Forage production of rangelands differs during different times of grazing season and in the same month of different years. In range management projects, grazing capacity calculated once during the grazing season, which coincides with the maximum production of rangeland species. This may cause more livestock entry into the rangeland during the grazing season, leading to more degradation. Th...

Software Conceptual Integrity has been considered a cardinal concern for design and development of software systems. But, except for verbal descriptions of desiderata, there were no formal tools to guarantee that conceptual integrity is attained. This paper proposes an axiomatic algebraic approach, based upon the assumption that the software system in each level of the system hierarchy is repre...

This study explored whether infants aged 12 months already recognize the communicative function of pointing gestures. Infants participated in a task requiring them to comprehend an adult's informative pointing gesture to the location of a hidden toy. They mostly succeeded in this task, which required them to infer that the adult was attempting to direct their attention to a location for a reaso...

This paper discusses Brooks’ The Mythical Man-Month, a landmark work in the software project management field, and compares the software project management advice given there with practices employed some 25 years later. To find out the state of today’s practice 20 experienced software developers were interviewed regarding their impressions of factors leading to success or failure of software de...

Computer A nalysts frequently describe troubled projects with the tar pit metaphor used so effectively in Fred Brooks’s The Mythical Man-Month (2nd ed., AddisonWesley, Reading, Mass., 1995). We have found a similarly effective metaphor: Think of a troubled software project as an insect caught in a spiderweb of sticky constraints, trying desperately to break free before the spider arrives to feed.

In Situational Method Engineering, the concepts of both fragment and chunk have been proposed as the atomic element. These are examined here in terms of their conceptual integrity and in terms of how they may be used in method construction, drawing parallels to show that the similarities are more than the differences. The new ISO/IEC 24744 standard metamodel is used as a conceptual framework to...
