Delegation Success and Policy Failure: Collective Delegation and the Search for Iraqi Weapons of Mass Destruction

Tierney argues that international delegation can have important consequences, even for powerful states. In particular, he contends that the US delegation of inspection authority to United Nations weapons inspectors and to the International Atomic Energy Association after the Gulf War of 1990-91 entailed significant sovereignty costs by affecting the timing and costliness of the subsequent 2003 US invasion of Iraq. Among other things, he notes that the inspectors\u27 independent behavior made it much more difficult for the US to assemble the type of multilateral coalition that would share the costs as it had in the earlier Gulf War. Tierney also notes that this example shows how different states can pay different costs as the result of the same episode of international delegation

Explaining the Allocation of Bilateral and Multilateral Environmental Aid to Developing Countries

In this paper we examine how international development assistance for environmental purposes is allocated to developing countries. In particular, we investigate whether there are patterned differences between environmental aid for international public goods projects versus environmental projects having more localized impacts. We empirically investigate these questions using project project level development assistance data.International Development,

Creating New Knowledge with Undergraduate Students: Institutional Incentives and Faculty Agency

Undergraduate students today face a more demanding and competitive labor market than their parents’ generation. In response, some pursue double majors to signal breadth to potential employers and to improve their job prospects. Some students also realize that a strong signal of workplace readiness is acquiring in-demand skills through independent and collaborative research. In this article, four professors at an undergraduate-focused public university in the United States share their experiences working with undergraduate students on research, focusing on the “supply side” of student research training and mentoring. We discuss how institutions can support differently situated faculty members, who face different career incentives and constraints, to integrate undergraduates in their research. We also address the limits of what is possible for faculty‐student research and suggest ways to overcome them

Tracking Under-Reported Financial Flows: China’s Development Finance and the Aid-Conflict Nexus Revisited

China’s development finance is sizable but reliable information is scarce. To address critical information gaps, we introduce a new open source methodology for collecting project-level development finance information and create a database of Chinese official finance to Africa from 2000-2011. Our initial data collection efforts found that China’s official finance commitments amount to approximately US$ 73 billion over the 2000-2011 period. We provide details on 1,511 non-investment projects to 50 African countries. We use this database to extend previous research on the aid-conflict nexus. Our results show that sudden withdrawals of “traditional” aid are only more likely to induce conflict in the absence of sufficient alternative funding from China. More broadly, these findings highlight the importance of gathering better data on the development activities of China and other non-traditional donors to better understand the link between foreign aid and conflict

Differential Binding of Co(II) and Zn(II) to Metallo-β-Lactamase Bla2 from \u3cem\u3eBacillus anthracis\u3c/em\u3e

In an effort to probe the structure, mechanism, and biochemical properties of metallo-β-lactamase Bla2 from Bacillus anthracis, the enzyme was overexpressed, purified, and characterized. Metal analyses demonstrated that recombinant Bla2 tightly binds 1 equiv of Zn(II). Steady-state kinetic studies showed that mono-Zn(II) Bla2 (1Zn-Bla2) is active, while di-Zn(II) Bla2 (ZnZn-Bla2) was unstable. Catalytically, 1Zn-Bla2 behaves like the related enzymes CcrA and L1. In contrast, di-Co(II) Bla2 (CoCo-Bla2) is substantially more active than the mono-Co(II) analogue. Rapid kinetics and UV−vis, 1H NMR, EPR, and EXAFS spectroscopic studies show that Co(II) binding to Bla2 is distributed, while EXAFS shows that Zn(II) binding is sequential. To our knowledge, this is the first documented example of a Zn enzyme that binds Co(II) and Zn(II) via distinct mechanisms, underscoring the need to demonstrate transferability when extrapolating results on Co(II)-substituted proteins to the native Zn(II)-containing forms
