建章宫“一池三山”的布局源于汉武帝的神仙信仰。受此影响,其中的仙山形象应是上广中狭的台状构筑物。此种台状仙山与汉代慕拟自然的假山形象并行发展,成为后世皇家园林“一池三山”的主要表达方式。通过对汉代图像资料中的仙山形象进行梳理,并结合相关的文献记载,对“一池三山”的仙山形态进行探究。进而分析了这一仙山形态在古典园林仙境景观中的发展演变,及其与汉代园林中用于迎仙的台的区别与联系,为进一步理解早期园林中的景观内容提供新的线索。 相似文献

In mergers and acquisitions, the acquiring firm must combine two firms’ resources and capabilities so that the outcome yields value. In individual firms, the marketing & sales, and R&D functions have typically developed intertwined and complex relationships over time. These multifaceted dependencies may obscure the integration of the firms and their functions. In order to reveal to what extent cross-functional relationships determine the success or failure of an acquisitions, we have made one of the first attempts to study merging firms’ function-specific capabilities, underlying microfoundations, and their cross-functional relationships during the integration process—instead of focusing on acquisition capabilities as such. We use longitudinal data from two cross-border acquisitions between US and Finnish SMEs. Our results indicate that major differences between merging firms’ cross-functional microfoundations—that is, their structures, processes, routines, and skills—might either enforce or erode the seemingly promising synergies at the product and market levels, depending on managerial awareness of their nature. 相似文献

This paper compares the resilience of ethical (Islamic and socially responsible) indexes among five developed (US, UK, Japan, Canada, Australia) and three emerging markets (Brazil, India, South Africa) during the period following the 2008 subprime crisis. It relies on a multivariate CAPM-EGARCH model that accounts for sudden changes in volatility through the application of an iterated cumulative sums of squares (ICSS) algorithm on daily data over the sample period 2008–2014 to model time-varying volatility and ensure reliable estimates. The study confirms the lower systemic risk associated with Islamic indexes during the bearish period and reports that SRI, despite being more subject to systemic risk, offered higher alphas in highly integrated markets, while Islamic indexes performed better in less integrated ones. The evidence also reveals a very limited increase in the models’ predictability power from the integration of sudden changes in volatility into the EGARCH models during the full sample period. This limit is more marked during the bearish sub-period. Our findings have important implications for international investment and portfolio diversification perspectives in times of financial downturn. 相似文献

This paper evaluates ways of instilling project management skills into accounting-based learning by the use of an iterative A3 planner to plan, monitor and review assignment progress. The application of an A3 planner to facilitate a project-based learning (PBL) group assignment in undergraduate accounting education has been critically evaluated in terms of both the student and tutor experience. The study uses a mix of qualitative and quantitative data. Quantitative data assisting exploration of perceptions were collected through 100 undergraduate students. A series of focus group discussions were carried out to investigate students’ engagement and tutors’ teaching experiences regarding the adoption of the A3 planner. The results suggest that the A3 planner promotes active planning and effective management of a PBL group assignment. It makes students’ thought processes more visible thereby facilitating and enhancing the tutoring/mentoring process. Moreover a more interactive and transparent approach by doing assignment via the use of an iterative A3 planner has ensured more feedback points and action based efficiency in the doing approach for learners. 相似文献

Facing the rapidly ageing society and shrinking of markets at home, Japanese firms are expanding outbound mergers and acquisitions (M&A) activity at a record pace. This study examines the determinants of Japanese cross‐border M&A activity focusing on the role of migrant networks in overcoming the informational barriers to such activity. Migrants include immigrants residing in Japan as well as Japanese citizens residing abroad. Our results suggest that the presence of immigrants and of Japanese citizens residing abroad both increase the probability of acquiring assets in a potential target country. Moreover, both communities exert positive effects on the number and value of outbound M&A deals. 相似文献

ABSTRACT We explore the link between third-party certification (venture capital backing, analyst following and having a top underwriter), and post-IPO acquisition activity through the reduction in valuation uncertainty channel. In a sample of 2,424 U.S. IPOs, we find that third-party certification facilitates post-IPO acquisitions. The certified firms are both more likely and conduct acquisitions sooner after the IPO. Our results support the notion that third-party certification reduces post-IPO valuation uncertainty and thereby facilitates a more efficient acquisition strategy. 相似文献

We study the development of social capital through adult civic engagement, in relation to social capital exposure having occurred during childhood based on experiences outside the family at primary school. We assume that the types of classmates in attendance at a child's school would have influenced her/his social capital. To identify the types of classmates, we take advantage of the heterogeneity in the ability levels of British primary-school classes during the 1960s. At that time, some schools were practicing a method of streaming, whereas others were not. Using British National Child Development data, we construct a single score of civic engagement and evaluate the effect on adult civic engagement of attending homogeneous-ability classes versus nonhomogeneous-ability classes and being in high-, average- or low-ability classes when enrolled in streamed schools. Our results show that children who were grouped in homogeneous-ability classes developed a lower interest in civic engagement than their peers who attended mixed-ability classes (nonstreamed schools). Moreover, among children who attended streamed schools, a lower attitude toward civic engagement was observed among low-ability students. Thus, streaming appears to be detrimental to social capital development, especially for low-ability individuals. 相似文献

This study analyzes how mergers and acquisitions (M&A) affect the performance of acquired companies in Japan. The sample period includes the era in which the government of Japan promoted a series of corporate governance reforms. A difference-in-differences analysis is implemented to eliminate the endogenous effects of a corporate acquisition. Choosing a control group by propensity score matching, we find that acquisitions have significantly negative effects on employment but no significant effects on labor productivity. For acquisitions by Japanese companies, we also find no significant improvement in ROA but significant improvement in Tobin’s q. The results are consistent with the zombie company theory, which indicates that an M&A prolongs the life of an insolvent company. Acquisitions by Japanese companies are in contrast with those by foreign companies, which have positive effects on ROA. 相似文献
