    Building a Cohesive Classroom: The effects of music on cooperation and community in a public, lower elementary, Montessori classroom

    The following research assesses how the daily integration of singing and listening to music helps to construct a socially cohesive, cooperative and joyful classroom during clean up time. This study combined group singing opportunities, a music listening station and music played during clean up time. The songs used for this study included lyrical themes of cooperation, happiness, overcoming obstacles and/or friendship. The thirty-day study involved twenty-one participants between the ages of six and nine at a public, Montessori school in Missouri. Each individual completed a pre- and post-survey, as well as a survey each time they used the music listening station. During clean up time, observations were taken daily to record instances of helpful behaviors and joy amongst the participants. Results of the surveys showed that the intervention was successful at increasing positive experiences during clean up time and including a Music Listening Station as an available work choice. The intervention was not successful in creating positive experiences when singing together as a group. Further research may include the use of other mediums to promote community and collaboration like the fine arts, sports or other group oriented activities

    Insight into Translational Activation in Yeast Mitochondria

    Mitochondrial function depends on over a thousand proteins, of which the majority are nuclear DNA-encoded and approximately one percent are mitochondrial DNA-encoded. The mitochondrial DNA of Saccharomyces cerevisiae contains eight protein-encoding genes, seven of which are required for proper function of the respiratory complexes and one encodes a ribosomal protein. The bigenomic nature of the oxidative phosphorylation complexes requires coordinated expression and regulation from both the nuclear and the mitochondrial genomes. It is currently unclear how this regulatory network operates. However, it is thought that nuclear genome-encoded messengers localized to the mitochondria aid in this coordination. A family of proteins termed mitochondrial translational activators has been shown to control the expression of all mitochondrial-encoded protein genes in a gene-specific manner. Evidently, each mitochondrial mRNA is regulated by a specific protein or a subset of proteins that permits translation of that transcript. If these factors are absent, there will be no synthesis of the polypeptide, leading to a respiratory deficient cell. Although a functional link between translational activators and the mitochondrial genes they control has long been established genetically, the activation mechanism is entirely unknown. This study focuses on the mechanism of activation of two representative members of this translational activator family, Pet111p and Cbp1p. These activators are required for the expression of COX2 and COB, respectively. Translational activators have been shown to have multiple functions including, transcript stabilization and mRNA localization to the membrane, as well as to the translation machinery. Current genetic data suggests that both Pet111p and Cbp1p interact with RNA targets in the 5′-untranslated regions of COX2 and COB, respectively. However, neither the identity of these sites, nor has the ability of these proteins to interact with RNA ever been demonstrated. The objective of this study is to characterize the functional mechanism of translational activation for both Pet111p and Cbp1p and ultimately learn how they aid in the coordination of dual-genomic expression

    The Usefulness of Neutrality

    Recently, the idea of therapeutic neutrality has been attacked. Many observers have suggested that the neutral therapist is inhuman and unempathic. Actually, being a neutral therapist means being especially human and empathic. The neutral therapist\u27s empathic contact with the patient is the most extensive in that it includes not only contact with feelings and thoughts of which the patient is aware, but also contact with all those intolerable thoughts and feelings of which the patient prefers to be unaware. Such awareness in the therapist is possible only when the therapist remains, as Anna Freud (I) recommends, equidistant from the patient\u27s id, ego and superego, that is equidistant from the forces generating the patient\u27s psychic conflict. Such objectivity does not preclude warmth, rather it directly evolves from warm and authentic contact with the patient

    Spacecraft Coatings Optimizing LiDAR Debris Tracking and Light Pollution Impacts

    Space safety and astronomy are at odds. The problem posed by space debris and derelict satellites in the low Earth orbit is an existential threat to all space operations. These dangerous objects in space are more easily tracked with ground-based LiDAR if they are highly reflective, especially in the near-infrared (NIR) range. At the same time, reflective objects in orbit are the bane of ground-based astronomers, causing light pollution and marring images with bright streaks. How can this tension be resolved? The hypothesis tested is that a near-infrared-transparent (NIRT) coating which is opaque in the visible light range and transparent in the NIR range is a promising candidate for use in satellite construction. This experiment tests whether typical spacecraft surfaces such as anodized aluminum or multi-layer insulation (MLI) with a NIRT coating applied will absorb visible light and reflect NIR. The findings confirm the efficacy of the NIRT coating for this purpose, reducing visible light reflection by 47% (+/-3%) and increasing reflection in the NIR by 7% (+/-2%). This promising novel NIRT coating may help provide a path forward to resolve the tension between astronomy and the space industry
