Modeling Static Aspects of Mobile Electronic Commerce Environments

2011

Mobile phones and other small and powerful portable devices have revolutionized personal communication and affected the lifestyles of the people in the industrialized world. Following credible estimates, in a few years there will be one billion of such portable devices. An emerging trend is the electronic commerce performed using mobile terminals, often called mobile commerce. Mobile commerce environments are characterized by high complexity, including myriads of technical and organizational aspects. This property makes it difficult to distinguish the more fundamental issues, structures, and concepts in mobile commerce from the hype. To capture the fundamental aspects of mobile commerce env…

Reports and other PDF Documents

2014

Stata users often need to combine text, tables, and figures. The author's command, lpdf, generates reports and other PDF documents. lpdf compiles text stored in global macros, tables stored as dataset tables or LATEX table input files, and figures stored as Stata graphs or PDF figure files. LATEX must be installed, but familiarity with LATEX is not necessary. lpdf performs every step through Stata and with Stata syntax. It generates documents in report or article style and portrait or landscape orientation. The default author name, document title, and date can be modified. Further format options include the font and margin sizes. For each table and figure, the width and layout can be adapt…

A Public Barrier Tracker to Support the Web Accessibility Directive

2018

In this paper we propose the Public Barrier Tracker (PBT) – a comprehensive solution that supports both filing and handling of user feedback on web accessibility. We give an overview of some existing approaches for gathering user feedback on accessibility barriers and outline the PBT functionality. The PBT can also offer further support for the implementation of the WAD: The collected data could be useful for monitoring and reporting as well as the enforcement mechanism.

Towards Introducing User Preferences in OLAP Reporting Tool

2012

This paper presents an OLAP reporting tool and an approach for determining and processing user OLAP preferences, which are useful for generating recommendations on potentially interesting reports. We discuss the metadata layers of the reporting tool including our proposed OLAP preferences metamodel, which supports various scenarios of formulating preferences of two different types: schema-specific and report-specific. The process of semantic metadata usage at the stage of formulating user preferences is also considered. The methods for processing schema-specific and report-specific OLAP preferences are outlined.

OpenScout

2013

Already existing open educational resources in the field of Business and Management have a high potential for enterprises to address the increasing training needs of their employees. However, it is difficult to act on OERs as some data is hidden. In the meanwhile, numerous repositories provide Linked Open Data on this field. Though, users have to search a number of repositories with heterogeneous interfaces in order to retrieve the desired content. In this paper, we present the strategies to gather heterogeneous learning objects from the Web of Data, and we provide an overview of the benefits of the OpenScout platform. Despite the fact that not all data repositories strictly follow Linked D…

Content Production Strategies for E-Government

2008

The terms electronic government (e-government) and digital government are used to refer to the utilization of the Internet and other information and communication technologies (ICT) effectively in public sectors. In e-government development activities, the concern is often in building new means to support and strengthen democracy (e.g., Watson, Alselsen, Evjemo, & Aarsæther, 1999). In other cases, the main concern may be in supporting the work of people in public sectors (e.g., Mustajärvi, 2003), or in building new kinds of services for citizens (e.g., Lyytikäinen, Tiitinen, & Salminen, 2000). Common to most development activities is the need to have the content of public sector inf…

Location-based media sharing in a MP2P network

2008

In both academia and industry, peer-to-peer (p2p) applications have attracted great attention. This paper introduces and implemented a novel location-based multimedia application, the Multimedia Traveling Journal application (PhotoJournal) that employs the p2p paradigm and enables location-based content sharing among mobile users.

User requirements and resource control for cooperative multimedia applications

1997

The spread of distributed multimedia applications is setting forth a new set of challenges in the management of host and network resources for guaranteeing Quality of Service (QoS). When the multimedia applications compete for resources as in the case of a cooperative multimedia environment, the management task becomes even more difficult. In this work, we first discuss QoS for multimedia applications. We then present the architectural and implementation details of a Cooperative Multimedia Environment (CME) made up of Cooperative Multimedia Applications (COMMA), one for each user. A COMMA presents a user with a single interface that allows him to invite other users to a cooperative session,…

Developing web-based learning resources in school education: a user-centered approach

2010

Published version of an article from the journal:Interdisciplinary Journal of Knowledge and Learning Objects. Also available from the publisher:http://www.ijello.org/Volume6/IJELLOv6p115-135Hadjerrouit688.pdf Web-based learning resources (WBLRs) are potentially powerful tools for enhancing teachingand learning processes in school education. They can provide teachers and learners with a widerange of new and exciting experiences that are not possible in a traditional classroom. However,WBLRs are still the domain of technical and software experts rather than teachers and learners.As a result, much of the development of WBLRs is carried out without a true understanding ofissues pertinent to lea…
