True navigation in birds: from quantum physics to global migration

Birds are capable of true navigation, the ability to return to a known goal from a place they have never visited before. This is demonstrated most spectacularly during the vast migratory journeys made by these animals year after year, often between continents and occasionally global in nature. However, it remains one of the great unanswered questions in science, despite more than 50 years of research in this field. Nevertheless, the study of true navigation in birds has made significant advances in the previous 20 years, in part thanks to the integration of many disciplines outside its root in behavioural biology, to address questions of neurobiology, molecular aspects, and the physics of sensory systems and environmental cues involved in bird navigation, often involving quantum physics. However, true navigation remains a controversial field, with many conflicting and confusing results making interpretation difficult, particularly for those outside or new to the field. Unlike many general texts on migration, which avoid discussion of these issues, this review will present these conflicting findings and assess the state of the field of true navigation during bird migration.

The management of workplace conflict: Contrasting pathways in the HRM literature.

This paper reviews the human resource management literature on the management of workplace conflict. It suggests that workplace conflict is commonly viewed in the literature as a symptom of management failure: the notion that conflict may be intrinsic to the nature of work because employees and managers have hard-to-reconcile competing interests is given short-shrift. At the same time, the paper identifies important differences in the literature, which the authors call ‘pathways’, about the best methods to manage problems at the workplace. It is argued that four contrasting pathways can be detected in the literature with regard to how organizations approach workplace conflict management practices. Each pathway is examined fully and their respective strengths and weaknesses are assessed.
