An exploratory study on the perspectives of prospective computer teachers following project-based learning

This study investigates perceptions of 29 prospective teachers about a course based on Project-Based Learning (PBL) approach. The course, ‘Authoring Languages in PC Environment (B-320)’ lasted in 14 weeks in fall semester of 2004–2005. In this course each prospective teacher carried out a project that requires designing and developing courseware individually. This study is qualitative in nature and data were collected through an open ended questionnaire composed of seven items and analyzed by content analysis technique. The results show that prospective teachers found PBL as an effective way of learning. It also suggests that when efficient guidance about technical issues and time management is provided, PBL approach can be successfully implemented in computer related courses such as programming language and web designing.     

Towards a better understanding of partnership attributes: An exploratory analysis of relationship type classification

In recent years the creation of partnerships has been espoused by academics and practitioners but despite extensive writing in the area of characterizing partnerships the nature and attributes of partnerships are still only poorly understood. This is due to a lack of empirical testing of the factors that distinguish partnerships from other relational forms and a limited research focus on characteristics that distinguish between polar relationship types. Using a framework developed from the political economy literature this exploratory study draws on an empirical base of 155 supplier questionnaires and uses multiple discriminant analysis to identify attributes of buyer-supplier relationships that most effectively discriminate between relationships classified by suppliers as having limited coordination, being highly coordinated or best described as a partnership. The results indicate that 8 of the 10 attributes of buyer-supplier relationships included in the framework differ significantly across relationship type.     

Successful integration of R&D functions after acquisitions: An exploratory empirical study

Do the ‘grand’ strategic context characteristics of an acquisition (e.g., business relatedness of buyer and target) deter-mine the integration success of R&D functions after a takeover? Are acquisition management interventions (i.e., the way in which the integration process is man-aged) the key levers shaping integration success of R&D functions after a change in corporate ownership? Little non-anecdotal empirical data are available to answer these questions. Therefore, they were addressed with a sample of 92 acquisitions between German firms in 1988. Overall, use of management interventions which were designed to promote learning opportunities and reduce uncertainty for acquired employees (e.g., small group meetings to exchange information) but also degree of centralization of strategic R&D decisions in the hands of the acquirer were significantly positively related to integration level of R&D functions of both firms after an acquisition. With the exception of relative size of acquiree, strategic acquisition context characteristics were not directly related to R&D integration success. These characteristics may not be as important in shaping R&D integration success as management practitioners and scholars have thought.     

An exploratory study of factors affecting the failure of local small and medium enterprises

There is increasing recognition of the potential contribution of local small and medium enterprises (SMEs) towards employment and economic growth in Singapore. Unfortunately, SMEs tend to have a high mortality rate. A survey was conducted among owners or managers of local SMEs to identify factors perceived as important in affecting business failures. The research results indicate that endogenous factors were viewed by respondents as more critical in causing SME failures than exogenous factors. Important exogenous and endogenous factors in specific areas were identified.Lau Geok Theng is Senior Lecturer, Department of Marketing, National University of Singapore, 10 Kent Ridge Crescent, Singapore 0511, tel: (65) 772-3179, fax: (65) 779-5941.

Towards a framework of customer value assessment in B2B markets: An exploratory study

This paper examines the key processes and activities of customer value assessment in business-to-business (B2B) markets. Given that an increasing number of B2B firms are providing combinations of products and services, or integrated solutions, the present study examines customer value assessment from the solution supplier's perspective. Specifically, based on an exploratory field study and in-depth interviews with 18 managers in three different firms, the present study identifies five key processes (i.e., value potential identification, baseline assessment, performance evaluation, long-term value realization, and systematic data management) and 11 related activities involved in customer value assessment in B2B markets, and integrates them into a managerially grounded framework. The findings from this study contribute to the literature on customer value and solution research, and provide useful insights for managers on how to assess the value delivered by their offerings to customers.     

Covered interest arbitrage with transaction costs: An evidence from the Hong Kong foreign exchange market

This paper deals with the effects of transaction costs on the efficacy of covered and one-way interest arbitrage under the linked exchange rate system in the Hong Kong foreign exchange market. First, we examine the arbitrage opportunities in the swap market and in domestic and foreign securities markets. Second, we measure the profitability of covered interest arbitrage and one-way arbitrage. Empirical findings have shown that allowing for transaction costs, covered interest arbitrage seems to entail less unexploited opportunities for profit. However, there exists a great deal of unexploited profit opportunities in one-way arbitrage in the Hong Kong financial market.We are grateful to two anonymous referees and the editor for their helpful comments on an earlier version of this paper.     

Organisational culture in the age of the Internet: an exploratory study

Through an exploratory study of a large financial services organisation, this study finds that the idiosyncratic nature of the Internet and Internet operations point to a range of implications for both the interaction of organisational subcultures and the internal and external perceptions of organisational culture.     

Organizational culture and coopetition: An exploratory study of the features,models and role in the Polish Aviation Industry

This study explores the importance of organizational culture for coopetition, and identifies the cultural profile of coopetitors operating within an innovation network. Although organizational culture's role in interorganizational collaboration is long established, coopetition settings have not received a similar attention. This exploratory study sheds light on the role of culture for coopetition, and scrutinizes organizational culture using the Competing Values Framework. Our findings suggest cultural differences between coopetitors versus non-coopetitors. Coopetitors display a cultural profile typical to hierarchy, as they describe themselves as more stable than flexible and more internally than externally focused in their strategic orientation. Interestingly the culture model typical for coopetitors, has been identified as the most distant for non-coopetitors, while the second typical model for non-coopetitors i.e. adhocracy has been identified as the most distant for coopetitors.     

Relational and transactional factors as hybrid criteria for buyer project selection (BPS): An exploratory study from industrial suppliers' perspective

Working off the literature in selection studies, evolving from supplier selection, to buyer selection, to selection as transaction embedded in relationality, this study asks how industrial suppliers actually engage in buyer project selection (abbreviated as “BPS”). Semi-structured interviews and focus group discussions were used to construct and pilot-test a new BPS instrument among electronics executives in Taiwan. A mail survey using the new BPS instrument subsequently resulted in three significant research findings. First, the five BPS factors uncovered a hybridity thesis: factors from the transactional paradigm and the relational paradigm co-existed side by side. Second, even though suppliers engaged in project selection, the majority of the respondents' firms lacked clearly articulated formal BPS criteria. Third, relational satisfaction, more than perceived power, significantly impacted project selection; and project economic contribution, more than the other four BPS factors, played a substantive role in assessing relationality. Our research hopefully will help practitioners to recognize the need of BPS formalization, making a rich literature related to the co-existence/hybridity of transactional and relational approaches in project marketing and management relevant to Taiwan, China and the broader Asian business world in the future.     

Integration of third parties within existing dyads: An exploratory study of category management programs (CMPs)

In this study, we focus on the pursuit of cross-functional integration between suppliers and retailers along the different phases of a collaborative project. More specifically, we explore why and how, a supplier and retailer would want to shift the locus of integration from the dyadic to the network level by adding a third party to an ongoing relationship.A case study is developed to analyze the process of integration in the context of category management programs. The analysis reports on a program developed by a regional retailing chain based in the south of Italy, with the collaboration of a national coffee blends supplier and a third-party leader in the market analysis service business.The findings offer a novel view of third parties' role, which broadens the scope from a typical, initial support of negotiations to an evolving modality of intervention during the different phases of the collaborative project. More precisely, the third party enables the sequential and joint activation of alternative forms of interaction between the parties, which is pivotal for enacting the integration mechanism that is most suitable for each program phase.These findings offer a rich set of insights for the analysis of integration within distribution channel and supply chains, as well as for category management and, more generally, for knowledge management in marketing relationships.

An investigation into the effect of systematic design methods in craft,design and technology (CDT)

This paper has grown out of a long standing personal concern that the current approaches to design teaching are too narrowly based and that they can distort the very activity that they set out to encourage. A survey of the comments made in Examiner's Reports of pupil's work in public design examinations during 1986 & 1987 provides some insight into the difficulties that pupils experienced in carrying out their design activities.Design activity in schools developed from the beginnings initiated by the curriculum development projects of the late 1960's and early 1970's. These put forward methodical approaches to designing which have become widely used in UK secondary schools and which are now firmly embedded in the publications and project assessment framework of the current national examinations.The present study suggests that, while these methodical approaches clearly work, they imply a logical progression of thought which does not necessarily parallel the pattern of human thinking. It is recognised that pupil's design folios written up at the end of a project can be made to describe a logical, systematic procedure which has more to do with the assessment framework than the actual developments of design ideas during the project. Indeed, teachers and candidates were being actively encouraged to base their work on these structured frameworks:The actual style and quality of the folder presentation is also important. This is particularly so when working to a detailed mark scheme. Certainly it is easier to mark a folder which broadly follows the pattern of the mark scheme than one which is very erratic. Teachers are advised as to the advantages of using the mark scheme as a teaching tool and as a guide for folder presentation. NEA, 1986.Finally, the paper examines some more recent developments in the procedural models of design activity and the way in which professional designers approach their work. These insights provide an indication of the way forward for school design work and its assessment.     

The effect of compensation program and structure on sbu competitive strategy: A study of technology-intensive firms

In this paper we examine the impact various compensation programs have upon business-level strategy for technology-intensive firms. Similarly, we examine the effect of centralization of R&D and non-R&D decision-making, formality of procedures, and SBU size on competitive strategy. Analysis of data from 79 SBUs suggest that there is a resource trade-off between marketing-oriented strategies and R&D-oriented strategies, and that managers who operate under certain types of compensation programs will tend to favor R&D/innovation strategies and capital investment over other alternatives. Structure and competitive position also appear to play a significant role in determining technology and investment strategy.

Indicators of discontinuous technological change: an exploratory study of two discontinuities in the machine tool industry

The objective of this paper is to explore the extent to which a set of indicators of technological and industrial change can act as warning signals for technical change. A particular kind of technical change can give a new substitute such price/performance attributes that it is taken into the reach of mass market segments. Two processes of discontinuous technical change in the machine tool industry are analysed using patent data, bibliometrics, data on new entrants, relative price changes and diffusion data. In the first case (the transition from conventional to CNC machine tools) relative prices and new entrants were the first indicators to react whilst patents and bibliometrics increased in activity in parallel with the large scale diffusion of CNC machine tools. In the second case (the transition from CNC machine tools to flexible manufacturing systems) new entrants and publishing preceded the large scale diffusion by some years. The different patterns between the two cases and between these and what can be found in the literature, suggest that more work needs to be done to understand the conditions under which changes in each of the indicators can be used as a warning signal. The paper is concluded by a brief discussion which may form the basis for some further work in that direction.     

Auctions with toeholds: An experimental study of company takeovers

We run experiments on English Auctions where the bidders already own a part (toehold) of the good for sale. The theory predicts a very strong (“explosive”) effect of even small toeholds. While asymmetric toeholds do have an effect on bids and revenues in the lab, which gets stronger the larger the asymmetry, it is not nearly as strong as predicted. We explain this by analyzing the flatness of the payoff functions, which leads to large deviations from the equilibrium strategies being relatively costless. This is a general fundamental weakness of this type of explosive equilibria, which makes them fail when human players are involved. Our analysis shows that a levels of reasoning model explains the results better where this equilibrium fails. Moreover, we find that although big toeholds can be effective in a takeover battle, the cost to acquire them might be higher than the strategic benefit they bring.     

Characteristics and mobile Internet use intensity of consumers with different types of advanced handsets: An exploratory empirical study of iPhone,Android and other web-enabled mobile users in Germany

This work explores personal characteristics and mobile Internet (MI) use behaviors of consumers equipped with four distinct types of advanced handsets for accessing the Internet via cellular radio infrastructures of mobile network operators (MNO). Furthermore, it investigates the extent to which personal and mobile appliance characteristics explain variance in actual MI use intensity. Data on two demographic variables, three MNO relationship characteristics and actual MI use intensity (average monthly volume of mobile IP traffic generated by a subscriber in May and June 2011) of 9321 adult consumers with a flat MI pricing scheme are extracted from customer files of the German subsidiary of a large international MNO. 959, 2213, 2410 and 3739 of the sample members use an Apple iPhone 3, an Apple iPhone 4, a model running with Google’s Android operating system (OS) and other MI-enabled mobile OS/phone types, respectively. Compared to the adult population in Germany, persons at least 50 years of age are clearly underrepresented among MI adopters with the four studied device types. Differences between the four phone type groups with regard to gender, age, time from enrollment and MI use experience emerge as statistically significant, but they achieve only minor substantial relevance. MI use intensity is highly positively skewed: In each of the four appliance groups, a small number of users disproportionately add to the total MI traffic generated by the subjects. Consumers’ advanced OS/handset type strongly contributes towards explaining MI use intensity variance. iPhone subscribers generate more traffic than Android customers who in turn show a higher MI activity level than individuals running other web-enabled mobile models. Age is the only studied personal characteristic consistently showing a (negative) association with MI usage, which both is statistically and materially significant. Conclusions are drawn for MNO on MI marketing issues. Implications of study limitations for research on MI adoption and use behaviors on the MI are also outlined.     

Implementation of Key Account Management: Who, why, and how?: An exploratory study on the current implementation of Key Account Management programs

Key Account Management, as currently described in relationship marketing literature, is an important approach to creating value, by implementing specific processes targeting most important customers. This exploratory study contributes to the understanding of Key Account Management by focusing on factors influencing the decision for implementing Key Account Management and the implementation-process. The findings suggest that the intensity of competition as well as the intensity of coordination are factors driving companies towards the adoption of Key Account Management programs, and that companies still pay too little attention to the selection of key accounts. The study also reveals the phenomenon of ‘hidden key accounts’: More than 80% of the investigated companies without Key Account Management offer their key customers special treatment without aligning their own internal organizational structures.
