Using a computer-based scientific discovery learning environment on buoyancy in fluids we investigated the effects of goal specificity (nonspecific goals vs. specific goals) for two goal types (problem solving goals vs. learning goals) on strategy use and instructional efficiency. Our empirical findings close an important research gap, because in earlier studies the goal specificity effect eith...

Information quality (IQ) has become a critical concern in today’s organisations. Although recent studies of information systems indicate an increasing importance of IQ, foremost research is still limited. Indeed, little is known about the impact of various design decisions on IQ. Recent research shows that security measures are increasingly important for any information system; however security...

Sorghum (Sorghum bicolor (L.) Moench) is an economically valued food and cash crop in of Nigeria. In 2001 and 2002 cropping seasons, field experiments were conducted in a split-pot using randomized complete block design to determine the efficacy of Metalaxyl fungicide and it costbenefit on incidence of sorghum diseases in Borno State at the Teaching and Research Farm of the Department of crop p...

Over the past two decades, several studies have investigated the factors that lead to and away from individuals’ reporting of truthful status information on IT projects. These studies have typically considered the reporting decisions of an individual who is aware of negative status information that is attributed to others’ errors. These previous studies have seldom examined the situation in whi...

In this issue of JAPI there are two articles on the evaluation of suspected or known coronary artery disease : comparison of stress ECG and stress myocardial perfusion imaging (MPI), and adenosine stress MPI. This is a good opportunity to review the subject of evaluation of Coronary Artery Disease (CAD). The views expressed are based on my personal experience of 25 years in nuclear cardiology a...

In recent years, growing ecological concern has prompted for ‘design for environment’. One way to achieve this is to design products that are easy to disassemble, because this improves the ability to reuse or recycle parts of a product. This paper presents a computational theory for product modeling and reasoning about product disassembly. This theory, implemented in the PROMOD system, is based...

For more than thirty years I have been applying cost-effectiveness and costbenefit analysis to education. When I began this work in about 1970, there were almost no cost-effectiveness studies reported in the literature, and the term was not found in education at all. The term cost-effectiveness is now commonly used in justifying specific educational interventions. It has also become standard pa...

Article history: Received on: 15/05/2015 Revised on: 10/06/2015 Accepted on: 17/06/2015 Available online: 20/06/2015 Two field experiments were conducted during Kharif, 2010 and 2011 to find out economical control measures against legume pod borer, Maruca vitrata (Geyer) on pigeonpea. Experimental results showed that the per cent inflorescence damage due to Maruca was lowest in chlorantranilipr...

I'd like to leave you with just a few points. If you think back again to the opening of this conference as to why we are concerned with increased susceptibility, however one might define it, I think the panels expanded upon Dr. Barth's opening remarks. The sponsoring agency has expressed its concern that the legal mandates under which the federal agencies are working require that high risk grou...
