Health workforce indicators?1 Those should be easy. We just need to count the numbers entering from training institutions or through re-entry, the numbers working, and the numbers exiting. If we know where these people work, we have the distribution of health workers within a country, and if we also have information on their competencies, responsiveness and productivity, we can know about their...

As the world recovers from the worst economic crisis since the Great Depression, the international community should promote a mix of policies to sustain this global recovery and create jobs through reducing carbon dependency, ecological degradation and poverty. Such a Global Green New Deal (GGND) requires a long-term commitment to implementing and coordinating “green investments” by the Group o...

In order to implement eeciently in software block ciphers, advanced bitslicing techniques (such as those described by Bihamm1]) may be used. However, these techniques lead to a slow development process, and the resulting code is hard to maintain. We describe here a compiler that takes a formal description of an algorithm and outputs C code implementing it in an optimized way.

This article traces the history of machine-readable data encoding standards and argues that QR code has become an infrastructural gateway. Through analysis patents, corporate documents advertising, ethnographic observations, interviews with professionals, I describe global making argue convergence standards, mobile computing, machine vision algorithms, platform ecosystems led to emergence a new...

An identifying code in a graph is a subset of vertices having a nonempty and distinct intersection with the closed neighborhood of every vertex. We prove that the infimum density of any identifying code in Sk (an infinite strip of k rows in the square grid) can always be achieved by a periodic identifying code with pattern length at most 2. Assisted by a compute program implementing Karp’s algo...

PURPOSE OF THE STUDY A key directive of the Affordable Care Act of 2010 is to transform both institutional and community-based long-term care into a more person-centered system. In the nursing home industry, the culture change movement is central to this shift in philosophy. If policymakers are to further encourage implementation of culture change, they need to better understand the factors ass...

Cyclone is a type-safe programming language that provides explicit run-time code generation. The Cyclone compiler uses a template-based strategy for run-time code generation in which pre-compiled code fragments are stitched together at run time. This strategy keeps the cost of code generation low, but it requires that optimizations, such as register allocation and code motion, are applied to te...

We provide a description of the SNSPH code—a parallel 3-dimensional radiation hydrodynamics code implementing treecode gravity, smooth particle hydrodynamics, and flux-limited diffusion transport schemes. We provide descriptions of the physics and parallelization techniques for this code. We present performance results on a suite of code tests (both standard and new), showing the versatility of...
