Customer orientation of salespeople usually leads to a sustainable positive effect on job performance, yet previous research has usually focused on the benefits of functional customer orientation, and less is known about its relational customer orientation’s outcomes. Based on conservation of resources theory, this research focuses on both types of customer orientation, functional and relational customer orientation, and investigates the moderating effect of emotional exhaustion on the relationship between customer orientation and adaptive selling behavior. We collected 282 valid questionnaires from frontline salespeople in China. Results showed that functional/relational customer orientation was positively correlated with salespeople’s adaptive selling behavior. Salespeople’s emotional exhaustion moderates the main effect: when emotional exhaustion is high, the relationship between functional/relational customer orientation and adaptive selling behavior is substantially weakened. This study contributes to a further understanding of the sustainable operation environment for customer orientation, and provides practical implications regarding the attainment of sustainable outcomes of customer orientation.

Double skin facades (DSFs) have gained increasing popularity worldwide for potential building energy savings. Such energy advantages are widely thought to be attributed to the ventilation feature of the DSF cavity. Keeping the cavity open to the outside, however, practically causes noise problems, dust pollution, and safety issues and thereby raising the maintenance cost of DSFs. This paper attempted to bring up this issue for more attention. We first numerically examined the thermal performance of DSF windows based on the climate of Hangzhou City featured by hot summer (>30℃) and cold winter (~4℃). Then we discussed the potential energy benefits of DSFs and the ventilation design of the cavity. Results from our simulations showed that the DSF window was more energy efficient than a double glazing window in summer regardless of the cavity open or closed. Such energy advantages were more due to the additional pane of the DSF window to reduce the solar transmittance than due to ventilation of the cavity. Although ventilation is beneficial in summer, the annual energy gain may be limited. Our simulations showed that ventilation can save annual energy by no more than 8% under Hangzhou climatic conditions. Therefore, to justify the use of ventilation in a DSF, we recommend a comprehensive evaluation to be performed by balancing the annual energy gains and investment increase associated with the open cavity.

Given this backdrop, understanding how to achieve the effectiveness of health ads is of importance. To vividly show product efficacy, marketers attempt to exhibit the change that products bring. A change ad, which is widely used in the marketplace, is defined as an ad that shows the corresponding changes delivered by a health product (or service). A change ad can be classified as either a progression ad or a before/after ad (Cian et al., 2020). For instance, when highlighting the changes that occur after orthodontic treatment, a progression ad will present the state of the teeth that range from irregular (before) to slightly aligned (intermediate) and finally to perfectly aligned (after), while a before/ after ad will only compare irregularly aligned teeth (before) with perfectly aligned teeth (after). Other health persuasions (e.g., weight-loss programs, acne treatments, hair-growth treatments, and teeth-whitening products) could be also promoted through change ads to emphasize product efficacy.Recent research has documented that compared with before/after ads, progression ads are more likely to encourage consumers to engage in process simulation spontaneously and therefore make the ads more credible and persuasive (Cian et al., 2020).
