ABSTRACT

The prefabricated construction industry, also known as off-site construction, has been operating in North America for several years now and differs from traditional construction in its much shorter project timelines, lower costs, and increased build quality. However, the lack of a suitable and efficient assembly solution has been identified by many as a barrier to the use of off-site construction for larger buildings. To maximise the benefits of off-site manufacturing for multistorey buildings, an automated connection solution is presented in this paper. A new plug-in self-locking device was developed according to the following product design phases: on-site observations, definition of the problem and product specifications, solution generation, prototyping, fabrication, and testing. The plug-in self-locking device allows the assembly process to be accelerated by eliminating the fastening steps and a higher completion of modules off-site to be achieved. The design bears the compressive, tensile, and shear loads and contributes to the load path of the building.

ABSTRACT

Future trends in sustainable food consumption include the emergence of short food supply chains and growing interest in local food products. Among the drivers are the more urgent sustainability expectations, the emphasis on environmental and social responsibility, and the changing consumer needs, of which the desire for healthy and quality products, curiosity, uniqueness, and experience are the most prominent drivers. Today’s customers are becoming more aware and open to culinary discoveries and exotic delights. In this study, we investigated the importance of product attributes related to local products, and the motivational factors that determine purchase intentions. The significance of our work lies in the fact that we have studied young consumers’ intrinsic and extrinsic motivational factors. A quantitative consumer survey was conducted using a hybrid data collection method on a sample of 1756 respondents aged between 18 and 45 years. The questionnaire focused on product features, intrinsic and extrinsic motivational elements, and demographic characteristics. The results of our study provide strong evidence that the features associated with local products include but are not limited to the following: freshness, high quality, nutritional value, reliability, safety, evoking domestic flavours, naturalness, being healthy, environmentally friendly, etc. The motivational elements were grouped into four factors: hedonism, curiosity, nutritional value, and tradition. The main reasons for young respondents purchasing local food were taste and curiosity. Based on the results of the cluster analysis, we formed three groups having different features and different motivations for purchasing local products. Moreover, we had the opportunity to understand the attitudes and perceptions of young people towards buying local products. A key result of our study is that the “value-creators” segment considers local products to be healthy and nutritious.
