We study the conditions for the emergence of cooperation in a spatial common-pool resource (CPR) game. We consider three types
of agents: cooperators, defectors and enforcers. The role of enforcers is to punish defectors for overharvesting the resource.
Agents are located on a circle and they only observe the actions of their two nearest neighbors. Their payoffs are determined
by both local and global interactions and they modify their actions by imitating the strategy in their neighborhood with the
highest average payoffs on average. Using theoretical and numerical analysis, we find a large diversity of equilibria to be
the outcome of the game. In particular, we find conditions for the occurrence of equilibria in which the three strategies
coexist. We also derive the stability of these equilibria. Finally, we show that introducing resource dynamics in the system
favors the occurrence of cooperative equilibria.

This paper assesses the impact of regulatory and environmental factors and statistical noise on the efficiency of public transit
systems within a DEA-based framework. Using a panel of Italian companies, we implement a DEA-SFA mixed approach based on [H.O.
Fried et al. (2002) Journal of Productivity Analysis, 17(1–2), 157–174] to decompose DEA inefficiency measures into three components: exogenous effects, managerial inefficiency and
stochastic events. Besides providing evidence on the determinants of input-specific efficiency differentials across companies,
the results point out that managerial skills play a minor role, and emphasize the relevance of regulatory policies aimed at
replacing cost-plus subsidization with high-powered incentive contracts as well as improving environmental conditions of public
transit networks.

Countries and companies use foresight studies to manage uncertainty. Environmental scanning and trend analyses are important tools for identifying and monitoring change. Trend analysis requires more than simply extrapolating to the future. The content of communication serves as the basis of inference so those trends could be explored.This research uses an interdisciplinary approach combining media content analysis and factor analysis to discover many ways Turkey and the world may restructure and what the new society may look like as perceived by the individuals who participated in the survey. It determines six types of individuals in Turkey with different personal attitudes towards megatrends. Similarities and dissimilarities with previous studies in Austria and Germany are identified and discussed. 相似文献

Designing information systems (ISs) requires a thorough understanding of the organizational knowledge processes in which these systems are used. Although much is known about internal organizational knowledge processes, the understanding of external knowledge processes is less developed. Hence, this paper reflects an attempt to operationalize and test a model of the process of external knowledge integration (EKI), consisting of an identification, acquisition, and utilization stage. We utilize high-technology based firms from a variety of high-tech categories including nanotechnology based firms since these firms have critical knowledge integration needs. The results of an international survey, with responses of 317 high-tech companies, suggest that not these three EKI-stages, but four organizational effectiveness functions (goal attainment, pattern maintenance, adaptation, and integration) account for most variation in responses. These findings seem to imply that ISs that are to support the EKI-process should be designed according to organizational effectiveness functions rather than to EKI-stages. It is proposed that each organizational effectiveness function imposes different requirements on ISs because users interact differently with IS in each function. 相似文献

Internet Protocol Television (IPTV), the convergence services of television and Internet, is being rapidly developed around the world. The advent of digital technologies has changed the convergence market dramatically with the wide diffusion of the convergent services. Using the Technology Acceptance Model as a conceptual framework and method of logistic regression, this research analyzes the demand for IPTV by drawing data from 452 consumers. Individuals' responses to questions about whether they accept IPTV are collected and combined with observations of their socio-economic status and intrinsic/extrinsic factors modified from the Technology Acceptance Model. Results of logistic regression show two variables (intrinsic and extrinsic factors) that seem to explain what influences consumer behavior towards adopting IPTV. Overall, the logistic regression model explains over 50% of the variance in the IPTV adoption. The variances shed light on the multi-open platform environment that IPTV will forge. 相似文献
