A comparative study across the most widely known blockchain technologies is conducted with a bottom-up approach. Blockchains are disentangled into building blocks. Each building block is then hierarchically classified in main and subcomponents. Then, alternative values (i.e., layouts) for the subcomponents are identified and compared between them. Finally, an ontology matrix summarises the stud...

The hypothesis that theories might influence observation was proposed in the important early work of Hanson (1958) and Kuhn (1962). It has been brought to a new focus by the interchanges between Fodor (1984, 1988) and Churchland (1979, 1988). Fodor has argued that perception is not cognitively penetrable, while Churchland has argued for a strong form of theory-Iadenness. This issue has led to v...

The paper considers the potential offered by lifelong learning as a tool for capacity building and development in rural areas, especially through the exploitation of contemporary technologies. The challenges and opportunities connected with small rural schools are particularly focused upon, and teachers working in them are proposed as ideal change agents potentially powerful to catalyse bottom-...

Hierarchies provide scalability in large networks and are integral to many widely-used protocols and applications. Previous approaches to constructing hierarchies have typically either assumed static hierarchy configuration, or have used bottom-up construction methods. We describe how to construct hierarchies in a top-down fashion, and show that our method is much more efficient than bottom-up ...

A novel inattention search paradigm (Mack & Rock, 1998) was used to assess the visual efficiency of fluorescent colored relative to nonfluorescent colored highway signs in a laboratory setting. Unexpected presentation of a fluorescent colored search target was not accompanied by an improvement in visual search time. However, visual search times improved dramatically once the participants develo...

Product lines evolve out of existing products. In order to evaluate the potential of creating a product line from existing products it is necessary to ‘mine’ their architectures and analyze the commonalities and variabilities across those architectures. To manage the evaluation process in a disciplined way this paper introduces the MAP (Mining Architectures for Product lines) method. MAP outlin...

Culture is assumed to play a pivotal role in business success and failure. In contrast to prevailing top-down perspectives, we propose an approach to studying culture that accounts for myriad organizational subcultures, how individuals fit into those subcultures, and the causes and consequences of shifts in culture and cultural fit. We propose that the language through which people communicate ...
