The answers are hiding within the parallels of my questions
(Wichita State University, 2012-04-03) Sippel, Emily
Parallels between my questions appear clearly, but I am always looking for points of intersection. Being centered in a world of inevitable, continuous change provokes many constant battles not only amongst opposing forces and individuals, but within each of our own complicated, intrapersonal relationships as well. Essentially, we must accept the reality that change is beyond our control. Knowing and understanding what we have to work with, whether it’s our internal congeries or tangible objects, allows us to find a solution. By effectively rearranging this information and applying it in novel ways to the aversive situation, we adapt. How much control do we really have? With necessary mental modifications, a sense of control over one’s self is the beginning that is rife with possibilities of what outcomes can be created. I create my sculptures as a physical means of experimenting with this understanding. Fortunately, control over the artwork always becomes shared between the medium and me. This enables me to constantly grow and learn by patiently changing through creative problem solving, leading to an improved outcome that is unique and inimitable (the strange goal of every human being.) Using art as a tool for knowledge helps me to draw parallels between the world I create and the world within which I live. I offer one interpretation of these spheres and my views on where humanity stands by navigating the space between these dichotomies in my work. There is no black and white anymore, and finding equilibrium, that middle-point of balance, is a constant process of life. We could dissolve into a world of gray or fall into the middle where true color exists. I choose to be consumed by the latter.
Lower lip and jaw speed capacity of young, middle-aged, and older adults
(Wichita State University, 2012-04-03) Sanderson, Ali
Although it is well documented that speech and swallowing function decline with age, the underlying reasons are only poorly understood. Motor performance decline has been commonly discussed as a contributing factor; however, studies on orofacial motor capacities are rare. Aging research on limbs has shown movement speed declines with age; however, cranial muscles differ in many ways from skeletal muscles. The limbs may, therefore, not serve as a good model to predict changes in the orofacial system. To address the current knowledge gap, the current study sought to determine aging effects on orofacial motor capacity. This study included 36 participants in the following age groups: 20-27, 45-55, and 65-74. Lower lip and jaw movements were captured using a motion capture system. Reflective markers were placed on on the jaw, lower lip, and forehead. All participants completed metronome paced fixed-target tasks, a task specifically designed to experimentally control the duration and excursion of the movements. Metronome paces ranged from 1.4 Hz (slow) to 6.7 Hz (very fast). The 3D Euclidean distance signal between the center lower lip marker or the left jaw marker and the left bottom head marker were used to calculate peak speeds at each metronome pace. Elicited peak speeds were compared across age groups to determine aging effects on speed capacity. Kinematic findings suggested that jaw and lower lip speed capacity does not decline with age. Findings were discussed with regards to limb motor performance in older adults, as well as reported declines in speech production.
Characterization of recombinant hFSH glycosylation
(Wichita State University, 2012-04-03) Rose, Emily; White, William K.
Human FSH stimulates ovarian follicle development in females and regulates testicular Sertoli cell function in males. Our laboratory has identified two major hFSH forms differing in glycosylation and binding affinity to FSH receptors. The larger hFSH glycoform possesses all 4 N-glycans (tetra-glycosylated hFSH). The smaller glycoform consists of non-glycosylated FSHβ subunit combined with glycosylated α subunit (di-glycosylated hFSH). As FSH glycosylation is essential for FSH receptor activation, this difference in glycosylation could affect activation of intracellular signal pathways. Currently, we express recombinant human FSH in stably transfected GH3 rat anterior pituitary somatotrope cells. The goal of the present study is to compare recombinant hFSH glycosylation with human pituitary-derived FSH glycosylation. FSH preparations immunopurified from conditioned medium and separated into high and low MW fractions by gel filtration were evaluated. Goals included verifying the presence of both glycoforms and defining the nature of the glycan populations decorating each glycoform. Reverse-phase, high performance liquid chromatography carried out on high and low MW recombinant hFSH fractions revealed both factions possessed mostly the tetra-glycosylated glycoform. Total amino acid and carbohydrate analysis indicated the glycan populations were largely bi-antennary, while human pituitary FSH possesses predominantly tri- and tetra-antennary N-glycans. The smaller recombinant hFSH glycans may explain why the two hFSHβ bands in these preparations corresponding to pituitary hFSH 21 and 24 kDa bands migrate faster than those derived from pituitary hFSH.
A world apart: bullying in a middle school culture
(Wichita State University, 2012-04-03) Rodriguez, Rebecca
As adolescents have peer-to-peer contacts, the perceptions and lived experiences of healthy inter-personal relationships vary between adults, including parents and educators, and the youths themselves. Relational discrepancy inhibits the development of an appropriate understanding of the parameters of healthy interactions. Current research indicates that youths are susceptible to bullying; therefore, an effort is needed to support bullying prevention strategies as a means of combating inter-personal relationship violence and abuse. Additionally, effective communication is needed to illustrate acceptable behaviors. The issue of bullying will best be examined using an extended literature review and quantitative research. The research – which is a segment of a large, long-term research grant – uses student questionnaires to examine behavior within the students’ school culture. This research focused on eleven- to fourteen-year-olds in the 6th, 7th, and 8th grades at Hadley Middle School, a public school in the Midwestern metropolitan city of Wichita, Kansas. Throughout two academic years, students completed questionnaires that asked them to assess respectful behaviors in their school culture. This information will be used to develop tools needed for schools to implement policy changes that equip adolescents entering into inter-personal relationships with a clearer understanding of healthy behaviors.
