THE INTERNAL AND EXTERNAL VALIDITY OF THE REGRESSION DISCONTINUITY DESIGN: A META‐ANALYSIS OF 15 WITHIN‐STUDY COMPARISONS

Theory predicts that regression discontinuity (RD) provides valid causal inference at the cutoff score that determines treatment assignment. One purpose of this paper is to test RD's internal validity across 15 studies. Each of them assesses the correspondence between causal estimates from an RD study and a randomized control trial (RCT) when the estimates are made at the same cutoff point where they should not differ asymptotically. However, statistical error, imperfect design implementation, and a plethora of different possible analysis options, mean that they might nonetheless differ. We test whether they do, assuming that the bias potential is greater with RDs than RCTs. A second purpose of this paper is to investigate the external validity of RD by exploring how the size of the bias estimates varies across the 15 studies, for they differ in their settings, interventions, analyses, and implementation details. Both Bayesian and frequentist meta‐analysis methods show that the RD bias is below 0.01 standard deviations on average, indicating RD's high internal validity. When the study‐specific estimates are shrunken to capitalize on the information the other studies provide, all the RD causal estimates fall within 0.07 standard deviations of their RCT counterparts, now indicating high external validity. With unshrunken estimates, the mean RD bias is still essentially zero, but the distribution of RD bias estimates is less tight, especially with smaller samples and when parametric RD analyses are used.     

UNICEF, syphilis and the state: negotiating female citizenship in the post-Second World War world

Few charitable organizations have achieved the status of global recognition enjoyed by UNICEF, the United Nations Children's Fund, which embodies the international effort to provide for needy children the world over. Created because of its synchronicity with the United Nations' stated purpose—to maintain peace in the world—UNICEF launched its operations in 1946. Its founding, early operations and eventual restructuring reveal a great deal about concurrent political and economic events, but also provide keen insight into international ideas about who qualified for full citizenship in the post-war world. The consequences of UNICEF's policies, procedures and practices posed challenges to notions of citizenship for both women and children. It challenged citizenship not by questioning sex-specific gender roles, but by judiciously adhering to the United Nations' promise to create equality for men and women alike. UNICEF found itself in the unique position to be able to globalize definitions of what constituted full citizenship in any nation, due to its rapid expansion throughout the world. Through its programs, especially those related to health care, it not only challenged these roles in the West, but began over several decades to complicate the definition of citizenship as it became a forceful presence in Asia and Africa throughout the 1970s.     

Energy policy under austerity localism: what role for local authorities?

In the UK, local authorities (LAs) have been placed at the forefront of domestic energy-reduction strategies as the responsible actors for coordinating policy in this sector. Yet, there has been little research regarding the role of LAs in this policy agenda, and their abilities to bring together stakeholders in the successful design and implementation of strategies to reduce energy demands. The paper aims to fill this gap by highlighting the relevance and importance of the energy policy sphere to local government studies, building on the idea of resilient LAs within the context of tensions between the localism agenda and the actual implementation of energy efficiency polices. This is achieved through multiple rounds of semi-structured interviews with LA officers. Our findings reveal that LAs, operating under a localism agenda, lack the freedoms and resources from central government to meet the needs of multiple stakeholders, resorting to short-term policies.     

Electro-acupuncture to prevent prolonged postoperative ileus:A randomized clinical trial

AIM:To examine whether acupuncture can prevent prolonged postoperative ileus(PPOI)after intraperitoneal surgery for colon cancer. METHODS:Ninety patients were recruited from the Fudan University Cancer Hospital,Shanghai,China. After surgery,patients were randomized to receive acupuncture(once daily,starting on postoperative day 1, for up to six consecutive days)or usual care.PPOI was defined as an inability to pass flatus or have a bowel movement by 96 h after surgery.The main outcomes were time to first fl...     

Programme and Project Cycle Management (PPCM): Lessons from South and North

This paper documents the lessons drawn from several years of practical work with a range of Programme and Project Cycle Management (PPCM) processes and tools. The need for PPCM training, and not simply Logical Framework training, is emphasised, as is the importance of using an experiential training methodology. Institutional ownership of both PPCM tools and approaches are considered to be vital for success. Since so many donors now use PPCM tools, the need for development professionals to have PPCM skills and knowledge is paramount. The value of logframes as a tool to both increase programme/project ownership and communication is highlighted. The importance of thinking outside the boxes of the logframe at the project/programme review stage is also emphasised.
