智能技术在短时间里在能源与公共事业领域取得显著优势是不争的事实.一个没有智能表计、智能电网和智能家庭解决方案的未来几乎不可想象.然而,公共事业公司在成功部署和运营智能电网的过程中,要面对很多挑战.智能电网部署不是具体的一个项目或计划,它实际上是一次业务转型,会从根本上改变公共事业公司生成数据、提供信息、制定决策、开展工作和与客户沟通的方式.了解智能电网幕后不容忽视的关键问题,是减少智能电网部署障碍的关键所在.成功部署智能电网有五大要素. 相似文献

Comparative content analysis of professional,semi-professional,and user-generated restaurant reviews
Anish A. Parikh Carl Behnke Barbera Almanza Doug Nelson Mihaela Vorvoreanu 《Journal of Foodservice Business Research》2017,20(5):497-511
This study examines the content of professional, semi-professional, and user-generated reviews. By comparing these three review types, this study was able to identify characteristics and factors unique to each type of review. Although, the amount of discourse in a particular factor varied, food is clearly the most important review factor regardless of review type. Semi-professional reviews emphasize atmosphere and décor more than both newspaper and user-generated reviews, while price factors were more prevalent in semi-professional reviews and user-generated reviews than in newspaper reviews. Understanding the varied structures of review types provides guidance for both restaurateurs and review users. 相似文献

This paper argues the case that tests of how investors value corporate social performance (CSP) based upon realised stock market returns are liable to be weak tests if markets are efficient and firms change CSP policies infrequently. We provide a theoretical explanation of why this will be the case using examples to illustrate. Subsequently, we set out an alternative theoretical framework for the purposes of investigating whether markets place a positive, or a negative, valuation on CSP, and show why this is superior to tests based upon Tobin’s Q. Using US KLD data, we demonstrate that, as theorised, markets place a positive value on CSP that is not detected by conventional returns-based tests. Our conclusion is that researchers who are interested in the question of whether engagement with a corporate social responsibility agenda is a value-enhancing activity for a company (as argued by some stakeholder theorists) or value destructive (as argued by Friedman, The social responsibility of business is to increase its profits, The New York Times Magazine, 1970), need to look beyond returns-based tests to answer the research question posed. 相似文献

The Maryland Water Quality Improvement Act of 1998 (WQIA) seeks to create environmental and other benefits to the Chesapeake Bay through reductions in nonpoint source nutrient pollution. This paper analyzes the economic impacts of the WQIA on agricultural users of nutrients (commercial fertilizers or animal manures) and on poultry growers in the state of Maryland. The net economic impacts to each of these groups are estimated along with some discussion of the distribution of the impacts. Recognition of the distribution of the impacts allows for the assessment of potential policies to address negative impacts. Additional sections of the WQIA are discussed in terms of their ability to shift the distribution of the impacts or to provide partial compensation to those most affected. The WQIA is the most restrictive agricultural nonpoint pollution control law in the US. While the WQIA only regulates nutrient use in the state of Maryland, other states, as well as the federal government, are watching how this law is implemented. Many states are considering similar laws. At the national level, the United States Department of Agriculture and the United States Environmental Protection Agency have issued draft guidelines that will control nutrients from animal operations in much the same way as the WQIA. Therefore, analyses of the economic impacts of the WQIA may be important in shaping policies in other states and at the national level. 相似文献

The detection of deception is a promising but challenging task. A systematic discussion of automated Linguistics Based Cues (LBC) to deception has rarely been touched before. The experiment studied the effectiveness of automated LBC in the context of text-based asynchronous computer mediated communication (TA-CMC). Twenty-seven cues either extracted from the prior research or created for this study were clustered into nine linguistics constructs: quantity, diversity, complexity, specificity, expressivity, informality, affect, uncertainty, and nonimmediacy. A test of the selected LBC in a simulated TA-CMC experiment showed that: (1) a systematic analysis of linguistic information could be useful in the detection of deception; (2) some existing LBC were effective as expected, while some others turned out in the opposite direction to the prediction of the prior research; and (3) some newly discovered linguistic constructs and their component LBC were helpful in differentiating deception from truth. 相似文献
