Whistleblowing by health professionals is an infrequent and extraordinary event and need not occur if internal voices are heard. Mannion and Davies’ editorial on “Cultures of Silence and Cultures of Voice: The Role of Whistleblowing in Healthcare Organisations” asks the question whether whistleblowing ameliorates or exacerbates the ‘deaf effect’ prevalent in healthcare organisations. This comme...

In their valuable discussion of whistleblowing in healthcare organisations, Mannion and Davies highlight the importance of organisational culture in influencing whether people raise concerns, and whether these concerns are listened to and acted upon. The role of leadership in shaping organisational culture is well-established1 and in this commentary, we will examine the influence of leaders in ...

Speech can be modeled as short bursts of vocal energy separated by silence gaps. During typical conversation, talkspurts comprise only 40% of each party’s speech and remaining 60% is silence. Communication systems can achieve spectral gain by disconnecting the users from the spectral resource during silence periods. This letter develops a simple and efficient Voice Activity Detection (VAD) algo...

In the healthcare context, whistleblowing has come to the fore of political, professional and public attention in the wake of major service scandals and mounting evidence of the routine threats to safety that patients face in their care. This paper offers a commentary and wider contextualisation of Mannion and Davies, ‘Cultures of silence and cultures of voice: the role of whistleblowing in hea...

Arguing from feminist and sociocultural theories, I make a distinction between being silenced and being silent; when being silenced is contrasted with voice, it is conceptualised as imposed, and it signifies ...

We highlight conversations at work as an arena of change. Drawing on and extending the psychological safety literature, we offer a new framework to distinguish between productive unproductive forms both voice silence. The framework’s four quadrants – withholding, disrupting, contributing processing outline essential activities in group that advance goals, including organization authors’ own res...

Mannion and Davies’ article recognises whistleblowing as an important means of identifying quality and safety issues in healthcare organisations. While ‘voice’ is a useful lens through which to examine whistleblowing, it also obscures a shifting pattern of uncertain ‘truths.’ By contextualising cultures which support or impede whislteblowing at an organisational level, two issues are overlooked...

This paper presents a new dynamically adaptable polling scheme for efficient support of voice communications over an IEEE802.11 network. The proposed Cyclic Shift and Station Removal polling scheme is implemented only on the Access Point of each Basic Service Set without requiring any modification on the existing access protocol. This polling scheme increases the number of conversations in case...
