The G-20 and International Financial Institution Governance
No full textThis paper addresses the agenda for the Group of Twenty (G-20) leaders' meeting in Seoul, Korea in November 2010. This is an opportunity and challenge for Asian leaders in particular. Their test will be, first, to demonstrate that they can responsibly advance economic recovery. They must also deliver on institutional reform, in particular of the International Monetary Fund (IMF). Author Edwin M. Truman advocates a substantial expansion of the IMF's role as lender of last resort that is integrated with the surveillance role of the IMF in the form of comprehensive prequalification for IMF assistance and policy advice and a substantial increase in the IMF's financial resources. Truman also propose an approach to meaningful reform of the distribution of IMF quotas along with limiting European seats on the IMF executive board.International Monetary Fund, Group of Twenty G20, China, Korea, Asia, special drawing rights, economic growth, exchange rates
A flexible bimodal model with long-term survivors and different regression structures
No full textThe cure fraction models are useful to model lifetime data with long-term survivors. In this paper, we introduce a flexible cure rate survival model where the model parameters are related to covariates in different regression structures. The regression model allows to model jointly the location, scale and shape effects. The maximum likelihood method is employed to estimate the model parameters. We provide Monte Carlo simulation experiments to verify the performance of the maximum likelihood estimates for different sample sizes and cure rate percentages. Furthermore, some diagnostic measures to assess departures from model assumptions as well as to detect outlying observations are also considered. Finally, applications to real data are presented to show the usefulness of the new cure rate model.Lemonte, AJ (corresponding author), Univ Fed Rio Grande do Norte, Dept Stat, Rio Grande Do Norte, RN, Brazil.

Boys of England and Edwin J. Brett, 1866-99
No full textBoys of England was a Victorian boys' periodical. It was published weekly by Edwin J. Brett from 1866 to 1899, initially from the Fleet Street offices of the Newsagents'
Publishing Company, and later from Brett's own `Boys of England Office'. It was the first periodical of its kind, and achieved a large sale amongst eager youngsters.
The purpose of this thesis is to provide a general history of BOE and Brett, neither of which has yet been attempted. More specifically, the thesis is intended to address
misconceptions regarding Brett and his work. Historians of boys' periodical literature have tended to portray Brett's papers as largely supportive of middle class hegemony. They
argue that they failed to connect with the lives of their upper working and lower middle class readers. However, this thesis contends that in actual fact BOE engaged closely with
the lives of its readership, comprised mainly of boys from the `respectable' working classes. Therefore, BOE should rightly be considered an important, indigenous component
of working class society and culture in mid to late Victorian Britain.
To provide as comprehensive an analysis as possible, the thesis is divided into three sections: `Paper and Proprietor'; `Content'; `Response'. These sections are divided into further chapters, each exploring a salient facet of BOE and Brett. Some of these engage with, and challenge, the existing historiography of boys' periodical literature. Others introduce historiographies previously remote from the study of boys' papers, widening the
remit of this relatively self-contained field. Some examine entirely unstudied, or largely understudied, subject matter.
Ultimately, this thesis is intended to make a valuable contribution not only to the historiography of boys' papers specifically, and children's literature in general, but also to the wider historiographies of Victorian social and cultural history and the Victorian working class
Academic authorship: who, why and in what order?
No full textWe are frequently asked by our colleagues and students for advice on authorship for scientific articles. This short paper outlines some of the issues that we have experienced and the advice we usually provide. This editorial follows on from our work on submitting a paper1 and also on writing an academic paper for publication.2 We should like to start by noting that, in our view, there exist two separate, but related issues: (a) authorship and (b) order of authors. The issue of authorship centres on the notion of who can be an author, who should be an author and who definitely should not be an author, and this is partly discipline specific. The second issue, the order of authors, is usually dictated by the academic tradition from which the work comes. One can immediately envisage disagreements within a multi-disciplinary team of researchers where members of the team may have different approaches to authorship order
Field notes of John Paul Newey on a study area east of Little Granite Mtn. and elsewhere
No full textManuscript dating from the late 1940s or 1950, prior to author\u27s service in the Korean War, with accompanying note dated March 13, 1956 by A. M. Woodbury, stating that "these notes were never completely organized for publication" before Newey left the field of science, and were subsequently used by Mark Edwin Rosasco in a later study
Plasma position control in the STOR-M tokamak : a fuzzy logic approach
No full textAdequate control of the position of the plasma column within the STOR-M tokamak is a chief requirement in order for experimental quality discharges to be obtained. Optimal control over tokamak discharge parameters, including the plasma position, is very difficult to achieve. This is due in large part to the difficulty in modelling the tokamak discharge parameters, as they are highly nonlinear and time varying in nature. The difficulty of modelling the tokamak discharge parameters suggests that a control system, such as a fuzzy logic based controller, which does not require a system model may be well suited to the control of fusion plasma.
In order to improve the quality of control over the plasma position within the STOR-M tokamak, the existing analog PID controller was modified. These modifications facilitate the application of a digital controller by a personal computer via the Advantech PCL-711B data acquisition card. The performance of the modified plasma position controller and an Arbitrary Signal Generator developed by the author was evaluated. This modified plasma position controller was applied successfully to the STOR-M tokamak during both normal mode and A.C. mode operation. In both cases, the modified controller provided adequate control over the position of the plasma column within the discharge chamber. Furthermore, the modified controller was more convenient to optimize than the original, existing analog PID controller.
By taking advantage of the modifications that were made to the plasma position controller, a fuzzy logic controller was developed by the author. The fuzzy logic based plasma position controller was also successfully applied to the STOR-M tokamak during both normal mode and A.C. operation. The fuzzy controller was demonstrated to reliably provide a higher degree of control over the position of the plasma column within the STOR-M tokamak than the modified PID controller

ImageMiner : an architecture to support deep mining of images
No full textThesis: M. Eng. in Computer Science and Engineering, Massachusetts Institute of Technology, Department of Electrical Engineering and Computer Science, 2015.This electronic version was submitted by the student author. The certified thesis is available in the Institute Archives and Special Collections.Cataloged from student-submitted PDF version of thesis.Includes bibliographical references (pages 69-70).In this thesis, I designed a cloud based system, called ImageMiner, to tune parameters of feature extraction process in a machine learning pipeline for images. Feature extraction is a key component of the machine learning pipeline, and tune its parameters to extract the best features can have significant effect on the accuracy achieved by the machine learning system. To enable scalable parameter tuning, I designed a master-slave architecture to run on the Amazon cloud. To overcome the computational bottlenecks due to large datasets, I used a data parallel approach where each worker runs independently on a subset of data. The worker uses a Gaussian Copula Process to tune parameters and determines the best set of parameters and model to use.by Edwin Meng Zhang.M. Eng. in Computer Science and Engineerin
