Population structure and inbreeding in a rare and declining bumblebee, Bombus muscorum (Hymenoptera: Apidae)
No full textOwing to habitat loss populations of many organisms have declined and become fragmented. Vertebrate conservation strategies routinely consider genetic factors, but their importance in invertebrate populations is poorly understood. Bumblebees are important pollinators, and many species have undergone dramatic declines. As monoandrous social hymenopterans they may be particularly susceptible to inbreeding due to low effective population sizes. We study fragmented populations of a bumblebee species, on a model island system, and on mainland Great Britain where it is rare and declining. We use microsatellites to study: population genetic structuring and gene flow; the relationships between genetic diversity, population size and isolation; and frequencies of (sterile) diploid males — an indicator of inbreeding. We find significant genetic structuring (? = 0.12) and isolation by distance. Populations > 10 km apart are all significantly differentiated, both on oceanic islands and on the mainland. Genetic diversity is reduced relative to closely related common species, and isolated populations exhibit further reductions. Of 16 populations, 10 show recent bottlenecking, and 3 show diploid male production. These results suggest that surviving populations of this rare insect suffer from inbreeding as a result of geographical isolation. Implications for the conservation of social hymenopterans are discussed.<br/
MeSH term explosion and author rank improve expert recommendations
No full textInformation overload is an often-cited phenomenon that reduces the productivity, efficiency and efficacy of scientists. One challenge for scientists is to find appropriate collaborators in their research. The literature describes various solutions to the problem of expertise location, but most current approaches do not appear to be very suitable for expert recommendations in biomedical research. In this study, we present the development and initial evaluation of a vector space model-based algorithm to calculate researcher similarity using four inputs: 1) MeSH terms of publications; 2) MeSH terms and author rank; 3) exploded MeSH terms; and 4) exploded MeSH terms and author rank. We developed and evaluated the algorithm using a data set of 17,525 authors and their 22,542 papers. On average, our algorithms correctly predicted 2.5 of the top 5/10 coauthors of individual scientists. Exploded MeSH and author rank outperformed all other algorithms in accuracy, followed closely by MeSH and author rank. Our results show that the accuracy of MeSH term-based matching can be enhanced with other metadata such as author rank
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Thoracoscopic-assisted esophagectomy and laparoscopic gastric pull-up for lye injury.
No full textBACKGROUND: Acquired esophageal strictures in children are often the result of ingestion of caustic agents. We describe 2 children with severe esophageal strictures following lye ingestion, who successfully underwent esophagectomy and gastric pull-up utilizing combined thoracoscopic and laparoscopic techniques. METHODS: This was a retrospective chart analysis of both patients. CASE 1: A 17-year-old female, who ingested a lye-containing substance, which lead to the need for gastrostomy and esophageal dilatations, developed an esophageal stricture. Thoracoscopic esophagectomy, laparoscopic gastric conduit creation, pyloroplasty, gastric pull-up, and esophagogastric anastomosis was performed one year later. She was tolerating a regular diet for almost 4 years following esophageal replacement when she developed a gastric ulcer with gastrobronchial fistula that required open repair via a right thoracotomy. She has since recovered and resumed her regular diet. CASE 2: A 13-month-old female who ingested a lye-based cleaner underwent tracheostomy and gastrostomy on the day of injury, and esophageal dilatations beginning 1 month later. Despite dilatations, she developed severe strictures for which at age 21 months she underwent thoracoscopic esophageal mobilization, laparoscopic creation of gastric conduit, pyloroplasty, and esophagogastric anastomosis. A right thoracotomy was necessary to negotiate the conduit safely up to the neck. She is tolerating feeds and has not developed any complications for nearly 3 years following esophageal replacement. CONCLUSIONS: Esophagectomy and gastric pull-up for esophageal lye injuries can be accomplished utilizing a combination of thoracoscopy and laparoscopy with excellent results. Long-term follow-up is necessary to manage potential complications in these patients
"Closing the R&D Gap, Evaluating the Sources of R&D Spending"
No full textBoth spending and tax policies have been implemented in the United States with the goal of stimulating private sector research and development (R&D). Karier questions whether current R&D policy, especially the research and experimentation tax credit, can contribute to closing the gap between nondefense expenditures on R&D in the United States and such expenditures in other countries, such as Japan and Germany. He also explores possible changes to our current R&D policy to make it more effective.
