Developments in professional practice can be related to ongoing changes in relations of power among professionals, which often lead to changes in the boundaries of practices. The differing contexts of practices also influence these changing relations among health professionals. Legislation governing professional practice also differs from country to country. In Brazil, over the past 12 years, in a climate of deep disagreement, a new law to regulate medical practice has been discussed. It was sanctioned, or made into law, but with (...) some notable changes, in July 2013. Of interest to us in this paper are the ways the proposed legislation, by setting out the boundaries and scope of medical practice, ‘interfered’ in the practices of other health professions, undermining many ‘independent’ practices that have developed over time. However, even taking into account the multiple routes through which practices are established and developed, the role of legislation that seems able to contradict and deny the historical realities of multiple, intersecting practices should be critically interrogated. In this paper, we use the theoretical resources of poststructuralist thinking to explore gaps, ambiguities, and power relations implicit in the discourses that constituted this law. We argue that although the new law can be understood as a social and political device that will interfere in the organization of other health professions’ practices, such legislation is only part of what constitutes change in a consolidated professional practice. And while it is important to understand the effects of such legislation, healthcare practices are also realized or ‘made real’ through ongoing relations of knowledge and power, including, as we will see in this case, activities of resistance. The problem, then, is to understand the practical arrangements, including legislation, traditions and routines, values and knowledge that come to shape the practices of nursing in a particular context.

In this paper, we make explicit the changing configurations of power relations that currently characterize the Brazilian Emergency Care System (SAMU) team in Belo Horizonte, Brazil. The SAMU is a recent innovation in Brazilian healthcare service delivery. A qualitative case study methodology was used to explore SAMU’s current organizational arrangements, specifically the power relations that have developed and that demonstrate internal team struggles over space and defense of particular occupational interests. The argument advanced in this paper is that these professionals (...) are developing their work in conditions of exposure, that is, they are always being observed by someone, and that such observational exposure provides the conditions whereby everyday emergency care practices are enacted such that practice is shaped by, as well as shapes, particular, yet recognizable power relationships. Data were collected through the observation of the SAMU’s work processes and through semi‐structured interviews. Research materials were analyzed using discourse analysis. In the emergency care process of work, visibility is actually embedded in the disciplinary context and can thus be analyzed as a technique applied to produce disciplined individuals through the simple mechanisms elaborated by Foucault such as hierarchical surveillance, normalizing judgment, and the examination.

To understand power relations, it is important to consider that power is an attribute, and whoever has it at a given moment is in the condition of dominant and whoever is under its exercise is dominated. Moreover, we must consider that these positions are interchangeable, changing when relations of force change. Power relations represent the pursuit of supremacy through knowledge, with struggles for better positioning in the social structure. In this study, we analyze the effects of disciplinary power on daily (...) practices of nurses and physicians in the hospital environment, more specifically in intensive care units. From the perspective of disciplines, power is exercised in a discreet, modest, calculated and permanent way, through the establishment of rules and norms. In this context, despite the strong appreciation of a medical‐centered model, it is observed that nurses gain visibility through knowledge and the defense of institutional norms and rules, which can generate tensions in daily professional practices.

It is widely recognized that police performance may be hindered by psychophysiological state changes during acute stress. To address the need for awareness and control of these physiological changes, police academies in many countries have implemented Heart-Rate Variability biofeedback training. Despite these trainings now being widely delivered in classroom setups, they typically lack the arousing action context needed for successful transfer to the operational field, where officers must apply learned skills, particularly when stress levels rise. The study presented here aimed (...) to address this gap by training physiological control skills in an arousing decision-making context. We developed a Virtual-Reality breathing-based biofeedback training in which police officers perform deep and slow diaphragmatic breathing in an engaging game-like action context. This VR game consisted of a selective shoot/don’t shoot game designed to assess response inhibition, an impaired capacity in high arousal situations. Biofeedback was provided based on adherence to a slow breathing pace: the slower and deeper the breathing, the less constrained peripheral vision became, facilitating accurate responses to the in-game demands. A total of nine male police trainers completed 10 sessions over a 4-week period as part of a single-case experimental ABAB study-design. Results showed that eight out of nine participants showed improved breathing control in action, with a positive effect on breathing-induced low frequency HRV, while also improving their in-game behavioral performance. Critically, the breathing-based skill learning transferred to subsequent sessions in which biofeedback was not presented. Importantly, all participants remained highly engaged throughout the training. Altogether, our study showed that our VR environment can be used to train breathing regulation in an arousing and active decision-making context. (shrink)

This target article draws together two groups of experimental studies on the control of human movement through peripheral feedback and centrally generated signals of motor commands. First, during natural movement, feedback from muscle, joint, and cutaneous afferents changes; in human subjects these changes have reflex and kinesthetic consequences. Recent psychophysical and microneurographic evidence suggests that joint and even cutaneous afferents may have a proprioceptive role. Second, the role of centrally generated motor commands in the control of normal movements and movements (...) following acute and chronic deafferentation is reviewed. There is increasing evidence that subjects can perceive their motor commands under various conditions, but that this is inadequate for normal movement; deficits in motor performance arise when the reliance on proprioceptive feedback is abolished either experimentally or because of pathology. During natural movement, the CNS appears to have access to functionally useful input from a range of peripheral receptors as well as from internally generated command signals. The unanswered questions that remain suggest a number of avenues for further research. (shrink)

The book analyzes how one might philosophize about some of the most difficult and controversial issues in ethics and politics without abandoning either the demands of rigor or the joys of clear vistas.
