MBTI Personality Types and Preferred Relationship Disengagement Strategies in Intimate Situations

This thesis poses two research questions that focus on MBTI personality types and specific strategies used to disengage romantic intimate heterosexual relationships. 1) Would one specific MBTI personality type prefer to use one dominate strategy to disengage a relationship? 2) Would any relationship situation yield one dominate strategy to disengage a relationship? A total of 116 college students were surveyed at a small Midwestern university. Age ranged from 18 years to 55 years with a mean age of 23.6 years. The experimental method consisted of administering Form G of the MBTI and an additional questionnaire measuring relationship strategies. The t-test for simple effects found significance between MBTI types and strategy selected to dissolve relationships at the (.05) level. Significant results were also found for type of situation and strategy selection at the (.05) level. The conclusions of this study found that certain MBTI personality types prefer to disengage relationships by using specific types of strategies. Situations were also found to be significant

The Texas Cesium Iodide Array for Astrophysical Measurements

A novel cesium iodide detector array as been designed for use at the Cyclotron Institute at Texas A&M University (TAMU). Officially named “The Texas Cesium Iodide Array for Astrophysical Measurements,” or TexCAAM, its design is intended for use in sub-Coulomb, alpha-transfer astrophysical experiments. Specifically, TexCAAM was designed to collect data in experiments that offer potential solutions to the Cosmological Lithium Discrepancy, as well as experimental observations of processes that could contribute to the formulation of zero metallicity, population-III stars in the early Universe. TexCAAM consists of 32 thallium-doped, cesium iodide scintillation detectors that are arranged to surround a mounted target. Its design has high geometric efficiency, possessing a solid angle coverage of ~90%. To reduce noise, TexCAAM was designed with a mounted 1500-um silicon charged-particle detector that functions as a coincidence gate. Rare isotope beams are available at the TAMU Cyclotron Institute using the Momentum Achromat Recoil Separator. As an efficient gamma spectrometer, TexCAAM can be used to fully characterize the reactions between a beam and a target material. TexCAAM’s construction is complete, and it has undergone energy calibrations for each of its constituent detectors. The efficiency calibration for the array is also complete for low energy gamma rays (< 1.5-2 MeV). TexCAAM has already been used successfully in several nuclear astrophysical experiments, and final calibrations are currently being conducted to characterize the detector setup for higher energy gamma rays. The physics and methodology for the apparatus characterization are presented in this thesis

Impact of Serving as an Extension Camping Instructor on Life Skills Development.

The purpose of this study was to determine if West Virginia University Extension Camping Instructors were influencing the life skill development of 4-H youth while also developing life skills of their own. This study utilized the unique perceptions of Extension Camping Instructors who were employed from the summer of 2007 to October of 2015 by examining their current level of life skills, how they felt being employed as an Extension Camping Instructor influenced the development of each skill, and how they felt their role impacted the life skill development of 4-H youth with whom they had worked. A descriptive survey was sent to each member of the target population who were employed during the designated time. The Extension Camping Instructor experience was perceived to have the greatest influence on leadership, community service/volunteering, problem solving, and communication among the target population while the Extension Camping Instructors perceive that their role has the greatest influence on teamwork, self-esteem, and community service/volunteer life skill development among 4-H youth. Adaptability, communication, and working with others who are different were rated as the most valued life skills learned through being an Extension Camping Instructor

Reaching Beyond the State: Judicial Independence, the Inter-American Court of Human Rights and Accountability in Guatemala

The authors examine the role of the Inter-American Court of Human Rights in its efforts to impose accountability for human rights violations in Latin America. They suggest that because domestic enforcement mechanisms are irreconcilably deficient in this task, accountability must emanate from beyond the state. They test this contention by examining one of the most challenging nations in the region – Guatemala

Calix 2007:9th International Conference on Calixarene Chemistry

The DOE funds helped support an International Conference, Calix 2007, whose focus was on Supramolecular Chemistry. The conference was held at the University of Maryland from August 6-9, 2007 (Figure 1). The conference website is at www.chem.umd.edu/Conferences/Calix2007. This biannual conference had previously been held in the Czech Republic (2005), Canada (2003), Netherlands (2001), Australia (1999), Italy (1997), USA (Fort Worth, 1995) Japan (1993) and Germany (1991). Calixarenes are cup-shaped compounds that are a major part of Supramolecular Chemistry, for which Cram, Lehn and Pederson were awarded a Nobel Prize 20 years ago. Calixarene chemistry has expanded greatly in the last 2 decades, as these compounds are used in synthetic and mechanistic chemistry, separations science, materials science, nanoscience and biological chemistry. The organizing committee was quite happy that Calix 2007 encompassed the broad scope and interdisciplinary nature of the field. Our goal was to bring together leading scientists interested in calixarenes, molecular recognition, nanoscience and supramolecular chemistry. We believe that new research directions and collaborations resulted from an exchange of ideas between conferees. This grant from the DOE was crucial toward achieving that goal, as the funds helped cover some of the registration and accommodations costs for the speakers

Non-covalent (iso)guanosine-based ionophores for alkali(ne earth) cations

Different (iso)guanosine-based self-assembled ionophores give distinctly different results in extraction experiments with alkali(ne earth) cations. A lipophilic guanosine derivative gives good extraction results for K+, Rb+, Ca2+, Sr2+, and Ba2+ and in competition experiments it clearly favors the divalent Sr2+ (and Ba2+) cations. 1,3-Alternate calix[4]arene tetraguanosine hardly shows any improvement in the extraction percentages compared to its reference compound 1,3-alternate calix[4]arene tetraamide. This indicates that one G-quartet does not provide efficient cation complexation under these conditions. In the case of the lipophilic isoguanosine derivative there is a cation size dependent affinity for the monovalent cations (Cs+ Rb+ K+), but not for the divalent cations (Ca2+ > Ba2+ > Sr2+ > Mg2+). In competition experiments the isoguanosine derivative, unlike guanosine, does not discriminate between monovalent and divalent cations, giving an almost equal extraction of Cs+ and Ba2+.\ud \u

Flaming dormant alfalfa for pest control

Alfalfa (Medicago sativa Leyss) is an important forage crop whose production is hampered by pests, including the alfalfa weevil (Hypera postica Gyllenhal) which is a major problem in many areas. Flaming during dormancy could be an alternative control measure. Late fall and early spring flaming at three intensities were compared with pesticide and no treatment for their effects on alfalfa weevil damage and weed density. In four site-years, flaming at high intensity generally reduced weevil damage to alfalfa. When winter annual broadleaf weeds were prevalent, flaming decreased their density. When fall and spring flaming effects were different, spring flaming gave better results

Investigation of nanodispersion in polystyrene-montmorillonite nanocomposites by solid state NMR

Nanocomposites result from combinations of materials with vastly different properties in the nanometer scale. These materials exhibit many unique properties such as improved thermal stability, reduced flammability, and improved mechanical properties. Many of the properties associated with polymer–clay nanocomposites are a function of the extent of exfoliation of the individual clay sheets or the quality of the nanodispersion. This work demonstrates that solid-state NMR can be used to characterize, quantitatively, the nanodispersion of variously modified montmorillonite (MMT) clays in polystyrene (PS) matrices. The direct influence of the paramagnetic Fe3, embedded in the aluminosilicate layers of MMT, on polymer protons within about 1 nm from the clay surfaces creates relaxation sources, which, via spin diffusion, significantly shorten the overall proton longitudinal relaxation time (T1 H). Deoxygenated samples were used to avoid the particularly strong contribution to the T1 H of PS from paramagnetic molecular oxygen. We used T1 H as an indicator of the nanodispersion of the clay in PS. This approach correlated reasonably well with X-ray diffraction and transmission electron microscopy (TEM) data. A model for interpreting the saturation-recovery data is proposed such that two parameters relating to the dispersion can be extracted. The first parameter, f, is the fraction of the potentially available clay surface that has been transformed into polymer–clay interfaces. The second parameter is a relative measure of the homogeneity of the dispersion of these actual polymer–clay interfaces. Finally, a quick assay of T1 H is reported for samples equilibrated with atmospheric oxygen. Included are these samples as well as 28 PS/MMT nanocomposite samples prepared by extrusion. These measurements are related to the development of highthroughput characterization techniques. This approach gives qualitative indications about dispersion; however, the more time-consuming analysis, of a few deoxygenated samples from this latter set, offers significantly greater insight into the clay dispersion. A second, probably superior, rapid-analysis method, applicable to oxygen-containing samples, is also demonstrated that should yield a reasonable estimate of the f parameter. Thus, for PS/MMT nanocomposites, one has the choice of a less complete NMR assay of dispersion that is significantly faster than TEM analysis, versus a slower and more complete NMR analysis with sample times comparable to TEM, information rivaling that of TEM, and a substantial advantage that this is a bulk characterization method. © 2003 Wiley Periodicals, Inc.* J Polym Sci Part B: Polym Phys 41: 3188–3213, 200
