Notas de Población Vol.33 N° 83

Las relaciones entre población y pobreza han sido uno de los focos de interés y actividad del Centro Latinoamericano y Caribeño de Demografía (CELADE)- División de Población de la CEPAL desde sus inicios, hace ya 50 años. En este contexto el CELADE organizó la Reunión de expertos sobre población y pobreza en América Latina y el Caribe en noviembre de 2006 con el objetivo general de examinar y analizar las interrelaciones relevantes entre las tendencias y los factores demográficos, la pobreza y las políticas de protección social en la realidad actual de América Latina y el Caribe. Los temas abordados en la reunión fueron: i) los aspectos conceptuales y metodológicos de las interrelaciones entre población y pobreza, con particular referencia a la situación de América Latina y el Caribe; ii) las diversas maneras en que la pobreza afecta y se ve afectada por variables y fenómenos demográficos, distinguiendo entre estos últimos a la salud sexual y reproductiva, el envejecimiento de la población y las migraciones internas e internacionales; iii) los efectos de las políticas orientadas a enfrentar la pobreza, a dar protección social a la población en general y a grupos específicos como las mujeres, los jóvenes y la población indígena; iv) la dinámica de la población de los países de la región y su influencia en los requerimientos sociales presentes y futuros, y v) las políticas de protección social aplicadas en América Latina y el Caribe, en particular su importante aporte a la superación de la pobreza de la población, y la consideración en estas de las realidades y tendencias demográficas. En este y el siguiente número de la revista “Notas de población” se dan a conocer algunos de los estudios presentados en esa reunión. Los diez artículos seleccionados cumplen con varios requisitos —amén de su calidad—, entre otros originalidad y focalización en las prioridades temáticas de la revista. En este número se presentan cinco artículos, el primero de los cuales es un análisis desde una perspectiva conceptual de las relaciones entre población y pobreza en el actual contexto socioeconómico, político y programático. Asimismo, se incluyen un artículo en que se examinan las relaciones entre el comportamiento reproductivo y la pobreza, otro en que se analizan los vínculos entre envejecimiento y pobreza, otro que se centra en la migración internacional y la pobreza y un último consistente en un análisis del efecto de algunos fenómenos demográficos a escala de hogar sobre la probabilidad de salir o de entrar a la pobreza.

The Martha Francis Morgan Papers includes teaching aids, reading lists and tests relating to her teaching; together with constitutions, correspondence, photographs, program notes, and newspaper clippings concerning her involvement with the many clubs and organizations in which she participated.

Family and Church Records - Accession 49 - M22 (32-33)

The Family and Church Records consist of photocopies of records compiled by Mrs. W.H. Hamilton, Mrs. Fred C. Laurence and Mrs. L.F. Abernethy for the Catawba Chapter of the Daughters of the American Revolution. The collection includes mostly genealogical information including a history of the Crawford family, Reid family bible records, Roach family bible records, Joseph Palmer Moore obituary, Moore family chart, Andrew Jackson, Sr. and Elizabeth Jackson monument, Commission from Gen. Francis Marion to Captain James Witherspoon, Witherspoon family records, Alexander Love biographical information, and a cemetery list of Bethel Presbyterian Church.

Sugarcane Growth Promotion by the Endophytic Bacterium Pantoea agglomerans 33.1

The promotion of sugarcane growth by the endophytic Pantoea agglomerans strain 33.1 was studied under gnotobiotic and greenhouse conditions. The green fluorescent protein (GFP)-tagged strain P. agglomerans 33.1: pNKGFP was monitored in vitro in sugarcane plants by microscopy, reisolation, and quantitative PCR (qPCR). Using qPCR and reisolation 4 and 15 days after inoculation, we observed that GFP-tagged strains reached similar density levels both in the rhizosphere and inside the roots and aerial plant tissues. Microscopic analysis was performed at 5, 10, and 18 days after inoculation. Under greenhouse conditions, P. agglomerans 33.1-inoculated sugarcane plants presented more dry mass 30 days after inoculation. Cross-colonization was confirmed by reisolation of the GFP-tagged strain. These data demonstrate that 33.1:pNKGFP is a superior colonizer of sugarcane due to its ability to colonize a number of different plant parts. The growth promotion observed in colonized plants may be related to the ability of P. agglomerans 33.1 to synthesize indoleacetic acid and solubilize phosphate. Additionally, this strain may trigger chitinase and cellulase production by plant roots, suggesting the induction of a plant defense system. However, levels of indigenous bacterial colonization did not vary between inoculated and noninoculated sugarcane plants under greenhouse conditions, suggesting that the presence of P. agglomerans 33.1 has no effect on these communities. In this study, different techniques were used to monitor 33.1:pNKGFP during sugarcane cross-colonization, and our results suggested that this plant growth promoter could be used with other crops. The interaction between sugarcane and P. agglomerans 33.1 has important benefits that promote the plant's growth and fitness.

Interannual variation in commercial oyster (Crassostrea gigas) farming in the sea (Florianopolis, Brazil, 27 degrees 44 ' S; 48 degrees 33 ' W) in relation to temperature, chlorophyll a and associated oceanographic conditions

Aquaculture of filter-feeding bivalve mollusks involves the fruitful conversion of marine particulate organic matter into premium protein of high nutritive value. Culture performance of bivalves is largely dependent on hydrological conditions and directly affected by e. g. temperature and chlorophyll levels. Accordingly, these parameters may be related with seasonality but also with oceanographic features combined with climate events. Yields of Pacific cupped oyster (Crassostrea gigas) reared at commercial procedures in suspended structures (long-lines) in a sheltered bay in Southern Brazil (Santa Catarina State, 27S 43'; 48 W 30') were evaluated in relation to local environmental conditions: sea surface temperature, chlorophyll a concentration, and associate effects of cold fronts events and El Nino and La Nina periods. Outputs from four consecutive commercial crop years were analyzed (2005/06, 2006/07, 2007/08, 2008/09) in terms of oyster survival and development time during the following grow-out phases of the culture cycle: seed to juvenile, juvenile to adult, adult to marketable. Since culture management and genetics were standardized significant differences verified among crop performance could be mostly related to environmental effects. Time series of temperature and chlorophyll a (remote sensing data) from crop periods displayed significant seasonal and interannual variation. As expected, performance during initial grow-out stages (seed to juvenile) was critical for final crop yield. Temperature was the main factor affecting survival in these initial stages with a trend of negative correlation, though not statistically significant. On the other hand, oyster development rate was significantly and positively affected by chlorophyll a concentration. Chlorophyll a values could be increased by upwelled cold nutrient-rich South Atlantic Central Water (SACW, related to predominant Northern winds) though further dependent on occurrence of Southern winds (cold fronts) to assist seawater penetration into the sheltered farming area. Lower salinity nutrient-rich northward drifted waters from La Plata River discharge may also result in chlorophyll a rise in the farming area. The El Nino period (July 2006 to February 2007) coincided with lower chlorophyll a levels in the farming site that may be related to both decreased number of cold fronts as well as predominance of Northern winds that retain northward spreading of La Plata River discharge waters. In contrast, the La Nina period (August 2007 to June 2008) corresponded to higher chlorophyll a values in the farming area by both upwelling of SACW and penetration of La Plata River discharge water assisted by increased occurrence of Southern winds and cold fronts. The recognition of the potentially changing climate and effects upon the environment will be an important step in planning future development of bivalve aquaculture.
