"Imagine a can opener"--the magic of principal stratum analysis.

چکیده
Abstract We extend Pearl's criticisms of principal stratification analysis as a method for interpreting and adjusting for intermediate variables in a causal analysis. We argue that this can be meaningful only in those rare cases that involve strong functional dependence, and even then may not be appropriate.

$Z_k$-Magic Labeling of Some Families of Graphs
For any non-trivial abelian group A under addition a graph $G$ is said to be $A$-textit{magic} if there exists a labeling $f:E(G) rightarrow A-{0}$ such that, the vertex labeling $f^+$ defined as $f^+(v) = sum f(uv)$ taken over all edges $uv$ incident at $v$ is a constant. An $A$-textit{magic} graph $G$ is said to be $Z_k$-magic graph if the group $A$ is $Z_k$ the group of integers modulo $k...
متن کاملThe Magic Pudding; Comment on “Four Challenges That Global Health Networks Face”
This commentary reflects on the contribution of this editorial and its “Three Challenges That Global Health Networks Face” to the totality of the framework developed over the past decade by Shiffman and his collaborators. It reviews the earlier works to demonstrate that the whole is greater than the sum of the parts in providing a package of tools for analysis of network effectiveness. Additi...
متن کاملUncertainty Analysis in MRI-based Polymer Gel Dosimetry
Background: Polymer gel dosimeters combined with magnetic resonance imaging (MRI) can be used for dose verification of advanced radiation therapy techniques. However, the uncertainty of dose map measured by gel dosimeter should be known. The purpose of this study is to investigate the uncertainty related to calibration curve and MRI protocol for MAGIC (Methacrylic and Ascorbic acid in Gelatin I...
متن کاملاثرغلظتهای مختلف ژلاتین در دز 36 گری پرتوهای گاما بر پارامترهای فراصوتی ژل پلیمر MAGIC-f
The aim of this study is to evaluate the effect of edible gelatin concentration as a polymerization agent on MAGIC-f polymer gel dose-response sensitivity irradiated by 1.25 MeV energy of cobalt-60. To investigate the dose-dependent polymerization, ultrasonic parameters of propagation speed of sound and broadband ultrasound attenuation coefficient were evaluated. To read-out of the radiation-in...
متن کاملBridging the ‘Two Cultures’ of Research and Service: Can Complexity Theory Help?; Comment on “Experience of Health Leadership in Partnering With University-Based Researchers in Canada – A Call to ‘Re-imagine’ Research”
This commentary addresses Bowen et al’s empirical study of perspectives of Canadian healthcare staff towards research and their call for multi-faceted action to improve misalignments in the system. This commentary argues that tensions and misalignments between research and service are inherent and can never be eradicated. Building on previous work by Lanham et al, I pro...
