Voice Recognition for On-line Literacy: Continuous Voice Recognition Technology in Adult Literacy Training

This study explored whether over-the-counter continuous voice recognition software could be used to support the delivery of a standardized reading curriculum to adults with low-level literacy skills. Three primary questions were addressed in the study. First, how readily could mass-market continuous voice recognition software programs be adapted for use in adult literacy training? Second, what role(s) might the voice recognition technology play in facilitating the computer-based delivery of a standard text-based reading curriculum? And third, does the use of the voice recognition software positively affect the technological skills and computing comfort levels of adults with low-level literacy skills? Five adults with low-level literacy skills completed the computer-based curriculum, using the voice recognition software to practice and check their reading and writing efforts. A literacy tutor guided the participants through the curriculum, recorded and saved the participants' responses and videotaped the sessions for subsequent analysis. The findings reported here suggest that currently available over-the-counter continuous voice recognition technology, while essentially effective and accurate with fluent readers, is not yet ready, as a stand-alone system, to meet the needs of these adults with low-level literacy skills. The voice recognition software was most effective when it was used in the presence of a tutor. Having tutors provide on-going and immediate support to learners was a vital component of literacy training in this computer-based environment. In general the computer-based programs seemed to provide participants with a `motivational boost'. Specifically, the computer-based lessons helped develop participants' technological skills and confidence levels and promoted sustained focus on instructional tasks. Implications associated with these findings for future research with voice recognition software and adult literacy training are discussed.

Computer-Based Accountability: Implications for Training

Since the call for professional accountability in the early 1970s, counselors and counselor educators have attempted to assess counseling effectiveness, to upgrade programs as a result of assessments, and to communicate results of program assessment and change to their publics. Until recently, their efforts have been impeded by the interpersonal nature of counseling, insufficient training in research and evaluation, and available low-cost computer technology. This article addresses each of the impediments with the focus on how present computer technology, specifically computer-assisted systems, can be used to help counselors and counselor educators ethically input, store, and retrieve pertinent client and program data—data that can be used to achieve program evaluation and lead to accountable program development. The Counselor Accountability System is presented as an example of an easy-to-use computer program designed to facilitate counselor accountability.

Guidelines for the Use of Video in Libraries

A set of guidelines is proposed, based on the author's experience of video developments in libraries in many parts of the world, as an attempt to assist educational technologists and librarians to exploit and communicate video information effectively in public and academic libraries. The article also examines the reasons for using video in libraries, current international developments in video use in libraries, formats and hardware, and the relationship between educational technology units and libraries in academic institutions.     

Techniques for Creating Computer-Based Instructional Text: Programming Languages,Authoring Languages,and Authoring Systems

This article examines the use of computers to deliver instructional text. The focus is on procedures for the creation of computer-based instruction (CBI) lessons. The development of CBI lessons is separated into two aspects: the design of the lesson and the authoring of the lesson. Three primary techniques for authoring CBI lessons are the use of general-purpose computer programming languages, CBI authoring languages, and CBI authoring systems. These authoring techniques are described, including the advantages and limitations of each. Authoring systems are divided into three categories according to the type of CBI lesson they will support. Considerations are given for selecting from among the authoring techniques. Emerging trends in authoring techniques are discussed.

新时代高校意识形态话语权:特征、问题及应对

当前,高校意识形态话语表征主要体现为认知语境凸显工具理性色彩、话语表达方式蕴含符号隐喻逻辑、话语意义生成侧重凝聚思想共识、话语分析视角包含内外话语博弈。增强高校意识形态话语权,需处理好历史传统话语范式和时代全新动向、主流话语导向和话语受众特点、规范化理论传播和通俗化话语表达、中国特色话语体系和世界话语体系的矛盾关系。可以在加强顶层设计、厘清文化源流、紧扣时代脉搏、回归人本话语中探索增强高校意识形态话语权的行进路径。     

基于计算机的三维医学图像处理方法——图像分割技术

图像分割技术就是把图像中具有特殊涵义（如医学图像中的病变部位）的不同区域分开来,使每一个区域都满足特定区域的一致性的图像处理技术。基于当前医学图像分割方法研究,分割的速度和稳定性无法同时提高的问题,引入一种被称为“live-wire”的半自动的交互式范例,并对其在三雏空间上的实现建立了理论模型;同时自定义了与本文模型相关的MATLAB实现函数。     

Empirical Sample Size Guidelines for Use of Latent Difference Score Mediation

Mediation models are commonly used to identify the mechanisms through which one variable influences another. Among longitudinal mediation methods, latent difference score mediation stands out due to its unique ability to capture nonlinear change over time. However, there is limited information regarding sample size demands to achieve adequate power with this method, resulting in few applications of latent difference score mediation. To address this limitation, the current study presents empirically supported sample size guidelines for 10 common latent difference score mediation structural models and 9 unique population models. The results of this study offer researchers with a set of representative sample estimates that may be used when designing studies or seeking funding.
