Consumer food waste linked to restaurants and canteens has been a long-standing serious problem in China, which hungers for an effective solution. Although government and media have launched campaigns against food waste, limited information on consumer perceptions is provided in helping to guide campaign programs. The influence of perception associated with low food waste is lacking, along with targeting campaigns based on these perceptions. This research aims to fill this gap. The purpose of this paper is to identify consumption perceptions about food waste in the Chinese urban restaurant sector, so that they can be used in social marketing to promote food waste reduction behaviors. Employing Probit models using survey data collected, we found that food security and environmental perceptions are associated with low food waste. Campaigns directed toward reducing food waste should target raising awareness of food security alert and environmental concerns that are more generally appealing to altruistic spirits.

OBJECTIVES: We evaluated the performance of the Elecsys HIV combi PT assay on the cobas e 602 analyzer for diagnosing human immunodeficiency virus (HIV; part of the US Food and Drug Administration [FDA] submission). METHODS: The HIV combi PT and reference (ARCHITECT HIV Ag/Ab Combo) assays were assessed at four independent clinical laboratories/one reference laboratory (United States; July 2014 to November 2015). Clinical performance was evaluated using four reagent lots. Analytical performance was evaluated per Clinical and Laboratory Standards Institute EP05-A3 guidelines. Serum/plasma samples from 18 clinical sites/vendors (United States and outside the United States) were tested. RESULTS: Sensitivity (95% confidence interval [CI]) in HIV-1 antibody-positive individuals (United States and outside the United States; n = 1,460) was 100.00% (99.75%-100.00%). Specificity was 99.94% (95% CI, 99.85%-99.98%) in low-risk individuals (United States; n = 6,843), 98.19% (95% CI, 96.93%-99.04%) in high-risk individuals (United States and outside the United States; n = 758), and 97.43% (95% CI, 95.32%-98.76%) in pregnant women (United States and outside the United States; n = 440). Analytical performance was acceptable. CONCLUSIONS: We demonstrate the robustness of the FDA-approved Elecsys HIV combi PT assay on the cobas e 602 analyzer for HIV testing in the United States.
