A single layer urban canopy model (SLUCM) with enhanced hydrologic processes, is evaluated in a tropical city, Singapore. The evaluation was performed using an 11 month offline simulation with the coupled Noah land surface model/SLUCM over a compact low-rise residential area. Various hydrological processes are considered, including anthropogenic latent heat release, and evaporation from impervious urban facets. Results show that the prediction of energy fluxes, in particular latent heat flux, is improved when these processes were included. However, the simulated latent heat flux is still underestimated by ∼40%. Considering Singapore's high green cover ratio, the tree evapotranspiration process is introduced into the model, which significantly improves the simulated latent heat flux. In particular, the systematic error of the model is greatly reduced, and becomes lower than the unsystematic error in some seasons. The effect of tree evapotranspiration on the urban surface energy balance is further demonstrated during an unusual dry spell. The present study demonstrates that even at sites with relatively low (11%) tree coverage, ignoring evapotranspiration from trees may cause serious underestimation of the latent heat flux and atmospheric humidity. The improved model is also transferable to other tropical or temperate regions to study the impact of tree evapotranspiration on urban climate.

Trust is the major driving force of an e-Consultation service adoption. When the disease is high in rarity, severity, or urgency, an off-line healthcare provider is less capable of providing meaningful, qualified, and immediate service. Therefore, there is a decreased positive effect of trust on the intention to use an e-Consultation service for those diseases.

The remanufacturing industry can realize sustainability by saving resources and protecting the environment. The remanufactured products have a high similarity with the new products, and how they affect consumers’ evaluation of the new products is an important issue. This paper discusses the relationship between the similarity of remanufactured products and consumers’ willingness to purchase new products, with a mediating effect of perceived quality and a moderating effect of brand reputation. The empirical analysis based on 498 valid samples shows our conclusions below. First, the similarity of remanufactured products has a significant negative impact on the purchase intention of new products. Second, the perceived quality of new products plays a partial mediating role between similarity and purchase intention. Third, brand reputation negatively moderates the relationship between the similarity of remanufactured products and the perceived quality of new products. Furthermore, brand reputation also moderates the mediating effect of the similarity of remanufactured products on the purchase intention of new products through the perceived quality of new products. This paper suggests a new perspective for the research of remanufactured products and provides an important reference for the healthy and sustainable development of recycling and remanufacturing industry.
