Technology Prizes for Climate Change Mitigation

We analyze whether technology inducement prizes could be a useful complement to standard research grants and contracts in developing climate change mitigation technologies. We find that there are important conceptual advantages to using inducement prizes in certain circumstances. These conceptual inferences are borne out by an examination of the track record of prizes inducing research into public goods, including relevant energy technologies. However, we also find that the prizes’ successes are contingent on their proper design. We analyze how several important design elements could influence the effectiveness of a climate technology prize.inducement prize, research and development, climate change, technology, policy

The Butz Stops Here: Why the Food Movement Needs to Rethink Agricultural History

From the 1890s to the 1930s, rural Americans played a vital role in radical leftist politics. While specialists know this history well, the public tends to know a folk history, written by figures associated with contemporary food movements. This folk history rests on several key myths, which cover different periods of modern history from the New Deal to the present. This essay challenges these myths to reveal the causes and extent of the suffering endured by rural families in the 20th century, which in turn, decimated the populist left. A reconsideration of the history of agricultural policy will help food-system reformers develop a more radical and effective vision for rural Americ

The Impact of Long-Term Generation Contracts on Valuation of Electricity Generating Assets under the Regional Greenhouse Gas Initiative

The Regional Greenhouse Gas Initiative is an effort by nine states to constrain carbon dioxide emissions from the electric power sector using a cap-and-trade program. This paper assesses the importance of long-term electricity contracts under the program. We find that 12.2% of generation will be accounted for by long-term contracts in 2010, affecting select nuclear, hydroelectric, and cogeneration units. The contracts will have a negligible effect on the wholesale marginal cost of electricity and a small effect on retail price. States may want to consider contracts on a case-by-case basis when making decisions about the initial distribution of emission allowances, but they should account for effects on the portfolio of plants owned at the firm level, not the effects on individual facilities. Because of their relatively small effect, it seems unnecessary to allow the existence of long-term contracts to dictate the design of the overall program.climate, state policy, Regional Greenhouse Gas Initiative, long-term contracts, electricity

Real-Time Monitoring of Paraquat Photodegradation Using Colloidal Gold Surface Enhanced Raman Spectroscopy

Monitoring chemical reactions in aqueous solution is a challenge because most instrumental techniques either are not suited for the rapid timescales, are not sensitive enough to detect products at low concentrations, or do not have sufficient structure-to-spectrum relationships. Raman spectroscopy is a promising method to monitor reactions, as it is fast, dependent on chemical structure, and has little interference from water. However, Raman scattering is generally very weak. Surface-enhanced Raman spectroscopy (SERS) improves the signal strength of Raman spectroscopy by using a metal surface plasmon, or oscillation of the surface’s electrons, to allow for highly selective and sensitive detection and characterization of analyte molecules. An aqueous colloid of partially aggregated gold nanoparticles is an accessible substrate for generating plasmons necessary for SERS. The analyte is adsorbed to the nanoparticles, initiating aggregation. A surfactant (sodium dodecyl sulfate) is added at an optimal time to arrest aggregation, leading to a highly stable substrate. Because of this, SERS enhancement is present over multiple hours under powerful UV light. As peaks in the Raman spectra evolve, structural changes can be detected. Paraquat, a common yet dangerous herbicide that is banned in the UK, China, Brazil, and many other countries, was monitored with SERS in real time as it degrades when exposed to intense light, analogous to sunlight. The photodegradation products have not been well characterized in the past, but methylpyridinium is expected. A reaction mechanism and kinetics can then be determined for this reaction. Gathering better data about paraquat and its degradation in the environment may help users apply or sequester paraquat to minimize harm to humans and the ecosystem

Interfacing peripheral nerve with macro-sieve electrodes following spinal cord injury

Macro-sieve electrodes were implanted in the sciatic nerve of five adult male Lewis rats following spinal cord injury to assess the ability of the macro-sieve electrode to interface regenerated peripheral nerve fibers post-spinal cord injury. Each spinal cord injury was performed via right lateral hemisection of the cord at the T9–10 site. Five months post-implantation, the ability of the macro-sieve electrode to interface the regenerated nerve was assessed by stimulating through the macro-sieve electrode and recording both electromyography signals and evoked muscle force from distal musculature. Electromyography measurements were recorded from the tibialis anterior and gastrocnemius muscles, while evoked muscle force measurements were recorded from the tibialis anterior, extensor digitorum longus, and gastrocnemius muscles. The macro-sieve electrode and regenerated sciatic nerve were then explanted for histological evaluation. Successful sciatic nerve regeneration across the macro-sieve electrode interface following spinal cord injury was seen in all five animals. Recorded electromyography signals and muscle force recordings obtained through macro-sieve electrode stimulation confirm the ability of the macro-sieve electrode to successfully recruit distal musculature in this injury model. Taken together, these results demonstrate the macro-sieve electrode as a viable interface for peripheral nerve stimulation in the context of spinal cord injury

Conditionally Sexual: Constructing the sexual health needs of men and teenage boys with a moderate to profound intellectual disability

ABSTRACT This thesis reports on a study which explored the sexual health needs of men and teenage boys with a moderate to profound intellectual disability. Qualitative in design, this study was exploratory in nature as it sought to develop theoretical knowledge in male sexual health as a broad concept as opposed to testing a theory or hypothesis related to sexual health. Literature on sexuality and intellectual disability was reviewed in addition to male-specific literature on intellectual disability. In addition, mainstream literature on sexuality, sexual health, masculinity and men’s health was also reviewed. The literature review highlighted that the intellectual disability specific literature had largely ignored mainstream literature and had failed to acknowledge emerging work in men’s health and masculinities. Moreover, the literature identified a problematised focus toward sexual matters and males with an intellectual disability. The topic of enquiry was explored via an ethnomethodological design. Data consisted of interviews with 17 paid support staff, over 100 hours participant observation in community group homes, and triangulated with relevant artefacts from the field. The constant comparative method was used to analyse the data. Participants described the notion of men and teenage boys with a moderate to profound intellectual disability as being Conditionally Sexual. Conditionally Sexual was framed by three interconnected themes: 1) sexual development, 2) conditionally masculine, and 3) gendered service delivery. Through consideration of the implications to theory, practice, research, and policy, a propositional framework for a masculine health environment has been outlined. This framework is based on a salutogenic notion of male sexual health and the development of a healthy masculinity
