This dissertation consists of three essays that examine various problems in financial economics. Chapter 1 fills in a gap in the IPO literature by documenting a close connection between IPO underpricing and the long-term underperformance of IPOs. Firms going public in periods of low underpricing do not underperform in the long run, while firms going public in high underpricing periods do. Furthermore, IPOs in later stages of high underpricing periods underperform even relative to their offer prices, which suggests that many of the most "underpriced" IPOs are in fact priced above fundamental value. This result is unlikely to be explained by differences in risk, or to be driven by a peso probl...
Examines the most important democratic challenges of today, using the Covid-19 pandemic as a case study.
Bambusa guadua, the tropical giant bamboo, is the most versatile, reliable architectural material of its native mountainous regions. Bamboo's delightful exterior and exotic reputation obscures its oaklike strength. 'New Bamboo' is a colour portfolio of contemporary structures and decorative designs demonstrating the appeal of building with natural materials for the modern eye. Properly treated, bamboo is as reliable as prime-grade hardwoods, beautiful in its own right, and suitable for commercial and residential structures in any climate. This is an anthology of bamboo construction by different experts: an agronomist, architects, a designer, and a builder, that showcases projects in Mexico, Brazil, Ecuador, Panama, and Colombia, where this product has been used as a traditional construction material for centuries. Also covered are France and Germany, where architects are discovering the delights of working with bamboo. Guadua is beautiful but not so delicate that it cannot be used in commercial structures like the auditorium-size pavilion built for the Hannover Expo 2000. Here are delightful details and rugged outbuildings that show bamboo as a most natural design element.
This book offers an analysis of Putin's approval ratings from the fall of the USSR to the present day. It considers contemporary materials, statistics and a discourse analysis to assess how Putin's approval ratings have stayed so high despite the current economic turndown. Through a comparative analysis with Yeltsin's time in office, the author demonstrates that higher levels of security, a better standard of living, increasingly assertive foreign policy and greater centralization of power led to positive approval ratings for Putin—absent characteristics during Yeltsin’s terms—and fostered 'positive national self-esteem' in Russia, a national sentiment that has persisted through current economic difficulties. Recommended reading for academics and students of Russian studies in the field of International Relations, Foreign Policy and Comparative Politics.
This volume provides the latest research on circulating tumor cells aimed for cancer researchers, scientists, and molecular oncologists. It presents the basic concepts behind circulating tumor cells (CTCs), metastatic biology, and potential applications as to how CTCs can be used in diagnostic biomarkers. CTCs are cells that have detached from the primary tumor and circulate in the bloodstream. Such cells may become "seeds" for the growth of additional tumors. The field of analysis surrounding cancer metastasis has been steadily growing, and CTCs provide effective biomarkers that can be examined in peripheral blood through a minimally invasive “liquid biopsy” procedure. CTCs offer several exciting applications, not only as markers of disease progression but also as biomarkers of monitoring response to therapy and companion diagnostics for novel anticancer drug development. In recent years there has been rapid growth and worldwide developments on CTCs, which span both the basic sciences and biomedical engineering fields.
