Interest in paid work performed in the home increasingly focuses on the concept of telework but debate over definitions continues. This paper discusses aspects of this debate and argues that project-specific definitions are useful and inevitable. The assertion that a single definition should be used by all research in this area is challenged.  相似文献

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

Water's role in manufacturing technologies has received limited attention. A KLEM model of the sector's technology is extended to include two facets of water use: intake and recirculation. Three annual cross-sectional surveys on plant-level water use are pooled and combined with census data to estimate this extended model for the Canadian manufacturing sector over the period 1981–1991. While Canada's water allocation regulations influence private water withdrawals, statistical tests support representing water intake as a variable input. Water intake is found to be a substitute for water recirculation, energy, labour and capital. The relationship between water intake and recirculation is stronger when water intake is process-related rather than related to cooling and steam production. Technological change has been biased in the direction of increased water intake and decreased water recirculation.  相似文献

Small businesses are the backbone of the economy in many countries. In Europe, for example, small companies represent more than 90 per cent of all companies (e.g., Lukacs, 2005 ). Although these companies represent such an important portion of the economy, few studies have examined their voluntary disclosure decisions. Because small companies have certain unique characteristics compared with their larger counterparts, the general applicability of past voluntary disclosure studies to small companies is questionable. Drawing on agency and proprietary cost theory, this study investigates whether ownership, competition, and accountant factors influence the decision to disclose financially sensitive information on a voluntary basis. Our results (using an e‐mail questionnaire to small private companies in Belgium, n = 1,068) indicate that nearly 40 per cent of the responding companies are not aware of their disclosure behavior. For companies that are aware of their disclosure behavior, the logistic regression analysis demonstrates that factors relating to the separation of ownership and control, namely the type of ownership and number of shareholders, are among the most important determinants in the voluntary disclosure decision of small private companies. Companies with at least one legal entity as an owner of a company are less likely to disclose, while companies with more shareholders are more likely to disclose. We also provide evidence that perceived competition and the default setting of the accounting software used have a significant influence on the voluntary disclosure behavior.  相似文献

For the circular economy to be tenable, consumers need to not only return products after use, but also purchase products that are remanufactured. However, research finds that consumers have a poor opinion of remanufactured products and are typically not prepared to adopt them. Thus, development of the circular economy is dependent upon deeper understanding of consumers’ attitudes and behaviors. Research typically considers either micro‐level or macro‐level factors when assessing consumer perceptions of remanufactured products. The current research incorporates macro‐level factors of price, government incentives and environmental benefits with the moderating influence of micro‐level consumer attitudes to examine consumers’ intention to switch from purchasing new products to remanufactured products. The findings suggest that a consumer's attitude toward remanufactured products is an important moderating factor predicting consumer switching behavior to remanufactured products.

The terms Attention Deficit Disorder (ADD) or Attention Deficit/Hyperactivity Disorder (AD/HD) refer to a neurological impairment that affects the individual's ability to sustain attention and to behave in a calm, rational manner.3Although this disorder has long been considered to be restricted to childhood, recent research has demonstrated that many children carry it over into adult life and take it with them into the workplace. Most U.S. courts have treated AD/HD as a disability covered by the Americans with Disabilities Act (ADA).4However, in the summer of 1999, the U.S. Supreme Court made three decisions that will undoubtedly affect the future status of AD/HD and other impairments under the ADA. This article examines those decisions, how they affect the employment rights of AD/HD-afflicted employees, and the changes they will probably bring to litigation in this area. Because we have many reservations about the court's decisions, we not only voice our criticisms of the decisions, but also offer an alternative approach.  相似文献

The serious leisure inventory and measure (SLIM) was tested with 348 chess players to confirm the factors, assess the effects of method bias, and propose a set of the best-performing items for the 18 factor SLIM. The 54-item SLIM demonstrated acceptable fit and reliability values. The effect of method bias was evidenced in the sample and explained one-third of the variance. Inspection of factor loadings, when controlling for method bias, yielded one best-performing item per factor. Findings indicate method bias continues to be problematic for self-report measures such as the SLIM.  相似文献

In recent years there has been an increasing focus on the missing “T” of technology and “E” of engineering in early childhood STEM (science, technology, engineering, mathematics) curricula. Robotics offers a playful and tangible way for children to engage with both T and E concepts during their foundational early childhood years. This study looks at N = 60 children in pre-kindergarten through second grade who completed an 8-week robotics curriculum in their classrooms using the KIWI robotics kit combined with a tangible programming language. Children were assessed on their knowledge of foundational robotics and programming concepts upon completion of the curriculum. Results show that beginning in pre-kindergarten, children were able to master basic robotics and programming skills, while the older children were able to master increasingly complex concepts using the same robotics kit in the same amount of time. Implications for developmentally appropriate design of technology, as well as structure and pace of robotics curricula for young children are addressed.  相似文献
