Next Generation Teaching and Learning ??? Technologies and Trends
The landscape of teaching and learning has been radically shifted
in the last 15 years by the advent of web technologies, which
enabled the emergence of Learning Management Systems (LMS).
These systems changed the educational paradigm by extending the
classroom borders, capturing and persisting course content and
giving instructors more flexibility and access to students and other
resources. However, they also constrained and limited the
evolution of teaching and learning by imposing a traditional,
instructional framework. With the advent of Web 2.0
technologies, participation and collaboration have become
predominant experiences on the Web. The teaching and learning
community, as a whole, has been late to capitalize on these
technologies in the classroom. Part of this trend is due to
constraints in the technology (LMS), and part is due to the fact
that participatory media tools require an additional shift in
educational paradigms, from instructional, on-the-pulpit type of
teaching, to a student-centered, adaptive environment where
students can contribute to the course material and learn from one
another. This panel will discuss the next generation of teaching
and learning, involving more lightweight, modular systems to
empower instructors to be flexible, explore new student-centered
paradigms, and plug and play tools as needed. We will also
discuss how the iSchools are and should be increasingly involved
in studying these new forms, formulating best practices and
supporting the needs of teachers as they move toward more
collaborative learning environments
The Evolution of the Field of Human Resource Information Systems: Co-Evolution of Technology and HR Processes
In this paper, we review the professional and academic development of the human resource information systems (HRIS) field to assess its progress and suggest ways for moving research forward. To do so, we examine the interplay between the evolution of technology and the HR field through four key eras of technology: 1) mainframe, 2) client server, 3) ERP and Web-based systems, and 4) cloud-based systems. In each era, we discuss how HR practices and requirements drove the need for the use of these systems and how these systems allowed the HR field to evolve. In addition, we trace the HRIS subfield and its relation to the technological evolutions occurring in the HR field. Somewhat surprisingly, we found that much of the research on the use of technology to support HR has occurred only in the last 15-20 years as a response to the use of the Web as a medium for delivering HRIS. We conclude by discussing how scholars from the information systems and human resources fields can come together to help advance HRIS
Thesauri and Semantic Web: Discussion of the Evolution of Thesauri toward their Integration With the Semantic Web
15 p.Thesauri are Knowledge Organization Systems (KOS), that arise from the consensus of wide communities. They have been in use for many years and are regularly updated. Whereas in the past thesauri were designed for information professionals for indexing and searching, today there is a demand for conceptual vocabularies that enable inferencing by machines. The development of the Semantic Web has brought a new opportunity for thesauri, but thesauri also face the challenge of proving that they add value to it. The evolution of thesauri toward their integration with the Semantic Web is examined. Elements and structures in the thesaurus standard, ISO 25964, and SKOS (Simple Knowledge Organization System), the Semantic Web standard for representing KOS, are reviewed and compared. Moreover, the integrity rules of thesauri are contrasted with the axioms of SKOS. How SKOS has been applied to represent some real thesauri is taken into account. Three thesauri are chosen for this aim: AGROVOC, EuroVoc and the UNESCO Thesaurus. Based on the results of this comparison and analysis, the benefits that Semantic Web technologies offer to thesauri, how thesauri can contribute to the Semantic Web, and the challenges that would help to improve their integration with the Semantic Web are discussed.S
Lo stato dellâarte dellâinnovazione tecnologica per le architetture web: presente e futuro per Archeologia e Calcolatori
The paper illustrates the recent evolution of web architectures and the choices made for the web portal of âArcheologia e Calcolatoriâ. The website needed an urgent restyling to update its ASP platform, even though for 15 years it had performed its interactive work very well. Today, the ASP language is no longer supported by Microsoft and the infrastructural choices of the CNR are and will be increasingly oriented towards the world of open source and LAMP architectures (Linux, Apache, MySQL, PHP/Phyton). For this reason, a transformation was not only suggested, but vital. It was therefore decided to completely renew the website, a task consisting of about 70 physical pages to be rewritten in PHP. This work transformation has helped to pave the way for new technologies that today are modifying the web architecture of the entire WWW and that will soon allow us to implement new services and functions. Particular attention was paid to the most significant phenomena in the innovative technological panorama of Web Information Systems, with particular emphasis on the Semantic Databases and the new RIA (Rich Internet Application) technologies, the latter a splendid evolution of client-side web architectures

On the sustainability of web systems evolution
In the last twenty years, the evolution of web systems has been driven along three dimensions: the processes used to develop, evolve, maintain and re-engineer the systems themselves; the end products (the pages, content and links) of such processes; and finally the people dimension, with the extraordinary shift in how developers and users shape, interact and maintain the code and content that they put online. This paper reviews the questions that each of these dimensions has addressed in the past, and indicates which ones will need to be addressed in the future, in order for web system evolution to be sustainable. We show that the study on websites evolution has shifted from server- to client-side, focusing on better technologies and processes, and that the users becoming creators of content open several open questions, in particular the issue of credibility of the content created and the sustainability of such resources in the long term
Evolutionary ecology in-silico: Does mathematical modelling help in understanding the "generic" trends?
Motivated by the results of recent laboratory experiments (Yoshida et al.
Nature, 424, 303-306 (2003)) as well as many earlier field observations that
evolutionary changes can take place in ecosystems over relatively short
ecological time scales, several ``unified'' mathematical models of evolutionary
ecology have been developed over the last few years with the aim of describing
the statistical properties of data related to the evolution of ecosystems.
Moreover, because of the availability of sufficiently fast computers, it has
become possible to carry out detailed computer simulations of these models. For
the sake of completeness and to put these recent developments in the proper
perspective, we begin with a brief summary of some older models of ecological
phenomena and evolutionary processes. However, the main aim of this article is
to review critically these ``unified'' models, particularly those published in
the physics literature, in simple language that makes the new theories
accessible to wider audience.Comment: 28 pages, LATEX, 4 eps figure
Managing evolution and change in web-based teaching and learning environments
The state of the art in information technology and educational technologies is evolving constantly.
Courses taught are subject to constant change from organisational and subject-specific reasons. Evolution
and change affect educators and developers of computer-based teaching and learning environments alike â
both often being unprepared to respond effectively. A large number of educational systems are designed
and developed without change and evolution in mind. We will present our approach to the design and
maintenance of these systems in rapidly evolving environments and illustrate the consequences of evolution
and change for these systems and for the educators and developers responsible for their implementation and
deployment. We discuss various factors of change, illustrated by a Web-based virtual course, with the
objective of raising an awareness of this issue of evolution and change in computer-supported teaching and
learning environments. This discussion leads towards the establishment of a development and management
framework for teaching and learning systems

Classification of information systems research revisited: A keyword analysis approach
A number of studies have previously been conducted on keyword analysis in order to provide a comprehensive scheme to classify information systems (IS) research. However, these studies appeared prior to 1994, and IS research has clearly developed substantially since then with the emergence of areas such as electronic commerce, electronic government, electronic health and numerous others. Furthermore, the majority of European IS outlets - such as the European Journal of Information Systems and Information Systems Journal - were founded in the early 1990s, and keywords from these journals were not included in any previous work. Given that a number of studies have raised the issue of differences in European and North American IS research topics and approaches, it is arguable that any such analysis must consider sources from both locations to provide a representative and balanced view of IS classification. Moreover, it has also been argued that there is a need for further work in order to create a comprehensive keyword classification scheme reflecting the current state of the art. Consequently, the aim of this paper is to present the results of a keyword analysis utilizing keywords appearing in major peer-reviewed IS publications after the year 1990 through to 2007. This aim is realized by means of the two following objectives: (1) collect all keywords appearing in 24 peer reviewed IS journals after 1990; and (2) identify keywords not included in the previous IS keyword classification scheme. This paper also describes further research required in order to place new keywords in appropriate IS research categories. The paper makes an incremental contribution toward a contemporary means of classifying IS research. This work is important and useful for researchers in understanding the area and evolution of the IS field and also has implications for improving information search and retrieval activities
Matching demand and offer in on-line provision: A longitudinal study of monster.com
This is the post-print version of the final published paper that is available from the link below.When considering the jobs market, changes or recurring trends for skilled employees expressed by employers' needs have a tremendous impact on the evolution of website content. On-line jobs sites adverts, academic institutions and professional development âstandard bodiesâ all share those needs as their common driver for contents evolution. This paper aims, on one hand, to discuss and to analyse how current needs and requirements (âdemandâ) of IT skills in the UK job market drive the contents of different types of websites, in turn analysing whether this demand changes and how. On the other hand, it is studied what the UK higher education institutions have to offer to fulfill this demand. The results found analysing the evolution of the largest on-line job centre (www.monster.com), and the websites of selected UK academic institutions, demonstrate that often what is requested by UK industries is not clearly offered by UK institutions. Given the prominence of monster.com in the global economy, these results could provide a meaningful starting point to support curricula development in UK, as much as worldwide
