Abstract

Proposed in this paper is a dynamic resource-aware routing and frequency slots allocation scheme with consideration of both BER requirement and distance adaptive modulation (RA-BERR-DA) for spectrum-sliced elastic optical path networks (SLICE).Numerical simulations are conducted to analysis network performance such as blocking rate and the number of used frequency slots. The results demonstrate that this scheme is able to decrease traffic blocking and improve resource utilization in dynamic spectrum assignment. DOI: http://dx.doi.org/10.11591/telkomnika.v10i7.1448

Abstract

Even though Asian countries are expected to become a dominant market for organic foods in the coming years, there are few studies which focused on young Asian consumers’ organic food purchase behaviour. This study aims to investigate how attitude, subjective norm, perceived behavioural control, and health concerns influence consumers’ intention to purchase and consume organic foods. A purposive sampling method was adopted for this study and a total of 289 usable questionnaires were collected for empirical testing of the postulated hypotheses using SPSS and structural equation modelling (SEM). The results showed that attitude, subjective norm, perceived behavioural control and health concern positively influenced intention. In addition, subjective norm positively influenced attitude while attitude played a partial mediation effect on the relationship between subjective norm and intention. Lastly, the theoretical and practical implications as well as the limitations of the study are discussed.
