The concept of self-care is multidimensional, with many defining elements. This paper describes the origin of this comprehensive concept. It examines the response of the nursing discipline to citizen self-care initiatives and the subsequent effects this response has had on the development of nursing knowledge. The evolution of self-care as a core concept within Canadian health policy is present...

A methodology for development of intelligent user interfaces is presented which allows for programming by correcting behavior, rather than writing programs or scripts. The importance of incremental knowledge accumulation with contributing individuals cooperating over the network is pointed out. The experience of the authors with the prototype of an interface builder and prelimnary results are o...

A version of this paper was given as the 2008 Economica Phillips Lecture at LSE on February 7, 2008. I thank Francesco Caselli and other participants in that event for their comments. I am also grateful for conversations with Fernando Alvarez, Jess Benhabib, Francisco Buera, Jonathan Eaton, James Heckman, Boyan Jovanovic, Sam Kortum, Cassey Mulligan, and Nancy Stokey, and for the assistance and...

Sashka’s Technique applied to pFBP The key step in Sashka and Russel’s technique to prove lower bounds for pFBT was to prove that for each path p of length l, PrI [S(I) ⊢ PSp | I ⊢ PIp] ≤ 1 f . We extend this to a technique for pFBP. The key step is to prove that for each node v at depth l, PrI [S(I) ⊢ PSv | I ⊢ PIv] ≤ 1 f . My intuition was that PrI [S(I) ⊢ PSv | I ⊢ PIv] ≤ maxp∈v PrI [S(I) ⊢ ...

Governments and foundations have successfully harnessed tournaments to spur innovation. Yet this tool is not widely used by firms. We offer a framework for managers seeking to organize tournaments for ideas. We present the theoretical underpinnings of tournaments. We then connect the theory with three recent innovations—the power of the network, the wisdom of crowds, and the power of love—that ...

An experiment is a test that involves manipulating some factor in a system in order to see how that affects the outcome. Ideally, experiments also involve controlling as many other factors as possible in order to isolate the cause of the experimental results. Experiments can be quite simple tests set up in a lab—like rolling a ball down different inclines to see how the angle affects the rollin...

The notion of innate ideas has long been the subject of intense debate in the fields of philosophy and cognitive science. Over the past few decades, methodological advances have made it possible for developmental researchers to begin to examine what innate ideas—what innate concepts and principles—might contribute to infants’ knowledge acquisition in various core domains. This article focuses o...

Plagiarism is a crime against academy. It deceives readers, hurts plagiarized authors, and gets the plagiarist undeserved benefits. However, even though these arguments do show that copying other people's intellectual contribution is wrong, they do not apply to the copying of words. Copying a few sentences that contain no original idea (e.g. in the introduction) is of marginal importance compar...

It is widely acknowledged that 3-D mesh generation remains one of the most man-hours consuming techniques within computational mechanics. The problem of mesh generation is that the time remains unbounded, even using the most sophisticated mesh-generator. For a given distribution of points, it is possible to obtain a mesh very quickly, but it may require several iterations, including manual inte...
