This case study used ethnographic data collection tools to focus on the educational models and approaches used by the Tall Pines Quilt Guild (TPQG) in Huntsville, Texas. In this study I strove to explore the transfer of quiltmaking knowledge in a community-based art education organization, a quilt guild, and how those educational methods and models could be adapted to the museum setting. I became a member of the Guild and took on the research role of a participant observer to witness how the TPQG perpetuates the quilting craft for its members. Through observing various Guild events, such as monthly meetings, workshops, and bees I found the members frequently participated in cooperative and collaborative social learning. The rationale for undertaking this study was that there are many publications on how to make quilts, the history of quilt patterns, indexes of quilt patterns, quiltmakers' stories, quilt research, and quilt exhibition catalogues. However, proper documentation of the educational approaches used by women in quilt guilds has not been researched. Quilt guilds provide an environment where adults can learn and expand their knowledge about the quilting craft in the form of lifelong learning. By looking into how the Tall Pines Quilt Guild acts a community-based art education organization, the identified educational models used by quilt guilds could be employed at museums displaying quilt exhibits with potential program models and characteristics to inform the public about quilts, quiltmaking, and quilters. / text

I assessed the paleoclimatic significance of SD values of pition pine (Pinus edulis and P. monophylla) cellulose nitrate (cn) by developing, testing and applying deterministic and empirical models, in the context of the soil-plant-atmosphere continuum. Stable isotope values of precipitation, soil water, xylem sap, leaf water, atmospheric vapor, annual and sub-annual samples of tree-ring and needle cellulose, and climatic parameters, were measured along a gradient of decreasing summer rain in the southwestern U.S. Stable isotope composition of sap indicated depth of moisture extraction. Over the growing season in New Mexico and Arizona, where monsoon rains are important, trees shifted their water use to shallower depths. In Nevada, where summer rain is scarce, trees shifted to deeper moisture late in the growing season. Evaporation altered δD and δ¹⁸O values of precipitation inputs to soil. Only after heavy monsoons did soil water and sap isotopically resemble recent precipitation. Average precipitation δD values set the baseline for δD(cn). values at each site, but interannual variations in relative humidity and precipitation amount altered wood and leaf δD(cn) values, via leaf water effects. Leaf water (1w) was evaporatively enriched by seasonal moisture stress. δD(1w). and δ¹⁸O(1w) values were strongly correlated with relative humidity on a seasonal basis, but not on a diurnal basis. Measured δ¹⁸O(1w) values fit a steady-state model, with an offset attributable to relative humidity. Measured δD(1w) values were more depleted than predicted by the model, suggesting leaf water - organic matter isotopic exchange. Biochemical fractionation (ε(B)) of hydrogen isotopes between leaf water and cellulose was inversely correlated with relative humidity. Empirical models based on linear regressions demostrated significant correlations between δD(en) values and precipitation seasonality. An El Nirio-Southern Oscillation signal (wood δD(en) values inversely related to winter precipitation amount) was found in New Mexico and Arizona. A summer rain signal (leaf δD(en) values inversely related to summer humidity) was found at all sites. δD(en) values of pirion needles in packrat middens from Sevilleta LTER, New Mexico, suggest that late Pleistocene summers were as wet as today's, and/or that storm tracks could have shifted, bringing in more tropical moisture than currently.
