??Puede una persona sedentaria mantenerse sana a trav??s de la alimentaci??n?

A lo largo de este trabajo responder?? a la pregunta en la que me cuestiono si una persona sedentaria puede ser una persona sana ??nicamente mediante la alimentaci??n. Para ello hablar?? del sedentarismo, qu?? es lo que consideramos persona sana y algunas de las razones por las que una persona llega a ser sedentaria y no realiza actividad f??sica. A su vez, veremos en qu?? consiste una correcta alimentaci??n, los errores nutricionales m??s comunes, y a su vez investigaremos la alimentaci??n en personas sedentarias.

Valuation of Wind Energy Projects: A Real Options Approach

We address the valuation of an operating wind farm and the finite-lived option to invest in it under different reward/support schemes: a constant feed-in tariff, a premium on top of the electricity market price (either a fixed premium or a variable subsidy such as a renewable obligation certificate or ROC), and a transitory subsidy, among others. Futures contracts on electricity with ever longer maturities enable market-based valuations to be undertaken. The model considers up to three sources of uncertainty: the electricity price, the level of wind generation, and the certificate (ROC) price where appropriate. When analytical solutions are lacking, we resort to a trinomial lattice combined with Monte Carlo simulation; we also use a two-dimensional binomial lattice when uncertainty in the ROC price is considered. Our data set refers to the UK. The numerical results show the impact of several factors involved in the decision to invest: the subsidy per MWh generated, the initial lump-sum subsidy, the maturity of the investment option, and electricity price volatility. Different combinations of variables can help bring forward investments in wind generation. One-off policies, e.g., a transitory initial subsidy, seem to have a stronger effect than a fixed premium per MWh produced.
