Abstract Background: Organisations nowadays operate in a very dynamic environment, and therefore, their ability of continuously adjusting the strategic plan to the new conditions is a must for achieving their strategic objectives. BSC is a well-known methodology for measuring performances enabling organizations to learn how well they are doing. In this paper, “BSC for IS” will be proposed in order to measure the IS impact on the achievement of organizations’ business goals. Objectives: The objective of this paper is to present the original procedure which is used to enhance the BSC methodology in planning the optimal targets of IS performances value in order to maximize the organization's effectiveness. Methods/Approach: The method used in this paper is the quantitative methodology - linear programming. In the case study, linear programming is used for optimizing organization’s strategic performance. Results: Results are shown on the example of a case study national park. An optimal performance value for the strategic objective has been calculated, as well as an optimal performance value for each DO (derived objective). Results are calculated in Excel, using Solver Add-in. Conclusions: The presentation of methodology through the case study of a national park shows that this methodology, though it requires a high level of formalisation, provides a very transparent performance calculation.

In this study, it was aimed to transfer Piri Reis’s 1513 world map into an interactive and dynamic environment to reflect social participation and map literacy skills of pre-service social studies teachers, to determine the reflection of the skills from the views of the pre-service teachers and the information they have structured in the database. In this sense, the virtualized map was integrated into a geographical information system application developed by the researcher. This research, in which a qualitative research approach was adopted, was carried out as a case study. The views of the pre-service teacher’s skills and environment were evaluated with content analysis, and their reflection skills were evaluated with descriptive analysis. Eighteen students determined with the maximum diversity sampling method participated in the study, which lasted for two and a half months. It was concluded through the findings obtained from the views of pre-service teachers that social participation and map literacy skills could be reflected in various dimensions, the map could be interpreted collectively with social participation and map literacy skills, and cultural heritage could be transformed into a form of instructional technology. It was determined that the general views of pre-service teachers regarding this environment were mostly positive and the environment beneficially enabled them to discover cultural heritage, developed various skills and gave different perspectives. Still, some pre-service teachers remained passive in the environment. In the findings obtained from the database of the virtualized map, it was determined that the sub-dimensions of map literacy with social participation skill were mostly reflected in the form of understandinginterpreting symbols, finding location - coordinate, measuring distance, finding direction, reading - interpreting a map, but not reflected in using scales.

The results of laboratory experiments on nitroglycerine toxicity detected by histological and cytological indices are presented, using Danio rerio as a case study. For the first time, there are shown the changes in liver and kidneys, both at tissular and cellular levels, induced by administered concentrations of nitroglycerine. The results obtained appear to be important for water bodies’ preservation and elaboration of MPC standards. The intake of nitroglycerine into water bodies is due, mainly, to discharge from pharmaceutical enterprises, demolition works, and outflow from explosives storehouses. Fish turned out to be sensitive to nitroglycerine as indicated by histological and hematological indices. Maximum permissible concentration, MPC, for Danio rerio is determined to be equal to 0.5 mg/l.

To obtain a sustainable competitive advantage in the dynamic environment, it is necessary for Chinese high-tech enterprises to focus on their technology habitual domains in formulating ambidextrous innovation strategy. This study integrates technology habitual domain, exploratory innovation and exploitative innovation within a framework and explores the influence mechanism among them. Based on an in-depth case study on KTE, representing a high-tech enterprise in China, we have several findings. Firstly, we depict the evolution mechanism of technology habitual domain; secondly, we find that the high-tech enterprise’s technology habitual domain will cultivate and develop the firms’ dynamic capabilities; and thirdly, the expansion of technology habitual domain will promote exploitative innovation, while the transformation of technology habitual domain will promote exploratory innovation. These findings can be useful guidance for high-tech enterprises in China who are aiming to achieve ambidextrous innovation to better adapt to the turbulent environment, and thus achieving sustainability.

Commercial Off The Shelf

This article reports on the use of Commercial-Off-The-Shelf (COTS) software for developing a dynamic environment for an online public access catalogue (OPAC). COTS products are widely used throughout the industry. While there are many potential benefits, use of COTS components is also fraught with pitfalls. The research on creating a dynamic environment for OPACs is based on the previous work in this area, Public Access Catalogue Extension (PACE), which was developed with custom-based software programs. Although in the previous research project all the programs were successfully developed in C and C++, the present project relied very little on original and custom programming. Instead, a number of COTS products were used to construct the dynamic environment: Macromedia Director, 3D Dreams, Extreme 3D, Crossroads, and Easybase. These COTS products were chosen for their ability to produce the desired results, their availability at reasonable costs, and their capability to integrate with one another. A small experimental database with one hundred MARC records was constructed in Easybase. Models were built in Extreme 3D and converted to 3D Studio using Crossroads. These models were used in 3D Dreams to create three-dimensional environments for use in Macromedia Director.

The concept of communities of practice (CoPs) has rapidly gained ground in fields such as knowledge management and organisational learning since it was first identified by Lave and Wenger (1991) and Brown and Duguid (1991). In this article, we consider a related concept that we have entitled “communities of implementation.” Communities of implementation (CoIs) are similar to communities of practice in that they offer an opportunity for a collection of individuals to support each other and share knowledge in a dynamic environment and on a topic in which they share interest. In addition, and to differentiate them from CoPs, a community of implementation extends the responsibilities of a CoP by having as its focus the implementation of a programme of change. This may well extend to designing the change programme. Thus, whereas a main purpose of a CoP is to satisfy “a real need to know what each other knows” (Skyrme, 1999) in an informal way, we argue that a main purpose of a community of implementation is to “pool individual knowledge (including contacts and ways of getting things done) to stimulate collective enthusiasm in order to take more informed purposeful action for which the members are responsible.” Individual and collective responsibility and accountability for successfully implementing the actions/change programme is a key feature of a community of implementation. Without these pressures the members might lower the priority of implementation, allowing competing priorities to dominate their attention and resources. Without responsibility and accountability, the result is likely to be (at best) an organisation which has not begun a change programme, or (at worst) an organisation which is stuck halfway through another failing initiative. To achieve these additional objectives beyond those of a CoP, the CoI needs to provide heightened support to its members. In fact often the members will collectively strategise the development and implementation of the change programme they are leading in the organisation. Other concepts similar to CoPs have appeared in the literature, for example “communities of knowing” (Boland & Tenkasi, 1995), but none have a specific focus on implementation. Perhaps the closest example of a CoI, as suggested by our definition, is reported by Karsten, Lyytinen, Hurskainen, and Koskelainen (2001) who describe a CoP in a paper machinery manufacturer which seems to have the necessary focus on implementation. The theoretical aspects of this article will explore the relationship between CoPs and CoIs, and the needs for different arrangements for a CoI. The practical aspect of this article will consist of a report on a case study of a CoI that was successful in its implementation of a programme of change that aimed to improve its organisation’s knowledge management activities. Over two years the CoI implemented a suite of complementary actions across the organisation. These actions transformed the organisation and moved it towards achieving its ‘core values’ and overall objectives. The article will explore: the activities that formed and gelled the community, the role of the community in the implementation of actions, and experiences from key members of this community on its success and potential improvements.
