Taxi Geometry And Euclidean Geometry: Congruence And Similarity Of Triangles, Jose Carlos Pinto Leivas, Osvaldo Jesus Rojas Velazquez, Diana Carolina Perez Duarte, Randy Zabaleta Mesino

Neutrosophic Sets and Systems

This article presents an instrument that describes the experience implemented with students of a graduate programme in the courses of Analytic Geometry and Linear Algebra. The purpose of the instrument, as a didactic resource, was to analyse how the connections between the classical cases of congruence and similarity of triangles in Euclidean Geometry and in Taxi Geometry can be explored. The metric analysis of the productions shows that the three classical congruence criteria - SSS, SAS and ASA - cease to hold under the taxicab metric, and that equilaterality does not imply equiangularity in that geometry. In addition, a neutrosophic …

How Certain Is An Institutional Research Profile? Three Undeclared Decisions, And A Neutrosophic Reading Of What They Cost, Alexis Matheu Perez, Bastian Gutierrez

Neutrosophic Sets and Systems

Institutional bibliometric profiles report Lotka's exponent, a Bradford core and a Price ratio as if they were properties of the institution. They are properties of the institution together with three decisions that the reporting almost never states: which source defines the corpus, which document types are compared, and which population of authors the laws are fitted on. This article measures what each decision is worth, using Universidad Bernardo O'Higgins (UBO, Santiago, Chile) as the case and Universidad Bolivariana del Ecuador as a control. Since the resulting uncertainty is not sampling error, we give it a place to be reported: a …

How Do Ai Service Agents Impact Tourists’ Pro-Environmental Behavior? The Effects Of Childlike Anthropomorphism And Moral Disengagement, Lujun Su, Liqin Gong, Yinghua Huang, Xuehuan He

Faculty Research, Scholarly, and Creative Activity

Drawing on moral disengagement theory, this research examines how service provider type shapes tourists' pro-environmental behavior. Across five studies including four scenario-based experiments and a field experiment, we show that AI service agents, compared with human service providers, tend to reduce tourists' pro-environmental intentions and behaviors. Moral disengagement serves as the psychological mechanism underlying this effect, such that AI service agents increase tourists' moral disengagement, which in turn weakens their pro-environmental behavior. We further show that childlike anthropomorphism attenuates this process by reducing moral disengagement: with childlike anthropomorphic AI tourists’ pro-environmental responses are comparable to their responses to human service …

The Relationship Between Adverse Childhood Experiences, Protective And Compensatory Experiences, And Parenting Attitudes Among Fathers, Kylie Schmidt

Dissertations

Adverse childhood experiences (ACEs) are defined as potentially traumatic events that occur in childhood particularly between the ages of 0 and 17 years that negatively influence long-term health, relational functioning, and parenting practices (Centers for Disease Control and Prevention, 2026; Felitti et al., 1998; Merrick et al., 2019). Conversely, protective and compensatory experiences (PACEs) have emerged as protective factors that foster resilience and possibly buffer against the adverse outcomes of ACEs (Narayan et al., 2018). As the existing research has greatly focused on mothers, little is known about how men’s early life experiences shape their parenting attitudes, particularly during the …

Examining The Impact Of Social Support On Academic Self-Efficacy In Black Doctoral Students In Psychology, Asia A. Hall

Dissertations

This study examined the relationship between perceived social support and academic self-efficacy, or academic confidence, among Black doctoral students in psychology programs at predominantly White institutions (PWIs). Grounded in self-efficacy theory, the study was designed to explore whether perceived social support was associated with and predictive of students’ academic confidence. A quantitative, cross-sectional design was used, and data were collected using adapted versions of the Multidimensional Scale of Perceived Social Support (MSPSS) and the Academic Self-Efficacy (ASE) scale. The sample consisted of 60 Black doctoral students enrolled in psychology programs at PWIs across the United States. Descriptive statistics indicated the …

Offline And Thriving: Understanding The Professional And Personal Lives Of Non-Social Media Users In A Digitally Dominant Era, Bhargava Mantena

Dissertations

Existing research has treated voluntary social media abstinence as the absence of users rather than as a condition worth study. This mixed-methods study examined its psychological and occupational correlates. Adults aged 21 to 65 reporting abstinence from all major platforms for six months or more completed three validated instruments measuring mental well-being, work engagement, and perceived social isolation; a purposive subsample of 12 took part in semi-structured interviews. The analysis set comprised 120 participants, below the 128 indicated by the a priori power analysis. Research Question 1 could not be tested as approved, because no active-user comparison group was recruited; …

Cognitive-Affective And Somatic Depressive Symptom Domains Related To Psychological Mechanisms And Sociodemographic Factors, Danielle B. Hazeltine

Dissertations, Theses, and Capstone Projects

Major depressive disorder is prevalent, chronic, and heterogeneous, including cognitive- affective (e.g., maladaptive beliefs or thinking patterns and sad mood) and somatic (e.g., fatigue, appetite, or sleep changes) symptom domains. While depression domains have been long theorized, research examining psychological mechanisms underlying this distinction is limited. Preliminary research suggests cognitive-affective symptoms relate more strongly to cognitive mechanisms (cognitive bias, perseverative thought), somatic symptoms relate more strongly to behavioral mechanisms (behavioral inhibition/activation), and gender, race, and ethnicity moderate these relationships. This study examined whether cognitive-affective and somatic symptom domains differentially relate to cognitive and behavioral mechanisms, and whether these relationships are …

Distinguishing Between Complex Post-Traumatic Stress Disorder And Post-Traumatic Stress Disorder: The Role Of Childhood Maltreatment, Catherine Harris

Dissertations, Theses, and Capstone Projects

The current study examined whether court-substantiated childhood maltreatment may be associated with increased risk for Complex PTSD (CPTSD) and whether individuals with CPTSD and individuals with PTSD could be distinguished in terms of complex trauma exposure. Children with documented cases of abuse and neglect prior to age 11 were matched on age, race, sex, and approximate family socioeconomic status with children without documented histories of maltreatment (controls) and both groups were followed prospectively into adulthood. Participants (N = 1,196) were assessed using a DSM-III-R based structured interview of PTSD symptoms and other self-report measures of psychiatric symptoms at mean age …

Social Media-Based Social Comparisons Among Socially Anxious Young Adults: The Role Of Cognitive Reappraisal, Jennifer L. De Rutte

Dissertations, Theses, and Capstone Projects

Social media is a central context for social interaction and self-evaluation among young adults. For those with elevated social anxiety, these environments may be especially salient because they provide frequent opportunities for social comparison. Although upward social comparison on social media has been linked to poorer emotional outcomes, less is known about its experimental effects among socially anxious young adults or whether upward and downward comparison have distinct effects that extend to later socially evaluative situations. The present study examined these questions in 84 socially anxious young adults randomly assigned to view simulated Instagram feeds eliciting upward comparison, downward comparison, …

Modeling And Generating Trustworthy Speech, Yuwen Yu

Dissertations, Theses, and Capstone Projects

As virtual agents become increasingly integrated into everyday communication, trust has become essential for effective human-AI interaction. Although recent advances in natural language generation and speech synthesis have significantly improved fluency and intelligibility, most systems are not designed to control how trustworthy they are perceived. As a result, a mismatch can emerge between perceived trustworthiness and actual system capability, leading to over-trust or under-trust. While trust is critical for meaningful interaction, current text-to-speech (TTS) systems are primarily optimized for naturalness and intelligibility rather than calibrated trustworthiness.

This dissertation investigates the perceptual foundations of trust in both human and synthesized speech …

Individual Intellectual Humility As A Predictor Of Perceived Information Sharing And Perceived Shared Leadership, Mary Beth Schroeder

Dissertations, Theses, and Capstone Projects

Cross-functional problem-solving teams are often assembled to address complex challenges by combining members’ distinct knowledge, ideas, and leadership capabilities. Yet teams do not always capitalize on these collective resources, because team members do not share the information they uniquely possess. This tendency to withhold information may be lessened by intellectually humility, a personality trait marked by a desire to close gaps in one’s knowledge and openness to what others contribute.

This study was originally designed to examine whether team intellectual humility relates to team creativity through information sharing and shared leadership. However, because of changes in the leadership development program …

Opportunities For Learning Through Object Exploration During Early Physical Therapy: Physical Therapists’ And Caregivers’ Assistance And Interference Behaviors, Michele Goncalves Maia

Dissertations, Theses, and Capstone Projects

Early physical therapy (EPT) for infants with motor delays has traditionally emphasized motor milestone acquisition, yet growing evidence indicates that motor and cognitive development are fundamentally interconnected. Grounded in embodied cognition and developmental cascade theories, this dissertation conceptualized object exploration as a primary mechanism through which infants learn during EPT and examined how intervention approaches and adult behaviors shape opportunities for object exploration. Using retrospective analyses of video-recorded EPT sessions, two studies investigated how intervention approaches and adult behaviors influence infants' opportunities to learn through object exploration. Study 1 compared object exploration in the START-Play (SP) intervention and Usual Care …

Sedentary Behaviors And Functional Disability Among Chinese Older Adults (2008–2018): Evidence Including Mahjong, Yen-Han Lee, Yen-Chang Chang, Minzhi Ye, Cai Xu

School of Social Work Faculty Publications

Purpose: This study examined how different types of sedentary behavior relate to changes in functional disability, measured by activities of daily living (ADL) and instrumental activities of daily living (IADL), among Chinese older adults.

Major findings: Using data from 17,939 participants in four waves (2008–2018) of the Chinese Longitudinal Healthy Longevity Survey (CLHLS), sedentary behavior was categorized into four types: none, playing mahjong only, combining these with other sedentary activities, and other activities alone (e.g., reading and watching TV). Cox two-state regression models estimated the hazard of transitioning in ADL and IADL disability. Engaging in sedentary behaviors was generally …

Vicarious Trauma: The Psychological Impact On Counsellors And Psychotherapists Working With Survivors Of Sexual Abuse., Deborah Down, Alison Bacon

School of Psychology

Background: Vicarious trauma (VT), the psychological distress that occurs from exposure to the trauma of others, is prevalent among therapists, but has not previously been explored in those working specifically with survivors of sexual trauma. This qualitative study explores counsellors‘ and psychotherapists‘ experiences of VT when working with survivors of sexual abuse. Method: Semi-structured interviews uncovered complex emotional and psychological impacts, highlighting how exposure to traumatic sexual abuse narratives can affect counsellors‘ and psychotherapists‘ wellbeing, and professional and personal identity. A reflexive thematic analysis was conducted. Results: Four key themes were identified. (1) The Impact of VT reveals the emotional …

Green Information Systems Adoption And Business Outcomes In Ugandan Smes: An Extended Theory Of Planned Behaviour Approach, Sonny Juma Nyeko, Samali Mlay, Cosmas Ogenmungu, Abdallah Ibrahim Nyero

Business Management Review

The study assesses the relationship between TPB antecedents and GIS business outcomes in SMEs, using an expanded TPB framework. Researchers gathered data from SMEs via a survey and analysed it using PLS-SEM. The framework used in the study explains 58.5% of the differences in GIS business outcomes. The results reveal that subjective norms, attitude, benefits, and obstacles are significant predictors of GIS business outcomes such as ecological IT practices, although perceived behavioural control displays an insignificant negative relationship. The study extended the TPB model by incorporating GIS benefits and GIS obstacles as additional factors influencing GIS adoption, business outcomes, …

Longstanding Mental Representations Of Familiar Faces, Sarah Laurence, A. Mike Burton, Camilla During, Jennifer Pink, Lucy Wilson, Mila Mileva

School of Psychology

As we recognise people we know over many years, their faces can change, sometimes profoundly, and yet we continue to recognise them with ease. How do we update our representations over time? We present four pre-registered experiments to examine this. In Experiment 1, using likeness ratings and speeded name verification, fans of a long-running TV soap opera demonstrated that their representations of the characters’ faces were weighted towards their most recent encounters – when the characters were oldest. While we initially hypothesised that this was due to recency, Experiment 2 showed this not to be the case. When new participants …

Is The Crisis Over? Fostering Innovative Work Behavior In Response To The Constant Pressure Of Resource-Deficiency For Street Level Bureaucrats: The Impact Of Psychosocial Safety Climate, Teamwork, And Work Engagement, Yvonne Brunetto, Matthew Xerri, Geremy Farr-Wharton

Research outputs 2022 to 2026

There is conflicting evidence about the pathways Street Level Bureaucrats’ (SLBs’) use to engage Innovative Work Behavior (IWB). This study uses Street Level Bureaucrat (SLB) and Conservation of Resources (COR) to examine the extent to which SLBs’ work engagement and/or burnout mediates the relationship between Psychosocial Safety Climate (PSC) and teamwork, and IWB. The methods comprised a sample of 259 healthcare SLBs (doctors, nurses, allied health) collected at two times, and analyzed using structural equation modeling. The results show that the variance of PSC and teamwork explained a third of engagement, and engagement-burnout mediated the impact of PSC and teamwork …

Curiosity In Tourism: A Review And Future Directions, Sten Langmann, Pieter Jan Bezemer, Eerang Park, Sangkyun Kim

Research outputs 2022 to 2026

Curiosity increasingly attracts attention in tourism research. However, the field remains conceptually fragmented around what curiosity is and how it works, often pointing to related yet different understandings of the concept. Drawing on an in-depth analysis of 61 peer-reviewed articles, we aim to build a more coherent agenda for future research by answering two core questions: how has curiosity been conceptualised and studied in tourism research, and what gaps and directions emerge from the literature? The analysis reveals that curiosity has been studied in four primary ways in tourism research: an innate motivational driver, a situational mediating state, an outcome …

Underfunded And Undervalued: Community-Based Health Promotion Practitioners’ Experiences Of Western Australia’S Prevention Sector, Ruth M. Wallace, Leesa N. Costello, Elizabeth J. Cook

Research outputs 2022 to 2026

Prevention is a central policy focus of contemporary health promotion, offering cost-effective strategies to reduce disease burden and improve population well-being. Despite this, Australia allocates a small proportion of its health budget to prevention, with funding models characterized by short-term cycles and competitive tendering. While the consequences for public health are well documented, the impact on the health promotion workforce remains underexplored. Workforce health and stability are critical for program delivery, ethical practice, continuity of relationships with communities, and the capacity to sustain long-term prevention efforts. This qualitative study examined the experience of 19 community-based health promotion practitioners in Western …

Disrupted Trajectories: Covid-19, Transnational Youth Mobility And Unequal Transitions To Adulthood, Simon Chambers, Anita Harris, Loretta Baldassar

Research outputs 2022 to 2026

While the impact of COVID-19 on youth development has been widely studied, less is known about its effects on transnationally mobile young adults. This longitudinal study of Australian outbound and inbound mobility examines how the pandemic disrupted this population's experiences abroad as they navigated transitions to adulthood. It draws on two waves of survey data collected using a convenience sample between July 2020 and September 2022. Our findings reveal that COVID-19 presented significant challenges to young adults living away from home, with disruptions to their future plans, social connections, and well-being. However, these impacts were not uniform. The pandemic magnified …

Rank, Degrading Treatment, And The Italy-Albania Agreement, Jamal Barnes, Obed Adonteng-Kissi

Research outputs 2022 to 2026

In November 2023, Italy signed a five-year agreement with Albania to transfer asylum seekers intercepted in international waters by Italian vessels to Italian-run detention centres in Albania for asylum processing and deportation. The agreement has been controversial and raises several human rights issues. This article examines these human rights concerns and argues that the agreement is degrading by design. Analysing policy documents, legal cases, speeches, international human rights and refugee law, and philosophical and legal scholarship on the concept of degrading treatment, this article argues that the cumulative effect of subjecting people to unnecessary suffering, discrimination, and dehumanisation creates a …

The Impact Of Stigma On The Mmpi-3 Scores Of An Indo-Caribbean Community Sample, Julia Persaud-Naipaul

Theses and Dissertations

Evaluation of personality and psychological disorders is accomplished through the use of psychometric measures. However, tests require interpretation of test responses using a normative criterion based on a particular population that may not fully consider the effect of cultural influences on an individual’s level of willingness to report psychological difficulties. For example, individuals in collectivistic cultures may not be as willing to self-report problems because mental illness is often perceived as a source of embarrassment and shame. One culturally unique population that has been overlooked in psychological assessment is the Indo-Caribbean population. Their specific cultural values, beliefs, attitudes, and practices …

Towards Human-Centered Digital Health Interventions, Kristin M Kostick-Quenet, Eric A Storch

Center for Medical Ethics and Health Policy Staff Publications

This article discusses the potential of digital health interventions (DHIs) in mental health care, emphasizing the importance of designing them to foster genuine humanistic care. It highlights current challenges in measuring engagement and outcomes, advocating for integrating human-centered endpoints such as dignity, autonomy, and therapeutic alliance into evaluation frameworks. The authors call for mechanistic research to identify effective engagement strategies and context-specific implementation approaches. Ultimately, successful DHIs should demonstrate both clinical efficacy and the preservation of humane, person-centered care, ensuring ethical and meaningful mental health support through technology.

“I Really Like Being On The Floor, Because I Spend All The Time In My Chair”: Children With Disabilities’ Experiences Of Physical Activity In School, Katherine Gulliver, Rachel Knight Lozano, Kathrin Paal

School of Law, Humanities and Social Sciences

Children with multiple disabilities often encounter significant barriers to participating in physical activity, impacting not only their physical health but also their overall experience in school. This study places the voices of four children at the centre of their own research, exploring their lived experiences of participating in physical activity in school. Using Clark’s (2017) Mosaic approach, this child-centred participatory study shows how children take part and engage with physical activity as part of their school day. Using videos and photography, child-led tours and ethically sensitive conversations with researchers, children shared a range of opportunities for enjoyment, exploration and interactions …
