it Programs in high schools:
Lessons from the cisco
networking academy Program
Alan R. Dennis, Thomas M. Duffy,
and Hasan Cakir
The authors studied 5,392 students
taking a course from the Cisco
networking Academy at 764 high schools
across the U.S. to understand the factors
that influenced their achievement
and confidence. Surprisingly, school
characteristics (inner city vs. suburban,
rich vs. poor) had virtually no impact.
What mattered most was instruction
quality and an individual student‘s
ability, motivation, and, unfortunately,
gender. This style of program, with a
strong centralized curriculum, local
customization, standards-based testing,
and strong teacher support overcame the
traditional educational barriers to enable
each student to rise to his or her own level
of ability and motivation.
creating the experience
economy in e-commerce
Wei-Lun Chang, Soe-Tsyr Yuan,
and Carol W. Hsu
The potential economic value of
experience-oriented offerings has been
demonstrated in the physical marketplace.
This study suggests the widespread use
of the Internet allows the experience
economy to be extended to the virtual
marketplace. The growing practice of
online collaborative design demonstrates
the potential for providing the experience
economy via the Internet. The authors
propose expanding the existing practices
by incorporating the concept of
collaborative pricing into the design of
experience offerings, as demonstrated
in their iCare platform. The article is
intended to motivate further research
into the development of the experience
economy in e-commerce.
how Distributed Data mining tasks
can thrive as Knowledge services
Domenico Talia and Paolo Trunifo
Through a service-oriented approach
we can support distributed business
intelligence tasks in clouds and grids.
Those services can implement all the tasks
in data mining and in knowledge discovery
processes such as data selection, data
analysis, and knowledge representation.
The authors explore architectures and
services for distributed knowledge
discovery such as the Knowledge Grid, the
Weka4WS toolkit, and mobile data mining
services. The article describes a strategy
and a model based on the use of services
for the design of distributed knowledge
discovery applications and discusses
how grid and cloud frameworks can be
developed as a collection of services and
how they can be used to support knowledge
discovery processes using the SOA model.
eRP: Drilling for Profit
in the oil and Gas industry
Jorge A. Romero, Nirup Menon,
Rajiv D. Banker, and Mark Anderson
The article presents research that applies
to a new approach toward understanding
ERP implementation. Rather than looking
at ordinary measures of firm performance,
the authors examine strategic performance
measures that can only be utilized if one
delves into data that is not found on the
financial statements. It is one of the first
studies to show the sources of profitability
after an ERP implementation and will
help managers understand the strategic
and managerial implications of ERP
implementation.
Why Do People tag?
motivations for Photo tagging
Oded Nov and Chen Ye
Given the growing popularity of tags
as a means of sharing and organizing
large amounts of data, it is critical for
developers and managers of collaborative
content-sharing systems such as Flickr,
You Tube, and del.icio.us to understand
what motivates users to tag. The authors
examine individual-level motivations
using a newly developed scale as well as
the social presence driver and the number
of user photos. The findings suggest that
both social presence and individual-level
motivation affect users’ tagging level.
using esi Discovery teams to
manage electronic Data Discovery
John C. Ruhnka and John W. Bagby
Many organizations face litigation threats
with associated crippling costs, staff-time
demands, and adverse financial impacts.
“Discovery,” the legal and operational
process governing the evidentiary use of
electronically stored information (ESI)—
including email messages—plays a central
role in the cost of litigation as well as in
potential outcomes. Multidiscipline ESI
“discovery teams” containing key IT, legal,
and operational players involved in this
complex process can more effectively
manage the “litigation hold” process,
and can better assess the potential costs
of alternative strategies in collection,
identification, verification, recovery, and
production of relevant electronic data
sought as evidence.
application service Providers:
market and adoption Decisions
Yurong Yao, Edward Watson,
and Beverly K. Kahn
Deciding whether, how, and with whom to
outsource an organization’s applications
is important. Key factors influence
the Application Service Provider (ASP)
decision-making process and the ultimate
organizational success. The authors
examine the current ASP market and
recommend evaluation criteria by looking
at hosting by “Pure ASPs” (small companies
who purely provide hosting services) and
“ISVs” (independent software vendors,
who develop software and host their own
applications). These ASPs provide either
vertical (within a single industry sector) or
horizontal (across industries) applications.
Several adoption cases are presented to
explain the recommendations.
