A Case Studies Approach to the Analysis of Profiling and Framing
Structures for Pervasive Information Systems

Model-Based/Driven Development (MDD) constitutes an approach to software
design and development that potentially contributes to: concepts closer
to domain and reduction of semantic gaps, automation and less
sensitivity to technological changes, and the capture of expert
knowledge and reuse. The widespread adoption of pervasive technologies
as basis for new systems and applications lead to the need of
effectively design pervasive information systems that properly fulfil
the goals they were designed for. This paper presents a profiling and
framing structure approach for the development of Pervasive Information
Systems (PIS). This profiling and framing structure allows the
organization of the functionality that can be assigned to computational
devices in a system and of the corresponding development structures and
models, being. The proposed approach enables a structural approach to
PIS development. The paper also presents two case studies that allowed
demonstrating the applicability of the approach.

Today’s manufacturing enterprises face enormous competitive pressures
stemming from the current dynamic and open business context. Global
competition and market demand for customized products and services,
delivered ‘just in time’, exert real stress on businesses. Recently, new
production paradigms, such as the extended enterprise, as well as agile,
virtual and networked manufacturing, have appeared in response to the
increasingly dynamic conditions of the marketplace. These new concepts
prompt geographically dispersed manufacturers to build alliances with
their suppliers and customers in order to work more closely with them.
They need to work to build manufacturing networks which bridge large
sections of the supply chain. In this context distributed scheduling
problems are challenging tasks to researchers and practitioners that
have been gaining increasing popularity over the years. This is partly
attributed to the fact that multi-site production and networked
manufacturing environments are increasing as a consequence of
globalization. In this paper a web based system for technologies
integration for supporting distributed scheduling in a Virtual
Enterprise, by combining a simulation-based approach, with the Hungarian
algorithm, for solving job-shop scheduling problems is presented, in
order to show how the authors can benefit from this technologies
integration for supporting collaborative distributed manufacturing
scheduling.

Business Organizations increasingly rely on publicly accessible
communication infrastructures such as the Internet and Cloud computing,
in order to manage their internal processes and offer their services to
financial actors, businesses and ordinary people worldwide. However,
little attention has been paid to embracing Software-as-a-Service (SaaS)
philosophy for supporting business analysts in evaluating effectiveness
and relevance of business information or finding patterns to direct them
on more sources of data. This paper proposes a flexible architectural
framework for modelling application services useful in supporting
business decision processes. This architecture goes beyond the static
schemas offered by data warehouse systems as it supports including data
gathered from heterogeneous sources and added-value services offered in
Internet or provided by Cloud infrastructures. Central to this
architecture is the concept of dataspace as a reference model for
structuring information relevant to a particular organization,
regardless of its format and location. A case study of a real world
implementation is presented dealing with supporting decisions in the
real estate domain.

*UNDERGRADUATE STUDENTS’ SATISFACTION WITH THE USE OF WEB PORTALS*

and Information Science, University of Ilorin, Nigeria)*
This study examined undergraduate students’ satisfaction with web
portals and considers the benefits of using the portal and the problems
associated with the use of portal. A pure quantitative method using
descriptive survey approach is adopted. A questionnaire was used for
data collection. Collected data was analysed using percentages and
frequency count; multiple correlation and regression. The results reveal
that students were generally satisfied with the e-portal system with,
89.3% indicating they were adequately satisfied, satisfied, and
moderately satisfied. On the other hand, 11.1% had little satisfaction
with the portal. Information/content quality, system quality, and ease
of use were indicated to determine users’ satisfaction. Furthermore, the
entire user satisfaction dimensions positively and significantly
correlate with and predict students’ satisfaction with the web-portal.
The study concluded by pointing out the implications and the
recommendations based on the findings for the improvement of the
students’ web portal.

*Script Familiarity and Its Effect on CAPTCHA Usability: An Experiment
with Arab Participants*

University, UAE), Salam Abdallah (College of Business Administration,

Many web-based services such as email, search engines, and polling sites
are being abused by spammers via computer programs known as bots. This
problem has bred a new research area called Human Interactive Proofs
(HIP) and a testing device called CAPTCHA, which aims to protect
services from malevolent attacks by distinguishing bots from human
users. In the past decade, researchers have focused on developing robust
and safe HIP systems but have barely evaluated their usability. To begin
to fill this gap, the authors report the results of a user study
conducted to determine the extent that English language proficiency
affects CAPTCHA usability for users whose native language is not
English. The results showed a significant effect of participants’
English language proficiency level on the time the participant takes to
solve CAPTCHA, which appear to be related to multiple usability issues
including satisfaction and efficiency. Yet, they found that English
language proficiency level does not affect the number of errors made
while entering CAPTCHA or reCAPTCHA. The authors’ results have numerous
implications that may inform future CAPTCHA design.

*CALL FOR PAPERS*
Mission of IJWP:
The *International Journal of Web Portals (IJWP)* focuses on enterprise
integration strategy that deals with the exchange of messages as the
basic component of the solution architecture enabling the integration of
people, information, applications and business processes. Portals are
expected to care more about the infrastructure services they consume,
which is a key architectural difference between the past and the future
generations of portals and represent the paradigm shift in enterprise
integration strategy. This paradigm shift focuses on identifying core
integration components, assets, enterprise portals and encourages the
reuse and refinement of these assets for integration projects. However,
these topics are rarely discussed among the practitioners or in the
international journals without primarily encouraging use of the
solutions from particular vendors. It is important to establish a
sounding board (international journal) which provides readers with an
independent view of models for enterprise integration strategies, vendor
independent tool sets, and the experience with the development of
strategic solutions carried out within the context and rules of the
enterprise's integration architecture. The readers are expected to
benefit from having access to the latest practical solutions, as well as
research papers in the field of integration approaches, the review of
tools which can effectively and proactively support integration
objectives across the enterprise.
Coverage of IJWP:
Topics to be discussed in this journal include, but are not limited to,
the following:
Business process integration and management using SOA and portals
Case studies for using portals with content management systems
Composite Web service in portal frameworks (creation and enabling
infrastructure)

E-commerce applications based on portals and SOA
Evolution of B2E & B2B portals as windows into the enterprise, on demand
services in portals
Frameworks for building portal applications, development tooling, and
development environments (e.g Portlet Factory, NetBean portal plug-in,
and other tools)
Frameworks for designing SOA solution with portal platforms, models, and
modeling tools usage, efficiency, and usability
Grid portals
Managing development of portals & SOA solutions
Mobile portals, mobile portal platform, and content management systems
applied to mobile portals
Portal architecture, research, and practical issues in portals,
including mobile portal initiatives
Portal security issues and single sigh-on
