- Customer participation behavior and customer citizenship behavior in hotels: testing co-production and value-in-use as mediatorsPublication . Sadighha, Jinous; Pinto, Patrícia; Martins Guerreiro, Maria Manuela; Campos, Ana CláudiaThis study investigates customers' contribution to value co-creation by exploring the associations between customer co-creation behavior, including customer participation and customer citizenship behavior, and co-creation processes, namely, co-production and value-in-use. It combines co-creation theory with equity and social exchange theories to propose a model for customer behavior towards value co-creation. Using Partial Least Squares Structural Equation Modeling (PLS-SEM), data were collected from tourists staying at hotels in Portugal. Results indicate that customer participation behavior envisages co-production and value-in-use, while the two forms of value co-creation subsequently improve customer citizenship behavior. Moreover, co-production enhances value-in-us. Additionally, customer participation behavior is associated with customer citizenship behavior through co-production and value-in-use. This research contributes to the co-creation theory by proving co-production and value-in-use as transforming mechanisms that turn customer participation behavior into customer citizenship behavior. Applying the proposed model as a managerial tool in hotels improves co-creation processes and boosts customer citizenship behavior.
- Exploring early acheulian technological decision-making: a controlled experimental approach to raw material selection for percussive artifacts in Melka Wakena, EthiopiaPublication . Paixão, Eduardo; Gossa, Tegenu; Gneisinger, Walter; Marreiros, Joao; Tholen, Sören; Calandra, Ivan; Hovers, ErellaThe evolution of human behaviour is marked by key decision-making processes reflected in technological variability in the early archaeological record. As part of the technological system, differences in raw material quality directly affect the way that humans produce, design and use stone tools. The selection, procurement and use of various raw materials requires decision-making to evaluate multiple factors such as suitability to produce and design tools, but also the materials’ efficiency and durability in performing a given task. Therefore, characterizing the physical properties of various lithic raw materials is crucial for exploring changes in human interactions with their natural environment through time and space and for understanding their technological behaviour. In this paper, we present the first step in an ongoing program designed to understand the decision-making criteria involved in the use of raw materials by the early Acheulian tool-makers at the Melka Wakena (MW) site-complex, located on the Ethiopian highlands. We present the results of the first experimental step, in which we identified and measured the engineering properties of raw materials in the lithic assemblages. These data serve as an objective, quantifiable baseline for natural experiments as well as archaeological inquiries into the technological decision-making processes of early Pleistocene hominins in Africa.
