Using Appreciative Inquiry as a Tool for Congregational Change
Successful navigation of congregational change is difficult. Churches face numerous technical and adaptive challenges. While leaders can often guide their churches through technical change with logic, negotiation and even force, adaptive change requires a deeper form of reprogramming and congregational discernment. The College Church of Christ, having been in decline for nearly two decades, went through an intensive process of appreciative inquiry to elicit data that might fund a new, life-giving narrative. This article discusses that process and challenges that arose in moving on to next steps
Crafting a Congregational Narrative for the College Church of Christ in Fresno, California
This thesis describes a ministry project in the College Church of Christ in Fresno, California. In this project I led the congregation through a narrative crafting process in order to clarify the church’s identity and increase its capacity for mission. In recent decades, the College Church moved away from some of its founding characteristics yet failed to clarify a new sense of identity. It subsequently had difficulty acting with a unified sense of purpose and instead moved increasingly toward fragmentation.
Data for crafting the new narrative came from three weeks of group interviews. My research team conducted these interviews in the church’s six adult classes, called shepherding groups. Well over half of all adults in the church responded during the sessions. The interviews consisted of a form of questioning called appreciative inquiry to elicit and build upon the positive memories and feelings about the past. I inserted the eschatological trajectory of Romans 8 into the process in hopes that the resulting narrative and congregational identity would be consonant with God’s unveiling plans for the world. I chose this passage as a significant representation of Paul’s theology and a crucial tool for shaping the church’s view of eschatology—two needed elements in this process. Repeating themes appeared in the group interviews, and I used these to assemble the narrative. In so doing, we reinterpreted the congregation’s history and injected a new appreciation for the mission of God. This thesis describes the project, shares the resultant narrative, and explains the results and potential implications of the project
A vertebrate case study of the quality of assemblies derived from next-generation sequences
The unparalleled efficiency of next-generation sequencing (NGS) has prompted widespread adoption, but significant problems remain in the use of NGS data for whole genome assembly. We explore the advantages and disadvantages of chicken genome assemblies generated using a variety of sequencing and assembly methodologies. NGS assemblies are equivalent in some ways to a Sanger-based assembly yet deficient in others. Nonetheless, these assemblies are sufficient for the identification of the majority of genes and can reveal novel sequences when compared to existing assembly references

Evaluating the contribution of rare variants to type 2 diabetes and related traits using pedigrees
Significance
Contributions of rare variants to common and complex traits such as type 2 diabetes (T2D) are difficult to measure. This paper describes our results from deep whole-genome analysis of large Mexican-American pedigrees to understand the role of rare-sequence variations in T2D and related traits through enriched allele counts in pedigrees. Our study design was well-powered to detect association of rare variants if rare variants with large effects collectively accounted for large portions of risk variability, but our results did not identify such variants in this sample. We further quantified the contributions of common and rare variants in gene expression profiles and concluded that rare expression quantitative trait loci explain a substantive, but minor, portion of expression heritability.</jats:p
A new strategy for enhancing imputation quality of rare variants from next-generation sequencing data via combining SNP and exome chip data
Background: Rare variants have gathered increasing attention as a possible alternative source of missing heritability. Since next generation sequencing technology is not yet cost-effective for large-scale genomic studies, a widely used alternative approach is imputation. However, the imputation approach may be limited by the low accuracy of the imputed rare variants. To improve imputation accuracy of rare variants, various approaches have been suggested, including increasing the sample size of the reference panel, using sequencing data from study-specific samples (i.e., specific populations), and using local reference panels by genotyping or sequencing a subset of study samples. While these approaches mainly utilize reference panels, imputation accuracy of rare variants can also be increased by using exome chips containing rare variants. The exome chip contains 250 K rare variants selected from the discovered variants of about 12,000 sequenced samples. If exome chip data are available for previously genotyped samples, the combined approach using a genotype panel of merged data, including exome chips and SNP chips, should increase the imputation accuracy of rare variants. Results: In this study, we describe a combined imputation which uses both exome chip and SNP chip data simultaneously as a genotype panel. The effectiveness and performance of the combined approach was demonstrated using a reference panel of 848 samples constructed using exome sequencing data from the T2D-GENES consortium and 5,349 sample genotype panels consisting of an exome chip and SNP chip. As a result, the combined approach increased imputation quality up to 11 %, and genomic coverage for rare variants up to 117.7 % (MAF < 1 %), compared to imputation using the SNP chip alone. Also, we investigated the systematic effect of reference panels on imputation quality using five reference panels and three genotype panels. The best performing approach was the combination of the study specific reference panel and the genotype panel of combined data. Conclusions: Our study demonstrates that combined datasets, including SNP chips and exome chips, enhances both the imputation quality and genomic coverage of rare variants
