I have argued that for the period from 1661 to 1850, patent data in England were consistent in that no official changes in methods and standards of issuance occurred. Book data on titles published on farming production methods were similarly consistent from 1523 to the mid-19th century because the market for books developed gradually and the technology of printing was not substantially changed until the mid-19th century.My main point is that data on output of titles of books on farming productive techniques in England are useful measures of technological change. Books did have information on good production methods and could express productive ideas where a patent may not be issued. Further, the literacy rate of farmers was high so that books were likely an important source of ideas on farming production methods. Finally, the fluctuations in the book data were highly related to the fluctuations in the patent data, suggesting that a common set of factors caused those fluctuations. The high correlations between the detrended book and patent data indicate that if we accept patenting as a useful measure of technology we may also accept book title output of a technical nature as a good measure of technical change.I used the data for a simple analysis of the trend growth rate of agricultural technology in England from 1551 to 1850. While there is limited evidence to show that the subperiod 1651–1750 saw a slowing in the trend of development of farming technology, I argue that a division of the entire period into subperiods is too simplistic. A more fruitful approach would be an analysis of the underlying forces that determined the trend of development of the technology of English agriculture.The next step is an analysis of the forces that influenced technological development of English farming. From an economic point of view, market forces play an important role in influencing technology. Because such an analysis deserves careful consideration, I leave that to another paper (see Sullivan and Simon, 1983).  相似文献

Market Effects of Recognition and Disclosure   总被引:1,自引:0,他引:1  
Our recognition and disclosure model reveals that price informativeness is determined by the interaction of the qualities of three information sources—the recognized amount, the disclosed information, and the information revealed by price—and accounting expertise acquisition. It also reveals that recognition of an accounting amount alters each of these, thereby affecting price informativeness. Perhaps surprisingly, we find that recognition of a highly unreliable accounting amount, rather than simply disclosing it, can result in greater price informativeness. Likewise, recognition of a highly reliable amount can result in lower price informativeness. Our findings suggest that, because of the effects of aggregation, basing recognition decisions on reliability alone is too simplistic. Reliability relative to relevance is key, not reliability per se. We also find that recognition and disclosure affect the coefficients in a regression of price on accounting amounts.  相似文献

This paper assesses the current status and future prospects for bioregional planning in the Southern Appalachian Man and the Biosphere (SAMAB) region in the United States. The SAMAB region is one of the most biodiverse temperate regions in the world. The region's environment is threatened by development, air and water pollution, and invasive species. Numerous institutions in the region have some responsibility for protecting the region's environment, including the National Park Service, the US Forest Service, the US Environmental Protection Agency, the US Fish and Wildlife Service, several states, hundreds of municipalities, and numerous active non-profit organizations. Twenty-seven people associated with bioregional planning were interviewed to gauge their opinions on the state of bioregional planning in the SAMAB region. Overall, the respondents do not believe that the totality of all those efforts comprises bioregional planning because the efforts are limited in scale and scope and somewhat uncoordinated. With respect to the future of the region, the respondents found it difficult to imagine the state of the region 50 and especially 200 years into the future. Additionally, almost all of their definitions of bioregional planning included a spatial dimension but none included a time dimension. Thus, one of our conclusions is that the future of bioregional planning in the region will be hampered by difficulties people responsible for environmental protection have in dealing with ‘the future’. Much effort needs to be expended to inculcate people in the region with the desire to anticipate problems long before they occur. Reactive responses, which characterize the majority of current efforts, are likely to be ‘too little, too late’.  相似文献

Careers in public sector science: orientations and implications   总被引:1,自引:0,他引:1  
There is consensus that the world of science is changing (Ziman, 1994; see for example Nowotny et al., 2002). The environment in which scientists work is typified now as increasingly dynamic, managerialist and commercialised. This paper focuses on how scientists within different organisational and national contexts understand and enact their careers in the face of such changes. Based on empirical work in the UK and New Zealand, this paper introduces four career orientations evident in the career accounts of these participants. The categories are further analysed in terms of the key drivers to career: science, the organisation and the individual. Implications for career management are discussed in each section. In conclusion, the paper makes two related contributions. First, the evidence presented poses a challenge to highly individualised notions of the career actor central to current career thinking, instead revealing scientists' continued attachment to old institutional arrangements alongside new and emerging ways of understanding career. Second, with reference to the issue of career management of research scientists, the study highlights the need for those involved in management to look beyond employing organisations to other life interests, and science itself. It argues the need for those involved in career management to recognise the variety of legitimate ways to run a scientific career.  相似文献

Research offers insights that, if heeded and built upon, could improve financial reporting, thereby contributing to a more prosperous society. In particular, research suggests improvement could stem from greater use of fair value; a performance statement designed to reveal the information embedded in changes in fair value; better information to help investors assess the value of intangible assets; more specific information about risk and uncertainty; information that is unbiased, rather than conservative; acceptance of a degree of earnings management together with a determination of how much earnings management is acceptable; and a financial reporting package designed to convey information users need, which presumably is broader than today's financial statements.  相似文献

We perform peridogram based cycle analysis of firm capital structure and find evidence that firms’ leverage is both persistent and cyclical. The cyclicality of leverage is supported by the trade-off, pecking order and market timing capital structure theories (Korajczyk and Levy in J Financ Econ 68:75–109, 2003; Bhamra et al. in Rev Financ Stud 23:645–703, 2010). Although market timing theory research supports persistence, previous literature dictates that the trade-off and pecking order theories may predict either persistent or mean reverting leverage. Our tests reject mean reversion in favor of persistent and cyclical leverage. We corroborate pecking order theory literature that predicts leverage is persistent. In these models, when firms’ investment spending is below earnings, leverage decreases. In addition, we examine whether firms change their capital structure as a result of business and financial cycles. Since financial cycles last longer than business cycles, financial cycles should have a long term effect on leverage. Our findings confirm the persistent leverage business cycle models that suggest firms change their capital structure due to financial and credit cycles (Jermann and Quadrini in Am Econ Rev 102:238–271, 2012; Azariadis et al. in Rev Econ Stud 83:1364–1405, 2016). We conclude that leverage is persistent due to the cyclicality of the financing decision.  相似文献

Despite the increased use of seasonal employees by organizations, few studies have been completed on the attitudes and service quality of seasonal office workers. Using Lautsch's classification model, we analyzed the organizational context in which the standard and seasonal workers in this study were employed. Hypotheses were developed based upon the organizational analysis and social exchange theory. Results from archival data obtained from a web‐based organizational survey of 205 clerical and professional workers indicated contrary to expectations, standard and seasonal employees did not significantly differ in terms of perceptions of overall job conditions, perceived organizational support (POS), or job engagement. However, seasonal employees did report significantly fewer opportunities to work on challenging tasks, less comfortable physical working conditions, and less job security than the standard workers. As predicted, standard employees reported significantly higher levels of service quality performance than seasonal employees. Additionally, job engagement mediated the relationship between POS and service quality for both the standard and seasonal employees. Implications for managing seasonal employees are discussed.  相似文献

As the reach of global business operations increases, cultural context will likely influence the nature and amount of sexual harassment workers experience. Surprisingly, little is known about sexual harassment in Russia, an attractive target for expanding companies. To address this gap in the literature, we examine Russian workers’ perceptions of sexual harassment severity through the lens of cultural context. In particular, we examine the sexual harassment severity perceptions from the perspective of both targets and perpetrators. Results indicate that as targets of sexual harassment, Russian women and men held similar sexual harassment severity perceptions. However, as perpetrators, Russian women reported perceiving the harassment they committed as being less severe than the reports of Russian men. Further, among both targets and perpetrators, Russian women held less permissive sexual attitudes than Russian men, with this difference mediating the relationship between participant sex and perceived sexual harassment severity: women perceived greater severity than men because women hold less permissive sexual attitudes. Implications for research, practice, and the role of national culture in shaping the social construction of sexual harassment are discussed.  相似文献

Odds are generally defined as the number of successes divided by the number of failures in a given number of trials. An odds ratio is the ratio of one odds divided by another. Odds ratios can be adjusted to reflect associations with the outcome independently of the influence of associations with other variables. These are adjusted odds ratios. There are several well known methods for comparing odds ratios and testing for statistically significant differences between them. Analogous methods for adjusted odds ratios are not well known or well documented. One method for comparing adjusted odds ratios is explained by Hosmer and Lemeshow (Applied logistic regression, 2000). This method is used for the odds ratios for two variables from the same data set. The purpose of this analysis was to apply this method to a different situation: comparing odds ratios for the same variable from two different data sets. Monte Carlo trials were used to assess the performance of the method and these indicated the method performed well.  相似文献

This study examines market challenges facing a local agriculture industry in a small island setting. Examination of the Hawai‘i local avocado industry indicates labeling can address the product information gap between consumers and producers, improve market share, and increase import substitution by local products. Currently, local avocados occupy only 33% of market share, compared with 67% captured by imports. Consumer preferences among local labeled, local unlabeled, and imported avocados were analyzed using multinomial logistic regression. Statistical results showed that labels influence consumers’ decisions to buy local or imported avocados, and their preferences were also influenced by sociodemographic variables, avocado characteristics, and purchasing behavior. Key market segments to target and policy implications are also discussed.  相似文献
