector-free period was updated. Some Culicoides species are active throughout the year and an absolute vector-free period may not exist at least in some areas in Europe. To date, there is no evidence that the use of insecticides and repellents reduce the transmission of BTV in the field, although this may reduce host/vector contact. By only using pour-on insecticides, protection of animals is lower than the one provided by vector-proof establishments.
