Cognitive engagement with a multimedia ERP training tool: Assessing computer self-efficacy and technology acceptance

Computer self-efficacy (CSE) is a person's judgment of his or her ability to use a computer system. We investigated cognitive engagement, prior experience, computer anxiety, and organizational support as determinants of CSE in the use of a multimedia ERP system's training tool. We also examined the impact of CSE on its acceptance. We determined the benefits of a sequential multi-method approach using structural equation modeling and neural network analysis. High reliability predictions of individual CSE were achieved with a sequential multi-method approach. Specifically, we obtained almost 68% perfect CSE group prediction overall, with almost 85% perfect CSE group prediction using fuzzy sets and over 94% accuracy within one group classification. The resulting CSE assessment and classification enables management interventions, such as allocating users to appropriate instruction for more effective training.

The dual nature of prior computer experience: More is not necessarily better for technology acceptance

It is often presumed that individuals with greater computer experience will easily adopt new or updated replacements of existing information technology. To examine this assumption, this study reviews prior computer experience research, identifies two key dimensions of computer experience i.e. computer use and computer proficiency and evaluates their effects individually. Analysis of survey data from 737 respondents using structural equation modeling indicates that each dimension had differential effects on behavioral intentions to use a newly introduced internet-based technology with computer use having curvilinear effects on adoption intentions. Implications for research and practice are discussed.

Teachers perceptions of the availability of computer hardware

Abstract Mathematics teachers in 40 secondary schools in the Greater Manchester region were sent questionnaires asking them, amongst other things, to comment on the availability of various forms of computer hardware for use in their teaching of mathematics. Seventy-five replies were received and analysed. In respect of a single computer in a classroom –a provision which teachers seem to see as being of little benefit–most believe they can achieve bookable access although spontaneous availability is unlikely for all but a minority. For computer suites–the more favoured provision–even booking in advance guarantees access for less than half of all teachers with spontaneous access granted to less than one teacher in ten. Some implications of these findings and possible ways forward are discussed.     

The acceptance and use of computer based assessment

The effective development of a computer based assessment (CBA) depends on students’ acceptance. The purpose of this study is to build a model that demonstrates the constructs that affect students’ behavioral intention to use a CBA. The proposed model, Computer Based Assessment Acceptance Model (CBAAM) is based on previous models of technology acceptance such as Technology Acceptance Model (TAM), Theory of Planned Behavior (TPB), and the Unified Theory of Acceptance and Usage of Technology (UTAUT). Constructs from previous models were used such as Perceived Usefulness, Perceived Ease of Use, Computer Self Efficacy, Social Influence, Facilitating Conditions and Perceived Playfulness. Additionally, two new variables, Content and Goal Expectancy, were added to the proposed research model. Data were collected from 173 participants in an introductory informatics course using a survey questionnaire. Partial Least Squares (PLS) was used to test the measurement and the structural model. Results indicate that Perceived Ease of Use and Perceived Playfulness have a direct effect on CBA use. Perceived Usefulness, Computer Self Efficacy, Social Influence, Facilitating Conditions, Content and Goal Expectancy have only indirect effects. These eight variables explain approximately 50% of the variance of Behavioural Intention.     

The effect of computer self-efficacy on enterprise resource planning usage

Global competition has impelled numerous organisations to employ enterprise resource planning (ERP) systems, although quite frequently without success. Studies have demonstrated that a major factor for failure is employee resistance in organisations using these systems. Exactly the factors that facilitate ERP adoption among users have seldom been identified. This study examines the usage behaviour of a sample of users of the new technology of ERP system using a technology acceptance model (TAM). Furthermore, this paper incorporates an additional behavioural construct, computer self-efficacy (CSE), to improve the predictive value of the original TAM model, named revised TAM. Additionally, the structural equation model (SEM) is used to verify the causal relationships between variables. Analytical results confirm that not only is the TAM appropriate for explaining the use of ERP, but that incorporating CSE enhances the power of the model.

Organisational computer supported collaborative learning: the affect of context

The purpose of this introduction is to provide a brief overview of the articles in this special issue and also a framework for understanding, designing and evaluating strategies for co-operative learning in the workplace and in educational environments. The special edition is divided into two parts—Issue 1: Computer Supported Collaborative Learning in Formal Education, and Issue 2: Computer Supported Team and Organisational Learning in Workplaces. In general, Issue 1 focuses on collaborative learning in primary and secondary schools and in the University setting. Issue 2 is meant to focus on learning in complex and often highly stressful work situations which mostly require intensive communication in groups or teams and in each case allow for learning in the wider organisation. This introduction outlines a set of themes that can be found in the following papers and traces briefly how each paper fits within each discussion.     

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.

基于关键字的单协议分类

网络协议是网络通信中一系列标准的集合,未知协议的识别和分析对网络监管、保障网络安全具有重大意义。协议识别技术多种多样,但大都不适用于二进制的协议识别。在此针对现有的协议识别技术的局限性,提出了一种在双方单协议通信环境下的多种类型二进制数据帧的协议识别方法。该方法首先利用n-gram技术对数据帧进行分割,然后利用无监督的特征选择算法提取特征串集合,从而利用聚类算法实现协议消息的识别。最后在ICMP上对该方法进行评估,消息识别的准确率和召回率均可达到90%以上。
