Abstract

This paper presents a new solution for conceptually modeling the training‐domain knowledge of intelligent computerassisted instructional (ICAI) systems. Various cognitive demands from learners impose various modalities of presenting and structuring the knowledge to be taught. This paper is presenting a theoretical framework allowing to develop coherent, flexible models for the training‐domain knowledge of an ICAI system. A case study and an authoring‐system are also presented, in order to describe the main features of the modeling methods. This new approach in ICAI systems’ domain‐knowledge structuring and representation can offer a solution to the problem of adapting the instructional system interaction to users with different learning styles and needs.

Abstract

A formalism for representing descriptions based upon labelled directed graphs is presented. Node and edge labels are assumed to lie in lattice‐like structures which capture certain semantic relationships between object classes and predicates, respectively. With this as a framework, the problem of inferring descriptions of a concept from examples is defined. In particular, the problem of constructing a more general description can be viewed as a process of iverting transformations used to generate instances of a description. Several examples are given and some problems are cited.

Abstract

An information system is the result of a hierarchy of decisions—Who are the system users? What are their information needs? What formal services will be offered to them? Through what media will services be provided? How will these media be produced? At every point there are alternative answers to these questions.

Abstract

This paper discusses how project management styles and methods impact on energy conscious design decisions by building design teams. Within the broad field of energy conscious design the emphasis of this paper is on the selection of energy saving technologies in appropriately configured building components. The premise of the research is that these selections are not well rationalized. Choices of energy saving features in current practice are discussed against the background of available computational tools and the way these tools are used (or not) to enhance the decision‐making process. Through empirical data gathering based on case studies, improved project management techniques that enable a more timely and rational selection of energy saving technologies will be identified. A follow‐up research project that implements the findings in an operational design system is briefly presented to sketch the practical implications of the reported research.

Abstract

Purpose

The purpose of this paper is to investigate the batch treatment of pulp and paper mill wastewater using electro-coagulation (EC).

Design/methodology/approach

Statistical experimental design was used to investigate the effect of initial pH, current density and temperature. Experiments were planned to obtain the maximum amount of information in the fewest number of runs. Minimum-maximum values of current density, initial pH, temperature of medium were selected as 9-25 mA/cm2, 5-9, 25-50°C, respectively. A total number of 20 experiments including eight factorial points, six axial points and six replicates in centre points were carried out and experimental data were collected. Optimum operating parameters were determined by evaluating experimental results in MATLAB 7.9®.

Findings

According to the results, the optimum values of current density, initial pH and temperature of medium are determined as 14.12 mA/cm2, 8.22 and 34.21°C, respectively.

Practical implications

Many researches about different techniques including physical, chemical and biological methods have been done on the subject of pulp and paper wastewater treatment. In physical and chemical processes low molecular weight compounds are not removed efficiently, also these methods are quite expensive. Electrochemical degradation has an advantage of removing even the smallest colloidal particles compared with traditional flocculation and coagulation.

Originality/value

Complete removal of pollutants, less sludge generation, simple process design and easy operation are standard features of the EC and it comes forward as one of the promising techniques.

Abstract

Cognition and psychology have become central issues in economics. While this interest represents a radical change in economic theory, it does have a useful history that we believe is only partially recognized by contemporary economists. Although it is customary to cite Herbert Simon's important work in this regard,1 we suggest Hayek's earlier work The Sensory Order (1952) should enjoy similar billing.

Abstract

Purpose

The purpose of this paper is to provide insights on the relational dimension of a networked business incubator (NBI), by investigating the intermediary role of incubator management in fostering social and business ties linking tenants among each other, with the incubator management and external actors.

Design/methodology/approach

The paper offers a literature review on the NBIs and advances a comprehensive analytical framework of the networked incubation model. This framework is empirically illustrated through a case study research on a leading Italian private NBI, namely, H-Farm. The collection of primary data was conducted by means of face-to-face in-depth interviews and a survey. Data were processed through social network analysis (SNA) tools.

Findings

The results highlight the co-presence and interaction of social and business ties, which build up a vital environment nurturing an entrepreneurial ecosystem. Community-based relationships and the intermediation of incubator management are crucial for supporting tenants in product and business development activities.

Research limitations/implications

These results pave the way to further research, oriented to the conceptualization of a NBI as a (small) cluster. Moreover, the application of the SNA tools adopted invites further research on networked incubators, applying the same methodology in new directions.

Originality/value

This paper adds to previous literature on NBIs by providing evidence of the intermediary role of incubator management in promoting and facilitating social and business relationships occurring among tenants, between tenants and the incubator management, as well as with external advisors, clients and suppliers.
