“Feeling in Control”: Optimal Busyness and the Temporality of Organizational Controls

This study extends prior research seeking to understand the reproduction and persistence of excessive busyness in professional settings by addressing the relationship between organizational controls and temporal experiences. Drawing on 146 interviews and more than 300 weekly diaries in two professional service firms, we develop a framework centered on the emerging concept of optimal busyness, an attractive, short-lived temporal experience that people try to reproduce/prolong because it makes them feel energized and productive as well as in control of their time. Our findings show that individuals continuously navigate between different temporal experiences separated by a fine line, quiet time, optimal busyness, and excessive busyness, and that optimal busyness that they strive for is a fragile and fleeting state difficult to achieve and maintain. We show that these temporal experiences are the effect of the temporality of controls—that is, the ability of controls to shape professionals’ temporal experience through structuring, rarefying, and synchronizing temporality. Moreover, we find that professionals who regularly face high temporal pressures seek to cope with these by attempting to construct/prolong optimal busyness through manipulating the pace, focus, and length of their temporal experiences, a process we call control of temporality. Our study contributes to a better understanding of the reproduction of busyness by explaining why professionals in their attempts to feel in control of their time routinely end up overworking.

Multiparty Call Control at the Network Edge

Network programmability is a key feature of fifth generation (5G) system which, in combination with cloud-based services, can support many use cases, including mission critical and healthcare communications. Programmability enables flexibility in customization of service connectivity. Multi-access Edge Computing (MEC) services and applications are enablers for network programmability. In this paper, MEC capabilities for programmability of multiparty multimedia call control at the network edge are studied. Multiparty video calls are one of the key applications of 5G, and are efficient way to exchange ideas, knowledge, expertise, information, and so on. The paper presents an approach to design MEC Application Programming Interfaces (APIs) which enable third party applications to create multiparty multimedia sessions and dynamically manage session participations. The API functionality is described by required information and message flows. The paper specifies the proposed MEC API with data model. Feasibility study includes modelling and formal validation of multiparty session state models supported by the network and mobile edge application. The latency injected by the API is evaluated by emulation.

The Weaknesses of Weak Preemptionism

According to preemptionism, a layperson should treat the fact that an epistemic authority believes p as a reason to believe p that replaces her other reasons relevant to believing p and is not simply added to them. Many authors have found the unqualified version of preemptionism, as defended by Linda Zagzebski, too strong. At the same time, a number of them have recently advocated weakened or qualified preemptionist accounts. In this paper, I criticise these accounts. I argue that some of them cannot explain the possibility of rational persistent disagreements between laypeople and epistemic authorities, while those that can explain it fail to account either for the extent to which justification is a holistic phenomenon or for the role of what I call ‘control reasons’ in the laypeople's epistemic conduct.
