Abstract
Purpose
Since first small personal exposimeters became available, some studies have characterized personal exposition to radio frequency electromagnetic fields. The effect of body and relative position of the exposimeter have been also analyzed but some questions are still unanswered. The paper aims to discuss these issues.
Design/methodology/approach
Using three personal exposimeters in four different subjects, the authors characterized and compared measurements in a controlled experiment.
Findings
The authors found statistically significance differences between exposimeters and subjects due to relative position (right and left) and a control position far from the body (center). It should indicate that body and relative position of the exposimeter affect directly to the measurement, conditioning final and average results.
Research limitations/implications
Measurements using personal exposimeters have to be reconsidered and controlled.
Originality/value
The authors test personal exposimeters limitations in real conditions.

Abstract
Taking as reference a sample of around a hundred biographical materials on entrepreneurs in Mexico and Colombia, the purpose of this chapter is dual. Both to show the relevance and varied modalities that the biographical approach has enjoyed in business history research since the 1990s, and to display the intrinsic potential this modality of scholarship entails for entrepreneurship endeavors. In particular, it discusses the prospects to incorporate this body of empirical works into the large Latin American audience attending undergraduate, graduate and executive education programs in business, economic history and related fields. The chapter is organized into three sections. The first two are devoted to illustrate relevant patterns in the entrepreneurial trajectory of individuals and entrepreneurial families studied in each of the two countries under consideration. The last section identifies some conceptual issues that may impact current debates on Latin American business development as exemplified in recent business and economic history journal venues and scholarly conferences.
