Description
Within recent years, metal-organic frameworks, or MOF’s, have gained a lot of attention in the materials research community. These micro-porous materials are constructed of a metal oxide core and organic linkers, and have a wide-variety of applications due to their extensive material characteristic possibilities. The focus of this study is the MOF-5 material, specifically its chemical stability in air. The MOF-5 material has a large pore size of 8 Å, and aperture sizes of 15 and 12 Å. The pore size, pore functionality, and physically stable structure makes MOF-5 a desirable material. MOF-5 holds applications in gas/liquid separation, catalysis, and gas storage. The main problem with the MOF-5 material, however, is its instability in atmospheric air. This inherent instability is due to the water in air binding to the zinc-oxide core, effectively changing the material and its structure. Because of this material weakness, the MOF-5 material is difficult to be utilized in industrial applications. Through the research efforts proposed by this study, the stability of the MOF-5 powder and membrane were studied. MOF-5 powder and a MOF-5 membrane were synthesized and characterized using XRD analysis. In an attempt to improve the stability of MOF-5 in air, methyl groups were added to the organic linker in order to hinder the interaction of water with the Zn4O core. This was done by replacing the terepthalic acid organic linker with 2,5-dimethyl terephthalic acid in the powder and membrane synthesis steps. The methyl-modified MOF-5 powder was found to be stable after several days of exposure to air while the MOF-5 powder exhibited significant crystalline change. The methyl-modified membrane was found to be unstable when synthesized using the same procedure as the MOF-5 membrane.

Description
The goal of this research is to answer the questions 1) What is innovation? 2) Why is innovation important? 3) How does leadership impact the effectiveness in driving innovation? 4) How can insight be taught to other individuals who would like to drive innovation in their own practice? By defining leadership characteristics, actions, and attributes, a tangible framework was created which can be utilized by any leader as a guiding point to drive innovation. Data for this project was collected through two channels: a survey which was administered to individuals who identified primarily as undergraduates and professionals, then interviews were conducted with individuals who are recognized as innovative leaders. Interview participants were selected based on recommendations from peers, awards, and accolades received. The questions in the survey focused on collecting data on the general perception and understanding of what an innovative leader is compared to traditional change management elements. Interview questions honed in on specific information regarding leadership approaches, group dynamic techniques, and personal characteristics in relation to leadership style. The findings from the study can be used for positive impact on universities and organizations.

Description
Affect signals what humans care about and is involved in rational decision-making and action selection. Many technologies may be improved by the capability to recognize human affect and to respond adaptively by appropriately modifying their operation. This capability, named affect-driven self-adaptation, benefits systems as diverse as learning environments, healthcare applications, and video games, and indeed has the potential to improve systems that interact intimately with users across all sectors of society. The main challenge is that existing approaches to advancing affect-driven self-adaptive systems typically limit their applicability by supporting the creation of one-of-a-kind systems with hard-wired affect recognition and self-adaptation capabilities, which are brittle, costly to change, and difficult to reuse. A solution to this limitation is to leverage the development of affect-driven self-adaptive systems with a manufacturing vision.
This dissertation demonstrates how using a software product line paradigm can jumpstart the development of affect-driven self-adaptive systems with that manufacturing vision. Applying a software product line approach to the affect-driven self-adaptive domain provides a comprehensive, flexible and reusable infrastructure of components with mechanisms to monitor a user’s affect and his/her contextual interaction with a system, to detect opportunities for improvements, to select a course of action, and to effect changes. It also provides a domain-specific architecture and well-documented process guidelines, which facilitate an understanding of the organization of affect-driven self-adaptive systems and their implementation by systematically customizing the infrastructure to effectively address the particular requirements of specific systems.
The software product line approach is evaluated by applying it in the development of learning environments and video games that demonstrate the significant potential of the solution, across diverse development scenarios and applications.
The key contributions of this work include extending self-adaptive system modeling, implementing a reusable infrastructure, and leveraging the use of patterns to exploit the commonalities between systems in the affect-driven self-adaptation domain.

Description
This thesis project utilizes four frames created by Bolman and Deal’s book, Reframing Organizations to take a look at the Young Single Adults of the Church of Jesus Christ of Latter-Day Saints. The thesis begins by presenting the Church of Jesus Christ of Latter-Day Saints in the bigger picture of religion in the world and narrows down into the particular branch of the church centered on the Young Single Adults who are made up of unmarried 18-31 year olds. From there, opportunities for improvement within the Young Single Adult wards and stakes are mentioned. Then using the four frameworks from Bolman and Deal and outside research an analysis of the YSA is conducted, followed by potential solutions to the challenges and the opportunities for improvement within the Young Single Adults are discussed. The thesis is then concluded with any limitations and a final push for the implementation of these changes.
