A Year\u27s Time
In lieu of an abstract, below is the essay\u27s first paragraph.
A LOT CAN happen given a year\u27s time: birthdays, anniversaries, holidays, memorials, deaths. One year can bring forth many changes to a person\u27s life. Seasons come and they go. Spring to summer, summer to fall, fall to winter, winter to spring, and so on. The seasons will continue to go on in continuous repetition . .
Application of an Ultrasonic Sensor to Monitor Soil Erosion and Deposition
While erosion and deposition are naturally occurring processes, these processes can be accelerated by human influences. The acceleration of erosion causes damage to human assets and costs billions of dollars to mitigate. Monitoring erosion at high resolutions can provide researchers and managers the data necessary to help manage erosion. Current erosion monitoring methods tend to be invasive to the area, record low frequency measurements, have a narrow spatial range of measurement, or are very expensive. There is a need for an affordable monitoring system capable of monitoring erosion and deposition non-invasively at a high resolution. The objectives of this research were to (1) design and construct a non-invasive sediment monitoring system (SMS) using an ultrasonic sensor capable of monitoring erosion and deposition continuously, (2) test the system in the lab and field, (3) and determine the applications and limitations of the system. The ultrasonic sensor measures the time of reflectance of sound waves to calculate the distance to the area non-invasively. The SMS was tested in the lab to determine the extent to which the soil type, slope, surface topography, change in distance and vegetation impact the SMS’s ultrasonic sensor’s measurement. It was found that the soil type, slope and surface topography had little effect on the measurement, but the change in distance of the measurement and the introduction of vegetation impacted the measurement. The error in measurement increased as the sensing distance increased, and vegetation interferes with the measurement. In the field during high flows, as erosion and deposition occur, the changes in distance were determined in near real-time, allowing for the calculation of erosion and deposition quantities. The system was deployed to monitor deposition on sandy streambanks in the Nebraska Sandhills and erosion on a streambank and field plot in Lincoln, Nebraska. The system was proven successful in measuring sediment change during high flow events but yielded some error; ±1.06 mm in controlled lab settings and ±10.79 mm when subjected to environmental factors such as temperature, relative humidity and wind.

Challenges and solutions for autism in academic geosciences
Researcher diversity promotes research excellence. But academia is widely perceived as inaccessible to those who work in non-stereotypical ways, and disabled researchers are consequently chronically under-represented within higher education. The barriers that academia presents to the inclusion and success of disabled individuals must therefore be understood and removed in order to enhance researcher diversity and improve the quality and quantity of research. Autism is a disability that is particularly under-represented within higher education, despite many autistic individuals having attributes that are conducive to research excellence. With a focus on geosciences, we use the experiences of an autistic PhD student to evaluate why academia can be inaccessible, and propose simple strategies that can reduce and remove barriers to academic success. We suggest that minor changes to communication, the academic environment and better disability awareness can make significant differences to the inclusion of disabled researchers, particularly those with autism. These changes would also benefit the wider scientific community and promote research and teaching excellence
BOHMs AWAY! Lessons from a Collection Survey
VCU James Branch Cabell Library underwent a major renovation and expansion from 2014 to 2016, necessitating a move of all special collections and archives materials. After the move we surveyed our collections to help us regain intellectual and physical control. In addition, the survey allowed us to assess whether collections were in need of additional processing or reprocessing to make them more accessible physically and intellectually, identify special formats, and address conservation issues.
To conduct the survey, we created a form and used this in conjunction with the assessment tool in Archivists’ Toolkit. The form included checklists to note information such as material formats other than paper, specific condition and preservation issues, as well as a general notes field. For brevity and consistency, we created a list of abbreviations to use. Collections were ranked using an agreed upon set of criteria in multiple categories. The rankings have helped determine which collections are in most need of attention.
During the course of the survey we discovered that not all collections were processed equally, meaning that they didn’t always conform to best practices and standards. This poster will expand upon what we learned and what we’re doing with the information we obtained
Mental Health Comorbidities in Adolescents with ASD: Indirect Effects of Family Functioning through Youth Social Competence
Mental Health Comorbidities in Adolescents with ASD: Indirect Effects of Family Functioning through Youth Social Competence

Recent research has established the high comorbidities of mental health problems in adolescents with Autism Spectrum Disorder (ASD; see Strang, et al., 2012), prompting researchers to examine factors that may contribute to elevated anxiety and depression. Given the centrality during adolescence of both the family and peer contexts (Greenlee, Winter, & Diehl, 2018) as well as the stage salience of peer relationships (Masten et al., 1995), this study focused on family functioning, social competence, and mental health in verbally-fluent adolescents with ASD. Some have suggested that adolescents with ASD who have no cognitive impairment are more interested in social interaction but also more aware of their social differences (Mazurek & Kanne, 2010). Combined with the social demands of adolescence, increased social awareness may put youth at risk for disengaging from peers; poor peer relationships, feelings of isolation, and loneliness have been associated with internalizing problems in youth with ASD (Bauminger & Kasari, 2000; Vickerstaff et al., 2007; Whitehouse et al., 2009). We reasoned that adolescents learn social skills in part from family experiences, even in the context of ASD, and that the family environment plays a role in adolescent’s social competence. Thus, while social-communication deficits are an inherent part of an ASD diagnosis, families still play a role in adolescents’ social competencies and influence their social development. Therefore, we tested part of the larger theoretical model by examining the indirect relationship between family functioning and adolescent anxiety and depression symptomatology via adolescent social competence for adolescents with ASD.
This study uses data from the Teens and Parents (TAP) Study (see Greenlee, 2019). Participants were adolescents aged 13-17 (N = 178; Mage= 14.92, SD = 1.31; 73% male) diagnosed with ASD, and their primary caregivers (PCs) who all identified as biological or adoptive mothers. PCs reported demographics and completed (1) the Self-Report of Family Inventory (SFI; Beavers & Hampston, 2000) to assess global family functioning via the Health and Competence subscale, and (2) the Social Responsiveness Scale (SRS; Constantino & Gruber, 2012) to assess deficits in adolescent social competencies. Adolescents reported their own depression and anxiety symptoms via the Revised Children’s Anxiety and Depression Scale-Short Version (RCADS; Ebesutani et al., 2012).
As shown in Figures 1 and 2, the indirect pathway from family functioning to social competence deficits and in turn to internalizing symptoms was statistically significant for adolescent anxiety (B= -1.015, SE = 0.394, 95% CI = [-1.893, -0.353]) and depression symptoms (B= -0.513, SE = 0.192, 95% CI = [-0.938, -0.189]) over and above the effects of family SES and adolescent age, sex, and restrictive and repetitive behavior. It was proposed that family functioning would play a role in adolescent mental health symptomatology via the mediating effect of social competence. Results support this hypothesis, indicating the importance of family functioning in youth social competence, and the subsequent effects on adolescent mental health. These results contribute to the understanding of mental health comorbidities in adolescents with ASD and could be used to inform future interventions.https://scholarscompass.vcu.edu/uresposters/1315/thumbnail.jp
Stardom, Spectacle, Show, and Salability: United Artists and the Founding of the Hollywood Blockbuster Model
United Artists was an independent film distribution company that Douglas Fairbanks, Charlie Chaplin, D.W. Griffith, and Mary Pickford jointly formed in 1919 to maintain creative autonomy over their work. Without the benefit of block booking practices through studio-owned theater houses, each founding artist established specific economic and aesthetic practices within their respective oeuvres in order to maintain company solvency. The resulting films produced during the company’s formative years (1919-1931) saw increased emphasis and innovation in regard to stardom, spectacle, show, and salability, features which ultimately innovated the model for the contemporary Hollywood blockbuster. Attributing the formation of the blockbuster to United Artists not only complicates the notion of the Hollywood blockbuster as a post-World War II phenomenon, but also broadens our comprehension of blockbuster filmmaking by formulating a model in which one can refine blockbuster criteria. This reframes the blockbuster as the cornerstone of the Hollywood film industry for over a century and presents it as a more persistent phenomenon
Application Of The Copyright Termination Provision To The Music Industry: Sound Recordings Should Constitute Works Made For Hire
An Explanation of Self Harm and Giving Help
Self harm is a highly misunderstood coping mechanism that often results in stigma. Self harm is the action of hurting one\u27s self with the intent of doing so. There are multiple factors and forms of self injury. Teenagers are the most likely to self harm due to the fact that they are not developed enough to handle emotions. Members of minorities are also more likely to self harm. People self harm for their individual reasons, but a common reason is to manage negative emotions.https://digitalcommons.usu.edu/fsrs2022/1023/thumbnail.jp
