Editors’ Introduction to This Special Issue

This issue of the Journal of Human Sciences and Extension focuses on both of these questions and provides readers with in-depth exposure to the meaning of credible and actionable evidence of program effectiveness and quality and how it can be addressed within an organization. The ten articles in this issue cover the basics of what credible and actionable evidence is; how such evidence can be identified, measured, and collected; how credible and actionable evidence can differ depending on different levels of an organization and the stakeholders wanting the evidence; how organizations can build capacity to collect credible and actionable evidence; and how this evidence can best be presented to program stakeholders

Editors\u27 Introduction to This Special Issue

This issue of the Journal of Human Sciences and Extension describes the initial work of the Task Force and then focuses on conclusions and implications from the ECOP-commissioned Health Implementation Action Teams. The purpose of this special issue is to feature the scholarship emanating from the Action Teams and to host that scholarship in one volume to showcase the depth and breadth of work accomplished by the teams. This work speaks to the future of Cooperative Extension. David Buys and Sonja Koukel served as Co-Editors for this special issue

Acquiring Procedural Knowledge of a Technology Interface: Introduction to this Special Issue.

Guidelines and models for procedural instructions can be supported by three types of research. Careful analytical studies of collections of instructions can help to identify, describe, and evaluate strategies that writers and designers apply. Empirical studies measure the effects of document variables on the performance of users, thus offering evidence, contraevidence, or refinements for existing guidelines. Theoretical studies, finally, aim to describe and explain the behavior of readers of instructions. To designers and writers, they provide a deeper insight in the underlying cognitive processes that determine success or failure of their work. This special issue offers research articles in all three categories

Nobel Prize winner and atmospheric chemist Crutzen states: During the past 3 centuries human population increased tenfold to 6,000 million, growing by a factor of four during the past century alone. More than half of all accessible fresh water is used by mankind. Fisheries remove more than 25% of the primary production of the oceans in the upwelling regions and 35% in the temperature continental shelf regions. 30–50% of the world's land surface has been transformed by human action. Coastal wetlands have lost 50% of the world's mangroves. More nitrogen is now fixed synthetically and applied as fertilizers in agriculture than fixed naturally in all terrestrial ecosystems. Many of the world's rivers have been dammed or diverted.US National Science Foundation for funding this special issue
