Earth Abundant Transition Metal Catalysts for Activation and Functionalization of Light Hydrocarbons (open access)

Earth Abundant Transition Metal Catalysts for Activation and Functionalization of Light Hydrocarbons

Light hydrocarbons activations, functionalization, and reactions have been a subjects of catalysis research for decades but dominated by the rarer and more expensive noble metals. Switching over to using the more earth abundant third row transition metals could be more economical and less toxic but come with their own challenges. Their use as catalysts with light hydrocarbons could be employed better utilize and more efficiently use our hydrocarbon resources that the world still depends on.

Effect of pressure quenching on the structures and properties of borosilicate glasses: Insights from molecular dynamics simulations (open access)

Effect of pressure quenching on the structures and properties of borosilicate glasses: Insights from molecular dynamics simulations

Article describes how processes including hot compression, cold compression and subsequent annealing on the structures and properties are investigated and compared. They found that applying pressure up to 10 GPa at the glass transition temperature led to permanent densifications and a dramatic increase of elastic moduli by 90%, while thermal annealing reversed the increase and applying pressure at ambient temperature did not increase the modulus.

Effects of Enculturation in Neuropsychological Test Performance on the African Neuropsychological Battery in African Americans and First-Generation Sub-Saharan African Immigrants to the United States

This study used an archival data set of 26 healthy adult immigrants from a sub-Saharan African country to the United States (Mage 39.0, SD = 11.36; Meducation 16.33, SD = 2.88; 40.7% male). Additional archival data was used for 32 healthy African American adults (Mage 34.06, SD = 11.18; Meducation 16.16, SD = 2.49; 53.1% male). A bivariate correlation indicated that acculturation to African culture, as measured by the mBIQ (M 49.29, SD = 8.66), was significantly positively correlated with ethnicity, r = .632, p = .000, ηp2 = 0.399. Two-way ANOVAs revealed that African Americans were able to name more animals than African immigrants (F(1, 54) = 4.82, p = 0.32, ηp2 = 0.82) and exhibited greater organizational skills during a task of cognitive set shifting and problem solving than African immigrants, regardless of level of acculturation (F(1, 54) = 4.47, p =.039, ηp2 = 0.078). In contrast, African immigrants scored higher than African Americans on indigenous fruit (F(1, 54) = 7.60, p =.008, ηp2 = 0.123) and object naming (F(1, 54) = 5.59, p =.022, ηp2 = 0.094). Results of the study concluded that there are small variance effects in language tasks as well as strategy-based approaches to …

Efficient Convolutional Neural Networks for Image Processing Applications (open access)

Efficient Convolutional Neural Networks for Image Processing Applications

Modern machine learning techniques focus on extremely deep and multi-pathed networks, resulting in large memory and computational requirements. This thesis explores techniques for designing efficient convolutional networks including pixel shuffling, depthwise convolutions, and various activation fucntions. These techniques are then applied to two image processing domains: single-image super-resolution and image compression. The super-resolution model, TinyPSSR, is one-third the size of the next smallest model in literature while performing similar to or better than other larger models on representative test sets. The efficient deep image compression model is significantly smaller than any other model in literature and performs similarly in both computational cost and reconstruction quality to the JPEG standard.

The Emergence of All-State Vocal Jazz Ensembles in the United States from 1978 to 2022 (open access)

The Emergence of All-State Vocal Jazz Ensembles in the United States from 1978 to 2022

Since the creation of the first all-state vocal jazz ensemble in 1978, similar ensembles have been established in roughly half of the United States. This paper contains historical summaries of the creation of all-state vocal jazz ensembles in nineteen of those states, primarily as recounted via interviews with those ensembles' founders. Each semi-structured interview was conducted over video conference or phone and lasted approximately one hour; resulting interview data was analyzed using qualitative methods. During the creation of each ensemble the respective founders needed to secure the support of a host organization, determine where and when to convene, and decide how to address auditions, sound reinforcement, rhythm sections, and funding. The diversity of solutions to these shared challenges reflects the diverse priorities of each founder as well as the unique conditions in which each all-state vocal jazz ensemble was established. However, several elements were common across these stories, including the influence of existing festivals and all-state ensembles, and tensions within the choral education community regarding the value of the vocal jazz idiom relative to traditional choirs, show choirs, and other vocal ensembles. In a few cases, established all-state vocal jazz ensembles were discontinued; these stories further illustrate the challenges such …

Encroachment order and spatial patterns of broad-leaf tree species in the naturalization of a Cunninghamia lanceolata plantation (open access)

Encroachment order and spatial patterns of broad-leaf tree species in the naturalization of a Cunninghamia lanceolata plantation

Authors of the article state that the aim of this study was to understand the encroachment order, spatial patterns, interspecific associations, and species diversity of a Cunninghamia lanceolata plantation and to provide context for how to improve the spatial structure of C. lanceolata plantations. Their results show that the encroachment of broad-leaf trees into the C. lanceolata plantation followed a clear successional sequence of tree community assembly: intolerant tree species encroachment first, such as Alniphyllum fortunei and Liquidambar formosana, encroached; neutral tree species then encroachment, such as Daphniphyllum oldhamii and Schima superba, and shade-tolerant tree species encroachment last, such as Castanopsis eyrei and Castanopsis tibetana.

Engineering Cardiac Organoid Vascularization via Fluid Shear Stress and Vascular-Promoting Growth Factors

Cardiovascular disease (CVD) is the leading cause of death internationally. Efforts to decrease CVD death has been explored through stem cell technology, specifically organoid formation. Current cardiac organoid models lack the vascular networks for nutrient supply and maturation. In this study, pillar perfusion technology is used to fabricate cardiac organoids and induce vascularization via dynamic culturing and the addition of vascular promoting growth factors (GFs). In addition to this study, a millifluidic chip is engineered for shear stress application via flow simulations and experimental flow analysis. We successfully optimized the millifluidic chip to achieve fluid shear stress of 20mPa and validated through particle tracking velocimetry using 0.1um diameter beads under flow. The results of cardiac organoids displayed contraction and growth of endothelial cells (ECs) under dynamic flow with GFs. In addition, smooth muscle cells (SMCs) displayed growth via GFs in both dynamic and static culturing. Although vascular networks were not present in all conditions of this experiment, this thesis can serve a basis for searching other methods of inducing vascularization.

English Loanwords in French: A Corpus-Driven Analysis of Corporate Websites (open access)

English Loanwords in French: A Corpus-Driven Analysis of Corporate Websites

This thesis explores the use of English loanwords in French discourse found on seven France-based corporate websites and the website of one government ministry in France. The following overarching question guided this research project: To what extent are English loanwords used in French for marketing purposes or other reasons? As expected, the results varied greatly from website to website, but it is clear from my analysis of this relatively small corpus that the use of English is widespread in French discourse. In this thesis, I allowed myself to engage in some speculation based on my own background and experiences. I acknowledge that further research is needed in order to provide a more comprehensive analysis of English loanwords in French since this is a very complicated topic that can be approached from many different angles.

Epistemological, Ontological, and Ethical Dimensions of Biocultural Rights: The Case of the Atrato River, Colombia (open access)

Epistemological, Ontological, and Ethical Dimensions of Biocultural Rights: The Case of the Atrato River, Colombia

In 2016, the Colombian Constitutional Court recognized the Atrato River as a subject of rights based on the theory of biocultural rights. This dissertation analyzes a new legal concept that aims to defend the rights to a good life for humans and other-than-human co-inhabitants who share river ecosystems, focusing on the case of the Atrato River in Colombia. The 3Hs framework of biocultural ethics is adopted to interconnect complex and interrelated historical, biophysical, cultural, and political dimensions. With this analysis, broader biocultural approaches are suggested. They could be valuable for understanding and implementing biocultural rights in other world regions. Moreover, it could transform the current situation that destroys biocultural diversity toward public policies that favor more just and sustainable forms of co-inhabiting biocultural diversity. A primary limitation of the implementation of biocultural rights is the context of a "failed state," in which the Colombian State is subject to severe problems of corruption, illegal mining, conflicts between legal and illegal armed groups, and drug trafficking. There is a need for a dialogue solution to the conflict. This requires that illegal armed groups are valued as co-inhabitants. Achieving social-environmental justice is essential for biocultural ethics. In this case, it is the condition …

Ethnic Parties: Their Emergence, Survival, and Impact

This dissertation examines the emergence of ethnic parties, their survival in the political system, and their impact on the governance practices. While scholars have long debated the impact of ethnic parties on state-building and democratization process, few works have empirically examined their behavior in the political system. Empirical research on ethnic parties is limited to single countries or regions -- Latin America, Eastern Europe, or a few countries including India. Firstly, this dissertation extends the research on ethnic parties to include another South Asian Country – Nepal. Secondly, research on ethnic parties has been hampered by the lack of cross-sectional data on ethnic parties. This dissertation employs new datasets on the electoral performance of ethnic parties, making use of the newly available resource. Employing both qualitative and quantitative techniques, this dissertation is built around three empirical chapters. Firstly, it argues that strategic interactions between major parties and ethnic groups, among others, determine why some ethnic groups successfully form their own parties and others do not. Secondly, it argues that the factors that are responsible for the emergence of ethnic parties are hardly sufficient for the survival of these parties in the long run and shows that ethnic parties' access to …

An Evaluation of Differential Attention on Preferred Topics of Conversation for Adults with Autism Spectrum Disorder

Extensive speech on preferred conversation topics may limit conversations with others. For individuals with ASD, extensive speech on a topic may be a form of restricted or repetitive behavior that may be addressed through skill building. However, previous research suggests that skill building may not be necessary if the behavior is sensitive to differential reinforcement contingencies. To evaluate the effects of differential reinforcement in the form of attention on conversation topics, we replicated the results of Stocco et al. by assessing sensitivity to conversational attention with participant-only topic initiations. Additionally, we extended the procedures by evaluating the effects of topic initiations from the participant and the experimenter (shared initiations). Similar to previous research, our results yielded that speech was sensitive to conversational attention across all participants. That is, differential reinforcement contingencies altered levels of speech on topics of conversation, indicating that differential reinforcement procedures may be sufficient in addressing performance deficits. Lastly, we assessed participant preference for participant-only initiation or shared initiation conversations.

An Evaluation of Pharmaceutical Industry Representatives' Learning Experiences: Pandemic-Related Compliance Training Understood for the Future (open access)

An Evaluation of Pharmaceutical Industry Representatives' Learning Experiences: Pandemic-Related Compliance Training Understood for the Future

This study employed Kirkpatrick's training evaluation model to better examine the reactions and learning experiences of a group of pharmaceutical industry sales professionals who participated in pandemic-related virtual compliance training in spring 2020. The field of learning technologies has few examples and limited knowledge regarding the evaluation of virtual training in the context of pandemic-related compliance training in the biopharmaceutical sector. This qualitative study employed semi-structured interviews to collect data from industry participants, allowing an examination of their experiences relative to the first three stages of Kirkpatrick's training evaluation framework, namely the reactions of the trainees, the knowledge transferred to the trainees, and the performance as it relates to the trainees' changed behaviors because of their participation in virtually delivered training.

Examining the Role of Emotion Dysregulation and Rumination in the Relationship between PTSD Symptom Severity and Sleep Disturbances

Emotion dysregulation and rumination are involved in the development, maintenance, and treatment of both posttraumatic stress disorder (PTSD) and sleep disturbances. We examined if and how these factors influenced the nature of the relationship between PTSD symptom severity and subjective sleep disturbances among trauma-exposed individuals. Using data gathered from a community sample of 199 trauma-exposed individuals (Mean age = 35.48; 59.80% female), we examined whether there were stronger significant associations between greater PTSD symptom severity and poorer sleep quality/lower sleep quantity at higher (vs. lower) levels of (1) negative emotion dysregulation and positive emotion dysregulation (both included in the same model) and (2) rumination. Participants recruited via Amazon's Mechanical Turk completed the PTSD Checklist for DSM-5, Brief Version of the Difficulties in Emotion Regulation Scale, Difficulties in Emotion Regulation Scale – Positive, Ruminative Thought Style Questionnaire, and sleep quality/quantity items from the Pittsburgh Sleep Quality Index. Results of simple and additive multiple moderation analyses showed that neither negative/positive emotion dysregulation nor rumination moderated the relationships between PTSD symptom severity and sleep quality/quantity. Exploratory analyses showed that negative emotion dysregulation (when examined independently) moderated the relationship between PTSD symptom severity and sleep quality. There were also significant associations between poorer sleep …

Executive Functioning Processes in Simple and Complex Theory of Mind Tasks (open access)

Executive Functioning Processes in Simple and Complex Theory of Mind Tasks

Using a multimethod-multimodal approach, this study compared the contributions of executive function (EF) abilities (Go No-Go, Visual Search, 2-Back task, and Task Switching) to narrative comprehension tasks (False Belief, Strange Stories, Self-Reported Theory of Mind Inventory [TOMI-SR]) and a narrative production task (interpersonal decentering) in a sample of young adults. Separate regression models were conducted for each theory of mind (ToM) measure with EF measures as predictor variables and empirically selected demographic variables controlled. As expected, in this college student sample (N = 110), False Belief demonstrated a ceiling effect and was not associated with any EF ability. Task Switching and 2-Back accounted for significant variance in Strange Stories. No EF task significantly predicted performance on TOMI-SR or interpersonal decentering. Both story comprehension tasks (False Belief and Strange Stories) were significantly associated, but these tasks were not correlated with either self-reported ToM or interpersonal decentering. Several unanticipated demographic associations were found; having more siblings and English proficiency accounted for significant variability in Strange Stories; education, presence or absence of self-disclosed autism diagnosis and mental health diagnosis explained a large portion of variance in TOMI-SR; interpersonal decentering maturity differed significantly between cisgender men and cisgender women. Lastly, interpersonal decentering number of …
