A revised and updated Odonata checklist of Samoa (Insecta: Odonata)
No full textOdonata records of the Samoan Archipelago are updated and an updated checklist provided. It is part of an ongoing assessment of the fauna, taxonomy and distributionof the Pacific island dragonflies. The checklist follows recent reviews published/prepared about the Solomon Islands, New Caledonia, Fiji and Kingdom of Tonga.
This study draws on recent dragonfly records following general insect surveys spanning 2008-2012 funded by Critical Ecosystem Partnership Fund (CEPF) via Conserva-tion International (CI) to the authors and to Secretariat Pacific Regional Environment Program (SPREP) and also by funding from Japan International Cooperation Agency (JICA). Other unpublished data from Samoan Archipelago and Niue are included as well. All, but one, of the newly collected Odonata species are widespread within the Pacific region. Hemicordulia cupricoloris the only species from the recent collections which is endemic to Samoa, previously reported for Savai'i and Upolu Islands. It has neverbeen confirmed since its original description in 1927. The new study shows the species as an inhabitant of high altitude zones of Savai'i. It is recommended inland areas of Savai'i and other islands within the Samoan Archipelago should be targeted in further field studies

Predictors of Stunting, Wasting and Underweight among Tanzanian Children Born to HIV-Infected Women.
No full textChildren born to human immunodeficiency virus (HIV)-infected women are susceptible to undernutrition, but modifiable risk factors and the time course of the development of undernutrition have not been well characterized. The objective of this study was to identify maternal, socioeconomic and child characteristics that are associated with stunting, wasting and underweight among Tanzanian children born to HIV-infected mothers, followed from 6 weeks of age for 24 months. Maternal and socioeconomic characteristics were recorded during pregnancy, data pertaining to the infant's birth were collected immediately after delivery, morbidity histories and anthropometric measurements were performed monthly. Multivariate Cox proportional hazards methods were used to assess the association between potential predictors and the time to first episode of stunting, wasting and underweight. A total of 2387 infants (54.0% male) were enrolled and followed for a median duration of 21.2 months. The respective prevalence of prematurity (<37 weeks) and low birth weight (<2500 g) was 15.2% and 7.0%; 11.3% of infants were HIV-positive at 6 weeks. Median time to first episode of stunting, wasting and underweight was 8.7, 7.2 and 7.0 months, respectively. Low maternal education, few household possessions, low infant birth weight, child HIV infection and male sex were all independent predictors of stunting, wasting and underweight. In addition, preterm infants were more likely to become wasted and underweight, whereas those with a low Apgar score at birth were more likely to become stunted. Interventions to improve maternal education and nutritional status, reduce mother-to-child transmission of HIV, and increase birth weight may lower the risk of undernutrition among children born to HIV-infected women

A Tale of CI Build Failures: An Open Source and a Financial Organization Perspective
No full textContinuous Integration (CI) and Continuous Delivery (CD) are widespread in both industrial and open-source software (OSS) projects. Recent research characterized build failures in CI and identified factors potentially correlated to them. However, most observations and findings of previous work are exclusively based on OSS projects or data from a single industrial organization. This paper provides a first attempt to compare the CI processes and occurrences of build failures in 349 Java OSS projects and 418 projects from a financial organization, ING Nederland. Through the analysis of 34,182 failing builds (26% of the total number of observed builds), we derived a taxonomy of failures that affect the observed CI processes. Using cluster analysis, we observed that in some cases OSS and ING projects share similar build failure patterns (e.g., few compilation failures as compared to frequent testing failures), while in other cases completely different patterns emerge. In short, we explain how OSS and ING CI processes exhibit commonalities, yet are substantially different in their design and in the failures they report.Accepted Author ManuscriptSoftware Engineerin
hapassoc: Software for Likelihood Inference of Trait Associations with SNP Haplotypes and Other Attributes
No full textComplex medical disorders, such as heart disease and diabetes, are thought to involve a number of genes which act in conjunction with lifestyle and environmental factors to increase disease susceptibility. Associations between complex traits and single nucleotide polymorphisms (SNPs) in candidate genomic regions can provide a useful tool for identifying genetic risk factors. However, analysis of trait associations with single SNPs ignores the potential for extra information from haplotypes, combinations of variants at multiple SNPs along a chromosome inherited from a parent. When haplotype-trait associations are of interest and haplotypes of individuals can be determined, generalized linear models (GLMs) may be used to investigate haplotype associations while adjusting for the effects of non-genetic cofactors or attributes. Unfortunately, haplotypes cannot always be determined cost-effectively when data is collected on unrelated subjects. Uncertain haplotypes may be inferred on the basis of data from single SNPs. However, subsequent analyses of risk factors must account for the resulting uncertainty in haplotype assignment in order to avoid potential errors in interpretation. To account for such uncertainty, we have developed hapassoc, software for R implementing a likelihood approach to inference of haplotype and non-genetic effects in GLMs of trait associations. We provide a description of the underlying statistical method and illustrate the use of hapassoc with examples that highlight the flexibility to specify dominant and recessive effects of genetic risk factors, a feature not shared by other software that restricts users to additive effects only. Additionally, hapassoc can accommodate missing SNP genotypes for limited numbers of subjects.
Cyberinfrastructure 2010 in the Rockies: a human centered approach
No full textPresented at the CI days: cyberinfrastructure in the Rockies - a human centered approach held on August 13, 2010, at Colorado State University, Fort Collins, Colorado. This conference brought together librarians, IT staff, and faculty members from institutions in Colorado to explore cyberinfrastructure needs in academic/research environments and the topic of "Open Access" to information as it contributes to the formation of effective cyberinfrastructure. Funded as part of the nation-wide Cyberinfrastructure days initiative, the event was Sponsored by the Colorado State University Libraries, Colorado State University Information Science and Technology Committee (ISTeC), and Colorado Alliance of Research Libraries.The presenter is affiliated with Internet 2, https://www.internet2.edu/
