Taxonomic results of the Bryotrop expedition to Zaire and Rwanda : 32., Bryaceae
16 species of Bryaceae collected during the Bryotrop expedition to Rwanda and Zaire were examined resulting in 7 new records for Central Africa
Contributions toward a bryoflora of the Aberdare Range, Kenya
124 species of bryophytes, belonging to 46 families are reported for the Aberdare Mountains, of which 58 species are new for the Aberdares and 6 records are new for Kenya, indicated by * and ** respectively. The wetter, more humid southern and south-eastern parts of the range contain the greatest diversity of species, particularly in the montane forests while the drier northern part is poor in species
Contribution to the bryoflora of Kenya
109 species of bryophytes are presented from various localities in Kenya, among which are thirteen new records (marked with **) for the country
Data to the bryoflora of Mount Kenya, Kenya
194 species of bryophytes, belonging to 61 families are reported from Mount Kenya, of which 38 species are new for Mount Kenya and 30 records are new for the whole country, marked by * and ** respectively. The montane forests between 1600 and 3300m. asl., contain the greatest diversity of life forms and species. This is due to the abundant rainfall providing adequate humidity at relatively low temperature and altitude, coupled with frequent cloud cover. All vegetation belts above the montane forests experience large diurnal fluctuations in temperatures, intense solar radiation, added by the fact that the rainfall is relatively low and erratic or at times fall in the form of hail or snow resulting in a low diversity of species and life forms except in very sheltered habitats such as rock crevices in rocky outcrops. Solifluctions soil conditions occuring between 3850 and 4450m. asl. exhibit moss balls growth forms. The summits of Batian (5199m.), Nelion (5188m.) and Lenana (4985m.) harbour small cushions of Grimmia affinis and Andreaea cucullata. The greatest number of species are found in the wetter southern, south-western and south-eastern slopes unlike the drier northern, north-western and north-eastern slopes of the mountain. Species commonly found in the wetter areas are Bryum preussii, Bryum keniae, Prionodon ciliatus, Hypopterygium viridissimum, Plagiochila barteri, Plagiochila squamulosa, Radula recurvifolia, Porella hoehnelii, Dumortiera hirsuta while Pterogonium gracile, Leptodon smithii and Hedwigia ciliata are characteristic of the drier areas
Bryophytes from Saiwa Swamp National Park, Kenya
57 species of bryophytes belonging to 30 families are reported from Saiwa Swamp National Park, of which 57 species are new for Saiwa Swamp National Park and 10 records are new for Kenya, indicated by * and ** respectively. Although small in surface area (15.5 sq.km.) the park represents an undercollected area in Kenya with a good diversity of bryophytes
Asia-Pacific Trade and Investment Review
This chapter shows that the Republic of Korea has experienced significant change in both trade and foreign direct Investment (FDI) flows since the 1997 Asian financial crisis. The analysis indicates that a rapid increase in exports at the onset of the crisis helped to improve foreign reserves of the Republic of Korea and also helped the economy to recover from severe recession. Despite the crisis, the importance of the Chinese market has steadily increased to the point where it is the most important export market for the Republic of Korea, largely at the expense of the Association of Southeast Asian Nations (ASEAN) market. The crisis also had a significant impact on FDI inflows, both in terms of source country and host industry. FDI increased sharply following the crisis, and this rapid increase was largely due to higher United States and European Union investment in the service sector, which is consistent with the wealth effect hypothesis on FDI flows. Meanwhile, Japanese FDI decreased, resulting in a decline in FDI in the manufacturing sector. However, the expected spillover effects of FDI are debatable, due to largely to a shape increase in mergers and acquisitions, and FDI dried up in technology-intensive manufacturing industry. In contrast, the Republic of Korea's outward direct investment seemed to be little influenced by the financial crisis, although a further study of the implications of the crisis for the Republic of Korea's outward direct investment in developing countries, including the traditionally popular Asian region, also needs to be investigated further.Korea, FDI, ODI, export, Asian financial crisis, 1997
Optimal and efficient crossover designs for comparing test treatments with a control treatment
This paper deals exclusively with crossover designs for the purpose of
comparing t test treatments with a control treatment when the number of periods
is no larger than t+1. Among other results it specifies sufficient conditions
for a crossover design to be simultaneously A-optimal and MV-optimal in a very
large and appealing class of crossover designs. It is expected that these
optimal designs are highly efficient in the entire class of crossover designs.
Some computationally useful tools are given and used to build assorted small
optimal and efficient crossover designs. The model robustness of these newly
discovered crossover designs is discussed.Comment: Published at http://dx.doi.org/10.1214/009053604000000887 in the

Luminosity Profiles of Merger Remnants
Using published luminosity and molecular gas profiles of the late-stage
mergers NGC 3921, NGC 7252 and Arp 220, we examine the expected luminosity
profiles of the evolved merger remnants, especially in light of the massive CO
complexes that are observed in their nuclei. For NGC 3921 and NGC 7252 we
predict that the resulting luminosity profiles will be characterized by an
r^{1/4} law. In view of previous optical work on these systems, it seems likely
that they will evolve into normal ellipticals as regards their optical
properties. Due to a much higher central molecular column density, Arp 220
might not evolve such a ``seamless'' light profile. We conclude that
ultraluminous infrared mergers such as Arp 220 either evolve into ellipticals
with anomalous luminosity profiles, or do not produce many low-mass stars out
of their molecular gas complexes.Comment: Final refereed version. Note new title. 4 pages, 2 encapsulated color
