Meta-analysis and structural equation modeling (SEM) are two important statistical methods in the behavioral, social, and medical sciences. They are generally treated as two unrelated topics in the literature. The present article proposes a model to integrate fixed-, random-, and mixed-effects meta-analyses into the SEM framework. By applying an appropriate transformation on the data, studies i...

Collective Awareness Platforms (CAP) have been promoted as an enabler of social innovation. A CAP supports the collection of data (quantitative and qualitative, and using all the technical possibilities that are rapidly becoming available, e.g. sensors), the integration of the data, and the presentation of results to the community in order to adapt their behavior or develop new behavior pattern...

This article is concerned with the question as to whether the components of grammar (syntax, semantics and phonology) have a similar architecture. I provide a modest historical background to the recurrent discussion about the parallelisms between syntax and phonology within Generative Grammar and mention some ‘meta-patterns’, i.e., shared properties of linguistic structures in different modules...

Current semantic approaches to multimedia content modeling treat the content’s media, the semantic description of the content, and the functionality performed on the content such as rendering as separate entities, usually kept on separate servers in separate files or databases and typically under the control of different authorities. This separation of content from its description and functiona...

Most performance critical software is developed using very low-level techniques. We argue that this needs to change, and that generative programming is an effective avenue to enable the use of high-level languages and programming techniques in many such circumstances. 1998 ACM Subject Classification D.1 Programming Techniques

Foundry is one of the activities that has contributed to evolve the society, however, the manufacturing process is carried out in the same manner as it was many years ago. Therefore, several defects may appear in castings when the production process is already finished. One of the most difficult defect to detect is the microshrinkage: tiny porosities that appear inside the casting. Another impo...

We have analyzed data from two online courses designed to promote collaborative online learning. Ongoing assessment (self, group, instructor) that actively engages students within the course (as opposed to instructor assessment at the end) is a central feature for achieving collaborative knowledge building in online dialog. Careful articulation and deployment of assessment criteria is a design ...

Situational Method Engineering for constructing ad-hoc agent oriented design process is grounded on a well defined set of phases that are principally based on reuse of components coming from existing agent design processes that have to be stored in a repository. The identification and extraction of these components could take large advantage from the existence of a standardized representation o...

Both coarse-to-fine and A∗ parsing use simple grammars to guide search in complex ones. We compare the two approaches in a common, agenda-based framework, demonstrating the tradeoffs and relative strengths of each method. Overall, coarse-to-fine is much faster for moderate levels of search errors, but below a certain threshold A∗ is superior. In addition, we present the first experiments on hie...

The purpose of this demo is to introduce the Language Resources, Tools and Services (LRTS) that are being prepared within the Central and South-East European Resources (CESAR) project. To the computational linguistic community the languages covered by CESAR (Bulgarian, Croatian, Hungarian, Polish, Serbian and Slovakian) were so far considered under-resourced and their language resources and too...
