Purpose -This paper seeks to understand the triggers which influence the adoption (and the discontinuation) of online grocery shopping. Specifically, the research aims to establish the role of situational factors in the process of adoption. Design/methodology/approach -A two-step research process is employed. First, exploratory qualitative research is carried out, with the purpose of gaining an in-depth understanding of consumers' online grocery shopping behaviour. This is followed by a large-scale quantitative survey extending the findings of the qualitative research and validating the role of situational factors in instigating the commencement (and discontinuation) of online grocery buying. Cluster analysis is used to segment consumers based on the importance of specific types of situations. Findings -Both qualitative and quantitative results establish the importance of situational factors, such as having a baby or developing health problems, as triggers for starting to buy groceries online. Many shoppers are found to discontinue online grocery shopping once the initial trigger has disappeared or they have experienced a problem with the service. Practical implications -While situational factors are beyond a marketer's control, they could be used as a basis for marketing communications content and target advertising, for instance, by using magazines directed at new parents. Originality/value -The importance of situational factors as triggers for the adoption of online grocery shopping suggests an erratic adoption process, driven by circumstances rather than by a cognitive elaboration and decision. The adoption of online shopping seems to be contingent and may be discontinued when the initiating circumstances change.

Recent gains in the performance of 3D graphics hardware and rendering systems have not been matched by a corresponding improvement in our knowledge of how to interact with the virtual environments we create; therefore there is a need to examine these further if we are to improve the overall quality of our interactive 3D systems. This paper examines some of the interaction techniques which have been developed for object manipulation, navigation and application control in 3D virtual environments. The use of both mouse-based techniques and 3D input devices is considered, along with the role of feedback and some aspects of tools and widgets.

Small and medium sized enterprises (SMEs) located in the least developed countries (LDCs), operate in distinctively hostile institutional environments compared to those in developed economies. Better understanding of the determinants of SME innovation in such environments is important for the development of private sector in LDCs, because innovative SMEs are crucial for sustainable economic growth. Yet, determinants of SME innovation in LDCs have hardly been studied. Considering the potential relevance of internationalization for SME innovation in LDCs, as means of overcoming domestic environmental constraints, this paper investigates the influence of foreign technology licensing, exports and imports on SME innovation in LDCs. The study employs data from 1,058 manufacturing SMEs from Sub-Saharan LDCs-Djibouti, Tanzania, Uganda, Zambia and the Democratic Republic of Congo. The findings suggest that foreign technology licensing is found to be positively and statistically associated with SME product and process innovations in Sub-Saharan LDCs. Findings are compared with those from developed economies in order to identify distinctive features. The implication is that SMEs in Sub-Saharan LDCs need to be supported by different policies compared to developed economies. The results also show that R&D, firm size, sectoral characteristics and access to finance are important determinants of SME innovation.

Purpose: Grounded on approach/avoidance behaviour theory, this study develops a typology of grocery shoppers based on the concomitant perceived advantages and disadvantages of shopping online and in store for a single cohort of consumers who buy groceries in both channels. Methodology:A survey design was employed using a sample of 871UK shoppers who had purchased groceries online and offline. The survey instrument contained items that measured the perceived advantages and disadvantages of grocery shopping online, and items relating to the perceived advantages and disadvantages of grocery shopping in traditional supermarkets. Items were selected from the extant literature and subjected to content and face validity checks. Cluster analysis was used to develop typologies of online and offline grocery shoppers. The inter-relation between the two typology sets was then examined. Findings:The results of the research provide several insights into the characteristics, perceptions and channel patronage preferences of grocery shoppers. In particular, profiling e-grocery shoppers on the basis of their concomitant perceptions of shopping online and in store suggests that the choice of whether to shop online or in store may be driven not by the perceived advantages of one channel versus the other, but by the desire to avoid the greater disadvantages of the alternative. These perceptions differ somewhat between different consumer groups.Originality/value: This study makes a noteworthy contribution to the Internet and general shopping literature by providing a profile of grocery shoppers based on their concomitant and often conflicting perceived advantages and disadvantages of shopping online and their perceived advantages and disadvantages of shopping in traditional supermarkets. The use of a single cohort of consumers overcomes the bias in previous studies that employ separate cohorts of online and offline shoppers and reveal important insights into the complex perceptions and behaviours of multi-channel grocery shoppers.
