This research explores microbial chain elongation as a pathway for production of complex organic compounds in soils with implication for the carbon cycle. In chain elongation, simple substrates such as ethanol and short chain carboxylates such as acetate can be converted to longer carbon chain carboxylates under anaerobic conditions through cyclic, reverse β oxidation. This pathway elongates the carboxylate by two carbons. The chain elongation process is overall thermodynamically feasible, and microorganisms gain energy through this process. There have been limited insights into the versatility of chain elongating substrates, understanding the chain elongating microbial community, and its importance in sequestering ...

La escritura de José Martí en sus primeros años como escritor y periodista se desenvuelve en una atmósfera política tan dinámica como el entorno cultural al que se expone a su llegada a México desde su experiencia diaspórica en España. Por ello, este estudio propone situar la etapa mexicana de Martí desde marzo de 1875 hasta diciembre de 1875 como un episodio clave en el desarrollo crítico de sus ideas centrales. Por lo tanto, esta investigación radica en el estudio de los elementos que participan en la formulación martiana en torno al concepto de cultura como síntoma de las nuevas ...

This work considers the design of separating input signals in order to discriminate among a finite number of uncertain nonlinear models. Each nonlinear model corresponds to a system operating mode, unobserved intents of other drivers or robots, or to fault types or attack strategies, etc., and the separating inputs are designed such that the output trajectories of all the nonlinear models are guaranteed to be distinguishable from each other under any realization of uncertainties in the initial condition, model discrepancies or noise. I propose a two-step approach. First, using an optimization-based approach, we over-approximate nonlinear dynamics by uncertain affine models, ...

Madness is disruptive. It doesn't play by the rules. Madness is influenced, created, and caused by many different factors; it can be at different times disorienting, debilitating, or a space of radical potential. In this thesis, I argue for the empowering potential of narrative and rewriting identity in the face of painful disruptions. I argue that the way that we conceptualize madness and how we internalize trauma affects how we reconfigure identity as an ongoing process and therefore whether and how we are able to embrace creative, diverse and dynamically empowered futures. I argue against positivist traditions of categorization and ...

The inspiration to undertake this pilot study came after observation and reflection by the clinician-researcher, a board-certified music therapist who has used the harp as the primary instrument when facilitating sessions, on hundreds of music therapy sessions that took place at a facility for behavioral health and chemical dependency. It was observed that the use of improvised harp music as a therapeutic intervention within the context of a music therapy session seemed to relax patients who reported that they were nervous or anxious, and it was also noted that following a listening exercise that consisted of improvised harp music, patients ...

Thermodynamic development and balance of plant study is completed for a 30 MW solar thermochemical water splitting process that generates hydrogen gas and electric power. The generalized thermodynamic model includes 23 components and 45 states. Quasi-steady state simulations are completed for design point system sizing, annual performance analysis and sensitivity analysis. Detailed consideration is given to water splitting reaction kinetics with governing equations generalized for use with any redox-active metal oxide material. Specific results for Ceria illustrate particle reduction in two solar receivers for target oxygen partial pressure of 10 Pa and particle temperature of 1773 K at a design ...

Prophylactic bilateral mastectomy (PBM) is the current recommended course of action for women with increased genetic risk for breast and ovarian cancer. Nevertheless, many receive negative feedback from family and friends surrounding the decision to undergo this surgery because they do not have cancer when the decision is made; this results in a limited support network for coping with their PBM. Low social support is associated with depression, negativity, and anxiety. Women who had a PBM, were currently undergoing or had completed reconstruction, and were in a committed romantic relationship at the time of the surgery were surveyed (N = ...

This dissertation is comprised three main sections including a journal article, book chapter and a policy reflection piece. My guiding research question is the following—How do Jemez Pueblo people and their descendants who migrated to California as a result of the Relocation Act of 1956 define their cultural identities? The journal article seeks to address the question: How can we explore the experiences of Urban Native Americans from a strengths-based approach, restructuring dominant narratives, and breaking barriers between urban and reservation spaces? Additionally, the journal article will provide a literature overview on urban American Indian experiences, including the stories of ...

Indigenous students have not been achieving their educational goals similar to other racial and ethnic groups. In 2008 Native American students completed a bachelor's degree at a rate of 38.3% the lowest rate of all racial and ethnic groups and lower than the national average of 57.2%. The high attrition rate of Native students in post-secondary education, nationally, suggests that on-going colonization may be to blame. Much of the research exploring retention strategies found culturally sensitive institutions, family and peer support, supportive relationships with faculty and staff, skill development, and financial aid knowledge were consistent factors for student retention. No ...

This study examined the factor structure of supervisee disclosure in clinical supervision. An original survey measure was created for this study, the Supervisee Disclosure Scale (SDS). Through exploratory factor analysis eight specific content areas of supervisee disclosure were identified. The eight specific content areas of supervisee disclosure include: Perceived Clinical Inadequacy, Transference Issues, Strengths of the Supervisory Relationship, Clinical Successes, Self, Weaknesses of the Supervisory Bond, Dissatisfaction with the Clinical Setting, and Own Clinical Voice. Furthermore, this study examined the potential relationship of clinical experience with the content areas of supervisee disclosure. The results of this study support a relationship ...
