Radio is migrating to digital transmission, expanding its offerings to include captioning for individuals with hearing loss. Text display radio requires a large amount of word throughput with minimal screen display area, making good user interface design crucial to its success. In two experiments, we presented hearing, hard-of-hearing, and deaf consumers with National Public Radio stories converted to text and examined their preferences for and reactions to midsized and small radio text displays. We focused on physical display attributes such as text color, font style, line length, and scrolling type as well as emergency alert messages and emergency prompts for drivers, announcer identification schemes, and synchronization of audio and text. Results suggest that midsized, Global Positioning System (GPS)-style displays were well liked, synchronization of audio and text was important to comprehension and retrieval of story details, identification of announcers was served best with a combination of name change in parenthesis and color change, and a mixture of color and flashing symbols was preferred for emergency alerting. 相似文献

OBJECTIVE: The purpose of this article is to describe pelvic fractures in two abused male infants, and to determine if the literature describes pelvic fractures in infants as suspicious for child physical abuse. RESULTS: Two infants are described with unexplained pelvic fractures. While in one case child abuse was obvious, careful attention to the radiological evaluation and case history led to the correct diagnosis of child abuse in the second case. A search for information regarding pelvic fractures in children resulted in information limited to the radiological and surgical literature. CONCLUSIONS: Medical providers frequently encounter children with fractures suspicious for child abuse. The most common fractures seen in abused children are metaphyseal, rib, skull, and long bone fractures. This report illustrates that pelvic fractures occurring in the absence of serious, well documented accidents should be considered highly suspicious for child physical abuse. 相似文献

The purpose of this study was to explore the negative thinking patterns of incoming community college freshmen who were undecided about choosing a major and to suggest an approach for addressing these issues on a community college campus. Sixty community college freshmen attending their freshman orientation (FO) were surveyed using the Career Thoughts Inventory (CTI). Results indicated that the students who participated in the study scored higher on all CTI scales than high school or college students in the normative sample. There were no differences in scores in terms of ages, gender, or ethnicity. These results suggest that community colleges should design programming that can help new students, particularly freshmen; to identify and to address their unconstructive thoughts with the aim of helping these students learn how to manage their anxiety upon entering college. Counselors and advisors should work more collaboratively by shifting from an individual model of delivering services to a more holistic learning approach in order to help students to become more decisive about an educational career path. 相似文献

We investigated the impact of self‐assessment training on student achievement and on computer self‐efficacy in a technology‐supported learning environment (grade 9 students using Global Information Systems software). We found that self‐assessment had a positive effect on student achievement, accounting for 25% of the variance across three measures. The treatment effect was as large for females as for males and for those with low initial self‐efficacy as it was for those with higher scores. In addition, self‐efficacy increased more in the control than in the treatment group. We interpreted the self‐efficacy results to be a positive outcome of the treatment: teachers may have used self‐assessment training to depress the inflated self‐perceptions of some teenagers. 相似文献

This article summarises research carried out between 2006 and 2008 by IPTS (Institution for Prospective Technological Studies) in collaboration with a consortium of experts from 10 member states, led by ICEGEC. The project gathered information on eLearning developments to assess drivers and barriers and to suggest implications for policy and research in the 10 member states that joined the European Union in 2004. Three examples of countries (Estonia, Hungary and Slovenia) demonstrate that, while the group is not homogeneous, commonalities can be detected. Reports show that all the EU10 countries have been catching up with the older member states in ICT penetration and skills, but large digital divides remain due to regional, social and economic divides. Educational institutions are equipped with ICT, but not always at the same level in classrooms as in EU15. Universities are using ICT in education, but mostly for material provision purposes. Enterprises seem to have higher usage of eLearning solutions than in EU15, but these are not equally available for all employees. Lack of focus and coordination in policies to support eLearning developments has been assessed to be a major barrier. In general, EU10 seems to be facing similar challenges to other European countries, although specific efforts are needed to help close the divides and engage people in lifelong learning with the new opportunities ICT could provide. 相似文献

The purpose of this study was to determine if nonrespondendents to speech communication survey research differ demographically from respondents. As a follow‐up investigation of a questionnaire study, 1,604 subjects were compared across six dimensions to establish if differences existed between respondent and nonrespondent populations. 相似文献
