This paper puts the case for using a pedagogical framework based on the principles of grammatical design in conjunction with
conventional creative problem solving strategies in higher education to foster learning for innovation and creativity. It
explores the design and delivery of an inaugural creativity and innovation course that used a combination of individual and
group projects to explore the combinatorial use of creative problem solving strategies and grammatical design schemas. Using
established creative thinking evaluation techniques and reflective practice journals offers a powerful path for the creative
development of innovative ideas. Testing (Torrance, Creativity in the classroom, 1977) found that the figurative based creative thinking scores of an experimental group of non-designer undergraduate students
significantly improved according to pre and post course tests. Two dimensional and three dimensional design assessment tasks
were completed in conjunction with a series of creative problem solving teamwork sessions. Standard SELTS course evaluation
also strongly suggests there is value in the active teaching of creativity strategies for the recognition of valuable problems
and the development of innovative solutions. 相似文献

This paper estimates information stickiness with regard to inflation expectations in the United States and the Eurozone for the 1981/06–2015/12 and 1998/Q4–2015/Q2 periods, respectively, and further investigates whether such information stickiness is state-dependent. Based on a bootstrap sub-sample rolling-window estimation, we find that information stickiness varies over time, which contradicts the strict time dependency implied under sticky-information theory. We provide evidence that information stickiness depends on inflation volatility, which indicates that information stickiness is state-dependent and that it has a time trend. Using a threshold model, we estimate structural changes in the state-dependence and time-trend of information stickiness. The results show that information stickiness has been more dependent on inflation volatility and has had a higher time-trend in both regions following the 2008 financial crisis. 相似文献

This paper addresses the applicability of the convex duality method for utility maximization, in the presence of random endowment.
When the underlying price process is a locally bounded semimartingale, we show that the fundamental duality relation holds
true, for a wide class of utility functions and unbounded random endowments. We show this duality by exploiting Rockafellar’s
theorem on integral functionals, to a random utility function. 相似文献

Santiago J. Gangotena 《The Review of Austrian Economics》2017,30(1):51-82
Neo-Walrasian conceptualizations and DSGE models are incompatible with the emergence of coordination and discoordination in economic activity. While many conceptualizations stemming from the Austrian tradition are generally consistent with these fundamental problems, their process driven approach is hampered by the use of equilibrium constructs. This paper argues for the adoption of formal models that avoid this problem by addressing the following questions. Why should Austrian macroeconomists model? Where do models fit in with respect to pure and applied theory? How to model without equilibrium? To answer this final question I present a structure that aids in the construction and communication of such models. 相似文献

Although a growing body of research has shown the positive impact of ethical leadership on workplace deviance, questions remain as to whether its benefits are consistent across all situations. In this investigation, we explore an important boundary condition of ethical leadership by exploring how employees’ moral awareness may lessen the need for ethical leadership. Drawing on substitutes for leadership theory, we suggest that when individuals already possess a heightened level of moral awareness, ethical leadership’s role in reducing deviant actions may be reduced. However, when individuals lack this strong moral disposition, ethical leadership may be instrumental in inspiring them to reduce their deviant actions. To enhance the external validity and generalizability of our findings, the current research used two large field samples of working professionals in both Turkey and the USA. Results suggest that ethical leadership’s positive influence on workplace deviance is dependent upon the individual’s moral awareness—helpful for those employees whose moral awareness is low, but not high. Thus, our investigation helps to build theory around the contingencies of ethical leadership and the specific audience for whom it may be more (or less) influential. 相似文献

Economic views held by the general public tend to differ significantly from those of economic experts. Would these differences fade away if people were exposed to some economic instruction? In this article, the authors identify college students' preconceptions about economic issues at the beginning of the semester, verify their persistence throughout the semester, and test whether their beliefs are correlated to course performance. The authors conduct a survey at the beginning and end of the semester on a sample of first-year students taking an economic principles course. They find evidence of preconception persistence and reasoning inconsistencies, pointing to some cognitive biases as a plausible cause. Most students do not integrate the newly learned tools into their thinking process, even if they perform well in tests. 相似文献

Previous research shows that consumers’ response to price and income changes is heterogeneous. In addition, evidence from national data often does not support the classical assumption of one commodity-one price. This paper introduces a data coherent generalization to the quadratic form of the almost ideal demand system (g-QUAIDS) that incorporates the sources of heterogeneity in the demand function and allows for regional price variation. Aggregation over consumers imposes a linearization to the g-QUAIDS that requires a new set of price indices. The results from an empirical study by using microdata from the Household Income and Expenditure Survey of Iran highlight the impact of aggregation bias in relation to the level of aggregation. An investigation of the predictive power of linear versus nonlinear g-QUAIDS in different aggregation levels provides practical recommendations for consumer demand analysis. 相似文献

Social capital refers to social networks and the norms of reciprocity, cooperation and trust associated with them. It can be studied at different levels of analysis. As previous literature suggests, social capital has aspects at both the individual and collective levels. However, theory development and empirical research have focused on separate, sometimes diverging levels. In an attempt to address this, this research examines the simultaneous influence of individual and regional social capital on the discovery and exploitation of entrepreneurial opportunities using individual-level data from the Global Entrepreneurship Monitor linked with regional-level data on social capital. The results show that individuals from regions with higher social capital are more likely to discover and to exploit entrepreneurial opportunities. Moreover, individuals having networks with other entrepreneurs are also more likely to identify a business opportunity and to become an entrepreneur. Also, we found that social capital at individual level had a greater effect than social capital at regional level in the two stages of the entrepreneurial process. 相似文献

The systemic change of 1989/1990 is usually identified as the critical juncture in the modern economic history of post-communist economies. While the change itself was indeed a remarkable moment in time, a branching point from which a multitude of new paths originated in most of the countries in Central and Eastern Europe, this was only partially true in the case of Hungary. If a critical juncture is sought for Hungary, it is more likely to be 1968, the year the New Economic Mechanism was launched. By applying the conceptual framework of historical institutionalism, the article argues that what made Hungary unique during the communist era and what rendered its position as a (one-time) frontrunner proved to be a serious constraint after the systemic change. The legacy of a pre-born welfare state, the constant need for compensating potential losers of any economic reform, along with short-sighted decision-making, have together generated specific path dependencies in the Hungarian trajectory of economic development. 相似文献
