Editor's introduction to the forum on defining applied communication scholarship

Although public meetings are a frequent method of public participation and risk communication, little research investigates what citizens think about their use in environmental management. To examine satisfaction with public meetings, residents of two neighboring communities received questionnaires following a public meeting about a local landfill. Respondents included residents who did and did not attend the meeting. Irrespective of whether respondents had ever attended a public meeting, meeting expectations and perceptions of relational/informational communication at meetings, including whether respondents thought meeting organizers were genuinely interested in participants' comments or meetings were informative, predicted satisfaction. Perceived risk associated with the recent meeting's topic and credibility of government agencies that frequently conduct meetings also predicted satisfaction.     

我国广告代理制发展的历程审视

Poser,an Online Review Tool in Java

This paper presents an online reviewing tool, Poser, written in the Java programming language. Online quizzing tools have proliferated lately, but most are not so well-suited for reviewing. Poser's basic functionality is to provide students with a convenient, interactive way to review course materials in a question/answer format. Incorrect responses are corrected, along with an optional explanation. The program keeps usage statistics and information on responses to questions. Poser can be an important part of any course, because it gives students an easy way to test their understanding of the course materials from any Internet computer. We used Poser in two introductory Computer Science courses and gathered some formative data which was used to modify and evaluate the program. Over 100 students used the program and they answered over 38,000 questions while reviewing for their final exams. Student comments indicate that the program was very helpful. Overall, we feel that Po ser was a huge success and are planning a controlled study in the coming semesters to measure how much the use of the program facilitates student learning and understanding.     

Change in throwing pattern: critical values for control parameter of velocity

The purpose of this study was to determine the critical values at which throwing patterns change when scaling up on the control parameter of velocity. Thirty-six participants (ages: 6-12 years) were categorized into four throwing levels according to patterns represented by temporal joint lag. Each participant was required to complete 5 overhand throws at each of 10 relative velocities for a total of 50 trials per participant. The lowest velocity was 10% of maximum, with increases in increments of 10% up to a maximum effort. Quantitative and qualitative analyses indicated that critical values varied according to throwing category and joint. Generally, lower skilled throwers (Levels 1 and 2) had less stable joint lag and changed patterns at lower velocities than higher skilled (Levels 3 and 4) throwers.
