Institutional Fragility and E‐Business Adoption: A Study of SMEs in a Conflict‐Affected Economy
Strategic Change, EarlyView.ABSTRACT This study examines e‐business adoption among SMEs in Yemen, a conflict‐affected and institutionally fragile economy. Drawing on a mixed‐methods design, it combines Partial Least Squares Structural Equation Modelling (PLS‐SEM) with qualitative interviews to analyse how war and firm size moderate the effects of key adoption drivers and barriers.

Asymptotic outage performance of power allocation in block-fading channels
, 2008 We characterize the asymptotic outage performance of power allocation techniques for systems with average power constraints. We show that the outage diversity of a system with average power constraints can be obtained from the diversity of the ...

Psychology &Marketing, EarlyView.ABSTRACT Loneliness shapes consumer behavior, yet whether it increases preference for warm or competent brands remains unresolved. We argue that this question cannot be answered without distinguishing who is perceived to be lonely. Individual loneliness, which is a person's subjective experience of social disconnection, activates agency‐restoration ...

Stabilising Routines in Complex Emergencies: How Basic Service Continuity Shapes Perceived Security
Public Administration and Development, EarlyView.ABSTRACT This study examines how locally embedded actors describe the relationship between basic service continuity and perceived security in complex emergencies, with particular attention to the stabilisation of everyday routines. Using Proximity‐Predictability‐Attributability (PPA) as an analytic lens, we trace how interviewees relate access to water,
