Diversity in an Anti-immigration Era: Theories, controversies, principles

Immigration and product diversity

We study the effects of immigration on the diversity of consumption choices. Data from California in the 1990s indicate that immigration is associated with fewer stand-alone retail stores and a greater number of large and in particular big-box retailers—evidence that likely contradicts a diversityenhancing effect of immigration. In contrast, focusing on the restaurant sector for which we can be...

Working memory: theories, models, and controversies.

I present an account of the origins and development of the multicomponent approach to working memory, making a distinction between the overall theoretical framework, which has remained relatively stable, and the attempts to build more specific models within this framework. I follow this with a brief discussion of alternative models and their relationship to the framework. I conclude with specul...

Advantages and controversies in the era of intrarenal volumetry.

BACKGROUND/AIMS Ultrasound is the preferred imaging modality in nephrology. In many kidney diseases, however, more accurate methods are needed to distinguish between relevant intrarenal structures. MRI could be a solution, although the use of MRI contrast has caused severe complications in some cases, and invasive kidney biopsies may follow, even though such small specimens traditionally provid...

Introduction: studying diversity in an era of ubiquitous genomics

Just as scientific discoveries enable the development of new technology, novel technologies can drive scientific progress. Similar to the adoption of PCR as a mainstream laboratory technique in the 1990s, the ability to readily sequence whole genomes today has opened up new areas of biology and fundamentally changed the way people work in existing fields. The most obvious feature of so-called ‘...
