Reactivity and Electronic Structure Studies of Ce(IV) and Th(IV) Imido Compounds
No full textOrganometallic compounds with a multiply bound imido ligand have been extensively studied as intermediates in catalytic transformations. While the examples of d-block transition metal imido compounds are ubiquitous, early lanthanide and actinide compounds are more rare. There is a long-standing interest to improve understanding of their chemical behaviors and electronic structures. This dissertation presents work on several aspects of f-element imido chemistry, including reactivity, electronic structures, and photophysical properties. Cerium (IV) imido compounds supported by a tripodal hydroxylaminato ligand framework were used to activate small molecules with polar bonds, such as carbon dioxide, organic isocyanates, ketones, and others. Reaction products were isolated, affording insights into reaction mechanisms and comparisons with d-block transition metal and actinide imido complexes. Electronic structures of cerium (IV) oxo and imido compounds were investigated using XAS spectroscopy, magnetic measurements, and DFT calculations, revealing single-reference ground states and significant temperature-independent paramagnetism. This study improved understanding of ligand impact on the electronic character of the ground state of cerium (IV) organometallic compounds. It was also found that the cerium (IV) imido compounds exhibited no solution-state luminescence, while isostructural thorium (IV) imido compounds were luminescent. By systematically varying the para-substituents on the aryl-imido ligand based on their electron donating and withdrawing ability, a series of thorium imido compounds was prepared, and their photophysical properties were measured. All the thorium(IV) compounds emitted in the blue and the ultraviolet region. Rationalizing the results with DFT calculations, we proposed the role of different radiative transitions and their relative energies in the observed luminescent behavior
The Applicability of Undergraduate Entrepreneurship Curriculum and Ecosystem to Support Startup Founders: A Study of Selected Universities in Indonesia
No full textEntrepreneurship education has become a trending topic among higher education institutions in Indonesia as the government pushes for more entrepreneurs through its Kampus Merdeka (campus freedom) policy. This trend gets amplified with the recent burst of technology startups growing and scaling in Indonesia to heights that have never been seen by the country before. A couple of the home-grown startups eventually become publicly listed companies, increasing the overall startup fever across the nation. Lies beneath the success of this educational policy to support entrepreneurship in Indonesia is how to have a relevant curriculum and ecosystem to support student entrepreneurs. Prior research papers have proposed several aspects to be measured, namely, entrepreneurial skills, attitude, environment, and intentions. However, those studies still lack the holistic analysis regarding entrepreneurship education in the country and mostly only involved students. This dissertation studies the applicability of undergraduate entrepreneurship education and ecosystem to support startup founders by interviewing educators, students, alumni, and school leaders at selected public and private universities in Indonesia. I employ a qualitative study with open-ended interview questions for data collection and analysis. My research contributes to the gaps in the literature as this paper is the first of its kind research publication with a holistic approach, involving relevant stakeholders and more variables in the analysis. The findings of this research suggest educational policy makers and university leaders can support the applicability of the entrepreneurship curriculum and ecosystem by focusing on ecosystem building, collaboration with the broader communities, student engagement, government support, faculty development, and alumni community

Utilizing Cinematic Stories to Shift Fear Into Compassion Towards Pit Bull Type Breeds
Get PDFCreating entertaining yet educational stories to cultivate curiosity in caring for animals can improve animal welfare as well as our own public health under a One Health initiative. More specifically, tailoring well-crafted cinematic stories utilizing thoughtful anthropomorphism about misunderstood dog breeds such as pit bulls can potentially debunk sensationalized media myths surrounding their reputation. Further research is worth pursuing on how an anthropomorphic film with an emotional arc utilizing a non-aggressive pit bull character can decrease a population\u27s previous concerns of “scary” dog breeds discriminated against under breed specific legislation while also championing the use of particular films as moral educators. While the pilot data showed both positive and negative trends in subjects’ perceptions of pit bulls, “scary” dog breeds, and animal sentience after watching the film Kitbull, emotional cinematic stories and the content within those stories matter. We as animal welfare scientists and media professionals must work in collaboration to create truthful yet compelling stories utilizing anthropomorphism more thoughtfully so that we may nurture an audience’s empathy and compassion towards misunderstood animals in society. By increasing our efforts in improving domesticated dog welfare with a focus on debunking societal myths about mislabeled “dangerous” dog breeds such as the pit bull through motion picture stories, we not only better animal and human welfare within local communities, but world-wide
The New Hollywood: A Producer’s Approach to Positive Production Through Enhanced Relationships
Get PDFSince its inception, Hollywood has enjoyed the benefits of privilege and prestige based in part because of scarcity of resources (i.e., financing, information, labor, equipment). Today’s technology has leveled the filmmaking landscape, and the incoming generation of filmmakers are less tolerant of the traditional devaluing behaviors in Hollywood. If the resources are no longer coveted and the typical behaviors not accepted, can Hollywood remain the filmmaking leader? This paper suggests that it can by evolving its behaviors to nurture people and relationships instead of exploit and deplete them. By utilizing tools such as positive psychology’s well-being model PERMA and positive organizational scholarship’s high-quality connections, the industry can inspire artists by shifting away from traditional devaluing behaviors and create a culture of support. Hollywood can leverage its position as the world’s foremost creative collective to influence new standards of relationships in production that prioritize genuine kindness, trust, and respectful engagement, or as this filmmaker calls it positive production
Raising Flourishing Adults: How Positive Psychology Can Help Adolescents Rise Above Stressful Life Events to Lead Flourishing Adult Lives
Get PDFAdolescence is a time of dramatic change and growth across multiple systems. Simultaneous development of neural, biological, and social domains of functioning renders adolescence a heightened period of sensitivity to early life experiences. Among these experiences, stressful life events are shown to disrupt the architecture of the developing brain, increasing the risk of future mental health disorders, such as depression and anxiety. In this paper, I discuss the risk of adolescence, such as the vulnerabilities to stress, alongside the unique plasticity that creates an opportunity for positive external influences (e.g., family milieu). Finally, I propose a multidimensional construct, known as RISE, for adolescent flourishing borrowing from other validated positive psychology concepts. A workshop and specific interventions to improve each of the four elements of RISE are proposed that can be used by parents
Adjusting to the New Normal(ization): Adapting Atlas of North American English Benchmarks to Lobanov-Normalized Data
Get PDFThe Atlas of North American English (Labov et al. 2006) defines criteria for participation in certain dialect features in terms of formant benchmarks; e.g., a speaker is considered to have a raised TRAP vowel if their mean normalized F1 of TRAP is less than 700 Hz. Other researchers often compare their own findings to these benchmarks; but the majority of recent research in North American sociophonetics uses the Lobanov (1971) method to normalize formant measurements, producing values that are formally incomparable with Atlas benchmarks. This paper proposes a method of transforming benchmarks into Lobanov-comparable values. Benchmarks are expressed as z-scores relative to the entire Atlas corpus of normalized formant measurements, whose mean F1 is 650.7 Hz (s.d. 150.0 Hz) and mean F2 is 1595.5 Hz (s.d. 435.2 Hz). Thus, for example, a benchmark of 700 Hz in F1 is converted to 0.329 in Lobanov terms. This method is evaluated by comparing the effectiveness of the Lobanov-transformed benchmarks at distinguishing dialect regions to that of the original Atlas benchmarks. Fourteen such benchmarks are evaluated against three isogloss parameters; in 76% of cases, the Lobanov-transformed benchmarks are at least as effective as the original Atlas benchmarks at characterizing the Atlas\u27 dialect regions. Therefore, this transformation can be recommended for researchers who want to compare Lobanov-normalized data to Atlas benchmarks
Effect of Accent Perception on the Perception of Professionalism
Get PDFThis study explores how people’s perceptions of speakers’ accents may be related to their perceptions of speakers’ professional characteristics. Sociolinguistic research continues to highlight that the ways listeners perceive accents and the ways they perceive the people who use those accents are intertwined. In addition, accent discrimination is often an underlooked form of discrimination in various aspects of society, including in workplace situations – from interview success to upward mobility. The U.S. judicial system, in theory, condemns discrimination based on national origin, race, socioeconomic status, etc. but, in reality, provides leeway for employers to discriminate based on language and uphold beliefs in standard language ideology. In the U.S., English speakers tend to view non-native English speakers as less credible or believable than native English speakers, but few other studies have explored this relationship between accent perception and the perception of personal characteristics. Our study contributes to sociolinguistic research on accent perception by exploring how accentedness interacts with the perception of specific character traits prioritized in professional situations: professionalism, confidence, believability, knowledgeability, and level of experience
