We explore the possibilities of the Internet as a tool for supplying information necessary for the organization and mobilization of successful opposition movements, especially under non-democratic regimes. Examples of the roles the Internet plays in the political processes in Russia are discussed in detail. In particular, the recent cyberprotest cases of the Ingushetiya.ru website and the movement to release political prisoner Svetlana Bakhmina are investigated. Besides showing the Internet's significant role in organizing modern protests, these cases also demonstrate that in environments where practically all traditional mass-media are under the authorities' control, the Internet becomes the major source of alternative information. Our paper offers a look at how deploying technologies can bring about social change, even in some of the most difficult political environments.  相似文献

China has attracted worldwide attention due to the global economic and environmental effects of its rapid economic growth over the last 20 years, with particular attention given to the country's accelerating energy consumption and resulting greenhouse gas emissions. China's electricity sector is particularly important for both of these issues as it accounts for nearly half of its greenhouse gas emissions and even greater proportions of the country's demands for primary fuel resources. In order to better understand how these issues may progress in an economy changing as fast as China's, this paper develops a framework that can be used to help model the electricity sector's future development. The framework builds upon key technological and socio-economic drivers, including those affecting electricity demand (e.g., economic growth, structure, energy efficiency, urbanization, and change in per capita income) and electricity supply (e.g., deregulation, initiatives to promote natural gas, nuclear and renewable energy, air pollution regulations, price developments for coal and natural gas, and changes in generation technology). The framework serves as a foundation for a scenario exercise on the greenhouse gas and fuel consumption impacts of different developmental paths for China's electricity sector. These scenarios and their implications for emissions and fuel consumption are presented in a subsequent article.  相似文献

Increased public access to environmental information contributes to a greater awareness of environmental matters. However, there is no specific structure of public Environmental Information Systems (EIS) for institutions and other social partners to accomplish this goal. Multimedia has been largely used in EIS. Mobile services may play a new role within communicating multimedia environmental information in a citizenship framework. Furthermore, the use of mobile services may promote the development of Mobile Information Society (MIS). Hence, there are currently plenty of technologies to adopt in order to reach the public. This paper is focused on exploring whether Multimedia Mobile Services (MMS) can contribute to augmenting public environmental awareness. A platform of common mobile devices was successfully used to test mobile public access to environmental information in Portugal. This enabled the exploration of real environmental services in mobile contexts. Furthermore, an advanced interactive prototype was developed indoors to simulate a Location-Based Service (LBS) applied to coastal zones. Recommendations for future work are presented.  相似文献

In this paper we review methods that aim to aid the anticipation of rare, high-impact, events. We evaluate these methods according to their ability to yield well-calibrated probabilities or point forecasts for such events. We first identify six factors that can lead to poor calibration and then examine how successful the methods are in mitigating these factors. We demonstrate that all the extant forecasting methods — including the use of expert judgment, statistical forecasting, Delphi and prediction markets — contain fundamental weaknesses. We contrast these methods with a non-forecasting method that is intended to aid planning for the future — scenario planning. We conclude that all the methods are problematic for aiding the anticipation of rare events and that the only remedies are to either (i) to provide protection for the organization against the occurrence of negatively-valenced events whilst allowing the organization to benefit from the occurrence of positively-valenced events, or (ii) to provide conditions to challenge one's own thinking — and hence improve anticipation. We outline how components of devil's advocacy and dialectical inquiry can be combined with Delphi and scenario planning to enhance anticipation of rare events.  相似文献

To further understand the effectiveness of experience curves to forecast technology costs, a statistical analysis using historical data is carried out. Three hypotheses are tested using available datasets that together shed light on the historical ability of experience curves to forecast technology costs. The results indicate that the Single Factor Experience Curve is a useful forecasting model when errors are viewed in their log format. Practitioners should note that due to the convexity of the log curve a mean overestimation of potential cost reductions can arise as values are converted into monetary units. Time is also tested as an explanatory variable, however forecasts made with endogenous learning based on cumulative capacity as used in traditional experience curves are shown to be vastly superior. Furthermore the effectiveness of increasing weights for more recent data is tested using Weighted Least Squares with exponentially increasing weights. This results in forecasts that are less biased, though have increased spread when compared to Ordinary Least Squares.  相似文献

Why does diffusion of innovation sometimes propagate throughout the whole population, and why at other times does it halt in its interim process? The current paper provides a potential answer to this question by developing a simple computational model of social networks. The proposed computational approach incorporating small-world graphs enables the authors to find that diffusion of innovation is more likely to fail in a random network than in a highly clustered network of consumers. A marketing implication is that the choice of initial target groups and their network structures matter in influencing whether an innovation makes full or partial penetration, in markets where network effects plays a role.  相似文献

Managers form mental models of their business environment, and make strategic decisions based on these perceptions of reality. We study managerial perceptions of the competitive advantage gained by a pioneering firm. We expect that managers will make pioneering entry decisions based on their perceptions of pioneering advantages. Due to cross-national cultural and business environment differences, managers from different countries will employ different mental models and thus perceive the relative advantage of pioneering differently.Drawing from the literature on cultural influence on decision-making, we build a theoretical framework of perceived pioneering advantage in different cultural environments. From this framework, and from cultural differences that exist between the United States and South Korea, we derive hypotheses regarding expected cross-cultural perceptual differences. We test these hypotheses using samples of senior product managers from both countries. We find that some, but not all, of the principles of pioneering advantage empirically verified in North America are generalizable to the culturally-different South Korean business environment.  相似文献

Strategic foresight requires a longer and broader view of the environment and, as we at the Institute for Alternative Futures (IAF) would argue, a conscious attention to the organization's vision and visionary scenarios in the environment. Having promoted foresight on six continents for a wide range of governments, corporations, and non-profit organizations, we have developed lessons on the design and set-up of foresight efforts, their use and follow-through. Lessons include: Scenarios using ‘aspirational futures’ should include expectable, challenging, and visionary alternatives; beware of and understand ‘allergic reactions’ to foresight given some individuals', particularly leaders', psychological preferences; foresight is most effectively done by and for top leadership but foresight for units or regions of the organization can also be successful; to get the most value, it is important to err on the side of boldness and vision in developing scenarios; foresight efforts create a ‘safe space’ for exploring challenging situations; associations as collections of companies or professionals have unique foresight needs including elected leadership that rotates every year, and the need to communicate the results of foresight efforts to their members effectively; government and corporations have more similarities than differences in foresight, but companies have more resources and can move quickly to develop and use the foresight.  相似文献

When the value of a product or service is uncertain, outcomes can be inefficient. A market for evaluations can theoretically increase efficiency by voluntarily eliciting an evaluation that would otherwise not be provided. This paper uses a controlled laboratory experiment to test the performance of four market mechanisms to provide product evaluations. The mechanisms considered are derived from the oft studied uniform price sealed bid, discriminatory price sealed bid, English clock auction, and Dutch clock auction. Our results indicate for this nonrivalrous product that (i) each of these institutions improves social welfare and (ii) the performances of the four mechanisms are equivalent. This second point is particularly noteworthy given that differing behavior is routinely observed in traditional private value auctions.  相似文献
