Digitisation, ‘Big Data’ and the transformation of accounting information

Developments in digitisation, software and processing power and the accompanying data explosion create significant alterations, dilemmas and possibilities for enterprises and their finance function. The article discusses a model for understanding data, information and knowledge relationships. We apply the model to examine developments in strategy, organisational and cost structures, digitisation, business analytics, outsourcing, offshoring and cloud computing. We argue that organisations need to be sensitised to different types of knowledge, the challenges in creating and applying that knowledge, and be more circumspect about what can be achieved through advances in information-based technologies and software. We point to both the potential of and the complexities presented by Big Data in relation to the finance function generally and to management accounting information provision specifically. We suggest that ‘Big Data’ and data analysis techniques enable executives to act on structured and unstructured information but such action must recognise that the traditionally presumed sequential and linear links among corporate strategy, firm structure and information systems design are no longer in play. Additionally, cost structure changes are affected by developments in how data, information and knowledge can be utilised. We discuss the outsourcing and offshoring of work and their data, information and knowledge ramifications as well as those related to cloud computing. We conclude that the possibilities for the digitally enabled business create a range of ‘information literacy’ challenges as well as new possibilities for accounting information providers.

Research of models of architectures for server applications of corporate information systems

Analysis of existing models of architectures, used to design and build server applications of corporate information systems was conducted in the paper. Currently, corporate information systems are widely used to improve efficiency and minimize costs of administration. Modern level of various software offers of the server part of information system promotes the development and improvement of these systems.Therefore, the task of choosing a rational model of architecture for the server application of corporate information system is urgent.As a result of studies, it was found that non-linear models of architectures are expedient to use for corporate information systems. Modification, based on allocating from the queue those inquiries to the system, which require connection to the database for recording, was proposed. This modification has allowed to improve the system indicators such as inquiry processing time, horizontal scalability, bandwidth. Thus, more flexible model of the architecture for server applications of corporate information systems, which allows to reduce the total cost of the developed software due to more flexible load distribution on the hardware was obtained.

Software prototype for information systems’ personnel's protection analysis based on the fragment of user’s vulnerabilities profile

Complex corporate information systems are widely distributed in the modern world. Development, support and protection of similar systems require a significant amount of time and resources, besides only highly skilled experts can be engaged in the management of such systems. Information stored in such information systems has enormous value for the owners of systems therefore considerable efforts are spent for creation systems of protection of such systems from various threats to their safety. The purpose of this paper is to combine an indistinct and likelihood approach to an assessment of security of the user in relation to attacking actions of the malefactor, meaning the actions of rather elementary character ("one movement") aimed at "elementary" vulnerabilities of the user which lead directly to some action of the user.

A Support of Independent Processes Outside of Information System, Using an Ontology Driven Application

The purpose of the article is to analyze support of the independent processes, using any tool of information technology (IT) outside of the information system (IS) in the enterprise environment. The useful tool of IT could be the software (SW) ATOM, an ontology-driven web based application. Changes in IS are very expensive, complicated and risky, but it should be suggested solution omitted. The extensive literature review of the current state of the topic is added. The chosen process is innovation; the life cycle of innovation is explained: suggestion of innovation, demand for the solution of innovation, the final solution of innovation, and project for implementation of innovation. The methodology of an ontology preparation for the SW application includes design scheme of classes and associations between classes, preparation table of assignment characteristics to classes, and implementation of an ontology design in SW ATOM. The real possibility to support independent processes outside of IS using an ontology-driven application was experimentally verified and confirmed, and the result of research work could be used for any process outside of IS. Limits of the proposed solution consist of only experimental laboratory verification. For the practical use, it should be necessary first to prepare a prototype for the corporation IS in an enterprise environment.

Tracking the patient journey by combining multiple hospital database systems.

With new national targets for patient flow in public hospitals designed to increase efficiencies in patient care and resource use, better knowledge of events affecting length of stay will support improved bed management and scheduling of procedures. This paper presents a case study involving the integration of material from each of three databases in operation at one tertiary hospital and demonstrates it is possible to follow patient journeys from admission to discharge.

Data protection in the personal data processing

Processing of personal data, which is obligatory for any institution or organization, requires implementation of personal data processing information systems and definitely their security. The majority of existing information security methods and techniques is focused on the security of corporate information systems resources. Such techniques do not always take into account the special requirements for data processing. This fully applies to the processing of personal data protection, the security of which is provided by the current legislation. Approaches to the protection of personal data processed in automated information systems were discussed. The classification of threats to personal data that may occur when processing them in automated systems was brought. We considered the aims and methods of minimizing such threats including comprehensive measures to protect personal data. The ways and means of personal protection methods of personal data were considered. The priorities of forming the overall personal data protection system were defined.

The use of cloud technology in Corporate Information Systems

For automation industry, Information Technology (IT) is an essential production factor, but also a major expense post. Because cloud computing promises to deliver IT services more flexibly and cost-efficiently, it for automation industry prospectively. However, given the high degree of regulation, concerns regarding security and compliance requirements arise. In this work, provide a theoretical analysis of security problems in the context of cloud computing. This analysis is complemented by the initial results of an ongoing case study concerning the practical relevance of these problems in the industry. The analysis confirms that security issues pose notable obstacles for the adoption of cloud computing in practice, but also points to appropriate countermeasures

Change Management

The rate with which change occurs has increased dramatically over the years. At the same time, the change management literature is full of claims about the high failure rate of change implementation programmes in organisations. In this position paper a case is made that change initiatives frequently fail because they are not holistic in nature. The paper argues that change can be managed more effectively if the various interconnected and interacting elements of the system are identified, the divergent interests of the various stakeholders are recognised, and the entire change process is managed systemically. As the failures of change efforts are commonly related to human issues, as opposed to technical factors, involving all stakeholders in the change process is expected to reduce resistance and to create a higher level of psychological commitment among employees towards the proposed change. The paper then looks into the implications that this holistic way of thinking has for information systems development and argues that information systems should not be implemented as a means to solving a problem but instead be treated as a significant tool to help address a complex mix of organisational issues. Information system strategy must be in line with the organizations’ corporate strategic plan and information systems must be related to a continually changing organisational context and a turbulent business environment.

콜센터 고객정보시스템의 이용자 만족도 제고를 위한 실증 연구

Those studies in the field of Management Information Systems and the Success Model of the DeLone and McLean`s Information Systems suggest that some factors related to information systems should be developed and operated to affect the performance of the user`s personal and companies through the introduction and use of corporate information systems. The purpose of this study is put on searching for some factors which impact on user satisfaction about the customer information management systems of call center. We did conduct on a survey of 539 people who are working as a call center counseling employees as setting up a structural equation model which reflects previous research on working environment and job satisfaction, and modified DeLone and McLean`s information system success model. The results of this study are as follows. First, seven of the eleven hypotheses that three quality of the information systems might be affecting working environment, job satisfaction, user satisfaction were adopted Second, we confirmed that the working environment works as a the partial mediation and the quality of services works as a fully mediation between system/information quality and users` satisfaction. The implications of this study are that it is necessary not only to make a good working environment but also to keep improving it in order to boost the operational performance of information systems in the future.

Validation and enhancement of Australian Aboriginal and Torres Strait Islander psychiatric hospitalisation statistics through an Indigenous Mental Health Worker register

Inaccuracy in identification of Indigenous status on health records hampers collection of the good quality data required to guide policies, programs and services. This study examined the use of an Indigenous Mental Health Worker Register to assess the level of correct identification of Indigenous status and sources of error among psychiatric admissions within a regional public hospital information system. The study was conducted in 2004/2005 and 2005/2006 at the Cairns Base Hospital Mental Health Unit, Queensland, Australia, serving a population of 230,000 of which 13.2% identify as Aboriginal and/or Torres Strait Islander. Psychiatric admissions data, including Indigenous status, accessed from the hospital-based corporate information system (HBCIS) were compared with data collected through an Indigenous Mental Health Worker Register that is maintained through extensive networking. Investigation of mismatches enabled estimation of the frequency and sources of incorrect identification of Indigenous status and the impact of this on hospital statistics. Cross-validation of HBCIS data with the Indigenous Register over 2 years revealed 355 Indigenous admissions. Of the total 355 admissions, 301 (84.8%) were correctly identified and included in the hospital system, while 22 (6.2%) were designated non-Indigenous, 13 (3.7%) were 'unspecified' and 19 (5.4%) were missed through incorrect residence or admission designation. Among 1293 non-Indigenous admissions, 1.1% were incorrectly identified as Indigenous, while 25.5% of the 51 with unspecified status were found to be Indigenous. Furthermore, 45 Indigenous separations that had been missed over the previous 5 year period (1999/2000 to 2003/2004) were identified through careful examination of all those with unspecified status (n=174) and those with multiple separations of mixed designation of Indigenous status (n=15); all of the latter 15 were confirmed Indigenous by other mental health database and/or the Indigenous Mental Health Worker. Thus overall this study revealed a total of 89 Indigenous separations and 1261 occupied bed days in the 7 year period that had not be identified in the hospital information system. A novel method was used to ascertain the reliability of Indigenous status identification among mental health admissions within a hospital information system in a region with relatively high Indigenous population representation. This revealed that 85% of admissions were correctly identified over two consecutive years. Perhaps more importantly, the study confirmed a low frequency of false identification of non-Indigenous people as Aboriginal and/or Torres Strait Islander. The work has also demonstrated the value of involving Indigenous Mental Health Workers in routine processes to enhance, validate and improve Indigenous statistics and increase access to culturally informed care.

A Web-Based Wireless Access to Online Information System for NAFDAC

Wireless access technology has made much impact in the growth and development of corporate information systems. This paper presents how a web-to-database production tool was used to achieve a real time wireless access to NAFDAC corporate database. An online version of the database was created using MySQL along with both client and server side software that capture queries from and generate reports to remote mobile monitoring operator devices in real time. The client sends a request using a web browser in the WAP (Wireless Application Protocol) enabled mobile device and receives a response from the database. This is done by a web server, which supplies the response in a HTML format to the user’s mobile device. The system architecture and the developed software are presented. The system was implemented as an experimental set up in a laboratory.

Skills and Trust: A Tour Inside the Hard Drives of Computer Hackers

Stories of the exploits of computer hackers who have broken into supposedly secure government and corporate information systems appear almost daily on the front pages of newspapers and technology websites, yet we know very little about the individuals behind these headlines. Most media accounts and academic studies on hackers suffer from a number of biases that this research attempts to overcome. A case study based on the seized communication logs of ten confirmed co-offenders is used to expand our knowledge of the social norms and practices that govern interactions between malicious hackers. After presenting the data and how the material became available to the author, the remaining sections focus on the two variables that define this criminal network’s performance: skills and trust. The skills under consideration are the three different sets of cognitive and practical abilities that malicious hackers need in order to succeed financially. Monetization and social skills, in addition to technical skills, play key roles in profit-oriented malicious hacking and explain why earning a decent living in the computer underground remains a laborious endeavour, even for advanced hackers. Trust, which facilitates the diffusion of technical, monetization, and social skills and fosters collaboration, was found to be much lower in this network than is generally assumed in the literature. The need for monetization and social skills as well as the lack of trust between members may partly explain why hacker networks are so ephemeral and vulnerable to law enforcement disruption.
