Optimal closed-loop robust rendezvous guidance with the observability constraint of angles-only navigation
Authors: Du Ronghua , Liao Wenhe , Zhang Xiang
Published: April 2023

This paper proposes an optimal closed-loop rendezvous guidance algorithm with the observability constraint of angles-only navigation using robust convex optimization. First, the relative dynamics equation is established based on the well-known Clohessy–Wiltshire (CW) equation, and the measurement equation which includes a set of azimuth and elevation is also established. Then, a geometrical observability analysis is introduced to analyze the observability of angles-only navigation. And then, taking the geometrical observability of angles-only navigation as the variable, taking the total fuel cost as the optimization objective, and considering other various constraints such as relative motion and thrust magnitude constraints. And then, the mathematical expression of the closed-loop rendezvous guidance with the observability constraint of angles-only navigation is established. A robust convex optimization method is introduced to solve the problem proposed in real time online. Finally, the performances of the proposed algorithm are analyzed by means of numerical simulation, which verifies the effectiveness of the algorithm proposed in this paper.
What Aspects of School Climate Matter Most to Asian Teachers’ Job Satisfaction and Well-Being? Evidence from the TALIS 2018
Authors: Nalipay Ma. Jenina N.
Published: April 2023

Background/Context:

The level of satisfaction and well-being teachers experience are important determinants of teaching effectiveness and their decision to stay in the profession. Although school climate is generally associated with teacher outcomes, identifying the aspects that matter most to teacher satisfaction and well-being could contribute to the formulation of more targeted policies.

Purpose/Objective/Research Question/Focus Of Study:

The present study focused on the relatively underexplored samples of teachers from five selected Asian societies (Japan, South Korea, Shanghai, Singapore, and Taipei [total n = 30,386]) to identify the aspects of school climate that matter most to their job satisfaction and well-being.

Research Design:

A cross-sectional study was conducted using data from the Teaching and Learning International Survey 2018. Multilevel analyses were performed to find out which teacher- and school-level school climate indicators predict teachers’ job satisfaction and well-being in the five Asian societies.

Conclusions/Recommendations:

Disciplinary climate and participation among stakeholders were consistent predictors of both job satisfaction and workplace well-being and stress, whereas teacher–student relations consistently predicted job satisfaction across the societies. Teacher-level, compared to school-level, school climate indicators were better determinants of Asian teachers’ job satisfaction and well-being in all five societies. This suggests that greater attention should be given to proximal aspects of school climate and teachers’ perceptions about it. These findings can be considered when formulating policies in these contexts.
Reinventing the Diplomat: Isabelle Stengers, Bruno Latour and Baptiste Morizot
Authors: Janicka Iwona
Published: April 2023

Recent debates within broadly considered posthumanities have been populated by various conceptual personae. One such figure is the diplomat. First proposed in this context by Isabelle Stengers in her Cosmopolitics series, the diplomat has been subsequently taken up and further developed by Bruno Latour, particularly in his AIME project, and most recently by Baptiste Morizot in Les Diplomates. This article traces the metamorphosis of this conceptual character in the work of Stengers, Latour and Morizot. As all three versions are relatively close to each other, this article proposes three companion figures: the heretic (for Stengers), the designer (for Latour) and the amateur (for Morizot) that allow us to carefully examine the differences between, and the specific stakes of, each iteration of the diplomat. Furthermore, the article critically evaluates the theoretical pertinence of the diplomat figure for each philosopher’s project and considers its potential for thinking about the future of our more-than-human worlds.
Did outside directors’ firm-specific accumulated knowledge benefit the firm’s stock performance during COVID-19?
Authors: Naidu Dharmendra , Ranjeeni Kumari
Published: April 2023

We examine whether outside directors’ firm-specific accumulated knowledge in the forms of human and internal social capital benefitted the firm during COVID-19. Using a sample of 754 US firms during the COVID-19 collapse period, we find an inverted U-shaped relation between outside directors’ average board tenure and cumulative excess stock returns. Our result suggests that firms experienced optimal cumulative excess stock returns during COVID-19 when outside directors’ average board tenure is 10 years. We also find that the curvilinear relation is profound for outside directors with more internal social capital, suggesting that outside directors’ internal social capital plays a prominent role in enhancing board effectiveness during a crisis. Furthermore, we use several robustness checks to confirm the results.

Thinking Beyond the Gas Tax: A Case Study Analysis of a Road User Charge System for Texas
Authors: Steadman Maxwell , Kuzio Jacqueline , Prieto Bill , Glover Brianne
Published: April 2023

Surface transportation funding in the U.S. is heavily reliant on fuel taxes that are becoming less effective as fuel efficiency increases and alternative fuel vehicles become more common. This report examines the benefits and challenges of using road user charges (RUCs) of various types to address this issue, before analyzing the potential revenue from a hypothetical RUC on four urban corridors within Texas. Common issues for RUCs are discussed, which include privacy, interstate coordination, and program administration. A range of possible options for RUCs are discussed, followed by an analysis of four corridors in the following counties: Bexar, Collin, Harris, and Lubbock. Data from TTI’s Urban Mobility Report on VMT were utilized along with vehicle registration data from TTI’s TRENDS model to estimate an average miles per gallon for each county based on the local fleet. Three scenarios were then developed including a revenue recovery scenario, a variable pricing scenario, and a carbon tax scenario. This report concludes with a discussion of the scenario results. Specific challenges and barriers for each scenario are discussed along with a discussion of the data sources and privacy trade-offs.
The Impact of Professional Development on Data-Based Decision-Making for Students With Extensive Support Needs
Authors: Ruhter Lindsay , Karvonen Meagan
Published: April 2023

There is evidence that data-based decision-making (DBDM) can improve outcomes for a wide range of students. However, less is known about how special education teachers are trained to use data to inform instruction that targets academic progress for students with extensive support needs (ESN). The purpose of this systematic literature review was to describe the intervention literature on the impact of professional development (PD) on teachers’ use of DBDM for students with ESN. Eight studies were identified. The DBDM interventions primarily targeted teachers’ decision-making related to instruction in individualized curricular goals or academics in functional contexts and were driven by data on isolated skills and concrete decision rules. All but one study documented some improvement in teacher or student outcomes after DBDM PD. Suggestions for future research, limitations of this review, and implications for practice—including student progress in the general education curriculum—are discussed.
The Role of Family Ethnic Socialization and Generational Status in White Adolescents’ Ethnic-Racial Identity Development
Authors: Ison Ashley , Satterthwaite-Freiman Megan , Sladek Michael R. , Umaña-Taylor Adriana J.
Published: April 2023

Family ethnic socialization (FES) is a critical component of youth ethnic-racial identity (ERI) development. However, little research has focused on FES experiences amongst White families. The current study applied a convergent mixed methods design to investigate how immigration generational status (i.e., number of U.S.-born parents and grandparents) was associated with FES within White American families and the extent to which that informed adolescents’ ERI development. Utilizing survey data for White adolescents’ ( N = 532) self-reported FES experiences and ERI exploration and resolution, quantitative path analyses testing for mediation indicated that, as adolescents reported more family members born in the U.S., their FES experiences were lower and, in turn, their ERI exploration and resolution were also lower. FES fully mediated the relation between generational status and their ERI exploration and resolution. A theoretical thematic analysis of focus group data from a subsample of participants offered insights into how White adolescents described their FES experiences, illustrating the integral role of parents and grandparents for learning about their ethnic heritage, school’s role in facilitating FES, and various methods of maintaining familial collective cultural memory. The current study offers preliminary insights into FES among White families and identifies new questions for exploration future research.
Peer Victimization and Psychosocial Adjustment among Children of Parents with Physical Disabilities in China: A Comparative Study
Authors: Zhang Huiping , Cao Ruixin , Pang Shijie , Wang Yang
Published: April 2023

This study investigated whether the children of parents with physical disabilities endured higher levels of peer victimization. Particularly, this study focused on the mediating effects of peer victimization in the relationships between parental disability and both the emotional symptoms and prosocial behaviors exhibited by their children. Data were obtained from a survey on health and mental health among children and adolescents from disadvantaged families. The survey was conducted by Renmin University of China from August to September 2018 using multistage probability sampling method. The sample in this study included 716 adolescents, of whom 390 had at least one parent with physical disabilities and reported more severe peer victimization. In contrast to respondents who did not have parents with physical disabilities, these adolescents experienced more emotional symptoms and engaged in fewer prosocial behaviors. Furthermore, the analysis showed that 15.16% of the total effect of parental disability on emotional symptoms was mediated by peer victimization, which had a nonsignificant mediating effect in the relationship between parental disability and prosocial behaviors. These findings can inform practitioners who aim to help children of parents with physical disabilities improve their coping strategies and social skills to manage peer relationships. Moreover, these results highlight the importance of establishing an inclusive school and community environment to reduce social stigma and peer victimization toward children from disadvantaged families.

Authors: Grocott Lauren R. , Avery Katie , Medenblik Alyssa M. , Romero Gloria , Edwards Katie M. , Stuart Gregory L. , Shorey Ryan C.
Published: April 2023

Given the growing body of research seeking to examine adverse childhood experiences (ACEs) and intimate partner violence (IPV) among sexual and gender minority (SGM) individuals, Institutional Review Boards must consider whether participating in violence research is emotionally distressing for SGM people. Yet, little research has studied SGM participants’ reactions to participating in research on ACEs, IPV, and minority stress. Thus, the current study examined reactions, including negative emotional reactions, to participating in violence research among SGM young adults. In total, 230 participants who self-identified as a sexual minority (30.1% also identified as a gender minority) in a dating relationship completed a cross-sectional assessment on ACEs, IPV (including identity abuse victimization and perpetration), minority stress (i.e., internalized homo/bi/transphobia), and reactions to research participation. Results indicated that participants identifying as a gender minority had significantly higher negative emotional reactions to study participation compared to cisgender participants, but this increase among gender minority individuals was small. In addition, gender minority participants and those with higher minority stress (i.e., internalized trans/bi/homo-negativity) and ACEs reported significantly higher negative emotional reactions to participation. Furthermore, gender minority participants scored worse on a scale indicating appreciation for contributing to research. Finally, reporting IPV victimization and perpetration was not associated with negative emotional reactions. Findings suggest that questions assessing minority stress and negative childhood experiences may be more emotionally salient or stressful for gender minority participants compared to questions measuring IPV.
Applying GST to Understand and Contextualize Bullying: A Conjunctive Analysis of Case Configurations
Authors: Paez Gabriel R. , Briones Robinson Rhissa
Published: April 2023

Drawing from Agnew’s general strain theory, this study examines whether certain risk factors have a consistent effect across different situational contexts that characterize bullying perpetration. A conjunctive analysis of case configurations was conducted to examine and identify situational factors that increase adolescents’ risks for bullying perpetration using data from the 2019 Minnesota Student Survey. Results from a sample of 166,176 U.S. adolescents show that (1) incidents of traditional bullying perpetration cluster significantly among dominant situational profiles; (2) students most likely to be bullies experience victimization, but students least likely to bully their peers rarely experience bullying victimization; and (3) being a victim of traditional bullying can increase the chances of traditional bullying perpetration in some situational contexts, but can have almost no influence on perpetration in other contexts. Current findings are discussed considering existing bullying scholarship and recommendations for policy and future areas of research are presented.
Design and stability analysis of a nonlinear controller for MRI-compatible pneumatic motors
Authors: Li Mengtang
Published: April 2023

Among permissible magnetic resonance imaging (MRI) compatible actuators for surgical robots, turbine-based pneumatic motors are noticeably favorited due to its compact size, simpler structure, fast additively manufacturability, and continuous bidirectional motion ability. Yet, the system dynamics of pneumatic motors, especially pneumatic nonlinearity, is often neglected and simple PID control is used, resulting in low system bandwidth (~0.5 Hz). To tackle this obstacle, this paper proposes a model-based nonlinear control method for MRI-compatible pneumatic motors. Dynamic models for a pneumatic motor previously designed by the author are developed first, followed by establishment of the nonlinear feedback controller. An error based Lyapunov candidate function is designed and mathematically proved to be globally uniformly asymptotically stable, guaranteeing desired accuracy. Experiment control tests demonstrate that the proposed control method can achieve satisfactorily better tracking accuracy than a conventional model-independent PID controller with respect to amplitude attenuation and phase delay.
Research on interior noise optimization of minibus based on vibration transfer path analysis using super element method
Authors: Xiao Shenghao , He Jie , Li Yumei , Xu Gang , San Yunlong
Published: April 2023

In this paper, aiming at the problem of excessive low-frequency noise in a minibus, the SEM (Super Element Method) was applied to the NVH (Noise, Vibration and Harshness) dynamics simulation analysis of the vehicle, and the vibration and noise control schemes were proposed from the aspect of vibration transfer path to improve NVH performance. First, the relationship and difference between SEM and LFEM (Legacy Finite Element Method) were elaborated theoretically. Afterward, the legacy finite element model of the full vehicle, which comprehensively considered all related components such as BIW (Body In White), chassis, door covers, body accessories and interior and exterior trims, was established based on LFEM. Furthermore, the subsystems of legacy finite element model of the vehicle were divided into super elements based on SEM, and the differences between SEM and LFEM in model processing were discussed in detail. In addition, the modal analysis and frequency response analysis of the full vehicle were carried out by LFEM and SEM respectively, and the computational results were compared with the testing results to verify the simulation accuracy and feasibility of the SEM in solving the vehicle body dynamics problems. Meanwhile, through the comparison of simulation analysis process of SEM and LFEM in practical case, the advantages of SEM compared with LFEM were discussed in terms of computational efficiency and storage space occupied. Finally, the stiffness optimization schemes of rubber bushing in the middle of driveshaft were proposed to improve vibration and noise from the aspect of vibration transfer path, and the testing results verified the effectiveness of the optimization schemes in reducing the low frequency noise inside the vehicle. The study concluded that SEM had obvious advantages over LFEM in terms of computational efficiency and storage space occupied, while ensuring the computational accuracy basically consistent with that of LFEM.
Investigation of probable squat growth from initial surface cracks in rails using a three-dimensional rollover simulation
Authors: Gschwandl Timna J , Antretter Thomas , Künstner David , Scheriau Stephan , Daves Werner
Published: April 2023

Squats are rather complex failure mechanisms in rails and challenge railway operators all over the world, thus calling for a detailed investigation of squats by means of finite element analysis to locate the initiation and propagating mechanisms. In this work, a cyclic three-dimensional (3D) finite element model of a wheel-rail contact including an initial penny-shaped defect is used. This work presents the implementation of the starting penny-shaped crack in the rail for a wheel-rail simulation by utilising a submodel strategy. Moreover, viable evaluation options are shown. In the future, this set-up will help to assess multiple crack positions and possible squat growth mechanisms.
A PID controller based on the processor utilization artifact within a real-time multitask control system
Authors: Zakaria Sahraoui
Published: April 2023

Codesign of control and scheduling systems is commonly used in the literature to address scheduling artifacts such as latencies and jitters. However, As controllers’ designs remain unchanged and fail to express any concerns regarding this matter, it becomes challenging to quantify the quality of control and its trade-off with resource utilization while adapting control or scheduling settings at runtime. In the present article, we propose a new proportional–integral–derivative (PID) controller design for the problem of scheduling artifacts. Based on our prior work, the latency processor utilization is revealed as a hidden artifact for the control deterioration when developing new predicted PID controller terms. This artifact effect is proven analytically using a codesign task model and considering an extrapolated measurement. The effectiveness of the proposed solution is assessed with a benchmark system and compared with previous works.
Five Misconceptions About Consensually Nonmonogamous Relationships
Authors: Moors Amy C.
Published: April 2023

A sizeable minority of people engage, or have engaged, in some form of consensually nonmonogamous relationship (explicit mutual agreements to have multiple emotional, romantic, and/or sexual relationships). This article draws on current scientific knowledge to address five misconceptions about consensual nonmonogamy: (a) There is a “type” of person who engages in consensual nonmonogamy; (b) people engage in consensual nonmonogamy to “fix” their relationships issues and these relationships; (c) are low in quality, (d) promote the spread of sexually transmitted infections, and (e) are harmful to children. Yet, upon empirical scrutiny, popular misconceptions about consensual nonmonogamy are either not what they seem or, in many cases, contrary to people’s beliefs.
Honoring Rosemary Radford Ruether: Feminism Was Her Liberation
Authors: Yugar Theresa A.
Published: April 2023

Feminist liberation theologian Rosemary Radford Ruether was a prophetic and progressive voice for women in the Roman Catholic Church. Although feminism was only one aspect of her scholarship, it resulted in her theological contributions being dismissed in the Church. Rosemary’s challenges in the Church were primarily her biological sex and her feminist perspective. This clashed with male clericalism, and the patriarchal hierarchy of the Church. Rosemary was also highly critical of the First Vatican Council’s declaration about papal infallibility. In the twenty-first century, Rosemary Radford Ruether should be recognized as a Doctor in the Church for her groundbreaking scholarship, which reclaims women’s theological perspectives as a starting point for doing theology, and for her renewed vision of a more “authentic Catholicism.”
Rosemary Radford Ruether’s Global Scope in Interfaith Reconciliation
Authors: Robinson Sarah
Published: April 2023

Rosemary Radford Ruether’s life work demonstrates in books, conferences, and courses her commitment to facilitating dialogue to advance the well-being of women, not as a secular feminist, but as a feminist theologian providing self-critical attention within the Christian community. Her work is an exemplar of redemptive recovery from harmful thinking and the concrete contexts where harmful thinking becomes systematized and institutionalized. Drawing primarily from her Buddhist-Christian dialogues with Rita Gross, this essay provides a series of vignettes to demonstrate Ruetherian methods for self-critical Christian participation in pluralistic encounter.

Becoming the right musician for the job: Versatility, connectedness, and professional identities during personalized, online music-making in hospital maternity wards
Authors: Shaughnessy Caitlin , Hall Andrew , Perkins Rosie
Published: April 2023

The beneficial potential for music in hospital contexts is well established, with research showing that music can promote patient well-being and support recovery. However, less attention has been paid to the ways in which musicians’ practices and professional identities are informed by working in hospital settings. As arts-and-health approaches continue to proliferate, it is essential to recognize the values, emotional labor, and skills associated with these approaches through understanding the experiences of practitioners. As part of an international collaboration led by Hanze University in the Netherlands, the ProMiMiC project explores the professional development of musicians and nurses through person-centered music-making in hospital settings. The current study focused on five conservatoire-trained musicians’ delivery of personalized music-making via Zoom in a hospital maternity setting in London during the COVID-19 pandemic. Their experiences of adapting to the new context, and the impacts on their personal and professional development, were explored using reflective journals, group discussions, and semi-structured interviews. The data were interpreted using the theoretical lens of vocational habitus to examine the skills and dispositions required to be the right musician for this job. Qualitative synthesis revealed the musicians’ developing musical values as they adapted to the online maternity setting, highlighting the centrality of communicative and musical versatility as well as the ability to connect and empathize through music. The findings offer insights into possible ways of supporting emerging music practitioners in healthcare settings and emphasize the imperative for higher music education to prepare and train musicians for this type of work.
Replication of the music preference (MUSIC) model and evaluation of its association with personality and autistic traits
Authors: Chee Zhong Jian , Leung Yvonne , de Vries Marieke
Published: April 2023

Music preferences have consistently been found to follow a five-factor structure (i.e., Mellow, Unpretentious, Sophisticated, Intense, and Contemporary, in short MUSIC), in the West. These factors are associated, in turn, with the Big Five personality traits. However, the stability of this structure and its association with personality in non-Western cultures are underexplored. Moreover, behavioral traits other than personality traits might relate to music preferences. High systemizing traits, as often seen in people with autism, tend to be associated with a preference for Intense music. However, whether this generalizes to autistic traits in the general population remains unclear. The current study therefore attempted to examine the five-factor MUSIC model and test its association with Big Five personality traits and autistic traits in an online study of Malaysians. A total of 444 participants, of whom 59.7% were of Chinese ethnicity, rated their preference for 50 brief musical excerpts and completed the Ollen Musical Sophistication Index, the Ten-Item Personality Inventory, and the Autism-Spectrum Quotient-28. The original MUSIC model was partially replicated with virtually identical Sophisticated and Intense factors. However, once age, gender, and musical sophistication were controlled for, most of the previously reported associations between Big Five personality traits and music preferences were not found. Instead of a positive association between autistic traits and Intense music, a negative association was found between autistic traits and Contemporary music. These findings partially support the validity of the MUSIC model in Malaysia and highlight the importance of undertaking research on music preferences in non-Western contexts.
Family Diversity and Business Start-Up: Do Family Meals Feed the Fire of Entrepreneurship?
Authors: Wang Wei , Eddleston Kimberly A. , Chirico Francesco , Zhang Stephen X. , Liang Qiaozhuan , Deng Wei
Published: April 2023

Integrating the family embeddedness perspective with research on commensality and family meals, we develop a framework that explains why some families are more likely to fuel entrepreneurship than others. Inspired by the diversity literature and the role of the Chinese Confucian culture in shaping family dynamics, we explore how two demographic (i.e., age and gender) and two knowledge-based (i.e., education and industry) sources of diversity within family households predict a family member starting a business. We further theorize that these relationships are contingent on the frequency of family meals, as family meals serve as a conduit for how family diversity affects entrepreneurship by providing the setting where socialization and interaction take place. Using data from a representative sample of 8,162 individuals via the China Family Panel Studies in the 2014 to 2018 period, our findings demonstrate that although greater age and gender diversity hamper entrepreneurship, family meals “feed the fire” of entrepreneurship for families with greater industry and education diversity.
A Social Network Analysis of Publishing Networks in the “Big 5” Journals in Criminology and Criminal Justice
Authors: Fenimore Danielle M. , Roche Sean P. , Jennings Wesley G. , Heinen Remy
Published: April 2023

Prior research has frequently employed various methods for investigating issues surrounding publication productivity and authorship, including examinations of the number of co-authors in peer-reviewed journal articles and the order of authorship. Relying on 5 years of data from publications from the “Big 5” journals in criminology and criminal justice (i.e., Criminology, Journal of Research in Crime & Delinquency, Journal of Quantitative Criminology, Crime & Delinquency, and Justice Quarterly), the current study extends this extant research by providing a social network analysis of publishing networks. Results are consistent with previous findings, suggesting that publishing networks are largely decentralized, although key networks and definitive leaders in these networks exist as well. In addition, several authors were identified that have significant leverage over the publishing networks. Study limitations and directions for future research are also discussed.
Expressions of nonlocal quantities and application to Stoneley waves in weakly nonlocal orthotropic elastic half-spaces
Authors: Anh VTN , Vinh PC
Published: April 2023

In this paper, we introduce a novel model of nonlocal elasticity, called the weakly nonlocal elasticity, and provide explicit expressions of nonlocal quantities for harmonic plane waves propagating in the weakly nonlocal elastic solids. Then, we apply these expressions to investigate the propagation of Stoneley waves along the interface between two weakly nonlocal orthotropic elastic half-spaces. The half-spaces may be compressible or incompressible, and they are in welded contact. Our main aim is to derive explicit dispersion equations of Stoneley waves. First, we derive the explicit dispersion equation for the compressible case (when two half-spaces are compressible) using the surface impedance matrices of half-spaces. Then, the explicit dispersion equations for the incompressible cases (at least one half-space is incompressible) are obtained using the incompressible limit method. The simple and immediate derivation of these equations proves the convenience of the incompressible limit method. Some numerical examples are carried out to examine the effect of nonlocality and incompressibility on the Stoneley wave velocity.
Micro-Level Mechanisms to Support Value Co-Creation for Design of Digital Services
Authors: Tuunanen Tuure , Lumivalo Juuli , Vartiainen Tero , Zhang Yixin , Myers Michael D.
Published: April 2023

This study identifies micro-level value co-creation mechanisms that support the design of digital services. As services are now becoming digital—or at least digitally enabled—how to design digital services that enable value co-creation between a service provider and customers has become an increasingly important question. Our qualitative research study provides one answer to this question. Based on 113 in-depth laddering interviews analyzed using interpretive structural modeling, our study shows that value co-creation mechanisms differ between business-to-business and customer-to-customer digital service types. We identify five mechanisms to support value co-creation in the design of digital services: (1) Social use, (2) Customer orientation and decision making, (3) Service experience, (4) Service use context, and (5) Customer values and goals. We claim that firms can readily utilize these mechanisms to improve their customers’ service experiences.

Published: April 2023

This mixed-methods study aimed to explore the experiences and goals of Māori parents and whānau (families) caring for young autistic children. Data were collected via a rōpū kōrero (focus group) and an online questionnaire, with a total of 33 parents and whānau participating in at least one phase of the study. Reflexive thematic analysis was used to analyse rōpū kōrero data with findings used to inform the design of an online questionnaire. Questionnaire responses were summarised using descriptive statistics. Results indicate that experience and perceived helpfulness of supports varied across participants. Communication and values-based goals were a high priority for most participants, and most rated cultural goals as important. Findings highlight the value of considering parent and whānau voices, especially those from Indigenous communities.
Beyond binaries: mixed-blood Indigenous inequalities
Authors: Dicks Heather
Published: April 2023

This article explores existing research related to mixed-blood Indigenous individuals in an effort to reveal a more complete picture of social inequality that exists within and between the binary categorization of Indigenous and non-Indigenous within Canada. Tracing a line through past and present discriminatory assimilationist policies, this article reveals the pervasive challenges associated with living as a mixed-blood Indigenous person in this country. Marked by a perpetual struggle to gain recognition from both Indigenous and settler populations, individuals living within this marginal identity face a structure of inequality that is little explored in contemporary research literature.
Etuaptmumk (Two-Eyed Seeing) in Nature’s Way-Our Way: braiding physical literacy and risky play through Indigenous games, activities, cultural connections, and traditional teachings

Published: April 2023

Growing philosophical and empirical evidence shows that physical literacy and risky play enriches movement opportunities, while also fostering increased physical activity, wholistic health, and wellness across the lifespan. However, physical literacy and risky play have typically been theorized and practiced from a western worldview. In response, Nature’s Way-Our Way is an initiative designed to ground physical literacy and risky play in Indigenous games, activities, cultural connections, and traditional teachings, as enacted in Early Childhood Education Centres across Saskatchewan, Canada. This article explores Nature’s Way-Our Way’s theoretical underpinnings of Etuaptmumk (Two-Eyed Seeing), adopted to braid together the strengths of Indigenous Knowledges with western knowledge through practices of Indigenous métissage (land and story-based approaches to curriculum informed by relationality). Providing examples of culturally rooted resources, this article shows how the Nature’ s Way-Our Way initiative supports Indigenous self-determination and sovereignty to foster increased physical activity, wholistic health, and wellness across the lifespan.

Published: April 2023

The Parkinson disease (PD) is the second most common neurodegenerative disorder affecting the central nervous system and motor functions. The biological complexity of PD is yet to reveal potential targets for intervention or to slow the disease severity. Therefore, this study aimed to compare the fidelity of blood to substantia nigra (SN) tissue gene expression from PD patients to provide a systematic approach to predict role of the key genes of PD pathobiology. Differentially expressed genes (DEGs) from multiple microarray data sets of PD blood and SN tissue from GEO database are identified. Using the theoretical network approach and variety of bioinformatic tools, we prioritized the key genes from DEGs. A total of 540 and 1024 DEGs were identified in blood and SN tissue samples, respectively. Functional pathways closely related to PD such as ERK1 and ERK2 cascades, mitogen-activated protein kinase (MAPK) signaling, Wnt, nuclear factor-κB (NF-κB), and PI3K-Akt signaling were observed by enrichment analysis. Expression patterns of 13 DEGs were similar in both blood and SN tissues. Comprehensive network topological analysis and gene regulatory networks identified additional 10 DEGs functionally connected with molecular mechanisms of PD through the mammalian target of rapamycin (mTOR), autophagy, and AMP-activated protein kinase (AMPK) signaling pathways. Potential drug molecules were identified by chemical-protein network and drug prediction analysis. These potential candidates can be further validated in vitro/in vivo to be used as biomarkers and/or novel drug targets for the PD pathology and/or to arrest or delay the neurodegeneration over the years, respectively.
Oxidative Stress Underpins Clinical, Social, and Genetic Risk Factors for Atherosclerotic Cardiovascular Disease
Authors: Mewborn Emily , Stanfill Ansley
Published: April 2023

Background:

Atherosclerotic cardiovascular disease (ASCVD) remains the leading cause of death worldwide and is poorly predicted with current risk estimation tools. The biological mechanisms relating ASCVD risk factors to oxidative stress (OS) and how this accumulates ASCVD risk are misunderstood.

Purpose:

To develop a comprehensive conceptual model explaining how expanded clinical, social, and genetic ASCVD risk factors accumulate ASCVD risk through OS.

Conclusions:

OS (primarily from excess reactive oxygen species) and inflammation are present along the entire ASCVD pathophysiologic continuum. An expanded list of clinical and social ASCVD risk factors (including hypertension, obesity, diabetes, kidney disease, inflammatory diseases, substance use, poor nutrition, psychosocial stress, air pollution, race, and genetic ancestry) influence ASCVD largely through increased OS. Many risk factors exert a positive feedback mechanism to increase OS. One genetic risk factor, haptoglobin (Hp) genotype, is associated with higher ASCVD risk in diabetes and hypothesized to do the same in those with insulin resistance due to the Hp 2-2 genotype increasing OS.

Implications:

Understanding the biological mechanisms of OS informs how these ASCVD risk factors relate to each other and compound ASCVD risk. Individualized ASCVD risk estimation should include a comprehensive, holistic perspective of risk factors to better address the clinical, social, and genetic influences of OS. Preventing and reducing OS is key to preventing ASCVD development or progression.
The impact of relapse definition and measures of durability on MS clinical trial outcomes

Published: April 2023

Background:

Definitions of trial measures are consequential to accurately capturing outcomes and cross-trial comparability, particularly for derivative measures.

Objective:

Using CombiRx, examine the impact of relapse definition on endpoints and evaluate the durability of progression measures in Relapsing Remitting Multiple Sclerosis (RRMS).

Methods:

CombiRx relapse types were distinguished by the presence or timing of Expanded Disability Status Scale (EDSS) increase. Using the broadest definition of relapse, progression endpoints were assessed in patients without relapses on trial. Durability compared EDSS at study end and time of worsening.

Results:

Broadening relapse definition to the most inclusive definition increased annualized relapse rate (ARR) threefold in all arms and decreased progression independent of relapse activity (PIRA), defined as 6-month confirmed disability worsening (6M CDW) without relapse, by 44%. Neither PIRA nor PIA (progression independent of any inflammatory activity) guaranteed durable worsening, with 43% and 40%, respectively, improving by end of study. Multivariate analysis showed two CDW events, not relapse, predicted durability among patients meeting 6M CDW.

Conclusions:

The stringency of relapse definition impacted absolute ARR and composite endpoints in RRMS. Despite the most generous relapse definition, 43% of patients meeting PIRA on trial did not have durable worsening suggesting that relapse definition and durability should be considered to avoid overestimating progression in RRMS trials.
A multimodal fusion enabled ensemble approach for human activity recognition in smart homes

How to deal with multi-modality data from different types of devices is a challenging issue for accurate recognition of human activities in a smart environment. In this paper, we propose a multimodal fusion enabled ensemble approach. Firstly, useful features collected from Bluetooth beacons, binary sensors, and smart floor are extracted and presented by fuzzy logic based-method with variable-size temporal windows. Secondly, a group of support vector machine classifiers are used to perform the classification task. Finally, a weighted ensemble method is used to obtain the final prediction. Especially, by applying the geometric framework, we are able to obtain the optimal weights for the ensemble. The proposed approach is evaluated on the UJAmI dataset. The experimental results demonstrate the efficacy and robustness of the proposed method.
Creative Genre Matters: Trendy Drama and the Rise of the East Asian Global Media Market
Authors: Peng Hsin-Pey
Published: April 2023

The trendy drama, a new TV genre coined to signify contemporary trends, initially emerged in Japan in the 1980s and became popular with middle-class audiences across East Asia for portraying Western-like chic metropolitan lifestyles. This television genre typically consists of a 10 to 13 episode long miniseries with 60 to 90 minute episodes. Their narratives focus on love affairs between rich, attractive, hard-working elites as they question traditional Han Chinese values and consider whether women should be independent, allowed to work, have sex outside marriage, and divorce. While specifically Chinese, these values have influenced cultures across East Asia. While espousing liberal and feminist ideals, they roam from trendy stores, such as fashion clothing and cosmetic shops, to expensive restaurants, and back to their luxurious apartments. Quickly, these dramas became so associated with highlighting current global and local trends and countering tradition that they became known as “trendy dramas”.

This genre quickly took off and soon thereafter, South Korea and Taiwan partnered together to create their own versions of trendy dramas that helped generate much of contemporary East Asian popular culture, including the rise of K-Pop. Based on Mittell’s claim that genres function as a means of framing mass audiences’ taste, here I explore the role of this TV genre in the context of globalization and local culture in East Asia and its effect upon reshaping social meanings during the 1980s and the early 2010s. In particular, the Taiwanese trendy dramas played a key role in elevating this genre within the Asian TV market. In this article, I argue that in Japan, Taiwan, and South Korea, the trendy drama became a way to debate Han cultural values and their role in the lives of liberal metropolitan Asians. In the process, this genre helped reshape the East Asian TV market along with popular culture around the globe. I will begin by describing the history of the trendy drama before focusing on how it debates traditional beliefs and considers the value and utility of feminism and individualism in contemporary urban Asia.

Introduction:

Point-of-care ultrasound is becoming increasingly popular, and we sought to examine its role in evaluating ocular and periocular structures and facial vasculature. With the large number of point-of-care ultrasound devices available, it is difficult to determine which devices may be best suited for ophthalmic and facial aesthetic applications. This study compares five popular handheld point-of-care ultrasound devices to help guide clinicians in choosing the device best suited for their needs.

Methods:

We compared five point-of-care ultrasound devices: Butterfly IQ+ (Butterfly, Burlington, MA), L15 (Clarius Mobile Health, Vancouver, British Columbia, Canada), L20 (Clarius Mobile Health, Vancouver, British Columbia, Canada), Lumify (Philips, Amsterdam, Netherlands) and Vscan Air (GE, Boston, MA). Three ophthalmologists obtained the following views on three volunteers: eight arteries, four ocular and periocular structures and areas of filler injections. The image quality of each view was graded on a four-point Likert-type scale. In addition, graders filled out a survey. The data were analysed using analysis of variance tests with the significance level set to p < 0.05.

Results:

In terms of overall image quality, the L20 received the highest mean rating, followed by the L15, Vscan Air, Butterfly IQ+ and the Lumify ( p < 0.05). With further stratification for structure type, the L20 was ranked first for filler, artery and orbital imaging ( p < 0.05).

Conclusions:

The L20 received the highest image quality rankings. While image quality is an important aspect of point-of-care ultrasound device selection, other factors such as cost, wireless capabilities, range of presets and battery life should also be considered.
Internationalisation and English medium education in Vietnamese universities: Professional role transformation among English language lecturers

Published: April 2023

This paper investigates an emerging professional role transformation in Vietnamese universities, whereby English language teaching (ELT) lecturers transform themselves into English medium instruction (EMI) lecturers in a discipline new to them. Through interviews with five ELT/EMI lecturers working in separate universities and different disciplines, the study investigates reasons for their decision to engage in such professional mobility, their role transformation experience, and its implications for educational quality. We argue that participants’ move into EMI was shaped by the strategic imperative for higher education internationalisation, and the mistaken belief that EMI alone can achieve the English language development students require for academic success. It is also argued that the transformation option made available to the participants was not the best use of their skills, and that a profound change of perspective is needed at the institutional level to most effectively use the strengths of ELT lecturers to support educational quality.
