Reasons that post-secondary culinary students enrolled in for-profit educational institutions drop out and methods that can be used to increase retention rates

Most people appreciate and understand the value of education. They are aware that education can significantly increase the potential earnings a person can make over their lifetime, improve the security and stability in their chosen profession, improve their competency, and make it easier to be successful at their job. Education can also increase the amount of respect a person may receive from their peers and all of these things can improve the overall quality of their life. Education can be extremely important to an individual’s success

Lessons from nature about solar light harvesting

Solar fuel production often starts with the energy from light being absorbed by an assembly of molecules; this electronic excitation is subsequently transferred to a suitable acceptor. For example, in photosynthesis, antenna complexes capture sunlight and direct the energy to reaction centres that then carry out the associated chemistry. In this Review, we describe the principles learned from studies of various natural antenna complexes and suggest how to elucidate strategies for designing light-harvesting systems. We envisage that such systems will be used for solar fuel production, to direct and regulate excitation energy flow using molecular organizations that facilitate feedback and control, or to transfer excitons over long distances. Also described are the notable properties of light-harvesting chromophores, spatial-energetic landscapes, the roles of excitonic states and quantum coherence, as well as how antennas are regulated and photoprotected. © 2011 Macmillan Publishers Ltd
