Sustainable land use planning is crucial for realizing the aim of food security and for combating land degradation in the Sahel. A participatory land use planning workshop was organised in a village in the eastern region of Burkina Faso to investigate land use problems, their causes, effects and possible solutions. Participatory research tools and GIS were combined to get insight into possible conflicts or synergies between different land use options as mapped by different ethnic groups. Pictograms were used to locate alternative land use options on the map, after which they were digitised for analysis with GIS. The workshop confirms the importance of integrating scientific and local knowledge to develop concrete options for sustainable land use that fit to local realities and aspirations. Local people are knowledgeable about the driving forces behind land degradation, they take actions to combat the effects of degradation, and they have concrete ideas about alternative land use options. The use of GIS proved its added value in the participatory process of integrated land use planning. The maps that were produced also facilitate discussions between community members, researchers and government representatives at the regional level, both regarding current land use problems and regarding alternative options as perceived by the local population.  相似文献

In this introductory paper, we first discuss the emergence of global sourcing of business services and how these have been largely ignored in the IB field. Offshoring of business services has reached substantial proportions. Despite the radical growth, IB research on global sourcing is still in its infancy. Offshoring of business services represents a new type of internationalization. The offshoring of high-value services confronts companies with many of the challenges that are typical of an internationalization process in which well-known models and concepts of internationalization are applicable but also leave important unanswered questions requiring reconsideration and revision of these theoretical positions. Offshoring of business services is fundamentally different from outsourcing offshore of manufacturing activities. Using data from the Offshore Research Network (ORN), we track patterns of the emergence and diffusion of global sourcing of business services. On the basis of these new insights, we make a plea for a more encompassing, co-evolutionary perspective of global sourcing stressing the interactions between managerial intentionality, path-dependent experience and knowledge accumulation, as well as the institutional and selection forces. In particular, we develop a co-evolutionary offshore decision model integrating managerial intentionality, knowledge/experience and institutional and selection forces that explain the heterogeneous outcomes of offshoring. Although emergent outcomes of co-evolutionary dynamics are highly idiosyncratic, we identify in this paper some underlying mechanism that drive specific global sourcing patterns. Finally, we position the papers of this special issue in this co-evolutionary model.  相似文献

A new field of research centered on the offshoring of white-collar tasks is opening. We analyze the choice of governance mode for international offshoring activities based on a four-fold framework that integrates multiple theoretical perspectives. Firms choose between an internal or external mode based on their institutional environment, the offshoring behavior of similar firms in their reference group, firm-specific characteristics and objectives, and the particular setting of specific implementations. We test our relationships using detailed data on offshoring activities of US and German firms. Based on the outcomes we conclude that each dimension of the chosen framework is needed to explain the governance mode decisions of firms and this overarching framework may also be applicable to other topics in internationalization research.  相似文献

Strategy researchers have argued that heterogeneity in firms' practices and profitability within and across industries may derive from industry‐level differences in the extent of interdependencies among firms' activities. Theoretical models have clarified how and why differences in the extent of the interdependencies faced by firms across industries may affect the distributions of firm profits, but the specific predictions from these models have not been empirically tested. In this paper, we present what we believe is the first large scale empirical analysis linking differences in the extent of interdependencies across industries to differences in the distribution of firm profits within and across those industries. We use survey data to measure interdependencies systematically across a wide number of industries, thus addressing the primary obstacle to incorporating interdependencies in larger scale empirical work, and find evidence consistent with the theoretical predictions: average profitability is highest in industries with moderate levels of interdependency; the dispersion of profits among firms is higher in industries with more extensive interdependencies; and industries with more extensive interdependencies have a more positively skewed performance distribution. We find that the effect of interdependencies on average industry profitability is similar in scale to the effect of patent protection and industry growth rates, placing interdependency squarely among the strategy field's central concepts.

New Compensation Standard for Land Expropriation in China   总被引:1,自引:0,他引:1  
This paper explores a new compensation standard for use in agricultural land conversion in China during the land‐expropriation process, based on the market value definition. Assuming identical bargaining power between the buyer and the seller, efficient and equitable compensation is obtained through a market transaction and bargaining negotiation mechanism, under the assumpation of a perfect market. From the state‐of‐the‐art viewpoint of land appraising, a practical approximation of the theoretical optimal compensation will provide an effective solution for China, under the current collective‐owned land property rights structure.  相似文献

Drawing on the goal theory to effectiveness, the current research study attempts to identify performance measures of small ventures by focusing on the tourism industry and by doing so develops a conceptual model of small-venture performance in a service industry within its unique conditions. After reviewing theory and research on small venture performance measures in general and in service industries in particular, we propose that performance measures of small tourism ventures constitute a combination of short- and long-term measures. Furthermore, both types of measures include both objective and subjective dimensions. The findings, based on a cluster sample of 305 small tourism venture owner–managers that were interviewed face to face, generally supported the research proposition. The study emphasizes the importance of mapping the venture's achievements, allocating resources, and developing managerial skills to improve its performance and ability to survive in the long run.  相似文献

This study investigates the scope of an audit conducted during the first part of the annual auditing cycle. It measures empirically the probability of auditing various balance sheet and income statement accounts. The results indicate that current assets and liabilities have a higher probability for an interim audit than fixed assets, long-term debt and equity accounts. Furthermore, the likelihood of including each account in an interim audit increases with client size, so the larger an auditee, the wider the audit scope during the beginning of the audit cycle. Also, the empirical results indicate that the lower the familiarity of the auditor with the auditee, the wider the scope of an interim audit. These results seem to be consistent with auditing theory and intuition.  相似文献

A simple trading model is presented in which Bayes’ rule is used to aggregate traders’ forecasts about risky assets’ future returns. In this financial market, Bayes’ rule operates like an omnipotent market-maker performing functions that in 1776 Adam Smith attributed to an “invisible hand.” We have analyzed two distinct cases: in the first scenario, the traders’ forecast errors are uncorrelated, and in the second scenario, the traders’ forecast errors are correlated. The contribution of our paper is fourfold: first, we prove that the “efficient market” mean-return can be expressed as a complex linear combination of the traders’ forecasts. The weights depend on the forecast variances, as well as on the correlations among the traders’ forecasts. Second we show that the “efficient” variance is equal to the inverse of the sum of the traders’ precision errors, and is also related to the correlations among the traders’ forecast errors. Third, we prove that the efficient market return is the best linear minimum variance estimator (BLMVE) of the security’s mean return (in the sense that it minimizes the sum of the traders’ mean squared forecast errors). Thus, an efficient market aggregates traders’ heterogeneous information in an optimal way. Fourth, we prove that an efficient market produces a mean return (price) as a Blackwell sufficient (most informative) experiment among all possible aggregated expected return (price) forecasts.  相似文献

The Phaistos Disk is an ancient artifact from Crete. At each side of the disk, a series of unknown signs is written along a spiral. Professional archaeologists expect that we will only learn what it is until similar objects are found. A statistical analysis in this article shows what it is not: it is not a one‐dimensional text, since there are relations between the signs in adjacent windings of the spiral. Three patterns of such relations have been identified. A Monte Carlo simulation of one of them has been performed, using a model of the spiral form. It is concluded that the probability of this pattern being coincidental is small, well below the conventional threshold.  相似文献
