SURE Impact? An Empirical Investigation of Moral Hazard and Adverse Selection Behavior

The Supplemental Revenue Assistance Payments (SURE) program, enacted under the 2008 Farm Bill, is intended to provide indemnity payments to producers whose crop losses exceed 50% of their historical average yields. However, indemnification does not require that the farm is located in a region designated a disaster relief area -- a provision that can create significant moral hazard incentives. This study is the first to perform an empirical analysis of possible moral hazard behavior in corn, soybean, and wheat markets in response to the SURE program. Results suggest that an increase in crop insurance demand after the enactment of SURE may be due to the program's moral hazard incentives.Agricultural and Food Policy, Farm Management,

A review of commercialisation mechanisms for carbon dioxide removal

The deployment of carbon dioxide removal (CDR) needs to be scaled up to achieve net zero emission pledges. In this paper we survey the policy mechanisms currently in place globally to incentivise CDR, together with an estimate of what different mechanisms are paying per tonne of CDR, and how those costs are currently distributed. Incentive structures are grouped into three structures, market-based, public procurement, and fiscal mechanisms. We find the majority of mechanisms currently in operation are underresourced and pay too little to enable a portfolio of CDR that could support achievement of net zero. The majority of mechanisms are concentrated in market-based and fiscal structures, specifically carbon markets and subsidies. While not primarily motivated by CDR, mechanisms tend to support established afforestation and soil carbon sequestration methods. Mechanisms for geological CDR remain largely underdeveloped relative to the requirements of modelled net zero scenarios. Commercialisation pathways for CDR require suitable policies and markets throughout the projects development cycle. Discussion and investment in CDR has tended to focus on technology development. Our findings suggest that an equal or greater emphasis on policy innovation may be required if future requirements for CDR are to be met. This study can further support research and policy on the identification of incentive gaps and realistic potential for CDR globally

Strategies for the Concise Synthesis of the Akuammiline Alkaloids

The akuammiline alkaloids are an intriguing class of natural products that display an array of biological activities and structural diversity. Despite being known for over 125 years, it is surprising that these complex monoterpene indole alkaloids have only recently elicited sustained interest from the synthetic community, especially given the storied history of this broad family in the development of the art of total synthesis, and, in particular, heterocyclic chemistry. This dissertation details our efforts to address these deficiencies through work directed at the unique akuammiline alkaloid (+)-scholarisine A, ultimately yielding a concise and enantiospecific preparation of this challenging target. Building on this initial success, we have initiated studies aiming to generalize these strategies to the akuammiline class as whole, efforts that have been empowered by the development of several novel synthetic transforms. These investigations have culminated in the efficient synthesis of a collection of advanced intermediates en route to the varied frameworks represented by strictamine and 10-demethoxynorvincorine. In addition, we have leveraged our expertise gained within these challenging contexts towards a method with utility beyond the akuammiline class, one that is likely to find broad application in both natural product synthesis and the assembly of medicinally-relevant building blocks

A novel ECG-biomarker for cardiac arrest during hypothermia

Background: Treatment of arrhythmias evoked by accidental or therapeutic hypothermia and rewarming remains challenging. We aim to find an ECG-biomarker that can predict ventricular arrhythmias at temperatures occurring in therapeutic and accidental hypothermia. Main body: Evaluation of ECG-data from accidental and therapeutic hypothermia patients and experimental data on ECG and ventricular fibrillation (VF) threshold in hypothermic New Zealand White Rabbits. VF threshold was measured in rabbit hearts cooled to moderate (31 °C) and severe (17 °C) hypothermia. QRS-interval divided by corrected QT-interval (QTc) was calculated at same temperatures. Clinical QRS/QTc data were obtained after a systematic literature review. Rabbit QRS/QTc values correlated with risk for VF (correlation coefficient: 0.97). Human QRS/QTc values from hypothermic patients, showed similar correlation with risk for ventricular fibrillation in the experimental data (correlation coefficient: 1.00). Conclusions: These calculations indicate that QRS/QTc has potential as novel biomarker for predicting risk of hypothermia-induced cardiac arrest. Our findings apply both to victims of accidental hypothermia and to patients undergoing therapeutic hypothermia during surgery or after e.g. cardiac arrest

Addressing regulatory challenges for offshore geological carbon storage in the UK: a policy brief

This brief focuses on the U.K. policy and regulatory framework and reforms available to the UK as it looks to scale-up the CCS industry effectively and begin safe geological CO2 storage (GCS) on the UK offshore continental shelf (UKCS). The brief covers the current state of offshore CCS regulation and discusses opportunities available to streamline legislation, regulation and policy surrounding access to CO2 storage on the UKCS, based on insights from diverse stakeholders regarding this regulation. We discuss the consequences of these findings for policy, industrial scale-up of geological storage, and the future direction of UK CCS policy and legislation. The UK has a developed regulatory environment for offshore GCS, but regulatory challenges remain. This is the central gap that this brief aims to address

Dealing with the devil: weight loss concerns in young adult women with type 1 diabetes.

AIMS AND OBJECTIVES: To examine the weight loss concerns of young adults with type 1 diabetes. BACKGROUND: Eating disorders are prevalent in young women with type 1 diabetes. DESIGN: Qualitative. METHODS: Interviews with 35 young adults (23-30 years of age) with type 1 diabetes and 13 healthcare professionals. RESULTS: Most female interviewees were concerned about the difficulties of losing weight when having diabetes. Six female interviewees developed severe eating disturbances when they were younger. These women initially regarded their disturbed eating behaviour positively and engaged in weight loss activities intermittently. However, over time, they lost control of their behaviour, and it came to dominate their lives. Family conflict often intensified disordered eating behaviours. Eventually all of these women managed to transition away from their behaviour, although this process took, for some of them, several years. Several of them (now in their early to late twenties), however, continued to struggle with weight loss impulses. Healthcare professionals felt that eating- and weight-related issues often went undiagnosed and undocumented in young adult women with type 1 diabetes. CONCLUSION: Many young women with type 1 diabetes are worried about their weight, but will not engage in risky weight loss activities because of concerns about their health. A minority of young adult women will develop more severe eating-related disturbances. These eating disturbances may last a significant amount of time before clinicians become aware of them. These women may also experience disordered weight loss impulses for sometime after clinical interventions. RELEVANCE TO CLINICAL PRACTICE: Clinicians should screen young adult women with type 1 diabetes for eating disorders and monitor young adult women who have developed eating disorders over the longer term. There may be a need to provide asymptomatic young women with diabetes with information about the potential risks of insulin omission
