Exploring Generativity In Young Adults: A Grounded Theory Study, Addison Sellon
Exploring Generativity In Young Adults: A Grounded Theory Study, Addison Sellon
Department of Agricultural Leadership, Education and Communication: Dissertations, Theses, and Student Scholarship
Generativity expresses one’s level of care and concern for the next generation (Erikson, 1950, 1963). Initially established as a middle adulthood phenomenon, generativity has long been rooted in a middle adulthood framework both conceptually and through its psychometric dimensions. However, many studies have found generativity to be present in other stages of life, particularly young adulthood. This then raised the question of whether the traditional model used for generativity’s manifestation represents young adults’ experiences. This study sought further to explore generativity’s manifestation in a way that is specific to young adults. Applying traditional grounded theory techniques, the present research reanalyzed …
Larval Fish Abundance In The Benthic And Surface Drift Of The Missouri River, Ryan L. Ruskamp
Larval Fish Abundance In The Benthic And Surface Drift Of The Missouri River, Ryan L. Ruskamp
Department of Agricultural Leadership, Education and Communication: Dissertations, Theses, and Student Scholarship
Knowledge of the larval fish community of the Missouri River is one of the biggest gaps in fisheries research. The Nebraska Game and Parks Commission has sampled the drift of the Missouri River for many years (1983-2015), but these data have not been compiled into a unified assessment. Therefore, the objectives of this study were to: 1) quantify temporal and spatial aspects of larval fish community composition (richness) and structure (abundance) of the surface drift, 2) quantify associations of larval fish communities of the drift to different discharges of the Missouri River, 3) quantify the larval benthic drift community, and …
Student Mindset Compared To Performance On The Nebraska State Accountability Test, Ann E. Dvorak
Student Mindset Compared To Performance On The Nebraska State Accountability Test, Ann E. Dvorak
Department of Agricultural Leadership, Education and Communication: Dissertations, Theses, and Student Scholarship
Carol Dweck’s research on fixed vs. growth mindset has led to many opportunities for educational research. According to Dweck, a person with a fixed mindset believes that his or her qualities related to a certain task are unchangeable while an individual with a growth mindset believes that his or her qualities related to a certain task can be changed and improved (Dweck, 2006). A correlative study was conducted to identify relationships that exist between student mindset and scores from the Nebraska State Accountability Test (NeSA). For this study, students in the 7th, 8th, and 11th …
Characterization Of Chemotype And Aggressiveness Of Nebraska Isolates Of Fusarium Graminearum, Anita Panthi
Characterization Of Chemotype And Aggressiveness Of Nebraska Isolates Of Fusarium Graminearum, Anita Panthi
Department of Agricultural Leadership, Education and Communication: Dissertations, Theses, and Student Scholarship
Fusarium head blight (FHB), caused mainly by Fusarium graminearum, is a devastating disease of wheat and other small grain cereals. FHB lowers grain yield and quality and contaminates grain with mycotoxins, predominantly deoxynivalenol (DON) and its acetylated derivatives 3-ADON and 15-ADON. Forty one Fusarium isolates collected from grain elevators and wheat fields in Nebraska in 2009 and 2010 were sequenced for molecular identification. Forty isolates were identified as F. graminearum and one isolate was identified as F. culmorum. Seventy seven F. graminearum isolates collected from grain elevators and wheat fields in Nebraska from 2007 to 2010 were tested …
