The editorial by Jeremy Shiffman, “Knowledge, moral claims and the exercise of power in global health”, highlights the influence on global health priority-setting of individuals and organizations that do not have a formal political mandate. This sheds light on the way key functions in global health depend on private funding, particularly from the Bill & Melinda Gates Foundation.

The paper presents a simple yet robust measure of image quality in terms of global (camera) blur. It is based on histogram computation of non-zero DCT coe cients. The technique is directly applicable to images and video frames in compressed (MPEG or JPEG) domain and to all types of MPEG frames (I-, Por Bframes). The resulting quality measure is proved to be in concordance with subjective testin...

Shiffman has argued that some actors have a great deal of power in global health, and that more reflection is needed on whether such forms of power are legitimate. Global health is a new and evolving field that builds upon the historical fields of public and international health, but is more multi-disciplinary and inter-disciplinary in nature. This article argues that the distribution of power ...

In this comment, I build on Shiffman’s call for the global health community to more deeply investigate structural and productive power. I highlight two challenges we must grapple with as social scientists carrying out the types of investigation that Shiffman proposes: the politics of  challenging the powerful; and the need to investigate types of expertise that have traditionally been thought o...

The year 2016 could turn out to be a turning point for global health, new political realities and global insecurities will test governance and financing mechanisms in relation to both people and planet. But most importantly political factors such as the global power shift and “the rise of the rest” will define the future of global health. A new mix of health inequity and security challenges has...

New contours of global inequality present new challenges for global health, and require that we consider new kinds of health issues as global. I provide a number of illustrations, arguing the need for a political science of health that goes beyond conventional preoccupations with formal institutional and interstate interactions and takes into account how globalization has affected the health po...

In this note, the notion of generalized continuous K- frame in a Hilbert space is defined. Examples have been given to exhibit the existence of generalized continuous $K$-frames. A necessary and sufficient condition for the existence of a generalized continuous $K$-frame in terms of its frame operator is obtained and a characterization of a generalized continuous $K$-frame for $ mathcal{H} $ wi...
