Research in Motion's (RIM's) entry into the Chinese market during a time when many distractions —principally a patent dispute with NTP—occupied management's attention was not a foregone conclusion. China remained a difficult market to crack. One holdup was an impasse with regard to RIM's use of encryption technology and the Chinese authorities' desire to monitor e‐mail traffic and content. Here the technical and political concerns were entangled. To further complicate things, the entirety of RIM had until recently been preoccupied with the legal settlement with NTP in the United States. Issues in this study highlight real‐world dilemmas in a thriving firm. The founders are still in charge, and new markets present themselves regularly. A very real challenge is divided attentions. The standstill over market entry calls for integrative thinking—bringing together disparate and contradictory elements for resolution. RIM's way out will invariably involve embracing complex relationships in order to find a resolution to the various conflicting institutional forces. © 2008 Wiley Periodicals, Inc. 相似文献

From Industrial to Innovation Policy 总被引:2,自引:0,他引:2
Luc Soete 《Journal of Industry, Competition and Trade》2007,7(3-4):273-284
Industrial policy has been a cornerstone of economic policy in Europe after the world war and the transformation of basic industries like coal and steel were key issues at the beginning of European integration. In the 1970s and 1990s industrial policy shifted toward support of high-tech industries. In the seventies the importance of a more systemic view came up, policy had to address the specific weaknesses of the innovation system. The Lisbon agenda finally combines competitiveness with social and environmental goals. Industry plays an important role in generating welfare and industrial policy is in different forms and sorts back, high on the agenda. 相似文献

Attempts to explore empirically the link between HRM and firm performance are numerous. Yet, research on this link remains
restricted to large companies. Little is known about the extent to which the existing results extend to small businesses.
The purpose of the present study is to develop and test a conceptual framework linking HRM to financial performance that fits
small businesses. The central question is whether the development of an intensive HRM is profitable for smaller organizations.
For the development and optimization of the conceptual framework, we rely on human capital theory and bankruptcy prediction
models. Using structural equation modeling, we study the mediating effect of voluntary turnover and productivity on the relationship
between HRM intensity and one year lagged financial performance. The results show both productivity and profitability enhancing
effects as well as a cost increasing impact of HRM intensity. 相似文献

This paper proposes to give a toll to help decision makers in critical situations. The principle of our research is based on a modelling approach for Cooperative Knowledge Based Systems. This approach is based on a Task/Method paradigm that we describe. We then propose to take into account collateral effects of tasks in order to support decision makers in a critical context. The proposed tool can then generate a degraded solution for which, collateral effects of previous tasks have been taken as new goals to reach. This study is possible thanks to the definition of several kinds of models: a Good Functioning Model and a Degraded Tasks Library. 相似文献

Sengupta and Sengupta (“Viable Proposals,”International Economic Review 35 (1994), 347–59.) consider a payoff vector of a TU‐game as a viable proposal if it challenges each legitimate contender. They show that for each game the set of viable proposals is nonempty. Their proof, however, has a flaw. I present a proof based upon a result by Kalai and Schmeidler (“An Admissible Set Occurring in Various Bargaining Situations,”Journal of Economic Theory 14 (1977), 402–11) . 相似文献

Testing the Empirical Relationship between Best Management Practice Adoption and Farm Profitability 总被引:1,自引:0,他引:1
Luc Valentin Daniel J. Bernardo Terry L. Kastens 《Review of Agricultural Economics》2004,26(4):489-504
Several "best management practices" (BMPs) aimed at reducing movement of nutrients, pesticides, and sediment into surface water resources have been developed and promoted by Extension and other agencies over the past several years. This study utilizes actual farm-level economic and BMP adoption data to rigorously analyze the relationship between BMP use and farm profitability. Results indicate that adoption of nutrient BMPs has a significant positive effect on net farm income (NFI) for wheat and corn, while herbicide BMP adoption, particularly use of BMPs related to the application of atrazine on corn, has a small (but statistically significant) negative impact on income. Adoption of soil conservation BMPs is not shown to have a statistically significant impact on farm income. 相似文献

International comparisons indicate that, on average, Belgian companies spend less on training than their French, German and Dutch counterparts. Encouraging companies to commit to training has consequently been an important policy goal over the last few years. One notable aspect of the policy to encourage training efforts by companies is that the effort is always represented in terms of the resources invested (input), not in terms of the learning achieved (output) or the quality of training programmes (throughput). Government policy is aimed at increasing the level of investment in company training. One of the questions we wish to investigate is whether this input-oriented approach to the training issue is actually effective. Whether companies will succeed in raising human capital to ever-increasing levels may depend not only (and maybe not even chiefly) on the extent of financial investment in training. The investment level does not necessarily determine the quality of the training processes developed by companies. Therefore, this paper focuses on the following research questions: (1) to what extent do companies monitor the systematic development of sufficiently effective training processes? In other words, is qualitative under-investment an issue, alongside financial under-investment? (2) Is the level of financial investment in company training correlated to the quality of training processes? The empirical data confirm that a kind of 'qualitative' under-investment can be reported and that the relationship between the level of investment in training and the quality of the training programmes is weak. 相似文献

We model the dynamic volatility and correlation structure of electricity futures of the European Energy Exchange index. We use a new multiplicative dynamic conditional correlation (mDCC) model to separate long‐run from short‐run components. We allow for smooth changes in the unconditional volatilities and correlations through a multiplicative component that we estimate nonparametrically. For the short‐run dynamics, we use a GJR‐GARCH model for the conditional variances and augmented DCC models for the conditional correlations. We also introduce exogenous variables to account for congestion and delivery date effects in short‐term conditional variances. We find different correlation dynamics for long‐ and short‐term contracts and the new model achieves higher forecasting performance compared to a standard DCC model.

The majority of South Africans living in rural areas are food insecure despite high levels of national food self-sufficiency. The household food security position of two groups of rural farming households in the Venda region was evaluated quantitatively: one group produces vegetables that are sold or consumed locally, the other group produces cash crops – mangoes and other subtropical fruits. Using the collected data, food availability and energy, protein and fat requirements were calculated and balances derived. It was found that more than 80 per cent of the households had a negative balance of energy, protein and fat intake. The average energy, protein and fat coverage consumption was the same for both groups of farmers. A number of agricultural determinants were tested, but only non-agricultural determinants were found to be significant. These include household size, household (food) expenditure and proportion of the budget spent on food. 相似文献
