Dynamics of Collective Sensemaking and Social Structuring Action Nets: An Organizational Ethnography Within the Military Health System's Defense Centers of Excellence for Psychological Health and Traumatic Brain Injury

Organizational perception and conception of interactions and relationships vary over time and space. This study focused on the capacity within and between healthcare organizations to collectively make sense of ambivalent and ambiguous environments in the context of social structuring actions (Czarniawska, 2008; Johnson, 2009; Weick, 1995). The purpose was to develop narrative frames from which a deeper understanding could be developed of how collective sensemaking is enacted through reciprocal and reflective interorganizational relationships during the final phases of an intended multiorganizational integration endeavor (Barki & Pinsonneault, 2005; Oliver, 1990). This study explored and described collective sensemaking as recognizable patterned social structuring actions that surfaced during integration efforts within the Military Health System's Defense Centers of Excellence for Psychological Health and Traumatic Brain Injury. A narrative approach illustrated emergent social processes. In the process of collaboration, ongoing generative conversations (Taylor & Van Every, 2000; Hardy, Lawrence, & Grant, 2005; Weick, 2004) affected the relationships between collective sensemaking and social structuring. An interpretive constructionist perspective revealed practices involving the interplay of assignment of meaning (signification), reducing equivocality and integration; formation of a sense of community, establishing structures and norms (legitimation); and the effects of collaboration and power (domination) distribution (Giddens, 1984; Weick, Sutcliffe, & Obstfeld, 2005). More than 24 months of embedded observation aided the researcher's awareness of ongoing narrative dynamics of collaborative actions setting the conditions for the emergence of interorganizational relationships (Harquail & King, 2010; Hatch, 1997; Hatch & Schultz, 2002) and embodied practices (Varela, Thompson, & Rosch, 1991). Throughout experiences of collective sensemaking, organizations interpose mini-narratives as evidence of reciprocal patterns of social structuring revealing cooperative behaviors interweaving coordinated actions and setting conditions for the structuring of collaborative integrating nets of collective action. This supports both Carniawska's (2008) and Weick's (1995) theory of organizing during collective sensemaking as enacted processes within relational conceptualizations and perceptions. These findings contribute to understanding the dynamics of collective sensemaking and social structuring; moreover, they incorporate the new paradigm of enaction (Kuhn, 1996; Stewart, Gapenne, & Di Paolo, 2010) as embodied sensemaking into organizational theory

JSAC, Special Issue on High-Performance Optical/Electronic Switches/routers for High-Speed Internet The European IST Project DAVID: a Viable Approach towards Optical Packet Switching

Abstract — In this paper promising technologies and a network architecture are presented for future Optical Packet Switched networks. The overall network concept is presented and the major choices are highlighted and compared with alternative solutions. Both long and shorter term approaches are considered as well as both the WAN and MAN parts of the network. The results presente

Komponenten, Systemkonzepte und Demonstratoren fuer die optische Signalverarbeitung (Photonik OSV)

Objective of the project has been the development of system concepts and the realisation of key components and sub systems for central areas of optical signal processing. Methods have been elaborated for the application of space and wavelength multiplex techniques enabling routing and switching of optical signals (up to 10 Gbit/s) in future optical broadband core and access networks. The required key components wavelength converter, space switch units and wavelength tuneable filters have been developed. After realisation of a global concept for optical nodes in the core and access area (based on broadcast and select) detailed concepts have been worked out for the realisation of optical cross connects for 2.5 and 10 Gbit/s signals. Investigations have been performed on signal formats as well as on operation, administration and maintenance in optical transparent routing nodes. Realisation concepts have been developed for the key components wavelength converter and blocking free space switch units, resulting in devices well suited and used for demonstrator applications. For tuneable optical filters a new concept was developed based on the introduction of fractal optical gratings. By means of optical 10 Gbit/s cross connect cascading experiments of optical nodes were performed. No significant deterioration of the system sensitivity was observed for optical signals fed through several cascaded cross connects. Thus, the suitability of the proposed approach for optical cross connects (up to 10 Gbit/s) and the cascading to larger routing blocks was verified. For the access regime, optical routing of digital multi-level modulated signals in space and wavelength has been demonstrated for the first time.

Norms of Professional Behavior in Highly Speclalized Organizations: The Case of American Zoos and Aquariums

Three attitude dimensions are apparent among zoological managers. They concern professional ethics, organization, and responsibility toward animals. In this article, four models of the acceptance of professional norms are tested, and career-related goals are found to be the best predictors of such attitudes. Noneconomic goals seem to promote zoological professionalism, whereas entrepreneurial activities reduce support for generally accepted norms of behavior. The implications of these findings and possibilities for further research are discussed.Yeshttps://us.sagepub.com/en-us/nam/manuscript-submission-guideline
