HOW CAN WE MANAGE COLLABORATION NETWORK VIA COMMUNICATION?
Now that a wide range of products and services are being commoditized globally, corporations are increasingly seeking to derive their competitiveness from the knowledge work of their staff. They are considering various measures, such as ways of management focusing on the organization of the company; among them is an approach in which knowledge born in the workplace is turned into organizational strength. More recently, indications are growing that social networks are also important. In reality, however, it is often the case that only information sharing is encouraged, and that the perspective of actually understanding a situation and thereby taking control of it is missing. This paper uses the example of company Y, which has been evaluated highly for its management utilizing ICT, and provides a quantitative association between communication and collaboration, thereby clarifying causal relationships. Based on the acquired results, we propose a management method, which allows the management of collaboration within a company by encouraging the networks of communication
Harnessing Collaborative Technologies: Helping Funders Work Together Better
This report was produced through a joint research project of the Monitor Institute and the Foundation Center. The research included an extensive literature review on collaboration in philanthropy, detailed analysis of trends from a recent Foundation Center survey of the largest U.S. foundations, interviews with 37 leading philanthropy professionals and technology experts, and a review of over 170 online tools.The report is a story about how new tools are changing the way funders collaborate. It includes three primary sections: an introduction to emerging technologies and the changing context for philanthropic collaboration; an overview of collaborative needs and tools; and recommendations for improving the collaborative technology landscapeA "Key Findings" executive summary serves as a companion piece to this full report
Socially Trusted Collaborative Edge Computing in Ultra Dense Networks
Small cell base stations (SBSs) endowed with cloud-like computing
capabilities are considered as a key enabler of edge computing (EC), which
provides ultra-low latency and location-awareness for a variety of emerging
mobile applications and the Internet of Things. However, due to the limited
computation resources of an individual SBS, providing computation services of
high quality to its users faces significant challenges when it is overloaded
with an excessive amount of computation workload. In this paper, we propose
collaborative edge computing among SBSs by forming SBS coalitions to share
computation resources with each other, thereby accommodating more computation
workload in the edge system and reducing reliance on the remote cloud. A novel
SBS coalition formation algorithm is developed based on the coalitional game
theory to cope with various new challenges in small-cell-based edge systems,
including the co-provisioning of radio access and computing services,
cooperation incentives, and potential security risks. To address these
challenges, the proposed method (1) allows collaboration at both the user-SBS
association stage and the SBS peer offloading stage by exploiting the ultra
dense deployment of SBSs, (2) develops a payment-based incentive mechanism that
implements proportionally fair utility division to form stable SBS coalitions,
and (3) builds a social trust network for managing security risks among SBSs
due to collaboration. Systematic simulations in practical scenarios are carried
out to evaluate the efficacy and performance of the proposed method, which
shows that tremendous edge computing performance improvement can be achieved.Comment: arXiv admin note: text overlap with arXiv:1010.4501 by other author
Secure and Trustable Electronic Medical Records Sharing using Blockchain
Electronic medical records (EMRs) are critical, highly sensitive private
information in healthcare, and need to be frequently shared among peers.
Blockchain provides a shared, immutable and transparent history of all the
transactions to build applications with trust, accountability and transparency.
This provides a unique opportunity to develop a secure and trustable EMR data
management and sharing system using blockchain. In this paper, we present our
perspectives on blockchain based healthcare data management, in particular, for
EMR data sharing between healthcare providers and for research studies. We
propose a framework on managing and sharing EMR data for cancer patient care.
In collaboration with Stony Brook University Hospital, we implemented our
framework in a prototype that ensures privacy, security, availability, and
fine-grained access control over EMR data. The proposed work can significantly
reduce the turnaround time for EMR sharing, improve decision making for medical
care, and reduce the overall costComment: AMIA 2017 Annual Symposium Proceeding
An active, ontology-driven network service for Internet collaboration
Web portals have emerged as an important means of collaboration on the WWW, and the integration of ontologies promises to make them more accurate in how they serve users’ collaboration and information location requirements. However, web portals are essentially a centralised architecture resulting in difficulties supporting seamless roaming between portals and collaboration between groups supported on different portals. This paper proposes an alternative approach to collaboration over the web using ontologies that is de-centralised and exploits content-based networking. We argue that this approach promises a user-centric, timely, secure and location-independent mechanism, which is potentially more scaleable and universal than existing centralised portals
The Management and Use of Social Network Sites in a Government Department
In this paper we report findings from a study of social network site use in a
UK Government department. We have investigated this from a managerial,
organisational perspective. We found at the study site that there are already
several social network technologies in use, and that these: misalign with and
problematize organisational boundaries; blur boundaries between working and
social lives; present differing opportunities for control; have different
visibilities; have overlapping functionality with each other and with other
information technologies; that they evolve and change over time; and that their
uptake is conditioned by existing infrastructure and availability. We find the
organisational complexity that social technologies are often hoped to cut
across is, in reality, something that shapes their uptake and use. We argue the
idea of a single, central social network site for supporting cooperative work
within an organisation will hit the same problems as any effort of
centralisation in organisations. We argue that while there is still plenty of
scope for design and innovation in this area, an important challenge now is in
supporting organisations in managing what can best be referred to as a social
network site 'ecosystem'.Comment: Accepted for publication in JCSCW (The Journal of Computer Supported
