Establishing Recharge Rates In The High Plains Aquifer: Mapping, Precipitation Modeling, And An Evaluation Of The Chloride Mass-Balance Method, Arindam Mukherjee

Electronic Theses and Dissertations

In this dissertation, three studies related to understanding and predicting recharge are presented. First, geospatial techniques were used to identify potential groundwater recharge areas in the High Plains Aquifer. Second, a precipitation generator was developed to produce site specific synthetic precipitation series that depend on daily precipitation occurrences, particularly on the distribution of wet spells for sites to be used in numerical modeling. Third, the unsaturated flow code VS2DI was modified to allow the simulation of chloride accumulation from recharge, and this model was used to evaluate errors in the Chloride-Mass-Balance (CMB) method for estimating recharge due to heterogeneity.

However, much is unknown about how the active site and secondary/tertiary-sphere interactions in these enzymes determine their function. De novo protein design enables the creation of simpler model systems that closely resemble the structure and function of native enzymes. Using de novo protein …

A Qualitative Examination Of The Interplay Of Attachment Styles, The Supervisory Relationship & Counseling Self-Efficacy, Kamiron Ball Tran

Electronic Theses and Dissertations

This phenomenological qualitative study explores the intricate dynamics between attachment styles, the supervisory relationship, and counseling self-efficacy among supervisory dyads in counseling. The findings reveal five themes: supervision is relational, supervision is a therapeutic space, security within supervision bolsters self-efficacy, supervision is a mirror for clinical practice, and the nuanced "both/and" nature of attachment and self-efficacy dynamics. This study addresses a gap in the literature by offering qualitative insights into the interplay of attachment styles, supervisory relationship, and counselor self-efficacy, thus contributing to a deeper understanding of the complexities within supervisory practices in counseling.

The Value Of Empathy For Teachers In Nontraditional Classrooms, Mindy Clair Waldrop

Electronic Theses and Dissertations

Little is known about the experience of teachers in nontraditional classrooms, particularly those in Juvenile Detention Centers (JDCs).
