电脑病毒的预防

电脑病毒是一种人为设计的、具有类似于人类病毒传染特性的、有很强破坏力的电脑程序。电脑病毒通常都有一个感染、潜伏、发作的过程,只有当某个特定的条件满足时才会爆发。如名为“米开朗基罗”（亦称米氏病毒）的病毒必须在电脑内部时钟运行到３月６日时才开始破坏电脑硬盘上的数据;而“黑色星期五”病毒的发作条件是日期为１３日并且同时又是星期五。因为,电脑本身不会自己滋生出病毒,病毒程序也只有被运行时才繁衍、传染。所以,对于没有联网操作的单台电脑来讲,感染病毒的唯一途径就是使用了已带有电脑病毒的“不洁”软盘或光盘。自从发…     

让你的电脑百毒不侵

电脑病毒——听过吧,这是大多数电脑使用者再熟悉不过的名词了。也许有些人从来没遇到过病毒,但病毒对电脑的危害性绝对不能轻视,在电脑和网络都如此普及的今天,即使你不是一个电脑高手,也应该了解一些电脑病毒的基础知识。

Computer phobia and computer self-efficacy: their association with undergraduates’ use of university computer facilities

Extensive development in universities’ provision of computer facilities may have negative consequences for students prone to computer avoidance. In the present study, undergraduates (N = 363) completed self-report measures on computer phobia and self-efficacy. Results demonstrate that many students follow previous trends by continuing to report levels of computer phobia within the higher parameters of self-report measures. Students who reported either high computer phobia or low computer self-efficacy were less likely to maximise their use of university computer facilities. Moreover, a range of background measures – initial computer experience, regular home use, successful completion of a computer course and introductory tutor’s characteristics – all impacted statistically on self-report responses. Results are discussed with reference to the increasing responsibility placed on students to acquire ICT skills.     

Assessing the computer attitudes of students: An Asian perspective

Research has found that computer attitudes play a key role in influencing the extent to which students accept the computer as a learning tool and in determining the likelihood that computer will be used in the future for learning and study. A sample of 183 students reported their computer attitudes using a Likert-type questionnaire with three subscales, computer importance, computer enjoyment, and computer anxiety. One-way MANOVA revealed no significant differences in computer attitudes by gender although male students reported more positive towards the computer than female students. There were significant differences between students who own computers at home and those who do not and students who own a computer at home also reported a lower level of computer anxiety compared to those who do not.     

Comparing attitudes towards computer usage by undergraduates from 1986 to 2005

The importance and use of computers has increased dramatically over the last two decades. The Attitudes Towards Computer Usage Scale (ATCUS) was developed in 1986 [Popovich, P. M., Hyde, K. R., Zakrajsek, T., & Blumer, C. (1987). The development of the attitudes toward computer usage scale. Educational and Psychological Measurement, 47, 261–269.] and used in a variety of settings over the years. In order to examine how computer attitudes have changed from 1986 to 2005, the ATCUS was given to 254 male and female current undergraduate students. When comparing the 1986 with 2005 results, the amount of time spent using a computer was still positively related to computer attitudes; however, the number of college computer courses was not. There is no longer a significant relationship among any of the factors with college computer courses. Males and females no longer significantly differ in their attitudes toward computers, number of college computer courses, amount of time spent using computers, or degree of self-reported computer anxiety. Implications are discussed.

Computer use and the gender gap: The issue of access, use, motivation, and performance

Since the beginning of computerization, it has been of interest whether there are differential effects on computer behavior, in particular in terms of computer access, computer use, and motivational variables, such as computer self-efficacy. The current research addresses the questions if the gender-related differences in this respect persist to the present day and if there is also a difference in actual performance characteristics. A sample of 48 university students (23 male) was administered a technology self-efficacy questionnaire, a survey on computer access, recorded a user diary, and turned in a computer task. Results show that the gender gap is closing as far as computer access and self-efficacy are concerned. Also, female and male students report comparable amounts of computer usage for their studies. User behavior appears to be gender-specific as males spend more time at the computer for personal purposes. There is also some evidence that male students outperform female students at a computer task (remastering of Power-Point slides). Conclusions for creating computer-based learning environments are discussed.     

计算机技术现状及未来发展分析

The Computer Aversion, Attitudes, and Familiarity Index (CAAFI): A validity study

This study’s purpose was to provide additional psychometric data on the Computer Aversion, Attitudes, and Familiarity Index (CAAFI). The CAAFI is comprised of 40 items, yielding a total score and four factor scores with 10 items each (one familiarity, one attitudes, two aversion). The measure was administered to a sample of undergraduate psychology students (N = 293) along with the Computer Understanding and Experience Scale, the Computer Attitude Scale, and the Computer Aversion Scale. The factor structure of the CAAFI was supported via confirmatory factor analytic procedures and analysis of internal consistency reliability coefficients. In relation to the other measures of computer-related constructs, the strongest validity support was found for the CAAFI total score and Factors 1 (computer familiarity) and 3 (computer aversion-discomfort), followed by Factor 2 (computer attitudes). With regard to Factor 4 (computer aversion-fear), given the results of the analyses the decision was made to remove these items from the CAAFI in order to enhance the measure’s psychometric properties and practical utility.

Computer crime — Risk management and computer security

An analysis will be made on 95 cases of computer fraud and over 60 cases of computer crime reported in the U.K. from various private and public sources to establish the pattern of abuse and the modus operandi in various crime perpetration — who are the victims, who are the computer criminals, size of loss, penalties and detection and lessons learnt from the reported cases.The paper moves on to discuss the various options of risk control and crime prevention, risk analysis and business impact review, and how to set a budget for control of abuse.The paper closes with a discussion of the future implications from the proliferation of personal computers, office systems and distributed processing. What advantages would the future criminal gain from these activities? What would the auditor or security manager have to do to combat the potential new crime wave?
