Global Expansion (global + expansion)
Selected AbstractsA question of balance: prioritizing public health responses to harm from gamblingADDICTION, Issue 5 2009Peter J. Adams ABSTRACT Aim To provide an overview on the nature and importance of public health approaches to the global expansion of commercial gambling. Method Three key areas of public health activity are examined: harm minimization, health promotion and the political determinants for change. Findings The rapid proliferation of gambling experienced in many countries is driven by the commercial development of new products orientated around continuous and rapid mass consumption. This is particularly the case with ongoing refinements to electronic gambling machines and the development of new gambling technologies using the internet and mobile telephones. So far responses to negative impacts have, on the whole, focused upon individualized treatment interventions. A public health approach to gambling offers a broad range of strategies to tackle the wider implications of gambling expansion: harm reduction provides evidence-based strategies for managing identifiable harm; health promotion focuses upon communities building their capacity, knowledge and resilience with regard to the attractions of gambling, and action on the political determinants sets out to increase the accountability and reduce the conflicts of interest that influence government resolve in managing their gambling environments. Conclusion In this new environment of mass consumption, efforts in developing treatment responses to problem gambling need to be balanced with, at least, equal efforts in developing public health responses. With the expansion of commercial gambling occurring globally, international agencies could play a critical role in supporting public health initiatives. [source] Detection of bacteria associated with harmful algal blooms from coastal and microcosm environments using electronic microarraysENVIRONMENTAL MICROBIOLOGY, Issue 3 2007Edward A. Barlaan Summary With the global expansion of harmful algal blooms (HABs), several measures, including molecular approaches, have been undertaken to monitor its occurrence. Many reports have indicated the significant roles of bacteria in controlling algal bloom dynamics. Attempts have been made to utilize the bacteria/harmful algae relationship in HAB monitoring. In this study, bacterial assemblages monitored during coastal HABs and bacterial communities in induced microcosm blooms were investigated. Samples were analysed using denaturing gradient gel electrophoresis (DGGE) of the 16S rRNA gene. DGGE bands with peculiar patterns before, during, and after algal blooms were isolated and identified. Probes for six ribotypes representing organisms associated with Chatonella spp., Heterocapsa circularisquama, or Heterosigma akashiwo were used for analysis on NanoChip electronic microarray. In addition, a new approach using cultured bacteria species was developed to detect longer (533 bp) polymerase chain reaction-amplified products on the electronic microarray. The use of fluorescently labelled primers allowed the detection of individual species in single or mixed DNA conditions. The developed approach enabled the detection of the presence or absence and relative abundance of the HAB-related ribotypes in coastal and microcosm blooms. This study indicates the ability of electronic microarray platform to detect or monitor bacteria in natural and induced environments. [source] Migration of Highly Skilled Chinese to Europe: Trends and PerspectiveINTERNATIONAL MIGRATION, Issue 3 2003Guochu Zhang Since China's economic opening and reforms in 1978, the country has broadened and deepened its exchanges and relations with other countries. This has contributed to the increase in the scale of international migration of highly skilled Chinese abroad. The impact of the migration of highly skilled Chinese on China and the relevant nations particularly deserve attention and study. Following the earlier migration flows mainly to the United States, Japan, Canada, Australia, and New Zealand, the migration of highly skilled Chinese to Europe has become a notable new trend. Currently, the flow of international migration of highly skilled Chinese personnel is mainly oriented toward Europe and the United States. While studying abroad has been the main form of migration of the skilled, this has now been joined by the migration of technical and professional staff, and the trend is increasing. The main country of destination for Chinese students is the United States, which absorbs more than half of the total, while Australia and Canada receive the largest number of skilled Chinese manpower. The United States also receives a large number of Chinese technical personnel, but its proportion has declined, while the flow to Europe has sharply increased. This development may be attributed to the global expansion of economic, scientific and technological, as well as cultural and educational exchanges and cooperation. But it is also the result of an increase in the educational investment made by the Chinese people following the continuous increase in China's economic strength and the population's personal income. Of greater importance are the gaps between China and Europe at the scientific, technological, and educational levels and the research and marketing environment. The intervening changes in labour market and immigration policies in European and American countries accelerate the trend further. For all of these and other reasons, the spatial distribution of Chinese students will become more balanced and play a positive role in the promotion of mutually beneficial exchanges between China and other countries. [source] Placental insulin-like growth factor II (IGF-II) and its relation to litter size in the common marmoset monkey (Callithrix jacchus)AMERICAN JOURNAL OF PRIMATOLOGY, Issue 12 2009Julienne N. Rutherford Abstract The primate placenta produces a wide variety of hormones throughout gestation that regulate placental function and fetal growth. One such hormone is insulin-like growth factor-II (IGF-II), a peptide implicated in cell division, differentiation, and amino acid transport. IGF-II concentrations were measured in 23 common marmoset (Callithrix jacchus) term placentas from twin and triplet litters in order to determine whether previously described differences in fetoplacental phenotype such as placental and litter mass and placental surface area were related to differences in endocrine function. IGF-II was extracted from frozen tissue samples and measured using an enzyme-linked immunosorbent assay kit designed for human tissue, which was validated for marmoset placenta. IGF-II concentrations were not related to placental or litter mass, and twin and triplet placentas did not differ in total concentration. However, per individual fetus, triplets were associated with a significant 42% reduction in IGF-II concentration (P=0.03), and IGF-II concentration per gram of fetal mass was a third lower in triplet litters. The triplet placenta exhibits a global expansion of the surface area which was contrasted by a per unit area reduction in IGF-II concentration (r=,0.75, P=0.01), a pattern that explains why twin and triplet placentas overall did not differ in concentration. Per fetus, triplet pregnancies are associated with relatively less maternal mass, placental mass and microscopic surface area suggesting that the intrauterine growth of triplets is supported by systems that increase the efficiency of nutrient transfer. The finding that individual triplet fetuses are also associated with significantly lower IGF-II concentrations is consistent with the view that the marmoset fetoplacental unit exhibits a flexible pattern of placental allocation and metabolism. Plasticity in placental endocrine and metabolic function is likely to play an important role in the ability of the fetus to sense and accommodate the intrauterine environment and, by extension, the external ecology.
