Injury Surveillance In Community Cricket: A New Inning For South Africa, Benita Olivier, Oluchukwu L. Obiora, Candice Macmillan, Caroline Finch

Research outputs 2022 to 2026

Published injury rates amongst elite and club-level youth cricketers highlight the need to implement injury risk-reducing strategies amongst the youth cricketing population. Data from sports injury surveillance systems are a prerequisite for the development and evaluation of strategies to reduce injury risk. Therefore, collecting injury surveillance data is a positive move towards reducing injuries in cricket. In South Africa, a systematic, standardised, evidence-informed injury surveillance system currently does not exist for community levels of play, namely, in cricket-playing high schools and cricket clubs. Although injury surveillance systems exist at elite levels, the obvious differences in elite versus community cricket settings …

Addressing Filicide In Ghana: Linking Cultural Understanding With The Law Against Filicide. Does The Law Work?, Alhassan Abdullah, Margarita Frederico, Felix Mensah, Hajara Bentum, Yihang Wang, Jennifer Litela Asare

Research outputs 2022 to 2026

Introduction: Consistent with international promulgation on the criminalization of filicide, Ghana’s Children’s Act 1998 (560) and the Criminal Justice Act criminalizes any form of torture against children. Yet, perpetrators of filicide in Ghana may go unpunished due to the beliefs in cultural norms that justify filicide acts. The cultural narratives of filicide can impede on the application and effectiveness of the laws of filicide. Method: The study employed a vignette approach to explore the views of 19 adults, who were parents between 69 years of age and 30 years of age, in rural and urban Ghana on the laws of …

Bioturbation By Echidna (Tachyglossus Aculeatus) In A Forest Habitat, South-Western Australia, Shannon J. Dundas, Lara Osborne, Anna J. M. Hopkins, Katinka X. Ruthrof, Patricia A. Fleming

Research outputs 2022 to 2026

Bioturbation by digging animals is important for key forest ecosystem processes such as soil turnover, decomposition, nutrient cycling, water infiltration, seedling recruitment, and fungal dispersal. Despite their widespread geographic range, little is known about the role of the short-beaked echidna (Tachyglossus aculeatus) in forest ecosystems. We measured the density and size of echidna diggings in the Northern Jarrah Forest, south-western Australia, to quantify the contribution echidna make to soil turnover. We recorded an overall density of 298 echidna diggings per hectare, 21 % of which were estimated to be less than 1 month old. The average size of digs was …

Comparison Of Auditory Steady-State Responses With Conventional Audiometry In Older Adults, Hadeel Y. Tarawneh, Hamid R. Sohrabi, Wilhelmina H. A. M. Mulders, Ralph N. Martins, Dona M. P. Jayakody

Research outputs 2022 to 2026

Behavioral measures, such as pure-tone audiometry (PTA), are commonly used to determine hearing thresholds, however, PTA does not always provide reliable hearing information in difficult to test individuals. Therefore, objective measures of hearing sensitivity that require little-to-no active participation from an individual are needed to facilitate the detection and treatment of hearing loss in difficult to test people. Investigation of the reliability of the auditory steady-state response (ASSR) for measuring hearing thresholds in older adults is limited. This study aimed to investigate if ASSR can be a reliable, objective measure of frequency specific hearing thresholds in older adults. Hearing thresholds …

Stem Cell Therapy For Insulin-Dependent Diabetes: Are We Still On The Road?, Lu Yang, Zhu-Meng Hu, Fang-Xu Jiang, Wei Wang

Research outputs 2022 to 2026

In insulin-dependent diabetes, the islet β cells do not produce enough insulin and the patients must receive exogenous insulin to control blood sugar. However, there are still many deficiencies in exogenous insulin supplementation. Therefore, the replacement of destroyed functional β cells with insulin-secreting cells derived from functional stem cells is a good idea as a new therapeutic idea. This review introduces the development schedule of mouse and human embryonic islets. The differences between mouse and human pancreas embryo development were also listed. Accordingly to the different sources of stem cells, the important research achievements on the differentiation of insulin-secreting β …

Do Personal Values Have An Effect On Self-Esteem In Middle Childhood?, Patricia R. Collins, Joanne Sneddon, Julie Ann Lee

Research outputs 2022 to 2026

Research on children's values (i.e., broad motivational goals) largely focuses on whether their values have a similar theoretical pattern of organization to those of adults, whether they hold similar value priorities to adults or adolescents, and how their values relate to social behavior. However, little is known about how values relate to wellbeing in middle childhood. We examined relations between the values of children aged 6–12 and aspects of their self-esteem, including global self-worth and five domain-specific-competencies. We found global self-worth and physical appearance were positively related to self-transcendence, conservation, and openness-to-change values, and negatively related to self-enhancement values. Social …

Unstacking The Matryoshka Nesting Doll: A Self-Study Of Playful Language Instruction For Adult Second Language Learners, Marine Pepanyan

Dissertations and Theses @ UNI

In the recent three decades teaching second language (L2) vocabulary has expanded from sentence-level morphosyntactic features and pragmatics to the promotion and advancement of Communicative Language Teaching (CLT). Nevertheless, the L2 instructors are constantly seeking alternative strategies for vocabulary teaching and assessment due to a superficial level of vocabulary memorization and lack of student engagement. As an instructor-practitioner, I undertook a self-study of the process of implementing Playful Language Instruction (PLI) of L2 vocabulary in an Intensive English Program. In this self-study I combined conceptual lenses of theories of play, CLT, and the Adult Learning Theory to examine how playful …

Quantifying Genomic Diversity And Growth In Iowa Bluegill, Jeremy Raymond Abels

Dissertations and Theses @ UNI

Bluegill (Lepomis macrochirus) is one of the most fished species in Iowa. However, after an initial stocking event, lakes rarely receive additional stockings owing to a high rate of natural reproduction. For this reason, the genetic diversity of Bluegill populations remains understudied in the context of fisheries and natural resource management. Additionally, the extent to which genetics influences the growth rate of Bluegill on a population level has not yet been extensively examined. The goal of this study was to understand the diversity of Iowa’s Bluegill population and to determine if there is a genetic association with growth …

Association Between Habitat And The Genetic Diversity Of The Brown-Belted Bumblebee (Bombus Griseocollis) In The Agricultural Landscape Across Northeast Iowa, Clarissa Elizabeth Bruns

Dissertations and Theses @ UNI

Wild bumblebees (Hymenoptera: Apidae) are key pollinators in natural ecosystems and major contributors to pollination in agriculture. Despite this, numerous bee species are in decline from introduced pathogens, pesticides, and habitat fragmentation. In the Midwestern United States, the land is dominated by agricultural landscape, and farming practices result in limited floral resources and frequently disturbed nesting grounds for bee species. In this thesis, I examine the genetic diversity between and within populations of brown-belted bumblebee (Bombus griseocollis) across northeast Iowa and test for population genetic structure between reconstructed prairies within 3 years of establishment and prairies >10 years …

Not Our Problem: Ingroup Glorification Facilitates Moral Disengagement And Exclusion, Matthew Gunderson

Dissertations and Theses @ UNI

The present study examined how ingroup/outgroup identification and harm predict cognitive restructuring and the shifting of blame. Drawing on Moral Disengagement Theory (Bandura, 1999), which holds that individuals create a new version of reality that allows them to violate their moral beliefs, I hypothesized that implicating the ingroup, lower levels of perceived harm, and higher ingroup glorification would result in more moral disengagement. Integrating Moral Disengagement Theory with Moral Exclusion Theory (Opotow, 1990), I further hypothesized that moral exclusion—the removal of others from the moral community—would also be greater. 422 participants recruited over Prolific read a modified news article about …

Students Vs. Suspects: A Qualitative Examination Of Stereotype Threat And The Impact On Behavior Of Black Males, Ryan J. Williamson

Dissertations and Theses @ UNI

This qualitative study focused on the impact of stereotype threat on the behavior of black males in the educational system. Black males currently involved in the juvenile justice system were interviewed about their lived experiences in the educational system. The literature surrounding stereotype threat focuses on academic achievement and performance. It provides spaces in the potential of stereotype threat impacting behavior.

Stereotype threat argues that individuals will confirm a self-characteristic which supports a negative stereotype associated with a specific group within society (Spencer et al., 2016). In theory, people will underperform based on a preconceived notion of failure. If a …

The New Independents: A Historical Analysis Of Webcomics And Webtoon, Leonal A. Sepúlveda S.

Dissertations and Theses @ UNI

Webcomics have now existed as a form of graphic literature for slightly over thirty years, evolving along with computer technology and in turn reflecting the changes in culture, style and preferences for both independent artists on the Internet and their audiences. The evolution of the webcomic illustrates how the changing trends in technology and profit interests shape stylistic and narrative sensibilities. In turn, the offshoot medium of webtoons, whose history parallels the webcomic directly, illustrates the way the presentday independent webcomic sphere is shaped by the demands of contents platforms that demand its creatives constantly produce content to maintain active …

Media Framing Of Marriage Practices In Afghanistan, Hakima Afzaly

Dissertations and Theses @ UNI

Culturally, in Afghanistan, marriage is given much importance and seen as something that completes life. Through this study, I analyze how marriage practices, such as dowry (Mahr), bride price, and the “virginity ritual,” are described in newspapers and magazines of Afghanistan. In particular, I explore how the popular press, such as 8 Sobh and Khama Press in Afghanistan frame their discussion of marriage practices. The findings from this analysis reveal that newspapers and magazines of Afghanistan frame marriage as an economic issue and a major focus of the articles is on the financial pressure on poor families due to the …

"Land Of The Silver Birch": Environmental Attitudes And Place-Making In A Northern Minnesota Boy Scout Camp, 1960-1975, John Mark Fretham

Dissertations and Theses @ UNI

In 1959, leaders of the Minnesota Valley Council, BSA (headquartered in Mankato, MN) began making plans to create a new Boy Scout camp to replace their recently built camp in Southern Minnesota. The previous fifteen years of the post-World War II era had produced significant shifts in ideas about wilderness, what constituted quality outdoor recreation, growing anxiety about masculinity in the Cold War era, and expansion of the promotion and adoption of a North Woods tourist culture. These changes helped lead the council to begin looking for a site to create a new Boy Scout camp and build Camp Cuyuna …

Improving Age Of Information With Interference Problem In Long-Range Wide Area Networks, Preti Kumari, Hari Prabhat Gupta, Tanima Dutta, Sajal K. Das

Computer Science Faculty Research & Creative Works

Low Power Wide Area Networks (LPWAN) offer a promising wireless communications technology for Internet of Things (IoT) applications. Among various existing LPWAN technologies, Long-Range WAN (LoRaWAN) consumes minimal power and provides virtual channels for communication through spreading factors. However, LoRaWAN suffers from the interference problem among nodes connected to a gateway that uses the same spreading factor. Such interference increases data communication time, thus reducing data freshness and suitability of LoRaWAN for delay-sensitive applications. To minimize the interference problem, an optimal allocation of the spreading factor is requisite for determining the time duration of data transmission. This paper proposes a …

Editorial: Fire Regimes In Desert Ecosystems: Drivers, Impacts And Changes, Eddie J. B. Van Etten, Matthew L. Brooks, Aaron C. Greenville, Glenda M. Wardle

Research outputs 2022 to 2026

Although not commonly associated with fire, many desert ecosystems across the globe do occasionally burn, and there is evidence that fire incidences are increasing, leading to altered fire regimes in this biome. The increased prevalence of megafires (wildfires > 10,000 ha in size and typically damaging) in most global biomes is linked to climate change, although those occurring in deserts have received far less attention, from both a research and policy perspective, than that of forested ecosystems (Linley et al., 2022). Understanding the drivers of desert fires, from climate to landscape patterns of hydrology and soil, and how these may be …

Critical Review Of The Use Of The Rorschach In European Courts, Igor Areh, Fanny Verkampt, Alfred Allan

Research outputs 2014 to 2021

In relation to the admissibility of evidence obtained using projective personality tests arose in F v. Bevándorlási és Állampolgársági Hivatam (2018). The Court of Justice of the European Union has held that an expert’s report can only be accepted if it is based on the international scientific community’s standards, but has refrained from stipulating what these standards are. It appears timely for European psychologists to decide what standards should be applied to determine whether or not a test is appropriate for psycholegal use. We propose standards and then apply them to the Rorschach because it was used in this case …

Voicing Derbarl Yerrigan As A Feminist Anti-Colonial Methodology, Vanessa Wintoneak, Mindy Blaise

Research outputs 2014 to 2021

The paper voices Derbarl Yerrigan, a significant river in Western Australia, through three imperfect, non-innocent, and necessary river-child stories. These stories highlight the emergence of a feminist anti-colonial methodology that is attentive to settler response-abilities to Derbarl Yerrigan through situated, relational, active, and generative research methods. Voicing Derbarl Yerrigan influences the methodological practices used as part of an ongoing river-child walking inquiry that is concerned with generating climate change pedagogies in response to the global climate crises and calls for new ways of thinking and producing knowledge. In particular, the authors found that voicing as a methodology includes listening and …
