The implementation and use of new information technology initiate changes. These changes can be either of a technological nature (and often explicitly known), or of a social nature (usually not as easily identifiable). Nonetheless, both the technological and social factors should be managed. When faced with change, managers should follow an appropriate change strategy. As all changes are not al...

To improve demand chain performance, is it better for parties in a supply chain to focus first on lead time reduction, or instead concentrate on improving the transfer of demand information upstream in the chain? Even though the theory of supply and demand chain management suggests that lead time reduction is an antecedent to the use of market mediation (i.e., adjusting production to fit actual...

The main challenge of the post-genomic era is to functionally characterize genes identified by the genome sequencing projects. Model organisms, including zebrafish, are indispensable for this demanding task. Zebrafish has been successfully incorporated into large-scale genetic screens due to the optical clarity of the embryos and their accessibility to various experimental techniques throughout...

In this paper, we extend the notions of γ-operation introduced in [12], by using the soft ideal notions. We introduce the notions of Ĩ-open soft sets, pre-Ĩopen soft sets, α-Ĩ-open soft sets, semi-Ĩ-open soft sets and β-Ĩ-open soft sets to soft topological spaces. We study the relations between these different types of subsets of soft topological spaces with soft ideal. We also introduce the co...

This study investigates experimentally the relationship between induced vibration and surface roughness in turning of 41Cr4 Alloy steel using Response Surface Methodology RSM. The levels of process cutting parameters in the study are limited to the following data; Depth of cut (1.0, 2.0, 3.0 mm), cutting speed (260, 320, 400 rpm), feed rate (0.15, 0.20, 0.30 mm/rev), tool nose radius (0, 1, 2 m...

Investments in information technology (IT) do not always result in the expected payoffs. The factors which determine the success of IT investments are not well understood. Event studies are one approach to appraising IT investments. In this paper we review major event studies on IT investments, and based on the results of these studies, we propose a conceptual model describing the factors that ...

Tobacco documents research has developed into a thriving academic enterprise since its inception in 1995. The technology supporting tobacco documents archiving, searching and retrieval has improved greatly since that time, and consequently tobacco documents researchers have considerably more access to resources than was the case when researchers had to travel to physical archives and/or electro...

This report is an overview on co-design in an instructional context with intergenerational teams of adults and children aged 7–11 year old. Adults and children become design partners in the design development process of new technology. I will start by introducing the main ideas of co-design. Then I will focus on the user research methods used in co-design sessions. For describing them concretel...
