Many workers on the subject of pteroylglutamic-acid (PGA) deficiency in the rat have obtained data about the requirement of the rat for this vitamin; but so far the emphasis has been on the therapeutic dose required to correct a given deficiency rather than on the amount necessary for maintenance. Figures for the normal requirement are needed as a guide in the preparation of certain purified di...

A Conversational Agent can be useful for providing assistance to naïve users on how to use a graphical interface. Such an assistant requires three features: understanding users’ requests, reasoning, and intuitive output. In this paper we introduce the DAFT-LEA architecture for enabling assistant agents to reply to questions asked by naive users about the structure and functioning of graphical i...

Within the literature on decision-making, information and communication technologies (ICT) and associated theories such as the Information Richness Theory (Daft and Lengel, 1986), there is little focus on the urgent decision-making process, particularly the role of ICT in these situations. This study examines how members of a senior management team in the New Zealand public sector make decision...

Over the years, many theories have been used to understand e-communication and e-collaboration behavior (Kock, 2004; Markus, 2005). Arguably, the most widely used among those theories has been media richness theory (Daft & Lengel, 1986) even though there has been mounting evidence that its predictions do not hold in a number of situations (Markus, 1994). One key prediction of media richness the...

Traditional lightning protection practices were standardized many years prior to the recent proliferation of modern electrical and electronic equipment installations on building rooftops. This paper presents an isolated down-conductor solution that combines the advantages of the IEC 623051 series or various other national standards regarding isolated and non-isolated lightning protection method...

We document that firms’ management of accounting earnings increased steadily from 1987 until the passage of the Sarbanes Oxley Act (SOX), with a significant increase during the period prior to SOX, followed by a significant decline after passage of SOX. However, the increase in earnings management preceding SOX was primarily in poorly performing industries. We also show that the informativeness...
