Description
There has been considerable advancement in the algae research field to move algae production for biofuels and bio-products forward to become commercially viable. However, there is one key element that humans cannot control, the natural externalities that impact production. An algae cultivation system is similar to agricultural crop farming practices. Algae are grown on an area of land for a certain time period with the aim of harvesting the biomass produced. One of the advantages of using algae biomass is that it can be used as a source of energy in the form of biofuels. Major advances in algae research and development practices have led to new knowledge about the remarkable potential of algae to serve as a sustainable source of biofuel. The challenge is to make the price of biofuels from algae cost-competitive with the price of petroleum-based fuels. The scope of this research was to design a concept for an automated system to control specific externalities and determine if integrating the system in an algae cultivation system could improve the algae biomass production process. This research required the installation and evaluation of an algae cultivation process, components selection and computer software programming for an automated system. The results from the automated system based on continuous real time monitored variables validated that the developed system contributes insights otherwise not detected from a manual measurement approach. The implications of this research may lead to technology that can be used as a base model to further improve algae cultivation systems.

Description
Sustainability is intrinsically interdisciplinary, but the implementation of nontraditional pedagogy in this area is in its infancy. I aim to show that music can be a model to demonstrate the protean systems that consistently involve each of us. The connection between systems thinking and musical improvisation is evident in musical improvisation ensembles; it is a system unto itself with individual players connected through their musical composition. Musical improvisation allows the players to learn about systems and system behaviors. Such ability to identify and understand the underlying dynamics involved in complex social-ecological systems is fundamental to taking advantage of leverage points and working towards a sustainable future. I use music and musical improvisation to demonstrate the three concept groups of the systems thinking competency: 1) Variables, structures and functions 2) Resilience, self-organization and hierarchy and 3) Scales and domains. These parts constitute complex systems and are made easier with the analogy of music that provides a more representative language for discussing them in an intuitive way. Furthermore, improvisation activities provide a method and space for these future practitioners to rehearse working with systems. From accepting the nature of systems, one is accepting of their role in the system, which enables them to make changes. Musical improvisation is a valuable method to systems thinking because it requires future practitioners to engage in mindfulness, because it demands remaining in an intuitive stance so to be able to respond (not react) thoughtfully. My thesis will explore how the practice of musical improvisation can enhance the understanding of the three systems thinking content groups and to argue that such practice is unique and necessary as it provides opportunities to rehearse being effective change agents.
