Bioassay-guided fractionation of two Philippine sponges of the genus Petrosia has resulted in the isolation of the novel natural product cribrostatin 7 (1) and the known compounds renierone (2) and O-demethylrenierone (3). The structures of these isoquinoline quinones were determined by interpretation of spectroscopic data. Compounds 1, 2 and 3 were cytotoxic against the HCT 116 human colon car...

This paper presents a test of multi-period asset pricing models using quarterly Philippine data. Using a consumption-based asset-pricing model, the study finds the rate of time preference to be 5.20 percent (on an annual basis). The estimated risk aversion coefficient of 0.043 seems to be on the low side when compared with estimates for other countries. Hansen's J-test finds favorable evidence ...

The first consignment of crinoids received from the United States Fisheries steamer Albatross, now engaged in work among the Philippine Islands, proves to be a collection of more than usual interest. Not only does it contain a remarkably large number of new and interesting forms, but many species, heretofore known only from single more or less imperfect specimens, are represented. The littoral ...

This study discusses the potential of electronic commerce (EC) and its impact among the newly emerging economies and the changing landscape of businesses. In assessing the global impact of EC, the study examines the different areas of EC in which Information Technology (IT) can play a vital role with a focus on access and use of infrastructure, global competitiveness and trade, the changing lan...

"This paper collects and analyzes the profession of interpreter in Philippine Islands during 16th 17th centuries texts from General Archive Indies."

After 20 years of implementing the Comprehensive Agrarian Reform Program or CARP in 1987, evidence to suggest that it has contributed to solving the poverty problem in the Philippine rural sector remains deficient. After spending a total of P137 billion1 on land distribution and support services to the program beneficiaries, the outcome is deemed lacking in terms of achieving social justice for...

Dr. Binford. This morning we shall continue with our plan of presenting each day a speaker to discuss leprosy as a disease, because primarily we are concerned with the patient. Dr. Jose C . Tolentino, the first speaker, who, since 1951, has been engaged in the research activities of the Leonard Wood Memorial in the Philippines, is head of the Clinical Research Branch of the Philippine Division ...

The Nankai Trough marks the location where the Philippine Sea Plate begins subducting beneath the Eurasian Plate. The Nankai Trough subduction system has played an important role in causing many catastrophic earthquakes, a phenomenon observed at many other subduction zones (Ando, 1975). Recent studies have established that fluids play a major role in the physical and chemical evolution of subdu...

During Leg 59 of the Deep Sea Drilling Project, five sites (447 to 451) were occupied and seven holes drilled between Okinawa and Guam in the Philippine Sea (Fig. 1). All holes except Hole 447 yielded common calcareous nannoplankton at certain intervals cored. Nannoplankton assemblages and their age assignments will be discussed for each site, and fossil lists for selected samples from Holes 44...
