Perspectives of healthcare workers on integrated management of childhood illness in Pakistan: A phenomenological approach
(
SAGE
, 2024 , Article)
In 2019, an estimated 5.2 million deaths were reported among children less than 5 years of age. At primary healthcare level, healthcare workers (HCWs) mostly rely on history and clinical findings and less on inadequate ...
The Affordances of Strategy Mapping
(
Academy of Management
, 2023 , Article)
Little research has focused on the role of strategy map and its affordances when developing a joint account of strategy in the context of a multidivisional organization. Building on the Strategy-As-Practice (SAP) research ...
