When discretionary boundary spanning relationships cease becoming discretionary: The impact of closed ties on informal leadership perceptions.

Organizations have recognized that effective informal leadership is a source of competitive advantage and invest heavily in leadership development efforts. Moreover, because of historical shifts in the nature of work, this informal leadership often takes the form of inter-unit boundary spanning. Because of these two developments, discretionary boundary spanning (DBS) between units has increasingly become a critical, dynamic, bottom-up activity where individuals lacking formal authority step up and take on informal leadership responsibilities.

Wearable bluetooth sensors for capturing relational variables and temporal variability in relationships: A construct validation study.

The advent of wearable sensor technologies has the potential to transform organizational research by offering the unprecedented opportunity to collect continuous, objective, highly granular data over extended time periods. Recent evidence has demonstrated the potential utility of Bluetooth-enabled sensors, specifically, in identifying emergent networks via colocation signals in highly controlled contexts with known distances and groups. Although there is proof of concept that wearable Bluetooth sensors may be able to contribute to organizational research in highly controlled contexts, to date there has been no explicit psychometric construct validation effort dedicated to these sensors in field settings.
