Purpose – The purpose of this paper is to investigate the influences of natural content, food safety concern, health consciousness, and subjective knowledge on attitudes towards organic food and purchase intentions. Design/methodology/approach – Samples are collected in Taiwan from April to May 2014 with a total of 252 returned effective questionnaires. The data are analyzed by structural equation modeling. Findings – The results show that food safety concern and subjective knowledge have a significantly positive impact on attitudes towards organic food and purchase intentions, and natural content has a significantly positive effect on attitudes towards organic food. Moreover, it also shows that health consciousness and attitudes towards organic food have a significantly positive effect on purchase intentions. This study has found that subjective knowledge of organic food, health consciousness, and food safety concern are important factors impacting organic food purchase intentions. Practical implications – This study provides organic industry to understand the consumer’s demand from the consumers’ perspective and as a basis for the future development of organic food. Originality/value – The study results will provide a reference for the agricultural department of the government and the organic food promotion and education of organic food producers.

Purpose The purpose of this paper is to investigate whether there is a significant difference in consumer’s attitude and purchase intentions toward organic food and conventional food (non-organic food and non-genetically modified) under the influence of corporate social responsibility (CSR) for environmental protection in the context of global warming and frequent food safety issues. Design/methodology/approach To understand the triple bottom line(TBL) affect the consumers’ attitude and purchase intentions of organic food and conventional food from the consumer’s point of view, primary data collected via 363 valid questionnaires tested the conceptual model by structural equation modeling (SEM). Findings The results show that CSR has a significant influence on consumers’ perceived value. Moreover, perceived value is an important factor in affecting consumers’ attitude and purchase intentions. And consumers’ attitude toward environmental concern, food safety concern and CSR also have an indirect effect on purchase intentions. Originality/value The findings of the study would help corporations not only pursue economic profit but also keep a balance within the environment and the ecosystem, and serve as a reference to corporations to fulfill CSR for the goal of sustainable management.

A general concept is introduced featuring an ideal multifunctional surface that can avoid fouling problems while allowing the installed groups to perform with the high efficacy and accuracy necessary for delivering cascading and spontaneous biological activities. The idea is realized by using a direct synthesis of a multicomponent coating containing the two functionalities of 4‐methyl‐propiolate and 4‐N‐maleimidomethyl that is achieved via chemical vapor deposition copolymerization on various substrates. The novel coating can simultaneously perform specific bio‐orthogonal reactions, including the azide‐alkyne click reaction and a thiol‐maleimide coupling reaction. In the study, azide‐terminated polyethylene glycols are first immobilized on the methyl propiolate groups to impart an antifouling property, while bioactivity is enabled by tethering biotinylated thiols or Cys‐Arg‐Glu‐Asp‐Val (CREDV) peptides on the maleimide groups. The induced antifouling properties and bioactivities are confirmed by quartz crystal microbalance and cell culture studies. Finally, precisely manipulated endothelial cells, namely, human umbilical vein endothelial cells and bovine arterial endothelial cells, are observed on a complex stent substrate and on confined areas of the poly(methyl methacrylate) substrates.
