Attitudes of Australian information system managers against online attackers

Examines the attitudes of Australian IS/IT managers to the concept of cyber-vigilantism. Also, it explores the policies and procedures which have been set in place by various organisations to cope with concerted attacks on their systems. It finds that although a majority of managers do approve of the concept of “striking back”, only a minority are prepared for this eventuality. There appears to be complacency about the threats posed by organised, offensive attackers.

How does organizational culture affect IS effectiveness : a culture-information system fit framework

Previous research has examined the impact of organizational culture(OC) on the implementation of many information systems. However, there is a lack of overall picture on how OC affects the effectiveness of different information systems differently. Based on the Competing Value Framework, this paper proposes a comprehensive framework to explain how the fit between organizational culture and types of IS results in different types of IS effectiveness. This framework can be used by managers to create a proper organizational culture that is compatible with the use of specific information systems.

A model for enhancing empowerment in farmers using mobile based information system

Farmers living in rural villages of Sri Lanka do not have proper access to information to make informed decisions about their livelihoods and as a result they face constant hardships in their lives. They use mobile phones to communicate but these are not currently connected to the Internet. We are investigating how to provide personalized information to farmers with the aim of empowering them to make informed decisions and take appropriate actions. In this paper we propose an empowerment model that has been designed to achieve their goals which have been identified using a scenario-based approach. The model examines several empowerment processes and supporting tools that would help them to achieve their goals with the hope that they would have an increased sense of control, self-efficacy, knowledge and competency. This empowerment model is applied to the development of a mobile based information system that is being developed by an international collaborative research group to address the issues of the farmers.

What drives the end user to build a feral information system?

A Feral Information Systems (FIS) is any technological artefact (e.g. spreadsheets) that end users employ instead of the mandated Enterprise System (ES). ES proponents suggest that the installation of an ES will boost productivity. However, Production Possibility Frontier theory provides insights as to why the introduction of an ES may instead suppress an end user's productivity. Structuration Theory offers insights that explain how certain end users may have access to powerful resources. Rather than submitting to the ES, the end user can employ FIS to block or circumvent aspects of the ES. Further, the concept of life chances helps explain why individuals may or may not develop the core skills required to construct an alternate to the ES, the FIS. In relation to the ES usage, an end user may adopt one of four Modes of Operation, namely: Submit, Dismiss, Hidden, or Defiant.

Framework for a Residential Energy Information System (REMIS) to promote energy efficient behaviour in residential energy end users

Previous studies on residential energy end use behavior reported significant reduction in energy end use of 7% to 24% when feedback is used to modify behavior in an energy efficient manner. However, most feedback systems investigated in previous studies have not benefited from advanced information systems (IS). IS can shape energy efficiency behavior by providing real-time feedback on energy consumption, cost and environmental impact. Such systems represent a new and less-researched subfield of energy informatics. This paper provides a conceptual framework for showing the potential use of IS to modify residential energy use behavior towards better energy efficiency. The framework builds on research in residential energy end use, in particular energy end use behavioral model. It provides conceptual inputs for a blue-print to develop a residential energy management information system (REMIS) and also highlights the use of new information and communications technologies (ICT) that had not been widely used, setting the grounds for further research in this area.

Exploring the global and local networks of national information system integration initiatives : a case study of national cultural collection integration from an actor-network perspective

Australian Museums Online (AMOL) was the earliest attempt to make Australia’s distributed cultural collections accessible from a single online resource. Despite early successes, significant achievements and the considerable value it offered certain groups, the project ran into operational difficulties and was eventually discontinued. By using Actor-Network Theory and analysing the global and local actor-networks, it is revealed that although the project originated from large, state museums, buy-in was restricted to individuals, rather than institutions and the most significant value was for smaller, regional institutions. Furthermore, although the global networks that governed the project could translate their visions through the local production networks, because the network’s underlying weaknesses were never addressed, over time this destablised the global networks. This case study offers advice for projects attempting to consolidate data sources from disparate sources, and highlights the importance of individual actors in championing the project.

Use of geographical information system and remote sensing techniques for planning culture-based fisheries in non-perennial reservoirs of Sri Lanka

 The presence of a wide areal extent of small-sized village reservoirs offers a considerable potential for the development of culture-based fisheries (CBFs) in Sri Lanka. To this end, this study uses geographical information systems (GISs) and remote sensing (RS) techniques to determine the morphometric and biological characteristics most useful for classifying non-perennial reservoirs for CBF development and for assessing the influence of catchment land-use patterns on potential CBF yields. The reservoir shorelines at full water supply level were mapped with a Global Positioning System to determine shoreline length and reservoir areal extent. The ratio of shoreline length to reservoir extent, which was reported to be a powerful predictor variable of CBF yields, could be reliably quantified using RS techniques. The areal extent of reservoirs, quantified with RS techniques (RS extent), was used to estimate the ratio of forest cover plus scrubland cover to RS extent and was found to be significantly related to the CBF yield (R2 = 0.400; P < 0.05). The results of this study indicated that morphometric characteristics and catchment land-use patterns, which might be viewed as indices of biological productivity, can be quantified using RS and GIS techniques. © 2014 Wiley Publishing Asia Pty Ltd.

Soil erosion fragility assessment using an impact model and geographic information system

A study was taken in a 1566 ha watershed situated in the Capivara River basin, municipality of Botucatu, São Paulo State, Brazil. This environment is fragile and can be subjected to different forms of negative impacts, among them soil erosion by water. The main objective of the research was to develop a methodology for the assessment of soil erosion fragility at the various different watershed positions, using the geographic information system ILWIS version 3.3 for Windows. An impact model was created to generate the soil's erosion fragility plan, based on four indicators of fragility to water erosion: land use and cover, slope, percentage of soil fine sand and accumulated water flow. Thematic plans were generated in a geographic information system (GIS) environment. First, all the variables, except land use and cover, were described by continuous numerical plans in a raster structure. The land use and cover plan was also represented by numerical values associated with the weights attributed to each class, starting from a pairwise comparison matrix and using the analytical hierarchy process. A final field check was done to record evidence of erosive processes in the areas indicated as presenting the highest levels of fragility, i.e., sites with steep slopes, high percentage of soil fine sand, tendency to accumulate surface water flow, and sites of pastureland. The methodology used in the environmental problems diagnosis of the study area can be employed at places with similar relief, soil and climatic conditions.
