A Laboratory Assessment of Tradable Fishing Allowances

Transferable allowance management systems are receiving increased attention from fishery managers and stakeholders alike. We use a laboratory experiment in which human subjects play the role of fishers to evaluate the promised economic efficiency of tradable allowance systems. In an experiment designed to parallel the most common rules for trading allowances, we find that allowance prices are only weakly associated with the value of the fishing right it provides. Instead, we find a high degree of price variability, consistent with field experiences. In the lab, this variability hampers convergence and supports speculation, leading to average prices much higher than the equilibrium value of allowances. During this protracted price discovery, allowances are misallocated and efficiency falls. Modifications to the market institutions used in most tradable allowance systems to improve price discovery and enhance efficiency are discussed.fishery management, ITQs, tradable fishing rights, transferable allowances, experiments, asset markets, Resource /Energy Economics and Policy, Q22, Q28, G12,

Impact of Vegetative Treatment Systems on Multiple Measures of Antibiotic Resistance in Agricultural Wastewater

Wastewater is an important vector of antibiotic resistant bacteria and antibiotic resistance genes (ARB/G). While there is broad agreement that ARB/G from agricultural (ag) wastewaters can be transported through the environment and may contribute to untreatable infectious disease in humans and animals, there remain large knowledge gaps surrounding applied details on the types and amounts of ARB/G associated with different agricultural wastewater treatment options and different ag production systems. This study evaluates a vegetative treatment system (VTS) built to treat the wastewater from a beef cattle feedlot. Samples were collected for three years, and plated on multiple media types to enumerate tetracycline and cefotaxime-resistant bacteria. Enterobacteriaceae isolates (n = 822) were characterized for carriage of tetracycline resistance genes, and E. coli isolates (n = 673) were phenotyped to determine multi-drug resistance (MDR) profiles. Tetracycline resistance in feedlot runoff wastewater was 2-to-3 orders of magnitude higher compared to rainfall runoff from the VTS fields, indicating efficacy of the VTA for reducing ARB over time following wastewater application. Clear differences in MDR profiles were observed based on the specific media on which a sample was plated. This result highlights the importance of method, especially in the context of isolate-based surveillance and monitoring of ARB in agricultural wastewaters

The Effects of Marriage Equality in Massachusetts: A survey of the experiences and impact of marriage on same-sex couples

May 17th, 2009 marks the 5th year of marriage equality in the state of Massachusetts. To mark this anniversary, the Massachusetts Department of Public Health conducted the largest survey to date of married same-sex couples, the Health and Marriage Equality in Massachusetts (HMEM) survey. During the past year, four other states have extended marriage to same-sex couples and several other states are considering marriage legislation. The HMEM data allows us to address important questions that arise as other states consider whether to extend marriage to same-sex couples. The data provides answers to several key questions: Who is getting married? Why are same-sex couples getting married? What impact has marriage had on same-sex relationships? And, what impact has marriage had on the children of same-sex couples

The Fiscal Impact of Extending Federal Benefits to Same-Sex Domestic Partners

This report finds that offering health and other benefits to the same-sex partners of federal employees would add $41 million to the federal budget in the first year of coverage. Over ten years the report predicts the budgetary cost will be$675 million, a small percentage of the federal budget. The report also takes into account the added federal income taxes that will be paid by federal employees if they sign a partner up for health insurance. It estimates the cost of including partners in retirement benefits, work injury and death compensation, and travel and relocation expenses. Many benefits offered to federal employees, such as life insurance and family and medical leave, can be offered to domestic partners at no additional cost to the federal government

Analog of the Clauser-Horne-Shimony-Holt inequality for steering

The Clauser-Horne-Shimony-Holt (CHSH) inequality (and its permutations), are necessary and sufficient criteria for Bell nonlocality in the simplest Bell-nonlocality scenario: 2 parties, 2 measurements per party and 2 outcomes per measurement. Here we derive an inequality for EPR-steering that is an analogue of the CHSH, in that it is necessary and sufficient in this same scenario. However, since in the case of steering the device at Bob's site must be specified (as opposed to the Bell case in which it is a black box), the scenario we consider is that where Alice performs two (black-box) dichotomic measurements, and Bob performs two mutually unbiased qubit measurements. We show that this inequality is strictly weaker than the CHSH, as expected, and use it to decide whether a recent experiment [Phys. Rev. Lett. 110, 130401 (2013).] involving a single-photon split between two parties has demonstrated EPR-steering.Comment: Expanded v2, new results, new figure. 9 pages, 2 figure

Evidence against the Detectability of a Hippocampal Place Code Using Functional Magnetic Resonance Imaging

Individual hippocampal neurons selectively increase their firing rates in specific spatial locations. As a population, these neurons provide a decodable representation of space that is robust against changes to sensory- and path-related cues. This neural code is sparse and distributed, theoretically rendering it undetectable with population recording methods such as functional magnetic resonance imaging (fMRI). Existing studies nonetheless report decoding spatial codes in the human hippocampus using such techniques. Here we present results from a virtual navigation experiment in humans in which we eliminated visual- and path-related confounds and statistical limitations present in existing studies, ensuring that any positive decoding results would represent a voxel-place code. Consistent with theoretical arguments derived from electrophysiological data and contrary to existing fMRI studies, our results show that although participants were fully oriented during the navigation task, there was no statistical evidence for a place code
