Abstract:

<p>Small and Medium Size Enterprises (SMEs) constitute the backbone of many economies in the world today. This is because they are creating new jobs and contributing positively to their respective economies in which Sweden is not an exception and par-ticularly the municipality of Jonkoping. SMEs invest in IT to gain access to integration of transactions oriented data and business processes.</p><p>This thesis, motivational factors for growth in SMEs – (IT perspective) give an overview of how SMEs grow as a result of the introduction and implementation of IT.

Abstract:

Even though most clinical information systems (CIS) today are technically sound, the number of successful implementations of these systems is low. For that reason, understanding the characteristics and challenges for organizations implementing CIS is now considered key to successful information technology deployment (Lorenzi & Riley, 1997). Although theory driven information systems models and CIS studies exist, an integrated model to predict a successful CIS has not been evaluated. The purpose of this research was to evaluate the ability of a theoretically-based integrated model of CIS succes

A survey was conducted to investigate motivational and satisfaction differences between Information Systems (IS) and non-IS personnel working in various non-IS organizational departments. The motivational factors of Motivating Potential Score (MPS), Growth Need Strength (GNS), Social Need Strength (SNS), Average Psychological Score (APS), and Overall Satisfaction Score (OSS) were measured. Control for occupational group differences was achieved by classifying survey respondents into one of two job categories: Managerial or Professional/Technical. Significant differences were found in the GNS s

Abstract:

The 5th generation mobile telecommunication system (5G) is currently being specified and developed, with large expectations on throughput and efficiency. While 4G and more specifically LTE might constitute a basis of the design of the network, there are some parts that should be improved. One thing to improve is the static signalling that occurs very frequently in a 4G network, of which system information such as synchronization signals, detection of network frequencies, operators, configurations etc. is a part. It has been shown that the static signalling requires both much energy and time-fr

Abstract:

Information technology (IT) plays an increasingly important role for individuals, organizations, markets, and society as a whole. IT systems are artefacts (human made objects) designed for various purposes. Given the multiple-purpose characteristics of computers, such artefacts may, for example, support workflows, perform advanced calculations, support human communication and socialization, enable delivery of services and digital products, facilitate learning, or simply entertain. The diverging application areas for IT present a challenge to designers who, as a consequence, have to address inc

This research explores two separate but related lines of enquiry - the business value of individual applications and the social and organisational impact of information systems. From this research it is clear that information systems have immense potential to change organisations. The conventional view focuses on the value that organisations can obtain through greater efficiency or new activities made possible by specific applications. But experience suggests that many organisations fail to gain the value expected. This research was started with the aim of attaining a greater understanding of

All three of these technologies have declarative underpinnings, focusing on the ‘what’ rather than the ‘how’, which is why their combination is feasible and effective. By creating a

Background Health information systems have emerged as a major component in our response to the trends of rising demands in health care.

Abstract:

Ideology is a political and a sociological term. Thinking about 'system' makes the results of sociological thought appear relevant. The understanding of information systems (IS) as social systems or as phenomena in a social context justifies, therefore, the use of the concept of ideology in the context of IS. As a consequence of this application a series of hypotheses can be formulated about IS and the study of IS. Some of these are taken up in a thought experiment. This experiment is presented in a dialectical mould, consisting of thesis, antithesis and synthesis. In the thesis, the applicati

Patient data in health care have traditionally been used to support direct patient care.
