This study attempts to identify firm characteristics that explain the disparity between the information content of accounting earnings and stock prices. Granger's causality concept was employed to classify sample firms into four groups: price-leading firms, feedback-system firms, earnings-leading firms, and no-causation firms. The feedback-system firms were either combined with the no-causation firms or eliminated entirely to form three sample groups. The entire sample firms then were divided into two classes. The first is for estimation, and the second is for prediction. Results indicate that firm size, capital structure, R-square of regressing prices at time t against earnings at time t – 1, R-square of regressing earnings at time t against prices at time t – 1, and percentage of shares held by institutions are the significant explaining variables. The application of the coefficient estimates to the hold-out sample indicates that 76.2% of the firms can be correctly classified into the corresponding groups. These results were consistent with those from canonical discrimination and other multivariate statistical methods. 相似文献

Following a review of current research in children's learning in technology education, and an examination of the kinds of knowledge demanded in contemporary technology education programs in elementary schools, I argue that what is needed in early technology education programs is the scaffolding of what I am calling technological stance. This construct acknowledges the socio-cultural character of technology as a human endeavor. In contrast to programs which are oriented to application of conceptual and procedural knowledge or to programs in which knowledge is generated through interpretation of interactions with materials and tools, programs which support technological stance position learners as critical inquirers into both tool-related and discursive practices of technology. 相似文献

This study provides a comprehensive examination of recent mutual fund performance by analyzing a large set of both mutual funds and fund attributes in an effort to link performance to fund-specific characteristics. The results indicate that the hypothesized relationships between performance and the explanatory variables are generally upheld. After taking into consideration general market conditions and fund investment objective, the characteristic variables that relate to fund popularity, growth, cost, and management also explain performance. Finally, after controlling for survivorship and benchmark error as well as fund-specific factors, the results refute the performance persistence phenomenon. 相似文献

AbstractUlrich Beck fundamentally transformed our way of thinking about human interdependence through his three core theses on risk, individualisation and cosmopolitanisation. However, two commonly observed deficiencies in Beck’s grand theory were its Eurocentric orientation and a lack of empirical grounding. Based on 5 focus groups and 14 interviews with participants of the emerging Clean Food Movement in China, this paper extends the Beckian discussion outside Europe. Through examining how individuals understand both ‘traditional’ and ‘new’ risks associated with contemporary food consumption, this paper demonstrates that in the face of unpredictable and incalculable harms, risks are not seen as a ‘thing’, but are translated into ‘causal relations’. Subsequently, for Chinese stakeholders, the best way to safeguard food risks is to enact more visible and functioning interdependent relations in the food system. This in turn has given rise to new forms of communities which cut across conventional geographic, socio-economic and political boundaries. The paper deepens a Beckian theorisation in two ways. First, it demonstrates that the ‘enabling’ effect of risk towards a cosmopolitan society is not limited to obvious global crises, such as climate catastrophes and financial meltdown. In fact, the mundane yet intimate concern of putting ‘good’ food in one’s dinner bowl already presses actors to form new social solidarities that are cosmopolitan in nature. Second, it goes beyond Beck’s assertion that the risk society has culminated in a cosmopolitan moment, and explores how a performative cosmopolitan community reshapes the ‘relations of definition’ to mitigate risks on the ground. 相似文献

Situated in the context of academia, this study integrates ideas from institutional theory, person‐environment fit theory and leadership research to conceptualize and examine the cross‐level link between the organizational‐level institutional logic of research commercialization and the entrepreneurial intentions of researchers. Multi‐level analyses based on a sample of 254 researchers working for 85 research group leaders in 49 German research institutes reveal that two distinct attributes of research group leaders – that is, their track records of entrepreneurial behaviour and their entrepreneurial intentions – play a significant role in transmitting the organizational‐level logic to the individual level. We also observe a complementary interaction between organizational‐level commercialization logic and the entrepreneurial track records of leaders. We discuss how these findings advance our understanding of science commercialization through academic entrepreneurship and how they inform institutional theory and theory development in other domains of entrepreneurship research. 相似文献
