Introduction to Special Issue on Hydrologic and Geomorphic Effects of Forest Roads
Roads have been a part of human landscapes for more than 40 centuries. During the 20th century, technological advances have increased our ability to construct new roads at unprecedented rates and into steeper terrain. In the last half of that century, an extensive network of roads has been constructed in forests and other wildlands to facilitate use and management of natural resources. They are...

متن کاملIntroduction to Special Issue
Although recent frameworks for test validation have emphasized utilization as a key component (e.g. Bachman & Palmer, 2010; Chapelle, 2012; Kane, 1992), what happens in the sometimes messy contexts where assessments are carried out is often not documented. This is perhaps because test developers are more focused on defining and operationalizing test constructs than on issues of implementation. ...
متن کاملIntroduction to special issue on RNA.
In this introduction to the special issue on RNA, we provide a brief overview of some of the novel and exciting biological discoveries concerning diverse roles played by RNA, and subsequently we give a rapid summary of some algorithmic aspects of RNA structure and alignment. Each of the contributions to this special issue is briefly described.
متن کاملIntroduction to the Special Issue on Summarization
As the amount of online information increases, systems that can automatically summarize one or more documents become increasingly desirable. Recent research has investigated types of summaries, methods to create them, and methods to evaluate them. Several evaluation competitions (in the style of NIST’s TREC1) have helped determine baseline performance levels and provide a limited set of trainin...
