This paper applies the construct of task uncertainty to study relationships between product development project characteristics and project outcomes. We characterize product development projects in terms of their technology novelty and project complexity levels. This characterization is based on product development literature and organizational information processing theory. We hypothesize that...

Similar to many energy projects, the evaluation of investments in natural gas projects is influenced by technical and economic uncertainties. These uncertainties include resource characteristics, production, decline laws, prices, taxes, benchmark yield, so on. In China, conventional still dominant source. The investors are mainly large state-owned companies. Therefore, it necessary uncertaintie...

Objectives: The Percentage of vowel correct (PVC) is one of the indices in the development of articulation and phonological skills in children that can be measured with speech samples that could be extracted from the single word or connected speech tests. The aim of this study is to introduce the PVC scale in Persian speaking children and investigate its validity and reliability. Methods: Th...

To address major threats to the sustainability and quality of life in urban settings, many municipalities have started exploring routes toward smarter cities to, for example, lower their energy consumption carbon footprint. These explorations, form living labs or other pilot projects, often suffer from problems scaling up initial try-outs. In this study, we identify mechanisms that facilitate d...

There is a wealth of literature about the incorporation of clients with real business problems in software engineering courses. There is, however, little by the way of direction in the selection of projects. In this paper we analyse six years of experiences of teaching software engineeering using a client based approach. We develop guidelines to aid in the identification of clients and projects...

To address the speeding problem in residential areas, the City of Edmonton initiated a pilot project to reduce the posted speed limit from 50km/h to 40km/h within six residential communities. This paper investigates the community perceptions of traffic safety within the six pilot communities in two phases: prior to project initiation (pre-pilot) and following the end of the project (post-pilot)...

This is an exciting time to be a biologist. The advances in our field and the many opportunities to expand our horizons through interaction with other disciplines are intellectually stimulating. This is as true for people tasked with helping the field move forward through support of research and education projects that serve the nation's needs as for those carrying out that research and educati...

Who would you choose to write a book about the history of the Math Wars, a topic surely familiar by now to almost all readers of the Notices (if not, see [1])? A mathematics educator? Probably not, since most such are biased toward the progressive school of mathematics education. A mathematician? Again, probably not, since most of them are avid exponents of the traditional view of mathematics e...
