PSS are more user-friendly, but are they also increasingly useful?

Learning object repositories are useful, but are they usable?

Learning Object Repositories seems to be the solution to facilitate the sharing and reusing of learning material. As useful as they may appear, Learning Object Repositories are not in widespread use among faculty around the world. There are indications that the amount of work and time required to use the Repositories is the main reason for the reluctance of teachers. This work analyzes the tool...

Rank-based inverse normal transformations are increasingly used, but are they merited?

Many complex traits studied in genetics have markedly non-normal distributions. This often implies that the assumption of normally distributed residuals has been violated. Recently, inverse normal transformations (INTs) have gained popularity among genetics researchers and are implemented as an option in several software packages. Despite this increasing use, we are unaware of extensive simulat...

New cardiovascular risk factors exist, but are they clinically useful?

There is substantial interest in identifying new risk factors for cardiovascular disease, to improve our understanding of disease biology and to account for the cases of heart disease that cannot be explained by known risk factors. Investigation of putative risk factors frequently involves the study of circulating biomarkers. In recent years, a spirited debate has arisen regarding the validity ...

Flux Caches: What Are They and Are They Useful?

In this paper, we introduce the concept of flux caches envisioned to improve processor performance by dynamically changing the cache organization and implementation. Contrary to the traditional approaches, processors designed with flux caches instead of assuming a hardwired cache organization change their cache ”design” on program demand. Consequently program (data and instruction) dynamic beha...
