The pollen, plant macrofossil and aquatic fossil stratigraphies from a transect of sites in the Sierra Nevada, California, were examined to deduce paleoenvironmental change since the late-Wisconsinan. Fossil pollen samples were compared to modern pollen samples from both sides of the Sierra Nevada crest. Modern samples corresponded largely to modern vegetation units, validating the use of pollen for this purpose in mountainous environments. Vegetation change during the Holocene was largely contemporaneous on both sides of the crest at elevations where lake cores and meadow sections were analysed. Deglaciation occurred by ca. 12,500 yr BP at a site on the east side, and by ca. 11,000 yr BP at a west side site. Prior to ca. 10,000 yr BP, few trees were found around the higher elevation sites. An open forest with trees characteristic of the modern Sierra Montane and Upper Montane forest grew around the mid- to high elevation sites by the early Holocene. Montane chaparral species, such as bush chinquapin, mountain mahogany and probably huckleberry oak, with sagebrush, were most abundant then. Along with lowered lake levels or absence of perennially standing water, and greater affinities to modern pollen samples from the more arid east side, these observations suggest drier conditions than today. However, by ca. 6500-5500 yr BP, effective precipitation increased, as shown by increases in subalpine conifers (mountain hemlock and red fir) and higher lake levels, and less affinities to modern samples from the east side. Modern vegetation developed at most sites within the last 2-3 millenia. Specific changes in the vegetation at this time included a reduction in upper elevational limits of mountain hemlock and red fir, with possible downslope retreat of whitebark pine, indicating greater cooling and/or wetter conditions. This is consistent with the record of wet meadow genesis as well as tree-ring and Neoglacial chronologies.

The nutritional status of 78 women was assessed during the third trimester of pregnancy. The study was conducted in military barracks in Sierra Leone with 39 adolescent women (<20 years) and 39 adult women (>20 years).Twenty-four hour dietary recall interviews and anthropometric measures were collected. Laboratory, clinical and physiological data were obtained from the subjects' medical records. The dietary analysis of the diets consumed by adolescent and adult women showed differences in the intakes of only calcium, phosphorous, potassium, selenium and sodium. The average diet consumed by the women was <2/3 the recommended guidelines for carbohydrate and <2/3 the Recommended Dietary Allowances for persons in the U.S. for kilocalories, protein, riboflavin, pyridoxine, folacin, pantothenic acid, cholesterol, calcium, iron, magnesium, phosphorous, sodium and zinc. The women consumed diets that were >100 percent of the RDA for vitamins A, C, E, niacin and selenium. Differences occurred in the infant birthweights and Apgar scores at 1, 5 and 10 minutes between women who had abnormal measures for hemoglobin, hematocrit, ketonuria, albuminuria, glycosuria and/or malaria parasites and the women who were healthy.Maternal weight gain, age and infant health status did not correlate. The average weight gain for all the women was 17.85 kg which is within the acceptable range recommended for pregnancy. Maternal weight-at-term, gestational age, triceps skinfolds, arm circumference, hemoglobin, hematocrit were correlated with infant birthweight, length and head circumference. Maternal hemoglobin and hematocrit further correlated with infant Apgar scores at 1, 5 and 10 minutes.Hemoglobin and hematocrit levels were very low for the average women in the study (X 9.7 g/dl and 29.7 percent respectively). The malaria reduced the infant birthweight by 431 g. Albuminuria and ketonuria were associated with reduced infant birthweight while modest glycosuria was associated with increased birthweight. / Department of Home Economics

This study attempts to elucidate aspects of the complex relationship between internal migration and development in Sierra Leone, a country marked by pronounced dualism. It argues that internal migration and its developmental facets such as remittances should be examined within their socio-economic and ecological context. The major findings can be summarised as follows: 1. Interregional migration was shown to be positively and significantly correlated with a composite index encompassing social and economic dimensions of development. 2. Since the trends in migration and development in the two sets of regions delineated positive net migration/more developed and negative net migration/less developed - have been in force for at least two decades and show no signs of narrowing regional inequality, suggest disequilibrium rather than equilibrium tendencies. This feature of the migration process was confirmed by analysis performed at the local level, which explicitly took into account, socio-economic and ecological factors along with the effects of government policies on rural outmigration. 3. A study of the determinants of interregional migration for a whole system, Sierra Leone, and its component economic sub-systems underline the importance of taking into consideration development dimensions in such analyses, 4. Finally, on the role of remittances in development, the study established that - a. Overall, that there was a net transfer of resources from the urban to the rural areas; b. In-remittances were found to be important to poorer rural households; c. Remittances received were used mainly for consumption purposes; and d. For the decision to send remittances, the common, significant variables for rural and urban households were those showing ties with origin areas; while for the decision on the size of remittances, they were the income of the head of the household and whether an unskilled manual worker or not.
