Mục đích của bài báo này là để hiểu hiện tượng công nghệ thiết bị cầm tay không dây trong môi trường chăm sóc sức khỏe.

Bài báo áp dụng phương pháp hỗn hợp và phương pháp định tính với các kỹ thuật nhóm tập trung và khảo sát.

Nghiên cứu chỉ ra rằng sự sẵn sàng của tổ chức, sự sẵn sàng về công nghệ, thực hành lâm sàng, các khía cạnh xã hội cũng như sự tương thích của phần cứng mới với hệ thống hiện có, đóng vai trò quan trọng trong việc áp dụng thiết bị cầm tay không dây trong hệ thống chăm sóc sức khỏe Australia.

Nghiên cứu trong lĩnh vực này cần xem xét các tác động của công nghệ thiết bị cầm tay không dây ở cấp độ tổ chức trong môi trường chăm sóc sức khỏe và khả năng áp dụng của nó đối với các cài đặt chăm sóc sức khỏe độc đáo.

Nghiên cứu đã xác lập rằng việc truy cập dữ liệu, cải thiện giao tiếp, phát triển chính sách, truyền tải thông tin chất lượng cao và giao diện dễ sử dụng là một số yếu tố ảnh hưởng đến sự chấp nhận công nghệ không dây trong hệ thống chăm sóc sức khỏe Australia. Nghiên cứu cũng xác định những thách thức, chẳng hạn như thiếu cam kết của quản lý, trong việc thực hiện sự chấp nhận.

The purpose of this paper is to report on an action research initiative designed to facilitate the creation of shareable multimedia learning objects at a UK higher education institution. The use of multimedia learning objects in educational settings has been the subject of much interest in recent years. However, it has been suggested that a significant barrier to the uptake and use of these resources has been the lack of technical ability and support available to teachers. The Faculty of Health at Birmingham City University (BCU) was committed to the use of learning objects in the university's learning environment. However, creating innovative and exciting resources had been out of the reach of most lecturing staff due to time, financial and technical barriers. The Centre for Enhancing Learning and Teaching (CELT) at BCU collaborated with the Department of Community Health and Social Work in the Faculty of Health to produce a number of shareable learning objects to be used for enquiry‐based learning.

The paper begins by discussing some theoretical background and existing studies before going on to outline the collaboration and the pedagogy that inspired the creation of the learning objects and the processes involved in creating the resources.

The paper discusses some preliminary research results and plans for future development.

The objective of this initiative was to explore ways in which we could overcome barriers to the creation of pedagogically sound learning objects.

The aim of this study is to evaluate effectiveness of several end‐user training methods during the deployment of a new information system in an Israeli financial institution.

Four training methods, namely, frontal (lectures), simulator (e‐learning), mentor (personal guidance), and hybrid (mix of the three aforementioned methods) were all compared in terms of the number of referrals to an online helpdesk following training sessions.

A pair‐wise analysis to pinpoint the source of the differences between the various training methods indicates that all training methods are significantly different except for frontal and simulator and therefore an organization considering these two methods can select them indifferently. A combination of mentor and simulator was found to be significantly inferior to the frontal and simulator hybrid method.

The main limitation of the study is that evaluation was based on data associated with a specific organization, and thus external validity to other industries or countries is somewhat limited. Among other limitations are cross‐organizational differences in terms of: difficulty of calls, individual experience in the IS/IT area, and prior exposure to similar technologies.

Although this research does not recommend a specific training method, our findings suggest that deploying a new software system is a matter that requires early assessment by the organization and that the best results are obtained by employing the hybrid training approach.

The use of the number of referrals to an online helpdesk is a novel metric for measuring training effectiveness. The study also investigates the decline of the number of referrals over time.

The purpose of this paper is to develop an innovative information hiding algorithm.

The proposed algorithm is based on image histogram statistics. Cumulative‐peak histogram regions are utilized to hide multiple bits of the secret message by performing histogram bin substitution. The embedding capacity, otherwise known as payload, and peak signal to noise ratio (PSNR), as well as security, are the main metrics used to evaluate the performance of the proposed algorithm.

According to the obtained results, the proposed algorithm shows high embedding capacity and security at comparable PSNR compared with existing hiding information techniques.

The simplicity, security, random distribution of embedding pixels, and on‐demand high capacity are the key advantages of the proposed approach.

The purpose of this paper is to analyze the types of research published in the Association for Information Systems (AIS) basket of top journals.

This paper uses bibliographic analysis to analyze all the articles that were published in the AIS basket of top journals over a ten‐year period, from 1998 to 2007. Articles were classified based on their paradigmatic and methodological approach.

Although there is a common perception within the information systems (IS) research community that European IS research is mostly qualitative and interpretive, the bibliographic analysis reveals that the two European IS journals are not significantly different from their US counterparts. All six journals in the AIS basket are remarkably similar in terms of the types of research published.

This article is one of the first to provide a comprehensive overview of the types of research published within the AIS basket of top journals. It provides a picture of how the two European IS journals differ from their US counterparts.

This empirical study aims to understand the interrelationship among the key technology adoption factors including social influence, individual existing knowledge, and individual perceptions of technology (i.e. usefulness, ease of use, and enjoyment) and their effects on individual intention to use a free voluntary service.

The survey method is employed to collect data from universities offering the free mobile messaging service. A structural equation modeling analysis technique is used to analyze data reliability and validity in the measurement model and examine causal relationships among the constructs in the structural model.

The results show that social influence affects individual knowledge and perceptions of the service (perceived usefulness, perceived ease of use, and perceived enjoyment) and successively influences the individual intention to use the free voluntary service. This study indicates that the intrinsic value of perceived enjoyment has a greater impact than the extrinsic value of perceived usefulness in terms of its effect on individual intention to use a free voluntary service. In addition, the effect of perceived usefulness of alternative systems should be taken into account when using perceived usefulness from the technology acceptance model to predict individual's technology adoption decisions under the free voluntary setting.

This study fills the gap in the technology adoption literatures regarding the free voluntary service adoption based on social influence, individual knowledge, and individual perceptions of technology. It assists academics to understand the drivers of technology acceptance under the free voluntary setting and provides guidance for organizations to increase users' acceptability of their free voluntary services.
