Interactive displays are becoming an increasingly popular civic engagement mechanism for collecting user feedback in urban settings. However, to date no study has investigated (i) how the situatedness of public displays affects the quantity and quality of collected feedback, and (ii) how public displays compare to traditional paper or web feedback mechanisms. We answer these research questions ...

We report experimental evidence showing a direct correlation between the alignment of carbon nanofibers ~CNFs! prepared by plasma-enhanced chemical-vapor deposition and the location of the catalyst particle during CNF growth. In particular, we find that CNFs that have a catalyst particle at the tip ~i.e., growth proceeds from the tip! align along the electric-field lines, whereas CNFs with the ...

since the emergence of the process-oriented approach in second language writing instruction, the issues of writing instruction have been predominantly concerned with what and how error feedback should be given to the students’ writing. the present study investigated the effect of explicit corrective feedback on writing accuracy of iranian intermediate efl learners (n = 44) in hamedan islamic az...

This research chiefly focused on the application of mitigation strategies and traditional form of feedback in writing development of the fifth semester University students majoring in TEFL and English Translation fields based on Vygotsky’s sociocultural theory in general and the notion of “Zone of Proximal Development” in particular. To that end, this study relied on a pre-posttest experimental...

Annually between 1994 and 1998 over 400,000 acres of grain sorghum have been harvested in Missouri with an average yield of 86/bushels/acre. The average value of production during this period was over $90 million. Grain sorghum (milo) is an important crop for some Missouri producers. Many sorghum producers also produce corn, soybean, or wheat. Each of these commodities has an actively traded fu...
