An Autoethnograpy of a Baby Boomer in Higher Education: Challenges and Catalysts for Change
No full textHigher education as a baby boomer brings mental, physical, and economic adjustments, concerns, and insecurities. Additionally, life delivers unexpected challenges and barriers which can cause hardships requiring various types of motivation. Fortunately, there are also catalysts which can contribute toward successes. Literature from four major elements were the focus in this study: motivation, adult learning, challenges, barriers, and catalysts. Theorists and theories included Vroom’s expectancy theory of motivation with the added factor of cost, and Ryan and Deci’s theory on self-determination; Mezirow’s transformative learning and Knowles’s self-directed learning; Cross’s theory on educational barriers—situational, dispositional, and institutional; and Cobb’s social support theory. This research study is qualitative; specifically, evocative autoethnography. Data for analysis consisted of written narratives, white boards, posters, sketches, and verbal conversations. Sensemaking and memory work were utilized in reflective analysis. Through the autoethnographic process, I recognized the following salient themes: (1) this “do over” time was enabled by my owning the advantage of longevity in my encore years; (2) I was motivated in various ways, especially when my fears met my faith; (3) my higher educational experience that I have accomplished up and to this point was instigated and supported by Honey and influential others; and (4) the accretion through learning proved transformative. The purpose of this research study is intended to bring into focus, awareness, and understanding to the challenges being faced by baby boomers, adult learners and nontraditional students, as well as to the educational institutions of higher education and their administrators and faculties
Developmental morphology of galls induced by Diplolepis rosaefolii (Hymenoptera: Cynipidae) on the leaves of Rosa virginiana and the influence of Periclistus species on the D. rosaefolii galls
No full textThe larval stages of the cynipid wasp Diplolepis rosaefolii induce the formation of single-chambered lenticular galls on the leaves of the wild shrub rose, Rosa virginiana. The gall consists of four tissue layers which surround a centrally located larval chamber. These include an outermost dermal layer, underlying parenchyma, sclerenchyma, and nutritive tissue.Development in the D. rosaefolii galls involves a number of characteristics which are unique to this gall, and differ markedly from development in other Diplolepis galls studies. These characteristics include the presence of double sclerenchymal layers and the lack of vascularization in the gall wall. Periclistus is an inquiline in the galls induced by D. rosaefolii. Under the influence of Periclistus larvae, a number of morphological changes, including an increase in the number of larval chambers, were observed in the galls. Initially, a loss of D. rosaefolii-induced nutritive tissue is seen when Periclistus eggs are laid in the galls. Once the Periclistus larvae hatch, the number of cells which make up the parenchyma increases. Changes in tissue type, proportion, and overall morphology exhibited by Periclistus-modified galls were studied using conventional light microscopy techniques.Source: Masters Abstracts International, Volume: 36-06, page: 1530.Advisers: Glenda Wright; Christian Lacroix
