Abstract

Although studies have shown that supplemental instruction (SI) programs can have positive effects in introductory accounting courses, these programs experience low participation rates. Thus, our study is the first to examine the factors leading to student participation in SI programs. We do this through a survey instrument based on the Theory of Planned Behavior. Our study shows that students' attitudes toward the sessions affect their intent to participate in them. This attitude is influenced by students' perceptions that the sessions can help them in various ways. Results also show that influential others can influence student intent to participate in SI sessions. We also note that students' perceptions of the amount of personal control that they have over going to SI sessions have no effect on their participation in the sessions. We discuss how these findings can be leveraged to increase SI participation rates.  相似文献

The purpose of this article is to highlight the impact of a new range of field-work driven scholarly research regarding foreign R&D in China on the field of Chinese innovation studies. The field of China innovation studies is positioned for a major take-off with the opening up and broadening of the field to a new generation of scholars and experts, including the growing participation and contributions of Chinese nationals from the People's Republic of China (PRC). With the continued opening of China to the outside world has come also increased scholarly access which is allowing for research on issues that heretofore was constrained due to the limited availability of information as well as political and national security sensitivities. The field also is benefiting from the increased visibility being given to innovation matters by the Chinese government and the rise in the number of foreign R&D centres that have been established by foreign companies. New ‘internally-focused’ questions related to R&D spending, the cultural and historical setting for innovation, and the institutional structure are being addressed with some promising results. In addition, a whole new series of ‘externally-focused’ questions also are beginning to dominate the research agenda as more and more foreign firms seek to take advantage of China's improved climate for overseas business as well as the growing number of scientists and engineers at the higher end of the Chinese talent pool. The more we seem to find out, however, the more we realize we need to know to truly understand China's technological potential. That said, it is increasingly clear that foreign influence is having an important shaping effect on the nature of the PRC's R&D system, especially with respect to the strategic role played or potentially being played by returned scholars and experts whose more cosmopolitan perspectives serve as a real asset in building bridges between Chinese traditional attitudes and modes of behaviour towards new knowledge creation and the current institutional constraints on China's innovation trajectory since 1949.  相似文献

With the introduction of the exchange-traded German wind power futures, opportunities for German wind power producers to hedge their volumetric risk are present. We propose two continuous-time multivariate models for wind power utilization at different wind sites, and discuss the properties and estimation procedures for the models. Applying the models to wind index data for wind sites in Germany and the underlying wind index of exchange-traded wind power futures contracts, the estimation results of both models suggest that they capture key statistical features of the data. We show how these models can be used to find optimal hedging strategies using exchange-traded wind power futures for the owner of a portfolio of so-called tailor-made wind power futures. Both in-sample and out-of-sample hedging scenarios are considered, and, in both cases, significant variance reductions are achieved. Additionally, the risk premium of the German wind power futures is analysed, leading to an indication of the risk premium of tailor-made wind power futures.  相似文献

Over the past 50 years, we have witnessed considerable growth in business education, increased competition among business schools, and higher expectations for faculty scholarship. Increasing competition among scholars for limited publication opportunities in top‐tier journals and the proliferation of bottom‐tier journals has given rise to a variety of systemic ethical issues and dilemmas, for scholars and their institutions. In this article, we critically examine the current state of normative publishing activities and expectations, including doctoral education, promotion and tenure processes and research expectations, editorial and peer review processes, academic freedom, acceptable breadth, depth, and accuracy or legitimacy of research designs and methodologies, academic integrity, replication, and data availability concerning the trends and implications of contemporary and future management scholarship. We also provide recommendations for additional research and discussion on these issues.  相似文献

With the objective of identifying instability signatures of the financial system, this article integrates two classes of data-driven techniques. The first class of techniques is utilized to investigate macroeconomic behaviour by aggregating an ensemble of heterogeneous nonstationary time-series data and the second class of techniques examines the local dynamics of the microstructures in each time series. Moving window principal component analysis (PCA) and functional PCA (fPCA) are shown to extract collective signatures of the financial system for understanding macroeconomic behaviour, and the Synchrosqueezing and Markov switching techniques are used to study local dynamics within each individual time series. The integrated data analytics successfully identifies the diverse events from 1986 to 2012. All events, both major and minor, have been identified by fPCA. The major economic events, especially the 2008 Great Recession, along with several minor events, showed a strong leading indicator in the density index derived from Synchrosqueezing. The capability of this integrated analytics suite is demonstrated in this article, and it motivates further studies encompassing data sets from broader sectors. As a complement to existing model-driven approach, this would lead to achieving a robust and reliable method that can help in taking measures to avoid catastrophic collapse in the constantly evolving financial system.  相似文献

  • This paper examines the Meth Project, a social marketing campaign that enlists violence and fear to persuade Anglo and Hispanic youth in the USA to avoid methamphetamines. Violent and graphic media spots, although perhaps initially effective for facilitating message acceptance, may be counterproductive for long‐term campaign objectives. We draw on Witte's Extended Parallel Process Model to conceptualize how fear, risk, and behavior drive health‐related behaviors. Merely translating the Anglo spots into Spanish is an insufficient strategy to reach Hispanic youth because it targets rather than tailors its message. Significant findings of content analyses show that public service announcements in Spanish, unexpectedly, underscore recovering users' concern for violating norms with schools, employers, and law enforcement (secondary groups), whereas the Anglo spots show users more upset for disappointing family, friends, and loved ones (primary groups). Culturally appropriate Latino spots should tailor their messages to the values of familism, collectivism, simpatía, personalismo, and respeto, which have implications for reaching Hispanic audiences in other social marketing contexts.

We examine the role of venture capital backing on informational externalities generated by IPO firms. Theoretical models predict that going public firms generate positive externalities creating a spillover effect for other firms to go public. In this paper, we posit that venture backed IPOs convey positive information about industry and this information is transferred to rival firms. We also hypothesize that intra-industry information transfer varies with rivals’ characteristics and IPO price revisions generate additional information that affects rivals’ valuation. The results show that rivals have positive valuation effects in response to venture backed IPOs and no significant reaction in response to non-venture backed IPOs. We find evidence that the effect on rival firms is stronger if they operate in less concentrated industries and have high growth opportunities. The larger the IPO proceeds, the higher the magnitude of rivals ‘valuation effects. Positive (negative) information revealed in the form of upward (downward) price revisions significantly impacts rivals’ reaction in response to venture backed IPOs.  相似文献

Utility functions are regarded as elements of a linear space that is paired with a dual representation of choices to demonstrate the similarity between preference revelation and the duality of prices and quantities in revealed preference. With respect to preference revelation, quasilinear versus ordinal utility and choices in an abstract set versus choices in a linear space are distinguished and their separate and common features are explored. The central thread uniting the various strands is the subdifferentiability of convex functions.  相似文献
