Increasing Recruitment (increasing + recruitment)
Selected AbstractsThe International Quotidian Dialysis Registry: Annual report 2005HEMODIALYSIS INTERNATIONAL, Issue 3 2005Gihad Nesrallah Abstract The International Quotidian Dialysis Registry was designed to collect data describing treatments, characteristics, and outcomes of patients treated with quotidian hemodialysis (HD) worldwide. In July 2004, North American centers were first invited to enroll patients. By March 1, 2005, a total of 70 nocturnal and 8 short-daily HD patients from three Canadian and two US centers were enrolled. As recruitment continues, projected enrollment for 2005 may exceed 200 patients from North America alone. Preliminary analyses indicate that the current registry cohort is younger (mean age, 49.5 ± 1.6 years) and carries a lower burden of comorbidity than the overall North American HD population. The low event rate expected in this cohort underlines the need for a large sample size if an appropriately powered survival study is to be undertaken. Increasing recruitment in the United States by including HD centers owned or managed by large dialysis organizations, and beginning overseas collaborations to include Australia, New Zealand, Europe, and South America will be the primary areas of focus for 2005. [source] Temporal and spatial responses of British Columbia steelhead (Oncorhynchus mykiss) populations to ocean climate shiftsFISHERIES OCEANOGRAPHY, Issue 1 2000Welch The pattern of temporal change in recruitment of steelhead trout (Oncorhynchus mykiss) entering the ocean between 1963 and 1990 was geographically coherent in all regions of British Columbia. A major increase in recruitment was evident for smolts entering the ocean after 1977. Subsequently, an out-of-phase response occurred after 1990, indicating that the effect of a possible 1990 regime shift had both temporal and geographical structure. Steelhead entering northern regions had increasing recruitment, while steelhead entering southern BC coastal regions had sharply decreasing recruitment. The evidence clearly indicates that the overall recruitment response since 1977 was primarily shaped by changes in marine (not freshwater) survival. Similar sudden changes in adult recruitment also appear to be occurring for other species of Pacific salmon in BC and Oregon, such as coho (O. kisutch), which appear to occur suddenly and show considerable persistence. A possible explanation for the change is that ocean productivity declined in coastal regions of southern BC after 1990, reducing the marine growth of juvenile salmon. The Bakun upwelling index shows a pattern of geographical coherence along the west coast of North America that could in principle explain the observed pattern of changes in recruitment. However, no evidence for a temporal shift in this index occurring around 1977 and 1990 is apparent. The reason for the sudden and persistent decline in ocean survival is therefore uncertain. [source] The career paths of a group of Romanian nurses in Italy: a 3-year follow-up studyINTERNATIONAL NURSING REVIEW, Issue 2 2008A. Palese rn, bnsc Purpose:, The objective of this study was to describe for how long a homogeneous group of 17 Romanian nurses who first arrived at the ,Teaching Hospital' in Italy in 2003, stayed in the same hospital/ward of the host country, why and when they decided to move from one hospital to another, and their levels of competence in core skills, after either 6 months or 3 years. Methods:, A longitudinal study design was adopted. The first phase was carried out in 2004, the second in 2006. We used an anonymous questionnaire. Results:, Only ten of the 17 nurses, who had started working in Italy 3 years before, remained in the same Hospital where they first started working. In spite of being given the opportunity to stay, some decided to move to hospitals where it is possible to earn more money or where they could save more by living in less expensive towns. The first nurse left the hospital in the first year, five in the second and one in the third year. Levels of perceived professional independence after 3 years are very good: the permanent group had improved their skills in all areas even though they felt a lack of confidence during the first 6 months. Conclusions:, This study, within the limits of the sample and the methods, shows that foreign nurses are highly mobile in the host country and this revolves around the opportunity to earn more. With increasing recruitment of nurses from within the European continent, it is necessary to continue studying the factors that sustain foreign nurses, to find out how they can be helped, how to value their imported professional skills, how to reduce the initial lack of faith in their own abilities and to discover which strategies would encourage them to stay in the hospital where they arrived. [source] Response of recruitment to light availability across a tropical lowland rain forest communityJOURNAL OF ECOLOGY, Issue 6 2009Nadja Rüger Summary 1. ,Many hypotheses about species coexistence involve differential resource use and trade-offs in species' life-history traits. Quantifying resource use across most species in diverse communities, although, has seldom been attempted. 2. ,We use a hierarchical Bayesian approach to quantify the light dependence of recruitment in 263 woody species in a 50-ha long-term forest census plot in Panama. Data on sapling recruitment were obtained using the 1985,1990 and 1990,1995 census intervals. Available light was estimated for each recruit from yearly censuses of canopy density. 3. ,We use a power function (linear log,log relationship) to model the light effect on recruitment. Different responses of recruitment to light are expressed by the light effect parameter b. The distribution of b had a central mode at 0.8, suggesting that recruitment of many species responds nearly linearly to increasing light. 4. ,Nearly every species showed increases in recruitment with increasing light. Just nine species (3%) had recruitment declining with light, while 198 species (75%) showed increasing recruitment in both census intervals. Most of the increases in recruitment were decelerating, i.e. the increase was less at higher light (b < 1). In the remaining species, the response to light varied between census intervals (24 species) or species did not have recruits in both intervals (41 species). 5. ,Synthesis. Nearly all species regenerate better in higher light, and recruitment responses to light are spread along a continuum ranging from modest increase with light to a rather strict requirement for high light. These results support the hypothesis that spatio-temporal variation in light availability may contribute to the diversity of tropical tree species by providing opportunities for niche differentiation with respect to light requirements for regeneration.
