Spatial distribution of water supply reliability and critical links of water supply to crucial water consumers under an earthquake

This paper describes a process to characterize spatial distribution of water supply reliability among various consumers in a water system and proposes methods to identify critical links of water supply to crucial water consumers under an earthquake. Probabilistic performance of water supply is reflected by the probability of satisfying consumers’ water demand, Damage Consequence Index (DCI) and Upgrade Benefit Index (UBI). The process is illustrated using a hypothetical water supply system, where direct Monte Carlo simulation is used for estimating the performance indices. The reliability of water supply to consumers varies spatially, depending on their respective locations in the system and system configuration. The UBI is adopted as a primary index in the identification of critical links for crucial water consumers. A pipe with a relatively large damage probability is likely to have a relatively large UBI, and hence, to be a critical link. The concept of efficient frontier is employed to identify critical links of water supply to crucial water consumers. It is found that a group of links that have the largest UBI individually do not necessarily have the largest group UBI, or be the group of critical links.     

基于消费者感知的面料材质感官意象研究

以消费者为中心的设计是一种确保设计符合目标消费者的期望的方法。设计越来越注重消费者的感官体验,通过消费者感官意象的研究,创造出一种吸引消费者感官特性的设计方式,已成为现在设计的主要核心。本研究以面料材质为研究对象,选取代表性的材质样本,调查消费者的感官意象,确立感官意象的材质特性。研究中使用多种方法整合进行面料材质的消费者感官意象研究,使用多维尺度分析法构建消费者认知图,发现五种材质族群;通过因素分析法汲取消费者材质意象主因素,获得四种主因素;通过回归分析法获得材质族群对应的意象特征。研究结果为以消费者为中心的设计方法提供有价值的设计参考。     

Asians’ Facial Responsiveness to Basic Tastes by Automated Facial Expression Analysis System

Growing evidence shows that consumer choices in real life are mostly driven by unconscious mechanisms rather than conscious. The unconscious process could be measured by behavioral measurements. This study aims to apply automatic facial expression analysis technique for consumers’ emotion representation, and explore the relationships between sensory perception and facial responses. Basic taste solutions (sourness, sweetness, bitterness, umami, and saltiness) with 6 levels plus water were used, which could cover most of the tastes found in food and drink. The other contribution of this study is to analyze the characteristics of facial expressions and correlation between facial expressions and perceptive hedonic liking for Asian consumers. Up until now, the facial expression application researches only reported for western consumers, while few related researches investigated the facial responses during food consuming for Asian consumers. Experimental results indicated that facial expressions could identify different stimuli with various concentrations and different hedonic levels. The perceived liking increased at lower concentrations and decreased at higher concentrations, while samples with medium concentrations were perceived as the most pleasant except sweetness and bitterness. High correlations were founded between perceived intensities of bitterness, umami, saltiness, and facial reactions of disgust and fear. Facial expression disgust and anger could characterize emotion “dislike,” and happiness could characterize emotion “like,” while neutral could represent “neither like nor dislike.” The identified facial expressions agree with the perceived sensory emotions elicited by basic taste solutions. The correlation analysis between hedonic levels and facial expression intensities obtained in this study are in accordance with that discussed for western consumers.     

To meat or not to meat? Comparing empowered meat consumers’ and anti-consumers’ preferences for sustainability labels

An increasing awareness of the impact of high levels of meat consumption on health and environmental sustainability is leading to a growing number of consumers reducing or avoiding meat. To address gaps in the literature, we compare and contrast the importance of the seven sustainability-related labels for three consumer groups (meat eaters, meat reducers and vegetarians) using a choice experiment involving 600 UK respondents (200 meat eaters, 200 meat reducers, 200 vegetarians). Type of meat, price and fat content labels have the largest overall impact on consumer choices. The impact of carbon footprint, method of production, origin and brand labels varies across consumer groups.We subsequently use latent class analysis to identify heterogeneous intra-group consumer segments, based on their preferences, and highlight the socio-demographic differences between them. For meat eaters, three consumer segments are identified (empowered, traditional and price conscious meat eaters). Meat reducers are divided into health curtailers and sustainable consumers, while only one segment of vegetarians is identified. By drawing on signalling theory and the consumer empowerment and anti-consumption literature, we identify links between sustainable consumption, consumer empowerment and anti-consumption and provide valuable insights for policymakers and practitioners seeking to utilise food labels to encourage more sustainable consumption.     

The Impact of Image Dimensions toward Online Consumers’ Perceptions of Product Aesthetics

Marketers and industrial designers devote considerable attention to the visual attributes of products, based on the premise that the visual appearance of products influences consumers’ judgments of the products’ attributes. This research investigated consumers’ perceptions about particular types of innovative products (revolutionary technology‐driven products), with 275 consumers sample purchased from an independent marketing company. To achieve the main goal, interrelations among image of product and aesthetics of product have been examined using structural equation modeling with two psychological moderators: consumer innovativeness and needs for uniqueness. The results of this study provide evidence that individual differences in uniqueness motivation moderated how online consumers’ perceptions of a product's image characteristics influenced perceptions of value showing consumers’ need for uniqueness was more influential toward perceptions of the product's value than perceptions of functional value. Consequently, these findings expand understanding of the consumer characteristics that respond to perceptions of products’ epistemic value.
