The effects of social media on online consumer behavior
Does social media have an effect on online consumer behavior? Because social media is now used to market many companies, brands, and products, this study provides data that will conclude if social media has a major effect on online consumer behavior. The purpose of this study is to interview consumers to see what their opinions are on social media and its effect on their online shopping experience. The study will give us a better understanding of how online consumers view and use social media.(Author abstract)Dobek, M., Toland, B., Gendron, R., Kitsios, A., and Stitt, R. (2014).

Diagnostic accuracy of methods for detecting Anaplasma marginale infection in lactating dairy cattle of Puerto Rico
Bovine anaplasmosis (BA) is a hemoparasitic disease of great importance in cattle within the
tropical and subtropical regions of the world. Control programs for BA require accurate diagnostic assays but
validation can be challenging because the true disease status of all animals is frequently not known with
certainty. The objective of this study was to estimate the accuracy of assays for detection of Anaplasma
marginale infection in lactating dairy cattle of Puerto Rico using Bayesian methods without a perfect reference
test. There were 2,331 cattle with complete diagnostic results sampled from 79 herds, and the prevalence of BA
was estimated as 22% (95% probability interval [PI]: 19–25%). The sensitivity (Se) and specificity (Sp) of a
major surface protein 5 competitive enzyme-linked immunosorbent assay (MSP-5 cELISA) were estimated as
99% (95% PI: 96–100%) and 89% (95% PI: 87–92%), respectively. The Se and Sp of a quantitative polymerase
chain reaction (qPCR) were 67% (95% PI: 60–74%) and 99% (95% PI: 99–100%). The Se and Sp of a card
agglutination test were 34% (95% PI: 29–39%) and 99% (95% PI: 99–100%). Area under the receiveroperating
characteristic curve for the MSP-5 cELISA was 0.748 (95% PI: 0.71–0.79). The MSP-5 cELISA
appears to be the test of choice for screening cattle for subclinical BA based on the high estimated Se, rapidity
of results, relative low cost, and ease of standardization
