this study is a typological description of written formative feedback in an efl context in iran. twenty m.a. students of tefl participated in the study. they were required to summarize a scholarly article in each session on which the instructor would provide written corrective feedback (cf). written formative comments were extracted, coded, and categorized into various types, such as asking for...

Bandwagon innovation diffusion is characterized by a positive feedback loop where adoptions by some actors increase the pressure to adopt for other actors. In particular, when gains from an innovation are difficult to quantify, such as implementing quality circles or downsizing practices, diffusion is likely to occur through a bandwagon process. In this paper we extend Abrahamson and Rosenkopf’...

Swing up and balance control are two interesting control problems for the Pendubot. Many studies have been conducted for swing up control of the Pendubot. A few results have been reported for feedback stabilization of the Pendubot. In this paper, we will apply a new hybrid controller for feedback stabilization of the Pendubot. To the best of the authors’ knowledge, this is the first implementat...

This paper studies contemporaneous relationship between S&P 500 index returns and logincrements of the market volatility index (VIX) via a nonparametric copula method. Specifically, we propose a conditional dependence index to investigate how the dependence between the two series varies across different segments of the market return distribution. We observe the following findings: (a) the two s...

The purpose of the research reported in this article was to test two hypotheses about how musicians evaluate their musical performances. The first hypothesis was that musicians’ selfevaluations would be more influenced by their expectations and their past performances than by comparisons to the performances of other musicians. The second hypothesis was that musicians would exhibit an ‘adaptive ...

We consider ranking and recommendation systems based on user feedback. We make a case for sharing the revenue generated by such systems with users as incentive to provide useful feedback. Our main contribution are mechanisms for ranking/recommendation which gives incentive for the users to provide useful feedback and is resistant to selfish/malicious behavior (click spam). The mechanisms are de...

This paper presents the stability analysis of a fuzzymodel-based control system consisting of a nonlinear plant and a nonlinear state feedback controller and the design of the nonlinear gains of the controller. The nonlinear plant is represented by a fuzzy model having rules. A nonlinear state feedback controller is designed to close the feedback loop. Under this design, the stability condition...

Our Genomics experiments mainly focus on addressing three major problems in biomedical information retrieval. The three problems are: (1) how to deal with synonyms? (2) how to deal with the frequent use of acronyms? (3) how to deal with homonyms? In particular, we propose two query expansion algorithms to construct structured queries for our experiments. The mean average precision (MAP) for our...

Recent studies have shown that introduced exotic plant species may be released from their native soilborne pathogens, but that they become exposed to increased soil pathogen activity in the new range when time since introduction increases. Other studies have shown that introduced exotic plant species become less dominant when time since introduction increases, and that plant abundance may be co...

This note analyzes incoherent feedforward loops in signal processing and control. It studies the response properties of IFFL’s to exponentially growing inputs, both for a standard version of the IFFL and for a variation in which the output variable has a positive self-feedback term. It also considers a negative feedback configuration, using such a device as a controller. It uncovers a somewhat ...
