Centralized vs. decentralized computing : organizational considerations and management options
The long-standing debate over whether to centralize or decentralize computing is examined in terms of the fundamental organizational and economic factors at stake. The traditional debate is examined and found to focus predominantly on issues of efficiency vs. effectiveness, with solutions based on a rationalistic strategy of optimizing in this tradeoff. A more behavioralistic assessment suggests that the driving issues in the debate are the politics of organization and resources, centering on the issue of control. The economics of computing deployment decisions is presented as an important issue, but one that often serves as a field of argument that is based on more political concerns. The current situation facing managers of computing, given the advent of small and comparatively inexpensive computers, is examined in detail, and a set of management options for dealing with this persistent issue is presented
PABED A Tool for Big Education Data Analysis
Cloud computing and big data have risen to become the most popular
technologies of the modern world. Apparently, the reason behind their immense
popularity is their wide range of applicability as far as the areas of interest
are concerned. Education and research remain one of the most obvious and
befitting application areas. This research paper introduces a big data
analytics tool, PABED Project Analyzing Big Education Data, for the education
sector that makes use of cloud-based technologies. This tool is implemented
using Google BigQuery and R programming language and allows comparison of
undergraduate enrollment data for different academic years. Although, there are
many proposed applications of big data in education, there is a lack of tools
that can actualize the concept into practice. PABED is an effort in this
direction. The implementation and testing details of the project have been
described in this paper. This tool validates the use of cloud computing and big
data technologies in education and shall head start development of more
sophisticated educational intelligence tools
The Utilization of Mobile Technology for Crime Scene Investigation in the San Francisco Bay Area
The research presented aims to explore factors affecting the decision to adopt a mobile crime scene investigation application in police departments throughout the San Francisco Bay Area. To accomplish this goal, the mobile technology acceptance model was used in designing a survey for data collection. This model utilizes four categories to interpret the factors that influence a police officer’s decision to accept or reject mobile technologies: performance, security and reliability, management style, and cognitive acceptance. Nine police departments were sampled through a series of in-person and over-the-phone interviews to obtain data regarding factors affecting the adoption of a mobile crime scene investigation application. Results suggest that if a mobile crime scene investigation application were made available, a vast majority of the police departments in the Bay Area would implement this new technology
Interoperability, Trust Based Information Sharing Protocol and Security: Digital Government Key Issues
Improved interoperability between public and private organizations is of key
significance to make digital government newest triumphant. Digital Government
interoperability, information sharing protocol and security are measured the
key issue for achieving a refined stage of digital government. Flawless
interoperability is essential to share the information between diverse and
merely dispersed organisations in several network environments by using
computer based tools. Digital government must ensure security for its
information systems, including computers and networks for providing better
service to the citizens. Governments around the world are increasingly
revolving to information sharing and integration for solving problems in
programs and policy areas. Evils of global worry such as syndrome discovery and
manage, terror campaign, immigration and border control, prohibited drug
trafficking, and more demand information sharing, harmonization and cooperation
amid government agencies within a country and across national borders. A number
of daunting challenges survive to the progress of an efficient information
sharing protocol. A secure and trusted information-sharing protocol is required
to enable users to interact and share information easily and perfectly across
many diverse networks and databases globally.Comment: 20 page
