Abstract
This paper summarises our work on policy-enabled inter-network routing for mobile networks and adapting information services to available networking resources in tactical networks. The work shows promise; both the policy routing and adaptive service infrastructure were part of successful interoperability trials in the Coalition Warrior Interoperability eXercise (CWIX) in 2021. This paper highlights our findings, how our work can support interoperability in NATO, and represents an enabler for future coalition operations. Although promising, the work involves research and concept development, and so, we anticipate its timeframe for seeing actual operational use as likely 3–5 years from now, typically targeting future developments within Federated Mission Networking (FMN). In our work, we have shown that we can build a federated mobile network by using a reactive routing protocol that supports policy routing in a network overlay for use in a coalition. Further, we have shown that we can leverage network-level information at the application level, through a so-called cross-layer optimization (CLO) approach. The CLO approach leverages a well-defined format, and we found that this format promotes interoperability and can be used in a multi-national setting. Since our work is experimental, we have also identified some shortcomings for future work.

AbstractChanging agricultural research and extension systems mean that informal mechanisms of information diffusion are often the primary source of information about improved seed and practices for farmers in sub‐Saharan Africa. This paper investigates the interactions between gender, social capital and information exchange in rural Uganda. Within the framework of farmer‐to‐farmer models, we conceptualise the informal information diffusion process to comprise social capital accumulation and information exchange. We assume that each agent participates in information exchange with a fixed (predetermined) level of social capital and examine how endowments of social capital influence information exchange, paying close attention to gender differences. A multinomial logit model is used to analyse multiple participation choices of information exchange facing the farmer. Findings demonstrate that social capital is an important factor in information exchange, with men generally having better access to social capital than women. We also find strong evidence in support of group‐based technology dissemination systems. Copyright © 2008 John Wiley & Sons, Ltd.

Groups rarely use the unique knowledge of their members when making decisions, focusing instead on knowledge that members have in common. This tendency to neglect the expertise of group members severely limits the effectiveness of group decision making. Previously, this problem has been addressed by showing that groups will pool task-relevant information and make effective decisions if members have knowledge of each other's expertise. However, these studies are generally limited because they disregard why people use each other's expertise once they are aware of it. The current study uses expectancy theory to investigate this issue and to link motivation to information exchange in groups. Results of a hidden profile study involving 40 groups indicated that expectancy motivation drives groups to use expertise awareness, exchange more unique information, and thus solve a hidden profile problem correctly.

This study examines information exchange and decision-making processes in small groups that interacted verbally orwitha group support system (GSS). Six-memberGSSand non-GSS groups worked to solve a hidden profile task in which members had different information and needed to share their information to discover the optimal decision. Both GSS and non-GSS groups exchanged only a small portion of the available information. Both made poor decisions because they lacked sufficient information and failed to effectively use the shared information. GSS groups were less likely to use the shared information, possibly because anonymity reduced the information's credibility or the GSS impaired members' abilities to integrate the newly received information into their existing base of information.

This article contributes to the design of a generic framework for providing a new way to exchange information between enterprises. This concept is a well addressed in the context of B2B standards. Many organizations are increasingly searching for adopting these standards to automate data exchange. But the limit of such models resides in the fact that the content of exchange is defined in several formats which make their use difficult. To overcome this difficulty, we have explored the possibility to integrate new models for describing content involved in B2B transaction which represent a key issue. Our finding establishes the feasibility of integrating product models described by ontology with e-commerce standards especially at the business process level. This article presents a descriptive model allowing partners to exchange information with other organisations without modifying their Information System. The case study also indicates that our system is developed as a Service Oriented Architecture.

Although information exchange among trading partners is consistently mentioned as a key requirement of successful supply chain management implementation, research on information exchange is scarce. This lack of research provides little guidance and support for those managers interested in improving their logistics operations through increased information exchange. The main goal of this paper is to identify potential antecedents of information exchange. Questionnaires were sent to logistics managers at manufacturing firms in several industries. The results of this exploratory study are detailed and the implications for logistics managers discussed.

The federal government allocated nearly $30 billion to spur the development of information technology infrastructure capable of supporting the exchange of interoperable clinical data, leading to growth in hospital participation in health information exchange (HIE) networks. HIEs have the potential to improve care coordination across healthcare providers, leading ultimately to increased productivity of health services for hospitals. However, the impact of HIE participation on hospital efficiency remains unclear. This dynamic prompts the question asked by this study: does HIE participation improve hospital efficiency. This study estimates the effect of HIE participation on efficiency using a national sample of 1017 hospitals from 2009 to 2012. Using a two-stage analytic design, efficiency indices were determined using the Malmquist algorithm and then regressed on a set of hospital characteristics. Results suggest that any participation in HIE can improve both technical efficiency change and total factor productivity (TFP). A second model examining total years of HIE participation shows a benefit of one and three years of participation on TFP. These results suggest that hospital investment in HIE participation may be a useful strategy to improve hospital operational performance, and that policy should continue to support increased participation and use of HIE. More research is needed to identify the exact mechanisms through which HIE participation can improve hospital efficiency.
