Consumer laundry practices in Germany

Sustainability is a guiding principle for a responsible, future‐oriented 21st century lifestyle and this already begins in private households with the daily household tasks. Approximately 25% of an average household's electricity consumption is required to do the laundry and dishwashing – 5% alone is for washing clothes with a corresponding energy consumption of 6 billion kilowatt hours. In addition, 600 000 tonnes of detergent and 330 million cubic metres of water are used for textile care in Germany. These figures provide the rationale for the scientific study of current practices of using washing machines and for a resulting estimate of the latent energy‐saving potential in German households. In the context of the in‐home study presented here, 236 private households throughout Germany were studied with respect to their washing practices and existing knowledge about topics on the sustainable, energy‐saving use of their washing machines. Overall, across all households 2867 wash cycles were individually recorded and subsequently analysed over a 4‐week period. The results of this study show that washing machines tend to be underloaded, and therefore maximum loading of the machines could lead to a reduction of wash cycles per household. With respect to detergent dosage, it was determined that the consumer does not adjust the dosage to the textile type, load size, soil level and/or water hardness, and this can lead to under‐ or overdosing depending on prevailing conditions. Finally, the selection of the wash temperature showed a 90°C/95°C programme was only chosen in 2.3% of all recorded wash cycles, however, every fourth cycle was completed at 60°C. Therefore, adjusting the load size and detergent dosage as well as selecting the right wash temperature are key themes to be taken into account in future consumer communication about energy‐saving households.     

The demand for alcohol in the United Kingdom

Using the AIDS model, we show that there exists for the UK a stable long-run relationship between expenditure shares on beer, cider, spirits and wine, alcohol prices, total alcohol expenditure and a range of non-economic variables relating to advertising, licensing, the employment, social class and demographic characteristics of consumers, and climate. Our estimates of key price and income elasticities generally lie between those found from other time-series studies (which exclude most of these non-economic variables) and those found from cross-section studies (which generally include them). However, the restrictions required for separability, homegeneity and symmetry (although not those for perfect price aggregation) are decisively rejected.     

Integrating inside and outside innovators: a sociotechnical systems perspective

Innovation literature stresses the importance of opening the innovation process to internal and external innovators. The question of what determines the integration of these types of innovators in the innovation process remains open. We use a sociotechnical systems perspective to address a number of challenges with respect to this matter: an organization deploying different innovation practices to open the innovation process might not be aware which types of innovators are de facto integrated in its innovation process. Alternatively, an organization targeting the integration of a particular type of innovator might not use the suitable innovation practices to integrate the knowledge of this type of innovator. To address these challenges, our comparative case-study analysis in 15 medium-sized firms derives a theoretical framework proposing that a combined analysis of innovation practices and underlying social interactions is needed to decide about the integration of a particular type of innovator in the innovation process. Being aware of these interrelations will allow organizations to act more consciously when opening their innovation processes.     

The perceived usefulness of knowledge supplied by foreign client networks

The network surrounding a firm's foreign clients has large influence on its ability to act in the market. How firms can utilize the knowledge supplied by client networks is therefore of great importance to their business with clients. Many studies show the usefulness of foreign clients and suppliers, whereas less attention has been given to the usefulness of knowledge supplied by clients’ network, such as clients’ clients, clients’ supplementary suppliers and competitors to the firm. This study contributes to international business research on networks by investigating the knowledge supplied by client networks for a firm doing business with a specific foreign client on a sample of 494 firms. A LISREL analysis demonstrates that knowledge supplied by client networks is more useful the more experienced the firm. Client networks are also more useful the more knowledge the firm has of its client, the more the firm needs knowledge of its clients and suppliers, the higher the cost of the client relationship, and the more standardized the product. A major conclusion is that the client network knowledge is more useful the further a firm's collaboration with the client, presumably as a result of the new, and more embedded business that the firm develops with the client. Implications are that client networks are resources that can be important competitive advantages for the internationalizing firm.     

Microeconometric models of tourists'' destination choice

The focus of this paper is on the microeconometric analysis of spatial choice in a cross section. Nested multinomial logit models are used to analyze the determinants of individual choice among destinations and vacation activities. Cramer and Ridder's likelihood ratio test for pooled alternatives in multinomial logit models is sequentially applied in order to determine the adequate aggregation level of the mutually exclusive alternatives in the choice set. The specification test suggested by Chesher and Santos Silva (1992) is used to investigate whether or not the IIA proposition is fulfilled within the assumed choice subsets.     

How songs from growing up and viewers' attachment styles affect video ads' effectiveness

We propose that the positive effect of coming-of-age songs on ad effectiveness arises from a mediation process where the music-evoked interpersonal memories of growing up stored in the brain and their accompanying emotions inevitably play a role, but not so straightforwardly as previously suggested. Rather, their effects work through the heightened familiarity of and peaked preferences for coming-of-age songs. We also propose that these sequentially mediated effects are moderated by viewers' developmental attachment styles. We test and find support for these propositions in three multimethod studies with more than 1200 participants born between the 40s and the mid-70s and almost 60 popular songs released between the 60s and the 2010s. We discuss the implications of our findings, namely for age-segmented video ads, and suggest future research directions.
