Following a service failure, dissatisfied customers increasingly turn to brands’ social media outlets (e.g., Facebook brand page) to share their complaint with the involved company and other consumers. The majority of these other consumers (i.e., ‘recovery bystanders’) chooses to remain passive by simply observing the negative comment and the company’s attempt to restore the customer-brand relationship in public by means of ‘webcare’ (i.e., marketers’ communicative responses to online complaints (MIW); van Noort & Willemsen, 2011). For these observers the online service recovery process conveys valuable information for making purchase decisions. On the other hand, some consumers choose to become active, for instance, by making comments on the complaint or the company’s response and/or by ‘liking’ a comment (i.e., positive (brand-supportive) and negative (brand-unsupportive) ‘interactive virtual presence’ (IVP)). Given this interactive environment, recovery bystanders are exposed to strong social influence. Although recent research made some progress (e.g., Weitzl & Hutzinger, 2017), knowledge about the impact of this complex, social environment on recovery bystanders’ brand-related reactions remains scarce. In this study, we suggest that recovery bystanders’ level of susceptibility to normative influence (SNI) moderates the effect of different forms of webcare responses – accompanied by positive/negative IVP – on brand image. In 3 experiments (n = 1,387 consumers) we systematically manipulate response sources (i.e. ‘advocate-initiated webcare’ (AIW) vs. ‘marketer-initiated webcare’ (MIW)) and response types (study 1); interactive virtual presence via comments (positive IVP and negative IVP) (study 2) and Facebook ‘likes’ (positive IVP) (study 3). In explaining bystanders’ post-recovery evaluation of brand image we show that: Low-SNI bystanders, receiving AIW, as compared to MIW, show – regardless of webcare’s content – a significant increase. High-SNI bystanders, receiving AIW in the form of ‘vouching’ (i.e. an advocate counters a complaint with a ‘brand love story’) has the most pronounced effect – adding positive IVP (with additional, positive brand comments) even leads to a further improvement. However, adding negative IVP (with unfavorable brand comments) to marketer’s vouching reduced high-SNI bystanders’ image evaluation. Finally, when high-SNI bystanders receive advocate’s vouching and highly positive IVP (i.e., many ‘likes’), brand image evaluations significantly increase. This research draws scholars’ and practitioners’ attention to the opportunities – and perils – of cocreated service recoveries via social media.

As the transportation sector accounts for approx. 30% of energy consumption in Germany, a gradual increase in the number of electric vehicles (1 million should be operating by 2020) can make a significant contribution to road transportation sustainability. We need to plan and construct multi-functional infrastructure corridors to accelerate the introduction of electric vehicles. These not only include the actual transportation infrastructure, but equipment for obtaining energy (solar power units and wind turbines) and the necessary recharging systems (charging points, places and lanes). Zwickau University of Applied Sciences has conducted a feasibility study to mathematically calculate the technical design criteria and energy balance (energy requirements/output) along a section of highway, depending on the electric car quota, the section’s parameters and various energy generation scenarios; this involved driving simulation and real driving experience. The experiment results clearly show that, when designing transportation infrastructure, it makes sense to plan so-called multi-functional infrastructure corridors, which enable independent energy production, parallel energy distribution through cables and directly supplies from the recharging infrastructure. The real transportation infrastructure must develop from a simple to an intelligent roadway. The road standards must take into account the new requirements for alignment and cross-section design. Zwickau University has developed a new methodology for planning and designing multi-functional infrastructure corridors. It generates them with computer support, taking into account points of constraint. Genetic algorithms serve as the mathematical model. Pilot scheme results show that it will be possible to transfer this process to engineering offices in the near future.

Highly developed, European industrial countries normally have a dense network of rural highways. The future focus of roadwork in Germany, where there is a high density of 1.6 km of rural highway per km² of land, will involve upgrading and rebuilding rural highways prone to accidents. As new guidelines are not completely relevant for upgrading existing highways and exceptional permits are often required, there is an increasing need to use simulation in the design process to assess discrepancies from the standards and their effect on traffic safety. Using virtual driving (automatically using a defined driver profile or a driving simulator), it is possible to objectively assess expected driving behaviour using characteristic feature graphs and quantitative parameters derived from them. Zwickau University of Applied Sciences has developed a new multi-stage methodology for upgrading rural highways by using a 3D design working place simulator. The highway is automatically retraced using survey data and genetic algorithms in stage 1 (preliminary review) and is broken down into the horizontal and vertical projection design elements. Stage 2 involves determining the shortcomings on the road by superimposing the design elements, the actual accident figures and virtual driving runs. The actual replanning work occurs in stage 3, taking into account the minimum and maximum standard figures for the design elements. The replanning work is feasible, even if the standard figures are not met along parts of the route, but the graph figures, parameters and virtual driving runs prove that there is no reduction in traffic safety. Otherwise, the route needs to be realigned. After finishing the testing period of the hard- and software components, the methodology and the working place can be used from designing engineers for the preparing process of practical projects.

able to articulate their unfavorable opinions about products, brands and companies by posting complaints on a diverse set of platforms including the firms’ own Facebook brand pages. Such actions enable dissatisfied consumers to disseminate their negative sentiments among a broad audience of negative electronic word-of-mouth (NeWOM) observers (Hong & Lee, 2005). For those observers, negative consumer comments are a valuable source (Lee & Song, 2010). They usually read the NeWOM messages to identify the responsible party and to know what has caused other persons’ problems. This information, in turn, is likely to influence the potential customer’s own attitudes towards the company (e.g., Vermeulen & Seegers, 2009; Willemsen et al., 2011). Such inferences can have critical consequences for a company’s economic well-being. This study investigates how companies can counteract potential threats by means of corporate webcare (i.e., applying appropriate response strategies to counteract latent NeWOM effects). Previous studies focusing on the offline service management context have examined different types of corporate response strategies (e.g., Benoit, 1995; Coombs, 1999). Marcus and Goodman (1991), for instance, classify response strategies into either accommodative (i.e., the company accepts the failure and takes on responsibility for it) or defensive strategies (i.e., the company denies the responsibility for the negative event, attacks the accuser, or shifts the blame to others). In addition, no-action strategies are very popular among companies on the social web (Einwiller & Steilen, 2015; i.e., the company remains silent, makes only meaningless comments or takes no overt action). Furthermore, eWOM literature provides some evidence that consumers are more likely to listen to those who are not affiliated with the company (e.g., Colliander & Dahlén, 2011). On social media platforms, these brand advocates then defend a company from attacks by other consumers. The study at hand investigates the observer-related effects of multiple corporate- and consumer-response styles. More specifically, a one-factor between-subjects design (n = 728) manipulated different responses to a negative comment on a service failure publicized on a corporate Facebook fan page. Findings provide evidence that particularly accommodative online complaint handling can mitigate NeWOM effects and trigger favorable brand attitudes of NeWOM observers. Among alternative webcare strategies, empathetic communication including the acceptance of the failure and a simple public apology is an effective way to respond to negative Facebook comments. However, particularly responses including also an explanation as well as some kind of compensation can turn potential customers in actual customers of the brand. Findings further suggest that companies should perform their own webcare as defensive responses from brand advocates do not always leave a good impression. From a practical perspective, companies should consider webcare as a means not only to help current customers with their problems, but also to provide an outward-directed cue for the company’s customer-orientation.

The advances of the Internet open consumers new opportunities to share their consumption experiences, opinions and feelings with others. Online customer reviews (OCRs) are a crucial source of information for consumers and are regarded as one of the most influential types of electronic word-of-mouth (eWOM) in shaping consumer attitudes and facilitating purchase decisions (Plummer, 2007). Prior research has produced a number of valuable insights on OCRs (e.g., Dellarocas, Gao, & Narayan, 2010; Hennig-Thurau et al., 2004; Mayzlin, Dover, & Chevalier, 2014). Especially the influence of OCR valence (positively vs. negatively framed information) has received considerable attention both from practitioners and from scholars (e.g., Xue & Zhou, 2010; Yang & Mai, 2010; Lee et al., 2009). However, we argue that scientific insights on the influence of OCR valence remain limited. Specifically, this paper shows that the level of source credibility (high vs. low) as well as the type of product (search vs. experience good) are important moderators of the influence of OCR valence on several consumer OCR reactions (product attitude, product quality, and product trust) under specific circumstances only. Four hundred and sixteen respondents (70% females, average age 24 years) participated in an experiment with a 2×2×2 between-subjects full factorial design manipulating the OCR valence (positive vs. negative), the source credibility (high vs. low) and the product type (search vs. experience good). Results demonstrate that the effect of positive OCRs from highly credible sources on diverse outcome variables is larger than from low credible sources. By acknowledging Chaiken et al.’s (1989) theoretical extension of the heuristic-systematic model (Chaiken, 1980) we provide empirical evidence that source credibility intensifies the impact of positive OCRs due to the additivity effect. In contrast, credible negative information is not more influential than incredible information. A similar mechanism becomes operational when considering product type. Here, positive OCRs about experience goods have a stronger influence on product evaluations than similarly valenced information about search goods. This research provides further support for the crucial role of credible, positive OCRs in affecting consumer behavior in contrast to their negative counterparts. From a practical perspective, marketers should consider including highly credible OCRs from trustworthy and experienced customers’ peers as decision aids. This can be achieved, for instance, by including personal postings from Facebook. Such a strategy is particularly efficient as positive OCRs increase the consumer’s confidence towards the product while credible negative OCRs are not more harmful than incredible ones.
