US economic assistance to two Micronesian nations: Aid impact,dependency and migration     

Emil Friberg  Kendall Schaefer  Leslie Holen 《Asia Pacific viewpoint》2006,47(1):123-133

Abstract: The USA provides economic assistance to the Federated States of Micronesia and the Republic of the Marshall Islands under the Compacts of Free Association. Both economies demonstrate three of the four MIRAB components: migration, aid and bureaucracy. Only the remittance structure has not developed. Significant US assistance supported large government sectors in both nations. Reductions in US assistance of over a 17‐year period led many island citizens to migrate to the USA. However, to date, remittances have not been substantial. In addition to structural challenges, both nations face institutional constraints including poor governance and lack of accountability over assistance. To improve future growth through more effective use of US assistance, these institutional constraints must be overcome. Future US assistance to both nations will fall over the next 20 years, putting pressure on the island governments and will likely contract their economies. The need for remittance streams is likely to increase. New Compact assistance structures strive to improve aid accountability.  相似文献   

Mirex residues in bobwhite quail after aerial application of bait for fire ant control, South Carolina--1975-76     

R J Kendall  R Noblet  J D Hair  H B Jackson 《Pesticides monitoring journal》1977,11(2):64-68

Mirex, the organochlorine compound used for control of the imported fire ant (Solenopsis invicta Buren), was applied aerially under supervision of the South Carolina Plant Pest Regulatory Service in October 1975 to a game management area in Hampton County, S.C. Influenced by recent reports indicating that low levels of mirex were toxic to certain nontarget organisms in laboratory studies, authors initiated a program for monitoring mirex residues in bobwhite quail (Colinus virginianus). Pretreatment residues were recorded on a dry-weight basis in bobwhite quail breast and adipose tissue; conversion factors for determining wet-weight concentrations are approximately as follows: fat, 0.77; and breast, 0.29. Residues ranged from 0.000-0.178 ppm and 0.247-2.763 ppm, respectively. Mirex residues in quail adipose tissue showed up to five-fold increase within the first month after treatment and declined thereafter. A residue peak was noticed the spring following mirex treatment, corresponding with insect emergence. Mirex residues in quail collected in summer 1976 following a fall bait application showed slightly higher residue levels than had birds taken in summer 1975; however, little, if any, human food chain contamination would result in the consumption of birds with residue levels found in this study.  相似文献   

Pesticide residues in foodstuffs in Great Britain. XV.—Triphenyltin residues in potatoes     

B. Thomas  Hazel L. Tann 《Pest management science》1971,2(1):45-47

An analytical method and results are given for the determination of triphenyltin residues in potatoes. Of the 44 samples analysed 35 contained residues of 0.001 ppm or less; residues in 6 of the samples were in the range 0.002–0.005 ppm and in 3 samples in the range 0.006–0.008 ppm.  相似文献

Did transmission of Helicobacter pylori from humans cause a disease outbreak in a colony of Stripe-faced Dunnarts (Sminthopsis macroura)?

ABSTRACT: Since the discovery that Helicobacter pylori causes a range of pathologies in the stomachs of infected humans, it has become apparent that Helicobacters are found in a diverse range of animal species where they are frequently associated with disease. In 2003 and 2004, there were two outbreaks of increased mortality associated with gastric bleeding and weight-loss in a captive colony of the Australian marsupial, the Stripe-faced Dunnart (Sminthopsis macroura). The presence of gastric pathology led to an investigation of potential Helicobacter pathogenesis in these animals. Histological examination revealed the presence of gastritis, and PCR analysis confirmed the presence of Helicobacter infection in the stomachs of these marsupials. Surprisingly, sequencing of 16S rRNA from these bacteria identified the species as H. pylori and PCR confirmed the strain to be positive for the important pathogenesis factor, cagA. We therefore describe, for the first time, an apparent reverse zoonotic infection of Stripe-faced Dunnarts with H. pylori. Already prone to pathological effects of stress (as experienced during breeding season), concomitant H. pylori infection appears to be a possible essential but not sufficient co-factor in prototypic gastric bleeding and weight loss in these marsupials. The Stripe-faced Dunnart could represent a new model for investigating Helicobacter-driven gastric pathology. Infections from their human handlers, specifically of H. pylori, may be a potential risk to captive colonies of marsupials.  相似文献

Production of volatiles in brown boronia flowers after harvest. I: Effect of clonal type and incubation temperature     

Hazel S. Mactavish  Robert C. Menary 《The Journal of Horticultural Science and Biotechnology》2013,88(4):436-439

Summary

The potential for enhanced concentrations of essential oils (solvent-extracted floral products) in flowers from four genetically distinct clones of brown boronia (Boronia megastigma Nees) as a result of post-harvest incubation was assessed. Flowers were sampled throughout 48 h of incubation at 12 and 308C. There was significant variation in the changes observed between clones. Increases in the concentration of floral extract as a result of incubation varied from 3% to 19%, the maximum concentration of floral extract observed was 2.13% (dry-weight basis). The volatile portion of the extract increased by between 25 and 117%, and the concentration of b-ionone, the main volatile of interest, increased by between 45 and 181%. The maximum concentration of total volatiles observed was 0.47%, and of b-ionone, 0.165%; all values being expressed as a percentage of dry flower weight. The most significant increase in floral extract, total volatiles and b-ionone after harvest, occurred in clone 250. Increases in all components were greater as a result of incubation at 128C for 48 h compared with 308C for 12 h.  相似文献   

Small intestine histomorphometry of beef cattle with divergent feed efficiency     

Yuri Montanholi  Ananda Fontoura  Kendall Swanson  Brenda Coomber  Shigeto Yamashiro  Stephen Miller 《Acta veterinaria Scandinavica》2013,55(1):9

Background

The provision of feed is a major cost in beef production. Therefore, the improvement of feed efficiency is warranted. The direct assessment of feed efficiency has limitations and alternatives are needed. Small intestine micro-architecture is associated with function and may be related to feed efficiency. The objective was to verify the potential histomorphological differences in the small intestine of animals with divergent feed efficiency.

Methods

From a population of 45 feedlot steers, 12 were selected with low-RFI (superior feed efficiency) and 12 with high-RFI (inferior feed efficiency) at the end of the finishing period. The animals were processed at 13.79 ± 1.21 months of age. Within 1.5 h of slaughter the gastrointestinal tract was collected and segments from duodenum and ileum were harvested. Tissue fragments were processed, sectioned and stained with hematoxylin and eosin. Photomicroscopy images were taken under 1000x magnification. For each animal 100 intestinal crypts were imaged, in a cross section view, from each of the two intestinal segments. Images were analyzed using the software ImageJ®. The measurements taken were: crypt area, crypt perimeter, crypt lumen area, nuclei number and the cell size was indirectly calculated. Data were analyzed using general linear model and correlation procedures of SAS®.

Results

Efficient beef steers (low-RFI) have a greater cellularity (indicated by nuclei number) in the small intestinal crypts, both in duodenum and ileum, than less efficient beef steers (high-RFI) (P < 0.05). The mean values for the nuclei number of the low-RFI and high-RFI groups were 33.16 and 30.30 in the duodenum and 37.21 and 33.65 in the ileum, respectively. The average size of the cells did not differ between feed efficiency groups in both segments (P ≥ 0.10). A trend was observed (P ≤ 0.10) for greater crypt area and crypt perimeter in the ileum for cattle with improved feed efficiency.

Conclusion

Improved feed efficiency is associated with greater cellularity and no differences on average cell size in the crypts of the small intestine in the bovine. These observations are likely to lead to an increase in the energy demand by the small intestine regardless of the more desirable feed efficiency.  相似文献
