This paper presents results from the Iris Futures research project. The research was aimed at exploring the potential role of foresight in the development of the Brussels Capital Region and the identification of tools, capabilities and conditions for an improved application of foresight in Brussels. An overview was created of the characteristics of 60 future oriented activities and 120 organisations involved in such activities At the outset questions on organisational or institutional fragmentation and collaboration were not intended to be in the foreground of the research but over the course of the research this issue was observed to have a significant adverse impact on foresight capacity in Brussels. The case of the Brussels Capital Region demonstrates that institutional and organisational fragmentation need to be overcome for a futures oriented practice to have opportunity. De-fragmentation, bottom-up and institutionally, is both a condition for and an effect of the futures oriented practice underlying the foresight capacity of organisations. 相似文献

Blume and Goldstein (J Finance 52:221–244, 1997) suggest that quote competition between trading venues may diminish following tick size reductions. We test this suggestion
by studying the competitive landscape in the NYSE-listed stocks before and after decimalization. We find that NBBO (National
Best Bid and Offer) participation by non-NYSE venues declines following decimalization consistent with the prediction. At
the same time, the importance of quote competitiveness in attracting order flow increases. In addition, although not as active
in determining and maintaining the best quotes under decimals, non-NYSE venues become more active in price discovery. Finally,
decimalization leads to lower trading costs and to smaller differences in trading costs across trading venues. 相似文献

Since public networks became widespread, doubts have arisen over how to make them succeed. Scholars have traditionally addressed the issue in different ways, thus variously shedding light on the network structure, mechanisms, or managers as predictors of the network performance. The aim of our article is to explore the possibility of an interaction effect between the abovementioned factors. Our results show that there may be a relationship between network structure, mechanisms, and managers that jointly affects network performance. Therefore, important suggestions can be made about how to manage public networks successfully: (1) ensure that your network mechanisms and managerial abilities are coherent with the structure of your network; and (2) if you are in a well-established and integrated network, allow yourself some flexibility. Data were collected through a multiple case study that focused on collaboration for joint provision of home care services in Switzerland. 相似文献

This study draws from the corporate governance literature to investigate the implications of board involvement for international joint ventures (IJVs). We extend recent corporate governance research on the value of board involvement by investigating unique sources of complexity related to the nature of the IJV. We argue and find that board involvement can enhance the performance of IJVs, particularly for collaborations that are complex in nature due to their broad functional scope as well the level of market overlap between IJV parents. We complement recent research on joint venture control that has focused on the antecedents and types of control, as well as studies on formal (e.g. contractual safeguards and monitoring) and informal governance mechanisms (e.g. trust) by providing empirical evidence that IJV board involvement is valuable when directors undertake their control and coordination responsibilities. We advance corporate governance research by providing evidence that joint ventures possess several unique characteristics that shape the value of board involvement, thereby showing that applications of corporate governance theory to joint ventures are useful, but should be made with care. 相似文献

This paper explores alternative ways of evaluating and ultimately hiring a generalist consultancy for short- and medium-term projects, and how this is shaped by the size of the clients’ company. What buying factors do managers of small and large firms have in mind when hiring consultants for their projects?Instead of employing surveys incorporating predefined buying factors based on what the researchers think would be important, a cognitive mapping methodology - the repertory grid technique - is applied to investigate the underlying phenomena. Using the repertory grid technique to draw mental models is a novel research technique within the supply management field. Recent behavioral supply chain management research found the behavior of managers to be critically influenced by mental models: the lenses through which managers perceive, simplify and interpret the world.Results show differences between the buying factors used in small- and large-scale companies: managers of large companies are more ‘reputation and outcome-oriented’ and managers of small businesses are more concerned with ‘how the services are rendered’. However, both constituents stressed the importance of expertise, quality and the relationship between the client and the management consultancy, although the character of such a relationship differed between small- and large-scale firms. Results also point out criteria that managers of small and large companies employ to discriminate between good and poor performing consultancies and to judge service delivery. The practical implications for both companies hiring consultancies and the consultancy companies are discussed. For consultancies, our findings can help tailoring their efforts to a differing clientele when marketing and selling their services. For companies hiring consultancies, fixating too much on particular buying factors may lead to biased decisions. 相似文献

A bilinear multivariate errors-in-variables model is considered. It corresponds to an overdetermined set of linear equations
AXB=C, A∈ℝm×n, B∈ℝp×q, in which the data A, B, C are perturbed by errors. The total least squares estimator is inconsistent in this case.
An adjusted least squares estimator is constructed, which converges to the true value X, as m →∞, q →∞. A small sample modification of the estimator is presented,
which is more stable for small m and q and is asymptotically equivalent to the adjusted least squares estimator. The theoretical
results are confirmed by a simulation study.

ABSTRACTThis paper proposes a hybrid collaboration recommendation method that accounts for research similarities and the previous research cooperation network. Research cooperation is measured by combining the collaboration time and the number of co-authors who already collaborated with at least one scientist. Research similarity is based on authors’ previous publications and academic events they attended. A weighted directed graph is built to discover new collaborators by using direct and indirect connections between scientists. Moreover, a consensus-based system is built to integrate bibliography data from different sources. The experimental results show that our method improves the recommendation performances over other methods. 相似文献

In this paper, we consider an environment where individual actions have externalities and two types of agents exist: agents with social preferences (the good) and selfish agents. Selfish agents have pay‐off functions that do not take into account social welfare. The pay‐off of an agent is a linear combination of social welfare and the pay‐off of a selfish agent. We demonstrate that the corrective tax rates that maximize social welfare do not depend on the degree of social preferences. Hence, the good and the selfish should not be taxed differently. 相似文献

E-commerce is increasingly influencing business operations, as a major supportive medium for different strategies or as a strategy on its own. This paper seeks to identify impacts from concomitant changes on the development of cities. To this purpose, emerging time-based strategies are analysed in manufacturing and customer-services strategies are analysed in the services sector. The focus of the study is on proximity needs and what these needs imply for elimination of physical segments from value chains and insertion of virtual segments into these chains. The findings are then linked with trends for agglomeration or spread of urban activity. The conclusion is that the future of cities is far from clear. Trends for agglomeration go hand in hand with trends for spread on different spatial levels. In addition, there are huge knowledge gaps. The paper concludes with suggestions for further research to fill these gaps. 相似文献
